Is there a Link between Sustainability, Perception and Buying Decision at the Point of Sale?

Publié en ligne: 03 Dec 2020
Pages: 1 - 13

Résumé

Abstract Background

If retailers and brand manufacturers of food succeed in presenting their products at the point of sale, quickly generating a high level of attention, the likelihood of a purchase is significantly increased. Particularly, in recent years, they have been relying on the megatrend of sustainability. The importance of sustainable food has grown accordingly. Hence, an increasing number of manufacturers are challenged to communicate the sustainability of their products via packaging and displays at the point of sale.

Objectives

The aim of this article is: to examine to what extent the design of individual packaging and display elements of new sustainable direct juice succeeds in visually communicating sustainability aspects. At the same time the willingness to pay of customers interested in sustainability must be commercialized.

Methods/Approach

The focus is on a real shopping situation in conditions that are as regular as possible. The perception of a display must be recorded by eye-tracking technology. A preliminary survey must examine consumers' attitudes towards sustainable food in order to relate it to the perception of individual display elements. For this purpose, the eye-tracking technology was combined with a survey of 32 customers.

Results

The results demonstrate that customers with a positive attitude towards sustainable food behave in the following way: they fix individual packaging and display elements that refer to sustainable components for a longer period of time; they remember product features better and they tend to have a slightly higher willingness to pay for the sustainable direct juice.

Conclusions

The configuration of an authentic and natural shopping situation provides the manufacturer with concrete recommendations for the design of the display. This communicates the sustainability of its product and thus generates the desired attention.

How Impulsivity influences the Post-purchase Consumer Regret?

Publié en ligne: 03 Dec 2020
Pages: 14 - 29

Résumé

Abstract Background

The role of impulsivity in post-purchase consumer regret is unclear and intriguing because of the negative emotions that underlie both constructs. It is particularly important to examine the impact of impulsivity on the relationship between regret and the Emotionality dimension of the HEXACO model of personality.

Objectives

The purpose of this paper was to investigate the associations between consumer regret components: outcome regret and process regret, attention, motor and non-planning dimensions of impulsivity and Fearfulness, Anxiety, Dependence and Sentimentality domains of Emotionality.

Methods/Approach

The sample consisted of undergraduates from Zagreb, Croatia (Mage = 25.93, 56% females). The correlation and the regression analysis were performed. We used the Baratt impulsivity scale (BIS-11), the HEXACO-PI-R Emotionality scale and the Post Purchase Regret Scale (PPRS).

Results

The PPCR total score was associated with the BIS-11 total score, attention and non-planning impulsivity. Regret due to foregone alternatives was related to attention and non-planning impulsivity, while regret due to a change in significance was related only to attention impulsivity. Regret due to under-consideration positively correlated with non-planning impulsivity.

Conclusions

The results indicate that relations between impulsivity and consumer regret have an important role in understanding consumer behavior and that impulsivity has a moderate association between consumer regret and Emotionality.

R&D Investments in the European ICT sector: Implications for Business Performance

Publié en ligne: 03 Dec 2020
Pages: 30 - 44

Résumé

Abstract Background

A significant share of business innovation arises from information and communication (ICT) sector. Business investment into research and development (R&D) activities can be seen as an important basis for innovation, which can further lead to better economic performance. This can be especially true for the ICT sector.

Objectives

The paper examines the share of the ICT sector on innovation and the total R&D expenditure in selected European countries. Furthermore, our aim is to test the potential positive correlation between R&D expenditure, productivity and the value added in the sector.

Methods/Approach

The goals of the paper has been tested by empirical data analysis using the pane regression analysis. We examined panel data for 24 European countries in the 2008-2016 period.

Results

The highest share of business R&D expenditure in ICT has been captured in Nordic countries. Firms in ICT appear to be innovative above the average and represent a significant share in the total business R&D expenditure.

