Le travail tringulaire en Grece: Certains cas de travail tringulaire dans la fonction publique
Authors: Petraki Georgia 
Published: December 2016

<p>Our work hypothesis is that the hegemonic employment model in Greece, which safeguarded employment and strong legal protection for the majority of employees, is in a process of transformation to the opposite direction. In the special conditions created by the policies of internal devaluation under the supervision of the troika, work relations are in a process of change in both the private and the public sector: The institutional protection of employment is “freezing”, and its place is occupied by special regimes, created through the application laws following the successive memoranda imposed by the governments of the last few years. Thus, the employment model tending to generalise in Greece at present, i.e. work with little or no institutional rights, was already in existence during the previous period, but concerned a small part of the active population. The consequence of the abolition of fundamental work rights, is the renewal of the larger part of wage labour through precarious work regimes. </p>

AimsThe role of high tibial osteotomy (HTO) is being questioned by the use of unicompartmental knee arthroplasty (UKA) in the treatment of medial compartment femorotibial osteoarthritis. Our aim was to compare the outcomes of revision HTO or UKA to a total knee arthroplasty (TKA) using computer-assisted surgery in matched groups of patients.Patients and MethodsWe conducted a retrospective study to compare the clinical and radiological outcome of patients who underwent revision of a HTO to a TKA (group 1) with those who underwent revision of a medial UKA to a TKA (group 2). All revision procedures were performed using computer-assisted surgery. We extracted these groups of patients from our database. They were matched by age, gender, body mass index, follow-up and pre-operative functional score. The outcomes included the Knee Society Scores (KSS), radiological outcomes and the rate of further revision.ResultsThere were 20 knees in 20 patients in each group. The mean follow-up was 4.1 years (2 to 18.7). The mean total KSS at last follow-up was 185.7 (standard deviation (sd) 5) in group 1 compared with 176.5 (sd 11) for group 2 (p = 0.003). The mean hip-knee-ankle angle was 180.2° (sd 3.2°) in group 1 and 179.0° (sd 2.2°) in group 2. No revision was required.ConclusionWe found that good functional and radiological outcomes followed revision of both HTO and UKA to TKA. Revision of HTO showed significantly better functional outcomes. These results need to be further investigated by a prospective randomised controlled trial involving a larger group of patients.

Published: December 2016

AimsTo determine the normal values and usefulness of the C1/4 space available for spinal cord (SAC) ratio and C1 inclination angle, which are new radiological parameters for assessing atlantoaxial instability in children with Down syndrome.Patients and MethodsWe recruited 272 children with Down syndrome (including 14 who underwent surgical treatment), and 141 children in the control group. All were aged between two and 11 years. The C1/4 SAC ratio, C1 inclination angle, atlas-dens interval (ADI), and SAC were measured in those with Down syndrome, and the C1/4 SAC ratio and C1 inclination angle were measured in the control group.ResultsThe mean C1/4 SAC ratio in those requiring surgery with Down syndrome, those with Down syndrome not requiring surgery and controls were 0.63 (standard deviation (sd) 0.1), 1.15 (sd 0.13) and 1.29 (sd 0.14), respectively, and the mean C1 inclination angles were -3.1° (sd 10.7°), 15.8° (sd 7.3) and 17.2° (sd 7.3), in these three groups, respectively. The mean ADI and SAC in those with Down syndrome requiring surgery and those with Down syndrome not requiring surgery were 9.8 mm (sd 2.8) and 4.3 mm (sd 1.0), and 11.1 mm (sd 2.6) and 18.5 mm (sd 2.4), respectively.ConclusionThe normal values of the C1/4 SAC ratio and the C1 inclination angle were found to be about 1.2° and 15º, respectively.

Impact of a learning curve on the survivorship of 4802 cementless total hip arthroplasties
Authors: Magill P. , Blaney J. , Hill J. C. , Bonnin M. P. , Beverland D. E. 
Published: December 2016

