A Divergent Path of Industrial Upgrading: Emergence and Evolution of the Mobile Handset Industry in China

Starting from almost null in the late 1990s, China's mobile phone handset industry has grown to account for more than 40 percent of the current world production. While export growth has been overwhelmingly led by multi-national corporations (MNCs), increasingly fierce competition in the domestic market ignited by the advent of local handset makers has induced unique industrial evolution: (1) outgrowth of independent design houses specialized in handset development and (2) emergence of IC fabless ventures that design core ICs for handsets. In the background of this evolutionary industrial growth there are factors such as, the scale and increasing diversity of China's domestic market that advantages local firms vis-a-vis MNCs; modularization of handset and semiconductor technologies; policy interventions that supports local startups. The emergence and evolution of China's handset industry is likely to have international implications as the growth of the global demand for low-cost and multi-function mobile phone handsets is expected to accelerate. Thus, our case suggests that the conventional view of latecomer industrialization and upgrading that emphasizes the key role of international production networks organized by MNCs needs to be modified in order to accommodate China's rise into perspective.

Is the Vietnamese garment industry at a turning point? : upgrading from the export to the domestic market

Vietnam’s garment industry has been loosely characterized by the duality based on market orientation: export and domestic. Export-oriented garment suppliers were typically SOEs and foreign invested firms, while those producing for the domestic market have been mostly small, private companies. With a booming economy, other industrial sectors have emerged, and the garment industry is no longer the sector most favored by workers. Wage rates have been increasing, and a supplier’s ability to cope with this through successful upgrading has been the key determinant of whether it can further grow and flourish. Those who fail to cope are finding themselves in an increasingly difficult position. This paper looks at both the export- and domestic-oriented garment suppliers, and attempts to highlight how the industry can further develop by examining the bottlenecks that vary depending on the type of supplier. It suggests that in the long run, upgrading and value addition in the domestic market will be the key strategy.

Does trade liberalization boost quality upgrading? : evidence from Indonesian plant-product-level data

In this study, we examine the effects of tariff reduction on firms' quality upgrading by employing an Indonesian plant-product-level panel dataset matched with a plant-level dataset. We explore the effects of lower output and input tariffs separately, by focusing on the apparel industry. By estimating the Berry-type demand function, we derive product-quality indicators based on the Khandelwal (Review of Economic Studies, 2010) methodology, which enables us to isolate quality upgrading from changes in prices. Our findings are as follows. First, a reduction in output tariffs does not affect product quality upgrading. Second, a reduction in input tariffs boosts quality upgrading in general. In particular, this impact is greater for import firms, which is consistent with the fact that the source of the boost is the import of high-quality foreign inputs.

Energetic performance of landfill and digester biogas in a domestic cooker

The energetic performance of landfill biogas (LB) and biodigester biogas (BB) from municipal waste was examined in consumption tests. These tests were performed in situ at a gas generation plant associated with a landfill facility in Madrid (Spain) and following the standard UNE-EN 30-2-1 (1999). The jets of a domestic cooker commonly used for natural gas (NG) or liquefied petroleum gas (LPG) were modified to operate with the biogases produced at the facility. The working pressures best suited to the tested gases, i.e., to avoid flashback and flame lift, and to ensure the stability and correct functioning of the flame during combustion, were determined by trial and error. Both biogases returned optimum energetic performance for the transfer of heat to water in a metallic recipient (as required by the above standard) at a supply pressure of 10 mbar. Domestic cookers are normally supplied with NG at a pressure of 20 mbar, at which pressure the energetic performance of G20 reference gas was higher than that of both biogases (52.84% compared to 38.06% and 49.77% respectively). Data concerning these issues involving also unexplored feedstock are required for the correct conversions of domestic cookers in order to avoid risks of serious personal injuries or property damages.

Efecto de la variación en la cantidad de nitrógeno ligado a la fibra en piensos de cerdos sobre las características del purín resultantante y su potencial de NH3, Biogas y CH4: resusltados preliminares

La composición del purín varía en función de la dieta, los procesos fisiológicos y bioquímicos en el animal y el manejo, entre otros. La composición del purín es determinante en las emisiones de metano (CH 4 ) y amoniaco (NH 3 ) (Moset y col., 2012) y condiciona su aptitud para ser usado como fertilizante o como sustrato para la producción de biogás. Las materias primas comúnmente utilizadas en la fabricación de piensos poseen valores variables de nitrógeno ligado a fibra (N- FND) y determinadas combinaciones de ingredientes modifican de manera considerable la concentración de N-FND en los piensos. La ingesta de diferentes cantidades de N-FND puede dar lugar a cambios en la composición del purín y en su potencial de producción de NH 3 ,CH 4 y biogás. El objetivo del presente estudio fue evaluar los efectos de la modificación de la calidad del nitrógeno (N) en piensos de cebo en cerdos y sus implicancias en la producción de NH 3, CH 4 y biogás a partir del purín. Este ensayo es parte del proyecto GasPorc (AGL2011-30023-C03) que evalúa la relación que existe entre la composición de la dieta, características del purín y su potencial de producción de gases y valor fertilizante.

