Cross-notation knowledge of rational numbers predicts fraction arithmetic.

Background: Recent research showed that cross-notation magnitude knowledge of fractions and decimals was related to better performance in fraction arithmetic, but it remains unclear whether it made an independent contribution to fraction arithmetic longitudinally when other cognitive variables are considered.

Aims: To examine the extent to which children's earlier knowledge of cross-notation magnitude predicted subsequent performance in fraction addition and subtraction as well as fraction multiplication and division longitudinally.

Sample: Three hundred and fifty-four Chinese children (M = 112.

Weight stigma from romantic partners: Its relations with maladaptive and adaptive coping and depressive symptoms.

Social devaluation of being overweight is common in daily life, but little is known about the weight stigma in romantic relationships. The present study investigated the roles of maladaptive and adaptive coping strategies in the relation between the experience of weight stigma in romantic relationships and depressive symptoms in men and women, respectively. Analyses of gender differences and structural equation modeling yielded several findings.

Longitudinal Links Between Parental Failure Mindsets, Helicopter Parenting, and Fixed Mindset of Intelligence in Adolescents.

Evidence for the prospective associations among parental failure mindset, helicopter parenting, and children's intelligence mindset is lacking. This three-wave longitudinal study (12 months apart between waves) addressed this research gap by testing whether perceived maternal helicopter parenting mediated the link between perceived maternal failure mindset and intelligence mindset. Participants included 525 Chinese adolescents (47.

You are how you speak: The roles of vocal pitch and semantic cues in shaping social perceptions.

Social perceptions of speakers are influenced by their voice information, including vocal characteristics and semantic content. Our study investigated how individuals' warmth- and competence-related perceptions of speakers were affected by vocal pitch levels (i.e.

Effects of Biological Determinism on Beliefs and Attitudes About Transgender People: Psychological Essentialism and Biased Assimilation.

This experimental study examined the effects of biological attributions on individuals' beliefs and attitudes toward transgender people and the moderating role of right-wing authoritarianism (RWA). We randomly assigned 183 Chinese university students (men: n = 85, women: n = 98) to read one of three fictitious articles. The first article suggested that transgender identity was causally linked to biology (biological determinist condition), the second one highlighted the interplay between biological and environmental factors (epigenetic condition), whereas the third article did not mention the origins of transgender identity (control condition).

The association between three key social determinants of health and life dissatisfaction: A 2017 behavioral risk factor surveillance system analysis.

Poor health outcomes disproportionately impact certain populations in the United States owing to the inequitable distribution of social determinants of health (SDOH). Using the 2017 Behavioral Risk Factor Surveillance System (BRFSS), we estimated the association of three adverse SDOH (housing insecurity, food insecurity, and financial instability) with life dissatisfaction. Participants were from Wisconsin, Minnesota, and Ohio, the only states that included the SDOH and Emotional Support and Life Satisfaction modules (n = 25,850).

Body weight contingent self-worth predicts depression in adolescent girls: The roles of self-esteem instability and interpersonal sexual objectification.

This 3-year longitudinal study examined the extent to which body weight contingent self-worth (CSW) predicted depressive symptoms in 439 adolescent girls and the roles of unstable self-esteem and interpersonal sexual objectification in this association. Half-longitudinal mediation showed that the indirect effect of body weight CSW on depression via instability of self-esteem was significant. Prior levels of body weight CSW predicted increases in unstable self-esteem, which predicted increments in depressive symptoms over time.

Transnasal endoscopic medial maxillary sinus wall transposition with preservation of structures.

Objectives/hypothesis: To evaluate the increase in access to the maxillary sinus (MS) with transnasal endoscopic medial maxillary sinus wall transposition (TEMMT), while preserving major structures of the nasal cavity.

Study Design: The study was divided into three parts: anatomical, radiographic, and case series.

Methods: Three cadaveric dissections (total of six sides) confirmed the feasibility of the TEMMT approach.
