Published: October 2020

This paper focuses on the synthesis of doped and undoped CuO nanoparticles using the sol-gel method,
which has been prepared and described. Supercapacitor applications of as-synthesized nanomaterials
were analyzed using cyclic voltammetry (CV), galvanostatic discharge (GCD) and electrochemical
impedance spectroscopic (EIS) analysis. The cyclic voltammograms illustrated the quasi-rectangular
shape which depicted the pseudocapacitance nature of the samples. The calculated specific capacitance
of the prepared samples was 180, 253 and 303 (F/g) corresponding to CuO, Fe-CuO and Ni-CuO,
respectively at the low current density and the EIS spectra show that the prepared Ni-CuO electrode
exhibits low charge transfer resistance.

Published: October 2020

In present study, a new organic dye 2-(4-chlorophenyl)-1-(4-methoxyphenyl)-4,5-diphenyl-1Himidazole
(CMI) containing phenyl donor with imidazole ring as π-linker and chlorophenyl group as
acceptor have been synthesized. The photophysical properties like solvato-chromism, optical band
gap and fluorescence lifetime are estimated using experimental as well as quantum chemical
computational techniques. Further, photosensitization of TiO2 nanoparticles from CMI dye has been
investigated using absorption, steady-state and time resolved fluorescence methods. The increase in
absorbance and a decrease in fluorescence spectra with different concentrations of TiO2 nanoparticles
confirmed the possibility of interactions between dye and TiO2 nanoparticles. Rehm-Weller relation
suggests that a decrease in fluorescence of CMI dye was due to photo-induced electron transfer process
and the Stern-Volmer studies suggest that the fluorescence quenching mechanism was due to combined
dynamic and static quenching process. Further, dye-sensitized solar cell using this newly synthesized
CMI dye has been fabricated and characterized for their photovoltaic performance under illumination.
Photovoltaic energy conversion efficiency and fill factor of the CMI dye were found to be 1.76% and
0.56, respectively.

Published: October 2020

This study focused on kinetic modelling of a specific type of multistep heterogeneous reaction comprising exothermic and endothermic
reaction steps, as exemplified by the experimental kinetic curves for the thermal decomposition of (E)-4-Bromo-2-[(phenylimino)methyl]-
phenol (4B2PMP) crystal. The crystal was grown by a slow evaporation method. The cell parameters and crystalline perfection of the
grown crystal were studied by single and powder X-ray diffractions. Thermal stability and phase change of 4B2PMP crystal were analyzed
by TG/DTA. The microhardness study has revealed the soft nature. UV-visible analysis reveals the wide range of optical window of the
optical transmission from 199 nm to 1100 nm. The bandgap of the crystal is found to be 3.24 eV. The FESEM of the crystals was
spherically shaped and consisted of a core-shell structure with internal aggregates. The antimicrobial activity of title crystal was tested
against different microorganisms by disc diffusion method. The results reveal that the title compound have effective antimicrobial activities.

Published: October 2020

Three metalloorganic derivatives of aluminium(III) [(CH3COCHCOOCH3)Al(OC6H4CH=NC6H4O)(EtOH)] (1), [(CH3COCHCOCH3)2Al(o-
MeC6H4O)]2 (2) and Al(OiPr)3 (3) were exploited as precursors of alumina through well-established sol-gel hydrolytic pathway. The
resultant white alumina powders (a), (b) and (c) were characterized by FTIR, powder XRD, TEM and EDX analyses. Formation of pure
alumina was confirmed through EDX and FTIR techniques. The powder XRD patterns of alumina samples established their existence in
γ-phase. The morphological examination of all oxidic ceramics through TEM illustrated that the alumina powders (a) and (b) were fine
and discrete nanorods whereas alumina powder (c) was highly agglomerated with irregular morphology.

