description: We have studied the magnetic excitations of electron-doped Sr$_{2-x}$La$_x$IrO$_4$ ($0 \leq x \leq 0.10$) using resonant inelastic x-ray scattering (RIXS) at the Ir L$_3$-edge. The long range magnetic order is rapidly lost with increasing $x$, but two-dimensional short-range order (SRO) and dispersive magnon excitations with nearly undiminished spectral weight persist well into the metallic part of the phase diagram. The magnons in the SRO phase are heavily damped and exhibit anisotropic softening. Their dispersions are well described by a pseudospin-1/2 Heisenberg model with exchange interactions whose spatial range increases with doping. We also find a doping-independent high-energy magnetic continuum, which is not described by this model. The spin-orbit excitons arising from the pseudospin-3/2 manifold of the Ir ions broaden substantially in the SRO phase, but remain largely separated from the low-energy magnons. Pseudospin-1/2 models are therefore a good starting point for the theoretical description of the low-energy magnetic dynamics of doped iridates.

description: We report on observed differences between indoor and outdoor light induced degradation of a-Si:H
thin film modules. Since the performance of modules aged under outdoor conditions shows seasonal fluctuations, we
set up a conditioning procedure to remove such outdoor effects, and enable the comparison with indoor
measurements. Two examined modules with different degradation levels depending on outdoor light exposure history
showed similar degradation levels after conditioning. Additionally, these values were in good agreement with indoor
measurements.

description: Rezidivierte und refraktäre Hodentumoren waren bis zu Beginn der 80er Jahre nur selten kurativ behandelbar. Mit Einführung der Hochdosischemotherapie in Verbindung mit autologer Stammzellreinfusion, konnte eine kurative Behandlungsoption auch in dieser prognostisch ungünstigen Situation in der Klinik etabliert werden. Die vorliegende Arbeit beschreibt die Ergebnisse der ersten Phase I/II Studie zur klinischen Etablierung dieses Therapieverfahrens ebenso wie verschiedene nachfolgende Untersuchungen zur Optimierung der Hochdosischemotherapie. Eine "matched-pair" Analyse konnte zumindest im retrospektiven Vergleich, den Nutzen dieses neuen Therapieverfahrens im Vergleich zu einer konventionell-dosierten Behandlung belegen.
description: Until the beginning of the 1980ies relapsed and refractory germ-cell tumors were rarely cured. With the introduction of high-dose chemotherapy in combination with autologous stem cell reinfusion, a curative treatment option could be established in this prognostically unfavorable situation. The present work describes the results from the initial phase I/II studies that established this new treatment as well as the results of several subsequent trials to optimize this new procedure. Finally, the results of a "matched-pair" analysis is presented that demonstrates the superiority of this new treatment as compared to conventional-dose chemotherapy.

description: We revisit AdS$_2$ holography with the Sachdev-Ye-Kitaev models in mind. Our main result is to rewrite a generic theory of gravity near an AdS$_2$ throat as a novel hydrodynamics coupled to the correlation functions of a conformal quantum mechanics. This gives a prescription for the computation of $n$-point functions in the dual quantum mechanics. We thereby find that the dual is maximally chaotic.

description: We examine the cosmological sector of a gauge theory of gravity based on the SO(4,2) conformal group of Minkowski space. We allow for conventional matter coupled to the spacetime metric as well as matter coupled to the field that gauges special conformal transformations. An effective cosmological constant is generated dynamically via solution of the equations of motion, and this allows us to recover the late time acceleration of the universe. Furthermore, gravitational fields sourced by ordinary cosmological matter (i.e. dust and radiation) are significantly weakened in the very early universe, which has the effect of replacing the big bang with a big bounce. Finally, we find that this bounce is followed by a period of nearly-exponential slow roll inflation that can last long enough to explain the large scale homogeneity of the cosmic microwave background.

