Formalising informal finance in Henan, China
Creators: name: Wang, C
Publisher: name: CQUniversity
Year: 2017
Subjects: classificationCode: 350203
subject: Financial econometrics

description: "The goal of this thesis is to identify a set of regulatory strategies which potentially enhance the effectiveness of government regulation on Henan’s informal financial sector, so that the role of informal financial sector can be formalised: the positive economic functions could be enhanced and problematic aspects of the financial activities could be mitigated, which allowing the informal financial sector to transform into a more formal, accountable and acceptable financing channel for the residents. To provide a solid platform for the study, various theoretical studies are examined allowing for knowledge on informal finance in Henan, including the definition, the background information and the scale of informal financial sector. To put the need for formalising informal finance in Henan, this thesis also examines different perspectives of informal financial regulation both in Henan and worldwide. A regulatory framework is provided based on analyses of these theoretical studies. In order to fill the gap between theriacal solutions and actual practices in the context of Henan, it is essential to gather field data regarding Henan’s informal finance and its regulation. The scope of the field research is thus covers an online questionnaire survey of 224 Henan’s residents to gain a general picture of Henan’s informal financial sector through seeking their opinions and aspirations. The data generated from the online survey are then triangulated with the considered views of 20 field workers in Henan. The views of the 20 field workers, including the managers of informal financial institutions, the government officials and the financial experts are solicited through in-depth interviews. The key findings that emerged out of the field data analysis is that Henan’s informal financial sector could be potentially formalised through seven strategies, including expansion of private investment channels and promotion of interest rate liberalisation, reinforcement of government control and legislation over informal finance, reformation of credit culture, establishment of a sound credit history system and integration of formal and informal financial institutions. A set of regulatory recommendations based on the key findings is also provided. It is expected that these recommendations, if implemented, would allow Henan’s informal financial sector to gain higher transparency and reliability, eventually become an alternative financing channel for Henan’s residents."--Abstract.

description: In the recently introduced Variable-Shape heaving wave energy converters, the buoy changes its shape actively in response to changing incident waves. In this study, a Lagrangian approach for the dynamic modeling of a spherical Variable-Shape Wave Energy Converter is described. The classical bending theory is used to write the stress-strain equations for the flexible body using Love's approximation. The elastic spherical shell is assumed to have an axisymmetric vibrational behavior. The Rayleigh-Ritz discretization method is adopted to find an approximate solution for the vibration model of the spherical shell. A novel equation of motion is presented that serves as a substitute for Cummins equation for flexible buoys. Also, novel hydrodynamic coefficients that account for the buoy mode shapes are proposed. The developed dynamic model is coupled with the open-source boundary element method software NEMOH. Two-way and one-way Fluid-Structure Interaction simulations are performed using MATLAB to study the effect of using a flexible shape buoy in the wave energy converter on its trajectory and power production. Finally, the variable shape buoy was able to harvest more energy for all the tested wave conditions.

Developmentally appropriate programming in a primary school: A case study
Creators: name: Richardson, Paul
Publisher: name: CQUniversity
Year: 2017
Subjects: classificationCode: 390304
subject: Primary education

description: Much of the dialogue amongst educators about contemporary schooling focuses on the achievement of student learning outcomes. The literature indicates that there have been ongoing calls for change to traditional schooling constructs. Traditional schooling models provide programs of instruction formed on the basis of student ages with school curricula being designed for and delivered to students using grade level programs. However, it is well documented that a child's rate of personal development may not be aligned to the chronologically determined traditional schooling construct. This research concerns the use of Developmentally Appropriate Programming (DAP) in a primary school. It has been framed in the context whereby learning groups, which group learners according to the emotional and mental development, are used. The case study explores and describes the evolution and ongoing practices of DAP at this school using the views, opinions and perceptions of the staff, parents and students of the school who had been involved in DAP as well as documentation available at the school. The results of the research reveal that the use of DAP was implemented to more appropriately cater for the educational needs and requirements of the learner. Both the staff and the parents involved in this case study perceived that the way that DAP operated differed to traditional schools with respect to the use of more flexibility in learning programs, the placing of students in learning groups, role of teachers and the structures of the learning groups. The students themselves perceived that being part of a learning group allowed them to do well and achieve improved learning outcomes. The results from this case study can be used by educators to inform them on the use of DAP.

