Devising a didactic instrument to improve the teaching of text comprehension

Processes for devising a didactic instrument aiming to improve the continuous teaching of the reading skill with 9 to 14 year old pupils are presented in this article. These processes rely on a threefold analysis of the text comprehension activity, of the diffi culties of pupils and the practices of teachers. The instrument which is tested out gives a central place to the teaching of the procedures which underlie efficient comprehension, to pupils’ becoming aware of them and to their self-regulation in text reading situations.

Los talleres de lectura en el ciclo 3 de la escuela primaria : ¿ dispositivo pertinente de ayuda a la comprension de los textos ?

Los programas de la escuela primaria de febrero de 2002 preven en el ciclo 3 la puesta a punto de talleres de lectura. Estos programas siguen siendo muy evasivos sobre la forma y el contenido de estos talleres. El estudio comenzado a partir de 2003 se ha basado en un primer momento en lo que a priori podrían ser los talleres de lectura (adecuación a las difi cultades/talleres de lectura). En una etapa sucesiva, a partir de este trabajo inicial, una primera experimentación se ha llevado a cabo en una clase de CM2 (evaluación de los alumnos, realización de algunos talleres). El análisis del conjunto de los datos recogidos hasta entonces ha permitido poner en evidencia el interés de algunas nociones (nociones de «escenario(s)» o de «circuitos retrospectivos» y de «procesos de organización»). Estas nociones están todavía elaborándose. Un segundo estudio que se iniciará en septiembre de 2006, se propone profundizarlas y probarlas a través de la realización de talleres de lectura en el conjunto del ciclo 3 del mismo colegio. Los resultados presentados se han de considerar como provisionales

In der Situation des kulturellen Vermittlers schaffen es Schüler mit schweren Schulschwierigkeiten Kompetenzen im Vorlesen zu erwerben

Folgender Beitrag berichtet über die Vorlesung von Alben von Sonderschülern vor Kleinen aus dem Kindergarten. (d.h vor 5 jährigen Schülern aus der sogenannten “école maternelle”). Der Autor untersucht wie die Schüler in der Situation des kulturellen Vermittlers ihre eigenen Lesefertigkeiten entwickeln. Und zwar Fähigkeiten : als Leser/Entzifferer ; im Bereich der Beherrschung der Zeichensetzung und somit der schriftlichen Wortfolgen ; im Gebrauch verschiedener Sprachtöne je nach der Situation ; im Bereich des Leseverständnises. Es handelt sich darum, pädagogische Anpassungssituationen zu erdenken, die die Akulturation fördern sowie die Integration in der schulischen Struktur in der Perspektive von der Fertigkeitenentwicklung der Vorlesekompetenzen. Ein Videofi lm über die verschiedenen Vorlesungen wird gedreht. Er zielt auf eine von dem Vorleser selbst am Ende der Vorlesungssequenzen durchgeführte Analyse der erworbeben Fertigkeiten und der noch unerworbenen individuellen Fähigkeiten Diese Rücksichtnahme versucht bei ihnen eine Beziehung zu den schulischen schriftlichen Fertigkeiten zu schaffen, wobei es noch Interaktionen mit ihrem eher praktischen und mündlichen kulturellen Modell gibt

Local interstellar spectra (LIS) of primary cosmic ray (CR) nuclei, such as helium, oxygen, and mostly primary carbon are derived for the rigidity range from 10 MV to ∼200 TV using the most recent experimental results combined with the state-of-the-art models for CR propagation in the Galaxy and in the heliosphere. Two propagation packages, GALPROP and HelMod, are combined into a single framework that is used to reproduce direct measurements of CR species at different modulation levels, and at both polarities of the solar magnetic field. The developed iterative maximum-likelihood method uses GALPROP-predicted LIS as input to HelMod, which provides the modulated spectra for specific time periods of the selected experiments for model–data comparison. The interstellar and heliospheric propagation parameters derived in this study are consistent with our prior analyses using the same methodology for propagation of CR protons, helium, antiprotons, and electrons. The resulting LIS accommodate a variety of measurements made in the local interstellar space (Voyager 1) and deep inside the heliosphere at low (ACE/CRIS, HEAO-3) and high energies (PAMELA, AMS-02).

