Canonical versus factor analytic perspectives on the structure of associations between the MMPI and the Buss-Durkee Hostility Inventory

A canonical correlational analysis of MMPI profiles versus Buss-Durkee hostility and aggression scales was conducted, resulting in the identification of a general hostility-aggression-maladjustment dimension and three relatively specific aggression-personality relationships. These findings were contrasted with those obtained from a factor analysis of the combination of both sets of scores. Though often used in previous studies of associations between the Buss-Durkee Hostility Inventory and other measures, factor analysis was seen to be less than optimally suited to such a purpose. It was concluded that canonical correlation is preferable to factor analysis when seeking to clarify the multivariate structure of relationships between two sets of variables.     

Protection of animal research subjects

The use of experimental animals, mostly rodents, in biomedical research and especially in oncology and immunology should be acknowledged with respect, recognizing the contribution of animal experimentation in the fascinating scientific progress in these disciplines of research. It is an obligation of the investigator to justify the scientific and ethical aspects of each study requiring the use of animals. The international guiding principles for using animals in biomedical research are well defined and have been distributed worldwide by the International Council for Laboratory Animal Science (ICLAS) since 1956, when this Organization was founded. In Poland the ICLAS philosophy and principles are highly respected and were implemented firstly by the members of the Commission on Biology of Experimental Animals appointed in 1962 by the Department of Medical Science of the Polish Academy of Science in Warsaw. Animal Protection Acts, first proclaimed in 1928 were gradually modified and improved. Actual legislation (enacted in 1997, 2003 and 2005) is consistent with EU Directives (86/609/EEC) and follows the internationally recommended principles that include ICLAS guidelines concerning animal welfare and care condition in biomedical research. The problem of “alternative methods” is briefly discussed. Dr. Donald Boisvert, CCAC — Canadian Council on Animal Care A lecture on the subject of this paper was presented at the 6th International Bioethics Conference entitled ‘The Responsible Conduct of Basic and Clinical Research’, held in Warsaw, Poland, 3–4 June 2005. The author is the National Representative of Polish Academy of Science to the International Council for Laboratory Animal Science (ICLAS) and a Member of the ICLAS Governing Board.

The perceived strength of illusory contours.

Illusory contours are not well understood, partially because a lack of physical substance complicates their specification via physical standards. One solution is to gauge illusory contours with respect to luminance-defined contours, which are easily quantified physically. Accordingly, we chose a metric (perceived contrast) that expresses illusory contour strength in terms of the physical contrast of luminance-defined contours. Using this metric, adult observers adjusted the contrast of a luminance-defined contour until it matched the perceived contrast of an illusory contour. Illusory contour length, inducer size, and inducer contrast all influenced illusory contour strength. The results are adequately explained via low-level visual processes. It appears that matching paradigms can be beneficial in quantitative studies of illusory contours.     

Brief therapy in the Israeli kibbutz

Analysis of results of therapy in an unselected sample of 211 kibbutz patients seen over a three year period by the author in his capacity as kibbutz member and psychiatrist indicated that over 70% of the identified patients responded very satisfactorily to brief therapy. About one-third of the clients did not need more than a single comprehensive therapy session to achieve continuous improvement. In a minority of the cases more than 10 sessions were required. The results were significantly better in cases treated by brief therapy than in the sample treated by long-term therapy, where the pre-treatment severity was determined to be greater. The paper describes the unique aspects of brief therapy in the kibbutz setting, giving an outline of the author's model of intervention, using all components of the individual, family, and community ecosystem.     

Divorce in the Kibbutz: Determinants of emotional adjustment

About two-thirds of a representative sample of kibbutz divorced subjects reached a satisfactory emotional and functioning level of adjustment with a high degree of cooperation between the exspouses by the second postseparation year. This outcome appears to be positively influenced both by a process of habituation and desensitization determined by the continuous physical proximity of the former spouses and by the neutralization of parenting and economic issues as subjects for dispute and litigation.
