International assessments of student science achievement, and growing evidence of students' waning interest in school science, have ensured that the development of scientific literacy continues to remain an important educational priority. Furthermore, researchers have called for teaching and learning strategies to engage students in the learning of science, particularly in the middle years of schooling. This study extends previous national and international research that has established a link between writing and learning science. Specifically, it investigates the learning experiences of eight intact Year 9 science classes as they engage in the writing of short stories that merge scientific and narrative genres (i.e., hybridised scientific narratives) about the socioscientific issue of biosecurity. This study employed a triangulation mixed methods research design, generating both quantitative and qualitative data, in order to investigate three research questions that examined the extent to which the students' participation in the study enhanced their scientific literacy; the extent to which the students demonstrated conceptual understanding of related scientific concepts through their written artefacts and in interviews about the artefacts; and the extent to which the students' participation in the project influenced their attitudes toward science and science learning. Three aspects of scientific literacy were investigated in this study: conceptual science understandings (a derived sense of scientific literacy), the students' transformation of scientific information in written stories about biosecurity (simple and expanded fundamental senses of scientific literacy), and attitudes toward science and science learning. The stories written by students in a selected case study class (N=26) were analysed quantitatively using a series of specifically-designed matrices that produce numerical scores that reflect students' developing fundamental and derived senses of scientific literacy. All students (N=152) also completed a Likert-style instrument (i.e., BioQuiz), pretest and posttest, that examined their interest in learning science, science self-efficacy, their perceived personal and general value of science, their familiarity with biosecurity issues, and their attitudes toward biosecurity. Socioscientific issues (SSI) education served as a theoretical framework for this study. It sought to investigate an alternative discourse with which students can engage in the context of SSI education, and the role of positive attitudes in engaging students in the negotiation of socioscientific issues. Results of the study have revealed that writing BioStories enhanced selected aspects of the participants' attitudes toward science and science learning, and their awareness and conceptual understanding of issues relating to biosecurity. Furthermore, the students' written artefacts alone did not provide an accurate representation of the level of their conceptual science understandings. An examination of these artefacts in combination with interviews about the students' written work provided a more comprehensive assessment of their developing scientific literacy. These findings support extensive calls for the utilisation of diversified writing-to-learn strategies in the science classroom, and therefore make a significant contribution to the writing-to-learn science literature, particularly in relation to the use of hybridised scientific genres. At the same time, this study presents the argument that the writing of hybridised scientific narratives such as BioStories can be used to complement the types of written discourse with which students engage in the negotiation of socioscientific issues, namely, argumentation, as the development of positive attitudes toward science and science learning can encourage students' participation in the discourse of science. The implications of this study for curricular design and implementation, and for further research, are also discussed.

Objective: To identify knowledge, attitudes and practices of child health nurses relating to infant wrapping as an effective settling/sleep strategy. Methods: A pre-test/post-test intervention design was used to explore knowledge, attitudes and practices relating to wrapping in a sample of child health nurses (n=182): a) pre-test survey; b) educational intervention incorporating evidence relating to infant wrapping; SIDS&KIDS endorsed infant wrapping pamphlet; Safe Sleeping recommendations. Emphasis was placed on infant wrapping as an effective settling strategy for parents to use as an alternative to prone positioning; c) post-test survey to evaluate intervention effectiveness. Results: Pretest results identified wide variation in nurses’ knowledge, attitudes and practices of infant wrapping as a settling/sleep strategy. The intervention increased awareness of wrapping guidelines and self-reported practices relating to parent advice. Significant positive changes in nurses’ awareness of wrapping guidelines (p<0.001); to wrap in supine position only (p<0.001); and parental advice to use wrapping as an alternative strategy to prone positioning to assist settling/sleep (p<0.01), were achieved post-test. Conclusions: Managing unsettled infants and promoting safe sleeping practices are issues routinely addressed by child health nurses working with parents of young infants. Queensland has a high incidence of prone sleeping. Infant wrapping is an evidence-based strategy to improve settling and promote supine sleep consistent with public health recommendations. Infant wrapping guidelines are now included in Queensland Health’s state policy and Australian SIDSandKids information relating to safe infant sleeping. In communicating complex health messages to parents, health professionals have a key role in reinforcing safe sleeping recommendations and offering safe, effective settling/sleep strategies to address the non-recommended use of prone positioning for unsettled infants.

