k-Skyband query answering with differential privacy
Authors: Chen Ling , Yu Ting , Chirkova Rada
Published: April 2018

Given a set of multi-dimensional points, a k-skyband query retrieves those points dominated by no more than k other points. k-skyband queries are an important type of multi-criteria analysis with diverse applications in practice. In this paper, we investigate techniques to answer k-skyband queries with differential privacy. We first propose a general technique BBS-Priv , which accepts any differentially private spatial decomposition tree as input and leverages data synthesis to answer k-skyband queries privately. We then show that, though quite a few private spatial decomposition trees are proposed in the literature, they are mainly designed to answer spatial range queries. Directly integrating them with BBS-Priv would introduce too much noise to generate useful k-skyband results. To address this problem, we propose a novel spatial decomposition technique k-skyband tree specially optimized for k-skyband queries, which partitions data adaptively based on the parameter k and performs finer partitions on the regions that are likely to contain k-skyband results. We further propose techniques to generate a k-skyband tree over spatial data that satisfies differential privacy, and combine BBS-Priv with the private k-skyband tree to answer k-skyband queries. We conduct extensive experiments based on two real-world datasets and three synthetic datasets that are commonly used for evaluating k-skyband queries. The results show that the proposed scheme significantly outperforms existing differentially private spatial decomposition schemes and achieves high utility when privacy budgets are properly allocated.
A novel quinoline-based fluorescent sensor for imaging Copper (II) in living cells
Authors: Zhou Chen , Liu Heng , Zhang Yinan
Published: April 2018

In this work, we synthesized a simple fluorescent molecule based on quinoline derivative. It displayed excellent sensitivity and selectivity toward copper ions. Upon addition of Cu2+, this molecule exhibited fluorescence quenching due to a fast electron transfer mechanism, the detection limit for Cu2+ of this sensor could be 6.17×10–7μmol L–1. Simultaneously, the cell imaging experiments were utilized to demonstrate its applicability in biological systems.
Charged System Search and Magnetic Charged System Search Algorithms for Construction Site Layout Planning Optimization
Authors: Kaveh Ali , Khanzadi Mostafa , Moghaddam Mohammad Rasteghar , Rezazadeh Mohammad
Published: April 2018

Construction site layout planning can be considered as an effort to place different temporary facilities in available site locations such that multiple objectives are satisfied as much as possible. With the extension of high-rise building construction and construction activities besides the lack of available spaces in construction sites, proper utilization of this resource has been highlighted because of its significant positive influences on direct cost, safety, and security of the site which consequently affects the total cost and schedule of the project. Thus the construction site layout planning is considered as one of the essential and important phases in construction projects. Site layout planning problem is an NP-Hard problem from the viewpoint of complexity. In this research, two prominent meta-heuristic algorithms, namely Charged System Search (CSS) and Magnetic Charged System Search (MCSS) are utilized to optimize the site layout planning problem. The obtained results of implementing these two algorithms for two different types of site space modeling are compared with the results of the Particle Swarm Optimization (PSO) algorithm and also those of the previous studies. The results illustrate the capability of the CSS and MCSS algorithms in solving the present problem.

Authors: Ahmed Tawfiq , Karim Md Rezaul , Khan Jahangir Haider , Moinuddin Shahriar
Published: April 2018

Objective: The Neurological injury is an important complication after coronary artery bypass surgery (CABG). The incidence of neurocognitive impairment after cardiac surgery varies from 20% to 80%. In this study we tried to analyze this difference of neurologic dysfunction between On-pump CABG and Off-pump CABG (OPCAB).Methods:This is a case control study done in National Institute of Cardiovascular Disease (NICVD), Dhaka during the period of July 2012 to June 2014. Sixty Patients with Ischemic heart disease were the study population. Group- A includes 30 patients underwent on pump CABG, Group-B 30 patients underwent OPCAB. All the patients of both the groups were followed up to 2 month’s postoperatively to find out any neurological and neurocognitive dysfunctionby observing motor function, sensory function,Mini Mantel state (MMS) Examination, orientation, memory, attention and calculation, recall and language test.Results: Neurocognitive dysfunction in the early postoperative period is significantly different among the groups.Neurocognitive dysfunction was more in Group A in comparison to Group B, On 3rd and 8th POD the MINI Mental Scores were found to be significantly lower in On-pump group than those in Off-pump group (22.0 ± 5.28 vs. 25.67 ± 3.34, p = 0.002 and 25.93 ± 3.11 vs. 26.63 ± 2.50, p = 0.023 respectively).This neurocognitive dysfunction gradually improved by the end of two month postoperative period. Only 6.66% patient in Group-A was found neurocognitically dysfunctional and was referred to neurophysician for further treatment. In case of OPCAB Group, no patient suffered fromneuorocognitive dysfunction.Conclusion: This study has convincingly shown cardio-pulmonary bypass (CPB) has had detrimental effect on neurocognitive function in patients who underwent CABG.Cardiovasc. j. 2018; 10(2): 186-193

