This paper aims to explore a possible relationship between democracy and the environment, more specifically between freedom and environmental sustainability (environmental performance). The conceptual lenses of the Quadruple and Quintuple Innovation Helix Frameworks were used as they emphasize the importance of democracy and ecology (environmental sustainability) for knowledge and innovation and vice versa. The empirical model focused on the following research question: What is the correlation between political freedom and environmental performance? In essence, all countries in the world with a population of one million or more were included (a total of 156 countries), and the reference year was 2016. The empirical outcome of the correlation analysis was a positive Pearson correlation of about 0.56 (or 0.73 if we examine regional country groups), and, perhaps even more significantly, this correlation was significant at the 0.001 level (two-tailed). The correlation results lend themselves to the following interpretation: The higher the political freedom in a country, the more likely it is to have a higher environmental performance. Similarly, the lower the political freedom in a country, the more likely it is to have a lower environmental performance. As a preliminary proposition, therefore, democracy, environmental sustainability, and innovation-driven knowledge economies may have a highly symbiotic and synergistic dynamic and non-linear relationship.

Improving energy efficiency in buildings is a major priority and challenge worldwide. The employed measures vary in nature, and the decision analyst, who is typically the architect, the engineer, or the building expert that has undertaken the task to suggest energy efficient solutions, faces a complex decision problem comprising numerous decision variables and multiple, usually competitive objectives. The solution of such multi-objective problems typically involves some sort of objectives aggregation, which reflects the preferences of the involved final decision maker that is the building’s user, occupant, and/or owner. The preferences elicitation, however, is a difficult task, and this paper aims to provide an interactive framework that will allow their consideration in a relatively easy manner. More specifically, a mathematical programming approach is proposed herein, which allows the elicitation and incorporation of the decision maker’s preferences in the decision model via the assessment of his/her utility function with the assistance of the multicriteria decision aid method UTASTAR. To study the feasibility and efficiency of the proposed approach, the case of a simple building is examined as an application example. The study results suggest that the proposed approach is capable of helping the decision analyst to suggest energy measures that satisfy, as much as possible, the decision maker’s preferences, without having to precisely prescribe them beforehand.

The risk of bankruptcy is naturally faced by all corporate organizations, and there are various factors that may lead an organization to bankruptcy, including microeconomic and macroeconomic ones. Many researchers have studied the prediction of business bankruptcy risk in recent decades. However, the research on better tools continues to evolve, utilizing new methodologies from various scientific fields of management science and computer science. This chapter deals with the development of statistical and artificial intelligence methodologies for predicting failures for small and medium-sized enterprises, considering financial and macroeconomic data. Empirical results are presented for a large sample of European firms.

Customer satisfaction measurement is an important and critical issue of all businesses in the tourism sector, since it gives a better understanding of the needs and requirements of tourists. The Kano model is one of the most widely used approaches in analyzing customer satisfaction, aiming to categorize the quality attributes of products/services in different quality dimensions. The main aim of this chapter is to analyze customer satisfaction from an agro-tourism farm and prioritize potential improvement actions. The preliminary analysis has identified a large set of customer satisfaction criteria that refer to the location, the personnel, the activities, the cost, and the “green” aspects of the agro-tourism farm. The MUSA method has been applied in the context of Kano's theory of attractive quality. The main results show which satisfaction criteria mostly affect satisfaction and/or dissatisfaction, identifying the strong and the weak points of the farm. Finally, combining the previous results, it is possible to prioritize improvement actions.

From its origin at the Renaissance, the art market is part of the global economy. Arts and cultural production add significant real values on the Gross Domestic Product (GDP) of several countries and a strong symbolic contribution in prestige for owners, either private collectors or cities and countries. The significant price fluctuations that may be observed in the market of artistic goods can be explained not only by the uniqueness of works of art and the economic conditions, but also by the changing preferences of buyers. The main aim of this paper is to develop an ordinal regression analysis model for studying the preferences of artistic goods buyers. The applied approach assumes that the price of a work of art depends on a set of criteria aiming to infer additive value functions that aggregate these criteria in such a way that these functions are optimally consistent with a given price. The presented study uses a large set of auction data from the Art Deco furniture market and considers several different criteria that may influence buyers’ preferences. These criteria are related to the physical or intangible characteristics of artistic goods. The results are mainly focused on analyzing buyer's preferences (e.g., contribution of several factors to the price of artistic goods), while the ordinal regression model has been applied in different time periods in order to study how preferences evolve over time. Finally, stability analysis has been performed, with the aim of evaluating the robustness of the results.

