title: Ex-military Personnel in the Criminal Justice System: An exploration of the violence committed across the military life course and the role of alcohol within this violence.
Creators: name: Moorhead, J
Publisher: name: Liverpool John Moores University
Year: 2019

description: This research has qualitatively engaged with military veterans within the criminal justice system of England and Wales who have been convicted of alcohol related violent offences. Deviating from a quantitative approach most commonly employed within the extant veteran-offender literature and employing a qualitative methodology has provided veteran participants, in custody and subject to probation intervention, with an opportunity to narrate their own experiences and understandings around both violence and alcohol use, as well as how these two areas have intersected, across the military life course. Central to this thesis is that the commission of domestic violence was the most common form of violence committed by the military veteran offender post transition. In light of this, a model to effectively engage with this population was proposed, namely The Military Informed Nested Ecological Model (MINEM). Developed from the Nested Ecological model proposed by Dutton (2006), the MINEM represents an analytical tool to engage with the domestically violent military veteran. Ultimately, a need to engage with and account for a military history when working with the domestically violent veteran within the criminal justice system was highlighted. Such a focus provides an opportunity to garner a deeper understanding around the nuanced risk and needs associated with this population, set against more common understandings of domestic violence within a civilian population, ultimately with a view to more effectively facilitate their desistance journey.

description: When this document was initially conceived, the main foreseen contents were linked to the (potentially differentiated) emotional needs of women and men in automated vehicles. The research and work developed during the DIAMOND project has contributed to widen the scope of this report to other fields beyond that of the emotions. In this sense, such aspects as the unfairness and inequality present in current cars need to be highlighted in a work of these characteristics. In addition, as Connected Automated Vehicles (CAVs) are still a product that is under development, we have considered it interesting to mention tools and methodologies in the guidelines that could be used to gain more knowledge of the needs and requirements of potential CAV passengers, especially girls and women. By doing so, we wanted to provide useful information which could contribute to improving fairness and equality in autonomous vehicles based on human factors and participatory design. This report contains the complete contents of the guidelines entitled “Autonomous vehicles through gender perspective glasses. Designing a more inclusive and gender-fair autonomous car”. The structure of the guidelines is based on the following main blocks: Introduction and definitions Results and recommendations Although we are aware that the information presented in this report covers only a tiny albeit important part of all that is going on in the field of CAVs, our purpose is in any case multiple: Those familiar with the concepts of gender equality and fairness will be able to gain technical knowledge about CAVs, and to understand how their vision and knowledge is important to develop better vehicles. Those familiar with the automotive sector and those who are aware of all the challenging developments taking place in autonomous vehicles will benefit by its human-centered approach which stresses women’s needs and perceptions. Those absolutely new to either of the two fields will discover to what degree the development of the automotive sector means a breakthrough in terms of the traditional concept of a privately owned vehicle. They will also identify the potential of applying the concepts of equality and fairness to such a technological field.

description: Data and code for The Facebook Algorithm’s Active Role in Climate Advertisement Delivery

Climate advertising on social media can shape attitudes toward climate change. Delivery algorithms, as key actors in the climate communication ecosystem, determine ad audience selection and might introduce demographic bias. Here, we present a two-part study—an observational analysis (N=275,632) and a field experiment (M=650)—to investigate algorithmic bias in Facebook’s climate ad dissemination . Our findings suggest that the algorithm’s selection of ad audiences can be explained by factors such as ad content, as well as audience location (U.S. states), gender, and age group. Moreover, the cost effectiveness of contrarian ads appears linked with the conservative political alignment of a state, while the cost effectiveness of advocacy ads correlates with liberal political alignment, as well as higher population, and per-capita GDP; ad targeting strategies further modulate these effects. The skew in the distribution of climate ads across states, age groups, and genders, reinforces existing climate attitudes.