description: Mechanical stability of EWT solar cells deteriorates when holes are created in the wafer. Nevertheless,
the chemical etching after the hole generation process improves the mechanical strength by removing part of the
damage produced in the drilling process. Several sets of wafers with alkaline baths of different duration have been
prepared. The mechanical strength has been measured by the ring on ring bending test and the failure stresses have
been obtained through a FE simulation of the test. This paper shows the comparison of these groups of wafers in
order to obtain an optimum value of the decreased thickness produced by the chemical etching.

description: Die Aktivierung von Endothelzellen durch Bakterien und ihre Produkte trägt wesentlich zur Ausbildung klinischer Symptome in bakteriellen Infektionen bei. Die Freisetzung von Chemo- und Zytokinen führt im Konzert mit der Expression von Adhäsionsmolekülen durch das Endothel zur Rekrutierung und Aktivierung von Granulozyten. Zur Regulation der Entzündungsreaktion tragen parakrine und systemische Effekte, ausgelöst durch die Liberation von vasoaktiven Substanzen und Zytokinen durch Endothelzellen, bei. Der Zusammenbruch der endothelialen Barrierefunktion, gekennzeichnet durch den Verlust der Permselektivität der endothelialen Grenzschicht, verursacht Ödembildung. In dieser Arbeit wurde die molekulare Interaktion von Bakterien und ihren Produkten mit Endothelzellen untersucht. Effekte auf die Rekrutierung von Granulozyten und die endotheliale Barrierefunktion wurden charakterisiert. Dabei konnten aktivierte Signalwege identifiziert werden. Darauf basierend folgte die Entwicklung erster therapeutischer Ansätze. Zusammengefasst erbrachten diese experimentellen Untersuchungen neue Erkenntnisse zum Verständnis der Bakterien-Endothel Interaktion.
description: Activation of endothelial cells by bacteria and their products contributed significantly to clinical signs of bacterial infections. Liberation of chemo- and cytokines in concert with expression of adhesion molecules by the endothelium resulted in recruitment of granulocytes. Paracrine and systemic effects of vasoactive agents and cytokines secreted by endothelial cells contributed the regulation of inflammation. Loss of endothelial barrier function induced edema formation. This postdoctoral lecture qualification addressed the molecular interaction of bacteria and their products with endothelial cells. The recruitment of granulocytes, the regulation of endothelial barrier function and activated signalling pathways in endothelial cells were analyzed. Based on these experiments new therapeutic strategies have been tested. In summary, extended these experimental investigations the understanding of bacterial-endothelial interaction.

description: It has already been proven that Al2O3 can provide a high level of surface passivation for p and n-type
crystalline silicon (c-Si) [1-4]. The passivation mechanism is considered to be related to two components: low interfacial
trap density (Dit) and high amount of negative fixed charges (Qf), which induce a built-in electric field. In order to get
understanding on the electrical and process parameters which govern the passivation quality, a Corona charging tool was
employed. This technique enables to bring together spatially resolved information on charges and carrier lifetime.
Furthermore, the injection level can be tuned, which allows decoupling the bulk and surface contribution in the carrier
lifetime measurement. Two main process parameters: the Al2O3 thickness and the post deposition anneal were varied to
evaluate the sensitivity of the technique. The carrier lifetime information extracted from the “Quantox” shows to be
consistent with the one extracted by QSSPC-PL measurements. As a result, the “Quantox” tool appears to be an
appropriate tool for solar applications in order to study the quality of any passivation layers and Al 2O3 in particular.

description: What are the limits of automated Twitter sentiment classification? We analyze a large set of manually labeled tweets in different languages, use them as training data, and construct automated classification models. It turns out that the quality of classification models depends much more on the quality and size of training data than on the type of the model trained. Experimental results indicate that there is no statistically significant difference between the performance of the top classification models. We quantify the quality of training data by applying various annotator agreement measures, and identify the weakest points of different datasets. We show that the model performance approaches the inter-annotator agreement when the size of the training set is sufficiently large. However, it is crucial to regularly monitor the self- and inter-annotator agreements since this improves the training datasets and consequently the model performance. Finally, we show that there is strong evidence that humans perceive the sentiment classes (negative, neutral, and positive) as ordered.

