牛支原体诱导宿主免疫应答的研究进展

牛支原体(Mycoplasma bovis)是一种重要的兽医病原体,牛支原体感染给当前世界养牛业造成了重大的经济损失。本文从天然免疫、体液免疫和细胞免疫三个方面,对宿主感染牛支原体后的免疫应答特点进行了概括和讨论,可帮助我们更好地了解牛支原体与宿主的相互作用,也为合理地设计和研发有效的牛支原体感染防控技术提供参考。     

The treatment ideal and detention reality: Demographic,professional/ occupational and organizational influences on detention worker punitiveness

For some time, corrections researchers have focused on the punitive and rehabilitative orientations of correctional officers. Relatively little research attention, however, has been devoted to understanding the support for these orientations among correctional workers responsible for the care and custody of juvenile delinquents. Based on survey data drawn from a sample of detention care workers (DCWs) in two facilities in a Southeastern state (N=109), this paper examines the extent to which, and why, DCWs adopt a punitive orientation to youth in detention despite policies and training that discourage this view. Findings, that contrast the relative impact of demographic, occupational/professional and organizational environment variables in accounting for variation in punishment/control orientation among DCWs, suggest that demographic indicators (i.e., age, gender) and organizational environment contribute disproportionately to explained variance in punitive orientation once other variables are controlled. Implications for detention policy, staff recruitment and training are discussed.

Consumer well‐being through engagement and innovation in higher education: A conceptual model and research propositions

With globalization and the marketization of higher education, the relationship between higher education institutions (HEIs) and students is becoming more complex. As the cost of higher education increases, the expectations of students have not only changed dramatically but, combined with heightened competition in the market, it is clear that the balance of power has moved towards the students. Operating across this new landscape, HEIs are facing a different set of opportunities and challenges. In order to survive, differentiation through service innovation is imperative to achieving success in attracting and retaining students. While this has been voiced by a number of authors, until now, there is a paucity of empirical research examining the impact of service innovation in higher education on individual customer outcomes. This paper explores the links between service innovation and well‐being and the mediating roles of perceived service quality and customer engagement within the higher education context. The research is timely as previous studies have not taken into consideration the mediating roles of customer engagement between service innovation and customer well‐being. Yet, unless customers are engaged and participating in the service innovation process, or satisfied with the service innovation, the innovation may not lead to the desired customer outcomes. HEIs cannot afford to ignore the expectations of their primary customers (students). Hence, this conceptual paper seeks to develop a conceptual model of how service innovation leads to student/consumer well‐being and the mechanism through which perceived service quality and customer engagements affects this process.

Yarmouk,Jordan, and Disi basins: Examining the impact of the discourse of water scarcity in Jordan on transboundary water governance

Extensive literature has shown the impact of water scarcity discourses on national policies, however the impact of water scarcity discourses on transboundary water governance has been overlooked. This article contributes to filling this gap by investigating the impact of the water scarcity discourse in the case of Jordan, specifically on three cases of transboundary water governance: the Yarmouk River, the Jordan River and the Disi Aquifer. This article shows that the water scarcity discourse is not enough to explain transboundary water governance, as it needs to be contextualized in the broader context, considering national security, regional geopolitics, inter-sectorial interests, and power asymmetries. This is particularly true when considering that the Arab region has most of its surface waters originating outside of its countries, and transboundary waters represent over two thirds of its overall water resources.
