Speed of Processing and Face Recognition at 7 and 12 Months

This research examined developmental and individual differences in infants' speed of processing faces and the relation of processing speed to the type of information encoded. To gauge processing speed, 7‐ and 12‐month‐olds were repeatedly presented with the same face (frontal view), each time paired with a new one, until they showed a consistent preference for the new one. Subsequent probe trials assessed recognition of targets that either preserved configural integrity (Study 1: 3/4 profile and full profile poses) or disrupted it while preserving featural information (Study 2: rotations of 160° or 200° and fracturings). There were developmental differences in both speed and in infants' appreciation of information about faces. Older infants took about 60% fewer trials to reach criterion and had more mature patterns of attention (i.e., looks of shorter duration and more shifts of gaze). Whereas infants of both ages recognized the familiar face in a 3/4 pose, the 12‐month‐olds also recognized it in profile and when rotated. Twelve‐month‐olds who were fast processors additionally recognized the fractured faces; otherwise, processing speed was unrelated to the type of information extracted. At 7 months then, infants made use of some configural information in processing faces; at 12 months, they made use of even more of the configural information, along with part‐based or featural information.     

Social Constructivist Practice with Youth

Social constructivism is an important and creative perspective for helping social workers in their work with adolescents. This paper demonstrates how theoretical orientations and clinical techniques that adhere to a social constructivist perspective can be integrated with the developmental realities of adolescence to provide effective social work interventions. Fundamental assumptions are discussed and are related to problems of practice. Case studies are utilized to demonstrate social constructivist principles in clinical work with adolescents.     

The Potential Contributions of Quantitative Research to Symbolic Interactionism

Symbolic interactionism is often mischaracterized as a perspective that rejects quantitative research. We argue that the rich conceptual tradition of symbolic interactionism allows for the use of quantitative data and statistical analysis within a pragmatist epistemology and that this is desirable, especially in conjunction with qualitative data. We discuss types of quantitative data and their appropriate uses and then describe types of contemporary multivariate statistical methods and what they offer. To illustrate these data and analytic techniques, we draw from examples in our area of specialization, criminology, and from our own quantitative work. Researchers can use quantitative data and methods in the service of six core symbolic interactionist concerns—meaning, variation, comparisons, situations, contexts, and probability—and we contend that quantification and statistics pose no threat to the interactionist perspective. In fact, the principled, critical use of quantitative research can enhance it.     

Homeless youths' perceptions of services and transitions to stable housing

Use of available services is low among homeless youths, and how youth make decisions to access services or seek housing is unclear. This study explored perspectives of current and former street youth about these processes. Recruited from the streets and a drop-in center, 27 youth ages 16–24, participated in individual qualitative interviews. Findings from consensual qualitative analyses indicated choices to use services were embedded within developing autonomy and identification with street lifestyles. Themes of self-reliance, substance use, and relationships with street and housed persons were expressed as critical for both using services and transitioning to stable housing. Agency-related factors such as caring staff, a nonjudgmental atmosphere, and flexible policies were perceived as important for service use while youth-related factors such as experiencing major events, being internally motivated, and embracing mainstream values were seen as conducive to transitioning off the streets. Implications for service providers and future research are discussed.     

The Mediating Role of Discoursing in Activity

Categories play a significant role in the coordination of human activities. Collective action within organizations presupposes shared category systems that make institutional priorities and relevancies visible. In this study, some features of the origin, use, and consequences of a categorization tool of modern employment agencies are analyzed. This category system is complex and has come to serve a diverse set of functions (provision of financial and other kinds of assistance to the unemployed, production of a broad range of statistics, etc.). We argue that this multifunctionality of the tool implies that the employment agency officers reflexively attend to the consequences of their actions and monitor what their decisions will imply at different levels. This reflexivity plays a significant role in the services provided to citizens and in the manner in which their needs are visible to the public. We conclude that categorization practices are hidden, but highly significant, features in the production of social facts.     

When Do First-Year College Students Drink Most During the Academic Year? An Internet-Based Study of Daily and Weekly Drinking

Abstract

Objective: The authors investigated the alcohol consumption trajectories among first-year university students. Participants: A sample of 415 students attending a large university in Southwestern Ontario, Canada, was recruited. Methods: Students completed a baseline questionnaire and 26 weekly brief Internet surveys assessing alcohol consumption from September 2006 to April 2007. Results: Findings indicated that alcohol consumption varies considerably as a function of time of the academic year. Overall trends indicate that students drink more heavily at the beginning of each semester and less during exam periods. Daily patterns indicate that most drinking occurs on weekends. The highest drinking days in the first academic year included Halloween, New Year's Eve, and St. Patrick's Day. Conclusions: The present study provides evidence that periods of high and low alcohol consumption are contingent upon specific events and the time of the year.     

The Effect of Religiosity and Campus Alcohol Culture on Collegiate Alcohol Consumption

Abstract

Religiosity and campus culture were examined in relationship to alcohol consumption among college students using reference group theory. Participants and Methods: College students (N = 530) at a religious college and at a state university complete questionnaires on alcohol use and religiosity. Statistical tests and logistic regression were utilized to examine alcohol use, religiosity, and campus environment. Results: Alcohol consumption was significantly higher among students at the university (M = 26.9 drinks) versus students at the religious college (M = 11.9 drinks). University students also had lower religiosity scores (M = 23.8) than students at the religious college (M = 26.5). Students who attend a secular university are 4 times more likely to be moderate or heavy drinkers compared to students attending a religiously affiliated college. Students with the least religiosity were 27 times more likely to be a heavy alcohol user and 9 times more likely to be a moderate alcohol user compared to students with greater religiosity.     

Preparing individual patient data from clinical trials for sharing: the GlaxoSmithKline approach

In May 2013, GlaxoSmithKline (980 Great West Road, Brentford, Middlesex, TW8 9GS, UK) established a new online system to enable scientific researchers to request access to anonymised patient level clinical trial data. Providing access to individual patient data collected in clinical trials enables conduct of further research that may help advance medical science or improve patient care. In turn, this helps ensure that the data provided by research participants are used to maximum effect in the creation of new knowledge and understanding. However, when providing access to individual patient data, maintaining the privacy and confidentiality of research participants is critical. This article describes the approach we have taken to prepare data for sharing with other researchers in a way that minimises risk with respect to the privacy and confidentiality of research participants, ensures compliance with current data privacy legal requirements and yet retains utility of the anonymised datasets for research purposes. We recognise that there are different possible approaches and that broad consensus is needed. Copyright © 2014 John Wiley & Sons, Ltd.
