Comment la croissance du revenu et le vieillissement influencent la demande de soins en Chine rurale ?
Authors: Audibert Martine , He Yong , Mathonnat Jacky
Published: May 2017

Nous estimons l’évolution de la demande de soins sous l’effet de la croissance du revenu et du vieillissement de la population en utilisant deux échantillons de patients issus de deux enquêtes menées dans les mêmes régions, à un intervalle de 18 ans (1989-2006). Nous nous intéressons au rôle spécifique des prix et de la distance aux établissements de santé. Les données proviennent de la base CHNS fournie par le « Carolina Population Center ». Nous utilisons un modèle logit multinomial mixte. Nous trouvons que les effets prix des soins se sont réduits sur la période et sont devenus plus hétérogènes. L’effet du vieillissement l’a emporté sur l’effet de la croissance du revenu, entraînant un effet distance croissant et une préférence accrue des patients pour la proximité des prestataires de soins. Cependant, pour faire face à l’urbanisation, la politique chinoise a consisté pendant de nombreuses années à privilégier les grands hôpitaux. Nos résultats suggèrent que cette politique a, d’une part, incité un plus grand nombre de patients à opter pour l’automédication et, d’autre part, qu’elle a contribué à accroître dans les années 2000 la charge que représentent les soins de santé pour les ménages les plus pauvres.

Le juste positionnement du juge pour enfants et de ses partenaires face aux conduites d’opposition des mineurs
Authors: Bégon-Bordreuil Laurence
Published: May 2017

Les conduites d’opposition des mineurs appellent de la part de l’institution judiciaire une réflexion sur son positionnement de façon à prendre en compte la dimension psychique de « l’agir ». Il apparaît adapté pour le juge d’incarner une « écoute tripolaire » marquée par une attention aux fragilités du mineur, une volonté de valorisation et une limite interdictrice. Un partenariat systémique et une continuité d’intervention dans le temps sont également des éléments essentiels. Il est pourtant à regretter que les réformes pénales de ces quinze dernières années renforcent uniquement le souci de répression au détriment des autres dimensions
L’enseignant face aux conduites d’opposition dans l’école
Authors: Brusa Mélina , Weber Margot , Le Run Jean-Louis
Published: May 2017

Les conduites d’opposition chez l’enfant apparaissent de plus en plus fréquentes sur la scène scolaire au fil des ans. Les enseignants observent différents degrés d’opposition, allant de refus plus ou moins actifs face au travail à des rejets complets du cadre scolaire, associés à des troubles des conduites importants. L’opposition se manifeste chez des enfants présentant des pathologies ou troubles spécifiques (troubles des apprentissages, hyperactivité, autisme, précocité intellectuelle, etc.) mais aussi chez des enfants sans handicap, invalidité ou trouble psychiatrique repéré. Le cadre scolaire lui-même, par les contraintes qu’il soustend et par le système d’évaluation, peut générer des conduites d’opposition. L’enseignant se retrouve parfois seul et démuni face à l’enfant et sa famille. Cette interview a pour objectif de recueillir les propos d’une enseignante expérimentée afin de comprendre davantage les enjeux de l’opposition à l’école, de mieux saisir les attitudes salutaires ou au contraire propices à amplifier les conduites d’opposition et enfin d’envisager les ressources internes ou extérieures à l’école dont les enseignants disposent lorsqu’ils sont confrontés à ce type de difficultés.
Sociohistoire des discours institutionnels sur l’éducation au Québec : une entrée à double voie dans la modernité
Authors: LeVasseur Louis
Published: May 2017

Les enjeux sociaux, culturels et pédagogiques reliés au système éducatif québécois font l’objet de continuels débats, dont les termes se stabilisent dans des discours institutionnels (officiels et consultatifs) visant à définir des politiques ministérielles. Cependant, tous ces enjeux et analyses ainsi que les recommandations et les politiques officielles qui s’ensuivent s’insèrent dans le cadre social et historique d’une modernité dont Habermas a examiné les principes et les apories qui sont, pour l’auteur, les mêmes que ceux des discours institutionnels québécois.

