Abstract

This paper reviews the real‐time enterprise from a technology point of view, with a strong focus on the challenges of building globally scalable technology. We analyze the different aspects of the real‐time enterprise and the link between the real‐time functionality and event driven systems. We then review the major bottlenecks in achieving scalability and robustness for event‐driven systems when they need to support global enterprise systems. At a conceptual level the real‐time enterprise is extremely promising but neither research nor product groups have the technologies to operate at a global scale in a manner that will allow the real‐time enterprise to become a reality, unless a number of significant hurdles are removed. This paper examines the impact of the concept of the real‐time enterprise on research agenda of academia as well as product groups, and lays out an agenda for achieving scalability and reliability goals.

Abstract

Purpose

This column aims to examine the issue of modular library technology infrastructure, and how it can help libraries to offer more flexible services to patrons.

Design/methodology/approach

This column is exploratory, and looks at the pros and cons of various technology approaches to digital library services.

Findings

In order to remain flexible with regard to the evolving needs of patrons, libraries should seriously consider a technology model which would allow the digital library to offer more responsive services to patrons. It is suggested that a deeper look at service‐oriented architecture (SOA) design principles as opposed to the standard model of large monolithic systems be examined and adopted.

Originality/value

This column offers alternatives in the area of digital library services, and focuses primarily on the possibilities rendered by service‐oriented architectures and robust web services.

Abstract

Purpose

This paper tries to locate the sectorial bubbles and examines the possibility for investors making extra profit from these bubbles in the Indian stock market.

Design/methodology/approach

The authors use two main indicators: (1) asset centrality and (2) relative value. Asset centrality signals crowded trading, which is associated with the formation of a bubble. Relative value separates the crowded trading during the bubble run-up from the sell-off. The authors observe whether these measures can detect the cycle of bubbles in each sector of the Indian stock market for the period 2004–2019.

Findings

The authors show the sectors going through the inflationary phase delivers much better performance than the index, whereas the sectors in their deflationary phase perform quite worse than the index. This provides attractive opportunities to investors, especially the institutional investors, and fund managers of the Indian market.

Originality/value

To the best of our knowledge, there is no study that looks into the idea of locating a sectoral bubble in the Indian financial stock market using the concept of centrality score and relative score. This work helps to locate a bubble and identify its phases successfully. Traders can enter a bubble in their inflationary period gain profit and exit the trade before the sell-off period begins.

Abstract

Purpose

This study aims to scrutinize time-varying return and volatility interlinkages among major cryptocurrencies, NFT tokens and DeFi assets between 1 July 2018 and 19 February 2023 and determine optimal portfolio allocations and hedging effectiveness under different portfolio construction techniques.

Design/methodology/approach

This work examines time-varying return and volatility interlinkages among major cryptocurrencies, NFT tokens, and DeFi assets between 1 July 2018 and 19 February 2023. To this end, the time-varying parameter-vector autoregression (TVP-VAR)-based connectedness methodology of Antonakakis et al. (2020) This approach is an extended version of the Diebold–Yilmaz (DY) method (Diebold and Yılmaz, 2014) and has advantages over the original DY. First, unlike the DY, it is free of the selection of a particular window size. Second, it has robustness for the outliers. Furthermore, following Broadstock et al. (2022), the author estimates time-varying optimal portfolio weights and hedging effectiveness under different portfolio construction scenarios.

Findings

This study's results indicate the following results: (1) The overall connectedness indices prominently capture well-known financial/geopolitical distress incidents; (2) the leading cryptocurrencies (ETH, BTC and BNB) are the largest transmitter of return shocks, while LINK and BTC are the largest transmitters/recipients of volatility shocks; (3) cryptocurrencies, NFTs and DeFi form distinct cluster groups in terms of return and volatility connectedness; (4) the connectedness networks estimated around the 2022 cryptocurrency crash and the FTX's filing for the bankruptcy are characterized by the strongest return and volatility interlinkages; (5) optimal portfolio strategies computed by different portfolio construction techniques display similar motifs and have sustained growth paths except for some short-lived drop backs.

