“间接确证”能实现对“不充分决定命题”的反驳吗?——劳丹与利普林论经验等值与不充分决定命题

典型的"不充分决定命题"以经验等值问题为理论基础,强调经验证据对理论的不充分决定作用.经验等值命题又是以传统的"假说演绎"模型为依据的,它的论证表现为一种"直接确证假设",其根据在于假说演绎理论的"后承主义".劳丹和利普林针对亨普尔式的逆后承条件,从反驳直接确证入手,提出了"间接确证"论证,试图直接截断从经验等值到不充分决定命题的逻辑关联.但劳丹等人的间接确证还存在很多问题,而且违背了确证理论中"逆后承条件"和"确证的充分性条件"的不相容性.     

叙述者的陷阱——谈《尘埃落定》叙述者的介入

从叙事学的理论出发，主要分析《尘埃落定》中的叙述者功能，看到了这个“第一人称叙述者”在一种主观全知全能支配下，对整个故事情节的推动作用；同时，透过叙述者的功能，发现了隐藏在后面更深的文本叙述者的中心力量，从而确定了叙述者在小说中的核心作用。     

Validating a short version of the Suicide Intent Scale in China

As Beck's Suicide Intent Scale (SIS) gains popularity in various areas in the world, we are not sure whether the scale is an optimal measure of suicide intent in the Chinese culture. This study is to provide evidence to support the use of the Chinese shortened version of SIS (C-SIS) in Chinese societies. The data were from applying the C-SIS in a psychological autopsy (PA) study of 66 suicides in Dalian, China. Reliability and validity tests were performed on the C-SIS data. Internal consistency analysis showed excellent correlation coefficients for all items but one. Inter-rater reliability tests showed statistically significant correlations between each pair of informants for each item and for the total scores. Criterion validity analysis demonstrated a relatively high correlation between the scores on the Hamilton Depression Rating Scale (HAM-D) and C-SIS. Factor analysis produced three factors accounting for 66.77% of the total variance. The study suggested that C-SIS should be an appropriate instrument for detecting and measuring suicide intent in Chinese societies.     

Research on Green and Low-Carbon Development Path of China's Automotive Industry

China’s automotive industry has been dedicated to a series of carbon-reduction efforts and has strived for comprehensive green and low-carbon transformation in order to achieve carbon peaking and carbon neutrality goals. On the basis of automobiles’ whole life-cycle(WLC) carbon emission accounting, this paper calculates life-cycle carbon emissions per vehicle, proposes green and low-carbon development path for China’s automotive industry, quantifies and analyzes implicated carbon-reduction poten...
