This chapter assesses the relationship between urban form and accessibility by comparing accessibility across metropolitan regions in the United States. A prevalent view among urban planning researchers is that low-density, auto-oriented metropolitan regions are also low-accessibility areas. This view, if supported, would have important implications for policy reform. For metropolitan areas in the U.S. overall, there is a positive relationship between density and auto accessibility. This suggests that land-use policy can be highly relevant to accessibility outcomes. In particular, allowing metropolitan compactness by easing land-use regulations mandating low development densities can improve the effectiveness of the roadway transportation system as defined in accessibility terms. Yet the success of the strategy remains a matter for empirical accessibility evaluation. The relationship between metropolitan density and work accessibility via automobile, while positive, is hardly ironclad, and some low-density regions do offer high auto accessibility. And transportation success overall should not just consider the automobile but should consider accessibility via all travel modes, including walking, cycling, public transport, and cars.

This article understands, from an empirical perspective, the determinants of carbon emissions, using internationally comparable data, and cross-national regressions for India and China. Next, it explores the relationship between urban land use regulations and carbon emissions in India’s cities. Urbanization has no impact on carbon emissions per capita or per unit of geographical area. Electricity consumption in China and electricity produced from coal in India have a positive effect on carbon emissions. GDP per capita has a positive effect in India and not so in China, but per capita GDP squared has a negative impact on emissions in both the countries. Does this imply that urbanization should be ignored in the two countries? The answer is no, because a city’s urban form, to which policy contributes, is correlated with carbon emissions. More suburbanized cities which sprawl more also emit more carbon. India’s land use regulations relating to building height restrictions are conservative, hence Indian cities sprawl, which lead to carbon emissions. Hence, the focus of urban policy has to be on the development of compact cities. The article concludes with caveats of the data.

This paper argues that the low-density, single-use character of most suburban workplaces in the U.S. has contributed to worsening traffic congestion by making most workers highly dependent on their own automobiles for accessing jobs. To test this proposition, land use and transportation data are examined for fifty of the largest suburban employment centers in the nation. Differences in the share of trips made by various modes, commuting speeds, and levels of service on major thoroughfares connecting suburban centers are compared among clusters of centers. The densities, sizes, and land use mixtures of suburban workplaces are generally found to be important determinants of worker travel behavior and local traffic conditions.

Second Life is a virtual world designed to be a free, laissez-faire market economy in which Linden Dollars are used to buy and sell goods and services. This study investigated the relationship between the economies of Second Life and the United States, using financial data collected from Linden Lab and the Federal Reserve. Partial correlation analyses were computed between two pairs of economic measures, and our results indicated that there was a significant relationship between the two economies.

ABSTRACT The study compares the relationship between wages and labor productivity for different categories of workers in Brazil and in the U.S. Analyses highlight to what extent the equilibrium between wages and productivity is related to the degree of economic development. Wages in the U.S. has shown to be more attached to labor productivity, while Brazil has experienced several economic cycles were average earnings grew initially much faster than labor productivity, suddenly falling down in the subsequent years. Analyses also stress how wage differentials, in fact, match productivity differentials for certain occupational groups, while for others they do not.

The main aim of this study was to test whether there is a positive relationship between different financial risk measures and the expected return of a share. This study was performed in 1995 by Brümmer and Wolmarans, who obtained results contrary to those of a similar study in the United States of America in 1988. The reasons for the difference were not established. This study follows up the one by Brümmer and Wolmarans to determine whether the passing of 19 years could have brought about any difference in the results. This process was initiated by testing a set of variables from a sample size of 107 JSE-listed companies from 2002 to 2012 for linearity. As there was no such linear relationship between any of the variables, no assumptions can be made about any relationship between share return and the risk measures tested here. If investors were risk averse, one would expect a positive relationship between different financial risk measures and the expected return of a share. This is not the case in the South African market.

Anne Case et al. (2002), using cross-sectional data, found a positive relationship between children's health and income, with income's protective effect increasing with age. Janet Currie and Mark Stabile (2003), using a panel of Canadian children, found that low- and high-SES children respond similarly to health shocks, but the low-SES children are subject to more shocks as they age. Our study examines this relationship using panel data for US children. We find some support for the latter result of Currie and Stabile, but also evidence that low- and high-SES children respond differently to specific health shocks. (JEL D31, I12, J13)

Abstract China has a civil procedure for collective litigation, which is dubbed Chinese-style class action, as it differs from the U.S.-style class action in some important ways. Using securities class action as a case study, this Article empirically examines both the quantity and quality of reported cases in China. It shows that the number of cases is much lower than expected, but the percentage of recovery is significantly higher than that in the United States. Based on this, the Article casts doubt on the popular belief that China should adopt the U.S.-style class action, and sheds light on the much-debated issue concerning the relationship between public and private enforcement of securities law. The Article also discusses the future prospects of securities class action in China in light of some recent developments which may provide its functional equivalents, including the regulator-brokered compensation fund and public interest group litigation.

ABSTRACT A new subgroup of avian leukosis virus (ALV) that includes a uniqueenv gene, designated J, was identified recently in England. Sequence analysis of prototype English isolate HPRS-103 revealed several other unique genetic characteristics of this strain and provided information that it arose by recombination between exogenous and endogenous virus sequences. In the past several years, ALV J type viruses (ALV-J) have been isolated from broiler breeder flocks in the United States. We were interested in determining the relationship between the U.S. and English isolates of ALV-J. Based on sequence data from two independently derived U.S. field isolates, we conclude that the U.S. and English isolates of ALV-J derive from a common ancestor and are not the result of independent recombination events.

A number of church activities in the United States and in various Third World nations bring issues involving the separation of Church and State once again to the fore. Certainly any serious inquiry into the relationship of the U.S. Government and American missionary groups abroad—particularly with regard to the First Amendment to the U.S. Constitution—must first consider the historical record. Only after a thorough examination of the inconsistencies and constradictions between theory and practice over the nation's more than two hundred-year history can one hope to assess present policies. This, then, is just such an historical overview.