Published: October 2020

In the present work, two different methods (sol-gel and biological) were adopted for synthesis of ZnO nanoparticles. The synthesized
nanoparticles were characterized for its optical, structural, photocatalytic, biological activities. Both synthesized nanoparticles demonstrated
a wurtzite hexagonal structure. The morphological analysis revealed that most of the particles spherical shape. The photocatalytic activity
of the synthesized nanoparticles was determined through the degradation of acid black 1 dye in which the biosynthesized ZnO NPs provided
good performance as compared to that the chemically synthesized ZnO NPs. Furthermore, antibacterial activity, the zone of inhibition of
bacterial growth was higher in the biosynthesized ZnO NPs and also antioxidant activity.
Improving utility and security of the shuffler-based differential privacy
Authors: Wang Tianhao , Ding Bolin , Xu Min , Huang Zhicong , Hong Cheng , Zhou Jingren , Li Ninghui , Jha Somesh
Published: October 2020

When collecting information, local differential privacy (LDP) alleviates privacy concerns of users because their private information is randomized before being sent it to the central aggregator. LDP imposes large amount of noise as each user executes the randomization independently. To address this issue, recent work introduced an intermediate server with the assumption that this intermediate server does not collude with the aggregator. Under this assumption, less noise can be added to achieve the same privacy guarantee as LDP, thus improving utility for the data collection task.

This paper investigates this multiple-party setting of LDP. We analyze the system model and identify potential adversaries. We then make two improvements: a new algorithm that achieves a better privacy-utility tradeoff; and a novel protocol that provides better protection against various attacks. Finally, we perform experiments to compare different methods and demonstrate the benefits of using our proposed method.
MorphoSys
Authors: Abebe Michael , Glasbergen Brad , Daudjee Khuzaima
Published: October 2020

Distributed database systems are widely used to meet the demands of storing and managing computation-heavy workloads. To boost performance and minimize resource and data contention, these systems require selecting a
distributed physical design
that determines
where
to place data, and
which
data items to
replicate
and
partition.
Deciding on a physical design is difficult as each choice poses a trade-off in the design space, and a poor choice can significantly degrade performance. Current design decisions are typically static and cannot adapt to workload changes or are unable to combine multiple design choices such as data replication
and
data partitioning integrally. This paper presents
MorphoSys
, a distributed database system that dynamically chooses, and alters, its physical design based on the workload. MorphoSys makes integrated design decisions for all of the data partitioning, replication and placement decisions on-the-fly using a learned cost model. MorphoSys provides efficient transaction execution in the face of design changes via a novel concurrency control and update propagation scheme. Our experimental evaluation, using several benchmark workloads and state-of-the-art comparison systems, shows that MorphoSys delivers excellent system performance through effective and efficient physical designs.
Variation in Genetic Relatedness Is Determined by the Aggregate Recombination Process
Authors: Veller Carl , Edelman Nathaniel B , Muralidhar Pavitra , Nowak Martin A
Published: October 2020

The genomic proportion that two relatives share identically by descent—their genetic relatedness—can vary depending on the history of recombination and segregation in their pedigree. Previous calculations of the variance of genetic relatedness have defined genetic relatedness as the proportion of total genetic map length (cM) shared by relatives, and have neglected crossover interference and sex differences in recombination. Here, we consider genetic relatedness as the proportion of the total physical genome (bp) shared by relatives, and calculate its variance for general pedigree relationships, making no assumptions about the recombination process. For the relationships of grandparent-grandoffspring and siblings, the variance of genetic relatedness is a simple decreasing function of r¯, the average proportion of locus pairs that recombine in meiosis. For general pedigree relationships, the variance of genetic relatedness is a function of metrics analogous to r¯. Therefore, features of the aggregate recombination process that affect r¯ and analogs also affect variance in genetic relatedness. Such features include the number of chromosomes and heterogeneity in their size, the number of crossovers and their spatial organization along chromosomes, and sex differences in recombination. Our calculations help to explain several recent observations about variance in genetic relatedness, including that it is reduced by crossover interference (which is known to increase r¯). Our methods further allow us to calculate the neutral variance of ancestry among F2s in a hybrid cross, enabling precise statistical inference in F2-based tests for various kinds of selection.
Project-Based Learning Approach in Teaching Information and Communications Technology
Authors: Agatep John Lenon E. , Villalobos Roy N.
Published: October 2020

The idea of outcomes-based education shifts educators from content-deliverer to project manager, facilitating the investigation of learning approaches and focusing on deeper learning to develop students’ essential skills for their career readiness. This study established the effectiveness of the project-based learning (PBL) approach in teaching topics on Information and Communications Technology (ICT) among selected students of three programs at President Ramon Magsaysay State University (PRMSU), Iba, Zambales during 2nd semester SY 2018-2019. The study employed a descriptive research method to describe and interpret the present condition and relate to the desired objectives. Descriptive and inferential statistics were used in analyzing data gathered. The study findings conclude that student-respondents had a “Fair” level of performance in ICT topics during the pre-test while “Very Good” after using the PBL approach; the PBL approach was effectively based on the result analysis of mean, frequency counts, standard deviation, and t-test computation. The variance test analysis revealed a significant improvement in students’ performance on ICT topics, as reflected in the post-test result. Recommendations are provided.
The Culprit Hormone: The Physiological Origin of School Violence amidst Middle School Students
Authors: He Danlong
Published: October 2020

