Innovations in Sport Management: The Role of Motivations and Value Cocreation at Public Viewing Events
Authors: Woratschek Herbert , Durchholz Christian , Maier Christopher , Ströbel Tim
Published: February 2017

During mega-sport events, such as FIFA World Cup or Olympic Games, Fan Fests and other public viewing events have been developed as an innovative value proposition for watching sports. Those events attract millions of sport spectators worldwide. Event organizers have already realized
the tremendous economic potential, yet sport management literature provides little empirical evidence on this innovation in sport management. Therefore, this study investigates motivational drivers for sport consumption of public viewing events and provides a better understanding of innovation-induced
value cocreation at sport events. As public viewing represents an innovative mixture of stadium and television, we conduct a literature review of sport spectator motivations and study empirical findings in the stadium, television, and public viewing context. Based on this theoretical background
we conduct a quantitative analysis. During the UEFA EURO 2008TM in Austria and Switzerland, 498 spectators were interviewed using a standardized questionnaire at official public viewing events. The findings of this analysis reveal two new motivational dimensions for passive sport
consumption. Spectators of public viewing events enjoy the freedom to move around and the intercultural contact and therefore the chance to socialize with fan groups from different countries and cultures. Those new motivational dimensions represent key drivers of sport consumption behavior
in the context of public viewing events. In addition to those empirical findings, we derive practical implications in order to understand how innovations in sport management such as public viewing events open new ways to create value at sport events.
Fuzzy Numbers and Topsis for Analyzing Service Quality in the Mice Industry
Authors: Martín Juan Carlos , Román Concepción , Gonzaga Clara
Published: February 2017

This article presents a fuzzy logic approach in order to solve a multidimensional problem that evaluates the service quality of conferences held at the Technical University of Loja (UTPL) in 2013. In this way, an overall service satisfaction index for each conference is calculated allowing
for a final classification of the selected conferences. The theory of fuzzy sets is used by applying triangular fuzzy numbers (TFN) as a method to overcome some language problems (i.e., the ambiguity of the concepts that are associated with subjective judgments when measuring the service quality
with linguistic terms). Based on the concept of the degree of optimality, via the TOPSIS method, an overall performance service satisfaction index for each conference is developed. A set of 32 different dimensions have been used to assess the degree of satisfaction experienced by the conference
attendees, and the final classification shows that the performance of the conferences is not homogeneous as some of them perform better than others. This may be due to different factors, such as the central resources that the university provides for each conference, the quality of the articles
included in the conference, the key conference speakers, the different market segments that attended the conference, and other external factors. Studies on service quality in the MICE sector are still scarce in the literature as the majority of the literature on service quality in tourism
generally refers to hotels. As a result, our study aims to fill this gap. Our results allow the organizers and the central authorities of the university to identify the different dimensions needing improvement, which allows for a redirection and provision of general guidelines on how to effectively
respond to the comments, suggestions, and complaints from delegates. Furthermore, the study examines not only the functional quality attributes in the university, but also the quality attributes of the destination, such as the image of the city, transport connections to the airport, hotels,
restaurants, and the climate. Therefore, the city planners and administrators can also use the results to market Loja as an attractive destination in Ecuador for the MICE industry.
Assessing Economic Impact as a Means for Event Efficacy: A Proposed Model and Case Study
Authors: Testa Mark R. , Metter Michelle
Published: February 2017

Revenue generation for event planners traditionally comes from sponsorships, ticket and registration sales, merchandising, and additional income streams; however, these sources can at times be limited due to a lack of data and ability to substantiate an event's positioning within an
industry or marketplace. A variety of new methodologies exist for such agencies to generate funding, particularly through demonstration of economic impact. To date, many event planning organizations are not familiar with this process or the use of such data. The following provides a conceptual
model for understanding and engaging in economic impact analysis to secure traditional and new sources of funding. An overview of Tourism Improvement Districts (TID) is provided and a step-by-step process for utilizing the data is proposed. Finally, the San Diego Bay Wine & Food Festival
(SDBWFF) is used as a case study demonstrating the process.
How Might Chinese Medium Sized Cities Improve Competitive Advantage in the Event Tourism Market?
Authors: Zhou Chao (Nicole) , Qiao Guiqiang , Ryan Chris
Published: February 2017

