The present study builds on a previous proposal for assigning probabilities to the outcomes computed using different primary indicators in single-case studies. These probabilities are obtained comparing the outcome to previously tabulated reference values and reflect the likelihood of the results in case there was no intervention effect. The current study explores how well different metrics are translated into p values in the context of simulation data. Furthermore, two published multiple baseline data sets are used to illustrate how well the probabilities could reflect the intervention effectiveness as assessed by the original authors. Finally, the importance of which primary indicator is used in each data set to be integrated is explored; two ways of combining probabilities are used: a weighted average and a binomial test. The results indicate that the translation into p values works well for the two nonoverlap procedures, with the results for the regression-based procedure diverging due to some undesirable features of its performance. These p values, both when taken individually and when combined, were well-aligned with the effectiveness for the real-life data. The results suggest that assigning probabilities can be useful for translating the primary measure into the same metric, using these probabilities as additional evidence on the importance of behavioral change, complementing visual analysis and professional's judgments.

À partir des années 1980, la théorisation de la promotion de la santé et sa mise en place font partie de l’agenda des organisations internationales de santé et de plusieurs gouvernements. Cependant, une certaine tension est observable dans la compréhension de la promotion de la santé, et ce, dès ses débuts. En effet, elle est conçue en général selon une approche comportementale comme stratégie pour le changement de comportements individuels ou collectifs qui met l’accent sur les facteurs de risque et très peu fréquemment conçue selon une approche structurelle, incluant une action sur les déterminants structurels des sociétés responsables de l’état de santé des populations dans une mesure plus importante que les systèmes de soins. Cette recherche qualitative –étude de cas multiples- menée en Argentine et au Brésil, vise à analyser la place et la compréhension de la promotion de la santé dans les politiques nationales de santé de deux pays à travers l’analyse du processus d’élaboration des politiques publiques. Nous viserons à distinguer la promotion de la santé en tant que comportementale ou structurelle et à expliquer les raisons pour lesquelles elle est comprise de telle ou telle autre façon. Finalement, nous essayerons d’identifier les opportunités pour qu’une approche structurelle de la promotion de la santé soit adoptée dans la politique nationale de santé. Les données analysées proviennent d’entrevues semi-structurées (n=28) et de documents divers : sites gouvernementaux sur Internet, documents remis par les interviewés, documents officiels, soit gouvernementaux, soit des organismes de coopération et de financement. Notre cadre conceptuel s’est inspiré des trois modèles : celui du changement des politiques publiques de Sabatier et Jenkins-Smith (1999 ; 2009), celui des courants politiques de Kingdon (1984) et le cadre conceptuel proposé par Walt (1994) pour l’analyse du rôle des organisations internationales. Nous avons identifié deux niveaux d’analyse : l’organisation de l’État et le sous-système de santé. Nous avons aussi tenu compte de l’influence des événements externes et des organisations internationales de coopération technique et de financement. Notre démarche vise à observer, à analyser et à comprendre la façon dont ces niveaux influencent la place et la compréhension de la promotion de la santé dans la politique nationale de santé. La perspective temporelle de plus de douze années nous a permis de mener une analyse sur plusieurs années et de mieux comprendre le changement de la politique de santé à différents moments de son histoire ainsi que l’identification des acteurs et des coalitions les plus importants depuis l’origine des champs de la santé publique dans les deux pays. Les résultats de notre analyse montrent que la promotion de la santé – conçue selon une approche structurelle – ne fait pas encore partie du courant principal de la politique nationale de santé dans aucun des deux pays. Cependant, les explications diffèrent : En Argentine, on observe un sous-système de santé fragmenté avec prédominance du modèle médical ; les actions menées renforcent ce fonctionnement en ne permettant pas la discussion à propos des valeurs sous-jacentes à l’organisation du système de santé ni sur son changement en fonction des besoins de santé du pays. Au Brésil, la réforme sanitaire questionne le modèle préexistant et arrive à instaurer la santé comme droit au niveau de l’État. L’accent mis sur l’organisation des services réduit la compréhension de la promotion de la santé à une « politique nationale de promotion de la santé » qui vise le changement des comportements. L’analyse du rôle des organisations internationales montre deux situations différentes dans les deux pays : pour l’Argentine, il existe une dépendance majeure autant à l’agenda qu’au financement de ces organisations. Le manque d’un agenda national en matière de promotion de la santé fait que le pays adopte l’agenda international avec très peu des questionnements. Dans le cas du Brésil, la situation est bien différente et on observe une capacité importante à négocier avec la coopération internationale. Cela se fait aussi avec un intérêt du pays pour l’adoption de l’agenda des organisations internationales dans le but d’une reconnaissance et de sa participation à des instances internationales. Alors, pour des raisons différentes, les deux pays adoptent l’agenda international de la promotion de la santé avec une approche comportementale. À partir de notre recherche, nous considérons que cinq réflexions doivent guider l’analyse de la promotion de la santé en Amérique latine : 1) Les processus de réforme de l’État des années 1990 et ses conséquences actuelles (type de réforme, valeurs sociétales, arrangements constitutionnels) ; 2) Les processus de réforme des systèmes de santé avec un regard sur la composante de décentralisation (réforme sanitaire ou administrative ?, quel modèle prédomine dans le champ de la santé publique ?) ; 3) La revalorisation des soins primaires de santé de la fin des années 1990 (quel impact dans le pays ?) ; 4) La tendance à la réduction des propositions élargies autant des politiques que des programmes ; et 5) Les défis actuels des systèmes de santé (travailler avec d’autres secteurs pour produire de la santé, pour incorporer et pour mieux maîtriser les déterminants sociaux et structuraux de santé). Les résultats de notre analyse nous permettent d’identifier l’importance du rôle du gouvernement national par rapport au développement et à la compréhension de la promotion de la santé. De plus, cette recherche montre que même s’il existe une influence du contexte et de l’idéologie du gouvernement sur la compréhension de la promotion et l’inclusion des déterminants sociaux de santé, c’est l’organisation de l’État avec ces valeurs de base qui sera déterminante dans la création des conditions pour le développement d’une promotion de la santé structurelle. Alors que la littérature sur la promotion de la santé accorde encore très peu de place au rôle du niveau national et de l’État dans son développement, il est clair que ces derniers ont un impact fondamental sur la place de la promotion de la santé dans la politique et sur la façon de la comprendre et de la mettre en place. Les théories utilisées pour cette recherche nous ont aidée à modéliser notre cadre conceptuel et à mener une démarche d’analyse des politiques publiques. Cette démarche permet d’améliorer les connaissances sur le changement de la politique nationale de santé par rapport à la promotion de la santé en tenant compte des dynamiques gouvernementales, champ peu exploré encore. Ce cadre conceptuel, à la fois souple et rigoureux, pourrait s’avérer approprié pour mener d’autres recherches similaires portant sur la place et la compréhension de la promotion de la santé dans les politiques nationales de santé dans d’autres pays de l’Amérique latine.

