The Order of Things – What College Rankings Really Tell Us by Malcolm Gladwell
The main argument of this article is that it doesn't matter who comes out first place in a certain ranking, it all depends on who's doing the ranking and
on what variables the ranking is taking place. Malcolm Gladwell believes that a ranking can be heterogenous (diverse in content), as long as it doesn't
try to be too comprehensive (including all or nearly all aspects of something). He also believes that a ranking can be comprehensive as long as it
doesn't try to measure things that are heterogeneous. Also even if the ranking is trying to be both heterogeneous and comprehensive at the same time,
it'll only work properly if the subjects being ranked are ... Show more content on Helpwriting.net ...
It requires someone to make a surmise about the intentions of the deceased at the time and although in some cases that is easy, in most cases
there's ambiguity. Different coroners and different cultures vary widely in the way that they choose to interpret that ambiguity. A suicide may be
called a suicide, a homocide, an accident, or left undetermined, depending on the culture the deceased followed. As a result, nobody can truly know
whether suicide rankings are real. This article explains in finite detail how if the variables on which a certain ranking is based on is changed, the
ranking itself will also change especially if the ranking is both heterogenous and comprehensive as many variables are being taken into account at
once. Another aspect that can change rankings is who the rankings is done by as everyone has their own opinions and thoughts and depending on
what that specific person thinks or feels about a certain subject will alter how they will rank a certain subject compared to somebody else. For
example if somebody was told to rank colleges based on their 'graduation rate performance', the school with the highest graduation rate will be ranked
as first. On the other hand if those same colleges were ranked based on tuition fees, in this case the variable the ranking was based on has changed,
there is a possibilty the school ranked first for the highest graduation rate would be ranked

2. Testing the Difference Between the Respondents Demographic...
Testing the difference between the respondents demographic groups As mentioned in chapter 4: table 4–3, there was a very different between the
number of respondents within some demographic groups, e.g. the gender groups compromised 185 males and 25 females and similarly, the academic
background groups compromised 3 high school, 185 graduate and 85 postgraduate holders. Therefore, generalising the results of testing the difference
between the means of these groups may be invalid and meaningfulness. However, it could give general indicators about the opinion of each group
regarding the performing the SECI and innovation processes within the Egyptian banks.
In this term, there are two methods to test the difference means between groups ... Show more content on Helpwriting.net ...
In the other hand, the One–way ANOVA test is used to test whether three or more groups means are different. This test is suitable for testing the means
difference between the years of experience groups (≤ 5, 6–10, 11–15, 16–20 and >20yrs), between the academic background groups (high school,
graduate and postgraduate) and between the job title groups (junior, senior, head of department, auditor, vice manager and manager)
Independent t–test results
The t–test can be used to test whether two groups are different. The independent t–test is used when there are two experimental conditions (e.g. male
and female or public and private banks) and different participates have been used in each condition (e.g. SECI and innovation processes). Independent
t–test table yielded by PASW normally mentions two rows for the teststatistics: one row is labelled Equal variance assumed, while the other is
labelled Equal variances not assumed. Which row is considered is based on the significant of Levene's test for Equality of Variances. Therefore, if the
Levene's test is significant, the Equal variances not assumed row will be used for the t–test. The significant of this difference is based on the
significant of the t–test. That is, if this test is significant, it could be included that the difference between the means of these

3. Verbal Reaction Times Experiment Essay
This report aimed to replicate Stroop's (1935) experiment. Using the repeated measures design and a sample of 20 students, differences in verbal
reaction times on two tests were observed. The one–tailed hypothesis predicted that it would take longer to say words in the Cc, this is the conflicting
condition where the colour of the word differs from the colour that the word describes. It was found that, using the t–test for related data, this
hypothesis could be accepted as the obtained value was much greater then the critical value. It can therefore be concluded that visual interference does
affect people's verbal reactions.

