description: Η πανδημία Covid-19 αποτέλεσε και εξακολουθεί να αποτελεί γεγονός – σταθμό στη σύγχρονη πραγματικότητα. Έρχεται να προστεθεί στον ιστορικό χάρτη προγενέστερων, εξαιρετικά σημαντικών, πανδημιών που στιγμάτισαν και καθορίσαν την εξελικτική πορεία του ανθρωπίνου είδους. Η βαρύνουσα σημασία της εν λόγω πανδημίας είναι ανάλογη των σοβαρών επιπτώσεων που έχει επιφέρει σε όλους σχεδόν τους τομείς της ανθρώπινης πραγματικότητας. Επιδρά καθοριστικά και καίρια στη δομή της κοινωνίας, στην οικονομία, στην υγεία, στον τρόπο λειτουργιάς του κράτους και στις ανθρώπινες σχέσεις. Κατ΄επέκταση, ο ισχυρός αυτός αντίκτυπος της πανδημίας Covid-19 στη ζωή του ανθρώπου καθιστά σαφέστατη και αναμενομένη την έμμεση και άμεση, επίδρασή της στην ψυχική υγεία του γενικού πληθυσμού. Τα ψυχικά προβλήματα που ανακύπτουν από τη δυσκολία διαχείρισης των κοινωνικών περιορισμών που η πανδημία επιβάλλει, έρχονται με δριμύ τρόπο στο προσκήνιο και επιτάσσουν την εύρεση αμέσων και αποτελεσματικών τρόπων για την αντιμετώπισή τους.
description: The Covid-19 pandemic was, and continues to be, an event - a milestone in modern reality. It is added to the historical map of previous, extremely important, pandemics that marked and determined the evolutionary course of the human species. The significant importance of this pandemic is commensurate with the serious effects it has brought about in almost all areas of human reality. It has a decisive and crucial effect on the structure of society, the economy, health, the way the state functions and human relations. Therefore, the strong impact of the Covid-19 pandemic on human life makes its, indirect and direct, effect on the mental health of the general population, clear and expected. The mental problems that arise from the difficulty of managing the social restrictions that the pandemic imposes, come to the fore in a harsh way and require the finding of immediate and effective ways to deal with them.

description: The moon phase affects the ecology and vocal activity of nightjars (Caprimulgidae). However, some studies have found contradictory results regarding the impact of the moon phase on the vocal activity of nightjars. To increase our knowledge on this topic, we monitored the vocal behavior of two Neotropical nigthjars, the Little nightjar (Setopagis parvula) and the Common pauraque (Nyctidromus albicollis), over 5 lunar cycles in the Brazilian Pantanal. We tested the relationships between the moon phase and daily vocal output (number of calls uttered) and the proportions of calling activity at dusk, midnight, and dawn. Our results suggest that moonlight stimulated the vocal output of both species, since it was between 6 and 8 times higher during full moon nights than during new moon nights. Likewise, the proportion of calling activity at midnight was significantly higher during full moon nights. In contrast, the proportion of calling activity of both species was higher at dawn during new moon nights than under the full moon. The calling activity of the Common pauraque was also higher at dusk during new moon nights. These findings might be partly related to the much lower vocal output at midnight during full moon nights and therefore higher proportions of vocal activity at dusk and at dawn under new moon scenarios. This is the first study comparing the vocal behavior of two Neotropical nightjars over different moon phases and shows that the impact of moonlight may differ between species and at a daily scale when analyzing the periods with the highest and lowest illumination. The consequences of the increase in vocal output under moonlight are unknown and should be assessed.

description: We study the stability properties of hydrodynamic shocks with finite Mach numbers. The linear analysis supplements previous analyses which took the strong shock limit. We derive the linearised equations for a general specific heat ratio as well as temperature and density power-law cooling functions, corresponding to a range of conditions relevant to interstellar atomic and molecular cooling processes. Boundary conditions corresponding to a return to the upstream temperature ($R$ = 1) and to a cold wall ($R$ = 0) are investigated. We find that for Mach number $M > 5$, the strong shock overstability limits are not significantly modified. For $M < 3$, however, shocks are considerably more stable for most cases. In general, as the shock weakens, the critical values of the temperature power-law index (below which shocks are overstable) are reduced for the overtones more than for the fundamental, which signifies a change in basic behaviour. In the $R$ = 0 scenario, however, we find that the overstability regime and growth rate of the fundamental mode are increased when cooling is under local thermodynamic equilibrium. We provide a possible explanation for the results in terms of a stabilising influence provided downstream but a destabilising effect associated with the shock front. We conclude that the regime of overstability for interstellar atomic shocks is well represented by the strong shock limit unless the upstream gas is hot. Although molecular shocks can be overstable to overtones, the magnetic field provides a significant stabilising influence.

