Abstract

Purpose

Major public cloud providers, such as AWS, Azure or Google, offer seamless experiences for infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). With the emergence of the public cloud's vast usage, administrators must be able to have a reliable method to provide the seamless experience that a public cloud offers on a smaller scale, such as a private cloud. When a smaller deployment or a private cloud is needed, OpenStack can meet the goals without increasing cost or sacrificing data control.

Design/methodology/approach

To demonstrate these enablement goals of resiliency and elasticity in IaaS and PaaS, the authors design a private distributed system cloud platform using OpenStack and its core services of Nova, Swift, Cinder, Neutron, Keystone, Horizon and Glance on a five-node deployment.

Findings

Through the demonstration of dynamically adding an IaaS node, pushing the deployment to its physical and logical limits, and eventually crashing the deployment, this paper shows how the PackStack utility facilitates the provisioning of an elastic and resilient OpenStack-based IaaS platform that can be used in production if the deployment is kept within designated boundaries.

Originality/value

The authors adopt the multinode-capable PackStack utility in favor of an all-in-one OpenStack build for a true demonstration of resiliency, elasticity and scalability in a small-scale IaaS. An all-in-one deployment is generally used for proof-of-concept deployments and is not easily scaled in production across multiple nodes. The authors demonstrate that combining PackStack with the multi-node design is suitable for smaller-scale production IaaS and PaaS deployments.

Abstract

Purpose

The purpose of this paper is to use an evaluation of a micro-place-based hot-spot policing implementation to highlight the potential issues raised by data quality standards in the recording and measurement of crime data and police officer movements.

Design/methodology/approach

The study focusses on an area of London (UK) which used a predictive algorithm to designate micro-place patrol zones for each police shift over a two-month period. Police officer movements are measured using GPS data from officer-worn radios. Descriptive statistics regarding the crime data commonly used to evaluate this type of implementation are presented, and simple analyses are presented to examine the effects of officer patrol duration (dosage) on crime in micro-place hot-spots.

Findings

The results suggest that patrols of 10-20 minutes in a given police shift have a significant impact on reducing crime; however, patrols of less than about 10 minutes and more than about 20 minutes are ineffective at deterring crime.

Research limitations/implications

Due to the sparseness of officer GPS data, their paths have to be interpolated which could introduce error to the estimated patrol dosages. Similarly, errors and uncertainty in recorded crime data could have substantial impact on the designation of micro-place interventions and evaluations of their effectiveness.

Originality/value

This study is one of the first to use officer GPS data to estimate patrol dosage and places particular emphasis on the issue of data quality when evaluating micro-place interventions.

Abstract

Purpose

The purpose of this paper is to investigate the role of smartphones among young people in everyday life, focusing on the activity of online search. This paper addresses the following research questions: What framings of the smartphone can be identified in the way that young people use, and describe, smartphones? What is the role of online search within these framings? By elucidating framings of the smartphone, this paper also seeks to discuss why and how smartphone use becomes contested in various contexts and situations.

Design/methodology/approach

The material has been produced through ethnographic fieldwork. Focus groups and observations have been carried out with teenagers, age 13–16 years, in three schools in Sweden. In total, 39 pupils participated in the focus groups. Interviews, classroom observations and go-alongs have also been performed.

Findings

In this study, three framings of the smartphone are identified: the entertainment framing, the easy-access framing and the challenging co-presence framing. The framings highlight the way that both the smartphone and online search is viewed, and carried out, in various situations. The smartphone is primarily viewed as a tool for entertainment, by adults and young people alike, yet the findings illustrate that the smartphone is used for more activates than what is immediately apparent.

Research limitations/implications

This study contributes to the field interested in bridging the gap between in-school teachings of information literacies and out-of-school activities by showing how online search happens in various situations. Also, to the field concerned with people’s use of general web search engines in everyday life.

Originality/value

This paper explores the relation between online search and smartphones, a topic which has not been in focus in previous research. The topics of online search and smartphone use have primarily been researched separately but are here researched in conjunction.

Abstract

Purpose

In Ghana, the adoption and application of green building concepts and technologies have not been fully explored. The study aimed to look into the key barriers and how they affect this.

