Joint Constellation Design for the Two-User Non-Coherent Multiple-Access Channel

We consider the joint constellation design problem for the two-user non-coherent multiple-access channel (MAC). Based on an analysis on the non-coherent maximum-likelihood (ML) detection error, we propose novel design criteria so as to minimize the error probability. Based on these criteria, we propose a simple and efficient construction consisting in partitioning a single-user constellation. Numerical results show that our proposed metrics are meaningful, and can be used as objectives to generate constellations through numerical optimization that perform better than other schemes for the same transmission rate and power.
Fatigue-Aware Ad Creative Selection.

In online display advertising, selecting the most effective ad creative (ad image) for each impression is a crucial task for DSPs (Demand-Side Platforms) to fulfill their goals (click-through rate, number of conversions, revenue, and brand improvement). As widely recognized in the marketing literature, the effect of ad creative changes with the number of repetitive ad exposures. In this study, we propose an efficient and easy-to-implement ad creative selection algorithm that explicitly considers user's psychological status when selecting ad creatives. The proposed system was deployed in a real-world production environment and tested against the baseline algorithms. The results show superiority of the proposed algorithm.
Identification of the partial differential equations governing microstructure evolution in materials: Inference over incomplete, sparse and spatially non-overlapping data

Pattern formation is a widely observed phenomenon in diverse fields including materials physics, developmental biology and ecology among many others. The physics underlying the patterns is specific to the mechanisms, and is encoded by partial differential equations (PDEs). With the aim of discovering hidden physics, we have previously presented a variational approach to identifying such systems of PDEs in the face of noisy data at varying fidelities (Computer Methods in Applied Mechanics and Engineering, 353:201-216, 2019). Here, we extend our methods to address the challenges presented by image data on microstructures in materials physics. PDEs are formally posed as initial and boundary value problems over combinations of time intervals and spatial domains whose evolution is either fixed or can be tracked. However, the vast majority of microscopy techniques for evolving microstructure in a given material system deliver micrographs of pattern evolution wherein the domain at one instant does not spatially overlap with that at another time. The temporal resolution can rarely capture the fastest time scales that dominate the early dynamics, and noise abounds. Finally data for evolution of the same phenomenon in a material system may well be obtained from different physical samples. Against this backdrop of spatially non-overlapping, sparse and multi-source data, we exploit the variational framework to make judicious choices of moments of fields and identify PDE operators from the dynamics. This step is preceded by an imposition of consistency to parsimoniously infer a minimal set of the spatial operators at steady state. The framework is demonstrated on synthetic data that reflects the characteristics of the experimental material microscopy images.
Statistical inference of the value function for reinforcement learning in infinite‐horizon settings

Reinforcement learning is a general technique that allows an agent to learn an optimal policy and interact with an environment in sequential decision‐making problems. The goodness of a policy is measured by its value function starting from some initial state. The focus of this paper was to construct confidence intervals (CIs) for a policy’s value in infinite horizon settings where the number of decision points diverges to infinity. We propose to model the action‐value state function (Q‐function) associated with a policy based on series/sieve method to derive its confidence interval. When the target policy depends on the observed data as well, we propose a SequentiAl Value Evaluation (SAVE) method to recursively update the estimated policy and its value estimator. As long as either the number of trajectories or the number of decision points diverges to infinity, we show that the proposed CI achieves nominal coverage even in cases where the optimal policy is not unique. Simulation studies are conducted to back up our theoretical findings. We apply the proposed method to a dataset from mobile health studies and find that reinforcement learning algorithms could help improve patient’s health status. A Python implementation of the proposed procedure is available at https://github.com/shengzhang37/SAVE.
ImagineNet: Restyling Apps Using Neural Style Transfer

This paper presents ImagineNet, a tool that uses a novel neural style transfer model to enable end-users and app developers to restyle GUIs using an image of their choice. Former neural style transfer techniques are inadequate for this application because they produce GUIs that are illegible and hence nonfunctional. We propose a neural solution by adding a new loss term to the original formulation, which minimizes the squared error in the uncentered cross-covariance of features from different levels in a CNN between the style and output images. ImagineNet retains the details of GUIs, while transferring the colors and textures of the art. We presented GUIs restyled with ImagineNet as well as other style transfer techniques to 50 evaluators and all preferred those of ImagineNet. We show how ImagineNet can be used to restyle (1) the graphical assets of an app, (2) an app with user-supplied content, and (3) an app with dynamically generated GUIs.
Detection of very-high-energy gamma-ray transients with monitoring facilities

