"Dwayne Need" already solved this problem for us.
Make sure to take a look at the PleaseWaitHelper class as well. It takes care of the creation of the PleaseWaitWindow, and allows you to show the window by using a delegate. This delegate will be executed, and as soon as the delegate is finished, PleaseWaitWindow is hidden again.
5.5. TipOfTheDayWindow
Sometimes, your end-users aren't the smartest creatures on the planet. Lots of times, I am talking to an end-user because there is a "bug" or "critical issue" that needs to be fixed right away.
During the "debug" session (read: using the software as the end-user has described), you hit a lot of key strokes and other useful shortcuts that I thought the user was already familiar with. Unfortunately, most of the time, they are not.
Therefore, the Tip of the Day window is a great way of showing the end-user some handy tips when they start your software. For example, to learn about shortcuts, "hidden" features, and more.
5.5.1. Example code
// Show window
TraceOutputWindow traceOutputWindow = new TraceOutputWindow();
5.5.2. Why?
You must be thinking: why a blog post for such an easy window? Well, because this "Tip of the Day" window has much more features than you can see on first sight. For example, have you ever thought of how to enter or manage tips? Well, this window takes care of that for you.
Simply hit CTRL + F2 when the "Tip of the Day" window is focused, and you will see the following edit mode:
With the included editor, you can simply create, modify, remove, and preview all the tips that are included with the window. The tips are stored in XML format in a subdirectory "Help".
5.6. TraceOutputWindow
The TraceOutputWindow is a debugging convenience window. It behaves exactly the same as the TraceOutputControl, but then is available as a separate window instead of an embedded control.
5.6.1. Example code
// Show window
TraceOutputWindow traceOutputWindow = new TraceOutputWindow();
5.6.2. Why?
The TraceOutputWindow allows a developer to show the trace output as a separate window and view the information when the application is actually running. The TraceOutputWindow should be preferred above the TraceOutputControl in case it can't be embedded into the software itself (for example, when a plug-in is being developed for a 3rd party application).
5.6.3. How?
The window simply wraps the TraceOutputControl into a window.
6. Themes
6.1. Shipped Themes
Catel currently ships with a single theme file. This theme file is based on the "Aero" theme that is included in the WPF libraries. The theme of Catel corrects the margins, since the default "Aero" theme sets the margin of all controls to 0, which will result in all the user controls being stuck together, as shown in the figure below:
We see too many developers fixing the margins on the control directly, while this can also be accomplished by using the Catel theme and the included StyleHelper class. See the image below for the final result:
6.2. Pixel Shaders
Catel also uses pixel shaders to apply effects to controls via themes and styles. One of the pixel shaders is, for example, the GrayscaleEffect. This effect automatically converts an image on a button to gray scale when the button is disabled. Below is an example of the shader effect:
If there are a lot of buttons used on the screen, it might be possible that the video card does not support so many shaders, and then WPF will start throwing exceptions. In that case, first try to set the shader mode of Catel to ShaderRenderMode.Software. If that doesn't work, you can turn the shaders off by using ShaderRenderMode.Off.
// Force software rendering
StyleHelper.PixelShaderMode = PixelShaderMode.Software;
// Turn off
StyleHelper.PixelShaderMode = PixelShaderMode.Off;
6.3. StyleHelper
The StyleHelper class has a few static members that will create style forwarders. Style forwarders are styles that are defined on the application level, not on the theme level. This allows you to create forwarders with the same key as the control name, but that will forward to the DefaultxxxStyle. Since the new styles are defined at the application level, you will not get any circular references because the style defined in the theme cannot access the application level resources.
This is accomplished by simply calling StyleHelper.CreateStyleForwardersForDefaultStyles(); in the OnStartup of the WPF application.
XAML (App.xaml)
 Source="/Catel.Windows;component/themes/generic.xaml" />
Code (App.xaml.cs)
namespace OverrideStyles
 ///
 /// Interaction logic for App.xaml
 ///
 public partial class App : Application
 protected override void OnStartup(StartupEventArgs e)
 // Create style forwarders

Much work, good style, easy to understand and very good ideas!
One question: You wrote about too many pixelshaders if using HW. I wonder whether it is possible to share the same pixelshader between all controls?

BHA joins with others to oppose UN Treaty against 'defamation of religions'
November 10th, 2009
The British Humanist Association (BHA), together with a number of other human rights groups and civil society organisations, has agreed to a common statement protesting against a proposed United Nations (UN) treaty to prohibit the 'defamation of religions.' The UN has continuously passed non-binding resolutions on 'defamation of religions"' since 1999. However, for the first time ever this year, a UN body proposed a binding treaty to combat the 'defamation of religions.'
Naomi Phillips, BHA Public Affairs Officer, said, 'The BHA has opposed every UN resolution that has sought to protect religion from defamation. Incitement to violence or to hatred is always deplorable but in a free society we must be allowed to criticise religious doctrines and practices, even if that offends people who consider it to be defamation of their religion or religious beliefs. Any attempt to legislate against the defamation of religion is not only dangerous but always inconsistent with fundamental freedoms and human rights.'
For further comment, contact Naomi Phillips or _PHONE_ 3585.
For more information and to read the Common Statement from Civil Society on the Concept of the "Defamation of Religions" see _URL_
Read more about the BHA's work on free speech at the international level.
United Nations resolutions on the 'defamation of religions' are incompatible with the fundamental freedoms of individuals to freely exercise and peacefully express their thoughts, ideas, and beliefs.
Unlike traditional defamation laws, which punish false statements of fact that harm individual persons, measures prohibiting the 'defamation of religions' punish the peaceful criticism of ideas. Additionally, the concept of 'defamation of religions' is fundamentally inconsistent with the universal principles outlined in the United Nations' founding documents, including the Universal Declaration of Human Rights, which affirms the protection of the rights of individuals, rather than ideas.
The British Humanist Association (BHA) is the national charity representing and supporting the non-religious and campaigning for an end to religious privilege and discrimination based on religion or belief.

Community Day Schools Program SummaryInformation on Community Day Schools purpose, services, outcomes, funding, students served, and results.
Legislation enacted in 1995 established the requirement that, at the time an expulsion of a student is ordered, the governing board of the school district shall ensure that an education program is provided to the student during the expulsion period. The same legislation authorized school districts to establish Community Day schools to serve these, and other at-risk/at-promise students. Subsequent legislation, in 1998, extended the authorization to also allow county offices of education to establish community day schools.
Students are expected to participate in academic programs that include high-level expectations from staff and students, and that are comparable to those available to students of similar age in the school district. The 360-minute minimum instructional day includes academic programs that provide challenging curriculum and individual attention to student learning modalities and abilities. Community Day schools programs also focus on the development of pro-social skills and student self-esteem and resiliency. Community Day schools are intended to have low student-teacher ratios. Students benefit from learning support services that include school counselors and psychologists, academic and vocational counselors, and student discipline personnel. Students also receive collaborative services from county offices of education, law enforcement, probation, and human services agency personnel who work with at-risk youth. Laws specific to Community Day schools are in Education Code (EC) sections 48660-48667.
The desired outcome is fully engaged students who are learning in a manner best suited to their needs. This will also result in:
- Closing the achievement gap
- Decreasing the dropout rate
- Increasing the graduation rate
Community Day schools serve:
- Expelled students
- Students referred by a School Attendance Review Board or probation
- High-risk youth referred through a district-level process who need a separate setting that is better matched to their academic, social, and emotional development needs than what can be provided in a traditional school setting.
Although the Educational Options, Student Support, and American Indian Education Office does not have specific reports on the efficacy of Community Day schools, it has prepared a research paper and compendium of resources entitled Zero Dropouts for California. This paper contains information regarding the dropout crisis; recommendations for the State, counties, districts, and the California Department of Education; and an extensive bibliography of resources.

