Abstract

Purpose

This paper represents the first attempt to examine investor behavior for green stocks through the lens of return co-movement, and provides evidence indicating that green investment practices have gained traction after 2012.

Design/methodology/approach

We empirically test the hypotheses that the stock returns of firms with similar carbon dioxide emissions levels move together and, if so, whether this co-movement has increased over time as people become more “carbon-conscious.” Our baseline sample, based on carbon emissions data from public company disclosures, suffers from limited coverage, particularly before 2016, leading to low statistical power and sample selection bias. To address this, we employ machine learning methodologies to forecast the carbon emissions of firms that do not disclose such information, nearly quadrupling the sample size. Our findings indicate that stocks with similar carbon emissions exhibit higher co-movement in stock returns in both the baseline and augmented data samples. Furthermore, this co-movement has increased during the 2012–2020 period compared to the 2004–2011 period, suggesting that green investment has gained traction over time.

Findings

We find that stocks with similar carbon emissions exhibit higher co-movement in stock returns in both the baseline sample and the augmented data sample, and the co-movement has increased in the 2012–2020 period compared to the 2004–2011 years, suggesting that green investment has gained traction over time.

Originality/value

(1) We use machine learning methodology to augment carbon emissions sample which goes back to 2004. Our approach almost quadruples the original data, enabling large-sample testing. (2) We are the first paper to examine how green companies' stock returns co-move and thus provide complementary results on the research on expected returns and carbon emissions.

Abstract

Purpose

This study aims to investigate the corrosion resistance and electrochemical dissolution behavior of superalloys treated by different oxidation treatments.

Design/methodology/approach

Ni-based superalloys were subjected to oxidation treatment at 1000 °C for 10 h, 1150 °C for 10 h and 1200 °C for 20 h. The microstructure, electrochemical dissolution behavior, elemental distribution, as well as compactness and composition of the oxide layer, were studied.

Findings

The results show that both the thickness and the granular oxide size of the oxide layer on Ni-based superalloys increase with longer oxidation times and higher temperatures. The electrochemical dissolution efficiency of Ni-based superalloys decreases with increasing oxidation time and temperature. The reduced electrochemical dissolution efficiency observed in Ni-based superalloys oxidation-treated at 1200 °C for 20 h is primarily attributed to the thicker oxide layer, which contains the highest Cr oxide content.

Originality/value

The findings contribute to the advancement of recycling and utilization of Ni-based superalloy scrap.

Abstract

Purpose

The study aims to address the gap between leaders’ preventative self-regulatory focus and its impact on Chinese primary care physicians (PCPs) well-being, measured by work–family spillover stress and work exhaustion and on healthcare quality, measured by preventive service delivery and clinical guideline adherence.

Design/methodology/approach

This paper conducted a cross-sectional in-person survey with 38 leaders and 224 PCPs in 38 primary health centers (PHCs) in Jinan, Tianjin, Shenzhen and Shanghai. Guided by the regulatory focus theory, this paper built hierarchical linear regression models to examine the association between the leadership’s regulatory focus and physician burnout, work–family conflict, clinic guideline adherence and preventive service delivery.

Findings

This paper added the knowledge of leadership’s regulatory focus impact on the well-being and medical service quality of PCPs. Prevention regulatory focus of leaders was significantly associated with work exhaustion and physicians’ reported work–family conflict. There is no significant association between leadership’s prevention regulatory focus and PCPs’ preventive service delivery or clinical guideline adherence.

Research limitations/implications

Data on the regulatory focus of PCPs were not collected. Future studies should collect longitudinal data, allowing for exploration of the mechanism.

Practical implications

This paper revealed that PHC leaders should restructure their leadership focus away from preventive regulatory behavior, promoting a team atmosphere and enhancing PCP attitudes, behaviors and well-being.

