  2. The Role of Education on Disaster Preparedness: Case Study of 2012 Indian Ocean Earthquakes on Thailand's Andaman Coast

    Muttarak, Raya; Pothisiri , Wiraporn
    In this paper we investigate how well residents of the Andaman coast in Phang Nga province, Thailand, are prepared for earthquakes and tsunami. It is hypothesized that formal education can promote disaster preparedness because education enhances individual cognitive and learning skills, as well as access to information. A survey was conducted of 557 households in the areas that received tsunami warnings following the Indian Ocean earthquakes on 11 April 2012. Interviews were carried out during the period of numerous aftershocks, which put residents in the region on high alert. The respondents were asked what emergency preparedness measures they had taken following the 11 April earthquakes....

  3. Mortality compression in period life tables hides decompression in birth cohorts in low-mortality countries

    Ediev, Dalkhat
    The rapid increase in human longevity has raised important questions about what implications this development may have for the variability of age at death. Earlier studies have reported evidence of a historical trend towards mortality compression. However, the period life table model, commonly used to address mortality compression, produces a compressed picture of mortality as a built-in feature of the model. To overcome this limitation, we base our study on an examination of the durations of exposure, in years of age, of birth cohorts and period life tables to selected short ranges of the death rate observed at old age....

  4. Integrating uncertainty in time series population forecasts: An illustration using a simple projection model

    Abel, Guy; Bijak, Jakub; Forster, Jonathan J.; Raymer, James; Smith, Peter W.F.; Wong, Jackie S.T.
    BACKGROUND: Population forecasts are widely used for public policy purposes. Methods to quantify the uncertainty in forecasts tend to ignore model uncertainty and to be based on a single model. OBJECTIVE: In this paper, we use Bayesian time series models to obtain future population estimates with associated measures of uncertainty. The models are compared based on Bayesian posterior model probabilities, which are then used to provide model-averaged forecasts. METHODS: The focus is on a simple projection model with the historical data representing population change in England and Wales from 1841 to 2007. Bayesian forecasts to the year 2032 are obtained based on a range of models, including...

  5. Estimating global migration flow tables using place of birth data

    Abel, Guy
    BACKGROUND: International migration flow data often lack adequate measurements of volume, direction and completeness. These pitfalls limit empirical comparative studies of migration and cross national population projections to use net migration measures or inadequate data. OBJECTIVE: This paper aims to address these issues at a global level, presenting estimates of bilateral flow tables between 191 countries. METHODS: A methodology to estimate flow tables of migration transitions for the globe is illustrated in two parts. First, a methodology to derive flows from sequential stock tables is developed. Second, the methodology is applied to recently released World Bank migration stock tables between 1960 and 2000 (Özden et al....

  6. Kompetenzorientierung in der Berufsbildung. Ein Modellversuch im Spektrum zwischen Input-, Prozess- und Produktqualität

    Schopf, Christiane; Müllauer-Hager, Barbara
    Vor dem Hintergrund intensiver Qualitätsdiskussionen im österreichischen Bildungssystem unter dem Schlagwort "Kompetenzorientierung" wird in diesem Beitrag für berufsbildende höhere Schulen ein Konzept zur umfassenden, d. h. Input, Prozess und Produkt berücksichtigenden, Qualitätsentwicklung vorgeschlagen. Die Instrumente dieses Konzepts "KLEE" sind ein Kerncurriculum, eine Fallbeispiel-sammlung, eine Lernstandserhebung sowie eine Lehrer/innen-Fortbildung. Ziel dieses Beitrags ist es, die Auswahl dieser Instrumente zu begründen, die einzelnen Instrumente von ihrer Konzeption her zu beschreiben sowie daran anknüpfend am Beispiel der Handelsakademie, II. Jahrgang Betriebswirtschaft, konkret zu zeigen, wie diese Instrumente fachdidaktisch umgesetzt werden könnten. Im Rahmen eines Modellversuchs wurde das Konzept in 13 Wiener Handelsakademien ein...

  7. Intergenerational transmission of socioeconomic conditions in Austria in the context of European welfare regimes

    Schnetzer, Matthias; Altzinger, Wilfried
    This paper uses data from the European Union Statistics on Income and Living Conditions (EU-SILC) 2005 to analyze intergenerational income mobility in Austria compared to other European Union members. Applying various methodological approaches, the data reveal substantial differences in intergenerational income persistence across European welfare regimes. The results show that income class rigidities are much less evident in Nordic countries compared to other European countries including Austria.

  8. Very long range global Population Scenarios to 2300 and the Implications of Sustained low Fertility

    Lutz, Wolfgang; Basten, Stuart; Scherbov, Sergei
    Depending on whether the global level of fertility is assumed to converge to the current European TFR (~1.5) or that of Southeast Asia or Central America (~2.5), global population will either decline to 2.3-2.9 billion by 2200 or increase to 33-37 billion, if mortality continues to decline. Furthermore, sizeable human populations exist when the 'voluntary chosen' ideal family size is heavily concentrated around one child per woman with TFRs as low as 0.6-0.8. However, the UN population projections to 2300 use a much narrower band of possible future TFRs. If the two-child norm is not necessarily the end-point transition, what...

  9. How do firm characteristics affect behavioural additionalities of public R&D subsidies? Evidence for the Austrian transport sector

    Wanzenböck, Iris; Scherngell, Thomas; Fischer, Manfred M.
    Interest of STI policies to influence the innovation behaviour of firms has been increased considerably. This gives rise to the notion of behavioural additionality, broadening traditional evaluation concepts of input and output additionality. Though there is empirical work measuring behavioural additionalities, we know little about what role distinct firm characteristics play for their occurrence. The objective is to estimate how distinct firm characteristics influence the realisation of behavioural additionalities. We use survey data on 155 firms, considering the behavioural additionalities stimulated by the Austrian R&D funding scheme in the field of intelligent transport systems in 2006. We focus on three different forms of behavioural additionality project additionality, scale additionality and...

  11. On conjugate families and Jeffreys priors for von Mises-Fisher distributions

    Hornik, Kurt; Grün, Bettina
    This paper discusses characteristics of standard conjugate priors and their induced posteriors in Bayesian inference for von Mises-Fisher distributions, using either the canonical natural exponential family or the more commonly employed polar coordinate parameterizations. We analyze when standard conjugate priors as well as posteriors are proper, and investigate the Jeffreys prior for the von Mises-Fisher family. Finally, we characterize the proper distributions in the standard conjugate family of the (matrixvalued) von Mises-Fisher distributions on Stiefel manifolds.

  12. Verschiedene Menschen, verschiedene Krisen: Die aktuelle Krise aus intersektionaler Sicht

    Schneebaum, Alyssa
    Unterschiedliche Bevölkerungsgruppen sind von der aktuellen Wirtschaftskrise unterschiedlich stark betroffen. In den USA wird von einer »Mancession« gesprochen, was zum Ausdruck bringen soll, dass Männer besonders in Bezug auf Beschäftigung und Einkommen stärker als Frauen betroffen sind. Dieser Artikel bespricht derartige Unterschiede in Bezug auf verschiedene Bevölkerungsgruppen. Insbesondere wird eine intersektionale Perspektive eingenommen, also verschiedene sozioökonomische Charakteristika gemeinsam betrachtet, sowie Erkenntnisse der Soziologie und Ökonomie kombiniert.