The increasingly severe school violence has become an influential and notorious worldwide problem. The attribution of school violence determines the formulation of coping strategies. Unlike the analysis of family, psychological and social factors, long-term front-line work and follow-up studies have found that student violence’s physiological factors in adolescence are more significant than other factors. The decisive factor leading to school violence among middle school students is the secretion of sex hormones during adolescence, so hormones mostly cause violence. Attributing school violence to “sex instinct” does not deny the role of education; on the contrary, it recognizes the crux of the problem and provides the possibility of finding effective prevention and intervention measures. Using dopamine to antagonize hormones provides a physiological basis for education and violence intervention. Strengthening physical exercise, carrying out activities where boys and girls are present simultaneously, and building a harmonious teacher-student relationship and a friendly campus environment effectively prevent middle school students from campus violence.
Design and Application of Questions Based on Protocol-Guided Case Teaching
Authors: Li Caimin
Published: October 2020

As the core element of classroom teaching, questions play an essential role in constructing students’ knowledge systems and cultivating their ability to discover, explore, analyze, and solve problems. Therefore, the design and application of appropriate questions is the key to the success of classroom teaching. Teaching based on protocol-guided cases advocates question-centric teaching. It is suggested that teaching activities should be carried out around the discovery and solution of questions, promoting the teaching concept to change from lecture to inquiry, stimulating students’ interest and potential, and improving students’ comprehensive quality. This article mainly discusses the design and application of questions in middle school protocol-guided learning and discusses the basis and requirements of question design in protocol-guided case. With typical cases as the forerunner, strategic guidance is put forward to apply questions to integrate teaching plans.
An Empirical Study on the Construction of a Higher-Education Performance Allocation Model
Authors: Zhang Xiaoning
Published: October 2020

China’s financial input mechanism reform’s current development trend involves fully implementing budget performance management and constructing a performance-oriented financial allocation model. These are also essential measures in promoting the modernization of the national governance system and governance capacity. The current financial allocation method for higher education entails a financial supply policy based on per-student appropriation. A new performance-oriented system of higher- education financial allocation system is necessary to upgrade the per-student appropriation of a single flow, construct a close loop of financial allocation “fund flow,” optimize the allocation of financial resources for higher education, and guide higher-education institutions to deepen comprehensive reform and achieve high- quality development. Based on the actual situation and relevant data of 26 undergraduate universities in Jiangsu of China, this paper proposes a “double dimension” higher-education performance funding index system, conducts an empirical study with the data envelopment analysis model, and suggests policies on the construction, organization, and implementation of higher-education performance allocation models.
Yttrium-90 radiosynoviorthesis hosszú távú (10 éves) eredményei inflammált térdarthrosisban
Authors: Szentesi Margit , Nagy Zoltán , Géher Pál , Papp István , Kampen W. Uwe
Published: October 2020

Absztrakt:

Bevezetés: A radiosynoviorthesist (RSO) fájdalmas,
terápiarezisztens, krónikus synovitis kezelésére alkalmazzuk az 1950-es évek
óta, de a hosszú távú hatások felmérésére eddig nem készültek prospektív
ellenőrzött vizsgálatok. Célkitűzés: Ennek a prospektív,
obszervációs vizsgálatnak az volt a célkitűzése, hogy felmérje az izotópos
synovectomia hatékonyságát inflammált térdosteoarthritisben (OA) 10 éves nyomon
követésben. Módszer: Alapos előkészítés után a
radionuklid-kezelést 90-Yttrium-citráttal végeztük Kellgren–Lawrence I–II. (n =
69) és III. stádiumú (n = 72) osteoarthritises betegekben, intraarticularis
injekció formájában. Eredmények: A korai radiológiai stádiumban
levő osteoarthritises betegekben „kiváló/jó” eredményeket értünk el már 1 év
után az esetek 82,5%-ában, és 73,7%-ot a 8 éves kontrollvizsgálatokon. A
felmérés az ízületi fájdalomra, a mobilitásra és a mozgásfunkciók megtartására
vonatkozott. 10 évvel a beadás után az eredményesség 50%-ra csökkent,
feltehetően a korral járó degeneratív folyamatok progressziója miatt. A III.
stádiumú betegekben (akiknél az osteoarthritis előrehaladottabb volt) kezdetben
45,9%-os eredményt értünk el, és ez 41,2%-ra esett vissza a 8 éves utánkövetés
során. Ebben a csoportban a betegek száma csökkent a 8–10. évre, azaz a 8. évben
51 beteg maradt, majd a 9. évben 30 beteg, a 10. évben pedig 9 beteg. Az utolsó
évben az alacsony betegszám miatt a klinikai válaszok nem voltak biztonságosan
megítélhetők. Következtetés: Az osteoarthritises ízületekben
alkalmazott RSO hosszú távú eredménye a legtöbb betegben „kiváló” vagy „jó”
volt. A radiokolloid hatása hosszú távon fennmarad, a 8–10. éves gyengébb
eredmények az életkor előrehaladásával jelentkező degeneratív folyamatoknak és
az alacsony betegszámnak tudható be. Ismert, hogy a hatékonyság függ a kezdeti
diagnózistól (OA, RA, SpA, PsA, AHA, ReA stb.), a radiológiai stádiumtól
(Kellgren–Lawrence I–IV.), illetve a synovitis score-tól. Eredményeink a
nemzetközi tapasztalatokhoz hasonlóan arra utaltak, hogy a radiációs
synovectomia alkalmazása elsősorban az alacsonyabb radiológiai stádiumban levő
betegeknek javallott. Orv Hetil. 2020; 161(43): 1831–1839.

Published: October 2020

Absztrakt:

A pars petrosa cholesteatoma egy lassan növekvő, a temporalis csontot roncsoló,
elhúzódóan tünetmentes kórkép. A diagnózis felállítása gyakran késlekedik,
hiszen ritka volta miatt még a tapasztalt klinikusok sem gondolnak rá időben. A
végső diagnózist jellemzően számos eredménytelen középfülsebészeti beavatkozás
előzi meg. A modern radiológiai módszerek nemcsak a diagnózist, hanem a betegek
hosszú távú követését is lehetővé teszik. Retrospektív klinikai tanulmányunkban
a pars petrosa cholesteatomák sikeres műtéti kezelésére kívánjuk felhívni a
figyelmet, hazai beteganyagon első alkalommal elemezve a műtéti megoldások
eredményességét. Kezdeti tapasztalatainkat a nemzetközi irodalomból nyerhető
adatokkal hasonlítottuk össze. 2015 januárja és 2020 januárja között 6 beteget
(4 férfi, 2 nő) kezeltünk különböző lokalizációjú pars petrosa cholesteatomával.
Valamennyi beteg a cholesteatoma lokalizációjának megfelelő agyalapi sebészeti
beavatkozáson esett át. A betegek átlagos követési ideje 2,7 év volt. A betegek
átlagéletkora 47 év volt. A leggyakoribb panaszok a halláscsökkenés, gennyes
fülfolyás, szédülés, fülzúgás voltak. Egy beteg már a felvételekor a komplett
facialis paralysis tüneteit mutatta. A Sanna-féle osztályozás szerint 2-2
betegünk szenvedett supralabyrinthaer, illetve apicalis, 1-1 beteg pedig
masszív, illetve infralabyrinthaer pars petrosa cholesteatomában. Komplikáció
sem a peri-, sem a posztoperatív időszakban nem fordult elő. Egy betegnél
észleltük a residualis betegség radiológiai jeleit. A pars petrosa cholesteatoma
diagnózisa és terápiája komoly nehézséget jelent még a tapasztalt klinikusok
számára is. A korai diagnózist a nem jellegzetes tünettan ismerete és a modern
képalkotó modalitások teszik lehetővé. A sziklacsontot roncsoló patológiás
folyamat eltávolítására korszerű agyalapi sebészeti módszerek állnak
rendelkezésre. Ezek a műtétek napjainkban kombinálhatók a modern
hallásrehabilitációs módszerekkel. Orv Hetil. 2020; 161(43): 1840–1848.