Due to a limited brand presence and other issues, many Chinese second and third tier cities find it hard to compete with larger cities to attract, host, and promote mega-events. The purpose of this study is to understand the gap between the large and medium-sized cities and find how
the smaller cities may develop their own product potential in the MICE market. The article reports results from a qualitative research study based on interviews with 40 business attendees from three medium-sized cities of Zhejiang Province, China. The results indicated a series of related
dimensions, but a new pattern of "hosting capability" can be discerned whereby business attendees are aware of the product offered by the smaller-sized cities but perceive that their competitive advantage is weak, primarily due to a poor brand presence.
Characterization and Modeling of Contamination for Lyman Break Galaxy Samples at High Redshift
Authors: Vulcani Benedetta , Trenti Michele , Calvi Valentina , Bouwens Rychard , Oesch Pascal , Stiavelli Massimo , Franx Marijn
Published: February 2017

The selection of high-redshift sources from broadband photometry using the Lyman-break galaxy (LBG) technique is a well established methodology, but the characterization of its contamination for the faintest sources is still incomplete. We use the optical and near-IR data from four (ultra)deep Hubble Space Telescope legacy fields to investigate the contamination fraction of LBG samples at

selected using a color–color method. Our approach is based on characterizing the number count distribution of interloper sources, that is, galaxies with colors similar to those of LBGs, but showing detection at wavelengths shorter than the spectral break. Without sufficient sensitivity at bluer wavelengths, a subset of interlopers may not be properly classified, and contaminate the LBG selection. The surface density of interlopers in the sky gets steeper with increasing redshift of LBG selections. Since the intrinsic number of dropouts decreases significantly with increasing redshift, this implies increasing contamination from misclassified interlopers with increasing redshift, primarily by intermediate redshift sources with unremarkable properties (intermediate ages, lack of ongoing star formation and low/moderate dust content). Using Monte-Carlo simulations, we estimate that the CANDELS deep data have contamination induced by photometric scatter increasing from

at

to

at

for a typical dropout color

mag, with contamination naturally decreasing for a more stringent dropout selection. Contaminants are expected to be located preferentially near the detection limit of surveys, ranging from 0.1 to 0.4 contaminants per arcmin2 at

 = 30, depending on the field considered. This analysis suggests that the impact of contamination in future studies of

galaxies needs to be carefully considered.

We explore the nucleus of the nearby 109

 early-type galaxy, NGC 404, using Hubble Space Telescope (HST)/STIS spectroscopy and WFC3 imaging. We first present evidence for nuclear variability in UV, optical, and infrared filters over a time period of 15 years. This variability adds to the already substantial evidence for an accreting black hole at the center of NGC 404. We then redetermine the dynamical black hole mass in NGC 404 including modeling of the nuclear stellar populations. We combine HST/STIS spectroscopy with WFC3 images to create a local color–M/L relation derived from stellar population modeling of the STIS data. We then use this to create a mass model for the nuclear region. We use Jeans modeling to fit this mass model to adaptive optics stellar kinematic observations from Gemini/NIFS. From our stellar dynamical modeling, we find a 3σ upper limit on the black hole mass of

. Given the accretion evidence for a black hole, this upper limit makes NGC 404 the lowest mass central black hole with dynamical mass constraints. We find that the kinematics of H2 emission line gas show evidence for non-gravitational motions preventing the use of gas dynamical modeling to constrain the black hole mass. Our stellar population modeling also reveals that the central, counter-rotating region of the nuclear cluster is dominated by ∼1 Gyr old populations.
The Galactic Center: A Petaelectronvolt Cosmic-ray Acceleration Factory
Authors: Guo Yi-Qing , Tian Zhen , Wang Zhen , Li Hai-Jin , Chen Tian-Lu
Published: February 2017

