description: Flexibility needs assessment (FNA) refers to the amount of flexibility DSO needs to plan or procure from the flexibility market to avoid probable DNI. The probable DNI are captured using modeling uncer- tainties using generated scenarios that emulate the different realizations which could happen. The scenario generation utilizes the nodal load and generation forecast along with historical forecast errors. Flexibility needs assessment optimal power flow (FNA-OPF) problem is solved for each of the scenarios. The robust FNA, considering the worst-case scenario, if used for flexibility procurement would lead to substantial over-procurement. In order to avoid this, a risk-based index, e.g. a chance constraint (CC), is introduced for procurement. Higher values of the chance constraint would project on to greater risk DSO might have to encounter by facing unresolved DNI. DNI in low voltage grids are often a local problem in which flexible resources in the proximity respond to avoid these incidents. To that end we cluster distribution grids onto connected zones, extend the local search for flexibility resources and propose a zonal bid selection framework that selects flexibility bids from neighborhoods to avoid DNI.

description: The characteristic and distinctive features of the visibility amplitude of interferometric observations for compact objects like stars in the immediate vicinity of the central black hole in our Galaxy are considered. These features are associated with the specifics of strong gravitational scattering of point sources by black holes, wormholes, or black_white holes. The revealed features will help to determine the most important topological characteristics of the central object in our Galaxy: whether this object possesses the properties of only a black hole or also has characteristics unique to wormholes or black_white holes. These studies can be used to interpret the results of optical, infrared, and radio interferometric observations.

description: Air-Cherenkov telescopes have mapped the Galactic plane at TeV energies. Here we evaluate the prospects for detecting the neutrino emission from sources in the Galactic plane assuming that the highest energy photons originate from the decay of pions, which yields a straightforward prediction for the neutrino flux from the decay of the associated production of charged pions. Four promising sources are identified based on having a large flux and a flat spectrum. We subsequently evaluate the probability of their identification above the atmospheric neutrino background in IceCube data as a function of time. We show that observing them over the twenty-year lifetime of the instrumentation is likely, and that some should be observable at the $3\,σ$ level with six years of data. In the absence of positive results, we derive constraints on the spectral index and cut-off energy of the sources, assuming a hadronic acceleration mechanism.

description: We systematically study effects of external perturbations on models describing earthquake fault dynamics. The latter are based on the framework of the Burridge-Knopoff spring-block system, including the cases of a simple mono-block fault, as well as the paradigmatic complex faults made up of two identical or distinct blocks. The blocks exhibit relaxation oscillations, which are representative for the stick-slip behavior typical for earthquake dynamics. Our analysis is carried out by determining the phase response curves of first and second order. For a mono-block fault, we consider the impact of a single and two successive pulse perturbations, further demonstrating how the profile of phase response curves depends on the fault parameters. For a homogeneous two-block fault, our focus is on the scenario where each of the blocks is influenced by a single pulse, whereas for heterogeneous faults, we analyze how the response of the system depends on whether the stimulus is applied to the block having a shorter or a longer oscillation period.

description: Symmetric nonnegative matrix factorization (SNMF) is equivalent to computing a symmetric nonnegative low rank approximation of a data similarity matrix. It inherits the good data interpretability of the well-known nonnegative matrix factorization technique and have better ability of clustering nonlinearly separable data. In this paper, we focus on the algorithmic aspect of the SNMF problem and propose simple inexact block coordinate decent methods to address the problem, leading to both serial and parallel algorithms. The proposed algorithms have guaranteed stationary convergence and can efficiently handle large-scale and/or sparse SNMF problems. Extensive simulations verify the effectiveness of the proposed algorithms compared to recent state-of-the-art algorithms.

description: Measurements of the resistivity anisotropy can provide crucial information about the electronic structure and scattering processes in anisotropic and low-dimensional materials, but quantitative measurements by conventional means often suffer very significant systematic errors. Here we describe a novel approach to measuring the resistivity anisotropy of orthorhombic materials, using a single crystal and a single measurement, that is derived from a $\fracπ{4}$ rotation of the measurement frame relative to the crystallographic axes. In this new basis the transverse resistivity gives a direct measurement of the resistivity anisotropy, which combined with the longitudinal resistivity also gives the in-plane elements of the conventional resistivity tensor via a 5-point contact geometry. This is demonstrated through application to the charge-density wave compound ErTe$_3$, and it is concluded that this method presents a significant improvement on existing techniques in many scenarios.

