Agir par l’hébergement avec des usagers de drogues. Avancées, paradoxes et impasses des espaces intermédiaires
Authors: Maillard Isabelle
Published: October 2016

Cet article se propose d’analyser une expérience d’hébergement expérimental avec des personnes en situation de grande précarité vivant dans la rue et consommant du crack. L’étude du contexte et de la dynamique engagée fait apparaître une figure récurrente de l’action publique : l’ouverture, dans les phases de crise du domaine sanitaire et social, de possibilités d’expérimentation dérogeant aux conditions ordinaires d’action des institutions. Ici un espace conçu comme un lieu de transition où la réduction des vulnérabilités passe par le développement du pouvoir d’action des personnes, les compétences relationnelles, les valeurs et les logiques d’action des intervenants en première ligne se trouvent revisitées. Les contradictions et dilemmes liés à l’état des institutions et aux difficultés propres au travail avec des personnes cumulant des vulnérabilités placent ce type d’expériences dans une fragilité propre sur le plan de la production des changements escomptés.
Parcours de demandeurs d’asile : diffraction spatiale et traumatisme
Authors: Baligand Pascale
Published: October 2016

Cet article explore les liens entre espace et subjectivité à partir de plusieurs parcours de demandeurs d’asile. Ces parcours peuvent être considérés comme relevant de la vulnérabilité car ils sont marqués par la concomitance d’une désorientation psychique et d’un morcellement des espaces. Cette vulnérabilité façonne les rapports à l’espace de la ville, suivant trois temps successifs qui la mettent en jeu différemment : celui de la montée des périls dans le pays d’origine, celui de la migration, et celui de l’arrivée dans le pays d’accueil et de l’attente de l’attribution du statut de réfugié.
La vulnérabilité des villes au terrorisme. Les dilemmes de l’action publique
Authors: Baudouï Rémi
Published: October 2016

After the attacks of the 09/ 11 European authorities have questioned which role should play cities in the prevention of terrorism. In France, the fight against terrorism is old. It’s responsibility of national authorities, not local authorities. The purpose of this article is to measure the nature of institutional and administrative gap that justify the French cities can’t enter now in the security paradigm. To do this, we adopt the constructivist analysis in political science.
Enfants, adolescents : des pièces maîtresses du puzzle périurbain
Authors: Aragau Claire , Didier-fèvre Catherine , Rougé Lionel
Published: October 2016

This analysis made from a lot of current investigations and surveys on the Grand Paris focuses on the role of the young generation as a major key for the understanding of the new local ties between the young people and their territories. What kind of everydaylife territories could take shape through the different chilhood’s steps, then for the teens ? How do they adapt themselves over their new periurban territories ? At what extent do the local policymakers account the young generation through the public policies as a major element for the local development and to strengthen all the urban territories ?
La construction d’un espace « à nous » : la mobilité spatiale à l’adolescence
Authors: Ramos Elsa , Singly François de
Published: October 2016

À partir d’un corpus d’entretiens auprès d’adolescentes et d’adolescents du centre ville et de banlieues environnantes de Paris et de Lisbonne, cet article analyse la mobilité urbaine et sa signification. Les adolescents insistent surtout sur les «coins » et les «recoins » qui leur permettent de se réfugier pour faire ce qu’ils veulent, pour rire, pour avant tout échapper à la surveillance des adultes. Ils ne sont pas à la conquête du plus grand déplacement possible. Ils cherchent surtout à avoir un petit monde à eux, sans rêver, pour le moment, à de plus grandes étendues urbaines.
Leveraging Data for Student Success: Improving Education Through Data-Driven Decisions
Authors:   RTI International, Knapp Laura , Glennie Elizabeth , Charles Karen
Published: October 2016

People providing services to schools, teachers, and students want to know whether these services are effective. With that knowledge, a project director can expand services that work well and adjust implementation of activities that are not working as expected. When finding that an innovative strategy benefits students, a project director might want to share that information with other service providers who could build upon that strategy. Some organizations that fund programs for students will want a report demonstrating the program’s success.
Determining whether a program is effective requires expertise in data collection, study design, and analysis. Not all project directors have this expertise—they tend to be primarily focused on working with schools, teachers, and students to undertake program activities. Collecting and obtaining student-level data may not be a routine part of the program. This book provides an overview of the process for evaluating a program. It is not a detailed methodological text but focuses on awareness of the process. What do program directors need to know about data and data analysis to plan an evaluation or to communicate with an evaluator? Examples focus on supporting college and career readiness programs. Readers can apply these processes to other studies that include a data collection component.
THE IMPACT OF MASS SEGREGATION AND STAR FORMATION ON THE RATES OF GRAVITATIONAL-WAVE SOURCES FROM EXTREME MASS RATIO INSPIRALS
Authors: Aharon Danor , Perets Hagai B.
Published: October 2016

