In a rapidly changing world, continuous adoption of new practices is crucial for survival; organizations embracing the latest technologies have a competitive edge. Smart organizations readily take on board new organizational forms and practices, those in particular that offer agility and responsiveness. The Internet and the World Wide Web offer a new way of collaboration via Web services, but heterogeneity of different service components make cooperation difficult. This chapter describes a new approach to combine Web services by employing a layered structure, in which composition of a value-added service can be built from individual components, and each service component can have semantically equivalent but syntactically different alternatives.

Ecological concerns have recently led to the increasing trend to upgrade carbon contained in waste streams into valuable chemicals. One of these components is acetate. Its microbial upgrading is possible in various species, with Escherichia coli being the best-studied. Several chemicals derived from acetate have already been successfully produced in E. coli on a laboratory scale, including acetone, itaconic acid, mevalonate, and tyrosine. As acetate is a carbon source with a low energy content compared to glucose or glycerol, energy- and redox-balancing plays an important role in acetate-based growth and production. In addition to the energetic challenges, acetate has an inhibitory effect on microorganisms, reducing growth rates, and limiting product concentrations. Moreover, extensive metabolic engineering is necessary to obtain a broad range of acetate-based products. In this review, we illustrate some of the necessary energetic considerations to establish robust production processes by presenting calculations of maximum theoretical product and carbon yields. Moreover, different strategies to deal with energetic and metabolic challenges are presented. Finally, we summarize ways to alleviate acetate toxicity and give an overview of process engineering measures that enable sustainable acetate-based production of value-added chemicals.

<p>Coconut export sector in India of late gained an outward orientation, especially since the Coconut Development Board was elevated to the status of export promotion council in the year 2009. In the recent period, the growth rate experienced in the coconut based value added products has been stupendous. Since there is an attempt for global value chain up-gradation at the production node of the sector, it is imperative to analyse our strengths in the world market in comparison with the major competitors. We have used the Revealed Comparative Advantage (RCA) methodology to analyse India’s competitiveness in the exports of major coconut value added products traded across the world. The study revealed that, as far as the coconut value added products are concerned, India is comparatively a very small player with paltry export market shares. The analysis of RCA revealed that comparative advantage of India is lower than the major coconut exporting countries like Philippines, Indonesia and Sri Lanka. The Philippines is the dominant player with highest RCA indices in most of the coconut value added product lines. The study suggests the need to formulate plausible strategies to reach the overseas market and capture the optimal share in market segments. Though we have a strong domestic market base, it is an indubitable fact that in the near future due to the evolving trade agreements even in the domestic sector we may confront fierce price competition from the overseas imports. Hence we need to chalk out modalities and execution plans to elevate our export competitiveness and comparative advantage.</p>

Trade In Value Added

Purpose – The purpose of this paper is to extricate value-added exports in information and communications technology (ICT) industry earned by Taiwan and Korea. Additionally, the authors decompose Taiwan and Korea’s gross exports into various meaningful components. Design/methodology/approach – The authors use the inter-country input-output (ICIO) table which endows with cost structures of industries as well as trade information, facilitating in keeping track of the flow of products and value-added. The ICIO table used in this paper comes from the World Input-Output Database. The authors also use the way Wang et al. (2013) decomposed the intermediate goods exports into various components to provide further insights. Findings – The empirical results indicate that Taiwan and Korea’s ICT export to the world shrink by 47.8 and 40.9 percent when the trades are measured in value-added terms. Taiwan and Korea’s ICT export will also decrease by 75.1 and 57.8 percent. From the viewpoint of value added in trade, the share of value added embodied in Taiwan and Korea’s gross ICT exports continued to decrease and reached 24.9 and 42.2 percent in 2011, while the components of pure double counted terms kept growing in recent years. Originality/value – With global value chains flourishing in recent years, conventional trade statistics not only fails to highlight the vertical specialization among different countries, but also distorts the measurement of a country’s competitiveness. This paper extricates value-added exports in ICT industry earned by Taiwan and Korea and bring into focus the importance of trade in value added.

Energy crisis and continuously fluctuating cost of petroleum have move attention of researchers toward renewable and sustainable energy sources and materials. Biomass or bioresources is one of the abundant and cheap renewable energy sources and materials that is environment friendly in Malaysia and other tropical countries in the world. It has been identified as one of the main sources of the sustainable energy in the fifth fuel strategy in Malaysia. This paper describes several possible routes to provide energy as well as potential value-added products from bioresources. The future trend in thermo-conversion processing of the biomass is the utilization of microwave energy into renewable bio-fuels, materials and chemicals. The potential of uses of bio-oils and bio-chars from oil palm solid wastes for biofuels, materials and chemicals are given. The applications of these renewable sources to produce biofuels, materials and chemicals have been applied in some countries around the world. The implementation of the biomass technology will be best utilized and feasible when the technology is developed locally, fabricated and commission with the utilization of locally produced biomass. With the research and development efforts developed locally towards local expertise will help to produce indigenous technologies, thus reducing the high cost of import technology.

Refrigeration Storage

One of the most popular seafood in the world is shrimp, including cooked shrimp. Boiled shrimp is a value added product with high protein content, specific taste, ready to eat, and have an interested colour for consumers. Boiled shrimp must be protected from quality deterioration during storage. The research was carried out to study the effect of carrageenan coating to inhibit the quality deterioration of boiled shrimp based on organoleptic evaluation during refrigeration storage (4-6oC). Peeled undevined (PUD) vannamei (Litopenaeus vannamei) with size 60-70 was used as object. The boiled shrimps treated with two treatmens, which were coated and uncoated boiled shrimps. Application of coating carrageenan on boiled shrimp indicate that coating application could extend its shelf life, proved by higher organoeptic value than uncoated product, based on organoleptic evaluation for frozen boiling shrimp (SNI 01-2346-2006).
