Loess magnetic properties in the Ili Basin and their correlation with the Chinese Loess Plateau

     Over the past two decades, magnetoclimatological studies of loess-paleosol sequences in the Chinese Loess Plateau (CLP) have made outstanding achievements, which greatly promote the understanding of East Asian paleomonsoon evolution, inland aridification of Asia, and past global climate changes. Loess magnetic properties of the CLP have been well studied. In contrast, loess magnetic properties from outside the CLP in China have not been fully understood. We have little knowledge about the magnetic properties of loess in the Ili Basin, an intermontane depression of the Tianshan (or Tien Shan) Mountains. Here, we present the results of rock magnetic measurements of the Ili loess including mass magnetic susceptibility (χ) and anhysteretic remanent magnetization (ARM), high/low temperature dependence of susceptibility (TDS) and hysteresis, as well as X-ray diffraction (XRD) for mineral analysis. Based on the comparison with loess-paleosol sequences in the CLP (hereafter referred to as the Chinese loess), we discuss the possible magnetic susceptibility enhancement mechanism of the Ili loess. The results show that 1) the total magnetic mineral concentration of the Ili loess is far lower than that of the Chinese loess, though they have similar magnetic mineral compositions. The ferrimagnetic minerals in the Ili loess are magnetite and maghemite, and the antiferromagnetic mineral is hematite; XRD analysis also identifies the presence of ilmenite. The ratio of maghemite is lower in the Ili loess than in the Chinese loess, but the ratios of magnetite and hematite are higher in the Ili loess than in the Chinese loess. 2) The granularity of magnetic minerals in the Ili loess, dominated by pseudo-single domain (PSD) and multi-domain (MD) grains, is generally much coarser than that of the Chinese loess. Ultrafine pedogenically-produced magnetic grains have a very limited contribution to the susceptibility enhancement. Rather, PSD and MD particles of magnetite and maghemite are the main contributors to the enhancement of susceptibility in the Ili loess. 3) The susceptibility enhancement mechanism for the Ili loess is complicated and superimposes both a wind velocity/vigor model (Alaskan or Siberian model) and the in situ ultrafine grain pedogenic model; the former might play an important role in the Ili loess. 4) Magnetic susceptibility enhancements of the Ili loess are related not only to the eolian input of the source area, but also to the local climate, landform, and geological background. Therefore, great care should be taken when reconstructing paleoclimate using magnetic susceptibility data from the Ili loess.

Industrial development and land use/cover change and their effects on local environment: a case study of Changshu in eastern coastal China

The interactions among industrial development, land use/cover change (LUCC), and environmental effects in Changshu in the eastern coastal China were analyzed using high-resolution Landsat TM data in 1990, 1995, 2000, and 2006, socio-economic data and water environmental quality monitoring data from research institutes and governmental departments. Three phases of industrial development in Changshu were examined (i.e., the three periods of 1990 to 1995, 1995 to 2000, and 2000 to 2006). Besides industrial development and rapid urbanization, land use/cover in Changshu had changed drastically from 1990 to 2006. This change was characterized by major replacements of farmland by urban and rural settlements, artificial ponds, forested and constructed land. Industrialization, urbanization, agricultural structure adjustment, and rural housing construction were the major socio-economic driving forces of LUCC in Changshu. In addition, the annual value of ecosystem services in Changshu decreased slightly during 1990-2000, but increased significantly during 2000-2006. Nevertheless, the local environmental quality in Changshu, especially in rural areas, has not yet been improved significantly. Thus, this paper suggests an increased attention to fully realize the role of land supply in adjustment of environment-friendly industrial structure and urban-rural spatial restructuring, and translating the land management and environmental protection policies into an optimized industrial distribution and land-use pattern.

