Résumé Les premiers services d’urgences sont nés il y a une trentaine d’années pour réguler l’accès à l’hôpital des patients qui arrivaient de façon imprévue et sans conditionnement médical satisfaisant dans les services hospitaliers. Au cours du temps, ils ont été progressivement perçus par la population et les interlocuteurs professionnels (médecine de ville, police, justice, associations, services sociaux, etc.) comme un recours capable de régler rapidement de nombreuses situations réellement urgentes ou seulement imprévues. Accessibles à tous, les services d’urgences constituent une des entrées privilégiées du système de soins dont ils sont en première ligne. Ils permettent la prise en charge continue et simultanée de plusieurs patients de gravité variable, et ce, jour et nuit. De ce fait, les urgentistes sont entraînés à aller à l’essentiel par la prise immédiate et simultanée de décisions diagnostiques et thérapeutiques concernant des patients à différents stades de leur évolution clinique. Les informations pour y parvenir ne sont ni toujours évidentes à rassembler au milieu de la fragmentation des patients de la médecine moderne (d’organes et de spécialités), ni la plupart du temps complètes. Ces données nécessitent une réactualisation permanente amenant une grande densité d’informations à gérer en urgence. À cela s’ajoute un flux de patients continu susceptible de constituer un engorgement de l’espace de travail et qui justifie à lui seul qu’aucun patient ne meure officiellement aux urgences – ce qui bloquerait la salle d’examen pour plusieurs heures – mais dans l’unité d’hospitalisation de courte durée ( uhcd ) généralement attenante aux urgences.

Résumé Ces dernières décennies, les conditions du rapport à la mort se sont profondément transformées dans le champ de la médecine, suite aux innovations thérapeutiques, à l’invention de techniques de maintien en survie (réanimation, respiration et alimentation artificielles) et plus largement à l’émergence de la « fin de vie » comme période distincte et susceptible d’une intervention spécifique. Par ailleurs, l’apparition de préoccupations nouvelles liées à l’autonomie, à l’information et aux droits des malades a largement participé à l’ensemble de ces évolutions qui permettent de mieux comprendre le développement d’une médecine palliative particulièrement représentative de ces mutations. Ce texte entend rendre compte d’une partie de ce travail de recomposition des normes et des valeurs à l’œuvre dans le cadre de cette discipline spécialisée dans la prise en charge des patients confrontés à la mort. Il s’agit de voir notamment comment, au sein des unités hospitalières (les unités de soins palliatifs), cette recomposition est à mettre en lien avec l’idéologie et les croyances professionnelles spécifiques au monde des soins palliatifs 1 (Castra, 2003). Dans cette perspective, on s’intéressera dans ce qui suit au travail des professionnels à l’approche de la mort et à la gestion de l’incertitude dans les fins de trajectoires de maladies chroniques. Les croyances et les valeurs sur lesquelles repose l’émergence de ce nouveau modèle de gestion du mourir doivent être recherchées dans l’idéal d’une mort acceptée et pacifiée qui prédomine dans le champ des soins palliatifs. De ce point de vue, l’étude de ces situations limites est assez caractéristique de l’apparition de normes du « bien mourir » qui sous-tendent le comportement des différents acteurs, notamment médicaux. Afin d’explorer cette normativité à l’œuvre, on s’attachera notamment à montrer que la pratique palliative est dominée par un travail interprétatif qui vient structurer les modalités de prise de décision et les pratiques médicales ou soignantes en situation terminale.

Résumé On entend de nos jours par « euthanasie » la recherche d’une mort douce lorsque tout espoir de guérison a disparu ; cette définition nous est héritée de Bacon. Et l’on pense souvent, guidé en cela par l’étymologie du mot, pouvoir faire remonter jusqu’à l’Antiquité la pratique de l’euthanasie. Mais c’est lui accorder à la fois trop et trop peu : la signification moderne du mot se distingue nettement de ses rares emplois antiques, même si on trouve bien le terme, ou des pratiques correspondant à ce que nous appellerions « euthanasie », dans l’Antiquité. Or, c’est en prenant des exemples issus de l’Antiquité que Bacon initia l’usage moderne du terme, de ce qu’il appelle l’ euthanasia exterior 1 . Nous voudrions ici montrer en quoi le mot « euthanasie » recouvre des sens fort différents selon l’époque ; et aussi tenter d’expliquer comment sa signification moderne a pu s’élaborer sur des références antiques.