However, automatic processes are hard to amend once learnt. Kahneman proposed his capacity/resource allocation model in 1973 (see Figure 1):
[IMAGE]
Figure 1
This model could provide an explanation for the Stroop Effect as the visual interference of the conflicting colour could be described as a momentary
intention (a voluntary shift of attention). This is because the participant has to force his/herself to read the word and not say the colour of it. This
therefore means that, according to Kahneman, the central processor has trouble deciding between tasks (in this case, between reading the actual word
or the colour of it). This could be an explanation for the expected delay in the condition where the colour of the word is different to the colour that the
word describes.
Aims and Hypotheses
Aim
The aim of this report is to replicate Stroop's original (1935) experiment.
4. Alternative Hypothesis
Words that are coloured in conflicting colours to that which the text describes (conflicting condition, Cc) will take significantly longer to process than
words coloured in the same colour that the text describes (similar condition, CS). This is a one–tailed (directional) hypothesis.

Nevertheless, these changes in the instrument point in the right direction, improving some of the deficiencies mentioned earlier. The new
measurement, for example, assigns more weight to criteria such as pluralism and media concentration. The questionnaire section on "Pluralism and
editorial independence" includes, for the first time, the following questions, all on a scale from 1 to 10.:
D.2 – Do media reflect the range of opinions among members of the public?
D.3 – Do public media provide coverage of and access by all political currents?
D.4 – Is investigative journalism developed enough to uncover matters of significance?
D.9 – To what extent do radio and television stations with the largest audiences present independent and critical news?
Question D.11 on media concentration is more sensitive than before, since respondents are asked to evaluate it from a scale from 1 to 10. Moreover,
another question is included to assess economic concentration in general and possible conflicts of interests:
D.12 – What proportion of general–interest media is owned by companies with other interests in non–media sectors of the economy? (5 if 50%; 10 if

on medicinal uses of the indigenous plants have been described after gathering information from general local people and experienced aged rural
folk. The research population consisted of 674 people, including residents of the five villages. According to the study and collection of data and
characteristics of population, the sample size was determined using the equation Cochran (214 = n). A total of 214 inhabitants from 5 villages were
interviewed. The randomly selected respondents of different ages from about 40 years and above were interviewed in local language, that is,
Mazandarani. A semi structured questionnaire was used to elicit information from the resource persons using standard methods Information on local
name of the plant, plant parts used for curing disease their recipes and mode of administration were recorded. Plants collected during the surveys were
identified with the help of flora.Cronbach 's alpha coefficients were calculated for different parts of the questionnaire that the total value of 0.78 was

14. Estimating The Mixing Density Of A Mixture Distribution
Estimating the mixing density of a mixture distribution remains an interesting problem in the statistics literature. Stochastic approximation (SA)
provides a fast recursive way for numerically maximizing a function under measurement error. Using suitably chosen weight/step–size the stochastic
approximation algorithm converges to the true solution, which can be adapted to estimate the components of the mixing distribution from a mixture, in
the form of recursively learning, predictive recursion method. The convergence depends on a martingale construction and convergence of related series
and heavily depends on the independence of the data. The general algorithm may not hold if dependence is present. We have proposed a novel
martingale decomposition to address the case of dependent data.

normally distributed or not, this was the issue that the research question and hypotheses focused on.
H1 Family poverty is skewed compared to a normal distribution
H2 Family poverty is not skewed compared to a normal distribution
The Chi–squared test has certain requirements in terms of the minimum expected population for each category. The data did not meet these criteria,
meaning that the chi–squared test in this circumstance would be inappropriate. To avoid such issues, the nonparametric Kolmogorov–Smirnov test was
used in preference as it has less rigorous data requirements..
The positive skewness values for FP89 (1.285) indicate that the sample is positively skewed compared to a normal (Gaussian) distribution, with a long
right tail. The kurtosis value is 2.013, compared to a normal distribution which would have a Kurtosis value of 0.00. Thus, the test has indicated that the
distribution of both samples is substantially more peaked than would be the case for a normal sample distribution, this means that the null hypothesis
should be rejected and thus that family poverty is skewed compared to a normal distribution.

