This study was aimed to find out the growth rate of Nile Tilapia (Oreochromis niloticus) cultured with biofloc technology, and to understand the dynamic of several water quality parameters during culture period. This experiment was conducted in the Laboratory of Aquaculture Technology, FPIK, UNSRAT. Several substances were added to stimulate the development of biofloc, which were: 0,3 mL of EM-4 containing probiotic-bacteria Lactobacillus casei dan Saccharomyces cerevisiae.; 15 mL of mollases; 0,5 g of yeast commonly used to ferment soybean ; 12 g of dolomite. 60 seeds of nile tilapia, with an individual weight of 6 g, were stocked in each container. Fish were fed at a dose of 3% of the total biomass/day at the first week, and the dose was decreased down to 1% of the total biomass per day afterwards. Fish were weighed at day-1, day-15 and day-30. The change of water color and the density of the floc was consistently evaluated using imhoff-cone. The initial weight of the tested individual fish were 6,00 g. After 15 days, the weight was increased to 7,37g, and at the end of the experiment the individual fish weighed 11,47 g. Hence, the absolut growth of the tested fish was 5,47g, the specific growth rate was 91% and the daily growth rate was 2,11%. The density of flok reached 9,5 mL/L at the beginning of the second week, which was categorized as very high density. The density of floc then was decreased to 4 mL/L. The density of the floc was maintained around 5 mL/L during the experiment. The temperature of the medium was at the range of 26-300C. The level of ammonia was 0,03mg/L and the level of nitrite fluctuated between 0,15-3mg/L, which is normal and safe for biofloc system. The level of nitrate was 4-55 mg/L, which was quite high for biofloc system but not harmful for fish. Keywords: Biofloc, Nile-Tilapia, growth, floc-density

Published: July 2019

The aim of the research was to find out the growth rate of the marine lobster, Panulirus versicolor, fed different types of diets. The experiment was conducted at the Laboratory of Aquaculture Technology, Faculty of Fisheries and Marine Sciences, Sam Ratulangi University. The experiment was set up in 3 treatments, which were three different types of diet: treatment-A: papaya leaves, treatment-B: coconut flesh, treatment-C: skipjack-fish flesh. Each treatment was triplicated. The tested lobsters were collected from the marine waters of the Likupang village, North Minahasa Regency. The tested lobsters were weighed at the beginning, at the end of the experiment, and at the interval of 14 days during the experiment period. The data of the body weight change were statistically analysed using the analysis of the homogeneity of the 3 different linear regression coefficients, between time (X) and the body weight of the lobsters (Y) fed different types of feed, at the confidence test level a = 5% and 1%. The results show that the body weight of the tested lobsters fed skipjack-fish flesh increased 4 grams after 30 days of the rearing period. The body weight of the tested lobsters fed papaya leaves decreased 11 g, and the body weight of those fed coconut flesh decreased 3 g after 30 days of the rearing period. The result of the regression analysis shows, the assumption that the 3 regression coefficients are homogenous is rejected. In other words, there is a significant difference among the growth rates of the tested lobsters fed different type of diets. Compared to skipjack-fish flesh, the papaya leaves and coconut flesh significantly slow down the level of the water quality degradation during experiment period.Keywords: diets, growth, marine-lobster

The development of the digital teaching competence from a sociocultural approach
Authors: Colás-Bravo-Bravo Pilar , Conde-Jiménez Jesús , Reyes-de-Cózar Salvador 
Published: July 2019

Many Nowadays, digital teaching competence transcends the individual training of teachers in ICT. The European framework DigCompEdu, highlights that teachers must train students in the application of digital technologies in a critical and responsible way, in terms of information, communication, content generation, wellbeing and problem solving. Despite the good intentions to systematize a common model of development of digital competence, it is detected that the proposals lack a pedagogical approach that serves as a theoretical framework for them. This paper proposes a development model of the digital teaching competence based on the sociocultural approach through four constructs: Command, Preference, Reintegration and Appropriation. For this study, an ad hoc scale is created to record the digital teaching competence through the development of this in their students and empirical evidences are provided. A survey type design is proposed. The sample consists of 1,881 students of compulsory education in Andalusia (Spain). SPSS is used to analyse data. The average general results for each of the dimensions studied reveal a medium level of development of digital competence. It is concluded that there is still too much to be done in terms of teacher training in ICT, being necessary to provide them strategies for the development of this in their students.En la actualidad, la competencia digital docente trasciende de la formación individual del profesorado en materia TIC. El marco europeo DigCompEdu incide en que el profesorado tiene que capacitar al alumnado en la aplicación de las tecnologías digitales de forma crítica y responsable en cuanto a información, comunicación, generación de contenido, bienestar y resolución de problemas. Pese a las buenas intenciones para sistematizar un modelo común de desarrollo de la competencia digital, se detecta que las propuestas carecen de un enfoque pedagógico que sirva de base teórica de los mismos. Este trabajo propone un modelo de desarrollo de la competencia digital docente basado en el enfoque sociocultural mediante cuatro constructos: Dominio, Preferencia, Reintegración y Apropiación. Para ello, se elaboró una escala ad hoc para registrar la competencia digital docente a través del desarrollo de esta en sus estudiantes, aportando evidencias empíricas. Se plantea un diseño de tipo cuestionario. La muestra se compone de 1.881 estudiantes de educación obligatoria de Andalucía. Para el análisis de datos se utilizó SPSS. Los resultados promedios generales por cada una de las dimensiones estudiadas revelan un nivel medio de desarrollo de la competencia digital. Se concluye que aún existe mucho por hacer en cuanto a la formación del profesorado en materia TIC, siendo necesario facilitarles estrategias para el desarrollo de esta en sus estudiantes.
Enfiler les gants de la respectabilité
Authors: Oualhaci Akim 
Published: July 2019

