Young adults and the 5 a day campaign: perceived benefits and barriers of eating more fruits and vegetables

Although consuming adequate amounts of fruits and vegetables reduces the risk of developing chronic diseases, it is widely recognized that young adults’ intakes are currently well below the Department of Health’s recommended five portions a day, with men consuming even less than women. One approach in the UK has been to introduce health campaigns such as the 5 A DAY programme; however, little is currently known about how well their messages are understood amongst young adults. This study examined current knowledge of the 5 A DAY message in young adults, as well as the perceived benefits and remaining barriers towards consuming more fruits and vegetables. In total, four focus groups were conducted using male (n = 22) and female (n = 18) students at the University of Reading. Content analysis revealed that while participants were aware of the 5 A DAY recommendation, there was widespread confusion regarding the detail. In addition, men were less accepting of the message than women, reporting greater disbelief and a lack of motivation to increase intake. Finally, a range of barriers was reported by participants of both genders, despite the perceived beneficial effects for health and appearance. The results illustrate a considerable gap between awareness and knowledge of the 5 A DAY message, and underscore the challenge that changing behaviour in young adults represents. As well as stepping up education- and skill-based health campaigns, more targeted gender specific interventions will be needed to achieve sustained increases in fruit and vegetable intake.

Drivers' ratings of different components of their own driving skill: a greater illusion of superiority for skills that relate to accident involvement

Different components of driving skill relate to accident involvement in different ways. For instance, while hazard-perception skill has been found to predict accident involvement, vehicle-control skill has not. We found that drivers rated themselves superior to both their peers and the average driver on 18 components of driving skill (N = 181 respondents). These biases were greater for hazard-perception skills than for either vehicle-control skills or driving skill in general. Also, ratings of hazard-perception skill related to self-perceived safety after overall skill was controlled for. We suggest that although drivers appear to appreciate the role of hazard perception in safe driving, any safety benefit to be derived from this appreciation may be undermined by drivers' inflated opinions of their own hazard-perception skill. We also tested the relationship between illusory beliefs about driving skill and risk taking and looked at ways of manipulating drivers' illusory beliefs.

Investigation of language and motor skills in Serbian speaking children with specific language impairment and in typically developing children

Specific language impairment (SLI) is usually defined as a developmental language disorder which does not result from a hearing loss, autism, neurological and emotional difficulties, severe social deprivation, low non-verbal abilities. Children affected with SLI typically have difficulties with the acquisition of different aspects of language and by definition, their impairment is specific to language and no other skills are affected. However, there has been a growing body of literature to suggest that children with SLI also have non-linguistic deficits, including impaired motor abilities. The aim of the current study is to investigate language and motor abilities of a group of thirty children with SLI (aged between 4 and 7) in comparison to a group of 30 typically developing children matched for chronological age. The results showed that the group of children with SLI had significantly more difficulties on the language and motor assessments compared to the control group. The SLI group also showed delayed onset in the development of all motor skills under investigation in comparison to the typically developing group. More interestingly, the two groups differed with respect to which language abilities were correlated with motor abilities, however Imitation of Complex Movements was the unique skill which reliably predicted expressive vocabulary in both typically developing children and in children with SLI.

Skilloscopy: Bayesian modeling of decision makers' skill

This paper proposes and demonstrates an approach, Skilloscopy, to the assessment of decision makers. In an increasingly sophisticated, connected and information-rich world, decision making is becoming both more important and more difficult. At the same time, modelling decision-making on computers is becoming more feasible and of interest, partly because the information-input to those decisions is increasingly on record. The aims of Skilloscopy are to rate and rank decision makers in a domain relative to each other: the aims do not include an analysis of why a decision is wrong or suboptimal, nor the modelling of the underlying cognitive process of making the decisions. In the proposed method a decision-maker is characterised by a probability distribution of their competence in choosing among quantifiable alternatives. This probability distribution is derived by classic Bayesian inference from a combination of prior belief and the evidence of the decisions. Thus, decision-makers’ skills may be better compared, rated and ranked. The proposed method is applied and evaluated in the gamedomain of Chess. A large set of games by players across a broad range of the World Chess Federation (FIDE) Elo ratings has been used to infer the distribution of players’ rating directly from the moves they play rather than from game outcomes. Demonstration applications address questions frequently asked by the Chess community regarding the stability of the Elo rating scale, the comparison of players of different eras and/or leagues, and controversial incidents possibly involving fraud. The method of Skilloscopy may be applied in any decision domain where the value of the decision-options can be quantified.

