Social media as semiotic technology and social practice: the case of ResearchGate’s design and its potential to transform social practice

ABSTRACT

This article addresses the need for critical approaches to social media by bridging the focus on language and other semiotic resources that characterises discourse studies with the broader perspective on social media as social, cultural, economic and technological constructs that dominates media and cultural studies. Specifically, we propose a model for analysing how social media as semiotic technologies, that is, technologies designed to enable and constrain meaning-making, may transform social practices. By incorporating Van Leeuwen’s [2008. Discourse and Practice: New Tools for Critical Analysis. London: Oxford University Press] framework for the critical analysis of discourse and social practice, the model extends the social semiotic approach developed in recent critical multimodal studies of software such as PowerPoint to social media, which function primarily to provide platforms for and commodify social practices, rather than to offer rich arrays of semiotic resources for creating multimodal texts and artefacts. Using the academic social network site ResearchGate and the practice of research peer review, we illustrate the model’s capacity to account for the ways the design of social media platforms – through the semiotic resources they make available and the ways these are presented – enables and constrains their users’ ability to perform key social practices and has the potential to transform these practices.     

仲裁裁决在撒哈拉以南非洲的执行

本文对非洲大陆撒哈拉以南地区国家法院对仲裁裁决的执行作了考察。撒哈拉以南非洲国家的仲裁制度可以分为三个大的部分:属于OHADA体制的国家;实施了1958年《纽约公约》以及/或其仲裁法是根据联合国国家贸易法委员会《示范法》为模本而制定的国家;以及既没有实施《纽约公约》,也没有采纳《示范法》,并且也不是OHADA成员国的国家。文章对这三个法域承认与执行外国仲裁裁决的理由以及撤销外国仲裁裁决的理由作了探讨。     

Toward Developing a Structured Approach to the Diagnosis and Resolution of Nonperforming Loans: The Case of China and India1

This article addresses the issue of nonperforming loans (NPLs) from a public policy perspective. The focus is on three aspects of NPLs that we consider essential for a proper analysis: the degree of the NPL problem, the causes of NPLs and the solutions adopted to address an identified NPL issue. This research analyses the diverse definitions and measurements of an NPL. Further, it introduces the distinction between systemic and situational causes of NPLs. Arguing that different causes require different cures, this study emphasizes a mix of short‐term and long‐term remedial measures as judicious in dealing with the NPL problem. This framework is then applied to two case studies: China and India. The conclusion identifies future directions of research, such as the study of a threshold level beyond which NPLs may pose a barrier to a country's growth and productivity.     

Analysis of friction ridge evidence for trace amounts of paracetamol in various pharmaceutical industries by Raman spectroscopy

The detection of potentially harmful substances presents a multifaceted challenge. On one hand, it can directly save lives, on the other, it can significantly aid and enhance police work, thereby increasing the effectiveness of investigations. The research conducted in this study primarily aims to identify paracetamol in fingerprints, considering situations involving direct contact of a person with paracetamol either chronically or in a single dose. The identification procedure presented, utilizing Raman spectroscopy, aims to rapidly detect the xenobiotic following ingestion by an individual, which involves touching the tablet with their fingers—this can be termed as touch evidence in forensic science investigations. Additionally, the authors focus on assessing the impact of additives present in drugs containing paracetamol as the main active ingredient. The screening results obtained will enable us to analyze the composition of drugs in terms of potentially toxic substances, and their influence on the physicochemical activity of the active substance. We successfully identified the paracetamol molecule using a noninvasive forensic trace detection method. Samples in the form of common drugs containing 500 mg of paracetamol were studied. Throughout the study, comprehensive validation of the method was ensured through the utilization of a statistical model, which excluded sensitivity to the presence of other substances, whether additives or from the external environment. The proposed approach to trace the content of substances in fingerprint using Raman scattering analysis provides a useful starting point to enhance current analytical methods not only in forensic science but also in toxicology.
