Temp Sentry: Un Sistema di Rilevazione Dati Ambientali
Creators: name: Guerra, Alberto
Publisher: name: INFN Open Access Repository
Year: 2007

description: Il sistema di condizionamento di una sala macchine è uno dei fattori di maggiore criticità. Attualmente sono ospitate presso la sala calcolo del SICR (Servizio Impianti Calcolo e Reti) della Sezione di Roma le risorse informatiche dei gruppi di ricerca operanti in sezione e del polo GARR di Roma. Si tratta di circa 220 server, 30 sistemi di storage, 20 apparati di rete, più svariati monitor e KVM.Il gran numero di apparecchiature ha evidenziato la necessità di rilevare i dati ambientali nel tempo, impostando soglie di allarme, superate le quali deve essere segnalata la variazione di stato. Attualmente il sistema sviluppato rileva la temperatura tramite 3 sonde termiche; i dati sono riportati su grafici disponibili via Web e in caso di superamento della soglia di allarme vengono inviate email di segnalazione. Il prossimo sviluppo previsto aumenterà il numero di sonde termiche, verrà rilevata anche l'umidità e sarà integrato un sistema per l'invio di SMS.Questa nota descrive l'hardware, il programma di gestione degli allarmi e il metodo utilizzato per la pubblicazione su Web dei grafici.

description: A class of bivariate infinite series solutions of the elliptic and hyperbolic Kepler equations is described, adding to the handful of 1-D series that have been found throughout the centuries. This result is based on an iterative procedure for the analytical computation of all the higher-order partial derivatives of the eccentric anomaly with respect to the eccentricity $e$ and mean anomaly $M$ in a given base point $(e_c,M_c)$ of the $(e,M)$ plane. Explicit examples of such bivariate infinite series are provided, corresponding to different choices of $(e_c,M_c)$, and their convergence is studied numerically. In particular, the polynomials that are obtained by truncating the infinite series up to the fifth degree reach high levels of accuracy in significantly large regions of the parameter space $(e,M)$. Besides their theoretical interest, these series can be used for designing 2-D spline numerical algorithms for efficiently solving Kepler's equations for all values of the eccentricity and mean anomaly.
ROCI China and the Prospects of "Post-West" Contemporaneity
Creators: name: Gladston, Paul
Publisher: name: The Journal of Transcultural Studies
Year: 2021

description: This article reassesses the critical significance of Robert Rauschenberg’s collaboration with artisans and government institutions in the People’s Republic of China as part of the Rauschenberg Overseas Cultural Interchange (ROCI), which culminated in the exhibition ROCI China at the China Art Gallery, Beijing, in 1985. Artworks by Rauschenberg showcased in ROCI China have been internationally upheld as seminal contributions to the establishment of a cosmopolitan and technically diverse modern/contemporary art in the PRC. The works bring together Western/ized post/modernism with localized Chinese cultural thought and practice. The present article describes actions and events related to the staging of ROCI China, and then situates the exhibition in relation to an imbricating succession of modernizing artworlds particular to China during the twentieth century. In that light, a case is made for the interpretation of ROCI China as part of an extended relay of mutually constitutive transcultural interchanges between the artworlds of China, and Euro-America and other Western/ized spaces. The article thus demonstrates that the impact of ROCI China was subject to the diffractive effects of multilateral appropriations-translations and parallaxes pertaining to divergent Chinese and Western/ized discursive perspectives on the significance of art. The intersectional combination of these forces can be understood, by turns, to deconstruct the supposedly seminal standing of ROCI China, while also reinforcing a historically dominant cultural exceptionalism in the PRC, which is now amplified by the intensely interconnected and conspicuously factional condition of “post-West” contemporaneity. The article concludes by projecting ROCI China beyond this seeming paradox, as the index of a multi-dimensional non-synthetic criticality resistant to Chinese and Western authoritarianism.