Background: The Ankle-Brachial Index has been shown to be a good marker of systemic atherosclerosis and a powerful indicator of cardiovascular morbidity and mortality This study evaluated the relation of ABI with the angiographic severity of patient with coronary artery disease.Methods: This is a hospital based cross-sectional analytical study. 100 adult Bangladeshi patients who were admitted and underwent coronary angiography according to inclusion and exclusion criteria were the study population. All patient’s ABI were measured and coronary angiography were done. Patients were divided into two groups according to ABI. Group I with ABI >0.90 and group II with ABI <0.90.Results: In group I 65(82.2%) were men and 16(19.8%) were women. In group II 18(94.7%) patients were men and 1(5.3%) was women. Significant co-relation was found between low ABI and severity of CAD. Low ABI group showed more severe form of CAD with higher prevalence of triple vessel diseases, significant stenosis and more involvement of left main (LM) and left anterior descending(LAD)artery. Single vessel disease was found more with normal ABI. Hypertension, diabetes mellitus and Low ABI showed predictors of significant severe stenosis of coronary arteries.Conclusion: Low ankle brachial index is a predictor of the severity of coronary artery disease. So it could be incorporated in our day to day clinical cardiology practice as non-invasive, bedside test to assess and predict the severity of coronary artery disease.Cardiovasc. j. 2018; 10(2): 201-205

Published: April 2018

Arteriovenous malformation (AVM) is a rare congenital condition of the brain. In majority of cases AVMs remain asymptomatic and silent till it ruptures. But it can be a cause of cerebral haemorrhage, stroke, seizures, moderate to severe headache, loss of vision, aphasia, numbness or weakness of limbs. In current study, revealed a 25 years age patient of AVM admitted in Department of Neurosurgery at National Institute of Neurosciences (NINS) on December, 2013 with the complaints of loss of consciousness two times before admission, history of generalized seizure started over left side, headache for 2 years and vertigo for 1 year. Following admission the patient was evaluated clinically including all neurological examinations. All routine investigations were done. The patient was further evaluated by MRI, CT scan, CTA. Arteriovenous malformation was found in left frontal region. Under G/A nidus was excised totally in a single mass. Post MRI had shown the total removal of the AVM. Histopathological findings also revealed arteriovenous malformations. The post-operative period was uneventful and patient improved satisfactorily. He was found neurologically stable in follow up after 3 months. These researchers reported this case for its rarity and effective diagnosis and treatment by surgery.Journal of National Institute of Neurosciences Bangladesh, 2017;3(1): 62-66
“Entre el deseo de perpetuidad y la necesidad de renovación: sobre el reclutamiento de decuriones y la estabilidad de las aristocracias locales en los siglos II y III d. C.”
Authors: Melchor Gil Enrique
Published: April 2018

Partiendo del análisis de los mecanismos de acceso a los senados locales durante el Alto Imperio y tomando como modelo las curias de Irni y Canusium, constatamos cómo las élites municipales controlaron, al menos parcialmente, la entrada de nuevos miembros en el ordo decurionum desde finales de la etapa republicana, sin que por ello se dejara de admitir a candidatos de origen plebeyo. Diversos condicionantes demográficos, sociales y económicos hicieron necesario renovar periódicamente los ordines decurionum mediante la introducción de homines novi. Pese a lo señalado, disposiciones como la recogida en Digesto, L, 2, 7, 2 contribuyeron a que los miembros de los senados locales pudiesen favorecer las carreras políticas de sus descendientes. Finalmente, planteamos que el ingreso en las curias de menores de veinticinco años y de alieni, durante los siglos II y III d. C., no debe ser interpretado como síntoma de una precoz crisis de la vida municipal o del inicio de la decadencia de las aristocracias locales, sino como una muestra de la vitalidad de este grupo social, cuyos miembros continuaron compitiendo por el acceso a los honores hasta el siglo III d. C.
Aceh-Penang Maritime Trade and Chinese Mercantile Networks in the Nineteenth Century
Authors: Wong Yee Tuan , Lee Kam Hing
Published: April 2018

