description: We show that the Brill-Lindquist initial data provides a counterexample to a Riemannian Penrose inequality with charge conjectured by G. Gibbons. The observation illustrates a sub-additive characteristic of the area radii for the individual connected components of an outermost horizon as a lower bound of the ADM mass.
Kød, krop og identitet

description: Johanne Stubbe Teglbjærg Kød, krop og identitet – om betydningen af begrebet 'kød' i nyere protestantisk teologi. (Flesh, body and identity – about the meaning of the concept of flesh in new Protestant theology). The turning point of the article is incarnation itself. Since Antiquity flesh has played a central role in Christianity in the interpretation of the figure Jesus, and from a Protestant point of view the article describes the relevance for an understanding of the question of identity. In this tradition flesh functions as a middle position between the interior and the exterior, which has been interpreted in different ways through the history of theology. Four widespread interpretations are stressed here, before the article includes three contemporary and neoclassical trinity-theological positions from Paul Tillich, Jürgen Moltmann and Wolfhart Pannenberg. Finally the article offers its own suggestion of how the relationship between flesh and Christianity can be interpreted.

description: [abridged] Quasars (QSOs) at the highest known redshift (z~6) are unique probes of the early growth of supermassive black holes (BHs). Until now, only the most luminous QSOs have been studied, often one object at a time. Here we present the most extensive consistent analysis to date of z>4 QSOs with observed NIR spectra, combining three new z~6 objects from our ongoing VLT-ISAAC program with nineteen 4=-0.37 (Lbol/LEdd~0.43) with a scatter of 0.20 dex for the z>4 sample and the =-0.80 (Lbol/LEdd~0.16) with a scatter of 0.24 dex for the 0.354 sources are accreting significantly faster than the lower-redshift ones. We show that the derived FeII/MgII ratios depend sensitively on the performed analysis: our self-consistent, homogeneous analysis significantly reduces the FeII/MgII scatter found in previous studies. The measured FeII/MgII line ratios show no sign of evolution with cosmic time in the redshift range 4

description: Torben Kjersgaard Nielsen, At frådse i kropslighed – om krop og religion i middelalderen. (To gorge on carnality – about body and religion in the Middle Ages). The article examines how religious people in the European Middle Ages thought and talked about their bodies. One of the central points is that what we traditionally consider a medieval dualistic split between body and soul is not necessarily so unambiguous. Instead, many medieval thinkers distinguished between three spheres, body (corpus), spirit (spiritus) and soul (anima). The article exemplifies how in new translations this medieval understanding has been repressed. The article also discusses how the body has not just been negated, but rather used as a medium for religiosity. The article here introduces the concept of religious athletes, who showed a professional and conscious relationship to their bodies and the cultivation of them and the access to God through them.

description: Using high-resolution (~85000) and high signal-to-noise ratio (~200) optical spectra acquired with the European Southern Observatory Ultraviolet and Visual Echelle Spectrograph, we have determined the interstellar column densities of C2 for six Galactic lines of sight with E(B- V) ranging from 0.33 to 1.03. For our purposes, we identified and measured absorption lines belonging to the (1, 0), (2, 0) and (3, 0) Phillips bands A1Πu-X1Σ+g. We report on the identification of a few lines of the C2 (4, 0) Phillips system towards HD 147889. The curve-of-growth method is applied to the equivalent widths to determine the column densities of the individual rotational levels of C2. The excitation temperature is extracted from the rotational diagrams. The physical parameters of the intervening molecular clouds (e.g. gas kinetic temperatures and densities of collision partners) were estimated by comparison with the theoretical model of excitation of C2.