description: Applying the dispersion approach we compute perturbative QCD corrections to the power suppressed soft contribution of $B \to γ\ell ν$ at leading twist. QCD factorization for the $B \to γ^{\ast}$ form factors is demonstrated explicitly for the hard-collinear transverse polarized photon at one loop, with the aid of the method of regions. While the one-loop hard function is identical to the matching coefficient of the QCD weak current $\bar u \, γ_{μ\perp} \, (1- γ_5) \, b$ in soft-collinear effective theory, the jet function from integrating out the hard-collinear fluctuations differs from the corresponding one entering the factorization formula of $B \to γ\ell ν$. Furthermore, we evaluate the sub-leading power contribution to the $B \to γ$ form factors from the three-particle $B$-meson distribution amplitudes (DAs) at tree level. The soft contribution to the $B \to γ$ form factors from the three-particle $B$-meson DAs is shown to be of the same power compared with the corresponding hard correction, in contrast to the two-particle counterparts. Numerically the next-to-leading-order QCD correction to the soft two-particle contribution in $B \to γ$ form factors will induce an approximately $\left (10 \sim 20 \right) \%$ shift to the tree-level contribution at $λ_B(μ_0)=354 \, {\rm MeV}$. Albeit of power suppression parametrically, the soft two-particle correction can decrease the leading power predictions for the $B \to γ$ form factors by an amount of $\left (10 \sim 30 \right) \%$ with the same value of $λ_B(μ_0)$. Employing the phenomenological model of the three-particle $B$-meson DAs inspired by a QCD sum rule analysis, the three-particle contribution to the $B \to γ$ form factors is predicted to be of ${\cal O} (1 \%)$, at leading order in $α_s$, with the default theory inputs.

description: We study the temperature of rotating probe D7-branes, dual to the temperature of flavored quarks, in the Kuperstein--Sonnenschein holographic model including the effects of spontaneous breakdown of the conformal and chiral flavor symmetry. The model embeds probe D7-branes into the Klebanov-Witten gravity dual of conformal gauge theory, with the embedding parameter, given by the minimal radial extension of the probe, setting the IR scale of conformal and chiral flavor symmetry breakdown. We show that when the minimal extension is positive definite and additional spin is turned on, the induced world volume metrics on the probe admit thermal horizons and Hawking temperatures despite the absence of black holes in the bulk. We find the scale and behavior of the temperature in flavored quarks are determined notably by the IR scale of symmetry breaking, and by the strength and sort of external fields. We also derive the energy--stress tensor of the rotating probe and study its backreaction and energy dissipation. We show that at the IR scale the backreaction is non-negligible and find the energy can flow from the probe to the bulk, dual to the energy dissipation from the flavor sector into the gauge theory.

description: Magnetic hyperthermia is a new type of cancer treatment designed for overcoming resistance to chemotherapy during the treatment of solid, inaccessible human tumors. The main challenge of this technology is increasing the local tumoral temperature with minimal side effects on the surrounding healthy tissue. This work consists of an in vitro study that compared the effect of hyperthermia in response to the application of exogenous heating (EHT) sources with the corresponding effect produced by magnetic hyperthermia (MHT) at the same target temperatures. Human neuroblastoma SH-SY5Y cells were loaded with magnetic nanoparticles (MNPs) and packed into dense pellets to generate an environment that is crudely similar to that expected in solid micro-tumors, and the above-mentioned protocols were applied to these cells. These experiments showed that for the same target temperatures, MHT induces a decrease in cell viability that is larger than the corresponding EHT, up to a maximum difference of approximately 45\% at T = 46°C. An analysis of the data in terms of temperature efficiency demonstrated that MHT requires an average temperature that is 6°C lower than that required with EHT to produce a similar cytotoxic effect. An analysis of electron microscopy images of the cells after the EHT and MHT treatments indicated that the enhanced effectiveness observed with MHT is associated with local cell destruction triggered by the magnetic nano-heaters. The present study is an essential step toward the development of innovative adjuvant anti-cancer therapies based on local hyperthermia treatments using magnetic particles as nano-heaters.

