采用S-P法检测17例HT患者甲状腺组织切除标本和9例正常甲状腺组织标本中ES、iNOS及bFGF的表达并分析其之间的相关性,以探讨三者在HT发生发展中的作用。结果HT组中ES、iNOS及bFGF的表达程度均明显高于正常组(P均〈0.05),其中ES与bFGF表达无显著相关性(P〉0.05),ES与iNOS、bFGF与iNOS的表达均呈显著正相关(r=0.531,r=0.723,P均〈0.05)。结论为在HT中,高表达的ES、iNOS及bFGF在其发生和发展中可能具有重要作用,为研究其病理生理变化和发病机理提供了理论依据。 相似文献

Background Cultural capital in families and especially, the educational level of parents, has during the last decades been found to be the most important dimension of socio‐economic influence on school performance. How the transmission of cultural capital over generations is concretized is however not yet fully investigated. Aims The aim is to unfold the influence of home background and more specifically, to reveal some important mediating factors between the educational levels of parents and the reading achievement levels of children. Sample Data comes from the Swedish participation in Progress in International Reading Literacy Study 2001 conducted by the The International Association for the Evaluation of Educational Achievement and comprises some 10,000 students in grade 3. Methods The effects of parents' education on reading achievement are estimated with structural equation modelling. Results The results reveal that the total effect of parents' education is substantial and that almost half of this effect is mediated through other variables, i.e. the number of books at home, early literacy activities, and emergent literacy abilities at the time for school start. The article thus identifies some of the mechanisms through which parents' education exert an influence on children's literacy development. Conclusions Cultural reproduction starts in the very early childhood, in informal settings where reading aloud is an important activity. The knowledge of written language that children have at the time for school‐start influences further reading acquisition. 相似文献

If the language is extended by new individual variables, in classical first order logic, then the deduction system obtained
is a conservative extension of the original one. This fails to be true for the logics with infinitary predicates. But it is
shown that restricting the commutativity of quantifiers and the equality axioms in the extended system and supposing the merry-go-round
property in the original system, the foregoing extension is already conservative. It is shown that these restrictions are
crucial for an extension to be conservative. The origin of the results is algebraic logic.

We define a multi-modal version of Computation Tree Logic (ctl) by extending the language with path quantifiers E
δ
and A
δ
where δ denotes one of finitely many dimensions, interpreted over Kripke structures with one total relation for each dimension. As
expected, the logic is axiomatised by taking a copy of a ctl axiomatisation for each dimension. Completeness is proved by employing the completeness result for ctl to obtain a model along each dimension in turn. We also show that the logic is decidable and that its satisfiability problem
is no harder than the corresponding problem for ctl. We then demonstrate how Normative Systems can be conceived as a natural interpretation of such a multi-dimensional ctl logic.

In recent years, some people have held that a radical relativist position is defensible in some philosophically interesting
cases, including future contingents, predicates of personal taste, evaluative predicates in general, epistemic modals, and
knowledge attributions. The position is frequently characterized as denying that utterance-truth is absolute. I argue that
this characterization is inappropriate, as it requires a metaphysical substantive contention with which moderate views as
such need not be committed. Before this, I also offer a more basic, admittedly less exciting alternative characterization
of the position, in terms of departing from the Kaplan–Lewis–Stalnaker two-dimensional framework. 相似文献

The present study examined the influence of two regulatory mode concerns—a locomotion concern with movement from state to state and an assessment concern with making comparisons—on choices between immediate and delayed (from 2 to 6 weeks) money rewards. Regulatory mode orientation was induced by means of a priming procedure. We predicted that the choices in the assessment condition would be less impulsive and more far‐sighted than those in the locomotion condition. After taking into account the effects of amount of early reward, length of delay and increase in delayed reward—all of which were in the direction of previous studies—this regulatory mode prediction was supported. Our findings suggest that it might be possible to induce more far‐sighted (or economically rational) inter‐temporal choices by means of instructions that induce an assessment orientation independent of stable inter‐individual differences in discount rate.

Recent research suggests that personality traits are associated with delinquency. T-tests were run to identify which traits and facets of the Five-Factor Model of Personality contributed to differentiate persistent juvenile delinquents (n = 48) from normative peers (n = 48). Results showed that two traits, namely Agreeableness and Neuroticism, and 12 facets differed significantly between the groups. Observed effect sizes varied from medium to large. 相似文献

This study examined the relationship between heart rate variability (HRV), as an index of individual differences in emotion
regulation, and perception of other-blame, as a mechanism of anger induction. The physiological responses were recorded while
subjects read a story from a computer screen. The story narrated a negative event in self-referred way -dismissal from a job
as the result of a colleague’s action- under conditions of intentionality versus non-intentionality. Cognitive and emotional
variables were assessed by questionnaire immediately after the physiological test. The resulting structural model supports
the conclusion that HRV exerts its regulatory influence directly on perception of other-blame rather than on emotion. In situations
of intentionality, individuals with higher HRV make less extreme evaluation of the offender’s blame, versus those with lower
HRV, thus leading to a reduction in anger reaction. These results suggest that HRV is a direct index of cognitive rather than
emotional regulation. 相似文献

Determinants of Flu Vaccination among Nurses: The Effects of Group Identification and Professional Responsibility 总被引:1,自引:0,他引:1
Juan M. Falomir-Pichastor Letizia Toscani Sophie Huyghues Despointes 《Psychologie appliquee》2009,58(1):42-58
Five hundred and thirty-one nurses completed a questionnaire assessing knowledge about the flu and flu vaccination, professional group identification, perception of the flu vaccination as a professional duty, previous year's vaccination status, intention to receive vaccination in the following year, and the extent to which motivation to accept vaccination is primarily for self-protection or for patient protection. Results showed that knowledge about the flu and flu vaccination constitutes a major reason for rejecting immunisation. Group identification also constitutes an independent predictor of vaccination. Furthermore, the effect of identification on willingness to receive the vaccination was partially mediated by perceived professional responsibility: the more nurses identified with their group, the more they perceived vaccination as a professional duty and, as a consequence, the more likely that they (a) had been vaccinated the previous year, (b) intended to be vaccinated in the following year, and (c) were motivated to be vaccinated for patient protection (but not for self-protection). 相似文献
