Abstract:

Previous research has shown that most antihistamines have sedative effects and can lead to deterioration of psychomotor performance. The objective of this research was to determine if two antihistamines (diphenhydramine and astemizole) administered at a therapeutic dose level will affect a subject's visual search capabilities. The results of this research indicate that astemizole did not significantly decrement a subject’s ability to visually search as compared to the performance of that same subject after ingesting a placebo. Diphenhydramine produced significantly poorer visual search results than did astemizole.

This paper addresses issues raised by the ever-expanding role of email as a multi-faceted application that combines communication, collaboration, and task management. Individual differences analysis was used to contrast two email user interfaces in terms of their demands on users. The results of this analysis were then interpreted in terms of their implications for designing more inclusive interfaces that meet the needs of users with widely ranging abilities. The specific target of this research is the development of a new type of email message representation that makes pending tasks more visible. We describe a study that compared a new way of representing tasks in an email inbox, with a more standard representation (the Microsoft Outlook inbox). The study consisted of an experiment that examined how people with different levels of three specific cognitive capabilities (flexibility of closure, visual memory, and working memory) perform when using these representations. We then identified combinations of representation and task that are disadvantageous for people with low levels of the measured capabilities.

Task based language instruction has generated some debate among researchers. Some argue in favour of task based language instruction by claiming that tasks focus learners' attention on meaning and thus facilitate second language acquisition (Prahbu, 1987; Pica and Doughty, 1986; Pica, Kanagy, and Falodun,1993). Others argue against task based language instruction and call into question the concept of comprehensible input, the idea upon which the whole task based approach is based (Sheen, 1994).

Abstract:

Research in swarm robotics focuses mostly on how robots interact and cooperate to perform tasks, rather than on the details of task execution. As a consequence, researchers often consider abstract tasks in their experimental work. For example, foraging is often studied without physically handling objects: the retrieval of an object from a source to a destination is abstracted into a trip between the two locations---no object is physically transported. Despite being commonly used, so far task abstraction has only been implemented in an ad hoc fashion.

In this dissertation, I propose a collection of tools for flexible and reproducible task abstraction. At the core of this collection is a physical device that serves as an abstraction of a single-robot task to be performed by an e-puck robot. I call this device the TAM, an acronym for "task abstraction module". A complex multi-robot task can be abstracted using a group of TAMs by first modeling the task as the set of its constituent single-robot subtasks and then representing each subtask with a TAM. I propose a novel approach to modeling complex tasks and a framework for controlling a group of TAMs such that the behavior of the group implements the model of the complex task.

The combination of the TAM, the modeling approach, and the control framework forms a collection of tools for conducting research in swarm robotics. These tools enable research on cooperative behaviors and complex tasks with simple, cost-effective robots such as the e-puck - research that would be difficult and costly to conduct using specialized robots or ad hoc solutions to task abstraction. I present proof-of-concept experiments and several studies that use the TAM for task abstraction in order to illustrate the variety of tasks that can be studied with the proposed tools.

Full text

Abstract:

The first step in developing or updating a licensure or certification examination is to conduct a job or task analysis. Following completion of the job analysis, a survey validation study is performed to validate the results of the job analysis and to obtain task ratings so that an examination blueprint may be created. Psychometricians and job analysts have spent years arguing over the choice of scales that should be used to evaluate job tasks, as well as how those scales should be combined to create an examination blueprint. The purpose of this study was to determine the relationship between individual and composite rating scales, examine how that relationship varied across industries, sample sizes, task presentation order, and number of tasks rated, and evaluate whether examination blueprint weightings would differ based on the choice of scales or composites of scales used. Findings from this study should be used to guide psychometricians and job analysts in their choice of rating scales, choice of composites of rating scales, and how to create examination blueprints based upon individual and/or composite rating scales. A secondary data analysis was performed to help answer some of these questions. As part of the secondary data analysis, data from 20 survey validation studies performed during a five year period were analyzed. Correlations were computed between 29 pairings of individual and composite rating scales to see if there were redundancies in task ratings. Meta-analytic techniques were used to evaluate the relationship between each pairing of rating scales and to determine if the relationship between pairings of rating scales was impacted by several factors. Lastly, sample examination blueprints were created from several individual and composite rating scales to determine if the rating scales that were used to create the examination blueprints would ultimately impact the weighting of the examination blueprint. The results of this study suggest that there is a high degree of redundancy between certain pairs of scales (i.e., the Importance and Criticality rating scale are highly related), and a somewhat lower degree of redundancy between other rating scales; but that the same relationship between rating scales is observed across many variables, including the industry for which the job analysis was being performed. The results also suggest the choice of rating scales used to create examination blueprints does not have a large effect on the finalized examination blueprint. This finding is especially true if a composite rating scale is used to create the weighting on the examination blueprint.

