Enabling constructive alignment in programming instruction

In this thesis, simple methods have been sought to lower the teacher’s threshold to start to apply constructive alignment in instruction. From the phases of the instructional process, aspects that can be improved with little effort by the teacher have been identified. Teachers have been interviewed in order to find out what students actually learn in computer science courses. A quantitative analysis of the structured interviews showed that in addition to subject specific skills and knowledge, students learn many other skills that should be mentioned in the learning outcomes of the course. The students’ background, such as their prior knowledge, learning style and culture, affects how they learn in a course. A survey was conducted to map the learning styles of computer science students and to see if their cultural background affected their learning style. A statistical analysis of the data indicated that computer science students are different learners than engineering students in general and that there is a connection between the student’s culture and learning style. In this thesis, a simple self-assessment scale that is based on Bloom’s revised taxonomy has been developed. A statistical analysis of the test results indicates that in general the scale is quite reliable, but single students still slightly overestimate or under-estimate their knowledge levels. For students, being able to follow their own progress is motivating, and for a teacher, self-assessment results give information about how the class is proceeding and what the level of the students’ knowledge is.

Vaccination Competence - The Concept and Evaluation

The purpose of this two-phase study was to define the concept of vaccination competence and assess the vaccination competence of graduating public health nurse students (PHN students) and public health nurses (PHNs) in Finland, with the goal of promoting and maintaining vaccination competence and developing vaccination education. The first phase of the study included semi-structured interviews with vaccination professionals, graduating PHN students and clients (a total of n=40), asking them to describe vaccination competence as well as the factors strengthening and weakening it. The data were analyzed through content analysis. In the second phase of the study, structured instruments were developed, and vaccination competence of PHN students (n=129) in Finland and PHNs (n=405) was assessed using a self-assessment scale (VAS) and taking a knowledge test. PHNs were used as a reference group, enabling us to determine whether a satisfactory level of vaccination competence was achieved by the end of studies, or whether it was gained through work experience vaccinating clients. The data were collected from five polytechnic institutions and seven health centers located in various parts of the country. The data were collected using instruments developed for this study, and were analyzed statistically. In the first phase, based on the results of the interviews, vaccination competence was defined as a large multi-faceted entity, including the concepts of competent vaccinator, competent implementation of the vaccination, and the outcome of the implementation. Semi-structured interviews revealed that factors strengthening and weakening vaccination competence were connected to the vaccinator, the client being vaccinated, the vaccination environment and vaccinator education. On the whole, factors strengthening and weakening vaccination were the opposite of each other. In the second phase, on the self-assessment of vaccination competence, students rated themselves as significantly lower than working professionals. On the knowledge test, the percentage of correct answers was lower for students than PHNs. When all background variables were taken into account in multivariate analysis, there was no longer a significant difference between the students and PHNs on the self-assessment. However, in multivariate analysis, the PHNs still performed better than students on the knowledge test. For this study, a satisfactory level of vaccination competence was defined as a mean of 8.0 on the self-assessment and 80% correct answers on the knowledge test. Based on these criteria, students almost reached the level of satisfactory in their overall self-assessment, and PHNs did. Both groups, however, did rank themselves as satisfactory in some sum variables. On the knowledge test the students did not achieve a level of satisfactory (80%) in their total score, though PHNs did. As before, both groups did achieve a level of satisfactory in several sum variables. Further research and development should focus on vaccination education, the testing of vaccination competence and vaccination practices in clinical practice, as well as on developing the measurement tools.