Design/methodology/approach

Purposive and snowball sampling techniques were used to select a total of 292 construction industry stakeholders in Ghana who provided information via a questionnaire survey used for the data collection. Exploratory factor analysis and Partial least squares structural equation modelling (PLS-SEM) were used for computing the data analyses.

Findings

According to the study findings, the top five most critical barriers to the uptake of green building concepts and technologies (GBCs and Ts) in Ghana are: lack of government incentives/supports for implementing green building technologies (GBTs), lack of knowledge and awareness of GBTs and their benefits, lack of GBTs databases and information, Lack of green building (GB) expertise/skilled labour and Higher costs of GBTs. Principal Component Factor Analysis was used to further analyse the data, which allowed for the reduction of the 27 (27) factors to just four (4) underlying critical barriers: (1) government and knowledge-associated barriers, (2) technical barriers, (3) cost and finance barriers and (4) stakeholders’ attitude barriers. PLS-SEM techniques were used to analyse this collection of barriers, and the results showed that stakeholders’ attitude-associated barriers and cost and finance-related barriers have a significant negative influence on the uptake of GBCs and Ts in Ghana. This study’s findings have provided empirical evidence of the critical barriers to the uptake of GBCs and Ts from all stakeholders. Stakeholders desirous of implementing GBCs and Ts would work against the negative influences on the uptake of GBCs and TS.

Originality/value

Although there has been an abundance of research to examine the critical barriers to GB, however, the uniqueness of this study is nested in modelling the influence of the barriers on the adoption of GBCs and Ts using the PLS-SEM path modelling.

Abstract

Purpose

The present research conducts a thorough review of published literature relevant to earnings management (EM) practices in family firms (FFs), utilizing the Scopus database, intending to identify potential directions for future research.

Design/methodology/approach

Through a systematic review, this study focuses on identifying and summarizing trends in publications over the years, the journal outlets, geographical contexts, research methodologies, the temporal evolution of theories and the specific constructs under investigation.

Findings

Earlier empirical studies suggest that corporate governance enhances integrity and transparency in FFs, thereby reducing EM practices. Contrarily, compliance with International Financial Reporting Standards (IFRS) seems to offer managers more opportunities for convenient EM rather than restricting such practices. Notably, corporate social responsibility (CSR) practices do not appear to mitigate EM practices consistently. The literature, however, reveals inclusive results and areas requiring deeper exploration for more definitive results. For instance, certain corporate governance mechanisms, such as family-specific social and cultural business characteristics, subjective measures of family businesses, behavioral approaches to family owners' decision-making and directors' personal, psychological and social factors, remain largely untested. Additionally, there is a notable research gap concerning the relationship between IFRS, capital structure and EM.

Originality/value

This study’s contributions lie in its comprehensive literature review, identification of research trends and gaps, and its potential to guide future research endeavors in the domain of EM practices in FFs.

Abstract

Purpose

Sex tourism is well documented in the literature, but what about porn tourism? Whether it is a Ping Pong show in Phuket or the Banana show in Amsterdam, porn and tourism have an encounter and gaze no different from the Mona Lisa in the Louvre or magnificent views of New Zealand’s Southern Alps. The paper aims to discuss these issues.

Design/methodology/approach

This paper explores the intersections of tourism, porn and the future as a conceptual framework.

Findings

Four intersections are derived from the conceptual framework. Intersection 1, the Future of Tourism, portrays the evolution of tourism and explores its technological future. Interaction 2, Porn in Tourism, distinguishes between soft- and hard-core porn tourism. Intersection 3, Portraying Porn as a Future Dimension, delves into futurism, science fiction and fantasy. The fourth intersection, the Future Gaze, conveys the thrust of the paper by exploring how technological advancement blends with authenticity and reality. Thus the porn tourist seeks both the visual and the visceral pleasures of desire. The paper concludes with four future gazes of porn tourism, The Allure of Porn, The Porn Bubble, Porn as Liminal Experience and Hardcore.

