Authors: Pidaparti Ramana , Kalaga Sriram 
Published: October 2017

Background:
The structural performance of cross arms used on distribution poles is studied in this paper. Tangent and Dead End configurations involving conventional (wood) and composite (fiber glass) cross arms are analyzed. Strength-to-Stiffness and Weight-to-Stiffness ratios associated with study cases are determined and evaluated.

Results and Conclusion:
It is observed that although initial costs are higher, composite cross arms offer long-term advantages in terms of strength, stiffness, performance and durability.

Published: October 2017

Introduction:
This study aimed to compare the effectiveness of two activated irrigation techniques in removing the smear layer after single-file reciprocating instrumentation in curved canals.

Materials and Methods:
Sixty distobuccal roots of maxillary molars were standardized to create a closed system, and then instrumented using WaveOne Primary (Dentsply Maillefer, Ballaigues, Switzerland) instruments. Fifty-four specimens were randomly distributed into 3 groups for final irrigation: Non-activated irrigation, passive ultrasonic irrigation (PUI), and EndoActivator (EA;Dentsply Maillefer, Tulsa, USA) irrigation. All specimens received 3 mL of 17% EDTA for 1 minute, followed by irrigation with 6 mL of 2.5% NaOCl. The apical, middle and cervical thirds of the specimens were analyzed using scanning electronic microscopy (SEM), and the amount of remaining smear layer on the canal walls was rated by three examiners using a five-category scoring system. Kendall’s concordance coefficient was used to assess inter-rater agreement. Kruskal-Wallis and Mann-Whitney (Bonferroni) tests were used to compare the scores.

Results:
Kendall’s concordance coefficient was ≥ 0.7, indicating an excellent level of agreement between the raters. No statistically significant difference in irrigation techniques efficacy for removal of the smear layer (p=0.061) was found for the apical third. The scores attributed to the specimens irrigated with the EA system were significantly lower than those of the other groups in the cervical and middle thirds (p< 0.05).

Conclusions:
The efficacy of the EA system in removing the smear layer in the cervical and middle thirds of root canals instrumented with reciprocating motion was significantly higher than that of either PUI or non-activated irrigation. Both EA and PUI performed similarly in apical third.
Bayesian Inference for Three Bivariate Beta Binomial Models
Authors: Scollnik David Peter Michael 
Published: October 2017

Background:This paper considers three two-dimensional beta binomial models previously introduced in the literature. These were proposed as candidate models for modelling forms of correlated and overdispersed bivariate count data. However, the first model has a complicated form of bivariate probability mass function involving a generalized hypergeometric function and the remaining two do not have closed forms of probability mass functions and are not amenable to analysis using maximum likelihood. This limited their applicability.Objective:In this paper, we will discuss how the Bayesian analyses of these models may go forward using Markov chain Monte Carlo and data augmentation.Results:An illustrative example having to do with student achievement in two related university courses is included. Posterior and posterior predictive inferences and predictive information criteria are discussed.

Authors: Lachmar E Megan , Wittenborn Andrea K , Bogen Katherine W , McCauley Heather L 
Published: October 2017

Background
Social media provides a context for billions of users to connect, express sentiments, and provide in-the-moment status updates. Because Twitter users tend to tweet emotional updates from daily life, the platform provides unique insights into experiences of mental health problems. Depression is not only one of the most prevalent health conditions but also carries a social stigma. Yet, opening up about one’s depression and seeking social support may provide relief from symptoms.

Objective
The aim of this study was to examine the public discourse of the trending hashtag #MyDepressionLooksLike to look more closely at how users talk about their depressive symptoms on Twitter.

Methods
We captured 3225 original content tweets for the hashtag #MyDepressionLooksLike that circulated in May of 2016. Eliminating public service announcements, spam, and tweets with links to pictures or videos resulted in a total of 1978 tweets. Using qualitative content analysis, we coded the tweets to detect themes.

Results
The content analysis revealed seven themes: dysfunctional thoughts, lifestyle challenges, social struggles, hiding behind a mask, apathy and sadness, suicidal thoughts and behaviors, and seeking relief.

Conclusions
The themes revealed important information about the content of the public messages that people share about depression on Twitter. More research is needed to understand the effects of the hashtag on increasing social support for users and reducing social stigma related to depression.

In hospital environments, there are several problems related to Healthcare-Associated Infections (HAIs), contaminated hospital textiles, can contribute to the spread and transmission of (HAIs), due to retention of viruses and bacteria. The antibacterial metallic nanoparticles immersed in hospital textiles can allow reduction of microorganisms. This paper presents a technological surveillance of the principal properties of antibacterial nanotextiles to be used in hospital environments, based on international standards. Initially, the search equation was determined for “antibacterial” AND “nanoparticle.” Subsequently, the main properties were selected, by means of a multiple authors’ review. Afterwards, the properties were related to international standards. Finally, we present the results found associated to the materials used to develop nonwoven textiles, and their properties for hospital environments, the sizes of samples and also the equipment required for characterization.

