Published: September 2016

The past two decades have seen a significant advancement in the detection, classification, and understanding of exoplanets and binaries. This is due, in large part, to the increase in use of small-aperture telescopes (<20 cm) to survey large areas of the sky to milli-mag precision with rapid cadence. The vast majority of the planetary and binary systems studied to date consists of main-sequence or evolved objects, leading to a dearth of knowledge of properties at early times (<50 Myr). Only a dozen binaries and one candidate transiting Hot Jupiter are known among pre-main-sequence objects, yet these are the systems that can provide the best constraints on stellar formation and planetary migration models. The deficiency in the number of well characterized systems is driven by the inherent and aperiodic variability found in pre-main-sequence objects, which can mask and mimic eclipse signals. Hence, a dramatic increase in the number of young systems with high-quality observations is highly desirable to guide further theoretical developments. We have recently completed a photometric survey of three nearby (<150 pc) and young (<50 Myr) moving groups with a small-aperture telescope. While our survey reached the requisite photometric precision, the temporal coverage was insufficient to detect Hot Jupiters. Nevertheless, we discovered 346 pre-main-sequence binary candidates, including 74 high-priority objects for further study.
OUR SKY NOW AND THEN: SEARCHES FOR LOST STARS AND IMPOSSIBLE EFFECTS AS PROBES OF ADVANCED EXTRATERRESTRIAL CIVILIZATIONS
Authors: Villarroel Beatriz , Imaz Inigo , Bergstedt Josefine
Published: September 2016

Searches for extraterrestrial intelligence using large survey data often look for possible signatures of astroengineering. We propose searching for physically impossible effects caused by highly advanced technology by carrying out a search for disappearing galaxies and Milky Way stars. We select ∼10 million objects from USNO-B1.0 with low proper motions (μ < 20 mas yr−1) imaged on the sky in two epochs. We search for objects not found at the expected positions in the Sloan Digital Sky Survey (SDSS) by visually examining images of ∼290,000 USNO-B1.0 objects with no counterpart in the SDSS. We identify some spurious targets in the USNO-B1.0. We find one candidate of interest for follow-up photometry, although it is very uncertain. If the candidate eventually is found, it defines the probability of observing a disappearing-object event in the last decade to less than one in one million in the given samples. Nevertheless, because the complete USNO-B1.0 data set is 100 times larger than any of our samples, we propose an easily accessible citizen science project in search of USNO-B1.0 objects that have disappeared from the SDSS.
THE SPECTRAL ENERGY DISTRIBUTION OF THE COLDEST KNOWN BROWN DWARF*
Authors: Luhman K. L. , Esplin T. L.
Published: September 2016

WISE J085510.83–071442.5 (hereafter WISE 0855–0714) is the coldest known brown dwarf (∼250 K) and the fourth-closest known system to the Sun (2.2 pc). It has been previously detected only in the J band and two mid-IR bands. To better measure its spectral energy distribution (SED), we have performed deep imaging of WISE 0855–0714 in six optical and near-IR bands with Gemini Observatory, the Very Large Telescope, and the Hubble Space Telescope. Five of the bands show detections, although one detection is marginal (S/N ∼ 3). We also have obtained two epochs of images with the Spitzer Space Telescope for use in refining the parallax of the brown dwarf. By combining astrometry from this work and previous studies, we have derived a parallax of 0.449 ± 0.008″ (2.23 ± 0.04 pc). We have compared our photometry for WISE 0855–0714 to data for known Y dwarfs and to the predictions of three suites of models by Saumon et al. and Morley et al. that are defined by the presence or absence of clouds and nonequilibrium chemistry. Our estimates of Y − J and J − H for WISE 0855–0714 are redder than colors of other Y dwarfs, confirming a predicted reversal of near-IR colors to redder values at temperatures below 300–400 K. In color–magnitude diagrams, no single suite of models provides a clearly superior match to the sequence formed by WISE 0855–0714 and other Y dwarfs. Instead, the best-fitting model changes from one diagram to the next. Similarly, all of the models have substantial differences from the SED of WISE 0855–0714. As a result, we are currently unable to constrain the presence of clouds or nonequilibrium chemistry in its atmosphere.

