Abstract

Purpose

The purpose of this paper is to introduce a novel cross (+) type yoke with hybrid electromagnets and new reluctance modeling to precisely calculate attraction force is given.

Design/methodology/approach

The comparison of attraction force and torque analyses between the proposed formulation and the existing formulation in the literature is comparatively presented. For the correctness of the force and torque values calculated in the model created, the system was created in ANSYS Maxwell and its accuracy was proved by making analyses. The maglev carrier system is inherently unstable from the point of view of control engineering. For that, it needs an active controller to eliminate this instability. For the levitation of the carrier system, it is necessary to design a controller in three axes (z, α and β). I-PD controller was designed for the air gap control of the carrier system in three axes and the controller parameters were determined by the canonical method.

Findings

While the new formulation proposed in the modeling of the carrier system has a maximum error of 1.03%, the existing formula in the literature has an error of 16.83% in the levitation distance point.

Originality/value

A novel cross-type hybrid carrier system has been proposed in the literature. With the double integral used in modeling the system, it takes a long time to solve symbolically, and it is difficult to simulate dynamic behavior in control validation. To solve this problem, attraction force and inclination torque values are easily characterized by new formulation and besides the simulations are conducted easily. The experimental setup was manufactured and assembled, and the carrier system was successfully levitated, and reference tracking was performed without overshoot.

Abstract

Purpose

This study aims to investigate perceptions about interactive travel websites. The researchers hypothesize that engaging content, the quality of information and source credibility have a significant effect on the consumers’ utilitarian motivations to continue using them in the future.

Design/methodology/approach

A structured survey questionnaire was used to gather data from 1,287 online users, who were members of two popular social media groups. The methodology relied on a partial least squares approach to analyze the causal relationships within an extended information adoption model (IAM).

Findings

The findings reveal that the research participants perceive the utility of interactive travel websites and are willing to continue using them, particularly the responsive ones. The research participants suggest that these sites are easy to use, capture their attention and offer them useful information on various tourism services. The results also indicate that they appreciate their source credibility (in terms of their trustworthiness and expertise of their curators) as well as their quality content.

Research limitations/implications

This study integrates key measures from the IAM with a perceived interactivity construct, to better understand the individuals’ acceptance and use of interactive websites.

Practical implications

This research implies that service businesses ought to have engaging websites that respond to consumer queries in a timely manner. Hence, they should offer a seamless experience to their visitors to encourage loyal behaviors and revisit intentions to their online domains.

Originality/value

To the best of the authors’ knowledge, there are no other studies that incorporated an interactive engagement construct with key constructs from IAM and from the technology acceptance model (TAM). This contribution underlines the importance of measuring the individuals’ perceptions about the engagement capabilities of interactive media when investigating information and/or technology adoption.

Abstract

Purpose

Customers are increasingly using mobile applications (apps) to compare prices of travel and hospitality services and to purchase their itineraries, tours and stays. This study aims to explore key factors affecting the individuals’ perceptions on the usefulness of travel apps and sheds light on the causal paths predicting the individuals’ dispositions to use them.

Design/methodology/approach

Quantitative data was gathered from 1,320 research participants, who were members of popular social media groups. They were analyzed through a composite-based partial least squares approach.

Findings

The results confirm that information quality, source credibility and the functionality of travel apps are significantly affecting the individuals’ perceptions about their usefulness as well as their intentions to continue using them in future. They also indicate that there are highly significant indirect effects within the information technology adoption model.

Research limitations/implications

This study integrates the information quality and source credibility factors from the information adoption model (IAM) with a functionality construct that was drawn from electronic service quality. This study examines their effects on the technology acceptance model (TAM)’s perceived usefulness and behavioral intentions.

Practical implications

This research implies that there is scope for the travel service providers to enhance the quality and functionality of their mobile apps to improve their consumers’ perceptions about the utilitarian value of these ubiquitous technologies.