description: This paper first establishes a new core theorem using the concept of generated payoffs: the TU (transferable utility) core is empty if and only if the maximum of generated payoffs (mgp) is greater than the grand coalition’s payoff v(N), or if and only if it is irrational to split v(N). It then provides answers to the questions of what payoffs to split, how to split the payoff, what coalitions to form, and how long each of the coalitions will be formed by rational players in coalitional TU games. Finally, it obtains analogous results in coalitional NTU (non-transferable utility) games.

description: It was long assumed that only humans can distinguish the living from the dead. Renewed interest in this question over the last decade has led several authors to assert that non-human primates are also aware of death. We investigate this issue by comparing the behaviours of monkeys and great apes toward helpless conspecifics, basing our analysis on published reports. We first examine the behaviours of mothers towards the body of their dead offspring. They may carry the corpse for days or more before abandoning it. They groom, inspect and protect it, sometimes allowing group members to explore it, and rare cases of cannibalism have been reported. No significant difference is observed in the way that monkeys and great apes treat the bodies of infants. We then examine responses to collapsed (still able to move and react) and inanimate (unresponsive or dead) conspecifics. Monkeys and great apes guard, care for and inspect their helpless partners, and also manipulate and mobilise them. Through these actions, individuals may inform themselves about the state of their partners, test their responsiveness and/or attempt to rouse them. It appears that only chimpanzees and gorillas show violent action such as display behaviours and the rough treatment of bodies. They can also make distress calls, and periods of “stunned silence” sometimes occur in chimpanzees, indicating that they are experiencing intense emotion. Finally, we argue that while both monkeys and great apes detect body dysfunction through the victims’ inability to wake up and move, only great apes can understand that something serious has happened. The signs of emotional disturbance reported in them indicate that they may believe that inanimate conspecifics have entered a state of “dormancy”, meaning that they are unlikely to regain wakefulness. However, there is no evidence that any non-human primates are aware of mortality.
Effect of fluctuations on the superfluid-supersolid phase transition on the lattice

description: We derive a controlled expansion into mean field plus fluctuations for the extended Bose-Hubbard model, involving interactions with many neighbors on an arbitrary periodic lattice, and study the superfluid-supersolid phase transition. Near the critical point, the impact of (thermal and quantum) fluctuations on top of the mean field grows, which entails striking effects, such as negative superfluid densities and thermodynamical instability of the superfluid phase -- earlier as expected from mean-field dynamics. We also predict the existence of long-lived "supercooled" states with anomalously large quantum fluctuations.

Chthonic Legal Traditions towards Emic Understandings of Australian First Nations Constitutionalism: 'Rooted' Constitutionalism and a Foundational Conceptual Apparatus for Inquiries into Australian First Nations Legal Orders (Advance)
Creators: name: Randazzo, Maria
Publisher: name: Monash University
Year: 2020
Subjects: subject: Law
subject: FOS: Law

description: First Nations constitutionalism unfolds within a chthonic legal tradition which is incommensurable with most of the positivist theoretical and conceptual models deployed to investigate Westphalian constitutional systems. The irreducibility of analysis of chthonic constitutional traditions with such models of constitutionalism calls, on the one hand, for rethinking positivistic approaches to legal reasoning and rationalisation and, on the other hand, for identifying new conceptual grids in charting the normative and legal landscape of Indigenous constitutionalism. With specific reference to Australian First Nations constitutionalism, the purpose of this paper is to suggest the adoption of a conceptual apparatus for its investigation which reflects 'emic' understandings of what Indigenous legal orders are and how they operate. In doing so, the paper subsumes Australian First Nations constitutionalism into Mills’s theoretical elaboration of ‘rooted constitutionalism’ and argues that such a ‘rooted’ kind of constitutionalism needs to be expounded through foundational concepts such as nomos, myths, and legal traditions which are experientially and culturally grounded in the lifeworld that sustain Australian First Nations constitutional traditions. Such a conceptual apparatus draws mainly from the theoretical framework elaborated by legal pluralism and legal theory to deal with the contemporary normative complexities of stateless legal orders. It is a macro-level conceptual apparatus that would be foundational to ‘etic’ understanding and theorisation of First Nations Australian constitutionalism.