L’hybridation entre recherche et pratique : une condition pour faire progresser les pratiques de concertation d’un grand maître d’ouvrage
Authors: Ballan Étienne , Dziedzicki Jean-Marc
Published: May 2017

Il est courant qu’un maître d’ouvrage d’infrastructures fasse appel à des prestataires pour l’accompagner dans la mise en œuvre de dispositifs de concertation. Ce qui l’est moins, c’est lorsque maître d’ouvrage et prestataire s’engagent dans une forme de dialogue sur plusieurs années afin que le second aide le premier à progresser dans sa vision de la concertation. C’est de ce dialogue qui s’est construit progressivement entre l’équipe de concertants de Réseau ferré de France et celle de l’association Arènes que cet article rend compte. La spécificité de ce dialogue tient tout particulièrement à l’hybridation entre recherche et pratique des responsables de ces deux entités et à celle des réflexions et actions engagées, à la fois entre opérationnalité et questionnements/positionnements éthiques et stratégiques. L’article présente d’abord les différents cadres d’action et outils sur lesquels s’est appuyé ce dialogue : le débat public et sa concertation préparatoire, l’étude de contexte territorial, la charte de la concertation, les référentiels de la politique de concertation de l’entreprise. Il analyse ensuite les conditions et les principaux effets de cette collaboration : si cette expérience montre tout l’intérêt de missions conduites en lien avec des méthodes et des questionnements de recherche, elle témoigne également de la difficulté pour que leurs résultats imprègnent les choix stratégiques d’une entreprise publique.
Protéger l’enfant ouvrier. La loi du 19 mai 1874, une « législation intermédiaire » ?
Authors: Fiorentino Karen
Published: May 2017

La loi du 19 mai 1874, réglementant le travail des enfants et des filles mineures, est classiquement présentée comme une norme « intermédiaire » en histoire du droit du travail. Un certain mépris est attaché à ce qualificatif, donnant à penser que cette loi n’a guère compté et que, si elle est remplacée par celle du 2 novembre 1892, c’est bien la preuve qu’elle n’a guère fait montre d’une grande efficacité. Or, l’analyse des archives d’une circonscription donne à penser le contraire. L’étude de la mise en œuvre de la loi, dans le cadre de la troisième circonscription d’inspection, révèle au contraire que cette norme fut déterminante dans l’évolution des mentalités. Bien plus que par le travail du législateur, la condition des enfants en milieu industriel fut améliorée par le rôle central des inspecteurs, créés par la loi de 1874. Certes, la norme présente des lacunes, son champ d’application se révèle rapidement trop limité, mais cette norme représente un pan crucial de l’évolution des conditions de travail des enfants en usine. Ce travail permet également de mesurer l’importance du recours aux sources archivistiques, qui donnent une idée exacte de la mise en œuvre d’une loi, complément indispensable du texte législatif.
Moscou – Kazan – Oufa : Jean-Richard Bloch en 1941-1942
Authors: Stern Ludmila
Published: May 2017

Écrivain français communiste, Jean-Richard Bloch était probablement le seul intellectuel français à avoir demandé l’asile politique en URSS pendant la Seconde Guerre mondiale. L’expérience unique de son exil soviétique, partiellement reconstituée grâce à ses notes inédites, ainsi que celles de sa femme, gardées au Département des Manuscrits de la Bibliothèque nationale de France, commence par l’arrivée de Bloch en URSS et son séjour à Moscou (avril-octobre 1941), suivi de son évacuation vers l’Est à Kazan sous l’égide de l’Union des écrivains soviétiques (octobre-décembre 1941), et ensuite à Oufa où il sera mobilisé par l’Internationale Communiste pour lire ses Commentaires à la Radio du Komintern à destination de la France occupée (décembre 1941-décembre 1942). Après avoir examiné brièvement le développement des relations que Bloch entretenait avec l’Union des écrivains dans de nouvelles conditions de guerre, nous nous concentrerons sur les attentes du Komintern à l’égard de Bloch et de sa femme. La reconstruction des conditions de travail et de la qualité de vie de la « famille kominternienne » contribuera à la littérature limitée (Ceretti, Cauchy, Thorez-Vermeersch, Wieviorka) de la période à Oufa, et fera lumière sur les fonctions de Bloch, ainsi que son statut et ses interactions avec la direction de l’Internationale Communiste.
Des étudiants américains à Paris : un autre regard sur les relations culturelles France-États-Unis (de la fin des années 1940 aux années 1950)
Authors: Capdevila Elisa
Published: May 2017