description: Abstract: "Atomic transactions have become a widely accepted mechanism for coping with failures and concurrency in reliable distributed systems. Much recent work has focused on concurrency control algorithms, in particular on techniques for exploiting type-specific properties of data objects to enhance concurrency. One class of concurrency control algorithms that appears particularly promising are "hybrid" schemes in which transactions are assigned timestamps as they commit. Although these algorithms have received extensive theoretical analysis, they have not been implemented because they require non-trivial systems support.In this paper, we describe the first implementation of transaction commit timestamps, as provided in Avalon/C++, a high-level language for reliable distributed computing. We focus on the run-time data structures and algorithms needed to achieve a practical implementation of transaction commit timestamps."

We also present analogous results for an SU(2) gauge theory.

description: The electronic band structure of correlated Ca3Ru2O7 featuring an antiferromagnetic as well as a structural transition has been determined theoretically at high temperatures, which has led to the understanding of the remarkable properties of Ca3Ru2O7 such as the bulk spin valve effects. However, its band structure and Fermi surface (FS) below the structural transition have not been resolved even though a FS consisting of electron pockets was found experimentally. Here we report magneto electrical transport and thermoelectric measurements with the electric current and temper- ature gradient directed along a and b axes of an untwined single crystal of Ca3Ru2O7 respectively. The thermopower obtained along the two crystal axes were found to show opposite signs at low temperatures, demonstrating the presence of both electron and hole pockets on the FS. In addition, how the FS evolves across T* = 30 K at which a distinct transition from coherent to incoherent behavior occurs was also inferred - the Hall and Nernst coefficient results suggest a temperature and momentum dependent partial gap opening in Ca3Ru2O7 below the structural transition, with a pos- sible Lifshitz transition occurring at T*. The experimental demonstration of a correlated semimetal ground state in Ca3Ru2O7 calls for further theoretical studies of this remarkable material.

description: The intermolecular potential energy surfaces (PESs) of Ne–CO complex have been constructed by using the CCSD(T)-F12a method with the aug-cc-pVQZ basis set. These PESs were subsequently applied to investigate the microwave and infrared spectra via bound state calculations. Firstly, compared to the available microwave data, the pure rotational transitions with K = 0 and J ≤ 4 for this complex can be well reproduced. Furthermore, a set of accurate spectroscopic parameters were deduced for the fundamental (vCO = 1) and overtone (vCO = 2) bands. The vibrational shift for the normal isotopologue (Ne–12C16O) was determined to be –0.0683 cm−1, which is in excellent agreement with the experimental observation of –0.0711 cm−1. Isotope effects were also investigated, and the determined rotational constants and vibrational shifts display a fairly good linear relationship, which is classified into two types according to the 12C and 13C in the CO monomer.

description: We develop the first general, algorithm-agnostic, solution quality guarantees for Nash equilibria and approximate self-trembling equilibria computed in imperfect-recall abstractions, when implemented in the original (perfect-recall) game. Our results are for a class of games that generalizes the only previously known class of imperfect-recall abstractions where any results had been obtained. Further, our analysis is tighter in two ways, each of which can lead to an exponential reduction in the solution quality error bound. We then show that for extensive-form games that satisfy certain properties, the problem of computing a bound-minimizing abstraction for a single level of the game reduces to a clustering problem, where the increase in our bound is the distance function. This reduction leads to the first imperfect-recall abstraction algorithm with solution quality bounds. We proceed to show a divide in the class of abstraction problems. If payoffs are at the same scale at all information sets considered for abstraction, the input forms a metric space, and this immediately yields a 2-approximation algorithm for abstraction. Conversely, if this condition is not satisfied, we show that the input does not form a metric space. Finally, we provide computational experiments to evaluate the practical usefulness of the abstraction techniques. They show that running counterfactual regret minimization on such abstractions leads to good strategies in the original games.

