A Survey of Active Learning for Quantifying Vegetation Traits from Terrestrial Earth Observation Data
2021
The current exponential increase of spatiotemporally explicit data streams from satellite-based Earth observation missions offers promising opportunities for global vegetation monitoring. Intelligent sampling through active learning (AL) heuristics provides a pathway for fast inference of essential vegetation variables by means of hybrid retrieval approaches, i.e., machine learning regression algorithms trained by radiative transfer model (RTM) simulations. In this study we summarize AL theory and perform a brief systematic literature survey about AL heuristics used in the context of Earth observation regression problems over terrestrial targets. Across all relevant studies it appeared that…
A multidisciplinary approach to the evaluation of the mechanism that triggered the Cerda landslide (Sicily, Italy).
2005
Abstract The present paper describes a multidisciplinary approach to the evaluation of a seismically triggered landslide that occurred in the Cerda area (Italy) on September 6, 2002, about 1 h after an earthquake took place in the south Tyrrhenian Sea. The study was focused on an analysis of the role of the seismic input in triggering the landslide, in view of the evidence that no other mass movement was recorded in the adjacent areas despite geological and geomorphological spatial homogeneity. The studied area is located on a slope of the western flank of the Fiume Imera Settentrionale (Northern Sicily), which is made up of clayey–arenitic rocks. The slope inclines gently but is not unifor…
Overcoming the crisis : the changing profile and trajectories of Latvian migrants
2016
The work was funded by the National Research Programme [grant number 5.2.4] and the Latvian Council of Sciences [grant number 514/2012]. Taking mobility between Latvia and Western Europe as an empirical lens, this analysis explores the complex relationship between spatial disparities in earning potential and migration. The very dramatic shifts in the economic and political context against which migration from Latvia has occurred over the period 2004-2012 make it an especially apposite focus of research investigating the link between mobility and labour market circumstances. As an analytical starting point, conventional economic theory broadly explains the movement of workers from lower to h…
How do employed women perceive the reconciliation of work and family life?
2012
PurposeThe purpose of this paper is to analyze how employed women perceive the reconciliation of work and family life in Denmark, Germany, France, Finland, Great Britain, Sweden and Switzerland. The paper seeks to explore why women in certain countries are more successful in combining family responsibilities with gainful employment.Design/methodology/approachDrawing on data from the International Social Survey Programme (ISSP) 2005, the questions are addressed by applying country specific linear regression analysis at the individual level, correlations at the country level as well as policy analysis.FindingsThe analysis shows that the most important factors influencing employed women's perc…
Surveying Supported Employment in Finland: A Follow-up
2007
The longitudinal status of supported employment in Finland was examined via a 2003 nationwide survey sent to job coaches involved in supporting workers with intellectual and other disabilities. Sustained supported employment, defined as "paid work in integrated settings with ongoing supports that contained at least two on-site visits per month at the worksite" was identified at 22 organizations that supported 52 workers. The results of the current survey were compared with those gained from similar surveys conducted in 1998, 1999, and 2001. Comparison of data over a 6-year period showed a decline in the provision of intensive employment supports and appeared to reflect both a change in Euro…
Getting support in polarized societies: Income, social networks, and socioeconomic context
2013
AbstractThis paper explores how unequal resources and social and economic polarization affects the size of social networks and their use to access resources. We argue that individual resource position generates divergent expectations with regard to the impact of polarization on the size of networks on one hand, and their usefulness for accessing resources on the other. Social and economic polarization encourages reliance on informal networks, but those at the bottom of the social structure are forced to rely on more extensive networks than the wealthy to compensate for their isolated and underprivileged position. At the same time, social and economic polarization limits the resources the po…
Profit, morality and discrimination
2021
Using an original vignette survey, we study the normative acceptability of the trade-off between immoral profit (discrimination) and costly morality (non-discrimination). We test the causal influen...
Households' Balance Sheets and the Effect of Fiscal Policy
2022
Using households' balance-sheet composition in the Panel Survey of Income Dynamics, we identify six household types. Since 1999, there has been a decline in the share of patient households and an increase in the share of impatient households with negative wealth. Using a six-agent New Keynesian model with search and matching frictions, we explore how changes in households' shares affect the transmission of government spending shocks. We show that the relative share of households in the left tail of the wealth distribution plays a key role in the aggregate marginal propensity to consume, the magnitude of fiscal multipliers, and the distributional consequences of government spending shocks. W…
Depression of the deprived or eroding enthusiasm of the elites: What has shifted the support for international trade?
2020
Abstract We use the 2003 and 2013 waves of the International Survey Program (ISSP) in order to explore the change in people’s attitudes that may be behind the recent backlash against globalization. We show that the average support for international trade has decreased in many – albeit not all – countries, and we demonstrate that these changes are related to the depth and length of the global financial crisis of 2008/09 as well as the evolution of income inequality. Moreover, our results document a declining support of those individuals who are likely to benefit from international trade: the young, high-skilled and well-off. We show that this “eroding enthusiasm of the elites” is empirically…
Is Communism to Blame for Political Disenchantment in Post-Communist Countries? Cohort Analysis of Adults' Political Attitudes
2014
In this article, we apply a new, original technique of cohort analysis to test empirically whether political disenchantment in the post-communist countries of Central and Eastern Europe can be linked to the previous political culture. On the basis of International Social Survey Programme 1996 and 2006 data we find a surprisingly similar and unique cohort effect in all analysed post-communist countries, reflecting persistent generational differences in perceived political competence (interest and understanding of political processes). However, the communist legacy does not seem to be important for explaining low self-efficacy or distrust in political authorities and their responsiveness to c…
