Enterprise social media and cyber-slacking: A Kahn’s model perspective
2021
Abstract This study investigates the associations between enterprise social media (ESM) use, psychological conditions, and cyber-slacking in the workplace and examines the mediating role of psychological conditions between ESM use and cyber-slacking. The study utilizes Kahn’s framework to develop a research model and investigate various associations, and it employs a cross-sectional design, testing the developed research model with 277 ESM users from Chinese enterprises. The study results suggest that ESM use stimulates various psychological conditions that discourage cyber-slacking behaviors and significantly mediate the associations between ESM use and cyber-slacking.
ERP systems success: an empirical analysis of how two organizational stakeholder groups prioritize and evaluate relevant measures
2007
Organizations worldwide are adopting enterprise resource planning (ERP) systems. A number of studies discuss the implementation and success of such systems, but our study of the literature indicates that discussions about ERP systems success from the perspectives of key organizational stakeholders are not easy to come across. This study is designed to fill this gap in research. Using surveys in Finland and Estonia, we obtained empirical data from 66 respondents in 44 diverse, private, industrial organizations. Our objective was to determine whether differences exist between two organizational stakeholder groups, i.e. business managers and IT professionals, concerning how each group believe …
Implications of Theories of Language for Information Systems
1985
This article demonstrates how language views can be adopted into an information systems context. We distinguish here between five language views: denotational, generative, cognitive, behavioristic, and interactionist. These views differ in their assumptions about he origin of linguistic behavior, the primary functions of language, elements of language, and the nature of linguistic knowledge. Information system development approaches can be characterized by their underlying language views. This explains great differences in development methods and research. Thus, language views have implications and should be chosen continency for a given information system context.
Bundle generation for last-mile delivery with occasional drivers
2022
In this paper, we present the vehicle routing problem (VRP) with occasional drivers (OD) and order bundles (OB). The problem VRP-OD-OB is an extension of the VRP-OD, where instead of assigning one customer per driver, drivers are assigned bundles of customers. To deal with the bundle-to-driver assignment, a bidding system is exploited, in which a company offers a set of bundles and the drivers raise their bids. These bids depend on features such as the drivers’ destination, flexibility in deviating from the shortest path, and willingness to offer service. To generate valuable bundles of customers, we propose two strategies: (i) an innovative approach based on the creation of corridors, and …
Modelling and forecasting mortality in Spain
2008
[EN] Experience shows that static life tables overestimate death probabilities. As a consequence of this overestimation the premiums for annuities, pensions and life insurance are not what they actually should be, with negative effects for insurance companies or policy-holders. The reason for this overestimation is that static life tables, through being computed for a specific period of time, cannot take into account the decreasing mortality trend over time. Dynamic life tables overcome this problem by incorporating the influence of the calendar when graduating mortality. Recent papers on the topic look for the development of new methods to deal with this dynamism. Most methods used in dyna…
A Bibliometric Analysis of the Spanish Scientific Production on Teaching Oral Communication Between 2010 and 2020
2022
This research paper aims to analyse the visibility, scientific production and educational impact of teaching spoken language between 2010 and 2020 by using bibliometric techniques. The Scopus and Web of Science databases have been used in order to carry out the study. We have selected articles published in journals included in the thematic category of Teaching Oral Communication in the decade 2010-2020. Out of 2677 articles, only 457 offer relevant data for our analysis, and of these, no more than 155 documents are written by Spanish authors. The lack of articles on this topic seems obvious, which consequently leads to the conclusion that there is a high need to conduct rigorous research on…
Toward a Unified Model of Information Security Policy Compliance
2018
Information systems security (ISS) behavioral research has produced different models to explain security policy compliance. This paper (1) reviews 11 theories that have served the majority of previous information security behavior models, (2) empirically compares these theories (Study 1), (3) proposes a unified model, called the unified model of information security policy compliance (UMISPC), which integrates elements across these extant theories, and (4) empirically tests the UMISPC in a new study (Study 2), which provided preliminary empirical support for the model. The 11 theories reviewed are (1) the theory of reasoned action, (2) neutralization techniques, (3) the health belief model,…
Testing Prospect Theory in a Deterministic Multiple Criteria Decision-Making Environment
1993
Prospect theory by Kahneman and Tversky [7] is tested in a deterministic multiple criteria decision-making context. In two experiments conducted in classroom settings subjects made pairwise preference comparisons of condominiums for sale. The results of the experiments indicate that the traditional value model did not explain the subjects' revealed preferences as well as the prospect model. We conclude that prospect theory is a reasonable model of choice for many individuals in such a context.
An ant colony optimization-based fuzzy predictive control approach for nonlinear processes
2015
In this paper, a new approach for designing an adaptive fuzzy model predictive control (AFMPC) based on the ant colony optimization (ACO) is proposed. On-line adaptive fuzzy identification is introduced to identify the system parameters. These parameters are used to calculate the objective function based on a predictive approach and structure of RST control. Then the optimization problem is solved based on an ACO algorithm, used at the optimization process in AFMPC to determine optimal controller parameters of RST control. The utility of the proposed controller is demonstrated by applying it to two nonlinear processes, where the proposed approach provides better performances compared with p…
Do Foreign Direct Investment (FDI) and Trade Openness Explain the Disparity in ICT Diffusion between Asia-Pacific and the Islamic Middle Eastern Coun…
2010
This study investigates the impact of FDI and trade openness on ICT diffusion in the Asia-Pacific and Middle East regions from 1996-2005. The results indicate that while dissimilarities exist between the economies included in this study in terms of their level of socio-economic and political development, education and the growth of GDP have had a positive impact on ICT diffusion in both regions. However, while FDI has generally had a positive and significant impact on ICT diffusion in Asia-Pacific economies, its impact on Middle Eastern economies has been detrimental. The results of this study also show that trade-openness has had, in general, a positive and significant impact on ICT diffus…
