Seeds Potentialities of Medicks in Sub-Humid Area to be used in Steppe Zone

New pulse crops varieties more productive as medics should be made available to breeders located in semi-arid region of Algeria. So, and through two years of testing, pods yield and seeds production of twenty populations belonging to species M.intertexta , M.ciliaris, M.polymorpha , M.Truncatula and an introduced population M.muricoleptis is an Australian cultivar (Jemalong) are appreciated.Pods' yields of year 2013 vary between 78,66g/m² with poly27 and 3637,33g/m² with I107. Values of the second essay (2015) are different, they vary between 40,89g /m² with Poly236 and 464,36 g/m² with I11.The cultivar Jemalong offers a yield of 172,4 g/m². The corresponding seed yields also show a low production in year 2015. The ratio leaf / stem varies between 1,03 and 5. The average of yields in dry matter of 27 populations in 2013 was of 457,79g/m2 against 127,41 g/m² in 18 populations in 2015. Jemalong cultivar records a yield of 12,8g/m². For the same dose of seed, number of plants by square meter varies between 44 and 112. Number of stems by square meter varies between 136 in C204 and 420 in I52..The average width of population's ramifications varies between 13cm in Tr334 and 44 cm in I52, The Jemalong cultivar offers an average of 17cm. So, production results of medicks depend of weather conditions in littoral zone of lower altitude than 600-700m. In steppe zones, we recommend to make tests in situ with these same populations

Perdas extremas em mercados de risco

This paper aims to infer about the distribution of extremes values of a continuous random variable, represented as the severe daily losses in financial markets investments. The Extreme Value Theory (EVT) plays a fundamental role in modeling rare events associated with great losses and very small probabilities of occurrence. One of the great concerns in risk management is to develop analytic techniques to foresee those exceptions. In that way, the tails of the rare losses' probability density function (pdf) are of great importance in evaluating that kind of risk, turning EVT into a valuable tool for an accurate evaluation of high loss risks. The estimations of expected maximum losses in financial series are investigated by means of: i) traditional methods, which used all sample data in fitting the random variable pdf; ii) the Extreme Value methodology, particularly the Generalized Extreme Value distribution (GEV), which only used a set of maximum values detected in the sample data in estimating the pdf of expected maximum losses. The findings indicate, firstly, an important underestimation of extreme losses with the traditional methods, mainly in the pdf lower tail limits, and, secondly, that the GEV distribution proved to be more efficient in forecasting extreme losses in the analyzed series: Ibovespa, Merval, Dow Jones.Neste artigo, infere-se sobre a distribuição de valores extremos de uma variável aleatória representada pelas severas perdas diárias em investimentos financeiros. A Teoria dos Valores Extremos (TVE) fundamenta a modelagem de eventos gravosos raros, com expressivas conseqüências econômicas associadas a probabilidades muito pequenas de ocorrerem. Uma das grandes preocupações, na análise de riscos, é desenvolver técnicas para prever essas ocorrências excepcionais. Assim, as caudas das distribuições desses eventos raros são importantes para o estudo do risco, tornando a TVE uma ferramenta de grande valia para a estimação mais acurada do risco dessas perdas elevadas. Investigou-se, neste trabalho, a estimação de perdas máximas esperadas para séries financeiras, empregando-se: i) métodos tradicionais, que utilizaram todos os dados amostrais para analisar a variável aleatória em questão e ii) a metodologia dos Valores Extremos, particularmente a da Distribuição Generalizada dos Valores Extremos (DGVE), que utilizou apenas um conjunto de máximos amostrais para a estimação das perdas máximas esperadas. Concluiu-se que os métodos tradicionais subestimaram as perdas esperadas, sobretudo nas proximidades dos limites das caudas das distribuições, e que a DGVE mostrou-se bem mais eficiente na previsão dessas perdas extremas nas séries analisadas: Ibovespa, Merval, Dow Jones

Urban Termites of Recife, Northeast Brazil (Isoptera)

This study surveyed the termite fauna in urban properties of the city of Recife, state of Pernambuco, northeastern Brazil. Six-hundred properties were inspected in search for termites or signs of their activity, such as abandoned nests, galleries on walls, and fecal pellets. Seven termite species, belonging to seven genera and three families (Kalotermitidae, Rhinotermitidae, and Termtidae) were found causing some type of damage. Nasutitermes corniger and Cryptotermes dudleyi were the most frequent species within buildings (82.4% and 9.5 %, respectively). Such species, along with Coptotermes gestroi, were responsible for the greatest damage recorded. With the exception of Cryptotermes dudleyi and Coptotermes gestroi, all of the species are native and relatively common in northeastern Brazil’s Atlantic forest