Le GI Bill contribue, après la Seconde Guerre mondiale, au retour des artistes américains à Paris. Encore considérée par beaucoup comme la « Mecque des arts », la ville apparaît comme une étape importante dans la formation d’un jeune artiste. L’arrivée des Américains à Paris rappelle le prestige persistant de l’ancienne capitale des arts et son dynamisme retrouvé à partir de la fin des années 1940. Elle perpétue une tradition de formation parisienne fondée sur une relation inégale entre les États-Unis, pays jeune sans avant-garde propre à présenter au monde, et l’Europe, la France, plus particulièrement, considérée comme le berceau de l’art moderne. Mais le GI Bill est aussi, déjà, le cadre d’une évolution des relations artistiques entre le Vieux et le Nouveau continent. L’affranchissement des étudiants artistes à l’égard des maîtres parisiens qu’ils sont pourtant venus chercher annonce déjà l’indépendance future des arts américains ; leur bourse et leur statut de citoyens américains leur assurent une relative aisance qui accentue leur sentiment de liberté. Enfin, le traitement médiatique dont ils font l’objet conforte l’idée que le temps de l’expatriation parisienne doit prendre fin, instituant les États-Unis comme nouvelle puissance artistique sur la scène internationale.
Outcomes of 27-Gauge Vitrectomy-Assisted Choroidal and Subretinal Biopsy
Authors: Grewal Dilraj S. , Cummings Thomas J. , Mruthyunjaya Prithvi
Published: May 2017

BACKGROUND AND OBJECTIVE:

To report the initial experience of 27-gauge vitrectomy-assisted choroidal and subretinal biopsy

PATIENTS AND METHODS:

Retrospective, interventional case series. Eighteen eyes of 18 patients undergoing 27-gauge vitrectomy-assisted choroidal (n = 16) or subretinal biopsy (n = 2). Clinical and lesion characteristics, cytopathology, histology, gene expression profiling (GEP), visual acuity (VA), complications including vitreous hemorrhage (VH), development of rhegmatogenous retinal detachment (RD), and need for additional surgeries were analyzed.

RESULTS:

Indications were choroidal melanoma (n = 10), indeterminate choroidal (n = 5), and subretinal lesions (n = 3). Mean lesion height was 3.33 mm ± 1.55 mm (range: 0.80 mm to 6.75 mm) and largest diameter was 8.63 mm ± 4.14 mm (range: 3 mm to 15.5 mm). Mean number of intralesional biopsy passes required was 1.76 ± 0.83 (range: one to four). During a mean follow-up of 7.4 months ± 2.7 months (range: 4 months to 14 months), VA was unchanged (0.5 logMAR ± 0.6 logMAR vs. 0.7 logMAR ± 0.84 logMAR;
P
= .07). Pathologic diagnosis was obtained in 16 of 18 eyes (88.9%), and GEP data were collected for all 11 choroidal melanomas. Post-biopsy VH occurred in 13 of 18 eyes (72.2%) and was severe enough to require a concurrent limited vitrectomy in six eyes (33.3%). These eyes had a greater lesion height compared to eyes not requiring a vitrectomy (4.08 mm ± 1.68 mm vs. 2.76 mm ± 1.43 mm;
P
= .04). A rhegmatogenous RD requiring repeat surgery developed in two of 18 eyes (11.1%).

CONCLUSION:

The authors concluded that 27-gauge vitrectomy-assisted choroidal and subretinal biopsy established a diagnosis in 88.9% of eyes in lesions 0.8 mm or larger.

Computer Analysis of Pablo Picasso's Artistic Style
Authors: Burcoff Amanda , Shamir Lior
Published: May 2017

In the past few years, computational methods have been becoming increasingly more prevalent in art history. Such methods can reveal new knowledge about art, and provide a novel approach to the studying of art history based on quantitative evidence. Here we used computational analysis to study the artistic style of Pablo Picasso and its change throughout time. Experimental results show a strong correlation between the visual content and the time of painting, evidenced by the ability of the computer to estimate the time of creation by analyzing the visual content of the painting. It also showed that some of the paintings were estimated by the algorithm to be artistically related to a different time period than the time period in which they were painted. The most significant numerical image content descriptor for estimating the time of creation is the fractal structure of the painting, which changed during his career in a nearly linear fashion. The software used in the experiment is publicly available, as well as detailed instructions of using the software.
Robust Clustering with Distance and Density
Authors: Yuan Hanning , Wang Shuliang , Geng Jing , Yu Yang , Zhong Ming
Published: May 2017