Aceh, as the world’s largest producer of pepper in the nineteenth century and exporter of areca nut, had a long and sustained trade connection with Penang. Among its major imports through Penang were cloth, rice, opium and fire-arms. Trade with Penang led to the rise of a wealthy group of ulèëbalangs who were able to assert their autonomous status vis-à-vis the Acehnese sultan. Penang was where many Acehnese took refuge when conflict broke out between the sultanate and the Dutch in the latter part of the nineteenth century. Penang became Aceh’s main access to the outside world not only in trade but also in diplomacy as foreign intervention was sought in its conflict with the Dutch. In this dynamic Aceh-Penang connection, the Chinese were important. This article recaptures the inter-ethnic and transnational co-operation and competition in maritime trade that significantly and profoundly shaped the commercial and political landscapes of nineteenth-century Aceh and Penang.
Silenced Fighters: An insight into Women Combatants’ History in Aceh (17th-20th c.)
Authors: Clavé Elsa
Published: April 2018

Le silence des combattantes : un aperçu de l’histoire des inong balèë à Aceh (XVIIe-XXe s.).

La résistance féminine est présentée par l’historiographie comme un trait caractéristique de l’histoire d’Aceh. Pourtant, l’existence et le rôle des femmes combattantes, les inong balèë, ont presque été niés dans le conflit entre le Mouvement pour la libération d’Aceh (Gerakan Aceh Merdeka – GAM) et l’État indonésien (1976-2005). Le présent travail soutient la thèse selon laquelle une image héroïque de la femme combattante a été créée par l’historiographie et que loin de représenter la réalité, elle a eu un impact dommageable sur la reconnaissance contemporaine des femmes combattantes. L’article retrace l’implication des femmes acihaises dans la politique, en distinguant trois grandes époques. Tout d’abord le XVIIe siècle, à propos duquel les historiens juxtaposent le mythe de l’amirale Malahayati à la réalité du règne des quatre sultanes (1641-1699). Ensuite le XIXe siècle, avec les héroïnes Tjut Njak Dhien (1850-1908) et Tjut Meutia (1870-1910), dont les images magnifiées occultèrent l’existence d’autres figures féminines qui combattirent les Hollandais (1873-1912). Enfin, la guerre d’indépendance (1942-1945), où des femmes du peuple s’illustrèrent, tout comme lors du récent conflit, où elles apportèrent un soutien essentiel au GAM dès 1998.
The traditional Sitting Song-Dances: How their Recognition and Rivalries Affect Gayo-Acehnese Relations at Home and in the Diasporas
Authors: Kartomi Margaret J. , Cowen Zelman
Published: April 2018

From the 1960s, both the Gayo minority in the highlands of Aceh and the Acehnese majority living in the coastal plains have achieved increased national and international exposure of their traditional song-dances, some of which are performed in the “ standing” position and others in the “ sitting” position. This article focuses on the Gayo saman and the Acehnese ratôh duek (lit. “ sitting chattering”) song-dances, both of which are performed in the sitting (actually kneeling) position. From ca the 1980s they were transplanted into the Medan, Jakarta and Yogyakarta diasporas. While ratôh duek was widely performed and taught in simplified form to thousands of Indonesian school children, saman has remained an exclusively Gayo traditional form, and unlike the Acehnese, its community has consistently rejected any substantial modification of the genre for mass teaching and performance purposes. In 2011, UNESCO formally recognised the Gayo Lues style of saman as an Endangered Item of Intangible Cultural Heritage, which increased its international prominence and provided some funding for its preservation. However this recognition served to intensify existing tensions between the Gayo and the Acehnese at home and especially in the diasporas. To this day, the government, the media and the general population often mistakenly refer to the Acehnese genre ratôh duek by the Gayo name of saman, despite its very different history and style. This is resented by the Gayo, who see the practice as an appropriation that increases their perception of being treated as second-class citizens in their own homeland as well as in their diaspora communities. ratôh duek (lit. “ sitting chattering”) song-dances, both of which are performed in the sitting (actually kneeling) position.

Triaxiality Inhibitors in N-body Simulations
Authors: Barnes Eric I. , Dowling Evan
Published: April 2018

Numerous previous studies have investigated the phenomenon wherein initially spherical N-body systems are distorted to triaxial shapes. We report on an investigation of a previously described orbital instability that should oppose triaxiality. After verifying the instability with numerical orbit integrations that extend the original analysis, we search for evidence of the instability in N-body systems that become triaxial. Our results highlight the difficulty of separating dynamical process from finite-N effects. While we argue that our analysis points to the presence of the instability in simulated triaxial systems, discreteness appears to play a role in mimicking the instability. This suggests that predicting the shapes of real-world systems, such as dark matter halos around galaxies, based on such simulations, involves more uncertainty than previously thought.
Non-LTE Calculations of the Fe i 6173 Å Line in a Flaring Atmosphere
Authors: Hong Jie , Ding M. D. , Li Ying , Carlsson Mats
Published: April 2018

