Child neglect, recognized as the most prevalent form of child maltreatment with profound repercussions on children's development, has received limited scholarly attention compared to abuse. The current study addresses this shortfall with a qualitative research investigation involving 10 multicultural focus groups of youths aged 12 to 15. The research examined how young individuals identify signs of child neglect and discern whether formal and informal sources of assistance may be relied upon to assist in addressing this issue.

Post-natal home visits have been shown to be one of the most effective ways to prevent child maltreatment and reduce risks among children. Unfortunately, these programs tend to be expensive and thus not accessible or practical in many contexts. To address this problem, this paper reviews the literature on home visits conducted shortly after giving birth, considering different types of programs and their outcomes, while focusing on short-term and volunteer-based programs, two approaches that can answer the gap in accessibility.

Child neglect is considered the most common form of child maltreatment with severe implications for children's development. Nonetheless, there is a dearth of scholarly literature examining child neglect, possibly stemming from a lack of consistent definition. The current qualitative study addresses this gap by aiming to understand the phenomena of child neglect from the direct perspective of youth from the general population, a perspective that has so far barely been considered.

Metal halide perovskites are an attractive class of semiconductors, but it has proven difficult to control their electronic doping by conventional strategies due to screening and compensation by mobile ions or ionic defects. Noble-metal interstitials represent an under-studied class of extrinsic defects that plausibly influence many perovskite-based devices. In this work, doping of metal halide perovskites is studied by electrochemically formed Au interstitial ions, combining experimental data on devices with a computational analysis of Au interstitial defects based on density functional theory (DFT).

While the strategy of Shared Decision Making (SDM) originated in the medical field and was later adopted into the mental health arena, little attention has been paid to practice in the broader fields of the allied health and social care professions. These professions are grounded in the recognition of a need for practice that reflects the partnership and collaboration of the professional and the service user working together to further the health and well-being of the user. A pilot training module was developed to introduce and support students in their journey from exposure to the co-production ideology and the SDM strategy into clinical practice in the allied health and social care professions.

: University and college students are not usually identified as a population at risk during the COVID-19 pandemic. Yet, there is growing evidence of their specific distress associated with facing multiple abrupt changes and the need for rapid adaptation to a variety of academic, social, and financial challenges. The extent of their exposure to COVID-19 media and the associated media-related stress may further impair students' perceived coping.

Article Synopsis
  • Understanding the energy level alignment at metal halide perovskite (MHP) interfaces is crucial for optimizing their use in optoelectronic devices, but the inherent electronic properties of MHPs remain controversial.* -
  • Recent photoemission experiments show that methylammonium lead triiodide (MAPbI) acts as an intrinsic semiconductor without oxygen, but the introduction of oxygen leads to significant p-doping, affecting the position of the Fermi level.* -
  • Oxygen can reversibly diffuse into the MAPbI material over extended timescales, and it appears to substitute for iodine vacancies, which emphasizes the need for careful handling of oxygen during experimentation to ensure accurate electronic property analyses.*

The time it takes to begin treatment in life-threatening situations is critical. Ambulance transport to the hospital in such situations ensures quick and effective treatment but is not always readily available in nonurban areas, or not preferred by the public, for various reasons. The purpose of this qualitative study was to examine the factors that deter or encourage ambulance use in life-threatening situations in the geographic periphery from clients' perspectives.

The significant role of the community in the lives of children and youth at-risk has become increasingly clear to social work academics and professionals over the last three decades. Alongside the more traditional individual and family responses, community interventions have been designed to catalyze change in the environment of children and youth at-risk and supply holistic and sustainable responses to their needs. Ten such community intervention programs were identified from the United States, Australia, Canada, and Israel.

We consider the Br vacancy in CsPbBr as a prototype for the impact of structural dynamics on defect energetics in halide perovskites (HaPs). Using first-principles molecular dynamics based on density functional theory, we find that the static picture of defect energetics breaks down; the energy level associated with a Br vacancy is found to be intrinsically dynamic, oscillating by as much as 1 eV on the picosecond time scale at room temperature. These significant energy fluctuations are correlated with the distance between the neighboring Pb atoms across the vacancy and with the electrostatic potential at these Pb atomic sites.

In Study 1 of this two-part investigation, we present a "central tendency approach" and procedures for assessing overall interrater agreement across multiple groups. We define parameters for mean group agreement and construct bootstrapped confidence intervals around the mean population parameters for r, AD, and ICC(1). In Study 2, we extend assessments of overall interrater agreement by developing a "matched difference approach" and procedures for assessing real versus pseudo agreement in a sample of groups.

To assess short-term placebo response in 6- to 13-year-old children with ADHD, children who were administered a double-blind placebo-methylphenidate trial, 1 week each, were included in the analysis. Conners' parents and Teacher Rating scales, the Aggregate Neurobehavioral Student Health and Educational Review inventory, and the Matching Familiar Figure Test were employed. A reduction of 30% or more in one or more of the teachers report subscales was observed in 18.

Objective: To compare the effectiveness of two methods in encouraging the consideration of a leap from one patient management routine to another: (i) real-time review of the facts by an external medical team (ii) implementation of the 're-thinking-protocol' ('de-Freezing') by both treating and external medical teams.

Design: Students accompanied doctors, nurses and patients as non-interrupting observers. When an obvious gap between the expected and actual findings occurred, it was discussed four times: by two teams (treating team, external medical team) in two discussion modes (real-time review, de-Freezing-questionnaire).

The optical and electronic properties of suspensions of inorganic fullerene-like nanoparticles of MoS2 are studied through light absorption and zeta-potential measurements and compared to those of the corresponding microscopic platelets. The total extinction measurements show that, in addition to excitonic peaks and the indirect band gap transition, a new peak is observed at 700-800 nm. This spectral peak has not been reported previously for MoS2.

Despite the widespread use of interrater agreement statistics for multilevel modeling and other types of research, the existing guidelines for inferring the statistical significance of interrater agreement are quite limited. They are largely relevant only under conditions that numerous researchers have argued rarely exist. Here we address this problem by generating guidelines for inferring statistical significance under a number of conditions via a computer simulation.
