Résumé :
Este trabalho apresenta o filtro de Kalman como uma ferramenta para o pré-processamentode sinais espectrofotométricos no contexto da quimiometria. Inicialmente são introduzidos os principais conceitos sobre o filtro de Kalman. O filtro de Kalman é usado com amostras de aço-ligas. O sinal filtrado é usado na calibração multivariada para construir um modelo matemático com boa capacidade preditiva. A eficiência do filtro é demonstrada utilizando um conjunto de dados obtidos por um espectrofotômetro de emissão atômica em plasma com baixa resolução para tratar o problema da determinação simultânea do Manganês (Mn), Molibdênio (Mo), Cromo (Cr), Níquel (Ni) e Ferro (Fe). Os resultados obtidos demonstram que o filtro de Kalman pode ser aplicado com vantagens em relação a outras técnicas tradicionais em quimiometria como filtro de média móvel.

Résumé :
ABSTRACT This study examines the impact of the Securities and Exchange Commission's (SEC) XBRL (eXtensible Business Reporting Language) mandate on the timeliness of financial reporting, measured by the reporting lag between fiscal period end and the filing date. Using annual and quarterly filing data from 2007 to 2014, we compare the reporting lags of XBRL reports to the lags of non-XBRL reports in three separate filing categories as defined by the SEC. The results show that by using XBRL the reporting lag is shortened by one to two days when companies file annual reports while the reporting lag is shortened by one day in quarterly filings. However, the results are manifest for both large accelerated filers and accelerated filers. In the multivariate analysis, we do not observe the improved reporting lag when using XBRL among non-accelerated filers. While we provide the evidence that the XBRL mandate improves the timeliness of financial reporting for large filers, we question the public policymaking of the XBRL mandate that has the intention of benefiting small companies and their investors.

Résumé :
Small ruminants in northwestern Spain are frequently managed in mixed flocks. Sheep–goat joint management has not been considered a risk factor for parasite infection, so the main objective of this study was to establish if mixed management with goats supposes a risk factor for parasitic infections in ovine flocks. Two thousand and ninety-three sheep were sampled from 74 commercial meat ovine flocks for diagnostic of the main parasites. Goat contact was a risk factor for sheep to be infected by protostrongylids, Dictyocaulus filaria, gastrointestinal nematodes and Eimeria spp. In contrast, Moniezia, Fasciola hepatica, Dicrocoelium dendriticum and Paramphistomidae prevalences were not influenced. Sheep–goat mixed management can be considered as a risk factor, since goats would act as a source of pasture contamination for interspecific parasites (protostrongylids, Dictyocaulus filaria and gastrointestinal nematodes). In relation to host-specific parasites, such as Eimeria spp., goats cannot be considered as a source for sheep, but competition for food and spaces between both small ungulates can suppose a reduced grazing area to sheep, provoking high environmental contamination and stress that facilitate their infection. Future epidemiological studies for parasitic infections in small ruminants should consider sheep–goat mixed management as a possible risk factor to be included in multivariate analyses.

Résumé :
ABSTRACT We compared the age profiles of infection and specific antibody intensities in two communities with different transmission levels in East Africa to examine the contribution of humoral responses to human immunity to the vector-borne helminth Wuchereria bancrofti. The worm intensities were higher and exhibited a nonlinear age pattern in a high-transmission community, Masaika, in contrast to the low but linearly increasing age infection profile observed for a low-transmission community, Kingwede. The mean levels of specific immunoglobulin G1 (IgG1), IgG2, IgG4, and IgE were also higher in Masaika, but intriguingly, the IgG3 response was higher in Kingwede. The age-antibody patterns differed in the two communities but in a manner apparently contrary to a role in acquired immunity when the data were assessed using simple correlation methods. By contrast, multivariate analyses showed that the antibody response to infection may be classified into three types and that two of these types, a IgG3-type response and a response measuring a trade-off in host production of IgG4 and IgG3 versus production of IgG1, IgG2, and IgE, had a negative effect on Wuchereria circulating antigen levels in a manner that supported a role for these responses in the generation of acquired immunity to infection. Mathematical modeling supported the conclusions drawn from empirical data analyses that variations in both transmission and worm intensity can explain community differences in the age profiles and impacts of these antibody response types. This study showed that parasite-specific antibody responses may be associated with the generation of acquired immunity to human filarial infection but in a form which is dependent on worm transmission intensity and interactions between immune components.

