description: We present a higher dimensional, scale-invariant version of a classical theorem of F. and M. Riesz. More precisely, we establish scale invariant absolute continuity of harmonic measure with respect to surface measure, along with higher integrability of the Poisson kernel, for a domain $Ω\subset \mathbb{R}^{n+1},\, n\geq 2$, with a uniformly rectifiable boundary, which satisfies the Harnack Chain condition plus an interior (but not exterior) corkscrew condition. In a companion paper to this one [HMU], we also establish a converse, in which we deduce uniform rectifiability of the boundary, assuming scale invariant $L^q$ bounds, with $q>1$, on the Poisson kernel.
Sexuality education within high school curriculum in Uganda : exploring teachers’ perceptions of contextual influences on classroom discourses
Creators: name: Tushabomwe, Annette
Publisher: name: University of British Columbia
Year: 2014

description: This case study investigated teachers’ perceptions of contextual influences on their instruction and student engagement on sexuality discourses within four selected schools in Kampala, Uganda. The question that guided the study was: What and how are the contextual factors as perceived by health education teachers in Uganda influencing classroom discourses on sexuality? The research is grounded within two relevant theoretical frameworks; constructivism and the conceptual change theory (CCT). Constructivism acknowledges that individuals have preconceived notions rooted in their social, cultural and historical backgrounds, and CCT enables teachers to develop strategies that allow learners opportunities to reexamine their preconceptions about phenomena with a view of aligning them with canonical science. Through a narrative methodological approach, teachers narrated their stories based on their lived classroom experiences. Data sources included researcher’s field notes, e-mail correspondences, semi-structured questionnaires, and audio recordings of the teachers’ narratives. The data corpus was analyzed following intense dialogic analysis procedures, which encompassed elements of thematic and structural analytical methods as well as other broad interpretive dimensions such as how talk among speakers is dialogically produced. The findings revealed that while there is some form of sexuality education in schools and while teachers are very enthusiastic about its implementation, it is largely constrained by a plethora of contextual factors. Four themes that best addressed the inquiry were identified: 1) Dilemmas around navigating conflicting social stances; 2) Competing dichotomies with regards to adolescent sex health provision; 3) Teachers’ inadequate training to play the envisioned roles as sexuality educators; and 4) Relegation of Sex Health Education (SHE) to extracurricular status undermines its value and potential. The teachers therefore have a steep task to continue searching for appropriate pedagogical approaches to diffuse these dilemmas. This thesis provides a nuanced approach to understanding the practical realities and complexities involved in designing a framework for SHE delivery in schools, and also suggests various approaches teachers can employ to bring about meaningful learning.

Diagnosis.
Diagnostic characters are given under the newly described species. The male adult and genitalia are illustrated in Sato (2022), but we depict them here again for comparison with the other two species of difoveata - group. The female is still unknown at present.
Distribution.
Vietnam.
Genetic data.
No data available.
Remarks.
Stüning (2000: 135) already mentioned this species as “ an undescribed species also from Vietnam ”, which was later described as fansipana by Sato (2022: 226). He wrote in the description: “ Third abdominal sternite with setal comb ” and “ Hind tibia with hair-pencil ”. These two characters were mentioned by an unexplainable error (Sato 2023, pers. comm.). Both setal comb and hair-pencil are absent in all species of the genus Calcyopa, which, of course, was known to Sato.

description: The outcome of three-dimensional (3D) bioprinting heavily depends, amongst others, on the interaction between the developed bioink, the printing process, and the printing equipment. However, if this interplay is ensured, bioprinting promises unmatched possibilities in the health care area. To pave the way for comparing newly developed biomaterials, clinical studies, and medical applications (i.e. printed organs, patient-specific tissues), there is a great need for standardization of manufacturing methods in order to enable technology transfers. Despite the importance of such standardization, there is currently a tremendous lack of empirical data that examines the reproducibility and robustness of production in more than one location at a time. In this work, we present data derived from a round robin test for extrusion-based 3D printing performance comprising 12 different academic laboratories throughout Germany and analyze the respective prints using automated image analysis (IA) in three independent academic groups. The fabrication of objects from polymer solutions was standardized as much as currently possible to allow studying the comparability of results from different laboratories. This study has led to the conclusion that current standardization conditions still leave room for the intervention of operators due to missing automation of the equipment. This affects significantly the reproducibility and comparability of bioprinting experiments in multiple laboratories. Nevertheless, automated IA proved to be a suitable methodology for quality assurance as three independently developed workflows achieved similar results. Moreover, the extracted data describing geometric features showed how the function of printers affects the quality of the printed object. A significant step toward standardization of the process was made as an infrastructure for distribution of material and methods, as well as for data transfer and storage was successfully established.

