The transition from large to small working age cohorts and perpetually increasing longevity presents major challenges to pension systems around the world. In this context, the Danish system has been highlighted as particularly adequate and sustainable, although often developed more as element in macro-economic and fiscal policies than pension visions and certainly enabled and bolstered through other policies, such as fixed exchange rates, debt reduction, wage restraint, employment maximation and tax reform. The combined effect of six distinctive pension policy features places Danish pensions in the super-league of national systems: (1) a generous minimum pension providing all residents with basic old age security; (2) progressive redistribution resulting from the integration of public and private pension benefits; (3) high occupational pension coverage, with sizable contributions offering immediate membership, vesting and full portability of rights; (4) the tax regime, where investment return taxation substantially reduces the fiscal pressure from tax-exempting gross income in the build-up period and deferral of income tax until benefits are paid out, secures a revenue windfall at the height of ageing; (5) the linking of pensionable ages to life expectancy, which aims to lower pension costs, increases labour supply, growth and tax revenue and (6) the regime for third pillar schemes preventing their use in tax planning. Although the Danish pension experience has its obvious peculiarities, lessons for other governments can be found in the public‒private benefit integration, the tax regime, the life expectancy indexing of pensionable ages and the use of pensions in economic policies.

The chapter deals with a service-learning course based in the School of Journalism and Media Studies at Rhodes University in South Africa. It provides a backdrop for the case study, describing the context in which the course is based and kind of intervention that it aims to make into this context. It then maps out the theoretical framework that informs the course, explaining how this is informed by the available spectrum of approaches to service-learning. It demonstrates how the course draws on the concept of a ‘communicative ecology’, to provide itself with a language in which to reflect on the social significance of communication. The chapter then reviews the first cycle of the course which took place in 2019, drawing on insights from participants (teachers, students and community partners). It deals, firstly, with the participants’ engagement with the concept of service-learning. Secondly, it describes their experience of service-learning as a communicative process. Finally, it describes their evaluation of this process as an intervention into the local communicative ecology. It is demonstrated that service-learning enables the school to respond strategically to the need for innovative communicative practices both in their immediate environment and within the broader South African context.

This case study documents the move to emergency virtual learning at the University of Johannesburg. Prefacing promoting social justice and care, the authors explain how key challenges unique to a university in a developing world context were considered. The findings highlight the importance of agility, adaptability and the role of Ubuntu (i.e. values of compassion, solidarity and sharing) in higher education institutional leadership in a crisis. Furthermore, the authors highlight the need to address how structural inequality and poverty impact the pace of technological infusion in higher education in the Global South.

Blockchain, in general, diversifies supply chain management in record-keeping and maintains authenticity. In addition, traditional issues and challenges like overflow and information overload press down mysteriously whenever the blockchain steering wheel of the supply chain turns. Factually, the miracle and twists in supply chain resilience have not been incorporated under systematic review homogeneously. As a result, this study reviews the potential impact of blockchain on logistics and supply chain (LSC) efficiency. The methodology of this study provides a subjective assessment of the utility of blockchain-based LSC performance.

On the other hand, the review reveals new insights on its current acceptance and applications, with a particular emphasis on the Limit Redundancy Mechanism and Core Information-based Direct Comparison. Prospectively, the identified facts under the research paradigm and extensive literature survey will subsidize the practices of blockchain technology and possible areas of extension in supply chain resilience in luminous fashion in the future. After all, this study materializes new solid magnitudes, adaptability, and a realistic overview of blockchain-based LSC movements.

Motivated by research linking job autonomy and job creativity with psychological well-being, this study examines how these work characteristics influence well-being among people with and without physical disabilities, utilizing both a categorical and continuous measure of disability.

Data were drawn from two waves of a community study in Miami-Dade County, Florida, of 1,473 respondents. Structural equation modeling was used to assess whether job autonomy and job creativity mediate the associations between the indicators of physical disability considered and depressive symptoms and whether these associations varied by gender.

Controlling for the effects of the sociodemographic control variables, both job autonomy and job creativity significantly influence the association between physical disability and depressive symptoms regardless of the measure of disability used. The effects of job autonomy were significantly greater for women than men in the context of greater functional limitation.

The findings highlight the need to further consider the work characteristics of employed people with disabilities. They also demonstrate that the conceptualization and measurement of physical disability has important research implications.

This paper investigates the impact of blockchain technology on the Bricks and Mortar (B&M) grocery sector from a technological and functional perspective.

