This thesis aims to explore the two dominant functional roles of the hippocampal formation, in the relational encoding of episodic memory and the neural representation of allocentric space, using a combination of pharmaceutical manipulations and single-unit recording techniques in rodents. The first part of this thesis focuses on episodic-like memory, defined by the original episodic memory triad: ‘what-where-when’ (Tulving 1972), which enables the behavioural aspects of episodic memory to be tested in non-human animals. Permanent neurotoxic lesions of the hippocampus and it’s subregions were induced to assess their role in a putative episodic-like memory task developed by Eacott and Norman (2004). In view of the difficulties encountered in successfully demonstrating the temporal component of episodic-like memory in rats, this task tested integrated memory for ‘what-where-which’, where the temporal component (when) was replaced with another event specifier: context (on ‘which’ occasion). Disruption of the hippocampal circuitry led to a specific impairment in the integration of all three event components, whereas the associative recognition of any combination of these features in isolation was left intact. These results confirm the hippocampal dependence of this episodic-like memory task and further reveals the necessity of both CA3 and CA1, hypothetically due to the underlying autoassociative role of CA3 with CA1 functioning as the vital output pathway for this associated information and/or as a mismatch detector. There has been much debate over the inclusion of the temporal component and sceptics may argue that any such interpretations of task-dependence on episodic-like memory processing are invalid considering the requirement for temporal processing is absent. Due to the proposal that a temporal framework necessarily provides the foundation on which episodic memories are built, the second chapter focuses on the development of a suitable protocol in which integrated memory for the original ‘what-where-when’ episodic memory triad can be reliably tested. The other main function attributed to the hippocampus was brought to light by the fascinating revelation that it’s neurons selectively fire in different regions of an environment, termed ‘place cells’ (O’Keefe and Dostrovsky 1971). From the numerous publications resulting from this discovery it has emerged that place cells not only respond to the spatial features of the environment but are also sensitive to a multitude of non-spatial features. These characteristics support the logical assumption that the primary firing patterns of the hippocampus should underlie it’s main purported roles, leading to speculations that they reflect episodic memory processes. The second part of this thesis aims to examine the relationship between hippocampal cells and behaviour by extending the work of Ainge et al. (2007a), in which a subset of hippocampal place cells were found to encode both current and intended destination in a double Y-maze ‘win-stay’ task. The development of these ‘goal-sensitive’ cells were initially investigated during the learning phase of this task. An exciting pattern of results showed a strong positive correlation between the emergence of goal-sensitive firing and behavioural performance on the task, tempting speculations that these firing patterns may underlie spatial learning and future planning, necessary to support performance. To ensure these firing patterns were not a mere reflection of greater experience on the maze, a second study was conducted in which the task demands changed over set periods of days. A significant increase in the proportion of cells demonstrating goal-sensitive firing was revealed when the protocol shifted to incorporate the spatial memory demands of the ‘win-stay’ task, with all other parameters of the protocol remaining constant. These results support the theory that goal-sensitive firing patterns are specifically related to the learning and memory demands of the spatial task, not a result of increased exploration of the maze. The last of this series of studies assessed hippocampal-dependence of this task and revealed that bilateral hippocampal lesions induced an impairment in spatial ‘win-stay’ performance. Collectively, these experiments demonstrate that goal-sensitive firing of hippocampal cells emerge in line with behavioural performance in a hippocampal-dependent task and the emergence of these firing patterns are specific to the learning and memory demands of a spatial ‘win-stay’ protocol. The functional role of the hippocampus in allocentric spatial processing may thus underpin it’s function in episodic memory and potentially in the imagining and planning of future events, whereby the hippocampus provides a ‘space’ in which retrieved information can be integrated in a coherent context to support the fluent and flexible use of information. This hippocampal function would necessarily require visual information to be accessed, concerning the arrangement of landmarks and cues within the environment, in association with information regarding internal orientation and direction and this leads to the question assessed in the final part of this thesis of where this integration occurs. Based on anatomical evidence and the current literature, the postsubiculum, an input structure to the hippocampus, emerged as a potential site for the convergence of sensory cues into the internally generated head direction cell and place cell networks to enable hippocampal-dependent spatial processing. Thus, the effects of temporary pharmacological blockade of AMPARs and NMDARs in the postsubiculum were assessed on the encoding of spatial memory in an object recognition paradigm. The impairment revealed in the ability to recognise novel object-place configurations demonstrates a key role for NMDAR-dependent plasticity within the postsubiculum itself in the formation of allocentric spatial memory. In summary, the experimental results reported in this thesis further elucidate the critical role the hippocampal formation plays in spatial and episodic memory by combining evidence from cellular physiology and neuroanatomy to the behaving animal and extends these findings to discuss a more general role for the hippocampus in imagining both past and future events, in order to successfully navigate, learn and enable past experience to influence our intended future plans and decisions.

