description: Despite improved investment in the education sector, a paradox persists which can be summed up as the inability of the system to provide basic skills training and harmful repetition practices that lead to early school leaving for a large part of the school population [1]. Thus, school dropout is one of the challenges faced by most schools in developing countries, particularly in Africa. In order to solve the dropout problem, a thorough understanding of the underlying factors is essential. Several researchers have identified and proposed causes, methods and strategies that will help reduce or suppress the problem. However, most of the proposed solutions have not shown promising results and the trend seems to be continuing in the education systems of several developing countries. In Morocco, for example, the dropout rate has increased from 10.8% in 2010-2011 to 10.4% in 2019-2020 in the college cycle according to data from the Ministry of National Education. In addition, machine learning has attracted a lot of attention when it comes to solving societal problems in different sectors, including the education sector [2,3]. In order to contribute to the analysis and reduction of the phenomenon, this research uses recent advances in data science and educational technology to understand and model the dropout phenomenon in order to lay the foundation for an early dropout detection system in junior high schools in the Rahmna region. From a methodological point of view, we use a four-step approach. We propose to conduct a systematic review of the determinants of school dropout in Africa on the one hand and the various options for combating school dropout, including the use of artificial intelligence, on the other. Second, we make a Moroccan adaptation of the questionnaire developed by the Quebec team for dropout screening [4], followed by the training of a predictive model for early school dropout screening in the Rahmna region. Finally, we propose a model of argumentation applied to the case of school dropout by providing justifications for the steps leading to an outcome and making explicit the arguments that support the decisions.

description: Обеднение мезентериального кровотока при дуктус-зависимых врожденных пороках сердца – один из главных патогенетических факторов развития некротизирующего энтероколита (НЭК). Присоединение НЭК в послеоперационном периоде повышает частоту летального исхода, ассоциируется с длительным пребыванием в стационаре, неблагоприятным неврологическим исходом. Выбор тактики энтерального питания может способствовать снижению риска гастроинтестинальных осложнений. Особый интерес представляют факторы, предрасполагающие к развитию НЭК у детей с врожденными пороками сердца. В обзоре обсуждаются критерии начала и увеличения объема энтерального питания в преди послеоперационном периодах, приводятся рекомендации ведущих кардиохирургических центров мира. Представлены подходы к обеспечению высокой потребности в энергии и нутриентах у детей с пороками сердца за счет энтерального питания.

description: We study the planar matching problem, defined by a symmetric random matrix with independent identically distributed entries, taking values 0 and 1. We show that the existence of a perfect planar matching structure is possible only above a certain critical density, $p_{c}$, of allowed contacts (i.e. of '1'). Using a formulation of the problem in terms of Dyck paths and a matrix model of planar contact structures, we provide an analytical estimation for the value of the transition point, $p_{c}$, in the thermodynamic limit. This estimation is close to the critical value, $p_{c} \approx 0.379$, obtained in numerical simulations based on an exact dynamical programming algorithm. We characterize the corresponding critical behavior of the model and discuss the relation of the perfect-imperfect matching transition to the known molten-glass transition in the context of random RNA secondary structure's formation. In particular, we provide strong evidence supporting the conjecture that the molten-glass transition at T=0 occurs at $p_{c}$.

description: Critical infrastructure (CI) services are crucial to the functioning of modern communities, and a single CI failure can cause cascading effects through a network of services, impacting an entire city. Challenges such as climate change and rapid urbanisation are increasing the risk of cascading effects of CI failure, particularly impacting the urban poor in peri-urban and informal settlements. This study uses a systems thinking approach to validate the hypothesis if CI services are susceptible to generating severe cascading effects in informal than formal settlements. Qualitative data was collected on cascading effects via interviews and focus group discussion in a formal and an informal settlement in Medellin, Colombia. The responses were analysed and structured using a service chain framework and a Causal Loop Diagram. Our findings show that cascading effects vary between the formal and informal contexts concerning CI service availability and accessibility and may be attributed to differences in demography, geography, socio-economic development, risk regulations, community coping capacities and other factors associated with urban development.

