Modeling Ideological Salience and Framing in Polarized Online Groups with Graph Neural Networks and Structured Sparsity

The increasing polarization of online political discourse calls for computational tools that automatically detect and monitor ideological divides in social media. We introduce a minimally supervised method that leverages the network structure of online discussion forums, speciﬁcally Reddit, to detect polarized concepts. We model polarization along the dimensions of salience and framing, drawing upon insights from moral psychology. Our architecture combines graph neural networks with structured sparsity learning and results in representations for concepts and subreddits that capture temporal ideological dynamics such as right-wing and left-wing radicalization.
The relation between diaphragmatic mobility and spinal curvatures in patients with chronic obstructive pulmonary disease

| In the chronic obstructive pulmonary disease (COPD), patients may have reduced diaphragmatic mobility and a series of compensations in the thoracic spine, the scapular and pelvic girdles. However, the relation between diaphragmatic mobility and postural changes in these individuals’ vertebral column and pelvis is not clear. The aim of this study was to verify if there is a relation between diaphragmatic mobility and spinal curvatures in patients with COPD and in apparently healthy individuals. Were evaluated 22 patients with COPD and 22 apparently healthy individuals. The evaluations consisted of: anthropometry, spirometry, diaphragmatic mobility and postural evaluation. Four postural alterations were analyzed: cervical lordosis, thoracic kyphosis, lumbar lordosis, pelvic position. There was no statistically significant difference between the groups, in relation to the variables age, body Relação entre a mobilidade diafragmática e as curvaturas da coluna vertebral em pacientes com doença pulmonar obstrutiva crônica The relation between diaphragmatic mobility and spinal curvatures in patients with chronic obstructive pulmonary disease Relación entre la movilidad diafragmática y las curvaturas de la columna vertebral en los pacientes con la enfermedad pulmonar obstructiva crónica Márcia Aparecida Gonçalves1, Bruna Estima Leal1, Gabriella Da Cunha Viegas2, Mariana Nunes Lúcio2, Giovana Zarpellon Mazo3, Elaine Paulin4 Endereço para correspondência: Elaine Paulin – Departamento de Fisioterapia, Universidade do Estado de Santa Catarina (Udesc), Centro de Ciências da Saúde e do Esporte (Cefid) – Rua Pascoal Simone, 358, bairro Coqueiros – Florianópolis (SC), Brasil. – CEP: 88080-350 – E-mail: elaine.paulin@udesc.br – Fone: (48) 3664-8602 – Fonte de financiamento: próprio – Conflito de interesses: nada a declarar – Apresentação: 1 dez. 2016 – Aceito para publicação: 12 ago. 2017 – Aprovado pelo Comitê de Ética, Certificado de Apresentação para Apreciação Estética: 08857612.2. 0000.0118 (Udesc).

First Courses in Statistical Science: The Status of Educational Reform Efforts

Over the past twenty years much has been written about the introductory or service course in statistics. Historically, this course has been viewed as difficult and unpleasant by many students and frustrating and unrewarding to teach by many instructors. Dissatisfactions with the introductory course have led people to suggest new models for the course, to lead workshops to reexamine this course (Hogg 1992), and to offer recommendations for how the course should be changed (Cobb 1992). This paper presents the results of a survey of teachers of the first statistics course, to determine the impact of reform efforts on the teaching of statistics. Suggestions and guidelines for teaching these courses are offered, based on the results of the survey.
Benchmarking the Robustness of Protein Folding Neural Networks: A COVID-19 Case Study Using AlphaFold

Protein folding neural networks (PFNNs) such as AlphaFold predict remarkably 1 accurate structures of proteins compared to other approaches. However, the robust-2 ness of such networks has heretofore not been explored. This is particularly relevant 3 given the broad social implications of such technologies and the fact that biologi-4 cally small perturbations in the protein sequence do not generally lead to drastic 5 changes in the protein structure. In this paper, we demonstrate that AlphaFold does 6 not exhibit such robustness despite its high accuracy. This raises the challenge of 7 detecting and quantifying the extent to which these predicted protein structures 8 can be trusted. To measure the robustness of the predicted structures, we utilize ( i ) 9 the root-mean-square deviation (RMSD) and ( ii ) the Global Distance Test (GDT) 10 similarity measure between the predicted structure of the original sequence and 11 the structure of its adversarially perturbed version. Based on the well-established 12 BLOSUM62 sequence alignment scoring matrix, we generate adversarial protein 13 sequences and show that the RMSD between the predicted protein structure and 14 the structure of the original sequence are very
Translingual Neurostimulation (TLNS): A novel approach to neurorehabilitation

