The effect of social media communication on consumer perceptions of brands

Researchers and brand managers have limited understanding of the effects social media communication has on how consumers perceive brands. We investigated 504 Facebook users in order to observe the impact of firm-created and user-generated social media communication on brand equity, brand attitude and purchase intention by using a standardized online survey throughout Poland. To test the conceptual model, we analyzed 60 brands across three different industries: non-alcoholic beverages, clothing and mobile network operators. When analyzing the data, we applied the structural equation modeling technique to both investigate the interplay of firm-created and user-generated social media communication and examine industry-specific differences. The results of the empirical studies showed that user-generated social media communication had a positive influence on both brand equity and brand attitude, whereas firm-created social media communication affected only brand attitude. Both brand equity and brand attitude were shown to have a positive influence on purchase intention. In addition, we assessed measurement invariance using a multi-group structural modeling equation. The findings revealed that the proposed measurement model was invariant across the researched industries. However, structural path differences were detected across the models

Nomadic input on mobile devices: the influence of touch input technique and walking speed on performance and offset modeling

In everyday life people use their mobile phones on-the-go with different walking speeds and with different touch input techniques. Unfortunately, much of the published research in mobile interaction does not quantify the influence of these variables. In this paper, we analyze the influence of walking speed, gait pattern and input techniques on commonly used performance parameters like error rate, accuracy and tapping speed, and we compare the results to the static condition. We examine the influence of these factors on the machine learned offset model used to correct user input and we make design recommendations. The results show that all performance parameters degraded when the subject started to move, for all input techniques. Index finger pointing techniques demonstrated overall better performance compared to thumb-pointing techniques. The influence of gait phase on tap event likelihood and accuracy was demonstrated for all input techniques and all walking speeds. Finally, it was shown that the offset model built on static data did not perform as well as models inferred from dynamic data, which indicates the speed-specific nature of the models. Also, models identified using specific input techniques did not perform well when tested in other conditions, demonstrating the limited validity of offset models to a particular input technique. The model was therefore calibrated using data recorded with the appropriate input technique, at 75% of preferred walking speed, which is the speed to which users spontaneously slow down when they use a mobile device and which presents a tradeoff between accuracy and usability. This led to an increase in accuracy compared to models built on static data. The error rate was reduced between 0.05% and 5.3% for landscape-based methods and between 5.3% and 11.9% for portrait-based methods

The role of intrinsic and extrinsic motivations in sharing economy post-adoption

Oliveira, T., Barbeitos, I., & Calado, A. (2022). The role of intrinsic and extrinsic motivations in sharing economy post-adoption. Information Technology and People, 35(1), 165-203. https://doi.org/10.1108/ITP-01-2020-0007Purpose: The purpose of this paper is to examine use and sharing economy (SE) continuance intention, and the mediation effects of use between individuals' motivations and SE continuance intention. A theoretical model is developed to explain use and SE continuance intention as intrinsic and extrinsic motivated behaviour, as proposed by self-determination theory. Factors are derived from SE context and supported by published research on SE. Design/methodology/approach: The partial least squares path modelling (PLS-PM) technique is used to test the model in a quantitative study involving 256 users of SE services. Findings: Findings suggest that use and SE continuance can be explained by concurrent intrinsic and extrinsic motivations. Moreover, high environmental concerns may restrain the use of SE services. Findings show that continuance intention is influenced by current use of SE services. Moreover, the study emphasizes the mediation effect of use between intrinsic and extrinsic motivation and SE continuance intention. Research limitations/implications: The analysis of use behaviour should be complemented with other measures of use and with data provided by qualitative methods of research. Further research should also consider the effect of different control variables and mediation effects. Practical implications: Brand managers and companies providing services through digital platforms should address individuals' needs in order to stimulate voluntary engagement in persistent SE practices. Social implications: This study informs the consumer in general so that the SE can develop its potential alongside an economy based on the ownership of private property. Originality/value: This study extends findings on continuance intention research by offering internal motivation factors as predictors of post-adoption behaviour and emphasizes the role of use on SE continuance intention.authorsversionpublishe

OpenKnowledge at work: exploring centralized and decentralized information gathering in emergency contexts

Real-world experience teaches us that to manage emergencies, efficient crisis response coordination is crucial; ICT infrastructures are effective in supporting the people involved in such contexts, by supporting effective ways of interaction. They also should provide innovative means of communication and information management. At present, centralized architectures are mostly used for this purpose; however, alternative infrastructures based on the use of distributed information sources, are currently being explored, studied and analyzed. This paper aims at investigating the capability of a novel approach (developed within the European project OpenKnowledge1) to support centralized as well as decentralized architectures for information gathering. For this purpose we developed an agent-based e-Response simulation environment fully integrated with the OpenKnowledge infrastructure and through which existing emergency plans are modelled and simulated. Preliminary results show the OpenKnowledge capability of supporting the two afore-mentioned architectures and, under ideal assumptions, a comparable performance in both cases

Electronic fraud detection in the U.S. Medicaid Healthcare Program: lessons learned from other industries

It is estimated that between $600 and$850 billion annually is lost to fraud, waste, and abuse in the US healthcare system,with $125 to$175 billion of this due to fraudulent activity (Kelley 2009). Medicaid, a state-run, federally-matchedgovernment program which accounts for roughly one-quarter of all healthcare expenses in the US, has been particularlysusceptible targets for fraud in recent years. With escalating overall healthcare costs, payers, especially government-runprograms, must seek savings throughout the system to maintain reasonable quality of care standards. As such, the need foreffective fraud detection and prevention is critical. Electronic fraud detection systems are widely used in the insurance,telecommunications, and financial sectors. What lessons can be learned from these efforts and applied to improve frauddetection in the Medicaid health care program? In this paper, we conduct a systematic literature study to analyze theapplicability of existing electronic fraud detection techniques in similar industries to the US Medicaid program

Scenarios and research issues for a network of information

This paper describes ideas and items of work within the framework of the EU-funded 4WARD project. We present scenarios where the current host-centric approach to infor- mation storage and retrieval is ill-suited for and explain how a new networking paradigm emerges, by adopting the information-centric network architecture approach, which we call Network of Information (NetInf). NetInf capital- izes on a proposed identifier/locator split and allows users to create, distribute, and retrieve information using a com- mon infrastructure without tying data to particular hosts. NetInf introduces the concepts of information and data ob- jects. Data objects correspond to the particular bits and bytes of a digital object, such as text file, a specific encod- ing of a song or a video. Information objects can be used to identify other objects irrespective of their particular dig- ital representation. After discussing the benefits of such an indirection, we consider the impact of NetInf with respect to naming and governance in the Future Internet. Finally, we provide an outlook on the research scope of NetInf along with items for future work

POLICY OF NATIONALISM GUIDANCE THROUGH IN TRADITIONAL MARKET MANAGEMENT IN CENTRAL JAVA

A research on policy nationalism guidance through in traditional markets management in the province of Central Java is implemented in “Pasar Gede Solo” with qualitative methods. The reason for selecting “Pasar Gede Solo” because of Solo City has a lot of cultural heritages that are still held strong until today. The cultural heritage is the local identity. The Local identity can develop into the province identity, then to be the national identity. A strong national identity shows high Nationalism which reflected from loyalty, passion and pride of the nation itself. The number of local identities in “Pasar Gede Solo” is likely to evolve into national identity should be encouraged to preserve the Government's policy to strengthen Indonesia Nationalism
