对高校运动训练计划可变性与稳定性的研究

在制定训练计划过程中,只有正确把握好训练计划中可变性与稳定性的关系,才能使训练工作更有针对性。这是做好教练工作的关键问题,也是经验训练走向科学训练的第一步。     

土地资源管理专业实践教学体系改革研究

实践教学在高校本科人才培养过程中具有重要作用。本文在分析土地资源管理专业定位和人才培养目标的基础上,尝试构建以课间实习、小学期综合实习、土地软件综合实习、毕业实习为主要环节的工科型土地资源管理实践教学体系。     

民国时期中小学训育方法的探寻

合理的、有效的训育实施方法是实现中小学训育目标,获得良好的训育效果的必要条件。民国时期,教育界围绕着中小学训育实施的方法进行了理论与实践上的深入探索,逐渐总结出的训育实施方法如:注重隐性课程的耳濡目染、强调学生自治能力的培养与发展、依重实践活动来磨砺意志等,都探及了中小学校道德教育的核心。这些总结出来的训育方法切实可行,取得了令人啧啧称叹的成绩,但也留下了不小的遗憾。当时中小学校学风不纯、机会不均、社会不安、施政者"执法严绳"恐吓学生,皆与训育实施原则、理念与方法背道而驰,导致了民国时期训育的失败。即使如此,当时对训育实施方法的探索成果仍给中小学校道德教育留下了宝贵的精神财富。     

Portfolio Selection Model with Derivative Securities

Traditional portfolio theory assumes that the return rate of portfolio follows normality ,However,this assumption is not true when derivative assets are incorporated,In this paper a portfolio selection model is devel-oped based on utility function which can captue asymmetries in random variable distributions.Other realistic conditions are also considered ,such as liabilities and integer decision variables,Since the resulting model is a complex mixed-integer nonlinear programming problem ,simulated annealing algorithm is applied for its solution.A numerical example is given and sensitivity analysis is conducted for the model.     

二十世纪日本汉学界之荀子名学研究综述

在先秦时期,除了名家和墨家之外,在名学研究方面,其成就最大的当属荀子。荀子对于先秦名学之贡献主要是进一步批判和发展名家和墨辩之名学,使儒家之名学更加严谨。然而,历来有关荀子之研究多着眼于其心、性、天、礼等之探讨,而疏于抉发其名学之义蕴。直到近年来,由于大陆学界积极挖掘中国古代之逻辑思想,以免西方逻辑专美于前,于是有关中国逻辑史或逻辑思想之论着,如雨后春笋般出现。此等有关中国逻辑论者之研究对象主要为先秦时期讨论名实辩说之篇章,尤其是公孙龙、墨辩和荀子名学之研究。此外,由于一些国外学者之参与,使得中国古代逻辑之研究,尤其是关于荀子名学之研究,如今已成一较为普遍之现象。有关荀子之研究,日本汉学界已作出极为可喜之成绩。唯历来有关荀子之研究,日本汉学界多着重其心、性、天、礼或政治、伦理学说之阐述,而较疏于其名学之研究。然而,就目前已发表之论着而言,无论是在厘清荀子之哲学立场或对于名学之分析等,亦颇有其独到之处,值得吾人借镜。     

试述周恩来旅欧期间的历史贡献

1920年11月至1924年7月,周恩来赴法勤工俭学,探求革命真理.旅欧期间,周恩来为中国人民的解放事业作了巨大贡献.他创建的旅欧党团组织成为中国共产党8个发起组织之一;他领导旅欧学生和华工开展的反帝反封建斗争,开创了知识分子和无产阶级相结合道路的先河;他协助筹建国民党旅欧支部,建立了广泛的统一战线;他培养和凝聚优秀人才,成为了中国共产党第一代和第二代领导的重要力量.     

Dynamic Transition Patterns in Acculturation Among Hispanic Adolescents

Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, M_age (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed.     

基于多频互控分析的记发器信令生成器的工程设计实现

1号信令是电话接续的重要信令,作为1号信令重要组成部分的记发器信令的生成与检测一般都是由专用芯片实现。由于硬件接口和功能固定,在实际使用中往往受到很大限制,因此用通用芯片来实现这一功能可以大大增加灵活性,兼容性。但在软硬件设计之前,准确分析记发器信令的信号波形特性十分重要,往往会决定最终的设计性能指标。首先分析记发器信令的具体物理特性,其具体实验数据取自于满足1号信令协议标准的相关设备,然后分析记发器信号的多频互控流程,包括编码序号和频率成分的对应关系、信号的具体分类、信号的发送流程等,这对于建立从协议层到物理层的相关机制都是十分有意义的。最后给出工程设计的基本思路,包括从ARM+DSP的架构设计、逻辑层次设计、相互之间的接口关系、配合机制等。     

A coach’s political use of video-based feedback: a case study in elite-level academy soccer

This paper examines the video-based pedagogical practices of Terry (pseudonym), a head coach of a professional junior academy squad. Data were collected through 6 in-depth, semi-structured interviews and 10 field observations of Terry’s video-based coaching in situ. Three embracing categories were generated from the data. These demonstrated that Terry’s video-based coaching was far from apolitical. Rather, Terry strategically used performance analysis technologies to help fulfil various objectives and outcomes that he understood to be expected of him within the club environment. Kelchtermans’ micropolitical perspective, Callero’s work addressing role and Groom et al.’s grounded theory were primarily utilised to make sense of Terry’s perceptions and actions. The findings point to the value of developing contextually grounded understandings of coaches’ uses of video-based performance analysis technology. Doing so could better prepare coaches for this aspect of their coaching practice.
