Tone and genes: New cross-linguistic data and methods support the weak negative effect of the “derived” allele of ASPM on tone, but not of Microcephalin
Authors: Dediu Dan
Published: June 2021

While it is generally accepted that language and speech have genetic foundations, and that the widespread inter-individual variation observed in many of their aspects is partly driven by variation in genes, it is much less clear if differences between languages may also be partly rooted in our genes. One such proposal is that the population frequencies of the so-called “derived” alleles of two genes involved in brain growth and development,ASPMandMicrocephalin, are related to the probability of speaking a tone language or not. The original study introducing this proposal used a cross-linguistic statistical approach, showing that these associations are “special” when compared with many other possible relationships between genetic variants and linguistic features. Recent experimental evidence supports strongly a negative effect of the “derived” allele ofASPMon tone perception and/or processing within individuals, but failed to find any effect forMicrocephalin. Motivated by these experimental findings, I conduct here a cross-linguistic statistical test, using a larger and updated dataset of 175 samples from 129 unique (meta)populations, and a battery of methods including mixed-effects regression (Bayesian and maximum-likelihood), mediation and path analysis, decision trees and random forests, using permutations and restricted sampling to control for the confounding effects of genealogy (language families) and contact (macroareas). Overall, the results support a negative weak effect ofASPM-D against the presence of tone above and beyond the strong confounding influences of genealogy and contact, but they suggest that the original association between tone andMCPH1might have been a false positive, explained by differences between populations and languages within and outside Africa. Thus, these cross-linguistic population-scale statistical results are fully consonant with the inter-individual-level experimental results, and suggest that the observed linguistic diversity may be, at least in some cases, partly driven by genetic diversity.

Methicillin-resistant Staphylococcus aureus (MRSA) has long been known as a major cause of hospital-acquired (HA-MRSA) infections worldwide. For the past twenty years, an increasing number of studies have described its emergence in the community as well. In Portugal, a country with a high-prevalence of HA-MRSA, there are only limited data available on the epidemiology of MRSA in the community. We studied the prevalence of S. aureus and MRSA colonization among healthy adults in Portugal. Between February 2015 and December 2016, a longitudinal study was conducted in which 87 adults aged 25–50 years old were followed for six months. For each participant nasopharyngeal, oropharyngeal and saliva samples were obtained monthly and, in some cases, weekly. A total of 1,578 samples (n = 526 for each sampling site) were examined for the presence of S. aureus and MRSA by classical culture-based methods. Fifty-seven adults (65.5%) carried S. aureus at least once during the six months period of the study: 19.5% were persistent S. aureus carriers and 46.0% were intermittent carriers. Carriage rates per sampling site were 20.5% in nasopharynx, 18.3% in oropharynx, and 13.5% in saliva. Simultaneous screening of the three sampling sites increased detection of S. aureus, which overall occurred in 34.4% of the 526 sampling time-points. No MRSA were isolated. In conclusion, this study adds novel information about the MRSA scenario in the Portuguese community. Our results indicate that, in Portugal, MRSA does not seem to circulate among healthy adults without risk factors and therefore this age group does not constitute, at the current time, a reservoir of MRSA in the community.