Absztrakt:

A differenciált pajzsmirigydaganatok körébe tartozó papillaris és follicularis
carcinomákat együttesen nem medullaris pajzsmirigyráknak nevezzük, melyek az
összes pajzsmirigy-carcinoma 90%-át teszik ki. Ezen daganatok 5–10%-a családi
halmozódást mutat, és csak elenyésző hányaduk, mintegy 3–5%-uk köthető monogénes
öröklődést mutató tumorszindrómához. Az összes többi familiaris nem medullaris
pajzsmirigy-carcinoma hátterében egyértelmű genetikai eltérés nem észlelhető. A
családi halmozódást mutató nem medullaris pajzsmirigyrákok viselkedése,
agresszivitása és kimenetele rosszabb a sporadikus formáénál. Tizenhét évvel
ezelőtt, az akkor 45 éves nőnél derült fény pajzsmirigy szolid göbjének
hátterében papillaris carcinomájára. Műtétet és radiojód-ablatiót követően
levotiroxinkezelés mellett azóta tumormentes. Egy éve 41 éves leányánál
multinodularis struma műtéte során tokinfiltrációval és nyaki
nyirokcsomóáttétekkel járó papillaris carcinoma igazolódott. 39 éves másik
leányánál szűrővizsgálatot követően derült fény multiplex pajzsmirigygöbjeire. A
műtét során multiplex papillaris daganatot találtunk tokáttöréssel,
érinvázióval, valamint nyaki nyirokcsomóáttétekkel. Totális thyreoidectomiára,
valamint centrális nyaki blokkdissectióra került sor. Ezt követően
radiojód-terápiát, majd levotiroxint kapott. Esetünkkel szeretnénk felhívni a
figyelmet a familiaris nem medullaris pajzsmirigy-carcinomák jelenlétére, azok
agresszívebb természetére és emiatt a családszűrés, valamint a kezelési
stratégia megválasztásának fontosságára. Orv Hetil. 2020; 161(43):

Chiococca insularis (Ridley) C.M.Taylor & M.R.V.Barbosa (Rubiaceae) was described by Henry Nicholas Ridley in 1890, based on a collection he made on the island of Fernando de Noronha (Pernambuco, Brazil) in 1887. Since then, this species had not been collected again and has been treated as probably extinct. After 130 years, we discovered two new populations in the southwestern portion of the island, and the conservation status of the species is reassessed. A full description of the species, with previously unseen or unmeasured characters, habitat information and photographs of the plant and environment are provided.

ABSTRACT Objective: To assess suicide attempts in children seeking care at a Poison Control Center. Methods: Cross-sectional study with children (<12 years old) that attempted suicide and were cared at the Poison Control Center in Londrina, Paraná, Southern Brazil, from April 1985 to December 2018. Results: We identified 59 children, most of them females (74.6%), who used only one product (77.9%). Among the products involved, medications were the most important ones (88.1%). Neurological/psychiatric/muscular manifestations (61.0%) were the main symptoms presented. The main reason identified for the suicide attempt was conflicts with family and/or friends (27.1%). Suicide attempts were more frequent in 2001-2003 and 2016-2018. Conclusions: Suicide attempts occurred mainly in female children with a single agent (mainly medications), and the main reason was family conflicts..
VIOLENCE AGAINST CHILDREN AND ADOLESCENTS: NOTIFICATION AND ALERT IN TIMES OF PANDEMIC
Authors: Platt Vanessa Borges , Guedert Jucélia Maria , Coelho Elza Berger Salema
Published: October 2020

ABSTRACT Objective: Social isolation is currently identified as the best way to prevent the infection by the new coronavirus. However, for some social groups, such as children and adolescents, this measure carries a contradiction: the home, which should be the safest place for them, is also a frequent environment of a sad aggravation: domestic violence. This study aims to evaluate the notifications of interpersonal/self-inflicted violence available in the Information System for Notifiable Diseases in the State of Santa Catarina (southern Brazil), for the juvenile age group, before and during the new coronavirus pandemics. Methods: Cross-sectional, descriptive study of violence against children and adolescents (from 0 to 19 years) notified by health professionals by completing and entering the occurrence in the Information System for Notifiable Diseases of the State of Santa Catarina in 11 weeks in which the social isolation measure was instituted as mandatory, comparing with the same period before this measure. Results: During the study period, 136 municipalities in Santa Catarina made 1,851 notifications. There was a decrease of 55.3% of them in the isolation period, and the difficulties encountered in seeking protection and assistance institutions were listed. Conclusions: The society needs to be aware of possible cases of violence in the children and adolescent population. It is important to provide accessible, effective, and safe ways for complaints and notifications, as well as a quick response to the cases, aiming at protecting victims and minimizing damages to prevent the perpetuation of the violence.

