Abstract

Purpose

The purpose of this paper is to suggest a formalism given by an equation suitable for simulating discrete systems with space-time variation in addition to other change variables. With such formalism, multidimensional dynamical models of discrete complex systems, such as the social systems and ecosystems, can be built.

Design/methodology/approach

This formalism is named as discrete multidimensional dynamic system (DMDS). The DMDS provides a way to consider the variation of the density of a state variable with regard to the variables of the change space as a function of multidimensional rates. Multidimensional rates describe this evolution as a consequence of the relation of each multidimensional-point with a given set of other points of the change space. This relation contains the accessibility domains (sets of space points with which each space point is related).

Findings

This equation is compared with both the reaction-diffusion equation written in its finite difference form and the cellular-automata model, demonstrating its compatibility with them and an increase in generality, widening the scope of application. The steps to construct models of systems with multidimensional variation based on the equation that defines the DMDS are specified and tested.

Research limitations/implications

Through the DMDS and a well-stated methodology, an application case is provided in order to describe the multidimensional demographic dynamics of an urban system. In this case, the numerical evolution of the population density by districts and cohorts is determined by the DMDS based on some hypothesis about functions of population diffusion between the different districts of the system.

Originality/value

The scope of application of the space-time dynamic system (STDS), given by the authors in a previous work, has been extended to discrete and multidimensional systems. STDS model produces better results than the reaction-diffusion model in validation.

Abstract

This paper documents the case of La Verde, a producer cooperative in Andalusia, Southern Spain, whose members grow and sell organic fruit and vegetables. Fieldwork data reveal a range of assessments and practices with respect to just price. Historical experiences of working as day laborers, with little access to cash or other resources informs the members’ radical political views on money, prices, and markets. These ideas modulate exchanges at the local level, and in their political networks. However, working their own land and selling a prized product allows them to generate good market returns from private shopkeepers in cities. The paper proposes that for a price to be considered just, criteria for commensuration, or equivalence between a price and the perceived value of an object must adhere, but adjudications about this vary according to the relationship between exchangers. Rather than an objective just price, the paper considers assessments and judgments about the relation between prices and justice to be contextually defined, contested, and negotiated.

Abstract

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Abstract

In this chapter, the author considers how Melbourne’s grindcore metal scene produces itself as coherent, authentic and masculine through the discursive positioning of Sydney’s scene as lacking, inauthentic and feminine and/or homosexual. The way Melbourne scene-members talk about Sydney in ethnographic interviews and online, indicates how Melbourne’s grindcore scene identity rests on a particular striving towards – and fantasy of – a bounded, comprehensible masculine identity anchored in Symbolic/linguistic signifiers of homophobia. Building on my previous research on Melbourne’s scene, the author utilises a Lacanian perspective to argue that the masculinist talk of Melbournians works as a response to the affective experience of enjoying grindcore music. Here, the author departs from my earlier work, where the author used Deleuzian/Massumian understandings of affect to suggest that affect works to construct community belonging in grindcore scenes (2014). Instead, the author uses Lacan’s approach to affect to suggest that Melbourne grindcore fans construct their identity via furiously producing a fantasy of Sydney fans as ‘Other’. They Symbolically construct Sydney as a ‘cultural wasteland’ populated by ‘poofter[s]’ (Melbourne Grind Syndicate, 2016) who are imagined, and positioned as, inauthentic due to their affective enthusiasm for grindcore. Here, affect works to exclude and Other grindcore fans rather than as a force for collectivity.

Abstract

Purpose

This paper reviews and assesses the aim, substance, and impact of Simon Susen’s book, “The Postmodern Turn” in the Social Sciences.

Methodology/approach

The review follows the structure of Susen’s book, by description and by evaluation.

Findings

Susen’s book encompasses a very large volume of literature of the self-defined “postmodern,” then concludes that the covered material has contributed little that is new to the social sciences.

Originality/value

The review has not been previously published, does not replicate any prior assessment known to the author.