This study analyses the way information regarding performance measurements is shared among employees working at the shop floor at Dalvich Optic in Sweden. This study is conducted because many companies failed to implement a system that facilitates daily performance measurements as they neglected the assembly operators’ role in decision making process. Companies focus on measuring wrong parameters and visualize information about performance measurements in wrong way. The purpose of this study is to demonstrate that new Information Technology (IT) artefacts are designed by experts for use by experts. IT artefacts are designed without taking into account assembly operators’ skills, education and experiences. Thus, limiting assembly operators’ ability to achieve daily production goals. Therefore, this study highlights the role of both assembly operators and visualizing information at the shop floor and their impact on performance measurements and productivity.   After analysis, this study develops a new IT artefact. The implementation of the new IT artefact at the company leads to a new leadership where management meet assembly operators in a daily basis, creating good environment for direct communication. As a result, the company increased its production by 50 percent compared to the previous year and it has doubled the production compared to 2010. The information about production status became visible and accessible to all employees since the information displayed through the new IT artefact was monitored in an easy-to- understand way. The presentation and visualization of information regarding productivity offered assembly operators and managers the possibility to react quickly when any disparity concerning goal achievement arose. As a result, the new IT artefact enhances assembly operators’ participation at the manufacturing process as well. Assembly operators took active role on manufacturing process since information about performance measurement was compiled and maintained by themselves; thus, positively influencing production outcomes. Furthermore, a new IT artefact created an arena where employees contributed to continuous improvements and problem-solving at work.   This study was conducted during a period of six months. Data was gathered through observations, interviews, and meetings with managers and assembly operators at a manufacturing plant. Furthermore, data from books, articles, and journals helped in analysing the way information was visualized and communicated in a manufacturing plant. ADR, Action Design Research method was used to design a new and simple IT artefact that considers employees’ skills, experiences and education.

This dissertation consists of two largely stand-alone chapters. The first chapter presents a goal-activation theory of the antecedents of advice taking. I propose that three separate categories of goals - decision quality, social standing, and emotional well-being - influence receptivity to advice. Decision quality goals increase striving toward a good outcome in the decision for which the advice was given. Social standing goals focus attention on the social effects of the act of taking or rejecting the advice. Emotional well-being goals are related to establishing or maintaining a desired affective state. Each of these goals can be activated by attributes of the situation, advice, advisee, and advisor. Because they increase striving toward different ends, the goals direct attention to disparate advice-related cues and affect the evaluation of those cues. This results in different responses to advice. At the current time, nearly all research on advice taking has addressed decision quality goals and related cues. By presenting this theory, I hope to increase interest in a wider set of antecedents of advice taking. The second chapter reports a series of studies testing hypotheses derived from the theory presented in the first chapter. Specifically, I contrast the effects of an advisor's relative expertise to effects of the advisor's relative hierarchical position on advice taking. I hypothesize that the effects of expertise are driven by decision quality goals, while the effects of relative hierarchical position relate to social standing goals. I further hypothesize that advisees' conceptions of appropriate leader-follower relations (specifically, follower co-production role orientation; Carsten & Uhl-Bien, 2012) activate social standing goals, but not decision quality goals. Lastly, I propose that outcome accountability increases attention to decision quality goals and reduces attention to social standing goals.

