A motivação de licenciandos em música sob a perspectiva da teoria da autodeterminação

This research had as main aim to verify the motivational quality of music students at four public universities in the Northeast of Brazil, based on the Self-Determination Theory (SDT). This perspective was proposed by Edward Deci and Richard Ryan (1985, 2000, 2008a, 2008b), and considers the qualitative aspects of motivation. It defends that the individuals have a natural tendency to self-regulation; it adopts the concept of internalizations through a continuum of self-determination conceived in the mini-theory of organismic integration. The research presents a descriptive, exploratory and correlational approach. To collect data, it was submitted a self-report questionnaire, based on the Academic Motivational Scale, translated and validated by Guimarães and Bzuneck (2008), which allow us to verify the motivation types according to a selfdeterminational continuum. According to this application, the instrument has shown evidence of satisfactory validity, with a good internal consistence and correlations from weak to moderate scale. The obtained data were collected from 380 music students, analyzed through a descriptive and inferential statistics, considering a few procedures: frequencies, averages, standard deviation, factorial analysis, internal consistence analysis through Cronbach Alpha, Pearson’s correlational analysis and variance analysis. The analyzed data show that high averages in the evaluation of self-determined motivation and low evaluation in demotivation and less autonomy motivation. Many students revealed strong intention to conclude the course. It was identified less autonomous motivation and more motivation among the students with intention to work in other areas, some of them concluded the final training process in Music Course, and say that they are in this course because they had no other option. We conclude that those graduated in Music Course, represented in this sample, show a good motivational quality. But after a few time there is a tendency in decreasing autonomous motivation because of some requirements of an academic course. In this sense, the courses must create strategies to maintain a self-determined behavior so that students can realize their autonomous motivation, identifying its importance, value and meaning along the Course.

Validity of the portable piko-6 spirometer used for screening obstructive airway diseases in community pharmacy practice

Background: Obstructive airway diseases (OADs) are among the leading causes of morbidity and mortality worldwide. Shortness of breath (SOB) is the main symptom associated with OADs. International guidelines from the Global Initiative for Chronic Lung Disease (GOLD) and the Global Initiative for Asthma (GINA) have recommended spirometry as an indispensable tool for the diagnosis of asthma and chronic obstructive pulmonary diseases (COPD), but spirometry is rarely used in family practice. Simple and reliable diagnostic tools are necessary for screening community patients with onset of OADs for timely management. Purpose: This thesis examined screening utility of the PiKo-6 forced expiratory volume in one second (pFEV₁) , in six second (pFEV₆), and the pRatio ( pFEV₁/pFEV₆) in SOB patients for OADs in community pharmacy settings. FEV₆ has recently been suggested an excellent surrogate for Forced Vital Capacity (FVC), which requires maximum exhalation of the lungs. Methods: Patients with SOB symptoms who were prescribed pulmonary inhalers, by their family physicians, were recruited via community pharmacies. Trained pharmacists collected two PiKo-6 tests to assess the repeatability of the PiKo-6 device. All patients performed laboratory spirometry ( FEV₁, FVC and FEV₁/FVC) to obtain physician diagnosis of their OADs. The results of the PiKo-6 spirometer and laboratory spirometer were compared. In addition, the PiKo-6 pRatio and laboratory FEV₁/FVC were assessed against physician diagnosed COPD. Results: Sixty three patients volunteered to perform the PiKo-6 spirometry. Of these, 52.4 % were men (age 53.9 ± 15.3 years; BMI 31.9 ± 7.40 kg/m2). Repeated testing with pFEV₁, pFEV6 and pRatio correlated significantly (within correlation, r = 0.835, p-Value≤ 0.05 ; 0.872, p- Value≤ 0.05; and 0.664, p-Value≤ 0.05). In addition, pFEV₁, pFEV6 and pRatio correlated significantly with FEV₁, FVC and FEV₁/FVC, respectively (between correlation = 0.630, p- Value≤ 0.05 ; 0.660, p-Value≤ 0.05 and 0.580, p-Value≤ 0.05). The cut-off value corresponding to the greatest sum of sensitivity and specificity of pRatio for physician-diagnosed COPD was <0.80, the sensitivity and specificity were 84 % and 50%, respectively. Conclusions The portable PiKo-6 correlates moderately well with the standard spirometry, when delivered by community pharmacists to patients with OADs. The PiKo-6 spirometer may play a role in screening patients suspected of having an OAD in community pharmacies that may benefit from early physician diagnosis and appropriate management.