Investigating the relationship between competence and patient outcome with CBT

Little is understood about the relationship between therapist competence and the outcome of patients treated for common mental health disorders. Understanding the relationship between competence and patient outcome is of fundamental importance to the dissemination and implementation of Cognitive Behavioural Therapy (CBT). The current study extends existing literature by exploring the relationship between CBT competence and patient outcome in routine clinical practice within the framework of the British Government’s Improving Access to Psychological Therapies (IAPT) programme. Participants comprised 43 therapists treating 1247 patients over a training period of one year. Results found little support of a general association between CBT competence and patient outcome; however significantly more patients of the most competent therapists demonstrated a reliable improvement in their symptoms of anxiety than would be expected by chance alone, and fewer experienced no reliable change. Conversely, significantly more patients treated by the least competent therapists experienced a reliable deterioration in their symptoms than would be expected. The implications of these results for the dissemination and implementation of CBT are discussed.

The Nurse Professional Competence (NPC) scale : self-reported competence among nursing students on the point of graduation

BACKGROUND: International organisations, e.g. WHO, stress the importance of competent registered nurses (RN) for the safety and quality of healthcare systems. Low competence among RNs has been shown to increase the morbidity and mortality of inpatients. OBJECTIVES: To investigate self-reported competence among nursing students on the point of graduation (NSPGs), using the Nurse Professional Competence (NPC) Scale, and to relate the findings to background factors. METHODS AND PARTICIPANTS: The NPC Scale consists of 88 items within eight competence areas (CAs) and two overarching themes. Questions about socio-economic background and perceived overall quality of the degree programme were added. In total, 1086 NSPGs (mean age, 28.1 [20-56]years, 87.3% women) from 11 universities/university colleges participated. RESULTS: NSPGs reported significantly higher scores for Theme I "Patient-Related Nursing" than for Theme II "Organisation and Development of Nursing Care". Younger NSPGs (20-27years) reported significantly higher scores for the CAs "Medical and Technical Care" and "Documentation and Information Technology". Female NSPGs scored significantly higher for "Value-Based Nursing". Those who had taken the nursing care programme at upper secondary school before the Bachelor of Science in Nursing (BSN) programme scored significantly higher on "Nursing Care", "Medical and Technical Care", "Teaching/Learning and Support", "Legislation in Nursing and Safety Planning" and on Theme I. Working extra paid hours in healthcare alongside the BSN programme contributed to significantly higher self-reported scores for four CAs and both themes. Clinical courses within the BSN programme contributed to perceived competence to a significantly higher degree than theoretical courses (93.2% vs 87.5% of NSPGs). SUMMARY AND CONCLUSION: Mean scores reported by NSPGs were highest for the four CAs connected with patient-related nursing and lowest for CAs relating to organisation and development of nursing care. We conclude that the NPC Scale can be used to identify and measure aspects of self-reported competence among NSPGs.

Gerentes de projeto : um estudo sobre a relação entre perfis psicodemográficos, desempenho e progressão profissional

