Multi-criteria evaluation of medical waste management process under intuitionistic fuzzy environment: A case study on hospitals in Turkey

Waste management has come to the fore in the whole world with the increasing impact of the Covid-19 pandemic along with concerns about human health, environmental threats, and socio-economic factors, etc. Medical waste is one of the waste types that need special management processes including particularly collection, storage, separation, and disposal. Healthcare activities create a great amount of medical waste deriving from the hospitals. This study aims to determine the hospital that carries out medical waste management in the most effective way in Erzurum, Turkey. To handle intense uncertainty in the evaluation process, the case is analyzed by Intuitionistic Fuzzy Multi-Criteria Decision-Making (IFMCDM) methods. The present study contributes to the literature by focusing on a real case problem under IF environment in a Group Decision-Making (GDM) framework. Additionally, based on the literature review and expert judgments, the evaluation criteria relevant to the case are defined in this paper. To this end, a four-phased integrated methodology that involves Intuitionistic Fuzzy Weighted Averaging (IFWA), IF Analytical Hierarchy Process (IFAHP), IF Technique for Order Preference by Similarity to Ideal Solution (IFTOPSIS) and One-Dimensional Sensitivity Analysis, is conducted. Firstly, IFWA is aimed to express the significance levels of decision makers (DMs) based on their knowledge, qualifications and experiences. Secondly, IFAHP is used to calculate the importance weights of the decision criteria and IFTOPSIS is preferred to rank the available hospitals. Then, sensitivity analysis is employed to display robustness. According to the results, the most important criteria are Qualified personnel, Health institution infrastructure, and Control of waste, respectively and the most efficient hospital is determined.     

The effect of ownership on sustainable development and environmental policy in urban waste management: An explicatory empirical analysis of Italian municipal corporations

This paper investigates the effect of ownership on sustainable development and environmental policy in Italian municipally owned corporations (MOCs) dealing with urban waste management, trying to understand if multiple ownership can generate better performance compared to single ownership and if the presence of private partners could be crucial in this. The research question is answered by analyzing 41 MOCs of the largest Italian cities operating in urban waste management. In this specific sector, public administrations have tried to improve their offer in terms of sustainable development, environmental policy, and efficiency. The paper covers the Italian case study, where urban waste production per capita is higher than the European average figure. The waste cycle management service is operated in Italy at local level through totally publicly owned companies (monoadministration or multiadministration), mixed (public–private) companies, or via a full externalization achieved by means of public tenders. Through a multinomial ordered probit panel, we show that MOCs with multiple owners perform better than those having a single owner and perform much better with the presence of a private partner, confirming those academic findings according to which collaborative arrangements can increase efficiency, do better than public sector bureaucracy, and lower the costs of service provision. The results of this paper can be used by academics, practitioners, and policy makers alike. To the best of our knowledge, this is the only study that applies this perspective to the analysis of the current international waste management scenario with relation to MOCs having multiple ownerships.

Sustainable tourism in Greek islands: the integration of activity‐based environmental management with a destination environmental scorecard based on the adaptive resource management paradigm

Tourism is a major industry that can lead to economic gains as well as to degraded environment and social infrastructure. Tourism has the potential to destroy the available common environmental resources through overuse and poor management practices, as limited information disclosure and poor monitoring of actions encourage the perpetuation and extension of environmental problems. Based on the adaptive resource management paradigm for addressing problems related to the use of the commons, this paper suggests a methodology for the development of a management tool that can provide island hotels with a continuous flow of timely, relevant, accurate and objective information on the environmental impact of critical corporate activities. The tool, named the destination environmental scorecard (DES), draws on activity‐based management concepts and can help local hotel SMEs measure and compare their performance against certain standards and thus conduct operations in a responsible and measurable way to the benefit of both business financial performance and regional sustainability. The paper presents the DES operational characteristics and the potential benefits from its implementation. Copyright © 2008 John Wiley & Sons, Ltd and ERP Environment.     

Understanding variation in the relationship between environmental management practices and firm performance across studies: A meta‐analytic review

The relationship between environmental management practices and firm performance has continuously received much attention in academic research. As existing literature on the link of the two constructs is characterized by heterogeneous research characteristics and mixed empirical evidence, one interesting question arises: Do research characteristics affect the magnitude and direction of the relationship between environmental management practices and firm performance? Amassing a database of 92 studies, 199 effect sizes, and 72,258 firms, we examine this question by conducting a meta‐analysis. The characteristics investigated in this study include item number of performance measures, year of data collection, industry type, economic development, and Hofstede's five cultural dimensions. A meta‐regression reveals that environmental management practices are positively associated with firm performance and that the degree of this association depends on these contexts. Specifically, the environmental management practices–performance relationship increases with year of data collection, is stronger with multiple item measures, and is higher for firms in developed countries and in cultures characterized by high power distance, low individualism, low uncertainty avoidance, and low long‐term orientation.     

The development and application of a process model for R&D project management in a high tech firm: A field study

In R&;D organizations of high tech firms, multiple R&;D projects are executed concurrently and timeliness of project completion - i.e., developing the right products at the right times - is a matter of serious concern. Given that the priority of R&;D projects and the interdependencies between the projects in a high tech firm change dynamically, high tech R&;D project management is a complex and challenging endeavor. To improve the understanding and management of high tech R&;D projects, this paper reports the findings of a field study where we, first, develop and empirically estimate a model that relates project priority over time with the generative mechanisms of market pull and technical challenge associated with R&;D projects. Next, we develop and demonstrate the application of a process model within which the time-varying project priority model is embedded. The process model makes it possible to allocate fixed resources among competing projects with time-varying interdependencies, thereby improving the timeliness of project completion. This research was conducted in collaboration with a major U.S. high tech firm. The corporate R&;D center of the firm served as the research setting for the field study. We present an application of the process model to delineate the evolution of the R&;D organization with the merger of its (technology driven) parent firm with another (market driven) high tech manufacturing firm. The application of the process model generates theoretical insights that are used to develop testable propositions. Implications of the study findings and directions for future research are discussed.
