Efficacy of the MMPI-A in detecting trauma among delinquent youth: cross-validation of the Trauma Scale for Juvenile Offenders (TSJO)

ABSTRACT The Minnesota Multiphasic Personality Inventory – Adolescent (MMPI-A) is a widely researched personality assessment in psychology. However, the utility of the MMPI-A for detecting trauma among juvenile offenders is limited. A 17-item measure – Trauma Scale for Juvenile Offenders (TSJO) was examined to evaluate the trauma detection accuracy of the MMPI-A among juvenile offenders and provide preliminary validation for the TSJO. To determine the diagnostic utility of MMPI-A clinical scales, mean comparisons were conducted and significant scales were retained in a hierarchical logistic regression. To examine the diagnostic accuracy of the TSJO, the total score was included in the hierarchical model. TSJO cross tabulations were computed for the cutoff score. Mean comparisons by trauma group revealed Pa, Pt, Sc, and Si clinical scale differences. Regression output indicated statistical accuracy, but with limited clinical utility. Results showed moderate trauma detection accuracy (63.4%) of the TSJO cutoff. Findings provide limited support for using MMPI-A clinical scales in isolation when evaluating juvenile offenders for trauma. However, results provide empirical support for the TSJO as a valid measure for detecting trauma for this population.
NOAA-20 VIIRS screen transmittance functions determined with both yaw maneuver and regular on-orbit data

The Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the NOAA-20 satellite regularly performs on-orbit radiometric calibration of its reflective solar bands (RSBs) through observations of an onboard sunlit solar diffuser (SD). The incident sunlight passes through an attenuation careen (the SD screen) and then scatters off the SD to provide a radiance source for the calibration. The on-orbit change of the SD bidirectional reflectance distribution function (BRDF), denoted as the H-factor, is determined by an onboard solar diffuser stability monitor (SDSM) whose eight SDSM detectors observe the sun through another attenuation screen (the SDSM screen) and the sunlit SD consecutively to measure the SD BRDF change. The products of the SD screen transmittance and the BRDF at the mission start for both the SDSM and RSBs and the SDSM screen transmittance were measured prelaunch. Large unrealistic undulations in the H-factor were seen when using the prelaunch screen transmittances. Shortly after the satellite launch, fifteen on-orbit yaw maneuvers were performed to further characterize the screens. Although significantly improved, the H-factor derived using the yaw maneuver data determined screens still has large unrealistic undulations, revealing that the solar azimuth angular step size of the yaw maneuvers is too large. In this paper, we add high quality regular on-orbit data to the yaw maneuver data to further improve the relative products and the relative SDSM screen transmittance. The H-factor time series derived from the newly determined screen transmittances is much smoother than that derived from using only the yaw maneuver data and thus improves considerably the radiometric calibration accuracy.
Algorithmic resistance: media practices and the politics of repair

ABSTRACT The article constitutes a critical intervention in the current, dramatic debate on the consequences of algorithms and automation for society. While most research has focused on negative outcomes, including ethical problems of machine bias and accountability, little has been said about the possibilities of users to resist algorithmic power. The article draws on Raymond Williams’ work on media as practice to advance a framework for studying algorithms with a focus on user agency. We illustrate this framework with the example of the media activist campaign World White Web by the Swedish artist and visual designer Johanna Burai. We suggest that user agency in relation to algorithms can emerge from alternative uses of platforms, in the aftermath of algorithmic logics, and give birth to complicit forms of resistance that work through ‘repair’ politics oriented towards correcting the work of algorithms. We conclude with a discussion of the ways in which the proposed framework helps us rethink debates on algorithmic power.

