Number of Replications Required in Control Chart Monte Carlo Simulation Studies

Monte Carlo simulations have been used extensively in studying the performance of control charts. Researchers have used various numbers of replications in their studies, but almost none of them provided justifications for the number of replications used. Currently, there are no empirically based recommendations regarding the required number of replications to ensure accurate results. This research examined six recently published studies to develop recommendations for the minimum number of replications necessary to reproduce the reported results within a specified degree of accuracy. The results of this study indicated that using 10,000 replications was unnecessarily large and a smaller number of replications could be used to reproduce the target ARLs within the 2% error bands satisfying the modified Mundfrom's criteria. In many cases, only 5,000 replications or fewer were required. In general, the number of replications required to reproduce the target ARL decreased as the shift size increased. In addition, the results of this study provide general recommendations for the required number of replications to use in future SPC simulation studies.     

Resolving complex community problems: Applying collective leadership and Kotter's change model to wicked problems within social system networks

How does collective leadership within social networks resolve chronic and complex problems common to communities? Unfortunately, sometimes it does not, but when it does, the outcome may be truly extraordinary. We use a case study approach to explain how one Midwest community within the USA applied collective leadership within a community network to reduce teen births. It took ten years of what many identified as provocative media campaigns and comprehensive sex education programs to reduce teen births by 65%, significantly exceeding the stated goal. Using Kotter's change model as a backdrop, powerful strategies and provocative creativity reveal courageous leadership within a social network of diverse people and organizations focused on improving the social well being of their community.     

Cultivating students’ reflective capacity through group-based mindfulness instruction

ABSTRACT

Cultivating critically reflective practitioners is a vital professional competency for social work students. However, few reflective models support undergraduate students to foster nonconceptual skills important to developing reflective capacity. This article presents a group-taught mindfulness teaching intervention applied in a professional practice course to facilitate reflective capacity of social work students preparing for their first placement. Trial data derived from pre–post course administration of the Five Facet Mindfulness Questionnaire show significant gains in awareness were produced on two of the questionnaires’ five mindfulness facets of describe and nonjudgment. A developmental model detailing these shifts and its implications for group-based learning is outlined.     

Field Note—From MSW to J-O-B: Using Field Seminar to Prepare Students for Employment

ABSTRACT

Social work field education is expected to help students transition from the classroom to the practice setting. Yet, few social work programs adequately provide career development support to increase students’ employability. This Field Note presents practical, relevant and immediate strategies for implementing the MSW to J-O-B curriculum innovation in the field practicum seminar. The purpose is to help students clarify professional goals and successfully obtain employment or career advancement opportunities following graduation. Formative evaluation results for this professional development curriculum are presented.     

Heritage and Community Regeneration in Northern Ireland: Finding Points of Coalescence in the Development Planning Process

ABSTRACT

Bringing heritage resources to the forefront in communities can serve to help heal long-standing divides with impacts not only in economic dimensions, but also social and cultural. It is an ironic turn—some of the heritage resources in Northern Ireland have been the site of intense and violent conflict over long periods of time—and now serve as focal points for bringing together divergent groups, helping heal divisions in communities. Seventeen communities throughout Northern Ireland are examined, gauging impacts and perceptions of community regeneration and redevelopment processes. Results provide insights for addressing lingering conflict and finding points of coalescence, with heritage playing a role in transformation.     

Childhood Sexual Experiences and Adult Health Sequelae Among Gay and Bisexual Men: Defining Childhood Sexual Abuse

Gay and bisexual men carry the burden of HIV infections in the United States and have high rates of childhood sexual abuse that predict HIV and other health outcomes. This study examined differential effects of forced, consensual, and no childhood sexual experiences (CSE) on health outcomes among a probability sample of adult men who have sex with men (MSM). The forced sex group had the highest levels of psychological distress, substance use, and HIV risk. There were no differences in rates of depression and suicidal ideation between the consensual- and no-sex groups. The consensual- and forced-sex groups had higher rates of substance use and transmission risk than the no-sex group. The forced-sex group, however, had significantly higher rates of frequent drug use and high-risk sex than the consensual group. Findings suggest that forced CSEs result in a higher-risk profile than consensual or no childhood sexual experiences, the kind of risk pattern differs between forced and consensual childhood sexual experiences, and the underlying mechanisms that maintain risk patterns may vary. It is important to clarify risk patterns and mechanisms that maintain them differentially for forced and consensual sex groups so that interventions may be tailored to the specific trajectories related to each experience.     

Internet Sex Ads for MSM and Partner Selection Criteria: The Potency of Race/Ethnicity Online

The explosive growth in Internet use by men who have sex with men (MSM) to find sexual partners has been noted in the research literature. However, little attention has been given to the impact of participating in this online sexual marketplace for MSM of color, despite race and ethnicity as frequently used selection criterion in personal ads or profiles. Six focus group discussions (n = 50) and 35 in-depth qualitative interviews were conducted with African American, Latino, or Asian and Pacific Islander MSM in Los Angeles, which included discussion of their use of Internet sites to meet or interact with other MSM. Men reported race and ethnicity as a pervasive and powerful factor in facilitating or derailing Internet-mediated sexual encounters. The racialized interactions that MSM of color reported ranged from simple expressions of race-based preferences, to blatantly discriminatory or hostile interactions, and often demeaning race-based sexual objectification. Experiences of rejection and a perceived hierarchy of value in the sexual market based on race had definite costs for these MSM using these online sites. Furthermore, the private and solitary nature of seeking partners online meant that there was little to buffer the corrosive aspects of those negative experiences. These online dynamics have implications for the power balance in Internet-mediated sexual liaisons, including sexual decision making and sexual risk.     

A Two-Question Method for Assessing Gender Categories in the Social and Medical Sciences

Three studies (N = 990) assessed the statistical reliability of two methods of determining gender identity that can capture transgender spectrum identities (i.e., current gender identities different from birth-assigned gender categories). Study 1 evaluated a single question with four response options (female, male, transgender, other) on university students. The missing data rate was higher than the valid response rates for transgender and other options using this method. Study 2 evaluated a method of asking two separate questions (i.e., one for current identity and another for birth-assigned category), with response options specific to each. Results showed no missing data and two times the transgender spectrum response rate compared to Study 1. Study 3 showed that the two-question method also worked in community samples, producing near-zero missing data. The two-question method also identified cisgender identities (same birth-assigned and current gender identity), making it a dynamic and desirable measurement tool for the social and medical sciences.