Conclusions

We found a positive correlation between R&D expenditure and both value-added and apparent labour productivity in the ICT sector. We believe that this could be to some extent attributed to the innovation of products and processes. Hence, the government support in the form of R&D tax incentives can be also beneficial for the economic performance of ICT firms.

Testing the Twin Deficit Hypothesis: Evidence from the Republic of North Macedonia

Publié en ligne: 03 Dec 2020
Pages: 45 - 62

Résumé

Abstract Background

An econometric analysis of the twin deficit hypothesis is of special importance for the Republic of North Macedonia in view of its perspective membership in the European Union and from the point of view of its macroeconomic stability in the long run.

Objectives

The objective of this paper is to test empirically the validity of the twin deficit hypothesis in the Republic of North Macedonia.

Methods/Approach

To achieve this objective, we used actual quarterly data on Macedonia's budget and the current account deficit in the period from the first quarter of 2005 until the fourth quarter of 2017 and applied several econometrics methods: the Granger causality, a vector autoregressive (VAR) and a vector error correction model (VECM).

Results

These findings point to the conclusion that efforts focused on improving the current account imbalances through fiscal policy will be inefficient in the short run.

Conclusions

However, the existence of a long run relationship between the budget deficit and the current account deficit indicates the necessity of policy initiatives focused not only on reducing the budget deficit, but also on improving the external position of the country though export promotion.

Pages: 63 - 77

Résumé

Abstract Background

The automotive world is on the threshold of a new era. Manufacturers are transforming themselves into suppliers of mobility services. Fundamentals for the transformation are customer processes combined with connectivity driven by the Internet of Things. Mobile payment serves as an enabler to most of these services.

Objectives

This paper demonstrates promising ways how payment-enabled services in the context of connected cars can be designed based on the process thinking approach.

Methods/Approach

In this paper, the methodology of use cases is applied as a means to develop services for the connected car through process thinking. The use case studied is validated afterwards with industry experts following a semi-structured interview format.

Results

The use case investigated in the course of the paper suggests that the core characteristics and challenges of these services are already predictable ex-ante by the theoretical framework on which the paper is built upon. In particular, the paper shows the steps needed for a driver’s request for on-demand horsepower for a certain time span along with mobile payment for this service.

Conclusions

It is concluded that the connectivity paradigm supplemented by mobile payment options enables consistent implementation of customer centricity in terms of process thinking.

Optimizing the Resource Consumption of Blockchain Technology in Business Systems

Publié en ligne: 03 Dec 2020
Pages: 78 - 92

Résumé

Abstract Background

Blockchain technology has gained a great public interest due to the appearance of cryptocurrencies, a digital asset used for exchanging funds. Although blockchain calculations offer the benefits of security and reduced costs, blockchain is still strongly criticised for its lack of usefulness and resource-heavy consumption.

Objectives

The aim of this research is to provide different insights into blockchain technology and to propose NP-complete problems as a suitable alternative to the current consensus algorithm.

Methods/approach

This research discusses the current state of proposed alternatives, projects such as distributed volunteering for scientific purposes and different consensus algorithms within cryptocurrencies but focusing on incorporating NP-complete problems as a secondary, more useful option.

Results

Using the properties of NP-complete problems, it is possible to solve various problems in different areas, such as science, biology, medicine and finance, but also to improve business processes, optimize markets, payments and supply chains while decreasing environmental costs.

Conclusions

This paper shows that the alternative mechanisms are being developed and used to substitute an existing Blockchain algorithm with a more efficient one. It also suggests further investigation in this area because the alternatives greatly improve blockchain’s usability and efficiency.

BlockChain Platforms in Financial Services: Current Perspective

Publié en ligne: 03 Dec 2020
Pages: 110 - 126

Résumé

Abstract Background

BlockChain technology was invented to support bitcoin, currently the most popular virtual currency.

Objectives

The purpose of this paper is to investigate contemporary BlockChain platforms in financial services.

Methods/Approach

An unstructured literature review has been used.