CN-NINM technology represents a synthesis of a new non-invasive brain stimulation technique with applications in physical medicine, cognitive, and affective neurosciences. Our new stimulation method appears promising for the treatment of a full spectrum of movement disorders, and for both attention and memory dysfunction associated with traumatic brain injury. The integrated CN-NINM therapy proposed here aims to restore function beyond traditionally expected limits by employing both newly developed therapeutic mechanisms for progressive physical and cognitive training - while simultaneously applying brain stimulation through a portable neurostimulation device PoNS™. Based on our previous research and recent pilot data, we believe a rigorous in-clinic CN-NINM training program, followed by regular at-home exercises that will also be performed with CN-NINM, will simultaneously enhance, accelerate, and extend recovery from multiple impairments (e.g. movement, vision, speech, memory, attention, and mood), based on divergent, but deeply interconnected neurophysiological mechanisms of neuroplasticity.

The sample consisted of 32 teachers from eight educational institutions selected as non-probabilistic for convenience considering the sample selection criteria. The study was carried out in three periods. First, a questionnaire of 18 questions was applied to teachers to determine the level of knowledge about preventive measures, main oral diseases, and dental development. Subsequently, the educational intervention was carried out, which consisted of didactic training with images and videos for teachers. Finally, the teachers were evaluated with the Professional dentist from Altiplano carrying out the career in the private sector (dental office).
Exploring the Integration of Handheld Device Applications in Teaching and Learning in Textiles, Clothing and Design Programmes in Universities in Zimbabwe

This study made use of a qualitative approach with an intrinsic case study to explore how handheld devices applications were integrated in teaching and learning in Textiles, Clothing and Design programmes. Participants of the study were purposively sampled from the Textiles and Clothing department at a selected university of Science and Technology in Zimbabwe comprising eight lecturers and thirty-two students. In-depth, focus group interviews and observations were used to gather data for the study. The findings of the study showed that participants were still at the stage of actively experimenting with very limited handheld device applications for the purposes of teaching and learning. Photoediters and digital cameras were the commonest applications used in most modules of the Textiles, Clothing and Design programmes. Though the photoediters and digital cameras were found to match the multimedia category of the Functionality framework, these were not fully utilised by students. It was recommended that there is need for the Textiles, Clothing and Design lecturers to provide opportunities for students to use a variety of applications on handheld devices for collaborative designing in practical modules of the programmes as these can encourage the development of critical skills necessary for creating innovative textiles and fashion designs.
Selection of Myrciaria dubia clones under conditions of the savanna/forest transition of Roraima through multivariate analysis

Camu-camu (Myrciaria dubia), a fruit from the Amazon region, has received attention due to its high content of antioxidant compounds such as ascorbic acid and polyphenols. This study’s objective was to select camu-camu clones according to their morphological characteristics using multivariate analyses. We evaluated 56 camu-camu clones distributed in three blocks with two plants per experimental plot. The variables measured were plant height (H), number of basal branches (NBB), number of terminal buds (NTB), basal stem diameter (BSD), chlorophylls a (Chl a) and b (Chl b), and total chlorophyll (Chl a + b). Principal component (PCA) and multivariate clustering analyses were performed using the average linkage mean and Mahalanobis distance algorithms. After 24 months, results showed that the characteristic that least contributed to clone selection was NBB. The plant height (H), number of terminal buds (NTB), basal stem diameter (BSD), chlorophylls a (Chl a) and b (Chl b), and total chlorophyll (Chl a + b) had the most positive contribution towards the initial selection of camu-camu clones at two years of age. The 22 camu-camu clones showed the highest rate of vegetative development or vegetative quality index (VQI) in the transitional savanna/forest area of the northern Amazon, Brazil, after two years of transplanting.
Perceptions of Moral Intensity and Professional Commitment Towards Intention to Whistleblowing: Empirical Evidence from Malaysian Public Sector Organisations*