Compact stellar objects inspiraling into massive black holes (MBHs) in galactic nuclei are some of the most promising gravitational-wave (GWs) sources for next-generation GW detectors. The rates of such extreme mass ratio inspirals (EMRIs) depend on the dynamics and distribution of compact objects (COs) around the MBH. Here, we study the impact of mass-segregation processes on EMRI rates. In particular, we provide the expected mass function (MF) of EMRIs, given an initial MF of stellar black holes (SBHs), and relate it to the mass-dependent detection rate of EMRIs. We then consider the role of star formation (SF) on the distribution of COs and its implication on EMRI rates. We find that the existence of a wide spectrum of SBH masses leads to the overall increase of EMRI rates and to high rates of the EMRIs from the most massive SBHs. However, it also leads to a relative quenching of EMRI rates from lower-mass SBHs, and together produces a steep dependence of the EMRI MF on the highest-mass SBHs. SF history plays a relatively small role in determining the EMRI rates of SBHs, since most of them migrate close to the MBH through mass segregation rather than forming in situ. However, the EMRI rate of neutron stars (NSs) can be significantly increased when they form in situ close to the MBH, as they can inspiral before relaxation processes significantly segregate them outward. A reverse but weaker effect of decreasing the EMRI rates from NSs and white dwarfs occurs when SF proceeds far from the MBH.
The Role of High-resolution Peripheral Quantitative Computed Tomography as a Biomarker for Joint Damage in Inflammatory Arthritis
Authors: Tam Lai-Shan
Published: October 2016

Since 2011, members of the SPECTRA Collaboration (Study grouP for xtrEme-Computed Tomography in Rheumatoid Arthritis) have investigated the validity, reliability, and responsiveness of high-resolution peripheral quantitative computed tomography (HR-pQCT) as a biomarker for joint damage in inflammatory arthritis. Presented in this series of articles are a systematic review of HR-pQCT-related findings to date, a review of selected images of cortical and subchondral trabecular bone of metacarpophalangeal (MCP) joints, results of a consensus process to standardize the definition of erosions and their quantification, as well as an examination of the effect of joint flexion on width and volume assessment of the joint space.
Suicide in Childhood
Authors: Durand Simone C. , McGuinness Teena M.
Published: October 2016

Suicide by children younger than 11 is a sad and tragic occurrence. Indeed, suicidal ideation and behavior has been documented in children as young as ages 3 to 7. The current overview provides a discussion of the frequency of suicide in children and associated predisposing conditions, such as depression and abuse. In response to these tragic events, nursing interventions are also proposed. [

Clinical Simulation in Psychiatric-Mental Health Nursing: Post-Graduation Follow Up
Authors: Lilly Mary LuAnne , Hermanns Melinda , Crawley Bill
Published: October 2016

In psychiatric–mental health, creating an innovative strategy to help students learn content that may not be frequently seen in a clinical setting is challenging. Thus, simulation helps narrow this gap. Using Kirkpatrick and Kirkpatrick's model of evaluation to guide the current study, faculty contacted baccalaureate nursing program graduates who completed a psychiatric–mental health clinical simulation scenario featuring a hanging suicide and wrist cutting suicide attempt scenario in the “Behind the Door” series as part of the clinical component of their undergraduate psychiatric–mental health course. Eleven nurses responded to a survey regarding their post-graduate encounters with these types of clinical situations, and their perception of recall and application of knowledge and skills acquired during the simulation experience to the clinical situation. Nursing graduates' responses are expressed through three major themes: emotional, contextual/behavioral, and assessment outcomes. Data from the survey indicate that nursing graduates perceived the “Behind the Door” simulations as beneficial to nursing practice. This perception is important in evaluating knowledge transfer from a simulation experience as a student into application in nursing practice. [

Primary productivity and phytoplankton dynamics in a subtropical estuary: a multiple timescale approach
Authors: Parizzi Rafael Antonio , Da Costa Machado Eunice , Prestes Dos Santos Tavares Camila , Felício Fernandes Luciano , Garcia De Camargo Mauricio , Laureno Mafra Jr. Luiz
Published: October 2016

