STUDENTS’ ACADEMIC PERFORMANCE AND DROPOUT PREDICTION

Students’ Academic Performance (SAP) is an important metric in determining the status of students in any academic institution. It allows the instructors and other education managers to get an accurate evaluation of the students in different courses in a particular semester and also serve as an indicator to the students to review their strategies for better performance in the subsequent semesters. Predicting SAP is therefore important to help learners in obtaining the best from their studies. A number of researches in Educational Psychology (EP), Learning Analytics (LA) and Educational Data Mining (EDM) has been carried out to study and predict SAP, most especially in determining failures or dropouts with the goal of preventing the occurrence of the negative final outcome. This paper presents a comprehensive review of related studies that deal with SAP and dropout predictions. To group the studies, this review proposes taxonomy of the methods and features used in the literature for SAP and dropout prediction. The paper identifies some key issues and challenges for SAP and dropout predictions that require substantial research efforts. Limitations of the existing approaches for SAP and dropout prediction are identified. Finally, the paper exposes the current research directions in the area.
The complete plastome of Hyacinthoides non-scripta (L.) Chouard ex Rothm. (Asparagaceae)

Abstract The whole plastome sequence of Hyacinthoides non-scripta, was assembled and annotated in this study. This is the first complete plastid genome for the genus Hyacinthoides. The plastome is 155,035 bp long and consists of a large single-copy (LSC) region spanning 83,947 bp, a small single-copy (SSC) region spanning 18,496 bp, and two inverted repeat (IR) regions, each of which is 26,296 bp in length. There are 132 genes annotated in the plastome, of which the protein-coding gene infA has pseudogenized.
The Health Empowerment Program: A Primary Care – Area Agency on Aging Partnership

Family Practices and other primary care organizations are challenged to optimize care of high-risk/ high-need older adults. These are patients for whom a mix of unregulated chronic illnesses, cognitive impairment, and/or poor functional status predispose to repeated hospitalizations and poor outcomes. Care is further complicated by low confidence for self-management and need for linkages to community-based services and supports (Byhoff, Freund, & Garg, 2018). To better illustrate high-risk/high-need attributes, we introduce the cases of Mr. Andrews and Ms. Baker. Later we will see how our Health Empowerment Program (HEP) helped both of these patients.
A Local Positive (Semi)Definite Shift-Splitting Preconditioner for Saddle Point Problems with Applications to Time-Harmonic Eddy Current Models

A local positive (semi)deﬁnite shift-splitting preconditioner for non-Hermitian saddle point problems arising in ﬁnite element discretisations of hybrid formulations of time-harmonic eddy current models is constructed. The convergence of the corresponding iteration methods is proved and the spectral properties of the associated preconditioned saddle point matrices are studied. Numerical experiments show the ef-ﬁciency of the proposed preconditioner for Krylov subspace methods

Screen door effect reduction using mechanical shifting for virtual reality displays

The Screen Door Effect (SDE) is a common complaint amongst users of Virtual Reality (VR) headsets. SDE is characterized by a mesh-like artifact, much like looking through a screen door, on an image due to the space between pixels having a large enough angular size to be resolved through the viewing optics. Current generation VR displays exhibit SDE, distracting the user and breaking immersion. There are solutions currently in use in commercial VR headsets that reduce SDE in the form of dispersive elements placed in front of the display that effectively blur images from the display. However, these solutions only reduce the SDE, and functionally the blur is equivalent to reducing the quality of the optical stack. A method of image enhancement is to "shake" the display using piezo actuators, effectively shifting the pixels to enhance the image. This method can increase the apparent size of the pixels, reducing the gaps between pixels and leading to a reduction of SDE. In this paper, we will explore the limits of SDE reduction using this pixel shifting method with a square pixel architecture on a 9.4 μm pixel pitch RGBW display, and how that generalizes to other display architectures. We will find how different stimuli change with screen door reduction, analyzing solid color, text, and natural scenes. We will also explore what parameters to use in order to minimize SDE, adding to the other benefits of this solution and generalizing the parameters to all displays.
Game theoretical modelling of a dynamically evolving network Ⅱ: Target sequences of score 1

