Islamic Political Thought: Reviving a Rationalist Tradition

This work develops the foundations of an Islamic argument for secular, liberal democracy from within the Islamic discursive tradition. First, it challenges the presentation of contemporary Islamic political thought as a unified, continuous development of the classical canon by showing the influence of the now marginalized medieval rationalists in the development of Islamic political thought. The classical rationalist concern with divine justice forced the founders of Sunni orthodoxy to state their epistemologies and their positions on ethical ontology. The orthodox positions, and their related methods of legal-juristic reasoning, are shown to be incapable of accommodating the modern Islamic positions on political representation, slavery, and just war. This leads to the second argument of the work, that the modern Islamic discourse is better understood as a reflection of the central concern with justice and its rationalist epistemology and ethical ontology we find in the writings of classical rationalists. This argument is made by examining the works of three classical rationalists, a theologian, a philosopher, and a historian. Their political positions, shaped by their rationalism and concern with justice, challenged their orthodox contemporaries, and provide substantive critiques of the classical political accommodations, methods of politico-legal reasoning, and hence, of modern Islamist political projects. The final chapter reveals how far the mainstream of Islamic political thought has deviated from the classical discourses, since the 19th century, by adopting the language and ideals of the European Enlightenment. This shift is presented as a triumph of classical rationalism over literalism, whose epistemological foundations and ontological implications have yet to be acknowledged and appreciated.

Representational Subversions and the Limits of Postcoloniality: Shahzia Sikander's Strategic Contemporaneity

Transnational artist Shahzia Sikander challenges the limitations of Edward Said's postcolonial emphasis on secular humanism by deploying the heterogeneous traditions of South Asian miniature painting while strategically drawing on tradition to critique contemporaneity. Through a palimpsest process of composition, Sikander reincorporates the unknown and silenced histories implicit in the tradition of miniature painting to create social imaginaries with motifs that draw on the diverse traditions of South Asian religions and aesthetics to create a subversive politics of remembering wherein alternative images of cosmopolitanism emerge. Through a sustained analysis, this dissertation demonstrates how these alternative traditions interrogate and critique the limitations of postcolonial theory. Particularly important to this critique are some recent approaches of Third World feminists that highlight the limitations of secular humanism implicit in much of postcolonial critique. Sikander's compositions mirror these approaches as her motifs of the feminine become an intervention into the spiritual emptiness and ethical confusions of contemporaneity. In effect, Sikander's work is an intervention, a warning, and a plea for the re-invention of positive alternatives as her images embody and facilitate a critical and daring consciousness that is necessary to both our social and spiritual well-being.

CANDELS: The progenitors of compact quiescent galaxies at z ~ 2

We combine high-resolution Hubble Space Telescope/WFC3 images with multi-wavelength photometry to track the evolution of structure and activity of massive (M_*> 10^10 M_☉) galaxies at redshifts z = 1.4-3 in two fields of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. We detect compact, star-forming galaxies (cSFGs) whose number densities, masses, sizes, and star formation rates (SFRs) qualify them as likely progenitors of compact, quiescent, massive galaxies (cQGs) at z = 1.5-3. At z≲2, cSFGs present SFR = 100-200 M_☉ yr^–1, yet their specific star formation rates (sSFR ~ 10^–9 yr^–1) are typically half that of other massive SFGs at the same epoch, and host X-ray luminous active galactic nuclei (AGNs) 30 times (~30%) more frequently. These properties suggest that cSFGs are formed by gas-rich processes (mergers or disk-instabilities) that induce a compact starburst and feed an AGN, which, in turn, quench the star formation on dynamical timescales (few 10^8 yr). The cSFGs are continuously being formed at z = 2-3 and fade to cQGs down to z ~ 1.5. After this epoch, cSFGs are rare, thereby truncating the formation of new cQGs. Meanwhile, down to z = 1, existing cQGs continue to enlarge to match local QGs in size, while less-gas-rich mergers and other secular mechanisms shepherd (larger) SFGs as later arrivals to the red sequence. In summary, we propose two evolutionary tracks of QG formation: an early (z≲2), formation path of rapidly quenched cSFGs fading into cQGs that later enlarge within the quiescent phase, and a late-arrival (z≳2) path in which larger SFGs form extended QGs without passing through a compact state.

