CONVERGENT SERIES EXPRESSIONS FOR INVERSE MOMENTS OF QUADRATIC FORMS IN NORMAL VARIABLES

Using relatively recent results from multivariate distribution theory, a direct approach to evaluating the inverse moments of a quadratic form in normal variables is proposed. Convergent infinite series expressions involving the invariant polynomials of matrix argument are obtained. The solution also depends upon a positive scalar which is arbitrarily chosen. For the solution to converge an upper bound upon this scalar is derived.     

The subpoena and a day in court: guidelines for nurses

Psychiatric nurses or therapists may be subpoenaed to appear as direct or expert witnesses. The response must be carefully prepared, and nurses must be aware that testifying in court can be an anxiety-provoking experience. Testifying often involves being an advocate for a client. Clients who have a mental illness, are developmentally disabled, or have a history of abuse or recent violence deserve a conscientious response. The legal process is the avenue for providing safety or empowerment, for assuring that needs are met, and rights are obtained, and being part of that process is an important role. Being prepared for the role is essential.     

Artificiality in Experimental Sociology*

Les auteurs démontrent que la critique du caractère artificiel de l'approche expéri-mentale en sociologie est fondée sur une fausse compréhension des buts de ce type de recherche. A la lumière des objectifs de la recherche expérimentale, l'article examine sous tous ses angles l'objection de ? l'artificialité?. L'avancé fondamental repose sur le fait que le laboratoire est un cadre d'observation parmi plusieurs autres ou la theorie abstraite peut etre mise à l'epreuve empiriquement. Les avantages et désavantages que ce cadre comporte sont reliés à l'objectif de l'en-quete. On discute les consequences qui découlent de cette prise de position. The criticism that sociological laboratory experiments are artificial, we argue, is based upon a misunderstanding of the purposes of this type of research. This paper is an examination of the “artificiality objection,” in terms of the goals of experimental research. The basic point is that the laboratory is one setting among many in which abstract theory may be tested empirically, and that the advantages and disadvantages of the setting are dependent upon the goal of research. Some consequences of this position are discussed.     

Invariance Theorems for Fisher Information

In multivariate and multi-parameter contexts, new expressions for Fisher Information are derived using the copula representation of the joint distribution of random variables. Invariance of Fisher Information to margins of the joint distribution is then demonstrated.     

A robust test for asymptotic independence of bivariate extremes

We show that the existing tests for asymptotic independence are sensitive to outliers. A robust test is proposed. The new test is made stable under contamination through a shrinkage scheme. Simulations show that the new test performs well in the presence of contaminated data while maintaining good properties when there is no contamination. An application to real data shows the added value of our new robust approach.     

Children’s reasoning about unequal gender‐based distributions

Children ages 7 (N = 56, M_age = 7.24, SD = 0.83), 9 (N = 55, M_age = 9.25, SD = 0.52), and 11 (N = 52, M_age = 11.60, SD = 0.79), and emerging adults (N = 50, M_age = 20.76, SD = 0.87) judged distributions of different items to boys and girls, when the items distributed varied by gender valence (related or unrelated to gender norms) and equivalency (equivalent or unequal). Distributions were judged to be acceptable most when the items were consistent with gender norms, especially for participants at ages 7 and 9, indicating that in middle childhood, children judge unequal treatment as fair when it is related to gender norms. Items were judged to be more likable when they were gendered, and likability judgments predicted more positive evaluations of the distributions, even when controlling for age.     

The Use of Common Humanity Scenarios to Promote Compassion in Healthcare Workers

ABSTRACT

The importance of compassion in healthcare is universally acknowledged. However, the factors that enhance compassion are not well understood. The perception of common humanity has been proposed as a prosocial perspective that leads to unbiased universal compassion. There has been a lack of research into the relationship between common humanity and compassion. This study examined the use of common humanity scenarios to promote compassion in healthcare workers. Seventy-five healthcare workers were randomly assigned to two groups and shown a different common humanity scenario. The healthcare workers were asked what effect viewing the videos had on their perception of common humanity and compassion. Thematic analysis was used to identify themes. Four main themes emerged: (a) common bonds; (b) people have the same needs; (c) no one wants to suffer; (d) seeing strangers helping others is motivating. Healthcare workers reported feelings of care, concern, and compassion after viewing common humanity scenarios.

IMPLICATIONS

• Viewing common humanity scenarios appears to lead to enhanced feelings of connection to others and compassion in healthcare workers.

• Using common humanity scenarios may be a useful compassion training strategy in healthcare.

• Further research is necessary to gain a better understanding of how viewing common humanity material influences compassion.

     

Aids and Bereavement

People bereaved by AIDS are likely to be in special need of support by reason of the social situations that accompany this type of loss and the risk of infection in the survivors. Problems associated with grief, depression, and the misuse of medicinal and other drugs are common. Special problems arise when the bereaved are partners, spouses, or parents of the deceased. Issues requiring special attention include emotional overload in both clients and counselors, judgmental attitudes, secrecy, anger, guilt, and the vicious circles that easily arise and can perpetuate problems.
