Shape and orientation of arterial loops in cat sartorius muscle.

A method is described to quantify the shape and orientation of vascular loops (arcades). Shape is characterized by an ellipticity factor, calculated from area and perimeter values. Orientation is measured as the angle formed by the great axis of the loop with the muscle fibers. These parameters were calculated for 772 arteriolar loops of the cat sartorius muscle. The results show that, on the average, the ellipticity factor is a linear function of the number of segments. The observed values change in the opposite direction from the expected values for regular polygons. Simple calculations are presented to rectify this discrepancy. Most loops are oriented parallel to the muscle fibers.

The HIV/AIDS pandemic, African traditional values and the search for a vaccine in Africa.

The response to the HIV/AIDS pandemic in Africa has so far ignored important traditional African values and attitudes toward disease and commerce. These values and attitudes are significantly different from the libertarian, market-driven, profit-oriented values and practices of important sectors of the Western world. To deal with this epidemic, the world should consider respect for, and possibly even adoption of those African values, which provide for people in genuine need, irrespective of their ability to pay. HIV/AIDS vaccine research indigenous to Africa is also not always taken seriously, and struggles to find adequate funding for such research within or outside of the continent have been extremely difficult. A better appreciation of knowledge systems and values indigenous to the African experience is important in the fight against the HIV/AIDS pandemic.

Value correlates of preventive health behavior.

In a postal survey, 113 respondents completed the Rokeach (1967) Terminal Value Survey with an additional value, "health," and 15 questions about their preventive health behavior (PHB). Correlation and regression analyses showed that health and other values were related to overall PHB, suggesting that health researchers should also consider the role of values other than health. In consistency with Rokeach's theory, respondents who reported good PHB valued health more than did those who reported poor PHB. There were also significant differences in the general value orientation of extraversion versus introversion. Health educators might apply knowledge of such differences to a value confrontation program. As hypothesized, regression analyses for each of the 15 PHB items showed that health value was more likely to be predictive of behavior that involved a direct rather than indirect risk to health. For behaviorally consistent respondents, health value was correlated with both types of behavior, whereas for behaviorally inconsistent respondents, health value was only correlated with direct-risk behavior. This suggests that health researchers should ensure that subjects are aware of the relevance of a PHB to health before concluding that health value, or a related construct, cannot be predictive of PHB. Finally, the regression analyses suggest that it was possible to predict specific PHBs from the more general value ranks. This finding raised questions about the validity of Ajzen and Fishbein's (1977) notion of levels of specificity and provided further support to Rokeach's value theory.

Values and therapy orientations of psychotherapy trainees: a twelve-year update.

Psychotherapy orientations, self-declared fortes in conducting therapy, and interpersonal values were studied among psychiatry residents and psychology interns in the late 1960s and early 1980s. A distinct pattern of psychotherapy orientations and fortes emerged which transcended professional backgrounds and proved stable across generations, despite some interactions between training and time. Subjects' professed areas of expertise were closely aligned with their beliefs about what methods are most effective in psychotherapy, and both these variables were significantly associated with their value profiles. The correlation matrix suggested a three-factor model of related psychotherapy and value orientations surrounding the three predominant modalities: insight, corrective emotional experiences, and learning. It was proposed that the data support the importance of value dimensions in contributing to psychotherapists' adoption of specific treatment strategies and their developing expertise in corresponding techniques.

Ethics orientation as a mediator of organizational integrity in health services organizations.

Increasing scrutiny of ethical misconduct by federal and state agencies has prompted health services organizations to adopt codes of ethics and institute legal compliance programs. However, there is little understanding of the impact of ethics programs or the manner in which program elements act to enhance organizational integrity. This study examined the effect of five ethics program elements on organizational integrity and the mediating role played by ethics orientation in this relationship. It found that program elements influence organizational integrity by engendering among employees a values orientation, a compliance orientation, or both. Furthermore, program elements that induced both orientations have a larger impact on integrity. These findings have important implications for health services managers involved in designing and implementing an ethics program.

Pride and purpose as antidotes to black homicidal violence.

The incidence of black male homicide is a major public menace. The lowest incidence of black male homicide was when the black power movement was visible and flourishing. Psychohistorical data support the contention that racial pride is an effective means for regulating intragroup tensions. In the absence of an Afrocentric orientation that promotes community power and self-determination, the need for self-reliance is eroded by value illnesses.The value orientation of the black movement supplied the pride used to obtain academic success, to reduce juvenile delinquency, and to help Afro-Americans to structure their lives for personal satisfactions. Blackness has always been about personal power and social control, but society does not allow much access to either for Afro-Americans. As a consequence, stress from racism is severe, asymptomatic, and multi-faceted. The best antidote to black homicidal violence comes from a pro-social effort based upon a self-image that gives a feeling of positive accomplishment and appreciation. Afrocentric pride promotes or enhances pro-social behavior.

