description: Pulsars are known for their superb timing precision, although glitches can interrupt the regular timing behavior when the stars are young. These glitches are thought to be caused by interactions between normal and superfluid matter in the crust of the star. However, glitching pulsars such as Vela have been shown to require a superfluid reservoir that greatly exceeds that available in the crust. We examine a model in which glitches tap the superfluid in the core. We test a variety of theoretical superfluid models against the most recent glitch data and find that only one model can successfully explain up to 45 years of observational data. We develop a new technique for combining radio and X-ray data to measure pulsar masses, thereby demonstrating how current and future telescopes can probe fundamental physics such as superfluidity near nuclear saturation.

Towards a sustainable plan for new tube houses in Vietnam
Creators: name: Nguyen, Phan Anh
Publisher: name: International Planning History Society Proceedings
Year: 2016

description: In Vietnam, the history of cities can easily be seen through their urban patterns, landscapes and housing typologies. Most recently, the economic reform in 1986 has resulted in huge impact on the Vietnamese society. The rapid economic growth and privatisation of the market has resulted in the appearance and significant development of the “new tube house” which soon became the most dominant housing type in Vietnam. Hanoi, the capital city of Vietnam, has a long history and also is very rich in architectural styles and typologies which are reflected in its urban pattern. However, there is no actual clear boundary in urban scale as the new tube houses are scattered all over the city and they are adapted differently to the contexts. This paper aims to investigate how the traditional urban tube houses in Hanoi transformed into the new tube house and, on the other hand, present the results of a survey conducted in Vietnam on how these houses respond to the Vietnam local climate and perform in terms of energy consumption.

description: We study a singlet-triplet Josephson junction between a conventional s-wave superconductor and an unconventional p$_{\rm x}$-wave superconductor. The Andreev spectrum of the junction yields a spontaneous magnetization in equilibrium. This allows manipulating the occupation of the Andreev levels using an ac Zeeman field. The induced Rabi oscillations manifest themselves as a resonance in the current-phase relation. For a circularly polarized magnetic field, we find a spin selection rule, yielding Rabi oscillations only in a certain interval of the superconducting phase difference.

The Neoliberal Urbanization in São Paulo, Brazil: the case of Agusta Park
Creators: name: Levy, Dan

Publisher: name: International Planning History Society Proceedings
Year: 2016

description: The purpose of this article is to understand the consequences of accelerated neoliberal urbanization in the city of São Paulo by analyzing the Augusta Park and it’s environs. The study is justified because this city has been pursuing neoliberal practices that generate social and urban fragmentation. The current neoliberal scenario transforms the urban space and restructures the city, it creates marginalized and segregated urban environments, and replaces public spaces with private amenities. The research question is the following: Does Augusta Park represent a kind of resistance to accelerated neoliberal urbanization in São Paulo? To support this research, we use a qualitative methodology in order to demonstrate the urban destruction that threatens this area, the object of this study. First, we contextualize the Augusta Park as a public space with twenty four thousand square metres, located on Augusta Street, in the downtown area of São Paulo, representing a significant green area, a scarce amenity in this region. Then we demonstrate that in recent years, due to the increasing valuation of real estate in the downtown area, the region has become a strong target for the property market who intend to suppress the Park to make way for modern and luxurious housing. This fact has generated a large mobilization of the park’s users, locals and others, who demand that this area be preserved and handed over to the population in the form of a public space in all of its integrity. The case remains a legal process in the courts due to the influence of real estate capital on the Government. The research aims to reveal the historical and urban importance of the Park for the region and the impact of the developers activities in the urban environment. Historically the above issues have been justified by man’s domination of his environment. So, it is inevitable to analyse the instruments for environmental protection, especially National Urban Development Policy in Brazil. In conclusion we believe that the urban landscape of the city of São Paulo is changing quickly and intensely, causing profound changes to the city’s structure. The accelerated neoliberal urbanization process contributes significantly to this scenario with the main actors being the property and financial markets. Despite neoliberal practices producing devastating effects on the local way of life, promoting the disintegration of history as well as the memory of the city and decaying urban spaces definitively, Augusta Park reveals itself as a potential resistance to this neoliberal influence.

