Full textAbstract:
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, NevadaWith the development of microcomputer technology, the application of strap-down inertial navigation on aircraft is used more frequently. The attitude measurement for miniature spacecraft is most important. Installing three-axis acceleration sensors and three-axis rate gyros on the spacecraft, the accelerations and attitudes can be obtained through the PCM/FM telemetry system. Then, the initial attitude of spacecraft is given through outside measurement and telemetry. Finally, in the ground station, the parameters of spacecraft attitude are given by using strapdown inertial navigation theory and quanternion differential equation for solving the attitude.

Full textAbstract:
Research shows that a considerable number of children and adolescents suffer
needlessly from psychological problems and only about 50% of those receive the
necessary services. Considering the impact of untreated child psychological problems on
problems in adulthood, it is important to examine the influence of attitudes on seeking
mental health service for children. Currently, no known measure exists to measure
attitudes toward mental health services for children. Building on previous research, the
goal of the present study was to develop a measure of individuals' attitudes toward
mental health services for children. Using confirmatory factor analysis, the factor
structure was assessed using a sample of university students (N = 250). In addition,
several hypotheses were tested examining the influence of previous experience with
mental health services on attitudes towards psychological services and mental health
stigma. Finally, differences in child characteristics on intended help-seeking were
examined. The measure developed consists of 26-items scored from 0 (strongly
disagree) to 5 (strongly agree). Overall, results indicated that the 3-factor structure of the
measure developed was valid and reliable. Also, consistent with previous research on mental health services results supported the hypotheses of the current study. Future
research will examine whether the 3-factor structure is replicated using a sample of
parents.

Full textAbstract:
Doctor of Philosophy (PhD)In the last two decades, ambivalence has emerged as one of the primary concerns of attitude researchers. The acknowledgement that individuals can simultaneously evaluate an attitude object as both positive and negative has challenged a number of the status quos of the attitude literature. This thesis utilises an unfolding approach to investigate the implications of ambivalence for the conceptualisation of attitudes and their measurement. Firstly, the assumption that ambivalence is at odds with the bipolar understanding of attitudes was investigated. The results suggested that ambivalence is consistent with bipolarity, whereby ambivalent attitudes are located at the centre of the bipolar dimension. Secondly, attitude scales for the abortion, euthanasia and Aboriginal Australians issues were constructed to reflect this bipolar understanding. The fit of these statements to Coombs’ (1964) unidimensional unfolding theory provided evidence that ambivalence is also consistent with the quantitative conceptualisation of attitudes. Together these results provided further validation of the unfolding approach to attitude measurement. These models alleviate many of the problems faced by the ubiquitous method of summated ratings, including the assessment of ambivalent evaluations. Finally, these scales were used to investigate the latent structure of attitudes and its relationship with meta-psychological judgements of ambivalence. The conclusions drawn from these analyses were limited by a number of issues, highlighting the importance of rigorously considering measurement issues for all attitude parameters. Nonetheless, they presented preliminary validation of these scales’ ability to measure ambivalent evaluations and suggested a systematic relationship between proximity to the centre of the evaluative dimension and metapsychological ambivalence. Overall, it is concluded that a number of assumptions regarding the implications of ambivalence are misplaced and the proposed solutions are even more troublesome. Suggestions for future research are made, particularly with respect to differentiating between ambivalent, indifferent and uncertain evaluative states. Furthermore, attitude researchers are encouraged to discard their operationalist biases in order to engage with the measurement issues illuminated throughout this thesis. This is necessary to account for the complexity of the attitude construct, which ambivalence is testament to.

Full textAbstract:
This research aims to investigate the nature of high β-angle cornering as
seen in rallying and in particular the World Rally Championship. This is
achieved through a combination of sensor development, on-car measurement
and vehicle dynamic simulation.
Through the development of novel β-angle measurement technology it has
become possible to measure and study vehicle attitude dynamics on loose
gravel surfaces. Using this sensor, an understanding of how a rally driver
uses the dynamics of the vehicle and surface to maximise performance has
been obtained.
By combining the new data stream with accepted vehicle dynamic theory,
the tyres have been considered and general trends in gravel tyre performance
unveiled. Through feedback, these trends have been implemented as a means
of tuning a dynamic model to improve realism and permit an analysis of
cornering trends in rally cars.
Active control systems have been considered that could implement more
sophisticated algorithms based on this understanding and potentially use the
new sensor information as an input signal. A case study which explores such
a possibility is included.

Full textAbstract:
A non-contact angular measurement system for Pitch Static Attitude (PSA) and Roll Static Attitude (RSA) of hard disk drive sliders is designed and built. Real-time sampling at over 15 KHz is achieved with accuracy of +/- 0.05 degrees over a range of approximately 2-3 degrees. Measuring the PSA and RSA is critical for hard drive manufacturers to control and improve the quality and reliability of hard drives. Although the hard drive industry is able to measure the PSA and RSA at the subassembly level at this time, there is no system available that is able to measure PSA/RSA at the final assembly level. This project has successfully demonstrated a methodology that the PSA/RSA can be reliably measured in-situ using a laser and position sensitive detector (PSD) technology. A prototype of the measurement system has been built using simple and inexpensive equipment. This device will allow a continuous measurement between the parked position on the ramp and the loading position just off of the disk surface. The measured data can be used to verify manufacturing processes and reliability data.

