This article explores the relationship between employment mobility, family fixity, and gentrification in the lives of 36 residents in and extended commuters to Montreal's southwest borough. Once described as the birthplace of industry in Canada, the neighbourhoods of Saint-Henri, Little Burgundy and Point Saint-Charles have undergone sweeping changes in recent decades. Inner-city areas are not necessarily where one expects to find mobile workers, but this is changing due to shifting gender roles, the rise of dual-income households and gentrification. Michael Savage's concept of ‘elective belonging’ proved particularly useful in understanding this connection. With its proximity to childcare, schools, stores and workplaces, the central city permits a more equitable division of labour within the household. Our place-based approach to mobile work enables us to capture a wide spectrum of experience, ranging from people with extended daily commutes to those whose work takes them away from home for days, weeks or months at a time. Our interviews reveal a connection between employment mobility and family gentrification, as upwardly mobile families find ways to localize other aspects of their lives. The simultaneity of mobility and immobility are often essential, especially in dual-income households. One parent's mobility often leads to the relative immobility of other family members.  相似文献

Based on a novel extension of existing multivariate Markov-switching models, we provide the reader with a useful tool for analyzing current business conditions and making predictions about the future state of the Euro-area economy in real time. Apart from the Industrial Production Index, we find that the European Commission Industrial Confidence Indicator, which is issued with no delay, is very useful for constructing the real-time predictions.  相似文献

企业为了搞好经营,都十分重视提高员工的工作积极性,而提高员工的工作积极性往往采取增加薪酬、改善福利的方式,当然,这种方式的运用无可厚非,也比较见效,但随着企业各项制度的不断完善和员工构成的高学历化,单纯的经济刺激已不足以应对员工的多元化需求;因此重新审视我党的思想政治工作,将它与企业文化建设有机结合,在提高员工经济收入的同时,努力提高员工的“精神收入”,成为企业提升管理品质、吸引人才、锻造内力的有效途径。  相似文献

The approach, descent, and climb phases of flights in terminal maneuvering areas (TMAs) are some of the critical parts of a flight in which more than half of accidents happen. For an ANSP (Air Navigation Service Provider), to fulfill the responsibility with a high-quality service degree while maintaining safety, these difficult areas should be designed carefully and equipped with the most efficient procedures. Point merge system (PMS), which is defined as a systemized method for sequencing arrival flows, is launched in Istanbul's new TMA (LTFM TMA) being designed by DHMI (Devlet Hava Meydanları Isletmesi) to improve safety and efficiency. In this paper, the airspace complexity is based on adjusted density and structural index, and safety indicators. To investigate the effects of the radical changes made in re-organized LTFM TMA on the safety issue in comparison with the previous terminal maneuvering area, LTBA TMA, six months' data consisting of 75215 arrival and departure flights are used. Results reflect that the LTFM TMA, one of the world's busiest terminal airspaces, has statistically significantly lower scores in terms of conflict numbers per aircraft, complexity metrics, adjusted density, the hour of interactions, and flight hours than LTBA TMA. Lastly, there exists no longer a significant relationship between conflict types and complexity after launching the new design and structure.  相似文献

This paper develops Area-wide Leading Inflation CyclE (ALICE) indicators with the aim to provide early signals for turning points in the euro area headline and core inflation cycles. The headline (core) ALICE leads the reference cycle by three (four) months and the lead times extend to five (nine) months based on longer-leading series. Both ALICE indicators signalled turning points in the inflation cycles ex post and also performed well in a simulated real-time exercise. Moreover, in particular the headline ALICE also appeared to be useful for quantitative forecasting of the direction and level of inflation.  相似文献

We analyze the relationship between forecaster disagreement and macroeconomic uncertainty in the Euro area using data from the European Central Bank’s Survey of Professional Forecasters for the period 1999Q1–2018Q4 and find that disagreement is generally a poor proxy for uncertainty. However, the strength of this link varies with the dispersion statistic employed, the choice of either the point forecasts or the histogram means for calculating disagreement, the outcome variable considered and the forecast horizon. In contrast, distributional assumptions do not appear to be very influential. The relationship is weaker in subsamples before and after the outbreak of the Great Recession. Accounting for the forecasters’ entry to and exit from the survey has little impact on the results. We also show that survey-based uncertainty is associated with overall policy uncertainty, whereas forecaster disagreement is related more closely to the expected fluctuations on financial markets.  相似文献

Forecasting and turning point predictions in a Bayesian panel VAR model   总被引:2,自引:0,他引:2  
We provide methods for forecasting variables and predicting turning points in panel Bayesian VARs. We specify a flexible model, which accounts for both interdependencies in the cross section and time variations in the parameters. Posterior distributions for the parameters are obtained for hierarchical and for Minnesota-type priors. Formulas for multistep, multiunit point and average forecasts are provided. An application to the problem of forecasting the growth rate of output and of predicting turning points in the G-7 illustrates the approach. A comparison with alternative forecasting methods is also provided.  相似文献