Este ensaio tem como objetivo principal entender a importância das TICs (Tecnologias da Informação e Comunicação) e dos controles econômicos e financeiros na visão dos agricultores familiares do Vale do Caí- RS, bem como as mudanças socioeconômicas ocorridas principalmente após 1970 e seus reflexos para o meio rural. Foi realizado um levantamento empírico junto ao Projeto “O uso e a apropriação das TICs pela agricultura familiar no Vale do Caí-RS” para 10 famílias de agricultores familiares visando entender a percepção desses agricultores sobre a temática. O estudo apresenta a discussão sobre desenvolvimento rural e sobre a importância das TICs. Também apresenta os procedimentos metodológicos, bem como, sugestões iniciais de controles econômicos e financeiros aplicados à gestão rural. Concluiu-se que apesar de não se pretender generalizar pode-se afirmar preliminarmente que os agricultores têm influência típica dos sistemas capitalistas monoprodutores e carência de orientação sobre a utilização das ferramentas citadas para melhoria na gestão da propriedade rural, entendendo, ainda que a dimensão econômica e financeira é apenas uma entre várias questões socioambientais importantes para o desenvolvimento rural.
A new Notomastus (Annelida, Capitellidae) species from Korean waters, with genetic comparison based on three gene markers
Authors: Jeong Man-Ki , Soh Ho Young , Wi Jin Hee , Suh Hae-Lip
Published: May 2018

Notomastuskoreanussp. n., collected from the sublittoral muddy bottom of Korean waters, is described as a new species. The Korean new species closely resembles N.torquatus Hutchings & Rainer, 1979 in the chaetal arrangement and the details of abdominal segments, but differs in the position of genital pores and the absence of eyes. DNA sequences (mtCOI, 16S rRNA, and histone H3) of the new species were compared with all the available sequences of Notomastus species in the GenBank database. Three genes showed significant genetic differences between the new species and its congeners (COI: 51.2%, 16S: 38.1–47.3%, H3: 3.7–9.3%). This study also includes a comprehensive comparison of the new Korean Notomastus species with its most closely similar species, based on the morphological and genetic results.
Ce que la participation fait à l'action publique
Authors: Boisseuil Clément
Published: May 2018

Résumé À partir de l'étude du projet de rénovation des logements sociaux de Lathrop dans la ville de Chicago (Illinois), cet article analyse les effets de la participation des publics-bénéficiaires sur la mise en œuvre de l'action publique. Les habitants de ce quartier se sont opposés au projet pour lequel ils ont été sollicités. Leur usage des dispositifs participatifs a entraîné la constitution d'un mouvement protestataire ayant abouti au blocage du projet pendant plusieurs années. Les processus participatifs peuvent donc échapper aux acteurs publics ou privés qui en ont la responsabilité. Il apparaît que la participation a ouvert une fenêtre d'opportunité pour la contestation et que ses outils ont constitué autant de structures mobilisatrices à partir desquelles les citoyens-bénéficiaires se sont organisés et ont cadré leurs revendications. Pourtant, l'article met aussi en avant la complexe adaptation des programmes publics en réponse à l'inclusion des publics-cibles. Il conclut que les limites de la participation se situent peut-être davantage dans l'incapacité des acteurs publics à apprendre de ces processus plutôt que dans la manipulation des dispositifs participatifs ou des conflits qui en émergent.
L’assèchement des choix. Pluralisme et écologie
Authors: Villalba Bruno
Published: May 2018

La démocratie est le régime politique qui légitime la liberté de chacun à choisir les conditions politiques et sociales de son existence. Le pluralisme, dans sa dimension procédurale – et notamment à travers le vote– met en scène la diversité des choix et des trajectoires politiques possibles pour un peuple. Il organise l’expression et la compétition des choix politiques ; il met en place une conception de la citoyenneté qui s’élabore sur des choix illimités dans le temps et dans un monde politique d’abondance, sans limites . Mais confronté aux finitudes écologiques, il se trouve face à la contraction des options possibles, ce qui produit un assèchement des choix offerts par la démocratie. Le pluralisme actuel doit alors imaginer des adaptations temporelles et des procédures de limitation susceptibles d’ajuster l’idéal d’émancipation de la démocratie au contexte limité de son assise matérielle.
Le rire comme sourire
Authors: Brès Yvon
Published: May 2018

Il s’agit des aspects physiologiques, psychiques, voire « métaphysiques » du fait de rire et non, comme chez beaucoup d’auteurs, à commencer par Bergson, des causes du rire, par exemple le comique. À partir du rire sarcastique, on prend en compte une éventuelle culpabilité liée au rire comme « morsure », donc comme source de remords et de névrose. Mais, au-delà de la catharsis négative de type freudien, tout rire apparaît comme renvoyant aux premières figures d’attachement, en particulier au sourire de la mère, comme le dit la 4 e Bucolique de Virgile.

