Typhoons, Climate Change, and Climate Injustice in the Philippines
Creators: name: Holden, William N.
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2018

description: This article discusses how climate change causes an intensification of Western North Pacific typhoons and how the effects of such amplified typhoons upon the Philippines exemplify the concept of climate injustice. Using a political ecology approach, the article begins with an examination of the concepts of climate change, climate injustice, background injustice, and compound injustice. This is followed by an examination of the causes of typhoons, the vulnerability of the Philippines to typhoons, and how climate change may generate stronger typhoons. These stronger typhoons that may be produced by climate change, and the risks that they pose to the Philippines, are an example of climate injustice, while the legacy of colonial exploitation in the Philippines is an example of background injustice. The struggles faced by the Philippines in coping with climate change augmented typhoons are an example of compound injustice. The article concludes with a discussion of the reluctance of developed countries, such as Australia, Canada, and the United States, to reduce their greenhouse gas emissions notwithstanding the consequences these emissions have on countries such as the Philippines.

description: We consider a spin-1/2 anisotropic XY model with time-dependent spin-spin coupling as means of creating long-distance entanglement. We predict the emergence of significant entanglement between the first and the last spin whenever the ac part of the coupling has a frequency matching the Zeeman splitting. In particular, we find that the concurrence assumes its maximum with a vanishing dc part. Mapping the time-dependent Hamiltonian within a rotating-wave approximation to an effective static model provides qualitative and quantitative understanding of this entanglement resonance. Numerical results for the duration of the entanglement creation and its length dependence substantiate the effective static picture.

title: The role of probation officers' reports in magistrates' sentencing decisions.
Creators: name: Armitage, Jill
Publisher: name: University of Kent
Year: 2021

description: During the past decade research findings have suggested effective ways for probation officers to work with 4 offenders. At the same time, the Criminal Justice Act 1991 changed the sentencing framework, as well as the manner in which probation officers write court reports and supervise offenders. Both of these chancres led to an increase in the monitoring and evaluation of probation officers' work, and the appropriate targeting of sentence proposals, as well as take-up rates for proposals, took on greater significance and became more closely monitored than ever before. The present study examines the effects of these changes C: I on probation officers' selection and presentation of community sentence proposals, and it looks at factors that affect court rates of take-up for these proposals, includina the offence committed, ender of offender, risk of custody, the presence of social problems and risk 4n of re-offending. The main focus of the study is upon the sentencing choice between community service and probation, which partly reflects the choice between punishment and rehabilitation. Data relating to sentence proposals and outcomes are analysed using cross-tabulation tables, which provide a readily understood method of examining outcomes relative to proposals. These quantitative analyses are combined with three qualitative studies of written reports, which provide insights into reasons for sentencing decisions not apparent from the statistical data alone. The study discusses ways in which probation officers and magistrates may take differing perspectives concerning the main alms of sentencing and hence may disagree over what constitutes the most appropriate sentence. The study concludes that despite the requirements of both effective practice guidelines and the CJA C) 1991, the probation service has been unsuccessful in convincing magistrates that the probation order is capable C, of achieving multiple sentencing objectives for more serious offenders

These results are then used to calculate nuclear radii and electric monopole (E0) transitions with the same effective operator. The influence of the hexadecapole degree of freedom ($g$ boson) on the correlation between radii and E0 transitions thus established, is discussed.

The Social Base of New Authoritarianism in Southeast Asia: Class Struggle and the Imperial Mode of Living
Creators: name: Schaffar, Wolfram
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2018

description: This research note addresses the question of the social base of new authoritarianism and sketches out new directions for future research. In Europe and the United States, this question has led to highly controversial debates between two camps. One side argues for a class analysis and sees a revolt of the disenfranchised and poor behind the electoral success of the right-wing populists. The other side draws on the concept of the Imperial Model of Living and focuses on a cross-class alliance in the North, defending their unsustainable consumption pattern, which rests on the exploitation of resources, sinks, and cheap labor from the South. It will be argued that a view from Southeast Asia – especially data from Thailand and the Philippines – has the potential to challenge some assumptions of this debate and add important insights. Here, a rising middle class has been in the focus of the debate on democratization in the 1980s/1990s. Starting with the Asia Crisis in 1997/1998, the rise of the new authoritarianism has also been linked to middle-class mobilization. Finally, due to the proximity to China and historical links, the re-orientation of middle classes towards China provides insights into the micro processes behind the shift in the global economic system.

