This study aims to investigate whether higher value creation leads to higher value appropriation and to identify the boundary conditions in a buyer–supplier relationship that can explain why a particular supplier can appropriate higher value than others.

The study uses questionnaire surveys. The sample of the survey has 150 publicly-listed supplier firms in Taiwan. The unit of analysis is the buyer–supplier relationship.

In the buyer–supplier relationship, suppliers’ bargaining power, partnership and a supplier’s original brand manufacturing (OBM) business can strengthen the positive relationship between value creation and value appropriation.

This study adopts the unilateral viewpoint of suppliers; however, some constructs might require dyadic evaluation. This study only explores the spillover effect of OBM business on the relationship between value creation and appropriation.

The spillover effect of a supplier’s OBM business in a buyer–supplier relationship allows the buyer to share more common benefits and the supplier to capture more private benefits as compensation. By broadening its customer base, a supplier can increase its bargaining power. A supplier can also maintain a strategic partnership with each essential buyer.

To avoid the dark-side effect of partnership, the model provides the contingency that a supplier can capture more value from a buyer–supplier relationship.

This study aims to explore how social media help promote environmental education and pro-environmental behaviours by analysing how young adults access social media and traditional media to obtain environmental information differently, how environmental ideas are disseminated through social media and how people perceive and realise environmentalism.

This is a qualitative study based on a semi-structured interview with student participants. The questions used in the interview were developed by on the integrated waste reduction model by Nishio and Takeuchi (2005) and the enhanced model proposed by Ho et al. (2019).

The results indicate that young adults agree and accept that living environmentally friendly lifestyles is an important goal. Although they acquire environmental information from social media, they seldom share or interact with those social media posts. This behaviour implies that they are information receivers when dealing with such contents.

The finding of this study provides insight for stakeholders on how to promote related knowledge and encourage people to be “greener” more often and construct a friendlier atmosphere for fostering more in-depth environmental discussions on social media.

The rates of emotional distress have risen in many countries during the COVID-19 pandemic. This study assessed the emotional distress of adolescents and young adults in Hong Kong and mainland China in the first year of the pandemic and tested whether spirituality was a protective factor against this emotional distress.

Cross-sectional data were collected in two samples of students aged 17–25 in Hong Kong (N = 503) and 13–20 in mainland China (N = 649). Participants completed the Spiritual Health and Life Orientation Measure (SHALOM) to evaluate their spiritual health (personal-communal, environmental and transcendental domains) and the short form of the Depression, Anxiety and Stress Scale-21 (DASS-21) to assess their emotional distress.

Based on the DASS-21 scores, there was a high rate of adolescents and young adults categorized as showing extremely severe symptoms of depression, anxiety and stress in both Hong Kong and mainland China. Structural equation modeling showed that in both the Hong Kong and mainland China samples the personal and communal and environmental domains of spiritual health were significantly and negatively correlated with all three forms of emotional distress. However, transcendental spiritual health was uncorrelated with psychological distress in Hong Kong and positively correlated with psychological distress in mainland China.

The high rate of severe emotional distress in this sample of adolescents and young adults under COVID-19, and the fact that not all aspects of spiritual health protected again psychological distress are cause for concern, with implications for government, education systems and students.

Healthy spirituality can be found among youths who are upbeat, self-confident, optimistic and constructive and have also been shown to have a higher quality of life in the form of mental, physical and psychological health. The present study is the first study to examine the spiritual and mental health of high school and university students under the impact of COVID-19 in mainland China and in Hong Kong.

The purpose of this paper was to systematically study the electrical properties of 5‐, 42‐ and 75‐nm gap polysilicon structures to evaluate the potentiality of these structures to be used in biomolecular sensing devices.

The authors previously reported the fabrication and morphological characterization of these structures. In this report, they electrically probed the presence of nanogap through current measurement. The effects of electrolytes on the capacitance profiles of these structures were systematically studied with air, water and various dilutions of phosphate buffer saline.

An increment in capacitance was found with the increment in electrolyte concentration. Improvement in current flow, capacitance, permittivity, and conductivity were observed with the smaller size nanogaps, suggesting their applications in low power consuming devices.

Since nanogap‐based dielectric biosensing devices need to be operated with a low level of current to avoid biomolecular damage, these structures should have potential applications in dielectric‐based biomolecular detection using a low cost dielectric analyser.