Que dit la science à propos des intelligences multiples?

Dans le débat sur l’unicité ou la multiplicité de l’intelligence, Gardner prend nettement position en faveur des intelligences multiples (IM). Son approche soulève toutefois au moins neuf critiques : la confusion entre l’intelligence et le talent, une rigueur scientifique insuffisante, l’absence de réelles nouveautés, le caractère arbitraire des critères utilisés, les problèmes de l’interdépendance des IM, du réel statut des IM, l’ignorance des résultats des approches factorielles et le refus de considérer les différences entre les groupes, de la mesure des IM. La validité des applications des IM dans le milieu scolaire peut également être mise en doute. En conclusion, nous nous interrogeons sur la raison du succès de la théorie des IM.

Peripheral refraction validity of the Shin-Nippon SRW5000 autorefractor

PURPOSE: To investigate the operation of the Shin-Nippon/Grand Seiko autorefractor and whether higher-order aberrations affect its peripheral refraction measurements. METHODS: Information on instrument design, together with parameters and equations used to obtain refraction, was obtained from a patent. A model eye simulating the operating principles was tested with an optical design program. Effects of induced defocus and astigmatism on the retinal image were used to calibrate the model eye to match the patent equations. Coma and trefoil were added to assess their effects on the image. Peripheral refraction of a physical model eye was measured along four visual field meridians with the Shin-Nippon/Grand Seiko autorefractor SRW-5000 and a Hartmann-Shack aberrometer, and simulated autorefractor peripheral refraction was derived using the Zernike coefficients from the aberrometer. RESULTS: In simulation, the autorefractor's square image was changed in size by defocus, into rectangles or parallelograms by astigmatism, and into irregular shapes by coma and trefoil. In the presence of 1.0 D oblique astigmatism, errors in refraction were proportional to the higher-order aberrations, with up to 0.8 D sphere and 1.5 D cylinder for ±0.6 μm of coma or trefoil coefficients with a 5-mm-diameter pupil. For the physical model eye, refraction with the aberrometer was similar in all visual field meridians, but refraction with the autorefractor changed more quickly along one oblique meridian and less quickly along the other oblique meridian than along the horizontal and vertical meridians. Simulations predicted that higher-order aberrations would affect refraction in oblique meridians, and this was supported by the experimental measurements with the physical model eye. CONCLUSIONS: The autorefractor's peripheral refraction measurements are valid for horizontal and vertical field meridians, but not for oblique field meridians. Similar instruments must be validated before being adopted outside their design scope.

The Validity of Broad and Narrow Personality Traits For Predicting Job Performance: The Differential Effects of Time