Kirurgisten potilasohjeiden laatu ja valmius tukea voimavaraistavaa potilasohjausta sekä infektioiden torjuntaan liittyvä sisältö

Hoitotyössä infektioiden torjunnan painopistealueena on ollut lisätä potilaiden osallistuvuutta voimavaraistavalla potilasohjauksella. Potilasohjauksen apuna käytetään usein kirjallisia potilasohjeita, joiden rakenne ja laatu tulee olla hyvä. Lisäksi potilasohjeiden tulee omata valmiuksia tukea voimavaraistavaa potilasohjausta. Kirjalliset potilasohjeet ovat hyvä potilasohjauksen keino, mutta systemaattinen tieto potilasohjeiden laadusta, valmiuksista tukea voimavaraistavaa potilasohjausta sekä infektioiden torjunnan sisällöstä puuttuu. Tutkimuksen tarkoituksena oli analysoida Suomen yliopistosairaaloiden kirurgisten potilasohjeiden infektioiden torjuntaan liittyvää sisältöä. Lisäksi oltiin kiinnostuneita potilasohjeiden laadusta hyvien kirjallisten potilasohjeiden ominaispiirteiden toteutumisessa sekä potilasohjeiden valmiuksista tukea voimavaraistavaa potilasohjausta. Tutkimuksen aineistona oli viiden yliopistosairaalan kirurgisille aikuispotilaille tarkoitetut potilasohjeet (N = 237). Organisaatioittain joka viides potilasohje (n = 50) analysoitiin potilasohjeiden laadun osalta sisällönerittelyllä ja aikaisemmin kehitetyn mittarin avulla (Salanterä ym. 2004). Deduktiivisella sisällönanalyysillä analysoitiin potilasohjeiden valmiuksia tukea voimavaraistavaa potilasohjausta, jonka ulottuvuuksien esiintyvyyden arviointiasteikko oli kehitetty tätä tutkimusta varten. Induktiivisella sisällönerittelyllä analysoitiin infektioiden torjuntaan liittyvä sisältö. Potilasohjeiden laadussa oli paljon vaihtelua, ja vain 36 % (n = 18) potilasohjeista oli julkaistu viimeisen kolmen vuoden (2010–2012) aikana. Potilasohjeet olivat ulkoasultaan selkeitä ja johdonmukaisia, jolloin kirjallisten potilasohjeiden ominaisuuksista parhaiten toteutuivat ulkoasun sekä kielen ja rakenteen ominaisuudet. Potilasohjeet kuvasivat toimenpidettä ja siitä selviytymistä, antaen parhaiten valmiuksia tukea toiminnallista ja bio-fysiologista selviytymistä potilasohjauksella. Infektioiden torjuntaan liittyvä sisältö oli pääasiassa esitetty epäsuorasti toisen asian kautta. Infektioiden syntyyn tai torjuntaan ei viitattu, vaan asiaa tarkasteltiin muusta näkökulmasta esimerkiksi ylipainon ja ihon kunnon osalta. Yleisin infektioiden torjuntaan liittyvä sisältö koski käsihygieniaa, vaikka sen toteuttamista ei opastettu tai ohjeistettu. Tutkimus tarjoaa lähtökohdan kehittää potilasohjeiden infektioiden torjuntaan liittyvää sisältöä sekä potilaan osallistuvuuden lisäämistä. Erityisesti tulisi kehittää potilaan osallistuvuuden tukemista voimavaraistavalla potilasohjauksella. Jatkotutkimuksena tulisi kartoittaa potilaiden tarpeet infektioiden torjunnan sisällöstä sekä kehittää kansallinen ohjeistus potilasohjeiden infektioon torjuntaan liittyvästä sisällöstä ja rakenteesta.

Conceptualizing and measuring human anxiety on the Internet

Since the 1990’s, the Internet has played a central role in our daily lives. The Internet is an integral part of our personal, business, family, research, entertainment, academic and social life. However, there are social implications in using the Internet that are dependent on categories such as gender, age, ethnicity and cultural attributes. This social aspect can play a detrimental role in the expression of human anxiety on the Internet. An anxiety is a complex phenomenon that requires further elaboration. Thus, the aim of this thesis is to investigate human anxiety, or specifically, whether Internet anxiety can be conceptualized and measured. This thesis utilizes literature, qualitative and quantitative research methodologies, and a triangulation validation approach to conceptualize and measure the Internet anxiety phenomenon. In particular, the aim is to explore anxiety levels of Internet participants to develop and validate an Internet anxiety scale based on earlier research on Internet anxiety. The results of the dissertation present a two phase study. In Phase I, a smaller set of studies were conducted with a limited sample size. In Phase II, the research topic was investigated using 385 participants. Based on a number of studies or experiments, the state-of-the-art discovered in this thesis is creation, design, and validation of two scales, the Self-Assessment Scale (SAS) and a Modified Internet Anxiety Scale (MIAS) for measuring users’ anxieties on the Internet. The result of this dissertation is a conceptualization and measurement of various types of Internet anxiety and measurement of affective feelings of users on the Internet. As a proof-of-concept of measuring Internet anxiety, this thesis describes the author’s implementation of three sets of tools: MyAnxiety, introducing Internet anxieties types; Intelligentia, for collecting Internet anxieties types; and MyIAControl tool, implemented as a browser plug-in, for measuring affective feelings of users on the Internet. Conclusions drawn from the results show that these empirically validated scales and tools might be useful for researchers and practitioners in understanding and measuring the Internet anxiety phenomenon further.

