description: In this paper, a wireless cooperative network is considered, in which multiple source-destination pairs communicate with each other via an energy harvesting relay. The focus of this paper is on the relay's strategies to distribute the harvested energy among the multiple users and their impact on the system performance. Specifically, a non-cooperative strategy is to use the energy harvested from the i-th source as the relay transmission power to the i-th destination, to which asymptotic results show that its outage performance decays as logSNR over SNR. A faster decaying rate, 1 over SNR, can be achieved by the two centralized strategies proposed this the paper, where the water filling based one can achieve optimal performance with respect to several criteria, with a price of high complexity. An auction based power allocation scheme is also proposed to achieve a better tradeoff between the system performance and complexity. Simulation results are provided to confirm the accuracy of the developed analytical results and facilitate a better performance comparison.

description: Placing a sensor close to the target at the nano-level is a central challenge in quantum sensing. We demonstrate high-spatial-resolution magnetic field imaging with a boron vacancy (V$_\text{B}^-$) defects array in hexagonal boron nitride with a few 10 nm thickness. V$_\text{B}^-$ sensor spots with a size of (100 nm)$^2$ are arranged periodically with nanoscale precision using a helium ion microscope and attached tightly to a gold wire. The sensor array allows us to visualize the magnetic field induced by the current in the wire with a spatial resolution beyond the diffraction limit. Each sensor exhibits a practical sensitivity of $73.6~μ\text{T/Hz}^{0.5}$, suitable for quantum materials research. Our technique of arranging V$_\text{B}^-$ quantum sensors periodically and tightly on measurement targets will maximize their potential.

description: The evolution of jaws in cichlid fishes of the East African Great Lakes is a textbook example of adaptive radiation in vertebrates. Karl Liem postulated that this adaptive radiation has been possible due to the functional decoupling of two cichlid functional units – the pharyngeal jaw (PJ) and the oral jaw (OJ). This functional decoupling of the jaws has enabled the OJ to be relieved of its dual role of prey capturing and processing and has allowed the PJ to take on the role of prey processing. As a result, African cichlids have adapted the morphology of their functional units (i.e., oral jaws) to specialize in a feeding mechanism best suited for their habitat. However, global morphological changes (across the OJ and PJ) are understudied, especially, at the genetic level.
In this study, two rock dwelling species of African Cichlids from Lake Malawi were used - Labeotropheus fuelleborni (LF) and Tropheops “red cheek” (TRC). Both species have distinct craniofacial morphologies for specialized benthic feeding (LF) and for generalized feeding (TRC). This morphological variation allowed us to investigate the functional decoupling of the jaws by studying differences in bone shape and muscle volumes in an F5 hybrid population. Strong phenotypic correlations were observed between and within the tissues of the OJ and PJ. Further, to identify phenotype to genotype associations, a Quantitative Locus (QTL) analysis and a fine mapping analysis was conducted. The results show some evidence of overlapping genetic control (i.e., pleiotropy) suggesting some genetic coupling between the two jaws.

description: The nature of dark matter (DM) remains one of the unsolved mysteries of modern physics. An intriguing possibility is to assume that DM consists of ultralight bosonic particles in the Bose-Einstein condensate (BEC) state. We study stationary DM structures by using the system of the Gross-Pitaevskii and Poisson equations, including the effective temperature effect with parameters chosen to describe the Milky Way galaxy. We have investigated DM structure with BEC core and isothermal envelope. We compare the spherically symmetric and vortex core states, which allows us to analyze the impact of the core vorticity on the halo density, velocity distribution, and, therefore, its gravitational field. Gravitational field calculation is done in the gravitoelectromagnetism approach to include the impact of the core rotation, which induces a gravimagnetic field. As result, the halo with a vortex core is characterized by smaller orbital velocity in the galactic disk region in comparison with the non-rotating halo. It is found that the core vorticity produces gravimagnetic perturbation of celestial body dynamics, which can modify the circular trajectories.