Résumé :
As variações na precipitação refletem claramente a dinâmica atmosférica de uma determinada região. Tal conhecimento permite o auxílio na execução de atividades humanas como agricultura, monitoramento ambiental, defesa civil, entre outras. O objetivo deste estudo foi verificar os elementos climatológicos relacionados com o aumento/redução nos valores pluviométricos para a cidade de Maceió, no período de 1961 a 2015. As séries de dados de precipitação de duas estações próximas foram cedidas pelo Instituto Nacional de Meteorologia (INMET) e pela Usina Utinga Leão. A metodologia consistiu em utilizar o filtro paramétrico Hodrick-Prescott (HP) para detectar tendências na série de dados, o método de análise de ondeletas para verificar a influência de escalas temporais na precipitação de Maceió e ainda a utilização do Índice Multivariado de ENOS (IME) e o Índice da Oscilação Decadal do Pacífico (IPDO) para verificar a atuação das anomalias de Temperatura da Superfície do Mar (ATSM) na variabilidade do índice pluviométrico. A partir dos resultados, observou-se através da análise de tendência, uma redução na precipitação principalmente no início da década de 1980, e de forma mais acentuada no final da década de 1990. As ondeletas identificaram a influência da escala sazonal na precipitação local e por meio da associação dos índices IPDO e IME, constatou-se um aumento no número de eventos extremos de precipitação quando a Oscilação Decadal do Pacífico (ODP) se configura na fase fria e redução relativa do índice de precipitação quando o IME apresenta valores elevados. De modo geral o estudo detalhado do comportamento pluviométrico de Maceió aprimora o entendimento climático visando mitigar os possíveis impactos hidrometeorológicos, podendo auxiliar o planejamento urbano e ambiental da cidade.

Résumé :
Vector Borne Diseases are diseases that cause many problems. These diseases are spread by mosquitoes as the vectors. They transmit parasites to humans through their bites. The people who live in Indonesia have several characteristics that make them vulnerable to these diseases. Therefore, it is necessary to explore these characteristics in order to gain better prevention promotional targeting strategy. This study aims to determine the factors that can influence mosquito bite prevention behaviour in Indonesian society. The data from a nationwide survey research were used with a cross sectional design conducted once in every five years. The Riskesdas was conducted from April to May 2018 in all districts in Indonesia. The influencing factors observed were including experience of exposure to vector borne diseases (malaria or filariasis), gender, age group, education level and area of residence. This study conducted a multivariate test using logistic regression analysis to determine the factors that influence mosquito bite prevention behaviour. The results demonstrated that the factors of experience of exposure to vector borne diseases, gender, age group, education level and area of residence could determine the mosquitoes bite prevention behaviour in Indonesian society. Respondents who have experience of being exposed to malaria or filaria, under 60 years old, women, college graduates, and rural communities are more likely to prevent mosquito bites, therefore they could be empowered in promoting public awareness towards mosquito bites prevention.

Résumé :
A elevada incidência de doenças de veiculação hídrica é atribuída à inadequação dos sistemas de esgotamento sanitário nas áreas rurais do semiárido brasileiro. O uso da radiação solar é uma alternativa na desinfecção de águas residuárias para fins de aproveitamento agrícola, sendo de baixo custo, fácil operação e que não gera subprodutos carcinogênicos oriundos da cloração. Diante do exposto, o presente trabalho tem a finalidade de identificar as variáveis determinantes no processo de desinfecção solar em águas cinza no semiárido potiguar. A estação de tratamento de águas cinza é composta por tanque séptico, filtro anaeróbio e reator solar. Os ensaios experimentais foram realizados no período de julho a dezembro de 2015, com frequência mensal e empregou-se às técnicas de estatística descritiva e multivariada. No reator solar foram mantidas lâminas de águas cinza de 0,1 m, que ficaram expostas à radiação solar durante período entre 8:00 às 16:00 h, e coletadas alíquotas a cada duas horas. As amostras coletadas foram submetidas às análises de pH, oxigênio dissolvido, temperatura, condutividade elétrica, sólidos suspensos totais, turbidez, coliformes totais, coliformes termotolerantes e ovos de helmintos. Paralelamente, foram monitoradas, também, a temperatura do ar e radiação solar global. Pelo emprego da Análise de Componentes Principais, foi identificado um modelo de melhor ajuste composto por três componentes, explicando 79,46% da variância total. Sendo a primeira componente microbiológica, a segunda climática e a terceira componente, relacionada aos sais. O nível populacional médio de E.coli após 8 horas de exposição solar foi de 2,16E+03 tornando possível apenas o reúso restrito. Em relação às análises de ovos de helmintos, cabe salientar que não foram observados ovos em nenhuma das amostras de águas cinza bruta como, também, nas amostras de águas cinza após tratamento solar.