The direct measurements of interstellar matter by the Interstellar Boundary Explorer (IBEX) mission have opened a new and important chapter in our study of the interactions that control the boundaries of our heliosphere. Here we derive for the quantitative information about interstellar O flow parameters from IBEX low-energy neutral atom data for the first time. Specifically, we derive a relatively narrow four-dimensional parameter tube along which interstellar O flow parameters must lie. Along the parameter tube, we find a large uncertainty in interstellar O flow longitude, 76.°0 ± 3.°4 from χ
2 analysis and 76.°5 ± 6.°2 from a maximum likelihood fit, which is statistically consistent with the flow longitude derived for interstellar He, 75.°6 ± 1.°4. The best-fit O and He temperatures are almost identical at a reference flow longitude of 76°, which provides a strong indication that the local interstellar plasma near the Sun is relatively unaffected by turbulent heating. However, key differences include an oxygen parameter tube for the interstellar speed (relation between speed and longitude) that has higher speeds than those in the corresponding parameter tube for He, and an upstream flow latitude for oxygen that is southward of the upstream flow latitude for helium. Both of these differences are likely the result of enhanced filtration of interstellar oxygen due to its charge-exchange ionization rate, which is higher than that for helium. Furthermore, we derive an interstellar O density near the termination shock of

cm−3 that, within uncertainties, is consistent with previous estimates. Thus, we use IBEX data to probe the interstellar properties of oxygen.

Published: September 2016

Au cours des années 2000, l’économie brésilienne a décollé, la croissance étant tirée notamment par la forte demande en matières premières de la Chine. En une décennie, la classe moyenne brésilienne est passée de 30 % à 50 % de la population. Les dirigeants politiques ont connu des taux de popularité exceptionnels. En 2013, le vent a tourné. Le taux de croissance est aujourd’hui en berne et la classe politique est engluée dans des scandales de corruption. Un rebond du Brésil est toutefois possible.
Colombie : la longue marche vers la paix ?

Le conflit qui oppose la guérilla des FARC à l’État colombien a fait 220 000 morts entre 1958 et 2012, date à laquelle des négociations de paix ont démarré à La Havane. Les forces armées colombiennes ont conduit une campagne de contre-insurrection efficace qui a fortement affaibli les FARC. En juin 2016, gouvernement et rebelles ont signé un accord historique. Le cessez-le-feu paraît néanmoins fragile et la paix reste à construire.
Europe : Back to the Future

Le Brexit est le symptôme d’une crise du projet européen. Les peuples d’Europe ne se reconnaissent pas dans la bureaucratie bruxelloise et tendent à se replier sur leur pré carré national. Toutefois, la coopération intergouvernementale fonctionne mal, comme l’a notamment montré la gestion de la crise des réfugiés. Les institutions européennes, telles qu’elles existent aujourd’hui, sont à bout de souffle. Seul un saut fédéral permettra de sortir de l’impasse.
Repenser l’Europe

L’Europe est aujourd’hui menacée par trois « ismes » : le djihadisme, le poutinisme et le populisme. Face à l’ampleur de la crise, les dirigeants des pays membres de l’Union européenne font pâle figure et ont beau jeu de blâmer Bruxelles. Après le choc du Brexit, le projet européen doit trouver un nouveau souffle. Le saut fédéral est, pour l’heure, une douce illusion. La priorité est de consolider l’existant, avant de pouvoir imaginer une nouvelle forme de concert des Nations européennes.
Lutte antiterroriste : comment s’adapte le Japon ?

Published: September 2016

Le Japon a subi plusieurs attentats sur son sol, notamment en 1995 avec l’attaque au sarin dans le métro de Tokyo. Plus récemment, deux ressortissants japonais ont été exécutés par l’État islamique en Syrie. Pour faire face à l’évolution de la menace, le dispositif antiterroriste japonais a été fortement renforcé. Le sommet du G7 d’Ise-Shima, en mai 2016, s’est déroulé sans incident. Le défi sécuritaire sera d’une autre ampleur en 2020 pour les Jeux olympiques de Tokyo.

Published: September 2016

En juillet 2015 a été conclu un accord sur le programme nucléaire iranien. Les restrictions imposées à Téhéran sont cependant en deçà des objectifs fixés par le Conseil de sécurité. Nombre d’analystes doutent de la sincérité des dirigeants iraniens et pensent que le temps joue en faveur de l’Iran. L’évolution des équilibres stratégiques au Moyen-Orient, de possibles changements à la tête du régime iranien et la détermination de la communauté internationale pèseront sur l’avenir de ce programme.
La personne âgée au croisement de l’éthique et de la bible
Authors: Lichtert Claude
Published: September 2016