Aim: This article reports the results of a study evaluating a preferred music listening intervention for reducing anxiety in older adults with dementia in nursing homes. Background. Anxiety can have a significant negative impact on older adults’ functional status, quality of life and health care resources. However, anxiety is often under-diagnosed and inappropriately treated in those with dementia. Little is known about the use of a preferred music listening intervention for managing anxiety in those with dementia.---------- Design: A quasi-experimental pretest and posttest design was used. ---------- Methods: This study aimed to evaluate the effectiveness of a preferred music listening intervention on anxiety in older adults with dementia in nursing home. Twenty-nine participants in the experimental group received a 30-minute music listening intervention based on personal preferences delivered by trained nursing staff in mid-afternoon, twice a week for six weeks. Meanwhile, 23 participants in the control group only received usual standard care with no music. Anxiety was measured by Rating Anxiety in Dementia at baseline and week six. Analysis of covariance (ANCOVA) was used to determine the effectiveness of a preferred music listening intervention on anxiety at six weeks while controlling for pretest anxiety, age and marital status. Results. ANCOVA results indicated that older adults who received the preferred music listening had a significantly lower anxiety score at six weeks compared with those who received the usual standard care with no music (F = 12Æ15, p = 0Æ001).---------- Conclusions: Preferred music listening had a positive impact by reducing the level of anxiety in older adults with dementia. Relevance to clinical practice. Nursing staff can learn how to implement preferred music intervention to provide appropriate care tailored to the individual needs of older adults with dementia. Preferred music listening is an inexpensive and viable intervention to promote mental health of those with dementia.

This paper reports on a small-scale study, which looked into the impact of metacognitive instruction on listeners’ comprehension. Twenty-eight adult, Iranian, high-intermediate level EFL listeners participated in a “strategy-based” approach of advance organisation, directed attention, selective attention, and self-management in each of four listening lessons focused on improving listeners’ comprehension of IELTS listening texts. A comparison of pretest and posttest scores showed that the “less-skilled” listeners improved more than “more-skilled” listeners in the IELTS listening tests. Findings also supported the view that metacognitive instruction assisted listeners in considering the process of listening input and promoting listening comprehension ability.

The research reported here addresses the problem of athlete off-field behaviours as they influence sports’ sponsors, particularly the achievement of sponsorship objectives. The question arises because of incidents of sponsorship contract cancellation following news-media reporting of athletes’ off-field behaviours. Two studies are used to investigate the research question; the first establishes the content of news-media reports, and the second tests the effects of news’ reports on athlete, team and sponsor evaluations using an experimental design. Key assumptions of the research are that sponsorship objectives are principally consumer-based and mediated. Models of sponsorship argue that sponsors aim to reach and influence consumers through sponsees. Assuming this pathway exists is central to sponsorship activities. A corollary is that other mediators, in this case the news-media, may also communicate (uncontrollable) messages such that a consumer audience may be told of negative news that may then be associated with the sponsor. When sponsors cancel contracts it is assumed that their goal is to control the links between their brand and a negative referent. Balance theory is used to discuss the potential effects of negative off-field behaviours of athletes on sponsor’s objectives. Heider’s balance theory (1958) explains that individuals prefer to evaluate linked individuals or entities consistently. In the sponsorship context this presents the possibility that a negative evaluation of the athlete’s behaviour will contribute to correspondingly negative evaluations of the athlete’s team and sponsors. A content analysis (Study 1) was used to survey the types of athlete off-field behaviours commonly reported in a newspaper. In order to provide a local context for the research, articles from the Courier Mail were sampled and teams in the National Rugby League (NRL) competition were the focus of the research. The study identified nearly 2000 articles referring to the NRL competition; 258 of those refer to off-field incidents involving athletes. The various types of behaviours reported include assault, sexual assault allegations, driving under the influence of alcohol, illicit drug use, breaches of club rules, and positive off-field activities (i.e., charitable activities). An experiment (Study 2) tested three news’ article stimuli developed from the behaviours identified in Study 1 in a between-subjects design. A measure of Identification with the Team was used as a covariate variable in the Multivariate Analysis of Covariance analysis. Social identity theory suggests that when an individual identifies with a group, their attitudes and behaviours towards both in- and out-group members are modified. Use of Identification with the Team as a covariate acknowledges that respondents will evaluate behaviours differently according to the attribution of those behaviours to an in- or out-group member. Findings of the research suggest that the news’ article stimuli have significant, large effects on evaluations of athlete off-field behaviour and athlete Likability. Consistent with pretest results, charitable fundraising is regarded as extremely positive; the athlete, correspondingly, is likable. Assault is evaluated as extremely negative, and the athlete as unlikable. DUI scores reveal that the athlete’s behaviour is very negative; however, the athlete’s likability was evaluated as neutral. Treatment group does not produce any significant effects on team or sponsor variables. This research also finds that Identification with the Team has significant, large effects on team variables (Attitude toward the Brand and Corporate Image). Identification also has a significant large effect on athlete Likability, but not on Attitude toward the Act. Identification with the Team does not produce any significant effects on sponsor variables. The results of this research suggest that sponsor’s consumer-based objectives are not threatened by newspaper reports linking athlete off-field behaviour with their brand. Evaluations of sponsor variables (Attitude toward the Sponsor’s Brand and Corporate Image) were consistently positive. Variance in that data, however, cannot be attributed to experimental stimuli or Identification with the Team. These results argue that respondents may regard sponsorships, in principle, as good. Although it is good news for sponsors that negative evaluations of athletes will not produce correspondingly negative evaluations of consumer-based sponsorship objectives, the results indicate problems for sponsorship managers. The failure of Identification with the Team to explain sponsor variable variance indicates that the sponsor has not been evaluated as a linked entity in a relationship with the sporting team and athlete in this research. This result argues that the sponsee-mediated affective communication path that sponsors aim use to communicate with desirable publics is not necessarily a path available to them.