What are the local impacts of energy systems on marine ecosystem services: a systematic map protocol

Background: Increasing concentrations of atmospheric greenhouse gases (GHG) and its impact on the climate has resulted in many international governments committing to reduce their GHG emissions. The UK, for example, has committed to reducing its carbon emissions by 80% by 2050. Suggested ways of reaching such a target are to increase dependency on offshore wind, offshore gas and nuclear. It is not clear, however, how the construction, operation and decommissioning of these energy systems will impact marine ecosystem services, i.e. the services obtained by people from the natural environment such as food provisioning, climate regulation and cultural inspiration. Research on ecosystem service impacts associated with offshore energy technologies is still in its infancy. The objective of this review is to bolster the evidence base by firstly, recording and describing the impacts of energy technologies at the marine ecosystems and human level in a consistent and transparent way; secondly, to translate these ecosystem and human impacts into ecosystem service impacts by using a framework to ensure consistency and comparability. The output of this process will be an objective synthesis of ecosystem service impacts comprehensive enough to cover different types of energy under the same analysis and to assist in informing how the provision of ecosystem services will change under different energy provisioning scenarios. Methods: Relevant studies will be sourced using publication databases and selected using a set of selection criteria including the identification of: (i) relevant subject populations such as marine and coastal species, marine habitat types and the general public; (ii) relevant exposure types including offshore wind farms, offshore oil and gas platforms and offshore structures connected with nuclear; (iii) relevant outcomes including changes in species structure and diversity; changes in benthic, demersal and pelagic habitats; and changes in cultural services. The impacts will be synthesised and described using a systematic map. To translate these findings into ecosystem service impacts, the Common International Classification of Ecosystem Services (CICES) and Millennium Ecosystem Assessment (MEA) frameworks are used and a detailed description of the steps taken provided to ensure transparency and replicability.

WTO government procurement rules and the local dynamics of procurement policies: A malaysian case study

This article examines efforts to create binding international rules regulating public procurement and considers, in particular, the failure to reach a WTO agreement oil transparency in government procurement. The particular focus of the discussion is the approach taken by Malaysia to these international procurement rules and to the negotiation of an agreement on transparency. Rules governing public procurement directly implicate fundamental arrangements of authority amongst and between different parts of government, its citizens and non-citizens. At the same time, the rules touch upon areas that are particularly sensitive for some developing countries. Many governments use preferences in public procurement to accomplish important redistributive and developmental goals. Malaysia has long used significant preferences in public procurement to further sensitive developmental policies targeted at improving the economic strength of native Malays. Malaysia also has political and legal arrangements substantially at odds with fundamental elements of proposed global public procurement rules. Malaysia has, therefore, been forceful in resisting being bound by international public procurement rules, and has played all important role in defeating the proposed agreement oil transparency. We suggest that our case study has implications beyond procurement. The development of international public procurement rules appears to be guided by many of the same values that guide the broader effort to create a global administrative law. This case study, therefore, has implications for the broader exploration of these efforts to develop a global administrative law, in particular the relationship between such efforts and the interests of developing countries.

Spectacle design preferences among Chinese primary and secondary students and their parents: A qualitative and quantitative study

Purpose: To identify the specific characteristics making glasses designs, particularly those compatible with adjustable glasses, more or less appealing to Chinese children and their parents. Patients and Methods: Primary and secondary school children from urban and rural China with < = -1.00 diopters of bilateral myopia and their parents ranked four conventional-style frames identified by local optical shops as popular versus four child-specific frames compatible with adjustable spectacles. Scores based on the proportion of maximum possible ranking were computed for each style. Selected children and their parents also participated in Focus Groups (FGs) discussing spectacle design preference. Recordings were transcribed and coded by two independents reviewers using NVivo software. Results: Among 136 urban primary school children (age range 9-11 years), 290 rural secondary school children (11-17 years) and 16 parents, all adjustable-style frames (scores on 0-100 scale 25.7-62.4) were ranked behind all conventional frames (63.0-87.5). For eight FGs including 12 primary children, 26 secondary children and 16 parents, average kappa values for NVivo coding were 0.81 (students) and 0.70 (parents). All groups agreed that the key changes to make adjustable designs more attractive were altering the round lenses to rectangular or oval shapes and adding curved earpieces for more stable wear. The thick frames of the adjustable designs were considered stylish, and children indicated they would wear them if the lens shape were modified. Conclusions: Current adjustable lens designs are unattractive to Chinese children and their parents, though this study identified specific modifications which would make them more appealing.

