Детектирование субтерагерцевых колебаний на основе гетероструктуры антиферромагнетик/тяжелый металл
Authors: Козлова Е.Е. , Сафин А.Р.
Published: April 2022

We study a model of a detector of subterahertz electromagnetic waves based on an array of heterostructures containing an antiferromagnet and a heavy metal. We show that the operating frequency of the detector can be tuned by a constant magnetic field applied in the direction of the easy magnetization axis of the antiferromagnet. The dependence of the rectified voltage on the frequency of the external electromagnetic wave for different values ​​of the constant magnetic field is resonant in nature, and an increase in the constant magnetic field leads to an increase in the resonance peak. It is shown that the use of an array of antiferromagnets in the form of a comb structure makes it possible to increase the level of the rectified output voltage.
Frequency and Correlates of Online Consultations With Doctors or Therapists in Middle-Aged and Older Adults: Nationally Representative Cross-sectional Study (Preprint)
Authors: Hajek André , König Hans-Helmut
Published: April 2022

BACKGROUND

A few studies have identified the frequency and correlates of online consultations with doctors or therapists. However, there is a lack of studies using nationally representative data from middle-aged and older adults in Germany.

OBJECTIVE

This study aims to determine the frequency and correlates of online consultations with doctors or therapists in Germany.

METHODS

For this study, cross-sectional data were taken from the nationally representative German Ageing Survey (DEAS; n=3067 in the analytical sample; age range 46-98 years). As part of the DEAS, a short survey was conducted between June 8 and July 22, 2020, examining the everyday life and living conditions among these middle-aged and older individuals during the COVID-19 pandemic. The frequency of online consultations with doctors or therapists served as the dependent variable (daily, several times a week, once a week, 1-3 times a month, less often, and never). Multiple logistic regressions were performed.

RESULTS

In sum, 10.02% (381/3806) of individuals with access to the internet had online consultations with doctors or therapists. Multiple logistic regressions showed that the likelihood of using online consultations with doctors or therapists (compared with those never using such services) was positively associated with higher education (compared with medium education; odds ratio [OR] 1.31, 95% CI 1.01-1.70), living with a partner in the same household (compared with single; OR 1.53, 95% CI 1.05-2.22), poorer self-rated health (OR 1.42, 95% CI 1.16-1.74), increased loneliness (OR 1.45, 95% CI 1.10-1.90), and increased satisfaction with life (OR 1.30, 95% CI 1.03-1.64).

CONCLUSIONS

Study findings suggest that a non-negligible proportion of about 1 out of 10 individuals aged 46 years and over had online consultations with doctors or therapists. However, compared with other countries, this proportion remains small. Knowledge about the correlates of (non)use may assist in identifying corresponding individuals. In times of reshaping the health care system, these efforts in online consultations with doctors or therapists may contribute to addressing patient needs. Moreover, increased use of such services may reduce the risk of getting infected with SARS-CoV-2 by reducing social contact.

Authors: Michalski Stefan Carlo , Szpak Ancret , Ellison Caroline , Cornish Rowena , Loetscher Tobias
Published: April 2022

BACKGROUND

People with Down syndrome face various learning challenges. Introducing new and enjoyable experiences in learning settings may improve learning outcomes. Immersive and interactive technologies such as virtual reality can be used to deliver rich visual experiences in classrooms.

OBJECTIVE

The aim of this study was to investigate the feasibility and benefits of virtual reality exposure for people with Down syndrome in learning settings.

METHODS

To address this aim, we used a within-subjects design to assess the effect of a brief virtual reality drawing experience and conventional drawing experience on subsequent behavior in 16 participants.

RESULTS

Large positive effects were found for virtual reality drawing (t15=5.020, P<.001) and conventional drawing (t15=3.720, P=.002) in improving subsequent behavior in a learning setting. Irrespective of the intervention, the participant’s mood, attention, and overall behavior significantly improved. No significant differences were found between the interventions (t15=–0.648; P=.53).

CONCLUSIONS

This study’s results are encouraging for researchers and educators interested in using virtual reality for people with Down syndrome, as virtual reality was found to be highly feasible. Recommendations are made for researchers and educators interested in providing virtual reality experiences for people with Down syndrome.