description: Combining 3D smoothed-particle hydrodynamics and Monte Carlo radiative transfer calculations, we examine the morphology of spiral density waves induced by gravitational instability (GI) in protoplanetary disks, as they would appear in direct images at near-infrared (NIR) wavelengths. We find that systems with disk-to-star-mass ratios q=M_disk/M_star that are ~0.25 or more may produce prominent spiral arms in NIR imaging, remarkably resembling features observed in the MWC 758 and SAO 206462 systems. The contrast of GI-induced arms at NIR wavelengths can reach a factor of ~3, and their pitch angles are about 10-15 degree. The dominant azimuthal wavenumber of GI-induced spiral arms roughly obeys m~1/q in the range 2~0.25; and that the accretion rate Mdot be high, on the order of 1e-6 solar mass per year.

Tram-cars, tents, igloos and garages: An institutional-theoretical lens on temporary dwellings in Australia
Creators: name: Pullan, Nicola
Publisher: name: International Planning History Society Proceedings
Year: 2016

description: Following World War II, Australia was confronted by a severe shortage of dwellings. One relief valve for some cities was a stock of un-serviced building lots situated on the suburban fringe. In Sydney, Australia’s largest city, thousands of aspiring home-owners purchased such land but, affected by shortages of money and materials, were only able to construct a temporary dwelling. These homes ranged from shacks and garages to tram-cars, Nissen-huts and tents. The post-war phenomenon of such housing in Australia has been neglected both empirically and theoretically. This paper draws upon Sorensen’s suggestion of Historical Institutionalism in an attempt to pursue the theoretical challenge. The proposition explored is that the existence of temporary dwellings in Sydney was evidence of a critical juncture in the institutionalised regulation of housing, creating opportunities for policy change. Firstly, local authorities were forced to permit the occupation of dwellings which did not comply with existing ordinances, and secondly, they adapted their regulations to give permanent approval to sub-standard accommodation. The paper concludes by suggesting that policy changes reverted to the institutionalised model for two reasons: path dependency and positive feedback mechanisms privileged those committed to an unchanged institution, while the permanent housing converged with adapted regulations.

Unique Case of Squatter Prevention Projects in Turkey: the Tozkoparan Neighbourhood, Istanbul

Publisher: name: International Planning History Society Proceedings
Year: 2016

description: Istanbul is a metropolitan city, owing the foundations of its physical form to many harsh urban decisions made through the 1950's. Rapid urbanization and internal immigrations, caused an urgent need of housing resulted in an uncontrolled, unplanned growth of the city. The public authorities, constrained by an inertia, offered only limited solutions to shelter the urban poor. Instead, the public investments were assigned to the construction of new highways and housing for middle to upper middle class. Old neighbourhoods in the historic center of the city were torn apart in order to accommodate a new, automobile-based life style and many former residents of the city had to be evicted and relocated. Tozkoparan neighbourhood, the case study investigated in this paper, is the first example of “Squatter Prevention Projects”, an exception to the urban conditions, as it is a public housing project intended to shelter those evicted from their houses or incapable to dwell in formal houses. Among a limited number of projects countrywide, Squatter Prevention Projects were made possible with the Squatter Act of 1966. Yet with the shifting urban politics after 1980's, these projects become the target of a new, urban renewal discourse, which would result in a radical transformation of the neighbourhoods. An investigation across changing housing politics in Turkey shows firstly the state organizations' late attempt to deal with the internal immigration and an unplanned expansion of illegal neighbourhoods. The immigration provided the required labour power for the growing city, yet the housing policies could not manage the increase of urban population. A big part of the new inhabitants had to find their own solution. Finally the social state was able to provide the necessary investment into social housing. The case study also reveals that it has been a critical point in the urban planning history of Turkey, the attempt of becoming a social state was interrupted by military coups and newly introduced neoliberal politics. Our paper, at first, briefly depicts the Act of 1966 and the Tozkoparan Project. Secondly, offering a short overview of the last 40 years of the neighbourhood, deals with the emerging issue of the so-called liberal policies against the urban poor. The spatial interventions done by the inhabitants through this period are also considered as an important aspect of this overview. Respectively many of the appropriations show the lack of certain qualities in the planning of the project.