Originality/value

This contribution raises awareness on the importance of incorporating a functionality construct in addition to IAM and/or TAM “usability” factors to better understand the individuals’ dispositions to avail themselves of online content and/or to adopt interactive innovations. In this case, it implies that certain functionality features of travel apps, including their responsiveness and technical capabilities, can trigger users to increase their engagement with these mobile technologies on a habitual basis.

研究目的

客户越来越多地使用移动应用程序 (apps) 来比较旅行和酒店服务的价格, 并购买他们的行程、旅游和住宿。 本研究探讨了影响个人对旅行应用程序有用性看法的关键因素, 并阐明了预测个人使用这些应用程序的倾向的因果路径。

研究设计/方法/途径

本研究从 1,320 名流行社交媒体团体的成员作为研究参与者收集了定量数据。 通过基于复合材料的偏最小二乘法 (PLS) 方法对它们进行了分析。

研究发现

结果证实, 信息质量、来源可信度和旅游应用程序的功能显着影响个人对其有用性的看法以及他们未来继续使用它们的意图。 它们还表明, 信息技术采用模型 (ITAM) 中存在非常显着的间接影响。

实际意义

这项研究表明, 旅游服务提供商可以提高其移动应用程序的质量和功能, 以提高消费者对这些无处不在的技术的实用价值的看法。

理论意义

本研究将来自信息采用模型 (IAM) 的信息质量和来源可信度因素与从电子服务质量 (eSERVQUAL) 中提取的功能结构相结合。 本研究检查了它们对技术接受模型 (TAM) 的感知有用性和行为意图的影响。

研究原创性

这一贡献提高了人们对在 IAM 和/或 TAM“可用性”因素之外加入功能结构的重要性的认识, 以更好地了解个人利用在线内容和/或采用交互式创新的倾向。 在这种情况下, 这意味着旅游应用程序的某些功能特性(包括响应能力和技术能力)可以触发用户习惯性地增加对这些移动技术的参与。

Abstract

Along with accounting scandals in the past, academics, researchers, and legislators have focused on fraud. The purpose of this study is to examine postgraduate and doctoral studies, articles, and books about forensic accounting and fraud audit published between the years 2008 and 2018 in Turkey. For this purpose, a total of 96 studies have been examined and 35 of these are master’s theses, 10 of them are PhD theses, 45 of them are articles, and six of them are books. These studies were presented in tables as classified. The studies examined in our research are summarized as year they were published, the author, and the scope of the topic and in terms of results. The conclusions of this study can be summarized as follows: (a) the majority of thesis published about forensic accounting and fraud audit are in 2011 and following years. In addition, most of the theses are focused on forensic accounting review rather than fraud audit. (b) Results in the articles reviewed are in the same direction with theses. (c) There are very few books about fraud audit and forensic accounting. One of them is related to fraud audit, while the rest of them are related to forensic accounting and forensic accounting profession. We suggest extending the scope of the study and making to other countries.

Abstract

Political science and public administration have seen significant transformations as a result of digitalization. The literature depicts the transformation brought about by digitalization at various stages. In the literature, these periods are termed as Public Administration 1.0 (Cameralism), Public Administration 2.0 (Weberian Bureaucracy), Public Administration 3.0 (New Public Administration), Public Administration 4.0 (Digital Public Administration) and Public Administration 5.0 (Super Smart Society). Not only has digitalization contributed to a more effective, efficient and accountable service understanding, but it has also contributed to the dissolution of the rigid understanding between voters and politicians. However, digitalization has brought both problems and benefits to the field. By creating a fast world, unconfirmed information reaches a greater number of people, bringing negative situations with it. Aside from the societal benefits of digitalization, the methods to be considered will also be discussed in this study.

Abstract

Purpose

The purpose of this paper is to identify the strain of oyster mushroom (OM) Pleurotus sapidus cultivated in a local (commercial) farm, and to generate a total quality index (TQI) on the strain using different modified atmosphere packaging (MAP) gas mixtures.