description: In den letzten fünf Jahren gelang es, drei neue genetische Krankheitsbilder aus dem Kreis der pädiatrischen Endokrinologie klinisch zu beschreiben und deren genetische Grundlage aufzuklären. Hierbei waren vor allem die klinischen Erscheinungsbilder ungewöhnlicher Patienten, die neben bekannten hormonellen Ausfällen durch assoziierte Defekte auffielen, für die gezielte Suche nach genetischen Defekten ausschlaggebend. In allen drei Fällen konnten die assoziierten Symptome durch den primären genetischen Defekt molekular geklärt werden. Mittlerweile ist bei weiteren Patienten ein Mutationsnachweis gelungen und der zuerst von uns beschriebene Phänotyp konnte jeweils bestätigt werden. Bei den beschriebenen defekten handelt es sich um den POMC Gendefekt (klinisches Bild: Adipositas, rote Haarfarbe und Hypocortisolismus), den LHX3 gendefekt (klinisches Bild: Hypopituitarismus und Enschränkung der Haslrotation) und den NKX2.1 Gendefekt (klinisches Bild: Angeborene Hypothyreose und Choreoathetose).
description: In the last few years'' three new genetic syndromes were described which affect diseases within the field of paediatric endocrinology. The clinical picture of uncommon patients, which are affected beside known endocrine defects by additional associated symptoms, led to the molecular differential diagnosis which resulted in the description of new mutations. In all three cases the additional symptoms could be explained by the identified genetic defect. Meanwhile additional patients were identified with mutations in the affected genes, which confirmed the initial description of the new clinical diseases. The identified syndromes are: POMC gene defect (clinical picture: obesity, red hair, hypocortisolism), LHX3 gene defect (clinical picture: hypopituitarism and decreased neck movement) and NKX2.1 gene defect (clinical picture: congenital hypothyroidism and choreoathetosis).

description: We propose to reformulate the payoff matrix structure of Prisoner's Dilemma Game, by introducing threat and greed factors, and show their effect on the co-evolution of memory and cooperation. Our findings are as follows. (i) Memory protects cooperation. (ii) To our surprise, greater memory size is unfavorable to evolutionary success when there is no threat. In the absence of threat, subsequent generations lose their memory and are consequently invaded by defectors. (iii) In contrast, the presence of an appropriate level of threat triggers the emergence of a self-protection mechanism for cooperation, which manifests itself as an increase in memory size within subsequent generations. On the evolutionary level, memory size acts like an immune response of the generations against aggressive defection. (iv) Even more extreme threat results again in defection. Our findings boil down to the following: The dose of the threat makes the resistance for cooperation.

description: The present paper investigates the effect of shading experimentally and also through simulation. A PC
based test set up is designed, developed and fabricated to study shading effect on a module. The arrangement makes
use of PC controlled loading of solar module and scans through its V-I characteristics. The data acquisition card
acquires data of voltage, current, solar insolation and temperature using computer programs written in ‘C’ language.
The shading effect is produced by using opaque piece of cloth on a cell in the module and then plotting its I-V graph
using the experimental set up. The experimental result on the PV module is used to extract five model parameters of
the PV cells for simulation studies. A PSpice based simulation is carried out to study shading effect on I-V curves,
and multiple local maxima. Simulation studies also investigate variation in current and voltage at Maximum power
point with respect to varying shading factor. The effect of bypass diode on modules performance is also investigated.