These Specht modules are labelled by partitions of the form $(a,3,1^b)$, and are the first new examples found for thirty years. Our method of proof is to exhibit summands isomorphic to irreducible Specht modules, by constructing explicit homomorphisms between Specht modules.

description: We describe a scalable experimental protocol for obtaining estimates of the error rate of individual quantum computational gates. This protocol, in which random Clifford gates are interleaved between a gate of interest, provides a bounded estimate of the average error of the gate under test so long as the average variation of the noise affecting the full set of Clifford gates is small. This technique takes into account both state preparation and measurement errors and is scalable in the number of qubits. We apply this protocol to a superconducting qubit system and find gate errors that compare favorably with the gate errors extracted via quantum process tomography.

description: Poly(ethylene glycol) (PEG) based networks have been used extensively for biomedical applications and as solid state electrolytes. In this work, a series of PEG networks was prepared using bifunctional PEG of molar mass 400, 1000, 2000, 4000, and 6000 g mol−1 and star shaped PEG (Mn = 1000 g mol−1) cross-linker using copper-catalyzed Huisgen 1,3-dipolar cycloaddition or “click” chemistry. The end-group modification of the bifunctional polymers and the star shaped cross-linker with alkyne and azide groups, respectively, was confirmed by 1H NMR spectroscopy. The coupling reaction between azide and alkyne functionalities for the network formation was confirmed by Fourier transform infrared (FTIR) spectroscopy. The thermal properties of polymer network were determined by differential scanning calorimetry. Swelling studies of the networks were performed to correlate the network structure with the physical properties. The molar mass between the cross-links was determined using the Bray-Merill modified Flory-Rehner equation. The effect of molar mass between the cross-linking points on the strength of the networks was compared. Additionally, the effect of the stoichiometry of the precursors on the network strength was also studied. Finally, thickness-dependent tensile testing was performed to investigate the stress oscillation phenomenon.
What is user engagement? An interdisciplinary perspective on users' interaction with ‎information technology
Creators: name: Dvir, Nim
Publisher: name: Zenodo
Year: 2019
Subjects: ux

description: In recent years, the term user engagement (UE) has been increasingly used to describe users’ interactions with Information and communication technologies (ICT). Given the competition for users’ attention and interest, it is agreed that technologies must engage users to be successful. However, current research is unstructured and spread across various disciplines, leading ‎to wide-ranging, and sometimes disparate, perspectives, vocabularies, and measurement ‎methodologies‎. The purpose of this paper is to critically deconstruct the concept of user engagement to mitigate the discrepancies and improve current knowledge. Through an extensive, critical multidisciplinary literature review, we synthesize established theories and prior research to conceptually and operationally defined engagement. By bringing together interdisciplinary perspectives and insights, we also identify antecedents (determinants), attributes and outcomes of user engagement. The review concludes by proposing an agenda for future research in this area.

description: Der Sachunterricht beschäftigt sich mit Sachzusammenhängen. Seine grundsätzliche didaktische Zielsetzung besteht deshalb darin, mit Sachzusammenhängen umzugehen und nicht mit Bildern oder Texten über Sachen. Mit Sachen umgehen kann entweder heißen, sie in der Realität, also außerhalb der Schule aufzusuchen oder sie in die Schule hereinzuholen. Drei Gründe legen es dennoch nahe, auch Materialien im Sachunterricht einzusetzen: Es gibt Sachzusammenhänge, die nicht aufgesucht und untersucht werden können. Etwa: Einen Ameisenhaufen darf man nicht zerstören und eine Schulklasse kann man nicht bei einer Geburt zuschauen lassen. Materialien können die Auseinandersetzung mit Sachzusammenhängen vorbereiten oder begleiten. Es lassen sich aus Büchern und Bildern Anregungen entnehmen, ebenso Fragen oder Aufgaben. Die Dokumentation der Sachbegegnung kann ebenfalls durch Materialien unterstützt werden. Sachzusammenhänge sind komplex. Materialien können eine Reduktion der Komplexität vornehmen, indem sie das Wesentliche eines Zusammenhanges enthalten. Hier geht es vor allem um Dinge, um Geräte oder einfache Abläufe. Diese Gegenstände können - im Unterschied zur Realität - Kindern die Möglichkeit bieten, selbst handelnd mit ihnen umzugehen. Diese Ausgangsthesen beinhalten eine bestimmte Grundposition zum Sachunterricht. Die Diskussion der Materialien zum Sachunterricht kann nicht von der Didaktik des Sachunterrichts getrennt werden, denn die Art des Zuganges zu einem Sachverhalt ist entscheidend dafür, was eigentlich von der Sache gelernt wird.

