A new nursing medium: computer networks for group intervention.

The PLWAs and the caregivers of persons with AD were similar in their adaptation to this new technology as a communication medium with nurses. Both groups availed themselves of the resources, both technological and personal, on the computer network. Although different in demographics, they also were similar in their ability to form and work in a traditional group structure. Nurses have historically intervened with groups, and this article demonstrates that nurses can intervene on a computer network with groups. Yalom's therapeutic factors exist in both non-face-to-face groups and traditional groups. The benefits of this technology to nurses are numerous: they can access clients in an efficient yet supportive manner; they can respond to multiple levels of need in multiple clients; and they can attend to emotional as well as more concrete needs of clients. The benefits to clients are also numerous: they can use the system at a time, frequency, and duration of their choice; they have the opportunity to be supported in self-care efforts versus being in a more dependent role; and they can engage in a normalization of their experiences. Computer networks can enhance nursing's ability to intervene with clients experiencing clinical problems.     

Conducting Research with Lesbian,Gay, and Bisexual Populations: Navigating Research Ethics Board Reviews

The acceleration of research with lesbian, gay, and bisexual (LGB) populations amid existing sexual prejudice and advancing human rights leads to sometime conflicting stances between researchers and ethics boards over acceptable methodological practices. Ethics boards, charged with ensuring the safety of research participants, may engage in ostensibly protective stances regarding potential risks and informed consent that are unwittingly founded upon negative stereotypes of LGB populations. We examine four case studies that demonstrate divergent stances between researchers and ethics boards, researchers’ responses to ethics reviews and their resolution. Based on these cases, we describe themes and strategies for researchers working with LGB populations in responsibly navigating ethics board concerns.     

Health and Cultural Determinants of Voluntary HIV Testing and Counseling Among Middle-Aged and Older Latina Women

The rate of cases of HIV/AIDS in older people is increasing; indeed one out of every four people with HIV/AIDS is over age 50. This study describes the correlates of HIV Voluntary Counseling and Testing (VCT) using structural equation modeling techniques for a sample of 135 middle-aged and middle-aged and older Latinas in South Florida. Over 60% of participants had been tested for HIV. Provider endorsement was found to be the strongest predictor of VCT (odds ratio [OR] = 6. 38), followed by having a clinic as a regular source of healthcare (OR = 3.88). Social work implications are provided.     

The height of two types of generalised Motzkin paths

Consider Motzkin paths which are lattice paths in the plane starting at the origin, running weakly above the x-axis and after n   unit steps returning at the point (n,0)$(n,0)$. The allowed steps are the up and down steps (1,1)$(1,1)$ and (1,−1)$(1,-1)$ respectively and certain horizontal steps. We consider two types of horizontal steps that have attracted recent attention in the literature. First, we consider unit horizontal steps (1,0)$(1,0)$ coloured with k colours, secondly, we look at paths where the horizontal steps are of length k, for a non-negative integer k. Using generating functions, we study the sum of heights of such paths of size n. With the use of the Mellin transform, we find asymptotic expressions for the mean heights as n tends to infinity.
