Supporting Veteran Transitions to the Academic Setting: VA on Campus

In this case study, we assessed academic functioning, service satisfaction, and needs of student veterans at a community college who had accessed the Veterans Health Administration (VHA) Student Veteran Health Program (SVHP) (n = 36). The SVHP provides outreach and behavioral health services directly on a large community college campus to overcome common barriers to engagement in mental health care (e.g., distance from a VA medical center). Academic difficulties that were most commonly reported were in the areas of retention of information, meeting deadlines, and cooperation with other students. Overall, the majority of student veterans who received services in the SVHP were satisfied (76.5%). Services targeting attention and concentration and utilization of educational benefits were highlighted as important by student veterans. This case study of VA services delivered within the community college setting provides important insights into how to design VA services to target the needs of student veterans. Specific recommendations for supporting student veterans on a community college campus are discussed.     

The Use of Statistical Significance: A Commentary Related to Franks and Huck

Abstract

This paper focuses on the processes by which people become high school coaches. Occupational choice, professional socialization, and organizational socialization are examined, using qualitative data drawn from naturally occurring observations of coaches and informal discussions and in-depth interviews with them. Over 50% of the coaches had decided that they wanted to become a coach before entrance into college. The decision to become a coach was subjectively warranted by personal characteristics and experiences in sports, a devotion to sport, and a desire to work with young people. Youth sport coaching and student teaching which involved coaching constituted the only formal professional socialization that most of the coaches received. However, because almost all of the coaches participated in organized youth and/or high school athletics, they had a first-hand opportunity to observe their own coaches and acquire some informal images and impressions about the coaching occupation from them. Regardless of whether a neophyte began as an assistant or a head coach, technical aspects of the job and the occupation's culture were acquired by observing and listening to more experienced coaches. Through these experiences, collective understandings began to form, and the shared meanings about the occupational culture took shape. Reality shock for most novice coaches came in the form of understanding the importance the coaching culture assigns to long hours and hard work and to the realization that coaching does take an enormous amount of time. By the end of the first season, a symbolic transformation takes place and internalization of institutional expectations occurs as the neophyte begins to understand what coaching is all about.     

Providing access to electronic information resources in further education

This article aims to provide a baseline for future studies on the provision and support for the use of digital or electronic information services (EIS) in further education. The analysis presented is based on a multi‐level model of access, which encompasses access to and availability of information and communication technology (ICT) resources, access to and availability of EIS resources, and the third leg of staff skills and their development. The research was conducted within the third cycle of the JISC (Joint Information Services Committee) User Behaviour Monitoring and Evaluation Framework, in 2001/2002. Evidence was gathered from library and information service web sites and various stakeholders, including library and information service staff, academic staff and students to generate insights into the provision of access to EIS in further education. Sector‐wide funding initiatives have had a significant impact on ICT infrastructures, and these attract a positive response from students. EIS are represented on some library web sites but both web site development and EIS availability is very much less advanced than in higher education. Staff, however, lack sufficient dedicated access to ICT to be able to develop their own skills and use. There remains a low level of access to electronic information resources, with only limited access to these resources through library web sites. LIS managers face a number of challenges in enhancing this provision, including licensing arrangements, tight budgets that need to be spread across many discipline areas, and the absence of EIS designed specifically for the further education student. The other key challenge lies in the provision of time and opportunity for academic and LIS staff to develop their ICT and EIS skills, and, more generally in the further development of the role of Information and Learning Technology (ILT) Champions.     

Developmental Status and Social–Emotional Functioning of Young Children Experiencing Homelessness

The developmental status and social–emotional functioning of young children who are homeless has received inadequate attention in spite of high rates of homelessness among families with young children and the potentially negative impact of homelessness and associated stressors on children’s well-being. The aim of this study was to gain understanding of homeless children’s social–emotional adjustment and their functioning in language, motor, and cognitive skills. We also examined gender and age differences in those areas of development. The sample included 328 children residing with their parents in one of 11 emergency shelter or transitional housing programs for families who were experiencing homelessness in a central North Carolina county. Child case managers administered the Brigance Early Childhood Screen II and the Ages and Stages Questionnaire: Socioemotional form in the shelter setting. Findings indicated variability in competence among the children, with some children performing above average on the developmental screening and demonstrating few social–emotional problems. However, developmental scores for overall functioning of the sample were significantly below the norming group, with particularly low functioning in language and communication skills. Parents of 24.8 % of the children had substantial concerns about their children’s mental health status. Although there are individual differences in adjustment of children experiencing homelessness, results support wide-scale screening and access to early intervention for these vulnerable children. Future investigations could be directed to identifying factors associated with resilience among children without homes.     

