Hate Speech and Atrocity Prevention in Asia: Patterns, Trends and Strategies
(Brill - Nijhoff, 2023) Jacob, Cecilia; Morada, Noel
This article introduces the conceptual and analytical framework for this special issue on hate speech and atrocity prevention in Asia. It defines hate speech and incitement, and explains the process and context through which hate speech and incitement operates as a risk factor for atrocities. It also provides an explanation of the international legal framework regulating hate speech and incitement that informs the approach of the articles in this issue.
Testing core creation in hydrodynamical simulations using the HI kinematics of field dwarfs
(EDP Sciences, 2017) Papastergis, E.; Ponomareva, Anastasia
Process that is attributed to star formation-related baryonic feedback. Core creation is regarded as one of the most promising solutions to potential issues faced by lambda cold dark matter (Lambda CDM) cosmology on small scales. For example, the reduced dynamical mass enclosed by cores can explain the low rotational velocities measured for nearby dwarf galaxies, thus possibly lifting the seeming contradiction with the Lambda CDM expectations(the so-called "too big to fail" problem). Here we test core creation as a solution of cosmological issues by using a sample of dwarfs with measurements of their atomic hydrogen (HI) kinematics extending to large radii. Using the NIHAO hydrodynamical simulation as an example, we show that core creation can successfully reproduce the kinematics of dwarfs with small kinematic radii,R less than or similar to 1.5 kpc. However, the agreement with observations becomes poor once galaxies with kinematic measurements extending beyond the core region, R approximate to 1.5-4 kpc, are considered. This result illustrates the importance of testing the predictions of hydrodynamical simulations that are relevant for cosmology against a broad range of observational samples. We would like to stress that our result is valid only under the following set of assumptions: i) that our sample of dwarfs with HI kinematics is representative of the overall population of field dwarfs; ii) that there are no severe measurement biases in the observational parameters of our HI dwarfs (e.g., related to inclination estimates); and iii) that the HI velocity fields of dwarfs are regular enough to allow the recovery of the true enclosed dynamical mass.
Private capital formation in Australia : estimates 1861-1900 / by N.G. Butlin.
(Canberra : Dept. of Economics, Australian National University, 1955., 1955) Butlin, N. G. (Noel George); Australian National University. Department of Economics (contributor.)
Australian capital formation during 1861- 1900 is unexplored territory. Because of our ignorance of the subject and the mass of estimates printed in this and the earlier companion monograph, the chapter is intended to relate, in broad out“ line, the course and pattern of Australian public and private capital formation and to raise one or two questions for discussion.
Neutrinos from type Ia supernovae: The gravitationally confined detonation scenario
(American Physical Society, 2017) Wright, Warren P.; Kneller, James P.; Ohlmann, Sebastian T..; Röpke, F K; Scholberg, Kate; Seitenzahl, Ivo
Despite their use as cosmological distance indicators and their importance in the chemical evolution of galaxies, the unequivocal identification of the progenitor systems and explosion mechanismof normal type Ia supernovae (SNe Ia) remains elusive. The leading hypothesis is that such a supernova is a thermonuclear explosion of a carbon-oxygen white dwarf, but the exact explosion mechanism is still a matter of debate. Observation of a galactic SN Ia would be of immense value in answering the many open questions related to these events. One potentially useful source of information about the explosion mechanism and progenitor is the neutrino signal because the neutrinos fromthe different mechanisms possess distinct spectra as a function of time and energy. In this paper, we compute the expected neutrino signal from a gravitationally confined detonation (GCD) explosion scenario for a SN Ia and show how the flux at Earth contains features in time and energy unique to this scenario. We then calculate the expected event rates in the Super-K, Hyper-K, JUNO, DUNE, and IceCube detectors and find both Hyper-K and IceCube will see a fewevents for aGCDsupernova at 1 kpc or closer, while Super-K, JUNO, and DUNE will see events if the supernova is closer than similar to 0.3 kpc. The distance and detector criteria needed to resolve the time and spectral features arising from the explosion mechanism, neutrino production, and neutrino oscillation processes are also discussed. The neutrino signal fromthe GCD is then compared with the signal froma deflagration-to-detonation transition (DDT) explosion model computed previously. We find the overall event rate is the most discriminating feature between the two scenarios followed by the event rate time structure. Using the event rate in the Hyper-K detector alone, the DDTcan be distinguished fromtheGCDat 2 sigma if the distance to the supernova is less than 2.3 kpc for a normal mass ordering and 3.6 kpc for an inverted ordering.
'Kill Two Million of Them': Institutionalised Hate Speech, Impunity and 21st Century Atrocities in India
(Brill - Nijhoff, 2023) Jacob, Cecilia; Kanth, Mujeeb
Hate speech and incitement have been instrumental in atrocity crimes that have occurred in India, even prior to its independence. These atrocities include targeted killings of minorities based on religious and ethnic identity, and demonstrate persistent features of systematic, orchestrated violence that is fuelled by a Hindu nationalist ideology. This ideology is routinely promulgated at the highest levels of political leadership. This article traces both the historical and institutional character of hate speech and incitement in India to understand its repeated manifestation over time. Through case studies of recent violence, it considers the implications of new legal developments, technology and the covid-19 pandemic on the character and dynamic of hate speech, incitement and atrocity violence in India. It considers key reforms and areas for accountability on which the international community could engage the government and civil society in India on the issue of hate speech and incitement to promote atrocity prevention at the domestic level.