description: Es werden verschiedene Aspekte interner magnetischer Hintergrundfelder in Theorien offener Strings diskutiert. Phaenomenologisch und konzeptionell interessante Eigenschaften solcher Vakua, die Brechung von Supersymmetrie, Eichsymmetrie und chiraler Symmetrie, werden auf ganz generische Weise behandelt. Dann wird eine Spezialisierung auf Typ I Modelle, kompaktifiziert auf Tori und Bahnfaltigkeiten, durchgefuehrt. Daraus wird eine Methode gewonnen zur Konstruktion von Typ I Vakua mit attraktiven effektiven Feldtheorien als Niederenergienaeherungen, sowohl supersymmetrische wie nicht supersymmetrische Modelle mit chiralen Fermionspektren und Eichgruppen aehnlich dem Standardmodell oder einer vereinheitlichenden Verallgemeinerung desselben. Die am weitesten entwickelten Beispiele kombinieren magnetische Felder mit NSNS B-Feldern auf Bahnfaltigkeiten. Zuletzt wird noch eine verwandte Klasse von Modellen besprochen, die zwar eher weniger vielversprechende phaenomenologische Perspektiven bietet, aber einige konzeptionelle Spezialitaeten aufweist. In diesen Kompaktifizierungen werden asymmetrische Rotationen geeicht, so dass D-branen mit unterschiedlichen Werten fuer die magnetischen Felder auf ihrem Weltvolumen identifiziert werden, womit die Unterscheidung von kommutativen und nicht kommutativen Geometrien verlorengeht.
description: We discuss various aspects of internal magnetic background fields in open string theories. Phenomenologically and conceptually interesting properties of such string theory backgrounds, supersymmetry and gauge symmetry breaking, chiral fermion spectra and noncommutativity of the internal compactification manifolds, are treated in a rather generic framework. We then specialize to type I compactifications on tori and toroidal orbifolds with magnetic fields on the internal space. This allows to develop a strategy for constructing type I vacua with attractive low energy field theories which may either be supersymmetric or not and contain chiral spectra and gauge groups close to the Standard Model or some grand unified generalization thereof. The most sophisticated version uses magnetic fields and NSNS B-fields on orbifold spaces giving rise to a plethora of promising examples for semi-realistic string compactifications. We finally also present a related class of asymmetric orbifolds of type I which are of little phenomenological interest but still display certain interesting features. The asymmetric rotations which are gauged in these models identify D-branes with different values for the magnetic field on their world volume, such that the distinction of commutative and noncommutative internal geometries is lost.

description: The lifetime of solar modules can be limited by the fatigue of the copper-ribbons. Every temperature
change induces thermo-mechanical stress between the module components due to different coefficients of thermal
expansion.
The purpose of this work is to estimate the stresses on the ribbons during the production process and to characterize
the device-related low-cycle fatigue behaviour in detail.
FEM simulations were used to evaluate strength and stresses in copper-ribbons used in photovoltaic modules.
Experiments were carried out to determine the mechanical properties and the fatigue behaviour of these copperribbons.
In the result of these investigations the parameters of material models for ANSYS-FEM-Software were
determined.

description: PV system designers need an estimation of the temperature at which a system will be operating in the
field, in order to evaluate the losses due to thermal effects. To that purpose the IEC Standards for qualification of
modules point out at the NOCT, the Nominal Operating Cell Temperature, as an useful parameter. Anyway NOCT
measurements require an accurate elaboration of data, since they are to be referred to quasi stationary conditions, and
sometimes the correct interpretation of some clauses of the Standards are not so easy. Because NOCT measurements
put severe restrictions on the specific mounting and measurement conditions some laboratories as the ESTER
laboratory of the University of Rome Tor Vergata measure instead the NOST, the Nominal Operating Specific
Temperature. So a better and a deeper understanding of what can be effectively used as the operating temperature is
highly required. The paper intends to present and compare results of NOCT and NOST measurements, obtained
respectively by two different laboratories located one, the ENEA laboratory, in the Southern Italy, near Naples, and
the other in Rome, in the Central part of Italy.
title: A Global Exploration Of Programme Theory Within Surf Therapy
Creators: name: Marshall, Jamie
Publisher: name: Edinburgh Napier University
Year: 2022

description: Mental health problems have been estimated as the biggest challenge facing global health in recent years (Vigo et al., 2016) and has been further exacerbated by the COVID-19 pandemic (Usher et al., 2020). One novel approach to addressing this mental health crisis is the emergent ‘surf therapy’ paradigm which combines surf instruction/surfing and structured individual and/or group activities to promote psychological and physical well-being (International Surf Therapy Organisation, 2019). While surf therapy has been associated with a positive impact on mental health across many populations, a recent scoping review prioritised empirical understanding of surf therapy programme theory as a key priority for future research (Benninger et al., 2020).

