Texto completoI en alltmer sammankopplad värld så får epidemiologin en ökad betydelse i folk- och internationell hälsa. Tuberkulos är en av de sjukdomarna som ligger bakom detta. Dess långa inkubationstid och höga dödstal gör att är en av de svåraste bakteriesjukdomarna att få bukt med. Sverige är idag ett låg-endemiskt land men drabbas ändå av ett par hundra fall per år. Majoriteten av dess infekteras i utland och reser sedan in i Sverige. Denna kvalitativa studie har som mål att utvärdera det svenska hälsovårdssystemet utifrån dess organisatoriska struktur. Datainsamlandet har skett via intervjuer med nyckelpersoner inom tuberkulos-vården kring deras uppfattning om den organisatoriska strukturen. Dessa har varit inblandade i att diagnostisera, behandla och smittospåra tuberkulos patienter. Denna data har sedan analyserat utifrån H.Mintzbergs teorier kring organisationsstruktur. Analysen visar att det aktuella systemet har många likheter med modellen Adhocracy, på så sätt att det är en organisation som kan justeras på ett mycket detaljerat och följsamt sätt i en dynamisk kontext. Den kan också producera unika och komplexa produkter i form av skräddarsydda behandlingsplaner och smittspårningar. Systemet lider dock av ett stort behov av inre kommunikation och möter svårigheter när verksamheten utökas. Slutsatsen blir att det nuvarande systemet skulle ha stora utmaningar med att hantera en markant ökning av tuberkulos fall i Stockholm.

Texto completoThis thesis presents a case study of a service delivery system in a telecommunication company and proposes a model for process evaluation and diagnosis. Because service quality is the main factor of its differentiation strategy, the company seeks service improvements by employing satisfaction surveys for identification of its clients´ needs and expectations. Despite its focus on critical factors of success, the company has experienced difficulties in correlating its clients´ perceptions on the service delivered and the internal evaluations aiming cost reduction and process enhancements. This theme brings about numerous issues on the way the enterprises currently manage their service quality in search for continuous, and sustained, improvement as a competitive advantage under the customer´s vision. Given the complexity of the theme, this research concentrates in the particular aspect of customer´s expectations on the service timely delivery, as well as in the management of the order cycle for the company to achieve an efficient, effective and low cost delivery. The main objective of this research is the identification of the gaps between the customer´s perception and the company´s internal view of its performance whose reduction, or elimination, can enhance the market perceived value. Hence, this research proposes and tests a model for diagnosis of the service delivery process, and also, ways for maintaining the alignment of the process with the customer´s expectations, and the organization´s strategy. Focusing on service delivery, this research represents a modest contribution for placing this subject on its deserved place in Logistics.

Texto completoSyftet med denna studie är att undersöka hur nyligen utförda distansexaminationer på KTH har uppfattats av användarna. De rådande omständigheterna i världen som skett till följd av COVID-19 har akut skapat ett stort behov av både undervisning och examination på distans. Genom att utföra kvalitativa intervjuer med både lärare och studenter av olika akademiska bakgrunder kombinerat med datainsamling via enkäter, tidigare studier och statistik har målet varit att undersöka hur distansexaminationerna uppfattats av alla inblandade. Något som framgått till följ av studien är att många inblandade, både studenter och lärare har upplevt en betydlig stress på grund av omställningen som distansexaminationer inneburit. Tydlighet, kommunikation och förberedelse är nyckelord för att utföra distansexaminationer av lyckad karaktär. Utöver att undersöka de metoder som används vid examination på distans har även den ekonomiska aspekten av examinationsformen undersökts. Det framgår tydligt att examination på distans är det bästa alternativet, främst ur ett ekonomiskt perspektiv, men även från ett generellt perspektiv om examinationen utförs på ett säkert och rättvist sätt.

