Cost analysis of the utilization of new vascular grafts

A cost analysis of the utilization of new expensive vascular grafts is performed, applying the methodology of decision analysis to the theoretical case of a sixty year old male patient undergoing femoropopliteal grafting for limb threatening ischemia. The problem is presented graphically as a decision tree, uncertainties are quantified in terms of probabilities and end outcomes are evaluated in monetary terms. This informations is then utilized to calculate cost values associated with alternative actions. Based on initial cumulative patency figures of the new more expensive grafts and the known performance of the older grafts, the initial high expense for the new grafts is justified economically, if the saphenous vein is not available. This analysis, apart from giving an answer to a specific clinical problem, can be viewed as a general model for cost analysis of surgical procedures.     

A mathematical approach for establishing treatment priorities among patients

Medical decision making often utilizes subjective observations to arrive at concrete judgments. The decisions frequently affect who receives scarce medical treatments and, thus, who lives or dies. In this paper, a model health status index is described. It is specific for the problem of choosing patients for hemodialysis or transplantation. Such a health status index may be designed for any medical decision involving such issues as drug treatment priorities, identification of salvageable patients, and selection of patients for scarce medical treatment. This index (1) incorporates a physician's own medical criteria and values, (2) can be modified as the data base improves, (3) assures consistency from decision to decision, and (4) can be developed and used without the help of a mathematician or computer.     

How I learned to stop fearing: Ideological differences in choice of reappraisal content

In down-regulating intergroup fear, an intense emotion common to intractable intergroup conflicts, people may employ various fear-reducing appraisals. Adopting a motivated reasoning perspective, we posited that the contents of individuals’ ideological beliefs influence the contents they employ to down-regulate fear, with rightists preferring ingroup-empowering content and leftists preferring outgroup-weakening content. In Study 1, rightists (vs. leftists) reported greater use of ingroup-empowering reappraisal to down-regulate fear, but no differences emerged in the use of outgroup-weakening reappraisal. Study 2 manipulated the contents’ perceived instrumentality in reducing fear, to examine this as an alternative mechanism. Perceived instrumentality influenced participants’ behavioral content preferences ahead of a fear induction, but the manipulation did not mitigate the right-left differences in ingroup-empowering reappraisal use once participants were confronted with the stimulus, replicating Study 1. Study 3 extended these findings, identifying ideological differences in two additional fear-reappraisal themes and in the attitudinal outcomes of fear regulation.     

With or without you: The paradoxical role of identification in predicting joint and ingroup collective action in intergroup conflict

While we have a rich understanding of the motivations of disadvantaged group members to act collectively with their group, especially the important role played by identification, we know less about the disadvantaged's motivations to engage in joint action with the advantaged. This research examines the role of identification in predicting joint and ingroup collective action in intergroup conflicts. Since joint action inherently diffuses the perception of “us versus them”, we propose that identification predicts ingroup action, but not joint action. We also examine conflict intensity as a moderator, and examine how changing identification is linked to change in support for joint action. We test these hypotheses in a three-wave longitudinal study in the Palestinian–Israeli conflict. Results support our hypotheses, demonstrating that identification positively predicts ingroup action but not necessarily joint action, and that when conflict intensifies, changes in identification are negatively related to joint action with outgroup members.     

Recollections of Menarche: Communication Between Mothers and Daughters Regarding Menstruation

The nature of the communication between mothers and daughters at the time of menarche was examined in an attempt to determine the kinds of messages about menstruation that mothers tend to pass on to their daughters. The sample consisted of 138 women who ranged in age from 26 to 60 years (mean age = 43.2) at the time of the interviews. They were interviewed by 138 students enrolled in Psychology of Women classes taught by the first author. Participants were asked questions regarding their education about menstruation and their experience with menstruation. The content of the responses were analyzed for information about the quality and quantity of mother–daughter communication. The majority of daughters reported that communication with their mothers about menstruation was negative in tone. Eight types of negative messages were identified, including one labeled the grin-and-bear-it message. Two cases are presented to illustrate how the grin-and-bear-it message is related to the traditional feminine gender role and how it might negatively affect a woman's relationship with her mother and with other women.
