Dairy, as a major component of a high protein diet, is a critical dietary source of branched chain amino acids (BCAA), which are biomarkers of health and diseases. While BCAA are known to be key stimulators of protein synthesis, elevated circulatory BCAA is an independent risk factor for type 2 diabetes mellitus. This study examined the impact of altered dairy intake on plasma BCAA and their potential relationship to insulin sensitivity. Healthy adults (n = 102) were randomized to receive dietary advice to reduce, maintain, or increase habitual dairy intake for 1 month. Food intake was recorded with food frequency questionnaires. Self-reported protein intake from dairy was reported to be reduced (−14.6 ± 3.0 g/day), maintained (−4.0 ± 2.0 g/day) or increased (+13.8 ± 4.1 g/day) according to group allocation. No significant alterations in circulating free amino acids (AA), including BCAA, were measured. Insulin sensitivity, as assessed by homeostatic model assessment-insulin resistance (HOMA-IR), was also unaltered. A significant change in dairy protein intake showed no significant effect on fasting circulatory BCAA and insulin sensitivity in healthy populations.

Published: October 2018

Choline, an essential dietary nutrient for humans, is required for the synthesis of the neurotransmitter, acetylcholine, the methyl group donor, betaine, and phospholipids; and therefore, choline is involved in a broad range of critical physiological functions across all stages of the life cycle. The current dietary recommendations for choline have been established as Adequate Intakes (AIs) for total choline; however, dietary choline is present in multiple different forms that are both water-soluble (e.g., free choline, phosphocholine, and glycerophosphocholine) and lipid-soluble (e.g., phosphatidylcholine and sphingomyelin). Interestingly, the different dietary choline forms consumed during infancy differ from those in adulthood. This can be explained by the primary food source, where the majority of choline present in human milk is in the water-soluble form, versus lipid-soluble forms for foods consumed later on. This review summarizes the current knowledge on dietary recommendations and assessment methods, and dietary choline intake from food sources across the life cycle.

Authors: Lassen Anne D. , Knuthsen Pia , Bysted Anette , Andersen Elisabeth W.
Published: October 2018

Monitoring the nutritional environment is important to help inform future initiatives to improve access to healthy foods. The objective was to examine the nutritional quality of lunch meals eaten at 15 worksite canteens and then to compare with results from a study conducted 10 years before. The duplicate-portion-technique with subsequent chemical analysis was used to quantify 240 customers’ lunch intake. Estimated mean energy intake was 2.1 MJ/meal (95% confidence interval (CI): 1.9 to 2.4 g/meal) and estimated energy density 599 kJ/100 g (95% CI 550 to 653 kJ/100 g). Energy density of the male participants’ meals were significantly higher compared with the female participants’ meals (+55 kJ/100 g, 95% CI: +12 to +98 kJ/100 g, p = 0.012), whereas no gender differences were found in macronutrient distribution or fruit and vegetable intake. Compared to the study conducted 10 years before several significant changes were observed, including an increase in mean estimated intake of fruit and vegetables (+38 g/meal, 95% CI: 19 to 57 g/meal, p < 0.001) and a decrease in energy density (−76 kJ/100 g, 95% CI: −115, −37 kJ/100 g, p < 0.001). In conclusion, this study suggests an equalization of gender differences in fruit and vegetable intake and a possible improvement in the nutritional quality of canteen lunch meals over a 10-year period.
Mechanisms of the Complex Thermo-Mechanical Behavior of Polymer Glass Across a Wide Range of Temperature Variations
Authors: Liu Weidong , Zhang Liangchi
Published: October 2018

This paper aims to explore the mechanisms of the complex thermo-mechanical behavior of polymer glass across a wide range of temperature variations. To this end, the free vibration frequency spectrum of simply supported poly(methyl methacrylate) (PMMA) beams was thoroughly investigated with the aid of the impulse excitation technique. It was found that the amplitude ratio of the multiple peaks in the frequency spectrum is a strongly dependent on temperature, and that the peaks correspond to the multiple vibrational modes of the molecular network of PMMA. At a low temperature, the vibration is dominated by the overall microstructure of PMMA. With increasing the temperature, however, the contribution of the sub-microstructures is retarded by β relaxation. Above 80 °C, the vibration is fully dominated by the microstructure after relaxation. The relaxation time at the transition temperature is of the same order of the vibration period, confirming the contribution of β relaxation. These findings provide a precise method for establishing reliable physical-based constitutive models of polymer glass.
The Continuum Approach to the Description of Semi-Crystalline Polymers Deformation Regimes: The Role of Dynamic and Translational Defects
Authors: Grinyaev Yurii , Chertova Nadezhda , Shilko Evgeny , Psakhie Sergey
Published: October 2018

