The role of frequently touched surfaces in the transmission of infectious diseases is well-documented, and the urgent need for effective surface technologies with antipathogen activity has been highlighted by the recent global pandemic and rise in antimicrobial resistance. Here, we have explored combinations of up to 3 different classes of compounds within a polymeric matrix to enable the fabrication of coatings with broad-spectrum activity. Compounds were either based on metals or metal oxides, namely, copper, silver, and copper oxide, essential oils, namely, cinnamaldehyde, tea tree oil, and carvacrol oil, or cationic polymers, namely, poly(ε-lysine) and poly(hexamethylene biguanide).

Aims: To determine the associations between COVID-19 school closures and school readiness skills for Chinese kindergarteners.

Design: We utilized the natural experimental condition created by local COVID-19 outbreaks in 2022 (Study 1) to compare school readiness skills of children whose kindergartens were closed for 5 months (Group 1) with children whose kindergartens stayed open (Group 2). We further compared the school readiness skills of one pre-COVID-19 cohort (Cohort 2019) with one COVID-19 cohort (Cohort 2021) from a fifth kindergarten (Study 2).

Objective: We examined the impact of the strict lockdown on 130 preschool-age children's daily routines and how their routine changes from pre-lockdown were related to child-parent relationship quality during the lockdown.

Background: To contain the spread of the COVID-19, the city of Wuhan underwent a strict 76-day lockdown, during which children's routines were drastically altered, yet families did not have a frame of reference to use to determine how changes in children's routines would be related to their family dynamics.

Method: Parents provided survey data on the amount of time their children spent daily on learning, screen devices, play and exercise, and nighttime sleep before, during, and after the lockdown.

Objective: Research suggests that screen exposure presents a risk for ADHD behaviors in young children. However, the operationalization of screen exposure remains murky and longitudinal data is scarce. In this paper, we examined the relations between better operationalized daily screen time and behaviors of inattention and behaviors of hyperactivity/impulsivity in three cohorts of community samples of young Chinese children.

Research on the role of early relationships with parents on youth's anxiety and depression, especially in collectivist societies such as China, is limited. To fill this gap, we investigated the unique role of early relationship with mothers and fathers, respectively, in Chinese youth's anxiety and depression outcomes. The participants were 347 Chinese college students from 20 provinces.

Background: Controversy persists in the treatment of high-grade spondylolisthesis (HGS). Surgery is recommended in patients with intrusive symptoms and evidence debates the competing strategies. This study compares the radiologic outcomes and postoperative complications at a minimum of 2 years follow-up for patients with HGS treated with instrumented fusion with partial reduction (IFIS) with those treated with reduction, decompression, and instrumented fusion (RIF).

Global trends increasingly appear to be legitimizing same-gender relationships, yet international research shows that despite statutory rights to marry-and by extension, adopt children-same-gender couples continue to experience difficulties when trying to adopt. Primary among these barriers are the persistent heteronormative beliefs, which strongly underpin the unfounded myths about parenting abilities of same-gender couples. Such biased beliefs are perpetuated by some adoption professionals who oppose placing children with lesbian or gay couples.

Existing research suggests that parental absence per se does not have a main effect on children's cognitive development. However, this body of research is confounded by decreased family finance resulted from parental absence. Further insights on children's cognitive development can be gained by studying situations where parental absence actually leads to higher family finance.

We adopted a person-centered approach to identify maternal feeding profiles among urban Chinese mothers of preschoolers, including two previously unexamined culturally-emphasized practices, and examine the associations between these feeding profiles and child and parent characteristics. Participants included 167 mothers and their preschoolers residing in Shanghai, China. Mothers reported on their feeding beliefs and practices, perceptions of child's body shapes, child dietary intake, and family demographic information.

In this study, we have proposed a novel solvent-based method using a specific concentration of 3M™ Novec™ HFE-72DE and 7200 solvents to untangle duct tape from porous article with minimal impact to the quality of latent fingerprint deposited on the sticky-side surface of duct tape. A series of experiments determined that a mixture of 30% HFE-72DE:7200 (v/v) was found to be the most effective to separate various brands of duct tape from different types of porous surface, including office copy paper, newspaper, cardboard, and tissue wipe, which had been stored for up to 30 days before untangling. Further studies also revealed that 30% HFE-72DE:7200 was compatible with three common fingerprint development methods for porous articles, namely ninhydrin, indanedione-zinc, and physical developer.

Given the current political climate in the United States, it is ever more important to understand the role political ideology plays in the counseling profession. Our study examined the role of political ideologies in 467 licensed mental health counselors' preferred counseling theories in clinical practice. We found (a) most participants reported liberal political ideologies; (b) the participants preferred cognitive-behavior therapy (CBT), humanistic/constructivist/existentialist, and mindfulness-based theories over systemic, psychodynamic, and experiential theories; and (c) self-identification as conservative, registration with the Republican Party, and endorsement of Libertarian beliefs predicted a preference for CBT, self-identified liberal ideology predicted a preference for psychodynamic theory, and lower levels of libertarian beliefs predicted a preference for humanistic theories.

Wording effects associated with positively and negatively worded items have been found in many scales. Such effects may threaten construct validity and introduce systematic bias in the interpretation of results. A variety of models have been applied to address wording effects, such as the correlated uniqueness model and the correlated traits and correlated methods model.

The Children's Sleep Habits Questionnaire (CSHQ) is widely used in clinical settings to screen for sleep problems in children aged 4-10 years. Existing studies on children in different cultures have included children across a wide age range and results have raised questions about CSHQ's psychometric quality. Our study addressed some of the limitations of existing studies by focusing on Chinese children within a much narrower age range of 4-5 years old.
