Copyright @ 2013 Elsevier B.V.This study aimed to identify factors that influence user attitudes towards mobile recommender systems and to examine how these factors interact with cultural values to affect attitudes towards this technology. Based on the theory of reasoned action, belief factors for mobile recommender systems are identified in three dimensions: functional, contextual, and social. Hypotheses explaining different impacts of cultural values on the factors affecting attitudes were also proposed. The research model was tested based on data collected in China, South Korea, and the United Kingdom. Findings indicate that functional and social factors have significant impacts on user attitudes towards mobile recommender systems. The relationships between belief factors and attitudes are moderated by two cultural values: collectivism and uncertainty avoidance. The theoretical and practical implications of applying theory of reasoned action and innovation diffusion theory to explain the adoption of new technologies in societies with different cultures are also discussed.National Research Foundation

Critical review of the e-loyalty literature: a purchase-centred framework
Over the last few years, the concept of online loyalty has been examined extensively in the literature, and it remains a topic of constant inquiry for both academics and marketing managers. The tremendous development of the Internet for both marketing and e-commerce settings, in conjunction with the growing desire of consumers to purchase online, has promoted two main outcomes: (a) increasing numbers of Business-to-Customer companies running businesses online and (b) the development of a variety of different e-loyalty research models. However, current research lacks a systematic review of the literature that provides a general conceptual framework on e-loyalty, which would help managers to understand their customers better, to take advantage of industry-related factors, and to improve their service quality. The present study is an attempt to critically synthesize results from multiple empirical studies on e-loyalty. Our findings illustrate that 62 instruments for measuring e-loyalty are currently in use, influenced predominantly by Zeithaml et al. (J Marketing. 1996;60(2):31-46) and Oliver (1997; Satisfaction: a behavioral perspective on the consumer. New York: McGraw Hill). Additionally, we propose a new general conceptual framework, which leads to antecedents dividing e-loyalty on the basis of the action of purchase into pre-purchase, during-purchase and after-purchase factors. To conclude, a number of managerial implementations are suggested in order to help marketing managers increase their customers’ e-loyalty by making crucial changes in each purchase stage

Computerization of workflows, guidelines and care pathways: a review of implementation challenges for process-oriented health information systems
There is a need to integrate the various theoretical frameworks and formalisms for modeling clinical guidelines, workflows, and pathways, in order to move beyond providing support for individual clinical decisions and toward the provision of process-oriented, patient-centered, health information systems (HIS). In this review, we analyze the challenges in developing process-oriented HIS that formally model guidelines, workflows, and care pathways. A qualitative meta-synthesis was performed on studies published in English between 1995 and 2010 that addressed the modeling process and reported the exposition of a new methodology, model, system implementation, or system architecture. Thematic analysis, principal component analysis (PCA) and data visualisation techniques were used to identify and cluster the underlying implementation ‘challenge’ themes. One hundred and eight relevant studies were selected for review. Twenty-five underlying ‘challenge’ themes were identified. These were clustered into 10 distinct groups, from which a conceptual model of the implementation process was developed. We found that the development of systems supporting individual clinical decisions is evolving toward the implementation of adaptable care pathways on the semantic web, incorporating formal, clinical, and organizational ontologies, and the use of workflow management systems. These architectures now need to be implemented and evaluated on a wider scale within clinical settings
Vodcast Impact on Students\u27 Attitudes and Behavioral Intentions
Purpose: This paper uses structural equation modeling to assess the effectiveness of Vodcasts (video podcasts) as part of a university’s communication strategy with prospective students. Design/methodology/approach: Three theoretical models were tested using a structural equation model. Findings: We find that perceived informativeness, credibility, and irritation of the advertising are directly related to the value of the Vodcast advertising. However of those three factors, only the informativeness is directly related to the intent to take further action toward enrollment. In addition, while prior work has suggested that perceived entertainment of advertising positively influences its perceived value, we find that for these university Vodcasts, perceived entertainment is not a statistically significant factor. Research limitations/implications: The results suggest that for Vodcasts used for these purposes, less attention should be given to entertainment value, and more attention should be focused on providing useful information in a manner that is credible and not irritating to students. Originality/value: Vodcasts have become part of the Internet multimedia experience and have been integrated into universities’ web-based promotion strategies. While prior work has examined general advertising on the web, few studies have considered the impact of the interactive medium of Vodcasts on attitudes and behavioral intentions
Psychological elements explaining the consumer's adoption and use of a website recommendation system: A theoretical framework proposal
The purpose of this paper is to understand, with an emphasis on the psychological perspective of the research problem, the consumer's adoption and use of a certain web site recommendation system as well as the main psychological outcomes involved. The approach takes the form of theoretical modelling. Findings: A conceptual model is proposed and discussed. A total of 20 research propositions are theoretically analyzed and justified. Research limitations/implications: The theoretical discussion developed here is not empirically validated. This represents an opportunity for future research. Practical implications: The ideas extracted from the discussion of the conceptual model should be a help for recommendation systems designers and web site managers, so that they may be more aware, when working with such systems, of the psychological process consumers undergo when interacting with them. In this regard, numerous practical reflections and suggestions are presented
Conceptual models of urban environmental information systems - toward improved information provision
Cities are the hub of European society - for over a millennium, they are the locus of social, political
and economic development. As the core of intensive and creative human activity, they are also the
place where the environmental externalities that accompany rapid development are most visible.