Temporal variability of physicochemical parameters and phytoplankton primary productivity, abundance and composition were investigated at Babitonga Bay, southern Brazil, using a hierarchical sampling design on the scales of months, weeks and days during spring 2012 and summer 2013. Only temperature, respiration rates and concentrations of dissolved oxygen and silicate exhibited significant differences in the greatest timescale (seasons: spring; summer). In contrast, most physicochemical parameters, such as salinity and the concentration of nitrogen compounds, varied mainly among weeks and days. This short-scale variability was similarly observed for the microphytoplankton abundance, ranging from 0.04 to 1.7.106 cells L–1 during a bloom of the diatom Skeletonema costatum. Two major phytoplankton assemblages were associated with high primary production rates: > 30 μm centric diatoms such as Cyclotella spp. and Cymatodiscus sp., in spring; and a summer assemblage dominated by smaller, bloom-forming diatoms (S. costatum and Eucampia cornuta). Primary production ranged from 10.5 to 1793 mg C m–2 d–1 and varied significantly between days and months, being associated with the photosynthetic active radiation level and weather conditions on the sampling day. Abundance of specific plankton taxa appeared controlled by trophic interactions, as revealed for the mixotrophic, toxic dinoflagellate Dinophysis acuminata complex and its prey, the ciliate Mesodinium rubrum.
Estimating the selectivity of unpaired trawl data: a case study with a pelagic gear
Authors: Sistiaga Manu , Herrmann Bent , Grimaldo Eduardo , O’Neill Finbarr G.
Published: October 2016

Most selectivity experiments employ either the covered codend or paired gear methods. It is not always possible, however, to use these methods. Owing to operational, biological and/or environmental considerations, there may be no obvious way or it may be inappropriate to pair the test and control data. Hence, it will not be possible to estimate the selectivity of the gear and its uncertainty using standard statistical methods. This study presents a methodology for analysing the selectivity of fishing gears from unpaired test and control data. The uncertainty in the control and test population structures is accounted for by using a double bootstrapping procedure that takes into account both between-haul and within-haul variation. This bootstrapping approach is used to assess the selectivity of two different devices, a 139.5 mm T90 codend and a 135.9 mm codend with 140.9 mm lateral exit windows, in the Barents Sea pelagic cod trawl fishery. The purpose of the experiment was to test and compare the performance of the two devices in pelagic trawl fisheries, where high densities of fish can be encountered. Significant differences were detected between the T90 codend and the codend with the exit windows but only for sizes of cod between 55 and 76 cm.

O objetivo é abordar o debate sobre desenvolvimento suscitado pela política econômica dos governos do Partido dos Trabalhadores (PT), enfocando as visões desenvolvimentista e ambientalista para, em seguida, discorrer sobre a Usina Hidrelétrica de Belo Monte como caso ilustrativo da complexidade dos processos de intervenção estatal visando avanços em infraestrutura por meio de grandes obras, em nome do desenvolvimento. Dessa perspectiva, interessa destacar o resgate do isolamento político de populações inseridas nos modos de vida tradicionais e, além dos ganhos em ativismo político, apontar para ganhos socioeconômicos, simultaneamente à barbárie envolvida na construção de Usina no Rio Xingu, Pará, Brasil.
O futuro da Amazônia: horizonte de expectativa de Arthur Reis (década de 1950)
Authors: Lobato Sidney
Published: October 2016

Neste artigo pretendemos compreender a visão de futuro da Amazônia que é apresentada no discurso historiográfico de Arthur Reis. Analisando diversos textos escritos por este historiador amazonense durante a década de 1950, pudemos inferir que, para ele, a região amazônica estava destinada a ser o espaço de uma sociedade “desenvolvida” e com uma economia de base agrícola. Observando a produção intelectual deste período, pudemos igualmente concluir que tal horizonte de expectativa era compartilhado por vários outros autores e políticos. Destacamos, ainda, que aquela apregoada destinação da Amazônia foi amplamente utilizada para legitimar intervenções estatais cuja meta era

Cotidiano, consumo e vida urbana em cidades médias brasileiras
Authors: Góes Eda Maria
Published: October 2016

Partindo do pressuposto de que o consumo é o meio a partir do qual as práticas espaciais podem ser apreendidas na atualidade, a perspectiva da análise adotada nesse artigo é a da “Geografia da vida cotidiana”, que valoriza o papel de cada citadino como sujeito no processo de produção do espaço urbano, o que nos levou a realização de um conjunto de 89 entrevistas com moradores de seis cidades médias brasileiras (Marília, Presidente Prudente, Ribeirão Preto, São Carlos e São José do Rio Preto - SP, e Londrina – PR). Com base na sua análise, as lutas travadas no campo do consumo e o papel fundamental dos espaços foram evidenciados, observando-se que a casa, seus equipamentos e o veículo individual estruturam um permanente e renovável sistema de objetos, que assumiu autonomia e atua na reprodução das desigualdades sociais. Como conclusão principal, constata-se que a ampliação do acesso ao mercado imobiliário, de eletrodomésticos e de veículos, ocorrido no Brasil desde os anos 1990, mas principalmente nos anos 2000, possibilitou a difusão da representação da classe trabalhadora, como consumidora e produtora de vida urbana, ao mesmo tempo em que a normalização do consumo, as práticas individuais de lazer e a localização periférica das residências favoreceram o controle social, especialmente nessas cidades médias nas quais espaços públicos, sindicatos, manifestações políticas e mesmo “o botequim da esquina” exercem cada vez menos atração.