Elucidating the neurobiology of problem gambling using a novel rodent slot machine task.
Creators: name: Cocker, Paul J.
Publisher: name: University of British Columbia
Year: 2016

description: Gambling is an enjoyable and innocuous past-time for many, but for some it can become a maladaptive compulsion akin to drug or alcohol addiction. Despite increasing recognition that the phenomenological process underlying both substance and behavioural addictions may be similar, treatment options for problem gambling remain limited, and of questionable efficacy. Animal models offer an invaluable opportunity to not only study the underlying neurobiology of disorders such as gambling, but may also facilitate the development of novel pharmacotherapies. To that end we have developed a rodent slot machine task (rSMT) that suggests rats share key behavioural features with human gamblers. The dopamine D₂-like receptor family is critically involved in modulating animals’ performance on the rSMT. Specifically, the D₄ receptor appears to contribute to animals’ attributions of salience to game-related stimuli. D₄ receptors are principally located within prefrontal cortical regions and consequently represent an intriguing target for modulating higher order cognitive processes. In addition to systemic pharmacology, we have demonstrated that disruption of neural regions that are relatively rich in D₄ receptors, such as the anterior cingulate and insular cortex, impact animals’ ability to accurately respond to reward-related stimuli on the rSMT; further emphasising a role for these receptors in gambling-related decision making. Additionally, we have used the rSMT to try and model iatrogenic gambling observed in patients with Parkinson’s disease (PD). This form of compulsive gambling arises de-novo in a small but significant sub-set of patients following adjunctive therapy with D₂-like agonists. Chronic administration of a D₂/₃ receptor agonist galvanized performance on the rSMT, a finding that could be considered translationally analogous to the compulsive play exhibited by some PD patients. These alterations in performance were accompanied by an increase in the transcription factor pCREB in the nucleus accumbens. Administration of the β-adrenoreceptor blocker propranolol, which putatively attenuates this increase in pCREB, ameliorates the compulsive-like task engagement. Ultimately, gambling is a heterogeneous disorder that is unlikely to have a single underlying aetiology. However, these data indicate that aberrant dopaminergic signalling within the D2-like receptor family may underlie at least some of the cognitive perturbations observed in problem gambling.

description: In this lecture talk at the GCC 2020 we introduce SpaceLight a novel tool for similarity searching in very large chemical spaces. SpaceLight operates on combinatorial chemical spaces generated by applying chemical reactions to building blocks. The tool incorpates the substructure-driven molecular similarity description of topological fingerprints and retrieves results similar to that of well known fingerprint methods like ECFP. However, in contrast to existing approaches using fingerprints methods, SpaceLight employs a combinatorial search approach and thus is able to search chemical spaces containing 1015 compounds in seconds on a standard computer.

description: We compare multi-wavelength SFR indicators out to z~3 in GOODS-South. Our analysis uniquely combines U-to-8um photometry from FIREWORKS, MIPS 24um and PACS 70, 100, and 160um photometry from the PEP survey, and Ha spectroscopy from the SINS survey. We describe a set of conversions that lead to a continuity across SFR indicators. A luminosity-independent conversion from 24um to total infrared luminosity yields estimates of LIR that are in the median consistent with the LIR derived from PACS photometry, albeit with significant scatter. Dust correction methods perform well at low to intermediate levels of star formation. They fail to recover the total amount of star formation in systems with large SFR_IR/SFR_UV ratios, typically occuring at the highest SFRs (SFR_UV+IR \gtrsim 100 Msun/yr) and redshifts (z \gtrsim 2.5) probed. Finally, we confirm that Ha-based SFRs at 1.5

description: Anne Elisabeth Sejtens Det intelligente kød – træk af en begrebshistorie fra Descartes til Merleau-Ponty.(Intelligent flesh Features of a history of concepts from Descartes to Merleau-Ponty). The aim of the article is to reconstruct a piece of primarily French history of concepts, which from René Descartes to Maurice Merleau-Ponty shows that the position of flesh in the theory of cognition has grown quite prominent. In contrast to existing research, which by far is specifically philosophical with focus on connections between Husserl and Merleau-Ponty the article seeks to include a notable inheritance from the history of ideas from French philosophers of the Enlightenment Era, not least Diderot, where the flesh is the object of an actual philosophical consideration.

