The Interaction of Dynamic Cerebral Autoregulation and Neurovascular
Coupling in Cognitive Impairment
Authors: Beishon Lucy C. , Intharakham Kannakorn , Haunton Victoria J. , Robinson Thompson G. , Panerai Ronney B.
Published: January 2022

Background:

Dynamic cerebral autoregulation (dCA) remains intact in both ageing and
dementia, but studies of neurovascular coupling (NVC) have produced mixed findings.

Objective:

We investigated the effects of task-activation on dCA in healthy older adults (HOA),
and patients with mild cognitive impairment (MCI) and Alzheimer’s Disease (AD).

Methods:

Resting and task-activated data from thirty HOA, twenty-two MCI, and thirty-four AD
were extracted from a database. The autoregulation index (ARI) was determined at rest and during
five cognitive tasks from transfer function analysis. NVC responses were present where group-specific
thresholds of cross-correlation peak function and variance ratio were exceeded. Cumulative response
rate (CRR) was the total number of positive responses across five tasks and two hemispheres.

Results:

ARI differed between groups in dominant (p=0.012) and non-dominant (p=0.042) hemispheres
at rest but not during task-activation (p=0.33). ARI decreased during language and memory
tasks in HOA (p=0.002) but not in MCI or AD (p=0.40). There was a significant positive correlation
between baseline ARI and CRR in all groups (r=0.26, p=0.018), but not within sub-groups.

Conclusion:

dCA efficiency was reduced in task-activation in healthy but not cognitively impaired
participants. These results indicate differences in neurovascular processing in healthy older adults
relative to cognitively impaired individuals.
Blood Pressure Responses in Firefighters: A Review
Authors: Feairheller Deborah L , McMorrow Carly
Published: January 2022

Blood pressure (BP) responses are controlled by various factors and understanding how
BP changes is important to occupational health. This paper presents a review of the literature that
reports BP responses in the firefighter population. Hypertension is one of the main risk factors underlying
the pathophysiology of cardiovascular disease (CVD), and cardiac incidents remain the
leading cause of line-of-duty deaths in firefighters. Risk factors for line-of-duty deaths include obesity,
previous or underlying heart disease, and hypertension. The occupation of firefighting is one
of the most hazardous and dangerous jobs, yet over 50 % of firefighters are volunteers. Tactical operations
and the hazardous nature of firefighting are exposures that influence stress responses and,
therefore, affect BP. In fact, hypertension in firefighters often remains undocumented or undiagnosed.
CVD risk and elevated BP in tactical populations, like firefighters, maybe a combination of
physical and emotional stress due to the nature of the job. Cross-sectional studies have reported
that firefighters have higher levels of BP and higher rates of hypertension compared to civilians. Interestingly,
there is a limited amount of research that reports BP values before and after firefighting-
related activities, and very few studies on interventional changes in BP. Here, we synthesize
the literature on firefighting and provide a summary of the studies that report pre- and post- BP levels
that relate to CVD risk factors, occupational factors, firefighting activities, and the data on exercise
training and BP. More studies are needed that examine BP in firefighters and report on the
changes in BP with occupational activities.
Recent Patents on Petroleum Pipe Inspection Gauge in China
Authors: Chen Zhong , Qiu Xiaoyang , Yang Lingling , Wang Yalin
Published: January 2022

Background:

As the demand for petroleum products grows, pipes to carry these products
are also required extensively. Consequently, petroleum pipe blockage has become a frequent and
severe problem in China. In order to ensure trouble-free operation, it is necessary to clean and inspect
the petroleum pipe regularly. However, currently available petroleum pipe inspection gauges
can block the petroleum pipe easily, and their cleaning efficiency is not as high as desired. Therefore,
mechanisms to prevent pipe blockage and ensure high-efficiency cleaning are being given
much importance in studies on petroleum pipe inspection gauges.

Objective:

The aim of the study is to review recent patents related to petroleum pipe inspection
gauges in China and forecast possible designs that can mitigate present-day problems associated
with petroleum pipe inspection gauges.

Methods:

This paper has studied and compared various representative patents relevant to the petroleum
pipe inspection gauge.

