CORRELATION BETWEEN SOCIAL STUDIES TEACHER CANDIDATES’ EPISTEMOLOGICAL BELIEFS AND THEIR INFORMATION LITERACY LEVELS
Authors: YORDAMLI Deniz , ŞENŞEKERCİ Erkan
Published: June 2021

It is evident that the school is the fundamental institution where both information literacy and sophisticated and flexible epistemological beliefs can be acquired as a competence subject. In this context, the main problem this study aims to address is the vital importance of educating pre-service teachers as information literates with sophisticated and flexible epistemological belief levels for teacher training institutions. Thus, this study aims to determine the epistemological belief and information literacy levels of Social Studies teacher candidates and to investigate whether there is a significant relationship between both levels. Conducted in a relational survey model, the study focuses on the effects of gender and class variables. Participants were 426 social studies teacher candidates studying at four different state universities located in the provinces of Bursa, Istanbul and Çanakkale in the academic year of 2018-2019. During the data collection process, we used the Epistemological Beliefs Scale originally developed by Schommer (1990), and the Information Literacy Scale developed by Adıgüzel (2011). The Epistemological Beliefs Scale utilised in our study was the Turkish version of the scale adapted into Turkish by Deryakulu & Büyüköztürk (2002) and whose validity and reliability analyses were made by Aydın et al. (2017). Apart from these two scales, the participants were also provided with a Personal Information Form to be filled in. Various statistical analyses and tests were applied to the collected data and the following basic findings were obtained: The epistemological beliefs and information literacy skills of social studies teacher candidates are at a high level. There was a low and moderate correlation between the epistemological beliefs of teacher candidates and their information literacy levels in the dimension of "belief that learning depends on effort" and "belief that learning depends on talent,” and a low correlation in the dimension of "belief that there is only one truth.”
Limited Space: Elderly People's Meanings of the City in the Time of Pandemic
Authors: Galkin Konstantin
Published: June 2021

The study examines the specifics of changes in the meanings of the city in interviews with older people. The author shows what restrictions in the use of material and social resources exist in urban spaces, how these restrictions are interrelated and how they create peculiarities in the interpretation of the meanings of cities by older people. The empirical basis of the study was 20 semi-structured interviews and 15 observation diaries with elderly people from St. Petersburg and Petrozavodsk, which were collected during the COVID-19 pandemic from April 14 to June 1, 2020. The key findings of the study relate to the different interpretations of urban spaces present in the locations where the study was conducted; secondly, how the limited material resources of the city and the perceived tightness of older people within one space affect social resources. In addition, the question is raised as to how the lack of material resources can be compensated through social resources, such as volunteer assistance. The presence of volunteers is limited in various cities, and restrictions on the provision of volunteer assistance are a serious problem for a large city of regional significance — Petrozavodsk.

Authors: Puspitarini Dewi Anggun , Purnama Prawira Aros , Dewi Isti Riana
Published: June 2021

This study aims to analyze and obtain empirical evidence of deceptive behavior as a moderating variable of trust in purchasing through e-commerce purchase intentions. The data of this research were obtained from the results of collecting a questionnaire of 100 respondents who were consumers who had made transactions through e-commerce sites. Testing the hypothesis in this study using the measurement model (Outer Model) and structural models (Inner Model) with the application of Partial Least Square (PLS). The PLS program used is SmartPLS version 3.02.8. The results of this study indicate that trust has a positive effect on purchase intentions. However, with deceptive behavior as moderation, deceptive behavior weakens the relationship between trust in purchasing through E-Commerce and purchase intention as a mediating variable. Purchase intention is proven to be a mediating variable that mediates trust in mentally buying. The government should be more assertive in handling cases of e-commerce crime that are rife to create security and comfort for e-commerce site users.

