The practice of going helps children to stop:The importance of context monitoring in inhibitory control

How do we stop ourselves during ongoing action? Recent work implies that stopping per se is easy given sufficient monitoring of contextual cues signaling the need to change action. We test key implications of this idea for improving inhibitory control. Seven- to 9-year old children practiced stopping an ongoing action, or monitoring for cues that signaled the need to go again. Both groups subsequently showed better response inhibition in a Stop-Signal task than active controls, and practice monitoring yielded a dose-response relationship. When monitoring practice was optimized to occur while children engaged in responding, the greatest benefits were observed – even greater than from practicing stopping itself. These findings demonstrate the importance of monitoring processes in developing response inhibition, and suggest promising new directions for interventions

The maximum queen’s problem with pawns

The classic n-queens problem asks for placements of just n mutually non-attacking queens on an n × n board. By adding enough pawns, we can arrange to fill roughly one-quarter of the board with mutually non-attacking queens. How many pawns do we need? We discuss that question for square boards as well as rectangular m × n boards

Race, Gender, and Leadership Promotion: The Moderating Effect of Social Dominance Orientation

The current study aims to examine the effects that applicant race and gender have on ratings of promotability for a leadership role. The current study will also investigate the role that Social Dominance Orientation, an individual difference variable that reflects attitudes towards intergroup relations being equal or not, plays in attitudes towards a candidate\u27s promotability. 213 participants were randomly assigned to one of four conditions in a 2 (candidates race: Caucasian vs. African-American) × 2 (candidates gender: male vs. female) factorial design and asked to assess the promotability of the candidate based on a brief work history and interview responses. Results suggest that candidate gender did not affect promotability ratings, and African-American candidates received significantly higher ratings than Caucasian candidates. No significant interaction of race and gender was found. Additionally, social dominance orientation was not a significant moderator of the effects of race, gender, or the interaction of race and gender

International Law Applicable to Naval Mines

This report summarizes the workshop held on February 26–27, 2014 on the law governing the use of naval mines in times of both peace and war. The workshop, organized by Chatham House, the Royal Navy and U.S. Naval War College, brought together a group of international law scholars, operational lawyers and other legal experts in the field. The objective of the workshop was to clarify existing law and identify areas of legal uncertainty to assist States to conduct their operations lawfully

Measuring Academic Achievement of University of Kentucky Student Athletes: Helping the Center for Academic and Tutorial Services Better Allocate Resources

The NCAA requires its member institutions and student athletes to maintain certain academic requirements to remain eligible for competition. To ensure academic success, many institutions establish academic centers for their student athletes. The University of Kentucky was the first institution to develop a facility of this type. The Center for Academic and Tutorial Services (CATS) provides academic enhancement for its student athletes. After a brief overview on current NCAA academic eligibility requirements, this paper looks at the organization of CATS and at the current literature on student athlete academic achievement. Then a few analyses were conducted on the academic achievement of the 2008 freshman student athletes by sport and the effects of the student athlete to counselor ratio on academic performance controlling for gender, incoming test scores, athletic aide, and season of sport. It found significant differences of academic achievement for certain sports at UK and a negative relationship between the student athlete to counselor ratio and academic achievement. Finally, the paper recommends a few ways to improve services for student athletes at CATS. These recommendations include reducing student athlete/counselor ratio, redistributing additional job responsibilities for counselors, and collecting measurable data to improve services in the future

Diameter-separation of chessboard graphs

We define the queens (resp., rooks) diameter-separation number to be the minimum number of pawns for which some placement of those pawns on an n×n board produces a board with a queens graph (resp., rooks graph) with a desired diameter d. We determine these numbers for some small values of d
