Riders in the storm: the professions and healthcare governance

The public sector is facing turbulent times and this also challenges the health professions who are expected to serve both the interests of the citizens and the cost-containment and austerity policies of governments. This article seeks to explore the changing role of the health professions. I introduce an approach on ���citizen professionals��� as active players in the policy process and mediators between the state/policymakers and the citizens/patients. The aim is to highlight a transformative potential of professionalism and the connectedness with other sets of governance, like management. Empirical material from a German case study and a comparative European study serve to illustrate the arguments, drawing on policy analysis and secondary sources. The results bring the complexity of transformations and new emergent forms of professionalism into view that cannot be understood in traditional categories of conflict, exclusion and jurisdiction. Exploring the potential of the health professions to creatively respond to new challenges may reveal new opportunities for innovating healthcare policy beyond market and management.

On the development of textual competence in primary education

The aim of this article is to present the results of an action research project, which has been put into practice in Primary Education. This project was intended to develop students��� textual competence, considering both comprehension and textual production. Our starting hypothesis was that teaching the schematisation of text types, focusing on linguistic devices that underlie text production, would promote the development of textual competence, leading to the production of more coherent and cohesive texts. In order to test this hypothesis we implemented the project in three phases. First, before the intervention, we collected texts produced by the students. Secondly, we implemented a didactic program designed to develop students��� textual competence. Lastly, after the intervention, we collected students��� texts once again. Data was analyzed according to categories that confer cohesion and coherence to different types of texts. Narrative, descriptive, and explanatory texts were assessed in terms of 1) building an autonomous text; 2) hierarchisation of information, and 3) textual organisation. Overall, results indicate that students developed their text conceptualisations, their understanding of the different structures of texts, and produced better writing. Indeed, their written work shows a marked progression from the beginning of the intervention program to the end of the program.

Obesity and gestational weight gain: cesarean delivery and labor complications

OBJECTIVE: To assess the association between pre-gestational obesity and weight gain with cesarean delivery and labor complications. METHODS: A total of 4,486 women 20-28 weeks pregnant attending general prenatal care clinics of the national health system in Brazil from 1991 to 1995 were enrolled and followed up through birth. Body mass index categories based on prepregnancy weight and total weight gain were calculated. Associations between body mass index categories and labor complications were adjusted through logistic regression analysis. RESULTS: Obesity was present in 308 (6.9%) patients. Cesarean delivery was performed in 164 (53.2%) obese, 407 (43.1%) pre-obese, 1,045 (35.1%) normal weight and 64 (24.5%) underweight women. The relative risk for cesarean delivery in obese women was 1.8 (95% CI: 1.5-2.0) compared to normal weight women. Greater weight gain was particularly associated with cesarean among the obese (RR 4th vs 2nd weight gain quartile 2.2; 95% CI: 1.4-3.2). Increased weight at the beginning of pregnancy was associated with a significantly higher adjusted risk of meconium with vaginal delivery and perinatal death and infection in women submitted to cesarean section. Similarly, greater weight gain during pregnancy increased the risk for meconium and hemorrhage in women submitted to vaginal delivery and for prematurity with cesarean. CONCLUSIONS: Pre-gestational obesity and greater weight gain independently increase the risk of cesarean delivery, as well as of several adverse outcomes with vaginal delivery. These findings provide further evidence of the negative effects of prepregnancy obesity and greater gestational weight gain on pregnancy outcomes.

Motivations which influence volunteers' satisfaction

In this paper we attempt to find out which motivations influence volunteers satisfaction. So, in a first moment, we categorize satisfaction through a factor analysis and then use linear regression models to find out the relations previously mentioned. Furthermore we analyse the existence of correlations between some demographic attributes and the other variables. In this research the population under study includes volunteers that work in the health area, more precisely volunteers that work in hospital and have direct contact with patients and their families. We obtained a total of 327 questionnaires and after excluding incomplete answers we get 304 questionnaires which embody a response rate of 36%. The outcomes of our analysis reveal that we can categorize satisfaction into intrinsic and extrinsic categories and show that motivations related to belonging and protection and career recognition are the ones influencing extrinsic satisfaction; motivations associated to development and learning and altruism are the ones with higher effect in intrinsic satisfaction. There are some negative correlations between age and extrinsic satisfaction, between years of participation and extrinsic satisfaction, between education and the motivation related to belonging and protection and between age and the motivation related to career recognition. There is only one positive correlation between hours per week and intrinsic satisfaction. The results offer new insights for research about volunteers��� motivations, motive fulfillment and volunteer satisfaction. Furthermore the outcomes advocate that to ensure satisfied volunteers, their motivations must be identified in a timely and appropriate moment, meaning that should happened as early as possible.