Texto completoThis practice-based research developed from questioning reception of dance and manners of sharing this experience. In venturing countercurrent to a history of dance criticism which bears judgment and makes assessments, I attempted to favor initiatives which disrupt, disturb and blur the borderlines that settle between creativity and reception. The first chapter of this research focuses on the analysis of three choreographic works: Une hypothèse de réinterprétation by Rita Quaglia (2009), histoire(s) by Olga de Soto (2004) and Admiring La Argentina by Kazuo Ohno (1977). Each of these pieces offer three different perceptions of artworks, three ways of speaking about/with artworks, three ways of answering to dance by dancing. The three works analyzed in the first chapter are characterized by the importance they grant to subjectivity as a vector of (perceptive and cognitive) knowledge. Thus, introducing the term “affected critique” to the term “performed reception” implemented the scope of my analysis. This term elects both the subjective dimension within these objects and my personal relationship to the works and people which have moved and “possessed” me over the course of my observations these past years. “Affected criticism” also arises from research on the careers of two dance critics – Laurence Louppe (1938-2012) and Jill Johnston (1929-2010) – which form the core of my second chapter. Through the particularities of their critical practices, I cared to question a heritage from which I wished either to differentiate myself or on the contrary to adopt and develop as my own. This research consequently developed as a progressive mise en abyme of my personal gaze as spectator and of the different ways of working as an artist and researcher. This dissertation therefore tries to embrace and account for the multiple shapes – journal entries, fragments of critical writing, analysis of artworks and artistic practices, performance material – that form as many standpoints from which to observe a body of work. A performative moment will prolong the written work of this research during the submission
Rojas, Castro Dalia Marcela. "The RHIZOME architecture : a hybrid neurobehavioral control architecture for autonomous vision-based indoor robot navigation". Thesis, La Rochelle, 2017. http://www.theses.fr/2017LAROS001/document.
Texto completoThe work described in this dissertation is a contribution to the problem of autonomous indoor vision-based mobile robot navigation, which is still a vast ongoing research topic. It addresses it by trying to conciliate all differences found among the state-of-the-art control architecture paradigms and navigation strategies. Hence, the author proposes the RHIZOME architecture (Robotic Hybrid Indoor-Zone Operational ModulE) : a unique robotic control architecture capable of creating a synergy of different approaches by merging them into a neural system. The interactions of the robot with its environment and the multiple neural connections allow the whole system to adapt to navigation conditions. The RHIZOME architecture preserves all the advantages of behavior-based architectures such as rapid responses to unforeseen problems in dynamic environments while combining it with the a priori knowledge of the world used indeliberative architectures. However, this knowledge is used to only corroborate the dynamic visual perception information and embedded knowledge, instead of directly controlling the actions of the robot as most hybrid architectures do. The information is represented by a sequence of artificial navigation signs leading to the final destination that are expected to be found in the navigation path. Such sequence is provided to the robot either by means of a program command or by enabling it to extract itself the sequence from a floor plan. This latter implies the execution of a floor plan analysis process. Consequently, in order to take the right decision during navigation, the robot processes both set of information, compares them in real time and reacts accordingly. When navigation signs are not present in the navigation environment as expected, the RHIZOME architecture builds new reference places from landmark constellations, which are extracted from these places and learns them. Thus, during navigation, the robot can use this new information to achieve its final destination by overcoming unforeseen situations.The overall architecture has been implemented on the NAO humanoid robot. Real-time experimental results during indoor navigation under both, deterministic and stochastic scenarios show the feasibility and robustness of the proposed unified approach

El método propuesto parte de la conexión entre espacios tonales y descripciones en tiempo y escala temporal. Esta representación conjunta pone de manifiesto la relación entre las jerarquías espaciales y temporales de la tonalidad. Utilizando un modelo simple de inducción tonal, se propone un método de exploración visual del contexto tonal en obras musicales. Dos estudios perceptuales son abordados desde el entorno descriptivo propuesto. En el primer estudio, se pone en evidencia el impacto de la escala temporal como parámetro de un modelo simple de inducción tonal, y se analizan los artificios matemáticos introducidos por evaluaciones en espacios escalados dimensionalmente. En el segundo estudio se propone un modelo de inestabilidad contextual, y se analiza en relación al modelado de la tensión tonal. El método de análisis se generaliza, a través de una categorización contextual en set-classes.