In previous work we considered a model of a population where individuals have an optimum level of social interaction, governed by a graph representing social connections between the individuals, who formed or broke those links to achieve their target number of contacts. In the original work an improvement in the number of links was carried out by breaking or joining to a randomly selected individual. In the most recent work, however, these actions were often not random, but chosen strategically, and this led to significant complications. One of these was that in any state, multiple individuals might wish to change their number of links. In this paper we consider a systematic analysis of the structure of the simplest class of non-trivial cases, where in general only a single individual has reason to make a change, and prove some general results. We then consider in detail an example game, and introduce a method of analysis for our chosen class based upon cycles on a graph. We see that whilst we can gain significant insight into the general structure of the state space, the analysis for specific games remains difficult.
Stratified sampling and bootstrapping for approximate Bayesian computation

Approximate Bayesian computation (ABC) is computationally intensive for complex model simulators. To exploit expensive simulations, data-resampling via bootstrapping was used with success in Everitt (2017) to obtain many artificial datasets at little cost and construct a synthetic likelihood. When using the same approach within ABC to produce a pseudo-marginal ABC-MCMC algorithm, the posterior variance is inflated, thus producing biased posterior inference. Here we use stratified Monte Carlo to considerably reduce the bias induced by data resampling. We also show that it is possible to obtain reliable inference using a larger than usual ABC threshold, by employing stratified Monte Carlo. Finally, we show that with stratified sampling we obtain a less variable ABC likelihood. We consider simulation studies for static (Gaussian, g-and-k distribution, Ising model) and dynamic models (Lotka-Volterra). For the Lotka-Volterra case study, we compare our results against a standard pseudo-Marginal ABC and find that our approach is four times more efficient and, given limited computational budget, it explores the posterior surface more thoroughly. A comparison against state-of-art sequential Monte Carlo ABC is also reported.

Application: Implications for TE teacher education programs, administration, and professional development are discussed.
Solving Schrödinger Equation for Finite Potential Well Using the Iterative Method

The quantum Finite Square Well (FSW) model is a well-known topic in most quantum mechanics (QM) books. A couple of equations can be derived from one dimensional Schrodinger equation for a finite potential well for describing the bound Eigen states within the well. Sometimes the FSW problem does not have an exact solution, yet, there are in fact exact solutions. In this work a computational techniques is adopted to find the exact solution for FSW. To achieve this computational solution, a computer program has been written in Basic language for calculating the Eigen state energy for a particle confined in finite potential well using the iterative method (IM). Six values of potential width have been studied with potential depth. The results showed that wider potential width led us to more bound states, while narrower potential width led us to less bound states. Six values of potential depth have been studied with potential width. The results showed that larger potential depth led us to more bound states, while smaller potential width led us to less bound states. A Comparison Between Finite and Infinite Potential Well has been also presented. The result of comparison showed that energy levels of an infinite well are much higher than that the corresponding energy levels for finite potential well. In general, the matching between the results of the iterative method and the graphical method (GM) proving that the iteration method can be regarded as a useful tool for describing the solutions of the 1-dimensional FSW problem.
Seminal Parameters and Sexual Behavior on Farm Rabbits Provided with a Diet Supplemented with Canola Oil at the Start of Puberty

In order to evaluate the effect on sexual behavior and spermatic parameters of white New Zealand rabbits, at the onset of puberty, they were fed a standard diet supplemented with canola oil (obesogenic). Two groups were formed; one of which received daily 180 g of a standard commercial diet supplemented with 13 ml of canola oil during 12 weeks, while the second grou p (control) were fed daily 180 g of only the standard commercial diet. Starting at 20-weeks of age, seminal volume, en masse and individual sperm motility, and sperm concentration per mm 3 were measured from each individual, as well as the behaviors olfactory exploration, chinning, and first and second attempt at mounting were assessed. No significant difference s were found between groups in terms of seminal volume, and en masse and individual sperm motility count and percentage (P>0.05). In relation to sexual behavior, the g roup fed with supplemental canola oil showed reduced the response time to females in the sexual behaviors of chinning, olfactory explora ion, and first and second attempt at mounting when compared to the control group (P<0.01). The data indicate that the addition of canola oil to standard rabbit diet at the start of puberty and continued for 12 weeks increases the body mass index and reduces the response tim in sexual behaviors such as olfactory exploration, chinning, and second attempt at mounting when interacting with female stimulus. Nevert heless, the seminal parameters did not show any modification. Other studies are needed to show the benefits or disadvantages of the addition of varying inclusion percentages of other vegetable oils, to evaluate their effects on reproductive efficiency in breeder male rab bits.
Biopsychosocial and Economic Determinants of Low Birth Weight in Jambi, South Sumatera: Path Analysis

