Title: The influence of age, gender and movement activity on the reaction abilities of lower limbs. Objectives: The main objective of this dissertation was to find the reaction abilities of pubescent's (aged 10 - 15years) lower limbs on the basis of age, gender and movement activity. The further aim was to determine the pubescence period (age) when the most noticeable decrease of the visual disjunctive motor response time of lower limbs occurs. Methods: 214 boys and girls aged 10-15 years (157.8 ± 10.8 cm; 47.2 ± 10.7 kg) participated in this research. Simple, choice and disjunctive reaction time of lower limbs was measured through the Fitro Agility Check test. The results processing, including statistical procedures, was carried out using the Matlab (MathWorks, Inc.) programming environment, an IBM SPSS Statistics 22. Three-way ANOVA and Tukey post-hoc tests (α=0.05) were used to determine the individual parameters connection. Results: With increasing age, year over year, we found important differences and reaction time decreases of all types of reaction speeds. Testing brings to light the fact that the most noticeable decrease of both selection and disjunctive reaction time of lower limbs are between groups of 11 year olds (11.00-11.99) and 12 year olds (12.00-12.99). The most noticeable decrease...

I en mer komplex och föränderlig värld har organisationer svårt att hänga med och tillräckligt snabbt ta vara på möjligheter, hantera utmaningar samt leva upp till förändringar i kundernas krav. De behöver därför öka sin förmåga att snabbare anpassa sig till förändring, något som benämns som business agility. För att bättre kunna hantera snabba förändringar har organisationer börjat arbeta enligt agila metoder, men dessa togs fram med enstaka team som förebild och är inte tänkta att hantera de utmaningar som uppstår när många team ska samarbeta i större organisationer. För att stora organisationer ska uppnå business agility behöver de skala upp de agila metoderna, denna organisationsförändring brukar benämnas som agil transformation. Till sin hjälp har de storskaliga agila ramverk. Det finns få fallstudier av agil transformation och tillämpningen av storskaliga agila ramverk i olika miljöer, i synnerhet i stora organisationer som är hårt reglerade och inom offentlig sektor. I de undersökningar och rapporter som finns är många utmaningar och framgångsfaktorer direkt eller indirekt koppling till ledarskapsfrågor men det finns begränsat med forskning om erfarenheter hos ledare, vilka är de personer som förväntas leda organisationsförändringen. Några av de största utmaningarna som har rapporterats är förändringsmotstånd hos medarbetare och en organisationskultur i strid med agila värderingar. Några av framgångsfaktorerna är stöd från ledning, kommunikation, transparens och att ökat kunnande i agil praxis. Syfte med denna studie är att från ett ledarskapsperspektiv undersöka en agil transformation med stöd av ett storskaligt agilt ramverk hos en myndighet. Den teoretiska referensramen innefattar teorier som har betydelse för förståelsen av business agility, agil transformation och lean-agilt ledarskap. En fallstudie som går på djupet och som ger möjlighet till en ingående beskrivning av verkligheten har valts och studien har en kvalitativ ansats. Fallet som studeras är utvecklingsverksamheten på Skatteverket som har använt det storskaliga agila ramverket SAFe som stöd i sin agila transformation. Data har samlats in genom intervjuer av personer med ledarroller och analysen av empirin är tematisk. Studiens slutsatser beskriver mötet mellan, dels den befintliga organisationsstrukturen och det storskaliga agila ramverket, dels mellan det konventionella ledarskapet och det agila. Studien ger svar på forskningsfrågan vilka lärdomar som kan ges till andra som planerar en storskalig agil transformation. Lärdomarna är kopplade till upplevelser av ett storskaliga agila ramverk, myndighetskontextens påverkan, beroenden, dubbla roller och ledarskap. / In a more complex and rapidly changing world, organizations find it difficult to keep up and take advantage of opportunities quickly enough, handle challenges and changes in customer requirements and therefore they need to increase their ability to adapt more quickly to change, something that is referred to as business agility. To better handle rapid change, organizations has adopted agile methods, but these were developed with individual teams as a model and are not intended to handle the challenges that arise when many teams work together in enterprises. For larger organizations, to achieve business agility, they need to scale up the agile methods and this change in organization is called an agile transformation. To their aid, they have large-scale agile frameworks. There are only a few case studies on agile transformation and the adaption of large-scale agile frameworks in various contexts, especially in large organizations that are strictly regulated and within the public sector. Many of the challenges and success factors that emerge from the studies and reports that do exist, are directly or indirectly linked to leadership issues, but there is limited research on the experiences of leaders, who are expected to lead the agile transformation. Some of the most reported challenges are resistance to change among employees and an organizational culture contrary to agile values. Support from leaders, communication, transparency, and increased knowledge in agile practices, are among the most reported success factors. The research objective is to examine an agile transformation, from a leadership perspective, with the support of a large-scale agile framework at government agency. The theoretical framework includes theories of importance for the understanding of business agility, agile transformation, and lean-agile leadership. A case study that goes in depth and which provides an opportunity for a detailed description of reality has been chosen and the study has a qualitative approach. The case being studied is the development department at Skatteverket (the Swedish Tax Agency), which has used the large-scale agile framework SAFe in its agile transformation. Data have been collected through interviews with people with leadership roles and the analysis of the empirical data is thematic. The conclusions of this study describe the meeting between the existing organizational structure and the large-scale agile framework, and between the traditional leadership and the agile. The study provides answers to the research question of what lessons can be given to others who are planning a large-scale agile transformation. The lessons are connected to experiences of a large-scale agile framework, the influence of the government agency context, dependencies, dual roles and leadership.

