A precision tooth-pulp stimulation technique for the assessment of pain threshold

Accurate and consistent pain threshold measurements for the tooth pulp can be achieved with careful preparation of a moisture-proof appliance and the use of a high-quality constant-current stimulator. Using an extant dental filling as the cathode, the usual problems associated with the control of the stimulation area and locus and, consequently, current density can be overcome. Repeated measurements showing less than ±5% variation over many months can be routinely achieved on the same individual. The technique has shown a high degree of sensitivity to common analgesic agents and is potentially useful for the investigation of variations in pain threshold over extended periods of time.     

Spoilt for choice: The role of counterfactual thinking in the excess choice and reversibility paradoxes

Contrary to popular belief many choice options and the ability to reverse one's initial choice are sometimes associated with decreased chooser satisfaction. Two studies investigated the role of counterfactual thinking in explaining these paradoxes. Participants chose drawing implements from either a limited (6) or extensive (24) choice set (Study 1), or an expected reversible/non-reversible selection (Study 2). Following a drawing task, satisfaction with their chosen implement was rated under either high or low cognitive load to manipulate the availability of counterfactual alternatives. In Study 1 satisfaction was higher with limited vs. extensive choice under low load. The number of counterfactuals generated mediated this effect. Under high load the pattern was reversed. Participants in Study 2 generated more counterfactuals when reversibility was expected under low but not high load and this partially mediated the impact of expected reversibility on revealed satisfaction. Implications for theoretical understanding of these paradoxes are discussed.     

Can the 8-coil Shakti alter subjective emotional experience? A randomized, placebo-controlled study

At present, a commercially available device (the 8-coil Shakti) claims to produce weak and complex magnetic fields that alter neurobiological processes. The effects of the Shakti on emotional responses to photographs that varied on emotional valence were investigated. Participants (N = 37) were exposed to either 30 min, of magnetic fields or a sham condition and rated their emotional reactions to a set of 54 color photographs. Although participants indicated significantly different emotional responses to images with distinct emotional valences, exposure to magnetic fields did not affect these responses, nor significantly interact with image emotional valence. Although the device's "amygdala signal" had no effect on the emotive response to images in this study, additional investigations examining the effects of weak and complex magnetic fields on various aspects of perception and cognition are warranted.     

Workplace characteristics,career/vocation satisfaction,and existential well-being in Episcopal clergy

This study considers the association of workplace conditions with the well-being of individuals in a profession that is highly imbued with the sacred – ordained ministry. Data from 1202 Episcopal clergy were collected on measures of workplace conditions (meaningfulness; safety; and cognitive, emotional, and physical availability) along with well-being (career/vocation satisfaction, and spiritual well-being). Hierarchical OLS regression analyses indicated that workplace conditions were strong predictors of well-being. Men reported slightly higher career/vocation satisfaction, and gender also moderated the relationships between workplace conditions and well-being. The results suggest that perceived workplace conditions, such as meaningfulness, safety, and resource availability can have strong links with career satisfaction and existential well-being, especially in those occupations where work and spirit are intertwined.     

Interpreting the Risks of Diabetic Renal Disease: Perspectives of those Most at Risk

Fifty people with diabetes attending a 'high risk' renal clinic were interviewed about their perceptions of diabetic nephropathy and other diabetes related complications. Despite the high risks involved many patients appeared relatively unconcerned with, or even unaware of, the severity of their condition. It is argued that lack of obvious symptoms associated with nephropathy can lead to ambiguity during consultations and greater opportunity for the use of a variety of risk attenuation strategies by the patient. It is recommended that medical staff become aware of these strategies in order to understand failures in self-management in the face of complications such as nephropathy.     

When festinger fails: Prophecy and the watch tower

Within its history, the Watch Tower has often set dates for the coming of Christ's millennial reign. The ability of Jehovah's Witnesses to endure the failure of these interpretations of Biblical prophecy reveals the power of the Watch Tower to withstand what would seem to be fatal challenges to its system of belief. In what has become a classic study, the social psychologist Leon Festinger has argued that such disconfirmations of prophecy lead only to deepened conviction and increased proselytism to persuade others that the original belief was correct. Applying Festinger's hypothesis to the prophetic speculation of the Watch Tower, I argue that his model fails to recognize how complex organizations and systems of belief shape responses to disconfirmed prophecy. Indeed, the history of Jehovah's Witnesses demonstrates that organizational structure and ideology constitute crucial variables for any analysis of reaction to prophetic failure. It is the very power of the Watch Tower as a millenarian movement that allows not only the rationalization of disconfirmation but the retrospective denial of the prophecy itself.     

A case study of ‘The Good School:’ Examples of the use of Peterson’s strengths-based approach with students

This applied case study centers on two aspects of Peterson’s research as introduced into a large K-12 school in Australia: (i) creating enabling institutions and (ii) applications of character strengths. The paper describes five character strengths initiatives. Four of the strengths initiatives have been integrated into existing school experiences such as English curriculum, school sport, student leadership, and counseling. The fifth initiative involved a brand new program which introduced a Positive Education Curriculum for years?K-10. We describe these five initiatives and then explain how students at the school may experience these in a more holistic and integrated way. We hope that this article will act as a fitting tribute to the legacy of Christopher Peterson.     

Perplexities of Filiality: Confucius and Jane Addams on the Private/Public Distinction

This article compares the ways in which the classic Western philosophical division between the private and public spheres is challenged by an apparently disparate pair of thinkers—Confucius and Jane Addams. It is argued that insofar as the public and private distinction is that between the sphere of the family and that outside of the family, Confucius and Addams offer ways of rethinking that distinction. While Confucius endorses a porous relation between these realms, Addams advocates a relation that fosters reconstructive transformation of each the private and public spheres. Because Confucius and Addams both challenge the idea of a rigid separation between the private and public, while at the same time differing from one another in important ways, a comparative engagement of their views is performed, with the suggestion that Confucians might glean very much from Addams, while contemporary feminists might do the same from both she and Confucius.     

Knowledge management: A re-assessment and case

The authors are building a knowledge management system (KMS) for use by several U.S. federal agencies. Its use must harmonize with multiple agency and disciplinary cultures, and also link with the efforts of at least one international agency. In this paper, we present the KMS project’s technological contributions and implementation considerations as a case in knowledge management (KM). We link the public-sector case with our assessment of KM’s current status and future prospects. We find the challenges for KM’s future are in theory, interactivity, integration, the recognition of cultural differences, and the design of marketing programs that respect these differences. His research focuses on technology management and technology entrepreneurship. Dr. Delcambre’s research focuses on object-oriented and other database data models. developed the Metadata++ software discussed in this paper. With Lois Delcambre, he has been exploring models for terms or keywords that are used in a digital library.
