William Robertson, director of the City of Los Angeles' Bureau of Street Services, is profiled here as an exemplary public administrator. The authors suggest that Robertson practices politics appropriately in his role in order to achieve great outcomes for his bureau, the citizens with whom he works, and the city as a whole. To adequately define the ways in which Robertson uses politics, Sherry Arnstein's "ladder of participation" is reconceptualized as a circle of participation in which Robertson uses multiple strategies of interaction with citizens, elected officials, employees, and peers. Lessons for public administrators are offered based on Robertson's example. 相似文献

Forensic toxicology laboratories are navigating a period of time with increasing drug overdose deaths, an opioid epidemic, the impact of the COVID-19 pandemic, and the illicit drug market flooded with novel psychoactive substances. In New York City, the Department of Forensic Toxicology has experienced a 56% increase in postmortem casework in the past decade with fentanyl detected in 80% of all overdose deaths. Over a period of 2.5 years, 15,638 postmortem cases were tested for the presence of fentanyl and fentanyl analogs using liquid-chromatography tandem mass spectrometry (LCMSMS). Fentanyl was detected in approximately one third of cases and of these 4447 cases with femoral blood. A twofold increase in cases with high concentrations of fentanyl (>100 ng/mL) was observed between 2021 and 2022. The minor metabolite and precursor chemical, 4-ANPP (4-anilino-N-phenethylpiperidine) may help differentiate between illicit and licit fentanyl. 4-ANPP blood concentrations were <10 ng/mL in 98% of the cases and the 4-ANPP:fentanyl ratio was <0.67 for 99.1% of blood specimens. Only six cases had 4-ANPP concentrations higher than the corresponding fentanyl blood concentration. This study also highlights, the changing fentanyl analogs found in postmortem cases since 2016 in NYC with the emergence of fluorofentanyl initially identified in 2020 and continuing to dominate in comparison with the prevalence of other analogs, many of which are no longer detected in casework. The detection of one of the latest drugs to be mixed with fentanyl, namely xylazine, has also increased in prevalence by 36.7% in 2022 compared with 2021. 相似文献

Does political uncertainty affect whether lobbyists contact government officials? We suggest that the answer depends on the type of uncertainty introduced. Distinguishing between policy objective uncertainty—where organized interests and lobbyists are uncertain about the policy intentions of decision makers—and issue information uncertainty—where policymakers are uncertain about the technical details of issues—we hypothesize that whereas an increase in policy objective uncertainty leads to a decrease in lobbying, a rise in issue information uncertainty leads to more lobbying. We test the hypotheses with longitudinal data from the Canadian Lobbyists Registry measuring change in the number of times lobbyists have contacted government ministries each month from 2008 to 2018. The results suggest that lobbying intensity does respond differently to these types of uncertainty. Whereas events introducing issue information uncertainty have a statistically significant positive relationship with lobbying, events introducing policy objective uncertainty do not. 相似文献
