Stars Versus Starters: The Relationship Between Ability Level and Character in High School Football Players Attending a Major College Football Camp

The image of a University of Miami football player wielding his helmet as a weapon during a brawl with cross-town rival Florida International University was broadcast repeatedly across the national television airwaves in the fall of 2006. This most recent brawl during a collegiate football contest has again fueled the debate: does sport build or reveal character? Sport advocates, former athletes, and coaches unabashedly promote the benefits of sport. Yet, scholars and empirical research have consistently backed the notion that sport may just as well contribute in a potentially damaging manner to the development of children and adolescents if not taught, organized, managed, and led properly (e.g., Beller & Stoll, 1995; Ewing, Gano-Overway, Branta, and Seefeldt, 2002; Petitpas, Cornelius, Van Raalte, & Jones, 2005). Beller and Stoll went a step further in concluding, As such, competitive athletics as it is taught and morally modeled in this country does not appear to cognitively develop young people (p. 361)

Capacity strengthening in malaria research: the Gates Malaria Partnership.

The Gates Malaria Partnership (GMP) includes five African and four European partner institutions. Its research programme has five priority areas involving an extensive range of field-based studies. GMP research has contributed significantly to the development of new research consortia investigating strategies for improving means of malaria control, and has already had an impact on policy and practice. A substantial investment in innovative training activities in malaria has enhanced knowledge and practice of malaria control at all levels from policy making to local community involvement. Capacity development, notably through a PhD programme, has been an underlying feature of all aspects of the programme

Emergence and Migration of a Nearshore Bar: Sediment Flux and Morphological Change on a Multi-Barred Beach in the Great Lakes

Burley Beach (southeastern Lake Huron) exhibits a multi-barred shoreface, the long-term equilibrium morphology characteristic of many low angle, sandy beaches in the Canadian Great Lakes. During a single major storm, a new bar emerged 50-60 m offshore as an irregular trough-crest form, through differential erosion of an existing shore terrace. Emergence, bar growth and offshore migration were associated with: (a) an overall negative sediment balance in the inner surf zone initially (‑2.30 m3>/m beach width), but with a large positive sediment balance (+5.10 m3/m) subsequent to the storm peak and during the storm decay; (b) progradation of the beach step to produce a new shore terrace; and (c) offshore migration of the two outer bars to provide the accommodation space necessary for the new bar. The primary transport mechanisms accounting for emergence of the new bar, its growth and migration were: (a) the mean cross-shore currents (undertow), which always transported suspended sediment offshore; and (b) the onshore transport of suspended sediment by incident gravity wave frequencies early in the storm and subsequently by infragravity waves (at the storm peak and the decay period). The longshore transport of sediment was significant in terms of the gross transport, although the net result was only a small transport to the south-west (historic littoral transport direction). It did not cause bar initiation, but it may have supplied some of the sediment for bar growth. The primary mechanism for bar initiation and growth was the cross-shore displacement of sediment by wave-driven (oscillatory) transport and cross-shore mean currents (undertow).Émersion et migration d’une barre côtière : bilan sédimentaire et changements morphologiques d’une plage à barres multiples des Grands Lacs. La plage de Burley (sud-est du lac Huron) présente une avant-côte à barres multiples, état morphologique caractéristique de l’équilibre à long terme des plages sableuses à pente faible. Au cours d’un seul orage majeur, une nouvelle barre s’est développée à 50-60 m au large de la côte en forme de creux et crête irrégulière, suite à l’érosion d’une terrasse côtière. L’émersion, la croissance et la migration de la barre est attribuable à (a) un bilan sédimentaire négatif dans la zone interne du ressac (‑2,30 m3/m), mais à un bilan sédimentaire positif (+5,10 m3/m) durant l’apogée et la dissipation de l’orage, (b) l’exondation du gradin de plage pour générer une nouvelle terrasse côtière et (c) la migration de deux barres distales au large de la côte, laissant assez d’espace pour la mise en place d’une nouvelle barre. Les mécanismes de l’émersion, de la croissance et de la migration sont : (a) les contre-courants qui transportent les sédiments en suspension au large de la côte et (b) le transport vers la côte via la fréquence des vagues de gravité générées au début de l’orage et par les vagues d’infragravité subséquentes (au maximum de l’orage et durant sa dissipation). Le transport brut des sédiments est important, mais le résultat net correspond seulement à un léger transport vers le sud-ouest (direction historique du transit littoral). Ceci ne cause pas la création de la barre, mais peut contribuer aux apports sédimentaires nécessaires à sa croissance. Le mécanisme responsable de l’évolution des barres est le transport des sédiments par les vagues oscillatoires et les contre-courants

