The COVID-19 pandemic caused major disruption in community support for vulnerable older people and is thought to have exacerbated existing issues within UK adult social care. This study aims to examine the legacy of that disruption on how meeting centres for people affected by dementia have been impacted in continually evolving circumstances.

Semi-structured interviews and focus group discussions were conducted at three meeting centre case study sites. Ninety-eight participants, including people living with dementia, family carers, staff, volunteers, trustees and external partners, were asked about the impact and legacy of the pandemic upon meeting centres. A thematic analysis was carried out on the data.

Ten themes were identified: ability to re-open venues; increased health decline and loss of members due to isolation; closure or halting of linking services and dementia community support; disruption to diagnosis and referrals; increase in outreach, building communities and overall reach; digital access and use of technology (boom and decline); changes to carer involvement and engagement; continued uncertainty and changes to funding, resources and governance; staff and volunteer recruitment issues; and relief at/wish for return to pre-pandemic norms.

This paper offers new insight into a still-developing situation, namely, the legacy effects of the pandemic upon third-sector community support for people affected by dementia and the health and social care services that support it. The reduction in maintenance of pandemic-era technological innovations is a key finding.

Supply chains (SCs) have been growingly virtualized in response to the market challenges and opportunities that are presented by new and cost-effective internet-based technologies today. This paper designed a virtual closed-loop supply chain (VCLSC) network based on multiperiod, multiproduct and by using the Internet of Things (IoT). The purpose of the paper is the optimization of the VCLSC network.

The proposed model considers the maximization of profit. For this purpose, costs related to virtualization such as security, energy consumption, recall and IoT facilities along with the usual costs of the SC are considered in the model. Due to real-world demand fluctuations, in this model, demand is considered fuzzy. Finally, the problem is solved using the Grey Wolf algorithm and Firefly algorithm. A numerical example and sensitivity analysis on the main parameters of the model are used to describe the importance and applicability of the developed model.

The findings showed that the Firefly algorithm performed better and identified more profit for the SC in each period. Also, the results of the sensitivity analysis using the IoT in a VCLSC showed that the profit of the virtual supply chain (VSC) is higher compared to not using IoT due to tracking defective parts and identifying reversible products. In proposed model, chain members can help improve chain operations by tracking raw materials and products, delivering products faster and with higher quality to customers, bringing a new level of SC efficiency to industries. As a result, VSCs can be controlled, programmed and optimized remotely over the Internet based on virtual objects rather than direct observation.

There are limited researches on designing and optimizing the VCLSC network. This study is one of the first studies that optimize the VSC networks considering minimization of virtual costs and maximization of profits. In most researches, the theory of VSC and its advantages have been described, while in this research, mathematical optimization and modeling of the VSC have been done, and it has been tried to apply SC virtualization using the IoT. Considering virtual costs in VSC optimization is another originality of this research. Also, considering the uncertainty in the SC brings the issue closer to the real world. In this study, virtualization costs including security, recall and energy consumption in SC optimization are considered.

This study aims to investigate the impact of job rotation on employee performance and explores the mediating role of human resources (HR) strategy and training effectiveness on this relationship, within the petrochemical industry, which represents a highly specialist and hazardous industrial context.

Data was collected through a questionnaire which was distributed among the experts working in an Iranian petrochemical organization. Previously validated scales were used to measure job rotation, employee performance, HR strategy and training effectiveness, and partial least squares structural equation modeling was used for hypothesis testing.

The research findings indicated that job rotation had a negative effect on employee performance, while training effectiveness and HR strategy positively mediated the relationship between job rotation and employee performance. This highlights the importance of ensuring effective training and a HR strategy to support job rotation of skilled and specialist employees.

Managers of employees in specialist and hazardous industries, such as petrochemical workers, interested in job rotation to support employee career development, should be mindful of potential negative implications on employee performance. To support and improve employee performance, job rotation should be considered alongside HR strategy and training.

Previous research has largely focused on the value of job rotation to develop managers’ organizational understanding and to reduce injury within blue-collar work, which has led to a paucity of research into job rotation within highly skilled and specialist industrial roles. It is highlighted within the literature that it remains unclear what supports effective job rotation. This study addresses this lacuna by investigating how job rotation affects employee performance in a highly skilled and specialized industry and how strategy and training effectiveness mediate this effect.

