Sex, a one mans show : Perceptions and experience of sexuality, contraceptives, unwanted pregnancy and unsafe abortion among young people in Kisumu, Kenya – A qualitative study

This study aimed to explore perceptions and experiences concerning sexuality, contraceptives, unwanted pregnancy and unsafe abortion among young people in Kisumu, Kenya. The design of the study was inductive with a qualitative approach using personal in-depth interviews. Eight participants (four female and four male) were asked to describe their perceptions and experience concerning sexuality, contraceptives, unwanted pregnancies and unsafe abortion. The result showed that culture and norms, misconceptions and gender based power in sexuality are factors that impact Sexual Reproductive Health among young people in Kisumu today. Unwanted pregnancy was described as a shame, a burden and a destroyed life which lead to many unsafely induced abortions. The findings indicate that youth interventions are important, such as engaging young men in unwanted pregnancy and thus unsafe abortions and to empower young women.

Textual Differences in Game Reviews Written by Men and Women

The aim of this essay is to examine the differences in language use between the genders in game reviews, to find whether there are differences in the use of the language depending on gender. Both sexist language and technical aspects are examined, the technical aspects of writing have been chosen from previous research about gendered differences in writing. The reviews are randomly chosen but the games are selected. There is an equal amount of games with male and female main characters, and the number of reviews is chosen according to the number of reviews written by females, as there are fewer of them, and thus easier to find a matching number of reviews written by males rather than vice versa. The reviews are then examined to find sexist language and differences. This essay finds that there is sexist language in the writing of both genders, such as marked language, but only when the main character of the game is female. Both genders tend to focus on the appearance of female characters and the characteristics of male characters, but there is no known previous research about male and female game characters to compare these results to. However, the technical differences remain consistent with previous research on the same subject, such as female reviewers using more pronouns than male reviewers, and male reviewers using fewer verbs than female reviewers.

Female senior managers in the Brazilian finance industry: a journey towards success

No nível global, a representação de líderes de sexo feminino nas empresas muitas vezes ainda se dá em números baixos em termos de percentagem. Particularmente em finanças, esses registros estão abaixo da média da indústria, e a forte concorrência e o ambiente de trabalho dominado pelos homens tornam difícil para as mulheres atingir o topo da pirâmide corporativa (Torres et al., 2013; OECD Better Life Index 2015). Isto pode ser devido a uma falta de equilíbrio trabalho-vida, diferentes estilos de liderança, as mulheres sendo intimidadas, ou a conformidade com estruturas familiares convencionalmente englobadas. No Brasil, os códigos de comportamento tradicionais são muito palpáveis na sociedade do país, embora esta também tenha se beneficiado de uma forte presença de movimentos feministas na segunda metade do século passado (Tate and Yang, 2015; Bowles et al. 2007; Niederle and Vesterlund, 2007). Nos últimos anos, o setor financeiro brasileiro tem crescido, oferecendo maiores oportunidades de emprego e desenvolvimento de carreira nas corporações nacionais e internacionais (Chiang et al., 2013; Bruschini, 2007). Esta dissertação aborda os desafios enfrentados por líderes de sexo feminino do mercado financeiro brasileiro e as suas trajetórias de carreira. Este objetivo será atingido por meio de uma análise de mídia social, focando nos anos de experiência de trabalho das mulheres analisadas, a posição atual delas e se elas têm filhos, bem como com 10 entrevistas semiestruturadas realizadas com executivas no setor financeiro no Brasil. Estas medidas irão abranger lacunas na literatura e consequentes recomendações para pesquisas futuras.