Introduction
Perhaps one of the most difficult managerial decisions in the 21st century is the decision to make a decision. Analysis paralysis, endless meetings, and
corporate structure have made it painstakingly difficult to come to any real conclusions. So when the Chief Financial Officer, Bruce Berman, of
Bloomindale's was tasked with decision to implement ProfitLogic's Pricing Optimization (PO) system, he called upon Daniel Gabbay, an analyst in the
finance division, to make sense of the numbers and guide his decision making process. Berman was considering implementing a PO system to quantify

Fortunately, performing these non–parametric techniques for just a few of the possibilities would give insight as to whether we were on the right track
and the time spent analyzing the data in this manner could prevent a long arduous path to an erroneous conclusion. Statistics is a science, and like all
science, it requires testing. And after this initial testing and concluding that the PO System does increase revenue–this assumption is perfectly
reasonable to make since ProfitLogic is still in business–we could then build a model to determine by how much revenue will be increased and what
the payback period might be.
Building the Regression Model
As previously mentioned, no analysis is given for the regression model, so we shall at least attempt to ask the appropriate questions needed to make
an intelligent decision. We begin by looking at the structure of the regression model prior to performing the diagnostic procedures. First, we must
understand why the consultants chose to model the revenue in the markdown period as a product of the observed performance in the regular period,
the PL effect, Department effect, the promotions effect, and a constant. If there are no PL effects, department effects, or promotions effects, then the
revenue is simply a function of the overserved performance in the regular price period. This is logical, as adding in an "effect" simply scales the
revenue.

24. Transcranial Magnetic Stimulation
Transcranial magnetic stimulation (TMS) might be an appropriate alternative treatment Because of its simplicity, Single TMS pulses have been used as
the noninvasive and painless method for stimulating the brain of intact conscious human subjects through the scalp [4]. Repeated applications of single
TMS pulses (rTMS) can sometimes elicit long–lasting changes in the excitability of the corticospinal tract, M1, and spinal cord structures, significantly
improving the sensory and motor function in the patients with motor disorders [5].
Applications of rTMS to the motor cortex at appropriate stimulation intensity can enable recording of motor evoked potentials (MEPs) from the
muscles of the contralateral extremity. MEP amplitude can be affected... Show more content on Helpwriting.net ...
According to the results of this study, latency and MNCV were more enhanced in the experimental group than the control group after the intervention.
Active rTMS was more effective than sham rTMS in improving motor recovery.
According to another study, rTMS could reduce motor improvement in SCI. It is possible that motor score improvement and amelioration of spasticity
with rTMS in SCI can be induced through enhancement of descending corticospinal projection and reduction in corticospinal inhibition [11].
Using a sample of 17 SCI AIS D level patients, Benito et al. [12] applied 20 Hz high–frequency rTMS to an experimental group consisting of seven
patients, and applied sham rTMS to the control group consisting of ten patients, for 15 days each and reported that the experimental group showed
significant improvement in modified Ashworth scale (MAS), 10 m walking test (MWT), cadence, step length, and timed up and go test (TUG)

25. Evaluation Of A Juvenile Drug Court Program
Research Article Analysis In today's society there is an enormous amount of research being conducted throughout the world. A great many of those
studies are occurring on Universities and campuses, in this paper, analysis of one such study will be reviewed. The article is an evaluation of a Juvenile
Drug Court Program in Lexington, Kentucky. The data that is coming from the Bureau of Justice suggests that juvenile courts process a higher volume
of cases today than at any time in the past (Hayden, 2012) These statistics represent the trend in persistently high rates in use of illegal substances
among adolescents in the United States and subsequent juvenile court involvement. [The purpose of this study was to examine these outcomes in
criminal offending and substance use for one of the first juvenile drug courts (JDC) in Kentucky, implemented in 2003 located in Lexington, Fayette