To address this knowledge gap, this programme of study conducted a qualitative investigation into surf therapy programme theory for a range of populations (military veterans in the USA, youth in post conflict Liberia, and youth at-risk-of or with mental health diagnosis in Australia). Findings from these studies had practical implications for optimisation of surf therapy delivery and were then compared to identify generalisable theoretical mediators. Physical and Emotional Safe Spaces, Positive Social Connections, Respite from Negative Emotions / Symptoms, and Transferable Mastery emerged in multiple studies. The consistent identification of the importance of safe spaces within intervention structures presents a learning of significance for mental health provision both for and out with the surf therapy paradigm. Alongside this the identification of the potential symptom reliving impact of ‘flow’ states (Csikszentmihalyi, 2002) as experienced within surf therapy provide a novel research priority for the future. Subsequently a Delphi style consultation with a different population (emergency service/healthcare workers in Scotland) built upon these findings to provide a framework for a novel surf therapy intervention with this population and an example of contextual adaption of theoretical mediators.

The findings from the current research programme have presented an original and significant contribution to knowledge around programme theory within surf therapy and mental health. Taken together, all these conclusions make significant contributions to surf therapy’s aim of becoming a trusted, prescribed, and standard means of care in supporting global mental health (International Surf Therapy Organisation, 2018).

description: We present an XMM-Newton X-ray observation of TRAPPIST-1, which is an ultracool dwarf star recently discovered to host three transiting and temperate Earth-sized planets. We find the star is a relatively strong and variable coronal X-ray source with an X-ray luminosity similar to that of the quiet Sun, despite its much lower bolometric luminosity. We find L_x/L_bol=2-4x10^-4, with the total XUV emission in the range L_xuv/L_bol=6-9x10^-4, and XUV irradiation of the planets that is many times stronger than experienced by the present-day Earth. Using a simple energy-limited model we show that the relatively close-in Earth-sized planets, which span the classical habitable zone of the star, are subject to sufficient X-ray and EUV irradiation to significantly alter their primary and any secondary atmospheres. Understanding whether this high-energy irradiation makes the planets more or less habitable is a complex question, but our measured fluxes will be an important input to the necessary models of atmospheric evolution.

description: Large area (1.4 m2) thin film photovoltaic modules require precise control of the deposition uniformity.
The efficiency of modules based on hydrogenated amorphous silicon (a-Si:H) and tandem modules based a-
Si:H/microcrystalline silicon (μc-Si:H) can be strongly enhanced by optimizing light trapping induced by the front
contact transparent conductive oxide (TCO). One of the most important parameters to quantify light trapping is the
TCO haze. In this work, we present a large area mapping haze measurement system and we show how to use such a
system for characterization and optimization of Zinc Oxide TCO front contacts produced by LPCVD (low pressure
chemical vapour deposition). Simulations are used to show the relation between TCO coating uniformity and module
performance.

Honokiol is a natural compound isolated from the Magnoliaceae family with potent anti-cancer effects. However, the exact molecular mechanisms underpinning the anti-cancer effects of honokiol remain poorly defined. This study demonstrated that honokiol reduced cell viability, affected metabolic activities, inhibited cellular migration, promoted apoptotic effects and induced morphological alterations in the highly metastatic melanoma cell line, A375. Comprehensive qRT-PCR and immunoblotting analyses indicated that honokiol upregulated the expression of kisspeptin (KISS1) and its receptor, KISS1R, suggesting that KISS1 / KISS1R signalling pathway might be one of the molecular mechanisms targeted by honokiol. This study further revealed that honokiol-mediated KISS1 / KISS1R signalling pathway downregulated VEGF-A and MMP-2 transcription, upregulated the mRNA expression of MMP-9 and TIMP-4, but not NF-κB. Furthermore, treatment with kisspeptin 10, with or without honokiol has been demonstrated to alter the mRNA expression of KISS1, KISS1R, MMP-9, MMP-2, TIMP-4 and VEGF-A, but not NF-κB. This study suggests that KISS1 / KISS1R signalling pathway may be involved in honokiol-modulated anti-metastatic effects in human A375 melanoma cells, and that honokiol could be considered as a natural agent against skin cancer.

