Authors: Battistuzzo Flávio Jorge , Piscopo Marcos 
Published: September 2015

A gestão de projetos é um processo fundamental na implementação de estratégias. Diferentes organizações se utilizam dos seus conceitos e ferramentas para a implementação destas estratégias, na obtenção e manutenção de vantagens competitivas. A importância da gestão de projetos na execução adequada das estratégias tem recebido a atenção de vários acadêmicos, apresentando uma série de especificidades que tornam sua aplicação mais difícil de gerenciar, como aspectos culturais e deficiências internacionais. Considerando que o sucesso das estratégias e das organizações está relacionado ao sucesso dos projetos, compreender os projetos globais implica no entendimento de como as teorias de administração podem ser aplicadas à gestão de projetos para tornar as organizações mais bem-sucedidas. Este estudo bibliométrico tem como objetivo identificar as tendências atuais relacionadas à literatura de projetos globais e avaliar o estado da arte destas publicações. Nossa conclusão indica um foco em teoria institucional, processos de análise / decisão de riscos e marketing de projetos. Acreditamos que nosso estudo possa incentivas e dar suporte a outros acadêmicos a pesquisar os agrupamentos existentes e avaliar como as teorias organizacionais podem ser aplicadas à gestão de projetos globais.
Efficiency of Steam-Over-Solvent-Injection-in-Fractured-Reservoirs (SOS-FR) Method Considering Oil Recovery and Solvent Retrieval: Core-Scale Experimentation
Authors: Mohammed M. Almojtaba , Babadagli Tayfun 
Published: September 2015

Summary
Sole injection of steam or solvent into heterogeneous reservoirs usually yields an inefficient recovery performance. The steam-over-solvent-injection-in-fractured-reservoirs (SOS-FR) method was suggested as a solution to improve the efficiency of heavy-oil/bitumen recovery from fractured carbonates and oil-sands reservoirs after cold production (Al-Bahlani and Babadagli 2008). The method consists of three phases: Phase 1, where steam is injected at low temperatures to heat the matrix and condition the oil for subsequent solvent injection; Phase 2, when solvent-injection dilutes matrix oil by diffusion and enhances gravity-drainage recovery rate; and Phase 3, when low-temperature (at approximately the boiling point of solvent) steam injection retrieves the solvent diffused into matrix.
Previous research was focused on the effectiveness of Phases 1 and 2 of the method (Al-Bahlani and Babadagli 2009a, b), and positive responses were reported at the field scale (Al-Bahlani and Babadagli 2010) with high ultimate recoveries. The efficiency of this process, however, is determined purely by the amount of solvent retrieved at the end of the process. This paper, therefore, focuses on Phase 3, which is performed mainly for solvent retrieval (additional oil is also produced during this phase). Twenty-two static core experiments were performed on water- and oil-wet sandstone and limestone. After saturating the rock samples with different heavy oils, they were immersed into different liquid solvents--hexane, heptane, decane, and diluent oil. Diluent oil used in this study is a distillate that was obtained from a heavy-oil-upgrading unit in Canada. Once the ultimate recovery was achieved by diffusion and gravity drainage (Phase 2), the samples were exposed to different temperatures of hot water (Phase 3) and the amount of solvent retrieved was measured through volumetric and weight measurements and refractometer readings. The retrieval of solvent diffused into matrix was caused mainly by two reasons: (1) evaporation of solvent at elevated temperature and (2) imbibition of hot water into rock (if oil-wet samples become more water-wet during Phase 2).
The amount of solvent retrieved through these processes was determined, and the efficiencies were analyzed for different parameters, including rock wettability, oil viscosity, solvent type, solvent-soaking period, rock type, boundary conditions, different combinations of steam/solvent cycle, and temperature applied.
Tight Cardium Multistage-Fractured Horizontal-Oil-Well-Performance Study Focusing on the Effectiveness of Various Fracture-Fluid Systems
Authors: Reynolds Murray , Moscoso Krefthelle , Buendia Juliana , Gallup Michael 
Published: September 2015

