Objectives The current challenges of psychiatric nosology and semiology are part of an interdisciplinary and integrative framework. The paradigm of the personalized and precision psychiatry proposes to study this discipline according to new approaches and methodologies.

To our knowledge, there is no systematic exploration of the literature on the application of the concepts of personalized and precision medicine in the field of psychiatry. This article proposes thus to explore the framework of personalized and precision medicine applied to psychiatry. Methods We explored the framework of personalized and precision medicine applied to psychiatry by a textual network analysis. Firstly, we performed a systematic text-mining (Natural Language Processing) from an exhaustive review of the international literature with the terms “precision psychiatry” and “personalized psychiatry”. Secondly, this analysis of textual data allowed us to build a textual network which made it possible to visualize the most proximal terms (the most frequently associated in the literature). Finally, we extracted from the network the main dimensions explored in the scientific literature, and we studied the relative importance of each term by analyzing the network centrality. In addition, a brief bibliometric analysis was conducted. Results We show that personalized and precision psychiatry refers to six dimensions found in the textual network analysis which correspond to the scientific fields which study personalized and precision psychiatry: genetics, pharmacogenetics, artificial intelligence, therapeutic trials, biomarkers and staging. We explore how each dimension relates to the mechanization of psychiatric disorders. However, precision and personalized psychiatry, which tries to refine the levels of mechanistic explanations for psychiatry, suffers from a conceptual heterogeneity. Indeed, textual analysis also allows us to find terms referring to a set of heterogeneous concepts. Many methodological fields and epistemological concepts are invoked in this literature, without standardization. Conclusions The paradox of personalized and precision psychiatry is to associate a strong conceptual heterogeneity with a well-defined mechanistic component. Heterogeneity found in literature on personalized and precision psychiatry testifies to the lack of a pluralist and integrative theoretical framework. This framework could be based on a naturalizing but non-reducing formalism, aware of the societal challenges of the sciences and their implementation in the research and clinical systems of psychiatry.}, keywords = {tag1}, pubstate = {published}, tppubtype = {article} } Objectifs. – La médecine personnalisée et de précision nécessite une clarification des concepts qui y sont rattachés.

According to the ILO definition, decent work involves a wide range of conditions linked between them that include and go beyond farming work (e.g. gender equity, workplace security, fair income, among others). This complex situation requires for scientists the analysis of the diverse topics, as well as the development of interdisciplinary approaches to deal with this diversity. A review of the scientific literature is necessary to summarize the knowledge that has been produced and identify the current trends related to work in agriculture. In order to provide a background in this topic, the aim of this study was to review the state of the international literature related to work in agriculture, through a bibliometric analysis of scientific articles indexed in Scopus bibliographical database. Our findings show that USA, UK, France and China are the leaders in the scientific landscape according to: geographical production of knowledge, main journals and authors, and most-cited articles. The analysis of work in agriculture is declined in five main research domains: 1) social issues in rural areas; 2) labor market; 3) household strategies of labor allocation, 4) work organization in livestock farms; and 5) occupational health in farms. These research domains are investigated by four main scientific communities that prevail in the international literature: 1) agricultural economics; 2) ergonomics; 3) social issues for rural development; and 5) livestock farming systems. Besides those mainstream research, three major research trends emerged: 1) migration and precarious employment condition; 2) work issues in advisory services; and 3) labor governance in global value chains. These trends reflect ongoing transformations in agriculture that are important to think about the future of the work in this sector and its impacts on sustainable development.

By analysing Amazon’s financial statements, scientific publications and patents, we show that Amazon’s economic power heavily relies on its systematic innovations and capacity to centralize and analyse customized data that orients its business and innovations. We demonstrate how Amazon’s innovation activities have evolved over time with growing importance of technologies related to data and machine learning. We also map Amazon’s innovation networks with academic institutions and companies. We show how Amazon appropriates intellectual rents from these networks and from technological cooperation with other intellectual monopolies. We argue that Amazon, as other data-driven monopolies, predates value from suppliers and third-party companies participating in its platform. One striking characteristic of Amazon is the low rate of reported profits. The centrality of innovations leads us to suggest an alternative calculation that shows that Amazon’s profits are not as low as they appear in Annual Reports. We also argue that lower profits are coherent with Amazon’s rentiership and predatory strategy since they contribute to the avoidance of accusations of excessive market power. Finally, the paper offers preliminary observations on: (i) the complementarities between financial and intellectual rentierism and (ii) how data-driven intellectual monopoly expands big corporations’ political power.

