Published: December 2017

Abstract
We study the presence of tidal features associated with ultra diffuse galaxies (UDGs) in galaxy clusters. Specifically, we stack deep Subaru images of UDGs in the Coma cluster to determine whether they show position angle twists at large radii. Selecting galaxies with central surface brightness

magarcsec−2 and projected half-light radius

, we identify 287 UDGs in the Yagi et al. catalog of low surface brightness Coma objects. The UDGs have apparent spheroidal shapes with median Sérsic index

and median axis ratio

. The images are processed by masking all background objects and rotating to align the major axis before stacking them in bins of properties such as axis ratio, angle of major axis with respect to the cluster center, and separation from cluster center. Our image stacks reach further than 7 kpc (≳4r
e). Analysis of the isophotes of the stacks reveals that the ellipticity remains constant up to the last measured point, which means that the individual galaxies have a non-varying position angle and axis ratio and show no evidence for tidal disruption out to

. We demonstrate this explicitly by comparing our stacks with stacks of model UDGs with and without tidal features in their outskirts. We infer that the average tidal radius of the Coma UDGs is >7 kpc and estimate that the average dark matter fraction within the tidal radius of the UDGs inhabiting the innermost 0.5 Mpc of Coma is >99%.

Abstract
The ability to perform detailed chemical analysis of Sun-like F-, G-, and K-type stars is a powerful tool with many applications, including studying the chemical evolution of the Galaxy and constraining planet formation theories. Unfortunately, complications in modeling cooler stellar atmospheres hinders similar analyses of M dwarf stars. Empirically calibrated methods to measure M dwarf metallicity from moderate-resolution spectra are currently limited to measuring overall metallicity and rely on astrophysical abundance correlations in stellar populations. We present a new, empirical calibration of synthetic M dwarf spectra that can be used to infer effective temperature, Fe abundance, and Ti abundance. We obtained high-resolution (R ∼ 25,000), Y-band (∼1 μm) spectra of 29 M dwarfs with NIRSPEC on Keck II. Using the PHOENIX stellar atmosphere modeling code (version 15.5), we generated a grid of synthetic spectra covering a range of temperatures, metallicities, and alpha-enhancements. From our observed and synthetic spectra, we measured the equivalent widths of multiple Fe i and Ti i lines and a temperature-sensitive index based on the FeH band head. We used abundances measured from widely separated solar-type companions to empirically calibrate transformations to the observed indices and equivalent widths that force agreement with the models. Our calibration achieves precisions in T
eff, [Fe/H], and [Ti/Fe] of 60 K, 0.1 dex, and 0.05 dex, respectively, and is calibrated for 3200 K < T
eff < 4100 K, −0.7 < [Fe/H] < +0.3, and −0.05 < [Ti/Fe] < +0.3. This work is a step toward detailed chemical analysis of M dwarfs at a precision similar to what has been achieved for FGK stars.

Abstract
We present a study of the connection among black hole accretion, star formation, and galaxy morphology at

. We focus on active galactic nuclei (AGNs) selected by their mid-IR power-law emission. By fitting optical to far-IR photometry with state-of-the-art spectral energy distribution (SED) techniques, we derive stellar masses, star formation rates, dust properties, and AGN contributions in galaxies over the whole COSMOS field. We find that obscured AGNs lie within or slightly above the star-forming sequence. We confirm our previous finding about compact host galaxies of obscured AGNs at

, and find that galaxies with 20%–50% AGN contributions tend to have smaller sizes, by ∼25%–50%, compared to galaxies without AGNs. Furthermore, we find that a high merger fraction of up to 0.5 is appropriate for the most luminous (

) AGN hosts and non-AGN galaxies, but not for the whole obscured AGN sample. Moreover, the merger fraction depends on the total and star-forming IR luminosity, rather than on the decomposed AGN infrared luminosity. Our results suggest that major mergers are not the main driver of AGN activity, and therefore obscured AGNs might be triggered by internal mechanisms, such as secular processes, disk instabilities, and compaction in a particular evolutionary stage. We make the SED modeling results publicly available.
Biens publics mondiaux et institutions internationales : quel avenir pour la Banque mondiale ?
Authors: Kanbur Ravi 
Published: December 2017