description: Motivated by a radically new peer review system that the National Science Foundation recently experimented with, we study peer review systems in which proposals are reviewed by PIs who have submitted proposals themselves. An (m, k)-selection mechanism asks each PI to review m proposals, and uses these reviews to select (at most) k proposals. We are interested in impartial mechanisms, which guarantee that the ratings given by a PI to others’ proposals do not affect the likelihood of the PI’s own proposal being selected. We design an impartial mechanism that selects a k-subset of proposals that is nearly as highly rated as the one selected by the non-impartial (abstract version of) the NSF pilot mechanism, even when the latter mechanism has the “unfair” advantage of eliciting honest reviews

description: This paper addresses the problem of sentence-level sentiment analysis. In recent years, Convolution and Recursive Neural Networks have been proven to be effective network architecture for sentence-level sentiment analysis. Nevertheless, each of them has their own potential drawbacks. For alleviating their weaknesses, we combined Convolution and Recursive Neural Networks into a new network architecture. In addition, we employed transfer learning from a large document-level labeled sentiment dataset to improve the word embedding in our models. The resulting models outperform all recent Convolution and Recursive Neural Networks. Beyond that, our models achieve comparable performance with state-of-the-art systems on Stanford Sentiment Treebank.

description: This study examines the use of cognitive control during second language (L2) processing by adult language learners. Although cognitive control has been acknowledged as an important component of language processing for years, its conception was as a top-down mechanism of inhibition. Our functional MRI study investigated the correlates of both top-down and bottom-up control as well as semantic decision-making in a group of Spanish learners who varied in proficiency. We observed that multivariate activity patterns were better classified in high proficiency learners during the semantic decision task in regions associated with both top-down and bottom-up control. Additionally, we found that connectivity between these control regions was more organised in high than in low proficiency learners. These findings provide support for the relevance of the distinction between top-down and bottom-up control to language learning. The implications of this distinction are discussed with respect to the current theories of L2 acquisition.

description: Feature representation and classification algorithm are two important aspects for the task of image classification. Previous studies focused on using color histogram and/or texture as the features for representing an image. Support vector machines (SVM) have been among the most successful classification algorithms for image classification. In this paper, we examine a new type of representational feature, namely the ‘bigram’ feature, which computes a distribution for pixel pairs. Unlike color histogram based features, which treats each pixel as independent from others, the ‘bigram’ feature scheme is able to take the correlations between pairs of pixels into account. In experiments over six different image categories, the ‘bigram’ feature scheme appeared to be a better representation for image classification and achieved a better classification accuracy than either color histogram features, texture features or color correlograms.
Self-force on an arbitrarily coupled scalar charge in cylindrical thin-shell spacetimes

description: We consider the arbitrarily coupled field and self-force of a static massless scalar charge in cylindrical spacetimes with one or two asymptotic regions, with the only matter content concentrated in a thin-shell characterized by the trace of the extrinsic curvature jump $κ$. The self-force is studied numerically and analytically in terms of the curvature coupling $ξ$. We found the critical values $ξ_c^{(n)} = n/ ( ρ(r_s)\,κ)$, with $n \in \mathbb{N}$ and $ρ(r_s)$ the metric's profile function at the position of the shell, for which the scalar field is divergent in the background configuration. The pathological behavior is removed by restricting the coupling to a domain of stability. The coupling has a significant influence over the self-force at the vicinities of the shell, and we identified $ξ=1/4$ as the value for which the scalar force changes sign at a neighborhood of $r_s$; if $κ(1-4ξ)>0$ the shell acts repulsively as an effective potential barrier, while if $κ(1-4ξ)<0$ it attracts the charge as a potential well. The sign of the asymptotic self-force only depends on whether there is an angle deficit or not on the external region where the charge is placed; conical asymptotics produce a leading attractive force, while Minkowski regions produce a repulsive asymptotic self-force.