Published: June 2021

The study is focused on impact of manure application, rice varieties and water management on greenhouse gas (GHG) emissions from paddy rice soil in pot experiment. The objectives of this study were a) to assess the effect of different types of manure amendments and rice varieties on greenhouse gas emissions and b) to determine the optimum manure application rate to increase rice yield while mitigating GHG emissions under alternate wetting and drying irrigation in paddy rice production. The first pot experiment was conducted at the Department of Agronomy, Yezin Agricultural University, Myanmar, in the wet season from June to October 2016. Two different organic manures (compost and cow dung) and control (no manure), and two rice varieties; Manawthukha (135 days) and IR-50 (115 days), were tested. The results showed that cumulative CH4 emission from Manawthukha (1.084 g CH4 kg-1 soil) was significantly higher than that from IR-50 (0.683 g CH4 kg-1 soil) (P<0.0046) with yield increase (P<0.0164) because of the longer growth duration of the former. In contrast, higher cumulative nitrous oxide emissions were found for IR-50 (2.644 mg N2O kg-1 soil) than for Manawthukha (2.585 mg N2O kg-1 soil). However, IR-50 showed less global warming potential (GWP) than Manawthukha (P<0.0050). Although not significant, the numerically lowest CH4 and N2O emissions were observed in the cow dung manure treatment (0.808 g CH4 kg-1 soil, 2.135 mg N2O kg-1 soil) compared to those of the control and compost. To determine the effect of water management and organic manures on greenhouse gas emissions, second pot experiments were conducted in Madaya township during the dry and wet seasons from February to October 2017. Two water management practices {continuous flooding (CF) and alternate wetting and drying (AWD)} and four cow dung manure rates {(1) 0 (2) 2.5 t ha-1 (3) 5 t ha-1 (4) 7.5 t ha-1} were tested. The different cow dung manure rates did not significantly affect grain yield or greenhouse gas emissions in this experiment. Across the manure treatments, AWD irrigation significantly reduced CH4 emissions by 70% during the dry season and 66% during the wet season. Although a relative increase in N2O emissions under AWD was observed in both rice seasons, the global warming potential was significantly reduced in AWD compared to CF in both seasons (P<0.0002, P<0.0000) according to reduced emission in CH4. Therefore, AWD is the effective mitigation practice for reducing GWP without compromising rice yield while manure amendment had no significant effect on GHG emission from paddy rice field. Besides, AWD saved water about 10% in dry season and 19% in wet season.
Two novel truncating variants in UBAP1 are responsible for hereditary spastic paraplegia

Published: June 2021

Hereditary spastic paraplegias (HSPs) are a group of rare neurodegenerative disorders. HSPs are complex disorders and are clinically and genetically heterogeneous. To date, more than 80 genes or genetic loci have been reported to be responsible for HSPs in a Mendelian-dependent manner. Most recently, ubiquitin-associated protein 1 (UBAP1) has been recognized to be involved in HSP. Here, we identified novel protein truncating variants in two families with pure form of HSP. A novel deletion (c.468_469delTG) in the UBAP1 gene was found in the first family, whereas a nonsense variant (c.512T>G) was ascertained in the second family. The variants were confirmed in all patients but were not detected in unaffected family members. The mutations resulted in truncated proteins of UBAP1. The variants did not result in different subcellular localizations in neuro-2a cells. However, each of the two variants impaired neurite outgrowth. Taken together, our findings expand the pathogenic spectrum of UBAP1 variants in HSP.

A Self-study Exploration of Early Career Teacher Burnout and the Adaptive Strategies of Experienced Teachers
Authors:   Deakin University, Melbourne, Hogan Jarrod P. , White Peta J. ,   Deakin University, Melbourne
Published: June 2021

Isolation, organisational pressures, and role-related distress, can result in teachers, particularly early career teachers (ECTs), experiencing greater risk of burnout. For many ECTs, a lack of practical strategies for dealing with these conditions contributes to this. Using self-study methodology, this research unpacks why ECTs experience burnout, identifies adaptive strategies that experienced teachers use, and discusses the applicability of these practices for ECTs. Conversations between an ECT and three experienced teachers provided alternate lenses to apply reflective unpacking of adaptive strategies. The findings illustrate how the risk of burnout for ECTs is increased by challenging student behaviour, isolation, a lack of collegiality and engagement with professional networks, and being overloaded with responsibilities. The findings also suggest that being overworked is less of a contributing factor to burnout than feeling disconnected from one’s school, peers, and community. Adaptive strategies for alleviating the effects of burnout were explored and recommendations for practice presented.
Towards a social pedagogic approach for social care
Authors: Cameron Claire , Moss Peter , Petrie Pat
Published: June 2021

The term ‘social care’ has come to be applied in England to a variety of policies and services for children and adults deemed, for a variety of reasons, in need of support and assistance. The field to which it is applied is widely recognised to be in crisis, as demand grows, funding lags and a poorly qualified, low-paid workforce shows increasing signs of strain. The article argues that a further dimension to the crisis is the very term ‘social care’. It has little substance and is of limited value in addressing the practice involved in working with children, young people and adults, while its continued use has encouraged a simplified and commodified understanding of what this work entails. The article introduces an alternative concept – social pedagogy – long established and well developed in continental Europe, which, it is argued, could provide a more substantial basis for everyday practice, and a strong foundation for future policy, including reforming the workforce. The conclusion questions whether ‘social care’ can play any useful role in the evolution of policy and practice, discussing some issues that a turn to a social pedagogic approach might raise.
Teacher education for sustainable development within national frameworks: Squaring the circle from a German perspective
Authors: Christoforatou Ellen
Published: June 2021

