Scaling Incentives: Determining Preference and Indifference in 8- to lO-Year-Old Girls

The present study adopted procedures similar to those used by Logan (1965) to determine choice behavior in children. The objective was to provide an improved methodology in delay-of-gratification studies, thus avoiding the problems associated with scaling different kinds of rewards, and to provide approximate functions relating a delay-of-token reward to choice behavior. Thus, 7 girls aged 8 to 10 years were exposed to a choice paradigm in which a larger reward (2 tokens) was pitted against a smaller reward (1 token); access to these rewards was delayed a certain period of time. The results of this experiment showed that as the delay of the larger reward increased, preference for the smaller reward increased in an orderly fashion. The finding that delay shifted preference from the larger to the smaller reward is discussed in relation to current theory. The results of this experiment also provide evidence for the utility of tokens in scaling incentives for choice studies.     

Functional magnetic resonance imaging study of Piaget's conservation-of-number task in preschool and school-age children: a neo-Piagetian approach

Jean Piaget’s theory is a central reference point in the study of logico-mathematical development in children. One of the most famous Piagetian tasks is number conservation. Failures and successes in this task reveal two fundamental stages in children’s thinking and judgment, shifting at approximately 7 years of age from visuospatial intuition to number conservation. In the current study, preschool children (nonconservers, 5-6 years of age) and school-age children (conservers, 9-10 years of age) were presented with Piaget’s conservation-of-number task and monitored by functional magnetic resonance imaging (fMRI). The cognitive change allowing children to access conservation was shown to be related to the neural contribution of a bilateral parietofrontal network involved in numerical and executive functions. These fMRI results highlight how the behavioral and cognitive stages Piaget formulated during the 20th century manifest in the brain with age.     

RACE DIFFERENCES IN TERMINATION AT WORK: THE ROLE OF EDUCATIONAL INEQUALITY

Prior research has demonstrated that race, at least to some extent, is related to employment decisions such as selection and performance appraisals. However, little prior research has addressed the impact of race on employment termination. The current study investigates whether race is related to employment termination and highlights the importance of education, an important component of human capital, in understanding racial differences in termination. Results based on 548 employees from a large hotel chain indicate that race is related to termination; however, race is not predictive of termination when education is included in the regression analysis as a predictor. These findings support the notion that a societal level variable (i.e., education) is an important factor in reducing racial inequality in employment practices.     

Swimming and Speaking Spanish

The dominant view of the status of knowledge of language is that it is theoretical or what Gilbert Ryle called knowledge-that. Defenders of this thesis may differ among themselves over the precise nature of the knowledge which underlies language, as for example, Michael Dummett and Noam Chomsky differ over the issue of unconscious knowledge; however, they all agree that acquisition, understanding and use of language require that the speaker have access to a theory of language. In this paper, I argue that this view is mistaken. Knowledge of language is properly seen as practical knowledge, knowledge-how. My target is Michael Dummett’s treatment of theory of meaning in The Seas of Language. If my argument goes through, underlying assumptions about the nature of cognition as computational must be adjusted to allow for other forms of knowledge, which are arguably more basic, and which underlie knowledge-that.     

HR practices as a mediator between organizational culture and transformational leadership: Implications for employee performance

Studies pertaining to human resource (HR) management in India have revealed a variety of factors that significantly affect employee performance not the least of which are organizational culture and leadership issues. The present study posits firm level HR practices as a mediator between organizational culture and transformational leadership whose outcomes are hypothesized as lower levels of individual employees’ intention to quit the organization and higher level of performance. For this purpose, data were collected from mangers/executives (N=357) and subjected to multivariate analysis. The results reveal that culture and leadership are significant predictors of intention to quit and employee performance. The results also show that HR practices are important mediators in transmitting the influence of the predictor variables to the criterion variables.     

