Three factors needing to be considered for performing a cable installation are nature of material, voltage level and current carrying capacity. Also fire protection. The support system for cabling and equipment is a vital component of a properly designed data-communications system. The acceptance and use of the eia/tia-569 Commercial Building Standard for Telecommunications Pathways and Spaces by architects and engineers has proven the importance of a carefully designed and maintained cable-support system. There are six major types of cable supports: cable runway, center-rail systems, cable tray, wire basket, bridle rings or cable hooks, and wireway. Each is designed for specific purposes. One of the most important yet overlooked aspects of a network designer`s job is the specification of a cable-support system. Specifying the requirements of the design can be a difficult process. It may be helpful to consider six key areas when specifying a cable-support system:
•load capacity •grounding requirements
•materials •amount of mechanical protection required
•finishes •plenum requirements
Load capacity
The maximum cable load allowed on the system is called the load capacity. Span (the distance between supports) and load (the maximum cable weight) dictate the load capacity of a cable-support system. Different standards may use different terms when referring to load capacity but it all boils down to span and cable weight. Although load capacity can be measured in various ways, the most common methods are based on standards produced by Telcordia Technologies, the National Electrical Manufacturers` Association (NEMA), and the National Electrical Code (NEC).
The Telcordia standard was designed for cable runway, limiting a span to 5 feet in most cases, but allowing 6-foot spans in certain exceptional cases. The standard refers to cable fill as pile-up, which changes…...

Why do some students who appear to study all the time just get by, while others who don’t appear to put in as much time and effort do well? Is it all related to IQ and genetics or are some other factors involved? The truth is that success in school is not so much determined by sheer intelligence as knowing how to study. Studying is a skill. Being successful in school requires a high level of study skills. Students must first learn these skills, practice them and develop effective study habits in order to be successful. Very often the study habits and practices developed and used in high school do not work for students in college. Good study habits include many different skills: time management, self-discipline, concentration, memorization, organization, and effort. Desire to succeed is important, too. Study habits are the ways that you study- the habits that you have formed during your school years. Study habits can be good ones, or bad ones.

The "It" Factor

...Josh Brophy Personal Narrative The “It” Factor “I heard you got another A in one of your summer classes. Good job.” “Thanks. Everything is finally looking up. Mom said I’ve earned another shot up at University Park. Dad is still being stubborn, but he’ll come around eventually. I haven’t been this happy since high school.” “Seems like it. You better make the most of it.” “I will. I have to.” “If you don’t mind me asking…where were you the past year?” “Lost.” “What do you mean?” “I wish I knew.” “You know—I went to Penn State too—was there for 8 years and 3 degrees. I knew many of the most talented and brilliant people there. Professors, students, and—“ “You were one of them.” “—and you are too. You’re just as talented as any of them, including me.” “I know Mark, I agree with you.” “Then…can I ask you something?” “Is that rhetorical?” “How badly do you want to succeed?” “As badly as you did…as badly as you still do.” “Then why were you struggling so much? “Because I just wasn’t…me.” “For how long?” “—the past two years.” “So…help me understand what you’re talking about?” “You already know everything that’s happened with me...it’s all been in our conversations; little bits here—small pieces there. You’re smart enough to put it all together—and I know you already have. I’m done thinking about what’s happened in the past. I’ve already moved on.” “Fair enough.” August 22nd, 2012.

...student has an effective and good study habits, he or she can excel academically. The extent of student’s learning in academics may be determined by the grades a student earns for a period of learning has been done. It is believed that a grade is a primary indicator of such learning. If a learner earns high grades it is concluded that they may also have learned a lot while low grades indicates lesser learning. However, many experiences and studies found out that there are also several factors that would account for the grades. No single factor can be definitely pointed out as predicting grades. It has been interplay of so many factors - gender, IQ, study habits, age, year level, parent’s educational attainment, social status, number of siblings, birth order, etc. In fact, almost all of existing environmental and personal factors are a variable of academic performance. However, at this point in time, the researcher would like to investigate the possible relationship of study habits and the factors affecting it to the academic achievement of the selected 3rd Year BSMARE students in Capitol University. The investigation on this area thus becomes a real and compelling motivation for the researchers to conduct this study. Conceptual Framework Research has been conducted in order to know and determine the strategies to be done in order to attain good academic performance.