Delirium is a significant problem for older hospitalized people and is associated with poor outcomes. It is poorly recognized and evidence suggests that a major reason is lack of education. Nurses, who are educated about delirium, can play a significant role in improving delirium recognition. This study evaluated the impact of a delirium specific educational website. A cluster randomized controlled trial, with a pretest/post-test time series design, was conducted to measure delirium knowledge (DK) and delirium recognition (DR) over three time-points. Statistically significant differences were found between the intervention and non-intervention group. The intervention groups' DK scores were higher and the change over time results were statistically significant [T3 and T1 (t=3.78 p=<0.001) and T2 and T1 baseline (t=5.83 p=<0.001)]. Statistically significant improvements were also seen for DR when comparing T2 and T1 results (t=2.56 p=0.011) between both groups but not for changes in DR scores between T3 and T1 (t=1.80 p=0.074). Participants rated the website highly on the visual, functional and content elements. This study supports the concept that web-based delirium learning is an effective and satisfying method of information delivery for registered nurses. Future research is required to investigate clinical outcomes as a result of this web-based education.

Objective National guidelines for management of intermediate risk patients with suspected acute coronary syndrome, in whom AMI has been excluded, advocate provocative testing to final risk stratify these patients into low risk (negative testing) or high risk (positive testing suggestive of unstable angina). Adults less than 40 years have a low pretest probability of acute coronary syndrome. The utility of exercise stress testing in young adults with chest pain suspected of acute coronary syndrome who have National Heart Foundation intermediate risk features was evaluated Methods A retrospective analysis of exercise stress testing performed on patients less than 40 years was evaluated. Patients were enrolled on a chest pain pathway and had negative serial ECGs and cardiac biomarkers before exercise stress testing to rule-out acute coronary syndrome. Chart review was completed on patients with positive stress tests. Results The 3987 patients with suspected intermediate risk acute coronary syndrome underwent exercise stress testing. One thousand and twenty-seven (25.8%) were aged less than 40 years (age 33.3 ± 4.8 years). Four of these 1027 patients had a positive exercise stress test (0.4% incidence of positive exercise stress testing). Of those, three patients had subsequent non-invasive functional testing that yielded a negative result. One patient declined further investigations. Assuming this was a true positive exercise stress test, the incidence of true positive exercise stress testing would have been 0.097% (95% confidence interval: 0.079–0.115%) (one of 1027 patients). Conclusions Routine exercise stress testing has limited value in the risk stratification of adults less than 40 years with suspected intermediate risk of acute coronary syndrome

