Géothermométrie comparée de roches du faciès granulite du Rogaland (Norvège méridionale)
Authors: Jacques de Dixmude Sophie
Published: October 2018

Les métabasites et les gneiss à grenat-cordiérite de l'encaissant granulitique du complexe éruptif du Rogaland méridional ont fait l'objet d'études géothermométriques. L'application de différents géothermomètres proposés dans la littérature à trois types d'associations (2 pyroxenes, ilménite-magnétite et grenat-cordiérite) est discutée sur base d'équilibre thermodynamique et du chimisme des minéraux des roches étudiées. La plupart des pyroxènes et des oxydes se sont équilibrés entre 800° et 900° C alors que les couples grenat-cordiérite fournissent des températures comprises entre 700° et 750° C. Les différences entre les résultats obtenus par des méthodes différentes sont discutées. La présence éventuelle d'un gradient thermique centré sur le complexe anorthositique est proposée.
Les bytownites du Rift d'Asal. Première partie : étude des verres basaltiques inclus dans les mégacristaux : nouvelle approche pour la connaissance de certains processus pétrogénétiques
Authors: Clocchiatti Roberto , Havette Ledebt Andrée , Weiss Jacqueline , Wilhelm Serge
Published: October 2018

Dans les mégacristaux de bytownite d'Asal (République de Djibouti, ex T. F. A. I), au cours d'une croissance rapide et non homogène, du magma parent, actuellement présent dans les cristaux sous forme d'inclusions vitreuses, a été piégé.

L'étude optique, les réanimations magmatiques suivies puis contrôlées sous le microscope de chauffe et les différentes techniques analytiques (microsonde électronique, microanalyseur ionique) ont permis :

— de déterminer la composition chimique de ces verres magmatiques qui correspond à celle d'un basalte à affinité tholéïtique ;

— de connaître les derniers événements thermiques subis par le cristal pendant la mise en place de la lave ;

— d'estimer la température minimale de cristallisation du minéral hôte à partir du liquide inclus ;

— d'obtenir, en fonction de la température, un plagioclase zoné de plus en plus sodique : An 85 à An 51 de 1 200 à 1 050 + 25° C ;

— d'obtenir dans le liquide, à partir de x 100° C, la cristallisation quasi simultanée d'olivine, de plagioclase, de pyroxène et de minéraux opaques qui se dissolvent aux environs de 1 200° C ;

— de mesurer la vitesse de croissance d'un cristal d'augite suivant l'axe C : 3 à 4 µm/mn à 1 150° C ;

— d'obtenir des cristaux d'augite zonés qui présentent une texture en «sablier » lorsque l'on fait varier la température ;

— de suivre les variations de composition chimique de l'inclusion qui se produisent au cours de la cristallisation de l'auréole feldspathique et des autres phases.

La signification pétrogénétique des inclusions vitreuses et l'intérêt de leur étude dans le domaine des roches éruptives sont discutés.
Quelques aspects du métamorphisme dévonien en Bas-Limousin (Massif central, France)
Authors: Santallier Danielle , Floc'h Jean-Pierre , Guillot Pierre-Louis
Published: October 2018

La série du Bas-Limousin a été affectée par un métamorphisme polyphasé d'âge dévonien. La culmination du métamorphisme est de type barrovien, avec un gradient géothermique voisin de 25° C/km. L'intensité croît du Sud-Ouest vers le Nord-Est depuis la zone à chlorite jusqu'à la zone à silli-manite. Les formations mésozonales montrent d'abondantes reliques de paragenèses précoces essentiellement éclogitiques et ultrabasiques. D'après leur répartition cartographique, ces reliques témoignent de l'existence d'une phase précoce à haute pression. Les dernières manifestations du métamorphisme sont de type basse pression ; elles sont le plus souvent de caractère anatectique et correspondent à un gradient géothermique plus élevé que celui de la phase principale.
Les mécanismes de la métasomatose
Authors: Fonteilles Michel
Published: October 2018