Elongation Rule of the Longitudinal Fiber of the Continuous Roll Forming Part
Authors: Li Yue , Yang Shu Chen , Wang Mi , Lu Guo Long
Published: May 2018

Continuous roll forming is a novel technique for low-cost, high-efficient manufacturing of three-dimensional surface part. Comparing with conventional continuous forming (using at least three rolls), continuous roll forming employs an upper and a lower flexible rolls to shape the sheet metal. The desired forming shape can be obtained by controlling the profile of the flexible roll and the gap between upper and lower flexible rolls. Modeling and simulation of the continuous roll forming process based on finite element analyses is established to investigate the elongation rule of the longitudinal fiber of the continuous roll forming part. The length of the longitudinal fiber at different positions across the thickness direction is discussed, and the mechanism of the longitudinal deformation is clarified. The following conclusions are obtained. When the flexible roll profile and the roll gap distribution meet certain conditions and make length of the longitudinal fiber linearly distributed, the longitudinal deformation of the sheet metal can be generated.

Copper foils with 91% cold rolled deformation annealed at temperature between 140°C and 170 °C.The microstructures were observed by EBSD. The mechanical properties were measured at room temperature by tensile test machine and the fracture morphologies observed by SEM. After annealed at 150 °C, recrystallization begins to occur, while the elongation increases evidently and tensile strength decreases sharply. When the temperature rises to 170 °C, recrystallization is complete and the grain starts to grow. When the foils are annealed at 140 °C, it exhibits a strong cold rolling textures characterized by Brass {011}<211> and Cu {112}<111>. After annealed at 170 °C, there are olny weak Brass {011}<211> texture.
The Influence of Homogenization on the Elemental Distribution and Properties of Cu-10Ni-1Fe-1Mn Alloy Ingot
Authors: He Yong Dong , Liu Yu , Su Yu Chang
Published: May 2018

A set of Cu-10Ni-1Fe-1Mn alloys were prepared. Electromagnetic casting, DC casting ingot organization, properties and composition distribution of the alloy were studied using Optical Microscope (OM), Scanning Electron Microscopy (SEM), Energy spectrum analysis (EDS), Xray diffraction (XRD), Brinell Hardness Test, and electrochemical tests. The results suggested that homogenization of the Cu-10Ni-1Fe-1Mn alloy changed its properties and distribution of composition. The results also suggest that electromagnetic casting can refine casting organization, homogenize the composition of the alloy, and the casting mechanical performance is superior compared to those of DC casting. However, the composition between Dendritic branch and Dendrites was still not homogeneous. After 1 h of homogenization treatment at 950°C, the ingot composition distribution became more homogeneous, and its stiffness decreased. The tube prepared by squeezing the homogenized ingot, was soaked in 3.5% NaCl solution for 240 h, after which the tube blank surface remained a bright metal luster and XRD analysis indicated that a Cu2O protective film of high density covered the surface of the tube. The homogenization treatment significantly improved the corrosion resistant properties of the alloy tubes.

In this paper, we reported on the preparation of porous materials via a reaction under Autogenic Pressure at Elevated Temperature (RAPET) at 700°Cusing natural product and alkoxides as precursors. The RAPET is a new simple efficient method to prepare inorganic materials. The porous carbon and its composite materials were prepared via the method of RAPET using natural products such as sweet potato, coriander, the absorbent cotton and viscose fiber doped by tetrabutyl titanate (TBOT) and tetraethoxysilane (TEOS). The reaction temperature of RAPET was 700°C. The carbon and its composites were studied with scanning electron microscopy (SEM), X-ray diffraction (XRD) and nitrogen adsorption-desorption measurements. The BET surface area of the materials are different from 4m2/g to 405m2/g. The XRD investigation indicates that the phases of the TiO2 in the carbon/TiO2 composites are anatase. The materials show a certain charge-discharge performance.

