The Koundoum sheep breed in Niger: morpho-biometric study and description of the production system

The diffusion of highly productive breeds across developing countries goes along with a neglect of indigenous breeds, which are well suited to their environment but often show low yields. Thus, in Niger, the flock of Koundoum sheep are rapidly decreasing. The Koundoum is one of the few wool sheep breeds of Africa and shows important adaptive feature to its native environment, i.e. the humid pastures on the banks of the Niger River. To characterise the breed and to understand its production context, a survey has been conducted in 104 herds in four communes along the Niger River (Kollo, Tillabery, Say and Tera). Nine body measurements, including live weight, were taken on 180 adult sheep (101 females and 79 males). The herds varied from 2 to 60 heads, with a median size of eight animals and two thirds of the herds having less than 10 animals. Mainly fed on natural pastures, 85.6% of the herds received crop residues. Only natural mating was practiced. Veterinary care was restricted to anti-helminthic and some indigenous treatments. The frequent affiliation of breeders to professional unions appeared as favourable to the implementation of a collective conservation program. The Koundoum sheep were white or black coated, with the black colour being most frequent (75.6%). Wattles were present in both sexes at similar frequencies of around 14%. All biometric variables were significantly and positively correlated between them. The thoracic perimeter showed the best correlation with live weight in both males and females. Three variables were selected for live weight prediction: thoracic perimeter, height at withers and rump length. From the present study, it is expected that the in situ conservation of the Koundoum sheep will be highly problematic, due to lack of market opportunities for wool and the willingness of smallholders to get involved in pure Koundoum rearing.

La satisfacción del cliente bancario en Canadá: Diferencias entre canadienses e inmigrantes de la América Latina – Revisión y traducción

The measure of customer satisfaction level is one of the most important topics at present time in marketing science. In addition, its measure in the bank field takes force in view of the high level of competition inside it, even more so if the study counts “immigrants” as a variable in analysis, a much important variable in the demographic situation of Canada. Oliver (1980) proposes the model of “disconfirmation” to measure customer satisfaction level; this model confirms that the difference between customer perceived performance and customer expectations gives as result his satisfaction level (additional model). Presently multiple scales exist to evaluate and to quantify this satisfaction level, Parasuraman (1987) is the creator of the servqual scale, while Avkiran (1999) developed the bankserv scale in order to evaluate customer expectations and customer satisfaction level specifically inside the bank field; this scale was divided in four factors via factorial analysis. Literature suggests the presence of a relation between individual expectations and/or satisfaction level, and the individual tolerance level towards non-constructed situations (Newman, 2001). Hofstede (1980) developed five cultural dimensions worldwide; among these is the Uncertainty Avoidance Index (uai) that fits to the dimension directly related to customer expectations and customer satisfaction levels, since it measures the tolerance levels towards non-structured ituations. For this research I focused on the satisfaction model analysis proposed by Oliver (1980) based on Avkiran´s scale (1999), having the Latin American or Canadian origin as variables. The concept of Hofstede’s cultural differences leads me to propose two samples: 50 Canadian French speakers and 50 Latin American individuals (Canadian residents). Results demonstrate that in the Latin American group the expectations are in average higher that in the Canadian group, considering all four factors (Avkiran). Perceived performance and satisfaction level are higher in the Latin American group that in the Canadian group for “personal branch conduct” and “access to personalized services” factors, nevertheless, no statistically significant difference has been proved for “credibility” and “communication” factors. The expectations variable presents a mediating effect over the relation between variables uai (Latin American or Canadian origin) and satisfaction level. This effect is partial for “personal branch conduct” and perfect for “access to personalized services”.