The Fe i 6173 Å line is widely used in the measurements of vector magnetic fields by instruments including the Helioseismic and Magnetic Imager (HMI). We perform non-local thermodynamic equilibrium calculations of this line based on radiative hydrodynamic simulations in a flaring atmosphere. We employ both a quiet-Sun atmosphere and a penumbral atmosphere as the initial one in our simulations. We find that, in the quiet-Sun atmosphere, the line center is obviously enhanced during an intermediate flare. The enhanced emission is contributed from both radiative backwarming in the photosphere and particle beam heating in the lower chromosphere. A blue asymmetry of the line profile also appears due to an upward mass motion in the lower chromosphere. If we take a penumbral atmosphere as the initial atmosphere, the line has a more significant response to the flare heating, showing a central emission and an obvious asymmetry. The low spectral resolution of HMI would indicate some loss of information, but the enhancement and line asymmetry are still kept. By calculating polarized line profiles, we find that the Stokes I and V profiles can be altered as a result of flare heating. Thus the distortion of this line has a crucial influence on the magnetic field measured from this line, and one should be cautious in interpreting the magnetic transients observed frequently in solar flares.
De la technique analytique à la sublimation
Authors: Porge Erik
Published: April 2018

La coalescence de la structure clinique avec le sujet supposé savoir, dont Lacan parle en 1969 dans D’un Autre à l’autre , et sur laquelle l’analyse doit opérer une coupure, se joue à deux niveaux : la structure du sujet supposé savoir et le rapport entre vérité et savoir. Ces structures inscrivent par elles-mêmes des divisions. La coalescence est un raccord qui masque la coupure mais en même temps en permet la révélation dans l’après-coup de l’analyse. Les deux versants de la règle fondamentale constituent une paire non symétrique dont la logique n’est pas duelle et elle fait écho aux lignes de coupure inhérentes à la structure de raccord, permettant ainsi de vérifier l’existence d’un tracé de coupure, autour d’un reste, l’objet a , que réalise la sublimation.
La règle fondamentale est un acte
Authors: Lambotte Marie-Claude
Published: April 2018

La règle fondamentale caractérise la psychanalyse dans la mesure où elle vise à laisser surgir ou, mieux, à laisser se « réaliser », les pensées inconscientes du patient. « Attention (également) flottante » pour le psychanalyste, exigence de dire tout ce qui « apparaît » pour le patient, elle demande cette suspension du jugement (une épochè ) qui permet aux énonciations de l’inconscient de produire ses effets de surprise. Avec Lacan, la place de sujet supposé savoir occupée par l’analyste élargit la question freudienne du refoulement à celle de l’origine du sujet, autrement dit du réel impossible à penser à l’advenue au langage. En dehors de tout idéalisme, la question de l’être du sujet ne peut se dire que d’un entre-deux, l’entre-deux des signifiants ménagé par la règle fondamentale, mais aussi l’entre-deux êtres de la question de l’origine. Aussi bien, la règle fondamentale se présente comme un acte psychanalytique duquel le sujet s’absente, acte qui demande au psychanalyste comme au psychanalysant, au-delà de la significativité du symptôme, qu’on s’y « intéresse » en tant que tel.
La sophistique et ses enjeux pour la psychanalyse
Authors: Constantopoulos Michel
Published: April 2018

Les sophistes ont voulu faire de l’art de l’éloquence un savoir transmissible, proposé aux jeunes Athéniens aisés, pour leur faciliter harangues et plaidoiries. Ce fut un art du semblant, posant le vraisemblable au lieu de la vérité. Ses effets révèlent un réel qui y fait trou, l’absurdité du lien social. Tout en mettant en cause les valeurs héritées des Ancêtres, la sophistique se disait moralement neutre, ne prenant appui que sur l’opinion, considérée comme fragile mais saine. Or cette référence de la vérité à autrui est également l’apanage du sophisme lacanien du temps logique : « Aucun ne touche au vrai, sinon par les autres. » Se déprendre de l’emprise de ses propres opinions devient dans ce nouveau sophisme l’enjeu d’une nouvelle approche de la vérité, que Lacan appellera plus tard « varité » : relative, mais dans son rapport aux autres.
Présentation de la conférence d’Ernst Simmel. « Le traitement psychanalytique en clinique »
Authors: Longé Thierry
Published: April 2018

Au nom d’Ernst Simmel, psychiatre et psychanalyste berlinois, est attachée la brève expérience de la première clinique psychanalytique. C’est oublier qu’il fut l’un des pionniers du traitement psychique des traumatismes de guerre et de la voie peu empruntée d’une médecine psychanalytique. L’élève de Freud et analysant de Karl Abraham assuma bientôt des fonctions majeures dans l’institut psychanalytique berlinois et au bureau de l’Association internationale des médecins socialistes. Chassé de son pays, il engagea une réflexion psychanalytique et politique sur l’antisémitisme et l’ascension de l’hitlérisme. En Californie, sa dernière destination, il poursuivit son enseignement et la structuration du mouvement psychanalytique local.

