Why is the History of Heterosexuality Essential? Beliefs About the History of Sexuality and Their Relationship to Sexual Prejudice

Heterosexual people with more positive attitudes to lesbians and gay men generally believe that homosexuality is immutable, is not a discrete social category, and that homosexuality exists in all cultures and time periods. Equivalent beliefs about heterosexuality and beliefs about components of sexuality have been less often researched. 136 people with diverse sexualities described heterosexuality as more universal across history and culture than homosexuality (Study 1). 69 heterosexual-identified participants similarly believed that love, identity, behavior, and desire were more historically invariant aspects of heterosexuality than of homosexuality (Study 2). Less prejudiced participants thought all components of homosexuality—except for identity—were more historically invariant. Teasing apart beliefs about the history of components of heterosexuality and homosexuality suggests that there is no “essential” relationship between sexual prejudice and the tension between essentialist and constructivist views about the history of sexual identity.     

Will the ASA's Efforts to Improve Statistical Practice be Successful? Some Evidence to the Contrary

ABSTRACT

Recent efforts by the American Statistical Association to improve statistical practice, especially in countering the misuse and abuse of null hypothesis significance testing (NHST) and p-values, are to be welcomed. But will they be successful? The present study offers compelling evidence that this will be an extraordinarily difficult task. Dramatic citation-count data on 25 articles and books severely critical of NHST's negative impact on good science, underlining that this issue was/is well known, did nothing to stem its usage over the period 1960–2007. On the contrary, employment of NHST increased during this time. To be successful in this endeavor, as well as restoring the relevance of the statistics profession to the scientific community in the 21st century, the ASA must be prepared to dispense detailed advice. This includes specifying those situations, if they can be identified, in which the p-value plays a clearly valuable role in data analysis and interpretation. The ASA might also consider a statement that recommends abandoning the use of p-values.     

Net migration and migration effectiveness: A comparison between Australia and the United Kingdom, 1976–96

This paper explores the impact of net migration in Australia and the United Kingdom using measures of migration effectiveness computed from period-age migration data for four consecutive five-year periods. Results reported in Part 1 of this paper (Stillwellet al. 2000) suggest that while the overall effectiveness of net migration at the scale of city regions has declined over the twenty-year period in both countries, important geographical variations are evident. Part 2 considers how patterns of migration effectiveness vary by age and presents a single classification of all the city regions on the basis of age-specific effectiveness. More detailed analysis includes spatial patterns for particular age groups and net migration profiles of selected regions. Cohort effects are shown to be important for explaining changes between time periods in these regions.     

Working with emotion: Issues for the researcher in fieldwork and teamwork

This paper addresses the role of emotion in the qualitative research process and in particular, the effects of emotional experiences on the researcher. Drawing briefly on the literature, we show the importance of emotion for understanding the research process. Whilst this literature acknowledges the emotional risk for research respondents, there is little evidence providing in-depth understanding of the emotions of the researcher. We consider theoretically and empirically, the significance of emotion throughout the duration of a research project. Using our own personal experiences in the field, we present a range of emotional encounters that qualitative researchers may face. We offer suggestions for research teams who wish to develop strategies for 'managing' emotion and effectively utilizing 'emotionally-sensed knowledge'. We conclude that unless emotion in research is acknowledged, not only will researchers be left vulnerable, but also our understandings of the social world will remain impoverished. The challenge therefore is how to construct meaning and develop understanding and knowledge in an academic environment that, on the whole, trains researchers to be rational and objective, and 'extract out' emotion.     

The Statistics of Simulating Chaos

When simulating a dynamical system, the computation is actually of a spatially discretized system, because finite machine arithmetic replaces continuum state space. For chaotic dynamical systems, the discretized simulations often have collapsing effects, to a fixed point or to short cycles. Statistical properties of these phenomena can be modelled with random mappings with an absorbing centre. The model gives results which are very much in line with computational experiments. The effects are discussed with special reference to the family of mappings f (x)=1-|1-2x|,x [0,1],1,<,,<,. Computer experiments show close agreement with predictions of the model.     

Effect of perceived cost on judgments regarding the efficacy of investment

Three experiments examined the effect of costs associated with investments on the judgments of the causal effectiveness of those investments, and on the type of information utilised when making those judgements. Using operant conditioning technology, in an experimental analogue of making economic investments, it was found that greater costs associated with an investment reduced the judgement about the effectiveness of the response (Experiment 1). Greater investment costs tended to bias the subject toward using information integrated over a longer period of time; whereas low costs tended to produce judgements made on the basis of the conditions prevailing immediately prior to the return being acquired (Experiments 1–3). The effect of cost was modulated by the subjects' own financial background. The same absolute cost being treated as “greater” by those from less wealthy backgrounds compared to those from more affluent backgrounds (Experiments 2 and 3). These results suggest that as well as the nature of the schedule relating investment to return, the perceived cost of the investment determines the manner in which it is judged with respect to its efficacy.     

Social workers in private practice: What are they really doing?

At one level, private practice may represent a fairly evolved manifestation of the expanded professional growth and sophistication of the individual social worker who embarks upon this highly individualized proprietary enterprise. However, on a larger scale, this widespread shift toward private practice may indicate a collective disenchantment with agency practice per se and represent a concerted attempt to redefine the fundamental aims and values of social work practice.