Valores del índice cintura/cadera en población escolar de Bogotá, Colombia: Estudio

Objetivo: Determinar los valores del índice cintura/cadera (ICC) en una población escolar de Bogotá, Colombia, pertenecientes al estudio FUPRECOL. Métodos: Estudio descriptivo y transversal, realizado en 3.005 niños y 2.916 adolescentes de entre 9 y 17,9 años de edad, pertenecientes a 24 instituciones educativas oficiales de Bogotá, Colombia. Se tomaron medidas de peso, talla, circunferencia de cintura, circunferencia de cadera. El estado de maduración sexual se recogió por auto-reporte. Se calcularon los percentiles (P3, P10, P25, P50, P75, P90 y P97) según sexo y edad y se realizó una comparación entre los valores del ICC observados con estándares internacionales. Resultados: De la población general (n=5.921), el 57,0% eran mujeres (promedio de edad 12,7 ± 2,3 años). En todas las edades el ICC fue mayor en los varones que en las mujeres, observándose un descenso en la media de los valores obtenidos desde los 9 hasta los 17,9 años. En varones, los valores del ICC mayores del P90 (asociados a riesgo cardiovascular) estuvieron en el rango 0,87 y 0,93 y en las mujeres entre 0,85 y 0,89. Al comparar los resultados de este estudio, por grupos de edad y sexo, con trabajos internacionales de niños y adolescentes de Europa, Suramérica, Asia y África, se observa que los valores del ICC fueron menores en este estudio en ambos sexos, con excepción de los escolares originarios de Grecia y Venezuela. Conclusiones: Se presentan percentiles del ICC según edad y sexo que podrán ser usados de referencia en la evaluación del estado nutricional y en la predicción del riesgo cardiovascular desde edades tempranas en población de Bogotá, Colombia.

Percentiles de circunferencia de cintura en escolares de Bogotá, Colombia Estudio FUPRECOL

Objetivo: Determinar la distribución por percentiles de la circunferencia de cintura en una población escolar de Bogotá, Colombia, pertenecientes al estudio FUPRECOL. Métodos: Estudio transversal, realizado en 3.005 niños y 2.916 adolescentes de entre 9 y 17,9 años de edad, de Bogotá, Colombia. Se tomaron medidas de peso, talla, circunferencia de cintura, circunferencia de cadera y estado de maduración sexual por auto-reporte. Se calcularon los percentiles (P3, P10, P25, P50, P75, P90 y P97) y curvas centiles según sexo y edad. Se realizó una comparación entre los valores de la circunferencia de cintura observados con estándares internacionales. Resultados: De la población general (n=5.921), el 57,0% eran chicas (promedio de edad 12,7±2,3 años). En la mayoría de los grupos etáreos la circunferencia de cintura de las chicas fue inferior a la de los chicos. El aumento entre el P50-P97 de la circunferencia de cintura , por edad, fue mínimo de 15,7 cm en chicos de 9-9.9 años y de 16,0 cm en las chicas de 11-11.9 años. Al comparar los resultados de este estudio, por grupos de edad y sexo, con trabajos internacionales de niños y adolescentes, el P50 fue inferior al reportado en Perú e Inglaterra a excepción de los trabajos de la India, Venezuela (Mérida), Estados Unidos y España. Conclusiones: Se presentan percentiles de la circunferencia de cintura según edad y sexo que podrán ser usados de referencia en la evaluación del estado nutricional y en la predicción del riesgo cardiovascular desde edades tempranas.

Actitudes hacia el VIH/SIDA, el cáncer y la enfermedad de Alzheimer

Esta revisión de la literatura tuvo como objetivo describir las actitudes hacia el VIH/SIDA, el cáncer y la Enfermedad de Alzheimer desde el modelo tripartito. Se revisaron 109 artículos publicados entre 2005 y 2015 en algunas bases de datos especializadas y herramientas de análisis de impacto. También se incluyeron fuentes secundarias ampliándose la búsqueda a los últimos 20 años (1995-2015). Los resultados mostraron que la mayoría de los estudios realizados sobre las actitudes hacia estas tres enfermedades son de tipo cuantitativo y la información se analizó con base en los componentes del modelo tripartito. Algunos aspectos sociodemográficos como el sexo y la edad están asociados con las actitudes hacia las tres enfermedades y predominan las creencias erróneas sobre ellas respecto a sus causas, curso y tratamiento. También predominan actitudes negativas hacia las tres enfermedades y las conductas e intenciones conductuales son diversas hacia cada una de ellas. No se hallaron antecedentes empíricos del estudio de la estructura de las actitudes propuesta por el modelo tripartito hacia las tres enfermedades. La Salud Pública ha liderado la investigación con base en el modelo de conocimientos, actitudes y prácticas propuesto por la OMS.

