Out of Empire into Socialist Modernity
Authors: Marung Steffi 
Published: April 2021

AbstractIn this article the Soviet-African Modern is presented through an intellectual history of exchanges in a triangular geography, outspreading from Moscow to Paris to Port of Spain and Accra. In this geography, postcolonial conditions in Eastern Europe and Africa became interconnected. This shared postcolonial space extended from the Soviet South to Africa. The glue for the transregional imagination was an engagement with the topos of backwardness. For many of the participants in the debate, the Soviet past was the African present. Focusing on the 1960s and 1970s, three connected perspectives on the relationship between Soviet and African paths to modernity are presented: First, Soviet and Russian scholars interpreting the domestic (post)colonial condition; second, African academics revisiting the Soviet Union as a model for development; and finally, transatlantic intellectuals connecting postcolonial narratives with socialist ones. Drawing on Russian archives, the article furthermore demonstrates that Soviet repositories hold complementary records for African histories.

Uuringu eesmärk on ettevõtlusõpetajate kogemuste analüüsi alusel selgitada, kuidas rakendatakse ettevõtlusõpet Eesti kutsehariduses, keskendudes uurimisküsimusele, kuidas arendatakse ettevõtluspädevust ja rakendatakse ettevõtluspedagoogikat Eesti kutsehariduses. Teoreetiline lähenemine tugineb sotsiaal-konstruktivistlikest õppimisteooriatest lähtuvale lõimitud pedagoogika lähenemisele ning ettevõtluspädevuse mudelile. Andmestiku moodustavad 26 ettevõtlusõpetajaga tehtud intervjuud, millest osa on tehtud 2018., osa 2019. ja osa 2020. aasta kevadel. Fenomenoloogilise lähenemise raames kasutame induktiivset andmeanalüüsi meetodit. Tulemustest selgub, et ettevõtlusõpe on peamiselt ettevõtlikkuse toetamisele suunatud, sihtrühma spetsiifikat arvestav ja praktiline. Praktilise kogemuse ja eneseregulatiivse teadmise dialoogi puudumine teoreetilisega ning viimase nõrkus on peamised vajakajäämised ettevõtlusõppe pedagoogikas.

Uurimuse eesmärk oli välja selgitada, kuidas seostuvad hilisteismeliste väärtustega tajutud eakaaslaste ja õpetajate hoolivus, aga ka kooli asukoht ja pere sotsiaalmajandusliku staatuse näitajad. Uurimuses osales 528 kümnenda klassi õpilast (keskmine vanus 16,25). Nende väärtusi hinnati Schwartzi portreeküsimustikuga ning tajutud eakaaslaste ja õpetajate hoolivust kahe üksikväitega. Tulemused näitasid, et teismelised väärtustasid enim heasoovlikkust ja hedonismi. Väikelinna koolide õpilastele oli võim vähem oluline ning turvalisus olulisem kui suurlinna koolide õpilastele. Teismelised, kelle emal oli kõrgem haridus, pidasid kõikehaaravust vähem oluliseks kui need, kelle emal oli madalam haridustase. Kui eakaaslaste hoolivus teismeliste väärtustega ei seostunud, siis õpetajate hoolivus seostus enamiku väärtustega. Mida hoolivamatena tajuti õpetajaid, seda kõrgemalt väärtustati teiste inimeste heaolule, looduse hoidmisele ja reeglite järgimisele orienteeritud väärtusi.

Õpioskuste teadlik arendamine, kus õpetajad lastevanematega õpilasi süsteemselt juhendavad, on distantsõppe kogemuse valguses saanud tähenduslikumaks kui kunagi varem. Uuringu eesmärk oli selgitada, kuidas süsteemsel juhendamisel muutub õpilaste raporteeritud strateegiate kasutamine ja teadlikkus õpistrateegiatest ning kuivõrd õpilaste ja lastevanemate sekkumisjärgsed hinnangud õpistrateegiate tõhususele on seotud. Teadlikkus õpistrateegiatest tähendab õpilaste oskust hinnata strateegiate tõhusust ning teha valikuid tõhusamate strateegiate kasutamise kasuks. Sekkumisuuringul kasutati kolmanda klassi õpilastega programmi "Õpime mõttega". Sekkumisuuringu eel ja järel koguti andmeid õpilaste õpistrateegiate kasutamise ning hinnangute kohta, kasutades õpi- ja enesemääratluspädevuse teste. Lastevanematega korraldati vestlusringid õpistrateegiate teadlikkuse tõstmiseks ja hinnati nende teadlikkuse muutust sekkumise jooksul. Tulemused näitavad, et juba lühiajalise sekkumise tulemusena hindasid õpilased tõhusaid strateegiaid kõrgemalt. Lastevanemate teadlikkus tõhusatest õpistrateegiatest paranes ja ilmnes seos lastevanemate ja laste hinnangutes vähetõhusatele strateegiatele.

