Authors: Ritonga Imelda L 
Published: July 2018

Introduction. Previous studies have found that severe stress can occur in nursing students because of their education system; however there have not been any studies to address stress in nursing students, conducted in Indonesian. The studies reinforce that stress in nursing students, is an important factor for nursing lecturers to consider in nursing education. Students felt helpless when they could not change situations they did not like and complained that the learning approach was authoritarian. This study identifi ed stressors in nursing students and effect of stress in the students’ learning process. Method. A case study was used with cognitive appraisal theory from Lazarus and Folkman (1984), as the theoretical proposition. Data was collected by utilizing in-depth interviews with nursing students. Results. There were fi ve evident themes found in this study related to stress and its effect on the students’ learning process. These Themes were: (1). Dormitory living, (2). Learning in the school, (3). Learning in the clinical setting, (4). Personal and socialbeliefs, and (5). Short-term and long-term effects. Discussion. Results indicated that education process used in this particular school of nursing, created stress which impacted adversely on the students’ learning process. Some of the problems identifi ed are specific to nursing education in Indonesian.Keywords: psychological stress, stressor, cognitive appraisal, coping

A unified rule to estimate multiaxial elastoplastic notch stresses and strains under in-phase proportional loadings
Authors: Meggiolaro Marco Antonio , Tupiassú Pinho de Castro Jaime , Martha Luiz Fernando , Nazaré Marques Luiz Fernando 
Published: July 2018

Several methods can be used to estimate elastoplastic (EP) notchtip stresses and strains from linear elastic calculations, providing EP stress and strain concentration factors. For uniaxial load histories, Neuber’s and Glinka’s rules are perhaps the most used. For non-proportional multiaxial histories, such corrections require incremental plasticity calculations to correlate stresses and strains at the notch root, a quite challenging task. However, for in-phase proportional multiaxial histories, where the principal directions do not change and the load path in a stress diagram follows a straight line, approximate methods can be used without requiring an incremental approach. Most of these methods are based on Neuber’s rule, so they usually result in conservative predictions, especially in plane strain-dominated cases associated with sharp notches. In this work, a Unified Notch Rule (UNR) is proposed for uniaxial and in-phase proportional multiaxial histories. The UNR can reproduce Neuber’s or Glinka’s rules, interpolate their notch-tip behaviors, or even extrapolate them for notches with increased constraint. Moreover, the UNR also allows a non-zero normal stress perpendicular to the free-surface. The proposed method predictions are compared with elastoplastic Finite Element calculations on notched shafts.
Reflexões sobre a construção de outro paradigma na engenharia: potencialidades e limitações das tecnologias sociais e da extensão universitária
Authors: Chaves Vitor Tonzar , Pérez Pompeu Lucca 
Published: July 2018

O presente artigo tem como objetivo principal discutir como o marco analítico conceitual da Tecnologia Social (TS) e a Extensão Universitária (EU) podem contribuir para a ressignificação da engenharia. Para nortear essa reflexão adota-se o conceito de paradigma a fim de integrar os diferentes fatores sociotécnicos que condicionam a formação e atuação dos engenheiros. Seguimos com a caracterização do paradigma tradicional da engenharia, buscando identificar como as contribuições da TS e da EU podem transformá-lo. Realizamos uma revisão crítica desses conceitos e apresentamos como estudo de caso a experiência de um grupo de extensão que nós participamos. Essa experiência ajudou a refletir sobre as potencialidades e limitações da EU e da TS para a construção desse outro paradigma na engenharia e nos levaram a concluir que elas são importantes ferramentas nesse processo, pois a EU contribui para materialização da TS a partir da prática assentada em outros valores. Mas concluímos que uma transição paradigmática só será alcançada em um processo mais amplo de disputa política, pois a EU e a TS em si não garantem a transformação dos paradigmas dos cursos de engenharia.
Radioscopie de l'information télévisée au Canada
Authors: Monière Denis , Fortier Julie 
Published: July 2018

Les différents diffuseurs offrent à leurs auditoires respectifs ni tout à fait la même information, ni le même traitement de l'actualité. En tenant compte de variables qu'on peut mesurer, comme le temps de parole accordé aux acteurs politiques ou le temps consacré par chaque chaîne aux nouvelles communes, Denis Monière et Julie Fortier montrent, chiffres à l'appui, que le journalisme canadien obéit, comme on s'y attendait, à des règles différentes selon le public auquel il s'adresse. Ils montrent aussi cependant que l'information est moins tributaire qu'on pourrait le croire des mandats officiels : ce n'est pas tant le statut public ou privé d'une chaîne qui importe en ce cas, que sa langue de diffusion.
Sports Bettors: A Systematic Review
Authors: Mercier Jonathan , Sévigny Serge , Jacques Christian , Goulet Annie , Cantinotti Michael , Giroux Isabelle 
Published: July 2018

