The extent of economic losses due to a natural hazard and disaster depends largely on the spatial distribution of asset values in relation to the hazard intensity distribution within the affected area. Given that statistical data on asset value are collected by administrative units in China, generating spatially explicit asset exposure maps remains a key challenge for rapid postdisaster economic loss assessment. The goal of this study is to introduce a top‐down (or downscaling) approach to disaggregate administrative‐unit level asset value to grid‐cell level. To do so, finding the highly correlated “surrogate” indicators is the key. A combination of three data sets—nighttime light grid, LandScan population grid, and road density grid, is used as ancillary asset density distribution information for spatializing the asset value. As a result, a high spatial resolution asset value map of China for 2015 is generated. The spatial data set contains aggregated economic value at risk at 30 arc‐second spatial resolution. Accuracy of the spatial disaggregation reflects redistribution errors introduced by the disaggregation process as well as errors from the original ancillary data sets. The overall accuracy of the results proves to be promising. The example of using the developed disaggregated asset value map in exposure assessment of watersheds demonstrates that the data set offers immense analytical flexibility for overlay analysis according to the hazard extent. This product will help current efforts to analyze spatial characteristics of exposure and to uncover the contributions of both physical and social drivers of natural hazard and disaster across space and time.  相似文献

我国《民法总则》明确了网络虚拟财产受法律保护,这是财产保护的一大进步,但是理论和实践中,网络虚拟财产却存在着性质和权属难以确定、分割和继承规则不明确等一系列问题。对涉及淘宝网店财产分割的审判案例进行数据分析,发现审判实践中存在着财产分割没有法律依据、价值难确定、归属不公平的困境。针对这些困境,在对夫妻网络虚拟财产进行分割时要注意保护虚拟财产的特殊性,提前明确共同财产范围,组织多机构联合评估价值,保护人身利益。  相似文献

Few measures parallel the robust depth offered in the existing multidimensional and ecologically informed theories of resilience. This study sought to evaluate the test–retest reliability, construct, and predictive validity of the individual, family, and community resilience resource profile (IFCR-R). The IFCR-R measures a family’s access to resilience resources and protective factors across multiple ecological levels. Confirmatory factor analysis was used with a sample of n?=?810 low-income families. And 159 families completed multiple time point measures for test–retest reliability and predictive validity evaluation. Results of this study support the proposed multidimensional ecological structure of the IFCR-R and found that the IFCR-R offers an acceptable test–retest reliability and predictive validity for outcomes of mental and physical health.  相似文献

ABSTRACT

Research has explored how care managers in elder care – who often function as ‘street-level bureaucrats’ – regard professional discretion. The way in which length of work experience affects care managers’ use of professional discretion remains, however, unexplored. This article present findings from 12 focus groups with 60 care managers. By bringing attention to how care managers experience the needs assessment process, this article sheds light on how these ‘street-level bureaucrats’ struggle when they try to balance their clients’ needs against institutional frameworks and local guidelines. Length of work experience seems to play a role in how care managers claim to use professional discretion. Experienced care managers describe how they deviate from the guidelines at times in order to create an increased scope of action in their decision-making process. Those with less time in the profession describe greater difficulties in this respect. Findings suggest that research should explore if length of work experience plays a role in the actual way in which care managers assess needs and make decisions. As such, they contribute to our understanding of how needs assessment processes are navigated by professionals while also pointing towards the nature of professional discretion in gerontological social work.  相似文献

Career counselors must continually enhance their knowledge and skills to assist clients contemplating careers in science, technology, engineering, and mathematics (STEM). Therefore, the authors review STEM disciplines and theory‐driven strategies for assisting diverse individuals to explore, enter, and persist in STEM careers. Appropriate use of career assessments can contribute greatly to this effort. To identify available measures for STEM‐focused domains and constructs, the authors conducted a journal content analysis of stand‐alone STEM‐related career assessments from 1983 to 2016, identifying 39 articles with 153 measures. Notable results included the emergence of social cognitive theory and social cognitive career theory as prevailing frameworks for instrument development, a wide variety of disciplines and journals represented, an underrepresentation of minority samples, and untapped potential for cross‐discipline and researcher–practitioner collaboration. Useful strategies and resources for counselors and recommendations for enhancing career assessments and interventions are addressed.  相似文献