This paper presents a new approach to describe the mechanical behavior of semi-crystalline polymers, the plastic deformation of which is determined by their two-phase structure. To describe the plastic behavior of semi-crystalline polymers, a two-phase model is used. In the framework of this model, one phase is in a hard (crystalline) state, and the other in a soft (amorphous) state. The two-phase material is modeled by a single-phase homogeneous continuum based on the approximation of the effective medium. It is assumed that two infinitely close material points of the continuum are connected in series by elastic and viscous bonds, which corresponds to the Maxwell model. It is shown that, in this case, the Maxwell continuum is a pseudo-Euclidean space. Generalizing the definition of defects from a three-dimensional space to a four-dimensional pseudo-Euclidean space, we obtained a dynamic system of nonlinear, interrelated equations to describe the behavior of translational-type defects in the solid phase and dynamic defects in the amorphous phase. As an example of an application for these equations, the phenomenon of creep under uniaxial loading is considered. It is shown that the formalism of the proposed two-phase model makes it possible to describe creep phenomenon regularities, which correspond to both the aging theory and the flow theory.
A Quiet Faith: Quakers in Post-Christian Britain
Authors: Montemaggi Francesca Eva Sara
Published: October 2018

Post-Christian Britain is characterised by a rejection of doctrinal and morally conservative religion. This does not reflect solely the experience of those with ‘no religion’ but can be found in the narratives of ‘new Quakers,’ those who have become members or attenders in the past three years. New Quakers contrast Quaker sense of acceptance, freedom from theological ideas and freedom to be a spiritual seeker with conservative Christian churches, which have often been experienced as judgmental and doctrinal. Quaker liberal morality also affords inclusivity to those who have felt marginalised, such as disabled and LGBT people. The way new Quakers articulate their identity shines a light on the contemporary transformation of religious forms and society. Their emphasis on individual spirituality and rejection of theological doctrine reflect the profound cultural shift towards a post-Christian Britain, which is religiously diverse, more open to individual spiritual seeking and more liberal morally and socially.
Between Tradition and Transition: An Islamic Seminary, or Dar al-Uloom in Modern Britain
Authors: Sidat Haroon
Published: October 2018

Based on detailed ethnographic fieldwork, this article provides an insider account of life inside a British Dar al-Uloom, or a traditional Islamic religious seminary, for the first time. Given that Dar al-Ulooms play an important role in the British Muslim landscape in providing training for religious leadership, the article argues that, far from the Dar al-Uloom tradition being static, it is undergoing continuous adaptation and change. After mapping the historical and geographical lineage of the modern Dar al-Uloom, the article explores its pedagogy. The postural tradition and adab (broadly translated as comportment or code of behavior) embody the notion of humility, as the classroom has become the locale for balancing a curriculum with depth and coverage, especially given the challenges young Muslims in Britain are facing. The current students of the Dar al-Uloom will become imams and faith leaders primarily responsible for addressing the changing needs of young Muslims. What has emerged is a traditional Dar al-Uloom that is in a dialogical relationship both with the modern world outside of it and within it. There is the need to embody a ‘tarbiyyatic pedagogy’ that is one that emphasises the student-teacher relationship where the student is transformed in the process of learning while interpreting Islam through the lens of the Deobandi universe. Ultimately, it will be the younger generation of teachers who determine the particular trajectory of the Dar al-Uloom.
Vegetation Characterization through the Use of Precipitation-Affected SAR Signals
Authors: Molijn Ramses , Iannini Lorenzo , López Dekker Paco , Magalhães Paulo , Hanssen Ramon
Published: October 2018

