PSYCHOLOGY OF EDUCATION

Adverse childhood experiences (ACEs) are distressful and potentially traumatic events during childhood. The goal of this research was to examine a link between the ACEs and college achievement (i.e., the average college grade, GPA). Given the robust link between the ACEs and depressiveness, and a negative impact that depression can have on academic achievement, we explored a mediating role of depressiveness scores between the ACEs and the GPA. The sample comprised 142 undergraduate college students. On a bivariate level, the ACE score correlated with depressiveness, but neither ACEs nor depressiveness scores correlated significantly with the GPA. However, when entered together in a mediation analysis, it was established that higher ACEs predict higher depressiveness, which, in turn, predicts lower GPA. At the same time, there is a direct portion of the effect, which suggests that higher ACEs predict higher GPA when depressiveness is accounted for. Thus, even though a total direct effect of the ACEs on the GPA is not significant, the results imply that this might be due to the ACEs having both negative and positive conditional effects on the GPA. We suggest that future research should examine the mechanisms by which overcoming adversity can have a positive impact on higher education achievements, likely through coping and resilience.
Analysis Of Out-Of-Plane Performance Of Composite Slab With Precast Concrete Ribbed Panels Under a Hanging Load

When studying the out-of-plane performance of a composite slab, distributing the load on the top slab surface may overestimate the integrity of the combined interface and result in unsafe shear capacity because the load path is from the top surface to the bottom of the slab. It is dif cult to observe cracking and crack distribution on the top surface of the slab during load application. In this paper, a static hanging load test of a two-span, two-way composite slab with precast concrete ribbed panels (CSPRP) was conducted. The hanging loading conditions were achieved by constructing loading frames and connecting the frames to a series of inverted U-shaped cables, which were suspended from the ribs of the precast concrete ribbed panels. After the cast-in-place concrete topping achieved its design strength, concrete blocks were placed in the loading frame to load the CSPRP. A comparative test of a two-span, two-way cast-in-place concrete slab was conducted at the same time, under the same conditions. The results showed that CSPRPs and castin-place concrete slabs exhibited comparable performance. The stiffness and crack resistance of CSPRPs were similar to those of cast-in-place concrete slabs. The mechanical properties of the combined interface of the CSPRP was compared with a common atplate composite slab. The results showed that the shear behavior on the combined interface of CSPRPs meets the shear strength requirements under serviceable working conditions better than common at-plate composite slabs. The combined interface of CSPRPs will not disengage under service loads.

Matching human vocal imitations to birdsong: An exploratory analysis

We explore computational strategies for matching human vocal imitations of birdsong to actual birdsong recordings. We recorded human vocal imitations of birdsong and subsequently analysed these data using three categories of audio features for matching imitations to original birdsong: spectral, temporal, and spectrotemporal. These exploratory analyses suggest that spectral features can help distinguish imitation strategies (e.g. whistling vs. singing) but are insufficient for distinguishing species. Similarly, whereas temporal features are correlated between human imitations and natural birdsong, they are also insufficient. Spectrotemporal features showed the greatest promise, in particular when used to extract a representation of the pitch contour of birdsong and human imitations. This finding suggests a link between the task of matching human imitations to birdsong to retrieval tasks in the music domain such as query-by-humming and cover song retrieval; we borrow from such existing methodologies to outline directions for future research.
Matching embeddings for Semi-supervised Domain Adaptation

In this work we address the problem of transferring knowledge obtained from a vast annotated source domain to a low labeled or unlabeled target domain. We propose Adversarial Variational Domain Adaptation (AVDA), a semi-supervised domain adaptation method based on deep variational embedded representations. We use approximate inference and adversarial methods to map samples from source and target domains into an aligned semantic embedding. We show that on a semi-supervised few-shot scenario, our approach can be used to obtain a signiﬁcant speed-up in performance when using an increasing number of labels on the target domain.
ECONOMIC COMPLEXITY TO ADDRESS CURRENT CHALLENGES IN INNOVATION SYSTEMS A NOVEL EMPIRICAL STRATEGY LINKED TO THE TERRITORIAL DIMENSION