Late-life depression, heart failure and frontal white matter hyperintensity: a structural magnetic resonance imaging study

The relevance of the relationship between cardiac disease and depressive symptoms is well established. White matter hyperintensity, a bright signal area in the brain on T2-weighted magnetic resonance imaging scans, has been separately associated with cardiovascular risk factors, cardiac disease and late-life depression. However, no study has directly investigated the association between heart failure, major depressive symptoms and the presence of hyperintensities. Using a visual assessment scale, we have investigated the frequency and severity of white matter hyperintensities identified by magnetic resonance imaging in eight patients with late-life depression and heart failure, ten patients with heart failure without depression, and fourteen healthy elderly volunteers. Since the frontal lobe has been the proposed site for the preferential location of white matter hyperintensities in patients with late-life depression, we focused our investigation specifically on this brain region. Although there were no significant group differences in white matter hyperintensities in the frontal region, a significant direct correlation emerged between the severity of frontal periventricular white matter hyperintensity and scores on the Hamilton scale for depression in the group with heart failure and depression (P = 0.016, controlled for the confounding influence of age). There were no significant findings in any other areas of the brain. This pattern of results adds support to a relationship between cardiovascular risk factors and depressive symptoms, and provides preliminary evidence that the presence of white matter hyperintensities specifically in frontal regions may contribute to the severity of depressive symptoms in cardiac disease.

Aerobic exercise in adolescence : self-efficacy and stage of change

The purpose of this cross-sectional exploratory study was to examine the relationships among self-efficacy, stage of change, and exercise behaviour in a sample of younger (Grade 9) and older (Grade 12) adolescents. A secondary objective of this study was to apply the transtheoretical model of Stage of Change, as a measure of intention to change, in order to discover the applicability of the model to an adolescent cohort in relation to exercise behaviour. This five-stage model is a self-report measure of an individual's readiness to adopt a new behaviour (e.g., regular exercise). The transtheoretical model incorporates Bandura's self-efficacy factor, which is purported to be a predictive measure of exercise behaviour and a covariant of stage. Exercise behaviour was measured with the Physical Activity Scale, and the University of Rhode Island Change Assessment Scale (URleA) was used to measure the stage of change and self-efficacy variables. The results of this study indicated significant differences between younger and older adolescents, and between males and females in their exercise behaviour. No significant differences were found for grade and gender on stage of change as measured by either a single-item question or a continuous measure of stage. Although grade and gender subgroups were not significantly different in their self-efficacy, significant interaction was found in the grade*gender variable.

The association of faculty's teaching philosophy and teaching behaviour, and critical thinking and self- direction in learning

