The problem of waste reduction is particularly emphasized the sources of environmental income i.e. tax and unit-pricing, instead of stimulus recycling administrative in the published literatures. A long-term rebate policy for recycling fund allowance was implemented in different metropolitan districts. However, evaluating the recycling performance at the local level does not include examining its rationality and efficiency in detail. To understand the uncertainty of role in decision making for substitute ranking, analysis based on decision making using fuzzy interval for performance assessment. This article redefines the criteria for evaluating recycling performance at the township level with assistance of artificial intelligence, and illustrates the results. We used a simple and swift evaluation process, namely, the VIKOR method, in place of the traditional public hearing or the Delphi method. The conclusion derived from the results can be used to analyze the effectiveness of the rebate policy for recycling at the township level.

Using artificial intelligence (AI) technology to replace human decision-making will inevitably create new risks whose consequences are unforeseeable. This naturally leads to calls for regulation, but I argue that it is too early to attempt a general system of AI regulation. Instead, we should work incrementally within the existing legal and regulatory schemes which allocate responsibility, and therefore liability, to persons. Where AI clearly creates risks which current law and regulation cannot deal with adequately, then new regulation will be needed. But in most cases, the current system can work effectively if the producers of AI technology can provide sufficient transparency in explaining how AI decisions are made. Transparency ex post can often be achieved through retrospective analysis of the technology's operations, and will be sufficient if the main goal is to compensate victims of incorrect decisions. Ex ante transparency is more challenging, and can limit the use of some AI technologies such as neural networks. It should only be demanded by regulation where the AI presents risks to fundamental rights, or where society needs reassuring that the technology can safely be used. Masterly inactivity in regulation is likely to achieve a better long-term solution than a rush to regulate in ignorance.

IntroductionStroke is a major contributor to mortality, disability and long-term use of healthcare services. As for all chrono-dependant conditions, clinical results are associated with timely access to appropriate care. Thrombectomy (EVT) is an effective treatment for large vessel occlusions, but can only be provided in highly-specialized centers by experienced personnel. We sought to develop a framework to aid decision-making on the appropriateness of opening new EVT centers in Québec, Canada.MethodsData sources included provincial administrative healthcare databases, population density statistics, field evaluation of Québec's four existing EVT care networks, and literature review concerning structural and performance criteria for EVT centers. We consulted EVT clinical teams, interdisciplinary stroke experts, patients, professional association representatives, healthcare managers and decision-makers.ResultsAccess to EVT is suboptimal in all 17 regions of Québec, with virtually no access in remote areas. Results of key performance indicators indicated favorable treatment delays after arrival at the EVT center. However, door-to-needle and door-in-door-out times were long for patients transferred from non-EVT centers. High use of ambulances indicated the potential to transport patients to the most appropriate center. In light of ‘real world’ results and other sources of information, the need for a new EVT center should consider the following criteria: sub-optimal EVT access within the region; transport time to an existing EVT center >1 hour; expected patient volume within 2 hours of transport; impact on volume of existing programs; availability of long-term financial support; availability of a critical mass of neurointerventionists, vascular neurologists, and neurosurgeons; demonstrated quality of stroke care; and, presence of a stroke unit.ConclusionsThe triangulation of literature, clinician experience and the Québec context enriched the evaluation process. Furthermore, this facilitated the development of a framework that was broadly applicable across regions to the real-world setting of decision-making in a complex system of care.

AbstractBackground and Objectives:Hospital-acquired legionnaires' disease can be prevented by disinfection of hospital water systems. This study assessed the long-term efficacy of copper-silver ionization as a disinfection method in controllingLegionellain hospital water systems and reducing the incidence of hospital-acquired legionnaires' disease. A standardized, evidence-based approach to assist hospitals with decision making concerning the possible purchase of a disinfection system is presented.Design:The first 16 hospitals to install copper-silver ionization systems forLegionelladisinfection were surveyed. Surveys conducted in 1995 and 2000 documented the experiences of the hospitals with maintenance of the system, contamination of water withLegionella, and occurrence of hospital-acquired legionnaires' disease. All were acute care hospitals with a mean of 435 beds.Results:All 16 hospitals reported cases of hospital-acquired legionnaires' disease prior to installing the copper-silver ionization system. Seventy-five percent had previously attempted other disinfection methods including superheat and flush, ultraviolet light, and hyperchlorination. By 2000, the ionization systems had been operational from 5 to 11 years. Prior to installation, 47% of the hospitals reported that more than 30% of distal water sites yieldedLegionella. In 1995, after installation, 50% of the hospitals reported 0% positivity, and 43% still reported 0% in 2000. Moreover, no cases of hospital-acquired legionnaires' disease have occurred in any hospital since 1995.Conclusions:This study represents the final step in a proposed 4-step evaluation process of disinfection systems that includes (1) demonstrated efficacy ofLegionellaeradication in vitro using laboratory assays, (2) anecdotal experiences in preventing legionnaires' disease in individual hospitals, (3) controlled studies in individual hospitals, and (4) validation in confirmatory reports from multiple hospitals during a prolonged time (5 to 11 years in this study). Copper-silver ionization is now the only disinfection modality to have fulfilled all four evaluation criteria.