Factor Analysis

...Factor Analysis in SPSS To conduct a Factor Analysis, start from the “Analyze” menu. This procedure is intended to reduce the complexity in a set of data, so we choose “Data Reduction” from the menu. And the choice in this category is “Factor,” for factor analysis. This dataset gives children’s scores on subtests of the Wechsler Intelligence Scale for Children (WISC-III). The Wechsler scales are scored to give you a “verbal” and a “performance” IQ. The question is whether we can reproduce the verbal vs. nonverbal distinction, with the appropriate subtests grouping into each category, using factor analysis. This dialog box will appear: Factor analysis has no IVs and DVs, so everything you want to get factors for just goes into the list labeled “variables.” In this case, it’s all the variables. In some datasets, there is also a dummy “subject number” variable included. Be sure that you don’t include subject number as one of the variables for your factor analysis! To do a factor analysis, we need to select an “extraction method” and a “rotation method.” Hit the “Extraction” button to specify your extraction method. In this dialog box, you can make a number of selections. First, I want you to un-check the box labeled “Unrotated factor solution.” This is a default setting for your printout, but it just gives you information that you don’t need, and that may distract you from the real answers. So, always go into the Extraction sub-dialog and un-check......

...male rape; male rape will be referred to as a sexual violation of a man by another man through forced and non-consensual penetrative sexual intercourse. Research Questions There is a main research question, which the dissertation is based on: why are male rape victims given less attention by the police than their female counterparts? There are also sub-questions to supplement the main research question: 1) Why are police officers disregarding male rape victims? 2) Why are male rape victims reluctant to report to the police? The Rationale for Conducting the Dissertation The rationale for researching the police is because they are the first port of call for male rape victims when rape is reported, and they have a core comprehension of the factors that facilitate to the under-reporting of male rape and the impact of rape on men’s lives. The police also give information regarding male rape victims’ needs and the availability of provisions in fulfilling those needs. Therefore, the police are a good data source. The Aims of the Dissertation   To unveil the phenomenon and practice of male rape in Britain; To closely examine the male rape law, as it affects how the police respond to male rape;  To pick out and research the aspects that determine the underreporting/recording of male rape;  To identify and scrutinise male rape myths within the police subculture;  To comprehensively examine and study the police responses to male rape.

...Internal and External Factors in Big Business Jacqueline Rollerson MGT/203 October 5th, 2015 Steve Smith Internal and External Factors in Big Business There are many factors that can influence the four functions of management. Different factors can determine how you plan, organize, lead and control a company. In this paper, I will discuss how different factors such as diversity and innovation can influence a vast company like Google. Some factors are internal, like technology, and some are external, like globalization, and some can be both, like diversity. All in all Google is showing future companies how management is supposed to be done by embracing all of the different factors I will discuss below. Influencing GOOGLE In late 1998, Larry Page and Sergey Brin founded a company named Google. This American company since then has become a multinational technology company with a vast amount of products and services. They specialize in web related products and services such as online advertising, document storage, free email accounts, computing software and one of the best search engines known to man. In 2014, the company had a revenue of $66.001 billion with almost 60 thousand employees. The company has been such a success because of their expertise in management and the factors that lead their decision making processes. One external factor that keeps Google ahead is globalization. Being a private......