Texto completoPrebiotic beverages made from cashew nut kernels and fruit juice are a viable alternative in the area of new functional productsâ development. Thus, this research aimed to develop three prebiotic beverages made from cashew nut kernels added with fruit juice (grape, mango and pineapple), evaluating how non-sensory attributes (external to the product) and consumersâ characteristics as to behavior and personality affect their acceptance. A factorial 2Â central composite rotatable design was used for the development of the formulations. Focus groups were applied to define the most important label attributes on consumerâs purchasing decision. The illustration, nutritional information and the term prebiotic associated with its functional claim, within their respective levels, were selected for the labelsâ development via the 3x2x3 full factorial design and the employment of conjoint analysis and cluster analysis multi-varying techniques for results evaluation. The mango beverage was evaluated displaying three different label versions in order to check if the expectation generated by different nutritional information affected consumersâ perception as to characteristics of quality, overall impression and purchasing attitude. The beverage added with pineapple juice was compared to its soy-based commercially similar in order to evaluate if information on composition, nutritional characteristics and functional claims associated with these products affect the acceptance and perception of consumers with different behavioral characteristics and personality. The formulations optimized as to acceptance should be added with the following concentrations of sugar and juice, respectively; grape beverage (37% and 7%), pineapple (35% and 7%) and mango (40% and 8%). Among the most important label attributes in the purchasing process, the illustration was the one that mostly influenced, followed by nutritional information and the term prebiotic and its functional claim. The nutritional claims displayed on the label revealed to have a positive impact over the perception of the beverage as to the characteristics of quality, overall impression and purchasing attitude, with information such as â0% lactose, 0% cholesterol and fiber-richâ and â0% lactose, 0% cholesterol and antioxidantsâ found to influence more positively consumers. Information related to the beverages made from soy and cashew nut did not influence the acceptance of flavor nor on the overall impression, nonetheless, it had a positive impact over consumersâ perception as to healthiness and the nutritious value of both, being the cashew nut kernel-based beverage perceived as more nutritious and healthier than the soy-based one. Consumersâ different characteristics as to the interest in healthy eating and food neophobia did not influence the acceptance of the beverages, their perception as healthy food and nutritious value.
Bebida prebiÃticas à base de amÃndoas de castanha de caju e suco de frutas à uma alternativa viÃvel na Ãrea de desenvolvimento de novos produtos funcionais. Assim, este trabalho objetivou desenvolver trÃs bebidas prebiÃticas à base de amÃndoa da castanha de caju adicionadas de suco de frutas (uva, manga e abacaxi), avaliando de que forma atributos nÃo sensoriais (externos ao produto) e caracterÃsticas comportamentais e de personalidade dos consumidores afetam a sua aceitaÃÃo. Utilizou-se um delineamento fatorial 22 do tipo composto central rotacionado para desenvolvimento das formulaÃÃes. Grupos de foco foram empregados para definiÃÃo dos atributos do rÃtulo mais importantes na decisÃo de compra do consumidor. A ilustraÃÃo, as informaÃÃes nutricionais e o termo prebiÃtico associado a sua alegaÃÃo funcional, com seus respectivos nÃveis, foram selecionados para o desenvolvimento dos rÃtulos por meio de delineamento fatorial completo do tipo 3 x 2 x 3, aplicando-se as tÃcnicas multivariadas conjoint analysis e cluster analysis para avaliaÃÃo dos resultados. A bebida de manga foi avaliada associada a trÃs versÃes do rÃtulo para verificar se a expectativa gerada por diferentes informaÃÃes nutricionais afetavam a percepÃÃo dos consumidores quanto Ãs caracterÃsticas de qualidade, impressÃo global e atitude de compra. A bebida adicionada de suco de abacaxi foi comparada frente ao seu similar comercial à base de soja para avaliar se informaÃÃes sobre composiÃÃo, caracterÃsticas nutricionais e alegaÃÃes funcionais associadas a estes produtos afetam a aceitaÃÃo e percepÃÃo dos consumidores com diferentes caracterÃsticas comportamentais e de personalidade. As formulaÃÃes otimizadas quanto à aceitaÃÃo devem ser adicionadas das seguintes concentraÃÃes de suco e aÃÃcar, respectivamente, para a bebida de uva (37% e 7%), abacaxi (35% e 7%) e manga (40% e 8%). Dentre os atributos do rÃtulo mais importantes no processo de compra, a ilustraÃÃo foi o que mais influenciou, seguido pelas informaÃÃes nutricionais e pelo termo prebiÃtico e sua alegaÃÃo funcional. As alegaÃÃes nutricionais no rÃtulo mostraram ter um impacto positivo na percepÃÃo da bebida quanto Ãs caracterÃsticas de qualidade, impressÃo global e atitude de compra, com os as informaÃÃes â0% lactose, 0% colesterol e fonte de fibrasâ e â0% lactose, 0% colesterol e antioxidantesâ influenciando mais positivamente os consumidores As informaÃÃes relacionadas Ãs bebidas de soja e castanha de caju nÃo influenciaram a aceitaÃÃo do sabor e impressÃo global, no entanto tiveram um impacto positivo na percepÃÃo dos consumidores quanto à saudabilidade e o valor nutritivo de ambas, sendo a bebida à base de amÃndoa da castanha de caju percebida como mais nutritiva e mais saudÃvel do que a bebida de soja. As diferentes caracterÃsticas dos consumidores quanto ao interesse em alimentaÃÃo saudÃvel e a neofobia alimentar nÃo tiveram influÃncia sobre a aceitaÃÃo das bebidas, a percepÃÃo de alimento saudÃvel e valor nutritivo.