Current space-based SAR offers unique opportunities to classify vegetation types and to monitor vegetation growth due to its frequent acquisitions and its sensitivity to vegetation geometry. However, SAR signals also experience frequent temporal fluctuations caused by precipitation events, complicating the mapping and monitoring of vegetation. In this paper, we show that the influence of a priori known precipitation events on the signals can be used advantageously for the classification of vegetation conditions. For this, we exploit the change in Sentinel-1 backscatter response between consecutive acquisitions under varying wetness conditions, which we show is dependent on the state of vegetation. The performance further improves when a priori information on the soil type is taken into account.
An Optical Crack Growth Sensor Using the Digital Sampling Moiré Method
Authors: Chen Xinxing , Chang Chih-chen , Xiang Jiannan , Zhang Chaobo , Liu Ming
Published: October 2018

High-accuracy crack growth measurement is crucial for the health assessment of concrete structures. In this work, an optical crack growth sensor using the digital sampling moiré (DSM) method is developed for two-dimensional (2D) crack growth monitoring. The DSM method generates moiré fringes from a single image through digital image processing, and it measures 2D displacements using the phase difference of moiré fringes between motion. Compared with the previous sensors using traditional photogrammetric algorithms such as the normalized cross-correlation (NCC) method, this new DSM-based sensor has several advantages: First, it is of a higher sensitivity and lower computational cost; second, it requires no prior calibration to get accurate 2D displacements which can greatly simplify the practical application for multiple crack monitoring. In addition, it is more robust to the change of imaging distance, which is determined by the height difference between two sides of a concrete crack. These advantages break the limitation of the NCC method and broaden the applicability of the crack growth sensor. These advantages have been verified with one numerical simulation and two laboratory tests.
Roll Angle Measurement for a Spinning Vehicle Based on GPS Signals Received by a Single-Patch Antenna
Authors: Deng Zilong , Shen Qiang , Deng Zhaowei
Published: October 2018

Roll angle measurement is an essential technology in the trajectory correction projectiles. In this paper, an algorithm to detect the roll angle and rotational speed of a spinning vehicle is studied by using a GPS (Global Positioning System) receiver with a single side-mounted antenna. A Frequency-Locked Loop (FLL) assisted Phase-Locked Loop (PLL) is designed to obtain the attitude information from GPS signals, and the optimal parameters of this system are discussed when different rotational speeds are considered. The error estimation of this method and signal-to-noise ratio analysis of GPS signals are also studied. Finally, experiments on the rotary table were carried out to verify the proposed method. The experimental results showed that the proposed algorithm can detect the roll angle in a precision of within 5 degrees.
Inequality Perceptions, Preferences Conducive to Redistribution, and the Conditioning Role of Social Position
Authors: Fatke Matthias
Published: October 2018

Inequality poses one of the biggest challenges of our time. It is not self-correcting in the sense that citizens demand more redistributive measures in light of rising inequality, which recent studies suggest may be due to the fact that citizens’ perceptions of inequality diverge from objective levels. Moreover, it is not the latter, but the former, which are related to preferences conducive to redistribution. However, the nascent literature on inequality perceptions has, so far, not accounted for the role of subjective position in society. The paper advances the argument that the relationship between inequality perceptions and preferences towards redistribution is conditional on the subjective position of respondents. To that end, I analyze comprehensive survey data on inequality perceptions from the social inequality module of the International Social Survey Programme (1992, 1999, and 2009). Results show that inequality perceptions are associated with preferences conducive to redistribution particularly among those perceived to be at the top of the social ladder. Gaining a better understanding of inequality perceptions contributes to comprehending the absence self-correcting inequality.
The Regional Governance of Energy-Neutral Housing: Toward a Framework for Analysis
Authors: De Leeuw Laura , Groenleer Martijn
Published: October 2018

Regions are expected to play a key role in realizing international, European, and national climate and energy goals. Also regions in the Netherlands are working toward these goals, taking initiatives toward an energy-neutral built environment by 2050. However, it remains unclear how such efforts and other socially innovative activities can best be described and how variation between them in terms of governance can be explained. In this article, we develop a framework for analyzing the governance of regional energy-neutral housing initiatives. We ask what factors shape regional climate and energy governance, particularly regional efforts to increase the efficiency of urban dwellings. We answer this question using a subnational comparative method and a most similar case design, focusing on three Dutch regions: Utrecht, Noord-Brabant and Drenthe. Based on document analysis and 24 semi-structured interviews, we find that the regional governance of energy-neutral housing initiatives is primarily driven by existing social networks in the regions, and less determined by local characteristics of the built environment. Thus, regional governance seems to have generated solutions that are supported by regional actors. Nonetheless, as these solutions are not entirely tailored to the regional situation, functionally speaking, a key question for future research is how effective these solutions will be.
The Cosmological Perturbed Lightcone Gauge
Authors: Elmardi Maye
Published: October 2018