description: We derive the solutions of gravitational waves in the future (F) expanding and the past (P) shrinking Kanser spacetimes as well as in the left (L) and right (R) Rindler wedges in the Regge-Wheeler gauge. The solutions for all metric components are obtained in an analytic form in each region. We identify the master variables, which are equivalent to massless scalar fields, to describe the gravitational degrees of freedom for the odd parity and even parity modes under the transformation in the two-dimensional plane symmetric space. Then, the master variables are quantized, and we develop the quantum field theory of the gravitational waves in the F, P, L, and R regions. We demonstrate that the mode functions of the quantized gravitational waves in the left and right Rindler wedges are obtained by an analytic continuation of the left-moving and right-moving wave modes in Kasner spacetime. On the basis of these analyses, we discuss the Unruh effect of quantized gravitational waves for an observer in a uniformly accelerated motion in Minkowski spacetime.

description: Few micro-level empirical papers have addressed the impact of the patent system on industry structure. Using firm-level patent data for public and private firms in plant biotechnology, we develop a measure of patent enforceability. Duration models show that patent statistics are a useful predictor of the timing of merger activity. We find that patent enforceability is an important factor influencing the likelihood of mergers. Mergers in plant biotechnology may be partially motivated by the enforcement of patent rights when firms have overlapping technologies; some of the merger activity may be explained by attempts to avoid mutually blocking technology, as exemplified in the case of Roundup Ready corn.
The hormonal regulation of cadherin-11 expression in the human endometrium
Creators: name: Chen, George Tzer-Chou
Publisher: name: University of British Columbia
Year: 2009

description: The human endometrium undergoes cyclic proliferation, differentiation, and shedding in response to 17R-estradiol and progesterone. To date, the cellular mechanisms by which these gonadal steroids regulate the formation and organisation of this dynamic tissue remain poorly understood. We have recently determined that cadherin-11, a type 2 classical cadherin, is spatiotemporally expressed in the human endometrium during the menstrual cycle. In particular, cadherin-11 is first detected in the endometrial stroma during the secretory phase of the menstrual cycle with maximum expression levels being observed in the decidua of pregnancy. As the cadherins play critical roles in the formation and organisation of tissues during embryonic development, we hypothesised that the morphogenetic effects exerted by gonadal steroids on the endometrium may be mediated, at least in part, by their ability to regulate stromal cadherin-11 expression levels. In these studies, we have examined the ability of 176-estradiol, progesterone, and dihydrotestosterone, alone or In combination, to regulate cadherin-11 mRNA and protein expression levels in cultured human endometrial stromal cells. Progesterone, but not estradiol or dihydrotestosterone, increased stromal cadherin-11 mRNA and protein expression levels over time in culture. However, 1 7S-estradiol was capable of potentiating the stimulatory effects of progesterone on stromal cadherin-11 expression. Maximum levels of cadherin-11 were detected in endometrial stromal cells which had undergone decidualisation in response to long term culture in the presence of these two gonadal steroids. Cadherin-11 expression in decidualised endometrial stromal cells was effectively reduced by the antiprogestin RU486, the antiestrogen ICI 182,780, and steroid withdrawal suggesting that the progesterone-mediated increase in stromal cadherin-11 expression was dependent on estrogens. Finally, progesterone increased the levels of the mRNA transcript encoding 6 - catenin, a cadherin-associated cytoplasmic protein, in these primary cell cultures. This is the first demonstration that gonadal steroids are capable of coordinately regulating cadherin-11 and S-catenin expression in a mammalian cell type. Collectively, these studies not only add to our understanding of the cell biology of this novel cadherin subtype but give us insight into the cellular mechanisms by which gonadal steroids regulate the remodeling processes that occur in the endometrium during each menstrual cycle.

