How suburban ways of living are shaping the geography of income in Canadian cities
The traditional view of North American suburbs is that they are populated by those on relatively high incomes who own their single-family home. Mark Williamson and Robert Walter-Joseph report on a new study which challenges the established view of where suburban life is located. They write that by studying all of Canada’s 26 major metropolitan areas, researchers found many central city neighborhoods which exhibited high proportions of suburban-style living, as well as peripheral areas that had more urban characteristics. They write that ‘suburbanism’ is as much about where income is concentrated as it is about aspects of the built form. It is not solely about being outside a city center
Invasion science, ecology and economics : seeking roads not taken
As members of the editorial board of Neobiota who, for various reasons, didn’t get our names on the original editorial (Kühn et al. 2011), we would like to add a coda to it. Even though there were 38 bullet points listing areas in invasion science where more work is needed, we would like to mention additional areas that we hope would be addressed in future issues of Neobiota. Like the other editors, we would like this innovative and exciting new journal to lead the way in all areas of invasion science. As the graphs in Gurevitch et al. (2011) and Kühn et al. (2011) show, the literature on invasions has been increasing almost exponentially since the early 1980s and so we cannot expect any list of areas of interest to stay complete and up to date for very long. Three areas that we would like to stress are the interaction between invasion science and economics and the role that invasion science should play in advancing pure ecology in two areas, population dynamics and ecosystem ecology. Neither ecology nor economics appears as a word in the original bullet list, but many of the topics are obviously ecological while none are obviously economic. For economics, we want to point out its relevance to invasion science and the feedback between the two disciplines, particularly in a rapidly changing world with powerful new emerging economies. For ecology, we want to emphasise not what ecology tells us about invasions but what invasions reveal about ecology and evolution at two scales
Environmental Restoration of Invaded Ecosystems: How Much Versus How Often?
This paper derives the optimal level of restorative efforts required to restore environments degraded by invasive species invasion. Specific attention is focused upon a case when the restoration efforts face the risk of failure through relapse of the restored environment. The level of restored environment may also play a role in its future improvement or susceptibility to failure. The tradeoff between the optimal level of environmental quality and number of restorative efforts required to attain that given environmental quality is analyzed.environmental restoration, resiliency, restoration failure, invasive species, Environmental Economics and Policy,
The Computational Power of Minkowski Spacetime
The Lorentzian length of a timelike curve connecting both endpoints of a
classical computation is a function of the path taken through Minkowski
spacetime. The associated runtime difference is due to time-dilation: the
phenomenon whereby an observer finds that another's physically identical ideal
clock has ticked at a different rate than their own clock. Using ideas
appearing in the framework of computational complexity theory, time-dilation is
quantified as an algorithmic resource by relating relativistic energy to an
th order polynomial time reduction at the completion of an observer's
journey. These results enable a comparison between the optimal quadratic
\emph{Grover speedup} from quantum computing and an speedup using
classical computers and relativistic effects. The goal is not to propose a
practical model of computation, but to probe the ultimate limits physics places
on computation.Comment: 6 pages, LaTeX, feedback welcom
