Women continue to be in the minority in school administration in public schools in the United States, although the majority of teachers are female. The role of assistant principal is the gateway to school administration. The purpose of this study was to describe the essence of the transition from teaching to school administration, the role of a female assistant principal, and the career aspirations of female assistant principals. This study used a phenomenological approach to understand the essence of the transition for the participants. Six women were interviewed using a semi-structured interview protocol to collect data on their experiences transitioning to the role of assistant principal. Using the process of horizonalization, the data were transcribed and analyzed using statements and quotes from the interviews to develop themes common to all participants. Findings revealed that these women continually seek to better themselves, others, and their organizations. They experienced a significant sense of loss as they transitioned to their new role. Lastly, the supports needed by women as they continue in their career as school administrators were uncovered.

Greece gifts new chances
Registrations are growing for the 'Second Chance Schools' initiative in Greece
The Second Chance Schools (SDE) initiative is an innovative lifelong learning programme from the Greek Ministry of Education supported by the ESF. Intended for individuals of 18 years and older who have only primary school leaving certificate levels of education, the project involves a public school that offers training to baccalaureate level to improve the employability and social inclusion of its graduates. Teaching covers many subjects, from languages and maths to computers and career counselling, and its approach is from the adult-learning perspective, focusing on active participation.


Theorem: The resolvent set is an open subset of \mathbb{C} on which the resolvent is an analytic operator valued function. Resolvents at different points commute and we have
 R λ(T)R μ(T)=(μλ)R μ(T)R λ(T) R_{\lambda}(T) - R_{\mu}(T) = (\mu - \lambda) R_{\mu}(T) R_{\lambda}(T)
The proof can be done as in the bounded case.
Commuting operators
The concept of commuting operators, which is of no problem in the bounded case, presents a conceptual difficulty in the unbounded one: for given operators AA, BB we would like to be able to say whether they commute, although their composite may not have dense domain. For selfadjoint operators there is a solution to this problem: We know that in the bounded case, two selfadjoint operators commute iff their spectral projections commute. This suggests the
 - Definition: two (possibly unbounded) selfadjoint operators commute iff all their spectral projections commute.
The spectral theorem shows that all bounded Borel functions of two commuting operators will also commute.
The following theorem states the reverse for two of the most important functions and shows that the definition of commutation above is reasonable:
 - Theorem: let AA and BB be selfadjoint operators on a Hilbert space \mathcal{H}. Then the following three statements are equivalent:
(a) AA and BB commute
(b) if Imλ\operatorname{Im} \lambda and Imμ\operatorname{Im} \mu are 0\neq 0, then R λ(A)R_{\lambda}(A) and R μ(B)R_{\mu}(B) commute, as it is defined for bounded operators: R λ(A)R μ(B)=R μ(B)R λ(A)R_{\lambda}(A) R_{\mu}(B) = R_{\mu}(B) R_{\lambda}(A)
(c) for all t,st, s \in \mathbb{R} we have exp(itA)exp(isB)=exp(isB)exp(itA)\exp(itA) \exp(isB) = \exp(isB) \exp(itA)
Strongly continuous one-parameter semigroups
A strongly continuous one-parameter semigroup is an unitary representation of \mathbb{R} on \mathcal{H} where \mathbb{R} is seen as a topological group with respect to multiplication, see topological group. An explicit definition recalling these concepts is this:
 - Definition: a function U:()U : \mathbb{R} \to \mathcal{B}(\mathcal{H}) is a one-parameter semigroup if the semigroup condition U(t+s)=U(t)U(s)U(t+s) = U(t)U(s) holds. If for every xx \in \mathcal{H} and tt 0t \to t_0 we have U(t)xU(t 0)xU(t)x \to U(t_0)x then it is strongly continuous. If every UU is an unitary operator, it is an unitary semigroup.
In the following a semigroup will be understood to be a one-parameter unitary strongly continuous semigroup.
In physics, one-parameter semigroups of this kind often represent the time evolution of a physical system described by an evolution equation.
 - Theorem: a selfadjoint operator AA generates a semigroup via U(t):=exp(itA)U(t) := \exp(itA)
 - Theorem (Stone's theorem): let UU be a semigroup, then there is a selfadjoint operator AA such that U(t)=exp(itA)U(t) = \exp(i t A). This operator is often called the infinitesimal generator of UU.
These two theorems are essential for the Schrödinger picture of quantum mechanics, which describes a system by the Schrödinger equation, we have now a one-to-one correspondence of selfadjoint operators which can be seen as Hamilton operators (only special operators will be seen as describing actual physical systems, of course), and semigroups which describe the time evolution generated by the Hamilton operator.
As a trivial observation we add that Stone's theorem is a (huge) generalization of the Taylor series, let f:f: \mathbb{R} \to \mathbb{R} that is (real) analytic in a neighborhood of 00, then we get for xx small enough:
f(h)= k=0 f n(0)n!h n=exp(ih(iddx)) f(h) = \sum_{k=0}^{\infty} \frac{f^{n}(0)}{n!} h^n = \exp(i h(-i \frac{d}{dx} ))
This shows that the operator iddx-i \frac{d}{dx} generates the semigroup of translations on the real line. Now we could, for example, use Stone's theorem to prove that iddx-i \frac{d}{dx} is selfadjoint by proving that the translation group is strongly continuous.
Subtleties resulting from domain issues
(This rather generic title will have to be revised.)
Nelson's example of noncommuting exponentials
Nelson's example shows that the rather involved definition of commutativity of two unbounded operators is well motivated, because a more naive one will have unwanted consequences. It is a counterexample to the following conjecture:
 - Conjecture (false!): Let AA and BB be selfadjoint operators on a Hilbert space \mathcal{H} and DD a dense subset such that both AA and BB restricted to DD are essentially selfadjoint. Suppose that for all xDx \in D we have ABxBAx=0 A B x - B A x = 0. Then AA and BB commute.
We have already seen that on 2\mathbb{R}^2 we can define two essentially selfadjoint operators i x-i \partial_x and i y-i \partial_y that generate translations along the x-axis and the y-axis respectively. Both the generated translations and the operators commute (the latter if applied to differentiable functions, of course).
The central idea of Nelson's counterexample is to replace 2\mathbb{R}^2 by a Riemann surface with two sheets, such that walking east, then walking north takes you to one sheet, while walking north then walking east takes you to the other sheet.
We use the Riemann surface MM of f(z)=(z)f(z) = \sqrt(z). We give a brief exposition of its construction: take two copies of \mathbb{C}, two "sheets", and call them I and II. Cut both sheets along (0,)(0, \infty), label the edge of the first quadrant along the cut as ++ and the edge of the fourth quadrant as -. Then attach the ++ edge of I with the - edge of II and the - of I with the ++ edge of II.
Let =L 2(M)\mathcal{H} = L^2(M) with respect to Lebesgue measure. As indicated above we define A = i x-i \partial_x and B = i y-i \partial_y, this is with respect to the canonical chart on each sheet that projects it onto \mathbb{C} and then identifies \mathbb{C} with 2\mathbb{R}^2.
Let DD be the set of all smooth functions with compact support not containing 00. Then:
(a) AA and BB are essentially selfadjoint on DD
(b) AA and BB map DD onto DD
(c) for all xDx \in D we have ABx=BAxA B x = B A x
(d) exp(itA)\exp(i t A) and exp(isB)\exp(i s B) do not commute.
Only part (a) needs further explanation…

Monthly utilities
just wondering how much do you guys pay a month for water and electricity? for single person and let's say during summer time with AC on half of the time
Both water and electricity are charged on a bimonthly basis. Water is cheap: around $200 every 2 months. Electricity can vary greatly between summer and winter due to the AC. In winter it's never more than $2000, where as the summer bill can push $3000.
2000 in winter and 3000 in summer those are every 2 months?
Yes, so it works out to be $1000 and $1500 per month in winter and summer, respectively.

