Positional differences of physical peak intense periods in Swedish elite football : A pilot study of under 19 and first team players / Positionsskillnader vid den mest fysiskt intensiva perioden i svensk elitfotboll : En pilotstudie av ungdomsspelare och seniorspelare

Eriksson, Adam January 2024 (has links)
Syfte: Syftet med denna studie är att med hjälp av multivariata parametrar undersöka skillnader i fysisk extern belastning under den mest intensiva perioden (MIP) av match för spelare på ungdomselit och seniornivå samt att identifiera eventuella skillnader mellan positioner och halvlekar.Metod: En kvantitativ retrospektiv studie tillämpades, där spelare från ett seniorlag (SEN)spelandes i högsta divisionen i Sverige samt fotbollsspelare från ett ungdomselitlag (U19)från samma klubb spelades i näst högsta divisionen för åldersgruppen deltog i studien. Fysisk extern belastning mättes med hjälp av Global Positioning System (GPS). MIP analyserades utifrån spelares taktiska utgångsposition och med hjälp av multivariata parametrar. Rullande medelvärden användes för analys av 1-min MIP.Resultat: SEN täckte signifikant längre distans under den mest intensiva 1-mintusperioden av match jämfört med U19 (SEN 140 ± 22,3 m; U19 120 ± 24,1 m, p < 0.001). Vid jämförelse mellan positioner täcker SEN-Lateral längre distanser än U19-Lateral under mest intensiva 1-mintusperioden av MIP-kinematik (135 ± 23.5 m vs 104 ± 40.3 m, p = 0.015).Slutsats: Sammanfattningsvis konfirmerar denna studie en skillnad av den mest intensiva 1-minuters perioden för senior- och ungdomsspelare för MIPk. Studien visar att seniorspelare positionerade lateral på planen täcker längre distanser under MIPk jämfört med U19 på samma position. Praktiker bör beakta dessa skillnader i sina träningsupplägg för att kunna förbereda ungdomsspelare för de fysiska krav som ses i seniormiljön / Aim: The present study aimed to investigate differences in physical external load during the most intense period (MIP) of match play for youth and senior player and to indentify possible differences between positions and halves, with multivariate parameters. Method: A quantitative retrospective study was applied, players from a senior team playing in the highest division in Sweden participated in the study as well as football players from a youth elite team from the same club playing in the second highest division for the age group. Physical external load was measured using Global Positioning System (GPS). MIP was analyzed based on players' initial tactical position and using multivariate parameters. Rolling averages were used to analyze 1-min MIP.Results: SEN covered significantly longer distances during the most intense 1-min period of the match compared to U19 (SEN 140 ± 22,3 m; U19 120 ± 24,1 m, p < 0.001). When comparing between positions, SEN-Lateral covers longer distances than U19-Lateral during the most intense 1-minute period of the MIPk (135 ± 23.5 m vs 104 ± 40.3 m, p = 0.015).Conclusions: In conclusion, this study confirms a difference in the most intense 1-minute period for senior and youth players for MIPk. The study shows that senior players positioned laterally on the pitch cover longer distances during MIPk compared to U19-Lateral. Practitioners should consider these differences in their training programmes in order to prepare youth players for the physical demands seen in the senior environment.

Specifika počítačem podporovaného překladu z němčiny do češtiny / CAT Tools in German - Czech Translation

Handšuhová, Jana January 2013 (has links)
Abstract This thesis handles special translation software, the mastery of which is becoming one of the basic requirements of successful translation work. The theoretical part describes the historical development, classification and main functions of translation memory systems. The thesis will further attempt to determine the criteria for the effective use of CAT tools and explore the text types and sorts for which the translation memory systems are most commonly used in the translation process. The functional view of the language-based text typology and the principles on which the translation memory systems work will also be handled. The practical part compares the result of a translation process (translation as a product) with and without CAT tools. The corpus of parallel texts (original translation) will be subjected to a translation analysis. This analysis concludes the levels which are affected by differences between translations made with and without CAT tools. The differences in the actual translation process with and without CAT tools which are not empirically verifiable will be analysed based on a survey conducted amongst translators. Then, the empirical part of the findings are summarized and systemized. The last chapter deals with the expected development in the translation market, the...