description: The lens used by the courts and much of the antitrust literature on predatory selling and/or buying is based on partial equilibrium methodology. We demonstrate that such methodology is unreliable for assessments of predatory monopoly or monopsony conduct. In contrast to the typical two-stage dynamic analysis involving a predation period followed by a recoupment period, we advance a general equilibrium analysis that demonstrates the critical role of related industries and markets. Substitutability versus complementarity of both inputs and outputs is critical. With either monopolistic or monopsonistic market power (but not both), neither predatory overselling nor predatory overbuying is profitably sustainable. Two-stage predation/recoupment is profitable only with irreversibility in production and cost functions, unlike typical estimated forms from the production economic literature. However, when the market structure admits both monopolistic and monopsonistic behavior, predatory overbuying can be profitably sustainable while overselling cannot. Useful distinctions are drawn between contract versus non-contract markets for input markets.

description: We consider the semi-classical expansion of the Bunch-Davies wavefunction with future boundary condition in position space for a real scalar field, conformally coupled to a classical de Sitter background in the expanding Poincaré patch with quartic selfinteraction. In the future boundary limit the wave function takes the form of the generating functional of a Euclidean conformal field theory for which we calculate the anomalous dimensions of the double trace deformations at one loop order using results obtained from Euclidean Anti de Sitter space. We find analytic expressions for some subleading twist operators and an algorithm to obtain expressions for general twist.

description: Planar L-loop maximally helicity violating amplitudes in N = 4 supersymmetric Yang-Mills theory are believed to possess the remarkable property of satisfying iteration relations in L. We propose a simple new method for studying the iteration relations for four-particle amplitudes which involves the use of certain linear differential operators and eliminates the need to fully evaluate any loop integrals. We carry out this procedure in explicit detail for the two-loop amplitude and argue that this method can be used to prove the iteration relations to all loops up to polynomials in logarithms.

Expropriation clauses in international treaties solve post-investment moral hazard problems such as hold-ups.

A police powers carve-out from the definition of expropriation can be Pareto-improving and can increase the level of foreign investment.

description: The rapid release of accurate sky localization for gravitational-wave candidates is crucial for multi-messenger observations. During the third observing run of Advanced LIGO and Advanced Virgo, automated gravitational-wave alerts were publicly released within minutes of detection. Subsequent inspection and analysis resulted in the eventual retraction of a fraction of the candidates. Updates could be delayed by up to several days, sometimes issued during or after exhaustive multi-messenger followup campaigns. We introduce GWSkyNet, a real-time framework to distinguish between astrophysical events and instrumental artefacts using only publicly available information from the LIGO-Virgo open public alerts. This framework consists of a non-sequential convolutional neural network involving sky maps and metadata. GWSkyNet achieves a prediction accuracy of 93.5% on a testing data set.
Revisiting Section 32(1) of the Victorian Charter: Strained Constructions and Legislative Intention

description: This article revisits s 32(1) of the Charter of Human Rights and Responsibilities Act 2006 (Vic). In particular, the article examines the potential ability of the courts to deploy s 32(1) to reach ‘strained’ constructions and ‘depart’ from legislative intention. This article disputes the following three propositions from the post-Momcilovic v The Queen jurisprudence in the Victorian Court of Appeal. Firstly, s 32(1) does not allow for a departure from the ‘ordinary meaning’ of a statutory provision (an ordinary meaning usually denotes a literal and grammatical, ie not strained, meaning). Secondly, s 32(1) does not allow for a departure from, or overriding of, legislative intention upon enactment. Thirdly, the qualifications placed on s 32(1) are such that it will not usually permit the ‘reading in’ or ‘reading down’ of words as techniques used to reach strained constructions. The article also argues that issues as to s 32(1)’s strength and methodology appear to have been conflated in the recent jurisprudence. It concludes that as the jurisprudence currently stands, s 32(1)’s ability to reach strained constructions is weaker than the principle of legality. This is inconsistent with s 32(1) being at least equal to the principle of legality.
Arm's-Length Transactions as a Source of Incomplete Cross-Border Transmission: the Case of Autos