Full textAbstract:
This paper describes, the development of a sensor fusion algorithm-based Kalman lter ar- chitecture, in combination with a low cost Inertial Measurement Unit (IMU) for an Attitude Heading Reference System (AHRS). A low cost IMU takes advantage of the use of MEMS technology enabling cheap, compact, low grade sensors. The use of low cost IMUs is primar- ily targeted towards Unmanned Aerial Vehicle (UAV) applications due to the requirements for small package size, light weight, and low energy consumption. The high dynamics nature of smaller airframes, coupled with the typical vibration induced noise of UAVs require an e cient, reliable, and robust AHRS for vehicle control. To eliminate the singularities at 90 on the pitch and roll axes, and to keep the computational e ciency high, quaternions are used for state attitude representation.

Full textAbstract:
Researchers interested in measuring people's underlying attitudes towards an object (e.g., abortion) often collect Likert data by administering a survey. Likert data consist of surveyees' responses to statements about the object, where responses fall into ordered categories running from `Strongly agree' to `Strongly disagree' or into a `Don't Know / Can't Choose' category. Two examples of Likert data are used for illustrative purposes. The first dataset was collected by the author from American and British graduate students at Oxford University and contains items measuring underlying abortion attitudes. The second dataset was taken from British and American responses to the 1995 National Identity Survey (NIS) and contains items measuring underlying national pride and immigration attitudes. A model for Likert data and underlying attitudes is introduced. This model is more principled than existing models. It treats people's underlying attitudes as latent variables, and it specifies a relationship between underlying attitudes and responses that is consistent with attitudinal research. Further, the formal probability model for responses allows people's interpretation of the response categories to differ. The model is fitted by maximising an appropriate likelihood. Variants of the model are used to analyse Likert data in three contexts; in each, the method using our model compares favourably to existing methods. First, the model is used to visualise the structure underlying the abortion attitude data. This method of visualization produces more sensible plots than analogous multivariate data visualization methods. Second, the model is used to select the statements whose responses (in the abortion attitude data) best reflect underlying abortion attitudes. Our method of statement selection more closely adheres to attitude researchers' stated aims than popular methods based on sample correlations. Third, the model is used to investigate how underlying national pride varies with nationality in the NIS data and also how underlying abortion attitude varies with gender, religious status, and nationality in the abortion attitude data. Unlike methods currently used by social scientists to model the relationship between attitudes and covariates, our method controls for the effects of differing response category interpretation. As a result, inferences about group differences in underlying attitudes are more robust to group differences in response category interpretation.

Full textAbstract:
The concept of CSR is increasingly important in society, and firms are expected to be profitable while ethical. Deciding how to best engage in CSR activities can be difficult, but using a supply-and-demand framework can help firms to maximize their CSR activities. However, the demand for CSR has been proven difficult to measure, but can perhaps be established when dividing the demand into different components. The purpose of this study is therefore to investigate how consumer awareness, attitude, and buying behavior, in relation to CSR, affect each other; to establish a measurement for consumer demand for CSR. To find an answer, an explanatory and a deductive research approach was used and consumers were surveyed in a quantitative study to establish a measurement for the consumer demand for CSR. This study provides both managerial and theoretical implications to the field of CSR. The theoretical implication lies in contributing empirical evidence into the discussion of supply-and-demand for CSR. Practically, this study informs managers, in the fast fashion industry, that consumer attitude can be used as a measurement when establishing the consumer demand for CSR. It is suggested for future research that it would be interesting to use other control variables to further elaborate on the findings of this study.

Full textAbstract:
Students' retention in STEM-related careers is of great concern for educators and researchers, especially the retention of underrepresented groups such as females, Hispanics, and Blacks in these careers. Therefore it is important to study factors that could potentially influence students' decision to stay in STEM. The work described in this dissertation involved three research studies where assessments have been used in college chemistry courses to assess students' prior content knowledge, chemistry-self-efficacy, and attitude toward science. These three factors have been suggested to have an influence on students' performance in a course and could eventually be a retention factor.
The first research study involved the development and use of an instrument to measure biochemistry prior knowledge of foundational concepts from chemistry and biology that are considered important for biochemistry learning. This instrument was developed with a parallel structure where three items were used to measure a concept and common incorrect ideas were used as distractors. The specific structure of this instrument allows the identification of common incorrect ideas that students have when entering biochemistry and that can hinder students' learning of biochemistry concepts. This instrument was given as pre/posttest to students enrolled in introductory biochemistry courses. The findings indicated that some incorrect ideas are persistent even after instruction, as is the case for bond energy and the structure of the alpha helix concepts. This study highlights the importance of measuring prior conceptual knowledge; so that instructors can plan interventions to help students overcome their incorrect ideas.
For the second research study, students' chemistry self-efficacy was measured five times during a semester of preparatory college chemistry. Chemistry self-efficacy beliefs have been linked to students' achievement, and students with stronger self-efficacy are more likely to try challenging tasks and persist in them, which will help them to stay in STEM. Using multilevel modeling analysis to examine potential differences in students' self-efficacy beliefs by sex and race/ethnicity, it was found that there were some differences in the trends by race/ethnicity. In particular, we found that for Hispanic and Black males the trends were negative when compared with White males. This study highlights the importance of measuring self-efficacy at different time points in the semester and for instructors to be aware of potential differences in their students' confidence when working on a chemistry task.
The third research study involves the use of the Test of Science Related Attitudes (TOSRA) in an introductory chemistry course. A shortened version of the instrument that includes three scales, normality of scientists, attitude toward inquiry, and career interest in science was used. The first purpose of this study was to gather validity evidence for the internal structure of the instrument with college chemistry students. Using measurement invariance analysis by sex and race/ethnicity, it was found that the internal structure holds by sex, but it did not hold for Blacks in our sample. Further analysis revealed problems with the normality scales for Blacks. The second purpose was to examine the relationship between the scales of TOSRA, achievement in chemistry, and math prior knowledge. Using Structural Equation Modeling (SEM) it was found that two of the TOSRA scales, attitude toward inquiry and career interest in science, have a small but significant influence on students' achievement in chemistry. This study highlights the importance of examining if the scores apply similarly for different group of students in a population, since the scores on these assessments could be used to make decisions that will affect student.
The research studies presented in this work are a step forward with our intention to understand better the factors that can influence students' decisions to stay or leave STEM-related careers. Each study has provided psychometric evidence for the use of three different assessments in college chemistry courses. Instructors can use these assessments in large and small lecture classrooms. Information obtained from these assessments can then be used to make target interventions to help students learn and/or be more confident on a given task. Also, it highlights the importance to look at different group of students, such as the underrepresented groups, since response trends may be different. Being aware of students' diverse needs will help us to understand some of the challenges that student face in the chemistry classroom. Understanding some of these challenges will help instructors be more prepared for teaching.

