Relationship between Time Management and Academic Performance among Orphaned Secondary School Students of Kenya

The study investigated the relationship between time management and academic performance among orphaned secondary school students of Kenya. This study adopted an ex post facto research design with which a saturation sampling technique was employed. The study population constituted 300 secondary school going orphans and 23 principals. The sample of the study comprised 300 secondary school going orphans and 7 principals picked out through saturated and simple random sampling respectively. The research instruments that were used were students' questionnaires, document analysis and interview guide for the head teachers. The validity of the research instrument was ensured through expert judgments by University lecturers in the department of psychology. To test the reliability of the instruments, the researcher employed the test retest and correlation coefficient of 0.891 was reported. The Pearson Product Moment correlation coefficient (r .906) computed indicated that there was high positive correlation between time management and academic achievement among orphaned secondary school students. Ministry of Education in general should understand the plight of orphans and provide them with improved services like trained counselors who would be able to provide orphaned children with appropriate counseling services.
Do Liquidity and Financial Leverage Constrain the Impact of Firm Size and Dividend Payouts on Share Price in Emerging Economy

This study investigates the influence of liquidity position and financial leverage on the relationship of share price with firm size and dividend payouts in Pakistan by using the annual panel data of 356 non financial firms listed on Karachi stock exchange from the period of 1999 to 2013. Pedroni panel cointegration approach confirms the valid long run relationship between considered variables. Results indicate that firm size and dividend payout have significant positive relationship with the firms' stock prices in long run. Results of causality test show the bidirectional causal relationship of firm size and dividend payout with stock prices in non financial firms of Pakistan. The findings also support the dividend relevance theory, which means dividend payout have significantly impact on stock price, stock returns and firms' value. It is suggested that investors should invest in stock of those firms who pay higher dividend and having large firm size in order to get higher returns on their investments. On the other hand, results also suggest that the coefficient of dividend payout is more than coefficient of firm size. In the light of these findings management of firms should focus more on dividend payout than retained earnings to increase the firms' value in the market.
The Impact of Board Gender Composition on Dividend Payouts

This paper investigates whether female independent directors are more likely to impose high dividend payouts. We find evidence that firms with a larger fraction of female directors on their board have greater dividend payouts. This finding is robust to alternative econometric specifications, and alternative measures of dividend payouts. The positive effect of gender composition on dividends remains when we employ propensity score matching and the instrumental variable approach to address potential endogeneity concerns. Furthermore, we find that board gender composition significantly increases dividends only for firms with weak governance, suggesting that female directors use dividend payouts as a governance device.
The effect of ownership structure on dividend policy: evidence from Turkey

This paper aims to investigate the impact of ownership structure on dividend policy of listed firms in Turkey. Particularly, it attempts to uncover the effects of family involvement (through ownership and board representation) non family blockholders (foreign investors, domestic financial institutions and the state) and minority shareholders on dividend decisions in the post 2003 period as it witnesses the major economic and structural reforms.  The paper uses alternative dividend policy measures (the probability of paying dividends, dividend payout ratio and dividend yield) and uses appropriate regression techniques (logit and tobit models) to test the research hypotheses, by focusing on a recent large panel dataset of 264 Istanbul Stock Exchange listed firms (non financial and non utility) over a 10 year period 2003 2012.  The empirical results show that foreign and state ownership are associated with a less likelihood of paying dividends, while other ownership variables (family involvement, domestic financial institutions and minority shareholders) are insignificant in affecting the probability of paying dividends. However, all the ownership variables have a significantly negative impact on dividend payout ratio and dividend yield. Hence, the paper presents consistent evidence that increasing ownership of foreign investors and the state in general reduces the need for paying dividends in the Turkish market.  Because of the absence of empirical research on how ownership structure may affect dividend policy and the data unavailability for earlier periods in Turkey, the paper cannot make comparison between the pre and post 2003 periods. Nevertheless, this paper can be a valuable benchmark for further research.  The paper reveals that cash dividends are not used as a monitoring mechanism by investors in Turkey and the expropriation argument through dividends for Turkish families is relatively weak. Accordingly, the findings of this paper may benefit policymakers, investors and fellow researchers, who seek useful guidance from relevant literature.  To the best of the authors' knowledge, this paper is the first to examine the link between ownership structure and dividend policy in Turkey after the implementation of major reforms in 2003.
Challenges in Automotive Fuel Cells Recycling

