description: Housing affordability and access is one of the most important social and political issues affecting America today. Many Americans are left with having to live with multiple roommates, move back home with family, or becoming homeless. Ground zero for America’s housing crisis is San Francisco, California. Located on the Northern California coastline, San Francisco is home to the nation’s highest rent and home prices with hardly any site of reversal. At its core, due to the rampant displacement, lack of housing security, and inability for many to obtain housing, the San Francisco housing crisis is a human rights issue that needs solving. Over the years, experts have discussed various ideas of how to address the crisis in the city. Some groups will advocate for YIMBY-ism (“Yes In My Backyard”) over NIMBY-ism (“No In My Backyard”) because they believe that in order to solve the crisis we need to build more housing of any type (luxury, market rate, and affordable) to meet the crisis head-on. Tenants unions are advocating for a proliferation of affordable housing. Policy makers are devising plans for reforming zoning laws, transit-oriented housing, and rethinking older policies that could lead to better housing access for all. This thesis will explore solutions to the human rights issue that is the San Francisco housing crisis. The topics that I will discuss in pursuit of finding the solution to the housing crisis facing San Francisco will include examining policies that have hindered or usurped the human right to housing, contemporary ideas from leaders in the field on how to address it, and international soft law on the human right to housing. This thesis will conclude that the solution to the state’s housing crisis will require a mixture of policy innovations, transit solutions, density and increase in housing stock, and a need for more mixed-income housing to address the city’s housing crisis. In short, I am focusing on housing as a human right because adequate shelter should not be considered a luxury.

description: The $L_α$ phase of lipid bilayers is a fluid self-assembled state, key to the formulation of cosmetics, detergents and pharmaceutics. Despite having been extensively scrutinized in self-assembled phospholipid or surfactant bilayers, the formation of a fluid $L_α$ state has defied understanding in mixtures of fatty alcohols, surfactants and water, where is viewed as the essential step for the preparation of creamy dispersions. Here, atomistic molecular dynamics simulations show the existence of a fluid bilayer in aqueous mixtures of cetyl (C$_{16}$OH) and stearyl (C$_{18}$OH) alcohols, and cetyl-trimethylammonium chloride (CTAC). These simulated bilayer systems display not only a rich temperature phase diagram with many of the features seen in experiments but carry also the unambigous signature of fluid bilayer behavior.

description: The von Neumann entropy production for a quantum mechanical kicked rotor coupled to a thermal environment is calculated. This rate of entropy increase is shown to be a good criterion to distinguish between quantum mechanical counterparts of chaotic and regular classical motion. We show that for high temperatures the entropy production rate increases linearly with the Kolmogorov-Sinai entropy of the classical system. However, for lower temperatures we also show that there are fluctuations in this linear behaviour due to dynamical localization.

description: We discuss the relation between the emergence of new phases with broken symmetry within the framework of simple models of biopolymers. We start with a classic model for a chain molecule of spherical beads tethered together, with the steric constraint that non-consecutive beads cannot overlap, and with a pairwise attractive square well potential accounting for the hydrophobic effect and promoting compaction. We then discuss the consequences of the successive breaking of spurious symmetries. First, we allow the partial interpenetration of consecutive beads. In addition to the standard high temperature coil phase and the low temperature collapsed phase, this results in a new class of marginally compact ground states comprising conformations reminiscent of $α$-helices and $β$-sheets, the building blocks of the native states of globular proteins. We then discuss the effect of a further symmetry breaking of the cylindrical symmetry on attaching a side-sphere to the backbone beads along the negative normal of the chain, to mimic the presence of side chains in real proteins. This leads to the emergence of a novel phase within the previously obtained marginally compact phase, with the appearance of more complex secondary structure assemblies. The potential importance of this new phase in the \textit{de novo} design of self-assembled peptides is highlighted.