description: This paper presents the development of a ver- satile and modular real-time audio effect unit called the Daisy Dub for music producers, performers and DJs. The device utilises the state of the art Daisy Seed development board by Electrosmith and comes with a custom made PCB and hardware case. It features a range of real-time audio effects, with an emphasis on creative delays and includes a range of modulation effects and filters in its feedback path. In addition, the unit is compact and portable, with an interactive graphical interface, four knobs and two arcade buttons for performance control, an encoder for menu diving, and an OLED screen for spectrum analysis. It features quadrophonic audio processing in real-time and is portable and powered by USB Type-C. DSP is developed with Gen by Cycling ’74 and took inspiration from state of the art hardware audio delay units and modular real-time audio effect processors. A series of DSP and hardware evaluation tests were performed along with two usability tests, from the early cardboard prototype to the final manufactured device to evaluate the effectiveness and usability. Our research demonstrates the feasibility and potential of creating a versatile and modular real-time audio effect for music production and live performance. The Daisy Dub offers a modern take on contemporary real-time audio effects, emphasising a delay effect, and we believe it contributes to the field of audio effects and the music making industry in general.
CIAM 8. The Heart of the City as the symbolical resilience of the city
Creators: name: Zuccaro Marchi, Leonardo
Publisher: name: International Planning History Society Proceedings
Year: 2016

description: The “Heart of the City”, title of the 8th CIAM (Congrès Internationaux d'Architecture Moderne), held in 1951, is a contradictory and pervasive figure of speech which has marked a thinking and urban transition after the 2nd World War and still affects our contemporary urban and social condition. In 1951, two opposite urban conditions are considered by Sert, President of CIAM, as main issues which the Heart discourse should face: from the disappearance of city centres because of the destruction of the War to the negation of the urban centrality because of urban sprawl and the infinite constant enlargement of city boundaries. But the Heart itself also represents two different figures of speeches, the symbol and the metaphor: from one side it becomes a humanist symbol “which springs directly to the senses without explanation”, in opposition to the “mechanized killing”, to the “tyranny of mechanical tools” as stressed by Giedion during CIAM 8; from the other side the Heart still keeps its anatomical metaphorical organic meaning translated into a presumed right physical form and dimension of the city. These oppositions - from annulled bombed centers to infinite urban structures, from metaphor to symbol, from pro-urban to proto-urban Idea are the main causes of the complexity and of the stratification of several different layers of significances of the Heart of the City, since CIAM 8 until the present. Starting from CIAM 8, the paper investigates this Post-war urban tension, which lies at the crossroads of intellectual-theoretical and architectural-design worlds. On the one hand, there is the resilience of the decontextualized social-spatial tabula rasa created by the dangerous mechanical progress which led to the blood and horror of the War. While on the other, the resilience of embracing, stemming, and compressing the Galileo scandal, “the constitution of an infinite, and infinitely open space” (Foucault, 1967) which was, for the first time, mirrored in the urban sprawl. The aim of this paper is to focus on the complexity and the difficulty of interpreting the Heart of the City, from the tangible Janus-faced binomial reconstruction-recentralization of the urban Core, to the symbolical abstract resilience of the Heart as a constituent element at the foundation of the urban structure and anticipator of an anthropological idea of Habitat as an integrating part of the human settlement. From this analysis, the paper states that the Heart does not only concern the Post War reconstruction of the cities as has been generally thought. On the contrary, the Heart of the City is still a valid issue in our contemporary urban condition and it deals with the progressive, contemporary topic of a correct synergy between social and physical space, between the private and public sphere.

