Mean girls, queen bees and iron maidens? Female leadership and accusations of workplace bullying
(2022-10-11)
We examined whether female leaders would be evaluated less favorably compared to male leaders regarding workplace bullying. Previous research has demonstrated that women violating prescriptive gender norms of communality experience backlash, and that female leaders are stereotyped of having a communality deficit. Building on that, we hypothesized (1) more moral outrage against and (2) more intentions to punish a female leader compared to a male leader. We further hypothesized (3) the accusations of ...

The combined application of nitrogen and biochar reduced microbial carbon limitation in irrigated soils of West African urban horticulture
(2022-07-16)
Background:
Intensive wastewater irrigated urban horticulture in sub-Saharan West Africa receives high nutrient inputs, which lead to large gaseous and leaching losses. The addition of biochar to the usually sandy soils may reduce these losses and improve the habitat conditions for soil microorganisms. Two similar experiments focused on crop yields and nutrient balances have been carried out over a 2-year period in semi-arid Ouagadougou, Burkina Faso, and in sub-humid Tamale, Ghana, representing to some extent ...

Management Effect on the Weed Control Efficiency in Double Cropping Systems
(2023-02-04)
There are often negative side-effects associated with the traditional (silage) maize cropping system related to the unprotected soil surface. Reducing soil disturbance could enhance system sustainability. Yet, increased weed pressure and decreased nitrogen availability, particularly in organic agriculture, may limit the implementation of alternative management methods. Therefore, a field experiment was conducted at two distinct locations to evaluate the weed control efficiency of 18 organically managed silage maize ...

Lanthanide Complexes (Ln=La, Nd, Dy) of Octaethyl propane-1,1,3,3-tetrayltetrakis(phosphonate): Multidentate Binding Competing with Monodentate DMSO Complexes
(2022-12-09)
The preparation of lanthanide nitrate complexes [Ln(NO₃)₃{L}]ₙ (Ln³+=La, Nd, Dy) supported by the octaethyl propane-1,1,3,3-tetrayltetrakis(phosphonate) (L) chelate ligand platform is presented. Re-crystallization of these compounds from DMSO/THF led to a complete replacement of the multidentate phosphonate ester ligand and the formation of exclusively DMSO-supported lanthanide nitrate species [Ln(NO₃)₃(DMSO)₄]. The relative basicity of a model phosphonate ester vs. DMSO is explored with theoretical means, pointing ...

Family as a redistributive principle of welfare states: An international comparison
(2022-08-03)
Redistribution is one of the main characteristics of the welfare state, and welfare state research has dealt intensely with various facets of it. The main focus in analysing redistribution is on the redistributive logics of welfare states in terms of work-related rights. Family as a major principle of welfare state redistribution, though, has hardly been included in these welfare state analyses. It has mainly been addressed by analysing outcome data or by analysing care as the most relevant characteristic of the ...

Far-Right Local Governments and Civil Society: Findings from France and Italy
(2022-03-02)
The rise of far-right parties across Europe and their entrance into government at the local, if not regional or national, levels pose challenges for established civil society actors. This article draws on early findings from an ongoing research project in order to present two case studies of far-right local governments in small industrial towns in France and Italy: Hayange and Sant’Agata Bolognese. Keying in on these local administrations’ approaches to civil society and drawing on semi-structured interviews with ...

Effects of Sodium Salinity on Rice (Oryza sativa L.) Cultivation: A Review
(2023-01-17)
Sodium salinity negatively affects and reduces yields in international agricultural systems. This stress decreases crop growth and development, causing tissue death, flowering abortion, and senescence of the fertilized embryo, and negatively affects enzymatic activity, protein synthesis, among other processes. Rice is a cereal of great international demand for its nutritional properties and its productivity is affected by the presence of salts in agricultural surfaces. The objective of this article is to review the ...

Growth of C-S-H phases on different metallic surfaces
(2022-02-21)
The influence of reinforcement, especially fibre reinforcement in ultra-high performance concrete is strongly dependent on the bonding (adhesive, shear and friction bond) between metallic surface and cementitious matrix. As usually straight fibres are used for fibre reinforcement and, thus, no significant mechanical bonding is existent, the adhesive bond is particularly important. Previous studies stated that the adhesive bonding behaviour between metallic materials and cementitious matrix strongly depends on the ...

The ‘forma specialis’ issue in Fusarium: A case study in Fusarium solani f. sp. pisi
(2018-01-19)
The Fusarium solani species complex (FSSC) has been studied intensively but its association with legumes, particularly under European agro-climatic conditions, is still poorly understood. In the present study, we investigated phylogenetic relationships and aggressiveness of 79 isolates of the FSSC collected from pea, subterranean clover, white clover and winter vetch grown under diverse agro-climatic and soil conditions within Temperate and Mediterranean Europe. The isolates were characterized by sequencing tef1 and ...

Roots of symptom-free leguminous cover crop and living mulch species harbor diverse Fusarium communities that show highly variable aggressiveness on pea (Pisum sativum)
(2018-02-14)
Leguminous cover crop and living mulch species show not only great potential for providing multiple beneficial services to agro-ecosystems, but may also present pathological risks for other crops in rotations through shared pathogens, especially those of the genus Fusarium. Disease severity on roots of subterranean clover, white clover, winter and summer vetch grown as cover crop and living mulch species across five European sites as well as the frequency, distribution and aggressiveness to pea of Fusarium spp. ...
