description: Turbulent fluid dynamics typically involves excitations on many different length scales. Classical incompressible fluids can be cleanly represented in Fourier space enabling spectral analysis of energy cascades and other turbulence phenomena. In quantum fluids, additional phase information and singular behaviour near vortex cores thwarts the direct extension of standard spectral techniques. We develop a formal and numerical spectral analysis for $U(1)$ symmetry-breaking quantum fluids suitable for analyzing turbulent flows, with specific application to the Gross-Pitaevskii fluid. Our analysis builds naturally on the canonical approach to spectral analysis of velocity fields in compressible quantum fluids, and establishes a clear correspondence between energy spectral densities, power spectral densities, and autocorrelation functions, applicable to energy residing in velocity, quantum pressure, interaction, and potential energy of the fluid. Our formulation includes all quantum phase information and also enables arbitrary resolution spectral analysis, a valuable feature for numerical analysis. A central vortex in a trapped planar Bose-Einstein condensate provides an analytically tractable example with spectral features of interest in both the infrared and ultraviolet regimes. Sampled distributions modelling the dipole gas, plasma, and clustered regimes exhibit velocity correlation length increasing with vortex energy, consistent with known qualitative behaviour across the vortex clustering transition. The spectral analysis of compressible quantum fluids presented here offers a rigorous tool for analysing quantum features of superfluid turbulence in atomic or polariton condensates.

description: Globally, the extraction of minerals and fossil fuels is increasingly penetrating into isolated regions inhabited by indigenous peoples, potentially undermining their livelihoods and well-being. To provide new insight to this issue, we draw on a unique longitudinal dataset collected in the Ecuadorian Amazon over an 11-year period from 484 indigenous households with varying degrees of exposure to oil extraction. Fixed and random effects regression models of the consequences of oil activities for livelihood outcomes reveal mixed and multidimensional effects. These results challenge common assumptions about these processes and are only partly consistent with hypotheses drawn from the Dutch disease literature.
The addition in conservation project for the accessibility to cultural heritage

Year: 2016

description: The topic of addition represents of the main cornerstones of the debate on conservation. It also represents the comparison between different orientations, that see on the one hand its legitimacy with regards to the contemporary language and, on the other, its denial in favor of a more or less consistent material subtraction. With reference to the accessibility of cultural heritage, the strategy of the addition is more suited for both instances of protection and accessibility by proposing a new technological layer of the contemporaneity thereby also becoming an act of democracy. The essay addresses, also through same examples, the issue by analyzing it under the profile of conservation and technology understood as an united approach to the existence, aimed at the preservation and enhancement of heritage.

description: This paper uses 620 forest plot measurements taken from a nationally representative sample of 130 Nepal community forests combined with information on forest collective action to estimate the effects of collective action on carbon per hectare and three additional measures of forest quality. We use three measures of forest user group collective action, including membership in the Nepal Community Forestry Programme (CFP). Collective action shows large, positive, and statistically significant carbon effects vis-à-vis communities exhibiting no evidence of forest collective action, which do not necessarily correspond with results for other measures of forest quality. We find that depending on the collective action definition and physiographic region, forests controlled by communities exhibiting no evidence of forest collective action may have as little as 34% of the carbon of forests governed under collective action. We do not, however, find evidence that CFP forests, our narrowest measure of collective action, store more carbon than forests outside the CFP. Our results therefore suggest that it is the collective action behavior and not the official CFP label that offers the largest gains. Carbon benefits from collective action are therefore not found to be conditional on CFP participation.

description: This paper examines several established urban contexts containing remnants from pre-existing industrial zones, now abandoned, but which are part of an original urban lay-out that needs to be reinterpreted, redeveloped and re-utilized to provide a possible alternative to the present urban sprawl. The project for transformation/change comprises an intervention methodology that demands appropriate approaches, sensitivity and tools, ranging from urbanistic to architectural control, from technological and structural to social and fruitive checks. Several design hypotheses are presented, illustrating how the enhancement of industrial zones may contribute to the urban regeneration of entire areas or parts of a city, whilst, at the same time, fostering recovery and economic growth throughout the area.

