description: Simulation models have been informing the COVID-19 policy-making process. These models, therefore, have significant influence on risk of societal harms. But how clearly are the underlying modelling assumptions and limitations communicated so that decision-makers can readily understand them? When making claims about risk in safety-critical systems, it is common practice to produce an assurance case, which is a structured argument supported by evidence with the aim to assess how confident we should be in our risk-based decisions. We argue that any COVID-19 simulation model that is used to guide critical policy decisions would benefit from being supported with such a case to explain how, and to what extent, the evidence from the simulation can be relied on to substantiate policy conclusions. This would enable a critical review of the implicit assumptions and inherent uncertainty in modelling, and would give the overall decision-making process greater transparency and accountability.

description: Hemichordates are instrumental to understanding early deuterostome and chordate evolution, yet diversity and relationships within the group have been understudied. Recently, there has been renewed interest in hemichordate diversity and taxonomy, although current findings suggest that much hemichordate diversity remains to be discovered. Herein, we present a molecular phylogenetic study based on nuclear 18S rDNA sequence data, which includes 35 previously unsampled taxa and represents all recognized hemichordate families. We include mitochondrial 16S rDNA data from 66 enteropneust taxa and three pterobranch Rhabdopleura species, and recover colonial pterobranchs and solitary enteropneusts as reciprocally monophyletic taxa. Our phylogenetic results also reveal a previously unknown clade of at least four species of harrimaniid enteropneusts from cold waters, including Antarctica, the North Atlantic around Iceland and Norway, and the deep sea off Oregon. These small worms (1-5 mm in length), occur from 130 to 2950 m and are not closely related to other deep-sea harrimaniids, indicating that diversity of enteropneusts within the deep sea is broader than previously described in the literature. Discovery of this clade, as well as larger torquaratorids from Antarctica, strengthens hypotheses of close associations between Antarctic and deep-sea fauna.

description: In oviparous species, the embryonic environmentparticularly temperaturecan alter phenotype and survival of an individual by affecting its size as well as its metabolic rate. Previous studies have shown that incubation temperatures can affect sex ratio in birds; specifically, low incubation temperatures were shown to produce a male-biased sex ratio in zebra finches (Taeniopygia guttata) possibly because of a higher pre- or postnatal mortality rate in females. We hypothesized that sexes respond differently to suboptimal incubation temperature, leading to a male-biased sex ratio. To test this hypothesis, zebra finch eggs were incubated at 36.1 degrees, 37.5 degrees, or 38.5 degrees C and hatching success, hatchling mass, residual yolk mass, and pectoralis mass were measured. We found that while hatchling mass was similar between the sexes at 37.5 degrees C, female hatchlings were heavier at 36.1 degrees C, and male hatchlings were heavier at 38.5 degrees C. Pectoralis muscle mass was similar between the sexes at 36.1 degrees C; however, at 37.5 degrees C, female pectoralis mass was heavier at hatching than that of males. Females at 37.5 degrees C also had lower residual yolk at hatching compared with males, reflecting a higher use of energy by female embryos compared with male embryos at this temperature. In contrast, residual yolk was similar between the sexes at 36.1 degrees and 38.5 degrees C. Our results suggest that there are sex differences in how incubation temperature alters organ mass and yolk energy reserve; this can lead to a difference in survival at different incubation temperatures between the sexes. Taken together with previous studies showing that females alter incubation behavior with ambient temperature, rising ambient temperatures could impact phenotype and survival of avian offspring in a sex-specific manner.

description: Nowadays open data is entering the mainstream - it is free available for every stakeholder and is often used in business decision-making. It is important to be sure data is trustable and error-free as its quality problems can lead to huge losses. The research discusses how (open) data quality could be assessed. It also covers main points which should be considered developing a data quality management solution. One specific approach is applied to several Latvian open data sets. The research provides a step-by-step open data sets analysis guide and summarizes its results. It is also shown there could exist differences in data quality depending on data supplier (centralized and decentralized data releases) and, unfortunately, trustable data supplier cannot guarantee data quality problems absence. There are also underlined common data quality problems detected not only in Latvian open data but also in open data of 3 European countries.