Objectives Accurate and stable extrinsic parameter calibrations are the basis of fusing perception and positioning of cameras and light detection and ranging (LiDAR). To address the problems of the Dhall calibration method in constraint accuracy, stability, and convergence, this paper proposed a LiDAR and camera calibration method with joint point-line-plane constraints.
Methods First, line-line and plane-plane constraints were added, and the Kabsch method was used to obtain a closed-form solution, which reduced the influence of noise in the single corner constraint and improved the accuracy and stability of the calibration results. Then, multi-frame point clouds were superimposed to fit lines, and the fitting corners were averaged, which further reduced the influence of the point cloud noise, thus improving the convergence speed and stability of the calibration method.
Results Experimental results show that the proposed method can converge within 20 frames, and the reprojection error of the corner points was less than 2 cm.
Conclusions The proposed method has faster convergence speed and higher accuracy than the original method.

Psychology professor co-authors study on tennis grunting effectsUniversity of Hawaiʻi at Mānoa
Posted: Oct 1, 2010
You've heard them at tennis matches – a loud, emphatic grunt with each player's stroke. A University of Hawai'i at Mānoa researcher has studied the impact of these grunts and come up with some surprising findings.
Scott Sinnett, assistant psychology professor at the University of Hawai'i at Mānoa, has co-authored a study on the potential detrimental effect that noise has on shot perception during a tennis match.
Sinnett's work was published today in an online issue of Public Library of Science ONE. He co-authored the study with Alan Kingstone, psychology professor at the University of British Columbia, to determine if it is reasonable to conclude that a tennis grunt interferes with an opponent's performance.
As part of the study, thirty-three undergraduate students from the University of British Columbia viewed videos of a tennis player hitting a ball to either side of a tennis court; the shot either did or did not contain a brief sound that occurred at the same time as contact.
Participants were required to respond as quickly and accurately as possible, indicating the direction of the shot in each video clip on a keyboard. The extraneous sound resulted in significantly slower response times, and significantly more decision errors, confirming that both response time and accuracy are negatively affected.
"This is the first study to look at the issue of grunting in tennis. Our current work is also looking at how advanced and professional tennis players perform, to determine if they have developed any strategies to limit the negative effects of a grunting opponent," said Sinnett.
While these findings must still be validated on the tennis court, Sinnett and Kingstone noted that these consequences on faster tennis surfaces, such as the grass courts of Wimbledon or hard courts of the Australian and U.S. Open, are likely to be profound.

 sub getSurrounding {... }
 package main;
 use My::Map::Package;
This module implements the A* pathfinding algorithm. It acts as a base class from which a custom map object can be derived. It requires from the map object a subroutine named getSurrounding (described below) and provides to the object two routines called findPath and findPathIncr (also described below.) It should also be noted that AI::Pathfinding::AStar defines two other subs (calcF and calcG) which are used only by the findPath routines.
AI::Pathfinding::AStar requires that the map object define a routine named getSurrounding which accepts the starting and target node ids for which you are calculating the path. In return it should provide an array reference containing the following details about each of the immediately surrounding nodes:
Basically you should return an array reference like this: [ [$node1, $cost1, $h1], [$node2, $cost2, $h2], [...],...]; For more information on heuristics and the best ways to calculate them, visit the links listed in the SEE ALSO section below. For a very brief idea of how to write a getSurrounding routine, refer to the included tests.
As mentioned earlier, AI::Pathfinding::AStar provides two routines named findPath and findPathIncr. findPath requires as input the starting and target node identifiers. It is unimportant what format you choose for your node IDs. As long as they are unique, and can be distinguished by Perl's exists $hash{$nodeid}, then they will work. findPath then returns an array (or reference) of node identifiers representing the least expensive path to your target node. An empty array means that the target node is entirely unreacheable from the given source. findPathIncr on the other hand allows you to calculate a particularly long path in chunks. findPathIncr also takes the starting and target node identifiers but also accepts a state variable and a maxiumum number of nodes to calculate before returning. findPathIncr then returns a hash representing the current state that can then be passed back in for further processing later. The current path can be found in $state-{path}>.
This module requires Heap (specifically Heap::Binomial and Heap::Elem) to function.

Canaan Fir Plug Seedlings
[a.k.a. West Virginia Balsam Fir]
[Abies balsamea var phanerolepis]
You are here: Nurserymen > Evergreen Plug Seedlings > Canaan Fir Plug Seedlings
Canaan Fir plug seedlings are very similar to Balsam Fir plug seedlings and Fraser Fir plug seedlings in appearance, grow zones and other characteristics, making the Canaan a very desirable ornamental tree and Christmas tree. It stands out from the often troublesome Fraser in that the Canaan Fir can handle wetter soils and is less affected by root disease. This species is naturally Phytophthora resistant, whereas Fraser is not.
SOLD OUT till Fall 2021

Canaan Fir plug seedlings for sale, approx 5-10″ tall
Canaan Fir [and Balsam Fir] are an acceptable substitute for Fraser Fir in problematic environments such as poorly draining areas prone to phytophthora root rot. This species likes richer, darker soils with ample water.
The Canaan Fir is naturally found in isolated populations at higher elevations. This may be why Canaan Fir plug seedlings are slower to break bud than Fraser Fir plug seedlings or Balsam Fir plug seedlings, making it less prone to damage from a late frost. If you've been watching the weather since 2010, this alone is a valuable characteristic to have, since gorgeous trees damaged by frost freezes are not gorgeous trees. This species will reach heights of up to 50ft with a nice pyramidal shape under normal circumstances, and provides excellent privacy and wind protection due to its dense growth. The Canaan Fir is named for the Canaan Valley in West Virginia. It is an excellent alternative to Balsam Fir and Fraser Fir in most situations.
Canaan Fir plug seedlings: characteristics and info
- prefers hardiness zones 3-7
- does ok in full sun but prefers partial shade
- mature height and spread: up to 50 ft high, 15-20 ft spread
- prefers dark rich soils, swampy soils, wet loamy soils, low areas and around ponds and streams

Pleistocene Park and the North-East Scientific Station
The North-East Scientific Station (NESS) and Pleistocene Park are scientific organizations located in the north of Siberia, 5 km from the town of Chersky (Yakutia)
(68° 44'N, 161° 23'E).
Established in 1977, the North-East Scientific Station has become one of the world's largest Arctic research stations, providing varied opportunities for study throughout the year in various disciplines such as ecology, climate change, arctic biology, permafrost studies, hydrology, limnology, geophysics, atmospheric physics, and others. NESS has 3 laboratories with modern equipment and the ability to welcome up to 50 researchers at a time.
Pleistocene Park is a major initiative that includes an attempt to restore the mammoth steppe ecosystem, which was dominant in the Arctic in the late Pleistocene. The initiative requires replacement of the current unproductive northern ecosystems by highly productive pastures which have both a high animal density and a high rate of biocycling.
Experiments with animal reintroductions were begun in 1988. Currently, Pleistocene Park consists of an enclosed area of 16 square kilometers that is home to 5 major herbivore species: bison, musk ox, moose, horses and reindeer.
May 1, 2012 — New photos of the park from 2011-2012
April 24, 2011 — Wapiti and Bisons have arrived to the Park
Six Wapiti and five Bisons have arrived to the Park. All feeling fine. More information and photos are coming soon.
March 17, 2011 — New photos of musk ox
Ice on the river is now deep enough, so we have made 45km of winter road to the Park and now it is much easier to get there. Took camera with me and now we have a few new shots.

