Analysis of supersaturated designs via the Dantzig selector

A supersaturated design is a design whose run size is not enough for estimating all the main effects. It is commonly used in screening experiments, where the goals are to identify sparse and dominant active factors with low cost. In this paper, we study a variable selection method via the Dantzig selector, proposed by Candes and Tao [2007. The Dantzig selector: statistical estimation when p$p$ is much larger than n$n$. Annals of Statistics 35, 2313–2351], to screen important effects. A graphical procedure and an automated procedure are suggested to accompany with the method. Simulation shows that this method performs well compared to existing methods in the literature and is more efficient at estimating the model size.     

“But I’m not a racist!” Phenomenology,racism, and the body schema in white,pre-service teacher education

In this article, I call for a phenomenological turn in educating white, pre-service teachers. As opposed to dominant pedagogical models which focus on changing one’s beliefs about race, phenomenology points toward the importance of pre-conceptual, pre-critical forms of racial embodiment. Here I draw upon recent work on the different between body image (beliefs about the body) and body schema (what the body can do). The worry is that existing forms of anti-oppressive education miss the centrality of the schema, and thus do not go far enough in uncovering the embodied, perceptual roots of racism.     

AFFECTIVE RESPONSES WITHIN A COMPLEX DECISION-MAKING TASK: THE INFLUENCE OF “PERCEPTUALLY” ILL-STRUCTURED PROBLEMS

The perceptual effects of varying levels of expert advice for potentially improving on strategic decisions were examined in conjunction with goals. The amounts of advice about decision alternatives, as well as assigned goals ranging from “nearly impossible” to “easy,” were manipulated. The task used was complex and functioned perceptually as an “ill-structured” problem. Mixed results indicated that more advice significantly affected satisfaction but advice in general had little influence on effort. On the other hand, as goal difficulty decreased, satisfaction and effort significantly increased. Easy goals were superior to more difficult ones within this perceptually ill-structured decision-making situation.     

Walking Ability is Associated with Social Communication Skills in Infants at High Risk for Autism Spectrum Disorder

Achievement of early motor milestones in infancy affords new opportunities for social interaction and communication. Research has shown that both motor and social deficits are observed in infants who later develop autism spectrum disorder (ASD). This study examined associations between motor and Social communication skills in 12‐month‐old infant siblings of children with ASD who are at heightened risk for developmental delays (N = 86) and low‐risk, typically developing infants (N = 113). Infants were classified into one of three groups based on their walking ability: walkers (walks independently), standers (stands independently), or prewalkers (does not yet stand or walk independently). Social communication and cognitive skills were assessed with two standardized assessments (Communication and Symbolic Behaviors Scales [CSBS] and Mullen Scales of Early Learning) and compared across the three walking groups. Results demonstrated that high‐risk walkers showed superior Social communication skills, but commensurate cognitive skills, compared to high‐risk prewalkers. In contrast, Social communication and cognitive skills were largely comparable for low‐risk infants, regardless of walking status. Findings suggest that for high‐risk infants, who are already vulnerable to developmental delays and ASD, independent walking may facilitate the emergence of Social communication abilities. Pivotal motor milestones may serve as useful indicators of Social communication delays and targets for intervention.     

Colorful Disclosures: Identifying Identity-Based Differences and Enhancing Critical Consciousness in Supervision

ABSTRACT

Managing microaggressions and marginalizing experiences while negotiating the ongoing oppression that occurs in micro, mezzo, and macro settings can be particularly challenging for clinicians of color. Thus, supervision with clinicians of color must include affirmation, empowerment, and exploration of the intracultural/intercultural dynamics inherent in the treatment-providing process and clinical supervision. Through case studies, autoethnographic studies of our supervision experiences, and interviews with supervisors and supervisees, we reflect on how axes of identity, including race, power, and privilege, inform practitioners’ clinical lenses and affect their vulnerability in treatment and the clinical supervision dyad. Special attention is placed on the clinical supervisor–clinician–client triad (the triple process) and the interpersonal dynamics of cultural sensitivity, cultural humility, and authentic responsiveness that supervisors aim to model and cultivate in the supervisory relationship. In addition to sustaining clinical growth for clinicians of color, adding this level of complexity to supervision supports equity in direct clinical practice, enhancing efficacy outcomes for clients and communities. Recommendations and pedagogical strategies are offered to support supervisors in initiating difficult dialogues and shifting the paradigm to promote this transformational perspective.     

Seeking Clarity and Confidence in the Divorce Decision-Making Process

There is a well-established literature dedicated to why couples divorce, transitions associated with divorce, and the impact of divorce on families. However, little is known about the divorce decision-making process. We conducted in-depth interviews with individuals who have recently considered divorce (n = 30) and asked specifically about the roles of 2 concepts in their decision-making process: clarity and confidence. Three major themes emerged from the data: (a) Clarity about a decision to divorce or stay married is desired, it fluctuates, and takes time to find; (b) pivotal moments can bring clarity; and (c) confidence (in the final decision) is desired. Clinical implications and directions for future research are discussed.     

Cambodian Refugee Families: Impacts of Immigration-Related Stressors on Intergenerational Relationships

The purpose of this study was to elucidate Cambodian refugees’ perceptions of immigration-related stressors and their impacts on intergenerational relations during the processes of immigration and settlement. We used narrative analysis to evoke older immigrants’ voices as they transitioned to the United States. Thirty-one Cambodian immigrants were interviewed using open-ended interview guides informed by ethnographic tenets of data collection. Participants expressed (a) changes in family structure and elder isolation and (b) intergenerational ambivalence and elder’s dependence on adult children as products of immigration-related stressors. Implications of these results for refugee and immigrant mental health research are discussed.     

“We will never be normal”: The Experience of Discovering a Partner Has Autism Spectrum Disorder

Online forums and lay literature suggest that partners of individuals with Autism Spectrum Disorder (ASD) experience depression, distress, and trauma in their everyday lives, exacerbated during the time surrounding diagnosis. In this content analysis, 29 participants were provided with an online open‐ended statement asking them to describe in writing their experiences of discovering that their partners had ASD during their relationships. Six themes emerged, including: facing unique challenges within relationships; insisting partners seek diagnosis; initial shock and relief; losing hope for normalcy; making accommodations within relationships; and wishing for professional support. Marriage and family therapists should help couples minimize blaming and promote self‐awareness, appropriate relationship expectations, and mutual understanding. Future research should explore the overall experience of neuro‐mixed relationships for both partners.     

Immigrant Latino Families Saving Against Great Odds: The Case of CSAs and the Prosperity Kids Program

Children’s savings account programs are interventions that seek to engage disadvantaged children and their families in early college saving, cultivate college-saver identities, and reduce disparities in educational and economic outcomes. Existing research has revealed positive effects of CSAs on children’s outcomes, but questions remain about how and for whom CSAs facilitate these outcomes. This study uses account data from 493 accountholders and findings from interviews with 50 participants to examine asset accumulation and savings experiences among mostly low income, Latino families in New Mexico’s Prosperity Kids CSA program. One-third of the families made a deposit into their child’s account designated as “savers” with a median total contribution of $123 and a median account balance, including initial seed deposit, of $345. Longer duration of program enrollment and fewer number of unexcused absences predicted savers status. Qualitative findings highlight emerging college-saver identities, viewed through the framework of identity-based motivation, understood to include salience, normalization of difficulty, and group congruence. Qualitative interview data further suggest that initial seed money, deposit incentives, and withdrawal restrictions were important influences on participants’ saving. These findings suggest CSA features that may encourage positive savings outcomes for economically disadvantaged households and, then, that may have implications for future CSA policy development.