In this framework, techniques inspired by complex systems analysis and network theory allow to measure the intangible capabilities necessary for a country or region to be competitive, both in absolute terms and in specific markets. This document addresses how different clogs of the innovation system co-evolve under complexity: both in terms of the different aspects (innovation, production, scientific activities) and geographical scales (countries, regions, cities).
Global existence of solutions to coupled PT -symmetric nonlinear Schrödinger equations

We study a system of two coupled nonlinear Schrödinger equations, where one equation includes gain and the other one includes losses. Strengths of the gain and the loss are equal, i.e., the resulting system is parity-time (PT ) symmetric. The model includes both linear and nonlinear couplings, such that when all nonlinear coefficients are equal, the system represents the PT -generalization of the Manakov model. In the one-dimensional case, we prove the existence of a global solution to the Cauchy problem in energy space H, such that the H-norm of the global solution may grow in time. In the Manakov case, we show analytically that the L-norm of the global solution is bounded for all times and numerically that the H-norm is also bounded. In the two-dimensional case, we obtain a constraint on the L-norm of the initial data that ensures the existence of a global solution in the energy space H.
Performance study of passive acoustic systems for detecting North Atlantic right whales in seaways: the Honguedo strait in the Gulf of St. Lawrence

Gervaise, C. , Simard, Y. , Aulanier, F. , and Roy, N. 2019. Performance study of passive acoustic systems for detecting North Atlantic right whales in seaways: the Honguedo strait in the Gulf of St. Lawrence. Can. Tech. Rep. Fish. Aquat. Sci. 3346: ix + 53 pp. This report addresses the problem of detecting and localizing whales located in a noisy seaway with passive acoustic monitoring (PAM) systems reporting the detections in real time. This general problem is methodologically addressed using the detection theory, and relevant formulas to assess the PAM performance are provided. The method is applied to the special case of North Atlantic right whales (NARW) in the Honguedo strait seaway of the Gulf of St. Lawrence. The relevant scales at stake in the area are first established before setting the parameters of realistic simulations fed with the actual shipping traffic, transmission loss (TL) from a regional acoustic propagation model accounting for the bathymetric and environmental structures, estimated NARW upcall source level (SL), and measured ship SLs of the local fleet. The tested scenarios include single hydrophone and hydrophone array PAM systems located either in the seaway, from buoys or gliders, or cabled to the coast. Three families of NARW upcall detectors, providing different levels of minimal signal to noise ratio (SNR) for detection, are compared for each scenario. A low falsealarm rate of 1 false detection per day is imposed and a probability of detection larger than 50% is retained as indicator of good performance. Results show that PAM systems located in the seaway have the lowest detection range and performance, because of the frequent masking of whale calls by the noise field radiated by each individual transiting ship. Moving the PAM system away from the seaway increases the detection probability, because the relative distance of the whale and the ships to the PAM increases, which favors higher occurrences of SNRs exceeding the detection threshold. Because the main noise sources (i.e. individual transiting ships) are localized in space, hydrophone arrays are showing the best performances as their directional hearing capacity with beamforming processing can greatly enhance the SNR. The most promising PAM system offering an effective solution to the detection of NARWs located in the Honguedo seaway, with reasonable and affordable efforts, appears to be the setup of two coastal-cabled hydrophone arrays, one on the Gaspesian coast and the other on the Anticosti Island.
LAGUERRE AND JACOBI ANALOGUES OF THE WARREN PROCESS

We define Laguerre and Jacobi analogues of the Warren process. That is, we construct local dynamics on a triangular array of particles so that the projections to each level recover the Laguerre and Jacobi eigenvalue processes of König-O’Connell and Doumerc and the fixed time distributions recover the joint distribution of eigenvalues in multilevel Laguerre and Jacobi random matrix ensembles. Our techniques extend and generalize the framework of intertwining diffusions developed by Pal-Shkolnikov. One consequence is the construction of particle systems with local interactions whose fixed time distribution recovers the hard edge of random matrix theory. An appendix by Andrey Sarantsev establishes strong existence and uniqueness for solutions to SDER’s satisfied by these processes.
3D Vehicle Detection on an FPGA from LiDAR Point Clouds