The metasomatic processes are described mainly according to Korzhinskii's method, but these phenomena are considered in relation to a general model of the behaviour of the water phase which plays an essential part in such processes, because diffusions of pétrographie importance occur only in water, and because water is the medium through which components may be brought in or taken away in the case of infiltration metasomatism. This paper includes a discussion of the hypothesis of local chemical equilibrium, a recall of the perfectly mobile component concept, and of the difference between an inert component in Korzhinskii's sense and a perfectly inert component, a discussion of the usefulness of Korzhinskii's Go function, and a presentation of his phase rule. It shows how the distinction between perfectly mobile and inert (especially perfectly inert) components permits an interpretation of whole-rock chemical analyses in the case of metasomatism. A few results obtained by metallurgists on ternary diffusion are introduced, with indications about the way they may be useful in the case of petrology. Concerning infiltration, a discussion is introduced of Korzhinskii's theory of zonality of precipitated minerals, which is based on the doubtful postulate of the supersaturation of the solutions at their source. The volume problem is considered : Lindgren's law of constant volume is ill adapted for thermodynamic discussion. Korzhinskii's postulate of the systematic presence of a precipitated mineral, results from an erroneous application of the phase rule. The phenomena of filling and closing of pores, when metasomatic reactions result in a volume increase, do not necessarily occur, for no component may a priori be considered as perfectly inert.
Le métamorphisme progressif des formations d'origine pélitique du flanc sud du massif de l'Agout (Montagne Noire, France). I. Isogrades et faciès de métamorphisme
Authors: Demange Michel , Gattoni Laurette
Published: October 2018

Studies on the progressive metamorphism on the pelitic rocks on the southern slope of the Agout massif (Montagne Noire, France) show a suite of metamorphic facies, characterized by the following critical paragenesis :

— chlorite, muscovite ;

— chlorite, muscovite, biotite ;

— chlorite, muscovite, biotite, cordierite ;

— chlorite, muscovite, biotite, garnet ;

— chlorite, muscovite, biotite, staurolite ;

— muscovite, biotite, staurolite, cordierite ;

— muscovite, biotite, andalusite ;

— muscovite, biotite, sillimanite.

The physical conditions of the metamorphism :

3.5 kbars — 500-550° C, for the cordierie zone ;

4-4.5 kbars — 650-700° C, for the sillimanite zone ; have been estimated by field and microscopic observations and related experimental data.

The appearance of garnet is further discussed in terms of relative ratios of iron-magnesium-manganese-calcium in whole rocks and basicity of the plagioclase.

Published: October 2018

L'étude expérimentale de la stabilité de la blende dans le système Zn-Cd-S a été réalisée à différentes températures et à fugacité de S2 contrôlée par l'équilibre Sliq ⇄ Svap.

La blende est alors la seule phase stable pour des teneurs en CdS allant jusqu'à 12,2 moles % à 650 °C, 10,3 à 730° C et 7,6 à 800° C. La wurtzite est la seule phase stable à partir de 14,3 mole % de CdS à 650° C, 11,5 à 730° C et 9,2 à 800° C. Pour les teneurs intermédiaires, les deux phases coexistent.
Hermes the Craftsman: The Invention of the Lyre
Authors: Romani Mistretta Marco
Published: October 2018

Hermès, dieu artisan : l’invention de la lyre.

À quels savoirs faut-il recourir pour bâtir un objet textuel ? Comment se peut-il que la construction d’un objet révèle la nature de la maîtrise pratique et théorique de l’artisan ? Mon analyse de l’invention de la lyre dans l’hymne homérique à Hermès (Hymnes homériques, V, 25-61) porte sur ces questions. Dans le texte de l’hymne, la construction de l’instrument explore la notion de téchnè au moyen d’une figuration nette et détaillée des procédés de fabrication de la lyre. La mort, métamorphose, et renaissance de la tortue invitent à réfléchir sur la puissance inventive d’Hermès, qui rend possible l’enchantement et l’ensorcellement provoqués par le son de la lyre. Ma contribution se propose donc de préciser les enjeux conceptuels et interprétatifs du rôle du dieu en tant qu’artisan de la création musicale et poétique. En transformant le cadavre de la tortue en instrument donneur d’immortalité, le dieu du commerce et des échanges exerce en même temps le pouvoir d’harmoniser les contraires et, par conséquent, celui d’unifier théorie et pratique, potentialité et résultat, pensée et action.
De l’Iliade à l’Odyssée : l’émergence d’une pensée de la sensation tactile et de l’unité du corps
Authors: Galhac Sylvie
Published: October 2018

Le but du présent article est d’étudier le toucher chez Homère dans la perspective d’une remise en cause de la thèse de Bruno Snell selon laquelle il n’existe pas d’unité du corps et donc de conception de celui-ci dans les poèmes homériques. L’on examine d’abord le corps en tant qu’il est objet du toucher puis le corps en tant qu’il permet le toucher et un tel examen montre que c’est une spécificité de l’Odyssée non seulement de rendre réellement compte de sensations tactiles mais aussi de témoigner, par le biais des expériences tactiles qu’elle relate, d’une pensée de l’unité du corps d’autant plus remarquable que cette unité est envisagée sous différents aspects (externe, interne ou consistant en un lien entre parties externes et parties internes du corps).
Controverses vétérinaires autour du toucher
Authors: Gitton-Ripoll Valérie
Published: October 2018

