Effective acoustical monitoring tools for Mannophryne lamarcai

We performed the field-work during the dry (March 2014) and reainy season (May and June 2014) at the species type locality: Cerro Socopó, located at central-west region between Falcón, Lara and Zulia states, Venezuela. Socopó is a small and isolated mountain (1.571 m) belonging to the Ziruma mountains, and represents a relict of tropical mountain forest surrounded by semi-arid vegetation and grassland. This area is home to 312 species of vertebrates, including endangered and endemic amphibians species like Mannophryne lamarcai, Leptodactylus magistris and Dendropsophus amicorum. These forest and species are severely threatened by cattle ranch and illegal timber extraction, with forest formations only above 1000 meters. Despite this, no legal protected figure has been established in the area. We identified a 2.5 km secondary road transect within the study area based on the following criteria: 1) it cover different habitat types (streams and lagoons); and 2) it within the altitudinal gradient described for the specie (1,040 to 1,363 m). We identified three sampling points throughout the transect located in the vicinity of wetland habits: socopo1, socopo2 and socopo4. We did two types of recordings: 1) high quality recordings to characterize the advertisement call for M. lamarcai, non described to date (socopo4), and 2) recordings in different sampling points to evaluate call detectors performance in different acoustic scenarios (in all three localities).

Fatores preditivos de incapacidades em pacientes com hanseníase

OBJETIVO:Analisar os fatores preditivos na evolução do grau de incapacidade em pacientes com hanseníase. MÉTODOS:Foram analisados dados de coorte retrospectiva, que acompanhou 595 pacientes com incapacidades, registrados em uma unidade de saúde de Belo Horizonte (MG), de 1993 a 2003. Informações sociodemográficas e clínicas dos pacientes foram coletadas dos respectivos prontuários. Comparou-se o grau de incapacidade na admissão e no final do tratamento por meio do teste de homogeneidade marginal. Para identificar os fatores associados à evolução do grau de incapacidade foram utilizadas as análises univariada (teste qui-quadrado de tendência linear) e multivariada pelo algoritmo Chi-square Automatic Interaction Detector. RESULTADOS:Dos casos com registro de grau de incapacidade na admissão e na alta, observou-se que 43,2% que tinham grau 1 na primeira avaliação evoluíram para grau 0. Dos que apresentavam grau 2, 21,3% passaram a ter grau 0 e 20% passaram a grau 1. Na análise univariada as variáveis que se mostraram estatisticamente associadas à evolução no grau de incapacidade foram: neurite, tempo até a ocorrência de neurite, número de nervos acometidos, tipo de tratamento fisioterápico e maior dose de prednisona. Na análise multivariada, o principal fator que se associou à evolução do grau de incapacidade foi o grau de incapacidade na admissão. CONCLUSÕES:Os resultados mostraram a importância do diagnóstico precoce de neuropatia, assim como da eficiente associação das intervenções medicamentosas e não-medicamentosas por meio das técnicas de prevenção de incapacidade e dosagens adequadas de corticoterapia.

Qualidade de vida de pacientes com esquizofrenia internados em hospital de custódia

OBJETIVO: Investigar a qualidade de vida (QV) de pacientes com o diagnóstico de esquizofrenia que cumprem medida de segurança em regime fechado. MÉTODOS: Estudo epidemiológico com delineamento transversal, realizado com pacientes de um hospital de custódia. As entrevistas foram conduzidas utilizando questionário sociodemográfico e a escala de qualidade de vida Quality of Life Scale (QLS-BR), específica para pacientes com diagnóstico de esquizofrenia. Foi realizada análise descritiva e multivariada. A associação entre os escores de QV e as características clínicas, sociodemográficas e do delito foi obtida por análise multivariada, através da árvore de decisão, por meio do algoritmo Chi-squared Automatic Interaction Detector (CHAID). RESULTADOS: Participaram deste estudo 54 pacientes, sendo 90,7% do sexo masculino, com a média de idade de 40 anos. Todos os domínios de qualidade de vida, inclusive o global, apresentaram escores compatíveis com uma QV muito baixa. O domínio ocupacional apresentou-se como o mais comprometido. Maior duração da doença, ter cometido homicídio e estar com idade superior a 40 anos foram as variáveis associadas a uma baixa qualidade de vida pela análise multivariada. CONCLUSÃO: Evidenciou-se uma baixa QV dos pacientes que cumprem medida de segurança em regime fechado, realidade que precisa ser modificada a partir da viabilização de mudanças nas políticas brasileiras.

Why do they separate it or not? Attitudes and behaviors towards organic waste separation

This article shows the results of an exploratory study related to the separation of organic waste in order to offer suggestions for the improvement of waste disposal communication campaigns. The overall objective is to analyze attitude and behavior of those who do and those who do not separate organic waste, related to a specific promotional campaign carried out in two neighborhoods, in the municipality of Badalona (Spain), within the framework of the study of proenvironmental attitudes and behaviors and based on the Psychosocial Four Spheres Model. 1,010 interviews were conducted and data was analyzed using Chi-Squared Automatic Interaction Detector (CHAID). Waste separation behavior was used as a dependent variable. The reasons given to explain why people do or do not separate organic waste and sociodemographic variables, have been introduced as independent variables. In accordance with the Four Spheres Model, results show significant differences in waste separation. Based on the profiles obtained, we find some predictive variables that facilitate the development of communication campaigns according to the requirements of each community.