Results

BlockChain in financial services is mostly associated with bitcoin exchange. However, this is a partial view of both BlockChain technology and its possible adoption for financial services: in fact, many BlockChain platforms are now available and many different financial services can be effectively supported by BlockChain platforms, even though they are not based on virtual-money exchange. Furthermore, people are attracted by the concept of smart contract, i.e., a contract that is automatically executed by computer technology, without human intervention.

Conclusions

The contribution of this paper is twofold: first of all, we introduce the four BlockChain platforms that are now most popular, discussing how they support the smart contract concept; second, we identify some typical categories of financial services, matching each of them with the platform that provides the best support for each category.

Data Mining Applications in SMEs: An Italian Perspective

Publié en ligne: 03 Dec 2020
Pages: 127 - 146

Résumé

Abstract Background

From the last decade, data mining techniques, employed in particular in customer relationship management, have assumed a key role in the profitability and operations of companies. To support small and medium companies (SMEs), several innovative and continuously improving tools have been developed that allow SMEs to utilize the internal and external data sources to increase their competitiveness.

Objectives

In this paper, an analysis of the impact of digitalization, and in particular data mining techniques, in the context of SMEs development is presented.

Methods/Approach

A review of various sources has been conducted, with the focus on open source tools, since in the context of the Italian economy they are used by SMEs the most.

Results

First, the analysis presents a brief review of the data mining techniques available and shows how they are practically employed in small companies. Second, an economical review of investments in data mining projects in Italy is presented.

Conclusions

The review indicates that data mining techniques can boost a company in the market. However, the awareness of data mining as a company asset is still not strong in Italian SMEs and most investments in Italy are still carried out by large companies.

Intelligent Personal Assistant in Business-Context: Key-feature Evaluation for User Acceptance

Publié en ligne: 03 Dec 2020
Pages: 147 - 166

Résumé

Abstract Background

The usage of intelligent personal assistants (IPA), such as Amazon Alexa or Google Assistant is increasing significantly, and voice-interaction is relevant for workflows in a business context.

Objectives

This research aims to determine IPA characteristics to evaluate the usefulness of specific functions in a simulated production system of an Enterprise Resource Planning (ERP) software. A new function called explanation-mode is introduced to the scientific community and business world.

Methods/Approach

As part of a design science research, an artefact, i.e. an add-on for speech-interaction in business software, was developed and evaluated using a survey among ERP users and researchers.

Results

In the area of IPA-features, the search-function and speech input for textual fields were recognised as most useful. The newly introduced feature, the explanation mode, was positively received too. There is no significant correlation between the usefulness of features and participant-characteristics, affinity to technology or previous experience with IPAs in a private context, which is in line with previous studies in the private environment leading to the conclusion that the task attraction is the most important element for usefulness.

Conclusions

Most of the participants agreed that the speech-input is not able to fully substitute standard input devices, such as a keyboard or a mouse, so the IPA is recognised as an addition to traditional input methods. The usefulness is rated high especially for speech-input for long text fields, calling up masks and search-functions.

IoT and Smart Home Data Breach Risks from the Perspective of Data Protection and Information Security Law

Publié en ligne: 03 Dec 2020
Pages: 167 - 185

Résumé

Abstract Background

IoT and smart devices have become extremely popular in the last few years. With their capabilities to collect data, it is reasonable to have concerns about the protection of users’ personal information and privacy in general.

Objectives

Comparing existing regulations on data protection and information security rules with the new capabilities provided by IoT and smart devices.

Methods/approach

This paper will analyse information on data collected by IoT and smart devices and the corresponding legal framework to explore whether the legal framework also covers these new devices and their functionalities.

Results

Various IoT and smart devices pose a high risk to an individual's privacy. The General Data Protection Regulation, although a relatively recent law, may not adequately regulate all instances and uses of this technology. Also, due to inadequate technological protection, abuse of such devices by unauthorized persons is possible and even likely.