Published: October 2020

Resumo A cartografia pode ser compreendida como uma estratégia que inspira a produção de pesquisas interessadas em traçar, acompanhar, investigar processualidades e propor movimentos de análise. Esse arranjo se mostrou potente para pôr o pensamento em movimento e suscitar sensibilidades que recortaram travessias e experimentações durante a pesquisa de doutorado sobre a fabricação do apoio em saúde no município de São Bernardo do Campo, onde o apoio foi proposto como dispositivo agenciador de redes. As ofertas de apoio variavam em função dos encontros e seus agenciamentos, na perspectiva de que a produção do cuidado e da gestão mobiliza táticas conectadas e indissociáveis. O artigo apresenta momentos e recortes dessa experiência em cartografia, por meio de pequenas narrativas que ilustram inquietações, acasos e imprevisíveis imanentes a esta geografia móvel e sua multiplicidade de possíveis. Nas andanças da pesquisa, foi possível acompanhar muitas maneiras de interrogar e produzir práticas cuidadoras entre os diferentes atores, que colocavam em circulação tensionamentos, disputas e a intensa conexão entre gestão e cotidiano do cuidado.

Bilimsel dayanaklarla doğruluğu kanıtlanmamış olmakla beraber, işitme yetersizliği olan bireylerin bir kısmının görsel bir dil olan işaret dili kullanmasına veya işitsel bilgiye nazaran görsel bilgiyi tercih etmesinden dolayı onların görsel öğreniciler oldukları düşünülür. Çağımızda ise, görsel okuryazarlık becerileri her eğitim kademesindeki birey için önemli bir beceri alanıdır. Bu sebeple, bu araştırmanın amacı 2018 Türkçe öğretim programındaki (1. sınıflar) görsel okuryazarlık beceri alanına ait olduğu düşünülen kazanımlarının belirlenmesi ve belirlenen kazanımlarla ilişkili etkinliklerin işitme engelliler ilkokullarında kullanılan Türkçe ders kitaplarında yer alma durumunun incelenmesi olarak belirlenmiştir. Çalışmanın verileri doküman incelemesi yoluyla elde edilmiş, kategorik kodlama matrisi kullanılarak analiz edilmiştir. İlkokul Türkçe 1 kitabında görsel okuryazarlık becerileriyle ilişkili 43 etkinlik, işitme engelli öğrenciler için hazırlanan Türkçe yardımcı ders kitabında ise 106 etkinlik tespit edilmiştir. Çalışmada işitme yetersizliği olan öğrenciler için hazırlanan yardımcı ders kitabının görsel okuryazarlık beceriyle ilişkili etkinlikler açısından zengin olduğu tespit edilmiştir. Fakat işitme engelli öğrenciler için hazırlanan Türkçe 1 yardımcı ders kitabında dinleme boyutuna ait kazanımlara ilişkin etkinliklerin bulunmadığı araştırma sonunda önemli bir eksiklik olarak tespit edilmiştir. Çalışma sonunda Türkçe ders ve etkinlik kitaplarında dil ve dile ait tüm boyutlarının bütüncül bir şekilde ele alınması ve görsel okuryazarlık becerilerinin dile ait tüm boyutlarda desteklenmesi yönünde öneriler geliştirilmiştir.