Le, Gallais Judy. "Performance of able and disabled readers on tasks of intra- and inter-modal haptic and visual processing." Thesis, McGill University, 1988. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=75852.

Full text

Abstract:

This research consisted of three individual studies, examining intra- and inter-modal haptic and visual processing in able learners and reading disabled children spanning the elementary school grades.
Performance was measured in terms of: accuracy scores, haptic exploration scores, and exploration times. Higher scores were obtained on the intra-modal visual condition than on any of the conditions involving a haptic component. Increasing the exploration times for haptic stimuli did not significantly improve performance on tasks involving a haptic component.
Performance scores of poor readers were depressed on all tasks, suggesting a general deficit in sensory processing rather than an inter-sensory processing deficit. Poor readers further employed less sophisticated haptic exploration strategies than able readers, suggesting use of less efficient task strategies.

Abstract:

The current study compared the performance of six commonly used cursor devices (absolute touchpad, mouse, trackball, relative touchpad, force joystick, and displacement joystick) on three types of tasks (target acquisition, text editing, and graphics). Prior to these comparisons, each of the devices was optimized for display/control dynamics in independent experiments. A total of 30 subjects were used in the five optimization studies. For each device, the optimization experiment compared a range of control dynamics using a target acquisition task (i.e., positioning a cross-hair cursor over square targets of varying sizes and screen distances). An analysis of variance procedure was used to determine the best control dynamics, of the range studied, for each device. Performance was based on a time-to-target (TT) measure. A comparison of the six optimized devices was then performed on the three task environments. For the target acquisition, text editing, and graphics tasks, a total of 12, seven, and six subjects were required, respectively. For the target acquisition study, the six devices were compared on a task identical to the optimization task; that is, cursor positioning performance for various target sizes and distances. In addition to the TT dependent measure, bipolar scale and subjective rank data were also collected. The text editing task required subjects to perform document correction on the computer using each of the six devices, with cursor keys added as a baseline device. Task completion time (TCT), bipolar scale response, and subjective rank data were collected. For the graphics task, subjects were required to perform basic graphics editing tasks with the six devices. As with the text editing task, TCT, bipolar scale, and rank data were collected. Results indicated a wide variation in the cursor positioning performance of the devices on the three tasks. Without exception, the mouse and trackball performed the best of the six devices, across all tasks. In addition, these devices were most preferred. In general, the two joysticks performed worse on the target acquisition and graphics tasks than the two touchpads. On the text editing task, however, the rate—controlled joysticks performed better than the touchpads.

Mendez, Elizabeth Tamez. "Leadership Development among Youth in Latino Congregations| The Relationship of Religious Participation to Social Service Involvement and Engagement in Leadership Tasks." Thesis, Andrews University, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10973409.

Full text

Abstract:

Personal observations and anecdotal accounts attest that some of the young people in U.S. Latino churches are developing as leaders within their congregations. This seems to come as a result of the organic or less-formalized leadership development dynamics and practices present within Latino congregations, where leaders often develop by being actively involved in leadership actions without necessarily first following a curriculum of study, completing a training program, or fulfilling a set of theological education requirements. In this way, many are acquiring roles and responsibilities by which they actively contribute towards local congregational and community life, and by which they develop as leaders through hands-on experiences. This less formalized leadership development dynamic in Latino congregations has yet to be empirically studied, as a means to further understand and learn from this unique characteristic that can be helpful to the church at large in our search for how to develop the next generation of leaders. Thus, there is a need to identify, describe, and empirically analyze some of the specific phenomena involved in these observed dynamics within Latino congregations that seem to be contributing towards youths’ leadership development.

Method: Therefore, this descriptive and explanatory ex post facto study examined key congregational practices within Latino churches and the level of participation young people have in these as a means of analyzing the association of both with leadership development. The study drew on existing data collected through the Chicago Latino Congregational Study – Youth Survey (CLCS–YS) of 63 randomly sampled Latino congregations in different Christian denominations: Catholic, Evangelical, Mainline, and Pentecostal. The sample population consisted of 307 Latino youth ages 13 to 19.

After examining the 104 questionnaire items of the CLCS–YS for applicability, 23 were selected to analyze youth’s religious participation, social service involvement, and engagement in leadership tasks, while controlling for demographic characteristics. Aspects of Positive Youth Development (PYD) theory pertaining to youth leadership development provided a means to select and create the variables studied, which were derived from socioreligious descriptions of Latino congregations that are linked to the aforementioned organic leadership dynamics.

Results: The data analysis revealed that youth in Chicago Latino congregations have a high aggregate score for both Religious Participation and Engagement in Leadership Tasks, and both scores increase with their age. Although their aggregate score for Social Service Involvement was found to be low, the frequencies of the reported habits, actions, and behaviors regarding Social Service Involvement indicate that a high percentage of youth are involved in volunteering or social service in and out of their local congregation. A significant relationship was also found between youths’ level of Religious Participation and their level of Social Service Involvement and Engagement in Leadership Tasks, with both scores increasing as their scores in Religious Participation increased.