Texto completoSpatial navigation is a complex function requiring the combination of external and self-motion cues to build a coherent representation of the external world and drive optimal behaviour directed towards a goal. This multimodal integration suggests that a large network of cortical and subcortical structures interacts with the hippocampus, a key structure in navigation. I have studied navigation in mice through this global approach and have focused on one particular type of navigation, which consists in remembering a sequence of turns, named sequence-based navigation or sequential egocentric strategy. This navigation specifically relies on the temporal organization of movements at spatially distinct choice points. We first showed that sequence-based navigation learning required the hippocampus and the dorsomedial striatum. Our aim was to identify the functional network underlying sequence-based navigation using Fos imaging and computational approaches. The functional networks dynamically changed across early and late learning stages. The early stage network was dominated by a highly inter-connected cortico-striatal cluster. The hippocampus was activated alongside structures known to be involved in self-motion processing (cerebellar cortices), in mental representation of space manipulations (retrosplenial, parietal, entorhinal cortices) and in goal-directed path planning (prefrontal-basal ganglia loop). The late stage was characterized by the emergence of correlated activity between the hippocampus, the cerebellum and the cortico-striatal structures. Conjointly, we explored whether path integration, model-based or model-free reinforcement learning algorithms could explain mice’s learning dynamics. Only the model-free system, as long as a retrospective memory component was added to it, was able to reproduce both the group learning dynamics and the individual variability observed in the mice. These results suggest that a unique model-free reinforcement learning algorithm was sufficient to learn sequence-based navigation and that the multiple structures this learning required adapted their functional interactions across learning

The purposes of this study were to understand emergency physicians’ perception, attitude and application of evidence-based medicine(EBM). This cross-sectional study employed quantitative methods. Regarding the quantitative method, the study population included emergency physicians in southern Taiwan of 32 participating hospitals. Structured questionnaires were sent to emergency physicians, a total of 214 questionnaires were distributed with 189 questionnaires being returned. The response rate was 88.32%. Descriptive statistics was used in data analysis. The major findings were: 1. Emergency physician’s perception of EBM: The average score in Physicians’ understanding EBM terminologies were from 1.88 to 2.79(score ranged from 1 to 4, 1 represented fully understand). 2. Emergency physician’s attitude of EBM: a. There were over a half (57.7%) emergency physicians had taken EBM training courses, while 93.1% expressed their willingness to attend EBM activities in the future. b. Most emergency physicians(86.7%) agreed that application of EBM was useful in clinical practice. c. The major barriers of emergency physicians to apply EBM were lack of time(57.1%), lack of EBM knowledge(50.3%), lack of research methodology knowledge(45.5%) and hardness of critical appraisal(40.7%). d. In general, emergency physicians hold positive attitudes toward EBM, the average score was from 1.79 to 3.09 (score ranged from 1 to 5, 1 represented the most agree). 3. Emergency physician’s application of EBM: a. The average proportion of EBM application in emergency physicians’ clinical practice was 54.42% . b. Emergency physician’s choice of clinical problem-treating was diverse, only little clinical problem may have uniform opinions.