description: We calculate Bayes factors to quantify how the feasibility of the constrained minimal supersymmetric standard model (CMSSM) has changed in the light of a series of observations. This is done in the Bayesian spirit where probability reflects a degree of belief in a proposition and Bayes' theorem tells us how to update it after acquiring new information. Our experimental baseline is the approximate knowledge that was available before LEP, and our comparison model is the Standard Model with a simple dark matter candidate. To quantify the amount by which experiments have altered our relative belief in the CMSSM since the baseline data we compute the Bayes factors that arise from learning in sequence the LEP Higgs constraints, the XENON100 dark matter constraints, the 2011 LHC supersymmetry search results, and the early 2012 LHC Higgs search results. We find that LEP and the LHC strongly shatter our trust in the CMSSM (with $M_0$ and $M_{1/2}$ below 2 TeV), reducing its posterior odds by a factor of approximately two orders of magnitude. This reduction is largely due to substantial Occam factors induced by the LEP and LHC Higgs searches.

description: In der gegenwärtigen Medizinethik gilt die Autonomie der Patient:innen als das normative Kriterium für alle Entscheidungen im medizinischen Kontext. Hierdurch wurde das Prinzip der paternalistischen Fürsorge abgelöst. Die vorliegende Arbeit zeigt auf, wie Menschen im Allge-meinen sowie in ihrer Rolle als Patient:innen Entscheidungen treffen. Dabei wird dargelegt welche Faktoren auf die individuelle Entscheidungsfindung Einfluss nehmen und was dies für die Beziehung zwischen Ärzt:innen und Patient:innen im klinischen Alltag bedeutet. Die vor-liegende Arbeit widmet sich dieser Thematik interdisziplinär, in dem sie neben philosophi-schen, geisteswissenschaftlichen Argumentationen auch Erkenntnisse aus der naturwissen-schaftlichen Forschung mit einbezieht. Ziel war es die Strukturen der individuellen Willens- und Entscheidungsfindung sowie der persönlichen Autonomiefähigkeit aufzuzeigen, um menschliches Denken und Handeln im Allgemeinen sowie im klinischen Kontext besser zu ver-stehen.
description: In current medical ethics, patient autonomy is considered the normative criterion for all deci-sions in a medical context. This replaced the principle of paternalistic care. This dissertation shows how people make decisions in general and in their role as patients. It shows which fac-tors influence individual decision-making and what this means for the relationship between physicians and patients in everyday clinical practice. The present work addresses this topic in an interdisciplinary way, incorporating philosophical, humanistic argumentation as well as fin-dings from scientific research. The aim of this work was to demonstrate the structures of in-dividual will- and decision-making as well as personal autonomy in order to better understand human thinking and acting in general and in the clinical context.

description: Dual Lukacs type characterizations of random variables in free probability are studied here. First, we develop a freeness property satisfied by Lukacs type transformations of free-Poisson and free-Binomial non-commutative variables which are free. Second, we give a characterization of non-commutative free-Poisson and free-Binomial variables by properties of first two conditional moments, which mimic Lukacs type assumptions known from classical probability. More precisely, our result is a non-commutative version of the following result known in classical probability: if $U$, $V$ are independent real random variables, such that $E(V(1-U)|UV)$ and $E(V^2(1-U)^2|UV)$ are non-random then $V$ has a gamma distribution and $U$ has a beta distribution.