To Boldly Go
Authors: Nettleton Kimberely Fletcher
Published: November 2014

In an effort to help special needs students in the classroom, many teachers work very hard to differentiate curriculum for their struggling students. According to A Nation Deceived (Colangelo, Assouline, & Gross, 2004), the one group of students in American schools who make little or no yearly progress are the gifted students in the classroom. Enriching the curriculum for gifted students does not appear to be a high priority for teachers (Horne & Shaughnessy, 2013). Increasingly, teachers turn to the computer to provide independent work for students, relegating education to a solitary endeavor. Social skills and collaboration are traits encouraged in many classrooms. Instead of isolating gifted students, technology can be integrated into instructional strategies in order to enrich the curriculum for all students. Enrichment can become an integral part of instruction. Technology can create learning environments that challenge gifted students.
Showcasing the Creative Talents in Science of the Academically Less-Inclined Students through a Values-Driven Toy Storytelling Project
Authors: Amir Nazir
Published: November 2014

It has been mentioned that gifted students may not necessarily just be the ones who have high IQ and perform consistently well in their examinations but also those who are able to showcase their creative talents through content and skills gained in their academic subjects. This chapter highlights how a class of academically less-inclined students in Singapore has been able to showcase their creative talents in science and other subjects through a values-driven toy storytelling project that serves a community need. Results from this study show that the project has provided an avenue for the students' creative talents in science and other subjects to be recognized by members of the community. The positive recognition through the students' work instilled a sense of pride and self-worthiness amongst them.
Differentiation 2.0
Authors: Beasley Jennifer G. , Imbeau Marcia B.
Published: November 2014

This case study highlights the essential components of differentiating instruction to meet the needs of all students, including those most advanced, and English Language Learners by using a variety of technologies. Many teachers in the study had access to technology, but few received limited professional development. Roadblocks that many teachers encountered are identified with possible solutions for addressing those concerns. The recommendations provided for addressing concerns that classroom teachers face are (1) how to differentiate instruction for all learners, (2) how to learn and sustain growth in using the tools of technology in lesson planning and implementation, and (3) how to manage all of the various components so that chaos does not ensue and every students' learning is maximized. A review of all of these issues can be beneficial to other teachers in heterogeneous classrooms who want to use technology as tool for differentiating instruction.
Geospatial Analysis of Neighborhood Characteristics and Access to Fresh Produce
Authors: Ogneva-Himmelberger Yelena , Meng Fei
Published: November 2014

A growing number of studies have shown that adequate spatial access to healthy foods leads to increased fresh produce consumption and reduced risk of chronic diseases. Annual dynamics of spatial access to 1,539 vendors of fresh produce (including farmers markets and roadside farm stands) are analyzed in Massachusetts. Travel distance to the nearest fresh produce vendor was calculated for each census block group using GIS and dasymetric mapping. Spearman's rank order correlation coefficient was calculated to test whether the association between neighborhood characteristics and the travel distance to the nearest vendor existed and if it was statistically significant in urbanized and rural areas. Results show that during summer, median travel distance to the nearest fresh produce vendor decreases 20% in rural areas and 9% in urbanized areas. The shortest travel distances are associated with the most disadvantaged neighborhoods in both rural and urbanized settings. Further research is needed to examine if the same association holds true in other parts in the country.
Towards Availability

Published: November 2014

With the on-demand ability of cloud computing, the performance requirement of a cloud application can be satisfied by adding a certain amount of computing resources to or removing some from the application in response to the workload fluctuation. However, the problem of the availability of application influenced by VM-based physical relative locations during resource scaling process is a challenge and has not been widely discussed yet. In this paper, the authors present a novel availability-based computing model to describe availability attribute of one application in the hierarchical topology of clouds. Moreover, the authors propose an availability-aware scaling mechanism by performing both vertical and horizontal resizing to explore how and where to allocate computing resource. Simulation results indicate that our model captured the availability of cloud applications properly and the proposed dynamic scaling approach achieves the objectives of meeting availability demands and minimizing the total cost.
Peer-to-Peer Orchestration of Web Mashups
Authors: Haque Abul Ahsan Md Mahmudul , Yu Weihai
Published: November 2014

Web mashups are web applications built on top of external web services through their open APIs. As mashups are becoming increasingly complex, there is a need for systematic support for their development and orchestration. This paper presents a peer-to-peer approach to mashup orchestration where a network of agents carries out orchestration using continuation-passing messaging. The approach supports exception handling and recovery. Our experimental results show clear performance gains of the approach over traditional centralized orchestration in service-oriented computing and orchestration done by application servers hosting mashups.

