A study of migration to and from Beijing
Creators: name: Lin, You Su
Publisher: name: The Australian National University
Year: 1986
Subjects: subject: Migration, Internal China Beijing
subject: Beijing (China) Population

description: The objective of this study is to examine the migration pattern and characteristics of migrants in Beijing during the period of 1950-1983 and of recent out-migrants from Beijing. The study is based on two kinds of data; one is the migration survey data of Beijing in 1984, the other is the registration data for Beijing (1950-1983). The thesis is divided into six chapters. Chapter 1 provides a general background of the study and the study area. Chapter 2 reviews the literature on migration and serves as a theoretical framework for the thesis. In Chapter 3, the study reviews the migration trend and pattern in Beijing from 1950 to 1983. It also examines the relationship between migration and economic development. In Chapter 4 and Chapter 5, the study discusses the social and economic characteristics of in-migrants to Beijing and out-migrants from Beijing and compares these characteristics with those of non-migrants. The study also tries to assess the validaty of certain hypotheses on internal migration in the context of Beijing. Finally, Chapter 6 provides some conclusions about migration to Beijing. It also puts forward some suggestions for further study on migration in China.

description: This study is based on the 1984 Malawi Family Formation Survey, a nationwide sample survey conducted by the National Statistical Office in collaboration with the Ministry of Health. The study has attempted to examine variations in infant and child mortality by demographic and socio-economic variables using unweighted data for the Southern Region only. Children were the unit of analysis and probabilities of dying in infancy or childhood were calculated by the various variables. The results indicate that both infant and child mortality is highest among children of teenagers. Differences by sex were not statistically significant. Moreover, infant and child mortality is higher among first order and high order births than among births of second or third order. Furthermore, mortality declines as the length of the birth interval increases. Also, twins had higher infant and child mortality than singletons. Infant and child mortality declined as the mother's education increased. Similar results were found when the education of the mother's current or last husband (if widowed, divorced/separated) was used. Rural areas have higher infant and child mortality than urban areas. Households using facilities like piped water, flush toilet and owning a radio in working condition have lower infant and child mortality than those that use other sources of drinking water, have a pit latrine or none and have no radio. Health care factors like mother's medical check during pregnancy, place of birth, birth attendant and immunisation also influence infant and child mortality.

description: Two fits of the pairing residual interaction in the rare-earth region are independently performed. One is made on the odd-even staggering of masses by comparing measured and explicitly calculated three-point binding-energy differences centered on odd-even nuclei. Another deals with the moments of inertia of the first 2+ states of well deformed even-even nuclei upon comparing experimental data with the results of Inglis-Belyaev moments (supplemented by a crude estimate of the so-called Thouless-Valatin corrections). The sample includes 24 even-even and 31 odd-mass nuclei selected according to two criteria: they should have good rotor properties and should not correspond to low pairing-correlation regimes in their ground states. Calculations are performed in the self-consistent Hartree-Fock plus BCS framework (implementing a self-consistent blocking in the case of odd-mass nuclei). The Skyrme SIII parametrization is used in the particle-hole channel and the fitted quantities are the strengths of |Tz|=1 proton and neutron seniority residual interactions. As a result, the two fits yield sets of strengths in excellent agreement: about 0.1% for the neutron parameters and 0.2% for protons. In contrast when one performs such a fit on odd-even staggering from quantities deduced from BCS gaps or minimal quasiparticle energies in even-even nuclei, as is traditional, one obtains results significantly different from those obtained in the same nuclei by a fit of moments of inertia. As a conclusion, beyond providing a phenomenological tool for microscopic calculations in this region, we have illustrated the proposition made in the seminal paper of Bohr, Mottelson and Pines that moments of inertia and odd-even staggering in selected nuclei were excellent measuring sticks of nuclear pairing correlations.

description: We compute the leading probability for a gluon to flip helicity state upon traversing a background plane wave gauge field in pure Yang-Mills theory and QCD, with an arbitrary number of colours and flavours. This is a one-loop calculation in perturbative gauge theory around the gluonic plane wave background, which is treated without approximation (i.e., to all orders in the coupling). We introduce a background-dressed version of the spinor helicity formalism and use it to obtain simple formulae for the flip amplitude with pure external gluon polarizations. We also give in-depth examples for gauge group SU(2), and evaluate both the high- and low-energy limits. Throughout, we compare and contrast with the calculation of photon helicity flip in strong-field QED.