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / A ground based intelligent agent and operations network is being created to handle all aspects of spacecraft command and control. This system will have the dual purpose of enabling cost efficient operation of a number of small satellites and serving as a flexible testbed for the validation of space system autonomy strategies. The system is currently being targeted to include over a dozen globally distributed amateur radio ground stations and access to nearly ten spacecraft. The use of distributed computing systems and virtual interaction schemes are significantly contributing to the creation of this system. The Internet is used to link the network's control centers and ground stations. In addition, a World Wide Web (WWW) based user and operator interface is being developed to permit high level goal specification of spacecraft experiments and actions. This paper will describe the operating network being developed, the use of the Internet as an integral part of the system's architecture, the design of the WWW interface, and the future development of the system.

Community colleges serve a diverse population of learners including many older students counting on the community college for enhanced skills or personal enrichment. Many of these colleges target this population with programs designed specifically to meet the needs and goals of the older adult but may not consider this population when designing a website. Older users of a community college website have similar needs to the traditional student; however, little was known about the impact of the typical navigational links on the successful completion of tasks and obtaining information for this type of user. It is essential for educational institution website designers to understand which navigational links will provide the best usability for older adults with differing levels of experience. Previous research has found that usage-oriented links and pages that offer both usage and subject-oriented links yield statistically higher performance than subject-oriented links. Other research has found that presenting navigational links in the form of an action enhances usability. For this study, three websites were created utilizing navigational links in the form of usage-oriented links, subject-oriented navigational links, and then a combination of both to conduct a usability study to expand on previous work. This study was designed to determine the impact of such navigation on obtaining the correct answer, time on task, and the user's perception of the navigation. The research question, Does website usability and the user's perception of usability vary for older users based on navigational links, task type, and audience type? was addressed through two hypotheses and data which were obtained during the study. The first hypothesis: Website navigation, task type, and audience type significantly affect usability, was based on performance, and was measured on the two components, correct answer ratio (CAR) and navigation time (NT). The results indicated that the older user's ability to complete tasks faster and more accurately depended on the user's experience level, the difficulty of the task, and the types of navigational links presented, with usage-based navigation being the more effective solution. The second hypothesis: Website navigation, task type, and audience type significantly affect perceptions of usability, was based on perception questions presented after task completion and was measured by a four question post-test questionnaire, which used a 7-point Likert scale. This study found the older user's perception of usability varied based on the navigational links presented, but the experience level of the participant or the task type did not have a significant effect on the perception of usability. Therefore, it is recommended that designers of educational sites present navigational links in a goal-oriented, action-based format to support the end users of all ages and to enhance usability of the institution's website. This research found that if developers emphasize accuracy and the need to navigate quickly as a goal of an educational website for the older user, the website should be designed using a usage-based navigation structure. This research provides the detail to support a better understanding of which navigation type results in higher usability for the older user and enhances the guidelines of website design for this population.

