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.     

Vocational Experiences and Quality of Life of Migrants: Overview and Future Research

Quality of life is a complicated concept that has attracted broad attention from multiple disciplines. This article introduces a set of studies that employ diverse approaches to explore how work, vocational, and career experiences shape quality of life among migrants, and proposes a future agenda to extend this stream of research. Specifically, operationalizing quality of life in different ways, research showcased in this special issue has demonstrated how international and intranational migrants achieve, maintain, and enhance their well-being in different life domains. Reflecting on the literature and the showcased studies, this article proposes that future research should advance the current inquiry by better categorizing vocational experiences, uniquely operationalizing of quality of life in migration contexts, taking a more culturally sensitive perspective, and broadening methodological approaches.     

流动的困惑:跨国流动中的朝鲜族身份认同多元化

朝鲜族跨国人口流动及其规模在改革开放后的30多年中持续增长.在跌宕起伏、曲折多变的跨国流动中,在韩朝鲜族在不断改变其流动方式和生活环境的同时,实际也在改变着自己的社会关系和群体的归属结构,其归属感、价值观、认同感也在不断被打破和重塑.比起20世纪90年代末朝鲜民族“族性”的淡化与中国人的“国民性”的强化,21世纪前10年的后半期开始,由于韩国对朝鲜族政策环境的不断改善及朝鲜族本身的各种共时性的复杂身份,形成民族认同和国家认同的交错和张力,其身份认同呈现出日趋开放和多元的特点,这在某种程度上对国家认同的建构形成一定的冲击和挑战.     

民族文学国际传播中的文化传递——以《尘埃落定》英译本为例

中国民族文学作品的国际传播必须注意文化的传递,这对于塑造中华民族形象、突破他人话语体系、提升文化影响力具有重要意义。但由于文化空缺的存在,中国民族文化向外译介面临诸多难点。葛浩文夫妇翻译的阿来小说《尘埃落定》是将民族文化向国际传播的优秀成果,分析其在民族文化传递方面的得失和方法对于提高我国民族文学翻译质量和传播民族文化具有重要的借鉴意义。通过英汉文本比较发现,葛氏夫妇的译本综合采用了音译、直译、意译、形象借用等多种翻译手法,尽量保留了原作的文化意境,但也存在误译现象,扭曲或丢失了一些文化意象。总的来说,译本忠实地再现了川西高原土司制度瓦解时期的社会文化韵味,有效地传递了中国民族文化。     

Total completion time minimization in online hierarchical scheduling of unit-size jobs

This paper investigates an online hierarchical scheduling problem on m parallel identical machines. Our goal is to minimize the total completion time of all jobs. Each job has a unit processing time and a hierarchy. The job with a lower hierarchy can only be processed on the first machine and the job with a higher hierarchy can be processed on any one of m machines. We first show that the lower bound of this problem is at least \(1+\min \{\frac{1}{m}, \max \{\frac{2}{\lceil x\rceil +\frac{x}{\lceil x\rceil }+3}, \frac{2}{\lfloor x\rfloor +\frac{x}{\lfloor x\rfloor }+3}\}\), where \(x=\sqrt{2m+4}\). We then present a greedy algorithm with tight competitive ratio of \(1+\frac{2(m-1)}{m(\sqrt{4m-3}+1)}\). The competitive ratio is obtained in a way of analyzing the structure of the instance in the worst case, which is different from the most common method of competitive analysis. In particular, when \(m=2\), we propose an optimal online algorithm with competitive ratio of \(16\) \(/\) \(13\), which complements the previous result which provided an asymptotically optimal algorithm with competitive ratio of 1.1573 for the case where the number of jobs n is infinite, i.e., \(n\rightarrow \infty \).

民族概念三题

本文通过对汉语民族概念的模糊性,斯大林所论述的民族概念的外延与内涵,以及民族概念的政治属性等三个问题展开讨论,认为:第一,汉语民族概念实际表述着中华民族和构成中华民族的56个民族两个层次人们共同体的含义;第二,斯大林所定义的民族(нация)概念指的是汉语民族概念的第一层次,即中华民族这一层次的人们共同体;第三,不论是中华民族层次还是构成中华民族的56个民族层次的人们共同体都具有政治性,但是,两者的政治属性具有层次性,即前者的政治性与国家相关,而后者的政治性则与地方自治相联系。
