New Public Management and Substantive Democracy 总被引:4,自引:1,他引:3
Richard C. Box Gary S. Marshall B.J. Reed & Christine M. Reed 《Public administration review》2001,61(5):608-619
The authors are concerned that a remaining refuge of substantive democracy in America, the public sector, is in danger of abandoning it in favor of the market model of management. They argue that contemporary American democracy is confined to a shrunken procedural remnant of its earlier substantive form. The classical republican model of citizen involvement faded with the rise of liberal capitalist society in the late nineteenth and early twentieth centuries. Capitalism and democracy coexist in a society emphasizing procedural protection of individual liberties rather than substantive questions of individual development. Today's market model of government in the form of New Public Management goes beyond earlier "reforms," threatening to eliminate democracy as a guiding principle in public-sector management. The authors discuss the usefulness of a collaborative model of administrative practice in preserving the value of democracy in public administration. 相似文献

Although forensic examiners operate in a stressful environment, there is a lack of understanding about workplace stress and feedback. These organizational and human factors can potentially impact forensic science judgments. In this study, 150 practicing forensic examiners from one laboratory were surveyed about their experiences of workplace stress, and the explicit and implicit feedback they receive. Forensic examiners reported that their high stress levels originated more from workplace-related factors (management and/or supervision, backlogs, and the pressure to do many cases) than from personal related factors (family, medical, and/or financial). The findings showed that a few (8%) of the forensic examiners sometimes felt strong implicit feedback about what conclusions were expected from them and that some (14%) also strongly felt that they were more appreciated when they helped to solve a case (e.g., by reaching a “match” as opposed to an “inconclusive” conclusion). Differences were found when comparing workplace stress and feedback levels across three core forensic science fields (forensic biology, chemistry, and latent prints) and across career stages (early, mid, and late). Gaining insights into the stress factors within a workplace and explicit and implicit feedback has implications for developing policies to improve the well-being, motivation, and performance of forensic examiners. 相似文献

There is currently no published empirical evidence‐base demonstrating 3D printing to be an accurate and reliable tool in forensic anthropology, despite 3D printed replicas being exhibited as demonstrative evidence in court. In this study, human bones (n = 3) scanned using computed tomography were reconstructed as virtual 3D models (n = 6), and 3D printed using six commercially available printers, with osteometric data recorded at each stage. Virtual models and 3D prints were on average accurate to the source bones, with mean differences from ?0.4 to 1.2 mm (?0.4% to 12.0%). Interobserver differences ranged from ?5.1 to 0.7 mm (?5.3% to 0.7%). Reconstruction and modeling parameters influenced accuracy, and prints produced using selective laser sintering (SLS) were most consistently accurate. This preliminary investigation into virtual modeling and 3D printer capability provides a novel insight into the accuracy of 3D printing osteological samples and begins to establish an evidence‐base for validating 3D printed bones as demonstrative evidence. 相似文献

This study examined reciprocal relationships between adolescents’ perceptions of parental nurturance and two types of adolescent
aggressive behaviors (indirect and direct aggression) using a transactional model. Three waves of longitudinal data were drawn
from the Canadian National Longitudinal Survey of Children and Youth. The sample included 1,416 (735 female) adolescents who
were 10- and 11-year-olds at Time 1 and became 14-and 15-year-olds at Time 3. The findings failed to support reciprocal effects,
but confirmed parental effects at different ages for girls and boys. For girls, perceptions of parental nurturance at age
10 were negatively associated with both indirect and direct aggression at age 12. For boys, perceptions of parental nurturance
at age 12 were negatively associated with both aggressive behaviors at age 14. Future research should continue to investigate
reciprocal effects in parent-adolescent relationships to identify developmental periods where the effect of adolescents’ or
their parents’ behavior may be stronger. 相似文献

A 19-year-old G1P0 Caucasian woman died 8 days postpartum because of the subinvolution of the uteroplacental arteries. Microscopic examination of the placental implantation site revealed large, dilated spiral arteries containing partially occluding thrombi in the superficial myometrium. The presence of cytotrophoblasts within and surrounding the spiral arteries was confirmed by low molecular weight cytokeratin immunohistochemistry. Infection of the Cesarean section incision site was demonstrated by the growth of Staphylococcus aureus and Streptococcus agalactiae Group B in the wound as well as the intrauterine blood clot. Although subinvolution of the placental site may be a cause of delayed postpartum hemorrhage and significant morbidity, the underlying pathophysiologic mechanism is unknown. 相似文献

Suicide by asphyxiation using helium is the most widely-promoted method of "self-deliverance" by right-to-die advocates. However, little is known about persons committing such suicides or the circumstances and manner in which they are completed. Prior reports of suicides by asphyxiation involving helium were reviewed and deaths determined by the North Carolina Office of the Chief Medical Examiner to be helium-associated asphyxial suicides occurring between January 1, 2000 and December 31, 2008 were included in a new case series examined in this article. The 10 asphyxial suicides involving helium identified in North Carolina tended to occur almost exclusively in non-Hispanic, white men who were relatively young (M age = 41.1 T 11.6). In 6 of 10 cases, decedents suffered from significant psychiatric dysfunction; in 3 of these 6 cases, psychiatric disorders were present comorbidly with substance abuse. In none of these cases were decedents suffering from terminal illness. Most persons committing suicide with helium were free of terminal illness but suffered from psychiatric and/or substance use disorders. 相似文献
