Learning teaching in the sustainability classroom

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.     

Expanding the Tension‐Reduction Model of Work Stress and Alcohol Use: Comparison of Managerial and Non‐Managerial Men and Women*

abstract The tension‐reduction model that links workplace stress to alcohol use and problems has received mixed support in previous investigations. Following recommendations that this model include moderated mediated relationships ( Frone, 1999 ) using more specific forms of workplace stress, we examine the impact of gender ratio, generalized workplace abuse, and stereotype threat in an effort to predict alcohol use and problems particularly for managerial women. A total of 1410 (57 per cent response rate) employees completed a survey containing items on job stress, escapist reasons for drinking, and alcohol consumption and problems, and SEM analyses were conducted separately for managerial and non‐managerial men and women. Results revealed that: (a) these three workplace stressors were differentially related to general workplace stress for the four groups; and (b) the contributions of the three stressors and of general work stress to the alcohol‐related variables varied by group.     

Technology acceptance: Not all organisations or workers may be the same

The Technology Acceptance Model (TAM) is widely accepted by researchers in the IT field as a reliable tool able to predict acceptance of new technology by individuals. The majority of these studies have used participants (both students and non-students) from within traditional businesses functions, e.g., accounting and finance. The ability of TAM to predict technology acceptance across all situations is not well documented. During the past decade there has been an increasing interest in research within Not-for-Profit (NFP) organisations. This paper considers whether people likely to pursue careers within the NFP sector have different attitudes to technology and whether such differences affect the measures used within technology acceptance models. A survey of business and social science undergraduate students, those most likely to enter careers in the Business vs. the NFP sector, indicated differences between the two groups that may impact on the technology acceptance models.     

Does reduced trade tax revenue affect government spending patterns?

Many skeptics of trade liberalization in the developing world argue that lowering trade taxes can cause significant fiscal pressures in countries particularly reliant on these taxes and result in a reallocation of resources away from important development goals. This paper evaluates whether there is evidence that central governments systematically change the composition of spending priorities in the wake of lowered trade tax revenues as a share of total government revenues. We find no systematic evidence for this concern in a sample of 51 developing countries for the 1991 through 2005 period.     

Die Kosten des Klimaschutzes am Beispiel der Strompreise für private Haushalte

Power prices in Germany have been surging since the outset of the new millennium. Among the major reasons for this tendency are newly raised taxes and levies on electricity prices, whose introduction is primarily motivated by climate concerns. Without these taxes and levies, net electricity prices would have remained constant for private households. This article discusses these taxes and levies that have been responsible for the cost increases in private households’ electricity consumption. Most influential have been the feed-in tariffs for renewable energies, above all photovoltaics. According to our calculations, the levy for renewables will further increase in the up-coming years, thereby pushing consumers’ electricity cost once again. Our calculations also show that within the next couple of years, there will be a fierce competition among renewable energy technologies, most notably between photovoltaics and wind power. Politics would be well-advised, therefore, to limit the annual capacity of newly installed solar modules in order to avoid both the explosion of consumers’ electricity bills and strong competition among renewables.     

A SURVEY OF MEASUREMENT BIASES IN PRICE INDEXES

Abstract. This paper reviews the literature on measurement error in the major US price indexes—the Consumer Price Index (CPI), the Producer Price Index (RPI), and the Gross Domestic Product (GDP) deflators. We take as our point of departure Triplett's, 1975, survey and focus on the studies of measurement error that have appeared since then. We review the problems of substitution bias, quality bias, new goods bias, and outlet substitution bias that are generally considered to be the main sources of error in price indexes. The bulk of the paper is devoted to problems in the CPI and PPI, as the GDP deflators tend to be based mainly on the components of these series. We find that there has been surprisingly little work on the problem of overall measurement error in any of these price indexes, and we conclude that there is very little scientific basis for the commonly accepted notion that measured inflation at 2 to 3 percent a year is consistent with price stability.     

Investment sequencing in the brick industry: an application of grounded theory

Since the work of George Richardson on the problem of investmentcoordination, the literature has focused on explaining equilibriumin investment games and neglected the problem of how investmentsare coordinated. This paper reports the findings of a case studyof the brick industry which used grounded theory techniquesto develop a new analysis of investment coordination. Our mainfindings indicate that, despite the high cost of excess capacityand the very clear signalling of investment intentions, brickfirms are reluctant to stand back and delay their own investmentswhen a rival firm is expanding. The fact that for the most partexcess investment is avoided is explained by reference to firms'heterogeneity and constraints to investment.     

International transmission of monthly changes in equity values

Our purpose is to answer two questions pertinent to the international transmission of changes in equity values. First, do lead-lag relationships documented in short-horizon (daily) studies continue to hold in longer time (monthly) horizons? Second, does the lead-lag structure remain stable over time? The questions are answered by examining monthly equity returns for nine countries during the 1980s. We find evidence that is somewhat surprising—significant lead-lag relationships among some countries persist in monthly horizons, particularly during the first half of the 1980s. During the second half, the lead-lag relationships are substantially weaker. During the same period, we find that contemporaneous correlations across countries have largely increased, implying greater influence of worldwide factors in determining equity prices.     

Schedule jockeying and route swamping: bus markets in Britain need kerb rights

The experience of British bus deregulation has resulted in less on-the-road competition than anticipated, and a high degree of industry concentration We argue that the specific form of deregulation in Britain has created a property rights problem in the cultivation of passenger congregations at the kerb. The result has been schedule jockeying and route swamping . From a property rights perspective, the disappointing results can be seen as a commons problem. A nuanced approach to property rights at bus stops, permitting scheduled service to appropriate its investment in cultivating passenger congregations, and allowing freewheeling jitneys to compete on the route, could bring the benefits that many had expected from deregulation.