description: The beam-plasma instability, i.e. the response of the plasma bulk to the injection of supra thermal charged-particle beams, results to be appropriately characterized by a long-range interaction system. This physical system hosts a number of very interesting phenomena and, in particular, the emergence of long-lived quasi-stationary states. We characterize the self-consistent distribution functions of such out-of-equilibrium states by means of the Lynden-Bell's theory. The prediction of this theory, based on the statistical mechanics of the Vlasov equation, are checked against the outcomes of numerical simulations of the discrete system. Moreover, a phenomenological study of the effective resonance band for the system response is also addressed. A threshold value has been found in the initial spread of beam-particle momenta. This threshold allows to discriminate between the resonant and non-resonant regimes. The analysis of the thermalization of a few percents of the beam population characterized by large initial momenta (with respect to the main part of the beam itself) is also performed and it confirms and deepens the understanding of the physical meaning of the mentioned threshold.

The experience of successful re-entry to postsecondary education for college students who stopped out due to the effects of mental health conditions: a qualitative inquiry
Creators: name: Malenczak, Derek
Publisher: name: No Publisher Supplied

description: Education is considered a critical component to improve one’s standard of living, assume career-oriented valued social roles, and reduce poverty. As postsecondary education has become more accessible for people with mental health conditions over the last several decades, more students than ever are being afforded the opportunity to pursue an undergraduate degree. Despite the numerous mental health resources available, including counseling, accommodations, student groups, and/or workshops, there remains a subset of students who are unable to effectively manage their mental health condition while at college, and are forced to take a temporary leave from school (stopout).Little is known about the experience of those students when they resume their academic pursuits after a leave. The purpose of this study was to learn in-depth from students about their postsecondary re-entry experience following a stopout for a mental health reason. Alumni from the College Re- entry Program in New York City were recruited to participate in an interview about their re-entry experiences, with data saturation being reached after 11 participants.Episode profiles were created for each participant detailing their academic and mental health trajectories using the Sort and Sift, Think and Shift method of data analysis. In addition, a thematic analysis resulted in six themes generated, including the importance of building a healthy daily routine, having natural supports, and levering online learning. Study findings inform how postsecondary disability services as well as campus mental health re-entry policy may be improved to better support students with mental health conditions.

description: Представленный cистематический обзор литературы посвящен ключевым проблемам проведения нутритивной поддержки, возникающим при комплексном лечении пациентов с ишемическим инсультом и нетравматическим внутричерепным кровоизлиянием. Нутритивная поддержка является важной составляющей частью интенсивной терапии у пациентов с инсультом с неврологическим дефицитом. Проведение рациональной нутритивной терапии у данной категории пациентов требует учета особенностей как основной, так и сопутствующей патологии, в частности сахарного диабета и сердечно-сосудистых заболеваний. Углубленный анализ данных последних лет показывает, что ряд вопросов оценки гиперметаболического синдрома и дифференцированной коррекции расстройств белкового и энергетического обмена при различных клинических формах (ишемический, геморрагический) мозгового инсульта с наличием или отсутствием коморбидной патологии изучен недостаточно и ждет своего решения. Продолжается поиск новых методик и оптимальных алгоритмов нутритивной поддержки с последующей разработкой соответствующих клинических рекомендаций для применения у этой категории пациентов. Спорными остаются вопросы, касающиеся сроков начала нутритивной поддержки, потребности организма в белке и энергии, способов контроля адекватности и эффективности искусственного лечебного питания.

description: Высокие потребности в макрои микронутриентах организма беременных, проживающих на Крайнем Севере, связаны как с потребностями матери и растущего плода, так и с влиянием экстремальных факторов высоких широт. Только продукты уникальной культуры питания арктического народа ненцев традиционно позволяют восполнить возникающие потребности. Цель работы – изучение влияния традиционного питания на репродуктивное здоровье ненецких женщин, проживающих на территории Арктической зоны Западной Сибири. Материал и методы. Обследованы 619 коренных жительниц (ненцев) Ямальского, Надымского и Тазовского районов Ямало-Ненецкого автономного округа в возрасте 18–65 лет. Изучено влияние типа питания (местные или привозные продукты) на показатели репродуктивного здоровья (количество беременностей, число родившихся живыми детей, рождаемость, плодовитость, частоту самопроизвольных прерываний беременности, гестозов, угрозы прерывания беременности, оперативных родоразрешений) за 2013–2018 гг. путем анализа официальных статистических данных и собственных исследований, проведенных в форме анкетирования женского населения. Результаты. Потребление традиционных продуктов (оленина, продукты местного рыболовства, не реже 3 раз в неделю) ненецкими женщинами чаще сопровождается нормальным физиологическим течением беременности и родового периода (75,2 против 64,2%, χ2=8,7; p=0,003), снижением частоты осложнений во время вынашивания, таких как гестоз, угроза прерывания беременности в 1,5 раза (χ2=5,8; p=0,01) и родоразрешения путем операции кесарева сечения на 20% (χ2=16,6; p<0,001). В итоге семья, в рационе которой преобладают традиционные продукты, имеет статистически значимо большее число детей в семье (на 1 ребенка). Заключение. Сохранение нормального (привычного) уровня потребления продуктов северного оленеводства и речного рыболовства коренными женщинами будет способствовать поступлению в организм достаточного количества макрои микронутриентов, что даст возможность вынашивания и рождения более здорового поколения ненецкого общества.