The Identity Salience and Emotional Attachment Strategies in Alumni-University Relationships
Authors: Min Junhong , Segal Madhave N. , Dalman M. Deniz
Published: November 2014

Higher education has never truly recognized the importance of garnering the resources of alumni by expending university efforts in developing, controlling, and maintaining relationships with alumni. The purpose of this research is to tackle the long-term relationship marketing question. Drawing on the social marketing and relationship marketing literature, the authors propose and empirically test the roles of two relationship marketing strategies, namely identity salience and emotional attachment, in the alumni-university relationship. While the identity salience strategy encourages alumni to connect their identity to their former university, the emotional attachment strategy triggers the psychological ownership that leads alumni to proactively engage in university activities. Based on results of data collected from a large Midwestern university, the identity salience strategy was found to greatly affect symbolic consumption behavior while the emotional attachment strategy was found to strongly promote relationship-specific volunteering. The results also revealed that three social benefits, including development of a business network, enhancement of a friendship network, and enjoyment of participation, are associated with the two relationship marketing strategies. The authors conclude with a discussion addressing limitations of the study as well as practical and theoretical implications of the findings.

Authors: Al-Hakim Latif , Morgan Melissa Johnson , Chau Roberta
Published: November 2014

This study investigates cross-border collaboration between beef organisations in Australia and Singapore. It aims to identify factors impacting trust and technology diffusion by gauging gaps between expected importance and perceived performance rating of the factors. The research presents results of a survey comprising 69 beef organisations from Australia and Singapore. The research identifies critical gaps using two methods of analysis; validity analysis and performance gap analysis. Each method comprises two types of tests. The WarpPLS software is used to perform the validity analysis. Results indicate gaps in level of responsiveness. The research concludes that the success of cross-border collaboration between organisations in both Australia and Singapore can be better achieved through the establishment of information exchange relationships, rather than through the use of technology alone, and by ensuring compatibility between business partners.

Authors: Jiang Jiahong
Published: November 2014

Idioms, an indispensable part of English vocabulary acquisition, play an important role in second language learning. Mobile learning has broken through the constraints of time, space in learning. The present study explored the effectiveness of English idiom instructing and learning based on one form of mobile learning—SMS (Short Message Service). Compared with context-based approach and self-study approach, SMS-based approach was more effective in teaching English idioms for non-English majors in China. The findings of the study showed that students who regularly received short mini-lessons of English idioms via SMS on their mobile phones were more interested in learning and gained more in acquiring English idioms than their peers on pamphlets or context.

E-health is a rising star that marks the collaboration of medical science and information technology, a ray of hope promising a glorious future of health and prosperity, an easy solution to rely on when in need of medical assistance. But the question arises is E-health an absolute spotless option? In this paper we question the integrity with which e-health is being practised, is the code of ethics being diligently followed? And if not then is ethical e-health entirely impossible? It is of utmost importance to encourage the motivational thinkers who have taken the initiative to provide a better and quicker solution to all health problems by integrating health services and information technology. To do so it becomes necessary to remove the barriers in the way of ethical E-health.
Principles of Information Accountability
Authors: Gajanayake Randike , Sahama Tony , Iannella Renato
Published: November 2014

Information accountability is seen as a mode of usage control on the Web. Due to its many dimensions, information accountability has been expressed in various ways by computer scientists to address security and privacy in recent times. Information accountability is focused on how users participate in a system and the underlying policies that govern the participation. Healthcare is a domain in which the principles of information accountability can be utilised well. Modern health information systems are Internet based and the discipline is called eHealth. In this paper, the authors identify and discuss the goals of accountability systems and present the principles of information accountability. They characterise those principles in eHealth and discuss them contextually. They identify the current impediments to eHealth in terms of information privacy issues of eHealth consumers together with information usage requirements of healthcare providers and show how information accountability can be used in a healthcare context to address these needs. The challenges of implementing information accountability in eHealth are also discussed in terms of our efforts thus far.
The Use of the Data Transformation Techniques in Estimating the Shape Parameter of the Weibull Distribution for the Wind Speed
Authors: Kantar Yeliz Mert , Arik Ibrahim
Published: November 2014