In this paper is presented a deep neural network architec- ture designed to run on a field-programmable gate array (FPGA) for detection vehicle on LIDAR point clouds. This works present a network based on VoxelNet adapted to run on an FPGA and to locate vehicles on point clouds from a 32 and a 64 channel optical sensor. For training the pre- sented network the Kitti and Nuscenes dataset have been used. This work aims to motivate the usage of dedicated FPGA targets for training and validating neural network due to their accelerated computational capability compared to the well known GPUs. This platform also has some constraints that need to be assessed and taken care during development (limited memory e.g.). This research presents an implementation to overcome such limitations and obtain as good results as if a GPU would be used. This paper makes use of a state-of-the-art dataset such us Nuscenes which is formed by several sensors and provides seven time more annotations than the KITTI dataset of the 6 cameras, 5 radars and 1 Lidar it is formed by, all with full 360 degree field of view. The presented work proves real- time performance and good detection accuracy when moving part of the CNN presented in the proposed architecture to a commercial FPGA.
IxaMed at PharmacoNER Challenge 2019

The aim of this paper is to present our approach (IxaMed) in the PharmacoNER 2019 task. The task consists of identifying chemical, drug, and gene/protein mentions from clinical case studies written in Spanish. The evaluation of the task is divided in two scenarios: one corresponding to the detection of named entities and one corresponding to the indexation of named entities that have been previously identified. In order to identify named entities we have made use of a Bi-LSTM with a CRF on top in combination with different types of word embeddings. We have achieved our best result (86.81 F-Score) combining pretrained word embeddings of Wikipedia and Electronic Health Records (50M words) with contextual string embeddings of Wikipedia and Electronic Health Records. On the other hand, for the indexation of the named entities we have used the Levenshtein distance obtaining a 85.34 F-Score as our best result.
Water clarification capabilities of indigenous plants used for water treatment by rural communities in Southeastern Nigeria

In this study, the value of indigenous plant seeds of southeastern Nigeria in the clarification of relatively turbid stream water (Otamiri River) was investigated. Four different plant seeds; Moringa oleifera (moringa), Zea mays (maize), Spheno stenocarpa (African bean) and Tetrapleura tetraptera seeds were crushed and used to treat a turbid water of 58 NUT, using 1 and 2 g of each seed type to treat 10 L of raw water drawn from the same location for one and 24 h. Subsequent physicochemical analysis such as electrical conductivity (EC), colour, turbidity, total dissolved solids (TDS), odour, taste, temperature pH, appearance, nitrate, copper and iron ions were carried out on each treatment bucket after 1 and 24 h of treatment. Suspended materials removal efficiency was found to increase with increasing dosage of the seeds in most cases. Values of TDS and total suspended solid (TSS) were below the WHO standards for both the alum and seed treated water with Zea mays and African bean seed powders recording TDS (36 mg/L each) and TSS (9 and 5 mg/L) each respectively after one hour treatment. Over 24 h treatment, both the TDS and TSS values of M. oleifera treated water decreased further from 52 to 38 mg/L and 19 to 7 mg/L respectively indicating that period of exposure is important in the use of this seed powder for water treatment. The turbidity reduction (43.0%) was achieved with M. oleifera seed powder after 1 g for 24 h, while one gram of Z. mays for one hour reduced turbidity by 81.0%. On the other hand, African bean seed powder on the other hand achieved poor turbidity reductions of 39.0 and 37.9% at 1 g treatment for 1 and 24 h periods, respectively, while T. tetraptera seed powder recorded 56.9 and 62.0% reductions after 1 and 24 h treatments, respectively. It would seem therefore from this study that Z. mays and T. tetraptera seed powders have better water clarification capabilities than the other seeds studied. There is need to evaluate the microbial characteristics of such seed treated water before recommendation for human use.
ENHANCING PRESERVICE TEACHERS’ EFFICACY BELIEFS IN MATHEMATICS

The present study sheds light on the factors affecting the development of preservice teachers’ efficacy beliefs in mathematics during fieldwork. Data were collected from interviews with 8 subjects in three consecutive intervals. The analysis of the data revealed that almost all subjects’ efficacy beliefs were improved during the period of fieldwork, mainly due to change in their mastery experiences in teaching mathematics. However, a number of other factors seemed to interact and form participants’ beliefs, providing support to the proposed unified model for studying teachers’ efficacy beliefs. Implications for the development of teachers’ training programs and for further research are drawn.
CONDUCTANCE CELLS BASED ON VAN DER PAUW THEOREM