Föreliggande studie syftade till att undersöka sambandet/effekten mellan målsättning, behovstillfredsställelse, behovsfrustration, motivation och träningsfrekvens bland gymaktiva vuxna. Utifrån två arbetsmodeller utformades två hypoteser som testades via medieringsanalyser. En kvantitativ forskningsansats genomfördes där respondenterna fick besvara ett enkätformulär med frågor från mätinstrumenten: Godin Leisure- Time Exercise Questionnaire, Task and Ego Goal Orientation in Sport Questionnaire, The Balanced Measure of Psychological Needs, samt Behavorial Regulations in Exercise Questionnaire. Utifrån ett bekvämlighetsurval rekryterades 128 respondenter (70 kvinnor och 58 män) i åldern 19-36 (M = 22.3, SD = 2.5) som deltog i studien. Medelvärdet på antal träningspass/vecka (lätt, måttlig och hård träning) uppkom till cirka nio stycken bland deltagare. Studiens huvudsakliga fynd var att prestationsmål korrelerade positivt med identifierad reglering, inre motivation, tillfredställelse av de tre grundbehoven samt självbestämmande motivation. Det fanns även ett positivt samband mellan inre motivation och träningsfrekvens. Vidare visade resultatet ett positivt samband mellan resultatmål, amotivation och behovsfrustration. De två hypoteserna förkastades då resultatet inte genererade några direkta medierande effekter. För framtida forskning föreslås bland annat studier som syftar till att undersöka hur effekten på träningsfrekvens kan påverkas beroende på målorientering, samt föreslås ytterligare studier som undersöker behovsfrustration i samband med gymkontexter. / The present study aimed to investigate the relationship/effect between goal orientation, needs satisfaction, needs frustration, motivation and training frequency among gym active adults. Based on two working models two hypotheses were designed and tested through mediation analyzes. A quantitative research approach was conducted in which respondents were asked to answer a questionnaire with questions from the following measuring instruments: Godin Leisure- Time Exercise Questionnaire, Task and Ego Goal Orientation in Sport Questionnaire, The Balanced Measure of Psychological Needs and Behavioral Regulations in Exercise Questionnaire". From a convenience sample, 128 respondents (70 women and 58 men) in the age 19-36 (M = 22.3, SD = 2.5) were recruited who participated in the study. The average number of training sessions/week was about nine for the participants. The study's main finding suggest that task goals positively correlated with identified regulation, intrinsic motivation, satisfaction of the three basic needs and self-determination motivation. There was also a positive correlation between exercise frequency and intrinsic motivation and exercise frequency. The results also showed a positive correlation between ego goals, amotivation and thwarting. The two hypotheses were rejected because the result did not generate any direct media effects. For future research, it is suggested to design studies that aim to investigate how the effect of exercise frequency may be affected depending on the goal orientation, and further suggested studies that investigate thwarting in relation to gym contexts.

Thesis (MScPhysio (Interdisciplinary Health Sciences. Physiotherapy))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Background: Children who lack the motor coordination to perform the tasks that have usually been acquired at their age, given normal intellectual ability and the absence of other neurological disorders, are classified as having Developmental Coordination Disorder (DCD) according to DSMIV. Limited professional resources prohibit individual therapy and these children are being treated in “gross motor groups” regardless of the fact that this has limited proven efficacy. This study aims to investigate whether group exercise physiotherapy does improve the gross motor function of children with DCD aged six to ten years old. Methods: Thirty-nine children were assessed at pre and post intervention on the Movement Assessment Battery for Children (M-ABC) as well as the Perceived Efficacy and Goal Setting (PEGS) questionnaire by a blinded research assistant. They were randomly allocated to either a control (N=19) or an intervention group (N=20). The intervention group was then further subdivided into groups of four to six per group to attend group exercise sessions of 30 – 45 minutes three times per week. Group exercises were aimed at improving manual dexterity, ball skills and balance by incorporating aerobic exercises, strengthening exercises, coordination as well as task specific activities. Results: There was a significant increase (p=.028) in the total scores tested by the experimental group on the M-ABC after the eight week intervention. Manual dexterity skills had improved significantly (p=.035). There was a trend for ball skills to