The results of the individual survey frequencies served to create a contextual description of socioreligious phenomena present in Chicago Latino congregations, as well as a wider reference into the religious habits of Latino youth. The findings support the observations and anecdotal accounts regarding the level of engagement youth have with organic dynamics for leadership development in Latino congregations. Based on PYD theory, the study also provided a proposed set of variables and measurements by which to approach future studies on this topic. Youth congregants are involved in hands-on experiences such as social service projects and exercising leaderships tasks, and they are also engaging very frequently with their supportive religious community. These are all characteristics of ecological contributing contexts which PYD postulates can potentially contribute towards the leadership development of youth, and their continued contribution as leaders in adulthood (Avolio & Vogelgesang, 2011; Murphy & Reichard, 2011).

Abstract:

Stress-related cognitive changes are still a matter of debate. In some particular neuropathological conditions such as focal ischemia, cognitive functions have been shown to be significantly impaired. These conditions, however, may be improved by some factors such as steroid hormones. The purpose of the current thesis was to assess the structural and functional effects of corticosterone-related experiences on the hippocampus before and after endothelin-1 (ET-1)-induced stroke. We found corticosterone-related experiences enhance the hippocampal recovery, and improve its function in both wet and dryland tasks after ET-1-induced focal stroke. Structural and functional effects of such experiences prior to the focal ischemia in the hippocampus, however, showed that stress, not corticosterone is a strong inhibitor for hippocampal recovery.

Abstract:

It was hypothesized that 192 IgG-saporin lesions of the basal forebrain cholinergic system (BFCS) would disrupt differential reinforcement of low rate (DRL) learning in an uncued DRL task, but would not impair acquisition and performance in the cued version of the task. Results suggest that BFCS lesions impair vigilance to the external cues despite continued practice in the cued DRL, whereas continuous attention to internally produced cues recovers with extended practice in the uncued DRL.

Abstract:

Task has been recognized as an influential factor in information seeking behavior. An increasing number of studies are concentrating on the specific characteristics of the task as independent variables to explain associated information-seeking activities. This paper examines the relationships between operational measures of information search behavior, subjectively perceived post-task difficulty and objective task complexity in the context of factual information-seeking tasks on the web. A questiondriven, web-based information-finding study was conducted in a controlled experimental setting. The study participants performed nine search tasks of varying complexity. Subjective task difficulty was found to be correlated with many measures that characterize the searcherâ s activities. Four of those measures, the number of the unique web pages visited, the time spent on each page, the degree of deviation from the optimal path and the degree of the navigation pathâ s linearity, were found to be good predictors of subjective task difficulty. Objective task complexity was found to affect the relative importance of those predictors and to affect subjective assessment of task difficulty.

Abstract:

The purpose of this study was to evaluate the effectiveness of teaching self-instructional skills to navigate to a mobile device to access video prompts to teach novel behaviors to two adults with autism spectrum disorder (ASD) in a vocational setting. This study used a multiple probe across conditions design to evaluate effectiveness. In baseline, the researcher directed the participants to complete a novel task and collected data on correct steps completed. In technology training the researcher used a system of least prompts procedure to teach participants to initiate the use of the mobile device, navigate to an app, navigate to the specific behavior schedule, watch video prompt, navigate to the next step, and complete the modeled behaviors. After mastery of technology training, researcher evaluated performance of novel tasks following self-instruction to access video prompts on the mobile device. Participant’s fidelity of navigation skills was assessed, however was not included in mastery criterion. Both participants learned to self-instruct to independently access video prompts on a mobile device. One participant self-instructed using the mobile device and video prompts to correctly complete novel tasks.

Abstract:

L'enseignement/apprentissage du français au lycée scientifique en Italie. Pratiques de classe et création de supports appropriés.Cette thèse porte sur l'étude des langues vivantes étrangères dans les établissements du secondaire en contexte italophone. L'objectif de ce travail a été de mener une réflexion sur l'enseignement/apprentissage du français au lycée scientifique, tout en focalisant l'attention sur l'attitude des apprenants face à des tentatives d'initiation à la langue de spécialité complémentaires au développement des programmes scolaires consacrés, notamment, à l'histoire littéraire. Nous avons émis l'hypothèse générale stipulant qu'« il est possible d'envisager l'organisation de séances au cours desquelles l'apprenant, s'exprimant en français, se livre à des tâches susceptibles de le motiver, lui permettant de connaître le discours et le milieu d'action propres aux futurs professionnels dans le domaine scientifique et médical ».L'hypothèse en objet a été testée par le biais d'une recherche-action qui a eu lieu en contexte institutionnel. Cette approche a été fondée sur l'utilisation de tâches, choisies/conçues selon le niveau des apprenants, liées surtout à des situations auxquelles les destinataires étaient susceptibles de se confronter dans la vie de tous les jours. La presque totalité du travail a été effectuée grâce à l'emploi des TIC.Les résultats ont prouvé l'efficacité de la recherche de terrain et en ont témoigné l'appréciation de la part des jeunes apprenants concernés. Par conséquent, l'ambition de cette thèse est de contribuer à nourrir le débat sur l'utilité de l'étude de deux langues vivantes étrangères dans les établissements du secondaire italiens, en harmonie avec les dispositions du Conseil de l'Europe, de même que de dégager les étapes d'un cheminement éducatif menant à l'acquisition des habiletés linguistiques nécessaires lors de séjours d'études/de travail en pays francophones pendant les années à venir
This Thesis deals with the study of foreign languages within the Italian High School System.The goal of this work is to draw the attention to the way of teaching/learning French at High School (option maths and science), focusing on the students' attitude while learning a second foreign language, as well as to outline some new educational tools likely to replace the old fashioned ones still in use.In order to achieve this goal, we examined and tested a general hypothesis, stipulating whether “it is possible to set up sessions during which the learner is involved in seemingly motivating activities, and, while expressing himself in French, manages to learn the language and environment of a specific field, familiar to his future professional scientific and medical world”. Such hypothesis was tested following up an experimental action research, that took place within an institutional context. This approach was supported by targeted assignments, based on everyday life situations, then given to the students according to their level of knowledge of the language. Most of the work was carried on thanks to TIC. The results confirmed the effectiveness of the research on this ground, and showed the appreciation of some of the young participants. Consequently, the aim of this Thesis is to contribute to the discussion concerning the need of studying two foreign languages at the Italian High School, in line with the dispositions given by the Counsel of Europe, as well as to follow the steps of the educational training leading students to acquire all the language skills to study or work abroad

Abstract:

This thesis traces the inception and evolution of a combined collaborative action research project and living theory action research project. Six academic staff members attempted to improve our practice of generating locally relevant research in a university psychology clinic. This process impacted not only on the lives of the participants, but facilitated the enactment of the three tasks of universities and so influenced the lives of the student and residential communities to whom we had a responsibility. This thesis explores two research questions that formed the first part of the study, namely: “How can we improve the functioning of Itsoseng Psychology Clinic?” and “How can we increase our research output?” The second part of the study was a self-study action research project in which I examined my attempts to improve my academic practice by inquiring into my practice of facilitating the collaborative action research project as a peer support initiative. In the form of my living theory, this thesis therefore also explored my answers to the questions: “How can I facilitate a peer support research initiative?” and “How can I improve my academic practice through facilitating such an initiative?” I take a macro-level view of the relationship between a university and surrounding communities and discuss within the South African context three discernable mandates or tasks that universities fulfil: teaching, research and community engagement. I discuss the relevance of this study to psychology and specifically university psychology clinics as potential interface between the university and the surrounding community when enacting community engagement as the third academic task. I also discuss the implications of this study to action research methodology and the concept of transformation in emancipatory research. The main argument of my living theory of my academic practice is that the formation and nurturing of a regular, supportive and critical audience in the form of peer support research meetings contributed to the transformation of resources into assets when we worked towards improving the service delivery and local relevance of a university psychology clinic.

Abstract:

This licentiate thesis addresses what textbooks in the school subject Swedish specifically oriented to pupils in different vocational programmes at Swedish high school/ upper secondary schools (Gymnasiet) offer to their readers. The study uses qualitative textual analysis as its main approach as well as, to a certain extent, quantitative data from textbooks in the Blickpunkt series (Blickpunktserien). Since they are included in so called comprehensive teaching materials, Bra Svenska A and Bra Svenska B, certain aspects of these two books, primarily their selection of texts are also studied. My point of departure is that a given textbook presumes a certain type of reader – this is supported by Umberto Eco’s theory that an author always writes with a reader in mind, a model reader, and I pose the following question: What views on subject matter, literature and cognitive approach are conveyed by the textbooks and what does this tell us about their model readers? My interpretation is that there are both many similarities and many differencies between the various model readers presumed by the textbooks. The focus on future professional activities permeates all of the textbooks, but is somewhat less prominent in Blickpunkt bygg and Blickpunkt el, where, to a certain extent, the model reader is presumed to be working with topics which can be attributed to the Swedish subject matter area. In Blickpunkt barn och fritid, Blickpunkt fordon, Blickpunkt hotell och restaurang and Blickpunkt omvårdnad, the postulated reader is assumed to be uninterested in literature and is expected to work in a field only marginally related to the Swedish subject matter area. Instead the textbooks are organized on the basis of a general assumption regarding what know-how and qualifications are currently in demand on the labor market. Therefore we cannot say that they contain a genuine Swedish subject matter area. The formulation of the textbooks implies that a model reader is not expected to approach the texts with a critical mind in order to help him or her develop cognitive thinking and oral and written language skills.