Dans la médecine vétérinaire antique, le sens du toucher participe au diagnostic, par exemple pour évaluer la fièvre, mais est aussi un outil de soin : il faut toucher l’animal, de façon externe (pansage, pansements, traitements), ou interne (palpation rectale, chirurgie), pour accomplir le traitement. Le geste, potentiellement dangereux, est codifié pour ne pas blesser l’animal ; et il était parfois déconseillé en raison des risques de blessures qu’il pouvait entraîner, ou parce que sa pertinence n’était pas démontrée, comme dans la prise du pouls : certains vétérinaires refusaient de mettre sa perturbation en relation avec la fièvre. Ces controverses entre auteurs vétérinaires peuvent être rapprochées des controverses qui avaient opposé les auteurs de médecine eux-mêmes sur les mêmes sujets.
Le Palais des Académies - une résidence urbaine offerte au Prince d’Orange par les Belges
Authors: Strauven Francis
Published: October 2018

The Palais des Académies – an Urban Residence Gift of the Belgians, to the Prince of Orange.

The Palais des Académies, which stands next to the Royal Palace, was originally not devoted to house the Royal Academies of Belgium. It was erected between 1823 and 1828 as the urban residence of the Prince of Orange, United Kingdom of the Netherlands’s Crown Prince. It is usually assumed that the king would have built this building to expose his son as a sort of regent in Brussels, to symbolize the royal authority when he himself resided in The Hague. This is not the case, on the contrary. The palace was given to the prince by the States General / États Généraux against the will of his father, king William I. Officially the parliament made this gesture as a recognition for the heroic conduct of the prince at the battle of Waterloo. But in reality the representatives expressed by this exceptional act, the warm sympathy of the Belgian people for the crown prince, while aiming to establish him as a viceroy in Brussels, awaiting his accession to the throne. The design of the palace was entrusted to Charles Vander Straeten, a Brussels architect trained in the classicist spirit of J. N. L. Durand. He succeeded in incorporating the complex program into a rational and clear plan, expressed in a simple classicist architecture, typical of the late empire style. The interior of the palace was fundamentally transformed in 1860. It was restored in 1969-1976.
« Beaux quartiers » et mixité sociale à Bruxelles au siècle des Lumières
Authors: Bruneel Claude
Published: October 2018

Les guides, descriptions et plans de Bruxelles, tout comme le Calendrier de la Cour,

permettent au voyageur de repérer les «beaux quartiers » de la capitale. Ils sont au nombre de quatre à cinq sur quarante, mais c’est la section du Sablon qui compte le plus d’hôtels de maître. Les dénombrements de population de 1755 et de 1783 permettent d’établir la composition socio-professionnelle de ses différentes rues. Tous les groupes sociaux s’y retrouvent, même si, selon les artères, certains de ceux-ci imposent leur présence massive. Le grand nombre de gens de service n’est pas étranger à la forte présence de la haute noblesse et des grands commis de l’État. Le secteur du commerce et de l’artisanat n’offre pas un profil radicalement différent de celui que reflète le reste de la ville. Toutefois, la spécificité du quartier explique la surreprésentation de certaines activités liées, par exemple, au goût du luxe, à l’habillement ou aux soins capillaires. Du point de vue de la répartition de l’habitat, la mixité sociale se retrouve sous différentes formes : la juxtaposition de groupes sociaux dans différents tronçons d’une même rue ou, au contraire, le mélange des ménages tout au long de celle-ci. Par ailleurs, les artères principales délimitent un périmètre au sein duquel, au gré du développement urbain et de l’augmentation de la population, se sont ouvertes des ruelles et des impasses où domine la population la moins favorisée. Le long de l’axe principal, de la rue aux Laines à la rue de Rollebeek, la ville des élites nobiliaires et administratives s’efface progressivement, amorçant ainsi la transition vers la ville des artisans et des commerçants.
The Origin of Double-peaked Narrow Lines in Active Galactic Nuclei. IV. Association with Galaxy Mergers
Authors: Comerford Julia M. , Nevin Rebecca , Stemo Aaron , Müller-Sánchez Francisco , Barrows R. Scott , Cooper Michael C. , Newman Jeffrey A.
Published: October 2018