description: Generalization is an important attribute of machine learning models, particularly for those that are to be deployed in a medical context, where unreliable predictions can have real world consequences. While the failure of models to generalize across datasets is typically attributed to a mismatch in the data distributions, performance gaps are often a consequence of biases in the 'ground-truth' label annotations. This is particularly important in the context of medical image segmentation of pathological structures (e.g. lesions), where the annotation process is much more subjective, and affected by a number underlying factors, including the annotation protocol, rater education/experience, and clinical aims, among others. In this paper, we show that modeling annotation biases, rather than ignoring them, poses a promising way of accounting for differences in annotation style across datasets. To this end, we propose a generalized conditioning framework to (1) learn and account for different annotation styles across multiple datasets using a single model, (2) identify similar annotation styles across different datasets in order to permit their effective aggregation, and (3) fine-tune a fully trained model to a new annotation style with just a few samples. Next, we present an image-conditioning approach to model annotation styles that correlate with specific image features, potentially enabling detection biases to be more easily identified.

description: Social media may create echo chambers that reaffirm users' beliefs and opinions through repeated exposure of similar notions. Whilst the formation and effect of echo chambers have been intensively examined in thread-based platforms such as Twitter, Facebook and Reddit, we shift our focus on product review discussions on YouTube. This paper examines YouTube comments (n=2500) through a combined approach of quantitative content analysis (QCA) and sentiment analysis (SA) under selected selected YouTube videos (n=10). We conclude this paper by highlighting the formation of echo chamber effect in relation to comment argumentation and sentiments.

description: The purpose of this article is to observe that the zero sets of continuous-state branching processes with immigration (CBI) are infinitely divisible regenerative sets. Indeed, they can be constructed by the procedure of random cutouts introduced by Mandelbrot in 1972. We then show how very precise information about the zero sets of CBI can be obtained in terms of the branching and immigrating mechanism.

description: We study electronic properties of a superconducting topological insulator whose parent material is a topological insulator. We calculate the temperature dependence of the specific heat and spin susceptibility for four promising superconducting pairings proposed by L. Fu and E. Berg (Phys. Rev. Lett. 105, 097001). Since the line shapes of temperature dependence of specific heat are almost identical among three of the four pairings, it is difficult to identify them simply from the specific heat. On the other hand, we obtain wide varieties of the temperature dependence of spin susceptibility for each pairing reflecting the spin structure of Cooper pair. We propose that the pairing symmetry of superconducting topological insulator can be determined from measurement of Knight shift by changing the direction of applied magnetic field.

Using two well defined dimensionless system parameters, universal characteristics of the optimal heat current condition are identified. It is shown to be independent of any system parameter and is obtained only at the mean transitions point "$-0.5$", associated with the equilibrium distribution of the two fermionic reservoirs, tacitly referred to as "$\textit{universal magic mean}$".

description: Student progression is historically dominated by indicators of academic success, denoted by passing subjects and successfully completing qualifications. More recently this university management view of progression has been linked to institutional audit measures with these providing secondary data archives for research into progression. This thesis provides a student perspective on progression. To do so it necessarily encompasses wider student goals and aspirations that extend beyond the university to include career and professional growth. The research uses a sequential mixed methods approach with three main studies (archive, survey and interview) each aligned with a research objective. The first study in the series is an archive study of 1547 university Built Environment student records that were originally collected as part of the requirement for the university to report its work for government audit. The second study was a self-report structured online survey that collected data from a total of 295 students. The student sample was made up of 154 Built Environment students and 141 Engineering students. 97, all Built Environment students, were distance education students and the other 198 students were campus-based students. The final study, the in-depth interview study, used one-on-one interactive conversational interviews with students, graduates, academics, employers and executives from professional organisations. In total 40 interviews were undertaken. A number of influences were found on progression as seen from a student perspective. These include the importance of work-readiness, cadetships and the alignment of qualifications with industry needs and career growth opportunities. The student user perspective also brought into focus a number of the pedagogical assumptions held about and held by students in the Built Environment.

