Published: April 2022

Measured evapotranspiration (LE) of screenhouse banana plantations was utilized to derive and compare two types of machine-learning models: artificial neural network (ANN) and multiple linear regression (MLR). The measurements were conducted by eddy-covariance systems and meteorological sensors in two similar screenhouse banana plantations during two consecutive seasons, 2016 and 2017. Most of the study focused on the season of 2017, which includes a more extended data set (141 days) than 2016 (52 days). The results show that in most cases, the ANN model was superior to MLR. When trained and validated over the whole data set of 2017, the ANN and MLR models provided R2 of 0.92 and 0.89, RMSE of 37.5 and 45.1 W m−2 and MAE of 21 and 27.2 W m−2, respectively. Models could be derived using a training dataset as short as one month and still provide reliable estimations. Depending on the chosen calendar month for training, R2 of the ANN model varied in the range 0.81–0.89, while for the MLR model, it ranged 0.73–0.88. When trained using a data set as short as one week, there was some deterioration in model performance; the corresponding ranges of R2 for the ANN and MLR models were 0.37–0.89 and 0.37–0.71, respectively. As expected for a screenhouse decoupled environment, solar radiation (Rg) was the variable that most influenced LE; using Rg as the sole input variable, the ANN model resulted in R2, RMSE and MAE of 0.88 and 47 W m−2 and 25.6 W m−2, respectively, values that are not much worse than using all input variables (solar radiation, air temperature, air relative humidity and wind speed). Using Rg alone as the input to the MLR model only slightly deteriorated R2 (=0.88); however, RMSE (=124 W m−2) and MAE (=75.7 W m−2) were significantly larger compared to a model based on all input variables. To examine model performance in different seasons, models were trained using the data set of 2017 and validated in 2016, and vice versa. Results showed that training on the data of 2017 and validation in 2016 provided superior results than the opposite, presumably since the 2017 measurement season was longer and weather conditions were more diverse than in the 2016 data set. It is concluded that the ANN and MLR models are reasonable options for estimating evapotranspiration in a banana screenhouse.

Published: April 2022

Surface water quality management is an important facet of the effort to meet increasing demand for water. For that purpose, water quality must be monitored and assessed via the use of innovative techniques, such as water quality indices (WQIs), spectral reflectance indices (SRIs), and multivariate modeling. Throughout the Rosetta and Damietta branches of the Nile River, water samples were collected, and WQIs were assessed at 51 different distinct locations. The drinking water quality index (DWQI), metal index (MI), pollution index (PI), turbidity (Turb.) and total suspended solids (TSS) were assessed to estimate water quality status. Twenty-three physicochemical parameters were examined using standard analytical procedures. The average values of ions and metals exhibited the following sequences: Ca2+ > Na2+ > Mg2+ > K+, HCO32− > Cl− > SO42− > NO3− > CO3− and Al > Fe > Mn > Ba > Ni > Zn > Mo > Cr > Cr, respectively. Furthermore, under the stress of evaporation and the reverse ion exchange process, the main hydrochemical facies were Ca-HCO3 and mixed Ca-Mg-Cl-SO4. The DWQI values of the two Nile branches revealed that 53% of samples varied from excellent to good water, 43% of samples varied from poor to very poor water, and 4% of samples were unsuitable for drinking. In addition, the results showed that the new SRIs extracted from VIS and NIR region exhibited strong relationships with DWQI and MI and moderate to strong relationships with Turb. and TSS for each branch of the Nile River and their combination. The values of the R2 relationships between the new SRIs and WQIs varied from 0.65 to 0.82, 0.64 to 0.83, 0.41 to 0.60 and 0.35 to 0.79 for DWQI, MI, Turb. and TSS, respectively. The PLSR model produced a more accurate assessment of DWQI and MI based on values of R2 and slope than other indices. Furthermore, the partial least squares regression model (PLSR) generated accurate predictions for DWQI and MI of the Rosetta branch in the Val. datasets with an R2 of 0.82 and 0.79, respectively, and for DWQI and MI of the Damietta branch with an R2 of 0.93 and 0.78, respectively. Therefore, the combination of WQIs, SRIs, PLSR and GIS approaches are effective and give us a clear picture for assessing the suitability of surface water for drinking and its controlling factors.