description: Analysing the news mentions of the 150 most cited scholars researching artificial intelligence in the UK and US, this factsheet offers three main findings. First, news mentions are concentrated on a small number of high-profile scholars. Second, scholars with industry affiliations are far more likely to be mentioned in news and to attract more news attention. Third, many of the scholars who feature most frequently in the news are men. Interviews with AI researchers and UK-based technology journalists reveal the influence of industry public relations efforts. Interviews also demonstrate that as journalists face pressure to produce popular stories on tight deadlines, they have an incentive to rely on industry sources who can offer ready-made stories and timely insight. However, increasing the diversity of sources and story subjects could help provide broader, richer, and potentially more critical insight into the many pressing public problems and opportunities surrounding artificial intelligence.

description: In this RISJ Factsheet, we analyse eight months of reporting on artificial intelligence (AI) in six mainstream news outlets in the United Kingdom to understand how AI is emerging as a public issue. Our mixed-methods analysis reveals that a majority of articles are pegged to industry concerns, and a plurality of sources originate from industry. Coverage frequently amplifies self-interested assertions of AI’s value and potential, while positioning AI primarily as a private commercial concern and undercutting the role of public action in addressing AI. Portraying AI as a relevant and competent solution to a range of public problems, outlets also regularly assert the influence it will have across areas of public life often with little acknowledgement of ongoing debates concerning AI’s potential effects. Finally, AI is being politicised through the topics that outlets emphasise: right-leaning outlets highlight issues of economics and geopolitics and left-leaning outlets highlight issues of ethics and discrimination.

description: More than three years after the United Kingdom narrowly voted to leave the European Union, journalists, academics and politicians still debate the role the news media played during the referendum campaign. People wonder whether new forms of online communication swung the result, whether people’s understanding of the EU has been shaped by decades of partisan coverage, and whether parts of the news media are structurally biased towards a particular worldview. In this factsheet we have compared the current media habits of those who voted to remain with those who voted to leave. Our findings challenge some widely-held assumptions. Both leave and remain voters mainly access news offline via print, television and radio. Remainers are more likely to use the Guardian, the Times, the Mirror and HuffPost for news. Leavers are more likely to access news from the Sun, the Daily Mail, Sky and ITV. However, the most popular outlet with both groups by far is BBC News. And if we focus on newspapers with a clear position on Brexit, only a tiny proportion of leavers (3%) and remainers (1%) get all of their news from either a pro-leave or pro-remain outlet. Finally, there is little difference in social media news use between leavers and remainers, with the exception that those who voted remain are more likely to use Twitter. These insights come from the 2019 Reuters Institute Digital News Report (Newman et al. 2019). The report is based on an online survey of news users carried out by YouGov in 38 markets, including the UK, in February 2019.

description: Orbital-lattice coupled excitation dynamics in orbitally degenerate correlated systems are examined. We present a theoretical framework, where both local vibronic excitations and superexchange-type inter-site interactions are dealt with on an equal footing. We generalize the spin-wave approximation so as to take local vibronic states into account. Present method is valid from weak to strong Jahn-Teller coupling magnitudes. Two characteristic excitation modes coexist; a low-energy dispersive mode and high-energy multi-peak mode. These are identified as a collective vibronic mode, and Flanck-Condon excitations in a single Jahn-Teller center modified by the inter-site interactions, respectively. Present formalism covers vibronic dynamics in several orbital-lattice coupled systems.

description: Reduced graphene oxide (rGO) is a bulk-processable quasi-amorphous 2D material with broad spectral coverage and fast electronic response. rGO sheets are suspended in a polymer matrix and sequentially photoreduced while measuring the evolving optical spectra and ultrafast electron relaxation dynamics. Photoreduced rGO yields optical absorption spectra that fit with the same Fano lineshape parameters as monolayer graphene. With increasing photoreduction time, rGO transient absorption kinetics accelerate monotonically, reaching an optimal point that matches the hot electron cooling in graphene. All stages of rGO ultrafast kinetics are simulated with a hot-electron cooling model mediated by disorder-assisted supercollisions. While the rGO room temperature 0.31 ps$^{-1}$ electronic cooling rate matches monolayer graphene, subsequent photoreduction can rapidly increase the rate by ~10-12$\times$. Such accelerated supercollision rates imply a reduced mean-free scattering length caused by photoionized point-defects on the rGO sp$^2$ sub-lattice. For visible range excitations of rGO, photoreduction shows three increasing spectral peaks that match graphene quantum dot (GQD) transitions, while a broad peak from oxygenated defect edge states shrinks. These three confined GQD states donate their hot carriers to the graphene sub-lattice with a 0.17 ps rise-time that accelerates with photoreduction. Collectively, many desirable photophysical properties of 2D graphene are replicated through selectively reducing rGO scaffolded within a 3D bulk polymeric network.

Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.

On Noisy ARQ in Block-Fading Channels

description: Assuming noisy feedback channels, this paper investigates the data transmission efficiency and robustness of different automatic repeat request (ARQ) schemes using adaptive power allocation. Considering different block-fading channel assumptions, the long-term throughput, the delay-limited throughput, the outage probability and the feedback load of different ARQ protocols are studied. A closed-form expression for the power-limited throughput optimization problem is obtained which is valid for different ARQ protocols and feedback channel conditions. Furthermore, the paper presents numerical investigations on the robustness of different ARQ protocols to feedback errors. It is shown that many analytical assertions about the ARQ protocols are valid both when the channel remains fixed during all retransmission rounds and when it changes in each round (in)dependently. As demonstrated, optimal power allocation is crucial for the performance of noisy ARQ schemes when the goal is to minimize the outage probability.

description: Decays of B mesons into final states containing a tau lepton are sensitive to new charged-current interactions that break lepton-flavor universality. These decays have been studied only at e+e- colliders, where the low-background environment and well-known initial state make it possible to observe small signals with undetectable neutrinos. In particular, the large data samples of the B factories and recent advances in techniques for full-event reconstruction have led to evidence for the decay B --> tau nu and unambiguous observation of the decays B --> D(*)tau nu. These results have led to exclusion of large regions of the parameter space for a variety of new-physics models. Furthermore, the branching fraction for B --> D(*)tau nu has been measured to be higher than the standard-model expectation by at least 3.4 standard deviations, making this an interesting topic for further research. This letter reviews the theoterical and experimental status of this topic, summarizing the results at this time and outlining the path for further improvements.

Plugging into the Body of the Leviathan: Proposal for a New Sociology of Public Interventions
Creators: name: Eyal, Gil
Publisher: name: Columbia University
Year: 2013
Subjects: subject: Sociology
subject: FOS: Sociology

description: The main argument of this short essay is that the concept of intellectual, especially the somewhat redundant neologism of public intellectual, is too narrow to guide research on how interventions in public affairs are currently authored, crafted, and operated. Instead, I propose the concept of public interventions to inform a more comprehensive approach that broadens the analytical frame by multiplying relevant agencies, modes and targets of intervention. This approach is inspired by Foucault’s (2000) distinction between the “universal” and “specific” intellectual; Bourdieu’s (Corporatism) replacement of the latter by a “collective intellectual”; and the approach to the public sphere urged by the contributors to Making Things Public (Latour and Weibel).
For a Sociology of Expertise: The Social Origins of the Autism Epidemic

Publisher: name: Columbia University

Subjects: subject: Sociology
subject: FOS: Sociology

description: This article endeavors to replace the sociology of professions with the more comprehensive and timely sociology of expertise. It suggests that we need to distinguish between experts and expertise as requiring two distinct modes of analysis that are not reducible to one another. It analyzes expertise as a network linking together agents, devices, concepts, and institutional and spatial arrangements. It also suggests rethinking how abstraction and power were analyzed in the sociology of professions. The utility of this approach is demonstrated by using it to explain the recent precipitous rise in autism diagnoses. This article shows that autism remained a rare disorder until the deinstitutionalization of mental retardation created a new institutional matrix within which a new set of actors -- the parents of children with autism in alliance with psychologists and therapists -- were able to forge an alternative network of expertise.
title: Fabrication of Binder-Free Electrodes Based on Graphene Oxide with CNT for Decrease of Resistance
Creators: name: Zhang, Di
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: In electrode double layer capacitor (EDLC), electrodes usually contain binder materials to provide adhesion between electrode materials. However, binder materials usually bring unwanted resistances to the component due to their non-conductivity properties and the occupation of ion cavities. The purpose of this thesis is to demonstrate the feasibility of fabricating electrodes for EDLCs by using carbon nanotubes (CNTs) and graphene oxide (GO) without using any binding materials. At the same time, investigating the binder-free electrode’s electrochemical properties and make an assumption of its potential application in the future.
The slurry of binder-free electrodes was fabricated by ultrasonicating water suspended CNTs and GO aqueous solution. The ultrasonicated mixture was then casted on an aluminum foil, followed by drying processes to form into an electrode film. By combining the CNTs/GO binder-free electrodes with aqueous electrolyte, a symmetrical electrode double layer capacitor (EDLC) was fabricated. The EDLC was also tested for electrochemical performance using a polyvinyl alcohol (PVA) based gel electrolyte. It was found that an electrode with a low resistance was achieved by eliminating the use of binders. The as-prepared sample had an equivalent series resistance (ESR) of 0.07 Ohms. Furthermore, a solid-state, binder-free EDLC sample achieved a specific capacitance of 0.2876 F/m2 in volumetric terms, or 58.24 mF/g in gravimetric terms.
The laboratorial investigation demonstrates a possible scheme of decreasing resistance start with eliminating binding materials in electrodes. Successfully fabricated binder-free electrodes show the feasibility of eliminating binding materials in electrodes. The easy access fabrication process of graphene oxide/CNT electrodes provides a chance for mass production in the industry. Solid-state electrolyte samples also give an example of making all-solid-state energy storage devices.