Purpose: This research aimed to observe the differences between respondents’ characteristics based on their career goals as part of employer brand, and to identify effective employer branding. It was important since many businesses failed to attract the best talent due to limited knowledge on organizational attractiveness and employer branding strategy. Design/methodology/approach: The data were collected through self-administered questionnaire. There were 16 items used to represent career goals attributes in employer branding. The data was ordered based on the characteristics’ relative importance and assigned points accordingly (the first rank is scored the highest = 6) and analyzed using a K-related samples test and weighted-mean average computation with ANOVA tables. K-independent samples and a One-Way ANOVA test to identify the differences of career goals preferences. Findings: Results showed that there were various significant different across respondents’ characteristics such as gender, marital status, academic achievement, work experience, and economic background. The differences between each group for the most and the least important career goals can still be observed. The findings for career goals items are generally consistent with the known theories of organizational attraction. Research limitation/implications: The data were collected from business school students. It is limited in that it may not have captured the reflections of potential employees groups in Indonesia whose characteristics combinations of experience and attitudes toward employer brand differed from the sample used. Applying these research findings should be done meticulously. Practical implications: This research offered an interesting insight on the relations of employer brand's attractiveness dimensions, career goals, and individual differences. Based on this research findings, organizations may consider emphasizing on the attributes that are attractive to high-achievers or to one specific gender. Originality/value: This research contributed to identifying how respondents perceive the dimensions ranking of employer brand attractiveness and analyzing the detail characteristics attractiveness (career goals) based on demographic variables.

Published: June 2021

This study addresses the peculiarities of the generation of slope movements in the context of road infrastructures and provide a predictive mapping of susceptibility to movements on slopes adjacent to road infrastructures (rockfalls). An inventory of slopes movements was mapped. From the development of the inventory of constant cases of mobilization that is used as a dependent variable, two statistical models can be obtained and compared for the same study area. One of them is based on the concept of frequency, whilst the other one is based on the application of a logistic regression. The results reveal the preponderant importance of lithology as a predictive variable, followed, at a considerable distance, by the slope gradient. Likewise, the importance of an unnatural and characteristic variable area of study, such as the presence of artificial cuts, is indicated as a causative factor. The results show a high degree of coincidence between the tendency of susceptibility predicted by the model, and the effective presence of empirical mobilization signs on the slopes, with Area Under Curve (AUC) values for Receiver Operating Characteristics (ROC) around 0.8.

Published: June 2021

Overt hyperthyroidism during pregnancy is associated with risk of maternal-fetal complications. The antithyroid drugs (ATD) have a potential risk for teratogenic effects and fetal–neonatal hy-pothyroidism. This study evaluated ATD treatment and thyroid function control during preg-nancy, and pregnancy outcome in women with hyperthyroidism. Patients and methods: retro-spective analysis of 36 single fetus pregnancies in 29 consecutive women (median age 30.3 ± 4.7 years) with hyperthyroidism diagnosed before or during pregnancy; a control group of 39 healthy euthyroid pregnant women was used. Results: 26 women had Graves’ disease (GD, 33 pregnan-cies), 1 had a hyperfunctioning autonomous nodule, 2 had gestational transient thyrotoxicosis (GTT). Methimazole (MMI) was administered in 22 pregnancies (78.5%), Propylthiouracil (PTU) in 2 (7.1%), switch from MMI to PTU in 4 (14.2%), no treatment in 8 pregnancies (3 with subclinical hyperthyroidism, 5 euthyroid with previous GD remission before conception). One spontaneous abortion at 5 weeks (3.4% of pregnancies) and 1 premature delivery at 32 weeks with perinatal death in 24h (3.4%) were recorded in 2 of the 8 pregnancies of GD patients diagnosed shortly before (< 6 weeks) or during gestation. In women treated more than 6 months until conception (20 pregnancies): a) median ATD doses were lower than those in women diagnosed shortly before or during pregnancy; b) ATD was withdrawn in 40% of pregnancies in trimester (T) I, all on MMI < 10 mg/day (relapse in 14.2%), and in up to 55% in TIII; c) TSH level was below normal in 37%, 35% and 22% of pregnancies in T I, II and III respectively; FT4 was increased in 5.8% (T I) and sub-normal in 11.75% in TII and III; d) one fetal death due to a true umbilical cord knot was recorded. Hyperthyroidism relapsed postpartum in 83% of GD patients (at median 3 ± 2.6 months). One child had neonatal hyperthyroidism (3.3% of live children in GD women) and a small atrial sept defect (4% of live children in ATD treated women). Mean birth weight did not differ from that of the control group. Conclusion. In hyperthyroid women with long-term ATD control before con-ception, drugs could be withdrawn in TI in a third of them, and fetal complications were rare. Frequent serum TSH and FT4 monitoring is needed in order to maintain optimal thyroid function during pregnancy.