Published: April 2022

This study focused on the trends of rainfall variability and drought monitoring in the northern region of Pakistan (Gilgit-Baltistan). Climate Hazards Group Infrared Precipitation with Stations (CHIRPS) model data were used for the period of 1981 to 2020. The Standardized Precipitation Index (SPI) was applied to assess the dry and wet conditions during the study period. The Mann–Kendall (MK) and Spearman’s rho (SR) trend tests were applied to calculate the trend of drought. A coupled model intercomparison project–global circulation model (CMIP5–GCMs) was used to project the future precipitation in Gilgit-Baltistan (GB) for the 21st century using a multimodel ensemble (MME) technique for representative concentration pathway (RCP) 4.5 and RCP 8.5. From the results, the extreme drought situations were observed in the 12-month SPI series in 1982 in the Diamir, Ghizer, and Gilgit districts, while severe drought in 1982–1983 was observed in Astore, Ghizer, Gilgit, Hunza-Nagar, and Skardu. Similarly, in 2000–2001 severe drought prevailed in Diamir, Ghanche, and Skardu. The results of MK and SR indicate a significant increasing trend of rainfall in the study area, which is showing the conversion of snowfall to rainfall due to climate warming. The future precipitation projections depicted an increase of 4% for the 21st century as compared with the baseline period in the GB region. The results of the midcentury projections depicted an increase in precipitation of about 13%, while future projections for the latter half of the century recorded a decrease in precipitation (about 9%) for both RCPs, which can cause flooding in midcentury and drought in the latter half of the century. The study area is the host of the major glaciers in Pakistan from where the Indus River receives its major tributaries. The area and volume of these glaciers are decreasing due to warming impacts of climate change. Therefore, this study is useful for proper water resource management to cope up with water scarcity in the future.

Published: April 2022

Dam safety monitoring is of vital importance, due to the high number of fatalities and large economic damage that a failure might imply. This, along with the evolution of artificial intelligence, has led to machine learning techniques being increasingly applied in this field. Many researchers have successfully trained models to predict dam behavior, but errors vary depending on the method used, meaning that the optimal model is not always the same over time. The main goal of this paper is to improve model precision by combining different models. Our research focuses on the comparison of two successful integration strategies in other areas: Stacking and Blending. The methodology was applied to the prediction of radial movements of an arch-gravity dam and was divided into two parts. First, we compared the usual method of estimating model errors and their hyperparameters, i.e., Random Cross Validation and Blocked Cross Validation. This aspect is relevant not only for the importance of robust estimates, but also because it is the source of the data sets used to train meta-learners. The second and main research topic of this paper was the comparison of combination strategies, for which two different types of tests were performed. The results obtained suggest that Blocked CV outperforms the random approach in robustness and that Stacking provides better predictions than Blending. The generalized linear meta-learners trained by the Stacking strategy achieved higher accuracy than the individual models in most cases.
Study on the Relationship between River Water and Groundwater under Different Aquifer Mediums