Summary
In recent years, the tight Cardium sandstones of west central Alberta have observed significant new development with the application of multistage-fractured horizontal wells (MFHWs). This case study reviews the completion costs, economics, and production performance of 148 horizontal oil wells completed in the Pembina field halo areas (west and east), central Pembina, Willesden Green, and Garrington fields.
Production analysis was performed on all wells using the Duong decline-curve-analysis technique. This technique has been used successfully on tight multistage-fractured wells in other areas, and has proved successful at predicting long-term well performance and recoveries. Wells were chosen for comparison that were in the same geological and pressure regions, had a minimum of 2 years of production information, and were stimulated with various fracture-fluid systems.
In one of the analyzed areas, a definite trend was identified; it was found that wells drilled in a certain orientation performed better than wells drilled with other orientations.
Completions and hydraulic-fracturing costs were gathered from public sources in order to understand the cost differences between areas and types of fracture-fluid systems. Using decline curves and cost information, full-cycle economics were run on the ’average’ well for each area in order to determine the net present value (NPV) of each area.
This case study shows there is value in optimizing fracture designs through look-back studies, and there is a need to focus on more-effective fracture-treatment designs in unconventional oil development. The overall results of the study showed: (1) the choice of fracture-fluid system is a key component in optimizing economics in the Cardium halo areas; and (2) the optimum fluid system varies in different areas of the Cardium.
Benchmarking the Supercomputer Trace 7/200
Authors: O'Donnell J. J. , Campbell C. L. , Chase C. A. , Woo P. T. 
Published: September 2015

Abstract
The supercomputer Multi flow TRACE 7/200 was benchmarked with a compositional simulation model. For comparison, the model was also run on the CRAY X-MP/12, the CONVEX C-l XP, and the ALLIANT FX/8-8. The performance of the computer was judged in terms of CPU time and main memory requirements.
The Multiflow system uses the very long instruction word (VLIW) architecture. The instruction word can be as wide as 1,024 bits. It is packed with up to 28 primitive machine operations, which are executed in overlapped fashion. Thus, many different operations such as load, store, add, multiply, etc. may be executed simultaneously in one clock cycle.
The entrance level Multi flow system is the TRACE 7/200. It has a cycle time of 130 ns. Up to 7 operations may be executed on the 7/200 per instruction, resulting in 53 MIPs and 60 MFLOPs.
The object code for the Multi flow system is generated by the trace-scheduling compacting compiler. In addition to generating the compacted instructions for the VLIW, the computer predicts branch paths and prepares compensation codes to guarantee correct branching. The amount of compensation codes must be small in order not to degrade computing efficiency.
The reservoir model was an expanded version of the gas cycling model in the Third SPE Comparative Solution Project. It was derived by repeating the SPE model twice in the × direction and 4 times in the y direction. The dimensions of the new grid were thus 18 × 36 × 4. There were 8 injection wells and 8 production wells in the new grid.
The MULTIFLOOD simulator of Todd, Dietrich & Chase, Inc. was used to run the numerical model. The simulator is 3-dimensional, 3-phase, and compositional. It solves the system of partial differential equations by the finite difference technique and Newton-Rafson iteration. The system of linear equations is solved by Gaussian elimination with alternate diagonal ordering.
The scalar version of MULTIFLOOD was used in benchmarking. A ground rule was established that no changes were to be made to optimize the source code for each computer. However, the object code could be optimized by involving the appropriate compiler options or directives for vectorization on the CRAY and the CONVEX or for parallelization on the ALLIANT. On the TRACE, a fine tuning tool was used to assist the compiler in unrolling and in automatic inlining of the object code.
In evaluating the benchmark results, the simulator calculations are grouped into 4 categories. They are: physical properties evaluation, formation of finite difference coefficients, solution of linear equations, and miscellaneous calculations.
Electrical Conductivity Breakthrough Experiment and Immobile Water Estimation in Organic Substrates: Is R = 1 a Realistic Assumption?
Authors: Caron Jean , Létourneau Guillaume , Fortin Josée 
Published: September 2015