Results:

A large number of patents filed in China related to petroleum pipe inspection gauges have
been studied and the anti-blocking mechanism as well as the cleaning efficiency of the petroleum
pipe inspection gauges described in those patents have been analyzed and compared. Forecasts were
made regarding the possible development trajectories in the design of petroleum pipe inspection
gauges.

Conclusion:

The problems of easy blockage and poor cleaning efficiency are yet unsolved for petroleum
pipe inspection gauges. It is expected that future work will focus on the development of
pigging, new materials, power sources, and intelligent control to resolve these issues.

Published: January 2022

Stigma develops from places that are vulnerable to the spread of COVID-19. Stigma has an impact on socio-psychological conditions that cause mass complaints. This stigma causes people to feel panicked and eventually leads to paranoia. In accordance with the development of conditions related to COVID-19, this study aims to analyze the pattern of developing stigma and its anticipation pattern through the formation of collective solidarity. This research uses a mixed method approach. Data were analyzed and supported using SPSS 16 and Nvivo 12. Includes elements of social stigma, collective solidarity, anxiety, and attitudes to vaccines. The results show that there are several effects of stigma such as health risks, exclusion, anxiety, life discomfort, psychological disorders, reduced social and emotional capital, breaking of family ties and social solidarity that work as barriers to social welfare. The relationship between stigma and collective solidarity in this research is to fight misconceptions, misinformation and stigmatization, in which community members directly support each other, become volunteers, compose songs about COVID, hold lecture on the wisdom during the pandemic, and present humor that can strengthen the community and reduce the level of stigmatization in COVID-19 patients. In the formation of collective solidarity, namely using sympathetic narratives, communication methods that provide motivation to heal, mutually reinforcing attitudes, donation and sharing movements, strengthening social sensitivity, as well as active involvement of the private and public sectors. In the private and public sectors, especially for hospitals, this is done by allocating the state budget and providing better health management.

Using the methods of X-ray diffraction and scanning electron microscopy, the structure of composite films based on chitosan and single-wall carbon tubes has been studied. It is shown that the introduction of carbon nanotubes leads to the ordering of the chitosan structure. Increase in concentration of nanotubes (from 0 to 3%) causes rise in the value of storage modulus from 3 to 4 GPa (DMA data), increase in electrical conductivity of samples (from 10-11 to 102 S/m), and some changes in their dielectric permittivity (from 5.5. to 26 at an electrical field frequency of 1kHz). Data on the ionic and electronic components of the conductivity of the composite film are presented.
Механизм термической ионизации уротропина на поверхности интерметаллида NaAu-=SUB=-x-=/SUB=-

Published: January 2022

Thermal ionization of methenamine (C6H12N4) on the surface of the NaAux intermetallic compound has been studied. It has been established that the processes of decomposition, desorption and ionization of adsorbed compounds, thermally stimulated on the surface, proceed due to the accumulation of energy at the degrees of freedom of the adsorption complex, including the adsorbed compound and a solid, by the mechanism of monomolecular decomposition reactions. In this case, the decomposition of the adsorption complex is accompanied by the desorption of ions that are not in thermal equilibrium with the solid. The uniformity of the temperature dependences of the ion current and their distribution over two groups allowed us to conclude that ions are desorbed from the surface, which correspond to the decays of individual adsorbed molecules, as well as the decays of dimers formed on the surface. The decay of methenamine molecules during thermal ionization occurs in the same way as their decay in vacuum during electron ionization, which indicates the preservation of the bulk structure of methenamine molecules during adsorption and a significant lifetime of the excited state of compounds on NaAux.

Authors: Jiang Nan , Rogers Erin S , Cupertino Paula , Zhao Xiaoquan , Cartujano-Barrera Francisco , Lyu Joanne Chen , Hu Lu , Sherman Scott E
Published: January 2022

BACKGROUND

Smoking remains a major public health issue among Chinese immigrants. Smoking cessation programs that focus on this population are scarce and have a limited population-level impact due to their low reach. Mobile messaging interventions have the potential to reach large audiences and expand smokers’ access to smoking cessation treatment.

OBJECTIVE

This study describes the development of a culturally and linguistically appropriate mobile messaging smoking cessation intervention for Chinese immigrant smokers delivered via WeChat, the most frequently used social media platform among Chinese people globally.