Cultural Flesh – Social Metabolism
Creators: name: McDonald, James F.
Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2010

description: James F. McDonalds Cultural Flesh – Social Metabolism: The Corporal Nature of Collective Forms. The point of departure of the article is Wittgenstein´s stress on the semantic insecurity of the concept of philosophy, and this insecurity is transferred in the article to a contemporary concept of culture. Through an inclusion of Marshall McLuhan´s description of media as something organic, something metaphorically physical, which extends the body, a ‘prioric’ concept of culture is suggested in the article. It is based on the cultural extension of the human body, and the term refers to the cultural categories that one is automatically or deterministically born into. This can be extended further with the article´s collected cultural concept of ‘liberate cultures’, as when e.g. a German adopts a Jamaican or global Rasta identity.

Precise analytic treatment of Kerr and Kerr-(anti) de Sitter black holes as gravitational lenses

description: The null geodesic equations that describe motion of photons in Kerr spacetime are solved exactly in the presence of the cosmological constant $Λ$. The exact solution for the deflection angle for generic light orbits (i.e. non-polar, non-equatorial) is calculated in terms of the generalized hypergeometric functions of Appell and Lauricella. We then consider the more involved issue in which the black hole acts as a `gravitational lens'. The constructed Kerr black hole gravitational lens geometry consists of an observer and a source located far away and placed at arbitrary inclination with respect to the black hole's equatorial plane. The resulting lens equations are solved elegantly in terms of Appell-Lauricella hypergeometric functions and the Weierstrass elliptic function. We then, systematically, apply our closed form solutions for calculating the image and source positions of generic photon orbits that solve the lens equations and reach an observer located at various values of the polar angle for various values of the Kerr parameter and the first integrals of motion. In this framework, the magnification factors for generic orbits are calculated in closed analytic form for the first time. The exercise is repeated with the appropriate modifications for the case of a non-zero cosmological constant.

Possible Odd-Frequency Superconductivity in Strong-Coupling Electron-Phonon Systems

description: A possibility of the odd-frequency pairing in the strong-coupling electron-phonon systems is discussed. Using the Holstein-Hubbard model, we demonstrate that the anomalously soft Einstein mode with the frequency $ω_{\rm E}\llω_{c}$ ($ω_{c}$ is the order of the renormalized bandwidth) mediates the s-wave odd-frequency triplet pairing against the ordinary even-frequency singlet pairing. It is necessary for the emergence of the odd-frequency pairing that the pairing interaction is strongly retarded as well as the strong coupling, since the pairing interaction for the odd-frequency pairing is effective only in the diagonal scattering channel, $(ω_{n},-ω_{n})\to(ω_{n'},-ω_{n'})$ with $ω_{n'}=ω_{n}\gtrsim ω_{\rm E}$. Namely, the odd-frequency superconductivity is realized in the opposite limit of the original BCS theory. The Ginzburg-Landau analysis in the strong-coupling region shows that the specific-heat discontinuity and the slope of the temperature dependence of the superfluid density can be quite small as compared with the BCS values, depending on the ratio of the transition temperature $T_{c}$ and $ω_{c}$.

description: To be democratic, a society’s members should be endowed with capacities and dispositions to communicate and understand the diversity of each other’s experiences. Philosophical traditions have explored various forms of injustice arising in societies failing to meet this democratic criterion, including material and psychological harm. But when exploring methods for cultivating and enhancing such democratic-communicative behavior, cognitive processes and intellectual instruction can face documented obstacles such as defensiveness, motivated ignorance, and perceptual-interpretive bias. Art, by virtue of its dealing in aesthetic experience, possesses several unique capacities for facilitating communication between diverse people and encouraging understanding of each other’s lived experiences, while overcoming the limitations of exclusively or heavily cognitive approaches. This paper explains three cumulative capacities of aesthetic forms which make them indispensable instruments for cultivating dispositions of democratic communication, including the avoidance of explicit argumentation, the communication of experiential immediacy, and the transformation of pre-existing interpretive frameworks. In doing so, it argues that art plays a crucial function in democratic society.

