This article examines some of the contextual factors underlying the move from teaching to learning in universities over the next two decades. It considers the major characteristics of and elements in emerging learning processes. It assesses the likely impact of the above on personnel policy and practice in universities and suggests some broader organizational issues for universities as a consequence of the analysis. The article draws on research conducted by the author for two recent international studies, sponsored by the Association of European Universities and UNESCO, and on perspectives derived from various strategic evaluation exercises undertaken under the auspices of CRE.  相似文献

We analyze the so-called Socialism of the twenty-first century in which nine South American governments turned to the left over the last 15 years. This South American socialist turn is seen as a delinking from the logics of dependency and pure neoliberalism. To explore the rhetorics that underlie this delinking process, we conducted both a macroanalysis and an intradiscursive rhetorical analysis of the inauguration and most significant speeches of all of the leftist South American presidents elected after 1999. We claim that a common critique of neoliberalism underlies the South American presidents’ speeches, which manifests through specific rhetorics concerning participatory democracy, social inclusion, and environmental protection. When they became transnational, these delinking rhetorics crafted a decolonial critique that calls for more indigenous models of development.  相似文献

This study examined parent reports of behavioral and family functioning for 59 boys with learning disabilities (LD) and 65 nondisabled boys (NLD) of ages 6 to 12 years. Parents completed the Child Behavior Checklist (CBCL) and the Family Adaptability and Cohesion Evaluation Scale (FACES III). Boys with LD were reported as having significantly more behavior problems of both the Internalizing and Externalizing types than NLD boys. Individual scales yielded group differences indicating higher scores (more problems) for the group with LD on the Hyperactive, Schizoid or Anxious, Depressed, and Obsessive Compulsive scales, but no differences on the Aggressive or Social Withdrawal scales. Furthermore, families of boys with LD tended to score more frequently in the extreme (disturbed) range of family functioning. However, boys of families in the extreme range did not have more behavior problems than the boys of other families. The findings suggest that a greater than average proportion of boys with LD are at risk for developing psychological adjustment problems.  相似文献

This study was conducted with 330 Form 4 (grade 10) students (aged 15??C?16?years) who were involved in a course of instruction on electrolysis concepts. The main purposes of this study were (1) to assess high school chemistry students?? understanding of 19 major principles of electrolysis using a recently developed 2-tier multiple-choice diagnostic instrument, the Electrolysis Diagnostic Instrument (EDI), and (2) to assess students?? confidence levels in displaying their knowledge and understanding of these electrolysis concepts. Analysis of students?? responses to the EDI showed that they displayed very limited understanding of the electrolytic processes involving molten compounds and aqueous solutions of compounds, with a mean score of 6.82 (out of a possible maximum of 17). Students were found to possess content knowledge about several electrolysis processes but did not provide suitable explanations for the changes that had occurred, with less than 45?% of students displaying scientifically acceptable understandings about electrolysis. In addition, students displayed limited confidence about making the correct selections for the items; yet, in 16 of the 17 items, the percentage of students who were confident that they had selected the correct answer to an item was higher than the actual percentage of students who correctly answered the corresponding item. The findings suggest several implications for classroom instruction on the electrolysis topic that need to be addressed in order to facilitate better understanding by students of electrolysis concepts.  相似文献

The practice of sexting is becoming increasingly common among college students but has the potential to both initiate productive interactions with others and interfere with relationship development. The purpose of this paper is to report on the findings of a study on sexting among college students and to provide a framework through which practitioners working with this population would be able to effectively intervene. Implications for clinical practice include more specific assessment questions for practitioners, focus on better managing riskier behavior, and guidance toward using technology in relationally responsible and supportive ways.  相似文献

Facing economic pressure, social tensions, global competition and low public confidence, governments can no longer afford to address increasingly complex and interdependent public goals alone or step back and rely on the markets. Instead, they have to work through networks of state and non-state actors to organize existing resources, knowledge and capabilities in the pursuit of public goals. The new paradigm increasingly relies on Information and Communication Technology (ICT) to connect actors to the network and to build, manage and sustain relationships between them. We refer to such ICT-enabled networks as Government Information Networks. This article serves as an introduction to the current issue of Government Information Quarterly on Government Information Networks. The issue comprises twelve cases of such networks selected from the papers submitted to the 5th International Conference on Theory and Practice of Electronic Governance, ICEGOV2010, held in Beijing, China, October 2010. The article also presents a conceptual framework for public administration networks, and applies the framework to describe, analyze and compare the cases, thus relating the volume to the Public Administration literature.  相似文献
