Managing professional identity within a changing market environment: New Zealand optometrists’ responses to the growth of corporate optometry

ABSTRACT

This research investigated the effects of changes in the market environment for optometry services and products on the professional identity of New Zealand optometrists. It explored three issues. First, ways participants’ location within either the independent or corporate sectors shaped their professional identities. Second, ways potential ethical conflicts between participants’ healthcare and retailing identities were resolved. Last, participants’ opinions concerning the future of their profession. Twelve male and fourteen female optometrists were interviewed. Nineteen participants worked within independent optometry practices. Seven worked within practices that were part of international optometry chains. Six participants were recent graduates, the rest experienced optometrists. All participants identified primarily as healthcare professionals. All recognised that practising optometry within a commercial market created the possibility of ethical conflicts between healthcare and business imperatives. There were differences in the ways participants managed this boundary, with participants working within corporate optometry seeming more comfortable with the business aspects of their profession. All participants thought the profession was changing and several suggested that the future of independent optometry was limited. The article concludes that recent changes within the market environment of optometry have heightened tensions between optometrists’ medical and entrepreneurial identities and contributed to changing work patterns within the profession.     

A conversation on madness: Foucault and Ripa

Written as a fictitious dialogue between two of this generation’s most prolific social theorists, this unique analysis explores the similarities and divergences of Michel Foucault’s and Yannick Ripa’s scholarship on madness. During an imagined meeting at a local café, a spirited dialogue emerges addressing mutual agreement and unwavering criticism of each author’s perspective of how madness was constructed and managed throughout the classical and Victorian eras. Ripa’s primary motive is to challenge Foucault for ignoring the feminine critique within his over-arching theories of social and patriarchal systems of control. On the other hand, Foucault’s vested interest is to explore Ripa’s narrowed historical scope that he feels was essentially built upon his own scholarship without acknowledgement. Drawing upon a comparative study of Foucault’s History of Madness and Ripa’s Women and Madness, the two theorists engage in a revealing conversation about aspects of political economy, shifting roles of religious ideology, gender effects, the social construction of insanity, and the historical methods of incarceration.     

Explicit Verbal Sexual Consent Communication: Effects of Gender,Relationship Status,and Type of Sexual Behavior

Objectives: College students believe that they are supposed to be explicit and verbal in their sexual consent communication. We examined various contexts to determine when sexual consent is likely to be communicated explicitly and verbally. Method: We surveyed U.S. college students’ (n?=?707) sexual consent communication. Results: We identified contexts when explicit verbal consent cues are less likely—when the person is a woman, when the sexual relationship is casual, and when the sexual behavior is not vaginal-penile intercourse. Conclusions: If sexual consent is contextual, that means communicating consent should not ever be taken for granted.     

Interlitter Response Variability in a Threshold Dose-Response Model

In this article, we extend a previously formulated threshold dose-response model with random litter effects that was applied to a data set from a developmental toxicity study. The dose-response pattern of the data indicates that a threshold dose level may exist. Additionally, there is noticeable variation between the responses across the dose levels. With threshold estimation being critical, the assumed variability structure should adequately model the variation while not taking away from the estimation of the threshold as well as the other parameters directly involved in the dose-response relationship. In the prior formulation, the random effect was modeled assuming identical variation in the interlitter response probabilities across all dose levels, that is, the model had a single parameter to account for the interlitter variability. In this new model, the random effect is modeled as having different response variability across dose levels, that is, multiple interlitter variability parameters. We performed the likelihood ratio test (LRT) to compare our extended model to the previous model. We conducted a simulation study to compare the bias of each model when fit to data generated with the underlying parametric structure of the opposing model. The extended threshold dose-response model with multiple response variation was less biased.     

The legal status of collective bargaining by public school teachers

This paper examines the characteristics of area populations that predict the content of bargaining legislation for public school teachers. The authors provide evidence suggesting that 1) pro-bargaining legislation is correlated with the representation of union members and related workers who benefit from collective bargaining, and 2) the legislation appears to be demanded by career workers as a means of transferring resources away from teachers with relatively short career horizons. An N-chotomous probit model is used to estimate the form of legislation that ranges from bargaining prohibition to prescribed bargaining. Data for the study were obtained from 95 SMSAs in 35 states. We are indebted to Paul H. Rubin and Elchanon Cohn for their substantial contributions to this project. We also received helpful suggestions from Chris Paul and R. Carter Hill.     

Sex Stratification and Male Biography: From Deprivation to Ascendance*

This essay examines some of the implications of early childhood confinement to the household for the development of male character structure. The argument developed is that assignment to women and the household makes small boys outsiders, who receive less comprehensible and positive forms of socialization than small girls. This deprivation experience contributes to the competitiveness and assertiveness of the male response to more favored treatment during the school years, leading to their eventual ascendance, in contrast females greater centrallty and more supportive treatment in early childhood may contribute to "passive" acceptance of male ascendance.     

Mixture model clustering using the MULTIMIX program

Hunt (1996) implemented the finite mixture model approach to clustering in a program called MULTIMIX. The program is designed to cluster multivariate data that have categorical and continuous variables and that possibly contain missing values. This paper describes the approach taken to design MULTIMIX and how some of the statistical problems were dealt with. As an example, the program is used to cluster a large medical dataset.
