Internet use in the contemporary media environment

Although a significant amount of research has focused on traditional media choice and use, and even on some ‘new’ media, these studies have either neglected the Internet and World Wide Web or were conducted prior to their recent popularity. This study offers a novel exploration of individuals' use of three Internet functions (information retrieval, information giving, and conversation capabilities) in the context of the use of other communication media. Data from 684 individuals demonstrate that the Internet is a multidimensional technology used in a manner similar to other, more traditional media. Specifically, conversation features of the Internet align with mediated interpersonal technologies (the telephone and electronic mail), whereas the Internet's information‐retrieval and information‐giving features are used in ways similar to mass media channels (newspapers, television, and books and magazines). In addition, needs fulfilled by these channels cluster in ways consistent with past research, regardless of the technologies employed to meet them.     

Thinking About Gender

I present a way of thinking about gender that I have found helpful in evaluating various proposed feminist projects. By considering gender and value as independent dimensions, relationships of “difference” can be more clearly perceived as involving relationships of lack, of complementarity, or of perversion. I illustrate the use of my gender/value “compass” with applications to questions of self-identity, rationality, and knowledge. This way of thinking about gender allows a conceptualization of feminism that neither erases nor emphasizes gender distinctions.     

Neonatal imitation of tongue protrusion and mouth opening: Methodological aspects and evidence of early individual differences

The present work examines imitation of mouth opening and tongue protrusion in 32 full-term infants at three different occasions: When the infants are two to three days, three weeks, and three months old. The analysis focuses (1) on individual differences in imitative behaviour and (2) on how to operationalize the infants' responses. The overall group analysis revealed that imitation of tongue protrusion was statistically significant for both two- to three-day-old and three-week-old infants but not when the children had become three months old. No statistically significant effect was observed for imitation of mouth opening. Two different imitation indexes were constructed in order to assess individual differences in early imitative behaviour. Results show that short-term stability in imitative tendencies exists between the first and second observation. The results further reveal that methodological factors must be seriously considered when studying neonatal imitation: the overall imitation found for tongue protrusion is demonstrated to be dependent on how the infants' responses are coded.     

Spiritual and Ethical Beliefs of Humanists in the Counseling Profession

Considerable controversy has been waged over the spiritual and ethical beliefs of humanism. A survey of humanist counselors was conducted on selected spiritual and ethical beliefs. The results showed that ethical/spiritual pluralism best characterized the humanists' stance. The findings are discussed within the context of historical and contemporary schools of humanism.     

In Vivo Hippocampal Acetylcholine Release During Exposure to Acute Stress

Hippocampal extracellular acetylcholine (ACh) and choline levels were evaluated using in vivo microdialysis in male Fischer 344 rats before, during, and following an 80-min exposure to two different stress conditions. Measurements were taken in rats restrained and immersed in a water bath containing either 37 degreesC (normothermic-restraint) or 20 degreesC (cold-restraint) water. Results were compared to normothermic-freely-moving rats. Cold-restrained rats displayed decreased ACh levels during cold exposure relative to both normothermic-restrained and normothermic-freely-moving rats. By the end of the cold exposure period and following removal from cold, ACh levels had returned to near-baseline values. Normothermic-restrained rats had levels similar to those of normothermic-freely-moving rats, except for a marked increase in ACh following removal from restraint. Cold-restrained rats displayed a gradual elevation in choline levels during cold stress, followed by a gradual decline after stress termination, whereas both normothermic-restrained and normothermic-freely-moving rats displayed gradual decreases during the microdialysis session. These findings demonstrate that central cholinergic neurotransmission can be altered by the application of, and removal from, acute stressors. In addition, the results suggest a possible relationship between the magnitudes of both the stressor and its cholinergic consequences.     

"EVERYMAN'S ONTOLOGICAL ARGUMENT": A DISSIDENT VERSION

We must agree, I think, with Frank Ebersole that there is something preposterous in supposing that the God of religious belief, the God who handed down tablets to Moses on Mt. Sinai, etc., should be proven to exist by the ontological argument. Indeed, when we place the one, the ontological argument, by the side of the other, the God of religious belief, there seems hardly to be any connection between them. But if we agree to this perception of things, what sense can we make of the ontological argument, for example, the “pull” that it sometimes exerts on us?     

ALZHEIMER'S DISEASE AND SOCIALLY EXTENDED MENTATION

Abstract: The leading accounts of the ethics of proxy decision making implicitly draw on internalist conceptions of the philosophy of mind, or so this essay tries to demonstrate. Using the views of Ronald Dworkin as its jumping-off point, the essay argues that accepting the sort of externalism associated with writers such as Putnam and Burge would alter Dworkin's conclusions concerning how we should respond to the current or precedent decisions of people suffering from dementia. Building on the views of Agnieszka Jawarska, it argues that accepting "active" externalism à la Clark and Chambers would provide currently competent people with new resources for establishing the authority of their present values over inconsistent values they might come to entertain should they become demented.     

INQUIRY, CONVERSATION AND THEISTIC BELIEF: WILLIAM JAMES AND RICHARD RORTY GET RELIGION

This essay examines William James' view that pragmatic philosophy allows for theistic belief and compares it to Richard Rorty's argument that theistic belief is fundamentally incompatible with pragmatic philosophy. Theism is permissible for James because it is commensurate with his view of philosophy as inquiry . Theism is impermissible for Rorty because it incommensurate with his view of philosophy as conversation . James' arguments are shown to be too generic in their conception of the God in whom theistic belief may be placed, and Rorty's arguments against the desirability of theistic belief are shown to run afoul of his own philosophical program.     

Clamped Corticosterone (B) Reveals the Effect of Endogenous B on Both Facilitated Responsivity to Acute Restraint and Metabolic Responses to Chronic Stress

To determine the effects of both corticosterone (B) and chronic stressors on acute ACTH responses to restraint, young male rats were exposed to streptozotocin-induced diabetes, cold (5-7 degreesC) or intracerebroventricular (icv) neuropeptide Y (NPY) for 5 d and then exposed to restraint within 2 h after lights on. Two groups of rats were studied: intact and adrenalectomized replaced with B pellets that maintained plasma B in the normal mean 24-h range of intact rats. In addition to ACTH and B responses to restraint on d 5, body weight, food intake, fat depots, glucose and other hormones were measured to determine the role of stress-induced elevations in B on energy balance. ACTH responses to restraint were normal in intact rats subjected to diabetes or cold. By contrast, there was no ACTH or B response to restraint in NPY-infused intact rats. All 3 groups of chronically stimulated adrenalectomized rats with clamped B had facilitated ACTH responses to restraint compared to their treatment controls. Overall food intake increased in all groups of stressed rats; however, augmented intake occurred only during the light in intact rats and equally in the light and dark in B-clamped rats. White adipose depot weights were decreased by both diabetes and cold and increased by NPY in intact rats; the decreases with cold and increases with NPY were both blunted and changes in fat stores were not significant in adrenalectomized, B-clamped rats. We conclude that: 1. diabetes- and cold-induced facilitation of restraint-induced afferent input to hypothalamic control of the hypothalamo-pituitary-adrenal (HPA) axis is opposed in intact rats by the elevated feedback signal of B secretion; 2. NPY does not induce facilitation of afferent stress pathways; 3. chronic stimulation of the HPA axis induces acute hyperresponsiveness of hypothalamic neurons to restraint provided that the afferent input of this acute stimulus is not prevented by B feedback; 4. stimulus-induced elevations in B secretion result in day-time feeding; 5. insensitivity of both caloric efficiency and white fat stores to chronic stress in adrenalectomized, B-clamped rats results from loss of normally variable B levels.
