Abstract

This article documents the growing importance of preventive servicing—business practices that emphasize early intervention in delinquency and default management practices that also help financially troubled borrowers avoid foreclosure. We suggest that the loan servicing side of the affordable housing delivery system may be underappreciated and undercapitalized.

We use a database of more than 28,000 affordable housing loans to test several preventive servicing‐related propositions and find that after we control for loan and borrower characteristics, the likelihood that a delinquent mortgagor within this universe will ultimately default varies significantly across servicers. This suggests that loan servicing is an important factor in determining whether low‐ and moderate‐income borrowers who fall behind in their mortgage payments will end up losing their homes through foreclosure. It also suggests a need for policy makers to incorporate preventive servicing into affordable homeownership programs.  相似文献

This paper develops an ordinal index to measure the openness of FDI policy regimes for individual countries. There has been a generalised increase in the index between 1990 and 2002. The most important determinants of variations in FDI flows across countries and over time are country size, the level of educational achievement, and growth. The openness index is positively associated with FDI flows, but its explanatory power is low. Liberalising approval procedures and lifting requirements that foreign companies enter into joint ventures with domestic firms encourage FDI. We conclude that the openness of the FDI regime operates as a factor enabling FDI, but that location advantages are paramount in determining the international allocation of FDI. We also turn the question around and ask what countries are more likely to impose restrictions on FDI. We find that lower levels of education and larger domestic markets are associated with greater restrictions on FDI. In addition, there is some evidence that better institutions are associated with lower FDI restrictions.  相似文献

The aim of this study is to identify protective and risk factors related to the development of posttraumatic stress disorder (PTSD) on a sample of survivors from a single plane crash. Eighteen survivors were examined 6 months following the event. The subjects all underwent psychiatric interviews, Clinician‐Administered PTSD Scale structured interviews, personality and cognitive tests. Only 38.9% of them presented with all of the symptoms of PTSD; 22.2% showed no symptoms for PTSD; remaining survivors exhibited emotional/affective symptoms related to the event. In addition to the severity of the traumatic event itself, other risk factors identified were the loss of a relative, the manifestation of depressive symptoms, and the severity of physical injuries sustained. Low levels of hostility and high levels of self‐efficacy represented protective factors against developing PTSD.  相似文献

We investigate the role of search strategy in shaping firms’ innovation performance. Firms use a wide range of external actors and sources to help them achieve and sustain innovation. In particular, the extension (breadth) and the relevance (depth) of such sources determine firms’ ability to extract and exploit knowledge and new ideas and, thus, to be innovative. Using a sample of firms in a regional context active in R&D, we built separate measures of breadth and depth for local (on a regional scale) and global (outside the regional context) search. This allows us to investigate whether localized or global knowledge spillovers are in place. We find that a wider set of partners increases coordination costs, while greater depth in search strategies contributes to innovation. We find that a more diversified search strategy at the local level (greater breadth of search) results in significant payoffs in terms of innovation, while diversifying the partnership with Italian partners has a smaller, although still positive, effect. In contrast, the benefits of depth of innovation are greatest at the global level. In addition, a broader set of information sources for R&D projects has a significant positive effect on innovation. Finally, firms that resort to R&D subsidies are less innovative.  相似文献

Abstract: In Italy, the “silent‐consent” principle of donor’s willingness regulates organ donation for postmortem transplantation, but civil incompetence excludes it. We investigated decisional capacity for organ donation for transplantation of 30 controls and 30 nonincompetent patients with schizophrenia as related to clinical symptoms, cognition, and functioning. Assessments were carried out through the Competence for Donation Assessment Scale (CDAS), Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Positive Symptoms (SAPS), Scale for the Assessment of Negative Symptoms, Life Skills Profile (LSP), Raven’s Colored Progressive Matrices (RCPM), Wisconsin Card Sorting Test, Rey RI, Rey RD, and Visual Search. Patients and controls differed on the CDAS Understanding and Choice Expression areas. Patients showed significant inverse bivariate correlations between CDAS Understanding and scores on total BPRS, LSP self‐care scale, and RCPM cognitive test. Our results show that decisional capacity for participating in research does not predict decisional capacity for postmortem organ donation in patients with schizophrenic or schizoaffective psychosis; hence, before judging consent for donation, patients must be provided with enhanced information to better understand this delicate issue.  相似文献

Allele frequencies for 15 short tandem repeats (STR) loci were determined with a sample of 3000 unrelated individuals from the population of Santa Catarina, Southern Brazil. The loci are most commonly used in forensic and paternity testing, being analyzed by the Powerplex 16 (Promega) commercial kit. The data shows that most polymorphic loci were Penta E and FGA. The distributions of the genotypes in the evaluated loci are in Hardy–Weinberg equilibrium. Comparative analyses between our population data and other Brazilian populations are presented. The calculated forensic parameters showed that the loci are useful for the solution of forensic problems in Brazilian Southern region.  相似文献

Abstract:  The aim of this study was to investigate the possibility of distinguishing deaths by asphyxia from those due to natural causes by comparing morphometric measurements in lungs. The study population comprised 27 subjects: 14 cases of death by asphyxia (hanging or drowning) and 13 cases of sudden natural death. Eighty parenchyma sections were used for each subject. Data were collected by computerized image analysis. Measurements aimed at quantifying, as percentages, pulmonary parenchyma (mean values of positive-fraction areas [PFA] and their standard deviations). Subjects who died of natural causes and of drowning showed a relative internal homogeneity compared to those who hanged. Results show significant discrimination between drowned subjects and those dying of natural causes (mean of PFA p  = 0.01) and between hanged and drowned subjects (SD of PFA p  = 0.04). Attention must be paid to the possible role played by senile emphysema. The method is proposed as a complementary tool in forensic cases.  相似文献

This paper presents data on the prevalence of co-occurring substance use and psychiatric disorders among newly imprisoned males in Italy. Interviewers conducted semi-structured clinical interviews with n = 302 male detainees seven days after their admission to the prison of Perugia from August 2005 through July 2006. Over half of male detainees (54.3%) had either a substance use disorder or another psychiatric disorder. One of every five detainees (20.9%) had comorbid substance use and psychiatric disorders. Compared to detainees with psychiatric disorder only, substance use disorder only, or no disorder, detainees with comorbid substance use and psychiatric disorders were significantly more likely to have severe impairment in the areas of employment, substance abuse, family and social functioning, and psychiatric symptoms. Findings underscore the need for careful diagnostic screening at intake, access to treatment during detention, and an effective transition to services at the time of release.  相似文献