A wide variety of events occur on daily basis that triggers the responses, opinions and feelings of the public. Such occurrences usually form part of public news issues which tend to be broadcasted by news media companies through different news forums such as social media, websites, television and others. To investigate the perceptions of the public towards the different news affairs, sentiment analysis is performed on the responses of the public on each news content. Machine learning algorithms are employed to perform the investigations and predictions on the public opinions and perceptions from the different sources of the news issues like Facebook. Social media platforms like Facebook and Twitter are expansively utilized by people and establishments such as news media companies and governments to share information. Facebook is the most used social networking site in the world with more than 2.3 billion active users a month and an average of more than 1.5 billion active users daily as of March 31, 2019. Facebook is one of the social media which allows its members to post status updates on their timelines and comments on other user’s posts. Facebook allows application developers to access public Facebook posts and comments. NETVIZZ is a data collection and extraction tool that enables researchers to export data in standard file formats from different sections of the Facebook social networking service. Sentiment Analysis (SA) is one small application of Natural Language Processing, computational linguistics, and text analytics to find out and extract subjective information from social media. Therefore, in this thesis, Facebook posts and comments are extracted and sentiment analysis is implemented on them. Based on the results of the sentiment analysis, predictions can be drawn to determine the perceptions of the public on the Facebook News posts. Machine learning techniques, Naïve Bayes, Support Vector Machine and Logistic Regression are compared to determine the best classifier which is further employed to do the sentiment analysis of the news comments and determine the general views of the public from the text they post on Facebook.

Background: With the advancements of living standard, the public much more concern the health issues and forces each hospital to set up a self-appraisal monitoring system to increase the quality of healthcare. However past research mainly emphasis on the patients’ satisfaction, few of them noticed about the importance of medical services which patients pay much attention to. Aims: The purposes of this study were to explore the importance and satisfaction of the medical services, finding out the most potential services demanded through the opportunity algorithms analysis. The present study also examines the relationships and find out the determinants of the overall satisfactions, patient loyalty and recommendation. Methods: A cross-sectional survey was conducted and there were 462 outpatients who recruited in a medical center in Northern Taiwan in the study. The present study employed a structured questionnaire which contains of 5 Rating Components (includes Accessibility, Appropriateness, Accessibility, Coordination, Comprehensive and Continuity) which used to measure the importance and satisfaction of the medical service. Data was analyzed using SPSS 14 for Windows. Results: The research demonstrated that the most importance service items were “hospital’s medical equipment is better than community clinic”, “medical profession” and “familiar which medical instrument operates”. Besides, patient most satisfaction with “medical equipment is better than community clinic”, “initiates the non-tobacco environment” and “keep the medical record properly”. Yet, "physician utilization", "condition of continuing care" and "service route planning or direction is clear" were the services with most in need for further improvement. The study also revealed the relationships between the overall satisfactions, patient loyalty and recommend voluntarily were remarkable. Through the analysis of regression, factors of “doctor will suggest the patient transfers to the other disciplines” or “hospital regards patient’s need”, “discuss with the patient after seeing a different doctor”, “even inform before carrying any treatment and so on behaviors” were proving to increase the patient loyalty. Present study also showed the level of patients’ satisfaction on “overall registration mode”, “doctor-patient communication”, “the burden of medical expenses” and the “solution when registration number was passed” were most able to predict the overall satisfaction of the medical center. To improve patient satisfaction, concise service route directions, professional training which emphasize on time concept and continuity care should be priorities. Conclusions: The study concludes that while the gap of the medical service were truly filling up, there may help to promote the hospital’s performance as well as the quality of the medical service.