Description of a new species of skate of the genus Malacoraja Stehmann, 1970: the first species from the southwestern Atlantic Ocean, with notes on generic monophyly and composition (Chondrichthyes: Rajidae)

O primeiro registro para o Atlântico Sul ocidental de uma espécie do gênero Malacoraja Stehmann, 1970 é feita com base na descrição de Malacoraja obscura, espécie nova, proveniente do talude continental do Sudeste brasileiro dos estados do Espírito Santo e Rio de Janeiro em profundidades de 808-1105 m. A espécie nova é conhecida através de cinco exemplares e é distinta de seus congêneres pela sua coloração dorsal composta por numerosas manchas esbranquiçadas e pequenas na região do disco e nadadeiras pélvicas, por apresentar uma fileira irregular de espinhos ao longo da superfície dorsal mediana da cauda a qual persiste em espécimes maiores (desde a base da cauda até dois-terços do seu comprimento numa fêmea de 680 mm de comprimento total, CT) e uma região pequena desprovida de dentículos na base ventral da cauda (estendendo somente até a margem distal da nadadeira pélvica). Outros caracteres diagnósticos em combinação incluem a ausência de espinhos escapulares em indivíduos maiores, número elevado de fileiras dentárias (64/62 fileiras num macho subadulto de 505 mm de CT e 76/74 numa fêmea de 680 mm de CT) e de vértebras (27-28 Vtr, 68-75 Vprd), coloração ventral do disco uniformemente castanha escura, duas fenestras pós-ventrais na cintura escapular, fenestra pós-ventral posterior grande, forame magno circular e dois forames para a carótida interna na placa basal ventral do neurocrânio. Machos adultos não são conhecidos, porém uma descrição anatômica de M. obscura, sp. nov., é fornecida. Comparações são realizadas com todo o material conhecido de M. kreffti, com a literatura sobre M. senta e com material abundante de M. spinacidermis da África do Sul; M. obscura, sp. nov., assemelha-se mais a M. spinacidermis do Atlântico Sul oriental em esqueleto dérmico, coloração e tamanho. Malacoraja é monofilético devido à sua espinulação e apêndices rostrais conspícuos e é aparentemente composta por dois grupos de espécies, um para M. obscura e M. spinacidermis e outro para M. kreffti e M. senta, porém a elucidação das relações filogenéticas entre as espécies necessita de mais informações anatômicas, principalmente das duas últimas espécies.

Genetic associations between accumulated productivity, and reproductive and growth traits in Nelore cattle

The total meat yield in a beef cattle production cycle is economically very important and depends on the number of calves born per year or birth season, being directly related to reproductive potential. Accumulated Productivity (ACP) is an index that expresses a cow's capacity to give birth regularly at a young age and to wean animals of greater body weight. Using data from cattle participating in the "Program for Genetic Improvement of the Nelore Breed" (PMGRN - Nelore Brasil), bi-trait analyses were performed using the Restricted Maximum Likelihood method based on an ACP animal model and the following traits: age at first calving (AFC), female body weight adjusted for 365 (BW365) and 450 (BW450) days of age, and male scrotal circumference adjusted for 365 (SC365), 450 (SC450), 550 (SC550) and 730 (SC730) days of age. Median estimated ACP heritability was 0.19 and the genetic correlations with AFC, BW365, BW450, SC365, SC450, SC550 and SC730 were 0.33, 0.70, 0.65, 0.08, 0.07, 0.12 and 0.16, respectively. ACP increased and AFC decreased over time, revealing that the selection criteria genetically improved these traits. Selection based on ACP appears to favor the heaviest females at 365 and 450 days of age who showed better reproductive performance as regards AFC. Scrotal circumference was not genetically associated with ACP. (C) 2007 Elsevier B.V. All rights reserved.