La vieillesse comme naufrage ou plutôt comme promotion de l’autonomie de la personne âgée ? Des dérapages normatifs peuvent avoir lieu de nos jours. Les personnes âgées interrogent les plus jeunes. Nous tentons ici une alternative : accepter la dépendance sans infantilisation. Le champ sémantique du grand âge a évolué. Le vocabulaire biblique déjà avait évolué sur ce thème. Le Premier Testament oscille entre l’autorité du vieillard et la sagesse des aînés. Ainsi les livres sapientiaux ont- ils beaucoup à nous apprendre aujourd’hui sur nos vies qui cheminent ou sur la transmission inter-générationnelle, ou encore la frontière vie/mort jusqu’à la figure culminante de Jésus, dont la mort aura été si précoce.
Pour une éthique cosmothéandrique des vertus dans le contexte de la crise écologique
Authors: Valverde Campos Juan Carlos
Published: September 2016

« La Terre est malade », affirment aujourd’hui beaucoup de savants, fruit d’une vision du monde qui met par-dessus tout l’être humain, certains êtres humains, au détriment de la Vie comme un tout. Cette maladie n’est qu’un symptôme d’une autre crise plus grave, celle de l’être humain. La « crise écologique » pointe vers une « crise anthropologique » aussi tragique. Une société, avec le sens de la vie que les hommes se sont donné, est en crise. À la lumière de l’intuition cosmothéandrique de R. Panikkar, un renouveau semble s’imposer. Précisons que le vocable cosmothéandrique est composé de trois mots, à savoir, « cosmos », « théos » et « andros » désignant chacun un élément de la réalité en constante et inséparable relation. Tout comme dans La Trinité Divine, le Père, le Fils et le Saint Esprit sont en relation constitutive, R. Panikkar pense que la réalité qu’il appelle Radicale ou « Trinité Radicale » est aussi faite de relations constitutives entre le cosmos, Dieu et l’homme de telle manière que l’un ne peut pas exister sans les autres. Concernant la crise écologique, la théologie doit aussi s’interpeller : il faudrait donc remettre la théologie en chantier. Tout particulièrement l’éthique théologique. Il faudrait sans doute reprendre la notion de communauté et élargir ses frontières de façon à ce qu’on tienne compte aussi de la terre tout entière. Car tous ont le droit d’exister, indépendamment du bénéfice de l’être humain. Nous proposons, dans cet essai, de reprendre, à nouveaux frais, l’éthique des vertus dans le contexte de la proposition du philosophe et théologien espagnol, R. Panikkar, une éthique que nous appelons écosophique.
Psychanalyse et déconstruction

Lire, écrire, recevoir, correspondre. Comme on lit la psychanalyse, comme on lit un séminaire de psychanalyse, comme un apport de Derrida qui met encore et encore le texte de Freud au travail, comme on adresse une lettre... volée à la manière de Lacan lisant Edgar Allan Poe. Derrida s’adresse à la psychanalyse. Après Heidegger, il s’interroge sur la destruction de l’ontologie mais comme reconstruction de la pensée sur la question de l’Etre. Derrida, héritier d’Heidegger, en dialogue constant avec lui jusqu’aux Cahiers noirs  : question redoutable à affronter.
La théologie morale catholique et ses critiques dans l’entre-deux-guerres

Published: September 2016

Le dominicain Jean Tonneau (1903-1991) était théologien moraliste au Saulchoir. Il fut à la fois acteur et témoin de l’essoufflement de la morale catholique dans la seconde moitié du xx e siècle, notamment un certain thomisme. Il en fit le diagnostic, comme bien d’autres moralistes de ce temps, puis proposa des pistes raisonnées de renouvellement.
Residents' Positive and Negative Relationship Networks in a Nursing Home
Authors: Casey Anne-Nicole S. , Low Lee-Fay , Jeon Yun-Hee , Brodaty Henry
Published: September 2016

Person-centered care involves consideration of long-term care residents' lived experience, including social relationships. The current cross-sectional study investigated co-resident social networks in three units of a 94-bed Australian nursing home, including an 18-bed dementia-specific unit (DSU). Six care staff were interviewed. Chart, self-reported social isolation, and staff-reported social engagement data were collected for 36 residents ages 63 to 94 who consented to full participation. Fifty-five additional residents were included in observations. Median positive-to-negative network size ratios within units were 1.5:1 (Unit 1), 0.7:1 (Unit 3), and 0:1 (DSU). Moderate positive correlations existed between: perceived social support and total positive relationships [ρ(25) = 0.44,
p
= 0.03]; social withdrawal and total negative relationships [ρ(36) = 0.51,
p
= 0.002]; and objective social isolation and total negative relationships [ρ(22) = −0.44,
p
= 0.042]. Number and quality of relationships were associated with resident social withdrawal, perceived support, and isolation. High prevalence of isolation and negative relationships demonstrate the need for interventions. [

Cultural Connect for Tourism Development in BRIC Nations
Authors: Khanna Suvidha , Chauhan Vinay
Published: September 2016