Specificity of facial expression labeling deficits in childhood psychopathology

Background: We examined whether face-emotion labeling deficits are illness-specific or an epiphenomenon of generalized impairment in pediatric psychiatric disorders involving mood and behavioral dysregulation. Method: Two hundred fifty-two youths (7-18 years old) completed child and adult facial expression recognition subtests from the Diagnostic Analysis of Nonverbal Accuracy (DANVA) instrument. Forty-two participants had bipolar disorder (BD), 39 had severe mood dysregulation (SMD; i.e., chronic irritability, hyperarousal without manic episodes), 44 had anxiety and/or major depressive disorders (ANX/MDD), 35 had attention-deficit/hyperactivity and/or conduct disorder (ADHD/CD), and 92 were controls. Dependent measures were number of errors labeling happy, angry, sad, or fearful emotions. Results: BD patients made more errors than ANX/MDD, ADHD/CD, or controls when labeling all emotional expressions, whether those expressions were on the faces of children or adults. SMD also showed emotion-labeling deficits, in particular as compared to ANX/MDD patients and controls. Conclusions: Face-emotion labeling deficits differentiate BD and SMD patients from those with ANX/MDD or ADHD/CD and controls. The extent to which such deficits cause vs. result from emotional dysregulation requires further study

Evaluation Model of Virtual Learning Environments: A Pilot Study

Virtual learning environments (VLE) have frequently been used in educational practices, and the evaluation of their effectiveness as instruments to support learning gains must consider several dimensions. This paper presents an evaluation model for VLE, called MA-AVA (Model for the Evaluation of VLE), built after a review of the literature and focused on verifying students\u27 learning gains. The MA-AVA evaluation model was applied in a pilot study to an undergraduate engineering class, using a VLE, Educ-MAS-GA, in the discipline of Analytical Geometry. The results indicate that, although students\u27 perception of learning in VLE is relevant, the knowledge acquired is more subtle and difficult to assess. Therefore, a VLE learning evaluation model should include different dimensions of learning, such as the students’ perceptions and their measures of learning gain

What's In My Big Data?

Large text corpora are the backbone of language models. However, we have a limited understanding of the content of these corpora, including general statistics, quality, social factors, and inclusion of evaluation data (contamination). In this work, we propose What's In My Big Data? (WIMBD), a platform and a set of sixteen analyses that allow us to reveal and compare the contents of large text corpora. WIMBD builds on two basic capabilities -- count and search -- at scale, which allows us to analyze more than 35 terabytes on a standard compute node. We apply WIMBD to ten different corpora used to train popular language models, including C4, The Pile, and RedPajama. Our analysis uncovers several surprising and previously undocumented findings about these corpora, including the high prevalence of duplicate, synthetic, and low-quality content, personally identifiable information, toxic language, and benchmark contamination. For instance, we find that about 50% of the documents in RedPajama and LAION-2B-en are duplicates. In addition, several datasets used for benchmarking models trained on such corpora are contaminated with respect to important benchmarks, including the Winograd Schema Challenge and parts of GLUE and SuperGLUE. We open-source WIMBD's code and artifacts to provide a standard set of evaluations for new text-based corpora and to encourage more analyses and transparency around them: github.com/allenai/wimbd

Immunogenicity and seroefficacy of 10-valent and 13-valent pneumococcal conjugate vaccines: a systematic review and network meta-analysis of individual participant data