Today, companies can no longer assume that the past will be a good predictor of the future; Those that fail to prepare for radically new possibilities may face sudden irrelevance. Strategic Foresight, aka, Futures thinking, provides a structured approach enabling people and organizations to overcome cognitive biases and think more realistically about change. It helps to uncover blind spots, imagine radically different futures, and improve decision-making. Climate disruption, artificial intelligence, and automation are quickly transforming the landscape for business and sustainability. This chapter will review the Strategic Foresight tools used to embed long-term strategic thinking and planning concerning policy and strategy.

Introduction: Coercion is frequent in clinical practice, particularly in psychiatry. Since it overrides some fundamental rights of patients (notably their liberty of movement and decision-making), adequate use of coercion requires legal and ethical justifications. In this article, we map out the ethical elements used in the literature to justify or reject the use of coercive measures limiting freedom of movement (seclusion, restraint, involuntary hospitalization) and highlight some important issues.Methods: We conducted a narrative review of the literature by searching the PubMed, Embase, PsycINFO, Google Scholar and Cairn.info databases with the keywords “coercive/compulsory measures/care/treatment, coercion, seclusion, restraint, mental health, psychiatry, involuntary/compulsory hospitalization/admission, ethics, legitimacy.” We collected all ethically relevant elements used in the author's justifications for or against coercive measures limiting freedom of movement (e.g., values, rights, practical considerations, relevant feelings, expected attitudes, risks of side effects), and coded, and ordered them into categories.Results: Some reasons provided in the literature are presented as justifying an absolute prohibition on coercion; they rely on the view that some fundamental rights, such as autonomy, are non-negotiable. Most ethically relevant elements, however, can be used in a balanced weighting of reasons to favor or reject coercive measures in certain circumstances. Professionals mostly agree that coercion is only legitimate in exceptional circumstances, when the infringement of some values (e.g., freedom of movement, short-term autonomy) is the only means to fulfill other, more important values and goals (e.g., patient's safety, the long-term rebuilding of patient's identity and autonomy). The results of evaluations vary according to which moral elements are prioritized over others. Moreover, we found numerous considerations (e.g., conditions, procedural values) for how to ensure that clinicians apply fair decision-making procedures related to coercion. Based on this analysis, we highlight vital topics that need further development.Conclusion: Before using coercive measures limiting freedom of movement, clinicians should consider and weigh all ethically pertinent elements in the situation and actively search for alternatives that are more respectful of patient's well-being and rights. Coercive measures decided upon after a transparent, carefully balanced evaluation process are more likely to be adequate, understood, and accepted by patients and caregivers.

The decision of tender evaluation and allotment is one of the important step of any construction project. There has been a trend away in tender evaluation process from considering quantitative parameters ("lowest price win", "maximum benefit win") to other qualitative parameters (past performance, time of completion). This paper reviewed past and recent literature in order to identify the current tendering process and the various techniques that have been applied previously. The study utilized different MCDM techniques for evaluation of tendering process. Multi-criteria decision making research has become one of the main areas of research for dealing complex and critical decision problems. This paper outlines the use of various systematic decision making tool for the tender selection. Qualitative and quantitative criteria are compared, and the uncertainty associated with the selection of right contractor is highly reduced. By using a case study the tender evaluation is fully investigated applying various MCDM techniques. Results from the different methods are compared and fuzzy extend analysis, fuzzy TOPSIS showed slight difference in results from the other methods.

Decision-making to determine the working units for being prioritized to be developed in order to improve fishery monitoring in WPP-711 is imperative. The Ministry of Maritime Affairs and Fisheries should make no mismatch decision-making through long-term calculation and analysis. The problem of determining the priority of working units is a complex problem, thus it is required to find an appropriate method to avoid a missmatch decision. TOPSIS is a decision-making method capable of solving multi-criteria problems. TOPSIS working principle determines the alternative by considering the shortest distance from the positive ideal alternative and furthest from the ideal negative solution. To improve the performance of TOPSIS, this research is integrated with Fuzzy logic with the aim of giving the right numeric value preference. From the test of 11 alternatives of 6 criteria, the priority of development of fishery monitoring in FMA 711 is: Pontianak Working Unit= 0.917, Batam Working Unit = 0.791 Natuna Working Unit = 0.685 and Tanjung Pinang Working Unit = 0.607. Furthermore,  the ranking result will be used as the basis for determining the strategy in increasing the monitoring of WPP-711 to minimize State losses due to the illegal fishing within Indonesia’s WPP-711 Regions.