Aims Our aim was to report survivorship data and lessons learned with the Corail/Pinnacle cementless total hip arthroplasty (THA) system. Patients and Methods Between August 2005 and March 2015, a total of 4802 primary cementless Corail/Pinnacle THAs were performed in 4309 patients. In March 2016, we reviewed these hips from a prospectively maintained database. Results A total of 80 hips (1.67%) have been revised which is equivalent to a cumulative risk of revision of 2.5% at ten years. The rate of revision was not significantly higher in patients aged ≥ 70 years (p = 0.93). The leading indications for revision were instability (n = 22, 0.46%), infection (n = 20, 0.42%), aseptic femoral loosening (n = 15, 0.31%) and femoral fracture (n = 6, 0.12%). There were changes in the surgical technique with respect to the Corail femoral component during the ten-year period involving a change to collared components and a trend towards larger size. These resulted in a decrease in the rate of iatrogenic femoral fracture and a decrease in the rate of aseptic loosening. Conclusion The rate of revision in this series is comparable with the best performing THAs in registry data. Most revisions were not directly related to the implants. Despite extensive previous experience with cemented femoral components, the senior author noted a learning curve requiring increased focus on primary stability. The number of revisions related to the femoral component is reducing. Any new technology has a learning curve that may be independent of surgical experience.

College Peer Mentoring and Students With Intellectual Disability: Mentors' Perspectives on Relationship Dynamics
Authors: Culnane Mary , Eisenman Laura T. , Murphy Aideen 
Published: December 2016

Abstract
College programs for students with intellectual disability frequently engage peer mentors to promote students' social connections on campus. The qualitative study discussed in this article was conducted to explore, from mentors' perspectives, how mentor/mentee relationships developed, how mentors offered supports, and how mentors facilitated membership into the campus community. Using Pawson's (2004) conceptual framework, mentoring relationships were analyzed in regard to status, reference group, and mentoring mechanisms. Mentors perceived themselves as well-positioned to facilitate their partners becoming college insiders. They used coaching and direction setting to support mentees, and identified factors that appeared to facilitate or hinder shifts in mentee status, including their own beliefs and skills, role conflicts, and person-centered thinking. Implications for supporting peer mentors and refining program theory are also discussed.

Bemühungen um ein Bibliotheksgesetz für Niedersachsen
Authors: Haas Lothar 
Published: December 2016

Zusammenfassung
Der Beitrag beschreibt das mühsame Agieren zweier Organisationen der Zivilgesellschaft für ein Bibliotheksgesetz. Der Erfolg ist noch nicht da, aber auch nicht ausgeschlossen. Die Verbände versuchen, Landtagsfraktionen, Abgeordnete und Landesregierung zu bewegen, sich zugunsten eines Bibliotheksgesetzes zu entscheiden. Als sie nicht weiterkommen, legen sie selbst einen ausgearbeiteten Entwurf mit Begründung vor. Die Kontakte mit Abgeordneten werden von der Frage bestimmt, ob ein Kulturfördergesetz einem Bibliotheksgesetz vorzuziehen ist. Die Abgeordneten fragen schließlich, ob sich die bereits bestehenden Bibliotheksgesetze als praktisch wirksam erwiesen hätten. Die Frage kann, vor allem mit Blick auf das Gesetzgebungsverfahren zur Verlängerung des Hessischen Bibliotheksgesetzes, positiv beantwortet werden. Die politische Folgerung für Niedersachsen steht noch aus.
StegHash: New Method for Information Hiding in Open Social Networks
Authors: Szczypiorski Krzysztof 
Published: December 2016

Abstract
In this paper a new method for information hiding in open social networks is introduced. The method, called StegHash, is based on the use of hashtags in various open social networks to connect multimedia files (like images, movies, songs) with embedded hidden messages. The evaluation of the system was performed on two social media services (Twitter and Instagram) with a simple environment as a proof of concept. The experiments proved that the initial idea was correct, thus the proposed system could create a completely new area of threats in social networks.
Utilization Balancing Algorithms for Dynamic Multicast Scheduling Problem in EON
Authors: Markowski Marcin 
Published: December 2016

Abstract
Dynamic data transfer demands are often being a challenge for present communication networks, as they appear in unpredictable time and must be satisfied prior to deadline. Important kind are the multi-target demands occurring in task of replication, backup, database synchronization or file transferring in pear-to-pear networks. Optimal scheduling usually depends of the nature of transport network. In the paper dynamic deadline-driven multicast scheduling problem over elastic optical network is considered. Particularly, the method for improving link utilization by traffic balance for multicast demands is proposed. Few heuristic algorithms and results of experiments, proving the benefits of balancing concept are presented
Quadrature Mapping, Saleh’s Representation, and Memory Models
Authors: Borys Andrzej 
Published: December 2016

Abstract
In the literature, Saleh’s description of the AM/AM and AM/PM conversions occurring in communication power amplifiers (PAs) is classified as a representation without memory. We show here that this view must be revised. The need for such revision follows from the fact that the Saleh’s representation is based on the quadrature mapping which, as we show here, can be expanded in a Volterra series different from an usual Taylor series. That is the resulting Volterra series possesses the nonlinear impulse responses in form of sums of ordinary functions and multidimensional Dirac impulses multiplied by coefficients being real numbers. This property can be also expressed, equivalently, by saying that the nonlinear transfer functions associated with the aforementioned Volterra series are complex-valued functions. In conclusion, the above means that the Saleh’s representation incorporates memory effects.