À partir d’une enquête ethnographique dans deux salles de boxe situées dans des quartiers populaires en France et aux États-Unis, cet article montre en quoi la socialisation à la boxe relève d’une transmission de capital culturel. La proximité sociale entre entraîneurs et boxeurs facilite le travail de socialisation de ces derniers qui s’engagent dans une transformation de soi indissociablement corporelle et culturelle. En retour, l’accumulation de capital culturel produit des effets différenciés sur les espaces sociaux étudiés. L’ethnographie comparée met en lumière des points de convergence et de divergence dans les principes constitutifs de la stratification sociale des jeunesses populaires racisées en France et aux États-Unis. L’analyse du processus d’accumulation du capital culturel montre en quoi les destins sociaux possibles divergent pour les boxeurs aux États-Unis et en France : pour les premiers, ce processus ouvre davantage d’espoir de mobilité sociale et résidentielle ; pour les seconds, il donne plus accès à des statuts locaux.
L’empire de la notation (France, XIX e siècle)
Authors: Karila-Cohen Pierre , Le Bihan Jean 
Published: July 2019

Dans ce deuxième volet du triptyque consacré à la notation des fonctionnaires en France au xix e siècle, il s’agit d’explorer l’économie interne des feuilles de notes. Dans une première partie, les rubriques de ces feuilles sont analysées et l’on constate que les renseignements demandés varient peu d’une branche de l’État à l’autre. Deux hypothèses interprétatives, en partie valables, sont ensuite examinées pour comprendre à quoi servait la notation : la disciplinarisation des agents et la rationalisation de leur gestion. Enfin, on montre que ces feuilles, en indiquant aux fonctionnaires les rôles qu’ils devaient remplir, constituèrent surtout un outil essentiel de l’étatisation dans la France du xix e siècle.
La crise d’adolescence est-elle universelle ?
Authors: Figueiredo Cristina 
Published: July 2019

Dans un congrès de la Société française de psychiatrie en mai 2000, dont la thématique était « crises et pédopsychiatrie », Françoise Héritier a mené une discussion sur le passage à l’âge adulte, moment clé où les représentations sociales et culturelles sont assignées, et incorporées, avec plus ou moins de violence. Le corps adolescent est probablement le lieu à la fois le plus explicite, par sa transformation radicalement visible, et le plus implicite, par les vécus non exprimés, des changements de représentations intériorisés, ou rejetés, dans le silence ou le fracas. Le corps permet donc l’observation du changement et l’éventuelle expression de ce qui est communément nommé « la crise d’adolescence ». Il s’agit dans cette réflexion autour de la pensée de Françoise Héritier, sur la symbolique du corps et la manière dont se construit la dichotomie du masculin et du féminin, de comprendre la réalité des tensions propres à cette phase de la vie et comment elles sont appréhendées dans plusieurs sociétés du monde.
Inceste gémellaire, deuil et mélancolie créatrice
Authors: Fortier Corinne 
Published: July 2019

Suite à mes recherches sur la transidentité et en dialogue avec l’inceste « des deux sœurs et de leur mère » de l’anthropologue Françoise Héritier, je propose ici le concept d’« inceste gémellaire » qui peut s’appliquer indépendamment du sexe et de la parenté tant qu’il implique une relation réelle ou fantasmée de « gémellité ». La transidentité fait re-naître fantasmatiquement un proche, parti ou mort, avec lequel l’individu entretenait une relation de type « gémellaire », recréant cette fusion originelle et incestueuse de manière mélancolique comme le fit l’artiste Pierre Molinier avec sa sœur. L’écriture peut aussi être un moyen de « ressusciter » le double perdu au lieu de l’incarner dans sa chair ainsi que le montre l’œuvre littéraire de la romancière Annie Ernaux écrite pour sa sœur qu’elle n’a jamais connue.
La clinique est morte, vive la clinique !
Authors: Corteel Mathieu 
Published: July 2019

La médecine clinique fut longtemps considérée comme morte. On la croyait disparue dans l’émergence technologique des I.A. et des big data . Mais ses meurtriers ont oublié que la clinique est une pratique théorique qui se différencie dans le regard et la décision de chaque médecin comme de chaque patient. La clinique ne s’est-elle pas dès lors transformée au gré du temps et des technologies ? C’est ce que l’article interroge. Mais dès lors qu’elle renaît, quelles pourraient être ses perspectives d’avenir ? Produisant des observations, des décisions thérapeutiques et des résultats de traitement, la clinique fournit une masse de données au système de santé. Elle représente une source inestimable de big data pour la médecine. Elle ouvre la voie pour intégrer les I.A. à la décision. Mais c’est l’autogestion de ces données par la relation clinique qui doit pouvoir dessiner les perspectives éthiques et politiques d’une médecine garantissant les biens communs dans l’avancée technologique actuelle.
Le hasard clinique ou la crise de la rationalité médicale
Authors: Corteel Mathieu 
Published: July 2019

L’application médicale de la loi des grands nombres a longtemps effrayé les cliniciens pour sa potentialité à réduire le médecin à n’être « qu’une machine arithmétique » et le patient à n’être « qu’un individu pathologique moyen ». Les enjeux de la prise de décision clinique, qui répondent depuis le xix e siècle à une double exigence de soin et de connaissance ont ainsi engendré une crise de la rationalité médicale. La médecine clinique, en s’efforçant de rendre le hasard positif, a ainsi opposé l’art à la science. En considérant ce conflit dans l’histoire longue de la médecine, cet article en vient à questionner la numérisation de la décision médicale effectuée au moyen de l’I.A. et des big data , d’un point de vue épistémologique comme éthique.