In recent years, the Weibull distribution has been commonly used and recommended to model the wind speed. Therefore, many estimators have been proposed to find the best method to estimate the parameters of the Weibull distribution. Particularly, the estimator based on regression procedures with the Weibull probability plot are often used because of its computational simplicity and graphical presentation. However, when the procedure is applied, in many cases heteroscedasticity or non-normality of the error terms may be encountered. One way to handle this problem is using transformation techniques. In this study, the regression estimation based on data transformation is considered to estimate the parameters of the Weibull distribution. The simulation results show that the considered estimator based on the data transformation for the shape parameter of the Weibull distribution provides better performance than least squares estimator in terms of bias and mean square errors for the most of the considered cases.

Gender Differences in Advanced Mobile Services Acceptance
Authors: Guirao Alicia Rodriguez , Nicolas Carolina Lopez , Bouwman Harry
Published: November 2014

By stating that the antecedents of customers´ intentions to use mobile services should be studied across service categories and gender differences, the purpose of this article is to investigate the validity and differential predictive power of a model that explain acceptance of several mobile services across male and female customers. This study contributes to the emerging but limited body of research on consumer adoption of advanced mobile services by addressing several critical issues. First, the present paper focuses on two mobile services, namely m-location and m-social media, as they are considered as the new age of advanced mobile services. Furthermore, we include gender as a moderator variable. A theoretical model is proposed and tested in a sample of 429 Dutch consumers. Results from structural modeling equations show that the factors explaining the acceptance of m-location and m-social media services differ. Second, gender moderating effect has been found significant as gender differences exist in the strength of various paths. In addition to its theoretical contributions, this research presents important practical contributions. In particular, practitioners can gain valuable insights into the driving forces of mobile services.

Authors: Ruiz-Mafé Carla , Sanz-Blas Silvia , Martí-Parreño José
Published: November 2014

Social Networking Sites (SNS) are gaining momentum as powerful tools of marketing communications. Mobile phones are becoming one of the most popular devices for accessing Social Networking Sites. In Spain, 44% of Social Networking Sites users access these sites on a daily basis while 79% of them access these sites on a weekly basis. Furthermore, it is notable that over 70% of Social Networking Sites users talk about and recommend commercial brands. This justifies the interest of the study of Social Networking Sites users from a marketing perspective. The aim of this research is to assess the influence of consumers` personal factors (attitude, innovativeness, and gender) and individual-media relationships (media affinity and individual-media dependency) on mobile SNSs usage behaviour. Managerial implications improving marketers´ advertising effectiveness are also provided.
Apology Strategies for Informal Complaints in Service Recovery and CRM Systems
Authors: Kellogg Deborah L. , Cunningham Lawrence F.
Published: November 2014

This paper reports the results of a quasi-experiment designed to identify linkages between customer attributes and apology types in service recovery in informal resolution settings. Understanding these relationships is critical for enabling more effective and dynamic social relationships between the service provider and the customer/client with the use of technology, namely Customer Relationship Management Systems (CRM). The authors find that simple apologies decrease anger, restore distributive and interactional justice, and increase satisfaction. More importantly, the paper suggests that there are significant nuances in apology types and complex relationships between customer types and effective deployment of the apology in informal resolution settings. Further, the analysis suggests that apologies with explanations are more effective among customers with service experience and that apologies with compensation are most effective for all customers. When apologies are used with successive failures there is some evidence that the apology explanations are not equally effective for all customer types. The paper concludes with a discussion of the linkages between apology, service recovery and CRM systems in informal complaint resolution to improve senior level decision making, employee performance in service recovery, and customer satisfaction in for profit and non-profit organizations.

