Development and Characterization of Rice Lines Carrying both Sub1 and Anaerobic Germination Tolerance: SUB1A does not Inhibit AG [RESEARCH NOTE]
Authors:   International Rice Research Institute, Los Baños, Laguna, Philippines, Vergara Georgina , Ismael Abdelbagi ,   Institute of Crop Science, University of the Philippines Los Baños, 4031, College, Laguna, Philippines
Published: April 2024

Accelerated coleoptile elongation in flooded soils allowed seedling shoots to reach the water surface to maintain gas exchange and CO2 fixation. Rice genotypes with tolerance of flooding during germination (anaerobic germination, AG) exhibited fast coleoptile elongation as an escape mechanism. On the other hand, tolerance of complete submergence during the vegetative stage, conferred by SUB1A, involved growth retardation to conserve energy for maintenance metabolism, with resumption of growth upon de-submergence. Combining genes controlling flood tolerance at these two stages with contrasting mechanisms was necessary in flood-prone areas for protection during germination under direct seeding and during vegetative stage. Breeding lines combining AG + Sub1 were used to determine the timing of the expression of SUB1A and elucidate its impact when combined with tolerance of flooding during seed germination and to evaluate seedling performance under complete submergence. Time-points for SUB1A expression in IR64-Sub1 and AG + Sub1 lines germinated under hypoxia or submerged for 30 h at vegetative stage showed that during flooding treatment, SUB1A and SUB1C expression was inhibited in young seedlings (< 6 d old) in IR64-Sub1 and at 2 and 4 d of seedling growth under hypoxia in AG + Sub1 materials. SUB1A was weakly expressed in AG + Sub1 starting at seedling age of 6 d following 1 d of complete submergence, indicating that expression of SUB1A may be stage-specific. Physiological tests showed higher percentage of survival of AG + Sub1 lines under hypoxia, comparable to that of AG tolerant check and significantly different from intolerant check IR42, indicating that the presence of SUB1A does not affect tolerance of flooding during germination. When seedlings were completely submerged, Sub1 expression was not inhibited by the presence of AG and tolerant genotypes showed suppressed elongation that was significantly different from intolerant check IR42. Despite their contrasting mechanisms of tolerance, combining AG with Sub1 provides multiple flooding tolerance from early crop establishment using direct seeding through to the vegetative stages.
Molecular Mimicry of NodA Genes by an N-acetylmuramoyl-L-alanine Amidases Gene in a Nodule Forming Staphylococcus cohnii [RESEARCH NOTE]

A rare, nodule-forming, Gram-positive bacterium (Sub4) was isolated from the forage and cover crop Pueraria phaseoloides, which aligned at 99.26% sequence identity to a partial 16S rDNA sequence of Staphylococcus cohnii sp. This was the first record of a strain/species of Staphylococcus capable of independent, unassisted nodule formation in a legume host. When a nodA gene was sought by PCR using a pair of gene-specific primers synthesized using a related (Firmicutes) Paenibacillus sp. nodA gene, the reaction yielded a PCR product of similar size but a distinct identity. The resulting ~400bp PCR product coded for a likely N-acetylmuramoyl-L-alanine amidase and not an acyltransferase. It may be inferred that the N-acetylmuramoyl-L-alanine amidase gene was amplified due to sequence similarities/mimicry between 2 cosmetically unrelated loci. There was also an analogy in protein backbones between homology models of the Sub4 N-acetylmuramoyl-L-alanine amidase and a Paenibacillus nodA gene product, which also suggests that the 2 protein families may have an evolutionary relationship. When the phylogeny of the sequenced locus was inferred, a unique clade with high bootstrap support was formed by the sequence under study with an Azorhizobium nodA gene. Azorhizobia were distinct in relation to their nodule formation on stems and their ability to fix nitrogen in the free-living and the symbiotic forms. N-acetylmuramoyl-L-alanine amidases may have roles to play in remodeling peptidoglycan for LysM receptor interactions, likely without nod factors.