Iako je Komisija za eliminaciju rasne diskriminacije (CERD), još 2006. godine izrazila „zabrinutost zbog odsustva oficijelnog priznavanja rusinske nacionalne manjine uprkos njenim posebnim etničkim karakteristikama”, Ukrajina do danas nije priznala Rusine kao nacionalnu manjinu. Za razliku od svih država sveta u kojima žive Rusini, samo Ukrajina se još uvek drži svog Plana mera za rešenje problema Rusina-Ukrajinaca iz 1996. godine kojim se, između ostalog, nalaže Nacionalnoj akademiji nauka Ukrajine i Ministarstvu obrazovanja Ukrajine (a otud i Ambasadi Ukrajine u Srbiji) da „realizuju školski sistem sa postepenim širokim razvijanjem etničkih, lingvističkih, kulturnih i političkih aspekata istorije Rusina-Ukrajinaca Zakarpatja kao nedeljivog, istorijskog dela ukrajinskog etnosa.” Rusinske organizacije (prvenstveno Matica Rusinska i KPD DOK) kontinuirano objašnjavaju nameru i političku manipulaciju Saveza Rusina Ukrajinaca Srbije (SRUS) i očekuju od svojih državnih vlasti da se sa stanovišta čuvara ustavnih rešenja, s pozivom na Povelju OUN i relevantne međunarodne konvencije javno distanciraju u odnosu na aktivnost Ukrajine i delovanje SRUS-a, koga podržava.

Published: April 2022

Članak tretira prelomne godine za raspad Varšavskog ugovora i sudbinu socijalizma u Istočnoj Evropi što je imalo odraza na situaciju u Jugoslaviji. Rad je utemeljen najviše na do sada neobjavljenim dokumentima diplomatskih predstavništava SFRJ u Varšavi, Pragu i Berlinu iz 1988-1989. godine. Korišćena je i opšta literatura za tematiku hladnog rata i posleratnu istoriju Evrope. Posle uvođenja „perestrojke“ u SSSR-u ubrzani su reformski procesi u Poljskoj koja je bila najneuralgičnija tačka Istoka. Posledično, kriza se prelivala u druge zemlje socijalističkog bloka centralne Evrope kao što su ČSSR i NDR. Rezultat je bio taj da je umesto proklamovanog reformisanog socijalizma nastupio neoliberalni kapitalizam prekopiran sa Zapada.
Working Paper PUEAA No.1. Green policies within the framework of the socio-ecological system and the Sustainable Development Goals: an approach from the cement industry
Authors:   Facultad de Contaduría y Administración, UNAM, Vera Martínez Paola Selene
Published: April 2022

Since the 1970s there has been a growing interest in international cooperation policies to fight against climate change and its effects on the planet, but these have not had the expected results. One of the main criticisms of these policies is that they have not addressed the issue of human development and the existing socioeconomic differences. This is why the UN 2030 Agenda has focused on the Sustainable Development Goals (SDG) that seek the protection of the environment, on a par with that of human societies. Since both are interdependent, they must be addressed and their problems solved in a sustainable way, taking into account all the socio-economic factors that may affect the results or actions to be taken regarding climate change, both at macro and micro levels in economic and social terms.
Working Paper PUEAA No. 2. Green Policy driven activities at Hiroshima University

Published: April 2022

The University of Hiroshima has decided to focus on how the organization of human societies and the problems generated by these, have impacted the environment, as well as the influence that these should have as factors in the so-called "green policies" in order to create sustainable development. It is through education, mainly in universities, that we seek to create not only awareness but also a research base on which to work and create support and working networks towards the labor and business sectors with an emphasis on environmental care. By creating an intersectional model, the necessary measures for environmental protection can be better understood and applied without neglecting human and economic development, which are equally important for the progress of societies. The activities presented by the University, and that seek to expand to Mexico, are a great opportunity to create such networks in the country and understand the development-environment interrelationship.

Published: April 2022

Despite their remoteness from each other, Japan and Mexico share a critical characteristic: the seismic hazard. In the past, both nations have been hit by great earthquakes that have caused serious human and material losses. Although the prediction of earthquakes is not yet possible, the development of early warning systems and their constant innovation is a priority, especially the studies of the horizontal-to-vertical spectral relationship of microseisms, which can help the study and understanding of earthquakes’ nature, as well as their impact on infrastructure. It is for mutual benefit to Japan and Mexico that cooperation between university institutions specialized in seismological studies increases to jointly create study and innovation mechanisms.

