The aging population, a higher proportion of older adults (aged 65+), is considered a global and severe problem, while the information systems (IS) literature on detecting the relationship between the aging population and the development of electronic commerce (e-commerce) is limited and insufficient. Hence, the main objective of this paper is to examine whether an aging population can moderate the effect of infrastructure constructions on e-commerce sales and whether an aging population can affect e-commerce sales.

To investigate the relationship between the aging population and e-commerce sales, this study proposes two potential influential mechanisms: moderating the effects of infrastructure development on e-commerce sales and direct influence. Subsequently, a sample of 31 Chinese provinces from 2013 to 2019 is utilized to conduct regression analyses in order to examine these hypotheses.

The findings suggest that the development of urban transportation infrastructure and network constructions can significantly contribute to the enhancement of e-commerce sales, and the influence cannot be affected by aging population. Furthermore, it is noteworthy that an aging population can have a positive effect on e-commerce sales.

The findings can inform future infrastructure constructions by assessing the potential of infrastructure projects to boost e-commerce sales and examining whether this effect varies in an aging population context.

The findings substantiate the pivotal role of older adults in the e-commerce industry. Moreover, the obtained results establish a positive relationship between an aging population and e-commerce sales, thereby offering diverse perspectives on existing theories.

The concept of aging-in-place has gained notable significance in the last decade due to a dramatic demographic shift in global population dynamics that have considerably affected the ability of societies to adequately cater for their aging population. This paper examines some of the barriers to aging-in-place in the context of health needs, housing design and the role of retrofitting/smart home technologies in overcoming these barriers.

Using a narrative literature review approach, the authors undertook a comprehensive search of recent relevant literature focusing on five core thematic areas: health and aging, aging in place, barriers to aging in place, retrofitting and smart home technologies for successful aging in place. The authors entered appropriate keywords into interdisciplinary research databases and synthesized a coherent narrative discussing the thematic areas using the data extracted from the literature search.

There is a bidirectional relationship between aging and the home environment. Barriers to aging-in-place are mainly related to progressive decline in health, which alters the environmental needs of individuals. Appropriate building designs can significantly facilitate aging-in-place. The authors, therefore, highlight the role of retrofitting and smart home technologies as practical solutions to the challenges of the aging-in-place.

Forward planning in building design is essential to guarantee that the home environment is well adapted for the challenges of aging-in-place while also promoting healthy aging.

The paper shows the relationship between aging and the home environment and how building design considerations could enhance healthy aging-in-place.

The service environment of urban polyethylene (PE) pipes has a crucial influence on their long-term safety and performance. Based on the application and structural performance analysis of PE pipe failure cases, this study aims to investigate the impact of organic substances in the soil on the aging behavior of PE pipes by designing organic solutions with different concentrations, which are based on the composition of organic substances in the soil environment, and periodic immersion tests.

Soil samples in the vicinity of the failed pipes were analyzed by gas chromatography-mass spectrometry, sensitive organic substances were screened and soaking solutions of different concentrations were designed. After the soaking test, the PE pipe samples were analyzed using differential scanning calorimetry, Fourier-transform infrared spectroscopy and other testing methods.

The performance difference between the outer surface and the middle of the cross section of PE pipes highlights the influence of the soil service environment on their aging. Different organic solutions can have varying impacts on the aging behavior of PE pipes when immersed. For instance, when exposed to amine organic solutions, PE pipes may have an increased weight and decreased material yield strength, although there is no reduction in their thermal or oxygen stability. On the contrary, when subjected to ether organic solutions, the surface of PE pipe specimens may be affected, leading to a reduction in material fracture elongation and a decrease in their thermal and oxygen stability. Furthermore, immersion in either amine or ether organic solutions may result in the production of hydroxyl and other aging groups on the surface of the material.

Understanding the potential impact of organic substances in the soil environment on the aging of PE pipe ensures the long-term performance and safety of urban PE pipe. This research approach will provide valuable insights into improving the durability and reliability of urban PE pipes in soil environments.

The anticorrosion coatings used in marine and atmospheric environment are subjected to many environmental factors. And the aging failure has been puzzling researchers. The purpose of this study is to find the correlation between the initial aging of epoxy coatings and the typical marine atmospheric environmental factors.

The epoxy coatings were subjected to a one-year exposure in three typical marine atmospheres. Meanwhile, principal component analysis, linear regression and Spearman and gray correlation analysis were applied to quantify the environmental characteristics and establish correlations with the coating aging.

