Scaffolding for motivation by parents, and child homework motivations and emotions: Effects of a training programme
Authors: Moè Angelica , Katz Idit , Alesi Marianna 
Published: March 2018

Background and aimsBased on the principles of scaffolding for motivation and on the assumptions of self‐determination theory, two studies aimed to assess the role played by perceived parental autonomy‐supportive scaffolding on child homework autonomous motivation, self‐efficacy, affect, and engagement.Samples and resultsThe results of Study 1, which involved 122 parents and their children, showed that the higher the parental autonomous motivation, the more their children perceived them as autonomy‐supportive while scaffolding for motivation, and hence developed autonomous motivation, self‐efficacy, and engagement in homework. In Study 2, 37 parents were involved in a four‐session training programme that focused on sustaining autonomy‐supportive scaffolding modalities. The training decreased parental negative affect, prevented child negative affect increase, and maintained child homework motivation.ConclusionsThe discussion focuses on the strength that parents have with regard to helping their children develop less negative, and potentially also more positive attitude towards homework, through autonomy support as a scaffold for motivation.

AbstractAstrocytes with multiple micronuclei (“Creutzfeldt cells”) in a brain biopsy are classically associated with demyelinating disease. However, glioblastoma may also have prominent Creutzfeldt astrocytes, along with granular mitoses. Therefore, Creutzfeldt cells may raise the diagnostic dilemma of high‐grade glioma vs tumefactive demyelination. While cases of glioblastoma (GBM) with Creutzfeldt astrocytes have been reported, their clinicopathologic spectrum and genetic features are not understood. Studies have proposed that micronuclei in Creutzfeldt cells are a consequence of DNA damage, or may be susceptible to DNA damage and chromothripsis, but their biology in the context of glioblastoma remains unclear. Based on a challenging index case of GBM with mild hypercellularity, Creutzfeldt astrocytes, and granular mitoses on biopsy, we searched our archives for additional cases with similar histopathologic features. We identified 13 cases, reviewed their clinico‐radiologic and pathologic features, and examined them for recurrent genetic alterations via NGS (9 cases) and for evidence of DNA damage by immunohistochemistry for DNA repair and chromatin remodeling proteins. We found that Creutzfeldt cell‐rich GBMs were IDH‐wildtype with no recurring genetic alterations. To test our hypothesis that micronuclei demonstrate loss of DNA repair or chromatin remodeling proteins, we examined the expression of various proteins (MDM2, p53, MLH1, MSH2, PMS2, MSH6, ATRX, INI1, SATB2, Ki67, pHH3) in Creutzfeldt cell rich‐GBM. There was intact expression of DNA repair and chromatin remodeling proteins, with accumulation of p53 and reduced MDM2 expression within micronuclei. In contrast, granular mitoses showed pHH3 expression, confirming these cells are undergoing mitotic division, with no accumulation of p53 and reduced expression of DNA repair proteins. Our results emphasize that Creutzfeldt cells are part of the morphologic spectrum of IDH‐wildtype glioblastoma. We did not find a role for DNA damage in the generation of Creutzfeldt cells, as both DNA repair and chromatin remodeling protein expression was retained in these cells.
Measuring and modelling the land‐use intensity and land requirements of utility‐scale photovoltaic systems in the Canadian province of Ontario
Authors: Calvert Kirby E. 
Published: March 2018

AbstractThis paper summarizes the land‐use impacts and land requirements of utility‐scale photovoltaic (U‐PV) systems in the Canadian province of Ontario. The empirical research is based on an analysis of approximately 95 projects representing over 1000 MW of U‐PV systems province‐wide. Findings from this empirical assessment are combined with information about future technological advances in order to develop a modelling framework that can forecast land requirements of U‐PV systems within evolving market and technology contexts. Specifically, the model is used to estimate the land requirements of U‐PV systems in a hypothetical future in which U‐PV systems supply all mid‐day electricity needs in Ontario, including added demands from a completely electrified light‐duty vehicle fleet. Under this scenario, on an installed capacity basis and assuming that 20% of mid‐day electricity demand is met with rooftop PV, an area equivalent to 0.5% to 8.5% of Ontario's agricultural land would be required, depending on panel efficiencies and system packing factors. These land requirements are manageable, particularly as more land‐efficient technologies are deployed and as regulations are designed to mitigate the land‐use impacts of U‐PV systems.

