单是一种气度,孤是一种绝望。人生可以单,却不能孤。一周末的晚上去看电影,偶遇几位同事。他们见我独自前来,都露出惊讶的表情:"你一个人?"我左手拿着爆米花,右手拿着可乐,手指里还夹着电影票,忙不迭点头:"对呀,这家影院就在楼下,我经常一个人来,很方便。"他们倒吸一口凉气。虽然没再说什么,可看向我的眼神却 相似文献

Like many river basins in China, water resources in the Fudong Pai River are almost fully allocated. This paper seeks to assess and evaluate water resource problems using water evaluation and planning (WEAP) model via its application to Hengshui Basin of Fudong Pai River. This model allows the simulation and analysis of various water allocation scenarios and, above all, scenarios of users' behavior. Water demand management is one of the options discussed in detail. Simulations are proposed for diverse climatic situations from dry years to normal years and results are discussed. Within the limits of data availability, it appears that most water users are not able to meet all their requirements from the river, and that even the ecological reserve will not be fully met during certain years. But the adoption of water demand management procedures offers opportunities for remedying this situation during normal hydrological years. However, it appears that demand management alone will not suffice during dry years. Nevertheless, the ease of use of the model and its user-friendly interfaces make it particularly useful for discussions and dialogue on water resources management among stakeholders. 相似文献

Smith and Nelson (1985), cited in Taylor (2003), distinguish between intelligibility, comprehensibility, and interpretability. For them intelligibility has to do with word or utterance recognition, comprehensibility with word or utterance meaning, and interpretability with illocutionary force. 相似文献

Immunomodulatory function of orally administered thymosin α1 总被引:1,自引:0,他引:1

INTRODUCTION The thymus is a vital immune organ and plays a very important role in the development and mainte- nance of the lymph system. The extract of animal thymus has been used in clinical practice as an ad- junct treatment in patients with carcinoma, viral in- fection and immunodeficiency, but the extract con- taining miscellaneous animal proteins may easily lead to allergy in patients. Thymosin α1 (Tα1) is the most potent ingredient in thymosin and the biological ac- tivity of pur… 相似文献

Definitions of bullying: a comparison of terms used,and age and gender differences,in a fourteen-country international comparison 总被引:2,自引:0,他引:2

The study of school bullying has recently assumed an international dimension, but is faced with difficulties in finding terms in different languages to correspond to the English word bullying. To investigate the meanings given to various terms, a set of 25 stick-figure cartoons was devised, covering a range of social situations between peers. These cartoons were shown to samples of 8- and 14-year-old pupils (N = 1,245; n = 604 at 8 years, n = 641 at 14 years) in schools in 14 different countries, who judged whether various native terms cognate to bullying, applied to them. Terms from 10 Indo-European languages and three Asian languages were sampled. Multidimensional scaling showed that 8-year-olds primarily discriminated nonaggressive and aggressive cartoon situations; however, 14-year-olds discriminated fighting from physical bullying, and also discriminated verbal bullying and social exclusion. Gender differences were less appreciable than age differences. Based on the 14-year-old data, profiles of 67 words were then constructed across the five major cartoon clusters. The main types of terms used fell into six groups: bullying (of all kinds), verbal plus physical bullying, solely verbal bullying, social exclusion, solely physical aggression, and mainly physical aggression. The findings are discussed in relation to developmental trends in how children understand bullying, the inferences that can be made from cross-national studies, and the design of such studies. 相似文献

INTRODUCTION Chronic hepatitis B virus (HBV) infection is aserious clinical problem because of its wide distribu-tion and possible adverse consequences, such as he-patic decompensation, cirrhosis and/or primary livercancer (PLC). The natural course of chronic HBVinfection is characterized by a series of hepatitic flaresor exacerbations and remissions (Ganem and Prince,2004). The severity, extent, duration and frequency ofhepatic histopathological changes in hepatitic flaresare d… 相似文献

Two experiments were conducted to examine whether and how 4- and 5-year-olds learn to distinguish determinate from indeterminate evidence. Children were asked to decide whether various patterns of evidence were sufficient to reach unambiguous conclusions. This study replicated the finding that young children tend to use a strategy that, although generally successful, fails on evidence patterns in which a single positive instance co-occurs with an unexplored source of evidence. Experiment 1 demonstrated that this positive-capture strategy is deeply entrenched, even in a meaningful, pragmatic context. With a microgenetic design, Experiment 2 revealed that young children are capable of replacing the positive-capture strategy with a correct strategy when they are exposed to various analogous tasks in several training sessions. 相似文献

Diffusion tensor imaging of the brain in patients with Alzheimer's disease and cerebrovascular lesions 总被引:1,自引:0,他引:1
Background: Recent autopsy study showed a high incidence ofcerebrovascular lesions in Alzheimer's disease (AD). To assess the impact of cerebrovascular pathology in AD, we used diffusion tensor imaging (DTI) to study AD patients with and without cerebrovascular lesions. Materials and Methods: Conventional and DTI scans were obtained from 10 patients with probable AD, 10 AD/V patients (probable AD with cerebrovascular lesions) and ten normal controls. Mean diffusivity (D) and fractional anisotropy (FA) values of some structures involved with AD pathology were measured. Results: D value was higher in AD patients than in controls in hippocampus and the cingulate gyrus. In AD/V patients, increased D value was found in the same structures and also in the thalamus and basal ganglia compared to controls. There was a significant difference of D value between AD and AD/V patients. FA value reduced in the white matter of left inferior temporal gyrus and in the bilateral middle cingulate gyrus in patients with AD/V compared with controls. The MMSE (mini-mental state examination) score significantly correlated with FA value in the right hippocampus (r=0.639, P〈0.019), in the right anterior cingulate gyrus (r=0.587, P〈0.035) and in left parahippocampal gyrus (r=0.559, P〈0.047). Conclusion: Cerebrovascular pathology had stronger impact on the D value than the AD pathology alone did. Elevated D value in thalamic and basal ganglia may contribute to cognitive decline in AD/V patients. Reduced FA values in AD/V patients may indicate that cerebrovascular pathology induced more severe white matter damage than the AD pathology alone did. 相似文献
