为什么历史上经营式农业不发展：以无锡为案例

本文基于第一、二次对"无锡、保定农村调查"的资料,分析说明了无锡农村经营式农业的日渐式微,并从出租农地与雇工经营的收益方程、较高工商业发展水平导致的机会成本增加,以及家庭小农场的竞争三个方面分析了经营式农业不发展的原因.我们认为,主要是当地较高但又不足够高的工商业发展水平导致了经营式农业难以发展.较高的工商业发展水平意味着发展经营式农业的高运营成本和高机会成本.不足够高又使得非农产业的需求与人数众多的农业过剩劳动力不相匹配,从而造成了家庭小农场和经营式农场之间的激烈对抗.我们也认为,中国未来的农业农村现代化道路可能会依然呈现出复杂性和特殊性,家庭小农场扮演的角色可能仍然不容忽视.     

新乡贤重塑乡规民约:历史承继、时代价值及实现路径

当前乡村治理中乡规民约面临德治退化、自治弱化及法治虚化等现实困境。新乡贤作为乡村社会精英群体,在增强乡规民约的现代性、厚植乡规民约的乡土性及强化乡规民约的权威性等方面具有显著的时代价值,是重塑乡规民约的有益主体选择。实现新乡贤在重塑乡规民约中的时代价值,需要强化乡贤文化的敦风化俗功能、构建乡贤群体的风险防范机制及发挥乡贤组织的协商共治作用。     

Rural-urban differences in college students’ cardiovascular risk perceptions

Abstract

Objective: To examine rural-urban differences in college students’ cardiovascular risk perceptions. Participants: College students in rural (n?=?61) and urban (n?=?57) Kentucky counties were recruited from November 2012 to May 2014. Methods: This was a secondary data analysis of a cross-sectional study examining rural-urban differences in cardiovascular risk factors. Students rated their risk for developing high blood pressure, diabetes, high cholesterol, heart disease, having a stroke, and gaining excess weight. Chi-square and logistic regression were used for data analysis. Results: Rural students had lower odds of perceived high risk for developing high blood pressure compared to urban students (odds ratio (OR): 0.32, 95% CI: 0.11–0.96) after adjusting for race, sex, and body mass index. This association was not observed after adjusting for healthcare access variables. No other significant differences were observed. Conclusions: Efforts to raise perceived risk for developing hypertension among rural college students may be warranted.     

挣脱生态牢笼的路径探幽——《共产党宣言》中马克思生态思想解读

《共产党宣言》蕴含着深刻的生态思想,其体系以人、社会、自然整体为背景,其核心观点认为生态问题是由资本主义生产方式引起的.马克思在唯物史观视野下,科学论证了资产阶级的所有制必然灭亡、共产主义必然实现的历史发展逻辑,廓清了人与人、人与自然之间双重和解的演化路径.其中关于科技提升、市场拓展、交通和通信发展等引起世界市场“生态扩张”的思想,对全球化程度日益加深境况下“生态文明”和“人类命运共同体”的构建具有重大的理论和实践指导价值.     

My life is a mess: self-deprecating relatability and collective identities in the memification of student issues

ABSTRACT

In this paper, we investigate memes about student issues. We consider the memes as expressions of a new networked student public that contain discourses that may fall outside the mainstream discourse on higher education. The paper is based on content analysis of 179 posts in the public Facebook Group ‘Student Problem Memes’, combined with a nine-month media watch and a discussion workshop with 15 students. Through self-deprecating humour, students create an inverse attention economy of competitive one-downmanship, where the goal is to display humorous failure instead of perfect appearance. Our analysis shows that students use humour to express, share, and commiserate over daily struggles, but also that the problems related to work/study balance and mental health, are experienced as a persistent feature of student living. We also analyse limitations of meme-based publics, emphasizing processes of inclusion and exclusion through specific vernaculars of visual and discursive humour where issues related to gender, race, orientation, class, and ability are sidelined in favour of relatable humour.     