description: Coherent condensates appear as emergent phenomena in many systems, sharing the characteristic feature of an energy gap separating the lowest excitations from the condensate ground state. This implies that a scattering object, moving through the system with high enough velocity for the excitation spectrum in the scatter frame to become gapless, can create excitations at no energy cost, initiating the breakdown of the condensate. This limit is the well-known Landau velocity. While, for the neutral Fermionic superfluid 3He-B in the T=0 limit, flow around an oscillating body displays a very clear critical velocity for the onset of dissipation, here we show that for uniform linear motion there is no discontinuity whatsoever in the dissipation as the Landau critical velocity is passed and exceeded. Since the Landau velocity is such a pillar of our understanding of superfluidity, this is a considerable surprise, with implications for the understanding of the dissipative effects of moving objects in all coherent condensate systems.

description: The ARCADE radio excess and EDGES measurement remain puzzling. A link between the two has been previously considered, however, in this work we highlight an important related effect that was not analyzed in detail before. By performing cosmological thermalization calculations with soft photon injection using {\tt CosmoTherm}, we show that for the 21 cm signal generation the interplay between enhanced radio spectral distortions and the associated heating can hide a significant radio excess before the reionzation era. We illustrate this effect for a simple power-law soft photon source in decaying particle scenarios. Even if simplistic, the uncovered link between CMB spectral distortions and 21 cm cosmology should apply to a much broader range of scenarios. This could significantly affect the constraints derived from existing and future 21 cm observations on the evolution of the ambient radio background. In particular, scenarios that would be ruled out by existing data without heating could become viable solutions once the heating is accounted for in the modelling. Our calculations furthermore highlight the importance of global 21 cm observations reaching into the dark ages, where various scenarios can potentially be distinguished.

description: One key factor that limits the predictive power of molecular dynamics simulations is the accuracy and transferability of the input force field. Force fields are challenged by heterogeneous environments, where electronic responses give rise to biologically important forces such as many-body polarisation and dispersion. The importance of polarisation was recognised early-on and described by Cochran in 1959 [Philosophical Magazine 4 (1959) 1082-1086]. However, dispersion forces are still treated at the two-body level and in the dipole limit, although the importance of three-body terms in the condensed phase was demonstrated by Barker in the 1980s [Phys. Rev. Lett. 57 (1986) 230-233]. A way of treating both polarisation and dispersion on an equal basis is to coarse grain the electrons a molecular moiety to a single quantum harmonic oscillator, as suggested as early as the 1960s by Hirschfelder, Curtiss and Bird [The Molecular Theory of Gases and Liquids (1954)]. This treatment, when solved in the strong coupling limit, gives all orders of long-range forces. In the last decade, the tools necessary to exploit this strong coupling limit have been developed, culminating in a transferable model of water with excellent predictive power across the phase diagram. This transferability arises since the environment identifies the form of long range interactions, rather than the expressions selected by the modeller. Here, we discuss the role of electronic coarse-graining in predictive multiscale materials modelling and describe the first implementation of the method in a general purpose molecular dynamics software, QDO_MD.

Beyond totalitarian nostalgia: a critical urban reception study of historical drama on contemporary Chinese television
Creators: name: Guo, Dawei
Publisher: name: University of Westminster
Year: 2012

