Ecologia e história natural de população Hemidactylus agrius (Squamata: Gekkonidae) em área de Caatinga, com avaliação da distribuição das espécies nativas do gênero no nordeste do Brasil

The genus Hemidactylus Oken, 1817 has cosmopolite distribution, with three species occurring in Brazil, two of them native, H. brasilianus and H. agrius, and one exotic, H. mabouia. Considering the studies about ecology of lizards conducted in the Ecological Station of the Seridó, from 2001 to 2011, this study aimed (1) to re-evaluate the occurrence of the species of Hemidactylus in this ESEC; (2) to analyze ecological and biological aspects of the H. agrius population; and (3) to investigate the current and potential distribution of the native species of the genus in northeastern Brazil, analyzing the suitability of ESEC to this taxon. For the first two objectives, a sampling area consisting of five transects of 200 x 20 m, was inspected in alternating daily shifts for three consecutive days, from August 2012 to August 2013. For the latter objective, occurrence points of H. agrius and H. brasilianus from literature and from the database of Herpetological Collections of the UFRN and the UNICAMP were consulted to build predictive maps via the Maximum Entropy algorithm (MaxEnt). In ESEC Seridó, 62 H. agrius individuals were collected (25 females, 18 males and 19 juveniles), and two neonates were obtained from a communal nest incubated in the laboratory. No record was made for the other two species of the genus. Hemidactylus agrius demonstrated to be a nocturnal species specialized in habitats with rocky outcrops; but this species is generalist regarding microhabitat use. In the population studied, females had an average body length greater than males, and showed higher frequencies of caudal autotomy. Regarding diet, H. agrius is a moderately generalist species that consumes arthropods, especially insect larvae, Isoptera and Araneae; and vertebrates, with a case of cannibalism registered in the population. With respect to seasonal differences, only the number of food items ingested differed between seasons. The diet was similar between sexes, but ontogenetic differences were recorded for the total volume and maximum length of the food items. Significant relationships were found between lizard body/head size measurements and the maximum length of prey consumed. Cases of polydactyly and tail bifurcation were recorded in the population, with frequencies of 1.6% and 3.1%, respectively. In relation xv to the occurrence points of the native species, 27 were identified, 14 for H. agrius and 13 for H. brasilianus. The first species presented restricted distribution, while the second showed a wide distribution. In both models generated, the ESEC Seridó area showed medium to high suitability. The results of this study confirm the absence of H. brasilianus and H. mabouia this ESEC, and reveal H. agrius as a dietary opportunist and cannibal species. Further, the results confirm the distribution patterns shown by native species of Hemidactylus, and point ESEC Seridó as an area of probable occurrence for the species of the genus, the establishing of H. brasilianus and H. mabouia are probably limited by biotic factors, a fact yet little understood

Influência do horário de trabalho, do gênero e de um programa de educação sobre o sono no ciclo sono/vigília de professores do ensino fundamental e médio

The teaching profession is often associated with extensive workload inside and outside the classroom, poor teaching conditions, among other challenges that can cause sleep problems. These problems may be even greater in women, due to the professional and domestic work hours and to the major sleep necessity. Considering that sleeping problems may result from the practice of poor sleep habits, sleep education programs are conducted with the aim to reduce sleep deprivation, irregularity on sleep schedules, daytime sleepiness and improve sleep quality. In this sense, the objective of this study is to evaluate the influence of working hours, gender and a sleep education program on sleeping habits, quality of sleep, daytime sleepiness and the level of stress in teachers of elementary and secondary education. For that, teachers filled the questionnaires that assessed: 1. Sleeping habits (Sleep & Health), 2. Chronotype (Horne & Ostberg), 3. Daytime sleepiness (Epworth Sleepiness Scale), 4. Sleep Quality (Pittsburgh Sleep Quality Index), 5. Level of stress (The Inventory of Stress for Adults of Lipp) and 6. Daily pattern of sleep/wake cycle (Sleep Diary). The questionnaires 1, 4, 5 and 6 were repeated 3 weeks after the sleep education program. Teachers who begin work in the morning (7:11 ± 0:11 h) wake up earlier in the week and often have poor sleep quality compared to those who start in the afternoon (13:04 ± 00:12 h). Among those who begin work in the morning, the intermediate types and those with an evening tendency were more irregular in the wake up time than morning types and increased sleep duration on weekend. In relation to gender, women had longer sleep duration than men, although the majority presented excessive daytime sleepiness and poor sleep quality. However, when work schedule and age are similar between genders, the difference in sleep duration becomes a tendency and the difference in the percentage of excessive daytime sleepiness disappears, but the poor sleep quality persists in women. With respect to teachers who have gone through the sleep education program, there was an increase in knowledge about the subject, which may have contributed to the reduction in the frequency of coffee consumption close to bedtime and to the sleep quality improved in 18 % of participants. In the control group, there were random differences in knowledge in 3rd stage, and sleep quality improved in only 9% of teachers. The participation in the sleep education program was not enough to change the hours of sleep and decrease stress of teachers. Therefore, the start time school in the morning was preponderant in determining the wake up time of teachers, especially for intermediates types and those with an evening tendency. Furthermore, the poor quality of sleep was more common in women, and the sleep education program contributed to increase knowledge on the subject and to improve sleep quality.