O Job Shop é um dos sistemas mais conhecidos e estudados, pois reúne características de outras classes de sistemas de planejamento, além de ser necessária a elaboração de métodos de resolução mais sofisticados devido sua alta complexidade (NP-difícil). A computação natural é constituída por novas abordagens de computação caracterizadas por uma maior proximidade com a natureza. A aplicação de métodos inspirados em sistemas imunológicos demonstra, nos últimos anos, ser promissor em diversas áreas de aplicação e pesquisa, como por exemplo, otimização. Tendo em vista este cenário, é feita aqui uma abordagem imuno-inspirada para elaboração de um sistema de otimização, através de resolução do escalonamento de um Job Shop, provendo soluções diversificas e de alta qualidade
Abstract: Scheduling problems are jobs allocation using distinct sources ordered by sequence constraint and time constraint. Job Shop is one the most studied problem because it is possible to find different scheduling features. Also this problem needs sophisticated solving methods by complexity characteristics (NP-Hard). Natural Computing uses a new computation approach representing natural systems. Immune system methods approaches shows, in the last years, good results in many applications and several researches, for example, optimization. In this scenario we developed an artificial immune system to solve Job Shop system. We will show hight diversity and quality solutions

Abstract:

Ce travail de thèse de doctorat est dédié à l'étude d'un problème de placement de tâches dans le domaine de la compilation d'applications pour des architectures massivement parallèles. Ce problème vient en réponse à certains besoins industriels tels que l'économie d'énergie, la demande de performances pour les applications de type flots de données synchrones. Ce problème de placement doit être résolu dans le respect de trois critères: les algorithmes doivent être capable de traiter des applications de tailles variables, ils doivent répondre aux contraintes de capacités des processeurs et prendre en compte la topologie des architectures cibles. Dans cette thèse, les tâches sont organisées en réseaux de communication, modélisés sous forme de graphes. Pour évaluer la qualité des solutions produites par les algorithmes, les placements obtenus sont comparés avec un placement aléatoire. Cette comparaison sert de métrique d'évaluation des placements des différentes méthodes proposées. Afin de résoudre à ce problème, deux algorithmes de placement de réseaux de tâches de grande taille sur des architectures clusterisées de processeurs de type many-coeurs ont été développés. Ils s'appliquent dans des cas où les poids des tâches et des arêtes sont unitaires. Le premier algorithme, nommé Task-wise Placement, place les tâches une par une en se servant d'une notion d'affinité entre les tâches. Le second, intitulé Subgraph-wise Placement, rassemble les tâches en groupes puis place les groupes de tâches sur les processeurs en se servant d'une relation d'affinité entre les groupes et les tâches déjà affectées. Ces algorithmes ont été testés sur des graphes, représentants des applications, possédant des topologies de types grilles ou de réseaux de portes logiques. Les résultats des placements sont comparés avec un algorithme de placement, présent dans la littérature qui place des graphes de tailles modérée et ce à l'aide de la métrique définie précédemment. Les cas d'application des algorithmes de placement sont ensuite orientés vers des graphes dans lesquels les poids des tâches et des arêtes sont variables similairement aux valeurs qu'on peut retrouver dans des cas industriels. Une heuristique de construction progressive basée sur la théorie des jeux a été développée. Cet algorithme, nommé Regret Based Approach, place les tâches une par une. Le coût de placement de chaque tâche en fonction des autres tâches déjà placées est calculée. La phase de sélection de la tâche se base sur une notion de regret présente dans la théorie des jeux. La tâche qu'on regrettera le plus de ne pas avoir placée est déterminée et placée en priorité. Afin de vérifier la robustesse de l'algorithme, différents types de graphes de tâches (grilles, logic gate networks, series-parallèles, aléatoires, matrices creuses) de tailles variables ont été générés. Les poids des tâches et des arêtes ont été générés aléatoirement en utilisant une loi bimodale paramétrée de manière à obtenir des valeurs similaires à celles des applications industrielles. Les résultats de l'algorithme ont également été comparés avec l'algorithme Task-Wise Placement, qui a été spécialement adapté pour les valeurs non unitaires. Les résultats sont également évalués en utilisant la métrique de placement aléatoire
This Ph.D thesis is devoted to the study of the mapping problem related to massively parallel embedded architectures. This problem arises from industrial needs like energy savings, performance demands for synchronous dataflow applications. This problem has to be solved considering three criteria: heuristics should be able to deal with applications with various sizes, they must meet the constraints of capacities of processors and they have to take into account the target architecture topologies. In this thesis, tasks are organized in communication networks, modeled as graphs. In order to determine a way of evaluating the efficiency of the developed heuristics, mappings, obtained by the heuristics, are compared to a random mapping. This comparison is used as an evaluation metric throughout this thesis. The existence of this metric is motivated by the fact that no comparative heuristics can be found in the literature at the time of writing of this thesis. In order to address this problem, two heuristics are proposed. They are able to solve a dataflow process network mapping problem, where a network of communicating tasks is placed into a set of processors with limited resource capacities, while minimizing the overall communication bandwidth between processors. They are applied on task graphs where weights of tasks and edges are unitary set. The first heuristic, denoted as Task-wise Placement, places tasks one after another using a notion of task affinities. The second algorithm, named Subgraph-wise Placement, gathers tasks in small groups then place the different groups on processors using a notion of affinities between groups and processors. These algorithms are tested on tasks graphs with grid or logic gates network topologies. Obtained results are then compared to an algorithm present in the literature. This algorithm maps task graphs with moderated size on massively parallel architectures. In addition, the random based mapping metric is used in order to evaluate results of both heuristics. Then, in a will to address problems that can be found in industrial cases, application cases are widen to tasks graphs with tasks and edges weights values similar to those that can be found in the industry. A progressive construction heuristic named Regret Based Approach, based on game theory, is proposed. This heuristic maps tasks one after another. The costs of mapping tasks according to already mapped tasks are computed. The process of task selection is based on a notion of regret, present in game theory. The task with the highest value of regret for not placing it, is pointed out and is placed in priority. In order to check the strength of the algorithm, many types of task graphs (grids, logic gates networks, series-parallel, random, sparse matrices) with various size are generated. Tasks and edges weights are randomly chosen using a bimodal law parameterized in order to have similar values than industrial applications. Obtained results are compared to the Task Wise placement, especially adapted for non-unitary values. Moreover, results are evaluated using the metric defined above