description: This study examines changes in religious service attendance over time for a contemporary cohort of adolescents moving from middle to late adolescence. We use two waves of a nationally representative panel survey of youth from the National Study of Youth and Religion (NSYR) to examine the dynamics of religious involvement during adolescence. We then follow with an analysis of how demographic characteristics, family background, and life course transitions relate to changes in religious service attendance during adolescence. Our findings suggest that, on average, adolescent religious service attendance declines over time, related to major life course transitions such as becoming employed, leaving home, and initiating sexual activity. Parents’ affiliation and attendance, on the other hand, are protective factors against decreasing attendance.
The Built Environment Plan 2.0

description: Around the mid 1980’s, the appealing perspective of the plan for built environment came out of the debate on the themes of building restoration. Since then different changes of cultural and normative context occurred. The contribution explores such dynamics, enucleating and deepening three matters - knowledge, responsibility, service life - that, in their trend, have contributed and still contribute to redraw scientific, technical and operational frontiers of relationship between maintenance and transformation. Thereby the paper faces some of the crux that allow a critical observation of the development dynamics of the idea, and of its meaning, concerns what is still today decodable as plan for built environment.

Musical predictors of acculturation and adaptation by international students in Australia
Creators: name: Quan, Yixue
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: When studying abroad, international students may or may not successfully adapt to the host society. Previous studies suggest that positive adaptation is generally associated with openness to experience and cultural values that align with the host culture. However, a person’s musical inclinations may also predict international students’ adaptation to new societies, given that music is a cultural medium that connects people of different backgrounds. This thesis examined whether two aspects of music listening behaviour – world music openearedness and uses of music – predict international students' psychological and sociocultural adaptation to Australian society. World music open-earedness refers to a willingness to explore, listen to, tolerate, and learn about music from diverse cultures. It was assessed by surveying people about 21 music excerpts from seven geographic regions. Uses of music refer to the goals of music listening and include using music to manage or optimize: (a) mood and emotion; (b) arousal and activation; (c) communication; (d) self-reflection; and (e) cultural expression. 77 international students in Australia (54 females, mean age=24.83 years) completed an online survey. To control the influence of demographics, personality, and cultural values on adaptation outcomes, hierarchical regressions and model reductions with AIC backward elimination were conducted. Results showed that international students with higher tolerance to world music had greater levels of psychological adaptation, after demographic data, personality, and collectivist values were controlled. High world music open-earedness was associated with fewer difficulties in sociocultural adaptation. Among the five uses of music, using music for communication and self-reflection were positively related to psychological adaptation. Mechanisms that account for these associations, and implications for identifying at-risk international students, are discussed. New music programs are also proposed to enhance the cultural experiences of international students in Australia. The current findings demonstrate that the power of music is far more than just aesthetic enjoyment and may even help people adjust to new societies.

description: The existing publications demonstrate that the limit order book data is useful in predicting short-term volatility in stock markets. Since stocks are not independent, changes on one stock can also impact other related stocks. In this paper, we are interested in forecasting short-term realized volatility in a multivariate approach based on limit order book data and relational data. To achieve this goal, we introduce Graph Transformer Network for Volatility Forecasting. The model allows to combine limit order book features and an unlimited number of temporal and cross-sectional relations from different sources. Through experiments based on about 500 stocks from S&P 500 index, we find a better performance for our model than for other benchmarks.

description: While it is well understood that adolescent religiosity is associated with the use and abuse of licit and illicit substances, few studies have revealed the pathways through which religiosity buffers youth against involvement in such behavior. The aim of this study is to examine the complexity of the relationships between religiosity, sensation seeking, injunctive norms, and adolescent substance use. Using a national sample of adolescents (N = 18,614), negative binomial regression and path analysis were used to examine the various components of the relationship between religiosity and the use of cigarettes, alcohol, and marijuana. Results indicate that private religiosity moderates the relationship between key risk factors and substance use. Public and private religiosity were associated with tolerant injunctive substance use norms which, in turn, were associated with substance use. Implications for research and theory related to religiosity and adolescent substance use are discussed.

