Influence of Securities Behaviour on Performance of Nairobi Securities Exchange Indices

This study aimed at establishing the Influence of investor’s behaviour on the performance of Nairobi Securities Exchange (NSE) indices. A reliable security market index should assist investors in making investment decisions but this is not always the case: investors at times invest in stock whose performance is not reflected in the indices. This study was guided by specific objectives which included: to establish the Influence of momentum effect, financial contagion, white noise effect, Security Price Volatility, and Herding Effect (all as independent variables) on performance of NSE indices as the dependent variable. This study was anchored to finance theories such as random walk theory, rational bubbles theory, smart money and noise trader’s theory, price formation and discovery theory, and information disclosure theories. The study was based on a period of 12 years starting from January 2004 to December 2015. The population of this study comprised of all the market participants at the NSE and thus a census approach was adopted where study period was done based on each specific objective. This research relied on primary data. Primary data was collected from all the market participants. In data analysis, a significance level of 5% was used on all objectives and a multiple regression model on each objective was used. The Statistical Package for Social Sciences (SPSS) was used on primary data for analysis. The findings for primary data showed all the indices to be insignificantly influenced by the securities behaviour but the overall NSE indices performance was statistically affected. Hypotheses were tested at 0.05 level of significance. The first hypothesis on momentum effect was not rejected on primary. The second hypothesis on financial contagion was rejected and.on the hypothesis of white noise effect, it was not rejected. The hypothesis of Security Price Volatility effect was not rejected while hypothesis of herding effect was rejected. It was concluded that all the indices play a complimentary role thus the need for the retention of all. NSE is highly contagious of the events that happen around it. The study recommends that future researchers should increase the respondents to also include investors. For the objective of momentum effect, the study recommends that more exchanges be included to get a finer detail. NSE and CMA should ensure that information availed to the researchers is obtained at minimal cost or for free to encourage more research into the security markets. Key w ords: Momentum Effect, Financial Contagion, White Noise Effect, Share Price volality effect, Herding Effect and Nairobi Securities Exchange Indices
Trade unions and precariat in Europe: Representative claims

Trade unions have been charged with neglecting labour market ‘outsiders’, while alternative actors have emerged to represent these. In response, unions have stepped up their claim to be representative of all workers, without distinction. We review the theoretical and policy debates on this issue, and argue that representation as such has been under-theorized. We draw on Saward’s concept of ‘representative claims’ to analyse the different grounds for competing assertions of representativeness. We identify four main forms of claims, and illustrate these with empirical examples. We conclude that these different claims are mutually reinforcing in stimulating attention to the outsiders, and in their interaction with institutional settings, they have a performative effect in defining new social actors.

EnglishThis study explores how and why scholars find collaborators using team formation systems. Based on theories of teams and human and social capital, we describe how scholars’ traits and social networks influence their team formation processes. We conducted a field study in Argentina in which 43 scholars used an online platform and assembled into eight interdisciplinary teams. Our results show that scholars initially tended to invite prior contacts, but, eventually, they assembled cohesive interdisciplinary teams with members they did not know before. We conclude by reflecting on how team formation platforms can enable individuals to expand their social capital.
Differential Perspectives of Cyberloafing Activities About Computer Ethics among Employee

Cyberloafing is a non-work related online activity during working hours, which is also known as a modern form of counter-productive workplace behavior. Cyberloafing is not only affecting the productivity of companies, but also opens up doors for greater threats onto companies such as malware, data security breach, slower network performances, and others. Thus, it is no longer a new topic when various reports revealed that this activity is happening in almost all organizations around the world, including Malaysia. The purpose of this study is to examine the relationship between demographic attributes of an employee of one of the agencies in Malaysia and the ethics of computer usage about cyberloafing behavior. Simple random sampling was assigned to several 95 respondents from the agency. The accumulated data were then analyzed; descriptive statistics were used to interpret and evaluate the research outcomes. The findings of this study indicate that male gender, younger age employees, and employee of higher-level positions are more involved in cyberloafing than other group respondents. Yet, there is no significant relationship between the level of education and cyberloafing, as well as ethics and cyberloafing behavior. Hence, it's highly advisable to request from organizational leaders to introduce appropriate policies that help to manage employees' behavior toward cyberloafing.
Writing Portfolios at the Elementary Level: A Study of Methods for Writing Assessment.