“Unsettling” the Forest as a Canadian Nationalist Imaginary: Consent, Consultation, and (Re)conciliation in Leila Sujir’s Forest!
Creators: name: Sivanesan, Haema
Publisher: name: The Journal of Transcultural Studies
Year: 2021

description: Leila Sujir’s ongoing stereoscopic 3D and Virtual Reality media art project, Forest! is situated in the old growth rainforests of the South Walbran Valley of Vancouver Island, on the traditional and ancestral lands of the Pacheedaht First Nation. Taking place more than a century and a half since the settling of Vancouver Island by British colonizers, which was soon followed by successive waves of immigration by Chinese, Japanese, South Asian, and other laborers, Sujir’s project comes up against the effects and consequences of settler colonialism in the forests of Vancouver Island, and reveals the complexities and paradoxes of Canada’s mandate for (re)conciliation with Indigenous peoples. This paper explores Sujir’s process of artistic collaboration, works with a range of Indigenous, community, and artworld stakeholders, and draws on a heuristic methodology to navigate complex community and inter-racial dynamics. Sujir adopts a methodology of person-to-person conciliation as a means to mitigate Indigenous–settler tensions, developing this approach into a methodology of friendship as a means by which to secure a transparent working process that is accountable to the Pacheedaht First Nation. This in turn enables the artist to develop new transcultural understandings and a new picturing of the forest. This paper closely examines Sujir’s process in the development of two works—Forest Breath (2018) and Aerial (2019)—detailing both the difficulty and the importance of artistic collaboration in working towards an ideology of (re)conciliation with Indigenous peoples in Canada.

In this comment, we show that Eve could use a simple plan to distinguish among quantum keys, without being detected by Alice and Bob. In following, we show that our approach is not restricted to Cabello Protocol. With attention to our Eavesdropping approach, it seems that Mor's arguments for no-cloning principal for orthogonal states is not general enough to avoid eavesdropping.

Stitching Critical Citizenship during Mexico’s War on Drugs
Creators: name: Olalde, Katia
Publisher: name: The Journal of Transcultural Studies
Year: 2021

description: In this article, I focus on a set of collectively stitched handkerchiefs commemorating victims of Mexico’s “war on drugs.” I propose that these embroideries completed in relays can be conceived as the tangible manifestation of work done by collaboration networks articulated by the response of the participants to the call for a critical exercise of citizenship. I posit that the word “citizenship” can be read either as domestic citizenry, that is, as exhorting Mexican nationals to commit to the political struggle against violence and impunity; or as global citizenship, that is, as promoting a responsibility towards and a sense of interconnectedness with a common humanity. In both cases, the call for a critical exercise of citizenship expresses a concern to promote and act in accordance with an ethics of nonviolence, informed by the principles of indigenous communal polities and by the longstanding connection between embroidery and feminine moral virtue imported into New Spain during the sixteenth century.

Contested Sites, Contested Bodies: Post-3.11 Collaborations, Agency, and Metabolic Ecologies in Japanese Art
Creators: name: Deichert, Theresa
Publisher: name: The Journal of Transcultural Studies
Year: 2021

description: The cataclysmic triple disaster in Japan of March 2011 prompted Japanese artists to respond to diverse post-disaster needs. Their responses often involved collaborative practices. This paper argues that if we are to fully understand such collaborations in works of art dealing with the radioactive contamination caused by the Fukushima nuclear disaster, we must attend to collaborations with agents beyond humans. The disaster and the resulting contamination brought into focus the interconnected and interdependent ecological network of humans, non-humans, and the environment. By analyzing two artworks that include potentially radioactive foodstuffs, Flow in Red (2014) by Kyun-Chome and Does This Soup Taste Ambivalent? (2014) by United Brothers, this paper explores how artists have mobilized radioactivity, or objects penetrated by it, and collaborated with these non-human actors. Advancing from a transcultural perspective and building upon Bruno Latour’s actor-network theory, the article assumes an ecological approach to art that pushes beyond cultural categorizations and pays attention to non-human agency. Examining artworks in this way unravels post-disaster social and political concerns, such as distributions of power, anxiety over contamination, and discrimination against disaster victims.

description: Gravitational waves in the sensitivity band of ground-based detectors can be emitted by a number of astrophysical sources, including not only binary coalescences, but also individual spinning neutron stars. The most promising signals from such sources, although not yet detected, are long-lasting, quasi-monochromatic Continuous Waves (CWs). The PyFstat package provides tools to perform a range of CW data-analysis tasks. It revolves around the F-statistic, a matched-filter detection statistic for CW signals that has been one of the standard methods for LIGO-Virgo CW searches for two decades. PyFstat is built on top of established routines in LALSuite but through its more modern Python interface it enables a flexible approach to designing new search strategies. Hence, it serves a dual function of (i) making LALSuite CW functionality more easily accessible through a Python interface, thus facilitating the new user experience and, for developers, the exploratory implementation of novel methods; and (ii) providing a set of production-ready search classes for use cases not yet covered by LALSuite itself, most notably for MCMC-based followup of promising candidates from wide-parameter-space searches.

