Human peripheral blood V alpha 24(+) V beta 11(+) NKT cells expand following administration of alpha-galactosylceramide-pulsed dendritic cells

Background and Objectives We have undertaken the first clinical trial involving the administration of alpha-GalactosylCeramine (alpha-GalCer)-pulsed dendritic cells (DCs) to human subjects, to determine safety, optimal dose, optimal administration route and immunological effects. Materials and Methods Subjects (n = 4) with metastatic malignancy received two infusions of alpha-GalCer-pulsed DCs intravenously, and two infusions intradermally. The percentages of Valpha24 Vbeta11 NKT cells in peripheral blood (PB) were determined by three-colour flow cytometry and the PB NKT cell numbers were calculated using the total number of PB lymphocytes/ml determined by automated full-blood counts. Results No serious treatment related adverse events were observed during the study period. Administration of alpha-GalCer-pulsed DCs in vivo can significantly (P < 0.03) increase PB Valpha24(+) Vbeta11(+) NKT cell numbers above pretreatment baseline levels after the transient fall in the NKT numbers within 48 h. Conclusions Administration of alpha-GalCer-pulsed DCs is well tolerated, modulates PB Valpha24(+) Vbeta11(+) NKT cells and may have a role in the therapy of malignancies sensitive to activities of Valpha24(+) Vbeta11(+) NKT cells, or for autoimmune diseases.

Systemic administration of interleukin-1 beta activates select populations of central amygdala afferents

The central nucleus of the amygdala (CeA) is activated robustly by an immune challenge such as the systemic administration of the proinflammatory cytokine interleukin-1beta (IL-1beta). Because IL-1beta is not believed to cross the blood-brain barrier in any significant amount, it is likely that IL-1beta elicits CeA cell recruitment by means of activation of afferents to the CeA. However, although many studies have investigated the origins of afferent inputs to the CeA, we do not know which of these also respond to IL-1beta. Therefore, to identify candidate neurons responsible for the recruitment of CeA cells by an immune challenge, we iontophoretically deposited a retrograde tracer, cholera toxin b-subunit (CTb), into the CeA of rats 7 days before systemic delivery of IL-1beta (1 mug/kg, i.a.). By using combined immunohistochemistry, we then quantified the number of Fos-positive CTb cells in six major regions known to innervate the CeA. These included the medial prefrontal cortex, paraventricular thalamus (PVT), ventral tegmental area, parabrachial nucleus (PB), nucleus tractus solitarius, and ventrolateral medulla. Our results show that after deposit of CTb into the CeA, the majority of double-labeled cells were located in the PB and the PVT, suggesting that CeA cell activation by systemic IL-1beta is likely to arise predominantly from cell bodies located in these regions. These findings may have significant implications in determining the central pathways involved in generating acute central responses to a systemic immune challenge. J. Comp. Neurol. 452:288-296, 2002.

Desenvolvimento de compet??ncias de servidores na administra????o p??blica brasileira

Este artigo trata dos desafios de desenvolver as compet??ncias de servidores, de forma a melhorar a capacidade de governo na gest??o das pol??ticas p??blicas no Brasil. Na primeira parte, apresenta as caracter??sticas da administra????o p??blica brasileira em tr??s dimens??es: o modelo de carreiras dos servidores, o tipo de federalismo do Pa??s e o ambiente s??cio-econ??mico em que opera. Em seguida, analisa a nova pol??tica de desenvolvimento de pessoal (Decreto n??5.707/2006), que tem como foco a gest??o por compet??ncias, e o papel da ENAP na forma????o e capacita????o de dirigentes e servidores. Ao final, lan??a um desafio para a administra????o: a constru????o de um servi??o p??blico altamente capacitado e inovador, que atue dentro dos princ??pios da legalidade e da impessoalidade.

Fundamentos para uma pol??tica de carreiras no contexto da reforma gerencial

Com o advento da administra????o gerencial no ??mbito do aparelho do Estado, em complementa????o ?? administra????o burocr??tica, verifica-se certa turbul??ncia na gest??o de pessoal na administra????o p??blica, decorrente da s??bita aus??ncia de fundamentos conceituais s??lidos que permitam pensar a administra????o do capital humano do Estado em um contexto de transforma????o. Este artigo procura estabelecer as bases para a recupera????o destes fundamentos, propondo tr??s crit??rios de design de carreiras: a estrutura de incentivos, os mecanismos de governan??a e a gest??o do conhecimento. Em seguida, exemplifica-se a utiliza????o destes crit??rios pela an??lise de seis temas pr??prios ?? discuss??o sobre carreiras no servi??o p??blico: remunera????o, sele????o, recrutamento e desenvolvimento, mobilidade, promo????o, carreiras para ag??ncias executivas e controle social da burocracia.