description: We discuss the global scattering response of invisibility cloaks over the entire frequency spectrum, from static to very high frequencies. Based on linearity, causality and energy conservation we show that the total extinction and scattering, integrated over all wavelengths, of any linear, passive, causal and non-diamagnetic cloak necessarily increases compared to the uncloaked case. In light of this general principle, we provide a quantitative measure to compare the global performance of different cloaking techniques and we discuss solutions to minimize the global scattering signature of an object using thin, superconducting shells. Our results provide important physical insights on how invisibility cloaks operate and affect the global scattering of an object, suggesting ways to defeat countermeasures aimed at detecting cloaked objects using short impinging pulses.

Building local stellar spectra from observations: the neutral helium chromospheric lines

description: The EVaporating Exoplanets (EVE) code allows to model an escaping atmosphere on a transiting exoplanet in three dimensions. With EVE we are then able to make predictions on the signatures caused by the absorbing atmosphere, in the observed transmitted stellar spectrum. A key ingredient in our model is the local synthetic stellar spectrum that we use to construct the total flux emitted by the star. The synthetic spectrum has to be as faithful as possible to the actual observed stellar spectrum. Indeed, the knowledge of the local stellar spectrum allows to identify, at each instant of the transit, the actual part of the stellar flux that is hidden and absorbed by the planet. Thus, giving the possibility to generate realistic absorption signatures comparable to observations. In this work we show how we model the local stellar spectrum for the helium triplet lines at 1083nm, directly based on the observed stellar flux. These chromospheric lines are of interest for transit observations, as helium is easily found at high altitudes in planetary atmosphere. Additionally, the conditions for the formation of the metastable helium triplet are met around young stars which radiate higher levels of extreme UV flux.

Eastern Europe as a Laboratory for Economic Knowledge: The Transnational Roots of Neoliberalism

description: Using Latour’s concepts of “actor-network” and “translation,” the authors show that neoliberalism’s success in Eastern Europe is best analyzed not as an institutional form diffused along the nodes of a network, but as itself an actor-network based on a particular translation strategy that construes socialism as a laboratory of economic knowledge. They argue that socialism was made into a laboratory of economic knowledge during the socialist calculation debate of the 1920s and 1930s. An extensive debate during the Cold War is also documented and shows that a transnational network continued to be organized around attempts to connect the results obtained in the socialist laboratory with debates and struggles in Western economics. Finally, the drafting of transition blueprints in postcommunist Eastern Europe after 1989, with the participation of American economists, is shown to be a continuation of this transnational network.

By considering an cold electronic plasma in a long pipe, the Maxwell equations in 3+1 formalism will be invoked to relate gravitational waves to the perturbations of plasma particles. It will be shown that the impact of GW on cold electronic plasma causes disturbances on the paths of the electrons. Those electrons that absorb energy from GW will pass through the potential barrier at the end of the pipe. Therefore, crossing of some electrons over the barrier will imply the existence of the GW.