Abstract:

Despite extensive research into the concept of mental fatigue there is as yet no “gold standard” definition or measurement technique available. Because of this a large amount of fatigue-related errors are still seen in the workplace. The complexity of the problem lies with the inability to directly measure mental processes as well as the various endogenous and exogenous factors that interact to produce the experienced fatigue. Fatigue has been divided into sleep-related and task-related fatigue; however the task-related aspect is evident both during normal waking hours as well as during periods of sleep deprivation, therefore this aspect is considered important in the understanding of fatigue in general. The concept of task-related fatigue has further been divided into active and passive fatigue states; however differentiation between the two requires careful consideration. Various physiological measures have been employed in an attempt to gain a better understanding of the mechanisms involved in the generation of fatigue, however often studies have produced dissociating results. The current study considered the task-related fatigue elicited by a tracking task requiring sustained attention, in order to evaluate the usefulness of various cardiovascular and oculomotor measures as indicators of fatigue. A secondary aim was to determine whether the behavioural and physiological parameter responses could be used to infer the type of fatigue incurred (i.e. an active versus passive fatigue state) as well as the energetical mechanisms involved during task performance. A simple driving simulator task was used as the main tracking task, requiring constant attention and concentration. This task was performed for approximately two hours. Three experimental groups (consisting of 14 subjects each) were used: a control group that performed the tracking task only, a group that performed a five minute auditory memory span task concurrently with the driving task after every 20 minutes of pure driving, and a group that performed a visual choice reaction task for five minutes following every 20 minute driving period. The secondary tasks were employed in order to evaluate the extent of resource allocation as well as arousal level. Performance measures included various driving performance parameters, as well as secondary task performance. Physiological measures included heart rate frequency (HR) and various time- and frequency-domain heart rate variability (HRV)parameters, pupil dilation, blink frequency and duration, fixations, and saccadic parameters as well as critical flicker fusion frequency (CFFF). The Borg CR-10 scale was used to evaluate subjective fatigue during the task, and the NASA-TLX was completed following the task. A decline in driving performance over time was supplemented by measures such as HR, HRV and pupil dilation indicating an increase in parasympathetic activity (or a reduction in arousal). An increase in blink frequency was considered as a sign of withdrawal of attentional resources over time. Longer and faster saccades were also evident over time, coupled with shorter fixations. With regards to the secondary task influence, the choice RT task did not affect any behavioural or physiological parameters, thereby contesting the active fatigue theory of resource depletion, as well as implying that the increase in demand for the same resources used by the primary task was insufficient to affect the state of the subjects. The increased load elicited by the memory span task improved driving performance and increased measures of HR, HRV, pupil dilation and blink frequency. Some of these measures produced opposite effects to what was expected; an attempt to explain the dissociation of the various physiological parameters was expressed in terms of arousal, effort and resource theories. Overall, the results indicate that the fatigue and/or reduced arousal accompanying a monotonous sustained attention task can, to some degree, be alleviated through intermittent performance of a secondary task engaging mental resources other than the ones used for the primary task. The degree to which such a task is beneficial, however, requires careful consideration as while an immediate increase in arousal and primary task performance is noted, the impact of the task on general attentional resources may be detrimental in the case of reacting should an emergency situation occur.

Abstract:

This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires.

Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.