description: The short GRB 120323A had the highest flux ever detected with the Fermi/GBM. Here we study its remarkable spectral properties and their evolution using two spectral models: (i) a single emission component scenario, where the spectrum is modeled by the empirical Band function, and (ii) a two component scenario, where thermal (Planck-like) emission is observed simultaneously with a non-thermal component (a Band function). We find that the latter model fits the integrated burst spectrum significantly better than the former, and that their respective spectral parameters are dramatically different: when fit with a Band function only, the Epeak of the event is unusually soft for a short GRB, while adding a thermal component leads to more typical short GRB values. Our time-resolved spectral analysis produces similar results. We argue here that the two-component model is the preferred interpretation for GRB 120323A, based on: (i) the values and evolution of the Band function parameters of the two component scenario, which are more typical for a short GRB, and (ii) the appearance in the data of a significant hardness-intensity correlation, commonly found in GRBs, when we employee two-component model fits; the correlation is non-existent in the Band-only fits. GRB 110721A, a long burst with an intense photospheric emission, exhibits the exact same behavior. We conclude that GRB 120323A has a strong photospheric emission contribution, first time observed in a short GRB. Magnetic dissipation models are difficult to reconcile with these results, which instead favor photospheric thermal emission and fast cooling synchrotron radiation from internal shocks. Finally, we derive a possibly universal hardness-luminosity relation in the source frame using a larger set of GRBs L,i=(1.59+/-0.84).10^50 (Epeak,i)^(1.33+/-0.07) erg/s), which could be used as a possible redshift estimator for cosmology.

description: Gas giant planets orbiting within 0.1 AU of their host stars, unlikely to have formed in situ, are evidence for planetary migration. It is debated whether the typical hot Jupiter smoothly migrated inward from its formation location through the proto-planetary disk or was perturbed by another body onto a highly eccentric orbit, which tidal dissipation subsequently shrank and circularized during close stellar passages. Socrates and collaborators predicted that the latter class of model should produce a population of super-eccentric proto-hot Jupiters readily observable by Kepler. We find a paucity of such planets in the Kepler sample, inconsistent with the theoretical prediction with 96.9% confidence. Observational effects are unlikely to explain this discrepancy. We find that the fraction of hot Jupiters with orbital period P > 3 days produced by the star-planet Kozai mechanism does not exceed (at two-sigma) 44%. Our results may indicate that disk migration is the dominant channel for producing hot Jupiters with P > 3 days. Alternatively, the typical hot Jupiter may have been perturbed to a high eccentricity by interactions with a planetary rather than stellar companion and began tidal circularization much interior to 1 AU after multiple scatterings. A final alternative is that tidal circularization occurs much more rapidly early in the tidal circularization process at high eccentricities than later in the process at low eccentricities, contrary to current tidal theories.
description: Accepted to ApJ on October 20, 2014. We adopted more conservative assumptions about completeness and waited for a candidate sample based on double the number of Kepler quarters. With the updated sample and assumptions, the conclusions remain the same

description: We simplify and extend our previous model for the masses and mixing matrix of three Majorana neutrinos based on permutation symmetry $S_3$ and the perturbations which violate this symmetry. The perturbations are arranged such that we get the smaller solar neutrinos mass difference at second order. We work out the corrections to the tribimaximal mixing matrix with the non-zero value for $s_{13}$ and the conventional CP-violating phase. It is shown that the results of the model are comparable with the global analysis of neutrino oscillation data.

description: The spread of rumors, which are known as unverified statements of uncertain origin, may cause tremendous number of social problems. If it would be possible to identify factors affecting spreading a rumor (such as agents' desires, trust network, etc.), then this could be used to slowdown or stop its spreading. A computational model that includes rumor features and the way a rumor is spread among society's members, based on their desires, is therefore needed. Our research is centering on the relation between the homogeneity of the society and rumor convergence in it and result shows that the homogeneity of the society is a necessary condition for convergence of the spreading rumor.

description: The understanding of friction at nano-scales, ruled by the regular arrangement of atoms, is surprisingly incomplete. Here we provide a unified understanding by studying the interlocking potential energy of two infinite contacting surfaces with arbitrary lattice symmetries, and extending it to finite contacts. We categorize, based purely on geometrical features, all possible contacts into three different types: a structurally lubric contact where the monolayer can move isotropically without friction, a corrugated and strongly interlocked contact, and a newly discovered directionally structurally lubric contact where the layer can move frictionlessly along one specific direction and retains finite friction along all other directions. This novel category is energetically stable against rotational perturbations and provides extreme friction anisotropy. The finite-size analysis shows that our categorization applies to a wide range of technologically relevant materials in contact, from adsorbates on crystal surfaces to layered two-dimensional materials and colloidal monolayers.
A UPFC with reduced DC bus capacitance for voltage regulation and phase balancing in LV distribution networks with high PV penetrations

