In/Visible Space
No full textIn/visible Space is a series of photographic essays documenting the use of dress and self-created queer spaces of six young South Asian Lesbian, Bisexual, Transgender and Queer (LBTQ) self-identified women and Transgender, non-binary persons in Britain, and the transformative healing processes it produced, experienced as spatial affect. It explores how South Asian LBTQ persons assert their queer and diasporic identities, either in public or private spaces, using cross-cultural dress markers to subvert normative standards of western dress. The project questions how South Asian LBTQ youth, specifically women and minority genders, construct their identities through dress in their lives at home, and aims to counteract the dominant landscape of whiteness, prevalent in mainstream LGBT and queer culture in the UK. Lipi Begum and Rohit K. Dasgupta met up with the artist Raisa S. Kabir to discuss her practice and motivations for this project. The conversation has been lightly edited for clarity
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Valuation and Evaluation: Measuring the Quality of Life and Evaluating Public Policy
No full textThis paper is about measuring social well-being and evaluating policy. Section 1 concerns the links between the two, while Sections 2 and 3, respectively, are devoted to the development of appropriate methods for measuring and evaluating. In Section 2 I identify a minimal set of indices for spanning a general conception of social well-being. The analysis is motivated by the frequent need to make welfare comparisons across time and communities. A distinction is drawn between current well-being and sustainable well-being. Measuring current well-being is the subject of discussion in Sections 2.2-2.3. It is argued that a set of five indices, consisting of private consumption per head, life expectancy at birth, literacy, and indices of civil and political liberties, taken together, are a reasonable approximation for the purpose at hand. Indices of the quality of life currently in use, such as the United Nations Development Programme’s (UNDP) Human Development Index, are cardinal measures. Since indices of civil and political liberties are only ordinal, aggregate measures of social well-being should be ordinal. In this connection, the Borda index suggests itself. In Section 2.3 the Borda index is used on data from 46 of the poorest countries in the early 1980s. Interestingly, of the component indices, the ranking of the sample countries in terms of life expectancy at birth is the most highly correlated with the countries' Borda ranking. Even more interestingly, the ranking of countries in terms of gross national product (GNP) per head is almost as highly correlated. There can be little doubt that this finding is an empirical happenstance. But it may not be an uncommon happenstance. If so, GNP per head could reasonably continue to be used as a summary measure of social well-being, even though it has no theoretical claims to be one. It is widely thought that net national product (NNP) per head measures the economic component of sustainable well-being. Section 2.4 and the Appendix show that this belief is false. NNP, suitably defined, can be used to evaluate economic policies, but it should not be used to make intertemporal and cross-country comparisons of the standard of living. In particular, comparisons of sustainable welfare should involve comparisons of wealth. For the purposes of comparing social well-being in an economy over time, often, one would analyze whether net investment is positive, negative, or nil. Writings on the welfare economics of NNP have mostly addressed economies pursuing optimal policies, and are thus of limited use. The analysis in Section 2.4 and the Appendix generalizes this substantially by studying environments where governments are capable of engaging only in policy reforms, in economies characterized by substantial non-convexities. The analysis pertinent for optimizing governments and convex economies are special limiting cases of the one reported here. In Sections 3.1-3.3 I explain that policy-evaluation techniques developed in the 1970s, while formally correct, neglected to consider (1) resource allocation in the wide variety of non-market institutions throughout the world, and (2) the role the environmental-resource base plays in society. It is argued that the evaluation of policy changes can be done effectively only if there is a fair understanding of the way socioeconomic and ecological systems would respond to the changes. The observation is no doubt banal, but all too often decisionmakers have neglected to model the combined socioeconomic and ecological system before embarking upon new policies or keeping faith in prevailing ones. Examples are provided to show that such neglect has probably meant even greater hardship for groups of people commonly regarded as particularly deserving of consideration. The examples are also designed to demonstrate how recent advances in the understanding of general resource allocation mechanisms and of environmental and resource economics can be incorporated in a systematic way into what are currently the best-practice policy evaluation techniques.
Self-induced temporal instability from a neutrino antenna
No full textIt has been recently shown that the flavor composition of a self-interacting neutrino gas can spontaneously acquire a time-dependent pulsating component during its flavor evolution. In this work, we perform a more detailed study of this effect in a model where neutrinos are assumed to be emitted in a two-dimensional plane from an infinite line that acts as a neutrino antenna. We consider several examples with varying matter and neutrino densities and find that temporal instabilities with various frequencies are excited in a cascade. We compare the numerical calculations of the flavor evolution with the predictions of linearized stability analysis of the equations of motion. The results obtained with these two approaches are in good agreement in the linear regime, while a dramatic speed-up of the flavor conversions occurs in the non-linear regime due to the interactions among the different pulsating modes. We show that large flavor conversions can take place if some of the temporal modes are unstable for long enough, and that this can happen even if the matter and neutrino densities are changing, as long as they vary slowly

Model-independent diagnostic of self-induced spectral equalization versus ordinary matter effects in supernova neutrinos
No full textSelf-induced flavor conversions near the supernova (SN) core can make the fluxes for different neutrino species become almost equal, potentially altering the dynamics of the SN explosion and washing out all further neutrino oscillation effects. We present a new model-independent analysis strategy for the next galactic SN signal that will distinguish this flavor equalization scenario from a matter-effects-only scenario during the SN accretion phase. Our method does not rely on fitting or modeling the energy-dependent fluences of the different species to a known function, but rather uses a model-independent comparison of charged-current and neutral-current events at large next-generation underground detectors. Specifically, we advocate that the events due to elastic scattering on protons in a scintillator detector, which is insensitive to oscillation effects and can be used as a model-independent normalization, should be compared with the events due to inverse beta decay of νe in a water Cherenkov detector and/or the events due to charged-current interactions of νe in an argon detector. The ratio of events in these different detection channels allow one to distinguish a complete flavor equalization from a pure matter effect, for either of the neutrino mass orderings, as long as the spectral differences among the different species are not too small