Double-peaked narrow emission lines in active galactic nucleus (AGN) spectra can be produced by AGN outflows, rotation, or dual AGNs, which are AGN pairs in ongoing galaxy mergers. Consequently, double-peaked narrow AGN emission lines are useful tracers of the coevolution of galaxies and their supermassive black holes, as driven by AGN feedback and AGN fueling. We investigate this concept further with follow-up optical longslit observations of a sample of 95 Sloan Digital Sky Survey (SDSS) galaxies that have double-peaked narrow AGN emission lines. Based on a kinematic analysis of the longslit spectra, we confirm previous work that finds that the majority of double-peaked narrow AGN emission lines are associated with outflows. We also find that eight of the galaxies have companion galaxies with line-of-sight velocity separations <500 km s−1 and physical separations <30 kpc. Since we find evidence of AGNs in both galaxies, all eight of these systems are compelling dual AGN candidates. Galaxies with double-peaked narrow AGN emission lines occur in such galaxy mergers at least twice as often as typical active galaxies. Finally, we conclude that at least 3% of SDSS galaxies with double-peaked narrow AGN emission lines are found in galaxy mergers where both galaxies are resolved in SDSS imaging.
System-size Convergence of Nonthermal Particle Acceleration in Relativistic Plasma Turbulence
Authors: Zhdankin Vladimir , Uzdensky Dmitri A. , Werner Gregory R. , Begelman Mitchell C.
Published: October 2018

We apply collisionless particle-in-cell simulations of relativistic pair plasmas to explore whether driven turbulence is a viable high-energy astrophysical particle accelerator. We characterize nonthermal particle distributions for varying system sizes up to L/2πρ

e0 = 163, where L/2π is the driving scale and ρ

e0 is the initial characteristic Larmor radius. We show that turbulent particle acceleration produces power-law energy distributions that, when compared at a fixed number of large-scale dynamical times, slowly steepen with increasing system size. We demonstrate, however, that convergence is obtained by comparing the distributions at different times that increase with system size (approximately logarithmically). We suggest that the system-size dependence arises from the time required for particles to reach the highest accessible energies via Fermi acceleration. The converged power-law index of the energy distribution, α ≈ 3.0 for magnetization σ = 3/8, makes turbulence a possible explanation for nonthermal spectra observed in systems such as the Crab Nebula.
First record of Epipompilus excelsus (Bradley, 1944) (Hymenoptera, Pompilidae) as a koinobiont ectoparasitoid of Ariadna mollis (Holmberg, 1876) (Araneae, Segestriidae)
Authors: Villanueva-Bonilla German Antonio , Brescovit Antonio Domingos , dos Santos Eduardo , Vasconcellos-Neto João
Published: October 2018

EpipompilusKohl comprises 52 species of wasps that are parasitoids of spiders; 16 species occur in the Neotropical region and 36 species occur in the Australian region. The biological knowledge of this genus is limited and its interactions and host spiders are still incipient. Here, we report some behavioural and biological characteristics ofE.excelsus, a parasitoid of the tube-dwelling spiderAriadnamollis. We observed anE.excelsusfemale attacking an adult female ofA.mollisin São Paulo, Brazil. We photographed daily the larval development of the wasp, from the egg stage to adult emergence. The entire developmental cycle of the wasp took 24 days. This period was shorter than the developmental periods of wasps belonging to other genera of Pompilidae. Although all species within Pompilidae use spiders as host, they present great behavioural diversity, characterized by different ethological sequences. In conclusion, this study demonstrated that the Neotropical species ofEpipompilusexhibit biological characteristics similar to the Australian species, acting as a koinobiont ectoparasitoid, but displays differences in larval morphology. Studies on other species could elucidate the extent of these differences and similarities, contributing to our understanding of the evolutionary history ofEpipompilus, and consequently of Pompilidae.
Investigation of Non-Academic Data Management Practices to Inform Academic Research Data Management
Authors: Van Tuyl Steven , Whitmire Amanda
Published: October 2018

In recent years, the academic research data management (RDM) community has worked closely with funding agencies, university administrators, and researchers to develop best practices for RDM. The RDM community, however, has spent relatively little time exploring best practices used in non-academic environments (industry, government, etc.) for management, preservation, and sharing of data. In this poster, we present the results of a project wherein we approached a number of non-academic corporations and institutions to discuss how data is managed in those organizations and discern what the academic RDM community could learn from non-academic RDM practices. We conducted interviews with 10-20 companies including tech companies, government agencies, and consumer retail corporations. We present the results in the form of user stories, common themes from interviews, and summaries of areas where the RDM community might benefit from further understanding of non-academic data management practices.

