The improvement of ICT infrastructure, developing ICT knowledge and usage can lead to economic growth due to higher productivity. However, this impact can depend on countries' ICT investment or expenditure amount, reached ICT development and productivity levels. Moreover, ICT impact on productivity growth can occur after a certain period. Consequently, forming the ICT development strategies it is important to identify ICT impact period and impact differences between relatively high and low productivity countries. Authors examined the impact of ICT investments on productivity in EU countries covering the period of 1995–2015. Research results have revealed that ICT development positively and directly influences productivity, but this effect manifests with a lag in time. Moreover, it was found that the impact of ICT development on productivity is about twice bigger in countries with relatively high productivity level compared with countries that have relatively low productivity level.","PeriodicalId":340536,"journal":{"name":"Int.

Despite the short life of most of the financial companies in the Albanian trade market, results show that executives have a relatively good level of knowledge regarding the benefits of the innovation approach to the firm, but there is a lack of some innovation types used by their companies. Furthermore, there is a low level of investment amount to be spent in innovation, indicating a non-possibility to create new products or processes and thus not having the possibility to be a leader and create better promise for the company growth. Government is advised to consider innovation as a mediating factor to achieve better business performance and thus helping and promoting sustainable macroeconomic growth.","PeriodicalId":340536,"journal":{"name":"Int.

The four business dimensions of green IT transformation, namely, economy, technology, people, and process are used in this study in the context of an Indian IT organisation. Though green IT transformation is unique for every organisation, a case of a particular organisation can provide a roadmap for other companies to develop such green IT transformation. Our analysis brings out the status of transformation in all four dimensions and recommendations are drawn to fine-tune the green IT transformation based on the findings.","PeriodicalId":340536,"journal":{"name":"Int.

This study extends the literature on information systems (ISs) integration by providing insights into a set of interrelationships that are relevant for the attainment of firm profitability from IS integration. The conceptual model for fitness evaluation was developed by literature review. The purpose of this paper is to develop a comprehensive model for fitness evaluation and to determine a fitness index using fuzzy methods. To test the hypotheses, we employed a multi-case study methodology. An evaluation of the improvement in efficiency of the processes was conducted on 21 medium sized enterprises (SMEs) which produce on the basis of orders, and have implemented a system of (ERP), in order to check the progress of each order and to increase the efficiency of the processes they are connected to.","PeriodicalId":340536,"journal":{"name":"Int.

One of the possible ways in achieving this goal is to get rid of the uncommon activities to intermediaries, which take control over the process of distribution of goods. However, due to intense change on the market, intermediaries responsible for provision of third-party logistics (3PL) services, sometimes fall short to adapt to shifted manufacturer's needs. Because of the insufficient exchange of information, 3PL service providers start to render inadequate services and are not able to assure efficiency of manufacturer's logistics system. This article discusses importance of exchange of information between production enterprises and their logistics intermediaries based on the results of study on the situation of communication problems between 3PL service providers and their clients in Lithuania.","PeriodicalId":340536,"journal":{"name":"Int.

Our results suggest that perceived value, social presence, interactivity, and trustworthiness are positively related to the user's attitude towards social media.

Top management support is considered one of the most, if not the most, critical factors for implementation success. However, the positive effect of top management support is not always borne out in empirical data, prompting a quest for moderator variables. A classic meta-analysis shows that the effect of top management support on implementation success is moderated by task interdependence, a claim refuted in several more recent meta-analyses. Drawing from the lessons learned from these meta-analyses, the current research reanalysed the top management support literature with a larger sample while controlling for the effect of common method variance and systems success measurement issues. The results reaffirm the significant and substantial effect of top management support on systems success. At the same time, evidence also supports the moderating role of task interdependence, common method variance, and how systems success is measured. Implications for systems implementation are discussed.","PeriodicalId":340536,"journal":{"name":"Int. J. Inf. Technol.

We use skew and kurtosis in order to define test sets instead of simply choosing a range of shape parameters.

Furthermore, an effective performance prediction mechanism is of significant value for improving the current cloud services, such as resource allocation and task scheduling. In the paper, we present the design and prototype implementation of a performance prediction system, namely cloud performance prediction middleware (CPPM), which is aiming at providing a set of lightweight and flexible services on existing cloud infrastructure so as to allow cloud providers monitoring, estimating and predicting the runtime performance from various aspects. The CPPM enables cloud providers to make more efficient and fine-grained resource management and scheduling policies based on their short-term workload prediction mechanism; also it provides an application-level performance prediction service which uses skeleton approach to capture execution characteristics of the running applications so as to predict their actual runtime performance and efficiency. Extensive experiments are conducted to examine the effectiveness and efficiency of the CPPM.","PeriodicalId":340536,"journal":{"name":"Int. J. Inf. Technol.

Firstly, this paper analysis the inherent parallelism of the naive Bayesian regression model and constructs the theoretical model of naive Bayesian parallelisation. Secondly, the parallel naive Bayes regression model-based collaborative filtering recommendation algorithm is realised on Hadoop platform with distributed Hadoop distributed file system (HDFS) and MapReduce as the transparent distributed infrastructure. And its temporal-spatial overhead, speedup is discussed. Finally, applying parallel the naive Bayes regression model-based collaborative filtering recommendation algorithm to a large dataset.