description: Nell'ambito del progetto CryoAlp è stato sviluppato e collaudato un sistema di movimentazione micrometrica a sei gradi di libertà progettato per esperimenti di microscopia e spettroscopia in alto vuoto. Le caratteristiche di questo sistema micrometrico, dimensioni compatte, ampio campo operativo unito ad alta precisione, possibilità di eseguire mappature di superfici con geometrie complesse, compatibilità con ambiente di alto vuoto, temperature di esercizio fino a -50^oC, rendono questo sistema unico nel suo genere per esperimenti non convenzionali su campioni con superfici irregolari, in condizioni di temperatura controllata in vuoto. In the framework of the CryoAlp project we developed and tested a micro-positioning system with six degrees of freedom devoted to spectromicroscopy experiments in a high-vacuum regime. The characteristics of this micrometric system: compactness, wide operating range combined to a high precision, capability to perform mapping of sample surfaces with complex geometries, compatibility with high-vacuum, operating temperatures down to {-50}^oC - make this system a unique system, tailored to specific requirements of non conventional experiments, such as those looking at samples with non homogeneous surfaces, in a controlled temperature regime in vacuum.

description: Electron density and electron momentum density, while independently tractable experimentally, bear no direct connection without going through the many-electron wave function. However, invoking a variant of the constrained-search formulation of density functional theory, we develop a general scheme (valid for arbitrary external potentials) yielding decent momentum space properties, starting exclusively from the coordinate space electron density. Numerical illustration of the scheme is provided for the closed-shell atomic systems He, Be and Ne and for $1s^1~2s^1$ singlet electronic excited state for Helium by calculating the Compton profiles and the $$ expectation values derived from given coordinate space electron densities.

description: We study the density distribution of the minimally-coupled scalar field dark energy inside a neutron star. The dark energy is considered in the hydrodynamical representation as a perfect fluid with three parameters (background density, equation of state, and effective sound speed). The neutron star matter is modeled with three unified equations of state, developed by the Brussels-Montreal group. With the calculated density distribution of the dark energy inside a neutron star (and its dependence on the dark energy parameters) we investigate how its presence impacts the macroscopic characteristics and the value of the mass limit for neutron stars. From this impact we derive the possible constrains on the effective speed of sound of dark energy with the help of maximal known masses of observed neutron stars. In this approach, we have found, that the squared effective speed of sound can not be smaller than $\sim 10^{-2}$ in units of squared speed of light.

description: We apply unsupervised learning techniques to classify the different phases of the $J_1-J_2$ antiferromagnetic Ising model on the honeycomb lattice. We construct the phase diagram of the system using convolutional autoencoders. These neural networks can detect phase transitions in the system via `anomaly detection', without the need for any label or a priori knowledge of the phases. We present different ways of training these autoencoders and we evaluate them to discriminate between distinct magnetic phases. In this process, we highlight the case of high temperature or even random training data. Finally, we analyze the capability of the autoencoder to detect the ground state degeneracy through the reconstruction error.

description: La Camera Spaziale Climatica (CSC) in allestimento ai LNF è un progetto integrato con applicazioni di fisica fondamentale e di ricaduta e trasferimento tecnologico per usi civili ed industriali  . Nella CSC, infatti, si intendono studiare sperimentalmente le caratteristiche ottiche e termiche delle componenti dei satelliti LAGEOS I e II (già operativi) e la loro evoluzione LARES (in via di realizzazione ai LNF). Lo scopo è quello di migliorare l'accuratezza della misura del trascinamento dei sistemi inerziali in Relatività Generale (effetto Lense-Thirring [1] [2]) e delle applicazioni di Geodesia. Gli elementi orbitali vengono determinati con inseguimento via laser da Terra dei satelliti (Satellite Laser Ranging, SLR). L'applicazione tecnologica più importante è il contributo fondamentale alla definizione del sistema internazionale di riferimento di posizione terrestre (ITRF, Intern. Terrestrial Reference Frame), emesso dallo IERS  (Intern. Earth Reference Service), lo standard assoluto per tutte le attività civili, industriali e scientifiche, a Terra e nello spazio, che necessitano di un sistema di riferimento assoluto.Le misure effettuate nella CSC saranno, inoltre, estremamente utili all' ottimizzazione dell'integrazione tra il GNSS (Global Navigation Satellite System) [6] ed SLR, che avrà compimento sulle costellazioni di GALILEO (Europa) e GPS-3 (USA).

