An application of catastrophe theory to management science process

Practicing management scientists often complain of the alleged irrational behavior on the part of the managers they are trying to serve, particularly when a manager suddenly and unexpectedly shifts behavior from one of support to one of resistance. The authors feel such behavior is only believed to be irrational because the management scientist is using the wrong mental model when projecting past behavioral patterns into the future. This paper attempts to solve this problem by using the newly developed catastrophe theory to develop a different model where sudden shifts in behavior are considered perfectly rational and explainable. The basic implication that is drawn from this new model is that successful implementation of management science depends on a sequence of interactions with the ultimate model user and that care in the structuring of these interactions can greatly enhance the probability of eventual user acceptance.     

Your picture is your bait: use and meaning of cyberspace among gay men

The Internet is seen by many as a form of cyberspace or environment in which to interact and socialise. This research project drew from the data of a quantitative and qualitative study of gay men in Perth, Western Australia. We examined gay men's usage patterns of chat rooms and other social aspects of the Internet to meet sexual partners. We then reviewed in detail the meanings gay men have for the various Internet environments, and the range of friendship, relationship, casual, or esoteric sex-seeking goals. We argue that gay men view and engage with the Internet differently from how they view and engage with other more traditional gay spaces. This different approach influences how interaction between the men, either online or face-to-face, progresses and how assumptions and expectations are built. This has implications for how sexual health promotion interventions determine the appropriate role and relationship they have with these online social spaces.     

Expert Scientific Judgment and Cancer Risk Assessment: A Pilot Study of Pharmacokinetic Data

When high-dose tumor data are extrapolated to low doses, it is typically assumed that the dose of a carcinogen delivered to target cells is proportional to the dose administered to test animals, even at exposure levels below the experimental range. Since pharmacokinetic data are becoming available that in some cases question the validity of this assumption, risk assessors must decide whether to maintain the standard assumption. A pilot study of formaldehyde is reported that was undertaken to demonstrate how expert scientific judgment can help guide a controversial risk assessment where pharmacokinetic data are considered inconclusive. Eight experts on pharmacokinetic data were selected by a formal procedure, and each was interviewed personally using a structured interview protocol. The results suggest that expert scientific opinion is polarized in this case, a situation that risk assessors can respond to with a range of risk characterizations considered biologically plausible by the experts. Convergence of expert opinion is likely in this case of several specific research strategies ar executed in a competent fashion. Elicitation of expert scientific judgment is a promising vehicle for evaluating the quality of pharmacokinetic data, expressing uncertainty in risk assessment, and fashioning a research agenda that offers possible forging of scientific consensus.     

Special Educational Needs: From Disciplinary to Pedagogic Research

A review of research on special educational needs in Britain over the last two decades indicates that two concerns have been paramount. First, there has been an attempt to broaden research styles in response to the growing critique of traditional positivist research. Secondly, the problem of the perceived gap between theory and practice has been addressed. Developments have included the use of small-N studies within a positivist framework, the adoption of qualitative research strategies and the critical perspectives of sociologists. It is argued here that such developments have been largely restricted to what Michael Bassey refers to as 'disciplinary' research, neglecting the 'pedagogic' research associated with the growth of practitioner research in other areas of education. The article examines both why teacher research has been relatively neglected in special education and the kinds of contributions it might make.     

Discourse Analysis in Career Counseling and Development

Discourse analysis can be used to understand and interpret culturally and socially produced meanings regarding work and to outline how specific rules and conventions can configure meaning production of work in context. The implications of some core concepts in discourse analysis pertinent to career counseling are explored, including discourse, deconstruction, power/knowledge, psy‐complex, ideology, and identity. Such an exploration has the potential to initiate a process of critical self‐reflection in career counseling and development so as to enhance ethical, fair, and inclusive practices in the field.     

Efficiency Bounds for Missing Data Models With Semiparametric Restrictions

This paper shows that the semiparametric efficiency bound for a parameter identified by an unconditional moment restriction with data missing at random (MAR) coincides with that of a particular augmented moment condition problem. The augmented system consists of the inverse probability weighted (IPW) original moment restriction and an additional conditional moment restriction which exhausts all other implications of the MAR assumption. The paper also investigates the value of additional semiparametric restrictions on the conditional expectation function (CEF) of the original moment function given always observed covariates. In the program evaluation context, for example, such restrictions are implied by semiparametric models for the potential outcome CEFs given baseline covariates. The efficiency bound associated with this model is shown to also coincide with that of a particular moment condition problem. Some implications of these results for estimation are briefly discussed.     

This Harlem life: black families and everyday life in the 1920s and 1930s

This article uses Probation Department files to reconstruct the lives of five ordinary residents of Harlem. It highlights what that black metropolis offered those outside the political and cultural elite, who have dominated historical scholarship, showing how ordinary blacks negotiated the challenges of life in northern neighborhoods, and drew on institutions and organizations, to establish and sustain new lives. We offer the kind of individualized perspective on everyday life that other scholars have provided for high culture, but which does not exist for other realms of existence in Harlem, even in early twentieth century sociological studies of black life. Where scholars seeking to distinguish the neighborhood from a slum have pointed to the prevailing pride and self-confidence of its residents, this article directs attention to more immediate, concrete supports that sustained and enriched life in Harlem. Relationships with spouses, children, siblings and cousins sustained individuals faced with the social reality of living in overcrowded, deteriorating, disease infested housing, subject to the racism of white police, politicians and employers; so too did friendships made in nightclubs, speakeasies, dances and movie theatres, and membership of churches, fraternal organizations, social clubs, and sports clubs and teams.     

SCALING GOVERNMENTALITY

This article explores contemporary uses of museum co-production for public policy through a sustained theoretical engagement with Tony Bennett's work on museums as an ‘object of government’. The specific focus is a theoretical discussion of the ‘logic of culture’ as it relates to new UK policy uses of participants' ‘experience’ as the desired site of authenticity at the very same time as the process of expressing this authenticity is located as a site for reform. It is argued that Bennett mobilizes two techniques of scale (fixing the analytic lens of governmentality and drawing on a strong scalar correspondence of power) in order to secure a relatively disciplinary reading of governmentality and to foreclose the resistant possibilities of cultural politics. Drawing on the differences between practices associated in UK museums with ‘access’ (which works through the dis-intensification of the difference between the museum and everyday life) and with ‘social impact’ (which requires a re-intensification of this difference in order to increase the visibility of effect), this article concludes by countering Bennett's more disciplinary uses of Foucault with the Foucault of ‘The Subject and Power’. It is argued that the ‘logic of culture’ can be calibrated to varying intensities in considering the coming-into-relationship between the museums and those-to-be-involved. It is specifically argued – following Foucault's spatializaton of ‘thought’ as distance (limit-attitude) and ‘counter-conduct’ as proximity – that the ‘logic of culture’ might be actively re-calibrated to use the spatialized dynamic of distance and proximity to create spaces which might allow the museum and its associated policy – not just those involved – to be affected by the co-production encounter.
