De Villiers and Herrnstein (1976) have shown that the equation for simple action, derived from the matching law, predicts change in behavioral output for some 40 experiments in which the value of a single source of reinforcement has been varied. Using only the positive-reinforcement studies they cite that used five or more different reinforcement values, we found the high percentage of variance they report accommodated by this equation (94%) is predicated on instances of averaging rates of behavioral output before making a least-squares fit of the equation. In our reanalysis, which minimizes rate averaging, only 78% of the data variance is accommodated. This diminished data-variance accommodation can be improved by adding parameters that permit the equation's scaling constant to change as a function of reinforcement. Although these parameters permit acceptable levels of accommodation of data variance, they correspond to no obvious psychological processes. These findings support the view that the equation for simple action is an inadequate model for behavioral output. 相似文献

Francisco de Vitoria and Francisco Suárez on Religious Authority and Cause for Justified War: The Centrality of Religious War in the Christian Just War Tradition 下载免费PDF全文
Melvin Endy 《The Journal of religious ethics》2018,46(2):289-331
Contrary to the received understanding that Francisco de Vitoria and Francisco Suárez ruled out religious war by grounding just cause in natural law, they supported a robust view of papal authority for war when necessary for the defense of the church against heretics, schismatics, and pagans as well as for the spread of Christianity and Christendom throughout the world. They believed that religious wars were in accord with natural law as a means to its fulfillment in Christianity, as a justification for the defense of the church as the one true faith, and as a moral obligation to provide all of humanity with the opportunity to receive Christian truth and grace. The neo‐Thomists' vigorous support for religious war was in the mainstream of the Christian just war tradition from the time of the wars against pagans in the early middle ages through their own time. This finding and the continuation into the modern era of sanctified patriotism stemming from the mixing of church and state especially during war that began in early Middle Ages, along with the historic roots of the recently prominent presumption against war, argue for a more complex understanding of the normative Christian just war tradition than that found among supporters of the classic interpretation of that tradition. 相似文献

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. 相似文献

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. 相似文献

Parents‐in‐law's topic avoidance: Understanding the role of interaction goals and relational characteristics 下载免费PDF全文
Sylvia L. Mikucki‐Enyart 《Personal Relationships》2018,25(3):433-457
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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