Originality/value

The originality of this paper is that this is the first paper to systematically examine porn tourism beyond sex tourism overlaying with a futures dimension. Porn tourists actively seek to experience both visual and visceral pleasures. Tourism and pornography both begin with the gaze. The gaze is an integral component of futures thinking. Technology is changing us, making us smarter, driving our thirst for liminal experiences. Like the transition from silent movies to talking pictures the porn tourism experience of the future is likely to involve more of the bodily senses.

Abstract

Purpose

As the global presence of Chinese firms grows, increasing numbers of Chinese managers are working abroad as expatriates. However, little attention has been paid to such Chinese expatriate managers and their leadership challenges in an inter-cultural context, especially across a large cultural distance. To fill the gap in the literature concerning the leadership challenges for expatriate managers in an inter-cultural context, the purpose of this paper is to elucidate the leadership styles of Chinese expatriate managers from the perspectives of three traditional Chinese philosophies (i.e. Confucianism, Taoism, and Legalism) in the inter-cultural context of the Netherlands.

Design/methodology/approach

The data for this qualitative study were collected via semi-structured, open-ended, narrative interviews with 30 Chinese expatriate managers in the Netherlands.

Findings

The results clearly show that the leadership style of Chinese expatriate managers is deeply rooted in the three traditional Chinese philosophies of Confucianism, Taoism, and Legalism, even in an inter-cultural context. Specifically, the study reveals two salient aspects of how Chinese expatriate managers frame and interact with a foreign cultural context from the perspectives of traditional Chinese philosophies. First, the Chinese expatriate managers reported an initial cultural shock related to frictions between the foreign cultural context and Confucianism or Taoism, but less so in the case of Legalism. Second, the Chinese expatriate managers also reported that their interactions with the Dutch culture are best described as a balance between partial conflict and partial complementarity (thus, a duality). In this sense, the leadership style of Chinese expatriate managers is influenced jointly by the three traditional Chinese philosophies and certain elements of the foreign cultural context. This is consistent with the Chinese perspective of yin-yang balancing.

Originality/value

This study is among the first to offer a more nuanced and highly contextualized understanding of leadership in the unique case of expatriate managers from an emerging market (e.g. China) in an advanced economy (e.g. the Netherlands). The authors call for more research to apply the unique perspective of yin-yang balancing in an inter-cultural context. The authors posit that this approach represents the most salient implication of this study. For practical implications, the authors argue that expatriate leaders should carefully manage the interplay between their deep-rooted home-country philosophies and their salient host-country culture. Reflecting on traditional philosophies in another culture can facilitate inter-cultural leadership training for Chinese expatriates.

Abstract

Purpose

This study aims to identify the attitudes of Chinese residents towards tourists and tourism development. Based on periods of observation, temporary residency and several visits for more than a decade, and supplemented by data collected from 478 residents, the study examines to what extent the rural villagers identify the tourism induced changes as being an outcome of official Chinese policies. The villages, Xidi, Hongcun and Nanping, are three heritage villages in Anhui Province and represent appropriate case studies for such an examination due to their differing histories of tourism administrative procedures. Findings contribute to scholarly knowledge by putting pro-poor tourism and community participation under scrutiny in Chinese context. A change of residents’ perceptions towards tourism could potentially be consequential for tourists’ experience and the sustainability of tourism development, particularly in emerging rural destinations.

Abstract

Purpose

This study aims to consider active vision in low-visibility environments to reveal the factors of optical properties which affect visibility and to explore a method of obtaining different depths of fields by multimode imaging.Bad weather affects the driver’s visual range tremendously and thus has a serious impact on transport safety.

Design/methodology/approach

A new mechanism and a core algorithm for obtaining an excellent large field-depth image which can be used to aid safe driving is designed and implemented. In this mechanism, atmospheric extinction principle and field expansion system are researched as the basis, followed by image registration and fusion algorithm for the Infrared Extended Depth of Field (IR-EDOF) sensor.

Findings

The experimental results show that the idea we propose can work well to expand the field depth in a low-visibility road environment as a new aided safety-driving sensor.

Originality/value

The paper presents a new kind of active optical extension, as well as enhanced driving aids, which is an effective solution to the problem of weakening of visual ability. It is a practical engineering sensor scheme for safety driving in low-visibility road environments.
