At home in the margins
This photo essay explores what constitutes 'home' for people living with HIV in Vancouver's Downtown Eastside. It is a collaboration between myself and eight community researchers - four women and four men - who are living with HIV and have experienced significant periods of homelessness in this context. Over the course of four weeks in 2011, the community researchers were trained in Photovoice...
متن کاملScale-Space Mutual Information for Textural-Patterns Characterization
The essence of image texture is typically understood by two aspects. First, within a texture-pattern there is a significant variation in intensity values between nearby pixels. Second, texture is a homogenous property at some spatial scale larger than the spatial resolution of the image. Motivated by the essential aspects of image texture, this paper proposes a novel methodology that combines t...
متن کاملReducing the Excess Variability at the Margins
Penalized splines have become a popular tool to model the trend component in economic time series. The outcome of the spline predominantly depends on the choice of a penalization parameter that controls the smoothness of the trend. This paper derives the penalization of splines by frequency domain aspects and points out their link to rational square wave filters. As a novel contribution this pa...
متن کاملSlow Tourism at the Caribbean’s Geographical Margins
The Caribbean tourism industry owes much of its success to beneficial geograph ical site and situation factors. Yet these geographical advantages have also contributed to the mass tourism-related pressures of economic dependency, social division and environmental degradation. We argue geographically marginal locales in the Caribbean have the potential to develop alternative tourism models that...
متن کاملEvolved dispersal strategies at range margins.
Dispersal is a key component of a species's ecology and will be under different selection pressures in different parts of the range. For example, a long-distance dispersal strategy suitable for continuous habitat at the range core might not be favoured at the margin, where the habitat is sparse. Using a spatially explicit, individual-based, evolutionary simulation model, the dispersal strategie...