The multiteraelectronvolt γ-rays from the galactic center (GC) have a cutoff at tens of teraelectronvolts, whereas the diffuse emission has no such cutoff, which is regarded as an indication of petaelectronvolt proton acceleration by the HESS experiment. It is important to understand the inconsistency and study the possibility that petaelectronvolt cosmic-ray acceleration could account for the apparently contradictory point and diffuse γ-ray spectra. In this work, we propose that the cosmic rays are accelerated up to greater than petaelectronvolts in the GC. The interaction between cosmic rays and molecular clouds is responsible for the multiteraelectronvolt γ-ray emissions from both the point and diffuse sources today. Enhanced by the small volume filling factor (VFF) of the clumpy structure, the absorption of the γ-rays leads to a sharp cutoff spectrum at tens of teraelectronvolts produced in the GC. Away from the GC, the VFF grows, and the absorption enhancement becomes negligible. As a result, the spectra of γ-ray emissions for both point and diffuse sources can be successfully reproduced under such a self-consistent picture. In addition, a “surviving tail” at ∼100 TeV is expected from the point source, which can be observed by future projects CTA and LHAASO. Neutrinos are simultaneously produced during proton-proton (PP) collision. With 5–10 years of observations, the KM3Net experiment will be able to detect the petaelectronvolt source according to our calculation.
WOMBAT: A Scalable and High-performance Astrophysical Magnetohydrodynamics Code

Published: February 2017

We present a new code for astrophysical magnetohydrodynamics specifically designed and optimized for high performance and scaling on modern and future supercomputers. We describe a novel hybrid OpenMP/MPI programming model that emerged from a collaboration between Cray, Inc. and the University of Minnesota. This design utilizes MPI-RMA optimized for thread scaling, which allows the code to run extremely efficiently at very high thread counts ideal for the latest generation of multi-core and many-core architectures. Such performance characteristics are needed in the era of “exascale” computing. We describe and demonstrate our high-performance design in detail with the intent that it may be used as a model for other, future astrophysical codes intended for applications demanding exceptional performance.
Constraints on the Progenitor of SN 2016gkg from Its Shock-cooling Light Curve

SN 2016gkg is a nearby SN IIb discovered shortly after explosion. Like several other Type IIb events with early-time data, SN 2016gkg displays a double-peaked light curve, with the first peak associated with the cooling of a low-mass extended progenitor envelope. We present unprecedented intranight-cadence multi-band photometric coverage of the first light curve peak of SN 2016gkg obtained from the Las Cumbres Observatory Global Telescope network, the Asteroid Terrestrial-impact Last Alert System, the Swift satellite, and various amateur-operated telescopes. Fitting these data to analytical shock-cooling models gives a progenitor radius of ∼40–150

with ∼2–40 × 10−2

of material in the extended envelope (depending on the model and the assumed host-galaxy extinction). Our radius estimates are broadly consistent with values derived independently (in other works) from HST imaging of the progenitor star. However, the shock-cooling model radii are on the lower end of the values indicated by pre-explosion imaging. Hydrodynamical simulations could refine the progenitor parameters deduced from the shock-cooling emission and test the analytical models.

« Expats », « installés » et « pionniers » : mobilités contemporaines, mondes sociaux et dynamiques postcoloniales des Français en Algérie
Authors: Fabbiano Giulia
Published: February 2017

