Positive Youth Development (PYD) research has started to shift focus onto how different internal factors such as temperament, dispositions, and/or personality characteristics could influence levels of PYD for youth participating is organized sport. The purpose of this study is to examine how different goal profiles, specifically categorized by diverse levels of task and ego orientation, can influence levels of PYD in an organized youth sport setting. One hundred youth sport participants (mean age = 16.8) completed the short form Youth Experiences Survey for Sport (short form YES-S; Sullivan et al., 2013) to measure PYD, as well as the Task and Ego Orientation in Sport Questionnaire (TEOSQ; Duba 1989) to assess each athlete’s goal profile. A TwoStep Cluster Analysis was used to classify each individual’s personal goal profile into 3 statistically different cluster groupings. Results indicated significant interaction between the PYD outcome factor of Initiative vs. Clusters [F(2,95)= 10.86, p < 0.001, p2= 0.19] as well as Goal Setting vs. Clusters [F(2,95)= 3.95, p < 0.05, p2= 0.08]. Post-hoc analyses provided results that suggest that those athletes who are more task oriented have fostered more positive outcomes from sport, therefore having more goal setting skills and initiative.

Dans les services de première ligne, la majorité des personnes atteintes de dépression souffrent également d’autres maladies chroniques comorbides. Offrir des soins de haute qualité à ces patients représente un défi important pour les intervenants en première ligne ainsi que pour le système de santé. Il y a des raisons de croire que les contextes organisationnels dans lesquels les intervenants pratiquent ont une influence importante sur les soins. Cependant, peu d’études ont examiné directement la façon dont les caractéristiques des cliniques facilitent ou entravent les soins offerts aux patients atteints de dépression et de différents types de maladies chroniques comorbides. L’objectif général de ce projet de recherche était donc de mieux comprendre comment différentes caractéristiques des cliniques de première ligne influencent la qualité des soins pour la dépression chez des patients ayant différents profils de comorbidité. La thèse comporte deux études. Tout d'abord, nous avons effectué une revue systématique examinant les relations entre la comorbidité physique chronique et la qualité des soins pour la dépression dans les services de première ligne afin de clarifier la nature de ces relations et d’identifier les facteurs qui pourraient influer sur ces relations. Ensuite, nous avons effectué une étude aux méthodes mixtes ayant deux volets : (a) un volet quantitatif examinant les relations entre la qualité des soins pour la dépression, les profils de comorbidité des patients, et les caractéristiques des cliniques de première ligne par le biais d’analyses de régression multiniveaux de données issues de deux enquêtes, et (b) un volet qualitatif basé sur une étude de cas explorant les perceptions des professionnels des services de première ligne sur les facteurs organisationnels pouvant influencer la qualité des soins offerts aux patients souffrant de dépression et d’autres maladies chroniques comorbides. Les résultats de ces études ont montré que, bien que la qualité des soins de la dépression en soins primaires soit sous-optimale, certains sous-groupes de patients dépressifs sont plus à risque que d’autres de recevoir des soins pour la dépression inadéquats, notamment des patients ayant uniquement des comorbidités chroniques physiques. Cependant, plusieurs caractéristiques des cliniques de première ligne semblent faciliter l’offre de soins de qualité aux patients atteints de dépression et de maladies chroniques comorbides : les normes et les valeurs liées au travail d'équipe et le soutien mutuel, l'accès au soutien des professionnels ayant une expertise en santé mentale, l’utilisation des algorithmes de traitement et d’autres outils d’aide à la décision pour la dépression, et l’absence d’obstacles liés aux modèles de rémunération inadéquats. Une des façons dont ces caractéristiques favorisent la qualité est en facilitant la circulation des connaissances dans les cliniques de première ligne. Nos résultats suggèrent que des interventions organisationnelles ciblées sont nécessaires pour améliorer la qualité des soins pour la dépression que reçoivent les patients ayant des maladies chroniques comorbides. Ces interventions peuvent viser différents domaines organisationnels (ex : caractéristiques structurelles/stratégiques, sociales, technologies et épistémiques) mais doivent aussi prendre en compte comment les éléments de chaque domaine interagissent et comment ils pourraient influencer les soins pour des patients ayant des profils de comorbidité différents.