Development of a Slab-on-Girder Wood-concrete Composite Highway Bridge

Lehan, Andrew Robert 23 July 2012 (has links)
This thesis examines the development of a superstructure for a slab-on-girder wood-concrete composite highway bridge. Wood-concrete composite bridges have existed since the 1930's. Historically, they have been limited to spans of less than 10 m. Renewed research interest over the past two decades has shown great potential for longer span capabilities. Through composite action and suitable detailing, improvements in strength, stiffness, and durability can be achieved versus conventional wood bridges. The bridge makes use of a slender ultra-high performance fibre-reinforced concrete (UHPFRC) deck made partially-composite in longitudinal bending with glued-laminated wood girders. Longitudinal external unbonded post-tensioning is utilized to increase span capabilities. Prefabrication using double-T modules minimizes the need for cast-in-place concrete on-site. Durability is realized through the highly impermeable deck slab that protects the girders from moisture. Results show that the system can span up to 30 m while achieving span-to-depth ratios equivalent or better than competing slab-on-girder bridges.

Absent Presence: Women in American Gangster Narrative

Coccimiglio, Carmela 03 October 2013 (has links)
Absent Presence: Women in American Gangster Narrative investigates women characters in American gangster narratives through the principal roles accorded to them. It argues that women in these texts function as an “absent presence,” by which I mean that they are a convention of the patriarchal gangster landscape and often with little import while at the same time they cultivate resistant strategies from within this backgrounded positioning. Whereas previous scholarly work on gangster texts has identified how women are characterized as stereotypes, this dissertation argues that women characters frequently employ the marginal positions to which they are relegated for empowering effect. This dissertation begins by surveying existing gangster scholarship. There is a preoccupation with male characters in this work, as is the case in most gangster texts themselves. This preoccupation is a result of several factors, such as defining the genre upon criteria that exclude women, promoting a male-centred canon as a result, and making assumptions about audience composition and taste that overlook women’s (and some women characters’) interest in gangster texts. Consequently, although the past decade saw women scholars bringing attention to female characters, research on male characters continues to dominate the field. My project thus fills this gap by not only examining the methods by which women characters navigate the male-dominated underworld but also including female-centred gangster narratives. Subsequent chapters focus on women’s predominant roles as mothers, molls, and wives as well as their infrequent role as female gangsters. The mother chapter demonstrates how the gangster’s mother deploys her effacement as an idealized figure in order to disguise her transgressive machinations (White Heat, The Sopranos). The moll chapter examines how this character’s presence as a reforming influence for the male criminal is integral to the earliest narratives. However, a shift to male relationships in mid- to late-1920s gangster texts transforms the moll’s status to that of a moderator (Underworld, The Great Gatsby). On the other hand, subsequent non-canonical texts feature molls as protagonists and illustrate the potential appeal of the gangster figure to women spectators (Three on a Match). Subsequently, the wife chapter explores texts that show presence is manifested in the wife’s cultivation of a traditional family image, while absence is evident in her exposure of this image as a façade via her husband’s activities (The Godfather, Goodfellas). In the following female gangster chapter, I examine how gender functions to render this rare character a literal absent presence such that she is inconceivable as a subject (Lady Scarface, Lady Gangster). Expanding upon this examination of gender, a final chapter on the African-American female gangster (in Set It Off and The Wire) explores how sexuality, race, and female—as well as “gangsta”—masculinity intersect to create this character’s simultaneous hypervisibility and invisibility. By examining women’s roles that often are overlooked in a male-dominated textual type and academic field, this dissertation draws scholarly attention to the ways that peripheral status can offer a stealthy locus for self-assertion.