Corrupção e poder local: transparência dos sítios web: estudo de caso

O presente trabalho versa sobre a temática da corrupção como fenómeno global e a sua influência nas mais diversos setores da atividade politica, social e económica. A sua prevenção e combate tem sido objeto das mais variadas intervenções a nível mundial, através da criação de organismos e mecanismos legais. No contexto nacional, esta problemática tem feito parte das políticas governamentais de vários governos, através da adoção dos vários mecanismos internacionais ratificados e transpostos para o ordenamento jurídico interno português, ao abrigo dos quais foram criados mecanismos de foro institucional e legislativo, como forma de tornar a sua atuação cada vez mais transparente. Entendemos realizar este estudo na perspetiva do poder local (municípios) e respetivos sítios web e tendo em conta que a informação é o pilar de uma Administração aberta e transparente aos cidadãos, quer na sua atuação, quer na sua responsabilização. Propõe-se neste estudo observar como se refletem as diversas imposições legislativas em matéria de informação (produção e publicidade) e demais mecanismos, na atuação dos municípios, sob ponto de vista da sua implementação nos sítios web. Para tal recorremos à vasta matéria legislativa existente e delineamos a nossa investigação ao abrigo da questão principal formulada, para qual propusemos algumas hipóteses de investigação, que nos propusemos aferir pela observação e análise on-line ao sítio web definido. As conclusões indicam que as questões de transparência e informação são o objetivo primordial de qualquer Administração aberta e responsável, cujo objetivo seja a prossecução do interesse público. Para além disso, constata-se que os diversos mecanismos legislativos constituem forte comprometimento na sua implementação, bem como condicionam a atuação dos decisores públicos em termos de desvios de comportamento e responsabilização.

中国四个城市吸引海外回流人才比较研究：一个政策的视角 (Returned highly skilled migrants in four Chinese cities: a policy perspective)

Most studies of returned highly skilled migrants in China were guided by a national approach, emphasizing how the size and direction of the return migration were shaped by national policies and practices. What have been overlooked are the flows of returned skills at the municipal level where talent attraction and employment really take place. To fill this gap, the author conducted a comparative study of the returned highly-skilled migration in Beijing, Shanghai, Guangzhou and Shenzhen, the four most important cities in China. Based on in-depth interviews with returned skills from different countries and with various occupational backgrounds, complemented by the analysis of talent policies that have been issued by each city since the early 1990s and relevant statistical data, this study finds that, first, municipal cities tend to make ‘localized policies’ in order to suit local situation and to increase flexibility and efficiency in their effort of enticing of talents, demonstrating a wide range of variations not yet discussed in previous literature. It is thus crucial to pay timely attention to municipalities in order to obtain a more accurate and balanced picture of returned skilled migration in China. Second, the flow of returned skills shall be perceived in a broader analytical framework, in which the attractiveness to skills comes mostly from the long-term career potentials made possible by the industrial structure of individual city and mediated by social, cultural and geographical factors. It is only within this larger framework and through the interaction with other factors that government policies play their modulator roles.