Magnitude and Determinants of Risky Sexual Behaviors Among Regular and Evening Secondary School Students in Addis Ababa, Ethiopia: A Comparative Cross-Sectional Study.
Creators: name: Jemaneh, Sisay
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Background: Risky sexual behaviour is the activity that will increase the probability of being infected with sexually transmitted infections, or become pregnant or make a partner pregnant. Adolescents and youth constitute 33.8% of the total population of Ethiopia. These groups of population face varied vulnerabilities such as STI/HIV, unwanted pregnancy, fistula and etc. Objective: To assess the magnitude and determinants of risky sexual behaviours among regular and evening secondary school students in Addis Ababa, Ethiopia, a comparative cross sectional study 2018/19. Methods: A cross sectional study was conducted from February 1 to 30 2019. The calculated sample size was allocated to each grade by using a multistage sampling technique. A total of 604 students were enrolled in this study. Data were entered using Epi-info7 and exported to SPSS version 23 for analysis. Chi square was done to compare the risk between the two groups. Binary and multiple logistic regression analysis were used to see the association between the outcome and one and above one independent variable/s. Odds ratios at 95% CI were computed to measure the strength of the association between the outcome and the independent variables. P-value .0.05 was considered as a statistically significant. Results: From the 604 students who participated in the study, 79 (19.3%) of the regular students and 145 (74.4%) of the evening participants had sexual experience. 66 (16.4%) of the regular and 123 (63.07%) of the evening students had practiced risky sexual behaviours. Peer pressure (AOR=3.233, 95% CI=1.13, 9.192), watching pornographic movies (AOR=5.384, 95% CI=1.693, 17.118) and discussion on sexual issues (AOR=3.286, 95% CI= 1.181, 9.145) were factors significantly associated with risky sexual behaviours. Conclusions: Large proportions of students were engaged in to risky sexual behaviours specially the evening school students. Peer pressure, watching pornographic movies and discussions on sexual issues were significantly associated with risky sexual behaviours. Preventive measures like open discussion on sexual issues, prohibiting pornographic movie channels and monitoring students peer and activities are important.

description: The evolution of reproductive strategies depends on local environmental conditions. When environments are seasonal, selection favors individuals that align changes in key reproductive traits with seasonal shifts in habitat quality. Offspring habitat quality can decline through the season, and increased maternal provisioning to late-produced offspring may compensate. This shift, however, may depend on environmental factors that influence reproduction and are, themselves, subject to temporal changes (e.g., food abundance). We studied the brown anole lizard (Anolis sagrei) to demonstrate how prey abundance modifies seasonal changes in key reproductive traits. We bred lizards in controlled laboratory conditions across the reproductive season and manipulated the availability of food by providing some breeding pairs high prey availability and some low. Halfway through the season, we switched half of the breeding pairs to the opposite treatment. We measured growth of male and female lizards as well as latency to oviposit, fecundity, egg size, egg content (yolk, water, shell mass), and egg quality (steroid hormones, yolk caloric content) over this period. Higher prey availability enhanced lizard growth and some key reproductive traits (egg size, fecundity) but not others (egg content and quality). Moreover, we found that seasonal patterns of reproduction were modified by prey treatment in ways that have consequences for offspring survival. Our results demonstrate that seasonal changes in reproduction are dependent on fluctuations in local environmental conditions. Moreover, researchers must account for seasonal shifts in environmental factors and reproductive traits (and their interactions) when designing experiments and drawing conclusions about how the environment influences reproduction.

description: Low-dimensional representations, or embeddings, of a graph's nodes facilitate several practical data science and data engineering tasks. As such embeddings rely, explicitly or implicitly, on a similarity measure among nodes, they require the computation of a quadratic similarity matrix, inducing a tradeoff between space complexity and embedding quality. To date, no graph embedding work combines (i) linear space complexity, (ii) a nonlinear transform as its basis, and (iii) nontrivial quality guarantees. In this paper we introduce FREDE (FREquent Directions Embedding), a graph embedding based on matrix sketching that combines those three desiderata. Starting out from the observation that embedding methods aim to preserve the covariance among the rows of a similarity matrix}, FREDE iteratively improves on quality while individually processing rows of a nonlinearly transformed PPR similarity matrix derived from a state-of-the-art graph embedding method} and provides, at any iteration, column-covariance approximation guarantees in due course almost indistinguishable from those of the optimal approximation by SVD. Our experimental evaluation on variably sized networks shows that FREDE performs almost as well as SVD and competitively against state-of-the-art embedding methods in diverse data science tasks, even when it is based on as little as 10% of node similarities.