AbstractBackgroundSingle piece implant in fixed prosthesis is widely been evaluated, however, long term evaluation of crestal bone loss and the wear of O‐ring in single piece ball attachment implant supported overdenture is yet to be evaluatedPurposeThe present article evaluates the crestal bone loss around single piece ball attachment implants placed bilaterally in the canine region and the wear of O‐ring in implant supported overdenture over a period of three years.Materials and MethodsTwelve completely edentulous patients between the age group of 55‐65 years were selected. Two 3.3 mm × 13 mm myriad snap fit implants were placed in the mandibular interforaminal region. All the implants were conventionally loaded at three months after surgical placement. Intra‐oral periapical radiographs were made and crestal bone loss was measured at the end of one year and three years. The elasticity and wear of O‐Ring was assessed after three years of usage.ResultsThe crestal bone loss showed no significant difference between the first and third year after implant placement. The mean bone loss at the end of third year was 1.5 mm. Analysis of O‐ring for change in the elasticity showed reduction in displacement and a significant increase in maximum displacement and elongation. The area of O‐ring and yield stress did not show any changes from the standard value. Compression set damage was observed in the O‐ring at the end of three years.ConclusionsThe present study shows that the bilateral single piece implant supported overdenture has a success rate equivalent to the two piece implant supported overdenture and is a viable treatment option.

AbstractStatement of ProblemEvaluate the effect of orbital prosthesis retained by implants through a specific quality of life (QOL) questionnaire provides important information on patients QOL, great incentive for the multidisciplinary team and public health support to continue work in this area.PurposeThe objective of the study was to evaluate patient satisfaction with orbital implant‐supported prostheses using an adapted quality of life questionnaire.Materials and MethodsForty five patients using orbital implant‐supported prostheses for a period ranging from six to 120 months. The subjects answered a questionnaire that consisted of 10 questions covering appearance, retention, conspicuousness, self‐confidence, difficulty of placement, difficulty of removal, cleaning, limitation of activities, discomfort of tissues, and recommendation of the method to other patients. Answers were expressed using a visual 100‐mm scale. The arithmetic mean of the responses was converted into a percentage to represent the satisfaction index.ResultsPatients demonstrated a high level of satisfaction on all items, with the lowest rate being for aesthetics and the highest being for recommending the method to other patients. High satisfaction rates regarding the placement and removal of the prosthesis, discomfort to the tissues, and cleaning suggest the ease of handling of the prosthesis. High satisfaction with retention, self‐confidence, conspicuousness of the prosthesis, and limitation of activities indicated an association with a better social life.ConclusionsThe results showed that use of bone anchorage technique of extraoral prostheses provided a high level of satisfaction among patients, confirming that osseointegrated implants are a very important resource for the rehabilitation of orbital deformities.
Forgiveness as singularity: The “Allah” controversy in Malaysia and the church's public discourse of cheek‐turning
Authors: Lau Alwyn 
Published: March 2018

AbstractThis paper adopts a Lacanian motif to present the world as being psycho‐theologically characterized by sacrifice and loss, with its subjects (including, more often than not, Christians) remaining in bondage to a vicious cycle of tit‐for‐tat violence and retribution. The chief solution to this situation is for the church to mimic the mercy, forgiveness, and cheek‐turning displayed by Jesus. Through via unconditional forgiveness in the face of injustice and oppression, the community defined by the enemy‐loving work of Christ can exemplify an unravelling of the present diabolical world system. In Lacanian terms, the church is responsible to initiate an ongoing assault of the Real (of peace‐making and forgiveness) upon the Symbolic Order (of rights‐seeking and oppression). This article argues that turning the cheek is no mere political tactic, but is indeed the church's singularity, that is, that aspect of a subject whose jouissance (or enjoyment) refuses the validation of the Other. It concludes by highlighting two episodes from the “Allah” controversy in Malaysia where Christian leaders prioritized forgiveness and reconciliation over legal reprisal.
Diversity and diversification in ECEC practices: Considerations from Serbia
Authors: Miškeljin Lidija , Sharmahd Nima 
Published: March 2018

AbstractFocusing on diversity represents a step forward towards a complex concept of quality in the early childhood education and care (ECEC) system. The diversification of programmes and services takes shape within this framework, bringing a shift from purely technical issues towards a joint construction of the community's culture. Its complexity is visible in its conceptualisation, which combines theoretical and ideological key points concerning childhood, learning, development, well‐being and the role of adults and of public policy. This article presents the process and results of a project that included a study to better understand the perspective of professionals, parents and representatives of local policymakers on the meanings given to the diversification of programmes in the ECEC system in Serbia. The method was participatory, with focus groups supporting participants in expressing their opinions and in co‐creating meanings and knowledge, linking research to group reflection. The aim was to identify practices related to these meanings in a coherent way, focusing on the concepts of well‐being and respect for diversity. The main conclusion is a strong need for a multilevel network to: (a) support policymakers and professionals in creating socially‐mixed contexts, (b) support parents by making them feel that they are partners in the educational system, and (c) invest in continuous professional development (CPD) programmes for professionals to train them and encourage them to co‐reflect on practice.
Equine cheek teeth occlusal fissures: Prevalence, association with dental wear abnormalities and occlusal angles