Un episodio delle relazioni commerciali tra Gran Bretagna e Regno delle Due Sicilie: “la questione degli oli napoletani”
Creators: name: Pintaudi, Vincenzo
Publisher: name: Humanities
Year: 2021

description: Nella ricostruzione delle relazioni commerciali tra la Gran Bretagna e il Regno delle Due Sicilie, nella fase cruciale dello sviluppo economico-industriale della prima metà dell’Ottocento, emerge il tentativo del governo napoletano di avviare una propria politica economica indipendente dalla supremazia commerciale britannica, sorta all’indomani della Restaurazione. La svolta protezionistica degli anni Venti surriscaldava il clima diplomatico tra i due paesi, avviando rappresaglie da ambo le parti. Ma sarà il commercio dell’olio d’oliva napoletano, il maggior prodotto di esportazione del Mezzogiorno, a scatenare le ritorsioni inglesi. Il governo borbonico dimostrava con questo episodio di voler proseguire ad ogni costo il suo obiettivo di indipedenza economico-politica, ricercando e trovando nuovi sbocchi al prodotto fondamentale per l’economia dell’intero Regno, soprattutto attraverso i porti franchi del Mediterraneo. Il conflitto commerciale ingaggiato con la Gran Bretagna, in cui si inseriva anche quello più noto degli zolfi, si trascinerà per oltre un decennio, influenzando le relazioni diplomatiche tra i due paesi e si concluderà solo a seguito della svolta politico-commerciale del nuovo governo di sua Maestà Britannica degli anni Quaranta. Il Primo Ministro Robert Peel avvierà una nuova stagione nelle relazioni commerciali con tutte le “Maggiori Potenze” europee, basate sul libero scambio e la conseguente riduzione dei dazi doganali, determinando la stipula di un serie di trattati di commercio, in cui si inserirà anche la “Media Potenza” borbonica.

description: La rarefazione della pratica della vendetta è convenzionalmente ritenuta un marcatore della modernità, ma siamo davvero così convinti della sua estinzione? Nell’immaginario moderno al termine “vendetta” sono spesso associate connotazioni tipicamente negative: violenza incontrollata e intrinsecamente illegittima propria di popolazioni barbare, esercizio arbitrario della violenza tra privati, antitesi perfetta del diritto e della stessa giuridicità. In realtà, ad un’indagine più approfondita, essa non solo si rivela realtà meno negativa di quanto appaia a prima vista, ma si ritrova ancora diffusamente presente nelle pieghe dei moderni sistemi giuridici.

description: Raccontare e raccontarsi, un bisogno insopprimibile dell’uomo da sempre, ad ogni latitudine culturale e storica. Tutto ha inizio dagli incerti fonemi vocali dell’uomo arcaico, nell'area del presemantico, dai suoni disarticolati e vocalizzi referenziali e segnaletici, nell’accezione anche di genocanto, quali ‘vagiti dell’anima’ prima del canto, ad imitazione dei versi sonori della natura e delle sue creature, uniti alle incisioni rupestri. E poi, ecco la trasfigurazione dei suoni umani in un codice linguistico riconoscibile, identitario, condiviso, in grado di formalizzare e rappresentare il proprio sguardo sul mondo e sugli uomini.

description: Questa documentatissima monografia offre l’opportunità di entrare in un mondo che si tende a pensare morto, semmai ristretto, residuale, inattuale perché, assieme a tante altre “cose”, travolto dall’ineluttabile “modernità” che, scrissero bene Jean Baudrillard (1991) e Paul Connerton (2009), troppo ha dimenticato e ancora fa dimenticare. Se ciò vale per la netta riduzione che piattaforme, schermi, scrolling hanno, in un modo o nell’altro, dato alla Storia, alle nostre capacità e possibilità di memoria, forse vale un po’ meno per la Magia; se non altro per una “informatica” che, per i frequenti e incomprensibili malfunzionamenti, si ritrova spesso ad essere vissuta e accettata come “informagica”. Qui, infatti, è l’attualità di un mondo magico, mantico, divinatorio, oracolare, sovraumano tanto segreto e impenetrabile quanto vivissimo nelle tecniche, nelle ritualità, nei linguaggi e nelle poetiche che possiamo conoscere da vicino, grazie al lavoro etnografico di lunghissima durata che Marilena Maffei, dai primi anni Ottanta a oggi, ha condotto nelle Isole Eolie. Contesto contadino, pastorale e marinaro al tempo stesso, cui l’antropologa culturale ha dedicato quasi l’intera sua attività di ricerca raccogliendone e indagandone narrazioni, miti, fiabe, immagini, immaginari, culti, canti in una serie di preziosissimi, straordinari studi: ricordo solo Capelli di serpe (1995), Donne di mare (2013), il recente La danza delle streghe.