The stamp of identities: negotiating diasporic Chinese subjectivity in philatelic spaces

This paper examines the politics and poetics of identity construction and articulation among guiqiao (Returned Overseas Chinese) through a case study of a postage stamp exhibition put up jointly by an ordinary guiqiao and an official huaqiao (Overseas Chinese) museum in Quanzhou, China. Two conflicting meaning systems are identified in this exhibition. On the surface and mainly through words, it promulgates a highly clichéd China-centred discourse of huaqiao as patriotic subjects, legitimated by the authority of an official museum. Simultaneously, it articulates implicitly a “trans-local diasporic subjectivity” conveyed by the imagery of stamps and constituted by constant interactions between the materiality of stamps and the bodily experience of stamp collectors beyond the museum. This study contributes to the study of guiqiao, and of Chinese diaspora in general, in two ways. First, it complicates the conventional understanding of guiqiao identity by pinpointing contested negotiations between the state from above and guiqiao from below, involving simultaneously conflicts and compromises. Secondly, it brings to light the important role of body, affect and materiality in the construction and articulation of guiqiao identities, paving the way for integrating museum and migration studies with the potential to re-conceptualize transnational mobilities in the Chinese context and beyond.

Drivers of Local Firms’ Focus on Internal R&D in Emerging Economies and Their International Performance

Grounded on the resource-based view of the firm, the study of this thesis investigates the effect of four internal and external factors – engineer intensity, location, affiliation with the government, government funding – on Chinese firms’ decision to either invest in internal R&D activities or external R&D and the effect of this decision on the firms’ international market success. In addition, the moderating role of the presence of foreign firms in China is examined. To understand these relationships, the thesis’ theorization focuses on the issue of how firms can combine optimally the two options – “internal R&D” and “external R&D”. In this regard I juxtapose internal R&D and external R&D and compare their advantages and disadvantages. To test my model, I apply panel data from the Annual Industrial Survey Database provided by the Chinese National Bureau of Statistics. My results show that three of the four investigated factors affect Chinese firms’ resource allocation decisions; and effective resource allocation decisions lead effectively to international market success, strengthened by the presence of foreign firms in China. Moreover the findings bear several theoretical and managerial contributions. First I propose the last dimension of the “VRIO framework” – “organization” – as an endogenous component of the VRIO framework, as my study investigated how firms can effectively combine resources to generate a competitive advantage in terms of international market success. Previous academic literature so far focused on examining whether internal and external R&D are complements or substitutes. My study fills a gap in the literature by investigating the determinants of the efficient combination of the two strategies and the outcome of the combination. One of the managerial implications is that Chinese firms can learn from foreign companies that are present in China.

Governments and the Decentralization

The Purpose of This Article Is to Show How Costs and Benefits of Geographical Decentralization of R&D Can Be Identified and Compared. the Benefits for the Region That Receives R&D Activities Are Studied in Section 1. They Stem From the Short-Run Multiplier Effect, the Amelioration of Human Capital and the Possible Modernization of the Local Industrial Structure. on the Cost Side Examined in Section 2, the Observable Impacts of the Decentralization of R&D Concern the Loss of Returns to Scale and of the Production of the R&D Output. It Is Shown, in Section 3, That the Flows of Costs and Benefits Must Be Discounted by the Social Cost of Capital. the Main Conclusion of This Article Is That the Decentralization of R&D in a Large Sparsely Populated Country Entails Social Cost and Would Weaken Its Competitive Position in World Commerce. on the Other Hand, the Issue of Decentralization Is More Crucial for Small Countries (In Terms of Population and Economic Size) Than for Large Ones, Like the U.S., Where Critical Masses of Research Efforts Cna Be Simulataneously Attained in Many Fields and in Many Places.

Local food security initiatives: systemic limitations in Vancouver, Canada

This paper approaches the topic of urban/community gardening not through the lens of urban theory per se but in light of basic farming realities such as growing season and land availability. Food security comprises availability and affordability. In the context of North American and Western European societies, only food affordability normally merits public discourse. In practice, governments have little or no means to change food affordability, in view of prevailing capitalistic free-market structures. In the current wave of popular exuberance, civic politicians and others have promoted the belief that community gardening could be the pathway to produce affordable food. The formidable obstacles to this pursuit include the availability of (low-cost) land within the highly-densified city limit, insufficient ambient temperature and water supply during the growing season and the contemporary structure of society. Overcoming these fundamental hurdles carries significant negative environmental and economic consequences.
