| conflicting interests in toronto: anatomy of a controversy at the interface of academia and industry. | in december 2000, the university of toronto breached a contract it held with me, initiating a sequence of events that has led to a public letter to the university from a large number of senior figures in the psychopharmacology community, protesting against the infringement of academic freedom involved, and a first-ever legal action seeking redress for violation of academic freedom. this case has been intertwined from the start with a longer running debate about the possibility that the ssri grou ... | 2002 | 11919383 |
| associations between indicators of livestock farming intensity and incidence of human shiga toxin-producing escherichia coli infection. | the impact of livestock farming on the incidence of human shiga toxin-producing escherichia coli (stec) infection was assessed by using several livestock density indicators (ldi) that were generated in a systematic approach. a total of 80 ldi were considered suitable proxy measures for livestock density. multivariate poisson regression identified several ldi as having a significant spatial association with the incidence of human stec infection. the strongest associations with human stec infectio ... | 2002 | 11927021 |

| the importance of being marginal: norma ford walker and a canadian school of medical genetics. | this study reviews the development of a medical genetics research tradition in toronto, canada. this research tradition, what i call the "ford walker school," was forged in the 1930s in an iconoclastic mold. it was female-dominated in an era when leading-edge science was definitely not "women's work." it emerged in a leading research university, but in a country that lagged in the sciences. these social relations of gender and nation symbolized and sustained a marginality that was reinforced by ... | 2002 | 12400056 |

| insulin: discovery and controversy. | during the first two decades of the 20th century, several investigators prepared extracts of pancreas that were often successful in lowering blood sugar and reducing glycosuria in test animals. however, they were unable to remove impurities, and toxic reactions prevented its use in humans with diabetes. in the spring of 1921, frederick g. banting, a young ontario orthopedic surgeon, was given laboratory space by j.j.r. macleod, the head of physiology at the university of toronto, to investigate ... | 2002 | 12446492 |

| seeing double, thinking twice: the toronto drag kings and (re-) articulations of masculinity. | through a close reading of the performances of masculinity by the toronto drag kings, this chapter argues that drag king shows parody the hyper-masculine star at his most contradictory and dialogic. given that drag king performances parody both the contradictions of masculinity on stage, and the productive technologies of the star, king performances are essentially both meta-theatrical (performances about performing where lights, music, body language, dance all make the man) and meta-performativ ... | 2002 | 12769283 |

| conservation of endangered species and the patterns and propensities of biodiversity. | it is commonly asserted in the ecological and economic literature that habitat loss is the main cause of loss of imperiled species. the evidence clearly shows that habitat loss is a common contributing factor, but there is little evidence that it is the most important factor. studies that have focused on the mechanisms of species loss have failed to produce models capable of predicting patterns of loss as a function of human activities. i propose that this is because ecologists have employed an ... | 2003 | 14558457 |

| noninvasive phenotypes of atherosclerosis: similar windows but different views. | noninvasive measures of atherosclerosis, such as carotid intima-media thickness, total carotid plaque area, and carotid stenosis, probably represent different phenotypes with distinct determinants. for instance, total carotid plaque area may reflect atherosclerotic lesion size more closely than carotid stenosis, which instead may reflect hemodynamic compromise within the arterial lumen. | 2004 | 14963285 |
| the changing costs of radiation treatment for early prostate cancer in ontario: a comparison between conventional and conformal external beam radiotherapy. | prostate cancer represents a large part of the workload for radiation oncology departments in canada. recent evidence suggests that conformal external beam radiotherapy improves results. the planning and treatment process for conformal patients requires a greater amount of resources that are in short supply in ontario. an understanding of these differences is important to provide an accurate estimate of future radiation needs of the province. these differences can be quantified in a cost model t ... | 2004 | 15003151 |
| the urban geography of sars: paradoxes and dilemmas in toronto's health care. | severe acute respiratory syndrome (sars) has impacted heavily on both canada's society and its health care system. quite unexpectedly, hospitals and health care workers became facilitators of disease diffusion. this experience has demonstrated the need for a comprehensive disease control strategy. | 2004 | 15012634 |