description: Complex systems such as ecological communities and neuron networks are essential parts of our everyday lives. These systems are composed of units which interact through intricate networks. The ability to predict sudden changes in the dynamics of these networks, known as critical transitions, from data is important to avert disastrous consequences of major disruptions. Predicting such changes is a major challenge as it requires forecasting the behaviour for parameter ranges for which no data on the system is available. We address this issue for networks with weak individual interactions and chaotic local dynamics. We do this by building a model network, termed an {\em effective network}, consisting of the underlying local dynamics and a statistical description of their interactions. We show that behaviour of such networks can be decomposed in terms of an emergent deterministic component and a {\em fluctuation} term. Traditionally, such fluctuations are filtered out. However, as we show, they are key to accessing the interaction structure.

description: In this work we classify the subalgebras satisfied by non-geometric Q-fluxes in type IIB orientifolds on T^6/(Z_2 x Z_2) with three moduli (S,T,U). We find that there are five subalgebras compatible with the symmetries, each one leading to a characteristic flux-induced superpotential. Working in the 4-dimensional effective supergravity we obtain families of supersymmetric AdS_4 vacua with all moduli stabilized at small string coupling g_s. Our results are mostly analytic thanks to a judicious parametrization of the non-geometric, RR and NSNS fluxes. We are also able to leave the flux-induced C_4 and C_8 RR tadpoles as free variables, thereby enabling us to study which values are allowed for each Q-subalgebra. Another novel outcome is the appearance of multiple vacua for special sets of fluxes. However, they generically have g_s > 1 unless the net number of O3/D3 or O7/D7 sources needed to cancel the tadpoles is large. We also discuss briefly the issues of axionic shift symmetries and cancellation of Freed-Witten anomalies.

description: Quantum state smoothing is a technique to estimate an unknown true state of an open quantum system based on partial measurement information both prior and posterior to the time of interest. In this paper, we show that the smoothed quantum state is an optimal state estimator; that is, it minimizes a risk (expected cost) function. Specifically, we show that the smoothed quantum state is optimal with respect to two cost functions: the trace-square deviation from and the relative entropy to the unknown true state. However, when we consider a related risk function, the linear infidelity, we find, contrary to what one might expect, that the smoothed state is not optimal. For this case, we derive the optimal state estimator, which we call the lustrated smoothed state. It is a pure state, the eigenstate of the smoothed quantum state with the largest eigenvalue.

description: Morphology and structure of galaxies reflect their star formation and assembly histories. We use the framework of mutual information ($\mathrm{MI}$) to quantify interdependence among several structural variables and to rank them according to their relevance for predicting specific star formation rate (SSFR) by comparing the $\mathrm{MI}$ of the predictor variables with SSFR and penalizing variables that are redundant. We apply this framework to study $\sim 3,700$ face-on star-forming galaxies (SFGs) with varying degrees of bulge dominance and central concentration and with stellar mass $M_\star \approx 10^9\,M_\odot - 5\times 10^{11}\,M_\odot$ at redshift $z = 0.02-0.12$. We use the Sloan Digital Sky Survey (SDSS) Stripe 82 deep $i$-band imaging data, which improve measurements of asymmetry and bulge dominance indicators. We find that star-forming galaxies are a multi-parameter family. In addition to $M_\star$, asymmetry emerges as the most powerful predictor of SSFR residuals of SFGs, followed by bulge prominence/concentration. Star-forming galaxies with higher asymmetry and stronger bulges have higher SSFR at a given $M_\star$. The asymmetry reflects both irregular spiral arms and lopsidedness in seemingly isolated SFGs and structural perturbations by galaxy interactions or mergers.