description: Nekrasov's partition function is defined on a flat bundle of R^4 over S^1 called the Omega background. When the fibration is self-dual, the partition function is known to be equal to the topological string partition function, which computes scattering amplitudes of self-dual gravitons and graviphotons in type II superstring compactified on a Calabi-Yau manifold. We propose a generalization of this correspondence when the fibration is not necessarily self-dual.

description: We study the use of sampling for efficiently mining the top-K frequent itemsets of cardinality at most w. To this purpose, we define an approximation to the top-K frequent itemsets to be a family of itemsets which includes (resp., excludes) all very frequent (resp., very infrequent) itemsets, together with an estimate of these itemsets' frequencies with a bounded error. Our first result is an upper bound on the sample size which guarantees that the top-K frequent itemsets mined from a random sample of that size approximate the actual top-K frequent itemsets, with probability larger than a specified value. We show that the upper bound is asymptotically tight when w is constant. Our main algorithmic contribution is a progressive sampling approach, combined with suitable stopping conditions, which on appropriate inputs is able to extract approximate top-K frequent itemsets from samples whose sizes are smaller than the general upper bound. In order to test the stopping conditions, this approach maintains the frequency of all itemsets encountered, which is practical only for small w. However, we show how this problem can be mitigated by using a variation of Bloom filters. A number of experiments conducted on both synthetic and real bench- mark datasets show that using samples substantially smaller than the original dataset (i.e., of size defined by the upper bound or reached through the progressive sampling approach) enable to approximate the actual top-K frequent itemsets with accuracy much higher than what analytically proved.

Observation of transition from laminar plug to well-mixed flow of fibre suspensions in Hagen-Poiseuille flow
Creators: name: Nikbakht, Abbas
Publisher: name: University of British Columbia
Year: 2016

description: The focus of the present work is an experimental study of the transition to turbulent flow of papermaking fibres in a cylindrical pipe. The suspensions used in this study possess a yield stress. With this class of fluid the radial profile in fully developed slow flow is characterized by an unyielded or plug zone. With increasing flow rates the size of the plug diminishes. One of the open remaining questions with these suspensions is the role of the plug during transition. In this work we characterize the size of the plug using ultrasound Doppler velocimetry as a function of flowrate for dilute, i.e. less than 2% consistency papermaking suspensions in a 50mm diameter pipe. The plug size was determined through analysis of local spatial and temporal variations in velocity, strain-rate, and the fluctuating component of velocity. With these we were able to estimate the yield stress of the suspension through knowledge of the applied pressure gradient and find the yield stress to be in the range of 2-60 Pa, depending upon consistency, fibre type and manufacturing methodology. The yield stress measurements were benchmarked against measurement methodologies reported in the literature. During flow, we observe complex behavior with the plug in which we found that with increasing velocity the plug diminishes through a densification mechanism in response to increasing frictional pressure drop. At higher Re, it diminishes through an erosion type mechanism. We estimate the critical Reynolds number for the disappearance of the plug to be Rec 10⁵. In perhaps the most unique measurements in this work we find that drag reduction begins when rp/R < 0.8, even when dilute long chain polymers are added to the system. For papermaking fibres, drag reduction displays non-monotonic behavior with plug size.