Reproductive and behavioral aspects of red-winged tinamous (Rhynchotus rufescens) in groups with different sex ratios

The aim of this research study was to evaluate the reproductive performance of tinamous submitted to five different male:female ratios. The study was carried out with 72 birds in a randomized experimental design with 4 replications. Tinamous were housed in cages, using the ratios of one (1:1), two (2:1), three (3:1) and four (4:1) females per male, and also one male was housed with three females individually (3R:1), in a rotational system. Reproductive records of the breeding season from September 2004 to March 2005 were used. The reproductive traits studied were: number of eggs laid, fertility, and percentage of eggs damaged and cracked by pecking. Nonparametric analyses of these traits were performed using Kruskal-Wallis test. Two replications of treatments 1:1 and 4:1, and one of treatment 2:1 were video-taped for three days, 12 hours/day. The videotapes were sampled according to the scan method to fit an ethogram. Birds were also watched for one hour per day to study dominance and agonistic behavior. None of the reproductive traits was affected by mating sex ratio (p<0.05). Female dominance could be related to displacement behavior (r=1.00), and male sitting in immobility plus sitting in activity behaviors were related to lower number of damaged eggs (r=-0.90). Social dominance was indirectly determined by displacement behavior in the study situation. A large number of damaged eggs occurred in all treatments, thereby not allowing a clear conclusion on the best male:female ratio.

Feed restriction on performance and blood parameters of broilers fed diets with different sodium levels

The experiment was conducted to evaluate the effect of feed restriction and different sodium levels in the diet on the performance and hematological values (erythrocyte, hemoglobin, hematocrit, mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration and white blood cell) of broilers from 22 to 42 days of age. A completely randomized design was used in a 4 x 2 x 2 factorial (levels of sodium: 0.16%, 0.19%, 0.22% and 0.25%; with or without feed restriction; male and female), and two replicates of thirty broilers each. Sodium levels did not affect performance (p>0.05). Feed restriction resulted in increased feed intake and affected weight gain and feed conversion negatively (p<0.05). Better weight gain and feed conversion (p<0.05) were seen in male broilers. Hematological values were not affected by sodium levels, feed restriction or sex (p>0.05).

Determination and padronization of normal values of bone mineral density (BMD) of the acessory carpus bone in young Thoroughbred horse using optical densitometry in radiographic image

Em 12 fêmeas e 12 machos da raça Puro Sangue Inglês com idade média de 12 meses, avaliou-se os valores normais da densidade mineral óssea do carpo acessório em milímetros de alumínio (mmAl) até o momento do fechamento completo da epífise distal do rádio, por meio do método de densitometria óptica em imagens radiográficas. A avaliação foi realizada por meio de um programa computacional (software) especialmente desenvolvido para medida de densidade óptica em filmes de raios-X, o qual contém a imagem radiográfica do osso carpo acessório, região de partes moles adjacente ao carpo acessório e os degraus de uma escala de alumínio (phatom), que permitiu a medida de densidade mineral óssea, sendo esta a média aritmética da região de interesse determinada no osso carpo acessório correspondente ao valor em milímetros da escala. Os valores da densidade mineral óssea em mmAl do acessório do carpo em função da idade não apresentaram diferenças entre os sexos (p=0,86) permitindo que uma equação de reta fosse ajustada para ambos os sexos (densidade mineral óssea (DMO) mmAl = 3.109 + 0,056 x idade em meses), na faixa etária estudada.

Morphometric changes associated with sex and development in the Malpighian tubules of Aedes aegypti

The Malpighian tubules of Aedes aegypti showed significant differences in their diameters between male and female larvae, male and female pupae, male larvae and male adults and male pupae and male adults. in every case, female values were greater than in males. Measurements of mean nuclear areas of the principal and stellate cells from Malpighian tubules, taken in males and females during development, showed that this parameter in both types of cell was significantly greater in females than in male larvae, pupae and adult stages. In males, significant differences between developmental stages were observed only in comparison with the nuclear area of larvae and adults in the principal cells, but in females, every comparison between stages showed significant differences except between pupae and adults in stellate cells. The frequency distribution of nuclear area values, in development, for male stellate and principal cells, were mostly concentrated in the first seven classes among the 30 classes considered in every stage, while for females, the frequency dropped drastically in the same classes from larvae to pupae and adults, moving to classes of higher values. Considering the importance of Malpighian tubules in insect physiology, the meaning of the differences detected are discussed on the basis of different metabolic levels, between sexes and developmental stages.
