THE CURRENTS BENEATH THE “RISING TIDE” OF SCHOOL CHOICE: AN ANALYSIS OF STUDENT ENROLLMENT FLOWS IN THE CHICAGO PUBLIC SCHOOLS

Existing research highlights that families face geographic, social, and psychological constraints that may limit the extent to which competition can take hold in school choice programs. In this paper, we address the implications of such findings by creating a network of student flows from 11 cohorts of eighth‐grade students in the Chicago Public Schools (CPS). We applied a custom algorithm to group together schools with similar sending and receiving patterns, and calculated the difference in mean achievement between a student's attended and assigned high schools. For all identified school groupings, we found that the students were on average moving to higher achieving schools. We also found that the movement toward higher achieving schools of the top achievement quartile of students was over twice as large as that of the bottom quartile, but that the flows of both the highest and lowest achieving student quartiles were toward higher achieving destinations. Our results suggest that student movements in CPS between the years of 2001 to 2005 were consistent with creating market pressure for improvement as well as increasing segregation by achievement. However, further research into how schools responded to those movements is required to make inferences about the level or consequences of competition generated by choice‐related reforms during that time.     

Caustic Ingestion—A Forensic Overview

The ingestion of corrosive substances may produce severe burns to the upper aerodigestive tract and stomach, particularly if the pH is greater than 12 or less than two. There is a biphasic age grouping with adult cases most often involving self‐harm and pediatric cases accidental ingestion. Three cases are reported to demonstrate characteristic features following the ingestion of potassium hydroxide, glacial acetic acid and Lysol^®, respectively. All deaths were due to the effects of caustic burns to the upper aerodigestive tract, esophagus and stomach with perforation and/or hemorrhage. The extent of injuries in these cases depends on the nature, amount, and concentration of the agent and on the exposure time. A point to note at autopsy is that tissue damage may also occur from postmortem exposure. Typical injuries involve perioral, limb, and trunk burns, with extensive aerodigestive liquefactive/coagulative necrosis causing hemorrhage and perforation.     

Indigenous NGOs and refugee assistance

Although well placed to render assistance to refugees, indigenous NGOs usually play only a marginal role, compared with the Northern NGOs which dominate most humanitarian aid programmes. The unbalanced power relations between Northern agencies and donors and Southern NGOs in the delivery of refugee assistance are reviewed. Using data from the assistance programmes for Mozambican refugees in Malawi and Zimbabwe, the strategies and conditions by which some indigenous NGOs successfully challenged this prevailing situation are examined. Factors considered to be significant are institution building; diversifying the donor-base; project design and development; and the skills and expertise of field directors. The broader applicability of these experiences is considered.     

Delegation as a Source of Law

The status of delegation as a strictly institutionalized source of law is controversial. In this article, we examine some instances of delegation, in order to explore their claim to be independent and strictly institutionalized sources of law. We consider primarily the instances of labour arbitration and of mediation. Our conclusion is that there is no straightforward answer in either instance to the question whether they constitute sources of law, although the claim of arbitration is strong and that of mediation is weak. We argue that the controversial character of delegation as a source of law is therefore to be expected, given its ambivalent character, and that in exploring the reasons for this ambivalence much can be learnt about the concept of a strictly institutionalized source of law.     

Sociological interpretations of legal development

This paper seeks to outline some ways in which sociological inquiry has helped to interpret general processes of legal development. It comments on a few aspects of a vast subject. Furthermore, it was commissioned in a specific context of debate: as part of an agenda of discussion of the relative merits and potential of sociological and economic analyses of law. Hence, to provide a setting for what I try to argue about the character and value of sociological interpretations of legal change, it seems appropriate to preface those arguments with some general ideas about the nature of sociological inquiries in legal contexts and about perceived contrasts between the orientation of these inquiries and what I take to be certain orientations in economic analysis of law. Accordingly this paper is in two parts. The first offers a few prefatory remarks on the character of theoretically guided sociological inquiries about law (sociology of law). The second discusses various kinds of interpretation of legal development, which have been offered from the perspectives of sociology of law.