Escola: lugar político da diversidade sexual e de gênero

This work aims to understand how the public school system has become a failing institution with regards to sexual and gender diversity. I start from the principle that the school system performs a social sorting operation, leaving out of its halls almost all people who don‘t fit into the established heteronormative social order. First, I explore the experiences of primary school (Educação do Ensino Fundamental) professionals from the public network (Rede Pública Municipal) of the city of Natal-RN. I consider their narratives a result of daily practices which denounce the rules that govern and produce them in a broader context. Then I aim to establish a dialogue with the students who are victims of name-calling, teasing and abuse for not aligning with the ―normal‖ gender standards. At this stage of the research, I conducted fieldwork at the State Secondary School of Rio Grande do Norte (Escola Estadual de Ensino Médio). This investigation is guided by the following questions: What challenges need to be addressed in order to recognize the students who have been excluded from the school environment on account of sexual and/or gender differences; additionally, how can their classroom attendance and positive learning experience be ensured? To what degree is the school community concerned with building education practices which value and acknowledge sexual and gender diversity? The research goals were: to analyze how the school and its professionals deal with sexual and gender diversity, investigating which pedagogical practices silence, freeze and obstruct the diversity of student identities; examine how the school and its subjects work toward building new pathways for learning, for coexistence, and for facing the challenges of ―new‖ social demands such as homoaffection; observe the spaces that are cracked open by the presence and the voices of students who demand recognition of their existence.

Prevalência da síndrome metabólica em receptores de transplante renal de acordo com o gênero e tempo pós-transplante /

Metabolic syndrome (MS) is defined as a set of cardiovascular risk factors including obesity, systemic high blood pressure (SHBP), changes in glucose metabolism and dyslipidemia. The prevalence of MS in renal transplant recipients (RTR) ranges from 15% to 65%, increasing the risk of cardiovascular disease (CVD) and reducing renal allograft survival in the long term. The objectives of this study were to determine the prevalence and frequency of MS in renal transplant patients according to gender and time of transplantation and to evaluate renal function in patients with and without MS. Patients and Methods: Crosssectional study conducted from August 2012 to September 2013 involving 153 renal transplant recipients. MS was defined according to the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III). The sample was divided into two groups: patients with metabolic syndrome (WMS patients) and patients without metabolic syndrome (WoMS patients) and according to gender. The WMS patients were stratified into quartiles according to the renal transplantation period (RTP), and variables related to MS were analyzed for both sexes. Results: MS was diagnosed in 58.1% of the studied population, specifically in MS was found 58.4% of men and 41.6% of women (P ˂ 0.05). The male and female with MS were 48.8 ± 11.6 years old vs. 47.1 ± 12.7 years old and the time of post transplantation was 76.1 ± 76.5 months vs. 84.7 ± 65.4 months, respectively (P >0,05). When we compared the sexes in the WMS group, systolic blood pressure (SBP) was higher in men (137.0 ± 18.1 vs. 128.9 ± 13.6 mmHg, P= 0.029), while the other components of MS did not exhibit significant differences. With respect to renal function, when we compared the sexes in the WMS group, the serum creatinine (sCr) was higher in men (1.73 ± 0.69 vs. 1.31 ± 0.47 mg/dL, P= 0.0012), while the urinary protein/creatinine ratio was higher in women (0.48 ± 0.69 vs. 0.37 ± 0.48 mg/dL, P=0.0150). We found no significant difference in the estimated glomerular filtration rate (eGFR) between WMS and WoMS patients for women and men (50.6 ± 19.1 vs. 50.1 ± 18.3 mL/min/1.73 m², P=0.909). We found a significant positive association between eGFR and HDL-c levels (r=0.3371; P=0.0145) for WMS men. The MS components showed no significant differences in RTP for different interquartile ranges, except for diastolic blood pressure (DBP) in women, where there was a significant variation among the quartiles evaluated (P=0.0009). Conclusion: the prevalence of MS was similar in the different quartiles in both sexes, in relation to time post TX. There was no significant difference in eGFR in patients WMS and WoMS, in both sexes. Concluding that the MS did not vary in relation to time post transplant.

