Semantic analysis of natural language processing in a study of nurse mobility in the Northern Territory,Australia

In lieu of diverse consequences in the demand and supply of health care professionals such as nurses and midwives in Australia and the world, a firm understanding of the characteristics of staff mobility and the factors influencing their retention could lead to achieving enhanced service delivery, greater job satisfaction, and the establishment of a more stable and robust workforce. The research reported in this paper attempts to shed light on qualitative aspects of mobility in health care professional staff in the Northern Territory of Australia. It builds upon an existing survey study of the quantitative factors that determine why nurses and midwives come to the Northern Territory, why some stay and why many leave, by analysing additional qualitative textual responses of participants using semantic network approaches to natural language processing. Our results illustrate the methodological and policy significance of semantic approaches to knowledge acquisition and representation, especially in complementing findings of traditional survey analysis techniques, and in analysing the broader social settings, effects and consequences of staff retention and mobility.     

The Human Capital Model of Selection and Immigrant Economic Outcomes

This article examines the trends in the economic advantage that highly educated immigrants hold over less educated immigrants in Canada, focusing on the differences between short‐run and longer‐run outcomes. Using data from the Longitudinal Immigration Database covering the period from the 1980s to the 2000s, this study finds that the relative entry earnings advantage that higher education provides to new immigrants has decreased dramatically over the last 30 years. However, university‐educated immigrants had a much steeper earnings trajectory than immigrants with trades or a high school education. The earnings advantage among highly educated immigrants increases significantly with time spent in Canada. This pattern is observed for virtually all immigrant classes and arrival cohorts. The results suggest that short‐run economic outcomes of immigrants are not good predictors of longer‐run results, at least by educational attainment. The implications of these findings for immigration selection policy are discussed in the conclusion.     

Poverty Dynamics among Recent Immigrants to Canada1

This paper examines two issues: (1) poverty dynamics among successive cohorts of entering immigrants to Canada, and (2) whether rising educational attainment and increasing share in the “skilled” class since the early 1990s has resulted in improvements in poverty entry, exit, and chronic poverty. The entry to poverty is very high during the first year in Canada, but low in subsequent years. The dramatic move toward more labor‐market friendly characteristics of entering immigrants had only a very small effect on poverty outcomes, in part because the relative advantage of holding a degree diminished, and “skilled economic” class immigrants were more likely to enter poverty than their “family” class counterparts.     

Newcomb's Hidden Regress

Newcomb's problem supposedly involves your choosing one or else two boxes in circumstances in which a predictor has made a prediction of how many boxes you will choose. We argue that the circumstances which allegedly define Newcomb's problem generate a previously unnoticed regress which shows that Newcomb's problem is insoluble because it is ill-formed. Those who favor, as we do, a ``no-box' reply to Newcomb's problem typically claim either that the problem's solution is underdetermined or else that it is overdetermined. We are no-boxers of the first kind, but the underdetermination we identify is more radical than any previously identified: it blocks the very set-up of the problem and not just potential solutions to the problem once it has been set up. The defect is subtle, but it cripples every genuine version of the problem, regardless of variations in such things as the predictor's degree of reliability, the basis on which the prediction is made, or the amount of money in each box. The regress shows that, surprisingly enough, no one can understand Newcomb's problem, and so no one can possibly solve it.     

Crisis Communication Post Katrina: What are we Learning?

Hurricane Katrina and post-Katrina audits are an on-going project for public affairs scholarship. Much has been written but critical frameworks of analysis are minimal. Crisis communication taxonomies are rich and fruitful in understanding the framing of calamitous events. In revisiting a previous mapping of crisis communication vulnerability points in the Katrina tragedy, the authors provide a further “vulnerability audit” of crisis-communication capabilities within a changing political/administrative ontology—one pointing to the privatization of crises/disasters within the Neo-liberal state. Lessons about crisis communication according to the earlier four conceptual lenses (Garnett and Kouzmin 2007) are supported by more recent developments and scholarship.     

Multi‐Case Review of the Application of the Precautionary Principle in European Union Law and Case Law

The precautionary principle was formulated to provide a basis for political action to protect the environment from potentially severe or irreversible harm in circumstances of scientific uncertainty that prevent a full risk or cost‐benefit analysis. It underpins environmental law in the European Union and has been extended to include public health and consumer safety. The aim of this study was to examine how the precautionary principle has been interpreted and subsequently applied in practice, whether these applications were consistent, and whether they followed the guidance from the Commission. A review of the literature was used to develop a framework for analysis, based on three attributes: severity of potential harm, standard of evidence (or degree of uncertainty), and nature of the regulatory action. This was used to examine 15 pieces of legislation or judicial decisions. The decision whether or not to apply the precautionary principle appears to be poorly defined, with ambiguities inherent in determining what level of uncertainty and significance of hazard justifies invoking it. The cases reviewed suggest that the Commission's guidance was not followed consistently in forming legislation, although judicial decisions tended to be more consistent and to follow the guidance by requiring plausible evidence of potential hazard in order to invoke precaution.     

Assessing the Potential Impact of the HIV-1 Epidemic on Orphanhood and the Demographic Structure of Populations in sub-Saharan Africa

Much of the debate on the demographic consequences of the HIV epidemic in sub-Saharan Africa has so far centred around the plausibility of population declines in areas where unprecendently high rates of population growth have recently been in evidence. In this article, the authors use a mathematical model, which combines epidemiological and demographic processes, to illustrate how, under a broad range of impacts on population growth, major changes in demographic features, such as the extent of orphanhood within populations, are likely to occur. At the same time, HIV epidemics are liable to cause significant shifts in the age and sex composition of affected populations, which may have important implications for the ways in which they are best able to cope with the increases in orphanhood, as well as those in infant, early childhood and adult mortality.     

The study of war in American sociology: An analysis of selected journals, 1936 to 1984

In an analysis of articles in theAmerican Journal of Sociology theAmerican Sociological Review, andSocial Forces at six-year intervals between 1936 and 1984 it was found that the topic of war was not often examined, especially in more recent decades. The most unexpected finding was that there were proportionately no more articles on war in selected European journals than in the top three American journals. It was concluded that war is not perceived as an important research topic in American sociology, as reflected in major sociology journals. His dissertation will deal with conditions for cooperation between adversaries during war.     

Careers Open to Talent: Educational Credentials,Cultural Talent,and Skilled Employment1

In the status attainment and social mobility literatures, “talent” is often conceptualized as educational attainment or mental ability. We adapt Bourdieu’s notion of embodied cultural capital and Goffman’s notion of “staging a character” into another dimension of talent, what we call “cultural talent,” and hypothesize that an ability to wield cultural talent in hiring or promotion scenarios facilitates attainment of skilled, complex jobs. Bivariate analyses and multiple regression modeling performed on data from an original survey show that educational credentials and cultural talent both predict occupational skill and complexity.