This new knowledge, from one side, assigns to the city the new posthuman image of a smart system; from the other side, the polyphony of data-sources interferes with the narrative structure of the city, increasing its complexity and multiplying both the possibilities of its explorations as the management and design of its futures. In fact, the integration of digital tools for the collection, analysis and visualization of data enables the simulation of possible transformation scenarios. But how this system of fluctuating parameters relates to the physical space of the city? How these multiple virtual possibilities change the urban narrative? The intersection between digital mediation and physical urban space is the object of this paper, that moves from an interdisciplinary perspective, between narratology and urban design. We analyzed three case studies (Saint Petersburg, Bologna, Barcelona), representative of how the use of digital technologies transforms the representation of the city. In Saint Petersburg we have reshaped the (semantic) landscape of the city through Instagram data; in Bologna we have followed the (digital) traces of the temporary community of students, investigating the interaction and interference between the ‘univercity’ and the physical urban environment; in Barcelona we have analyzed an urban fragment (the street of La Rambla), considering it as a microcosmos of data.}, keywords = {tag1}, pubstate = {published}, tppubtype = {article} } The massive presence and use of digital technologies in urban areas generate a growing amount of data. This new knowledge, from one side, assigns to the city the new posthuman image of a smart system; from the other side, the polyphony of data-sources interferes with the narrative structure of the city, increasing its complexity and multiplying both the possibilities of its explorations as the management and design of its futures. In fact, the integration of digital tools for the collection, analysis and visualization of data enables the simulation of possible transformation scenarios. But how this system of fluctuating parameters relates to the physical space of the city? How these multiple virtual possibilities change the urban narrative? The intersection between digital mediation and physical urban space is the object of this paper, that moves from an interdisciplinary perspective, between narratology and urban design. We analyzed three case studies (Saint Petersburg, Bologna, Barcelona), representative of how the use of digital technologies transforms the representation of the city. In Saint Petersburg we have reshaped the (semantic) landscape of the city through Instagram data; in Bologna we have followed the (digital) traces of the temporary community of students, investigating the interaction and interference between the ‘univercity’ and the physical urban environment; in Barcelona we have analyzed an urban fragment (the street of La Rambla), considering it as a microcosmos of data. |

Many health providers utilize this media to disseminate health information. Patient use of social media for mental health topics encourages providers to disseminate quality information and to develop virtual collaborative learning environments. Such social media could also be seen as a reflection of a trend towards folk psychology. This study explored trends in health information exchanged by users of Twitter, a broad social media, through analyses of tweets about Autism Spectrum Disorder (ASD). This proxy of trends in folk psychology could be compared semantically with the corpus derived from biomedical research. Methods: At first, we conducted a text-mining analysis with a sample of 10,000 tweets posted using #autism, by a text-mining method. We built a network of words in order to extract the main dimensions about these data (Latent Dirichlet Analysis). Second, we performed a geocoding analysis to create a Twitter maps of social media tweet and checked the regularity of tweets in the short and medium term. In parallel, we performed a text-mining analysis using the platform PubMed with the term « autis* », and we built networks of words. For each of them, we extracted the main dimensions from the terms. Results: We were able to retrieve 121,556 terms related to the term #autism. Most tweets focus on five dimensions: (1) Education, (2) Childhood, (3) Environment/Relatives, (4) Techniques/Sciences and (5) Support. Concerning the most researched topics in the biomedical research, on 49,021 publications, we found four dimensions: (I) Clinical/Neuropsychology/Psychometry, (II) Behavioral/Language aspects, (III) Neuroscience/Neurogenetics/Neuropharmacology, (IV) Comorbidities. Conclusion: Results suggest thematics about ASD disseminated between a social media and a biomedical database are really different. Health providers are encouraged to establish a presence on social media to learn about representations, share scholarly work or just exchange information with patients and relatives concerned by ASD.}, keywords = {tag1}, pubstate = {published}, tppubtype = {article} } Aim: Twitter is the most commonly used social media forum in public health and is considered the radio of the internet.
