肝豆状核变性(Wilson病)治疗策略的变革及思考 总被引:1,自引:0,他引:1
评析肝豆状核变性(WD)当前的治疗方法,主要有低铜饮食,铜的螯合剂青霉胺及曲恩汀,锌制剂和四硫钼酸胺,肝移植。介绍WD治疗策略的变革:不再提倡驱铜疗法以去除堆积的铜,而是使血液中的游离铜离子浓度常态化以逆转铜中毒,并结合2007年《柳叶刀》WD治疗专家共识进行思考。最后,展望未来对WD可能的根治疗法,即基因治疗、肝细胞移植及现在可施行的肝移植。 相似文献

考察解题反思对数学学业优生和差生解题结果及所用策略的不同影响。选取初一至初三年级的数学学业优生和差生为被试,以一套连加数问题为实验材料,进行一对一的测试,前后进行两次测试。对反思组优差生(优生12人,差生10人)和无反思组优差生(优生14人,差生14人)解题过程的比较,发现:1)解题后立即进行反思能够提高差生的解题正确率,但是延长解题时间;2)先前的解题反思对优生和差生后续解题时的正确率和解题时间均不产生明显影响;3)解题后立即进行反思能够促进优生和差生使用高效策略,放弃低效策略;4)先前的解题反思在后续解题中仍然促进学生使用高效策略,对优生的促进作用比对差生更明显。 相似文献

制造行业管理胜任力与绩效关系的实证研究 总被引:2,自引:0,他引:2
通过对571名制造型企业管理者的问卷调查,探索并验证了制造业管理胜任力结构维度,检验了不同背景因素对管理胜任力的影响。结果表明:制造业管理胜任力具有六维结构,包含22个指标,其信度和效度较好;不同管理层次的管理者在制造过程控制和市场营销策划维度上的评价有显著性差异,不同企业规模下的管理者在行业核心理念和产品系统管理维度上的评价有显著性差异;产品系统管理与市场营销策划能力对制造业管理者绩效有良好的预测力。同时发现,制造业管理胜任力不能较好地解释周边绩效的变异量。 相似文献

Did Beethoven and Mozart have more in common with each other than Clapton and Hendrix? The current research demonstrated the widely reported Mozart Effect as only partly significant. Event-related brain potentials (ERPs) were recorded from 16 professional classical and rock musicians during a standard 2 stimulus visual oddball task, while listening to classical and rock music. During the oddball task participants were required to discriminate between an infrequent target stimulus randomly embedded in a train of repetitive background or standard stimuli. Consistent with previous research, the P3 and N2 ERPs were elicited in response to the infrequent target stimuli. Own genre preference resulted in a reduction in amplitude of the P3 for classical musicians exposed to classical music and rock musicians exposed to rock music. Notably, at the pre-attentive stage of processing (N2) beneficial effects of exposure to classical music were observed for both groups of musicians. These data are discussed in terms of short and long-term music benefits on both conscious and unconscious cognitive processes. 相似文献

We compared two formats for optional study sessions offered to students in a research methods course. Study sessions alternated
between a game format (e.g., Behavioral Jeopardy) and a student-directed question and answer format, presented in counterbalanced
order across different sections of the same course. The results of the alternating treatments design in Study 1 indicated
that, despite improvements in quiz performance relative to baseline, there were no consistent differences between the two
formats on attendance at the study sessions or on weekly quiz performance. Similar results were obtained in a systematic replication
(Study 2) in which opportunities to respond to game questions were equated across study sessions. 相似文献

Diagnosis and treatment of cancer has been associated with both posttraumatic stress disorder (PTSD) symptoms and posttraumatic
growth (PTG). This cross-sectional study sought to assess the frequency, common predictors, and interrelationships of PTSD
symptoms and PTG in breast cancer survivors (n = 65). In this sample, symptoms of PTSD and reports of PTG were common and were not significantly related to one another.
Greater social constraints on talking about breast cancer and perception of cancer as a traumatic stressor were associated
with greater PTSD symptomatology. Younger age and perception of cancer as a traumatic stressor were associated with greater
PTG. Findings suggest the central role of subjective appraisal in adjustment to cancer. Psychosocial interventions should
be sensitive to the potential for PTG, both in treatment design and in assessment of outcomes. 相似文献

It has long been argued that stigmatized individuals can ultimately internalize the stereotype alleging their inferiority. The present article investigated whether the internalization of the reputation of math inferiority that targets women can affect their math performance and whether this influence is caused by a disruption of working memory. A first study showed that stereotype endorsement had a significant impact on women’s statistic performance by lowering their self-evaluation of math ability even when controlling for prior achievement. A second study was designed to assess the possibility that the lower math performance displayed by women with low self-evaluation of math ability was due to interference in working memory. Using a dual task paradigm, this study showed that indeed women with low math self-evaluation displayed more errors and spent more time solving additions than women with high math self-evaluation, but mainly on difficult items of the dual task. The findings, which are congruent with an explanation in terms of a temporary disruption of working memory, are discussed. 相似文献

Ethical guidelines require school psychologists to ensure that their assessment practices are nondiscriminatory, but typical discussions on this topic neglect the possible discriminatory effects of cultural stereotypes on assessment results. Recent research on stereotype threat shows that students' knowledge of stereotype-based negative expectations about their test performance can depress their actual test performance. This paper discusses the range of conditions that promote stereotype threat and identifies important moderators and mediators of the phenomenon. Several practical suggestions are offered for school psychologists to consider when interviewing students, interpreting assessment results, and developing programs to increase schoolwide achievement. 相似文献

This article assesses the significance of Baker et al., Equality: from Theory to Action from the perspective of current concerns occupying legal equality scholars in the UK, focusing in particular on the practical
relevance of equality studies to the kinds of issues arising from the debate over the new Commission for Equality and Human
Rights (CEHR). The article highlights and considers key issues, including the delineation of the sphere of inequality protection,
the normative content of the concept of equality espoused by law and the potential of law to reach beyond its current limits
to embrace the broader dimensions of (in)equality identified in Baker et al.’s account. 相似文献