BRIC forum is a word used to denote the four countries of the world, that is, Brazil, Russia, India, and China, and was created to strengthen the cultural cooperation between these nations vis-à-vis building political and economic areas. Lately South Africa also joined as a member in 2010. The BRIC Nations are expected to be the primary drivers of tourism growth. And one aspect of tourism growth that cannot be left out is the cultural connect. Therefore, this paper is a conceptual examination of how strong the cultures of the countries under the BRICs umbrella and what potential and opportunities does these Nations have to develop a cultural connect for tourism. The results of the study show that these nations are well endowed with good weather, extensive cultural and natural attractions, wildlife and a host of other opportunities. And in order to boost this industry, cultural coordination amongst all these nations is required, which can be achieved through establishing cultural circuit vis-a-vis establishing various international cultural events, may be in the form of business events. This will not only enhance the tourism but will also have a positive effect on the economy of these BRIC nations. Already the governments of all these nations are taking considerable steps in facilitating the tourists to visit these nations, which in turn is promoting tourism as well business.

Investigating Idiosyncratic Deals in the Indian Hospitality Industry
Authors: Dhiman Mohinder Chand , Budhwar Pawan S. , Katou Anastasia A.
Published: September 2016

This paper, utilising the social exchange theory, examines the relationship between before hiring negotiation (ex-ante) and after hiring negotiation (ex-post), idiosyncratic deals (i-deals) and employee reactions (i.e., motivation, commitment, work engagement and organisational citizenship behaviour). I-deals refer to voluntary, personalized agreements of a nonstandard nature negotiated between individual employees and their employers regarding terms that benefit each party. The hypotheses of the study were tested applying structural equation modelling on data collected from 275 employees working in 39 companies operating in the Indian hospitality industry. The findings show that although ex-ante and ex-post negotiations are interrelated, the negotiating special terms and conditions at the time of hire are less common than negotiating these terms and conditions while on job. Additionally, the findings indicate that ex-ante negotiation relates positively and more strongly to flexibility i-deals than to task and career i-deals, whilst ex-post negotiation relates positively but more strongly to career i-deals that to task and flexibility i-deals. The analysis also confirms the positive but differential effects of task, career and flexibility i-deals on employee reactions. Implications of the findings for both research and practice are discussed.
Culture and Authenticity Denominations in Bengali-Themed Restaurants

Published: September 2016

With contemporary consumer sampling diverse fragmented artefacts, mediating authenticity to such multifaceted and paradoxical identity is a growing challenge for the market. Focusing on Bengali-Themed Restaurants (BTRs), an exploratory study attempts to elicit the different versions in which cultural authenticity is crafted and refined by the market to cater the fluidity in modern identity. Based on purposive sampling, fifteen Bengali themed restaurants were shortlisted in the Indian metropolitan city Kolkata where occasion based visits were made across a period of two years (2012-14). A combination of participant observation and in-depth interview was employed in the study. The study gave rise to the concept of ‘market mediated authenticity' which describes the role market is able to influence objective or pseudo forms of authenticity. The study identified the emergence of BTRs with conservative consumption context by endorsing core traditional values and freezing the employed cultural practices; staged culture as a socially constructed and negotiable phenomenon by loading local culinary with new representations of time and place and existential authenticity depicting an extensive commercialized foothold in defining culinary culture. Market plays an intervening role in characterizing authenticity and procreating its multiple forms. Authenticity can be interpreted in terms of the market negotiation between multiple global and local cultural forces.
The Medical Tourism Industry in the BRIC Nations
Authors: Dogra Ajay Kumar , Dogra Pooja
Published: September 2016

Despite BRIC's roaring economic growth over the past decade, and its citizens' growing belief that it is finally ready to join the league of global superpowers by the end of 2020. With the progress of the IT revolution, advances in transportation and communication technology, the evolution of financial techniques, and the easing of restrictions on trade and investment, there has been a geometric increase in the international movement of people, products, money and information in the BRIC nations. The economic dynamism has led the emerging economies (BRIC countries) to diversify their business activities from a global perspective, and attempt to create optimal global value chains. Demand for tourism in Brazil, Russia, India and China is expected to grow in tandem with rapid economic growth. These nations are rich in natural and manmade resources and should cope quite well and have tremendous opportunities for the growth of tourism especially medical tourism between these nations. This chapter will explore BRIC member countries, on how they can cooperate to further promote the BRIC Vision and establish a viable healthcare initiative focusing on Indian medical tourism that will serve as a blueprint and model for other economies.

