Inovação aberta na gestão pública: análise do plano de ação brasileiro para a Open Government Partnership

Este estudo objetivou analisar o Plano de Ação brasileiro para o Governo Aberto, baseado na teoria da inovação aberta na gestão pública. Utilizou-se de uma pesquisa documental, com vistas a aprofundar o conhecimento do fenômeno em questão. O documento foi escolhido intencionalmente, por ser exemplo basilar das políticas públicas relacionadas à inovação aberta brasileira. Os resultados mostram que os compromissos firmados pelo governo brasileiro estão consoantes com o processo de inovação aberta pública. As ações previstas no Plano estão especificamente relacionadas a transparência, abertura de dados e preparação do corpo estatal para o processo aberto de inovação.

Problema da falta de vagas em creches: matriz de loops e a priorização de causas de problemas complexos

Dez milhões de crianças brasileiras deveriam frequentar creches, mas apenas 21% delas estão regularmente matriculadas. O problema da falta de vagas em creches foi o cenário escolhido para evidenciar a utilidade do artefato proposto: procedimentos para análise de problemas complexos, composto pela aplicação integrada entre mapa causal e matriz de loops, duas técnicas associadas aos estudos de padrões de cognição nas organizações. O artefato proposto foi testado junto a três municípios brasileiros, segundo os preceitos da abordagem design science. Causas e associações intercausais foram identificadas e priorizadas pela técnica de mapa causal e, posteriormente, interdependências entre causas foram analisadas pela técnica matriz de loops, o que alterou a priorização inicial. Evidenciou-se que para problemas complexos é fundamental identificar e analisar os loops entre loops de amplificação de desvio (loops "explosivos"). Outro resultado a destacar é a melhor compreensão de um problema complexo e socialmente relevante.

Mid-point for open-ended income category and the effect of equivalence scales on the income-health relationship

To estimate the mid-point of an open-ended income category and to assess the impact of two equivalence scales on income-health associations. Data were obtained from the 2010 Brazilian Oral Health Survey ( Pesquisa Nacional de Saúde Bucal – SBBrasil 2010). Income was converted from categorical to two continuous variables ( per capita and equivalized) for each mid-point. The median mid-point was R$ 14,523.50 and the mean, R$ 24,507.10. When per capita income was applied, 53% of the population were below the poverty line, compared with 15% with equivalized income. The magnitude of income-health associations was similar for continuous income, but categorized equivalized income tended to decrease the strength of association.

Laparoscopic versus open splenectomy in the management of hematologic diseases

Splenectomy is the best available treatment for severe forms of hereditary spherocytosis, idiopathic thrombocytopenic purpura, and other hematologic conditions when these prove refractory to conservative management. It has been employed for many decades with low mortality and favorable remission rates. The use of laparoscopic splenectomy in recent years has been rapidly and even enthusiastically adopted in this field. However, the exact role of laparoscopic versus open surgery for hematologic diseases is still debated. In this study of 58 adult patients, laparoscopic procedures were compared with conventional splenectomies for similar indications. METHODS: All patients were operated on within an 8-year period. Subjects underwent similar procedures under the supervision of the same surgical school and were compared regarding age, gender, body mass index, and diagnosis. Laparoscopically managed cases (Group I, n = 30) were prospectively followed according to a written protocol, whereas the same investigation was retrospectively done with regard to traditional laparotomy (Group II, n = 28). Methods included general and demographic findings, duration and technical steps of operation, blood loss, weight of spleen, need for conversion (in minimally invasive subjects), intraoperative and postoperative complications, time until realimentation, postoperative hospitalization, mortality, and late follow-up including recurrence rate. RESULTS: Idiopathic thrombocytopenic purpura was the surgical indication in over 50% of the patients in both groups, but familial spherocytosis, thalassemia, myelodysplasia, and lymphomas were also represented in this series. Laparoscopic procedures took more time to perform (P = 0.004), and postoperative hospitalization was 2 days shorter, but this difference was not statistically significant. Postoperative hematocrit and volume of blood transfusions was equivalent, although the laparoscopic cases had a somewhat lower preoperative hematocrit (NS) and displayed better recovery for this measurement (P = 0.03). More patients in Group I were able to accept oral food on the first day than subjects undergoing conventional operations (P < 0.05). Relatively few conversions were necessary during the minimally invasive surgeries (13.3%), and postoperative early and late complications as well as recurrences occurred in similar proportions. Also, the mean weight of the spleen was not statistically different between the groups, although there was a marked numerical tendency toward larger masses in conventional procedures. No spleen in Group I exceeded 2.0 kg, whereas in Group II values up to 4.0 kg occurred, and the mean weight was 50% higher in the latter group. CONCLUSIONS: 1) Minimally invasive splenectomy was essentially comparable to open surgery with regard to safety, efficacy, and late results; 2) Advantages concerning shorter postoperative hospitalization could not be shown, despite earlier food intake and a non-significant tendency toward earlier discharge; 3) This new modality should be considered an option in cases of hematologic conditions whenever the spleen is not hugely enlarged.