Armando Morbiato L’incanto del viaggiatore. Diari (1957-1967) e ricordi di un emigrante A cura di Luciano Morbiato, prefazione di Francesco Vallerani Il Poligrafo, Padova 2020, pp. 321

description: L’incanto del viaggiatore è il diario di Armando Morbiato (Albino per amici e familiari) che riporta ricordi di un emigrante, per certi aspetti simili a quelli di milioni di ragazzi italiani sin dall’Ottocento coinvolti nel lasciare l’Italia per andare all’estero in cerca di fortuna. Condizioni e narrazioni oggi note alla nutrita compagine di storici, sociologi, antropologi che le hanno sviscerate in una sterminata serie di studi critici. Tuttavia, sin dalle prime pagine, davvero diversi, particolari, originali, «incantevoli» risaltano i toni con cui Albino racconta la sua vicenda familiare, l’infanzia e l’adolescenza a Camin, tra contadini, artigiani, bottegai e le prime fabbriche tessili, mobili, calzaturiere del Padovano, e quindi il complesso delle vicissitudini che, nel 1957, l’avrebbero portato, a poco più di vent’anni, a intraprendere la mitica traversata dal porto di Genova fino all’Australia. Toni diversi da quelli dell’emigrazione italiana perché, a sostenerli, non è solo il “dramma” migratorio che pur vide Albino, sull’altro emisfero, valentissimo carpeniere e falegname in un amplissimo ventaglio di opportunità lavorative ma, anche e soprattutto, per il progressivo, amorevole appassionamento al viaggio che l’emigrante matura già in quella provincia segnata dalla miseria, dalla precarietà, dal fascismo, dalle lotte sociali, dalla guerra e dalla Resistenza, dalla sopravvivenza e da una indomita volontà di ripresa. Insomma sin dalle prime pagine del suo racconto autobiografico – quando, ad esempio, ricorda l’apprendistato dall’intagliatore Campaneo fino a Noventa, da Cacco, in quell’industriosa società popolare veneta; le prime, affascinanti gite in bici e quelle in corriera che i patronati nel dopoguerra organizzavano per i ragazzi poveri, fino all’Anno Santo del 1950 e al pellegrinaggio a Roma dove nell’arco di Tito o nell’obelisco di Axum scoprì la storia come «oggetto concreto» - rintracciamo l’insieme delle variabili che, di lì a poco, tra il 1957 e il 1967, avrebbero fatto di Albino il protagonista di un percorso davvero raro e, per noi, pieno di spunti antropologici di riflessione.

description: This paper presents Cramér-Rao Lower Bound (CRLB) for the complex-valued Blind Source Extraction (BSE) problem based on the assumption that the target signal is independent of the other signals. Two instantaneous mixing models are considered. First, we consider the standard determined mixing model used in Independent Component Analysis (ICA) where the mixing matrix is square and non-singular and the number of the latent sources is the same as that of the observed signals. The CRLB for Independent Component Extraction (ICE) where the mixing matrix is re-parameterized in order to extract only one independent target source is computed. The target source is assumed to be non-Gaussian or non-circular Gaussian while the other signals (background) are circular Gaussian or non-Gaussian. The results confirm some previous observations known for the real domain and bring new results for the complex domain. Also, the CRLB for ICE is shown to coincide with that for ICA when the non-Gaussianity of background is taken into account. %unless the assumed sources' distributions are misspecified. Second, we extend the CRLB analysis to piecewise determined mixing models. Here, the observed signals are assumed to obey the determined mixing model within short blocks where the mixing matrices can be varying from block to block. However, either the mixing vector or the separating vector corresponding to the target source is assumed to be constant across the blocks. The CRLBs for the parameters of these models bring new performance bounds for the BSE problem.