Research into the dynamicity of job performance criteria has found evidence suggesting the presence of rank-order changes to job performance scores across time as well as intraindividual trajectories in job performance scores across time. These findings have influenced a large body of research into (a) the dynamicity of validities of individual differences predictors of job performance and (b) the relationship between individual differences predictors of job performance and intraindividual trajectories of job performance. In the present dissertation, I addressed these issues within the context of the Five Factor Model of personality. The Five Factor Model is arranged hierarchically, with five broad higher-order factors subsuming a number of more narrowly tailored personality facets. Research has debated the relative merits of broad versus narrow traits for predicting job performance, but the entire body of research has addressed the issue from a static perspective -- by examining the relative magnitude of validities of global factors versus their facets. While research along these lines has been enlightening, theoretical perspectives suggest that the validities of global factors versus their facets may differ in their stability across time. Thus, research is needed to not only compare the relative magnitude of validities of global factors versus their facets at a single point in time, but also to compare the relative stability of validities of global factors versus their facets across time. Also necessary to advance cumulative knowledge concerning intraindividual performance trajectories is research into broad vs. narrow traits for predicting such trajectories. In the present dissertation, I addressed these issues using a four-year longitudinal design. The results indicated that the validities of global conscientiousness were stable across time, while the validities of conscientiousness facets were more likely to fluctuate. However, the validities of emotional stability and extraversion facets were no more likely to fluctuate across time than those of the factors. Finally, while some personality factors and facets predicted performance intercepts (i.e., performance at the first measurement occasion), my results failed to indicate a significant effect of any personality variable on performance growth. Implications for research and practice are discussed.

The Responsiveness, Content Validity, and Convergent Validity of the Measure Yourself Concerns and Wellbeing (MYCaW) Patient-Reported Outcome Measure

Objective Measure Yourself Concerns and Wellbeing (MYCaW) is a patient-centred questionnaire that allows cancer patients to identify and quantify the severity of their ‘Concerns’ and Wellbeing, as opposed to using a pre-determined list. MYCaW administration is brief and aids in prioritising treatment approaches. Our goal was to assess the convergent validity and responsiveness of MYCaW scores over time, the generalisability of the existing qualitative coding framework in different complementary and integrative healthcare settings and content validity. Methods Baseline and 6-week follow-up data (n=82) from MYCaW and FACIT-SpEx questionnaires were collected for a service evaluation of the ‘Living Well With The Impact of Cancer’ course at Penny Brohn Cancer Care. MYCaW construct validity was determined using Spearman's Rank Correlation test, and responsiveness indices assessed score changes over time. The existing qualitative coding framework was reviewed using a new dataset (n=158) and coverage of concern categories compared to items of existing outcome measures. Results Good correlation between MYCaW and FACIT-SpEx score changes were achieved (r= -0.57, p≥0.01). MYCaW Profile and Concern scores were highly responsive to change: SRM=1.02 and 1.08; effect size=1.26 and 1.22. MYCaW change scores showed the anticipated gradient of change according to clinically relevant degrees of change. Categories including ‘Spirituality’, ‘weight change’ and ‘practical concerns’ were added to the coding framework to improve generalisability. Conclusions MYCaW scores were highly responsive to change, allowing personalized patient outcomes to be quantified; the qualitative coding framework is generalisable across different oncology settings and has broader coverage of patient-identified concerns compared with existing cancer-related patient-reported outcome measures.

The Reliability and Validity of a Child and Adolescent Participation in Decision Making Questionnaire

Background
There is a growing impetus across the research, policy and practice communities for children and young people to participate in decisions that affect their lives. Furthermore, there is a dearth of general instruments that measure children and young people’s views on their participation in decision making. This paper presents the reliability and validity of the Child and Adolescent Participation in Decision Making Questionnaire (CAP-DMQ) and specifically looks at a population of looked-after children where a lack of participation in decision making is an acute issue.
Methods
The participants were 151 looked after children and adolescents between 10-23 years of age who completed the 10 item CAP-DMQ. Of the participants 113 were in receipt of an advocacy service that had an aim of increasing participation in decision-making with the remaining participants not having received this service.
Results
The results showed that the CAP-DMQ had good reliability (Cronbach’s alpha = .94) and showed promising uni-dimensional construct validity through an exploratory factor analysis. The items in the CAP-DMQ also demonstrated good content validity by overlapping with prominent models of child and adolescent participation (Lundy 2007) and decision making (Halpern 2014). A regression analysis showed that age and gender were not significant predictors of CAP-DMQ scores but receipt of advocacy was a significant predictor of scores (effect size d=.88), thus showing appropriate discriminant criterion validity.
Conclusion
Overall, the CAP-DMQ showed good reliability and validity. Therefore, the measure has excellent promise for theoretical investigation in the area of child and adolescent participation in decision making and equally shows empirical promise for use as a measure in evaluating services which have increasing the participation of children and adolescents in decision making as an intended outcome.