A multicenter, open-label study of the efficacy and safety of telmisartan in mild to moderate hypertensive patients

OBJECTIVE: To evaluate the efficacy and tolerability of telmisartan, given once a day to patients with mild to moderate hypertension, as well as to assess the 24-hour blood pressure profile with ABPM. METHODS: Initially, 163 patients over 18 were selected, regardless of sex, with blood pressure levels >140/90mmHg at visit 1, which was confirmed at visit 2. One hundred thirty-four patients completed the study. After a 4-week placebo run-in phase, telmisartan 40mg/daily was given for 6 weeks. In those patients whose blood pressure (BP) levels were lower than 140/90mmHg, the same dosage was kept for an additional period of 6 weeks. For those who had BP higher than 140/90mmHg, the dosage was increased to 80mg/daily. Sixty-two patients were included in a subgroup that underwent ABPM 3 different times during the study. RESULTS: In the overall group, blood pressure reduction ranged from 162.3±14.5/101.3±5.75 mmHg (baseline) to 147.3±20.1/90.8±10.9 mmHg (week 12) (p<0.05). Mean blood pressure decreases were 14.4mmHg for systolic BP and 10.3mmHg for diastolic BP, after 12 weeks of active treatment. A subanalysis showed that 47 (35%) patients took telmisartan 40mg throughout the study and 81 (65%) had the dosage increased to 80mg daily. Using ABPM, an 8-mmHg reduction in systolic BP as well as a 5-mmHg reduction in diastolic BP were observed, when compared with baseline values in the final 6 hours (18-24 hours after the last dose of study medication). CONCLUSION: Our results confirm that telmisartan given once a day is effective in reducing blood pressure levels in mild to moderate hypertensive patients. This reduction occurs in a sustained and gradual manner during a 24-hour period confirmed by ABPM.

Notas sobre cromossômios de alguns escorpiões brasileiros

Three species of Scorpions beloging to two different families were studied cytologically: a) Tityus mattogrossensis Borelli (Fam. Buthidae), - This species presents spermatogonia provided with 20 short chromosomes which orient at metaphase with their axis parallelly to the plane of the equator and move toward the poles without changing this position, from the stage pachytene to metaphase the bivalents become, as in Tityus bahiensis, progressivery shorter and thicker, without showing that chiasmata occured at any time. The paired chromosomes never open themselves, out to form loops as in orthodox meioses. As in Tityus bahiensis the bivalents are inserted In the spindle before reaching their maxim contraction. No diakinesis has been observed. The primary spermatocyte metaphases are provided, with 10 pairs of chromosones, two of which are larger and two smaller than the rest. The bivalents orient as in Tityus bahiensis with their length in the plane of the equator and separate parallelly. Spindle fibres are seen alongst their entire body. While, in Tityus bahiensis the ends of the chromosomes are pronouncedly turned to opposite poles at metaphase, nothing like this was observed in the present species. Only late in anaphase the chromosomes of Tityus mattogrossensis show a bending to the poles. The secondary spermatocytes present 10 short chromosomes, two being larger than, the others. Here, on the contrary, the chromosomes are strongly curved toward the poles since the beginning of anaphase. Some chromosomal anomalies have been noticed. Primary spermatocytes with 14 bivalents, some of which representing probably free fragments, were observed. Primary spermatocytes with 8 bivalents and one cross of 4 chromosomes were interpreted as resulting from breakages followed by translocations Primary spermatocytes with 9 bivalents, one of which being much longer than the longst of the normal plates, show that fusion by the extremities of two non homologous chromosomes on the onde side, and of their respective homologous in the same way on tre other, have occured. Orientation of bivalents with their body parallelly to the spindle axis and anaphasic bridges have been encountered. All in all points to the conclusion that the chromosomes of Tityus mattogrossesis, like those of Tityus bahiensia are provided with one kinetochore at each end. Ananteris balzani Thorell - (Fam. Buthidae). - This species which belongs to the same family as Tityus, is provided with 12 chromosomes (diploid). These studied in embryonic tissues, showed the same behavior as the somatic chromosomes of Tityus bahiensis. Bothrirus sp. (Bothriuridae). - Only spermatogonia were found in the testis, of the single male hitherto investigated. The chromosomes, in number of 36, are of different sizes but small and provided, as ordinarily, with a single kinetochore. They behave therefore in an orthodox manner in mitosis.

