Infectious Disease Mortality Prediction

When mortality statistics are reported for infectious diseases, they commonly reflect the ratio for the entire population impacted from it. This causes an underestimation since the frail members of the population are impacted at a higher rate. With the remaining healthy members, the mortality rate becomes skewed. With this project, we study predicting mortality under varying frailty conditions to account for the hidden heterogeneity\u27s impact on the parameter estimates.https://ir.library.illinoisstate.edu/ursmat/1000/thumbnail.jp

“Apparel Merchandising” –the Unsurpassed Instance of Contemporary Business Communication

This intangible manuscript aspires to present a research archetype for International Business Communication into Apparel Merchandising, research with special reference to the scenario of Bangladesh Apparel Industries. To widen a prototype, international business communication first is defined, and the opportunities of Bangladesh Apparel Industries as well as Merchandising face in international business are described, as are the methods used to deal with obstacles and foster better global management and intercultural communication. The key issue of emergent Communication Model is emphasized. To systematize international business communication research with reference to Bangladesh Apparel Merchandising, a research schema is accessible involving study of: correct custom of English, the connotations of international business communication terms, and the relationship of English as an international business language to its diverse users. The conducting theories in this research will come from Modern and International aspects. Proper Communication will be the mediator of globalization, and Bangladesh apparel Merchandising must accept this authenticity and covenant with it. So far, they have not yet developed a satisfactory way of doing so. However, appropriate methodologies are available, as presented in the manuscript. Bangladesh apparel Industries have delayed behind European and US companies in coping with the communication problems encouraged by the globalization. This manuscript sets out a methodology for developing the research needed to acquire practical steps to solve the problem. The manuscript offers a model of ways to standardize international business communication research so that Apparel Merchandising can develop ways of coping with the communication problems of globalization.

Corporate Mandatory and Voluntary Disclosure Practices in Bangladesh: Evidence from listed companies of Dhaka Stock Exchange

This paper investigates the extent and level of mandatory and voluntary disclosure practice of companies in Bangladesh. The paper has been conducted on the sample of 54 listed companies in Bangladesh for a data period of 2010 to 2013. This paper also reports the results of the association between company specific characteristics and mandatory as well as voluntary disclosure of the sample companies. Findings indicate on an average 71% of the companies analyzed disclose above-average number of additional information. The explanatory analyses has shown that firm size in terms of total asset and status of the company significantly and positively affect the level and extent of voluntary disclosure in the annual report of Bangladeshi companies. In case of mandatory disclosure level results point out that companies in general have not reacted adequately to the mandatory disclosure requirements of the regulatory bodies. The study reveals that disclosure compliance is poor among listed companies. They disclosed an average of 50.62% of the items selected during the study period of 2010 to 2013. The minimum score found in the study is 20.89% and the maximum is 77.08%. Using panel data regression analysis this study has found that company age and the status of the company (industry type) have appeared to be significant factors for mandatory disclosure. On the other hand company size in terms of total asset and sales, and company profitability was also found to have no effect on mandatory disclosure. Keywords: Mandatory disclosure, Voluntary disclosure, Disclosure index, Bangladeshi companies, Corporate Governance

Online Shopping Behavior of Bangladeshi People

Bangladesh as a developing country has been seeing a lot of dependence in digital money transaction with which people’s habit of Online shopping is increasing furthermore. To understand people’s shopping behavior more concretely we went ahead and did a research on it. The main incentive of the research is to find out the shopping behavior of the people in Bangladesh and the kind problem that people are generally facing that is working as a discouraging factor. For this reason, a structured and closed ended questionnaire was used on a random sample population to know the behavior of the people regarding online shopping. From the answers of those questions, it is found that, the 18-23 years old people do the online shopping most. Moreover, male persons are more likely to do shopping on online than the female group. For shopping, most of the people use “Facebook Pages” according to our research. Here, many people are also unaware of the apps that the online shopping service provider provides. Not only that, most purchased items on online is clothing and after that most purchased item is food. While purchasing foods from the online, most people choose “Food Panda”. Our survey also found that for buying electronic gadgets most people use daraz.com and evaly.com. Much to our surprise, a lot of people doing online shopping on a regular basis feel quite secured on the platform. However, most people think that online services need to be improved and we saw a lot of complains about the displayed or descripted product not matching the actual product. Moreover, they are also unhappy with delivery service that online service providers provide to the customer. The most alarming part that we found out through our survey is many people are taking online shopping service but the frequency is too low, which is once in a month. Another major complain about online shop is delivery issues. Most of the cases it seems that delay in delivery for products create lot of problem for customers. Keeping all those behaviors and dissatisfactions of the consumer in our mind, we have tried to recommend some strategy to the online service provider to remove those dissatisfactions among the people. If these issues and problems like these can be resolved, more people might accept the process of Online Shopping and a lot of people might consider doing Online Shopping more frequently. The main objective of this research paper is to understand how people in Bangladesh view the whole platform of Online Shopping, it’s perks and problems and how it can be improved more to attract more in order to attract more people toward the platform.