In-situ investigation of discolouration processes between historic oil paint pigments
- Publication Type:
- Journal Article
- Microchimica Acta, 2006, 155 (1-2), pp. 319 - 322
- Issue Date:
Discolouring interactions between paint pigments have been observed since the mid 19th century. The source of some of these discolourations is the production of copper sulfides from an interaction between cadmium sulfide pigments and copper containing pigments. In this work, the discolouring interaction between cadmium yellow and malachite pigments was observed dynamically using the environmental scanning electron microscope (ESEM).

This model demonstrates the use of GoldSim's optimization feature to calibrate a snowmelt model by automatically adjusting parameters to achieve correlation between historic streamflow record and streamflow calculated in the model. The historic record used to drive the snowmelt model includes temperature and precipitation. Calibration accuracy is measured using an R2 factor. Five model parameters are used as optimization variables and the objective function is to maximize the R^2 factor, which is documented in the model. An R^2 value of 1.0 indicates perfect calibration.
The optimization parameters include recession constants (x, y), and the degree-day factor (a).
The snowmelt-runoff model (SRM) is known to provide support for reservoir operators and water supply managers in anticipating and acting on changes in snowmelt runoff. WinSRM can be used for predicting snowmelt runoff which can then be incorporated into a reservoir model to estimate fill targets for the early summer months and often provides decision makers with increased knowledge for their annual strategic planning. To further understand their risks, modelers can use model results from SRM and statistically analyze them to quantify risks probabilistically. Refer to the Snowmelt-Runoff Model User's Manual for more information about the SRM model.

When a service doesn't run as you would like, when you want to change its default configuration, Systemd offers you several options.
Firstly, you can copy the standard unit file from the /usr/lib/systemd/system directory into the /etc/systemd/system directory and then changes its content. The new unit file will take precedence over the default one. Don't forget to run the systemctl daemon-reload command each time you create or modify a unit file
Also, if you want to make clear that you built the new unit file from the default one, you can add the following line at the beginning of the new unit file (here /etc/systemd/system/httpd.service):
.include /usr/lib/systemd/system/httpd.service [Service] CPUShares=500
Here you can read.include. It's not a typo but the syntax required by Systemd.
The specified directive (here CPUShares) will override the previous configuration except if this directive allows multiple values, in this case, the new value will be added at the end. To avoid this situation, you will have to proceed in two steps: assign an empty value and then assign the desired value in another line.
Secondly, instead of copying the default unit file, you can create a directory of the same name with the.d suffix in the /etc/systemd/system directory and drop a file with the.conf suffix containing the settings you want to override. This is automatically done when using the systemctl set-property command. This method also allows to override settings coming from a unit file located in the /etc/systemd/system directory.
In our example, create the /etc/systemd/system/httpd.service.d directory, then the file called constraints.conf and paste the following lines into it:
Thirdly, it is still possible to customize the environment before the service starts. You can specify a list of environment variables and their values with the Environment directive:
Environment="VAR1=word1 word2" VAR2=word3
You can also use a dedicated file with the EnvironmentFile directive. In the httpd case, you can see the following line in the /usr/lib/systemd/system/httpd.service file:
Finally, don't hesitate to run the systemd-delta command to know what was changed from the default configuration.
Who said that Systemd was not flexible!

How to make double hung windows using old materials
Use of double hung windows in homes is quite old and still there are large numbers of people who prefer them for their homes. The leading benefit of these windows is that they are suitable for almost every home. Generally, when it is the matter of double hung windows, people prefer to design their own windows with their own efforts. People prefer to design double hung windows by own efforts mainly because of the reason that they will get what exactly they want. Any material that suits the windows can be used for this tasks but majority of time people prefer old materials for designing the double hung windows.
There is lot of things that one has to keep in the mind before designing the double hung window through old materials. It is necessary to consider influences on a design before starting any work. Also it is better to have a look at the features of the design.
1. Selection of materials
When it is the matter of choosing old materials, there are large number of options that are easily available. Selection of materials depends upon on lot of things and especially on the type of weather on the place where these windows are to be installed.
2. Designing the double hung windows using wood
Wood is one of the better options for designing such windows. Generally, wood is one of the oldest materials available for this and is preferred for this task mainly because of its durability. For designing the double hung windows through wood, what one has to do is:
- Firstly, select the design and size of the window to be designed.
- Next step is to cut the wood as per the design. Cutting tasks include cutting of wood in different shapes and sizes so better is cut them with full concentration. For this, some of the tools are needed which can be taken on rent. Use of red cedar wood is a great option.
- Wooden parts can be joined using iron sticks.
- Paint the windows once they are installed because painting them before installation may destroy the paint during installation.
- Selection of glass is not a big task and majority of times a plain glass is used.
It must always be remembered that wood is not suitable for all weather conditions. Wood is a better option for places have less annual rainfall in a year.
3. Using iron for designing double hung windows
The use of iron for designing double hung window is quite common just like wood. The iron has its own merits and demerits over wood. The designing procedure of these windows through iron is same as design of windows through wood but there is one major issue with iron and that is cutting and designing of iron is quite hard and for this sometime complex tools are required. It is because of this reason, people do not prefer DIY task for designing double hung window through iron. Generally, iron double hung windows are suitable for majority of weather conditions.
4. Plastic is another wise choice
Just like iron and wood, plastic is another one of the oldest materials that is preferred by large number of people for designing double hung window in their own way. The leading advantage of plastic is that it is suitable for any design any size. Another advantage of plastic is its low cost and long life. Plastic has one leading disadvantage and that is it loses its grace, when come under direct sunlight and thus not suitable for places having dry atmosphere.
Some important things to be kept in mind while using plastic are:
- This material needs perfect cutting and a small variation in size may result in failure of entire design.
- Joining the plastic needs lot of care and thus task is performed by a burning process.
5. Installation of double hung windows
There are generally two sashes that one has to implement while designing the double hung windows. One sash is at the top of window while other at the bottom. Both of them are movable. Balancing devices are used for shifting the sashes up and down and they also support their movement as well. The overall weight of sash is balanced by overall weight of balancing devices thus windows can easily be set at any position.
Double hung windows can easily be designed using old materials and by preferring old materials one can have lot of benefits including cost saving and especially one can get the desired design for his/her double hung windows. Use of double hung windows designed with old materials has become a modern trend nowadays.

Data collection at Hunter Water condition assessment sites and initial model calibration
The aim of Activity 3 is to develop models for the description and prediction of the long-term corrosion losses and maximum pit depths of cast iron (and also steel) pipes buried in soil. The approach currently being pursued is to develop a corrosion model based on corrosion fundamentals and on documented field observations. The models will describe the amount of corrosion as a function of exposure period and the main influencing external soil conditions. Field data has recently been collected at a number of condition assessment sites within Hunter Water Corporation's network, and this data was used to calibrate an initial model for pipes buried in clay soils. A summary of this work is presented in this fact sheet. More details on this work are presented in Petersen et al (2013).

Background: Students may become less adept at developing strong patientphysician relationships during medical school. We evaluated whether students choosing careers in surgery show a similar negative trend. Methods: Scores from 2 validated measurements of medical personality were compared using repeated-measures analysis of variance. The Patient Provider Orientation Scale (PPOS) assesses whether students are more patient-centered or paternalistic, and the Physician Reaction to Uncertainty Scale (PRUS) measures willingness to disclose uncertainty. Results: From 1998 to 2005, 236 students completed the PPOS and PRUS in the first and third year of medical school. Surgical students remained patient-centered in their first and third year of medical school (mean PPOS, 4.5 vs 4.54, respectively; P <.348). In addition, they became more willing to disclose uncertainty (mean PRUS improved from 25.5 to 23.8; P <.002). Conclusions: Students choosing careers in surgery maintain or improve upon personality traits that are important for developing strong patientphysician relationships. All rights reserved.