Fuel cell driven cars belong to the 'zero emission' vehicles and should contribute to lower CO2 emissions. However, they contain platinum, which is known as a critical material in the European Union. This study investigated the potential contribution of recycling fuel cell vehicles (FCV) to satisfy the platinum demand arising from a widespread deployment of fuel cell vehicles in Europe. Based on a qualitative examination of the four consecutive steps in the recycling chain (collection, dismantling, disassembly and pre processing, material recovery) of fuel cell vehicles, two recycling scenarios were developed. Using dynamic material flow analysis, these two recycling scenarios were applied to two scenarios for the market penetration of fuel cell vehicles in nine European lead markets to deliver both the associated impact on platinum demand and the contribution of recycling for meeting this demand. The diffusion of FCV in Europe will not cause a depletion of platinum resources in the short term, as the calculated 537.06 t and 459.24 t in cumulative platinum requirements are far below the currently estimated global reserves. However, concerns regarding the future development of platinum supply and demand remain.
Techno Economic Modeling and Analysis of Redox Flow Battery Systems

A techno economic model was developed to investigate the influence of components on the system costs of redox flow batteries. Sensitivity analyses were carried out based on an example of a 10 kW/120 kWh vanadium redox flow battery system, and the costs of the individual components were analyzed. Particular consideration was given to the influence of the material costs and resistances of bipolar plates and energy storage media as well as voltages and electric currents. Based on the developed model, it was possible to formulate statements about the targeted optimization of a developed non commercial vanadium redox flow battery system and general aspects for future developments of redox flow batteries.
Adaptive behaviors in multi agent source localization using passive sensing
Venue: Adapt. Behav.

In this paper, the role of adaptive group cohesion in a cooperative multi agent source localization problem is investigated. A distributed source localization algorithm is presented for a homogeneous team of simple agents. An agent uses a single sensor to sense the gradient and two sensors to sense its neighbors. The algorithm is a set of individualistic and social behaviors where the individualistic behavior is as simple as an agent keeping its previous heading and is not self sufficient in localizing the source. Source localization is achieved as an emergent property through agent's adaptive interactions with the neighbors and the environment. Given a single agent is incapable of localizing the source, maintaining team connectivity at all times is crucial. Two simple temporal sampling behaviors, intensity based adaptation and connectivity based adaptation, ensure an efficient localization strategy with minimal agent breakaways. The agent behaviors are simultaneously optimized using a two phase evolutionary optimization process. The optimized behaviors are estimated with analytical models and the resulting collective behavior is validated against the agent's sensor and actuator noise, strong multi path interference due to environment variability, initialization distance sensitivity and loss of source signal.
Predicting Student Dropout in Higher Education
Venue: ArXiv

Each year, roughly 30% of first year students at US baccalaureate institutions do not return for their second year and over $9 billion is spent educating these students. Yet, little quantitative research has analyzed the causes and possible remedies for student attrition. Here, we describe initial efforts to model student dropout using the largest known dataset on higher education attrition, which tracks over 32,500 students' demographics and transcript records at one of the nation's largest public universities. Our results highlight several early indicators of student attrition and show that dropout can be accurately predicted even when predictions are based on a single term of academic transcript data. These results highlight the potential for machine learning to have an impact on student retention and success while pointing to several promising directions for future work.
Deciphering the Meanings and Explaining the South African Higher Education Student Protests of 2015 16