The hyperbolic expectations associated with performance assessment have created a situation paradoxically analogous to previous testing practices now in the throes of mass repudiation. Commercial test producers, you may recall, consistently reminded users that the purposes of their traditional (i.e., multiplechoice) measures were limited. It was the presumably school users who expanded the applications of these achievement tests from reports of individual achievement to measures of accountability. When high stakes became associated with performance, so the story goes, then instruction inappropriately focused on the test. Validity of interpretation suffered, some believe standards were lowered, and in any event, these tests became regarded by many as an educational scourge.
To Share or Not to Share

Audiences play a fundamental role in disseminating and evaluating news content, and one of the big questions facing news organizations is what elements make content viral in the digital environment. This comparative study of the United States, Brazil and Argentina explores what values and topics present in news shared online predict audience interaction on social media. Findings shed light on what news values and topics trigger more audience responses on Facebook and Twitter. At the same time, a comparison between popular content produced by traditional media versus online-native media reveals that the former lean more toward government-related news and conflict/controversy news values than online native media. Brazilian stories prompted more social media interactivity than content from the United States or Argentina. Through content analysis, this study contributes to improving our understanding of audiences’ news values preferences on social networks. It also helps us to recognize the role of users’ online activities (sharing, commenting and liking) in the social construction of news and meaning inside the networked sphere. Finally, it opens an old media debate about whether providing and sharing too much media content with conflict, controversy and oddity could potentially hinder understanding and agreement in society. Articles were collected via media tracking and the data collection company NewsWhip.
Short-term share price overreaction : evidence from the Johannesburg Stock Exchange

The Overreaction Hypothesis and share price overreaction has been a widely researched phenomenon since the 1980s, although most work has focused on longer-term share return reversals. As an emerging market and part of the BRICS collective, South Africa provides an interesting investment environment within which to investigate this phenomenon. Limited research has been done in South Africa on share price overreaction, again nearly all focusing on the longer term. This dissertation examined short term overreaction (over 1 and 5-day periods) on the Johannesburg Stock Exchange (JSE) over the period July 2000 to June 2015. Furthermore, periods of financial crisis were isolated from the full sample period and tested separately, in order to assess whether periods of financial instability affect the magnitude of share price overreaction on the JSE. Whereas the common approach in this field is to investigate overreaction on a relative basis (for example by ranking share returns over a prior period and focusing on extreme relative performances), this thesis follows other literature that examines share return reversals following extreme one-day share price changes beyond absolute cut-off values (in this case ±5% and ±10%). The methodology considered an abnormal returns measure based on total return index values, and used a multivariate regression to test for one day and five day share return reversals. The effect of average prior returns, market volatility, company size, value, price-toearnings and book-to-market ratios on abnormal returns were also considered. Lastly, a portfolio strategy based on one day and five day return reversals following large positive or negative one-day returns was investigated to test for usability as a possible trading strategy. Significant evidence was collected in support of short-term reversals. The results remained valid after robustness checks, and consistent coefficients were obtained for all variables, except the book-to-market ratio. A notable portion of the observed abnormal returns were unexplained by the conventional effects of company size and value. There was no statistically significant effect due to the Global Financial Crisis, in spite of a higher frequency of large price shifts during this period. A trading strategy employing these insights did not provide statistically significant riskadjusted excess returns relative to the All Share Index when traded frequently, thus supporting the view that the JSE is at least weak-form efficient given transaction costs. This study contributes to the market efficiency literature on the JSE, but also for the first time investigates very short term share return reversals and overreaction within the South African context using an absolute extreme share return approach, as opposed to a relative share performance approach.

