This article analyzes the experience of a particular sustainability learning classroom model, examining the classroom composition, structure, positioning, and atmosphere components in an experimental course on the topic of sustainable buildings. The course, called Angles on Green Building, offered as the second in a suite by the Learning City sustainability in higher education collaborative, experimented with content, which concerned the emerging practice and policy of green building, and with form, exploring the most appropriate pedagogical methods for the advancement of sustainability learning and action. The course took as its practical focus the green building industry in Vancouver, Canada, with an initial case study of the new Centre for Interactive Research on Sustainability (CIRS), a green building and research facility planned for completion in 2009. This article uses evidence drawn from the instructors, students and visiting professionals in the course, together a diverse and interdisciplinary group from four different higher education institutions in Vancouver. Our findings contain lessons about the careful attention needed for instructors to design, run and implement courses in sustainability topics that enable students from widely different backgrounds and levels of self-directedness to engage with, take responsibility for, and transform their behaviours in favour of sustainability. 相似文献

This paper empirically investigates the effects on the weekly returns of almost 100 banking organizations of the December 1982 authorization of Super NOWs. Examination of excess returns around the announcement date suggests that the announcement of the Super NOWs had a statistically significant (and negative) effect and that the impact differed significantly by type of bank. While returns for money center banks were generally unaffected, excess returns for regional retail banks were highly significant. 相似文献

The fact that there are times when market movement is random and times when it is not is interpreted in terms of the hypothesis that the price of a stock is an aggregate opinion — the resultant of the opinions and decisions of a community of investors. Price, like any other opinion, will be most vulnerable to social and other sources of influence during times of uncertainty, an aggregate psychological state which can generate the kind of statistical dependence characteristic of non-random walks. Ramifications of this hypothesis are explored in a variety of stock market behaviors, such as the effect of tips, the impact of runs on trading volume during rising and falling markets, and the like. 相似文献

This paper provides a new approach to validate the feasibility of schedules of multiple-step mixed-model unstable manufacturing environments with different changeover times. Traditionally, continuous lines in a manufacturing process run the same sequence in order to minimize WIP inventory and lead time. Nevertheless, multiple reasons such as different product mixes or setup times can lead managers to run different sequences in continuous lines. Unfortunately, lack of reliability of supply and demand in these environments makes it difficult to manage product inventories and often leads to starvation due to the discoordination between the schedules of both lines. This approach is based on a new type of visual representation of schedules and an estimate the probability of starvation. It assumes stochastic supply and demand and a predefined schedule sequence based on batches of different sizes. 相似文献

Over the past dozen years, policymakers have largely abandonedlong-standing popular approaches for addressing risk in agriculturewithout fully resolving the question of how best to manage thenegative consequences of volatile agricultural markets. Thearticle reviews the transition from past policies and describescurrent approaches that distinguish between the trade-relatedfiscal consequences of commodity market volatility and the consequencesof price and production risks for vulnerable rural householdsand communities. Current policies rely more heavily on markets,even though markets for risk are incomplete in numerous ways.The benefits and limitations of market-based instruments areexamined in the context of risk management strategies, and innovativeapproaches to extend the reach of risk markets are discussed. 相似文献

This study attempts to measure with a two-region model some of the key economic relationships for Canadian wheat in the world market. The excess demand function facing Canadian wheat exports was found to be price elastic. Dynamic policy multipliers were derived to calculate the effects on wheat exports and the world price of changes in policy instruments including the initial payment for wheat.
Cette étude a pour but de mesurer, au moyen d'un modèle portant sur deux régions, quelques-uns des principaux rapports économiques entre l'économie canadienne du blé et les marchés mondiaux. La fonction de demande excédentaire des exportations canadiennes de blé s'est vérifiée élastique par rapport au prix. Les effets de changements dans les instruments de la politique agricole, tels que le paiement initial du blé, sur les exportation canadiennes et sur le prix mondial du ble ont eté calcule au moyen de multiplicateurs dynamiques. 相似文献

The Saskatchewan short-term hog loan program of 2002 provided a nonmarket credit-line to participating hog producers. The repayment conditions for cash advances committed to by the provincial government depend on later hog prices, and so the program has derivative contract attributes. We model the contracts and use an estimated spot price stochastic process to establish summary statistics for producer benefits from the program .
Le programme de prêt à court terme que la Saskatchewan a offert à ses producteurs de porcs en 2002 comprenait une ligne de crédit non marchande. Comme les modalités de remboursement des avances de fonds engagées par le gouvernement provincial dépendent du prix futur du porc, ce programme possède les caractéristiques d'un instrument dérivé. Nous avons modélisé les contrats et nous avons utilisé un processus stochastique pour estimer le prix au comptant en vue d'établir des statistiques sommaires sur les avantages que les producteurs retirent de ce programme. 相似文献

A key rationale offered by the Federal Reserve for the payment of interest on reserves was to remove the incentive for banks to operate sweep accounts. Sweeping shifts funds from transactions deposits subject to reserve requirements to non-reservable deposits. This paper extends a conventional banking model to analyze sweeping behavior. Sweeping responds positively to increases in bank loan rates and reserve ratios and negatively to increases in the interest rate on reserves or exogenous increases in bank equity. Sweeping generates greater responsiveness in lending to changes in loan rates or the interest rate on reserves and lower responsiveness to changes in reserve ratios or equity than in its absence. Empirical analysis of an explicit condition that we derive suggests that, with an unchanged reserve requirement, the Fed could eliminate sweeping by setting the interest rate on reserves to no less than approximately 4% points below the market loan rate. 相似文献