Clustering is fundamental for using big data. However, AP (affinity propagation) is not good at non-convex datasets, and the input parameter has a marked impact on DBSCAN (density-based spatial clustering of applications with noise). Moreover, new characteristics such as volume, variety, velocity, veracity make it difficult to group big data. To address the issues, a parameter free AP (PFAP) is proposed to group big data on the basis of both distance and density. Firstly, it obtains a group of normalized density from the AP clustering. The estimated parameters are monotonically. Then, the density is used for density clustering for multiple times. Finally, the multiple-density clustering results undergo a two-stage amalgamation to achieve the final clustering result. Experimental results on several benchmark datasets show that PFAP has been achieved better clustering quality than DBSCAN, AP, and APSCAN. And it also has better performance than APSCAN and FSDP.
Employee Engagement Practices in IT Sector Vis-à-Vis Other Sectors in India
Authors: Tomar Jitendra Singh
Published: May 2017

Employee engagement is an important notion built around the concepts of job satisfaction, employee commitment, retention of talent, that impacts organizational performance. The disengaged employees lead to loss of productivity, procedural imbalances, and decreased efficacy. Organizations are addressing the work force and their job performance, task performance, organizational citizenship behavior, productivity, discretionary effort, effective commitment, and continuance commitment. Engaged employees are emotionally connected with their organization, and are enthusiastic about their job and success of the organization. The employment engagement practices are soulfully needed to understand the employee, give them healthier environment to work, let them grow professionally, award them, and keep them happy, irrespective of the business sector. This study intends to explore the employee engagement practices in Indian IT Sector and compare them with the engagement practices in other leading sectors in India. The study also assesses various engagement attributes in Indian IT organizations.
Human Resource Management and Security Policy Compliance
Authors: Choi Youngkeun
Published: May 2017

Given the regulatory requirements imposed on organizations within numerous industries, research in the area of employee compliance with organizational security and privacy regulations remains necessary and highly desirable. Therefore, the objective of this study provides a unique framework for understanding the influence of HRM practices on individual security policy compliance outcomes. The unit of analysis for this research project is the individual employee of a bank organization. With the survey of 257 bank employees, a components-based approach to structural equation modeling was taken. The results of this study indicate that developmental-oriented appraisal, externally or internally equitable reward, selective staffing and training for career development are positively associated with employees' behavioral intent to comply security policy through their affective commitment.
The Relevance of Social Sciences Teacher Education Programme in Preparing Effective Secondary School Educators
Authors: Goburdhun Seema , Ramsaha Jay
Published: May 2017

In Mauritius, the teaching of social studies presents educators with a unique set of challenges, as they are expected to have multi-disciplinary knowledge and multi-dimensional skills to be effective in classrooms. Many of these social studies educators have undertaken the PGCE (Post Graduate Certificate in Education) course offered by the Mauritius Institute of Education (MIE), which is the leading teacher training institute in the country. This paper explores the relevance of the social sciences teacher education programme offered by the MIE in preparing secondary school educators to meet the challenges in their practice in the wake of current curricular reforms. The study used focus group discussions as the main tool to gather in depth views of the participants. Preliminary findings tend to show that although educators may possess skills, lack of mastery in multi-disciplinary knowledge influences their proficiency in classrooms. An analysis of the different modules of the social sciences programme also shows a gap between the educators' needs and the modules offered.
Semantically Enabled Communication Framework for Autonomous Systems
Authors: Pasha Maruf
Published: May 2017

Multi-agent systems (MAS) have recently gained much fame and have proved to be a potential technology that enables the construction and development of collaborative intelligent software systems. Development of such autonomous intelligent systems require a high level of communication with enriched semantics that will enable them to be integrated with the Web to achieve the ultimate goal of the Semantic Web in the future. The most important issues in MAS are high-level agent interaction, expressive power of agents, and semantics of messages to collaborate and cooperate with each other in Autonomous Decentralized Systems (ADS). This encoding/decoding mechanism will not only increase the reliability of the system but will also exhibit the properties of ADS that are high assurance. The evaluation proves that the implementation of semantically enriched communication improves performance and efficiency as a whole.
A Survey of Risk-Aware Business Process Modelling
Authors: Lhannaoui Hanane , Kabbaj Mohammed Issam , Bakkoury Zohra
Published: May 2017