description: Il recente libro di Daniela Brogi, Giovani. Vita e scrittura tra fascismo e dopoguerra è costituito da quattro capitoli, su opere e autori distinti e ben inseriti nella maglia che tiene l’insieme (una maglia che, va da sé, si srotola sotto i nostri occhi fin dal titolo contenutistico). Il primo capitolo è su Romano Bilenchi e si interroga sul significato che ha avuto per lo scrittore toscano e per la sua generazione l’adesione al fascismo («il tema di queste pagine è anche uno dei più scabrosi», scrive Brogi nell’Introduzione). La parola-chiave che torna con insistenza in queste pagine è l’aggettivo «indivisibile». Bilenchi, prima fascista, poi gappista e militante del Pci clandestino, teorizza e pratica l’«etica della vita indivisibile», di un’esperienza da guardare interamente senza celare il male o le cadute. Ed è una prospettiva che, senz’altro, colpisce chi come noi abita un’epoca - ci spiegano gli psicanalisti - che scorda i fallimenti e vive del culto della prestazione. Giovani, così, considera la parabola della vita di Bilenchi con il nodo del distacco dal fascismo, indagando contemporaneamente l’altra parabola, quella tratteggiata dai testi letterari dello scrittore toscano e soprattutto dai suoi personaggi, Pisto, Dino, Aldo, Marco e poi gli adolescenti di Conservatorio di Santa Teresa.

Two Agency Problems in Subcontracting Systems : The Case of Japan’s Content Industry
Creators: name: Torii, Akio
Publisher: name: Nordic Journal of Media Management
Year: 2020

description: This study explains why a closed vertical cooperation system in Japan works in its assembly industry but not in its content industry using the multitask agency and common agency theories. Both theories attribute this issue in the content industry to inefficiencies in the overall subcontracting system and the asymmetric distribution of benefits. Two characteristics of the content industry further aggravate this problem. First, quality attributes of products in the content industry are difficult to verify, and thus, there are discrepancies between the evaluations of prime contractors and the efforts of subcontractors, leading to a moral hazard type of inefficiency. The unverifiable quality is used as a pretext by prime contractors to ‘hold up’ subcontractors. Second, in cases where subcontractors are common agents serving multiple contractors and technologies are applicable to each contractor in common, an adverse selection type of inefficiency is intensified, and prime contractors tend to squeeze surplus from subcontractors. In fact, most content producers in Japan serve multiple contractors. Given that the literature is yet to thoroughly address these factors, the findings can offer key insights on the topic. They highlight the importance of recognizing the essential features of the abovementioned problems to vitalize Japan’s content industry.

description: The positive correlation between planet detection rate and host star iron abundance lends strong support to the core accretion theory of planet formation. However, iron is not the most significant mass contributor to the cores of giant planets. Since giant planet cores are thought to grow from silicate grains with icy mantles, the likelihood of gas giant formation should depend heavily on the oxygen and silicon abundance of the planet formation environment. Here we compare the silicon and oxygen abundances of a set of 76 planet hosts and a control sample of 80 metal-rich stars without any known giant planets. Our new, independent analysis was conducted using high resolution, high signal-to-noise data obtained at McDonald Observatory. Because we do not wish to simply reproduce the known planet-metallicity correlation, we have devised a statistical method for matching the underlying [Fe/H] distributions of our two sets of stars. We find a 99% probability that planet detection rate depends on the silicon abundance of the host star, over and above the observed planet-metallicity correlation. We do not detect any such correlation for oxygen. Our results would thus seem to suggest that grain nucleation, rather than subsequent icy mantle growth, is the important limiting factor in forming giant planets via core accretion. Based on our results and interpretation, we predict that planet detection should correlate with host star abundance for refractory elements responsible for grain nucleation and that no such trends should exist for the most abundant volatile elements responsible for icy mantle growth.