Structural Pluralism in Journalism and Media Studies: A Concept Explication and Theory Construction

This article critically reviews scholarship on structural pluralism (Tichenor, Donohue, & Olien, 1973 Tichenor , P. J. , Donohue , G. A. , & Olien , C. N. ( 1973 ). Mass communication research: The evolution of a structural model . Journalism Quarterly , 50 , 419 – 425 .[Crossref], [Web of Science ®] , [Google Scholar], 1980 Tichenor , P. J. , Donohue , G. A. , & Olien , C. N. ( 1980 ). Community conflict & the press . Beverly Hills , CA : Sage . [Google Scholar]) in journalism and media studies. Relying partly on a concept explication and theory construction process (McLeod & Pan, 2004 McLeod , J. M. , & Pan , Z. ( 2004 ). Concept explication and theory construction . In S. Dunwoody , L. B. Becker , D. M. McCleod , & G. M. Kosicki (Eds.), The evolution of key mass communication concepts honoring Jack M. McLeod (pp. 13 – 76 ). Cresskill , NJ : Hampton . [Google Scholar]), the article explicates structural pluralism as a multifaceted concept with multiple dimensions and indicators. While reviewing relationships or hypotheses between structural pluralism and various outcomes, the article then discusses and proposes issues and agendas for future studies.     

Examining the association of job tenure,employment history,and organizational status with employee dissent

The purpose of this study was to assess the relationship between temporal and structural components of organizational life (i.e., job tenure, employment history, and organizational history) and employee dissent. This was accomplished by comparing respondents’ reports about their tendencies to use varying strategies for dissent to their reports about present job tenure, number of full‐time employers, total years work experience, and organizational status. Structural equation models were used to examine the association between temporal measures (job tenure, number of full‐time employers, total years work experience), structural measures (organizational status) and dissent constructs. Findings indicated that articulated dissent use was associated with management status, whereas latent dissent use was associated with nonmanagement status, increases in present job tenure and decreases in number of full‐time employers and total years work experience.     

Longitudinal Relations Among Language Skills,Anger Expression,and Regulatory Strategies in Early Childhood

Researchers have suggested that as children's language skill develops in early childhood, it comes to help children regulate their emotions (Cole, Armstrong, & Pemberton, 2010; Kopp, 1989), but the pathways by which this occurs have not been studied empirically. In a longitudinal study of 120 children from 18 to 48 months of age, associations among child language skill, observed anger expression, and regulatory strategies during a delay task were examined. Toddlers with better language skill, and whose language skill increased more over time, appeared less angry at 48 months and their anger declined more over time. Two regulatory strategies, support seeking and distraction, explained a portion of the variance in the association between language skill and anger expression after toddlerhood.     

The Influence of Individual Cognitive Style on Performance in Management Education

This paper reports the outcomes of an empirical study undertaken to explore the possibility that cognitive style may be an important factor influencing performance on certain types of task in management education. A total of 412 final year undergraduate degree students studying Management and Business Administration were tested using the Allinson- Hayes Cognitive Style Index. Their cognitive styles were then compared with assessment grades achieved for academic modules, the task categories of which were deemed to be consonant with either the Wholist/Intuitive or the Analytic style of working. Overall ability defined by final degree grades was also tested against individuals' cognitive styles. As expected, students whose dominant cognitive styles were Analytic attained higher grades for long-term solitary tasks involving careful planning and analysis of information. However, contrary to expectations, performance on tasks believed to be more suited to the Wholist/Intuitive style was also higher for Analytic individuals, as was overall ability defined by final degree grades. The results were discussed in terms of the nature of the tasks and the need for methods of performance assessment that are independent of an orientation bias. Without this, it is argued, employment selection criteria may favour the wrong type of candidate in some circumstances.