Identificazione dei fenotipi clinici dell’insufficienza renale cronica che predicono la progressione della malattia. Un’applicazione della tecnica degli alberi decisionali

The primary aim of this dissertation to identify subgroups of patients with chronic kidney disease (CKD) who have a differential risk of progression of illness and the secondary aim is compare 2 equations to estimate the glomerular filtration rate (GFR). To this purpose, the PIRP (Prevention of Progressive Kidney Disease) registry was linked with the dialysis and mortality registries. The outcome of interest is the mean annual variation of GFR, estimated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. A decision tree model was used to subtype CKD patients, based on the non-parametric procedure CHAID (Chi-squared Automatic Interaction Detector). The independent variables of the model include gender, age, diabetes, hypertension, cardiac diseases, body mass index, baseline serum creatinine, haemoglobin, proteinuria, LDL cholesterol, tryglycerides, serum phoshates, glycemia, parathyroid hormone and uricemia. The decision tree model classified patients into 10 terminal nodes using 6 variables (gender, age, proteinuria, diabetes, serum phosphates and ischemic cardiac disease) that predict a differential progression of kidney disease. Specifically, age <=53 year, male gender, proteinuria, diabetes and serum phosphates >3.70 mg/dl predict a faster decrease of GFR, while ischemic cardiac disease predicts a slower decrease. The comparison between GFR estimates obtained using MDRD4 and CKD-EPI equations shows a high percentage agreement (>90%), with modest discrepancies for high and low age and serum creatinine levels. The study results underscore the need for a tight follow-up schedule in patients with age <53, and of patients aged 54 to 67 with diabetes, to try to slow down the progression of the disease. The result also emphasize the effective management of patients aged>67, in whom the estimated decrease in glomerular filtration rate corresponds with the physiological decrease observed in the absence of kidney disease, except for the subgroup of patients with proteinuria, in whom the GFR decline is more pronounced.

Development of a high sensitive automatic setup for screening of microcystins in surface waters by employing a LED-based photometric detector

In this manuscript, an automatic setup for screening of microcystins in surface waters by employing photometric detection is described. Microcystins are toxins delivered by cyanobacteria within an aquatic environment, which have been considered strongly poisonous for humans. For that reason, the World Health Organization (WHO) has proposed a provisional guideline value for drinking water of 1 mu g L-1. In this work, we developed an automated equipment setup, which allows the screening of water for concentration of microcystins below 0.1 mu g V. The photometric method was based on the enzyme-linked immunosorbent assay (ELISA) and the analytical signal was monitored at 458 nm using a homemade LED-based photometer. The proposed system was employed for the detection of microcystins in rivers and lakes waters. Accuracy was assessed by processing samples using a reference method and applying the paired t-test between results. No significant difference at the 95% confidence level was observed. Other useful features including a linear response ranging from 0.05 up to 2.00 mu g L-1 (R-2 =0.999) and a detection limit of 0.03 mu g L-1 microcystins were achieved. (C) 2011 Elsevier B.V.

Call recognition and individual identification of fish vocalizations based on automatic speech recognition: An example with the Lusitanian toadfish

The study of acoustic communication in animals often requires not only the recognition of species specific acoustic signals but also the identification of individual subjects, all in a complex acoustic background. Moreover, when very long recordings are to be analyzed, automatic recognition and identification processes are invaluable tools to extract the relevant biological information. A pattern recognition methodology based on hidden Markov models is presented inspired by successful results obtained in the most widely known and complex acoustical communication signal: human speech. This methodology was applied here for the first time to the detection and recognition of fish acoustic signals, specifically in a stream of round-the-clock recordings of Lusitanian toadfish (Halobatrachus didactylus) in their natural estuarine habitat. The results show that this methodology is able not only to detect the mating sounds (boatwhistles) but also to identify individual male toadfish, reaching an identification rate of ca. 95%. Moreover this method also proved to be a powerful tool to assess signal durations in large data sets. However, the system failed in recognizing other sound types.

Towards the Automatic Merging of Lexical Resources: Automatic Mapping

Lexical Resources are a critical component for Natural Language Processing applications. However, the high cost of comparing and merging different resources has been a bottleneck to have richer resources with a broad range of potential uses for a significant number of languages.With the objective of reducing cost byeliminating human intervention, we present a new method for automating the merging of resources,with special emphasis in what we call the mapping step. This mapping step, which converts the resources into a common format that allows latter the merging, is usually performed with huge manual effort and thus makes the whole process very costly. Thus, we propose a method to perform this mapping fully automatically. To test our method, we have addressed the merging of two verb subcategorization frame lexica for Spanish, The resultsachieved, that almost replicate human work, demonstrate the feasibility of the approach.