The misuse of personal protective equipment (PPE) during pesticide application was investigated among smallholders in Colombia. The integrative agent-centered (IAC) framework and a logistic regression approach were adopted. The results suggest that the descriptive social norm was significantly influencing PPE use. The following were also important: (1) having experienced pesticide-related health problems; (2) age; (3) the share of pesticide application carried out; and (4) the perception of PPE hindering work. Interestingly, the influence of these factors differed for different pieces of PPE. Since conformity to the social norm is a source of rigidity in the system, behavioral change may take the form of a discontinuous transition. In conclusion, five suggestions for triggering a transition towards more sustainable PPE use are formulated: (1) diversifying targets/tools; (2) addressing structural aspects; (3) sustaining interventions in the long-term; (4) targeting farmers’ learning-by-experience; and (5) targeting PPE use on a collective level.

This review provides a classification of public policies to promote healthier eating as well as a structured mapping of existing measures in Europe. Complete coverage of alternative policy types was ensured by complementing the review with a selection of major interventions from outside Europe. Under the auspices of the Seventh Framework Programme's Eatwell Project, funded by the European Commission, researchers from five countries reviewed a representative selection of policy actions based on scientific papers, policy documents, grey literature, government websites, other policy reviews, and interviews with policy-makers. This work resulted in a list of 129 policy interventions, 121 of which were in Europe. For each type of policy, a critical review of its effectiveness was conducted, based on the evidence currently available. The results of this review indicate a need exists for a more systematic and accurate evaluation of government-level interventions as well as for a stronger focus on actual behavioral change rather than changes in attitude or intentions alone. The currently available evidence is very heterogeneous across policy types and is often incomplete.