Published: April 2024

Sustainability of the transplanted and flooded rice system is threatened by water and labor availability in many Asian countries including the Philippines. Dry direct seeding instead of transplanting is evolving as a viable crop establishment option to deal with labor and water shortages. Two experiments from July 2020 to June 2021 were conducted to determine the effect of different seeding rates [20 kg ha-1 (SR20), 40 kg ha-1 (SR40), 60 kg ha-1 (SR60), and 120 kg ha-1 (SR120)] on the growth, grain yield, and yield components of 2 rice varieties that were established through direct seeding in dry tilled soil and subsequently grown under flooded conditions. Seeding rates of SR40, SR60, and SR120 produced comparable and not significantly different grain yields. However, these seeding rates produced significantly higher grain yields than SR20 (20 kg ha-1). The lower grain yield in SR20 was due to lower panicle density which caused a reduction in sink size. Strong compensation between the number of panicles and the number of grains per panicle was observed in different seeding rates in both varieties. Plants grown at the high seeding rate (120 kg ha-1) had a higher number of panicles but with lower filled grains per panicle. On the other hand, plants grown at the low seeding rate (20 kg ha-1) had more filled grains per panicle with a lower number of panicles per m2. Yield component compensation to maintain desirable sink size was effective at 40 and 60 kg ha-1 seeding rates, although not enough at 20 kg ha-1. Moreover, a longer duration of tiller production was observed at the low seeding rate (SR20) which resulted in a higher number of late emergent tillers with poor grain production. The seed rate of 120 kg ha-1 in this study did not result in yield reduction due to an excessive number of tillers that eventually reduced the number of grains per panicle as observed in other studies. Compensation was between panicle number and grain number per panicle. SR40 and SR60 had similar yield levels with SR120 due to compensation among yield components, these seeding rates would be more attractive to farmers due to lower seed costs.

This paper evaluated the effects of different polishing times and regular cooking on the phytochemical properties and antioxidant activities of black rice Brillante, red rice Minaangan, and white rice NSIC Rc 160. Rice samples were polished for 0, 15, 30, and 45 s, and were cooked using their optimum cooking water ratio. The samples were then characterized for their phytochemical properties [total anthocyanin content (TAC), total phenolic content (TPC), and total flavonoid content (TFC)] and antioxidant activities [DPPH-radical scavenging activity (DPPH-RSA) and ferric reducing antioxidant power (FRAP)]. Pearson’s correlation analysis (PCA) was employed to determine the strength of the linear relationship between the polishing times and different parameters tested. Results showed that the pigmented rice samples had significantly higher phytochemical properties and antioxidant activities than the white rice sample. Polishing of rice samples considerably reduced their TAC (4.8% to 52.7%), TPC (13.0% to 65.2%), TFC (11.2% to 61.5%), DPPH-RSA (35.0% to 79.9%), and FRAP (11.8% to 68.5%). Cooking also decreased their TAC (24.1% to 92.6%), TPC (14.3% to 78.0%), TFC (14.4% to 74.2%), DPPH-RSA (38.9% to 84.6%), and FRAP (37.0% to 92.8%). Moreover, PCA showed that the polishing time had a strong to very strong negative correlation with phytochemical properties (-0.8809 to -0.9846) and antioxidant activities (-0.8106 to -0.9763). This study concluded that the polishing and cooking significantly affected the phytochemical content and antioxidant activities of white and pigmented rice cultivars. The information generated can be used as a basis for selecting suitable processes to better preserve the antioxidants of pigmented rice.

Published: April 2024

The problem of the flow of compressible laminar gas flows through a three-dimensional channel with a sudden expansion in the shape of a square parallelepiped is formulated. The Navier-Stokes equations are solved. When solving equations, spatial derivatives are approximated with a high order of accuracy. The pseudo-implicit right-hand side algorithm is used to integrate equations over time. The computational process is parallelized using MPI technology and is carried out on the Uran supercomputer. The range of Reynolds numbers from 100 to 600 is considered. The changes in the coordinates of attachment points in various planes depending on the Reynolds number are shown. With increasing Reynolds number, the magnitudes of small separation zones are first increasing and then decreasing, while large zones only increase. The field of the vortex vector is analyzed for different Reynolds numbers. The center of rotation shifts, and disturbances penetrate further into the channel. The profiles of the longitudinal velocity at various points of the channel are presented. A tendency towards a symmetrical state is revealed for all Reynolds numbers considered in the work.
Study of devitrification of amorphous titanium nanoparticles in vacuum and in an aluminum shell: molecular dynamics modeling
Authors:   Polzunov Altai State Technical University, Poletaev Gennady M. , Kovalenko Viktor V. ,   Siberian State Industrial University
Published: April 2024