This article deals with the question of how teacher education and teacher training in Germany – of which many aspects have been fragmentized – can nevertheless provide teachers with an adequate opportunity to systematically develop their professional competences in the field of education for sustainable development (ESD). Based on current education policy goals and relevant empirical research, the article offers a theory intended to cause coherence between three phases of teacher education and training in Germany, thereby integrating academic theory and ESD practice more consistently. Particular attention is given to teacher educators, educational managers, researchers and decision makers, who often have not acquired solid expertise in the specific area of ESD themselves. Their active inclusion is the key success factor in the intrinsic processes regarding organizational development at teacher education institutions.

Fronteira agrícola e ameaças às Unidades de Conservação no Cerrado
Authors: Oliveira Karla Rosane Aguiar
Published: June 2021

O Cerrado passa atualmente por uma intensa mudança de sua paisagem em função do avanço da fronteira agrícola. O modelo de desenvolvimento adotado pelo Brasil especialmente a partir dos anos 1960 incentivou a modernização conservadora da agricultura e promoveu o “pacto do agronegócio”, que se intensifica mediante um aparato ideológico articulado denominado agroestratégias. Este conjunto coordenado de ações busca influenciar políticas governamentais em prol do aumento em áreas para produção de commodities. As Unidades de Conservação no bioma Cerrado assumem um importante papel para a conservação da biodiversidade frente ao avanço da fronteira agrícola. Porém, as agroestratégias impõem ameaças a esses territórios, com a possibilidade de redução de limites territoriais, recategorização e diminuição do grau protetivo destas áreas. Este artigo tem como objetivo discutir as transformações territoriais oriundas da fronteira agrícola no Cerrado e da atuação das agroestratégias sobre os territórios destinados à conservação da biodiversidade, a partir do caso de desafetação do Parque Nacional das Nascentes do Rio Parnaíba, situado na fronteira entre os estados do Maranhão, Tocantins, Piauí e Bahia, e uma das regiões com maior produção agrícola do país.
Contemporary Political and Media Discourses on Immigrants
Authors: Stuardo-Concha Miguel , Soler-Campo Sandra , Riera-Retamero Marina
Published: June 2021

In this research we review academic publications on media and political discourse about migration published in Spain between 2014 and 2019. The review has been carried out following the principles of the Rapid Review and Rapid Evidence Assessment of the Literature applied to discourse analytical research. The researchers have posed three main questions: a) Which representation of migrants and migration has been described in Spain during the last 5 years? b) Which particularities can be observed in the representation of migrant women? c) How are migrant children represented? Once the selection criteria have been applied, a final corpus of 18 recents publications has been selected. The researchers have found diverse and complex nuances in the discourse about immigration in Spain, both in the media and in political discourse. There are also relevant silences in the sphere of media discourse and little research addressing specifically the discourse on migrant women, children and the contemporary anti-migration discourse in the media and political sphere.
La agenda que queda fuera de los medios. Desinformación y «fact-checking» sobre (in)migración
Authors: Magallon-Rosa Raul
Published: June 2021

El objetivo de este trabajo es analizar cómo los bulos sobre inmigración se utilizan como herramienta de difusión de una problemática, el discurso xenófobo, que en la mayoría de ocasiones queda fuera del alcance de los medios tradicionales. Sin embargo, este tipo de desinformación acaba afectando a la percepción que transmiten los medios sobre esta problemática.
La propuesta diferente de esta investigación está en la combinación de datos públicos —los barómetros del Centro de Investigaciones Sociológicas— con la base de datos interna de bulos y desmentidos que han desarrollado desde la organización periodística Maldita entre 2017 y 2019. Se estudia la evolución de la agenda sobre (in)migración desde un punto de vista de reciente investigación, no a través de su correspondencia con los medios de comunicación sino de su relación de convergencia con las redes sociales y, en concreto, con las nuevas formas de desinformación.
“He crecido aquí, es diferente”. Experiencias y trayectorias vitales de los/as descendientes de migrantes chinos en España
Authors: Lamas Abraira Laura
Published: June 2021