Ensuring Connectivity via Data Plane Mechanisms
 - Junda Liu
10th USENIX Symposium on Networked Systems Design and Implementation (2013)
We typically think of network architectures as having two basic components: a data plane responsible for forwarding packets at line-speed, and a control plane that instantiates the forwarding state the data plane needs. With this separation of concerns, ensuring connectivity is the responsibility of the control plane. However, the control plane typically operates at timescales several orders of magnitude slower than the data plane, which means that failure recovery will always be slow compared to dataplane forwarding rates.
In this paper we propose moving the responsibility for connectivity to the data plane. Our design, called Data-Driven Connectivity (DDC) ensures routing connectivity via data plane mechanisms. We believe this new separation of concerns basic connectivity on the data plane, optimal paths on the control plane will allow networks to provide a much higher degree of availability, while still providing flexible routing control.

National Cancer Survivors Day 2021:10 Hopeful Quotes To Inspire Cancer Survivors and Fighters
Cancer is the leading cause of death worldwide. According to WHO, over 45% of people around the world were estimated to be affected by this disease between 2008-2030. It was also projected that 10 and 11 million cancers will be diagnosed each year in lowand middle-income countries by 2030. Right now, there are millions of people worldwide fighting this insidious disease. We know cancer isn't all rainbows and sunshine and keeping a positive outlook during this time can be quite difficult. But sometimes messages of hope can always inspire strength.
Many cancer patients hold on to optimistic messages that promise good times hard and helps them to get through each day with the promise of hope on the horizon. Here are few quotes that we hope might inspire every cancer survivor and fighter to hold on and fight the good fight.

Education Secretary John Swinney says the Scottish Government are considering a'staggered' approach to allowing students to return home for Christmas.
It comes as students from Edinburgh University held a protest yesterday over the'mistreatment' they have faced over being forced to self-isolate in halls and given "false promises of hybrid learning."
John Swinney said that the Scottish Government is "learning lessons" from the Covid outbreaks sparked by the return of students and that will help them decide how they return at Christmas.
The Education Secretary is now holding talks with other UK nations to discuss what approach they can take to stop another sudden spike in Covid-19 cases.
The Education Secretary with Nicola Sturgeon
Speaking on the issue, he told the BBC's Politics Scotland programme: "Some of the points that we're looking at are around staggered returns of students so that they don't all come back in one go, that we look at arrangements for how testing can be part of the architecture of how we handle that return.
"What we expect of students when they are returning home and when they're coming back into universities and how they will spend their time, how their learning will be undertaken - these are all issues that are being explored."
The Scottish Government is now considering a system of mass testing which would be supported by a staggered return of students to stop the testing system getting overwhelmed.
He added: "These are some of the options that are being looked at and obviously... the practicalities of that are changed and eased if the return of students is staggered over a longer period."


Illustration for article titled How to Find a Stud Without a Stud Finder
We've all been there at some point: anxiously trying to find a wall stud while you're in the process of hanging a picture, shelf or TV mount. Most stud finders are inconsistent at best, and I've found the more I learn about how houses are built, the easier it is to find a stud through logic instead of equipment. In lieu of buying yet another tool, here are a few tips for finding a stud without any fancy equipment.
1. Understand wall construction
Photo: Construction Projects ( (Flickr)
Every house is different, but there are a few things you can count on. More modern stick-framed houses (anything built after 1920 or so) is likely built with 2×4 or 2×6 studs. Here are some things you should know about how walls are framed.
 - Studs are generally spaced between 16″- 24″ on center (which means from the middle of one stud, to the middle of one next to it.) 16″ is the most common dimension though.
 - You will also find studs on either side of a window or door, but their placement is determined by the floor plans so they won't typically have the 16″ spacing
 - Most electrical boxes (switches or outlets) are attached to a stud on one side.
 - The actual dimensions of a 2×4 lumber vary based on the date the house (or the particular wall of the house in question) was built. For example, between _PHONE_ rough cut 2×4's were most common and were actually 2″ by 4″, for the most part. Houses built between _PHONE_ might have 2x4s that are 1-⅝" by 3-⅝", more modern 2x4s are actually 1-½ by 3-½ (all of which matters if you're trying to measure from the center of one stud to the next.)
 - Trim (crown molding, baseboard, and shoe molding) is generally nailed to a stud.
2. Look at the trim
Since the baseboard should be attached to the studs, look to see if you can spot where it might have been nailed. These holes—dimples—are generally filled with caulk and painted, but you may be able to spot one to identify the location of a stud. If you find one, try measuring in 16″ increments to locate the additional studs.
3. Use the switch
Photo: Rebecca Landis ( (Flickr)
If you don't have any luck checking out the trim, look for switches or outlets, knowing that at least one side of an electrical box will be mounted on a stud. Personally I'm not great at doing the "knock test" on the wall, but I can usually detect from tapping which side of the outlet is attached to the stud. Then you can measure about 3/4″ away from the outlet on the stud side and use that as the starting point to determine the 16″ intervals.
4. Measure from the corner
Photo: garann ( (Flickr)
With studs generally 16″ on center, you can also do calculations from a corner of the room. This method can be a little iffy, because all rooms aren't built in numbers divisible by 16″ so you are likely to have a stud that is less than 16″ from one corner. Try the "knock test" near the corner to see if you can determine where the shorter stud-spacing might have been added. This only really works if you're measuring a corner off the exterior of the house, but there may be a situation where this helps (and it's certainly better than blindly drilling a dozen holes in your wall, hoping to hit a stud.)
Also, one of the very best ideas I had when building the addition on my last house was to take pictures of every wall in every room after they were framed in but before we hung the drywall. Those reference photos came in handy more times than I can count after the drywall was up.

