transforms correlations among a set of observed variables into smaller number of factors, containing essential information about the linear inter-relationships among the original test scores (Kriegel, Kroger, Sander, & Zimek, 2011). Factor analysis is used in behavioral sciences, social sciences, and other applied sciences dealing with large quantities of data. In addition, factor analysis is subdivided into two major groups; exploratory and confirmatory. Cluster analysis on the other hand entails dividing a set of variables into groups; clusters with data in the same cluster being similar to each other as opposed to those in other clusters. Cluster analysis is mainly used in statistical analyses such as information retrieval, and bioinformatics. Just like factor analysis, cluster analysis has two subgroups; exploratory and confirmatory.

This problem is particularly acute among many impoverished African nations, although some African countries such as South Africa have made significant progress in developing their technological infrastructure in recent years (Tucker, Bachman, Klahr, Meza & Walters, 2008).
There have been some innovations in recent years, though, that may make the lack of a technological infrastructure in a given country of less import than in years past. For example, Hindman (2008) reports that, "Wireless services such as satellite systems may make the lack of technological infrastructure less of a factor" (p. 550). Nevertheless, there may be some country-specific cultural factors involved that hinder the widespread adoption of recent innovations in technology that will slow the development of a modern technological infrastructure. In this regard, Hindman adds that, "The emphasis on tradition rather than innovation, and the local orientations of rural citizens are likely to result in resistance to ideas imposed from…...

2008 Tenth Grade National-survey by Samhda/Icpsr
Substance Abuse & Mental Health Data
The study extracted data from the 2008 10th Grade National Survey SAMHDA/ICPSR. A five-factor exploratory factor analysis was conducted. Factors were labeled Marijuana, Alcohol, Weekend Alcohol, Graduation, and Periodicals. Total variance for the analysis was 88.467. The factor showing the highest percentage of variance was Marijuana. More variables loaded on Alcohol than other factors. Respondents did not perceive consumption of alcohol as high risk unless it was excessive, or excessive on weekends. Respondents reported the use of tobacco products as less indicative of risk compared to marijuana, which warranted higher disapproval. Overall, respondents consider themselves to be well informed and were confident about future opportunities for higher education.

Little information could be gathered about mental health issues for the 10th grade respondents in the available data from the survey. The data is not remarkable when compared to similar surveys about drug and alcohol use by high school students. That is to say that consumption of alcohol was not perceived as high risk unless consumption was excessive, or particularly, was excessive on weekends. Moreover, the use of tobacco products showed a different pattern of variance compared to marijuana, suggesting that marijuana is considered a more radical and risky drug -- and one that warranted higher disapproval. Overall, respondents consider themselves to be well informed and are confident about future opportunities for higher education. Future research should utilize question items related to mental health or from the DSM in this analysis as data regarding disordered thinking or school suspensions and difficulties with law enforcement are not included in the analysis.

The basis of these explanations is the chain-of-events theory of the causes of aviation accidents or incidents. HFACS categorization framework has four level sie. unsafe acts, organizational factors, preconditions for unsafe acts, and unsafe supervision.
In attempts to deal with human error, Human Factor Analysis and Classification System can be both proactive and reactive. The system can be proactive when used as a framework for predicting unsafe acts that contribute to aviation incidents or accidents ("Evaluation of the Human Factor Analysis and Classification System," 2008). In this case, HFACS helps in understanding skill-based errors, decision errors, and perpetual errors. The findings are then used to develop effective interventions that lessen the frequency and impact of such errors in aviation. On the contrary, the system can be reactive when used to predict higher levels human error within the hierarchy. This does not necessarily lead to the development of effective interventions but…...

By using two different data sets, this paper aims at improving two analyses conducted relating to leadership effectiveness and community policing studies. In addition, in the paper, reliability tests and factor analyses on some of the six scales of importance used in the Community Policing study are looked at in-depth. Besides, the analysis conducted by Dr. Eveland is re-evaluated in this paper.
Leadership Effectiveness
From the report conducted by Dr. Eveland, several multiple regression analyses were initiated to help determine the existence of any relationship among the nine scales to the dependable variable, Q75; overall satisfaction with the manager as a leader. When plotted in a graph, the variable moderately skewed toward higher values.
Additionally, a simple multiple regression of all the predictors showed a statistically significant relationship between predictors and variables (F = 19.33, df = 9, 462, p< 0.001, 2 = 0.27). Nevertheless, beta coefficients for individual predictors for…...