Effectiveness of a Hearing Conservation and Vocal Hygiene Program for Kindergarten Children

Abstract

Noise-induced hearing loss and disorders of the voice are two potentially preventable communication disorders. This study sought to determine if young children's knowledge regarding potentially abusive hearing and voice behaviors can be changed through education. An interactive educational program-“Ears for Listening, Voice for Speaking” (ELVS)-was presented to 66 kindergarten students. A questionnaire, testing the students' knowledge regarding anatomy, abusive behaviors, and conservation practices, was administered pre- and post-ELVS participation. A statistically significant increase was found in the students' knowledge post-ELVS participation. Scores on the voice questions were lower than hearing, and, although the difference was not statistically significant, girls scored higher than boys, both pre- and post-ELVS participation. This study highlights the importance of early intervention through education in preventing noise-induced hearing loss and voice disorders.     

Churches as organisations: towards a virtue ecclesiology for today

This article is an attempt to offer insights from organisation studies to ecclesiology. To do so it draws particularly on the work of the moral philosopher Alasdair MacIntyre to offer a virtue ecclesiology for today. The application of MacIntyre's conceptual framework of practices, institutions, goods and virtues to all kinds of organisations, which already exists in the field of organisation studies, is extended to the church as an organisation. It suggests that the church may be re-described as an organisation in which the practices of faith are housed within the institution of the church. On this understanding, the gift of the church to the world is not simply the practices of faith but the manner in which they are institutionalised.     

The parental attitude research instrument: An approach to use of attitude questionnaires

Parental attitude questionnaires such as the Parental Attitude Research Instrument (PARI) are still in use despite their inherent difficulties. In light of the need to test theoretical models by measuring a range of parental characteristics, the properties of the PARI were re-examined and, on the basis of a factor analysis of the 23 subtests of the PARI, a shortened version was constructed. A measure of maternal Authoritarian Control, which was found to be associated with measures of maternal mental ability, personality, level of education, reading age, number of adverse family conditions and child-rearing practices, has proved useful for other projects related to this ongoing study. It is recommended that such instruments be used only in conjunction with other measures which examine the family environment, for example in an index of child-rearing practices.     

Caring for Nature: From Fact to Value, from Respect to Reverence

Abstract. Despite the classical prohibition of moving from fact to value, encounter with the biodiversity and plenitude of being in evolutionary natural history moves us to respect life, even to reverence it. Darwinian accounts are value‐laden and necessary for understanding life at the same time that Darwinian theory fails to provide sufficient cause for the historically developing diversity and increasing complexity on Earth. Earth is a providing ground; matter and energy on Earth support life, but distinctive to life is information coded in the genetic molecules that superintends this matter‐energy. Life is generated and regenerated in struggle, persists in its perishing. Such life is also a gift; nature is grace. Biologists and theologians join in celebrating and conserving the genesis on Earth, awed in their encounter with this creativity that characterizes our home planet.     

Lick-trading by rats: on the substitutability of dry, water, and saccharin tubes.

Thirsty rats licked two metal tubes: a water tube paired with another water tube, with saccharin, or with a dry tube. For each pair, a multipoint baseline function was measured by offering free access to one tube throughout each session, and free or restricted access to the other. The three resulting baseline functions showed the members of each pair to be mutual substitutes: When access to either tube was restricted, the rats made more licks at the other. A linear function identified the two water tubes as perfect substitutes. Convex functions identified the members of the saccharin-water and the dry-water pair as imperfect substitutes. Each pair was also tested under several reciprocal fixed-ratio schedules that required instrumental licking of either tube for contingent access to the other. The resulting schedule functions showed the members of each pair to be perfect substitutes: Water licks decreased linearly as licks at the other water tube, the saccharin, or the dry tube increased, in agreement with a conservation model of instrumental performance. Baseline and schedule functions, indistinguishable in the water-water pair, indicated a schedule facilitation of dry-tube licking in the dry-water pair and of water-tube licking in the saccharin-water pair.