A diferença de género na resolução de conflitos existentes entre os militares da Força Aérea

O conflito, quando abordado de forma construtiva, pode criar oportunidades e crescimento, mas se abordado de forma incorreta pode gerar estagnação. É por isso que uma gestão eficaz e salutar dos conflitos é fundamental para otimizar as suas consequências e transformá-las em mais valias de forma a que impulsione a mudança. A entrada das mulheres nas Forças Armadas fez ressaltar a importância da discussão da diferença do género na resolução dos conflitos interpessoais. No nosso trabalho de investigação analisamos, através de um estudo quantitativo, uma amostra de 421 militares (110 mulheres e 311 homens) no sentido de aferir quais os comportamentos mais frequentes no local de trabalho relativamente a uma situação de conflito interpessoal e se existem diferenças entre os géneros ao lidarem com o conflito. Para a recolha de dados foi utilizado o ROCI-II (Rahim Organizational Conflict Inventory-II). Os resultados obtidos indicam que em todos os tipos de relações interpessoais o estilo integração é o predominante independente do sexo. Da análise efetuada, dentro de cada estilo de Gestão de Conflito não se verificaram diferenças significativas em função do género exceto no estilo evitamento em que este é mais utilizado pelas mulheres em todas as relações interpessoais. Abstract: The conflict, when approached constructively, can create opportunities and growth; but if approached incorrectly it can lead to stagnation. Therefore, an effective and constructive management is essential to optimize its consequences and turn them into capital gains that drive the change. The entry of women in the military did emphasize the importance of the discussion about gender difference in solving interpersonal conflicts. In our research work we analyze, through a quantitative study, a sample of 421 military personnel (110 women and 311 men) in order to assess which are the most frequent types of behavior in the context of an interpersonal conflict in the workplace and if there are differences between genders in dealing with conflict. For data collection ROCI-II (Rahim Organizational Conflict Inventory-II) was used. The results obtained indicate that in all types of interpersonal relationships the integration style is predominant regardless of sex. From the analysis conducted, inside each style of Conflict Management there are no significant differences based on gender, except regarding the avoidance style, which is more used by women in all interpersonal relationships.

Resistência de germoplasma do gênero Manihot quanto ao ácaro-rajado (Tetranychus urticae).

O objetivo deste trabalho foi avaliar acessos do gênero Manihot quanto à resistência ao ácaro-rajado. Foram utilizados 58 tratamentos, constituídos de 13 cultivares de mandioca utilizadas na alimentação humana, 30 acessos do BAG de mandioca da Embrapa Semiárido e 13 acessos de espécies silvestres de Manihot, da coleção de Manihot da Embrapa Semiárido, e dois prováveis híbridos naturais (Pornunça e Manipeba). A avaliação da resistência dos acessos ao ácaro-rajado foi realizada aos 6 meses após o plantio, quando a infestação era visível. Foi utilizada uma escala de danos que variou de 1 a 5. Houve diferenças significativas para reação ao ácaro (P?0,01). No teste de médias, as notas variaram de 1 a 3. De acordo com estes dados há variabilidade para resistência a ácaro-rajado entre os acessos avaliados, com possíveis fontes de resistência. No entanto, novas avaliações devem ser realizadas para comprovar os resultados obtidos

Caracterização morfológica das sementes e plântulas de seis espécies invasoras do gênero Solanum L

Morphological caracterization of the seeds and seedlings of six weed especies of the genus Solanum L. The seeds of the genus Solanum are very similar, however, the association of their external characteristics with the anatomical features, such as hilum shape, the texture and the type of the seed coat sculptures, as well as the curved (circulated or coiled) shape of the embryo, are parameters of great importance in the taxonomical identification at the species level. It is are presented the morphological descriptions of the genus Solanum and a more detailed description of each studied species in terms of seed and seedling structures, including illustrations and taxonomical keys for the identification of Solanum aculeatissimum Jacq., S. americanum Mill., S. ciliatum Lam., S. sisymbriifolium Lam., S. sordidum Sendt. e S. viarum Dunal. There are also indications of the common names, the type of reproduction and dispersion, the crops in which the species is considered as a weed and the agricultural seeds in which it is found as a weed seed.

As diferenças rítmicas entre o português europeu e o português brasileiro: uma abordagem otimalista e minimalista

The aim of this paper is to discuss some rhythmic differences between European and Brazilian Portuguese and their relationship to pretonic vowel reduction phenomena. After the basic facts of PE and PB are presented, we show that the issue cannot be discussed without taking into account secondary stress placement, and we proceed to present the algorithm-based approach to secondary stress in Portuguese, representative of Metrical Phonology analyses. After showing that this deterministic approach cannot adequately explain the variable position of secondary stress in both languages regarding words with an even number of pretonic syllables, we argue for the interpretation of secondary stress and therefore for the construction of rhythmic units at the PF interface, as suggested in Chomsky s Minimalist Program. We also propose, inspired by the constrain hierarchies as proposed in Optimality Theory, that such interpretation must take into account two different constraint rankings, in EP and BP. These different rankings would ultimately explain the rhythmic differences between both languages, as well as the different behavior of pretonic vowels with respect to reduction processes.