description: This manuscript proposes a probabilistic framework to quantitatively assess communities’ resilience by simulating the state and serviceability of their infrastructure systems from the onset of a flood until the end of recovery. It comprises multiple interconnected models. Hazard model characterizes flood parameters (e.g., depth and velocity). Depth-damage curves estimate the damage to infrastructure systems’ components. The HEC-FIA mortality model characterizes the flood-induced casualties. Serviceability models determine the ability of interdependent infrastructure systems to meet the demand during the recovery process. The recovery models estimate the recovery duration and cost of damaged components probabilistically. The Monte Carlo analysis is employed to consider multiple relevant uncertainties, generating distributions of the flood-induced losses under various scenarios. The ratio of total losses to the gross regional product characterizes the community’s resilience. This framework facilitates the assessment of the impact of various resilience enhancement measures, guiding the selection of appropriate measures through a cost-benefit analysis.

description: Беременные составляют группу риска по развитию недостаточности или дефицита витамина D. Статус витамина D существенно влияет как на течение беременности, так и на развитие плода. Цель исследования – оценить содержание витамина D в сыворотке крови беременных женщин и его влияние на антропометрические показатели новорожденного. Материал и методы. Проспективное исследование проведено с октября 2018 г. по апрель 2020 г. с участием 71 женщины в возрасте от 19 до 40 лет со сроком беременности 12–15 нед. Для уточнения социально-демографических характеристик, анамнестических данных и пищевого рациона проводили опрос беременных. Общее количество витамина D [25(OH)D2 и D3] в сыворотке крови определяли иммуноферментным методом. Новорожденным измеряли антропометрические параметры: массу и длину тела, массо-ростовой коэффициент по отношению массы тела ребенка к длине тела. Результаты и обсуждение. Дефицит витамина D выявлен у 57,7% беременных, недостаточность – у 9,9%, оптимальный уровень – у 32,4%. У женщин с дефицитом витамина D чаще в анамнезе было невынашивание беременности, выкидыши у них встречались статистически значимо чаще, чем у женщин с оптимальным витамин D-статусом (отношение шансов – 9,06; 95% доверительный интервал 1,11–73,86, р=0,0396). Не установлено влияния других показателей (возраст, социальный статус, индекс массы тела женщин, количество беременностей) на статус витамина D у беременных. Существенных различий между показателями массы и длины тела ребенка по возрасту, оценке по шкале Апгар в зависимости от витамин D-статуса беременных не наблюдалось. Заключение. Оптимальный уровень витамина D наблюдается всего у 1/3 беременных, а его дефицит или недостаточность встречаются у 67,6%. Проведенное исследование не выявило влияния статуса витамина D у беременных в сроке 12–15 нед на антропометрические показатели новорожденного. Учитывая тенденцию к более низким показателям соотношения массы и длины тела к гестационному возрасту ребенка у матерей с дефицитом/ недостаточностью витамина D, необходимы дальнейшие исследования.

description: We determine the most general form of off-shell N=(1,1) supergravity field configurations in three dimensions by requiring that at least one off-shell Killing spinor exists. We then impose the field equations of the topologically massive off-shell supergravity and find a class of solutions whose properties crucially depend on the norm of the auxiliary vector field. These are spacelike-squashed and timelike-stretched AdS_3 for the spacelike and timelike norms, respectively. At the transition point where the norm vanishes, the solution is null warped AdS_3. This occurs when the coefficient of the Lorentz-Chern-Simons term is related to the AdS radius by $μ\ell=2$. We find that the spacelike-squashed AdS_3 can be modded out by a suitable discrete subgroup of the isometry group, yielding an extremal black hole solution which avoid closed timelike curves.

