一种组合式衰减地震资料中多次波的方法

在海上地震勘探中我们最常见的干扰波就是多次波。多次波的存在,严重地干扰了地震记录,妨碍我们对有效波的辨认。在剖面上存在较强的多次波时,如果在解释中不能正确地把多次波识别出来,就会造成错误的地质解释。所以,在海洋地震资料的处理中,多次波的衰减是极为重要的一个环节,对于中、深层海洋地震资料,本文采用如下方法压制多次波,先进行SRME方法去除长周期多次波能量,再应用tau-p域内预测反褶积去除占大部分的短周期多次波,最后用高精度Rado变换去除剩余的多次波,实际资料结果表明,该方法有不错的效果。     

Space and Identity in Resistance against Neoliberal Urban Planning in Turkey

This article highlights the role of collective identity and space in the emergence of social resistance within a neoliberal context. It argues that the attempted eviction of residents from their established neighbourhoods through public planning projects generates resistance against the reappropriation of these spaces and has encouraged new forms of resistance among inhabitants in several neighbourhoods. I particularly emphasize that planning projects often displace particular populations by force, principally minority communities, in order to confine them to new resettlement areas far from their customary living places, which has a socioeconomic impact on people's identity, everyday life and social solidarity. The article is based on empirical research in two neighbourhoods in Istanbul — 1 May?s and Sulukule — to analyse practices of resistance of inhabitants in everyday life and examine how this resistance shapes their identity and daily life.

Spatio-temporal determinants of the structural and productive transformation of regions in Central and East European countries

This paper investigates the determinants of the structural (between-sectoral) and productive (within-sectoral) transformation of 56 NUTS2 regions in Central and East European (CEE) countries over the 2008–2014 period. Over the analysed period, a transformation of the analysed regions has taken place towards the tertiary sector and high value-added activities. The results from a spatial panel Durbin analysis reveal the existence of product-space linkages and point to a productive transformation towards high technology-intensive activities as an important driver of industrial development. Equal access to digital infrastructure in urban and rural areas and transfer of skills, knowledge and resources through the inflow of foreign investment and imports of production inputs increase the contribution of manufacturing to regional employment. The effect of profit tax reductions on the share of manufacturing employment is about five times larger than the effect of government subsidies to production.     

EXPLAINING DIFFERENCES IN EFFICIENCY: A META‐STUDY ON LOCAL GOVERNMENT LITERATURE

This paper reviews the literature on local government efficiency by meta‐reviewing 360 observations retrieved from 54 papers published from 1993 to 2016. The meta‐regression is based on a random‐effects model estimated with the two‐step random‐effects maximum likelihood (REML) technique proposed by Gallet and Doucouliagos. Results indicate that the study design matters when estimating a frontier in local government. We find that studies focusing on technical efficiency provide higher efficiency scores than works evaluating cost efficiency. The same applies when using panel data instead of cross‐section data. Interestingly, studies that use the Free Disposal Hull (FDH) approach yield, on average, higher efficiency scores than papers employing the data envelopment analysis (DEA) method, thereby suggesting that in this literature the convexity hypothesis of the production set is a matter. Finally, the efficiency of local government increases with the level of development of the analysed countries and is positively related to the national integrity of the legal system. The opposite holds when considering the corruption.     

智慧社区目标导向下老旧社区适老化改造研究

随着时代的发展,我国人口老龄化现象日益严重,许多城镇社区组织建设过程中,发现了较具代表性的老龄化社区。这些老龄化社区除了居住人口为老年人之外,社区本身的基础设施建设也十分陈旧。倘若不对这类社区进行适老化改造,那么居住其中的老年人就无法拥有高质量生活体验。进入智能时代后,智能化社区建设也开始逐步兴起,对于行动受限的老年人而言,对其居住的老旧社区进行智能化改造是很有必要的。论文对此进行研究与分析。

The growth paradox,sustainable development,and business strategy

Economic growth is a two-edged sword. Expanding economies and industries create wealth and employment, but global economic expansion is having unprecedented deleterious impacts on vital planetary systems. Despite this, the core strategic goal of all economies and many businesses continues to be the pursuit of ongoing economic growth. To resolve this paradox, a reconceptualization of firm-level growth is presented. I describe and discuss the organizational characteristics of the growth paradox and follow this with a metatheoretical review of economic, organizational, and ecological perspectives on growth. From this review, a typology of firm-level strategy is developed that radically reconceptualizes business growth as developmental activity primarily concerned with social–ecological flourishing. The features of this typology and its implications for business strategy are discussed according to three principles that emerged from the analysis: multidexterity, resilience thinking for design, and inclusive balance (embeddedness). Together, these strategy principles form the prerequisite management competencies needed for the development, implementation, and evaluation of sustainable business strategies. Transformative firm-level responses to the growth paradox are needed if sustaining forms of organizational growth are to be achieved and this paper presents a novel integrative framework for informing those strategies.     

DEA方法在供应链绩效评价中的应用