ABSTRACTThe general aim of this thesis was to investigate behavioral change communication at nurse-led chronic obstructive pulmonary disease (COPD) clinics in primary health care, focusing on communication in self-management and smoking cessation for patients with COPD.Designs: Observational, prospective observational and experimental designs were used.Methods: To explore and describe the structure and content of self-management education and smoking cessation communication, consultations between patients (n=30) and nurses (n=7) were videotaped and analyzed with three instruments: Consulting Map (CM), the Motivational Interviewing Treatment Integrity (MITI) scale and the Client Language Assessment in Motivational Interviewing (CLAMI). To examine the effects of structured self-management education, patients with COPD (n=52) were randomized in an intervention and a control group. Patients’ quality of life (QoL), knowledge about COPD and smoking cessation were examined with a questionnaire on knowledge about COPD and smoking habits and with St. George’s Respiratory Questionnaire, addressing QoL. Results: The findings from the videotaped consultations showed that communication about the reasons for consultation mainly concerned medical and physical problems and (to a certain extent) patients´ perceptions. Two consultations ended with shared understanding, but none of the patients received an individual treatment-plan. In the smoking cessation communication the nurses did only to a small extent evoke patients’ reasons for change, fostered collaboration and supported patients’ autonomy. The nurses provided a lot of information (42%), asked closed (21%) rather than open questions (3%), made simpler (14%) rather than complex (2%) reflections and used MI non-adherent (16%) rather than MI-adherent (5%) behavior. Most of the patients’ utterances in the communication were neutral either toward or away from smoking cessation (59%), utterances about reason (desire, ability and need) were 40%, taking steps 1% and commitment to stop smoking 0%. The number of patients who stopped smoking, and patients’ knowledge about the disease and their QoL, was increased by structured self-management education and smoking cessation in collaboration between the patient, nurse and physician and, when necessary, a physiotherapist, a dietician, an occupational therapist and/or a medical social worker.Conclusion The communication at nurse-led COPD clinics rarely involved the patients in shared understanding and responsibility and concerned patients’ fears, worries and problems only to a limited extent. The results also showed that nurses had difficulties in attaining proficiency in behavioral change communication. Structured self-management education showed positive effects on patients’ perceived QoL, on the number of patients who quit smoking and on patients’ knowledge about COPD.

Esta obra tem como tema central a abordagem da política nacional de conciliação implementada pelo Conselho Nacional de Justiça, bem como a sua adoção pelo TJRS. Em razão da mudança comportamental da sociedade nas últimas décadas, decorrente de vários fatores, entre eles: a evolução do Estado liberal para o Estado democrático de direito, a constitucionalização dos direitos fundamentais e o acesso à justiça, entre outros, ocorreu o aumento da demanda judicial, gerando problemas na prestação jurisdicional, como morosidade do sistema e difícil acesso ao Poder Judiciário. Assim, no auge da crise do Poder Judiciário, através da emenda constitucional nº 45, foi criado o Conselho Nacional de Justiça, com o objetivo de tornar a prestação jurisdicional, de forma moral, eficiente e efetiva. O Conselho Nacional de Justiça, como integrante do Poder Judiciário, visando, através de uma política pública nacional, a maximizar a prestação jurisdicional e oferecer uma justiça mais célere e justa, através da resolução número 125, determinou a implantação da política Nacional da Conciliação. Desse modo, o Poder Judiciário, utilizando os métodos alternativos de solução de conflitos, a conciliação e a mediação, espera oferecer uma jurisdição mais rápida, contribuir para a pacificação social e diminuir o número de ações judiciais, com a implementação da política Nacional da Conciliação. O Tribunal de Justiça gaúcho, visando a cumprir as determinações da Resolução n. 125 do Conselho Nacional de Justiça, instalou no Estado do Rio Grande do Sul quatro centrais de conciliação e mediação, entre elas a Central Judicial de Conciliação e Mediação da comarca de Pelotas. Os resultados apresentados por esse órgão demonstram que as conciliações, embora não apresentem um número expressivo, têm se revelado um mecanismo célere e eficaz, na busca da resolução de conflitos e pacificação social.