The majority of emerging adults in the United States spend time in cohabiting unions. Prior research has suggested that higher levels of sexual non-exclusivity may exist among those in cohabiting relationships compared to marital unions. Although these basic patterns have been explored in prior work, research examining the potential reasons why levels of sexual non-exclusivity differ by union status has been limited. Drawing on a relational perspective and using the fifth wave of data from the Toledo Adolescent Relationships Study (TARS), the present study found that higher levels of sexual non-exclusivity in cohabiting relationships were explained by intimate relationship characteristics and sexual histories rather than sociodemographic factors, partner heterogamy, or partner- and couple-level drug use. These findings highlighted that understanding the higher rates of sexually non-exclusive experiences in cohabiting relationships, compared to marital relationships, requires attention to specific dynamics of the intimate partnership and prior relational experiences of both partners. The study concluded that cohabitation has a unique place in emerging adults’ relationship landscape and may set the groundwork for future relationship functioning.

The purpose of this paper is to report on a scoping review of the advantages and challenges of extra care housing (ECH) provision in the UK for people living with dementia. Access to suitable housing is a fundamental right for people living with dementia and can enable people to live as well as possible (Twyford and Porteus, 2021). Understanding the advantages and disadvantages of different models of housing with care has been identified as a research priority by people living with dementia (Barrett et al., 2016) but “there is no current consensus on the best model of specialist housing for people with dementia” (Twyford and Porteus, 2021, p. 29).

This scoping review identifies the advantages and disadvantages of living in ECH for people with dementia. It is the preliminary stage of a study that seeks to develop knowledge about different models of ECH for people living with dementia (Atkinson et al., 2021).

Advantages include the promotion of independence, flexible staffing, safety and security, social inclusion, physical design and integrated service provision. Disadvantages include barriers to entry, tensions between independence and support, managing advanced dementia, resourcing flexible care, managing social exclusion, loneliness and stigma and a disabling environment.

The scoping review reinforces the need for further research into different models of ECH provision in the UK for people living with dementia. The review provides insight that is of benefit to all stakeholders involved in ECH and contributes to the development of evidence-based provision called for in the recent All Party Parliamentary Group inquiry (Twyford and Porteus, 2021).

This scoping review summarises the current position for people living with dementia in ECH.

Conflict and violence are the main drivers of globally escalating humanitarian needs. Local grassroots initiatives are pivotal in distributing humanitarian supplies in the acute response phase until more established humanitarian aid organizations can enter. Nevertheless, scant research exists regarding the role of grassroots associations in providing humanitarian assistance during a military conflict. The purpose of this paper is to understand the role of grassroots associations and identify important themes for effective operations.

This paper adopts a case-study approach of three Ukrainian grassroots associations that began operating in the immediate days of the full-scale invasion of Ukraine. The findings are based on analyzing primary sources, including interviews with Ukrainian volunteers, and are supported by secondary sources.

Grassroots associations have local contacts and a contextual understanding of population needs and can respond more rapidly and effectively than large intergovernmental agencies. Four critical themes regarding the operations of grassroots associations emerged: information management, inventory management, coordination and performance measurement. Grassroots humanitarian response operations during conflict are challenged by personal security risks, the unpredictability of unsolicited supplies, emerging volunteer roles, dynamic transportation routes and shifting demands.

Grassroots responses are central to humanitarian responses during the acute phase of a military conflict. By examining the operations of grassroots associations in the early months of the 2022 war in Ukraine, the authors provide a unique perspective on humanitarian logistics. Nonetheless, more inclusive models of humanitarian responses are needed to harness the capacities and resilience of grassroots operations in practice.

This paper aims to report the findings of a survey study exploring perceptions about cognitive impairment. These findings are relevant to public health campaigns and education programmes.

A survey exploring respondents’ views and knowledge about mild cognitive impairment (MCI) was circulated via UK networks. A total of 417 respondents completed the survey, including people living with cognitive impairment (n = 10), care partners (n = 23), older adults (n = 83), younger adults (n = 83), general health-care professionals (n = 96), dementia specialist health-care professionals (n = 48) and dementia specialists (n = 40).

