TY - JOUR T1 - Association between food insecurity and gestational diabetes mellitus: A casecontrol study TT - ارتباط ناامنی غذایی با دیابت بارداری: مطالعه ی مورد_ شاهدی JF - sjsph JO - sjsph VL - 13 IS - 3 UR - _URL_ Y1 - 2015 SP - 73 EP - 84 KW - Food insecurity KW - Gestational diabetes mellitus KW - Pregnant women N2 - Background and Aim: Diabetes mellitus is one of the most common medical problems in pregnant women. Nutrition plays an important role in the prevention and control of this disease. Some studies have found a relationship between gestational diabetes mellitus (GDM) and food insecurity. The objective of this study was to investigate the association between food insecurity and GDM. Material and Methods: : This case-control study included 274 pregnant women (137 GDM cases and 137 healthy controls) selected by convenience sampling. Data on the subjects' food insecurity, demographic features and physical activity (MET) were collected by interviewing and their heights and weights measured. For the analysis of the data, the Chi-square test, independent sample t-test and multivariate and univariate logistic regression tests were used, the statistical software being SPSS 16.0. Results: On the whole, 18.2% and 21.9% of the women in the case and control groups suffered from food insecurity, respectively. There were statistically significant differences between the case and control groups with regard to a previous history of pregnancy, a family history of diabetes in the first and second degree relatives, and a history of giving birth to a baby weighing over 4 kgs. Further analysis of the data showed a family history of diabetes mellitus and a low socio-economic status to be independent risk factors for GDB. Conclusion: No statistically significant difference was observed between food insecurity of the women and gestational diabetes mellitus in this study. Despite this finding, considering that there are associations between food insecurity and other types of diabetes mellitus, we recommend further studies on this subject to be able to either accept or reject the hypothesis on the association between food insecurity and gestational diabetes mellitus.

I've been asked to prove this.
In class we proved this when $n=15$, but our approached seemed unnecessarily complicated to me. We invoked Sylow's theorems, normalizers, etc. I've looked online and found other examples of this approach.
I wonder if it is actually unnecessary, or if there is something wrong with the following proof:
If $|G|=35=5\cdot7$, then by Cauchy's theorem, there exist $x,y \in G$ such that $o(x)=5$, $o(y)=7$. The order of the product $xy$ is then $\text{lcm}(5,7)=35$. Since we've found an element of $G$ of order 35, we conclude that $G$ is cyclic.

I can't see what's wrong with it, but I have a hard time believing that so many people would overlook this proof it it were correct. – user18297 Oct 26 '11 at 17:58
If $x$ and $y$ commute then the order of $xy$ is the lcm, but you can't assume this. – stopple Oct 26 '11 at 18:03
In fact, even if $x$ and $y$ have finite order, it need not be that $xy$ has finite order. – JavaMan Oct 26 '11 at 18:05
(following DJC's comment) e.g. We can express the Fibonacci matrix (with infinite order) as the product of two matrices with finite order (the orders are 2 and 3, if memory serves). – The Chaz 2.0 Oct 26 '11 at 18:07
So try applying this to a group of order 21. What goes wrong (since there is a non-abelian group of that order, which is therefore non-cyclic - as every cyclic group is abelian)? If you can't distinguish the cases, you don't have a proof. – Mark Bennet Oct 26 '11 at 18:07

As a concrete example, consider the single-cycle permutations $(1,2,3,4,5)$ and $(1,2,3,4,5,6,7)$, with orders $5$ and $7$, respectively. Their product is the cycle $(1,3,5,2,4,6,7)$ of order $7$.
On the other hand, pick two arbitrary axes in $\mathbb R^3$ and consider the groups of five-fold and seven-fold rotation symmetry about these axes. These are cyclic groups of orders $5$ and $7$, respectively, but the product of two elements, one from each group, is generally not a rotation through a rational multiple of $\pi$, and is thus generally of infinite order. You can see this by varying one of the axes; then the rotation angle of the product varies continuously with the orientation of the axis, and thus by the intermediate value theorem takes on irrational multiples of $\pi$.

Here's a counting argument. If $G$ is not cyclic, then every element of $G$ is of order $1$, $5$, or $7$, and, as noted above, no element of order $5$ commutes with any element of order $7$.
Let $G_5$ be the elements of order $5$. We can see that $4\mid|G_5|$ by partioning $G_5$ into sets $\{g,g^2,g^3,g^4\}$.
On the other hand, given a $y$ of order $7$, we can partition $G_5$ into sets of $7$ elements, since we can separate $G_5$ into sets $\{g,ygy^{-1},y^2gy^{-2},...,y^6gy^{-6}\}$ (Note that, if $y^igy^{-i} = y^jgy^{-j}$, then $y^{i-j}g = gy^{i-j}$. So this must give $7$ distinct values, or some y^{i-j} commutes with $g$, which would imply that $G$ is cyclic.)
So, $28\mid |G_5|$. Similarly, $30\mid |G_7|$. But $35 = 1 + |G_5| + |G_7|$

Note, this works for any $|G|=pq$ where $p,q$ distinct primes and $(pq,(p-1)(q-1))=1$. On the other hand, if $p=2$, then there is a dihedral group of order $2q$ for all $q$. And if $p\mid (q-1)$, we can find a cyclic group of automorphism of $(\mathbb{Z}_q,+)$ of order $p$ by taking powers of an elements of $\mathbb{Z}_q^\times$ of order $p$, and take the semidirect product of the groups to get a non-cycle group of order $pq$. – Thomas Andrews Oct 26 '11 at 19:20

Another explicit example:
Consider $$ A = \left( \begin{array}{cc} 1 & -1 \\ 0 & -1 \end{array} \right), \quad \text{and} \quad B = \left(\begin{array}{cc} 1 & 0 \\ 0 & -1 \end{array} \right). $$ Then, $A^2 = B^2 = I$, but $$ AB = \left( \begin{array}{cc} 1 & 1 \\ 0 & 1 \end{array} \right) $$ has infinite order.
It should also be mentioned that if $x$ has order $n$ and $y$ has order $m$, and $x$ and $y$ commute: $xy = yx$, then the order of $xy$ divides $\text{lcm}(m,n)$, though the order of $xy$ is not $\text{lcm}(m,n)$ in general. For example, if an element $g \in G$ has order $n$, then $g^{-1}$ also has order $n$, but $g g^{-1}$ has order $1$. Joriki's example also provides a scenario where the order of $xy$ is not $\text{lcm}(m,n)$ in general.