description: The growth of Jovian mass planets during migration in their protoplanetary disks is one of the most important problems that needs to be solved in light of observations of the exosolar planets. Studies of the migration of planets in standard gas disk models routinely show that migration is too fast to form Jovian planets, and that such migrating planetary cores generally plunge into the central stars in less than a Myr. In previous work, we have shown that a poorly ionized, less viscous region in a protoplanetary disk called a dead zone slows down the migration of fixed-mass planets. In this paper, we extend our numerical calculations to include dead zone evolution along with the disk, as well as planet formation via accretion of rocky and gaseous materials. Using our symplectic-integrator-gas dynamics code, we find that dead zones, even in evolving disks wherein migrating planets grow by accretion, still play a fundamental role in saving planetary systems. We demonstrate that Jovian planets form within 2.5 Myr for disks that are ten times more massive than a minimum mass solar nebula (MMSN) with an opacity reduction and without slowing down migration artificially. Our simulations indicate that protoplanetary disks with an initial mass comparable to the MMSN only produce Neptunian mass planets. We also find that planet migration does not help core accretion as much in the oligarchic planetesimal accretion scenario as it was expected in the runaway accretion scenario. Therefore we expect that an opacity reduction (or some other mechanisms) is needed to solve the formation timescale problem even for migrating protoplanets, as long as we consider the oligarchic growth. We also point out a possible role of a dead zone in explaining long-lived, strongly accreting gas disks.

description: Anomalous dimensions of high-twist Wilson operators in generic gauge theories occupy a band of width growing logarithmically with their conformal spin. We perform a systematic study of its fine structure in the autonomous SL(2) subsector of the dilatation operator of planar N=4 super Yang-Mills theory which is believed to be integrable to all orders in 't Hooft coupling. We resort in our study on the framework of the Baxter equation to unravel the properties of the ground state trajectory and the excited trajectories in the spectrum. We use two complimentary approaches in our analysis based on the asymptotic solution of the Baxter equation and on the semiclassical expansion to work out the leading asymptotic expression for the trajectories in the upper and lower part of the band and to find how they are modified by the perturbative corrections.

description: We investigate the origin of Paris's law, which states that the velocity of a crack at subcritical load grows like a power law, $da/dt \sim (ΔK)^{m}$, where $ΔK$ is the stress intensity factor amplitude. Starting from a damage accumulation function proportional to $(Δσ)^γ$, $Δσ$ being the stress amplitude, we show analytically that the asymptotic exponent $m$ can be expressed as a piecewise-linear function of the %damage accumulation exponent $γ$, namely, $m=6-2γ$ for $γ< γ_{c}$, and $m=γ$ for $γ\ge γ_{c}$, reflecting the existence of a critical value $γ_{c}=2$. %In this way, here we discover the existence of a critical %value $γ_{c}=2$ characterized by a scaling law with a critical %exponent separating two regimes of different linear functions $m %(γ)$. We performed numerical simulations to confirm this result for finite sizes. Finally, we introduce bounded disorder in the breaking thresholds and find that below $γ_{c}$ disorder is relevant, i.e., the exponent $m$ is changed, while above $γ_{c}$ disorder is irrelevant.

description: Young massive stars in the central parsec of our Galaxy are best explained by star formation within at least one, and possibly two, massive self-gravitating gaseous discs. With help of numerical simulations, we here consider whether the observed population of young stars could have originated from a large angle collision of two massive gaseous clouds at R approx. 1 parsec from Sgr A*. In all the simulations performed, the post-collision gas flow forms an inner, nearly circular gaseous disc and one or two eccentric outer filaments, consistent with the observations. Furthermore, the radial stellar mass distribution is always very steep, Sigma proportional to R^-2, again consistent with the observations. All of our simulations produce discs that are warped by between 30 to 60 degrees, in accordance with the most recent observations. The 3D velocity structure of the stellar distribution is sensitive to initial conditions (e.g., the impact parameter of the clouds) and gas cooling details. For example, the runs in which the inner disc is fed intermittently with material possessing fluctuating angular momentum result in multiple stellar discs with different orbital orientations, contradicting the observed data. In all the cases the amount of gas accreted by our inner boundary condition is large, enough to allow Sgr A* to radiate near its Eddington limit over approx. 10^5 years. This suggests that a refined model would have physically larger clouds (or a cloud and a disc such as the circumnuclear disc) colliding at a distance of a few parsecs rather than 1 parsec as in our simulations.