Full textAbstract:
The study utilized the covariance structure comparison methodology - Multigroup Analysis in Structural Equation Modeling - evaluating measurement equivalence of English and Spanish versions of an employee opinion survey. The concept of measurement equivalence was defined as consisting of four components: sample equivalence, semantic equivalence, conceptual equivalence and scalar equivalence. The results revealed that the two language versions of the survey exhibited acceptable measurement equivalence across five survey dimensions Communications, Supervision, Leadership, Job Content & Satisfaction and Company Image & Commitment. Contrary to the study second hypothesis, there was no meaningful difference in opinion scores between English-speaking and Spanish-speaking respondents on the latent construct of Job Content & Satisfaction.

Full textAbstract:
L'hypertension artérielle (HTA) est un problème de santé sérieux qui affecte 22% des canadiens et dont les complications sont nombreuses. Ces complications peuvent être diminuées par un diagnostic précoce et un traitement efficace et plusieurs auteurs affirment que l'exactitude de la mesure de la pression artérielle (PA) est la pierre angulaire pour établir le diagnostic et assurer un suivi adéquat. Quoique cette mesure soit réalisée très fréquemment, des études réalisées ailleurs qu'au Québec indiquent que les connaissances des infirmières à l'égard de la mesure de la PA sont insuffisantes pour des éléments reconnus comme ayant une influence significative sur les résultats de la mesure de la PA. À notre connaissance, aucune étude concernant les connaissances des infirmières n'a été publiée au Canada. Cette étude a donc pour but de décrire les connaissances théoriques et pratiques des infirmières pour la mesure de la PA en regard des recommandations du Programme éducatif canadien pour le contrôle de l'hypertension artérielle (2004) et comparer les relations entre ces variables. Une enquête par questionnaire auto administré pour décrire les connaissances théoriques ainsi qu'une observation directe par échantillonnage exhaustif pour décrire les connaissances pratiques ont été utilisées pour un premier échantillon de 50 infirmières. Une enquête postale transversale par échantillonnage aléatoire a été utilisée pour décrire les connaissances théoriques auprès d'un deuxième échantillon de 307 infirmières. Les outils ont été testés pour leur validité et leur fidélité dans le cadre de cette étude. L'étude a été approuvée par le comité d'éthique du centre de recherche clinique du CHUS. Les résultats quant aux données sociodémographiques démontrent que les infirmières ayant participé à l'une ou l'autre partie de l'étude sont semblables aux autres infirmières du Québec à l'égard du genre, de l'âge, du type d'emploi et de l'expérience. Elles sont toutefois statistiquement différentes pour le niveau de formation. Le score obtenu par les infirmières des deux échantillons pour le questionnaire sur les connaissances théoriques est de moins de 60%. On peut donc conclure qu'il existe des lacunes importantes en regard des connaissances théoriques acquises. Par ailleurs, ces infirmières croient dans de très fortes proportions posséder les connaissances théoriques et pratiques nécessaires à une mesure exacte de la PA. Pour les connaissances pratiques, le score global des infirmières est de 38%. Force est de croire que malgré le processus de mise à jour annuel et d'implantation des recommandations canadiennes, les connaissances pratiques des infirmières ne sont pas équivalentes au contenu de ces recommandations. Les infirmières qui détiennent un niveau de formation supérieur, celles qui ont lu les recommandations et celles qui ont suivi une formation continue sur la mesure de la PA obtiennent de résultats légèrement supérieurs aux autres infirmières. Considérant la fréquence avec laquelle les infirmières mesurent la PA et l'impact que peut avoir une mesure inexacte, il est important d'entreprendre dès maintenant des actions concrètes pour améliorer cette situation en mettant en place des formations continues régulières sur le sujet et en s'assurant que les programmes de formation initiale incluent une formation théorique et pratique fondée sur les recommandations en vigueur. Il semble également crucial de stimuler l'implantation des recommandations du PECH auprès des infirmières et d'évaluer l'impact de ces mesures par la suite.

