An Empirical Study on the Term Structure of Treasury Bond Yield to Forecast Inflation
随着信用货币的诞生,通货膨胀进入了人们的经济生活。各国政府日益认识到控制通货膨胀的重要性。合理有效地控制通货膨胀需要对通货膨胀未来路径进行预测。预测通货膨胀未来路径的方法有很多,其中一种是从现有金融资产交易信息中去挖掘市场对通货膨胀的信息。 本文基于这一背景,参照已有的相关文献,对中国银行间市场国债交易数据进行挖掘,考察国债收益率期限结构中是否包含有对通货膨胀未来路径的预测信息。首先,从基本的利率期限结构静态拟合模型中进行筛选,挑选出适合中国国债交易数据的拟合模型,这一部分是基于本文选取的样本段数据2003年10月至2013年7月的国债交易月末交易日收盘数据,根据利率期限结构的特征对拟合模型...With the birth of the credit currency, inflation has entered the people's economic life.

Studies on Multiwavelength Radiation of X-ray Binaries and Magnetohydrodynamic Turbulence
本学位论文的研究主要致力于两个科学目标,其一是理解~X~射线双星多波段辐射的起源及特性;其二是基于同步辐射偏振色散的统计技术,使用 数值模拟方法研究磁流体力学(MHD)湍流的性质。基于强子或轻子主导辐射的假设,论文建立~X~射线双星主要活动区的辐射模型, 如喷流底、中部区、喷流终端与周围星际介质(ISM)作用区、吸积盘、磁层等辐射区,研究多波段光子谱及高能中微子的辐射。 MHD\湍流是天体内部物质运动的必然结果,研究它有重要意义,因为对它的研究不仅可以促进人们理解~X~射线双星的高能过程,而且它对恒星的形成、宇宙射线的传播及加速、热传导、磁重联等都有重要影响。 基于强子辐射主导的考...The research of this dissertation is mainly devoted to two scientific goals.

近25 a 银川市城市化进程中热力景观格局演变分析
Abstract: Based on the Landsat images and statistical data,in this paper the urbanization process and thermal landscape dynamics of Yinchuan City were analyzed. The objectives of this study were as follows: ① To analyze the spatial and dynamic characteristics of urban thermal landscapes based on the landscape pattern index; ② To assess the influence of the urbanization process on the thermal landscapes; ③ To understand the relationship between the land use pattern and the land surface temperature ( LST) based on the distribution index. The results showed that there was a significant heat-island effect in Yinchuan City,and the high temperature area was consistent with the built-up area and the unused land. LST declined from the downtown to the suburbs,and an obvious difference of the dynamic characters of the thermal landscapes could be identified at the different stages of urbanization. LST for various land use had obvious discrepancies,the mean LST for the land use types was in a descending order of unused land,construction land,green land and water body. Different land use types had different thermal distribution at different stages of urbanization. The land use pattern influenced the urban thermal environment,especially the spatial distribution of green land and unused land affected LST more significantly
Kartoitus tankotanssijoiden urheiluvammoista : kvantitatiivinen kyselytutkimus
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)