Everyday Indivisibility: How Exclusive Religious Practices Explain Variation in Subnational Violence Outcomes

This project explores the puzzle of religious violence variation. Religious actors initiate conflict at a higher rate than their secular counterparts, last longer, are more deadly, and are less prone to negotiated termination. Yet the legacy of religious peacemakers on the reduction of violence is undeniable. Under what conditions does religion contribute to escalated violence and under what conditions does it contribute to peace? I argue that more intense everyday practices of group members, or high levels of orthopraxy, create dispositional indivisibilities that make violence a natural alternative to bargaining. Subnational armed groups with members whose practices are exclusive and isolating bind together through ritual practice, limit the acceptable decisions of leaders, and have prolonged timeframes, all of which result in higher levels of intensity, intransigence and resolve during violent conflict. The theory challenges both instrumentalist and constructivist understandings of social identity and violence. To support this argument, I construct an original cross-national data-set that employs ethnographic data on micro-level religious practices for 724 subnational armed groups in both civil wars and terror campaigns. Using this data, I build an explanatory “religious practice index” for each observation and examine its relationship with conflict outcomes. Findings suggest that exclusive practice groups fight significantly longer with more intensity and negotiate less. I also apply the practice model to qualitative cases. Fieldwork in the West Bank and Sierra Leone reveals that groups with more exclusive religious practicing membership are principle contributors to violence, whereas those with inclusive practices can contribute to peace. The project concludes with a discussion about several avenues for future research and identifies the practical policy applications to better identify and combat religious extremism.

Tracing an American Yoga: Identity and Cross-Cultural Transaction

This dissertation looks at the creative identity of an American yoga, both rooted in its Indic origins and radically transformed in its U.S. manifestations. It traces the broad historical transactions of yoga in terms of East and West, Secular and Religious, authenticity and idealized conception, as well as provides a critical historical genealogy of Anusara and Sridaiva yoga. Furthermore, the project relates yoga to the identity, power, and knowledge dynamics of pre-modern, modern, and postmodern histories and interpretations of yoga and Tantra, multiple theoretical discourses, and the embodied practices of individuals within Indian and American contexts. I argue that there is a unique and polysemous yogic identity in America, and that this identity has developed from a messy process of transaction between Indian and Western modes of being and knowing. Furthermore, the current Americanized culture of yoga brings along with it narratives of specific value. American yoga displays a particularly consumptive quality of yogic lifestyle that reflects a cultural atmosphere of reinvention and a merging of profit and personal purpose. American yoga’s identity today is entrepreneurial, branded, business oriented, and marketed for consumption. This dissertation shows how the American yogic identity is in flux, continuously fracturing and multiplying into various and novel understandings that relate to yoga’s past and to the market value for today’s American consumer. It examines the moving nature of yoga in the American landscape as what Jared Farmer calls a “center of creativity” and as a display of excess and choice. The discussion of yoga is further located in John Friend’s styles of yoga and/or lifestyle practices, Anusara and Sridaiva, as they both redefine and further remove yoga from established Indian markers of identity. My locations as American yogi, as comparativist, as ethnographer, and as a Bachelor of Science in Advertising and Marketing also situate this analysis.

Cover to be unveiled : how meaning is revealed with sheer veils in paintings by Lucas Cranach The Elder

While scholars have questioned the meaning of Lucas Cranach the Elder’s sheer veils when associated with sensual nude figures, research about sheer veils adorning women in a religious context in his paintings has not yet been developed. Through a primarily iconographical approach, I explore who dons each type of veil, and when, to better understand why the same sheer veil is worn differently by various individuals and what that could mean relative to Cranach’s body of work. These veils exhibit artistic prowess, but analysis of their placement on individual figures also reveals how Cranach’s repeated use of sheer veils in his paintings trains the eye on underlying messages, unlocking meanings of these works for Cranach and his patrons and broader themes present in sixteenth century visual culture. My paper initiates this important discussion about how sheer veils – often overlooked in Cranach’s works – are used in both religious and secular contexts.