An Integrative Review of Youth Development Research in Selected United States Recreation Journals

Youth have been a focus of recreation and leisure programmers for over a century. During that time, assumptions have been made about the value of recreation for young people. More recently, a resurgence of interest has occurred related to positive youth development. The purpose of this paper is to describe the results of an integrative review done to examine research conducted with youth as a focal point in four prominent U.S. based recreation journals over the past 21 years (1985-2005). We sought to discern thematic patterns in topical areas and to review the approaches and methods used. Systematic content and thematic analyses of the Journal of Park and Recreation Administration, Therapeutic Recreation Journal, Leisure Sciences, and the Journal of Leisure Research were used. Findings showed that the research done about youth related to some aspect of recreation or leisure in the past ten years eclipsed what was done from 1985-1996. A variety of research methods were used with an equitable distribution of survey, literature reviews, experimental designs, and qualitative methods. The youth examined were primarily mixed gender groups, but boys were twice as likely to be studied as girls when single sex studies were undertaken. Most of the research was done with adolescent (ages 10-18 years) youth. Almost no research has been done in the recreation field related to early childhood (ages 1-4 years). The 11 major themes or topics that were studied in the past 21 years included: youth culture and leisure; leisure programming, treatment, and intervention; research, measurement, and evaluation; demographic factors; management, administration, and policy of youth programs; benefits of leisure for youth; youth and family leisure; recreation settings and leisure spaces; risk behaviors and delinquency; human development and developmental issues; and social behavior. In the integrative review, the focus on benefits and accountability relative to youth programs was obvious. The parallels between social change and youth development were also evident in the review. Recommendations for future research include more evidence-based work that links the program or intervention directly to youth development outcomes, as well as a focus on emerging topics such as physical inactivity and obesity in children, the influence of television and technology in general, youth sport, and the relationships youth have with nature and the outdoors

Sport Fan Team Identification Formation in Mid-Level Professional Sport

Team identification, the degree to which an individual feels psychologically linked to a team, has been a focal point in studies of sport fans and sport spectatorship (e.g. Fink et al., 2002; Jones, 1997; Wann & Branscombe, 1993; Wann & Dolan, 1994; Wann & Schrader, 1997). Although the development of team identification has been examined extensively in established sport markets, the purpose of this study is to assess the relationship between sport fan team identification and motivations for initially becoming a fan of a new mid-level professional sport in a new market. A convenience sample of spectators (N=351) at an American Arena Football League (AFL) game completed a survey designed to identify and measure this relationship. A simultaneous multiple regression analysis revealed significant and positive predictive value for team identification from the following reasons for becoming a fan: parents and/or family (β=.125, p\u3c .05), born and/or live in area (β=.210, p\u3c.001), players and/or coaches (β=.411, p=.001), and tailgating and party atmosphere (β=.123,

Temporal changes in nasopharyngeal carriage of Streptococcus pneumoniaeserotype 1 genotypes in healthy Gambians before and after the 7-valent pneumococcal conjugate vaccine

