Finding a home in the public sphere, challenging the social representations of politics: A case study of McGill University’s Women in House Programme, 2001–2005
Authors: Nguyen Chi
Published: September 2023

This paper examines young Canadian women’s conceptions of political power through qualitative interviews with participants of the McGill University’s Women in House Programme, 2001–2005, which documented the women’s first-hand experiences of shadowing women parliamentarians. I examine the female students’ social representations of political power within the Parliamentary process, and notably, how their internalisation of the influence that gender plays in shaping their own interest in engaging in formal politics. In spite of high levels of political knowledge and direct exposure to the political system, these young women continue to accept the dominant political and social discourses that portray them as excluded from the public sphere on the grounds of their gender, age, and in some instances, ethnicity and social class. I also explore how young women conceptualise and understand the social networks, and forms of capital and resources which are associated with access to the elite political community.

Drawing on Nancy Fraser’s theory of subaltern counterpublics, I argue that young women are in need of women-only spaces such as the Women in House programme in order to develop the sites of dialogue and deliberation needed to create counter-discourses that will enable them to challenge the discursive representations of social power within contemporary Canadian political processes. This paper draws on social psychological approaches and makes an important empirical contribution to the political science literature about the engagement and public participation of an under-represented political group.

The climate in the weather (CW) approach, which combines the scientific and everyday sense of climate, has been proposed. The CW is based on the in-depth idea of E. E. Fedorov to classify regional climates as an ensemble of daily weather states. We have transformed this idea into a nonparametric method of processing meteorological series, where each member of the series is mapped to quantiles of corresponding distributions, and then new time series are formed, where meteorological variables are replaced by their quantiles. Next, the members of the new quantized series are combined in weather states. In this work, by using quantiles combination of monthly temperature and precipitation, we construct four CW states - cold and dry, cold and rainy, warm and rainy, warm and dry. Then we demonstrate the possibility of the CW approach to analyze space-time climate similarity and climate change in the Mesopotamian River system. The application of 16 CW states is also discussed. The climate change dynamical assessment (CCDA) showed that the Euphrates (Tigris) tributaries values varied from 13 to 19% (13-25%) with a clear increase in Greater Zab, Lesser Zab, Adhaim, and Dyala basins. The analysis of CW-altered states demonstrated that climate change is occurred due to an increase in temperature, a decrease in precipitation, and mixed changes simultaneously. In each of the basins, there were a different number of such changes. The climate in weather approach developed can be used for processing multidimensional meteorological time series data and outlining the general conception of the regional climate.

Linearna ekonomija kao jednosmjerni model poslovanja kada je u pitanju korištenje resusa karakterisičan je za većinu nacionalnih ekonomija. Pitanja odgovornog upravljanja prirodnim resursima, reciklaža otpada i održivi ekonomski razvoj postaju ključna u svjetskoj ekonomiji 21. vijeka. Cirkularna ekonomija predstavlja proces kruženje materijala (resursa) i njegovu ponovnu upotrebu čime se istovremeno koristi i mnogo manje energije i vode. Evropska komisija je usvojila Akcioni plan za cirkularnu ekonomiju u zemljama EU 2015. godine, ali neke od tih država su skoro 20 godina ranije počele sa primjenom nekih djelova tog plana. Počeci cirkularnog tržišta u Srbiji datiraju od 2017. godine, 2020. godine Vlada usvaja Mapu puta za cirkularnu ekonomiju u Srbiji, a 2022.god. Program razvoja cirkularne ekonomije do 2024.god. Cilj ovog istraživačkog rada je da istakne značaj očuvanja prirodnih resursa za sljedeće generacije uz kvalitetnije životne uslove za širu drušvenu zajednicu putem cirkularne ekonomije i održivog ekonomskog razvoja.
NEJEDNAKOST ZARADA U SRBIJI
Authors: Aleksić Dragan
Published: September 2023