I fenomeni possono essere analizzati in prospettiva diversa rispetto agli effetti, di qui l’interdisciplinarietà e il ricorso a più ambiti da parte del discorso storico.

description: We analyze two-component spatial optical vortex solitons supported by parametric wave mixing processes in a nonlinear bulk medium. We study two distinct cases of such localised waves, namely, parametric vortex solitons due to phase-matched second-harmonic generation in an optical medium with competing quadratic and cubic nonlinear response, and vortex solitons in the presence of third-harmonic generation in a cubic medium. We find, analytically and numerically, the structure of two-component vortex solitons, and also investigate modulational instability of their plane-wave background. In particular, we predict and analyze in detail novel types of vortex solitons, a `halo-vortex', consisting of a two-component vortex core surrounded by a bright ring of its harmonic field, and a `ring-vortex' soliton which is a vortex in a harmonic field that guides a ring-like localized mode of the fundamental-frequency field.

description: In optical belt sorting, accurate predictions of the bulk material particles’ motions are required for high-quality results. By implementing a multitarget tracker tailored to the scenario and deriving novel motion models, the predictions are greatly enhanced. The tracker’s reliability is improved by also considering the particles’ orientations. To this end, new estimators for directional quantities based on orthogonal basis functions are presented and shown to outperform the state of the art.
Circularly Symmetric Light Waves: An Overview
Creators: name: Cagliero, Andrea
Publisher: name: arXiv
Year: 2019
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Orbital Angular Momentum (OAM) waves were first recognized as those specific vortex solutions of the paraxial Helmholtz equation for which the orbital contribution to the total angular momentum of the beam yields an integer multiple of $\hbar$ along the propagation direction. However, this class of solutions can be generalized to include more sophisticated vector vortex waves with coupled polarization and spatial complexity, that are eigenfunctions of the third component of the angular momentum operator. In this work, a rigorous framework is proposed for the analysis of all the possible families of vortex solutions to the homogeneous Helmholtz equation. Both the scalar and vector cases are studied in depth, making use of an operator approach which emphasizes their intimate connection with the two-dimensional rotation group. Furthermore, a special focus is given to the characterization of the propagation properties of the most popular families of paraxial OAM beams.

Evolution equations for special Lagrangian 3-folds in C^3

Publisher: name: arXiv
Year: 2000
Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: This is the third in a series of papers constructing explicit examples of special Lagrangian submanifolds in C^m. The previous paper in the series, math.DG/0008155, defined the idea of evolution data, which includes an (m-1)-submanifold P in R^n, and constructed a family of special Lagrangian m-folds N in C^m, which are swept out by the image of P under a 1-parameter family of linear or affine maps phi_t : R^n -> C^m, satisfying a first-order o.d.e. in t. In this paper we use the same idea to construct special Lagrangian 3-folds in C^3. We find a 1-1 correspondence between sets of evolution data with m=3 and homogeneous symplectic 2-manifolds P. This enables us to write down several interesting sets of evolution data, and so to construct corresponding families of special Lagrangian 3-folds in C^3. Our main results are a number of new families of special Lagrangian 3-folds in C^3, which we write very explicitly in parametric form. Generically these are nonsingular as immersed 3-submanifolds, and diffeomorphic to R^3 or S^1 x R^2. Some of the 3-folds are singular, and we describe their singularities, which we believe are of a new kind. We hope these 3-folds will be helpful in understanding singularities of compact special Lagrangian 3-folds in Calabi-Yau 3-folds. This will be important in resolving the SYZ conjecture in Mirror Symmetry.