The results show large differences between the two language groups in respect to time for solving the two tasks. For the construction task, these were mainly due to different communication strategies used for error handling. In the sorting task a clear learning effect can be observed for the L2-groups which, in effect, makes the L2 users solve the sorting task almost as fast as the L1 groups, after an initial learning period. However, the informants in the L2 groups generally referred to the objects used in this task by describing peripheral characteristics of these objects. They also showed more signs of uncertainty and hesitation in the actual dialogue situation. However, no differences in error frequency could be found between the two language groups.

Differences in role-taking between the language groups were also made apparent in the study. These differences became especially clear for the L2 groups in the construction task.

Abstract:

Notre étude relève du domaine de la didactique des langues et plus particulièrement sur la focalisation sur l’utilisation des présentations PowerPoint pour les réalisations des tâches. Ces dernières jouent un rôle important dans le déclenchement de processus d’apprentissage. Lorsque les apprenants réalisent des tâches sur support PowerPoint,interagissent ensemble pour construire du sens, ils sont dotés d’un statut d’acteurs sociaux.Cette étude se donne alors comme objectif d’améliorer la pratique des apprenants en classe et de résoudre certaines de leurs difficultés didactiques et pédagogiques à travers un dispositif hybride. Celui-ci est fondé sur des macro-tâches réalisées majoritairement en semi distance et mise en place majoritairement en présentiel à travers des exposés techniques. Ces derniers ont été conçus pour encourager le développement de performances langagières attendues en production orale des apprenants.Elle se base sur une recherche-action qui a été menée en Ouganda pour des apprenants anglophones qui apprennent le français comme langue étrangère à Makerere UniversityBusiness School (MUBS) à Kampala. Cette étude a porté sur un exposé technique oral parles apprenants du Français sur Objectif Spécifique (FOS) à (MUBS) en Ouganda.Cette recherche-action vise à améliorer l’expression orale en FOS des apprenants de l’université MUBS. Nous avons donc menée des multiples expérimentations qui nous ont permises dans un premier temps de questionner l’impact d’un exposé oral des tâches réelles collectivement élaborée et présentée sur support Power Point sur la production orale de ces apprenants. Ces tâches avaient comme objectif d’encourager les apprenants de transformer un texte en titre, sous-titres et paragraphes, puis de présenter leur travail sous forme de diaporama avec PowerPoint. Le but était d’éviter la lecture linéaire de l’exposé,afin d’accroître leur confiance en eux-mêmes et dans l’interaction en FOS. Grâce à la recherche-action, nous avons pu définir précisément en quoi et pourquoi les choix de nos tâches, de nos activités devraient avoir un effet positif sur notre public cible
The initial objective of this study, which lies within the field of language teaching andespecially on the role of information and Communication Technology (ICT), is to investigate the potential of ICT in triggering oral language development in the learners of French for Specific purposes (FSP) at Makerere University Business School. This studyadopts action research that focuses on the role of technologies deployed in oral technical presentations of macro-tasks such as the use of MS Office. The aim is to enhance Frenchlearners’ skills in French for Specific purposes. The social constructivist or cultural hypotheses posit that social interaction plays an important role in L2 acquisition (French in this case) in FSP classes through a hybrid environment based on macro-tasks performed indistance and presented in class.The current action research project involved identifying and putting into place a learningsystem for learners of FSP who experienced several difficulties with their spoken French inthe learning process. It further posits that learners construct the new language through socially mediated interaction. Subsequently, this involved establishing whether the use ofPowerPoint presentation (PPP) would engage learners of FSP in collective actions both inthe classroom and in the real world activities. In addition, there was an attempt to establishif relevant web quest materials were likely to enhance oral language acquisition and prompt learners to take responsibility for their own learning

Anecdotal evidence suggests that sleep can aid in creative performance, but few studies have systematically investigated this association. Prior research suggests that creative thinking, particularly divergent cognition, is similar to mental states found in sleep and dreaming, especially during REM sleep. Studies have found that sleep benefits general learning and problem-solving, and facilitates insight that promotes enhanced performance on cognitive tasks. This study investigated the effects of sleep on performance with verbal and visual tasks that explicitly require creative ability. I hypothesised that participants with a period of sleep between task preparation and execution would perform better than participants with an equal period of REM-deprived sleep, daytime wakefulness, or no interval between preparation and execution, but there would be no difference in performance between the participants in terms of convergent cognition. The study was a 4-level, single-factor design, with state of consciousness as the manipulated variable. Participants (n = 87) were recruited from the university undergraduate population. Participants memorised a wordlist for task preparation and then, after an interval of either normal sleep, REM-deprived sleep, waking activity, or no interval, used the same wordlist to write a creative short story for task execution. The stories were assessed for creativity-related constructs by the researcher and independent raters. Participants also completed a visual design fluency task at both stages of the study, following a 4-level, single-factor, repeated-measures design. Participants' scores on the Torrance Test of Creative Thinking (TTCT) Verbal Edition and the Shipley Institute of Living Scale (SILS) were used to control for general creative ability and IQ respectively. ANCOVA, repeated measures ANOVA, and Fisher's r to z transformation statistics were used to analyse the data. Although generally the hypotheses were not directly supported by the data obtained, trends suggest that there was a connection between sleep and creativity, especially an apparent interaction between baseline creativity and the type of interval. Based on the indirect evidence obtained, directions for future research for investigating sleep and creativity are discussed.