Intersections and differentiations: a corpus-assisted discourse study of gender representations in the British press before, during and after the London Olympics 2012

This study examines the impact of a global sports event on gender representations in media reporting. Whereas previous research on gender, sport and media has been mainly concerned with sports events in the North American or Australian context, this study investigates the British media reporting before, during and after the London Olympics 2012. Our study follows the approach of Corpus-Assisted Discourse Studies (CADS) and uses both quantitative and qualitative research procedures. The results reveal more balanced gender representations during the London Olympics in that the ‘regular’ biased associations were supressed in favour of positive references to female achievements. However, little carry-though of the ‘gains’ was noted. Also, this study shows that the positive associations intersected with national sentiments and were used to celebrate the nation-state. At the same time, some subtle resistance was observed to accepting as ‘truly’ British the non-white athletes and those not born in Britain.

Preconceito e estereótipos relativos a cor, sexo e status

Esta pesquisa investiga os estereótipos positivos e/ou negativos, quando considerados como variáveis de cor, sexo status. O instrumento utilizado consistiu de oito desenhos estímulos, sendo quatro homens e quatro mulheres: homem branco de status alto (HBR), homem negro de status alto (HNR), homem branco de status baixo (HBP), homem negro de status baixo (HNP), mulher branca de status alto (MBR), mulher negra de status alto (MNR), mulher branca de status baixo (MBP) e mulher negra de status baixo (MNP), distribuídos equitativamente pela amostra, em um questionário com nove itens objetivos para pedir sobre o desenho estímulo, a distância social, a escolaridade, a posição hierárquica no trabalho, a ocupação desempenhada pelo estímulo e por seus pais para averiguar a mobilidade social, a classe sócio econômica e um item em aberto para apreender como a amostra percebe os estímulos. A amostra foi composta de 930 sujeitos: 482 de cor epidérmica e atributos físicos (boca, cabelos e sujeitos nariz) brancos e 448 sujeitos negros de cor epidérmica e atributos físicos negros, ou cor epidérmica branca e atributos físicos negros, ou cor epidérmica negra e atributos físicos brancos, atribuídos pelo experimentador. Estes mesmos sujeitos se auto classificaram como sendo 602 sujeitos "brancos" e 328 sujeitos negros. A hipótese básica testada foi: "Há estereótipos positivos e negativos relativos à cor, sexo e status." O único item que rejeitou a hip6tese nula básica, foi aquele sobre a ocupação desempenhada pelas figuras-estímulos onde as amostras brancas, atribuída pelo experimentador e autoclasificada, e negra autoclassificada corno branca, rejeitaram-na quanto às variáveis de sexo e status, sugerindo que os estereótipos aparecem de acordo com as ocupações atribuídas, quanto ao sexo e status das figuras-estímulos. As amostras negras, atribuída pelo experimentador e autoclassificada, rejeitaram-nas três variáveis, mostrando a influência da cor, sexo e status, separadamente, sobre o estereótipo medido através da ocupação atribuída aos estímulos, além da interação cor X status, sugerindo também a presença do estereótipo ocupacional, quando a cor se associa ao status dos desenhos. A amostra negra, atribuída pelo experimentador, rejeita-a, ainda, na interação cor X sexo X status parecendo existir discriminação quanto as ocupações dadas aos estímulas, quando estas três variáveis se associam. As amostras brancas, atribuída pelo experimentador e autoclassificada, apresentaram respostas ambíguas na maioria dos itens. As amostras negras, atribuída pelo experimentador e autoclassificada, não mostraram diferenças significativas entre as respostas, em parte dos itens. O critério ABIPEME expressou que ambas as amostras branca e negra, atribuídas pelo experimentador, apresentaram alta escolaridade e bom nível sócio-econômico. O número de mulheres era superior ao número de homens, embora homens e mulheres se equivalessem em ambas as amostras, o que sugere que mulheres brancas e negras e homens negros se com portaram de acordo com os valores culturais e dominantes, demonstrando auto-desvalorização e baixa auto-estima.

