'A sort of juridical phantasm' : the criminal law’s (lack of) engagement with lesbianism
Creators: name: Derry, Caroline
Publisher: name: University of Westminster
Year: 2007

description: This thesis examines the ways in which the criminal justice system of England and Wales has regulated, failed or refused to regulate lesbiainism. It identifies the overarching approach as one of silencing, in which lesbianism is not simply ignored or unimaginable but is deliberately excluded from legal discourses. However, the existence of such a policy cannot alone explain the complex ways in which lesbianism has been regulated, and so two particular issues are explored in detail. First, in what ways has the policy of silencing been breached? Historical and contemporary criminal prosecutions over three centuries are identified and their significance examined. That significance can be fully understood only in the context of surrounding social and legal developments which are also considered. Second, the evolution of silencing itself is explored. From the profound changes in popular and medical understandings of sexuality which occurred in the eighteenth and nineteenth centuries to the growth of lesbian visibility and political activism in the twentieth and twenty-first, the contexts in which silencing operates have altered dramatically. Further, the law itself has moved for the first time to an avowedly non-discriminatory, gender-neutral approach with the Sexual Offences Act 2003. In consequence, silencing itself has also had to change. As simple denial of lesbianism's existence has ceased to be feasible, this thesis describes the new forms which silencing has taken in response. Third, the thesis considers the implications of the criminal legal system's approaches for the theoretical underpinnings of lesbian theory and activism. Liberal theories, queer theories and radical feminism are all examined in this context. Their adequacy in explaining and responding to the criminal law's treatment of lesbianism is analysed, and the significance of this analysis for future directions in lesbian activism explored. This thesis offers a significant contribution to knowledge in two respects. First, although many of the cases discussed here have been published elsewhere and subjected to varying degrees of academic analysis, this is the first systematic account of the regulation of lesbianism by the criminal justice system. Thus the discussion of common themes and historical developments is novel. Second, most of the cases have hitherto been considered from a historical rather than legal perspective, while many of the contemporary cases have not previously been considered from a broadly radical feminist perspective. Further, the analysis of the applicability of queer and radical feminist theories to this particular area of the criminal law is also new. This thesis therefore demonstrates the exercise of independent critical powers.

Mechanical dissipation at a tip-induced Kondo onset

description: The onset or demise of Kondo effect in a magnetic impurity on a metal surface can be triggered, as often observed, by the simple mechanical nudging of a tip. This mechanically-driven quantum phase transition must reflect in a corresponding mechanical dissipation peak; yet, this kind of effect has not been focused upon so far. Aiming at the simplest theoretical modeling, we initially treat the impurity as a non-interacting resonant level turned cyclically on and off, and obtain a dissipation per cycle which is proportional to the hybridization $Γ$, with a characteristic temperature dependent resonant peak value. A better treatment is obtained next by solving an Anderson impurity model by numerical renormalization group. Here, many body effects yield a dissipation whose peak value is now proportional to $T_K |\log T|$ so long as $T\sim T_K$, followed for $T\sim Γ$ by a second high temperature regime where dissipation is proportional to $Γ|\log T|$. The detectability of Kondo mechanical dissipation in atomic force microscopy is discussed.

Crime and disorder
Creators: name: Darke, Sacha
Publisher: name: University of Westminster
Year: 2007

description: This thesis investigates growing use of civil and public law orders as tools of crime control by crime prevention partnerships. This development has been little explored in criminology. The proliferation of crime prevention partnerships is viewed by many criminologists as forming part of a bifurcation in criminal policy between serious crime and anti-social behaviour, in which the 'enforcement approach' of the criminal justice system is being focused upon the former and a non-legal 'partnership approach' advanced for the control of the latter. It is argued that the 'partnership approach' runs a risk of becoming an extension of and not an alternative to the 'enforcement approach' of the criminal justice system. In investigating this risk, it is intended that this thesis should contribute to criminology in two ways. The first contribution is an investigation of the theoretical potential for the local to become a site of authoritarian crime control. The second is an investigation of the extent this potential is being realised in England and Wales. Empirical research centred on the development of crime prevention strategies in implementing the Crime and Disorder Act 1998. Fieldwork focused on the development of metropolitan borough strategies in twenty-one London boroughs, and a police sector and two social housing estate strategies in the borough of Westminster. Resort to civil and public law orders was found to be significant to the approach taken by the majority of London boroughs studied, including Westminster. One of the estate strategies at Westminster was found to be as authoritarian as the borough strategy, but the other estate strategy and the police sector strategy were not. Punitive views were not encountered among local practitioners on any of the three sites. Punitive views were encountered among local residents on the police sector, but not on either of the estates. Once the peculiarities of the institutions and areas studied were taken into account, it was concluded that there is a significant risk that crime prevention partnerships will take an authoritarian approach to crime control unless they are located in areas where there is a strong sense of geographical community, and their policies are shaped by local practitioners and local residents.