The process of the devitrification of titanium nanoparticles in a vacuum and in an aluminum shell was studied at heating rate of 5∙1011 K/s by the molecular dynamics method. Additional consideration of the influence of the aluminum shell is related to the solution of the issue of reducing the temperature of the initiation of the high-temperature synthesis reaction in the Ti-Al system in mixtures subjected to preliminary mechanical activation. It is shown that the change in the devitrification temperature compared to a bulk sample is inversely proportional to the particle diameter: as the particle size decreases and, accordingly, the proportion of atoms near the interface increases, the devitrification temperature increases. The presence of an aluminum shell leads to a significant increase in the devitrification temperature of titanium nanoparticles - for the considered sizes of nanoparticles (diameter from 1.75 to 11 nm) the difference was about 200 K. Thus, a decrease in the size of titanium particles and the presence of an aluminum shell increase the temperature range for the existence of the amorphous phase of titanium. The mechanisms of the nucleation of the crystalline phase in particles in a vacuum and in an aluminum shell are significantly different: in the first case, crystal nuclei are formed near the surface; in the second, on the contrary, in the bulk of the particle.

In this work, a comparative analysis of the properties of glass fiber-reinforced epoxy resin (ED-20) composites and composites based on glass fiber-reinforced phosphorus-containing ester methacrylate oligomers (PEAO) was carried out. Reinforced fiberglass plastics made on the basis of PEAO have demonstrated promising fireproof characteristics, especially in limited oxygen index and smoke emission tests. It is also worth noting that the mechanical properties of materials based on phosphorus-containing ester-acrylate resins are outstanding. The samples of a widely used glass fiber reinforced epoxy resin ED-20 with 9,10-dihydro-9-hydroxy-10-phosphaphenanthrene-10-oxide-4,4`-diaminodiphenylmethane (DDM-DOPO) additive demonstrated lower flammability compared to the samples without fire retardant additives. A mixture of DDM-DOPO and graphene added to the samples led to a low smoke generation rate of the samples; however, the rate was 1.5-2 times higher than that of the samples based on phosphorus-containing ester methacrylate resins. The addition of fire retardants has reduced the mechanical properties of fiberglass plastics based on epoxy resin, which can be a problem for the use of these materials in the aviation industry. These results clearly show better prospects of using fiberglass-reinforced plastics based on phosphorus-containing ester methacrylate oligomers in comparison with modified plastics based on the widely used epoxy resin.

A technique is proposed for determining the dielectric properties of water in a nanoscale layer at frequencies corresponding to orientation polarization. The method is based on the registration of the change in the velocity of elastic surface waves resulting from the interaction with a thin layer of a liquid. It was assumed that the dispersion of the dielectric permittivity of water in the thin layer is described by the Debye's equations of dielectric relaxation. In order to demonstrate the capabilities of the proposed method, the values of the real part of the dielectric permittivity of adsorbed water at various frequencies f (43.2; 64.8; 108; 129.6, 194.4, 302.4, 388.8 MHz) were experimentally determined at a fixed thickness of the adsorption layer h (2.2; 2.8; 3.7; 13 nm). The determination of the value of the imaginary part of the dielectric permittivity as well as the calculation of the time of dielectric relaxation, static, and high-frequency dielectric permittivities was enabled by the use of the experimental values and Debye's equations. A comparison was made between the dielectric properties of adsorbed water and those of water in the bulk liquid phase. The high-frequency dielectric permittivity of adsorbed water was found to be lower than that of water in the bulk liquid phase, while the static dielectric permittivity was significantly higher. The dielectric relaxation time of adsorbed water is dependent on the thickness of the adsorption layer and is significantly longer than that of water in the bulk liquid phase.
Testing of industrial oil I-20A with nanodispersed additives of shungite and serpentine on a friction machine
Authors:   Udmurt Federal Research Center UB RAS, Zhirov Dmitriy K.
Published: April 2024