The lightcone gauge is a set of what are called the observational coordinates adapted to our past lightcone. We develop this gauge by producing a perturbed spacetime metric that describes the geometry of our past lightcone where observations are usually obtained. We connect the produced observational metric to the perturbed Friedmann-Lemaître-Robertson-Walker (FLRW) metric in the standard general gauge or what is the so-called 1+3 gauge. We derive the relations between these perturbations of spacetime in the observational coordinates and those perturbations in the standard metric approach, as well as the dynamical equations for the perturbations in observational coordinates. We also calculate the observables in the lightcone gauge and re-derive them in terms of Bardeen potentials to first order. A verification is made of the observables in the perturbed lightcone gauge with those in the standard gauge. The advantage of the method developed is that the observable relations are simpler than in the standard formalism, and they are expressed in terms of the metric components which in principle are measurable. We use the perturbed lightcone gauge in galaxy surveys and the calculations of galaxy number density contrast. The significance of the new gauge is that by considering the null-like light propagations the calculations are much simpler due to the non-consideration of the angular deviations.
Locational Attractiveness Modelling of Retail in Santa Maria, Brazil
Authors: Paroli Eliziéle , Maraschin Clarice
Published: October 2018

A central topic in the retail analysis is store location, which is related to its attractiveness and even with its profitability. In order to determine the force of attraction of a given point of sale, methodologies based on gravitational models have been developed. More recently, classic models have been integrated with Geographic Information Systems (GIS). This paper explores a methodology for retail spatial analysis in a GIS environment, and it aims to: (a) model the degree of influence of different store location attributes on the consumer choice among a collection of retail options, and (b) develop an empirical application for the clothing retail business sector in the city of Santa Maria, RS, Brazil. The study selects three relevant location attributes of store choice: retail market clustering, local accessibility of the street network, and topographic slope of the terrain. These three location features were taken as inputs for the attractiveness evaluation of each store, using the Huff model. As a result, we were able to model the trading areas of each shop related to the selected attributes. The paper provides a methodology for modelling the performance of retail location attributes and building different scenarios of probabilities for consumer patronage, allowing a first measure of the influence of each selected store location attribute.
The Construction and Comparison of Regional Drought Severity-Duration-Frequency Curves in Two Colombian River Basins—Study of the Sumapaz and Lebrija Basins
Authors: Torres Rojas Laura Patricia , Díaz-Granados Mario
Published: October 2018

Accurate classification of drought-severity is one of the most challenging issues in designing regional monitoring and control plans, especially in developing countries, where resources are scarce and must be carefully optimized to maximize social benefit. Typically, drought assessment is performed using drought indices which enable the interpretation of complex climatic information series for operational purposes. Frequency analyses are also useful for estimating future occurrence probabilities, even on regional scales. This study generated regional Severity-Duration-Frequency (SDF) curves for two Colombian catchments (Sumapaz and Lebrija River Basins), and 7 index-calculation procedures. First, the relationships between the two catchments were analyzed to obtain differences between drought indices. Second, the consistency among the indices that identified the same drought types for each region was evaluated. Finally, historical regional drought occurrences were selected, characterized, and located in local SDF curves to determine their gravity. It was concluded that (i) curves for the same indices displayed similar behavior, when comparing the two case studies; (ii) a certain degree of consistency existed in regional curves, which identify the same drought types (meteorological and agricultural droughts being the most coherent); (iii) meteorological drought regional events, identified through different drought-indices methodologies, were the most common for both case studies, followed by agricultural droughts and hydrological droughts; (iv) when analyzing occurrences with higher return periods, there is coherence when using different methodologies; and (v) identified historical events, which are located on larger return period zones of SDF curves (around 10, 25, and 50 years), had large impacts on regional socio-economic issues. Hence, it was possible to confirm that regional SDF curves could become potentially useful tools for the prioritization of drought-vulnerable zones.
A Multi-GCM Assessment of the Climate Change Impact on the Hydrology and Hydropower Potential of a Semi-Arid Basin (A Case Study of the Dez Dam Basin, Iran)
Authors: Mousavi Roya Sadat , Ahmadizadeh Mojtaba , Marofi Safar
Published: October 2018

