The current study (N = 120) provides a more nuanced understanding of individual and collective responses to social disadvantage by examining the ways in which women anticipate responding to ‘daily sexism’. We test how responses are independently related to ingroup identification, disidentification, and perceived ingroup homogeneity. Results show that women favor confronting sexism over inaction, even if that involves disparaging the ingroup. Specifically, women expect to engage in both individual and collective strategies in response to a sexist statement. Identification with women was positively associated with both collective and individual (non-group disparaging) responses, but only collective responses related to broader intentions to engage in collective action for social change. Finally, perceived group homogeneity uniquely increased agreement with the sexist statement, endorsement of inaction, and group-disparaging responses. Theoretical and practical implications are discussed.German Research FoundationPortuguese Foundation for Science and Technolog

Exploring the potential of the cost-efficient tahmo observation data for hydro-meteorological applications in sub-saharan africa

The Trans-African Hydro-Meteorological Observatory (TAHMO) is a promising initiative aiming to install 20,000 stations in sub-Saharan Africa counteracting the decreasing trend of available measuring stations. To achieve this goal, it is particularly important that the installed weather stations are cost-efficient, appropriate for African conditions, and reliably measure the most important variables for hydro-meteorological applications. Since there exist no performance studies of TAHMO stations while operating in Africa, it is necessary to investigate their performance under different climate conditions. This study provides a first analysis of the performance of 10 selected TAHMO stations across Burkina Faso (BF). More specifically, the analysis consists of missing value statistics, plausibility tests of temperature (minimum, maximum) and precipitation, spatial dependencies (correlograms) by comparison with daily observations from synoptical stations of the BF meteorological service as well as cross-comparison between the TAHMO stations. Based on the results of this study for BF for the period from May 2017 to December 2020, it is concluded that TAHMO potentially offers a reliable and cost-efficient solution for applications in hydro-meteorology. The usage of wind speed measurements cannot be recommended without reservation, at least not without bias correcting of the data. The limited measurement period of TAHMO still prevents its usability in climate (impact) research. It is also stressed that TAHMO cannot replace existing observation networks operated by the local meteorological services, but it can be a complement and has great potential for detailed spatial analyses. Since restricted to BF in this analysis, more evaluation studies of TAHMO are needed considering different environmental and climate conditions across SSA

Effects of Magnetic Field on Josephson Current in SNS System

The effect of a magnetic field on Josephson current has been studied for a superconductor/normal-metal/superconductor (SNS) system, where N is a two-dimensional electron gas in a confining potential. It is found that the dependence of Josephson currents on the magnetic field are sensitive to the width of the normal metal. If the normal metal is wide and contains many channels (subbands), the current on a weak magnetic field shows a dependence similar to a Fraunhofer-pattern in SIS system and, as the field gets strong, it shows another type of oscillatory dependence on the field resulting from the Aharonov-Bohm interference between the edge states. As the number of channels decreases (i.e. normal metal gets narrower), however, the dependence in the region of the weak field deviates from a clear Fraunhofer pattern and the amplitude of the oscillatory dependence in the region of the strong field is reduced.Comment: 14 pages, 9 figure

Assessment of ractopamine in meat and bone meal through LC-MS/MS using solid phase extraction (SPE).

Ractopamine (RCT) used as feed additive acts metabolically to decrease fat content contributing to a lean carcass. However, RCT is not broadly accepted worldwide but limited to stringent rules imposed by some countries. To assure human consumption safety, governments are encouraging research institutions to develop sensitive methods to accurately detect and quantify RCT. Yet, little is known about RCT concentration in raw materials such as meat and bone meal (MBM). The effectiveness of a previously developed method for RCT analysis was tested to determine sources of RCT contamination in MBM and discern from potential overestimation in feed