Full textAbstract:
Since the dawn of the space race, satellites have grown rapidly in complexity and shrunk equally rapidly in size. Most of them contain an Attitude Determination and Control System (ADCS) on board for pointing and detumbling manoeuvres. These intricate systems are designed for an outer space environment, hence, phenomenon otherwise abscent in space, such as gravity and aerodynamic drag present a challenge in validating these systems on Earth. The gimbal suspension testbed aims to provide a 3 Degree of Freedom (DoF) suspension where the mounted satellite under test can rotate about either axis. The suspension induces disturbance torques that must be modeled in order for the testbed to be characterized. This is accomplished by formulating the necessary gimbal dynamics, bearing friction, aerodynamic and Center of Mass (CoM) displacement torque model. This yields a relationship from which all torques present in the system can be expressed in terms of the angles, angular velocities and angular accelerations of the gimbal frames. By measuring the angles and obtaining the velocities and accelerations through numerical differentiation, the torques that correspond to a certain motion can be calculated. Furthermore, the thesis covers the iterative design of the gimbal suspension and all of its constituents, the angular measurement method and a Finite Element Method (FEM) simulation to estimate deformations. The result is presented in terms of a simulation that validates the models by predicting its behaviour for certain movement. The final result is a series of characterization plots that tells the user of the gimbal testbed how much torque must be produced by the CubeSat ADCS in order to operate it.Sedan begynnelsen av rymdkapplöpningen har satelliter snabbt ökat i komplexitet och lika snabbt minskat i storlek. De flesta satelliter har ett attitydsbestänings- och kontrollsystem (ADCS) ombord för att kunna utföra vissa manövrar. Dessa system är designade för rymdmiljön, därför kan fenomen som annars är frånvarande i rymden, så som gravitation och luftmotstånd, innebära en utmaning då man önskar att validera systemet på jorden. Gimbalupphängningen förmedlar rotation med tre frihetsgrader där satelliten under test kan rotera kring alla tre axlar. Upphängningen inducerar störmoment som måste modelleras för att den ska bli ordentligt karaktäriserad. Detta åstadkoms genom att formulera gimbalens dynamiska förhållanden, kullagerfriktion, luftmotstånd och masscenterförflyttning. Dessa samband kopplar samman alla moment som är närvarande i systemet som funktion av gimbalramarnas vinklar, vinkelhastigheter och vinkelaccelerationer. Genom att mäta vinklarna och erhålla vinkelhastigheter och vinkelacceleration genom numerisk derivering kan momenten som motsvarar den uppmätta rörelsen beräknas. Dessutom presenteras den iterativa designen av gimbalupphängningen och alla dess beståndsdelar, vinkelmätningsmetoden och en finita elementmetodssimulering för att uppskaffa deformationer. Resultatet presenteras i form av simuleringar som validerar modellen genom att förutspå dess beteende för viss rörelse. Det slutgiltiga resultatet är en serie av karaktäriseringsgrafer som förmedlar till användaren just hur mycket moment dess CubeSats ADCS måste producera för att kunna använda gimbalupphängingen.

Full textAbstract:
Problem Faith in the power of advertising has varied largely through the ages, and since we know that advertising is paid for, it therefore has less weight than the usual news. Publicity through promotional activities is in turn difficult to control. The question which of these two ways to communicate with the market that is the most effective, is equally entitled to ask, as difficult to answer.
Purpose/Aim This paper is designed as a pilot study with two different objectives that go hand in hand. The first overall aim is to investigate how advertising and PR / publicity can be measured with the same tools while designing this metric. The second aim is to test whether this metric can find any differences in the advertisements or publicity efficiency.
Method The main study that the paper leads to is an experiment that examines how two different groups is affected by the promotional and advertising materials. The two groups have been allocated an identical magazine with a difference between the groups. One group magazine was prepared by a published material as a possible result of a PR activity, such as a loan product or a press release. The second group magazine was prepared with an ad. In order to assure that good reliability achieved in the survey, two preparatory studies were carried out. The entire study leans towards a theoretical framework.
Main results The conclusions of the paper are that this approach can seem to find differences between PR and paid advertising. However, the difference is small and focuses on increased probability of purchase after exposure of the ad. PR-material had a weaker effect than the advertisement in this case. The essay will give a basis for further research based on the experimental design used in the study.

Knowledge of how gender affects learning is scarcely understood in the realm of nursing education. Prior studies have indicated certain learning styles are predictors of passing board examinations. Pinpointing specific learning styles could improve educational outcomes and produce thoroughly equipped nurses. Previous researchers have studied the differences in learning preferences according to gender; however, no studies have solely concentrated on gender specific learning preferences among undergraduate nursing students. Learning Interest, as well as Goal Orientation, were found to be statistically significant between genders.

Bakgrund: Studier visar att sjuksköterskor ofta underskattar barns smärta. Vid omvårdnad av barn med smärta bör självskattning vara förstahandsvalet vid smärtskattning. Smärtskattning och dokumentation är sjuksköterskans ansvar, därför behöver sjuksköterskor utbildning och riktlinjer för att förbättra smärtbehandlingen för barn och ungdomar. Syfte: Syftet var att kartlägga sjuksköterskors attityder och kunskaper gällande smärta hos barn och ungdomar på en pediatrisk akutvårdsavdelning. Ytterligare ett syfte var att se om en intervention kan påverka sjuksköterskornas attityder och kunskaper samt smärtskattningsfrekvens. Metod/design: En kvantitativ kvasiexperimentell studie utfördes. En enkät besvarades av 30 sjuksköterskor före och efter en intervention, vilken innebar ett deltagande i en utbildning om barns smärta och användning av smärtskattningsinstrument. Vid utbildningen utformades även riktlinjer gällande smärtskattning på avdelningen. Resultat: När användandet av smärtskattning värderades i en femgradig betygsskala fick sjuksköterskorna högre medelbetyg efter interventionen jämfört med innan (1,69 vs 2,5; p=0,049). Ingen signifikant förändring kunde påvisas gällande sjuksköterskornas attityder och kunskaper. Slutsats: Smärtskattningsfrekvensen blev signifikant högre efter en intervention med evidensbaserat utbildningsmaterial och utformning av riktlinjer för smärtskattning. Ingen skillnad hittades mellan bakgrundsfaktorer och attityd- och kunskapsformuläret. Sjuksköterskorna på avdelningen behöver fortsätta arbeta för att riktlinjerna kring smärtskattning följs och uppdateras utifrån forskning och kliniska erfarenheter.Background: Studies show that nurses often underestimate children´s pain. Self-report should be the standard when caring for a child with pain. Pain measurement and documentation is the nurse´s responsibility, therefore pediatric nurses need education and established guidelines to improve pediatric pain management. Aim: The aim was to survey nurse`s knowledge and attitudes regarding pain in children and adolescents in an pediatric ward. Another aim was to investigate if an intervention could affect nurse’s knowledge and attitudes towards children`s pain, as well as the frequency of pain measurement. Method: A quantitative and quasi-experimental study was conducted. A questionnaire was handed out to 30 nurses before and after an intervention regarding pain in children. During the intervention the nurses learned how to use validated pain measurement-tools and guidelines regarding pain measurement was formed. Results: The use of pain measurement-tools were evaluated in a five-point rating scale, the nurses got higher average points after the intervention than before (1.69 vs 2.5; p=0,049). No significant change was found regarding nurses' attitudes and knowledge. Conclusion: The frequency of pain measurement was significantly higher after an intervention with evidence based training and development of guidelines for pain measurement. No difference was found between background information and the answers to the questionnaire. Nurses on the ward have to continue the evaluation of pain measurement and the guidelines based on research and experiences.