The intent in this study was to investigate in what ways teachers· beliefs about education and teaching are expressed in the specific teaching behaviours they employ, and whether teaching behaviours, as perceived by their students, are correlated with students· critical thinking and self-directed learning. To this end the relationships studied were: among faCUlty members· philosophy of teaching, locus of control orientation, psychological type, and observed teaching behaviour; and among students· psychological type, perceptions of teaching behaviour, self-directed learning readiness, and critical thinking. The overall purpose of the study was to investigate whether the implicit goals of higher education, critical thinking and self-direction, were actually accounted for in the university classroom. The research was set within the context of path-goal theory, adapted from the leadership literature. Within this framework, Mezirow·s work on transformative learning, including the influences of Habermas· writings, was integrated to develop a theoretical perspective upon which to base the research methodology. Both qualitative and quantitative methodologies were incorporated. Four faCUlty and a total of 142 students participated in the study. Philosophy of teaching was described through faCUlty interviews and completion of a repertory grid. Faculty completed a descriptive locus of control scale, and a psychological type test. Observations of their teaching behaviour were conducted. Students completed a Teaching Behaviour Assessment Scale, the Self-Directed Learning Readiness Scale, a psychological type test, and the Watson-Glaser Critical Thinking Appraisal. A small sample of students were interviewed. Follow-up discussions with faculty were used to validate the interview, observation, teaching behaviour, and repertory grid data. Results indicated that some discrepancies existed between faculty's espoused philosophy of teaching and their observed teaching behaviour. Instructors' teaching behaviour, however, was a function of their personal theory of practice. Relationships were found between perceived teaching behaviour and students· self-directed learning and critical thinking, but these varied across situations, as would be predicted from path-goal theory. Psychological type of students and instructor also accounted for some of the variability in the relationships studied. Student psychological type could be shown as a partial predictor of self-directed learning readiness. The results were discussed in terms of theory development and implications for further research and practice.

Profils des toxicomanes judiciarisés en traitement dans deux centres de réadaptation publics au Québec

L’objectif de la présente étude consiste à tenter de mieux connaître la population judiciarisée qui se présente en traitement pour des problèmes de toxicomanies. Deux cent seize clients admis en traitement dans deux centres de réadaptation en toxicomanie du Québec constituent l’échantillon. Ces sujets ont répondu à l’Indice de gravité d’une toxicomanie (IGT-ASI), au Millon Clinical Multiaxial Inventory (MCMI), à l’Inventaire de personnalité Jesness, et au University of Rhodes Island Change Assessment Scale (URICA). Ces outils nous serviront à décrire la popula~tion étudiée. L’analyse des données nous entraîne dans une réflexion à deux niveaux. D’une part, l’observation de problématiques multiples dans la population à l’étude nous questionne sur les possibilités de mettre en place des services de traitement adéquats pour ces personnes qui apparaissent éprouver des problèmes d’adaptation à plusieurs niveaux. D’autre part, le niveau des problèmes de toxicomanie des personnes référées par le système de justice nous interroge sur la pertinence de certaines de ces références.

Evaluación de la validez de la escala llanto para el dolor en neonatos y menores de cinco años

Introducción: La escala LLANTO para dolor es una escala que hasta la fecha ha sido solo validada en población infantil española, actualmente no se conocen datos en población colombiana. Se pretende validar la escala de dolor LLANTO en pacientes neonatos y menores de 5 años, a través de su aplicación en pacientes atendidos en una de tres instituciones, además comparándola con las escalas FLACC y PIPP dependiendo de edad del paciente. Metodología: Se incluyeron niños con cualquier tipo de dolor, clasificándolos en dos grupos por edad: 1) neonatos y 2) niños entre 1 mes y 5 años de edad, que asistieron a la Fundación Cardioinfantil, Clínica Infantil Colsubsidio o al Hospital Universitario Mayor. Las escalas fueron aplicadas por dos residentes de pediatría y una enfermera especializada en el cuidado de población infantil. Para la prueba piloto se diseñó un cuestionario determinar dificultades en la aplicación de la escala LLANTO. Una vez corregidos los problemas identificados se procederá a la validación de la escala. Resultados: Se presentan los datos de la prueba piloto. Se incluyeron 8 neonatos y 8 niños entre 1 mes y 5 años, esta muestra fue obtenida en un periodo de un mes, con la encuesta se evaluó la aceptación y entendimiento de la escala LLANTO por parte de los evaluadores. La prueba piloto mostró resultados favorables en el 100% de los encuestados. Discusión: Se considera que la escala LLANTO no requiere cambios para continuar con su validación.

Evaluación del comportamiento en el recién nacido deficiente visual : un estudio de aplicación de la Escala de Brazelton.