description: A growing share of international trade occurs through intra-firm transactions, transactions between domestic and foreign subsidiaries of a multinational firm. The difficulties associated with writing and enforcing a vertical contract compound when a product must cross a national border, and may explain the high rate of multinational trade across such borders. We show that this common crossborder organization of the firm may have implications for the well-documented incomplete transmission of shocks across such borders. We present new evidence of a positive relationship between an industry's share of multinational trade and its rate of exchange-rate pass-through to prices. We then develop a structural econometric model with both manufacturers and retailers to quantify how firms' organization of their activities across national borders affects their pass-through of a foreign cost shock. We apply the model to data from the auto market. Counterfactual experiments show why cross-border transmission may be much higher for a multinational than for an arm's-length transaction. In the structural model, firms' pass-through of foreign cost shocks is on average 29 percentage points lower in arm's-length than in multinational transactions, as the higher markups from a double optimization along the distribution chain create more opportunity for markup adjustment following a shock. As arm's-length transactions account for about 60 percent of U.S. imports, this difference may explain roughly 20 percent of the incomplete transmission of foreign-cost shocks to the U.S. in the aggregate.

description: Our results suggest that the anticipated path of China's Carbon Dioxide (CO2) emissions has dramatically increased over the last five years. The magnitude of the projected increase in Chinese emissions out to 2015 is several times larger than reductions embodied in the Kyoto Protocol. Our estimates are based on a unique provincial level panel data set from the Chinese Environmental Protection Agency. This dataset contains considerably more information relevant to the path of likely Chinese greenhouse gas emissions than national level time series models currently in use. Model selection criteria clearly reject the popular static environmental Kuznets curve specification in favor of a class of dynamic models with spatial dependence.

description: We show how gravitational-wave observations of binary black hole (BBH) mergers can constrain the physical characteristics of a scalar field cloud parameterized by mass $\tildeμ$ and strength $ϕ_0$ that may surround them. We numerically study the inspiraling equal-mass, non-spinning BBH systems dressed in such clouds, focusing especially on the gravitational-wave signals emitted by their merger-ringdown phase. These waveforms clearly reveal that larger values of $\tildeμ$ or $ϕ_0$ cause bigger changes in the amplitude and frequency of the scalar-field-BBH ringdown signals. We show that the numerical waveforms of scalar-field-BBHs can be modelled as chirping sine-Gaussians, with matches in excess of 95%. This observation enables one to employ computationally expensive Bayesian studies for estimating the parameters of such binaries. Using our chirping sine-Gaussian signal model we establish that observations of BBH mergers at a distance of 450 Mpc will allow to distinguish BBHs without any scalar field from those with a field strength $ϕ_0 \gtrsim 5.5\times 10^{-3}$, at any fixed value of $\tilde μ\in [0.3,0.8]$, with 90% confidence or better, in single detectors with Advanced LIGO/Virgo type sensitivities. This provides hope for the possibility of determining or constraining the mass of ultra-light bosons with gravitational-wave observations of BBH mergers.

description: The phase diagram of a dissipative particle in a periodic potential and a magnetic field is studied in the weak barrier limit and in the tight-biding regime. For the case of half flux per plaquette, and for a wide range of values of the dissipation, the physics of the model is determined by a non trivial fixed point. A combination of exact and variational results is used to characterize this fixed point. Finally, it is also argued that there is an intermediate energy scale that separates the weak coupling physics from the tight-binding solution.

description: This paper extends the Stahl-Rubinstein model of bilateral bargaining to incorporate many players and multidimensional issue spaces. A central feature of our framework is that in each round of negotiations, a proposer is selected randomly. Our bargaining model consists of a sequence of finite-horizon games, in which the horizon increases without bound. A solution to our model is a limit of equilibrium outcomes for the finite horizon games. A necessary condition for existence of a deterministic solution is that the limit outcome belongs to the core of the underlying bargaining problem. Solutions, if they exist, are generically unique. Two sets of sufficiency conditions for existence are presented. The paper concludes with examples and applications. In particular, we consider bipolar negotiations between two factions, and show that there is a positive relationship between the cohesiveness of one faction relative to the other and its effectiveness in securing the common goals to its members.

description: The possibility of non-constant discounting is important in environmental and resource management problems where current decisions affect welfare in the far-distant future, as with climate change. The difficulty of analyzing models with non-constant discounting limits their application. We describe and provide software to implement an algorithm to numerically obtain a Markov Perfect Equilibrium for an optimal control problem with non-constant discounting. The software is available online. We illustrate the approach by studying welfare and observational equivalence for a particular renewable resource management problem.