Resumen: En este trabajo se examina el rendimiento de estudiantes universitarios en razonamiento formal con y sin interacción social. La muestra N = 83 estuvo conformada por alumnos provenientes de dos universidades (UNMDP y UAA) quienes fueron asignados a dos condiciones: experimental con interacción (n = 40) y grupo control sin interacción (n = 43). El reactivo empleado consistió en una serie de pruebas del Test de Matrices Progresivas escala general y avanzada. Todos los participantes debieron resolver dichas tareas durante varias semanas: primero en forma individual (pretest), luego en forma colectiva presencial y por chat (díadas, condición experimental) y en forma individual (grupo control), y finalmente en forma individual (postest). Se registraron las interacciones que llevaron a cabo los participantes mediante videofilmación y logs del Chat. El rendimiento fue evaluado según la condición asignada: individual o grupal y en los últimos mediante una evaluación interjueces se estableció la calidad de las interacciones. Los resultados corroboran la superioridad de las díadas por sobre la performance individual; la reiteración en la fase de postest de aquellos ítems incorrectamente resueltos en el pretest más el agregado de nuevos ejercicios pusieron de relieve dos zonas de avance o de internalización de los progresos. En cuanto a la calidad de las interacciones, las mismas son coincidentes. Estos resultados abren nuevos interrogantes acerca del conflicto sociocognitivo y su papel para el avance grupal – individual.

Resumen: La salud mental y el bienestar son fundamentales para nuestra capacidad colectiva y individual como seres humanos de pensar, de exteriorizar los sentimientos, de establecer y mantener relaciones, para estudiar, para perseguir las actividades de ocio, para tomar decisiones diarias y para disfrutar de una vida plena. Una adolescencia saludable es un prerrequisito para una vida adulta saludable. Sin embargo, la realidad actual presenta un panorama preocupante. La formación del capital mental individual y colectivo - especialmente en las primeras etapas de la vida - está siendo retenida por una serie de riesgos evitables para la salud mental (World Health Organization [WHO], 2013). Los adolescentes del sur de Europa (región que ha sido más severamente afectada por la crisis financiera; e.g., Portugal) son señalados como un grupo extremadamente vulnerable, ya que su salud mental fácilmente podría ser influenciada por las dificultades económicas de sus padres y la escasez de solidaridad social (European Parliament, 2012). La promoción de la salud mental de los adolescentes es considerada como una preocupación fundamental (WHO, 2005a, 2013). En este ámbito, las intervenciones centradas en la promoción de la literacía de la salud mental han revelado importantes ventajas en la prevención, reconocimiento, intervención precoz y la reducción del estigma (Pinfold, Stuart, Thornicroft & Arboleda-Florez, 2005; Pinfold, Toulmin, Thornicroft, Huxley, Farmer & Graham, 2003; Schulze, Richter-Werling, Matschinger & Angermeyer, 2003; Stuart, 2006). En consonancia con los marcos de promoción de la salud mentales propuestos por la Organización Mundial de la Salud (2005a), tenemos que involucrar a jóvenes en los ambientes donde interactúan (Burns, 2011). Las escuelas son implícitamente uno de los locales más importantes para la promoción de la salud mental de los adolescentes (Barry, Clarke, Jenkins & Patel, 2013; WHO, 2001). El proyecto “Abrir Espacio para la Salud Mental – Promoción de la salud mental en adolescentes (12-14 años)” tiene como objetivo incrementar literacía de la salud mental en los jóvenes. En el primer año se ha desarrollado un instrumento de evaluación - Mental Health Literacy questionnaire (MHLq) - y la intervención para la promoción de la salud mental. La intervención consiste en 2 sesiones, 90 minutos cada una, implementadas con intervalo de una semana. Siguen una metodología interactiva, utilizando dinámicas de grupo, videos, música y discusión. El estudio de la eficacia de la intervención se lleva a cabo mediante un análisis pre y pos-test con el MHLq, utilizando un grupo experimental y un grupo de control. Este artículo presenta los resultados preliminares de la eficacia de la intervención de promoción de la salud mental en una muestra de 100 adolescentes portugueses (12-14 años). El pos-test mostró un incremento de los niveles de conocimientos de salud mental y estrategias de autoayuda. Los resultados sugieren que la intervención desarrollada parece ser adecuada al objetivo propuesto y refuerzan la creencia de que intervenciones escolares, sistemáticas y sostenibles, para la promoción de la salud mental con jóvenes, es un enfoque prometedor para la promoción de la literacía de la salud mental (Schulze et al., 2003; Rickwood et al., 2005; Corrigan et al., 2007; WHO, 2010).