That's what I was talking about in my comment (though $AB$ here is the transpose...) – The Chaz 2.0 Oct 26 '11 at 18:54

I think we can prove this in more generality if we have that $|G|=pq$ with $p,q$ prime, $p> q$ and $q\not |(p-1)$
From the Sylow theorem we then have that the number if sylow-p groups is $1$ and then as:
$|Sylw_q|\equiv 1 mod q$ and $|Sylw||p$ but $q\not | p$ this then gives that the number of Sylow q-groups is also $1$
We then have that $G=C_p\times C_q$ and hence is abelian and so if we let $C_p=$ and $C_q=$ then we have $o(gh)=lcm(o(g),o(h))=lcm(p,q)=pq$ and hence we have that $G$ is cyclic

Database Index Page Row Order
A few weeks ago I was asked a great question by Sam, who follows my blog. With Sam's permission, I am reprinting has question about indexes here.
Sam asks (my highlights) :
"We are told that we can have only one Clustered Index since we can actually sort the data in only one way. However, a clustered index orders data in the leaf pages in sequential order, but does not order the data within that page itself to be in sequential order. Since the data on the page itself is not sorted sequentially (and thus implying more than one way of possible order), I am confused by the "Since we can sort data only in one way we can't have more than 1 clustered index" reasoning."
Does Physically ordering rows inside database pages make sense?
For example, let us say there is a clustered index on the names of World Cities and let us say that names starting with A and B fall on the first page; names starting with C and D fall on second page. And let us say that on the first page, we have the cities Atlanta, Bombay and Boston and on the second page we have the cities Cleveland, Delhi and Detroit.
In the above scenario, the data could have been stored in the following manner in the Clustered Index:
Page 1 (A to B):
Page 2 (C to D):
Since, the data on the page itself is not sorted sequentially, it is also possible to store data in another order as follows:
Page 1 (A to B):
Page 2 (C to D):
So, while it is logically possible, in reality we cannot create another clustered index, where the order of data across pages is still maintained, but the order within the page can be different.
Can you give your reasons/opinions here?
Another aspect of this question is, is there any reason SQL Server does not order the data within an individual page of a clustered index? Is it because it may be more expensive to re-arrange data within the page for every insert but cheaper to insert within the page in whatever order but rely on Row Offset information?
These are excellent questions that touch on some great areas of computer science. I am always happy to give my opinion.
Illustrating the Issue
Before I move on to the opinion bit, I would like to show you a repro that makes illustrates Sam's point that rows are not physically ordered within the page.
Consider this simple table:
USE tempdb
WHILE _USER_ < 1000 BEGIN
/* Create semi random numbers, correcting for horrible SQL Server hash function */
SET _USER_ = ABS(BINARY_CHECKSUM(_USER_, _USER_, 'A')) % POWER(2,30)
PRINT (sys.fn_varbintohexstr(CONVERT(BINARY(4), _USER_)))
INSERT INTO Foo (K) VALUES (sys.fn_varbintohexstr(CONVERT(BINARY(4), _USER_)))
SET _USER_ = _USER_ + 1
This will create a table with 100 rows inserted in a random order Now, let us have a quick look at the pages in the table:
DBCC IND (2, 'Foo', 1)
Pick any PagePID with PageType = 1 and inspect the page with:
DBCC PAGE (2,1,,2)
Here is what I get on my machine from the DATA dump:
0000000071CAA064: 0x000002e1__________
0000000071CAA078: _____________…..%.
0000000071CAA08C: 0x00002f51__________

0000000071CAA190: _____________…..%.
0000000071CAA1A4: 0x00444590__________
As you can see, the data in the page is not physically ordered on the page. However, let us just see how the slots map on the page:
DBCC PAGE (2,1,,1)
From my machine:
Slot 19, Offset 0xd8, Length 40, DumpStyle BYTE
0000000000000000: ..%.0x002f7651______
Slot 80, Offset 0x128, Length 40, DumpStyle BYTE
0000000000000000: ..%.0x032e2c70______
As you can see, the slots on the page are not in the same order as the physical layout of the data. In fact, the slots are ordered as per the index.
Physical vs. Logical Order
By using an indirect mapping of row slots to physical locations on the page, we can use a simply binary search to quickly locate a specific row within the 8K page. Unlike on disk, there is no such thing as "defragmenting" a page to make the physical order match the mapping order.
Would it be worth doing this and paying the cost of keeping rows physically ordered (maybe even in different ways, depending on access pattern).
First, consider why we worry about logical and physical order in the first place. We do this to get more sequential instead of random I/O on spinning media. This optimisation drives down cost when running on hard drives – but is largely irrelevant on SSD. However, once a page is in memory, the issue of sequential I/O is no longer a problem we need to worry about, we can fall back on old fashioned binary searching. It would therefore seem that it makes no sense to pay the extra cost of keeping the rows physically sorted on the page, because once they are in memory, its fast to find them.
Second, consider the additional cost of logging physical reordering of the pages during inserts and update operations. We would have to log not only the changes in the map, but also which rows were shifted around in the data when a new row is inserted. This makes inserts more expensive and would make page splits, already expensive, more complex.
So far, everything seems to indicate that SQL Server has chosen the right balance with regards to the page map logical order vs. the data physically ordered on the page.
Random and Sequential Memory
The cost of locating a row within 8K of data using a binary search might seem trivial compared to the cost of bringing data from disk to memory in the first place. However, once you consider modern systems that largely run in memory or have very fast disk – the cost you pay to find stuff, even if you know it is memory resident, becomes interesting.
It turns out that it matters quite a bit how you access memory. It takes around 100 CPU cycles to get 64B or 128B of memory from DRAM to the CPU. This quickly adds up and the CPU reports itself as busy while waiting for that memory (there is no such thing as a "CPU waiting for memory" wait stat). I have blogged about sequential memory access here:
Joe Chang also made the interesting observation that decoding exactly where the data you need to look at next is locate is a very CPU intensive operation:
All this indicates that there might be a better way to store data inside pages in SQL Server. For example, if you use a column store, physically reordering the rows, as suggested by Sam, inside the pages can lead to better compression. I have blogged about this here:
Sam's question hints at another interesting option, namely to not bother maintaining a sorted row map at all. Because visiting memory sequentially is quite a bit faster than visiting it randomly, it may simply be better to visit all the rows in a page instead of trying to be smart about finding the one you are looking for. Such a a memory efficient access pattern has been suggested (and proven) to work in this article:
If the rows were stored sorted, it might even be possible to write a "forward only" search that
In this blog, inspired by Sam's question, I have been musing over the trade-offs you have to make when storing data inside the pages of a database. There is quite a bit of performance to be found here by optimising for different workloads and CPU architectures. It is the subject of a lot of research and by following the links above, you can start to dig deeper.

