This article compares American, British, and Korean social enterprise policies to explore how government policy design shapes social enterprises and how “social benefit” and “public value” are defined. A social enterprise is defined as the legally structured organizational pursuit of blending social purpose and economic profit through business activities, and examples from each country are presented. Applying Bozeman's publicness theory, the authors demonstrate the wide range of roles that governments play in shaping social enterprises' ownership, funding, and control across the three countries using regulations, subsidies, and procurement policies. These roles may affect the impact of social enterprises in society. The case studies show that the U.S. approach to social enterprise policy is heavily market oriented, while the United Kingdom is in the middle of the market-to-publicness continuum, and South Korea is much closer to the publicness (government-dominated) end of the continuum.  相似文献

This case report describes a noncontact traffic accident involving a motor scooter and a tractor-trailer with a focus on the wind-drag effect. We used load cells to measure the drag force acting on a substantially similar motor scooter when a substantially similar tractor-trailer passes by it, taking into consideration various speeds of the tractor-trailer and distances between the two vehicles. A three-dimensional steady-state flow analysis was also performed by using the CFX program for computational fluid dynamics to examine the streamlines and the pressure distribution around the tractor-trailer at various speeds. From the experiment, for a separation distance of 1.0 m (3.28 ft) and a speed of 90 km/h (55.9 mph), the maximum resultant drag force is 124.5 N (28 lb); this constitutes a degree of force that could abruptly disrupt the stability in maneuvering by an operator who is unaware of the approaching tractor-trailer. In addition, a single equation that relates the tractor-trailer speed to the drag force that acts on the motor scooter was derived on the basis of the Reynolds number (Re) and the wind-drag coefficient (C(d)): C(d) = 1.298 × 10(-7) Re.  相似文献

Phenylalkylamine derivatives, such as methamphetamine (MA), amphetamine (AM), 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA), phentermine (PT), fenfluramine (FFA) and phenmetrazine (PM), and ketamine (KT) are widely abused recreational or anorectic drugs in Korea and are regulated under the Controlled Substance Act in Korea. Phenylalkylamines and ketamine analysis is normally performed using both urine and hair samples but there is no established method for the simultaneous analysis of all these phenylalkylamines and ketamine in oral fluids. Oral fluid is easy to collect/handle and can provide an indication of recent drug abuse. In this study, to confirm the presence of phenylalkylamine derivatives and ketamine in oral fluid after screening with an immunoassay, an analytical method using automated solid phase extraction (SPE) and gas chromatography-mass spectrometry (GC-MS) was developed and fully validated according to international guidelines. The applicability of the assay was demonstrated by analyzing of authentic oral fluid samples and the results of oral fluid analysis were compared with those in urine and hair to to evaluate the feasibility of oral fluid in forensic cases. The recovery of phenylalkylamines and ketamine from oral fluid collection devices was also assessed. Oral fluid specimens from 23 drug abuse suspects submitted by the police were collected using Salivette (Sarstedt, Nümbrecht, Germany), Quantisal (Immunalysis, Pomona, CA) or direct expectoration. The samples were screened using a biochip array analyzer (Evidence Investigator, Randox, Antrim, UK). For confirmation, the samples were analyzed by GC-MS in selected-ion monitoring (SIM) mode after extraction using automated SPE (RapidTrace, Zymark, MA, USA) with a mixed-mode cation exchange cartridge (CLEAN SCREEN, 130 mg/3 ml, UCT, PA, USA) and derivatization with trifluoroacetic anhydride (TFA). The results from the immunoassay were consistent with those from GC-MS. Twenty oral fluid samples gave positive results for MA, AM, PT and/or PM among the 23 cases, which gave positive results in urine and/or hair. Although large variations in the MA, AM, PT and PM concentrations were observed in three different specimens, the oral fluid specimen was useful for demonstrating phenylalkylamines and ketamine abuse as an alternative specimen for urine.  相似文献