2015 16 witnessed the re entry in very visible ways of South African university students onto the higher education terrain. This is not to say that students have not been part of steering and shaping higher education through institutional governance mechanisms, or that there have not been student protests post 1994, especially at the historically black universities and at institutions that were merged as part of the restructuring of the higher education landscape after 2000. However, it is suggested that there was something especially dramatic and distinctive about the 2015 16 protests. So wherein lay the drama and distinctiveness of the protests? Did they have to do with the breadth and depth of mobilization, the targets of opposition, and the nature of the demands? Or in serving as a salutary reminder of the tardy pace and limited degree of transformation in higher education and, given the connections between higher education and society, of unfinished business in the wider economic, political, and social domains? How are the 2015 16 protests to be theorized and explained, and their character and significance for universities, higher education, and the wider polity and society to be understood? Could the 2015 16 protests be one manifestation of the "organic crisis" of South African higher education, which necessitates major "formative action" on the part of the state and other key actors?

Does higher education service quality effect student satisfaction, image and loyalty? A study of international students in Malaysian public universities

The purpose of this study is to investigate the effect of Malaysian public universities' service quality on international student satisfaction, institutional image and loyalty.  A total number of 400 questionnaires were distributed to international students, selected using convenience sampling technique, at three public Malaysian university campuses in Kuala Lumpur. Of this, 241 were deemed fit for analysis (60 per cent response rate) Partial Least Squares Structural Equation Modeling was used to analyze the collected data, assess the model and test hypotheses.  The findings show that all the five dimensions of higher education service quality influence student satisfaction which in turn influences institutional image, and together, they influence student loyalty.  There are a number of limitations associated with this study. First, the findings of the study are based on data from international students at only three Mala.
Technology enhanced teaching and learning in South African higher education A rearview of a 20 year journey
Venue: Br. J. Educ. Technol.

In the last 20 years, the South African higher education has changed significantly, influenced by global trends national development goals and pressure from local educational imperatives, in the context of a digitally networked world. Shifts in technology enhanced pedagogical practices and in discourses around information and communication technologies (ICTs) have had varying degrees of influence in higher education. This paper takes a rearview of a 20 year journey of technology enhanced learning in South African higher education. An analysis of literature view is presented chronologically in four phases: phase 1 (1996 2000) phase 2 (2001 05) phase 3 (2006 10) and phase 4 (2011 16) In phase 1 technology was used predominantly for drill and practice, computer aided instruction, with growing consciousness of the digital divide. In phase 2 institutions primarily focused on building ICT infrastructure, democratizing information, policy development and research; they sought to compare the effectiveness of teaching with or without technology. During phase 3 institutions began to include ICTs in their strategic directions, digital divide debates focused on epistemological access, and they also began to conduct research with a pedagogical agenda. In phase 4 mobile learning and social media came to the fore. The research agenda shifted from whether students would use technology to how to exploit what students already use to transform teaching and learning practices. The paper concludes that South Africa's higher education institutions have moved from being solely responsible for both their own relatively poor ICT infrastructure and education provision to cloud based ICT infrastructure with 'unlimited' educational resources that are freely, openly and easily available within and beyond the institution. Although mobile and social media are more evident now than ever before, teaching and learning practice in South African higher education remains largely unchanged.
Hearing profile and postural sensory integration deficits in Parkinson's disease

The objectives of this study were to evaluate auditory function and postural instability in Parkinson's disease (PD) patients, and to correlate audiological findings and postural instability with the severity and duration of PD.  The severity of motor symptoms and staging were ascertained with the Unified Parkinson's Disease Rating Scale and the Hoehn and Yahr Scale, with identification of the side most affected by PD and the disease duration. Audiologic evaluation consisted of history taking, otoscopic examination, pure tone audiometry, acoustic immittance measures, speech audiometry, and brainstem auditory evoked potentials. Sensory Organization Test was also conducted. Of 55 PD patients, 31 were enrolled in this study, along with 31 healthy age matched and sex matched controls.  Our PD patients showed high frequency, age dependent unilateral or bilateral hearing loss, significant increase in wave V peak latency and I V and III V interpeak latencies, and significant decrease in composite score, vestibular score, and visual score and significant increase in preferential visual score in comparison with controls. All these findings were significantly correlated to disease severity and duration.
Transforming the study of plants and people: A reflection on 35 years of The New York Botanical Garden Institute of Economic Botany
Venue: Brittonia

