Recent national reports suggest that nearly 1,000,000 families with children experience homelessness and that this number is rising (National Center on Family Homelessness, 2009; U.S. Conference of Mayors, 2010; U.S. Department of Housing and Urban Development, 2011). Families experiencing homelessness are disproportionately more likely to have experienced economic, health, and social risk factors. These experiences can adversely influence the parent–child relationship. The purpose of this article is to (a) review the literature on the determinants and contextual issues of parenting in shelters; (b) describe specific programs that are focused on positive parenting in the context of homelessness; and (c) provide practice, research, and policy recommendations for supporting positive parenting among families living without homes.

Implications of the findings are discussed in terms of potential influences on the development of functional disability in youth.

Increased interest in alternatives to lithium-ion batteries has led to promising work on sodium-ion batteries, particularly with layered oxide cathode materials. For practical applications, however, their lower energy density and cycle life relative to lithium-ion layered oxide cathodes make them an inadequate alternative. A greater utilization of sodium ions with charging voltages >4 V versus Na would increase the energy density, but higher cutoff voltages cause decreased cycling stability. To date, very little is known on the capacity fade mechanisms of layered oxide cathodes operating in the high-voltage regime. We herein report, for the first time, the effects of extended high-voltage cycling in O3-type Na(Ni 0.3 Fe 0.4 Mn 0.3 )O 2 . By analyzing the extended cycling performance in conjunction with X-ray diffraction, galvanostatic intermittent titration technique, electrochemical impedance spectroscopy, and X-ray photoelectron spectroscopy, the interconnected mechanisms of capacity fade are elucidated. An irreversible loss of the high-voltage (OP2) phase transition above 4 V due to iron migration causes rapid capacity fade during the initial stage of cell operation. After the disappearance of the OP2 phase, electrolyte decomposition and structural degradation continue to occur, leading to a significant impedance growth and faster capacity fade than cells cycled at 4 V. This study provides valuable insight into the fundamental limitation of O3 layered oxide cathodes and offers guidelines for future materials modification.

For proficiency in an evidence-based treatment (EBT), mental health professionals (MHPs) need training activities extending beyond a one-time workshop. Using data from 178 MHPs participating in a statewide TF-CBT dissemination project, we used five variables assessed at the workshop, via multiple and logistic regression, to predict participation in three post-workshop training components. Perceived in-workshop learning and client-treatment mismatch were predictive of consultation call participation and case presentation respectively. Attitudes toward EBTs were predictive of trauma assessment utilization, although only with non-call participants removed from analysis. Productivity requirements and confidence in TF-CBT skills were not associated with participation in post-workshop activities.

The current study examined the potential mechanism of emotional-social intelligence in the relation between exposure to community violence (CV) and psychological adjustment in ethnic minority youth. Using responses from 114 low-income youth ages 11 to 15 years old, results indicated that component parts of emotionality (i.e., awareness of one's feelings, recognition of others' feelings, managing negative emotions, and flexible problem-solving) were stronger predictors for youth adjustment (i.e., internalizing & externalizing symptoms & adaptive behaviors) than exposure to CV alone. Additionally, youths' abilities to manage negative emotions significantly mediated all three indicators of adjustment. The mediational role of stress management in the relation between exposure to CV and psychological adjustment and areas for future research are discussed.