Year of Project: 2012
Name of Project: Arkansas ReLeaf
Number of Trees to be Planted: 0
Project Name: Arkansas ReLeaf
Number of Trees: 150
American Forests paired with Arkansas Releaf to help the city of Marmaduke, which has been impacted by natural disasters. Marmaduke was hit by a tornado in 2011 — two years after it was devastated by an ice storm — costing the city much of its tree canopy. To restore the lost trees, Arkansas Releaf held a planting event for Arkansas' official Arbor Day. Twenty-nine large trees were planted throughout one of Marmaduke's parks to help provide immediate shade. A hundred smaller trees were distributed to community members, and 500 pine seedlings were presented to a local Boy Scout troop to plant. This project aimed to not only help restore the tree canopy of Marmaduke, but educate community members on different tree species, selection and placement.

Female diksa guru: how to solve this complicated discussion?
The discussion about if qualified ladies should also be allowed to initiate disciples is still going strong inside our movement. Both sides have plenty of arguments to sustain their conclusions and therefore the discussion can go on eternally. Although there are still no confirmed deaths, it seems that it's just a matter of time...
What makes this discussion so complicated is because it has two sides: the philosophical and the cultural side. If we fail to separate these two sides, the arguments will interpolate and it will be practically impossible to reach a conclusion. In fact, it becomes difficult even to understand where the disagreement is! When this happens, people become exalted, the offenses start and the material modes overcome us.
The first is the philosophical side, if ladies giving diksa are allowed or not, according to our vaishnava philosophy. In this part of the discussion, two questions should to be answered:
1- According to vaishnava philosophy, could, hypothetically, a qualified lady initiate disciples?
2- In case of an affirmative answer, what would be the necessary qualifications?
The important part about this first part of the argument is that it must be conducted solely on a philosophical basis. The point is not about if a certain person could be allowed to initiate or not, but if a vaishnavi guru is an idea acceptable or not according to vaishnava philosophy and according to the instructions left by Srila Prabhupada.
If the conclusion of the first part is that qualified ladies could initiate, the second part of the argument could start.
The second part should answer the following question:
3- Considering all cultural, psychological, political and practical aspects, as well as the pros and cons, should qualified ladies be allowed to initiate in ISKCON?
We can see that the second part is actually more complicated than the first, because it includes different practical aspects of the question and also a discussion of the pros and cons. However, if the philosophical side is already agreed upon on the first part, the discussion becomes more streamlined and less vicious. Here, no quotes from sastra are needed: the discussion can be focussed on practical points. Here, questions like a possible negative reaction from indian society and from members of other vaishnava sampradayas, cultural aspects, resistance from sectors of our society, as well as potential risks and benefits could be separately discussed. The conclusion could be to allow hypothetical qualified ladies to initiate, or not.
We can see that it is perfectly possible that an agreement could be reached on the sastric possibility of a qualified lady accepting disciples, but at the same time be concluded that the risks of implementing this inside of our society outweigh the benefits. Maybe it's too soon, maybe it would not be positive for our families, maybe it would be too dangerous, and so on.
Only if the second part of the argument would also result in a positive answer to the question, individual cases of ladies that could potentially fill the role could be discussed. Then, all the arguments related to the suitability of particular candidates could be examined, without mixing with other aspects of the discussion. It could be that in the end no candidates would show the necessary qualifications for such an important role, which would also conclude the discussion.

Create a slide with hypertext that points to a URL for the simulation
that you want to use. During the lecture, click on the hypertext to
access the desired simulation. Run the simulation. When you are done
using the simulation, use the back arrow button on your web browser
toolbar to return to your slide show.
If you do NOT have fast Internet access in the lecture room:
STEP1. To teach with the desired simulation in an area without fast
Internet access, first access the simulation from a laptop, notebook
or portable computer at a nearby location with Internet access. Once
the simulation is working the computer can be disconnected from the
Internet. Make sure your battery has sufficient charge for the trip.
Keeping your portable computer powered and your web-browser running,
transport the computer to the location without Internet access and you
should be able to use the simulation there. If you will use the VAM
simulation and your laptop goes into "sleep" mode, click on
"Reset" (on the orange column on the right of the VAM simulation
screen) and then "Pause Simulation" (an instructor VAM feature)
before transport. When you arrive at the lecture hall, click on "Reset"
before using the VAM simulation.
STEP 2. Create your Powerpoint presentation and create a page with placeholder
text to remind you to go to the simulation. Open your Powerpoint slide
show. When you get to the reminder slide, press the "Alt"
and "Tab" buttons simultaneously. A series of icons representing
the different programs running should be displayed. To navigate to and
select the desired program, keep the "Alt" key down while
pressing and releasing the "Tab" key until the desired icon
is selected. When the icon representing the browser running the simulation
is selected, a square will appear aroud the "e" icon if you
are using Microsoft Internet Explorer. When the desired icon is selected,
release the "Tab" key to bring that program "to the front".
When you are done using the simulation, use the "Alt"/"Tab"
key combination to select the Powerpoint slide show icon and resume

Mechanical pencils
Mechanical Pencil
A mechanical pencil is a pencil containing solve pencil leads fed up with either a push mechanism or swivel mechanism. The pins typically have a thickness of 0.5 to 0.9 mm and are made of graphite powder mixed with a clay. The more graphite that is in the diocese, the softer it becomes, and vice versa. The first mechanical pencil was invented in 1914 and is usually attributed to American Charles R. Keeran, but the fact is that Japan named Tokuji Hayakawa developed the same technology basically simultaneously.