Social implications

To improve the well-being of PCPs and the quality of medical services, our results recommend a focus on establishing a positive organizational culture and addressing the emotional and professional needs of PCPs. To achieve these aims, policymakers should implement measures that promote a more comprehensive and balanced regulatory focus within PHC institutions. These measures should aim to create an environment that supports physician well-being and enhances the quality of healthcare services. Providing ample resources and support, promoting a collaborative team atmosphere and encouraging open communication are vital to empowering PCPs.

Originality/value

This study examined the preventive regulatory focus of PHC leaders on the well-being and medical service quality of PCPs in China.

Abstract

Purpose

This study aims to report the development and experimental evaluation of two kinds of PANI@semiconductor based photocathodic anti-corrosion coating, for application on stainless steel substrates.

Design/methodology/approach

PANI was in situ chemical polymerized on TiO2 and BiVO4 particles, and FT-IR and SEM/EDS were used to understand the characteristics and elemental distribution of the composite particles. Composite coatings, which consisted of epoxy, PANI@TiO2 or PANI@BiVO4 and graphene, were prepared on the 304L stainless steel. Photoelectrochemical response measurement, electrochemical tests and immersion tests were used to assess the anti-corrosion performance of the prepared coatings in 45°C 3.5 wt.% NaCl solution. And the corrosion protection mechanism was further explained by combining with surface observation.

Findings

The photoelectrochemical response tests revealed the good photocathodic effect of the coatings, and the reversible oxidation-reduction properties of PANI (pseudocapacitive effect) leading to the repeated usage of the coatings. Consequently, the anti-corrosion mechanism of the composite coating is attributed to the physical barrier effect of the coating, the anodic protection effect of PANI and the photocathodic and energy store effect.

Originality/value

These kind coatings could prevent corrosion from day to night for stainless steel, which has great engineering application prospects on stainless steel corrosion protection.

Abstract

Purpose

Construction workers’ safety compliance is attracting considerable critical attention as it plays a decisive role in improving safety on construction sites. This study applied the concept of differentiating safety compliance into deep compliance (DC) and surface compliance (SC) and relied on trait activation theory to investigate the effects of situational awareness (SA) and emotional intelligence (EI) on safety compliance.

Design/methodology/approach

Cross-sectional survey data were collected from 239 construction workers in Australia, and these responses were statistically analyzed using the partial least squares structural equation modeling (PLS-SEM) to validate the proposed model.

Findings

Results revealed that both EI and SA positively impacted DC and negatively impacted SC. Moreover, SA partially mediated the link between EI and two types of safety compliance (DC and SC). The outcomes showed that construction workers’ ability in regulating their emotions could influence their perception of environmental cues and the effectiveness of safety compliance behavior.

Originality/value

This study sheds light on investigating the antecedents of DC and SC from the perspective of trait activation theory. The findings also have practical implications, stating that construction site managers or safety professionals should consider providing training on construction workers’ EI and SA to enhance their willingness to expend conscious efforts in complying with safety rules and procedures, which can lead to improved safety outcomes.

Abstract

Purpose

This paper aims to study the interplay between a risk-averse national brand manufacturer's (NBM) selling mode decision and a risk-neutral e-platform's private brand (PB) introduction decision.

Design/methodology/approach

A game theory model is used to solve selling mode decision, that is whether transform the selling mode from the wholesale mode to the marketplace mode, and PB introduction decision, that is, whether introduce the PB.

Findings

The results show that for the NBM, under certain condition, the NBM's selling mode decision is not affected by the e-platform's PB introduction decision. High revenue-sharing rate is conducive only when the difference in consumer preference between the PB and the national brand (NB) is small. The NBM's risk aversion will improve the applicability of the marketplace mode. For the e-platform, high PB preference of consumers and risk-averse behavior of the NBM is not conducive to PB introduction. For the supply chain, scenarios that the NB monopolizes the market under the wholesale mode and PB introduction under the marketplace mode should be prevented. PB introduction under the wholesale mode will become the only equilibrium with the increase of risk aversion of the NBM. Finally, the authors extend the scenario that consumers prefer the PB and the e-platform is risk-averse enterprise and find that PB introduction under the wholesale mode is detrimental to the NBM but beneficial to the supply chain. The impact of consumers' PB preference on the e-platform's PB introduction is opposite to the basic model. The impact of the e-platform's risk aversion on game equilibrium is opposite to that of the NBM's risk aversion.