Authors: Dhiman Mohinder Chand , Kumar Sunil
Published: September 2016

This study attempts to explore the tourists' satisfaction within a tourism context, specifically with reference to the destination-based attributes. The study was conducted in India with a sample of Chinese tourists. Gathering data was analyzed by using t-tests. The research findings indicated that the dimension of accommodation services was the strongest predictor of the Chinese tourists' satisfaction, followed by incoming travel agency services and facilities in India. The dimension of accommodation services also was the strongest predictor of the female tourists' overall holiday satisfaction, followed by destination facilities and incoming travel agency services. Moreover, the mean scores of all the items within the main dimensions were above the neutral point. These results revealed that both male and female tourists were generally satisfied with their holiday in India.
Knowledge Management for E-Business Performance
Authors: Malhotra Yogesh
Published: September 2016

Within the last few years, the topic of knowledge management has gathered a

lot of interest in the corporate sectors. Although there is no commonly agreed upon

definition of knowledge management, companies, governments, institutions and

organizations are demonstrating an increasing interest in the topic. The key argument

of this chapter is that most current interpretations of knowledge management

are relevant to the industrial world of business of the past era. Given their origin in

the ‘old world’ of business, many such interpretations of knowledge management

may have serious and adverse implications for information strategy of enterprises,

governments and institutions.

The discussion surfaces the key assumptions about information strategy and

how they need to be considered afresh given the changing assumptions about

business strategy and competitive business environment. Based on this discussion,

a new perspective of knowledge management is proposed followed by suggestions

for the managers to effectively deploy it in the ‘new world’ of e-business. For the

purpose of this article, the focus of discussion is on e-business enterprises as most

observations are already evident in such organizations. However, most of the

arguments, observations and conclusions are also relevant to executives interested

in information strategy and business transformation for other post-industrial organizations

in the twenty-first century.
From Information Management to Knowledge Management: Beyond the "Hi-Tech Hidebound" Systems
Authors: Malhotra Yogesh
Published: September 2016

Most extant knowledge management systems are constrained by their overly rational, static and a contextual view of knowledge. Effectiveness of such systems is constrained by the rapid and discontinuous change that characterizes new organizational environments. The prevailing knowledge management paradigm limits itself by its emphasis on convergence and consensus-oriented processing of information. Strategy experts have underscored that the focus of organizational knowledge management should shift from 'prediction of future' [that cannot be computed] to 'anticipation of surprise.' Such systems may be enabled by leveraging the divergent interpretations of information based upon the meaning-making capability of human beings. By underscoring the need for synergy between innovation and creativity of humans and the advanced capabilities of new information technologies, this chapter advances current thinking about knowledge management.
Progressive-Stepping-Based Non-Dominated Sorting Genetic Algorithm for Multi-Objective Optimization
Authors: Baviskar Akshay , Krishnapillai Shankar
Published: September 2016

This paper demonstrates two approaches to achieve faster convergence and a better spread of Pareto solutions in fewer numbers of generations, compared to a few existing algorithms, including NSGA-II and SPEA2 to solve multi-objective optimization problems (MOP's). Two algorithms are proposed based on progressive stepping mechanism, which is obtained by the hybridization of existing Non-dominated Sorting Genetic Algorithm II (NSGA-II) with novel guided search schemes, and modified chromosome selection and replacement mechanisms. Progressive Stepping Non-dominated Sorting based on Local search (PSNS-L) controls the step size, and Progressive Stepping Non-dominated Sorting based on Utopia point (PSNS-U) method controls the number of divisions to generate better chromosomes in each generation to achieve faster convergence. Four multi-objective evolutionary algorithms (EA's) are compared for different benchmark functions and PSNS outperforms them in most cases based on various performance metric values. Finally a mechanical design problem has been solved with PSNS algorithms.
Multiobjective Group Search Optimization Approach for Community Detection in Networks
Authors: Arora Nidhi , Banati Hema
Published: September 2016

Various evolving approaches have been extensively applied to evolve densely connected communities in complex networks. However these techniques have been primarily single objective optimization techniques, which optimize only a specific feature of the network missing on other important features. Multiobjective optimization techniques can overcome this drawback by simultaneously optimizing multiple features of a network. This paper proposes MGSO, a multiobjective variant of Group Search Optimization (GSO) algorithm to globally search and evolve densely connected communities. It uses inherent animal food searching behavior of GSO to simultaneously optimize two negatively correlated objective functions and overcomes the drawbacks of single objective based CD algorithms. The algorithm reduces random initializations which results in fast convergence. It was applied on 6 real world and 33 synthetic network datasets and results were compared with varied state of the art community detection algorithms. The results established show the efficacy of MGSO to find accurate community structures.
A Hybrid Kernel Extreme Learning Machine and Improved Cat Swarm Optimization for Microarray Medical Data Classification
Authors: Chakravarty S. , Bisoi R. , Dash P. K.
Published: September 2016