TiO2 nanocrystalline powders were prepared by sol-gel method with different process parameters. The phase, morphology and the luminescent property of TiO2 nanocrystalline powders were characterized by XRD, SEM and PL, respectively. The results indicated that the synthesized TiO2 nanocrystalline powders were transformed from anatase into rutile with the increasing of heat treatment temperature, which begin at the temperature of 500 oC and was almost completed at the temperature of 700 oC. And with the increasing of pH value the rutile proportion become larger, the nanograins become fine and powders agglomeration was decreased. The good performance TiO2 nanocrystalline powders were obtained when prepared temperature was 500°Cand pH value was 4. PL results show broad and strong luminescence band appeared near 470nm when TiO2 nanocrystalline powders were excited at 325nm at room temperature.
Reestructuraciones subjetivas en las sociedades laborales: separación y exclusión de socios

Published: May 2018

Se estudia el derecho de separación y la exclusión de socios en las sociedades laborales destacando sus connotaciones propias por motivo de su configuración especial como sociedades capitalistas integradas en el ámbito de la economía social. El artículo 16 de la Ley 44/2015, de 14 de octubre, de Sociedades Laborales y Participadas (en adelante, LSLyP) regula, por primera vez, la separación y la exclusión de socios, constituyendo dicha materia una de las principales novedades de la nueva regulación al no existir, hasta ese momento, una regulación especial en el ámbito relativo al derecho de separación, así como tampoco en el correspondiente a la exclusión de socios en las sociedades laborales. Tanto la separación como la exclusión de socios suponen reajustes en la estructura interna societaria posibilitando la continuidad de la organización societaria laboral, pero sin que dichos procesos sean ajenos a múltiples interrogantes necesitados de una adecuada respuesta jurídica dentro del ámbito, más general, de las reestructuraciones subjetivas en las sociedades laborales, que no han sido suficientemente abordados en su nueva regulación.
Las entidades asociativas prioritarias como instrumento de integración de empresas agroalimentarias. Dificultades y oportunidades de su reconocimiento
Authors: Hernández Cáceres Daniel
Published: May 2018

Ante la atomización existente en el sistema cooperativo español y la consiguiente falta de nivel competitivo de las cooperativas españolas en el mercado internacional, se desarrolló la Ley 13/2013, de 2 de agosto, de fomento de la integración de cooperativas y de otras entidades asociativas de carácter agroalimentario, que pretendía hacer frente a estos problemas. Obteniendo la calificación de “Entidad Asociativa Prioritaria” creada por dicha Ley, dichas entidades tendrán acceso preferencial a subvenciones y ayudas, lo mismo que las entidades que se encuentren integradas en ellas y los productores agrarios. Pero para la obtención de esta calificación se van a encontrar con múltiples dificultades, ya sean intrínsecas de la propia integración como pueden ser los problemas de la concentración/diferenciación, o los requisitos impuestos por la misma Ley y el Real Decreto 550/2014, de 27 de junio, por el que se desarrollan los requisitos y el procedimiento para el reconocimiento de las Entidades Asociativas Prioritarias y para su inscripción y baja en el Registro Nacional de Entidades Asociativas Prioritarias, entre los que se encuentran las exigencias de facturación, comercialización conjunta y el controvertido carácter de supra-autonomía, o con dificultades derivadas de la pluralidad normativa generada por las comunidades autónomas.

Published: May 2018

Corporate Governance (CG) has become a paramount issue due to its greater significance of practicing accuracy, maintaining accountability, establishing effective internal control and regulating organizations for achieving organizational goals. The study is conducted to explore the relationship between corporate governance and firm performance with considering the role of board and audit committee. The multiple liner regression analysis is used as the underlying statistical test on the dependent variables, ROA, ROE and TQ to test the association between the independent variables (board size, board independence, size of audit committee and audit committee composition) with firm performance. Homogeneous purposive sampling has been used. The sample size of the study is 81 listed companies in DSE. The results of the study signify that board independence ratio and audit committee is statistically significant and has positive impact on ROA and TQ. But it is not statistically significant in the case of firm performance indicator ROE in this study. In addition to, Board size is not statistically significant and has negative correlation with firm performance due to group dynamics, communication gaps and indecisiveness of larger groups.