Jusqu’à son indépendance, l’Algérie a été le pays d’Afrique du Nord le plus concerné par la présence étrangère en provenance de la rive nord de la Méditerranée. Aujourd’hui, à la différence de ses voisins, elle peine à être considérée comme un espace migratoire mixte accueillant une population étrangère, qui plus est d’origine européenne. Or, à partir de l’année 2000, le retour de la sécurité après la guerre civile des années 1990, combiné à l’ouverture libérale de l’économie nationale, inaugure une nouvelle phase dans la mobilité en provenance de la rive nord de la Méditerranée, et plus particulièrement de la France et de l’Espagne. Si un certain nombre de ressortissants hexagonaux qui avaient été obligés de fuir le pays entre 1993 et 1995 ont pu revenir en Algérie, de nouveaux acteurs, aux profils variés, ont également franchi la mer, s’installant dans les deux plus grandes villes du pays : Alger et Oran. S’appuyant sur une enquête ethnographique de longue durée principalement menée dans la capitale, cet article souhaite attirer l’attention sur ces mobilités contemporaines : présenter le cadre spécifique et ses dynamiques postcoloniales, souligner les imaginaires et les pratiques quotidiennes dans l’interaction avec la société locale, proposer une cartographie de « mondes sociaux » rendant compte de la diversité des manières d’être Français en Algérie.
La mobilité des travailleurs espagnols dans l’ouest de l’Algérie
Authors: Sempere Souvannavong Juan David , Cabezón Fernández María-Jesús
Published: February 2017

L’Algérie enregistre depuis le début des années 2000 une forte croissance économique. À l’inverse, en Espagne, la crise qui sévit depuis 2009 a mis fin à une longue période de prospérité, entraînant l’effondrement de pans entiers de l’économie et faisant bondir les chiffres du chômage. Cette situation a déclenché une forte augmentation de l’émigration espagnole. Comme au xix e siècle, la précarité dans laquelle se retrouve une partie de la population espagnole et les opportunités professionnelles sont autant de facteurs qui ont permis le développement d’une présence et d’une mobilité espagnole en Algérie. Il s’agit d’entreprises et de travailleurs de nombreux secteurs productifs et particulièrement de la construction et du BTP. Travailler et vivre en Algérie comporte de nombreux avantages pour les Espagnols, notamment liés à la proximité entre les deux pays ; cela va également de pair avec des difficultés administratives et une certaine vulnérabilité juridique et économique.
Nouvelles migrations ? Les Français dans les circulations migratoires européennes vers le Maroc
Authors: Peraldi Michel , Terrazzoni Liza
Published: February 2017

Cet article s’intéresse aux migrations françaises vers le Maroc. Aux « expatriés » mandatés par leurs États ou leurs entreprises, vivant à distance de la société locale et bénéficiant de privilèges socio-économiques institutionnellement garantis, se substituent des migrants, issus des classes moyennes, en partie affaiblies en France, qui négocient eux-mêmes, sans médiateur institutionnel ou économique, les conditions de leur mobilité. Cet article décrit les itinéraires de ces Français, les circonstances qui impulsent leur mobilité ainsi que les conditions dans lesquelles elles s’opèrent. Il met en évidence les conditions d’informalité qui marquent certaines de leurs expériences au Maroc ainsi que leur inscription dans un espace-temps transnational.
Migrants européens dans la ville de Saint-Louis du Sénégal : des stratégies hétérogènes pour négocier sa place dans la cité
Authors: Louveau Frédérique
Published: February 2017

Cet article porte sur la manière dont les migrants européens installés dans la ville de Saint-Louis du Sénégal utilisent ses ressources patrimoniales et culturelles pour y construire leur style de vie. La mixité sociale forme un « monde » où les retraités s’investissent dans le tourisme avec un romantisme fondé sur la nostalgie coloniale et l’époque des comptoirs, tandis que les jeunes souhaitent effacer ces références historiques. Ils désirent tous être des acteurs du développement, selon leur définition propre. Les premiers s’adonnent à leurs passions créatives en animant la ville pour attirer les touristes et éduquer la population à la sauvegarde du patrimoine. Les seconds jouissent de ces activités en compagnie des Sénégalais convaincus que le développement dépend de rapports égalitaires.
Les migrants européens du littoral sénégalais (Petite Côte, Saloum) : ouverture de l’économie touristique et entre-soi identitaire
Authors: Quashie Hélène
Published: February 2017