The Klein-Gordon-Fock equation in the curved spacetime of the Kerr-Newman (anti) de Sitter black hole

description: Exact solutions of the Klein-Gordon-Fock (KGF) general relativistic equation that describe the dynamics of a massive, electrically charged scalar particle in the curved spacetime geometry of a charged, rotating Kerr-Newman-(anti) de Sitter black hole are investigated. In the general case of a rotating, charged, cosmological black hole the solution of the KGF equation with the method of separation of variables results in Fuchsian differential equations for the radial and angular parts which contain more than three finite singularities and thereby generalise the Heun differential equations (HE). For particular values of the physical parameters (i.e mass of the scalar particle) these Fuchsian equations reduce to Heun equations and the solutions are expressed in terms of Heun functions. For other values of the parameters some of the extra singular points are false singular points. We derive the conditions on the coefficients of the generalised Fuchsian equation such that a singular point is a false point. In such a case the exact solution of the Fuchsian equation can in principle be simplified and expressed in terms of Heun functions. We also derive the exact solutions of the radial and angular equations for a massive scalar (charged) particle in the Kerr-Newman spacetime. The analytic solutions are expressed in terms of confluent Heun functions. Moreover, we derived the constraints on the parameters of the theory such that the solution simplifies and expressed in terms of confluent Kummer hypergeometric functions. We also investigate the radial solutions in the KN case in the regions near the event horizon and far from the black hole. Finally, we construct several expansions of the solutions of the HE in terms of generalised hypergeometric functions of Lauricella-Appell.

The [CII] Deficit in LIRGs and ULIRGs is Due to High-Temperature Saturation

description: Current predictions for the line ratios from photo-dissociative regions (PDRs) in galaxies adopt theoretical models that consider only individual parcels of PDR gas each characterized by the local density and far-UV radiation field. However, these quantities are not measured directly from unresolved galaxies, making the connection between theory and observation ambiguous. We develop a model that uses galaxy-averaged, observable inputs to explain and predict measurements of the [CII] fine structure line in luminous and ultra-luminous infrared galaxies. We find that the [CII] deficit observed in the highest IR surface-brightness systems is a natural consequence of saturating the upper fine-structure transition state at gas temperatures above 91 K. To reproduce the measured amplitude of the [CII]/FIR ratio in deficit galaxies, we require that [CII] trace approximately 10-17% of all gas in these systems, roughly independent of IR surface brightness and consistent with observed [CII] to CO(1--0) line ratios. Calculating the value of this fraction is a challenge for theoretical models. The difficulty may reside in properly treating the topology of molecular and dissociated gas, different descriptions for which may be observationally distinguished by the [OI]63 micron line in yet-to-be-probed regions of parameter space, allowing PDR emission lines from to probe not only the effects of star formation but also the state and configuration of interstellar gas.

Mapping the Middle East: From Bonaparte's Egypt to Chateaubriand's Palestine
Creators: name: Sawafta, Suja Reyad
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This project focuses on the impact that Napoleon Bonaparte's invasion of Egypt had on François-Réné de Chateaubriand's Itinéraire de Paris à Jérusalem. Napoleon's campaign in Egypt set forth an unprecedented imperial ideology that sought to know and thus conquer the Middle East in every facet. The scientific findings of the campaign were immortalized in a twenty-three-volume work known as La Description de l'Égypte, which recounted a narrative of French imperial domination and cultural superiority. In this project, I draw a link between the process of mapping and representations found in the Description and Chateaubriand's continuation of both the imperial narrative and the erasure of the `Other' in his Itinéraire.

description: Quantum repeater holds the promise for scalable long-distance quantum communication. Towards a first quantum repeater based on memory-photon entanglement, significant progresses have made in improving performances of the building blocks. Further development is hindered by the difficulty of integrating key capabilities such as long storage time and high memory efficiency into a single system. Here we report an efficient light-matter interface with sub-second lifetime by confining laser-cooled atoms with 3D optical lattice and enhancing the atom-photon coupling with a ring cavity. An initial retrieval efficiency of 76(5)% together with an 1/e lifetime of 0.22(1) s have been achieved simultaneously, which already support sub-Hz entanglement distribution up to 1000 km through quantum repeater. Together with an efficient telecom interface and moderate multiplexing, our result may enable a first quantum repeater system that beats direct transmission in the near future.