The results indicate that the coating will undergo macroscopic fading and chalking upon exposure to the marine atmosphere, while microscopic examination reveals holes, cracks and partial peeling. The adhesion performance and electrochemical properties of the coating deteriorated with prolonged exposure, coating aging mainly occurs with the generation of O-H bonds and the breakage of molecular chains such as C-N and C-O-C. The coating was most deeply aged after exposure to the Xisha, followed by Zhoushan and finally Qingdao. Environmental factors affect the photooxidative aging and hydrolytic degradation processes of coatings and thus coating aging. To further demonstrate the correlation between environmental factors and coating aging, principal component analysis was used. The correlation model between environmental factors and coating aging was subsequently obtained. The correlation model between the rate of coating adhesion loss (E) and the comprehensive evaluation parameter of environmental factors (Z) is expressed as E = 0.142 + 0.028Z. Meanwhile, the Spearman correlation analysis and gray correlation method were used to investigate the impact of each environmental factor on coating aging. Solar irradiation, relative humidity and wetting time have the highest correlation with coating aging, which are all above 0.8 and have the greatest influence on coating aging; wind speed and temperature have the smallest correlation with coating aging, which are about 0.6 and have the least influence on coating aging.

This paper establishes a correlation between typical marine environmental factors and coating aging performance, which is crucial for predicting the service life of other coatings in diverse environments.

The Organization for Economic Cooperation and Development (OECD) countries are facing unprecedented challenges related to climate change and population aging. The purpose of the analysis is to explore the relationship between population aging and environmental degradation, accounting for human capital, using a sample of 19 OECD countries over the period 1980–2019.

On the empirical methodology, the analysis uses panel estimators with heterogenous coefficients and an error structure that takes into consideration cross-country heterogeneity and cross-sectional dependence for a panel of 19 OECD countries over the period 1980–2019. To examine the relationship between population aging and environmental degradation, the authors employ two alternative measures of environmental degradation that is energy consumption and CO2 emissions in metric tons per capita. Concerning the regressors, the authors account for two alternative aging indicators, namely the elderly population and the old-age dependency ratios to confirm robustness.

The analysis provides evidence that population aging and human capital development (IHC) lead to lower energy consumption in the OECD sample. Overall, the growing number of elderly people in the OECD seems to act as a mitigating factor for energy consumption. The authors view these results as conveying the message that the evolution of population aging along with channeling government expenditures towards human capital enhancement are important drivers of curbing energy consumption and ensuring environmental sustainability. The authors' research is of great significance for environmental policymakers by illuminating the favorable energy consumption patterns that population aging brings to advanced economies.

The main limitation of this study concerns data availability. Future research, and subject to greater data availability in the future, could dig deeper into understanding the dynamics of this complex nexus by incorporating additional control variables. Similarly, the authors focus on aggregate renewable energy consumption, and the authors do not explicitly model the sources of renewable energy (wind, hydropower, solar power, solid biofuels and other). Additional analysis of the breakdown of renewable energy sources would be insightful – subject to data availability – especially for meeting the recently agreed new target of 42.5% for European Union (EU) countries by 2030. A deep transformation of the European energy system is needed for the EU to meet the target. Finally, extending the model to include a range of non-OECD countries that are also experiencing demographic transformations is a promising avenue for future research.

To the best of the authors' knowledge, this study is the first to examine the effects of population aging and human capital on environmental degradation using a broad set of OECD countries and advanced spectrum estimation methods. Given cross-sectional dependencies and cross-country heterogeneity, the authors' empirical results underline the importance of cross-OECD policy spillovers and knowledge diffusions across the OECD countries. The new “energy culture” calls for concerted policy action even in an aging era.

This paper aims to investigate the ability of traditional biopolymers, such as funori or the nanoscale form of cellulose nanocrystals, to consolidate fragile paper and preserve it for as long as possible.

Degraded papers dating back two centuries were separated into paper samples for consolidation processes. Funori – a marine spleen – was used as a traditional consolidation material and a mixture with ZnO NPs compared with modern materials, such as cellulose nanocrystals. The samples were aged for 25 years, examinations and analyses were performed using scanning electron microscopy and color change was assessed using the CIELAB system, X-ray diffraction and Fourier-transform infrared spectroscopy.

According to the results, using traditional materials to consolidate damage, such as funori, after aging resulted in glossiness on the surface, a color change and increased water content and oxidation. Furthermore, samples treated with a mixture of ZnO NPs and funori revealed that the mixture improved the sample properties and increased the degree of crystallization. Cellulose nanocrystals improved the surface, filled gaps, formed bridges between the fibers and acted as a protector from aging effects.

This paper highlights the ability of nanomaterials to enhance the properties of materials as additives and treat the paper manuscripts from weaknesses.

This paper aims to examine two types of age-related human resources (HR) practices, i.e. age-specific and age-inclusive HR practices and firm-level (meso-level) factors that foster or hinder the implementation of these two types of practices.

Based on a cross-case analysis of four firms across industries in Thailand, a developing country, the empirical evidence draws on semi-structured interviews with the top managers, HR managers and aging employees of four firms; field visits; nonparticipant observations; and a review of archival documents and Web-based reports and resources.