Favela, criminalité violente et politique à Rio de Janeiro
Authors: Silva Luiz Antonio Machado da
Published: October 2016

Le texte est conçu comme un traitement empirique du processus sociopolitique d'intégration caractéristique de la ville de Rio de Janeiro. Est brièvement proposé un schéma concernant l'«aplatissement» des différends sur le contrôle social, en passant le développementalisme militarisé implanté par la dictature, qui était basée sur la doctrine de la «sécurité nationale», l'inquiétude généralisée au sujet des menaces qui pèsent sur la continuité des routines quotidiennes contenues les représentations collectives de la «violence urbaine» dont l'âme est associée à l'arrivée sur la scène de la criminalité liée au trafic de drogues illicites, la concurrence pour l'espace économique entre ses différents gangs et d'affrontements armés avec la/les police (s) . L'argument central est que, avec l'hyper-politisation de ce changement qui a eu lieu au début des années 1980, lors de la candidature au gouvernement de l'État de Leonel Brizola, une figure très controversée, cette nouvelle forme de conflit social basé sur ce qui a été appelé « métaphore de la guerre »a remplacé à l'ordre du jour le débat séculaire autour du « problème du bidonville » - leur place dans la ville - mais maintenant le thème comme une question liée au contrôle de la police répressive des périphéries urbaines. La superposition du «problème de la sécurité de tous les jours» au «problème des taudis» reproduit les processus traditionnels de ségrégation spatiale, mais maintenant la généralisation de la « peur du prochain », à côté de la présence dans les favelas de gangs de la drogue, réduit considérablement les chances le maintien de l'action collective locale et la popularisation de leurs demandes.
A Discrete Event-Driven Model for Electric Vehicles Predictive Charging
Authors: Ruzmetov Azizbek , Nait-Sidi-Moh Ahmed , Bakhouya Mohamed , Gaber Jaafar , Manier Marie-Ange
Published: October 2016

Very great research efforts have been made in the last decades to further develop and promote electric vehicles (EVs), their charging infrastructures, and operation techniques. However, little attention has been paid so far to the management of their charging planning, EVs assignment and mainly drivers' assistance to get into adequate charging stations (CSs). The charging planning and EVs assignment need to be predicted taking into consideration all operating constraints of charging systems including EV characteristics, status of CSs, road traffic, etc. This paper presents a discrete event driven model for EVs predictive charging. The authors mainly focus on behavior modeling of the charging system using (max, +) algebra and Petri nets. The model is then used to anticipate maximum charging times and charging rates of EVs while respecting their various constraints.
Public and Private Partner Selection in Battle of Sexes
Authors: Mariano Pedro , Nunes Davide , Correia Luís
Published: October 2016

In this paper the authors investigate what factors can promote population diversity. They compare different partner selection models and strategy mobility on the Battle of Sexes game. This is a game with a coordination dilemma where players must decide which event to attend given that each one has its preferred event but they prefer going together. They investigate two types of partner selection: one based in private information and another based on public information, which is based on an opinion model. The authors analyze two variants of the opinion model. Experimental analysis shows that partner selection plays a minor role of favoring population diversity. One of the most important factors is strategy mobility either implicitly through mutation or explicitly when an offspring is placed in a different location.
Towards Spike based Models of Visual Attention in the Brain
Authors: Kristensen Terje
Published: October 2016

A numerical solution of Hodgkin Huxley equations is presented to simulate the spiking behavior of a biological neuron. The solution is illustrated by building a graphical chart interface to finely tune the behavior of the neuron under different stimulations. In addition, a Multi-Agent System (MAS) has been developed to simulate the Visual Attention Network Model of the brain. Tasks are assigned to the agents according to the Attention Network Theory, developed by neuroscientists. A sequential communication model based on simple objects has been constructed, aiming to show the relations and the workflow between the different visual attention networks. Each agent is being used as an analogy to a role or function of the visual attention systems in the brain. Some experimental results based on this model have been presented in an earlier paper. The two approaches are at the moment not integrated. The long term goal is to develop an integrated parallel layered object model of the visual attention process, as a tool for simulating neuron interactions described by Hodgkin Huxley's equations or the Leaky-Integrate-and-Fire model.
Qualitative Case Study Research as Empirical Inquiry
Authors: Ellinger Andrea D. , McWhorter Rochell
Published: October 2016