Résumé :
As plantas daninhas competem com as culturas por fatores limitantes do meio em que vivem, portanto, estudos que apontem a resposta germinativa de sementes submetidas a estresses artificiais são importantes para entender a capacidade de sobrevivência e adaptação destas espécies sob condições de estresse naturais. Objetivou-se neste trabalho avaliar o efeito das condições salinas e térmicas sobre a germinação e vigor de sementes de Amaranthus deflexus L. Foram instalados dois experimentos, com semeadura realizada em placas de petri contendo duas folhas de papel de filtro umedecidas com água destilada (controle) ou com soluções de NaCl. No experimento 1 utilizou-se o delineamento experimental inteiramente casualizado (DIC), em esquema fatorial 2 x 6, constituído de dois fotoperíodos (12h luz e 24h escuro) e seis níveis de estresse salino (0; -0,3; -0,6; -0,9; -1,2 e -1,5 MPa), totalizando doze tratamentos, com quatro repetições. Ao final do teste, as sementes que não germinaram foram lavadas e colocadas em substrato papel toalha, umedecido com água para hidratação e estimular o processo germinativo. No experimento 2 utilizou-se um DIC com oito tratamentos (germinação sob 20; 25; 30; 35; 40°C, 20/30; 25/35 e 30/40°C) e quatro repetições cada. O estresse salino afetou negativamente o vigor das sementes de A. deflexus desde o nível de estresse de -0,3 MPa. O vigor das sementes foi comprometido pela ausência de luz, independentemente dos níveis de estresse aplicados. Houve superioridade na percentagem final de germinação e o índice de velocidade de germinação das sementes de A. deflexus na temperatura de 25°C constante e no regime alternado de 25-35°C. O procedimento multivariado discriminou os tratamentos 1 e 2 como superiores no dendograma A, bem como 4, 5 e 6 no dendograma B, configurando-se como método robusto para inferência em experimentos fatoriais sobre o comportamento germinativo.

