应对数字艺术公共安全隐患的立法策略研究

当下数字艺术的产生和迅速崛起从根本上改变了原子艺术长期以来建构起来的艺术生态和艺术秩序,引发了某些引起人们重大关切的公共安全问题,其中突出的有网瘾问题、网络文化低俗化问题、数字谣言问题以及数字艺术知识产权保护问题等。这些问题不同于原子艺术公共安全隐患发生学上的外生性、随机性和个别性,而是呈现为内生性、公共性、流行性和危害性特征。一条比较可行的防控策略是在对数字艺术实施事前立法规范的同时,对数字艺术公共安全机制同步实施事后追溯监管。此外,加强数字艺术公共安全性及其应对机制的科研攻关和科普宣传,尽快提高全社会对数字艺术特殊规律及其公共安全性的认识和了解也是当务之急。

The trouble with ‘women in computing’: a critical examination of the deployment of research on the gender gap in computer science

The pessimistic scenario for ‘women in information communications technology’ and for ‘women in technology’ generally is even more paradoxical and insidious with respect to ‘women in computing’. Studies within this field not only report insignificant improvement in the proportion of women in Western countries’ computing fields but also alert us of a declining trend. Moreover, that decline has been accompanied – or even preceded – by years of research and programs that have specifically focused on increasing women’s participation in computing; however, they have not had the expected effect. More surprisingly, there has been a significant increase in the representation of women in all other science-related fields and professions. Our aim is to provide some clues to fight the feeling of inexorability that may be entailed by the research on women in computing. We will argue that part of the problem is related to the static nature of the research deployed around the problem of ‘women in computing’, primarily, the research constructed around the ‘leaky pipeline’ metaphor. We provide a synthesis of the critiques this research has received in recent decades and highlight research trends that render other landscapes visible when studying ‘women in computing’. These trends help us question how we are conducting research within this field and urge us to problematise assumptions about computing and gender that we may paradoxically continue to reproduce even while denouncing the paucity of women in computing and studying the reasons for this state of affairs. In short, we present the need for different researchers’ eyes that allow different landscapes of women and computing to be seen and produced.

Metrological framework for selecting morphological characters to identify species and estimate developmental maturity of forensically significant insect specimens

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.

Key points

• Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
• Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
• These metrological principles also apply to individuation of unique objects in general.