The research adopted an exploratory research design and the data comprises 17 semi-structured interviews with personnel at the top grocery retail chains in the United States, for example, Wal-Mart, Tesco, Stop and Shop and Meijer. Additionally, two major US-based blockchain service providers are included – SumatoSoft and Accubits.

Blockchain technology affects the business processes of B&M grocery retail by offering payment via tokens, secure payments and contracts between stakeholders, an end-to-end solution in the supply chain and secure management of the stock. However, this process is hampered by a number of challenges such as integrity and security concerns, difficulty in adapting sound logistics, lack of adequate skills and resistance to change by store managers and employees. This can be addressed by imparting education/training and creating awareness about the benefits of blockchain and generating industry-wide collaboration in which regulations can work.

The research has benefits for B&M grocery stores, governments and the wider society. For example, the findings of this study will help B&M grocery retailers to confront the competition by online retailers such as Amazon, AliExpress or eBay and promote the development of a systematic collaboration to achieve the changes they need.

The study is original and innovative in that no research to date has focused on how blockchain can help the B&M grocery sector and address its challenges.

This chapter critically discusses the many positive aspects that are ascribed to gazelle firms by exploring the external effects and dark sides of high firm growth. On the background of the more general debate on purpose versus profit as a firm’s mission, the chapter theoretically elaborates on the dichotomy between quantitative and qualitative growth of gazelles. This is followed by a case-based illustration and exploration as to how quantitative and qualitative growth interrelates in gazelles and what are impediments for high growth that is purpose driven. The chapter closes with a discussion of the Janus-faced nature of gazelles and how their corporate citizenship can be enhanced.

The purpose of this paper is to assess the application of graph coloring and domination to solve the airline-scheduling problem. Graph coloring and domination in graphs have plenty of applications in computer, communication, biological, social, air traffic flow network and airline scheduling.

The process of merging the concept of graph node coloring and domination is called the dominator coloring or the χ_d coloring of a graph, which is defined as a proper coloring of nodes in which each node of the graph dominates all nodes of at least one-color class.

The smallest number of colors used in dominator coloring of a graph is called the dominator coloring number of the graph. The dominator coloring of line graph, central graph, middle graph and total graph of some generalized Petersen graph P_(n ,1) is obtained and the relation between them is established.

The dominator coloring number of certain graph is obtained and the association between the dominator coloring number and domination number of it is established in this paper.

The purpose of this paper is to study current practices in adopting blockchain technology amongst export companies in West Sweden and to capture their CEOs’ knowledge of and attitudes towards blockchains.

Factors enabling or hindering the adoption of blockchains were identified from a comprehensive literature review and a survey of 72 chief executive officers (CEOs) of export-oriented firms in West Sweden, all with turnovers exceeding €2m, regarding their knowledge of and attitudes towards blockchains.

Blockchain technology is not currently perceived to provide benefits that would outweigh the costs of introducing it into West Sweden’s export firms. Nevertheless, the findings suggest that such technology, though currently too immature to meet today’s industrial requirements, could experience more widespread use if certain key factors (i.e. lower cost, traceability, improved security or trustworthiness and new blockchain-enabled business models) are prioritised.

Answered by 72 CEOs, the survey achieved a response rate of 6%, meaning that the findings are only exploratory. Even so, they offer new insights into CEOs’ attitudes towards blockchain technology.

The CEOs reported comparatively limited knowledge of and experience with implementing blockchains, the lack of which has hampered their large-scale implementation in multi-actor supply chains.

Negative sentiment amongst CEOs towards blockchain technology may lower on-the-job satisfaction amongst tech personnel aspiring to develop and implement blockchain applications in their firms.

Knowledge of and attitudes towards blockchain technology amongst top-level managers, as well as about factors enabling or hindering its adoption, guide managers in crafting strategies for implementing blockchains in their organisations and maximising the benefits therein. Unlike past studies focussing on technological aspects or views of experts and middle-management, the study was designed to capture the views of CEOs.

This chapter attempts to clarify the underlying mechanisms of the relationship between socioeconomic status and health outcomes. Former studies of this relationship have largely focused on the materialist predictors of health outcomes, examining variables such as income, access to healthcare, or quality of housing. The current study, by contrast, looks at individuals’ behaviors and attitudes, particularly in relation to physicians, and their impact on the quality of care patients receive. Using data from a sample of 64 hemodialysis patients in a middle-class suburb of Long Island, I examined the effect of comfort and ease with doctors and willingness to engage them on patient compliance. The findings suggest that patients who are more comfortable asking their doctors how they feel, and those that push for more information in general, tend to be more compliant, and therefore enjoy better and more successful patient outcomes.
