Abstract
Purpose
This study's main goal is to expand the theoretical perspective and discuss the unique influence of age and tenure on R&D teams' incremental innovation outcomes. We answer scholars call for additional research on age-related processes by testing pathways through which older employees can benefit organizational performance. The current study advances the literature by relating to the context-related process of cohesion and investigating its moderating influence on the relationship between team antecedents (i.e. age and tenure) and incremental innovation.
Design/methodology/approach
This research sample consists of 108 R&D teams operating in six mature high-tech organizations located in Israel. The participating entities design and manufacture state-of-the-art innovations in the semiconductors, communications and information technology sectors. The number of teams in each participating entity was 35, 21, 21, 19, 7 and 5, respectively. The sample consisted of 443 R&D employees and 212 team leaders/managers. The total sample comprised 655 participants. Team members filled out questionnaires to assess the independent variables. The dependent-variable questionnaire focusing on the team's incremental innovation accomplishments was completed by two managers for each team.
Findings
We found a negative association between team members' age and incremental innovation. Hypothesis 2, which predicted a positive association between team members' tenure and incremental innovation, was marginally supported. The interaction between team members' age and team members' tenure on incremental innovation was marginally supported. Hypothesis 4, which predicted that the negative association between team members' age and incremental innovation would be mitigated when the level of team cohesion is low, was supported. Hypothesis 5, which assumed that the positive association between team members' tenure and incremental innovation would be stronger when the level of cohesion is high, was supported.
Practical implications
This research's results regarding the negative influence of R&D employees' age on incremental innovation are crucial for managers and team leaders in the high-tech industry. Following the age stereotype, many of them avoid recruiting and assigning older employees to R&D teams dealing in innovation creation and development. They should expand their perspective and consider additional attributes in order to assign the employees that best match the team's mission. The results show that R&D teams produce high and similar levels of incremental innovation when the level of team members' tenure is high, regardless of their age.
Originality/value
This study benefited from a relatively high number of respondents and teams from leading high-tech organizations, a high response rate and a research design that made it possible to establish a linkage between data on the independent variables and data on incremental innovation collected from separate independent sources. The data on the dependent variable—incremental innovation—was based on independent assessments made by two managers for each team. The study's measurements were based on leading studies on innovation.

The purpose of this study is to investigate whether and how inter-firm cooperation and firm age moderate the relationship between family ownership and productivity.
Abstract
Purpose
The purpose of this study is to investigate whether and how inter-firm cooperation and firm age moderate the relationship between family ownership and productivity.
Design/methodology/approach
We first estimate the total factor productivity (TFP) of a large sample of Italian firms observed over the period 2010–2018 and then apply a Poisson random effects model.
Findings
TFP is, on average, higher for non-family firms (non-FFs) than for FF. Furthermore, inter-organizational cooperation and firm age mitigate the negative effect of family ownership. In detail, it is found that belonging to a network acts as a moderator in different ways according to firm age. Indeed, young FFs underperform non-FF peers, although the TFP gap decreases with age. In contrast, the benefits of a formal network are high for older FFs, suggesting that an age-related learning process is at work.
Practical implications
The study provides evidence that FFs can outperform non-FFs when they move away from Socio-Emotional Wealth-centered reference points and exploit knowledge flows arising from high levels of social capital. In the case of mature FFs, networking is a driver of TFP, allowing them to acquire external resources. Since FFs often do not have sufficient in-house knowledge and resources, they must be aware of the value of business cooperation. While preserving the familiar identity of small companies, networks grant FFs the competitive and scale advantages of being large.
Originality/value
Despite the wide but ambiguous body of research on the performance gap between FFs and non-FFs, little is known about the role of FFs’ heterogeneity. This study has proven successful in detecting age as a factor in heterogeneity, specifically to explain the network effect on the link between ownership and TFP. Based on a representative sample, the study provides a solid framework for FFs, policymakers and academic research on family-owned companies.

Abstract
Purpose
We investigated the relationship between personality and managerial assessment center (AC) dimensions, emphasizing age’s moderating role within volatility, uncertainty, complexity, ambiguity (VUCA) simulations.
Design/methodology/approach
We analyzed 327 managers and applied the AC method, examining areas like social skills, problem-solving, management and goal striving, openness to change, employee development using the VUCA framework.
Findings
We assessed personality metatraits through a questionnaire based on the circumplex model (CPM; Strus, Cieciuch, & Rowinski, 2014), identifying four bipolar metatraits. Results highlighted passiveness and disharmony as negatively correlated with all managerial AC dimensions, with passiveness adversely affecting social skills and problem-solving.
Originality/value
Age’s moderating role emerged as pivotal in the relationship between personality and managerial AC dimensions, especially in specific VUCA contexts. This underscores age’s influence on the interplay between personality and managerial efficacy, suggesting varying predictive capabilities across age groups. The research illuminates the complexities of these relationships, spotlighting age’s nuanced impact.