The evaporation valley in the Kepler planets

description: A new piece of evidence supporting the photoevaporation-driven evolution model for low-mass, close-in exoplanets was recently presented by the California-Kepler-Survey. The radius distribution of the Kepler planets is shown to be bimodal, with a ``valley' separating two peaks at 1.3 and 2.6 Rearth. Such an ``evaporation-valley' had been predicted by numerical models previously. Here, we develop a minimal model to demonstrate that this valley results from the following fact: the timescale for envelope erosion is the longest for those planets with hydrogen/helium-rich envelopes that, while only a few percent in weight, double its radius. The timescale falls for envelopes lighter than this because the planet's radius remains largely constant for tenuous envelopes. The timescale also drops for heavier envelopes because the planet swells up faster than the addition of envelope mass. Photoevaporation, therefore, herds planets into either bare cores ~1.3 Rearth, or those with double the core's radius (~2.6 Rearth). This process mostly occurs during the first 100 Myrs when the stars' high energy flux are high and nearly constant. The observed radius distribution further requires that the Kepler planets are clustered around 3 Mearth in mass, are born with H/He envelopes more than a few percent in mass, and that their cores are similar to the Earth in composition. Such envelopes must have been accreted before the dispersal of the gas disks, while the core composition indicates formation inside the ice-line. Lastly, the photoevaporation model fails to account for bare planets beyond ~30-60 days, if these planets are abundant, they may point to a significant second channel for planet formation, resembling the Solar-System terrestrial planets.

description: Given an $n$-gon, the poset of all collections of pairwise non-crossing diagonals is isomorphic to the face poset of some convex polytope called \textit{associahedron}. We replace in this setting the $n$-gon (viewed as a disc with $n$ marked points on the boundary) with an arbitrary oriented surface with a number of labeled marked points ("vertices"). With appropriate definitions we arrive at cell complexes $\mathcal{D}$ (generalization of) and its barycentric subdivision $\mathcal{BD}$. The complex $\mathcal{D}$ generalizes the associahedron. If the surface is closed, the complex $\mathcal{D}$ (as well as $\mathcal{BD}$) is homotopy equivalent to the space of metric ribbon graphs $RG_{g,n}^{met}$, or, equivalently, to the decorated moduli space $\widetilde{\mathcal{M}}_{g,n}$. For bordered surfaces, we prove the following: (1) Contraction of a boundary edge does not change the homotopy type of the support of the complex. (2) Contraction of a boundary component to a new marked point yields a forgetful map between two diagonal complexes which is homotopy equivalent to the Kontsevich's tautological circle bundle. Thus, contraction of a boundary component gives a natural simplicial model for the tautological bundle. As an application, we compute the psi-class, that is, the first Chern class in combinatorial terms. The latter result is an application of the local combinatorial formula. (3) In the same way, contraction of several boundary components corresponds to Whitney sum of the tautological bundles.

description: We study the axial U(1) symmetry at finite temperature in two-flavor lattice QCD. Employing the Mobius domain-wall fermions, we generate gauge configurations slightly above the critical temperature Tc with different lattice sizes L = 2-4 fm. Our action allows frequent topology tunneling while keeping good chiral symmetry close enough to that of overlap fermions. This allows us to recover full chiral symmetry by an overlap/domain-wall reweighting. Above the phase transition, a strong suppression of the low-lying modes is observed in both of overlap and domain-wall Dirac spectra. We, however, find a sizable violation of the Ginsparg-Wilson relation in the Mobius domain-wall Dirac eigenmodes, which dominates the signals of the axial U(1) symmetry breaking near the chiral limit. We also find that the use of overlap fermion only in the valence sector is dangerous since it suffers from the artifacts due to partial quenching. Reweighting the Mobius domain-wall fermion determinant to that of the overlap fermion, we observe the axial U(1) breaking to vanish in the chiral limit, which is stable against the changes of the lattice volume and lattice spacing.