Motivations in volunteer work

The objective of this paper is to review and discuss the literature about volunteers��� motivations to donate their time to NGOs (Non Governmental Organisations). According to Parboteeah, Cullenb & Lim (2004) management research has not paid much attention to voluntarism, however, voluntarism is a substantial part of productive work for many societies. Wilson & Pimm (1996) show that in Great Britain about 39% of the adult population has been involved in some volunteer activity for some period of time. In the U.S.A. these values reach 50% (Wilson & Pimm, 1996). Considering the benefits that voluntarism can bring to an organisation, we understand that more attention must be devoted to this phenomenon. The more an organisation knows volunteers, the better this organisation will be able to meet the needs and expectations of these individuals. We present a literature review that illustrates and compares the different motivations associated with volunteer work. The paper includes a bibliographical databases search in specialised journals. The search used the key words ���motivations��� and ���voluntarism��� (in the heading and text body) and covered all numbers between 2000 and 2007. We identify the existence of repeated motivations (Holmberg & S��derlung, 2005; Prouteau & Wolff, 2008; Soupourmas & Ironmonger, 2001; Yavas & Riecken, 1997), which allow the establishment of a typology of volunteers��� motivations, based on four categories: altruism, social needs, self-esteem, learning and self-development. Finally we identify three main gaps in the literature that justify further research. First, research focusing on the differences between motivations related to volunteers��� "Attraction" versus "Retention" in NGO���s is nil. Second, the great majority of the studies rely on north American (USA and Canada) and Australian context, which demands for further research in European countries. Third, the majority of NGOs researched are related to sport, art or the environment, and it would be interesting to explore the relationship between motivation and NGO type. These questions may obtain interesting answers for NGO management, in particular with regard to volunteer attraction and retention.

Motivation among Hospital volunteers: an empirical analysis in Portugal

The purpose of this paper is to identify the different types of motivations in hospital volunteers. We present a literature review about different types of motivation and we collect data from hospital volunteers through a questionnaire. Four different motivation categories are identified: development and learning, altruism, career recognition and belonging and protection. The main motivations expressed are development and learning, followed by altruism. Belonging and protection, followed by career recognition are the least cited motivations. Career recognition is negatively correlated with age, and belonging/ protection is negatively correlated with education. That is, younger volunteers present more career recognition motives and less educated volunteers have more from protection and belonging. This study encompasses hospital volunteers and their motivations. The paper is useful to policy makers aiming to develop targeted approaches to attracting and retaining volunteers.

O uso do smartphone na avalia����o do risco de queda associado ao envelhecimento

Introdu����o: O decl��nio do equil��brio, da for��a dos membros inferiores e o medo de cair s��o fatores de risco de queda associados ao envelhecimento e a sua avalia����o pode ser realizada pelo teste One Leg Standing (OLS), Sit to Stand (STS) e pela Falls Eficacy Scale (FES), respetivamente. As aplica����es para smartphone constituem uma alternativa para a avalia����o dos fatores de risco de queda no envelhecimento. Objetivo: Analisar a capacidade de uma aplica����o para smartphone na avalia����o dos testes STS, OLS e FES. Metodologia: Realizou-se um estudo anal��tico numa amostra de 27 volunt��rios com idade ��� 60 anos. Realizaram-se os testes STS, OLS e a FES (vers��o iconogr��fica, apresentada no smartphone). Os dados foram recolhidos simultaneamente por um smartphone e pelo Qualisys Motion Capture Systems associado a uma plataforma de for��as. Foi utilizado o r de Pearson ou Spearman para analisar as poss��veis correla����es. Resultados: No STS obteve-se uma correla����o muito forte (rp=0.97) no n��mero de repeti����es de ciclos Sit Stand Sit (SLS) e forte na dura����o m��dia do SLS (rp=0.85) e das subfases Sit to Stand (rp=0.69) e Stand to Sit (rp=0.778), com p<0.001. As medidas de inclina����o do tronco apresentaram correla����es fortes, com exce����o do ��ngulo inicial (p���0.05). No OLS, verificou-se uma correla����o moderada entre o deslocamento do centro de press��o peak to peak m��dio-lateral (rs=0.45; p=0.017) e antero-posterior (rs=0.39; p=0.046), root mean square m��dio-lateral (rs=0.39; p=0.046) e antero-posterior (rs=0.46; p=0.017) e ��rea do estatocinesiograma (rs=0.45; p=0.018). Na FES obteve-se uma correla����o moderada em tr��s categorias: ���tomar banho/duche��� (rs=0.49; p=0.010), ���deitar/levantar da cama (rs=0.43; p=0.024) e ���chegar aos arm��rios��� (rs=0.38; p=0.050). Conclus��o: A aplica����o para smartphone parece avaliar corretamente os ciclos e a varia����o da inclina����o do tronco no STS, por��m parece necessitar de ser reajustada na FES e na velocidade do deslocamento do centro de press��o, no OLS.