description: Il Consigio di Amministrazione dell'ASI, nella sua seduta del 7/2/2008, ha individuato le cinque proposte, nell'ambito del Bando Piccole Missioni, di cui verrà finanziato lo studio di Fase A, ovvero lo studio di fattibilità preliminare alla scelta delle due missioni che verranno lanciate entro il 2014. Una di queste cinque missioni è MAGIA (Missione Altimetrica Gravimetrica geochimica Italiana lunAre), di cui il Principal Investigator è la Prof. A. Coradini (INAF-IFSI) e il Prime Industriale è Rheinmetall Italia S.p.A. La missione si propone di rispondere ad alcune delle questioni di maggiore importanza per lo studio della Luna quali la struttura interna, elemento necessario per comprendere l'origine e la formazione, la ricerca di evidenze di processi di differenziazione che devono aver caratterizzato la parte iniziale della formazione e la correlazione con la successiva fase dominata dalla craterizzazione della superficie. Al momento, i dati geochimici e mineralogici da telerilevamento lunare, utili per raccordare le analisi dei campioni di rocce prelevate in-situ ad aree del satellite più vaste, sono disponibili solo per la "near side". Inoltre anche le missioni più recenti (Clementine, SMART-1, Lunar Prospector) non avevano a bordo strumenti in grado di effettuare un'analisi mineralogica accurata. MAGIA si propone inoltre una precisa caratterizzazione del campo gravitazionale lunare, ed ad un'accurata misura del suo stato rotazionale. Questi temi sono tutti strettamente legati tra loro concorrendo, infatti, a migliorare la comprensione dell'origine ed evoluzione della Luna. Inoltre, MAGIA mostrerà come si possa utilizzare una piattaforma in orbita circumlunare al fine di ottenere misure di fisica fondamentale, quali un miglioramento delle misura del redshift gravitazionale, una "precursor mission" per la proposta di Lunar Laser Ranging di seconda generazione, MoonLIGHT, ed un potenziale ulteriore miglioramento dei test delle Relatività Generale grazie ad una misura indipendente della posizione del selenocentro rispetto a Terra. Questo Report descrive il pacchetto di Fisica Fondamentale della proposta MAGIA.

description: To search for optical counterparts to gravitational waves, it is crucial to develop an efficient follow-up method that allows for both a quick telescopic scan of the event localization region and search through the resulting image data for plausible optical transients. We present a method to detect these transients based on an artificial neural network. We describe the architecture of two networks capable of comparing images of the same part of the sky taken by different telescopes. One image corresponds to the epoch in which a potential transient could exist; the other is a reference image of an earlier epoch. We use data obtained by the Dr. Cristina V. Torres Memorial Astronomical Observatory and archival reference images from the Sloan Digital Sky Survey. We trained a convolutional neural network and a dense layer network on simulated source samples and tested the trained networks on samples created from real image data. Autonomous detection methods replace the standard process of detecting transients, which is normally achieved by source extraction of a difference image followed by human inspection of the detected candidates. Replacing the human inspection component with an entirely autonomous method would allow for a rapid and automatic follow-up of interesting targets of opportunity. The method will be further tested on telescopes participating in the Transient Optical Robotic Observatory of the South Collaboration.

description: This work is proposing some examples of a possible use of the geometry based on rectangular triangles, the varatio, in the planning of Roman towns. It is known that the planning of them is based on the centuriation, a grid of parallel and perpendicular streets, where the two main axes are the Decumanus and the Cardo. The ratio of the catheti of the rectangular triangles gives the angle the Decumanus is forming with the east-west direction.
Stabilizing the Edge: Southeastern and Mid-Atlantic Shorescapes Facing Sea-level Rise