What is the Bernstein test?
The Bernstein test (esophageal acid perfusion test) is part of a test called esophageal pH testing. It's used to see if you have gastroesophageal reflux disease (GERD), or to check to see if your symptoms are coming from the esophagus.
The most common symptom of GERD is heartburn. Heartburn can feel like a burning in your chest. You may have GERD if you have heartburn more than 2 times a week. Your healthcare provider may do a Bernstein test and other tests to be sure. However, the Bernstein test is not commonly done.
Why might I need the Bernstein test?
Some symptoms of GERD may also be signs of other diseases. Your healthcare provider may use the Bernstein test and other tests to find out what is causing your symptoms. Besides heartburn, other signs of GERD may include:
- Having a rough or raspy voice (hoarseness)
- Chest pain
- Sore throat
- Asthma or wheezing
It's important to know if you have GERD and how to control it. That can keep your symptoms from getting worse. It can also prevent more problems. If GERD is not treated for a long time it may change the lining of your food pipe (esophagus). This is known as Barrett's esophagus. It can raise your risk of getting esophageal cancer. It can also lead to inflammation in the esophagus, called erosive esophagitis.
What are the risks of the Bernstein test?There is a risk of gagging or vomiting during the Bernstein test. You may have other risks, based on your overall health. Be sure to talk with your healthcare provider about any concerns you have before your Bernstein test.
How do I get ready for the Bernstein test?
You must not eat anything for at least 8 hours before the test. This often means no food or drink after midnight.
Ask your healthcare provider to tell you what else you should do before your Bernstein test.
What happens during the Bernstein test?
Talk with your healthcare provider about what will happen and how you may feel during your Bernstein test. In general, you can expect the following:
- The doctor will insert a thin, flexible tube (nasogastric tube) through your nose into your esophagus. This may cause some choking and coughing.
- A salt water solution (mixture) and a mild acid solution (like stomach acid) will be passed through the tube at different times.
- Your doctor will ask you when you feel symptoms of heartburn or pain.
- If you do not have symptoms from these solutions, the test is negative, and you probably do not have GERD.
- If you have symptoms only from the acid solution, the test is positive, and you may have GERD.
After the test, you can go back to your normal diet. You may have a sore throat for a short while. In most cases the Bernstein test can tell if you have the disease.
The Bernstein test may be done along with other tests, such as:
- Esophageal manometry. This measures the pressure inside your esophagus.
- 24-hour esophageal acid testing. This measures the amount of acid that flows into your esophagus from your stomach over 24 hours.
- Endoscopic exam. This checks your esophagus using a thin, lighted tube.
What happens after the Bernstein test?
If you have GERD, your healthcare provider may give you medicine to lower your stomach acid level. He or she may also ask you to stop eating 3 hours before going to bed. You may also be told to raise the head of your bed. These things will help reduce your GERD symptoms.
If you have a very bad case of GERD, you may need surgery to tighten your lower esophageal sphincter (LES). This will keep stomach contents from moving up into your esophagus.
Here are some things you can do to help control GERD:
- Stop smoking.
- Lose weight if you need to and stay at a healthy weight.
- Not have too much alcohol and caffeine.
- Not eat foods that give you heartburn.
- Not wear tight clothes around your belly.
Before you agree to the test or the procedure make sure you know:
- The name of the test or procedure
- The reason you are having the test or procedure
- The risks and benefits of the test or procedure
- When and where you are to have the test or procedure and who will do it
- When and how will you get the results
- How much will you have to pay for the test or procedure

Disabling Unused Devices
If you have devices attached to your computer or installed that you do not use, you can reduce the startup time by disabling those devices. The rule to follow is to keep enabled any device that you use or might use, but if you have devices that you do not use on a regular basis, you can disable those devices without uninstalling. When you start the computer, those devices' drivers won't have to load, which will help decrease boot time.
To disable a device, follow these steps:
1. Open the Start menu, right-click My Computer, and select Properties.
2. Click the Hardware tab and click the Device Manager button.
3. Expand the category that contains the device that you want to disable.
Figure 4.12 4. Right-click the device and click Disable (see Figure 4-12). The device is now disabled and remains disabled until you re-enable it in the same manner.


Here's why we've been raising our voices for so many years and why we've said that those who came out the closet want to put us into the closet. It's why we've said that LGBT activism was never simply about "tolerance" – it was about the silencing of competing views.
In a ruling that is sure to send shock waves through the nation, Canada's Supreme Court ruled 7-2 against Trinity Western University's (TWU) Law School. In effect, what the court declared is that universities must choose between biblical standards and accreditation. Put another way, the court ruled that Christianity and higher education are incompatible. I am not exaggerating in the least.
Here's a brief summary of the case for those who are not familiar with it. Trinity Western is a Christian university that requires its students and faculty to live by basic Christian standards. This means that to be a student or faculty member in good standing, you can't commit fornication or adultery, nor can you engage in homosexual relationships.
There's nothing surprising with these requirements, and there are thousands of schools in North America with similar standards. These include Christian schools from K-12, Christian colleges, Bible schools, seminaries, and universities.
These standards have long been part of TWU's mandatory covenant, which requires "that all students and faculty pursue a holy life 'characterized by humility, self-sacrifice, mercy and justice, and mutual submission for the good of others.' It requires members to abstain from using vulgar language, lying or cheating, stealing, using degrading materials such as pornography, and 'sexual intimacy that violates the sacredness of marriage between a man and a woman.'"
Again, this is gospel 101, the basic requirements of Christian discipleship. And it is honorable that TWU seeks to live this out on its campus.
Unfortunately, when TWU opened its law school, it fell afoul of Canada's LGBT activists and their allies. They argued that TWU was discriminating against LGBT students, because of which students graduating with a bona fide law degree should not be allowed to practice law in Canada.
There was a ray of hope for TWU when a regional court ruled in its favor. But now, "In a pair of 7-2 rulings, the majority of justices found the law societies of British Columbia and Ontario have the power to refuse accreditation based on Trinity Western University's so-called community covenant."
Or, to paraphrase, the Supreme Court ruled that if a Christian law school wants accreditation, it must abandon biblical values. How else can this be interpreted?
Significant harm? If so, why? Because of biblical teaching. Because of Christian values. This is the locus of the battle. This is the point of conflict.

Parse it however you like, but this is the hardcore truth.
"[The judgment] found the public interest of the law profession gives it the right to promote equality by ensuring equal access, support diversity within the bar and prevent harm to LGBT students."
In other words, "diversity" according to the LGBT lexicon. Diversity meaning "the LGBT way or the highway." Diversity meaning, "all views are welcome other than biblical Christian views."
That's why we've been raising our voices for so many years. That's why we've been warning. That's why we've said that those who came out the closet want to put us into the closet. That's why we've said that LGBT activism was never simply about "tolerance." It was about the silencing of competing views.
And if it could happen in Canada, it could happen in America. (For the skeptics and mockers, give me one good reason why this could not happen here. And note that TWU was not some tiny school hidden in a corner. It has "40 undergraduate programs and 17 graduate programs.")
On a more personal, individual level, what happens to all the law students at TWU? What happens to those who spent years studying and invested tens of thousands of dollars in getting a law degree, only to be banned from practicing law in Canada because their school holds to Christian values? What about the significant harm experienced by them?
Honestly, I don't know where TWU goes from here. And I don't know how the believers in Canada will respond.
But I can say this to my friends and colleagues and fellow-educators and communicators here in America: We either use our liberties or lose them. We either stand fast and stand tall and stand strong, or we cower in a corner. We either do what's right today, or we apologize to our children tomorrow.
It's time to push back.