Resumen tomado de la publicación

Efecto de la aplicación de un programa de estimulación cognitiva variando el formato de presentación en una muestra de pacientes con enfermedad de alzheimer leve y moderada.

Comparar a nivel cognitivo, funcional y conductual el efecto de la modalidad de intervención cognitiva, individual frente a la grupal, en dos grupos de pacientes con Enfermedad de Alzheimer (EA) que recibieron un programa de estimulación cognitiva y un grupo de pacientes con EA que estaba en lista de espera para recibir el mismo programa de intervención cognitiva. Se ha trabajado con una muestra conformada por 60 participantes que asistieron a la Asociación de Familiares de Enfermos de Alzheimer (AFA) Salamanca durante el año 2007. De la muestra, 15 participantes eran sujetos sanos a nivel cognitivo, los 45 restantes tenían diagnóstico de demencia según los criterios del Manual Diagnóstico y Estadístico de las Enfermedades Mentales. El rango de edad de los participantes oscilaba entre los 64 y los 86 años. La media de edad para el total de la muestra era de 75.45 años y una desviación típica de 4.50 años. Participaron 27 hombres y 33 mujeres. El grupo de pacientes con EA estaba conformado por 20 hombres y 25 mujeres. Los 45 pacientes con EA fueron distribuidos en 3 grupos, cada uno con 15 integrantes; de los cuales 15 participantes recibieron el programa de estimulación cognitiva en el formato individual (EAI), 15 pacientes recibieron el mismo programa en el formato grupa (EAG), y los demás estaban en lista de espera para recibir el mismo programa de intervención (EANT). El programa de estimulación cognitiva se llevo a cabo en un periodo de tres meses por grupo, con una frecuencia de tres veces por semana y una duración de una hora por sesión, para un total de 36 sesiones. Al inicio del programa de estimulación cognitiva, los participantes de los tres grupos estaban equiparados en cuento a rendimiento cognitivo evidenciado en las puntuaciones pretest en el Alzheimer Disease Assessment Scale, asimismo en cuanto al rendimiento funcional en la Escala de Evaluación Rápida de Discapacidad y en el rendimiento conductual Neuropsychiatric Inventory Questionary y en la Escala de Depresión de Cornell. Recibir un programa de estimulación cognitiva resulta especialmente significativo para los pacientes con EA respecto a la progresión del declive que a nivel cognitivo, funcional y conductual van experimentando. Al realizar las comparaciones respecto al formato de intervención: individual frente a grupal puede notarse que el formato de intervención individual ofrece mayores beneficios a los pacientes con EA reduciendo especialmente la sintomatología depresiva. Los resultados indican que tanto los pacientes que recibieron el programa de estimulación cognitiva en el formato individual como grupal demostraron mayor rendimiento a nivel cognitivo, funcional y conductual que los pacientes que se encontraban en lista de espera para recibir el mismo programa de intervención cognitiva. Asimismo al realizar las comparaciones tanto entre los pacientes EAI frente a los EAG, se pudo observar que el formato de intervención cognitiva individual ofrece mayores beneficios a los pacientes con EA, especialmente a nivel cognitivo y conductual reduciendo la manifestación de la sintomatología depresiva.

The effect of the GENTLE/s robot-mediated therapy system on arm function after stroke

Objective: To evaluate the effect of robot-mediated therapy on arm dysfunction post stroke. Design: A series of single-case studies using a randomized multiple baseline design with ABC or ACB order. Subjects (n = 20) had a baseline length of 8, 9 or 10 data points. They continued measurement during the B - robot-mediated therapy and C - sling suspension phases. Setting: Physiotherapy department, teaching hospital. Subjects: Twenty subjects with varying degrees of motor and sensory deficit completed the study. Subjects attended three times a week, with each phase lasting three weeks. Interventions: In the robot-mediated therapy phase they practised three functional exercises with haptic and visual feedback from the system. In the sling suspension phase they practised three single-plane exercises. Each treatment phase was three weeks long. Main measures: The range of active shoulder flexion, the Fugl-Meyer motor assessment and the Motor Assessment Scale were measured at each visit. Results: Each subject had a varied response to the measurement and intervention phases. The rate of recovery was greater during the robot-mediated therapy phase than in the baseline phase for the majority of subjects. The rate of recovery during the robot-mediated therapy phase was also greater than that during the sling suspension phase for most subjects. Conclusion: The positive treatment effect for both groups suggests that robot-mediated therapy can have a treatment effect greater than the same duration of non-functional exercises. Further studies investigating the optimal duration of treatment in the form of a randomized controlled trial are warranted.