Full textAbstract:
Många personer över 65 år lever med smärta. Det ingår i sjuksköterskans arbetsuppgifter att bedöma och utvärdera smärta. Syfte: Syftet med denna litteraturstudie var att genom existerande forskning beskriva vårdpersonals kunskap och attityder till smärtbedömning och smärtskattning i sitt dagliga arbete vid vård av äldre. Metod: I denna litteraturstudie användes sökbaserna Cinahl och Pubmed. Resultat: Resultatet baseras på 10 artiklar, 7 kvantitativa , 2 kvalitativa och en artikel där båda metoderna användes. De faktorer som påverkar smärtskattningen sågs vara erfarenhet och utbildning, utbildning i smärtskattning visade sig öka självförtroendet hos personalen. Även olika hinder, så som kognitiv nedsättning hos patienten och tidsbrist för vårdpersonalen, ligger i vägen för en adekvat smärtskattning. Generellt hade vårdpersonalen en positiv inställning till utbildning inom området smärtbedömning och även en stor intention att smärtskatta och göra detta korrekt. Det kunde ses att vårdpersonalens fördomar och attityder till äldres smärta påverkade smärtbedömningen. Slutsats: Smärtskattning av den äldre patienten är av största vikt för att minska smärta, lidande och andra följdtillstånd som obehandlad smärta orsakar. Med stöd från den samlade litteraturen, anses även att utbildning av personalen är ett mycket viktigt sätt att utveckla och förbättra smärtbedömningen inom vården.Many people over the age of 65 are living with pain. It’s a part of the nurse profession to assess and evaluate pain. Purpose: The purpose of this literature review was by existing research explore nurses knowledge and attitudes towards pain assessment and pain measurement in the care of elderly patients. Methods: In this literature review the databases Cinahl and Pubmed were used. Results: The results in this study are based on 10 articles. 7 quantitative, 2 qualitative and 1 were both methods was used. Factors that influenced how the patients’ pain was assessed by the health care givers was experience and education, attitudes and different obstacles that made adequate assessments difficult, such as patients having cognitive impairment and lack of time to perform assessment. In general, the caregivers had a positive attitude towards education about pain assessment and a great intention to assess pain correctly. However, it could be shown that negative attitudes and prejudices against pain in the older patient and how it should manifest affected how the pain assessment was performed. Conclusions: Negative attitudes regarding aging that is still exists in our society is affecting the health care of the individual. The authors believe, in support of the reviewed literature, that education is an important way to improve and develop the pain assessment performance.

Desenvolver condições de estabilidade e projeto de controladores para controle de atitude de corpos rígidos sujeitos a atrasos no tempo é o objetivo desta dissertação. O modelo utilizado, escrito na forma de equação diferencial atrasada, advém das equações cinemática e dinâmica do corpo rígido modificadas considerando atrasos temporais. Estes atrasos podem representar latências dos sensores e atuadores, além de tempo de processamento de dados (e.g., cômputo dos sinais de controle) e de transmissão de dados quando os elementos do sistema de controle estão conectados por redes comunicação. Em particular, são supostos atrasos desconhecidos e variantes no tempo, o que lhes confere generalidade maior do que os casos abordados até então na literatura, onde os poucos trabalhos que abordaram o problema aprensentam resultados dependentes do valor exato do atraso ou o assumem constante, o que na prática dificilmente é verificado. As condições obtidas, escritas na forma de teoremas, são baseadas em sua maioria na teoria de Lyapunov-Krasovskii. Outro aspecto que diferencia este trabalho em relação aos demais é que os teoremas são formulados como desigualdades matriciais lineares (LMIs, em inglês). A formulação por LMIs é vantajosa não só pelas excelentes propriedades computacionais das LMIs (resolução em tempo polinomial), mas também porque as condições são escritas com variáveis, reduzindo o conservadorismo dos resultados e permitindo a automação do processo de verificação de estabilidade e projeto de controladores, o que também é uma contribuição desta dissertação. Além disso, os controladores possuem performance garantida segundo o critério H∞ , isto é, além de estabilidade, este tipo de controlador tem um nível mínimo de atenuação de perturbações assegurado.
Developing stability and controller design conditions for rigid body attitude control subjected to time delays is the goal of this dissertation. The rigid body model, written in form of functional differential equation, stems from the kinematic and dynamic rigid body equations, modified to take time delays into account. Such time delays may represent sensor and actuator latency, processing time (e.g., computing control signals) and transmission lags when the control system elements are connected by communication networks. In particular, time delays are considered unknown and time-varying, which makes them generalizations of previous results in literature, where the scarce works to tackle the problem present results dependent on the exact time delay value, which is hardly verified in practice. The proposed conditions, written as theorems, are mostly based on Lyapunov-Krasovskii theory. Another aspect that sets this work apart is that theorems are formulated as linear matrix inequalities (LMIs). LMI formulation is advantageous not only for its excellent computational properties (polynomial time solving), but also for the conditions are written with variables, which reduces results' conservatism e enables automating stability verification and controller design, which is a contribution of this work as well. In addition, controllers attain guaranteed performance according to H∞ criterion, that is, besides stability, this kind of controller presents a known minimum level of perturbation attenuation.

