We estimate the country-level risk of extreme wildfires defined by burned area (BA) for Mediterranean Europe and carry out a cross-country comparison. To this end, we avail of the European Forest Fire Information System (EFFIS) geospatial data from 2006 to 2019 to perform an extreme value analysis. More specifically, we apply a point process characterization of wildfire extremes using maximum likelihood estimation. By modeling covariates, we also evaluate potential trends and correlations with commonly known factors that drive or affect wildfire occurrence, such as the Fire Weather Index as a proxy for meteorological conditions, population density, land cover type, and seasonality. We find that the highest risk of extreme wildfires is in Portugal (PT), followed by Greece (GR), Spain (ES), and Italy (IT) with a 10-year BA return level of 50'338 ha, 33'242 ha, 25'165 ha, and 8'966 ha, respectively. Coupling our results with existing estimates of the monetary impact of large wildfires suggests expected losses of 162–439 million € (PT), 81–219 million € (ES), 41–290 million € (GR), and 18–78 million € (IT) for such 10-year return period events.
SUMMARY
We model the risk of extreme wildfires for Italy, Greece, Portugal, and Spain in form of burned area return levels, compare them, and estimate expected losses. 相似文献72.

This study examined the prediction of different forms of adult aggression in 2 countries from child and adolescent aggression. It was based on 2 longitudinal projects: the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS; N=196 boys and 173 girls) conducted in Finland and the Columbia County Longitudinal Study (CCLS; N=436 boys and 420 girls) conducted in the United States. The same peer‐nominated items for aggression were used in both studies at age 8; comparable measures of aggression were also available in adolescence (age 14 in the JYLS/19 in the CCLS) and adulthood (ages 36/30 and 42/48). Results showed that in both countries and in both genders, aggression in school age was linked significantly to physical aggression and lack of self‐control of anger in adulthood but not to verbal aggression. This differential predictability of aggression over 40 years suggests that individual differences in physical aggression are more determined by lasting individual differences (including emotional reactivity) than are individual differences in verbal aggression. 相似文献

European schemes of social assistance: an empirical analysis of set-ups and distributive impacts 总被引:3,自引:0,他引:3
This article analyses the distributive impacts of various statutory and institutional settings of European schemes of social assistance. For this purpose, two sets of classifications of European schemes of social assistance are introduced, which classify the systems according to their level and statutory settings and according to their degree of centralisation, respectively. Subsequently, the distributive impacts of seven selected EU systems are calculated on the basis of Luxembourg Income Study (LIS) data and their relationship to class assignment is investigated. We find that a high share of social assistance recipients in the population concurs with better distributive effectiveness, while a higher social assistance budget or higher benefit levels do not necessarily yield a better performance. Various forms of targeting seem to enhance distributive efficiency. Concerning centralisation, the results do not show that a certain degree of centralisation yields better results with regard to distributive effectiveness or efficiency. 相似文献

The electronic purse (chip-card) is promoted as an option offering consumers an easy means of payment. It also offers advantages to traders and banks by reducing transaction costs. However, successful launching of the electronic purse depends mainly on consumers' acceptance, which in the past was very low in Austria. We study consumers' acceptance of the electronic purse, cash and established non-cash payment systems by analysing social representations of payment facilities. Semantic contents of associations raised in response to the stimulus words “means of payment in general”, “cash”, “cheque”, “ATM-card”, “credit-card” and “electronic purse” have been analysed. Overall, 264 people were studied applying two techniques: the “associative network” and the “conceptual network”. It is shown that means of payment are categorised on two dimensions: cash and non-cash. Non-cash payment facilities are characterised by high abstraction levels, and loss of subjective control over expenditures. The electronic purse is perceived as highly dissimilar to other means of payments. 相似文献

This article examines the population trends in the cities of the Russian Far East between the two census years 1989 and 2002. Three geographical models – Rank-Size Rule, Temperature per Capita and a simple gravity model – are used to describe the direction of these population trends. An economic efficiency function is constructed from the three models to simulate an ideal population distribution for the Russian Far East. The heart of the simulation is a conjugate gradient optimisation of the economic efficiency function. The results serve as an important backdrop to discussions of current population trends and serve as an important backdrop to discussions of current population trends and as basis for recommendations concerning future changes in the spatial distribution of population in the region.Mueller, K., et Bradshaw M.

This study examined the temporal stability of recalled parental rearing behavior (RPRB) in a community sample of adolescents and young adults (aged 15–19 at first assessment, N = 945) over a period of nearly two years. RPRB (overprotection/control, rejection/punishment, and emotional warmth, separately for mother and father) was assessed at two assessment waves (time interval: M = 21.18 months, SD = 0.09 months) using the Questionnaire of Recalled Parental Rearing Behavior. Intraclass correlations (ICCs) between both assessments were examined. ICCs were similar for maternal and paternal RPRB and slightly higher for emotional warmth (mother: .70; father: .70) than for rejection/punishment (mother: .69; father: .68) and overprotection/control (mother: .66; father: .62). These findings suggest an at least moderate temporal stability of RPRB in adolescents of the community. 相似文献

This article examines a child migration scheme which aimed at permanently resettling British children to Southern Rhodesia during 1946–1962. First, the philanthropic scheme was framed in terms of child welfare; it sought to benefit selected children by removing them from their homes and resettling them at Rhodesia Fairbridge Memorial College, a boarding school and children’s home. Second, the scheme aimed at advancing Empire building more broadly by increasing the number of white citizens in Africa. The article considers how the Fairbridge scheme distinctively combined physical and social mobility. The children were expected, through first-class education, to rise to privileged positions, thus maintaining the colonial, racially segregated social hierarchy. By focusing on implicit forms of education at the boarding school, analysed as a ‘Goffmanian’ total institution, the article considers the ambiguous intents and outcomes of a very particular project of colonial social engineering. 相似文献

The “transnational” (Bartlett & Ghoshal, 1988, 1989) has become a popular organizational construct, and is increasingly relevant to contemporary global firms. However, there is very little empirical research on the organizational aspects of this form, and there is a lack of knowledge regarding the transnational aspects in professional service firm theorizing. Building on some fundamental organizational and international management literature, as well as an understanding of contemporary global professional firms, we expect that the transnational will exhibit specific organizational structural features with both high levels globalization and local responsiveness. We then proceed to describe an exploratory study of ten global engineering firms—this context is important since engineering firms are far less tied to national (local) jurisdictions than are other professional firms. Our findings reveal that the leadership/management areas were largely globally integrated, the hiring/HR functions were singularly locally oriented, while the other organizational areas we studied – namely structure/process and project teams – exhibited both global and local features. These findings extend professional service firm theorizing, exposing the balance between axes of specialisation, norms of reciprocity and customer management system; to include organizational features that allow a balance between the globally integrated and locally responsive. 相似文献

The theory of representative bureaucracy suggests that organizationsperform better if their workforces reflect the characteristicsof their constituent populations. The management literatureimplies that the impact of representative bureaucracy is contingenton organizational strategy. Our empirical evidence on Englishlocal government is inconsistent with the basic theory of representativebureaucracy but supports a moderating effect of organizationalstrategy. Representative bureaucracy is negatively associatedwith citizens' perceptions of local authority performance. However,organizations pursuing a prospector strategy are able to mitigatethis negative relationship. 相似文献