Pathological Love: Impulsivity, Personality, and Romantic Relationship

Introduction: Pathological love (PL)-behavior characterized by providing repetitive and uncontrolled care and attention to the partner in a romantic relationship-is a rarely studied condition, despite not being rare and causing suffering. This study aims at investigating impulsivity, personality, and characteristics related to the romantic relationship in this population. Methods: Eighty-nine individuals (50 with PL; 39 individuals with no psychiatric disorder) were compared regarding impulsivity, personality, type of attachment, satisfaction with romantic relationship, and love style. Results: Individuals with PL have higher levels of impulsivity (P<.001; Barratt Impulsiveness Scale), higher self-transcendence, that is, are more unconventional and hold sense of communjon with a widerreality (P<.001; Temperament and Character Inventory) and keep dissatisfactory romantic relationships (P<.001; Adapted Relationship Assessment Scale). Conclusion: Individuals with PL present personality traits and relationship aspects that must be taken into account in devising assessment and therapeutic strategies for this population.

Associação entre resposta clínica e eventos adversos ao metilfenidato e genes dopaminérgicos e serotoninérgicos em crianças e adolescentes com transtorno de déficit de atenção/hiperatividade

Introdução: Poucos estudos sobre a farmacogenética do Transtorno de Déficit de Atenção/Hiperatividade (TDAH) foram conduzidos até o momento, apesar da extensa literatura sobre a participação de genes na etiologia do TDAH. Os estudos farmacogenéticos podem auxiliar na identificação a priori dos indivíduos que se beneficiarão de determinados tratamentos e dos que possivelmente apresentarão intolerância aos agentes farmacológicos. A maior parte dos estudos, até o momento, avaliou genes do sistema dopaminérgico e resultou em achados tanto positivos quanto negativos. Métodos: em um estudo naturalístico avaliamos os efeitos dos polimorfismos dos genes candidatos dopaminérgicos (DRD4, DAT1) e serotoninérgicos (HTR1B, HTR2A e 5-HTT) na resposta ao tratamento em 111 pacientes para os quais foi prescrito metilfenidato. As medidas de desfecho (Swanson, Nolan, and Pelham scale - versão IV – anexo I, Children Global Assessment Scale – anexo II, Barkley’s Stimulants Side Effects Rating Scale – anexo III) foram aplicadas no momento de avaliação e um mês após a intervenção. Resultados: Participaram do estudo 111 famílias de crianças e adolescentes eurobrasileiros de ambos os sexos que apresentavam TDAH segundo o DSM-IV. Estes pacientes foram consecutivamente triados no Programa de Déficit de Atenção/Hiperatividade do Hospital de Clínicas de Porto Alegre entre janeiro de 2003 e maio de 2004. Não foi detectada associação significativa entre os polimorfismos dos genes dopaminérgicos e serotoninérgicos avaliados e a resposta ao metilfenidato ou presença de eventos adversos. Conclusão: Os achados deste estudo quanto aos genes dopaminérgicos são negativos, concordando com três outros estudos disponíveis na literatura. Este foi o primeiro estudo a avaliar o efeito dos genes serotoninérgicos isolados na resposta ao metilfenidato e na presença de eventos adversos. Não foi encontrada nenhuma associação significativa. Os resultados dos estudos existentes são de difícil comparação devido à grande variabilidade metodológica existente entre os estudos. Assim, ensaios controlados multicêntricos prospectivos com maiores tamanhos amostrais são necessários para desvendar o papel dos genes candidatos na resposta ao tratamento para o TDAH.