Merenje nejednakosti dohotka na osnovu SILC ankete u Srbiji počelo je početkom prethodne decenije. Od momenta kad su rezultati postali dostupni Srbija spada među zemlje koje karakteriše najviši nivo dohodne nejednakosti u Evropi. Za razliku od nejednakosti dohotka, čiju su rezultati javno dostupni i objavljuju se na godišnjem nivou, o nejednakosti zarada malo se zna. S obzirom na to da zarade predstavljaju glavnu komponentu dohotka, neophodno je detaljnije ispitati oblik njihove distribucije. U ovom radu bavimo se procenom nejednakosti zarada iz različitih izvora podataka i na osnovu različitih indikatora. Rezultati do kojih smo došli ukazuju da je nejednakost zarada znatno niža od nejednakosti dohotka. Štaviše, prema međunarodnim poređenjima Srbija bi se mogla svrstati u zemlje sa umerenom nejednakošću zarada. Navedeni nalazi ukazuju da se bazični uzroci visoke nejednakosti dohotka i nejednakosti u društvu najverovatnije nalaze izvan zarada, pre svega među penzionerima i stanovništvom radnog uzrasta koje se nalazi van tržišta rada.
A Good Tip-Apex Distance Does Not Make Up For a Poor Reduction in Intertrochanteric Hip Fractures Treated with an Cephalomedullary Nail: The Utility of the Neck-Shaft Angle in Preventing Fixation Failure

Published: September 2023

Purpose:

Determine if any fracture characteristics or radiographic parameters were predictive of fixation failure [FF] within 1 year following cephalomedullary nailing for intertrochanteric fractures.

Methods:

A consecutive series of intertrochanteric hip fracture patients (AO/OTA 31A) treated with a cephalomedullary nail were reviewed. Pre-fixation (neck-shaft angle [NSA], distance from ischial tuberosities to greater and lesser trochanters, integrity of lesser trochanter, and fracture angulation) and post-fixation (post-fixation NSA, posteromedial cortex continuity, lag screw position, tip to apex distance [TAD], and post-fixation angulation and translation) radiographic parameters were measured by blinded independent reviewers. The FF and non-FF groups were statistically compared. Logistic regression was performed to determine radiographic parameter correlates of FF.

Results:

Of 1249 patients, 23 (1.8%) developed FF within 1 year. The FF patients were younger than their non-FF counterparts (77.2 years vs 81.0 years, p=0.048), however there were no other demographic differences. The FF cohort did not differ in frequency of TAD over 25 mm (4.3% vs 9.6%, p=0.624) and had decreased mean TAD (13.6mm vs 16.3mm, p=0.021) relative to the non-FF cohort. The FF cohort had a higher rate of a post-fixation coronal plane NSA more than 10° different from the contralateral side (delta NSA>10°, 34.8% vs 13.7%, p=0.011) with the majority fixed in relative varus. For every 1° increase in varus compared to the contralateral side the odds of FF increased 7% (OR=1.065, 95%CI[1.005–1.130], p=0.034) on univariate analysis. On univariate logistic regression, patients with an absolute post-fixation NSA of 10° or more of varus compared to contralateral were significantly more likely to have a FF (OR=3.139, 95%CI[1.067–8.332], p=0.026).

Conclusion:

Despite an acceptable TAD, post-fixation NSA in relative varus as compared to the contralateral side was significantly associated with failure in intertrochanteric hip fractures fixed with a cephalomedullary nail.

Level of evidence:

Prognostic Level III.

The overall purpose of this research was to characterize and comprehend how digitalization influences student behavior at a prestigious institution such as the University of Namibia. The following research questions/and research objectives were developed to achieve this goal. The following were the study’s findings: Around 60 of respondents believed the University of Namibia’s digitalization programme has benefited them. This suggests that pupils were enthusiastic about the digitalization of their learning environment. However, 5 (25%) and 4 (20%) of the respondents, respectively, indicated their dissatisfaction with the results. 4 (20%) of the respondents were undecided because they chose to opt out in the middle of the data collection. Only two respondents (10%) agreed that the University of Namibia’s digital online platforms facilitated a more collaborative lecture room atmosphere. As a result, pupils in the lecture hall were unsatisfied with digital internet platforms, which they described asin adequate and untrustworthy. With this in mind, it is suggested that the University update, restructure, and improve its digitization in order to improve performance and promote learning among stakeholders.

