Objective: To determine if undergraduate athletic training students enrolled in an athletic training education program (ATEP) and participating in a clinical assignment have burnout and if so, the possible causes. Design and Setting: All undergraduate athletic training students enrolled in a clinical education course were surveyed twice in an eight week period. The surveys were given during the fourth week and the twelfth week of the winter 2006 semester. As part of the survey, each participant also answered eight demographic/status questions for correlation purposes. Subjects: Fifty-one undergraduate athletic training students in a western United States university's accredited ATEP served as subjects for this study. Measurements: Data was analyzed using analysis of covariance with categorical independent variables and continuous covariants. Emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA) were scored in accordance with the MBI-HSS. Post hoc testing was done when interactions/effects were significant at the p = .05 level. Dependent variables consisted of the three subsets of burnout (EE, DP, and PA). Results: Overall mean scores demonstrated a moderate level (17.0) of EE, low levels (5.7) of DP, and moderate level (38.0) of PA. Fourth (+) semester students reported high DP levels (13.3) and high levels of EE (30.9). Semester effect (p = pre- 0.0001; post- 0.007), marital/serious relationship status by gender interaction (p = pre- 0.008; post- 0.02) and semester by gender interaction (p = pre- 0.0017; post- 0.005) all had an effect on EE for both testing times. For DP, marital/serious relationship status by semester interaction (p = pre- 0.0121; post- 0.003), semester (p = pre- 0.0001; post- 0.0003), and semester by gender interaction (p = pre- 0.0001; post- 0.0001) were significant interactions/effects for both pre and post-tests. Conclusions: This study showed that with moderate PA, low DP, and moderate EE undergraduate athletic training students, demonstrated a moderate degree of burnout from their clinical assignments. The expectations of the ATEP appear to have a cumulative effect which is evidenced in the fourth (+) semester showing a high/average degree of burnout.

Syftet med studien är att undersöka hur Lpo 94 påverkat lärarens yrkesroll i Idrott och hälsa. Undersökningsgruppen består av åtta stycken lärare i södra Skåne. Huvudfrågeställningen lyder enligt följande; Vad innebar Lpo 94 för lärarna i Idrott och Hälsas arbete? Frågan följs även upp av tre stycken underfrågor; Hur upplever lärarna att tolkningen av målen för Lpo 94 förändrats från dess intåg fram till idag? Vad innebar arbetslagen och den förändrade organisationen för lärarna i Idrott och Hälsas arbete? Var lärarna i Idrott och Hälsa redo för förändringen? Detta görs genom en kvalitativ intervjumetod. Resultatet visar på att arbetet med Lpo 94 gått väldigt långsamt och fortfarande inte efterföljs på många skolor. Detta kan till viss del bero på den ökade arbetsbördan som lärarna i Idrott och hälsa upplever. Lpo 94 innebar en ny organisation som genomsyrades av nya samarbetsformer i form av arbetslag, mentorskap och andra former av tidskrävande merarbete. Idrottsämnet och dess nya utformning var inte anpassat för de organisatoriska förändringar som skolan genomgick. Vidare diskuteras och analyseras hur de olika lärarna hanterar det nya uppdraget samt vad de olika värderingarna och handlandena kan grunda sig i. I studien behandlas också ämnet Idrott och hälsa och dess legitimitet i förhållande till andra ämnen samt vilka andra faktorer som påverkat idrottslärarnas arbete efter införandet av Lpo 94. / The aim of this study is to show how the Lpo 94 has affected the teachers professional role in Physical education. Eight teachers from the south of Skåne were used as informants. The main question asked is; What impact did the Lpo 94 have to teachers of Physical education? The main question is also monitored by three subqueries: How do the teachers in Physical education feel that the interpretation of the objectives for Lpo 94 have changed from its entrance until today? What did the “work team” and the changing organization influence the teachers in Physical education? Were the PE teachers ready for the change?A qualitative interview method is used and the results show that the progress of Lpo 94 has gone very slowly and that it still hasen´t been enforced in many schools. According to the PE teachers there are several reasons to why it hasen´t been enforced but a common denominator is the increased workload. Lpo 94 meant new organizations, new cooperation in teams, mentoring and other forms of time-consuming burdens. Physical education and its new design were not adapted to the organizational changes that the school underwent at the same time. Further discussed and analyzed in the study is how the various teachers handled the new assignment and what their different values and actions can be based on. The study also deals with Physical Education and its legitimacy in terms of other school subjects and other factors that have affected the PE teachers work after the introduction of Lpo 94.