The study’s goal is to look at the factors that influence people’s willingness to whistleblow in the Malaysian public sector by applying two elements from the Moral Intensity Theory: the magnitude of consequences and societal consensus with professional commitment as an additional variable. The cross-sectional study used primary data collection through questionnaires adopted from previous studies. The survey questionnaires were distributed to target respondents from 27 ministries in Malaysian public sectors selected based on their grade positions in the departments ranging from Grade 29 and above. The findings revealed that societal consensus and professional commitments significantly impact the intention to whistleblow. The findings imply that closed people’s opinions may have certain persuasive elements that influence the act of whistleblowing as a moral and ethical activity, thereby increasing their whistleblowing intention. The results also suggest that when individuals are more committed to their career and organization, they will act ethically and under the professional norm, hence, they will be inclined to whistleblow. On the other hand, the magnitude of consequences suggested an insignificant relationship with the intention to whistleblow. The results could facilitate the government in curbing the whistleblowing issue by defining its root before the implementation of necessary policies.
An Analysis of Product Quality, Variations, And Prices on Purchase Decisions Case Study of Suzuki Ertiga Car Dealer at PT. Trans Sumatera Agung, Medan City

Car brand in the automotive market in Indonesia currently comes from Europe and Asia. Examples of these brands are Mitsubishi, KIA, Honda, Daihatsu, Suzuki, Ford, Proton, and Toyota. One of the most sold car variants in Indonesia is the MPV (Multi-Purpose Vehicle) types control nearly 60% of the national automotive market share. This is inseparable from the perception of the price of this type of family car which is relatively affordable for the middle class in Indonesia. (This study focuses on testing the consumer buying decision model for Multi-Purpose Vehicle (MPV) cars. The research model involves three independent variables, namely product quality, product variety and price, and the dependent variable of purchasing decisions.
Impacts of Corporate Social Responsibility and Authenticity on Brand Loyalty: Evidence from the Chain Coffee Shop Industry in Vietnam*

This study examines the impact of CSR and its authenticity on customer loyalty through the brand image in the chain coffee shop industry. Using qualitative and quantitative methods, 601 survey questionnaires were distributed, of which 491 were analyzed. The results show that CSR has a positive impact on brand image and customer loyalty. In addition, authenticity does not moderate the impact of CSR on brand image and loyalty, as it is difficult for customers to verify the authenticity of CSR action programs. This study emphasizes the importance of CSR action programs and authenticity for businesses to sustainably enhance their distinctive brand image and customer loyalty. Therefore, for sustainable development in the future, managers of coffee shop chains need to focus on the following issues. First, the most important thing is the right awareness of businesses regarding CSR and CSR authenticity. Third, businesses should strengthen the transparency of CSR action programs in various media so that consumers can easily verify authenticity, to increase brand image and improve customer loyalty.
Potential of maize ( Zea mays L.) populations derived from commercial single-cross hybrids for extraction of partially inbred lines under different nitrogen availability

Extraction of inbred lines is a very important step in maize breeding since these lines will be used to obtain hybrids intended for the market. However, this expensive process, hinders genotype evaluation in contrasting environments, especially regarding nitrogen (N) content. This study aimed to evaluate the potential of maize populations for line extraction and select partially inbred lines under different soil nitrogen (N) availability. Five populations were evaluated regarding their potential for line extraction. Fifty-five S1 partially inbred lines were extracted from these populations. The top-cross method was used to evaluate lines by crossing them with two testers. Hybrids evaluation used 110 top-cross hybrids, five base populations, and six checks. Two trials were carried out in Dourados and Caarapó. One trial had adequate fertilization (high N) while the other was under stress condition (low N). Hybrid DKB 789 showed potential for extraction of partially inbred lines, aiming at selecting N use efficiency. Base population BP (07) was the most suitable for the extraction of partially inbred lines aiming at N use efficiency. Partially inbred lines BP (07) 13, BP (07) 14, and BP (07) 17 are the most suitable for the extraction of top-cross hybrids with high grain yield, efficiency, and responsiveness to N.
Decomposing Productivity Change in the Presence of Environmental Variables

This paper provides a decomposition of labor productivity growth into contributions associated with technical change, efficiency change, returns to scale, and environmental variables. The decomposition is based on parametric estimation of labor requirement functions. This approach is applied to a panel of Latin American distribution utilities between 1994 and 2001. The main results are a positive labor productivity growth averaging 7.5% per year, and that this is mainly due to a shift in the frontier.
A . Appendix A . 1 . Network architectures and training parameters