Este estudo se direciona a aplicacao de controle por busca extremal (ESC) em uma malha de controle externa a fim de realizar o rastreamento de ponto de maxima potencia (MPPT). Para o caso no qual medicoes de potencia nao estao disponiveis, um mecanismo para estimacao de torque ou potencia e proposto. Este algoritmo de otimizacao nao necessita qualquer tipo de medida ou estimacao da velocidade do vento nem de conhecimento previo acerca da curva de potencia da turbina. Na malha de controle interna, um controlador nao linear robusto tambem e projetado a fim de garantir rastreamento pratico global para a velocidade angular do rotor da turbina. A parte robusta do controlador, que mantem uma resposta transiente rapida, e baseada em controle por modos deslizantes mas apresenta um sinal de controle suavizado (SSC), evitando chatttering. Tal controlador fora previamente projetado para sistemas lineares com grau relativo arbitrario, este trabalho apresenta uma primeira generalizacao para classe de plantas nao-lineares representada pelos sistemas de conversao de energia eolica. Alem disso, o algoritmo de controle nao necessita de medidas de fluxos do estator ou de observadores desta variavel.

Modelling the Information-Psychological Impact in Social Networks

The paper considers the objects, subjects, purposes, tools, methods and implementation of information-psychological impact (IPI). It suggests a cellular automata model of the diffusion process of information-psychological impact in social networks, the hierarchy of the changes in the states of the subjects of information-psychological impact and the chart of transitions from state to state used in the cellular automaton algorithm. The suggested cellular automaton takes into account the effect of forgetting the information-psychological impact, as well as social and psychological parameters and probabilistic characteristics of the subjects of the social network. It therefore allows for the modelling of the diffusion of the information-psychological impact in the social network. The model can be used to determine the number of subjects affected by the information-psychological impact and the possibility of successful diffusion of the impact. The modelling of the suggested algorithm was performed. The results of the modelling are analysed in the paper.

The Effects of Entrepreneurship Education, Individual Environmental Factor and Individual Trait on University Student’s Career Decision Self-efficacy

The purpose of this study is to analyze the effects of entrepreneurship education and individual environmental factor on university student’s career decision self-efficacy. A total of 346 university students responded to the survey and the data was analyzed using SPSS 18.0. To test the hypotheses of this study, correlation analysis and regression analysis were conducted. The results of this study showed that entrepreneurship education, role model, family entrepreneurial experience and career preparation behavior were positively related to career decision self-efficacy. While gender were not positively related to career decision self-efficacy. This study reconfirms the importance and change of recognition of university entrepreneurship education for enhancing decision-making self-efficacy as well as the importance of career preparation behavior, role model and family entrepreneurial experience that have a significant effect on career decision of university students.
Analysis of Tilted Dipole Arrays: Impedance and Radiation Properties

In this article, we investigate the radiation and impedance properties of arrays of tilted dipoles. A spectral periodic method of moments (MoM) is developed for the analysis of infinite arrays with arbitrarily tilted dipole elements, in free space or with a backing reflector. With the aid of this analysis method, the radiation characteristics of arrays of stacked dipoles over a ground plane are studied, explaining the variation of the patterns as a function of the interelement distance and the angle of inclination of the elements. Finite linear arrays of tilted dipoles are also investigated, to assess the dependence of the array characteristics on the number of elements. The developed method can be used to design arrays with nonsymmetric radiation patterns for angular filtering or pattern shaping.
Gait and balance kinematic control for a humanoid robot based on dual quaternion algebra