Currently, thanks for the development of video technology, the major topic of TV change from 2D to 3D. Compare to the traditional 2D video contents and 3D video contents, that need view content for 2D video and at least two or more than views for 3D video, respectively. Huge information of 3D video contents causes the awkward situation during data compression and data transmission. To solve the problem, Joint Video Team (JVT) proposes a coding method that utilizes the content-similar relationship between neighboring views to increase the efficiency of multi-view video coding (MVC). Therefore, rate control (RC) algorithm is the key technique to tradeoff data compression ratio and video quality of 3D video. To control the bit-rate efficiently, considering video quality and compression ratio, the proposed algorithm utilizes the characteristic of visual perception theory from the analysis of 3D video that the region with high motion and individual object feature are interesting to viewer. Based on the concept, the proposed rate control algorithm gives the high bit-rate at the interesting region for preserve the image quality, decreases the image quality at the region of non-interesting for saving the bit-rate. The proposed algorithm determines interesting region with high motion feature by using the relationship between luminance difference and Just Noticeable Distortion (JND) function at the current and reference macro-block (MB). To enhance the ability of describing motion feature, the proposed algorithm uses luminance histogram bin variation of the two MBs to describe low motion feature, edge strength (ES) describes the object with individual shape and obvious texture. By the interesting region determination, the rate-control algorithm is used by quantization parameter (QP) defining to control bit-rate at different levels of interesting region.

The rate of occupational accident of Taiwan industry is higher than the advanced country such as America, England, and Japan etc. To reduce the occurrence of occupational accident, the authority has established varieties of policies of labor''s safety and health, and demand the employer and employee to obey. The corporations set up their own policies of labor''s safety and health according to the nature and hazards of their corporations. And these policies will be the core conception and the goal for the management of labor''s safety and health. But if laborers do not perceive and obey the policies, the rate of occupational accident will not reduce effectively. So we must study the perception and compliance of labor for the policies of labor''s safety and health. The main reason for the occupational accident is the unsafe behaviors of laborer, and the perception (knowledge and attitude) of safety and health will influence the occurrence of unsafe behaviors. So it is helpful to study the labor''s perception of safety and health, for the authority and corporations to set up the policies to prevent the occupational accident effectively. The object of this research is to investigate the perception of safety and health and the policies of safety and health of the employees of Chung-Hwa Telecom Co., and analyze the tendency and deviation. By the method of interviewing and questionnaires designed by the author, the empirical evidences show that: 1.The employees of Chung-Hwa Telecom Co. identify that the first reason for the occupational accident is the negligence of laborer, the second is the problem of the environment of working, and the third is the facilities of protection. 2.In the employees of Chung-Hwa Telecom Co., the more compliant to the policy of safety and health, the more important they think of safety and health. And the motivation, the self-control belief, the training and education, the compliance are positive relevant. They think that the policy of safety and health of the corporation can reduce the occurrence of occupational accident; to the perception of safety and health, the older male employees got the better perception. 3.In the employees of Chung-Hwa Telecom Co., to the self-control belief that occupational accident can be prevented by being careful. 4.In the employees of Chung-Hwa Telecom Co., to the acceptance of training and education of safety and health, the employees whose tenure is more than 30 years are better than those whose tenure is less than 10 years. 5.In the employees of Chung-Hwa Telecom Co., to the whole perception of safety and health, (1) the male employees are better than the female employees. (2) the employees of technical department better than the employees of business department. (3) the older are better than the younger. (4) the employees whose tenure is more than 30 years are better than those whose tenure is less than 10 years.

