Developing Standard Recommendations (Guidelines) for Genetic Counseling Practice: A Process of the National Society of Genetic Counselors

The National Society of Genetic Counselors (NSGC) supports the development of practice recommendations (guidelines) in the field of genetic counseling. This paper reviews the basic components of NSGC genetic counseling practice recommendations as well as the process for formal adoption of such documents, as approved by the Board of Directors of the NSGC.     

Gerard Manley Hopkins on Planet Earth

Nineteenth-century Jesuit priest and poet, Gerd Manley Hopkins (1844–89), produced poems on natural themes which were not only revolutionary for their structure and style but also disctinctive and forward-looking for their treatment of the environment. In these poems, he presents nature as intrinsically (rather than instrumentally) valuable, God as concerned with the salvation not only of humans but of the environment, and humankind as responsible noy only for polluting the Earth but for participating in its salvation. Christian poets of the twenty-first century need to hees and follow Hopkin's example.     

Solo status, stereotype threat, and performance expectancies: Their effects on women’s performance

Women working in male-dominated environments may find themselves to be the only woman present, and that negative stereotypes about women persist in the environment. This experiment tested women’s performance in solo status (SS: being the only woman present) and under stereotype threat (ST: when women are stereotyped as poor performers). White male and female participants (157) learned information, then tested on it in an opposite-gender (SS) or same-gender group (nonsolo). In addition, the information was described as being traditional math material (ST) or a type of math information impervious to gender stereotypes (no threat). Women performed more poorly in SS than nonsolos, and under ST than no threat. Experiencing both factors was more detrimental to women’s performance than experiencing one or the other. Men’s performance was the same across all conditions. Performance expectancies partially mediated the effect of SS, but not ST, on performance.     

Manifestability and Semantic Realism

Abstract: This paper provides a critical discussion of Alexander Miller's recent attack on antirealist arguments against semantic realism that are based on manifestability requirements. Miller attempts to defend semantic realism against Wright-Hale arguments from manifestability. He does so in reliance on a McDowell type assertion-truth platitude. This paper argues in both general terms and in relation to the details of Miller's argument, that attempts to defend semantic realism while accepting a Dummettian-Wittgensteinian framework on theories of meaning, are misconceived and likely to fail, as I believe is true in Miller's case. Semantic realism is best defended within a context of metaphysical realism, and naturalistic-causal theories of meaning and explanation.     

Facilitation and Retardation of Flavour Aversion Conditioning Following prior Exposure to the CS

Two sets of experiments on flavour aversion conditioning in rats examined the effects of the following factors: the nature of the flavour serving as the conditioned stimulus (CS), which was either a compound of monsodium glutamate, sucrose and quinine, or an elemental flavour, either sucrose or dilute acid; the amount of the CS rats consumed on a single conditioning trial-4 ml or 1 ml; and whether rats had been pre-exposed to the CS before this conditioning trial. There were three main findings. First, conditioning to an elemental CS was unaffected by the amount consumed on the conditioning trial, but conditioning to 1 ml of the compound CS was poorer than to 4 ml. Second, pre-exposure produced a latent inhibition effect if the CS was an elemental flavour, or if rats were allowed to drink 4 ml of the compound solution on their conditioning trial. But, third, pre-exposure facilitated conditioning in rats given only 1 ml of the compound solution as their CS.     

Latent inhibition, context specificity, and context familiarity

In two appetitive licking experiments, thirsty rats were pre-exposed to two stimuli prior to conditioning sessions in which one or both of these stimuli were paired with water. Consistent with other results, latent inhibition was disrupted when conditioning took place in a context different from that in which stimulus pre-exposure had occurred. But in animals given prior exposure to the context of stimulus pre-exposure before the start of stimulus pre-exposure, substantial and equivalent latent inhibition was evident whether or not there was a change of context between stimulus pre-exposure and conditioning. These results are discussed in terms of current theories of latent inhibition.
