Assessment of wastewater treatment plant design for small communities: Environmental and economic aspects
2012
The preliminary design and economic assessment of small wastewater treatment plants (less than 2000 population equivalent) are issues of particular interest since wastewaters from most of these agglomerations are not covered yet. This work aims to assess nine different technologies set-up for the secondary treatment in such type of facilities embracing both economic and environmental parameters. The main novelty of this work is the combination of an innovative environmental decision support system (EDSS) with a pioneer approach based on the inclusion of the environmental benefits derived from wastewater treatment. The integration of methodologies based on cost-benefit analysis tools with th…
Evaluating Infrastructure Alternatives for Regional Water Supply Systems by Model-assisted Cost-benefit Analysis – A Case Study from Apulia, Italy
2014
The main challenge associated to regional water supply systems planning lies in understanding the best infrastructure alternatives to improve service given a certain configuration of the resources system. While cost-effectiveness assessments are still widespread in this type of analyses, they do not account for the fact that, especially in mature systems, service improvements tend to follow the law of marginal diminishing returns, so that a cost – benefit assessment should be preferable. Both costs and benefits can be organized into a cost-benefit analysis (CBA) framework. In a complex system, a model reproducing its topology and characteristics better describes the impacts of the alternati…
Social return on investment (SROI), including elements on cost-benefit Analysis
2017
The chapter deals with the theme of social return on investments (SROI), including general elements of cost–benefit analysis (CBA). In addition, some major appraisal tools for public projects are discussed. SROI is a method that aims to measure social outputs, and value of social outcomes in monetary terms (Boyd, 2004). The basic assump- tion underlying the SROI technique is that all economic organizations (whether private or public) have an impact on people, society and the environment. Thus, the technique is always underpinned by an underlying model or conception of society. Such an impact can be strictly economic, social, and/or environmental, respectively. By economic we mean all that h…

Starpfunkcionālu komandu veidošana biznesa organizācijās
2019
Šajā pētījumā galvenā uzmanība pievērsta savstarpēji funkcionējošu komandu izveidošanai mazos uzņēmumos un to analīzei, izmantojot izmaksu un ieguvumu analīzi. Turklāt pētījums ir arī vērsts uz problēmu noteikšanu sākotnējā posmā. Caur pētījumiem un precīzu datu analīzi bija noskaidrota nepieciešamība starpfunkcionālu komanu veidošanai. Pamatojoties uz pierādījumiem, kuri ir sniegti pēc visu pētījumu procedūru pabeigšanas, uzņēmums var pieņemt lēmumu. Šī pētījuma rezultāti atklāj vairākus faktorus, kas būtiski ietekmēja darbiniekus, kuri strādā dažādās struktūrvienībās: spēju efektīvi sazināties un dibināt ciešas attiecības ar citiem, lai sasniegtu kopējo mērķi. Pirmajā nodaļā ir aplūkota s…
Topical Fluoride for Preventing Dental Caries in Children and Adolescents
2012
The use of topically applied fluoride has been widely researched as a means to reduce the risk of dental caries in conjunction with other treatment modalities (mechanical oral hygiene, dietary control, antimicrobial intervention, pit and fissure sealants). There is overwhelming evidence that reports not only the significance and importance of the use of fluoride as a caries-preventive agent, but also how safe fluoride application is when used appropriately, particularly in higher risk individuals and populations. This paper reviews the caries-protective benefits of topical fluoride application in children and adolescents, with an emphasis on the clinical efficacy and safety of the vehicles …
Financial Aspects of Cervical Disc Arthroplasty: A Narrative Review of Recent Literature
2020
Recently, there has been significant interest in understanding the cost-effectiveness of treatments in spine surgery as health care systems in the United States move toward value-based care and alternative payment models. Previous studies have shown comparable outcomes of cervical disc arthroplasty (CDA) and anterior cervical discectomy fusion; however, there is a lack of consensus on the cost-effectiveness of CDA to support full adoption. Evidence of the limitations of these cost-analysis studies also exists in the literature, including industry funding, potential selection bias, and varying methods of calculating value. The goal of this narrative review is to provide an overview of the co…
Disease dispersion as a spatial interaction: The case of Flavescence Dorée
2020
International audience; Flavescence dorée is a serious and incurable vine disease transmitted by an insect vector. Focusing on its spatial diffusion and on its control with pesticides, this paper investigates the private strategies of wine producers and their socially optimal counterparts. The socially optimal regulation has to address two externalities regarding private treatment decisions: (a) the insufficient consideration of collective benefits from controlling the vector populations; (b) the failure to take into account environmental damage related to pesticide application. The probability of infection is estimated on French data from a spatial econometric specification. Three alternat…
A cost efficiency analysis of flood proofing measures for hydraulic risk mitigation in an Urbanized riverine area
2020
Non-structural measures for flood risk mitigation are often more economically accessible, easier to implement, and are highly effective, especially in view of the pursuit of risk resilience objectives. Among the non-structural measures, more importance is increasingly being attributed to flood proofing interventions. There are two main types of flood proofing: dry proofing and wet proofing. An example of dry proofing is shielding, which involves the use of flood barriers that can be installed in the entrances of buildings or outside the buildings in order to avoid contact with the houses and deviate the water flow. Their use must be supported by a detailed hydraulic analysis to ensure the c…
Modeling cost-effectiveness and health gains of a âuniversalâ versus âprioritizedâ hepatitis C virus treatment policy in a real-life cohort
2017
We evaluated the cost-effectiveness of two alternative direct-acting antiviral (DAA) treatment policies in a real-life cohort of hepatitis C virusâinfected patients: policy 1, âuniversal,â treat all patients, regardless of fibrosis stage; policy 2, treat only âprioritizedâ patients, delay treatment of the remaining patients until reaching stage F3. A liver disease progression Markov model, which used a lifetime horizon and health care system perspective, was applied to the PITER cohort (representative of Italian hepatitis C virusâinfected patients in care). Specifically, 8,125 patients naive to DAA treatment, without clinical, sociodemographic, or insurance restrictions, were us…