Spinopelvic Fixation
Authors: Esmende Sean M. , Shah Kalpit N. , Daniels Alan H.
Published: May 2018

Fixation at the lumbosacral junction continues to be a challenge for spine surgeons despite advances in spinal instrumentation techniques. The poor bone quality of the sacrum, the complex regional anatomy, and the tremendous biomechanical forces at the lumbosacral junction contribute to the high rates of instrumentation-related complications. Although many spinopelvic fixation techniques have been reported, only a few are still widely used because of the high complication rates associated with previous techniques. Spinopelvic fixation has numerous indications. Long-segment lumbar and thoracolumbar fusions to the sacrum are the most common scenarios in which instrumentation is extended to the pelvis. Surgeons performing complex spinal reconstruction should be familiar with the available techniques, including their potential risks and complications.
Optimization of Phosphogypsum By-Production Using Orthophosphoric Acid as Leaching Solvent with DifferentTemperatures and Leaching Time Periods
Authors: Abdelhadi Monther , Abdelhadi Nafeth , El-Hasan Tayel
Published: May 2018

Phosphoric acid production generates unavoidable calcium sulfate by product (i.e. phosphogypsum (PG)) that is usually disposed either within a nearby located gypsum stacking system. However nowadays this type of industry has been faced with two main problems; these are the formation of huge stockpiles of phosphogypsum that affects the environment due to the presence of harmful radiations that is emitted from the uranium. In addition it contains P2O5>1.0 wt% and fluorine >0.18 wt%, which makes it not suitable for the cement industry. At the same time consuming large quantity of expensive sulphuric acid that becomes a hazardous waste material too. The production ratio of PG verses marketable P2O5 as acid in the world is high as much as 5 tons of PG are produced for each ton of P2O5; in Jordan the ratio is around 5.0 – 5.3 ton of PG / ton of P2O5 produced depending on the phosphate rock composition, which means a huge amount of PG will accumulate at the Fertilizer plant in Aqaba. The major advantages of using orthophosphoric acid as leaching solvent is the decreasing ratio of the residual materials verses marketable P2O5to be589 kg /ton of P2O5 produced. These results were obtained by utilizing the wet agitation leaching technique, compared with 5.0 – 5.3 ton of disposed PG/ton of P2O5produced by Jordan Phosphate Mines Company Ltd., (JPMC). However, this alternative technique resulted in lowerP2O5 extraction, but decrease in bulk of the residue. The disadvantage is the higher dissolution of calcium phosphate and thus considerable calcium well remain in solution.

The primary objective of the details which will be discussed in this article is to set out a general framework necessary to understand the dynamics of the multiple plant ecosystems in relation to the processes of humanisation. This will be within a conceptual orientation of human ecology, biogeography and biological ecology, integrating the time and place, as well as anthropisation and its impacts combined with the data from the studies of the dynamics of the biophysical components of the natural environments. The concepts used to support the arguments are taken from macro-ecology and the human sciences. From an overall perspective, we have highlighted the greatly expanded field of dysfunctions with a view to finding solutions. This allowed us to envisage the possibilities for the reorganisation of the environmental management of Martinique. This future management will make it possible to counteract the factors which are currently contributing to the diminishing resilience of the phytocenoses. This is because the resources associated with the latter should guarantee a sustainable development based on a balance between Nature and Society.
Evaluation of a Multiplex PCR for Detection of the Top Seven Shiga Toxin-Producing Escherichia coli Serogroups in Ready-to-Eat Meats, Fruits, and Vegetables
Authors: Gao Anli , Fishcher-Jenssen Jennifer , Cooper Colin , Li Honghong , Li Jiping , Chen Shu , Martos Perry
Published: May 2018