Publisher: name: Columbia Journal of Environmental Law
Year: 2021

description: Ecologically fragile coasts face increasing pressures from economic development, population growth, hurricanes, extreme weather events, and sea-level rise. This Article addresses the last of these threats, focusing on shoreline stabilization law and policy. “Living shorelines” and similar nature-based approaches are often better alternatives to stabilize shorelines and reduce dangerous erosion than traditional hard “armoring” practices such as bulkheads and seawalls. Shoreline armoring is also closely associated with habitat loss in intertidal and subtidal areas, affecting fisheries’ production, water quality, and other valuable ecosystem services. Adapting shoreline stabilization infrastructure and approaches to sea-level rise will require measures that improve federal, state, and local governance mechanisms; promote nature-based management practices; and change property owner behavior that affects coastal areas. This Article analyzes ocean-facing and estuarine protection laws in the Southeast and Mid-Atlantic states to identify how governance mechanisms could better integrate sea-level rise into coastal management practices and decision-making, concentrating in particular on policies designed to reduce erosion and flooding. Our research revealed important distinctions between how we manage ocean-facing and estuarine-facing shorelines, as well as a wide variety of values and interests driving these differences. A regulatory system more strongly connected by science to the applicable natural systems is possible and desirable. To our knowledge, no such comprehensive overview or comparison of these shorescape protection, setback, and stabilization laws currently exists. Ultimately, the Article fills an important research gap in the existing climate change and coastal management literature, as it sets the stage for incorporating interdisciplinary findings from coastal science and social science research with legal and policy mechanisms to inform coastal zone management.

description: Noncommutative geometry is used to study the local geometry of ultrametric spaces and the geometry of trees at infinity. Connes's example of the noncommutative space of Penrose tilings is interpreted as a non-Hausdorff orbit space of a compact, ultrametric space under the action of its local isometry group. This is generalized to compact, locally rigid, ultrametric spaces. The local isometry types and the local similarity types in those spaces can be analyzed using groupoid C^*-algebras. The concept of a locally rigid action of a countable group Γon a compact, ultrametric space by local similarities is introduced. It is proved that there is a faithful unitary representation of Γinto the germ groupoid C^*-algebra of the action. The prototypical example is the standard action of Thompson's group V on the ultrametric Cantor set. In this case, the C^*-algebra is the Cuntz algebra O_2 and representations originally due to Birget and Nekrashevych are recovered. End spaces of trees are sources of ultrametric spaces. Some connections are made between locally rigid, ultrametric spaces and a concept in the theory of tree lattices of Bass and Lubotzky.

description: We employ electric circuit networks to study topological states of matter in non-Hermitian systems enriched by parity-time symmetry $\mathcal{PT}$ and chiral symmetry anti-$\mathcal{PT}$ ($\mathcal{APT}$). The topological structure manifests itself in the complex admittance bands which yields excellent measurability and signal to noise ratio. We analyze the impact of $\mathcal{PT}$ symmetric gain and loss on localized edge and defect states in a non-Hermitian Su--Schrieffer--Heeger (SSH) circuit. We realize all three symmetry phases of the system, including the $\mathcal{APT}$ symmetric regime that occurs at large gain and loss. We measure the admittance spectrum and eigenstates for arbitrary boundary conditions, which allows us to resolve not only topological edge states, but also a novel $\mathcal{PT}$ symmetric $\mathbb{Z}_2$ invariant of the bulk. We discover the distinct properties of topological edge states and defect states in the phase diagram. In the regime that is not $\mathcal{PT}$ symmetric, the topological defect state disappears and only reemerges when $\mathcal{APT}$ symmetry is reached, while the topological edge states always prevail and only experience a shift in eigenvalue. Our findings unveil a future route for topological defect engineering and tuning in non-Hermitian systems of arbitrary dimension.

description: We present a simple method for calculating the energies and the widths of quasiparticle resonant states. The method is based on BCS equations solved in the Berggren representation. In this representation the quasiparticle resonances are associated to the Gamow states of the mean field. The method is illustrated for the case of neutron-rich nuclei $^{20-22}$O and $^{84}$Ni. It is shown that the contribution of the continuum coupling to the pairing correlations is small and largely dominated by a few resonant states close to the continuum threshold.