description: From the mid-1990s a wave of dramatic serials featuring the legendary figures of China’s bygone dynasties has emerged in dramatic programming on Chinese primetime television. The commercialization of mass media and the rise of media consumerism in China since the early 1990s have fostered the emergence of these historical dramas on television. Set during the dynasty era, these television historical dramas have been at the forefront in articulating political and legal principles based on the Confucian-influenced traditional Chinese culture. Although media scholars have interpreted the popularity of the television historical dramas as a revival of Confucianism, virtually no empirical research has been done to explore how Chinese audiences relate their viewing experiences to the revival of Confucianism according to their own social and cultural conditions. This thesis presents a qualitative audience study of how the historical dramas are understood and socially and culturally valued in contemporary China, taking into account personal, social, historical and cultural issues that relate to viewers’ engagement with this television genre. Between late September 2007 and early April 2008, the author carried out his fieldwork audience research in two urban settings in China, the city of Beijing and that of Changsha. 10 focus groups and 11 in-depth interviews were conducted involving more than 60 respondents from young adult and middle-aged audience groups. According to the author’s fieldwork data analysis, the ways that the Chinese audience engages with the historical drama are far more complex than generally thought; rather than insist on a literal interpretation of the drama text, the audience engages with the historical television drama in quite a divergent way due to his or her age, gender, life stage and socio-cultural status. Meanwhile, informed by the Grounded Theory, the author identified two text-based interpretive frameworks that are adopted by the respondents across all the focus groups and in-depth interviews in their understanding and evaluation of the historical drama text. These two interpretive frameworks include the framework of fact/fiction and that of ‘classic-ness’. To conclude, the author argues that the Chinese audience’s response to the historical drama goes beyond a literal, political sense of totalitarian nostalgia; it is characterised by an increasingly more liberal, diverse and indeed open-ended engagement with the historical drama text. Nevertheless, a critical re-evaluation of Maoist revolutionary classic literary works is manifested within that engagement process.

description: L'office fédéral de la statistique (OFS) relève à l'heure actuelle un taux deux fois plus élevé d'élèves garçons que d'élèves filles dans les classes de développement du secondaire I. Par ailleurs, de nombreuses recherches démontrent la place prédominante des élèves garçons dans les classes de l'enseignement obligatoire, par rapport aux élèves filles, tant au niveau du temps de parole qui leur est alloué que par l'attention plus individualisée qui leur est accordée par l'enseignant.e. Dès lors, nous posons la question de la place des filles, en infériorité numérique, dans les classes de développement. Ainsi, la présente recherche vise à questionner la place des filles dans les classes de développement du secondaire I et se déroule en deux temps. Elle cible, tout d'abord, différents phénomènes empiriques prenant place dans les classes au moyen d'observations réalisées dans trois classes de développement d'un établissement secondaire. Dans un deuxième temps, elle questionne la perception que les filles se font de la place qu'elles occupent et qui leur est attribuée au sein du groupe classe, tant par l'enseignant.e que par les garçons, au moyen d'entretiens semi-directifs. Les données recueillies et analysées permettent de mettre en évidence différentes problématiques telles qu'une faible estime de soi des élèves filles interrogées et leur attribution aux garçons, outre leur omniprésence dans le groupe, d'une certaine propension à la violence sous plusieurs formes et d'une volonté de domination des filles. L'accent est également mis sur l'importance de la présence de plusieurs camarades filles dans le groupe classe pour une intégration facilitée.

description: Mit COVIAGE (2014–2017) und SELODY (2019– 2021) wurden in der jüngeren Vergangenheit bereits zwei wissenschaftliche Studien zum Einfluss einer Sehbeeinträchtigung auf die Alltagsbewältigung und Lebensgestaltung publiziert. Während sich COVIAGE dem «Erfolgsrezept» des erfolgreichen Alterns widmete, konzentrierte sich SELODY auf die Auswirkungen einer Sehbeeinträchtigung auf die Partnerschaft.

In einer Studie an der ZHAW machten wir sprichwörtlich einen Schritt zurück und rückten den Erblindungsprozess in den Fokus, ohne uns dabei auf eine Altersgruppe oder einen Lebensbereich zu beschränken. Mithilfe sog. Erzählinterviews wurde untersucht, mit (a) welchen Herausforderungen Menschen im Prozess des Sehverlusts konfrontiert sind und (b) welche Ressourcen deren Bewältigung erleichtern. Die Studienergebnisse sollen u. a. Fachpersonen und Angehörige dabei unterstützen, ein Verständnis für die Erlebniswelt sehbeeinträchtigter Menschen zu entwickeln.