Published: September 2023

The primary goal of this research was to look at the key success elements for effective internal auditing. Internal auditing is the foundation of an organization’s internal control system. Although internal auditing in the public sector has problems, there are success criteria for efficient internal auditing. The investigation focused primarily on the case at the Office of the Auditor General, which audits all of Namibia’s public sector offices. The relevant data for the researcher surveys was obtained from the office’s management team and internal auditors using Google Forms. The study examined empirical literature to establish the important success elements for the Office of Auditor General’s effective internal auditing function. The study’s findings were used to identify and categorize the variables, which were then used to create models. The results of the data analysis were provided in frequency tables and charts. The study’s findings demonstrate that effective internal auditing requires management support and sound management practice, appropriate well-trained and competent internal audit personnel, a functioning board of directors, internal policies, and control. Among the identified criteria, however, managerial support and excellent management practice play a critical role. To improve the efficacy of internal auditing, the research advised that the Office of the Auditor General support internal auditing positions by facilitating internal auditing work and recruiting more trained and qualified internal auditors.

Market risk is connected with the price fluctuations and other market factor movements on four of the world’s most prominent financial markets: Debt securities market, stock market, currency market and commodity market. The high level of unpredictability in the market in which organizations operate is a significant element driving the fast growth of risk measurement and management. Firms are exposed to more market risk in a volatile environment, which offers a motivator for them to develop new and improved risk models. This paper generally analyzes the performance of different models which try to solve, estimate, measure and manage various market risks in order to derive parameters which aid good decision making.
Küresel Değer Zincirlerinde Tedarikçi Firmaların Ekonomik ve Sosyal Yükselmesi: Kurumsal Bir Yaklaşım
Authors: KURT Yusuf
Published: September 2023

Bu makale, küresel değer zinciri (KDZ) katılımı ile ekonomik/sosyal yükselme arasındaki ilişkileri açıklayan kavramsal bir model geliştirmektedir. Ayrıca model, kurumlar kavramının KDZ katılımı ve iyileştirme arasında önerilen ilişkiler üzerindeki düzenleyici etkisini de ortaya koymaktadır. Model, KDZ literatürünü eleştirel bir şekilde irdelemekte ve tedarikçi firmaların KDZ'lere katılarak ekonomik ve sosyal gelişmenin nasıl sağlanabileceğini açıklamaktadır. Her ne kadar literatürdeki çalışmalar yükseltme kavramını anlamayı amaçlamış olsa da bunlar çoğunlukla dar bir yaklaşım uygulamış ve çoğunlukla ekonomik yükselmeye odaklanmıştır. Bununla birlikte, KDZ'deki son olumsuz olaylar (örn. Rana Plaza'nın çöküşü), iyileştirmede bütünsel bir yaklaşım olması gerektiğini ve sosyal iyileştirmenin de katılımcı firmaların iyileştirme hedeflerinin ön saflarında yer alması gerektiğini göstermiştir. Önceki çalışmalar ekonomik gelişmenin nasıl ve hangi koşullarda sağlanabileceğini gösterse de sosyal gelişme ve ayrıca ekonomik ve sosyal gelişme arasındaki etkileşim konusunda sınırlı bir anlayış vardır. Ayrıca, önceki çalışmalar çoğunlukla KDZ'lerin iç dinamiklerine (yani yönetişime) odaklanmış ve yükseltmeyi etkileyen dış faktörlerin önemini gözden kaçırmıştır. Yukarıda bahsedilen araştırma boşluklarından yola çıkan bu çalışma, KDZ'lerde ekonomik ve sosyal gelişmenin nasıl ve hangi bağlamlarda sağlanabileceğini açıklayan kavramsal bir model geliştirerek literatüre anlamlı bir katkı sağlamaktadır. KDZ katılımı, ekonomik ve sosyal gelişme ve kurumlar arasındaki etkileşimler altı önermeyle eleştirel bir şekilde açıklanmış ve kavramsallaştırılmıştır. Küresel değer zincirleri, küresel ticaretin önemli bir bileşeni haline gelirken, bu çalışma, ekonomik ve sosyal gelişmenin nasıl ve hangi koşullar altında sağlanabileceğini anlamayı amaçlayan gelecekteki çalışmalar için fırsatlar yaratmaktadır.
EXERCÍCIO DA JURISDIÇÃO CONSTITUCIONAL PELO SUPREMO TRIBUNAL FEDERAL NA DEFESA DA DEMOCRACIA DURANTE A PANDEMIA DA COVID-19
Authors: Dias Rafael Vitor Macedo , De Mendonça Gustavo Olympio Scavuzzi
Published: September 2023