UC, SEISS payments and automatic reclaims
Sabrina Dubash describes universal credit (UC) regulations which deal with coronavirus-related payments for the self-employed and with new rules on treating a claimant as having reapplied for UC.
The coronavirus pandemic and the lockdown measures have drastically affected income for the employed and the self-employed. As a result, the government introduced schemes to help employers retain their employees/staff and provide interim replacement income for both the employed and self-employed during this difficult time.
The Coronavirus Job Retention Scheme (CRJS) was introduced for employers to claim their employees or workers furloughed pay, and the Self-Employed Income Support Scheme (SEISS) was introduced to assist the eligible self-employed with the sudden loss of profits.
Amendment regulations (The Universal Credit (Coronavirus) (Self-Employed Claimants and Reclaims) (Amendment) Regulations 2020) No.522 (the 'Amendment Regs') came into force on 21 May 2020.
The regulations ensure that a self-employed UC claimant who is also an employer and who receives payment under the CJRS scheme (ie, for her/his employees) does not have that money treated as her/his own income or capital. They also make wider provision about the treatment of SEISS income and reclaiming UC after having excess income (for all claimants, not just the self-employed).
How does UC deal with SEISS income?
Regulation 2(1)(a) of the Amendment Regs provides how SEISS income should be treated, together with regulation 57 (self-employed earnings) of the Universal Credit Regulations 2013 (the 'UC Regs 2013'). SEISS income is to be treated as 'earned income' received at Step 1 of the calculation of self-employed earnings in the assessment period in which it is received.
SEISS payments have only been paid since May 2020. Therefore, those eligible for the SEISS and awaiting payment have likely claimed UC in the interim period to assist with the sudden loss of income.
Regulation 2(1)(a) also provides that the SEISS income will be treated as income in the assessment period in which it is received, which means that self-employed UC claimants will not encounter overpayments for the periods they received UC, when they re-ceive their SEISS payments.
Regulation 2(2) provides that any payment to a self-employed claimant that is a grant or loan to cover expenses or the loss of trade due to the coronavirus outbreak is also to be disregarded for 12 months from the date it is received. This clarifies how payments received under the CRJS or the new loans and grants introduced – such as the Small Business Grant Fund, Retail Hospitality and Leisure Grant and Bounce Back Loan Scheme – will be treated for UC purposes.
Reclaiming UC
Regulation 3 of the Amendment Regs amends the Universal Credit, Personal Independence Payment, Jobseeker's Allowance and Employment and Support Allowance (Claims and Payments) Regulations 2013 No.380 and inserts a new regulation 32A:
'Reclaims of universal credit after nil award due to earnings
32A.—(1) This regulation applies where— (a) a claim is made for universal credit, but no award is made because the condition in section 5(1)(b) or 5(2)(b) of the 2012 Act (condition that the claimant's income, or joint claimants' combined income is such that the amount payable would not be less than the prescribed minimum) is not met; or (b) entitlement to an award of universal credit ceases because that condition is not met.
(2) The Secretary of State may, subject to any conditions the Secretary of State considers appropriate, treat the claimant (or joint claimants) as making a claim on the first day of each subsequent month, up to a maximum of 5, that would have been an assessment period if an award had been made or, as the case may be, if the award had continued.'
In practice, this amendment means that where a UC claim is not awarded or has terminated due to excess income ('the old claim/award'), then for the next five assessment periods immediately following, a claimant may be treated as making a new UC claim without having actually made one.
The advantages for claimants here is that where previously UC claims ended due to excess income and/or the surplus earnings rule applied,1Reg 54A Universal Credit Regulations 2013 UC claims would terminate due to excess income and the claimant would have to reclaim within six months for any surplus income to start to deplete.
The automatic reclaim for five assessment periods that follow the 'old claim/award' means that any surplus income can start to deplete from the next assessment period that follows and any entitlement to UC arising from reduced income can be made sooner. Note, however, that if the surplus earnings rule is engaged, that will continue to apply to the automatic reclaim.
Any excess income will do…
The explanatory memorandum to the Amendment Regs2legislation.gov.uk/uksi/2020/522/pdfs/uksiem_20200522_en.pdf states that the purpose of the regulations is to clarify how the SEISS and CRJS income is to be treated in the case of self-employed UC claimants. It says that regulation3Available at _URL_ government/uploads/system/uploads/attachment_data/file/8 91880/adm10-20.pdf (ie, automatic reclaims) is intended to apply only with reference to excess income following payment from the SEISS and CRJS schemes.
However, regulation 3 in fact affects all claimants whose UC claim ends due to excess income, regardless of whether they received income from the SEISS or CRJS. The regulations use the words 'earnings' and 'income', and do not specify that this income needs to be SEISS or CRJS income.
Official guidance indicates that automatic reclaims will apply in any excess income case. ADM Memo 10/203 provides examples of how the regulations will be enforced in practice to UC claims that ended due to excess income and again no reference is made to the effect that the income must derive from SEISS or CRJS payments.
A further disparity between the regulations, explanatory memorandum and the ADM Memo 10/20 concerns whether UC claims/awards that ended due to excess income before the Amendment Regs came into force on 21 May 2020 would be covered.
The official guidance says that such claims/awards are covered. ADM Memo 10/20 provides examples of how UC claims that ended due to excess income before 21 May 2020 will also be subject to the automatic reclaims for five assessment periods that follow. However, there is no specific mention of this in either the Amendment Regs themselves or the explanatory memorandum.
Following from the specific wording in the regulations and the DWP guidance, advice to claimants would be that any claim that ended due to excess income should be covered by these amendments and the automatic reclaims for up to five assessment periods they provide for.
CPAG is interested in hearing about cases where the amendments apply and how they affected your client's claim. Please email the UC London Advice Service at _EMAIL_. For more information about the service, see our website.

THE CHANGES in electrical potential along the walls of the esophagus can be expected to reflect motor activity. The electrical activity may be recorded in a manner similar to that used in recording intraluminal pressure.1,2 The present study is a comparison of hiatus hernia patients with a control group.
Combined pressure-electrode probes were used, consisting of three open-end pressure tubes placed 5 cm or 2.5 cm apart. Silver ring electrodes were mounted adjacent to the open ends for recording the pressure and electrical potentials simultaneously from the same sites.The probe was introduced perorally into the esophagus and passed to a distance of about 50 cm distal to the upper incisor teeth. It was then withdrawn until the distal probe end was located 40 cm from the incisors. The external portion of the probe was taped to the chin.

Vaccination of the Nation
To date Australia has fared relatively well by international standards in terms of its COVID-19 infection rates. Now, however, its vaccination progress does not compare so favourably to other countries. Charts showing Australia languishing at the bottom of a vaccination league table have been circulating widely online. The specimen below, which appeared in last weekend's Saturday Paper, is a typical example.

The challenge when producing charts like this is that there are far too many countries to squeeze onto a bar chart, requiring a somewhat arbitrary choice of the countries to include. This chart suggests that Australia's full vaccination rate is the worst and Chile's is the best. Australia does not in fact have the lowest rate in the world, although it is the lowest among OECD countries. Chile, at the other end, is certainly doing very well, but is not the best in the world – that honour sits with Gibraltar (or Malta if we restrict to sovereign nations). Even considering only OECD countries, the chart omits Iceland and Israel which are both a little ahead of Chile.
So, how can we get a better picture covering all countries around the world? One approach is to use a map instead of a bar chart. The map below shows countries grouped into quintiles (five of them, of course), ranging from the 20% of countries with the lowest rates of vaccination through to the 20% of countries with the highest rates. On this basis, with a full vaccination rate of 7%, Australia just scrapes into the middle quintile along with countries with full vaccination rates ranging from 6-18%. So Australia may not be last in this "race", but the countries with lower rates are all far poorer than Australia.
The striking band of top quintile blue between Russia and China is Mongolia, which has an interesting story behind its vaccination success (thanks to Dan for alerting me to that article).

Some notes on the data:
 1. The data here is all sourced from Our World in Data (OWID), which in turn sources data from national authorities. A significant number of countries do not appear in the dataset and these are likely to be countries with very low rates of vaccination. If this data were available it would push up Australia's ranking.
 2. "Countries" includes dependencies (such as Gibraltar) and disputed territories not just widely recognised sovereign nations.
 3. OWID reports a vaccination rate for Gibraltar of over 100%. This appears to be because vaccination figures include guest workers and, given Gibraltar's small population, this has a big impact on the rate. Since there continue to be some cases of COVID-19 among unvaccinated people in Gibraltar, the true rate must be below 100% but as I have seen some estimates that the figure is more like 90%, Gibraltar is probably still in the lead.