The paper presents the results of the experiments on the introduction of shungite and serpentine into industrial oil I-20A and the assessment of the friction coefficient in the load range of 50-200 N. The analysis of the results on the influence of the oil - shungite - serpentine ratios show that at the above loads the minimum friction coefficient is achieved when 0.9 % serpentine and 0.4 % shungite have been added to industrial oil I-20A. In this case, a reduction in the coefficient of friction by 25 % is obtained in comparison with the base industrial oil I-20A. The studies of the shungite powders and serpentine before grinding were carried out using a Thermo Fisher Scientific Quattro S scanning electron microscope. The microanalysis of the samples of shungite and serpentine studied in this work showed the presence of distinct particles with different compositions in them; this is often observed in minerals. The shungite sample contains a lot of iron, silicon, aluminum and potassium. To use shungite and serpentine obtained from other deposits as oil additives, additional studies of specific samples should be carried out.
La louve et le lion. La métaphore animale dans les romans en prose français
Authors: Trachsler Richard
Published: April 2024

Dans cette vaste opération de mise en place d’un univers ordonné et compréhensible que constitue la littérature arthurienne, la métaphore animalière joue un rôle important, dans la mesure où elle sert à montrer ce qui, par définition, est invisible : à l’aide d’animaux comme la louve, le renard ou le lion, elle entend faire entrevoir l’avenir tout en permettant de voir à l’oeuvre, par la même occasion, le monde surnaturel qui se manifeste au sein du nôtre par le truchement de prophéties et de songes. Les deux discours, prophétique et onirique, convergent et les métaphores, à la fois motivées et stables, forment la condition nécessaire à la création d’un univers intelligible.
‘Darkness at the Beginning’: Chance in Raymond Chandler’s and Dashiell Hammett’s Novels
Authors: Boof-Vermesse Isabelle
Published: April 2024

Detective fiction and metaphysics have often been brought together for their analogous speculative drive towards the original cause. Drawing on Siegfried Kracauer’s analysis of classical detective stories as delineating the limits of ratio even as it celebrates its powers, thus inadvertently conceding man’s finitude, this essay claims that the treatment of chance in American hard-boiled fiction manifests its Gnostic underpinnings. Simultaneously, evidence of the fact that the world is ruled by contingency and the symptom of some malevolent agency at work, chance, as noted by Quentin Meillassoux, is also a negative absolute that, in its purest form, escapes all forms of human modelling and thus allows us to catch a glimpse at the real, lying beyond what is apprehended by our categories. Raymond Chandler’s The Big Sleep (1939) devotes special attention to chance: dramatic roulette scenes taking place at a casino, resolutions relying on coincidence, mechanistic metaphors exposing human beings as defective puppets or botched jobs – all point to an obscure place, something darker than the enigma set up by the case, and they activate a sense of the numinous. The Maltese Falcon (1930) by Dashiell Hammett openly nods at Charles Peirce’s doctrine of chance (tychism) in a most enigmatic embedded anecdote known to aficionados as ‘the Flitcraft parable’, a tale that shows how chance is recuperated by determinism in the guise of habit. Here also a form of Gnostic influence, if only by parodically gesturing towards the Puritan doctrine of election, can be detected in the novel, beyond the narrative interpretation of the story (a cautionary tale from the detective to the culprit) generally adopted by commentators.
Thriller juif et pilpul : quand la Kabbale s’invite au sein du noir
Authors: Casta Isabelle Rachel
Published: April 2024

Il y a, si l’on y songe, une quasi-synonymie, ou au moins un riche liage intersémiotique, entre les mécanismes de la pensée vétérotestamentaire et la dramaturgie du thriller. Tout se passe un peu comme si les romans policiers, juifs ou non, servaient de gigantesques fan fiction au texte biblique premier. Pour mieux saisir encore les raffinements d’une culture entièrement portée vers la résolution des mystères (du monde, du crime, ou bien de l’élection) on pourrait se pencher sur l’oeuvre de quelques grands auteurs policiers de tradition juive (Guy Konopnicki, Harry Kemelman, Dror Mishani) pour scruter comment ils réarticulent les enseignements du pilpul avec les étapes nécessaires des enquêtes criminelles. Doutes, hésitations et tergiversations finissent toujours par aboutir à la résolution « humaine » de l’intrigue. Mais est-ce suffisant ? Pas toujours, selon le Solitaire de Prague : « Il y a surabondance d’espoir, mais rien pour nous ».