Bu çalışmanın amacı, dijital öykülerin Türkiye’de farklı öğrenim düzeylerindeki öğrencilerin Türkçe dil becerilerinin gelişimine etkisinin belirlenmesidir. Bu amaç doğrultusunda dijital öykülerin Türkçe dil becerilerinin gelişimine etkisini inceleyen araştırmaların meta analizi yapılmıştır. Meta analiz çalışmasına 11 araştırma dâhil edilmiştir. Meta analize dâhil edilen çalışmaların toplam örneklem büyüklüğünü deney grubunda 286 katılımcı, kontrol grubunda 280 katılımcı olmak üzere 566 öğrenci oluşturmaktadır. Meta analize dâhil edilen çalışmalar heterojen yapıdadır. Huni saçılım grafiğinin yayın yanlılığına ilişkin sonucuna ek olarak Orwin’in Güvenli N analizi, Duval ve Tweedie’nin Kırpma ve Doldurması ve Egger’in regresyon analizi ile yayın yanlılığının olmadığı tespit edilmiştir. Etki değerleri rastgele etkiler modeline göre hesaplanmıştır. Etki değeri hesaplamalarında Cohen’in d katsayısı kullanılmıştır. Araştırmada dijital öykülerin Türkçe dil becerilerinin gelişimi üzerindeki etkisine göre hesaplanan etki değerlerine, öğrenim düzeyi, yayın türü ve beceri alanı değişkenlerinin moderatör değişken etkisi de incelenmiştir. Moderatör değişken etkisinin belirlenmesinde Q testi ve p anlamlılık katsayısı kullanılmıştır. Araştırmada dijital öykülerin Türkçe dil becerilerinin gelişimi üzerinde yüksek düzeyde bir etkisi olduğu tespit edilmiştir. Moderatör değişken analizi sonucu incelendiğinde yayın türü ve beceri alanı moderatör değişkenleri için çalışmalar arası varyansın Türkçe dil becerilerinin gelişimi açısından anlamlı olmadığı; öğrenim düzeyi moderatör değişkeni için ise lisans düzeyi lehine anlamlı olduğu görülmüştür.
Políticas públicas e mudanças institucionais: as trajetórias dos agricultores familiares nas atividades de processamento de alimentos no Rio Grande do Sul – Brasil
Authors: Agne Chaiane Leal , Waquil Paulo Dabdab
Published: October 2020

A partir da década de 1990, as atividades de processamento de alimentos começaram a sofrer modificações, estimuladas pelo contexto político-governamental, que induziu novas formas de produção e comercialização no âmbito da agricultura brasileira. Dentre tais mudanças, várias políticas públicas foram desenvolvidas com a finalidade de regrar a produção, o processamento e os mercados dos alimentos da agricultura familiar. Apesar dos avanços nas discussões sobre os efeitos das políticas públicas nessa realidade, há lacunas para compreender em que medida elas influenciam as formas como as famílias interpretam e conduzem tais atividades. Para tanto, este artigo teve como objetivo analisar o papel que os programas e as políticas públicas exercem no processo de mudança institucional nas atividades de processamento desenvolvidas pela agricultura familiar. A pesquisa foi realizada em quatro regiões do Rio Grande do Sul (Coredes: Hortênsias, Jacuí Centro, Sul e Vale do Rio dos Sinos). Foram entrevistadas 64 famílias (agricultores familiares) que processam alimentos, utilizando um formulário semi-estruturado, diários de campo e observações. Para a análise dos dados, foram utilizadas as técnicas análise de conteúdo e escala likert. As famílias foram divididas em 4 grupos (trajetórias), que mostram as diferenças nas formas como iniciaram e modificaram tecnicamente as suas atividades de industrialização. Neste contexto, o Programa Nacional de Alimentação Escolar (PNAE) foi considerado como a política pública que influenciou a ocorrência de mudanças institucionais, identificadas pelas novas técnicas no ambiente da produção e pelas inovações nas relações de mercado. Tais mudanças são explicadas pelo processo de operacionalização dessa política pública, que demanda novas formas de planejamento produtivo das propriedades, além da organização social e coletiva para atender os contratos de comercialização.
El Bioetanol en base a maíz y su inserción en cadenas de valor en la Provincia de Córdoba, Argentina
Authors: Castro Mónica Beatriz , Emiliozzi Analia Laura
Published: October 2020

A demanda por biocombustíveis no mundo registrou um aumento sustentado, principalmente devido à crise do petróleo no início dos anos 70, bem como o produto das novas exigências para a produção sustentável, que mostram que a “energia verde” é capaz de reduzir a poluição ambiental. Na Argentina, a produção de biodiesel e bioetanol constitui dois segmentos de mercado que começam a ganhar terreno a partir de políticas de promoção, implementadas no início do segundo milênio. Na Província de Córdoba, dois terços do bioetanol à base de milho são produzidos e, considerando que o principal destino da produção de bioetanol na Argentina é o mercado interno, o trabalho se propõe a investigar, sob a ótica do desenvolvimento territorial, a cadeias de valor existentes, as possibilidades apresentadas pela produção de biocombustíveis para o desenvolvimento territorial, identificando os atores que podem influenciar a expansão desse mercado. Entrevistas e análise de dados secundários foram realizadas. As principais conclusões mostram que a indústria do bioetanol constitui um segmento de mercado com amplas possibilidades de gerar cadeias produtivas, sob formas de produção de acordo com os novos paradigmas, com altas exigências em inovação científica e tecnológica e ecologicamente sustentável.