description: This paper sheds light on the distinctive nature of entrepreneurial-oriented behaviours in news media firms by: (1) reconsidering conceptualisations of exploitation and exploration in the industry in order to provide further clarity to Organisational Ambidexterity (OA) measures; (2) offering a multidimensional construct for success of innovations that combines both objective and perceptual measures to allow direct comparisons; (3) drawing on data from a longitudinal study into the decision making of news media executives worldwide that provides historical and industry contexts; and (4) testing whether there are significant differences between the OA priorities of leaders at firms that report successes versus those who report poor performances. The investigation draws on the statistical analysis of original data collected from 1438 individuals in 107 countries. Though the results are based on a large sample, there still are limitations to the research, since the sample was self-selected, and the analysis methodology cross-sectional. However, objectivity was ensured through rigorous quantitative analysis, based upon strict significance testing. This study provides alternative definitions of exploitation and exploration and tests the relationships between them and the performance of news media firms. In so doing, it answers both the specific appeal for greater clarity of OA measures, as well as calls to test and expand existing theory in various contexts, and to develop theory that is directly pertinent to media management science.

Crowdfunded Journalism and Social Entrepreneurship: An Examination of Narrative and Entrepreneur Legitimacy
Creators: name: Cha, Jiyoung
Publisher: name: Nordic Journal of Media Management
Year: 2020

description: Crowdfunding is widely used for journalism, whose primary purpose is to provide information that citizens need. Therefore, this study frames journalism crowdfunding as social entrepreneurship and investigates how the characteristics of narratives and entrepreneurs influence citizens’ financial support for journalism crowdfunding. An analysis of journalism crowdfunding campaigns reveals how social change aims, public interest, past and future narratives, entrepreneurs’ gender and their affiliation with mainstream news outlets predict funding for journalism crowdfunding projects. The results provide both theoretical and practical implications for the role of narratives in gaining financial resources and the potential of crowdfunded journalism as a tool for social change.

Year: 2020

description: Digital media technologies transform the ways in which entrepreneurs communicate, organize and strategize. Yet, how strategy work is practiced as a form of “mediated” engagement with audiences through social media technologies remains a novel ground. Therefore, this paper traces the growing interdisciplinary literature and describes (1) how media is playing a more predominant role in entrepreneurship, (2) how classical media entrepreneurship is opening up, and (3) how digital media entrepreneurship (DME) emerges. Subsequently, the paper envisions how DME can be seen as a strategic practice of entrepreneurs. We discuss implications for entrepreneurial strategy work regarding entrepreneurial identity development and entrepreneurial knowledge construction, with a particular emphasis on co-location. Overall, this contributes to our understanding of strategy work of beginning entrepreneurs and sheds light on possibilities for future research.

Ceserani e la scuola

description: Quando cominciò a uscire, alla fine degli anni settanta, Il materiale e l’immaginario (a cura di Ceserani e De Federicis, Loescher, Torino 1979-1988), ne parlai subito alla radio (tenevo una rubrica culturale su RAI 3). Non fui l’unico. Ne discussero poi, negli anni successivi, diversi altri studiosi: ricordo, fra gli altri, Giovannetti su Tirature, Fortini sul Corriere della sera, Zinato su Allegoria. Il dibattito culturale, insomma, non si era ancora del tutto estinto. E, d’altra parte, ciò che colpiva, nella operazione di Ceserani e De Federicis, era appunto la dimensione culturale alta, insolita nei manuali di letteratura. I due autori avevano non solo un disegno didattico, ma un progetto culturale nuovo e ambizioso. I manuali non erano ancora diventati un mero prodotto della cucina redazionale degli editori, in cui lo studioso di turno appone la propria firma, come accadrà sempre più spesso negli ultimi dieci-dodici anni, ma potevano essere il banco di prova di un metodo e addirittura, come nel caso in questione, di una nuova ipotesi interpretativa della storia.

description: This paper presents a finding of the correlation between the width of a strong diffuse interstellar band at 6196A and the excitation temperature of C2 based on high resolution and high signal-to-noise ratio spectra. The excitation temperature was determined from absorption lines of the Phillips A-X and Mulliken D-X systems. The width and shape of the narrow 6196A DIB profile apparently depend on the C2 temperature, being broader for higher values.