Ear piercing in infants has been a cultural practice for centuries, with proponents and opponents expressing varying views on its appropriateness. The decision to pierce a baby's ears is deeply personal and often influenced by cultural, religious, and familial factors. Let's explore the different perspectives on piercing babies' ears. Providing a well-rounded understanding of the debate and the ethics of baby ear piercing.
Cultural and Familial Traditions:
Many families view ear piercing as a cultural or familial tradition, often passed down through generations. In some cultures, piercing a baby's ears is seen as a rite of passage or a symbol of cultural identity. Families that hold these beliefs may choose to pierce their infants' ears shortly after birth as a way of honouring their heritage. Other cultures wait until much later as having your ears pierced is considered a more adult thing. In the UK, many parents will take their children to get pierced at the end of year 6.
Respect for cultural diversity and sensitivity to cultural practices are important considerations in discussions about baby ear piercing. For many communities, ear piercing holds cultural significance and is deeply ingrained in traditions and customs. Criticising or condemning these practices without understanding their cultural context can be perceived as ethnocentric or culturally insensitive.
Religious beliefs can significantly impact the decision to pierce a baby's ears. Some religious traditions have specific rituals or ceremonies associated with ear piercing. Others may discourage or prohibit the practice altogether. Families often consult religious leaders and adhere to specific guidelines within their faith when deciding whether or not to pierce their baby's ears. When we have a family that comes as part of their religious beliefs, we need be informed ahead of time. We can then then comply on the piercing day with the correct ear piercing process.
Ethical Concerns of Baby Ear Piercing:
On the opposing side of the debate, there are medical and ethical concerns associated with piercing infants' ears. Critics argue that subjecting a baby to the pain and potential risks of infection is unnecessary. We practice painless ear piercing in our clinic.
Infants may not have the ability to consent to the procedure, raising ethical questions about bodily autonomy. Some healthcare professionals recommend waiting until a child is old enough to express their own desire for ear piercing. Allowing them to participate in the decision-making process.
We are of the opinion that once a child is old enough to communicate their feelings, they need to be prioritised in the decision making process. You can read our negative reviews that we "don't know what we're doing" because we have shown parents the door when the child made it clear they didn't want to have their ears pierced. We are ok with that, in fact, proud!
Parental Autonomy vs. Child Autonomy:
One of the central ethical dilemmas surrounding baby ear piercing is the tension between parental autonomy and child autonomy. Parents have the legal authority to make decisions on behalf of their children, including decisions about their appearance. However, some argue that children should have the right to bodily autonomy and self-determination, which includes the right to decide whether or not to undergo cosmetic procedures like ear piercing.
Waiting until the child is old enough to consent:
Whilst this sounds like a good idea on the surface, we also need to be aware of the downside of leaving it until the child is older. We see children with a huge amount of anxiety coming in for ear piercing. This anxiety primarily comes from her school friends telling her how "painful" it was, how they "nearly died" from the pain and could not "sleep for days" post the piercing. By the time they get to Lorena they're are an axious mess. They don't believe when she promises that it will be pain free and the next hour is full of dread and anxiety. Not to mention the emotional build up the day.
Also, we need to consider that the older the child gets the higher the chances of complications such as infections. Parent's tend to be under the impression that an older child can look after their piercing. Please consider the general state of the average 13 year old's bedroom before placing this responsibility on their child. Lorena is passionate about this point and she equates it to a parent finally allowing a child to have a pet but only if she agrees to do 100% of the care of that pet. In other words, setting up the child to fail…because…she's…a child…unable to keep her promise.
Teens face a different type of problem. Having waited so long to have their ears pierced they want to change their earrings as soon as possible. Ensuring an infection to the area. Sometimes they will exchange earrings with their friends at school straight from one ear to the other. Every single time that we have had a complication with one of our piercings (because we want to know immediately and see you if something goes wrong regardless of how much time has passed) the child has walked in with a different, and/or dirty earring on.
Practical and Medical Considerations of the ethics of Baby Ear Piercing:
Practical considerations, such as hygiene and aftercare, also play a role in the debate. Infants require meticulous care to prevent infection, and parents must commit to cleaning the pierced ears regularly.
Additionally, concerns about potential allergic reactions to certain metals used in earrings may influence the decision-making process. What we do know is that infections among infants are rare whilst on older children the infection rate is as much as 50%. This is because parents do the aftercare rather than leave it to an older child. Also, infants tend to not play with their ears therefore keeping bacteria at bay.
In case of infections, antibiotics is the only way to fight the infection. The ear is an area of the body that doesn't fight off infection on it's own so a prescription from your doctor is the only way to fight it.
The Importance of Informed Consent:
One common thread in the discussion is the importance of informed consent. Regardless of cultural, religious, or familial traditions, advocates for waiting until a child can express their own wishes argue that individual autonomy should be respected.
Allowing the child to participate in the decision-making process when they are older may foster a sense of ownership over their body. Cultures that pierce as an infant argue that it's only one of many decisions that the parents make for this children. Doing it young has huge benefits with future possible complications. We have made the decision to not pierce a child that says NO or shows signs of fear.
Making the decision to pierce your baby or not:
The debate surrounding ear piercing in infants is nuanced and multi-faceted. Cultural, religious, and familial traditions often clash with medical and ethical considerations. Ultimately, the decision to pierce a baby's ears is a personal one that falls on the parent. It should be made with careful thought and consideration of the child's well-being. As societal perspectives evolve, conversations around informed consent and bodily autonomy will likely continue to shape the way we approach this age-old practice. Ultimately, this is a personal decision made by the child's family. Along with the piercer's responsibility to have the child's best interest at heart. Sadly, we have seen in our practice that some parents have other priorities above their child's.
We take ear piercing very seriously. We use numbing cream to make the child have a pain free procedure that both parents and child can enjoy. You can call us on 0800 _PHONE_ and you can book online HERE. You can book a free video consultation if you wish to speak to Lorena directly.

Sun GlassFish Enterprise Server v2.1.1 Deployment Planning Guide
Estimating Bandwidth Requirements
To decide on the desired size and bandwidth of the network, first determine the network traffic and identify its peak. Check if there is a particular hour, day of the week, or day of the month when overall volume peaks, and then determine the duration of that peak.
During peak load times, the number of packets in the network is at its highest level. In general, if you design for peak load, scale your system with the goal of handling 100 percent of peak volume. Bear in mind, however, that any network behaves unpredictably and that despite your scaling efforts, it might not always be able handle 100 percent of peak volume.
For example, assume that at peak load, five percent of users occasionally do not have immediate network access when accessing applications deployed on Enterprise Server. Of that five percent, estimate how many users retry access after the first attempt. Again, not all of those users might get through, and of that unsuccessful portion, another percentage will retry. As a result, the peak appears longer because peak use is spread out over time as users continue to attempt access.


I would like to control my dc motor using the Arduino Uno WiFi Rev2 using an html range slider. Now I can control the motors speed and direction using push buttons just fine. My code is posted below of what I've done so far.
client.println(".class-name{writing-mode: bt-lr; webkit-appearance: slider-vertical;width: 8px;height: 175px;padding: 0 5px;}");
client.println("");
This code below is the current button code. I need the below code to be used by the slider code above:
if (currentLine.endsWith("GET /MONFWD")) {
digitalWrite(MOTOR_A_ONE, HIGH); // Establishes forward direction of Channel A
delay(1000); // DELAY BEFORE RELEASING BRAKE
digitalWrite(MOTOR_A_TWO, LOW); // Disengage the Brake for Channel A
analogWrite(MOTOR_A_ENGAGE, 255); // Spins the motor forward on Channel A at full speed
 - 1
 And what is your question? You didn't ask one. Please describe, what exactly your problem is in writing the needed code. – chrisl Oct 18 '19 at 1:05
Here's an example of slider that changes a Servo speed, In html page code you have to add this:

 Value:
var slider = document.getElementById("myRange");
var output = document.getElementById("demo");
output.innerHTML = slider.value;
slider.onchange = function() {
 output.innerHTML = this.value;
function pwm_change(val) {
 var xhttp = new XMLHttpRequest();
 xhttp.open("GET", "setPWM?PWMval="+val, true);
In arduino you have to define handler like this:
void handle_pwm() {
 String pwm_val = server.arg("PWMval"); // reading from slider on html pagae
 Serial.print("slider val: ");
int pwm_value = map(pwm_val.toInt(), 0, 1023, 0, 180);
server.send(200,"text/plane","0"); // handling the webpage update
And define servo and handler in Setup() section:
void setup(void){
server.on("/setPWM", handle_pwm);
 - I'm not using the servo.h library...I'm using a motor shield which already works with the push buttons....if I ignore the servo.write and servo.attach arguments the code should work fine correct? – PilotinControl Oct 18 '19 at 18:14
 - Also the above code is not compatible with the Arduino Uno WiFi Rev 2. It does not use server.on or server.arg – PilotinControl Oct 18 '19 at 20:44
 - no difference, you can follow the above example for both motor shield and Uno WIFI board, just replace servo.write() command with motor.setSpeed() for changing DC motor's speed in motor shield.just need to map slider value (0-1023) to your motor speed range,that is usually (0-255). And by using libraries like WiFiNINA, you can have server.xyz arguments for Uno Wifi board so. – M sayeh Oct 18 '19 at 21:46
 - I am using the WiFiNINA library and there are no equivalents for server.arg and server.on except for client.read and client.println. Also no matter where I put the function handle_pwm it throws errors. The slider works fine as I did change the values there. Its getting the function to line up with the slider that its not working. I currently have 3 push buttons that work. Motor FWD, MotorREV and MotorBrake those work fine. I just need a slider to control the motor speed smoothly – PilotinControl Oct 18 '19 at 23:04
 - the above example is originally written for Nodemcu board,It enjoys much easier libraries to parse http requests,like ESP8266 WebServer lib including server.arg command and etc... for Arduino Uno WiFi Rev 2,it is not seemingly as various as nodemcu,so,you should deal with the http requests with commands like client.read(), currentLine.endsWith() and equivalents like this. – M sayeh Oct 19 '19 at 0:00