The exogenous shock that Russia's invasion of Ukraine entailed brought great challenges and demands for change in companies worldwide. Governing under these conditions is not easy, nor is knowing what is actually right to do. There is research on turbulent environments and exogenous shocks, divestments, and legitimacy, but research on the interaction between these is limited. In this study, we examine how companies have responded to exogenous shocks, more specifically how Swedish MNCs have acted and communicated as a result of Russia's invasion of Ukraine on February 24, 2022. The study consists of 69 Swedish MNCs that were active in Russia pre-invasion and their communications and actions as a result of this event, with data drawn from press releases, company reports, state registers and the media. The results show that many of the examined companies have acted in a similar way and divested the Russian market, albeit with varying quickness and forcefulness, thus adopting an approach consistent with what may be considered to be a legitimate strategy, with a few exceptions where the companies' actions has not been as consistent. What this means is that despite the fact that these decisions are made by the respective company management, the measures are generally in line with each other, which may be a result of pressure from both internal and external stakeholders and society at large.

Le secteur humanitaire a fortement évolué ces dernières années. Il est poussé à plus de transparence et doit rendre des comptes aux donateurs. Dans ce contexte, notre étude vise à expliciter, mesurer et améliorer l'une des principales caractéristiques des chaines logistiques humanitaires : leur capacité à répondre rapidement et adéquatement aux changements à court terme. Cette capacité, l'agilité, est fortement influencée par la manière dont le réseau logistique est conçu et dimensionné. Notre seconde problématique consiste donc à assurer un niveau déterminé d'agilité aux chaînes logistiques humanitaires en les aidant à mieux positionner leurs ressources. L'objectif est de montrer que l'on peut obtenir ce niveau de service enmaximisant l'efficience du réseau. Nous avons donc quantifié, en terme de coûts, l'impact de plusieurs décisions stratégiques comme le niveau de service, la proximité des fournisseurs et le degré de centralisation du réseau. / A push for increased professionalism during disaster relief operations has been reinforced over the last decade. The uncertainties humanitarian organisations have to cope with and the vital importance of their success has incited them to develop their ability to respond quickly and adequately to short-term changes. This agility capability is becoming highly prized by the private sector. Starting from a framework of supply chain agility, this thesis analyses humanitarian methods and defines an agility maturity model aiming to measure and improve the agility capability of a supply chain. As agility often depends on the adequate balance between delivery capacity and needs, our second problemstatement aims to design a logistics network that can operate under high levels of uncertainty so that for a given level of service in terms of agility, efficiency is maximized. Our study quantifies the impact on costs of various decisions, such as network design, supply strategy or level of service.