description: Abstract: Parish - parish church - patrocinium - rectory. These have been traditional terms in the vocabulary of the faithful for centuries, as well as in canon law. In connection with the far-reaching reorganisation of territorial pastoral care in the German dioceses, which encompasses all areas of church work, questions of canon law arise, not all of which seem at first glance to be clearly and unambiguously regulated by universal canon law. Neither the Codex Iuris Canonici nor the Parish Instruction of 2021 provide clear answers to every legal question regarding the legal situation and its interpretation. Nevertheless, questions of detail are often of considerable importance because they will have a great influence on practical pastoral care in the future reorganised pastoral structures. This article aims to provide answers as to how the terms addressed can be interpreted in conformity with the law and what consequences

description: This article is concerned with causal structures, which are defined as a field of tangentially non-degenerate projective hypersurfaces in the projectivized tangent bundle of a manifold. The local equivalence problem of causal structures on manifolds of dimension at least four is solved using Cartan's method of equivalence, leading to an $\{e\}$-structure over some principal bundle. It is shown that these structures correspond to parabolic geometries of type $(D_n,P_{1,2})$ and $(B_{n-1},P_{1,2})$, when $n\geq 4$, and $(D_3,P_{1,2,3})$. The essential local invariants are determined and interpreted geometrically. Several special classes of causal structures are considered including those that are a lift of pseudo-conformal structures and those referred to as causal structures with vanishing Wsf curvature. A twistorial construction for causal structures with vanishing Wsf curvature is given.

description: In these proceedings, we review recent advances in applying quantum computing to lattice field theory. Quantum computing offers the prospect to simulate lattice field theories in parameter regimes that are largely inaccessible with the conventional Monte Carlo approach, such as the sign-problem afflicted regimes of finite baryon density, topological terms, and out-of-equilibrium dynamics. First proof-of-concept quantum computations of lattice gauge theories in (1+1) dimensions have been accomplished, and first resource-efficient quantum algorithms for lattice gauge theories in (1+1) and (2+1) dimensions have been developed. The path towards quantum computations of (3+1)-dimensional lattice gauge theories, including Lattice QCD, requires many incremental steps of improving both quantum hardware and quantum algorithms. After reviewing these requirements and recent advances, we discuss the main challenges and future directions.

The European Social Forum and the Internet: a case of communications networks and collective action
Creators: name: Kavada, Anastasia
Publisher: name: University of Westminster
Year: 2007

description: Distinguished by its transnational scale, non-hierarchical organizing, and diverse composition, the 'movement for alternative globalization' is thought to partly derive this combination of characteristics from its use of the internet. My research is an attempt to explore this relationship by investigating the use of email lists for the preparation of the European Social Forum (ESF) in London in October 2004, one of the largest gatherings of the movement in Europe. Focusing on the processes of organizing, decision-making and collective identity formation, my study employed a combination of methods, including a preliminary survey, in-depth interviews, as. well as content analysis of the main ESF email lists. In terms of organizing, my thesis revealed that email lists are instrumental in constructing a flexible and polycentric organizing structure. They were also used extensively to widen up participation to the face-to-face organizing meetings, but also to legitimate the decision-making system and conceal its asymmetries of power. Furthermore, every list constituted a different 'site of identization' whose affordances for identity construction depended on its size, scale, and composition. In that respect, email lists constituted an infrastructure for the development of multiple identities within the movement. However, the lack of physical proximity and the limited capacity for conveying emotive content constrained the potential of email lists to foster relationships of trust and shared opinions which were instead facilitated by face-to-face communication. Overall, my thesis has identified a series of mechanisms and dynamics whose point of equilibrium determines the state of the movement at any point in time. In that respect, email and email lists tend to foster opening, divergence, multiplicity, and individuality, while face-to-face communication tends to generate closing, convergence, unity, and collectiveness. It is therefore the combination of these two forms of communication that helps the movement to have seemingly contrasting characteristics: to be united in difference or to be a collective that affirms individual subjectivity. However, my study has further shown that the capacity of the internet to foster such dynamics also depends on the specific cultures of organizing, political priorities, and ideological backgrounds of the people using it.

description: Controlled quantum systems such as ultracold atoms can provide powerful platforms to study non-equilibrium dynamics of closed many-body quantum systems, especially since a complete theoretical description is generally challenging. In this Letter, we present a detailed study of the rich out-of-equilibrium dynamics of an adjustable number $N$ of uncorrelated condensates after connecting them in a ring-shaped optical trap. We observe the formation of long-lived supercurrents and confirm the scaling of their winding number with $N$ in agreement with the geodesic rule. Moreover, we provide insight into the microscopic mechanism that underlies the smoothening of the phase profile.