description: The one-dimensional Schrodinger equation for the potential $x^6+αx^2 +l(l+1)/x^2$ has many interesting properties. For certain values of the parameters l and alpha the equation is in turn supersymmetric (Witten), quasi-exactly solvable (Turbiner), and it also appears in Lipatov's approach to high energy QCD. In this paper we signal some further curious features of these theories, namely novel spectral equivalences with particular second- and third-order differential equations. These relationships are obtained via a recently-observed connection between the theories of ordinary differential equations and integrable models. Generalised supersymmetry transformations acting at the quasi-exactly solvable points are also pointed out, and an efficient numerical procedure for the study of these and related problems is described. Finally we generalise slightly and then prove a conjecture due to Bessis, Zinn-Justin, Bender and Boettcher, concerning the reality of the spectra of certain PT-symmetric quantum-mechanical systems.

description: We demonstrate the use of a hybrid $^{3}$He / $^{87}$Rb magnetometer to measure absolute magnetic fields in the pT range. The measurements were undertaken by probing time-dependent $^3$He magnetisation using $^{87}$Rb zero-field magnetometers. Measurements were taken to demonstrate the use of the magnetometer in cancelling residual fields within a magnetic shield. It was shown that the absolute field could be reduced to the 10 pT level by using field readings from the magnetometer. Furthermore, the hybrid magnetometer was shown to be applicable for the reduction of gradient fields by optimising the effective $^3$He $T_2$ time. This procedure represents a convenient and consistent way to provide a near zero magnetic field environment which can be potentially used as a base for generating desired magnetic field configurations for use in precision measurements.

description: We analyze quantum correlation properties of a spinor-1 (f=1) Bose Einstein condensate using the Gell-Mann realization of SU(3) symmetry. We show that previously discussed phenomena of condensate fragmentation and spin-mixing can be explained in terms of the hypercharge symmetry. The ground state of a spinor-1 condensate is found to be fragmented for ferromagnetic interactions. The notion of two bosonic mode squeezing is generalized to the two spin (U-V) squeezing within the SU(3) formalism. Spin squeezing in the isospin subspace (T) is found and numerically investigated. We also provide new results for the stationary states of spinor-1 condensates.

description: Background Relationship status is an important factor associated with condomless anal intercourse (CAI) amongst men who have sex with men (MSM). Methods A multi-centre bio-behavioural survey with MSM was conducted in 13 European cities (n = 4901) exploring factors associated with CAI via bivariate and multivariate multilevel logistic regression analyses. Results Likelihood of CAI with casual partners was associated with being ‘out’ to a majority (AOR = 1.19;95% CI 1,1.42); knowing their HIV status (AOR = 1.86; 95% CI 1.25,2.76); using substances (1–2 AOR = 1.39; 95% CI 1.16,1.63, 2+ AOR = 1.81; 95% CI 1.35,2.42); being older (AOR = 0.98; 95% CI 0.97,0.99); successful sero-communication (AOR = 0.79; 95% CI 0.67,0.94); and, not having a recent HIV test (AOR = 0.78; 95% CI 0.66,0.92). CAI with steady partners was associated with successful sero-communication (AOR = 2.72; 95% CI 2.72,3.66); not having a recent HIV test (AOR = 1.26; 95% CI 1.09,1.46), and; being older (AOR = 0.99; 95% CI 0.98,0.99). Conclusions Understandings of partner type and/or relationship status in relation to CAI amongst MSM can potentially play an important role in the development of culturally appropriate HIV/STI prevention and risk-reduction efforts targeting at-risk MSM. Our results speak to the need to consider segmented and tailored public health and health promotion initiatives for MSM with differing CAI behaviours and relationship profiles.

description: ABSTRACT

       This study conducts a systematic evaluation of modern technology use in construction project management based on Mogadishu, Somalia. Rapid urbanization and infrastructure development in Mogadishu necessitate the efficient utilization of modern technologies to address construction challenges and improve project outcomes. Through a comprehensive analysis of current practices, challenges, and opportunities, this evaluation aims to provide insights and recommendations for enhancing technology adoption in the construction industry/Companies. The evaluation encompasses an examination of the existing technology landscape in Mogadishu, including the adoption patterns of modern tools such as Building Information Modeling (BIM), project management software, and digital communication platforms. Challenges and barriers hindering technology adoption, including infrastructure limitations, skills gaps, and regulatory constraints, are identified and analyzed.

