Recharging exhausted parents: How and when involvement in children's education increases working parents' flourishing at home and engagement at work.

Parental involvement in children's education is highly valued and encouraged in many societies. While existing research has mainly focused on the positive effects parental involvement has for children, we argue that engaging in such quality parent-child interactions can also be a resource-gaining process for parents. Drawing on the conservation of resources theory and the work-home resources model, the current study aims to investigate how and when working parents' involvement in children's education enhances their well-being at home and engagement at work.

Amine vapor-responsive ratiometric sensing tag based on HPTS/TPB-PVA fluorescent film for visual determination of fish freshness.

In this study, amine vapor-sensitive films with ratiometric fluorescence attributes were developed. The pH-sensitive fluorescein 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) and its tetraphenylethylene derivative (TPB) were selected as ratiometric indicators and incorporated into a polyvinyl alcohol (PVA) matrix to produce HPTS/TPB-PVA films. The films responded well to amine vapors, and the interference of aromatic vapors did not substantially affect the fluorescence signals of the films.

The effect of harvesting the anterior half of the peroneus longus tendon on foot morphology and gait.

Background And Objectives: In anterior cruciate ligament reconstruction, the strength of the graft was found to be unsatisfactory usually the anterior half of the peroneus longus tendon was taken for supplementation, but the effect on foot and ankle function and gait in the donor area is unclear. This study aims to explore the changes in the ankle and gait after using the harvested anterior half of the peroneus longus tendon as a reconstruction graft for the anterior cruciate ligament.

Methods: A total of 20 patients, 6 males and 14 females, aged 18 to 44 years, with unilateral anterior cruciate ligament injuries, underwent reconstruction using the harvested anterior half of the peroneus longus tendon as a graft between June 2021 and December 2021.

Association of hardware removal with secondary osteonecrosis following femoral neck fractures: a systematic review and meta-analysis.

Background: It has been controversial that whether hardware removal will increase the risk of osteonecrosis of femoral head (ONFH) in fracture-healed patients who underwent internal fixation for femoral neck fractures (FNFs). This meta-analysis aimed to clarify the association of hardware removal with secondary hardware removal-induced ONFH (HR-ONFH).

Methods: Four electronic databases (PubMed, Embase, Web of Science, Cochrane Library) were searched for eligible studies published up to March 10, 2023.

Methods: From September 2020 to September 2022, a total of 258 consecutive patients (60 male, 198 female;mean age 81.3 years) with intertrochanteric fractures were included in this study.

Nonanatomical reduction of femoral neck fractures in young patients treated with femoral neck system: a retrospective cohort study.

Purpose: Negative buttress reduction should be avoided in the treatment of femoral neck fractures (FNFs) using conventional fixation. As the femoral neck system (FNS) has been recently developed and utilized widely to treat FNFs, the association of reduction quality with postoperative complications and clinical function has not been clarified. The purpose of this study was to evaluate the clinical effect of nonanatomical reduction in young patients with FNFs treated with FNS.

Differential Antecedents and Consequences of Affective and Cognitive Ruminations.

Adopting the information processing perspective, the current study aims to investigate the differential effects of affective and cognitive ruminations on individuals' affective states and learning behavior, and to further explore their differential mediating roles in transmitting effects of challenge and hindrance stressors on affect and behavior. A two-wave survey, in which stressors and ruminations were measured in the first wave and affective states and learning behavior were measured in the second, was conducted to obtain responses from 410 employees. As expected, affective and cognitive ruminations were differently associated with challenge stressors (i.

The Chain Mediating Effect of Negative Perfectionism on Procrastination: An Ego Depletion Perspective.

Extant research has consistently demonstrated that negative perfectionism is an important driver of procrastination. However, existing studies suffer from several salient limitations, such as an inadequacy in understanding its mediating mechanism, and the lack of an overarching theoretical framework. Accordingly, the present study adopts the ego depletion theory to investigate how and under what conditions negative perfectionism leads to procrastination.

Methods: From October 2019 to October 2020, 12 patients with tibial avulsion fracture of posterior cruciate ligament were treated with the arthroscopic knot-free anchor and Endobuton titanium plate, including 9 males and 3 females. The age ranged from 23 to 58 years old.

