Board composition, process, and activism: evidence within American firms

This study provided an empirical test of the effects of compositional and process variables on board activism. The attributes examined were functional area knowledge, independence, duality, and effort norms. The findings from this study provided support for the positive relationships between both functional area knowledge and effort norms and board activism. The strong relationship between effort norms and activism indicates the importance of process variables in board research and the need for additional research using process variables in a board context giving further insight into board activism and governance. Additionally, the relationship between functional area knowledge and board activism highlights how boards ability to meet cognitive demands is critical in board performance. These results as well as future research directions are examined in the discussion.board activism, board governance, board attributes, strategic management.

Roommate Relationships: A Comparison of Interracial and Same-Race Living Situations

The effects of same-race versus interracial dormitory roommate relationships were explored with regard to relationship dissolution and academic achievement (i.e., grade point average). The present investigation made use of archival data spanning two academic years at a large, relatively diverse university. Of primary interest were White and African American first-year students assigned to White or African American roommates upon their arrival on campus. Another factor that was incorporated into this analysis was whether students requested to live with their roommates or were randomly assigned. Interracial roommate relationships were more likely to dissolve than either same-race White or same-race African American relationships. Randomly assigned living situations were less successful than ones in which roommates requested to share a room. Concerning grade point average at the end of the first academic quarter, African American first-year students tended to do better in interracial living situations, whereas White first-year students' academic success was not affected by roommate race. Instead, White first-year students were more sensitive to the academic abilities of their roommates. Results are discussed with regard to the implications for intergroup contact

Remote profiling of lake ice thickness using a short pulse radar system aboard a C-47 aircraft

Design and operation of short pulse radar systems for use in ice thickness measurement are described. Two ice profiling systems were tested, an S system which used either random noise or continous wave modulation at 2.8 GHz and a less powerful C band system which operated at 6.0 GHz and did not have random noise modulation. Flight altitudes of 4,000 feet were used, but the S band system was usable at 7,000 feet allowing flights in poor weather conditions. A minimum ice thickness of four inches is required for measurement, while the thickest ice measured was 36 inches. System accuracy is plus or minus one inch

Evaluating High School Students’ Constitutional and Civic Literacy: A Case Study of the Washington, DC Chapter of the Marshall-Brennan Constitutional Literacy Project

The United States maintains a reputation as a vibrant, participatory democracy. Yet, paradoxically, formal civics education has essentially disappeared from America’s public high schools, particularly urban public schools serving low-income and minority students. The Marshall-Brennan Constitutional Literacy Project, which is offered at almost zero cost to public schools and districts, developed as a response to the need for civics education in high schools and as a way to train future lawyers in public speaking, leadership, and counseling. In an effort to support the growth of the Marshall-Brennan Project all over the country, the authors of this piece came together to study the Marshall-Brennan Project’s efficacy in Washington, DC during the 2010-2011 academic year. This Essay is based on a comprehensive data set of students in fifteen classes in twelve Washington, DC public and public charter schools during the 2010-2011 academic year. Students were asked substantive questions related to the curriculum, as well as their likelihood of participating in civic activities such as voting and jury service. The results indicate increased constitutional knowledge and higher likelihood of civic participation, although there is room for improvement. The Essay ends with two conclusions. First, the authors seek to inspire a subsequent, larger study of the efficacy of the Marshall-Brennan model of training law students to teach high school students about the Constitution. Second, until a larger study is conducted, the authors draw from the 2010-2011 data to suggest changes to the current model, including a greater focus on drawing connections between civic knowledge and civic action

Remote sensing study of Maumee River effects of Lake Erie

The effects of river inputs on boundary waters were studied in partial support of the task to assess the significance of river inputs into receiving waters, dispersion of pollutants, and water quality. The effects of the spring runoff of the Maumee River on Lake Erie were assessed by a combination of ship survey and remote sensing techniques. The imagery obtained from a multispectral scanner of the west basin of Lake Erie is discussed: this clearly showed the distribution of particulates throughout the covered area. This synoptic view, in addition to its qualitative value, is very useful in selecting sampling stations for shipboard in situ measurements, and for extrapolating these quantitative results throughout the area of interest