This article introduces the concept of qualitative case study research as empirical inquiry. It defines and distinguishes what a case study is, the purposes, intentions, and types of case studies. It then describes how to determine if a qualitative case study is the preferred approach for conducting research. It overviews the essential steps in designing qualitative case study research, including the role of literature and theory, approaches for collecting data and analyzing it, as well as how to write up and present case study findings. It articulates how to avoid common pitfalls when engaging in qualitative case study research and concludes with the strengths and limitations associated with this form of empirical inquiry.
Institutional Ethnography
Authors: Wright Ursula T. , Rocco Tonette S.
Published: October 2016

This paper introduces institutional ethnography (IE) as a useful and systematic process for examining organizations and work data through the lens of stakeholders, at different levels, and considering the different forces at play. Drawing from ethnomethodology, IE focuses on how everyday experience is socially organized. Ideological shifts have changed the view of research as purely technical and rational to one of social practice embedded in particular cultural, political, and historical contexts. Research has translated into partially unsuccessful practice because it negates individuals' unique experiences based on race, ethnicity, class, and gender, allowing for a monolithic view to become the given reality for all those who live in today's society. Because adult vocational education is practiced in a highly charged political context, amongst a nexus of interconnected and interdependent social processes such as federal and state legislation, program funding and planning, literacy work, and employment training, discourse sets the parameters for a person's ability or inability to navigate the structural and political subsystems that impact learning, teaching, and work. Power is critically important as an analytic focus which crosses boundaries providing researchers a view of social organization that illuminates practices that marginalize.
Puzzling the Picture using Grounded Theory
Authors: Bennett Elisabeth E.
Published: October 2016

Since the first publication by Glaser and Strauss in 1967, Grounded Theory has become a highly influential research approach in the social sciences. The approach provides techniques and coding strategies for building theory inductively from the “ground up” as concepts within the data earn relevance into an evolving substantive theory. Over time, Grounded Theory has undergone development and adaptations, and the first phases of analysis have been successfully applied to other types of inductive approaches, such as basic qualitative and case studies. The methodological literature can be difficult to navigate for new researchers as well as experienced analysts using the approach for the first time. This article synthesizes the work of various seminal scholars to address the value of grounded theorizing and it builds a picture of what it means to do grounded theory.
An Exploratory Study on the Influencers of the Perceived Relevance of CIO's Activities
Authors: Varajão João , Trigo António , Soto-Acosta Pedro
Published: October 2016

Over the past decades several studies aimed to rank the importance of CIO's activities. One aspect that stands out in these studies is the difficulty in finding two studies that agree on the relative importance of CIO's activities. On the one hand, this can be explained by the CIO role evolution. On the other hand, there may be certain variables that influence the perception of the importance of CIO's activities. This paper presents the results of an exploratory study developed to identify the current CIO's main activities and to verify whether CIO's demographics and CIO's business context influence the perception of the importance of those activities. The results show that managing projects, interacting with top management teams, optimizing business processes and making strategic decisions are main CIO's activities; and the importance recognized to these activities is influenced by characteristics such as the CIO's age or the hierarchical structure of the organization.
Understanding The Key Attributes for a Successful Innovation Culture
Authors: Burdon Stephen , Kang Kyeong , Mooney Grant
Published: October 2016

This paper presents the results and findings of a research project on innovation culture in Australian information technology sector organisations. The primary objective of this study was to establish the determinants of a successful enterprise innovation culture in organisations with a strong industry reputation for radical innovation initiatives. The authors obtained 244 responses from 102 member organisations of the Australian Information Industry Association (AIIA). The survey explored the internal and external characteristics of a successful innovative organisation. Both employees' and competitors' perspectives on “what makes a particular organisation a successful innovator” were the main focus. The authors' findings indicated that the absence of a successful innovation culture is a serious impediment to growth and success. However, preferences for the key innovation culture attributes varied significantly by executive functions, size of the organization and type of ownership structure. Thus, a mix of key innovation attributes should be deployed and tailored to each organisation, based on their industry and strategic objectives.
The Value of Mobile Communication for Social Belonging
Authors: Henriques Sara , Damasio Manuel Jose
Published: October 2016

This paper deals with the relevance of mobile media in shaping online activities and patterns of interaction and its relation with industrial stakeholders and individual users' perspectives on the technology. The concepts of mediation and mediatization, as well as the processes of belonging and social cohesion are discussed and operationalized in the context of an empirical study. Data from mobile internet adoption and use will be discussed in the light of the above mentioned theoretical approaches. Two complementary views are approached –mobile internet stakeholders' and users'– encouraging a discussion on the interdependencies between individual adoption patterns and market derived determinants in a socio-cultural environment where technology adoption and diffusion happens. Results will provide contributions for the understanding of this type of technology adoption processes and the increasing importance of mobility in cultural and social practices, promoting an exciting discussion on the centrality of media nowadays and the current transformation processes society is undergoing.
Performance Analysis of Microarray Data Classification using Machine Learning Techniques
Authors: Pani Subhendu Kumar , Ratha Bikram Kesari , Mishra Ajay Kumar
Published: October 2016

