This new edition of Baran and Davis's successful text provides a comprehensive, historically based, introduction to mass communication theory. Clearly written with examples, graphics, and other materials to illustrate key theories, this edition traces the emergence of two main bodies of mass communication theory: social, behavioral and critical, cultural. The authors emphasize that media theories are human creations that typically are intended to address specific problems or issues.

Reflections about the role of human choice in determining personal health occur in the writings of practitioners and laymen throughout history. The Greek and Roman writers emphasized the effect of life's activities. During the Middle Ages and Renaisance, disease continued to be seen as a consequence of disorder of the bodily humors, which were under the individual's control. The rise of the paternalistic national regimes in Europe produced the view that society had the responsibility to maintain health. Jacksonian egalitarianism led (...) to a reaction against the agressive therapies of established professional experts, a view furthered by the Thomsonian belief that people should wrest control of their health away from orthodox physicians. Among the twentieth century reactions was the movement to urge people to have doctors evaluate laypersons' health. By the 1970s a movement emerged emphasizing again personal responsibility, which, in turn, produced a concern that this was merely "victim-blaming". Views on the role of lay people in determining personal health are heavily influenced by prevailing social, political, and moral climates. Keywords: "responsibility for health: social, personal, or professional?", "causes of illness", "self-reliant health care", historical influences, responsibility for health, "victim-blaming" CiteULike Connotea Del.icio.us What's this?

Although deconstruction has become a popular catchword, as an intellectual movement it has never entirely caught on within the university.

Frontiers of Consciousness is a study of the problem of consciousness in a historic period of revolutionary change, and an authentic example of “interdisciplinary studies.” The book contains a wealth of insight into the conceptual interrelationships between the work of the American philosophers who have been called the Builders (William James, Josiah Royce, Charles Peirce, and John Dewey) and the work of three great modernist poets (T. S. Eliot, Wallace Stevens, and William Carlos Williams).

The postmodern situation has given rise to a quest for new understandings of the relationship between theology and science. Drawing illustrative material from an episode of Star Trek: Voyager, I look at three paradigmatic answers to the questionn posed in the title—th modern empirical scientific, the renewed medieval, and the post‐modern—with the goal of outlining a methodological approach for an engagement between Christian theology and sciencein the post‐modern context. Drawing insight from post‐empirical philosophy of science and the sociology of knowledge, (...) I argue that both science and theology engage in the task of constructing a world for human habitation.

Thirty-three physicians, bioethicists, and medical economists from ten different countries met at Lawrence University, Appleton, Wisconsin, to create The Appleton Consensus: International Guidelines for Decisions to Forego Medical Treatment. The guidelines deal with four specific decision-making circumstances: 1. Five guidelines were created for decisions involving competent patients or patients who have executed an advance directive before becoming incompetent, and those guidelines fell into three categories. 2. Thirteen guidelines were created for decisions involving patients who were once competent, but are not (...) now competent, who have not executed an advance directive. 3. Seven guidelines were created for decisions involving patients who are not now and never have been competent, for whom 'no substituted judgement' can be rendered. 4. Eleven guidelines were created for decisions involving the scarcity of medical resources, which exists in all communities. Five concepts were identified as being critical in the establishment of priorities, given the reality of scarce health resources (1). The term 'physician' is used in the American sense, synonymous with 'medical practitioner'. (shrink)

Two methods of dietary recording, the 24-hr recall and the weighed dietary intake methods, are considered appropriate for estimating energy and nutrient intakes in studies of human fertility. The former method gives lower estimates than the latter, although weighed intakes may underestimate true intakes. Examination of food intakes of pregnant, lactating, and non-pregnant, non-lactating New Guinean women shows their diet to be less homogeneous than is generally assumed for groups in developing countries. As a result direct observations of food intake (...) for a limited number of days are not sufficiently accurate for the estimation of intake of most of the nutrients examined. Rather the study design should reflect the variability of intakes of the nutrients and groups under consideration. (shrink)

Coordination is a key problem for addressing goal–action gaps in many human endeavors. We define interpersonal coordination as a type of communicative action characterized by low interpersonal belief and goal conflict. Such situations are particularly well described as having collectively “intelligent”, “common good” solutions, viz., ones that almost everyone would agree constitute social improvements. Coordination is useful across the spectrum of interpersonal communication—from isolated individuals to organizational teams. Much attention has been paid to coordination in teams and organizations. In this (...) paper we focus on the looser interpersonal structures we call active support networks, and on technology that meets their needs. We describe two needfinding investigations focused on social support, which examined four application areas for improving coordination in ASNs: academic coaching, vocational training, early learning intervention, and volunteer coordination; and existing technology relevant to ASNs. We find a thus-far unmet need for personal task management software that allows smooth integration with an individual’s active support network. Based on identified needs, we then describe an open architecture for coordination that has been developed into working software. The design includes a set of capabilities we call “social prompting”, as well as templates for accomplishing multi-task goals, and an engine that controls coordination in the network. The resulting tool is currently available and in continuing development. We explain its use in ASNs with an example. Follow-up studies are underway in which the technology is being applied in existing support networks. (shrink)

Purified nuclei are being used as a test system to study the regulation of nuclear enzymes in plants. Regulatory agents such as light, hormones and polyamines can stimulate kinases or phosphatases that control nuclear protein phosphorylation and they can modulate the activity of as yet unidentified enzymes required for transcript synthesis and/or stabilization. This essay summarizes current findings and discusses the advantages and pitfalls of using isolated nuclei to investigate how nuclear functions are controlled.