Published: June 2021

Most hair relaxers or straighteners used for Afro-textured hair have a pH above 11. This pH, according to international occupational health and safety guidelines, is corrosive to the skin. Further, relaxers are associated with a 3-6 times increased risk of alopecia. The skin also gets into contact with these hair straightening products during application resulting in skin irritation. Using animals as test subjects to determine these products' potential risk and safety margin is standard practice; however, with the European Union (EU) ban on animal testing, the testing method needs to be replaced by newer in vitro laboratory technologies. This study used previously and newly established in vitro cell-based technologies and human-skin derived cells as laboratory models to evaluate relaxer-induced cytotoxicity. These technologies include endpoint (MTT, CCK-8 and flow cytometry) and real-time assays (real-time cell analysis (RTCA) and extracellular flux analysis). Cellular toxicity was evident following treatment of keratinocytes and fibroblasts with acceptable concentrations of thioglycolic acid (TGA, HSCH2COOH), ammonium bisulphite (NH4HSO3), lithium hydroxide (LiOH) and sodium hydroxide (NaOH) based relaxers. Real-time assays showed significant reductions (P<0.001) in cell index and ATP production following treatment of keratinocytes with as little as one-tenth of the acceptable concentrations. Increased apoptosis (47.9%, 58.0%, 76.7% and 80.3%) also occurred in cells after treatment with TGA, NH4HSO3, NaOH and LiOH, respectively. In conclusion, this study demonstrated that using skin cells in conjunction with advanced cell-based technologies could serve as alternatives to laboratory animals for accessing the toxicity margin of hair relaxers, straighteners and other cosmetics.

Published: June 2021

The lower Cambrian Niutitang shales, as one of target intervals with the greatest potential for shale gas exploration and development, have attracted much attention. Nevertheless, the organic matter enrichment mechanisms of the lower Cambrian Niutitang shales need further study, especially in the hydrothermal active zone. In this study, samples from ND1 well in western Hubei Province, middle Yangtze region, South China, were investigated for the controlling factors of organic matter accumulation of Lower Cambrian Niutitang shales by detailed petrographic, mineralogic, and geochemical proxies. The results show that hydrothermal activity and sea level fluctuation controlled the redox conditions and paleoproductivity of seawater and ultimately controlled the organic matter accumulation of Niutitang formation. In the Niu-1 member, the intense hydrothermal events lead to a suboxic to anoxic environment, which is conducive to the organic matter preservation. However, low sea level strengthens the restriction of water mass and reduced nutrient upwelling into the shelf, leading to decreased marine primary productivity, which was ultimately responsible for depleted organic matter accumulation in the Niu-1 member. In the Niu-2 member, the anoxic-euxinic environment and high paleoproductivity, driven by continuous hydrothermal activity and rising sea level, were the main factors controlling the enrichment of organic matter. In the Niu-3 member, the dysoxic to oxic condition plus low primary productivity, caused by the disappearance of hydrothermal activities and sea-level fall, resulted in the unfavorable organic matter accumulation. The results of this paper enrich the model of organic matter enrichment in the lower Cambrian black shale in the middle Yangtze region.
Das vidas vividas às vidas contadas
Authors: Menezes Victória
Published: June 2021