Le code des visas, un rempart assumé contre les migrants en quête de protection internationale
Authors: Parrot Karine
Published: April 2018

Le code des visas européen qui harmonise les conditions d’entrée et de court séjour des ressortissants tiers dans l’espace Schengen peut-il permettre à une famille syrienne d’entrer légalement en Europe pour y déposer une demande d’asile ? Telle est la question posée récemment à la Cour de justice de l’Union européenne qui, réunie en Grande Chambre, considère que non, le code des visas n’offre aucune voie légale d’accès au territoire européen pour les étrangers en quête de protection internationale. Alors que tous les États de l’Union sont parties à la Convention de Genève relative au statut des réfugiés et que la Charte des droits fondamentaux de l’Union européenne proscrit les traitements inhumains ou dégradants en même temps qu’elle consacre le droit d’asile, la Cour avalise ainsi, par un argumentaire fallacieux, la politique européenne des visas qui verrouille l’accès au territoire européen et contraint les personnes migrantes à risquer leur vie pour y accéder.

Paiement à l’acte/capitation : une réforme ébauchée mais avortée
Authors: Bras Pierre-Louis
Published: April 2018

La capitation a longtemps été considérée, par les experts et les économistes, comme une modalité de rémunération des médecins généralistes plus pertinente que le paiement à l’acte. Celui-ci est, en effet, susceptible de favoriser l’induction de la demande et l’inflation des dépenses. Toutefois depuis 2000, le niveau de prise en charge des français par les généralistes diminue ; l’incitation à l’activité, inhérente au paiement à l’acte, apparait désormais comme une propriété positive de ce mode de paiement. Il reste que le paiement à l’acte réduit la prise en charge au seul face à face médecin-patient et constitue un obstacle à la délégation de tâches et à la constitution d’équipes de soins de premier recours. A cet égard, la capitation paraît mieux adaptée à l’enjeu majeur de notre système de soins : assurer une bonne prise en charge des patients chroniques. Pour autant, l’attachement des médecins français au paiement à l’acte est tel que jusqu’à la moitié des années 2000, il est resté la modalité exclusive de rémunération des médecins généralistes. A partir de cette date, les pouvoirs publics dans le cadre des négociations avec le corps médical ont introduit une part de capitation. Néanmoins, la dernière convention médicale, celle de 2016, marque un coup d’arrêt par rapport à ce qui pouvait apparaître comme le ferment d’une transformation progressive de l’organisation de notre système de soins de premier recours.
A la recherche d’une fin de vie apaisée
Authors: Stasse François
Published: April 2018

La loi du 2 février 2016 accroît fortement les droits du patient à décider l’arrêt des soins qui lui sont prodigués en fin de vie. Elle autorise également, sous certaines conditions, les médecins à pratiquer une sédation afin que le patient achève sa vie sans souffrir. Ces importantes évolutions juridiques et médicales constituent-elles un point d’équilibre durable dans la législation française ? Les exemples étrangers ne permettent pas de trancher avec certitude.
Demander un titre de séjour pour raisons de santé : que sait-on des systèmes de santé des pays d’origine ?
Authors: Charpak Yves , Chaix-Couturier Carine , Danzon Marc
Published: April 2018

L’obtention d’un titre de séjour pour raisons de santé comprend deux critères médicaux d’évaluation des demandeurs, dont l’un est une appréciation de la capacité ou non du pays d’origine à pouvoir le cas échéant fournir les soins nécessaires. Selon la loi, les médecins de l’Office français de l’immigration et de l’intégration (OFII), organisés en collège de trois sont chargés de cette évaluation médicale. L’OFII a donc souhaité mettre en place pour ses médecins une Bibliothèque d’Information Santé sur les Pays d’Origine (BISPO). L’article décrit les prérequis d’une telle information, les étapes de l’élaboration d’un outil pertinent et opérationnel pour la mise en œuvre de cette politique publique spécifique et les questions qui restent posées pour le futur.

