高校学报多功能特征与出版体制改革的政策建议——基于农业多功能性理论的启示

随着出版体制改革的不断深入,高校学报办刊体制改革成为热门话题。根据农业多功能理论的启示,对高校学报多功能特征进行研究。研究结果表明,高校学报不仅具有一般学术期刊的传播功能,还具有高校学术成果的展示功能、高校学术研究的引领功能、高校学术规范的示范功能、高校学术诚信体系的建设功能、高校学术新人的培植功能、高校学术文化的传承功能。根据这些功能剖析,提出高校学报不仅有合理的生存空间,而且有巨大的发展潜力,市场化的办刊模式不适合高校学报。学报工作者要树立信心,调整角色定位,提高学术能力。

基于农业多功能性的江苏美丽乡村建设研究

美丽乡村建设是2013年“中央1号”文件正式提出农村工作的重要举措。习近平总书记在2013年底召开的中央农村工作会议上强调,建设美丽中国,必须建设好“美丽乡村”。基于农业多功能性、可持续发展等理论,系统阐述了美丽乡村的“四重功能”,即“生态宜居、生产高效、生活美好、人文和谐”。在此基础上,通过实证调查研究与专家咨询,指出目前江苏美丽乡村建设中存在的如“新理念”缺乏、“新动能”不足及“新机制”有待提高等较为共性的问题,并就如何从高质量可持续建好美丽乡村提出了三个“新”的意见和建议。即“新理念”,建设美丽乡村要充分挖掘、拓展和彰显美丽乡村的多重功能,努力提升美丽乡村的多元价值;“新动能”,要进一步聚焦主导产业,加大对新业态、新主体和新农民的培育、培植和培训,为农业产业高质量发展注入新动能;“新机制”,要创新村级合作经济联农带农发展的机制,夯实村级集体经济基础,为可持续建设和发展美丽乡村注入活力。

多功能脑电生物反馈系统对ADHD及感觉统合失调的诊断和治疗研究

目的:阐明多功能脑电生物反馈系统对注意力缺陷伴多动症(attention deficit hyperactivity disorder,ADHD)儿童的干预治疗效果及对感觉统合失调的诊断和治疗意义。方法:选取ADHD患儿和非ADHD儿童各60例分别作为研究组和对照组。记录两组某一时段脑电波,观察θ波/β波比值或者α波/β波比值,用脑电生物反馈系统对ADHD及感觉统合失调儿童进行诊断及治疗,通过对受试者进行反复的声音和视觉刺激,观察认知变量情况,最终得到综合反应控制商数和综合注意力商数,运用IVA-CPT评估系统进行评估以了解治疗效果。结果:研究组α波波幅显著低于对照组,θ波波幅显著高于对照组,β波频率显著低于对照组(P<0.05)。研究组脑电相对功率θ/α、θ/β显著高于对照组,β波、SMR波脑电相对功率显著低于对照组,θ波相对功率显著高于对照组(P<0.05)。研究组6个IVA-CPT综合尺度商数显著低于对照组(P<0.05)。相关性分析:脑电相对功率、α波幅与听觉注意力商数、综合注意商数呈正相关,θ波频率、波幅与听觉注意力商数显著负相关,θ/α比值与综合注意商数、听觉注意力商数显著负相关,θ/β比值与综合反应控制商数、综合注意商数显著负相关(P<0.05)。经过治疗后ADHD患儿脑电功率指标θ%、θ/β比值出现显著下降,各商数水平均显著提高(P<0.05)。结论:多功能脑电生物反馈系统可作为诊断ADHD及感觉统合失调患儿的检查方法,且该方法可作为ADHD及感觉统合失调引起学习困难的主要治疗手段。

An estimation approach for dividable multiattribute utility of housing via questionnaires of consumers’ ordinal multicriteria preferences

Compared with ordinary commercial products, housing has many special characteristics including the multi-function characteristic. How to evaluate the multi-functional nature of housing is very useful in both theory and in application, yet it is often ignored in China. This paper introduces an approach to estimate the multicriteria function of housing using multiattribute utility theory (MAUT) based on consumers’ ordinal multicriteria preferences as determined via questionnaires. When compared with the classic framework in which MAUT is applied, this approach needs less prior information and subjective comparisons and thus can allay many of the operational difficulties involved in assessment. Some potential applications to the China housing market are also discussed.

Fog Detection over China's Adjacent Sea Area by using the MTSAT Geostationary Satellite Data

A fog threshold method for the detection of sea fog from Multi-function Transport Satellite (MTSAT1R) infrared (IR) channel data is presented.This method uses principle component analysis (PCA),texture analysis,and threshold detection to extract sea fog information.A heavy sea fog episode that occurred over China's adjacent sea area during 7 8 April 2008 was detected,indicating that the fog threshold method can effectively detect sea fog areas nearly 24 hours a day.MTSAT-1R data from March 2006,June 2007,and April 2008 were processed using the fog threshold method,and sea fog coverage information was compared with the meteorological observation report data from ships.The hit rate,miss rate,and false alarm rate of sea fog detection were 66.1%,27.3%,and 33.9%,respectively.The results show that the fog threshold method can detect the formation,evolution,and dissipation of sea fog events over period of time and that the method has superior temporal and spatial resolution relative to conventional ship observations.In addition,through MTSAT-1R data processing and a statistical analysis of sea fog coverage information for the period from 2006 to 2009,the monthly mean sea fog day frequency,spatial distribution and seasonal variation characteristics of sea fog over China's adjacent sea area were obtained.

Fast image matching algorithm based on affine invariants

Feature-based image matching algorithms play an indispensable role in automatic target recognition （ATR）. In this work, a fast image matching algorithm （FIMA） is proposed which utilizes the geometry feature of extended centroid （EC） to build affine invariants. Based on at-fine invariants of the length ratio of two parallel line segments, FIMA overcomes the invalidation problem of the state-of-the-art algorithms based on affine geometry features, and increases the feature diversity of different targets, thus reducing misjudgment rate during recognizing targets. However, it is found that FIMA suffers from the parallelogram contour problem and the coincidence invalidation. An advanced FIMA is designed to cope with these problems. Experiments prove that the proposed algorithms have better robustness for Gaussian noise, gray-scale change, contrast change, illumination and small three-dimensional rotation. Compared with the latest fast image matching algorithms based on geometry features, FIMA reaches the speedup of approximate 1.75 times. Thus, FIMA would be more suitable for actual ATR applications.

Linear recurring sequences and subfield subcodes of cyclic codes

Linear recurring sequences over finite fields play an important role in coding theory and cryptography. It is known that subfield subcodes of linear codes yield some good codes. In this paper, we study linear recurring sequences and subfield subcodes. Let Mqm(f(x)) denote the set of all linear recurring sequences over Fqm with characteristic polynomial f(x) over Fqm . Denote the restriction of Mqm(f(x)) to sequences over Fq and the set after applying trace function to each sequence in Mqm(f(x)) by Mqm(f(x)) | Fq and Tr( Mqm(f(x))), respectively. It is shown that these two sets are both complete sets of linear recurring sequences over Fq with some characteristic polynomials over Fq. In this paper, we firstly determine the characteristic polynomials for these two sets. Then, using these results, we determine the generator polynomials of subfield subcodes and trace codes of cyclic codes over Fqm .
