Renegotiating Aquinas

While Roman Catholic feminist ethicists typically endorse moral realism and crosscultural standards of justice, they also have been influenced by the postmodern interrogation of abstract reason and moral universalism. As theologians writing after the Second Vatican Council, they are increasingly sensitive to the communal and ecclesial dimensions of morality and of Christian ethics, and to the integral relation of Christian faith and ethics. This essay will consider two approaches to Catholic feminist ethics that differ in the relative weight they give to constructive work for social justice (realist gender justice ethics), or to the grounding of ethics in prayer and mysticism (postmodern gendered faith ethics). Using critical feminist reappropriations of the theology and ethics of Aquinas as examples, this essay will argue that the two approaches are overlapping and interdependent.     

Rat choice in rapidly changing concurrent schedules

In two experiments, experimentally naïve rats were trained in concurrent variable‐interval schedules in which the reinforcer ratios changed daily according to a pseudorandom binary sequence. In Experiment 1, relative response rates showed clear sensitivity to current‐session reinforcer ratios, but not to previous sessions' reinforcer ratios. Within sessions, sensitivity to the current session's reinforcement rates increased steadily, and by session end, response ratios approached matching to the current‐session reinforcer ratios. Across sessions, sensitivity to the current session's reinforcer ratio decreased with continued exposure to the pseudorandom binary sequence, contrary to expectations based on previous studies demonstrating learning sets. Using a second group of naïve rats, Experiment 2 replicated the main results from Experiment 1 and showed that although there were increases over sessions in both changeover rate and response rate during the changeover delay, neither could explain the accompanying reductions in sensitivity. We consider the role of reinforcement history, showing that our results can be simulated using two separate representations, one local and one nonlocal, but a more complex approach will be needed to bring together these results and other history effects such as learning sets and spontaneous recovery.     

Parents‐in‐law's topic avoidance: Understanding the role of interaction goals and relational characteristics

Utilizing dual logic from a multiple goals and relational turbulence theory, this study examined parents‐in‐law's interaction goals for topic avoidance with their children‐in‐law. Data from 159 parents‐in‐law revealed that multiple and conflicting goals were associated with parents‐in‐law's topic avoidance. Furthermore, relational parameters (i.e., relational uncertainty and partner influence) were associated with the goals in‐laws pursued. Results augment theorizing on a multiple goals perspective, relational turbulence, and topic avoidance, as well as theoretically ground the study of in‐law communication.     

Provider Conscientious Refusal of Abortion,Obstetrical Emergencies,and Criminal Homicide Law

Catholic doctrine’s strict prohibition on abortion can lead clinicians or institutions to conscientiously refuse to provide abortion, although a legal duty to provide abortion would apply to anyone who refused. Conscientious refusals by clinicians to end a pregnancy can constitute murder or reckless homicide under American law if a woman dies as a result of such a refusal. Such refusals are not immunized from criminal liability by the constitutional right to the free exercise of religion or by statutes that confer immunity from criminal homicide prosecution. Core principles of the rule of law require the state to protect the lives of all persons equally and to place the life and health of persons above any the interests of providers have in moral integrity or in respecting the moral status of prenatal humans. In some states criminal liability related to conscientious objection also applies to corporate hospital officials.     

Die Rechtsansichten der Eurasier -- Rechtsordnung oder Wertordnung?

In their juridical doctrines, the members of the Evrazijstvo movement advocated the idea of a Russian special path criticizing at the same time the formalism and coldness of the western conception of law, based principally on Roman law. Their views are characterized by an evident priority accorded to justice over law, to the order of values over legal order.

The Ethics of Sex: A Call to the Gay Community

Addresses the gay community and suggests three principles to govern contemporary sexual behavior: first, the presumed goodness of homosexual relationships; second, an updated version of natural law, that one do what is healthy and wholesome, as determined by the best available opinion of the day, which scientific research provides; third, a developmental principle, that all are not capable of the same level of interpersonal and sexual relationships. Discussion proposes both negative and positive guidelines for sexual practice.     

Dynamic response-by-response models of matching behavior in rhesus monkeys

We studied the choice behavior of 2 monkeys in a discrete-trial task with reinforcement contingencies similar to those Herrnstein (1961) used when he described the matching law. In each session, the monkeys experienced blocks of discrete trials at different relative-reinforcer frequencies or magnitudes with unsignalled transitions between the blocks. Steady-state data following adjustment to each transition were well characterized by the generalized matching law; response ratios undermatched reinforcer frequency ratios but matched reinforcer magnitude ratios. We modelled response-by-response behavior with linear models that used past reinforcers as well as past choices to predict the monkeys' choices on each trial. We found that more recently obtained reinforcers more strongly influenced choice behavior. Perhaps surprisingly, we also found that the monkeys' actions were influenced by the pattern of their own past choices. It was necessary to incorporate both past reinforcers and past choices in order to accurately capture steady-state behavior as well as the fluctuations during block transitions and the response-by-response patterns of behavior. Our results suggest that simple reinforcement learning models must account for the effects of past choices to accurately characterize behavior in this task, and that models with these properties provide a conceptual tool for studying how both past reinforcers and past choices are integrated by the neural systems that generate behavior.     

Earning and obtaining reinforcers under concurrent interval scheduling

Contingencies of reinforcement specify how reinforcers are earned and how they are obtained. Ratio contingencies specify the number of responses that earn a reinforcer, and the response satisfying the ratio requirement obtains the earned reinforcer. Simple interval schedules specify that a certain time earns a reinforcer, which is obtained by the first response after the interval. The earning of reinforcers has been overlooked, perhaps because simple schedules confound the rates of earning reinforcers with the rates of obtaining reinforcers. In concurrent variable-interval schedules, however, spending time at one alternative earns reinforcers not only at that alternative, but at the other alternative as well. Reinforcers earned for delivery at the other alternative are obtained after changing over. Thus the rates of earning reinforcers are not confounded with the rate of obtaining reinforcers, but the rates of earning reinforcers are the same at both alternatives, which masks their possibly differing effects on preference. Two experiments examined the separate effects of earning reinforcers and of obtaining reinforcers on preference by using concurrent interval schedules composed of two pairs of stay and switch schedules (MacDonall, 2000). In both experiments, the generalized matching law, which is based on rates of obtaining reinforcers, described responding only when rates of earning reinforcers were the same at each alternative. An equation that included both the ratio of the rates of obtaining reinforcers and the ratio of the rates of earning reinforcers described the results from all conditions from each experiment.     

Experiences of mandated reporting among family therapists: a qualitative analysis

Mandated reporting of child abuse by Family Therapists (FTs) has been examined by the authors in two previous studies. The first study found that mandated reporting issues negatively affected FTs abilities to maintain a systemic focus. The second study surveyed types and frequencies of negative experiences of FTs with mandated reporting. A 46-item questionnaire was administered to 101 FTs. Results were significant for four of the items. The respondents also provided 116 comments related to mandated reporting experiences. This study provides a qualitative analysis of the written comments of the respondents regarding their xexperiences with mandated reporting of child abuse.