improve (p=.088) but no improvement was recorded for static or dynamic balance post intervention. PEGS results indicated that subjects considered themselves as very competent regardless of their abilities. Conclusions: The results of this study support the hypothesis that an eight week group exercise program can improve the gross motor skills of children with DCD. It would seem that implementing such an intervention is a viable option, especially where resources limit the availability of one to one therapy. / AFRIKAANSE OPSOMMING: Agtergrond: Kinders wat „n gebrek aan motoriese koördinasie het om ouderdoms verwante take te verrig, gegewe dat hulle normale intellektuele vermoëns het en die afwesigheid van ander neorologiese abnormaliteite, word geklassifiseer as “Developmental Coordination Disorder” (DCD) volgens die DSM IV. Beperkte professionele menslike hulpbronne voorkom individele terapie en hierdie kinders word gewoonlik behandel in grofmotoriese groepe, ongeag dat daar min bewyse is dat dit „n effektiewe behandelings metode is. Die doel van hierdie studie is om vas te stel of „n fisioterapie groepsoefenprogram „n effektiewe behandelingsvorm is om die grofmotoriese vaardighede in ses tot tienjarige primêre skool kinders, met „n diagnose van DCD, verbeter. Metodes: Nege-en-dertig kinders was geassesseer met die “Movement Assessment Battery for Children” (M-ABC) en die “Perceived Efficacy and Goal Setting” (PEGS) vraelys deur „n geblinde navorsingsassistent. Hulle is in twee groepe nl kontrole groep wat nie intervensie gekry het nie (N=19) en „n eksperimentele groep (N=20)verdeel deur eenvoudige ewekansige toewysing. Die eksperimentele groep was verder onderverdeel in groepe van vier tot ses om groepsoefeningsessies by te woon drie keer „n week vir 30 tot 45 minute. Die doel van die groepsoefeninge was om die volgende areas te verbeter: handvaardigheid, balvaardigheid en balans deur die inkorporasie van balansaktiwiteite, spierversterkingsoefeninge, koördinasie sowel as taak spesifieke aktiwiteite. Die deelnemers was weer geassesseer met die Movement-ABC en die PEGS na die agt weke lange intervensie program. Resultate: Daar was 'n beduidende toename (p=.028) in die algehele telling deur die eksperimentele groep op die M-ABC na die agt weke deelname. Handvaardigheid het beduidend verbeter (p=.035). Daar was „n tendens vir balvaardighede om te verbeter (p=0.88), maar geen verbetering was aangedui vir balans na die ingryping nie. Die PEGS resultate was moeilik om te interpreteer aangesien die deelnemers hulself as baie vaardig gesien het ten spyte van hulle vermoëns. Gevolgtrekking: Die resultate van hierdie studie ondersteun die hipotese dat 'n doelgerigte groepsoefeningsprogram wel die grofmotoriese vaardighede van kinders met „n diagnose van DCD verbeter. Fisioterapeute kan 'n groepsofeningsprogram met vertroue implementeer waar 'n tekort aan menslike hulpbronne een tot een terapie beperk.

Thesis (M Sport Sc (Sport Science))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The purpose of the study was to analyse the penalty area entrances of a team competing in the Premier Soccer League (PSL) in South Africa. Ten home matches of the team were analysed making use of a category set designed for the study. The main areas of analysis included the point of final action before the ball entered the penalty area, the part of the penalty area at which the entrance occurred, the method of entrance, the number of completed passes within the area, and the outcome of the entrance as well as the reason for the outcome. The results revealed that the team entered the penalty area on average 59.4 times per match and scored a goal on every 37.4 penalty area entrances. The ball being taken away by the opponents was the outcome that occurred most frequently within the penalty area (42.1% of all entries), and was largely due to interceptions by the defending team (20.7%). The next most commonly occurring event was the ball being given away by the attacking team (22.4% of all entries) and was largely as a result of the poor passing (20%). The results revealed that in order for the team to improve their ability to convert their attacking opportunities into goals, improvement of technical execution in particular passing and shooting within the critical areas of the field must be established. The results have implications for the use of performance analysis for professional teams as support for the coaching process. / AFRIKAANSE OPSOMMING: Die doel van die studie was om „n prestasie-profiel te ontwikkel wat die strafarea-toegang beskryf van „n professionele span wat aan die Premier Sokker Liga (PSL) in Suid-Afrika deelneem. Tien tuiswedstryde van die span is geanaliseer, gebaseer op „n kategorie wat vir die studie ontwerp is. Die vlakke van analise was eerstens die punt van finale aksie voordat die bal die strafarea