国债规模风险评估的广义差分法模型

为了缓解通货紧缩的压力,扭转经济持续下滑的局面,1998年我国开始实行积极的财政政策,从1998年到2001年,我国政府共发行了5100亿长期建设国债.连续多年实行积极的财政政策,一方面起到了促进经济的景气回升的作用,拉动了民间投资,保证了一批重要的基础设施项目的建设,推动了企业技术改造和产业升级;另一方面,国债增加所带来的利息负担也使得财政赤字增加得比较快,国债余额累积数不断增大,赤字率和国债负担率都比1998年以前有了明显的大幅度地上升,使得财政风险和国债风险越来越成为人们关注财政政策走向的焦点.     

离战争最近的海航尖刀

征服一个又一个高难课目 战法是对抗之法,对抗是战法训练的灵魂.红蓝对抗是最有效的对抗方式. 2007年6月,现任东海舰队航空兵部队参谋长、时任师长魏华彬,在该大队组建了海军航空兵第一支三代机蓝军分队. 蓝军分队成员都是从海空雄鹰团挑选出的训练尖子,但他们面对蓝军训练大纲却表现得惊人的一致:难!太难了!笔者随手翻开蓝军训练大纲,发现仅单机、编队进攻防御战术机动等基础训练课目,就设置了数十套动作,并且所有动作几乎都在身体承受极限条件下进行.     

有利砂体识别与解释

天然气的产量与砂岩的厚度,孔隙度,连通性,砂泥比等有密切的关系。为了解决砂体在空间以什么形态出现,其方向如何,纵向上如何变化,连通形式如何等问题,在前人研究的基础上,对篷来镇组某工区的砂体进行了精细识别和解释。在地震剖面上,砂体的响应一般表现为强振幅,低频率。孔隙性好,含气丰度高的砂体往往表现为速度低和极性反转的特点。但发现该工区的砂体在地震剖面上表现形式多变,甚至出现了合成地震记录与井旁地震记录严重不吻合的现象,故砂体识别工作不能遵循统一模式。因此,采用了多井约束,多层标定,分层解释来识别有利砂体。     

Ergonomic and individual risk evaluation

The ergonomic risks constitute a vital aspect of study and prevention for the worker's health, especially for people with different capacities. Very job has and implies certain type of risk for the worker's health, depending on the conditions it is done with the use of tools or without them. Aplicated techniques: posturogram, baropodometry, Schober test, biocinemátic chain test, Fukuda test, propioceptiva plataform in personnel with special capabilities.     

Irregular working times and metabolic disorders among truck drivers: a review

A number of studies to better understand the complex physiological mechanism involved in regulating body weight have been conducted. More specifically, the hormones related to appetite, leptin and ghrelin, and their association to obesity have been a focus of investigation. Circadian patterns of these hormones are a new target of research. The behaviour of these hormones in individuals subject to atypical working times such as shiftwork remains unclear. Shiftwork is characterized by changes in biological rhythms and cumulative circadian phase changes, being associated with high rates of obesity and metabolic syndrome. Truck drivers, who work irregular shifts, frequently present a high prevalence of obesity, which might be associated with work-related factors and/or lifestyle. In this context, the aim of this paper was to discuss the relationship of body mass index, appetite-related hormones and sleep characteristics in truck drivers who work irregular shifts compared with day workers.     

在夹缝中沉沦--论晚清海军国产舰船地位的边缘化

晚清政府在19世纪60年代中期设厂造船,开始了近代海军的建设历程。国产舰船在晚清海军发展的过程中也曾经占有主要地位,为海防建设作出了巨大贡献。但由于自身质量问题以及来自外部的冲击,官办造船厂存在的先天弊端以及统治者海洋意识的淡薄等原因,国产舰船在晚清海军舰船装备建设中的地位日益被边缘化,最终导致近代海军建设的失败,给近代中国带来巨大的危害。     

Why females live longer than males: control of longevity by sex hormones

Females live longer than males in many species, including humans. We have traced a possible explanation for this phenomenon to the beneficial action of estrogens, which bind to estrogen receptors and increase the expression of longevity-associated genes, including those encoding the antioxidant enzymes superoxide dismutase and glutathione peroxidase. As a result, mitochondria from females produce fewer reactive oxygen species than those from males. Administering estrogens has serious drawbacks, however--they are feminizing (and thus cannot be administered to males) and may increase the incidence of serious diseases such as uterine cancer in postmenopausal women. Phytoestrogens, which are present in soy or wine, may have some of the favorable effects of estrogens without their undesirable effects. Study of gender differences in longevity may help us to understand the basic processes of aging and to devise practical strategies to increase the longevity of both females and males.

Rethinking a universal framework in the psychiatric symptom-disorder relationship

Research on disparities in health and services should include a critical examination of how social, cultural, and contextual factors affect the connection between symptoms and psychiatric disorders. Systematic differences in this connection by these factors will mean that clinicians using a universalist approach to disorders may make more diagnostic errors for certain patients (e.g., ethnic minorities, the poor). Based on the literature on normative clinical decision-making, this study tests for whether the effect of specific psychiatric disorders on key symptoms is the same for certain groups of the population. The data come from the National Comorbidity Survey. Conditional probabilities of disorders and symptoms, the elements feeding into clinical decision-making, are calculated and tested for equivalence across various racial/ethnic, educational, income, and gender groups. We find some significant differences in the relation of key symptoms to disorders across groups. These findings should encourage testing relativistic frameworks in diagnostic nosology as a step to improve clinical decision-making and reduce diagnostic and treatment disparities in mental health services.