Background: Vaccination of infants with pneumococcal conjugate vaccines (PCV) is recommended by the World Health Organization. Evidence is mixed regarding the differences in immunogenicity and efficacy of the different pneumococcal vaccines. Methods: In this systematic-review and network meta-analysis, we searched the Cochrane Library, Embase, Global Health, Medline, clinicaltrials.gov and trialsearch.who.int up to February 17, 2023 with no language restrictions. Studies were eligible if they presented data comparing the immunogenicity of either PCV7, PCV10 or PCV13 in head-to-head randomised trials of young children under 2 years of age, and provided immunogenicity data for at least one time point after the primary vaccination series or the booster dose. Publication bias was assessed via Cochrane's Risk Of Bias due to Missing Evidence tool and comparison-adjusted funnel plots with Egger's test. Individual participant level data were requested from publication authors and/or relevant vaccine manufacturers. Outcomes included the geometric mean ratio (GMR) of serotype-specific IgG and the relative risk (RR) of seroinfection. Seroinfection was defined for each individual as a rise in antibody between the post-primary vaccination series time point and the booster dose, evidence of presumed subclinical infection. Seroefficacy was defined as the RR of seroinfection. We also estimated the relationship between the GMR of IgG one month after priming and the RR of seroinfection by the time of the booster dose. The protocol is registered with PROSPERO, ID CRD42019124580. Findings: 47 studies were eligible from 38 countries across six continents. 28 and 12 studies with data available were included in immunogenicity and seroefficacy analyses, respectively. GMRs comparing PCV13 vs PCV10 favoured PCV13 for serotypes 4, 9V, and 23F at 1 month after primary vaccination series, with 1.14- to 1.54- fold significantly higher IgG responses with PCV13. Risk of seroinfection prior to the time of booster dose was lower for PCV13 for serotype 4, 6B, 9V, 18C and 23F than for PCV10. Significant heterogeneity and inconsistency were present for most serotypes and for both outcomes. Two-fold higher antibody after primary vaccination was associated with a 54% decrease in risk of seroinfection (RR 0.46, 95% CI 0.23–0.96). Interpretation: Serotype-specific differences were found in immunogenicity and seroefficacy between PCV13 and PCV10. Higher antibody response after vaccination was associated with a lower risk of subsequent infection. These findings could be used to compare PCVs and optimise vaccination strategies.

Nationwide and regional incidence of microbiologically confirmed pulmonary tuberculosis in South Africa, 2004-12 : a time series analysis

BACKGROUND : South Africa has the highest incidence of tuberculosis in the world, largely resulting from a high population prevalence of HIV infection. We investigated the incidence of microbiologically confirmed pulmonary tuberculosis, and new cases of pulmonary tuberculosis registered for treatment, nationally and provincially in South Africa from 2004 to 2012, during which time there were changes in antiretroviral therapy (ART) coverage among individuals with HIV infection. METHODS : We identifi ed cases of microbiologically confi rmed pulmonary tuberculosis from 2004 to 2012 from the National Health Laboratory Service Corporate Data Warehouse. New cases registered for treatment were identifi ed from National Department of Health electronic registries. A time series analysis, using autoregressive models, was undertaken on incidence of microbiologically confi rmed pulmonary disease nationally and provincially; this trend was also examined relative to ART coverage of adults with HIV infection. FINDINGS : During the 9-year period, 3 523 371 cases of microbiologically confirmed pulmonary tuberculosis were recorded nationally. Annual incidence (per 100 000 population) increased from 650 (95% CI 648–652) in 2004 to 848 (845–850) in 2008, declining to 774 (771–776) by 2012 (9% decrease from 2008 to 2012). Incidence varied by age group, sex, and province. There was an inverse association between incidence of microbiologically confirmed disease and ART coverage among HIV-infected individuals nationally and provincially. Trends in incidence of tuberculosis cases registered for treatment mirrored those of microbiologically confirmed cases nationally and provincially; however, incidence of microbiologically confirmed cases was consistently higher than cases registered for treatment nationally and in seven of nine provinces. INTERPRETATION : Since its peak in 2008, the incidence of microbiologically confirmed pulmonary tuberculosis in South Africa had declined by 2012; this decline is associated with an increase in ART coverage. Future integration of registries for microbiologically confirmed cases and new cases registered for treatment would improve the assessment of the burden of pulmonary tuberculosis in South Africa.

"Now he walks and walks, as if he didn't have a home where he could eat": food, healing, and hunger in Quechua narratives of madness

In the Quechua-speaking peasant communities of southern Peru, mental disorder is understood less as individualized pathology and more as a disturbance in family and social relationships. For many Andeans, food and feeding are ontologically fundamental to such relationships. This paper uses data from interviews and participant observation in a rural province of Cuzco to explore the significance of food and hunger in local discussions of madness. Carers’ narratives, explanatory models, and theories of healing all draw heavily from idioms of food sharing and consumption in making sense of affliction, and these concepts structure understandings of madness that differ significantly from those assumed by formal mental health services. Greater awareness of the salience of these themes could strengthen the input of psychiatric and psychological care with this population and enhance knowledge of the alternative treatments that they use. Moreover, this case provides lessons for the global mental health movement on the importance of openness to the ways in which indigenous cultures may construct health, madness, and sociality. Such local meanings should be considered by mental health workers delivering services in order to provide care that can adjust to the alternative ontologies of sufferers and carers