Due to its position between various tectonic plates, Japan is at constant risk of natural disasters such as volcanic eruptions, earthquakes, and tsunamis. The latter have a great and destructive impact since a large part of the Japanese population lives on coastal plains. The importance of having early warning systems has led Japanese scientists to give particular importance to the study of the seabed and its tectonic characteristics, in order to better understand its geological composition, and to be able to create better and faster early warning systems with new technologies for transmission and data collection.
Working Paper PUEAA No. 11. Profit Seeking Model and the Monetary Policy in Japan: cross-border asset holdings via Offshore Financial Centers
Authors:   Nanzan University, Yasuhara Tsuyoshi
Published: April 2022

Recently, the Junichiro Koizumi and Shinzo Abe administration has adopted labor reforms, and monetary authorities have updated unconventional monetary policies: quantitative easing of money supply and negative interest rate control. It can be identified that quantitative easing policy and negative interest rate policy have introduced and stimulated new styles of profit-seeking through stock market transactions, which only increases corporate and bank profits under a stagnant labor productivity growth rate. Under such a context, this paper analyzes the changing phase of the profit-seeking patterns of the financial and non-financial sector in Japan. The hypothesis is that the large-scale corporate sector has created a new profit-seeking paradigm and that this has been supported by the monetary control of the so-called "Abenomics".

FILTRATION PROBLEM WITH NONLINEAR FILTRATION AND CONCENTRATION FUNCTIONS
Authors: Safina Galina
Published: April 2022

ncient architectural buildings are of great value for all modern humanity. Over time, under the influence of vibrations, water and other man-made and natural factors, the foundations of such buildings are destroyed, the soil structure changes. Currently, one of the most popular methods of strengthening soils and strengthening foundations is the jet grouting technology. When the liquid grout passes through the porous rock, the suspended particles of the grout form a deposit. In this paper, we study a one-dimensional model of suspension deep bed filtration in a porous medium with different particle capture mechanisms. The considered filtration model consists of the balance equation for the masses of suspended and retained particles and the kinetic equation for deposit growth. In this case, the deposit growth rate is determined by the concentration function of suspended particles, which, in turn, depends on the properties of the suspension and the geometry of the porous medium. The solution to the problem is obtained for linear and non-linear concentration functions. An asymptotic solution of the problem is constructed for both types of functions near the concentration front of suspended and retained particles. It is shown that the asymptotic and numerical solutions are close over a long time interval.

The enactment of Law Number 4 of 2019 concerning Midwifery (Midwifery Law) provides its euphoria for the midwifery profession in Indonesia. The purpose of establishing the Midwifery Law is to improve the quality of midwives and midwifery services, provide protection and legal certainty to midwives and clients, and improve the health status of the community. Do the provisions in the Midwifery Law support the realization of these goals? This research tries to see whether the principle of clear objectives (beginsel van duidelijke doelstelling) as a material principle in the formation of the Midwifery Law has been manifested in the formulation of norms in the Midwifery Law, or other words whether the formulation of norms in the Midwifery Law supports the realization of the objectives of the formation of the Midwifery Law. This research specifically looks at the aspects of midwifery education as a starting point and a central point in improving the quality of midwives and midwifery services in Indonesia. This research is a qualitative study using the method of reviewing regulations and literature related to the regulation of midwifery education in Indonesia. As for normative legal research, it used a statutory approach. The results of the study indicate that the norms in the Midwifery Law, particularly related to midwifery education, are counterproductive with the aim of the formation of the Midwifery Law to improve the quality of midwives and midwifery services in Indonesia.

The infamous “master manipulators” – intracellular bacteria from the
genus Wolbachia – infect a broad range of phylogenetically diverse
hosts in terrestrial ecosystems. Wolbachia have important impacts on the
ecology and evolution of their hosts with documented effects including
induced parthenogenesis, male killing, feminization, and cytoplasmic
incompatibility. On the other hand, data on Wolbachia infection in
non-terrestrial invertebrates is scarce. Sampling bias and
methodological limitations are among the reasons we are unable to detect
these bacteria in aquatic organisms. Here we presented a metabarcoding
method to detect the co-occurrence of different Wolbachia strains in
new, to science, host species: water bears (Tardigrada), freshwater
arthropods, and mollusks. In addition, we describe a new Wolbachia
strain (supergroup V) and identify a very widespread supergroup A. This
supergroup could indicate transinfection and Wolbachia abilities to
switch hosts within new environmental conditions, and between hosts that
are ecologically connected. Future research should focus on ecological
and evolutionary relationships between a new host species and the
“master manipulator”.