description: We present both time-averaged and time-resolved transport measurements of a two-dimensional electron (Wigner) crystal on the surface of superfluid helium confined in a narrow microchannel. We find that the field-current characteristics of the driven crystal obtained by the time-averaged measurements exhibit oscillations and negative differential conductivity. This unusual transport behavior was observed previously by Glasson et al. [Phys. Rev. Lett. 87, 176802 (2001)] and was attributed to a nonequilibrium transition of the electron system to a novel dynamically ordered phase of current filaments aligned along the channels. Contrarily to this explanation, our time-resolved transport measurements reveal that oscillating field-current characteristics appear due to dynamical decoupling (slipping) and recoupling (sticking) of the uniform electron crystal to the liquid helium substrate. Our result demonstrates that this unusual non-linear transport effect is intrinsic, does not depend on the device geometry, and is associated with the dynamical interaction of Wigner crystal with the surface excitations of the liquid substrate.

The feasibility of the proposal is addressed.

description: Magnetic reconnection plays a crucial role in violent energy conversion occurring in the environments of high electrical conductivity, such as the solar atmosphere, magnetosphere, and fusion devices. We focus on the morphological features of the process in two different environments, the solar atmosphere and the geomagnetic tail. In addition to indirect evidence that indicates reconnection in progress or having just taken place, such as auroral manifestations in the magnetosphere and the flare loop system in the solar atmosphere, more direct evidence of reconnection in the solar and terrestrial environments is being collected. Such evidence includes the reconnection inflow near the reconnecting current sheet, and the outflow along the sheet characterized by a sequence of plasmoids. Both turbulent and unsteady Petschek-type reconnection processes could account for the observations. We also discuss other relevant observational consequences of both mechanisms in these two settings. While on face value, these are two completely different physical environments, there emerge many commonalities, for example, an Alfven speed of the same order of magnitude, a key parameter determining the reconnection rate. This comparative study is meant as a contribution to current efforts aimed at isolating similarities in processes occurring in very different contexts in the heliosphere, and even in the universe.

Pigeons discriminate durations of food access better than durations of light
Creators: name: Spetch, Marcia Louise
Publisher: name: University of British Columbia
Year: 2010

description: In the present experiments stimulus control of pigeons' keypecking by the duration of food access was compared with control by the duration of light. These experiments were designed to extend previous research on three topics within the stimulus control literature: 1) stimulus control by food, 2) comparisons between the effectiveness of different stimuli in controlling behavior, and 3) control by stimulus duration. In Experiment 1, a go/no-go procedure was used to compare control of pigeons' keypecking by food-access duration with control by light duration. Pecks to an illuminated key were reinforced with grain following 10-sec presentations of food access or houselight, but not after 5-sec presentations of either stimulus. Each of the five subjects discriminated food-access duration faster and to a consistently greater degree than light duration. In four between-subject systematic replications, pigeons discriminated food-access duration better than the duration of a localized light, the feeder light, and a keylight, and with either water or food as reinforcement. Experiment 2 demonstrated the generality of these results across discrimination procedures. In this experiment, control by food-access duration was compared with control by light duration under a conditional right-left choice procedure (two pigeons), and a delayed symbolic matching-to-sample procedure (six pigeons). Under both, accuracy was greater on food-access trials than on light trials. In Experiment 3, two pigeons received generalization tests with durations of food access and light that were intermediate to the training values. The results showed that responding was controlled by the duration dimension for both stimuli. The excellent control by food access in these experiments is consistent with previous evidence that food is an effective and memorable stimulus for animals, and the difference in control by the duration of food and light provides empirical support for the common assumption that stimuli differ in their effectiveness of control. Several advantages of using a duration paradigm to compare control by different stimuli are discussed. This research, which demonstrates that the stimulus can play an important role in the accuracy of duration discriminations, also has implications for the study of control by stimulus duration, and for theories of timing processes in animals.

