Development implies goals and the positing of goals requires values. Economists have generally agreed that the increase of wealth (or perhaps welfare) is the proper object of economic development. Political scientists, probably happily, have no similar agreement in regard to the appropriate goal for political development. Moreover, it is doubtful that the various aspects of political change are located along a single continuum. This is an empirical question but investigation ought to begin at least with provision for an n‐dimensional space. Finally, political scientists should concentrate on political change that has too often been neglected in favour of economic and purely social change. 相似文献

This article examines the impact and magnitude of underinvestment in the public infrastructure of the economy of the United States, and points to its implications for deficit reduction and economic growth. It becomes evident that the lack of both a complete inventory of infrastructure investment needs and a coherent future investment strategy at the federal level have led to a situation where the volume of public works investment in the United States has fallen critically short of what may be considered an optimum level. Recognizing the limitations of capital budgeting, a management perspective is taken in which increased planning and policy development at the national level emerge as necessities in achieving the type of results required to enhance economic growth and responsibly reduce the national deficit. 相似文献

Inverse Productivity or Inverse Efficiency? Evidence from Mexico 总被引:2,自引:0,他引:2
Using a unique panel data set from rural Mexico, we find strong evidence of a negative relationship between farm size and both productivity and technical efficiency: large farms not only have a lower value of output per hectare than small farms, they also produce further from the efficiency frontier. Our findings suggest that, in spite of the ongoing transformation of agricultural supply chains and economists’ recommendations for small farmers to exit crop production, there may be sustained advantages for smallholder farms. Our analysis offers new insights into inverse-farm size relationship, the productivity–efficiency relationship, and the use of stochastic frontier techniques. 相似文献

The story of the founding of the Communist Party of China (CPC) in 1921 is one of humble beginnings, when China was in shambles, dominated by foreigners, semi-feudalist, impoverished and run by corrupt warlords. Meeting in a traditional shikumen house in Shanghai, 13 men dedicated to the purpose of carrying out a Marxist-Leninist revolution designed to end imperialism within China and bring about both modernity and prosperity to the Chinese people, would change the course of China and the world forever. They believed that China had to change and that the Party was the instrument to achieve that change. 相似文献

The opioid epidemic has affected the United States (US) for decades with fentanyl and its analogs accounting for a recent surge in morbidity and mortality. Currently, there is a relative lack of information characterizing fentanyl-related fatalities specifically in the Southern US. A retrospective study was conducted to examine all postmortem fentanyl-related drug toxicities in Travis County, Texas, encompassing Austin (one of the fastest-growing cities in the US), from 2020 to 2022. Fentanyl contributed to 2.6% and 12.2% of deaths submitted for toxicology between 2020 and 2022, respectively, representing a 375% increase in fentanyl-related deaths over this 3-year period (n = 517). Fentanyl-related fatalities primarily occurred in males in their mid-30s. Fentanyl and norfentanyl concentrations ranged from 0.58 to 320 ng/mL and 0.53 to 140 ng/mL with mean (median) concentrations of 17.2 ± 25.0 (11.0) and 5.6 ± 10.9 (2.9) ng/mL, respectively. Polydrug use was present in 88% of cases, with methamphetamine (or other amphetamines) (25%), benzodiazepines (21%), and cocaine (17%) representing the most frequently identified concurrent substances. Co-positivity rates of various drugs and drug classes widely varied over time. Scene investigations reported illicit powder(s) (n = 141) and/or illicit pill(s) (n = 154) in 48% (n = 247) of fentanyl-related deaths. Illicit oxycodone (44%, n = 67) and illicit “Xanax” (38%, n = 59) pills were frequently reported on scene; however, toxicology only identified oxycodone and alprazolam in 2 and 24 of these cases, respectively. The results of this study provide a better understanding of the fentanyl epidemic in this region creating an opportunity to promote increased awareness, shift focus to harm reduction, and aid in minimizing public health risks. 相似文献

The Effect of pH on Electrolyte Detection of Fingermarks on Cartridge Cases and Subsequent Microscopic Examination 下载免费PDF全文
Simon Liu H.B.Sc. Michelle Pflug H.B.Sc. Robert Hofstetter H.B.Sc. B.A. Michael Taylor 《Journal of forensic sciences》2015,60(1):186-192
Cartridge cases may contain deposited fingermarks when the firearm was loaded ( http://www.nij.gov/pubs-sum/225320.htm , J Forensic Sci, 53 , 2008 and 812). Cartridge cases can be individualized with microscopic examination. However, heat and friction degrades the deposited fingermark on the fired cartridge cases, if any on the surface. Also, unfired and fired cartridge cases are made of metal, which is a nonporous surface that does not retain fingermarks well ( http://www.nij.gov/pubs-sum/225320.htm ). This study tests the effects of pH level on fingermark clarity on brass fired and unfired cartridge cases and microscopic striation examination (MSE). Two trials were performed to determine the optimal pH in fingermark clarity for both types of cartridges. This was performed through immersion in six pH range solutions from dilutions of sulfuric acid and sodium hydroxide for 24 h for the purpose of enhancing the fingermarks on the metal. The use of the optimal neutral pH level is suggested because immersion of the cartridge cases in pH 1–3 and 3–5 affects MSE. 相似文献

Assessing the effectiveness and efficiency of a police service: the analytics of operational reviews
Curt Taylor Griffiths Nahanni Pollard Tom Stamatakis 《Police Practice and Research》2015,16(2):175-187
Concerns over rising costs have forced police services to balance increasing fiscal and operational pressures. Discussions of the resources and requirements of police, however, are generally only informed by political expediency and traditional practice. Operational reviews (ORs) can be used to document the demands on police, their capacity to respond, and ways in which they can become more efficient and effective. Drawing on an OR of a major urban Canadian police service, this article provides a broad outline of the components of an OR and the analytics that can be used to answer these key questions. 相似文献

In this paper, we focus on a policy trial that was undertaken in a complex and controversial policy field (Indigenous community development), with the avowed objective of learning from experience in the field . We observe that despite significant implementation effort and quality evaluation, little systematic policy learning occurred. Four impediments are identified: (i) the policy environment was highly politicized and contested, (ii) the results challenged accepted ways of working, (iii) there were no systematic processes for policy learning to occur, and (iv) the learnings were distorted by inter‐agency competition and associated ‘labelling’. We suggest that, in controversial policy fields, the most useful first step in enhancing evaluation‐use is for bureaucracies to institute systematic processes for evaluation findings to be considered, with the aim of elaborating ‘what works’ into a consensual approach to change. Without change of this kind, evaluation‐use will remain a failed area of policy. 相似文献
