Title: Appropriateness of choice to walk or run, depending on the speed of a quick relocation with load carriage Objectives: Comparison of physiological response of organism during the walk and run at speed 6 - 7,4 km.h-1 with carried load 15 kg with follow-up determination of critical speed in connection with economy of these activities where there were discovered sizes of correlation with proportional representation of fat free mass and working length of lower limb. Methods: The method applied in this research was the quantitative research based on intra-individual and inter-individual comparative analysis. Results: Based on the measured data it has been found out that there is a critical speed at 7,43 km.h-1 (±0,53), with respect to economy of walk compared to run with 15 kg load. The average heart rate during the critical speed was 129 BPM (±9,67). The average energy expenditure per minute during the critical speed was 11,9 kcal (±2,04). In addition there were discovered sizes of correlation between critical speed and the working length of lower limb where rP = 0,9203 was statiscitally significant. (α = 0,05) and between critical speed and proportional representation of fat free mass, where rP = 0,1529 was not found to be statistically significant (α = 0,05).

The purpose of this dissertation is to analyze Swedish male handball players power in the lower limbs, dependent on position, in different anatomical planes. Previous studies has examined vertical and horizontal power but not medial lateral power. This study used previous studies as theory. Power was examined through vertical, horizontal and medial lateral CMJAS, unilateral and bilateral, in a laboratory setting. The vertical jumping performance was measured with ‘My Jump 2’ and the vertical power (W; W/kg) was calculated with Lewis formula. Only the jumping performance (cm) was noted in the horizontal and medial lateral CMJAS. No significance difference was observed (p>0.05) in power between the positions. A strong correlation between the vertical and horizontal CMJAS was observed (p<0.05; r=0.860-0.883). Conclusion, handball players, independent position, possesses similar power, bilateral and unilateral, in vertical, horizontal and medial lateral CMJAS. Medial lateral power needs to be examine to create a better profile of the player.

These days, everything revolves around technology, and we have instantaneous access to all information. To stay up to date on current events, we get notifications on our smart devices when relevant articles or messages become available. Displays and other forms of technology are ubiquitous in today's car interiors to both enhance the driving experience and keep the driver in touch with the information they provide. However, depending on the situation and task at hand, these notifications can elicit a variety of reactions from us when they appear at an inconvenient time. The problem statement of this research was that there was very little amount of research done on the connection between drivers with different personality traits and how the incoming in-vehicle notifications affect them in various cognitive load scenarios. This study put participants in a practical research where they have been doing a primary task while interacting with notifications as a side task. The tasks at hand have been divided based on the user's cognitive load, or the amount of focus required for that activity, like different driving scenarios in real life. We have collected sufficient data through practical research in which participants have been placed in a scenario of performing a primary task while interacting with incoming notifications. Prior to that, the personality traits of the participants have been determined using a survey, which assisted us in connecting the similarities and differences among the various personality trait groups. In the practical part of the study, a screen was used on which the participant performed a primary task in the form of a video game, as well as a screen beside him, mimicking an infotainment screen, with incoming notifications with which he had to interact. This provided us with accurate data based on its similarity to an actual everyday scenario, such as while driving a car. The findings aided in establishing a clear link between personality traits, levels of cognitive load, and notifications in general, and how they are interlinked.

