Konkurrensen om kompetent personal ökar och flertalet faktorer används därför för attattrahera och rekrytera kvalificerad arbetskraft. Företag lägger idag stort fokus på corporatesocial recponsibility (CSR) och studier har visat att CSR spelar stor roll för potentiellamedarbetare i sökandet efter arbetsgivare. Syftet med denna uppsats är således att undersöka,beskriva och analysera huruvida studenter på avancerad nivå vid ett svenskt universitet,värderar CSR som en attraktiv faktor hos en framtida arbetsgivare. Den teoretiskareferensramen utgår från tre områden vilka berör CSR, employer branding samt social identitytheory (SIT). Uppsatsen baseras på en kvantitativ metod i form av en enkätundersökningbland 230 studenter på avancerad nivå vid ett av Sveriges största universitet. Resultaten ochslutsatserna visar, till skillnad från tidigare studier, att CSR inte ses som en attraktiv faktorhos en framtida arbetsgivare samt att andra faktorer överlag ses som både mer attraktiva ochviktiga än CSR.

Objective: Lifting-seat devices are designed to raise the seat height to reduce biomechanical and neuromuscular demands of a sit-to-stand (STS). The goal of this thesis was to understand how seat height and lifting-seat devices with different mechanisms affect trunk, hip, and knee biomechanics and neuromuscular activity of surrounding muscles, and determine whether the effects are altered by age. Four conditions were tested; 1) no device normal seat height (ND-normal), 2) Seat Assist™ (SA), 3) Power Seat™ (PS), 4) no device raised height (ND-raised). Using a cross-sectional design, two objectives were completed. Objective one compared ND-normal and ND-raised to determine the effects of seat height. Objective two compared ND-raised, PS, SA to determine the effects of lifting-seats. Design: 10 healthy older and 10 healthy younger adults performed five trials of each STS condition. Bilateral lower limb and trunk three-dimensional motion, ground reaction forces and electromyography (EMG) from five muscles were collected.

This thesis puts forward a fuzzy logic-based control strategy for artificially reproducing the sit-to-stand movement. The aim of this work is to contribute to the machine intelligence being developed for advanced mobility support devices; and specifically, those which are able to assist the mobility impaired user with the sit-to-stand task. Three fuzzy logic controllers were designed. The first controller seeks to move the model into the “most stable” configuration. The second seeks to move the model toward the goal configuration (i.e., standing). And the third combines the output from the first two controllers to produce a unified control action. Each controller was implemented and tested in software using Mathwork’s Matlab(TM). The results of the software simulation were compared against motion capture data taken from a single healthy male test subject. The automated controller was shown to produce a movement very similar to the natural sit-to-stand movement.

Standing up from a seated position, known as sit-to-stand (STS) movement, is one of the most frequently performed activities of daily living (ADLs). However, the aging generation are often encountered with STS issues owning to their declined motor functions and sensory capacity for postural control. The motivated is rooted from the contemporary market available STS assistive devices that are lack of genuine interaction with elderly users. Prior to the software implementation, the robot chair platform with integrated sensing footmat is developed with STS biomechanical concerns for the elderly. The work has its main emphasis on recognising the personalised behavioural patterns from the elderly users’ STS movements, namely the STS intentions and personalised STS feature prediction. The former is known as intention recognition while the latter is defined as assistance prediction, both achieved by innovative machine learning techniques. The proposed intention recognition performs well in multiple subjects scenarios with different postures involved thanks to its competence of handling these uncertainties. To the provision of providing the assistance needed by the elderly user, a time series prediction model is presented, aiming to configure the personalised ground reaction force (GRF) curve over time which suggests successful movement. This enables the computation of deficits between the predicted oncoming GRF curve and the personalised one. A multiple steps ahead prediction into the future is also implemented so that the completion time of actuation in reality is taken into account.

Falls are one of the most serious problems among the elderly, resulting in fatal physical injuries. Early identification of people at a high risk of falling is needed to facilitate rehabilitation to reduce future fall risk. The overall goal of this dissertation was to develop biomechanical models that identify dynamic limits of balance control in daily functional activities associated with falling, including sit-to-stand (STS) movement, standing (stance perturbation), and walking. Poor performance of STS movement has been identified as one of the risk factors of falls among elderly individuals. We proposed a novel method to identify dynamic limits of balance control during STS movement using whole body center of mass (COM) acceleration and assessed its feasibility to differentiate individuals with difficulty in STS movement from healthy individuals. The results demonstrated that our model with COM acceleration could better differentiate individuals with difficulty in STS movement from healthy individuals than the traditional model with COM velocity. Poor postural control ability is also a risk factor of falls. Postural recovery responses to backward support surface translations during quiet standing were examined for healthy young and elderly adults. The results demonstrated that functional base of support (FBOS) and ankle dorsiflexor strength could be sensitive measures to detect elderly individuals with declined balance control. Our biomechanical model, which determines a set of balance stability boundaries, showed a better predictive capability than the statistical model for identifying unstable balance recovery trials, while the statistical model better predicted stable recovery trials. Lastly, walking requires a fine momentum control where COM acceleration could play an important role. Differences in control of dynamic stability during walking were examined with our proposed boundaries of dynamic stability. Elderly fallers adapted a more conservative gait strategy than healthy individuals, demonstrating significantly slower forward COM velocity and acceleration with their COM significantly closer to the base of support at toe-off, which could be indicative of a poor momentum control ability. Overall, this study demonstrated that COM acceleration would provide further information on momentum control, which could better reveal underlying mechanisms causing imbalance and provide an insightful evaluation of balance dysfunction. This dissertation includes unpublished co-authored material.