Hybridizing concentrated solar power (CSP) with biogas and biomethane as an alternative to natural gas: Analysis of environmental performance using LCA

Concentrating Solar Power (CSP) plants typically incorporate one or various auxiliary boilers operating in parallel to the solar field to facilitate start up operations, provide system stability, avoid freezing of heat transfer fluid (HTF) and increase generation capacity. The environmental performance of these plants is highly influenced by the energy input and the type of auxiliary fuel, which in most cases is natural gas (NG). Replacing the NG with biogas or biomethane (BM) in commercial CSP installations is being considered as a means to produce electricity that is fully renewable and free from fossil inputs. Despite their renewable nature, the use of these biofuels also generates environmental impacts that need to be adequately identified and quantified. This paper investigates the environmental performance of a commercial wet-cooled parabolic trough 50 MWe CSP plant in Spain operating according to two strategies: solar-only, with minimum technically viable energy non-solar contribution; and hybrid operation, where 12 % of the electricity derives from auxiliary fuels (as permitted by Spanish legislation). The analysis was based on standard Life Cycle Assessment (LCA) methodology (ISO 14040-14040). The technical viability and the environmental profile of operating the CSP plant with different auxiliary fuels was evaluated, including: NG; biogas from an adjacent plant; and BM withdrawn from the gas network. The effect of using different substrates (biowaste, sewage sludge, grass and a mix of biowaste with animal manure) for the production of the biofuels was also investigated. The results showed that NG is responsible for most of the environmental damage associated with the operation of the plant in hybrid mode. Replacing NG with biogas resulted in a significant improvement of the environmental performance of the installation, primarily due to reduced impact in the following categories: natural land transformation, depletion of fossil resources, and climate change. However, despite the renewable nature of the biofuels, other environmental categories like human toxicity, eutrophication, acidification and marine ecotoxicity scored higher when using biogas and BM.

Biogas from MSW landfill: Composition and determination of chlorine content with the AOX (adsorbable organically bound halogens) technique

An exhaustive characterization of the biogas from some waste disposal facilities has been carried out. The analysis includes the main components (methane, carbon dioxide, nitrogen and oxygen) as well as trace components such as hydrogen sulphide, ammonia and VOCs (volatile organic compounds) including siloxanes and halogenated compounds. VOCs were measured by GC/MS (Gas Chromatography/Mass Spectrometry) using two different procedures: thermal desorption of the Tenax TA and Carbotrap 349 tubes and SPME (Solid Phase Micro-Extraction). A method has been established to measure the total halogen content of the biogas with the AOX (adsorbable organically bound halogens) technique. The equipment used to analyze the samples was a Total Organic Halogen Analyzer (TOX-100). Similar results were obtained when comparing the TOX (Total Organic Halogen) values with those obtained by GC/MS. The halogen content in all the samples was under 22 mg Cl/Nm3 which is below the limit of 150 mg/Nm3 proposed in the Spanish Regulations for any use of the biogas. The low chlorine content in the biogas studied, as well as the low content of other trace compounds, makes it suitable for use as a fuel for electricity generating engines.

Presence of Siloxanes in the Biogas of a Wastewater Treatment Plant Separation in Condensates and Influence of the Dose of Iron Chloride on its Elimination

The siloxanes present in the biogas produced during anaerobic digestion damage the mechanism of cogeneration equipment and, consequently, negatively affect the energy valorization process. For this reason, the detection and elimination of these silicon-derived chemical compounds are a priority in the management of cogeneration facilities. In this regard, the objectives of this paper are, firstly, to characterize the siloxanes in the biogas and, secondly, to qualitatively evaluate the influence of the dose of iron chloride on its elimination. The research was performed at the Rincón de León Wastewater Treatment Plant (Alicante, Spain). The outflow biogas of the digesters and of the pressurized gasometers was sampled and analyzed. The results obtained made it possible to demonstrate, firstly, the absence of linear siloxanes and that, of the cyclic siloxanes, the predominant type was decamethylcyclopentasiloxane, and, secondly, that the addition of iron chloride in the digesters significantly reduces the siloxane content in the biogas. Additionally, it was demonstrated that the process of compression of the biogas, with the elimination of condensates, also produces significant reductions in the concentration of siloxanes in the biogas.

The UN General Assembly Vote: Upgrading the Status of Palestine and Its Implications for a Possible Role of the ICC. IES Policy Brief Issue 2013/06 • June 2013

On 29 November 2012, the General Assembly of the United Nations (UN) voted overwhelmingly to accord Palestine ‘Non-Member Observer State’ Status in the UN. In the first part of this Policy Brief, the implications of upgrading the status of Palestine with regard to the possible role of the International Criminal Court (ICC) will be assessed. In April 2012, the Office of the Prosecutor of the ICC declined to accept jurisdiction for acts committed on the territory of Palestine since 1 July 2002, justifying its decision based on the fact that Palestine had, at the time, only the status of an ‘Observer Entity’ at the UN. Subsequently, it will be analysed if the Palestinian pursuit of its cause before the ICC can be considered as an effective lawfare strategy or rather as a poisoned chalice.