O trabalho em tela dedica-se à discussão concernente à formação de professores de Geografia, com enfoque na licenciatura. Busca promover uma discussão acerca do quadro atual da formação inicial a fim de destacar algumas problemáticas que devem ser revistas. A partir disso, visa apresentar o método (auto)biográfico como uma proposição a ser introduzida na licenciatura em Geografia, uma vez que carrega consigo uma outra epistemologia de formação. Epistemologia esta, assentada em determinados pressupostos, que compreende a formação do professor como um processo desenvolvido ao longo da trajetória de vida. Nesse sentido, há o reconhecimento do indivíduo como o sujeito de sua formação, o qual assume sua autonomia neste processo por conceber o percurso de vida como um percurso formativo. São as trajetórias de vida pessoal, de escolarização, de formação acadêmica e de atuação profissional que abrangem os distintos saberes docentes. Este método pode se concretizar por meio de narrativas (auto)biográficas de licenciandos que, ao revelarem suas memórias do passado ressignificadas no presente, explicitam as raízes de suas representações e concepções a respeito da docência em Geografia, o que pode conduzir às suas práticas de ensino. Portanto, o método (auto)biográfico é potente por proporcionar processos autoformativos e heteroformativos, considerar a história de vida como formadora e fornecer subsídios para a compreensão da construção da professoralidade em Geografia de cada sujeito docente.
Narrativas autobiográficas e histórias de vida na formação do professor de Geografia
Authors: Silva Maria
Published: June 2021

Esse artigo tem como objetivo a análise das contribuições das narrativas autobiográficas, através das histórias de vida, para a formação do professor de Geografia, numa perspectiva de compreender como o trabalho com histórias de vida na educação, principalmente na formação inicial, contribui para a preparação de profissionais crítico-reflexivos. Compreendendo que a formação do professor de Geografia na atualidade precisa estar alinhada com uma série de demandas sociais, da escola e da própria profissão docente, esse trabalho se propõe a discutir as narrativas autobiográficas como um instrumento de contribuição para uma formação inicial que considere e valorize as histórias de vida dos sujeitos, levando-os a refletir acerca de sua própria trajetória para a construção do pensamento espacial, tomando como base os conceitos geográficos e as vivências cotidianas. Desta forma, ao utilizar narrativas autobiográficas em pesquisas e na formação compreende-se que se abre possibilidades e caminhos para que o aluno de licenciatura possa compreender sua própria formação com base nas diferentes relações que ele constrói ao longo de sua vida e principalmente no campo profissional, ajudando-o a tomar consciência de si mesmos enquanto futuro professore. Portanto, compreende-se a formação docente como um processo contínuo, que tem início antes mesmo do ingresso no curso de licenciatura e que não se finda ao se obter o diploma, mas ultrapassa o ambiente acadêmico, sendo construído diariamente através das experiências que dão sentido à vida do sujeito e constroem a sua identidade.

Published: June 2021

Wireless sensor networks (WSNs) have fabulous attributes to collect data by sensing the surrounding environment. WSNs have a large number of applications that are facing challenges of routing, security, deployment, prolonged lifetime, data computation, and localization. To achieve the high-level performance of WSNs, many researchers have proposed various computational Intelligence (CI) based algorithms for the above-mentioned challenges. The procedure to determine the location of the target node is called node localization. It is easy to determine the coordinates of static nodes accurately but challenging task for the mobile nodes. Localization accuracy directly affects the WSN’s performance. In this paper, a range-based and distributed method are proposed by using the application of the Salp Swarm Algorithm (SSA), and the simulation results are compared with existing approaches such as Particle swarm Optimization (PSO) and H-best Particle Swarm Optimization (HPSO). In this paper, a single mobile anchor node as a reference node traversing the entire network in the Hilbert path and localize the mobile target nodes that are randomly deployed in the networking area. The primary goal behind selecting the Hilbert trajectory is to reduce the issue of LoS. The simulation results show that the proposed method has low localization error and an approximate double number of localized nodes with less computing time as compared to existing methods.