DIAGNOSIS OF CHRONIC RADIATION SYNDROME AT THE EARLY STAGE
Authors: Akleev A. 
Published: April 2021

Purpose: To describe early symptoms of chronic radiation syndrome (CRS) which is of utmost importance for diagnosing this rare radiation pathology in man.
Material and methods: The paper presents the findings of retrospective analysis of early clinical manifestations of chronic radiation syndrome (CRS) based on the data of a long-term medical follow up of the residents of the Techa riverside communities. Mean doses of postnatal exposure to red bone marrow in patients with CRS calculated with TRDS-2016D were 698.8±18.2 mGy, maximum doses were 3 603.9 mGy.
Results: Clinical picture of the CRS at the early stage was characterized by a set of non-specific changes including hematological, immune, neurological, and endocrine ones, as well as impairment of functions of a number of internal organs. The above-mentioned CRS symptoms developed in a certain sequence and depended on dose rate and absorbed dose to the organs. Prior to the development of a full-scale CRS clinical picture patients had a decrease in olfactory and taste thresholds, in vibration sensitivity, and changes in systemic immunity. Impairment of hematopoiesis, nervous and endocrine systems were also noted even at the early stage of CRS. Initial CRS changes were moderate and transient. The analysis of early CRS symptoms allows assuming that early CRS stage is a dysregulation pathology that is caused initially by radiation-induced disorders of immunohematopoiesis, nervous and endocrine systems. Visceral changes at the early CRS stage are secondary and functional. If exposure is terminated, they are reversible. However, if exposure continues at doses high enough to cause morphological changes in organs and tissues (dystrophy, fibrosis, hypoplasia, etc.), CRS course worsens and becomes irreversible.
Conclusion: It was demonstrated that CRS diagnosis at the early stage is very complicated. The key issue is to analyze the relationship of specific CRS symptoms development and dose rate and absorbed organ doses.

Numerical investigation of high birefringence and nonlinearity tellurite glass photonic crystal fiber with microstructured core
Authors: Wang Jiangyun 
Published: April 2021

In this paper, a novel photonic crystal fiber (PCF) based on tellurite glass with high birefringence and high nonlinearity is designed. Six small air holes arranged nearly rectangularly are added in the fiber core to form the near-elliptic core. By using the finite-element method with the help of COMSOL Multiphysics software, we investigate and simulate the birefringence, effective mode area, nonlinear coefficient, and the dispersion characteristics. Simulation results show that by optimizing the structure parameters of the core, at the wavelength of 1.55 µm, the birefringence is up to

Fast processing of underwater polarization imaging based on optical correlation
Authors: Zhang Huajun , Ren Mingyuan , Wang Hantao , Yao Jinren , Zhang Yu 
Published: April 2021

Underwater polarization differential imaging requires the estimation of different parameters, and the parameters can be accurately obtained by using optical correlation. However, optical correlation as a criterion function to estimate parameters takes a lot of time. To expedite the parameters’ estimation process, we propose two operations to process underwater polarization images. One operation is to update the analyzer angle range to reduce the number of processed images. The other is image downsampling, which reduces the amount of calculation for the corresponding images. In experiments, we confirmed the feasibility of our method. We have obtained an average of 42 times the calculation speed increase under the conditions of updating the analyzer angle range 3 times and reducing the image scale by 16 times. The results of our method are consistent with those of traditional methods. This established method is conducive to the practical application of underwater polarization differential imaging.
Evaluation of association studies and a systematic review and meta-analysis of CYP1A1 T3801C and A2455G polymorphisms in breast cancer risk
Authors: Yang Chen , He Xiao-Feng 
Published: April 2021