description: After the rediscovery of the historical city by the Italian urban analysis of the fifties and sixties and the following European urban projects of critical reconstruction, it arises a new awareness of the historical city as an artifact built over time and the possibility of its continuity. This recovered temporal condition of consolidated contexts defines the margin within which it is defined the architectural design of urban living, here exemplified through some didactic experiments carried out in two cities (Berlin and Milan). Among the ways of interventions, almost in a surgical manner, emerges on often-unresolved urban sites the thematic confrontation with the urban block and the townhouse, intended as the minimum element of the architecture of the city.

description: We present a magneto-infrared spectroscopy study on a newly identified three-dimensional (3D) Dirac semimetal ZrTe$_5$. We observe clear transitions between Landau levels and their further splitting under magnetic field. Both the sequence of transitions and their field dependence follow quantitatively the relation expected for 3D \emph{massless} Dirac fermions. The measurement also reveals an exceptionally low magnetic field needed to drive the compound into its quantum limit, demonstrating that ZrTe$_5$ is an extremely clean system and ideal platform for studying 3D Dirac fermions. The splitting of the Landau levels provides a direct and bulk spectroscopic evidence that a relatively weak magnetic field can produce a sizeable Zeeman effect on the 3D Dirac fermions, which lifts the spin degeneracy of Landau levels. Our analysis indicates that the compound evolves from a Dirac semimetal into a topological line-node semimetal under current magnetic field configuration.

description: We develop an action formulation of stochastic dynamics in the Hilbert space. By generalizing the Wiener process into 1+3-dimensional spacetime, we define a Lorentz-invariant random field. By coupling the random to quantum fields, we obtain a random-number action which has the statistical spacetime translation and Lorentz symmetries. The canonical quantization of the theory results in a Lorentz-invariant equation of motion for the state vector or density matrix. We derive the path integral formula of $S$-matrix and the diagrammatic rules for both the stochastic free field theory and stochastic $ϕ^4$-theory. The Lorentz invariance of the random $S$-matrix is strictly proved. We then develop a diagrammatic technique for calculating the density matrix. Without interaction, we obtain the exact $S$-matrix and density matrix. With interaction, we prove a simple relation between the density matrices of stochastic and conventional $ϕ^4$-theory. Our formalism leads to an ultraviolet divergence which has the similar origin as that in QFT. The divergence is canceled by renormalizing the coupling strength to random field. We prove that the stochastic QFT is renormalizable even in the presence of interaction. In the models with a linear coupling between random and quantum fields, the random field excites particles out of the vacuum, driving the universe towards an infinite-temperature state. The number of excited particles follows the Poisson distribution. The collision between particles is not affected by the random field. But the signals of colliding particles are gradually covered by the background excitations caused by random field.

description: As the baby-boom generation continues to retire in large numbers, the migration of retirees to new areas in search of a better quality of life has become an increasingly visible phenomenon. This project examines the impact of retiree migration on the job quality of regions receiving retired migrants. Using publicly available data and an econometric research design, this analysis finds a positive and significant relationship between retiree migration and employment growth in low-wage service industries. Complementing this finding is a discussion on potential strategies for policy-makers to capitalize on opportunities from retiree in-migration for economic and community development.

description: Synchronization is an important and prevalent phenomenon in natural and engineered systems. In many dynamical networks, the coupling is balanced or adjusted in order to admit global synchronization, a condition called Laplacian coupling. Many networks exhibit incomplete synchronization, where two or more clusters of synchronization persist, and computational group theory has recently proved to be valuable in discovering these cluster states based upon the topology of the network. In the important case of Laplacian coupling, additional synchronization patterns can exist that would not be predicted from the group theory analysis alone. The understanding of how and when clusters form, merge, and persist is essential for understanding collective dynamics, synchronization, and failure mechanisms of complex networks such as electric power grids, distributed control networks, and autonomous swarming vehicles. We describe here a method to find and analyze all of the possible cluster synchronization patterns in a Laplacian-coupled network, by applying methods of computational group theory to dynamically-equivalent networks. We present a general technique to evaluate the stability of each of the dynamically valid cluster synchronization patterns. Our results are validated in an electro-optic experiment on a 5 node network that confirms the synchronization patterns predicted by the theory.

description: The paradigm of the healthy city defined by the World Health Organization may present an important occasion for redefining the relationship between conservation and transformation in small cities, working not only with enduring built capital, but also employing ecological, social, cultural and economic capital. A possible horizon of innovation may be identified in the search for improved conditions in the city, working with open spaces as a super-system of reconnections to recompose the processes, productivity and diversity that, while currently interrupted, once existed between city and territory. The result would be small healthy cities that favour the return of an active and healthy lifestyle for users and offer an alternative to the standardised conditions of the metropolis.