An unserer Studie nahmen 12 Menschen im Alter von 23 bis 80 Jahren teil, welche aufgrund einer degenerativen Augenerkrankung hochgradig sehbeeinträchtigt oder erblindet waren. Im Unterschied zu den beiden Vorgängerstudien mussten die Teilnehmenden weder einen Fragebogen ausfüllen noch auf die Fragen eines Interviewleitfadens antworten. Stattdessen wurden sie dazu eingeladen, ihre persönliche Geschichte des Sehverlusts zu erzählen, ohne dabei unterbrochen zu werden. Dadurch erhielten die Teilnehmenden Gestaltungsfreiheit in der Schilderung der eigenen Erfahrungen.

Die Ergebnisinterpretation profitierte von den verschiedenen Perspektiven einer erblindeten Studentin und eines sehenden Studenten. Präsentiert werden nachfolgend exemplarisch Herausforderungen und Ressourcen zu vier Themenfeldern. Mithilfe echter Zitate aus den Interviews werden theoretische Inhalte anschaulich und lebendig. Die beiden fiktiven Figuren Alexandra und Kai stehen dabei stellvertretend für die Gesamtstichprobe.

description: We use x-ray absorption spectroscopy as well as its linear and circular magnetic dichroisms to characterize relevant interactions and energy scales in the surface intermetallic CePt$_5$/Pt(111). The experiments provide insight into crystal field splitting, effective paramagnetic moments, their Kondo screening and mutual interactions and thus into many aspects which typically determine the low temperature behavior of correlated rare earth compounds. Exploiting the tuneability of Ce valence through the thickness dependent epitaxial strain at the CePt$_5$/Pt(111) interface, we are able to systematically investigate the impact of hybridization strength on these interactions. Considerable Kondo screening is indeed observed at all CePt$_5$ thicknesses, and found to be strongest in case of strongest hybridization. While the magnetic response is commensurate with an impurity Kondo scale of $T_K \gtrsim 10^2$ K for specimen temperatures $T \gtrsim 30$ K, this is no longer the case at lower temperature. Its detailed study by XMCD at one specific thickness of CePt$_5$ reveals an anomaly of the susceptibility at $T^* \approx 25$ K instead, which we tentatively associate with the onset of lattice coherence. At lowest temperature we observe paramagnetic saturation with a small Ce $4f$ saturation magnetization. Within the framework of itinerant $4f$ electrons, saturation is due to a field induced Lifshitz transition involving a very heavy band with correspondingly small degeneracy temperature of $T_F \approx 7$ K. This small energy scale results in the persistence of Curie-Weiss behavior across the entire range of experimentally accessible temperatures ($T \gtrsim 2$ K). Our work highlights the potential of magnetic circular dichroism studies in particular for Kondo and heavy fermion materials, which so far has remained largely unexplored.

Our search used the Rapid ASKAP Continuum Survey, which covered the entire sky south of declination $+41^{\circ}$ ($\sim34,000$ square degrees) at a central frequency of 887.5 MHz, the Variables and Slow Transients Pilot Survey, which covered $\sim5,000$ square degrees per epoch (887.5 MHz), and other ASKAP pilot surveys, which covered $\sim200-2000$ square degrees with 2-12 hour integration times. We crossmatched radio sources found in these surveys over a two-year period, from April 2019 to August 2021, with 440 previously identified optical novae, and found radio counterparts for four novae: V5668 Sgr, V1369 Cen, YZ Ret, and RR Tel. Follow-up observations with the Australian Telescope Compact Array confirm the ejecta thinning across all observed bands with spectral analysis indicative of synchrotron emission in V1369 Cen and YZ Ret. Our light-curve fit with the Hubble Flow model yields a value of $1.65\pm 0.17 \times 10^{-4} \rm \:M_\odot$ for the mass ejected in V1369 Cen. We also derive a peak surface brightness temperature of $250\pm80$ K for YZ Ret. Using Hubble Flow model simulated radio lightcurves for novae, we demonstrate that with a 5$σ$ sensitivity limit of 1.5 mJy in 15-min survey observations, we can detect radio emission up to a distance of 4 kpc if ejecta mass is in the range $10^{-3}\rm \:M_\odot$, and upto 1 kpc if ejecta mass is in the range $10^{-5}-10^{-3}\rm \:M_\odot$. Our study highlights ASKAP's ability to contribute to future radio observations for novae within a distance of 1 kpc hosted on white dwarfs with masses $0.4-1.25\:\rm M_\odot$ , and within a distance of 4 kpc hosted on white dwarfs with masses $0.4-1.0\:\rm M_\odot$.