Research limitations/implications

This study's findings imply several policy suggestions for investors, stakeholders and policymakers. First, the study's time-based dynamic interlinkages can help market participants in their optimal portfolio decisions. In particular, the persistent net receiving roles of the DeFi assets and the NFTs throughout the episode, especially around the financial/geopolitical turmoil, underpin their safe haven potentials (Umar et al., 2022a, b). Finally, since the total connectedness indices (TCIs) are prone to significantly increase around financial/geopolitical burst times, these tools can be valuable for policy makers to monitor risk.

Originality/value

The contribution of knowledge is at least threefold. First, the author focuses on the dynamic time interlinkages among major cryptocurrencies, NFTs and DeFi assets in July 2018 and February 2023 considering the prominent recent financial/geopolitical incidents. Second, the author estimates network topologies of dynamic connectedness around financial/geopolitical bursts and compared them in terms of interlinkages. Finally, the author calculates the time-varying optimal portfolio allocations and hedging effectiveness under different portfolio construction techniques.

Abstract

Learning outcomes

After reading and discussing the case, the participant would be able to: comprehend business expansion strategies and challenges of an entrepreneur dealing with handicraft and artefacts, digital marketing, entrepreneurship and marketing strategy; understand how a comprehensive digital marketing plan for the business is developed; discuss the pros and cons of digital marketing.

Case overview/synopsis

The handloom and handicraft industry has been the backbone of India’s rural economy for decades. It is one of the largest employment generators after agriculture, providing livelihood to country’s rural and urban population. The protagonist in the case had a strong inclination towards various art and craft forms, and her passion led her to start her venture – Guthali, wherein she sourced various handicrafts and handlooms from local artisans and after adding value to the fabric or art form through painting, block printing, etc., marketed it to the customers. However, the marketing was full of challenges, with brands like Fab India, enjoying high awareness and customer base. This case highlights the challenges faced by the protagonist to market Indian handicrafts and handloom in the urban market. The readers of the case would be able to learn about various stages involved in developing digital marketing strategies.

Complexity academic level

This case is suitable for postgraduate courses in digital marketing and entrepreneurship to understand the entrepreneurial challenges and come up with digital marketing solutions. This case is equally suitable for management development programmes on how digital marketing can help entrepreneurs grow their businesses.

Abstract

During its 230 year prison history, the United States has advocated various – and sometimes conflicting – purposes for incarceration. Each justification has rested on the tenets of some prevailing theory of human behavior (Akers & Sellers, 2008; Jones, 2008), which attempts to answer two recurring themes: why do some people commit crimes while others do not, and how should the criminal justice system, including the correctional system, respond to such behavior (Siegel, 2003; Winfree & Abadisky, 2010; Vito, Maahs, & Holmes, 2011). This chapter offers an overview of the general tenets of what is considered morally imperative when determining “right” from “wrong”; the four key criminological perspectives of crime, as well as the ontological assumptions, either explicit or implicit, within each hypothesis. Next, the authors discuss how these assumptions dictate society's response to crime and, more specifically, the type of punishment, rehabilitative efforts, or educational opportunities offered to those who violate society's laws (Bohn & Vogel, 2011). The chapter concludes with a discussion of the types of educational programs and therapies that have demonstrated the most promise at reducing crime and recidivism, as well as suggestions for improving current correctional practices.

Abstract

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

Abstract

Purpose

Using Andersen’s (1968) behavioral model of health services use as a guiding conceptual framework, this study examined how receipt of family-centered care relates to the perceived family challenges for families of children with autism spectrum disorder (ASD).

Design

Data from the 2009–2010 National Survey of Children with Special Health Care Needs (NS-CSHCN) were analyzed for 812 parents of children with ASD.

Findings

Multiple regression analyses provided substantive statistical evidence that a child’s race, the adequacy of a family’s insurance, and the stability of child’s health care needs significantly contributed to predicting his or her receipt of family-centered care. Further results suggested a relationship between receipt of family-centered care and the perception of challenge for these families; families receiving family-centered care perceive fewer challenges and feel less unmet need for child health services.

Value

Family-centered professionals provide critical voices in the development of policies and programs geared toward improving the health outcomes of children with ASD and their families.