Background: Ready-to-eat (RTE) meats, fruits, and vegetables contaminated by Shiga toxin producing Escherichia coli (STEC) raise serious concerns because they are often consumed directly without further processing. Objective: To evaluate a multiplex PCR for the detection of STEC across food categories. Methods: Samples (25 g) from seven RTE meat and nine fruit and vegetable matrices were inoculated with each of seven STEC (O157:H7, O26, O121, O145, O45, O103, O111) strains targeting 10 CFU/25 g, enriched in 225 mL of modified tryptone soya broth (mTSB), and tested by a multiplex real-time PCR for stx and eae genes, following U.S. Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS) Microbiology Laboratory Guidebook (MLG) 5B, which was originally validated for meat products and environmental sponge. Results: The mTSB was successful at enriching for STEC in RTE meat, fruit, and vegetable matrices, except for sprouts; however, mEHEC resulted in successful enrichment of target organisms in mung bean sprouts. Suppression of eae results by stx in PCR was observed in six fruit and vegetable matrices. Conversely, suppression of stx gene by eae was not observed. PCR solely targeting eae is recommended if a fruit or vegetable sample tested positive for stx and negative for eae. Despite the significant effect from food matrix, strain, and experimental batch, the cycle threshold of PCR was <30 in inoculated samples, and mostly 30–42 and up in uninoculated samples. Conclusions: The multiplex PCR can be adopted for detection of all seven regulated STEC in RTE meat, fruit and vegetable matrices after validation with cut off value selected and justified based on real samples.
Between Dehumanization and Nosism
Authors: Hashimoto Noriko ,   Philosophy Documentation Center
Published: May 2018

The characteristic feature of modernized systematic environment is realized by one little, thin box named a smart phone or iPhone. By touching the surface, it can open various kinds of technologically magnified internet environment, and bring us into so-called world-wide information society. Our surrounding world is changed to a “technologically developed imaginary world”, virtual reality, where we can live and enjoy. Through this instrument we will be an “anonymous person” for helping people but we may hurt another person’s dignity. It is possible to hide one’s own “self’ behind the technological tool. People always look at the surface of smart phone and concentrate upon outer world without consciousness. It is the crisis of “self’, because of a lack of thinking. Unfortunately, dehumanization will occur. But for solving transnational problems, for example global warming, refugees, etc., we must change our ethical attitude from nosism without any responsibility to an awakening consciousness or living together as “world citizens”.
Ethics and the European Cultural Environment
Authors: McCormick Peter ,   Philosophy Documentation Center
Published: May 2018

Moral naturalism in Europe and elsewhere today is the view that only the natural sciences can satisfactorily analyze the ethical value of persons. Many thoughtful people appear still to believe that the natural sciences can “reduce” the distinctive ethical value of persons ultimately to microphysical terms. Such an apparently widespread belief in part of the EU cultural environment today, however, raises serious questions. - In this EU context and in the Symposium contexts of Tomonobu Imamichi’s (1922-2012) eco-ethical concerns about “a new ethics for our new times,” I would like to offer here two sets of critical observations in support of non-naturalistic accounts of the ethical value of persons. The first group comprises reasons why even some impressive contemporary forms of scientific ethical naturalisms of the person continue to be surprising. And the second, briefer set comprises several elements only of what a non- naturalistic ethics of the person might require.
The Pragmatic Turn in Democratic Theory
Authors: Rasmussen David M. ,   Philosophy Documentation Center
Published: May 2018

The pragmatic turn away from epistemology could mean a number of things for the definition of the future of political theory. First, political liberalism would mark a distinct departure from comprehensive liberalism that is based solely on epistemological justification of fundamental liberal notions. Second, the pragmatic turn would cause Rawls to modify his long-time emphasis on constructivism, moving from Kantian constructivism to political constructivism, and implicitly adopting more substantive approach. Third, the fact of pluralism would radically open up the question of the foundation for consensus, which would lead to an emphasis on constitutionalism. Fourth, this move, innovative as it was, would lead to the establishment of an association between constitutional interpretation and public reason. Finally, this set of moves associated with the pragmatic turn would essentially set up a series of constraints when it comes to evaluating public reason from an international perspective.
Responsabilité et l'éthique de l'environnement

Published: May 2018

This paper demonstrates the importance of the concept of responsibility as the foundation of an ethics of the environment, in particular in the fields of politics and economics in the modem civilization marked by globalization and technological progress. We can indeed observe a moralization of responsibility going beyond a strict legal definition in the development of an ethics of the environment. Accordingly, the concept of responsibility for the environment and for sustainability is the key notion of international development in order to understand the ethical duty of a modem technological civilization.
Garder ouverte la question de la technique pour penser l ’éthique environnementale
Authors: Reber Bernard ,   Philosophy Documentation Center
Published: May 2018

