Character strengths

The organization of water molecules and ions between charged mineral surfaces determines the stability of colloidal suspensions and the strength of phase-separated particulate gels. In this article, we assemble a density functional that measures the free energy due to the interaction of water molecules and ions in electric double layers. The model accounts for the finite size of the particles using fundamental measure theory, hydrogen-bonding between water molecules using Wertheim's statistical association theory, long-range dispersion interactions using Barker and Henderson's high-temperature expansion, electrostatic correlations using a functionalized mean-spherical approximation, and Coulomb forces through the Poisson equation...

OBJECTIVE: Does whole trait theory work for character strengths? This study examines the daily within- and between-person variability of the manifestations of positively valued lower-order personality characteristics, namely character strengths, their convergence with trait character strengths, and their relationships to daily measures of affect. BACKGROUND: Manifestations of personality traits vary both between- and within people. So far, research has focused on between-person differences in character strengths, while within-person differences have been neglected...

BACKGROUND: Conventional petroleum-based packaging films cause severe environmental problems. In this work bio-edible film as a safe to replace petroleum-based polymers was introduced. A food application for edible sachets and a composite edible film (EF) from marine algae, Gracilaria fisheri (GF) extract were proposed. RESULTS: Carbohydrates were the most prevalent component in fresh GF fronds. Under neutral conditions at 90 °C for 40 min, the extract's structure was determined by FTIR to be a carrageenan-like polysaccharide...

Bees are excellent pollinators and serve an essential environmental purpose. However, little is known about the wellbeing impact of bees on humans. This research addressed the knowledge gap concerning the impact of beekeeping on the wellbeing of beekeepers and their families, focusing on the often-overlooked psychological, emotional, and social dimensions. Thirty farmers in Ireland participating in the Let it Bee project, aimed at promoting biodiversity and water source protection, were provided with bee hives...

Multi-component Positive Psychology Interventions (mPPIs) in secondary schools have been shown to improve mental health outcomes for young people. The Hummingbird Project mPPI is a six-week program of workshops designed to introduce a variety of positive psychology (PP) concepts to secondary school-aged children in schools to improve well-being, resilience, and hope. The effects on mental distress, however, were not explored. The current study, therefore, was designed to replicate the effects of the Hummingbird Project mPPI on positive mental health and to also explore the effects on symptoms of mental distress...

BACKGROUND: Many senior adults are at risk of mental and physical disorders due to a lack of sufficient exercise. Therefore, adherent exercise should be urgently promoted to improve senior adults' muscle strength, preventing falls and conditions caused by physical and cognitive decline. However, off-the-shelf exercise games, so-called exergames, are mainly targeted at the younger generation or children, while senior adults are neglected, when this age group strongly needs exercise. Exergames could serve as a health intervention for promoting exercise...

We review recent advances in the theoretical, numerical, and experimental studies of critical Casimir forces in soft matter, with particular emphasis on their relevance for the structures of colloidal suspensions and on their dynamics. Distinct from other interactions which act in soft matter, such as electrostatic and van der Waals forces, critical Casimir forces are effective interactions characterised by the possibility to control reversibly their strength via minute temperature changes, while their attractive or repulsive character is conveniently determined via surface treatments or by structuring the involved surfaces...

Plant-mediated solution casting is used to develop eco-friendly polymer blend nanocomposites from polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) doped with Silver (Ag), Ferrous (Fe) monometallic and Silver-Ferrous (Ag-Fe) bimetallic nanoparticles (NPs). These nanocomposites were studied to understand their electromagnetic interface (EMI) shielding efficiency and antimicrobial activities, besides evaluating their physical and chemical properties. The Fourier transform infrared (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and energy dispersive X-ray (EDX) characterization techniques were used to examine the interactions between the polymers, the presence of silver and ferrous particles in the composites, the crystallinity shift, the surface morphology, the shape and size of the nanoparticles and the distribution of the nanoparticles in the composites...