Communicating with Symbols and Codes
When you think of telecommunications today, what comes to mind? Fiberoptic lines? Satellites? Massive global networks? Those certainly help define modern telecommunications, but it's not all high tech wizardry. In fact, mankind has long used low tech measures to communicate across distances with symbols and codes helping to make it possible despite the actual delivery mechanism. Below are a few examples of how we have communicated with symbols and codes over time.
Symbols and Communicating Ship to Ship
Symbols with colorful and with bold patterns, nautical flags represent much more than fanciful boat decor. They were, and still are, used to communicate from ship to ship and from ship to shore. Nautical flags are an international code system consisting of 26 square flags (one for each letter of the alphabet) along with 10 numbered pennants. Not only can nautical flags be used to spell out messages alphabetically, one-flag signals have specific internationally-understood meanings. For example, the 'O' flag, when flown alone, means "man overboard"; 'V' means assistance is needed; 'W' means medical assistance is needed; 'J' means the vessel is on fire and to stay back. Each letter, except for 'R', has a specific meaning.
Morse Code
As you likely know, Morse code was used to send messages over the telegraph. Each letter of the alphabet was assigned a set of dots or dashes which could be relayed by tapping the telegraph key to match. Dots required a quick tap while dashes were held slightly longer. For example, the term "save our ship" — or SOS — in Morse code translates to "… – – – …" ('s' is three dots; 'o' is three dashes; and 's' once again is three dots). In addition to using Morse code over telegraphs, sailors used it with lamps to transmit their messages from ship to ship or from ship to shore.
As old-fashioned as Morse code may sound, it's still in use today. In fact, the U.S. Navy has created a flashing light to text converter system (called the Flashing Light to Converter System) that converts text messages to Morse code, transmits them via a signal light, and then converts the Morse code back to text message. Now, sailors can simply enter a text message and transmit it via light signals to another ship, which can either translate the Morse code by hand or use its own Flashing Light to Converter System unit to read the actual text message.
Pager Codes
In the 1980s and 1990s when pagers were all the rage and before alphanumeric support became available, pager code was developed. Pager code used numbers that resembled letters (for example, the number 3 looks like a backwards E; thus, 3 = E). According to Urban Dictionary, page code is as follows:
A=6 B=8 C=0 D=0 E=3 F=7 G=9 H=4 I=1 J=7 K=15 L=7 M=177 N=17 O=0 P=9 Q=9 R=12 S=5 T=7 U=17(or 11) V=17(or 11) W=111 X=25 Y=4 Z=5.

Symbols | From Emoticons to Emoji
Finally, let's take a look at the ever-popular emoticon 🙂 and emoji 😀. Emoticons came first and were used to convey human emotion in icon form. They began to immerge in the early 1980s. Using just your keyboard, you can convey your feelings. For example, 😉 is an emoticon for winking while :-/ indicates skepticism or annoyance. In 1999, Japanese artist Shigetaka Kurita, a member of the "i-mode" development team for a cellphone carrier, designed an a set of 12-by-12-pixel images that could be selected and sent via the i-mode interface — and the emoji was born. Today, an estimated 92 percent of all people use emoji. In a way, we've come full circle to the early days of creating cave art to communicate.

Just so you know: Canned sardines are kosher.
This judgment would appear to be definitive, based on DNA evidence. Genetic testing by a parasitologist at the American Museum of Natural History has confirmed that the recent discovery of small worms in canned sardines does not render them treyf, or unkosher. It may render them unappetizing, but that judgment is up to the consumer (more on that later).
The museum got involved last March when rabbis from the Orthodox Union, which certifies as kosher hundreds of thousands of products across the world, sought scientific help in resolving a question that arose when they began finding the worms, or nematodes, in cans of sardines.
Talmudic debates can turn on fine distinctions, but this was relatively straightforward. The presence of worms could have been a sign that, during the preparation of the canned sardines, muscle from the fish had been improperly handled and allowed to mix with intestinal contents of the sardines, rendering them unkosher.
The issue was important because it "could have led to sardines losing certification as kosher," said Dr. Mark Siddall, a curator and professor in the invertebrate department of the museum, who conducted the testing. Many consumers, including non-Jews, look for the certification label as a sign of quality assurance in food preparation.
The rabbis brought their samples of sardina pilchardus — the Mediterranean sardine — to the museum, where Dr. Siddall conducted so-called "DNA bar-coding" to analyze the species of the worms. Their DNA was isolated and two variants of the cytochrome oxidase gene — which is different for every animal species, as unique as a fingerprint, Dr. Siddall said — revealed that the type of worms in the samples reside only in the flesh of sardines. "This meant that there was no evidence that the intestines and the flesh had been commingled," Dr. Siddall said.
The Orthodox Union also discovered evidence of worms in cans of orange capelin roe, and Dr. Siddall's testing confirmed that the worms, as well, were not intestine-dwellers. The analysis of Dr. Siddall and his colleagues has been published in The Journal of Parasitology, and the union has formally ruled that both the sardines, and the capelin roe, are kosher. (The entire paper can be read below.)
In 2004, a similar Talmudic tempest involved a tiny crustacean known as a copepod, which was discovered swimming in New York City's tap water, spurring debate among the observant about whether it rendered city water unkosher. Many contended that the crustacean was a distant relative of shrimp and lobster, shellfish that cannot be consumed because they lack fins and scales. The Orthodox Union recommended that city water be filtered before using it for drinking and cooking. That prompted restaurants to install filters, some costing more than $1,000, to remove the interlopers.
As for worms in sardines or in any fish, Article 81 of the New York City Department of Health Code has long required that "aquatic animals, fish or molluscan shellfish" be cooked, rendering such parasites harmless — unless customers assume some risk by asking for raw fish, as in sushi. The best sushi masters constantly examine the fish for evidence of parasites.
"The notion that there are worms in fish flesh is not new," Dr. Siddall said. "As long as they're cooked, or frozen first, they're perfectly safe."
Yes, but if the sardines are both safe and kosher, are the worms themselves — which are barely visible and look like thin whitish threads — disgusting?
"It is up to the individual's aesthetic as to whether that is 'yucky,' " Dr. Siddall said. "I've eaten worse. Curdled goose blood. Rhino beetle larvae. Both yummy. But that's another story."

Studies investigating the association between Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections and intrahepatic cholangiocarcinoma (ICC) have reported inconsistent findings. We conducted a meta-analysis of epidemiological studies to explore this relationship.
A comprehensive search was conducted to identify the eligible studies of hepatitis infections and ICC risk up to September 2011. Summary odds ratios (OR) with their 95% confidence intervals (95% CI) were calculated with random-effects models using Review Manager version 5.0.
Thirteen case-control studies and 3 cohort studies were included in the final analysis. The combined risk estimate of all studies showed statistically significant increased risk of ICC incidence with HBV and HCV infection (OR = 3.17, 95% CI, 1.88-5.34, and OR = 3.42, 95% CI, 1.96-5.99, respectively). For case-control studies alone, the combined OR of infection with HBV and HCV were 2.86 (95% CI, 1.60-5.11) and 3.63 (95% CI, 1.86-7.05), respectively, and for cohort studies alone, the OR of HBV and HCV infection were 5.39 (95% CI, 2.34-12.44) and 2.60 (95% CI, 1.36-4.97), respectively.
This study suggests that both HBV and HCV infection are associated with an increased risk of ICC.