The politics of the Digital Single Market: culture vs. competition vs. copyright

This paper examines the implications for European music culture of the European Union’s (EU) Digital Single Market strategy. It focuses on the regulatory framework being created for the management of copyright policy, and in particular the role played by collective management organisations (CMOs or collecting societies). One of the many new opportunities created by digitalisation has been the music streaming services. These depend on consumers being able to access music wherever they are, but such a system runs counter to the management of rights on a national basis and through collecting organisations which act as monopolies within their own territories. The result has been ‘geo-blocking’. The EU has attempted to resolve this problem in a variety of ways, most recently in a Directive designed to reform the CMOs. In this paper, we document these various efforts, showing them to be motivated by a deep-seated and persisting belief in the capacity of ‘competition’ to resolve problems that, we argue, actually lie elsewhere – in copyright policy itself. The result is that the EU’s intervention fails to address its core concern and threatens the diversity of European music culture by rewarding those who are already commercially successful.     

Violence in the name of god? A framing processes approach to the Islamic State in Iraq and Syria

Since summer 2014, the insurgent group ‘Islamic State in Iraq and Syria’ (ISIS) has become a major concern for international politics and global security due to its rapid territorial gains, violent operations and the propagation of Salafi-jihadist ideology. This study aims to enhance the academic understanding of ISIS by demystifying the ideological reasoning behind its use of violence. It therefore investigates the link between structural factors that served ISIS’s evolution, its ideological outlook and the significance of this ideology to legitimize violent action. As its theoretical basis, the study employs framing processes within the study of social movements. Methodologically, discursive frame analysis serves to explore the relation of ISIS’s ideology to structural events and experiences to better understand how the group justifies violence. Therefore, the study draws on audio speeches and issues of the magazines Dabiq and Dar al-Islam published by ISIS, which are examined on the rhetoric of othering, collective identity and justifying violence. It is argued that ISIS constructs a collective action frame which creates a social reality that bestows the group with a rationale for action. ISIS’s ideology, based on Islamic symbolism, presents an interpretative lens which assigns meaning to the structural environment of ISIS’s emergence. In this context, violence is justified as a necessity to defend Islam and as an obligation for the true Muslim believer. The discussion concludes that ISIS’s ideology legitimizes the very existence of the group and conceals its mundane struggle for power, territory and wealth through reference to divine authority.     

Better educational inclusion of migrant children in urban schools? Exploring the influences of the population control policy in large Chinese cities

The educational inclusion of rural–urban migrant children in Chinese urban schools has been promoted in the past decades. This paper provides a contextualized interpretation of recent policy developments governing large Chinese cities and evaluates its impact upon the status of migrant children's education. Drawing on data collected from 1,331 migrant children in urban inclusive schools, this study compared current migrant children's family backgrounds and psychological sense of belonging at school in relation to educational outcomes at the primary education level. Results showed that migrant children's socioeconomic status (SES) levels were slightly higher than their counterparts in inclusive schools and a salient SES stratification of migrant students was found. This correlates with students’ reports of fewer incidences of discrimination than hypothesized. Furthermore, capital in migrant families was positively associated with the psychological sense of belonging and academic achievement. These results reveal a significant change to migrant students’ SES as a result of the recent population control policy pertaining to China's large cities since 2014. Implications for research and educational practice, especially with at‐risk migrant students of low‐SES, are discussed.     

Social cohesion in Rwanda: Results from a public good experiment

We describe a public good experiment, a type of economic experiment commonly used to examine feelings of prosociality—that is, behaviour which is positive, helpful and intended to promote social acceptance and friendship—and community cohesion, carried out in Rwanda. Contributions in different parts of the country are affected by the local intensity of the 1994 genocide, with more generous contributions being made in areas where violence was greater. This supports earlier research indicating that conflict experience leads to greater prosociality. However, we also find that people who have not, themselves, been targets of violence give lower contributions than people who have. The considerable group‐related and regional differences in social behaviour may have implications for the country's policies to deal with social cohesion.     

Closure property of consistently varying random variables based on precise large deviation principles

Let X = {X₁, X₂, …} be a sequence of independent but not necessarily identically distributed random variables, and let η be a counting random variable independent of X. Consider randomly stopped sum S_η = ∑^η_{k = 1}X_k and random maximum S_(η) ? max?{S₀, …, S_η}. Assuming that each X_k belongs to the class of consistently varying distributions, on the basis of the well-known precise large deviation principles, we prove that the distributions of S_η and S_(η) belong to the same class under some mild conditions. Our approach is new and the obtained results are further studies of Kizinevi?, Sprindys, and ?iaulys (2016) and Andrulyt?, Manstavi?ius, and ?iaulys (2017).