Este artículo explora las experiencias y trayectorias de los/as descendientes de migrantes chinos en España a partir de una perspectiva de curso vital: desde su infancia temprana, hasta su condición actual como jóvenes adultos/as. A través de una investigación etnográfica y en base a los testimonios en primera persona de los/as informantes, se analiza el posicionamiento e interacción de estos en su entorno familiar y en el contexto social más amplio, así como los factores que los condicionan. Familia, cuidados y diversas nociones de la ‘diferencia’ vertebran su relato aunando recuerdos, percepciones y expectativas en tiempo pasado, presente y futuro en las que referencias a lo ‘español’ y lo ‘chino’ son constantes. En base a la información obtenida, se subraya la necesidad de abogar por estudios que aporten una visión no fragmentada de las trayectorias de los/as descendientes de familias migrantes y un mayor énfasis en la noción de interconexión.
Agencia y polivictimización en infancia migrante: analizando percepciones profesionales
Authors: Pavez-Soto Iskra , Poblete-Godoy Daniela , Alfaro-Contreras Carmen
Published: June 2021

El propósito principal de este artículo es revisar y comparar los conceptos de polivictimización y agencia de la infancia migrante. La noción de agencia remite al clásico debate teórico entre agencia y estructura dentro de las ciencias sociales introduciendo distinciones conceptuales y analíticas entre las diversas formas de agencia infantil en los procesos migratorios. Mediante el método cualitativo, se realizaron entrevistas semiestructuradas a profesionales del área de los servicios sociales, educación y salud, para conocer su percepción sobre la agencia infantil. Se concluye que las percepciones profesionales sobre la agencia infantil migrante se inscriben en perspectivas reduccionistas, que, desde la sumisión a la agresión, se basan en visiones culturalistas y estereotipadas en torno a la edad, el sexo-género o la nacionalidad. Por este motivo, urge visibilizar la agencia infantil libre de juicios estereotipados.
Engaging Politically Disenfranchised Students in Governance
Authors: Nir Esther , Musial Jennifer
Published: June 2021

New Jersey City University is an urban, Minority- and Hispanic-Serving Institution with a First-Generation-to-College, commuter, and immigrant student population. How can we engage our students who feel powerless, distrustful, or even threatened by government actors in governance? Will perceptions of governance change with increased exposure to political elites in their communities? Using Community Engaged Learning methods, we asked students to attend civic meetings and courtrooms to observe the inner workings of governance and engage in dialogue with political elites. Journals and surveys reveal that students deconstructed pre-conceived notions of powerlessness, humanized government actors, and became hopeful about change in their communities.
Low-Stakes Quizzes Improve Learning and Reduce Overconfidence in College Students
Authors: Kenney Kevin L , Bailey Heather
Published: June 2021

Retrieval practice is a straightforward and effective way to improve student learning, and its efficacy has been demonstrated repeatedly in the laboratory and in the classroom. In the current study, we implemented retrieval practice in the form of daily reviews in the classroom. Students (N = 47) in a cognitive psychology course completed a daily review at the beginning of each class. These consisted of 2-4 questions that encouraged students to practice retrieving material covered in lectures from the previous week. Then at the end of the semester, students took a comprehensive final exam consisting of content that was either on a daily review, a unit exam, both or neither. We replicated previous work such that retrieval practice improved memory. Specifically, we found that students performed significantly better on questions whose information had been covered on both a daily review and unit exam. However, student performance did not differ amongst items covered only on a daily review, a unit exam, or on neither. Additionally, we extended previous work and found that students were significantly less overconfident for information covered on both a daily review and unit exam. The current results indicate that retrieval practice helps college students remember material over the course of a semester and also improves their ability to evaluate their own knowledge of the material.

