Talking about the silent fear: adolescents' experiences of violence in an urban high-rise community

The self-reported violent experiences of adolescents living in a public-subsidized urban high-rise building were examined. This effort was part of an interdisciplinary, community-university collaboration program called the HOME (High-rise On-site Multifamily Environments) Family Support Project. A survey of violent experiences and a one-on-one structured interview were conducted with 20 adolescent residents. Results of the quantitative and qualitative analyses revealed high degrees of exposure to violence among these adolescents, concerns for their personal safety, as well as insights into what they believe adults could and should be doing to address increasing levels of community violence. The implications of these results for conducting ecologically valid research on sensitive issues with adolescents and for family support program planning are discussed.     

Response rates track the history of reinforcement times

When conditioning involves a consistent temporal relationship between the conditioned stimulus (CS) and unconditioned stimulus (US), the expression of conditioned responses within a trial peaks at the usual time of the US relative to the CS. Here we examine the temporal profile of responses during conditioning with variable CS-US intervals. We conditioned stimuli with either uniformly distributed or exponentially distributed random CS-US intervals. In the former case, the frequency of each CS-US interval within a specified range is uniform but the momentary probability of the US (the hazard function) increases as time elapses during the trial; with the latter distribution, short CS-US intervals are more frequent than longer intervals, but the momentary probability of the US is constant across time within the trial. We report that, in a magazine approach paradigm, rats' response rates remained stable as time elapses during the CS when the CS-US intervals were uniformly distributed, whereas their response rates declined when the CS-US intervals were exponentially distributed. In other words, the profile of responding during the CS matched the frequency distribution of the US times, not the momentary probability of the US during the CS. These results are inconsistent with real-time associative models, which predict that associative strength tracks the momentary probability of the US, but may provide support for timing models of conditioning in which conditioned responding is tied to remembered times of reinforcement.     

Making the case for objective performance metrics in newborn screening by tandem mass spectrometry

The expansion of newborn screening programs to include multiplex testing by tandem mass spectrometry requires understanding and close monitoring of performance metrics. This is not done consistently because of lack of defined targets, and interlaboratory comparison is almost nonexistent. Between July 2004 and April 2006 (N=176,185 cases), the overall performance metrics of the Minnesota program, limited to MS/MS testing, were as follows: detection rate 1:1,816, positive predictive value 37% (54% in 2006 till date), and false positive rate 0.09%. The repeat rate and the proportion of cases with abnormal findings actually been reported are new metrics proposed here as an objective mean to express the overall noise in a program, where noise is defined as the total number of abnormal results obtained using a given set of cut-off values. On the basis of our experience, we propose the following targets as evidence of adequate analytical and postanalytical performance: detection rate 1:3,000 or higher, positive predictive value>20%, and false positive rate<0.3%.     

Negotiating Multiple Identities,Constructing Western‐Muslim Selves in the Netherlands and the United States

This article evaluates the psychological processes, discursive practices, and sociopolitical mechanisms underlying the identity reconstruction of Muslim immigrant women in the United States and the Netherlands. Specifically, it focuses on the ways in which Muslim immigrant women who are embedded in both Islamic and Western cultures negotiate their traditional and modern identities and self‐representations and construct a coherent self‐narrative about their bicultural existence as “Western‐Muslim.” The qualitative evidence presented here expands existing theoretical and empirical discussions on biculturalism and acculturation by demonstrating the ways in which contextual factors define the negotiation repertoire that is available to bicultural individuals. The findings of this article also call into question some of the earlier findings on cultural conflict hypothesis, because it shows that successful negotiation of bicultural identities depends not so much on whether the individual perceives these identities and cultures to be compatible with each other, but rather on the availability of a coherent self‐narrative of belonging to both cultural worlds.     

Every scar tells a story: Insight into people’s self-injury scar experiences

Scarring, a common and salient consequence of non-suicidal self-injury (NSSI), remains an under-explored issue in the field. Thus, the current investigation explored NSSI scar perspectives using online testimony from members of a popular NSSI message board; focus was attenuated to a series of message board posts pertinent to people’s experiences with scars resulting from NSSI. Data (message board posts) were collected using the website’s search function. A total of 53 posts involving discussion of people’s NSSI scar perceptions and experiences were retained. A thematic analysis of the data indicated that individuals viewed their scars in a number of ways. Many viewed scars in a resilient manner, often in the context of a self-narrative. Others, however, were unaccepting of their scars (e.g. expressed feelings of shame, hatred, or disgust). For some, they were able to gradually accept their scars but only after a period of difficulty. And, finally, some individuals expressed mixed feelings toward their scars (e.g. a love/hate relationship). Hence, scars stemming from NSSI seem to differentially impact individuals who self-injure. Possible implications for research and clinical practice are discussed.     

Comparison of force, power, and striking efficiency for a Kung Fu strike performed by novice and experienced practitioners: preliminary analysis

This paper presents a comparison of force, power, and efficiency values calculated from Kung Fu Yau-Man palm strikes, when performed by 7 experienced and 6 novice men. They performed 5 palm strikes to a freestanding basketball, recorded by high-speed camera at 1000 Hz. Nonparametric comparisons and correlations showed experienced practitioners presented larger values of mean muscle force, mean impact force, mean muscle power, mean impact power, and mean striking efficiency, as is noted in evidence obtained for other martial arts. Also, an interesting result was that for experienced Kung Fu practitioners, muscle power was linearly correlated with impact power (p = .98) but not for the novice practitioners (p = .46).     

Social axioms in Iran and Canada: Intercultural contact, coping and adjustment

A comparison was made between Iranian participants living in Iran, Iranian immigrants to Canada, and Canadian-born participants on the Social Axioms Scale (SAS), including a sixth dimension, Harmony. The Iranian immigrants to Canada endorsed views that were intermediate between the other two groups. In the data from Iran, the relationships between social axioms on the one hand and measures of active coping and adjustment on the other were examined. Belief in Reward for Application predicted Active Coping; acknowledgment of Social Complexity predicted Life-Satisfaction; and endorsement of belief in Harmony predicted Mastery. Those whose beliefs on Harmony and Social Complexity were closer to their country mean were higher on Mastery and Self-Esteem, but those whose beliefs on Fate Control were closer to the country mean showed lower Life-Satisfaction.     

Meanings of the Hijab: Views of Canadian Muslim women

This study demonstrates the individualized phenomenological experiences of Muslim‐Canadian women through their relationships with head covering, most commonly known as the hijab. By conducting in‐depth interviews with ten women, five who cover and five who do not, we sought to understand their day‐to‐day experiences with covering, and how their interpretations of these experiences were related to them as individuals, as well as to broader social contexts. Through the use of Interpretative Phenomenological Analysis, we found that the women's experiences can be regarded as an interplay between internal experience, that is, the personal meanings that the women placed on wearing or not wearing a headscarf, and external experience, that is, their interpretations of outside events and treatment by others as related to the headscarf. Their experiences were also embedded in the contexts of their cultural and religious communities, and broader Canadian society. Consistent with previous work, themes such as Muslim identity, religiosity and modesty were highlighted by the women, however, rather than focusing on general experiences across participants, we give primary attention to how these themes unfolded in the individual women's lives. © 2016 John Wiley & Sons Australia, Ltd, Asian Association of Social Psychology and Beijing Normal University