Mindfulness and engagement in COVID-19 preventive behavior

The novel coronavirus disease 2019 (COVID-19) pandemic represents a significant risk to population health. Health organizations worldwide have recommended numerous preventive health behaviors to slow the spread of COVID-19. Yet, considerable variability exists in individual-level adherence to these recommendations. Mindfulness has been associated with greater engagement in health promotive behavior (e.g., physical activity, healthy eating), and may serve as an individual difference factor that encourages adherence. However, no study to date has examined the extent to which mindfulness is associated with preventive health behaviors during a global pandemic. The purpose of the present study was to assess the relations between mindfulness and recommended preventive health behaviors for COVID-19. A national U.S. sample (N = 353; Mage = 41.47 years, range: 19–84; 50.2% female) completed an online survey via Amazon’s Mechanical Turk from April 3rd to 15th, 2020, including measures of mindfulness and frequency of avoiding touching one’s face, handwashing, disinfecting/cleaning frequently used surfaces, social distancing, and self-quarantining. Personality, health risk, and demographic factors were also assessed to test the unique association between mindfulness and preventive health behaviors. Mindfulness was significantly correlated with greater engagement in all of the COVID-19 preventive health behaviors. However, when accounting for demographics, health risk, and personality, mindfulness was only uniquely associated with engagement in social distancing. This research highlights mindfulness as an individual-level characteristic associated with engagement in COVID-19 preventive health behavior and may inform future prevention efforts aimed at improving adherence to recommendations for curbing the spread of infectious disease

A longitudinal assessment of variability in COVID-19 vaccine hesitancy and psychosocial correlates in a national United States sample

National Science Foundation [BCS-2027027]This work was supported by a RAPID grant from the National Science Foundation under Award ID BCS-2027027. The funding organization was not involved in designing the study, collecting and analyzing the data, or preparing the manuscriptRecent evidence suggests that COVID-19 vaccine hesitancy is not static. In order to develop effective vaccine uptake interventions, we need to understand the extent to which vaccine hesitancy fluctuates and identify factors associated with both between- and within-person differences in vaccine hesitancy. The goals of the current study were to assess the extent to which COVID-19 vaccine hesitancy varied at an individual level across time and to determine whether disgust sensitivity and germ aversion were associated with between- and within-person differences in COVID-19 vaccine hesitancy. A national sample of U.S. adults (N = 1025; 516 woman; M-age = 46.34 years, SDage = 16.56, range: 18 to 85 years; 72.6 % White) completed six weekly online surveys (March 20 - May 3, 2020). Between-person mean COVID-19 vaccine hesitancy rates were relatively stable across the six-week period (range: 38-42 %). However, there was considerable within-person variability in COVID-19 vaccine hesitancy. Approximately, 40 % of the sample changed their vaccine hesitancy at least once during the six weeks. There was a significant between-person effect for disgust sensitivity, such that greater disgust sensitivity was associated with a lower likelihood of COVID-19 vaccine hesitance. There was also a significant within-person effect for germ aversion. Participants who experienced greater germ aversion for a given week relative to their own six week average were less likely to be COVID-19 vaccine hesitant that week relative to their own six-week average. This study provides important information on rapidly changing individual variability in COVID-19 vaccine hesitancy on a weekly basis, which should be taken into consideration with any efforts to decrease vaccine hesitancy and increase vaccine uptake. Further, these findings identify-two psychological factors (disgust sensitivity and germ aversion) with malleable components that could be leveraged in developing vaccine uptake interventions.WOS:0009467190000012-s2.0-8514785927036669969Science Citation Index ExpandedarticleUluslararası işbirliği ile yapılan - EVETŞubat2023YÖK - 2022-2

Coordinated aircraft and ship surveys for determining impact of river inputs on great lakes waters. Remote sensing results

The remote sensing results of aircraft and ship surveys for determining the impact of river effluents on Great Lakes waters are presented. Aircraft multi-spectral scanner data were acquired throughout the spring and early summer of 1976 at five locations: the West Basin of Lake Erie, Genesee River - Lake Ontario, Menomonee River - Lake Michigan, Grand River - Lake Michigan, and Nemadji River - Lake Superior. Multispectral scanner data and ship surface sample data are correlated resulting in 40 contour plots showing large-scale distributions of parameters such as total suspended solids, turbidity, Secchi depth, nutrients, salts, and dissolved oxygen. The imagery and data analysis are used to determine the transport and dispersion of materials from the river discharges, especially during spring runoff events, and to evaluate the relative effects of river input, resuspension, and shore erosion. Twenty-five LANDSAT satellite images of the study sites are also included in the analysis. Examples of the use of remote sensing data in quantitatively estimating total particulate loading in determining water types, in assessing transport across international boundaries, and in supporting numerical current modeling are included. The importance of coordination of aircraft and ship lake surveys is discussed, including the use of telefacsimile for the transmission of imagery