I'm having problems with the last two lines in Listing 1. As they stand, they work fine. But when I preface fil.DateCreated and fil.DateLastModified with text in the code
WScript.Echo("File created on " _
 + fil.DateCreated)
WScript.Echo("File last" & _
 "modified on " + _
I receive the error message C:\Scripts\files.vbs(11, 1) Microsoft VBScript runtime error: Type mismatch: '\[string: "File created on "\]'. I can't figure out why. Can you help?
The error you're seeing is the result of using the wrong operator to concatenate different VBScript subtypes. VBScript's string concatenation operator is the ampersand (&), not the addition (+) operator.
What's interesting about your example is that the addition operator works in the first two WScript.Echo statements but not the second two statements. Here's why. The fil.Path and fil.Name variables and the text that prefaces fil.Path and fil.Name are all String subtypes. In these two statements, VBScript can concatenate the strings because all the pieces are of the String subtype.
However, when you preface the fil.DateCreated and fil.DateLastModified variables with text, you're trying to concatenate String subtypes with Date subtypes. When the VBScript interpreter sees the addition operator, it converts the Date subtype to an Integer subtype then attempts to add the integer to the string. The result is a type mismatch because you can't add a number to a string. Replacing the addition operator with the concatenation operator causes VBScript to convert the Date subtype to a String subtype. VBScript can then glue the substrings together. So if you change the addition operators to concatenation operators, you can successfully add text to the last two statements in your script. (For more information about VBScript operators, see Dino Esposito, "Understanding VBScript: Operators," August 1999.)
I'm designing a Windows NT 4.0 rollout for a company that wants to deploy a standard image to 130 desktops. This deployment must be hands-off. The company currently has IBM's LANClient Control Manager (LCCM) and Wake-on-LAN managed PCs that I can use to multicast the NT 4.0 image to the desktop. However, how do I automate changing the computer name and joining the workstation to the domain after the new image boots?
You can use Windows Script Host (WSH) 2.0 and Active Directory Service Interfaces (ADSI) 2.5 to automate changing the computer name and joining the domain. WSH and ADSI must be part of your standard NT 4.0 image. Here's how you accomplish these two tasks:
1. Changing the computer name. Automating the process of changing the computer name is simple. You just need to use the WSH Shell object's RegWrite method to change a few Registry values and reboot. Specifically, you need to modify the NetBIOS and TCP/IP Hostname Registry values with code similar to that in Listing 2. (This script doesn't include error-checking code.) As Listing 2 shows, you begin by declaring the variables. You then specify the paths to the Registry values you want to change. Finally, you specify the new computer name and use the RegWrite method to make the Registry changes. After you run this script, you must reboot the workstation to commit the changes. (For more information about how to use the RegWrite method, go to You can also download the executable Windows Script Host Reference at Install the documentation by running wshdoc.exe after the download is complete.)
To use this script, you need to change w-bobwells to your new computer name. Therein lies the only challenge you might face with this automation task: obtaining the new computer name. Solutions I've seen include setting the computer name to the machine's primary media access control (MAC) address or retrieving the new computer name from a local or remote configuration file.
2. Joining the domain. You can use ADSI 2.5 to create the new computer account and set the initial computer account password. The example script in Listing 3 demonstrates the process for a workstation named Hercules in the domain Olympus.
You begin this script by creating a reference to ADSI's WinNT: provider, which is the mechanism that ADSI uses to access and manage NT 4.0 and 3.51. Next, you call the OpenDSObject method to authenticate and bind to the container that will hold the new computer account object. OpenDSObject takes four parameters:
 - The ADsPath to the target ADSI object. In this example, you're binding to the Olympus domain.
 - The account credentials to authenticate the bind request.
 - The password for the account credentials.
 - The type of authentication to perform the bind operation. The value 1 is the authentication flag that enforces secure authentication.
After you successfully bind to the target domain container, you use the IADsContainer::Create method to create the computer account object. This method takes two parameters: the type of object to create and the object's name. In this case, you're creating a Computer object named Hercules. On completion, the Create method returns a reference to the new object. Although you might think that the computer account exists at this point, it doesn't exist until you use the SetInfo method. SetInfo writes the object to the underlying directory. The last two lines set the computer account's initial password.
To use this script, you need to change several values to match your environment:
 - Change "Olympus" to the name of the domain that will contain the new computer account.
 - Change "Administrator" to the name of a user account that has sufficient domain privileges to create computer accounts.
 - Change "Password" to the previous user account's password.

- Health Sector
- New Zealand
Counties Manukau in South Auckland is the fastest growing district in New Zealand. It is multi-ethnic, but minorities are severely under-represented in the health workforce.
- to create a seamless school to employment pipeline that supports and develops local talent
- to double the number of Maori and Pasifika people working within the organisation, across all health professions
- to create a workforce that better reflects the diversity of the communities they serve
Counties Manukau Health (CM Health) partnered with local schools, identified by expression of interest, to become Health and Science Academies (HSAs). The HSA program is designed around supporting students to gain direct entry into tertiary level sciences, through extra tuition in science, maths and English, and other activities, including hospital visits, panel sessions with health professionals and academic mentoring.
- CM Health has embarked on a number of equal opportunity initiatives to complement the HSAs.
- All Maori and Pasifika candidates are short-listed for priority workforces.
- A senior Maori or Pasifika representative is always included in interview panels for priority workforces.
- Workforce recruitment targets are set to ensure that the diversity of the workforce reflects the diversity of the local population by 2025.
- Initially three schools were selected to become HSAs.
- Initial funding to implement the HSAs was provided by a partnership with the Tindall foundation, a charitable foundation that operates across New Zealand. In 2016, CM Health agreed to fund the three colleges directly.
- A Grow Our Own Workforce Governance Group meets up to four times a year to provide strategic guidance and monitor the ongoing implementation of the academies.
- An operational leadership group was established between CM Health and the Principals of each of the colleges to improve collaboration and share best practice.
Program design strategies
- The academies support Maori and Pasifika students with an interest in, and aptitude for, careers in health. Selection is made on students evidencing commitment, alongside some academic ability.
- The HSA program is a joint endeavour between families, community and teachers and regular parent information events are held.
- To profile the wide range of possible health careers, CM Health provides events, hospital visits and talks with health professionals. The provision of hands-on experiences of health sector jobs, and opportunities to talk to Maori and Pasifika health professionals, helps to increase student motivation and sense of purpose.
- The HSA program is designed to support students to gain direct entry into tertiary level sciences. Compared to mainstream students in Year 11, who have five lessons of science in a six-day timetable, students in the HSAs have ten lessons.
- The program is recognised as a long-term strategy. Once the students transition into tertiary study, depending on their area of studies, they won't be ready for employment for a minimum of three years after that.
- Above-average school attendance rates are being maintained by Academy students.
- One of the students in the first cohort was inspired to study nursing and is now employed in CM Health. She is the first in her family to be university educated, and her story has been featured on local news networks in Auckland.
- The Pasifika workforce has increased from 9% to 11% since 2010.
- The Maori workforce has increased from 5% to 8% since 2010.
- It is essential to involve Maori and Pasifika leadership when designing and implementing Maori and Pasifika health workforce development programs.
- Ensure a clear vision and purpose.
- Ensure joint strategic and operational planning at the right level with a well-structured workforce plan.
- Occasionally family-support can turn into family-pressure when students are expected to pursue a career to which they do not have initial inclination.
- The innovations being generated by the Academies draw strongly on the advantages of being a small and focused learning community within the school.
- Students need to be able to see a workplace, and be able to actively imagine themselves doing the role.
- Without surrounding attention and encouragement from families and teachers, books and resources are not helpful on their own.
- have local schools with the capability and capacity to offer health science subject education?
- have access to transport for students?
- have culturally-appropriate and safe mentoring and tuition?
- have organisational understanding of and support for the importance of a culturally diverse workforce?
- have Equal Employment Opportunity (EEO) programs that support nondiscriminatory employment practices?
- meet the specific cohort's training needs?
- champion and facilitate the program?
- provide culturally-appropriate and safe development opportunities and methods?
- offer extra tuition and mentoring?
CONSIDERATIONS FOR PROGRAM SCALING
- have realistic job opportunities and student numbers required to meet this?
- have the required financial and personnel resources?
- have sufficient interested student numbers?
- have host organisations, teachers and trainers who are supportive of diversity and can provide culturally-appropriate and safe environments?
- have sufficient placement and development opportunities?
- you don't have an organisational culture and practices that support diversity?
- the newly-qualified workforce seeks opportunities elsewhere (out of region or even country)?
- you aren't prepared for the length of time required to develop trainees to competence and fill roles?
- there are changes to funding or policy priorities?


