Potential combined effects of maternal smoking and coffee intake on foetal death within the Danish National Birth Cohort
2018
Background: Several studies have linked coffee intake and smoking to foetal death, but a possible interaction between both exposures remains unknown.Methods: We studied, within the Danish National Birth Cohort, the potential interaction between smoking and coffee drinking while pregnant on the risk of foetal (early and late) death. The study included 90 086 pregnant women, with information about their smoking habit and coffee intake in early pregnancy, and several potential confounding factors. Interaction was studied by calculating both the hazard ratio (HR) in Cox's regression (linear and smoothed restricted cubic spline) and the interaction contrast ratio (ICR).Results: Women who neither…
Refining the preconditions of a social licence to operate (SLO) : reflections on citizens’ attitudes towards mining in two Finnish regions
2016
The debate around the social licence to operate (SLO) has been lively in recent years. In its elementary forms, the SLO is interpreted as the social acceptance granted by a community to mineral exploration and mining activities. Our theoretical assumption is that the SLO as a concept is both case-specific and more general, contingent, among other things, upon public opinion. In this study, acceptance is considered as general and anticipatory in the sense that it can act as a precondition for individual SLOs. Our intention is to contribute especially to recent novel research focusing on the more general background and factors contributing to the SLO. Using survey data (N = 1064), we explore …
Social engagement from childhood to middle age and the effect of childhood socio-economic status on middle age social engagement: results from the Na…
2016
ABSTRACTSocial engagement has powerful effects on wellbeing, but variation in individual engagement throughout the lifecourse is wide. The trajectories may differ by gender and be affected by socio-economic status (SES). However, long-term development of social engagement is little studied and the effect of childhood SES on later-life social engagement remains obscure. We aimed to describe the social engagement development from childhood to middle age by gender and test the effect of childhood SES on middle age social engagement. Data (N=16,440, 51.3% male) are drawn from the on-going National Child Development Study, following British babies born in 1958. Social engagement was measured by …
Lithium-ion batteries for electric vehicles: combining Environmental and Social Life Cycle Assessments
2018
Electric vehicles (xEV) are a key low carbon technology for mobility. Although xEV have no tailpipe emissions, the production of traction batteries leads to environmental and social burdens. In this context, authors assess the environmental and social impacts of a cell of Lithium ion traction battery in order to identify the most relevant aspects and the potential added value of performing both the assessments. Results show the relevance of the resources in terms of both environmental and social impacts. Moreover, the social assessment results pointed out the relevance of the geographical boundaries, often overlooked for in the environmental analysis. The combination of both the assessment …
Les responsables de résidences très sociales : des professionnels tiraillés entre différents cadres d’appréhension de la réalité
2022
Cet article porte sur les responsables de résidences très sociales, entendons des responsables de structures locatives destinées à des individus et familles très modestes qui ne sont pas intégrés dans le logement social « traditionnel ». Le propos souligne les tensions relatives au métier en dégageant plus précisément divers formats et cadres d’appréhension de la réalité dans lesquels les agents de terrain ici concernés sont engagés d’une façon ou d’une autre. Ce faisant, il s’agit d’identifier diverses formes de contrôle (gestionnaire, discrétionnaire, sécuritaire...) qui ponctuent les journées de professionnels à la fois proches et éloignés aussi bien de « leurs » résidents que de leur in…
Between-group competition and human cooperation.
2008
A distinctive feature of human behaviour is the widespread occurrence of cooperation among unrelated individuals. Explaining the maintenance of costly within-group cooperation is a challenge because the incentive to free ride on the efforts of other group members is expected to lead to decay of cooperation. However, the costs of cooperation can be diminished or overcome when there is competition at a higher level of organizational hierarchy. Here we show that competition between groups resolves the paradigmatic ‘public goods’ social dilemma and increases within-group cooperation and overall productivity. Further, group competition intensifies the moral emotions of anger and guilt associated…
The use of TikTok in Initial Teacher Training
2023
The continuous evolution of technology and the increasingly massive use of visual content have given way to an era characterized by the use of short videos mainly through social media. Among these applications, TikTok has been chosen primarily by young people thanks to the unique communication strategies it offers. This paper presents the activities that have involved and will involve first-year students enrolled in the single-cycle master’s degree course in Primary Education Sciences of the University of Palermo in the a.y. 2022/2023. This study aims primarily at investigating the perceptions that university students have regarding the use of TikTok to implement learning and to highlight t…
Foreign Language Pre-Service Teachers’ Attitudes Towards Integrated Technology
2020
The COVID-19 pandemic worldwide evidenced the need to revise and strengthen the current perspective of the role of technology in non-technology-based classes. The current situation requires the revision of practices and basic knowledge of computer literacy and use. Traditionally, technology in the process of language learning has been considered anecdotical. As a result, many teachers do not have the necessary skills to implement proper technology-supported classes. Being that the case at Universidad de Alcalá (Spain), we looked at the students’ needs in integrating a number of different applications in the classroom in order to provide them with additional technological skills. Twenty-two …

Social Determinants of Success: Social Media, Corporate Governance and Revenue
2019
This study examined how social media (Twitter and LinkedIn) relates to the operating revenue by investigating the effect of the use of social media by the board of directors. To tackle this question, we analyzed the mediating and moderating relationship of social media on the effect of board size in operating revenue (turnover). We studied the implications of the use of social media by the board members by using structural equation modeling (SEM). The data consisted of a random sample of 100 companies listed on the NASDAQ. The study makes two main contributions. First, it shows interesting differences in the use of social media for the operating revenue. Our results suggest that while Twitt…