Para isso, foram realizados 2 estudos independentes: o estudo 1 teve como objetivo avaliar o efeito agudo da TFBM aplicada imediatamente após sessão de SIT sobre as respostas inflamatórias (IL-10 e TNFα), marcadores de lesão muscular (CK e LDH), percepção de dor muscular e no desempenho em salto vertical. O estudo 2 teve como objetivo comparar a efetividade da TFBM nas mesmas variáveis do estudo 1, mas comparando esse método com outros métodos de recuperação já clássicos na literatura, como a como a re-cuperação ativa (RA), imersão em água fria (IAF). Participaram do projeto 36 voluntários não treinados (12 participantes no estudo 1 e todos os 36 no estudo 2). No estudo 1 o desenho experimental foi designado como duplo-cego, randomizado e controlado por placebo e no estudo 2 foram utilizados grupos independentes para cada intervenção. Os voluntários foram submetidos a um teste incremental máximo, seguido (5 dia depois) de duas sessões de SIT (4 x teste de Wingate, com recuperação de 4 min entre os esforços) em um intervalo de 24 h. Imediatamente após a segunda sessão de SIT foram aplicadas a TFBM (músculos quadríceps e bíceps femoral em ambas as pernas), ou Placebo (PLA) (estudo 1) e TFBM, RA (15 min a 50% da menor intensidade associada ao consumo máximo de oxigênio) ou IAF (10 min à 10 °C) (estudo 2). Amostras de sangue venoso foram coletadas antes (Pré), 30 min, 1, 24, 48 e 72 h após a segunda sessão de SIT, além disso, nos momentos 24, 48 e 72 h foram realizadas avali-ações da percepção de dor e salto vertical contra movimento. Não foram verificadas interações entre os grupos no estudo 1 e no estudo 2 para nenhuma das variáveis investigadas. No entan-to, por meio da análise da magnitude do tamanho do efeito foram verificados efeitos benéfi-cos sobre alguns parâmetros analisados e diferenças entre as intervenções. Com base nos resul-tados dos estudos 1 e 2, de modo geral, a TFBM teve um efeito ligeiramente benéfico sobre a recuperação muscular após sessões de SIT em ciclo ergômetro. No entanto, os efeitos da TFBM não foram predominantemente melhores sobre os parâmetros de recuperação muscular quando comparados com os efeitos da RA e a IAF. / The general objective of the present project was to investigate the effectiveness of photobiomodulation therapy (FBMT) on muscle recovery after sprint interval training (SIT) sessions on cycle ergometer. Two independent studies were performed: study 1 aimed to evaluate the acute effect of FBMT applied immediately after SIT session on inflammatory responses (IL-10 and TNFα), markers of muscle injury (CK and LDH), CMJ performance and pain perception. Study 2 aims to compare the effectiveness of FBMT using the same variables of study 1, but comparing this method with other classical recovery methods in the literature, such as active recovery (AR) and cold water immersion (CWI). Thirty-six untrained volunteers participated in the studies (12 participants in study 1 and all 36 in study 2). In study 1 the experimental design was designated as double-blind, randomized and placebo-controlled and in the study two independent groups were used for each intervention. The subjects performed a maximal incremental test, followed (5 days later) by two sessions of SIT (4 x Wingate test, with recovery of 4min between the efforts) in a period of 24 hours. Immediately following the second SIT session, the FBMT (quadriceps and femoral biceps muscles in both legs) or Placebo (study 1) and FBMT, AR (15 min at 50% of the lowest intensity associated with peak oxygen uptake) or CWI (10 min at 10 ° C) (study 2). Venous blood samples were collected before, 30 min, 1, 24, 48 and 72 h after the second SIT session; in addition, at 24, 48 and 72 h was performed evaluations of CMJ performance and pain perception. There were no interactions between groups in study and study 2 for any variables. However, using the qualitative analysis of the magnitude of differences was found beneficial effects on some parameters analyzed and differences between interventions. In summary, based on these results, FBMT had a slightly beneficial effect on muscle recovery after SIT sessions in cycle ergometer. However, the effects of TFBM on muscle recovery parameters were not predominantly better when compared to AR and CWI effects. / FAPESP: 2015/05012-2

Sjuksköterskornas revolution är en kvalitativ studie om organisatorisk identifikation. Syftet med studien är att skapa djupare förståelse för hur sjuksköterskornas organisatoriska identitet påverkas av att arbeta genom entreprenadbemanning inom vården. Studiens frågeställningar handlar om hur sjuksköterskorna upplever att arbeta inom en entreprenadbemanning inom landstinget, hur de upplever sin organisatoriska identifikation och hur organisationernas arbetssätt kan påverka identifikationen. Ämnet är valt då entreprenadbemanning är ett relativt nytt fenomen inom vården vilket gör att det saknas kunskap kring ämnet. Studien utgår från en fältstudie där samtlig empiri är insamlad via semistrukturerade intervjuer med bemanningssjuksköterskor samt nyckelpersoner från både sjukhuset och bemanningsföretaget. Studiens analysverktyg består av social identitetsteori och social identitetsteori inom organisationer. Begrepp som används för analysen är bland andra; självidentitet, social kategorisering, social identifikation, social jämförelse och undergrupper. Studiens teoretiska bidrag pekar på att sjuksköterskorna till viss del identifierar sig med båda organisationerna och det tar sig uttryck i att sjuksköterskorna identifierar sig med sjukhuset då det är deras fysiska arbetsplats och med bemanningsföretaget för att det är deras arbetsgivare. Däremot sker den primära identifikationen snarare till den egna in-gruppen, vilket bara består av sjuksköterskor från bemanningsföretaget. Den starka gemenskap sjuksköterskorna beskriver består av välvilja och en stark teamkänsla.