Published: April 2022

There is a strong river water–groundwater hydraulic connection, particularly in arid and semi-arid regions in which rivers are the main source of groundwater recharge. Therefore, a study of this relationship is of great practical significance. This study investigated this relationship for three kinds of homogeneous sand with different particle sizes using sandbox experiments. Consistent with previous studies, as the moisture of the sand decreased, the discharged water level continued to decline and the hydraulic connection between river water and groundwater was gradually lost. Discharged flow increased as the discharge level decreased and stabilized after reaching a maximum threshold. However, inconsistent with the results of previous studies, the thickness of the inverted saturation zone was not always equal to the river water depth. In addition, the maximum discharge flow resulting from cutting off the river and groundwater was different from that noted in previous studies. A coarse sand water-bearing medium resulted in a thickness of a suspended saturated zone of 15–20 cm, for 18.5 cm river water depth and 5–10 cm for 10 cm river water depth. The results for medium sand with a thickness of 5–10 cm (18.5 cm river water depth) was the disappearance of the suspended saturated water zone (10 cm river water depth), as it was for a fine sand thickness of 15–20 cm (18.5 cm river water depth), and a thickness of 10–15 cm (10 cm river water depth). The results indicated that the thickness of the inverted saturation zone formed by the separation of the connection between the river and the groundwater is not only related to the depth of the river, but also affected by various physical parameters of the aquifer. An empirical formula for calculating the thickness of the inverted saturation band is given based on the experimental results.
Numerical Investigation on Solitary Wave Interaction with a Vertical Cylinder over a Viscous Mud Bed
Authors: Guo Ronglian , Lo Peter H.-Y.
Published: April 2022

This study investigated the hydrodynamics of a solitary wave passing a vertical cylinder over a viscous mud bed for the first time. A highly viscous Newtonian fluid was assumed as a simplified model for fluid mud. A three-dimensional numerical wave flume consisting of a fixed cylindrical structure and three viscous fluids—air, water, and mud—was constructed and validated. Numerical experiments were performed to investigate solitary wave interaction with a vertical cylinder over a viscous mud bed. Numerical results showed the mud surface deformation to be one order of magnitude smaller than the water surface deformation and their behaviors to be different: mud surface depressions occurred on the upstream and downstream sides of the cylinder, whereas mud surface elevations occurred on the lateral sides of the cylinder. This solitary wave induced scour pattern on a muddy seabed is different from that commonly observed on a sandy seabed. Water flow reversal near the water–mud interface was made more evident by the mud bed. Although the mud bed attenuated water waves, it nevertheless increased the total horizontal force and toppling moment exerted on the cylinder due to the wave-induced mud flow. These findings may be valuable to the design of marine structures on a muddy seabed and worthy of further investigation.

Published: April 2022

Exogenous drivers may cause a gradual and reversible change in a lake equilibrium, or they may force it over a threshold to a persistent alternative stable state, described as a regime shift in the ecosystem. In the mid-and-lower Yangtze River Basin (MLYB), major environmental problems in shallow lakes have been eutrophication and abrupt algal blooms under anthropogenic disturbances for the recent century. Much value is therefore placed on understanding the changes in shallow-lake ecosystems that characteristically precede changes in the state of the lake. Here, we describe a case study of the paleolimnological signature in diatom assemblages of various types of regime shifts caused by historically documented anthropogenic drivers in a temperate shallow lake: Taibai Lake. We evaluate the effectiveness of paleolimnological data as a surrogate for long-term monitoring. Algorithms using sequential t and F statistics detected breakpoints in the time series of diatom assemblages, in 1994–1996, 1974–1977, 1952–1956, and 1931–1934, respectively. The regression statistics suggest that the hydrodynamic–ecosystem and aquacultural–ecosystem relationships fit better in the breakpoint regression model, and the relationship between nutrient loading and ecosystem state suits the linear model. Feedback loops help reconstruct dynamic changes in Taibai influenced by major stressors. Our study exemplifies the value of system approaches to identifying regime shifts and their possible causes in shallow lakes from paleolimnological records. The case study of Taibai set an example of reconstructing the ecological regime shifts in shallow lakes in the MLYB and understanding the state changes in lake ecosystems, which will benefit effective lake management.