description: Barocaloric effect in vulcanized natural rubber (V-NR) has been investigated. Direct measurements of the temperature change (ΔT) around room temperature (283-333 K) resulted in large values, above 10 K, for a pressure change of 173 MPa. A power law was proposed to fit ΔT as function of the maximum pressure, showing to be suitable for the barocaloric effect in V-NR. Strain was measured as a function of temperature at constant pressures in order to obtain the isothermal entropy change (ΔST). At 293 K, we obtained a ΔST of 21 J.kg-1K-1 for a pressure change of only 43.4 MPa. The results presented in this work are compared with those reported recently for PVDF-TrFE-CTFE polymer, showing a better barocaloric performance for V-NR in similar temperature and pressure ranges. These findings evidence the high potential of V-NR for application in solid-state refrigeration based on confined compression, opening new possibilities for i-caloric materials.

description: A five-dimensional gravity theory, motivated by the brane-world picture, with Kaluza scalar in the 5 - dimensional metric as $g_{55}(r); r=\sqrt{x^2+y^2+z^2}$, is considered near the possible singularity (small distance scales where gravity is strong) and is shown to give rise to a positive contribution to the Raychaudhuri equation. This inhibits the focusing of world lines and contributes to non - focusing of the worldlines in the 5-dimensional space. It is also shown that the results extend to time dependent cases such as those relevant for black hole interiors and cosmology.

description: We study the gravitational waves produced by the collision of the bubbles as a probe for the cosmological first order QCD phase transition, considering heavy static quarks. Using AdS/QCD and the correspondence between a first order Hawking-Page phase transition and confinement-deconfinement phase transition, we find the spectrum and the strain amplitude of the gravitational wave within the hard and soft wall models. We postulate the duration of the phase transition corresponds to the evaporation time of the black hole in the five dimensional dual gravity space, and thereby obtain a bound on the string length in the space and correspondingly on the duration of the QCD phase transition. We also show that IPTA and SKA detectors will be able to detect these gravitational waves, which can be an evidence for the first order deconfinement transition.

title: Tests for Jumps in Yield Spreads
Creators: name: Winkelmann, Lars

Publisher: name: Hertie School
Year: 2023

description: This paper studies high-frequency econometric methods to test for a jump in the spread of bond yields. We propose a coherent inference procedure that detects a jump in the yield spread only if at least one of the two underlying bonds displays a jump. Ignoring this inherent connection by basing inference only on a univariate jump test applied to the spread tends to overestimate the number of jumps in yield spreads and puts the coherence of test results at risk. We formalize the statistical approach in the context of an intersection union test in multiple testing. We document the relevance of coherent tests and their practicability via simulations and real data examples.

description: A survey of a variety of computational procedures for finding the mean first passage times in Markov chains is presented. The author recently developed a new accurate computational technique, an Extended GTH Procedure, Hunter (Special Matrices, 2016) similar to that developed by Kohlas (Zeit. fur Oper. Res., 1986). In addition, the author recently developed a variety of new perturbation techniques for finding key properties of Markov chains including finding the mean first passage times, Hunter (Linear Algebra and its Applications, 2016). These recently developed procedures are compared with other procedures including the standard matrix inversion technique using the fundamental matrix (Kemeny and Snell, 1960), some simple generalized matrix inverse techniques developed by Hunter (Asia Pacific J. Oper. Res., 2007), and some modifications to the FUND technique of Heyman (SIAM J Matrix Anal. and Appl., 1995). MATLAB is used to compute errors and estimate computation times when the techniques are used on some test problems that have been used in the literature together with some large sparse state-space cases. For accuracy a preference for the procedure of the author is exhibited for the test problems. However it appears that the procedure, as presented, requires longer computational times.

description: Model-based prediction of stochastic noise in biomolecular reactions often resorts to approximation with unknown precision. As a result, unexpected stochastic fluctuation causes a headache for the designers of biomolecular circuits. This paper proposes a convex optimization approach to quantifying the steady state moments of molecular copy counts with theoretical rigor. We show that the stochastic moments lie in a convex semi-algebraic set specified by linear matrix inequalities. Thus, the upper and the lower bounds of some moments can be computed by a semidefinite program. Using a protein dimerization process as an example, we demonstrate that the proposed method can precisely predict the mean and the variance of the copy number of the monomer protein.

