The Impact of Human Recreational Activities in Marine Protected Areas: What Lessons Should Be Learnt in the Mediterranean Sea?

2002

. The aesthetic appeal of marine reserves and the facilities provided, together with the increased public awareness of nature, all contribute to creating massive tourism in MPAs. Human activities are being changed inside MPAs in two ways: humans as top predators are generally being removed, but in turn they could come back at great numbers as visitors. Many authors have studied the impact of visitors, and the results highlight that the consequences can be very substantial and may represent a severe threat to the overall diversity of marine communities. To date, the documented effects of human recreational activities on natural communities are restricted to assessing the consequences of tram…

Assessing the sustainability of water companies: A synthetic indicator approach

2016

Performance indicators (PIs) are essential in the benchmarking process used to rate and rank water companies. However, a set of individual PIs does not provide a holistic assessment of company performance from multiple perspectives. A multidimensional evaluation of the performance of water companies can be achieved by aggregating the PIs into a synthetic indicator. Although the concept of sustainability involves economic, environmental and social criteria, most of the previous studies have not considered these three dimensions simultaneously. This paper discusses a process of indicator aggregation using two approaches based on multi-criteria decision analysis to evaluate and compare the sus…

Economic Cooperation Between Latvia and China on the Background of Belt and Road Initiative with Focus on Cargo Potential

2018

Latvia is a Belt and Road Initiative country and can contribute to its Eurasian Land Bridge. The existing railway infrastructure can be used for establishing the Eurasian Land Bridge Northern Branch via Latvia, but the problem is a lack of cargo for this route. It can be integrated into the existing Eurasian Land Bridge with specialization to connect China and some European countries—the Scandinavian countries. The aim of the study is to assess the potential volume of Latvian cargo for the Eurasian Land Bridge Northern Branch through Latvia. The methods of the study are statistical analyses and the forecasts of experts. Forecast of experts is an innovative method for investigating this top…

Combinatorial Double Auction Radio Resource Allocation Model in Crowd Networks

2018

International audience; Industrial Partners (IPs) with Mobile Network Operators (MNOs) are extending the mobile network infrastructure with Small Cells (SCs) in order to meet the growing mobile traffic demand. Due to the increasing number of telecommunication market competitors and the scarcity of radio resources, static sharing schemes are no more efficient. New dynamic schemes should be considered to meet both user expectations and economic success. In a crowd networking context, we propose in this work a dynamic radio resource scheme based on combinatorial double auctions. The participants in these auctions are the MNOs considered as buyers and the IPs, providers of SCs, considered as se…

Tariffs and efficient performance by water suppliers: an empirical approach

2012

Water leaks are an environmental and sustainable issue as well as an economic issue. The objective of this paper is to analyse the efficiency of a sample of Spanish urban water systems by considering water leaks in a network as undesirable outputs. Data envelopment analysis (DEA), an analytical benchmarking methodology, is used to calculate technical and economic efficiency. We also discuss the possible relationship between efficiency and tariffs charged to users. Results show that the possibilities for reducing water leaks in networks are high, thus demonstrating that there is room for savings from an economic and environmental point of view. The assessment of efficiency performance could …

The institutional pillars of management accounting function

2009

PurposeThe purpose of this paper is to theorize the institutional pillars of management accounting function.Design/methodology/approachThe paper adopts a comparative case study approach.FindingsInstitutional pillars of management accounting are explored on the basis of two longitudinal case studies. Competitive/economic forces and three analytical elements of institutional theory are composing institutions: regulative, normative and cultural‐cognitive pillars. Each element is important, and all of them may work in combination, but they operate through distinctive mechanisms and processes. This paper illustrates how they provide the basis for compliance, order and the legitimacy of not the w…

The national cancer programme in Romania: Challenges in a low-resource healthcare system

2017

Abstract The incidence and mortality due to malignancies are increasing in Romania. Since 2001, Romania provides the public support for cancer patients through the National Programme for Cancer (NPC). Using documentary analysis, the present paper provides a longitudinal and comprehensive examination of all the policy documents issued during 2001 and 2016 within the programme, and of the five implementation reports available. The paper examines several press articles as a sole source for exploring implementation difficulties. Results show that current cancer policies in Romania are focusing on treatment and screening, less on prevention, surveillance, research and rehabilitation and not at a…

Conservation of forest biodiversity using temporal conservation contracts

2012

Abstract Temporal conservation contracts are used to protect biodiversity in privately owned lands worldwide. We examine how stand characteristics and habitat requirements of target species affect the contract length in a boreal forest context. We develop an integrated optimization model and apply the model with data on endangered species occurring in spruce forests in Finland. The results suggest that a cost-effective conservation policy for protecting privately owned forest land involves both short- and long-term contracts between landowners and environmental agencies. The higher the conservation objective, the more intensively long-term contracts should be assigned. Managed stands should…