Cosmic infrared background from Population III stars and its effect on spectra of high-z gamma-ray bursts

description: We discuss the contribution of Population III stars to the near-IR (NIR) cosmic infrared background (CIB) and its effect on spectra of high-$z$ high-energy gamma-ray bursts (GRBs). It is shown that if Population III were massive stars, the claimed NIR CIB excess will be reproduced if only ~ 4+/-2% of all baryons went through these stars. Regardless of the precise value of the NIR CIB produced by them, they would leave enough photons to provide a large optical depth for high-energy photons from high-z GRBs. Observations of such GRBs are expected following the planned launch of NASA's GLAST mission. The presence or absence of such damping in the spectra of high-$z$ GRBs will then provide important information on the emissions from the Population III. The location of this cutoff may also serve as an indicator of the GRB's redshift.

QSP, optimization software for preform tailoring
Creators: name: Guillon, Damien
Publisher: name: Zenodo
Year: 2018
Subjects: Thermoplastic composite, design, optimization

description: QSP can produce complex-shaped parts with a production line pulse-time of 40-90 seconds. For example, using QSP, an omega-shaped profile molded into an L-shaped beam integrates 13 patches of 1.5-, 2- and 3-millimeter thick organosheet (woven fabric thermoplastic prepreg) and UD tape into a 6-millimeter-thick part with a cycle time of less than 77 seconds per part. However, to take advantage of automation technology such as QSP, engineers must develop design and optimization methods that can evaluate many theoretical combinations of partial plies and the corresponding variation in the number, thickness, position and composition of plies (for example, reinforcement type and fiber orientation). With this in mind, Cetim has combined its experience in composites structural analysis, nondestructive testing (NDT) and manufacturing with the expertise of ONERA (The French Aerospace Lab) in advanced optimization methods used for years in the aerospace industry. The result is QSD, a tool now available in Altair Engineering’s (Troy, Mich., U.S.) HyperWorks computer-aided engineering (CAE) software. It is basically an optimization add-on that helps to design composite parts made using tape- and organosheet-based processes and to control their cost, including how to reuse production scrap for zero-waste, closed-loop manufacturing.
The cooling-down central star of the planetary nebula SwSt\,1: a late thermal pulse in a massive post-AGB star?

description: SwSt 1 (PN G001.5-06.7) is a bright and compact planetary nebula containing a late [WC]-type central star. Previous studies suggested that the nebular and stellar lines are slowly changing with time. We studied new and archival optical and ultraviolet spectra of the object. The [OIII] 4959 and 5007 A to $\mathrm{H}β$ line flux ratios decreased between about 1976 and 1997/2015. The stellar spectrum also shows changes between these epochs. We modeled the stellar and nebular spectra observed at different epochs. The analyses indicate a drop of the stellar temperature from about 42 kK to 40.5 kK between 1976 and 1993. We do not detect significant changes between 1993 and 2015. The observations show that the star performed a loop in the H-R diagram. This is possible when a shell source is activated during its post-AGB evolution. We infer that a late thermal pulse (LTP) experienced by a massive post-AGB star can explain the evolution of the central star. Such a star does not expand significantly as the result of the LTP and does not became a born-again red giant. However, the released energy can remove the tiny H envelope of the star.

title: Russo-Ukrainian War: The Political Economy of the Present Balance of Forces
Creators: name: Cooper, Luke
Publisher: name: University of Edinburgh, LSE CCRG
Year: 2025
Subjects: subject: Ukraine

description: This paper examines the evolving political economy of the Russo-Ukrainian War, arguing that despite its asymmetric nature, the conflict has become more balanced due to Ukraine’s institutional resilience and consistent financial support from allies. Neither side currently has a viable path to total victory. Both economies have adopted forms of military Keynesianism, though in distinct ways shaped by regime type and external dependencies: Ukraine on allied funding, Russia on volatile oil rents. Ukraine has secured financing until 2027 and maintained monetary stability, while Russia faces growing economic risks, including a potential credit crunch and balance of payments crisis. War has reshaped both states’ capacity for autonomous organisation, central to mobilising resources and restructuring their economies. As global geopolitics fragment and protectionism rises, the prospects for peace are increasingly defined by economic pressures and shifting alliances. A ceasefire, if reached, is likely to be unstable, with Russia potentially maintaining a militarised economy. Ukraine, meanwhile, has shifted its focus from military breakthroughs to securing long-term security guarantees. The outcome of negotiations will hinge not only on military dynamics but also on the internal strains shaping each regime’s strategic calculus.
Anthropocene Accountability Litigation: Confronting Common Enemies to Promote a Just Transition
Creators: name: Abate, Randall
Publisher: name: Columbia Journal of Environmental Law
Year: 2021