In this paper, the impact of climate change on the climate and discharge of the Dez Dam Basin and the hydropower potential of two hydropower plants (Bakhtiari and Dez) is investigated based on the downscaled outputs of six GCMs (General Circulation Models) and three SRES (Special Report on Emission Scenarios) scenarios for the early, mid and late 21st century. Projections of all the scenarios and GCMs revealed a significant rise in temperature (up to 4.9 °C) and slight to moderate variation in precipitation (up to 18%). Outputs of the HBV hydrologic model, enforced by projected datasets, show a reduction of the annual flow by 33% under the climate change condition. Further, analyzing the induced changes in the inflow and hydropower generation potential of the Bakhtiari and Dez dams showed that both inflow and hydropower generation is significantly affected by climate change. For the Bakhtiari dam, this indicates a consistent reduction of inflow (up to 27%) and electricity generation (up to 32%). While, in the Dez dam case, the inflow is projected to decrease (up to 22%) and the corresponding hydropower is expected to slightly increase (up to 3%). This contrasting result for the Dez dam is assessed based on its reservoir and hydropower plant capacity, as well as other factors such as the timely releases to meet different demands and flow regime changes under climate change. The results show that the Bakhtiari reservoir and power plant will not meet the design-capacity outputs under the climate change condition as its large capacity cannot be fully utilized; while there is room for the further development of the Dez power plant. Comparing the results of the applied GCMs showed high discrepancies among the outputs of different models.

DEVELOPMENT OF A THEORETICAL APPROACH TO THE CONDITIONAL OPTIMIZATION OF AIRCRAFT MAINTENANCE PREFERENCE UNCERTAINTY
Authors: Goncharenko Andriy
Published: October 2018

The paper builds on the ideas of previous research concerning the theoretical explanation of the aircraft operational process with regard to the preferences for maintenance organization by experts and aircraft operators, and describes the designed mathematical models. The problem of conditional extremization is considered. The uncertainty of aircraft technical operation multi-alternativeness is evaluated using the subjective entropy of the aircraft operators’ and experts’ preferences. By applying the subjective entropy extremization principle in view of its maximum, we obtain the conditional optimal distributions of the preferences. The proposed approach allows finding the optimal distribution of the aircraft fleet for the available maintenance alternatives, taking into consideration the restricted possible influences or shadow components of maintenance organizations. The concepts discussed here are important for evaluating the effectiveness of the aviation industry by making allowance for shadow parameters, if needed. The designed model is illustrated with diagrams.
The Enigmatic Compact Radio Source Coincident with the Energetic X-Ray Pulsar PSR J1813–1749 and HESS J1813–178

Published: October 2018

New Very Large Array (VLA) detections of the variable radio continuum source VLA J181335.1−174957, associated with the energetic X-ray pulsar PSR J1813−1749 and the TeV source HESS J1813–178, are presented. The radio source has a right circular polarization of ∼50% and a negative spectral index of −1.3 ± 0.1, which show that it is nonthermal. The radio pulses of the pulsar are not detected from additional Effelsberg observations at 1.4 GHz made within one week of a VLA detection. This result would appear to support the idea that the continuum radio emission detected with the VLA does not trace the time-averaged emission pulses, as had previously been suggested. We discuss other possible origins for the radio source, such as a pulsar wind, magnetospheric emission, and a low-mass star companion. However, observations made at higher frequencies by Camilo et al. show that the VLA source is in fact the time-averaged pulsed emission and that the detection of the pulses had not been achieved because this is the most scattered pulsar known.
Glitch Behavior of Pulsars and Contribution from Neutron Star Crust
Authors: Basu Avishek , Char Prasanta , Nandi Rana , Chandra Joshi Bhal , Bandyopadhyay Debades
Published: October 2018