The study of the sky in Very High Energy gamma rays (VHE, E > 100 GeV) has led to the identification of a wealth of processes that are responsible for the acceleration of particles at the highest observed energies within the Milky Way and beyond. Observations with VHE facilities, like the Cherenkov Telescope Array (CTA), will be fundamental to investigate the characteristics of these processes. Still, the transient and unpredictable nature of the most powerful sources requires that effective monitoring strategies should be adopted to track them. With this study, we focus on the type of VHE transients that can be effectively detected with monitoring facilities. Using the data collected by Fermi-LAT during its observing campaign, we investigate the frequency, luminosity and timescales of different VHE transients, focusing on blazar flares and Gamma-Ray Bursts. We compare their properties with the performance of existing and future instruments. We show that pursuing an enhanced spectral coverage in the sub-TeV range with a large field-of-view instrument, operating in the Southern hemisphere, will effectively contribute to the investigation of different types of transients, both by providing prompt alerts to activate follow-up observations of the most energetic events, as well as by collecting critical information on their temporal and spectral evolution.
Reluctant additive modeling

Sparse generalized additive models (GAMs) are an extension of sparse generalized linear models which allow a model’s prediction to vary non-linearly with an input variable. This enables the data analyst build more accurate models, especially when the linearity assumption is known to be a poor approximation of reality. Motivated by reluctant interaction modeling (Yu et al. 2019), we propose a multi-stage algorithm, called reluctant additive modeling (RAM) , that can ﬁt sparse generalized additive models at scale. It is guided by the principle that, if all else is equal, one should prefer a linear feature over a non-linear feature. Unlike existing methods for sparse GAMs, RAM can be extended easily to binary, count and survival data. We demonstrate the method’s eﬀectiveness on real and simulated examples.

The Disposition Effect and Risk Preference in Losses

— We examine whether the risk preference in losses increase the disposition effect. We take 9526 investors’ annual trading data of a large china’s futures company in 2013 as an example. The results show that most of investors have disposition effect, only the professional investors have a moderate risk preference in loss do not have. Risk preference is an important factor, it increase the hold losses significantly, then the disposition effect increased. Moreover, the disposition effect has a negative impact on investment returns. the higher risk preference is, the more hold losses and cash profit is, but the return determined by hold losses.
Exploring the determinants of intention to use self-checkout systems in super market chain and its application

Article history: Received: September 21 2019 Received in revised format: October 28 2019 Accepted: November 3, 2019 Available online: November 7, 2019 Technology and innovativeness have played an important role in service industries because of the competitive state, especially in developing countries. While using innovative technologies such as self-checkouts in stores is seen as advantageous in many aspects for retailers, if customers cannot adopt it, the usage of in stores becomes disadvantageous. However, the literature offers limited knowledge about the customers' adoption of self-checkouts in spite of its value for the survival of firms. Therefore, understanding what factors affect individuals' intention to use self-checkout systems has been a need for both practitioners and researchers. This study aims to spot out the determinants of intention to use self-checkout systems in a supermarket chain. In this regard, this study employs the technology acceptance model (TAM) to which the constructs technology anxiety, technology self-efficacy, compatibility, and knowledge are incorporated into the original model. The results of the analysis of the data (N=281) reveals that: (i) technology self-efficacy and knowledge are positively related to two beliefs, perceived ease of use and perceived usefulness, (ii) compatibility is positively associated with perceived usefulness, (iii) perceived usefulness is positively related to attitude, and (iv) attitude is positively associated with intention to use. © 2020 by the authors; licensee Growing Science, Canada
Job Satisfaction Survey: A Confirmatory Factorial Analysis Based on Vocational Colleges Teachers Sample

This study was carried out to verify the measurement model of the construct of job satisfaction among technical teachers in Technical Vocational College Ministry of Education. A study involving 493 samples from 25 vocational colleges and comprising technical teachers in electrical and electronics engineering, civil engineering and mechanical engineering. The Structural Equation Modelling (SEM) approach with AMOS 20 software has been applied in this study. The original item was the adaptation of the Job Satisfaction Survey (JSS) questionnaire developed by Spector (1997), there were 32 items, after exploratory factor analysis was carried out 32 original items had decreased to 22 items, sub construct was also changed from 8 sub constructs to 4 sub construct only. To ensure that the job satisfaction measurement model can be verified, three factors have been evaluated, unidimensional, validity and reliability. After 10 items were dropped out, the data were re-analysed and the findings showed that all 22 items in the measurement model had factor loading meet the required level, all AVE values also meet the required level. While fitness indexes for Absolute Fit, Incremental Fit and Parsimonious Fit all meet the requirements set for all CR values = 0.6. Overall, it can be concluded that after the measurement model was modified by dropping 3 items with factor loading <0.6 then the model was fit to be used for structural model analysis process.
Lecturer Formative Feedback Preferences: The Influence of Disciplines