description: The penetration level of photovoltaic (PV) power in the low voltage (LV) distribution networks is rapidly increasing. The European Photovoltaic Industry Association reported the installed capacity of PV systems globally reached 177GW at the end of 2014. The annual rate of installations, 38.7GW in 2014, continues to increase. A large part of this is installed as residential systems connected to LV networks. The Australian Clean Energy Regulator has published a report showing the total installed capacity of PV in Australia exceeded 4.5GW in 2015. The impacts of high PV penetrations in LV residential distribution networks include voltage rise, voltage unbalance, and reverse power flow which may limit the level of photovoltaic penetration within the LV distribution networks. A four-leg compensator based on a unified power flow controller (UPFC) concept is proposed for simultaneous voltage and current compensation in LV distribution systems. As a voltage compensator, this compensation device is shown to be capable of regulating the positive, negative and zero sequence voltage in LV distribution networks under high PV penetrations. At the same time, as a current compensator, the device is capable of power factor correction, zero sequence or neutral current compensation, harmonic current compensation and a degree of negative sequence current compensation. Instantaneous reactive power theory shows that DC-bus capacitor power will fluctuate at twice mains frequency during any unbalanced operation of the regulator. Real and instantaneous power balance of the UPFC can be maintained by allowing the input shunt converter to draw a small positive and negative sequence current respectively. Instantaneous power balance with negative sequence current makes it possible to reduce the DC bus capacitance which allows long life ceramic or polypropylene capacitors to replace electrolytic capacitors. The operation of the proposed UPFC based four-leg compensator has been demonstrated by extensive simulation studies. These confirm that the device can perform the full range of series and parallel compensation duties for the compensation of voltage and current respectively. It has also been demonstrated that the DC bus voltage can be controlled using relatively small DC bus capacitors. The simulation work is further confirmed by experimental work with a small scale laboratory model. The laboratory system used commercial inverter modules rated at 600V and 15A per phase to construct two inverters with four phase legs. These were configured as a parallel connected inverter and a series inverter with series voltage injection transformers. The four-leg inverters shared a common DC bus and were equipped with voltage and current transformers and controlled using a Texas Instruments Delfino processor.

description: The present work is trying to explain a discrepancy between experimental observations of the drainage of foam films from aqueous solutions of sodium dodecyl sulfate (SDS) and the theoretical DLVO-accomplished Reynolds model. It is shown that, due to overlap of the film adsorption layers, an adsorption component of the disjoining pressure is important for this system. The pre-exponential factor of the adsorption component was obtained by fitting the experimental drainage curves. It corresponds to a slight repulsion, which reduces not only the thinning velocity as observed experimentally but corrects also the film equilibrium thickness.

description: We theoretically investigate the effect of inter-molecular Coulomb interactions on transport through molecular monolayers (or other devices based on a large number of nanoscale conductors connected in parallel). Due to the interactions, the current through different molecules become correlated, resulting in distinct features in the non-linear current-voltage characteristics, as we show by deriving and solving a type of modified master equation, suitable for describing transport through an infinite number of interacting conductors. Furthermore, if some of the molecules fail to bond to both electrodes, charge traps can be induced at high voltages and block transport through neighboring molecules, resulting in negative differential resistance.

description: A new astronomical observatory in southeastern Indonesia is currently under construction. This Timau National Observatory will host a 3.8-metre telescope for optical and near-infrared observations. To support the operation and planning, the characterisation of the site needs to be appropriately performed. However, limited resources and access to the site hindered the deployment of instruments for comprehensive site testing. Fortunately, \emph{in-situ} sky brightness data from the Sky Quality Meter (SQM) have been available for almost two years. Based on the data acquired in 470 nights, we obtain a background sky brightness of $μ_0=21.86\pm0.38$ magnitude/arcsec$^2$. Additionally, we evaluate the moonlit sky brightness to estimate the atmospheric extinction coefficient ($k$) and level of scattering on site. We find an alleviated value of $k=0.48\pm0.04$, associated with a high atmospheric aerosol content. It is considered regular for an equatorial area situated at a low altitude (${\sim}1300$ masl). By analysing the fluctuation of the sky brightness and infrared images from \emph{Himawari-8} satellite, we estimate the available observing time (AOT) of at least $5.3$ hours/night and the yearly average percentage of usable nights of $66\%$. The monthly average AOT from SQM and satellite data analysis correlate with $R=0.82$. In terms of the monthly percentage of usable nights, the correlation coefficient is $R=0.78$. During the wet season (November-April), the results from SQM and satellite data analysis deviate more significantly, mainly due to the limited capability of Himawari-8 in detecting fragmented low-altitude clouds. According to these results, we expect Timau to complement other observatories greatly.