The Role of Education and Government in Shaping Muslim Women's Rights: Three Contemporary Case Studies

The rise in Muslim terrorist activities has encouraged the West to reevaluate its understanding of Islam, prompting concern for Muslim women's rights. In search of education-based solutions, this project explores three case studies of Muslims living under different government types: a secular state with a primarily Muslim population (Turkey); a secular state with a significant Muslim minority population (France); and a Muslim state with a powerful religious influence (Afghanistan). The type of government plays a significant role in Muslim women's rights, and solutions must be based on individual aspects of each unique place where Muslims live today. The results show that education is a universal solution when accepted at all levels: governmental, communal, and the individual.

A new algorithm to accelerate harmonic analysis of time series

The Lomb periodogram has been traditionally a tool that allows us to elucidate if a frequency turns out to be important for explaining the behaviour of a given time series. Many linear and nonlinear reiterative harmonic processes that are used for studying the spectral content of a time series take into account this periodogram in order to avoid including spurious frequencies in their models due to the leakage problem of energy from one frequency to others. However, the estimation of the periodogram requires long computation time that makes the harmonic analysis slower when we deal with certain time series. Here we propose an algorithm that accelerates the extraction of the most remarkable frequencies from the periodogram, avoiding its whole estimation of the harmonic process at each iteration. This algorithm allows the user to perform a specific analysis of a given scalar time series. As a result, we obtain a functional model made of (1) a trend component, (2) a linear combination of Fourier terms, and (3) the so-called mixed secular terms by reducing the computation time of the estimation of the periodogram.

The outburst decay of the low magnetic field magnetar SGR 0418+5729

We report on the long-term X-ray monitoring of the outburst decay of the low magnetic field magnetar SGR 0418+5729 using all the available X-ray data obtained with RXTE, Swift, Chandra, and XMM-Newton observations from the discovery of the source in 2009 June up to 2012 August. The timing analysis allowed us to obtain the first measurement of the period derivative of SGR 0418+5729: ˙ P = 4(1) × 10−15 s s−1, significant at a ∼3.5σ confidence level. This leads to a surface dipolar magnetic field of Bdip 6 × 1012 G. This measurement confirms SGR 0418+5729 as the lowest magnetic field magnetar. Following the flux and spectral evolution from the beginning of the outburst up to ∼1200 days, we observe a gradual cooling of the tiny hot spot responsible for the X-ray emission, from a temperature of ∼0.9 to 0.3 keV. Simultaneously, the X-ray flux decreased by about three orders of magnitude: from about 1.4 × 10−11 to 1.2 × 10−14 erg s−1 cm−2. Deep radio, millimeter, optical, and gamma-ray observations did not detect the source counterpart, implying stringent limits on its multi-band emission, as well as constraints on the presence of a fossil disk. By modeling the magneto-thermal secular evolution of SGR 0418+5729, we infer a realistic age of ∼550 kyr, and a dipolar magnetic field at birth of ∼1014 G. The outburst characteristics suggest the presence of a thin twisted bundle with a small heated spot at its base. The bundle untwisted in the first few months following the outburst, while the hot spot decreases in temperature and size. We estimate the outburst rate of low magnetic field magnetars to be about one per year per galaxy, and we briefly discuss the consequences of such a result in several other astrophysical contexts.

A new low magnetic field magnetar: the 2011 outburst of Swift J1822.3–1606

We report on the long-term X-ray monitoring with Swift, RXTE, Suzaku, Chandra, and XMM-Newton of the outburst of the newly discovered magnetar Swift J1822.3–1606 (SGR 1822–1606), from the first observations soon after the detection of the short X-ray bursts which led to its discovery, through the first stages of its outburst decay (covering the time span from 2011 July until the end of 2012 April). We also report on archival ROSAT observations which detected the source during its likely quiescent state, and on upper limits on Swift J1822.3–1606's radio-pulsed and optical emission during outburst, with the Green Bank Telescope and the Gran Telescopio Canarias, respectively. Our X-ray timing analysis finds the source rotating with a period of P = 8.43772016(2) s and a period derivative P = 8.3(2)×10−14 s s−1, which implies an inferred dipolar surface magnetic field of B sime 2.7 × 1013 G at the equator. This measurement makes Swift J1822.3–1606 the second lowest magnetic field magnetar (after SGR 0418+5729). Following the flux and spectral evolution from the beginning of the outburst, we find that the flux decreased by about an order of magnitude, with a subtle softening of the spectrum, both typical of the outburst decay of magnetars. By modeling the secular thermal evolution of Swift J1822.3–1606, we find that the observed timing properties of the source, as well as its quiescent X-ray luminosity, can be reproduced if it was born with a poloidal and crustal toroidal fields of Bp ~ 1.5 × 1014 G and B tor ~ 7 × 1014 G, respectively, and if its current age is ~550 kyr.