This study assessed the effect of a 10‐week cognitive behavior treatment program in 30 mentally ill sex offenders. The effect of the program was evaluated using the Interpersonal Responsiveness Index (IRI), UCLA Loneliness Scale (UCLALS), Coping Using Sex Inventory (CUSI), and Rape Myth Acceptance Scale (RMAS). Data were analyzed using the paired t‐test. The ability of sex offenders to cope with sexual acts when they faced stressful situations and to accept the rape myth was significantly improved on CUSI (= 2.09, = 0.04) and RMAS (= 5.45, < 0.001). Feelings of isolation and the ability to empathize based on IRI (= 0.62, = 0.54) and UCLALS (= 0.88, = 0.38) were not significantly improved. To prevent recidivism, treatment for mentally ill sex offenders should focus on changes in their cognitive and emotional characteristics in addition to their main psychiatric illness.  相似文献

This article seeks to understand the ways in which urban livelihoods are affected by development-induced displacement, with a particular focus on residents remaining in the locality. Through an empirical case study of a railway upgrading project in Metro Manila, the article investigates livelihood impacts of large-scale demolition and displacement, which varied depending on whether the physical capital of remaining residents declined due to land clearance and the extent to which they relied on the local livelihood network established with displaced settlers. In comparison, households remained intact when they had little engagement with the local informal economy.  相似文献

This study investigates the question of why democracies are more likely to win wars than non-democracies. I argue that due to the transparency of the polities, and the stability of their preferences, once determined, democracies are better able to cooperate with their partners in the conduct of wars, and thereby are more likely to win wars. In support of my argument, the main findings in this study show that, other things being equal, the larger the number of democratic partners a state has, the more likely it is to win; moreover, democratic states are more likely to have democratic partners during wars. These results are in contrast with those in current literature about the high likelihood of prevailing by democracies in wars, which emphasize, on the one hand, the superior capacity of democratic states to strengthen military capabilities and, on the other hand, to select wars in which they have a high chance of winning.  相似文献

The current study examines how the incumbent government's economic performance plays a role in mediating the impact of political corruption on electoral outcomes in 115 developing countries with relatively higher levels of corruption than Western consolidated democracies. Borrowing theoretical insights from the information-processing theory of voting, this study finds that political corruption becomes a formative electoral factor when the regime fails to sustain a sufficient level of economic growth. Otherwise, political corruption is not a significant factor that shapes electoral outcomes, irrespective of the level of perceived corruption, because the economy occupies voters' minds as the most important issue, making it a more accessible issue than political corruption.  相似文献

Abstract

Given that statism has been so intensively reviewed recently, it is reasonable to ask why there is a need to produce another review. The key lies in the nature, not the quantity, of the previously published reviews. A survey of the existing literature shows that most of the reviewers are loyalist critics whose goal is to build statism as a new paradigm of Asian political economy. Emphasizing statism's contribution in expanding the debate on Newly Industrializing Countries (NICs) beyond the market-centric analysis, they offer opinions on this theory that are positive—not surprisingly—and on the whole even generous. Misled by statism's anti-market rhetoric, some writers from a more critical tradition have also embraced statism as a new departure for studies of Asian capitalist development. Consequently, statism has escaped a rigorous scrutiny, which is long overdue.  相似文献

Under the doctrine of vicarious liability, a deep-pocket principal is often held responsible for a third-party harm caused by a judgment-proof agent’s negligence. We analyze the incentive contract used by the principal to control the agent’s behavior when a court can make an error in determining the agent’s negligence. We show that (1) reducing the error of declaring the agent not negligent even when he was (pro-defendant or type II error) is better than reducing the error of declaring the agent negligent even when he was not (pro-plaintiff or type I error) and (2) allowing the principal to penalize the agent even when the court declares the agent not negligent improves welfare. The latter supports the argument that causing an accident (or a reliable allegation of misconduct) should be sufficient to justify a “just cause” termination of an employee.  相似文献
