Creating Opportunities to Developing Leadership in Private Sector Enterprises of Bangladesh-A Study in Airlines/ Shipping/Freight Forwarding Industry
Get PDFDeveloping and nurturing leadership is become very popular concept now a days. Big corporation at least understand the hidden benefit of focusing into this very important agenda for long term sustainability of business. We have experienced that organizations is automatically moving even if there is sudden demise of the owner. It happens because of the system developed through creating, retaining and nurturing leadership to create successor within the organizations. Over the years, the mind set was isolated with one man show to run everything by one individual regrettable when the owner is the signatory of all bills and vouchers to strategic decisions. This point probably gets more focus when the employee also understands and realized the necessity of growth and advancement in professions. So the perception and reality is a win-win expectation arises behind the focus to creating leadership opportunities in organizations. This article exhibits the means and opportunities to creating, developing & nurturing leadership by private sector organizations in Bangladesh giving a particular focus in airlines, shipping lines & supply chain and freight forwarding logistics companies working in Bangladesh as international joint –venture and licensing agents. This also focused on the factors related with the Leadership development, the end benefit that organizations dreamt to attain from leadership development and suggestion to take more initiatives in particular attentions. The article has been designed through structures questionnaire from about 150 employees of midlevel, senior level, and executive level including human resources managers on the employee views on current practices. The hypothesis developed in four grades related to the study objective. There is group discussion and practical work experiences of the author with one of the largest supply chain and freight forwarding logistics company operating in 21 countries around the globe. The data has been presented in an understandable way of descriptive analysis through mean, mode and standard deviation so that it might be more meaningful to contribute the relevancy of the study.

Integrated PWM solar charge controller and DCDC converter using fixed-frequency current control mode for reducing selfpower consumption of off-grid solar home system / Mohammad Shariful Islam
Get PDFThe Solar Home System (SHS) stands as a dependable and sustainable solution for powering remote areas without grid access. However, the development of SHS packages faces technical hurdles encompassing self-power consumption, advancements in PWM solar charge controllers, DC-DC converters, and integrating solar charging with voltage conversion in off-grid setups. Despite the efficiency of solar charge controllers, their affordability for smaller systems remains a concern. In addressing these challenges, this study introduces a comprehensive integration method. This method combines a single-stage boost DC-DC converter with an analog PWM solar charge controller using a fixed frequency current control mode algorithm. Through simulation studies, this approach showcases practicality and cost-effectiveness, significantly reducing the number of devices required for off-grid SHS while preserving functionalities similar to AC power systems. Key findings highlight enhanced controller features with essential safety measures, the development of an integrated controller, and a notable decrease in self-power consumption through innovative push-button switch mechanisms. The study systematically resolves technical design challenges, offering a holistic solution that enhances efficiency and cost-effectiveness in off-grid SHS. The resulting integrated system, operating in a fixed frequency current control mode, undergoes rigorous testing. It demonstrates remarkable performance with a maximum load capacity of 350 watts and exceptionally low self-power consumption of 16.89 mW. Furthermore, this integration minimizes required solar panel size without compromising essential system features, attributed to the notable decrease in self-power consumption achieved by the combined device. These achievements affirm the viability, effectiveness, and affordability of the developed controller, presenting a promising path to encourage sustainable energy consumption in underserved communities and drive progress towards a greener future
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
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