Este trabalho apresenta uma nova metodologia baseada na algebra de quaternios duais (QDs) para obter o modelo cinematico de um robo humanoide e propoe uma estrategia de controle que satisfaz as restricoes cinematicas que garantem uma caminhada estavel. O metodo de modelagem apresentado consiste de tres etapas: modelagem dos membros do robo, modelagem do centro de massa e modelagem do comportamento cooperativo das pernas, utilizando o Espaco de Cooperacao Dual. As vantagens deste novo metodo de modelagem sao a sua compacidade e menor esforco computacional demandado para calcular o modelo, quando comparado com metodos baseados em matrizes de transformacao homogeneas (MTH), uma vez que os QDs tem apenas oito parâmetros, enquanto as MTHs tem doze, e tambem porque a multiplicacao de QDs e mais barata computacionalmente que a multiplicacao de MTHs. Alem disso, os seus coeficientes podem ser diretamente utilizados na lei de controle, ao contrario das MTHs. A estrategia de controle foi projetada utilizando a pseudoinversa da matriz Jacobiana, a qual representa a tarefa da caminhada, com um termo de feed-forward de velocidade, e uma tarefa adicional, projetada para manter os bracos proximos de uma configuracao desejada, foi incluida no espaco nulo desta matriz Jacobiana. O modelo obtido, bem como o controlador proposto, foram validados utilizando o software de simulacao de realidade virtual para sistemas roboticos V-REP. Foi verificado que os dados estimados utilizando o modelo e os valores medidos se aproximaram bastante, evidenciando que o metodo de modelagem e preciso e fornece informacoes confiaveis. Alem disso, o robo controlado pela estrategia proposta foi capaz de executar diferentes movimentos de caminhada com sucesso e foi capaz de manter o equilibrio ate mesmo quando os bracos estavam se movendo. Este trabalho e a primeira etapa do Projeto Popeye, cujo objetivo geral e construir uma plataforma de testes para um robo humanoide real. Como trabalhos futuros, propoe-se a implementacao dos metodos apresentados em um robo real; a reducao do tempo de resposta dos controladores das juntas atraves do ajuste de seus ganhos; a melhoria da estrategia de controle para garantir a rejeicao de perturbacoes e a implementacao dos metodos em uma linguagem de programacao que garanta um tempo de latencia menor.
Granular Evolving Min-Max Fuzzy Modeling

The paper addresses a novel evolving functional fuzzy modeling algorithm using hyper-boxes and min-max fuzzy granulation. Data space granulation is done as data are input, and undergoes never ending adaptation us-ing expansion and reduction operations to encompass new information. A fuzzy rule is assigned to each hyperbox using Gaussian membership functions in the rule antecedents, and aﬃne functions in the rule consequents. The algorithm is fast, simple, and interpretable. Computational evaluation using time series modeling and nonlinear system identiﬁcation experiments shows that the granular evolving min-max fuzzy modeling algorithm outperforms current state of the art evolving algorithms counterparts.
FFT BASED SPECTRAL EWALD METHODS AS AN ALTERNATIVE TO FAST MULTIPOLE METHODS

In this paper, we review a set of fast and spectrally accurate methods for rapid evaluation of three dimensional electrostatic and Stokes potentials. The algorithms use the so-called Ewald decomposition and are FFT-based, which makes them naturally most efficient for the triply periodic case. Two key ideas have allowed efficient extension of these Spectral Ewald (SE) methods to problems with periodicity in only one or two dimensions: an adaptive 3D FFT that apply different upsampling rates locally combined with a newmethod for FFT based solutions of free space harmonic and biharmonic problems. The latter approach is also used to extend to the free space case, with no periodicity. For the non-radial kernels of Stokes flow, the structure of their Fourier transform is exploited to extend the applicability from the radial harmonic and biharmonic kernels. Awindow function is convolvedwith the point charges to assign values on the FTT grid. Spectral accuracy is attained with a variable number of points in the support of the window function, tuning a shape parameter according to this choice. A new window function, recently introduced in the context of a non-uniform FFT algorithm, allows for further reduction in the computational time as compared to the truncated Gaussians previously used in the SE method.
Patient Adherence to Self‐Monitoring Recommendations Taught in Extended Phase I Cardiac Rehabilitation

Background: Patients in cardiac rehabilitation programs are taught to self‐monitor heart rate (HR), rate of perceived exertion (RPE), and signs and symptoms of cardiac distress when they are performing strenuous activities. These interventions are emphasized in phase I cardiac rehabilitation in an effort to decrease the work on the heart in order to minimize the patient's risk for further cardiac damage. The purpose of this study is to describe patients' knowledge of and adherence to self‐monitoring recommendations 1 month following completion of extended phase I cardiac rehabilitation. Method: Twenty‐eight subjects who completed an extended phase I cardiac rehabilitation program at a metropolitan inpatient rehabilitation facility in 2003 completed 2 questionnaires, 1 at discharge and another 1 month following discharge. The questionnaires were based on the health belief model and measured patient perceptions, knowledge, adherence, and factors that were associated with adhering or not adhering to the self‐monitoring recommendations. Results: At 1 month following discharge, none of the subjects participated in phase II cardiac rehabilitation and 92% indicated they participated in hard physical activities that increased their heart rate and breathing rate at least once per week. None of the subjects monitored RPE, 36% were adherent to monitoring HR, and 71 % were adherent to monitoring signs and symptoms of heart trouble during hard physical activity. Common factors that made it harder to self‐monitor were memory and confidence. Conclusion: Participants did not adhere to education regarding selfmonitoring of HR and RPE taught to them in the extended phase I cardiac rehabilitation program.
Class-E Isolated DC–DC Converter With High-Rate and Cost-Effective Bidirectional Data Channel