The high school research paper is a task which consumes instructional time, requires considerable student effort, and places a high demand on school library resources. Little research has been conducted on how students accomplish this task. Academic task research indicates that in classrooms, tasks are defined by students in terms of (a) the nature of the products the teacher will accept and (b) the operations allowed and the resources available. Here the product is the research paper; the resources available include those found in the school library. The purpose of this study was to determine what strategies students use to perform the library-related task.

Abstract:

The effect of anxiety on motor learning during a balance relevant task was investigated. Twenty participants (mean age 22.0 ± 2.7 years) were randomly divided into groups that completed the task whilst standing directly on the platform or on 9cm high pedestals, thus constructing Non-Anxious (NA) or Anxious (A) environments. Participants trained for 36 trials in a continuous, pseudo-random oscillating balance task consisting of pseudo-random amplitude translation at 0.5Hz for 45 seconds each on Day 1 and returned for Retention and Transfer tests on Day 2. Motor performance was impaired by training in an anxious environment and this effect persisted across retesting in both non-anxious and anxious environments. Anxiety also tended to further impair transfer of motor performance improvements to a non-anxious environment. These findings have implications for the success of balance training programs in patients who are anxious or afraid of falling.

For many vehicles, obstacles, and targets, coordination of a fleet of Unmanned Aerial Vehicles (UAVs) is a very complicated optimization problem, and the computation time typically increases very rapidly with the problem size. Previous research proposed an approach to decompose this large problem into task assignment and trajectory problems, while capturing key features of the coupling between them. This enabled the control architecture to solve an assignment problem first to determine a sequence of waypoints for each vehicle to visit, and then concentrate on designing paths to visit these pre-assigned waypoints. Although this approach greatly simplifies the problem, the task assignment optimization was still too slow for real-time UAV operations. This thesis presents a new approach to the task assignment problem that is much better suited for replanning in a dynamic battlefield. The approach, called the Receding Horizon Task Assignment (RHTA) algorithm, is shown to achieve near-optimal performance with computational times that are feasible for real-time implementation. Further, this thesis extends the RHTA algorithm to account for the risk, noise, and uncertainty typically associated with the UAV environment. This work also provides new insights on the distinction between UAV coordination and cooperation. The benefits of these improvements to the UAV task assignment algorithms are demonstrated in several simulations and on two hardware platforms.

Abstract:

How people make sense of the world around them via the categories they use is a question that social science researchers frequently attempt to address through their investigations (e.g., Spradley, 1970). One prevalent approach in organizational research is the rep grid method (Reger, 1990). This technique, based upon Kelly's (1955) role construct repertory test, asks participants to sort items (e.g., people, recent events, or artifacts) within a three-member group into subgroups based on participant-defined similarity and dissimilarity. The researcher's main task, therefore, is to inquire about the characteristics or conditions that each participant uses to sort these itemsâ what is similar among the paired items and what makes the pair different from the item that is excluded. Reger (1990) remarks that such an approach creates conditions in which "the researcher's frame of reference and worldview would not be imposed upon the respondent" (301). In information and library science (ILS) research, individuals' uses of categories for sense-making are viewed as being closely coupled to their interactions with available information resources, services, or systems. Sorting tasks are one general class of methods used to uncover the categories that users employ during these interactions. In information systems research, Tan and Hunter (2002) discuss qualitative and quantitative applications of the rep grid method. While other sorting tasks in ILS research do not explicitly share the same intellectual lineage as the rep grid method, the general approaches and outcomes are largely consistent. Kwasnik (1991) studied how users classify personal documents based on criteria other than document attributes. She asked participants to provide a 'guided tour' of an office location along with a document sorting process, and, in reflection, she notes that "people are able to articulate the process by which...decisions were made, and the data produced by this articulation lend themselves to analysis at a level which can yield general rules about the behaviour" (389). The qualitative analysis from Kwasnik's (1991) study can be contrasted with quantitative analyses of sort data used for guidance in the design of information displays (Carlyle, 2001) and interoperable metadata schema (Tennis, 2003).The rep grip method and other sorting tasks represent alternative approaches to direct questioning through standard qualitative interviewing. In this presentation, the authors will review various ways in which sorting techniques have been employed in ILS research, highlight how these methods are applied in their research (e.g., Edwards, forthcoming), suggest strategies for the inclusion of these tasks in study designs, and describe unique challenges encountered during data collection and analysis.