Additional conserved quantities associated with extra symmetry govern wide variety of physics problems, from planetary motion till fine and hyperfine structures of atomic spectra. In this paper we present a simple derivation of hidden symmetry operator in relativistic quantum mechanics for the Dirac equation in the Coulomb field. We established that this operator may be reduced to the one introduced by Johnson and Lippmann. It is worthwhile to notice that this operator was discussed in literature very rarely and so is not known well among physicists and was omitted even in the recent textbooks on relativistic quantum mechanics and/or quantum electrodynamics.

description: In an attempt to evaluate the effectiveness of various safety improvements on approximately five miles of I 75 in northern Kentucky, a before-and-after analysis of accidents was conducted. Safety improvements were: 1) a variable message signing system in the northbound direction; 2) a New Jersey-type median barrier wall; and 3) general improvements such as guardrail end treatments, break-away sign installations, contour grading, etc.  Results indicate the safety improvements were effective in reducing the overall accident rate. Separate analysis also revealed that variable message signs were effective in bringing about a significant reduction in accident rates. There were no fatalities during either of the data collection periods. However, accident severity increased after the improvements. Results were influenced by low skid resistance, continued wear in wheel tracks, and increasing congestion throughout the study section.
Revisiting Section 32(1) of the Victorian Charter: Strained Constructions and Legislative Intention (Advance)

subject: FOS: Law

description: This article revisits s 32(1) of the Charter of Human Rights and Responsibilities Act 2006 (Vic). In particular, the article examines the potential ability of the courts to deploy s 32(1) to reach ‘strained’ constructions and ‘depart’ from legislative intention. This article disputes the following three propositions from the post-Momcilovic v The Queen jurisprudence in the Victorian Court of Appeal. Firstly, s 32(1) does not allow for a departure from the ‘ordinary meaning’ of a statutory provision (an ordinary meaning usually denotes a literal and grammatical, ie not strained, meaning). Secondly, s 32(1) does not allow for a departure from, or overriding of, legislative intention upon enactment. Thirdly, the qualifications placed on s 32(1) are such that it will not usually permit the ‘reading in’ or ‘reading down’ of words as techniques used to reach strained constructions. The article also argues that issues as to s 32(1)’s strength and methodology appear to have been conflated in the recent jurisprudence. It concludes that as the jurisprudence currently stands, s 32(1)’s ability to reach strained constructions is weaker than the principle of legality. This is inconsistent with s 32(1) being at least equal to the principle of legality.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1973
Subjects: subject: Transportation Engineering

description: In a field evaluation of vibratory rollers, an end-result specification based on a statistical analysis of densities obtained on previous construction projects indicated 98 percent of laboratory density (Marshall) to be desired for Bituminous Concrete, Class I Base. The minimum average of 5 density tests was set at 96.4 percent. Conventional rollers, vibratory rollers, and combinations thereof were qualified on the basis of density-growth curves determined on one or more 1000-foot test sections. An overall average compaction of 97.8 percent of Marshall density was obtained on the Cumberland Parkway project. Similar controls initiated on the Green River Parkway project were discontinued.

description: We present the Galactic Radio Explorer (GReX), an all-sky monitor to probe the brightest bursts in the radio sky. Building on the success of STARE2, we will search for fast radio bursts (FRBs) emitted from Galactic magnetars as well as bursts from nearby galaxies. GReX will search down to ten microseconds time resolution, allowing us to find new super giant radio pulses from Milky Way pulsars and study their broadband emission. The proposed instrument will employ ultra-wide band (0.7-2 GHz) feeds coupled to a high performance (receiver temperature 10 K) low noise amplifier (LNA) originally developed for the DSA-110 and DSA-2000 projects. In GReX Phase I (GReX-I), unit systems will be deployed at Owens Valley Radio Observatory (OVRO) and Big Smoky Valley, Nevada. Phase II will expand the array, placing feeds in India, Australia, and elsewhere in order to build up to continuous coverage of nearly 4$π$ steradians and to increase our exposure to the Galactic plane. We model the local magnetar population to forecast for GReX, finding the improved sensitivity and increased exposure to the Galactic plane could lead to dozens of FRB-like bursts per year.
Making Violence against Women (In)visible? Restrictions on Media Reporting of Intervention Orders