Authors: Saiz Lourdes , Pérez Miguel David , Manzanedo del Campo Miguel Ángel
Published: April 2018

Purpose: The purpose of this paper is to study the absorptive capacity types in the knowledge management literature and aims to understand how companies can strength their contexts of cooperation in order to innovate.Design/methodology/approach: A balanced panel of 1,220 firms that respond to the Survey of Business Strategies for a three-year period was used, which represents a total of 3,660 observations.  Findings: The justification of absorptive capacity typology for an innovation efficiency process. The influence of the potential and realized absorptive capacity on new products is significant and causes effects on internal research and development in diverse way. The impact of the joint ventures, suppliers’ cooperation and customers’ cooperation are significant on absorptive capacity.Research limitations/implications: It would be interesting to extend the research to another innovation metrics as new organizational methods, new processes, new designs or new methods in the use of sales channels.Practical implications: The agreement of cooperation activities constitutes an important decision for the firm’s innovation. Companies must be conscious that while suppliers and customers’ cooperation are relevant cooperation actions to increase the internal research and development, joint ventures and customers’ cooperation are significant to the growth of the new products.Social implications: The types of absorptive capacity and internal research and development serve as mediating mechanisms between cooperative activities and innovative performance.Originality/value: This paper advances the literature on absorptive capacity by showing how firms use their positions of technological vigilance and management to form their capabilities, and subsequently, to enhance innovation outcomes. This study considers it is necessary to analyze the typology of the absorptive capacity that can allow managers to understand an innovation efficiency process in the cooperation context and make better decisions. The confluence of cooperation activities, absorptive capacity and organizational objectives in internal research and development obtain higher innovative results.

Best practices in road transport: An exploratory study
Authors: Fernández Vázquez-Noguerol Mar , González-Boubeta Iván , Domínguez-Caamaño Pablo , Prado-Prado J. Carlos
Published: April 2018

Purpose: Road transport aspects are becoming increasingly important due to their high impact on economic, environmental and social sustainability. Considering the triple bottom line approach, best practices play a fundamental role within organisations. The purpose of this paper is to analyse several sustainable initiatives in road transport adopted by companies.Design/methodology/approach: The findings were developed and evaluated based on empirical data captured through a survey of 98 professionals involved in logistics and transport activities. Additionally, key literature on transport initiatives was reviewed to supplement the framework for the implementation of best practices in road transport.Findings: The exploratory study shows the importance of each best practice and determines the level of implementation of each initiative, comparing the results among different dealers (retailers, wholesalers, carriers and manufacturers), type of transport fleet and companies’ revenues.Research limitations/implications: The sample of 98 companies was based on simple search filters and the group is not wholly representative of all sectors. Respondents were mainly managers from Spain involved in logistics and transport activities. Surveyed companies included manufacturing, retailers, wholesalers and third-party logistics providers.Practical implications: The most common best practices in road transport are identified, including initiatives related to: efficiency, reusability, safety, optimization, emissions, waste and recycling. Initiatives that influence road transport are ranked by their degree of implementation in the companies analysed. Social implications: Implementation of some of these best practices may help lessen negative impacts of road transport on society and the environment.Originality/value: The study results indicate which practices are most frequently used and their level of implementation depending on companies’ roles in the supply chain, revenues and types of transport fleet. By implementing the proposed best practices, companies will adopt sustainable behaviors to improve their transport performance.
Identification of reverse logistics decision types from mathematical models
Authors: Cortés Pellicer Pascual , Alarcón Valero Faustino
Published: April 2018

Purpose: The increase in social awareness, politics and environmental regulation, the scarcity of raw materials and the desired “green” image, are some of the reasons that lead companies to decide for implement processes of Reverse Logistics (RL). At the time when incorporate new RL processes as key business processes, new and important decisions need to be made. Identification and knowledge of these decisions, including the information available and the implications for the company or supply chain, will be fundamental for decision-makers to achieve the best results. In the present work, the main types of RL decisions are identified.Design/methodology/approach: This paper is based on the analysis of mathematical models designed as tools to aid decision making in the field of RL. Once the types of interest work to be analyzed are defined, those studies that really deal about the object of study are searched and analyzed. The decision variables that are taken at work are identified and grouped according to the type of decision and, finally, are showed the main types of decisions used in mathematical models developed in the field of RL.    Findings: The principal conclusion of the research is that the most commonly addressed decisions with mathematical models in the field of RL are those related to the network’s configuration, followed by tactical/operative decisions such as the selections of product’s treatments to realize and the policy of returns or prices, among other decisions.Originality/value: The identification of the main decisions types of the reverse logistics will allow the managers of these processes to know and understand them better, while offer an integrated vision of them, favoring the achievement of better results.