description: This article offers a new perspective in the quest for climate justice. Myriad accountability lawsuits in the U.S. have been filed against the fossil fuel and industrial animal agriculture industries in the past few years, but these efforts have proceeded without coordination between the environmental and animal law fields. There has been no scholarly inquiry that unites the efforts to seek relief from “common enemies” for exacerbating the climate change crisis while profiting from their operations. The article first reviews the climate change impacts from the fossil fuel and industrial animal agriculture industries and examines how federal regulatory gaps and subsidies enable and exacerbate the climate change impacts from these industries. It then reviews legal theories in common law accountability litigation against these industries that seek damages for the harms these industries cause to public health and welfare, the environment, and animals. The article proposes that accountability litigation against the fossil fuel and industrial animal agriculture industries can facilitate a transition away from reliance on fossil fuels and factory farms to more sustainable alternatives. Positive outcomes from several related contexts including tobacco litigation, the phaseout of harmful substances in environmental regulation, and the COVID-19 crisis support the urgent need for this “just transition.”

Changes in aboriginal property rights : a chronological account of land use practices in the Lil’Wat Nation
Creators: name: Nemoto, Akihiko
Publisher: name: University of British Columbia
Year: 2009

description: This study deals with the changing dynamics of land use systems in an aboriginal community of British Columbia, namely the Lil'wat Nation, by employing the concept of property as an analytical tool. The focus on the concept of property clarifies the role played by the authority and institutions as regulators and decision-making factors in land use management. The description of the relationship between property and various transitions in aboriginal life constitutes the main contribution of this research project. The methodology used in this descriptive study is a combination of the participantobserver method and archival data collection. Issues around authority are discussed in terms of the power relationship between Canada and the Lil'wat Nation. Several historical events explain the way in which political and economic imperatives have shaped the relationship between the Lil'wat Nation and Canada, as well as the internal power relationship within the aboriginal community. It is found that the rapid and important changes in the decision-making situation (i.e., context of institution change) have significantly affected the land use projects on reserve grounds. Those changes include: high rate of population growth, extension of a money economy through forestry and agricultural activities, and exercise of various outside interests on reserve lands. Also, it is found that a number of governmental initiatives created and perpetuated a state of dependency and dissension among the aboriginal community. Since land use practices cannot be viewed in isolation, this study emphasizes the importance of political reform and sharing of authority. Also, some strategies for Lil'wat's selfdetermination are identified and the urgency to develop community-based economic projects is stressed.

Uprooting Authoritarianism
Creators: name: Powell, John A.
name: Toppin, Eloy
Publisher: name: Columbia Journal of Race and Law
Year: 2021

description: Authoritarianism is on the rise globally, threatening democratic society and ushering in an era of extreme division. Most analyses and proposals for challenging authoritarianism leave intact the underlying foundations that give rise to this social phenomenon because they rely on a decontextualized intergroup dynamic theory. This Article argues that any analysis that neglects the impact of dominance as a legitimizing characteristic of in-group formation and identity construction based on dominant in-group membership will fall short of understanding the surge of authoritarianism. In the West, and the United States in particular, this dominant ingroup takes shape around the ideology and social force of whiteness. Whiteness, as the bonding element of a dominant identity-based in-group, compels narrow identities and exclusive group membership. It also makes promises of social gain and advantage to those constituted as white, the erosion of which is the source of the authoritarian uprising in the United States. This Article discusses the establishment of the Western metanarrative, and whiteness’s relation to it, and then advances a strategy to replace it with a more inclusive narrative of deep belonging, offering guidance to the social justice movement in its work toward this end.

description: We report the engineering of air-voids embedded in GaAs-based photonic crystal surface emitting lasers realised by metalorganic vapour-phase epitaxy regrowth. Two distinct void geometries are obtained by modifying the photonic crystal grating profile within the reactor prior to regrowth. The mechanism of void formation is inferred from scanning transmission electron microscopy analysis, with the evolution of the growth front illustrated though the use of an AlAs/GaAs superlattice structure. Competition between rapid lateral growth of the (100) surface and slow diffusion across higher index planes is exploited in order to increase void volume, leading to an order of magnitude reduction in threshold current and an increase in output power through an increase in the associated grating coupling strength.
