Field study on thermal comfort and adaptive strategies in residential buildings in China

This paper fully describes a nation-wide field study on building thermal environment and thermal comfort of occupant, which was carried out in summer 2005 and in winter 2006 respectively in China, illustrating the adaptive strategies adopted by occupants in domestic buildings in China. According to the climate division in China, the buildings in Beijing (BJ), Shanghai (SH), Wuhan (WH) and Chongqing (CQ), Guangzhou (GZ), Kunming (KM), were selected as targets which are corresponding to cold zone, hot summer and cold winter zone (SWC-SH, WH, CQ), hot summer and warm winter zone and temperate zone, respectively. The methodology used in the field study is the combination of subjective questionnaire regarding thermal sensation and adaptive approaches and physical environmental monitoring including indoor air temperature and relative humidity. A total of 1671 subjects participate in this investigation with more than 80% response rate in all surveyed cities. Both physiological and non-physiological factors (behavioural and psychological adaptations) have been analysed.

The sky is the limit? The determinants and constraints of European airports' commercial revenues

This study investigates the determinants of commercial and retail airport revenues as well as revenues from real estate operations. Cross-sectional OLS, 2SLS and robust regression models of European airports identify a number of significant drivers of airport revenues. Aviation revenues per passenger are mainly determined by the national income per capita in which the airport is located, the percentage of leisure travelers and the size of the airport proxied by total aviation revenues. Main drivers of commercial revenues per passenger include the total number of passengers passing through the airport, the ratio of commercial to total revenues, the national income, the share of domestic and leisure travelers and the total number of flights. These results are in line with previous findings of a negative influence of business travelers on commercial revenues per passenger. We also find that a high amount of retail space per passenger is generally associated with lower commercial revenues per square meter confirming decreasing marginal revenue effects. Real estate revenues per passenger are positively associated with national income per capita at airport location, share of intra-EU passengers and percent delayed flights. Overall, aviation and non-aviation revenues appear to be strongly interlinked, underlining the potential for a comprehensive airport management strategy above and beyond mere cost minimization of the aviation sector.

The financial system reform in China: the lesson learnt from the global financial crisis

This paper reviews the impact of the global financial crisis on financial system reform in China. Scholars and practitioners have critically questioned the efficiencies of the Anglo- American principal-agent model of corporate governance which promotes shareholder-value maximisation. Should China continue to follow the U.K.-U.S. path in relation to financial reform? This conceptual paper provides an insightful review of the corporate governance literature, regulatory reports and news articles from the financial press. After examining the fundamental limitations of the laissez-faire philosophy that underpins the neo-liberal model of capitalism, the paper considers the risks in opening up China’s financial markets and relaxing monetary and fiscal policies. The paper outlines a critique of shareholder-capitalism in relation to the German team-production model of corporate governance, promoting a “social market economy” styled capitalism. Through such analysis, the paper explores numerous implications for China to consider in terms of developing a new and sustainable corporate governance model. China needs to follow its own financial reform through understanding its particular economy. The global financial crisis might help China rethink the nature of corporate governance, identify its weakness and assess the current reform agenda.

Electricity use in the commercial kitchen

Academic and industrial literature concerning the energy consumption of commercial kitchens is scarce. Electricity consumption data were collected from distribution board current transformers in a sample of fourteen UK public house restaurants. This was set up to identify patterns of appliance use as well as to assess the total energy consumption of these establishments. The electricity consumption in the selected commercial kitchens was significantly higher than current literature estimates. On average, 63% of the premises electricity consumption was attributed to the catering activity. Key appliances that contributed to the samples average electricity consumption were identified as refrigeration (70 kwh, 41%), fryers (11 kwh, 13%), combi-ovens (35 kwh, 12%) bain maries (27 kwh, 9%) and grills (37kwh, 12%). Behavioral factors and poor maintenance were identified as major contributors to excessive electricity usage with potential savings of 70% and 45% respectively. Initiatives are required to influence operator behavior, such as the expansion of mandatory energy labeling, improved feedback information and the use of behavior change campaigns. Strict maintenance protocols and more appropriate sizing of refrigeration would be of great benefit to energy reduction.

The post-financial crisis challenges for corporate governance and banking reform in China

The purpose of this paper is to review the impact of the global financial crisis on banking reform in China. The significant doubt concerning the efficiencies of Anglo-American model of corporate governance has raised a critical political question amongst scholars and practitioners as to whether China should continue to follow the U.K.-U.S. path in relation to financial reform. This conceptual paper provides an insightful review of the corporate governance literature and regulatory reports. After examining the fundamental limitations of the laissez-faire philosophy that underpins the neo-liberal model of capitalism, which promotes greater liberalization and less control, the paper considers the risks in opening China’s financial markets and relaxing monetary and fiscal policies. A critique of shareholder-capitalism is outlined in relation to the German’s “social market economy” styled capitalism. Through such analysis the paper explores a number of implications for China to consider in terms of developing a new and sustainable corporate governance model applicable to the Chinese context.