Year: 2019

description: Background: Cancer is a serious and life-threatening disease with negative effects on physical and psychological well-being of patients. Depression and anxiety are the commonest co-morbidities that adversely affects how people feel, the way they think and how they act and it is common among cancer patients. The impact of common mental disorder (CMDs) on cancer patients is not well recognized and managed in Ethiopia while there is a dearth of evidence on the effect of Psychotherapy on depression, anxiety and treatment outcome among cancer patients. Interpersonal psychotherapy is one therapy technique used to treat common mental disorders. Objectives:-To determine the Effect of Interpersonal Psychotherapy On treatment outcome among Breast Cancer patients with a common mental disorder at Tikur Anbessa specialized teaching Hospital (TASH), Addis Ababa, 2018/19. Methods: A parallel randomized control trial was employed on 124 breast cancer patients with CMD that are randomly selected from TASH oncology unit Out-patient department in weeks. Then study participants was randomly assigned as Intervention group (n=62) and control group (n=62) randomly in weeks and also single blinding was employed so as the outcome assessors are blinded of the belongingness of individuals to specific study group.To avoid information contamination patients were randomized in weeks.As an outcome measure we hypothesized treatment outcome as the dependent variable and it was assessed using a 30 item questionnaire of quality of life measurement scale. Depression and anxiety were the independent variables that are measured with hospital anxiety and depression measurement scale. Both tools were validated for use in Ethiopia.Psychotherapy was given for a month in a weekly basis. Then outcome was measured two weeks after the final therapy with similar tool that were used at baseline.Data was analysed using GLM (ANCOVA) to control the effect of confounders. With 95% confidence interval and P-value < 0.05 was used to declare the statistical significance. Result: Interpersonal Psychotherapy for Ethiopian use (IPT-E) had an effect on treatment outcome. IPT-E had a significant effect in decreasing anxiety, -5.76 with 95% CI (-7.10, -2.90) and depression, -4.74 with 95% (-6.44, -3.10) and with an IPT-E had also a significant effect on quality of life domains of physical, role, cognitive, emotional and social functioning with (p<0.05). And from the symptom scales insomnia and fatigue were decreased (p<0.05) also health-related quality of life was significantly improved (p<0.001). Conclusion and recommendation: Interpersonal psychotherapy had an effect on treatment outcomes, among breast cancer patients with common mental disorders. So health programmers may consider incorporating it as a treatment option in the oncology unit.

description: Robin Hirsch posed in 1996 the 'Really Big Complexity Problem': classify the computational complexity of the network satisfaction problem for all finite relation algebras A. We provide a complete classification for the case that A is symmetric and has a flexible atom; in this case, the problem is NP-complete or in P. The classification task can be reduced to the case where A is integral. If a finite integral relation algebra has a flexible atom, then it has a normal representation B. We can then study the computational complexity of the network satisfaction problem of A using the universal-algebraic approach, via an analysis of the polymorphisms of B. We also use a Ramsey-type result of Nešetřil and Rödl and a complexity dichotomy result of Bulatov for conservative finite-domain constraint satisfaction problems.

description: We study theoretically the influence of the temperature and disorder on the spin wave spectrum of the magnonic crystal Fe$_{1-c}$Co$_{c}$. Our formalism is based on the analysis of a Heisenberg Hamiltonian by means of the wave vector and frequency dependent transverse magnetic susceptibility. The exchange integrals entering the model are obtained from the \emph{ab initio} magnetic force theorem. The coherent potential approximation is employed to treat the disorder and random phase approximation in order to account for the softening of the magnon spectrum at finite temperatures. The alloy turns out to exhibit many advantageous properties for spintronic applications. Apart from high Curie temperature, its magnonic bandgap remains stable at elevated temperatures and is largely unaffected by the disorder. We pay particular attention to the attenuation of magnons introduced by the alloying. The damping turns out to be a non-monotonic function of the impurity concentration due to the non-trivial evolution of the value of exchange integrals with the Co concentration. The disorder induced damping of magnons is estimated to be much smaller than their Landau damping.

