Discourses of cyberspace securitization in Brazil and in the United States

Abstract This paper uses the framework of the Copenhagen School to understand the process of securitization of cyberspace, exploring how something in such sphere becomes a threat. Seeking to contribute to the debate, this study analyses the securitization discourses of Brazil and of the United States from Hansen and Nissenbaum's (2009) theorization about the existence of a specific sector for cybersecurity. To comprehend the securitization of cyberspace in these terms allows not only to identify distinct levels of securitization, but also to capture the dynamics of cyber threats, distinguishing them from those existent in other sectors, as well as to trace distinctions between tendencies of securitization and militarization.

Exposure to psychosocial risk factors in the context of work: a systematic review

ABSTRACT OBJECTIVE To analyze the scientific literature about the effects of exposure to psychosocial risk factors in work contexts. METHODS A systematic review was performed using the terms “psychosocial factors” AND “COPSOQ” in the databases PubMed, Medline, and Scopus. The period analyzed was from January 1, 2004 to June 30, 2012. We have included articles that used the Copenhagen Psychosocial Questionnaire (COPSOQ) as a measuring instrument of the psychosocial factors and the presentation of quantitative or qualitative results. German articles, psychometric studies or studies that did not analyze individual or work factors were excluded. RESULTS We included 22 articles in the analysis. Individual factors, such as gender, age, and socioeconomic status, were analyzed along with work-related factors such as labor demands, work organization and content, social relationships and leadership, work-individual interface, workplace values, justice and respect, personality, health and well-being, and offensive behaviors. We analyzed the sample type and the applied experimental designs. Some population groups, such as young people and migrants, are more vulnerable. The deteriorated working psychosocial environment is associated with physical health indicators and weak mental health. This environment is also a risk factor for the development of moderate to severe clinical conditions, predicting absenteeism or intention of leaving the job. CONCLUSIONS The literature shows the contribution of exposure to psychosocial risk factors in work environments and their impact on mental health and well-being of workers. It allows the design of practical interventions in the work context to be based on scientific evidences. Investigations in specific populations, such as industry, and studies with more robust designs are lacking.

Resistance of Musca domestica L. populations to cyromazine (insect growth regulator) in Brazil

Five field populations of Musca domestica L. collected in poultry farms were bioassayed in order to detect possible resistance to the larvicide cyromazine in Brazil. The concentrations used were 0, 0.5, 0.1, 0.2, 0.4, 1, 2, 4 and 8 ppm. Three populations (Petrópolis, RJ, Montes Claros, MG and Promissão, SP) were resistant, while the other two populations (Ibiuna, SP and Monte Mor, SP) were more susceptible than the reference pathern used by the World Health Organization. The presence of three resistant house fly populations to cyromazine in Brazilian poultry farms strongly suggests that the operational aspects of larvicide use are important for the resistance development. Cyromazine is applied as a feed-through, both in Brazil and in the USA, where resistance has already been documented. However, in Denmark, where it was approved only as a topical manure spray, no case of resistance has yet been detected.

Congenital toxoplasmosis and DALYs in the Netherlands

The calculation of disability-adjusted life years (DALYs) enables public health policy makers to compare the burden of disease of a specific disease with that of other (infectious) diseases. The incidence of a disease is important for the calculation of DALYs. To estimate the incidence of congenital toxoplasmosis (CT), a random sample of 10,008 dried blood spot filter paper cards from babies born in 2006 in the Netherlands were tested for Toxoplasma gondii-specific IgM antibodies. Eighteen samples were confirmed as positive for IgM, resulting in an observed birth incidence of CT of 1.8 cases per 1,000 live-born children in 2006 and an adjusted incidence of 2.0 cases per 1,000. This means that 388 infected children were born in 2006. The most likely burden of disease is estimated to be 2,300 DALYs (range 820-6,710 DALYs). In the previous calculations, using data from a regional study from 1987, this estimate was 620 DALYs (range 220-1,900 DALYs). The incidence of CT in the Netherlands is much higher than previously reported; it is 10 times higher than in Denmark and 20 times higher than in Ireland, based on estimates obtained using the same methods. There is no screening program in the Netherlands; most children will be born asymptomatic and therefore will not be detected or treated.

Portraying innovation in the public service of Brazil: Frameworks, systematization and characterization

ABSTRACT Innovation is essential for improving organizational performance in both the private and public sectors. This article describes and analyzes the 323 innovation experiences of the Brazilian federal public service that received prizes during the 16 annual competitions (from 1995 to 2012) of the Award for Innovation in Federal Public Management held by the Brazilian National School of Public Administration (ENAP). It is a qualitative and quantitative study in which were employed as categories for analysis the four types of innovation defined in the Copenhagen Manual: product, process, organizational and communication. The survey results allow us to affirm that there is innovation in the public sector, in spite of the skepticism of some researchers and the incipient state of theoretical research on the subject. It was possible to observe that organizational innovation was the one with the highest number of award- -winning experience, followed respectively by process, communication and product innovation, with citizen services and improvement of work processes being the main highlights. The results showed that, although the high incidence of innovation occurs at the national level, a significant number of innovations also occur at the local level, probably because many organizations of the federal government have their actions spread only at this level of government. Concerning the innovative area, health and education predominate, with almost 33% of initiatives, which can be explained by capillarity of these areas and the fact that both maintain a strong interaction with the user. The contributions of this work include the use of theoretical model of innovation analysis in the public sector in Brazil still upcoming, and the systematization of knowledge in empirical basis for this innovation. In this sense, it also contributes to the development of the theory with the presentation of evidence that the characteristics, determinants and consequences of innovation in the public sector differ not only from innovation in the industry, but also from innovation in services in the private sector.

SELETIVIDADE DE CHLORFENAPYR E FENBUTATIN-OXIDE SOBRE DUAS ESPÉCIES DE ÁCAROS PREDADORES (ACARI: PHYTOSEIIDAE) EM CITROS

Com o uso de bioensaios, verificaram-se os efeitos residual de contato, ovicida e de persistência dos produtos chlorfenapyr e fenbutatin-oxide sobre duas espécies de ácaros predadores, Iphiseiodes zuluagai Denmark & Muma e Euseius alatus DeLeon (Acari: Phytoseiidae), associados ao ácaro da leprose-dos-citros Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae). O efeito total sobre os adultos foi estudado por meio do método residual de contato com pulverização em superfície de vidro, conforme metodologia da IOBC. O efeito ovicida foi avaliado por meio de pulverização direta sobre os ovos dos ácaros predadores, também em superfície de vidro. A persistência dos produtos foi avaliada em laboratório, em arenas confeccionadas com folhas de laranjeira pulverizadas no campo, aos 0; 5; 15 e 30 dias após a aplicação. Os resultados obtidos mostraram que chlorfenapyr foi nocivo ao I. zuluagai e E. alatus e o fenbutatin-oxide foi levemente nocivo a E. alatus e inócuo a I. zuluagai. Nenhum dos produtos apresentou efeito ovicida. Fenbutatin-oxide apresentou baixa persistência para ambas as espécies de ácaros predadores, e chlorfenapyr, na dosagem de 31,3 ml, foi de baixa persistência, enquanto, na dosagem de 62,5 ml, foi moderadamente persistente. O fenbutatin-oxide apresentou-se inócuo e levemente nocivo aos ácaros predadores I. zuluagai e E. alatus, respectivamente, e de baixa persistência para ambas as espécies