Full textAbstract:
L'estimation de l'attitude (ou orientation) est un problème récurrent de nombreuses applications allant de la robotique aérienne ou sous-marine en passant par des applications médicales (surveillance de patients, réhabilitation), mais aussi jeux vidéo, etc. L'objectif de cette thèse est d'évaluer l'apport des approches ensemblistes dans le cadre de l'estimation de l'attitude à partir de données issues de triaxes accéléromètres (A), magnétomètres (M) et gyromètres (G). Dans un premier temps, on s'intéresse aux mouvements "quasi-statiques" et l'estimation de l'attitude est réalisée à partir de mesures AM. On aborde ensuite le cas des mouvements dynamiques, en considérant l'ensemble des mesures AGM. Le problème du choix de la paramétrisation de l'attitude a été abordé et on a comparé les résultats obtenus et le temps calcul pour des modélisations avec les angles de Cardan et le quaternion unitaire. Les algorithmes développés ont été validés en simulation et avec des données réelles. Les résultats ont été comparés avec ceux fournis par des algorithmes de l'état de l'art, par exemple SIVIA. La deuxième partie du manuscrit est consacrée à au diagnostic des capteurs de la centrale inertielle avec des approches ensemblistes. Les algorithmes développés dans la première partie du travail sont adaptés afin de pouvoir détecter et localiser un défaut dans l'ensemble des capteurs considérés.

Full textAbstract:
This report studies the development of a Multiplicative Extended Kalman Filter for orbit and attitude estimation for the 10times10times20 cm CubeSat at the Norwegian University of Science and Technology (NTNU). The filter was developed in a tightly coupled manner with respect to the GPS attitude solution, based on data from differential carrier phase measurements. These measurements are aided by measurements from a three-axis magnetometer, and inertial measurements from a gyroscope. Four antennas are virtually mounted on the satellite to obtain three baselines of 1 m each. The MEKF is complemented by an integer ambiguity resolution method, which makes sure that the solution for a GPS signal is not accepted until the integrity check value for all baselines is below the acceptance threshold. Until the ambiguities are resolved, the Multiplicative EKF is reliant upon the gyro measurements, and the magnetometer. The filter has been simulated with various attitude maneuvers.The MEKF performs orbit estimation based on measurements from GPS position, velocity, and timing data, from which it estimates the Keplerian orbital parameters to determine the orbit of the craft. It operates as an ordinary EKF for this purpose. Simulation shows that the filter is able to determine the attitude and orbit of the spacecraft from the given measurements, and that it is robust to a temporary loss of the GPS measurements. However, the orbit estimator assumes a circular orbit. The quality of orbit estimates are therefore dependent on the eccentricity of the orbit.

Full textAbstract:
Smärta är något subjektivt och det är bara patienten som kan säga hur ont han har. Smärtskattning ger sjuksköterskan en uppfattning om patientens upplevda smärta. Sjuksköterskor kommer ofta i kontakt med patienter med smärta, därav vikten av att kunna skatta smärta hos en patient på ett adekvat sätt. Olika smärtskattningsinstrument har tagits fram och är ett hjälpmedel till sjuksköterskan vid smärtskattning. Syftet med denna studie är att få en ökad kunskap och insikt i smärtskattningen ur en sjuksköterskas perspektiv. Vidare frågeställningar är vilka metoder som används vid smärtskattning, hur instrumenten fungerar i den kliniska vardagen samt sjuksköterskornas attityder gentemot smärtskattning. Metoden för datainsamlingen var att intervjua 9 sjuksköterskor på två ortopedavdelningar. Analysen skedde enligt en modifierad manifest innehållsanalys där fyra huvudkategorier arbetades fram. Det är individuellt hur sjuksköterskor smärtskattar en patient. Är patienten orienterad till tid och rum används visuell analog skala (VAS). Är det en patient med kognitiv nedsättning tittar sjuksköterskan på rörel-semönster eller frågar om smärta. VAS är det instrument som är mest känt. Fördelen med VAS är att det är lättdokumenterat. Nackdelen är att vissa patienter lär sig vad som ska sägas för att få smärtstillande.Pain is something subjective and it is only the patient who knows how much pain he has. Pain measurement gives the nurse a perception of the patients’ experience of pain. Nurses often come in contact with patients with pain and that is why it is important to assess the patients’ pain adequately. Different instruments for pain assessment have been developed and are a complement to the nurse in pain measurement. The aim of this study is to get better knowledge and insight into pain measurement from a nurse’s perspective. The study also examines which methods are used in pain measurement, how assessments function in every day medical practise and nurses’ attitudes towards pain measurement. The method of data collection was to interview 9 nurses at two orthopaedic wards. The analysis was done by modified manifest content analysis where four main categories were compiled. Nurse’s pain measurement is individual. If the patient is oriented to time and room the nurse uses visual analoge scale (VAS). If the patient suffers from cognitively dysfunction the nurse looks at the movement pattern or asks about pain. VAS is the tool that is most common. The advantage by using VAS is easy to document. The disadvantage is that some patients learn what to say to get painrelieving.