The Neural Architecture of General Knowledge

Cognitive performance varies widely between individuals and is highly influenced by structural and functional properties of the brain. In the past, neuroscientific research was principally concerned with fluid intelligence, while neglecting its equally important counterpart crystallized intelligence. Crystallized intelligence is defined as the depth and breadth of knowledge and skills that are valued by one's culture. The accumulation of crystallized intelligence is guided by information storage capacities and is likely to be reflected in an individual's level of general knowledge. In spite of the significant role general knowledge plays for everyday life, its neural foundation largely remains unknown. In a large sample of 324 healthy individuals, we used standard magnetic resonance imaging along with functional magnetic resonance imaging and diffusion tensor imaging to examine different estimates of brain volume and brain network connectivity and assessed their predictive power with regard to both general knowledge and fluid intelligence. Our results demonstrate that an individual's level of general knowledge is associated with structural brain network connectivity beyond any confounding effects exerted by age or sex. Moreover, we found fluid intelligence to be best predicted by cortex volume in male subjects and functional network connectivity in female subjects. Combined, these findings potentially indicate different neural architectures for information storage and information processing. © 2019 European Association of Personality Psychology
Promoting EFL students’ accuracy and fluency through interactive practice activities

This study examined the effectiveness of interactive activities at facilitating EFL students’ production of English relative clauses. Thirty-seven EFL learners in Chile carried out interactive activities designed to elicit relative clauses. Pre- and posttests were used to examine whether carrying out the activities facilitated the students’ production of relative clauses. All interactions were audio-recorded and the transcripts were analyzed to determine how accurately and fluently the students produced relative clauses before, during, and after the practice activities. Whereas accuracy was defined as errors involving relative clause formation, fluency was operationalized in terms of the number of pauses, false starts, and self-corrections that occurred within relative clauses. The results showed that the students produced significantly more accurate relative clauses on the posttest; however, their production of dysfluencies remained unchanged. Implications for the use of interactive activities are discussed.
Fenomena Gizi Buruk pada Keluarga dengan Status Ekonomi Baik: sebuah Studi Tentang Negative Deviance di Indonesia

Negative defaviance is a term as the oposite condition of positive deviance that has been used to described the performance regarding health, growth and development of certain children in the community and family. From the perspective of young child nutrition, negative deviants are children who grow and develop insufficiency in good or high income families. This condition was cased by poor child care practice due to low educated mother or low exposure of health and nutrition education, and may caused by tradition and beliefs relating to food preparation, anda also feeding techniques. This paper will discuss some aspects of negative deviance such as the definition of negative defiance, epidemilogical aspect and also prevention aspects.Key words: negative defiance, undernutrition, under five years children
Analysis Of The Open Selection Process For Structural Officials (Echelon II) In Sleman Regency

The administration of government is certainly very influenced by bureaucracy which is an instrument or an organization that helps in realizing or implementing a policy that has been previously set. The open selection is the process of filling in a position by opening a selection to all those who have the competency or ability determined to fill a certain position. This study is aims to analyze the open selection for echelon II Officials both in Yogyakarta Province which is Sleman Regency. The method that used in this study is a qualitative approach which did the depth interview with several stakeholders that involved. The result of this study are the selection mechanism conducted in Sleman Regency in 2017 lasts 2 times and all of them have referred to the applicable regulations and most importantly have implemented a merit system. In the selection implementation the position was carried out by a selection committee formed based on recommendations from KASN (Commission Of The State Civil Apparatus). The involvement of political officials in this case the regent in the open selection process only exists after the selection committee has issued 3 names that have passed. However, the involvement of political officials is positive because it considers the results of the selection. This is also because the Regent will cooperate with one of the 3 names to realize the vision and mission that has been set. Keyword: Open selection, Echelon II, Promotion.
Improving Topic Models using Conceptual Data

Laboratoire ERIC, Universit e Lyon 2 , 5 Avenue P. Mendes, Bron, 69676, France {marian-andrei.rizoiu, julien.velcin}@univ-lyon2.fr Abstract. We propose a system which employs conceptual knowl edge to improve topic models by removing unrelated words fr om the simplified topic description. We use WordNet to detect which topical words are not conceptually similar to the others and then test ou r assumptions against human judgment. Results obtained on two different corpora in different test conditions show that the words detected as unrelated had a muc h greater probability than the others to be chosen by human evaluators as not being part of the topic at all. We prove that there is a strong correlation between the said probability and an automatically calculated topical fitness and we dis cuss the variation of the correlation depending on the method and data used.