L’Educational Turn. L’éducation comme média artistique: À la recherche d’une interactivité nouvelle
Authors: Lemay-Perreault Rébéca 
Published: October 2017

Abstract: “Educational Turn”, an expression used for a decade by museology and various contemporary art environments, by artists as well as curators (Rogoff, 2008; O’Neill & Wilson (Eds.), 2010; Wilson & O’Neill, 2010; Wesseling (Ed.), 2011). Derived from artistic avant-garde tendencies of the second half of the 20th Century, including institutional critique and relational aesthetics, it immediately brings forward the issues of interactive modalities of the exhibited artwork, public participation, and knowledge dissemination. But this expression actually goes further since the concept of “educational turn” is not only rooted in the artwork as a mediation tool, but to cite Podesva (2007), in education as an artistic medium, fudging the disciplinary limits of art, museology, and museum education. What is new about this turn and how does it transform museum practices? This essay aims to define a new interaction mode embodied by these productions by analyzing the historiographical corpus theorizing the movement. KEYWORDS: Educational Turn; contemporary art; interactivity; museum; postmodernismRésumé: « Educational turn », un terme qui, depuis dix ans, a su se faire connaître dans différents milieux de l’art contemporain et de la muséologie, tant chez les artistes que chez les conservateurs (Rogoff, 2008; O’Neill & Wilson (Eds.), 2010; Wilson & O’Neill, 2010; Wesseling (Ed.), 2011). Issu des avant-gardes artistiques de la deuxième moitié du 20e siècle, notamment de la critique institutionnelle et de l’esthétique relationnelle, il pose d’emblée la question des modalités d’interactivité de l’objet d’exposition, de la participation des publics et de la transmission des savoirs. Mais l’expression va plus loin puisque l’idée d’un « educational turn » prend non seulement ancrage dans une conception de l’œuvre d’art comme dispositif de médiation, mais aussi, pour reprendre l’expression de Podesva (2007), de l’éducation comme un médium artistique, brouillant les frontières disciplinaires de l’art, de la muséologie et de l’éducation muséale. En quoi ce tournant est-il nouveau et quelles transformations apporte-il à la pratique muséale ? À travers une analyse du corpus historiographique théorisant le mouvement, cet essai vise définir un nouveau mode d’interactivité incarné dans ces productions.MOTS CLES: Eductional Turn; art contemporain; interactivité; musée; postmodernité

Published: October 2017

SummaryAim: To assess whether clinical prostate cancer (PCA) related factors and therapy status can predict the degree of tracer uptake on [68Ga]PSMA-HBED-CC PET/CT.Materials & methods: We retrospectively studied 124 patients with recurrent an/or metastatic PCA who underwent [68Ga]PSMAHBED-CC PET/CT. The maximum standardized uptake value (SUVmax) was determined in the prostate bed as well as in three size categories (≤ 5 mm, > 5–15 mm, > 15 mm) in pelvic lymph node, extrapelvic lymph node, bone and visceral metastases.Results: Significant positive correlations between lesion size and SUVmax were found in pelvic lymph node metastases > 5 -≤15 mm (Spearmans rho = 0.502, p = 0.002) as well as in extrapelvic lymph node metastases5 mm (rho = 0.314, p = 0.033) and > 5 ≤-15 mm (rho = 0.614, p < 0.001). SUVmax tended to be higher in the largest diameter category in each anatomic station than in the middle and lower categories. We were unable to find evidence for a relationship between SUVmax and PSA, PSAdt, Gleason score, androgen deprivation therapy, radiation therapy or chemotherapy status.Conclusion: Measured tracer uptake in [68Ga]PSMA-HBED-CC PET/CT in patients with recurrent/metastasized prostate cancer is significantly influenced by lesion size as a result of partial volume effects in the very small lesions. Clinical indicators of aggressive prostate cancer behaviour such as PSA levels, PSA doubling time or the Gleason score of the primary tumour, as well as the androgen deprivation therapy, radiation therapy or chemotherapy status are not related to measured tracer uptake.
La France et ses « siècles de plomb »
Authors: Ferragu Gilles 
Published: October 2017

Le terrorisme serait-il une invention française ? En suivant, depuis la fin du X VIII e siècle, l’émergence de ce phénomène et sa récurrence dans l’histoire française, on peut tout à la fois en esquisser une première généalogie, mais aussi saisir l’ampleur de son influence sur l’histoire politique nationale. Bien loin d’être une violence « extraordinaire », il apparaît que le terrorisme, sous ses diverses acceptions, hante l’histoire contemporaine et s’inscrit dans une autre histoire de la modernité politique.