Análise da avaliação de capacidade técnica para o manuseio e porte de arma de fogo na Polícia Militar de Mato Grosso do Sul
Authors: BORGES Roger Fabien Pereira
Published: April 2024

Este artigo tem como objetivo analisar e refletir sobre o processo de avaliação da capacidade técnica do policial militar para o manuseio da arma de fogo. A metodologia de pesquisa utilizada é bibliográfica e documental que, fundamentada em legislações, manuais e literaturas sobre estudos realizados acerca o tema, aborda questões da utilização da arma de fogo e sua empregabilidade. Como resultado da análise das legislações federais e dos atos normativos da Polícia Militar de Mato Grosso do Sul, conclui-se que o policial militar necessita ser submetido a uma criteriosa avaliação de capacidade técnica para o manuseio deste instrumento e desse modo, atingir de forma satisfatória o domínio do armamento que deve estar pautado na preservação da vida, na aplicação da lei e na defesa da sociedade. Neste contexto, o processo de ensino de formação do policial militar necessita ser elaborado dentro de parâmetros objetivos, com a edição de normativas internas e, ainda, contemplar procedimentos como: normas de segurança; noções básicas dos componentes das armas, do seu sistema de funcionamento e da habilidade de tiro; além de proporcionar de forma simulada as mais recorrentes ocorrências policiais com o emprego da arma.
Historie er et redegørelsesfag
Authors: Knudsen Heidi Eskelund
Published: April 2024

Historie som skolefag kan beskrives fra mange vinkler. Observerer man gennem længere tid historieundervisning og elevers skriftlige opgaver i faget, ser man, at faget bl.a. lader sig beskrive som et redegørelsesfag i både grundskolernes og gymnasiernes historieundervisning.

Umiddelbart klinger betegnelsen ”redegørelsesfag” måske lidt negativt, men som artiklen her fremhæver, afhænger det af hvorledes man vælger at forstå, hvad ”redegørelse” egentlig vil sige. En pointe i artiklen er, at netop forståelsen af redegørelse i historiefaget er vigtig – dels for den faglige selvforståelse hos de som praktiserer faget, dels og i forlængelse heraf for fagets og undervisningens arbejde med diverse faglige mål vedrørende elevers dannelse, udvikling og kompetencer. Artiklen fremhæver to tilgange til redegørelse.
Ægte død og ødelæggelse – Minecraft og historiske scenarier
Authors: Johannesen Hildegunn Juulsgaard
Published: April 2024

Byg op og bryd ned. Minecraft tilbyder 3D genererede verdener, hvor der kan bygges, udforskes, samles, skabes og kæmpes. Elever fra Ahlmann-skolen i Sønderborg deltog i et utraditionelt undervisningsforløb om 1864 på Bibliotek Sønderborg, bygget og fortalt gennem Minecraft. Forløbet var et led i at styrke og kvalificere samarbejde og netværk i den åbne skole.

Formålet med denne artikel er at præsentere nogle didaktiske refleksioner over, hvordan man kan arbejde med computerspil i den åbne skole gennem samarbejde på tværs af institutioner.

Artiklen vil først rette fokus mod, hvorfor og hvordan spil kan virke motiverende i Historieundervisningen og bidrage til elevernes scenariekompetencer.

Herefter ser artiklen på, hvordan samspillet mellem kulturinstitutioner, uddannelsesinstitutioner og skole, kræver indsigt i hinandens virkeligheder men også respekt for at inddrage de forskellige fagligheder på forskellige tidspunkter i løbet af en samarbejdsperiode.

Desuden vil der gennem eksempler fra et praksissamarbejde mellem Biblioteket Sønderborg, Museum Sønderjylland – Sønderborg Slot, Ahlmannsskolen, Sønderborg Kommune og UC SYD, blive diskuteret, hvordan et fokus på det motiverende og kreative læringsrum kan være med til at styrke aktiviteter og læreprocesser i den åbne skole.
Samarbejde og faglig progression i historiefaget mellem grundskole og gymnasium
Authors: Knudsen Heidi Eskelund
Published: April 2024

Der ligger i overgangen mellem grundskole og gymnasium et uudnyttet potentiale, hvad angår fagligt samarbejde og didaktisk udveksling mellem historielærere. At det forholder sig således bliver særligt tydeligt, når man fokuserer på spørgsmålet om faglig progression. Artiklen problematiserer, at faglig progression ofte forbindes mere med historiefagets kronologi end med spørgsmålet om elevers kognitive bevægelser mellem vidensniveauer af gradvist stigende kompleksitet.