Design/methodology/approach

A phylogenetic tree was constructed using the MEGA software to identify the specific strain of P. sapidus grown in a local farm. The effects of MAP on fresh fruiting bodies of the identified strain were determined under three conditions: high carbon dioxide packaging (HCP: 20 per cent CO2, 15 per cent O2), low carbon dioxide packaging (LCP: 2 per cent CO2, 30 per cent O2) and high nitrogen packaging (HNP: 85 per cent N2, 15 per cent O2). All samples were stored at 4 oC for up to ten days, and subjected to total phenolic content (TPC), colour retention (CR) and sensory analysis. Quality parameters such as chewiness and odour were used to obtain the TQI.

Findings

From the phylogenetic analysis, a new strain (P. sapidus strain QDR) with 99 per cent similarity to P. sapidus was identified. Among the three MAP treatments, HCP recorded the highest TPC (2.85 mg GAE/g) and CR (60.36) after ten days, although only its CR was significantly different (p<0.05) from the control. Feedback from 30 sensory panellists indicated that both HCP and LCP were generally more effective in retaining the colour–odour of OM. The optimum TQI for HCP was obtained based on the observed parameters, which is useful for the large-scale packaging of OM.

Originality/value

Scientific evidence has revealed that packaging trend for commercially grown OM affects consumer’s acceptance.

Abstract

Purpose

This study aims to examine the current state of literature on structural equation modeling (SEM) studies in “cloud computing” domain with respect to study domains of research studies, theories and frameworks they use and SEM models they design.

Design/methodology/approach

Systematic literature review (SLR) protocol is followed. In total, 96 cloud computing studies from 2009 to June 2018 that used SEM obtained from four databases are selected, and relevant data are extracted to answer the research questions.

Findings

A trend of increasing SEM usage over years in cloud studies is observed, where technology adoption studies are found to be more common than the use studies. Articles appear under four main domains, namely, business, personal use, education and health care. Technology acceptance model (TAM) is found to be the most commonly used theory. Adoption, intention to use and actual usage are the most common selections for dependent variables in SEM models, whereas security and privacy concerns, costs, ease of use, risks and usefulness are the most common selections for causal factors.

Originality/value

Previous cloud computing SLR studies did not focus on statistical analysis method used in primary studies. This review will display the current state of SEM studies in cloud domain for all future academics and practical professionals.

Abstract

Purpose

A large number of organisations are moving towards adopting Industry 4.0 (I4.0), and simultaneously, the emphasis on attaining sustainability development goals is also increasing. Hence, it is imperative to understand the interplay between I4.0 and sustainability. However, the literature addressing the same is still in infancy. Accordingly, the purpose of this study is to fill this gap in the literature by exploring the potential sustainability impacts of I4.0 on the organisations and society in terms of sustainability risks.

Design/methodology/approach

To gain an understanding of sustainability aspects in the I4.0 context, relevant literature is gathered using Scopus and Web-of-Science database. An in-depth review of 51 research papers is performed to determine the sustainability risks associated with I4.0.

Findings

From the study, a total of 16 sustainability risks are identified, and I4.0 sustainability risk taxonomy is developed. The proposed taxonomy extends the sustainability implications of I4.0 beyond the triple bottom line umbrella and includes the organisational perspective as well. Furthermore, the study provides future research avenues to scholars by positing five potential research questions under different risk management stages.

Research limitations/implications

The study provides an understanding of sustainability risks associated with the adoption of I4.0. The findings will help practitioners streamline their production and operation processes by finding out possible solution to the sustainability risks of their smart factories in advance. The present research will act as a stepping stone towards I4.0 sustainability. The proposed research questions will assist the future researchers in extending the field of I4.0.

Originality/value

To the best of the authors’ knowledge, this is one of the first studies to address the topic of sustainability risks in the context of I4.0.