Published: March 2018

SummaryBackgroundFissures of the occlusal surface of equine cheek teeth are commonly encountered during oral examination but their aetiology is unknown.ObjectivesTo examine the prevalence and characteristics of occlusal fissures in cadaver teeth. It is hypothesised that their prevalence is influenced by masticatory forces. Consequently, their possible association with wear disorders and occlusal angles were examined.Study designCross‐sectional survey.MethodsThe dental abnormalities and occlusal fissure findings in the cheek teeth of 143 cadaver heads were recorded. The cheek teeth occlusal angles were measured using the stiff‐hinge technique. Multiple regression analyses were performed to establish possible relationships between age, sex, dental wear, occlusal angle and fissure prevalence.ResultsOcclusal fissures were found in 103/143 (72%) heads. Sex and age were determining factors in the prevalence of fissures. A similar prevalence was found in mandibular (54.1%) and maxillary teeth (45.9%, OR = 1.10; 95% CI = 0.95–1.29, P = 0.2). Mandibular fissures were more commonly located on the buccal aspect (OR = 1.42; 95% CI = 1.16–1.65, P < 0.001), whereas for maxillary fissures there was no difference in prevalence between palatal and buccal aspects (OR = 1.19; 95% CI = 0.97–1.46, P = 0.1). Two main fissure types were identified. Type 1a fissures were the most prevalent type (39.5%). No significant correlation was found between the presence of wear abnormalities or the occlusal angle of cheek teeth, and the prevalence of fissures.Main limitationsNo dental histories were available.ConclusionEquine cheek teeth show a high prevalence of occlusal fissures. Despite some evidence of predilection sites on the tooth surface that might indicate a mechanical aetiology for these lesions, no associations were found with wear abnormalities or occlusal angles of affected cheek teeth. Further histological and ultrastructural studies are warranted to elucidate their aetiology and possible role in other dental diseases.
Evaluating Micrometeorological Estimates of Groundwater Discharge from Great Basin Desert Playas

Published: March 2018

AbstractGroundwater availability studies in the arid southwestern United States traditionally have assumed that groundwater discharge by evapotranspiration (ETg) from desert playas is a significant component of the groundwater budget. However, desert playa ETg rates are poorly constrained by Bowen ratio energy budget (BREB) and eddy‐covariance (EC) micrometeorological measurement approaches. Best attempts by previous studies to constrain ETg from desert playas have resulted in ETg rates that are within the measurement error of micrometeorological approaches. This study uses numerical models to further constrain desert playa ETg rates that are within the measurement error of BREB and EC approaches, and to evaluate the effect of hydraulic properties and salinity‐based groundwater density contrasts on desert playa ETg rates. Numerical models simulated ETg rates from desert playas in Death Valley, California and Dixie Valley, Nevada. Results indicate that actual ETg rates from desert playas are significantly below the uncertainty thresholds of BREB‐ and EC‐based micrometeorological measurements. Discharge from desert playas likely contributes less than 2% of total groundwater discharge from Dixie and Death Valleys, which suggests discharge from desert playas also is negligible in other basins. Simulation results also show that ETg from desert playas primarily is limited by differences in hydraulic properties between alluvial fan and playa sediments and, to a lesser extent, by salinity‐based groundwater density contrasts.

AbstractIntroductionThere are 7 designated conditions under the category of myeloproliferative neoplasms (MPN), including chronic myelogenous leukemia (CML) and classical MPN, that is, polycythemia vera (PV), essential thrombocythaemia (ET), and primary myelofibrosis (PMF). Recently, reports about Philadelphia and JAK2 V617F‐positive MPN cases have been described in literature. The coexistence of different molecular defects may change the clinical and laboratory manifestation of MPN and may result in an inappropriate interpretation of the response to treatment with tyrosine kinase inhibitors in CML patients.MethodsThe morphological, cytogenetic, and molecular genetic data from a retrospective analysis of 592 adult patients aged 18‐86 years diagnosed with CML were analyzed.ResultsIn 5 CML patients, the presence of JAK2 V617F or CALR mutation was confirmed. Three of 4 TKI‐treated patients did not reach complete hematologic response due to the persistence of thrombocytosis and/or splenomegaly. In all of them (in 3 with JAK2 V617F mutation and 1 with CALR mutation), thrombocytosis was present at the time when complete cytogenetic response was documented. In 3 out of 4 reported CML patients, thrombocytosis and/or splenomegaly were still present even at the time when deep molecular response was reached.ConclusionIn our opinion, a detailed evaluation and appropriate interpretation of clinical and laboratory data in such a category of patients seem to be extremely important, especially when a decision about the TKI change due to therapy failure is considered.
Des relations professionnelles transnationales à la négociation collective transfrontière