description: Two-dimensional (2D) materials exhibit a wide range of remarkable phenomena, many of which owe their existence to the relativistic spin-orbit coupling (SOC) effects. To understand and predict properties of materials containing heavy elements, such as the transition-metal dichalcogenides (TMDs), relativistic effects must be taken into account in first-principles calculations. We present an all-electron method based on the four-component Dirac Hamiltonian and Gaussian-type orbitals (GTOs) that overcomes complications associated with linear dependencies and ill-conditioned matrices that arise when diffuse functions are included in the basis. Until now, there has been no systematic study of the convergence of GTO basis sets for periodic solids either at the nonrelativistic or the relativistic level. Here we provide such a study of relativistic band structures of the 2D TMDs in the hexagonal (2H), tetragonal (1T), and distorted tetragonal (1T') structures, along with a discussion of their SOC-driven properties (Rashba splitting and $\mathbb{Z}_2$ topological invariants). We demonstrate the viability of our approach even when large basis sets with multiple basis functions involving various valence orbitals (denoted triple- and quadruple-$ζ$) are used in the relativistic regime. Our method does not require the use of pseudopotentials and provides access to all electronic states within the same framework. Our study paves the way for direct studies of material properties, such as the parameters in spin Hamiltonians, that depend heavily on the electron density near atomic nuclei where relativistic and SOC effects are the strongest.

description: The ubiquity of electronics in modern technology is undeniable. Although it is not feasible to design or analyze circuits in an exhaustively detailed fashion, it is still imperative that circuit design engineers understand the pertinent physical tradeoffs and are able to think at the appropriate level of mathematical abstraction. This thesis presents several mathematical modeling techniques of common electronic systems.

First, we derive, ab initio, a general analytical model for the behavior of electrical oscillators under injection without making any assumptions about the type of oscillator or the size or shape of the injection. This model provides novel insights into the phenomena of injection locking and pulling while subsuming existing theories found in the literature.  Next, we focus on the familiar scenario of an inductor-capacitor (LC) oscillator locked to a sinusoidal signal. An exact analysis of this circuit is carried out for an arbitrary injection strength and frequency, a task which has not been executed to fruition in the existing literature. This analysis intuitively illuminates the fundamental physics underlying the synchronization of electrical harmonic oscillators, and it generalizes the notion of the lock range for such oscillators into separate necessary and sufficient conditions. We then turn to the classical estimate of the bandwidth of a linear time-invariant (LTI) system via the sum of its zero-value time constants (ZVTs), and we show that this sum can actually be used to tightly bound the bandwidth—both from above and from below—in addition to simply estimating it. Finally, we look at a natural generalization of the Gilbert cell topology: an analog multiplier for an arbitrary number of inputs; we then analyze its large- and small-signal characteristics as well as its frequency response.

Throughout, we will demonstrate how infusing physical intuition with mathematical rigor whilst seeking a balance between detailed analysis and abstract modularity results in models that are conceptually insightful, sufficiently accurate, and computationally feasible.

description: Michael Burawoy offers three thought-provoking criticisms of our book, Making Capitalism without Capitalists: Class Formation and Elite Struggles in Post-Communist Central Europe: (1) that we abandon class analysis, (2) that we do not suggest an alternative to the present capitalist order, and, therefore, (3) that our “neoclassical sociology” abandons the critical vision of classical sociology. At this abstract level, we plead not guilty to all three charges. Moving beyond these abstractions, we reformulate Burawoy’s criticisms empirically, and ask the following questions: 1. Is interclass struggle the central cause of social change in the transformation from communism to capitalism? 2. Using social scientific tools, can we identify a noncapitalist (or to be less shy about it, a socialist) alternative to the “actually existing” socioeconomic systems of the postcommunist world? 3. Is it necessary to have a vantage point “outside” a system to critically analyze its mechanisms and dynamics? Burawoy answers these questions in the affirmative; our answer to each is an emphatic no.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.
The atmospheric circulation of the super Earth GJ 1214b: Dependence on composition and metallicity