«DID I FEEL MORE ITALIAN OR ENGLISH?». L’INSERTO ITALIANO NEI DIARI DI GUERRA DI IRIS ORIGO (1939-1944)

description: Angloamericana per nascita e italiana per scelta, Iris Cutting, diventata Origo dopo il matrimonio, è un esempio di intellettuale cosmopolita del secondo Novecento. La sua produzione letteraria ospita spesso tematiche e soggetti della sua patria adottiva e in questi casi la penna della Origo, senza abbandonare l’inglese, si intinge però in inchiostri italiani per puntellare la diegesi con inserti nella lingua seconda. In questo saggio si approfondisce la presenza dell’elemento italiano nei diari di guerra dell’autrice, nei quali lo scoppio della seconda guerra mondiale e il suo sviluppo in Italia sono indagati con l’occhio lucido della straniera e l’empatia di chi conosce e ama profondamente l’Italia e il suo popolo. “Did i feel more Italian or English?”. Italian inserts in Iris Origo’s war diaries (1939-1944) Anglo-American by birth and Italian by choice, Iris Cutting, who became Origo after her marriage, is an example of a cosmopolitan intellectual from the second half of the twentieth century. Her literary production often includes themes and subjects about her adoptive country and in these cases Origo's writing, without abandoning English, dips into Italian to support the diegesis with additions in the L2. This essay explores the presence of the Italian element in the author's war diaries, where the outbreak of World War II and its development in Italy are investigated with the lucid eye of a foreigner and the empathy of one who knew and deeply loved Italy and its people.

description: The stochastic matching problem deals with finding a maximum matching in a graph whose edges are unknown but can be accessed via queries. This is a special case of stochastic k-set packing, where the problem is to find a maximum packing of sets, each of which exists with some probability. In this paper, we provide edge and set query algorithms for these two problems, respectively, that provably achieve some fraction of the omniscient optimal solution. Our main theoretical result for the stochastic matching (i.e., 2-set packing) problem is the design of an adaptive algorithm that queries only a constant number of edges per vertex and achieves a (1-ε) fraction of the omniscient optimal solution, for an arbitrarily small ε > 0. Moreover, this adaptive algorithm performs the queries in only a constant number of rounds. We complement this result with a non-adaptive (i.e., one round of queries) algorithm that achieves a (0.5 - ε) fraction of the omniscient optimum. We also extend both our results to stochastic k-set packing by designing an adaptive algorithm that achieves a (2/k - ε) fraction of the omniscient optimal solution, again with only O(1) queries per element. This guarantee is close to the best known polynomial-time approximation ratio of 3/k+1 -ε for the deterministic k-set packing problem [Furer 2013]. We empirically explore the application of (adaptations of) these algorithms to the kidney exchange problem, where patients with end-stage renal failure swap willing but incompatible donors. We show on both generated data and on real data from the first 169 match runs of the UNOS nationwide kidney exchange that even a very small number of non-adaptive edge queries per vertex results in large gains in expected successful matches.

description: We propose a novel method to increase the probability of identifying impulsive astrophysical bursts of low-energy neutrinos. The proposed approach exploits the temporal structure differences between astrophysical bursts and background fluctuations and it allows us to pinpoint weak signals otherwise unlikely to be detected. With respect to previous search strategies, this method strongly reduces the misidentification probability, e.g. for Super Kamiokande this reduction is a factor of $\sim 9$ within a distance of $D\sim 200$ kpc without decreasing the detection efficiency. In addition, we extend the proposed method to a network of different detectors and we show that the Kamland $\&$ LVD background reduction is improved by a factor $\sim 20$ up to an horizon of $D\sim75$ kpc.

description: We present a relativistic model describing a thin disk system composed of two fluids. The system is surrounded by a halo in the presence of a non-trivial electromagnetic field. We show that the model is compatible with the variational multi-fluid thermodynamics formalism, allowing us to determine all the thermodynamic variables associated with the matter content of the disk. The asymptotic behaviour of these quantities indicates that the single fluid interpretation should be abandoned in favour of a two-fluid model.

