以法律"化"道德之初探

道德和法律作为社会控制的两种手段,它们相互之间究竟何者居于主导地位,取决于二者与现实联系的紧密程度,而正是当代中国社会的现实发展状况和中国社会伦理道德领域本身所呈现出的混乱状态,决定了中国的法律与道德之间的这种引导与被引导、型塑与被型塑的关系。“以法律化道德”就是要以现代法治的基本精神来引导和重塑转型时期当代中国伦理道德。     

CD19-positive acute myeloblastic leukemia with trisomy 21 as a sole acquired karyotypic abnormality

We report that a 63-year-old Chinese female had acute myeloblastic leukemia (AML) in which trisomy 21 (+21) was found as the sole acquired karyotypic abnormality. The blasts were positive for myeloperoxidase, and the immunophenotype was positive for cluster of differentiation 19 (CD19), CD33, CD34, and human leukocyte antigens (HLA)-DR. The chromosomal analysis of bone marrow showed 47,XX,+21[2]/46,XX[18]. Fluorescent in situ hybridization (FISH) showed that three copies of AML1 were situated in separate chromosomes, and that t(8;21) was negative. The patient did not have any features of Down syndrome. A diagnosis of CD19-positive AML-M5 was established with trisomy 21 as a sole acquired karyotypic abnormality. The patient did not respond well to chemotherapy and died three months after the diagnosis. This is the first reported case of CD19-positive AML with trisomy 21 as the sole cytogenetic abnormality. The possible prognostic significance of the finding in AML with +21 as the sole acquired karyotypic abnormality was discussed.     

Short-Term Memory Trace Decay in Kinesthetically Monitored Force Reproduction

Abstract

The decay of the memory trace for intervals of 1/2 min., 1 1/2 min., and 4 min. between the test stimulus and the reproduction trial was studied for a force reproduction task in which the amount of movement was very small, .13 in. The subject pushed against a handle attached to the top of a steel bar with the preferred hand. Sixty-three women volunteers from college physical education classes performed the experiment. For Part A all subjects first had four trials in which the reproduction was immediate (the control condition). Then they were divided randomly into three subgroups of 21, and each subgroup was assigned to one of the three retention intervals (experimental conditions) for four more trials. In Part B the whole experiment was repeated. For both absolute and algebraic error, analysis of covariance indicated no significant differences at the .05 level among the experimental conditons. Also, no significant differences were found comparing a condition in Part A with its respective condition in Part B. While there were no significant differences between control and experimental conditions for absolute error, significant differences were found for algebraic error. The algebraic error changed from considerable overestimation upon immediate reproduction to only slight overestimation after a 1/2-min. retention interval.     

Effect of Practice on True Score and Intra-Individual Variability for Reaction and Movement Times for Simple and Complex Movements

Abstract

The effect of practice on individual differences and intra-individual variability in reaction and movement times were studied for simple and complex, discrete, motor tasks. Changes with practice for intertrial correlations of adjacent trials and the effects of an increasing number of interpolated trials on intertrial correlations were also observed. For both tasks and for both reaction and movement times, the intra-individual variability decreased with practice. The true score variability for reaction time on both tasks and for movement time on the simple task shows little change with practice. On the complex task, true score variability for movement time decreases with practice. For movement time, adjacent trial correlations increase during the early practice trials then remain stable. For reaction time adjacent trial correlations increase throughout practice. Remoteness effects on intertrial correlations were found for both movement and reaction times for both tasks.     

Frequency Distributions and Standards of Anthropometric and Physical Performance Measures for College Women

Abstract

Frequency distributions of the records of a random selection of 200 college women in a nonmajor required program on anthropometric and physical performance measures commonly employed in physical education were compared with best-fitting normal curves for the same data. A table of random numbers was used to secure the sample. A percentile table for the various measurements was constructed. It was concluded that various measurements commonly employed by physical educators give a non-normal distribution. Hence, the obtained distribution as found on various measurements in this study does not warrant treating these data as normal.

Current studies on two separate topics: breastfeeding postpartum length of hospital stay

IN THIS COLUMN, THE AUTHOR EXAMINES RECENT RESEARCH ON TWO SEPARATE TOPICS: 1) breastfeeding; 2) postpartum length of hospital stay. Recent studies suggest long-term effects of breastfeeding that benefit both mother and infant. Benefits include a reduced risk of breast cancer in breastfeeding mothers and a reduced level of total and LDH cholesterol in adults who were breastfed as infants. Infants of mothers with maternal asthma had lower rates of asthma if the mother breastfed. In a study of women in the United States who planned to breastfeed, those mothers who breastfed exclusively and planned to breastfeed more than three months were more likely to achieve their goals than mothers who planned to combine breast and human-milk substitute feeds and to breastfeed less than three months.In a Canadian study, shortened postpartum stays led to increased re-admission to hospital for mothers with cesarean births. In contrast, in a Massachusetts study, shortened postpartum stays did not lead to an increase in infant visits for urgent care. However, the Massachusetts study did not reflect a decrease in maternity-related costs associated with shortened length of postpartum stay.