This study attempts to determine the choice of the feedback model related to discipline categorised as hard-applied, soft-applied, hard-pure and soft-pure. It also attempts to explore the extent in which the lecturers practise socio-constructivist feedback. It was a non-experimental study conducted in an offshore campus in Malaysia of an established Australian university. The data were collected by six research assistants through semi-structured interviews involving 31 lecturers from all the seven Schools in the university. The data were transcribed and analysed using the framework method as a form of thematic analysis. Since it was a deductive study, academic disciplines were used as pre-selected themes and in each feedback category, there were pre-defined codes. The results reveal that there is no serious evidence to link discipline to the choice of feedback model. In addition, lecturers do practise socio-constructivist feedback as well as other variants of feedback.
Global Positioning System Monitoring of High-Risk Sex Offenders: Implementation Challenges and Lessons Learned

Agencies incorporating new technology inevitably face challenges in the implementation process. In response to the passage of Proposition 83, which mandated lifelong supervision of people convicted of sex offenses in California, San Diego County initiated a pilot program assessing Global Positioning System (GPS) monitoring of such offenders considered high risk for reoffending. Using interviews of parole agents and administrators, parole agent records of supervision, and GPS monitoring data, we assess the challenges and lessons learned from the program which help inform the current policy context of electronic monitoring. Results show that rigorous GPS supervision involves substantial workload and resource increases for parole agencies, and may not be appropriate for all individuals convicted of sex offenses. The ethical and legal challenges of electronic monitoring, more generally, require further attention. The future of GPS monitoring will depend on how programs are implemented and resources are managed, as well as how ethical issues are addressed.

Defining Arabism: the Contestation of Arab Identity in the Hadrami Community in Betawi

This study of defining Arabism aims to analyze Arab identity in the hadrami community in Betawi. Arab identity in the hadrami community in Betawi could be seen in the use of the marriage title, and their respect for the ‘alawiyyin community. The hadrami community in Betawi made religion a distinctive feature of Arab identity, thus causing conflict between the hadrami community in defining Arabism. The problem in this study is events that occurred in the past, thus materials such as archives, books, journals, and newspapers related to the theme were used as sources in this study. The analysis of this study uses the hermeneutic phenomenology method in order to obtain a reconstruction of the history of Arabism that is close to the truth. This study provides the conclusion that identity is a source of conflict, resulting contestation in the hadrami community in Betawi. Kajian tentang mendefinisikan arabisme ini bertujuan untuk menganalisis identitas Arab pada komunitas hadrami di Betawi. Identitas Arab pada komunitas hadrami di Betawi dapat dilihat pada pemakaian gelar pernikahan, dan penghormatan mereka terhadap kelompok ‘alawiyyin. Komunitas hadrami di Betawi menjadikan agama sebagai bahan dari identitas Arab, sehingga menyebabkan konflik diantara komunitas hadrami untuk mendefinisikan arabisme pada identitas Arab tersebut. Masalah pada penelitian ini adalah segala peristiwa yang telah terjadi di masa lampau, maka bahan-bahan seperti arsip, buku, jurnal, dan surat kabar yang terkait dengan tema digunakan sebagai sumber dalam penelitian ini.

A longitudinal investigation of television viewing in adolescence and sexual perfectionism and satisfaction in adulthood

ABSTRACT This study examines associations between adolescents’ exposure to two television genres that convey contradictory sexual messages and the expectation of sexual perfectionism over a period of 15 years (N = 161). All respondents were in a romantic relationship in the final wave of this longitudinal study. Sitcom viewing during adolescence was related to more sexual perfectionism in adulthood, whereas youth drama viewing predicted less sexual perfectionism over the same period of more than a decade. These associations were not moderated by their motivation to learn about dating from television. Adolescents’ sitcom viewing was indirectly related to lower levels of sexual and relational satisfaction in young adulthood, whereas youth drama viewing indirectly predicted more satisfaction through the association with sexual perfectionism.
Depression and Reasons for Living Among AIDS Patients

by ABBY L. MARQUART The current study examined emotional distress, quality of life, physical health, and reasons for living in AIDS patients. Analyses revealed that emotional distress was associated with negative cognitive schemas related to the medical illness but not with physical functioning or role limitations. Importance attached to reasons for living reported by AIDS patients was best understood by overall quality of life. Reasons for living were not related to physical functioning. Results suggest that AIDS patients with poor physical functioning may maintain important reasons for living if a high sense of quality of life is achieved. Implications for improved assessment and treatment of quality of life in AIDS patients include treatment strategies that foster a sense of achievement, strengthen interpersonal relationships, and increase positive self-expression.