[EN] The objective of this study was to test the hypothesis that cooperative learning strategies will help to increase nutrition knowledge of nurses and nursing assistants caring for the elderly in different institutional communities of the Basque Country, Spain. The target population was a sample of volunteers, 16 nurses and 28 nursing assistants. Training consisted of 12 nutrition education sessions using cooperative strategies conducted over a period of 3 consecutive weeks. The assessment instruments included two pretest and two posttest questionnaires with questions selected in multiplechoice format. The first questionnaire was about general knowledge of applied nutrition (0-88 point scale) and the second one on geriatric nutrition knowledge (0-18 point scale). Data were analyzed using SPSS vs. 11.0. The outcomes indicated a significant increase in general nutrition knowledge (difference between the pre- and posttest mean score: 14.5±10.1; P<0.001) and in geriatric nutrition knowledge for all participants (difference between the pre- and post-test mean score: 4.6±4.6; P<0.001). So the results indicated that cooperative learning strategies could improve the nutrition knowledge of nursing staff. Additionally, the results of this study provide direction to continuing nutrition education program planners regarding appropriate content and methodology for programs.

Fibromyalgia is a disabling syndrome. Results obtained with different therapies are very limited to date.The goal of this study was to verify whether the application of a mindfulnessbased training program was effective in modifying anger, anxiety, and depression levels in a group of women diagnosed with fibromyalgia. This study is an experimental trial that employed a waiting list control group. Measures were taken at three different times: pretest, posttest, and follow-up. The statistical analyses revealed a significant reduction of anger (trait) levels, internal expression of anger, state anxiety, and depression in the experimental group as compared to the control group, as well as a significant increase in internal control of anger. It can be concluded that the mindfulness-based treatment was effective after 7 weeks. These results were maintained 3 months after the end of the intervention.

O presente estudo analisa as contribuições do uso da música e de pragmatemas na retenção lexical por parte de três turmas de inglês como língua adicional em uma escola estadual na cidade de São João de Meriti (RJ). Para tal, constituiu três condições de pesquisa das quais fizeram parte doze alunos na turma 1 (T1); doze alunos na turma 2 (T2); e nove alunos na turma 3 (T3). A turma 1 (T1) participou de práticas pedagógicas com foco na música e sem foco explícito nos pragmatemas presentes na letra; a turma 2 (T2) de práticas pedagógicas com foco na música e nos pragmatemas da letra; e a turma 3 (T3) de práticas pedagógicas voltadas somente para o ensino-aprendizagem dos pragmatemas presentes na letra, sem o suporte da música. Anteriormente à intervenção, foi aplicado um questionário sobre os hábitos sócio-culturais dos participantes visando conhecer suas preferências musicais e perfil de letramento. Para analisar a relação entre o uso da música e de pragmatemas na retenção lexical, foram aplicados um pré-teste antes da intervenção e dois pós-testes com intervalo de 1 mês entre eles. Além disso, o estudo contou com uma entrevista semi-estruturada com os participantes, visando entender a percepção dos mesmos sobre as práticas utilizadas na intervenção. Os achados apontam que houve uma retenção ligeiramente superior nas condições T2 (música e foco nos pragmatemas) e T3 (foco exclusivo nos pragmatemas), com ligeira superioridade para a condição 3. O pragmatema recuperado com maior frequência foi "What's up", fato que pode ser parcialmente explicado pelo fato de ser pronunciado como uma palavra só e pelo número de letras que o representa ortograficamente. Estudos futuros poderão esclarecer se há significância estatística entre as diferenças encontradas assim como melhor explorar como o ensino explícito de unidades lexicais complexas pode contribuir para a retenção desses itens lexicais e consequentemente para o ensino-aprendizagem de línguas adicionais. A intervenção permitiu que os aprendizes passassem a entender que as palavras não ocorrem de modo isolado, mas que sempre caminham junto a outras. Permitiu também que a rotina pedagógica contemplasse a coconstrução do conhecimento, levando os aprendizes a reagir positivamente às práticas utilizadas no ensino de inglês, conforme relatos durante as entrevistas semi-estruturadas. Isso per se já justifica a utilização de práticas semelhantes e ilustra a contribuição do presente estudo