La Banque mondiale s’essouffle. Ou bien est-ce pire encore ? Les biens publics mondiaux (BPM) sont souvent présentés comme un moyen de revitaliser, voire de sauver cette institution dont la base financière nécessaire à ses opérations conventionnelles de prêts souverains se réduit considérablement par rapport aux besoins, dans un contexte de concurrence exercée par d’autres acteurs. La Banque mondiale offre toutefois des avantages sur lesquels la communauté mondiale pourrait compter dans le cadre des questions liées aux BPM. Elle s’est forgé une réputation d’excellence technique et bénéficie d’un pouvoir de mobilisation à même de favoriser le consensus sur un éventail de problématiques relatives aux BPM, même si cet objectif ne peut être pleinement atteint sans réformes profondes de sa structure de gouvernance. Elle a acquis une expérience dans le domaine de la gestion des ressources concessionnelles et des subventions, compétence essentielle au financement des actions liées aux BPM. Enfin, elle possède une connaissance des opérations à l’échelle des pays dans la mise en œuvre des modalités spécifiques par pays des instruments relatifs aux BPM. Ce sont là les atouts de la Banque mondiale aujourd’hui, trois quarts de siècle après sa création. Codes JEL : O1, H41, F02.
Des politiques migratoires pour promouvoir le développement
Authors: Yang Dean 
Published: December 2017

Les politiques de développement liées à la migration internationale en provenance des pays en développement suscitent un vif intérêt. La dernière décennie a été marquée par une vague d’études empiriques rigoureuses (dont la plupart s’appuient sur des essais randomisés contrôlés) quantifiant l’impact de telles politiques. Cet article s’intéresse à la littérature sur l’impact des politiques dans cinq domaines : 1) la facilitation de la migration ; 2) l’éducation des migrants ; 3) la réduction des frais de transaction associés aux envois de fonds des migrants ; 4) l’amélioration de la capacité du migrant à contrôler l’usage qui est fait de ses envois de fonds ; et 5) l’amélioration des conditions de travail des migrants. Si des études mettent en évidence l’impact positif de certaines interventions dans chacun de ces domaines, il n’en demeure pas moins que de nombreuses questions restent ouvertes. De futures recherches dans ces domaines et dans d’autres promettent des résultats pertinents en matière de politique.

Mesurer la qualité pour transformer l’hôpital ?
Authors: Bertillot Hugo 
Published: December 2017

Depuis le début des années 2000, les pouvoirs publics français déploient des instruments d’évaluation de la qualité dans les établissements de santé. En procédant à la déconstruction sociotechnique des « indicateurs de qualité », cet article analyse une discrète entreprise de quantification. Mesurant des dimensions peu conflictuelles de la qualité, nourris de savoirs pluriels, équivoques dans leurs usages, les indicateurs de qualité sont suffisamment doux pour ne pas brusquer les professionnels, tout en étant suffisamment robustes pour instiller discipline et auditabilité. Au nom de la qualité, cette technologie de gouvernement est ainsi équipée pour rationaliser l’hôpital en douceur.
« Que personne, parce qu’il est jeune, ne tarde à philosopher, ni, parce qu’il est vieux, ne se lasse de philosopher »

Comme toutes les sciences qui s’intéressent aux communautés humaines, la gestion (ou le management) n’est pas exempte de s’interroger sur son propre construit social et ses valeurs. Tout comme « l’homo economicus », cher aux néo-libéraux est un mythe, hélas toujours révéré par quelques idiots utiles parfois encore proches du pouvoir, il existe bien une mythologie ou des postulats en management comme James G. March l’a fort bien démontré dans son excellente métaphore avec le Don Quichotte. Le Comité scientifique du colloque 4ème Congrès Philosophie(s) du Management à l’ESM-IAE sur le thème « Management et philosophies de l’Antiquité et nos évaluateurs , rappelons que seule de toutes les revues, nous procédons à 3 évaluations dont au moins une par un spécialiste qui n’est pas hexagonal, ont retenu 7 des 75 communications qui ont été présentées. Pour introduire ce numéro spécial enchâssé dans La RSG , et en partenariat avec notre consœur la RIPCO ( Revue Internationale de Psychosociologie et de Gestion des Comportements Organisationnels), nous avons confié à Baptiste Rappin le soin de l’orchestrer. Défendre une autre idée de la publication en management et son excellence, la vraie, pas celle de la bibliométrie et quelqu’autre re-construction du gigantisme de l’Armée rouge au nom de l’insertion dans des classements bidons, est bien notre « génome » ! « Une ressource n’a pas besoin d’être vantée, elle se mesure au profit que l’on peut en tirer. » Décidément, avec Aristote, nous pouvons conclure « s’il ne faut pas philosopher, il faut encore philosopher »
Appearance and spreading of common ragweed (Ambrosia artemisiifolia L.) in Bosnia and Herzegovina / Pojavljanje in širjenje ambrozije (Ambrosia artemisiifolia L.) v Bosni in Hercegovini
Authors: Bašić Fejzo , Đikić Mirha , Gadžo Drena 
Published: December 2017