Background Timing and quantity of protein (PRO) consumption are important considerations for muscle protein synthesis (MPS), fat-free mass (FFM) accretion, and body fat % (BF%) reduction. The effect of PRO ingestion on changes in FFM is mediated by many variables. Past studies have focused on specific composition of carbohydrate (CHO) and PRO consumption (CHO vs. PRO + CHO), and have also investigated PRO intake timing at pre-exercise, post-exercise, or both. Other studies have investigated FFM maintenance and growth with increased PRO consumption during catabolic or anabolic phases of energy balance (EB). These mechanisms have been studied in various populations, including healthy untrained individuals, overweight and obese people, and endurance athletes. However, studies have not explored relationships between the amount and timing of PRO ingested, and the state of EB, as it relates to FFM%. Method/Design A retrospective analysis design was used to assess relationships between PRO ingestion, timing, and EB on FFM in collegiate football players. Subjects were members of an intercollegiate Division 1 football team, had completed a one-day food and activity record, and had body composition assessed as part of a regular team screening procedure. Data acquisition was supervised by a PhD/Registered Dietitian. Food and activity records were analyzed using NutriTiming®, which predicts RMR via the Harris-Benedict equation, uses a MET-based relative intensity activity scale, and accesses the USDA Nutrient Database for Standard Reference, Release 26 to predict hourly EB and PRO consumption. EB was assessed as ±400 kcal EB (EBR), < 0 kcal EB (NEGEB), and > 0 kcal EB (POSEB). Total useable PRO (TUP) was defined as the sum of PRO consumed in units up to 30g max/meal, a value also assessed relative to EB at the time of ingestion. The goal was to assess the amount and timing of PRO intake with EB as these factors relate to FFM. Results Pearson's correlations found that BF% was negatively associated with TUP while in EBR (r=-.253; p=0.049), and FFM% was positively associated TUP in EBR (r=0.279; p=0.030) and in POSEB (r=0.282; p=0.028). NEGEB was positively associated with BF% (r=0.325; p=0.011), and negatively associated with FFM% (r=-0.322; p=0.011). Conclusions Results elucidate that players who ingest PRO in a relatively good energy-balanced state had higher FFM% and a lower BF%. Further, those players consuming TUP while in POSEB had an even stronger positive association with FFM% and a stronger inverse association with BF%. These data reject the null hypothesis that football players who consume PRO in POSEB have less FFM% than those who consume PRO in NEGEB.

Orientation In this study the interrelationship between specific personality and interests measures were explored to improve understanding of the respective constructs and their interrelations. A literature study and empirical research was conducted to serve the purpose of this study. Research purpose The purpose of this study was to explore the interrelationship between personality and interests using the measures of the OPQ, the 15FQ+, and the SDS. Motivation for study Much research has been done on the importance of the use of personality and interest questionnaires for career guidance and other purposes. However, a correlation between the SDS and OPQ and between the SDS and 15FQ+ has not been researched. As such, this study was intended to provide valuable insight into the interrelation between the personality and interests as measured by the OPQ, the SDS and the 15FQ+, which should enhance the interpretation of the respective constructs. Research Methodology An exploratory research method was used, as it was a systematic investigation of the relationship among two or more variables. A quantitative strategy of inquiry was used for this study. Main findings A canonical correlation analysis showed moderate to strong interrelationship between personality traits and vocational interest. The interrelation of the OPQ, the SDS and the 15FQ+ are significant. The findings indicated how personality and interests differ and converge for enhancing interpretation purposes. Practical/managerial implications Holland’s theory of vocational interests focuses on the application of the SDS for career purposes, as well as for measuring job fit and job satisfaction. A better understanding of the interrelationship between personality and interests help practitioners to optimize the use of the measures within various contexts. Contributions/value additions The study will enable practitioners to more effectively utilize the personality and interest measures, combined or separately, as the interrelationships are now better known and construct validity is enhanced. Conclusion The objective of this research was successfully achieved, as satisfactory evidence was provided to address the overarching research purpose. / Dissertation (MSc)--University of Pretoria, 2014. / Human Resource Management / MSc / Restricted