Freshwater macroalgae produces a wide range of bioactive compounds, and interest in utilizing its biomass is growing rapidly. Meanwhile, exploiting renewable sources for biomass collection could lead to more sustainable biotechnological chains. The aim of this study was to investigate Cladophora glomerata biomass from Lithuanian rivers as a potential raw material for biotechnology. For this reason, phenolic compound profiles, antioxidant activity and pigment concentrations were determined in macroalgal biomass samples collected from the following four Lithuanian rivers: Dubysa (B1), Šventoji (B2), Nevėžis (B3) and Jūra (B4). The highest total phenolic compound content was determined in B3 (1.32 mg GAE/g). Three phenolic acids were identified, namely gallic (12.94–35.13 µg/g), p-hydroxybenzoic (23.97–29.05 µg/g) and p-coumaric (1.79–6.46 µg/g). The results indicate significant C. glomerata antioxidant activity; the highest reducing power reached 0.737 AU (B3), the total antioxidant content was 1.47 mg Trolox/g (B3), DPPH and ABTS radical scavenging was 11.09% (B3) and 97.86% (B1) and FRAP activity 20.86 µmol/L (B3). The content of pigments ranged from 0.56-0.74, 0.39–0.57, 0.17–0.23 to 0.11–0.17 mg/g in chlorophyll a, b, carotenoids, and lutein, respectively. To conclude, C. glomerata macroalgal biomass may have the potential to act as a functional raw material, as several groups of bioactive compounds and antioxidant activities were observed.
The Water Footprint of Biodiesel Produced from Sunflower in South Africa
Authors: Netshifhefhe Khwathiso , Jordaan Henry
Published: April 2022

The use of feedstock crops for the production of biodiesel suggests that biodiesel production may have a major impact on the scarce freshwater resource in South Africa. This paper aimed to assess the green plus blue water footprints (WFgreen+blue) of biodiesel produced from sunflower in South Africa using the Global Water Footprint Standard approach. The green (WFgreen) and blue water footprint (WFblue) at the farm level were assessed for sunflower grown under the rain-fed and irrigation production system respectively. The results show that 2617 m3 and 2477 m3 are required to produce 1 ton of rain-fed and irrigated sunflower respectively. At the processing level, about 7.12 L of blue water is required to produce 1 L of biodiesel from sunflower. The WFblue at the processing stage of biodiesel produced from irrigated sunflower was 1.01 m3/GJ, compared to 1.15 m3 m3/GJ from rain-fed sunflower. The WFgreen+blue of biodiesel produced from irrigated and rainfed sunflower was 2477 and 2617 m3/ton, respectively. WFgreen was the largest, accounting for about 59% and 99% for biodiesel produced from irrigated and rain-fed sunflower, respectively. It was further found that water consumption at the farm level accounted for about 99% of the WFgreen+blue of biodiesel in both production systems. Management practices that improve water use efficiency at the farm level may help to lower the WFgreen+blue of biodiesel. Interestingly, the WFgreen+blue is lower for biodiesel produced from irrigated sunflower than for rainfed sunflower. The blue water scarcity assessment showed that blue water scarcity is low during the period when sunflower requires water. As such, purely from a water use perspective, irrigated sunflower production in the Orange Riet Irrigation Scheme may be considered sustainable.

Published: April 2022

This study presents an integrated analysis of cohesive bank-collapsed material transportation in a high-curvature channel with a non-cohesive riverbed. A numerical model was established to simulate the erosion and transportation of collapsed materials in a 180° U-bend channel after verification. The novel aspect of this study is that the quantities of the collapsed materials that transformed into suspended and bed loads were comprehensively analyzed. The results show that finer collapsed sediments were only transformed into suspended loads after being eroded, while the coarser particles transformed into both suspended loads and bed loads. When the flow charge was 30 L/s, the quantity of collapsed materials (S1 and S2) that transported downstream was smaller, and coarser materials transformed into suspended loads with a ratio of 88.12–99.86% and bed loads with a ratio of 11.18–0.14%. When the flow charge was 55 L/s, due to the greater shear stress, the quantity of collapsed materials (S1 and S2) that transported downstream was greater, and the ratio ranged from 46.65% to 49.88% and from 50.12% to 53.35%, respectively. This research provides theoretical and practical benefits that reveal the mechanisms of channel bend evolution.