        Opportunities for improvement, including strategies for infrastructure development, capacity building, and stakeholder engagement, are explored to facilitate the effective integration of modern technologies into construction practices. A cost-benefit analysis is conducted to assess the financial and non-financial implications of technology adoption, considering factors such as project efficiency, quality, and environmental sustainability.

Questionnaire survey and best practices focusing on Construction Companies, senior and Juniors Engineers from Mogadishu and similar contexts are examined to extract lessons learned and inform recommendations for implementation. These recommendations encompass actionable strategies for enhancing technology adoption, addressing regulatory compliance, and fostering a culture of innovation in construction project management. By addressing these key aspects, this systematic evaluation contributes to the advancement of technology use in construction project management in Mogadishu, Somalia. The findings and recommendations presented in this study serve as a valuable resource for construction stakeholders, policymakers, and researchers seeking to optimize technology use and drive sustainable development in the region's construction Companies.

description: In these lectures, we discuss the influence of weak quenched disorder on the critical behavior in condensed matter and give a brief review of available experimental and theoretical results as well as results of MC simulations of these phenomena. We concentrate on three cases: (i) uncorrelated random-site disorder, (ii) long-range-correlated random-site disorder, and (iii) random anisotropy. Today, the standard analytical description of critical behavior is given by renormalization group results refined by resummation of the perturbation theory series. The convergence properties of the series are unknown for most disordered models. The main object of these lectures is to discuss the peculiarities of the application of resummation techniques to perturbation theory series of disordered models.

description: For a class of convection-diffusion equations with variable diffusivity, we construct third order accurate discontinuous Galerkin (DG) schemes on both one and two dimensional rectangular meshes. The DG method with an explicit time stepping can well be applied to nonlinear convection-diffusion equations. It is shown that under suitable time step restrictions, the scaling limiter proposed in [Liu and Yu, SIAM J. Sci. Comput. 36(5): A2296{A2325, 2014] when coupled with the present DG schemes preserves the solution bounds indicated by the initial data, i.e., the maximum principle, while maintaining uniform third order accuracy. These schemes can be extended to rectangular meshes in three dimension. The crucial for all model scenarios is that an effective test set can be identified to verify the desired bounds of numerical solutions. This is achieved mainly by taking advantage of the flexible form of the diffusive flux and the adaptable decomposition of weighted cell averages. Numerical results are presented to validate the numerical methods and demonstrate their effectiveness.
Experimental studies of plasma confined in a toroidal heliac

Subjects: subject: Plasma confinement

description: This thesis describes in detail the properties of and experimental results obtained on the first toroidal heliac (helical axis stellarator) SHEILA. The machine construction, operation and the Langmuir probe diagnostics used in these experiments are described. Computational results for the wide range of vacuum configurations made accessible by the addition of a helical winding to the basic heliac coil configuration are presented and discussed. The main part of this thesis is dedicated to the study of a low beta argon plasma (ß ~ 10-4) confined in various heliac configurations. The existence of plasma equilibrium surfaces is verified experimentally. Observations of phenomena associated with magnetic surface resonances, e.g. the deterioration of plasma confinement when the rotational transform profile includes certain low-order rational surfaces, are described. Some features associated with the surface destruction and the magnetic island formation appear in both plasma pressure and floating potential profiles. A known symmetry-breaking error in coil position is shown to have significant effect on the vacuum magnetic configurations. Low frequency coherent fluctuations in plasma density, floating potential and magnetic field are studied for three typical heliac configurations. Spatial mode structures are analyzed in a magnetic coordinate system. The measured frequencies and wavenumbers of the fluctuations, together with their parametric dependences on the magnetic field and the electron collision frequency, are compared with a collisional drift wave model. The agreement is excellent. The model is derived from a linearized two-fluid theory and related through an appropriate magnetic coordinate transformation to the heliac geometry. The influence of these fluctuations on the observed particle confinement is briefly discussed.