人之性格與行為到底是由與生俱來的先天因素（nature）抑或環境行為等後天因素（nurture）決定呢？這方面的爭議是心理學家數十年來的興趣。然而，近十年中工業與組織心理學家才開始注意到，工作滿意與工作價值觀之氣質（disposition）源起與影響程度。本研究之目的，即在探討「五大人格特質」、「工作價值觀」、「工作滿意」三者間的關係。 本研究所使用的樣本乃為台灣之某一國營企業員工，有效樣本共568位。研究結果發現：五大人格特質與工作滿意是有所關係的，其中嚴謹自律性、外傾支配性、和善性分別對工作滿意具有預測力。五大人格特質對於內在滿意的影響則高於外在滿意；此外，研究者亦提出實徵數據佐證五大人格特質是可以有效地預測工作價值觀，解釋量約為45%；而且工作價值觀也會影響工作滿意且關係密切，與西方或是東方之台灣與韓國的研究相當一致。最重要的是本研究也發現工作價值觀(之工作目的性價值觀與工作手段價值觀均)為五大人格中之嚴謹自律性與內在滿意以及外向性與一般滿意之中介變項。此外，工作手段價值觀僅為五大人格中之和善性與一般滿意之中介變項。 綜合本研究結果與發現，研究者指出本研究之限制與未來研究方向，嘗試整合工作滿意之人格氣質緣起的架構並建立模式。以供工業與組織心理學家以及組織行為學者作為參考。 關鍵字：五大人格特質、工作價值觀、工作滿意、中介變項、氣質 / For decades, the debate over the issue of whether personalities and behaviors of human beings are determined by Nature or Nurture has been one of the major research interests of psychologists. However, it was not until the past ten years that industrial/organizational psychologists started to notice the dispositional sources of and their effects on job satisfaction and work values. In line with this trend, the present study aimed to investigate the relationships between the Five Factor Model of Personality (FFM, also known as the Big Five), work values, and job satisfaction. The study sampled 568 employees from one of the state-operated enterprises in Taiwan, and the Big Five was found to be related to job satisfaction, which could be predicted by Conscientiousness, Extraversion, and Agreeableness, respectively. The influence of the Big Five over intrinsic satisfaction was higher than that over extrinsic satisfaction. In addition, the researcher provided empirical data to substantiate the notion that the Big Five could predict work values effectively, accounting for 45% of the variance. The finding of a strong association between work values and job satisfaction was consistent not only with other research results obtained from eastern countries such as Taiwan and Korea, but also with those obtained in the West. Most important of all, terminal and instrumental work values were found to be the mediator between Conscientiousness and intrinsic satisfaction, as well as that between Extraversion and general satisfaction. However, only terminal work values served as the mediator between Agreeableness and general satisfaction. Summing up the results and discoveries of the present study, the limitations of it were pointed out, and directions for further investigation were suggested. Trying to construct a model by integrating the dispositional sources of job satisfaction and work values into a framework, the researcher wished to provide a footstone of future research for other industrial/organizational psychologists as well as organizational behaviorists.

Depuis son invention en 1986, les microscopes à force atomique (AFM) ont été des puissants outils pour la caractérisation des matériaux et des propriétés des matériaux à l'échelle nanométrique. Cette thèse est entièrement dédiée à la mesure de l'interaction entre une sonde AFM et une surface avec une nouvelle technique AFM appelée Force Feedback Microscopy (FFM). La technique a été développée et utilisée pour l'étude d'échantillons biologiques. Le principe central de la technologie FFM est que la force totale moyenne appliquée à la pointe est égal à zéro. En conséquence, en présence d'une interaction pointe-échantillon, une force égale et contraire doit être appliquée à la pointe par une boucle de rétroaction. La force de réaction est ici appliquée à la pointe à travers le déplacement d'un petit élément piézoélectrique positionné à la base du levier AFM. La boucle de rétroaction permet d'éviter instabilités mécaniques tels que le saut au contact, permettant la mesure complète de la courbe d'interaction. En plus, il donne la possibilité de mesurer simultanément les parties élastique et inélastique de l'interaction. La technique a été appliquée à l'étude des interactions à l'interface solide/gaz, avec un intérêt particulier pour l'observation de la formation et de la rupture des ponts capillaires entre pointe et échantillon. Ensuite, on a focalisé notre attention aux interfaces solide/liquide. Dans ce contexte, courbes complètes de type DLVO sont caractérisées d'un point de vue élastique et dissipatif. Nous avons développé des nouveaux modes d'imagerie AFM pour l'étude des biomolécules. Images de phospholipides et de l'ADN à force constante ont été réalisées et certaines propriétés mécaniques comme le module de Young des échantillons ont été évaluées. En plus, nous avons réalisé une étude spectroscopique de l'élasticité et du coeffcient d'amortissement de l'interaction entre des cellules vivantes de type PC12 et une pointe AFM en nitrure de silicium. L'étude montre que le FFM est un instrument capable de mesurer l'interaction à des fréquences qui ne sont pas nécessairement liées aux résonances caractéristiques du levier. L'étude spectroscopique pourrait avoir dans le futur des applications importantes pour l'étude des biomolécules et des polymères.