Abstract

Purpose

The increased use and proven benefits of building information modelling (BIM) worldwide suggest that its implementation could be of great help in diminishing inefficient traditional practices in the Dominican Republic (DR) construction industry. However, there is no empirical work about the implementation of BIM in the country. This study aims to critically appraise and document the status of the implementation of BIM in the DR to raise awareness and understand how BIM can be successfully implemented in the country.

Design/methodology/approach

A qualitative approach was adopted in which data was collected through semi-structured interviews, with the participation of 53 professionals from 36 construction organisations. The data collected was analysed with the method of content analysis.

Findings

The results confirmed that the DR is a BIM infant country. There are low levels of BIM implementation. The reasons why BIM is not implemented are explored, and a significant interest in implementing BIM in the future was also reported. Drivers to implement BIM include BIM benefits, competitive advantage and pressure from external partners. Current BIM approaches are mainly single-disciplinary, principally in architecture, and the effectiveness and scope of implementation are highly affected by intra-organisational and inter-organisational barriers.

Originality/value

There is a lack of research about the implementation of BIM in the DR. This study bridges this research gap by collecting primary data from Dominican construction organisations and construction professionals to report findings related to BIM implementation.

Abstract

Virtual currency is a digital representation of value that is neither issued by a central bank or a public authority. Its reliability is based on advanced cryptographic methods which provide privacy and confidence to citizens. Virtual currency and its underlying technologies such as blockchain or smart contracts trigger transformation in many areas of the society’s functioning. The way in which social relations occur and economic transactions are managed are changing forever. As a result, cryptocurrencies constitute a good example of how specific technology may lead to substantial transformation of the world. Still, virtual currencies could benefit from the versatility of collaborative communication of social media and Internet to promote and develop new commerce and business initiatives as well as new forms of financial flow managements. The objective of this chapter is to examine the role played by virtual currencies in modern societies in order to describe potential uses and applications and their impact on politics and social behavior. As a result, recommendations are inferred to address the challenges and opportunities of these new technologies.

Abstract

Purpose

The purpose of this paper is to analyze the Brexit effect – pre-Brexit and post-Brexit referendum periods – on the co-movements between the British pound (GBP), the euro (EUR) and the yen (JPY) against the US dollar (USD).

Design/methodology/approach

To ascertain the asymmetric behavior of dynamic correlations, the authors use the dynamic conditional correlation (DCC) model, the asymmetric dynamic conditional correlation (A-DCC) model and the diagonal BEKK model assuming Gaussian and Student’s t distribution. Several dummy variables have been included in order to identify the main periods related to Brexit.

Findings

Findings show a negative impact of the pre-Brexit referendum period on the correlation between GBP and EUR, while there is no significant effect on GBP–JPY and EUR–JPY pairs. The loss of correlation in the GBP–EUR pairing has not recovered during the post-Brexit referendum period, which could be attributed to the uncertainty about the final impact of Brexit on British and Eurozone economies.

Practical implications

The loss of correlation in the GBP–EUR pair has important implications for individual investors, portfolio managers and traders with respect to hedging activities, international trading and investment strategies.

Originality/value

The results are the first to address how Brexit has impacted on the co-movements between exchange rates using different multivariate models that allow for correlations to change over time.

Abstract

This chapter reviews and synthesizes three major strands of recent research, alongside discipline-specific research design, from scholars of Language Issues in Comparative and International Education. The first strand is mixed methods research on the policy and practice of L1-based multilingual education programs, and their contribution to raising educational quality and addressing equity and inclusiveness worldwide. The second strand is qualitative, community-based research of educational programs aimed toward revitalization of minoritized, indigenous, and/or endangered languages. The third strand is empirical and theoretical research that seeks to document, contest, and reconceptualize the dynamics among dominant and non-dominant languages within and between international contexts. The authors explore points of synergy between studies, examine publication in the field from a meta-perspective, and suggest encouraging directions of future research, while highlighting the value of non-dominant languages as resources for education and life.
