Effects of Perceived Psychological Contract Breach on Organizational Commitment of Public Universities Academic Staff in Tanzania
Get PDFThe study sought to determine the effects of perceived psychological contract breach on organizational commitment of public universities’ academic staff in Tanzania. The specific objectives were; to determine whether perceived psychological contract breach affect organizational commitment, whether perceived psychological contract breach affect affective organisational commitment, whether perceived psychological contract breach affect continuance organizational commitment, whether perceived psychological contract breach affect normative organisational commitment and whether after controlling the effects of demographic factors such as age, education, gender, tenure and academic rank perceived psychological contract breach still affect the university’s academic staff’s organisational commitment. A cross-sectional survey was carried out on a sample of 187 academic staff from Tanzania public universities. Descriptive statistics, correlation, linear and multiple linear regression analysis techniques were applied. The study found that perceived psychological contract breach significantly negatively affected organizational commitment and its dimensions namely affective, continuance and normative. For the demographics, regression results shows revealed that psychological contract breach significantly and negatively had the power to affect organizational commitment with a combination of age, marital status and tenure. It is recommended that universities management should make sure that all promises to newly recruited academic staff are fulfilled. In addition, strategies to motivate married couples and their families may help to make academic staff more committed. Young academic staff should be motivated by further training, being engaged in research and consultancy while the older ones should be guaranteed their tenure and good pay
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Mobile Phones Usage in Improving Access to Cotton Seeds: A Case of Sengerema District, Mwanza Region
No full textTechnological change and adoptability is a fundamental phenomenon from one stage to another. Usually the change to be a change should be demarcated and differentiated from the previous situation as compared to the present situation. The study has identified the value of prompt dissemination of cotton farming practices information in recent years with the aid of mobile phones as a tool for sophisticating farming processes. The major focus was on the application of mobile phones in communication and payment modalities of information between cotton farming stakeholders to speed up the process. The conclusion of the study was based on the data gathered through questionnaires from four hundred (400) cotton farmers in Sengerema District. It was observed that, despite of many people having mobile phones of different nature, they mostly use them to share common information and contributes very minimal on farming practices. Therefore, this study has identified such weaknesses and suggested best practices of using mobile phones among cotton stakeholders in both information dissemination and payment systems. In short, the use of mobile phones in cotton farming practices helped vigorously in spreading information and payments related to agriculture, eventually resulted into good quality and quantity of cotton output. Key Words: Mobile phones, Technology, Cotton farming, Informatio
Relationship between Psychological Contract Breach and Affective Commitment among Public University Academicians in Tanzania: The Mediating Role of Job Satisfaction
Get PDFThis study examined the effect of two job attitudes – perceived psychological contract breach and job satisfaction on affective commitment as well as whether job satisfaction mediates the relationship between psychological contract breach and affective commitment. A cross-sectional explanatory research design was used involving a sample of 223 academicians drawn from five public universities in Tanzania. Multiple regression analysis techniques were used to examine the effect of psychological contract breach and job satisfaction on academicians’ affective commitment to their respective universities. The mediation role of job satisfaction was tested using Andrew Hayes’ Process Macro 4.0. The results show that the two predictors explained about 62 percent of the variance in affective commitment where psychological contract breach and jobs satisfaction have, respectively, statistically significant negative and positive effects. Job satisfaction, in addition to being the most influential predictor, mediates significantly, but partially, the relationship between psychological contract breach and affective commitment. The study concludes that while psychological contract breach negatively affects the academicians’ affective commitment, part of this effect is indirect through job satisfaction. It, therefore, recommends that honoring psychological contracts is important for cultivating affection and identification of academicians with their universities, and that these outcomes would be enhanced if job satisfaction-enhancing measures are also stepped up
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