Published: April 2022

In an Islamic perspective, theoretical character education has actually existed since Islam was revealed in the world along with the sending of the prophet Muhammad SAW. to improve or perfect human character. Islamic character is the nature, character, morality, ethics, or behavior that is Islamic. Islamic character can be understood as an effort to instill intelligence in students in thinking, behaving, and behaving in accordance with the noble values that become their identity, manifested in interactions with God, themselves, among others and their environment. With this irritating phenomenon because at this time moral degradation is increasing infecting the younger generation, of course this is a special concern for education actors so that there are efforts to improve moral issues and good personality character. Education must of course teach Islamic characters that encourage children to have an Islamic spirit to become human beings who believe and fear Allah SWT.

Çalışmanın amacı, gebelerin Covid-19 durumlarına göre anksiyete ve depresyon düzeylerinin karşılaştırılmasıdır. Tanımlayıcı tipte yer alan bu çalışma İstanbul’da özel bir hastanede yürütülmüştür. Veri toplama aracı olarak kullanılan anket; genel bilgiler (yaş, eğitim durumu, çalışma durumu, gebelik sayısı, doğum sayısı), Beck Ansiyete Ölçeği ve Beck Depresyon Ölçeğinden oluşmaktadır. Çalışmada ele alınan konuya bağlı olarak I. Tip hata (α ) genellikle 0.005, 0.01, 0.05 ve 0.10 olarak alınmaktadır. Çalışmanın ilgili olduğu konu fizik ve sağlık bilimleri gibi gelişmiş ve hassasiyetin önemli olduğu bilim dalları ise I. Tip hata 0.005 veya 0.01 olarak alınmakta; sosyal bilimler gibi alanlarda ise 0.05 veya 0.10 olarak alınabilmektedir (Ünver ve ark., 2013) . Bu çalışmada I. Tip hata 0.10 alınarak analizler ve yorumlamalar yapılmıştır. Uygulanan ölçeklerin geçerlik ve güvenilirliği Cronbach Alpha ile test edilerek Covid-19 geçirme durumunun yaş, gebelik sayısı, doğum sayısı, Beck Anksiyete ve Beck Depresyon ölçeklerine göre farklılığın karşılaştırılmasında Mann Whitney U testi kullanılmıştır Covid-19 geçirme durumunun, eğitim ve çalışma durumları ile ilişkisi için ise Pearson Ki-kare testi kullanılmıştır. Çalışma kapsamına toplam 137 kadın dâhil edilmiştir. Çalışma kapsamına alınan kadınların 61 ‘ine Covid-19 tanısı konulmuştur. 76 kadına ise Covid-19 tanısı konulmamıştır. Tüm maddeler için elde edilen α değeri o anketin toplam güvenilirliğini gösterir ve genel kabul bu değerin 0.7 ve daha büyük olmasıdır (Çakmur,2012) . Bu doğrultuda ölçeklerin Cronbach Alfa değerleri 0.7’den yüksek olması beklenir. Bu bilgi ışığında 21 soruluk 3 başlık altında incelenen Beck Anksiyete Ölçeğinin Cronbach Alfa değeri 0.897 olarak ölçülmüştür. Beck Depresyon Ölçeğinin Cronbach Alfa değeri ise 0.853 olarak ölçülmüştür.Eğitim durumu ile Covid-19 tanısı alma arasında bir ilişki bulunmaktadır (p = 0.021 <0.10).Covid-19 tanısı alanların içerisinde de doğum sayısı(p = 0.004 <0.10), duygusal belirtiler alt boyutu (p = 0.057 <0.10) ve Beck Anksiyete ölçeği ( p = 0.058 < 0.10) açısından istatistiksel olarak anlamlı bir sonuca ulaşılmıştır.