Texto completoBrand reputation has received the attention of many scholars and practitioners because it is central to the success of organisations of all kinds, and an intangible asset with no substitute. In the academic world, brand reputation has been demarcated by various scholars, depending on the disciplinary mind-set involved. It has been established that diverse stakeholder groups have different needs from a brand and their perceptions of brand reputation are thus varied. Acknowledging the needs of different stakeholders and the importance of the consumer stakeholder group allows for a more nuanced and systematic approach in conceptualising brand reputation. Although numerous studies have attempted to explain brand reputation, there is a paucity of studies that have actually conceptualised brand reputation as an attitudinal construct based on both cognitive (rational) and affective (emotional) components. Even fewer researchers have endeavoured to conceptualise brand reputation as an attitudinal construct in the consumer stakeholder group. The aim of this study was to explore female consumer perceptions of Nike’s brand reputation and conceptualise brand reputation as an attitudinal construct based on both cognitive and affective components. The study used qualitative research methods (focus groups and interviews) to collect data on Nike from a group of female consumers in order to identify perceptions and elements that contribute to conceptualising brand reputation on the basis of the components of attitudes. The key findings of this study highlighted the fact that brand reputation is a multidimensional construct and can be demarcated through various elements that contribute to the following themes: perception of product qualities and service, the perception of brand traits and the perception of brand strategy. These themes contribute to the conceptualisation of brand reputation as an attitudinal construct. Since brand reputation as an attitudinal construct has previously been conceptualised based on cognitive and affective components, this study confirmed the two components but a unique finding of this study was the identification of the behavioural component of attitudes. Hence the study findings not only make a contribution to the existing body of knowledge on perceptions of brand reputation in an elusive stakeholder group – female consumers, consumer-based reputation (CBR), and in defining brand reputation but also conceptualise brand reputation as an attitudinal construct based on previously identified cognitive and affective components as well as the newfound behavioural component of attitudes.

Buscar texto completoCourse-based Undergraduate Research Experiences (CUREs) have been described in a range of educational contexts. Although various learning objectives, termed anticipated learning outcomes (ALOs) in this project, have been proposed, processes for identifying them may not be rigorous or well-documented, which can lead to inappropriate assessment and speculation about what students actually learn from CUREs. Additionally, evaluation of CUREs has primarily relied on student and instructor perception data rather than more reliable measures of learning.This dissertation investigated a novel biochemistry laboratory curriculum for a Course-based Undergraduate Research Experience (CURE) known as the Biochemistry Authentic Scientific Inquiry Lab (BASIL). Students participating in this CURE use a combination of computational and biochemical wet-lab techniques to elucidate the function of proteins of known structure but unknown function. The goal of the project was to evaluate the efficacy of the BASIL CURE curriculum for developing students’ research abilities across implementations. Towards achieving this goal, we addressed the following four research questions (RQs): RQ1) How can ALOs be rigorously identified for the BASIL CURE; RQ2) How can the identified ALOs be used to develop a matrix that characterizes the BASIL CURE; RQ3) What are students’ perceptions of their knowledge, confidence and competence regarding their abilities to perform the top-rated ALOs for this CURE; RQ4) What are appropriate assessments for student achievement of the identified ALOs and what is the nature of student learning, and related difficulties, developed by students during the BASIL CURE? To address these RQs, this project focused on the development and use of qualitative and quantitative methods guided by constructivism and situated cognition theoretical frameworks. Data was collected using a range of instruments including, content analysis, Qualtrics surveys, open-ended questions and interviews, in order to identify ALOs and to determine student learning for the BASIL CURE. Analysis of the qualitative data was through inductive coding guided by the concept-reasoning-mode (CRM) model and the assessment triangle, while analysis of quantitative data was done by using standard statistical techniques (e.g. conducting a parried t-test and effect size). The results led to the development of a novel method for identifying ALOs, namely a process for identifying course-based undergraduate research abilities (PICURA; RQ1; Irby, Pelaez, & Anderson 2018b). Application of PICURA to the BASIL CURE resulted in the identification and rating by instructors of a wide range of ALOs, termed course-based undergraduate research abilities (CURAs), which were formulated into a matrix (RQs 2; Irby, Pelaez, & Anderson, 2018a,). The matrix was, in turn, used to characterize the BASIL CURE and to inform the design of student assessments aimed at evaluating student development of the identified CURAs (RQs 4; Irby, Pelaez, & Anderson, 2018a). Preliminary findings from implementation of the open-ended assessments in a small case study of students, revealed a range of student competencies for selected top-rated CURAs as well as evidence for student difficulties (RQ4). In this way we were able to confirm that students are developing some of the ALOs as actual learning outcomes which we term VLOs or verified learning outcomes. In addition, a participant perception indicator (PPI) survey was used to gauge students’ perceptions of their gains in knowledge, experience, and confidence during the BASIL CURE and, therefore, to inform which CURAs should be specifically targeted for assessment in specific BASIL implementations (RQ3;). These results indicate that, across implementations of the CURE, students perceived significant gains with large effect sizes in their knowledge, experience, and confidence for items on the PPI survey (RQ3;). In our view, the results of this dissertation will make important contributions to the CURE literature, as well as to the biochemistry education and assessment literature in general. More specifically, it will significantly improve understanding of the nature of student learning from CUREs and how to identify ALOs and design assessments that reveal what students actually learn from such CUREs - an area where there has been a dearth of available knowledge in the past. The outcomes of this dissertation could also help instructors and administrators identify and align assessments with the actual features of a CURE (or courses in general), use the identified CURAs to ensure the material fits departmental or university needs, and evaluate the benefits of students participating in these innovative curricula. Future research will focus on expanding the development and validation of assessments so that practitioners can better evaluate the efficacy of their CUREs for developing the research competencies of their undergraduate students and continue to render improvements to their curricula.