It has been more than seven decades since the first data on the presence of common ragweed (Ambrosia artemisiifolia) in Bosnia and Herzegovina was published. The literature data show that this invasive weed species has spread and became naturalized in a major part of Bosnia and Herzegovina, and has a tendency of further spreading. It is believed that was introduced from the north and spread towards the south. Depending on the weather conditions, common ragweed occurs predominantly during the mid-spring and produces inflorescences from July until the first frost. The common ragweed plants can grow to be over 2 meters high. This species is very adaptive to different environmental conditions, and its fast expansion in the area of Bosnia and Herzegovina was favored by the increase of areas under uncultivated and abandoned land after the war. Since common ragweed is harmful both as a weed species and as an allergenic plant dangerous to human health, it is necessary to take all available measures to prevent its further spread, but also to reduce the number of populations in the areas where it is already established.Key words: common ragweed, invasive weeds, Bosnia and Herzegovina Pred več kot 70 leti so bili objavljeni prvi podatki o pojavu ambrozije (Ambrosia artemisiifolia) v Bosni in Hercegovini. Literaturni podatki kažejo, da se je ta invazivna vrsta razširila in postala običajna v večjem delu Bosne in Hercegovine in kaže da se bo širila še naprej. Velja prepričanje, da je bila uvedena in se širila od severa proti jugu. Odvisno od vremenskih razmer se ambrozija pojavlja predvsem sredi pomladi in se na njej razvijajo socvetja od meseca julija do prve slane. Rastline ambrozije lahko zrastejo do višine preko 2 m. Vrsta se zelo prilagaja različnim okoljskim razmeram, k njenemu širjenju na območju Bosne in Hercegovine je prispevalo v času vojne tudi širjenje neobdelanih in zapuščenih zemljišč. Ker je ambrozija škodljiva tako kot plevelna rastlina, kot rastlina, ki povzroča alergije in škoduje zdravju ljudi, je nujno izvajati ukrepe za preprečevanje nadaljnjega širjenja. Zelo pomembno pa je tudi zmanjševanje števila rastlin v populacijah, kjer je že razširjena.Ključne besede: ambrozija, invazivni pleveli, Bosna in Hercegovina
Značilnosti makrofitov in njihova vloga v vodnih ekosistemih / Characteristics of macrophytes and their role in aquatic ecosystems
Authors: Golob Aleksandra 
Published: December 2017

Makrofiti so rastline vodnih ekosistemov, ki jih vidimo s prostim očesom. Rastejo v vodi ali njeni neposredni bližini, in so lahko plavajoči in ukoreninjeni v substrat, prosto plavajoči, potopljeni in močvirski. V to skupino uvrščamo tudi makroalge, kot sta Chara in Nittella. Vodni makrofiti so zelo pomemben del vodnih ekosistemov. Na življenje v vodnem okolju so prilagojeni tako na morfološkem kot tudi na fiziološkem nivoju. Makrofiti so hrana za številne ribe in druge vodne živali ter predstavljajo življenjski prostor številnih vrst. Makrofiti varujejo rečne bregove pred erozijo. Privzemajo hranila in s tem vplivajo na kakovost vode. Značilnosti vodnih okolij, ki vplivajo na rast makrofitov, so svetloba, temperatura, hitrost toka, globina vode, vrsta sedimenta, kemizem vode in biološke interakcije.Ključne besede: značilnosti makrofitov, amfibijske rastline, helofiti, vodni ekosistemi Macrophytes are aquatic plants that can be seen by the unaided eye in water ecosystems. They grow in or near water and can be emergent (helophytes), submergent, or floating. Term includes the macroalgae like Chara and Nittella. Aquatic macrophytes are very important to healthy aquatic ecosystems. Macrophytes can be categorized based on where and how they grow in water. They are adapted to aquatic conditions on morphological and physiological level. Macrophytes provide a source of food for fish and wildlife and habitat for many species. They protect river banks from wave action and erosion. They absorb nutrients from the water and affect the quality of water. Characteristics of water environment that affect the growing of macrophytes are light, temperature, current velocity, depth of the water, type of sediment, chemistry of water, and biological interactions.Key words: properties of macrophytes, amphibious plants, helophytes, water ecosystems