Published: April 2022

Tedavi olmak ve sağlık hizmeti alma amacıyla ülke sınırlarının dışına seyahat etme anlamına gelen sağlık turizmi, son yıllarda ülkelerin kalkınmasına katkı sağlayan alternatif bir turizm türü olarak ortaya çıkmıştır. Dijitalleşen dünyada insanların birbiriyle olan iletişiminde önemli bir yer tutan dijital platformlarda yapılan ürün ve hizmetlere yönelik yorumlar, tüketici davranışlarını ve kararlarını etkileyen elektronik ağızdan ağıza pazarlama olarak adlandırılmıştır. Sağlık turizminde elektronik ağızdan ağıza pazarlamanın, tedavi olmak üzere gidilen ülkeye duyulan güven ve seyahat niyeti üzerinde etkili olduğu düşünülmektedir.
Bu çalışmanın amacı, sağlık turizminde elektronik ağızdan ağıza pazarlamanın bölgesel güven ve seyahat niyeti üzerine etkisini ölçmektir. Bu kapsamda Ankara’da faaliyet gösteren bir özel hastanenin ülkemize sağlık hizmeti almak için gelen yabancı uyruklu hastalarına anket uygulaması gerçekleştirilmiştir. Bu kapsamda Ocak 2020-Mayıs 2020 tarihleri arasında hastanede tedavi hizmeti alan ve çalışmaya katılmaya gönüllü olan toplam 286 hasta örneklem olarak alınmıştır. Anket formu, kişisel bilgi formu, elektronik ağızdan ağıza pazarlama ölçeği, bölgesel güven ölçeği ve seyahat niyeti ölçeği dört bölüm ve toplam 24 sorudan oluşmaktadır.
Araştırma sonucu sağlık turizminde elektronik ağızdan ağıza pazarlamanın yabancı hastaların bölgesel güven ve ülkeye seyahat niyeti üzerinde aynı yönlü olumlu bir etkisi olduğu saptanmıştır. Sağlık turizminde elektronik ağızdan ağıza pazarlamanın bölgesel güvenin %21’lik kısmını, seyahat niyetinin ise %13,7’lik kısmını açıkladığı görülmektedir. Farklı illerde ve ülke genelinde daha büyük örneklemler üzerinde yapılacak çalışmalar, sağlık turizminde elektronik ağızdan ağıza pazarlamaya dair daha kapsamlı sonuçlara ulaşılmasını sağlayacaktır.
MUSIC, POLITICS & PHILOSOPHY; HOW MUSIC IS PERCEIVED AS A POLITICAL TOOL
Authors: Abubakar Siddique Harun , Sidal Süleyman
Published: April 2022

Music is used by politicians as means to reach the masses by conveying succinctly their message and boosting their images. The state also uses music to preserve some of its memories as well. However, music and musicians have suffered at the hands of politicians when the music turns to criticize politicians or the standard norms in the state or society. Thus, Music can be either an ideological tool in the hands of the state or a symbol of critique that incurs state oppression. Historically, different examples show how important role music can play in the dissolution and collapse of a political organization as well as its establishment and construction. From Plato, More, Campanella to Khomeini, philosophers, thinkers, rulers, and politicians mention the significance of music in statehood. In this study, it is argued that this view can be seen as a projection of totalitarian thought within the historical line mentioned. In this context, although music is seen as a harmless act that is essentially non-political, depending on the preference of the individual or group, and a harmless act that is not inherently political, some thinkers consider it a disruptive act that can disrupt the social order and harmony, and encourage people's indifference or disobedience to political power, or even rebellion, therefore, it is perceived as a phenomenon that should be controlled and censored.

ÖDEME GÜÇLÜĞÜNE BAĞLI KARŞILANMAYAN RUHSAL TEDAVİ İHTİYACINI ETKİLEYEN FAKTÖRLERİN BELİRLENMESİ
Authors: GENÇ Gülşen , KURUTKAN Mehmet Nurullah
Published: April 2022

