Abstract

Purpose

This study aims to develop an interdisciplinary political theory of data justice by connecting three major political theories of the public good with empirical studies about the functions of big data and offering normative principles for restricting and guiding the state’s data practices from a public good perspective.

Design/methodology/approach

Drawing on three major political theories of the public good – the market failure approach, the basic rights approach and the democratic approach – and critical data studies, this study synthesizes existing studies on the promises and perils of big data for public good purposes. The outcome is a conceptual paper that maps philosophical discussions about the conditions under which the state has a legitimate right to collect and use big data for public goods purposes.

Findings

This study argues that market failure, basic rights protection and deepening democracy can be normative grounds for justifying the state’s right to data collection and utilization, from the perspective of political theories of the public good. The state’s data practices, however, should be guided by three political principles, namely, the principle of transparency and accountability; the principle of fairness; and the principle of democratic legitimacy. The paper draws on empirical studies and practical examples to explicate these principles.

Originality/value

Bringing together normative political theory and critical data studies, this study contributes to a more philosophically rigorous understanding of how and why big data should be used for public good purposes while discussing the normative boundaries of such data practices.

Abstract

Purpose

The literature has demonstrated that lump-sum (LS) outperforms dollar-cost averaging (DCA) in uptrend markets while DCA outperforms LS only when the asset price is mean-reverted or downtrend. To bridge the gap in the literature, this study aims to use both Sharpe ratio (SR) and economic performance measure (EPM) to compare the performance of DCA and LS under both accumulative and disaccumulative approaches when the asset price is simulated to be uptrend.

Design/methodology/approach

This study uses both disaccumulative and accumulative approaches to compare DCA with LS and uses both SR and EPM to evaluate their performance when the asset price is simulated to be uptrend. Instead of using the annualized returns that are commonly used by other DCA studies, we compute the holding-period returns in the comparison in this paper.

Findings

The simulation shows that no matter which approach is used, DCA outperforms LS in nearly all the cases in the less uptrend markets while DCA still performs better than LS in many cases of the uptrend markets, especially when the market is more volatile and investment horizon is long, regardless which approach the authors used. The authors also find more evidence supporting DCA over LS by using EPM, which is more suitable in the analysis because the returns generated by DCA are positive skewed and flat-tailed that are ignored when SR is used.

Research limitations/implications

The authors conclude that DCA is a better trading strategy than LS for investment even in the uptrend market, especially on high risky assets.

Practical implications

Investors could consider choosing DCA instead of LS as their trading strategy, especially when they prefer long term investment and investing in high-risk assets.

Social implications

Fund managers could consider recommending DCA to their customers, especially when they prefer long term investment and investing in high-risk assets.

Originality/value

This is the own study and, as far as the authors know, this is the first study in the literature uses both SR and EPM to compare the performance of DCA and LS under both accumulative and disaccumulative approaches when the asset price is simulated to be uptrend.

Abstract

Purpose

Since the launch of the Mainland and Hong Kong Closer Economic Partnership Arrangement (CEPA) in 2003, Hong Kong cinema is believed to have confronted drastic changes. Hong Kong cinema is described to be dying, lacking creative space and losing local distinctiveness. A decade later, the rise of Hong Kong – China coproduction cinema under CEPA has been normalized and changed the once pessimism in the industry. The purpose of this paper is to demonstrate how Hong Kong cinema adjusted its production and creation in the first 10 years of CEPA.

Design/methodology/approach

Beginning with a review of the overall development, three paradigmatic cases are examined for reflecting upon what the major industrial and commercial concerns on the Hong Kong – China coproduction model are, and how such a coproduction model is not developed as smooth as what the Hong Kong filmmakers expected.

Findings

Collectively, this paper singles out the difficulties in operation and the limit of transnationality that occur in the Chinese context for the development of Hong Kong cinema under the Hong Kong – China coproduction model.

Originality/value

This is the author’s research in his five-year study of Hong Kong cinema and it contributes a lot to the field of cinema studies with relevant industrial and policy concern.

Abstract

Purpose

The conceptualization of flexibility in organizations historically emerged from three views which relate to economic, to organizational and to manufacturing perspectives. Despite the growing number of publications about supply chain flexibility in the area of supply chain management, there is a lack of consensus on how to define and to conceptualize supply chain flexibility from a management point of view. The purpose of this paper is to present a comprehensive overview of the literature on the supply chain flexibility perspective and contributes to our understanding of the current state of research and its future development.

Design/methodology/approach

The research methodology used is the systematic literature review. In total 92 articles were selected from databases of well-known journal publishers in the field of economics, business studies and management sciences as well as grey literature to cover the topic of supply chain flexibility.

Findings

A limited number of studies in the field of supply chain flexibility apply theories and define the term supply chain flexibility. Instead they focus on a particular part or dimension of the supply chain. Based on the analysis, a distinction is made between flexibility in the supply chain and supply chain flexibility. Based on the function and characteristics of the supply chain, the authors selected 30 flexibility dimensions that cover supply chain flexibility by concentrating on the different business areas involved.

Research limitations/implications

The results support researchers and practitioners by identifying relevant trends and gaps in the field of supply chain flexibility.

Originality/value

The authors review the dimensions and aspects of supply chain flexibility that are currently taken into account in the literature. In this way, the authors provide an overarching perspective on the flexibility literature relating to supply chains.

Abstract

Purpose

The purpose of this paper is to address an important question which centres on investigating how do manufacturing businesses perceive and understand the concepts of agility and flexibility in their supply chains (SCs).

Design/methodology/approach

A case study approach was utilised and data were gathered from semi-structured interviews with ten organisations in the Australian manufacturing sector. Data analysis was conducted using analytic techniques based on, for example, pattern matching and cross-case synthesis.

Findings

Findings confirmed that there is some ambiguity concerning the understanding of the terms agile and flexible, both within and between organisations. The implications are that there is often little consistency in the way the terms are operationalised and then applied. In this regard, and to inform future research, the paper offers empirically grounded definitions for SC agility and flexibility. Moreover, four propositions are developed and discussed which shed light on the dynamics of agility and flexibility in the SC.

Originality/value

This is one of the first empirical studies to address some of the apparent inconsistencies between organisational applications of agility and flexibility, and their impact on SC operations.
