Counterexamples to a conjecture of Lemmermeyer

We produce infinitely many finite 2-groups that do not embed with index 2 in any group generated by involutions. This disproves a conjecture of Lemmermeyer and restricts the possible Galois groups of unramified 2-extensions, Galois over the rationals, of quadratic number fields

Improving Canada's Immigration Policy

As labour markets change, the question arises whether Canada’s immigration policy – and our “point system” in particular – is doing a good job of identifying potential immigrants who will fare well on arrival in Canada.economic growth and innovation, immigration point system, Canadian immigration policy

Wage-Employment Contracts: Global Results

This paper studies the efficient agreements about the dependence of workers' earnings on employment, when the employment level is controlled by firms. The firms ' superior information about profitability conditions is responsible for this form of contract governance. Under plausible assumptions, such agreements will cause employment to diverge from efficiency as a byproduct of their attempt to mitigate risk. It is shown that, if leisure is a normal good and firms are risk neutral, employment is always above the efficient level. Such a one-period implicit contracting model cannot, therefore, be used to "explain" unemployment as a rational byproduct of risk sharing between workers and a risk neutral firm under conditions of asymmetric information.

Impacts of the Point System and Immigration Policy Levers on Skill Characteristics of Canadian Immigrants

This paper examines how changes in immigration policy levers actually affect the skill characteristics of immigrant arrivals using a unique Canadian immigrant landings database. We first review the Canadian experience with a point system as part of its immigrant policy. Section III of the paper describes some overall patterns of immigrant arrivals since 1980. Section IV identifies some relevant hypotheses on the possible effects on immigrant skill characteristics of the total immigration rate, the point system weights and immigrant class weights. The "skill" admissions examined are level of education, age, and fluency in either English or French. Regressions are then used to test the hypotheses from Canadian landings data. It is found that (i) the larger the inflow rate of immigrants the lower the average skill level of the arrivals; (ii) increasing the proportion of skill-evaluated immigrants raises average skill levels; (iii) increasing point system weights on a specific skill dimension indeed has the intended effect of raising average skill levels in this dimension among arriving principal applicants; and (iv) increasing the proportion of skill-evaluated immigrants appears to have the strongest effects among the immigration policy levers.immigration policy, points system, Canadian immigration

What Social Workers Do: Implications for the Reclassification Debate

The reclassification trend is one of the most formidable issues facing American social work today. Social work\u27s vulnerability stemming from a general ambiquity about its distinct role and boundaries, competition from emerging helping occupations, and its debated professionalism is a major contributing factor. Often ignored in recent efforts to address reclassification is empirical evidence of social work\u27s distinct performance in the human services versus other occupational groups. In this article comparative research findings supporting social work\u27s unique performance are presented and their relevance for reclassification discussed

A Guide to Monetary Sanctions for Environment Violations by Federal Facilities

Many federal environmental statutes require compliance by federal agencies by providing waivers of sovereign immunity. This Article explores the availability of civil penalties against the United States through an analysis of three United States Supreme Court decisions, encompassing the Clean Water Act, the Resource Conservation and Recovery Act, and the Comprehensive Environmental Response, Compensation, and Liability Act. It reviews the holdings in these cases to determine the efficacy of the waiver of federal sovereign immunity in each of these statutes, and develops a framework for analyzing the waiver available under the Clean Air Act. Ultimately, this Article concludes that the Clean Air Act\u27s citizen suit provision is a viable, yet unused, basis to impose civil penalties against federal facilities

"Missing Me One Place Search Another": Three Previously Unpublished Walt Whitman Notebooks

Introduces and provides a transcription of Whitman\u27s previously unpublished "Glendale Notebook" and argues that its "absence from the Collected Writings calls into question the handling of the Feinberg-Whitman Collection" by earlier editors
