民工潮与城乡收入差距

农村劳动者到城镇打工,他们将自己获得的收入寄回家乡,提高了当地农村居民的家庭收入,但这并没有缩小城乡收入差距,相反我国城乡收入分配差距呈逐渐拉大之势。这里有复杂的原因。从目前来看,我国农村劳动力流向城镇对缩小城乡收入差距没有多大帮助,要有效缩小我国城乡收入差距还应结合消除不合理的行业进入壁垒,发展农村经济等措施。     

城乡发展差距的人力资本解释

人力资本在城市和农村具有不同的溢出效应,农村人力资本具有强烈的外溢性特征,而城市人力资本则具有强烈的内溢性特征。长期以来,农村人力资本对城市经济发展形成了强有力的支持,而城市人力资本则形不成对农村的支持。建国以来城乡之间在人力资本投入及形成后的人力资本作用的发挥上,都存在着城市对农村的“剥夺”,而且这种剥夺远远超过了人们常常提到的以往和正在进行的对农民利益的三次“剥夺”。我们认为,政府在着手解决农村、农业和农民问题时,应该从根本上即从人力资本投资及完善农村人力资本运行环境上入手,使农村人力资本能够对农村经济发展发挥很好的作用,并在一定程度上吸引城市人力资本,只有这样才能真正缩小城乡收入差距。     

The gender gap in pro-environmental political participation among older adults

Citizens are increasingly concerned with environmental issues and some of them take contentious political actions or adapt their lifestyles to reduce their environmental footprint. Research finds that there is an eco-gender gap in everyday environmental behaviours, with women more active than men. However, studies of the eco-gender gap have infrequently looked at other forms of pro-environmental political behaviours and focused mostly on young people. We contribute to the literature by examining to what extent older women and men differ in a range of pro-environmental political behaviours, using a unique dataset based on a survey of individuals 64 years and older. We find strong evidence of a gender gap in everyday behaviours and political consumerism, but not in relation to contentious forms of political participation. This gender gap in relation to everyday behaviours and political consumerism diminishes with age.     

Italian Migration Policies in Times of Crisis: The Policy Gap Reconsidered

Abstract

Numerous studies have shown that there is a structural gap between restrictive migration policies and expansive inflows in democratic countries; yet scholars have not sufficiently reflected on how this gap is shaped in times of crisis. Focusing on the case of Italy in the decade between 2007 and 2017, this article assesses the extent to which the different challenges triggered by the economic and humanitarian crises have affected the structural gap, and which actors have mostly contributed to shape it. Our analysis of the Italian case shows how in the decade of the economic crisis the migration policy gap has not been the result of pressure by actors in the economic and liberal norm spheres, but rather reflects conflictual relationships within the political-institutional sphere between Italian governments and EU institutions.     

Translating Policies into Informal Settlements' Critical Services: Reframing,Anchoring and Muddling Through

This paper examines how policies and plans are translated into informal settlements' practice. It builds on literature on policy implementation practice and organization studies, and more particularly, it applies the concepts of reframing, anchoring and muddling through. The paper is informed by the case of Kisumu City in Kenya and its Kisumu Integrated Solid Waste Management Plan and its implementation on Kisumu's informal settlements. The plan was funded by the Swedish International Development Agency through the United Nations Human Settlement Programme and implemented from 2007 to 2009. The study is based on action research carried out by a multidisciplinary and transdisciplinary group of researchers, through focus groups, participatory workshops, collaborative action, in‐depth interviews, document analysis and observations. The paper examines what original aspects of Kisumu Integrated Solid Waste Management Plan were translated, that is, which ones faded out and which ones became stabilized into and travel as ‘best practices’ to other locations. The paper shows how the generation of ‘best practices’ can be loosely coupled with the practices that policy seeks to change. It concludes, in line with previous research in the field, how successful policy implementation is based on cultural and political interpretations rather on evidence of improved practices.

Winners,Losers, and the Press: The Relationship Between Political Parallelism and the Legitimacy Gap

Recent work has explored how individual and institutional factors affect the gap in perceptions of political legitimacy between electoral winners and electoral losers, but has ignored the role that the political information environment, in general, and ideologically biased media, in particular, plays in exacerbating or diminishing this gap. By combining individual-level public opinion data in 28 countries, an expert survey on media systems, and a variety of country-level indicators, I find that higher levels of political parallelism in a country are associated with a larger winner-loser gap in institutional trust and satisfaction with democracy. The relationship is contingent on whether or not people are actually exposed to said media. This research, which links the study of political communication with the study of comparative political behavior, indicates that the increasing availability of partisan news around the world is a cause for concern.     