description: Connes' functional formula of the Riemannian distance is generalized to the Lorentzian case using the so-called Lorentzian distance, the d'Alembert operator and the causal functions of a globally hyperbolic spacetime. As a step of the presented machinery, a proof of the almost-everywhere smoothness of the Lorentzian distance considered as a function of one of the two arguments is given. Afterwards, using a $C^*$-algebra approach, the spacetime causal structure and the Lorentzian distance are generalized into noncommutative structures giving rise to a Lorentzian version of part of Connes' noncommutative geometry. The generalized noncommutative spacetime consists of a direct set of Hilbert spaces and a related class of $C^*$-algebras of operators. In each algebra a convex cone made of self-adjoint elements is selected which generalizes the class of causal functions. The generalized events, called {\em loci}, are realized as the elements of the inductive limit of the spaces of the algebraic states on the $C^*$-algebras. A partial-ordering relation between pairs of loci generalizes the causal order relation in spacetime. A generalized Lorentz distance of loci is defined by means of a class of densely-defined operators which play the rôle of a Lorentzian metric. Specializing back the formalism to the usual globally hyperbolic spacetime, it is found that compactly-supported probability measures give rise to a non-pointwise extension of the concept of events.

description: It was observed recently that relations between matrix elements of certain operators in the $\text{SL}(2,\mathbb R)$ spin chain models take the form of multidimensional integrals derived by R.A. Gustafson. The spin magnets with $\text{SL}(2,\mathbb C)$ symmetry group and $\text{L}_2(\mathbb C)$ as a local Hilbert space give rise to a new type of $\Gamma$-function integrals. In this work we present a direct calculation of two such integrals. We also analyse properties of these integrals and show that they comprise the star--triangle relations recently discussed in the literature. It is also shown that in the quasi-classical limit these integral identities are reduced to the duality relations for Dotsenko-Fateev integrals.

description: We present measurements of the abundances of chromium, cobalt, and nickel in 4113 red giants, including 2277 stars in globular clusters, 1820 stars in the Milky Way's dwarf satellite galaxies, and 16 field stars. We measured the abundances from mostly archival Keck/DEIMOS medium-resolution spectroscopy with a resolving power of R ~ 6500 and a wavelength range of approximately 6500-9000 A. The abundances were determined by fitting spectral regions that contain absorption lines of the elements under consideration. We used estimates of temperature, surface gravity, and metallicity that we previously determined from the same spectra. We estimated systematic error by examining the dispersion of abundances within mono-metallic globular clusters. The median uncertainties for [Cr/Fe], [Co/Fe], and [Ni/Fe] are 0.20, 0.20, and 0.13, respectively. Finally, we validated our estimations of uncertainty through duplicate measurements, and we evaluated the accuracy and precision of our measurements through comparison to high-resolution spectroscopic measurements of the same stars.

description: We discuss the implication of the introduction of an extra field to the dynamics of a scalar field conformally coupled to gravitation in a homogeneous isotropic spatially flat universe.

Nevertheless for other parameter values new dynamical effects are obtained.
The relationship between household environmental factors and infant mortality rate in North Sumatra

Publisher: name: The Australian National University
Year: 1989
Subjects: subject: Infants MortalityIndonesia Sumatera Utara

