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

Infrared thermography: A non-invasive window into thermal physiology

Infrared thermography is a non-invasive technique that measures mid to long-wave infrared radiation emanating from all objects and converts this to temperature. As an imaging technique, the value of modern infrared thermography is its ability to produce a digitized image or high speed video rendering a thermal map of the scene in false colour. Since temperature is an important environmental parameter influencing animal physiology and metabolic heat production an energetically expensive process, measuring temperature and energy exchange in animals is critical to understanding physiology, especially under field conditions. As a non-contact approach, infrared thermography provides a non-invasive complement to physiological data gathering. One caveat, however, is that only surface temperatures are measured, which guides much research to those thermal events occurring at the skin and insulating regions of the body. As an imaging technique, infrared thermal imaging is also subject to certain uncertainties that require physical modeling, which is typically done via built-in software approaches. Infrared thermal imaging has enabled different insights into the comparative physiology of phenomena ranging from thermogenesis, peripheral blood flow adjustments, evaporative cooling, and to respiratory physiology. In this review, I provide background and guidelines for the use of thermal imaging, primarily aimed at field physiologists and biologists interested in thermal biology. I also discuss some of the better known approaches and discoveries revealed from using thermal imaging with the objective of encouraging more quantitative assessment.

Isolation and characterization of genomic DNA sequences that enhance the stability of plasmid DNA in mammalian cells /

The ease of production and manipulation has made plasmid DNA a prime target for its use in gene transfer technologies such as gene therapy and DNA vaccines. The major drawback of plasmid however is its stability within mammalian cells. Plasmid DNA is usually lost by cellular mechanisms or as a result of mitosis by simple dilution. This study set out to search for mammalian genomic DNA sequences that would enhance the stability of plasmid DNA in mammalian cells.Creating a plasmid based genomic DNA library, we were able to screen the human genome by transfecting the library into Human Embryonic Kidney (HEK 293) Cells. Cells that contained plasmid DNA were selected, using G418 for 14 days. The resulting population was then screened for the presence of biologically active plasmid DNA using the process of transformation as a detector.A commercially available plasmid DNA isolation kit was modified to extract plasmid DNA from mammalian cells. The standardized protocol had a detection limit of -0.6 plasmids per cell in one million cells. This allowed for the detection of 45 plasmids that were maintained for 32 days in the HEK 293 cells. Sequencing of selected inserts revealed a significantly higher thymine content in comparison to the human genome. Sequences with high A/T content have been associated with Scaffold/Matrix Attachment Region (S/MAR) sequences in mammalian cells. Therefore, association with the nuclear matrix might be required for the stability of plasmids in mammalian cells.

Intracellular antioxidant and DNA repair enzymes as correlates of stress resistance and longevity in vertebrates

In animals, both stress resistance and longevity appear to be influenced by the insulin/insulin-like growth factor-l signaling (lIS) pathway, the basic organization of which is highly conserved from invertebrates to vertebrates. Reduced lIS or genetic disruption of the lIS pathway leads to the activation of forkhead box transcription factors, which is thought to upregulate the expression of genes involved in enhancing stress resistance, including perhaps key antioxidant enzymes as well as DNA repair enzymes. Enhanced antioxidant and DNA repair capacities may underlie the enhanced cellular stress resistance observed in long-lived animals, however little data is available that directly supports this idea. I used three. experimental approaches to test the association of intracellular antioxidant and DNA base excision repair (BER) capacities with stress resistance and longevity: (1) a comparison of multiple vertebrate endotherm species of varying body masses and longevities; (2) a comparison of long-lived Snell dwarf mice and their normallittermates; and (3) a comparison of hypometabolic animals undergoing hibernation or estivation with their active counterparts. The activities of the five major intracellular antioxidant enzymes as well as the two rate-limiting enzymes in the BER pathway, apurininc/apyrimidinic (AP) endonuclease and polymerase ~, were measured. These measurements were performed in one or more of the following: (1) cultured dermal fibroblasts; (2) brain tissue; (3) heart tissue; (4) liver tissue. My results indicate that antioxidant enzymes are not universally upregulated in association with enhanced stress resistance and longevity. I also did not find that BER enzyme activity was positively correlated with longevity, in an inter-species context, though there was evidence for enhanced BER in long-lived Snell dwarf mice. Thus, while there were instances in which enhanced antioxidant and BER enzyme activities were associated with increased stress resistance and/or longevity, this was not universally the case, indicating that other mechanisms must be involved. These results suggest the need to re-examine existing 'oxidative stress' hypotheses of longevity and probe further into the molecular physiology of longevity to discover its mechanistic basis.

The Myth of Labour-Management Partnerships and the Risk to Labour: A CAMI Automotive Study

The purpose of this study is to examine and explore the level of risk that CAMI workers confront under their existing labour-management partnership arrangement. Risk is explored using two distinct categories, distributive and political. Distributive risk is expressed as tangibly substantive, reflecting the real terms and conditions of employment, and the changing social relations of production on the floor. The second type of risk is political and is concerned with the effects that labour-management partnerships have on the displacement of unions as legitimate agents of/for workers within the workplace. Data was collected using three methods; content analysis, cross-sectional survey and focus group interviews. The study revealed that CAMI workers are exposed to both distributive and political risk under their current LMP arrangement.

The Political Economy of St. Catharines' Illicit Taxi Trade

The global restructuring of production has led to increasingly precarious working conditions around the world. Post-industrial work is characterized by poor working conditions, low wages, a lack of social protection and political representation and little job security. Unregulated forms of work that are defined as “irregular” or “illegal”, or in some cases “criminal,” are connected to sweeping transformations within the broader regulated (formal) economy. The connection between the formal and informal sectors can more accurately be described as co-optation and, as a subordinate integration of the informal to the formal. The city of St. Catharines within Niagara, along with much of Ontario’s industrial heartland, has been hard hit by deindustrialization. The rise of this illegal service is thus viewed against the backdrop of heavy economic restructuring, as opportunities for work in the manufacturing sector have become sparse. In addition, this research also explores the paradoxical co-optation of the growing illicit taxi economy and consequences for racialized and foreign credentialed labour in the taxi industry. The overall objective of this research is to explore the illicit cab industry as not only inseparable from the formal economy, but dialectically, how it is as an integrated and productive element of the public and private transportation industry. Furthermore the research examines what this co-optation means in the context of a labour market that is split by race.

Report of Directors to the Shareholders, 1970

The report reads: "The year 1970 saw many significant changes in our Company. Sales were higher than in any previous year showing an increase in gallons of 8.8% and in dollar volume of 9.7%. The new offices and warehouse are fully operational, the fermenters installed prior to vintage assisted in holding our labour costs to a reasonable level, and the use of liquid sugar proved very successful. We added two representatives to our sales staff during the year and direct contact with our customers will be intensified. Product development is continuing and the addition of new lines and better distribution will be receiving priority. Our venture in the product supply for Valley Rouge Wines of Manitoba will, we trust, increase our sales volume and assist in lowering our fixed overhead. Capital expenses in 1971 will continue at a high level. Our co-operation with the various Government departments in respect to pollution, will obligate our Company to install facilities to satisfy the strict requirements in this regard. Preparations must be made now to handle bulk harvested grapes, the addition of storage and fermenting capacity and the replacement of production equipment, will be under constant review, thus enabling us to maintain production and efficiency. With the continued dedicated service of our personnel and the support of all our Shareholders, we are confident the challenge will be met in 1971."