Abstract
Purpose
This study aims to investigate the relationships between the perceived neighborhood walkable environment (PNWE), neighborhood interaction (NI) and residents’ mental health, with a focus on examining differences among residents of different age groups.
Design/methodology/approach
Using an electronic survey questionnaire, data on PNWE, NI and mental health were collected from 1,159 residents across 205 communities in Shanghai, China. Our study utilized a structural equation modeling (SEM), employing the maximum likelihood estimation method. The structural equation model was fitted using the MPLUS software.
Findings
The mental health of young and middle-aged adults is generally poor, and they are at higher risk of depression than children and older adults. The effects of PNWE and NI on the mental health of residents varied among different age groups. As residents get older, their mental health is more affected by the PNWE. In addition, the influence of the PNWE on children and older adults’ mental health is direct and not mediated by NI. For young and middle-aged adults, the influence of the PNWE on their mental health needs to be mediated by NI.
Originality/value
This study marks the first examination of the relationship between PNWE, NI and mental health among different age groups of residents in China. The findings of this research can assist policymakers in gaining a deeper understanding of the underlying mechanisms by which PNWE affects mental health. Furthermore, it can contribute to the development of more targeted walkable environment designs aimed at enhancing mental health among various age groups.

Abstract
Purpose
Ageism has deleteriously influenced individuals and society for nearly half a century. Despite receiving increased attention, it remains under-researched regarding how it might be reduced in the workplace. Even though its prevalence and allure, review studies on workplace ageism (WA) are also scarce, and thus a review is warranted.
Design/methodology/approach
To fill the preceding void, this study will systematically review the existing literature on WA using data from the past four decades.
Findings
This study identified the various antecedents and the intervention mechanism through which WA may be reduced. Additionally, through reviews, the authors advance the research by offering promising avenues for future research.
Originality/value
This review contributes to human resources managers and will inspire future scholars to delve deeper into combating age discrimination, stereotypes and bias toward employees in workplaces.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Practical implications
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.
Originality/value
The paper shows the relationship between aging and the home environment and how building design considerations could enhance healthy aging-in-place.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Originality/value
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.

Abstract
Purpose
This paper aims to investigate the effects of second phase precipitate size on microstructure, hardness, density, corrosion and electrical conductivity of 7075 aluminum alloy fabricated by the powder metallurgy method and aged at 120°C for various aging periods.
Design/methodology/approach
For the aging process (T6), these alloys were solution-treated at 485°C for 2 h, quenched, aged at 120°C for four various periods and finally air cooled. After the aging process, these alloys were examined with scanning electron microscope, X-ray diffraction, density and hardness measurements. The corrosion tests were carried out using the potentiodynamic polarization technique; electrical conductivity values were measured as IACS%.
Findings
Results showed that the precipitate size increased with increasing aging period and the maximum precipitate size was achieved for the sample aged for 28 h. The maximum hardness was attained for the sample aged for 24 h, while the same specimen obtained the lowest electrical conductivity and corrosion resistance.
Originality/value
In this research, second phase precipitates of heat treatment processing affected the electrical conductivity and corrosion behavior of the 7075 aluminum alloy. Also it is understood that the heat treatment period is an effective parameter on these properties.

Abstract
Age discrimination is common and occurs in all types of industries, fields, and professions all across the world. The common misperceptions about “older workers” include hard‐to‐break habits, technological ignorance, and lack of energy and flexibility. Such attitudes, expectations, and perceptions of older workers should not exist in our professional community. Whether old or young, all people should be treated with respect and dignity. The purpose of this article is to understand the reasons behind age discrimination and ways to prevent it from occurring in the workplace. Removing age discrimination in the workplace lies in the hands of all organisations. First, they need to demolish the myths of age and realise its strengths, such as reliability, mature judgement, lack of impulsivity, timeliness, strong work ethics, and experience. Second, upper management should educate its chain of managers and supervisors about the effects discrimination has on the company’s financial situation as well as its reputation. The government plays a major role in enforcing the laws regarding age discrimination and punishing those who are unlawful.

Abstract
Analyses the effects of age on the level of job satisfaction of accountants in Singapore. Four categories of accountants namely, government auditors, internal auditors, non‐auditor accountants, and external auditors were identified according to the nature of work performed by each, i.e. job‐type. Results of a three‐way analysis of variance (ANOVA) show that both age and job type, taken individually, have a direct significant effect on job satisfaction. In addition, there is also an interaction effect between age and job‐type on job satisfaction. In general, older accountants are more satisfied with their jobs than their younger counterparts. However their satisfaction increases at varying rates depending on their job types.