Environmental ethic depends on technological ethics. We must therefore think of the technique with all its virtualities and not merely as an instrument. Heidegger’s approach to technique avoids this reduction. Brought closer to the language it questions its essence. With modem technology that essence does not advance production but provocation, by which nature is ordered to deliver an energy that can be extracted for maximum utilization and lower costs. The way of producing poetry remains open yet. This article reads again this difficult text, indicates some limitations, and tries to take the better of its wealth for contemporary debate crossing environmental and technological ethics.
Social Justice in Sun Yat-Sen ’s The Three Principles of the People
Authors: Dy Manuel B. ,   Philosophy Documentation Center
Published: May 2018

The intent of this paper is to derive an understanding of social justice from Dr. Sun Yat-sen’s San Min Chu I, The Three Principles of the People. Sun Yat- sen, the founder of modem China, gave a series of lectures in 1924, setting the goals of the revolution against the Qin dynasty and the foundation of a modem China. The word “justice” is mentioned only once in the lectures and it is paired with “faithfulness,” or trust referring to the ancient moral character or virtue. And yet underlying the whole programme is a notion of justice that is not interpersonal but social. The first part of the paper gives a summary of the meaning of the three principles: nationalism, democracy and people’s livelihood. The second part attempts to draw the meaning of social justice from the three principles, hopefully showing the relevance of Sun Yat-sen’s ideas to our time.
Confucian Golden Mean as Justice
Authors: Kim Sang-Hwan ,   Philosophy Documentation Center
Published: May 2018

The Confucian concept of Jhongyong corresponds to the Western idea of metaphysical justice, and encompasses similar ideals to the Aristotelian golden mean. Herein is an approach to this Confucian concept from the perspective of comparative philosophy, its aim being triple: to expound on the central or representative position that the concept of Jhongyong takes in Confucian philosophy, to analyze various semantic spectrums of this Confucian concept, and to clarify the complex relationship it has with other Confucian ideas and principles.
From the Moral to the Political
Authors: Rasmussen David ,   Philosophy Documentation Center
Published: May 2018

This article focuses on the problem of political legitimacy: first, by finding it to be the driving force in the Rawlsian paradigm moving from a focus on the moral to one on the political; second, with the help of a consideration of multiple- modernities theory, by arguing for a version of political liberalism freed of its western framework; and third, by applying that framework to current debates over the meaning of democracy in a Confucian context.
Toward a comprehensive taxonomic revision of the “hirculus” group of American Onthophagus Latreille, 1802 (Coleoptera, Scarabaeidae, Scarabaeinae)
Authors: Rossini Michele , Vaz-de-Mello Fernando Z. , Zunino Mario
Published: May 2018

The taxonomy of the American Onthophagus Latreille, 1802 included in the “hirculus” group is revised, and a study of their morphology allows for the delineation of five species-complexes. Herein, we provide a diagnosis of the “hirculus” group, an illustrated key to the complexes, along with a descriptive overview of their taxonomy and geographic distribution. Onthophagus hirculus Mannerheim, 1829 is considered to be a junior synonym of O. hircus Billberg, 1815, which is here demonstrated to be a valid species name. Thus, the “hirculus” group is here renamed the “hircus” group. Furthermore, a general scheme of the genital organs of American Onthophagus is provided, including names of different anatomical parts and a brief discussion on the need for nomenclatural stability for the genitalia of scarab beetles.

Summer book club—a collaborative achievement: Using tech, time, and resources to engage students effectively
Authors: Jansen Annie
Published: May 2018

During summer term, an academic library can be a very quiet place. With fewer students on campus, more online classes, and shorter library hours, there is often a lack of interaction between librarians and students. This is a missed opportunity to engage those students who are on campus.

