Aversive Peer Experiences on Social Networking Sites: Development of the Social Networking‐Peer Experiences Questionnaire (SN‐PEQ)

Cyber victimization is an important research area, yet little is known about aversive peer experiences on social networking sites (SNSs), which are used extensively by youth and host complex social exchanges. Across samples of adolescents (n = 216) and young adults (n = 214), we developed the Social Networking‐Peer Experiences Questionnaire (SN‐PEQ) and examined its psychometric properties, distinctiveness from traditional peer victimization measures, and associations with internalized distress. The SN‐PEQ demonstrated strong factorial invariance and a single‐factor structure that was distinct from other forms of peer victimization. Negative SNS experiences were associated with youths' symptoms of social anxiety and depression, even when controlling for traditional peer victimization. Findings highlight the importance of examining the effects of aversive peer experiences that occur via social media.     

人口老龄化与养老保障政策应对研究——基于多元社会政策建构视野

人口老龄化趋势是我国人口结构转变的一个突出现象。人口老龄化问题的突现,势必对养老保障压力提出了新的挑战,同时也会影响国家对养老政策的调整。本文基于＂人口年龄结构—国民经济因素—社会因素—养老政策＂综合分析模型,提出了养老保障政策分析的框架。本文以人口结构转变为切入点,描述了人口老龄化趋势,以及由此引发的国家系统养老保障以及公民社会养老保障挑战。为应对这些挑战,本文基于综合分析模型和现代国家治理结构特点,提出了相应的应对策略。本文认为,只有整体性福利制度构建,才能确保在国民经济发展、人口老龄化趋势与社会稳定之间取得动态平衡。     

Simulation analysis of cold chain performance based on time–temperature data

Perishable goods are a fundamental source of revenue for the retail sector; their management, however, constitutes a severe challenge for retailers and supply chain partners. A significant cost in particular is the fraction of products perished through the supply chain, which also constitutes an ethical and environmental concern. Supply chain organisation and operative characteristics have a significant influence on this matter, as in fact ensuring suitable temperature conditions for the stock-keeping units throughout the supply chain is mandatory for perishable products. Recent developments in sensing and communication technologies allow detailed monitoring and control of cold chain; however, depending on the characteristics of the supply chain, an inherent risk of perished products is often inevitable, even in the hypothesis of perfect control. This article proposes a methodology to evaluate the performance of a cold chain in terms of expected product quality at the retail store, and to estimate the expected fraction of perished products, according to the supply chain configuration. The approach is based on Monte Carlo simulation, and implements referenced shelf-life models. A real application is also presented, involving a preliminary analysis and mapping of the supply chain activities based on time–temperature data, in order to demonstrate the practicability of the approach proposed.     

在我国有步骤地实施物业税的构想

何谓物业税？“物业”一词，起源于我国香港,意指房地产。物业税,一般又称“财产税”或“地产税”，主要针对土地、房屋等不动产，要求其所有者或承租人每年缴付一定税款，税额随房产的升值而提高。在向地产或房产的占用者征收税款时,是按照市值比例“从价计征”。     

City Magazines

Abstract

This study compared two lists of full-text content available in Academic Search Elite. EBSCO provided the lists to the University College of the Fraser Valley. In this study, focus was placed on the accuracy of the claims of full-text content, because the staff and library users at University College of the Fraser Valley (UCFV, British Columbia) depend on this database as part of the libraries' journal collection. Interlibrary loan staff routinely used a printed list of Academic Search Elite to check whether the journal was available at UCFV in electronic form; therefore, an accurate supplemental list or lists of the library's electronic journals was essential for cost-conscious interlibrary loan staff. The results of the study were that there were inaccuracies in the coverage of fifty-seven percent of the journals sampled. Serials Review 2003; 29:11–15.

论英语文学研究的拓展

研究外国文学从很大程度上说是一种跨文化的文学阅读活动,20世纪的文学理论告诉我们,跨文化的文学阅读不可避免地会涉及到一个阅读者在阅读过程中择取什么样的阅读视角的问题.后殖民主义理论特别指出,当一个弱势文化在阅读一个强势文化的文学时,阅读视角的问题经常会表现得更加突出.我国对英语文学研究的历史和现状明确地反映出我国外国文学界的研究立场问题,由于长期以来存在一种自动认同西方大国的倾向,我国的英语文学研究常常将英语文学与英美两国文学等同起来.而要拓展我国的英语文学研究,必须首先调整我们的阅读视角和研究立场,在摆脱殖民心态的前提下坦然面对英美以外的一切后殖民英语文学.     

基于建设主体视角的羌寨重建路径研究

汶川地震后,各种力量介入羌寨重建工作,地方政府、援建方和当地民众是最主要的重建主体。根据不同重建主体在具体的村寨重建中发挥的作用不同,羌寨重建大体可分为统规自建、统规统建、统分结合三种重建路径,不同重建路径对当地羌族文化造成的影响也不尽相同。本文对这三种路径及其文化影响进行了调研分析,希望能为我国其他民族村寨建设提供参考。     

LGBTQI+ icons between resistance and normalization: looking for mediatization of emotions in hashtags

ABSTRACT

The mediatization of emotions emerges as an affordance of social media, the study of which involves paying attention to digital practices and to the construction and expression of public affection. This happens both for the great events and for the daily demonstrations of support or its denial. In this article we work on the phenomenon of the mediatization of emotions linked to two LGBTQI+ icons and expressed in hashtags on Twitter. Placing it in a specific context – the one of well-known television characters who have declared their homosexual orientation or transgender identity. The objective is to understand if the cloud of feelings they have created on Twitter is to be attributed to a true globally mediatized emotional exchange, or just an expression of emotions on the social media, and discover which emotional dynamics, linked to the LGBTQI+ world, they express.
