A note on parameter estimation for Lazarsfeld's latent class analysis

As the literature indicates, no method is presently available which takes explicitly into account that the parameters of Lazarsfeld's latent class analysis are defined as probabilities and are therefore restricted to the interval [0, 1]. In the present paper an appropriate transform on the parameters is performed in order to satisfy this constraint, and the estimation of the transformed parameters according to the maximum likelihood principle is outlined. In the sequel, a numerical example is given for which the basis solution and the usual maximum likelihood method failed. The different results are compared and the advantages of the proposed method discussed.

Conflict(s) of Interest in Peer Review: Its Origins and Possible Solutions

Scientific communication takes place at two registers: first, interactions with colleagues in close proximity—members of a network, school of thought or circle; second, depersonalised transactions among a potentially unlimited number of scholars can be involved (e.g., author and readers). The interference between the two registers in the process of peer review produces a drift toward conflict of interest. Three particular cases of peer review are differentiated: journal submissions, grant applications and applications for tenure. The current conflict of interest policies do not cover all these areas. Furthermore, they have a number of flaws, which involves an excessive reliance on scholars’ personal integrity. Conflicts of interest could be managed more efficiently if several elements and rules of the judicial process were accepted in science. The analysis relies on both primary and secondary data with a particular focus on Canada.     

Event countertransference and vicarious traumatization: Theoretically valid and clinically useful concepts?

The event countertransference and vicarious traumatization concepts have been introduced in the 1990s to describe the adverse emotional impacts that working with severely traumatized patients may have for the helping professional. These concepts are increasingly popular among trauma therapists. The present paper critically discusses the empirical evidence, theoretical validity and clinical utility of both concepts. Vulnerable trauma therapists may too eagerly embrace the event countertransference and vicarious traumatization perspectives as a cover up for their own failures. Interpersonal communication theory is suggested as a more useful conceptual framework for the analysis of countertransference reactions in therapies with severely traumatized patients.     

Dimensionality of the Rosenberg Self-Esteem Scale and Its Relationships With the Three-and the Five-Factor Personality Models

The interpersonal correlates of the Guilt Inventory (Kugler &; Jones, 1992), which yields scores for state guilt, trait guilt, and moral standards, were assessed. Data collection addressed three issues including the relationships among Guilt Inventory scores and measures of: (a) interpersonal emotions and traits (e.g., shyness, self-consciousness, anger, etc.); (b) the social support network; and (c) ratings of trait guilt, moral standards, and relevant adjectives by friends and family members. Results indicated that trait and state guilt scores were significantly related to various interpersonal measures, most particularly, depression, anxiety, shyness, and loneliness, but only modestly related to satisfaction with social support. Moral standards were generally unrelated to these variables. Others tended to rate participants higher on trait guilt negatively (e.g., higher on contemptuous, angry, guilty, etc.), and participants higher on moral standards in socially acceptable terms (e.g., higher on prompt, self-reliant, moral, and religious). Results are interpreted in view of the frequently cited distinction between social and nonsocial emotions.     

Vygotsky in English: What Still Needs to Be Done

At present readers of English have still limited access to Vygotsky’s writings. Existing translations are marred by mistakes and outright falsifications. Analyses of Vygotsky’s work tend to downplay the collaborative and experimental nature of his research. Several suggestions are made to improve this situation. New translations are certainly needed and new analyses should pay attention to the contextual nature of Vygotsky’s thinking and research practice.