UNDERSTANDING COMMUNICATION NETWORK COHESIVENESS DURING ORGANIZATIONAL CRISIS: EFFECTS OF CLIQUE AND TRANSITIVITY

Various terms such as organizational mortality, organizational death, bankruptcy, decline, retrenchment and failure have been used in the literature to characterize different forms and facets of organizational crisis. Communication network studies have typically focused on nodes (individuals or organizations), relationships between those nodes, and subsequent affects of these relationships upon the network as a whole. Email networks in contemporary organizations are fairly representative of the underlying communications networks. We show that changes in communication networks and its associated group cohesiveness have implications for studying organizational crisis. In this paper, we analyze the changing communication network structure at Enron Corporation during the period of its crisis (2000-2001). Our goal was to understand how communication patterns and structure were affected by organizational crisis. Drawing on communication network crisis and group cohesiveness theory, we tested several propositions using the Enron email corpus: (1) Number of cliques increases, and (2) Communication network becomes increasingly transitive as organizations experience crisis. The results of the tests and their implications are discussed in this paper

Towards A Scale Free Network Approach to Study Organizational Communication Network

In this experiment, we study the scale free network property of an organizational communication network. We used social network analysis methods during organizational crisis period that captures the dynamics of communication networks. We did not find any significant fluctuation between the actor prominence in daily and aggregated networks. We found that email communication network displays a high degree of scale free behavior described by power law

Optimal Planning of Standalone Solar-Wind-Diesel Hybrid Energy System for a Coastal Area of Bangladesh

For sustainable development of a country access to electricity in every moment is now the basic need for the current civilization. Power crisis is one of the major barriers for economic development of Bangladesh. Bangladesh lacks in fossil fuel reservation. Abundance of renewable energy sources in the form of solar energy, wind energy provides opportunities of renewable energy based hybrid energy system in the coastal areas of Bnagladesh. Energy generation by hybrid system reduces the generation cost and will help in balancing the cost of energy. Again a standalone renewable enegy incorporated hybrid energy system will reduce load demand from the grid and will be an eco-friendly energy system. This paper proposed a cost effective design of standalone solar-wind-diesel hybrid power system in a coastal area of Bangladesh. Considering different conditions for a coastal area design and simulation of the hybrid power system was performed. Detailed economic analysis and comparison with solar based and diesel based energy system clearly reveals that proposed hybrid power system was found a cost effective solution for coastal areas of bangladesh.DOI:http://dx.doi.org/10.11591/ijece.v2i6.83

AlGaN/GaN HEMTにおける電流コラプスの機構と抑制

An AlGaN/GaN-based high-electron-mobility transistor (HEMT) is considered as an excellent candidate for future power devices due to its high breakdown voltage, high saturation drain current and low on-resistance (Ron). However, current collapse, i.e., dispersion of drain current or increased dynamic Ron, is regarded as one of the most critical issues to be solved for actual power-switching applications. Even though there have been remarkable improvements in growth and device technologies, it is still essential to understand mechanism of current collapse and ways to get rid of it. In this work, I have investigated the effect of passivation on current collapse in AlGaN/GaN HEMTs. A detailed analysis on trapping effects and localization of traps has been made. In order to suppress current collapse in AlGaN/GaN HEMTs, field plate (FP) structured devices have been studied. Drain current dispersion measurements have been performed for AlGaN/GaN HEMTs having different passivation films such as SiN and Al2O3. Passivated devices exhibited dispersion between static and pulsed current-voltage characteristics. The maximum drain current for SiN passivated devices was improved by around 25% at pulsed measurements as compared to its static value, whereas Al2O3 passivated devices exhibited that of around 56% deterioration. The drain current was decreased with increasing on-state duration time for SiN passivated devices, while it was increased for Al2O3 passivated devices. The mechanism responsible for the increase of drain current with on-state duration time by AlGaN surface traps is proposed, while GaN buffer traps reasonably govern the decrease of drain current. Effects of SiN passivation on current collapse have been studied by monitoring the dynamic change in Ron. The normalized dynamic Ron was decreased with increasing SiN-deposition temperature and became high with increasing off-state drain bias voltages. The normalized dynamic Ron was also decreased with increasing annealing temperature. These results indicate that the SiN/AlGaN interface trap density is reduced with increasing both SiN-deposition and annealing temperatures. Current collapse measurements have been performed for AlGaN/GaN HEMTs having identical breakdown voltages but with different FP lengths. The results indicated that applying more positive on-state gate biases resulted in pronounced recovery in the dynamic Ron for the FP device, whereas no gate-bias effects were observed for the device without FP. The mechanism responsible for the reduced current collapse by FP is proposed, in which the key role is played during on-state by the quick field-effect recovery of partial channel depletion caused by electron trapping at AlGaN surface states between gate and drain. The above studies indicate that the current collapse is suppressed by good passivation film and longer FP with more positive on-state gate biases in AlGaN/GaN HEMTs for future high-power applications