Le séminaire de Ludwig von Mises à l'Université de New York (1948-1969)
Authors: Caré Sébastien
Published: October 2018

Resume Cet article prend pour objet le séminaire hebdomadaire dispensé par l’économiste autrichien Ludwig von Mises à l’Université de New York entre 1948 et 1969. En s’intéressant à la fois au contenu des idées exposées lors du séminaire, et à la forme des relations qui s’y sont constituées (aussi bien entre le maître et ses élèves qu’entre les élèves entre eux), cette contribution se propose d’examiner le double rôle de cette expérience d’enseignement dans la constitution d’une école austro-américaine d’économie et dans la formation du mouvement libertarien.
Le séminaire de Sociologie des œuvres de Pierre Bourdieu
Authors: Fabiani Jean-Louis
Published: October 2018

Resumé Au cours des années 1970, Pierre Bourdieu a donné un séminaire bimensuel à l’École normale supérieure, Rue d’Ulm. Bien qu’elles n’aient pas la réputation des séminaires de Louis Althusser et de Jacques Lacan, qui s’étaient tenus quelques années auparavant dans le même lieu, ces rencontres permettent de mieux comprendre le leadership de Bourdieu dans des années décisives pour sa carrière. L’article vise à donner un éclairage original sur les fonctions intégratrices du séminaire aussi bien que sur la construction d’un réseau international à partir d’invitations. Cette recherche est fondée sur une analyse préliminaire du séminaire à la française, emprunté à l’Université allemande après la défaite de 1870. On montre la relative hétérogénéité du groupe de Bourdieu, qui voit coexister de jeunes étudiants parisiens issus des formations les plus prestigieuses et d’anciens enseignants du primaire d’origine provincial et modeste. Le style charismatique de Bourdieu est analysé comme étant le fondement nécessaire de la structuration du groupe et de sa dynamisation.
Le séminaire comme dispositif collectif académique transitoire
Authors: Monneau Emmanuel
Published: October 2018

Resumé Cet article prend le séminaire comme objet dans une perspective de sociohistoire des disciplines. Il s’appuie sur un séminaire important de la science économique française dans un contexte d’autonomisation de la discipline vis-à-vis du droit dans les universités. Il montre que le séminaire est alors un outil académique pour faire carrière. Cependant, l’importance de ce séminaire ne se limite pas à cette dimension. Il s’appuie sur un programme de recherche qui servira de base à l’économie critique des décennies suivantes. Son organisation ainsi que les participants et leurs trajectoires contribuent au succès de cette entreprise collective qui fait figure de transition d’une organisation de la recherche vers le laboratoire.
Vers une théorie communicationnelle de la société
Authors: Leclerc Arnauld
Published: October 2018

Resumé Cet article étudie le rôle du séminaire de recherche au sein de la théorie communicationnelle de la société défendue par Habermas et Ferry. Il démontre que ce rôle est largement conditionné par le contexte historique dans lequel le philosophe agit et réfléchit en explorant les séminaires de Habermas aux débuts des années 1970 et ceux de Ferry aux débuts des années 2010. Malgré tout, le séminaire apparaît comme un lieu d’élaboration et de stabilisation de la pensée permettant à l’historien des idées d’éclairer partiellement le processus de fabrication de la philosophie. En même temps, le séminaire constitue un lieu de socialisation à une école de pensée et de diffusion de celle-ci reflétant la mutation des impératifs pesant sur la recherche académique.
Abdominal CT Scan Findings of Decompression Sickness: A Case Report
Authors: Schwartz Taylor , Gough-Fibkins Shawn , Santini Roberta , Kopylov David
Published: October 2018

This case report depicts the radiologic findings of a 51-year-old male presenting with Decompression Sickness. Decompression Sickness is diagnosed clinically, therefore radiologic imaging of this disease entity is limited. Our patient's history includes a scuba dive to depth of 110 feet with a descending time of 24 minutes and an ascending time of 8 minutes. The patient subsequently presented to the Emergency Room with symptoms of shortness of breath and abdominal pain. The abdominal pain prompted physicians to explore further, and hence computed tomography (CT) imaging of the abdomen and pelvis was performed. This case report demonstrates a striking and unique gas pattern in both the systemic and portal venous system of our patient and provides an excellent example of the imaging findings of Decompression Sickness in the literature.
Annular Pancreas in an Adult Presenting with Acute Pancreatitis
Authors: Huddleston V Sam , Lippuner Veronica , Dyer Andrew W.
Published: October 2018

