See you in Geneva? Democracy, the Rule of Law and the WTO (Working Paper 16)

This paper is a constructivist attempt to understand a global political space where states as actors (the traditional domain of international relations theory and international law) are joined by international organizations, firms, NGOs, and others. Today we know that many supposedly private or international orders (meaning sources of order other than the central institutions of the territorial state) are engaged in the regulation of large domains of collective life in a world where the sources of power are multiple, sovereignties are overlapping, and anarchy is meaningless. The paper begins with an attempt, discussed in the first section, to sort out what the rule of law might mean in the context of the WTO, where we soon see that it can only be understood by also considering the meaning of Administrative Law. Much of the debate about rule of law depends on positivist and centralist theories of “law,” whose inadequacy for my purposes leads, in the second section, to a discussion of legal pluralism and implicit law in legal theory. These approaches offer an alternative theoretical framework that respects the role of the state while not seeing it as the only source of normativity. The third section looks directly at WTO law and dispute settlement. I tr y to show that the sources and interpretations of law in the WTO and the trading system cannot be reduced to the Dispute Settlement Body. I conclude in the fourth section with some suggestions on how a WTO rule of law could be understood as democratic.

(MIS)PERCEIVED DRINKING NORMS AND HAZARDOUS DRINKING BEHAVIOURS IN UNIVERSITY FIRST-YEAR UNDERGRADUATE STUDENTS AND THE EFFECTS OF GENDER

Purpose: Across Canada, undergraduate university students are one of the highest alcohol-consuming populations. Many students engage in hazardous drinking and are at risk for negative health and social consequences. Social Norms Theory suggests that students’ overestimation of drinking norms can result in an increase in their drinking behaviour. As of yet, none of the literature addresses the possible link between drinking norm (mis)perception and hazardous drinking in a Canadian undergraduate context. This is the first Canadian study to examine this potential association in first-year undergraduate students across multiple universities using gender as an effect modifier. Methods: Using data collected by the Caring Campus Project, for 2347 first-year students from three Canadian universities, I evaluated the prevalence of drinking norm misperceptions by site and gender. Using multiple-logistic regression models, I analyzed the relationship between misperceived drinking norms and hazardous drinking behaviours (assessed via AUDIT-C). Results: The proportion of students who overestimated drinking and binge drinking frequency norms varied by site and gender. There was a positive relationship between overestimated drinking/ binge drinking frequency norms and hazardous drinking, modified by gender. Controlling for living arrangement and site, the odds of female students being hazardous drinkers increased by a factor of 2.27 (CI: 1.73-2.99) when the drinking frequency norm was overestimated. A non-significant association was found for male students. Among female students, when living arrangement and site were controlled, the odds of being a hazardous drinker were 1.83 (0.84-3.95) and 2.69 (1.24-5.83) times greater when the drinking frequency norm was perceived at “2-4 times per month” and “2 or more times per week”, respectively. Among male students, when living arrangement, previous residence and site were controlled, the odds of being a hazardous drinker were 4.03 (2.62-6.19) and 8.54 (5.41-13.49) times greater when the binge drinking frequency norm was perceived at “2-4 times per month” and “2 or more times per week”, respectively. Conclusion: This novel study enhances the understanding of the association between (mis)perceived drinking norms and drinking behaviours in Canadian undergraduate students. The demonstrated importance of gender and site provides a strong impetus for Canadian universities to develop targeted alcohol reduction interventions.

RE-MEANING THE SACRED: COLONIAL DAMAGE AND INDIGENOUS COSMOLOGIES

Indigenous ways of knowing are dependent on an inheriting process both amongst humans and between human and non-human being. These multi-relationships cross material and immaterial borders as sites of knowledge production. This manuscript will interrogate how three particular Indigenous cosmological relationships have been purposefully re-meaninged by colonial institutions: 1) How Anishinaabe and Haudenosaunee origin stories have been abstracted into a distinctive epistemological versus ontological site; 2) How Anishnaabe spirit worlds are impacted by colonial relations, and how state institutions benefit from the re-meaning of these worlds; and 3) How Indigenous sovereignty in Canada is imagined from a statist perspective, and how these polices have re-meaninged the sacred relationships within a cosmological understanding of Haudenosaunee governance. The re-meaning of sacredly-held Indigenous relationships is both accelerated by, and contributes to, a practice of reducing upon Indigenous and non-human societies. Throughout expressions of colonialism on Indigenous territories (the academy, the state, Indian policy), Indigenous knowledge is consistently either dismissed or appropriated. This reduction of Indigenous knowledge continues to bolster functions of the state as related to the elimination of the “Indian Problem” via reducing the “Indian” to an adaptive subject.

Linear Hyperspectral Unmixing Using L0-norm Approximations and Nonnegative Matrix Factorization

Spectral unmixing (SU) is a technique to characterize mixed pixels of the hyperspectral images measured by remote sensors. Most of the existing spectral unmixing algorithms are developed using the linear mixing models. Since the number of endmembers/materials present at each mixed pixel is normally scanty compared with the number of total endmembers (the dimension of spectral library), the problem becomes sparse. This thesis introduces sparse hyperspectral unmixing methods for the linear mixing model through two different scenarios. In the first scenario, the library of spectral signatures is assumed to be known and the main problem is to find the minimum number of endmembers under a reasonable small approximation error. Mathematically, the corresponding problem is called the $\ell_0$-norm problem which is NP-hard problem. Our main study for the first part of thesis is to find more accurate and reliable approximations of $\ell_0$-norm term and propose sparse unmixing methods via such approximations. The resulting methods are shown considerable improvements to reconstruct the fractional abundances of endmembers in comparison with state-of-the-art methods such as having lower reconstruction errors. In the second part of the thesis, the first scenario (i.e., dictionary-aided semiblind unmixing scheme) will be generalized as the blind unmixing scenario that the library of spectral signatures is also estimated. We apply the nonnegative matrix factorization (NMF) method for proposing new unmixing methods due to its noticeable supports such as considering the nonnegativity constraints of two decomposed matrices. Furthermore, we introduce new cost functions through some statistical and physical features of spectral signatures of materials (SSoM) and hyperspectral pixels such as the collaborative property of hyperspectral pixels and the mathematical representation of the concentrated energy of SSoM for the first few subbands. Finally, we introduce sparse unmixing methods for the blind scenario and evaluate the efficiency of the proposed methods via simulations over synthetic and real hyperspectral data sets. The results illustrate considerable enhancements to estimate the spectral library of materials and their fractional abundances such as smaller values of spectral angle distance (SAD) and abundance angle distance (AAD) as well.