Published: November 2014

This paper compares public relation practices of experts working in public and private sectors of the UAE based firms. It casts light on the challenges that practitioners face in both sectors and the necessary skill set they need to excel in their field. Qualitative research techniques were used to get insights into the research problem. Qualitative questionnaires and in depth interviews with the target respondents were conducted. Questionnaires were filled by government institutions, public sector insurance companies, schools, private banks, and other organizations. In depth face to face interviews and qualitative questionnaire were used in this study. Out of 60 questionnaires, 30 were distributed and collected face to face in 15 different workplaces in the public sector and 30 were distributed in 12 workplaces in the private sector. The research concluded that the PR sector is well developed in private firms who cater to their publics at an advanced level using the tools and devices necessary for physical and virtual world practice. When it comes to the public sector, PR departments and PR practitioners were not very aware of the contemporary PR concept, and they need better qualifications to improve their PR practices.

Authors: Gupta Sumeet , Goh Mark , De-Souza Robert , Meng Fanwen , Garg Miti
Published: November 2014

Increasing globalization of the supply chains is making them increasingly vulnerable to various supply chain risks. Effective management of these risks is essential to prevent minor as well as major risks that may occur in day-to-day operations of the firm. In this paper an attempt is made to bring out a schema for analyzing supply chain risks faced by the firm and develop a risk management action framework that would serve as a guide for practitioners to identify the level at which their firms are operating and the strategies they need to employ to combat or prevent supply chain risks. The data is collected by means of an online as well as an event survey from logistics managers of various supply chain firms. Indeed Singaporean firms need to properly document these supply chain risks. Moreover, there are gaps in specific areas where Singaporean firms can improve themselves and thus become globally effective corporations.

A Hybrid Methodology of ANN-NSGA-II for Optimization of the Process Parameters of Slotted-Electrical Discharge Abrasive Grinding Process
Authors: Yadav Ravindra Nath , Yadava Vinod
Published: November 2014

Slotted-Electrical Discharge Abrasive Grinding (S-EDAG) is a new innovative hybrid machining process, which is developed by comprising the Electrical Discharge Grinding (EDG) and Abrasive Grinding (AG) where both the processes occur alternatively. The selection of the suitable combination of process parameters is much difficult due to non-linear relation between input and output. The aim of this study is to apply a hybrid approach of Artificial Neural Network (ANN) and Non-Dominated Sorting Genetic Algorithm (NSGA-II) to optimize the process parameters of S-EDAG process during machining of Al/SiC/B4C composite. ANN architecture with back propagation algorithm has been used for modeling, which is trained and tested with experimental data. The experimental data have been collected after exhaustive experimentation considering the effect of current, pulse duration, pulse interval, wheel RPM and abrasive grit number on material removal rate (MRR) and average surface roughness (Ra). The developed ANN model has been coupled with NSGA-II to generate the population and evaluate the objective functions during optimization. The results have been shown that hybrid approach of ANN-NSGA-II provides set of optimal solution that helps to manufacturer to select the appropriate combination of input parameters and reduce the product manufacturing cost.
Finite Element Based Modeling of Surface Roughness in Micro Electro-Discharge Machining Process
Authors: Suryavanshi Ajay , Yadava Vinod , Narayan Audhesh
Published: November 2014

The development of an accurate model for the prediction of surface roughness is still a key issue for Micro Electro-Discharge Machining (micro-EDM) due to its complex nature. In this paper, a Finite Element Method (FEM) based thermal model is developed to estimate the surface roughness based on the geometry of crater produced during micro-EDM process. The crater geometry is obtained using the temperature field in the workpiece. More real considerations such as Gaussian heat flux distribution, temperature dependent material properties, phase change phenomena and overlapping craters are taken for development of this model. Using the present model, parametric simulations have been carried out to analyze the effect of process parameters such as discharge current, energy partition, breakdown voltage, pulse-on time and duty factor on surface roughness produced on the workpiece. The surface roughness values for AISI 4140 and Ti-6Al-4V workpieces obtained from the present developed model agree reasonably well with the experimental results under the same operating conditions, thus showing the potential usefulness of the proposed approach.
Algorithms and Methods Inspired from Nature for Solving Supply Chain and Logistics Optimization Problems
Authors: Dounias Georgios , Vassiliadis Vassilios
Published: November 2014

