From the abstract: "This study investigates the influence of nonfinancial 8-K disclosures released during the earnings announcement window on the abnormal trading activities of individual investors. Our results reveal that individual investors exhibit higher levels of abnormal trading activities when firms release nonfinancial 8-Ks during the (0,1) window of earnings announcements.
From the abstract: There is a gap in research that examines how professional learning communities have been structured to support Black men teachers and how teachers have responded to these efforts. This article explores one national teacher union's implementation of a weekly professional development series for early career Black men in-service teachers in one Southern state. Based on semi-structured interviews with Black men teacher participants and facilitators as well as an analysis of the video of virtual coaching sessions, we found that the national teacher union's professional learning community was attentive to Black men teachers' social and emotional needs.

Feminist approaches to environmental politics. Contemporary Political Theory.
From the intro: Ecofeminism as scholarship and practice continues to polarize, draw criticism, and inspire scholarly works and politics that account for the structures of domination that perpetuate sexism and ecological exploitation. Ecofeminist scholarship grew in volume and prominence in the 1970s and 1980s but began to falter under the weight of critiques that the approach upheld gender essentialism and a white western feminism that does not account for the needs, views, politics, and orientations to the planet outside of the global north. And yet, ecofeminism still holds relevance and offers significant perspectives and tools that can respond to these important criticisms and offer key insights in the ongoing efforts to address climate change and environmental and gender injustices. As a conversation among scholars working in ecofeminist political thought, this Critical Exchange asks about the contemporary relevance of this tradition to their approach as scholars, inside and outside of the academy.

The effects of different exercise modalities on visuospatial working memory in healthy young adults. Journal of Human Sport and Exercise,
19(4), 1084–1094.
This study was to differentiate the acute effects of random motor skill practice and acute cardiovascular exercise on the task performance in visuospatial working memory (VSWM). 24 healthy adults with no golf experience were randomized into random motor skill practice (i.e., golf putting task) and acute cardiovascular exercise (i.e., 64% and 76 % of predicted maxi-mum heart rate) groups. Pre-test and post-test were administered for two VSWM tasks (i.e., memory matrix and rotation matrix). The performance of VSWM was improved immediately after the acute intervention. However, the improvement in retention effect was not maintained. In addition, no group differences were noted between random motor skill practice and acute cardiovascular exercise during post-test. The findings suggested the temporal effects of acute intervention. There is need to add a true control group for further research with larger sample size to examine the role of exercise modalities between acute intervention and executive function.
