Analytical expressions for the average adjustment interval and mean squared deviation for bounded adjustment schemes

This paper presents analytical expressions for the average adjustment interval and the mean squared deviation from target of the “bounded adjustment” schemes of Box and Luceno (1997a) under the assumption that the disturbances are generated from a double-exponential distribution. The solutions obtained are very close to those computed numerically for normally distributed innovations. This not only demonstrates the robustness of the schemes to the distributional assumptions, but also provides new useful expressions for the average adjustment interval and mean squared deviation from target. Expressions for the characteristic and probability mass functions of the adjustment interval are also given.     

Academic mothers,professional identity and COVID-19: Feminist reflections on career cycles,progression and practice

Based on a collection of auto-ethnographic narratives that reflect our experiences as academic mothers at an Australian university, this paper seeks to illustrate the impact of COVID-19 on our career cycles in order to explore alternative feminist models of progression and practice in Higher Education. Collectively, we span multiple disciplines, parenting profiles, and racial/ethnic backgrounds. Our narratives (initiated in 2019) explicate four focal points in our careers as a foundation for analyzing self-definitions of professional identity: pre- and post-maternity career break; and pre- and post-COVID-19 career. We have modeled this research on a collective feminist research practice that is generative and empowering in terms of self-reflective models of collaborative research. Considering this practice and these narratives, we argue for a de-centering of masculinized career cycle patterns and progression pathways both now and beyond COVID-19. This represents both a challenge to neo-liberal norms of academic productivity, as well as a call to radically enhance institutional gender equality policies and practice.     

Treatment progress of foster care adolescents with severe behavioural problems: Factors conditioning their performance in the residential treatment centres

Behavioural problems are a recurring issue in the child welfare system population. Normative residential centres do not have the characteristics to address the specific needs of these adolescents, so they are usually treated at therapeutic residential centres. In Catalonia (Spain), these cases are treated in intensive educational residential centres (CREIs), a variant of therapeutic residential care (TRC) facilities. This exploratory study seeks to understand the treatment progress of adolescents with severe behavioural problems who were placed in the CREIs, a variant of TRC facilities. Data from 206 cases, the totality of population under treatment in the CREIs, were collected using a questionnaire administered to the treating team. A cross‐sectional design was used, applying quantitative methods to analyse the incidence and interrelation of a series of variables related to the progress of adolescents in the CREIs. Significant differences among profiles by sex, place of origin, criminal offences, substance abuse and mental health disorders were found. Furthermore, adolescents who performed a positive treatment progress according to the professional staff arrived at the CREI at an earlier age and had longer stays than the group with an unremarkable progress. Logistic regression indicated that duration of stay in the centre and runaways predict the adolescents' treatment progress. This treatment is working well with the milder cases; however, it does not tend to be successful for adolescents with greater difficulties. It is recommended that interventions focus on factors that engage the adolescents in their own rehabilitation process, include substance abuse programmes and consider the gender perspective.     

Examining the Interaction of Daily Hassles Across Ecological Domains on Substance Use and Delinquency Among Low-Income Adolescents of Color

The increased risk for substance use and delinquency among adolescents of color has been partially attributed to increased exposure to daily hassles. Although a certain number of hassles are normative, especially among family and peers, adolescents of color experience more stressors in their neighborhood or directly related to fewer resources than their White counterparts. These hassles may interact across ecological systems to impact behavioral outcomes among adolescents. This may be especially true for young people living in public housing. Based on ecological systems theory, this study tests the relationship between experiences of hassles across multiple ecological levels and problem behaviors in a sample of 315 ethnically diverse early adolescents (M_age = 12; 51% female) living in public housing neighborhoods in two large metropolitan areas in the United States. A positive relationship was found between family hassles and both substance use and delinquency, as well as between school hassles and substance use. When the interactions between family, peer, school, and neighborhood/resource hassles were considered, five statistically significant interactions were found. The study results reinforce the role of contextual factors, such as living in low-income neighborhoods and the complexity of hassles interacting at multiple levels of a young person’s daily ecology, on adolescent outcomes.     

Preventing violence in disadvantaged communities: Strategies for building collective efficacy and improving community health

ABSTRACT

Violence is a critical health issue that compromises the strength of communities and permanently damages the lives of individuals and families. The impact of violence on health and well-being is particularly devastating in disadvantaged and minority communities, leading to negative health outcomes, including premature death. However, research suggests that communities can prevent violence and negative health outcomes by developing collective efficacy, which happens when neighbors share norms and values, trust one another, and are willing to intervene to address problems. Despite the importance of collective efficacy in preventing violence and improving health, almost no research has investigated actionable strategies to build collective efficacy in disadvantaged neighborhoods. This article describes a theoretical and conceptual model that illustrates how collective efficacy impacts community violence and related health outcomes. We begin by reviewing other approaches to community violence prevention, including criminal justice and developmental approaches. We then discuss how collective efficacy works and why it matters, including theoretical and empirical research explaining collective efficacy and its impact on community violence and health. We then discuss a research-based intervention that social workers can use to facilitate collective efficacy, including our conceptual model and the key components of the intervention. Finally, we discuss implications for social workers who are working with communities to address violence and related health issues.     

Comportamiento expresivo que antecede a la sonrisa social: Comparación entre lactantes normales y afectados por el síndrome de Down

Resumen

El objetivo de este trabajo ha sido comprobar la sonrisa social de los lactantes normales con la de los afectados por el síndrome de Down (mongolismo), atendiendo principalmente a los movimientos expresivos de las cejas que la precedieron. Por medio de una técnica de base anatómica, se analizaron las respuestas faciales de alegría de ocho niños normales y otros ocho con síndrome de Down, con edades comprendidas entre los tres y cinco meses, que aparecieron durante la interacción cara a cara con sus madres. Con independencia de su retraso cognitivo, los niños con síndrome de Down mostraron básicamente los mismos movimientos expresivos que los normales antes y durante la sonrisa. No obstante, se encontraron algunas diferencias en la frecuencia y duración media de las sonrisas, así como en la frecuencia de los movimientos expresivos de las cejas previos a la misma. Estos resultados se discuten en términos de las alteraciones psicofisiológicas que sufren los niños con síndrome de Down, derivadas de un estado de desequilibrio cromosómico.     

Positives and negatives of online dating according to women 50+

ABSTRACT

To understand the positives and negatives of online dating according to the lived experience of older women, telephone interviews were conducted with 45 women ages 50+ who date online. Interviews were audio recorded, transcribed verbatim, and thematically team coded. The opportunity to expand one’s social network for both friendships and romantic partners, the ability to control dating risks and pace of relationship formation, and knowing more about one’s partner were significant reported benefits of online dating. Dating online also includes unique risks, such as pervasive lying, attempted financial exploitation in the form of scammers, and unwanted electronic sexual aggression.     

The attitudes toward lesbians and gay men scale (ATLG): adaptation and testing the reliability and validity in Chile

Previous researchers have used the attitudes toward lesbians and gay men (ATLG) scale (Herek, 1988) and reported their own reliability coefficients and validity measures, but research on this subject is scarce in Chile. In order to determine if ATLG scale was a reliable and valid instrument in our country, we adapted and examined the psychometrics properties using a sample composed of 142 psychology and economics undergraduate students. This study found the ATLG scale to be reliable (a = .90) and valid for the Chilean population and is a recommended instrument for measuring attitudes toward gay men and lesbians.
