Antecedents of Underemployment: Job Search of Skilled Immigrants in Canada

We investigate factors that skilled immigrants can improve in order to have better job search outcomes, in particular to avoid underemployment. We test an unfolding model which considers barriers faced by skilled immigrants during their job search (language and cultural barriers, and the lack of social support in the receiving country), job search constructs and job search outcomes (including underemployment). We collected data through an online questionnaire and obtained 357 usable responses from skilled immigrants in Canada. The hypotheses were tested with partial least squares (PLS). Language fluency and cultural knowledge were positively related to both job search clarity and job search self‐efficacy. Social support was only related to job search self‐efficacy. Job search clarity was related to job search intensity. Job search intensity was related to the number of interviews, which in turn, was related to the number of job offers. Finally, the number of job offers was negatively related to underemployment. Our paper contributes to the understanding of the job search of skilled immigrants by examining factors that can help them overcome obstacles and obtain better job search outcomes.     

Technology in Nonsectarian and Religious Private Schools

The authors report the results of a survey on technology access and use in both religious and nonsectarian schools in the state of Illinois. Four hundred surveys were sent to a cross section of private schools, with a response rate of 45%. The study demonstrates there were only minimal differences between sectarian and nonsectarian schools and that they both had adequate, up-to-date equipment. Most schools provided their students and faculty with access to computer/internet technology in dedicated labs, media centers, and classrooms. The study does show that while both religious and nonsectarian private schools have the tools to integrate technology into the curriculum, and principals who positively rate the use of computer technology, most principals report that a majority of their teachers do not make use of technology in ways that promote higher-order thinking.     

Immersion and emotion: their impact on the sense of presence.

The present study is designed to test the role of immersion and media content in the sense of presence. Specifically, we are interested in the affective valence of the virtual environments. This paper describes an experiment that compares three immersive systems (a PC monitor, a rear projected video wall, and a head-mounted display) and two virtual environments, one involving emotional content and the other not. The purpose of the experiment was to test the interactive role of these two media characteristics (form and content). Scores on two self-report presence measurements were compared among six groups of 10 people each. The results suggest that both immersion and affective content have an impact on presence. However, immersion was more relevant for non-emotional environments than for emotional ones.     

Can a before-school physical activity program decrease bullying victimization in disadvantaged children? The Active-Start Study

Background/ObjectiveTo test the effectiveness of an 8-week before-school physical activity program to reduce bullying victimization among a group of socially disadvantaged children in the Active-Start study.MethodA non-blinded randomized controlled trial was conducted in three public schools classified as highly vulnerable and located in a deprived area of Santiago (Chile). A total of 5 classes participated, totaling 170 fourth grade children. The intervention was delivered before starting the first school-class (8:00–8:30 a.m.). The program lasted for 8 weeks. Primary outcome measurement on bullying victimization was assessed by the CUBE questionnaire at baseline and post-intervention.ResultsThere was a statistically significant reduction in the probability of suffering physical bullying (OR= 0.18, 95% CI, 0.04-0.82; p= .027) and verbal bullying (OR=0.13, 95% CI, 0.02-0.97; p= .046) after the 8-week program.ConclusionsParticipation in an 8-week before-school physical activity intervention implemented in schools located in a disadvantaged district in Santiago (Chile) resulted in lower levels of bullying victimization among study participants. The Active-Start program may be a feasible and potentially scalable intervention option to improve the climate and pro-sociality environment at schools.     

Animacy increases second target reporting in a rapid serial visual presentation task

Attentional blink occurs when two target items, T1 and T2, are presented within brief moments of each other in a series of rapidly presented items and participants fail to report T2. The purpose of the present study was to examine the effect of characteristics of T2 on T2 reporting. Participants (N = 67) completed 4 blocks of 40 trials. Each trial consisted of 15 images, two of which were designated as T1 and T2. T2 was manipulated in three ways: animacy (animate or inanimate), threat (threatening or nonthreatening), and lag (200 ms or 400 ms after T1). The results indicated that more T2s were reported at the longer lag and that animate objects were reported more often than inanimate objects at both lags. Threat did not have a significant effect on T2 reporting although it interacted with lag: threatening objects were reported more frequently than nonthreatening objects at lag 2 but this trend reversed at lag 4. The results were consistent with the animate monitoring hypothesis, which claims that animate objects, because of their importance in ancestral environments, attract attention more easily than inanimate objects. Animate objects appear to capture attention more easily than inanimate objects as second targets in a rapid serial visual presentation task. This result is similar to animacy advantages reported with other attention tasks and with memory tasks.