 Welcome back. Some thoughts:
 1. I wonder if it is possible to plot the above map using a population weighted cartogram?
 2. If you plot the following data from OWID downloaded on 29/6/2021 for OECD countries the R^2 is 0.39. The plot of vaccination rates vs case rates is consistent with a significant driver of vaccination rates being case rates, at least for well off OECD countries. My hypothesis is that countries that have seen a lot of Covid have governments with more imperative to vaccinate sooner and perhaps lower rates of vaccine hesitancy. 5 of the 6 lowest case rate countries: Australia, NZ, Japan, South Korea and Mexico are also the 5 lowest vaccinated countries. The other is Finland which according to Monty Python is the country "where I want to be" because it has "Pony trekking or camping or just watching T.V." All socially distant activities which may explain their low case numbers.
 1. vaccination rates should be 200 per 100 people for a fully vaccinated pop'n ie where everyone has had two jabs.
 2. Iceland Colombia are excluded.

 James: I used QGIS to produce the map and, while it focuses on producing very accurate maps, I believe there is a cartogram plugin, so I will look into that. Good point on the correlation: I suspect that low case rates can lead to complacency on vaccines but as many countries have found, the case rate can get away from you very quickly. On the vaccination rates, OWID publishes two different figures: "total_vaccinations_per_hundred" and "people_fully_vaccinated_per_hundred", the former would be around 200% for full vaccination (although I'm not sure how they've treated the one shot J&J vaccine) but the latter – which is the one I used for the map – would be 100%.

The widely distributed ant genus Tetramorium is among the most species-rich ant genera in the world. Currently, we know 600 species, but scientists expect the total count to be closer to 700 or more species. Most of those species are found in the tropics and subtropics and Madagascar is the place where it is by far the most species-rich ant genus.
Colleagues have now found and described a new member of the genus: Tetramorium cavernicola
The name of the new species is Latin and means "cave dweller" or "cave inhabitant". It refers to the fact that the species is known only from a cave in Ankarana.
Abstract: In this study we provide an update to the taxonomy of the ant genus Tetramorium Mayr in Madagascar. We report the first record of the T. setigerum species group in Madagascar and describe the only Malagasy representative as T. cavernicola sp. n., which is known only from a cave in Ankarana. In addition, we provide an overview of the 19 proposed Malagasy species groups, and discuss their zoogeography and relationships to other groups and larger lineages within the hyper-diverse genus Tetramorium. At present, we recognise a highly unique Malagasy Tetramorium fauna with 113 species endemic to the island of Madagascar out of a total of 125 translating into an endemism rate of 93%. We hypothesise that this fauna is based on one or a few colonisation events from the Afrotropical region, with subsequent adaptive radiation in Madagascar. Furthermore, we present an updated and illustrated identification key to the Tetramorium species groups in the Malagasy region.

The building emission reduction potential of South African residential building efficiency tools – A review
Keywords:building energy efficiency tools, climate change mitigation, green buildings, residential sector
The building sector's levels of greenhouse gas emissions and energy consumption are a significant contributor to South Africa's overall carbon emissions. This influences the country's ability to meet its commitments to the Paris Agreement, which aims to limit the effects of global climate change. This review article focuses on the climate change mitigation strategies that are employed by the building sector, specifically the potential impact of mandatory and voluntary building energy efficiency regulations, standards, initiatives, and certifications common to South Africa's residential market. International research on the impact of green building tools tends to focus on the commercial rather than the residential sector, due to limited energy data availability. Within this context and given the exploratory and evaluative nature of the present research endeavour, substantial reliance has had to be made on a number of grey literature for this research. A review of the South African building efficiency tools shows that there is potential for a 16% reduction in the energy intensity of the residential sector by 2030. This will, however, be offset by the projected increased building floor area and is as such insufficient to meet South Africa's commitments to the Paris Agreement. Thus, more ambitious targets are required. Given the growth of the residential sector and the potential impact of the various tools, a focus on improved and timeous mandatory regulations for new builds is crucial, in order to meet our climate commitments.

why are the product-rules as they are?greenspun.com : LUSENET : quaternions : One Thread
A short historical intro: When Hamilton was thinking about the 3D-complex number x+iy+jz he (1)assumed jj=-1 and (2)added a fourth complex number k so ij=k (et voila, quaternions).
I was wondering why he made these choices (1) and (2). Because when you write down the productmatrix for x+iy+jz it looks very logical to choose the following products: ii=j, jj=-i and ij=ji=-1. Was this ever an option, does it not make any sence, or what?
PS: You can make the mandelbrot fractal in 3D with these rules (as I have done using Mathematica, notebook available).
-- Jan Harm Moes (_EMAIL_), January 20, 2005
Hamilton was trying to accomplish two objectives. The first was to parallel normal complex number arithmetic where:
C= a + ib C*= a - ib
(C)(C*)= a^2 + b^2
as you can see if you do the multiplication. If you create a hyper-complex number, and want the same result, you won't get it:
H= a + ib + jc H*= a - ib - jc (H)(H*)= a^2 + b^2 + c^2 - 2ijbc
That extra term, 2ijbc is the killer. You want to get rid of that, and the only way to do so is to stipulate that: ij= -ji. Your alternative, even though it is logical, doesn't do this, since if: ij= ji= -1, then: (H)(H*)= a^2 + b^2 + c^2 + 2bc.
Secondly, Hamilton wanted a complex number arithmetic analog of 3-D vector arithmetic. Hamilton's rules:
i^2= j^2= k^2= ijk= -1
accomplish this. If you do the multiplication on a hyper-complex where these rules apply:
H= a + ib + jc + kd H*= a - ib - jc - kd
(H)(H*)= a^2 + b^2 + c^2 + d^2
where the other terms containing complex components cancel out since they occur in anti-commutative pairs. If you do the actual arithmetic, you will see that you get these rules:
ij= k ji= -k jk= i kj= -i ki= j ik= -j
These parallel the cross products of the unit vectors in the Cartesian system:
u(y) X u(z)= u(x) u(z) X u(y)= -u(x) u(z) X u(x)= u(y) u(x) X u(z)= -u(y) u(x) X u(y)= u(z) u(y) X u(x)= -u(z)
What you proposed does not: ii= j doesn't compare to u(x) X u(x)= 0. This also can't be a dot-product, since dotting vectors gives a scalar, not another vector. While your rules are logical, and may have applications; paralleling vector arithmetic isn't one of them.

The structure and surface morphology of these samples were analyzed by Scanning Electron Microscopy (SEM), Transmission Electron Microscope (TEM) and XRD. The influences of the impact angle and acidity on erosion wear property were analyzed. The discipline of the erosion wear property was discussed as well. The experimental results indicate that after oil quench at 960°C and temper at 250°C, the alloy carbide (Fe, Cr)3C which works as the wear resistance skeleton distributes uniformly in the matrix ; the shape of erosion wear curve is "M". and the biggest wear loss is when the impact angle is 60°; the erosion wear property is affected greatly by the strong acid, but is little even can be ignored when pH≥3. The erosion wear mechanism of Nickel-Chromium cast iron is selective wear.

This dissertation addresses two critical issues in the mechanical behaviors and structures of bulk-metallic glasses (BMGs): (1) the effect of composition, fabrication method, and pretreatment of plastic deformation on mechanical properties and structures of BMGs; (2) the mechanical response and structural evolution of BMGs in the elastic and plastic region.
(Cu50Zr50)94Al6 and (Cu50Zr50)92Al8 amorphous alloys were used to study the effect of composition on mechanical properties and structures of BMGs. The (Cu50Zr50)94Al6 alloy exhibits lower yield stress and Young's modulus, higher Poisson's ratio, worse thermal stability, and better plasticity than (Cu50Zr50)92Al8. Both the topological and chemical effects of Al addition account for the differences of mechanical and physical properties between them.
A Zr55Ni5Al10Cu30 glass-forming alloy with injection casting (the melting temperatures are 1,550 K and 1,250 K, respectively) and with suction casting was fabricated. The results indicate that despite their amorphous structures, the suction-casting samples exhibit a lower yield stress, lower Young's modulus, and larger plastic strain than the injection-casting samples (the melting temperature is 1,550 K) due to more quenched-in free volumes in suction casting, which results from the higher cooling rate.
The inhomogeneous plastic deformation in Zr50Cu40Al10 BMG samples was introduced by four-point-bend fatigue. There is almost no difference of the stress-strain behaviors between the deformed and undeformed samples. Elastostatic compression was used to introduce homogeneous deformation in Zr70Cu6Ni16Al8 BMG samples. The preloaded samples are softer with decreases of yield strength and Young's moduli. Anisotropy was observed in the preloaded samples despite their small magnitudes, which even occurred at a relatively low temperature and applied stress level.
The structural evolution of Zr70Cu6Ni16Al8 BMG in the elastic region was analyzed with anisotropic pair density function. The analysis of the first shell of Zr70Cu6Ni16Al8 glass confirms the structural changes in the elastic region. The bond reorientation leads to direction dependent changes in the chemical short-range order. The structural evolution in the plastic region of Zr70Cu6Ni16Al8 BMG is investigated as well. The serrations were observed for both the stress-displacement and full width at half maximum-displacement curves. The excess free volume was measured, which increases with increasing the displacement.

