Identification of single-site gold catalysis in acetylene hydrochlorination

There remains considerable debate over the active form of gold under operating conditions of a recently validated gold catalyst for acetylene hydrochlorination. We have performed an in situ x-ray absorption fine structure study of gold/carbon (Au/C) catalysts under acetylene hydrochlorination reaction conditions and show that highly active catalysts comprise single-site cationic Au entities whose activity correlates with the ratio of Au(I):Au(III) present. We demonstrate that these Au/C catalysts are supported analogs of single-site homogeneous Au catalysts and propose a mechanism, supported by computational modeling, based on a redox couple of Au(I)-Au(III) species.

Calculating the value of the commons: Generating resilient urban futures

In this article, we present a method for valuing the multidimensional aspects of urban commons. This method draws from and contributes to a broader conception of social or community returns on investment, using the case and data of a vibrant project, strategy, and model of ecological resilience, R‐Urban, on the outskirts of Paris. R‐Urban is based on networks of urban commons and collective hubs supporting civic resilience practices. We use data from 2015, the year before one of the hubs was evicted from its site by a municipal administration that could not see the value of an “urban farm” compared to a parking lot. We combine estimates of the direct revenues generated for a host of activities that took place in R‐Urban, including an urban farm, community recycling centre, a greenhouse, community kitchen, compost school, café, a teaching space, and a mini‐market. We then estimate the market value of volunteer labour put into running the sites, in addition to the value of training and education conducted through formal and informal channels, and the new jobs and earnings that were generated due to R‐Urban activity. Finally, we estimate the monetary value of the savings made by an environmentally conscious design that focused on water recycling, soil and biodiversity improvement, and social and health benefits, breaking them down by savings to the organization, participants and households involved in R‐Urban itself, as well as savings to the state and the planet. Although our article is built on specific quantities from a concrete project, the method has wide applicability to urban commons of many types seeking to demonstrate the worth and value of all their many facets and activities

The discomforting rise of ' public geographies': a 'public' conversation.

In this innovative and provocative intervention, the authors explore the burgeoning ‘public turn’ visible across the social sciences to espouse the need to radically challenge and reshape dominant and orthodox visions of ‘the academy’, academic life, and the role and purpose of the academic

Transnational reflections on transnational research projects on men, boys and gender relations

This article reflects on the research project, ‘Engaging South African and Finnish youth towards new traditions of non-violence, equality and social well-being’, funded by the Finnish and South African national research councils, in the context of wider debates on research, projects and transnational processes. The project is located within a broader analysis of research projects and projectization (the reduction of research to separate projects), and the increasing tendencies for research to be framed within and as projects, with their own specific temporal and organizational characteristics. This approach is developed further in terms of different understandings of research across borders: international, comparative, multinational and transnational. Special attention is given to differences between research projects that are in the Europe and the EU, and projects that are between the global North and the global South. The theoretical, political and practical challenges of the North-South research project are discussed

Economies of space and the school geography curriculum

This paper is about the images of economic space that are found in school curricula. It suggests the importance for educators of evaluating these representations in terms of the messages they contain about how social processes operate. The paper uses school geography texts in Britain since the 1970s to illustrate the different ways in which economic space has been represented to students, before exploring some alternative resources that could be used to provide a wider range of representations of economic space. The paper highlights the continued importance of understanding the politics of school knowledge

Extensive Spectroscopy and Photometry of the Type IIP Supernova 2013ej

We present extensive optical ($UBVRI$, $g'r'i'z'$, and open CCD) and near-infrared ($ZYJH$) photometry for the very nearby Type IIP SN ~2013ej extending from +1 to +461 days after shock breakout, estimated to be MJD $56496.9\pm0.3$. Substantial time series ultraviolet and optical spectroscopy obtained from +8 to +135 days are also presented. Considering well-observed SNe IIP from the literature, we derive $UBVRIJHK$ bolometric calibrations from $UBVRI$ and unfiltered measurements that potentially reach 2\% precision with a $B-V$ color-dependent correction. We observe moderately strong Si II $\lambda6355$ as early as +8 days. The photospheric velocity ($v_{\rm ph}$) is determined by modeling the spectra in the vicinity of Fe II $\lambda5169$ whenever observed, and interpolating at photometric epochs based on a semianalytic method. This gives $v_{\rm ph} = 4500\pm500$ km s$^{-1}$ at +50 days. We also observe spectral homogeneity of ultraviolet spectra at +10--12 days for SNe IIP, while variations are evident a week after explosion. Using the expanding photosphere method, from combined analysis of SN 2013ej and SN 2002ap, we estimate the distance to the host galaxy to be $9.0_{-0.6}^{+0.4}$ Mpc, consistent with distance estimates from other methods. Photometric and spectroscopic analysis during the plateau phase, which we estimated to be $94\pm7$ days long, yields an explosion energy of $0.9\pm0.3\times10^{51}$ ergs, a final pre-explosion progenitor mass of $15.2\pm4.2$~M$_\odot$ and a radius of $250\pm70$~R$_\odot$. We observe a broken exponential profile beyond +120 days, with a break point at +$183\pm16$ days. Measurements beyond this break time yield a $^{56}$Ni mass of $0.013\pm0.001$~M$_\odot$.Comment: 29 pages, 23 figures, 15 tables, Published in The Astrophisical Journa

Performing Values Practices and Grassroots Organizing: The Case of Solidarity Economy Initiatives in Greece

This article discusses solidarity economy initiatives as instances of grassroots organizing, and explores how ‘values practices’ are performed collectively during times of crisis. In focusing on how power, discourse and subjectivities are negotiated in the everyday practices of grassroots exchange networks (GENs) in crisis-stricken Greece, the study unveils and discusses three performances of values practices, namely mobilization of values, re-articulation of social relations, and sustainable living. Based on these findings, and informed by theoretical analyses of performativity, we propose a framework for studying the production and reproduction of values in the context of GENs, and the role of values in organizing alternatives

The tactical mimicry of social enterprise strategies: acting ‘as if’ in the everyday life of third sector organizations

Using England as a paradigmatic case of the „enterprising up ‟ of the third sector through social enterprise policies and programs, this article sheds light on resistance as enacted through dramaturgical identification with government strategies. Drawing from a longitudinal qualitative research study, which is interpreted via Michel de Certeau‟s theory of the everyday, we present the case study of Teak, a charitable regeneration company, to illustrate how its Chief Executive Liam „acted as ‟ a social entrepreneur in order to gain access to important resources. We establish „tactical mimicry ‟ as a sensitizing concept to suggest that third sector practitioners ‟ identification with the normative premises of „social enterprise ‟ is part of a parasitical prosaics geared toward appropriating public money. While tactical mimicry conforms to strategies only in order to exploit them, its ultimate aim is to increase potentials of collective agency outside the direct influence of power. The contribution we make is threefold: first, we extend the recent debate on productive resistance by highlighting how „playing the game ‟ without changing existing relations of power can nevertheless produce largely favorable outcomes. Second, we suggest that recognition of the productive potential of tactical mimicry requires methodologies which pay attention to the spatial and temporal dynamics of resistance. And third, we argue that explaining „social enterprise‟ without consideration of the non-discursive, mainly financial resources made available to those who identify with it, necessarily risks overlooking a crucial element of the dramaturgical dynamic of discourse
