An Investigation of Title Ambiguity in the Health Sciences Literature

This research investigates what most catalogers already know—titles alone do not identify works sufficiently. Repetitive titles like “Annual Report” are just the tip of the iceberg. To explore the extent of ambiguity occurring in large sets of health science bibliographic data, the entire National Library of Medicine and Lane Medical Library catalogs and a sample from the PubMed database were analyzed. After measuring the uniqueness of titles, results were recalculated to determine the effect of appending date and/or edition. This initial evidence supports further exploration of whether such structured titles might serve as singular bibliographic identities.     

Design approach for a high-resolution microwave imaging radio camera

The angular resolution of an imaging device is the order of the reciprocal of the number of wavelengths across the aperture. To achieve the high resolution typical of optical instruments at microwaves, apertures miles in size may be required. The requirements for such a device, called a radio camera, are conformality with the terrain, a sparsely filled aperture of randomly (or nearly so) located elements, self-adaptive beam forming and a source of microwave illumination. Based on this design approach, a 1000-ft L-band radio camera is under development at the Valley Forge Research Center of the Moore School. This paper discusses the status of current development of the device.     

Patellofemoral pain,body morphology and alignment in female pubertal dancers: One-year follow-up

The aim of this study was to assess changes in body morphology, anatomical alignment and prevalence of patellofemoral pain (PFP) in young female dancers along one year of pubertal growth, and to identify the risk factors related to PFP in these young dancers. Both legs of 60 dancers were evaluated during grade 7 and again after 1-year. At each of these points in time, the dancers were interviewed concerning their background, and anthropometric measurements, lower-limb physical examinations and knee ultrasound scans were performed. Morphological parameters changed significantly from baseline to follow-up. PFP was found in 53.3% of the dancers’ knees at baseline. At follow-up, 55.4% of the asymptomatic knees at baseline developed PFP, and only 9.4% of the symptomatic knees at baseline recovered. Lower BMI was identified among dancers who developed PFP during follow-up compared with dancers with no PFP, either at baseline or at follow-up. A positive grinding and positive Patellar Inhibition Test (PIT) were found to be risk factors for PFP at follow-up. A high prevalence of young dancers suffered PFP, from injuries they sustained mostly during the 1-year of dance practice. Parameters predisposing the dancers to PFP should be identified at early stages of dance class.     

Socialization experiences and coping strategies of adults raised using spoken language

This investigation concerned the socialization experiences and coping strategies of a group of 28 deaf adults who were raised using spoken language. Most respondents reported some level of social isolation because of (1) limitations in communication with hearing peers; (2) missing information in social, academic, and work settings; and (3) a sense of being "different." Most participants also reported strategies used to reduce isolation and mitigate the social difficulties associated with their hearing loss.     

Single parents, stepparents, and the susceptibility of adolescents to antisocial peer pressure

According to a recent report, adolescents living in single-parent households are more likely to engage in deviant activity than are youngsters living with both natural parents, or in single-parent, extended households, allegedly because the presence of an additional adult provides greater control of youngsters' behavior. In the present study, fifth, sixth, eighth, and ninth graders from 1 of 3 family structures (both natural parents, mother alone, or 1 natural parent and a stepparent) were compared with respect to their susceptibility to peer pressure to engage in deviant activity. All comparisons controlled for sex, age, socioeconomic status, maternal employment, and patterns of family decision making. Youngsters living with both natural parents were less susceptible to pressure from their friends to engage in deviant behavior than youngsters living in other family structures. More important, youngsters growing up in stepfamilies--in the presence of an additional adult--were equally at risk for involvement in deviant behavior as were their peers growing up in single-parent households.     

Ethnicity and Community Context as Moderators of the Relations between Family Decision Making and Adolescent Adjustment

This study investigated whether the impact of 3 types of family decision making on the adjustment of 14–16-year-old youth was moderated by ethnicity, community context, or both. For joint and unilateral youth decision making, community context interacted with ethnicity in 3 patterns of influence: for Hispanic-American youth, variations in decision making had a stronger impact in ethnically mixed than in predominantly white communities; for African-American youth, the negative impact of unilateral youth decision making was stronger in predominantly white communities; and for Asian- and European-American youth, community context did not make a difference. For unilateral parental decision making, the popular hypothesis that apparent ethnic differences in the influence of parental strictness on adolescent adjustment are primarily due to differences in community context was not supported. Rather, the positive impact of unilateral parental decision making was similar among African-American youth living in predominantly white, and more affluent, communities or in more disadvantaged, ethnically mixed neighborhoods. The negative impact of authoritarian parenting was similar among European-American youth living in less advantaged communities as well as more affluent ones. There was no relation between unilateral parental control and adolescent adjustment of Asian- or Hispanic-American youth in either type of community.     

Adolescents' emotion regulation in daily life: links to depressive symptoms and problem behavior

This study examined links between emotion regulation and adjustment in a sample of 152 adolescents in Grades 7 (M age = 12) and 10 (M age = 15). Emotion regulation was assessed using the experience sampling method, in which adolescents provided multiple reports about the intensity, lability, and strategies used to regulate negative emotions across 1 week. Adolescents also completed self-report measures of adjustment. Adolescents who reported more intense and labile emotions and less effective regulation of these emotions also reported more depressive symptoms and problem behavior. Responding to negative emotions with disengagement (e.g., denial) or involuntary engagement (e.g., rumination) was less effective in regulating negative affect, and greater use of these strategies was related to higher levels of depressive symptoms and problem behavior.     

Youth online political expression in non-political spaces: implications for civic education

ABSTRACT

Based on an in-depth qualitative content analysis of post-election discourse in three online creative communities (Scratch, Archive of Our Own, and hitRECord), we examine the significance of youth political expression in non-political online spaces, and its implications for civic education. We find that these spaces offer a valuable window into the main concerns experienced by youth around the election, which they voice through unique modes of expression. Online spaces facilitate connections between the personal and the political, while highlighting the social aspects of youth participation and learning in regard to civic issues. At the same time, participants exhibit uncertainty regarding the limits of online expression and the potential consequences of speaking out. We argue that online spaces should be acknowledged as a significant channel for youth political expression and socialization, and consider how the practices encountered there could shape our approach to civic education.