Conclusions

The number of IoT and smart devices is rapidly increasing. The number of IoT and smart home device security incidents is on the rise. The regulatory framework to ensure data controller and processor compliance needs to be improved in order to create a safer environment for new innovative IoT services and products without jeopardizing the rights and freedoms of data subjects. Also, it is important to increase awareness of homeowners about potential security threats when using IoT and smart devices and services.

From the last decade, data mining techniques, employed in particular in customer relationship management, have assumed a key role in the profitability and operations of companies. To support small and medium companies (SMEs), several innovative and continuously improving tools have been developed that allow SMEs to utilize the internal and external data sources to increase their competitiveness.

Objectives

In this paper, an analysis of the impact of digitalization, and in particular data mining techniques, in the context of SMEs development is presented.

Methods/Approach

A review of various sources has been conducted, with the focus on open source tools, since in the context of the Italian economy they are used by SMEs the most.

Results

First, the analysis presents a brief review of the data mining techniques available and shows how they are practically employed in small companies. Second, an economical review of investments in data mining projects in Italy is presented.

Conclusions

The review indicates that data mining techniques can boost a company in the market. However, the awareness of data mining as a company asset is still not strong in Italian SMEs and most investments in Italy are still carried out by large companies.

Intelligent Personal Assistant in Business-Context: Key-feature Evaluation for User Acceptance

Publié en ligne: 03 Dec 2020
Pages: 147 - 166

Résumé

Abstract Background

The usage of intelligent personal assistants (IPA), such as Amazon Alexa or Google Assistant is increasing significantly, and voice-interaction is relevant for workflows in a business context.

Objectives

This research aims to determine IPA characteristics to evaluate the usefulness of specific functions in a simulated production system of an Enterprise Resource Planning (ERP) software. A new function called explanation-mode is introduced to the scientific community and business world.

Methods/Approach

As part of a design science research, an artefact, i.e. an add-on for speech-interaction in business software, was developed and evaluated using a survey among ERP users and researchers.

Results

In the area of IPA-features, the search-function and speech input for textual fields were recognised as most useful. The newly introduced feature, the explanation mode, was positively received too. There is no significant correlation between the usefulness of features and participant-characteristics, affinity to technology or previous experience with IPAs in a private context, which is in line with previous studies in the private environment leading to the conclusion that the task attraction is the most important element for usefulness.

Conclusions

Most of the participants agreed that the speech-input is not able to fully substitute standard input devices, such as a keyboard or a mouse, so the IPA is recognised as an addition to traditional input methods. The usefulness is rated high especially for speech-input for long text fields, calling up masks and search-functions.

IoT and Smart Home Data Breach Risks from the Perspective of Data Protection and Information Security Law

Publié en ligne: 03 Dec 2020
Pages: 167 - 185

Résumé

Abstract Background

IoT and smart devices have become extremely popular in the last few years. With their capabilities to collect data, it is reasonable to have concerns about the protection of users’ personal information and privacy in general.

Objectives

Comparing existing regulations on data protection and information security rules with the new capabilities provided by IoT and smart devices.

Methods/approach

This paper will analyse information on data collected by IoT and smart devices and the corresponding legal framework to explore whether the legal framework also covers these new devices and their functionalities.

Results

Various IoT and smart devices pose a high risk to an individual's privacy. The General Data Protection Regulation, although a relatively recent law, may not adequately regulate all instances and uses of this technology. Also, due to inadequate technological protection, abuse of such devices by unauthorized persons is possible and even likely.

Conclusions

The number of IoT and smart devices is rapidly increasing. The number of IoT and smart home device security incidents is on the rise. The regulatory framework to ensure data controller and processor compliance needs to be improved in order to create a safer environment for new innovative IoT services and products without jeopardizing the rights and freedoms of data subjects. Also, it is important to increase awareness of homeowners about potential security threats when using IoT and smart devices and services.
