The aim of this paper is to analyse the impact of the recent Spanish housing boom and the subsequent burst on local public finances. Particularly, we investigate the effect of the rise and later fall in revenue from urban development on local government debt. Using a sample of the Spanish largest municipalities in the period 2003–2011, we find that debt was substituted by revenue from urban development during boom years and this substitution effect vanished after the burst of the boom. Our results also reveal that local public finances have worsened after the burst of the housing bubble since now they have larger current spending and smaller savings.  相似文献

As literature is poor in functional synthetic cranial models, in this study, synthetic handmade models of cranial vaults were produced in two different materials (a urethane resin and a self‐hardening foam), from multiple bone specimens (eight original cranial vaults: four human and four swine), in order to test their resemblance to bone structure in behavior, during fracture formation. All the vaults were mechanically tested with a 2‐kg impact weight and filmed with a high‐speed camera. Fracture patterns were homogeneous in all swine vaults and heterogeneous in human vaults, with resin fractures more similar to bone fractures. Mean fracture latency time extrapolated by videos were of 0.75 msec (bone), 1.5 msec (resin), 5.12 msec (foam) for human vaults and of 0.625 msec (bone), 1.87 msec (resin), 3.75 msec (foam) for swine vaults. These data showed that resin models are more similar to bone than foam reproductions, but that synthetic material may behave quite differently from bone as concerns fracture latency times.  相似文献

Abstract

The current study examined the consistency of investigative interviewers' performance (n=31) across three distinct interview paradigms: (a) a mock interview where an adult actor played the role of a child recalling abuse, (b) a mock interview where a school child recalled an innocuous event that was staged at the child's school, and (c) a field interview where the interviewer elicited a statement of abuse from a child. Performance was measured by calculating the proportion of open-ended and leading questions, and by eliciting expert ratings of the presence of a range of problem behaviours commonly exhibited by interviewers. Overall, the performance of individual interviewers was relatively stable across the tasks. Heterogeneity in stability, however, differed according to the type of question and the nature of the event being examined. In particular, the mock interview paradigm where the adult acted the role of an alleged child abuse victim produced a measure of performance that was more similar to the field interview than the interview where a school child recalled an innocuous event. The implications of the findings for trainers, and directions for future research, are discussed.  相似文献

Federal programs have consistently encouraged ever-lower-income households to buy homes, despite concerns about the long-term sustainability and desirability of homeownership from the perspective of wealth-building, especially since the recent housing market collapse and the epidemic of mortgage foreclosures. We ask in this paper: can very low-income households build wealth through sustainable homeownership, with the aid of an innovative public program? We answer this question by examining 122 very low-income households who purchased their homes between 1996 and 2007 after completing an extensive asset-building and homeownership education/counseling program offered by the Housing Authority of the City and County of Denver (DHA), called HOP. We analyze our own longitudinal surveys and focus groups, as well as data compiled from administrative agency sources, real estate records, and longitudinal census data from the Neighborhood Change Database and the Piton Foundation's Neighborhood Facts Database. We find that homeownership attained through HOP typically did provide very low-income households with opportunities to build home equity (both absolutely and relative to generic homeowner cohorts in Denver) and net wealth, although this was contingent on time of purchase and ethnicity. Our multivariate analyses revealed that changes in annualized home equity appreciation were associated with the ethnic composition of the neighborhood and age of property. Annualized wealth accumulation was associated with annualized home equity appreciation, being married throughout the tenure of homeownership, and year of home purchase. HOP homebuyers received exceptionally favorable initial mortgage terms and conditions, often enhanced with down-payment assistance from their own DHA escrow account or from local housing and neighborhood development organizations, resulting in a dramatically low rate of default and foreclosure to date. Moreover, HOP homebuyers were not immune to financial stresses, and the continuing lack of wealth for many makes them vulnerable to future interruptions in primary wage earner's employment or health. We discuss the implications for low-income homeownership policy and argue that the goal of expanding homeownership opportunities should not be abandoned.  相似文献

We report here a review of the seventh mitochondrial DNA (mtDNA) exercise undertaken by the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) corresponding to the period 2003-2004. Five reference bloodstains from five donors (M1-M5), a mixed stain of saliva and semen (M6), and a hair sample (M7) were submitted to each participating laboratory for nuclear DNA (nDNA; autosomal STR and Y-STR) and mtDNA analysis. Laboratories were asked to investigate the contributors of samples M6 and M7 among the reference donors (M1-M5). A total of 34 laboratories reported total or partial mtDNA sequence data from both, the reference bloodstains (M1-M5) and the hair sample (M7) concluding a match between mtDNA profiles of M5 and M7. Autosomal STR and Y-STR profiling was the preferred strategy to investigate the contributors of the semen/saliva mixture (M6). Nuclear DNA profiles were consistent with a mixture of saliva from the donor (female) of M4 and semen from donor M5, being the semen (XY) profile the dominant component of the mixture. Strikingly, and in contradiction to the nuclear DNA analysis, mtDNA sequencing results yield a more simple result: only the saliva contribution (M4) was detected, either after preferential lysis or after complete DNA digestion. Some labs provided with several explanations for this finding and carried out additional experiments to explain this apparent contradictory result. The results pointed to the existence of different relative amounts of nuclear and mtDNAs in saliva and semen. We conclude that this circumstance could strongly influence the interpretation of the mtDNA evidence in unbalanced mixtures and in consequence lead to false exclusions. During the GEP-ISFG annual conference a validation study was planned to progress in the interpretation of mtDNA from different mixtures.  相似文献

Citizens are increasingly concerned with environmental issues and some of them take contentious political actions or adapt their lifestyles to reduce their environmental footprint. Research finds that there is an eco-gender gap in everyday environmental behaviours, with women more active than men. However, studies of the eco-gender gap have infrequently looked at other forms of pro-environmental political behaviours and focused mostly on young people. We contribute to the literature by examining to what extent older women and men differ in a range of pro-environmental political behaviours, using a unique dataset based on a survey of individuals 64 years and older. We find strong evidence of a gender gap in everyday behaviours and political consumerism, but not in relation to contentious forms of political participation. This gender gap in relation to everyday behaviours and political consumerism diminishes with age.  相似文献

Many studies suggest that mixed‐member electoral systems produce different attitudes and behaviors among representatives. This article assesses how this type of electoral system shapes Bolivian legislators' perceptions of their roles as representatives, their district activities, and their relationships with their political parties. It examines these dimensions using elite survey data and interviews with legislators and their personal assistants. The results show that the electoral system does not produce a uniform impact. It shapes how legislators perceive their role as representatives and the nature of the relationship they build with their political parties, but it does not produce differences in the kinds of activities that both types of legislators carry out in their districts.  相似文献

Victims of crime are often confused and frustrated by the criminal justice process. Those who have lost loved ones to homicide – often called ‘homicide survivors,’ ‘secondary victims,’ or ‘co-victims’ – suffer not only loss and a justice system that seems to have little place for them, but are often also left unaware of the circumstances of their loved one’s death. The current study sought to further our understanding of the experience of homicide survivors in the Canadian justice system. Toward this end, in-depth, semi-structured interviews were conducted with five individuals who lost loved ones to homicide. Results showed that receiving information and being treated kindly were far more important than having an influence over the proceedings; additionally, there was a great deal of distrust of the justice system as a whole, regardless of the kindness shown by individual actors in the system. Policy implications and directions for future research are discussed.  相似文献
