The physiology of inscription : Foucault's genealogy as curative science

In ''Nietzsche, Genealogy, History," Foucault suggests that genealogy is a sort of "curative science." The genealogist must be a physiologist and a pathologist as well as an historian, for his task is to decipher the marks that power relations and historical events leave on the subjugated body; "he must be able to diagnose the illnesses of the body, its conditions of weakness and strength, its breakdowns and resistances, to be in a position to judge philosophical discourse." But this claim seems to be incongruent with another major task of genealogy. After all, genealogy is supposed to show us that the things we take to be absolute are in fact discontinuous and historically situated: "Nothing in man-not even his body-is sufficiently stable to serve as the basis for self-recognition or for understanding other men." If this is true, then the subjugated body can never be restored to a healthy state because it has no essential or original nature. There are no universal standards by which we can even distinguish between healthy and unhealthy bodies. So in what sense is genealogy to be a "curative science"? In my thesis, I try to elucidate the complex relationship between genealogy and the body. I argue that genealogy can be a curative science even while it "multiplies our body and sets it against itself." Ifwe place a special emphasis on the role that transgression plays in Foucault's genealogical works, then the healthy body is precisely the body that resists universal standards and classifications. If genealogy is to be a curative science, then it must restore to the subjugated body an "identity" that transgresses its own limits and that constitutes itself, paradoxically, in the very effacement of identity. In the first chapter of my thesis, I examine the body's role as "surface of the inscription of events." Power relations inscribe on and around the body an identity or subjectivity that appears to be unified and universal, but which is in fact disparate and historically situated. The "subjected" body is the sick and pathologically weak body. In Chapters 2 and 3, I describe how it is possible for the unhealthy body to become healthy by resisting the subjectivity that has been inscribed upon it. Chapter 4 explains how Foucault's later works fit into this characterization of genealogy

Exploring the relationship between ethnicity and hypertension in Canada

Background: Previous work examining differences in hypertension across ethnic groups employ race as the principal variable. While differences in hypertension have been identified across racial groups, there is great variation between ethnic groups amongst racial groupings that could mask differences in hypertension and cardiovascular disease (CVD) risk. In light of Canada's ethnic diversity, research aimed at identifying specific groups that are at a health disadvantage is essential for understanding the health of the overall population. In addition, this research would be beneficial for creating programs and policies aimed at reducing or eliminating these disparities. Since CVD is the leading cause of mortality in Canada and hypertension is one of the most significant and modifiable risk factors for CVD, it is important to move past crude classifications based on race and examine ethnic group differences. The purpose of this study is to examine the relationship between ethnicity and hypertension in Canada, while employing more narrow classifications for ethnicity than previous studies. In addition, because ethnicity has been shown to be representative of an individual's social experience, this study also aims to investigate whether this relationship can be explained by one or all of the following variable: socioeconomic status, physical activity, body mass index, smoking status, daily alcohol consumption or acculturation. Methods. This study used the 2004 Canadian Community Health Survey, cycle 2.1 to compare 29 different ethnic groups in Canada on whether they had high blood pressure that had been diagnosed by a health professional. Associations were examined using logistic regression. Subsequent logistic regression analyses included socioeconomic status, physical activity, body mass index, smoking status, daily alcohol consumption and acculturation to test for the effect of each of these variables on the relationship between ethnicity and hypertension. Results. Ukrainians, Chinese, Portuguese, South Asians, Aboriginals, Blacks, Filipinos and South East Asians were found to have significantly higher odds of having high blood pressure than Canadians (OR's = 1.50, 1.56, 2.72, 1.38, 1.36, 1.66, 2.21 & 2.24 respectively, p<.001). In addition, the only significant mediating effects were between SES and Aboriginals as well as obesity and Aboriginals. None of the other independent variables accounted for >10% of the risk experienced by the ethnic groups that were significantly associated with hypertension. Interpretation: The odds of having high blood pressure in Canada varies considerably across ethnic groups within racial groups indicating previous research is not specific enough to inform policy and program development. Because this study was not able to explain this relationship using the sociodemographic and lifestyle factors mentioned above, future research should be done to determine what places certain ethnic groups at a greater risk in order to tailor interventions aimed at reducing high blood pressure that are suited to the specific needs of each cultural group.

Larval habitat associations with human land uses, roads, rivers, and land cover for Anopheles albimanus, A. pseudopunctipennis, and A. punctimacula (Diptera: Culicidae) in coastal and highland Ecuador

Larval habitat for three highland Anopheles species: Anopheles albimanus Wiedemann, Anopheles pseudopunctipennis Theobald, and Anopheles punctimacula Dyar and Knab was related to human land uses, rivers, roads, and remotely sensed land cover classifications in the western Ecuadorian Andes. Of the five commonly observed human land uses, cattle pasture (n = 30) provided potentially suitable habitat for A. punctimacula and A. albimanus in less than 14% of sites, and was related in a principal components analysis (PCA) to the presence of macrophyte vegetation, greater surface area, clarity, and algae cover. Empty lots (n = 30) were related in the PCA to incident sunlight and provided potential habitat for A. pseudopunctipennis and A. albimanus in less than 14% of sites. The other land uses surveyed (banana, sugarcane, and mixed tree plantations; n = 28, 21, 25, respectively) provided very little standing water that could potentially be used for larval habitat. River edges and eddies (n = 41) were associated with greater clarity, depth, temperature, and algae cover, which provide potentially suitable habitat for A. albimanus in 58% of sites and A. pseudopunctipennis in 29% of sites. Road-associated water bodies (n = 38) provided potential habitat for A. punctimacula in 44% of sites and A. albimanus in 26% of sites surveyed. Species collection localities were compared to land cover classifications using Geographic Information Systems software. All three mosquito species were associated more often with the category “closed/open broadleaved evergreen and/or semi-deciduous forests” than expected (P ≤ 0.01 in all cases), given such a habitat’s abundance. This study provides evidence that specific human land uses create habitat for potential malaria vectors in highland regions of the Andes.

Unpacking Pieces of a Puzzle: Understanding Obesity-Related Health Risk through Lifestyle Behaviours and Well-Being

The primary objective of this non-experimental study was to examine the differences based on obesity-related health risk in terms of physical activity, sedentary behaviour and well-being in adults. Participants (N = 50; Mage = 38.50, SDage = 14.21) were asked to wear a SenseWear Armband (SWA) across a seven day monitoring period followed by a questionnaire package. Using the National Institute of Health’s (1998) criteria, participants were classified as either least, increased, or high risk based on waist circumference and Body Mass Index scores. Differences between these classifications were found in the amount of time spent in active energy expenditure for bouts of ten minutes or more (p = .002); specifically between least and high risk (p < .05). No other differences (p > .05) emerged. Participants’ also perceived the SWA as a practical and worthwhile device. Overall, these findings provide practical applications and future directions for health promotional research.
