Toward Value Co-Creation: Increasing Women’s Presence in Management Positions through Competition against a Set Target
2017
Despite empirical evidence that women’s presence in management positions is a source of value co-creation for firms, these positions are still male-dominated. Some evidence from experimental economics suggests that one reason for this imbalance is that women shy away from competition. However, most of these studies have focused on competition systems that pit individuals against each other. We present an economic laboratory experiment that compares competition against others with competition against a set target. The crucial difference is that whereas the former involves competing against opponents, the latter does not. Our results show that significantly more women are willing to compete a…
Sexism and Aggression in Adolescence.¿How Do They Relate to Perceived Academic Achievement?
2018
Sexist attitudes are rooted in patriarchal structures, which uphold traditional gender stereotypes, and which are still found in society today. Scholars have found gender differences in perceived academic achievement, with girls performing better than boys, and negative relationships between sexism and perceived academic achievement. Moreover, perceived academic achievement and sexist attitudes have been associated with aggression and different kinds of violence. This study examined the associations between sexist attitudes and perceived academic achievement (using self-report data). The study also assessed the mediating role of physical and verbal aggression in the relationship between sex…
A Comparative Analysis of the Social Performance of Global and Local Berry Supply Chains
2016
The goal of this paper is twofold: to comparatively analyze the social performance of global and local berry supply chains and to explore the ways in which the social dimension is embedded in the overall performance of food supply chains. To achieve this goal, the social performance of five global and local food supply chains in two countries are analyzed: wild blueberry supply chains in Latvia and cultivated raspberry supply chains in Serbia. The study addresses two research questions: (1) What is the social performance of the local and global supply chains? (2) How can references to context help improve understanding of the social dimension and social performance of food supply chains? To…
Pois, fèverole, lupin, soja pour l’alimentation humaine : quelle place dans la littérature scientifique mondiale ?
2018
Malgré un élan positif mondial favorisant la consommation des légumineuses, le contexte français restecompliqué avec une crise de la production et une fermeture de marchés historiques, bien qu’opportunistes,en alimentation humaine. L’interprofession Terres Univia a souhaité mieux caractériser les connaissancesscientifiques mondiales concernant le débouché alimentation humaine pour ces graines.Terres Univia a donc mené le projet BIPROL en collaboration avec l’INRA et Orchidali dans le but d’évaluerles niveaux de connaissance et d’identifier les sujets investis et émergeants sur le pois, le lupin, la fèverole etle soja, légumineuses les plus cultivées en France, pour une utilisation en alimen…
Indexations et diffusions internationales de Synergies Algérie, revue du Gerflint : état des lieux en 2018
2018
Toute étude prenant pour objet la revue Synergies Algérie place auteurs, chercheurs et lecteurs dans l’un des centres les plus productifs de la francophonie scientifique internationale en sciences humaines et sociales. Le nombre élevé et la diversité de ses indexations depuis sa fondation en 2007 ainsi que la qualité de la diffusion de ses articles en témoignent. À la frontière éditoriale entre le 26e numéro et le 27e , cette contribution offre un bilan de ces reconnaissances et de cette visibilité désormais inscrites dans la durée, permettant d’envisager un avenir prometteur. La d&…
Willingness to Adopt Biochar in Agriculture: The Producer’s Perspective
2017
Most research on biochar has focused either on the mechanistic or the biophysical aspects, and there has been relatively little research into the social applicability and acceptance of biochar as a soil enhancer in agriculture. However, whether to adopt biochar in their practice is ultimately the farmers’ decision, and their willingness to do so is crucial. Here, we show the producer’s perspective on adopting biochar, using Polish farmers as a case study. Poland is an interesting case study because biochar has only recently attracted the attention of researchers, entrepreneurs, and other stakeholders there. We performed standardized, semi-structured interviews with 161 Polish farmers to eva…
UCT-MBR vs IFAS-UCT-MBR for Wastewater Treatment: A Comprehensive Comparison Including N2O Emission
2017
In this study the performance (in terms of carbon and nutrient removal) and N2O emission of two plant configurations adopting innovative technologies were investigated. With this regards, an University Cape Town (UCT) membrane bioreactor (MBR) plant and an Integrated Fixed Film Activated Sludge (IFAS) -UCT-MBR plant were monitored. Both plants treat real wastewater under two different values of the influent carbon nitrogen ratio (C/N = 5 mgCOD/mgN and C/N = 10 mgCOD/mgN). Results have shown the highest carbon and nutrients removal efficiencies for the IFAS-UCT-MBR configuration during both the two investigated C/N values. Furthermore, the lowest N2O emission occurred for the IFAS-UCT-MBR.
Identifying a marine microalgae with high carbohydrate productivities under stress and potential for efficient flocculation
2018
Microalgal biomass represents a potential third generation feedstock that could be utilised as a source of carbohydrates for fermentative production of a range of platform biochemicals. Identifying microalgal strains with high biomass and carbohydrate productivities while also being amenable to downstream processes is key in improving the feasibility of these processes. Utilising marine microalgae capable of growing in seawater will decrease reliance on freshwater resources and improve the sustainability of production. This study screened several marine microalgae believed to accumulate carbohydrates to find new high performing strains. Four strains had high growth rates and accumulated car…
An environmental study by factor analysis of surface seawaters in the Gulf of Valencia (Western Mediterranean)
1999
Abstract A study is made on the quality of coastal waters in the Gulf of Valencia (Spain) in terms of contamination markers including microbiological agents, toxic heavy metals and nutrients that adversely affect the environment. Relationships are also established between these factors and other physical and chemical parameters. A multivariate analysis is conducted where a total of 14 parameters are established for 919 water samples corresponding to 52 sampling points along the coast of the province of Valencia – specifically, total and fecal coliforms, fecal streptococci, Ni(II), Zn(II), Pb(II), Cd(II), Cu(II) and Cr(VI) concentrations, nitrates, phosphates, dissolved oxygen and finally pH…
E-government in Tanzania: Current Status and Future Challenges
2012
Article from the book: Electronic Government. Also available from SpringerLink: http://dx.doi.org/10.1007/978-3-642-33489-4_17 The public sector plays an important role in the economic growth and development of developing countries. The application of modern Information and Communication Technologies (ICT) may help improve the public sector by contributing to new services and processes that address citizens as well as government-to-government services, involve citizens more directly in decisions being made, and contribute to streamlining work processes and standardizations needed to develop a well-functioning public sector. Research focusing on E-government in developing countries is still …