description: Using the five per cent sample of the 1980 population census in North Sumatra, this study examines the relationship between household environmental factors and Infant Mortality Rate (IMR). The environmental factors are measured by the variables provided in the census data set: source of drinking water; floor area per member of household; and lavatory facility. In order to also observe the impact of socio-economic status of the households, some socio-economic factors are used. The theoretical framework proposed by Mosley and Chen (1984) is used in this study, in order to indicate the linkage of the variables. However, not all of the factors in their model are included in the study due to the incompleteness of the census data. The IMRs are estimated using the Trussell method of indirect estimation. It is assumed that the mortality pattern in Indonesia follows the 'West' model of Coale- Demeny model life tables. The values for IMRs are obtained through the measure of q3 (probability of dying between age 0 and age three) which is proved to be the best estimate from the data analysis. It is found that households which used piped-water as the source of drinking water had the lowest IMR. On the other hand, the highest IMR occurred among the households that used river-water as the source of drinking water. About 18 per cent of the households in rural areas still used river-water as the source of drinking water, while pipedwater was mainly available in urban areas. The findings also show that the relationship between crowding, which is measured by floor space per person, and IMR is different from what was expected. This finding was possibly due to the fact that the traditional houses, which are larger, are usually made of lower quality housing materials. However, after controlling for the highest category of socio-economic variables it shows negative relation (the larger the room space per person, the lower the IMR). This means that the positive relationship only occurred for those of low socio-economic status. Finally, it seems that the government of North Sumatra needs to provide or to encourage the use of lavatory facilities with septic-tanks in every household because it is found that with better lavatory facilities lower IMR's can be expected. The findings also show that the source of drinking water and the presence of lavatory facilities are factors in reducing IMR. Nevertheless, the improvement of maternal education, especially for those with little or no primary school education, and the provision of houses made of good materials could also help to reduce the level of infant mortality in North Sumatra.

description: In this thesis, we discuss the use of bootstrap methods for constructing confidence intervals in a wide variety of circumstances. In particular, we provide asymptotic theory for bootstrap confidence intervals based on Edgeworth expansions in several problems, and develop a general bootstrap resampling scheme applicable to a large range of statistical problem s. The thesis is divided into five chapters. The first gives a brief introduction to bootstrap methods and Edgeworth expansion theory to provide a background and motivation for our later work.

Geometrical Destabilisation of Ultra-Light Axions in String Inflation

description: We perform a detailed analytical and numerical analysis of the multi-field evolution of Fibre Inflation and show that, regardless of the microscopic realisation of the model, the mass-squared of one of the two ultra-light axions becomes always negative during inflation. This implies that the corresponding isocurvature perturbations experience a potential geometrical destabilisation which seems to bring the system away from the perturbative regime. Therefore we conclude that a full understanding of the inflationary evolution of Fibre Inflation can be achieved only via a non-perturbative analysis where the backreaction of tachyonic isocurvature perturbations is properly taken into account.

description: ヒップホップは, アメリカで1970年代初頭に生まれた, まだ歴史の短い音楽のジャンルの1つである. そのため, 日本国内ではまだメジャーとは言えない音楽ジャンルである. 

そこで本稿では, ユーザが自分の好きなポピュラー楽曲を指定すると, それをヒップホップ風に編曲するシステムを実現することで, ヒップホップをより身近な存在にすることを最終目標とする. 

編曲方法として, ポピュラー楽曲から歌唱部分を抜き出し, オーディオとして用意された素材を重畳する方法が考えられる. 音源分離, ビート推定, 音源伸縮などの技術が発達したことで, 比較的容易に実現できる. 実際, 異なる既存曲からドラムやピアノなどを抽出し, 組み合わせることで新たな曲を作成するというマッシュアップ音源作成などの自動化の研究も進められている. しかし, ビートやテンポの推定は必ずしも完全ではなく, 誤差が生じる可能性がある. 

本稿では, ヒップホップの一種のドリルに着目し, 歌唱音源と重畳したドラム音源に誤差があった場合に, それが知覚できるかを検証する. 2つの音源の発音タイミングが同時のものと, ずれたものを聴き, ずれている方を選ぶ実験を行った研究がある. この研究では, ピアノとストリングスとドリルを用いていた. ドリルは独特のリズム感があるため, 他のジャンルとは異なる傾向を示す可能性がある. そこで, ドリルのスタイルのドラム音源を用いて実験する. 

本稿では, ヒップホップ風編曲実現に向けて, ポピュラー楽曲の歌唱部とヒップホップのドラム音源の合成の際に, 歌唱部のテンポを段階的に変えて合成を行った音源を聴取し, ズレを知覚できるかの評価をする実験を行った. 実験に使用する音源は, ポピュラー楽曲のテンポをPythonの音楽解析, 信号処理のライブラリlibrosaを用いて推定し, そのテンポを利用して音源分離ツールSpleeterを用いて抽出したポピュラー楽曲の歌唱部のテンポをヒップホップのドラム音源のテンポにlibrosaを用いて変更し, テンポを変更した歌唱部とドラム音源を重畳し作成した. また音源作成のテンポ変更の際に, librosaを用いて推定したテンポを0.005倍ずつ速くしたり遅くしたりすることで, テンポがずれた音源を作成した. また実際のテンポに近いテンポを知るために, テンポが元から公開されている曲を用いて正確性を確認済みである音楽分析・編集サイト「ボーカルリムーバー」の「bpm計測」を用いた. 