Year: 2009

description: The purpose of this study was to examine the motivating factors that contributed to annual contributions at three different NCAA institutions. Annual Fund donors at each participating school were contacted via e-mail and asked to take part in an online survey. Data was obtained from over 5,000 donors, including general demographic information as well as motivating factors that led to their annual contribution. Using a Principle Component Analysis (PCA) motivating factors were grouped together and further analyzed to explore significant differences between the three institutions. Significant differences existed between all schools or two of the three schools when measured with each component. Motives deemed to be reciprocal were one of the components significantly different. The motives for giving were also measured between Alumni and Non-Alumni at each institution, with similar results.

description: One of the principal difficulties in stochastic homogenization is transferring quantitative ergodic information from the coefficients to the solutions, since the latter are nonlocal functions of the former. In this paper, we address this problem in a new way, in the context of linear elliptic equations in divergence form, by showing that certain quantities associated to the energy density of solutions are essentially additive. As a result, we are able to prove quantitative estimates on the weak convergence of the gradients, fluxes and energy densities of the first-order correctors (under blow-down) which are optimal in both scaling and stochastic integrability. The proof of the additivity is a bootstrap argument, completing the program initiated in \cite{AKM}: using the regularity theory recently developed for stochastic homogenization, we reduce the error in additivity as we pass to larger and larger length scales. In the second part of the paper, we use the additivity to derive central limit theorems for these quantities by a reduction to sums of independent random variables. In particular, we prove that the first-order correctors converge, in the large-scale limit, to a variant of the Gaussian free field.

description: The paper reports results of a survey among active forecasters of the German business cycle. Relying on 82 respondents from 37 different institutions, we investigate what models and theories forecasters subscribe to and find that they are pronounced conservative in the sense, that they overwhelmingly rely on methods and theories that have been well-established for a long time, while more recent approaches are relatively unimportant for the practice of business cycle forecasting. DSGE models are mostly used in public institutions. In line with findings in the literature there are tendencies of “leaning towards consensus” (especially for public institutions) and “sticky adjustment of forecasts” with regard to new information. We find little evidence that the behaviour of forecasters has changed fundamentally since the Great Recession but there are signs that forecast errors are evaluated more carefully. Also, a stable relationship between preferred theories and methods and forecast accuracy cannot be established. (150 words)

description: The physical nature and the correct definition of hydrogen bond (H-bond) are considered.\,\,The influence of H-bonds on the thermodynamic, kinetic, and spectroscopic properties of water is analyzed.\,\,The conventional model of H-bonds as sharply directed and saturated bridges between water molecules is incompatible with the behavior of the specific volume, evaporation heat, and self-diffusion and kinematic shear viscosity coefficients of water. On the other hand, it is shown that the variation of the dipole moment of a water molecule and the frequency shift of valence vibrations of a hydroxyl group can be totally explained in the framework of the electrostatic model of H-bond.\,\,At the same time, the temperature dependences of the heat capacity of water in the liquid and vapor states clearly testify to the existence of weak H-bonds.\,\,The analysis of a water dimer shows that the contribution of weak H-bonds to its ground state energy is approximately 4--5 times lower in comparison with the energy of electrostatic interaction between water molecules.\,\,A conclusion is made that H-bonds have the same nature in all other cases where they occur.