O objetivo deste trabalho é avaliar se houve evolução nas práticas de governança corporativa entre os anos de 2005 a 2012 nas empresas brasileiras que abriram capital entre 2004 e 2006, e se esta evolução ocorreu no sentido de melhoria das práticas de governança. Busca-se também entender se esta evolução ocorreu continuamente em todo o período estudado ou se somente nos primeiros anos após seu IPO. Também busca-se compreender se a evolução ocorreu somente nos requisitos mandatórios por lei ou se houve uma real mudança de cultura nas empresas após abrirem seu capital. Para mensurar a qualidade das práticas de governança foi utilizado o Corporate Governance Index – CGI desenvolvido por Leal e Carvalhal-da-Silva (2007) para avaliar as práticas de governança em empresas brasileiras. O índice é composto de 24 questões binárias, e considera-se uma evolução nas práticas quanto mais o índice da empresa se aproxima dos 24 pontos. O índice foi calculado ano a ano para o período e empresas estudadas. Em seguida, o índice foi dividido em duas partes, questões diretamente relacionadas a leis e regulamentações e questões não diretamente relacionadas a leis e regulamentações. Utilizando os testes estatísticos T-student e W de Kendall, comprovou-se estatisticamente que houve evolução nas práticas de governança corporativa entre os anos de 2005 a 2012, entretanto, prova-se estatisticamente que esta melhora está concentrada no período de 2005 a 2008, sendo que não foi constatada uma alteração significativa nas práticas no período de 2009 a 2012. Identificou-se também que houve uma evolução positiva nas práticas de governança não diretamente relacionadas a leis e regulamentações entre os anos de 2005 a 2012, entretanto, quando retira-se deste teste as questões que foram indiretamente impactadas por mudanças nas instruções da CVM que ocorreram no período, encontra-se uma piora nas práticas de governança entre 2005 e 2012. Estes resultados sugerem que as empresas estão trabalhando em um movimento de “check the box” das boas práticas de governança, cumprindo o que é mandatório por lei e regulamentações, e questiona se as evoluções de leis, regulamentações e códigos de boas práticas de governança corporativa no Brasil estão cumprindo o seu objetivo final de desenvolver uma cultura de boa governança nas empresas brasileiras.

In recent years, the Brazilian construction industry has gone by changes like currency stability, increasing competition, shortage of skilled labor and increasing quality importance required by the customer, who made the sector companies seek solutions through new management practices in order to become more efficient. A alternative to these management practices is known as Lean Construction which is derived from the Toyota System Production. Lean Construction main goals are to reduce parts of activities that do not add value, increase product value by considering customer needs, reduce variability and production cycle time, simplify process by reducing the number of parts or steps, increase the flexibility in the product execution and transparency process, focus the control on overall process, introduce continuous improvement process, maintain a balance between improvements in flows and conversions and seek to learn from practices adopted by competitors. However, the construction industry is characterized by having nomadic activity, which undertakes an unique product with high cost of production and big inertia for behavioral change, making it difficult to implement the philosophy of lean construction in companies. In this sense, the main objective of this study is to develop a methodology for implementation of the principles of Lean Construction. The method of implementing the proposed management system was designed with the aid of 5W2H tool, and the implementation process is divided into three phases. The first one aims to know in a macro way the current operation of construction, identify who is its target audience and what are the products and services offered to the Market. The second phase aims to describe what actions should be taken and which documents are needed to be created or modified; finally, the third step goal consists in how to control and monitor established processes, where through Strategic Planning the company goals would be set along with their respective targets and indicators in order to keep the system working, aiming for continuous improvement with focus on the customer. This methodology was conceived as a case study analyzing a medium size construction with more than 18 years of activity and certified for almost 10 years with ISO9001 and level A in PBQP-H. We also conclude that this implementation process can be used in any developer and / or builder