METHODS

This study had 2 phases. In phase 1, we developed a mobile message library based on social cognitive theory and the US Clinical Practice Guidelines for Treating Tobacco Use and Dependence. We culturally adapted messages from 2 social cognitive theory-based text messaging smoking cessation programs (SmokefreeTXT and Decídetexto). We also developed new messages targeting smokers who were not ready to quit smoking and novel content addressing Chinese immigrant smokers’ barriers to quitting and common misconceptions related to willpower and nicotine replacement therapy. In phase 2, we conducted in-depth interviews with 20 Chinese immigrant smokers (including 7 women) in New York City between July and August 2021. The interviews explored the participants’ smoking and quitting experiences followed by assessment of the text messages. Participants reviewed 17 text messages (6 educational messages, 3 self-efficacy messages, and 8 skill messages) via WeChat and rated to what extent the messages enhanced their motivation to quit, promoted confidence in quitting, and increased awareness about quitting strategies. The interviews sought feedback on poorly rated messages, explored participant preferences for content, length, and format, discussed their concerns with WeChat cessation intervention, and solicited recommendations for frequency and timing of messages.

RESULTS

Overall, participants reported that the messages enhanced their motivation to quit, offered encouragement, and made them more informed about how to quit. Participants particularly liked the messages about the harms of smoking and strategies for quitting. They reported barriers to applying some of the quitting strategies, including coping with stress and staying abstinent at work. Participants expressed strong interest in the WeChat mobile messaging cessation intervention and commented on its potential to expand their access to smoking cessation treatment.

CONCLUSIONS

Mobile messages are well accepted by Chinese immigrant smokers. Research is needed to assess the feasibility, acceptability, and efficacy of WeChat mobile messaging smoking cessation interventions for promoting abstinence among Chinese immigrant smokers.

Published: January 2022

Amylolytic bacteria are a source of amylase, which is an essential enzyme to support microalgae growth in the bioreactor for microalgae culture. In a previous study, the highest bacterial isolate to hydrolyze amylum (namely PAS) was successfully isolated from Ranu Pani, Indonesia, and it was identified as Bacillus amyloliquefaciens. That bacterial isolate (B. amyloliquefaciens PAS) also has been proven to accelerate Chlorella vulgaris growth in the mini bioreactor. This study aims to detect, isolate, and characterize the PAS’s α‐amylase encoding gene. This study was conducted with DNA extraction, amplification of α‐amylase gene with polymerase chain reaction (PCR) method with the specific primers, DNA sequencing, phylogenetic tree construction, and protein modeling. The result showed that α‐amylase was successfully detected in PAS bacterial isolate. The α‐amylase DNA fragment was obtained 1,468 bp and that translated sequence has an identity of about 98.3% compared to the B. amylolyquefaciens α‐amylase 3BH4 in the Protein Data Bank (PDB). The predicted 3D protein model of the PAS’s α‐amylase encoding gene has amino acid variations that predicted affect the protein’s structure in the small region. This research will be useful for further research to produce recombinant α‐amylase.

Published: January 2022

Application of high levels of chemical fertilizers for optimal growth of sweet sorghum causes environmental degradation. Plant growth‐promoting bacteria have biotechnological importance because they can improve the growth and health of important agronomic plants. This study aimed to isolate, characterize, and identify endophytic bacteria associated with sweet sorghum (cv. KCS105), and also to study the inoculation effects of selected isolates on sorghum growth. In this study, 35 isolates were evaluated for their ability to support plant growth. The results showed that seven isolates were diazotrophic, six were capable of dissolving phosphate, six produced IAA and could detect ACC‐deaminase activity, and three inhibited the growth of pathogenic fungi. Nine isolates exhibiting mechanisms for promoting plant growth from the Alphaproteobacteria (Devosia), Firmicutes (Bacillus, Paenibacillus, Staphylococcus), and Actinobacteria (Microbacterium, Brachybacterium) phyla were identified. In addition, the Paenibacillus sp. BB7, Bacillus sp. PIB1B, and Bacillus sp. PLB1B isolates showed increasing effects on plant growth in greenhouse tests. Endophytic bacterial isolates which display plant growth‐promoting features can potentially be employed as biofertilizer agents. They may also address environmental damage problems resulting from the use of chemical fertilizers and pesticides.

