未观测经济：概念框架与测算思路

 经济合作与发展组织牵头编写的《未观测经济测算手册》对“未观测经济”的概念、分类原则、测算方法等做了较为详细的论述,本文根据其中的主要概念比较分析了官方公布的GDP与未观测经济之间的关系,目的是能在国际统计标准概念框架下更好地理解未观测经济、未测算经济、官方公布的GDP之间的关系与区别。     

浙江区域金融结构对产业集聚的影响研究 ——基于面板数据的实证分析

 以民营企业为基础的产业集聚群是浙江经济快速发展的重要原因。然而产业集聚的形成依赖于一定的外部环境,特别是对于资金的需求和金融结构有特殊的要求。本文通过对浙江11个市2000-2007年的面板数据,分析不同的金融结构对产业集聚的影响。并根据研究结论,提出了优化区域金融结构,促进浙江产业集聚群健康发展的对策建议。     

欧洲一体化进程中的宗教因素

随着欧洲一体化进程的不断扩大和深入,宗教多样化问题已成为影响其进程的一个十分重要的因素.具有基督教历史与文化传统的欧洲,在迈向一体化的过程中受到了异质文化伊斯兰教日益凸显的影响.如何适应宗教差异和减少宗教冲突,从而达成各种文化的和谐相处,已成为需认真讨论和解决的问题.     

中泰外商直接投资实证研究——以泰国金融结构金融效率为分析对象

在"一带一路"倡议的推动下,泰国作为东盟第三大经济体,以其优越的地理优势和战略地位吸引了不少中国投资者进入泰国投资,而其金融结构与金融效率对中国直接投资有着重大影响.文章通过对金融结构、金融效率及中国在泰国直接投资的分析发现,尽管泰国通货膨胀率、泰国工业生产指数对中国在泰国直接投资没有显著影响,但泰国居民消费指数、泰国商业银行存贷比率、泰国生产价格指数、泰国失业率对中国在泰国直接投资会产生负向影响,而中国与泰国之间的进出口额对中国在泰国直接投资可以产生正向影响.因此,鼓励中国投资者向泰国投资,加大两国贸易合作以及开展两国文化交流,是促进中国和泰国经济进一步发展的有效措施,也是实现互助互利,合作共赢的"一带一路"经济合作目标的有效方法.     

A balancing act in urban social-ecology: human appreciation,ponds and dragonflies

Green spaces in cities provide cultural ecosystems services (CES) such as nature connection, wildlife interaction and aesthetic appreciation which can improve aspects of human well-being. Recognising these benefits, researchers are now examining the complex relationship between humans and nature in urban social-ecology. Most studies investigate people’s appreciation and valuation of different green space features and their contribution to urban biodiversity. Recommendations arising from such studies are best practices to achieve a balance between landscape aesthetic and ecological objectives, but many knowledge gaps still exist. In a social-ecological project in Greater London, appreciation of ponds and dragonflies in urban green spaces, and the environmental factors determining dragonfly diversity were investigated. We found ponds and their appearance were valued by people as enhancing their green space experience. The preference for wild-looking ponds was moderate. Dragonflies were enjoyed for their colour and high visibility, especially by those who had basic dragonfly knowledge. Species richness of dragonflies was positively associated with habitat heterogeneity in and around a pond. However, people were unable to relate a heterogeneous pond to more dragonfly species. For the first time, some factors that influence the human appreciation-ponds-dragonflies (HPD) relationship in an urban context are revealed. To fully realise the CES potential of ponds and dragonflies in Greater London, a HPD framework is proposed. The framework underpins strategies that foster cultural sustainability for ponds and dragonfly conservation.     

The expected and unexpected media effects on youth’s (mis)perceptions of peer norms: Chinese college students’ overestimation of peer smoking prevalence

Youth’s perceptions of peer norms have profound effects on their attitudes and behaviors. Unfortunately, their perceptions of peers tend to be biased. To investigate the role of media in the formation of misperceived peer norms, the current study tested and compared two media-effect mechanisms: the direct exemplar mechanism and the indirect influence of presumed influence (IPI) mechanism. The two mechanisms were tested in a sample (n = 1746) that is representative of college students in one large university in China, based on which the actual and perceived campus smoking rates were examined. The individual-level perceived peer smoking prevalence was then analyzed in comparison with the campus-level actual smoking prevalence. The results revealed serious overestimations of peer smoking prevalence. As predicted, pro-smoking media content significantly heightened smoking prevalence estimates through both exemplar and IPI mechanisms. In contrast, anti-smoking messages did not elicit any intended effect through the IPI mechanism, but showed a boomerang effect through the exemplar mechanism. These findings suggest that both pro- and anti-smoking media content may be responsible for inflated perceptions of peer smoking among youth.     

Functional analysis of high-content high-throughput imaging data

High-content automated imaging platforms allow the multiplexing of several targets simultaneously to generate multi-parametric single-cell data sets over extended periods of time. Typically, standard simple measures such as mean value of all cells at every time point are calculated to summarize the temporal process, resulting in loss of time dynamics of the single cells. Multiple experiments are performed but observation time points are not necessarily identical, leading to difficulties when integrating summary measures from different experiments. We used functional data analysis to analyze continuous curve data, where the temporal process of a response variable for each single cell can be described using a smooth curve. This allows analyses to be performed on continuous functions, rather than on original discrete data points. Functional regression models were applied to determine common temporal characteristics of a set of single cell curves and random effects were employed in the models to explain variation between experiments. The aim of the multiplexing approach is to simultaneously analyze the effect of a large number of compounds in comparison to control to discriminate between their mode of action. Functional principal component analysis based on T-statistic curves for pairwise comparison to control was used to study time-dependent compound effects.     

FTF与CMC沟通形态与冲突强度、沟通满意度的关系研究

本文以新媒体沟通在企业内部主导地位的逐步形成为背景,对新媒体沟通形态与团队冲突强度、沟通满意度的关系进行研究。研究结论表明:沟通形态对于智力型任务中的团队冲突有显著影响,CMC沟通形态的团队冲突显著高于FTF;而沟通形态对于团队沟通满意度也有影响,CMC沟通形态的沟通满意度显著低于FTF,其中CMC沟通形态的媒体满意度显著低于FTF,而对于过程满意度两种沟通形态并无差异;团队冲突强度与媒体满意度呈负相关,冲突强度与过程满意度以及沟通满意度无显著关系。