Evaluation von KIR-Liganden Inkompatibilität bei unverwandten Knochenmark-/ Stammzelltransplantationen

Martin, Hilmar 26 July 2005 (has links)
We performed a retrospective study in 185 patients with myelogenous leukemias who had received hematopoietic cells from unrelated donors. The aim of this study was to answer the question wether the benefit of KIR ligand incompatibility seen in haploidentical tranplantations can also be seen using unrelated donors. We could not detect a significant difference in survival between patients with a KIR ligand incompatibility and those with either fully matched or partially mismatched unrelated donors in this patient cohort. / In der Therapie von Leukämien ist die Knochenmark- bzw. Stammzelltransplantation eine tragende Säule. Für den Transplantationserfolg ist eine Übereinstimmung der Haupthistokompatibilitätsantige (HLA-Antigene der Klassen I und II) zwischen Spender und Empfänger von zentraler Bedeutung. Diese Notwendigkeit ergibt sich aus der sogenannten MHC-Restriktion in der T-Zellrezeptorerkennung. Ob auch NK-Zellrezeptoren und deren Liganden in der Spenderauswahl berücksichtigt werden sollten, ist bisher unzureichend untersucht. Insbesondere trifft das für die KIR-Rezeptoren zu, die wie die T-Zellrezeptoren ebenfalls HLA-Antigene als Liganden besitzen. Velardi et al. haben 2002 erstmalig gezeigt, daß in der Therapie myeloischer Leukämien die Transplantation von Blutstammzellen verwandter Spender mit KIR-Liganden-Inkompatibilität von klinischem Vorteil ist. Ob KIR-Liganden-Inkompatibilität auch bei Knochenmark-/ Stammzelltransplantationen Unverwandter Bedeutung erlangen könnte, war zu Studienbeginn offen und blieb auch infolge diskrepanter Untersuchungsergebnisse von verschiedenen Arbeitsgruppen im Verlauf der Studie widersprüchlich. Im Rahmen dieser Arbeit wurde diese Fragestellung, die auch Teil einer internationalen Studie war, an 185 Spender-Empfänger-Paaren retrospektiv untersucht. Dabei wurde bei den Paaren einerseits die KIR-Liganden-Kompatibilität auf der Grundlage der HLA-C-Supertypen erschlossen (nach Velardi et al.). Andererseits konnte sie im internationalen Studienprogramm direkt aus dem KIR-Genotyp des Spenders und dem HLA-C-Supertyp des Empfängers ermittelt werden. Die Untersuchungen ergaben folgende Resultate: bei Vorliegen von KIR-Liganden-Inkompatibilität hat die Verwendung von ATG als Bestandteil der GvHD-Prophylaxe keinen Einfluß auf das klinische Ergebnis. Die Vermutungen von Giebel et al. wurden damit nicht gestützt. Die Bestimmung des KIR-Liganden-Status mit Hilfe der Rückschlußmethode allein aus dem HLA-Typ ist unzuverlässig. Für eine exakte Differenzierung ist die gleichzeitige KIR-Genotypisierung erforderlich. KIR-Liganden-Inkompatibilität ist bei unverwandten Knochenmark-/ Stammzelltransplantationen nicht von klinischem Vorteil. Auch ein gezieltes Aussuchen HLA-C-inkompatibler Spender auf der Grundlage einer KIR-Genotypisierung stellt derzeit keine therapeutische Option dar.

Avancées en médecine transfusionnelle féline : de l’optimisation du prélèvement à la découverte de nouveaux antigènes érythrocytaires

