Climate change is a global problem and across the world there are major difficulties being experienced in reducing carbon dioxide (CO2) emissions. The transport sector in particular is finding it difficult to reduce CO2 emissions. This paper reports on two studies carried out by the authors in London (UK) and Delhi (India). It considers the common objectives for transport CO2 reduction, but the very different contexts and baselines, potentials for change, and some possible synergies.Different packages of measures are selected and scenarios developed for each context which are consistent with contraction and convergence objectives. CO2 reduction potentials are modelled and quantified by package and scenario. London is considering deep reductions on current transport CO2 emission levels; Delhi is seeking to break the huge projected rise in transport CO2 emissions.The scale of policy intervention required to achieve these goals is huge and there is certainly little public discussion of the magnitude of the changes required. The paper argues for a ‘strategic conversation’ at the city level, using scenario analysis, to discuss the priorities for intervention in delivering low carbon transport futures. A greater focus is required in developing participatory approaches to decision making, alongside network investments, urban planning, low emission vehicles and wider initiatives. Aspirations towards equitable target emissions may assist in setting sufficiently demanding targets. Only then is a wider awareness and ownership of potential carbon efficient transport futures likely to take place. 相似文献

The purpose of this study was to explore the relationship between mandatory food safety training and certification and inspection results of chain restaurants and independent restaurants, using current food safety inspection results of food service establishments in Central Florida. More specifically, this study examines whether there is any statistically significant difference in the violation frequency among chain and independent restaurants. Reducing the risk of any foodborne illness is a critical strategy that industry stakeholders should pursue in an area dominated by tourism such as Orlando, Florida. A one-way ANOVA was used to determine the differences between the two types of restaurants. Findings indicate that there is significant difference between chain and independent restaurants for critical violations. No difference was found when comparing chain verses independent restaurants for non-critical violations. 相似文献

Economists’ faith that variable exchange rates benevolently equilibrate has been empirically disconfirmed. That faith is here tackled at its theoretical core with an exchange rate model that although ultra abstract, includes the undeniable fundamentals of market power and differential goals of central bankers and large-scale private players. It permits a game theoretic analysis under the assumption that all agents maximize their payoffs. The paper then relaxes
the assumption of maximising agents, allowing for a more complex and thus realistic second version of the model that is interpretable
within SKAT, the Stages of Knowledge Ahead Theory of risk and uncertainty. In an experimental setting, this second version
of the model points to: a) the inability of agents in central banks, governments and the private real and financial sectors
to operate in maximising ways; b) destructive central bank conflict; and c) the widely discrepant outcomes arising from the
dynamics of individual personality differences. The paper’s theoretical and empirical findings thus both point to the merits
of a single world currency. 相似文献

This paper concludes that a market for state-contingent claims (UK horserace betting) displays evidence of pervasive but heterogeneous forms of inefficiency, in significant contrast to earlier investigations. Using hitherto unavailable data, comparison of notional returns implicit in parallel sets of bookmaker and parimutuel odds identifies inefficiency in terms of zones of distinct but contrasting forms of cross-;market returns differential. The inefficiency is rationalized in terms of both buyer and supplier behaviour; its durability is explained in terms of limited arbitrage opportunities. 相似文献

The conventional wisdom has been that men outperform otherwise equivalent women in collegiate economics courses. Recent work in science, technology, engineering, and mathematics (STEM) fields documenting gains by women suggests that it is time to reevaluate the gender performance gap in economics. Surveying 68 studies containing 235 distinct regressions published since 1980, we find that 68.4% of regressions report men outperform women, though this is only statistically significant in 30.7% of regressions. Although the literature points to numerous reasons for this gap, our focus is on the effects of study design and the impact of broad socio-cultural changes over time. Using meta-regression analysis, we find that the likelihood of observing a statistically significant gap has declined noticeably, by almost 3% annually. Although the drop may not be as large as in some STEM fields, the result is highly robust to the specification of the time trend and the model. 相似文献

I have recently been thinking of how to be “virtuous” as I engage in doing qualitative research for social justice. In this essay, I explore the complexities and risks involved in representing the researcher-self amidst competing (and perhaps false) dichotomies of the personal/professional life and the scholar/activist. To do so, I deconstruct places in my scholarship where I was willing (consciously and unconsciously) to take risks, where I took risks but was socialized to conform, where I am still unwilling to take the risk and where I am currently writing the risky. The goal is to create a dialogue about the perplexities that surround representing the “researcher self” with goals for social justice. 相似文献

Interviews were conducted in Kitchener‐Waterloo, Ontario, at eight different recreation areas. These were classified as either designated or nondesignated recreation areas. The interview was designed to obtain information regarding demographic characteristics of the user, attitudes toward the use of urban recreation areas (both playgrounds and areas that are not designated as recreational in character), reasons for choosing a particular recreation site and what users considered to be part of an ideal recreation area. Information gathered by the interview method was supplemented by a series of observations. Results indicated a significant difference between age and reasons for nonattendance at designated play areas. Differences in use by sex were, however, not significant. 相似文献

Most studies that examine tourism impacts and community attitudes have been carried out from the perspective of industrialized economies, making the findings less valid for small islands. This paper discusses some pertinent issues in relation to tourism development and community attitudes in small islands, and it develops and presents a conceptual framework based on social exchange theory and identity theory. The different facets of identity relevant to small-island communities that are likely to influence attitudes and support for tourism are incorporated in the framework and discussed. These include occupational identity, environmental identity and gender identity. Based on these, five propositions are developed. The study concludes that inclusion of identity variables in behavioral models could increase their predictive power in explaining attitudes to tourism and consequent support for the industry. 相似文献

The purpose of this article is to identify the extent of inward and outward foreign direct investment (FDI) worldwide. A large number of countries were aggregated on a regional basis to examine their inward and outward stocks as a percentage of gross fixed capital formation for the period 1980–2006. Among the findings was that the annual increase for both inward and outward FDI was less than 1%. Also, countries grouped by the aggregates developed, Africa, Latin America and Caribbean, Asia and Oceania, and developing were found to differ significantly in their means. 相似文献
