AP(E)L as a guidance and support mechanism in the Diploma in Social Work

In order to contextualize the multi-interpretative paradigms that characterize the present HE, we propose a model in which the Assessment of Prior and Experiential Learning, AP(E)L, focuses more on assessment and less on accreditation, with a four phase application of the interrelationship between AP(E)L and Learning Development for pre-entry, entry, on-programme and exit of a student's time within a programme of study. In turn, this brings into focus the way experience has now become a contested space that reflects paradigm shifts in the focus of learning and the way learning is to be acknowledged in the new universities. This account details the application of this model within the social work subject area at the University of East London. In many ways, this reflects not only the pre-supposition, central to the AP(E)L policy, that learning should be recognized wherever it takes place, but also the shift from interior intellectual systems to a more open epistemology that has been shaped by the relationship of knowledge producers and knowledge users in specific markets.     

MEASURING SELF-PERCEIVED RACIAL AND ETHNIC DISCRIMINATION IN SOCIAL SURVEYS

The aim of this article is to encourage a research agenda that attends to methodological considerations regarding measuring self-perceived racial and ethnic discrimination in social surveys. Toward this end, the author compared validity of alternative measures of discrimination. The first measure asks whether something unfair or bad has happened because of race and ethnicity, whereas the second measure asks about generic unfair events independent of attribution to race or ethnicity. In a probability sample of 586 Black respondents living in the Detroit metropolitan area interviewed in 1995, it was found that the prevalence of self-perceived racial and ethnic discrimination depended on question framing. Moreover, different respondents were likely to respond affirmatively to explicit versus generic measures of discrimination; importantly, the mental health consequences of self-perceived racial and ethnic discrimination varied by question framing. The results confirmed that the prevalence, correlates, and psychological impact of self-perceived discrimination should be evaluated on the basis of measurement sensitivity.     

BOURDIEU'S CONCEPT OF REFLEXIVITY AS METALITERACY

For Bourdieu, the extent to which agents can attain knowledge of, and negotiate, various cultural fields is dependent upon, and explicable in terms of, two epistemological types. The first is a practical sense (the ‘logic of practice’), while the second involves a sort of conscious comprehension that he names ‘reflexivity’. Bourdieu defines reflexivity as an interrogation of the three types of limitations (of social position, of field and of the scholastic point of view) that are constitutive of knowledge itself. But the reflexive relation to the habitus, the demands and influences exerted by cultural fields, and one's own practices within those fields, cannot be understood simply as something that is obtained by the subject; rather, any reflexive relation to the doxa and illusio of the field must be a constitutive part of that field. This paper identifies a number of principles taken from Bourdieu's work that clarify how, where and why the reflexive ‘surpassing’ of literacy might occur. But we also suggest, contra Bourdieu, that only fields that are informed or characterized by the scholastic point of view are likely to be characterized by the set of conditions constitutive of reflexive knowledge; and that the scholastic point of view is therefore, simultaneously, both a potential impediment to, and a condition (almost necessary) of the production of reflexive knowledge.     

Preschool-Age Adopted Chinese Girls’ Behaviors That Were Most Concerning to Their Mothers

Children's behavioral difficulties are a major source of parental concern. The goals of the current study were to (1) describe preschool-age adopted Chinese girls’ behaviors that were most concerning to their adoptive mothers and (2) examine the relation between children's concerning behaviors and parent/child demographics. Qualitative data from 422 mothers on 480 adopted Chinese girls (M = 44.2 months, SD = 15.2) were collected using three sequenced methods (i.e., open-ended question, follow-ups, and a focus group discussion). These girls were adopted at 3 to 60 months of age (M = 13.8, SD = 8.0) and had lived in the adoptive homes for at least 6 months (M = 30.2, SD = 14.4). Data analysis showed that 242 (57.3%) mothers (representing 274 girls) reported one to three concerning behaviors per child (total = 323 concerns), including behaviors that indicated attachment problems (107 or 33.1%), poor social skills (46 or 14.2%), language/speech problems (42 or 13%), sleep problems (29 or 9%), health/physical problems (24 or 7.4%), and problems in other areas (e.g., potty training) (75 or 23.2%). Further analysis showed that the mothers with prior experience of raising adopted children, but not biological children, were more likely to report concerning attachment behaviors than first-time mothers.     

Social positioning theory and quantum mechanics

Social positioning theory, or an account of the human individual that it grounds, qualifies as a quantum social theory. This is an assessment that I explain and defend in the paper. It is of interest in that, in a world where increasing numbers are seeking to construct quantum social theories, it serves to help demonstrate that this goal can be achieved without giving up on meeting criteria like explanatory intelligibility or power or discarding real-world notions like human (and other) entities. As it turns out, a central feature of the account defended and a core element of the ‘standard’ interpretation of quantum mechanics are found to stand in an interesting, unanticipated and suggestive relation to each other.

Nonstationary regression models with a lagged dependent variable

This paper studies regression models with a lagged dependent variable when both the dependent and independent variables are nonstationary, and the regression model is misspecified in some dimension. In particular, we discuss the limiting properties of leastsquares estimates of the parameters in such regression models, and the limiting distributions of their test statistics. We show that the estimate of the lagged dependent variable tends to unity asymptotically independent of its true value, while the estimates of the independent variables tend to zero. The limiting distributions of their test statistics are shown to diverge with sample size.
