Studying verbal interaction on the Internet: The case of rumor transmission research

This paper describes the advantages of computer-mediated communication networks (Internet, Bitnet, and Usenet) in the study of verbal interaction. Research involving observation and analysis of rumor transmission patterns is presented as an illustration. Issues related to the generalizability of findings and the ethics of observational research are also briefly discussed.     

A simulated annealing methodology for clusterwise linear regression

In many regression applications, users are often faced with difficulties due to nonlinear relationships, heterogeneous subjects, or time series which are best represented by splines. In such applications, two or more regression functions are often necessary to best summarize the underlying structure of the data. Unfortunately, in most cases, it is not known a priori which subset of observations should be approximated with which specific regression function. This paper presents a methodology which simultaneously clusters observations into a preset number of groups and estimates the corresponding regression functions' coefficients, all to optimize a common objective function. We describe the problem and discuss related procedures. A new simulated annealing-based methodology is described as well as program options to accommodate overlapping or nonoverlapping clustering, replications per subject, univariate or multivariate dependent variables, and constraints imposed on cluster membership. Extensive Monte Carlo analyses are reported which investigate the overall performance of the methodology. A consumer psychology application is provided concerning a conjoint analysis investigation of consumer satisfaction determinants. Finally, other applications and extensions of the methodology are discussed.     

The Scientific Study of Religion: Its Contribution to the Study of the Bhagavadgītā

Abstract. The Bhagavadg?tā is a popular Hindu text containing eighteen chapters. It begins with the hero, Arjuna, showing a marked unwillingness to engage in combat on the eve of battle. He is finally persuaded to do so by Krishna, who is an incarnation of God. Krishna actually reveals himself as such to an amazed Arjuna in the eleventh chapter. The fact that Arjuna does not immediately heed Krishna's advice to engage in battle after Krishna's sensational self‐disclosure has long puzzled students of the text. It is only at the end of the eighteenth chapter that Arjuna finally shows his readiness to fight. In this essay I argue that the discussion of the nine primary sensory states by Eugene d'Aquili may help resolve this issue and thus provide an instance of a case in which modern scientific study of religion enhances our understanding of a religious phenomenon, as a corrective to the usual charge that it must invariably diminish it.     

Exhaled breath analysis in evaluation of psychological stress: A short literature review

Physiological stress is pervasive in today's society. Its detection is normally performed through several unobtrusive methods, driving both caregivers and patients to take measures to reduce the burden of this condition on human health. Among the methods for assessing stress, exhaled breath analysis represents a non‐invasive, real‐time alternative to classic laboratory tests. Therefore, a literature review was performed to assess the presence of altered parameters, related to psychological stress, in exhaled breath. Most studies in our review measured nitric oxide (NO), whose concentration was often correlated, either positively or negatively, with psychological stress, with reasonable scientific support. Other compounds (isoprene, terpene and so on) were rarely studied and with mixed evidence. Further investigations are needed to elucidate the involvement and the pathophysiological role of NO in stress, possibly including a greater number of individuals, as sample size actually represents the main limitation of the work published to date.     

When social psychology became less social: Prasad and the history of rumor research

Rumor research, in general, and its delayed incorporation of the work of rumor researcher Jamuna Prasad, in particular, exemplify how the intellectual climate of American social psychology discouraged the development of social approaches. In the present paper, we explain his conceptualization of how rumors start and spread, and explore findings from subsequent research supporting or negating his propositions. It is our contention that, although Prasad had identified the basic variables involved in rumor generation and transmission correctly, mainstream social psychological research in the 1940s did not incorporate his contributions. Instead, mirroring the Zeitgeist of American social psychology, rumor research was approached from a predominantly individual level of analysis. In the present paper, the authors have tried to resurrect some of the group-level variables from Prasad's treatment of rumor and to suggest that social psychology adopt a more 'social' approach to rumor.     

The Purusārthas: An Axiological Exploration of Hinduism

Three doctrines have often been identified in the context of Hindu civilization as its distinctive markers: the doctrine of the varnas (or the doctrine of the four classes), the doctrine of asramas (or the doctrine of the four stages of life), and the doctrine of the purusarthas (or the doctrine of the four goals of life). The study of the last of these has been comparatively neglected and the doctrine has even been dubbed a myth (Krishna 1996, 189–205). The purpose of this article is twofold: to establish the cogency of the doctrine of the purusarthas in the face of such criticism and to indicate the directions in which the doctrine could be developed further.     

Assessing alternative models of individualism and collectivism: a confirmatory factor analysis

Six alternative structural models of individualism–collectivism are reviewed and empirically compared in a confirmatory factor analysis of questionnaire data from an Australian student sample (N = 340). Central to the debate about the structure of this broad social attitude are the issues of (1) polarity (are individualism and collectivism bipolar opposites, or orthogonal factors?) and (2) dimensionality (are individualism and collectivism themselves higher‐order constructs subsuming several more specific factors and, if so, what are they?). The data from this Australian sample support a model that represents individualism and collectivism as a higher‐order bipolar factor hierarchically subsuming several bipolar reference‐group‐specific individualisms and collectivisms.

Validation of the Career Adapt-Abilities Scale and an examination of a model of career adaptation in the Philippine context

This paper presents the validation of the Career Adapt-Abilities Scale (CAAS) in the Philippine context. The CAAS consists of four subscales, with six items each, measuring self-regulative psychosocial resources (e.g., concern, curiosity, control, and confidence) for coping with occupational tasks and transitions. Filipino university students (N = 289) and working adults (N = 495) participated in the study. Internal consistency estimates for the full scale and subscales ranged from .87 to .97. Confirmatory factor analyses supported the multidimensional and hierarchical model of career adaptability. The factor structure was similar to that obtained from the CAAS international validation from 18 countries. Results also suggested that career adaptability was positively associated with adaptivity in the form of tenacious goal pursuit and flexible goal adjustment as well as with adaptation outcomes of career satisfaction and promotability. Overall, the findings confirm the utility of CAAS in the Philippine context and support the model that states higher levels of personal adaptivity (willingness) and career adaptability (competence) relate to better adaptation outcomes in terms of career success.