Compact-range radar backscatter measurements are taken of aircraft scale models. In addition, computer software is used to predict the RCS of the aircraft. Synthetic down-range profiles formed from the two sources of backscatter data are compared and visualized in an innovative manner. Similar discrimination rates between the two aircraft are obtained on data from both source

A total of eighty-one Escherichia coli isolates belonging to forty-three different serotypes including several pathogenic strains such as enterotoxigenic E. coli (ETEC), enterohaemorrhagic E. coli (EHEC), enteropathogenic E. coli (EPEC) and uropathogenic E. coli (UPEC) isolated from Cochin estuary between November 2001 and October 2002 were tested against twelve antibiotics to determine the prevalence of multiple antibiotic resistance (MAR) and antimicrobial resistance profiles as a measure of high risk source of contamination. The results revealed that more than 95% of the isolates were multiple antibiotic resistant (resistant to more than three antibiotics). The MAR indexing of the isolates showed that all these strains originated from high risk source of contamination. The incidence of multiple antibiotic resistant E. coli especially the pathogenic strains in natural waters will pose a serious threat to human population

The median of a profile = (u1, . . . , uk ) of vertices of a graph G is the set of vertices x that minimize the sum of distances from x to the vertices of . It is shown that for profiles with diameter the median set can be computed within an isometric subgraph of G that contains a vertex x of and the r -ball around x, where r > 2 − 1 − 2 /| |. The median index of a graph and r -joins of graphs are introduced and it is shown that r -joins preserve the property of having a large median index. Consensus strategies are also briefly discussed on a graph with bounded profiles.

The median problem is a classical problem in Location Theory: one searches for a location that minimizes the average distance to the sites of the clients. This is for desired facilities as a distribution center for a set of warehouses. More recently, for obnoxious facilities, the antimedian was studied. Here one maximizes the average distance to the clients. In this paper the mixed case is studied. Clients are represented by a profile, which is a sequence of vertices with repetitions allowed. In a signed profile each element is provided with a sign from f+; g. Thus one can take into account whether the client prefers the facility (with a + sign) or rejects it (with a sign). The graphs for which all median sets, or all antimedian sets, are connected are characterized. Various consensus strategies for signed profiles are studied, amongst which Majority, Plurality and Scarcity. Hypercubes are the only graphs on which Majority produces the median set for all signed profiles. Finally, the antimedian sets are found by the Scarcity Strategy on e.g. Hamming graphs, Johnson graphs and halfcubes

Glass fiber reinforced polymer (GFRP) rebars have been identified as an alternate construction material for reinforcing concrete during the last decade primarily due to its strength and durability related characteristics. These materials have strength higher than steel, but exhibit linear stress–strain response up to failure. Furthermore, the modulus of elasticity of GFRP is significantly lower than that of steel. This reduced stiffness often controls the design of the GFRP reinforced concrete elements. In the present investigation, GFRP reinforced beams designed based on limit state principles have been examined to understand their strength and serviceability performance. A block type rotation failure was observed for GFRP reinforced beams, while flexural failure was observed in geometrically similar control beams reinforced with steel rebars. An analytical model has been proposed for strength assessment accounting for the failure pattern observed for GFRP reinforced beams. The serviceability criteria for design of GFRP reinforced beams appear to be governed by maximum crack width. An empirical model has been proposed for predicting the maximum width of the cracks. Deflection of these GFRP rebar reinforced beams has been predicted using an earlier model available in the literature. The results predicted by the analytical model compare well with the experimental data

This paper gives the details of flexure-shear analysis of concrete beams reinforced with GFRP rebars. The influence of vertical reinforcement ratio, longitudinal reinforcement ratio and compressive strength of concrete on shear strength of GFRP reinforced concrete beam is studied. The critical value of shear span to depth ratio (a/d) at which the mode of failure changes from flexure to shear is studied. The fail-ure load of the beam is predicted for various values of a/d ratio. The prediction show that the longitudinally FRP reinforced concrete beams having no stirrups fail in shear for a/d ratio less than 9.0. It is expected that the predicted data is useful for structural engineers to design the FRP reinforced concrete members.

Kerala, a classic ecotourism destination in India, provides significant opportunities for livelihood options to the people who depend on the resources from the forest and those who live in difficult terrains. This article analyses the socio-demographic, psychographic and travel behavior patterns and its sub-characteristics in the background of foreign and domestic tourists. The data source for the article has been obtained from a primary survey of 350 randomly chosen tourists, 175 each from domestic and foreign tourists, visiting Kerala’s ecotourists destinations during August-December 2010-11. Several socio-demographic, psychographic and life style factors have been identified based on the inference from field survey. There is considerable divergence in most of the factors identified in the case of domestic and international tourists. Post-trip attributes like satisfaction and intentions to return show that the ecotourism destinations in Kerala have significant potential that can help communities in the region.