Fountain Codes with Nonuniform Selection Distributions through Feedback

description: One key requirement for fountain (rateless) coding schemes is to achieve a high intermediate symbol recovery rate. Recent coding schemes have incorporated the use of a feedback channel to improve intermediate performance of traditional rateless codes; however, these codes with feedback are designed based on uniformly at random selection of input symbols. In this paper, on the other hand, we develop feedback-based fountain codes with dynamically-adjusted nonuniform symbol selection distributions, and show that this characteristic can enhance the intermediate decoding rate. We provide an analysis of our codes, including bounds on computational complexity and failure probability for a maximum likelihood decoder; the latter are tighter than bounds known for classical rateless codes. Through numerical simulations, we also show that feedback information paired with a nonuniform selection distribution can highly improve the symbol recovery rate, and that the amount of feedback sent can be tuned to the specific transmission properties of a given feedback channel.

description: In the era of noisy intermediate-scale quantum (NISQ) devices, the number of controllable hardware qubits is insufficient to implement quantum error correction (QEC). As an alternative, quantum error mitigation (QEM) can suppress errors in measurement results via repeated experiments and postprocessing of data. Typical techniques for error mitigation, e.g., the quasi-probability decomposition method, ignore correlated errors between different gates. Here, we introduce a QEM method based on the matrix product operator (MPO) representation of a quantum circuit that can characterize the noise channel with polynomial complexity. Our technique is demonstrated on a $\rm{depth}=20$ fully parallel quantum circuit of up to $N_q=20$ qubits undergoing local and global noise. The circuit error is reduced by several times with only a small bond dimension $D^{\prime} = 1$ for the noise channel. The MPO representation increases the accuracy of modeling noise without consuming more experimental resources, which improves the QEM performance and broadens its scope of application. Our method is hopeful of being applied to circuits in higher dimensions with more qubits and deeper depth.

description: Objectives. This research seeks to understand the internal and external determinants of state level diffusion for lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) nondiscrimination policy for both youth and adults involved with the child welfare system. Methods. I utilized a pooled event history analysis (PEHA) to understand the determinants of diffusion. This allows me to understand multiple, rarely adopted policies in a single model. Results. This study found internal determinants to be significant in the adoption of these policies. Results also demonstrated that the content of policy in the same area could have different determinants. Conclusions. Future policy research should consider these results when designing future studies and advocates wishing to expand LGBTQ rights could use this as a starting point in their advocacy work.

description: Machine learning, with its advances in deep learning has shown great potential in analyzing time series. In many scenarios, however, additional information that can potentially improve the predictions is available. This is crucial for data that arise from e.g., sensor networks that contain information about sensor locations. Then, such spatial information can be exploited by modeling it via graph structures, along with the sequential (time series) information. Recent advances in adapting deep learning to graphs have shown potential in various tasks. However, these methods have not been adapted for time series tasks to a great extent. Most attempts have essentially consolidated around time series forecasting with small sequence lengths. Generally, these architectures are not well suited for regression or classification tasks where the value to be predicted is not strictly depending on the most recent values, but rather on the whole length of the time series. We propose TISER-GCN, a novel graph neural network architecture for processing, in particular, these long time series in a multivariate regression task. Our proposed model is tested on two seismic datasets containing earthquake waveforms, where the goal is to predict maximum intensity measurements of ground shaking at each seismic station. Our findings demonstrate promising results of our approach -- with an average MSE reduction of 16.3% - compared to the best performing baselines. In addition, our approach matches the baseline scores by needing only half the input size. The results are discussed in depth with an additional ablation study.