This paper studies the performance based vulnerability assessment of midrise masonry structures against seismic activity using Extreme Loading® for Structures (ELS).
A thorough four-step performance-based seismic evaluation for a six-story unreinforced masonry building is conducted. Incremental dynamic analysis is carried out using the applied element method to take advantage of its ability to simulate progressive collapse of the masonry structure including out-of-plane failure of the walls. The distribution of the structural responses and inters-tory drifts from the incremental dynamic analysis curves are used to develop both spectral-based (Sa) and displacement-based (interstory drift) fragility curves at three structural performance levels. The curves resulting from three-dimensional (3-D) analyses using unidirectional ground motions are combined using the weakest link theory to propose combined fragility curves. Finally, the mean annual frequencies of exceeding the three performance levels are calculated using the spectral acceleration values at four probability levels 2%, 5%, 10%, and 40% in 50 years. The method is shown to be useful for seismic vulnerability evaluations in regions where little observed damage data exists.

Kinetics and morphology of homoepitaxial diamond growth by chemical vapor deposition
Rawles, Robin E.
D'Evelyn, Mark P.
Doctor of Philosophy
To address the relative lack of understanding concerning growth mechanisms for diamond chemical vapor deposition (CVD), this work explores kinetics of diamond epitaxy--growth on single-crystal substrates--and morphology of diamond surfaces--CVD films and natural and synthetic diamond after hydrogen plasma treatment. Optical Fizeau interferometry was implemented for in situ growth-rate measurements, providing a facile and sensitive means of systematically studying diamond growth kinetics. Fizeau interferometry was also used for non-contact temperature measurement of diamond single crystals, and the index of refraction variation with temperature was determined. Kinetics of diamond (100) homoepitaxy was investigated--in particular, the effects of oxygen on epitaxial growth and etching was studied, in conjunction with the nanometer-scale film morphology. Addition of oxygen to the hot-filament reactor had similar effects for growth conditions containing 0.5% or 1% methane in hydrogen. Growth rates at lower temperatures increased relative to samples grown without oxygen, proceeded through a maximum, and then decreased until etching was observed at high temperatures. Increased etching of diamond and non-diamond carbon was also observed for hydrogen with oxygen than for hydrogen alone. Oxygen addition improved the crystallinity of CVD diamond films deposited on silicon, as characterized by scanning electron microscopy (SEM). Without oxygen such films had polycrystalline features with relatively smooth (100) and rather rough (111) facets--with oxygen these films had both smooth (100) and (111) facets. Growth rates for diamond (100) and (111), with and without oxygen, were measured simultaneously using in situ Fizeau interferometry. The ratio of the two growth rates was then correlated with the nanometer-scale morphology, characterized by atomic force microscopy (AFM). Oxygen addition affected the (100) growth rate only; (100) epilayers were smooth for growth without oxygen but contained defects and penetration twins for growth with oxygen. The (111) epilayers from growth with and without oxygen were highly defective. Single-crystal diamonds, with and without CVD epilayers, and natural and synthetic diamond powders were treated in hydrogen plasmas, and examined by AFM and SEM. Evidence for a possible role of diffusion of surface species during diamond growth was observed.

How to Gain Power
Power is the most relatively objective measure of your account's strength, and as a result, gaining power is one of the primary goals while playing Mobile Strike.
Gaining power can be done in multiple different ways.
Methods of permanently increasing your power include:
Base missions are completed when the player completes some sort of assigned task, such as building an oil well and leveling it up for the first time. A base mission is awarded each time you complete something assigned by Mobile Strike, including constructing buildings, completing research, and so on. They can be claimed, or completed in the lower left of your base view. Each one adds commander XP and power, typically according to the difficulty of the mission. Players often wait until they level up their Headquarters to claim the missions so that they can maximize the XP bonus from each one once they have a higher level Hall of Heroes. This is done because the XP bonus conferred rises as the Hall of Heroes rises in level.
-Increasing Your Commander Level
Increasing your commander level can be done by earning experience points (XP). XP can be earned by battling with your commander present (either attacking or defending), completing research, base missions as mentioned above, completing research, attacking rebel targets, and completing base missions. The power from your commander can be taken away if he or she is eliminated, but this loss can be negated if you resuscitate him or her using a Medical Kit. Using a Medical Kit will save your power, and all of your Commander XP. So in a way, it is permanent power gained, but also could be considered temporary if you're splitting hairs.
Completing research adds power and can unlock more troops, traps, increase resource production, and many other things. It cannot be reduced or taken away. As mentioned above, completing research also awards XP for your commander.
Methods of temporarily increasing your power include:
Once built, buildings add power on their own, as well as triggering the completion of a base mission the first time you construct them. The power awarded (aside from the completed base mission) can be removed by deconstructing the building, however.
-Training Troops and Traps
Sort of self-explanatory. The more troops and traps you train, the more your power will rise. If the troops are killed or injured, or your traps are destroyed, your power will drop accordingly. If you heal any injured troops, your power will rise according to how many/what type you heal.

(25) How to suppress anger by reflecting on the attributes of the Bodhisatta
If anger is not yet abated or subdued
by reflection as stated in the foregoing, it should be suppressed by
reflecting on the noble qualities or the attributes of the Buddha in
his various states of existence previous to attaining Buddhahood.
The manner of reflection is:
"Oh, noble Yogi, the Buddha's disciple! Your Teacher, the Lord Buddha, in his capacity as a Bodhisatta, i.e. in his existences prior to attainment of his Enlightenment, for a period of four Asankheyyas (aeons) and a lakh Kappas while relentlessly exercising the virtues required of a Bodhisatta to accomplish the paramittas (perfection), had practised forbearance or patience without polluting the mind with anger even against all sorts of murderers who were his enemies. The way of practising patience is illustrated in the Visuddhimagga beginning from the story of Silava as an example. But now we shall cite an example of practising patience that can be found in the Khantivadi Jataka story.

Futures Market Expiration Dates
Futures markets (e.g. the Euro to US Dollar futures market) are traded using futures contracts, which are divided into several (usually four or more) contracts throughout the year. Each of the futures contracts is active for a specific amount of time, during which it can be traded, and the contract then expires, and can not be traded any more. The date upon which a futures contract expires is known as its expiration date, and the expiration dates are fixed for each futures market by the exchange that provides the market (e.g. the CME Group for the Euro to US Dollar futures market).
Standard Expiration Dates
There are four expiration dates which are considered the standard futures market expiration dates. The four standard expiration dates are the third Friday of every third month, which in 2011 (next year) will be as follows:
 - March 18th
 - June 17th
 - September 16th
 - December 16th
The standard expiration dates apply to most of the stock index futures markets (e.g. the Nasdaq 100 futures market), most of the stock index options markets (e.g. the S&P 500 options market), and some of the individual stock options markets, and are known as triple witching Friday because of the three types of markets that are expiring.
Additional Expiration Dates
There are also several expiration dates that are equally as important, but they are not known as the standard expiration dates (or as triple witching Friday). The additional expiration dates can be any day of any month, such as the Monday before the standard expiration dates, which is the expiration date for most of the currency futures markets (e.g. the Euro to US Dollar futures market).
Finding The Expiration Dates
The expiration dates for each futures market are provided by the contract specifications for each futures market, which are provided by the exchange that provides the market, and are usually available via the exchange's web site (e.g. _URL_ etc.).