description: This paper examines underlying reasons behind communal violence and civil war and attempts to explain the role of political entrepreneurs in escalating communal violence to civil war. The author tests his theory against the conflict in Nagorno-Karabakh between Armenians and Azerbaijanis. The paper argues that communal violence transitions to civil war when and if political entrepreneurs are present in an environment absent of democracy. In this regard, the author elaborates on the role of these two variables: political entrepreneurs and the absence of democracy.
Floods and Extension Plans: discourse and projects in Southern Brazil
Creators: name: Miranda, Adriana
Publisher: name: International Planning History Society Proceedings
Year: 2016

description: This paper focuses on four extension projects on floodable areas in the city of Porto Alegre, in the State of Rio Grande do Sul. The city is in the Jacui River delta, which flows into the Guaiba Lake, one of the main waterways in Southern Brazil. Such urban projects – with similar goals amongst themselves, such as integrating housing and industries, for instance – were never implemented. However, as initiatives associated to state economic and strategic development plans (between 1935 and 1960), the study of such projects significantly contributes to the understanding of Porto Alegre’s metropolitan area in its trajectory of expansion. The Jacui delta and its islands limit Northern Porto Alegre. The projects were to be located on such wetlands, given their strategic site in relation to means of external connection, such as waterways, roads and railways. Because this area had always been subject to floods, a solution for overcoming such issue with infrastructure works was always present in the creation of projects for the delta. Porto Alegre, from its foundation to the first half of the 20thcentury, suffered with floods of the Guaiba Lake that caused major damages to the city. Because of that, from 1942, a dam and a wall were built; to this day, they influence the connection between city and Lake, maintaining the collective memory of past floods. Therefore, this work focuses on the different approaches and discourses of the authors of the extension projects for the flood issues, and on their intentions towards making such projects resilient to the recurring floods. While researching the plans, we have observed that the cost of construction work and of the expropriation needed for building the dam have contributed to postponing, deterring and modifying the execution of such projects. In spite of the failure on implementing the projects, their focus on the relation between the city and its surrounding waters became an important resource for the study of the city’s history, given that the wetlands are a significant part of its collective memory.

description: In a companion work (Paper I) we detected a large population of highly variable Young Stellar Objects (YSOs) in the Vista Variables in the Via Lactea (VVV) survey, typically with class I or flat spectrum spectral energy distributions and diverse light curve types. Here we present infrared spectra (0.9--2.5 $μ$m) of 37 of these variables, many of them observed in a bright state. The spectra confirm that 15/18 sources with eruptive light curves have signatures of a high accretion rate, either showing EXor-like emission features ($Δ$v=2 CO, Br$γ$) and/or FUor-like features ($Δ$v=2 CO and H$_{2}$O strongly in absorption). Similar features were seen in some long term periodic YSOs and faders but not in dippers or short-term variables. The sample includes some dusty Mira variables (typically distinguished by smooth Mira-like light curves), 2 cataclysmic variables and a carbon star. In total we have added 19 new objects to the broad class of eruptive variable YSOs with episodic accretion. Eruptive variable YSOs in our sample that were observed at bright states show higher accretion luminosities than the rest of the sample. Most of the eruptive variables differ from the established FUor and EXor subclasses, showing intermediate outburst durations and a mixture of their spectroscopic characteristics. This is in line with a small number of other recent discoveries. Since these previously atypical objects are now the majority amongst embedded members of the class, we propose a new classification for them as MNors. This term (pronounced emnor) follows V1647 Ori, the illuminating star of McNeil's Nebula.