We have recently suggested that the elevated T-maze (ETM) is not a useful test to study different types of anxiety in mice if a procedure similar to that originally validated for rats is employed. The present study investigated whether procedural (five exposures in the enclosed arm instead of three as originally described for rats) and structural (transparent walls instead of opaque walls) changes to the ETM leads to consistent inhibitory avoidance acquisition (IAA) and low escape latencies in mice. Results showed that five exposures to the ETM provoked consistent IAA, an effect that was independent of the ETM used. However, the ETM with transparent walls (ETMt) seemed to be more suitable for the study of conditioned anxiety (i.e. IAA) and unconditioned fear (escape) in mice, since IAA (low baseline latency with a gradual increase over subsequent exposures) and escape (low latency) profiles rendered it sensitive to the effects of anxiolytic and anxiogenic drugs. In addition to evaluation of drug effects on IAA and escape, the number of line crossings in the apparatus were used to control for locomotor changes. Results showed that whereas diazepam (1.0-2.0 mg/kg) and flumazenil (10-30 mg/kg) impaired IAA, FG 7142 (10-30 mg/kg) did not provoke any behavioral change. Significantly, none of these benzodiazepine (BDZ) receptor ligands modified escape latencies. The 5-HT1A partial receptor agonist buspirone (1.0-2.0 mg/kg) and the 5-HT releaser fenfluramine (0.15-0.30 mg/kg) impaired IAA and facilitated escape, while the full 5-HT1A receptor agonist, 8-OH-DPAT (0.05-0.1 mg/kg) and the 5-HT2B/2C receptor antagonist, SER 082 (0.5-2.0 mg/kg) failed to modify either response. mCPP (0.5-2.0 mg/kg), a 5-HT2B/2C receptor agonist, facilitated IAA but did not alter escape latency. Neither antidepressant utilized in the current study, imipramine (1.0-5.0 mg/kg) and moclobemide (3.0-10 mg/kg) affected IAA or escape performance in mice. The well-known anxiogenic drugs yohimbine (2.0-8.0 mg/kg) and caffeine (10-30 mg/kg) did not selectively affect IAA, although caffeine did impair escape latencies. Present results suggest the ETMt is useful for the study of conditioned anxiety in mice. However, upon proximal threats (e.g. open arm exposure), mice do not exhibit escape behavior as an immediate defensive strategy, suggesting that latency to leave open arm is not a useful parameter to evaluate unconditioned fear in this species.

A literatura tem sugerido que regras podem gerar padrões de respostas mais resistentes a mudanças ocorridas nas contingências de reforço, e que o grau de resistência à mudança depende da força da relação estabelecida entre o estímulo antecedente e a conseqüência por ele produzida. O presente estudo testou se uma história experimental de enfraquecimento ou fortalecimento da relação regra / conseqüências programadas, diminuiria a resistência a mudança do operante seguir regras quando este fosse posto em extinção. Dez estudantes universitários foram expostos a um procedimento de escolha segundo o modelo. Em cada tentativa, um estímulo modelo e três de comparação (arranjo de estímulos) eram apresentados ao participante, que deveria apontar para os três de comparação, em seqüência. Cada estímulo de comparação possuía apenas uma dimensão (cor, espessura ou forma) em comum com o modelo e diferia nas demais. O experimento foi constituído de duas condições compostas de seis fases que diferiam quanto a ordem de apresentação dos graus de correspondência regras/contingências. A Fase 1 de ambas as condições era iniciada com instruções mínimas e objetivou identificar preferências do participante por alguma seqüência em particular. A Fase 2 de ambas as condições era iniciada com a apresentação de instruções discrepantes das contingências. Na Condição 1 as Fases 3, 4 e 5 eram iniciadas com instruções que variaram os graus de correspondência com as contingências programadas em 100%, 50%, e 0%, respectivamente. Na condição 2 as Fases 3, 4 e 5 variaram os graus de correspondência com as contingências programadas em 0%, 50%, e 100%, respectivamente. A Fase 6 de ambas as condições era iniciada com a apresentação de instruções discrepantes das contingências. As respostas dos participantes eram reforçadas com pontos trocáveis por dinheiro em esquema de reforçamento contínuo. Todos os participantes seguiram instruções em todas as fases experimentais das duas condições. Estes resultados sugerem que a manipulação nos graus de correspondência regras/contingências programadas não foi condição suficiente para produzir mudanças comportamentais, ou seja, não foi suficiente para tornar a discrepância regras/contingências mais discriminável, levando ao abandono do seguir regra.