At their eighth meeting, the Parties agreed to focus their efforts on a few key activities to advance the programme of work for CEPA. Education was one of these elements. Parties agreed that they would:
"Taking into account the importance of both formal and informal education, initiate programmes to strengthen formal and informal education on biodiversity,"
- Ensure that these programmes are informed by and linked with the UNESCO Decade of Education for Sustainable Development
- Identify best practices in biodiversity education, including those initiated by indigenous and local communities, and seek to disseminate these for further adoption.
- Education on biodiversity should seek to communicate, in language and methods suitable to a variety of age groups and communities:
- Biological Diversity and its role in sustaining human well-being.
- The importance of the interlinkage between conservation, sustainable use and equitable sharing of the benefits from the use of biological resources.
- Ways that people can identify and monitor biodiversity in the ecosystems in which they live
- Local and traditional knowledge about biodiversity.
To this end, Parties agreed that they should:
- Taking into account the best practices at the international and national level, and drawing upon local experiences, initiate pilot projects for the strengthening of biodiversity education;
- Encourage partnerships among Parties, Governments and stakeholders for the development of generic K-university biodiversity-related curricula for use at the national and regional levels;
- Share best practices with parties through the CEPA portal.
- Evaluate pilot projects with a view to extend implementation as specified in the plan of implementation for CEPA
The Executive Secretary committed to working with UNESCO and other international organisations to identify best practices and ensure their diffusion to Parties.
In March of 2008, UNESCO and the Secretariat, with the financial support of the government of the Netherlands, held an expert workshop on biodiversity and formal and informal education. Read the main conclusions

Economic Policy Review Executive Summary
When the Back Office Moved to the Front Burner:
Settlement Fails in the Treasury Market after 9/11
Recapping an article from the November 2002 issue
Contact Authors
E-mail authors
23 pages / 251 kb
Authors: Michael J. Fleming and Kenneth D. Garbade
Index of executive summaries
Fleming and Garbade explain why a high rate of settlement fails persisted after September11 despite actions by the Federal Reserve and market participants to ameliorate the problems caused by the attack on the World Trade Center. They argue that fails rose initially as a result of the destruction of records and communication facilities, but remained high because the means typically used to avert or remedy fails—borrowing a security though a special collateral repurchase agreement—proved as costly as failing to deliver the security.
The magnitude of the settlement fails problem that arose in the aftermath of the attack was unprecedented in the history of the Treasury securities market and led Treasury to reopen the actively traded ten-year note with only two hours' notice to market participants. Both the size of the problem and Treasury's strong response make understanding the origins and context of the settlement fails problem particularly important.
Argument and Methodology
Fleming and Garbade begin their analysis with an overview of the settlement process in the Treasury securities market. They explain how settlement fails occur in the normal course of market functioning and describe the role of special collateral repurchase agreements in avoiding and remedying fails (exhibit).
The authors then describe the initial effects of the September11 attack on the settlement process. The destruction of trade records, brokers' offices, and communication facilities caused settlement fails to soar. For the week ending September19, fails averaged $190billion per day, far exceeding the $7.3billion daily average for the first eight months of 2001 (chart). The Federal Reserve responded quickly by suspending selected limits on its securities lending program, thereby making collateral more readily available to primary dealers. Concurrently, market participants worked to resolve the communication and operational problems caused by the attack.
Fleming and Garbade go on to show that despite these steps, settlement fails continued at a high rate through the end of September. The authors argue that fails remained high because a relatively low federal funds rate and investor reluctance to lend securities kept the rates on special collateral repurchase agreements at or near zero. With such low "specials" rates, investors had little incentive to borrow the securities they needed to settle earlier trades.
As concern grew that the level of fails was undermining market functioning, Treasury officials took the unprecedented action of reopening the ten-year note with only two hours' notice. The additional supply raised the note's specials rate and increased investors' incentives to settle their trades. Thereafter, fails declined quickly, dropping from a daily average of $142billion during the week ending October3 to $63billion per day the next week, and then to roughly $18billion per day in each of the following two weeks (chart).
The authors attribute the persistence of fails following September11 to specials rates that were near zero for several actively traded securities. In effect, the cost of borrowing securities to avert or remedy a fail during this period was virtually as high as the cost of failing. Treasury's action to reopen the ten-year note raised the specials rate and made borrowing the note more attractive than failing.
Fleming and Garbade conclude their analysis with a look at long-run reforms to alleviate chronic fails. One initiative considered is the creation of a Treasury facility that could lend specific securities on a temporary basis during periods of high demand. Chronic fails could also be reduced, the authors suggest, through the institution of a penalty fee for fails.
Fails may be remedied by borrowing the needed security through a special collateral repurchase agreement. In the second section of the exhibit below, B remedies its fail to investorC by "reversing in" bonds from investorD and delivering the borrowed bonds to C.
Borrowing Securities to Cure a Settlement Fail
Settlement fails reached their peak immediately after the September attacks and remained high until early October, when Treasury reopened the on-the-run ten-year note.

