Rapid genomic DNA extraction (RGDE)

Hyperpolymorphic short tandem repetitive DNA sequences, STRs or microsatellites, have become widely used in human identification, particularly in criminal cases and in mass disasters. In such cases the substrates for the analyses may be decomposed as a biological material, a fact that has to be taken into account when choosing the appropriate casework methods. Nowadays expanded windows have been opened to the world especially in the area of genetic and biology science by performance of big projects such as human genome project. In this regard, one of the primary and important steps for all is DNA extraction with high quality and quantity in minimum time from biological material. By using RGDE method, genomic DNA with high quality and quantity can be acquired in the shortest time which has been presented in the world up to now. In this paper we report the evaluation of DNA extraction in this method.     

A Conceptual Framework for Modeling Automated Negotiations in Multiagent Systems

In fully automated e‐negotiation all involved parties are software agents, so negotiation takes place in a multiagent system between software agents that have been developed as a computer system for automating tasks in a specific application domain. A multiagent system is a group of agents that interact and cooperate with each other to fulfill their objectives or to improve their performance. How do these agents negotiate with each other to manage their task interdependencies? What negotiation mechanisms are needed? These are important questions. In this article, we present a conceptual framework for modeling and developing automated negotiation systems. This framework represents and specifies all the necessary concepts and entities for developing a negotiation system as well as the relationships among these concepts. This framework can also be used to model human negotiations scenarios for analyzing these types of negotiations and simulating them with multiagent systems. The work reported in this article is the first unified framework that represents all the needed elements for modeling and developing automated negotiation systems and existing relationships between them.     

Impact of microcredit on income,poverty, and economic vulnerability in Peninsular Malaysia

This article examines the effect of Amanah Ikhtiar Malaysia's (AIM) microcredit programme on low-income households' income, poverty rate, and vulnerability in Peninsular Malaysia. This study employed a quasi-experimental approach, cross-sectional design, and stratified random sampling method. Findings indicated that participation in AIM's microcredit programme leads to an increase in household income and reduces both the poverty rate and level of economic vulnerability. AIM and policymakers, therefore, should focus on promoting a supportive environment to improve cooperation among participants by designing a dynamic and well-diversified microfinance programme and specialised skills-building training programme.     

An empirical testing of informational efficiency in Bangladesh capital market

We investigate how efficiently the stock market participants incorporate the information contained in money supply changes into stock prices in an emerging economy like Bangladesh. Of particular interest is to test how the changes in monetary aggregates directly affect the stock prices through asset changes and indirectly through their effects on real economic activity. We have considered the monthly series of the real stock returns (P) and examine the relationship between stock returns and monetary aggregates from 1980 to 2008. We also include the exchange rate of US dollar against Bangladeshi Taka and industrial production index. The presence of cointegration between stock prices and monetary aggregates indicate long-run predictability of the Bangladesh stock market. The short-run dynamics between monetary aggregates and real stock return, relied on theoretically motivated long-run restrictions, are analyzed using an empirical structural VAR model. The dynamic response of the real stock returns to changes in macroeconomic variables (such as broad money supply, exchange rates), particularly its lagged responses to real economic activity generates inefficiency in the Dhaka Stock Exchange. The findings of this article indicate that informational inefficiency exists in the stock market of Bangladesh due to the presence of unidirectional causality. To be efficient, the infrastructure of the SEC should be modernized, revaluation of the net asset value of the companies should be audited by the affiliated firms of the SEC, demutualization should be done as early as possible, private placement, issue of preference share and book building methods must be under rule based. Insider trading should be strictly prohibited.     

Public good provision in a repeated game: The role of small fixed costs of participation

Pecorino (1998) models tariff lobbying in a repeated game and finds that cooperation can be maintained in a large group, even though tariff lobbying provides a rival public good to interest group members. We add small fixed costs of participation to this model and find that cooperation must break down in large groups. By contrast, if a fully rival public good directly enters the utility function, then cooperation is possible in large groups, even with small participation costs. Thus, we find only partial support for Olson’s (1965) proposition that collective action must break down in large groups.     

Politics of administrative reform and reorganization in Bangladesh

The present military government in Bangladesh has implemented a number of major administrative reform and reorganization measures. The government claims that effectuation of such measures has led to the decentralization of power and authority to the grass-root level ensuring increasing popular participation in administration; the achievement of cost-effectiveness by reducing the number of ministries, divisions and personnel from the public pay roll and by quickening of the pace of decision-making due to elimination of redundant bureaucratic layers. But the implementation, in reality, has contributed among other things to the legitimization and strengthening of the military government, and a weakening of the democratically organized political opposition. It also enables generalist civil servants to preserve, and to some extent strengthen, their position within the civil service system.