For organizations, risk is a key concept when dealing with business process. Integrating risks aspects during business process management starts with an accurate consideration of risk's characteristics in the modelling phase. Most research is needed on integrating risk and business process modelling. Actually, the literature suggests various approaches to represent risk-related information in business process models. The diversity of those methods and the fact that this domain is still emerging make it difficult to choose the most suitable language. This paper aims to represent a survey of the existing risk-annotated business process model's notations.
Activated Microglia Desialylate and Phagocytose Cells via Neuraminidase, Galectin-3, and Mer Tyrosine Kinase
Authors: Nomura Koji , Vilalta Anna , Allendorf David H. , Hornik Tamara C. , Brown Guy C.
Published: May 2017

Activated microglia can phagocytose dying, stressed, or excess neurons and synapses via the phagocytic receptor Mer tyrosine kinase (MerTK). Galectin-3 (Gal-3) can cross-link surface glycoproteins by binding galactose residues that are normally hidden below terminal sialic acid residues. Gal-3 was recently reported to opsonize cells via activating MerTK. We found that LPS-activated BV-2 microglia rapidly released Gal-3, which was blocked by calcineurin inhibitors. Gal-3 bound to MerTK on microglia and to stressed PC12 (neuron-like) cells, and it increased microglial phagocytosis of PC12 cells or primary neurons, which was blocked by inhibition of MerTK. LPS-activated microglia exhibited a sialidase activity that desialylated PC12 cells and could be inhibited by Tamiflu, a neuraminidase (sialidase) inhibitor. Sialidase treatment of PC12 cells enabled Gal-3 to bind and opsonize the live cells for phagocytosis by microglia. LPS-induced microglial phagocytosis of PC12 was prevented by small interfering RNA knockdown of Gal-3 in microglia, lactose inhibition of Gal-3 binding, inhibition of neuraminidase with Tamiflu, or inhibition of MerTK by UNC569. LPS-induced phagocytosis of primary neurons by primary microglia was also blocked by inhibition of MerTK. We conclude that activated microglia release Gal-3 and a neuraminidase that desialylates microglial and PC12 surfaces, enabling Gal-3 binding to PC12 cells and their phagocytosis via MerTK. Thus, Gal-3 acts as an opsonin of desialylated surfaces, and inflammatory loss of neurons or synapses may potentially be blocked by inhibiting neuraminidases, Gal-3, or MerTK.
Overexpression of Human CD55 and CD59 or Treatment with Human CD55 Protects against Renal Ischemia-Reperfusion Injury in Mice

Published: May 2017

Deficiency in the membrane-bound complement regulators CD55 and CD59 exacerbates renal ischemia-reperfusion injury (IRI) in mouse models, but the effect of increasing CD55 and CD59 activity has not been examined. In this study, we investigated the impact of overexpression of human (h) CD55 ± hCD59 or treatment with soluble rhCD55 in a mouse model of renal IRI. Unilaterally nephrectomised mice were subjected to 18 (mild IRI) or 22 min (moderate IRI) warm renal ischemia, and analyzed 24 h after reperfusion for renal function (serum creatinine and urea), complement deposition (C3b/c and C9), and infiltration of neutrophils and macrophages. Transgenic mice expressing hCD55 alone were protected against mild renal IRI, with reduced creatinine and urea levels compared with wild type littermates. However, the renal function of the hCD55 mice was not preserved in the moderate IRI model, despite a reduction in C3b/c and C9 deposition and innate cell infiltration. Mice expressing both hCD55 and hCD59, on the other hand, were protected in the moderate IRI model, with significant reductions in all parameters measured. Wild type mice treated with rhCD55 immediately after reperfusion were also protected in the moderate IRI model. Thus, manipulation of CD55 activity to increase inhibition of the C3 and C5 convertases is protective against renal IRI, and the additional expression of hCD59, which regulates the terminal complement pathway, provides further protection. Therefore, anti-complement therapy using complement regulatory proteins may provide a potential clinical option for preventing tissue and organ damage in renal IRI.
Not by human seed but born from above to become children of God: Johannine metaphor of the family or ancient science?
Authors: Draper Jonathan A.
Published: May 2017