Annular pancreas is a rare congenital condition in which tissue from the head of the pancreas partially or completely surrounds the second part of the duodenum.  This condition has a variable clinical presentation in adults and children.  Radiologists should be aware of the imaging findings in adults as an annular pancreas can be overlooked or misdiagnosed in this patient population.  In this case report we describe an adult patient with pancreatitis associated with the computed tomography findings of a complete annular pancreas and discuss additional imaging techniques and findings for differential diagnoses of this condition.
Finding the “Funny Bone” in the Class Skeleton
Authors: Seiverd Kyle
Published: October 2018

Some teachers have the natural ability to captivate their students, while others struggle to maintain classroom control. Utilizing comedy as a tool to deliver and maintain an audience's attention is something that comics and GATEs have in common. Some teachers use videos, memes, or one-liners to their class laugh. For the author, a career in comedy began with family joke telling. It was when a high school student enrolled in standup comedy class that he unlocked his comedic talents and better prepared himself to become a teacher. The highs and lows of joke writing, stress of a performance, and its connection to teaching are described in detail.

Published: October 2018

Technological advancements and imaging evolution in contemporary medicine continue to change the ways medical education and clinical care are delivered. Historical methods of learning anatomy through human cadaveric dissection may be supplanted by three-dimensional renderings, injection models, and virtual reality simulations. The cost effectiveness of new imaging and study modalities may demonstrate major advantages in the logistics of information delivery, cost containment, and skills development in the current healthcare environment.
Technological and Ethical Challenges of Online Education
Authors: Haar Lauren , Kaja Simon
Published: October 2018

The impact of technology can be felt throughout the medical education continuum. From online learning environments in blended learning approaches to exclusively providing the preclinical curriculum online, there is a growing need to optimize the way that technology supports self-directed learning in the next generation of medical professionals. In this chapter, the authors address issues of best practice surrounding the development of virtual content for medical education. The information presented will be integral for medical education professionals, basic science/clinical faculty, and educational assessment specialists with an interest in the use of technology for contemporary medical education. The goal is to offer an overview of the theory and ethics behind adopting an online strategy for medical education. An emphasis is placed on developing best practices for presenting content, a comparison of blended and online-only approaches, and the ethical considerations necessary for the successful training of medical professionals online.
Sense of Belonging and Student Success at Historically Black Colleges and Universities

Drawing connections between a recent survey of KIPP alumni and literature about HBCUs, this chapter reviews extant literature on the history and significance of Black colleges, the faculty and staff employed by HBCUs, and students educated at HBCUs. Then, the chapter posits sense of belonging as a critical factors in their academic success, using Strayhorn's theory of college students belonging. Strong implications for policy, practice, and programs are included.
Advancing Retention and Engagement Strategies Through Effective Online Mediums
Authors: Eakins Amanda , Eakins Sheldon L.
Published: October 2018

Historically Black Colleges and Universities in the USA continue to play a pivotal role in educating students within the African diaspora as they provide a practical and resourceful platform for students to develop a sense of belonging through community and organizational outreach activities on campus. However, the student population in higher education as we used to know has changed, and adult learners now make up a large majority of the enrolled population. This chapter aims to review the history of online education and will provide a conceptual framework for incorporating online learning in an institution's student success plan for both their traditional and non-traditional students. The author will also review the needs of the adult learners and provide an overview of how the development and integration of online learning programs and collaborative efforts with other institutions through dual enrollment and degree MOU programs can foster growth at Historically Black Colleges and Universities.
Cognitive Apprenticeship for Dissertation Writing
Authors: Swanson Karen Weller , West Jane , Carr Sherah , Augustine Sharon
Published: October 2018

The purpose of this chapter is to make explicit how faculty members at one institution adopted the cognitive apprenticeship model as a way to support doctoral students' development from student to scholar. The efforts in doing so focus heavily on dissertation thinking and writing because the dissertation is such a significant, culminating element in any doctoral student's experience. Writing a dissertation is something one only does once, and the process is typically designed to be an individual test of the ability to make connections between theory and practice, conduct research, and communicate about research in a scholarly manner. The isolation of dissertation writing often results in doctoral students' remaining ABD (all but dissertation). Most professors who have mentored a doctoral student through the dissertation process can attest that success in completing coursework does not necessarily lead to success in completing a dissertation. Because dissertation writing is markedly different from other kinds of academic and professional writing, many doctoral students need explicit support such as cognitive apprenticeship to guide their journey through the dissertation writing process.
The Roles of Quantitative and Qualitative Data Gathering in Survey Research
Authors: Boeren Ellen
Published: October 2018

This chapter critically explores the tendency of research methods books to discuss survey research under the header of quantitative research approaches. It starts by providing a brief history on survey research, sets out core definitions, and situates survey research in the current methodological literature. It explains the difference between cross-sectional and longitudinal data and provides insight on the steps to undertake when designing a research project. The chapter then explores the nature of specific survey questions and the differences in format based on whether one is gathering qualitative versus quantitative data.

