Retinal engineering: engrafted neural cell lines locate in appropriate layers.

A major question in central nervous system development, including the neuroretina, is whether migrating cells express cues to find their way and settle at specific locations. We have transplanted quail neuroretinal cell lines QNR/D, a putative amacrine or ganglion cell, and QNR/K2, a putative Müller cell into chicken embryo eyes. Implanted QNR/D cells migrate only to the retinal ganglion and amacrine cell layers and project neurites in the plane of retina; in contrast, QNR/K2 cells migrate through the ganglion and amacrine layers, locate in the inner nuclear layer, and project processes across the retina. These data show that QNR/D and QNR/K2 cell lines represent distinct neural cell types, suggesting that migrating neural cells express distinct address cues. Furthermore, our results raise the possibility that immortalized cell lines can be used for replacement of specific cell types and for the transport of genes to given locations in neuroretina.

Interface between culturally based preferences and genetic preferences: female mate choice in Poecilia reticulata.

The relative contribution of genetic and socio-cultural factors in the shaping of behavior is of fundamental importance to biologists and social scientists, yet it has proven to be extremely difficult to study in a controlled, experimental fashion. Here I describe experiments that examined the strength of genetic and cultural (imitative) factors in determining female mate choice in the guppy, Poecilia reticulata. Female guppies from the Paria River in Trinidad have a genetic, heritable preference for the amount of orange body color possessed by males. Female guppies will, however, also copy (imitate) the mate choice of other females in that when two males are matched for orange color, an "observer" female will copy the mate choice of another ("model") female. Three treatments were undertaken in which males differed by an average of 12%, 24%, or 40% of the total orange body color. In all cases, observer females viewed a model female prefer the less colorful male. When males differed by 12% or 24%, observer females preferred the less colorful male and thus copied the mate choice of others, despite a strong heritable preference for orange body color in males. When males differed by 40% orange body color, however, observer females preferred the more colorful male and did not copy the mate choice of the other female. In this system, then, imitation can "override" genetic preferences when the difference between orange body color in males is small or moderate, but genetic factors block out imitation effects when the difference in orange body color in males is large. This experiment provides the first attempt to experimentally examine the relative strength of cultural and genetic preferences for a particular trait and suggests that these two factors moderate one another in shaping social behavior.

Exploring mindfulness as a culturally sensitive intervention for the Deaf community

Mental health issues are as prevalent in the deaf community as the hearing community, if not more. Yet, Deaf individuals are often treated by mental health professionals less frequently and less effectively. Many systemic barriers exist that influence the lack of services provided to the Deaf community, primarily related to a lack of cultural understanding rooted in perceptions of Deaf individuals. However, the Deaf community may be best understood as a cultural minority, a unique community sharing a distinct culture, history, and language. This paper investigates the effects of systematic barriers and cultural misunderstanding among mental health professions regarding the Deaf community, explores the historical and current mental health problems Deaf individuals most commonly struggle with, and proposes a potential culturally sensitive intervention for the Deaf community based on these factors. To examine these issues, the author conducted a thorough review of Deaf cultural history and values, as well as a review of peer-reviewed articles regarding both Deaf mental health and mindfulness outcome studies. Based on this review, mindfulness may be an effective, culturally sensitive intervention that addresses both cultural and psychological components while working with the Deaf population.

Establishing Culturally Sensitive Therapeutic Communities in Ghana for Individuals with Severe and Persistent Mental Illnesses

This paper makes a proposal for the establishment of therapeutic communities for people with severe and persistent mental illnesses in Ghana. It discusses the history and features of therapeutic communities, as well as the elements that make it compatible with the agenda of the new 2012 Ghana mental health bill. This paper also discusses the present state of mental health care in this West African country and how the establishment of therapeutic communities will promote recovery of people with severe and persistent mental illness, and change the perception of chronic mental illness in Ghana. A discussion of potential modifications of the therapeutic community is offered as well as justifications for maintaining other structural aspects should this establishment materialize in Ghana. The costs of setting up therapeutic communities in this third world country are addressed with the offered conclusion that costs far outweigh the benefits. Finally, given the endeavor of the proposed therapeutic communities to assist in deinstitutionalization of care, cautions are made in this paper to ensure that the trends experienced in the United States with deinstitutionalization are not replicated in Ghana. A proposal is made in the conclusion for Ghana to move past therapeutic communities when developmentally able- to community mental health centers which were in part established to account for some of the fallouts of deinstitutionalization by providing a comprehensive and extensive range of services for people with severe and persistent mental illness.

Incorporating Multiculturalism in Medical Decisional Capacity Assessment

As the demography of the U.S. population becomes increasingly older and culturally diverse, psychologists must develop greater multicultural competency and abilities to provide culturally and linguistically appropriate clinical services. This paper focuses on the dire need for the development of multicultural approach to medical decisional capacity evaluation. The purpose of this paper is to examine the common clinical and ethical dilemmas faced by psychologists when evaluating culturally diverse geriatric population. For instance, the lack of culturally and linguistically appropriate cognitive and functional assessment measures with sound reliability, validity, and normative properties is discussed in detail. This paper introduces possible solutions to the dilemmas and aims to ultimately contribute to increased multicultural awareness within the U.S. healthcare system.

Crossing Blurred Lines: A Training Program to Train Teachers in Appropriate Sexual Boundaries

Boundaries between students and teachers were once clearly defined. Students only interacted with their teachers at school. Currently, however, boundaries are becoming increasingly unclear. As technology advances, students have more venues to interact with their teachers. In addition, teachers are asked to take on more roles in their students' lives. A significant number of teachers and students engage in inappropriate relationships and the possible damage to students is high. Unfortunately, current training programs do not adequately address how teachers can maintain appropriate boundaries with their charges. This paper outlines a proposal for a new training program to fill this gap. This program utilizes training techniques that have been shown to be useful for adult learners as it helps teachers establish and maintain boundaries as well as incorporating elements of effective prevention programs.

Micronutrients and the Sahel: The Need for International Food Aid Reform

The 2012 Food Assistance Convention (FAsC) will replace the 1999 Food Aid Convention (FAC), shortly becoming the new document governing international food aid. This new convention will allow for culturally- and nutritionally-appropriate food purchases, but it lacks sufficient guidance and enforcement mechanisms to ensure the inclusion of micronutrients in food assistance. In conjunction with other United Nations-based programs, reforms focused on cooperation, measurement, and education in micronutrient interventions are recommended for the FAsC framework. These reforms stand to benefit the persistently hungry and micronutrient deficient Sahel region of Africa.