Collective financing among Chinese entrepreneurs and department store retailing in China

Chinese entrepreneurship in department store retailing differed from that seen in other emerging economies before 1940. Rather than the leading examples of the format being owned by advanced economy firms, in China a small group of Cantonese entrepreneurs established what became known as the ‘Big Four’ department stores in Shanghai. By 1940 the ‘Big Four’ department stores were among the most famous stores in China, and among the biggest businesses in China. None of these Chinese entrepreneurs had any prior experience in department store retailing. Rather this article explains how their success in department store retailing was dependent on a business model that enabled these Chinese entrepreneurs to act as informal investment bankers (or ‘shadow’ banks) for the thousands of overseas Chinese wanting to invest surplus savings in mainland China, so creating large indigenous business groups.

Longitudinal scaling property of the charge balance function in Au plus Au collisions at root s(NN)=200 GeV

We present measurements of the charge balance function, from the charged particles, for diverse pseudorapidity and transverse momentum ranges in Au + Au collisions at root S(NN) = 200 GeV using the STAR detector at RHIC. We observe that the balance function is boost-invariant within the pseudorapidity coverage vertical bar-1.3, 1.3 vertical bar. The balance function properly scaled by the width of the observed pseudorapidity window does not depend on the position or size of the pseudorapidity window. This scaling property also holds for particles in different transverse momentum ranges. In addition, we find that the width of the balance function decreases monotonically with increasing transverse momentum for all centrality classes. (c) 2010 Elsevier B.V. All rights reserved.

Observation of the antimatter helium-4 nucleus

High-energy nuclear collisions create an energy density similar to that of the Universe microseconds after the Big Bang(1); in both cases, matter and antimatter are formed with comparable abundance. However, the relatively short-lived expansion in nuclear collisions allows antimatter to decouple quickly from matter, and avoid annihilation. Thus, a high-energy accelerator of heavy nuclei provides an efficient means of producing and studying antimatter. The antimatter helium-4 nucleus ((4)(He) over bar), also known as the anti-alpha ((alpha) over bar), consists of two antiprotons and two antineutrons (baryon number B = -4). It has not been observed previously, although the alpha-particle was identified a century ago by Rutherford and is present in cosmic radiation at the ten per cent level(2). Antimatter nuclei with B -1 have been observed only as rare products of interactions at particle accelerators, where the rate of antinucleus production in high-energy collisions decreases by a factor of about 1,000 with each additional antinucleon(3-5). Here we report the observation of (4)<(He) over bar, the heaviest observed antinucleus to date. In total, 18 (4)(He) over bar counts were detected at the STAR experiment at the Relativistic Heavy Ion Collider (RHIC; ref. 6) in 10(9) recorded gold-on-gold (Au+Au) collisions at centre-of-mass energies of 200 GeV and 62 GeV per nucleon-nucleon pair. The yield is consistent with expectations from thermodynamic(7) and coalescent nucleosynthesis(8) models, providing an indication of the production rate of even heavier antimatter nuclei and a benchmark for possible future observations of (4)(He) over bar in cosmic radiation.

Timing and structure of the 8.2 kyr BP event inferred from delta(18)O records of stalagmites from China, Oman, and Brazil

Oxygen isotope records of stalagmites from China and Oman reveal a weak summer monsoon event, with a double-plunging structure, that started 8.21 +/- 0.02 kyr B. P. An identical but antiphased pattern is also evident in two stalagmite records from eastern Brazil, indicating that the South American Summer Monsoon was intensified during the 8.2 kyr B. P. event. These records demonstrate that the event was of global extent and synchronous within dating errors of <50 years. In comparison with recent model simulations, it is plausible that the 8.2 kyr B. P. event can be tied in changes of the Atlantic Meridional Overturning Circulation triggered by a glacial lake draining event. This, in turn, affected North Atlantic climate and latitudinal position of the Intertropical Convergence Zone, resulting in the observed low-latitude monsoonal precipitation patterns.

Cationic and neutral phenylmercury(II) complexes with heterocyclic thione ligands. X-ray structures of [HgPh(dmpymtH)][BF(4)] center dot H(2)O and [{HgPh}(2)(mu-dtu)]

The neutral complex [HgPh(dmpymt)] 1 (dmpymtH = 4,6-dimethylpyrimidine-2(1H)-thione) reacts with HBF(4) to give the cationic complex [HgPh(dmpymtH)][BF(4)] 2. The X-ray molecular structure of the later revealed a [2+1] coordination sphere about the mercury(II) atom (C-Hg-S and Hg center dot center dot center dot N). In the dinuclear complex [(HgPh)(2)(mu-dtu)] 3 [dtuH(2) = 2,4(1H,3H)-pyrimidinedithione or dithiouracil] the coordination spheres are also [2+1] although dissimilar regarding the Hg center dot center dot center dot N secondary bonds. NMR spectroscopy ((1)H, (13)C and (199)Hg) studies were undertaken in solution and the results discussed in the light of the X-ray structures. (C) 2008 Elsevier B. V. All rights reserved.