Dada a crescente estruturação das organizações permanentes em organizações temporárias, aqui representadas como projetos, há uma demanda proporcional por profissionais qualificados que atuem como os maestros dessas empreitadas – os gerentes de projetos (GP’s). Esta pesquisa de dissertação de mestrado tem por objetivo estudar como diferentes traços psicodemográficos, à saber: gênero, etnia, orientação sexual e aparência física, impactam na vida e na progressão profissional do GP que os detenha, pela perspectiva deste profissional. Na busca por possíveis respostas para essa questão, percorremos a teoria procurando os subsídios necessários ao GP para exercer satisfatoriamente sua atividade e ascender na carreira. Vimos que as hard skills desses profissionais são desenhadas e enriquecidas por meio das metodologias e boas práticas trazidas pelas diversas associações internacionais de gestão de projetos. Todavia, as ações prescritivas dessas metodologias apenas delineiam os contornos mais amplos das soft skills. Este conjunto de habilidades se mostrou fundamental para o GP em seu trabalho, sendo empiricamente apreendido e enriquecido pela experiência prática. Ademais, a progressão na carreira de GP é percebida frente à crescente complexidade dos projetos à ele subordinados, como também é percebida ao enveredar por caminhos mais estratégicos e menos operacionais. Calçamos a pesquisa sobre a cultura brasileira, usada como arcabouço para entender como tais profissionais exercem suas relações de liderança, comunicação, respeito e colaboração para com seus stakeholders, ou seja, suas soft skills, e orquestram as atividades necessárias para a conclusão satisfatória de um projeto. Sobre tal base, buscamos entender possíveis preconceitos e barreiras impostas às diferentes psicodemografias para, em sequência, observar quais impactos são percebidos pelos GP’s no exercício de suas atividades, bem como na progressão de suas carreiras. Trouxemos do campo entrevistas com vários GP’s de diferentes psicodemografias. A análise do discurso nos emprestou o ferramental para estudar os dados de campo, e abarcar conclusões sustentadas pela base teórica. Como resultado, percebemos que a cultura brasileira ainda apresenta mecanismos de dominação encarnados por um grupo androcêntrico, etnicamente branco e heterossexual, com prescrições e normas sobre a aparência física. Vimos também que as soft skills são influenciadas pela cultura local, principalmente quando são exercidas por minorias rejeitadas pelo grupo dominante. Percebemos a existência de portas e tetos de vidro na vida profissional de um GP que encarne determinados traços psicodemográficos, bem como uma introjeção de tal lógica androcêntrica. Tais profissionais exercem suas funções com um custo maior do que aquele realizado por homens, brancos, heterossexuais e de boa aparência, bem como precisam se mostrar resilientes à tal dominação. As barreiras para o gênero feminino também se erguem quando a GP mulher, mesmo em um contexto de liderança de uma organização temporária, exerce a maternidade.

O motor das transformações

A presente Tese tem por objetivo propor um sistema de inovação permanente para a área do Agronegócio do setor da Horticultura da Região Serrana do Estado do Rio de Janeiro. Este trabalho parte da suposição de que existe um potencial não explorado de inovação pelo trabalho atualizável mediante um modelo referencial composto por um conjunto de indutores denominados de INDILABs – Indutores da Inovação Laboral: a tecnologia, a gestão, o processo de cognição e a atitude e ação. A Tecnologia promove mudanças econômicas, políticas e culturais e influencia o trabalho, a vida e o processo de cognição. A Gestão promove a personalização dos indivíduos e desenvolver a criatividade. O Processo de Cognição contribui para articular e harmonizar os sistemas sociais e deve ser centrado nos valores éticos e humanos para que haja equilíbrio entre o ser e o seu valor de uso, enquanto que a Atitude e Ação buscam consolidar os movimentos mais criativos, autônomos, humanos, prazerosos e desafiadores nos espaços coletivos. Discute-se a essencialidade da capacidade de inovação para a continuidade dos sistemas produtivos, sendo considerada uma condição fundamental para a sobrevivência dos negócios, dos empregos, do trabalho e da renda. Relaciona-se o Estado com a inovação, afirmando que além de apoiar o desenvolvimento de atividades econômicas, dos indivíduos e da sociedade, ele deve assegurar a continuidade dos sistemas produtivos pela capacidade de inovação por meio e mediante o trabalho. Utilizando procedimentos metodológicos baseados no estruturalismo, buscou-se a estrutura subjacente às práticas dos trabalhos dos agricultores familiares e suas relações com o sistema de apoio ao desenvolvimento da inovação. A coleta de dados para a pesquisa foi realizada com base em entrevistas individuais e em grupos, formais e informais, através de seminário específico e da observação do contexto e exame de documentos. O modelo referencial de inovação proposto visa fundamentar a formulação de políticas públicas nas seguintes áreas: a) Desenvolvimento do empreendedorismo; b) Formação e Capacitação do agricultor e de mão de obra; c) Promover a cooperação e inter-relacionamento institucional; d) Comunicação e difusão; e) Apoio a Comercialização; e f) Atuar em programas de diversificação da Produção.

