Abstract

Purpose

Recently the advances in wireless communication technology and the popularity of portable computers have rendered mobile computing environments from which mobile users with battery‐operated palmtops can access the information via wireless channels, without space and time restriction. In mobile computing environments, mobile users cache the data items to use the bandwidth efficiently and improve the response time of mobile transactions. If the data items cached in mobile users are updated at the server, the server broadcasts an invalidation report for maintaining the cache consistency of mobile users. However, this method has an obstacle that does not guarantee the serializable execution of mobile transactions. The purpose of this paper is to propose the four types of reports for mobile transaction (FTR‐MT) method for ensuring the serializable execution of mobile transactions.

Design/methodology/approach

The paper describes the FTR‐MT method, which is composed of four types of algorithms, e.g. group report composition algorithm, immediate commit decision algorithm, cache consistency algorithm, and disconnection cache consistency algorithm. FTR‐MT method for improving the response time of mobile transactions makes a commit decision by using the four types of reports.

Findings

With the FTR‐MT method, mobile users can make a commit decision by using the four types of reports. The response time of mobile transactions can be reduced. Furthermore, the FTR‐MT method can improve the cache efficiency in the case that the disconnection of mobile users is longer than the broadcast interval of the window report.

Originality/value

This paper proposes a new method for guaranteeing the serializable execution of mobile transactions, called FTR‐MT, using four types of reports. Also, it can prevent the entire cache dropping, even though the disconnection of a mobile host is longer than the broadcast interval of a window report. Through the analytical model, this method is felt to be superior to other methods, in terms of the average response time and the commit rate of mobile transactions, and bandwidth usage.

Abstract

Purpose

In view of the influences of online videos on the cultural tourism industry, this study aims to explore the mechanisms triggered by watching online video behaviors of fans. This study examines how fans who have watched celebrities’ online videos become tourists who attend concerts held at destinations based on celebrity and destination endorsements.

Design/methodology/approach

This study builds for celebrity and destination endorsements on online videos by combining media richness and source model theory. This research adopts partial least squares structural equation modeling to analyze the mechanism triggered by online media.

Findings

Watching online media influences celebrity and destination endorsements, which, in turn, affects the concert experience and intention to return to the destination. Results reveal less intertwined relationships between celebrity and destination endorsements and the complex mechanisms between the two endorsements.

Originality/value

With the rise in popularity of online media, online content has become a major source of information in the tourism industry and a means of enjoying travel seamlessly. This study highlights not only the role of “watching online videos” as one of the richest media but also the role of live concerts in cultural tourism for understanding complex cultural tourism.

Abstract

Purpose

The purpose of this paper is to propose an automatic method to generate semantic annotations of football transfer in the news. The current automatic news integration systems on the Web are constantly faced with the challenge of diversity, heterogeneity of sources. The approaches for information representation and storage based on syntax have some certain limitations in news searching, sorting, organizing and linking it appropriately. The models of semantic representation are promising to be the key to solving these problems.

Design/methodology/approach

The approach of the author leverages Semantic Web technologies to improve the performance of detection of hidden annotations in the news. The paper proposes an automatic method to generate semantic annotations based on named entity recognition and rule-based information extraction. The authors have built a domain ontology and knowledge base integrated with the knowledge and information management (KIM) platform to implement the former task (named entity recognition). The semantic extraction rules are constructed based on defined language models and the developed ontology.

Findings

The proposed method is implemented as a part of the sport news semantic annotations-generating prototype BKAnnotation. This component is a part of the sport integration system based on Web Semantics BKSport. The semantic annotations generated are used for improving features of news searching – sorting – association. The experiments on the news data from SkySport (2014) channel showed positive results. The precisions achieved in both cases, with and without integration of the pronoun recognition method, are both over 80 per cent. In particular, the latter helps increase the recall value to around 10 per cent.

Originality/value

This is one of the initial proposals in automatic creation of semantic data about news, football news in particular and sport news in general. The combination of ontology, knowledge base and patterns of language model allows detection of not only entities with corresponding types but also semantic triples. At the same time, the authors propose a pronoun recognition method using extraction rules to improve the relation recognition process.

Abstract

Purpose

The purpose of this paper is to identify and deliberate the service development needs required for the improvement of service provision for incarcerated adults with autism spectrum disorder (ASD) in NSW, Australia.

Design/methodology/approach

Consultation groups were conducted to bring together n=5 key stakeholders from heath and correctional-based services in the prison system. A facilitated asynchronous e-mail-based discussion occurred amongst group members between consultation group meetings.

Findings

Two main themes were identified: detecting persons with ASD and providing appropriate care. Participants discussed current service gaps with regard to the identification of people with ASD at the point of contact with the prison service, and the difficulties associated with diagnosing prisoners with ASD. The need for effective alert systems to detect persons with ASD in custody was identified. The current absence of ASD-specific support services in prison was highlighted, and recommendations for improvement suggested.

Practical implications

Current health and correctional-based service provision failed to adequately support incarcerated adults with ASD. Improvements in prison-entry screening processes, alert systems and diagnostic practices are required. Multidisciplinary collaboration between prison-based and external service providers is required for the development of a model of care based on individualised case management to adequately support incarcerated adults with ASD in prison.

Originality/value

Given the lack of reported service provision for incarcerated adults with ASD internationally, other prison-based services are likely to experience similar service development needs and see the relevance of the recommendations made directly from the study findings.