This article provides a critical reflection on Jan van der Watt’s theory of the network of the metaphor of the family in John’s Gospel, taking the Johannine understanding of the seed as a case study. In his reflections on God’s act of creation, Philo uses the language of impregnation and (re)birth of the natural man by his divine seed to produce children of virtue for those who open themselves to divine wisdom. His Middle-Platonic construction is unlikely to have been understood as ‘absurd, irrelevant or untrue’, which characterises a metaphor in Van der Watt’s definition. The discourse on the relationship between seed/sperm and life reflects ancient ‘scientific’ understanding of the world for Philo and John’s Gospel. This article analyses the connections and differences between Philo’s conception and the mysticism of John’s understanding of rebirth from above as contrasted with ‘natural’ birth.

Glucose Transporter 1 Expression in Odontogenic Keratocyst, Dentigerous Cyst, and Ameloblastoma: An Immunohistochemical Study
Authors: Dash Kailash C , Bandyopadhyay Alokenath , Panda Abikshyeet , Behura Shyam S , Ramachandra Sujatha , Mishra Pallavi
Published: May 2017

Introduction

An array of odontogenic lesions manifest in the maxillofacial region with variable presentations. The biological behavior of lesions, such as odontogenic keratocyst (OKC), dentigerous cyst (DC), and ameloblastoma (AM) always invite debate. Glucose transporter 1 (GLUT-1) is proven to be an indicator of metabolic behavior of several benign and malignant neoplasms.

Aim

The purpose of this study was to evaluate the expression of GLUT-1 in OKC, DC, and AM to understand their metabolic behavior.

Materials and methods

Immunohistochemical expression of GLUT-1 was evaluated in each of the 15 cases of OKC, DC, and AM. The number of labeled cells, staining intensity, and membrane or cytoplasmic expressions were the parameters assessed and analyzed using chi-square test.

Results

All cases showed positive GLUT-1 expression: 86.6% OKC showed more than 50% labeled cells followed by DC (40%) and AM (26.5%); 53.3% OKC showed strong intensity in comparison to AM, which showed weak intensity in 53.3% cases; 86.6% of OKCs showed both membrane and cytoplasmic expression followed by DC (40%) and AM (26.6%), whereas 73.3% of AM showed only membrane expression followed by DC (60%) and OKC (13.3%).

Conclusion

Odontogenic keratocyst was found out to be more metabolically active followed by DC and AM.

Authors: Darout Ismail A , Alamir Abdulwahab , Sultana Sameena
Published: May 2017

Introduction

Osteoporosis is a systemic bone disease that can be prevented to some extent by awareness of its risk factors and related health behavior. The aim of this study was to collect information about knowledge and awareness of osteoporosis among women living in Jazan and to describe the type of food habits, sociodemographic characteristics, and other osteoporosis- related health behavior.

Materials and methods

Self-administered questionnaires were used for data collection. The total participants were 546 women: 88 (16.1%) were health professionals and 458 (83.9%) non health professionals in the age range ≤20 to 50 years. Data collection was facilitated by a trained intern female doctor of dentistry whose task was to administer the distribution and collection of the questionnaires.

Results

In total, 61.9% of health professionals and 54.3% of nonhealth professionals scored highly on knowledge of osteoporosis. The respondents of osteoporosis preventive food items were also highly knowledgeable with 50.6 and 52.6% of health and nonhealth professionals respectively. About 48.1% of health professional and 44.2% of nonhealth professional scored low on knowledge of osteoporosis behavior and attitude, vitamin supplements, and sunlight exposure. The age effect on osteoporosis knowledge was 33.8% in young age group and 30.7% in old age group.

Conclusion

Our study shows that Jazan women were highly knowledgeable and aware about osteoporosis and its related health behavior and that health professionals and nonhealth professionals were equally aware about osteoporosis-related health matters.

Clinical significance

Awareness and preventive behavior of osteoporosis can prevent or slow the development of the disease.

Aim

The aim of this preliminary study was to assess the chance of dental caries level using early childhood oral health impact scale (ECOHIS) in a group of 5-year-old children in Sri Lanka.