O Romeo, Romeo! Wherefore art thou Romeo?
I remember learning in high school that when Juliet utters these words it doesn't really mean what it's often interpreted to mean. Hers is not a question about Romeo's location, nor even predominantly an expression of distress that he isn't present. What it is is an ontological question: why, she wonders, must he be not where, but what he is — a Montague who has stolen her heart.
Even so, there have been versions of this scene staged such that Juliet appears to be looking around from the balcony for her lover as she speaks the famous lines. This misdirection obviously fogs the fundamental character of Juliet's angst.
Well, I've got some angst of my own (though in deference to my neighbors I don't intend to deliver it from my second floor window), and I can't help but think of the parallels with the above misinterpretation as I observe the debate over "intelligent design" (ID).
I know it's often an imprudent digression to quibble over words, but in this case my quibble is one that goes to the foundations of how we frame the discussion of ID: Wherefore, I might ask, art thou design?
And of course I mean the question in exactly the same sense Shakespeare intended for Juliet's plaint. I'm not interested in the "where," in discovering or dithering over putative examples of design. That is putting the cart before the horse. I am interested in the "what" and the "why" involved in how such phenomena come to be so designated. It seems to me that we regard the question of whether something may reasonably be described as "design," or even as "looking designed," with far too little skepticism.
'Tis but thy name?'
Many, probably most, scientists have at one time or another used convenient language that seems to impute a telos to biological processes (e.g., a gene "wants" to propagate itself). Perhaps it's this kind of casual reference that allows comfort with "design" language. Nearly everyone is familiar with this from Richard Dawkins The Blind Watchmaker:
"Biology is the study of complicated things that give the appearance of having been designed for a purpose." (Dawkins, 1986)
This passage has been quoted in many a creationist tome and on many a creationist web page. We all know that Dawkins is not saying that things are designed; he's saying things look like they are designed. And we all know that The Blind Watchmaker, like many of his books that followed, was an attempt to elucidate this distinction:
"The purpose of this book is to resolve this paradox to the satisfaction of the reader, and the purpose of this chapter is further to impress the reader with the power of the illusion of design." (Ibid)
Like Dawkins, many evolutionary pundits seem to believe that the real debate begins subsequent to tacit acquiescence to design (if only "the appearance of"). However, the argument I'd like to make is that the word "design" should be avoided altogether. It should stick in the throat of any critic of ID. My reasons for this are twofold:
First: To someone who already believes in a creative deity the use of the word "design," even in the context of (what they would perceive as) equivocation over real or apparent, is a very real concession to the "obvious" facts of the matter:
"Design should not be overlooked simply because it's so obvious." (Behe, 2005)
"In short, design is "obvious"; the question is only whether it is real or apparent." (Pearcey, 2000)
"Design is obvious at a glance to anyone, and detailed scientific analysis has not changed that fact." (Snoke, 2001)
I think a significant portion of this debate is lost when we routinely refer to biological complexity as "designed," even with appropriate (for those thinking critically) qualification. Ceding the use of that word presents some semantic obstacles, and it supports the believer's conceit that this phenomenon is plain even to atheists who then manage to don blinders due to arrogance and intransigence. But more fundamentally, I think granting design language leaves creationists on philosophically safe ground. It passes up an opportunity to put them in a position where they have to acknowledge that ideology is informing their perspective on the "design" analogy (more on this to follow). When we use this terminology, we encourage a rhetorical sigh of relief and the attitude that "Now, all we have to do is offer design examples" (of which they, of course, can claim a nearly inexhaustible supply).
And second: The biological world doesn't even look designed. The word is simply inapt.
What's design?
It is nor stone, nor stream, Nor fish, nor man, nor any other part belonging to the world. [Apologies to the Bard of Avon]
One finds the quality of "purpose" inherent in any definition of the word design. Design inevitably reflects intent. And we know that this is the use of "design" ID proponents mean to offer. The entire thrust of their ideology, from kvetching about the "mindless purposelessness" of Darwinian evolution to kibbitzing about the unfair restrictions of methodological naturalism, is to clear a little space where they can stuff some transcendent intentionality back into the evolution of life. It's well understood that there is no empirical warrant for concluding this world's biota is the result of purpose, and my point in broaching intent is to show that neither is there any logical warrant for suggesting it appears to be so.
To grant the observation that life appears designed is to assert that there are diagnostic hallmarks we can find in designed things (the only examples of which we can evaluate being human derived) that we also discover in the biological world. What might some of these be? Complexity? No, simplicity is every bit as likely to be the result of the designing process. Specificity? Not really. As it is defined and used by ID proponents (an "independently given pattern") this is a rather meaningless concept that reduces to "I know it when I see it." And so in trying to adduce "design" in non-human artifacts using specificity as an indicator is essentially an exercise in begging the question. Perhaps irreducibility? Actual design may or may not be overtly irreducible. Irreducibility in a design can be obscured because it may be subject to the purpose of the designer (e.g., an apparently redundant part of a system may actually be entirely necessary based upon the intended life expectancy of the system). Thus irreducibility in design can be enigmatic absent knowledge of purpose. Add to this the fact that undirected natural forces have been shown to be capable of producing irreducibility and it becomes clear that this quality may be present in designed things, but it is not diagnostic of design.
Robustness? Well, of course this is a relative concept, i.e. robust compared to what, and in what sense? That of withstanding physical forces, making slim resources last, or even being long-lived? It's true that these qualities can be found in things we know to be designed, but so are their opposites. It doesn't seem that we can say robustness is diagnostic of design. How about redundancy? I don't think so. Cost/benefit considerations will cause redundancy to be "designed out" wherever it pays to do so. Maybe, then, organization? Well, as with irreducibility we know that there are undirected physical processes that can produce organization in nature, e.g. crystals, concentric circles on water surfaces, or fractal systems. So no, organization won't work.
Hmm... beauty? No. Convenience? Not necessarily. Ubiquity, rarity? Nope.
The scope of the design act is breathtaking. It can be as simple as enhancing a mood by moving one stone in a Zen garden, or as overwhelming in complexity as conceiving the space shuttle. The diagnostic commonality here has nothing to do with material or manufacture, nothing to do with specificity or irreducibility or organization or any attempted combination of these and other qualities. The diagnostic commonality in design is intent. We know that something is designed when we understand the deliberation that produced it. Design is the expression of purpose. And the truth is there is only one way we can know that purpose is inherent in any act or artifact, and that is to know something of the designer. When we recognize design, it is either because we are familiar with similar systems or structures that we know to be designed, or we are familiar with the design processes that might have produced it. All such familiarity is based, at root, upon knowledge of the designers.
But as we have no evidence whatsoever of ID's designer, we are left without any insight into putative purpose. We know nothing that justifies an inference to "design" in nature. And except for that which they import from their personal philosophical convictions, neither do ID proponents. So they try to square this circle with the assertion that this intent is "obvious" in all that surrounds us.
There is nothing - not one thing - in


In a short form "Trekking is an act of walking for pleasure".
Trekking is walking along the mountain/ Hill / Himalayan trails for pleasure or sports. It provides an opportunity to explore the villages, villagers, valleys, mountains and its interior. So trekking means foot travel on mountain trails.
The Wikipedia's definition of trekking: "Trekking is a form of walking, undertaken with the specific purpose of exploring and enjoying the scenery. It usually takes place on trails in areas of relatively unspoiled wilderness. "

This example shows how to use the blocks in Linear Analysis Plots and Model Verification libraries of Simulink Control Design. The Simulink Control Design software provides blocks that you can add to Simulink models to check that the model's linear response satisfies frequency-domain characteristics during simulation. In this example, the gain and phase margins of an aircraft velocity control loop are checked as the fuel load changes.
Open the Simulink model of an aircraft:
The aircraft model is based on a long-haul passenger aircraft flying at cruising altitude and speed. The aircraft starts with a full fuel load and follows a pre-specified eight hour velocity profile. The Simulink model is a much simplified version of a velocity control loop which adjusts the fuel flow rate to control the aircraft velocity. The model includes elements to model fuel consumption and resulting changes in aircraft mass as well as nonlinear draft effects limiting aircraft velocity. Constants used in the model, such as the drag coefficient, are defined in the model workspace and initialized from a script.
The aircraft model contains a
Check Gain and Phase Margins block from the Simulink Control Design Model Verification library. This block computes the linearization of the loop seen by the
Velocity Controller block every 30 minutes of simulated time.
The block computes the loop gain and phase margins and checks that:
The gain margin is greater than 30 dB
The phase margin is greater than 60 degrees
When computing the margins, the loop feedback sign must be specified. To determine the feedback sign, check if the path defined by the IOs includes the feedback summation:
If the path includes the summation block, use positive feedback.
If the path does not include the summation block, use the feedback defined by the summation block.
The linearization IOs specified in the
Check Gain and Phase Margins block includes the summation block with negative feedback. Therefore, the feedback sign used to compute the gain and phase margins must be positive.
The block shows the computed gain and phase margins in a tabular format. Clicking Show Plot button opens the tabular display.
The Assertion tab in the block specifies that a warning be thrown when the assertion fails, i.e., the gain and phase margins are not satisfied.
The model also includes a
Nichols Plot block from the Simulink Control Design Linear Analysis Plots library, which computes the loop response as the fuel mass drops during the simulation. The
Generate dynamic range events block generates a rising edge whenever the fuel mass is a multiple of 10% of the maximum fuel mass. These rising edges trigger a linearization and display the results on the Nichols plot. The Show Plot in the Block Parameters dialog box opens the Nichols plot.
Signal Builder block in the model defines the velocity profile for the aircraft. Double click the block to show the Verification Manager Tool which displays the check blocks included in the model. See Construct Simulation Tests by Using the Verification Manager (Simulink) for more information.
To check if the specified gain and phase margins are satisfied, simulate the model by clicking the
Start simulation button in the
Signal Builder block window or the Simulink model.
Warning: Assertion detected in'scdaircraft/Check Gain and Phase Margins' at time 27020.4
The tabular display shows:
The times when the control loop is linearized.
The computed gain and phase margins.
Margins that violate the specified bounds are shown in red. The phase margin bound is violated towards the end of the simulation when the fuel mass and airplane velocity have dropped. The Nichols plot indicates the small loop response variations as the fuel load and aircraft velocity change.
The table shows that the linearizations are not computed at exactly every 30 min but at small variations of 30 min. This is because zero-crossing detection for the block is not enabled. Enabling zero-crossing for the block ensures that the linearizations are computed at exactly 30 min intervals but may increase the time the simulation takes to run.
You can select the Enable zero-crossing detection option in the Block Parameters dialog box or use the block command line API to enable zero-crossing detection:
set_param('scdaircraft/Check Gain and Phase Margins','ZeroCross','on') sim('scdaircraft');
Warning: Assertion detected in'scdaircraft/Check Gain and Phase Margins' at time 27000
The Logging tab in the
Check Gain and Phase Margins block specifies that the computed linear systems be saved to a workspace variable.
The linear systems are logged in a structure with
LinearAircraft = struct with fields: time: [17x1 double] values: [1x1x17x1 ss] blockName:'scdaircraft/Check Gain and Phase Margins' assertionValue: [17x1 logical]
values field stores the linear systems as an array of LTI state-space systems. For more information, see Model Arrays (Control System Toolbox).
You can retrieve the individual systems by indexing into the
L = LinearAircraft.values(:,:,17)
L = A = scdaircraft/ scdaircraft/ scdaircraft/ scdaircraft/ -0.01122 0 0 scdaircraft/ -0.01184 0 0 scdaircraft/ 0.7492 0 -0.4326 B = Velocity Con scdaircraft/ 0.3774 scdaircraft/ 0 scdaircraft/ 0 C = scdaircraft/ scdaircraft/ scdaircraft/ Velocity Con -1.998e-15 1 -0.4326 D = Velocity Con Velocity Con 0 Continuous-time state-space model.