description: The Tully-Fisher relation (TFR) links the stellar mass of a disk galaxy, $M_{\rm str}$, to its rotation speed: it is well approximated by a power law, shows little scatter, and evolves weakly with redshift. The relation has been interpreted as reflecting the mass-velocity scaling ($M\propto V^3$) of dark matter halos, but this interpretation has been called into question by abundance-matching (AM) models, which predict the galaxy-halo mass relation to be non-monotonic and rapidy evolving. We study the TFR of luminous spirals and its relation to AM using the EAGLE set of $Λ$CDM cosmological simulations. Matching both relations requires disk sizes to satisfy constraints given by the concentration of halos and their response to galaxy assembly. EAGLE galaxies approximately match these constraints and show a tight mass-velocity scaling that compares favourably with the observed TFR. The TFR is degenerate to changes in galaxy formation efficiency and the mass-size relation; simulations that fail to match the galaxy stellar mass function may fit the observed TFR if galaxies follow a different mass-size relation. The small scatter in the simulated TFR results because, at fixed halo mass, galaxy mass and rotation speed correlate strongly, scattering galaxies along the main relation. EAGLE galaxies evolve with lookback time following approximately the prescriptions of AM models and the observed mass-size relation of bright spirals, leading to a weak TFR evolution consistent with observation out to $z=1$. $Λ$CDM models that match both the abundance and size of galaxies as a function of stellar mass have no difficulty reproducing the observed TFR and its evolution.

description: The Standard Model is one of the main intellectual achievements for about the last 50 years, a result of many theoretical and experimental studies. In this lecture a brief introduction to the electroweak part of the Standard Model is given. Since the Standard Model is a quantum field theory, some aspects for understanding of quantization of abelian and non-abelian gauge theories are also briefly discussed. It is demonstrated how well the electroweak Standard Model works in describing a large variety of precise experimental measure- ments at lepton and hadron colliders.

description: In heavy quark limit, the lowest-lying charmed baryons with two light quarks can form an SU(3) triplet and sextet. The $Ξ_c$ in the SU(3) triplet and $Ξ_c'$ in the sextet have the same $J^{PC}$ quantum number and can mix due to the finite charm quark mass and the fact the strange quark is heavier than the up/down quark. We explore the $Ξ_c$-$Ξ_c'$ mixing by calculating the two-point correlation functions of the $Ξ_c$ and $Ξ_c'$ baryons from lattice QCD. Based on the lattice data, we adopt two independent methods to determine the mixing angle between $Ξ_c$ and $Ξ_c'$. After making the chiral and continuum extrapolation, it is found that the mixing angle $θ$ is $1.2^{\circ}\pm0.1^{\circ}$, which seems insufficient to account for the large SU(3) symmetry breaking effects found in weak decays of charmed baryons.

description: Dark Matter (DM) may have a relic density that is in part determined by a particle/antiparticle asymmetry, much like baryons. If this is the case, it can accumulate in stars like the Sun to sizable number densities and annihilate to Standard Model (SM) particles including neutrinos. We show that the combination of neutrino telescope and direct detection data can be used in conjunction to determine or constrain the DM asymmetry from data. Depending on the DM mass, the current neutrino data from Super-K and IceCube give powerful constraints on asymmetric DM unless its fractional asymmetry is $\lesssim 10^{-2}$. Future neutrino telescopes and detectors like Hyper-K and KM3NeT can search for the resulting signal of high-energy neutrinos from the center of the Sun. The observation of such a flux yields information on both the DM-nucleus cross section but also on the relative abundances of DM and anti-DM.