Full textAbstract:
This dissertation describes the development of an instrument to assess students' attitudes toward science. The rationale for developing a new instrument is presented in the context of a review of existing instruments. As discussed in the literature review, many existing instruments are based on ill-defined theoretical constructs, and include statements that do not appear to be assessing the single construct of attitude toward science. In addition, existing instruments do not distinguish between biological and physical science. Thus, the purpose of this study was to carefully define the construct, attitude toward science, and develop an attitude instrument to reflect that construct and to distinguish between biological and physical science. For this study, biological science was defined as any of the branches of science dealing with living things, such as genetics, entomology, or anatomy. Physical science was defined as any of the branches of science dealing with non-living things, such as physics, geology, chemistry, or earth science. Once the Likert-scale instrument was developed, it was piloted on a sample population of students in science classes at a suburban, southwestern high school. Their responses were used to do item analyses and to calculate validity and reliability. Principal-component analysis was also performed to try to identify sub-scales. The results of the data analysis were used to select items for a final scale. The final instrument consists of two parallel forms of 20 items each. For each form, 12 items refer to science in general, four to biological science, and four to physical science. The test-retest reliability coefficients of the final instruments are 0.768 for Form A and 0.788 for Form B. The parallel-forms reliability coefficient of the instrument is 0.93. The construct validity coefficients of the final instruments, compared to Germann's Attitude Toward Science in School Assessment, is 0.82 for Form A and 0.85 for Form B. Inter-item consistency, measured by Cronbach's alpha coefficient, is 0.91 for Form A and 0.89 for Form B.

Full textAbstract:
Thesis advisor: Larry H. LudlowRecent estimates suggest there are roughly 1.6 million homeless children and this number is growing (National Center on Family Homelessness, 2011). This trend is particularly worrisome given that homeless children face a number of obstacles within society and education, not the least of which is negative teacher attitudes (Swick, 2000; U.S. Department of Education, 2002). This study's primary research question addressed whether a set of underlying dimensions could be identified and used to effectively measure teacher attitudes toward homeless students. A necessary part of answering this research question involved the development of a measurement scale. Both Classical Test Theory and Item Response Theory analyses aided in the elimination process of items in order to create the final Teacher Attitudes toward Homeless Students (TAHS) assessment, which includes an attitudes scale and subscales, and a related knowledge scale. The final outcome was a set of 43 items, across eight dimensions, which could effectively be used to measure teacher attitudes toward homeless students. Additionally, the findings upheld the principles of Rasch measurement, including unidimensionality, a hierarchical ordering of items, and a continuum of the construct definition. In other words, the findings indicate that the TAHS scale was successfully developed according to explicit a priori measurement criteria. Moreover, additional correlational and regression analyses provided empirical construct and convergent validity evidence for the TAHS scale. It was also found that attitudes differed slightly for teachers of various backgrounds and experiences, but when analyzed collectively these variables were not significantly related to teacher attitudes toward homeless students. Additionally, there was only a weak relationship between teachers' attitudes and their knowledge about homelessness. Overall the TAHS scale allows for reliable and accurate measurement of teacher attitudes toward homeless students from which valid inferences can be made. The TAHS scale scores and score descriptors can be used to help teacher interpret their attitude. This has the potential for a direct impact in creating equal educational opportunities for homeless students as teachers become aware of their attitude and make positive changes

Full textAbstract:
The purpose of this research programme was to propose a new structure for judo coaching. Judo coaching predominantly uses traditional methods emphasising progression through belts rather than success in competition as the measure of achievement. The research programme examined this issue in four stages involving seven studies. Stage 1 involved a qualitative examination of five elite coaches on what constitutes an effective coach, leading to the initial development of a 39-item judo coaching scale. Given the importance of demonstrating measures are valid, stage 2 investigated the validity of the scale among judo players and coaches. Factor analytic studies on data from 260 (130 coaches and 130 players) yielded a 7-factor solution; 1) Coaching is about winning, 2) Attitudes to coaching at different levels, 3) Attitudes to judo structure, 4) Relationships with players, 5) Presentational issues, 6) Technical knowledge link to coach level, and 7) Coach-player interactions. Multisample confirmatory factor analysis found support for the invariance of the model between coaches and players, thereby showing that relationships are consistent between different groups. Stage 3 used a multi-method approach, combining quantitative and qualitative methods. Responses to the judo coaching scale indicated perceptions of coach effectiveness vary as a function of being a player or a coach, and by level of participation (elite-v-non-elite). Qualitative results emphasise the importance of emotional control, an aspect not focused on in the interviews completed in stage 1. Stage 4 of the research investigated relationships between judo coaching scale scores and emotional intelligence. The study also investigated levels of emotional intelligence between elite and club coaches. High emotional intelligence is associated is proposed to be indicative of being able to manage the emotional states of other people and so should be a desirable quality in coaches. Results show significant relationship between judo coaching scale score and emotional intelligence factors, with further analysis showing that elite coaches reported higher emotional intelligence scores than club coaches. Based on the findings from the studies completed above, a revised judo coaching structure is presented. An elite structure should be based on players having specific performance targets including technical and tactical skills, psychological, and physiological, aligning judo more closely with the structure used in other Olympic sports. Coaches should also be given targets related to developing emotional control among players and instilling players with a self-belief to attain performance targets related to the above. Effective integration and usage of such personnel is required including developing and inculcating sport science knowledge into the practice of elite coaches, and then modifying this knowledge for use in the club system. It is hoped that findings from this research stimulates discussion, and action in the British Judo Association to revise the current system, which could lead to better judo coaching, better players, and ultimately enhanced Olympic success at London 2012.