Binvel, Marie 07 1900 (has links)
La médecine transfusionnelle féline a connu une croissance exponentielle au cours des dix dernières années. La découverte du système de groupes sanguins AB et la meilleure compréhension des mécanismes d’incompatibilité donneur-receveur, ainsi que le développement de systèmes de collecte adaptés au chat et de techniques de typage sanguin au chevet du patient ont permis d’améliorer la sécurité des transfusions. Notre travail s’est intégré dans cette volonté d’optimiser la sécurité des transfusions sanguines chez le chat en se concentrant sur deux aspects différents : le prélèvement de sang et les antigènes érythrocytaires à l’origine d’incompatibilités donneur-receveur non expliquées par le système AB. Dans un premier temps, un système de collecte de sang adapté au chat a été fabriqué afin de permettre un prélèvement fermé et autoriser le stockage des produits sanguins. Ce système a été comparé à un système ouvert composé de seringues. Le système fermé apparaît adapté au prélèvement de sang car aucune différence significative n’a été enregistrée dans les paramètres vitaux des donneurs après le prélèvement, le succès du prélèvement, ou la qualité du produit sanguin en termes de contamination bactérienne et d’hémolyse, entre les deux systèmes. Le net avantage du système fermé est qu’il assure un temps de prélèvement plus rapide que le système ouvert. Dans un second temps, en réalisant des tests de compatibilité chez 258 chats de type A, nous avons montré que la probabilité de détecter des incompatibilités entre deux chats de groupe A sélectionnés aléatoirement était de 3.9 %, et que 7 % des chats de groupe A présentaient des allo-anticorps naturels extérieurs au système AB. Sept des 18 allo-anticorps naturels détectés ont été utilisés comme réactifs lors d’un typage sanguin extensif. Les analyses sur l’accord des résultats du typage obtenus avec les différents réactifs ont permis d’identifier cinq nouveaux antigènes érythrocytaires félins différents, nommés FEA 1 à FEA 5 (pour feline erythrocyte antigen), dont l’hérédité, la prévalence, la distribution géographique et par race, ainsi que l’immunogénicité restent encore à déterminer. / Feline transfusion medicine has grown exponentially over the past decade. The discovery of the AB blood group system and the better understanding of the mechanisms of donor-receiver incompatibility, as well as the development of cat-friendly collection systems and bedside blood typing techniques have improved transfusion safety. Our work has been part of this effort to optimize the safety of blood transfusions in cats by focusing on two different aspects: blood collection and red blood cell antigens that cause donor-recipient incompatibilities unexplained by the AB system. First, a blood collection system adapted to the cat was manufactured to allow collection in a closed-system and storage of blood products. This system was compared to an open system consisting of syringes. The closed system appeared well-adapted for feline blood collection because no significant difference was found in the vital parameters of the donors after collection, the success of the collection, or the quality of the blood product in terms of bacterial contamination and hemolysis. The distinct advantage of the closed system was that it provided a shorter duration of collection than the open system. Secondly, based on the systematic crossmatches of 258 cats, we showed that the probability of detecting incompatibilities by randomly crossmatching two type A cats was 3.9 %, which resulted in at least 7 % of type A cats having naturally occurring alloantibodies outside the AB blood group system. Seven of the 18 detected naturally occurring alloantibodies were used as reagents in an extensive blood typing. Comparison of the results obtained from this extensive blood typing supports the existence of five, presumably different, new feline erythrocyte antigens, named FEA 1 to FEA 5, whose mode of inheritance, geographical and breed distribution, frequency and immunogenicity have yet to be determined.

Selection of industrial and organisational psychology master's students: exploring the validity of applied psychometric measures

Olivier, Karina Cornelia 10 1900 (has links)
The objective of this study was to investigate how well the academic performance of the Industrial and Organisational Psychology master’s students at a research institution can be predicted through psychometric measures. A non-experimental design was used in this empirical study. The sample consisted of one hundred and thirty-three IO Psychology master’s students over a five-year period. The secondary data for this research originated from the students completing the Graduate Verify Ability tests as well as the Occupational Personality Questionnaire, which are psychometric measures that form part of the selection. Both psychometric measures load onto the Person Job Match competencies. A theoretical relationship could be found between the Ability tests and academic success as well as the PJM competencies that included weighted scores from both psychometric measures. The empirical relationships, therefore, proved that the ability tests have the strongest predictive ability for academic success. / Industrial and Organisational Psychology / M. Com.
