High performance liquid chromatographic determination of alcohols with reference to body distribution of methanol

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.

国家权利·国家被害·国家护卫需求

国家权利是国家就维持其存在和履行职能所应有利益而享有的一种支配自由。国家也会受到犯罪的侵害 ,国家被害的客体是国家权利。国家权利也有防御犯罪和利益补救的护卫需求。     

Job Expectations and Career Goals of Title IV-E Child Welfare Social Workers with Varying Levels of Work Experience: How Do They Differ?

A comparison of three groups of Title IV-E child welfare workers revealed significant differences among all groups on job expectations and career goals. New workers reported most positive expectations for their jobs, and greatest interest in child welfare careers and in pursuing educational goals. Seasoned workers expressed least positive expectations and least interest in future child welfare careers and educational goals. Findings may assist universities in student selection and curriculum. Child welfare agencies may benefit in areas of recruitment, training, and policies. Realistic job previews might moderate high expectations for new workers and reduce unmet expectations for experienced workers.     

白族文化的包容性及其现实意义

包容性是白族文化最主要的特征之一。包容性几乎表现在白族文化的方方面面,但突出地表现在白族族源的多元性、白族文化源流的多源性、白族宗教信仰的多元性、南诏大理国与唐宋的关系、白族的民族观及婚俗观和丧葬观等方面;白族文化包容性的主要成因是受中原文化和白族生息的地理环境的影响;充分挖掘和利用白族文化的包容性有利于促进边疆民族地区的和谐社会建设。     

Autopsy findings in the eyes of fourteen fatally abused children

The eyes of fourteen fatally abused children and sixteen control cases were examined histopathologically. Ten of the abused children showed intraocular change. The most common ocular changes were subdural hemorrhage of the optic nerve and retinal hemorrhage which involved all the layers of the retina, but most commonly the nerve fiber layer, ganglion cell layer and inner nuclear layer. The presence of blood cavities within the retina partially supported the hypothesis of traumatic retinoschisis. The control cases of non-abused children rarely showed intraocular hemorrhage.

香港居民中的无国籍问题

<正> 香港一向为中国领土。由于英国150多年的殖民统治,由于香港本身国际都市化程度的加深,香港居民的国籍问题远较一般国家和地区复杂。这种情况将随1997年香港回归祖国的重大变化而更显突出。对香港居民而言,国籍问题关系到他们的切身利益,而处理得当与否也直接影响到香港的稳定繁荣,因此大有细加研究、妥善处理的必要。鉴于这一问题涉及面甚广,实践性、学术性都很强,非一两篇文章能够全面讨论清楚,这里仅就其中的一个较小层面——香港居民中的无国籍问题作一探讨,以期收抛砖引玉之效。     

Suicide in children and adolescents: a 10-year retrospective review

Suicide is second only to accidents as the most common cause of death for children and adolescents age 10 to 19 in Canada. All of the pediatric cases that were referred to the Hamilton Regional Forensic Pathology Unit from 1993 to 2002 were reviewed. For the purpose of this study, pediatric deaths were defined as deaths in the age group of 1 day up to and including 19 years of age. Specific criteria for suicide were applied to each case, independent of the manner of death issued by the coroner. The criteria were 3-fold. First, homicide had to be ruled out by the police investigation and autopsy findings. Second, the method had to be consistent with self-infliction. Finally, there had to be some evidence of suicidal intent. Questionable cases were discussed among the authors, and if reasonable intent could not be established, then the case was excluded. The autopsy and police reports were examined in detail regarding age, sex, location and method of suicide, presence of suicide notes, and any contributing psychologic factors or stressors. Of the 501 pediatric autopsies performed during the 10-year period, 31 (6%) met the criteria of suicide. The majority of cases (87%) were in older adolescents (age 15 to 19), and the male to female ratio was 2.4:1. Psychologic factors were identified in some of the cases, including depressed mood (77%), suicidal ideation (45%), previous suicide attempts (23%), and drug or alcohol problems (19%). Most of the suicides (61%) occurred in the victim's home, and 12 (39%) cases left a suicide note. In 9 cases (29%), alcohol or street drugs were detected postmortem, though in 8 cases toxicology was not performed. Hanging (48%) was the most common method of suicide, followed by firearms (13%), poisoning (10%), drowning (10%), and blunt force vehicular trauma (10%). Almost 60% of the male suicides were by hanging. No specific trend was identified in the 9 female suicides. These results were compared with similar studies within Canada and other countries. Overall, the method of suicide is dictated by what is convenient and readily available, though the acceptance of various suicide methods can change over time. Suicide prevention efforts should be tailored to address local trends.