Abstract

Purpose

The purpose of this paper is to describe the experience of a southern English young offenders institution in developing and implementing standards to improve awareness and care of prisoners with autistic spectrum disorders (ASD).

Design/methodology/approach

Some contextual factors driving the project are discussed, the multi-agency process involved in the development and implementation of the standards is described and recommendations are made regarding implementation of the standards in other settings.

Findings

It is expected that successful implementation of the standards will reduce the level of distress and difficulty experienced by people with ASD who find themselves in custody, it will also improve the prison’s ability to meet the needs of prisoners with ASD and thereby improve rehabilitation and reduce any adverse impact on everyday operational processes. Demonstrating success in meeting the standards will enable the prison to achieve accreditation by the National Autistic Society. In March 2015 the prisons minister encouraged all prisons to follow this approach and this will have practice and resource implications.

Originality/value

This paper describes a clear framework which prisons can use to work systematically towards achieving good practice in addressing the needs of prisoners with ASD. It will enable prisons to meet the duties imposed on them by the Autism Act, 2009 and the Equalities Act, 2010.

Abstract

The turbulent phase of COVID-19 has caused uncertainty as governments fail to develop coherent strategies for cutting emissions and are struggling to match the rhetoric of sustainable activities with actions (Barbier & Burgess, 2020; Cawthorn, Kennaugh, & Ferreira, 2021). In the recent past, firms have failed in their plans to decarbonise their key sectors such as the retail sector in the United Kingdom So far, retailers' commitment to achieving net zero emissions has been an important pledge but delivery is nowhere closer to their promises (Henriques, 2020). The firms' climate targets are not going to be met by magic as serious action is needed to fulfil the promises.

Fossil fuels have led to a drastic increase in carbon emissions in the world over the last decade. Firms championing cleaner energy and low carbon technologies are needed to cut emissions. Renewable energy sources such as wind energy can help reducing the dependency of fossil fuels (Boretti, 2020; Ebhota & Jen, 2020). Wind is an indirect form of solar energy which can provide environment-friendly option in uncertain times and can provide long-term sustainability of global economy. Solar energy technologies have the potential to decrease climate change through energy-related emissions (Li, Dai, & Cui, 2020). Increasing energy demand has initiated a focus on using hydrogen from water as a substitute for oil and fossil fuels (Boretti, 2020).

The first part of the chapter discusses theoretical perspectives of sustainable development and environmental performance with regards to three main issues: energy, water and carbon emissions, whereas the later part highlights the importance of solar technology as a low-polluted alternative to fossil fuels in the retail sector. Sustainable development of energy, water and environmental precautions such as reducing carbon emissions are of interest to wider branches of industries including retail, energy and water sector, governmental policymakers, researchers, educators and society. The purpose of this chapter is to increase the debate of the key issues of sustainable development regarding environment, energy and water in the modern times.

Abstract

We contend that the international strategy adopted by and the international experience of top executives in parent firms, as well as the embeddedness of foreign subsidiaries in host countries, moderate the impact of institutional distance between home and host countries on the divergence of isomorphic pressures experienced by foreign subsidiary managers. We further suggest that diverging isomorphic pressures are more likely to spur foreign subsidiary managers to deinstitutionalize organizational routines from parent firms when these managers possess knowledge‐based power, the subsidiary’s performance is declining, or social controls are lacking from the parent firm. Implications for research and practice are discussed.

Abstract

Purpose

Religion and spirituality (R/S) are recognized components of recovery-oriented mental health services. This study aims to present a clinically focused tool for assessing R/S interest among veterans with serious mental illness (SMI).

Design/methodology/approach

A questionnaire including 39 items was developed by experienced chaplains and mental health clinicians and administered to modest pilot sample of 110 participants in a recovery-oriented program at a medical center of the US Veterans Health Administration (VHA).

Findings

Altogether 40 (37%) participants said they would like R/S issues to be a greater part of their treatment (i.e. very or extremely). A screening tool to identify veterans for referral to R/S focused interventions was developed based on the selection of the five items most strongly loading on the strongest factor in a factor analysis.

Research limitations/implications

First, the identification of items for the survey was made on the basis of clinical experience with issues discussed by veterans in a VA recovery-oriented program and thus are based on clinician experience and their association with a stated desire for more R/S in their treatment. Since no gold-standard measure of “religion/spirituality” has been universally established and validated, this method, though imperfect, was accepted as practical and as having face validity. Furthermore, the sample size, while substantial, was limited and was not representative of the general population. Again, this was a pilot study of a unique effort to identify R/S issues of greatest relevance in a recovery program for people with SMI.

Practical implications

In this SMI sample, 36% of the participants said that they would like more R/S to be incorporated into their treatment. Factor analysis showed the desire for uplifting religious/spiritual community to be the predominant factor and formed the basis for a five-item screening tool that can be used to briefly identify services needs in this area of recovery.

Social implications

This screening tool can help incorporate religious and spiritual issues into mental health treatment, and area of importance that is often neglected. The results could help destigmatize this area of recovery practice for people with SMI.

Originality/value

This R/S survey of SMI adults suggests that over one-third of the participants in a pilot sample in a recovery-oriented program would like more R/S emphasis in their treatment. Factor analysis showed the desire for uplifting religious/spiritual community to be the predominant factor.