Core Ideas
Breakthrough of NaCl in peat shows that R may differ from 1.
Immobile water in peat is difficult to estimate because of NaCl sorption.
Solute sorption in peat varies because of uncoiling of organic components.
Measuring electrical conductivity (EC) in outflow breakthrough curves (BTCs) is an approach commonly used to define transport parameters because it is rapid, inexpensive, and reliable. Earlier work has raised questions regarding the assumption that the retardation factor may be set at R = 1 when using EC as a tracer in organic soils. This study investigates the breakthrough of a NaCl tracer in a peat–sawdust mixture leached with distilled water. The results show that in such system, R may significantly differ from 1 because of sorption of Na+ and Cl− by peat with the R value estimated by batch experiments to reach 1.9 for Na+ and 1.5 for Cl−. The sorption properties may vary during solute transport because of uncoiling of humic and fulvic components with decreasing ionic strength of the solution.
Delegated integrity check for hierarchical cloud data
Authors: Shen Shiuan-Tzuo , Tzeng Wen-Guey 
Published: September 2015

Abstract In cloud storage, a data owner can store his data in a cloud and authorize some users to access his data. Since the data are outsourced to the cloud, the authorized users should check the data to assure integrity. The data owner does not allow unauthorized users to check integrity of his data. There are many private and public integrity check schemes. Nevertheless, this paper concerns the verification key spread problem. Delegated integrity check deals with the verification key spread problem and provides effective management of verifiers. A data owner can delegate a verifier to check his data and revoke the right of the verifier later. The verifier cannot re-delegate his integrity check capability to someone else. Delegated integrity check guarantees that only the delegated verifier can check integrity of data. This paper provides the model of delegated integrity check, an application scenario of personal health records, and two delegated integrity check schemes for hierarchical cloud data. The first scheme allows a verifier to check data possession of a storage server. The second scheme allows a verifier to check data retrievability from a storage server. The schemes achieve proof unforgeability, proof indistinguishability and delegation key unforgeability in the random oracle model.
CookiExt: Patching the browser against session hijacking attacks
Authors: Bugliesi Michele , Calzavara Stefano , Focardi Riccardo , Khan Wilayat 
Published: September 2015

Abstract Session cookies constitute one of the main attack targets against client authentication on the Web. To counter these attacks, modern web browsers implement native cookie protection mechanisms based on the HttpOnly and Secure flags. While there is a general understanding about the effectiveness of these defenses, no formal result has so far been proved about the security guarantees they convey. With the present paper we provide the first such result, by presenting a mechanized proof of noninterference assessing the robustness of the HttpOnly and Secure cookie flags against both web and network attackers with the ability to perform arbitrary XSS code injection. We then develop CookiExt , a browser extension that provides client-side protection against session hijacking, based on appropriate flagging of session cookies and automatic redirection over HTTPS for HTTP requests carrying these cookies. Our solution improves over existing client-side defenses by combining protection against both web and network attacks, while at the same time being designed so as to minimise its effects on the user’s browsing experience. Finally, we report on the experiments we carried out to practically evaluate the effectiveness of our approach.

SummaryIntroduction: This article is part of the Focus Theme of Methods of Information in Medicine on “Methodologies, Models and Algorithms for Patients Rehabilitation”. Background: Rheumatoid arthritis (RA) is a progressive inflammatory disease that causes damage to multiple joints, decline in functional status, and premature mortality. Thus, effective and frequent objective assessments are necessary. Then, we developed a self-assessment system for RA patients based on a smartphone application. Objective: The purpose of this study was to investigate the feasibility of a self-assessment system for RA patients using a smart-phone application. Methods: We measured daily disease activity in nine RA patients who used the smart-phone application for a period of three months. A disease activity score (DAS28) predictive model was used and feedback comments relating to disease activity were shown to patients via the smartphone application each day. To assess participants’ RA disease activity, the DAS28 based on the C-reactive protein level was measured by a rheumatologist during monthly clinical visits. Results: The disease activity measured by the application correlated well with the patients’ actual disease activity during the 3-month period, as assessed by clinical examination. Furthermore, most participants gave favourable responses to a questionnaire administered at the end of the 3-month period containing questions relating to the ease of use and usefulness of the system. Conclusions: The results of this feasibility study indicated that the DAS28 predictive model can longitudinally predict DAS28 and may be an acceptable and useful tool for assessment of RA disease activity for both patients and healthcare providers.
Cognitive Maps to Visualise Clinical Cases in Handovers
Authors: Flemming D. , Przysucha M. , Hübner U. 
Published: September 2015

