Нові документи про родину Лисянських

Het lijkt een wet van Meden en Perzen: in tijden van crisis duikt ook steeds een roep om ingrijpende verandering op. Constante in deze dynamiek is het concept van de rechtvaardige stad. Hoewel al in de jaren zeventig geïntroduceerd, is het nog steeds onderdeel van verhit debat. In deze AGORA een historische en theoretische refl ectie en een analyse van rechtvaardigheid in de stedelijke praktijk

Молодь і політика: соціологічні парадокси та українські реалії

The exchange of phosphatidylcholine between intact human or rat erythrocytes and rat liver microsomes was greatly stimulated by phosphatidylcholine-specific exchange proteins from rat liver and beef liver. It was found, however, that compared to the exchange reaction between phospholipid vesicles and rat liver microsomes, much higher concentrations of exchange protein were required in the case of intact red blood cells and microsomes. In human erythrocytes, 75% of the phosphatidylcholine was available for exchange within 2 h at 37°C. No additional exchange was observed during the next 2 h, indicating slow, if any, transbilayer movement of the residual phosphatidylcholine. In rat erythrocytes 50-60% of the phosphatidylcholine was readily available for the exchange proteins. The residual phosphatidylcholine was exchanged at a much lower rate with a half time for equilibration of 7 h. These results confirm in an independent way the asymmetric distribution of phosphatidylcholine over the membrane of human and rat erythrocytes as well as the occurrence of a slow transbilayer movement of this lipid in rat erythrocytes

Social Space and Social Media: Analyzing Urban Space with Big Data

This dissertation focuses on the key role that big data can play in minimizing the perceived disconnect between social theory and quantitative methods in the discipline of geography. It takes as its starting point the geographic concept of space, which is conceptualized very differently in social theory versus quantitative methodology. Contrary to this disparity, an examination of the disciplinary history reveals a number of historic precedents and potential pathways for a rapprochement, especially when combined with some of the new possibilities of big data. This dissertation also proposes solutions to two common barriers to the adoption of big data in the social sciences: accessing and collecting such data and, subsequently, meaningful analysis. These methods and the theoretical foundation are combined in three case studies that show the successful integration of a quantitative research methodology with social theories on space. The case studies demonstrate how such an approach can create new and alternative understandings of urban space. In doing so it answers three specific research questions: (1) How can big data facilitate the integration of social theory on space with quantitative research methodology? (2) What are the practical challenges and solutions to moving “beyond the geotag” when utilizing big data in geographical research? (3) How can the quantitative analysis of big data provide new and useful insight in the complex character of social space? More specifically, what insights does such an analysis of relational social space provide about urban mobility and cognitive neighborhoods

The Messiah on Netflix: between confusion and inspiration

Abstract The Netflix series The Messiah has intrigued many spectators but has encountered criticism as well. The criticism is heterogeneous: both concerned Christians, often from American protestant background, as well as sceptic secular people have rejected person and message of the mysterious al-Masiḥ. In our article it is shown that this kind of criticism should be considered part and parcel of the Messianic impact of the series. By a careful comparison between Islamic and Christian Messianic motifs it becomes clear that the series has consciously found its way amids a plethora of motifs, hereby avoiding violent and intolerant elements of classical Messianism, although apocalyptic elements are not lacking either. The device exploited frequently is „the rhetorics of evasion and of confrontation‟, by which the search for truth falls back upon the follower him- or herself. Human existence is viewed as a struggle between the superficial and the existential, as well as between the self-assured and the wounded. Al-Masiḥ seems to be capable of confronting the people with the deeper layers of their existence, while transcending barriers of religion, politics and class

Organizing Networked Learning

A networked context is dynamic. In this paper, I set up the organization of learning in a networked context starting from four leads. The first lead is analyzing involvement and acting as an example of a network. We view the network as a unit of analysis and the core of the network is the initiative. We make use of the involvement that the initiative radiates and attracts. I present the network analysis model as a means to order involvement and to identify different positions within a network. I also provide a vocabulary to communicate about them. The second lead is communicating knowledge and acting as an example of a node. We view the network as a knowledge infrastructure of nodes and links, that irrespective of size or capability provide access to knowledge in their own way. This is called a nodal network. The third lead is preparing effort and acting as an example of environment. We view the network as an inviting and challenging space in which various initiatives and networks come together, explore relationships, experiment, share and attune. An aid to creating an inviting environment is turning something into a theme. To create space we invite a diversity of related initiatives and networks to come together and learn from each other. The fourth and last lead is facilitating abilities and acting as an example of a programme. When we translate network into programme, we see a tissue of layers, lines, episodes and moments in which parties act, knowledge arises, effort emerges and the ability of the network to handle issues evolves into strategies, improvisations, habits and routines. Together, these leads offer a tangible steering framework for following and leading the otherwise so diffuse concept of 'network'. By unravelling 'network' the way I propose here, we can find the leads to establish relationships, handle the dynamics and learn to organize in a networked context. This paper approaches learning in a networked context as a matter of organization and explores the leads that allow us to act in a networked context. After describing the four leads I present some cases and the issues they give rise to. These I consider my questions for further research. I conclude with some general remarks about the organization of networked learning

Pandemic polycentricity? Mobility and migration patterns across New York over the course of the Covid-19 pandemic

Abstract: The expectation of a mass movement out of cities due to the rise of remote work associated with the Covid-19 pandemic, is counter to longstanding theories of the benefits of agglomeration economies. It suggests centrifugal shifts of economic activity which could boost neighbourhood economies at the expense of the downtown core. Using mobile phone data from SafeGraph, we track migration and daily mobility patterns throughout the New York metropolitan area between July 2019 and June 2021. We find that diverse suburban centres and exurban areas have bounced back more quickly than the dense specialised commercial districts in and around Manhattan

Attentional Social Media: Mapping the Spaces and Networks of the Fashion Industry

In this article we use big data methods to analyze the attention paid to the fashion industry on social media. The article argues that for the fashion industry, like many industries, the core product is a form of knowledge that is dependent on gaining and holding people’s attention. To understand this attentional economy, social media offers a unique window because it is increasingly a central space within which fashion knowledge is created and shared. Using long-term, geotagged big data from Twitter, we analyze the hitherto difficult-to-explore spaces and places of the global fashion industry. The article suggests that the data confirm the ideas that there are a series of global fashion capitals that are especially important to the industry and that attention paid to fashion is highly uneven and varied across industry functions, national origins, and companies. Evidence is presented that attention to fashion is a global phenomenon that does not always directly link to where fashion products are sold. Attention to fashion is both a market-making mechanism for the industry as well as an indicator of wider social and cultural processes of tastemaking and identity formation within which fashion is entwined. The article concludes by suggesting that such data offer geographers new ways of looking at and linking economic, social, and cultural spaces and geographies and that social media analysis can help bridge boundaries that divide geographers