description: Modern wearable monitors and laboratory equipment allow the recording of high-frequency data that can be used to quantify human movement. However, currently, data analysis approaches in these domains remain limited. This paper proposes a new framework to analyze biomechanical patterns in sport training data recorded across multiple training sessions using multilevel functional models. We apply the methods to subsecond-level data of knee location trajectories collected in 19 recreational runners during a medium-intensity continuous run (MICR) and a high-intensity interval training (HIIT) session, with multiple steps recorded in each participant-session. We estimate functional intra-class correlation coefficient to evaluate the reliability of recorded measurements across multiple sessions of the same training type. Furthermore, we obtained a vectorial representation of the three hierarchical levels of the data and visualize them in a low-dimensional space. Finally, we quantified the differences between genders and between two training types using functional multilevel regression models that incorporate covariate information. We provide an overview of the relevant methods and make both data and the R code for all analyses freely available online on GitHub. Thus, this work can serve as a helpful reference for practitioners and guide for a broader audience of researchers interested in modeling repeated functional measures at different resolution levels in the context of biomechanics and sports science applications.

description: Es wurde ein transgenes Mausmodell (TG) mit Herz-spezifischer Überexpression des menschlichen Histamin-H2-Rezeptors charakterisiert. Als Kontrolle dienten Wildtyp-Mäuse (WT) ohne funktionellen H2-Rezeptor. Es wurden isolierte linke und spontan kontrahierende rechte Vorhofpräparate (VH) untersucht sowie echokardiographische Untersuchungen durchgeführt. Die TG-VH zeigten basal eine erhöhte Kontraktionskraft und Schlagfrequenz. H2-Rezeptor-Agonisten (Histamin oder Dimaprit) führten bei TG zu positiv inotropen und chronotropen Effekten, die durch den H2-Rezeptor-Antagonisten Cimetidin unterdrückt wurden. Bei rechten TG-VH induzierten H2-Agonisten Arrhythmien, die Cimetidin-sensitiv waren. In Ultraschalluntersuchungen hatten TG-Tiere basal eine erhöhte Ejektionsfraktion (EF) und Herzfrequenz (HF); Histamin bedingte bei TG einen Anstieg der EF und HF. Zusammengefasst: Histamin und Dimaprit wirkten über H2-Rezeptoren positiv inotrop, chronotrop und proarrhythmogen; Cimetidin hemmte diese Effekte und wirkte somit antiarrhythmisch. Eine Übertragbarkeit auf den Menschen muss in zukünftigen Arbeiten untersucht werden.
description: A transgenic mouse model (TG) with cardiac specific overexpression of the human histamine H 2 receptor was characterized. Wild type (WT) mice lacking functional H 2 receptor served as controls. Isolated left and spontaneously contracting right atrial preparations (AP) were examined, and echocardiographic studies were performed. TG AP basally showed an increased contractile force and heartbeat frequency. H 2 receptor agonists (histamine or dimaprit) induced positive inotropic and chronotropic effects in the TG that the H 2 receptor antagonist cimetidine suppresse d. In right TG AP, H 2 agonists induced arrhythmias that were cimetidine sensitive. In ultrasound studies, TG animals had a basally increased ejection fraction (EF) and heart rate (H R ); histamine caused an increase in EF and H R in TG. In summary, histamine and dimaprit acted positively inotropic, chronotropic, and proarrhythmogenic via H 2 receptors; cimetidine inhibited these effects and thus acted antiarrhythmically. Transferability to humans needs to be investigated in future work.

description: As ecometabolomics gains more and more interest, not just as a tool to investigate the metabolomic adaptations but also to bring them in context with the plant community level, the need for tailored and structured methods that effectively combine both the vast amount of metabolomics data and the natural diversity in ecological data increases rapidly. Using the secondary metabolite profiles in thirteen grassland plant species and their response to a changing neighbourhood regarding plant species richness and diversity caused by different seasons as an example setup, this thesis focused on providing a road map for integrating metabolomics data to complex ecological environments and implementing reproducible, standardised methods across multiple experimental setups as well as on adapting existing methods to the need of ecometabolomics data sets. Unravelling specific mechanisms reflected in the metabolic profiles will provide insights into underlying ecosystem functions.