Full textAbstract:
The employment of embedded cameras in navigation and guidance of Unmanned Aerial Vehicles (UAV) has attracted the focus of many academic researches. In particular, for the multirotor UAV, the camera is widely employed for applications performed at indoor environments, where are less access to the GNSS signal and higher electromagnetic interference. Nevertheless, in most researches, the images captured by the camera are usually adopted to aid in the linear position/velocity estimation, but not specifically for assisting in the attitude determination process. This dissertation proposes an attitude determination method for multirotor UAVs using pairs of vector measurements taken from one downward facing strapdown camera and angular velocity measurements from gyros. The method consists in three modules. The first detects and identifies landmarks from the captured images. The second module computes the vector measurements related to the direction between the landmarks and the camera. The third module executes the attitude estimation from the vector measurements given by the second module. The employed estimation method consists in a version of the Multiplicative Extended Kalman Filter (MEKF) with sequential update. The proposed method was evaluated via Monte Carlo simulations using Simulink 3D Animation. During the evaluation, the method presented effectiveness and satisfactory results in most of the simulated cases. Finally, future works are suggested for the potential continuation of this research.

Full textAbstract:
European nations, built on democratic foundations, rely on participation that is inclusive of all groups. Among efforts to support social cohesion in Europe, investigating the development of intercultural attitudes—attitudes toward others on the basis of their intersecting group memberships—is a crucial area of research. Further, examining attitudes among adolescents is useful because of their growing capacity to understand complex systems, while still being engaged in formal education in which interventions aimed at developing positive attitudes are often applied. In this dissertation, I used data from the 2009 IEA ICCS (International Civic and Citizenship Education Study) to examine determinants of intercultural attitudes among adolescents (n=16,847) in seven countries across Europe—the United Kingdom (England only), Sweden, Switzerland, Spain, Bulgaria, Poland, and Greece—focusing on cultural contexts and school climates. First, I established the measurement invariance of a variety of measures of intercultural attitudes to support the validity of cross-cultural comparison, using a novel approach in the Bayesian framework. Using this method, I was able to validly compare intercultural attitudes across contexts in Europe, and these findings are interpreted and discussed. Then, I examined the ways in which intergroup contact, gender, and school climates were associated with intergroup attitudes across these seven countries. I found limited evidence of an association between native-born and immigrant contact and positive intercultural attitudes. However, I found that positive intercultural attitudes were consistently associated with positive and democratic school climates, as well as with gender and attitudes toward gender equality. In this dissertation, I present these findings, as well as provide interpretation, discussion, and future directions with regard to educational interventions.Culture, Communities, and Education

Full textAbstract:
Les travaux sur la résistance du consommateur fournissent une meilleure compréhension des manifestations et des facteurs situationnels déclenchant ces comportements. Afin d'aller plus loin dans l'identification des caractéristiques du consommateur résistant et des processus psychologiques qui le poussent à agir, nous proposons d'explorer l'existence d'une disposition individuelle stable – la propension à résister du consommateur (PRC) – susceptible d'expliquer la tendance de certains consommateurs à s'opposer à des formes d'influence marchande.L'objectif de cette recherche est donc (1) de proposer une conceptualisation de la propension à résister du consommateur comme variable individuelle centrale explicative du comportement de résistance ; (2) d'en fournir un outil de mesure fiable et valide ; (3) d'en déterminer l'impact sur les comportements de consommation et enfin (4) de tester le rôle différentiel de la situation et de cette variable dans la détermination des comportements de résistance.La mise en œuvre d'une double étude qualitative (focus groups et entretiens individuels) a permis de définir le construit et d'explorer sa dimensionnalité. Une échelle de mesure est ensuite validée sur deux dispositifs d'influence (la publicité et la vente) et confirme l'existence de deux profils de PRC : un profil orienté « confrontation » et un profil orienté « évitement ».Une expérimentation menée auprès de 500 personnes représentatives de la population française met en évidence un lien fort entre le niveau de PRC et les réactions négatives des consommateurs aux sollicitations marchandes. Elle montre que la PRC est un meilleur prédicteur du comportement de résistance dans les situations à faible potentiel de résistance, alors que la situation prédit mieux la résistance lorsque l'intensité de l'influence ou de la manipulation perçue est élevée. Les résultats de cette recherche invitent à considérer deux profils distincts de consommateurs résistants qui appellent des stratégies marketing différenciéesCurrent researches on consumer resistance allow a better understanding of the manifestations and situational factors triggering these behaviors. In order to go further in the identification of the psychological processes underlying those behaviors, we propose exploring an individual disposition - consumers' propensity to resist (CPR)-.that may explain the tendency of some consumers to oppose marketers' influenceThe objective of this research is to (1) offer a conceptualization the consumer's propensity to resist the consumer, (2) to provide a reliable and valid measurement tool of this concept, (3 ) to determine the impact of this individual trait on some consumers behaviors and finally (4) to test the differential role of the situation and CPR in determining resistance behaviors.The implementation of a dual qualitative study (focus groups and in-depth interviews) helped to define the construct and explore its dimensionality. A measurement scale is then validated on two mechanisms of influence (advertising and sales) and confirms the existence of two profiles of CPR: a profile linked to “confrontation” and the other linked to “avoidance”.An experiment conducted with 500 people representative of the french population demonstrates a strong link between levels of CPR and negative reactions of consumers to marketers' demands. It shows that CPR is a better predictor of resistant behaviors in situations where the intensity of influence or the perceived manipulation is low, while the situation is a better predictor of resistance when the intensity of the influence or perceived manipulation is high The results of this research invite to consider two distinct profiles of resistant consumers that may deserve differentiated marketing strategies