We use a combination of many-body perturbation theory and time-dependent density functional theory to study the optical and electronic properties of hydrogen terminated silicon nanoparticles. We predict that the lowest excited states of these silicon nanoparticles are excitonic in character and that the corresponding excitons are completely delocalised over the volume of the particle. The size of the excitons is predicted to increase proportionally with the particle size. Conversely, we predict that the fundamental gap, the optical gap, and the exciton binding energy increase with decreasing particle size...

The photochemical dynamics of the acetic acid and trifluoro-acetic acid dimers in hexane are studied using time-resolved infrared absorption spectroscopy and ab initio electronic structure calculations. The different hydrogen bond strengths of the two systems lead to changes in the character of the accessed excited states and in the timescales of the initial structural rearrangement that define the early time dynamics following UV excitation. The much stronger hydrogen bonding in the acetic acid dimer stabilizes the system against dissociation...

School dropout may have important negative consequences for the individual as well as for society. Because school grades in lower secondary education are essential for the completion of upper secondary school, remotivating demotivated ninth graders with an increased risk of dropping out seems vital. This study focuses on the experiences of Norwegian ninth grade boys at a learning camp aimed at preventing school dropout through increasing school engagement, learning, and well-being before tenth grade. We interviewed 17 of the 29 participants in one particular camp to study their experiences and analyze how they were related to the theoretical underpinning of the camp...

Chronic wounds differ from acute wounds by remaining in the inflammatory phase for a long time. This chronic inflammation confers a high concentration of inflammatory cytokines, proteases, and ROS. Likewise, the pH environment of chronic wounds has been recorded within the range of 7.2-8.9 due to the alkaline by-products of bacterial proliferation. In this work, differences in pH between healthy skin and chronic cutaneous wounds have been used for the design and development of pH-responsive gelatin-based nanoparticles (NPs)...

Members of Botryosphaeria s.l. have an extensive history as cankering pathogens of stressed and declining oak trees in the eastern United States (Ferreira et al. 2021). The host range, distribution, and virulence among two closely related species, Diplodia corticola and D. gallae, remains unclear (Brazee et al. 2023). On 15 August 2023, a survey was conducted at a declining natural hardwood site in Shenandoah County, Virginia (GPS coordinates 38.922089, -78.606125). One mature Quercus coccinea tree that displayed scorched leaf margins and branch dieback was felled and a cankered branch from the crown was sampled (Fig...

OBJECTIVE: This mixed methods study examined depictions of spirituality among people with psychosis in influential television programming. Spirituality is a central strength for many people with psychosis. Yet, despite the important role media plays in shaping perceptions, little research has examined the intersection between spirituality and psychosis in popular media. METHODS: To address this gap, we conducted a content analysis of the 50 most viewed primetime fictional television shows over a 10-year period as determined by the Nielsen rating organization...

Selective laser melting (SLM) technologies are becoming increasingly popular. The aim of the work is to compare the metallographic structure, hardness, and selected strength properties of alloys obtained by casting and by SLM, with a particular emphasis on fatigue strength. Twenty Cr/Co alloy bars were made by casting or SLM, and samples of appropriate dimensions were prepared for individual tests. The microstructures of the samples were tested by metallography, and then tested for hardness, impact strength, tensile strength, bending strength, and fatigue strength; they were also subjected to fracture after bending, tensile, fatigue, and impact tests, with the resulting fractures examined by scanning electron microscopy (SEM)...

BACKGROUND: The present study examined the associations among ethnic identity, perceived discrimination and multiple indicators of positive youth development (PYD; i.e., intrapersonal-oriented competence, interpersonal-oriented competence, confidence, caring, character, family connection, peer connection, school and community connection, positive attitudes towards diversity and cultural pride) that were specifically identified among second-generation Chinese-American youth. METHODS: Participants were 196 second-generation Chinese-American youth (N girl  = 93; M age  = 14...

INTRODUCTION: Appreciative inquiry harnesses an individual's strengths to realize positive change, and a flourishing-focused mindset emphasizes engagement, social connectivity, and seeking meaningful work. Though the impact of these models on physician well-being and career planning has been evaluated in graduate medical education, their integration into career development initiatives for faculty has been limited. We designed a workshop to nurture hospitalist career development, based on our CORE2 conceptual framework (character strengths, overall vision, role assessment, explicit goals, and evaluation)...
