Economic analysis of the traditional Beldi Chicken value chain in Morocco
No full textPoultry meat production in Morocco has experienced a considerable growth over the past two decades. Indeed, the poultry sector has a significant economic weight in Moroccan agriculture with 23.3 million days of labor and 9.9 billion dirhams in added value in 2019. However, there is a huge gap between the traditional and industrial poultry sectors in terms of production, processing, promotion and support. This work focuses on the traditional beldi chicken value chain in the Morocco. Its general objective is to contribute to the detailed economic analysis of the “Beldi” chicken value chain. In addition, this study will analyze the main factors that determine the income from traditional chicken production. We note that the traditional Beldi chicken sector is characterized by a high degree of informality, which can make it difficult to track supply and demand and ensure fair prices for all actors of the value chain. It represents an important source of income for small farmers and the most deprived families and contributes to reducing poverty.

Etude rétrospective des systèmes d’élevage et dominantes pathologiques du poulet traditionnel «beldi» au Maroc
No full textThis article relates the works carried out on traditional poultry farming in Morocco, by addressing the multiple socioeconomic, food, cultural and ecological importance of poultry production systems, on a small scale in the fight against poverty and food insecurity among vulnerable rural populations. After having raised the phenotypic characteristics of the country chicken « beldi »population and their zootechnical performances, this work describes the different aspects of the farming system, identifies the main constraints which slow down the development of this activity and places particular emphasis on the dominant pathological aspects of the beldi chicken.

MR DIFFUSION-WEIGHTED IMAGING IN THE DELINEATION OF TREATMENT VOLUME OF HIGH-GRADE GLIOMA: PRELIMINARY RESULTS OF A PROSPECTIVE TRIAL
No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Rentabilidad en la empresa Beldi Internacional S.A.C. San Martín de Porres, 2014
No full textLa presente investigación denominada Rentabilidad en la empresa Beldi Internacional S.A.C.,
San Martín de Porres, 2014, tuvo como finalidad determinar el nivel de rentabilidad en la
empresa.
Profundizando la investigación se determinó que no se operan las medidas para efectuar un
buen análisis de los estados financieros y los indicadores de rentabilidad, esto se puede
deliberar según la teoría de Oriol que menciona la rentabilidad económica y rentabilidad
financiera como estudio del rendimiento. El tipo de investigación es de nivel descriptivo.
La investigación se desarrolló bajo un diseño no experimental descriptivo- simple , como
muestra se realizó a 15 trabajadores del área de gerencia, contabilidad y ventas en la empresa,
la muestra fue no probabilística e intencionada. La técnica utilizada para la recopilación de los
datos fue la encuesta a través del cuestionarios graduado en escala nominal dicotómica para
la variable Rentabilidad, que consta de 14 preguntas, previamente validados donde se
demostró la validez y confiabilidad, mediante la técnica de opinión de expertos y kuder
Richardson (KR20).
En la presente investigación se halló que los trabajadores de la empresa Beldi Internacional
S.A.C. del distrito de San Martin de Porres, 2014 presentan un 52% en relación a la rentabilidad
lo cual determina un nivel bajo, por lo tanto se llegó a la conclusión que se debe aplicar
indicadores de rentabilidad que permita a la empresa saber la situación económica y
financiera en la que encuentra al término de sus obligaciones, y el superávit que se ha
obtenido, ya que esto es beneficioso para los accionistas
Stereotactic ablative radiotherapy for oligometastatic prostate cancer
No full textBackground: The present study assessed clinical outcomes of stereotactic body radiotherapy (SBRT) in oligometastatic prostate cancer patients. Materials and methods: Between 2017 and 2020, 37 lesions (12 osseous and 25 nodal targets) detected with conventional and/or functional imaging, were treated in 29 patients (pts), in different clinical settings: de novo oligometastatic (2 pts), oligorecurrent castration-sensitive (19 pts), castration-resistant (6 pts) prostate cancers and oligoprogressive disease during systemic therapy (2 pts). SBRT was delivered with volumetric modulated arc therapy up to a total dose of 21 Gy given in 3 fractions for bone and 30 Gy in 5 fractions for nodal metastases. A total of 34% of pts received hormonal therapy. We evaluated biochemical control [prostate serum antigen (PSA) increase grade 2 was reported. Conclusions: SBRT for oligometastatic prostate cancer offers a good biochemical/local control and tangible delay of hormone/systemic therapy without major toxicities