Background: Low birthweight (LBW) is one of the main risk factors of neonatal mortality and morbidity. As such, it is an important public health issue particularly in developing countries. Worldwide, LBW shares around 15-20% of birth outcome. In Indonesia, LBW shares about 10.2% of birth outcome. In theory, the risk factors of LBW include not only biological aspect but also psychosocial and economic aspects. This study sought to estimate the biopsychosocial and economic determinants of LBW in Jambi, South Sumatera, using path analysis approach.Subjects and Method: This was an analytic observational study with case control design. The study was carried out at 20 community health centers in Jambi, South Sumatera, from December 2017 to January 2018. A total sample of 200 newborn infants consisting of 50 LBW and 150 normal birthweight newborn infants were selected for this study by fixed disease sampling. The dependent variable was birthweight. The independent variables were gestational age, infant sex, maternal mid-upper arm circumference (MUAC), maternal gestational stress, maternal education, family income at gestational period, and sanitation. Data on birthweight and MUAC were taken from obstetric record. The other data were collected by questionnaire. The data were analyzed by path analysis.Results: The risk of LBW decreased with gestational age ≥37 weeks (b= -5.06; 95% CI= -6.49 to -3.62; p<0.001), male sex (b= -0.99; 95% CI= -2.12 to -0.12; p= 0.081), low maternal stress (b= -2.35; 95% CI= 14.01 to -0.70; p= 0.005), and good sanitation (b= -1.04; 95% CI= -2.13 to -0.05; p= 0.062). Gestational age increased with family income (b= 1.74; 95% CI= 0.96 to 2.52; p<0.001). Low maternal stress was positively affected by high family income (b= 1.34; 95% CI= 0.197 to 2.50; p= 0.022). Good sanitation was positively affected by high family income (b= 0.71; 95% CI= 0.01 to 1.41; p= 0.046). High family income was positively affected by high education level (b= 1.37; 95% CI= 0.57 to 2.18; p= 0.001)Conclusion: The risk of LBW decreases with gestational age ≥37 weeks, male sex, low maternal stress, and good sanitation. LBW is indirectly affected by maternal education and family income.Keywords: biopsychosocial, economic, determinant, LBWCorrespondence: Iga Trisnawati.

Manipulating Soliton Polarization in Soliton Self-Frequency Shift and Its Application to 3-Photon Microscopy in Vivo

Soliton self-frequency shift (SSFS) enables energetic femtosecond pulse generation and deep-brain 3-photon microscopy (3PM) in animal models in vivo. The signal level in 3PM is currently limited by the available soliton energy. Here we propose a new maneuverable physical parameter that enables more energetic soliton generation through SSFS in a photonic-crystal (PC) rod. Through both theory and experiment, we demonstrate that circularly-polarized solitons are 1.5 times more energetic than previously reported linearly-polarized solitons. We further demonstrate comparative 3PM of the white matter layer in the mouse brain in vivo with both circularly-polarized and linearly-polarized solitons. The 3.7 times higher 3PM signal excited with circularly-polarized solitons indicates that this novel nonlinear optical technique is promising for 3PM.
Cross-modal retrieval by an end to end way