The Assessment of Phase of Preschool Language: Applying the language benchmarks framework to characterize language profiles and change in four- to five-year-olds with autism spectrum disorder

Background and aims We introduce the Assessment of Phase of Preschool Language (APPL), a rating form that characterizes children’s language according to a well-established framework recommended by Tager-Flusberg et al. (2009). The language benchmarks framework defines children’s language as falling at one of the Pre-verbal, First Words, Word Combinations, Sentences, or Complex Language phases for phonology, vocabulary, grammar, pragmatics, and overall language. The APPL is a flexible assessment tool that allows assessors to determine language phase using a range of assessment sources: natural language samples, standardized measures, and/or parent rating forms. Using the APPL, we examined language profiles in four- and five-year-olds with autism spectrum disorder and explored language development during a community-based Naturalistic Developmental Behavioral Intervention program. Methods Community speech-language pathologists completed the APPL with 95 four- and five-year-olds at the beginning of the treatment. The APPL was re-administered after a mean of 10 months of intervention (SD = 2 months) for 46 of these children. Children received treatment for up to 15 h per week in their homes and/or community childcare centers. Pivotal Response Treatment was the main form of intervention. The Picture Exchange Communication System or other augmentative and alternative communication systems were also used with many pre-verbal children. Results At the beginning of intervention, the most common language phase was Word Combinations (44%), followed by Pre-verbal (26%), Sentences (20%), and then First Words (10%). Only 24% of children had even profiles (i.e. phonology, vocabulary, grammar, and pragmatics skills at the same level). Phonology was a common area of relative strength, and pragmatics was a common area of relative weakness. Ten months of intervention was associated with gains in overall language phase for 37% of children. Approximately half gained at least one phase in Grammar (57%), Vocabulary (51%), and Phonology (46%), while Pragmatics improved for 33%. Gains varied based on initial language phase. Inclusion of skills using augmentative and alternative communication enhanced interpretation of change during intervention. Conclusions Four- and five-year-olds with autism spectrum disorder in this sample tended to have uneven skills across expressive language domains. Community-based Naturalistic Developmental Behavioral Intervention was associated with gains in language phase in older preschoolers with autism spectrum disorder. Gains varied across language domains and were influenced by initial language phase. Implications The Assessment of Phase of Preschool Language is a useful tool to support consistent application of the language benchmarks framework. It is important to consider all language domains when characterizing language skills and treatment impact in children with autism spectrum disorder.
A Content Analysis of Appeals in Food and Beverage TV Commercials

This study was conducted to analyze the appeals of food and beverage TV commercials which were broadcasted on Turkey’s national and international TV channels between 2011-2018. The main aim of this research was to do a reality check and try to compare different groups of food TV commercials according to their basic characteristics and appeal strategies. The research followed Aristotle’s modes of persuasion, and product appeals are identified primarily from the literature review and summarized into a systematic coding. Data gathered from the broadcasted TV commercials are reached through the companies own YouTube channels. A total sample of 400 national and international food and beverage TV commercials are grouped and analyzed according to their characteristics such as dairy, beverages, foods for breakfast, oil, meat, pulse and legumes, sauces and dressings, chocolate, and confectionary. The results of the study illustrate the range of techniques used to advertise foods to consumers and the techniques do not generally differ according to the type of food advertised. The most typical product appeals were mood alteration and taste both in national and international TV commercials.
