The Terra Populus project (TerraPop) addresses a variety of data management, curation, and preservation challenges with respect to spatiotemporal population and environmental data. In this article, we describe our approaches to these challenges, with a particular focus on geospatial data workflows and associated provenance metadata. The goal of TerraPop is to enable research, learning, and policy analysis by providing integrated spatiotemporal data describing people and their environment. To do so, TerraPop is assembling a globe-spanning and temporally extensive collection of high-quality population and environmental data, ensuring good documentation, and developing a Web-based data access system that enables users to assemble customized integrated data sets drawing on a variety of data sources and formats. We describe TerraPop's collection strategies, detail the geospatial workflows involved in preparing data for ingest into the project database and those used to transform data across formats for dissemination, and discuss the system used to capture and manage provenance metadata throughout the project. A key aspect of the project is the development of global current and historical administrative unit boundaries that can be linked to census data. These boundaries serve as the linchpin of TerraPop's data integration strategy, and constitute an important data set in their own right.  相似文献

OBJECTIVES: To examine the relationship of childhood physical and sexual abuse with reported parenting satisfaction and parenting role impairment later in life among American Indians (AIs). METHODS: AIs from Southwest and Northern Plains tribes who participated in a large-scale community-based study (n=3,084) were asked about traumatic events and family history; those with children were asked questions about their parenting experiences. Regression models estimated the relationships between childhood abuse and parenting satisfaction or parenting role impairment, and tested for mediation by depression or substance use disorders. RESULTS: Lifetime substance use disorder fully mediated the relationship between childhood physical abuse and both parenting satisfaction and parenting role impairment in the Northern Plains tribe. There was only partial mediation between childhood sexual abuse and parenting role impairment in the Southwest. In both tribes, lifetime depression did not meet the criteria for mediation of the relationship between childhood abuse and the two parenting outcomes. Instrumental and perceived social support significantly enhanced parenting satisfaction; negative social support reduced satisfaction and increased the likelihood of parenting role impairment. Exposure to parental violence while growing up had deleterious effects on parenting outcomes. Mothers and fathers did not differ significantly in the relation of childhood abuse experience and later parenting outcomes. CONCLUSIONS: Strong effects of social support and mediation of substance abuse disorders in the Northern Plains offer direct ways in which childhood victims of abuse could be helped to avoid negative attributes of parenting that could put their own children at risk. PRACTICE IMPLICATIONS: Mothers were not significantly different from fathers in the relation of abusive childhood experiences and later parenting outcomes, indicating both are candidates for interventions. Strong effects of social support offer avenues for interventions to parents. The prevalence of substance use disorders and their role as a mediator of two parenting outcomes in the Northern Plains should focus special attention on substance use treatment, especially among those who experienced childhood victimization. These factors offer direct ways in which childhood victims of abuse can be helped to avoid negative attributes of parenting that could put their own children at risk of violence.  相似文献

The Americans with Disabilities Act created regulations for the accessibility of buildings and services for individuals with disabilities, but libraries still have a deficit in information highlighting disability and accessibility. Using LibGuides 2.0 software, the authors created 22 accessible guides on disabilities, disability theory, and assistive technology. The initial response from users was positive and included feedback as the guides continue to be improved and built upon. This article is a case study on the creation of the guides from a disability and accessibility standpoint.  相似文献

Racial microaggressions are subtle, derogatory messages conveyed to people of color. While often delivered unconsciously, these persistent and pervasive negative messages can have devastating effects on individuals and organizations. In an effort to investigate academic librarians’ experiences and observations of racial microaggressions, a survey was sent to three ACRL listservs in the spring of 2012. In a preliminary analysis of the 129 comments left by survey participants, seven themes were identified: microassaults, microinsults, microinvalidations, environmental microaggressions, uncertainty or racism not observed, being excluded or isolated, and implications for recruitment and retention.  相似文献

Systemising is the drive to analyse or construct systems, and can be assessed by a systemising quotient (SQ). Empathising is the drive to identify mental states and respond with an appropriate emotion, and can be assessed by an empathising quotient (EQ). Previous evidence suggests that: (1) males are more drawn to systemise than females, and females are more drawn to empathise than males; and (2) males are more likely to work in science and engineering, or to study science subjects at university. This study found: (1) males score more highly on the SQ, and females score more highly on the EQ; (2) controlling for age and gender, there is an association between degree subject and SQ and EQ scores, with “scientists” scoring higher on the SQ and “artists” scoring more highly on the EQ; and (3) individuals’ scores on EQ and SQ were better predictors of degree subject than gender.  相似文献