This paper proposes that age-specific HR practices primarily include those HR practices under the regulation HR bundle and some HR practices under the maintenance and recovery HR bundles. Additionally, the factors fostering the implementation of age-specific HR practices in firms include group corporate culture, nonunionism within the workplace, paternalistic leaders, a focus on the development of internal labor markets within firms and the need for tacit knowledge transfer from aging employees to younger-generation employees, whereas the factors hindering the implementation of age-specific HR practices in firms include age biases within firms. Moreover, age-inclusive HR practices primarily include HR practices under the development HR bundle and some HR practices under the maintenance and recovery HR bundles. Additionally, the factors fostering the implementation of age-inclusive HR practices in firms include the procedural justice climate, the transition from a family ownership structure to a professional ownership structure and result-/output-based corporate culture, whereas the factors hindering the implementation of age-inclusive HR practices in firms include experience-/seniority-based corporate culture. In fact, some of the meso-level factors that foster or hinder the implementation of age-specific and age-inclusive HR practices tend to be influenced by the national institutional and cultural contexts of the developing country where firms that implement such HR practices are located.

This paper aims to fill the research gap by examining both age-specific and age-inclusive HR practices. Additionally, this paper analyzes the factors fostering or hindering the implementation of these two dimensions of age-related HR practices across firms by using a case study of firms in Thailand, a developing country. To date, most studies in this area have focused on one of these dimensions, while comparisons between different HR dimensions are rather scarce. Finally, this paper contributes to the prior literature on strategic HR and comparative institutional perspective on HR strategies and practices as proposed by Batt and Banerjee (2012) and Batt and Hermans (2012) that future research should go beyond the meso-level (organizational) context. In this regard, some of the factors that foster or hinder the implementation of age-specific and age-inclusive HR practices tend to be influenced by the national institutional and cultural contexts of the developing country of Thailand.

The color painting of ancient buildings has high historical and artistic value but is prone to aging due to long-term outdoor exposure. The purpose of this study is to develop a new type of sealing coating to mitigate the impact of ultraviolet (UV) light on color painting.

The new coating was subjected to a 500-h UV-aging test. Compared with the existing acrylic resin Primal AC33, the UV aging behavior of the new coating, such as color difference and gloss, was studied with aging time. The Fourier infrared spectra of the coatings were analyzed after the UV-aging test.

Compared with AC33, the antiaging performance of SF8 was substantially improved. SF8 has a lower color difference value and better light retention and hydrophobicity. The Fourier transform infrared spectroscopy results showed that the C-F bond and Si-O bonds in the resin of the optimized sealing coating protected the main chain C-C structure from degradation during the aging process; thus, the resin maintained good stability. The hindered amine light stabilizer TN292 added to the coating inhibited the antiaging process by trapping active free radicals.

To address the problem of UV aging of oil-decorated colored paintings, a new type of sealing coating with excellent antiaging properties was developed, laying the foundation for its demonstration application on the surface of ancient buildings.

This study aims to investigate the impacts of pandemic-related media coverage on younger hospitality and tourism employees’ ageist attitudes toward older people by applying the media priming theory and the terror management theory.

This study takes a mixed-method approach through an online survey. A total of 416 usable responses are collected from current US hospitality and tourism employees under 55 years. Qualitative data were analyzed using word cloud. Partial least squares structural equation modeling is then used to test the hypothesized model.

The study’s results show that younger employees' cognitive reaction negatively affects aging anxiety and intergenerational tension, which subsequently influence their willingness to work with older people. Negative media-induced emotions are positively associated with aging anxiety, whereas positive emotions exert no significant impact. Intergenerational contact frequency moderates the effect of intergenerational tension on younger employees’ willingness to work with older people.

This study’s findings contribute to the hospitality and tourism workforce literature by considering the priming effects of media coverage on younger employees’ attitudes toward self-aging and the older group. This study also offers managerial insights on developing effective age-inclusion interventions to reduce workplace ageism in the post-pandemic era.

Existing hospitality and tourism studies on older workers are scant and largely descriptive. To the best of the authors’ knowledge, this study is the first study that assesses the effects of pandemic-related media coverage on workplace ageism toward older people among the current hospitality and tourism workforce.

The purpose of this paper is to meet Dr Joyce Shaffer, PhD, ABPP, Clinical Associate Professor at the University of Washington.

This case study is presented in two sections: a positive autoethnography written by Joyce Shaffer, followed by her answers to ten questions.

In this positive autoethnography, Shaffer shares her life story and reveals numerous mental health and positive aging recommendations and insights for us to reflect on.

This is a personal narrative, albeit from someone who has been a clinical psychologist and active in the field of aging for many decades.

A pragmatic approach to aging is recommended. According to Shaffer, “those of us who can recognize the beat of the historical drummer can harvest the best of it and learn from the rest of it.”

Positive aging has strong social implications. Shaffer considers that it is not only about maximizing our own physical, mental, emotional and social health but also about maximizing that of others, to make our world a better place for everyone.

Positive aging can be experienced despite adversity. As Shaffer says, “Adversity used for growth and healed by love is the answer.”
