The explosive growth of Internet applications and content, during the last decade, has revealed an increasing need for information filtering and recommendation. Most research in the area of recommendation systems has focused on designing and implementing efficient algorithms that provide accurate recommendations. However, the selection of appropriate recommendation content and the presentation of information are equally important in creating successful recommender applications. This paper addresses issues related to the presentation of recommendations in the movies domain. The current work reviews previous research approaches and popular recommender systems, and focuses on user persuasion and satisfaction. In our experiments, we compare different presentation methods in terms of recommendations' organization in a list (i.e. top N-items list and structured overview) and recommendation modality (i.e. simple text, combination of text and image, and combination of text and video). The most efficient presentation methods, regarding user persuasion and satisfaction, proved to be the ''structured overview'' and the ''text and video'' interfaces, while a strong positive correlation was also found between user satisfaction and persuasion in all experimental conditions.

Purpose The purpose of this paper is to identify the factors that managers have to take into consideration when they implement the strategic information systems planning (SISP) process to develop information systems (IS) in the logistics sector. Design/methodology/approach Data were collected using questionnaires to IS executives in Greek small- and medium-sized enterprises (SMEs) of the logistics sector. Factor analysis is performed on the detailed items of the SISP process constructs. Findings The results of this paper indicate that IS executives do not focus on defining goals, which will be used to improve the operations of the supply chain for the IS development. Both IS executives and managers from the logistics department of each organization should participate in the process of information technology (IT) strategy formulation and implementation. Executives from the logistics department of each organization should be aware of implementing environmental and organizational analysis with greater meticulousness, to identify IT opportunities and apply IT strategy with greater agility rather than now. Practical implications A strategic planning process for IS development in the logistics sector is required to achieve the consistently IS planning objectives. This is an important challenge for executives in SMEs who do not concentrate on implementing a strategic planning process for IS development. Originality/value This paper examines the factors that influence the strategic development of IS in the logistics sector and improve the effectiveness of decision-making regarding the supply chain’s operation.

Technology acceptance theories predict user intentions to use services tailored for organisational needs. However, in this paper, we postulate that the aforementioned theories do not apply when investigating intentions towards the use of mobile data services (MDS), as the latter encompasses supplementary characteristics, such as fun and enjoyment, which are not taken into account under available models of user acceptance. The incorporation of the affective dimension is proposed by reintroducing the Triandis theory of human behaviour to the MDS domain. A web-based survey (N ¼ 219) was conducted to investigate our research hypotheses and validate our model of MDS usage intention. Results showed that the MDS usage intention can be predicted by cognitive and affective factors under the lens of social influences. Additionally, the main antecedents of MDS actual use are perceived usefulness, perceived value and intention to use MDS.

Mobile business research has arguably grown to become one of the most topical and complex eBusiness research areas in recent years. As a result, researchers face a plethora of interdisciplinary research challenges. Understanding the range of these challenges and confronting them requires coordinated research efforts, backed up by a holistic guiding approach. This paper aims at contributing to the future of mobile business research by proposing a roadmap to systematise and guide future research efforts, providing a methodical outlook to open research issues across all dimensions defining mobile business and prioritises future research in each dimension in the form of short-, medium-, and long-term research challenges
