Abstract

Purpose

In response to the increasing number of open‐source software (OSS) project initiatives and the increasing demand of OSS products as alternative solutions by industries, it is important for particular stakeholders such as the project host/supporter project‐leading teams, and prospective customers to determine whether a project initiative is likely to be sustainable and is worth supporting. This paper aims to propose a concept of “health” indicators and an evaluation process that can help to get a status overview of OSS projects in a timely fashion and predict project survivability based on the project data available on web repositories.

Design/methodology/approach

For initial empirical evaluation of the concept, the indicators are applied to well‐known web‐based OSS projects (Apache Tomcat and Apache HTTP Server) and the results are compared with challenged projects (Apache Xindice and Apache Slide). The results are discussed with OSS experts to investigate the external validity of the indicators.

Findings

From a software project management point of view, a typical web‐based OSS project can be viewed as a web‐engineering process, since most OSS projects exploit the benefits of a web platform and enable the project community to collaborate using web‐based project tools and repositories such as mailing lists, bug trackers, and versioning systems (CVS/SVN) to deliver web systems and applications. These repositories can provide rich collections of process data, and artifacts which can be analyzed to better understand the project status.

Originality/value

The paper provides information of value about open‐source solutions.

Abstract

Purpose

This paper aims to present a collaborative mashup platform for dynamic integration of heterogeneous data sources. The platform encourages sharing and connects data publishers, integrators, developers and end users.

Design/methodology/approach

This approach is based on a visual programming paradigm and follows three fundamental principles: openness, connectedness and reusability. The platform is based on semantic Web technologies and the concept of linked widgets, i.e. semantic modules that allow users to access, integrate and visualize data in a creative and collaborative manner.

Findings

The platform can effectively tackle data integration challenges by allowing users to explore relevant data sources for different contexts, tackling the data heterogeneity problem and facilitating automatic data integration, easing data integration via simple operations and fostering reusability of data processing tasks.

Research limitations/implications

This research has focused exclusively on conceptual and technical aspects so far; a comprehensive user study, extensive performance and scalability testing is left for future work.

Originality/value

A key contribution of this paper is the concept of distributed mashups. These ad hoc data integration applications allow users to perform data processing tasks in a collaborative and distributed manner simultaneously on multiple devices. This approach requires no server infrastructure to upload data, but rather allows each user to keep control over their data and expose only relevant subsets. Distributed mashups can run persistently in the background and are hence ideal for real-time data monitoring or data streaming use cases. Furthermore, we introduce automatic mashup composition as an innovative approach based on an explicit semantic widget model.

Abstract

Travel counseling and recommender systems on the Internet have not yet become smart enough to fulfill the elementary functions a fastidious consumer may expect. The EU‐funded project named DieToRecs (http://dietorecs.itc.it/) aims at improving recommender system functionality by incorporating relevant findings from tourist behavior research. The computational intelligence needed to optimize the user‐system encounter greatly depends on how far the user has advanced in his travel decision process. This report elaborates the levels of counseling intelligence, explores the basic marketing paradigm of matching the products/services desired and offered, and ponders on the consequences for devising a recommender or counseling system capable of learning.

Abstract

Purpose

This study aims to investigate the effect of virtual reality experience quality on destination visit intention and virtual reality travel intention through the technology acceptance model (TAM).

Design/methodology/approach

Quantitative data gathered from questionnaires applied to 198 people after undertaking an imaginary three-dimensional (3D) destination experience were analyzed with PLS-SEM.

Findings

Virtual reality experience quality influences perceptions and intentions. The perceived ease of use affects perceived usefulness, perceived usefulness effects attitude and destination visit intention, while perceived risk affects only virtual reality travel intention. Attitude affects both intentions.

Research limitations/implications

The main limitation of the study relates to the quality of the experience offered, which is limited to the technical capacity of the virtual reality glasses used. Virtual reality can be used as a new economic offering and create a realistic destination experience. Virtual reality experience quality is an important determinant of intention in physical and imaginary travels, in shaping perceptions and minimizing travel risks. The explanatory power of the model can be increased by adding the perceived risk variable to TAM. The study has brought new perspectives, new insights and suggestions for developing tourism.