Depletion of resources such as forestry, minerals etc. and resource-based industries such as wood and paper etc., due to rising pollution, is one of the biggest challenges which the humankind is facing today. In this paper, a mathematical model has been designed to give an insight into the effect of pollutants on natural resources which in turn affects the growth and stability of industries dependent on such biomass. The model is analyzed using stability theory of differential equations. Five dependent variables are considered in the model and some important assumptions are made. Two equilibria are found in the equilibrium analysis and conditions of local and global stability of interior equilibrium are obtained. Numerical simulation is also done to demonstrate the analytical findings. It is found in the study that as we impose an environmental tax on the polluters, the concentration of pollutants in the environment is controlled and the stable equilibrium shifts in such a way that the densities of resource biomass and dependent industries are close to the densities which correspond to the pollution free ecosystem.
Presentes historizados. Sentidos sobre el genocidio argentino (1983-2014)
Authors: Silveyra Malena
Published: January 2022

Este artículo analiza los principales modelos explicativos del genocidio argentino (1976-1983) entre 1983 y 2015, entendiendo que las disputas por el sentido del pasado se articulan con el sentido común de la sociedad presente, posibilitando modos particulares de apropiación o ajenización de esas experiencias. Para ello se ha construido la categoría estructura de sentido con el objetivo de dar cuenta del conflicto central en cada narrativa, identificando los distintos elementos que la componen y sus relaciones. En el periodo analizado se identificaron cuatro estructuras de sentido: “dos demonios” y “pacificación”, caracterizadas por una explicación de carácter binario; “genocidio” que propone una historización que trasciende la dictadura militar; y “terrorismo de Estado”, que reformula las dos primeras incorporando elementos de la tercera.

La asertividad de China en los Mares del Sur y del Este de China: acercamiento constructivista

Abstract

This article aims to discuss the issue of China’s assertiveness in the South and East China Seas within the constrictivist framework, as economic (liberalism) and military power (realism) are not sufficient to explain the complexity of the problem. It aims to answer the following question: How does the constructivist approach lend itself to the understanding of China’s assertiveness in the case of the South and the East China Sea territorial disputes? It will also explore the following hypotheses: the victimized identity perception leads China to be assertive in the South China Sea dispute and the perception of Japan’s behavior as aggressive (as in the past) provokes China to be assertive in the East China Sea dispute.

Resumen

El presente artículo tiene como objetivo discutir la cuestión de la asertividad de China en Los Mares del Sur y del Este de China dentro del marco constrictivista, ya que el poder económico (liberalismo) y el poder militar (realismo) no son suficientes para explicar la complejidad del problema. Tiene como objetivo responder a la siguiente pregunta: ¿Cómo se presta el enfoque constructivista a la comprensión de la asertividad de China en el caso de las disputas territoriales del Mar del Este y del Sur de China? También explorará las siguientes hipótesis: la percepción de la identidad victimizada lleva a China a ser asertiva en la disputa del Mar del Sur de China y la percepción de agresividad en el comportamiento de Japón (como en el pasado) provoca que China sea asertiva en la disputa del Mar del Este de China.

Published: January 2022

The importance of having a terrestrial observation satellite consists of the need of governments and private entities to have recent images of a specific area, for the use of cartography, illicit plantations, mining, petroleum deposits, natural disasters, etc. Therefore, having up-to-date images of the national territory should be a priority. This analysis and design of mission focuses on the design of the orbit of the satellite, studying what type of orbit is appropriate for a future Earth observation satellite. The simulation of the orbit is carried out in this work through the study of the perturbations that most affect low-altitude satellites. The calculation of the satellite's revisit time will be based on areas of potential study interest for both the government and private companies settled in the country.

