Peer isolation and drug use among white non-Hispanic and Mexican American adolescents.

The social-emotional characteristics and drug-use patterns of adolescents who reported having no friends (i.e., isolates) were compared to those of adolescents in drug-using and non-drug-using peer groups. Adolescents who did not have drug-using peers reported the lowest drug use and those with drug-using peers had the highest drug use, with adolescents who were isolated falling in between. Isolated youth reported more shyness, greater feelings of alienation, and lower social acceptance than did those in the other groups. Isolated youth also reported more anger and depression than did youth with non-drug-using peers, but less anger and equivalent depression when compared to adolescents with drug-using peers. Results are discussed in terms of social-emotional characteristics of isolated youth and risk/protective factors.     

Outcome Knowledge and Under‐reporting of Safety Concerns in Aviation

High‐risk industries may learn from accidents, incidents and unsafe behaviours if they are reported and investigated. Despite this, significant under‐reporting of safety concerns occurs. One possible explanation is that because concerns cannot always be reported immediately, the outcome of the concern may influence whether reports are made. In Study 1, participants judged six vignettes in which unsafe acts were described: bad outcomes were judged as more likely to be reported than identical acts with innocuous outcomes. Informing participants that luck may determine whether an outcome is innocuous or bad could increase the reporting of unsafe acts with innocuous outcomes. Although implicit prompts did not increase the likelihood of reporting innocuous outcomes (Study 2), there was evidence that explicit prompts to report safety issues with innocuous outcomes increased the likelihood of reporting. Suggestions for further research and a means to reduce the effect of outcome bias on under‐reporting are presented. Copyright © 2015 John Wiley & Sons, Ltd.     

The relationship between romantic and prenatal maternal attachment: The moderating role of social support

The aim of this study was to examine the relationships between three types of maternal attachment bonds: anxious romantic, avoidant romantic and prenatal. The moderating role of perceived social support is also analysed. Ninety-one pregnant women in or near their thirtieth week of gestation (M = 29.59; SD = 4.57) were recruited, all of whom completed a series of questionnaires to assess the quality of their romantic and prenatal attachment bonds and their levels of perceived social support. The results reveal that both anxious and avoidant romantic attachments were significantly associated with low levels of maternal prenatal attachment. Moreover, the level of social support perceived during pregnancy moderated the relationship between anxious and prenatal attachments but had no effect on avoidant romantic and prenatal attachments. Our discussion of these findings considers the emotional and behavioural characteristics of various forms of insecure romantic attachments. Overall, the data highlight the relevance of the quality of intimate close relationships on maternity experiences and women's caregiving abilities.     

Photoinduced volume changes related to photoinduced anisotropy in chalcogenide glasses

We report metastable photoinduced volume expansion (hyperexpansion) of up to 10 µm in height and several millimetres in diameter for the chalcogenide glass As 2 S 3 . This is an order of magnitude larger than reported to date in any material, including chalcogenide glasses. We suggest a model for the effect and propose that its origin is similar to the origin of photoinduced anisotropy in glassy chalcogenides proposed earlier. The model is based on the anisotropic chemical bonding found in most chalcogenide glasses; the anisotropy arises from the fact that chalcogen atoms exhibit both strong covalent bonding and weak van der Waals bonding. The origin of the photoinduced volume changes (expansion and contraction) is in a thermally induced diffusion, or athermal tunnelling, of photoexcited chalcogen atoms, with possible subsequent sublimation from the sample surface. The primary role of hyperpolarizable van der Waals bonds is supported by the absence of photoinduced volume changes in the chalcogenide glass Ga 1.4 La 0.6 S 3, in which chalcogen atoms do not bond via van der Waals bonds.     

Analysis of five cases with neurogenic stuttering following brain injury in the basal ganglia

This study examined stuttering patterns in five patients with basal ganglia injury. None of the patients had a history of developmental stuttering. Four patients were right-handed; one patient was ambidextrous. Stuttering tests administered to patients assessed sentence repetition, reading aloud, explanations of a comic strip, and conversation. Accessory behaviors such as facial grimaces, associated movements of the limbs, and avoidance behaviors were observed. The results of this study differ from those of previous studies of neurogenic stuttering in several respects: (1) blocks were frequently observed. (2) Adaptation was observed. (3) Almost all stuttering occurred at the initiation of words. (4) Across patients, stuttering frequency did not vary in a consistent manner with speaking task. New speech characteristics for neurogenic stuttering without aphasia following injury to the basal ganglia are described.Educational objectives: After reading this text, the reader will be able to: (1) provide characteristics of neurogenic stuttering after the basal ganglia in patients without aphasia; (2) discuss the difference of the features and characteristics of stuttering between previously reported patients and present patients.     

Exploring urban students' constructions about school, work, race, and ethnicity

This qualitative study is an exploration of 32 urban high school students' narratives about the connection between school, work, and societal expectations of their future success related to their racial and ethnic background. The sample varied along 2 contextual dimensions: participation in a psychoeducational intervention (Tools for Tomorrow) and developmental status (i.e., half the sample were 9th-grade students and the other half were 12th-grade students). Using consensual qualitative research, the narratives revealed 3 major domains: future orientation; students' perceptions of society's expectations based on race and ethnicity; and students' perception of the role of their race and ethnicity in future success. Results reveal that the majority of students endorse a connection between school and work, believe that society holds low expectations for them based on their racial and ethnic background, and cannot predict their future success based on their background.     

Influence of motoric encoding on forgetting function of memory for action sentences in patients with Alzheimer's disease

This study assessed whether verbal encoding and motoric encoding have different effects on the forgetting function for action sentences of patients with Alzheimer's disease. Subjects were 13 healthy elderly adults and 10 patients diagnosed with Alzheimer's disease. Three tasks were used: verbal tasks, subject-performed tasks, observed tasks. On the verbal tasks, subjects only heard the action sentences as read to them. On the subject-performed tasks, subjects heard, then performed each action sentence. On the observed tasks, subjects heard the action sentences read while observing the object mentioned in each action sentence. After presentation of each task, subjects conducted immediate and 30-min. delayed recall tests, and then a recognition test. Analysis indicated recall performance for subject-performed tasks was significantly better than that for verbal tasks and observed tasks at both immediate and delayed recall in each group. On the recognition test, carrying out the action had no effect, but for both groups recognition was enhanced by observing the object. Elderly adults performed significantly better than patients on all tasks of recall and recognition. However, the results indicate that patients with Alzheimer's disease can use multimodal resources from motoric encoding even if time passes.     

A distant mirror: Memories of parents and friends across childhood and adolescence

Memories that were easily accessible (i.e., quickly retrieved in a memory‐fluency task) of Italian university students were assessed. They were from four periods of life: preschool, elementary school, middle school, and high school/university. Half of the participants were instructed to recall only memories involving parents, and the other half memories involving friends. Across age at the time of remembered events, only memories of friends increased in frequency. For parental memories (but not friend memories), the proportion with negative affect increased over age, especially for males. There were also differences related to whether memories were episodic or generic. It was concluded that memories of different periods of childhood and adolescence can serve as a reflective mirror for developmental changes in parent–child and friendship relationships.