BackgroundNine previous meta-analyses have been published to analyze theCYP1A1T3801C and A2455G polymorphisms with BC risk. However, they did not assess the credibility of statistically significant associations. In addition, many new studies have been reported on the above themes. Hence, we conducted an updated systematic review and meta-analysis to further explore the above issues.ObjectivesTo explore the association on theCYP1A1T3801C and A2455G polymorphisms with BC risk.MethodsPreferred Reporting Items for Systematic Reviews and Meta-Analyses (The PRISMA) were used.ResultsIn this study, there were 63 case–control studies from 56 publications on theCYP1A1T3801C polymorphism (including 20,825 BC cases and 25,495 controls) and 51 case–control studies from 46 publications on theCYP1A1A2455G polymorphism (including 20,124 BC cases and 29,183 controls). Overall, theCYP1A1T3801C polymorphism was significantly increased BC risk in overall analysis, especially in Asians and Indians; theCYP1A1A2455G polymorphism was associated with BC risk in overall analysis, Indians, and postmenopausal women. However, when we used BFDP correction, associations remained significant only in Indians (CCvs. TT+TC: BFDP < 0.001) for theCYP1A1T3801C polymorphism with BC risk, but not in theCYP1A1A2455G polymorphism. In addition, when we further performed sensitivity analysis, no significant association in overall analysis and any subgroup. Moreover, we found that all studies from Indians was low quality. Therefore, the results may be not credible.ConclusionThis meta-analysis strongly indicates that there is no significant association between theCYP1A1T3801C and A2455G polymorphisms and BC risk. The increased BC risk may most likely on account of false-positive results.
The familial risk of infection-related hospitalization in children: A population-based sibling study
Authors: Miller Jessica E. , Carter Kim W. , de Klerk Nicholas , Burgner David P. 
Published: April 2021

Objective
To assess the risk of severe childhood infections within families, we conducted a sibling analysis in a population-based cohort study with genealogical linkage. We investigated the sibling risk of hospitalization with common infections, a marker of severity. We hypothesized that having siblings hospitalized for infection would increase the proband’s risk of admission with infection.

Study design
We used population data on Western Australian live-born singletons and their siblings between 1980 and 2014. Measures of infection were infection-related hospitalizations from discharge diagnostic codes. Exposure was having a sibling who had an infection-related hospitalization. Outcomes were infection-related hospitalizations in the child/proband. Probands were followed until an infection-related hospitalization admission (up to the first three), death, 18th birthday, or end of 2014, whichever occurred first. Infection risks were estimated by adjusted Cox proportional hazard models for multiple events.

Results
Of 512,279 probands, 142,915 (27.9%) had infection-related hospitalizations; 133,322 (26.0%) had a sibling with a previous infection-related hospitalization (i.e. exposed). Median interval between sibling and proband infection-related hospitalizations was 1.4 years (inter-quartile range 0.5–3.7). Probands had a dose-dependent increase in risk if sibling/s had 1, 2, or 3+ infection-related hospitalizations (adjusted hazard ratio, aHR 1.41, 95% CI 1.39–1.43; aHR 1.65, 1.61–1.69; aHR 1.83, 1.77–1.90, respectively). Among siblings with the same clinical infection type, highest sibling risks were for genitourinary (aHR 2.06, 1.68–2.53), gastrointestinal (aHR 2.07, 1.94–2.19), and skin/soft tissue infections (aHR 2.34, 2.15–2.54). Overall risk of infection-related hospitalization was higher in children with more siblings and with older siblings.

Conclusion
In this population-based study, we observed an increased risk of infection-related hospitalization in children whose siblings were previously hospitalized for infection. Public health interventions may be particularly relevant in families of children hospitalized with infection.

Published: April 2021

IntroductionPatients with minor ischemic stroke or transient ischemic attack represent a high-risk population for recurrent stroke. No direct comparison exists comparing dual antiplatelet therapy regimens—namely, Ticagrelor and Aspirin versus Clopidogrel and Aspirin. This systematic review and network meta-analysis (NMA) will examine the efficacy of these two different antiplatelet regimens in preventing recurrent stroke and mortality up to 30 days.Methods and analysisMEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) will be searched with the assistance of a medical information specialist. Two independent reviewers will screen studies for inclusion; eligible studies will include randomized controlled trials that enrolled adults presenting with acute minor ischemic stroke or transient ischemic attack and compared one or more of the interventions against each other and/or a control. The primary outcomes will be recurrent ischemic stroke up to 30 days from symptom onset. Secondary outcomes will include safety outcomes (I.e. major bleeding and mortality), functional disability, and outcomes up to 90 days from symptom onset. A Bayesian approach to NMA will be implemented using the BUGSnet function in R Software. Between group comparisons for time-to-event (TTE) and dichotomous outcomes will be presented in terms of hazard ratios and odds ratios with 95% credible intervals, respectively. Secondary effect measures of treatment ranking will also be estimated.Ethics and disseminationNo formal research ethics approval are necessary. We will disseminate our findings through scientific conference presentations, peer-reviewed publications, and social media/the press. The findings from this review will aid clinicians in decision-making on the choice of antithrombotic therapy in a high-risk stroke population and could be important in the development of future treatment trials and guidelines.Registration ID with Open Science Framework:10.17605/OSF.IO/XDJYZ.