Community-Engaged Research
Authors: Zimmerman Aaron Samuel
Published: October 2018

Community-engaged research describes an approach towards research and a stance towards scholarship that arose in response to the criticism that institutions of higher education functioned only as ivory towers, disconnected from real-world problems. This chapter is intended to serve as an introduction to the concept of community-engaged research. Topics covered will include the definition of community-engaged research, the criteria for the evaluation of community-engaged research, inherent challenges associated with community-engaged research, and strategies that institutions of higher education can employ as a means of cultivating and sustaining community-engaged research among faculty.

Published: October 2018

Although research and writing for publication are seen as important responsibilities for most graduate students and faculty, many struggle to understand the process and how to succeed. Unfortunately, writing centers at most universities do not cater to the research and publishing needs of graduate students and faculty, but instead to course-specific needs of undergraduate students. This chapter aims to describe initiatives undertaken to address the scholarly writing and publication needs of graduate students and strategies and programs for the improvement of scholarly writing and provide insight into the kind of learning that can take place in a university writing center. This chapter may be especially helpful to educators who seek to create services at their own institutions for graduate students.
The Effects of Political and Economic Risk on FDI
Authors: Ayhan Fatih
Published: October 2018

Foreign direct investments (FDI) are becoming the key element in achieving development in developing countries. On the global scale, FDIs reached the level of $1,75 trillion back in 2016. FDI also brings lots of economic benefits to host countries. However, beyond these economic indicators, political structure and social characteristics of a host country also have special importance for investors' decisions. Political risk indicators cover mainly democratization level, political/government instability, war, immigration problems, problems with neighboring countries, internal and external conflicts, corruption level, military and religious influence on politics, law and order, ethnics tensions, property rights protection, national security and geographic situation - all of these factors also deeply affect decisions on FDI. Also, some basic social characteristics for host countries can play the catalyzer role for FDI, such as literacy rate, education opportunities, etc. The aim of this study is to examine theoretically the relationship between political and economic risks on the one hand with FDI on the other. It is aimed to show the theoretical background for the political and economic risk factors. Statistical figures on the FDI trends worldwide will be also presented.
Taxation System in Slovakia
Authors: Rabatinová Marcela , Válek Juraj , Kušnírová Jana
Published: October 2018

A common European area without any internal borders between the EU Member States creates greater risks in terms of tax evasion and avoidance by economic entities. Increasing tax burden during the financial and economic crisis led to an increase in tax evasion as a result of changes in the behavior of taxpayers. This chapter deals with the current problems of taxation in Slovakia in the context of effective tax collection and tax evasion prevention. The aim of the chapter is to assess the development of corporate income tax, excise tax on alcoholic beverages, and value added tax, which are considered to be the most risky ones in terms of tax evasion.

Authors: Ai Tran Huu , Ushakov Denis
Published: October 2018

In this chapter, the authors, operating the criteria of rigid and comfortable national taxation regimes, attempt to evaluate the stimulating impact of country's taxation systems on the dynamics of their macroeconomic growth and country's participation in the world trade. Therefore, the chapter presents the authors' conclusions concerning the efficiency of fiscal instruments for economic growth stimulation and external trade attractiveness increase as applied to the majority of contemporary states. Based on correlation of indices of tax reformations and trends of the modern countries macroeconomic development, the co-authors present their conclusions on the priority importance of the so-called “taxation comfort” in the context of country's positioning in the global rankings. Research proved a taxation effect in countries' macro-economic growth and external attractiveness stimulating, as well as this effect dependence on the level of countries material wellbeing and infrastructural conditions.
Model of Socioeconomic Development Based on Market Economy and Public-Private Partnership (PPP) Mechanism
Authors: Zeldner Alexey , Osipov Vladimir , Skryl Tatiana
Published: October 2018

This chapter systematizes the main components of the socio-market model of the economy. Its basis is formed by market economy and public-private partnership as the mechanism stimulating the attraction of private investments. Using the opportunities of the market economy and PPP mechanism creates a real opportunity for the formation of a new model of socio-market economy. This model does not imply the weakening the role of the state and infringement of democracy as such, but rather strengthening of institutions and PPP mechanisms with the aim to attract private investments and improve social relations at the same time. This chapter is thus aimed at revealing the main elements of this socioeconomic model along with the theoretical, methodological, and practical aspects of its main components: the market economy and the PPP mechanisms.
Order Statistics and Clinical-Practice Studies
Authors: Chen E Jack
Published: October 2018

Statistics are essential tools in scientific studies and facilitate various hypothesis tests, such as test administration, response scoring, data analysis, and test interpretation. Order statistics refer to the collection of sample observations sorted in ascending order and are among the most fundamental tools in non-parametric statistics and inference. Statistical inference established based on order statistics assumes nothing stronger than continuity of the cumulative distribution function of the population and is simple and broadly applicable. The authors discuss how order statistics are applied in statistical analysis, e.g., tests of independence, tests of goodness of fit, hypothesis tests of equivalence of means, ranking and selection, and quantile estimation. These order-statistics techniques are key components of many clinical studies.