The model applies to a large spectrum of competing groups: smoker-non smoker war, epidemic spreading, opinion formation, competition for industrial standards and species evolution. In the last case, it provides a new explanation for punctuated equilibria.

The Challenges to Improving Public Services and Judicial Operations: A unique balance between pursuing justice and public service in Indonesia
Creators: name: Mustafa, C
Publisher: name: Zenodo
Year: 2021

description: This chapter explores judicial perspectives on sentencing minor drug offenders in Indonesia. As a basis for the framework for this study, a concept of Goffman on dramaturgy was used to explain the dramaturgical competence of the panel judges in their attempts to show accountability to their audiences (i.e., the sphere of politics, the public, and religion). Conceptualisation of this study stems from this author former self-identity as a judge but also from the author biography since the author more familiar with the practical pressure and challenges of lower court judges. This chapter contributes to knowledge by considering that the judicial awareness of the issues surrounding justice and public acceptance led to the situation where they were attempting to present a unique balance between pursuing justice and public service.

description: We propose an algorithm for low Mach number reacting flows subjected to electric field that includes the chemical production and transport of charged species. This work is an extension of a multi-implicit spectral deferred correction (MISDC) algorithm designed to advance the conservation equations in time at scales associated with advective transport. The fast and nontrivial interactions of electrons with the electric field are treated implicitly using a Jacobian-Free Newton Krylov approach for which a preconditioning strategy is developed. Within the MISDC framework, this enables a close and stable coupling of diffusion, reactions and dielectric relaxation terms with advective transport and is shown to exhibit second-order convergence in space and time. The algorithm is then applied to a series of steady and unsteady problems to demonstrate its capability and stability. Although developed in a one-dimensional case, the algorithmic ingredients are carefully designed to be amenable to multidimensional applications.

The School Library as an Other Space: A Case Study into Literacy and Identity

Year: 2018
Subjects: Education

School libraries

description: This study builds on research conducted in classrooms by proposing that literacy happens in a range of school spaces that educational research has traditionally left unattended, such as lunchrooms, hallways, and libraries. Libraries are one space, of many, in schools where literacy “happens,” despite the paucity of information about this complex space. This study explored the library as situated within a disagreement about how libraries should be utilized—either as democratic sites that provide access to a range of texts, or as sites of direct instruction in standards-aligned informational literacy.
      Informed by a spatial framework, this study investigated one school library to trace which literacy practices circulated in the space through observations, spatial maps, semi-structured interviews, and artifact analysis. Findings included the library functioning as a liminal space, where competing ideas about literacy circulated. Focal students demonstrated dominant notions of what “counted” as literacy, in that they engaged in discourses that were privileged within established conceptions of schooling. However, there were also pockets of playfulness, where the space began to “crack” and gave way to a construction that was fluid, interrupting expected literacy practices.
      In a context where classrooms continue to become constrained, alongside reduced funding for library programs, the diversity of literacy experiences that students can encounter decreases. Discovering what is possible in one space can offer fruitful discussion around the potential of school libraries, and other spaces for literacy, to strengthen literacy experiences in schools for our students who are most implicated by narrow definitions of literacy.

description: With the accumulation of big data of CME observations by coronagraphs, automatic detection and tracking of CMEs has proven to be crucial. The excellent performance of convolutional neural network in image classification, object detection and other computer vision tasks motivates us to apply it to CME detection and tracking as well. We have developed a new tool for CME Automatic detection and tracking with MachinE Learning (CAMEL) techniques. The system is a three-module pipeline. It is first a supervised image classification problem. We solve it by training a neural network LeNet with training labels obtained from an existing CME catalog. Those images containing CME structures are flagged as CME images. Next, to identify the CME region in each CME-flagged image, we use deep descriptor transforming to localize the common object in an image set. A following step is to apply the graph cut technique to finely tune the detected CME region. To track the CME in an image sequence, the binary images with detected CME pixels are converted from cartesian to polar coordinate. A CME event is labeled if it can move in at least two frames and reach the edge of coronagraph field of view. For each event, a few fundamental parameters are derived. The results of four representative CMEs with various characteristics are presented and compared with those from four existing automatic and manual catalogs. We find that CAMEL can detect more complete and weaker structures, and has better performance to catch a CME as early as possible.