description: A promising approach to estimate the causal effects of peer review policies is to analyze data from publication venues that shift policies from single-blind to double-blind from one year to the next. However, in these settings the content of the manuscript is a confounding variable---each year has a different distribution of scientific content which may naturally affect the distribution of reviewer scores. To address this textual confounding, we extend variable ratio nearest neighbor matching to incorporate text embeddings. We compare this matching method to a widely-used causal method of stratified propensity score matching and a baseline of randomly selected matches. For our case study of the ICLR conference shifting from single- to double-blind review from 2017 to 2018, we find human judges prefer manuscript matches from our method in 71% of cases. Our results show that the double-blind review policy causes a negative change in the review score, politeness score, and sentiment score. This work hopes to contribute to the progression of text-based causal estimation methods and a case study of knowledge production in higher education institutions.

description: Human papillomavirus (HPV)-associated cervical cancer is a leading cause of cancer deaths in women. Here we present an integrated multi-omic analysis of 643 cervical squamous cell carcinomas (CSCC, the most common histological variant of cervical cancer), representing patient populations from the USA, Europe and Sub-Saharan Africa and identify two CSCC subtypes (C1 and C2) with differing prognosis. C1 and C2 tumours can be driven by either of the two most common HPV types in cervical cancer (16 and 18) and while HPV16 and HPV18 are overrepresented among C1 and C2 tumours respectively, the prognostic difference between groups is not due to HPV type. C2 tumours, which comprise approximately 20% of CSCCs across these cohorts, display distinct genomic alterations, including loss or mutation of the STK11 tumour suppressor gene, increased expression of several immune checkpoint genes and differences in the tumour immune microenvironment that may explain the shorter survival associated with this group. In conclusion, we identify two therapy-relevant CSCC subtypes that share the same defining characteristics across three geographically diverse cohorts.

description: Эмульсионные жировые продукты вследствие наличия водной фазы более подвержены окислительной порче, чем чистые масла и жиры, что требует использования антиокислителей. Исходя из социального запроса на использование в пищевой промышленности природных антиоксидантов распространение получают токоферолы, их смеси, а также аскорбиновая кислота. Однако большинство натуральных антиокислителей (витамины, растительные экстракты) имеет более низкую антиокислительную активность в жирах, чем синтетические, и требует внесения большего количества в продукт, что может негативно сказаться на его органолептических свойствах и стоимости готового эмульсионного жирового продукта. Одним из путей решения этой проблемы является использование новых мицеллированых форм антиокислителей. Мицеллирование различных видов водои жирорастворимых антиоксидантов позволяет повысить их удельную активность, что связано, по-видимому, с увеличением относительной поверхности взаимодействия в среде продукта. Разработка эмульсионных жировых продуктов с использованием новых технологических форм природных антиоксидантов с целью увеличения их сроков годности является актуальной и практически значимой. Цель исследования – сравнительная оценка эффективности действия природных антиоксидантов в нативной и мицеллированной формах в рецептуре маргарина. Материал и методы. В качестве объектов исследования были выбраны антиоксиданты (токоферолы, экстракт розмарина и аскорбиновая кислота) в нативной и мицеллированной формах для их внесения в маргарин с массовой долей жира 82%. В процессе хранения маргарина в его жировой фазе определяли перекисное и анизидиновое число в динамике. Результаты. Получены экспериментальные данные о воздействии исследуемых антиоксидантов различной технологической формы на образование первичных и вторичных продуктов окисления в маргарине в процессе хранения. Было определено, что введение мицеллированных форм различных антиоксидантов в маргарин в концентрации 0,015–0,03% наиболее эффективно замедляет образование продуктов окисления по сравнению с использованием их нативных форм в эквивалентном по активным веществам количестве (в среднем в 2 раза в периоде хранения 10 мес при температуре 23±3 °С). Заключение. Экспериментально установлено, что использование мицеллированных форм токоферолов, аскорбиновой кислоты и экстракта розмарина позволяет более эффективно создавать эмульсионные жировые продукты с увеличенным сроком годности.