description: Graph models, like other machine learning models, have implicit and explicit biases built-in, which often impact performance in nontrivial ways. The model's faithfulness is often measured by comparing the newly generated graph against the source graph using any number or combination of graph properties. Differences in the size or topology of the generated graph, therefore, indicate a loss in the model. Yet, in many systems, errors encoded in loss functions are subtle and not well understood. In the present work, we introduce the Infinity Mirror test for analyzing the robustness of graph models. This straightforward stress test works by repeatedly fitting a model to its own outputs. A hypothetically perfect graph model would have no deviation from the source graph; however, the model's implicit biases and assumptions are exaggerated by the Infinity Mirror test, exposing potential issues that were previously obscured. Through an analysis of thousands of experiments on synthetic and real-world graphs, we show that several conventional graph models degenerate in exciting and informative ways. We believe that the observed degenerative patterns are clues to the future development of better graph models.

description: Describing the evolution of science is a salient work not only for revealing the scientific trend but also for establishing a scientific classification system. In this paper, we investigate the evolution of science by observing the structure and change of keyword co-occurrence networks. Starting from seven target physics fields and their initial keywords selected by experts from the Korean Physical Society, we generate keyword co-occurrence networks better to capture topological structure with our proposed approach. In this way, we can construct a more relevant and abundant keyword network from a small set of initial keywords. With these networks, we successfully identify the scientific sub-field by detecting communities and extracting core keywords of each community. Furthermore, we trace the temporal evolution of sub-fields with the time-snapshot keyword network, the resultant temporal change of the community membership explains the evolution of the research field well. Our approach for tracing the evolution of the research field with a keyword co-occurrence network can shed light on identifying and assessing the evolution of science.

description: Using information technology to reach mothers directly with health information customized to their stage of pregnancy. Mobile phones applications are able to quickly and easily disseminate information that will inform women of ways to care for themselves during pregnancy, dismiss tradition and misconceptions, highlight warning signs, connect women with local health services, reinforce breast feeding practices, explain the benefits of family planning, and make new mothers aware of how best to care for their babies. The aim of this project is to design information support system for maternal and childcare, to identify the current sources of maternal and child healthcare information and the need for a mobile based system, to design a prototype mobile application platform for providing maternal child healthcare information. A software development life cycle (SDLC) methodology of object-oriented approach applied to the study of the design system. Interview and document review were used as a main tool to capture the system requirement along with observation. Unified Modeling Language (UML) development techniques applied in the process of requirements capture, modeling, system analysis and design. SPSS and Visio Software were employed in analysis and design models diagramming. The results of this study show that an expectant women currently access maternal and child healthcare information from the media, brochure (or information sheet), Health extension workers (HEWs) and Health Development Army (HAD). The women in each development group are clustered in one of five networks. In developed countries, mobile phones are widely used to provide maternal and child healthcare information through mobile applications. Accessing maternal and child healthcare information directly to by expectant women and new mothers is an innovative way to empower women to take action to improve their own health and the health of their children and families. The researcher recommends the implementation of the design by Partnerships with health professionals , hospitals and healthcare NGO's to ensure the maternal and child healthcare information they provide, antenatal care clinic , health events and more can be informed the target population by means of mobile applications.

description: In this paper, we consider the classification problem of functional data including the sleeping energy expenditure (SEE) data, focusing on functional classification. Many existing classification rules are not effective in distinguishing the two classes of SEE data, because the trajectories of each observation have very different patterns for each class. It is often observed that some aspect of data such as the variability of paths is helpful in classification of functional data. To reflect this issue, we introduce a variable measuring the length of path in functional data and then propose a logistic model with fused lasso that considers the behavior of fluctuation of path as well as local correlations within each path. Our proposed model shows a significant improvement over some models used in the existing literature on the classification accuracy rate of functional data such as SEE data. We carry out simulation studies to show the finite sample performance and the gain that it makes in comparison with fused lasso without considering path length. With two more real datasets studied in some existing literature, we demonstrate that the new model achieves better or similar accuracy rate than the best accuracy rates reported in those studies.