O presente artigo tem como objetivo analisar a crise das democracias contemporâneas a partir da perspectiva de Steven Levitsky e Daniel Ziblatt, de modo a investigar como governantes eleitos promovem a erosão de regimes democráticos. Inicialmente, buscou analisar o conceito de democracia e a partir desta premissa, investigar a crise ocorrida no Brasil durante o governo Bolsonaro, especificamente quando da pandemia do COVID-19, e como o Supremo Tribunal Federal, no exercício da jurisdição constitucional atuou para conter o avanço autocrático realizado pelo chefe do Poder Executivo Federal. A pesquisa utilizou o método dedutivo, com a utilização de revisão bibliográfica e de decisões judiciais preferidas pelo STF.  Concluiu-se, ao final, que a Suprema Corte atuou dentro dos limites que asseguram a sua legitimidade para limitar o avanço antidemocrático sustentado pelo então Presidente Bolsonaro, contudo o exercício enérgico da jurisdição constitucional deve ser constantemente monitorada para não promover um desequilíbrio entre os poderes.

Authors: Luna Nathalia Martins
Published: September 2023

O presente artigo tem por objetivo analisar a formação cultural, social e religiosa a partir dos diálogos e demais enfrentamentos sofridos pelos grupos de judeus, muçulmanos e cristãos dentro da Espanha que estava sob a administração dos Reis Católicos, Isabel de Castela e Fernando de Aragão, no século XV. A discussão apresentada apresenta como problemática central como esses três segmentos religiosos se estruturaram, compartilharam suas definições de moralidade e simbolismos religiosos e demais trocas culturais em um ambiente hostilizado, marcado pela regência e implementação do projeto de unificação dos Reis Católicos dentro do território hispânico. Será explorado, assim, as diversas ações de resistência de judeus e muçulmanos, as políticas de controle institucional e de segregação espacial aplicadas a um nível sociocultural, proporcionada pela coroa, juntamente com a compreensão da Guerra de Granada (1492) como ponto basilar para a mudança de leis e a expulsão daqueles que professavam a fé islâmica dentro do território castelhano. Desta forma, é de suma importância a investigação desta conexão cultural através de um olhar crítico humanizado para compreender os diversos simbolismos gerados por um hibridismo cultural e religioso dentro deste ambiente único, evidenciando as particularidades destas interligações e redes de conexão entre estes grupos.

Published: September 2023

O objetivo deste trabalho é analisar a diferença de rendimentos entre diferentes níveis de renda segundo o sexo no estado do Paraná, nos anos 2012 e 2019. Para tal, utiliza-se do arcabouço da Decomposição Quantílica proposta por Firpo et al. (2018) com os microdados da Pesquisa Nacional por Amostra de Domicílios Contínua (PNADC). Apesar do aumento da participação das trabalhadoras no mercado de trabalho paranaense no período analisado, os resultados denotam que as mulheres recebiam, em média, um salário inferior ao salário dos homens, tanto em 2012 quanto em 2019, com uma redução do diferencial no período analisado. Analisando com relação às características observáveis, percebeu-se uma tendência de reversão dessa divergência, com as trabalhadoras auferindo maiores remunerações médias, independente do quantil de análise. Dessa forma, é possível apontar que a maior parte desse diferencial é ocasionado pela contribuição de características não observadas, um indicativo de discriminação no mercado de trabalho paranaense.

Työväenluokan puoluevalinnat sekä niitä selittävät arvot ja asenteet 2010-luvulla
Authors: Tiihonen Aino
Published: September 2023

Aino Tiihonen analysoi artikkelissaan työväenluokan äänestyskäyttäytymistä 2010-luvun Suomessa. Tarkastelukohteena ovat erityisesti puoluevalintoihin vaikuttavat arvot ja asenteet. Artikkelissa nousee esiin, että luokkasamaistuminen ja ammattiasema eivät enää kulje yhtä voimakkaasti käsi kädessä kuin ennen. Myös työväenluokkaisuus on muuttanut muotoaan, ja sitä on syytä tarkastella monimuotoisemmin kuin pelkkänä ammattiasemana. Tiihosen vaalitutkimusaineistoihin perustuvassa analyysissä korostuu suomalaisen poliittisen kentän murros. Perussuomalaiset on noussut suosituksi niin perinteisenammattiin sidotun työväenluokan kuin myös uudenlaisiin työväenluokkapositioihin sidottujen äänestäjien keskuudessa. Jo 1960-luvun lopulta asti niin sanotun populistit ovat aika ajoin saaneet merkittävää suosiota länsimaisen ”vauraan” työväestön keskuudessa. Nyt tämä trendi on rantautunut myös Suomeen.

