The objectives of global transaction management in mul-tidatabase systems(MDBS) are to avoid the inconsistent retrievals and guarantee the global serializability under the existence of indirect connict which is unknown to to the global transaction manager(GTM). Many researches have shown that it is diicult to design the global concur-rency control method because of local autonomy. In these meth...

The aim of this study is to investigate the effects of outside board on rm value in Tehran Stock Exchange (TSE) from the perspective of information transaction costs. To do so, a sample of 96 firms listed in TSE is selected to be studied during the period of 2003-2012. Tobin q ratio is used to measure rm's value and bid-ask spread for information transaction costs. In addition to these variable...

this paper discusses the study of community’s preferences for biodiversity conservation management institution which may motivate them to support conservation efforts in the okwangwo division of the cross river national park, nigeria. the empirical data was generated from personal interviews and factors influencing the respondents’ choice were examined with the aid of multinomial logit mode...

  A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...

Genomic DNA extraction with a high quantity and quality is a basic requirement in molecular biology. The DNA obtained was free of any contamination proteins, polysaccharide, polyphenols and colored pigments. These compounds would interfere with the genomic isolation procedures and downstream reactions such as restriction enzyme analysis and gene amplification. The isolated genomic DNA was fo...

Modern programming languages provide features that allow a programmer to express concurrency in an application by using active objects, i.e. objects with their own thread of control, and distribution. Concurrent systems can be classified into cooperative systems, where individual components collaborate, share results and work for a common goal, and competitive systems, where the individual comp...

In this paper, a novel method for constructing complementary sequence set with zero correlation zone (ZCZ) is presented by interleaving and combining three orthogonal matrices. The constructed set can be divided into multiple sequence groups and each sequence group can be further divided into multiple sequence subgroups. In addition to ZCZ properties of sequences from the same sequence subgroup...
