Purpose: This study builds a stochastic model of a discrete-time Markov chain (DTMC) that fits well with a dataset of professional playing records. Methods: The point-by-point dataset of Men's single matches played in the Association of Tennis Professionals (ATP) tour from 2011 to 2015 is analyzed. A long-debated assumption on the…

African American males have been overrepresented in the prison system in the United States since the 1970s. This comprehensive survey examines the influence of the prison reentry program on the lives of African American males after they are released from jail and prison in the United States. Jail is a place of confinement for persons held in…

Because of the high cost, venue-based probability sampling of young men who have sex with men (YMSM) is largely inaccessible to social researchers. The aim of this study is to compare the feasibility of implementing geosocial networking application-based (GSNA) and venue-based probability sampling of young men who have sex with men. A…

This study investigates to what extent differences in ability and effort attributions can explain students' reluctance to reorient after failure in the first year at the university. Reluctance to reorient after failure increases the likelihood of drop out. The empirical investigation is based on a sample of fulltime first-entry bachelor students…

In this article, we outline several activities revolving around soccer players who participated in the 2018 FIFA World Cup and 2019 FIFA Women's World Cup. Classroom activities are described from different perspectives, useful for a range of different statistics courses. In a first semester probability theory course, students investigate the…

Children of color are disproportionately referred for discipline in schools and subsequently receive harsher punishments than their peers. Teachers' implicit bias has been identified as a possible source of these disparities, particularly for Black boys. However, teachers' social--emotional competence (SEC) may mitigate biased responses to Black…

This study extends prior work on the college-going efforts of Latino boys and adolescents (Latinos) by examining the extent to which meeting with a school counselor is related to their college-going aspirations and whether they apply to and ultimately matriculate to college. The study utilizes social capital and social reproduction theories to…

Limited information is available concerning the specificity of the forms and functions of aggressive behavior exhibited by boys with fragile X syndrome (FXS). To investigate these relationships, we conducted indirect functional assessments of aggressive behavior exhibited by 41 adolescent boys with FXS and 59 age and symptom-matched controls with…

Using a vignette methodology, we examined college students' likelihood of "no-showing" for a hypothetical initial appointment for counseling. Participants in a low level of distress condition were less likely to attend their appointment as compared to those in a high distress condition. Knowing they would see a male therapist and not…

Despite the evidence implicating implicit racial bias in teacher decision-making as one reason for the overrepresentation of Black male students in school discipline practices, there is minimal research regarding interventions that address implicit racial bias in the school setting. A System 2 cue refers to a behavioral cue that engages more…

We recorded visual event-related brain potentials from 32 adult male participants (16 high-functioning participants diagnosed with autism spectrum disorder (ASD) and 16 control participants, ranging in age from 18 to 53 years) during a three-stimulus oddball paradigm. Target and non-target stimulus probability was varied across three probability…

Baltimore City Public Schools' school-based mental health program sought to reduce barriers to treatment for students by providing on-site mental health care. This study examines differences in treatment attendance, dropout, and pharmacologic referral among students enrolled in the Johns Hopkins affiliated program. Enrolled student records for…

Few empirical studies exist to guide researchers in determining the number of focus groups necessary for a research study. The analyses described here provide foundational evidence to help researchers in this regard. We conducted a thematic analysis of 40 focus groups on health-seeking behaviors of African American men in Durham, North Carolina.…

The negative consequences associated with out-of-school suspension (OSS) are widely recognized, yet its commonly utilized counterpart, in-school suspension (ISS), has received little attention. This study examined school and student characteristics that predicted ISS and its links to academic outcomes, using the nationally representative High…

The purpose of this quantitative study was to investigate the possible relationships between teacher characteristics and their decisions to recommend placement of African American male students for special education. The teacher characteristics (gender, race, age, years of teaching service, self-efficacy and teacher expectations) were the…
