Emotional and behavioral correlates of Type A behavior in children and adolescents were examined in 184 fifth-, seventh-, and ninth-grade students, classified as high or low Type A, using self-report, teacher ratings (fifth grade only), and structured interview procedures. Measures included the Hunter-Wolf A-B Rating Scale, Behavioral Symptoms of Stress Inventory, Dimensions of Temperament Survey, Desire for Control Scale, Eysenck Personality Inventory, and the Multiple Affect Adjective Checklist. High Type A children reported significantly more stressed-related behaviors, higher levels of depression, anger, anxiety, and cognitive disorganization, and greater reactivity than Low Type A. No differences were found on measures of temperament (activity level, attention span, adaptibility, and rhythmicity), desire for control, or introversion-extroversion. Females, in general, reported significantly more behavioral stress symptoms. However, no other gender differences were found. Possible reasons for reported differences between Type A children and adults are discussed, along with gender differences in behavioral symptoms. Need for multiple measures of Type A across situation is considered along with need for controlled longitudinal studies of Type A components and the influence of contexts.Received Ph.D. from Stanford.

The reality of cloning and stem cell research has provoked wonder, fear and anger. These developments have the potential fundamentally to alter humanity. But how well informed is the range of views being expressed? Is progress being threatened by understandable but uninformed fears? Or are scientists rushing toward an ethical abyss, so concerned with what they can do that they never stop to ask what they should do? This article identifies some of the fears and hopes surrounding cloning and stem cell research. It aims to provoke ethical debate in evaluating such research. 相似文献

Mitochondrial DNA (mtDNA) analysis of forensic samples typically is performed when the quantity and quality of DNA are insufficient for nuclear DNA analysis or when maternal relatives may be the only reference source. Many of the steps required in the analytical process are both lengthy and labor intensive. Therefore, improvements in the process that reduce labor without compromising the quality of the data are desirable. The current procedure requires purification of the amplicons by centrifugal filtration after PCR and prior to cycle sequencing. Because this method requires several manipulations to perform, alternate cleanup procedures were investigated. These include the use of 1) Qiagen QlAquick PCR Purification columns, 2) Concert Rapid PCR Purification columns, and 3) ExoSAP-IT reagent. When the yield of purified amplicons, quality of the sequence profile, and ease of assay were evaluated, the use of ExoSAP-IT reagent for post-amplification purification was chosen to replace the filtration method. 相似文献

Mediators, called night correspondents, have been hired by some French municipalities to reduce violence in the neighborhoods, using dialogue and daily help (in repairing things in particular). Night correspondents seem to be especially appropriate to reduce incivility, i.e. daily nonrespectful behavior. This essay reports on the results of two surveys conducted in Cergy by MBA students of two seminars at ESSEC business school. Although the recommendation of hiring night correspondents has not been followed yet in Cergy, several decisions have been taken by the social lessors and other public actors in the neighborhoods aimed at reducing violence, through mediation processes. 相似文献

Six ninhydrin analogues containing oxygen, sulfur, and selenium substituents at the C-5 position, 5-(4-nitrophenyl)ninhydrin, and benzo[f]furoninhydrin were evaluated as fingerprint development reagents. The analogues all showed good fingerprint color development but were not superior to ninhydrin in this respect. The benzo[f]furoninhydrin complex was strongly luminescent at room temperature following zinc complexation, while the remaining analogues required cooling to -196 degrees C to produce optimum luminescence. The benzo[f]furo, nitrophenyl, and methyl selenide analogues showed the best potential as fingerprint reagents with the benzo[f]furo analogue comparing favorably with DFO. 相似文献

Self-report questionnaires are frequently used in youth research, but doubt remains whether total anonymity affects the results. This study compared the responses of 704 mainly 16–17-year-old adolescents to self-report measures of various health indicators in 2 groups: anonymous and confidential collection. For most health indicators no significant differences were found. Perceived health, use of alcohol, and aggressive behavior (for boys) were reported significantly less frequently in the confidential group (small effect size). It appeared that pupils with high scores on social desirability do not respond differently at most health indicators in the 2 conditions. For most health characteristics, epidemiologically useful outcomes may be derived from confidential self-report measures, which are also valuable for detecting individual at-risk children. Similar studies in lower grades and other types of education should confirm the results.Youth Department, Municipal Health Service Rotterdam area.

We elucidate a powerful yet simple method for deriving comparative statics conclusions for a wide variety of models: Monotone Comparative Statics ( Milgrom and Shannon 1994 ). Monotone comparative static methods allow researchers to extract robust, substantive empirical implications from formal models that can be tested using ordinal data and simple nonparametric tests. When these methods apply, they can replace a diverse range of more technically difficult mathematics (facilitating richer, more realistic models), assumptions that are hard to understand or justify substantively (highlighting the political intuitions underlying a model's results), and a complicated set of methods for extracting implications from models. We present an accessible introduction to the central monotone comparative statics results and a series of practical tools for using these techniques in applied models (with reference to original sources, when relevant). Throughout we demonstrate the techniques with examples drawn from political science . 相似文献

On 30 September 1996 the U.S. Advisory Commission on IntergovernmentalRelations (ACIR) closed its doors, ending thirty-seven yearsof advocacy for federalism and intergovernmental relations.A majority of members in the Congress felt that A CIR had becomeirrelevant to the issues facing them and agreed that littlewould be lost by terminating the commission. The Clinton administration,although supportive until near the end, withdrew its'supportout of displeasure with the commission's handling of the unfundedfederal mandates issue. The national associations representingstate and local governments were ambivalent. ACIR was no longerlooked to for solutions to the nation's intergovernmental relationsproblems. With the exit of ACIR, the federal government's lastresource for addressing broad intergovernmental issuesbeyondthe confines of individual programsis gone. 相似文献