Respondents were more confident in their knowledge about dementia than cognitive impairment but wanted more information about both conditions. Younger adults were uncertain about many aspects of MCI, and were the most likely to view MCI as a normal part of ageing. Diet (45.1%, n = 188) and personal behaviour (63.8%, n = 266) were the least endorsed possible causes of MCI, suggesting a lack of awareness of lifestyle choices as risk factors for MCI.

The results highlight the need to provide education and awareness raising about MCI to enable people to seek help in a timely manner and be able to make informed lifestyle choices that may reduce their risk of MCI and dementia. Implementing education about MCI and dementia in schools is a key target, as younger people were the most uncertain or misinformed about these topics. It is clear that further public health initiatives around MCI are both warranted and welcomed by the general public.

Meeting Centres (MCs) are a complex community-based psychosocial intervention to support people affected by dementia. The purpose of this paper is to describe the process of identifying the essential features of MCs from a UK perspective.

The essential features were examined within a concept analysis framework, which combines both static and evolutionary methods, enabling multiple stakeholder groups to be included in the process in an iterative manner.

Eleven essential features were developed, providing a conceptual model of the UK MCs. The underpinning rationale is sufficiently flexible to enable community-based development, while at the same time providing a robust platform upon which to build the evidence base.

While some features may be common to other types of community-based support, the combination of characteristics and the underpinning ethos differentiates MCs and enables each one to meet the needs of its own community.

With the goal of helping consumers bounce back from the financial challenges they faced as a result of the COVID-19 pandemic, many firms developed and announced consumer-targeted resiliency programs (e.g. Walgreens waived delivery fees, Associated Bank allowed deferred mortgage payments). However, there is a paucity of research examining the unique features of these programs, and whether firms' investors (the first external stakeholder group to provide them with feedback regarding their strategies) were receptive to these programs during a period of time in which firms themselves were suffering financially. Drawing on resilience theory and stakeholder theory, the present research incorporates an event study of consumer-targeted resiliency program announcements to understand their financial implications for firms, and to learn whether firms witnessed different financial effects as a result of firm- and program-specific factors.

This study referred to business news publications and newswire services to collect a comprehensive list of consumer-targeted resiliency programs announced by publicly traded U.S. firms during the pandemic. The resulting dataset consisted of 145 announcements made during the period of February–June 2020. An event study was conducted in order to precisely measure the main effect of consumer-targeted resiliency programs on firm value, as manifested through abnormal stock returns. Finally, a moderation analysis (regression) was conducted to uncover whether firm characteristics or specific features of firms' consumer-targeted resiliency programs lead certain firms to witness stronger financial effects than others.

The main effect of consumer-targeted resiliency programs on firm value was found to be positive – a 1.9% increase on average. The moderation analysis finds that non-financial firms were rewarded more positively than financial firms (e.g. banks and credit card companies). In addition, financial aid (i.e. allowing customers to defer their payments to a firm for its products/services, versus a reduction in the price of a product/service or offering it for free or giving cash back to customers) and temporal characteristics (i.e. an offer being framed as limited-time, vs being indefinite or for the foreseeable future) are not found to have a moderating effect.

This theory-driven empirical study uncovers practical implications for managers of firms interested in whether investing in corporate social responsibility during times of crisis is a wise allocation of resources. Any form of financial aid for consumers, regardless of temporal limitations, is received positively by investors.

Business model innovation (BMI) has been posited as essential for both new and existing digital business, as they commonly operate in competitive and fast-moving markets with limited entry barriers. However, it is highlighted within the literature that the understanding of how BMI contributes to business success and how new digital ventures develop competitive advantage is still unclear. This study aims to address this lacuna by exploring how young Chinese digital businesses develop and innovate their business models to survive in fast-moving and competitive markets.

This research adopted a multiple case study design, with qualitative data being collected from the founders of five Chinese digital businesses, to develop an understanding of the evolution of their business models and BMI from their inception.

The findings add support for the contention that BMI can play an important role and is beneficial in the success of such new digital ventures in highly competitive environments. The founders attribute their success to a willingness for continued BMI, an openness to new opportunities, developing customer relationships and continuous iteration.

This research addresses calls to further the authors’ understanding of how BMI contributes to business success and how new digital ventures develop competitive advantage by exploring the BMI of five highly successful digital businesses from their inception.