SummaryBackground: Clinical handovers at changes of shifts are typical scenarios of time restricted and information intensive communication, which are highly cognitively demanding. The currently available applications supporting handovers typically present complex information in a textual checklist-like manner. This presentation style has been criticised for not meeting the specific user requirements.Objectives: We, therefore, aimed at developing a concept for visualising the overview of a clinical case that serves as an alternative way to checklist-like presentations in clinical handovers. We also aimed at implementing this concept in a handoverEHR in order to support the pre-handover phase, the actual handover, and the post-handover phase as well as at evaluating its usability and attractiveness.Results: We developed and implemented a concept that draws on Tolman’s pioneering work on cognitive maps that we designed in accordance with Gestalt principles. These maps provide a pictorial overview of a clinical case. The application to build, manipulate, and store the cognitive maps was integrated into an openEHR based handover record that extends conventional records with handover specific information. Usability (n = 28) and attractiveness (n = 26) testing with experienced clinicians resulted in good ratings for suitability for the task as well as for attractiveness and pragmatism.Conclusion: We propose cognitive maps to represent and visualise the clinical case in situations where there is limited time to present complex information.
Comment devient-on un « gars du groupe » quand on est une fille ?
Authors: Ginhoux Bérangère 
Published: September 2015

Le monde du football et celui des supporters ultras restent très majoritairement dominés par les hommes. Les femmes, engagées dans ces mondes, sont régulièrement déconsidérées et leurs pratiques disqualifiées. Cet article s’intéresse spécifiquement à l’engagement des membres féminins de groupes de supporters ultras. Comment arrivent-elles à mener à bien leur carrière dans un contexte hostile à leur investissement ? Quelles sont les combines auxquelles elles ont recours afin d’être considérées comme des « gars du groupe » ? Cet article repose sur des données issues d’un travail d’enquête ethnographique, mené par observation participante au sein de groupes ultras et par entretiens semi-directifs avec des supportrices et des supporters ultras en Europe.
Apprendre du stigmate par l’expérimentation
Authors: Bailleul Michaël 
Published: September 2015

Cet article montre comment et en quoi l’expérimentation du stigmate d’être un jeune issu d’un « quartier » peut devenir une source de savoirs, voire constituer un tuteur d’apprentissage positif. Il fait l’hypothèse que certains « jeunes des quartiers » tout en vivant au quotidien avec le stigmate dépassent le sentiment de soumission et parviennent à construire de nouvelles aptitudes qui leur sont profitables. Il montre que la connaissance des origines du stigmate peut être source de contrebalancement positif et être utilisé par les jeunes dans le cadre de stratégies d’interaction élaborées. Ce mécanisme d’émancipation qui émerge partiellement dans cette enquête témoigne d’une certaine capacité à s’affranchir.
Inclusion scolaire et action publique, entre contradictions et inachèvement
Authors: Mazereau Philippe 
Published: September 2015

Cet article traite de la place et de la fonction de deux politiques publiques dans la réduction des inégalités sociales. L’apparition d’une configuration qui combine exclusion-mixité sociale-inclusion en posant une question sociale transversale proposerait un nouvel horizon mobilisateur. L’auteur développe ce point de vue à partir de deux histoires parallèles : celle du développement, à partir de 1975, d’une politique publique sociale envers les personnes handicapées, et celle de l’école républicaine, du système éducatif, lequel tient une place éminente dans la production de la cohésion nationale. L’article rend compte des principales articulations de ce qui s’apparente, selon l’auteur, à un chassé-croisé entre les réorientations législatives de ces deux politiques publiques, entre politique scolaire et du handicap.
Using Simulation Pedagogy in the Formation of Family-Focused Generalist Nurses
Authors: Eggenberger Sandra K. , Krumwiede Norma K. , Young Patricia K. 
Published: September 2015