Originality/value

This paper is first to study selling mode decision and PB introduction decision when considering enterprises' risk-averse attitude.

This paper aims to explore work interfering with family (WIF) and family interfering with work (FIW) as the mediators linking psychological resilience to happiness.

Abstract

Purpose

This paper aims to explore work interfering with family (WIF) and family interfering with work (FIW) as the mediators linking psychological resilience to happiness.

Design/methodology/approach

Data gathered from tour guides in Türkiye were used to test the aforesaid associations. In this paper, partial least squares structural equation modeling was performed to gauge the direct links and mediating impacts of WIF and FIW simultaneously in the link between psychological resilience and happiness.

Findings

Psychological resilience exerts a dual influence on WIF and FIW. Simply put, psychologically resilient tour guides balance their work demands with those of the family or vice versa and exhibit low levels of WIF and FIW. As hypothesized, WIF and FIW are the two mediating mechanisms relating psychological resilience to happiness.

Practical implications

It is important to create a family-supportive atmosphere where tour guides can avail themselves of family-friendly practices (i.e. family leave, flexible work schedules, breaks to be spent with family members after long tours and convenient working hours). Psychologically resilient tour guides, with the abovementioned practices, would experience alleviated conflicts between work and family roles and would therefore have heightened happiness.

Originality/value

Although the extant literature has presented plenty of empirical studies about the predictors and outcomes of WIF and FIW, evidence about the links of personal resources as third variables to WIF and FIW simultaneously is still scanty. In addition, there is no evidence linking personal resources such as psychological resilience to nonwork outcomes such as happiness through the mediating roles of WIF and FIW. This paper fills in these voids by gauging the links given above using data collected from tour guides, a population that has been subjected to limited inquiry in the WIF and FIW literature.

Abstract

Purpose

The aim was not to perform a systematic review but firstly to search in PubMed, Science Direct, Scopus and Web of Science databases on the papers published in the last five years using tools for reviewing the statement of preferred information item for systematic reviews without focusing on a randomized analysis and secondly to perform a bibliometric analysis on the properties of films and coatings added of tocopherol for food packaging.

Design/methodology/approach

On January 24, 2022, information was sought on the properties of films and coatings added of tocopherol for use as food packaging published in PubMed, Science Direct, Scopus and Web of Science databases. Further analysis was performed using bibliometric indicators with the VOSviewer tool.

Findings

The searches returned 33 studies concerning the properties of films and coatings added of tocopherol for food packaging, which were analyzed together for a better understanding of the results. Data analysis using the VOSviewer tool allowed a better visualization and exploration of these words and the development of maps that showed the main links between the publications.

Originality/value

In the area of food science and technology, the development of polymers capable of promoting the extension of the shelf life of food products is sought, so the knowledge of the properties is vital for this research area since combining a biodegradable polymeric material with a natural antioxidant active is of great interest for modern society since they associate environmental preservation with food preservation.

Abstract

The recent COVID-19 pandemic underscores the need for educational innovation and digitalization during crises where many educational institutions were forced to shift to online and remote learning. This chapter is a discursive review of problems and solutions and key trends that have emerged because of crises. One of the key benefits of educational innovation and digitalization during crises is the ability to continue providing education and learning opportunities to students even when traditional face-to-face learning is not possible. Educational institutions need to invest in building resilient online learning ecosystems to ensure that education can continue uninterrupted even in the face of unforeseen disruptions. This ecosystem should include robust technological infrastructure, a diverse range of digital resources and tools, and training and support for educators. Ultimately, a resilient online learning ecosystem is not just a response to crises but a proactive investment in the future of education.