In multimodal communication courses foregrounding history, archive, and visual culture studies, the form of the audio guide offers a useful medium for students to create inventive and theoretically rigorous projects.
Balancing Grace
Authors: Fecske Courtney J. W.
Published: June 2021

Before handing out my midterm exam the Thursday before Spring Break, the unease in the classroom was palpable. I questioned, is it the right thing to do to give a midterm exam now? Two days prior we learned online instruction would begin the week after spring break for the week and possibly longer. This was an unprecedented scenario. I never took a seminar titled, How to Continue Teaching During a Pandemic. I resolved myself with the attitude of we’ll get through this together; let’s get it done. Before passing out exams, I informally assessed students to see how many had taken an online course before, few hands raised. I then asked how everyone was feeling in regard to our inevitable online transition. Students expressed anxiety and worry because they had never taken a class titled, How to Continue to Learn During a Pandemic. As educators as we move ahead to an uncertain culture of learning, we must strive to listen and learn, grow in our pedagogies, and balance grace and flexibility with expectation.
Introduction to the Special Issue on 3D Methodologies in Mediterranean Archaeology
Authors: Notarian Matthew
Published: June 2021

This issue brings together several papers originally presented at the 2019 annual meeting of the Archaeological Institute of America in a panel entitled, “Three-Dimensional Archaeology Comes of Age.” This collection takes stock of a decade’s worth of groundbreaking transformation in archaeological practices with a focus on the ancient Mediterranean. Over this time, a subtle transition has occurred in which contentious debates over the value and practicality of 3D tools, such as photogrammetry, 3D scanning, 3D reconstruction, and virtual reality (VR), have given way to an emergent consensus that these constitute a new and important class of recording and heuristic instruments. Rather than seek to cover this fundamental shift in a comprehensive matter, this issue presents a characteristic cross-section of current archaeological research-based on three-dimensional computational methodologies. The content cuts across some 3,000 years of Mediterranean archaeology, from the Aegean Bronze Age to the later Roman Empire, underlining the discipline-wide impact of this methodological revolution. It seeks to shed light on how digital tools are transforming not just the ways we record data, but the very questions archaeologists ask of this information and how this will shape methodological and analytical trends in the next decade and beyond.
Assessment of galactose-1-phosphate uridyltransferase activity in cells and tissues
Authors: L. Brophy Megan , E. Murphy John , D. Bell Robert
Published: June 2021

Galactosemias are a family of autosomal recessive genetic disorders resulting from impaired enzymes of the Leloir pathway of galactose metabolism including galactokinase, galactose uridyltransferase, and UDP-galactose 4-epimerase that are critical for conversion of galactose into glucose-6-phosphate. To better understand pathophysiological mechanisms involved in galactosemia and develop novel therapies to address the unmet need in patients, it is important to develop reliable assays to measure the activity of the Leloir pathway enzymes. Here we describe in-depth methods for indirectly measuring Galacose-1-Phosphate Uridyltransferase activity in cell culture and animal tissues.
Catfish (Clarias sp.) as an animal protein source to improve serum albumin levels of hemodialysis patients
Authors: Widiany Fery Lusviana , Astuti Ari Tri
Published: June 2021

Background: Hemodialysis patients often experience hypoalbuminemia complications, which occur mainly due to decreased synthesis due to inflammation, lack of protein intake, the fluid status of patients, and losses from the dialysate. Another problem in hemodialysis is malnutrition, with a prevalence between 23–73% globally. Gastrointestinal disorders such as nausea, vomiting, and decreased appetite also often occur in hemodialysis. Therefore, hemodialysis patients need to get nutritional support, which can be given in the form of catfish abon, one of the local Indonesian food.Objective: To determine the effectiveness of the use of catfish as a source of animal protein to improve the albumin levels of hemodialysis patients.Materials and Methods: This was a quasi-experimental study with a pre-post test design. This study involved 34 hemodialysis patients as subjects, with inclusion criteria, were routinely two times a week, aged >18 years, willing to be the subject and follow the research procedures, have albumin levels ≥3.0 g/dL, and no catfish allergies. Patients with anasarca edema, experiencing complications of diabetes mellitus and malignancy were excluded. The dependent variable was albumin content, while the independent variable was catfish as an animal protein source. Data were analyzed univariate and bivariate by Fisher's Exact test.Results: Fisher's Exact test results on the effectiveness of using catfish as an animal protein source to improve albumin levels of hemodialysis patients showed p-value=0.048.Conclusion: The use of catfish as an effective animal protein source significantly affected on improving albumin levels in hemodialysis patients.