description: A model of a universe without big bang singularity is presented, which displaysanearly inflationary period ending just before a phase transition to a deflationary epoch. The model produces enough heavy particles so as to reheat the universe at temperatures in the MeV regime. After the reheating, it smoothly matches the standard $Λ$CDM scenario.

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1569-1575
description: Guided by the interpretation of CELLO open circuit voltage measurements a model for calculating
local serial resistance maps Rser(x, y) from luminescence images is introduced which uses the Taylor series in linear
order of the extracted current starting from open circuit condition. This approach is in strong contrast to the model of
independent diodes frequently used for obtaining Rser(x, y) maps from luminescence data. An optimal mode when just
using two luminescence maps is introduced, together with two additional variants, one which just needs two pure
electroluminescence maps and one which is completely contactless. Especially the contactless "shaded
luminescence" mode has a high potential to be used as inline measurement technique. On several examples the
results of the three modes are compared. Limitations and possible improvements in data evaluation for the two
additional modes are discussed. For typical mc-Si solar cells all three modes give similar quantitative results.

description: We prove a weighted $L_p$-estimate for the stochastic convolution associated to the stochastic heat equation with zero Dirichlet boundary condition on a planar angular domain $\mathcal{D}_{κ_0}\subset\mathbb{R}^2$ with angle $κ_0\in(0,2π)$. Furthermore, we use this estimate to establish existence and uniqueness of a solution to the corresponding equation in suitable weighted $L_p$-Sobolev spaces. In order to capture the singular behaviour of the solution and its derivatives at the vertex, we use powers of the distance to the vertex as weight functions. The admissible range of weight parameters depends explicitly on the angle $κ_0$.
title: Hybridisation as an experiential phenomenon: A practice-based approach towards conceptualising musical hybridisation
Creators: name: Hind, James
Publisher: name: Edinburgh Napier University
Year: 2022

description: Hybridisation is a multifaceted term that appears across several sociocultural contexts, while common conceptualisations of musical hybridisation in scholarship tend to be positioned in genre studies. As a result of the perceived disjunctions of taxonomical framings of genre however, analytically satisfying definitions of musical hybridity are seldom offered and this clear gap in musicological, ethnomusicological, and cultural research is yet to be adequately explored by conventional theoretical research. This thesis therefore argues that a practice-based approach is more appropriate towards contextualising and understanding this phenomenon. In doing so, it problematises language and concepts, including genre, that fail to accurately describe such phenomena and move towards a more tangible definition of hybridity. This is approached through the creation of a genre-free framework for the creation and analysis of this phenomenon, establishing the musical hybrid as an experiential product, and musical hybridisation as a process that entangles various modalities (theorised in this thesis) of construction, expression, and experience. This framework informs and contextualises a portfolio of original Scottish Gaelic-language music that exploits these modalities, providing a practical contextualisation of the hybridisation framework through the analysis of the hybridisation process and hybrid product(s) of the compositional work. Consequently, this thesis offers knowledge in the form of the theoretical framework and the musical output of my practice.

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4323-4327
description: In our paper we will compare grid-connected PV systems with fossil fuel based electricity within
electricity infrastructures at Indonesian islands. Our approach is based on geographic mapping of the irradiance
potential (kWh/m2/year), electrification rates on islands (%), performance prediction of grid-connected PV systems
(kWh/kWp) and the CO2 reduction potential (g/kWh) of grid-connected PV systems in the Indonesian archipelago in
the year 2011. So far, extensive studies on grid-connected PV systems for island electrification in Indonesia are
lacking, and as such the results will be relevant for the realization of a pilot grid-connected photovoltaic system of
35kWp in Jayapura, situated in the Indonesian province of Papua, since in this province the electrical energy demand
is growing.
In this study we presented a method to determine the potential of grid connected PV in Indonesia. The total potential
is about 94 TWh/year and the required installed capacity is around 80 GWp, based on PV modules with an efficiency
of 15%. By using the full potential of grid connected PV 3.0 Mt CO2 emissions can be saved.