Microarray technology of DNA permits simultaneous monitoring and determining of thousands of gene expression activation levels in a single experiment. Data mining technique such as classification is extensively used on microarray data for medical diagnosis and gene analysis. However, high dimensionality of the data affects the performance of classification and prediction. Consequently, a key issue in microarray data is feature selection and dimensionality reduction in order to achieve better classification and predictive accuracy. There are several machine learning approaches available for feature selection. In this study, the authors use Particle Swarm Organization (PSO) and Genetic Algorithm (GA) to find the performance of several popular classifiers on a set of microarray datasets. Experimental results conclude that feature selection affects the performance.
Evaluation of Multi-Target Human Sperm Tracking Algorithms in Synthesized Dataset
Authors: Arasteh Abdollah , Vahdat Bijan Vosoughi
Published: October 2016

Infertility is an important issue for many couples and male infertility is highly related to semen and spermatozoa which can be surveyed by means of semen/sperm analysis. Many fertility assessment laboratories are now equipped with automatic systems called Computer Aided Semen/Sperm Analysis (CASA) for doing this task. Evaluation of such systems is very important. In this research a web-based simulator is developed which facilitates evaluation of CASA systems. The developed software has many useful parameters such as blurring images or adding noise and it also gives full control of sperm counts and types. To illustrate performance of the developed simulator, many parameters such as spermatozoa population, standard deviation of Gaussian blur filter and noise intensity have been swept and the results of two well-known multi-target tracking systems (Linear Kalman Filter and Particle Filter) were compared and discussed.
Autonomous Systems in a Military Context (Part 1)
Authors: McFarland Tim , Galliott Jai
Published: October 2016

While some are reluctant to admit it, we are witnessing a fundamental shift in the way that advanced militaries conduct their core business of fighting. Increasingly autonomous ‘unmanned' systems are taking on the ‘dull, dirty and dangerous' roles in the military, leaving human war fighters to assume an oversight role or focus on what are often more cognitively demanding tasks. To this end, many military forces already hold unmanned systems that crawl, swim and fly, performing mine disposal, surveillance and more direct combat roles. Having found their way into the military force structure quite rapidly, especially in the United States, there has been extensive debate concerning the legality and ethicality of their use. These topics often converge, but what is legal will not necessarily be moral, and vice versa. The authors' contribution comes in clearly separating the two parts. In this paper, they provide a detailed survey of the legality of employing autonomous weapons systems in a military context.
Maximising Value Through IT and Business Alignment
Authors: Haider Abrar , Tang Sureerat Sae
Published: October 2016

Contemporary business organisations need to be responsive to internal as well as external changes. Organisational intuitiveness, being fundamental to this responsiveness, requires that these organisations develop and manage their information processing and management infrastructure to enable an integrated and informed environment. Organisations generally have a deterministic approach to technological infrastructure development and do not give requisite attention to soft factors that shape its use. Information technologies, however, are strategic resources that require supportive human action through appropriate set of roles, responsibilities, and decision rights to works effectively, evolve in use, and enable value on continuous basis. This paper presents a case of an information technologies governance in a financial services organisation. It highlights that governance practices need to be institutionalised in the organisation, such that they become an integral part of the organisational, social, and technical environment of the business.
Investment Location Selection based on Economic Intelligence and Macbeth Decision Aid Model
Authors: Bachrane Mostafa , Khaled Abdelilah , El Alami Jamila , Hanoune Mostafa
Published: October 2016

In this paper, the authors present a case study that aims to apply some sound MCDM techniques in the case of Economic Intelligence (EI) and show how the use of strategic information may help deciders to choose among geographic locations in which they could settle their investments. In this regard, the authors propose a new method that uses the multi-criteria decision support of MACBETH to tackle this issue. This method is used to rank thirteen countries likely to be chosen for location in order of preference from good to unfavourable. The integration of the MCDM in Economic Intelligence (EI) permits to rank countries of the Mediterranean according to their territorial competitiveness obtained through the global scores computed by the aforementioned technique of MACBETH. The results obtained allow the authors to affirm that France and Morocco have favourable strategic assets to attract foreign investment.
Personality Traits among Information Technology Officers and the Expectations of Human Resource Personnel
Authors: Singhapong Puckpimon , Winley Graham Kenneth
Published: October 2016