Cross-modal retrieval has attracted most attention in the recent years. For the image and text, how to measure the semantic similarity among them is still a challenging problem in cross-modal retrieval task. In our paper, we propose a cross-modal retrieval method that uses a CNN to obtain the semantic similarity between image and text. Most methods to solve this problem employ two separate parts for each modality to obtain the semantic similarity between them. However, in our work we just use a CNN to get the semantic similarity without having to use separate networks. In addition, we are aiming to solve the problem between long text and image, so we use the topic model to process the text. We evaluate our approach on Wikepedia dataset.
A Material Evidence Base for Investigating the Evolution of Chinese Medicinal Varieties and Cross-cultural Exchange

Relevance: Many Chinese medicinal materials (CMMs) have changed over centuries of use, particularly in terms of their botanical identity and processing methods. In some cases, these changes have important implications for safety and efficacy in modern clinical practice. As most previous research has focused on clarifying the evolution of CMMs by analyzing traditional Chinese materia medica (“bencao”) literature, assessments of historical collections are needed to validate these conclusions with material evidence. Aim of the study: Historical collections of Chinese medicines reveal the market materials in circulation at a given moment in time, and represent an underexploited resource for analyzing the evolution of Chinese herbal medicines. This study compares specimens from rare collections of CMMs with contemporary market materials. By highlighting examples of changes in botanical identity and processing that remain relevant for safe clinical practice in the modern era, this work aims to stimulate further research into previously unexplored historical collections of Chinese medicines. Materials and Methods: Three groups of herbal specimens were investigated from premodern collections of CMMs; these specimen groups are divided into separate chapters in the thesis presented here. The historical specimens researched here are stored in the UK in the Economic Botany Collections (EBC) of Royal Botanic Gardens Kew and in the Kam Wah Chung Museum in John Day, Oregon. The specimens were morphologically examined, photographed, and compared to authentic CMMs stored at the Bank of China (Hong Kong) Chinese Medicines Center at Hong Kong Baptist

A Fault Tolerance Aware Virtual Machine Scheduling Algorithm in Cloud Computing

Virtual machine (VM) scheduling in cloud computing is a complicated problem, particularly when taking reliability factors into account. In modern cloud datacenters, cloud providers may adopt fault tolerance techniques to improve their service reliability, which will in turn influence the performance metrics of VM scheduling. This influence is worthy of further investigation. However, few studies have considered fault tolerance in VM scheduling and explored its impact. This paper studies fault tolerance aware VM scheduling with cost optimization in clouds by considering the probability that a physical server may fail during execution. The optimization objective of the studied problem is to minimize the expectation of all cloud users' total execution costs under fault tolerance aware cloud environments. Then, a modified best fit decreasing (MBFD) algorithm is proposed based on a defined cost efficiency factor. The simulation results show that fault tolerance can significantly influence the execution time of VM requests, and the proposed MBFD algorithm can improve VM requests' successful execution rate, reduce the average execution costs of cloud users, and thus achieve better performance under fault tolerance aware cloud environments.
A closer look at attachment, sexuality, and couple relationships

In this study, the relationships between attachment patterns and relationship outcomes were explored through the mechanism of sexuality with two large samples from the U.S. In the first sample (N = 4,834), the associations between insecure attachment patterns, the number of committed and casual sexual partners, timing of sexual debut, and relationship status were explored. In the second sample, a nationally representative sample of recently married couples (N = 4212), an actor–partner model was used to explore the associations with attachment on the number of sexual partners and sexual timing and their subsequent influence on relationship and sexual satisfaction over two time points. The results indicated that, for Sample 1, insecure attachment was associated with both the number of casual and committed sexual partners and an increased likelihood of being single for men and women. For Sample 2, the actor–partner measures of attachment were associated with relationship and sexual satisfaction over two time points but had weak associations with the number of sexual partners and sexual timing.
A call to action: exploring and responding to educational developers’ workplace burnout and well-being in higher education

ABSTRACT There is a gap in research exploring stress, burnout, and well-being within the context of educational development. The purpose of this study was to examine the concepts of burnout and workplace well-being among educational developers across the international landscape. Thematic analysis from the survey responses (n = 210) revealed characteristics around four themes that both enhanced or hindered participants’ sense of well-being: a) colleagues, b) manager/director, c) institution/senior administration, and d) workplace. Our findings highlight the need to further amplify conversations related to burnout, as well as examine and promote workplace well-being for educational developers.
