PurposeWine tourism has stood out as a very recognized and valid tourism and marketing segment, growing worldwide and urging the complex needed advances on wine tourism practices performance. This paper aims to develop a new framework strictly applied to the global wine tourism system, taking into account emerging and future constructs and dimensions that precede and consequence it.Design/methodology/approachThe systematic mapping study (SMS) was adopted as the selected research methodological approach, both to analyze and to structure a broad research field concerning methods, designs and research, focuses on the papers published in reliable academic databases such as Emerald, ProQuest, Sage, Science Direct, Scopus, Wiley, Web of Science, Taylor and Francis and Wiley were properly selected and analyzed.FindingsThe following four dimensions were found to comprise the global framework of the wine tourism system: (1) support features (governance, public policies and economic investment; supply development; physical and capacity conditions; requirements of health safety; opinion makers and leaders: managers/stakeholders/players/marketers and benchmarking and value chain); (2) innovation ecosystem (profile of the new generations of wine tourists; virtual and augmented reality: digital and hybrid wine events; smart wine tourism companies; digital channels and platforms: blogs, websites, applications; wine tourism creative activities for all [from kids to seniors] and sustainable and ecologic wine tourism practices); (3) wine tourism experience dimensions (storytelling; involvement; winescape; attachment; emotions and sensory) and (4) behavioural intentions (satisfaction; loyalty; and WoM).Research limitations/implicationsThe framework still needs to be empirically applied in wine tourism settings to enrich tourists’ robustness in cross-cultural wine tourism experiences, covering a wider spread of abroad wine tourism destinations and products.Practical implicationsThis framework is a useful tool and becomes vital to their continued success, as a key reference of wine tourism management and marketing. As a wine tourist's visitation frequency plays a role in his/her travel motives, product and service quality of tour packages must be improved and monitored.Originality/valueThis is the first research study to demonstrate the combined use of the main domains forming the wine tourism system within a global perspective, covering of the most critical aspects.

The success of grid computing in open environments like the Internet is highly dependent on the adoption of mechanisms to detect failures and malicious sabotage attempts. It is also required to maintain a trust management system that permits one to distinguish the trustable from the non-trustable participants in a global computation. Without these mechanisms, users with data-critical applications will never rely on desktop grids, and will rather prefer to support higher costs to run their computations in closed and secure computing systems.This paper discusses the topics of sabotage-tolerance and trust management. After reviewing the state-of-the-art, we present two novel techniques: a mechanism for sabotage detection and a protocol for distributed trust management. The proposed techniques are targeted at the paradigm of volunteer-based computing commonly used on desktop grids.

Most business enterprises are small and medium-sized enterprises (SMEs), and many of them are without a human resource and recruitment department. Thus, one of the challenges that organizations currently face is to find a strategy to retain and attract talent. To overcome this difficulty, enterprises must invest in employer branding policies and be aware of the factors that differentiate them from others when attracting employees. This study aims to develop an employer branding model applicable to SMEs, to increase and enhance the attraction and retention of talents. An exploratory approach based on a quantitative perspective was adopted to develop an employer branding model applied to SMEs, with two major reference employer branding models and frameworks used as the main support. The model of employer branding was applied to SMEs regarding four dimensions, whereby essential questions are asked, namely (1) organizational culture (e.g., do employees have a job description aligned with the corporate culture?), (2) company strategy (e.g., what is the strategy if business volume decreases?), (3) company reputation (e.g., how do you perceive and treat negative feedback?), and (4) reward systems (e.g., do you feel that your employees are motivated intrinsically or extrinsically or both?), ordered by layers based on a logical sequence. The new proposed model is expected to serve as a useful strategic tool and as a basis for attracting, retaining and managing talent, specifically in the SMEs context. This new model provides a set of strategic and competitiveness benefits for SMEs, while contributing to making enterprises more profitable. The model also contributes to SMEs having a better image and reputation, enabling them to stand out from others in the war for talent.

Mobile Edge Computing enables the deployment of services, applications, content storage and processing in close proximity to mobile end users. This highly distributed computing environment can be used to provide ultra-low latency, precise positional awareness and agile applications, which could significantly improve user experience. In order to achieve this, it is necessary to consider next-generation paradigms such as Information-Centric Networking and Cloud Computing, integrated with the upcoming 5th Generation networking access. A cohesive end-to-end architecture is proposed, fully exploiting Information-Centric Networking together with the Mobile Follow-Me Cloud approach, for enhancing the migration of content-caches located at the edge of cloudified mobile networks. The chosen content-relocation algorithm attains content-availability improvements of up to 500% when a mobile user performs a request and compared against other existing solutions. The performed evaluation considers a realistic core-network, with functional and non-functional measurements, including the deployment of the entire system, computation and allocation/migration of resources. The achieved results reveal that the proposed architecture is beneficial not only from the users' perspective but also from the providers point-of-view, which may be able to optimize their resources and reach significant bandwidth savings.