In this article, we propose a methodology to create a through-the-barrier bidirectional communication channel between the two sides of an isolated class-E resonant dc–dc converter. Our methodology is innovative since communication occurs through the same transformer used for energy transfer, and relies on connecting and disconnecting an auxiliary capacitance. By doing so, the converter switches between a faster and a slower response without any change in the clock controlling its activity. With this, it is possible to achieve a very high-rate bidirectional communication (up to 1 b per switching clock period) with virtually no limitations in the converter power with respect to a standard class-E implementation. Measurements performed on a prototype operating at 1 MHz and capable of delivering up to 1.2 W is presented as a proof-of-concept.
Sobre a expansividade da democracia: uma proposta de reinterpretação do minimalismo democrático

This bibliographic essay aims to reconsider the propositions of Joseph Schumpeter’s democratic minimalism and, through this exercise, to examine how its conceptual core is amplified in the effective funcioning of democracy. After a brief analysis of the schumpeterian minimalism, we present some criticisms that were directed to it from the 1960s onwards. Finally, based on O’Donnell, Saffon and Urbinati, we propose an extension of proceduralism so that it contemplates a normative dimension. This theoretical-conceptual discussion, however limited, is relevant today in the occasion of the challenges faced by social scientists to identify with scientific rigor which countries are indeed democratic – despite holding periodic elections.
Low Vision Accessibility in Structural Equation Modeling Software

The purpose of this review is to explore the low vision accessibility features of software packages commonly used for structural equation modeling (SEM). The benefits of including accessibility features can extend well beyond the scope of helping users with disabilities, such as making classroom demonstrations or figures easier to read. This review evaluates four different programs: Mplus, STATA, AMOS (and SPSS), and R (and RStudio). While most of these programs do provide some accessibility features that are helpful for low vision users, there are areas where all these programs could be improved.
Regional Differences in the Response of Rainfall to Convectively Coupled Kelvin Waves over Tropical Africa

The representation of convection remains one of the most important sources of bias in global models, and evaluation methods are needed that show that models provide the correct mean state and variability, both for the correct reasons. Here we develop a novel approach for evaluating rainfall variability due to convectively coupled Kelvin waves (CCKWs) in this region. A phase cycle was defined for the CCKW cycle in OLR and used to composite rainfall anomalies. We characterize the observed (TRMM) rainfall response to CCKWs over tropical Africa in April and evaluate the performance of regional climate model (RCM) simulations: a parameterized convection simulation (P25) and the first pan-Africa convection-permitting simulation (CP4). TRMM mean rainfall is enhanced and suppressed by CCKW activity, and the occurrence of extreme rainfall and dry days is coupled with CCKW activity. Focusing on regional differences, we show for the first time that there is a dipole between West Africa and the Gulf of Guinea involving onshore/offshore shifts in rainfall, and the transition to enhanced rainfall over west equatorial Africa occurs one phase before the transition over east equatorial Africa. The global model used to drive the RCMs simulated CCKWs with mean amplitudes of 75%–82% of observations. The RCMs simulated coherent responses to the CCKWs and captured the large-scale spatial patterns and phase relationships in rainfall although the simulated rainfall response is weaker than observations and there are regional biases that are bigger away from the equator. P25 produced a closer match to TRMM mean rainfall anomalies than CP4 although the response in dry days was more closely simulated by CP4.
