Travel behavior changes and responses to advanced traveler information in prolonged and large-scale network disruptions: A case study of west LRT line construction in the city of Calgary

The objective of this study was the investigation of travel behavioral effects of the reduction in traffic capacity resulting from the construction of the West LRT (Light Rail Transit) line in the city of Calgary, Alberta, Canada. Travelers’ responses to real-time information providing traffic updates and advisory detours due to lane/road closures were also examined. The West LRT alignment extends approximately 8.2 km from downtown into the city’s southwest. Many road closures took place in the vicinity of the LRT line construction zones, inducing significant delays to traffic. Data on travelers’ behavioral responses and responses to real-time information were obtained by conducting a survey on a sample of users of the main road affected by the construction. The survey also investigated the effects of West LRT line construction on drivers’ daily commutes, including increases in travel times, mode choices, alternate route choices, and selection of sources of information on traffic conditions. A significant change in the selection of transportation mode was caused by West LRT construction. Throughout the construction period, there was a decrease in the percentage of respondents who reported private vehicles as their first choice and an increase in the percentage of respondents who preferred public transit as their first and second choices. Radio was found to be the most preferred source for traffic updates and detour advice, followed by variable message signs (VMS). The findings of the en-route information model showed that driving experience, employment status, travel time and purpose, and desire for pre-trip information had significant effects on traveler’s rerouting decisions after getting en-route information through VMS. The results from this study are of interest for understanding behavioral changes for the purposes of traffic management, mitigation schemes and design of advanced traveler information systems in response to network disruptions.     

Environments as reinforcer systems in the study of job satisfaction

This paper examined differences in the degree to which fifteen specific sources of job satisfaction were related to and predictive of the overall satisfaction of department chairmen in the six model environments proposed by Holland (1973). The fifteen specific sources of job satisfaction were regressed on overall satisfaction, separately for chairmen in each environment, through the use of incremental stepwise multiple regression procedures. The results indicated that the overall satisfaction of chairmen in these six environments was differentially related to unique weightings and combinations of the fifteen predictor variables. It was concluded that environments, composed of essentially similar groups of people in different organizations, serve as job satisfaction reinforcer systems in a manner similar to organizations as illustrated by Dawis.     

Effects of a coactor's prediction on latencies to predict and indentify stimuli

On each of 300 trials E's confederate (C) verbalized which of two stimuli would occur; then S made a prediction. Following each presentation, S and C pulled a trigger to identify the stimulus. Two latencies were measured: the interval between C's and S's prediction (prediction time), and the interval between stimulus presentation and S's identification response (choice RT). Prediction times were significantly shorter when S's prediction agreed rather than disagreed with C's prediction, when S's preceding prediction was correct rather than incorrect, and when S was female rather than male. Choice RT was influenced by distributions of C's stimulus predictions and C's prediction outcomes in directions supporting an expectancy model.     

Effects of sucrose concentrations on single alternation runway responding in rats

Rats received runway training under alternating reward and nonreward in which rewarded (R) trials provided 32 or 4% sucrose concentration from a drinking tube and nonrewarded (N) trials provided a dry tube or, for half of the rats in the 32% condition, plain water. Both 32 and 4% concentrations yielded faster running on R trials than on N trials; but this effect was reliable only for the 32% condition. Compared to 4% sucrose, 32% sucrose yielded reliably slower running on N trials and unreliably faster running on R trials.     

Audience reaction as a determinant of the speaker's self-persuasion

This paper tests effects of audience feedback on speaker attitudes. One hundred and seven male subjects with initial beliefs on both sides of an issue (women's role) were assigned to speak for or against their own position; then an “audience” provided one of three types of feedback (speaker was sincere, speaker was insincere, no feedback) in a 2 × 2 × 3 design. Subjects who received sincere feedback showed greater change in the direction of their speech than did those who received insincere feedback. No feedback treatments resulted in intermediate change. This sincere > no feedback > insincere ordering of means held for both pro- and counterattitudinal speakers and for both pretest attitudes. A main effect for pretest attitude was also obtained. Two additional control groups allow for a separate analysis of the effects of (1) preparing and delivering the speech, and (2) audience reaction to the speech.     

The effect of physical appearance on the judgment of guilt,interpersonal attraction,and severity of recommended punishment in a simulated jury task

Both an opinion survey and an experimental study were conducted. The survey revealed that substantial majorities of those polled believed (a) that a defendant's character and previous history should influence jurors' decision (79%) and (b) that the defendant's physical appearance should not bias these decisions (93%). The hypothesis, derived from a reinforcement model of interpersonal attraction and previous research on physical appearance, was that attractive defendants would be more positively evaluated than unattractive ones despite the seeming irrelevance of appearance to judicial decisions. The results of a simulated jury task were that physically attractive defendants were evaluated with less certainty of guilt (p < .05), less severe recommended punishment (p < .005), and greater attraction (p < .005), than were unattractive defendants. The importance of independent affective and cognitive components of the attraction process were emphasized.     

Situation-specific variables as determinants of perceived environmental aesthetic quality and perceived crowdedness

It was hypothesized that relevant situation-specific variables may act along with objective physical conditions to determine environmental perception, and that the exclusive use of the physical level of an environmental stimulus to predict behavior may, therefore, be inadequate. A 2 × 4 between-subjects design was employed in which an attitudinally similar or dissimilar confederate interacted with a subject at one of four distances. As hypothesized, subjects who interacted with a similar confederate judged the environment to be of higher aesthetic quality, perceived themselves to be less crowded, and felt affectively more positive than subjects who interacted with a dissimilar other. The results were also interpreted as supporting the utility of the Byrne-Clore (1970) reinforcementaffect model of evaluative responses as a means of predicting environmental perception and the behavioral response to environmental stimuli.     

Informational cues and attributions based on role behavior

A recent experiment by Messick and Reeder (Journal of Experimental Social Psychology, 1972, 18, 482–491) attempted to extend Jones, Davis, and Gergen's (Journal of Abnormal and Social Psychology, 1961, 63, 302–310) classic finding that out-of-role behavior.is more informative for person perception than in-role behavior. It is argued, however, that this study confounded two variables, role performance and occupation. Evidence is presented that the occupation variable alone could have produced Messick and Reeder's results. Both variables seem to affect attributions. The importance of these findings for relating attribution theory and role theory is discussed.     

How Palestinian students invoke the category “human” to challenge negative treatment and media representations

Dehumanisation of opponents in conflict has been shown to be a common and damaging feature in the media. What is not understood is how this dehumanisation is challenged, which is the novel contribution that this research will make. Drawing on focus groups (four focus groups each with four to six participants) conducted in the West Bank in 2015 that discussed media coverage of international conflict, this article demonstrates the ways in which young Palestinian participants attempt to rehumanize themselves in the context of the Israeli–Palestinian conflict. Discursive analysis demonstrates how this was achieved in a number of ways: categorising Palestinians as “human being”; by directly and explicitly challenging the suggestion that Palestinians are less than human; by drawing the enemy into the category “human”; and by embodying the “human.” These findings, the first to address the talk of young Palestinians about the reporting of violent conflicts around the world, demonstrate the importance of categorization and how, in this case, the specifics of the use of the (human) category work to rehumanize Palestinians in the face of (claims of) dehumanisation.