A literature review to Examine the Validity and Reliability of group poster presentations as an assessment method of a module in an undergraduate nursing degree programme

The introduction of a poster presentation as a formative assessment method over a multiple choice examination after the first phase of a three phase “health and well-being” module in an undergraduate nursing degree programme was greeted with a storm of criticism from fellow lecturers stating that poster presentations are not valid or reliable and totally irrelevant to the assessment of learning in the module. This paper seeks to investigate these criticisms by investigating the literature regarding producing nurses fit for practice, nurse curriculum development and wider nurse education, the purpose of assessment, validity and reliability to critically evaluate the poster presentation as a legitimate assessment method for these aims.

Discussion about the validity of virtual practices in subjects in the radioccomunication area. Results of the educational experience

[EN]Nowadays we are living a virtual learning boom. Mainly, it is due to two facts: first, easy spreading of the knowledge and second, virtual learning is cheaper than classic instrumentation laboratories. This cost is even bigger in radiocommunication and high frequency area. In fact, time and time again there are more universities that give up offering the realization of laboratory practice. In the present report we propose a discussion about the increase of virtual practices when contact with instrumentation and circuits is basic. The experience of seven lecturers of the Communications Engineering Group (GIC) will be exposed.

Experiências de Combate e a sua Relação com a Sintomatologia Associada à Perturbação Pós-Stress Traumático em Veteranos da Guerra Colonial Portuguesa

Objectivos: O presente estudo avaliou a relação entre diversos aspectos objectivos e subjectivos inerentes às experiências de combate/guerra e sintomatologia associada à Perturbação Pós-Stress Traumático. Os instrumentos de auto-resposta utilizados na colheita dos dados foram analisados quanto às suas principais propriedades psicométricas. Métodos: A amostra foi composta por 105 combatentes da Guerra Colonial Portuguesa. Foram utilizados os seguintes instrumentos de avaliação: um questionário sóciodemográfico de auto-resposta para a caracterização da amostra, o Posttraumatic Stress Disorder Checklist (para militares), o Peritraumatic Dissociative Experiences Questionnaire, o Questionário de Experiências de Combate e duas escalas do Deployment Risk and Resilience Inventory, nomeadamente a Difficult Livings and Working Environment Scale e a Perceived Threat Scale. Resultados: O estudo das qualidades psicométricas dos instrumentos apresenta uma consistência interna superior a .86 e uma estabilidade temporal superior a .79. A análise factorial do Peritraumatic Dissociative Experiences Questionnaire apresenta bons valores na medida de Kaiser-Meyer-Olkin e no teste de esfericidade de Bartlett. Na rotação de Varimax é extraído um factor, predizendo a sua unidimensionalidade, que explica cerca de 70% da variância total do questionário. Os resultados relativos à validade divergentediscriminante indicam, por si só, que esta se apresenta de forma clara entre os instrumentos estudados (PCL-M, PDEQ, DLWES e PTS) no subgrupo com PTSD, com excepção da verificada entre o PCL-M e o PDEQ.. Quanto à validade de critério, constatam-se diferenças entre os subgrupos com e sem PTSD. Através do método da regressão linear múltipla, duas das seis variáveis têm, isoladamente, um peso preditivo significativo para a PTSD, nomeadamente a frequência de exposição a situações típicas e objectivas de combate/ guerra e os desconfortos diários durante a(s) comissão(ões). Ao considerarmos as variáveis no seu conjunto, aquelas que mais contribuem são a dissociação peritraumática e os desconfortos diários durante a(s) comissão(ões). Conclusão: Constata-se que os factores peritraumáticos em estudo desempenham um importante papel no desenvolvimento da sintomatologia inerente à PTSD. /