Deadlines are a ubiquitous feature of lawmaking in contexts such diverse settings as agency rulemakings, federal appropriations, and international negotiations. Despite the expectation that these deadlines will drive conflicting parties toward agreement or overcome bureaucratic inertia, their impact on decision making is mixed, often producing only modest improvements in speed, and perhaps sometimes none at all. On the downside, deadlines can sometimes reduce the quality of decisions or encourage brinksmanship when missing a deadline would have draconian consequences. If there is a case for deadlines, then, it is an uneasy one. Game theory suggests some possibilities for to increase the effectiveness of deadlines as action-forcing strategies, such as improving information sharing between actors and providing enforcement mechanisms for negotiated outcomes.


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.


text: How could social scientists and cultural theorists take responsibility in engaging with science? How might they develop an experimental sensibility to the links between the production of knowledge and the production of existence or forms of life? Critically outlining key fields in the social and cultural studies of science, we interrogate a number of approaches to these questions. The first approach tries to make sense of how science operates in relation to economic, political and cultural forces. The second analyses science as a form of embodied work or practice. The third engages with science as collaborative-collective elaboration of events, ranging across cultural theory, contemporary art and participant ethnographies. This outline sketches a vector of responsibility across this diverse range of engagements, suggesting that contemporary movements between science and other knowledges constitute ethical and political imperatives.

Motoo Kimura (13 November 1924 – 13 November 1994) was a Japanese mathematician and biologist. He was known for introducing the neutral theory of molecular evolution in 1968. "Calculating the rate of evolution in terms of nucleotide substitutions seems to give a value so high that many of the mutations involved must be neutral ones".
He became one of the most influential theoretical population geneticists:
Motoo Kimura's research contributions can be divided into two parts. The first is a series of papers on theoretical population genetics, the quality and quantity of which place him as the successor to the great trinity, R.A. Fisher, J.B.S. Haldane and Sewall Wright. The second is his neutral theory, the idea that the bulk of molecular evolutionary changes are driven by mutation and random chance, rather than by natural selection.
Kimura was heavily influenced by Sewall Wright; the main distinction being that Wright was mainly interested in populations, whereas the core of Motoo's work was in changes at the molecular level. Modified versions of Kimura's ideas are still in use today.
In 1992, Kimura received the Darwin Medal from the Royal Society, and the following year he was made a Foreign Member of the Royal Society.

Introduction: Active learning methods have accumulated popularity due to improved results in knowledge acquisition as opposed to passive learning methods. For surgical resident physicians with limited training opportunities outside of the operating room due to time constraints, virtual reality (VR) is a relatively inexpensive and time-efficient active training method for procurement of surgical skills. We conducted a simulated intramedullary nailing (IMN) of a tibia to demonstrate VR training programs as a more effective modality of learning orthopedic surgical techniques compared to passive learning tools such as a standard guide (SG) through trained novice medical students performing a SawBones simulation of intramedullary nail fixation.
Materials and methods: First and second-year medical students without prior experience of procedure were recruited and randomized to SG or VR training. Participants were observed performing simulated tibia IMN procedure immediately after training and evaluated by a blinded attending surgeon using procedure-specific checklist and 5-point global assessment scale. Participants returned after 2-weeks for repeat training and evaluation.
Results: 20 participants were recruited and randomized into VR (n = 10) and SG (n = 10) groups. All 20 participants completed the first phase and 17 completed the second phase of the study. Aggregate global assessment scores were significantly higher for VR than SG group (17.5 vs. 7.5, p < 0.001), including scores in all individual categories. The percentage of steps completed correctly was significantly higher in the VR group compared to the SG group (63% vs. 25%, p < 0.002). Average improvement between the first and second phases of the study were higher in the VR group compared to SG group across all 5-categories of the global assessment scale, and significantly higher for knowledge of instruments (50% vs. 11%, p, 0.01).
Discussion: VR training was more effective than a passive SG in our model of simulated tibia IMN for novice medical students. Virtual reality training may be a useful method to augment orthopedic education.

HSBC Swaps Paper Records for Blockchain to Track $20 Billion Worth of Assets
According to Reuters reports, HSBC aims to move $20 Billion worth of assets from paper to a Blockchain Custody platform by March 2020. The platform may eventually move up to $50 billion in value of assets. The new platform is known as Digital Vault. Previously, HSBC had processed a Yuan-based Letter of Credit using the Voltron platform, a R3's Corda blockchain platform solution. Voltron is the open industry platform to create, exchange, approve, and issue Letters of Credit on Corda. Letters of Credit are said to be involved in between 11 to 15% of all global export transactions, racking up over $1 trillion each year.
A Letters of Credit (LC), also known as a draft, a documentary credit, or bankers' commercial credit, is a letter from a bank guaranteeing that a buyer's payment to a seller will be received with a specified sum in a specified currency and provided the seller meets precisely-defined terms within a fixed time frame.
When the buyer is unable to make the payment, the bank will cover the full or remaining amount of the purchase. An LC is one of the most common payment methods available in international trade, as in such contexts where banking channels are used for payment between parties who may not trust each other. An issuing bank sends an issued LC to a confirming bank that will undertake to pay the exporter according to the terms of the LC. The following diagram shows a simplified example of an LC process, although a real transaction could be much more complicated:
The LC process is inefficient and typically time-consuming, as it depends on complex financial and administrative operations involving multiple actors. Blockchain technology can help to simplify the process by sharing financial data and documentation through a secure network that requires no third-party verification. Based on the report, the global finance company BBVA was able to reduce the time required to send, verify, and authorize an international trade transaction. The process, that usually takes from around 7 to 10 days, can be reduced to just 2.5 hours by using the blockchain.

