感知风险对在线旅游产品购买意愿的影响分析

旅游电子商务发展迅猛,互联网购物平台的虚拟性和远程性强化了消费者感知风险,它也成为影响旅游电子商务发展的重要因素之一.文章聚焦消费者感知风险,运用SPSS 19.0及AMOS 21.0软件,构建以5个维度的感知风险为自变量、购买意愿为因变量、信任为调节变量的结构方程模型,探讨变量间相关关系.结果发现:感知风险对信任的影响差异较大,仅经济风险感知与信任呈显著负相关;感知风险对购买意愿总效应皆呈负相关;信任作为中介变量存在明显的调节作用,有效地降低了感知风险对购买意愿的负向影响.     

Humor and satire in politics: Introducing cultural sociology to the field

The landscape of political humor and satire is changing rapidly, and it is becoming an increasingly relevant aspect of our culture. Although scholars have been actively trying to capture this change, majority of the existing frameworks for understanding humor and satire in politics still reduce these phenomena to mere genres or rhetoric tools. In addition, they provide insufficient accounts concerning the reception of humor and satire, and neglect to interpret and explain what they communicate. In the article, a general understanding of humor and satire outside of a political context, followed by an overview of studies discussing humor and satire in politics through their applications in social movements, as leadership tools, and through their manifestations in mass media has been presented. Lastly, a cultural sociological perspective to the field has been introduced. It has been argued that approaching humor and satire in politics through a structural hermeneutic method of the Strong Program will enable us to recognize and treat political humor and satire as autonomous and complex cultural systems which carry an internal power to move people.     

Informality,emotion and gendered career paths: The hidden toll of maternity leave on female academics and researchers

While the negative impact of child‐raising and caring on women's career progression in academia is well‐established, less is known about the role of academic women's lived experiences of maternity leave as an institutional practice. This article presents the findings of a qualitative study of the lived experiences of female academics and researchers in an Irish university. The analysis intrinsically links organizational structures and problems with the lived and felt dimensions of work. The findings point to the need for better structural accommodations for maternity leave which address the relationship between caring and career disadvantage within academia. The article adds to existing literature on the intersection of motherhood and academia by unpicking the specific role of maternity leave as both a lived experience and an institutional practice that can reinforce gender inequalities in academia.     

State‐led industrial development,structural transformation and elite‐led plunder: Angola (2002–2013) as a developmental state

From 2002 to 2013, Angola engaged in large‐scale state‐led reconstruction and development alongside an elite‐led appropriation and seizure of national assets. Until the oil price shock, Angola had been succeeding in promoting rapid economic growth, and possibly even significant social development, alongside a massive grab of wealth and power by local elites. Today, though an economic crisis has taken hold, frequent predictions of the country's imminent collapse have yet to be fulfilled. This article reviews the state's development planning and expenditure with a focus on public investment and industrial development to determine to what extent Angola during this period might be considered a developmental or petro‐developmental state. It is argued that, while more significant than generally thought, petro‐developmental outcomes were and are limited by the autocratic and neopatrimonial tendencies of the Angolan elite. Nevertheless, limited success with structural transformation may have lasting effects. Following its long civil war, the conditions existed for Angola to follow a new path of state‐led development. Though it may now be more difficult, structural transformation and economic diversification remain the only path to economic and social development.     

Generic Processes in Aligning the Multiple Bases of Identity: The Case of Becoming a Ministry Student

Identity theory distinguishes three bases of identity—role, group, and person—but studies have typically focused on one identity at a time. The interrelationship among the multiple bases of identity remains understudied. This study examines the multiple bases of identity individuals engage on their way to becoming ministry students. The results reveal the advantage of examining the multiple bases of identity as subcultural processes, the utility of qualitative research for expanding the empirical scope of identity theory, and the possibility of employing structural symbolic interactionist concepts within a processual symbolic interactionist agenda.     

Risk-Informed Requirements for Design and Assessment of Structures Under Temporary Use

The relatively high failure rates, with important consequences in many cases, suggest that the implicitly acceptable risk levels corresponding to temporary civil engineering structures and activities might exceed the bounds of normally acceptable levels associated with different societal activities. Among other reasons, this may be attributed to the lack of a rational approach for the assessment of risks associated with the different technologies supporting these activities in general, and for structures in particular. There is a need for establishing appropriate target reliability levels for structures under temporary use taking into account specific circumstances such as reduced risk exposure times. This issue is being addressed in this article. Acceptance criteria for building-structure-related risks to persons obtained in prior studies are adapted to the special circumstances of nonpermanent risk exposure. Thereby, the general principle followed is to maintain the same risk levels per time unit as for permanently occupied buildings. The adaptation is based on the statistical annual fatality rate, a life safety risk metric that allows for a consistent comparison of risks across different societal activities and technologies. It is shown that the target reliability indices taking account of the temporary use of buildings might be significantly higher than the values suggested for permanently used structures.     

对海洋霸权与大陆均势关系的再探讨

虽然以往研究海洋霸权与大陆均势关系的成果颇丰,但还是存在一些不足。为此,本文对海洋霸权与大陆均势关系的结构类型、运行机制及其影响等进行了深化与细化。在海洋霸权国国力大于或小于或等于大陆均势中的有关国家的不同情况下,大陆均势可以分为不需要海洋霸权仅凭大陆国家就能形成的大陆均势和需要海洋霸权且支持其中一方才能形成的大陆均势。不同的国力对比和均势构成情况,对海洋霸权与大陆国家的政治安全与经济发展所产生的影响是不同的。经过分析和比较,本文得出结论:海陆分界难分优劣,关系互补战略呼应,这就是美英极力推行海洋霸权与大陆均势战略的现实诠释。

Structural change in Ethiopia

This article investigates the pace and pattern of structural change in Ethiopia. It departs from the existing literature in two main ways. First, it uses a methodology that enables a more comprehensive assessment of structural change. Second, it entailed the construction of a consistent dataset for Ethiopia—comprising three labour force surveys—tracking 10 economic sectors between 1999 and 2013. Our analysis suggests that the structure of production has changed considerably, but that shifts in the composition of employment have lagged behind. Output per capita growth has been strong and mainly driven by within‐sector productivity improvements. However, the contribution of structural change has increased over time, which is encouraging. Evidence of a growing demographic dividend is also uncovered.     

河北省职业教育发展与产业结构关系的实证研究

职业教育与区域产业之间存在着相互影响的关系。基于河北省2000—2017年的时间序列数据,利用Eviews8.0软件分析工具,运用格兰杰因果关系检验方法对河北省职业教育发展规模与其三大产业发展水平之间的关系进行了检验。其结果表明:河北省职业教育发展规模影响第二产业发展水平;河北省职业教育对产业结构优化升级贡献不足;河北省职业教育与三大产业发展之间尚未形成良性互动机制。因此,必须进行职业教育供给侧结构性改革,构建河北省职业教育与区域经济协调发展机制:一是加强顶层设计,完善职业教育与区域经济产业协调发展的体制机制;二要优化专业结构,适应并引领河北省经济产业发展;三要深化内涵发展,提高职业教育人才培养质量。
