通用桥式起重机主梁自重对拱度的影响及修正

通用桥式起重机主梁上拱度是起重机的重要技术指标,因此生产检测中所测的拱度值必须保证是准确可靠的。而在进行起重机桥架结构时,由于各种条件的限制,支架位置常常处于0.8倍跨度处,此时主梁自重对主梁拱度产生的影响值会有偏差,造成测得的主梁上拱度值是不准确的,因此需要对该值进行修正。通过生产实践总结和理论计算相结合,可准确得出支架位置在0.8倍跨度处主梁自重对主梁上拱度的影响修正值,此时测得的拱度值再减去修正值后就是准确的拱度值。     

Business-model (intent)-based accounting

We discuss how basing financial reporting on an entity's business model is, in effect, basing financial reporting on management's intent with respect to the use, transfer or other disposition of an asset or liability. We provide several examples of existing International Financial Reporting Standards and US Generally Accepted Accounting Principles that permit or require intent-based accounting. We describe the meaning and consequences of basing the accounting for financial assets on management's intentions for realising value from those assets. We analyse the positive and negative features of intent-based accounting in the context of the Financial Accounting Standards Board's and International Accounting Standards Board's conceptual frameworks, specifically, the qualitative characteristics relevance and comparability and the objective of financial reporting, and apply that analysis to existing and proposed guidance for measuring financial assets. We also discuss evidence from academic research on the measurement of financial assets.

Adolescents' body‐tanning behaviours: influences of gender,body mass index,sociocultural attitudes towards appearance and body satisfaction

The goal of this study was to identify and examine the various factors affecting adolescents' body‐tanning behaviours. Gender, body mass index (BMI), sociocultural attitudes towards appearance (SATA) and body satisfaction were examined in order to determine how these variables influence both outdoor sun‐tanning and indoor tanning‐bed use. Self‐administered survey data were collected from 155 adolescent boys and 202 adolescent girls with an average age of 14.3. Multivariate analysis of variance and multiple regression methods were used to analyse the data. Adolescent girls tended to engage in both outdoor and indoor tanning. Overall, adolescents' SATA significantly affected their body‐tanning behaviours. However, BMI and body satisfaction revealed a significant effect only on indoor tanning behaviour. Implications for the design of interventions and overall health promotion towards adolescents are discussed with suggestions for future research.

利用遥控心率仪器对女大学生减肥的实验研究

肥胖是常见病,对人类的危害很大。肥胖的治疗应该是综合治疗,运动减肥已经引起人们足够的重视,但实际上科学的减肥方式并没有为大多数人所认识。本文利用遥控心率仪器进行实验,通过选择不同的运动方法对减肥者进行有效的心率控制。运用问卷调查和实验的方法,使受试者达到较好的减肥效果。利用遥控心率进行减肥是科学的、合理的,适宜的运动心率是减肥的较好手段。

论城市土地定级权重确定方法之——综合集成赋权法

影响土地质量的因素很多，但对土地质量的影响程度并不相同，只有通过因素权重的科学确定才能正确揭示土地质量差异。如何确定城市土地定级权重系数，是土地资源综合评价中的核心问题。本文在分析传统主观、客观土地定级因素权重确定方法和土地定级因素与土地质量之间的联系的基础之上，提出同时体现主观和客观信息的综合集成赋权法，介绍了应用综合集成赋权法确定土地定级因素权重的具体方法，对综合集成赋权法运用于土地定级因素权重确定的可行性进行了探讨。     

从现代产权制度着眼 深入推进国有林权改革

在论述国有林区建立现代产权制度重要意义的基础上,对伊春的林权制度改革目标和内容进行了阐述。认为伊春林区实行的以职工家庭对国有林地进行承包经营为主要内容的产权形式,是国有林区的一种优越的经济制度选择;其核心目标是在国有森林资源领域真正建立起归属清晰、责权明确、保护严格、流转顺畅的现代产权制度。