Materials and methods

A sample of school children aged 5+ years was taken for the study from Denuwara educational zone in Kandy District in Sri Lanka using probability proportional to size sampling method in 2010. Dental caries and oral health impact of the children were recorded. The mean decayed, missing, and filled teeth (DMFT) was 0.01 ± 0.3, while mean dmft was 3.7 ± 0.29. The mean decayed teeth (d) was 3.0 ± 0.23, the mean extracted teeth (m) was 0.46± 0.08, and the mean filled teeth (f) was 0.21 ± 0.05. Twenty four percent of them were caries free (95% confidence interval 0.17, 0.32). Ordinal logistic regression models were fitted by considering dmft levels as the response variables, and oral health impact as the predictor variable. Since Pearson test p-value and deviance test p-value are 0.99 (p > 0.05) and 0.986 (p > 0.05) respectively, the null hypothesis is not rejected as the model fitted the data adequately.

Conclusion

This model could be used to predict the chance of dental caries level with the score of ECOHIS. Therefore, ECOHIS can be taken as a reliable indicator to assess the level of dental caries.

In vivo Evaluation of Zirconia Abutments in Implant supported Restorations in Partially Edentulous Patients
Authors: Kapri Anita , Joshi Sudhir
Published: May 2017

Dental implants have been a universally accepted option for prosthetic rehabilitation of partially edentulous patients. Titanium implants abutments exhibit a dull grayish hue and give an unnatural appearance. Abutments based on zirconia are one of the alternatives to titanium abutments. To date, few comparative studies have reported on esthetic and biological outcomes of implant-supported restorations with zirconia abutments.

Purpose

To clinically evaluate the esthetic performance of zirconia abutments in implant-supported restorations.

Materials and methods

A total of 24 anterior implant sites were chosen for the placement of implants. A delayed loading protocol was followed; 12 zirconia abutments were placed along with 12 titanium abutments in the contralateral sites. Biological and esthetic variables were recorded by a periodontist and prosthodontist. The patients were followed 2 weeks, 1, 3, and 6 months postinsertion.

Results

All the data for Copenhagen index score and visual analog scale scores were evaluated by the prosthodontist at follow-up appointments; the means were tabulated. The data were statistically analyzed using Statistical Package for the Social Sciences software utilizing paired t-test; p value was found to be significant for all parameters except distal papilla and symmetry, which showed p = 0.257 and p = 0.110 respectively.

Conclusion

According to the results of this study, esthetic performances of zirconia abutment in implant-supported restorations were determined to be higher than those values associated with titanium abutments.

Preliminary in vivo Investigation into the Relationship between Canal Preparation Protocol and Incidence of Postoperative Pain in Single-visit and Two-visit Endodontic Therapy: A Randomized Controlled Clinical Trial
Authors: Bhagwat Sumita , Sheth Nehal
Published: May 2017

Introduction

Postoperative pain is a major concern for patients undergoing root canal treatment. Much research has gone into the alteration of several variables to determine the elusive technique that will result in no postoperative pain.

Aim

The aim of our study was to investigate the incidence, severity, and duration of postoperative pain in relation to technique of root canal preparation and compare the difference in incidence, severity, and duration of postoperative pain in single- and two-sitting root canal therapy when different instrumentation techniques are used.

Materials and methods

Sixty adult patients requiring root canal therapy were selected and divided into six groups. Singlesitting root canal treatment was carried out in three groups, with three different canal preparation methods (group I – Conventional hand files, group II – hand ProTaper files, and group III – rotary ProTaper files). Two-sitting root canal treatment was carried out in three groups, with the same canal preparation methods (group IV – conventional hand files, group V – hand ProTaper files, and group VI – rotary ProTaper files). Postoperatively, the subjects were instructed to fill out a series of self-report questionnaires for pain incidence after 1 day, 2 days, 3 days, 1 week, and 2 weeks. After 2 weeks, the patients were recalled and their responses were duly noted.

Results

Results were tabulated and statistically analyzed using Mann–Whitney U test.

Conclusion

There was a significant difference in incidence, character, and duration of postoperative pain in rotary-prepared canals as compared with hand-prepared canals in both singleand two-sitting endodontics.

Clinical significance

The purpose of this study was to search for a predictability in incidence, duration, and character of postoperative pain in canals instrumented with hand and rotary instruments. Knowing this will enable clinicians to make more prudent choices in instruments, techniques, and protocols for root canal therapy.