Cet article propose d’analyser les mobilités du tourisme résidentiel et les migrations professionnelles qui s’y rattachent, en provenance d’Europe vers deux régions littorales du Sénégal. Ces circulations répondent en partie aux difficultés de la crise économique que rencontrent leurs protagonistes en Europe, retraités comme actifs. Ces mobilités résidentielles et entrepreneuriales renouvellent les dynamiques touristiques à une échelle locale et internationale et favorisent l’ouverture économique de la Petite Côte et du Saloum. Cependant, les activités concernées reposent sur des réseaux de sociabilité bâtis selon des mécanismes de distinction sociale. Des processus de ségrégation, d’ethnicisation et de racialisation s’appuient en effet sur des inégalités de classe entre résidents européens et sénégalais. Les premiers tendent à se replier sur un entre-soi fragile et ambivalent, qui perdure grâce à sa constante recomposition.
Crise économique et migrations de retour. Le cas des Équatoriens en Espagne
Authors: Perraudin Anna
Published: February 2017

Le « retour » des migrants dans leur pays d’origine sous l’effet des crises économiques fait aujourd’hui l’objet d’un fort intérêt médiatique, politique et scientifique. En dépit de son apparente évidence, le phénomène, posé comme caractéristique de la réactivité des flux migratoires contemporains, est complexe. L’Espagne, où le solde migratoire est négatif depuis 2011, est à ce titre un bon point d’observation. Cet article propose une synthèse des principaux travaux publiés sur ce cas d’étude, afin d’appréhender les enjeux méthodologiques et politiques que soulève l’analyse des retours. À partir d’une revue de la littérature, l’article explore trois dimensions : les limites de la mesure statistique du phénomène, les politiques des États d’origine et de réception, et les stratégies des migrants conditionnées par les stratifications de classe, de genre et de statut migratoire.
La masculinité au travail au sein d’un groupe réflexif pour hommes auteurs de violence contre des femmes
Authors: Billand Jan , Molinier Pascale
Published: February 2017

Nous décrivons et analysons les effets subjectifs du travail consistant à organiser et animer un « groupe réflexif pour hommes auteurs de violence contre des femmes », au Brésil, à partir d’observations ethnographiques et d’entretiens réalisés auprès des trois « facilitateurs » (hommes). Pour ne pas être excessivement affectés dans leur rapport à la masculinité et aux autres hommes, les facilitateurs mettent en place deux stratégies conscientes : une politisation de leur rapport à la masculinité et aux autres hommes, et une division du travail du care impliquant qu’ils ne se soucient que des hommes auteurs de violence, et non des femmes victimes. Nous discutons les implications de ces résultats pour les chercheurs et les praticiens engagés dans la prévention des violences conjugales.
L’économie comme science et les jugements de valeur politiques
Authors: Barbaroux Nicolas , Bellet Michel
Published: February 2017

La thèse méthodologique initiale de Gunnar Myrdal, qui structure en particulier son ouvrage critique de 1930, est méconnue, au profit d’une thèse ultérieure qui avance que la théorie économique est irradiée dans son intégralité par les jugements de valeur (non-neutralité stricte). Cette première thèse, dite de neutralité entre science et jugements de valeur, semble proche de celle de Lionel Robbins et paraît contradictoire avec l’engagement politique de Myrdal et avec son intérêt pour la légitimation de politiques budgétaires et monétaires au cours des années 1930 et 1940. Elle est liée à l’influence de la philosophie suédoise d’Axel Hägerström, qui apparaît comme un type spécifique de néopositivisme. Pour autant, l’usage de cette philosophie, avec ses implications méthodologiques, conduit au contraire Myrdal à fonder le lien entre économie et politique, et ainsi à créer une connexion relative entre science et interventions pratiques incorporant fatalement des jugements de valeur, à l’aide de ce qu’il appelle une technologie de l’économie. Malgré un certain nombre de difficultés, Myrdal va tenir cette ligne jusqu’à, progressivement, adopter une thèse de non-neutralité, dominante dans les années 1940 et souvent associée alors à un type d’institutionnalisme. Le contenu de la première phase myrdalienne, revendiquant une thèse non cognitiviste et une thèse émotiviste, avec un rôle reconnu aux intérêts des groupes sociaux et aux pouvoirs, est donc ici particulièrement analysé. Cet examen permet de donner un sens nouveau à l’évolution des positions de Myrdal et de rapprocher le Myrdal perçu du Myrdal effectif, en avançant l’hypothèse d’un passage d’une position de faible neutralité à une position ambiguë proche de la faible non-neutralité.