description: We present a measurement of the electron-capture branch of $^{100}$Tc. Our value, $B(\text{EC}) = (2.6 \pm 0.4) \times 10^{-5}$, implies that the $^{100}$Mo neutrino absorption cross section to the ground state of $^{100}$Tc is roughly one third larger than previously thought. Compared to previous measurements, our value of $B(\text{EC})$ prevents a smaller disagreement with QRPA calculations relevant to double-$β$ decay matrix elements.

description: The standard explanation for large pulsar glitches involves transfer of angular momentum from an internal superfluid component to the star's crust. This model requires an instability to trigger the sudden unpinning of the vortices by means of which the superfluid rotates. This Letter describes a new instability that may play this role. The instability, which is associated with the inertial r-modes of a superfluid neutron star, sets in once the rotational lag in the system reaches a critical level. We demonstrate that our model is in good agreement with observed glitch data, suggesting that the superfluid r-mode instability may indeed be the mechanism that triggers large pulsar glitches.

description: In this paper, the response of single three-dimensional phantom and self-avoiding polymers to localized step strains are studied for two cases in the absence of hydrodynamic interactions: (i) polymers tethered at one end with the strain created at the point of tether, and (ii) free polymers with the strain created in the middle of the polymer. The polymers are assumed to be in their equilibrium state before the step strain is created. It is shown that the strain relaxes as a power-law in time $t$ as $t^{-η}$. While the strain relaxes as $1/t$ for the phantom polymer in both cases; the self-avoiding polymer relaxes its strain differently in case (i) than in case (ii): as $t^{-(1+ν)/(1+2ν)}$ and as $t^{-2/(1+2ν)}$ respectively. Here $ν$ is the Flory exponent for the polymer, with value $\approx0.588$ in three dimensions. Using the mode expansion method, exact derivations are provided for the $1/t$ strain relaxation behavior for the phantom polymer. However, since the mode expansion method for self-avoiding polymers is nonlinear, similar theoretical derivations for the self-avoiding polymer proves difficult to provide. Only simulation data are therefore presented in support of the $t^{-(1+ν)/(1+2ν)}$ and the $t^{-2/(1+2ν)}$ behavior. The relevance of these exponents for the anomalous dynamics of polymers are also discussed.

description: The development of spintronic oscillators is driven by their potential applications in radio frequency telecommunication and neuromorphic computing. In this work, we propose a spintronic oscillator based on the chiral coupling in thin magnetic films with patterned anisotropy. With an in-plane magnetized disk imprinted on an out-of-plane magnetized slab, the oscillator takes a polar vortex-like magnetic structure in the disk stabilized by a strong Dzyaloshinskii-Moriya interaction. By means of micromagnetic simulations, we investigate its oscillatory properties under applied spin current and, by placing an ensemble of oscillators in the near vicinity, we demonstrate their synchronization with different resonant frequencies. Finally, we show their potential application in neuromorphic computing using a network with six oscillators.

description: Recent ideas based on the properties of assemblies of frictionless particles in mechanical equilibrium provide a perspective of amorphous systems different from that offered by the traditional approach originating in liquid theory. The relation, if any, between these two points of view, and the relevance of the former to the glass phase, has been difficult to ascertain. In this paper we introduce a model for which both theories apply strictly: it exhibits on the one hand an ideal glass transition and on the other `jamming' features (fragility, soft modes) virtually identical to that of real systems. This allows us to disentangle the different contents and domains of applicability of the two physical phenomena.

description: Deuterated ions are abundant in cold (T=10 K), dense (n=10^5 cm^-3) regions, in which CO is frozen out onto dust grains. In such environments, the deuterium fractionation of such ions can exceed the elemental abundance ratio of D/H by a factor of 10^4. In this paper we use the deuterium fractionation to investigate the evolutionary state of Class 0 protostars. In a sample of 20 protostellar objects, we found a clear correlation between the N2D+/N2H+ ratio and evolutionary tracers. As expected, the coolest, i.e. the youngest, objects show the largest deuterium fractionation. Furthermore, we find that sources with a high N2D+/N2H+ ratio show clear indication for infall.