Authors: Damayanti Amilia Yuni , Darni Joyeti , Hafidzatunnisa Hafidzatunnisa
Published: June 2021

ABSTRAK Background: As much as 73.4% of children aged ≥ 5 years in Indonesia have breakfast with the low nutritional quality of food consumption, as evidenced by the prevalence of 95.5% of children's less consumption of vegetables and fruits. Breakfast habits affect fiber and micronutrient levels. Communication and nutritional information can increase accuracy in breakfast behavior from childhood. Effective and efficient media are needed. So far, the media for children has prioritized illustrations without paying attention to the cultivation of moral values.Objectives: This study aimed to determine the effect of Islamic comic media on improving healthy breakfast attitudes among students.Materials and Methods: The research design was a quasi-experimental type. Subjects were taken by a simple random sampling method. Ninety-six students were divided into three groups. Group A was given nutrition education using Islamic comic media about health breakfast (n = 32). Group B was given nutrition education using Islamic comic strip media about health (n = 32). Group C was a control group (n = 32). The study used two types of nutrition promotion media: comics and comic strips, which are stories about healthy eating in Islam. The time for nutrition education intervention through comics and comic strips is 2x ± 35 minutes. The pretest was ± 25 minutes with ± 10 minutes explaining the instructions for filling out the questionnaire. The posttest was ± 25 minutes with a discussion for ± 10 minutes—nutritional attitudes related to health breakfast by answering a validated questionnaire. We used the Lickert scale to categorized nutritional attitudes. Statistical test was done by Wilcoxon and Mann Whitney test.Results: The distribution of nutrition attitudes of respondents increased after the provision of Islamic comics, both comics and comic strips about breakfast. The nutritional attitudes increased significantly in the Islamic comic media group (p = 0.000) and the Islamic comic strip media group (p = 0.000), from 78.75 to 92.96 and 78.61 to 92.88, respectively.Conclusions: There was a relationship between counseling and Islamic comic media regarding healthy breakfast towards the nutritional attitude of elementary school-age students.
SMALL AREA ESTIMATION METHOD WITH EMPIRICAL BAYES BASED ON BETA BINOMIAL MODEL IN GENERATED DATA
Authors: Yanuar Ferra , Fajriyah Rahmatika , Devianto Dodi
Published: June 2021

Small Area Estimation is one of the methods that can be used to estimate parameters in an area that has a small population. This study aims to estimate the value of the binary data parameter using the direct estimation method and an indirect estimation method by using the Empirical Bayes approach. To illustrate the method, we consider three conditions: direct estimator, empirical Bayes (EB) with auxiliary variables, and empirical Bayes without auxiliary variables. The smaller value of Mean Square Error is used to determine the better method. The results showed that the indirect estimation methods (EB method) gave the parameter value that was not much different from the direct estimation value. Then, the MSE values of indirect estimation with an auxiliary variable are smaller than the direct estimation method.
Determination of suitable areas for organic production in Kelkit basin and mapping by geographical information systems
Authors: Karadağ Hakan
Published: June 2021

Kelkit Basin contains 17 districts within the boundaries of Tokat, Amasya, Gümüşhane, Giresun, and Sivas provinces. The Basin is located in the Middle Black Sea Region of Anatolia, at 40.9968 North, 30.8491 East, 36.0482 South, and 36.6943 West coordinates. The total area of the basin is 16.244,45 hectares. The altitude of the basin surrounded by high mountains ranged from 200 m (base of the valley) to 1200 m (high plain). The height of the mountains gradually increased from west to east until 2400 m. There is not any major industry establishment limiting the level of organic agriculture in the basin. The main livelihood of the people in the region is agriculture. Our study aimed to determine and mapping the suitable areas for organic agriculture in the basin. For this purpose, land surveys were conducted, point data were collected with GPS and the 1230-point value are calculated. On the calculation of point value, Land Use Capability, land pollution situation, erosion risk groups, and soil groups are used as criteria. In line with the regulation of organic farming practices, in the calculation the amount of pollution; intense agricultural activity, the impact of roads, settlement influence, water resources, the effects of soil pollution, and industrial-mining areas were taken into account. By using these calculated values, maps were created in the program ArcGIS (9.3) by analysis of IDW (Inverse Distance Weighted). According to the generated maps, the organic agricultural potential of the region was put forward.
Effect of pollinator cultivars on nutrient content in some Turkish hazelnut cultivars
Authors: Balik Huseyin Irfan
Published: June 2021