description: We present and analyze experimental results on the dynamics of hydrothermal waves occuring in a laterally-heated fluid layer. We argue that the large-scale modulations of the waves are governed by a one-dimensional complex Ginzburg-Landau equation (CGLE). We determine quantitatively all the coefficients of this amplitude equation using the localized amplitude holes observed in the experiment, which we show to be well described as Bekki-Nozaki hole solutions of the CGLE.

description: This dissertation reorients the study of British modernism towards the ocean by uncovering modernism’s engagement with a set of ideas about the historical significance of the sea that I term “maritime foundationalism.” A key component of late nineteenth- and early twentieth-century British nationalism and imperialism, maritime foundationalism held that British history and identity were fundamentally maritime and that the sea, in turn, propelled Britain’s historical development and the course of history in general. Reading works by Rudyard Kipling, Joseph Conrad, Virginia Woolf, and T. S. Eliot alongside contemporary historical, geographical, and scientific texts, I trace how British modernism developed by incorporating, modifying, and contesting this pervasive maritime-historical ideology. Even as modernist works build on notions of the sea as the foundation of the empire and conveyer of its history, they also disrupt these notions by representing the sea in more unsettling ways, as a testament to the dark sides of maritime-imperial history or an element that threatens to engulf history altogether. Each of my chapters details the literary effects of this interaction of maritime foundationalism and more melancholy conceptions of the sea’s historicity at key points in the intertwined histories of modernism and empire between the 1890s and the 1940s. “The Sea Has Many Voices” thus shows how competing constructions of the sea shape modernism’s historical imagination—the way it defines its present and situates it in relationship to the past.

description: We propose an electro-optic approach for transparent optical networking, in which frequency channels are actively transformed into any desired mapping in a wavelength-multiplexed environment. Based on electro-optic phase modulators and Fourier-transform pulse shapers, our all-optical frequency processor (AFP) is examined numerically for the specific operations of frequency channel hopping and broadcasting, and found capable of implementing these transformations with favorable component requirements. Extending our analysis via a mutual-information--based metric for system optimization, we show how to optimize transformation performance under limited resources in a classical context, contrasting the results with those found using metrics motivated by quantum information, such as fidelity and success probability. Given its compatibility with on-chip implementation, as well as elimination of optical-to-electrical conversion in frequency channel switching, the AFP looks to offer valuable potential in silicon photonic network design.

description: The Los Humeros Volcanic Complex (LHVC) is a large silicic caldera complex in the Trans-Mexican Volcanic Belt (TMVB), hosting a geothermal field currently in exploitation by the Comision Federal de Electricidad (CFE) of Mexico, with an installed capacity of ca. 95 MW of electric power. Understanding the structural architecture of LHVC is important to get insights into the interplay between the volcano-tectonic setting and the characteristics of the geothermal resources in the area. The analysis of volcanotectonic interplay in LHVC benefits from the availability of subsurface data obtained during the exploration of the geothermal reservoir that allows the achievement of a 3D structural view of the volcano system. The LHVC thus represents an important natural laboratory for the development of general models of volcano-tectonic interaction in calderas.

description: Charge lifetime of strained superlattice GaAs photocathodes in DC guns is limited by ion back bombardment. It needs to be improved at least an order of magnitude to meet the requirements for future colliders such as Electron-Ion Collider (EIC). In this work, we propose and present simulation results for an offset anode scheme to increase charge lifetime in DC guns. This scheme eliminates the bombardment of high energy ions on the cathode and enables maximum usage of the available cathode area. Depending on the size of the available cathode area, this method can increase the charge lifetime by an order of magnitude compared to the current best alternative method. An anode assembly capable of in-vacuum movement is required for this method, which has been designed and fabricated at Brookhaven National Laboratory.

