Field normalized citation rates are well-established indicators for research performance from the broadest aggregation levels such as countries, down to institutes and research teams. When applied to still more specialized publication sets at the level of individual scientists, also a more accurate delimitation is required of the reference domain that provides the expectations to which a performance is compared. This necessity for sharper accuracy challenges standard methodology based on pre-defined subject categories. This paper proposes a way to define a reference domain that is more strongly delimited than in standard methodology, by building it up out of cells of the partition created by the pre-defined subject categories and their intersections. This partition approach can be applied to different existing field normalization variants. The resulting reference domain lies between those generated by standard field normalization and journal normalization. Examples based on fictive and real publication records illustrate how the potential impact on results can exceed or be smaller than the effect of other currently debated normalization variants, depending on the case studied. The proposed Partition-based Field Normalization is expected to offer advantages in particular at the level of individual scientists and other very specific publication records, such as publication output from interdisciplinary research.  相似文献

Fat Capital     
Within the domain of breast reconstruction, abject fat has become a form of biovalue to be harnessed, harvested, and remediated through fat transfer, fat grafting, the therapeutic use of fat stem cells, and fat banking. Each of these technologies deploys fat as capital and promises to return corporeal wholeness following breast cancer surgery. This paper explores the supposed endless malleability of fat and the Promethean dream it represents. In the context of these technologies, the paper asks under what conditions can fat become biovalue; what new corporeal economies are created through the labor of fat; how is this form of biovalue inextricable from the vast circuitry of the breast cancer industry; and how do broader patterns of social dispossession delimit who has access to this dream? It becomes evident that fat gets to be revalued and remediated by women already privileged within circuits of capital, demarcations along lines of race, and notions of normative embodiment. Ultimately, it is the ideal neoliberal subject – one who is ‘able’ to assume responsibility for her own health – that is the inheritor of this dream.  相似文献

Although there is an association between experiencing childhood emotional abuse and feeling hopeless as an adult, it is critical to understand the factors that may be protective in this relationship. The goal of this study was to determine if two protective factors, namely spiritual well-being, including both religious and existential well-being, and positive self-esteem, served to mediate the association between childhood emotional abuse and adult hopelessness. The sample for this investigation was low-income African American women suicide attempters who were abused by a partner in the prior year (N = 121). A path analysis revealed that in this sample, the childhood emotional abuse–hopelessness link was mediated by existential well-being and positive self-esteem, as well as by the two-mediator path of emotional abuse on existential well-being on self-esteem on hopelessness. Results suggested that existential well-being may be a more salient protective factor for hopelessness than religious well-being among abused, suicidal African American women who experienced childhood emotional abuse. Findings highlight the value of culturally relevant strategies for enhancing existential well-being and self-esteem in this at-risk population to reduce their vulnerability to feelings of hopelessness.  相似文献

The purpose of this study is to investigate teachers' core competencies in relation to their innovative teaching performance. Based on the literature and previous studies in this field, four competencies (learning competency, educational competency, social competency and technological competency) are theorised as core competencies for teachers' innovative teaching. A questionnaire on teachers' core competencies and innovative teaching performance was developed and tested. The findings indicate that teachers' educational competency, social competency and technological competency were positively related to their innovative teaching performance. The study also shows that a supportive relationship with colleagues is important for teachers' innovative teaching performance. The theoretical and practical implications are discussed.  相似文献

Rats were trained over a number of sessions on an eight-arm radial maze with eight trials on each session. Each of four arms on the maze contained a different pattern formed by sequences of reward (two pellets) or nonreward (no pellets) over successive trials within sessions. The patterns were single alternation, double alternation, and two patterns in which four rewards or four nonrewards were preceded and followed by two nonrewards or two rewards, respectively. The other four arms on the maze served as control arms and always contained one pellet. It was found that rats tracked all of these patterns when they were required to climb over barriers to enter and leave arms. However, rats showed no ability to extrapolate patterns beyond the training trials. These findings, and a further analysis of arm-choice stereotypy, led to the conclusion that rats tracked by using a trial-number strategy.  相似文献