Total quality management and innovation are two inherently related concepts that appear to have an important role in the performance of agro-food companies. The main aim of this paper is to review and discuss the theoretical and practical linkages between quality management and innovation, focusing on the agro-food industry, which is characterized as a low-tech sector with high demands for quality standards and food safety systems. The presented review identifies and discusses three conceptual frameworks, and the findings indicate the positive effect of quality on innovation and vice versa, while both factors have a positive impact on firms’ performance. However, other internal and external factors may affect both firm’s quality management and innovation activities. Particularly for the agro-food industry, access to current and new markets is a major motive, objective, and outcome of the quality-innovation nexus, revealing the importance of adopting customer-focused culture.

Purpose The purpose of this study is to evaluate the effectiveness of the new service development (NSD) process in tourism. For this reason, factors influencing the process of service innovation in the hospitality sector were explored and correlated with business performance in the hospitality industry through a multicriteria decision analysis approach. Design/methodology/approach An original multicriteria decision analysis approach is applied in order to estimate the efficiency of the NSD process. The approach follows the principles of ordinal regression analysis, using goal programming techniques. Collected data are based on in-depth structured and questionnaire-based interviews of 77 hotel managers in 147 new services in a representative sample of 99 hotels in Greece. Several financial ratios, covering different aspects of business performance, are used in order to evaluate the NSD process for three years after the services innovation had been launched. Findings These findings reveal the importance of financial liquidity and business efficiency for the hotel industry (i.e. the ability of a firm to use available resources in order to achieve specific sales goals). The aforementioned variables can determine how quickly and effectively assets are converted to cash. In general, the findings show the emphasis that should be given to customer needs, as well as to the effective management of a NSD project. Originality/value Findings of this study may support hotel managers to make complex strategic decisions for future development. These findings have suggested that service innovation should be included as a strategic tool to assess differentiation effort in the hotel industry.

The assessment of sustainability is of the utmost importance nowadays. Several approaches exist that measure sustainability at a national level and rank countries accordingly. Comparison of countries could be done numerically or pictorially. This paper introduces a novel clustering disjoint HJ-biplot approach, which is then applied to data from two well-known models: Sustainability Assessment by Fuzzy Evaluation (SAFE) and the United Nations Sustainable Development Goals Index (UN-SDGs). This approach performs a graphical ranking that makes the sustainability standing of countries very transparent. As expected, the pictorial model yielded similar rankings to those of SAFE and UN-SDGs, but it additionally grouped countries according to their most important indicators, thereby yielding a more global picture of sustainability. Our approach thus comprises a useful complement to existing mathematical sustainability ranking models.

This paper presents data that investigates the creative industries ventures’ performance affected by four different types of networking, namely the social, the professional, the family, and that with public sector organizations. Three hundred and seventy-one questionnaires have been collected for the assessment of networking impact on venture performance. In order to examine the ventures’ performance levels of the female entrepreneurs or self-employed in the creative industries of Greece, we use a multiple criteria method. Based on the data analysis, the most important criterion for the female entrepreneurs in the creative industries to perform highly is professional networking while the least important is observed in the criterion of family networking.

Social innovation is related to new products, services, and models aiming to improve human well-being and create social relationships and collaborations. The business model innovation (BMI) context can foster social innovation and can be applied in social innovation projects and initiatives. What is important for social BMI is the social mission, which needs to be defined in order to be able to move forward with the strategy, the value proposition, and the best practices of the business. Based on the existing social innovation literature and case studies, this paper proposes an “ecosystem” approach that can provide an integrated framework for social business models. This approach adopts the quadruple/quintuple helix innovation models which are able to promote social innovation, enabling a locus-centric and triple-bottom-line-centric entrepreneurial process of knowledge discovery and exploitation. Such a framework may help to study the role, nature, and dynamics of social co-opetitive fractal ecosystems, given emphasis on civil society, political structures, environment, and sustainability. In addition, the social innovation case studies presented in this paper highlight that targeted open innovation is a key element for social BMI.

