本文以笔者在泰国曼谷对潮人群体田野调查时所得的问卷资料和口述材料为基础,试图对泰国潮人群体的认同情况进行研究。本文认为,文化认同对海外潮人的认同起主导作用,受访者对华人文化尤其是潮汕亚族群文化有较强的认同感。     

Wind-drag estimation in a traffic accident involving a motor scooter and a tractor-trailer

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.     

Effect of Sex Offenders Treatment Program on Cognitive and Emotional Characteristics of Mentally Ill Sex Offenders

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 (t = 2.09, p = 0.04) and RMAS (t = 5.45, p < 0.001). Feelings of isolation and the ability to empathize based on IRI (t = 0.62, p = 0.54) and UCLALS (t = 0.88, p = 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.     

Simultaneous analysis of psychotropic phenylalkylamines in oral fluid by GC-MS with automated SPE and its application to legal cases

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.

有组织型经济犯罪侦查对策探析

关于有组织型经济犯罪,理论界尚无过多的研究专著,而随着社会经济的发展,有组织型经济犯罪作为一种常见的经济犯罪形态严重地威胁着我国经济运行环境的健康发展。有组织犯罪应指三人以上为长期实施一种或多种犯罪获取某种巨大利益而建立的犯罪团体,有计划、有分工地故意实施依法应受刑事处罚的行为。有组织型经济犯罪具有法定性、牟利性、组织性、智能性、隐蔽性、复合性的特点。     

我国行政问责法制建设的思考

我国的行政问责制当前仍处于初级阶段,缺乏统一的、专门的行政问责法规制度,即便在已有的关于行政问责的具体规定中也存在不少缺陷。为此,行政问责法制建设必须加快立法步伐,完善相关配套制度,早日实现在整个国家范围内的行政问责法制化。     

Morphine in lymph nodes of heroin users

During the autopsy of heroin users, the most consistent morphologic finding is the enlargement of hepatic lymph nodes. Nodes from seven heroin addicts were analyzed for morphine and a concentration range of 0.02 to 0.87 mg/100 g was found. Morphine was detected in all of the nodes examined and the concentration was generally higher than that in the blood.     

Race, Bureaucratic Discretion, and the Implementation of Welfare Reform

This article explores the impact of the race of individual clients and of the local racial context on the implementation of sanctions for recipients of Temporary Assistance for Needy Families (TANF) in a Midwestern state. We find that although nonwhites are sanctioned at lower rates than whites overall, nonwhites are sanctioned more compared to whites in each local area. This paradox occurs because nonwhites tend to live in areas with lower sanction rates. Consistent with the literature on race and policy, we find that sanction rates increase as the nonwhite population increases until a threshold is reached where nonwhites gain political power .