Gest??o de pessoas no setor p??blico e a reprodu????o do discurso do setor privado

O objetivo deste estudo ?? o de estabelecer uma an??lise cr??tica do discurso contempor??neo em gest??o de pessoas, verificando como discurso e pr??tica gerencialistas se reproduzem no setor p??blico, sem que haja a devida an??lise do fator ideol??gico que permeia a gest??o privada. No contexto da idealiza????o de modelos gerenciais, gestores p??blicos s??o ??vidos em implementar modelos do setor privado, que t??m uma l??gica diferente da gest??o do setor p??blico. O artigo estabelece, dessa forma, a an??lise cr??tica desse processo, definindo elementos que possam inspirar a gest??o de organiza????es p??blicas e respeitar as suas especificidades.

Brazilian National School of Public Administration

The Brazilian National School of Public Administration (Escola Nacional de Administra????o P??blica ??? ENAP) is a public foundation linked to the Ministry of Planning, Budget and Management. Founded in 1986, its core mission is ???to develop competencies of civil servants in order to enhance government capacity for managing public policies???. To fulfill its mission, a wide program of learning and continued education is offered to public policy managers as well as e-learning and customized courses, in accordance to governmental and institutional strategic objectives. ENAP???s courses are framed according to governmental strategic demands for social inclusion, poverty reduction as well as economic development in order to strengthen the leading South American democracy. The range and diversity of its programs mirrors the challenges of deep changes in the jobs market and the work environment, faced by the current 550,000 federal civil servants and the over 7,000,000 state and municipal civil servants in Brazil, as last counted in 2006.

A gestão da capacitação baseada na gestão por competência : um estudo da viabilidade de implantação do sistema de capacitação do governo federal na UFES

A administração desde seu início desenvolveu vários modelos de gestão a fim de obter eficiência. Treinar, capacitar e desenvolver o pessoal esteve na maioria desses modelos como algo imprescindível para se alcançar os resultados desejados. O governo que há vários anos busca um serviço público profissional e de qualidade publicou o decreto n. 5.707/2006 que regulamenta o desenvolvimento de pessoal da administração pública autárquica e fundacional. Neste decreto ele institui que o desenvolvimento de servidores deverá seguir o modelo de Gestão por Competências. Este trabalho trata de verificar a possibilidade da implantação desse novo modelo de gestão para confeccionar o programa de capacitação dos servidores técnicos administrativos em educação da Universidade Federal do Espírito Santo (UFES) elaborando uma proposta de projeto. Nesse sentido, faz-se uma revisão dos conceitos de treinamento, capacitação, desenvolvimento, competências e gestão por competências e através de seus constructos levanta-se a viabilidade de implantação de um programa de capacitação que inter-relacione as exigências do cargo com as habilidades e competências apresentadas ou não pelo servidor e o conteúdo dos treinamentos e cursos oferecidos pelo Departamento de Desenvolvimento de Pessoas da UFES.

Security issues during Lula's administration: from the reactive to the assertive approach

Brazil's security agenda during Lula's administration was not homogeneous through the two mandates: the first tenure (2002-2006) revealed a reactive approach towards security topics, while the second one (2006-2010) was more assertive. More specifically, the shift occurred in terms of both its geographical scope - once it incorporated global issues in a more systematic way -, and instruments through which the security agenda was exercised, given the multilateral initiative of Unasur's CDS

Brazilian foreign policy towards South America during the Lula administration: caught between South America and Mercosur

The aim of this article is to analyze Brazil's foreign policy towards the South American region during President Lula's administration. As such, the article intends to highlight two specific dimensions: the extent to which foreign policy during this period has differed from previous periods and the relative importance granted by Brazilian diplomacy to recent cooperation and integration efforts, more specifically the Unasur and Mercosur. The article argues that the Lula administration has behaved differently from its predecessors by prioritizing the building up of Brazilian leadership in South America on several different fronts, especially by strengthening multilateral institutions in the region

Mapping the Obama administration's response to the Arab Spring

When the Arab Spring broke out, the United States was in a quandary over how to handle the crisis in its attempt to balance its moral obligations and ideals without undercutting its strategic interests and those of its close allies. Flaws in US diplomatic approach have contributed to one of the most serious foreign policy crisis for a US administration to date with consequential upheaval and erosion of the US-built balance of power. The reactions and policy responses of the Obama administration highlight the difficulties in grasping with the new reality in the Middle East and in enunciating a policy platform that could combine American interests and values.

Foucault’s Perspective of Performance Appraisal in Public Administration

The main purpose of performance appraisal in organizations is, or should be, to improve the engagement, learning process and progress of the employees and to align individual with team and organizational performance. However, performance appraisal can also be interpreted as an instrument of normalization, discipline and surveillance. This study thus aims to explore and discuss the complex schema of intrinsic and extrinsic objectives of performance appraisal system of the Portuguese public organizations (SIADAP - Performance Evaluation Integrated System). We have developed an exploratory and qualitative case study to capture appraisers and appraises perceptions. The data were analyzed in light of foucauldian theories. According to the qualitative data, namely the discourses of the appraisers and their subordinates, the SIADAP is seen as an instrument of control and dominance that aims to introduce political rationalities, limiting the career progression of the employees. Though some key points of Foucault’s perspective were identified, foucauldian framework revealed some limitations to capture all the complexity inherent to performance appraisal. This study opens new perspectives about the SIADAP and can be of major importance as far as political reflection about performance appraisal in public organizations is concerned.