Texto completoMultiresolution image fusion is an emerging area of research for use in military and commercial applications. While many methods for image fusion have been developed, improvements can still be made. In many cases, image fusion methods are tailored to specific applications and are limited as a result. In order to make improvements to general image fusion, novel methods have been developed based on the wavelet transform and empirical variance. One particular novelty is the use of directional filtering in conjunction with wavelet transforms. Instead of treating the vertical, horizontal, and diagonal sub-bands of a wavelet transform the same, each sub-band is handled independently by applying custom filter windows. Results of the new methods exhibit better performance across a wide range of images highlighting different situations.

Texto completoA massive amount of videos are uploaded on video websites, smooth video browsing, editing, retrieval, and summarization are demanded. Most of the videos employ several types of camera operations for expanding field of view, emphasizing events, and expressing cinematic effect. To digest heterogeneous videos in video websites and databases, video clips are profiled to 2D image scroll containing both spatial and temporal information for video preview. The video profile is visually continuous, compact, scalable, and indexing to each frame. This work analyzes the camera kinematics including zoom, translation, and rotation, and categorize camera actions as their combinations. An automatic video summarization framework is proposed and developed. After conventional video clip segmentation and video segmentation for smooth camera operations, the global flow field under all camera actions has been investigated for profiling various types of video. A new algorithm has been designed to extract the major flow direction and convergence factor using condensed images. Then this work proposes a uniform scheme to segment video clips and sections, sample video volume across the major flow, compute flow convergence factor, in order to obtain an intrinsic scene space less influenced by the camera ego-motion. The motion blur technique has also been used to render dynamic targets in the profile. The resulting profile of video can be displayed in a video track to guide the access to video frames, help video editing, and facilitate the applications such as surveillance, visual archiving of environment, video retrieval, and online video preview.

Texto completoMadeline Heilman’s (1983) Lack of Fit Model, which postulates why discrimination occurs in the selection of sex-typed jobs, has been applied to the interaction of applicant attractiveness. Yet recent research suggests that other appearance variables, namely sex-typed facial features, may be associated with perceptions of fit. Building upon Heilman’s 1983 model, the current study evaluated how sex-typed facial features relate to applicant selection for sex-typed fields. Undergraduate students were recruited for participation during the spring academic semester (n = 413) and data were analyzed using a 2x2x2 ANOVA. Results indicated that selection is significantly impacted by the three-way interaction of applicant sex, facial feature-type, and sex type of the applying field. Further, masculine-featured females and feminine-featured males were significantly less favored for selection within the feminine sex-typed field. Implications of these findings and the differential evaluation of male and female applicants in a feminine field are discussed.