Anhand von Sekundärmetabolit-Profilen in dreizehn Grasland Pflanzenarten und ihrer chemischen Antwort auf eine sich ändernde Pflanzengemeinschaft, konzentrierte sich diese Dissertation darauf, eine Roadmap für die Integration von Metabolomdaten in komplexe Umgebungen bereitzustellen und reproduzierbare, standardisierte Methoden über mehrere experimentelle Setups hinweg zu implementieren, sowie bestehende Methoden an die Bedürfnisse von Ecometabolomics-Datensätzen anzupassen. Die Entschlüsselung spezifischer Mechanismen, die sich in den metabolischen Profilen widerspiegeln, wird Einblicke in zugrunde liegende Ökosystemfunktionen liefern.

description: We prove the global triangulation conjecture for families of refined p-adic representations under a mild condition. That is, for a refined family, the associated family of (phi, Gamma)-modules admits a global triangulation on a Zariski open and dense subspace of the base that contains all regular non-critical points. We also determine a large class of points which belongs to the locus of global triangulation. Furthermore, we prove that all the specializations of a refined family are trianguline. In the case of the Coleman-Mazur eigencurve, our results provide the key ingredient for showing its properness in a subsequent work.

It is proven by comparing chromatograms of blank, Placebo and sample preparation solution; there was no interference of excipients with the peak of FIK and CLN.

description: With the launch of the optical Sentinel-2 and Synthetic Aperture Radar (SAR) Sentinel-1 satellites, the public got access to freely available data with a high spatial-temporal resolution, which has boosted great interest in the applicability of the optical-SAR combination for crop type mapping. This thesis examines the potential of the Sentinel-1 and Sentinel-2 data synergy for crop type mapping. The thesis consists of three major parts: 1) the systematic review of existing research publications; 2) the study on large-scale crop type mapping using bi-weekly time-series features from both sensors to map 16 crop classes in Brandenburg (Germany); 3) examining and improving the spatial transferability of Random Forest models for crop type mapping across Germany. The research outcomes of the thesis present the advantages and limitations of using one or the combination of both, Sentinel-1 and Sentinel-2 data sources for large-scale, detailed crop type mapping in Germany.
description: Mit dem Start der optischen Sentinel-2- und SAR (Synthetic Aperture Radar) Sentinel-1-Satelliten erhielt die Öffentlichkeit Zugang zu frei verfügbaren Daten mit einer hohen räumlichen und zeitlichen Auflösung, was zu einem großen Interesse an der Anwendbarkeit der Kombination von optischen und SAR-Daten für die Kartierung von landwirtschafltichen Kulturarten führte. In dieser Arbeit wird das Potenzial der Synergie von Sentinel-1- und Sentinel-2-Daten für die Kartierung von Kulturpflanzen untersucht. Die Arbeit besteht aus drei Hauptteilen: 1) die systematische Durchsicht bestehender Forschungspublikationen; 2) die Studie zur großflächigen Kartierung von Kulturpflanzen unter Verwendung zweiwöchentlicher Zeitreihenmerkmale beider Sensoren zur Kartierung von 16 Kulturpflanzenklassen in Brandenburg (Deutschland); 3) die Untersuchung und Verbesserung der räumlichen Übertragbarkeit von Random Forest Modellen für die Kartierung von Kulturpflanzen in ganz Deutschland.

description: We study low-lying states of even carbon isotopes in the range A = 10 - 20 within the large- scale no-core shell model (NCSM). Using several accurate nucleon-nucleon (NN) as well as NN plus three-nucleon (NNN) interactions, we calculate excitation energies of the lowest 2+ state, the electromagnetic B(E2; 2+1 -> 0+1) transition rates, the 2+1 quadrupole moments as well as se- lected electromagnetic transitions among other states. Recent experimental campaigns to measure 2+-state lifetimes indicate an interesting evolution of nuclear structure that pose a challenge to reproduce theoretically from first principles. Our calculations do not include any effective charges or other fitting parameters. However, calculated results extrapolated to infinite model spaces are also presented. The model-dependence of those results is discussed. Overall, we find a good agree- ment with the experimentally observed trends, although our extrapolated B(E2; 2+1 -> 0+1) value for 16C is lower compared to the most recent measurements. Relative transition strengths from higher excited states are investigated and the influence of NNN forces is discussed. In particular for 16C we find a remarkable sensitivity of the transition rates from higher excited states to the details of the nuclear interactions.

description: Das Fahrrad, der menschliche Körper, die Uhr und das Thermometer gelangen auf eigentümliche Weise in die Schule und in den Klassenraum. Sie werden an diesem Ort jeweils zu einer schulischen Lernaufgabe gemacht. Im Folgendem möchte ich die Frage ins Zentrum rücken, wie die Sachen – seien es natürliche, technische oder soziale – zu einer schulischen Lernaufgabe werden. Dazu werde ich zunächst schulpädagogische Perspektiven auf die Didaktik des Sachunterrichts explizieren, um dann meinen empirischen Zugang zu Unterricht und schulischem Lernen zu konkretisieren. Im Anschluss daran werde ich meine Schlußfolgerungen für den integrativen Sachunterricht erläutern.