Hepatitis C virus (HCV) is an important contributor to chronic morbidity and mortality in developing countries. The study’s objective was to determine the genotype distribution and risk factors associated with the transmission of HCV infections in pediatric patients. Rapid screening and confirmation by the enzyme-linked immunosorbent assay (ELISA) were used to analyze 585 pediatric blood specimens hospitalized and visited the outpatient department of the largest tertiary care hospital in Pakistan. Detection and genotyping of HCV RNA were performed using a real-time polymerase chain reaction (RT-PCR). Demographic data and a history of risk factors were gathered through a survey questionnaire. HCV RNA was detected in 323 (72.4%) cases which showed viral load ranging from Log10 IU/mL < 3 to > 6 IU/mL. HCV genotype 3a was detected in 256 (79.3%) cases while type 3b and 1a was observed in 36 (11.1%) and 31 (9.6%) patients, respectively. HCV positivity was significantly associated with the cases from rural areas [p = 0.005; odds ratio (OR) 1.65; 95% CI 1.16-2.23] and also significantly associated with low-income group [p < 0.001; OR 5.75; 95% CI 3.90-8.40]. The primary risk factors associated with HCV transmission in children were family history (p = 0.002), blood transfusion (p = 0.03), surgical procedures (p = 0.02), and history of injections (p = 0.05). HCV genotype 3a is the most common genotype in children. The main risk factors for HCV transmission in children are blood transfusion, surgical procedures, and injection practices by informal health care providers.
Evaluation of Cardiovascular Experiment Animal

Published: January 2022

Abstract: In vivo models of myocardial infarction induced by coronary artery ligation in rats usually suffer from high early mortality and a low rate of induction. This study investigated the time course initiation of chronic myocardial infarction in albino rats and the possibility of reducing early mortality rate due to myocardial infarction by modification of the surgical technique. CAL was carried out by passing the suture through the pericardial layer around the midway of the left anterior descending coronary artery including a small area of the myocardium to avoid mechanical damage to the heart geometry. In addition, the role of endothelin-1 in rat heart with congestive heart failure was critically assessed. Time course initiation experiments were designed by sacrificing the animals at different time intervals and by carrying out physiological, biochemical, histopathological, electron microscopical and immunohistochemical studies. Specific markers of myocardial injury, viz. cardiac troponin-T, high sensitivity C-reactive protein, lactate dehydrogenase and fibrinogen were measured at different time points. Serum marker enzymes and activities of lysosomal hydrolases were found to be elevated on the eighth day post-ligation. Histopathological studies demonstrated focal areas showing fibrovascular tissue containing fibroblasts, collagenous ground substance and numerous small capillaries replacing cardiac muscle fibers. Transmission electron micrographs exhibited mitochondrial changes of well-developed irreversible cardiac injury, viz. swelling, disorganization of cristae, appearance of mitochondrial amorphous matrix densities, and significant distortion of muscle fibers and distinct disruption of the intercalated discs. Immune blotting studies confirmed the presence of alpha 2-macroglobulin which supported the inflammatory response. The severity of the CMI was inferred by the measurement of the level of ET-1 in plasma and left ventricle which was significantly higher in the CMI rats than in the sham-operated rats. Immunohistochemical studies at different time intervals showed that there was a significant immunoexpression of ET-1 on the eighth day post-ligation. This study conclusively showed that ligation of left anterior descending artery minimised mortality and ET-1 was expressed during CMI.

Published: January 2022

Abstract: People lost, people missing etc., these are the words we come across whenever there is any mass gathering events going on or in crowded areas. To solve this issue some traditional approaches like announcements are in use. One idea is to identify the person using face recognition and pattern matching techniques. There are several techniques to implement face recognition like extraction of facial features by using the position of eyes, nose, jawbone or skin texture analysis etc., By using these techniques a unique dataset can be created for each human. Here the photograph of the missing person can be used to extract these facial features. After getting the dataset of that individual, by using pattern matching techniques, there is a scope to find the person with same facial features in the crowd images or videos. Keywords: Face-Recognition, Image-Processing, Feature extraction, Video-Processing, Pattern-Matching.

This study aims to examine changes in enterprise management during the COVID-19 pandemic and develop a universal mechanism for managing digital transformation. Its methodological basis is represented by a terminological analysis of the concepts of automation, digitalisation and digital transformation. Their close consideration enables us to form a conceptual scheme of business digitalisation. In sum, the study process shows that full-fledged and fruitful digital transformation can be achieved through restructuring a company’s business process management system. By comparing the outcomes of using digital platform-based business models, the most promising one was selected for use. Its practical application was studied in Azerbaijan, Russia, and Switzerland using the Network Readiness Index (NRI). The analysis made it possible to form business development strategies for each country reviewed and to develop a universal mechanism for digital transformation management by means of optimisation and modelling. The findings suggest that in pandemic settings, digital enterprise management concentrates on survival, self-learning and cooperation without intermediaries through innovation and the transformation of business processes. The strategies can be used to adopt digital technologies and attract investment. Further research can be directed at detailing the proposed mechanism.

