Once More Unto The Breach: Confronting The Standard Of Review (Again) And The Imperative Of Correctness Review When Interpreting The Scope Of Refugee Protection, Gerald Heckman, Amar Khoday

Dalhousie Law Journal

The Supreme Court of Canada’s standard of review jurisprudence has been marked by the ascendancy of reasonableness as the presumptive standard of review of decisions involving an administrative tribunal’s interpretation and application of its home statute. To the extent that this approach would lead to the reasonableness review of administrative decision-makers’ interpretation of the scope and meaning of provisions of the Immigration and Refugee Protection Act that implement the basic human rights conferred in international conventions to which Canada is a party, it must be changed. Interpretations of the scope of the Refugee Convention and Convention Against Torture raise questions …

The Battle For The Wrong Mistake: Risk Salience In Canadian Refugee Status Decision-Making, Hilary Evans Cameron

Dalhousie Law Journal

Canadian refugee status adjudicators must choose between two opposing bodies of law, one of which resolves doubt in the claimant’s favour and the other at the claimant’s expense. How do they decide which to prefer? How do they decide whether it would be better to risk accepting an unfounded claim or to risk rejecting a well-founded one? This paper explores one potentially relevant factor: the salience of the harms that decision-makers associate with potential risk outcomes. A brief account of recent events in Canadian refugee law history, beginning with the refugee law reforms of former Conservative Immigration Minister Jason Kenney, …

Do The Means Change The Ends? Express Entry And Economic Immigration In Canada, Asha Kaushal

Dalhousie Law Journal

The relationship between economy and community is a constitutive tension in the Canadian immigration state. With the rise of the knowledge economy, Canada mediated this tension through the concept of human capital, internalized in the points system. Introduced in 2015, Express Entry transformed the landscape of economic immigration in Canada. Express Entry is an online permanent residence application system. In this article, I argue that Express Entry is more than a change in form and process; it is a change in substance that shifts Canada’s skilled immigration regime toward a neo-corporatist model. By shifting partial decision-making authority to the provinces …

Relationship Of Mastication Rate And Body Length In West Indian Manatees, Adam Weir

Honors Theses

This study investigates the intraspecific relationship between body length and chewing cycle duration (CCD) among West Indian manatees (Trichechus  manatus).  We recorded 18 captive manatees of varying body lengths consuming two food types.  Additionally, nine of these manatees were recorded on two separate occasions, six years apart, allowing us to control for individual variation to test whether CCD increases as the manatees grow.  CCD was determined from the recordings using Raven Pro 1.5 bioacoustic analysis software.  Food type (r=0.78, p=6.8x10-5, n=17) and body length (r=0.53, p=0.033, n=17) significantly affected CCD.  Manatees chew at a consistent rate, so it may be …

Determination Of Constructed Pavement Layer Thicknesses Using Nondestructive Testing (Ndt), Brad W. Rister, Jamie Creech, Kean H. Ashurst Jr.

Kentucky Transportation Center Research Report

Using nondestructive testing (NDT) to measure the thickness of pavement layers can improve the overall life of a new concrete and/or asphalt pavement. Conventional test methods require the extraction of a core from the pavement section to verify its thickness. Currently, two NDT technologies are commercially available which eliminate or reduce the need to core the existing pavement for thickness verification. The MIT-Scan-T2 (T2) utilizes magnetic pulse induction coupled with preset metal plates to obtain a thickness value. Measurements can be obtained quickly to an accuracy of +/– 2 mm. Ground Penetrating Radar (GPR) uses electromagnetic radiation to determine pavement …

Impact Of Fiber Nonlinearity On The Performance Of Mode Division Multiplexing Systems, Esraa K., Mohammed A., Jassim K. Hmood

Iraqi Journal of Computers, Communications, Control and Systems Engineering

in this paper, an analytical model is developed to estimate a nonlinear phase noise (NPN) due to Kerr fiber nonlinearity and its interaction with amplifier noise in mode division multiplexing (MDM) systems. Our analysis uses generalized coupled multimode nonlinear Schrödinger equations (MM- NLSE) that describe the propagation of the mode superimposing in the optical fiber. The nonlinear phase noise versus channel power and transmission distance is evaluated by implementing our analytical model for LP01, LP11a, and LP11b spatial modes. Each mode carries a 4-QAM signal at a symbol rate of 20 Gsymbol/s. The results reveal that LP11 mode has a …