Published: June 2021

Traumatic Brain Injury (TBI) is the most prevalent of all head injuries, and based on the severity of the injury, it may result in chronic neurologic and cognitive deficits. Microglia play an essential role in homeostasis and diseases of the central nervous system. We hypothesize that microglia may play a beneficial or detrimental role in TBI depending on their state of activation and duration.In the present study, we evaluated whether TBI results in a spatiotemporal change in microglia phenotype and whether it affects sensory-motor or learning and memory functions in male C57BL/6 mice. We used a panel of neurological and behavioral tests and a multi-color flow cytometry-based data analysis followed by unsupervised clustering to evaluate isolated microglia from injured brain tissue. We characterized several microglial phenotypes and their association with cognitive deficits. TBI results in a spatiotemporal increase in highly activated microglia that correlated negatively with spatial learning and memory at 35 days post-injury. These observations could define therapeutic windows and accelerate translational research to improve patient outcomes.
Spectral characterization of dissolved organic matter along trophic gradients: Potential indicators of eutrophication of plateau lakes in Southwest China
Authors: Guan Yuying , Han Ruiming , Jia Nannan , Huo Da , Yu Gongliang
Published: June 2021

Dissolved organic matter (DOM) acts as a chemical intermediary between terrestrial and lacustrine ecosystems and significantly affects the structure and function of lakes. The optical characteristics of DOM have been widely used to estimate the water quality. However, little is known about its absorption and fluorescence under different trophic states. Especially, comparative research is needed among gradient eutrophic level of plateau lakes when considering their special characteristics. A total of 119 water samples were collected in the Erhai watershed from November 2018 to July 2019 to investigate the optical properties of DOM depending on the trophic state using ultraviolet–visible spectroscopy and parallel factor analysis of the excitation–emission matrix. The water quality conditions in the Erhai watershed were classified using the trophic state index (TSI; 31 < TSI < 67). The DOM is largely autochthonous and includes tyrosine-like protein (C1), tryptophan-like protein (C2), and humic-like compounds (C3). Except for an apparent trend of decreasing slope ratio (SR) (p < 0.01), both absorption coefficient at 254 nm and fluorescence intensity increase with the rising trophic state (p < 0.01). In this study, new models (R2aCDOM(254) = 0.762; R2 Fn(355) = 0.705, p < 0.01) basing on significant correlations between the TSI and aCDOM(254) and Fn(355) were established to predict the trophic state. The results of this study demonstrate that the effects of nutrients and environmental factors (pH and water temperature) on DOM vary depending on the trophic state and that the pH plays the main role in DOM production. Our analyses highlight the importance of DOM in aquatic ecosystems and the correlation between TSI and the optical properties of DOM. Our research unmasks the strong linkage between optical parameters of DOM and freshwater quality by applying neural network prediction.

Background: Brain abscess due to the Nocardia genus is rarely reported and it is usually found in immunocompromised patients. Treatment of Nocardia brain abscess is troublesome and requires consideration of the severity of the underlying systemic disease. The difficulties in identifying the bacterium and the frequent delay in initiating adequate therapy often influence the prognosis of patients.Case presentation: Here, we report a rare case of brain abscess caused by Nocardia farcinica. The patient’s medical history was complicated, he was hospitalized for several times, but no pathogens were found. At last, bacterial was found in culture of brain abscess puncture fluid, the colony was identified as Nocardia farcinica by mass spectrometry. Targeted antibiotic treatment was implemented, brain abscess tended to alleviate, but the patient eventually developed fungal pneumonia and died of acute respiratory distress syndrome (ARDS). Conclusion: brain abscess caused by Nocardia farcinica can be appear in non-immunocompromised individuals. Early diagnosis, reasonable surgical intervention, and targeted antibiotic treatment are critical for Nocardia brain abscess treatment. In the treatment of Nocardia brain abscess, we should pay attention to the changes of patients' immunity and avoid infection with other pathogens, especially fungi.