Quiescent state and outburst evolution of SGR 0501+4516

We report on the quiescent state of the soft gamma repeater SGR 0501+4516 observed by XMM–Newton on 2009 August 30. The source exhibits an absorbed flux ∼75 times lower than that measured at the peak of the 2008 outburst, and a rather soft spectrum, with the same value of the blackbody temperature observed with ROSAT back in 1992. This new observation is put into the context of all existing X-ray data since its discovery in 2008 August, allowing us to complete the study of the timing and spectral evolution of the source from outburst until its quiescent state. The set of deep XMM–Newton observations performed during the few years time-scale of its outburst allows us to monitor the spectral characteristics of this magnetar as a function of its rotational period, and their evolution along these years. After the first ∼10 d, the initially hot and bright surface spot progressively cooled down during the decay. We discuss the behaviour of this magnetar in the context of its simulated secular evolution, inferring a plausible dipolar field at birth of 3 × 1014 G, and a current (magnetothermal) age of ∼10 kyr.

Manchester, Chetham's Library MS 8009 (Mun. A.6.31): A Codicological Description

This article presents a complete codicological description of Manchester, Chetham's Library, MS 8009 (Mun.A.6.31), a late fifteenth-century production that contains a combination of secular and religious texts. The manuscript's significance for both the literary and textual scholar was recognized by Derek Pearsall when he suggested its suitability for a facsimile edition. The restrictions imposed by the Governors of the Library for reproduction under the present conditions, however, suggest that Pearsall's recommendation may have to wait for some time. The purpose of this paper is to fill that void by correcting some inaccuracies in previous descriptions and completing them with supporting visual evidence.

El relato por otros medios: ¿un giro transmediático?

La reflexión en torno a las narraciones transmediáticas ha sido muy intensa en los últimos diez años. En este artículo intentamos desbrozar el concepto, dar cuenta de su especificidad y mostrar algunos ejemplos clásicos y otros más recientes. También apuntaremos algunas dificultades y retos que plantea a los estudios no sólo narratológicos, sino también en los márgenes entre estos y otros dominios tanto semióticos como de los Media Studies: las dimensiones y los límites de una “historia” de la narración transmedia, las explicaciones económicas de su pujanza actual, el afán de construcción de universos narrativos complejos y la inmersión en ellos de los fans, el papel crucial de la serialidad, la dimensión promocional y más en general paratextual de las narraciones trasmediáticas y finalmente la extensión del fenómeno más allá del dominio de la ficción. El “giro narrativo” descrito en las ciencias sociales y en muchos discursos públicos hace ya unas décadas debería complementarse ahora con un “giro transmediático”, funcional al primero y a la manera de su brazo secular (tecnológico y económico).

El papel del clero en la expulsión de los jesuitas decretada por Carlos III en 1767

El presente trabajo trata sobre la reacción del clero secular y regular ante la expulsión de los jesuitas de la monarquía hispánica en 1767. Veremos las opiniones de algunos de los obispos favorables a la política regalista de Carlos III, y cómo actuaron antes la operación mejor diseñada y más eficaz contra la Compañía de Jesús en los amplios territorios del monarca Borbón. Al mismo tiempo, analizaremos los comentarios de los propios expulsos sobre el clero español y las consecuencias que tuvieron ambas reacciones.

Religiosas y laicas en el franquismo: entre la dictadura y la oposición

En este trabajo se ofrece un estado de la cuestión sobre la evolución de las religiosas y las seglares, de clase media y obreras, de Acción Católica en el franquismo, una dictadura que encontró en la Iglesia a uno de sus principales apoyos. En los años cuarenta y cincuenta participan del control político y moral de las españolas y su presencia pública es destacada. En las décadas siguientes experimentan un profundo cambio hacia un mayor compromiso, todo lo cual conduce a un escenario de tensiones con la dictadura y la jerarquía eclesiástica, y a una crisis que da lugar a la secularización de muchas religiosas y al abandono de Acción Católica de numerosas militantes; en esta etapa de mayor testimonio sin embargo su reconocimiento disminuye.