Cette thèse s’adresse aussi bien aux scientifiques, aux entraîneurs, aux préparateurs physiques et aux sportifs souhaitant approfondir leurs connaissances de l’activité football. Les aspects scientifiques abordés ainsi que leur transposition en outils de terrain pourront être utilisés comme moyen d’évaluation et d’orientation des séances d’entraînement. Ainsi, au travers de ce travail, nous avons abordé le ratio entre le temps de travail et le temps de récupération réalisés en matches de très haut niveau dans le Championnat de Première Division Italienne au cours de la saison 2004/2005. Ce ratio moyen de compétition est de 1/8, à savoir 2.2 secondes d’effort et 18 secondes de récupération. La deuxième partie de ce travail consistait à analyser l’évolution du profil d’effort et la possession de balle collective de footballeurs de très haut niveau au cours de trois saisons consécutives avec un effectif et un staff technique stables. L’étude a permis de mettre en avant une diminution de la quantité d’effort produite par les joueurs de l’ordre de 5% sans altération de la performance ainsi que l’augmentation de la possession de balle collective. La troisième et dernière partie a été de créer et d’analyser un test d’agilité spécifique à l’activité football. Après, une analyse complète des différents éléments liés à la reproductibilité et à la validité du test, il s’avère que ce test semble rendre compte de l’activité motrice du footballeur. De plus, les mesures réalisées dans le cadre de ce travail ont permis de fournir les premières normes de performance qui peuvent être attendues en fonction de l’âge du joueur et de son niveau de jeu. Au terme de notre travail, nous pouvons conclure que cette thèse a apporté des résultats spécifiques pour orienter l’entraînement athlétique du footballeur moderne et à proposer un nouvel outil de détection des jeunes footballeurs. / This work is dedicated to scientists, coaches and physical trainers as well as athletes involved in elite soccer activity. The scientific results and their practical applications could be used as a basis for the work of scientists as well as football professionals. The first part of this thesis showed that playing positions significantly influence activity profile. Moreover, this study demonstrated that the work/rest ratio observed in elite soccer Italian Serie A championship attained 1/8 and represented a mean work time of 2.2 seconds for an averaged recovery time of 18 seconds. The second part of this thesis, explored the evolution of activity profile and total ball possession during 3 consecutive seasons in the same elite team. This study has showed how for three consecutive seasons the players of successful Serie-A team reduced their distances performed at submaximal speeds, and increased ball possession while maintaining the distances covered at high/maximal speeds. It is suggested that this is due to a better understanding of tactical roles and team organization. The third part of the thesis tended to develop and to valid a specific agility soccer test composed with fundamental soccer tasks which has to be performed as quickly as possible. The validity and repeatability of the test has been demonstrated and it has been applied on a large population of different ages, positions and levels. As a conclusion, this thesis provided new specific results and perspectives that would influence professional soccer athletic conditioning and that provided a new specific test to detect young soccer players.

Title: Evaluation and training of speed in strength and conditioning preparation of youth basketball players Aims: The aim of this thesis was to validate effectivity of the training program which goal was to improve speed abilities of youth basketball players under 14 year old category during their competitive period. In the same time, I tried to evaluate how changes in selected anthropometric characteristics, practice attendance, game involvement and a length of participation in organized sport and basketball preparation influenced selected speed and agility manifestation. Methods: This thesis uses experiment as its research method. Research sample including youth basketball players (n = 9; mean age 13.39 ± 0.22 years) completed six months long training intervention with elements for speed and general strength development. Players were tested before intervention, three months and six months after beginning of the intervention. Three performance tests were used: 20 m sprint, 15 m flying with 10 m run up and lane agility drill. Video recordings of 20 m sprint and 15 m flying tests were made to evaluate changes in technique of running. Changes and interrelationships of all measured parameters were evaluated in the six months period. Results of the research sample after the first three months of...