Marchés et allotissement : regroupement ou dégroupement ?
Authors: Compte Olivier , Lamy Laurent , Laurent Emmanuel
Published: February 2017

On considère des marchés pouvant faire l’objet d’un allotissement : les biens peuvent être découpés en lots plus ou moins hétérogènes. On s’intéresse à la question de l’allotissement optimal, du point de vue du vendeur (ou du maître d’œuvre), en se focalisant sur l’effet de regrouper plusieurs lots en un seul, ou inversement, de dégrouper un lot initial en plusieurs lots distincts. On identifie deux effets. Un dégroupement accroît toujours l’efficacité de l’allocation finale. Cependant, il modifie la nature des asymétries entre enchérisseurs, et cela peut conduire à des conditions concurrentielles plus ou moins défavorables. Deux applications sont discutées : les appels d’offres de services de flux bancaires et les enchères pour allouer l’espace publicitaire sur Internet. Classification JEL  : D44.
Paludisme et anémie des enfants en Afrique subsaharienne : effet de la distribution de moustiquaires
Authors: Apouey Bénédicte , Picone Gabriel , Wilde Joshua , Coleman Joseph , Kibler Robyn
Published: February 2017

Cet article évalue l’effet de différentes politiques de lutte contre le paludisme, et en particulier de la politique dite de « mise à l’échelle » de la distribution de moustiquaires, sur la probabilité d’anémie des enfants en Afrique subsaharienne. Les données combinent des informations individuelles sur plus de 150 000 enfants et leur famille, et des informations régionales sur l’intensité du paludisme avant le lancement des campagnes, pour seize pays, entre 2000 et 2014. La méthode utilisée est celle des doubles différences, qui teste si les politiques ont entraîné une baisse plus forte de l’anémie dans les régions où l’intensité du paludisme était plus élevée. Les résultats indiquent que la mise à l’échelle a un effet faible ou négligeable sur la probabilité d’anémie modérée ou sévère, tandis que les autres politiques n’ont pas d’effet significatif.

Forger un « consensus schizophrène »
Authors: Buchner Michael
Published: February 2017

L’article souligne l’importance d’une série de colloques organisés par Robert Triffin après l’entrée en vigueur du système monétaire européen en 1979. D’une part, on peut y observer l’émergence d’un réseau influent dont certains membres joueront un rôle important dans les préliminaires des négociations du traité de Maastricht. D’autre part, l’approche pragmatique qui prédomine dans ces débats permet de consolider un « savoir économique » visant davantage à la « faisabilité » politique qu’à la rigueur scientifique. Dans la mesure où ces économistes vont même jusqu’à soutenir des idées politiques ne correspondant pas à leurs convictions économiques, ce consensus peut également se révéler « schizophrène », selon l’expression de Triffin.

L’échec d’un projet de spin-off universitaire. Ou la quête incomplète de légitimité
Authors: Francois Valérie , Philippart Pascal
Published: February 2017

Pour toute entreprise émergente, la recherche de légitimité est fondamentale. Plus spécifiquement pour un projet de spin-off universitaire, cette quête de légitimité doit s’exercer auprès de plusieurs types de parties prenantes et dans toutes les dimensions de la légitimité. Notre analyse porte sur un cas d’échec d’un projet de spin-off universitaire. Le cadre théorique de la légitimité nous a permis de comprendre les raisons d’un tel échec, en soulignant notamment l’importance de la dimension morale de la légitimité auprès de certaines parties prenantes.