description: We present three-dimensional atmospheric circulation models of GJ 1214b, a 2.7 Earth-radius, 6.5 Earth-mass super Earth detected by the MEarth survey. Here we explore the planet's circulation as a function of atmospheric metallicity and atmospheric composition, modeling atmospheres with a low mean-molecular weight (i.e., H2-dominated) and a high mean-molecular weight (i.e. water- and CO2-dominated). We find that atmospheres with a low mean-molecular weight have strong day-night temperature variations at pressures above the infrared photosphere that lead to equatorial superrotation. For these atmospheres, the enhancement of atmospheric opacities with increasing metallicity lead to shallower atmospheric heating, larger day-night temperature variations and hence stronger superrotation. In comparison, atmospheres with a high mean-molecular weight have larger day-night and equator-to-pole temperature variations than low mean-molecular weight atmospheres, but differences in opacity structure and energy budget lead to differences in jet structure. The circulation of a water-dominated atmosphere is dominated by equatorial superrotation, while the circulation of a CO2-dominated atmosphere is instead dominated by high-latitude jets. By comparing emergent flux spectra and lightcurves for 50x solar and water-dominated compositions, we show that observations in emission can break the degeneracy in determining the atmospheric composition of GJ 1214b. The variation in opacity with wavelength for the water-dominated atmosphere leads to large phase variations within water bands and small phase variations outside of water bands. The 50x solar atmosphere, however, yields small variations within water bands and large phase variations at other characteristic wavelengths. These observations would be much less sensitive to clouds, condensates, and hazes than transit observations.

Music and Jugendstil
Creators: name: Frisch, Walter M.
Publisher: name: Columbia University
Year: 1988
Subjects: Music

description: There is at present a large body of writings specifically about the relationship between music and Jugendstil and/or art nouveau. It is here that some of the most ambitiously interdisciplinary musical criticism and analysis have been focused -- interdisciplinary in spirit, but often undisciplined in practice. Even in the most suggestive of this work, music tends to remain undernourished -- sometimes abused -- perhaps because its basic language and "meaning" are notoriously difficult to decipher, let alone relate convincingly to some broader zeitgeist. And yet the essential enterprise seems worthwhile: most historians and critics of the arts would agree that music does, or should, partake of the artistic climate of its time in ways that are demonstrable and meaningful. The years around 1900, which saw many sustained contacts and associations between artists working in different media, seem a logical place to look. But to be convincing, parallels involving music must rise above (or get below) the feuilletonish level encountered in so many writings. They should also take account of more than the purely literary dimension of the music (opera librettos, song texts, programmatic commentaries, and so forth) and be made at a fundamental level of technique and expression that does justice to musical processes. The present article is conceived in that spirit, suggesting how deeper connections might be drawn between the phenomenon of Jugendstil, which was itself largely inspired by the idea of music, and some of the best Austro-German lieder of the Jahrhundertwende, especially those of Arnold Schoenberg.

description: The last decade has seen rising interest in developing ways to measure the impacts of investigative journalism. This factsheet offers a comparative analysis of outcomes of the 'Panama Papers’ investigation of 2016, which ultimately involved more than 500 reporters working in more than 80 countries. With a content analysis of impacts self-reported by journalists over three years, we show that ‘deliberative’ outcomes indicating official discussion or investigation have been the most common impact, evident in 45 percent of jurisdictions tracked; we find evidence of ‘individualistic’ outcomes involving accountability for specific people or companies in a third, and of 'substantive’ legal or policy change in 18 percent. We also evidence of backlash against reporters nearly as often as substantive reforms, though rarely in the same countries. Our analysis shows that major investigative reports may continue to have significant impacts years after publication, and that substantive reforms require time to take shape.
Superbroad Component in Emission Lines of SS 433

description: We have detected new components in stationary emission lines of SS 433; these are the superbroad components that are low-contrast substrates with a width of 2000--2500 km s-1 in He I $\lambda4922$ and H$β$ and 4000--5000 km s-1 in He II $\lambda4686$. Based on 44 spectra taken during four years of observations from 2003 to 2007, we have found that these components in the He II and He I lines are eclipsed by the donor star; their behavior with precessional and orbital phases is regular and similar to the behavior of the optical brightness of SS 433. The same component in H$β$ shows neither eclipses nor precessional variability. We conclude that the superbroad components in the helium and hydrogen lines are different in origin. Electron scattering is shown to reproduce well the superbroad component of H$β$ at a gas temperature of 20--35 kK and an optical depth for Thomson scattering $τ\approx$ 0.25--0.35. The superbroad components of the helium lines are probably formed in the wind from the supercritical accretion disk. We have computed a wind model based on the concept of Shakura-Sunyaev supercritical disk accretion. The main patterns of the He II line profiles are well reproduced in this model: not only the appearance of the superbroad component but also the evolution of the central two-component part of the profile of this line during its eclipse by the donor star can be explained.