The current work surveys 245 papers and research reports related to algorithms and methods inspired from nature for solving supply chain and logistics optimization problems. Nature Inspired Intelligence (NII) is a challenging new subfield of artificial intelligence (AI) particularly capable of dealing with complex optimization problems. Related approaches are used either as stand-alone algorithms, or as hybrid schemes i.e. in combination to other AI techniques. Ant Colony Optimization (ACO), Particle Swarm Optimization, Artificial Bee Colonies, Artificial Immune Systems and DNA Computing are some of the most popular approaches belonging to nature inspired intelligence. On the other hand, supply chain management represents an interesting domain of OR applications, including a variety of hard optimization problems such as vehicle routing (VRP), travelling salesman (TSP), team orienteering, inventory, knapsack, supply network problems, etc. Nature inspired intelligent algorithms prove capable of identifying near optimal solutions for instances of those problems with high degree of complexity in a reasonable amount of time. Survey findings indicate that NII can cope successfully with almost any kind of supply chain optimization problem and tends to become a standard in related scientific literature during the last five years.
Information Theoretic XSS Attack Detection in Web Applications
Authors: Shahriar Hossain , North Sarah , Chen Wei-Chuen , Mawangi Edward
Published: November 2014

Cross-Site Scripting (XSS) has been ranked among the top three vulnerabilities over the last few years. XSS vulnerability allows an attacker to inject arbitrary JavaScript code that can be executed in the victim's browser to cause unwanted behaviors and security breaches. Despite the presence of many mitigation approaches, the discovery of XSS is still widespread among today's web applications. As a result, there is a need to improve existing solutions and to develop novel attack detection techniques. This paper proposes a proxy-level XSS attack detection approach based on a popular information-theoretic measure known as Kullback-Leibler Divergence (KLD). Legitimate JavaScript code present in an application should remain similar or very close to the JavaScript code present in a rendered web page. A deviation between the two can be an indication of an XSS attack. This paper applies a back-off smoothing technique to effectively detect the presence of malicious JavaScript code in response pages. The proposed approach has been applied for a number of open-source PHP web applications containing XSS vulnerabilities. The initial results show that the approach can effectively detect XSS attacks and suffer from low false positive rate through proper choice of threshold values of KLD. Further, the performance overhead has been found to be negligible.
Design Churn as Predictor of Vulnerabilities?
Authors: Hovsepyan Aram , Scandariato Riccardo , Steff Maximilian , Joosen Wouter
Published: November 2014

This paper evaluates a metric suite to predict vulnerable Java classes based on how much the design of an application has changed over time. It refers to this concept as design churn in analogy with code churn. Based on a validation on 10 Android applications, it shows that several design churn metrics are in fact significantly associated with vulnerabilities. When used to build a prediction model, the metrics yield an average precision of 0.71 and an average recall of 0.27.
Secure Software Development Assimilation
Authors: Song Mingqiu , Chen Donghao , Mkoba Elizabeth Sylvester
Published: November 2014

Drawing upon institutional theory, this article develops an extended model to test and verify the effects of external institutional pressures on Secure Software Development (SSD) assimilation and the roles of internal critical factors. The empirical results are based on 86 survey data from respondents of related organizations in United Kingdom, Hong Kong, and Mainland China who have related project experience about SSD. Results from partial least squares (PLS) analysis suggest that both mimetic and coercive pressures have indirect effects on SSD assimilation with the distal mediation of top management. Normative pressures positively affect SSD assimilation with the full mediation of secure software champion. Results also suggest that secure software champion plays another partial mediation between top management participation and SSD assimilation. This paper highlights the important role of secure software champion for its dually mediating effects on both external and internal forces during SSD assimilation process.
A Taiwanese Empirical Study of Online Group Buying from the Perspectives of Organizational Culture and Transformational Leadership
Authors: Yang Mu-Li
Published: November 2014

This study examines online group-buying from the perspectives of organizational culture and transformational leadership. A convenience sampling of 400 online group-buying individuals living in Taiwan was conducted in 2011, and this yielded 300 effective questionnaires, giving a return rate of 75%. ANOVA analyses and canonical correlation were used to examine the participants' perceptions of organizational culture and the leadership of online group-buying initiators, and the relationship between these leadership behaviors and the organizational culture in their workplaces. The main findings of this study are as follows: (1) online group-buying activities occur most often in organizations with a “supportive” culture; (2) “idealized influence” is the most influential leadership behavior with regard to the perceptions of group-buying members towards group-buying initiators; and (3) the better initiators are able to perform with regard to “individual consideration” and “idealized influence,” the greater the positive effects on online group-buying activities in the organizations with “supportive” and “innovative” organizational cultures.

