Sustainable consumption as a complex phenomenon at the boundaries of different (ecological, economic, social) systems requires theoretical approaches that do justice to its complex causality and dynamism. Participatory systems mapping offers a tool to achieve this purpose. Its policy relevance lies in its ability to include diverse views, multiple actors, and offer options for policy intervention. The research reported here applied participatory systems mapping in order to define and identify system boundaries for sustainable consumption and uncover perceived causal relationships among the determining factors of sustainable consumption. By revealing the mental models of an expert and a conscious consumer panel on sustainable consumption in general, we can shed light on the cognitive constructions of sustainable consumption and identify most important boundaries that were chosen and their implications on policy-making. The expert panel framed the boundaries as lack of sustainable consumption, while the conscious consumer panel employed a positive framing as strong communities in sustainable consumption. The two panels also differed in their focus on scale: Experts targeted the national scale, while conscious consumers concentrated at the local scale. 相似文献
Studied for decades in disciplines such as ecology, psychology, engineering and sociology ‘resilience’ can be defined as a system's ability to withstand and respond to change. The tourism literature has embraced the concept of community resilience by harnessing concepts of adaptive capacity and vulnerability. Many of these studies have focused on the tourism system's ability to respond to short-term disasters and hazards. With the growth of resilience studies in tourism, it is timely to take stock of the core premise of resilience as it is applied to tourism and to identify key gaps in current research. Consequently, this research aims to identify the core concepts of community resilience, with a focus on its application within tourism. The findings reveal that many studies have been conceptual, although there are an increasing number of empirical studies underpinned by resilience theory. Therefore, a conceptual model is presented to broaden existing resilience research and to guide future research into community resilience to tourism decline and rejuvenation. 相似文献
We analyze the impact of post-trade anonymity on liquidity and informed trading in an order driven stock market. The German
stock market introduced the Central Counterparty (CCP) in March 2003 for German equities traded on its anonymous electronic
trading platform Xetra leading to a major change in its existing transparency regime. Before the introduction trader IDs were
revealed to the counterparties of a trade, with the introduction of the CCP even after the transaction the traders remain
anonymous. Previous theoretical and empirical research documents that pre-trade anonymity results in increased liquidity,
while results on post-trade anonymity are mixed. We find a significant increase in liquidity measured through a reduction
of 25% in implicit transaction costs. We also document that the arrival rate of informed traders is reduced in the anonymous
setting. Following recent findings of Bloomfield et al. (J Finan Econ 75:165–199, 2005) that informed traders take on the role of liquidity providers we interpret our findings as indication that informed traders
change their behavior in providing liquidity more aggressively in an anonymous environment. 相似文献
Industrial hog farming is an increasingly important land use in Mexico. Despite the known public health and environmental risks associated with this factory-style model of production, hog concentrated animal feeding operations (CAFOs) remain unregulated. Legal standards regarding the establishment and operation of swine CAFOs are lacking at municipal, regional, and federal levels. There are currently no restrictions on the size, concentration, or geographic location of operations, and public notice to surrounding and downstream communities is generally not required. These lax environmental standards facilitate swine CAFO expansion in regions such as the Perote Valley, with potential for negative long-term impacts on public health, community well-being, water resources, ecosystems, and climate. 相似文献
Within four years now, the German Renewable Energy Resources Act (EEG) has been amended in 2016 for the third time. The main point of the current reform is the extension of bidding schemes to determine the remuneration of renewable power generation. The articles analyses whether or not the expected decrease in costs and improvement of deployment control could ever occur, and considers the critique of thwarting the energy transition and jeopardising the diversity of actors involved in the industry. 相似文献
Background: Sarcoidosis is a multi-system inflammatory disorder characterized by the presence of non-caseating granulomas in involved organs. Patients with sarcoidosis have a reduced quality-of-life and are at an increased risk for several comorbidities. Little is known about the direct and indirect cost of sarcoidosis following the initial diagnosis.Aims: To provide an estimate of the healthcare resource utilization (HCRU) and costs borne by commercial payers for sarcoidosis patients in the US.Methods: Patients with a first diagnosis of sarcoidosis between January 1, 1998 and March 31, 2015 (“index date”) were selected from a de-identified privately-insured administrative claims database. Sarcoidosis patients were required to have continuous health plan enrollment 12 months prior to and following their index dates. Propensity-score (1:1) matching of sarcoidosis patients with non-sarcoidosis controls was carried out based on a logistic regression of baseline characteristics. Burden of HCRU and work loss (disability days and medically-related absenteeism) were compared between the matched groups over the 12-month period following the index date (“outcome period”).Results: A total of 7,119 sarcoidosis patients who met the selection criteria were matched with a control. Overall, commercial payers incurred $19,714 in mean total annual healthcare costs per sarcoidosis patient. The principle cost drivers were outpatient visits ($9,050 2015 USD, 46%) and inpatient admissions ($6,398, 32%). Relative to controls, sarcoidosis patients had $5,190 (36%) higher total healthcare costs ($19,714 vs $14,524; p?0.001). Sarcoidosis patients also had significantly more work loss days (15.9 vs 11.3; p?0.001) and work loss costs ($3,288 vs $2,527; p?0.001) than matched controls.

Conclusions: Sarcoidosis imposes a significant economic burden to payers in the first year following diagnosis. 相似文献
This article examines the practices of governance enacted within the framework of the international administration of Kosovo, which was established in 1999. I analyse the complex interplay between power and the liberal-democratic norms around which the UN-led mission defined its role in the province. The international administration exercised significant power in the legal/institutional reconstruction of the province, and in its systematic attempts to socialise Kosovars into accepting Western-based norms of liberal democracy as the only reasonable foundation of their polity. At the same time, however, the norms advocated by the international administration proved to be the source of a certain degree of power for the people of Kosovo. Specifically, those norms provided the framework within which Kosovars were able to criticise the international administration, and to claim the right to greater participation in decisions regarding the province. Over the past couple of years, Kosovo has witnessed the emergence of a shared normative framework within which the international administrators and Kosovar political elites articulate often competitive truth claims about the problems of the province, and mobilise different forms of power in support of those claims. 相似文献
This case study utilizes a value of information decision framework to provide mine managers guidance regarding the purchase of ore grade scanners. LKAB's Kiruna mine produces three types of iron ore to meet long-term contractual agreements on a monthly basis. There is a priori uncertainty regarding the ore type in any given mineable section of the orebody. In addition, there is extracted ore type uncertainty that is introduced by the mining process. These uncertainties are better understood by obtaining more precise (real-time) information. In addition, a better understanding of the uncertainties can improve the quality of operational decisions and increase the overall profitability of the mine. This case study provides a framework for measuring the economic impact of information purchases in a mining context and discusses the implications of those findings. 相似文献
In this paper, we introduce a capital market-based financial guaranty system as an alternative to current insurance guaranty funds and deposit insurance systems. The guaranty system secures clients’ claims for the event of default by the financial company using a special purpose vehicle which issues bonds to investors. The proposed system, analogous to a credit-linked note, consists of one guaranty vehicle for each financial company. In a first step, we present equations in order to derive the two main input parameters of the special purpose vehicle: the premium and the principal. Subsequently, we analyze the impact of different investment actions taken by the financial companies protected by the guaranty vehicle on various shortfall measures. We find that it will be necessary to restrict the investment volume of investors from the financial industry in order to avoid systematic risk within the proposed guaranty scheme. By deriving practical implications, we show that the capital market-based solution has some key benefits compared to current deposit insurance and insurance guaranty schemes. 相似文献