Published: December 2017

Foi avaliado o efeito de níveis de proteína digestível - PD na dieta sobre o desempenho do acará-bandeira (Pterophyllum scalare). O delineamento foi inteiramente casualizado, composto por cinco tratamentos (30, 32, 34, 36 e 38% de PD) e quatro repetições, durante 60 dias. Foram utilizados 200 peixes, distribuídos em 20 aquários de 45l cada, em sistema de recirculação, com temperatura controlada e fotoperíodo de 12h. Os animais foram submetidos a uma dieta isoenergética 3200 Kcal.kg-1 de energia digestível e, contendo níveis crescentes de PD. Foram analisados os índices zootécnicos levando em consideração: ganho de peso, conversão alimentar aparente, taxa de eficiência proteica, taxa de crescimento específico e conversão alimentar aparente. Os resultados foram submetidos à análise de variância (ANOVA), seguida pelo teste de Tukey (P<0,05) e análise de regressão. Na avaliação dos índices zootécnicos, os animais alimentados com a dieta contendo 32% de PD apresentaram desempenho inferior aos demais. Os valores de 34, 36 e 38% de PD não diferiram entre si (P>0,05). Dessa forma, conclui-se que juvenis de acará-bandeira podem ser alimentados com 34% de PD sem comprometer o desempenho zootécnico, considerando o elevado custo associado à inclusão de proteína a níveis superiores.

The Verbal and Social Interaction Nursing Students questionnaire (VSI-NS) has been created to measure the development of verbal, social and interactional skills of nursing students with patients, from their perspective in nursing care. The aim of the present study was to determine the construct validity and internal consistency reliability of the questionnaire. The study had a methodological and developmental design and was carried out in four steps: adjustment of the items, face validity, data collection and data analysis. The number of items was reduced from 48 to 31. The factor analysis of the final 31 items resulted in four quite distinct factors: “Inviting to talk about feelings and thoughts”, “Building a caring relationship”, “Encouraging social and practical aspects in daily life” and “Caring towards health and wellbeing”. The results showed satisfactory psychometric properties in terms of content validity, construct validity and the internal consistency reliability of the questionnaire. It could be concluded that the original conceptual model could serve as a theoretical foundation to explain and understand nurses’ caring interactions with their patients.
Fixed Book Price Regimes

Fixed Book Price Regimes: Beyond the Rift between Social and Economic Regulation
Brazil is currently discussing the introduction of a nation-wide Fixed Book Price (“FBP”) policy, thus providing context for a discussion of its welfare benefits. There is a rift between the reasons for implementing FBP regimes, and those used to scrutinize them. In order for the debate surrounding the pros and cons of implementing FBP regimes to become more productive, one must investigate the links between the reasons for designing and enforcing such policies, on one side, and standard antitrust analysis, on the other. There are many interesting arguments at the table that both corroborate and compromise the case for an FPB policy. However, throughout history, these policies have experimented cognizable trends. The objective FBP regimes pursue and their design have changed subtly, yet relevantly throughout history. In our view, the current academic and public policy debate surrounding FBP regimes, in both countries considering adopting or revoking them, would benefit from an enhanced awareness of these trends and their policy implications. Ultimately, so would the antitrust analysis of these policies. We argue that a better grasp of these trends could potentially result in a more sober examination of the welfare risks associated with FBP policies.
French Constitution, Droit Administratif and the Civil Code

French Constitution, Droit Administratif and the Civil Code
Droit Administratif in France is a separate branch of law that exists in parallel to the civil and criminal law. The law has been developed from the concept of separation of powers that is ingrained in the French constitution. Its concepts derive from the Code civil that is implemented in France since its inception in the Napoleonic era and this has undergone reform that has made the role of the judges more interventionist. The highest administrative court is the Conseil d’État, which is at the apex of the machinery of administrative courts that are an important part of public law’s discourse and there is a hierarchy of courts that consider appeals and regulate the norms of conduct of state officials towards the citizens. The judges receive induction and training before taking on the role of occupation and that has been inculcated in the French administrative court judges. This article looks at the separate system of administrative law and its success in preserving the necessary checks and balances in the constitution, which it is intended to protect. This is an examination of the developing concept of French justice, the doctrine of separation of powers and civil procedural changes that enable the grievance of citizens against officials to be heard more expeditiously.