This paper presents the pattern classification of the binary microarray gene expression based medical data using extreme learning machine (ELM) and its variants like on-line sequential ELM (OSELM) and kernel based extreme learning machine (KELM). In the KELM category two variants namely the wavelet based kernel (WKELM) extreme learning machine and radial basis kernel extreme learning machine (RKELM) along with support vector machine (SVMRBF) and support vector machine polynomial (SVMPoly) are used to classify microarray medical datasets. Further to reduce the high dimensionality of Microarray medical datasets giving rise to high number of gene expression and small sample sizes, a modified evolutionary cat swarm optimization (MCSO) technique is adopted. The efficiency of the proposed algorithm is verified using a set of performance metrics for four binary medical datasets belonging to breast cancer, prostate cancer, colon tumor, and leukemia, respectively.
DPM 2D Bar Code Locating based on Corner Detection and Clustering Analysis
Authors: Li Lingling , Gao Tao , Yang Yaoquan
Published: September 2016

Industrial DPM bar code is achieved by means of laser etching on metal surface; it uses Data Matrix bar code image as the main carrier, which can ensure the full life cycle tracking ability. But due to the ambient light and metal materials, collected industrial DPM images may exist uneven illumination, low contrast and other issues. How to identify this code type quickly and accurately is a problem, and how to locate the bar code area accurately is even more critical and difficult. In this paper, according to the characteristics of frequently appeared cartesian points in DPM bar code area, an adaptive corner detection method based on curvature scale space is used to detect the corners effectively. Then for the corners gathered by clusters, an improved density-based clustering method is proposed to achieve precise positioning results. Experimental results show that the proposed algorithm has certain suppression ability for low contrast, illumination and blur deformation images and is superior to the traditional algorithms on positioning precision and accuracy.
The Impact of Ownership Structure on Firm Performance
Authors: Yasser Qaiser Rafique , Al Mamun Abdullah
Published: September 2016

The connection between ownership structure and firm performance has attracted much attention, especially in emerging markets, yet yielded many inconsistent empirical results. This paper presents an analysis of the association between eight categories of ownership, HHI Index, GINI index and firm performance in Pakistan. Some researchers argue that ownership concentration can improve firm performance by making the owners more willing or able to monitor agents. In contrast, others argue that in the presence of efficient markets, market monitoring will discipline the managers. The author's results show that there is significant positive association with ownership structure and market based performance measure and economic profit. The ownership proportion of the institutional shareholding and foreign shareholding are also positively associated with firm performance. JEL Code: G32.
A Credible Cloud Service Model based on Behavior Graphs and Tripartite Decision-Making Mechanism
Authors: Tian Junfeng , Zhang He
Published: September 2016

The credibility of cloud service is the key to the success of the application of cloud services. The dual servers of master server and backup server are applied to cloud services, which can improve the availability of cloud services. In the past, the failures between master server and backup server could be detected by heartbeat algorithm. Because of lacking cloud user's evaluation, the authors put forward a credible cloud service model based on behavior Graphs and tripartite decision-making mechanism. By the quantitative of cloud users' behaviors evidences, the construction of behavior Graphs and the judgment of behavior, they select the most credible cloud user. They combine the master server, the backup server and the selected credible cloud user to determine the credibility of cloud service by the tripartite decision-making mechanism. Finally, according to the result of credible judgment, the authors could decide whether it will be switched from the master server to the backup server.
A Multidisciplinary Remote Healthcare Delivery System to Increase Health Care Access, Pathology Screening, and Treatment in Developing Countries
Authors: Edoh Thierry Oscar , Pawar Pravin Amrut , Brügge Bernd , Teege Gunnar
Published: September 2016

In this paper, the authors describe a case study of the poor access to healthcare in developing world, case of Benin, a West African developing country. The authors identify problems and the existing obstacles for applying standard Telemedicine and eHealth solutions. The authors particularly describe an adapted multidisciplinary remote care delivery system approach for improving and increasing the use of existing health services as well as the access to healthcare by overcoming some cultural, social, financial, and at least linguistic barriers. The multidisciplinary remote care delivery system integrates traditional practitioners, because most people are more confident with the traditional medicine. The authors further present a practical test which has shown that their approach has the potential to improve the quality and effectiveness of health care in rural and other concerned regions and also increase the accessibility to health care system.
Predicting Hypoglycemia in Diabetic Patients Using Time-Sensitive Artificial Neural Networks
Authors: Eljil Khouloud Safi , Qadah Ghassan , Pasquier Michel
Published: September 2016