(Hayden, 2012). The concept of a drug court was conceived in Miami–Dade County, Florida by Chief Judge Gerald Wetherington in 1989. That court
was for adults, and the idea was to provide alternatives to incarceration and probation by affording offenders opportunities to get treatment with

INTRODUCTION Violations in traffic laws are very common in a highly populated country like India. The conditions are even worse in metro cities
like Delhi, Mumbai Bangalore and Chennai. The accidents associated with these violations cause a huge loss to life and property.
Same is the case in Chennai. Being a metro city and a highly populated one also, has a lot of road accidents every year. Despite this the violations in
traffic laws do not reduce. A lot of people disobey the rules every day sometimes willingly and sometimes because they are forced to do so because of

Also it has a vast population which causes a lot of traffic on the roads. Knowing these factors help us to collect more accurate data because it enables
us to compare between different situations and make a better analysis. These factors can be identified as:
Overcrowded roads because of a large population, Maximum traffic is observed during office hours i.e. between 8.00–10.00AM and 5.00–8.00PM.
Therefore the maximum violations are also done during these peak hours. Are report includes study during both peak as well as non peak hours. One
another important factor is that since most of the offices are in the areas like Vandalur and Perangalatur, the maximum traffic is observed in these
areas. So these areas experience maximum breaking of traffic laws.
The violations mentioned in the report are:
Overloading of vehicles– it is very common in the case of two wheelers.
Not wearing helmets or seat belts is also a major rule which is not followed and is the cause of many deaths and serious injuries.
Drunken driving and speeding beyond a mentioned limit.
Driving in the wrong direction is one of the key violations.
Not obeying the traffic signals is observed mainly during the peak hours of traffic as everyone is in a rush to reach early.
Thus, these are the basis on which the report is based.

In the previous article, it was evident that awareness of one 's illness was linked to the better function outcomes and lower self–esteem and hope. The
explanation that was given for such findings was based on the concept that acceptance would impact on the outcomes in different ways depending on
the meaning that one attaches to the acceptance. In this case, variability will be evident depending on the extent that one accepts stigmatizing
ideologies and beliefs concerning mental illnesses. Unique from people with other psychiatric and mental conditions, schizophrenia individuals will
more often than not willfully contest or are unaware of what others think of them to be mentally ill. Taken fully, the phenomena was described as a lack
of awareness but showed a contradiction with some part of the results. From the results, it was concluded that acceptance of schizophrenia is highly
dependent on the meaning that the patient attaches to schizophrenia. In the article, it was believed that if one believes that the illness is an implication
that they cannot achieve some socially valued roles, and this could lead to hopelessness and demotivation of perseverance. Nonetheless, if the patient
does not share in the opinion thatillness can preclude the possibilities of satisfying life, then the patient's awareness of the condition will make them seek

The Academic ranking is one of the priorities in the society including the students, University, Higher education etc. However, there are some of the
advantages and disadvantages using academic ranking. More importantly, it is still useful because using this can be our basis in applying college
admission and the course we would like to take.

the URAP ranking were gathered from the Incites database of private analytic (Corap, 2016). At any rate, all the academic ranking must have done
the proper process for the judges to know that they are worthy of the ranking they are in. Moreover, the students who passed the criteria of being an

one is introduction, where the authors explain what results are reached and carefully introduce the readers to the structure of the article. In the next
section the hypotheses is derived. After that, section 3, the variables and the data is described. The tests begin from section 4 to section 6. In those
sections the authors use non–parametric tests, regression analyses and vector autoregressive specifications in order to reach their results. The last
section is the conclusion of the article, where the major findings are listed. The authors find that institutions prefer firms that pay dividends to ones
which don 't. Moreover, within dividend–paying firms, institutions are not attracted to high dividends. They also find a positive relation between
repurchases and institutional holdings. Their results also suggest that institutions prefer firms that repurchase regularly to firms that repurchase
sporadically. They don 't find evidence that an increase in institutional holdings in firms is followed by an increase in dividends or repurchases. Their