German Lessons
Get Off On the Right Foot
English has quite a few idioms using the word "foot," and the German language also "puts its best foot forward" in this regard!
Some German foot expressions are very similar to English:
Ich nehm' mein Herz und leg's dir zu Füßen.
I'll take my heart and lay it at your feet.
Caption 3, Deutsche Musik - Chris und Croissant
 Play Caption
Sometimes, a German expression is close to English, but with a spin of its own:
Er war von Kopf bis Fuß grün angezogen.
He was dressed in green from head to foot [idiom: completely].
Caption 23, Märchen - Sagenhaft - Ein Topf voll Gold
 Play Caption
The above expression is very similar, of course, to the English "from head to toe." Most German idiomatic expressions with the word Fuß are quite different, however:
Und die Besucher müssen wirklich gut zu Fuß sein.
And the visitors must be really good to foot [idiom: agile].
Captions 18-19, Internationale Automobilausstellung - IAA in Frankfurt öffnet die Pforten
 Play Caption
The English foot idiom that comes closest is "light on their feet." At Yabla, we translate idioms literally (word for word), and then add a dictionary-style definition for clarity.
Be careful you don't "put your foot in it" though, as some expressions sound similar to English, but have a completely different meaning:
Was Henne gesagt hat, hat ja eigentlich auch Hand und Fuß.
But I think what Henne has said also actually has a hand and a foot [idiom: makes sense].
Caption 48, Luxuslärm - Interview
 Play Caption
If you recall the English saying "to wait on someone hand and foot," you might falsely interpret the German to mean that Henne was being servile, when in fact she was making sense!

What is the difference between object and class in Scala?
Marcin Krykowski
19th March 2021
In this article we will briefly describe the difference between object and class in Scala.
An object is a singleton instance of a class. For every object in the code, an anonymous class is created, which inherits from whatever classes you declared object to implement.
Objects as static method holders
Quite often you will need an object to be host for some methods that shall be available without having to first instantiate an instance of some class. This use is closely related to static members in Java.
object MyObject {
 def addOne(n: Int): Int = n + 1
You can then call above method using MyObject.addOne(3).
If addOne were a member of some class A, then you would need to make an instance first:
class MyClass() {
val myClass = new MyClass()
You can see how redundant this is, as addOne does not require any instance-specific data.
Objects as a special named instance
You can also use the object itself as some special instance of a class or trait. When you do this, your object needs to extend some trait in order to become an instance of a subclass of it.
Consider the following code:
object A extends B with C {
 // some methods
This declaration first declares an anonymous (inaccessible) class that extends both B and C, and instantiates a single instance of this class named A.
This means A can be passed to functions expecting objects of type B or C or B with C.
Additional features of objects
There also exist some special features of objects in Scala. I recommend to read the official documentation.
def apply(...) enables the usual method name-less syntax of A(...) def unapply(...) allows to create custom pattern matching extractors def copy(...) allows to create a copy of an instance with some parameters changed if accompanying a class of the same name, the object assumes a special role when resolving implicit parameters.
To sum up:
 - class C defines a class, just as in Java
 - object O creates a singleton object O as instance of some anonymous class. It might be used to hold static members that are not associated with instances of some class.
 - object O extends T makes the object O an instance of trait T. You can then pass O anywhere, a T is expected.
 - if there is a class C, then object C is the companion object of class C. Note that the companion object is not automatically an instance of C.
If you have still some concerns you can always reach out to the documentation for classes and objects.

Importing Data from Relational Database
R has certain limitation regarding the processing of extremely large dataset and doesn't support concurrent access to data. A Relational Database Management System on the other hand is capable of providing fast access to selected portions of the big data, and can provide concurrent access from multiple users running on various hosts. There are various R packages that can be used to communicate with RDBMS, each with a different level of abstraction. Some of these packages have the functionality of copying entire data frames to and from databases. Some of the packages available on CRAN for importing data from Relational Database are:
- RSQLite (This packages is used for bundled DBMS SQLite)
- RJDBC (This package uses Java and can connect to any DBMS with a JDBC driver)
- RMongo (This is an R interface for Java Client with MongoDB)
RMySQL package is an interface to MySQL DBMS. The current version of this package requires DBI package to be pre-installed.
The function dbDriver("MySQL") returns the database connection manager object, which can be followed up by functions like dbConnect and dbDisconnect to open a database connection and close the connection, respectively. Packages such as RSQLite, RPostgreSQL and ROracle needs to be installed before working on these DBMS using their respective call functions, dbDriver("SQLite"), dbDriver("RPostgreSQL"), dbDriver("Oracle").
Learn Data Science by working on interesting Data Science Projects
- dbGetQuery sends the queries and fetches results as the data frame.
- dbSendQuery only sends the query and returns an object of class inheriting from "DBIResult", this object of class can be used to fetch the required result.
- dbClearResult removes the result from cache memory.
- fetch returns few or all rows that were asked in query. The output of fetch function is a list.
- dbHasCompleted is used to check is all the rows are retrieved.
- dbReadTable and dbWriteTable functions are used to read and write the tables in Database from an R data frame.
>library(RMySQL) >connection <-dbConnect(dbDriver("MySQL"), dbname = "Test_Database") ## Assuming that we are using MySQL tables for DBMS >dbListTables(connection) ##Loading a data frame into database >data(Sample_Data) >dbWriteTable(connection, "Column1", Sample_Data, overwrite=True) ## To read the Column1 of in the database >dbReadTable(connection, "Column1") ## Selecting from the loaded table as a query >dbGetQuery(Connection, paste(Row_Name, Variable_Name, Condition))
RODBC package provides an interface to database sources supporting on ODBC interface. This package is widely used because it needs the same R code to import data from different database system. RODBC package works on OS X, Windows and Unix/Linux across most of the database systems such as, MySQL, Microsoft SQL Server, Oracle, PostgreSQL.
- odbcConnect and obdcDriverConnect functions are used to open a database connection.
- odbcGetInfo function will provide details about the client and server.
- odbcClose function is used to close the database connection.
- sqlSave function saves the R data frame in argument into the database table.
- sqlFetch does the opposite, by saving the database table into an R data frame.
- sqlQuery is used to send an SQL query to the database, which returns an R data frame.
In the example mentioned below, we are using a PostgreSQL with an ODBC driver.
>library(RODBC) >connection <- odbcConnect("Sample_Database", uid="Name", case="tolower") >data(Sample_Data) >sqlSave(connection, Sample_Data, rowname="Row1", addPK=TRUE) >rm(Sample_Data) >sqlQuery(connection, "Select_Column, Condition")
Importing Data from Non-Relational Database
R also has packages that support non-relational database for data import.
- rhbase is used for Hadoop Distributed File System
- RCassandra is used for Cassandra Database system
- Rmongodb is used for MongoDB.
>Library(rmongodb) >SampleDatabase <- "Test_Database" >MyMongoDB <- mongo.create(db=SampleDatabase) ## To insert a list >mongo.insert(MyMongoDB, "Test_Database.Column1", list.name)


Eco-Friendly Project with Cay-Shred begins at Beacon Farms
In December 2020, Beacon Farms received the first load of shredded paper from Cay-Shred Mobile Data Destruction. The load delivered weighed roughly 6,000 lbs - that is 6,000 lbs. less waste dumped at the George Town landfill!
Beacon farms will incorporate this shredded paper with our other compost inputs, such as green waste from landscapers, brown waste in the form of wood chips and create a nutrient rich compost product.
Cay-Shred will be delivering similarly sized load each week. This situation benefits everyone involved as we are reducing the volume of waste going to the dump by recycling a waste product and turning it into a valuable growing medium that will in turn make Beacon Farms' soil more productive.