Type-One Diabetes Mellitus (T1DM) is a chronic disease characterized by the elevation of glucose levels within patient's blood. It can lead to serious complications including kidney and heart diseases, stroke, and blindness. The proper treatment of diabetes, on the other hand, can lead to a normal longevity. Yet such a treatment requires tight glycemic control which increases the risk of developing hypoglycemia; a sudden drop in patients' blood glucose levels that could lead to coma and possibly death. Continuous Glucose Monitoring (CGM) devices placed on a patient body, measure glucose levels every few minutes. These devices can also detect hypoglycemia. Yet detecting hypoglycemia sometimes is too late for a patient to take proper action, so a better approach is to predict the hypoglycemic events ahead of time and alarm the patient to such occurrences. In this research, the authors develop a system that involves a special type of Artificial Neural Networks (ANN), the Time-Sensitive ANN (TS-ANN), to predict hypoglycemia events ahead of time and within a prediction horizon of thirty minutes. This period should be long enough to enable diabetic patients to avoid hypoglycemia by taking a proper action. A TS-ANN based system that is able to predict hypoglycemia events have been developed and tested with high accuracy results (average specificity of 98.2%, average accuracy of 97.6% and average sensitivity of 80.19% with a maximum value reaching 93%).
A Framework for Protecting Users' Privacy in Cloud
Authors: Sodiya Adesina S. , Adegbuyi B.
Published: September 2016

Data and document privacy concerns are increasingly important in the online world. In Cloud Computing, the story is the same, as the secure processing of personal data represents a huge challenge The main focus is to to preserve and protect personally identifiable information (PII) of individuals, customers, businesses, governments and organisations. The current use of anonymization techniques is not quite efficient because of its failure to use the structure of the datasets under consideration and inability to use a metric that balances the usefulness of information with privacy preservation. In this work, an adaptive lossy decomposition algorithm was developed for preserving privacy in cloud computing. The algorithm uses the foreign key associations to determine the generalizations possible for any attribute in the database. It generates penalties for each obscured attribute when sharing and proposes an optimal decomposition of the relation. Postgraduate database of Federal University of Agriculture, Abeokuta, Nigeria and Adult database provided at the UCIrvine Machine Learning Repository were used for the evaluation. The result shows a system that could be used to improve privacy in cloud computing.
Accurate Classification Models for Distributed Mining of Privately Preserved Data
Authors: Sumana M.  , Hareesha K.S.
Published: September 2016

Data maintained at various sectors, needs to be mined to derive useful inferences. Larger part of the data is sensitive and not to be revealed while mining. Current methods perform privacy preservation classification either by randomizing, perturbing or anonymizing the data during mining. These forms of privacy preserving mining work well for data centralized at a single site. Moreover the amount of information hidden during mining is not sufficient. When perturbation approaches are used, data reconstruction is a major challenge. This paper aims at modeling classifiers for data distributed across various sites with respect to the same instances. The homomorphic and probabilistic property of Paillier is used to perform secure product, mean and variance calculations. The secure computations are performed without any intermediate data or the sensitive data at multiple sites being revealed. It is observed that the accuracy of the classifiers modeled is almost equivalent to the non-privacy preserving classifiers. Secure protocols require reduced computation time and communication cost.
A Pedagogical Review of Programming Education Research
Authors: Xia Belle Selene
Published: September 2016

Previous research has shown that especially novice students may find learning programming to be difficult in terms of programming concepts and program design. Many students fail to write correct program codes after the course and achieve the level of skills set by the learning goals of the course. In order to overcome the challenges of learning programming, we are interested in the pedagogical techniques of learning and teaching programming as well as some of the learning tools used to support programming education. This knowledge would help us to better align the design of programming courses with the teaching goal of these courses. New research opportunities are opened in the field of contributing student pedagogy in programming education.

Health sciences professionals work on diverse health care teams and often face ethical dilemmas. Bioethics education in a distance-learning environment is one way that such individuals can obtain relevant, easily accessible, and academically rigorous instruction on ethical decision-making and behavior. Drawing on our expertise as distance educators in George Washington University's Health Sciences Programs, we discuss our experiences teaching bioethics online for health sciences professionals, assess the existing evidence of best practices in online bioethics education, and provide recommendations for future pedagogical research relevant to diverse health care professionals.
An Update On Best Practices and Regulatory Requirements for the Improvement of Clinical Laboratory Services through Quality
Authors: Mourtzikou Antonia , Stamouli Marilena
Published: September 2016