description: We investigate the thermodynamic and transport properties of silver-substituted BaFe2As2 (122) crystals, up to ~4.5%. Similar to other transition-metal substitutions in 122, Ag diminishes the antiferromagnetic (TN) and structural (TS) transition temperatures, but unlike other electron-doped 122s, TN and TS coincide without splitting. Although magnetism drops precipitously to TN = 84 K at doping x = 0.029, it only weakly changes above this x, settling at TN = 80 K at x = 0.045. Compared to this persistent magnetism in Ag-122, doping other group 11 elements of either Cu or Au in 122 diminished TN and induced superconductivity near TC = 2 K at x = 0.044 or 0.031, respectively. Ag-122 crystals show reflective surfaces with surprising thicker cross sections for x >= 0.019, the appearance that is in contrast to the typical thin stacked layered feature seen in all other flux-grown x122 and lower Ag-122. This physical trait may be a manifest of intrinsic weak changes in c-lattice and TN. Our theoretical calculations suggest that Ag doping produces strong electronic scattering and yet a relatively small disruption of the magnetic state, both of which preclude superconductivity in this system.

description: The aim of this study was to translate the English version of the Foot Posture Index (FPI-6) into Turkish and to examine its psychometric properties. After the forward-backward translation process, the internal consistency and intra – and inter-rater reliability were evaluated by using Cronbach’s α and Intraclass Correlation Coefficient (ICC2,k) (two-way random effects model with absolute agreement type), respectively. The agreement between reliability assessments was investigated by the standard error of measurement (SEM) and the minimal detectable change (MDC95%). Criterion validity was assessed in relationship between the Turkish FPI-6 and Foot Function Index (FFI) and the American Orthopedic Foot and Ankle Society (AOFAS). The study was completed with 45 patients with foot/ankle problems. The internal consistency (Cronbach’s α = 0.85; 0.78, respectively), intra-reliability (ICC2,k = 0.96; 0.94, respectively), and inter-reliability (ICC2,k = 0.93; both of them) of the Turkish version of the FPI-6 were excellent for the dominant and non-dominant lower limb. The SEM was low, and the agreement was considered to have high absolute reliability, as demonstrated by the smallest change in measurement error. The Turkish FPI-6 also had moderate correlations with the FFI and AOFAS (p < .05). It has been proven that the Turkish FPI-6 is valid and reliable and can be used by Turkish-speaking researchers and clinicians in patients with various foot-ankle problems.
Restorative justice as a disciplinary tool: Aperspective from Singapore
Creators: name: Wong, Julia
Publisher: name: University of Westminster
Year: 2014

description: This thesis focuses on the use of Restorative Practices (RP) in two Singapore Secondary Schools. Relying mainly on the use of in-depths interviews with 149 students and 30 teachers, this study examines how the two schools’ contexts and cultural demands affect the definitions, adaptations and practices of RP. The research shows that RP is predominantly used as a disciplinary tool in order to uphold existing social norms. Many teachers could articulate the non-negotiables that must be secured in all circumstances such as those of ‘non-domination’ and ‘respectful listening’. Teachers spoke of RP as primarily about building relationships and it is about doing things with (and not to) students. However we see instances of teachers’ domination over students when teachers dictated the type of answers students were to write down on their RP forms. The relationship between corporal punishment and RP is also examined. While many teachers believed that ‘pure RP’ should not co-exist with caning, they still preferred the status quo and argued that RP should be taken as a complementary framework alongside existing corrective practices and punishment, rather than as a replacement to the existing disciplinary framework. Through an analysis of a case conference, we see how caning is retained in part because it is taken to be the utmost symbol of hard treatment that is required to express condemnation in cases of major offences. Finally, the specific context of the school is important in analysing participants’ ability to engage in RP processes such as class conferences or circles. The class is not a homogenous community that is resolving issues collectively but consists of a group of individuals who belong to a class that is attempting to resolve things but the very coming together as a class to resolve and discuss issues creates difficulty for things to get done because of the group dynamics involved.
