The South Carolina coastal zone is among the fastest growing areas in the U.S., and population epicenters are marked by dense brackish water pond (lagoon) coverage associated with housing complexes and golf courses. Surveillance efforts in 2001–2002 documented the widespread occurrence of several types of potentially or measurably toxic harmful algal blooms (HABs) in these ponds. These man-made retention ponds were constructed in order to serve as a buffer between developed areas and open estuaries or for aesthetic reasons. However, the combination of restricted tidal flow and nutrient and/or contaminant deposition creates a stimulatory environment for potential HAB formation. These discoveries introduce the need to consider mitigation measures to existing ponds and HAB preventive strategies for future pond construction. 相似文献

Recent projects on international instrument development have produced a wide array of health indicators that may be used for
cross-cultural field-testing, however more information on their cross-cultural performance in relation to health determinants
is necessary. The current study approaches one step for international conceptual validation by analysing the association between
various health determinants and different types of health outcomes (mental health, quality of life) across a range of countries
or geographical areas. The current study is based on the EUROHIS project that has been conducted in a sample of 4849 adults
across 10 European countries. Results highlight that interactions between health determinants with subjective mental health,
general health and quality of life (QoL) differ between Western European countries, Eastern European countries and the Newly
Associated States as well as Israel. Using a MIMIC model approach, we were able to show that the impact of each of the sociodemographic
variables cannot be interpreted on the basis of its single loading but only seeing the interacting with other indicators.
Future studies should include sociodemographics in MIMIC models in each latent factor before carrying out regressions on a
larger scale. Future investigations will require larger and representative samples to (a) test models on latent factors of
mental health and QoL and (b) on the basis of these findings test overall structural models across countries. 相似文献

Aggregate population and economic growth correlations: The role of the components of demographic change 总被引:2,自引:0,他引:2
The results of recent correlations showing a negative impact of population growth on economic development in cross-country data for the 1980s, versus “nonsignificant” correlations widely found for the 1960s and 1970s, are examined with contemporaneous and lagged components of demographic change, convergence-type economic modeling, and several statistical frameworks. The separate impacts of births and deaths are found to be notable but offsetting in the earlier periods. In contrast, the short-run costs (benefits) of births (mortality reduction) increase (decrease) significantly in the 1980s, and the favorable labor-force impacts of past births are not fully offsetting. 相似文献

Among others, the term “problem” plays a major role in the various attempts to characterize interdisciplinarity or transdisciplinarity,
as used synonymously in this paper. Interdisciplinarity (ID) is regarded as “problem solving among science, technology and
society” and as “problem orientation beyond disciplinary constraints” (cf. Frodeman et al.: The Oxford Handbook of Interdisciplinarity.
Oxford University Press, Oxford, 2010). The point of departure of this paper is that the discourse and practice of ID have problems with the “problem”. The objective
here is to shed some light on the vague notion of “problem” in order to advocate a specific type of interdisciplinarity: problem-oriented interdisciplinarity. The outline is as follows: Taking an ex negativo approach, I will show what problem-oriented ID does not mean. Using references to well-established distinctions in philosophy of science, I will show three other types of ID that
should not be placed under the umbrella term “problem-oriented ID”: object-oriented ID (“ontology”), theory-oriented ID (epistemology),
and method-oriented ID (methodology). Different philosophical thought traditions can be related to these distinguishable meanings.
I will then clarify the notion of “problem” by looking at three systematic elements: an undesired (initial) state, a desired
(goal) state, and the barriers in getting from the one to the other. These three elements include three related kinds of knowledge:
systems, target, and transformation knowledge. This paper elaborates further methodological and epistemological elements of
problem-oriented ID. It concludes by stressing that problem-oriented ID is the most needed as well as the most challenging
type of ID. 相似文献

Abstract Burnout patients often report deficits in cognitive control, and there is a need to understand the processes involved. Drawing on recent findings, we hypothesized that emotional exhaustion and task-related demands on executive control would interact in predicting performance in tasks requiring the updating and monitoring of working memory as well as the inhibition of prepotent (dominant or automatic) responses. In accordance with recent conceptualizations of burnout, we focused on emotional exhaustion as the core symptom of burnout. The sample comprised 81 employees recruited from nursing homes for elderly care in Germany, who participated in a laboratory study involving cognitive tasks. Based on a median split, participants were divided into two groups: those with high burnout and those with low burnout. In line with our hypotheses, the high exhaustion participants performed less well than those with low exhaustion only when tasks put high demands on their executive control. As predicted, high levels of emotional exhaustion were associated with more errors and longer reaction times when demands on executive control were high, whereas no performance differences were found when both tasks put low demands on executive control. The implications for practice are discussed. 相似文献

Third-generation prospect theory 总被引:1,自引:0,他引:1
We present a new theory of decision under uncertainty: third-generation prospect theory (PT3). This retains the predictive power of previous versions of prospect theory, but extends that theory by allowing reference
points to be uncertain while decision weights are specified in a rank-dependent way. We show that PT3 preferences respect a state-conditional form of stochastic dominance. The theory predicts the observed tendency for willingness-to-accept
valuations of lotteries to be greater than willingness-to-pay valuations. When PT3 is made operational by using simple functional forms with parameter values derived from existing experimental evidence, it
predicts observed patterns of the preference reversal phenomenon.

Evolution of recent economic-demographic modeling: A synthesis 总被引:2,自引:1,他引:1
This paper develops a flexible framework for modeling population's role in economic growth by assessing and extending a rendering
suggested by several Harvard economists. Our framework includes a ``productivity' model explaining output-per-worker growth
and a ``translation' model translating that growth into per-capita terms. We specify a core economic model and several ``enriched'
demographic variants that include dependency, size, and density. Regressions using a cross-country panel spanning the period
1960-1995 reveal that combined impacts of demographic change have accounted for approximately 20% of per capita output growth
impacts, with larger shares in Asia and Europe.
An earlier draft of this paper was presented at a conference on ``Population Change, Labor Market Transition and Economic
Development in Asia,' Institute of Economics, Academia Sinica, Taipei, Taiwan, 6–9 December 2002. A pre-publication version
of this paper will be presented at a joint conference (by COE/JEPA) entitled ``Towards a new economic paradigm: Declining
population growth, labor market transition and economic development under globalization,' held at the Awaji Yumebutai International
Conference Center, Kobe, Japan, 17–19 December 2005. We have benefited from comments by Michelle Connolly, Andrew Mason, Pietro

There are factors inherent in the developmental process that make brief therapy a particularly viable intervention for infants, children, adolescents and young adults. A more explicit examination of developmental principles can provide a foundation for better understanding the potential and the efficacy of brief psychotherapy for patients in these age ranges. A case example illustrates these ideas.Clinical Social Worker, Student Counseling and Resource Service, University of Chicago; and in private practice in Chicago. 相似文献