Vulnerability and Local Innovation in Adaptation to Climate Change among the Pastoralists: Harshin District, Somali Region, Ethiopia
Authors: Michael Yohannes Gebre
Published: May 2017

The case study was made with the overall aim of understanding of pastoralist vulnerability and adaptation to climate changes. As a methodology five kebeles have been purposely selected representing pastoral and agro-pastoral farming systems in Harshin district of Somali Region in Ethiopia. The survey was conducted through semi-structured checklists with individual households and groups accounting a total of 124 people.The major findings of the study indicated that the environmental and socio-economic dynamics are skewed to negative trends where the livelihood of the pastoral community is under a big threat. Moreover, the combinations of factors including access to resources and social institutions, livelihood practices, inappropriate technologies and policies have attributed to trigger the vulnerability to climate change among the pastoralists in general and agro-pastoralists in particular. In adapting to the impact of climate change, pastoralists and agro-pastoralists are using wide range of group and individual local innovations, some farming practices and establishment of multi-functional grassroots institutions. Finally creating enabling policy environment for local experimentation and innovations in the framework of pastoralism and sustainability have been suggested as a point of departure in developing resilience to climate change and other pressures.

O meio ambiente do trabalho como nova diretriz constitucional da tutela ambiental: o contraste entre o ideal constitucional e a realidade brasileira
Authors: Silva Junior Antonio Braga da , Farias Paulo Jose Leite
Published: May 2017

O presente trabalho discorrerá acerca do meio ambiente laboral como uma das facetas da unidade ambiental tutelada na Lei Maior. Serão apresentados a contextualização do direito ambiental como direito fundamental de terceira dimensão, sua evolução normativa no ordenamento jurídico nacional e os aspectos gerais de seu conceito. Passando ao enfoque no direito ambiental do trabalho, será abordado o surgimento dessa nova disciplina jurídica, a respectiva conceituação doutrinária e as condições para o alcance de um ambiente de trabalho sadio, de modo a tornar possível explorar a aparente contradição existente no fato de a Constituição da República assegurar o direito fundamental a um ambiente laboral equilibrado e saudável e, ao mesmo tempo, estipular adicionais remuneratórios que admitem a “compra” da saúde, da integridade física e da vida social do trabalhador. Malgrado as evidências deletérias dessa abertura constitucional à mercantilização do direito fundamental à sadia qualidade de vida laboral, vislumbrar-se-á uma defensável função dos adicionais legais remuneratórios: o caráter punitivo e pedagógico como mecanismo adicional de tutela do meio ambiente do trabalho, sem prejuízo do propósito principal de eliminação da nocividade ambiental de que depende a efetividade do direito fundamental a um ambiente do trabalho equilibrado e saudável.

Comparing Renewable Energy Policies in the European Union and Turkey
Authors: Zafir C. Zeynep , Keivanfar Mohammad
Published: May 2017

The European Commission’s policy on “climate change and energy” under the Renewable Energy Directive is an important part of the European Commission policies. As a target, the Commission wants its member countries to increase total energy consumption from renewable energy sources to 20% in the European Union (EU) by 2020. This means, any country which is interested in joining the EU should adhere to its policies and conditions regarding energy consumption. In this paper, firstly, we study the trend of renewable energy consumption in the EU. Data illustrate that the EU region, as a whole, is near its goal, although some members still have to work more or undertake reforms to reach the 20% renewable energy target. Secondly, the renewable energy condition in Turkey, a country that has been preparing in the past decade to join the EU, is surveyed. Based on the results, Turkey needs to pay attention to new renewable resources in order to reach the EU’s target.
The Effect of Perceived Corruption on Entrepreneurial Intention: Evidence from Italy
Authors: Allini Alessandra , Ferri Luca , Maffei Marco , Zampella Annamaria
Published: May 2017

This paper aims to examine the entrepreneurial intention of undergraduate students, using a modified version of Ajzen’s theory of planned behavior (TPB), considering the perception of corruption. We conducted a questionnaire survey with Italian students. There were a total of 350 student participants. In order to analyze the data collected with the questionnaire, structural equation modeling is provided. Our results indicate that the majority of students have strong entrepreneurial intention but due to the effect of corruption students are dissuaded from engaging in entrepreneurship. Corruption has a negative effect on students’ entrepreneurial behavior. This paper provides a new model that helps to understand the students’ entrepreneurial intentions considering the corruption perception.