Pulsars are highly magnetized rotating neutron stars (NSs) with a very stable rotation speed. Irrespective of their stable rotation rate, many pulsars have been observed to feature a sudden jump in the spin frequency, known as a pulsar glitch. The glitch phenomena are considered to be an exhibit of superfluidity of neutron matter inside the NS’s crustal region. The magnitude of such a rapid change in rotation rate relative to the stable rotation frequency can quantify the ratio of the moment of inertia (MoI) of the crustal region to the total MoI of the star, also called the fractional moment of inertia (FMI). In this paper, we have calculated the FMI for different masses of a star using six different representative unified equations of state constructed under a relativistic mean field framework. We have performed an event-wise comparison of the FMI obtained from data with that from theoretically calculated values with and without considering the entrainment effect. It is found that larger glitches cannot be explained by the crustal FMI alone, even without entrainment.
The Role of Black Hole Feedback on Size and Structural Evolution in Massive Galaxies
Authors: Choi Ena , Somerville Rachel S. , Ostriker Jeremiah P. , Naab Thorsten , Hirschmann Michaela
Published: October 2018

We use cosmological hydrodynamical simulations to investigate the role of feedback from accreting black holes in the evolution of the size, compactness, stellar core density, and specific star formation of massive galaxies with stellar masses of

. We perform two sets of cosmological zoom-in simulations of 30 halos to z = 0: (1) without black holes and active galactic nucleus (AGN) feedback and (2) with AGN feedback arising from winds and X-ray radiation. We find that AGN feedback can alter the stellar density distribution, reduce the core density within the central 1 kpc by 0.3 dex from z = 1, and enhance the size growth of massive galaxies. We also find that galaxies simulated with AGN feedback evolve along tracks similar to those characterized by observations of specific star formation rate versus compactness. We confirm that AGN feedback plays an important role in transforming galaxies from blue compact galaxies into red extended galaxies in two ways: (1) it effectively quenches the star formation, transforming blue compact galaxies into compact quiescent galaxies, and (2) it also removes and prevents new accretion of cold gas, shutting down in situ star formation and causing subsequent mergers to be gas-poor or mixed. Gas-poor minor mergers then build up an extended stellar envelope. AGN feedback also puffs up the central region through fast AGN-driven winds as well as the slow expulsion of gas while the black hole is quiescent. Without AGN feedback, large amounts of gas accumulate in the central region, triggering star formation and leading to overly massive blue galaxies with dense stellar cores.
Synthetic cartography for mapping biodiversity in the Mediterranean region: Sicily as a case study
Authors: Domina Gianniantonio , Venturella Giuseppe , Gargano Maria Letizia
Published: October 2018

This paper proposes a new hierarchical land classification system for the mapping of species distribution at national or regional scales. Our integrative framework incorporates two hierarchical levels inferred from historical, climatic, geomorphological and geological attributes. The feasibility of this proposal is based on the use of historical collections and literature data, as well as on its ability to combine old low-precision data with more recent records of higher resolution. The system is set up for vascular plants, but it can also be used for other taxonomic groups. Furthermore, it has the potential for application to the whole Mediterranean region because it is based on information that is generally available in all Mediterranean countries. This model is tested with the distribution ofloci classiciof the Italian endemic plants occurring in Sicily.

Published: October 2018

Même si le nombre de séparations et de divorces est plutôt stable depuis quelques années, la structure des familles post-séparation continue à se diversifier. La séparation est une période critique pour les membres de la famille qui peut comporter des défis, notamment sur le plan de la résolution des conflits et du maintien des relations. À cet effet, il existe plusieurs services destinés aux parents qui se séparent, dont la médiation familiale. Parce que les besoins de l’enfant sont au cœur du processus de médiation familiale, des acteurs s’interrogent sur la place réelle qu’on doit lui accorder dans ce processus. L’inclusion de l’enfant dans la médiation familiale est appelée à se développer dans les prochaines années si l’on conjugue évolution du statut de l’enfant dans la société et dans les législations et réalité du vécu des parents séparés en conflits. Mais les médiateurs familiaux sont-ils prêts à investir cette nouvelle forme de pratique ? Quels sont les avantages et enjeux de cette pratique ?
L’exposition des enfants au conflit sévère de séparation. Les défis particuliers pour la pratique en protection au Québec

Published: October 2018

Au Québec, c’est depuis 2007 que la loi québécoise sur la protection de la jeunesse inclut les mauvais traitements psychologiques (MTP) comme motif recevable de signalement. Dans les trois ans ayant suivi cette inclusion, un premier portrait québécois montre que la vaste majorité des situations de MTP retenue pour évaluation implique une exposition de l’enfant à la violence conjugale ou à un conflit sévère entre ses parents séparés. Ce dernier type de situation pose des défis particuliers pour les intervenants en protection. Le présent article présente brièvement le système de protection québécois et la littérature recensée sur l’exposition des enfants au conflit sévère de séparation, avant d’illustrer à l’aide d’histoires de cas les principaux défis posés par cette problématique pour la pratique en protection.