Published: September 2023

Background: Cardiovascular diseases are among the leading cause of morbidity and mortality worldwide. The association between HIV and CVD has been established in many studies. However, information is still lacking on subclinical disease as well as its associated risk factors in this population. This study aimed at establishing the prevalence of subclinical CVD among clinically healthy HIV people attending their regular out- patient visits. It also looked at risk factors (traditional and non traditional) as well as the association of CVD to the CD4 count.

Methods: we enrolled a total of 243 asymptomatic HIVinfected patients from the HIV outpatient clinic at the University Teaching Hospital. Data collected included demographic characteristics, duration of HIV infection, drug history including HAART regimen and cardiovascular risk factors (hypertension, diabetes and smoking). Clinical data included blood pressure, weight and height. Laboratory data included CD4 counts, serum creatinine, total cholesterol and triglycerides. We  tested for subclinical CVD using 3 tools: Ankle Brachial Index (ABI) to measure for the presence of peripheral artery disease, 12 lead Electrocardiogram (ECG) for  electrical abnormalities and transthoracic Echocardiography (ECHO), to measure abnormalities in cardiac structure and function. At analysis, patients where  dichotomised into those with CD4≤350 and those with CD4>350.

Results: participants characteristics were as follows: the mean age, 42 years (SD±10); 143 (58.5%) females; CD4≤350cells/ml was found in 140 (57.6%); 112(86.2%) were receiving HAART with 86.2% being on 1st line regimen. Systolic hypertension was present in 84(34.6%), diastolic hypertension in 89(36.6%) and 39.5% had creatinine clearance<90. Diabetes and current smoking were not very common (3.3% and 2.9% respectively). High total cholesterol was found in  19(7.82%) of the participants while 37(15.23%) had high triglycerides. On ECG, ECHO and ABI, abnormalities were found in 53.9%, 44.4% and 20.2%   respectively). The commonest cardiac lesion on both ECG and ECHO was left ventricular hypertrophy (27.4% and 23.3%  respectively). Participants with CD4≤350 had higher prevalence of abnormalities on ECG (P=0.022) and ABI (P=0.043). Clinical factors associated with increased risk of subclinical CVD on multivariate logistical regression included CD4≤350, systolic BP>140mmHg and diastolic BP >90mmHg.

Conclusions: Prevalence of subclinical CVD in healthy HIV infected patients is high and those with CD4≤350 have a higher risk. Hypertension is the most important traditional CVD risk factor in this population. There is need to screen HIV patients attending their routine clinic visits for hypertension and subclinical CVD. ABI and ECG are readily available in most institutions and can be used with minimal  expertise.

Authors: Sezgin Mehtap
Published: September 2023

This research aims to examine research on Social and Emotional Learning (SEL) in Turkey in the 21st century. A qualitative approach was used in the sample of 43 studies conducted in Turkey between January/2001-January/2023, including research articles and theses in SEL. The data was collected through document analysis from the databases of the Turkey National Thesis Center of the Council of Higher Education and Ankara Social Sciences University Library, and the Documentation Department. The data was analyzed by descriptive analysis. Findings proved that SEL measurement tools were developed and adapted as self-reports from primary school to higher education. SEL is correlated with desirable/positive and undesirable/negative traits in children and youth. There are short-term interventions developed and adapted. These programs are effective in improving SEL. As a result, it can be declared that the importance of SEL in raising healthy, successful, and happy generations is accepted in Turkey. However, there is a need for more systematic studies on SEL, both in theory and in practice. First of all, SEL standards should be determined at the national level, considering the cultural sensitivity of the SEL.

Published: September 2023

This paper seeks to provide an overview of publications in Saudi Arabia in the field of computer curriculum in K-12. We applied a systematic review methodology to analyze publications through 2021. Out of 225 publications initially identified, 110 were included based on the inclusion and exclusion criteria. The findings show that the number of publications in the field of computer curriculum in K-12 increased until 2018 but started to decrease in 2019. In addition, computer curriculum research trends focused on the high school stage, followed by the intermediate stage, and most participants were teachers and students. Moreover, the qualitative approach was frequently used in empirical studies, while most methodologies were surveys and semi-experimental. The results show that most of the papers’ suggestions involved training teachers and developing the curriculum. Finally, the study presents some recommendations for computer curriculum research. It suggests developing a research center in the education ministry to encourage researching the curriculum and presents other suggestions in detail.