Subyek penelitian dibagi menjadi kelompok kasus dan kelompok kontrol masing-masing 74 orang. Variabel bebas yang dikaji dalam penelitian ini adalah spesies keberadaan nyamuk di dalam dan luar rumah, kawat kasa, persawahan, saluran air, genangan air, tumbuhan air, dan ternak. Faktor perilaku meliputi kebiasaan penggunaan kelambu, menggantung pakaian, penggunaan obat anti nyamuk, keluar ada malam hari, pengetahuan dan layanan kesehatan. Variabel terikatnya adalah kejadian filariasis. Pengumpulan data dilakukan dengan wawancara, observasi, dan penangkapan nyamuk. Analisis data hasil penelitian menggunakan regresi logistik.Hasil: Dari 17 variabel bebas yang dikaji, hasil penelitian ini menemukan ada tiga variabel yang mempunyai asosiasi signifikan dengan kejadian filatiasis di Kecamatan Buaran Kabupaten Pekalongan. Variabel tersebut meliputi tinggal di sekitar rumah penderita, kepadatan hunian, dan kepatuhan minum obat. Hasil analisis regresi logistik menunjukkan bahwa kepadatan hunian merupakan faktor yang paling dominan pengaruhnya terhadap kejadian filariasis dengan OR=6,145 (CI:1,051 – 35,938).Simpulan: Penelitian ini menyimpulkan bahwa tinggal di sekitar rumah penderita, kepadatan hunian dan kepatuhan minum obat filariais mempunyai kontribusi terhadap kejadian filariasis. Peneliti menyarankan upaya perbaikan lingkungan yang sehat dan kepatuhan minum obat oleh masyarakat perlu diupayakan semaksimal mungkin guna menekan kejadian penyakit tersebut di masa mendatang. AbstractTitle: Factors Related toThe Incidence of Lymphatic Fillariasis in Buaran, Pekalongan DistrictBackground: Filariasis or elephansiasis is one of infectious disease, is a systemic infection caused by filarial worms that live in the lymph nodes (lymph) and human blood that transmitted by mosquitoes (vector-borne disease). The survey result endemicity of filariasis in 2007 found that the highest area was in Buaran District with the number of microfilariae (mf) rate of 3.9% and according to the data Filariasis Research 2015, the result of Finger-prick Blood in Subdistrict Buaran discovery of microfilariae are 37 people. Based on this fact the purpose of this research is to describe environmental condition and behaviour society as a risk factor for the incidence of filariasis in Subdistrict Buaran Pekalongan regency.Method: This study was observational study with case control design. The subjects consisted of two groups of case and control, with each sample of 74 people. The independent variables studied were the vectors inside and outside the home existing, marshes existing, rice fields existing, trenches existing, ditches, puddles, aquatic plants existing, bushes existing, cattle existing, wire netting on the ventilation esiting, the habit of using nets, habits of hanging clothes have been used, the habit of using anti-mosquito drugs, the habit outdoors at night, knowledge and health efforts. While the dependent variable was the incidence of filariasis. Data was collected through interviews, observation, and measurement. Data would be analyzed using univariate, bivariate chi-square, and multivariate logistic regression at level of significance 0.05 (5%).Result: Bivariate analyze of 17 variables are the vectors inside and outside the home existing, marshes existing, rice fields existing, trenches existing, ditches, puddles, aquatic plants existing, bushes existing, cattle existing, wire netting on the ventilation esiting, the habit of using nets, habits of hanging clothes have been used, the habit of using anti-mosquito drugs, the habit outdoors at night, knowledge and health efforts, indicated that there were three variables that have a correlation to incidence of filariasis. They were staying or being around filariasis sufferers, density residential, and medication adherence. Results of multivariate analysis that density residential is the most dominant factor related to the incidence of filariasis with p-value = 0.044; OR = 6,145 (1,051 - 35,938). Conclusion: This study concluded that environment factors need to be improved, especially for staying or being around filariasis sufferers, density residential, and medication adherence to reduce fillariasis incident.

Résumé :
Purpose This study aims to examine the timing of corporate disclosure in the context of Georgia, an emerging market where a recent reform of corporate financial transparency mandated about 80,000 private sector entities to publicly disclose their annual financial statements. Design/methodology/approach The main analysis covers more than 4,000 large, medium, small and micro private sector entities, for which the data is obtained from the Ministry of Finance of Georgia. This paper builds an empirical model of logit/probit regression, with industry fixed and random effects to investigate the drivers of the corporate disclosure timing. Findings Findings suggest that the mean reporting time lag is 279 days after the fiscal year-end, that is nine days after the statutory deadline. Almost one-third (30%) of the entities miss the nine-month statutory deadline, while the timely filers almost unexceptionally file immediately before the deadline. Multivariate tests reveal that voluntarily filing entities completed the process significantly faster than those mandated to do so; audited financial statements take more time to be filed, whereas those with unqualified audit opinion or audited by large/international audit firms are filed faster than their counterparts. The author concludes that despite the overall high filing rates, the timing of corporate disclosure is not (yet) efficiently enforced in practice (but is progressing over time), whereas regulatory incentives prevail over market incentives among the timely filers. Originality/value To the best of the author’s knowledge, this is the first study that explores corporate disclosure timing incentives in the context of Georgia. This study extends prior literature on the timing of financial information from an emerging country’s private sector perspective, with juxtaposed market and regulatory incentives.
