湖北省水资源利用与经济协调发展脱钩分析——基于水足迹视角简

为定量评价湖北省水资源利用与经济增长的协调关系,本文计算湖北省1995-2010年水足迹和水资源利用指标,识别其真实水资源利用情况,分析社会生产、生活对水资源系统造成的压力及其程度,并构建协调发展脱钩评价模型对水资源消耗与经济增长之间的协调关系进行评价。结果表明,湖北省水足迹近16年呈波动上升趋势,农业用水和工业用水是水足迹的主要组成部分,水资源自给率一直保持在95%以上,水资源压力指数近6年逐步上升,水资源利用效率从1995年的7.85元/m³显著提高至2010年的53.72元/m³,GDP增长与水资源消耗由强脱钩的优质协调向弱脱钩的初级协调转化,协调发展状态呈减弱趋势。基于以上研究结论,从水资源管理制度、水权制度改革、价格杠杆调控、农业节水工程建设四个方面提出了促进湖北省水资源利用与经济协调发展的调控策略。     

Do more hours in center-based care cause more externalizing problems? A cross-national replication study

Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in center-based care predicted changes in externalizing problems in toddlers and preschoolers (N = 10,105; 49% female; data collection 1993–2012) in seven studies, including from Germany, Netherlands, Norway, two from Canada and two from the U.S. Race/ethnicity data were only collected in the United States (57% and 80% White; 42% and 13% African-American; 1.2% and 5% Latinx). Meta-analyses showed no association (r = .00, p = .88) between hours in center-based care and externalizing problems.     

Hot and Cool Self-Regulation,Academic Competence,and Maladjustment: Mediating and Differential Relations

This study examined differential and mediating relations between hot and cool self-regulation (M_age = 48.2 months; N = 1,155, 48% girls), first-grade (M_age = 77.5 months) maladjustment (externalizing [EXT] and internalizing [INT] behavior), and first- and second-grade (M_age = 89.5 months) academic competence (AC). Using teacher reported EXT, INT, and AC, partial support for the differential perspective was found in that only hot self-regulation was significantly related to EXT, whereas both hot and cool self-regulation was significantly related to AC. Moreover, hot self-regulation indirectly predicted second-grade AC through first-grade EXT, lending some support for the mediating perspective also. The findings contribute to an understanding of how self-regulation is related to academic and behavioral school adjustment.     

Reshaping academic capitalism to meet development priorities: the case of public universities in Kenya

As colleges and universities have adopted a corporate model in recent decades, debate over the public versus private good associated with higher education has surged. The deliberations have typically been entrenched in Western notions about academia’s contributions to development and scholars have framed academic capitalism dichotomously; a force for good or evil. Far less is known about the market model of higher education in developing nations. We sought to explore this gap by examining how faculty and staff at two public universities in Africa view the intersection of marketization and development.     

Armed with real guns: student unions,student identity,and violence in Côte d’Ivoire

ABSTRACT

African higher education has been the site of repeated contestations over identity. Higher education institutions, as spaces made up of individuals claiming a diversity of identities, are susceptible to conflict when identities are influenced by politicians and paramilitary groups seeking to advance their political agendas on campus through the use of ethnic, religious, and nationalist rhetoric. This qualitative case study of a university in Côte d’Ivoire explored how students engaged in violent political student union activities on campus constructed and enacted their identities through the lens of self-authorship. Findings suggest that student identities are context-dependent and change according to the observer; that self-authorship is difficult due to highly politicized external formulas and social structures; and that, without student support services, vulnerable students may succumb to violent identity enactment and discourse mechanisms.     

Validation of networks derived from snowball sampling of municipal science education actors

Social network analysis (SNA) has been used in many educational studies in the past decade, but what these studies have in common is that the populations in question in most cases are defined and known to the researchers studying the networks. Snowball sampling is an SNA methodology most often used to study hidden populations, for example, groups of homosexual people, drug users or people with sexually transmitted diseases. By use of a snowball sampling approach, this study mapped municipal social networks of educational actors, who were otherwise hidden to the researchers. Subsequently, the resulting networks were validated through interviews with central respondents and by using prior investigations of the municipalities. Our results confirmed that the majority of the designated respondents recognized the resulting sociograms and their own position in these. It was also found that not all predictions based on existing knowledge of the municipalities aligned with SNA data. However, these discrepancies could be explained by development in the municipalities in the time following previous investigations. This study shows that snowball sampling is an applicable method to use for mapping hidden populations in educational settings, but also that qualitative studies are needed in order to interpret the networks in real-life contexts.     

Higher education journals as didactic frameworks

During the last 20 years, we have witnessed a growing interest in research in teaching, learning and educational development in higher education (HE). The result is that ‘Higher Education Didactics’ has established itself as a research field in its own right. This article explores Higher Education Didactics as a framework for academics’ professional reflection on teaching and learning, by mapping the didactic topics in all contributions in four journals in the period 2008–2015. Two of the journals are based in Scandinavia, where the European tradition of didactics (Didaktik) has been highly influential, while the others stem from the Anglo-Saxon curriculum tradition. The mapping shows that all journals are strongly occupied with teaching methods, especially methods grounded in theories of active and social learning. In contrast, didactic categories such as goal, content and assessment are rare topics. Students as participants and learners are a frequent topic in especially one journal, but receive little attention in the other journals. Also, educational technologies receive a varying degree of attention across the journals. Based on the mapping, this article discusses Higher Education Didactics as a framework for professional reflection in HE. It concludes that a broader range of research topics would be desirable and asks for future collaboration on the currently uncharted topics.

University agency in peacebuilding: Perspectives on conflict and development in Kenya

In 2007, Kenya erupted into violence as a result of heavily contested elections. Because identity divisions lay at the heart of the conflict, the nation’s public universities were deeply impacted, at times pitting students, faculty, and staff against one another, and disrupting the ability of Kenyan higher education to contribute to the development process. This qualitative case study explores how faculty and administrators, at two public institutions in a conflict zone, understand and describe their university’s contributions to development. Analyzed through the lens of conflict transformation, the data reveal that the universities changed internal policies and practices to accommodate constituents impacted by the conflict and to cut across conflict lines, and that participants shifted in their thinking about the institution’s internal and external relationships and purposes. The article has two aims. It offers preliminary heuristics for peacebuilding as a university process, providing a framework of practices and policies that engage university constituencies and may transform conflict. It also shows how conflict changed participants’ perspectives about the relationships between themselves, higher education, and development in their country. Further, this article explores a connection between participant beliefs about peacebuilding and development in Kenya.