El objetivo de esta investigación ha sido analizar la construcción de la máquina eólica para desaguar terrenos pantanosos diseñada por Agustín de Betancourt y Molina en 1789. Para ello, se ha realizado un análisis estático por elementos finitos a partir del modelo tridimensional obtenido con Autodesk Inventor Professional. Los resultados muestran que las mayores tensiones del mecanismo se producen cuando el eje principal está engranado con la corona dentada, concretamente, en el punto de contacto entre el tornillo sinfín y dicha corona. Sin embargo, los máximos desplazamientos y las mayores deformaciones tienen lugar en las palas impulsoras. Asimismo, el mecanismo está sobredimensionado, no alcanzando en ningún punto la tensión de rotura del material, confirmando la acertada construcción de esta invención histórica.
The relation between religion and state in Islam and Christianity in the rise of ISIS
Authors: Van Aarde Timothy A.
Published: April 2018

The recent development of the Islamic State (ISIS 2010–2014 and IS 2014) is a radicalisation of the relation between religion and state in Islam. The relation of religion and state to Christianity has been shaped by the philosophy of dualism and Greek thought in the West. The relation of religion and state in Islam, however, has been shaped by a completely different tradition and conflicting view than Western thought and is based on the codified system of Shari’a law in Arabic thought. One of the most debated topics in Islamic studies is the inseparable nature of religion and state in Islam and the role of Shari’a law to the state. In the West the historical debate concerns the indiscriminate blending of church and state and the separation of church and state as indispensable to democracy and the modern question of the relation of Christian morality and public law. Islamic fundamentalism is a political and religious reform movement that indiscriminately blends the political and religious.
Implementation of disability policy framework in Namibia: A qualitative study
Authors: Shumba Tonderai W. , Moodley Indres
Published: April 2018

Background: This study explores some of the experiences of national programme managers, heads of national organisations of persons with disabilities (OPDs) and persons with disabilities in the implementation of the disability policies and legal framework in Namibia.Method: In-depth interviews were conducted with multiple key stakeholders mentioned above. Interviews were digitally recorded and transcribed verbatim. The Community Based Rehabilitation (CBR) matrix (health, education, livelihood, social and empowerment) was utilised to guide the development of themes and subthemes.Results: Twenty-one key informants participated in the study. Participants stated that while Namibia has made significant progress in addressing the medical and social needs of persons with disabilities, further progress can be achieved through better coordination, capacity building, review and updating of policies which allows for the inclusion of personal assistance, access to justice, improving supply chain management for a wide range of assistive devices, mainstreaming HIV prevention and treatment programmes, improved access to sexual reproduction and family planning, improved access to higher education, curricula reviews and effective monitoring and evaluating of the CBR programme.Conclusions: The study revealed key issues that need to be addressed in reviewing the policy and legal framework so that it is responsive to the current needs of persons with disabilities. Further, the CBR programme needs an evaluation tool to assess its effectiveness and efficiency in meeting the needs of persons with disabilities and also to elicit their experiences and satisfaction.
The use of Xbox Kinect™ in a Paediatric Burns Unit
Authors: Lozano Eleonora I. , Potterton Joanne L.
Published: April 2018

Background: The popularity of video game use in burns rehabilitation has grown because, in addition to facilitating maintenance of range of motion (ROM), the virtual imaging characteristics of these games provide distraction from pain.Objectives: The effect of using Xbox Kinect™ as an adjunct to physiotherapy in a Paediatric Burns Unit (PBU) has not been established. This study aimed to investigate the effect of using the Xbox Kinect™ on outcomes of children in the PBU at Chris Hani Baragwanath Academic Hospital.Methods: This non-equivalent, post-test only control group study took place over a period of 14 months. The control group received standard physiotherapy management and the experimental group received standard physiotherapy management and additional Xbox Kinect™. Outcome measures were ROM, Activities Scale for Kids (ASK©p) and a modified Wong-Baker FACES® enjoyment rating scale. Outcomes were assessed at discharge and then 1 week post-discharge at the usual follow-up appointment.Results: Sixty-six children participated in this study. More than 50% of the burns were because of hot water, followed by flame burns (30%) and electrical burns (12%). The addition of Xbox Kinect™ was effective in achieving higher active ROM (AROM) between discharge and follow-up (p < 0.01). Fun and enjoyment (p < 0.01) was found to be significantly higher in the children who participated in Xbox Kinect™. Total body surface area (TBSA%) (p = 0.03), age (p = 0.05) and AROM (p = 0.04) were significantly associated with ASK©p scores.Conclusion: The use of the Xbox Kinect™ has been shown to be a beneficial and useful adjunct to burns rehabilitation in this paediatric burns population.Clinical implications: Currently, there is limited information and research on interventions for children with burns in South Africa. The addition of Xbox Kinect™ to standard physiotherapy in-patient care was both enjoyable and effective and should be considered where funding is available.
Submandibular lipoblastoma: Case report of a rare tumor in childhood