Background:
Nursing practice with families is essential because a family member’s illness affects the family and, reciprocally, the family influences health outcomes. Yet, nurses often report a lack of confidence in their ability to meet the needs of families, whereas family members often describe troubling experiences with nurses. These challenges may have beginning roots in nursing education. This article explores the use of simulation in the formation of family-focused generalist nurses.

Method:
Simulation pedagogy was used to guide students in developing an understanding of the importance of family nursing care, gaining confidence in family practices, and developing family competencies.

Results:
Innovative simulation learning experiences in an undergraduate nursing curriculum helped students to learn how to develop nurse–family relationships and gain humanistic skills of family nursing practices. Students and faculty reported that simulation guides students to achieve meaningful outcomes.

Conclusion:

In this curriculum, faculty consistently directs attention to the family in simulation learning experiences, and students value this pedagogy. [

Field Evaluation of Automated Vision Screening Instruments: Impact of Referral Criteria Choice on Screening Outcome
Authors: Silverstein Evan , Donahue Sean P. 
Published: September 2015

Purpose:
Automated vision screeners can identify children with amblyopia risk factors. Two screening instruments having different referral criteria were evaluated in a community setting: SPOT (Pediavision, Lake Mary, FL) (sensitive manufacturer's referral criteria) and plusoptiX S08 (Plusoptix GmbH, Nuremberg, Germany) (specific modified Arthur referral criteria).

Methods:
All children were screened by SPOT, and referred children were then screened using plusoptiX. Referred children received a gold standard examination to determine whether amblyopia risk factors were present.

Results:
A total of 2,801 treatment-naïve children were screened using SPOT. Of these, 307 (11.0%) were referred by SPOT and subsequently screened by plusoptiX; 100 received a gold standard examination. Amblyopia risk factors were present in 43% (43 of 100) referred by SPOT compared to 72.7% (32 of 44) for plusoptiX. Eleven of 56 referred by SPOT had amblyopia risk factors that would have been missed by plusoptiX, including three with mild amblyopia.

Conclusions:
PlusoptiX with modified Arthur referral criteria can be a highly specific screening device detecting amblyopia risk factors without missing children with moderate/severe amblyopia.

TLR and RLR Signaling Are Reprogrammed in Opposite Directions after Detection of Viral Infection

Abstract
Innate immune recognition of RNA is key for the initiation of immunity in response to viral infection. Although the factors controlling the detection of viral RNA by innate immune receptors in host cells are increasingly well understood, little is known about the dynamic changes in signaling after the initial triggering of these receptors. In this study, we report that preconditioning with the synthetic dsRNA polyinosinic-polycytidylic acid [poly(I:C)], a mimetic of viral RNA, rapidly reprograms murine APCs by simultaneously augmenting sensitivity of endosomal TLRs and inhibiting activation of RIG-I–like receptors (RLRs) in an IFN-β–dependent manner. These changes in receptor sensitivity were also seen in vivo after treatment of mice with poly(I:C). Mechanistically, the increased sensitivity of the TLR pathway was associated with elevated MAPK and NF-κB activity. The RLR response was inhibited downstream of TANK-binding kinase-1, resulting in decreased IFN regulatory factor 3 phosphorylation. Reprogramming of pattern-recognition receptor signaling also occurred after viral infection, because infection of host cells with Sendai virus or their exposure to supernatant from virus-infected cells induced the same changes in TLR and RLR sensitivity as poly(I:C). Thus, innate recognition of viral infection critically modifies responses to pattern-recognition receptor stimulation. These dynamic adaptations to infection may reinforce antiviral immunity and at the same time serve to limit pathological inflammation.