Streptococcus pneumoniae serotype 1 is one of the leading causes of invasive pneumococcal disease. However, this invasive serotype is hardly found in nasopharyngeal asymptomatic carriage and therefore large epidemiological studies are needed to assess the dynamics of serotype 1 infection. Within the context of a large cluster randomized trial conducted in rural Gambia to assess the impact of PCV-7 vaccination on nasopharyngeal carriage, we present an ancillary analysis describing the prevalence of nasopharyngeal carriage of pneumococcal serotype 1 and temporal changes of its more frequent genotypes. Nasopharyngeal swabs (NPS) were collected before PCV-7 vaccination (December 2003–May 2004) and up to 30 months after PCV-7 vaccination. The post-vaccination time was divided in three periods to ensure an equal distribution of the number of samples: (1) July 2006–March 2007, (2) April 2007–March 2008 and (3) April 2008–Feb 2009. S. pneumoniae serotype 1 were genotyped by MLST. Serotype 1 was recovered from 87 (0.71%) of 12,319 NPS samples collected. In the pre-vaccination period, prevalence of serotype 1 was 0.47% in both study arms. In the post-vaccination periods, prevalence in the fully vaccinated villages ranged between 0.08% in period 1 and 0.165% in period 2, while prevalence in partly vaccinated villages was between 0.17% in period 3 and 1.34% in period 2. Overall, four different genotypes were obtained, with ST3081 the most prevalent (60.71%), followed by ST618 (29.76%). ST3081 was found only in post-vaccination period 2 and 3, while ST618 had disappeared in post-vaccination period 3. Distribution of these major genotypes was similar in both study arms. Emergence of ST3081 and concomitant disappearance of ST618 may suggest a change in the molecular epidemiology of pneumococcal serotype 1 in this region. This change is not likely to be associated with the introduction of PCV-7 which lacks serotype 1, as it was observed simultaneously in both study arms. Future population-based epidemiological studies will provide further evidence of substantive changes in the pneumococcal serotype 1 epidemiology and the likely mechanisms

Youth Sport Market Segmentation with the Theory of Planned Behavior

Approximately half (54%) of all American youth between the ages of 6 -17 play in at least one organized sport (SGMA: Sporting Goods Manufacturers Association, 2004). By adulthood; however, only 15.4% of American adults report that they participate in the same organized sport (SGMA, 2004). While this deficit can be explained by an expansion of alternate activities available to adults or a lack of continued opportunities, there is evidence that adult participation in sports and other leisure activities is significantly influenced by the repertoire of activities they participated in as children (Scott & Willits, 1989; 1998). Sport managers wound benefit from a more thorough understanding of the reasons for initial involvement and the intentions to continue participation in guiding future retention efforts

A trial of intermittent preventive treatment and home-based management of malaria in a rural area of The Gambia

BACKGROUND: Individual malaria interventions provide only partial protection in most epidemiological situations. Thus, there is a need to investigate whether combining interventions provides added benefit in reducing mortality and morbidity from malaria. The potential benefits of combining IPT in children (IPTc) with home management of malaria (HMM) was investigated. METHODS: During the 2008 malaria transmission season, 1,277 children under five years of age resident in villages within the rural Farafenni demographic surveillance system (DSS) in North Bank Region, The Gambia were randomized to receive monthly IPTc with a single dose of sulphadoxine/pyrimethamine (SP) plus three doses of amodiaquine (AQ) or SP and AQ placebos given by village health workers (VHWs) on three occasions during the months of September, October and November, in a double-blind trial. Children in all study villages who developed an acute febrile illness suggestive of malaria were treated by VHWs who had been taught how to manage malaria with artemether-lumefantrine (Coartem™). The primary aims of the project were to determine whether IPTc added significant benefit to HMM and whether VHWs could effectively combine the delivery of both interventions. RESULTS: The incidence of clinical attacks of malaria was very low in both study groups. The incidence rate of malaria in children who received IPTc was 0.44 clinical attacks per 1,000 child months at risk while that for control children was 1.32 per 1,000 child months at risk, a protective efficacy of 66% (95% CI -23% to 96%; p = 0.35). The mean (standard deviation) haemoglobin concentration at the end of the malaria transmission season was similar in the two treatment groups: 10.2 (1.6) g/dL in the IPTc group compared to 10.3 (1.5) g/dL in the placebo group. Coverage with IPTc was high, with 94% of children receiving all three treatments during the study period. CONCLUSION: Due to the very low incidence of malaria, no firm conclusion can be drawn on the added benefit of IPTc in preventing clinical episodes of malaria among children who had access to HMM in The Gambia. However, the study showed that VHWs can successfully combine provision of HMM with provision of IPTc