description: We unify three approaches within the vast body of gauge-theory research that have independently developed distinct representations of a geometrical surface-like structure underlying the vector-potential. The three approaches that we unify are: those who use the compactified dimensions of Kaluza-Klein theory, those who use Grassmannian models (also called gauge theory embedding or $CP^{N-1}$ models) to represent gauge fields, and those who use a hidden spatial metric to replace the gauge fields. In this paper we identify a correspondence between the geometrical representations of the three schools.Each school was mostly independently developed, does not compete with other schools, and attempts to isolate the gauge-invariant geometrical surface-like structures that are responsible for the resulting physics. By providing a mapping between geometrical representations, we hope physicists can now isolate representation-dependent physics from gauge-invariant physical results and share results between each school. We provide visual examples of the geometrical relationships between each school for $U(1)$ electric and magnetic fields. We highlight a first new result: in all three representations a static electric field (electric field from a fixed ring of charge or a sphere of charge) has a hidden gauge-invariant time dependent surface that is underlying the vector potential.

description: We find a systematic reappearance of massive Dirac features at the edges of consecutive minibands formed at magnetic fields B_{p/q}= pϕ_0/(qS) providing rational magnetic flux through a unit cell of the moire superlattice created by a hexagonal substrate for electrons in graphene. The Dirac-type features in the minibands at B=B_{p/q} determine a hierarchy of gaps in the surrounding fractal spectrum, and show that these minibands have topological insulator properties. Using the additional $q$-fold degeneracy of magnetic minibands at B_{p/q}, we trace the hierarchy of the gaps to their manifestation in the form of incompressible states upon variation of the carrier density and magnetic field.

description: The Stanford-Sequoia Collaborative for Leadership (SSCL) is a two-year professional leadership development program piloted by the Center to Support Excellence in Teaching (CSET) in 2021, which aims to build the capacity of a cross-district cohort of leading teachers, site leaders, and district leaders. As part of my 2022-2023 POLS Field Project which I spent with CSET, I spent six months analyzing how learning environments have been designed to support the growth and development of participants’ leadership identity and stance, to strengthen their ability to practice leadership, and to build a strong community of leaders within and across participating districts. The work involved reviewing the program as well as its impact on participants and their respective schools and districts through site observations, analyses of program data and interviews with program participants. This deposit is a portfolio of the work done, including an analysis of SSCL’s learning environments by drawing on the framework developed by Bransford et al. (1998), presentation summaries to CSET, and findings from qualitative analysis of interviews.

description: The development of molecular signatures for the prediction of time-to-event outcomes is a methodologically challenging task in bioinformatics and biostatistics. Although there are numerous approaches for the derivation of marker combinations and their evaluation, the underlying methodology often suffers from the problem that different optimization criteria are mixed during the feature selection, estimation and evaluation steps. This might result in marker combinations that are only suboptimal regarding the evaluation criterion of interest. To address this issue, we propose a unified framework to derive and evaluate biomarker combinations. Our approach is based on the concordance index for time-to-event data, which is a non-parametric measure to quantify the discrimatory power of a prediction rule. Specifically, we propose a component-wise boosting algorithm that results in linear biomarker combinations that are optimal with respect to a smoothed version of the concordance index. We investigate the performance of our algorithm in a large-scale simulation study and in two molecular data sets for the prediction of survival in breast cancer patients. Our numerical results show that the new approach is not only methodologically sound but can also lead to a higher discriminatory power than traditional approaches for the derivation of gene signatures.

description: Производство продуктов с защищенным наименованием места происхождения (ПЗП) предполагает использование определенного сырья (сорт, органолептические и физико-химические характеристики и т.д.), что может быть подтверждено соответствующими испытаниями. В связи с этим актуально обоснование принципов выбора идентификационных критериев, позволяющих определять и подтверждать происхождение отечественных вин с защищенным наименованием места происхождения. Цель работы – разработка робастного дифференцирующего критерия, позволяющего определять подлинность и происхождение виноматериалов относительно эталона. Материал и методы. Авторами представлена кластеризационная методика, позволяющая на основе результатов испытаний и разработанных цифровых критериев идентификации подтверждать происхождение виноматериалов Краснодара и Ростова-на-Дону. В качестве критерия использованы данные анализа микрои макроэлементного состава виноматериалов этих регионов. Результаты. В статье постулируется: основная задача кластеризации; пути решения с позиций пищевой промышленности с использованием регрессионной модели пищевого продукта; информация по основным кластеризационным метрикам; области применения в зависимости от подхода к идентификации ПЗП. По результатам анализа содержания 21 минерального вещества (10 в мкг/л и 11 в мг/л) была построена регрессионная модель виноматериала. На основе модели были определены кластерные центры. Результирующая модель позволяет разделить два указанных винодельческих региона и сформировать пространственный цифровой дискриминационный критерий, основанный на близости к одному из установленных кластерных центров. Заключение. Предлагаемая модель может быть адаптирована для идентификации продукции различных отраслей пищевой промышленности.