The creation of the NYBG Institute of Economic Botany (IEB) was intended to help revitalize the field of economic botany and ethnobotany, through the work of a multidisciplinary staff who would study important issues of great human concern. Early staff appointments included anthropologists and ecologists, who utilized perspectives from the social and natural sciences that, when combined with NYBG staff trained in systematic botany, economic botany and ethnobotany, have been effective in changing research approaches to the study of the relationships between plants, people and culture. IEB staff activities include research projects, teaching in graduate and undergraduate programs, mentoring students, publishing the results of scientific research and outreach to the public as well as communities in areas where its programs operate. Thirty five years after the creation of the IEB, the fields of economic botany and ethnobotany have greater preeminence as scientific disciplines and classes in these topics have grown from only a handful at universities in the 1980s to over 70 today. Several dozen graduates of the IEB's Ph.D. programs now teach or carry out research at many major institutions around the world, as well as in the private sector; it is this next generation who will continue and expand studies of this field.
From learning to game mechanics: The design and the analysis of a serious game for computer literacy
Venue: 2016 11th Iberian Conference on Information Systems and Technologies (CISTI)

This paper presents the design, development and analysis of a game for computer literacy. Specifically, the game addresses educational objectives included in the curriculum of non technological careers, such as the identification and analysis of concepts related to basic hardware components of a computer. These objectives are joined with those of a video game, i.e. live an attractive, motivating and enriching experience. The game has focused on the interaction between the player, who plays the role of a student, a 3D virtual computer, and a character who plays the role of the teacher. The player interacts with the computer and answers a series of inquiries posed by the teacher, all related to components of the 3D computer located in the game scenario, which represents the teacher's office. For each correct answer, the player receives a sounded feedback and messages of encouragement from the teacher, as well as points. Once the player completes each level, the result is stored and can be displayed in a scoreboard. Game analysis has been done using the so named LM GM framework, which is an analytical model proposed by GaLA (Game and Learning Alliance, the European Network of Excellence on Serious Games) that maps learning mechanics (LM) to game mechanics (GM) The results of the analysis indicate that the serious game seemly integrates learning objectives as well as LM and GM.
An Older Age Advantage? Emotion Regulation and Emotional Experience After a Day of Work

The goal of this study was to investigate age differences in emotional experience after a day of work, and the role of emotion regulation strategy use in shaping emotional experience. Based on the lifespan literature, we predicted that older workers enjoy higher emotional well being, in particular in terms of higher levels of low arousal positive emotions and lower levels of high arousal negative emotions, than young workers. We further predicted that age differences in emotional experience are mediated by a more adaptive profile of habitual emotion regulation strategy use in older compared to young workers. Multilevel mediation analysis of 832 daily surveys completed by 92 healthcare professionals failed to provide evidence of age differences in after work emotions. Yet, age was indirectly associated with emotional experience via enhanced use of adaptive strategies (e.g. positive reappraisal, savoring) and lower use of maladaptive strategies (e.g. rumination, fault finding) Overall, findings support an older age advantage in emotion regulation, which in turn, benefits emotional well being in the evening, a time of day that is essential for recovery from work demands.
How safe is nuclear power? A statistical study suggests less than expected

After the Fukushima disaster, the authors analyzed all past core melt accidents and estimated a failure rate of 1 per 3704 reactor years. This rate indicates that more than one such accident could occur somewhere in the world within the next decade. The authors also analyzed the role that learning from past accidents can play over time. This analysis showed few or no learning effects occurring, depending on the database used. Because the International Atomic Energy Agency (IAEA) has no publicly available list of nuclear accidents, the authors used data compiled by the Guardian newspaper and the energy researcher Benjamin Sovacool. The results suggest that there are likely to be more severe nuclear accidents than have been expected and support Charles Perrow's "normal accidents" theory that nuclear power reactors cannot be operated without major accidents. However, a more detailed analysis of nuclear accident probabilities needs more transparency from the IAEA. Public support for nuclear power cannot currently be based on full knowledge simply because important information is not available.