Estado nutricional, desempenho motor e marcadores dermatoglíficos em escolares púberes

A fase da puberdade é o período em que ocorrem as maiores transformações características da adolescência. Por essa razão, este estudo objetivou identificar o estado nutricional, desempenho motor e marcadores dermatoglíficos em 2363 escolares púberes selecionados de forma estratificada, de ambos os sexos, com idades variando de 6 a 15 anos, matriculados no Ensino Fundamental (2ª a 9ª Séries) do ensino público no estado do Rio Grande do Norte. Foram avaliados o estado nutricional (Índice de Massa Corporal); as qualidades físicas básicas ( testes de coordenação, equilíbrio, agilidade, flexibilidade, força e velocidade); o potencial genético (método da dermatoglifia) e o estágio maturacional (auto avaliação de Tanner); Com relação ao estado nutricional observou-se que escolares acima do peso apresentam valores mais baixos em relação ao seu desempenho motor sendo esses valores, mais significativos nos meninos. No que se refere à maturação sexual, os resultados apontaram que os meninos atingem os estágios maturacionais primeiro que as meninas, não tendo encontrado correlação entre o potencial genético e os demais indicadores o que nos permite concluir que os escolares do estado do Rio Grande do Norte, principalmente os do sexo masculino sofrem influência significativa de seu estado nutricional e seu estágio maturacional no que diz respeito ao seu desempenho motor. Essa dissertação apresenta relação de interdisciplinaridade, tendo o seu conteúdo uma aplicação nos campos da Educação Física, Nutrição, Medicina e Enfermagem.

Reflexões sobre a construção e evolução de conceitos geométricos nas séries intermediárias do ensino fundamental

This thesis represents a didactic research linked to the Post-graduation Programme in Education of the Universidade Federal do Rio Grande do Norte which aimed to approach the construction of the geometrical concepts of Volume of the Rectangular Parallelepiped, Area and Perimeter of the Rectangle adding a study of the Area of the Circle. The research was developed along with students from the 6th level of the Elementary School, in a public school in Natal/RN. The pedagogical intervention was made up of three moments: application of a diagnostic evaluation, instrument that enabled the creation of the teaching module by showing the level of the geometry knowledge of the students; introduction of a Teaching Module by Activities aiming to propose a reflexive didactic routing directed to the conceptual construction because we believed that such an approach would favor the consolidation of the learning process by becoming significant to the apprentice, and the accomplishment of a Final Evaluation through which we established a comparison of the results obtained before and after the teaching intervention. The data gathered were analyzed qualitatively by means of a study of understanding categories of mathematical concepts, in addition to using descriptive statistics under the quantitative aspect. Based on the theory of Richard Skemp, about categorization of mathematical knowledge, in the levels of Relational and Instrumental Understanding were achieved in contextual situations and varied proportions, thus enabling a contribution in the learning of the geometrical concepts studied along with the students who took part in the research. We believe that this work may contribute with reflections about the learning processes, a concern which remained during all the stages of the research, and also that the technical competence along with the knowledge about the constructivist theory will condition the implementation of a new dynamics to the teaching and learning processes. We hope that the present research work may add some contribution to the teaching practice in the context of the teaching of Mathematics for the intermediate levels of the Elementary School

A dimensão social do desenho: um estudo sobre as interações no processo de (re) construção imagética da criança no Ensino Fundamental