description: Der Aufsatz analysiert die Bedeutung des regionalen Bevölkerungsanteils einer Herkunftsgruppe
für die Arbeitsmarktintegration von drei Migrantengruppen in Deutschland. Dabei
wird untersucht, ob ein einheitlicher Effekt der Gruppengröße besteht, oder ob sich die Gruppengröße für verschiedene Migrantengruppen und verschiedene Indikatoren der Arbeitsmarktintegration unterschiedlich auswirkt.
Für die Analyse werden Daten des Sozio-oekonomischen Panels (SOEP) verwendet und kreuzklassifizierte Mehrebenenmodelle geschätzt. Der verwendete Datensatz enthält 10.970 Beobachtungen von Befragten mit türkischem, griechischem oder italienischem Migrationshintergrund. Es zeigt sich grundsätzlich kein signifikanter Effekt der regionalen Gruppengröße auf das Arbeitslosigkeitsrisiko. Für den Status Erwerbstätiger findet sich ein signifikanter, nichtlinearer Effekt, der allerdings zwischen den verschiedenen Herkunftsgruppen variiert. Deutlich wird, dass Ergebnisse zum Zusammenhang zwischen regionaler Gruppengröße und der Arbeitsmarktintegration einer Herkunftsgruppe nicht auf andere Herkunftsgruppen (und
Indikatoren der Arbeitsmarktintegration) übertragen werden können.
description: The paper analyses the role of the relative regional group size for the labor market integration
of three different ethnic groups in Germany. The analysis addresses the question of whether
there is a consistent group size effect, or if group size functions differently for different immigrant groups and for different indicators of labor market integration in Germany.
Using data provided by the German Socio-Economic Panel Study (SOEP) multilevel cross-classification models are fitted. The final dataset contains 10,970 observations from Turkish,
Greek, and Italian immigrants, and their offspring. Results generally show no effect of relative
regional group size on the risk of unemployment, but a significant effect on job status. The
effect is nonlinear, and manifests differently for each ethnic group. It becomes apparent that
findings on the relationship between group size and labor market integration found for one
immigrant group cannot readily be extended to other origin groups.

Cities under Siege: Flood in 1931 and Environmental Challenges of Chinese Urban Modernization
Creators: name: Ye, Zhiguo
Publisher: name: International Planning History Society Proceedings
Year: 2016

description: The paper explores the connection between China’s urban modernization and the resulted environmental vulnerabilities revealed in the 1931 flood. The flood in 1931 is believed to be the deadliest disaster in 20th century China with one-fourth of China’s population affected. The paper challenges the conventional view that the flood was an “unavoidable” natural disaster mainly caused by bad weather conditions (namely heavy rain, a historic high water level, and low-lying ground of the Jianghan plain). The explanation does not address why key urban centers along the Yangzi appeared unusually vulnerable and suffered great loss in the flood of 1931. The paper takes the worst affected urban region in 1931—Wuchang, Hankou and Hanyang as focus of the study. Flood prevention was historically important to the three riverine cities. In traditional China the walled cities with designed hydraulic schemes often provided shelters for people from rural hinterland during the time of flooding. However the three cities were only found defenseless in 1931 after experiencing the rapid urban modernization since the late 19th century. The study specifically examines the urban reconstruction efforts made in the Qing and the Republic and their impacts on the urban flood protection prior to 1931. It explores how the shifting focus of the government from agriculture to trade prioritized urban developmental pattern incompatible with the traditional water-control design. For instance, the rapid urban sprawl since the late Qing caused the reclamation of wetlands and lakes outside city walls preserved as high-water discharge zone. The dismantling of the flood-resistant city walls, locks and moat seriously weakened the traditional urban drains system. In addition, the birth of “the developmental state” in the Republic era marked a new chapter of the Chinese centralized urban modernization with technocratic confidence and industrial ambition. After 1927 the urban social reform reflected a drastic rupture in the government’s policy and societal practice in water control. The concentration of power on the revolutionary government in the cities resulted in the decline of local organizations used to assume water control responsibility at the community level. They were replaced by centrally appointed modernist urban planners who were often ignorant about local condition and traditional wisdom and practice of water control.

description: In this paper we investigate a sequence of square integrable random processes with space varying memory. We establish sufficient conditions for the central limit theorem in the space $L^2(μ)$ for the partial sums of the sequence of random processes with space varying long memory. Of particular interest is a non-standard normalization of the partial sums in the central limit theorem.