description: An analytical solution for the discrepancy between observed core-like profiles and predicted cusp profiles in dark matter halos is studied. We calculate the distribution function for Navarro-Frenk-White halos and extract energy from the distribution, taking into account the effects of baryonic physics processes. We show with a simple argument that we can reproduce the evolution of a cusp to a flat density profile by a decrease of the initial potential energy.

description: Già dalla discussione che si sta sviluppando su questa rivista intorno al libro di Antonello credo si veda bene una contrapposizione che mi capita spesso di rilevare nel dibattito nostrano: da un lato la sacrosanta irritazione verso un certo conservatorismo di sinistra e verso la lamentosa condanna “crisologica” della contemporaneità, atteggiamenti tanto diffusi quanto sterili; dall’altro una condivisibile preoccupazione: non diventeremo, per dirla con Milan Kundera, gli «allegri alleati dei nostri stessi becchini»? Nell’affrancarci da posizioni che sembrano obsolete, cosa ci rimane da contrapporre al dominio dell’ideologia mercantile e brutalmente quantitativa del neoliberismo?

Geochemical mapping of porphyry deposits and associated alteration through transported overburden
Creators: name: Rich, Shane Daniel
Publisher: name: University of British Columbia

description: Discoveries of porphyry copper deposits (PCDs) in British Columbia have declined over the past 20 years. Undiscovered PCDs are predicted to occur in the Intermontane Belt, an assemblage of volcanic arc terranes considered important for hosting large porphyry deposits. The Deerhorn Cu-Au porphyry, located within this belt, is covered with up to 60 m of undisturbed moraine. Detailed regolith mapping based on a new classification scheme for BC, combined with aqua regia and deionised water assays, sequential leaching, physicochemical measurements and hydrocarbon analysis, was undertaken to determine the response in the till to buried mineralisation. Geochemical relationships dependent on the regolith type were identified and are particularly evident in organic rich areas. To minimise background noise, data analysis was constrained to the dominent regolith unit: the undisturbed moraine (DrM), resulting in enhanced anomaly identification. Regolith mapping in advance of a soil survey can therefore allow targeted efficient sampling. Normalisation to organic carbon (Corg) to counteract the influence of organic matter on trace element variability resulted in anomalous response for elements As, Cs, Cu, Mo, Tl, U and W by conventional aqua regia on a 180-micron fraction B-upper-horizon soil. The response for six of these elements is peripheral to mineralisation in the surface environment. Multi-element evaluation is superior for mineralisation detection than individual element evaluation. Light hydrocarbon results indicate a surface response with a distinct depletion over mineralisation. Sequential leaching on selected anomalous Cu samples indicates that an aqua regia extraction was the optimal first choice for anomalous Cu detection. Copper-Fe-oxide-bearing grains interpreted as oxidised sulphides were recovered from an anomalous Cu-bearing sample and confirm a contribution of glacial clastic transport. Visual screening for clastic fragments allows a reprioritisation of anomalous response. Copper isotope results do not support Cu-ion migration from the buried mineralisation, but instead support a clastic contribution. Anomaly formation is interpreted as a combination of clastic transport, ionic migration of H⁺, vegetation uptake and surface redistribution.
Political Economy of Media Entrepreneurship: Power, Control and Ideology in a News Media Enterprise

description: With digital technologies crushing entry barriers, India is witnessing a new wave of digital news media entrepreneurship. Many of these news start-ups, set up by former journalists, want to challenge the corporate control of media by adopting new revenue models that do not depend on advertising. However, very little research exists on news media entrepreneurship in India. Using the case study of an ad-less digital news media start-up, this study explores the objectives of news media entrepreneurship and the role of technology in creating an independent space for democratic interactions. Analyses of the interview and textual data reveal that news media entrepreneurship is an ideological process and that digital technologies do not always create and sustain democratic interactive space for news. The study shows that the government and corporates control the Internet and social media and a media organization that is totally dependent on these technologies for news distribution faces protracted legal battles and possible censorship.