Published: December 2016

ZusammenfassungSowohl in der Wirtschaft als auch in der Wissenschaft spielen Projekte und Projektmanagement eine zunehmende Rolle. Projekte beeinflussen immer häufiger die Arbeitsstrukturen in Organisationen und wissenschaftlichen Instituten. Sie ermöglichen dynamisches, flexibles und vernetztes arbeiten, was in der heutigen Welt gefragt ist. Projektbasierte Arbeit bringt jedoch auch unterschiedliche Herausforderungen mit sich. Besonders im Falle von komplexen Projektkonstellationen, an denen Spezialisten aus verschiedenen Fachrichtungen und Ländern beteiligt sind, können strukturelle, sprachliche und kulturelle Hürden sehr groß sein. Der Artikel stellt theoretische Überlegungen zu der von der Forschung bislang vernachlässigten Beziehungsebene in der interkulturellen Projektkommunikation an und analysiert die Rolle von Asymmetrien für die projektinterne Kommunikation anhand von E-Mail-Interaktionen aus Wissenschafts- und Wirtschaftsprojekten.
Zur Verschriftung mündlich tradierter Sprachen in sozialen Netzwerken: Der Gebrauch des Tarifit auf Facebook
Authors: Tahiri Naima 
Published: December 2016

AbstractIt isn’t particularly difficult to use one’s own language in computer-mediated communication, when the language has a written culture. However, the situation is different, when the language is only an orally transmitted language and one wants to use it for communication in New Media. There is a lack of unified rules, to which one can orientate oneself. The native speakers of Tarifit, who want to use their language in computer-mediated communication as well (like in Facebook groups), are in such a situation. There are many Facebook groups of Rifian Berbers, but the communication within these groups is usually not only in Tarifit. In groups with cultural topics on the other hand, a dominance of Tarifit can be observed. This includes groups, which have been created specifically for the culturally typical rhyme-songs of the Rif, the so-called “izran”.The analysed corpus of the present study originates from such a group. The initiated standardization processes for Berber in Morocco have not had any impact on the language use in social networks yet. The Berber script Tifinagh, introduced in Morocco’s education system in 2003, has never been used for communication between group members. The Arabic script is rarely used. This behavior can have different reasons, which are discussed below. It can be observed, that the Latin writing system is often chosen for the notation of Tarifit. Instead of using diacritics, the Latin characters are complemented by Arabic numerals when certain sounds have no corresponding graphemes. The choice of the writing system requires a constant assignment of graphemes to the sounds, but the notations are often characterized by the absence of uniform spelling and by neutralisations between phonemes.

Published: December 2016

AbstractHexagonal Zn1–xCdxO microtubes with CdO contents (x = 0, 1, 3 and 5 %) have been successfully synthesized via direct microwave irradiation. Field emission scanning electron microscopy (FE-SEM), UV–vis spectroscopy, photoluminescence (PL), and energy-dispersive spectrometer (EDS) were employed to characterize the Zn1–xCdxO microtubes. Zn1–xCdxO microtubes have an average diameter of 140 µm, wall thickness of 2~4 µm and length of about 250 µm. UV–vis studies showed that the optical band gap of ZnO microtube (3.27 eV) was reduced to 3.20 eV for Zn0.97Cd0.03O microtube. The PL spectra showed a strong emission peak in the visible region centered at 562.88 nm with a weak UV emission has been detected for Zn0.97Cd0.03O microtube. EDS confirms the presence of Zn and O in ZnO microtube and the absence of Cd as a doping material for CdO-doped ZnO microtubes due to the small amounts of CdO concentration.

