Design and synthesis of esterase-activated fluorescent probe for diagnosis and surgical guidance of liver cancer.

Liver cancer seriously threatens the health of human beings. Studies have found that esterase is overexpressed in liver cancer cells. Therefore, esterase can be one of the biomarkers of liver cancer.

Structural superlubricity at the interface of penta-BN.

Two-dimensional (2D) materials have been widely used as lubricants due to their weak interlayer interaction and low shear resistance for interlayer sliding. Composed entirely of five-membered rings, penta-BN monolayer has excellent thermal and mechanical stability, higher hardness and a negative Poisson's ratio. In this work, we investigate the frictional properties at both the commensurate and incommensurate contacting interfaces of penta-BN by adopting the molecular dynamics (MD) simulation method.

Decoding the research landscape of drug resistance and therapeutic approaches in head and neck cancer: a bibliometric analysis from 2000 to 2023.

Introduction: Head and neck cancer is one of the most common tumors worldwide. However, drug resistance in its treatment has become a major factor limiting the efficacy. This study aims to comprehensively understand the current status of research in this field.

Preretirement resources and postretirement life satisfaction change trajectory: Examining the mediating role of retiree experience during retirement transition phase.

Successfully adjusting to retirement represents a major challenge for many older workers. Following the temporal unfolding of retirement process (i.e.

The Psychological Consequences of the COVID-19 on Residents and Staff in Nursing Homes.

In this commentary, we overview the existing research on psychological consequences caused by COVID-19 for both residents and staff in the nursing homes. We identify loneliness and emotional anxiety as main psychological consequences for nursing home residents, whereas uncertainty, hopelessness, work overload, and role conflicts are the most salient psychological challenges for the staff in the nursing homes during the pandemic. We then summarize the existing strategies and interventions responsive to the above challenges.

Designing Self-Sustainable Icephobic Layer by Introducing a Lubricating Un-Freezable Water Hydrogel from Sodium Polyacrylate on the Polyolefin Surface.

A convenient, environment-friendly, and cost-effective method to keep anti-icing for a long time was highly desirable. Slippery lubricant layers were regarded to be effective and promising for anti-icing on different surfaces, but the drought-out of lubricants and the possible detriments to the environment were inevitable. By combining super-high molecular weight sodium polyacrylate (H-PAAS) with polyolefin through a one-pot method, a self-sustainable lubricating layer with extremely low ice adhesion of un-freezable water hydrogel was achieved at subzero conditions.

Measurement invariance of the moral vitalism scale across 28 cultural groups.

Moral vitalism refers to a tendency to view good and evil as actual forces that can influence people and events. The Moral Vitalism Scale had been designed to assess moral vitalism in a brief survey form. Previous studies established the reliability and validity of the scale in US-American and Australian samples.

Explaining illness with evil: pathogen prevalence fosters moral vitalism.

Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens.

A self-regulation perspective on how and when regulatory focus differentially relates to citizenship behaviors.

Although previous research suggests that regulatory focus matters for organizational citizenship behaviors, it is unclear how promotion and prevention focus relate to such behaviors. Integrating regulatory focus theory with theories of self-regulation, we propose a conceptual model that links trait promotion and prevention foci with specific citizenship behaviors through an emotion-related self-regulation mechanism. Using a sample of 227 nurses working in a hospital context, we observed that trait promotion focus and trait prevention focus predict helping and voice via differential effects on emotional exhaustion.

Relationship Between Immune Parameters and Non-alcoholic Fatty Liver Disease in Obese Children.

Objective: To investigate the relationship between immune parameters and non-alcoholic fatty liver disease (NAFLD) in obese children.

Design: Cross-sectional study.

Setting: Hospital-based study in Zhejiang Province, China between July to September 2015.

Eating your feelings? Testing a model of employees' work-related stressors, sleep quality, and unhealthy eating.

Although organizational research on health-related behaviors has become increasingly popular, little attention has been paid to unhealthy eating. Drawing on the self-regulation perspective, we conducted 2 daily diary studies to examine the relationships between work-related stressors, sleep quality, negative mood, and eating behaviors. Study 1 sampled 125 participants from 5 Chinese information technology companies and showed that when participants experienced higher levels of job demands in the morning, they consumed more types of unhealthy food and fewer types of healthy food in the evening.

Nonlinear effects of team tenure on team psychological safety climate and climate strength: Implications for average team member performance.

The teams literature suggests that team tenure improves team psychological safety climate and climate strength in a linear fashion, but the empirical findings to date have been mixed. Alternatively, theories of group formation suggest that new and longer tenured teams experience greater team psychological safety climate than moderately tenured teams. Adopting this second perspective, we used a sample of 115 research and development teams and found that team tenure had a curvilinear relationship with team psychological safety climate and climate strength.