Published: October 2020

O objetivo desse estudo é investigar o Arranjo Produtivo Local (APL) do vestuário em Espinosa/MG e seu impacto na dinamização da economia da região. O método levou em consideração dados secundários sobre a região e, principalmente, dados primários obtidos a partir de incursões em campo e de entrevistas semiestruturadas, com gestores das empresas e representantes do poder público, consultorias e instituições envolvidas direta ou indiretamente na governança do Arranjo. A pesquisa tem um cunho qualitativo, baseado na análise das informações coletadas. Os resultados apontam para uma experiência rica em relacionamentos e cooperação entre as empresas e os principais elos que participam do processo produtivo. O APL da Moda, como é conhecido, está localizado no extremo Norte de Minas Gerais, região semiárida distante dos grandes centros industriais e comerciais brasileiros, de forma que, por meio de iniciativa local, desenvolveu uma trajetória inesperada. Ele exerce notório impacto na economia regional, cria empregos, distribui renda, gera conhecimento, forma mão de obra e fornece estabilidade e dignidade às pessoas da região. No entanto, existem ainda algumas fragilidades nas ações coletivas e formas de cooperação institucional que precisam ser aprimoradas com o envolvimento de todos os agentes que compõem a governança do APL.

O método datiloscópico destaca-se como o método de identificação mais antigo, mais utilizado e o de melhor custo-benefício. Um dos grandes desafios para sua aplicação envolve a obtenção de um registro adequado em corpos carbonizados. A ação térmica faz com que haja a destruição em graus variados da epiderme e da derme, com afinamento, endurecimento e enrugamento cutâneos, dificultando a visualização dos sulcos e das cristas papilares e a revelação das impressões digitais. Vários são os métodos necropapiloscópicos disponíveis para uso nestes casos, mas como há particularidades em casos individuais, quanto maior o arsenal técnico disponível, maiores as chances de obtenção de um registo adequado. Neste relato é descrita a técnica necropapiloscópica com refração de luz indireta, utilizada na identificação de um corpo carbonizado. Esta técnica é simples, rápida e de baixo custo, o que permite sua aplicação mesmo em locais com pouca estrutura. Os autores esperam que este relato contribua para sua utilização na prática forense e que estimule estudos para que seja aprimorada tecnicamente.
Surgeon Grow
Authors: Stoff Laurie S.
Published: October 2020

This article examines the wartime experiences of Dr. Malcolm Grow, an American surgeon in the Russian Imperial Army during World War I. Stoff contextualizes Grow’s narrative within the broader historiographical neglect of Russia’s Great War. Grow’s account offers a rare frontline perspective, challenging traditional distinctions between combatant and non-combatant roles. While his memoir emphasizes military events, it also critiques the inadequacies of Russian wartime medical services. Stoff argues that Grow’s experiences illuminate the complexities of Russia’s total war and contribute to a deeper understanding of its human and institutional dimensions during the conflict

Authors: J. Haynes Philip , H. S. Main Kavit , L Pyne Alice
Published: October 2020

Atomic force microscopy (AFM) is a microscopy technique that uses a sharp probe to trace a sample surface at nanometre resolution. For biological applications, one of its key advantages is its ability to visualize substructure of single molecules and molecular complexes in an aqueous environment. Here, we describe the application of AFM to determine the secondary and tertiary structure of surface-bound DNA, and it’s interactions with proteins. Methods: Mica and DNA are both negatively charged at a neutral pH in aqueous solution. There are a number of methods used to facilitate the adsorption of DNA to the mica surface [9, 24, 29-31]. The following sections describe three methods to facilitate DNA and DNA-protein adsorption on mica, which are appropriate for imaging DNA in liquid (see Note 5). Mica substrates can be attached to a steel disc to be mounted on magnetic sample holders as common in AFM instruments (see Note 6).