実験の結果, 正確なテンポに近いテンポを用いた音源は, ずれていないと言う評価を得た. また歌唱部のテンポが僅かにずれるだけでも, ずれていると言う評価が多くなり, 僅かなテンポのずれでも知覚できることが分かった. またテンポを0.005倍速くなるか, 遅くなるかで評価の結果に差があり, テンポ間に非対称性があることが分かった. 今後は, 正確なテンポの検出方法やシンセサイザーやベースなどの合成方法について研究を進め, 自動編曲システムの実現を目指す.

description: Distributed antenna selection for Distributed Massive MIMO (Multiple Input Multiple Output) communication systems reduces computational complexity compared to centralised approaches, and provides high fault tolerance while retaining diversity and spatial multiplexity. We propose a novel distributed algorithm for antenna selection and show its advantage over existing centralised and distributed solutions. The proposed algorithm is shown to perform well with imperfect channel state information, and to execute a small number of simple computational operations per node, converging fast to a steady state. We base it on Reversing Petri Nets, a variant of Petri nets inspired by reversible computation, capable of both forward and backward execution while obeying conservation laws.

description: Deliverable D6.1 describes CUTLER’s approach for the analysis of the social impact of public administration policies related to the water element in waterfront cities. It discusses the necessary methodology that would reflect the opinion of the society with regard to policy implementation in such cities. In this regard, we propose an extensive approach to detect the trends and provide historical analysis from news articles comments, Twitter feeds, and events. More specifically, the approach includes the components of information filtering, extraction and analytics. Filtering techniques are essential to remove irrelevant data before information extraction and analytics. The information extraction techniques will be used to obtain the most relevant information from news articles, event logs, and social media feeds. The analytics process will apply text mining, spatio-temporal analysis, and sentiment analysis methods to induce relevant knowledge about social behavior, trends, and opinion.
Fraction of uninfected walkers in the one-dimensional Potts model

description: The dynamics of the one-dimensional q-state Potts model, in the zero temperature limit, can be formulated through the motion of random walkers which either annihilate (A + A -> 0) or coalesce (A + A -> A) with a q-dependent probability. We consider all of the walkers in this model to be mutually infectious. Whenever two walkers meet, they experience mutual contamination. Walkers which avoid an encounter with another random walker up to time t remain uninfected. The fraction of uninfected walkers is investigated numerically and found to decay algebraically, U(t) \sim t^{-ϕ(q)}, with a nontrivial exponent ϕ(q). Our study is extended to include the coupled diffusion-limited reaction A+A -> B, B+B -> A in one dimension with equal initial densities of A and B particles. We find that the density of walkers decays in this model as ρ(t) \sim t^{-1/2}. The fraction of sites unvisited by either an A or a B particle is found to obey a power law, P(t) \sim t^{-θ} with θ\simeq 1.33. We discuss these exponents within the context of the q-state Potts model and present numerical evidence that the fraction of walkers which remain uninfected decays as U(t) \sim t^{-ϕ}, where ϕ\simeq 1.13 when infection occurs between like particles only, and ϕ\simeq 1.93 when we also include cross-species contamination.

description: A sink-free orientation of a finite undirected graph is a choice of orientation for each edge such that every vertex has out-degree at least 1. Bubley and Dyer (1997) use Markov Chain Monte Carlo to sample approximately from the uniform distribution on sink-free orientations in time O(m^3 log (1/epsilon)), where m is the number of edges and epsilon the degree of approximation. Huber (1998) uses coupling from the past to obtain an exact sample in time O(m^4). We present a simple randomized algorithm inspired by Wilson's cycle popping method which obtains an exact sample in mean time at most O(nm), where n is the number of vertices.