Protists represent the majority of the eukaryotic diversity in the
oceans. They have different functions in the marine food web, playing
essential roles in the biogeochemical cycles. Meanwhile the available
data is rich in horizontal and temporal coverage, little is known on
their vertical structuring, particularly below the photic zone. The
present study applies DNA metabarcoding to samples collected over three
years in conjunction with the BATS time-series to assess marine protist
communities in the epipelagic and mesopelagic zones. The protist
community showed a dynamic seasonality in the epipelagic, responding to
hydrographic yearly cycles. Mixotrophic lineages dominated throughout
the year; however, autotrophs bloomed during the rapid transition
between the winter mixing and the stratified summer, and heterotrophs
had their peak at the end of summer, when the base of the thermocline
reaches its deepest depth. Below the photic zone, the community,
dominated by Rhizaria, is depth-stratified and relatively constant
throughout the year, mirroring local hydrographic and biological
features such as the oxygen minimum zone. The results suggest a dynamic
partitioning of the water column, where the niche vertical position for
each community changes throughout the year, likely depending on nutrient
availability, the mixed layer depth, and other hydrographic features.
Finally, the protist community closely followed mesoscale events
(eddies), where the communities mirrored the hydrographic uplift,
raising the deeper communities for hundreds of meters, and compressing
the communities above.
Continuous Monitoring of IgG using Immobilized Fluorescent Reporters

Published: January 2022

In the manufacture of therapeutic monoclonal antibodies (mAbs), the
clarified cell culture fluid is typically loaded onto an initial protein
A affinity capture column. Imperfect mass transfer and loading to
maximum capacity can risk antibody breakthrough and loss of valuable
product, but conservative underloading wastes expensive protein A resin.
In addition, the effects of column fouling and ligand degradation
require the frequent optimization of IgG loading to avoid wastage.
Therefore, continuous real-time monitoring of IgG flowthrough is of
great interest. We previously developed a fluorescence-based monitoring
technology that allows mix-and-read mAb detection in cell culture fluid.
Here we report the use of reporters immobilized on CNBr-activated
Sepharose 4B resin for continuous detection of IgG in column
breakthrough. The column effluent is continuously contacted with
immobilized fluorescein-labeled Fc-binding ligands to produce an
immediately detectable change in fluorescence intensity. The technology
allows rapid and reliable monitoring of IgG in a flowing stream of
clarified cell culture fluid emerging from a Protein A column, without
prior sample preparation. We observed a significant change in
fluorescence intensity at 0.5 g/L human IgG, sufficient to detect a 5%
breakthrough of a 10 g/L load, within 2 minutes at a flow rate of 0.5
mL/min.
Revisiting the role of exchange rate volatility in Turkey’s exports: Evidence from the structural VAR approach
Authors: Barış-Tüzemen Özge , Tüzemen Samet
Published: January 2022

The exchange rate is both an important economic variable when determining a
country?s export volume and an indicator of its international
competitiveness. This paper re-investigates the impact of real exchange rate
volatility on Turkey?s exports using the structural vector autoregression
method and monthly data from 2003:01 to 2019:12. Empirical evidence shows
that real exchange rate and exchange rate volatility do not affect exports in
Turkey. On the other hand, external income has had a slight effect on
Turkey?s exports in the post-global-crisis period. The findings show that
other factors which effect macroeconomic indicators in the Turkish economy
should also be considered.
The Effect of Geographic Distance on Earnings Management Decisions
Authors: Hayes Matthew J. , Mowchan Michael J.
Published: January 2022

Prior research has found evidence that country factors and management styles influence earnings management decisions in various geographic locations. Extending this research, we utilize an experimental setting to isolate the effect of geographic distance on the willingness to manage earnings in a near/distant location. In an initial experiment, we find less acceptable earnings management methods generate greater concerns about the method (ethicality and riskiness) leading to less willingness to manage earnings. Yet, greater geographic distance between the decision-maker and reporting location attenuates these concerns, resulting in increased willingness to use a less acceptable method. In contrast, individuals are willing to use a more acceptable method to manage earnings regardless of geographic distance. These findings are consistent with construal level theory (CLT) and are corroborated in a second experiment where we find that greater geographic distance reduces managers' focus on the means of earnings management, thereby reducing concerns about the method.