In the historical-cultural perspective, the drawing is processed by means of a shared and complex way, under diverse relations with the other and with the immersed signs of the culture. That is, something constituted by the social interactions and that can modify the structure of the psychological functions, therefore as socialized sign, propitiates the incorporation of the functions socially. In this way, the figuration carrier sensitive and established meanings historically disclosing the shared experiences and the ways of the subject to think and perceive the world. Such reflections gave shape to the main problem of this research: how to think over about the drawing at the school to incide in the reconstruction of the childs imaginative language? Under such perspective, this work deals with the interactions in the production process of the drawing of the children in a context of teach-Iearning of the elementary school having as goal to analyze the interactions established in the cIassroom in the process of production of the drawings; to propose situations of learnings that favor the advance graphical expression of the students; and to identify in the interactive games some relations between body expression and drawing. For its accomplishment, it was opted for the construction process based in the collaborative investigation by the fact to propitiate negotiations, sharing and confrontation of ideas, becoming possible a joint construction of the knowledge. For this research, the researcher and the collaborating teacher, as well as the involved children, become themselves into co-authors of the context studied. As locus of the research, it was chosen a first cycle class, with 30 students, from Municipal School Profª. Emília Ramos (Natal/RN - Brazil), whose election took in account the fact of this school to constitute in a promotional space of reflections and professional development of teachers in service and, at the same time, for presentinglimitations theoretic- methodological in the field of teaching for Arts. In the process of the research, it was perceived that the children with the support of the verbal language formulates meanings on the seen and imagined object, printing lines and forms that if overlap to the physiological aspects of the visual perception. That is, the drawing discloses a reality appraised, enriched for the picked up vision of the image, but the meanings established for the author, or observer who becomes it perceivable and identified. In the systemizing situations, it was observed that the teaching-Iearning process of the drawing, implies a co-construction between teachers and learners. And, moreover, the necessity to interlace emotion and cognition by means of plastic-corporal interactions that foment drawing experiences, whose process concurs for the imagenative reconstruct of the apprentices

Quantitative comparison of mobility and gross motor function in Brazilian children with cerebral palsy

Background: Cerebral palsy (CP) presents changes in posture and movement as a core characteristic, which requires therapeutic monitoring during the habilitation or rehabilitation of children. Besides clinical treatment, it is fundamental that professionals use systems of evaluation to quantify the difficulties presented to the individual and assist in the organization of a therapeutic program. The aim of this study was to quantitatively verify the performance of children with spastic di-paresia type CP.Methods: The Pediatric Evaluation of Disability Inventory (PEDI) and Gross Motor Function Classification System (GMFM) tests were used and classification made through the GMFCS in the assessment of 7 patients with CP, 4 females and 3 males, average age of 9 years old.Results: According to GMFCS scales, 17% (n=1) were level II and 83% (n=6) were level III. The PEDI test and 88 GMFM items were used in the area of mobility. We observed that there was high correlation between mobility and gross motor function with Pearson's correlation coefficient =0.929) showing the likely impact of these areas in the functional skills and the quality of life of these patients.Conclusion: We suggest the impact of the limitation of the areas in functional skills and quality of life of these patients.

Bothropstoxin-I reduces evoked acetylcholine release from rat motor nerve terminals: Radiochemical and real-time video-microscopy studies

Understanding the biological activity profile of the snake venom components is fundamental for improving the treatment of snakebite envenomings and may also contribute for the development of new potential therapeutic agents. In this work, we tested the effects of BthTX-I, a Lys49 PLA2 homologue from the Bothrops jararacussu snake venom. While this toxin induces conspicuous myonecrosis by a catalytically independent mechanism, a series of in vitro studies support the hypothesis that BthTX-I might also exert a neuromuscular blocking activity due to its ability to alter the integrity of muscle cell membranes. To gain insight into the mechanisms of this inhibitory neuromuscular effect, for the first time, the influence of BthTX-I on nerve-evoked ACh release was directly quantified by radiochemical and real-time video-microscopy methods. Our results show that the neuromuscular blockade produced by in vitro exposure to BthTX-I (1 μM) results from the summation of both pre- and postsynaptic effects. Modifications affecting the presynaptic apparatus were revealed by the significant reduction of nerve-evoked [3H]-ACh release; real-time measurements of transmitter exocytosis using the FM4-64 fluorescent dye fully supported radiochemical data. The postsynaptic effect of BthTX-I was characterized by typical histological alterations in the architecture of skeletal muscle fibers, increase in the outflow of the intracellular lactate dehydrogenase enzyme and progressive depolarization of the muscle resting membrane potential. In conclusion, these findings suggest that the neuromuscular blockade produced by BthTX-I results from transient depolarization of skeletal muscle fibers, consequent to its general membrane-destabilizing effect, and subsequent decrease of evoked ACh release from motor nerve terminals. © 2012 Elsevier Ltd.