L’expression de soi et les réseaux sociaux
Authors: Lee Sang-Hoon , Kim Yo-Han
Published: February 2017

Les médias intelligents et les réseaux sociaux facilitent le contact entre les utilisateurs et créent une puissante relation sociale basée sur l’efficacité, l’immédiateté et la mobilité. Mais cette facilité peut causer un autre problème en ayant changé la manière de communiquer. L’analyse est ici centrée sur les pratiques des étudiants universitaires coréens via des entretiens se résumant en trois grandes parties. Premièrement, leur utilisation des réseaux sociaux vise à laisser une trace de leur vie quotidienne. Deuxièmement, ils utilisent ce service pour le partage et la communication de leur vie quotidienne avec autrui, amis et étrangers. La dernière raison de l’usage du réseau social vise à obtenir l’attention ou l’appui de leurs amis et connaissances. Selon les études, le soutien social perçu encourage l’esprit communautaire. Ce dernier est défini comme le sentiment d’appartenance à des groupes sociaux ayant des caractéristiques similaires. Les utilisateurs qui mettent à jour leurs statuts sur les réseaux sociaux sentent plus de liens et de sentiments d’appartenance avec les autres utilisateurs. L’appui social et l’esprit communautaire sont des éléments essentiels qui contribuent au bien-être psychologique et à la satisfaction de la vie.
Using Ethical Frameworks in Times of Transition and Uncertainty
Authors: Sullivan-Marx Eileen M.
Published: February 2017

Health care policy is never easy and always fraught with concerns about quality, access, and cost. Currently, uncertainty abounds regarding new federal and state policies on the horizon for older adult care and quality. Empirics undergird most policy-making decisions regarding risk/benefit, cost, and knowing the best action to put in place for the best results. However, in times of great change in policy direction and political viewpoints, empirical knowledge must be combined with ethical knowledge for planning and implementation. Ethical and moral judgment has long been a mainstay of nursing practice and organizational leadership. Using ethical knowledge as a framework will be a crucial guide for nurses and health professionals and society to prioritize action and decisions in policy. [

The European hake, Merluccius merluccius, is an important resource for Mediterranean fisheries. This study focuses on juvenile and adult hake feeding ecology in the Gulf of Lions, using information from scientific surveys carried out during two seasons and three years (2004-2006). Stomach content and stable isotope (δ15N, δ13C) analyses were performed, and the main factors explaining variations in δ15N were investigated using GLMs. In the Gulf of Lions, hake mostly fed on crustaceans and fish and a dominant piscivorous regime was reached at 15 cm total length. Pelagic fish (sardine, anchovy and small blue whiting) were the main source of prey (40%-80%) and cannibalism was low (< 5%). The results confirmed that hake is an opportunistic feeder and also showed that the size and diversity of prey vary among hake size classes, probably as a result of the different spatial distribution and/or foraging migrations. The present study finally postulates that the unbalanced sex ratio (80% female against 20% male) observed at the adult stage could be related to the combination of growth pattern differences, diet and exploitation rate on the continental shelf, where the males spend a longer period of time.

In recent years, presenting the useful information in an effective way has become a great necessity for educators. The opportunities provided by the AR technologies offer practical ways to meet this need of educators. By integrating the digital objects with real-world assets simultaneously, AR helps to concretize abstract concepts, and enhances the sense of reality, which in turn is a huge contribution to learning. In this chapter, it was presented the various limitations and advantages of AR revealed by some empirical studies in the literature. In addition, it was given information about AR development tools/ programs, add-on packages and presented development stages for an exemplary AR book page. The use of the Unity and Vuforia was explained as the development tools. It is believed that this information would be useful for those who will develop AR application which can be easily displayed by mobile or desktop PCs.