description: Journalists are often criticised for their reporting of violence against women (‘VAW’). Media coverage has been described as lacking in context, thus presenting VAW as individual incidents rather than as a social problem, as being over-reliant on police as sources, and generally distorting the reality of that violence. However, much of this criticism ignores the legal restrictions placed on the media. This article focuses on one such restriction, that contained in family violence intervention order legislation. It explores whether the reporting of intervention orders should be subject to any restrictions, especially in the context of reporting on intimate partner homicides (‘IPHs’). We conclude that there are good reasons to provide for restrictions on reporting, provided the subject of the order is able to give consent to publication of the information, but that the removal of the restriction in the context of IPHs would make a small, but important, contribution to increasing public understanding of such homicides and VAW.

description: The Government of India (GOI) announced a nationwide lockdown starting 25th March 2020 to contain the spread of COVID-19, leading to an unprecedented decline in anthropogenic activities and in turn improvements in ambient air quality. This is the first study to focus on highly time-resolved chemical speciation and source apportionment of PM$_{2.5}$ to assess the impact of the lockdown and subsequent relaxations on the sources of ambient PM$_{2.5}$ in Delhi, India. The elemental, organic, and black carbon fractions of PM$_{2.5}$ were measured at the IIT Delhi campus from February 2020 to May 2020. We report source apportionment results using positive matrix factorization (PMF) of organic and elemental fractions of PM$_{2.5}$ during the different phases of the lockdown. The resolved sources such as vehicular emissions, domestic coal combustion, and semi-volatile oxygenated organic aerosol (SVOOA) were found to decrease by 96%, 95%, and 86%, respectively, during lockdown phase-1 as compared to pre-lockdown. An unforeseen rise in O$_3$ concentrations with declining NO$_x$ levels was observed, similar to other parts of the globe, leading to the low-volatility oxygenated organic aerosols (LVOOA) increasing to almost double the pre-lockdown concentrations during the last phase of the lockdown. The effect of the lockdown was found to be less pronounced on other resolved sources like secondary chloride, power plants, dust-related, hydrocarbon-like organic aerosols (HOA), and biomass burning related emissions, which were also swayed by the changing meteorological conditions during the four lockdown phases. The results presented in this study provide a basis for future emission control strategies, quantifying the extent to which constraining certain anthropogenic activities can ameliorate the ambient air.

description: We study semiconductor nanowires coupled to a bilayer of a disordered superconductor and a magnetic insulator, motivated by recent experiments reporting possible Majorana-zero-mode signatures in related architectures. Specifically, we pursue a quasiclassical Usadel equation approach that treats superconductivity in the bilayer self-consistently in the presence of spin-orbit scattering, magnetic-impurity scattering, and Zeeman splitting induced by both the magnetic insulator and a supplemental applied field. Within this framework we explore prospects for engineering topological superconductivity in a nanowire proximate to the bilayer. We find that a magnetic-insulator-induced Zeeman splitting, mediated through the superconductor alone, cannot induce a topological phase since the destruction of superconductivity (i.e., Clogston limit) preempts the required regime in which the nanowire's Zeeman energy exceeds the induced pairing strength. However, this Zeeman splitting does reduce the critical applied field needed to access the topological phase transition, with fields antiparallel to the magnetization of the magnetic insulator having an optimal effect. Finally, we show that magnetic-impurity scattering degrades the topological phase, and spin-orbit scattering, if present in the superconductor, pushes the Clogston limit to higher fields yet simultaneously increases the critical applied field strength.

description: We propose a gauge invariant expression for the side jump associated with scattering between particular Bloch states. Our expression for the side jump follows from the Born series expansion for the scattering T-matrix in powers of the strength of the scattering potential. Given our gauge invariant side jump expression, it is possible to construct a semiclassical Boltzmann theory of the anomalous Hall effect which expresses all previously identified contributions in terms of gauge invariant quantities and does not refer explicitly to off-diagonal terms in the density-matrix response.