Advocating at the margins: women’s NGOs in China

The development of non-governmental organizations (NGOs) in China has been unprecedented in the past fifteen years. The 1995 Fourth World Conference on Women (FWCW) and parallel NGO Forum in Beijing, China, opened the door for the first time for the establishment of women’s NGOs in China. This paper examines the development of Chinese women’s NGOs with a particular focus on two organizations in Beijing for marginalized female populations: one focusing on lesbians and the other helping women with HIV/AIDS. I examine the structure and growth of each NGO; however, on a more personal level and perhaps more importantly, I use the interviews I conducted with volunteers and clients of both organizations to analyze the importance of such organizations for lesbians and women living with HIV/AIDS. How have the lives of these women changed as a result of these particular organizations? What is their view regarding the support for lesbians and female HIV patients in China? These two case studies will shed light onto lesbians and women with HIV/AIDS in Beijing and the significance of such NGOs which function as the only support channels available for these two socially taboo communities.

Alternativas para a superação de obstáculos relativos à criação de valor, aumento da competitividade e acordos comerciais Internacionais na negociação comercial do Brasil com a China: o caso da soja

China and Brazil have got commercial potentials and strategic partnerships are desired from both sides, but in order to guarantee long term, stable relationship these countries must overcome barriers and obtain mutual gains. The objective of this study was to determine how one can overcome obstacles related to value creation, enhance of competitiveness and international deals in terms of Brazil-China commercial negotiation specifically for soy beans. The CEO of one of the biggest and most important international trading-companies has been contacted and mentioned problems faced by his company in terms of brazillian soy beans sale to chinese clients. Problems such as: the break up of legally based contracts, demanding public pressure, insufficient infra-structure in Brazil for production dispatching, cultural differences, lack of trust, power asymmetry were related and has been analyzed on this study. The perspective used on this study refers to elements, processes and forms of negotiation between these two continental giants.

Relações comerciais entre Brasil e China : uma análise de bem-estar a partir de um modelo de equilíbrio geral computável

O propósito deste trabalho é examinar possíveis ganhos de bem-estar provenientes de arranjos comerciais entre Brasil e China sob a ótica de um modelo de equilíbrio geral computável, o chamado “modelo GTAP” (sigla para Global Trade Analysis Project). Com base em uma descrição extensiva das estruturas econômicas e comerciais dos países e das Vantagens Comparativas de cada um deles, é possível simular acordos preferenciais de comércio e analisar os resultados de bem-estar por meio da medida de Variação Equivalente. Outro aspecto referente ao comércio sino-brasileiro que pode ser avaliado pela medida de bem-estar é o desalinhamento cambial dos dois países e as consequências deste para as transações comerciais entre ambos. Utilizando o mesmo ferramental anteriormente citado, o trabalho busca avaliar o impacto de tal desalinhamento no bem-estar dos países, uma vez que o câmbio seja corrigido via ajuste tarifário.

Aspectos do comércio entre China e Brasil e seus impactos

O presente trabalho tem como objetivo clarificar alguns pontos da relação comercial entre Brasil e China. Em grande parte é um trabalho descritivo, que utiliza diferentes agregações de produtos (Sistema harmônico; Broad Economic Categories), a fim de construir um cenário completo desta relação. Efeitos totais na produção brasileira, oriundos da demanda Chinesa por produtos Brasileiros também são analisados. Para tal utilizamos o ferramental de Matriz de Insumo Produto. Este efeito também é construído para o comércio do Brasil com os outros países do Mundo, e uma comparação é estabelecida. No fim do trabalho temos um estudo sobre possibilidades de comércio que ainda não foram exploradas entre esses dois países.

Efficacy evaluation of a commercial neem cake for control of Haematobia irritans on Nelore cattle

Muita atenção tem sido dada ao desenvolvimento de inseticidas vegetais buscando-se um efetivo controle de ectoparasitas de bovinos, sem prejudicar animais, consumidores e meio ambiente. Este estudo, realizado de abril a julho de 2008, na Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Pecuária Sudeste, em São Carlos, SP, Brasil, avaliou a eficácia de uma torta comercial de nim (Azadirachta indica) no controle da mosca-dos-chifres (Haematobia irritans) em bovinos. A torta de nim, misturada ao sal mineral na concentração de 2%, foi fornecida a 20 vacas Nelore, durante nove semanas, e sua eficácia foi monitorada através de contagens semanais nos grupos tratado e controle. Infestações individuais foram registradas por meio de fotos digitais em todos os animais de ambos os grupos, e o número de moscas foi, posteriormente, quantificado com o auxílio de um sistema de análise de imagem computadorizado. A quantificação dos componentes da torta de nim, por cromatografia líquida, revelou a presença de azadiractina (421 mg.kg-1) e 3-tigloyl-azadirachtol (151 mg.kg-1). A adição da torta de nim a 2% reduziu o consumo de sal mineral em cerca de 22%. O tratamento com torta de nim a 2% não reduziu as infestações por mosca-dos-chifres em bovinos durante as nove semanas do estudo.