Published: April 2024

Traditionelt har der været en opdeling mellem humaniora og naturfag. I skolefaget historie er det da heller ikke almindeligt at beskæftige sig med miljøproblemer og klimaudfordringer. Men vi lever i, hvad der betegnes som den antropocæne epoke, hvor mennesket er den helt afgørende faktor for Jordens udvikling. Derfor må man også i historie beskæftige sig med disse udfordringer. Det gør Bo Fritzbøger (KU) rede for i sin artikel Nutidens klimaforandringer som historiefagligt problem.
The journey of the developing sport psychologist -'Navigating the applied lowlands and limitations of our language'
Authors:   , Lindsay Peter James
Published: April 2024

There is a growing body of literature exploring the early development of sport psychology consultants (Collins, Evans-Jones, & O’Connor, 2013; Tod & Bond, 2010). However, there remains limited exploration of the longitudinal development of practitioners, an area which may provide important insights relevant for both training and education. Rønnestad and Skovolt’s (2003) sixstage practitioner development framework can be applied to the development of sport psychologists, each maturing at different rates and at times regressing through stages (Tod, 2007). Via six discrete published works this thesis details the author’s development as a practitioner over a 15-year period. Each publication is characterized by a stage of development, highlighting significant sources of influence, both professionally and personally. Study one details the author’s initial professional philosophy, grounded in the dominant western approach of CBT (Holt & Strean, 2001) and characterized as by a ‘layhelper’ and ‘beginning student’ phase. This philosophy shifted towards person-centered and briefer approaches as the author progressed through ‘advanced student’ and ‘novice professional’ phases, as detailed within studies two and three. Study four, an autoethnographic account, explored the challenges experienced by the author as a resident psychologist during a televised sporting event, characterized by the shift from ‘novice practitioner’ to ‘experienced practitioner’. Study 5 highlighted a shift in professional philosophy driven by an exploration of the philosophical writings underpinning brief therapeutic approaches. Finally, study six explored the development of a professional philosophy encompassing beliefs about the discipline as a whole and its role in supporting performers. Through a greater understanding of the journey from ‘lay helper’ to ‘senior practitioner’, the thesis highlights a range of areas for consideration by neophyte, mid-career and experienced practitioners. The thesis highlights the confusing and frustrating nature of development, highlighting that such feelings are natural and helpful to the development of skilled applied practitioners.
The importance of geographical location to people who have experienced homelessness
Authors:   , Anderson Paul M
Published: April 2024

Recently, the number of people experiencing homelessness moving to unfamiliar geographical locations to secure accommodation has increased. One impact of Covid-19 lockdown was movements of people sleeping rough into emergency accommodation in new locations. This research investigated the importance of location to people who have experienced homelessness, and their agency around it; subjects, on which, little academic literature exists. The temporary relocation of people experiencing rough sleeping into hotels created opportunities to research their experiences. The largely inductive methods chosen, involved qualitative interviews with this group and with a smaller group of people in more settled accommodation. Data was supplemented by 10 qualitative interviews with other key stakeholders. Also, a short questionnaire was completed by 104 people in various other Covid-19 emergency accommodation. Data was analysed using the writings of Bauman on the plight of the poorest within neoliberalism. Innovatively, the research told the lived experience stories of people who had recently slept rough and moved to temporary accommodation. The findings show both they, and people who had previously experienced homelessness, value a number of aspects of location such as existing social contacts and work opportunities. However, many feel they have little chance of actualising these preferences.. The contributions to academic knowledge can be summarised thus: 1. People experiencing homelessness have needs and wants around location 2. The practical relationship they have with relocation is often best understood in terms of displacement rather than attachment or ambivalence. 3. Their needs and wants around location often clash with the reality of displacement 11 4. Agencies trying to help people experiencing homelessness, feel like they are operating in a structural straitjacket created by a lack of resources. This limits the support they can provide 5. Bauman’s analysis helps identify the covert mechanisms by which people experiencing homelessness are displaced and excluded from locations in neoliberal societies. 6. Largely inductive methods are particularly valuable in drawing-out and understanding the experiences of people experiencing homelessness 7. Conducting research with people who have experienced homelessness without face-to-face contact is possible, but there are drawbacks, including methodological limitations and complex ethical questions.
The Chesterfield Accent and Dialect: Borderland Identity, Perceptions and Production.
Authors:   , Ashmore Claire
Published: April 2024