description: We present the discovery of 816 high amplitude infrared variable stars ($ΔK_{\rm s} >$ 1 mag) in 119 deg$^2$ of the Galactic midplane covered by the Vista Variables in the Via Lactea (VVV) survey. Almost all are new discoveries and about 50$\%$ are YSOs. This provides further evidence that YSOs are the commonest high amplitude infrared variable stars in the Galactic plane. In the 2010-2014 time series of likely YSOs we find that the amplitude of variability increases towards younger evolutionary classes (class I and flat-spectrum sources) except on short timescales ($$100 days) and 162 short-term variables. Eruptive YSOs and faders tend to have the highest amplitudes and eruptive systems have the reddest SEDs. Follow up spectroscopy in a companion paper verifies high accretion rates in the eruptive systems. Variable extinction is disfavoured by the 2 epochs of colour data. These discoveries increase the number of eruptive variable YSOs by a factor of at least 5, most being at earlier stages of evolution than the known FUor and EXor types. We find that eruptive variability is at least an order of magnitude more common in class I YSOs than class II YSOs. Typical outburst durations are 1 to 4 years, between those of EXors and FUors. They occur in 3 to 6\% of class I YSOs over a 4 year time span.

description: Many consider organizational effectiveness the most critical dependent variable in all organizational analyses. The purpose of this study is to examine the components of organizational effectiveness in intercollegiate athletic departments, determine the best model of fit, and create a foundation grounded in the practical application which merges the theory with the reality. Ten individuals having carried the title of athletic director, or senior level administrator at the Power 5 level were selected to participate in this study. After examining the theoretical research and the four major models that have been developed over time, it was clear the fourth model, the multiple-constituency model, and its synthesis of the earlier three models is the best fit for this industry. This study contributes to the literature by delineating the core metrics utilized by athletic departments in their evaluation process which provides a launching point for future research into organizational effectiveness in intercollegiate athletics.

description: This work presents a new silicon vertical JFET (V-JFET) device, based on the trenched 3D-detector technology developed at IMB-CNM, to be used as switches for the High-Voltage powering scheme of the ATLAS upgrade Inner Tracker. The optimization of the device characteristics is performed by 2D and 3D TCAD simulations. Special attention has been paid to the on-resistance and the switch-off and breakdown voltages to meet the specific requirements of the system. In addition, a set of parameter values has been extracted from the simulated curves to implement a SPICE model of the proposed V-JFET transistor. As these devices are expected to operate under very high radiation conditions during the whole experiment life-time, a study of the radiation damage effects and the expected degradation on the device performance is also presented at the end of the paper.

description: Schule soll auf eine gesellschaftliche Teilhabe vorbereiten sowie einen Beitrag zur Persönlichkeitsbildung leisten. Im Spiegel einer religionspluralen Gesellschaft spitzen sich diese Aufgaben für den Religionsunterricht auf einen Doppelauftrag zu. Es geht (1.) darum, Orientierung zu bieten bzw. eine persönlichkeitsbildende Auseinandersetzung mit dem eigenen (Nicht-)Glauben (intra) zu initiieren und (2.) darum, für einen angemessenen Umgang mit religiöser Vielfalt zu befähigen sowie zu einem besseren Verständnis Andersgläubiger (inter) zu führen. Diese Perspektive ist im religionspädagogischen Paradigma des interreligiösen Lernens wesentlich. In diesen Kontext lässt sich auch der Synagogenbesuch als ein derzeit von LehrerInnen in der Praxis des Religionsunterrichts präferiertes Lernsetting einordnen, welches im Rahmen dieser empirischen Studie beforscht worden ist. Die Ergebnisse der Evaluationsstudie zu Synagogenexkursionen im Religionsunterricht der Oberstufe, die als qualitativ-quantitative Forschung im Rahmen einer einstellungsbezogenen Didaktik interreligiösen Lernens realisiert worden ist, zeigen auf, dass ein dringender Bedarf besteht, Konzepte des Vorurteilsabbaus bzw. von Einstellungsänderungen religionsdidaktisch neu zu denken.