Çalışmanın amacı, sosyo-ekonomik faktörlerin ödeme güçlüğüne bağlı karşılanmayan ruhsal tedavi ihtiyaçları üzerindeki etkisini belirlemektir. Çalışmanın analizinde kullanılan parametreler, TÜİK (Türkiye İstatistik Kurumu)’den elde edilen “Sağlık Araştırması” anket verilerinden sağlanmıştır. Elde edilen değişkenlere farklılık ve binary lojistik regresyon analizi uygulanmıştır. Sosyo-ekonomik değişkenlerin ve depresyonun ödeme güçlüğüne bağlı karşılanmayan ruhsal tedavi ihtiyaçlarını etkileme derecesini tespit etmek amacıyla bir model oluşturulmuştur. Kurulan modelin analizinde binary lojistik regresyon analizi yapılmıştır. Karşılanmayan ruhsal tedavi ihtiyaçları sosyo-ekonomik değişkenlere göre farklılık arz etmektedir. Cinsiyet, yaş, hane geliri, sağlık güvencesine sahip olmak, bedensel ağrı durumu, genel sağlık durumu, depresyon hastalığı gibi faktörlerinin karşılanmayan ruhsal tedavi ihtiyaçlarına en çok etki eden faktörler olduğu sonucuna ulaşılmıştır. Ruhsal tedaviye ihtiyacı olduğu halde ödeme güçlüğü nedeniyle ihtiyacı karşılanmayan bireylerin daha çok dezavantajlı gruplarda yer alan bireyler olduğu ortaya çıkmaktadır. Bu bağlamda, ruhsal tedaviye ihtiyacı olan bireylerin ihtiyaçlarını karşılamaya yönelik müdahalelerin planlanması ve uygulanması, bireylerin toplumda yaşamını sürdürebilmesi için de önem arz etmektedir.

Cenários políticos-afetivos da mulher negra em contextos pós-coloniais: uma análise interseccional sobre obras de Buchi Emecheta
Authors: Peregrino Souto Maior Mendes Maria Elizabeth , Velloso Borges Pereira Ana Clara
Published: April 2022

O presente estudo almeja investigar, à luz das teorias interseccionais e dos estudos de gênero, quais opressões atingem as mulheres nigerianas retratadas pela escritora Buchi Emecheta nos romances As alegrias da maternidade (1979) e Cidadã de Segunda Classe (1974). Tal análise permite observar os efeitos do pós-colonialismo, da maternidade, do casamento e da raça na vida das personagens Nnu Ego e Adah, que saem de suas comunidades originárias em busca de melhores condições de vida em contextos urbanos. Visando a fundamentar as observações dispostas no artigo, foram utilizadas como principais aportes bibliográficos Crenshaw (1989), Hill Collins (2000), Kilomba (2019) e Hudson-Weems (2019). Ao alinhar os referenciais teóricos ao texto literário, o estudo busca compreender também as nuances transculturais que se apresentam nas narrativas de autoras africanas. Diante dessas duas narrativas, a importância do artigo é justificada pela necessidade de combater os estigmas sociais e antropológicos impostos às mulheres africanas.
A frase segundo os rascunhos: um trajeto entre o oral e o escrito
Authors: Boré Catherine , Bosderon Catherine
Published: April 2022

O artigo aborda o ponto de vista dos alunos sobre a língua tal como podemos apreendê-la a partir dos rascunhos. Designaremos assim as diferentes modalidades de aparecimento do texto a partir das retomadas orais e (re)formulações escritas e orais. O artigo, portanto, propõe-se a explorar a noção de frase nos rascunhos “em vias de se fazer”. Posterior a recuperação do status da frase como objeto escolar em sua perspectiva histórica de aparição, a análise se concentra no diálogo (e na produção simultânea) de duas díades de alunos (7 anos de idade e 5 meses) enquanto escrevem um texto ficcional. São as ocorrências meta-enunciativas da palavra “frase” nos diálogos dos escreventes que são analisadas a fim de compará-las com as frases escritas por eles. As mudanças que ocorrem entre a “frase” oral espontânea, a frase ditada e a frase escrita pontuada na produção de textual constituem nosso objeto de análise. Elas revelam o trajeto cognitivo dos escreventes nas diferentes etapas do processo de escritura, modificando a perspectiva de recepção dos rascunhos. Elas contribuem, assim, para lançar luz sobre as relações entre frase e texto, de uma forma diferente da literatura existente.PALAVRAS-CHAVE: Meta-enunciação; Frase; Textualização; Rascunho; Pontuação.