description: Open-Source Software (OSS) projects result from contributions from people with all
 skill levels. Software development is a collaborative, social, knowledge-intensive activity,
 and human-centered (human aspects) factors such as communication and personality can
 impact software projects. These factors are essential for team diversity. There are three
 types of team diversity: informational (or knowledge), social, and values diversity. In
 this context, we have noticed that there’s a lot of interest in the software engineering
 community about the relationship between human factors and code quality. It is impor-
 tant to investigate if knowledge diversity (human aspects) affect test code quality. The
 literature has brought a number of studies investigating test code quality, but there is just
 a few empirical evidence on effects of knowledge diversity (e.g., educational background,
 level of professional experience, expertise, and skills) and test code quality. Whether we
 consider the prevalence of test smells in current software testing research, the number
 is way more limited. Test smells are bad implementations inserted by developers and
 can harm the comprehensibility and maintainability of test suites. Recent studies discuss
 developers’ perceptions of test smells and their impact on quality improvement, yet they
 have yet to discuss the effects of knowledge diversity in this regard. Our goal is to gather
 empirical evidence on such a relationship, with particular attention on the effect test
 smells can bring to software quality To achieve our goal, we adopted a combination of
 several research methods (e.g., surveys, interviews, and mining of GitHub repositories)
 to understand knowledge diversity and test code quality better. Analyzing the data from
 this combination of methods will lead us to compile a set of guidelines that will serve to
 support developers in preventing the insertion of test smells during the creation of unit
 test cases

description: The past few years have witnessed the great success of recommender systems, which can significantly help users find out personalized items for them from the information era. One of the most widely applied recommendation methods is the Matrix Factorization (MF). However, most of researches on this topic have focused on mining the direct relationships between users and items. In this paper, we optimize the standard MF by integrating the user clustering regularization term. Our model considers not only the user-item rating information, but also takes into account the user interest. We compared the proposed model with three typical other methods: User-Mean (UM), Item-Mean (IM) and standard MF. Experimental results on a real-world dataset, \emph{MovieLens}, show that our method performs much better than other three methods in the accuracy of recommendation.
The Next Step: Reframing the Vulnerability and Difficulties of Undocumented Students Through Higher Education Milestones

description: Over the last decade, undocumented students have been given access to the American dream of pursuing higher education which opens the doors to economic and social mobility. While undocumented students can pursue higher education, they can only achieve half the dream. The existence of education access policies is not enough for these students to access the benefits of higher education. This project seeks to understand the experiences of undocumented students as they pursue higher education with the existence of the following education access policies: Assembly Bill 540 and the California Dream Act. These two laws open the doors to higher education for undocumented students in California by providing access to in-state tuition and state financial aid, respectively. Through this project, I sought to learn what barriers these policies fail to address and how the experience of undocumented students differs with DACA and no DACA. My thesis will center on three higher education milestones: high school to college, navigating undergrad, and post-college graduation. I structured my interview guide around these three milestones to understand how my participants experienced these transitions. In the 11 interviews I conducted, I found themes of self-advocacy, exclusion from the typical college experience, the necessity of high levels of resilience, and differences in how both groups of students (DACA and no DACA) experience the transition post-college graduation. Undocumented students must achieve high levels of resilience and self-advocacy to persevere through the barriers they face pursuing higher education. I argue that pursuing higher education provides undocumented students without DACA protection from the limitations of their immigration status while DACA students are able to access the benefits of higher education. Lastly, I conclude that the existence of education access policies is not sufficient to support the journey of undocumented students pursuing higher education.