Creativity as a Means to Well-Being in Times of COVID-19 Pandemic: Results of a Cross-Cultural Study.

The coronavirus disease 2019 (COVID-19) pandemic has brought about unprecedented uncertainty and challenges to the worldwide economy and people's everyday life. Anecdotal and scientific evidence has documented the existence of a positive relationship between the experience of crisis and creativity. Though this appears to be ubiquitous, the crisis-creativity-well-being relationship has not been sufficiently examined across countries and using a working adult sample.

Kick the Cat: A Serial Crossover Effect of Supervisors' Ego Depletion on Subordinates' Deviant Behavior.

Drawing on the crossover model and conservation of resources theory, we explore the mechanism through which supervisors' ego depletion induces subordinates' deviant behavior. Using the two-wave survey data from 24 supervisors and their 192 respective subordinates, we found supports for our hypotheses that (a) abusive supervision mediated the effect of supervisors' ego depletion on subordinates' ego depletion; (b) subordinates' ego depletion mediated the effect of abusive supervision on subordinates' deviant behavior; and (c) abusive supervision and subordinates' ego depletion serially mediated the effect of supervisors' ego depletion on subordinates' deviant behavior. Our serial crossover model posits that both ego depletion and unethical behavior can be transmitted from supervisors to subordinates, and that these two crossover processes are entwined with each other.

Creative Mindsets: Scale Validation in the Chinese Setting and Generalization to the Real Workplace.

Creative mindsets reflect the implicit beliefs individuals hold regarding the nature of creativity as innate (i.e., fixed mindset) or malleable (i.

Perceived control moderates the impact of academic stress on the attention process of working memory in male college students.

Academic stress is a common long-term stress among the student population and is known to impact working memory within the frontoparietal attention network. Perceived control is an individual variation that may play a buffering role between stress and overall adjustment. In this study, we addressed the moderating effects of perceived control between academic stress and working memory.

Town mouse or country mouse: identifying a town dislocation effect in Chinese urbanization.

Understanding urbanization and evaluating its impact are vital for formulating global sustainable development. The results obtained from evaluating the impact of urbanization, however, depend on the kind of measurement used. With the goal of increasing our understanding of the impact of urbanization, we developed direct and indirect subjective indicators to measure how people assess their living situation.

Background: The Scale of Positive and Negative Experience (SPANE) is a new instrument that assesses subjective feelings of well-being and ill-being and overcome several limitations of previous popular instruments. The current study examined the scale's psychometric properties with a large Chinese sample.

Principal Findings: Data were collected form 21,322 full-time workers from the power industry.

The efficacy of FMD vaccine reduced non-structural proteins with a mAb against 3B protein.

A monoclonal antibody, 3BIgG, against the prokaryotically expressed foot-and-mouth disease virus (FMDV) non-structural protein (NSP) 3B was obtained. The 3BIgG-sepharose conjugant (3BmAb-6BFF) was prepared by adding the purified 3BIgG into epoxy-activated sepharose 6BFF, incubating with the inactivated FMDV, and then removing the sepharose by centrifugation. The vaccine was made from the supernatant emulsified with oil-adjuvant ISA206.

Progression of the "Psychological Typhoon Eye" and variations since the Wenchuan earthquake.

Background: In 2008 after a massive earthquake jolted Wenchuan, China, we reported an effect that we termed a "Psychological Typhoon Eye": the closer to the center of the devastated area, the lower the level of concern felt by residents about safety and health. We now report on the progression of this effect and the development of new variations after the quake as well as investigating potential explanations.

Methodology/principal Findings: We conducted two sequential surveys of 5,216 residents in non-devastated and devastated areas in September-October 2008 and April-May 2009.

Can overconfidence be debiased by low-probability/high-consequence events?

During the first half of 2008, China suffered three natural disasters: a heavy snow storm, an outbreak of hand-foot-mouth disease, and a severe earthquake. The aim of the present study is to explore how low-probability/high-consequence events influence overconfidence. In Study 1, opportunity samples were obtained by recruiting residents in three different types of disaster-hit areas to answer a peer-comparison probability judgment questionnaire about 1 month after the corresponding disaster occurred.