description: In this paper it has been shown that the neutrino bulk viscous stresses can give rise to the late time acceleration of the universe. It is found that a number of spatially flat FRW models with a negative deceleration parameter can be constructed using neutrino viscosity and one of them mimics a $Λ$CDM model. This does not require any exotic dark energy component or any modification of gravity.

description: Electroweak baryogenesis provides an attractive explanation of the origin of the matter-antimatter asymmetry that relies on physics at the weak scale and thus it is testable at present and near future high-energy physics experiments. Although this scenario may not be realized within the Standard Model, it can be accommodated within the MSSM provided there are new CP-violating phases and the lightest stop mass is smaller than the top-quark mass. In this work we provide an evaluation of the values of the stop (m_{\tilde t}) and Higgs (m_H) masses consistent with the requirements of electroweak baryogenesis based on an analysis that makes use of the renormalization group improved Higgs and stop potentials, and including the dominant two-loop effects at high temperature. We find an allowed window in the (m_{\tilde t},m_H)-plane, consistent with all present experimental data, where there is a strongly first-order electroweak phase transition and where the electroweak vacuum is metastable but sufficiently long-lived. In particular we obtain absolute upper bounds on the Higgs and stop masses, m_H\lesssim 127 GeV and m_{\tilde t}\lesssim 120 GeV, implying that this scenario will be probed at the LHC.

description: Fernsehen lässt sich als eine gesellschaftliche Agentur beschreiben, die damit beschäftigt ist, soziale Differenz zu problematisieren und in spezifischer Weise evident zu machen. Doch Fernsehen ›vermittelt‹ nicht nur soziale Differenzen innerhalb von Repräsentationspolitiken und genrespezifischen Ausformulierungen. Es lässt soziale Unterscheidungen zugleich entstehen, bewirkt und ›bearbeitet‹ sie und lässt sie gesamtgesellschaftlich evident erscheinen. Dort, wo Fernsehen problematisiert wird, geht es, so zeigen die Beiträge in diesem Buch, immer auch um weitreichende sozioökonomische und politische Kämpfe, die auf gesellschaftliche Teilhabe zielen und in Form von Klassendifferenzen wirksam werden.

description: The idea that we live near the centre of a large, nonlinear void has attracted attention recently as an alternative to dark energy or modified gravity. We show that an appropriate void profile can fit both the latest cosmic microwave background and supernova data. However, this requires either a fine-tuned primordial spectrum or a Hubble rate so low as to rule these models out. We also show that measurements of the radial baryon acoustic scale can provide very strong constraints. Our results present a serious challenge to void models of acceleration.

description: Als die Sprecherin des US-Repräsentantenhauses Nancy Pelosi am 04. Februar 2020 am
Ende von US-Präsident Donald Trump’s Rede ihre Kopie der Rede zur Lage der Nation zerriss,
gingen die dabei entstandenen Bilder viral. Diese Arbeit setzt sich damit auseinander,
inwiefern dieser Akt als einer des Protests interpretiert werden kann, ob das Manuskript im
Moment dieses Akts zu einem Symbol der Trump’schen Politik wird und inwieweit der Akt
somit als Symbolsturz bzw. -angriff gedeutet werden kann. Mittels visueller Kontextanalyse
werden Denkbilder von US-amerikanischen traditionellen Medien, sowie Interpretationsarten
auf den Social Media Plattformen Instagram um Twitter analysiert. Durch diese Analyse
konnte herausgefunden werden, dass Nancy Pelosi mit diesem Akt einen inszenierten
Symbolangriff vollzogen hat.
description: When the speaker of the US-House of Representatives, Nancy Pelosi, on February 4th 2020 ripped her copy of Donald Trump’s State Of The Union Adress at the end of the speech, the pictures of this act went viral. This paper investigates, whether one can interpret this act as one of protest, if the manuscript of the speech turns into a symbol of Trump’s politics in that moment and how this act can be interpreted as an overturn or attack of/on a symbol. By applying the method of visual context analysis, the mental images of traditional US-media, as well as those of social media platforms like Instagram and Twitter are analysed. With this analysis it could be discovered that Nancy Pelosi enacted a staged attack on a symbol.
