Regulation of immigration in 1993: pieces of the European Community jig-saw puzzle

"This contribution will try, on one hand, to take stock of the past [European Community] policy on migration and on the other hand to provide the basic elements which are shaping a future potentially common (or partly common) policy, carried out either through intergovernmental cooperation or community legislation or both." Pertinent treaties and legislation are also described.     

On the quality of reinterview data with application to the Current Population Survey

"The [U.S.] Current Population Survey (CPS) reinterview sample consists of two subsamples: (a) a sample of CPS households is reinterviewed and the discrepancies between the reinterview responses and the original interview responses are reconciled for the purpose of obtaining more accurate responses..., and (b) a sample of CPS households, nonoverlapping with sample (a), is reinterviewed 'independently' of the original interview for the purpose of estimating simple response variance (SRV). In this article a model and estimation procedure are proposed for obtaining estimates of SRV from subsample (a) as well as the customary estimates of SRV from subsample (b).... Data from the CPS reinterview program for both subsamples (a) and (b) are analyzed both (1) to illustrate the methodology and (2) to check the validity of the CPS reinterview data. Our results indicate that data from subsample (a) are not consistent with the data from subsample (b) and provide convincing evidence that errors in subsample (a) are the source of the inconsistency."     

Policy instruments for reducing toxic releases. The effectiveness of state information and enforcement actions

This article analyzes the extent to which different policy instruments explain toxic reductions among the states. Data from the Toxics Release Inventory (TRI) and other sources are used to assess the effect of various policy instruments, while holding economic factors constant. State TRI information programs, enforcement action, and direct regulation all matter in reducing toxic releases. Interestingly, the informational tool seems to matter more than both authoritative tools. The findings also support the idea that the interaction of policy instruments as well as the match between policy tools and policy context may account for a portion of the results.     

Modelling human immunodeficiency virus infection and acquired immune deficiency syndrome cases in Scotland: data sources,prior information and Bayesian estimation

The paper describes the methodology developed to carry out predictions of the acquired immune deficiency syndrome (AIDS) epidemic in Scotland. Information on the human immunodeficiency virus (HIV) epidemic comes from formal case reports of AIDS cases and HIV positive tests, reports from surveillance schemes and from special studies. These sources of information, up to the end of 1994, are reviewed. Prior information on aspects of HIV disease is available from various published and unpublished sources. A simple model of the HIV epidemic in Scotland is proposed and the information is summarized in terms of this model. Bayesian methodology, using Markov chain Monte Carlo methods, is described and used to predict future cases of AIDS in Scotland and people who will be living with AIDS in the years 1995–1999.     

Albanian and Polish undocumented workers in Greece: a comparative analysis

"This article deals with the migration of undocumented workers from Albania and Poland to Greece. Its underlying assumption is that migration from the former post-communist countries to Greece is not a homogeneous phenomenon, thus allowing for a distinction and comparison between the migration waves from Poland and Albania to Greece. The article shows that economic migration from Albania and Poland to Greece is primarily an economically triggered phenomenon which results from both individual rational choices and social, structural settings, and which verifies a general tendency of mass flows, characteristic of the era of disorganized capitalism."

Formatting and presenting quality data to medical staffs and hospital boards

A host of historical and practical precedents have made hospitals responsible for the quality of care rendered within their facilities. The medical staff and the board of trustees share in this responsibility. Increasing demands for demonstrative evidence of the quality of care in an institution have made the process data-based. There is no substitute for specific data on the performance of both the hospital and its providers in the delivery of care. The trick, however, is in presenting this information to the medical staff and the board in a fashion that will be understandable and that will still maintain confidentiality of provider and patient. The authors offer a presentation system that has met with success in their community hospital.     

Home surgical recovery program proves value

The evidence is overwhelming that sharp reductions in health care costs can be achieved by reducing or eliminating reliance on expensive hospital care. In surgery, this is not always possible. However, significant savings can be achieved through reducing the length of time that a surgery patient must spend in the hospital. In outpatient surgery, the hospital stay is reduced to a single day. In this article, the authors describe a home surgical recovery program that has had great success in reducing hospital stays for even more complicated surgical procedures, frequently matching the achievements of outpatient surgery programs.     

How stock dependent flow rates may imply chaos in educational planning

"The aim of the present paper is to illustrate how extremely complex patterns may be generated in a simple model of educational planning. In particular, we will show that certain dependencies of the flow rates on the teacher/student ratio imply nonlinearities which are substantial enough to generate erratic behaviour of the time paths. The main message is that chaos in educational planning may result from assumptions which are indeed qualitatively realistic but which are quantitatively exaggerated." (SUMMARY IN FRE)     

Older Motherhood and the Changing Life Course in the Era of Assisted Reproductive Technologies

Midlife, once a focus of particular interest to gerontologists because of its implications for later life, has recently received little attention. But as new reproductive technologies have expanded in the United States, motherhood is occurring at older ages. While older motherhood is not a new social practice, what is unique is that an increasing number of women are becoming pregnant through technological means, often for the first time, at the end of their reproductive cycle. These women can be understood as part of a new middle age, engaging in new life course possibilities that respond to changing social, cultural, physical, and economic realities, and potentially extending much later in the life course. Drawing on interviews with 79 couples, we utilize symbolic interactionist conceptualizations of identity and stigma to consider how women negotiate the shifting social identities associated with older motherhood. We conclude that older motherhood will be one phenomenon contributing to an enduring change in views of what constitutes old age, and that it will be seen as occurring much later in the life course.