description: We show that gravity and matter fields are generically entangled, as a consequence of the local Poincaré symmetry. First, we present a general argument, applicable to any particular theory of quantum gravity with matter, by performing the analysis in the abstract nonperturbative canonical framework, demonstrating the nonseparability of the scalar constraint, thus promoting the entangled states as the physical ones. Also, within the covariant framework, we show explicitly that the Hartle-Hawking state in the Regge model of quantum gravity is necessarily entangled. Our result is potentially relevant for the quantum-to-classical transition, taken within the framework of the decoherence programme: due to the gauge symmetry requirements, the matter does not decohere, it is by default decohered by gravity. Generically, entanglement is a consequence of interaction. This new entanglement could potentially, in form of an "effective interaction", bring about corrections to the weak equivalence principle, further confirming that spacetime as a smooth four-dimensional manifold is an emergent phenomenon. Finally, the existence of the gauge-protected entanglement between gravity and matter could be seen as a criterion for a plausible theory of quantum gravity, and in the case of perturbative quantisation approaches, a confirmation of the persistence of the manifestly broken gauge symmetry.

Characterisation of the Helix pomatia agglutinin binding glycoproteins of colorectal cancer cell lines and tissue samples
Creators: name: Saint-Guirons, Julien
Publisher: name: University of Westminster
Year: 2007

description: Colorectal cancer (CRC) is one of the most common malignancies in the US and Western Europe and metastatic dissemination after CRC is a leading cause of mortality. New markers predictive of cancer cell behaviour are actively sought both as targets and as a means of predicting patient prognosis. The lectin from the Roman snail Helix pomatia (HPA) has attracted interest as tool for the detection of metastatic colorectal cancer but the HPA binding partners have remained poorly characterised. We established an in vitro model using human colorectal cancer cell lines ranging from HPA negative, non metastatic, to HPA positive and metastatic. Confocal microscopy was used to assess the HPA binding pattern in the cell lines and the monosaccharides N-acetylgalactosamine, N-acetylglucosamine, and sialic acid were used to inhibit the interaction between the lectin and the cancer cells. A proteomic approach based on cell membrane isolation, pre-fractionation using lectin affinity chromatography, followed by 2-dimensional electrophoresis and MALDI-TOF-MS enabled the identification of the HPA binding proteins in the metastatic cancer cell line HT29. The proteins that eluted in the HPA binding fraction were present either by virtue of their ability to bind directly to HPA or as protein complexes of HPA binding partners and included molecules involved in cell adhesion / migration (integrin a6, integrin aV, annexins) re-modeling (filament proteins including oc tubulin, Ptubulin, cytokeratins, actin) and anti-apoptotic pathways (Hsp-70, Hsp-90, Hsp-96 and TNFR-1). Although many of these proteins have previously been described as altered in cancer, we are not aware of a single reagent like HPA which will concurrently bind all of these molecules.

description: Modified gravity theories can introduce modifications to the Poisson equation in the Newtonian limit. As a result, we expect to see interesting features of these modifications inside stellar objects. White dwarf stars are one of the most well studied stars in stellar astrophysics. We explore the effect of modified gravity theories inside white dwarfs. We derive the modified stellar structure equations and solve them to study the mass-radius relationships for various modified gravity theories. We also constrain the parameter space of these theories from observations.

Coding for Segmented Edit Channels

description: This paper considers insertion and deletion channels with the additional assumption that the channel input sequence is implicitly divided into segments such that at most one edit can occur within a segment. No segment markers are available in the received sequence. We propose code constructions for the segmented deletion, segmented insertion, and segmented insertion-deletion channels based on subsets of Varshamov-Tenengolts codes chosen with pre-determined prefixes and/or suffixes. The proposed codes, constructed for any finite alphabet, are zero-error and can be decoded segment-by-segment. We also derive an upper bound on the rate of any zero-error code for the segmented edit channel, in terms of the segment length. This upper bound shows that the rate scaling of the proposed codes as the segment length increases is the same as that of the maximal code.