The main objective of this study was to assess the pollen effects on macro and micro nutrition elements on hazelnut cultivars (Corylus avellana L.). Tombul, Palaz, Çakıldak, Foşa and Allahverdi were used as main cultivars while Tombul, Palaz, Çakıldak, Foşa, Allahverdi, Sivri, Kalınkara and Yassı Badem were used as pollinator cultivars. In the study, it was investigated that the pollinator cultivars caused changes in some nutrition elements. The effects of the applications on nitrogen, phosphorus and potassium content were found to be statistically significant. It was determined that the nutrition element with the highest rate in the examined hazelnut cultivars is potassium. It has been observed that the amount of potassium is high in Tombul-pollinator treatments. The potassium content of Foşa and Çakıldak weres found to be higher than other cultivars. In Palaz and Yassı Badem- pollination treatments, it has been observed that the Ca content is generally lower than other treatments. Fe content was found to be significantly higher in Palaz-pollination treatments. The highest Mn and Zn content was obtained from Çakıldak. As a result, it has been revealed that pollinators may have an effect on nutrient content.

AGGREGATE LIQUIDITY CREATION OF ISLAMIC BANKS IN TURKEY
Authors: AKIN Ozlem , OZSOY S. Mehmet
Published: June 2021

This paper provides a detailed analysis of aggregate liquidity created by Islamic (participation) banks in Turkey. Using quarterly regulatory dataset for the period of 2010–2017 and applying Berger and Bouwman framework to measure liquidity creation, we document that the liquidity created by Turkish Islamic (participation) banks has tripled (in inflation adjusted terms) in our sample period. Furthermore, we find that Islamic banks have created liquidity both on and off their balance sheets. Finally, we observe that Turkish Islamic banks have been creating more liquidity with their liabilities than their assets. Despite the continuous upward trend in aggregate liquidity created by Turkish Islamic banks, their loan-to-asset and deposit-to-asset ratios have been declining in our sample period, which suggests that the observed trend has been driven by extensive margin (i.e., bank sizes growing in real terms) rather than the intensive margin (banks creating liquidity more effectively).
IS TRADE AGAINST OR IN FAVOR OF WOMEN? EMPIRICAL EVIDENCE FROM MANUFACTURING SECTOR IN TURKEY
Authors: GENÇ İLERİ Şerife , ULU Mehmet Fatih
Published: June 2021

This paper studies the effect of trade openness on relative wage earnings of female workers in Turkey’s
manufacturing sector. We compute the export intensity of a sector by dividing the export value to
production value as our measure of trade openness. Using Structure of Earnings Survey data for 2010 and
2014, we estimate the impact of export intensity on the gender wage gap. Our results indicate that a onepercentage
point increase in the export intensity of a sector leads to a 0.17 percent higher gender wage gap.
We further investigate the trade-gender wage gap link by grouping the sectors into four quartiles according
to their export intensities. Our estimations for each quartile reinforce our finding of a negative impact of
trade on the male-female wage inequality. Lastly, we analyze how the wage gap between men and women
change according to skill levels. In line with the previous findings in the literature, we estimate a higher
wage discrimination against high-skill women.
Improved oscillation criteria for even-order neutral differential equations
Authors: Chatzarakis George E. , Jadlovská Irena , Tunç Ercan
Published: June 2021

New sufficient conditions for the oscillation of all solutions to a class of even-order differential equations with bounded and unbounded neutral coefficients are established, which refine, significantly simplify and generalize those in [T. Li and Y. V. Rogovchenko, Oscillation criteria for even-order neutral differential equations, Appl. Math. Lett. 61 2016, 35–41]. Examples are provided to illustrate the results and suggestions for future research are included.