...THE EFFECT OF AFFECT ON FOREIGN LANGUAGE LEARNING: A REVIEW OF THE ANXIETY RESEARCH Thomas Scovel University of Pittsburgh Although studies of the relationship between affective factors and language learning proficiency abound in the literature, the evidence to support such a relationship is difficult to interpret. Much of the problem resides in the fact that a wide range of variables are lumped together under the rubric “affect.” An attempt is made to ameliorate this situation by defining affective variables in terms of traditional psychological theory and classifying them as a subset of those variables intrinsic to the learner. The conflicting evidence dealing with one important affective variable, anxiety, is then examined, and it is shown that ambiguous experimental results can be resolved if the distinction between facilitating and debilitating anxiety is drawn. Further classificatory distinctions are discussed from the abundant experimentation undertaken by applied psychologists, and an attempt is made to consider the implications of some of this research for adult language learning-for some of the new methodologies in EFL as well as for future research opportunities. Affective Variables One does not have to delve deeply into the literature on the relationship between affective variables and second language learning to discover that “affect” is a cover term under which is swept a wide range of disparate constructs and behaviors. Included under......

...Social Psychology? In the case of social psychology providing a formal definition is very complex task because of two factors: the field’s broad scope and its rapid rate of change. Social psychologists have a very broad range of interests. Yet, most social psychologists focus mainly on the following task: understanding how and why individuals behave, think, and feel as they do in social situations in the actual or imagined presence of other persons. Reflecting this fact, we define social psychology as the scientific field that seeks to understand the nature and causes of individual behaviour and thought in social situations. Social Psychology Focuses on the Behaviour of Individuals: Societies differ greatly in terms of their views concerning courtship and marriage, yet, it is still individuals who fall in love. Similarly, societies vary greatly in terms of their overall levels of violence, yet, it is still individuals who perform aggressive actions or refrain from doing so. The same argument applies to virtually all other aspects of social behaviour, from prejudice to helping. Because of this basic fact, the focus in social psychology is squarely on individuals. Social psychologists realize, of course, that we do not exist in isolation form social and cultural influences – far from it. But the field’s major interest lies in understanding the factors that shape the actions and thoughts of individual human beings in social settings. This contrasts sharply with the......

...However, when rupee depreciates it means our currency is getting weaker & its value is falling with respect to dollar. You can understand it with the following example: Suppose, currently, the exchange rate is Rs. 45 = $1, 10 months later, either of the following two cases can happen Case1: The exchange rate is say Rs. 40 = $1. This means rupee has appreciated or gotten stronger by approx 11% and you would be paying less to for a dollar Case2: The exchange rate is at Rs. 50 = $1. This means rupee has depreciated or gotten weaker by approx 11% and you end up paying more for a dollar. Factors Influencing rupee fluctuation Rupee’s appreciation or depreciation against the dollar depends on the change in demand and supply for both the currencies. If the demand for rupee is comparatively high, rupee appreciates; if low, it depreciates. The important question here is ‘what factors drive the demand for a currency?’ They are: * Interest Rate: A demand for a currency is hugely dependent on the interest rate differential between two countries. A country like India where int. rate is around 7-8% experiences greater capital inflow as investors get better return than what they might get in US. (with Interest rates of 2-3%). This results into rupee appreciation. * Inflation Rate: The demand for a country’s goods & services by the foreign buyers would be more if the inflation rate is lower in that country compared to other countries. Higher demand for goods &......

...Cotabato Academy, Inc. In Partial Fulfillment of the Requirement for the Subject English IV by Jeison L. Omandam December 01, 2011 INTRODUCTION Political history is the description and analysis of significant political occasions, movements, thoughts, and leaders. Typically it is developed around the nation states. It is distinguished from but relevant to other areas of history such as economic history, social history, and military history. Usually, political history discusses events pertaining to nation-states and the political process in particular. As per Hegelian doctrine, Political History ‘is a perception of the state with a guiding force beyond the material benefits of its subjects: it meant that the state was the root factor of historical change’.  This differs with one, for example, social history, which predominantly discusses the events and lifestyles of common folks, or people’s history, that is historical account from the view point of a lay person. A study of political history typically centers on a single nation and its political change and aggrandizement. A few historians highlight the ever increasing drift toward confined specialization in political history over the course of recent decades: ‘wherein a college professor in the 1940s resorted to identify himself as a “historian”, by the 1950s “American historian” was the designation.’ Political history is, therefore, sometimes considered as more ‘traditional’ type of history, contrasting with so......