This study examined the importance assigned by Human Resource personnel to the personality traits of Information Technology officers. The extent to which these traits were evident among Information Technology officers was determined and compared to their level of importance among Human Resource personnel. The well-known 16 Personality Factors model was used and data was collected by questionnaire from 84 Information Technology officers working at operational levels in organizations and 64 Human Resource personnel with experience in the recruitment of Information Technology officers. For most of the traits the findings showed reasonable agreement between the level of importance of the traits according to the Human Resource personnel and the extent to which traits were evident among the Information Technology officers. However, there were differences with respect to the four traits Friendliness, Introversion, Sensitivity, and Intellect and the practical implications of these findings are discussed.
Representações sociais relacionadas aos professores homens do ensino fundamental e as inevitáveis associações às professoras
Authors: Gonçalves Josiane Peres , Oliveira Leonardo Alves de
Published: October 2016

Se comparado ao número de professoras mulheres, a presença de professores homens no ensino fundamental é proporcionalmente desigual. Partindo dessa premissa, este trabalho propõe-se a investigar as representações sociais de pais ou responsáveis de alunos matriculados nos anos iniciais do ensino fundamental da rede pública de educação de uma cidade do interior de Mato Grosso do Sul, Brasil, com relação à atuação profissional de professores homens nessa etapa da educação. Para tal, fez-se uso de análise de conteúdo, utilizando como instrumento entrevistas semiestruturadas. Foram identificadas três representações sociais mais frequentes nas manifestações discursivas das entrevistadas: o professor homem no ensino fundamental é mais respeitável, impõe respeito e/ou tem maior autoridade; o professor homem no ensino fundamental é mais equilibrado/racional; o professor no ensino fundamental é a figura paterna na escola. Em oposição às representações relacionadas aos professores homens, foram identificadas representações sociais relacionadas à atuação profissional de professoras mulheres. Os resultados indicam que funções da família são atribuídas aos profissionais da educação, incluindo os professores homens. Concluiu-se que, para as mães entrevistadas, a preferência por professores homens ou mulheres está mais associada ao cumprimento de funções familiares do que de funções próprias do educador.

Published: October 2016

Este texto, resulta de pesquisas realizadas pelo projeto Observatório da Educação Escolar Indígena/UEM-PR, financiado pela CAPES/SECADI/INEP, trata de alguns elementos que compõem a infância e a educação indígena, evidenciando aspectos históricos e destacando as brincadeiras, os jogos, sua importância e suas funções nas vivências familiares e na comunidade como elementos de aprendizagem e desenvolvimento. Reflete acerca de relatos produzidos por etnógrafos que tiveram contato com grupos indígenas do sul do Brasil, em meados do século XIX e início do século XX, e seus registros relativos à infância indígena junto aos grupos familiares, bem como apresenta alguns estudos recentes sobre a infância indígena, especialmente entre as etnias Kaingang, Guarani e Xetá.

Fatores determinantes da mudança voluntária da empresa de auditoria externa no mercado brasileiro
Authors: Rocha Junior Felipe Roberto , Rodrigues Sobrinho William Brasil , Bortolon Patricia Maria
Published: October 2016

O presente artigo teve como objetivo estudar os fatores que influenciam na decisão de mudança voluntária da empresa de auditoria. No Brasil há a exigência de substituição compulsória (rodízio) das empresas de auditoria, no mínimo, a cada 5 anos e com intervalos de 3 anos para a sua recontratação. Contudo, durante o período de adoção das normas internacionais de contabilidade, a Comissão de Valores Mobiliários – CVM, suspendeu essa exigência o que torna o período de 2010 a 2014 interessante para a investigação da pesquisa. Estudos que abordam o tema relacionam a decisão de substituição do auditor com variáveis relacionadas às características do auditor e o relacionamento com a empresa cliente; características da empresa e mudanças na alta gestão; e mecanismos de governança corporativa. A presente pesquisa investigou se essas variáveis explicam o respectivo fenômeno no mercado brasileiro, caracterizado pela concentração de controle e baixa proteção ao investidor minoritário. Os resultados sugerem que a emissão de relatório de auditoria modificado, o crescimento da empresa e a listagem no Novo Mercado ou Nível 2 da BM&FBovespa elevam a probabilidade de substituição dos auditores, enquanto a contratação de serviços extraauditoria reduz a probabilidade de mudança do auditor.