The aim of this study is to analyze success in e-learning with data mining methods and find out potential patterns. In this context, 374.073 data of 2013-14 period taken from an institution serving in e-learning field in Turkey are used. Data set, which is collected from information technology, banking and pharmaceutical industries, includes success and industry of employees', trainings which they complete, whether the trainings are completed, first login and last logout dates, training completion date and duration of experience in training. Using this data set, success status of participants is observed by using data mining methods (C5.0, Random Forest and Gini). By observing using accuracy, error rate, specificity and f- score from performance evaluation criteria, C5.0 has chosen the algorithm which gives the best performance results. According to the results of the study, it has been determined that the sectors of the employees are not important, on the contrary the ones that are important are the completion status, the duration of experience and training.
Gendered Violence and Victim-Blaming
Authors: Sweeny JoAnne
Published: February 2017

Cyber-harassment and Revenge pornography are international problems that can cause psychological, financial and physical harm to their victims. And yet, despite legal efforts in several countries, the law has yet to fully address these issues. Instead, enactment and enforcement of laws is undermined by the gendered nature of these acts, which leads to (typically male) police and prosecutors to treat victims with ambivalence and even scorn. This article shows that, despite the prevalence and dangers involved with cyber-harassment and revenge porn, victims are still often left without redress. This article also analyzes law enforcement's tendency to minimize victims' harm and blame victims for their own suffering. Finally, this article discusses how perceptions may begin to change, which could lead to a better understanding of the full range of behaviors and effects of cyber-harassment and revenge pornography and, consequently, better legal outcomes for victims.
The Malevolent Side of Revenge Porn Proclivity
Authors: Pina Afroditi , Holland James , James Mark
Published: February 2017

This paper presents a novel study, exploring a form of technology facilitated sexual violence (TFSV) known as revenge porn. Despite its emerging prevalence, little is known about the characteristics of revenge porn perpetrators. In the current study, a revenge porn proclivity scale was devised to examine participants' behavioural propensity to engage in revenge porn. One hundred adults, aged 18-54, were recruited online from a community sample. The correlational relationship between revenge porn proclivity and the self-reported endorsement of the Dark Triad, sadism, and ambivalent sexism was examined. Additional proclivity subscales of revenge porn enjoyment and revenge porn approval were also created. The study's main findings revealed a positive correlation between a greater behavioural propensity to engage in revenge porn and higher levels of the Dark Triad and ambivalent sexism. Moreover, endorsement of psychopathy was found to be the only Dark Triad trait that independently predicted revenge porn proclivity. The results suggest that perpetrators of revenge porn may have distinct personality profiles. Limitations and directions for future research are discussed.
Assessment of the Availability of Forest Biomass for Biofuels Production in Southwestern Portugal

Published: February 2017

In 2014, Portugal was the seventh largest pellets producer in the World. Since the shortage of raw material is one of the major obstacles that the Portuguese pellets market faces, the need for a good assessment of biomass availability for energy purposes at both country and regional levels is reinforced. This work uses a Geographical Information System environment and remote sensing data to assess the availability and sustainability of forest biomass residues in a management unit with around 940 ha of maritime pine forest. The period considered goes from 2004 to 2015. The study area is located in Southwestern Portugal, close to a pellets factory; therefore the potential contribution of the residual biomass generated in the management unit to the production of pellets is evaluated. An allometric function is used for the estimation of maritime pine above ground biomass. With this estimate, and considering several forest operations, the residual biomass available was assessed, according to stand composition and structure. This study shows that, when maritime pine forests are managed to produce wood, the amount of residues available for energy production is small (an average of 0.37 t ha-1 year-1 were generated in the study area between 2004 and 2015). As a contribution to the sustainability of the Portuguese pellets industries, new management models for maritime pine forests may be developed. The effect of the pinewood nematode on the availability of residual biomass can be clearly seen in this study. In the management unit considered, cuts were made to prevent dissemination of the disease. This contributes to a higher availability of forest residues in a specific period of time, but, in the medium term, they lead to a decrease in the amount of residues that can be used for energy purposes.