description: Motivated by machine learning applications in networks of sensors, internet-of-things (IoT) devices, and autonomous agents, we propose techniques for distributed stochastic convex learning from high-rate data streams. The setup involves a network of nodes---each one of which has a stream of data arriving at a constant rate---that solve a stochastic convex optimization problem by collaborating with each other over rate-limited communication links. To this end, we present and analyze two algorithms---termed distributed stochastic approximation mirror descent (D-SAMD) and accelerated distributed stochastic approximation mirror descent (AD-SAMD)---that are based on two stochastic variants of mirror descent and in which nodes collaborate via approximate averaging of the local, noisy subgradients using distributed consensus. Our main contributions are (i) bounds on the convergence rates of D-SAMD and AD-SAMD in terms of the number of nodes, network topology, and ratio of the data streaming and communication rates, and (ii) sufficient conditions for order-optimum convergence of these algorithms. In particular, we show that for sufficiently well-connected networks, distributed learning schemes can obtain order-optimum convergence even if the communications rate is small. Further we find that the use of accelerated methods significantly enlarges the regime in which order-optimum convergence is achieved; this is in contrast to the centralized setting, where accelerated methods usually offer only a modest improvement. Finally, we demonstrate the effectiveness of the proposed algorithms using numerical experiments.

Scale Magnetic Effect in Quantum Electrodynamics and the Wigner-Weyl Formalism

description: The Scale Magnetic Effect (SME) is the generation of electric current due to conformal anomaly in external magnetic field in curved spacetime. The effect appears in a vacuum with electrically charged massless particles. Similarly to the Hall effect, the direction of the induced anomalous current is perpendicular to the direction of the external magnetic field $\bf B$ and to the gradient of the conformal factor $τ$, while the strength of the current is proportional to the beta function of the theory. In massive electrodynamics the SME remains valid, but the value of the induced current differs from the current generated in the system of massless fermions. In the present paper we use the Wigner--Weyl formalism to demonstrate that in accordance with the decoupling property of heavy fermions the corresponding anomalous conductivity vanishes in the large-mass limit with $m^2 \gg |e {\bf B}|$ and $m \gg |\nabla τ|$.

Superconducting proximity in three dimensional Dirac materials: odd-frequency, pseudoscalar, pseudovector and tensor-valued superconducting orders

description: We find that a conventional s-wave superconductor in proximity to three dimensional Dirac material (3DDM), to all orders of perturbation in tunneling, induces a combination of s and p-wave pairing only. We show that the Lorentz invariance of the superconducting pairing prevents the formation of Cooper pairs with higher orbital angular momenta in the 3DDM. This no-go theorem acquires stronger form when the probability of tunneling from the conventional superconductor to positive and negative energy states of 3DDM are equal. In this case all the p-wave contribution except for the lowest order, identically vanish and hence we obtain an exact result for the induced p-wave superconductivity in 3DDM. Fierz decomposing the superconducting matrix we find that temporal component of the vector superconducting order and spatial components of the pseudo-vector order are odd-frequency pairing. We find that the latter is odd with respect to exchange of position and chirality of the electrons in the Cooper pair and is spin-triplet which is necessary for NMR detection of such an exotic pseudo- vector pairing. Moreover, we show that the tensorial order breaks into a polar vector and an axial vector and both of them are conventional pairing except for being spin-triplet. According to our study, for gapless 3DDM the tensorial superconducting order will be the only order which is odd with respect to the chemical potential μ. Therefore we predict that a transverse p-n junction binds Majorana fermions. This effect can be used to control the neutral Majorana fermions with electric fields.

description: It was shown recently that, beside the traditional Liouville action, other functionals appear in the gravitational action of two-dimensional quantum gravity in the conformal gauge, the most important one being the Mabuchi functional. In a letter we proposed a minisuperspace action for this theory and used it to perform its canonical quantization. We found that the Hamiltonian of the Mabuchi theory is equal to the one of the Liouville theory and thus that the spectrum and correlation functions match in this approximation. In this paper we provide motivations to support our conjecture.

Powerful statistical inference for nested data using sufficient summary statistics

description: Hierarchically-organized data arise naturally in many psychology and neuroscience studies. As the standard assumption of independent and identically distributed samples does not hold for such data, two important problems are to accurately estimate group-level effect sizes, and to obtain powerful statistical tests against group-level null hypotheses. A common approach is to summarize subject-level data by a single quantity per subject, which is often the mean or the difference between class means, and treat these as samples in a group-level t-test. This 'naive' approach is, however, suboptimal in terms of statistical power, as it ignores information about the intra-subject variance. To address this issue, we review several approaches to deal with nested data, with a focus on methods that are easy to implement. With what we call the sufficient-summary-statistic approach, we highlight a computationally efficient technique that can improve statistical power by taking into account within-subject variances, and we provide step-by-step instructions on how to apply this approach to a number of frequently-used measures of effect size. The properties of the reviewed approaches and the potential benefits over a group-level t-test are quantitatively assessed on simulated data and demonstrated on EEG data from a simulated-driving experiment.