Choosing And Using Games In The Classroom
Authors: Gresalfi Melissa Sommerfeld
Published: May 2018

Clearly, digital games capture the interest and passion of children and adults alike, and not just for their entertainment value. New games are being developed every day that claim to support learning of academic skills and concepts. It makes sense that games would be good at this—they are good at capturing attention, sustaining engagement, providing interesting contexts, and giving feedback about performance. Still, despite evidence on the effectiveness of games (Clark, Tanner-Smith, and Killingsworth 2016), nearly all published research features games that were developed by researchers and that are not widely available. Games that are available through sites like BrainPop or various app stores are not generally the subject of research demonstrating their effectiveness, including those that have received multiple media awards. Indeed, some available apps even include mathematical inaccuracies or outright errors (Cayton-Hodges, Feng, and Pan 2015).

Eating Disorders and Depression in Adolescents: The Impact of Socioeconomic Factors, Family and Peer Relations
Authors: Livazović Goran , Mudrinić Iva
Published: May 2018

This paper analyses the relation between socioeconomic characteristics, family and peer relations, depression and eating disorders with 218 (144 female, 66.1%) participants aged 14-19 from Croatia. The questionnaire encompassed questions on socioeconomic traits, family and peer relations, depression and anorexia, bulimia, binge eating and orthorexia. Girls reported most dissatisfaction with the abdominal region (38.5%), thighs (31.2%) and breasts (16.1%). Boys reported most dissatisfaction with the abdomen (12.4%), chest (10.1%) and legs/calves (7.3%). Gender was significant for depression (p<.001), anorexia (p<.01), bulimia (p<.001) and binge eating (p<.05), with girls scoring higher on all scales. Age was significant for depression (p<.05) in younger participants, and orthorexia (p<.05) for older adolescents. Participants from vocational schools reported significantly higher family life satisfaction (p<.01), while gymnasium students reported significantly higher depression (p<.000), bulimia (p<.01) and binge eating behaviour (p<.01). Higher mother’s educational level was significant for anorexia (p<.05) and orthorexia (p<.01). Family relations correlated negatively with bulimia and binge eating, but positively with orthorexia. Peer relations were not significant for eating disorders. Eating disorders show positively correlated comorbidity (p<.000), and were significantly correlated to depression (p<.000). Anorexia is best predicted by bulimia (p<.001), orthorexia (p<.001), depression (p<.01) and mother’s education (p<.01). Bulimia is strongly predicted by anorexia (p<.001), binge eating (p<.001), depression (p<.001) and gender (p<.001). Binge eating is strongly predicted by bulimia (p<.001), depression (p<.01) and school type (p<.05). Orthorexia is strongly predicted by anorexia (p<.001), family relations quality (p<.05), the mother’s education (p<.05) and school success (p<.05).
Le cannabis et ses effets délétères : pour un débat plus nuancé
Authors: Jobidon Laurence , Jutras-Aswad Didier
Published: May 2018

Alors que plusieurs États américains ont fait le choix d’assouplir la législation entourant l’usage récréatif du cannabis et qu’au Canada, cette substance est encadrée par un programme fédéral pour son utilisation thérapeutique, le débat sur l’utilisation du cannabis et ses effets néfastes continue de faire couler beaucoup d’encre. S’éloignant souvent des données probantes, ce débat est généralement marqué par des positions clivées qui ne rendent pas compte des nuances récemment apportées par les données scientifiques sur le sujet. Afin de pouvoir bien évaluer les risques que pose cette substance, nous suggérons ici de délaisser le questionnement dichotomique quant au fait que le cannabis cause, ou pas, certains problèmes de santé au profit d’une discussion sur les facteurs modulant la relation entre le cannabis et certains effets délétères potentiels, notamment sur le plan de la cognition, de la psychose et de la toxicomanie. Nous discutons ainsi de certaines données sur la composition du cannabis, son mode d’utilisation, le type de population en faisant usage et la présence de stresseurs environnementaux, qui semblent tous moduler les risques associés à la consommation de cannabis. Devant les données indiquant que le cannabis est une substance psychoactive possédant à la fois des effets délétères et bénéfiques, et au regard du fait qu’une minorité d’individus éprouveront des difficultés après en avoir consommé, il nous semble crucial de faire bon usage et d’approfondir la littérature scientifique portant sur ces facteurs modulateurs. Nous pensons que cela pourrait permettre de mieux informer la population et prendre des décisions plus éclairées, notamment quant aux modalités entourant un éventuel changement au statut légal du cannabis.