Published: November 2014

Hughes and Stovin first reported a syndrome consisting of multiple pulmonary artery aneurysms and venous thrombosis in 1959. Here, we encountered a 42-year old woman who had hemoptysis revealing a Hughes- Stovin syndrome. Helical computed tomography showed multiple pulmonary artery aneurysms with pulmonary thromboembolism. The patient was treated with steroid therapy, cyclophosphamide and anticoagulation with a good response.
Noteridae, Dytiscidae (Coleoptera) du Gabon (8ème partie). Monts de Cristal
Authors: Bilardo Armando , Rocchi Saverio
Published: November 2014

Noteridae, Dytiscidae (Coleoptera) from Gabon (eighth part). Monts de Cristal. This work concerns the Coleoptera Hydradephaga collected in eight localities of Monts de Cristal (Republic of Gabon) included locality of Tchimbélé into the National Park of Monts de Cristal in years 2006 - 2010; altogether 76 species are listed (3 Noteridae and 73 Dytiscidae) of which 51 species found in the Park. The authors describe two new species: Copelatus angouei (group consors, sensu Guignot, 1961, distinguishable from other species of group by small size, the robust conformation, the upper side clearly microreticulate covered by fine and thick punctuation which give it an opaque look and by characteristic penis), Copelatus nguemai (group irinus, subgroup assimilis, sensu Guignot, 1961, related to assimilis Régimbart, 1895, distinguishable by longer spine of metatibia clearly curved at third apical in both sexes and by characteristic penis) and one new subspecies: Copelatus lasckonyi tchimbelensis (group irinus, subgroup irinus, sensu Guignot, 1961, characterized by very small size, by narrowed profile of the body from shoulders in some specimens and by the upper side finely microreticulate, penis, very characteristic, is identical to typical form). The examination of two sintypes of Copelatus variegatus Régimbart, 1895 (group erichsoni, subgroup atrosulcatus, sensu Guignot, 1961) of Muséum Nationale d’Histoire Naturelle of Paris and of specimens of related species of the Museums of Tervuren and Bruxelles permitted the determination of the specimens of C. variegatus collected during research and the redescription of the species known till now by the two sintypes (here respectively designate lectotype and paralectotype); meanwhile a new species has been identified: Copelatus mendax, belonging to same group and subgroup of C. variegatus, misidentified with veritable C. variegatus. Some taxa of aquatic macroinvertebrates (Hexapoda, Malacostraca, Clitellata et Mollusca) in the zone collected and determined by a Researcher of IRAF (CENAREST, Gabon), Blaise Mboye Rollinat, who had participated in mission 2010, are furnished. Observations on some of the collected species and some ecological data of the biocenoses that populate the zone and some considerations on aquatic Coleoptera habitats are presented. The name of the species Copelatus efoutensis Bilardo & Rocchi, 1995 is amended in efotensis. Hydrovatus senegalensis Régimbart, 1895 and Uvarus barombicus Bilardo, 1982 are signalled for the first time of Gabon.
Retropluma craverii (Crema, 1895) (Crustacea, Decapoda, Brachyura, Retroplumidae) from the Pliocene of Reggio Emilia (N Italy)
Authors: De Angeli Antonio , Garassino Alessandro , Pasini Giovanni
Published: November 2014

We report two specimens of retroplumid crabs from the Pliocene of Reggio Emilia (N Italy), ascribed to Retropluma craverii (Crema, 1895), known to date only from the Pliocene of Piemonte. The re-examination of the holotype together with the good state of preservation of the studied specimens has allowed a re-description of this species, poorly known to date.
A new species of ghost shrimp (Decapoda, Thalassinidea, Callianassidae) from the Late Cretaceous (Cenomanian) of Agadir (W Morocco)
Authors: Garassino Alessandro , De Angeli Antonio , Pasini Giovanni
Published: November 2014

We report Neocallichirus agadirensis n. sp. (Decapoda, Thalassinidea, Callianassidae) from the Late Cretaceous (Cenomanian) of Agadir (W Morocco). This species has been described based upon four specimens that preserve ischium, merus, carpus, propodus, and dactylus of the great cheliped. The new species represents the first report of Neocallichirus in Africa and the oldest species known to date belonging to this genus.