This thesis consists of two papers. The first paper is a study of the structure of the k-assignment polytope, whose vertices are the m x n (0; 1)-matrices with exactly k 1:s and at most one 1 in each row and each column. This is a natural generalisation of the Birkhoff polytope and many of the known properties of the Birkhoff polytope are generalised. Two equivalent representations of the faces are given, one as (0; 1)-matrices and one as ear decompositions of bipartite graphs. These tools are used to describe properties of the polytope, especially a complete description of the cover relation in the face lattice of the polytope and an exact expression for the diameter. The second paper studies the edge-product space Є(X) for trees on X. This space is generated by the set of edge-weighted finite trees on X, and arises by multiplying the weights of edges on paths in trees. These spaces are closely connected to tree-indexed Markov processes in molecular evolutionary biology. It is known that Є(X) has a natural CW-complex structure, and a combinatorial description of the associated face poset exists which is a poset S(X) of X-forests. In this paper it is shown that the edge-product space is a regular cell complex. One important part in showing that is to conclude that all intervals [Ô, Г], Г Є S(X), have recursive coatom orderings.

Elevators are used every day and that puts expectations on how fast an elevator can handle passenger requests. This report aims to describe different elevator assignment algorithms for Elevator Supervisory Group Control (ESGC) systems and compare them to each other, with an emphasis on the delay time. To research the field of ESGC systems four different algorithms were chosen and implemented: Simple control, Zone control, Collective control and Fuzzy control. The algorithms were also chosen in such a way that their strategies differentiated from each other to some degree. The algorithms were then tested under conditions similar to an office building with interfloor traffic. Five different test cases demonstrated the performance and behavior of the strategies in varying environments. While Collective control proved to have a consistent performance, the more calculated Fuzzy control had the best statistical results. Zone control was the most affected by challenging conditions such as high traffic in the building. Simple control divided the workload equally, but did not make suitable elevator assignments. / Hissar används varje dag och det skapar förväntningar på hur snabbt en hiss kan hantera passagerarresor. Den här rapporten ämnar beskriva olika hisstilldelnings-algoritmer för Elevator Supervisory Group Control (ESGC) system och även jämföra dessa med varandra, med tyngdpunkt på fördröjningstiden. För att undersöka ämnesområdet ESGC system valdes och implementerades fyra olika algoritmer: Simple control, Zone control, Collective control and Fuzzy control. Algoritmerna valdes ut på ett sätt, så att deras strategier skilde sig åt till en viss grad. De testades sedan i en miljö som efterliknar ett kontorshus med trafik mellan våningar. Fem olika testfall demonstrerade prestationer och beteenden hos strategierna i varierande miljöer. Collective control hade bevisligen konsekvent prestation, medan den kalkulerande Fuzzy control åstadkom de bästa statistiska resultaten. Zone control påverkades i högst grad av utmanande förhållanden, såsom hög trafik i byggnaden. Simple control delade upp arbetsmängden jämnt mellan hissarna, men lyckades inte med att göra lämpliga hisstilldelningar.

The morphoscopic traits used to assign the term Hispanic to a skeleton constitute mainly a mixture of characteristics that have been assigned by anthropologists to Asian and Caucasian ancestry groups. Therefore, the morphological characteristics for the population termed Hispanic are not well defined. The aim of this study is to conduct a biodistance analysis of skeletons of Hispanic ancestry from Puerto Rico. The purpose of this is to assess how similar their morphoscopic characteristics are to other populations termed Hispanic as well as populations termed Asian. The analysis will be conducted by taking craniometric measurements. Pre-Colombian as well as modern skeletons from Puerto Rico will be examined and compared to other Hispanic as well as Asian populations that form part of the Forensic Anthropology Data Bank (FDB). Results from this study will help characterize Hispanic skeletal variation. In addition, this study will discuss the complexities of Hispanic classification in forensic anthropological contexts.

Efficient multi-dimensional assignment algorithms and their application in multi-frame tracking / In this work, we propose a novel convex dual approach to the multidimensional dimensional assignment problem, which is an NP-hard binary programming problem. It is shown that the proposed dual approach is equivalent to the Lagrangian relaxation method in terms of the best value attainable by the two approaches. However, the pure dual representation is not only more elegant, but also makes the theoretical analysis of the algorithm more tractable. In fact, we obtain a su cient and necessary condition for the duality gap to be zero, or equivalently, for the Lagrangian relaxation approach to nd the optimal solution to the assignment problem with a guarantee. Also, we establish a mild and easy-to-check condition, under which the dual problem is equivalent to the original one. In general cases, the optimal value of the dual problem can provide a satisfactory lower bound on the optimal value of the original assignment problem. We then extend the purely dual formulation to handle the more general multidimensional assignment problem. The convex dual representation is derived and its relationship to the Lagrangian relaxation method is investigated once again. Also, we discuss the condition under which the duality gap is zero. It is also pointed out that the process of Lagrangian relaxation is essentially equivalent to one of relaxing the binary constraint condition, thus necessitating the auction search operation to recover the binary constraint. Furthermore, a numerical algorithm based on the dual formulation along with a local search strategy is presented. Finally, the newly proposed algorithm is shown to outperform the Lagrangian relaxation method in a number of multi-target tracking simulations. / Thesis / Doctor of Philosophy (PhD)