This thesis is a first wave (Eckert, 2012) sociolinguistic study that presents perceptions of East Midland and South Yorkshire accents and dialects from the perspective of three generations of Chesterfield locals. Chesterfield is a town in North East Derbyshire, England, close to several administrative, perceptual, and linguistic borders: Derbyshire and Yorkshire, the Midlands and the North; GOAT and FACE monophthongal and/or diphthongal realisations. As such, Chesterfield is regarded as a border town, with the identity of Chesterfield locals hypothesised to be either ‘hybrid’ (Llamas, 2010: 235-6) or affected by a ‘heightened diversity’ (Britain, 2010: 200) due to its close geographical proximity with Sheffield, South Yorkshire. This study analyes the results of dialect recognition tasks that elicited how East Midland and Sheffield voices are indexed (Silverstein, 2003) to a largely Chesterfield audience. The same respondents were asked to position lines on a map task which asked for the placement of a North/South and potentially Midland dividing line in England to better understand regional identity from an East Midland location. These data are then compared against the same respondents’ word list data in order to comprehend more about the realisation of the GOAT and FACE vowels in Chesterfield across three generations, where the literature had previously understood both vowels to be more dipthongal in Chesterfield and more monophthongal in Sheffield (Finnegan, 2011). These data are interpreted using both qualitative and quantitative techniques, which suggest age could be a key variable both in dialect recognition and GOAT and FACE linguistic production in Chesterfield. A ‘scale of northern-ness’ is proposed to be instrumental in the placement of local voices, where the Midlands is understood to be a transition zone from northern to southern linguistic features by non-linguists. With historical rivalry and political differences between Chesterfield and South Derbyshire/Nottinghamshire still evident, Chesterfield appears to be northward facing despite the enduring wish to remain administratively separate from Sheffield.
Da dialética entre trabalho pedagógico pesquisado e realizado

A pesquisa se debruça sobre a biografia acadêmica de Liliana Soares Ferreira. A Professora, atualmente vinculada à Universidade Federal de Santa Maria, como professora titular, possui uma vasta contribuição no ensino, na pesquisa e extensão, bem como descreveu um(uma) conceito(categoria) de trabalho pedagógico, retroalimentando a comunidade acadêmica na produção do conhecimento na contemporaneidade. Para tanto, objetivou-se narrar e refletir sobre a trajetória na produção acadêmica, da pesquisadora em Educação brasileira, Liliana Soares Ferreira. Desenvolveu-se o estudo teórico-metodologicamente, como uma espécie de metaexplicação, com base na Análise dos Movimentos de Sentidos (AMS), a partir das técnicas da pesquisa bibliográfica e da análise documental. A pesquisa bibliográfica se ocupou de autores(as) que estudam as temáticas abordadas neste artigo e da produção científica da Professora; a documental foi realizada com a análise do currículo da autora na Plataforma Lattes, visualização dos movimentos de sentidos das categorias por ela desenvolvidas, sobretudo, “trabalho pedagógico”, nos textos publicados entre 2019 e 2023. Como técnica de análise dos dados produzidos, aplicou-se a própria AMS. Constata-se, ao narrar e analisar a biografia acadêmica de Liliana, que a pesquisadora elaborou o(a) conceito(categoria) trabalho pedagógico e, a partir dele(a), identificou-se alguns sentidos da dialética entre o trabalho pedagógico pesquisado e o trabalho pedagógico realizado, cujos movimentos entremeados justificam e potencializam a sua trajetória, na (com)vivência com outras(os) sujeitos.
escolaridade dos pais dos estudantes da educação de jovens e adultos em debate
Authors: Ferreira Luís Carlos
Published: April 2024