Soybean oil is the most consumed oil worldwide due to its cheapness but
presented a weak thermo-resistance compared to most other oils used.
This study aims to improve the thermo-stability of soybean oil by
blending with crude oils. For this, physicochemical and antioxidant
parameters of each blended oil were assessed before and after thermal
treatment at 170°C for 10h/day for 5 days. The results of binary blended
oils indicated that soybean oil mixed with lentisk, sesame, and almond
oils (70:30%) manifested the best thermo-stability parameters. The
Simplex Lattice Mixture Design applied for these three selected oils
indicated that the combination of soybean oil at the proportion of 70%
with lentisk oil and sesame oil at proportions of 17.7% and 12.3%
respectively was selected as the best blending for maximizing soybean
oil properties. Fatty acids analysis by GC/FID technique showed that the
level of the degradation of linoleic acid (ω6) and linolenic acid (ω3)
after heat treatment was more important in soybean oil than in blended
oil. This study demonstrated that the thermo-resistance and nutritional
quality of soybean oil were improved by blending with sesame and lentisk
oils.

Assessment of the governance sustainability of agricultural enterprises in Bulgaria
Authors:   Institute of agricultural economics, Sarov Angel
Published: April 2022

Sustainability is explored in various areas - from sustainable development: through sustainable economic growth, to sustainable ecosystems. In this regard, research on sustainability in agriculture has always been relevant not only for academia but also for practitioners, politicians, consultants, environmentalists, and others. There are three main pillars in the scientific literature for sustainability assessment: economic, social, and environmental. This paper seeks to answer the question: Are these the main pillars for sustainability assessment? And: Can another (governance) pillar be included to help with this assessment? The task is to measure and assess the governance sustainability of a particularly sensitive sector of the economy, such as agriculture. A system of principles, criteria and indicators for assessing governance sustainability at the farm level is proposed. The proposed evaluation concept can be a useful tool for adjusting and improving agricultural policy at national, regional, and local levels, as well as its implementation by public administration bodies

Family farms are the main form of agriculture farming not only in Bulgaria but also in Western Europe as well as around the world. They are a distinct hereditary agricultural business, whose sustainable development in the agricultural sector is achieved through maintaining the optimal condition of its basic components. From a scientific point of view, this means achieving high and sustainable yield, which can be obtained by: applying integrated and biological plant protection, proper selection of plant materials, reducing the introduction of harmful emissions into the environment, as well as maintaining and improving the quality of food products of agricultural origin, and development of organic farming. The purpose of this research is to analyze the types and possible methods of plant protection carried out by family farms in Bulgaria in order to obtain higher yields and develop more successful and sustainable agriculture in the future. The methods used in this scientific paper are: methods of deduction, analysis, induction, comparison, synergy, the checklist method, and extrapolation.
The cooperative – a pioneer in the loyalty programs’ using
Authors:   New Bulgarian University, Boevsky Ivan
Published: April 2022

Customer-focused organizations, regardless of their type and size, use customer loyalty programs extremely intensively as a modern marketing and management tool. In the paper, I am looking for an answer to the question: Are customer loyalty programs so new and modern, or do their roots go deep into human business history? The comparison between the ideal-theoretical DNA elements of the customer loyalty program with the ideal-theoretical DNA elements of the cooperative, formulated when it was established in 1844. unequivocally shows that the DNA of the customer loyalty program is part of the DNA code of the cooperative. Therefore, customer loyalty programs have been deeply rooted and used by the cooperative for more than 150 years and for it they are neither a new phenomenon nor a modern phenomenon, much less a modern marketing and management tool.

Kven er du? Om å møta seg sjølv i det å skapa
Authors: Bolstad Kristin
Published: April 2022

In this essay Kristin Bolstad describes how her development as a composer has been strongly influenced by her meeting with Magnar Åm as teacher of composition in his course in Intuitive composition, improvisation and music philosophy at Volda University College. Bolstad identifies several important characteristics of Åm’s pedagogic approach. Firstly, that finding one’s creative expression is inextricably linked with questions of human identity. Through various exercises designed for the enablement of intuitive processes, students were challenged to seek “ever inwards” to deeper levels of awareness, using their increasing self-knowledge as a tool in creative work. In this way, rather than looking for inspiration outside oneself, Bolstad describes how she began to “open an inner door”, to “listen” and discover properties and skills within herself that otherwise seemed hidden or forgotten. However, there are risks involved in listening and acknowledging one’s own blockages and self-judgements. While Åm’s approach involved a constant quest inwards, driven by unrest, it also involved learning to accept and to rest in this state of fumbling and disquiet, and to value the state itself.
A further characteristic for Åm’s approach is the notion of exploring external parameters such as the properties of the performance location in the composing process, and allowing the room itself to be one of the participators – an approach to composing Bolstad has used several times.