description: Ranked set sampling (RSS) design as a cost-effective sampling is a powerful tool in situations where measuring the variable of interest is costly and time-consuming; however, ranking information about sampling units can be obtained easily through inexpensive and easy to measure characteristics at little or no cost. In this paper, we study RSS data for analysis of an ordinal population. First, we compare the problem of non-representative extreme samples under RSS and commonly-used simple random sampling. Using RSS data with tie information, we propose non-parametric and maximum likelihood estimators for population parameters. Through extensive numerical studies, we investigate the effect of various factors including ranking ability, tie generating mechanisms, the number of categories and population setting on the performance of the estimators. Finally, we apply the proposed methods to the bone disorder data to estimate the proportions of patients with osteopenia and osteoporosis status.

description: Let $r, \,m$ be positive integers. Let $x$ be a rational number with $0 \le x <1$. Consider $Φ_s(x,z) =\displaystyle\sum_{k=0}^{\infty}\frac{z^{k+1}}{{(k+x+1)}^s}$ the $s$-th Lerch function with $s=1, 2, \cdots, r$. When $x=0$, this is a polylogarithmic function. Let $α_1, \cdots, α_m$ be pairwise distinct algebraic numbers of arbitrary degree over the rational number field, with $0<|α_j|<1 \,\,\,(1\leq j \leq m)$. In this article, we show a criterion for the linear independence, over an algebraic number field containing $\mathbb{Q}(α_1, \cdots, α_m)$, of all the $rm+1$ numbers : $Φ_1(x,α_1)$, $Φ_2(x,α_1), $ $\cdots , Φ_r(x,α_1)$, $Φ_1(x,α_2)$, $Φ_2(x,α_2), $ $\cdots , Φ_r(x,α_2), \cdots, \cdots, Φ_1(x,α_m)$, $Φ_2(x,α_m)$, $\cdots , Φ_r(x,α_m)$ and $1$. This is the first result that gives a sufficient condition for the linear independence of values of the Lerch functions at several distinct algebraic points, not necessarily lying in the rational number field nor in quadratic imaginary fields. We give a complete proof with refinements and quantitative statements of the main theorem announced in [10], together with a proof in detail on the non-vanishing Wronskian of Hermite type.

description: Liquids near the glass transition exhibit dynamical heterogeneity, i.e. correlated regions in the liquid relax at either a much faster rate or a much slower rate than the average. This collective phenomenon has been characterized by measurements of a dynamic susceptibility $χ_4(t)$, which are sometimes interpreted in terms of the size of those relaxing regions and the intensity of the fluctuations. We show that the results of those measurements can be affected not only by the collective fluctuations in the relaxation rate, but also by density fluctuations in the initial state and by single-particle fluctuations. We also show that at very long times the average overlap $C(t)$ probing the similarity between an initial and a final state separated by a time interval $t$ decays as a power law $C(t) \sim t^{-d/2}$. This is much slower than the stretched exponential behavior $C(t) \sim {\rm e}^{-(t/τ)^β}$ previously observed at times within one or two orders of magnitude of the $α$-relaxation time $τ_α$. We find that for times longer than $10-100 τ_α$, the dynamic susceptibility $χ_4(t)$ is dominated by single particle fluctuations, and that $χ_4(t) \approx C(t) \sim t^{-d/2}$. Finally, we introduce a method to extract the collective relaxation contribution to the dynamic susceptibility $χ_4(t)$ by subtracting the effects of single-particle fluctuations and initial state density fluctuations. We apply this method to numerical simulations of two glass forming models: a binary hard sphere system and a Kob-Andersen Lennard-Jones system. This allows us to extend the analysis of numerical data to timescales much longer than previously possible, and opens the door for further future progress in the study of dynamic heterogeneities, including the determination of the exchange time.
