Few themes have aroused so much interest and contention as the search for environmental determinants of public policy. One major problem area in this debate concerns the identification of explanatory variables accounting for the cross-country variation in public expenditures. As no agreement has been reached about the basic issues involved, it seems appropriate to formulate a new approach to the problem of accounting for public finance patterns. An argument is presented to the effect that the employment of more rigorous econometric tools may help us draw an outline of the structural pattern behind the public household. The analysis indicates that we must abandon the idea of identifying stable structures that describe the relationships between the public household and the environment.  相似文献

This study reports on the results of a program evaluation of the U.S. Navy New Parent Support Program (NPSP). NPSP is comprised of two components: center-based parenting classes and home-based visits. Data are presented on: (a) satisfaction with program quality, (b) how well the program met its primary objectives (e.g., helps reduce parenting stress), (c) how well the NPSP met its Reasons for Being (RFBs; e.g., Helps service members concentrate on their job), and (d) program impact on mission-related outcomes (i.e., quality of life (QOL), readiness, and program impact on their decision to remain in the military). Results indicate that parents who take part in both the parenting classes and home-based visits report that the program exceeded their expectations, the program improved their perceptions of their parenting and coping skills, they perceived that the program demonstrated the Navy’s concern for Sailors and their families, and the program enhanced the family’s quality of life. Implications of study findings are discussed.

Mandatory data breach notification laws have been a significant legislative reform in response to unauthorized disclosures of personal information by public and private sector organizations. These laws originated in the state-based legislatures of the United States during the last decade and have subsequently garnered worldwide legislative interest. We contend that there are conceptual and practical concerns regarding mandatory data breach notification laws which limit the scope of their applicability, particularly in relation to existing information privacy law regimes. We outline these concerns here, in the light of recent European Union and Australian legal developments in this area.  相似文献

In forensic science, biological material is typically collected from evidence via wet/dry double swabbing with cotton swabs, which is effective but can visibly damage an item's surface. When an item's appearance must be maintained, dry swabbing and tape‐lifting may be employed as collection techniques that are visually nondestructive to substrates' surfaces. This study examined the efficacy of alternative swab matrices and adhesive lifters when collecting blood and fingerprints from glass, painted drywall, 100% cotton, and copy paper. Data were evaluated by determining the percent profile and quality score for each STR profile generated. Hydraflock® swabs, BVDA Gellifters®, and Scenesafe FAST? tape performed as well as or better than cotton swabs when collecting fingerprints from painted drywall and 100% cotton. Collection success was also dependent on the type of biological material sampled and the substrate on which it was deposited. These results demonstrated that alternative swabs and adhesive lifters can be effective for nondestructive DNA collection from various substrates.  相似文献