Social Inequality and the Perceived Income Justice Gap

This paper attempts to answer the question whether justice evaluations of income inequality in a society are determined more by country differences or by the social position an observer occupies. In very general terms what we study is whether, in shaping justice beliefs, cultural factors are more important than social-structural ones, or vice versa. In view of transformation societies, country differences are conflated with differences in the transformation processes the countries are experiencing. This is why we distinguish different types of transmations with regard to the postcommunist countries of Eastern and Central Europe testing empirically whether these transformation types exert influence on the justice beliefs, and how this influence compares to that of positional effects. With International Social Justice Project (ISJP) data of 1991 and 1996, we study the Czech Republic, Hungary, Russia, Bulgaria, East Germany, and—as a western referent society—West Germany. Main results are that in the early phase of transformation the different transformation types as well as social positions matter in shaping justice evaluations, over time, however, the types of transformation clearly lose influence. In 1996, compared to 5 years earlier, the countries have become similar in that most of the variation in the perception of the income justice must now be attributed to the positional differences of individuals. We conclude that the characteristics of the transformation processes decrease in importance for determining public views about social justice. In this respect, the transformation societies of Eastern and Central Europe may well be on the route to becoming more like western societies.     

“80后”的多维解读

“80后”这一概念反映了社会快速发展过程中代际之间的文化断裂和价值冲突。“80后”的成长经历、家庭环境和社会环境都不同以往,他们是特殊环境中成长起来的一代。“80后”现象折射出的是当今的时代问题,这些问题反映在社会生活的方方面面,整个社会都需要对此进行反思。从历史发展来看,年青一代的观念不同于传统,这是世界各国发展中的正常现象。我们应当以平常心看待“80后”,对他们充满信心,陪伴他们一起成长。     

Leveraging virtual machine introspection with memory forensics to detect and characterize unknown malware using machine learning techniques at hypervisor

The Virtual Machine Introspection (VMI) has emerged as a fine-grained, out-of-VM security solution that detects malware by introspecting and reconstructing the volatile memory state of the live guest Operating System (OS). Specifically, it functions by the Virtual Machine Monitor (VMM), or hypervisor. The reconstructed semantic details obtained by the VMI are available in a combination of benign and malicious states at the hypervisor. In order to distinguish between these two states, the existing out-of-VM security solutions require extensive manual analysis. In this paper, we propose an advanced VMM-based, guest-assisted Automated Internal-and-External (A-IntExt) introspection system by leveraging VMI, Memory Forensics Analysis (MFA), and machine learning techniques at the hypervisor. Further, we use the VMI-based technique to introspect digital artifacts of the live guest OS to obtain a semantic view of the processes details. We implemented an Intelligent Cross View Analyzer (ICVA) and implanted it into our proposed A-IntExt system, which examines the data supplied by the VMI to detect hidden, dead, and dubious processes, while also predicting early symptoms of malware execution on the introspected guest OS in a timely manner. Machine learning techniques are used to analyze the executables that are mined and extracted using MFA-based techniques and ascertain the malicious executables. The practicality of the A-IntExt system is evaluated by executing large real-world malware and benign executables onto the live guest OSs. The evaluation results achieved 99.55% accuracy and 0.004 False Positive Rate (FPR) on the 10-fold cross-validation to detect unknown malware on the generated dataset. Additionally, the proposed system was validated against other benchmarked malware datasets and the A-IntExt system outperforms the detection of real-world malware at the VMM with performance exceeding 6.3%.     

Electoral outcomes and satisfaction with democracy: A comparison of regional and national elections

Subnational governments have become more numerous and more powerful around the world, increasing the importance of subnational elections. However, we still know little about the impact of regional electoral outcomes on citizens' political support, and there is no systematic comparison of the impact of election outcomes on citizens' satisfaction with democracy. In this research note, we provide such a comparison by investigating how the winner-loser gap in citizens’ satisfaction with democracy differs across regional and national elections. Using data from Canada, Germany and Spain, we first show that there is a winner-loser gap in satisfaction with democracy following regional elections. The winner-loser gap at the regional level is, however, substantially smaller than the one generated by national election outcomes. Next, we find heterogeneous effects for voters who believe that the regional government strongly influences their quality of life. We conclude by discussing the implications of our findings.
