Rehabilitating care

The feminist ethic of care has often been criticized for its inability to address four problems--the problem of exploitation as it threatens care givers, the problem of sustaining care-giver integrity, the dangers of conceiving the mother-child dyad normatively as a paradigm for human relationships, and the problem of security social justice on a broad scale among relative strangers. We argue that there are resources within the ethic of care for addressing each of these problems, and we sketch strategies for developing the ethic more fully.     

Feminism, law, and bioethics

Feminist legal theory provides a healthy skepticism toward legal doctrine and insists that we reexamine even formally gender-neutral rules to uncover problematic assumptions behind them. The article first outlines feminist legal theory from the perspectives of liberal, cultural, and radical feminism. Examples of how each theory influences legal practice, case law, and legislation are highlighted. Each perspective is then applied to a contemporary bioethical issue, egg donation. Following a brief discussion of the common themes shared by feminist jurisprudence, the article incorporates a narrative reflecting on the integration of the common feminist themes in the context of the passage of the Maryland Health Care Decisions Act. The article concludes that gender does matter and that an understanding of feminist legal theory and practice will enrich the analysis of contemporary bioethical issues.     

The effects of task demands on the equivalence of visual and auditory representations of periodic numerical data

The equivalence of visual and auditory graphical displays was examined in two experiments. In Experiment 1, multidimensional scaling techniques were applied to paired comparison similarity judgments of both auditory and visual displays of simple periodic wave forms. In Experiment 2, a subset of perceptually similar pairs of wave forms was selected as the stimulus set for an AB-X discrimination task in both auditory and visual modalities. Results suggest much greater apparent visual-auditory equivalence for the similarity rating task than for the more difficult discrimination task, implying that one should consider the demands of the task when deciding whether auditory graphic displays are suitable alternatives to more traditional visual displays.     

An automated bisection device for assessing attentional neglect in clinical populations

An automated bisection device (ABD) is described that is designed for use in assessing the direction of three-dimensional neglect in various clinical populations. This device features an apparatus containing two base sections and a connecting rod, on which is located a bisection indicator assemblage that can be moved either by hand or by a calibrated motor-drive system. The indicator assemblage is, in turn, connected to a motor-control box with variable speed settings and a digital readout. The ABD can be used to measure bisection estimations along all three linear axes (lateral, vertical, and depth) by providing visual cues alone, tactile cues alone, or a combination of visual and tactile cues.     

The World-Wide Web as a medium for psychoacoustical demonstrations and experiments: Experience and results

The World-Wide Web provides an inviting opportunity to reach large numbers of people, both as an audience for psychoacoustical discussions and demonstrations and as subjects for psychoacoustical experiments. Such use of the Web poses a unique set of challenges. We present the methodologies used to prepare a multimedia primer in auditory perception at McGill University. As well as instructional material, this primer includes acoustical experiments conducted over the Web. We discuss the response and experiences with this site in general and in a particular class situation at Hanover College.     

The relationship between marital interaction behaviors and affective reactions to one's own and one's spouse's self-evaluation needs

A recent extension (Beach, & Tesser, 1993) of Tesser's self-evaluation maintenance model (SEM: Tesser, 1988) proposed that a person's motivation to feel good about the self, and his or her concern for the partner's need to feel good about the self, can affect the couple's interaction behavior. In the present study, individual differences in the motivation to maintain one's own and one's partner's SEM needs are used to predict the couple's problem-solving discussion behaviors. Fifty-three married couples were videotaped for 20 minutes while discussing an important relationship issue on which there was disagreement. From these video records, husbands' and wives' favorable and unfavorable discussion behaviors were coded. During a subsequent session, couples reported their affective reactions to a number of SEM scenarios recalled from memory, which were used to create an individual difference measure representing the strength in motivation to maintain one's own and one's partner's self-evaluation needs. In general, husbands' and wives' responsiveness to their partners' SEM needs was associated with favorable interaction behavior, whereas responsiveness to one's own SEM needs was associated with unfavorable interaction behavior. The results of this study suggest that the extended SEM model provides an experimental framework that incorporates research directed at both the elucidation of individual differences and the examination of the couple as a unit.     

A case study of conflicting interests: Flemish engineers involved in environmental impact assessment

This article reports of the activities of the working group, Ethics & Engineers, of the Royal Flemish Society of Engineers. More particularly, the ethical problems that engineers face in the preparation of an environmental report are illuminated. Irrespective to which party the engineer belongs, he or she is confronted with the difficult weighting of his or her personal interest, the interests of private companies and last but not least the common good. It is argued that the implementation of a code of ethics and the introduction of courses on engineering ethics into the education of engineers would strengthen the engineer in the fulfilment of his vocation. Dirk Holemans is a bio-engineer preparing a doctoral thesis on the social responsibility of engineers, Herman Lodewyckx teaches ethics and has research interests in professional and applied ethics.     

The Effects of Intra-amygdala Infusion of the AMPA Receptor Antagonist CNQX on Retention Performance Following Aversive Training

The aim of these experiments was to determine whether impaired retention performance in aversively motivated tasks, induced by blockade of amygdala AMPA receptors, is due to influences on mechanisms underlying memory retrieval or to other influences on performance. Rats received either footshock escape training (1 or 10 trials), or no foot shock, in a two-compartment straight alley and bilateral intra-amygdala infusions of the AMPA receptor antagonist CNQX (0.5 μg) were subsequently administered prior to inhibitory avoidance retention testing 8 days later. The CNQX impaired, but did not block, inhibitory avoidance retention performance as indicated by the initial latencies to enter the shock compartment. The animals were then retained in the alley until they remained in the starting compartment for 100 consecutive s and entries into the shock compartment were recorded as errors. In both the controls and CNQX-treated groups, increases in amount of original training resulted in fewer errors, indicating memory for the escape training. Furthermore, regardless of the amount of original training (i.e., 0, 1, or 10 trials), CNQX-treated groups made more errors. Other experiments examined intra-amygdala CNQX effects on reactivity to footshock, locomotor activity, and anxiety. CNQX decreased reactivity to footshock, blocked shock-induced decreases in locomotor activity, and had an anxiolytic effect in an elevated plus maze comparable to that induced by midazolam (0.5 μg). These findings suggest that intra-amygdala infusions of CNQX prior to retention testing affect inhibitory avoidance retention performance following aversive training by altering locomotor activity, reducing sensitivity to footshock, and reducing anxiety. The implications of these findings for hypotheses concerning amygdala function in aversively motivated learning and memory is discussed.