L’objectif du projet est de venir en aide aux familles qui présentent une dynamique hautement conflictuelle en sensibilisant les parents aux effets indésirables du conflit sur leurs enfants et en favorisant une coordination parentale pour mettre les enfants à l’abri.
Le temps suspendu du divorce : travail psychique de gestion des pertes ambiguës et construction des nouvelles appartenances
Authors: D’Amore Salvatore
Published: October 2018

La séparation, bien que de plus en plus fréquente, reste une transition critique. Un cortège de pertes relationnelles suit cet évènement et dans certaines situations, le temps familial peut se cristalliser autour de l’impossibilité de reproduire une identité perdue et de recréer des nouvelles appartenances. À l’aide de la méthode des sculptures du temps employée dans la prise en charge thérapeutique d’une famille divorçante, nous explorerons la pertinence du lien entre pertes relationnelles et temps suspendu. L’analyse de cas fait émerger l’importance d’un travail analogique et narratif avec les patients et leurs familles afin de pouvoir gérer l’ambiguïté des pertes et de redynamiser temps subjectif et familial. Cette perspective semble être porteuse pour le travail avec toute famille et en particulier avec certaines nouvelles familles qui ont connu beaucoup de ruptures et qui n’arrivent pas à établir des projets pour leur futur.

L’article décrit différents types de situations rencontrées dans ce contexte et propose une série d’attitudes qui permettraient aux parents d’offrir les meilleures conditions de développement émotionnel et psychique à leurs enfants.
Construire la cohésion familiale : les relations coparentales dans les familles recomposées
Authors: Favez Nicolas , Widmer Éric D. , Doan Minh-Thuy , Tissot Hervé
Published: October 2018

Une relation coparentale soutenante est au cœur de la cohésion familiale, celle-ci constituant un contexte de développement favorable pour l’enfant. Nous connaissons encore peu la relation coparentale entre parent gardien, souvent la mère, et son nouveau partenaire dans les familles recomposées, et en quoi cette relation ressemble (ou non) à la relation coparentale entre mère et père. L’étude présentée dans cet article s’est intéressée aux comportements coparentaux rapportés par les mères dans des familles recomposées et dans des familles de première union. Trois dimensions coparentales ont été prises en compte : la promotion de l’unité familiale, le dénigrement et les conflits. Les mères (N = 300) ont évalué par questionnaire leur relation coparentale, ainsi que leur modèle d’attachement et leur satisfaction conjugale. La moitié de ces mères vivaient en famille recomposée avec au moins un enfant entre 5 et 13 ans issu d’une union précédente ; l’autre moitié vivait dans une famille de première union avec un enfant de la même tranche d’âge. Les résultats montrent que les relations coparentales ont des caractéristiques similaires dans les deux types de familles, mais qu’il y a également des différences qui sont importantes à prendre en compte, notamment dans le travail clinique avec des parents qui ont reconstitué une nouvelle famille.
Après la séparation… Comment aider les enfants placés en institution à garder un sentiment de continuité ?
Authors: Catry Carole , Dubus Constance
Published: October 2018

Nous témoignons dans cet article de notre travail clinique en consultation avec des enfants et des adolescents placés, ainsi que de notre approche avec leurs parents et les institutions. Ces suivis sont à géométrie variable, en termes de fréquence, de participants et d’outils utilisés. Nous adaptons notre dispositif en fonction des particularités de chacune des situations. Nos interventions visent à aider l’enfant à se bâtir une sécurité interne afin de bien grandir. Nous travaillons à instaurer une continuité au travers des discontinuités et avons pour but d’aider l’enfant à se construire une représentation de son histoire qui fasse sens pour lui. Ce type d’accompagnement doit être pensé sur le long terme. Quand un réel partenariat se met en place avec les parents et les institutions, le travail est alors plus efficient. Il nécessite donc de la patience et du tissage pour obtenir une bonne alliance de soins.
Le rôle du formateur dans l’articulation des compétences acquises sur simulateur et des compétences cibles (« terrain »)
Authors: Rogalski Janine , Colin Boris
Published: October 2018