binnegaan, die plek in die strafarea waar toegang plaasgevind het, die metode van toegang, die hoeveelheid afgehandelde aangee-aksies in die area en laastens die uitkoms van die toegang asook die rede vir die uitkoms. Die resultate het aangedui dat die span die strafarea ongeveer 59.4 keer per wedstryd betree en elke 37.4 „n doel aanteken deur toegang tot die strafarea te verkry. Die afneem van die bal deur „n span (42.1% van toegang) het die meeste plaasgevind nadat die bal die strafarea binne gegaan het. Dit is grotendeels te wyte aan onderskepping deur die verdedigende span (20.7%). Die weggee van die bal deur die aanvallende span (22.4% van toegang) was hoofsaaklik as gevolg van swak aangee-aksies (20%) en het ook dikwels voorgekom. Die prestasie-profiel het aangedui dat indien die span hulle vermoë wil verbeter om aanvallende geleenthede te laat eindig in „n doel, verbetering nodig is met tegniese uitvoering, veral met vaardighede ten opsigte van „n bal-aangee en doelskop. Hierdie studie is „n voorbeeld van hoe prestasie-analise aangewend kan word in professionele sokker om ondersteuning aan die afrigtingsproses te bied.

Internships are commonly used by firms for training and recruiting talents. Yet, research overlooks which factors are influential in job acceptance for interns. The purpose of this study is to investigate the relationship of influencing factors such as task goal clarity, autonomy, mentorship and learning to job acceptance of interns after an internship program. A total of 150 copies of questionnaires were distributed online among university and graduate school students in Taiwan. 120 questionnaires were returned. The statistical methods used in this study were reliability test, descriptive analysis, correlation analysis and regression analysis. Based from the results shown, it was found that task goal clarity and mentorships influences the learning of interns. Furthermore, autonomy affects the relationship of task goal clarity and learning. The relationship of task goal clarity and learning is expected to be stronger when autonomy is high and weaker when it is low. Lastly, learning influences the willingness of job acceptance. The recommendations from the conclusions are proposed as references for relevant organizations and future studies Keywords: task goal clarity, mentorship, autonomy, learning, job acceptance, internships / Internships are commonly used by firms for training and recruiting talents.

The objectives of this thesis are: (1) to investigate the antecedents and consequences of fairness of performance evaluation processes (procedural fairness) in the context of performance measurement, evaluation, and reward systems; and (2) to investigate the behavioural effects of reliance on multiple performance measures (RMPM) in evaluating subordinates' performance. In relation to the first objective, it examines whether managers' perceptions of procedural fairness are influenced by the form (financial or nonfinancial) of performance measures used to evaluate performance, and by goal-related variables such as participation in setting performance targets, the goal-attainment-reward link, and the specificity of goals to be achieved by managers. With regard to the consequences of procedural fairness, it examines the effects of procedural fairness on job satisfaction, performance, organisational commitment, and goal commitment, and also examines whether any such associations are direct or indirect. In relation to the second objective, it examines whether RMPM affects managerial performance or whether the effect is contingent on goal difficulty and goal specificity. To address these objectives, this thesis draws on organisational justice theory and goal theory and employs both quantitative and qualitative approaches. Quantitative data are collected using a questionnaire survey sent to managers in four organisations and qualitative data are gathered by means of interviews and focus group discussions within the organisations. The results indicate that procedural fairness is affected by participation in setting performance targets, the goal-attainment-reward link, and the specificity of goals to be achieved by managers, but not by the type of performance measure used to evaluate performance. With regard to the consequences of procedural fairness, the results indicate that: (1) the effects of procedural fairness on job satisfaction and performance are indirect and fully mediated by distributive fairness, trust, and organisational commitment; (2) the effect of procedural fairness on organisational commitment is partially mediated by distributive fairness and trust; and (3) the effect of procedural fairness on goal commitment is partially mediated by trust. Finally, the results indicate that the effect of RMPM on performance is contingent on goal specificity, but not on goal difficulty.