Authors: Sumari Regina
Published: April 2022

Este libro es una adaptación de una tesis presentada en la Universidad Nacional del Altiplano, El objetivo de la investigación fue evaluar la influencia del umbral lingüístico en la competencia lectora de estudiantes bilingües. El estudio se realizó con dos grupos de 27 estudiantes castellano-quechua y quechua-castellano de segundo grado de secundaria del INA 21 de Azángaro, en enfoque cuantitativo, tipo de investigación explicativa y diseño cuasi experimental con prueba de entrada y salida. El umbral lingüístico se determinó mediante pruebas de vocabulario receptivo y productivo, después de un programa de reforzamiento en lectura; la competencia lectora, mediante las pruebas de lectura del Ministerio de Educación; y la relación entre umbral lingüístico y competencia lectora, a través de la correlación de Pearson (r). Los resultados indican que todas las variables evaluadas fueron significativas (p < 0.05). El umbral lingüístico del grupo castellano-quechua fue mayor que el del grupo quechua-castellano, en un nivel avanzado vs. principiante, un vocabulario receptivo de 2130 vs. 975 de las 3000 palabras más frecuentes, y una cobertura léxica de 71.0 vs. 32.5%, respectivamente. La competencia lectora del grupo castellano-quechua fue mayor que la del grupo quechua-castellano, con un puntaje de 718 (satisfactorio) vs. 594 (en proceso), respectivamente. La correlación entre el umbral lingüístico y la competencia lectora fue alta (r = 0.76) y significativa (p < 0.05), evidenciando causalidad y asociación positiva directa entre las variables. A partir de los resultados se concluye que, el umbral lingüístico influye positivamente en la competencia lectora de estudiantes bilingües castellano-quechua y quechua-castellano, manifestándose con una brecha significativa en el logro de sus aprendizajes.

Published: April 2022

Este libro es una adaptación de una tesis presentada en la Universidad Andina Néstor Cáceres Velásquez de Juliaca, cuyo objetivo fue la evaluación de tres técnicas de fotopolimerización con diodo emisor de luz en la resistencia compresiva de resina compuesta de nanopartículas. En la Metodología el estudio, es de nivel explicativo, de corte transversal y cuasi-experimental, en los materiales y métodos se elaboraron sesenta cilindros de resina compuesta de nanopartículas de la marca 3M™ Filtek™ Z350 XT de 4 mm de diámetro por 8 mm de altura, los cuales se dividieron en tres grupos de 20 cilindros de resina compuesta cada uno, en donde cada grupo fue fotopolimerizado con las tres diferentes técnicas por 20 segundos con lámpara de diodo emisor de luz marca Woodpecker modelo LED.D; el grupo 1 (N°=20) fue polimerizado con técnica de luz intensa, el grupo 2 (N°=20) con técnica de luz en rampa y finalmente el grupo 3 (N°=20) con técnica de luz intermitente. Posteriormente fueron sometidas a cargas en kilogramos en la máquina para ensayos Marshall MA-75, donde se midió la resistencia compresivade los cilindros de resina. Los resultados se constituyeron en tablas utilizando estadística descriptiva, además de las pruebas estadísticas se empleó la prueba de ANOVA en donde se obtuvo P = 0.000 lo que indicó que si existen diferencias estadísticamente significativas entre las medias de los valores de las técnicas de fotopolimerización. Como conclusión tenemos que se presenta diferencias estadísticas en la resistencia comprensiva de la resina de nanopartículas, al ser fotopolimerizada con las tres diferentes técnicas, obteniéndose que la resistencia comprensiva con técnica en rampa tuvo valores mayoresque la luz intensa y luz intermitente respectivamente.
