论古典诗法著作的编著内容

古代诗歌写作的具体法则和技巧主要集中保存在历代诗法著作中,但这批史料却长期存在于诗话群体中,沦落成了“边缘史料”。而实际上诗法著作的编著内容相对于诗话是具有自身特点的,它们主要以总结技巧为主,注重的是可操作性。将诗法注入神秘性,是早期诗法写作与传授的突出现象。诗法著作中也会有小部分规律的总结与理论的探索。     

日本《低碳投资促进法》述评

日本参议院于5月18日通过了《低碳投资促进法》,该法是日本建设低碳社会的最新立法,规定了对从事适合能源环境的制品开发与制造的特定事业者提供筹资支持,需求开拓支援法人承保租赁合同等措施,对我国的相关立法有一定的借鉴意义。     

专职守护押运人员防卫权研究

专职守护、押运人员执行守护、押运任务中使用枪支的行为,是依法执行职务的行为,属正当防卫的范畴;但与刑法规定的正当防卫相比,在防卫主体、手段、起因、限度、保护权益、主体义务等方面,又具有某些特殊性。     

兼具冬春性小麦农鉴1育成及应用

新品种农鉴1既能作冬性小麦抢墒早播,也可作春性小麦晚茬迟播,此种特异性状在理论上和生产上都有重要意义,国内外文献尚未见报导。本文提出有关数据资料阐述农鉴1替代冬性及春性品种的应用效果,并对农鉴1一系列综合优良性状及其社会效益、经济效益作了较详尽报导。     

谨慎性原则与实质重于形式原则的协调运用——新企业会计准则中存货期末计价视角

随着经济的发展,经济活动日益复杂,经济环境中的不确定性事件越来越多,同时复杂的经济活动也致使经济现象的表现形式日趋多样化.以投资者为主体的会计信息使用者一方面重视与不确定性相关的风险信息的提示,另一方面也迫切要求会计信息能反映企业的经济实质.因而,谨慎性原则与实质重于形式原则的运用成为必然.然而,会计界对两个原则在实务中的具体运用产生了不同的理解.在此,笔者拟以新会计准则中期末存货计价为切入点,通过构造案例,阐述谨慎性原则与实质重于形式原则的协调运用.

Φp-optimal second order designs for symmetric regions

Designs for quadratic regression on a cube, on a cube with truncated vertices and on a ball are studied in terms of a family of criteria, introduced by Kiefer (1974, 1975), that includes A-, D- and E-optimality. Both theoretical and numerical results on structure and performance are presented. In particular, D- and E-optimal designs are described and a procedure of construction of nearly robust (under variation of criterion) integer designs is suggested. Some examples are given for dimensions 4, 5 and 6.     

Recursive techniques for the construction of experimental designs

The construction of experimental designs by recursive techniques is studied in this paper. Formulae for the recursive addition or deletion of data from a design are derived for a typical sub-hypothesis situation of a general experimental design. These results are used to consider the recursive construction of experimental designs with respect to different optimality criteria. This approach to the construction of designs is quite different to that of the well-established theory of optimal design.

Investigating the impact of violations of the “left and top means first” heuristic on response behavior and data quality

ABSTRACT

Web surveys are an established data collection mode that use written language to provide information. The written language is accompanied by visual elements, such as presentation formats and shapes. However, research has shown that visual elements influence response behavior because respondents sometimes use interpretive heuristics to make sense of the visual elements. One such heuristic is the ‘left and top means first’ (LTMF) heuristic, which suggests that respondents tend to believe that a response scale consistently runs from left to right or from top to bottom. We conducted a web survey experiment to investigate how violations of the LTMF heuristic affect response behavior and data quality. For this purpose, a random half of respondents received response options that followed a consistent order and the other half received response options that followed an inconsistent order. The results reveal significantly different response distributions between the two groups. We also found that inconsistently ordered response options significantly increase response times and decrease data quality in terms of criterion validity. We, therefore, recommend using options that follow the design strategies of the LTMF heuristic.
