On Christensen's conjecture

In this paper we give solution to a conjecture appearing in Christensen (1997, p. 360) in relation to the definitions of standardized residuals in loglinear models.

Perspectives on Regional and Enterprise Marginality: Dairying in Michigan's North Country1

Abstract Dairy farmers in Michigan's Upper Peninsula, an economically marginal rural region, are encumbered by contextual constraints that are not similarly faced by their downstate counterparts. However, this does not mean that they are any less ambitious or less efficient in dealing with the resources available to them. Indeed, dairying and similar small-scale economic enterprises in this and other marginal contexts may be quite competitive and sustainable if appropriate sociopolitical supports are instituted and, in the case of dairying, if marketing orders and regulatory policies are formulated and implemented in light of their impact upon the economic growth and viability of the wider region. To explore this issue, we consider the situations, basic characteristics, and restructuring trends over time of dairy farms in three upstate localities as compared with that of a downstate dairy farming community.     

Nonverbal expectancy violations and conversational involvement

A central feature of nonverbal expectancy violations theory is that unexpected behaviors trigger a cognitive-affective appraisal of such behavior, leading to a valencing of the behavior(s) as positive or negative. It has been proposed that communicator reward mediates the interpretation and evaluation of such violations but may be more important when the violative act is ambiguous in meaning than when it is not. Unclear is whether nonverbal behavioral composites introduce greater or less equivocality of interpretation. Two experiments employing multi-cue conversational involvement violations addressed this issue. In the first, dyads (N=51) engaged in a 10-minute baseline interview, after which participants rated each other on several measures of reward valence. One randomly selected member then served as a confederate interviewee during a second interview and either significantly increased or decreased involvement. In the second experiment, reward was manipulated as physical attractiveness, status, and task expertise. Dyads (N = 60) engaged in prolonged problem-solving discussions during which the confederates either committed an involvement violation or not. In both experiments, the involvement changes were sufficiently unexpected, arousing, and distracting to qualify as violations of expectations. Analysis of message interpretations indicated that (1) relative to normal involvement levels, increased nonverbal involvement was interpreted as most immediate/affectionate, receptive, similar, dominant, and composed, and decreased involvement as least so, and (2) reward mediated only the interpretation of formality. High involvement violations in turn produced greater attraction, credibility, and persuasiveness than low involvement violations for high as well as low-reward communicators, as predicted.where Joe Walther and Jim Baesler are doctoral students. An earlier version of this paper was presented to the annual meeting of the International Communication Association, New Orleans, May 1988.     

Invasion. A hospital in transition following the 1983 Grenadian intervention

Stress, confusion, and a sense of loss were inevitable during the hospital relocation, especially given the large number of clients, ward communities, and staff needed to move and adjust to change. Despite the fact that the change was perceived as a positive and progressive step in psychiatric-mental health care in Grenada, there were many obstacles and much resistance to overcome. As expected, staff's and clients' fears centered around themes of impending loss and abandonment. An understanding of the transition process, along with the availability of experienced hospital staff for support and guidance, greatly aided the relocation process. Relocation still presented problems and Mt. Gay Hospital continues to struggle to carry out the lasting and beneficial changes that will best promote a therapeutic and culturally sensitive client/staff environment. Despite the fact that the hospital relocation was not entirely self-determined, but partially imposed by political circumstances, a positive resolution of the crisis occurred. The crisis brought about the change that, in this circumstance, is seen as synonymous with growth. It acted as a catalyst to bring about help from unexpected and much needed sources (U.S.A.I.D./Project Hope), which may not have otherwise been available to facilitate such a change. Richmond Hill Mental Hospital took control and advantage of a crisis situation and made it serve its immediate and pressing need for a new psychiatric hospital.