Success in the hotel industry depends heavily on customer satisfaction, which is highly affected by the quality of service provided by a satisfied workforce. Luxury summer resorts represent an interesting setting for investigating job satisfaction (JS). Hotels in this end of the market face higher customer quality expectations and depend heavily, in order to fulfill these expectations, on a diversified force of seasonal employees. To investigate the key factors that drive overall JS of seasonal employees in summer luxury resorts a survey was conducted in a single setting. The Minnesota Satisfaction Questionnaire was combined with the MUlticriteria Satisfaction Analysis (MUSA), demonstrating that MUSA can be an effective decision making tool also in the area of human resource management. Principal component and confirmatory factor analyses revealed a four-factor structure of the MSQ construct: Empowerment, Task enrichment, HRM policies and Leadership qualities. Moreover, MUSA indicated that Empowerment was the critical factor of JS of seasonal employees.

Organizational ambidexterity balances exploitative and exploratory behaviors so that organizations are able to exploit their existing competencies while simultaneously exploring new opportunities. Similarly, ambidextrous cybersecurity (AMBI-CYBER) focuses on the protection of data, systems, and networks, while fostering the rapid introduction of new technologies within a company. This balance is linked to cybersecurity absorptive capacity and defines the “Cybersecurity Efficient Frontier.” In this paper, we view AMBI-CYBER as a combination of organizational as well as technological and cultural competences which rely upon a multifaceted, multimodal, multinodal, and multilevel set of skills and capabilities. We outline the anatomy of the AMBI-CYBER architecture adopting a balanced scorecard, multistage approach under a 7Ps stage gate model (Patient, Persistent, Persevering, Proactive, Predictive, Preventive, and Preemptive). Such an approach emphasizes the need to enable a complex, nonlinear, adaptive process of dynamic intangible organizational assets, resources, and capabilities across a performance frontier where we aim to optimize safety, security, and privacy effectiveness and efficiency. We also suggests that the Quadruple/Quintuple Helix Innovation model may promote AMBI-CYBER enabling a locus-centric and triple-bottom-line-centric entrepreneurial process of discovery followed by development, exploration, exploitation, and deployment.

The selection and evaluation of suppliers is a very sensitive and crucial process for all companies and organizations, since the quality of the overall supplier management system may affect the quality of the final product. Suppliers nowadays are considered as partners of any business organization having mutual trust as the core of the relationship with them. In contrast to traditional approaches for selecting/evaluating a supplier, which are mainly based on cost, neglecting other important factors, new research efforts have highlighted the importance of multicriteria decision analysis in this problem. The aim of this paper is to propose an integrated framework for supplier selection and evaluation giving emphasis on the dynamic nature of the problem. The proposed framework is based on the UTA-II method, which is a preference disaggregation approach from the field of multicriteria decision analysis, and its applicability is demonstrated through a real-world application in a food company. The major results of the case study show the importance of quality, cost, delivery, and collaboration in the relationship between companies and suppliers.

The evaluation of environmental practices of each country is a very interesting area which has recently gained significant attention. An analysis, which can provide results for comparisons among countries with different economies, is data envelopment analysis. In this chapter, countries’ environmental efficiency is estimated using data envelopment analysis. Applying a slack-based model under the consideration of constant returns to scale and variable returns to scale technologies, a composite index is calculated from the efficiency scores of each model. These models consider both desirable and undesirable outputs. However, especially for undesirable outputs, the data collected are not accurate and could potentially be subject to uncertainty. To handle the uncertainty in the undesirable data, a chance-constraint DEA model is applied. Results of the deterministic model show that Australia gathers high values of environmental efficiency. However, in the presence of noise in the undesirable data, the rankings of the countries change.

The dynamic presence and intensification of tourism has created several negative environmental impacts and have made it one of the industries with the widest range of environmental pressures, calling for a more sustainable course in the future. In this article, in order to respond to the increasing level of environmental concerns of tourists, as well as to the new economic environment, several initiatives as well as environmental management systems (EMSs) are developed for tourism enterprises. EMS applications offer several benefits to the committed organizations, however, the lack of resources and knowledge often poses difficulties in developing and sustaining international EMS. The tourism industry includes two main activities: housing and transportation. The present article concerns housing and its impact on the environment. It also addresses the factors that influence corporate environmental management by identifying the motives and benefits, as well as the difficulties in improving the environmental performance of hotels.
