The Role of the Namayande in Iran's Textile Industry

The Iranian textile industry still remains important as one of the largest sources of employment within the non-petroleum sector, although it no longer plays the large role it used in the country's economy (having been replaced by petroleum as the economy's primary industry). The subject of this study are middlemen known as namayande in the Iranian textile industry who plays a very important role in the operations of the innumerable small and medium-sized private firms. When private firms import materials from abroad, namayande make the connections between them and foreign sellers. These middlemen are not local sales agents of foreign companies as is usually the case; rather the namayande specialize in purchasing goods for local buyers. This study will point out some of the reasons why the namayande exist, and examine the present state of Iran's textile industry along with the particular management problems found within the firms' operations.

Export-Led Growth and Geographic Distribution of the Poultry Meat Industry in Brazil

This paper includes an examination of the sustainability of recent high growth in the poultry meat industry in Brazil. In addition, an assessment is made of the impact of increased production of poultry meat products on the development of local industries. Comparative studies of leading companies in the United States, Mexico, and Brazil reveal competitive advantages in the low costs of feedstuff and labor as well as disadvantages in the scale of business and management efficiency in the Brazilian poultry sector. Increases in domestic and foreign demand for Brazilian poultry meat have promoted development of the Brazilian poultry sector in local areas. The formation of industrial clusters is observed using regional data related to the location of slaughterhouses and the number of chickens farmed. Statistical analyses support observations made in this paper.

Local Firms in Latecomer Developing Countries amidst China's Rise -The case of Vietnam's motorcycle industry-

This paper examines the impact of China's recent rise on the development of local firms in latecomer developing countries. Based on a detailed analysis of Vietnam's motorcycle industry, the paper argues that China's impact may go beyond what a trade analysis suggests. Indeed, China's rise induced a dynamic transformation in the structure of value chains within Vietnam's motorcycle industry, bringing about far-reaching consequences on the development and upgrading trajectories of local firms. The implications of the case study for the wider "global value chain" approach is also discussed.

Empirical global value chain analysis in electronics and automobile industries :An application of Asian international input-output tables

This study aims to examine the international value distribution structure among major East Asian economies and the US. The mainstream trade theory explains the gains from trade; however, global value chain (GVC) approach emphasises uneven benefits of globalization among trading partners. The present study is mainly based on this view, examining which economy gains the most and which the least from the East Asian production networks. Two key industries, i.e., electronics and automobile, are our principle focus. Input-output method is employed to trace the creation and flows of value-added within the region. A striking fact is that some ASEAN economies increasingly reduce their shares of value-added, taken by developed countries, particularly by Japan. Policy implications are discussed in the final section.

Shock Transmission Mechanism of the Economic Crisis in East Asia : An Application of International Input-Output Analysis

This paper investigates the impacts of the 2008 economic crisis on industries in East Asia. By using the updated Asian international input-output table for 2008, the paper attempts to identify the transmission mechanism and the magnitude of impact of the crisis on industries in East Asia. The analyses reveal that the crisis significantly affected industrial output of the nine East Asian countries. In particular, the countries which are deeply involved in production networks were affected most seriously. Moreover, the analyses show that the impact was transmitted to East Asian industries considerably through the “triangular trade”, in which China imports parts and components from neighboring East Asian countries and then exports final products to the U.S. and EU markets.

Application of protection means against explosions in underground mines

Underground coal mines explosions generally arise from the inflammation of a methane/air mixture. This explosion can also generate a subsequent coal dust explosion. Traditionally such explosions have being fought eliminating one or several of the factors needed by the explosion to take place. Although several preventive measures are taken to prevent explosions, other measures should be considered to reduce the effects or even to extinguish the flame front. Unlike other protection methods that remove one or two of the explosion triangle elements, namely; the ignition source, the oxidizing agent and the fuel, explosion barriers removes all of them: reduces the quantity of coal in suspension, cools the flame front and the steam generated by vaporization removes the oxygen present in the flame. The present paper is essentially based on the comprehensive state-of–the-art of Protective Systems in underground coal mines, and particularly on the application of Explosion Barriers to improve safety level in Spanish coal mining industry. After an exhaustive study of series EN 14591 standards covering explosion prevention and protection in underground mines, authors have proven explosion barriers effectiveness in underground galleries by Full Scale Tests performed in Polish Barbara experimental mine, showing that the barriers can reduce the effects of methane and/or flammable coal dust explosions to a satisfactory safety level.

Toward functional genomics in bacteria: Analysis of gene expression in Escherichia coli from a bacterial artificial chromosome library of Bacillus cereus

As the study of microbes moves into the era of functional genomics, there is an increasing need for molecular tools for analysis of a wide diversity of microorganisms. Currently, biological study of many prokaryotes of agricultural, medical, and fundamental scientific interest is limited by the lack of adequate genetic tools. We report the application of the bacterial artificial chromosome (BAC) vector to prokaryotic biology as a powerful approach to address this need. We constructed a BAC library in Escherichia coli from genomic DNA of the Gram-positive bacterium Bacillus cereus. This library provides 5.75-fold coverage of the B. cereus genome, with an average insert size of 98 kb. To determine the extent of heterologous expression of B. cereus genes in the library, we screened it for expression of several B. cereus activities in the E. coli host. Clones expressing 6 of 10 activities tested were identified in the library, namely, ampicillin resistance, zwittermicin A resistance, esculin hydrolysis, hemolysis, orange pigment production, and lecithinase activity. We analyzed selected BAC clones genetically to identify rapidly specific B. cereus loci. These results suggest that BAC libraries will provide a powerful approach for studying gene expression from diverse prokaryotes.