Sports betting is associated with problematic gambling behaviours. However, little is known about the profile of sports bettors. Also, it is still unclear if there are useful abilities in sports betting. This systematic review aims to describe gambling habits and cognitions of sports bettors, and determine the roles of chance and skill in sports betting. Addressing the chance and skill distinction in sports betting would be helpful to identify which of sports bettors' cognitions are erroneous. Out of 991 studies identified in the databanks, 31 met the inclusion criteria of this review. Results indicate that these studies are mostly conducted with male samples aged from 30 to 50 years. These gamblers bet many times per week, with weekly averages ranging from 100 to 200$ CAD. Five studies examined the roles of chance and skill in sports betting, among which three showed that sports bettors perform better than chance in predicting results accurately, but they do not win more money than they would with a random selection, due to the structure of the game. The 11 studies that focused on cognitions indicate that sports bettors overestimate the influence of skill on the outcome of the game. These results support the need to further study the role of cognitions in the behaviours of sports bettors. It also offers insights concerning the distinction between chance and skill in sports betting.RésuméLes paris sportifs sont associés à des comportements de jeu problématiques. Cependant, on sait peu de choses sur le profil des parieurs sportifs. De plus, il est difficile de statuer si certaines habiletés seraient utiles dans les paris sportifs. Cette revue systématique vise à décrire les habitudes de jeu, les cognitions des parieurs sportifs, et à déterminer le rôle du hasard et des habiletés dans ces paris. Examiner la distinction entre le hasard et les habiletés aux paris sportifs serait utile afin de déterminer quelles cognitions entretenues par les parieurs sportifs sont erronées . Sur 991 études repérées dans les banques de données, 31 répondaient aux critères d’inclusion de cette revue. Les résultats indiquent que ces études sont principalement menées auprès d’échantillons masculins âgés de 30 à 50 ans. Ces joueurs parient plusieurs fois par semaine et misent en moyenne de 100 $ à 200 $ CA par semaine. Cinq études ont examiné les rôles du hasard et des habiletés dans les paris sportifs, parmi lesquels trois ont montré que les parieurs sportifs prédisent mieux les résultats sportifs que le hasard, mais ils ne gagnent pas plus d’argent qu’avec une sélection aléatoire, en raison de la structure du jeu. Les onze études portant sur les cognitions indiquent que les parieurs sportifs surestiment l’influence des habiletés sur l’issue du jeu. Ces résultats confirment la nécessité d’approfondir le rôle des cognitions dans les comportements des parieurs sportifs. Ils donnent également des pistes sur la distinction entre le hasard et les habiletés dans les paris sportifs.

Abstract. Southern West Africa (SWA) is undergoing rapid and significant socioeconomic changes associated with a massive increase in air pollution. Still, the impact of atmospheric pollutants, in particular that of aerosol particles, on weather and climate in this region is virtually unexplored. In this study, the regional-scale model framework COSMO-ART is applied to SWA for a summer monsoon process study on 2–3 July 2016 to assess the aerosol direct and indirect effect on clouds and atmospheric dynamics. The modeling study is supported by observational data obtained during the extensive field campaign of the project DACCIWA (Dynamics–Aerosol–Chemistry–Cloud Interactions in West Africa) in June–July 2016. As indicated in previous studies, a coastal front is observed that develops during daytime and propagates inland in the evening (Atlantic inflow). Increasing the aerosol amount in COSMO-ART leads to reduced propagation velocities with frontal displacements of 10–30 km and a weakening of the nocturnal low-level jet. This is related to a subtle balance of processes related to the decrease in near-surface heating: (1) flow deceleration due to reduced land–sea temperature contrast and thus local pressure gradient, (2) reduced turbulence favoring frontal advance inland and (3) delayed stratus-to-cumulus transition of 1–2 h via a later onset of the convective boundary layer. The spatial shift of the Atlantic inflow and the temporal shift of the stratus-to-cumulus transition are synergized in a new conceptual model. We hypothesize a negative feedback of the stratus-to-cumulus transition on the Atlantic inflow with increased aerosol. The results exhibit radiation as the key player governing the aerosol affects on SWA atmospheric dynamics via the aerosol direct effect and the Twomey effect, whereas impacts on precipitation are small.
Description of a coastal impact event in Basque Country: the 9 February 2016 case
Authors: Gaztelumendi Santiago , Egaña Joseba , Liria Pedro , Aranda José A. 
Published: July 2018

Abstract. In this work we analysed a case from 9 February 2016 from two points of view,
the meteorological–ocean characteristics of the event and the damage produced during
the episode in the Basque coastal area. On 7 and 8 February 2016
an intense zonal circulation was established in the Atlantic, with very strong
westerly winds (over 100 km h−1) and high fetch (more than 2000 km). As a
consequence a strong swell (over 7 m) arrived on the Basque coast affecting
littoral areas. The wave characteristics are particularly energetic during
the morning of the 9 February, which had a significant wave of 9.5 m and a peak period of
20 s in deep water (Donostia buoy). The arrival of these energetic waves
coincides with high tide during spring when the sea level reaches 4.69 m in the Port of Bilbao. Overtopping indexes exceeded red-level thresholds established
within the Euskalmet coastal warning system and the wave impact resulted in
relevant damage (more than EUR 3 million) in different littoral
areas. This event is the first red-level case since the new Euskalmet warning
procedure became operational at the beginning of 2015.
