Marine‐protected areas (MPAs) are an effective means of improving habitat quality and biodiversity in the world’s oceans. While the advantages of MPAs as a mechanism for conservation and biodiversity are well established, the potential improvements to fishery performance resulting from a network of MPAs are still being established. Countries around the world have committed to establishing networks of MPAs within their waters by 2020, in response to the United Nations Convention on Biological Diversity. This, coupled with the increasing global demand for seafood and heavy reliance on fishery resources as a source of economic development for many coastal communities, means that an understanding of how these networks can be expected to impact fishery performance is extremely important. We use a difference‐in‐difference modelling approach to isolate the change in the fishery performance associated with the south‐east marine reserve network in Australia. We find no evidence that the economic performance of adjacent fisheries was negatively impacted by the network. This lack of impact is likely due to a network design explicitly intended to avoid effort displacement in key fisheries, along with fishery management changes intended to remove excess fishing capacity.  相似文献

The purpose of this study was to investigate areas of significance which were related to the understanding of technology and technology education, identified by teachers introducing the key learning area, technology, into their primary school classrooms for the first time. Working from Australia's national document on technology education, A Statement on Technology for Australian Schools (Curriculum Corporation, 1994), two teachers wrestled with how to fit this new curriculum area into their current classroom programs, their understandings of technology as a phenomenon and with their beliefs about teaching and learning in general. The study showed that the teachers made sense of technology education as it related to, from their perspectives, ideas about and aspects of primary school classrooms with which they felt comfortable. Implications for professional development include the need to acknowledge and value the prior experiences and understandings of primary teachers. The challenge for teachers in implementing technology education is gaining a conceptualisation of the learning area, which in some respects, is very like other more familiar learning areas in the primary curriculum, but in many other respects, unique.  相似文献

Bid prices for the demand and supply of water allocations between 2001 and 2007, and average monthly prices paid for water allocations from 1997 to 2007 in the Goulburn–Murray Irrigation District are analysed to estimate price elasticities. Based on bid prices, the price elasticity of demand for water allocations appears highly elastic, with elasticities strongly influenced by the season and drought. The price elasticity of supply for water allocations is also elastic, albeit less elastic than demand. Using actual prices paid, water demand is negatively related to price and is inelastic, and appears to be most influenced by demand the previous month, drought and seasonality factors.  相似文献

There is growing policy interest in charitable giving in the UK. As part of its Big Society agenda, the current government is keen to encourage a higher level of donations, highlighting new technologies, new social norms and tax incentives as potential mechanisms for raising giving. In the 2012 Budget, however, the Chancellor also proposed limiting tax relief on donations to £50,000, sparking an intense discussion about the effectiveness and desirability of tax incentives for major donors. This paper brings together recent evidence relevant to the ongoing policy debates.  相似文献

In this article we describe a holistic, ecological framework that takes into account the surface structures and pedagogical approaches in the studio and how these elements are connected to the construction of design knowledge: epistemology. In our development of this framework, we came to understand how disciplinary underpinnings and academic culture shape the ways that studio is enacted. Using practice theory, we illustrate our framework with two examples—one in Industrial Design and another in Human Computer Interaction—that demonstrate the ways in which the studio can act as a bridge between academic and professional communities. We came to see the studio as a unique practice community that connects academic and professional contexts. We argue that successful implementation of studio-based learning involves an awareness of disciplinary canons, ontological approaches to knowledge, and the academic constraints on studio-based approaches to learning.  相似文献

We formulate a model of capacity expansion that is relevant to a service provider for whom the cost of capacity shortages would be considerable but difficult to quantify exactly. Due to demand uncertainty and a lead time for adding capacity, not all shortages are avoidable. In addition, technological innovations will reduce the cost of adding capacity but may not be completely predictable. Analytical expressions for the infinite horizon expansion cost and shortages are optimized numerically. Sensitivity analyses allow us to determine the impact of technological change on the optimal timing and sizes of capacity expansions to account for economies of scale, the time value of money and penalties for insufficient capacity.  相似文献

The relationship between chief executive officer (CEO) compensation and various organizational variables (i.e., size, length of tenure of the CEO, board composition and firm performance) has been explored in academic research. However, the relationship between CEO compensation and the firm's reputation based on the firm's commitment to the community and the environment has been relatively unexamined in the academic research. This study's purpose is to empirically examine this relationship using the Fortune Reputation Index as revised by Brown and Perry (1995) . Using a sample of 186 firms in 1990 and 188 firms in 1991, the relationships between CEO compensation and organization size, financial performance and environmental reputation are examined. The results of the study demonstrate that there is a strong relationship between CEO compensation and firm environmental reputation, firm size and firm financial performance.

Recent studies have shown convincingly that no 'neocolonialist' conspiracies were hatched to perpetuate British commercial dominance in the former colonies after independence, and that relations between individual firms and policy-makers were frequently troubled. In acknowledging the force of this general proposition, however, there is a risk of neglecting the still significant place of commercial considerations in state policy making. By relocating the relationship of trade and empire in the 1950s in an examination of a hitherto neglected dimension of British taxation policy, this article demonstrates that the Conservative government sought to assist British business with colonial interests at a time when these firms faced new uncertainties.  相似文献