Published: April 2018

Lipoblastoma is a rare, benign tumor usually occurring in childhood. It is essentially localized in the extremities and trunk, with few cases reported in the neck. We report the case of a 2-year-old girl with a rapidly enlarging, painless neck mass. Magnetic resonance imaging (MRI) revealed a 3-cm mass in the right submandibular region. Review of literature, diagnostic methods, and genetics of lipomatous tumors are discussed. Complete surgical excision via a lateral cervical approach demonstrated a white soft tissue with an adherent ganglion. Histology and immunohistochemistry confirmed the diagnosis of lipoblastoma. Cervical lipoblastoma is rare, and typically asymptomatic, rarely causing nerve compression or airway obstruction. MRI can help identifying the lipomatous nature of the mass, but the findings can be inconsistent due to variable maturity of fat cells and the mesenchymal content of the tumor. Diagnosis is always based on pathological examination. Further chromosomal analysis is useful in differentiating lipoblastoma from liposarcoma. Complete surgical excision is the recommended treatment.
A Taxonomy and Survey of IoT Cloud Applications
Authors: Pflanzner T. , Kertesz A.
Published: April 2018

Internet of Things (IoT) systems are realized by dynamic global network infrastructure with self-configuring capabilities, in which things can interact and communicate in the environment through the Internet by exchanging sensor data, and react autonomously to events generally without direct human intervention. Such systems can be utilized in many application areas, thus they may have very dierent properties. There is a growing number of cloud providers oering IoT-specific services, since cloud computing has the potential to satisfy IoT needs such as standardizing the custom data structures of the devices, processing and visualization tasks. IoT application developers do not only have to decide which cloud provider to use, but they also have to choose which combination of protocols and data structures best fits their application. As a result, it is necessary to know what properties these systems have and to learn to what extent cloud providers support IoT capabilities. In this paper, we address these issues and investigate 23 IoT cloud use cases and perform a detailed classification of them in a survey, and introduce a taxonomy of IoT application properties based on this survey. We also compare current cloud providers supporting IoT capabilities and gather requirements for IoT device simulation to support further research on IoT application development.

Abstract. The molecular composition of the water-soluble fraction of secondary organic aerosol (SOA) generated from the ozonolysis of α-phellandrene is investigated for the first time using high-pressure liquid chromatography coupled to high-resolution quadrupole–Orbitrap tandem mass spectrometry. In total, 21 prominent products or isomeric product groups were identified using both positive and negative ionisation modes, with potential formation mechanisms discussed. The aerosol was found to be composed primarily of polyfunctional first- and second-generation species containing one or more carbonyl, acid, alcohol and hydroperoxide functionalities, with the products significantly more complex than those proposed from basic gas-phase chemistry in the companion paper (Mackenzie-Rae et al., 2017). Mass spectra show a large number of dimeric products are also formed. Both direct scavenging evidence using formic acid and indirect evidence from double bond equivalency factors suggest the dominant oligomerisation mechanism is the bimolecular reaction of stabilised Criegee intermediates (SCIs) with non-radical ozonolysis products. Saturation vapour concentration estimates suggest monomeric species cannot explain the rapid nucleation burst of fresh aerosol observed in chamber experiments; hence, dimeric species are believed to be responsible for new particle formation, with detected first- and second-generation products driving further particle growth in the system. Ultimately, identification of the major constituents and formation pathways of α-phellandrene SOA leads to a greater understanding of the atmospheric processes and implications of monoterpene emissions and SCIs, especially around eucalypt forests where α-phellandrene is primarily emitted.

Abstract. Extremely high particle extinction coefficients, an order of magnitude higher than after the Mt. Pinatubo eruption in 1991, were measured in the stratosphere over Leipzig, Germany, on 22 August 2017. In a series of two articles, we present our observations of this record-breaking smoke event. In part 1 (Ansmann et al., 2018), we provide an overview of the smoke situation. The particle extinction coefficients reached 500 Mm−1 at 532 nm in the lower stratosphere around 15 km height and the smoke-related aerosol optical thickness (AOT) was close to 1.0 around noon. In part 2, we present the optical and microphysical properties of the fire smoke observed in a tropospheric layer from 5–6.5 km height and in a stratospheric layer from 15–16 km height. Three Raman lidars were run at Leipzig after sunset on 22 August. As a highlight, triple-wavelength polarization/Raman lidar measurements of the particle depolarization ratio and extinction-to-backscatter ratio (lidar ratio) at all three important lidar wavelengths of 355, 532, and 1064 nm could be performed. Very different particle depolarization ratios were found in the troposphere and in the stratosphere. The obviously compact and spherical tropospheric smoke particles caused almost no depolarization of backscattered laser radiation at all three wavelength (