Autoeficácia, características sociodemográficas e capacitação profissional: um estudo com servidores de uma Universidade Federal

Self-efficacy, the construct developed by Albert Bandura in 1977 and widely studied around the world, means the individual's belief in his own capacity to successfully perform a certain activity. This study aims to determine the degree of association between sociodemographic characteristics and professional training to the levels of Self-Efficacy at Work (SEW) of the Administrative Assistants in a federal university. This is a descriptive research submitted to and approved by the Ethics Committee of UFRN. The method of data analysis, in quantitative nature, was accomplished with the aid of the statistical programs R and Minitab. The instrument used in research was a sociodemographic data questionnaire, variables of professional training and the General Perception of Self-efficacy Scale (GPSES), applied to the sample by 289 Assistants in Administration. Statistical techniques for data analysis were descriptive statistics, cluster analysis, reliability test (Cronbach's alpha), and test of significance (Pearson). Results show a sociodemographic profile of Assistants in Administration of UFRN with well-distributed characteristics, with 48.4% men and 51.6% female; 59.9% of them were aged over 40 years, married (49.3%), color or race white (58%) and Catholics (67.8%); families are composed of up to four people (75.8%) with children (59.4%) of all age groups; the occupation of the mothers of these professionals is mostly housewives (51.6%) with high school education up to parents (72%) and mothers (75.8%). Assistants in Administration have high levels of professional training, most of them composed two groups of servers: the former, recently hired public servants (30.7%) and another with long service (59%), the majority enter young in career and it stays until retirement, 72.4% of these professionals have training above the minimum requirement for the job. The analysis of SEW levels shows medium to high levels for 72% of assistants in administration; low SEWclassified people have shown a high average of 2.7, considered close to the overall mean presented in other studies, which is 2.9. The cluster analysis has allowed us to say that the characteristics of the three groups (Low, Medium and High SEW) are similar and can be found in the three levels of SEW representatives with all the characteristics investigated. The results indicate no association between the sociodemographic variables and professional training to the levels of self-efficacy at work of Assistants in Administration of UFRN, except for the variable color or race. However, due to the small number of people who declared themselves in color or black race (4% of the sample), this result can be interpreted as mere coincidence or the black people addressed in this study have provided a sense of efficacy higher than white and brown ones. The study has corroborated other studies and highlighted the subjectivity of the self-efficacy construct. They are needed more researches, especially with public servants for the continuity and expansion of studies on the subject, making it possible to compare and confirm the results

Complete staining of nerve fiber and myoneural junctions with acetylthiocholine and silver

We describe a combined stain for simultaneous demonstration of the preterminal axons and cholinesterase activity at myoneural junctions of mammalian muscles. This technique employs acetylthiocholine iodide as the substrate for cholinesterase activity and silver nitrate impregnation of preterminal axons. The procedure is rapid, simple and uses fresh muscles. Intramuscular nerves, preterminal axons and myoneural junctions are stained simultaneously brown or black with minimal background staining of connective tissue and muscle fibers.

Clinical and histologic features of botryoid odontogenic cyst: A case report

Introduction. The lateral periodontal cyst, as the name implies, occurs on a lateral periodontal location and is of developmental origin, arising from cystic degeneration of clear cells of the dental lamina. A botryoid odontogenic cyst is considered to be a rare multilocular variant of a lateral periodontal cyst. Case presentation. We report the clinical and histopathologic features of a rare case of botryoid odontogenic cyst found in an edentulous area corresponding to the right lower canine of a 64-year-old African-American woman. A multilocular radiolucency was observed, and surgical removal of the lesion revealed a nodule of rubber-like consistency measuring about 1.5 cm in diameter. Cross-sectioning of the nodule showed that it consisted of various cystic compartments. Histologically, various voluminous periodic acid-Schiff-negative clear cells randomly distributed throughout the cystic epithelium were observed, as well as cell layers showing thickenings generally formed by oval, sometimes entangled plaques. The capsule consisted of fibrous connective tissue and showed rare and discrete foci of a perivascular mononuclear inflammatory infiltrate and reactive bone-tissue fragments. The final diagnosis was botryoid odontogenic cyst. Conclusion: We provide data that allow the reader to establish the differences between botryoid odontogenic cyst, glandular odontogenic cyst, and lateral periodontal cyst, helping with the differential diagnosis. The reader will have the opportunity to review botryoid odontogenic cyst clinical and histopathologic features, including treatment. © 2010 Farina et al; licensee BioMed Central Ltd.