Conductance cells designed and used according to the van der Pauw method are suitable for the absolute determination of the electrolytic conductivity of solutions and they are more advantageous for this purpose than other calculable cells. Three designs of such cells have been constructed and tested by the author. Results of experimental investigations confirm theoretical expectations and indicate that such a cell can be employed to substitute for standards of electrolytic conductivity. An absolute determination of electrolytic conductivity of 0.01 and 0.1 kmol/m NaCl solutions, with an uncertainty lower than 0.1%, has been obtained by the author using the cell of a new design.
The Impact of Community Service in College on Volunteerism in Saudi Arabia: An Interpretive Case Study

This study investigated the impact of college students’ volunteerism and the lasting effect their community service experiences had on post-graduate attitudes toward volunteerism. The research employed an interpretive case study approach of undergraduate female college students’ participatory experiences during their service learning programs. The study participants were students and graduates from two private nonprofit schools in Jeddah, Saudi Arabia. The study included three participant groups: female college students and graduates, college staff members, and the students’ family members and close friends. Data was collected through semi-structured, open-ended faceto-face, and Skype interviews. Post-interview data analysis identified emergent themes regarding the students’ past and current experiences with volunteerism, as well as their attitudes toward future volunteerism. Major themes that emerged from this study were: There is a major transformation among young women in Saudi schools and colleges, and relationship is imperative in Saudi culture for gaining research participants’ trust.
JBNU at MRP 2019: Multi-level Biaffine Attention for Semantic Dependency Parsing

This paper describes Jeonbuk National University (JBNU)’s system for the 2019 shared task on Cross-Framework Meaning Representation Parsing (MRP 2019) at the Conference on Computational Natural Language Learning. Of the five frameworks, we address only the DELPH-IN MRS Bi-Lexical Dependencies (DP), Prague Semantic Dependencies (PSD), and Universal Conceptual Cognitive Annotation (UCCA) frameworks. We propose a unified parsing model using biaffine attention (Dozat and Manning, 2017), consisting of 1) a BERT-BiLSTM encoder and 2) a biaffine attention decoder. First, the BERT-BiLSTM for sentence encoder uses BERT to compose a sentence’s wordpieces into word-level embeddings and subsequently applies BiLSTM to word-level representations. Second, the biaffine attention decoder determines the scores for an edge’s existence and its labels based on biaffine attention functions between roledependent representations. We also present multi-level biaffine attention models by combining all the role-dependent representations that appear at multiple intermediate layers.

An Alternative Approach to Maurer’s Universal Statistical Test

Statistical tests for randomness play an important role in cryptography since many cryptographic applications require random or pseudorandom numbers. In this study, we introduce an alternative approach to Maurer’s Universal Test. This approach allows us to test short binary sequences as small as 66 bits and to choose slightly larger block sizes. Moreover, it does not have an initialization part and requires less time to test a binary sequence.
eCOMPASS – TR – 001 A Web Application for Recommending Personalized Mobile Tourist Routes

Τhis article deals with the problem of deriving personalized recommendations for daily sightseeing itineraries for tourists visiting any destination. Our approach considers selected places of interest that a traveller would potentially wish to visit and derives a near‐optimal itinerary for each day of visit; the places of potential interest are selected based on stated or implied user preferences. Our method enables the planning of customised daily personalised tourist itineraries considering user preferences, time available for visiting sights in daily basis, opening days of sights and average visiting times for these sights. Herein, we propose a heuristic solution to this problem addressed to both web and mobile web users. Evaluation and simulation results verify the competence of our approach against an alternative method.
Modular system for fluorescence-based single photon generation using retro-reflector

Apparatus for fluorescence-based single photon generation includes collection optics and various setups for characterization. Managing this system often reveals complexity in such a way that adjusting in a small region changes optimal alignments of others. We suggest here a modular system, where the optimal alignment is given to each compartment and tested independently. Based on this concept, we built a system for single photon generation with fluorescence center in hexagonal boron nitride nano-flake, advantageous for scaling up the number of single mode fiber output and a high degree of stability. The system allowed for a practical use of single photon stream extended over an hour with a uniform count rate of small fluctuation levels. © 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement.
