‘You shouldn’t be making people feel bad about having sex’: exploring young adults’ perceptions of a sex-positive sexual health text message intervention

Young adults are disproportionately affected by negative sexual health outcomes, such as sexually transmitted infections. One strategy for reducing such negative outcomes involves the use of comprehensive sexual health education. As comprehensive sexual health education programmes are adopted, there is a need to evaluate the messaging approaches that might best connect with young people. Sex-positive approaches, which describe sex as a healthy practice and personal choice, are becoming popular, but whether this strategy works has not been tested from a message design perspective. This study examines the reactions of young adults to sex-positive or sex-negative messages, framed as a gain or loss, designed for a text message-based intervention. Participants quantitatively evaluated 24 messages on their mobile phones. Gain frames were preferred over loss frames, and sex-positive messages were rated as more believable and persuasive. An interaction between the two concepts was also found. Results highlight how sex-positive messages that focus on the benefits of certain behaviours tend to resonate better with young adults. Implications for health educators and practitioners are discussed.     

Going with the affective flows of digital school absence text messages

Focusing on digital text messages containing information about students’ absences and sent to parents by schools, the paper investigates the way school absenteeism is produced within affective assemblages. The paper unfolds a theoretical and methodological approach of ‘going with’ the text messages, in entanglements of affective flows. The empirical engagements, produced together with multiple agents in two Swedish schools, show that within the assemblages of human and nonhuman bodies, the text messages can become ‘stirrers’ that evoke nervousness and anxiety, but also excitement and feelings of control that affect the production and conception of absenteeism. The affective flows of text messages thus travel in all directions, with and against notions of linearity. The conclusion emphasizes how the text messages, as affective materialities, are an inextricable part of the production of school absenteeism in multiple and sometimes unexpected ways.

基于功能分析的专利技术产业化适用性研究

本文在梳理概括了国内外专利文本挖掘技术研究进展基础上,探索建立一种基于对专利文本中特定动宾(AO)结构进行挖掘分析的专利功能分析方法,并通过专利功能的定义、提取和分析将专利技术与相关产业进行对接,实现了从专利文本中识别产业化的潜在领域。更为重要的是,本文提出了描述专利技术功能效用的S曲线和S指数,完善和改进了专利技术产业化适用性量化评价模型,并定义了该模型中的S指数、专利功能的绝对重要性指数(AI)和专利功能的相对重要性指数(RI)三个评价指标。最后,以具备"reduce PM2.5"功能的专利为例,验证了基于功能分析的专利技术产业化适用性评价模型的可行性,为中国专利技术产业化路径选择提供了新思路。     

Dictionary-based text categorization of chemical web pages

A new dictionary-based text categorization approach is proposed to classify the chemical web pages efficiently. Using a chemistry dictionary, the approach can extract chemistry-related information more exactly from web pages. After automatic segmentation on the documents to find dictionary terms for document expansion, the approach adopts latent semantic indexing (LSI) to produce the final document vectors, and the relevant categories are finally assigned to the test document by using the k-NN text categorization algorithm. The effects of the characteristics of chemistry dictionary and test collection on the categorization efficiency are discussed in this paper, and a new voting method is also introduced to improve the categorization performance further based on the collection characteristics. The experimental results show that the proposed approach has the superior performance to the traditional categorization method and is applicable to the classification of chemical web pages.