Originality/value

In the study, a 3D imaginary destination with its mise-en-scène and story, which includes more than one destination type, was designed. This study contributes to the literature by analyzing real and virtual visit intentions, combining the fields of the experience economy, risk perception and TAM.

研究目的

本研究通过应用技术接受模型, 探讨虚拟现实体验质量对目的地参访意愿和虚拟现实旅游意愿的影响。旨在识别这些变量之间存在的关系, 并解释这些关系的因果链接。

研究方法

本研究从198名参与虚拟三维目的地体验后填写的问卷中获得定量数据并通过PLS-SEM方法进行分析。

研究发现

虚拟现实体验的质量影响用户的感知和意愿。虚拟现实旅游意愿仅受感知风险的影响。感知易用性影响感知有用性。意愿受态度影响, 但感知有用性不影响虚拟现实旅游。

研究局限性/意义

本研究的主要局限性与提供的体验质量有关, 该质量受到虚拟现实眼镜技术能力的限制。虚拟现实可以作为一种新的经济提供方式进行开发。通过将感知风险变量添加到技术接受模型中, 可以增加模型的解释力。本研究为旅游业的发展提供了新的视角、见解和建议, 并解释了虚拟现实提供的真实目的地体。

研究创新

为了研究的目的, 本研究设计了一个虚拟的三维目的地, 包含多个目的地类型。该目的地有自己的布景和故事情节。本研究通过分析真实和虚拟参访意愿的领域, 将体验经济、风险感知和技术接受模型领域相结合, 为文献做出了贡献。

Abstract

Purpose

This study aims to examine the effectiveness of branding through franchising and hotel membership affiliations in Europe, where the chain penetration rate is still relatively low, albeit growing slowly, and where hotels are limited by historical preservation codes and building restrictions.

Design/methodology/approach

Although branding through affiliations has been a successful strategy in North America for decades, little is known of this strategy in Europe, where the fragmented hospitality industry comprises small and medium‐sized independent enterprises which are being subjected to increasing competitive pressure from large global chains. This exploratory study, using a purposive sample, examines the factors that European independent hotels consider before committing to a third‐party brand and whether they perceive their decision to have improved their overall performance.

Findings

It is revealed that these hoteliers perceive that they had significantly improved their overall market position situation without losing a large part of their uniqueness, independence and management control. Notwithstanding, some of the hoteliers were not satisfied with every aspect of their brand selection and it was concluded that the degree of success would be highly contingent on careful selection of the appropriate kind of branding tool option for each situation.

Practical implications

The main issues have been identified for hoteliers to consider when selecting a brand affiliation as well as the key components for the branding companies to include in their offers. Recommendations are provided for both.

Originality/value

Decision‐making criteria are provided for hoteliers in the form of a checklist to use including benefits and risks and other considerations, as well as a checklist of key success factors of leading hotel branding companies.

Abstract

Purpose

The purpose of this paper is to design a framework for asset data management in power companies. The authors consider asset data management from a strategic perspective, linking operational-level data with corporate strategy and taking into account the organizational context and stakeholder expectations.

Design/methodology/approach

The authors conducted a multiple case study based on a literature review and three series of in-depth interviews with experts from three Russian electric power companies.

Findings

The main challenge in asset data management for electric power companies is the increasing amount and complexity of asset data, which is frequently incomplete or inaccurately collected, hard to translate to managerial language, focused primarily on the operational level. Such fragmented approach negatively affects strategic decision-making. The proposed framework introduces a holistic approach, provides context and accountability for decision-making and attributes data flows, roles and responsibilities to different management levels.

Research limitations/implications

The limitations of our study lie in the exploratory nature of case study research and limited generalization of the observed cases. However, the authors used multiple sources of evidence to ensure validity and generalization of the results. This article is a first step toward further understanding of the issues of transformation in power companies and other asset intensive businesses.

Originality/value

The novelty of the framework lies in the scope, focus and detailed treatment of asset data management in electric power companies.