The aim of this study was to demonstrate that with Semantic Association training, participants would rank more word pairs correctly than participants
who did not receive any training. There were five hypotheses in this study. Firstly, it was predicted that the group who received Semantic Association
training (experimental group), would receive a higher, total score in the Ranking Pairs task, than the control group who did not receive any training.
This result was significant and did demonstrate that training did improve the way people associated word pairs.
Secondly the prediction that the experimental group would gain more points in the non–associated category was significant, and demonstrated that
after training, people tended not to incorrectly rank certain word pairs, which were not semantically connected through a synonym. The predictions that
the experimental group would gain more points when ranking indirectly and directly associated word pairs were not significant however. The final

The newly designed system follows 4 point scale instead of 13 point scale which made the manager task easier in evaluation.
Cons of Newly implemented PMS:
Some employees were reluctant to perform their duties outside the job as those responsibilities were not in the review system. So they preferred only
to work in the domains which were taken into consideration for their reward.
Some managers felt that the new distribution system to be very rigid. High performing team need to come up with the targeted number of achievers
even though they had many of them. On the contrary, the low performing team also had equal number of top achievers.
The new PMS uncovered some managerial dissembling. Because managers allotted 'Not Rated' ranking to new members and saved the higher rankings
for their veteran employees irrespective of their performance. Hence the new member in team might be de motivated.
Some managers were reluctant in differentiating between their employees and allow any unfamiliar person to evaluate them. Because of this true
performer might miss his/her rewards and incentives.
Some managers rotated the highest ranking between their employees from one year to the next. So the objective of developing new evaluation system

Abstract
Background: Low back pain patients with associated leg pain symptoms generally have a poorer prognostic outcome compared to those with localised
low back pain. Therefore, this study will investigate the difference in clinical outcomes associated with low back pain patients with and without
self–reported leg pain symptoms. This study will also address if additional co–factors such as age, sex, and occupation have an effect on the severity of
these clinical outcomes. The clinical outcomes which will be considered are pain rating, interference with active daily living (ADL) rating, anxiety
rating, depression rating and control of pain rating.
Methods: This retrospective cohort study compares adult low back pain patients with localised pain (n = 58) to low back pain patients with
self–reported leg pain symptoms (n = 54) who presented for chiropractic treatment. Patients completed the WIOC patient outcomes questionnaire as
baseline which consisted of the Bournemouth Questionnaire, recording responses from an 11 point numerical scale (NRS). Demographic information
was also collected. Differences between the two groups using the data collected from this questionnaire were calculated using the Mann Whitney U test.
Differences between age and sex were also calculated using the test used.

When seeking to determine additional information needed to know from the pollster, mainly my first task would be to inquire which hypothesis test
technique was utilized. Moreover, once that was known and established and the correct hypothesis test was used then it would be much easier to

upper–tailed test, or a lower–tailed test (Mirabella, 2011).
Additionally, when hoping to gain more information from pollsters in reference to support of voters in the election for the candidates, first and

7% for each year when the adolescent is older. This is also more severe for teenagers who do not have a positive background for physical activity.(3)
The World Health Organizationplans to reduce this figure by 10% by 2025.(4) Physical activity means activities that are carried out at idle times for at
least 30 minutes without interruption and are powerful enough to increase heart rate and respiration. Also, these activities lead to skeletal and muscular
activity, resulting in burning energy.(5) Sufficient physical activity for adolescents up to the age of 15–17 is at least 60 minutes of moderate to strong

Statistical data analysis plays a crucial role in the field of nursing. For this research paper, the focus is on the nonparametric test, T–test, and
correlation. So, before I proceed, let me provide the definition of these test. "Nonparametric tests are sometimes called distribution–free tests because
they are based on fewer assumptions (e.g., they do not assume that the outcome is approximately normally distributed)". (,"Boston University School of
Public Health " 2016, p. 1). The t–test is "a parametric statistical test for comparison of the means of two independent groups." (Kellar & Kelvin, 2013,