BackgroundEstimates of future survival can be a key evidence source when deciding if a medical treatment should be funded. Current practice is to use standard parametric models for generating extrapolations. Several emerging, more flexible, survival models are available which can provide improved within-sample fit. This study aimed to assess if these emerging practice models also provided improved extrapolations.MethodsBoth a simulation study and a case-study were used to assess the goodness of fit of five classes of survival model. These were: current practice models, Royston Parmar models (RPMs), Fractional polynomials (FPs), Generalised additive models (GAMs), and Dynamic survival models (DSMs). The simulation study used a mixture-Weibull model as the data-generating mechanism with varying lengths of follow-up and sample sizes. The case-study was long-term follow-up of a prostate cancer trial. For both studies, models were fit to an early data-cut of the data, and extrapolations compared to the known long-term follow-up.ResultsThe emerging practice models provided better within-sample fit than current practice models. For data-rich simulation scenarios (large sample sizes or long follow-up), the GAMs and DSMs provided improved extrapolations compared with current practice. Extrapolations from FPs were always very poor whilst those from RPMs were similar to current practice. With short follow-up all the models struggled to provide useful extrapolations. In the case-study all the models provided very similar estimates, but extrapolations were all poor as no model was able to capture a turning-point during the extrapolated period. ConclusionsGood within-sample fit does not guarantee good extrapolation performance. Both GAMs and DSMs may be considered as candidate extrapolation models in addition to current practice. Further research into when these flexible models are most useful, and the role of external evidence to improve extrapolations is required.
Surgical Masks Impair People's Ability To Accurately Classify Emotional Expressions, Except For Anger

Published: June 2021

Background

Recently, the need to continuously wear surgical masks in everyday life has drawn the attention of neuroscientists and psychologists to the negative effects of face covering on social processing. A very recent but not very homogeneous literature has highlighted large costs in the ability to recognize emotions.
Methods

Here it was investigated how surgical masks covering impaired the recognition of facial mimicry in a large group of 220 undergraduate Italian students. Sex differences in emotion recognition were also observed in 2 subgroups of 94 age-matched participants. Subjects were presented with 112 pictures displaying the faces of 8 actors (4 women and 4 men) wearing or not wearing real facemasks, and expressing 7 emotional states (neutrality, surprise, happiness, sadness, disgust, anger and fear). The task consisted in categorizing the emotion while indicating the recognizability degree with a 3-point Likert scale. Scores underwent repeated measures ANOVAs.
Results

Overall, face masking reduced emotion recognition by 31%. All emotions were affected by mask covering except for anger. Face covering was most detrimental for sadness and disgust, both relying on mouth and nose inspection. Women showed a better performance for subtle expressions such as surprise and sadness, both in masked and natural conditions, and men for fear recognition (in natural but especially masked conditions).
Conclusions

Anger display was unaffected by masking, since corrugated forehead and frowning eyebrows were clearly exposed. Unlike digitally created masks, real masks were able to show inhalation-related sucking associated with startle reaction (in surprise, and especially fear expressions), thus providing further cues for emotion recognition.

Background: Saline hydration with addition of mannitol have commonly being strategy to avoid cisplatin induced acute kidney injury. While the initial reports demonstrated that mannitol diuresis decreased cisplatin induced renal injury, others have shown renal injury to be worsened.Objective: To compare the risk of acute kidney injury in cancer patients receiving high dose cisplatin with addition and without addition of mannitol.Method: This was an ambispective cohort study based on consecutive sampling at Cipto Mangunkusumo General Hospital and Mochtar Riady Comprehensive Cancer Centre (MRCCC) Siloam Hospitals. The data was obtained from September 2017 to February 2018. The choice of mannitol administration based on responsible physician clinical judgement. The outcome was any increment more than 0,3 mg/dl or 1,5 times from baseline of serum creatinine. Analysis was done by using SPSS statistic for univariate, bivariate and multivariate logistic regression to obtain crude risk ratio and adjusted risk ratio of cisplatin induced acute kidney injury probability of mannitol addition on hydration.Result: Data from 110 patients (57,3% male) with a median age of 44,5 years (range 19 to 60 years) were collected; 47 received saline alone and 63 received saline with addition of mannitol. Acute kidney injury were higher in mannitol vs non mannitol group. Bivariate analysis showed higher probability of post chemotherapy AKI in mannitol group (RR 2,168; 95% CI 0,839-5,6). On multivariate analysis the adjusted RR was 3,52 (95% CI 1,11-11,162; p value = 0,033) by controlling age.Conclusion: The addition of mannitol on hydration had higher risk of AKI after high dose cisplatin chemotherapy.
