    近四十年来,由于农村人均可耕地面积的减少,城乡收入差距很大,为了提高生活质量,大量的农民涌入城市打工,但是许多孩子、老人甚至妇女却留在家里,成为“留守人员”,留守人员中的老人就称为留守老人。 养老一直是个老生常谈的话题,尤其是农村留守老人的养老问题,更是国家和社会关注的难点和热点。目前,养老产业正处于“三期叠加”的全面爆发前夕,加快推进养老服务业发展,是积极应对人口老龄化,满足持续增长的养老服务需求,也是全面实现“十三五”规划的一项紧迫任务。 本文结合作者自身工作环境和特点,以南平市顺昌县大历镇为例,在国内外已有的相关文献进行梳理的基础上,以问卷调查、个别访谈的方法,对顺昌县大历镇的留守老...Since China’s reform and opening-up to the outside world, the income gap of the urban and rural residents has become increasingly wider. Due to the reduction of cultivable land per capita in rural areas, farmers’ income from traditional cultivation doesn’t keep up with the economic development, thus more and more farmers choose to go to the cities and become migrant workers. This increases the fam...学位:公共管理硕士院系专业:公共事务学院_公共管理硕士学号:1392013115046

    共同应对气候变化已成为全球性的共识。《京都议定书》中给附件I国家和非附件I国家规定了“共同但有区别的减排责任”。但随着各国履行减排承诺的推进,不少问题接踵而至。发达国家担心减排行动导致碳泄漏及本国企业竞争力损失,以此为由,提出对来自发展中国家的碳密集型产品征收碳关税。无疑碳关税的实施将会对中国的经济和环境造成影响,该问题值得研究。 基于以上背景,本文首先综述了碳关税对经济和环境影响的理论分析和实证研究,以及碳关税的实证分析方法。然后构建碳关税经济环境影响的动态CGE模型,此模型是在CHINAGEM的基础上构建能源、碳排放和碳关税模块。本文利用WIOD数据库测算出十大高碳行业。由于WIOD数据...All countries and regions should corporate with each other to deal with global warming ,which has become a global consensus.

    Tässä opinnäytetyössä tutkittiin tankotanssijoiden urheiluvammoja kvantitatiivisin menetelmin. Tutkimustulosten perusteella pystytään jakamaan uutta tietoa lajin urheiluvammoista tankotanssin parissa toimiville henkilöille, kuten valmentajille, harrastajille, kilpailijoille ja lajista kiinnostuneille. Tutkimuksessa selvitettiin, kuinka monelle tankotanssijalle on tullut urheiluvammoja. Vammoista selvitettiin sen kohdealue, laatu ja koetun haitan kesto. Lisäksi selvitettiin iän, sukupuolen, kokemusvuosien ja viikoittaisen harjoittelutuntimäärän yhteydet vammautumisiin. Kysely jaettiin keväällä 2018 ympäri Suomea tankotanssikouluihin ja se oli menetelmältään kvantitatiivinen. Vastauksia tuli yhteensä 262 kappaletta. Kerätty aineisto syötettiin ja analysoitiin MS Excel- ja IBM SPSS Statistics -ohjelmistoilla. Tuloksista kävi ilmi, että yleisimmät urheiluvammat tankotanssissa kohdistuvat yläraajaan olkapään alueelle. Vammat koettiin lihasperäisiksi rasitusvammoiksi ja niiden aiheuttama haitta oli useimmiten 1 – 4 viikkoa. Viikkoharjoittelutuntimäärällä oli selkeästi yhteyttä vammojen esiintyvyyteen (p=0,036), mutta sen riippuvuus oli heikko (C=0,032). Kokemusvuosilla oli selkeästi yhteyttä vammojen esiintyvyyteen (p=0,0065). Vastauksista kävi ilmi, ettei ikä ollut tilastollisesti merkitsevä tekijä vammojen esiintyvyydessä (p=0,095).The aim of this bachelor’s thesis was to carry out a research of sports injuries among pole dancers with quantitative methods. The material was collected with a structured electric questionnaire. The purpose was to innovate new knowledge about sports injuries among pole dancers. The information can be used by coaches, amateurs, professionals, and others who are interested in the sport. This study’s objective was to clarify how many pole dancers has had a sports injury. The other examined matters were the target areas of sports injuries, their quality, and how long was the duration of one’s experienced drawback after injury. Furthermore, the researchers were interested in the possible connection of age, gender, years of experience, and weekly practice hours to sports injuries incidence. The questionnaire was shared to Finnish pole dancing schools in spring 2018 and a total of 262 replies were received. The survey was quantitative, and the gathered material was analyzed with MS Excel, and IBM SPSS Statistics software. According to the results, it appears that the most general sports injuries in pole dancing are directed to the upper limb, more precisely to the shoulder area. The injuries were experienced as mostly repetitive strain injuries. The usual experienced drawback period was 1 to 4 weeks. There was a clear connection with weekly practice hours and the incidence of injuries (p=0,036), but they only had a weak dependence (C=0,032). The years of experience had a clear connection to the incidence of injuries (p=0,0065). Age was not a statistical significant factor in incidence of sports injuries (p=0,095)

    在某些刑事案件尤其是伤害类的案件中,被告人对被害人实施了危险程度较低的行为(既可以是言语刺激行为也可以是肢体行为),如果该行为作用于非特殊体质人通常不会产生严重的后果,但由于被害人具有某种特殊体质,被告人的行为与被害人的特殊体质相结合发生了被害人受伤或死亡的结果。在该种情况下,问题接踵而至:因果关系认定方面,究竟如何判断被告人的这种危险程度较低的行为与严重后果之间的因果关系,刑法因果关系的成立与否是否受被害人特殊体质的影响,所产生的被害人受伤或死亡的严重后果该不该归咎于被告人的行为?被告人的主观恶性的甄别方面,该如何区分该类案件是出于行为人何种罪过,是故意、过失还是无罪过?如果认定了被告人的行...In some criminal cases especially the injury cases, the defendant carried out less dangerous behavior on the victim (both verbal stimulation behavior and physical act can be ), if the act applies to non special constitution of people usually do not have serious consequences, but because the victim has some kinds of special physical constitution, the combination of special constitution and the defe...学位:法律硕士院系专业:法学院_法律硕士学号:X201312011

    厌氧条件在不同Fe( II) 浓度测定方法中必要性的比较研究

    Get PDF
    厌氧是目前Fe(II)测定方法中常选择的处理方式,但是不可避免会给实验操作带来不便。为了方便、准确地测定铁还原体系中的Fe(II)浓度,对比研究了厌氧条件对草酸—草酸铵和盐酸两种典型浸提方法测定Fe(II)浓度的影响。结果表明:对于草酸—草酸铵浸提法,厌氧条件是必须的,以防止提取液中的Fe(II)被氧化,而且样品浸提1 h 便可用于Fe(II)的测定;然而对于盐酸浸提法,厌氧条件却并不是必须的,对Fe(II)浓度测定基本不产生影响。因此,为简化实验操作或在没有厌氧条件的情况,可利用盐酸浸提法测定铁还原体系中Fe(II)浓度