Human Capital for Innovation Capacity in Middle-Income Economies
Authors: Ngo Huong Thu
Published: September 2023

This paper examines the impact of the human capital composition of unskilled, skilled, and high-skilled levels on the innovation capacity of middle-income economies. Data from 65 countries in lower middle-income, upper middle income, and high-income categories over the period of 1985-2019 is used. Panel data regressions are employed. Results suggest the innovation capacity enhancing effects of high-skilled human capital in upper-middle income countries (UMICs) and high-income countries. For lower middle-income countries (LMICs), the skilled human capital is the important workforce fostering their innovation capacity, while the R&D personnel of high-skilled human capital is yet to be important. Unskilled human capital is confirmed to not play any role in innovation development in MIEs and above. For UMICs, high-skilled human capital is supported by the foreign innovation diffusion through imports, and R&D capital stocks; while for LMICs, FDI-embodied foreign innovation supplements the skilled human capital to build up innovation capacity.

Published: September 2023

The underground economy (UE) briefly comprises services, activities, and transactions, which could be legal or illegal. In this paper the size of UE is estimated through mathematical fuzzy model based on fuzzy set, fuzzy logic and constructed a yearly time-series for UE over the period 2001 to 2020 in Afghanistan. Two input variables are used; unemployment rate (UR) and the government regulations (REG). Fuzzification, fuzzy inference and defuzzification; the three steps that are considered for estimating UE in the country, based on mean and standard deviation (SD) for each variable individually. The result indicates four cycles for time series and shows that people were more involved in UE activities over the first and third cycles and less involved over the second and fourth cycles.

Published: September 2023

A orientação motivacional durante o exercício da profissão docente desempenha um papel fundamental não só para a qualidade da atividade de ensino do professor, mas também como uma variável influenciadora na motivação e no engajamento dos estudantes. Diante desta premissa, o objetivo do presente estudo foi identificar de que maneira a motivação para a docência no Ensino Superior vem sendo debatida nas pesquisas desenvolvidas sobre a temática nos últimos oito anos (2015 - 2023/até o momento). Para alcançar o objetivo proposto, foi desenvolvida uma pesquisa bibliográfica e os dados foram analisados mediante à abordagem de análise de conteúdo, a qual permitiu categorizá-los. Foram obtidas três categorias: a) motivação docente relacionada ao estudante; b) motivação docente e a realização profissional; c) motivação docente, status e sentimento de pertencimento. A partir da análise das categorias, verificou-se novas possibilidades de estudos que abordem a motivação no contexto universitário. Também foi considerada a necessidade de investigações sobre a organização de formações continuadas direcionadas à docentes a fim de que haja apropriação sobre a importância da sua orientação motivacional e que caminhos sejam viabilizados para formas efetivas de engajamento nos estudos dos universitários a partir deste constructo.

Published: September 2023

O Brasil é amplamente dependente de suas rodovias, as quais são a principal forma de transporte de cargas e passageiros no país, em função disso, anualmente são investidas vultosas quantias para ampliar e manter a rede viária. Uma técnica comum para restauração dos pavimentos é a fresagem, a qual envolve o corte e remoção da camada deteriorada. Muitos países reutilizam o material fresado na construção de novas vias, essa prática, no entanto, não possui adesão significativa no Brasil. Assim, a necessidade de manutenção dos pavimentos se alia à expressiva quantidade de material fresado gerada, levando a um aumento no volume de novos agregados a serem extraídos das jazidas, o que torna a pressão sobre os recursos naturais insustentável. O propósito deste estudo é analisar a viabilidade da substituição de parte do agregado convencional por material fresado, a partir da criação de um traço contendo Cimento Portland como estabilizante químico, propondo, desse modo, uma alternativa que atenda à demanda por reabilitação das vias nacionais e vise qualidade, economia, e respeito ao meio ambiente. Para atingir esses objetivos, desenvolveu-se uma mistura constituída 75% por material fresado e 25% por solo, à qual incorporou-se cimento CP V-ARI nos teores de 8 e 10%. Foram realizados todos os ensaios previstos em normas para análise das propriedades da mistura, os quais atestaram sua aptidão para uso como camada de base de solo-cimento. O ensaio de Resistência à Compressão Simples expôs resultados acima do mínimo normativo, sendo 2,76MPa para 8% de estabilizante e 3,42MPa para 10%, valores que denotam a rigidez e o potencial de aplicação do composto, incentivando futuras pesquisas acerca desta temática.