L’étude interroge l’activité de formation sur simulateur pour l’acquisition des compétences cibles en situation réelle. Elle s’appuie sur le cas de la formation initiale au pilotage d’hélicoptères militaires. Cette formation très encadrée articule séances sur simulateur et vols réels, visant à la maîtrise des manœuvres au cœur du pilotage. L’activité du formateur est également très encadrée avec une organisation préalable des tâches, un guidage pour le déroulement des séances, évaluation comprise. La référence théorique retenue est celle de la didactique professionnelle (Pastré, Mayen, & Vergnaud, 2006). La médiation didactique exercée par le formateur est analysée en transposant la notion d’étayage théorisée par Bruner (2002). Les données de la littérature sur la conduite de mobiles sont convoquées pour situer les questions ouvertes sur la place de la simulation dans la formation. Le rôle des moniteurs dans l’articulation des compétences des élèves sur simulateur et sur le terrain est traité dans une étude de cas qui s’appuie sur l’expertise du second auteur (pilote, formateur et concepteur d’outils pour les moniteurs). On vise en particulier à préciser l’activité d’étayage selon les situations. La discussion porte sur le domaine de pertinence des analyses proposées pour les apprentissages dans des types de situations professionnelles marquées par la place des activités sensori-motrices, par la complexité des interactions entre commandes d’action, et par les relations entre procéduralisation des tâches et ouverture de l’environnement dynamique.
Intervention, conception et transformations : Comment construire une prévention durable des TMS ?
Authors: Ciccone Elodie , Cuvelier Lucie , Decortis Françoise , Bationo-Tillon Anne
Published: October 2018

Cet article a pour but de participer aux réflexions sur le rôle de l’ergonome dans l’intervention en entreprise. Il présente une intervention-formation relative à la prévention de la pénibilité et des TMS au travail. Cette intervention, menée comme une conduite de projet, s’est basée sur l’adoption de principes fondamentaux pour l’ergonomie dite centrée sur l’activité (Daniellou & Rabardel, 2005). Ces principes portent sur (1) la conception et la pérennisation des démarches de prévention durable, (2) la conduite et l’efficacité des interventions en ergonomie. Sur la base de ce corps de connaissances et de nos pratiques d’intervention antérieures, nous postulons que la mobilisation des acteurs et la transformation des représentations/perceptions sur le travail et la santé participent à l’augmentation du pouvoir d’agir des acteurs en matière de prévention. Ces principes sont illustrés et discutés à partir des résultats d’une intervention menée dans un abattoir de canards.
Fatores determinantes dos acidentes do trabalho: um estudo exploratório para o mercado formal de trabalho do estado de São Paulo utilizando Regressão Logística.
Authors: Galete Rinaldo
Published: October 2018

Os acidentes de trabalho são fenômenos complexos e socialmente determinados. Acidentes de trabalho constituem um importante problema de saúde pública no Brasil. Apesar da gravidade dos seus custos econômicos e sociais decorrentes dos acidentes de trabalho e o Ministério da Saúde apoiar pesquisas em todo o Brasil para aprofundar os conhecimentos e discussões a respeito do tema, não existem muitos estudos sobre o presente tema. Este importante problema de saúde pública deve ser objeto de estudo de todos os profissionais envolvidos na área atinente a esse tema. O objetivo geral do presente estudo é verificar os principais fatores determinantes dos acidentes do trabalho no mercado de trabalho formal do estado de São Paulo, a partir dos micro dados da Relação Anual de Informações Sociais - RAIS, para o ano de 2015, através de um modelo de Regressão Logística.

Published: October 2018

Microporous aluminum fumarate (A520) is one of the very few metal-organic frameworks (MOFs) that have been promoted to the level of commercial applications and has recently been proven to exhibit a rigid character with an accessible permanent porosity. This study explored the maximum loading amount of A520 for mixed matrix membrane (MMM) preparation by blending it with polyimide (PI) using N-methylpyrrolidone (NMP) as solvent, without compromising the membrane integrity. Scanning electron microscope (SEM) images revealed that MOFs were able to infiltrate the pores and structures of the polymer, improving the interface and mechanical properties of the polymer, as supported by different characterizations like dynamic mechanical analysis (DMA), x-ray diffraction (XRD), and positron annihilation lifetime spectroscopy (PALS). Results showed that MOF loading beyond 10wt% revealed aggregations that compromised the integrity of the membrane.
