Como anda a comunica????o p??blica?

A necessidade de descentraliza????o e de transpar??ncia dos procedimentos e decis??es governamentais e dos pactos de interesse coletivo levou, na Fran??a, ao desenvolvimento da comunica????o p??blica, a partir de 1989. Esse tipo de comunica????o deve ultrapassar os objetivos restritos do marketing de vendas das empresas privadas, no qual se inspira para ser a fonte de informa????o segura para o cidad??o. No entanto, esse ?? um desafio cotidiano, pois a comunica????o p??blica n??o pode ser confundida com a autopromo????o do pol??tico. Para isso, ?? fundamental desenvolver habilidades de comunica????o para os servidores p??blicos de modo que suas orienta????es para o cidad??o sejam claras, acuradas, ??ticas e justas.

The coexistence of peace and conflict in South America: toward a new conceptualization of types of peace

South America's predominant democratic regimes and its increasing interdependence on regional trade have not precluded the emergence of militarized crises between Colombia and Venezuela or the revival of boundary claims between Chile and Peru. This way, how can we characterize a zone that, in spite of its flourishing democracy and dense economic ties, remain involved in territorial disputes for whose resolution the use of force has not yet been discarded? This article contends that existing classifications of zones of peace are not adequate to explain this unusual coexistence. Thus, its main purpose is to develop a new analytical category of regional peace for assessing this phenomenon: the hybrid peace. It aims to research the evolution of security systems in South America during the previous century and build a new, threefold classification of peace zones: negative peace zones, hybrid peace zones, and positive peace zones.

The influence of matrix mediated hopping conductivity, filler concentration, aspect ratio and orientation on the electrical response of carbon nanotube/polymer nanocomposites

A model to simulate the conductivity of carbon nanotube/polymer nanocomposites is presented. The proposed model is based on hopping between the fillers. A parameter related to the influence of the matrix in the overall composite conductivity is defined. It is demonstrated that increasing the aspect ratio of the fillers will increase the conductivity. Finally, it is demonstrated that the alignment of the filler rods parallel to the measurement direction results in higher conductivity values, in agreement with results from recent experimental work.

Effect of fiber orientation in gelled poly (vinylience fluoride) electrospun membranes for Li-ion battery applications

Battery separators based on electrospun membranes of poly(vinylidene fluoride) (PVDF) have been prepared in order to study the effect of fiber alignment on the performance and characteristics of the membrane. The prepared membranes show an average fiber diameter of ~272 nm and a degree of porosity of ~87 %. The gel polymer electrolytes are prepared by soaking the membranes in the electrolyte solution. The alignment of the fibers improves the mechanical properties for the electrospun membranes. Further, the microstructure of the membrane also plays an important role in the ionic conductivity, being higher for the random electrospun membrane due to the lower tortuosity value. Independently of the microstructure, both membranes show good electrochemical stability up to 5.0 V versus Li/Li+. These results show that electrospun membranes based on PVDF are appropriate for battery separators in lithium-ion battery applications, the random membranes showing a better overall performance.

A coesão de grupo dentro de uma organização

RESUMO: Na organização do tecido empresarial a sociedade contemporânea alcança o seu sucesso mediante a Coesão do Grupo. A Coesão de Grupo é hoje decisiva para qualquer organização. Um grupo começa quando as pessoas se juntam pelo desejo de pertencer a esse mesmo grupo, para ajudar e contribuir para o bem-estar dessa própria equipa. A Coesão no seio do Grupo é fundamental para se alcançarem resultados positivos. Para Weinberg e Gould (2001) “a Coesão relacionada à tarefa reflecte o grau em que os membros de um grupo trabalham juntos para alcançar objectivos comuns”. A Coesão interna aumenta se a equipa trabalha em busca dos mesmos objectivos com uma entrega total e absoluta em todo o trabalho que realizam. Quanto maior a cordialidade e a confiança transmitida e criada no meio do grupo, consequentemente maior será a Coesão e a produtividade da equipa. Com a Coesão de Grupo existe uma relação de interdependência, em termos de trabalho, nos elementos do grupo. O modelo de Coesão de Grupo acentua as semelhanças entre cada elemento e oferece também a oportunidade de participarem em todas as decisões. A Coesão de Grupo permite ainda que os membros permaneçam juntos, que os membros confiem e sejam leais uns aos outros e que também se sintam seguros. Torna-se determinante frisar que a Coesão permite que os membros se tornem influenciados pelo grupo em si, o que aumenta significativamente a satisfação dos seus membros e, à medida que o trabalho se desenvolve, que a interacção entre os membros do grupo se intensifique. Só assim se consegue provocar, manter e consolidar a Coesão dentro da organização. ABSTRACT: In the organization of business, the contemporary society achieves its success through group cohesion. The Group Cohesion is very important today, for any organization. A group begins when people come together by the desire to belong, to help and contribute to the welfare of own team. The Cohesion within a team is central to achieving positive results. To Weinberg and Gould (2001) “related to task Cohesion reflects the degree to which the group members work together to achieve common goals”. The Cohesion within the Group increases if the team works toward the same objectives, with a total and absolute in all the work they do. The greater the friendship and trust created and transmitted through the group, consequent greater Cohesion and team productivity. With the Group Cohesion there is a relationship of interdependence, in terms of labor among group members. With the group cohesion there is something similar between the group members and also the opportunity to participate in all decisions. The Cohesion of the Group allows members to stay together, that the members trust and be loyal to each other and also feel safe. I can only stress that Cohesion allows members to become influenced by the group itself, which increases the signification and satisfaction of its members, as the work develops, and that the interaction between group members to intensify. Only thus could lead to, maintain and strengthen the Cohesion within the organization.