Published: March 2018

RésuméFace à la mondialisation, les fédérations syndicales internationales et les entreprises multinationales ont cherché à protéger leurs intérêts par des «accords‐cadres internationaux», ou ACI. En modélisant les processus de négociation sous‐jacents, les auteurs montrent que ces accords n'aboutissent que si les deux partenaires présentent une aversion pour le risque et qu'ils tendent à favoriser celle des parties chez qui cette aversion est moins prononcée, les multinationales en l'occurrence, aux dépens des travailleurs. Les choses pourraient évoluer cependant si les syndicats parviennent, par une action transnationale, à déstabiliser les multinationales en menaçant leur réputation, rapprochant le niveau d'aversion pour le risque des deux interlocuteurs.

Published: March 2018

RésuméLes auteurs analysent l'effet de la directive européenne relative à l'information et à la consultation des travailleurs sur les pratiques participatives en entreprise au Royaume‐Uni et en Irlande. Dans une analyse conceptuelle et empirique, qui fait appel à la théorie des jeux, ils formulent trois hypothèses explicatives, qu'ils cherchent à vérifier avec des données qualitatives recueillies auprès de seize entreprises. La démonstration permet de comprendre pourquoi la coopération, gage de gains mutuels, n'est pas la solution qui l'emporte dans les pays examinés, et elle nous en dit un peu plus sur l'effet des normes sur la gestion participative dans les économies de marché libérales.
Relation entre l'emploi des jeunes et l'emploi des seniors dans vingt pays de l'OCDE
Authors: JI Eun Jeong 
Published: March 2018

RésuméS'appuyant sur la thèse selon laquelle il existerait un volume fixe d'emplois dans l'économie, beaucoup de pays de l'OCDE ont cherché à lutter contre le chômage, en augmentation depuis les années 1970, par des dispositifs favorisant les cessations d'activité anticipées. Or les études à l'échelle de l'OCDE font apparaître en réalité une corrélation positive entre l'emploi des jeunes et celui des travailleurs âgés. Cependant, comme la plupart des auteurs estiment des effets moyens, on dispose de relativement peu d'informations sur l'hétérogénéité de ce lien. L'auteure tente de combler cette lacune en étudiant cette hétérogénéité dans vingt pays de l'OCDE.
Maternal Mentalization and Behavior Under Stressful Contexts: The Moderating Roles of Prematurity and Household Chaos
Authors: Yatziv Tal , Gueron‐Sela Noa , Meiri Gal , Marks Kayla , Atzaba‐Poria Naama 
Published: March 2018

This study examines the links between online maternal mentalization during mother–infant interaction, maternal sensitivity, and family triadic interaction while considering the cumulative role of two stressful contexts (cumulative stressful contexts): premature birth (a child‐driven stressful context) and household chaos (an environment‐driven stressful context). Two moderation models were tested on a sample of 134 families with 6‐month‐old infants (77 low‐risk preterm, 57 full‐term). Cumulative stressful contexts mitigated the relations between maternal mentalization and behavior, such that online maternal mentalization during mother–infant interaction was related to both maternal sensitivity and the quality of family triadic interaction under low cumulative stressful contexts, but not under high cumulative stressful contexts. Implications for understanding the influence of online maternal mentalization on maternal sensitivity and the family triad are discussed.
Impact of resilience and job involvement on turnover intention of new graduate nurses using structural equation modeling
Authors: Yu Mi , Lee Haeyoung 
Published: March 2018

AbstractAimsNurses' turnover intention is not just a result of their maladjustment to the field; it is an organizational issue. This study aimed to construct a structural model to verify the effects of new graduate nurses' work environment satisfaction, emotional labor, and burnout on their turnover intention, with consideration of resilience and job involvement, and to test the adequacy of the developed model.MethodsA cross‐sectional study and a structural equation modelling approach were used. A nationwide survey was conducted of 371 new nurses who were working in hospitals for ≤18 months between July and October, 2014.ResultsThe final model accounted for 40% of the variance in turnover intention. Emotional labor and burnout had a significant positive direct effect and an indirect effect on nurses' turnover intention. Resilience had a positive direct effect on job involvement. Job involvement had a negative direct effect on turnover intention. Resilience and job involvement mediated the effect of work environment satisfaction, emotional labor, and burnout on turnover intention.ConclusionIt is important to strengthen new graduate nurses' resilience in order to increase their job involvement and to reduce their turnover intention.