O propósito do texto é analisar a relação do nível de escolaridade dos pais dos estudantes matriculados na educação de jovens e adultos e as possíveis influências reveladas no processo de retorno às salas de aula da modalidade. A abordagem intergeracional e interdisciplinar dessa discussão, desperta interesse de entender se existe [ou não] relação entre a escolaridade dos pais com a situação dos estudantes, os quais, por razões diversas, deixaram de dar continuidade aos estudos na idade esperada, mas retornaram às salas de aula em busca de aprendizagem, formação e certificação escolar. A base teórica procede de Bourdieu (2003), DaMatta (2002), Castel (2010), Freire (1987) e Escóssia (2021) cujos processos de formação escolar e humana passam pela força do papel com a certificação e a apreensão dos conhecimentos como instrumentos de emancipação do indivíduo. A pesquisa qualitativa, do tipo participante, permitiu a interlocução feita in loco, com 33 (trinta e três) estudantes do ensino fundamental de uma escola pública, da EJA, no interior do estado do Ceará, em conversas gravadas em áudio, com base em três perguntas que pautaram a análise nas falas dos estudantes-respondentes. Diante dos achados no estudo, foi possível verificar a necessidade de superação das histórias familiares de insucesso escolar conduzidas a uma não repetição dessa trajetória intergeracional; a prospecção de um futuro possível mediante a certificação alcançada na conclusão da etapa escolar e, por fim, as chances de mobilidade social prometida com a certificação, convertida em melhores oportunidades profissionais associadas à transformação social.
Algumas considerações sobre o Philosophiae Doctor e o plágio acadêmico
Authors: Alves Francisco Regis Vieira
Published: April 2024

A integridade, boas práticas e condutas na pesquisa se constituem, hodiernamente, cada vez mais arraigadas e integrantes de uma atitude acadêmica responsável. No lócus acadêmico uma pesquisa de doutorado, por exemplo, não pode prescindir de fatores de ordem do ineditismo e que asseveram uma pesquisa original. Nesses termos, o presente trabalho discute a noção de plágio, sem negligenciar elementos de gênese e evolução ao decurso dos últimos séculos e novas políticas de prevenção científica. Ademais, atendo-se ao exame do papel do Philosophiae Doctor (PhD), discute também novas modalidades emergentes de pesquisa, como, por exemplo, o caso do (PhDP) por publicação. Finalmente, o trabalho ampara uma compreensão não trivial entre categorias emergentes de manifestação do plagio, diante de relações acadêmicas não estáticas e características de uma pesquisa de doutorado.

Published: April 2024

Este artigo discute os avanços da Análise de Conteúdo nas pesquisas educacionais, a partir de uma pesquisa do tipo bibliográfica e documental que busca apresentar esta técnica, realizada com o auxílio do software Atlas.ti. Foram considerados dados recuperados em dois estudos desenvolvidos por um laboratório de pesquisas sobre inclusão em educação. Partiu-se do pressuposto de que a abordagem favorece as pesquisas e problematizou-se se e como um recurso tecnológico pode contribuir nas respectivas análises. Além de duas publicações, o artigo apresenta documentos desenvolvidos no processo de investigação, geradores dos resultados nos estudos. Demonstra, ainda, o percurso empreendido e propõe o uso da técnica com o auxílio do software, já que foi evidenciada uma maior eficácia no tratamento dos dados, o que permitiu inferências quanto aos avanços em pesquisas com essa perspectiva, embora tenham sido trazidas ressalvas quanto ao papel preponderante dos pesquisadores durante esse empreendimento.

Trajetórias cruzadas de vida, profissão e militância
Authors: Agapito Juliano , Simionato Margareth Fadanelli , Hobold Márcia de Souza
Published: April 2024

A formação de professores no Brasil historicamente tem sido perpassada por projetos de sociedade em disputa. Essa contenda propõe a formação de professores de acordo com seus princípios, ou seja, por um lado, um projeto pragmático voltado à preparação de mão de obra para o trabalho e, de outro, um projeto que busca o desenvolvimento omnilateral do ser humano, pautado em uma formação pelo trabalho como construtor e produtor da própria existência. Os pressupostos ideológicos e epistemológicos que sustentam a formação docente se alternam, por vezes, configurando contradições epistêmicas e ideológicas; por outras, convergindo em consensos e negociações. Nesse artigo, entrevistamos a Professora Doutora Vera Bazzo, expoente da educação brasileira e atuante na luta por um projeto de sociedade que defende uma educação pública, laica e de qualidade social para todos e todas. Em sua fala potente, sua militância e veia de luta por uma sociedade democrática e uma educação para todos e todas perpassam sua história de vida pessoal, acadêmica e profissional, sendo a tônica de suas ações, politizações e reações aos momentos vividos e impostos em períodos de maior, menor ou total ausência de liberdade democrática. Nesse sentido, a constituição de sua trajetória profissional é enlaçada por uma curiosidade epistêmica constante e um senso de justiça social aguçado.
