Urban Political Ecologies and Children's Geographies: Queering Urban Ecologies of Childhood

This article focuses on the material and discursive constructions of nature and children in the city. While dominant representations and idealizations of nature and childhood depend on the binary logic of the nature/culture and rural/urban divide, there is also a simplification and romanticization of nature in children's geographies and a lack of children and their spaces in urban political ecology. We argue that children and nature in cities need to be removed from a binary model of being and attended to in more nuanced ways in urban political ecology and children's geographies. In this regard, we suggest that both nature and children in cities need to be queered. We need to ask how the production of urban spaces (re)creates particular romantic and idealized relations with natures that reify the binaries between nature/culture, and male/female through a heteronormative framework. The purpose of this article is to bring the critical nature–society theories of urban political ecology into conversation with work in children's geographies that explores the ‘nature' of childhood, and in doing so queer the relationship between children and nature. Drawing on research on queer ecologies, and queered childhoods, we aim to provide a framework to rethink and queer both nature and children in cities.     

Bivariate garch estimation of the optimal commodity futures Hedge

Six different commodities are examined using daily data over two futures contract periods. Cash and futures prices for all six commodities are found to be well described as martingales with near-integrated GARCH innovations. Bivariate GARCH models of cash and futures prices are estimated for the same six commodities. The optimal hedge ratio (OHR) is then calculated as a ratio of the conditional covariance between cash and futures to the conditional variance of futures. The estimated OHRs reveal that the standard assumption of a time-invariant OHR is inappropriate. For each commodity the estimated OHR path appears non-stationary, which has important implications for hedging strategies.     

Home Equity,Household Savings and Consumption

The home-owning family’s equity is a piggybank that can be broken open by borrowing. Each borrowing increases liabilities and cash equally, initially leaving net wealth unchanged. When those funds are spent and cash balances fall, consumption increases even as net wealth can decline. In a dynamic optimization, the marginal propensity to consume from net wealth is not always positive and can be positively correlated with housing debt.

The influence of judges' attitudes on liability assessments related to failed audits exhibiting significant audit team over-time or significant use of off-shore auditors

This study provides evidence on how audit firms' decisions to use offshore (outsourced) auditors or to assign on-site (local) auditors extensive overtime affect judges' evaluation of auditor legal liability I conduct a behavioral experiment in which actual judges responded to a hypothetical audit lawsuit. The results suggest auditors may be penalized during the litigation process depending on the extent of overtime or off-shoring and judges' attitude toward the public accounting profession. Judges with a positive attitude toward public accounting assessed more liability for an audit firm that used offshore (outsourced) auditors than for the use of extensive overtime for on-site auditors or a control condition. However, judges with a negative attitude toward the auditing profession assessed higher liability for auditors except when on-site auditors bore significant overtime in the final weeks of the audit.     

Zeitgeist leadership

Companies and leaders don't succeed or fail in a vacuum. When it comes to longterm success, the ability to understand and adapt to changing business conditions is at least as important as any particular personality trait or competency. A clear picture of how powerful the zeitgeist can be emerges from the authors' comprehensive study of the way the business landscape in the United States evolved, decade by decade, throughout the twentieth century. Six contextual factors in particular, they found, most affected the prospects for business: the level of government intervention in business, global events, demographics, shifts in social mores, developments in technology, and the strength or weakness of the labor movement. A lack of contextual sensitivity can trip up even the most brilliant executive. No less a luminary than Alfred P. Sloan was relieved of GM's day-to-day management in the 1930s because he was unwilling to meet with the new UAW. Conversely, an understanding of the zeitgeist can play a crucial but unheralded role in business performance. Jack Welch is widely credited with GE's remarkable success during the 1980s and 1990s, for example, but far less attention has been paid to his predecessor, the statesmanlike and prudent Reginald Jones, who sustained strong revenue and profit growth during the heavily regulated stagflation of the 1970s. To better understand this connection between business performance and context, the authors studied 1,000 great U.S. business leaders of the twentieth century and identified three distinct archetypes: Entrepreneurs, often ahead of their time, overcame dire challenges to build something new. Managers excelled at reading and exploiting the existing zeitgeist to grow their businesses. Leaders defied context to identify latent potential in businesses others considered mature, stagnant, or in decline. In every decade, all three archetypes were vital. It is the ongoing regeneration of this pattern in the business life cycle that ultimately sustains development and progress.     

Modeling the urban land market: The case of Japan

Two sets of negative exponential functions, one for urban residential density and the second for land price, are estimated. The parameters of these functions are then employed in an econometric model of land use and urban form in 71 Japanese cities. Several variables are determined, including average land price, gross population density, housing size, and population.     

WHAT AUSTRIAN BUSINESS CYCLE THEORY DOES AND DOES NOT CLAIM AS TRUE

Contemporary economic commentators have a habit of dismissing Austrian business cycle theory on the grounds that the implications for policy responses are unconvincing. Often the ‘Austrian’ position is misunderstood. But even if we wish to draw on other schools of thought to understand depressions, this does not affect the importance of Austrian insights to explain the boom.     

Steekproeven uit de halve cauchy verdeling

Summary Let x₁…, x_n be a sample from a distribution with infinite expectation, then for n→∞ the sample average x?_n tends to +∞ with probability 1 (see [4]). Sometimes x?_n contains high jumps due to large observations. In this paper we consider samples from the “absolute Cauchy” distribution. In practice, on may consider the logarithm of the observations as a sample from a normal distribution. So we found in our simulation. After rejecting the log-normality assumption, one will be tempted to regard the extreme observations as outliers. It is shown that the discarding of the outlying observations gives an underestimation of the expectation, variance and 99 percentile of the actual distribution.     

Complexity, Governance and Constitutional Craftsmanship

Economic policy is commonly treated as a vehicle for selecting among possible allocative outcomes within an economy. An economy, however, is a complex network of relationships whose patterns can be understood but whose details can be neither predicted nor controlled. Because of this complexity, allocative outcomes are not direct objects of choice. They are simply emergent consequences of human interaction that takes place within some framework of governing rules and conventions. All economic policy can do is modify some of the rules that govern this interaction. Economic policy is thus constitutive and not allocative in character, being centrally involved in shaping the character of the regime that governs our relationships with each other.