Seasonal dynamics of a drosophilid (Diptera) assemblage and its potencial as bioindicator in open environments

Drosophila Fallen, 1823 (Diptera, Drosophilidae) is for long a well-established model organism for genetics and evolutionary research. The ecology of these flies, however, has only recently been better studied. Recent papers show that Drosophila assemblies can be used as bioindicators of forested environment degradation. In this work the bioindicator potential of drosophilids was evaluated in a naturally opened environment, a coastal strand-forest (restinga). Data from nine consecutive seasonal collections revealed strong temporal fluctuation pattern of the majority of Drosophila species groups. Drosophila willistoni group was more abundant at autumns, whereas D. cardini and D. tripunctata groups were, respectively, expressive at winters and springs, and D. repleta group at both seasons. The exotic species D. simulans Sturtevant, 1919 (from D. melanogaster group) and Zaprionus indianus Gupta, 1970 were most abundant at summers. Overall, the assemblage structure did not show the same characteristics of forested or urban environments, but was similar to the forests at winters and to cities at summers. This raises the question that this locality may already been under urbanization impact. Also, this can be interpreted as an easily invaded site for exotic species, what might lead to biotic homogenization and therefore can put in check the usage of drosophilid assemblages as bioindicators at open environments.

A New Species of Simulium (Diptera: Simuliidae) from Open Areas in Central Amazonia, Brazil

The larva, pupa, male and female of Simulium daltanhani n. sp. are described and illustrated. This species shares diagnostic characteristics with Simulium quadrifidum Lutz, Simulium cauchense Floch & Abonnenc, Simulium brevifurcatum Lutz and Simulium siolii Py-Daniel. It was collected in three counties (Manaus, Presidente Figueiredo and Itacoatiara) in the State of Amazonas, Brazil. Its habitat includes streams in disturbed, open areas where the forest has been cut for road construction; it was not collected in adjacent forested streams, suggesting that it colonizes disturbed habitats. The larval subesophageal ganglion is discussed as a useful character, when pigmented, to distinguish this species within a limited geographic area.

What is the importance of open habitat in a predominantly closed forest area to the dung beetle (Coleoptera, Scarabaeinae) assemblage?

What is the importance of open habitat in a predominantly closed forest to the dung beetle assemblage? The Atlantic Forest in Brazil is one of the most highly disturbed ecosystems and is mainly represented by fragmented areas. However, in places where human disturbances have ceased, certain areas are showing a natural regeneration pattern. The aim of the present study was to determine how the dung beetle assemblage responds to distinct habitat structures in a fragment of Atlantic Forest. For such, open and closed forest areas were sampled in a fragment of the Atlantic Forest in the northeastern region of Brazil. Pitfall traps baited with excrement and carrion were used to collect the beetles. A total of 7,267 individuals belonging to 35 species were captured. Canthon chalybaeus and C. mutabilis were restricted to open areas. Nearly 90% of the individuals of C. aff. simulans and Deltochilum aff. irroratum were identified in these areas. A higher percentage (> 50%) of Canthon staigi, Dichotomius aff. depressicolis and D. aff. sericeus occurred in closed areas. Abundance differed between areas, with higher values in closed areas. Richness was not influenced by the habitat structure. NMDS ordination exhibited the segregation of areas and ANOSIM confirmed that this variable explained the assemblage of dung beetle species. The findings of the present study validate that open areas are associated to more restrictive conditions, limiting a higher abundance of dung beetle. Although situated near preserved fragments, the studied open areas increase the heterogeneity of the general landscape.

Ammonia losses estimated by an open collector from urea applied to sugarcane straw

The quantification of ammonia (NH3) losses from sugarcane straw fertilized with urea can be performed with collectors that recover the NH3 in acid-treated absorbers. Thus, the use of an open NH3 collector with a polytetrafluoroethylene (PTFE)-wrapped absorber is an interesting option since its cost is low, handling easy and microclimatic conditions irrelevant. The aim of this study was to evaluate the efficiency of an open collector for quantifying NH3-N volatilized from urea applied over the sugarcane straw. The experiment was carried out in a sugarcane field located near Piracicaba, São Paulo, Brazil. The NH3-N losses were estimated using a semi-open static collector calibrated with 15N (reference method) and an open collector with an absorber wrapped in PTFE film. Urea was applied to the soil surface in treatments corresponding to rates of 50, 100, 150 and 200 kg ha-1 N. Applying urea-N fertilizer on sugarcane straw resulted in losses NH3-N up to 24 % of the applied rate. The amount of volatile NH3-N measured in the open and the semi-open static collector did not differ. The effectiveness of the collection system varied non-linearly, with an average value of 58.4 % for the range of 100 to 200 kg ha-1 of urea-N. The open collector showed significant potential for use; however, further research is needed to verify the suitability of the proposed method.

Open archives: caminho alternativo para a comunicação científica

A comunicação científica ampliou seus horizontes de troca de dados, informações e conhecimentos com o aparecimento dos open archives, arquivos que congregam e-prints das diversas áreas do saber e que são abertos à consulta pública, bem como à publicação automatizada dos trabalhos por parte dos pesquisadores. A experiência americana em áreas da física, matemática e ciência da computação, entre outras, demonstra a viabilidade e utilidade dos arquivos abertos como ponto de convergência para comunidades de pesquisadores que se vêem sem fronteiras geográficas ou institucionais para o intercâmbio de seus resultados de pesquisas.
