Exploring the route choice decision-making process: A comparison of planned and observed routes obtained using person-based GPS

Trip decisions are complex and involve choosing the activity destination, mode and subsequently the route for travel. This paper presents detailed information on the planned and observed route choices for the home-to-work commute. Specifically, the study examines how people formulate their route plans and describe their attitudes and preferences for their selected routes. A geographic information system (GIS) records the planned route information with the route planning sequence. Observing route choice is a difficult procedure; however, through the use of the global positioning system (GPS), one can accurately record route choice. An automated activity–trip detection algorithm processes GPS data and displays results within an internet-based prompted recall diary. The diary is used to verify trip start and end times. This combination of GPS, GIS and diary responses provides great insight into the route choice decision-making process. Thirty-one individuals from Ontario, Canada participated in answering survey questions and the collection of person-based GPS data. Results indicate a preference to minimize travel time as stated by participants in deciding what route to travel. Participants also affirmed a desire to minimize the number of stop lights/signs, as well as, avoid congestion and maximize route directness. A comparison between planned and observed routes, reveals about one-fifth of participants deviated from their planned route. This study demonstrates the need for qualitative and quantitative survey methods for exploring planned and observed route choice.     

Subjective Wellbeing on the Tibetan Plateau: An Exploratory Investigation

While working on a project to build a school for Tibetan nomad children in a remote part of the Tibetan plateau, the author carried out the first empirical exploration of personal wellbeing with a small (n = 102) sample of ethnic Tibetans. Using the PWI survey instrument, significant age, gender, and education differences with respect to satisfaction with life were revealed. In addition, the magnitude of overall satisfaction with life was found to be more consistent with Western rather than Asian populations and, future security, standard of living, gender and age were identified as the strongest predictors of life satisfaction. This paper reports on the findings drawing on the literature, Buddhist philosophy and the author’s observations for explanation.     

Improving condom use intentions and behavior by changing perceived partner norms: an evaluation of condom promotion videos for college students.

OBJECTIVE: To examine the effectiveness of 2 condom promotion videotapes on self-efficacy, intentions, and behavior. DESIGN: Two hundred twenty college students completed social-cognitive and behavioral measures and were then randomly assigned to receive one of two 30-min condom promotion videotapes (male or female student presenters) or to a wait-list control condition. Participants who watched 1 of the videotapes completed immediate posttest measures, and 85% of participants completed a 4-month follow-up. MAIN OUTCOME MEASURES: Self-efficacy for condom use, intentions to use condoms, use of condom during last sex, and consistent condom use over the last month. RESULTS: Participants who received either video reported greater self-efficacy to refuse to have unprotected sex and intentions than controls at follow-up. Individuals who received either video were more likely than controls to report using a condom during last sex with a regular partner, and those who watched the female presenter were more likely to report consistent condom use. CONCLUSION: Participants benefited in terms of self-efficacy and intentions from receiving either video, but both men and women benefited more in terms of condom use behavior from receiving the female video. Future research is needed to determine whether opposite-sex speaker videos could be beneficial with a larger (and more sexually active) sample and whether these effects are maintained over time.     

The Occurrence of Bullying in Global Organizations: A Model and Issues Associated With Social/Emotional Contagion

Workplace bullying in global organizations occurs for several reasons, including growing diversity, increased dispersion of employees in geographic locations, lack of experience of managers with new environments, and varying requirements. To gain insight into the bullying phenomenon, one must examine the characteristics of the bully, the target of bullying activities (e.g., the victim or the bullied), observers of the bullying (e.g., bystanders), and resulting changes in the organizational culture because of the bullying. One additional element to be assessed is the means by which bullying activities are embodied in an organization's culture (i.e., social/emotional contagion). This paper proposes a model of bullying in global organizations and examines the potential of social/emotional contagion developing in global organizations' cultures.     

EEG mu rhythm and imitation impairments in individuals with autism spectrum disorder

Imitation ability has consistently been shown to be impaired in individuals with autism. A dysfunctional execution/observation matching system has been proposed to account for this impairment. The EEG mu rhythm is believed to reflect an underlying execution/observation matching system. This study investigated evidence of differential mu rhythm attenuation during the observation, execution, and imitation of movements and examined its relation to behaviorally assessed imitation abilities. Fourteen high-functioning adults with autism spectrum disorder (ASD) and 15 IQ- and age-matched typical adults participated. On the behavioral imitation task, adults with ASD demonstrated significantly poorer performance compared to typical adults in all domains of imitation ability. On the EEG task, both groups demonstrated significant attenuation of the mu rhythm when executing an action. However, when observing movement, the individuals with ASD showed significantly reduced attenuation of the mu wave. Behaviorally assessed imitation skills were correlated with degree of mu wave attenuation during observation of movement. These findings suggest that there is execution/observation matching system dysfunction in individuals with autism and that this matching system is related to degree of impairment in imitation abilities.     

Who is susceptible to conjunction fallacies in category-based induction?

Recent evidence suggests that the conjunction fallacy observed in people’s probabilistic reasoning is also to be found in their evaluations of inductive argument strength. We presented 130 participants with materials likely to produce a conjunction fallacy either by virtue of a shared categorical or a causal relationship between the categories in the argument. We also took a measure of participants’ cognitive ability. We observed conjunction fallacies overall with both sets of materials but found an association with ability for the categorical materials only. Our results have implications for accounts of individual differences in reasoning, for the relevance theory of induction, and for the recent claim that causal knowledge is important in inductive reasoning.     

Facial dynamics as indicators of trustworthiness and cooperative behavior

Detecting cooperative partners in situations that have financial stakes is crucial to successful social exchange. The authors tested whether humans are sensitive to subtle facial dynamics of counterparts when deciding whether to trust and cooperate. Participants played a 2-person trust game before which the facial dynamics of the other player were manipulated using brief (<6 s) but highly realistic facial animations. Results showed that facial dynamics significantly influenced participants' (a) choice of with whom to play the game and (b) decisions to cooperate. It was also found that inferences about the other player's trustworthiness mediated these effects of facial dynamics on cooperative behavior.