Published: September 2023

The glyphosate herbicide when applied in post-emergence in transgenic soybean can influence manganese (Mn) nutrition, with differentiated response when parceled out. The objective of this study was to evaluate the soybean response to Mn sources applied via leaf, in different phenological stages. Two experiments were carried out in areas with different Mn contents in the soil, using four Mn sources, sulphate and nitrate (experiment A), phosphite and Mn-EDTA (experiment B). Leaf application of Mn was done at V8 and V12 (150+150 g ha-1), V8 (single application at 300 g ha-1) and V12 (single application at 300 g ha-1). In experiment A, the plants treated with nitrate, in split application, had greater leaf area and height of insertion of the first pod. The nitric source resulted in higher soybean yield when applied at V12. On the other hand, sulphate provided plants with higher height at harvest and higher yield with split application. In experiment B, it was found a larger leaf area with application of Mn-EDTA in V12. The application of phosphite provided higher at harvest height when applied in V8 and higher leaf Mn content when applied in V12. The insertion of the first pod was lower in plants treated in V12 with phosphite or with Mn-EDTA and V8. The Mn-EDTA source resulted in higher yield of transgenic soybeans at a dose of 300 g ha-1, applied at V8 or V12, in no-till area with low Mn content in the soil.

Authors: Guitarrara Leandro Bozzola , Dos Santos Sibele Gabriela
Published: September 2023

A obrigatoriedade do estudo da história e cultura afro-brasileira no ensino fundamental e médio público e privado são essenciais para uma educação verdadeiramente antirracista. O objetivo geral dessa pesquisa é realizar reflexões sobre a inefetividade prática da regra impositiva dessa obrigatoriedade e os impactos negativos causados, dentre os quais a perpetuação de racismo estrutural, institucional e do epistemicídio negro. Utilizar-se-á de metodologia dedutiva e método crítico dialético, mediante pesquisa bibliográfica e análise documental. Até o momento a pesquisa demonstra a existência de obstáculos à implementação de uma educação antirracista efetiva, como a falta de capacitação continuada dos profssionais que atuam no sistema de educação tanto nas redes públicas, quanto nas privadas. Espera-se, ao final dessa pesquisa, contribuir para os debates a respeito da inefetividade da atual política pública de educação antirracista.

O trabalho teve como objetivo avaliar o efeito de doses de pó rocha de basalto associadas a cama de frango e esterco bovino sobre os teores de nutriente na folha da soja, tendo como referência a adubação a adubação química solúvel (NPK). O experimento foi conduzido em blocos ao acaso (DBC), em arranjo fatorial (5x2) + 1, com quatro repetições. Foi utilizado cinco doses de pó de rocha de basalto (0, 4, 8, 12 e 16 t ha-1) associadas a duas fontes de resíduos de origem animal: esterco bovino e cama de frango (5 t ha-1). No tratamento adicional, foi usado adubação química solúvel com 300 kg ha-1 do formulado comercial 02-20-18 (NPK) no cultivo da soja. Avaliou-se os teores de nutrientes foliares: N, P, K, Ca e Mg. As doses de basalto em associação a cama de frango e esterco bovino proporcionaram resultados positivos nos teores de nutrientes foliares da soja, apresentado teores dentro da faixa recomendada para um bom crescimento e desenvolvimento das culturas. Os resultados das características avaliadas sob o efeito das doses de basalto, cama de frango e esterco bovino foram iguais as constatadas quando se utilizou a adubação química solúvel (NPK). Assim, os teores foliares de P e K da soja apresentaram incrementos com o uso do pó de rocha de basalto até as doses de pó de rocha de basalto de 11,3 t ha-1 e 16,0 t ha-1 associado a cama de frango e até as doses de basalto de 6,7 t ha-1 e 8,5 t ha-1 com o esterco bovino, respectivamente; e Ca e Mg aumentaram expressivamente sua disponibilidade com a elevação das doses de pó de rocha de basalto.