Disavowal of the behaviorist paradigm in nursing education: what makes it so difficult to unseat?

The literature is replete with calls for disavowal of the behaviorist paradigm in nursing education, a paradigm charged with producing successive generations of passive learners who are incapable of instigating much needed and long overdue reforms within the health care system. Only rarely has this call been challenged by nurse educators. In this article, the role of a paradigm in delineating the nature of and solutions to significant problems within a scientific community is explored. I posit that the current eschewal of behaviorism by nurse educators stems not from its failure to solve significant problems in nursing education but rather from an apparent shift in value orientation--a shift from effecting learning (and health) outcomes to effecting social change. Despite this seeming shift in values, effecting learning outcomes is still held to be an essential aspect of nursing education, and it is because of this, I argue, that the behaviorist paradigm is so difficult to unseat.

Manager-physician relationships: an organizational theory perspective.

Manager-physician relationships are a critical determinant of the success of health care organizations. As the health care industry is moving toward a situation characterized by higher scarcity of resources, fiercer competition, more corporitization, and strict cost-containment approaches, managers and physicians should, more than ever, work together under conjoint or shared authority. Thus, their relationship can be described as one of high rewards, but also of high risk because of the wide range of differences that exist between them: different socializations and trainings resulting in different worldviews, value orientation and expectations and different cultures. In brief, managers and physicians represent different "tribes," each with its language, values, culture, thought patterns, and rules of the game. This article's main objective is to determine the underlying factors in the manager-physician relationship and to suggest ways that make this relationship more effective. Four different organizational perspectives will be used. The occupational perspective will give insights on the internal characteristics of the occupational communities of managers and physicians. The theory of deprofessionalization of physicians will also be discussed. The structuring perspective will look at the manager-physician relationship as a structure in the organization and will determine the effects of contextual factors (size, task uncertainty, strategy, and environment) on this relationship and the resulting effect on performance and effectiveness of the organization. The culture and control perspective will help detect the cultural differences between managers and physicians and how these interact to affect control over the decision-making areas in the hospital. The power, conflict, and dialectics perspective will shed the light on the conflicting interests of managers and physicians and how these shape the "power game" in the organization. Consequently, a theoretical model of manager-physician relationships that encompasses all these perspectives is developed.

Alcoholism counseling in Norway: an American social worker's experience.

This article describes a cross-cultural experience in teaching alcoholism treatment skills and therapy techniques. The current treatment model in America has to be shaped to the requirements of the local scene. The immediate problem was to import a disease-oriented model of alcoholism to a land where most people view alcoholism in terms of individual moral failing. The Norwegian cultural value orientations are defined; then the alcoholism treatment adaptation across language and custom is discussed.

Professional identity: values embedded in meaningful nursing practice.

The main research question addressed in this two-phase descriptive study was 'What are the values underlying nurses' professional identity as expressed through what is meaningful in nurses' work? The first phase was a survey of 767 randomly selected nurses with one, five, and 10 years of experience in nursing, and in the second phase data on work-meaning were obtained from a convenience sample of six nurses by in-depth interviews eliciting nurses' stories about providing care to patients. Content analysis of survey-data revealed that the nurses held both other-oriented and self-oriented values, i.e. moral and work values. Human dignity and altruism were the most prominent moral values, whereas the most significant work-values were intellectual and personal stimulation. The interview-data, analysed by means of hermeneutic and narrative analysis, revealed a greater diversity in value-expressions compared to the survey-data. Altruism, the moral orientation of care, was the overall philosophy, and human dignity appeared as a core value. The nine additional values appeared to be linked to human dignity either by arising from it and/or being aimed at preserving this basic value.

Values and self-esteem in three generations of men and women.

Similarities and differences in values within families across three generations were examined. The relationship between values and self-esteem was also investigated. Sixty inter-generational triads (30M;30F) rated 14 values on a semantic-differential scale. The hypotheses of generational similarities in long-term, central (in Rokeach's terms, terminal) values and of generational differences in short term, specific (Rokeach's instrumental) values were generally supported. However, the hypothesized interactions of self-esteem and generation with values were only minimally supported by these data. There were no generational differences in the terminal values Equality, An Exciting Life, Freedom, and A Sense of Accomplishment. The oldest generation rated the instrumental values Ambition, Capability, Independence, and Intelligence higher than did the other generations. In addition, they rated the more work-oriented values of Education, Money, Success and Work highest. These findings are discussed as possible cohort rather than as age effects. Women rated Ambition, Education, and Intelligence more highly than men.

Cultural differences in the predictors of depression.

