Switching Behaviour in Smart Phone Messaging Services : It’s a Question of Context, Content, and Features of the Service
2021
This paper studies switching behaviour in smart phone messaging services. This study aims to add knowledge about the factors affecting switching behaviour in smart phone messaging services. The empirical study is qualitative, and the data was collected with interviews using the laddering method. This study was carried out to find out the reasons behind customer decisions when choosing between smart phone messaging services. Using the Push-Pull Mooring framework, the findings of this study indicate that the switching decision regarding smart phone messaging service is influenced by three factors: the context of the message, the content of the message, and the features of the service.
A global service level guarantee in NGN networks
2010
In this paper, we propose an end-to-end service level negotiation protocol which enables a global service offer covering quality of service (QoS) and security while taking into account user's mobility in this offer. This protocol provides all the domains involved in the transport of a various offered services with a negotiation capability to achieve an agreement on a service level. This paper shows also results of measurements evaluating the performances of the considered negotiation protocol and security impact on QoS.
Healthcare access of immigrants: An integrated ecological framework
2019
Access to healthcare impacts in health, and for its importance it has been conceptualized by different theoretical models. Theories tackling social barriers have been established too. Nevertheless, a lack of theorization about healthcare access of immigrants exists, and there is no theory able to integrate all the scientific literature on this and its impact on the health of immigrants. In order to study the factors relating to the access of immigrants and to guide the development and evaluation of public health interventions, an integrative approach is needed. In this regard, from an ecological perspective healthcare access of immigrants would be shaped by interrelated factors in different…
PMG-pro: A model-driven method for the development of service-based applications in a heterogenous services environment
2010
This paper presents PMG-pro (present, model, generate and provide), a development method of service-based applications. With PMG-pro, the composition of heterogeneous pre-made services is done at model levels and thereby different executable software systems for different target platforms can be generated automatically. To illustrate the method, we present a case study of developing a service-based application in a smart home environment.
Transformations in Lifelong Guidance Provision
2012
In this chapter, the transformations taking place at the different levels of guidance provision are analyzed. The aim was to provide a tool to examine the interface between multisectoral guidance practice and policy development. On the basis of earlier research on regional guidance networks, a model is introduced in which schools, social, health, and public employment services can jointly design, implement, and evaluate guidance services. The model for Networked Guidance Service Provision (NEGSEP) focuses separately on the developmental needs of guidance services visible to clients, both with regard to service delivery and strategic dimensions. Along this line, a framework for networked gui…
Improvement of a Service Level Negotiation Protocol using Formal Verification
2013
International audience; The goal of the pervasive connectivity is to enable mobile users to be permanently connected to the Internet. Mobile users are often connected to wireless networks and consuming services that require quality of service guarantees. Accessing services using wireless technologies may make the service delivery vulnerable to security attacks because of the open medium of these technologies. In this context, we need to guarantee both quality of service and security for mobile users communications. In this paper, we present a protocol for service level negotiation which covers both quality of service and security and assigns a profile to each user in order to optimize and a…
Absorptive capacity and its impact on innovation and performance: findings from SEM and fsQCA
2018
Innovation can provide sustainable competitive advantages to service companies that consider the absorption of external knowledge a key strategic issue. Using the four dimensions of absorptive capacity, this study examined the impact of absorptive capacity on innovation in service delivery processes and explored how this innovation influences business performance. Structural equation modeling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA) were applied to a sample of 134 companies drawn from the Colombian tourism sector. The results of the SEM indicate that innovation in service delivery processes is positively influenced by two of the four dimensions of absorptive capacity…
Integrating multiple stressors in aquaculture to build the blue growth in a changing sea
2017
Fisheries currently represent the main source of animal protein intake worldwide, although catches of most commercial species are at or beyond maximum sustainable yields. Increasing production would require an excess of exploitation levels and aquaculture is expected to become crucial in sustaining a growing seafood demand. Nonetheless, many threats are expected to affect aquaculture and the increased production must evolve in a way that minimizes environmental and socio-economic impacts. The claimed sustainable development of human activities at sea (blue growth and economy) seeks for new joint analyses and solutions at (trans-)national systemic level should be planned and applied. To meet…
Assessment of the ecological status of transitional waters in Sicily (Italy): first characterisation and classification according to a multiparametri…
2010
A 1-year cycle of observations was performed in four Sicilian transitional water systems (Oliveri-Tindari, Cape Peloro, Vendicari and Marsala) to characterise their ecological status. A panel of variables among which trophic and microbial (enzyme activities, abundance of hetetrophic bacteria and of bacterial pollution indicators) parameters, were selected. Particulate organic carbon (POC) and nitrogen (PON) and chlorophyll-. a (Chl-. a) contents defined the trophic state, while microbial hydrolysis rates and abundance gave insights on microbial community efficiency in organic matter transformation and on allochthonous inputs. To classify the trophic state of examined waters, the synthetic t…
PROSPETTIVE E CRITICITÀ SUL RUOLO DEL BENTHOS MEDITERRANEO NELLA DIRETTIVA SULLA MARINE STRATEGY
2013
In Europe, the Marine Strategy Framework Directive (MSFD) and the Water Framework Directive (WFD) are the main regulations for the protection of water bodies. The translation of their principles into valid and practical approaches is the main challenge for the scientific community. An additional and even more severe problem is related to the MSFD application in the Mediterranean area. The aim of the present contribution is to picture the present situation in Italy, as far as the benthic communities in the MSFD are concerned, pinpoint some conceptual and practical critical points, and possibly suggest some new tools useful for the definition of Good Ecological Status (GES).