To convert 1 gram of salt into teaspoons, multiply 1 gram by 0.17. Although the conversion is not exact, there are approximately 6 grams in every teaspoon, translating to about 0.17 teaspoons per one gram.
- Measure the salt in grams
Use a kitchen scale to measure your salt in grams. Write down how much the salt weighs in grams.
- Multiply the amount of salt in grams by 0.17
The conversion from grams to teaspoons for salt is not exact. A gram is a measurement of mass, while a teaspoon is a measure of volume. Converting a measurement of mass to a measurement of volume can be done, but the result is approximate. If you have one gram of salt, you therefore must multiply by 0.17 in order to determine the salt's measurement in teaspoons.
- Use an online conversion calculator
If you want to calculate different measurements of salt from grams to teaspoons, go to TraditionalOven.com. In the search bar on the homepage, search for "salt converter", then click the first link. Once on the calculator, type the amount of salt in grams into the converter and hit Enter. The calculator automatically generates the conversion of salt from grams to teaspoons. You can also click "from teaspoons into grams" if you wish you toggle the conversion.

On the integrity of domination in graphs.
This thesis deals with an investigation of the integrity of domination in a.graph, i.e., the extent to which domination properties of a graph are preserved if the graph is altered by the deletion of vertices or edges or by the insertion of new edges. A brief historical introduction and motivation are provided in Chapter 1. Chapter 2 deals with kedge-( domination-)critical graphs, i.e., graphsG such that )'(G) = k and )'(G+e) < k for all e E E(G). We explore fundamental properties of such graphs and their characterization for small values of k. Particular attention is devoted to 3-edge-critical graphs. In Chapter 3, the changes in domination number brought aboutby vertex removal are investigated. \ Parameters )'+'(G) (and "((G)), denoting the smallest number of vertices of G in a set 5 such that )'(G-5) > )'(G) ()'(G -5) < )'(G), respectively), are investigated, as are'k-vertex-critical graphs G (with )'(G) = k and )'(G-v) < k for all v E V(O)). The existence of smallest'domination-forcing sets of vertices of graphs is considered. The bondage number 'Y+'(G), i.e., the smallest number of edges of a graph G in a set F such that )'(G- F) > )'(0), is investigated in Chapter 4, as are associated extremal graphs. Graphs with dominating sets or domination numbers that are insensitive to the removal of an arbitrary edge are considered, with particular reference to such graphs of minimum size. Finally, in Chapter 5, we-discuss n-dominating setsD of a graph G (such that each vertex in G-D is adjacent to at least n vertices in D) and associated parameters. All chapters but the first and fourth contain a listing of unsolved problems and conjectures.

International Inspiration is developing curriculum resources and training teachers in tandem with the Malaysian Government's major Transformation Curriculum initiative. With an initial focus on children with a disability and the most marginalised children living in the states of Sabah and Perak, International Inspiration's benefits will spread across the whole country in the longer term. International Inspiration will also contribute to the highly-prized national youth leadership movement, providing new models of training that draw out the potential of young people, and provide them with the skills to take the lead in their own communities.
Reasons to celebrate
- 48 teachers and lecturers have been trained to use resources with a focus on disability sport and inclusion.
- 600 teachers have been trained in the first year of training across Malaysia.
- 12 teachers and 100 young sports leaders have been trained initially to deliver sports festivals in their communities.
- By March 2011 a further 500 young sports leaders had been trained and a further 50 sports festivals arranged, involving more than 15,000 primary-aged pupils.
Influencing the nation as a whole
The Government of Malaysia has demonstrated its confidence in the programme by undertaking to drive and support the roll-out of International Inspiration curriculum models piloted in Sabah to all 13 states.
Improving behaviour and having fun
Ravichan Dran is a PE teacher in Malaysia. Through International Inspiration, a teaching technique using PE training cards has been introduced into Ravichan's school, which has led to an improvement in lessons.
Ravichan said that International Inspiration has enabled him to gain access to new materials and resources used in UK schools, which is of great benefit to teaching and learning activities in the school, with pupils 'having more fun learning'.
In addition, this teacher training has resulted in improved behaviour amongst pupils, and importantly, enabled Ravichan to go on to train other teachers in these new techniques, thereby leaving a lasting legacy.
Ravichan said: 'PE has become more fun for pupils and has given me more knowledge and skills in carrying out activities in sports in schools. It has benefited the children in educating them in the importance of sport in their lives. Problem students' discipline has improved when given the chance to be leaders in sport.'

How to Calculate Fixed Asset Turnover in NetSuite
Making the most of your NetSuite data
What is Fixed Asset Turnover?
Fixed asset turnover is a financial metric that measures the efficiency of a company's fixed assets. Fixed assets are assets that are not easily converted into cash and are used in the production of a company's goods or services.
Fixed assets include things like factories, machinery, equipment, and vehicles.
Fixed asset turnover is calculated by dividing the company's net sales by the total value of its fixed assets.
Fixed asset turnover is a good metric to use when comparing companies in the same industry.
How do you calculate Fixed Asset Turnover in NetSuite?
It can be difficult to calculate Fixed Asset Turnover directly inside of NetSuite; that's where Causal comes in.
Causal is a modelling tool which lets you build models on top of your NetSuite data. You simply connect Causal to your NetSuite account, and then you can build formulae in Causal to calculate your Fixed Asset Turnover.

No burning before 4 p.m.
Virginia's 4 p.m. Burning Law went into effect Friday, February 15—the start of spring fire season in Virginia. The law prohibits burning before 4 p.m. each day until April 30 if the fire is in, or within 300 feet of, woodland, brushland or fields containing dry grass or other flammable materials.
This law has been on the books since 1950 and has been credited with saving hundreds of thousands of acres from the damages of wildfires. "The 4 p.m. Law is one of the most effective tools we have in the prevention of wildfires," said John Miller, director of resource protection at the Virginia Department of Forestry (VDOF). "By adhering to the law and not burning before 4 p.m., people are less likely to start a fire that threatens them, their property and the forests of Virginia."
Why 4 p.m.? After 4 p.m. the winds calm, the temperature decreases, and the humidity increases—factors that contribute to safer burning conditions.
A violation of the 4 p.m. law is a Class 3 Misdemeanor punishable by a fine up to $500, the cost of damages, and the cost of fire suppression efforts.

Using Foresight to Cope with Uncertainty
MetadataShow full item record
In an increasingly uncertain world where resources are limited, foresight thinking and approaches provide a critical way for governments and communities to understand and plan for the future. Using foresight techniques can contribute to the development of policies that are robust and fit for purpose. Foresight practitioners have an important role to play in the design and implementation of these processes. However, more needs to be done to ensure that such initiatives are properly supported and the capacity of policy thinktanks and foresight practitioners strengthened in developing country contexts. Increasingly, foresight processes should harness advances in information and communication technology (ICT) to facilitate broader citizen participation in policymaking.