Bounds on TeV Seesaw Models from LHC Higgs Data

description: We derive bounds on the Dirac Yukawa couplings of the neutrinos in seesaw models using the recent Large Hadron Collider (LHC) data on Higgs decays for the case where the Standard Model singlet heavy leptons needed for the seesaw mechanism have masses in the 100 GeV range. Such scenarios with large Yukawa couplings are natural in Inverse Seesaw models since the small neutrino mass owes its origin to a small Majorana mass of a new set of singlet fermions. Large Yukawas with sub-TeV mass right-handed neutrinos are also possible for certain textures in Type-I seesaw models, so that the above bounds also apply to them. We find that the current Higgs data from the LHC can put bounds on both electron- and muon-type Yukawa couplings of order 10^{-2}.

description: ${\bf Background}$ Despite the global burden of perinatal deaths, there is currently no single, globally-acceptable classification system for perinatal deaths. Instead, multiple, disparate systems are in use world-wide. This inconsistency hinders accurate estimates of causes of death and impedes effective prevention strategies. The World Health Organisation (WHO) is developing a globally-acceptable classification approach for perinatal deaths. To inform this work, we sought to establish a consensus on the important characteristics of such a system. ${\bf Methods}$ A group of international experts in the classification of perinatal deaths were identified and invited to join an expert panel to develop a list of important characteristics of a quality global classification system for perinatal death. A Delphi consensus methodology was used to reach agreement. Three rounds of consultation were undertaken using a purpose built on-line survey. Round one sought suggested characteristics for subsequent scoring and selection in rounds two and three. ${\bf Results}$ The panel of experts agreed on a total of 17 important characteristics for a globally-acceptable perinatal death classification system. Of these, 10 relate to the structural design of the system and 7 relate to the functional aspects and use of the system. ${\bf Conclusion}$ This study serves as formative work towards the development of a globally-acceptable approach for the classification of the causes of perinatal deaths. The list of functional and structural characteristics identified should be taken into consideration when designing and developing such a system.

description: Im Jahr 2015 leitete die Europäische Kommission gegen die Bundesrepublik Deutschland und vier weitere Mitgliedstaaten der Europäischen Union Vertragsverletzungsverfahren wegen der vermeintlichen Unionsrechtswidrigkeit ihrer intra-EU bilateralen Abkommen ein. Der Europäische Gerichtshof hatte sich mit einer ähnlichen Rechtsfrage im Zuge eines Vorabentscheidungsersuchens des Bundesgerichtshofs (Rs. C-284/16 – Achmea) beschäftigt und konstatierte dort, dass Art. 267, 344 AEUV intra-EU bilateralen Investitionsschutzabkommen entgegenstehen. Dadurch stellten sich die folgenden Fragen: Welche Schutzstandards gewährleisten intra-EU bilaterale Investitionsschutzabkommen und welche Alternativen gibt es zu ihnen? Der nachfolgende Beitrag beschäftigt sich mit diesen Problematiken und zeigt verschiedene völker- und unionsrechtliche Schutzinstrumente de lege lata und de lege ferenda auf.

description: "An efficient traffic signal control system is an essential tool to keep smooth, safe traffic environment in most metropolitan cities. In this thesis, artificial intelligence techniques, namely fuzzy logic technologies and evolutionary algorithms were used to implement and optimise a real multi-approach intersection, and at the same time, the pedestrian crossings were also taken into account to increase the complication and difficulty of regulating traffic flow. The main goals of this research are to shorten waiting time for each vehicle and to avoid traffic congestion"-- Abstract.

Corporate voluntary emissions disclosure in Australia: A multi-theoretical accounting perspective

Subjects: classificationCode: 350103
subject: Financial accounting

description: "This study explores the issue of corporate (voluntary) emissions disclosures in Australia during the period 2003/04 through 2009/10. This seven year period covered significant changes in the emissions-related social and political environment, including a change in Australian government, ratification of the Kyoto Protocol by Australia, the introduction of the National Greenhouse and Energy Reporting Act 2007, and a proposed Australian Emissions Trading Scheme (including carbon pricing). A multi-theoretical accounting model is used to explain the disclosures as a transitioning of two political economy theories: Legitimacy and Stakeholder theories. Both theories have been widely used in accounting research for examining the communication between an entity and society in general (Legitimacy Theory) or with certain stakeholders (Managerial Stakeholder Theory)."