Najdi sheep
From Wikipedia, the free encyclopedia
 (Redirected from Najdi (sheep))
Jump to: navigation, search
Najdi sheep in Unaizah, Saudi Arabia
The Najdi or Nejdi is a breed of domestic sheep native to the Najd region of the Arabian Peninsula. Though it is primarily raised in Saudi Arabia, Nadji sheep are also present in Kuwait, Jordan, Oman and Iraq.[1]
The Najdi has a distinctive appearance that has even been celebrated in Saudi "sheep beauty pageants" not unlike livestock shows and sales in the West.[2] They are a very tall breed, averaging 76–86 centimeters (30–34 inches) in height at the withers.[1] They have long, Roman nosed faces with drooping ears. Ewes are polled and rams may be either polled or have scurs. They are generally black with white faces and white on the legs and tail. Top Najdi ewes can sell for 20,000–30,000 Saudi riyals (US$5,300–8,000), while rams which can sire many more offspring can fetch hundreds of thousands.[2]
Najdi are highly adapted to life in desert conditions, though it is less drought tolerant than some breeds, such as the Awassi.[3] [4] Though its meat may be consumed locally, it is especially valued for its milk and long, straight wool.[4]

Employee onboarding: identification of best practices in ACRL libraries
Purpose ‐ The purpose of this paper is to identify best practices of employee onboarding, the process by which a new employee is introduced to an organization and its vision, mission, and values. Design/methodology/approach ‐ Researchers requested that members of the Personnel Administrators and Staff Development Officers Discussion Group of the Association of College and Research Libraries (ACRL) share documents related to employee onboarding and three researchers independently reviewed the documents. The collected documents were compared to the socialization model proposed by Raymond Noe, including the detailed aspects of the organizational phase and the key components identified in the best practices literature. Findings ‐ In total, 17 institutions submitted documentation for review. All institutions discussed at least one or more of the key areas identified in the socialization process. Every institution in the study included a discussion of job expectations and evaluation criteria (100 percent); ten (59 percent) discuss mission, vision, and values; however, topics such as culture (five or 29 percent) and politics (one or 6 percent) were infrequently covered. Onboarding programs varied in length (one week to more than six months). Check lists were the most common tool used to manage the onboarding process. Other notable topics covered include dealing with change, understanding the team-based environment, diversity, library awards and library fundraising. Research limitations/implications ‐ Because of the limited number of documents examined in this study, the research results may lack generalisability. Therefore, researchers are encouraged to test the proposed propositions further. Practical implications ‐ Moving from a traditional new employee orientation model to a best-practices onboarding model will require HR professionals to conduct an internal assessment of the current program. Originality/value ‐ Due to the high cost associated with recruiting new employees, the need for new employees to be fully functional and engaged as soon as possible, and the need to communicate performance indicators, the need to share best practices is important.

Make this Star Garland for a really effective home made Christmas Decoration which you can drape around a Christmas tree or use as a wall hanging.
Use glittery or shiny paper for a real Christmas feel.
- Coloured paper
How to make a Star Garland…
- With the paper held landscape, cut strips of paper 1-2cm wide.
- Fold each strip in half and half again.
- Unfold and cut the strip along the creases so you have four short lengths of paper.
- Hold two pieces of paper together and staple the ends together.
- Repeat with the other two strips of paper.
- Open up each of the strip couples and attach together with some more staples.
- Repeat steps 2-6 with all the strips of paper.
- Attach the stars together into a garland using tape or a stapler and hang wherever you would like a decoration for Christmas.
- When folding your paper into four and cutting, do several strips of paper at a time to make the process quicker.
- If you use glue instead of a stapler, make sure the glue is dry before attaching the stars together.


Focus Group:
Strengthening and Diversifying the Clergy
In order to have a stronger and sustainable Clergy, it must be diverse. Our goal is to include all people, men and women with diverse backgrounds, as equal partners in the Church, as they already are in the eyes of God. Here are some of the questions this Focus Group is exploring:
 - How can we include women in highly visible diocesan-wide leadership roles? How can we increase women's voices and their votes in matters of church governance?
 - How can we address the diminishing number of clergy and seek a way forward by encouraging women and men called to serve in the Church?
 - We aim to promote discussions between laity and clergy about women serving in the diaconate and married men and women serving as priests.
 - How do we work with the diocese to better understand the attitudes of the laity about a variety of church issues, and how the laity can help support the priests in every parish, through surveys and active listening sessions?

Load Balancing SQL with NetScaler
Scaling the Data Tier with Citrix NetScaler DataStream Technology
Native support and intelligence of SQL transactions is the key to extending the scalability, availability, and security benefits that the ADC brings to the web tier to the data tier, as noted in Sunil Potti's blog. Similar to the benefits of HTTP load balancing, a data tier load balancer should provide these key benefits:
 - A native SQL proxy like solution to perform SQL connection management and offload for database scale up scenarios to increase SQL connection limit.
 - A TDS protocol and SQL transaction intelligent load balancer that can accurately monitor backend server status including slave replication backlog to
 optimally distribute load in database scale out setups.
 - High Availability that can address both Master/Master and Master/Slave replication deployments to complete the database scaling solution. Both scaling approaches also need advanced, clustering-like automated IP failover for lower cost high availability with commodity hardware.
 - Database security encompassing transaction activity logging tied to user logins for compliance purposes to be generated from a central location to
 simplify record management.
NetScaler DataStream Technology
Leveraging its expertise in web applications, NetScaler with DataStream technology is the first ADC that justifiably addresses data tier challenges.
With DataStream technology, NetScaler introduces the industry's first "true" load balancer for data that offers native SQL protocol, data format and
transaction support for scaling database infrastructures. Structured Query Language (SQL) which is the de-facto data format, TDS (Tabular Data Stream) and Oracle MySQL, protocols that are widely deployed, are natively parsed and interpreted in NetScaler's high speed processing engine, providing all of the
advance policy framework available to act on data connections and transactions. Applying all of the same HTTP acceleration technologies to SQL, NetScaler is able to provide the same benefits to the data tier, such as SQL Connection Multiplexing, SQL Load Balancing, SQL Content Switching, SQL Health Monitoring, Automated Failover and Security.
SQL connection multiplexing: NetScaler's SQL transaction intelligence enables NetScaler to act as a SQL proxy and terminate SQL connections from both
client and server. Client to server connection multiplexing ratios of 50:1 or more is achievable depending on the application, number of unique database user
logins and character sets in use. SQL Load balancing: Armed with SQL transaction awareness, NetScaler can switch one client's many SQL transactions in a single TCP connection to several different servers. This delivers more optimal load balancing of SQL traffic since the load distribution is more granular when compared to a TCP load balancer.
 - SQL Content switching (read/write split): NetScaler can interpret SQL transactions and decipher between "select", "drop", "insert", "update" and other SQL statements and perform a split between read and write transactions. Splitting the reads and writes simplifies application server deployments by offloading the decision making and policy enforcement to NetScaler.
 - SQL Health monitoring: NetScaler intelligently load balances SQL requests, by selecting the database server that will return up-to-date data the fastest at the time of the request and sending the read request to only that server.
 - Automated IP failover: NetScaler's Virtual IP address solution is based on automated IP failover implementation where the virtual IP is assigned to the master node is switched over to the secondary node upon detection of heartbeat/monitor failure.
 - Security: NetScaler can apply granular user access policies to each database user. It also provides a consolidated log of all SQL transactions and user
 accesses for complete visibility, without taxing the database server. SQL protocol validation is also available with advanced Policy Infrastructure (PI)
 regular expressions.
As the industry's first SQL aware load balancing solution, NetScaler addresses the scaling and availability needs of the data tier, leveraging its
HTTP ADC technology for the web tier. NetScaler's SQL connection multiplexing scales connection limits for database scale up, native SQL load balancing
optimizes database scale-out, SQL transaction logs simplifies database security and replication aware monitors with Virtual IP based failover enables
cost-effective high-availability.
Combine SQL with Netscaler and you have a perfect match =o)