This week's feature is the fourth and final in our series on food security. The first part looked at a Canadian perspective, the second looked at organic farms in New Orleans. and the third looked at composting. This week's is about reducing waste.
Can we live waste-free in a world where most goods come packaged, and throwing stuff away allows us to forget about it? We need to change the way we think about waste and reduce the amount of waste we produce.
To promote this waste-free lifestyle, the University of Calgary sustainability street team invited U of C students, staff and faculty to participate in the Clean Bin Challenge between Feb. 27–March 26 during which they would live for one month without producing any waste — attempting to have a clean bin. The participant who produces the least amount of waste by weight will be declared the winner.
This Clean Bin Challenge was inspired by the 2010 Clean Bin Project documentary. The documentary follows Jen Rustemeyer and Grant Baldwin as they compete against each other to see who can produce the least amount of waste over a year. The documentary examines waste problems, such as the Pacific trash island and offers ways we can reduce waste.
Rustemeyer and Baldwin show how difficult minimizing waste production can be and consider whether their tiny green actions will actually influence the large environmental problems caused by what they call our "throw-away society," where materials are used once and then discarded, without consideration given to reusing it.
Deven Biskup, a fourth-year U of C history student, commented that tracking how much waste he produces is hard since there are two different bins in his back yard, and his household garbage is taken out constantly. He's never had the chance to see all his waste together in one place.
Reducing waste production is difficult because buying products with a lot of packaging is very convenient. When getting food is easy, consumers hardly stop and think about the amount of waste produced. For example, take-out boxes provide convenient food but go straight to the trash. Consumers need to think about the production, packaging and disposal of goods. When buying a product, one is purchasing the packaging too.
Ryan Petrushka, a third-year U of C geoscience student, said "[I have to] be more careful with what I buy, eliminate the source of it, not have as much food that I won't be eating, because the food comes inside packaging and this is waste."
The packaging of food, clothing, electronics and other material goods has to be recognized as waste. Kenneth Marsh and Betty Bugusu from the Institute of Food Technologists found that 31 per cent of all municipal solid waste comes from packaging. In addition, food packaging contributes more waste to landfills than any other type of packaging.
In 2007, Claire Bassett and Angela Charlton published the War on Waste for the U.K. government, which studies the amount of food packaging in grocery stores. Twenty-nine similar items from eight different stores were compared. The study found that about 5 per cent of the total weight of groceries was food packaging, and 21–40 per cent of this packaging could not be recycled.
"The quantity of waste I produce is mostly food waste," said Biskup. A common misconception is to think that food and water are waste. When consumers don't think about packaging, their perspective doesn't encompass waste fully, so consumers think they produce less waste than they actually do.
Most food in Canada comes packaged, and the packaging will usually end up in the garbage. For example, the plastic bottle that water comes in will soon be thrown out. Both the paper bag used for a muffin and the disposable coffee cup go into the garbage. These small, one-time use products add up very quickly.
Why do we need so much packaging? Packaging allows food to be preserved longer and allows for food to be transported farther distances. However, packaging is often just there to make carrying the product home convenient.
In addition to this, the U.K. government's Waste and Resources Action Program showed that luxurious packaging attracts consumers. Consumers often choose packaged goods over loose goods. In other words, consumers are willing to buy a product because of the packaging — the marketing on packaging helps to sell it.
How can packaging be improved? "Creating a food package is as much art as science," wrote Marsh and Bugusu. Packaging has to be efficient and maintain the quality and safety of food to be considered an ideal food package. Waste-reducing packaging is a "shared responsibility between producers, retailers, consumers, local authorities and the waste management industry." Producers should promote the use of more recycled materials in the components of the packaging as well as design efficient packaging. Retailers should reduce packaging and research and market products that are less wasteful. Consumers should reduce their demand for packaging. Local authorities should provide recycling facilities and waste education for their residents. Industry should invest in facilities to recycle and recover waste.
Even if a consumer is aware of the waste problem, they still have to purchase the packaging in order to obtain the product. Until the food industry comes up with an ideal packaging system, the responsibility to reduce waste is on consumers.
How can consumers reduce packaging waste? How will the competitors of the Clean Bin Challenge skip purchasing waste if almost everything comes wrapped in some kind of packaging?
In three weeks of competition, the participants have had difficulties with food packaging, but are reducing their waste by being creative and organized. The Clean Bin Project documentary offered several ways that anyone concerned about the amount of waste they produce can reduce that amount.
An important first strategy is to stop using plastic bags. Most people use plastic bags to take their food home and sometimes the bags are doubled. Cloth bags are much more durable and can usually hold more, so switching to them can be more efficient. According to the Clean Bin Project, an average person uses 500 plastic bags per year and fewer than 1 per cent of these are recycled.
Michele Mallinson, a geoscience and paleontology student who is participating in the challenge, said, "If you could go to a natural place and even bring your own plastic bags, then you can just bulk it."
The documentary also recommends thinking about packaging before buying a product.
"I am a vegetarian, but I cannot buy veggie beef in bulk, like meat, so it comes with the plastic packaging," said Nasrin Pak, a participant and a U of C physics graduate student.
Janice Cook, another participant and a U of C kinesiology professor, faced the same problem, but with fish. If she shops at a grocery store, the salmon she wants comes wrapped in cellophane, with styrofoam and plastic pads.
Another strategy to reduce waste is to have recycling bins handy at home, and to recycle everything possible. Pak, as well as Mallinson, commented that they have become more aware of recycling materials because of the challenge.
"You have to look at your garbage and see what is recyclable, if you have a pop can then you know you can take it back to the bottle depot, you just have to watch what you are throwing away," said Mallinson.
According to the City of Calgary, about 80 per cent of the total municipal solid waste goes straight into landfills, leaving only 20 per cent in the blue carts for recycling. Waste sorting is the responsibility of every citizen — things that can be reused, recycled and composted should be put in their appropriate place.
Yet reducing packaging is preferable to recycling. Emma Cook-Clarke, a Clean Bin Challenge participant and first-year U of C environmental science student, said, "Even the recyclable things, they still have so much packaging. I bought some rice and it was in a square plastic container, but the plastic was so thick and it seemed really unnecessary. It doesn't make any sense to have all this for a product you will use once."
Considering if a product is actually needed before it is used reduces waste. Cook said that she was inspired to prepare food differently. For example, she no longer uses aluminum foil to cook. She also decided to use handkerchiefs because she realized she wastes too much tissue.
"Twist ties are the other thing I noticed. Is it really necessary when you could just make a knot to close the bag? The challenge makes sure you are aware of the little things," said Cook.
Composting and making some products yourself can further reduce waste. Pak started composting her organics and Mallinson started producing her own homemade soaps.
Going to farmers' markets instead of regular grocery stores can also help. Farmers' markets are a local and healthy alternative, but they are also a waste-reducing business. Products use less packaging because they travel short distances and they don't need to be packed in a special way to protect them for long-distance transportation. The products are harvested and are only kept in a cooler for 2–3 days, so packaging is not needed in order to preserve the food.
One of the most important ways to reduce waste is to better educate oneself about the problem.
"The challenge makes you become aware of all your choices, and it can't be an isolated point — you have to look through all your lifestyle habits," said Cook.
Cook-Clarke is also seeing the challenge as a lifestyle change, and that waste needs to be reduced in an inter-connected way, instead of isolated parts.
"We don't see where our garbage goes and this is a huge issue. Once the garbage truck comes and takes it away, it's like we are done with it and we don't have to see the effects at all. Until you see that the environment is being ruined because of the garbage, you don't really realize the effect that the excessive amount of garbage makes," said Cook-Clarke.
Once something is thrown in the garbage, the problem does not end — the problem is just beginning

