An application of the matching law to evaluate the allocation of two- and three-point shots by college basketball players

We applied the matching equation to evaluate the allocation of two- and three-point shots by male and female college basketball players from a large Division 1 university. The matching law predicts that the proportion of shots taken from three-point range should match the proportional reinforcement rate produced by such shots. Thus, we compared the proportion of three-point shots taken relative to all shots to the proportion of three-point shots scored relative to all shots scored. However, the matching equation was adjusted to account for the greater reinforcer magnitude of the three-point basket (i.e., 1.5 times greater than the two-point basket reinforcer magnitude). For players with substantial playing time, results showed that the overall distribution of two- and three-point shots was predicted by the matching equation. Game-by-game shot distribution was variable, but the cumulative proportion of shots taken from three-point range as the season progressed was predicted almost perfectly on a player-by-player basis for both male and female basketball players.

Three predictions of the economic concept of unit price in a choice context

Economic theory makes three predictions about consumption and response output in a choice situation: (a) When plotted on logarithmic coordinates, total consumption (i.e., summed across concurrent sources of reinforcement) should be a positively decelerating function, and total response output should be a bitonic function of unit price increases; (b) total consumption and response output should be determined by the value of the unit price ratio, independent of its cost and benefit components; and (c) when a reinforcer is available at the same unit price across all sources of reinforcement, consumption should be equal between these sources. These predictions were assessed in human cigarette smokers who earned cigarette puffs in a two-choice situation at a range of unit prices. In some sessions, smokers chose between different amounts of puffs, both available at identical unit prices. Individual subjects' data supported the first two predictions but failed to support the third. Instead, at low unit prices, the relatively larger reinforcer (and larger response requirement) was preferred, whereas at high unit prices, the smaller reinforcer (and smaller response requirement) was preferred. An expansion of unit price is proposed in which handling costs and the discounted value of reinforcers available according to ratio schedules are incorporated.     

The Responses of Health Systems to Marital Sexual Violence – A Perspective from Southern India

ABSTRACT

Marital sexual violence is a serious problem in India. However, marital rape and most other forms of marital sexual violence are not criminalized in the country. This qualitative study with healthcare providers (physicians and nurses), lawyers, members of a non-profit organization that offers domestic violence support services out of a hospital, a journalist and two lawyers suggest that the majority of care providers recognize that marital sexual violence is a serious concern, and agree that health systems can play a vital role in addressing both the immediate biomedical concerns of survivors, and also overall well-being. The study reveals several systemic and internal factors that hinder responsiveness of Indian health institutions. These include, the absence of a protocol or uniform internal guidelines in most hospitals, a lack of screening programs to capture the presence of violence occurring when patients visit hospitals for other reasons, a large patient load, a lack of gender sensitivity in providers’ education, an absence of domestic violence shelters, and poor interlinkages between support services such as counseling and legal services. Notwithstanding these challenges, some exemplar physicians and nurses assist survivors of sexual violence, sometimes risking their own safety. The Indian health system can be made more responsive, provided these factors are addressed, and crucially budgets are allocated for interventions.     

MUST ETHICS BE THEOLOGICAL? A CRITIQUE OF THE NEW PRAGMATISTS

In the last decade there has been a pragmatic turn in the work of those doing Christian ethics, especially as represented by the work of Jeffrey Stout and Franklin Gamwell. The pragmatic turn represents a critique of the highly influential work of Stanley Hauerwas and Alasdair MacIntyre, which argues for a strongly intra-church ethics. The pragmatists are correct in arguing that Christian ethics must engage the public sphere. However, I argue that they are deeply mistaken in their claim that this engagement must rest on a weak or non-existent theology. I show that the claim that robust theology adds nothing to ethics, and that we can get along without it, is unsustainable.     

THE UNIVERSALITY OF JEWISH ETHICS: A Rejoinder to Secularist Critics

Jewish ethics like Judaism itself has often been charged with being "particularistic," and in modernity it has been unfavorably compared with the universality of secular ethics. This charge has become acute philosophically when the comparison is made with the ethics of Kant. However, at this level, much of the ethical rejection of Jewish particularism, especially its being beholden to a God who is above the universe to whom this God prescribes moral norms and judges according to them, is also a rejection of Christian (or any other monotheistic) ethics, no matter how otherwise universal. Yet this essay argues that Jewish ethics that prescribes norms for all humans, and that is knowable by all humans, actually constitutes a wider moral universe than does Kantian ethics, because it can include non-rational human objects and even non-human objects altogether. This essay also argues that a totally egalitarian moral universe, encompassing all human relations, becomes an infinite, totalizing universe, which can easily become the ideological justification ( ratio essendi ) of a totalitarian regime.     

Confucianism and cosmopolitanism

ABSTRACT

This essay investigates the Confucian cosmopolitan aspiration. First, it examines the nature of cosmopolitanism and its distinction from universalism. It demonstrates that cosmopolitanism is a philosophical doctrine that consists of two core tenets: (1) the tenet that humankind in whole is a social-political community under the rule of law; each person has global duty and obligation; (2) the tenet that a cosmopolitan world society is one of peoples of diverse cultures that are constellated into a community under the rule of law. Secondly, it explores Confucian cosmopolitanism consisting of five tenets: (1) the vision of humankind in whole as a community; (2) the concept of one’s cosmopolitan belonging; (3) the concept of equal moral worthiness of all human beings and inviolability of human dignity; (4) the concept of cultural diversity of humanity; and (5) the aspiration to a world society of permanent peace. Thirdly, it discusses why we must have a cosmopolitan reading, not a universalistic reading, of Confucianism.     

Halakhah as Torat Hayyim: the values-conscious visions of Eliezer Berkovits and Emanuel Rackman

In the third quarter of the twentieth century, Eliezer Berkovits and Emanuel Rackman were two of the most articulate spokesmen of an approach to the interpretation and application of Jewish law, in the United States, identified with modern Orthodoxy. Each viewed their understanding of the development of Halakhah as an organic expression of the millennia-old process that is torat hayyim, living Torah. Both Berkovits and Rackman moved to Israel in the 1970s; each was, increasingly, marginalized in the world of organized Orthodoxy.

The tropes sounded by Berkovits and Rackman were remarkably consistent over their careers. One particular area that both recognized as urgently calling for halakhic development was matters relating to women. In this connection, as with other issues they addressed, they maintained that Torah principles of the ethical have a significant role to play in Jewish legal development. This essay focuses on the visions of halakhic development articulated by Berkovits and Rackman during the third quarter of the twentieth century.