The design and application of an agricultural sustainability index using item response theory

description: Agricultural sustainability (AS) is a key component in the UN's Sustainable Development Goals. Despite wide use of the concept in both research and policy, there is still not a universally accepted method for its measurement. This research proposes using item response theory (IRT) to generate a farm-level AS index. The thesis is comprised of three scientific articles: The first article develops and tests the IRT model design, second applies the model to the sustainability of non-food crop production in the context of the bioeconomy, and the third looks into the sustainability of organic versus conventional farms. The key findings of the research are that (1) constructing an AS index with IRT may be a suitable alternative to existing methods, (2) farms producing a combination of non-food crops with food crops are more sustainable on average than those not producing non-food crops, and (3) organic farms are more sustainable on average than conventional farms.
description: Landwirtschaftliche Nachhaltigkeit (agricultural sustainability; AS) ist eine Schlüsselkomponente der UN-Ziele für nachhaltige Entwicklung. Obwohl das Konzept sowohl in der Forschung als auch in der Politik weit verbreitet ist, gibt es noch immer keine allgemein anerkannte Methode zu seiner Messung. In dieser Forschungsarbeit wird vorgeschlagen, die Item-Response-Theorie (IRT) anzuwenden, um einen AS-Index auf Betriebsebene zu erstellen. Die Arbeit besteht aus drei wissenschaftlichen Artikeln: Der erste Artikel entwickelt und testet das Design des IRT-Modells, der zweite wendet das Modell auf die Nachhaltigkeit der Non-Food-Pflanzenproduktion im Kontext der Bioökonomie an, und der dritte untersucht die Nachhaltigkeit von ökologischen gegenüber konventionellen Betrieben. Die wichtigsten Ergebnisse der Forschung sind, dass (1) die Konstruktion eines AS-Indexes mit dem IRT eine geeignete Alternative zu bestehenden Methoden sein kann, (2) Betriebe, die eine Kombination von Nichtlebensmittelpflanzen mit Nahrungspflanzen produzieren, im Durchschnitt nachhaltiger sind als solche, die keine Nichtlebensmittelpflanzen produzieren, und (3) ökologische Betriebe im Durchschnitt nachhaltiger sind als konventionelle Betriebe.
Borders within the border : economic development and mobility in two sub-regions of the Pearl River delta, South China

description: This dissertation explores how local labour markets and labour migration are constructed within in the Pearl River delta region in Guangdong province, south China. The Pearl River delta region has become one of the most industrialized and prosperous regions in China since economic reform began in 1979. Industrial growth has occurred in areas that were primarily agricultural, yet the trajectory of growth has been uneven. Uneven development has generated two distinct economic structures and economic activities within the delta region. The core area is highly industrialized, and partially urbanized, while the periphery is less industrialized and by Pearl River delta standards marginally developed. The data for this study were derived primarily from a survey conducted in five formerly rural communities in the Pearl River delta. Over 400 labour migrants were interviewed. Ethnographic observation and secondary documentary analysis complemented the survey data. I argue, firstly, that rural industrialization created large scale labour migration in and around village settlements rather than urban areas. Labour market formation in Chinese rural contexts offers a sharp contrast to current migration studies and labour market formation. Secondly, the hukou system and other policies of residence management have major consequences for labour migration in China. Labour migration occurs in a domestic context and despite some distinctions occurs within a single cultural system. Chinese labour migrants cross administrative boundaries and face cultural adjustment such as language and industrial work. They can be seen as analogous to foreign workers as described in international migration studies. Yet institutional arrangements create unequal access to the benefits of citizenship and distinctive living arrangements. They generate contested identities in the places where migrants seek employment. The social networks of migrants have become facilitating factors in obtaining jobs and initial settlement, yet they may also hinder social integration into highly solidary host communities. This study has implications beyond labour market formation and identity change. Given the large population of labour migrants in China and the patterns of labour migration under specific institutional context and local social characteristics, it casts light on the profound social transformation in China as a whole.
