Jonathan Tummons 《Assessment & Evaluation in Higher Education》2010,35(7):847-857
This paper forms part of an exploration of assessment on one part‐time higher education (HE) course: an in‐service, professional qualification for teachers and trainers in the learning and skills sector which is delivered on a franchise basis across a network of further education colleges in the north of England. This paper proposes that the validity and reliability of portfolio‐based assessment, a key component of many HE programmes in addition to the course being researched here, is contestable. Analysis of the processes of compiling portfolios for assessment, through the conceptual framework of the New Literacy Studies, suggests that the ways in which portfolios are assessed and the ways in which the crucial requisites of validity and reliability are assigned to them, mask complexities and contradictions in their creation by the student. This paper argues for a new, critical analysis of portfolio production and raises a number of questions about the validity, reliability and authenticity of the assessment process that the portfolios reify. 相似文献

One justification offered for legacy admissions policies at universities is that that they bind entire families to the university.
Proponents maintain that these policies have a number of benefits, including increased donations from members of these families.
We use a rich set of data from an anonymous selective research institution to investigate which types of family members have
the most important effect upon donative behavior. We find that the effects of attendance by members of the younger generation
(children, children-in-law, nieces and nephews) are greater than the effects of attendance by the older generations (parents,
parents-in-law, aunts and uncles). Previous research has indicated that, in a variety of contexts, men and women differ in
their altruistic behavior. However, we find that there are no statistically discernible differences between men and women
in the way their donations depends on the alumni status of various types of relatives. Neither does the gender of the various
types of relatives who attended the university seem to matter. Thus, for example, the impact of having a son attend the university
is no different from the effect of a daughter. 相似文献

ObjectiveTo develop a psychometric instrument to evaluate psychological processes associated with institutional abuse and coping strategies used to deal with such abuse.MethodsAs part of a comprehensive assessment protocol, an inventory containing theoretically derived multi-item rational scales which assessed institutional abuse-related psychological processes and coping strategies were administered to 247 Irish adult survivors of institutional child abuse. Exploratory and confirmatory factor analyses were used to derive 6-factor scales, the reliability and validity of which were assessed.ResultsFactor scales to assess the following constructs were developed (1) traumatization, (2) re-enactment, (3) spiritual disengagement, (4) positive coping, (5) coping by complying, and (6) avoidant coping. There were varying degrees of support for the validity of the scales with most support for the traumatization and re-enactment scales.ConclusionsThe Institutional Child Abuse Processes and Coping Inventory (ICAPCI), particularly its traumatization and re-enactment scales, may be used in future research on adult survivors of institutional child abuse because they are currently the only scales that have been developed with this population to provide reliable and valid assessments of these constructs.Practice implicationsThe ICAPCI may be used, cautiously, to assess adult survivors of institutional child abuse. 相似文献

An ongoing controversy in the literature on the economics of higher education centers on whether the success of a school’s athletic program affects alumni donations. This paper uses a unique data set to investigate this issue. The data contain detailed information about donations made by alumni of a selective research university as well as a variety of their economic and demographic characteristics. One important question is how to characterize the success of an athletic program. We focus not only on the performance of the most visible teams, football and basketball, but also on the success of the team on which he or she played as an undergraduate. 相似文献

This paper draws on two case studies from India and China to discuss how and why rapidly urbanizing contexts are particularly challenging for transformative innovation but are also critical sustainability frontiers and learning environments. We argue that lack of understanding and policy engagement with peri-urbanization in its current form is leading to increasing exclusion and unrealized potential to support multiple sustainable urban development goals. Peri-urbanization is often characterized by the neoliberal reordering of space and a co-option of environmental agendas by powerful urban elites. Changing land-use, resource extraction, pollution and livelihood transitions drive rapid changes in interactions between socio-technical and social-ecological systems, and produce complex feedbacks across the rural–urban continuum. These contexts also present characteristic governance challenges as a result of jurisdictional ambiguity, transitioning formal and informal institutional arrangements, heterogeneous and sometimes transient communities, shifts in decision making to distant authorities and the rapid growth of informal market-based arrangements with little incentive for environmental management. These unique features of peri-urbanization may reinforce a lack of inclusion and hinder experimentation, but they can also present valuable opportunities for transformative innovation. This innovation is unlikely to follow the lines of niche management and upscaling but rather should take advantage of peri-urban dynamics. There are possibilities to build new alliances in order to renegotiate governance structures across the rural–urban continuum, to reframe urban sustainability debates and to reconfigure socio-technical and social-ecological systems interactions. 相似文献

Animal toxins that are used to subdue prey and deter predators act as the key drivers in natural food chains and ecosystems. However, the predators of venomous animals may exploit feeding adaptation strategies to overcome toxins their prey produce. Much remains unknown about the genetic and molecular game process in the toxin-dominant food chain model. Here, we show an evolutionary strategy in different trophic levels of scorpion-eating amphibians, scorpions and insects, representing each predation relationship in habitats dominated by the paralytic toxins of scorpions. For scorpions preying on insects, we found that the scorpion α-toxins irreversibly activate the skeletal muscle sodium channel of their prey (insect, BgNaV1) through a membrane delivery mechanism and an efficient binding with the Asp/Lys-Tyr motif of BgNaV1. However, in the predatory game between frogs and scorpions, with a single point mutation (Lys to Glu) in this motif of the frog''s skeletal muscle sodium channel (fNaV1.4), fNaV1.4 breaks this interaction and diminishes muscular toxicity to the frog; thus, frogs can regularly prey on scorpions without showing paralysis. Interestingly, this molecular strategy also has been employed by some other scorpion-eating amphibians, especially anurans. In contrast to these amphibians, the Asp/Lys-Tyr motifs are structurally and functionally conserved in other animals that do not prey on scorpions. Together, our findings elucidate the protein-protein interacting mechanism of a toxin-dominant predator-prey system, implying the evolutionary game theory at a molecular level. 相似文献