The aim of this study is to emphasize the need for accurate, relevant and reliable results provided by the clinical laboratories, in order to achieve the best patient outcomes. The improvement of clinical laboratory services through quality is a continuous process, which includes constant changes and new regulatory requirements. Further efforts must be made to raise the awareness of all health personnel involved in the total testing process and highlight the importance of quality indicator implementation for improving the quality of laboratory services and patient safety. Laboratories and physicians must audit, update and continuously e their critical result management practices in order to provide safe and reliable care to patients. Moreover, implementation of six-sigma, a state-of–the-art quality management strategy, can further improve laboratory quality, by identifying biased or imprecise assays, so that appropriate quality monitoring strategies can be used. Harmonization of the total testing process, as a process of recognizing, understanding, and explaining differences and taking steps to achieve uniformity of results is of utmost importance for the use of data obtained from different laboratories interchangeably.
Security Improvements for Better and Safer Cross-Border ePrescription and Patient Summary Services
Authors: Katehakis Dimitrios G. , Pangalos George , Prentza Andriana
Published: September 2016

Large-scale deployment of electronic Prescription and Patient Summary services (eP/ PS) is expected to enable seamless cross-border care and secure access to patient health information between European healthcare systems. Guaranteeing national readiness to support priorities, determined at the political level, is also considered a key prerequisite for the facilitation of access to health services across borders. This work focuses on required technological improvements to address reliability and quality challenges through the adoption of generic/ non-health specific building blocks (BBs) for basic cross-border public services in Europe. More specifically, what is presented is the introduction of generic components for non-repudiation, end point detection, and electronic identification, to effectively support the implementation of Directive 2011/ 24 on the application of patients' rights in cross-border healthcare. These interventions are considered to be necessary steps for the introduction of better quality, trustworthy, cross-border eP/ PS across Europe.
Patient Accessible EHR is Controversial

Published: September 2016

In Sweden, a national eHealth service providing Patient Accessible Electronic Health Records is now being widely deployed, with 400 000 users in January 2016. Although the Patient Data Act states that patients have a right to take part of their health records, the introduction has been controversial. Results from a pre-deployment questionnaire to record-keeping care professions in a healthcare region indicate that perceptions and knowledge differ not only between the professions but, more importantly, that knowledge about current eHealth development and action plans needs to increase as implementation will affect their work processes. Staff perceptions and knowledge are considered being some of the most important issues to handle during the implementation of eHealth services aiming to provide healthcare information and communication tools for patients and relatives. To cover the gaps, specific training is needed, and all record-keeping professionals need to be more involved in the implementation of such eHealth services.
A Novel Approach to Managing the Dynamic Nature of Semantic Relatedness
Authors: Choi Youngseok , Oh Jungsuk , Park Jinsoo
Published: September 2016

This research proposes a novel method of measuring the dynamics of semantic relatedness. Research on semantic relatedness has a long history in the fields of computational linguistics, psychology, computer science, as well as information systems. Computing semantic relatedness has played a critical role in various situations, such as data integration and keyword recommendation. Many researchers have tried to propose more sophisticated techniques to measure semantic relatedness. However, little research has considered the change of semantic relatedness with the flow of time and occurrence of events. The authors' proposed method is validated by actual corpus data collected from a particular context over a specific period of time. They test the feasibility of our proposed method by constructing semantic networks by using the corpus collected during a different period of time. The experiment results show that our method can detect and manage the changes in semantic relatedness between concepts. Based on the results, the authors discuss the need for a dynamic semantic relatedness paradigm.
Ethical and Managerial Aspects of Social Network Advertisement
Authors: Smith Alan D. , Offodile O. Felix
Published: September 2016

Social networking systems are relatively new to society and clarification on certain aspects of the system can be obtained through further research. There are many positive aspects of social networks, such as Facebook, that organizations could benefit from including stronger customer relationship management (CRM) techniques. On the other hand, questions are raised as to whether or not an organization who advertises on social networking systems experiences an increase in sales as a result. It is unclear whether or not these advertisements actually deter individuals from further using these types of social networking systems. If individuals who spend a large amount of time on social networking sites are deterred from further usage due to these advertisements, are there any benefits to them? Significant amount information can be relayed on Facebook, MySpace and Twitter, but the question remains whether or not organizations are using this to their advantage. The present study used a sample of working professionals that were knowledgeable in the various options of social networking to test these assumptions. The three hypotheses dealt with the interplay of online social networking, advertising effectiveness, gender and age trends, and remaining the interplay with positive comments of the use of the ‘like' function and its impacts on consumer behavior, as derived from the review of relevant operations literature and from applying the basic tenants of Uses and Gratification Theory. All three specific research hypotheses were accepted in the null form.