During the Gold Rush boom, in San Francisco's early years, the city suffered six major fires. Because these fires destroyed 25 to 50% of the town, they were called Great Fires. As San Francisco quickly rebuilt herself rising from the ashes of those fires, the Phoenix became the symbol of the city.
On April 18, 1906, because the Richter magnitude of the earthquake was over 8.0, it is classified as a Great earthquake. In 1906, when half the city was lost, the earthquake caused 20% of the damage and the fire caused the other 80%.

Mobile operators are all set to turn into dump pipes, with GSMA predicting their data revenues overtaking voice revenues globally by 2018 as we move towards a fully connected world. A surge in demand for connected devices and machine-to-machine (M2M) communications is driving this trend, transforming the "socioeconomic future of people" in both developed and developing countries.
In developed countries:
- mHealth could save $400 billion in healthcare costs
- Connected cars could save one in nine lives through emergency calling services
- mEducation can reduce student drop-outs by eight per cent or 1.8 million children
- Smart metering can cut carbon emissions by 27 million tones – the equivalent of planting 1.2 billion trees
In developing countries:
- mHealth can help save one million lives in sub-Saharan Africa
- mAutomotive will improve food transport and storage, which could help feed more than 40 million people annually – equivalent to entire the population of Kenya
- mEducation can enable 180 million students to further their education
- Intelligent transport systems could reduce commute times by 35 per cent, giving commuters back a whole week each year
Before I let you go, it's worth adding that during last year, Japan became the first country where data revenues exceeded voice revenues, due largely to the availability of advanced mobile broadband networks and a higher adoption of the latest smartphones, tablets and connected devices.
And you can learn more about this from the full "Connected Living" report, available from here.

Estimating the girth of fish by applying an elliptic model
- A new method for estimating the maximum girth of roundfish is proposed as illustrated; this is based on an elliptic approximation of the cross sections of the fish body. Results derived from a small sample horse mackerel, Trachurus trachurus, suggest that maximum girth estimates based on the elliptic model are more precise than the values estimated by applying a conventional method.

The tensile strength of copper as defined by the Young's modulus is 129.8 gigapascals, (129.8 GPa). This number is at the upper end of the range, meaning that copper is a very ductile material and can tolerate being pulled into very thin wire without breaking.
This high ductility is due to the electron arrangement of the copper atom, which has a filled d-shell with one s-orbital electron above it. This makes its metallic bonds relatively weak. Copper shares this property with certain other metals such as silver and gold.
Copper's ability to be pulled into thin wire makes it ideal for electrical wire and jewelry. Copper is soft, however, and is often alloyed with other metals such as zinc to provide strength.

dc.description.abstract Haitians in the United States represent the fourth largest immigrant population from the Caribbean. As in the case of many immigrant populations, Haitian immigrant adaptation has been challenged by social, political and economic factors, and as a result they have had to seek legal, health, and social services. According to the literature, help-seeking behaviors among Haitian immigrants have been associated with traditional indices of socioeconomic status, namely education, occupation, or income. This study takes a more in-depth look at the influence of social class by approaching it as cultural construct in the context of historical patterns of Haitian immigrant incorporation. Most Haitians arrived during the latter half of the 20th century in four successive waves, the 1957, 1970, 1980 and 1991 wave. Each of these waves of Haitian immigration represented a distinct context of departure and social class composition. A qualitative approach was used to obtain rich information on the role of help-seeking in the immigration and incorporation experience of Haitians from the perspective of immigrants who arrived during the four distinct waves of immigration. Individual and focused group interviews were conducted in English, Creole, and French with a purposive and snowball sample of 43 Haitian immigrants currently living in south Florida. Using a grounded theory approach, the analysis generated six categories related to the Haitian immigrant experience: orientation at time of arrival, establishment of social connections, issues of trust, generational effects, cultural constructs of social class, and perspectives on the help-seeking experience. Key findings emerged that identified the importance of social connections in Haitian help-seeking behaviors in the context of a complex Haitian social class construct imbedded in historical, political, and economic positioning. Specifically, across all immigration waves, regardless of social background--from the highly educated doctor who arrived in the 1950s to the rural peasant who arrived in the 1990s--Haitian immigrants identified an individual of Haitian descent residing in the United States on whom they relied for assistance in obtaining resources. This system of social connections reflected the social constructs of class existing in Haiti and remained a significant factor in Haitian immigrants' help-seeking behaviors during resettlement.

New Study Sheds Light On How T-Rex Arms Were Used
A new study takes a close look at how Tyrannosaurus Rex's arms would have functioned, a question that has been hotly debated for years. By studying the limbs of two distant modern relatives of the extinct theropod, the researchers found that its tiny limbs were far more flexible than previously believed. The research was presented at a recent meeting of the Society of Vertebrate Paleontology.
T-Rex roamed the Earth between 65 million and 80 million years ago. It's tiny limbs with sharp claws has baffled scientists pondering their function and usefulness. Some believed that their arms didn't do much of anything. The new research disputes this.
This latest study researched the range of movement to determine the usefulness of the arms. For comparison, the researchers studied the limbs of the American alligator and the domestic turkey. The study suggested that complex elbow joints allowed for a range of motion far greater than a mammal could achieve.
The scientists used a technique called X-ray Reconstruction of Moving Morphology (XROMM) to examine the ulna and humerus of the modern animals. This allowed them to analyze the movements made possible by soft tissues, which are often lost in the fossilization process.
The researchers said that it was surprising to see how much the forearm bones could rock side to side at the elbow. That is not a range of movement generally seen in mammals. This expanded movement at the elbow would allow alligators and turkeys to turn the palm of the hand inward and upward like we do.
The team concluded the T-Rex most likely used its arms to hold prey in place or pull it closer. Its arms could have been used to keep prey at the perfect biting distance for its powerful jaws.
Members of the team commented in an interview, "They may have been able to rotate the palm of the hand inward and upward in such a way that the palm would face the chest when the elbow was flexed. We might speculate that such a movement could allow some theropods to bring prey in close for a bite."