Skrivehandlinger og andre handlinger: Design av skriveoppgaver i lærerutdanninga
Authors: Ofte Ingunn , Otnes Hildegunn
Published: January 2022

Studenter i lærerutdanninga forventes å skrive fagdidaktiske tekster på akademisk nivå. I opplæringa av lærerstudentene som akademiske skrivere blir dermed designet av skriveoppdragene viktig, og det er avgjørende hvor presist selve skriveinstruksen er formulert. Artikkelen presenterer en kvalitativ case studie av 19 fagdidaktiske oppgaver fra tolv fagdisipliner og tre lærerutdanningsløp ved en norsk lærerutdanningsinstitusjon. Med utgangspunkt i en forståelse av skriving som en aktivitet utført for visse formål, har vi tatt for oss verbene faglærerne bruker i skriveinstruksene for å indikere ønskede handlinger. Vårt forskningsspørsmål er: Hvilke handlinger blir lærerstudenter bedt om å utføre i arbeidet med fagdidaktiske skriveoppgaver? Analysen viser at studentene blir bedt om å utføre skrivehandlinger på akademisk nivå, men også andre type handlinger knyttet til skriveaktiviteten, både av kognitiv og av mer praktisk art, som er spesifikt retta inn mot lærerprofesjonen. Videre viser analysen at valg av verb er viktig med tanke på tydelighet i oppgaveinstruksene. Vi ser også at visse handlinger er særlig interessante og utfordrende. Især gjelder dette «å reflektere», og vi spør oss om det er en samforent forståelse av dette verbet blant faglærere i lærerutdanninga. Funnene indikerer at det er viktig å rette oppmerksomheten mot hvilke handlinger som skal vektlegges i en fagdidaktisk skriveoppgave i lærerutdanninga og en felles forståelse av hva disse innebærer.
Poesia, corpo e rede na obra de Lenora de Barros
Authors: Bastos Marcus Vinicius Fainer , Arantes Priscila Almeida Cunha
Published: January 2022

O artigo discute a poesia e o corpo como principais materiais na obra de Lenora de Barros, refletindo sobre como a certa altura sua produção se aproxima das práticas de autorrepresentação na cultura em rede. A partir da análise de poemas como Homenagem a George Segal e Poema, o texto reflete sobre a inserção da obra da artista no contexto da poesia visual. Ao abordar Língua Vertebral, No país da língua grande e Procuro-me, entre outros, explora os diálogos com a arte contemporânea. Dessa forma, propõe o entendimento de como a produção de Lenora de Barros transita entre diferentes circuitos. Esta última obra também serve de ponto de partida para pensar o problema da representação de si, conforme ela transita da arte para as redes sociais.
NOMENCLATURA GRAMATICAL BRASILEIRA (NGB) NA ESTEIRA DA HISTÓRIA DAS IDEIAS LINGUÍSTICAS
Authors: Silva Alexandre José
Published: January 2022

Este artigo tem como objetivo tratar, moderadamente, da história acerca do instrumento linguístico (implícito) conhecido como NGB e do impacto dele na historiografia gramatical brasileira. O desenovelar de uma questão-chave – NGB e a produção gramatical – foi posto, a fim de que o ato de historicizar o documento (meta)linguístico não se tornasse um simples ato biobibliográfico. As leituras empreendidas e depreendidas no tocante ao documento oficial se concretizaram na seara dessa questão-chave, tendo, pois, duas vias de historicização: 1) Documento metalinguístico oficial – a história da NGB; 2) Documento oficial e o ensino de gramática. Este trabalho mostra que o processo de (neo)gramatização brasileira vem produzindo um discurso de combate ou um discurso de aceite ao documento, já que no corpo dos instrumentos linguísticos – gramáticas -, surgidos continuamente, o estabelecido pela NGB aparece.