Nos estudos sobre a teoria da Seleção Sexual, as libélulas têm sido amplamente estudadas devido à grande variedade de padrões comportamentais, de coloração e táticas reprodutivas. Como forma de demonstrar táticas reprodutivas adotadas por duas espécies de libélulas, esta dissertação teve como objetivos principais: i) investigar o papel de traços secundários como a coloração corporal na competição intra-sexual de uma espécie territorial e ii) analisar se os traços corporais como tamanho e morfologia das asas predizem a tática de acasalamento adotada por machos de uma espécie nãoterritorial. Sugere-se que a coloração corporal pode predizer o resultado de lutas e também se correlacionar positivamente com a condição física dos machos territoriais de Tigriagrion aurantinigrum. Ademais, traços corporais como o tamanho e a morfologia das asas influenciam na tática reprodutiva utilizada por machos não-territoriais de Epipleoneura williamsoni. Portanto, com os resultados obtidos, conclui-se que a variação nos sinais visuais exerce um papel essencial na comunicação animal e na resolução de conflitos, indicando ainda que pode haver uma sinalização da condição física dos machos. Além disso, os resultados mostraram evidências em como diferentes táticas reprodutivas se relacionam com traços corporais como agilidade e tamanho corporal, os quais podem influenciar no sucesso reprodutivo dos indivíduos. / In studies concerning Sexual Selection theory, dragonflies and damselflies have been well studied due to their wide range of behavioral, color and reproductive tactics patterns. To demonstrate reproductive tactics adopted by two damselfly species, this study aimed to: i) investigate the role of secondary traits such as body coloration in intrasexual competition of a territorial species and ii) analyze if body traits such as size and wing morphology predicts the adopted tactic by non-territorial males. It is suggested that body coloration can predict the fight outcome and also positively correlates with males physical condition in territorial males of Tigriagrion aurantinigrum and body traits such as body size and wing morphology influence the reproductive tactic adopted by non-territorial males of Epipleoneura williamsoni. Therefore, with these results, it is concluded that the visual signalling variation plays an important role on the animal comunication and conflict resolution, which also may indicate that there is a signalling on the males physical condition. Furthermore, the results showed evidence in how different reproductive tactics are related to body traits such as agility and size, which can influence on individuals reproductive success.

[pt] Esta dissertação apresenta uma nova ferramenta automatizada para avaliação dos processos de gestão de cadeias de suprimentos baseada no modelo de referência SCOR, apontado pela literatura como um dos mais difundidos na indústria, mas que ainda apresenta desafios significativos para a sua implantação, notadamente no que se refere à sua complexidade e custo. Endereçando estes aspectos, este trabalho especificou requisitos funcionais, um banco de dados capaz de armazenar a estrutura de dados completa do SCOR e implementou um protótipo da ferramenta denominada Supply Performer. A ferramenta, de forma inovadora, visa apoiar a implantação do SCOR sem exigir conhecimento profundo sobre o modelo ou a contratação de consultoria especializada. Para validar a sua aplicabilidade e capacidade de generalização, foi realizado um estudo aplicado em uma organização real, onde observou-se um ganho de 25 por cento na atividade de diagnóstico dos processos de Cadastro de Fornecedores e Clientes de uma empresa multinacional de grande porte. A ferramenta permitiu ainda a criação de um plano de ação e acompanhamento da evolução da melhoria dos processos, com base nas lacunas identificadas. Seu uso viabilizou a entrega rápida de resultados para o cliente, garantindo maior acessibilidade ao modelo, de forma estruturada e organizada. Em função dos resultados promissores, a ferramenta Supply Performer foi registrada no INPI (Instituto Nacional da Propriedade Industrial) BR 51 2018 000240-4. / [en] This dissertation presents a new automated tool to evaluate the processes of Supply Chain Management (SCM) based on the SCOR reference model, one of the most used models in the industry, according to the literature, but that still presents significant challenges for its adoption, notably in regards of its complexity and cost. To address these aspects, this work specified the functional requirements and a database with the whole SCORE structure, and implemented a prototype of the tool called Supply Performer, innovative because it helps SCOR deployment without the need of deep knowledge about the model, neither the hiring of a specialized consulting. To validate its applicability and generalization, the tool was used on a real case scenario and a 25 percent gain was observed in the diagnosis task of the clients and supplier registration process of a large multinational company. The tool also allowed the creation of a plan of action, and based on the identified gaps, to follow up the process improvement evolution. Its use enabled a quick delivery of results to the client, in a structured and organized way, turning SCORE into a more accessible model. On the basis of the promising results, the patent for the Supply Performer tool was registered on the INPI (Instituto Nacional da Propriedade Industrial) BR 51 2018 000240-4.