Published: December 2016

Abstract
The work describes the impact the reliability of the information quality IQ for information and communication systems. One of the components of IQ is the reliability properties such as relativity, accuracy, timeliness, completeness, consistency, adequacy, accessibility, credibility, congruence. Each of these components of IQ is independent and to properly estimate the value of IQ, use one of the methods of modeling uncertainty. In this article, we used a hybrid method that has been developed jointly by one of the authors. This method is based on the mathematical theory of evidence know as Dempstera-Shafera (DS) theory and serial links of dependent hybrid named IQ (hyb).

Published: December 2016

Abstract
This article introduces division of transport systems into land transport systems (road and rail) as well as land and water transport systems (inland and sea), depending on the type of environment in which these systems carry out their tasks. Such systems comprise the class of social engineering systems of the Man – Technological Object – Environment (M – TO – E) type. Such systems are influenced by forcing factors, leading to changes in their condition. Such factors may be divided into operational, external and anthropotechnical and they cause the degradation of the system on various levels, including a decrease of the degree of its safety. The article attempts to evaluate the safety of the operation of transport systems on the basis of the evaluation of the safety of the transport process carried out over a defined time interval Δt. The evaluation of the safety of the implemented transport process was prepared on the basis of a set of calculated index values determined depending on the type of transport.

Abstract
This investigation was carried out in the frames of the Interreg 4A project “Workability and Social Inclusion” headed by the Arcada University of Applied Life. Tallinn University of Technology and Rīga Stradiņš University were involved in the project. A questionnaire based on the Nordic, WAI (Work Ability Index), and Kiva questionnaires was compiled to study psychosocial and physical working conditions at computer-equipped workplaces for 192 workers. The results showed that the computer workers assess their health status considerably high. They are optimistic in solving the problem that the monotonous work with computers will continue and believe that their health status in the future will stay at the same level using the steadily enhancing rehabilitation means. The most injured regions of the body were the right wrist and the neck. The novelty of the study consists in the graphical co-analysis of different groups of questions presented to the workers, which allows to assess the physiological and psychological factors in complex. The rehabilitation means have to be developed and the possibility for rehabilitation must be made available to the greatest possible number of workers. The workers were divided into two groups: Group A, the length of employment with computers under 10 years (included) and Group B, having been working with computers over 10 years. These groups were found to differ in the perception of psychosocial risk factors at the workplace. Group B assessments for psychosocial working conditions were better than those of group A. In group B, employees appeared to be more afraid of losing their jobs and therefore they were not so demanding for the work atmosphere as in group A.
Improvement of Workplace Ergonomics in Atrium-Type Buildings

Published: December 2016

Abstract
The aim of the study was to improve the indoor quality and ergonomics of workplaces in atrium-type buildings. The investigated atrium-type building has the atrium (15×30 metres) inside. The roof of the atrium is built from glass and there is a break between the walls and the roof. It gives the possibility for workers in rooms closed to the atrium to have some fresh air. Nevertheless, there are problems caused by shortage of natural light, high concentrations of CO2 and low room temperature in winter. The main results of the investigation were: the design of the workplaces needs to be carried out in parallel to the construction of the building; later it is difficult to improve conditions in the workplace; the air temperature in workrooms depends on the room location in the building and in winter, rooms closed to the atrium are cold; the concentration of CO2 exceed limits in rooms where windows cannot be opened. Workers are endangered by developing sick building syndrome. The concentration of dust is under the limits, but the problem of dusty air was raised by the workers. Some ergonomic improvements are possible and corresponding recommendations were given to the employers.
Politiques de la sémiotique: Flux et reflux de la critique idéologique chez A. J. Greimas
Authors: Provenzano François 
Published: December 2016

RésuméL’article part d’un contraste entre deux articles de circonstance signés par Greimas en 1956 pour l’un (« Pour une sociologie du langage »), en 1980 pour l’autre (« Roland Barthes : une biographie à construire »), en montrant la modulation qu’y subissent les topiques d’un substrat marxiste du projet scientifique de la sémiotique : la conciliation entre science et idéologie et de la fonction sociale de l’intellectuel. Ces topiques sont ensuite déclinées au fil de la lecture d’autres travaux du tournant des années 1960-1970, relativement périphériques par rapport au canon de la théorie greimassienne. En témoignant d’un dialogue de la sémiotique avec ses marges disciplinaires (l’histoire, l’ethnologie, la sociolinguistique), ces travaux manifestent un ancrage fort de la réflexion de Greimas dans le terreau d’une critique idéologique historiquement située.