This study examined a number of psychosocial factors thought likely to contribute to depression among ethnic Korean and Caucasian students. As hypothesized, Koreans (n = 61) were more depressed than Caucasians (n = 69). Stepwise multiple regression analysis revealed different models for predicting depression in the two groups. Value orientations, a neglected element in the prevailing stress paradigm, contributed substantially to variation in depression, especially among Koreans. Two measures of parental values and three coping strategies accounted for a striking 44% of the variance in Korean youths' depression. Perceived parental traditionalism, the strongest predictor, was associated with higher depression; and perceived parental modernism, with lower depression. For Caucasians, in contrast, only 13% of the variance in depression could be accounted for; and the two significant predictors were academic stress and respondents' own modern values (the latter associated with fewer symptoms). The findings of this study argue for greater attention to the importance of values in studying adaptation to stress.

Progression from enrolled to registered nurse (2): Charting the conversion.

Part 2 of the study focuses on the three value instruments mentioned in part 1 (Hembrough & Sheehan 1989). The students were asked to complete the three value-oriented tasks on seven occasions throughout the duration of the course. The data obtained provided some evidence regarding the stability of the students' values. The study also identifies and comments upon the most persistently and popularly chosen value descriptors. Cameos relating to the professional and personal self-perceptions of each student are also presented.

Lesbian/feminist orientation among male-to-female transsexuals.

Autobiographical case studies of two male-to-female transsexuals reveal a pattern of strong female identity couples with lesbian sexual-affectional preference and feminist value orientation. For both informants there is evidence of social concern and activism from an early age, which led them to perceive their gender dilemmas in a political as well as personal way. This case material challenge the notion that transsexuals are necessarily "sexualy Uncle Toms" and demonstrated that male-to-female transsexuals (like genetic women) can achieve an affirmative lesbian identity; it suggests more generally that the development of sexual identity is an ongoing, lifelong process.

Mother Teresa versus Ebenezer Scrooge: mortality salience leads proselfs to endorse self-transcendent values (unless proselfs are reassured).

Recently, Jonas, Schimel, Greenberg, and Pyszczynski demonstrated that mortality salience (MS) increased contributions to (an ingroup) charity (i.e., the Scrooge effect). The authors examined whether individual differences in social value orientations would moderate the Scrooge effect. In line with an Ebenezer shift hypothesis, proselfs were less likely than prosocials to endorse self-transcendent values in a dental pain control condition but were indistinguishable from prosocials in an MS condition as proselfs increased endorsement of self-transcendent values under MS (Experiments 1 and 2a). However, when participants gave their impressions of an unfavorable prosocial or a favorable proself prior to the MS manipulation, proselfs were again less likely than prosocials to endorse self-transcendent values (Experiments 2a and 2b), suggesting that proselfs are unlikely to transform into prosocials under conditions of MS when given reasons to disidentify with prosocial values or identify with proself values.

Decision-making in clinical nursing: investigating contributing factors.

BACKGROUND: This article describes the results of a study which investigated the contextual factors influencing clinical decision-making. Education and experience have been suggested by some as having a positive effect on clinical decision-making, and have been listed as being of high importance. Values, knowledge, clinical setting and stress have also been identified as being important to decision-making, with various rankings given by different researchers. AIM: The study was undertaken to determine relationships between occupational orientation (value to role), educational level, experience, area of practice, level of appointment, age and clinical decision-making in Australian nurses. The predictive ability of each factor on clinical decision-making was determined. METHOD: This correlational study examined Australian nurses' decision-making about some common nursing interventions and 'occupational orientation', educational level, experience, level of appointment, area of clinical speciality and age. A model was constructed using stepwise selection regression to predict the 'weight' of each variable in clinical decision-making. RESULTS: Education and experience were not significantly related to decision-making. The factor that accounted for the greatest variability to clinical decision-making was holding a professional occupational orientation, followed by level of appointment, area of clinical speciality, and age in that order. CONCLUSION: In contrast to other studies, experience and educational level were not found to influence decision-making strongly, the value of role was the most significant predictor. The model developed, however, only accounted for a low amount of variability in decision-making. The findings indicate that there are other factors affecting clinical decision-making that still require identification.

East meets west: some ethical considerations.

Japan, one of the most developed and industrialized countries in the world, may appear totally Westernized, but Japan has a culture of traditional customs and beliefs. This paper sheds light on the confusion of value orientations among Japanese nurses whose professional socialization is heavily influenced by Western culture and whose personal life depends on traditional culture. Examples of Japanese culture-bound values clarify the differences between Western and Japanese cultures. The importance of engaging in value clarification and analyzing the ethical principles behind decision-making is noted.

Addressing cultural incongruities of advance directives.

Shared meanings and socially constructed realities have great significance to individuals and families facing critical illness, pain, suffering, or death. Actions are often based on the context of the professional and dominant societal culture. The concept of Advance Directives is consistent with the dominant value orientation in the American culture of self-reliance and individualism, which places a high premium on self-determination and control of one's own destiny. However, this value is not always consistent with the dominant cultural views of particular sick or dying individuals. Thus, at a time when individuals and their families need the most support, institutionalized care often creates incongruities and meaninglessness.