The structure of the U-Net embedding network used for each dataset is described using the buliding block shown in Figure 1. The number of ConvBlocks in the encoder/decoder part of U-Net is chosen such that the receptive field of features in the last encoder layer is equal to or slightly bigger than the input size. We used group normalization [14] for 3D and electron microscopy experiments and batch normalization for CVPPP and Cityscapes datasets [6]. In the tables describing the architecture: second number after the comma corresponds the number of output channels from each layer, Upsample denotes nearest-neighbor upsampling and Concat denotes channel-wise concatenation of the output for a given decoder layer with the output from the corresponding encoder layer. Unless otherwise specified, Adam optimizer [7] with an initial learning rate of 0.0002, weight decay 10−5, β1 = 0.9 and β2 = 0.999 was used for training. Learning rate was reduced by a factor of 0.2 when the validation loss stopped improving after a dataset-dependent number of iterations. Training was stopped when the learning rate dropped below 10−6 or maximum number of iterations was reached. In all our experiments we use 16-dimensional embedding space, i.e. the output from the U-Net after the last 1×1 convolution has 16 channels. Input images were globally normalized to zero mean and a standard deviation of one unless stated otherwise.
AN EXTENSION OF THE ITˆ O INTEGRAL

We introduce the concept of instant independence for certain anticipating stochastic processes and take the class of instantly independent stochastic processes as a counterpart of adapted stochastic processes for the Ito theory of stochastic integration. Then we define the stochastic integral of a stochastic process which is a linear combination of the products of instantly independent and adapted stochastic processes. The crucial idea is to use the right endpoints as the evaluation points for the instantly independent factors, while the left endpoints are used for the adapted factors. We prove a special case of Ito's formula for this new stochastic integral and present some examples of stochastic dierential equations.
GaN-Based RF Power Devices and Amplifiers

The rapid development of the RF power electronics requires the introduction of wide bandgap material due to its potential in high output power density, high operation voltage and high input impedance. GaN-based RF power devices have made substantial progresses in the last decade. This paper attempts to review the latest developments of the GaN HEMT technologies, including material growth, processing technologies, device epitaxial structures and MMIC designs, to achieve the state-of-the-art microwave and millimeter-wave performance. The reliability and manufacturing challenges are also discussed.
Foreign Institutional Investments (FIIs) and the Saudi Stock Market: What Drives Foreign Institutions to Invest?

This paper analyzes the drivers behind foreign institutional investments (FIIs) in the Saudi stock market and their impact on market stability from 2015 till 2019 using quarterly data. The results of OLS panel regression and ARCH/GARCH model support the feedback trading hypothesis and reveal a herding and momentum behavior of foreign institutions. Foreign institutions are attracted to invest in large Saudi firms with high liquidity. Interest rates, GDP growth and oil prices all have a negative and significant impact on FIIs. In contrast, inflation indicates economic growth and has a positive impact on FIIs. FIIs tend to stabilize market returns and predict future values.
Optogenetic stimulation of pre–Bötzinger complex reveals novel circuit interactions in swallowing–breathing coordination

Significance Swallowing is a vital behavior that must be coordinated with breathing. Both behaviors originate in the medulla, but the pathways responsible for their interactions have yet to be determined. It is hypothesized that inhibition from the medullary inspiratory driver, the pre–Bötzinger complex (preBötC), inhibits swallowing from occurring during times of inspiration. Using optogenetic stimulation of inhibitory and excitatory preBötC neurons, we provide evidence that the preBötC is involved in normal swallow production and coordination with breathing. We also suggest the preBötC is connected to the laryngeal motoneurons of the nucleus ambiguus (NA) and simulation of Dbx1 neurons delays laryngeal closure, disrupting the normal swallow sequence. This study explores neural pathways involved in swallowing–breathing coordination.
Students' overuse of proportionality on missing-value problems: how numbers may change solutions

Previous research has shown that when confronted with missingvalue word problems, primary school students strongly tend to use proportional solution approaches, even if these approaches are inappropriate. We investigated whether (besides the missingvalue formulation of word problems) the numbers appearing in word problems are part of the superficial cues that lead students to (over)use proportionality. A test containing proportional and nonproportional word problems was given to 508 4th, 5th, and 6th graders. Numbers in these problems were experimentally manipulated so that the internal and external ratios were either integer or not. For proportional problems, performances decreased as a result of noninteger ratios. For nonproportional problems, noninteger ratios led to a decrease in the overuse of proportionality; only in the case of additive nonproportional problems was this decrease accompanied by an increase in correct answers. This effect decreased from 4th grade to 6th grade. Implications of this study for research and practice are discussed.