description: We study a Bose-Einstein condensate of ultracold atoms subject to a non-Hermitian spin-orbit coupling, where the system acquires non-Hermitian skin effect under the interplay of spin-orbit coupling and laser-induced atom loss. The presence of the non-Hermitian skin effect is confirmed through its key signatures in term of the spectral winding under the periodic boundary condition, the accumulation of eigen wavefunctions at boundaries under an open boundary condition, as well as bulk dynamics signaled by a directional flow. We show that the bulk dynamics in particular serves as a convenient signal for experimental detection. The impact of interaction and trapping potentials are also discussed based on non-Hermitian Gross-Pitaevskii equations. Our work demonstrates that the non-Hermitian skin effect and its rich implications in topology, dynamics and beyond are well within reach of current cold-atom experiments.

description: We study the effects of oblateness up to $J_4$ of the primaries and power-law density profile (PDP) on the linear stability of libration location of an infinitesimal mass within the framework of restricted three body problem (R3BP), by using a more realistic model in which a disc with PDP is rotating around the common center of the system mass with perturbed mean motion. The existence and stability of triangular equilibrium points have been explored. It has been shown that triangular equilibrium points are stable for $0

description: From 10 to 26 February 2006 Turin hosted the XX Olympic Winter Games. The building process of all the necessary infrastructure has been characterized, since the design phase, by exceptional measures for quality control and for environmental protection. The settlement of the "Olympic District" in Turin, in the Lingotto area has represented, since the beginning, an opportunity for the re-develop of an historical urban area. Ten years after the event, the Olympic Village area is in a state of strong urban decay, at the building and the social level. The re-conversion had a negative result. The contribution identifies the critical points that brought the project so far away from the original aims, despite the innovative methods of control and management of the process.

description: In Pakistan, the popularity of the internet has changed the media dynamics and has transformed their characteristics. In Pakistan, the use of digital media has advanced tremendously, which is why Pakistani journalists are utilizing mobile phones as a journalistic tool to explain their stories in different styles. For all these reasons, this research study will investigate the techniques and practices of journalists as they use mobile phones for journalism.
 This research paper will covered journalistic storytelling via mobile phones, which will be based on a methodological investigation of mobile journalism techniques or methods for journalists. This analysis will analyze the ways reporters interpret their own beat storis through mobile phones. A detailed questionnaire will be filled by journalists who use mobile as a journalistic tool for their stories. This research study will shed light on the characteristics of mobile journalism in Pakistan, how they use mobile for journalism and how it differs from ournalists working for TV.

description: There is a growing body of research connecting the built environment, such as housing and transportation, to health outcomes. Although there are obvious connections between some of these topics, such as the way indoor and outdoor air quality may affect respiratory health, there are also less established pathways between policy decisions and the health of a population. A Health Impact Assessment (HIA) is one way to determine the potential health impacts of a proposed policy, project, or program before implementation in order to recommend changes that will protect and promote health. HIAs can be an especially useful tool to use when a new policy, project, or program may have substantial impacts on a vulnerable population, such as tenants of public housing. Many housing authorities throughout the United States are beginning to implement the Rental Assistance Demonstration (RAD) Program, a federal program aimed at improving America’s stock of public housing by converting current public housing units to project-based Section 8 assistance. Through the RAD Program, public housing authorities can position themselves to tap into private sources of funding for real estate, including bank loans, bond proceeds, and tax-credit equity, that can be used to renovate or build new units. The RAD Program removes the current funding restrictions faced by public housing authorities. The RAD Program has been expanding rapidly over the last several years; however, very little research has been done to determine the impacts this program will have on current public housing residents. The Durham Housing Authority is planning to convert its entire portfolio of public housing units to project-based Section 8 assistance under the RAD Program and is interested in identifying ways this conversion may impact tenants, both positively and negatively. Therefore, the purpose of this HIA was to determine how the RAD Program will impact the health of Durham Housing Authority residents and to recommend ways to protect and promote health for this population.

description: The demand to adapt the urban amenities to increasingly complex settlement needs, articulated and oriented to the energy efficiency of buildings, led to the need to undertake operational strategies to meet the existing challenges, developing projects for the transformation of the urban, historical or marginal environment. Some recent experiences of urban regeneration, increasingly declined towards an idea of compact and dense city, are meeting new energy settings, mobility, social inclusion, sustainable development. The role of technology choices appears crucial to the quality of interventions in areas of compromised material and immaterial integrity, that can become a research object for new eco-oriented design approaches.
