Abstract Stopovers comprise a significant proportion of the time that many birds spend migrating, and researchers have long relied on these events to define and classify broader migratory strategies. Analyses of stopovers often assume that individuals stop primarily or exclusively in order to replenish energy stores, but other non-fueling behaviors have also been described during stopover events and can influence stopover incidence and duration. Here, we discuss the growing demand for understanding these non-fueling behaviors and for restoring the inherent behavioral complexity to stopover events. We begin by describing how light-weight tracking technologies allow researchers to follow individuals along their entire migratory journeys, capturing stopovers that controvert the traditional stop–refuel–resume paradigm. We then discuss 5 well-identified non-fueling behaviors—recovering, sleeping, waiting, information gathering, and social interactions—and examine how including these behaviors can alter interpretations of individual movement paths. Finally, we outline emerging directions for identifying these behaviors and look to larger implications for population management and site conservation along migratory flyways.

Although violence is a frequently researched topic, little is known about how different social features influence information gathering from violent interactions. Regions of an interaction that provide contextual information should receive more attention. We predicted the most informative features of a violent social interaction would be faces, points of contact, and objects being held. To test this, we tracked the eyes of 90 participants as they viewed images of social interactions that varied with respect to violence. When viewing violent interactions, participants attended significantly less to faces and significantly more to points of contact. Moreover, first-fixation analysis suggests that some of these biases are present from the beginning of scene-viewing. These findings are the first to demonstrate the visual relevance of faces and contact points in gathering information from violent social interactions. These results also question the attentional dominance of faces in active social scenes, highlighting the importance of using a variety of stimuli and contexts in social cognition research.

Understanding environmental conditions of neighbourhoods can play a critical role in maintaining social interactions among residents. This research is carried out to assess the effect of street permeability on the degree of social cohesion among residents in a residential neighbourhood in Penang, Malaysia. A total of 250 households participated in the study. The findings indicate that permeability can account for a significant proportion of the variance in residents’ social cohesion. Residents living in less permeable streets are more likely to have a high social cohesion with their neighbours. The results further support the defensible space concept which advocates closed streets.Keywords: Permeability; social cohesion; road type; residential neighbourhoodeISSN 2398-4295 © 2018.

Social support has a positive impact on quality of life (QoL) in neurotypical older adults and young autistic adults, but the association for older autistic adults is unclear. Autistic adults (n=388; mean age=40-83 years) were recruited via Simons Powering Autism Research for Knowledge research match. Participants completed questionnaires online querying demographic information, depression and anxiety symptomatology, QoL (Physical, Psychological, Social, Environmental, Autism-specific) and social support (instrumental, subjective and social interactions). Regression analyses examined whether different aspects of social support explained the variance in each domain of QoL. A significant proportion of the variance (36-58%) in QoL was explained. Subjective social support significantly contributed to the models for all aspects of QoL; Physical and Psychological QoL were also explained by social interactions, whereas Social, Environmental and Autism-specific QoL were additionally explained by instrumental support. Social support is an important contributor to the QoL of middle-aged and older autistic adults, after accounting for demographic factors and depression. Further studies are required to understand whether age-related changes in social support and QoL are the same for autistic as non-autistic older adults in order to identify and implement appropriate support.

By addition of analytical equipment, scanning transmission accessories and data processing equipment the basic transmission electron microscope (TEM) has evolved into a comprehensive information gathering system. This extension has led to increased complexity of the instrument as compared with the straightforward imaging microscope, since in general new information capacity has required the addition of new control hardware. The increased operational complexity is reflected in a proliferation of knobs and buttons.In the conventional electron microscope design the operating panel of the instrument has distinct control elements to alter optical conditions of the microscope column in different modes. As a consequence a multiplicity of control functions has been inevitable. Examples of this are the three pairs of focus and magnification controls needed for TEM imaging, diffraction patterns, and STEM images.

Purpose Many aging individuals, even those who are healthy, report voice changes that can impact their ability to communicate as they once did. While this is commonly reported, most do not seek evaluation or management for this issue. The purpose of this study was to investigate the prevalence and differences in voice disorders in older adults, along with the effect of fatigue on their social interactions. Method This is a cross-sectional investigation of a community-dwelling sample of individuals aged 60 years or older. Participants completed the Questionnaire on Vocal Performance, the Social Engagement Index subset “Engagement in Social or Leisure Activities,” and the Fatigue Severity Scale. Results Results indicated 32.5% of the 332 participants reported symptoms of voice problems with no difference found between male and female respondents. A slight increase in report of voice problems was noted with each year of age. Participants who self-reported voice problems indicated less interaction in social activities involving communication than those who did not. Finally, as severity of self-reported voice problems increased, an increase was reported by the same individuals for signs of fatigue. Conclusions Voice problems and resulting decreased social interaction are commonly experienced by older individuals. Voice symptoms in older adults have been found to benefit from evidence-based treatment strategies. It is critical to provide education to encourage older individuals to seek appropriate evaluation and management for voice issues through a speech-language pathologist or medical professional.

Abstract The present qualitative study was designed to examine augmentative and alternative communication (AAC) practices, particularly surrounding speech-generating devices (SGDs), in the classroom setting. We focused on three key child participants, their classroom teachers, and associated speech-language pathologists across three different schools. In addition to semi-structured interviews of all participants, six classroom observations per child were completed. Data were coded according to both pre-established and emergent themes. Four broad themes emerged: message-focused AAC use, social interactions within the classroom community, barriers to successful AAC-SGD use, and missed opportunities. Findings revealed a lack of SGD use in the classroom for two children as well as limited social interaction across all cases. We conclude by highlighting the pervasive sense of missed opportunities across these classroom observations and yet, at the same time, the striking resiliency of communicative effort in these cases.

Abstract. Background: The Internet is used by young people at risk of self-harm to communicate, find information, and obtain support. Aims: We aimed to identify and analyze websites potentially accessed by these young people. Method: Six search terms, relating to self-harm/suicide and depression, were input into four search engines. Websites were analyzed for access, content/purpose, and tone. Results: In all, 314 websites were included in the analysis. Most could be accessed without restriction. Sites accessed by self-harm/suicide search terms were mostly positive or preventive in tone, whereas sites accessed by the term ways to kill yourself tended to have a negative tone. Information about self-harm methods was common with specific advice on how to self-harm in 15.8% of sites, encouragement of self-harm in 7.0%, and evocative images of self-harm/suicide in 20.7%. Advice on how to get help was given in 56.1% of sites. Conclusion: Websites relating to suicide or self-harm are easily accessed. Many sites are potentially helpful. However, a significant proportion of sites are potentially harmful through normalizing or encouraging self-harm. Enquiry regarding Internet use should be routinely included while assessing young people at risk.
