Pete Maravich's incredible heart

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding.     

Comparison of fingernail striation patterns in identical twins.

The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images.     

关于公司与企业法人几个问题的分析--由《公司法与公司治理结构认识误区》一文引起的思考

本文认为 ,公司的本义在于资本所有权的联合 ,但公司作为法人企业则应同时具备独立地享有和支配公司全部资产、并独立地对外承担民事责任的能力。由此 ,本文对股份合作制企业、夫妻型公司、一人公司、有限责任和多人代表制度等问题逐一作了分析。另外 ,本文提出了从归属和权能两个方面界定公司资产所有权的思路。认为 ,从最终归属上 ,企业的资产所有权属于股东 ;但在权能方面 ,企业资产的所有权则为股东与公司分别享有。股东的权能主要体现为收益 ,公司的权能主要体现为对企业资产的占有、使用和处分。因此 ,国有企业的法人地位与其资产所有权的全民性质并不矛盾。

Scales for perceived risk of student-on-student victimization in grades 7 through 10: A psychometric analysis of the adolescent index on school safety

Although past research has developed scales for the incidence, prevalence, and fear of student-on-student victimization (SSV), little is known about the scaling of perceived risk (i.e., the cognitive appraisal of the chances of experiencing SSV). Hence, this study examined self-report survey data for the perceived risk of SSV as measured in the Adolescent Index for School Safety (AISS). Children in grades 7 through 10 (n=337) in a single Florida public school completed the AISS. Factor analyses using Maximum Likelihood Estimation with Oblimin Rotation identified nine unique factors for perceived risk. Reliability analyses found standardized Cronbach Alphas that ranged from .64 to .91, and seven out of the nine identified scales were above .80, which suggested good to excellent internal consistency. Future research should examine the content validity, construct validity, and predictive validity for the AISS and other self-report surveys of SSV dynamics.

Forensic psychiatry and malpractice

This paper concerning the last 87 malpractice cases referred to the Department of Psychiatry and Law, Menninger Clinic, includes 57 suits against mental health practitioners and/or institutions, and 30 nonpsychiatric suits against general hospitals, surgeons, obstetricians, etc. A patient was available for interview in only 12 percent of the psychiatric cases; in 88 percent we reviewed medical records and consulted with attorneys. In the psychiatric cases the crucial question was whether a generally accepted standard of care was breached. The inherent problems of applying appropriate criteria to standards of care by practitioners and institutions are discussed. In half the psychiatric cases we found no significant deviation from acceptable clinical performance; in half we concluded that negligent practice had occurred. We did see a litigant for evaluation in 90 percent of the nonpsychiatric cases. The main issue involving them concerned harm or disability related to presumed negligence by medical personnel. How we evaluate such cases and apply disability criteria is discussed.     

The extent of aspartic acid racemization in dentin: a possible method for a more accurate determination of age at death?

In the current study the objective was to find to what extent a reliable determination of age at death is made possible by establishing the degree of aspartic acid racemization in the dentin of teeth. The results of the investigation of 46 teeth are in agreement with the values found by other authors. The method presented makes a reproducible and accurate estimation of age possible. We intend to elaborate and improve this promising method for determination of age at death. The relevant points are presented here.