This article aims to describe what happens in musical improvisation with a particular focus on time experience. A phenomenological perspective will lead the descriptions. Actions that occur in improvisation depend on grouped memory functions, that is, one experiences time as a now-point with a start and end. The term chunking is central and explains how grouping occurs at a level of detail on micro, meso, and macro level. The article refers to the tension between the analytical and the intuitive, focusing on jazz improvisation. Using personal reflections from jazz practice, the author links introspective perspectives to more philosophical perspectives, and points out that musical presence often depends on thorough preparations in advance, enabling a surplus to be present in the situation. Both the context and complexity of material determine strategic choices, and general and contextual information types are not separate but affect each other through interpersonal interaction and negotiation.
Flere ting på en gang? Pluralisme i lydlig erfaring og utøvelse
Authors: Barth Andreas , Fooladi Erik C.
Published: April 2022

Herein, we circle around a sound phenomenon that may appear trivial but that under closer investigation turns out to be both complex and manifold: The sound of water poured into a glass or mug. We use existing research from various disciplines as well as our own sound recordings, and thus explore both scientific and aesthetic aspects of the sound of hot and cold water, and the differences between the two. Drawing on the thinkers Bateson, Berlin, and Dewey, we discuss relations between «trivial issues» and «the large questions» (Bateson), whether a phenomenon can be more than one thing at the same time (Berlin), and human experiences in encounters with the phenomenon (Dewey). We discuss this against various forms of interdisciplinarity and collaboration across traditional epistemic boundaries and hierarchies. This way, we reflect upon how an everyday phenomenon can be a meeting place between the aesthetic, educational and scientific, both with regards to this specific phenomenon, and on a more general basis.
Om stillhet, raseri og rytme
Authors: Pedersen Torgeir Rebolledo
Published: April 2022

In this essay the poet Torgeir Rebolledo Pedersen explores the intersection of sound and silence in a text as a particular location for the creation of meaning. With reference to poems of Rolf Jacobsen and Robert Creely, Pedersen asserts the reciprocity of sound and silence as conditions for each other, and for the life-affirming musical component of rhythm. While one property of silence is that it can never be total, whether in a text or in the world at large, another is that it can hold and harbor fury. Silence can thus be ambiguous, as an expression of unreflective and automatic passivity, but also a force within creative verbal expressions of rage and resistance, for instance against the politics of a previous prime minister who went on to lead NATO. Like the African slaves of history, we might understand the power of sound and silence harnessed in rhythm, in the service of survival and the expression of resistance. Pedersen understands both rhythm and silence dialectically, proposing that a particular, perhaps world-changing imperative may be found at the point of their intersection in the words of poetic texts.

Authors: Wicaksono Wimbo Pambudi
Published: April 2022

Feedbacks have been seen as an effective way to help language learners acquire second language competence. This study aims to find out how the written corrective feedback (CF) has been used in the adult ESL classroom. In this study, the data were generated through the learners writing. Then the data were put into direct, coded and uncoded type of the written corrective feedback. In addition, those types of feedback were categorized into content and form category to find the scope of the written corrective feedback. As the result, the direct written corrective feedback was mostly used by the teachers. Interestingly, the teachers only used the uncoded written corrective feedback when it refers to the content of the writing. Besides, the dynamic corrective feedbacks that occur several times can be a proof that the teachers not only focus on the form the writing but also the content.Keywords: written corrective feedback, ESL

Nova Scotia Prediabetes Project: upstream screening and community intervention for prediabetes and undiagnosed type 2 diabetes
Authors: Talbot P. , Dunbar M.J.
Published: April 2022

Introduction

Identifying individuals in the prediabetic state may help delay/prevent disease progression to type 2 diabetes mellitus. We explored the feasibility of a household mailing approach for population-based screening of prediabetes and unidentified type 2 diabetes mellitus, developed standard protocol, and developed and implemented community-based lifestyle programs.

Methods

The 16-item Canadian Diabetes Risk Assessment Questionnaire (CANRISK) was mailed to every household in two rural Nova Scotia communities. In total 417 participants aged 40 to 74 years with no prior diagnosis of diabetes self-administered the CANRISK and completed a 2-hour oral glucose tolerance test (OGTT) at a local health care facility. Those with prediabetes were invited to participate in a Prediabetes Lifestyle Program.

Results

Glycemic status was identified as normal, prediabetes or diabetes for 84%, 13% and 3% of participants, respectively. Association between glycemic status and overall CANRISK risk score was statistically significant. Six CANRISK items were significantly associated with glycemic status: body mass index, waist circumference, history of hypertension and hyperglycemia, education and perceived health status. Participants and physicians gave positive feedback on the CANRISK screening process.

Conclusion

The CANRISK holds promise as a population-based screening tool.