Authors: Mouri Kousuke , Ren Zhuo , Uosaki Noriko , Yin Chengjiu
Published: October 2018

The analysis of learning behaviors from the log data of digital textbooks is beneficial for improving education systems. The focus of discussion in any analysis of learning behaviors is often on discovering the relationships between learning behavior and learning performance. However, little attention has been paid to investigating and analyzing learning patterns or rules among learning style of index (LSI), cognitive style of index (CSI), and the logs of digital textbooks. In this study, the authors proposed a method to analyze learning patterns or rules of reading digital textbooks. The analysis method used association analysis with the Apriori algorithm. The analysis was conducted using logs of digital textbooks and questionnaires to investigate students' learning and cognitive styles. From the detected meaningful association rules, this study found three student types: poorly motivated, efficient, and diligent. The authors believe that consideration of these student types can contribute to the improvement of learning and teaching

Authors: Gezgin Deniz Mertkan
Published: October 2018

This article investigates the effect of mobile learning support on students' academic success on a database management systems (DBMS) course. The research was carried out with 36 students attending a state university in Turkey. In this study, a mixed method was used, which includes both quantitative and qualitative data collection techniques. For the quantitative data, the study was conducted in accordance with the pre-test and post-test-based two group quasi-experimental model. For the qualitative data, the descriptive analysis technique was used. The independent sample t-test and paired simple t-test were employed in the analysis phase. According to the findings, mobile learning positively affected students' academic achievement on the DBMS course, in that the students supported by mobile learning were more successful than students supported only by face-to-face training method. Finally, it is seen that the students have emphasized themes of motivation, 1-1 access, and an interest in terms of the effect of m-learning approach on academic success.
Implementation and Evaluation of Flipped Algorithmic Class
Authors: Amira Teimzit , Lamia Mahnane , Hafidi Mohamed
Published: October 2018

Recent years have brought the need for new pedagogical approaches that appeal to the involvement and participation of learners in the learning process. One of these approaches is the flipped classroom, which gives to learners the possibility to prepare for the next class, through pre-recorded video lectures and close-ended problems. Many studies merely replace in-class instructions by videos and use class time for group discussions. Nevertheless, what instructional design framework should we use in planning the overall flipped classroom approach? This article answers this question through exploratory studies conducted at Algeria University. In this work, the authors have used a flipped classroom concept for an algorithmic course like java programming, based on learner's learning style and learner's skill level.

Published: October 2018

The key aim of this study is to provide an overview of students' and instructors' attitudes and perceptions towards the potential benefits and challenges of summative e-assessment for their writing courses at a UAE university. A mixed method of quantitative and qualitative analysis is used. The findings of the study revealed that a majority of student participants reported reasonable satisfaction with the e-assessment tool in terms of screen layout and background, interface design and ease of use and access. However, they indicated their preference to “pen and paper” exams. Instructor participants identified a number of challenges associated with using summative e-assessment in the writing courses, which would require educational institutions to make changes to promote the success of e-assessment.
Discovering Learners' Characteristics Through Cluster Analysis for Recommendation of Courses in E-Learning Environment
Authors: Rawat Bhupesh , Dwivedi Sanjay K.
Published: October 2018

With the emergence of the web, traditional learning has changed significantly. Hence, a huge number of ‘e-learning systems' with the advantages of time and space have been created. Currently, many e-learning systems are being used by a large number of academic institutions worldwide which allow different users of the system to perform various tasks based on their goals. However, most of these systems follow a ‘one size fits all' approach where same resources are offered to learners irrespective of their unique learning requirements. Therefore, personalization is required as a part of e-learning systems which offers resources to learners based on their profile. This research aims to perform cluster analyses in order to validate clusters created through a k-means algorithm. The clusters will be used to classify a new learner into its appropriate class and recommend relevant courses. Finally, the accuracy of the recommendation is evaluated using various evaluation metrics. The proposed recommendation system helps learners to improve their academic performance and hence overall learning process as well.
