城市地价空间自相关分析——以宿州市为例

运用全局和局域自相关统计量及地统计学半变异函数分析方法,对宿州市商业和住宅地价的全局自相关、各项异性及局域自相关特征进行了全面分析.结果表明:在2 800m范围内,宿州市商业和住宅地价均存在较强的正自相关性且趋于高值集聚,随着相关距离的增大,地价半方差按球状模型曲线增长,自相关性逐渐减弱;在不同方向上,地价的空间自相关特征不尽相同,南北方向上的空间自相关范围要大于东西方向,但随机性较强,自相关程度较东西方向弱;在全局呈显著自相关的情形下局域地价也主要呈空间集聚格局,但部分地区表现出异质性.

Performative global finance: bridging micro and macro approaches with a stratified perspective

Theories of performativity can enhance the study of global finance. Taking everyday financial practices seriously, they emphasise the potentially structuring effects and disciplinary nature of finance, and foreground the performative role of economics, financial models, and formulas. It has remained largely overlooked to date that the literature on the performativity of finance can be divided into two distinct approaches. ‘Microperformativity’ is the more actor-oriented approach, beginning its analysis with the exploration of agencements and their practices, or the examination of the social history of mathematical formulas in finance. ‘Macroperformativity’, in contrast, takes its point of departure from the social structure of finance itself, often in relation to national, international, or global power structures. Neither approach provides for an intermediary concept that more explicitly links the micro and macro level. Nor does either approach give adequate analytical consideration to social conflicts and power struggles. To fill these gaps, the paper applies poststructural hegemony theory to reconceptualise performativity as an articulatory logic which accounts for the transition of a particularity towards a universality within a framework of stratified hegemony. Framed accordingly, the concept of performativity accounts more strongly for the social and political processes, ruptures, contestations and contradictions in global finance.     

Global and Euro Imbalances： China and Germany

We analyze global and euro area imbalances by focusing on China and Germany as large surplus and creditor countries. In the 2000s, domestic reforms expanded the effective labor force, restrained wages, shifted income toward profits and increased corporate saving. As a result, the Chinese and German current account surpluses widened, and that of Germany has proven more persistent, with subdued domestic investment. China is an early-stage creditor, holding a short equity position and a longposition in safe debt. Germany＇s balanced net debt and equity claims mark it as a mature creditor thatprovides insurance to the rest of the world. China pays to lay off equity risk, while Germany, by contrast, harvests a moderate yield on its net claims. In both economies, the shortfall of the net international investment position from cumulated current account surpluses arises from exchange rate changes, asymmetric valuation gains, and, in Germany＇s case, credit losses.     

Consumer engagement with brands on social network sites: A cross-cultural comparison of China and the USA

To advance theoretical understanding of consumer engagement on social media, this cross-cultural study evaluates how culture influences consumers’ engagement levels and activities on brand pages of social network sites. It further evaluates the underlying motivations and engagement mechanisms in two culturally distinct countries, China and the USA. Specifically, social media dependency, parasocial interaction, and community identification are examined as the key antecedents of consumer-brand engagement. The results confirm the effects of the proposed antecedents and reveal both cultural differences and similarities between Chinese and American consumers’ engagement with brand pages on social network sites.

Comparison of Methods for Evaluation of the Convolution of Two Compound R 1 Distributions

In the present paper we compare four methods for evaluating the convolution of two compound R 1 distributions by counting the numbers of elementary algebraic operations required. Two of the methods are applicable in general, whereas the remaining two are restricted to the case when the two compound distributions have the same severity distribution. This case is discussed separately. We consider in particular the special case when this common severity distribution is concentrated in one, that is, evaluation of the convolution of two R 1 distributions.     

Antecedents of Global Attitude

Abstract

The term “globalization” has recently been used to explain multiple world trends. Such trends include worldwide accessibility to the same products, access to the same resources around the globe, world travel, communication, convergence of lifestyles, development of “world culture,” and worldwide fascination with environmental issues. This paper explores the population's attitude towards globalization (global attitude) and investigates antecedents that affect the level of global attitude. The antecedents examined are population's current satisfaction, opinion of governance, and future expectations. Results from structural equation modeling show that current satisfaction with life and opinion of governance have a positive and significant influence on development of global attitude.     

Educating the Global Manager

Abstract

The culturally diverse classroom would seem to be the ideal resource that educators can tap to develop their students' cross-cultural competence and bridge different cultures. However, evidence from the education literature suggests that students typically do not benefit from classroom diversity and that, in general, there is a lack of cross-cultural interactions between different cultural groups on campus. In this paper, we provide an integrated framework for developing students' cross-cultural competence by drawing on the cultural diversity in the classroom. The framework incorporates established and frequently used strategies for developing cross-cultural competence, as well as additional strategies that we have devised (such as diversity audits, self-awareness and ‘other’-awareness tools, student-generated cases and virtual linkages). We explain how this approach uses cultural diversity inherent in the classroom as a basis for students' awareness and understanding of cultural differences, knowledge of other cultures and the application of skills.     

Are tourism impacts low on personal environmental agendas?

This paper examines if tourism is an environmental priority for tourism and hospitality students. It is framed within the context of information and choice overload that may result in the need to prioritize issues and make less effective decisions. A series of open-ended questions identified the most important community and global environmental issues, the single greatest cause of climate change and whether students had changed their behaviour in general, or their travel behaviour in particular, to reduce their environmental impact. A total of 2968 useable surveys were returned from students at 63 institutions in 22 economies. Tourism emerged as a low priority issue, which explains why only a small proportion of students had changed their travel behaviour. Moreover, the study noted high knowledge variability, which in turn was closely associated with the type of actions undertaken. Students with specific knowledge were far more likely to adopt specific change actions than those who had less precise knowledge. They, in turn, were more likely to identify generic and less effective actions. The study concludes that the main challenge involved in changing tourism behaviour rests primarily with raising its status to a higher priority, a difficult task given the environmental issue overload that most people face.