Published: October 2016

Este estudo analisa a relação entre a divulgação compulsória de informações financeiras e a suavização de resultados contábeis em empresas paranaenses de economia mista no período de 2010 a 2013. A argumentação teórica parte dos pressupostos da Hipótese dos Custos Políticos de Watts e Zimmerman (1978) e a Teoria da Agência. O estudo utiliza 34 empresas não financeiras de Economia Mista do Estado do Paraná. Para medir a suavização de resultados utilizou-se a métrica de Eckel (1981) e duas métricas de Leuz, Nanda e Wysocki (2003). Para mensurar a divulgação compulsória, foi elaborada uma métrica composta por 54 itens de natureza obrigatória pela Lei 6404/76. Os principais resultados indicam que a suavização de resultados e a divulgação compulsória não estão associados. Esperava-se que a suavização de resultados pudesse influenciar positivamente e significativamente os níveis de divulgação obrigatória das empresas de economia mista. Os resultados devem ser interpretados com precaução tendo em vista quatro razões. Primeiro, que as métricas para suavização de resultados baseiam-se em premissas subjacentes e que não estão isentas de erros de especificação ou mesmo de medida. Segundo, que a presença de suavização de resultados não significa necessariamente que é realizada de forma intencional, ou seja, pode simplesmente resultar das modificações das operações das empresas. Terceiro, pela natureza das informações ser obrigatória, os índices de divulgação deveriam ser elevados. Por último, que poucas são as pesquisas envolvendo Sociedade de Economia Mista e suas práticas contábeis, existindo muitas oportunidades de pesquisa em empresas de economia mista.

Este estudo objetivou verificar a relação entre a religiosidade e o raciocínio moral dos alunos de Ciências Contábeis, para isto, primeiramente descreveu-se a religiosidade e o raciocínio moral dos indivíduos, correlacionando-os em seguida. Para mensuração da religiosidade usou-se da Escala de Maturidade da Fé, desenvolvida por Benson, Donahue, Erickson (1993). Para mensuração do raciocínio moral usou-se o Defining Issues Test -2 elaborado por Rest e Narvaez (1998). A amostra resultou de 67 alunos concluintes do curso de Ciências Contábeis de duas universidades da Paraíba, e a confiabilidade interna dos instrumentos de pesquisa foi feita través do modelo definido por Cronbach (1951). Para averiguar a relação entre a religiosidade e o raciocínio moral utilizou-se o coeficiente de correlação não-paramétrico de Spearman (rs). Os resultados evidenciaram que a maioria dos respondentes tem sua fé classificada como integrada. Quanto ao raciocínio moral, a maioria dos respondentes foi classificada no nível de manutenção das normas, o que indica que para a maioria dos indivíduos o cumprimento das leis e normas é o mais importante. Ainda sobre o raciocínio moral, quando se analisou por tipo constatou-se que a maioria dos indivíduos se enquadrara no tipo 2 (Interesse Pessoal, mas em transição), os indivíduos deste tipo quando envolvido em dilemas morais, tendem a privilegiar seus próprios interesses. No que tange a relação entre religiosidade e raciocínio moral, constatou-se que não existem evidências relevantes que a confirme, uma vez que a relação entre ambas as variáveis não se mostrou significativa.
Urolitíase Canino

O sistema urinário é responsável pela filtração e eliminação de substâncias indesejáveis do organismo, que são eliminadas através da urina. Porém, se a urina apresentar com concentrações elevadas de minerais, pode originar uma urina supersaturada, o que predispõe a uma enfermidade conhecida como urolitíase. Em cães, as urolitíases representam cerca de 0,4 a 2% das consultas, acometendo mais animais entre 1 e 6 anos de idade. Ocorrendo com maior frequência na vesícula urinária e na uretra, os cálculos mais comuns são compostos de estruvita e oxalato de cálcio, sendo os sinais clínicos: hematúria, polaciúria, disúria, estrangúria. O diagnóstico é feito através de exame clínico associado à análise de exames complementares, como: urinálise, hemograma, exames radiográficos e ultrassonográfico. O tratamento é preferencialmente clínico, buscando a dissolução dos urólitos, porém, há casos em que o animal é submetido a procedimentos cirúrgicos. O método de prevenção é o uso de dietas específicas para evitar a ocorrência ou reincidência da afecção.
Potencial de plantas acaricidas no controle de carrapatos Rhipicephalus (Boophilus) microplus

Os carrapatos fazem parte do filo dos Artrópodes, pertencem à família Ixodidae, e destacam-se por sua importância toxicológica, através do parasitismo em aves e mamíferos, podendo utilizar o ser humano como hospedeiro. Dentre as espécies que mais causam adversidades, encontra-se a Rhipicephalus (Boophilus) microplus, popularmente conhecido como carrapato dos bovinos. Os produtos acaricidas disponíveis no mercado geralmente são sintéticos, e às vezes não eficazes contra esses parasitas, pois estes podem desenvolver resistência aos produtos, inviabilizando sua utilização,também, pelo alto risco de contaminação ambiental e humana. As plantas, por sua vez, são fontes de compostos bioativos provenientes do seu metabolismo secundário, sendo eficientes no controle do carrapato dos bovinos através da utilização de óleos essenciais e extratos das espécies vegetais. O objetivo deste trabalho foi fazer uma revisão da literatura a respeito de estudos sobre o uso de plantas com potencial acaricida, como métodos alternativos para o controle de carrapatosR.microplus, popularmente conhecido como carrapato dos bovinos.