The environmental consequences of urban development have been recognised long ago, as in the
case of London, where in 1388 legislation was introduced to control pollutant emissions
(Lowenthal, 1990). Similar historical environmental regulations can be demonstrated for many
cities in Europe. However, while for most of history those who govern the city (be it the sovereign,
city elders or local government) where responsible for the control, mitigation and management of
the common environment in the city, the last 30 years are a period of profound change. This is due
to the trend toward improved participation in environmental decision making . a more inclusive and
open approach to decisions that deal with the city commons. This change did not occurre overnight
but rather gradually. For example, in the United Kingdom, it was the Town and Country Planning
Act of 1947 which introduced public scrutiny to changes in the urban form (Rydin, 1998), or the
development of public involvement in environmental impact assessment of urban projects as
developed in many countries throughout the developed world during the 1970s and 1980s (Gilpin
1995). These changes accelerate within the last three decades, and especially since the publication
of .Our Common Future. (WCED and Brundtland 1987), the acceptance of the .Sustainable
Development. principles and the Rio conference. A quiet (mini) revolution happened in Europe not
long ago, toward the end of 1998 when the members of the United Nations Economic Commission
for Europe (UN/ECE) signed the .Convention on Access to Information, Public Participation in
Decision Making and Access to Justice in Environmental Matters. - the Aarhus Convention
(UN/ECE 1998). The convention is expected to come into force by the end of 2001, and calls the
governments and public authorities to open up access to environmental information as a means to
improve public participation in environmental decision making and awareness of environmental
issues (UN/ECE, 1998).
However, these declarations on the value and importance of environmental information do not
match our level of understanding on the role of environmental information in decision making
processes, and especially on the role of information in improving awareness and participation.
Therefore, it is useful to take a step back, and to try and evaluate how environmental information
and access to it and its use support public involvement in such processes.
This paper is aimed to offer a framework that can assist us in the analytical process of
understanding environmental information use. It focuses on public access and assumes that
environmental information will be delivered to the public through the Internet. Such assumption is
based on the current trend within public authorities is to use Information and Communication
Technology (ICT) as a major delivery medium and it seems that it will become more so in the near
future (OECD 2000).
The framework which this paper presents, is based on Soft Systems Methodology (SSM) study
which unpacked some of the core issues relating to public access and use of environmental
information (Haklay, 2001). Although the aim here is not to discuss the merits of SSM, but to focus
on the conceptual models, some introduction to the techniques that are used here is needed.
Therefore, the following section opens with introduction to SSM and its techniques. The core of the
paper is dedicated to the development of conceptual models. After presenting the conceptual
models, some conclusions about these models and their applications are drown
Web Acceptance and Usage Model: A Comparison between Goal-directed and Experiential Web Users
In this paper we analyse the Web acceptance and usage between goal-directed users and experiential users, incorporating intrinsic motives to improve the particular and explanatory TAM value –traditionally related to extrinsic motives-. A field study was conducted to validate measures used to operationalize model variables and to test the hypothesised network of relationships. The data analysis method used was Partial Least Squares (PLS).The empirical results provided strong support for the hypotheses, highlighting the roles of flow, ease of use and usefulness in determining the actual use of the Web among experiential and goal-directed users. In contrast with previous research that suggests that flow would be more likely to occur during experiential activities than goal-directed activities, we found clear evidence of flow for goal-directed activities. In particular the study findings indicate that flow might play a powerfulrole in determining the attitude towards usage,intention to useand, in turn,actual Web use among experiential and goal-directed users
A probabilistic model to resolve diversity-accuracy challenge of recommendation systems
Recommendation systems have wide-spread applications in both academia and
industry. Traditionally, performance of recommendation systems has been
measured by their precision. By introducing novelty and diversity as key
qualities in recommender systems, recently increasing attention has been
focused on this topic. Precision and novelty of recommendation are not in the
same direction, and practical systems should make a trade-off between these two
quantities. Thus, it is an important feature of a recommender system to make it
possible to adjust diversity and accuracy of the recommendations by tuning the
model. In this paper, we introduce a probabilistic structure to resolve the
diversity-accuracy dilemma in recommender systems. We propose a hybrid model
with adjustable level of diversity and precision such that one can perform this
by tuning a single parameter. The proposed recommendation model consists of two
models: one for maximization of the accuracy and the other one for
specification of the recommendation list to tastes of users. Our experiments on
two real datasets show the functionality of the model in resolving
accuracy-diversity dilemma and outperformance of the model over other classic
models. The proposed method could be extensively applied to real commercial
systems due to its low computational complexity and significant performance.Comment: 19 pages, 5 figure