Adaptive model predictive stabilization of an electric cargo bike using a cargo load moment of inertia estimator
Authors: Pai Suvrath , Neuberger Benedikt , Buchholz Michael
Published: June 2021

This paper addresses the problem of stabilizing an electric cargo bike. For most control objectives, it suffices to consider a cargo bike as a two-wheeler. However, in addition to the challenges posed to the control of traditional two-wheelers, electric cargo bikes also have the issue of the cargo load, which can significantly influence the driving behaviour. Hence, detection and estimation of the mass, position and inertial properties of the cargo load become important. Here, a Kalman filter based algorithm which estimates these parameters online is presented. For the estimation, measurements of the force exerted by the load are recorded using force sensors installed under the load. Along with these, roll angle and roll acceleration are also measured. The estimated values are then used by an adaptive model predictive controller (MPC) to adjust the model-parameters and stabilize a cargo bike while following a set trajectory.
Effect of synthesis and activation methods on the character of CoMo/ultrastable Y-zeolite catalysts
Authors: Nugrahaningtyas Khoirina Dwi , Heraldy Eddy , Rachmadani  , Hidayat Yuniawan , Kartini Indriana
Published: June 2021

The properties of three types of CoMo/USY catalysts with different synthesized methods have been studied. The sequential and co-impregnation methods followed by activation using calcination and reduction process have been conducted. The properties of the catalysts were examined using Fourier-transform-infrared (FTIR) spectroscopy, X-ray diffraction (XRD) with refinement, and surface area analyzer (SAA). The FTIR spectrum study revealed the enhanced intensity of its Bronsted acid site, and the XRD diffractogram pattern verified the composition of pure metals, oxides, and alloys in the catalyst. The SAA demonstrated the mesoporous features of the catalyst. Scanning electron microscopy showed an irregular particle morphology. Additional analysis using the transmission electron microscopy indicated that the metal has successfully impregnated without damaging the USY structure.
Homemade bismuth plating by galvanic displacement from bismuth subsalicylate tablets: a chemistry experiment for distance learning
Authors: Aguilar-Charfen Jose Luis , Castro-Sayago Ines , Turnbull-Agraz Jimena , Ibanez Jorge G.
Published: June 2021

This paper presents a student-designed one-pot electroless deposition of Bi extracted from a Pepto Bismol® tablet by galvanic displacement of the Zn coating of a galvanized iron nail. This experiment relies on a readily accessible and reasonably safe method and materials and it has been used during the present COVID pandemic as a hands-on activity with higher education students (i.e., Junior and Senior Chemical Engineering students). Its simplicity should allow its use with High School students as well. The entire procedure can be completed in 30–45 min.
From the Newspaper Serial to the Novel (1853–1863): Mediation of the Periodical Press in the Foundation of Alberto Blest Gana’s Narrative Project
Authors: Pas Hernán
Published: June 2021

Scholarly studies on Alberto Blest Gana have generally disregarded the author’s production prior to his narrative cycle, begun with his novelLa aritmética en el amor[Arithmetic in Love] (1860), awarded first prize in a literary contest sponsored by the Universidad de Chile. Nonetheless, the canonical cycle of his first narrative period (which includes his famousMartín RivasandEl ideal de un calavera) shares with his earlier fiction the fact that the novels were originally published in the press. Indeed, with the exception of the award-winning novel andJuan de Aria – published in theAguinaldoof the newspaperEl Ferrocarril – all the author’s production from his first narrative period was published in periodical publications, decisive in consolidating his narrative project. This essay analyses the mediation of the periodical press (and its subgenres, such as thefolletín[newspaper serial] and theartículo de costumbres[a literary vignette of customs]) in the foundation of Blest Gana’s narrative scheme, contemplating the diversity of his production. The main features of his project were embodied, materially speaking, in the space of thefolletín. It was in this space, in short, where the author’s narrative managed to challenge an extended reading public, necessary for the constitution of a national literature.
Bounds on Shannon functions of lengths of contact closure tests for contact circuits
Authors: Popkov Kirill A.
Published: June 2021

We consider the problem of synthesis of irredundant two-pole contact circuits which implement n-place Boolean functions and allow short single fault detection or diagnostic tests of closures of at most k contacts. We prove that the Shannon function of the length of a fault detection test is equal to n for any n and k, and that the Shannon function of the length of a diagnostic test is majorized by n + k(n − 2) for n ⩾ 2.
Convex algebras of probability distributions induced by finite associative rings
Authors: Yashunsky Alexey D.
Published: June 2021

We consider the transformations of random variables over a finite associative ring by the addition and multiplication operations. For arbitrary finite rings, we construct families of distribution algebras, which are sets of distributions closed over sums and products of independent random variables.