Entrepreneurial Intentions: Factors Influencing Intentions Among Arab Students
Factors Influencing Intentions among Arab Students: Entrepreneurship
Entrepreneurship can be defined as the process and mindset to initiate and develop economic activity. Studies have shown entrepreneurship to be a crucial driver of economic growth. This study sought to examine the factors that influence entrepreneurial attitudes among students in Arab countries. More specifically, it sought to examine the role of universities, role models, the entrepreneurial curriculum, and students' demographic characteristics in promoting Arab students' entrepreneurial attitudes. The study employed a quantitative research design, where data was gathered from a sample of 1500 undergraduate Arab students in government universities, and subjected to one-way ANOVA tests. Descriptive statistics (means and standard deviations) was used to draw additional conclusions from the gathered data. The results showed that Arab students acknowledge the role played by universities, the entrepreneurship curriculum, role models, and demographic variables in influencing their attitudes towards…...

Title: A Machine Learning Approach to Predicting Fatalities in Aviation Accidents: An ExaminationIntroductionSummary:The paper explores the deep use of machine learning algorithms to anticipate the occurrence of fatalities in aviation mishaps, concentrating primarily on the influence of human elements. The Aviation Safety Network (ASN) database forms the backbone of the study, from which models Model 1 and Model 2 are created, each investigating unique aspects of accident data.Model 1 engages in binary categorization, determining if a mishap led to fatalities (Fatality) or not (No Fatality), while Model 2 delves into the accidents that culminate in fatalities and prognosticates the level of fatalities (sparse, dense, full). The study makes use of three primary algorithms for data evaluation: andom Forests (F), Neural Networks (NN), and Active Learning (AL).Each algorithm was trained on a data subset (75% allocated to training and 25% for validation), and their validation was assessed through several metrics such…...

Moreover, the study compares the effect on human factors on different types of aircraft. The study also reveals the correlation between the anomalies and type of aircrafts.
Human factors cause of Aircraft Accidents
The results of the descriptive statistics reveal that situational awareness is the most contributing human factor to aircraft accidents with the Mean =112. Moreover, the Mean value of the communication breakdown is 80 which rank second as the human factors problem to aircraft incidents. Typically, communication breakdown occurs when the pilot or other aircraft crew is unable to communicate with terminals. Communication is very critical for effective operations of aircraft, a pilot will require to constantly making radio communication when on air to ensure the aircraft safety and the aircraft is on the right direction. Confusion as human factor ranks third with the Mean =70. The descriptive statistics table shows other important human factors that cause the commercial…...

214). The author notes many empirical reasons for his critique of the five-factor model. Among the many objections that are put forward is the assertion that there is in the breadth of the five factors an indefiniteness and inconsistency. Block also refers to the descriptive coarseness of the "Big Five."
Block's article has created much debate on this subject. A useful study that counters many of arguments put forward by Block is Solid Ground in the Wetlands of Personality: A eply to Block by Costa and McCrae (1995). In contrast to Block's critique, this article suggest that, "...the most impressive achievement of the FFM is its reduction of conceptual jangle, showing how constructs ostensibly as different as absorption, intuition, and need for change all reflect aspects of the single, broader construct of Openness. " (Costa and McCrae, 1995).
The validity and acceptance of the FFM model and the various aspects that…...

Personality trait and factor theories have been developed as a means of identifying common elements within the personality of different people, indeed the entire populace. Within any given group of people there are common threads of experiences, similar nurturing, and even shared genetic, yet the personality of each member is a unique construction individual elements which work together. Among those who have produced work in this area are aymond Cattell and Hans Eysenck. Each used scientific factor analysis to identify common traits or permanent dispositions of people. Cattell has identified a large number of personality traits, whereas Eysenck's research extracted only three general factors.(mcgraw-hill.com, online) Like Freud who identifies the id, ego and superego as the measurements of the personal mind, will and emotion, the categories identified by these researchers give men the ability to understand the unique functions of the person, emotions and desires.
Genome-Wide Association Study for OCD Complications
The OCD (Obsessive -- compulsive disorder) is referred as repetitive behaviors and thoughts experienced by individuals. (Visscher, Brown, McCarthy, et al. (2012). Typically, the genes' characteristics of twins and families have revealed that the OCD has the feature of multifactorial familial condition involving both environmental and polygenic factors. (Moran, 2013). Genetic studies have revealed that the interaction of the glutamatergic, serotonergic, and dopaminergic systems and genes affecting them play a crucial role in functioning of the circuit. (Yang, Lee, Goddard, Mand et al. 2011). Meanwhile, the environmental factors that include psychological trauma, adverse perinatal effects and neurological trauma may modify the risk genes, which can consequently manifest the compulsive-obsessive behaviors. (Visscher, Brown, McCarthy et al. 2012). The OCD is a frequent and, relative common debilitating neuropsychiatric disorder affecting 2% of the U.S. population. (Arnold, Sicard, Burroughs, et al. (2006). Typically, the OCD is obsessions…...