description: We have studied the effects of quenched random disorder created by dispersed aerosil nanoparticle gels on the nematic to smectic-A (N-SmA) and smectic-A to reentrant nematic (SmA- RN) phase transitions of thermotropic liquid crystal mixtures of 6OCB (hexyloxycyanobiphenyl) and 8OCB (octyloxycyanobiphenyl). These effects are probed using high-resolution synchrotron x-ray diffraction techniques. We find that the reentrant characteristics of the system are largely unchanged by the presence of the aerosil gel network. By comparing measurements of the smectic static structure amplitude for this 8OCB-6OCB+aerosil system with those for butyloxybenzilidene-octylaniline (4O.8)+aerosil gels, we find that the short-range smectic order in the smectic-A phase is significantly weaker in the reentrant system. This result is consistent with the behavior seen in pure 8OCB-6OCB mixtures. The strength of the smectic ordering decreases progressively as the 6OCB concentration is increased. Detailed line shape analysis shows that the high- and low-temperature nematic phases (N and RN) are similar to each other.

description: O presente trabalho traduz resultados e reflexões da análise efectuada a uma amostra de 525 imagens extraídas de 7 manuais escolares da disciplina de Ciências da Natureza do 6º ano de escolaridade do Ensino Básico, utilizando uma metodologia de análise de imagens segundo a perspectiva de Kress e Leeuwen (1996), gramática do “design” visual, inserida no contexto da semiótica social, devotada esta a extrair significados que procuram expandir a mera consideração formal e morfológica das imagens e que podem ser pertinentes equacionar sob o ponto de vista da didáctica e tecnologia educativa. Procura-se estabelecer bases para compreender se existe correlação entre o maior ou menor sucesso de vendas das editoras de manuais escolares consideradas e determinadas características que essas mesmas imagens possuam. Os resultados da análise esclarecem que as editoras que mais vendem obtém, de um modo geral, melhores pontuações nas variáveis das imagens consideradas, face aos manuais menos vendidos. Palavras-chave: Manuais escolares, análise de imagens didácticas, semiótica social e gramática da comunicação visual.

description: Television news has been the predominant way of understanding the world around us, but individual news broadcasters can frame or mislead audience’s understanding about political and social issues. We aim to develop a computer system that can automatically identify highly biased television news, which may prompt audience to seek news stories from contrasting viewpoints. But can computers determine if news videos were produced by broadcasters holding differing ideological beliefs? We developed a method of identifying differing ideological perspectives based on a large-scale visual concept ontology, and the experimental results were promising.

A Review of Multiple Try MCMC algorithms for Signal Processing

Publisher: name: arXiv

Subjects: subject: Computation (stat.CO)

description: Many applications in signal processing require the estimation of some parameters of interest given a set of observed data. More specifically, Bayesian inference needs the computation of {\it a-posteriori} estimators which are often expressed as complicated multi-dimensional integrals. Unfortunately, analytical expressions for these estimators cannot be found in most real-world applications, and Monte Carlo methods are the only feasible approach. A very powerful class of Monte Carlo techniques is formed by the Markov Chain Monte Carlo (MCMC) algorithms. They generate a Markov chain such that its stationary distribution coincides with the target posterior density. In this work, we perform a thorough review of MCMC methods using multiple candidates in order to select the next state of the chain, at each iteration. With respect to the classical Metropolis-Hastings method, the use of multiple try techniques foster the exploration of the sample space. We present different Multiple Try Metropolis schemes, Ensemble MCMC methods, Particle Metropolis-Hastings algorithms and the Delayed Rejection Metropolis technique. We highlight limitations, benefits, connections and differences among the different methods, and compare them by numerical simulations.