The study of public administration in India, the Philippines, Canada and Australia: the universal struggle against epistemic colonization, and toward critical assimilation

The study of public administration has been characterized as a strong international focus, as both governments and scholars have sought to learn from the experience of other societies. While in a perfect world, one would expect a sort of pragmatic universalism, instead, many scholars tend to bring lessons from one country, or from a single cultural reality. This modest contribution lies in showing a series of national experiences rarely brought to the discourse about public administration in Brazil: Canada, Australia, India and the Philippines. Special emphasis will be given to the following: the origins and the development of public administration; the influence of ideology; and the complex tension between global theory and local practices.

Validation of a measurement scale for the relationship between the orientation to corporate social responsibility and other business strategic variables

The importance of Social Responsibility (SR) is higher if this business variable is related with other ones of strategic nature in business activity (competitive success that the company achieved, performance that the firms develop and innovations that they carries out). The hypothesis is that organizations that focus on SR are those who get higher outputs and innovate more, achieving greater competitive success. A scale for measuring the orientation to SR has defined in order to determine the degree of relationship between above elements. This instrument is original because previous scales do not exist in the literature which could measure, on the one hand, the three classics sub-constructs theoretically accepted that SR is made up and, on the other hand, the relationship between SR and the other variables. As a result of causal relationships analysis we conclude with a scale of 21 indicators, validated scale with a sample of firms belonging to the Autonomous Community of Extremadura and it is the first empirical validation of these dimensions we know so far, in this context.

Dispositional optimism is unidimensional or bidimensional? The Portuguese Revised Life Orientation Test

The aim of the study is to adapt and then discuss the appropriateness of the Life Orientation Test as a one or two dimension scale. The research includes two studies; one is composed of a sequential sample of 280 people with multiple sclerosis, 71% female, and another includes a convenience sample of 615 individuals from the community, 51.1% female. Because the construct is built upon a theoretical assumption that has one dimension, we examine the hypothesis of one or two factor solutions through confirmatory factor analysis, and the two-dimension solution premise demonstrates better adjustment for both samples. The other psychometric properties explored show appropriate results for the Portuguese sample, and similar to the original ones; the Test therefore seems appropriate for use in cross cultural studies. Based on our results, we discuss whether the questionnaire is a one or two dimension instrument, concluding that it appears appropriate to accept the recommendations of the original authors to use it as a one-dimensional tool and, when necessary, to use both dimensions. - RESUMO: El objetivo del estudio es adaptar y discutir la adecuación de la prueba de Orientación de la Vida en una o dos escalas de dimensión. La investigación engloba dos estudios, uno constituido por una muestra secuencial de 280 personas con esclerosis múltiple, 71% mujeres y otro con una muestra de conveniencia de la comunidad de 615 individuos, 51,1% del sexo femenino. Como el constructo se asienta sobre la presunción teórica de que tiene una dimensión, inspeccionamos la hipótesis de una o dos soluciones de factor a través del análisis factorial confirmatorio y la hipótesis de dos dimensiones manifiesta un mejor ajuste para ambas muestras. Las otras propiedades psicométricas exploradas muestran los resultados apropiados para la muestra portuguesa, y semejantes a los originales. Parece apropiado para los estudios culturales transversales. Basándonos en nuestros resultados, discutimos si el cuestionario es un instrumento de una o dos dimensiones, concluyéndose que parece conveniente seguir las recomendaciones de los autores originales, para utilizarlo como un instrumento unidimensional y, si fuera necesario necesario, utilizar cada una de las dimensiones.

Orientation system for people with cognitive disabilities

In health care there has been a growing interest and investment in new tools to have a constant monitoring of patients. The increasing of average life ex-pectation and, consequently, the costs in health care due to elderly population are the motivation for this investment. However, healthmonitoring is not only important to elderly people, it can be also applied to people with cognitive disabilities. In this article we present some systems, which try to support these persons on doing their day-to-day activities and how it can improve their life quality. Also, we present an idea to a project that tries to help the persons with cognitive disabilities by providing assistance in geo-guidance and keep their caregivers aware of their location.

Considerações prévias: distinctions between academic and intellectual goals for young children

Lilian Katz refere-se à crescente tendência nos Estados Unidos de introduzir objetivos de caráter “académico” nos programas destinados a crianças pequenas, em alternativa a programas centrados simplesmente no jogo espontâneo. Katz propõe uma terceira alternativa que desenvolva as competências de caráter intelectual nas crianças, de modo a estimular o desenvolvimento das suas mentes e as suas sensibilidades morais e estéticas. Katz propõe a introdução do trabalho de projeto com crianças desde os primeiros anos.

Decisions with multiple simultaneous goals and uncertain causal effects

A key aspect of decision-making in a disaster response scenario is the capability to evaluate multiple and simultaneously perceived goals. Current competing approaches to build decision-making agents are either mental-state based as BDI, or founded on decision-theoretic models as MDP. The BDI chooses heuristically among several goals and the MDP searches for a policy to achieve a specific goal. In this paper we develop a preferences model to decide among multiple simultaneous goals. We propose a pattern, which follows a decision-theoretic approach, to evaluate the expected causal effects of the observable and non-observable aspects that inform each decision. We focus on yes-or-no (i.e., pursue or ignore a goal) decisions and illustrate the proposal using the RoboCupRescue simulation environment.