description: We present a computational study of the magnetic anisotropy energy for a given concentration of the Mn ions in the GaAs host, in the framework of the density functional theory. We focus on the influence of a different kind of strains on the uniaxial magnetic anisotropy constants $K_1$ and $K_2$, which reflect the magnetic anisotropy energy out- and in- (001) plane, respectively. We have shown that the general trends for the applied biaxial strain on anisotropy constants are consistent with the experimental data. We have predicted the critical strains, for which the magnetization vector changes its direction. Our results have shown that it is not possible to modify considerably the uniaxial magnetic anisotropy constants, exposing (Ga,Mn)As to hydrostatic pressure of a magnitude reasonable from experimental point of view.

description: This study evaluated the relationship between gender and sentencing severity for defendants convicted of violent crimes, victimless crimes, and theft crimes in Norfolk Circuit Court during 2001 and 2002. Based upon social control theories, the author hypothesized that women receive harsher penalties than men for violent crimes and victimless crimes, but that men receive harsher penalties for theft crimes. To test these hypotheses, the author relied, in part, upon data collected by the Norfolk Commonwealth Attorney's office on 3368 criminal cases filed in 2001 and concluded by May 22, 2002. After eliminating cases not pertinent to the study, the data set included 251 violent crimes, 261 victimless crimes, and 502 theft crimes. The author obtained sentence length and sentencing guideline information on these cases directly from the court files. Three different measures of sentence severity were used: sentence type, sentence length, and guideline compliance, with guideline compliance considered the most accurate measure because of the built-in controls for criminal history and offense severity. Age, race, method of adjudication, attorney type, and judge were the control variables. Using ANOVA, cross-tabulations, and multiple regression analysis, the results supported the hypothesis that women receive harsher punishment for victimless crimes, but did not support the other two hypotheses. Women, on average, received substantially shorter sentences than men convicted of violent crime, but the guideline compliance scores did not reveal any statistically significant difference in sentence severity for men and women convicted of violent crime. Men received longer jail sentences than women for theft crimes, but guideline compliance scores did not reveal a statistically significant difference in sentence severity between men and women except when controlled for race; then, women received harsher penalties than similarly situated men. Further research is recommended on the interaction between race and gender, and policy makers may need to revise guidelines to include relative culpability, parenting responsibility, and pregnancy, if these factors are deemed legitimate sentencing considerations.

description: Impurities in industrially produced large area thin film silicon solar modules can adversely affect module
performance, production yield and process stability. Secondary Ion Mass Spectrometry was used to quantitatively
measure the elemental impurity concentrations in hydrogenated amorphous silicon (a-Si:H) and in hydrogenated microcrystalline
silicon (μc-Si:H). In this study, we implanted the impurities C, O, N, F, Al, Cr, Fe, Zn, and Sn as well
as the dopants B and P. SIMS analyses are performed on a-Si:H and μc-Si:H samples to understand the effect of ion
yield change, therefore quantification, of these elements in a-Si:H and μc-Si:H.
Radiative natural SUSY spectrum from deflected AMSB scenario with messenger-matter interactions

description: A radiative natural SUSY spectrum are proposed in the deflected anomaly mediation scenario with general messenger-matter interactions. Due to the contributions from the new interactions, positive slepton masses as well as a large |A_t| term can naturally be obtained with either sign of deflection parameter and few messenger species (thus avoid the possible Landau pole problem). In this scenario, in contrast to the ordinary (radiative) natural SUSY scenario with under-abundance of dark matter (DM), the DM can be the mixed bino-higgsino and have the right relic density. The 125 GeV Higgs mass can also be easily obtained in our scenario. The majority of low EW fine tuning points can be covered by the XENON-1T direct detection experiments.