Attraction controls the entropy of fluctuations in isosceles triangular networks

description: We study two-dimensional triangular-network models, which have degenerate ground states composed of straight or randomly-zigzagging stripes and thus sub-extensive residual entropy. We show that attraction is responsible for the inversion of the stable phase by changing the entropy of fluctuations around the ground-state configurations. By using a real-space shell-expansion method, we compute the exact expression of the entropy for harmonic interactions, while for repulsive harmonic interactions we obtain the entropy arising from a limited subset of the system by numerical integration. We compare these results with a three-dimensional triangular-network model, which shows the same attraction-mediated selection mechanism of the stable phase, and conclude that this effect is general with respect to the dimensionality of the system.
EFFECT OF COMMON MARKET FOR EAST AND SOUTHERN AFRICA FREE TRADE AGREEMENT ON DAIRY TRADE PERFORMANCE AND THE MALAWIAN ECONOMY
Creators: name: KADAM’MANJA, BLIGNAUT JOSHUA

Subjects: International Relations/Trade

description: This study analysed the factors influencing dairy imports by estimating the effect of the Common Market for East and Southern Africa Free Trade Agreement (COMESA FTA) on dairy trade performance and Malawian economy. The data were obtained from the COMESA and World Bank databases (1990-2029). The empirical analysis from autoregressive distributed lag (ARDL) bounds test and error correction model (ECM) provide evidence of the long-run (cointegration) and short-run relationships between dairy product imports and Comesa free trade agreement, exchange rate and relative prices. The Granger causality (GC) test results suggest a one-way causality running from Comesa free trade agreement and exchange rate to dairy product imports, respectively, and bi-directional causality between dairy product imports and relative price. The results also show that real income has a high and negative elasticity with respect to dairy imports in the short run. The Verdoorn approach was applied to analyse the COMESA FTA effect on dairy trade performance and Malawian economy by computing trade creation and diversion. The results show that free trade has potential to generate welfare gains of about US$0.29 million, and positive net trade effect of US$1.0 million and US$1.02 million in short and long runs, respectively. This suggests that Malawi has benefited from COMESA FTA. Trade complementary index (TCI) was estimated to assess the effectiveness and favourability of free trade. The large estimated TCI (0.944) suggests effective and favourable trade agreement. The policy recommendations drawn include: first, to invest in large- and small-scale dairy enterprises in all the regions of the country to increase milk production for domestic consumption, exports and incomes. Second, to negotiate with COMESA member countries to remove all non-tariff barriers to harness potential regional market opportunities to maintain gains from free trade.
Quantum Tomography of a system of three-level atoms

description: We analyze the possibility of tomographic reconstruction of a system of three-level atoms in both non-degenerate and degenerate cases. In the non-degenerate case (when both transitions can be accessed independently) a complete reconstruction is possible. In the degenerate case (when both transitions are excited simultaneously) the complete reconstruction is achievable only for a single atom in the Sigma configuration. For multiple Sigma atoms, or even a single atom in the Lambda configuration, only partial reconstruction is possible. Examples of one and two-atom cases are explicitly considered.

Three-dimensional vortex-bright solitons in a spin-orbit coupled spin-$1$ condensate

description: We demonstrate stable and metastable vortex-bright solitons in a three-dimensional spin-orbit-coupled three-component hyperfine spin-1 Bose-Einstein condensate (BEC) using numerical solution and variational approximation of a mean-field model. The spin-orbit coupling provides attraction to form vortex-bright solitons in both attractive and repulsive spinor BECs. The ground state of these vortex-bright solitons is axially symmetric for weak polar interaction. For a sufficiently strong ferromagnetic interaction, we observe the emergence of a fully asymmetric vortex-bright soliton as the ground state. We also numerically investigate moving solitons. The present mean-field model is not Galilean invariant, and we use a Galilean-transformed mean-field model for generating the moving solitons.

description: We are developing a classfier that can automatically identify a web video's ideological perspective on a political or social issue (e.g., pro-life or pro-choice on the abortion issue). The problem has received little attention, possibly due to inherent difficulties in content-based approaches. We propose to develop such a classfier based on the pattern of tags emerging from folksonomies. The experimental results are positive and encouraging.