Machinal as a reflection of the hierarchy of privilege
Creators: name: Di Cicco, Laura
Publisher: name: University of British Columbia
Year: 2023

description: This thesis examines the play, Machinal that I directed as part of UBC’s 2021/2022 season through a feminist and hierarchical lens. Through expressionistic stylization, it parallels issues of gender and race from the time-period of the late 1920s to that of the 21st century. I examine the issues the protagonist faces and outline questions of change from one age to the next and I raise the question of privilege in society. The goal in this production was to compare and contrast practically, events from a previous period to that of today. My directorial process included research, analysis, journaling, and cultural consultations regarding language and racial issues addressed in this play. Finally, I reflect on the outcome that culminated over the months and its effect on audiences.

description: Interacting systems consisting of two rotators and a pendulum are considered, in a case in which the uncoupled systems have three very different characteristic time scales. The abundance of unstable quasi periodic motions in phase space is studied via Lindstedt series. The result is a strong improvement, compared to our previous results, on the domain of validity of bounds that imply existence of invariant tori, large homoclinic angles, long heteroclinic chains and drift--diffusion in phase space.

description: An eclipsing binary with an orbital period of 62 days has been discovered in HD 328058 and studied by UBVIcHalpha photometry. Combining the results of light curve modelling with existing stellar models and known B3-shell spectral type of the primary star then allowed a reliable estimation of the mass, radius and effective temperature of both components: about 6.9 Msun, 5.2 Rsun and 17600 K for the primary star, and about 0.78 Msun, 1.20 Rsun and 56000 K for the hot subdwarf companion of type sdO. Obviously, this binary has been created by mass transfer of the envelope of the sdO progenitor to our primary star, now being a rapidly rotating shell star. Its spheroidal distortion and its decretion disk can be studied here unusually well.

The Science of Antislavery: Scientists, Abolitionism, and the Myth of Slavery's Backwardness
Creators: Herschthal, Eric
Publisher: name: Columbia University
Year: 2017
Subjects: History

Slavery
Antislavery movements

description: "The Science of Antislavery" explores the critical though rarely studied role scientists played in the early antislavery movement. It argues that scientists not only helped legitimize abolitionism but also helped create the myth that slavery was a backward institution. During the Age of Revolution (1770-1830), when antislavery societies first took root, abolitionism attracted many scientific supporters. Though their refutations of scientific racism are perhaps better known, they also made many arguments that went beyond race. Chemists argued that new chemical techniques would fertilize the soil more effectively, which would in turn reduce the need for slave labor. Botanists touted the natural environments of new British colonies in Africa and Southeast Asia, contending that they would make ideal free labor alternatives to Caribbean plantations. Geologists argued that the western American frontier, with its unique mineral deposits, was best suited to free white agricultural settlements rather than slavery’s expansion. Even by the 1830s, when the movement was taken over by a more radical, less elite multiracial coalition, scientific arguments continued to influence antislavery arguments. From the 1830s until the Civil War, antislavery supporters on both sides of the Atlantic argued that slaveholders’ alleged refusal to adopt new machinery was evidence of their backwardness. Today, as a new generation of historians demonstrate how modern slavery in fact was, The Science of Antislavery shows how the idea that it was somehow never modern came into being.

description: In this work we show that the Universe evolving in a spacetime with torsion (originated from a second rank antisymmetric Kalb-Ramond field) and dilaton is free from any big bang singularity and can have acceleration during the evolution. Both the matter and radiation dominated era have been considered and the role of the dilaton to explain the decelerating phase in the earlier epoch has also been discussed.