When it comes to high impact communication it is hard to surpass the power of TED. Not only are the pithy 17 minute presentations a mark of high credibility, the tight format and preparation that goes into a TED or even an affiliate TEDx speech results in an outcome that is destined to influence thousands (or even millions) of people for years to come. As an entrepreneur and especially as a communicator it is worth your while to hone the ability to "talk like TED" regardless of where you present. As a longer term goal, consider preparing and applying to speak at a TED or TEDx program as well.
In the meantime, here are 10 TED Talks that clearly qualify as ideas worth spreading. I invite you to listen, learn and share the following presentations that will inspire you to take positive actions right now:
1. Why You Should Let Your Fears Guide You | Leonard Kim
Chances are, you aren't fearless. And if you are, you may be missing a part of your amygdala, the reptilian portion of your brain. You may act fearless at times, but deep down inside, you're scared. But that's okay. In this talk at TEDxUCirvine, Leonard Kim shares the reasons you shouldn't run from your fears. Instead, you should use them to guide you.
2. Your body language may shape who you are | Amy Cuddy
You move around each day. Your body, whether you know it or not, is communicating a message to everyone you encounter, from your family, to your friends, colleagues and coworkers. It's also creating an image that is contributing to (or detracting from) your personal and professional brand. Instead of letting your natural body language define who you are, use Amy Cuddy's tips to redefine and take control of that image.
3. Borderline Millennial Disorder | Ryan Foland
You have probably seen studies and research that indicate social media is impeding your progress (and draining your time). But in Ryan Foland's talk, he provides three keys to using social media to accelerate, not hinder, your career.
4. Start with why | Simon Sinek
The "why" of your business or life is a powerful factor. For many, it is the driving force that propels their success, in both their personal and professional lives. By using Simon Sinek's method of starting with why, you can discover your own "why" and lay down a foundation that can influence the rest of your life.
5. The power of vulnerability | Brené Brown
This presentation is a personal favorite. When Brené Brown was first identified as a "storyteller," her ego wanted to get in her way. Her academic career made her want to be known as a researcher. Ultimately, however, she opened her perception to the bigger picture. In this talk, Brown covers the power of connection, shame, vulnerability and courage.
6. Teach girls bravery, not perfection | Reshma Saujani
Despite what the title may say, this talk is for both girls and boys. So many people are striving for perfection. Instead, they should cultivate the boldness to show off their work before it is perfected. In this talk, Reshma Saujani explains why we should be comfortable with imperfection. He advises listeners to be brave, not perfect.
7. Know your worth, and then ask for it | Casey Brown
We check our smartphones frequently, we set it down, and then we check one more time just to make sure we have no new messages. We know that we do this, and most of us do it often. But this behavior is causing problems that trickle through our entire society and culture. Daniel Midson Short reminds us to put our phones down and pay attention. His video explains why.
Each of these videos can make a direct impact on your life. I suggest you challenge yourself to watch one per day, for the next 10 days. Then take action, and share your results with others. This will raise the bar on your communication abilities as well.

Instructional Core practice _TAG_ How will we show we CARE?
As part of our school's Pre-Planning, I facilitated a faculty-teams workshop to continue our work and learning in the Instructional Core.
Here are my notes from the session.
The slide deck that accompanies this plan looks like this:
We watched 4:05 minutes of Practice is Everything to renew and review our norms around teaming.
How we practice, how we team, makes a difference. The words we choose and use when offering feedback contribute to how our learners author their identity. As we work to calibrate our expectations, we can also hone and enhance our ability to offer high-quality, positive, actionable feedback that empower learners to reach for their next independent level.
As seen in the slides, I used video timers to pace the teamwork time. What I learned is that the timers held me accountable for the work time promised to teachers. I was forced to wait, to be patient, and to not rush. So helpful to hold the time for our teachers.
When we focus on learning,
we hold time for learners.
And, just as we carefully plan and hold time for learning, we carefully choose what we notice and note. Words matter; the story you tell impacts how a learner is thought of and seen.
Amanda Thomas (_USER_) found and shared the video below. I used it in our session to illustrate the power of story.
As we begin a new school year with new learners, how will we seek a balanced story, describe what we want to see next, and balance our feedback to highlight success?
What story will we notice and note?
What feedback will we offer?
What will we contribute to how learners author their identity?
How will we show we C.A.R.E.?

UN/ISDR Calls for Increased Education on Disasters and Climate Change
19 December 2011: In acknowledgement of the impacts of Typhoon Sendong, which recently hit the south of the Philippines, Margareta Wahlström, UN Secretary-General's Special Representative on Disaster Risk Reduction and Chief of the UN International Strategy for Disaster Reduction (UN/ISDR), offered her sympathy to the people affected, and stressed there are lessons to be learned from the tropical storm.
In her message, Wahlström underscored the need for increased education on disasters and climate change, so that people understand the risk they expose themselves to when they refuse to heed evacuation warnings. Underscoring the need to improve the effectiveness of early warning systems, Wahlström noted that storm was identified two days before flash floods swept through Cagayan de Oro City and Illigan City.
Philippines Senator, Loren Legarda, and UN/ISDR Disaster Risk Reduction Champion for Asia, also called on local governments throughout the Philippines to "invest in flood infrastructure." [UN/ISDR Press Release][UN Press Release]

Incidence and location of positive nonsentinel lymph nodes in head and neck melanoma
Eur J Surg Oncol
BACKGROUND: The complex lymphatic drainage in the head and neck makes sentinel lymph node biopsy (SLNB) for melanomas in this region challenging. This study describes the incidence, and location of additional positive nonsentinel lymph nodes (NSLN) in patients with cutaneous head and neck melanoma following a positive SLNB. METHODS: A retrospective review was performed using a single institution prospective database. Patients with a primary melanoma in the head or neck with a positive cervical SLNB were identified. The lymphadenectomy specimen was divided intraoperatively into lymph node levels I-V, and NSLN status determined for each level. RESULTS: Of 387 patients with melanoma of the head and neck who underwent cervical SLNB, 54 had a positive SLN identified (14%). Thirty six patients (67%) underwent immediate completion lymph node dissection (CLND) of whom eight patients (22%) had a positive NSLN. The remaining 18 patients (33%) did not undergo CLND and were observed. Half of positive NSLNs (50%) were in the same lymph node level as the SLN and 33% were in an immediately adjacent level; only two patients were found to have NSLNs in non-adjacent levels. The only factor predictive of NSLN involvement was the size of the tumor deposit in the SLN>0.2 mm (p = 0.05). Superficial parotidectomy at CLND revealed metastatic melanoma only in patients with a positive parotid SLN. CONCLUSIONS: A positive NLSN was identified in 22% of patients undergoing CLND after a positive SLNB. The majority of positive NSLNs are found within or immediately adjacent to the nodal level containing the SLN.
