Is a picture worth a thousand words? The flexible nature of modality dominance in young children

When presented simultaneously with equally discriminable, but unfamiliar, visual and auditory stimuli, 4-year-olds exhibited auditory dominance, processing only auditory information (Sloutsky & Napolitano, 2003). The current study examined factors underlying auditory dominance. In 6 experiments, 4-year-olds (N=181) were presented with auditory and visual compounds in which (a) the complexity and familiarity of stimuli were systematically varied (Experiments 1-5) and (b) participants were explicitly instructed to attend to a particular modality (Experiment 6). Results indicate that auditory dominance is a special case of flexible modality dominance, which may stem from automatic pulls on attention. Theoretical implications of these results for understanding the development of attention and cross-modal processing, as well as linguistic and conceptual development, are discussed.     

Ex Corde Ecclesiae and American Catholic Higher Education: The Calm Before the Storm or Dead in the Water?

Amid the struggle that Catholic colleges and universities, especially those in the United States, face as they seek to preserve their religious identities, Rome formally entered the fray on August 15, 1990, when Pope John Paul II promulgated the Ex Corde Ecclesiae (Ex Corde) (literally, “from the heart of the Church”). John Paul II wrote Ex Corde in an attempt to reinvigorate the debate over how Catholic colleges and universities can remain true to their religious missions while being viable institutions of higher learning wherein faculty members are free to work as researchers and teachers who can meet the same objective performance evaluation criteria as their professional colleagues in the world of academics. In reviewing the status of Ex Corde over the more than 5 years that expired since the controversy over the adoption of The Application and The Guidelines designed to implement Ex Corde began, this article is divided into three parts. The first part reviews the basic elements of Ex Corde while the second examines both the events surrounding the adoption of The Application and The Guidelines along with their subsequent (non)implementation in the United States. The third part of the article reflects on the current status of Ex Corde in American Catholic colleges and universities, revealing that its critics have little to fear for academic freedom and/or job safety unless its terms are expressly included in employment contracts—a prospect that is not even remotely on the horizon.     

Preparing our Societies for the Multimedia Environment

The Ukrainian Society, after introducing the computer literacy course for secondary schools in 1986, is trying to reach the next stage of digital literacy through the development of a National Informatization Programme. Some results of the programme are described: the incorporation of telematics into the educational system and Internet literacy for teachers and students, free of charge and in local languages; the development of regional and local nodes of educational institutions and their incorporation into a national network; the participation of non-governmental organizations in the financing of educational programmes; and the development of a national ethics Net-Codex. Ukraine, as a typical “country in transition”, needs international support in digital literacy through co-operative projects; some proposals for such co-operation are given.     

Validation of the Attitude-Older Adult and Aging-Visual Analogue Scales (At-O-A)

ABSTRACT

Occupational therapy programs have been developed in order to promote health in older adults. However, no published studies have yet been identified for the Spanish population. This study explores the benefits of an occupational therapy health promotion program called EnvejeHaciendo (AgeDoing). The study was conducted with 15 elderly Spanish adults, examining health perception and meaningful occupational participation using the Model of Human Occupation, as well as the pedagogical methodology See, Judge, Act. The results showed an increase in the perception of health with reference to social functioning and the number of roles in which the participants wanted to get involved in the future. The participants changed their own negative perception of elderly people, they adapted to the changes provoked by aging, and they got involved in meaningful activities such as physical exercise or social activities. This program allowed participants to engage in meaningful occupations with other people and to increase perceived health status through raising awareness of difficulties.     

To have or to be? The interplay between knowledge structure and market identity in knowledge-based alliance formation

We explore how a firm’s knowledge structure characteristics and market identity—as reflected in its position in the industry value chain and market status—influence knowledge-based alliance (KBA) formation. We propose that a firm’s propensity to form KBAs is affected by the congruence (or misalignment) between its knowledge structure characteristics (i.e., knowledge depth and scope) and the role it plays in the industry, as demanded by its position in the value chain. We further argue that while a firm’s market status can amplify the positive effect of the congruence, thereby enhancing a firm’s proclivity to form KBAs, being prominent can also hurt a firm when it faces a misalignment between its knowledge structure characteristics and externally induced expectations related to its value chain position. We validate our arguments using panel data on 1051 firm-year observations for 197 firms patenting in the global fuel cell industry for the period 1999–2009. By developing a richer understanding of the relationship between a firm’s knowledge-based resources and KBA formation, we answer the call for a better understanding of how and when firms can leverage their internal knowledge configurations to improve their proclivity to form alliances.     

Integrating problem- and project-based learning opportunities: assessing outcomes of a field course in environment and sustainability

Improving student competencies to address sustainability challenges has been a subject of significant debate in higher education. Problem- and project-based learning have been widely celebrated as course models that support the development of sustainability competencies. This paper describes a course developed for a professional Master’s program in environment and sustainability that employs such a model. Additionally, the course was designed to offer value-added opportunities by introducing attributes of interdisciplinary training, service learning, academic research, and professional practice. Results from the course assessments by students, faculty, community clients and organizational partners show this model provided a range of learning, professional and practical outcomes for course partners. The value-added benefits include strengthening sustainability competencies and professional skills for students; longitudinal research opportunities for teaching faculty; real-time assessments of farming practices for community clients; and a heightened regional profile for the non-profit biosphere reserve organization supporting course delivery.     

Temporal discounting of aversive consequences in rats

Previous research has extensively evaluated the impact of delay on the value of positive reinforcers, but the study of its impact on the value of aversive consequences is scarce. The present study employed a modification of Evenden and Ryan’s procedure (1996, Psychopharmacology, 128(2), 161–170) to obtain data on temporal discounting of an aversive consequence, with rats as experimental subjects. In the first phase of the procedure, rats chose between one-pellet and four-pellet alternatives; when subjects developed preference for the larger-amount alternative, a shock was added to it, resulting in a loss of preference. In the first experimental condition, the delay to shock was progressively increased within each session from zero to 40 s (ascending delays), which resulted in a recovery of the preference for the larger-amount + shock alternative as the delay to shock was increased. In a subsequent condition (descending delays) the delay to shock was progressively decreased within each session, from 40 to 0 s. In both conditions, the preference for the smaller-amount no-shock alternative was well described by a hyperbolic function. The order of presentation of the delays within the session, ascending or descending, did not alter the relationship between preference and delay to shock. The temporal discounting curve obtained in the present study could represent a baseline for analyzing the impact that diverse environmental and pharmacological variables have on the temporal discounting of aversive consequences.