Retirees' motivational orientations and bridge employment: Testing the moderating role of gender.

Bridge employment refers to the labor force participation after people retire from career jobs. It is becoming a prevalent phenomenon for retirees transitioning from employment to complete work withdrawal. Building on existing literature on retirement transition and older adults' work motivation, the present study examined the effects of 3 motivational orientations (i.

Work-family conflict, emotional exhaustion, and displaced aggression toward others: the moderating roles of workplace interpersonal conflict and perceived managerial family support.

Taking a resource-based self-regulation perspective, this study examined afternoon emotional exhaustion as a mediator linking the within-person relations between morning work-family conflict and later employee displaced aggression in the work and family domains. In addition, it examined resource-related contextual factors as moderators of these relations. The theoretical model was tested using daily diary data from 125 employees.

Self-regulation during job search: the opposing effects of employment self-efficacy and job search behavior self-efficacy.

Adopting a self-regulatory perspective, the current study examined the within-person relationships among job search cognitions, job search behaviors, and job search success (i.e., number of job offers received).

Do Job Demands of Chinese Manufacturing Employees Predict Positive or Negative Outcomes? A Test of Competing Hypotheses.

Karasek's job demands-control (JDC) model posits that job control can buffer against the harmful effects of demands experienced by employees. A large volume of JDC research has obtained support for the main effects of demands and control, but not the interactive effects. Recent research on the challenge-hindrance stressors framework, however, found that work stressors may not always be deleterious, suggesting alternative hypotheses about the effects of demands and control.

Can't get it out of my mind: employee rumination after customer mistreatment and negative mood in the next morning.

Drawing on cognitive rumination theories and conceptualizing customer service interaction as a goal attainment situation for service employees, the current study examined employee rumination about negative service encounters as an intermediate cognitive process that explains the within-person fluctuations in negative emotional reactions resulting from customer mistreatment. Multilevel analyses of 149 call-center employees' 1,189 daily surveys revealed that on days that a service employee received more (vs. less) customer mistreatment, he or she ruminated more (vs.

Psychological research on retirement.

Retirement as a research topic has become increasingly prominent in the psychology literature. This article provides a review of both theoretical development and empirical findings in this literature in the past two decades. We first discuss psychological conceptualizations of retirement and empirical operationalizations of retirement status.

The moderating role of attachment anxiety on social network site use intensity and social capital.

This study examined the moderating role of attachment anxiety on the relationship between intensity of social network site use and bridging, bonding, and maintained social capital. Data from 322 undergraduate Chinese students were collected. Hierarchical regression analyses showed positive relationships between online intensity of social network site use and the three types of social capital.

Linking subordinate political skill to supervisor dependence and reward recommendations: a moderated mediation model.

In this study, we examined the relations of subordinate political skill with supervisor's dependence on the subordinate and supervisor reward recommendation, as well as mediating (interaction frequency with supervisor) and moderating (supervisor political behavior) variables of these relations. Our theoretical model was tested using data collected from employees in a company that specialized in construction management. Analyses of multisource and lagged data from 53 construction management team supervisors and 296 subordinates indicated that subordinate political skill was positively related to supervisor reward recommendation via subordinate's interaction frequency with supervisor.

Work-family conflict and job satisfaction: emotional intelligence as a moderator.

The negative impact of work-family conflict (WFC) on employees' well-being and job-related outcomes has attracted much research attention recently. A major gap in the literature is which factors could potentially buffer its negative effect on employees. The present study examined the moderating effect of emotional intelligence on the relationship between WFC and job satisfaction in a sample of 212 Chinese high school teachers.

Psychometric properties of a Chinese translation of the political skill inventory.

Ferris and colleagues defined political skill in organizations as "the ability to effectively understand others at work and to use such knowledge to influence others to act in ways that enhance one's personal and/or organizational objectives." In this study, the psychometric properties of a Chinese translation of the Political Skill Inventory were investigated, supporting construct, convergent, discriminant, and criterion validities. The results suggested that the Chinese translation retained a four-factor structure.

Supervisors' upward exchange relationships and subordinate outcomes: testing the multilevel mediation role of empowerment.

This study empirically examined the proposition that supervisors' exchange relationships with their own supervisors (i.e., leader-leader exchange, or LLX) are related to their subordinates' work-related outcomes through 3 mechanisms: (a) leaders modeling their LLX to develop and maintain their exchange relationships with their subordinates (i.
