The research of the role of interhemispheric interaction in problem solving: some behavioral and physiological results
Authors: Luneva A.R. , Korovkin S.Y.
Published: July 2019

In this paper we describe the role of interhemispheric interaction in problem solving. We have some ex- perimental hypotheses as a result of analysis of various theoretical approaches of corpus callosum functions and role of interhemispheric interaction in creative problem solving. In our research we adhere to the theory of joint work of two hemispheres during creative problem solving and the complex theory of the corpus cal- losum function. In this study we used a method of parallel probe tasks (choice of two simple alternatives) that was performed at the same time with the main problem task (insight or routine). Interhemispheric interaction was complicated by contralateral probe tasks. It means, when subject solve insight or routine problem, probe task was presented in the left/right visual field and was performed by the left/right hand. We register brain activity (EEG) during the whole experiment. The results showed us the specificity of mechanism of insight solution compared to routine solution, and that the interhemispheric interaction plays a significant role in insight problem solving.

Published: July 2019

The article presents the results of a comprehensive psychological and psychophysiological study of the impact of tolerance on uncertainty on mental adaptation among officers of the Armed Forces of the Russian Federation. The instrumental and diagnostic complex consisted of activity-behavioral, personal, emotional-volitional, psychophysiological methods. The definition of the psychophysiological features of the response to stress and the assessment of the state of the autonomic nervous system was carried out using Biofeedback. Following methods were used during the research — statistical method of clustering by the k-means method, Kolmogorov-Smirnov criterion, nonparametric Mann-Whitney criterion U for independent samples, construction of classification trees with moderation of significant factors. Also the article contains the description of the psychological profiles of officers with high and low meanings of tolerance for uncertainty. During the research it was found that the level of tolerance to uncertainty has an influence on the level of the mental situation, depending on the conditions of service. So, the group of people with high meanings of tolerance for uncertainty will show mental stability and professional reliability in a situation of extreme profile. It is found that high tolerance to uncertainty in the conditions of service in peacetime is associated with severe symptoms of emotional burnout, and such personal features as impulsivity, incontinence, risk appetite, and self-dissatisfaction. And the group with a low level of tolerance to uncertainty under extreme conditions will have high professional reliability and mental stability in conditions of service in peacetime.
Subjective quality of life and psychological adaptation of individuals with low, normal and high level of escapism
Authors: Teslavskaia O.I. , Savchenko T.N.
Published: July 2019

The article presents the results of a study of Subjective quality of life and Psychological adaptation level among individuals with low, normal and high level of Escapism (N=329, 18-52 years old Russians from big cities). Four tests were applied including the new Escapism Scale. Individual with high level of Escapism have lower Subjective quality of life in several parameters — Stability in Country, Confidence in Future, Ecology, Social recognition, Interesting Job, Health and Active life, Internal Harmony and Inner Conflict absence, Privacy (as a Personal Space), Self-Confidence, (Subjective well-being Questionnaire,
T. Savchenko, G. Golovina). ‘Excessive’ escapists also demonstrate lower level of psychological adaptation including Self-acceptance, Loyalty, Internality, Emotional Comfort, Intention to dominate (SPA Questionnaire, C. Rogers, R. Diamond). Because of that, Escapism can be characterized mainly as a compensational mechanism which emerges due to the reduced level of an individual’s adaptation to his/her social environment. The consistence of theoretical layout and empirical data obtained confirm the validity of presented Escapism Scale and its applicability for further empirical research.

Urban Indians, Native Networks, and the Creation of Modern Regional Identity in the American Southwest
Authors: Cahill Cathleen D.
Published: July 2019

This article explores the careers and political activism of Native opera singers in the Southwest of the 1920s. I argue that a number of talented Native artists recognized that engaging their audiences directly in live performances provided opportunities for public education in addition to their economic benefits. Partnering with regional boosters, they built careers performing in multiple pageants and events sponsored by municipalities across the Southwest. Live performance with its direct access to audiences also facilitated their political agendas of publicizing Indigenous histories. Their careers highlight the mobility of Indigenous people, demonstrating how they helped create modern urban spaces across the American Southwest.
Native Narratives, Mystery Writing, and the Osage Oil Murders: Examining Mean Spirit and The Osage Rose
Authors: Stoecklein Mary
Published: July 2019

Through analysis of two debut novels, Linda Hogan's Pulitzer-Prize-nominated murdermystery Mean Spirit 1990 and Tom Holm's private eye detective story The Osage Rose 2008, this article considers what Native-authored mystery fiction has to offer in terms of self-representation of Indigenous history and culture. Paying particular attention to detective fiction genre elements—such as the novels' openings, the detectives, the forms of detection, and the resolution—shows how Hogan and Holm employ the mystery genre to present Native narratives about the Osage oil murders, and, given their ability to reach wide audiences, how such narratives ultimately provide broader understandings of Indigenous history and culture.

Published: July 2019

The metals such as Fe, Cu, Zn and Mn are the essential elements that have an important role in the human immune system. The aim of this research was to determine the concentration of nutritive values of macroelements (N, P, and K) and microelements (Fe and Zn) in a mushroom substrate and in a champignon mushroom fruiting body. A trial was conducted in the mushroom production company Romanjek LLC in Slavonski Brod, Croatia. It was conducted in four vegetation cycles on two different substrates, the one originating from Eastern Europe and the other originating from Northern Europe. At the end of the trial, the basic chemical properties of substrates and mushrooms were recorded. A comparison of investigated substrate measurements demonstrates that the highest content of elements N, P, and K was determined in the substrate 2 originating from Northern Europe, while the concentration of microelements Fe and Zn was higher in substrate 1, originating, from Eastern Europe. There was a statistically significant difference in a macroelement content in the mushrooms grown on the substrates of different origin, as well as in the transfer of Zn and Fe from a substrate to mushrooms. There was a higher accumulation of the transferred Zn in comparison to Fe in the mushrooms regardless of the origin of the substrate.

Authors: Vranić Marina , Petek Marko , Bošnjak Krešimir , Lazarević Boris , Carović Stanko Klaudija
Published: July 2019

In this study, near-infrared spectroscopy (NIRS) was used to predict the contents of essential macro- and microelements in common bean (Phaseolus vulgaris L.) accessions of most widespread Croatian landraces. Total of 175 samples were used for the model development by modified partial least square (MPLS), principal component regression (PCR) and partial least square (PLS) techniques. Based on the coefﬁcients of determination (R2), standard error of calibration (SEC) and error of prediction (SEP) the models developed were (i) nearly applicable for nitrogen (N) (0.89, 0.12 and 0.45 respectively), (ii) poor for iron (Fe), cinc (Zn), potassium oxide (K2O) and potassium (K), (iii) usable for phosphorus pentoxide (P2O5), phosphorus (P), phytic acid (PA) and manganese (Mn). The MPLS regression statistics suggested the most accurate models developed comparing with PLS and PCR. It was concluded that a wider set of common bean samples needs to be used for macro- and microelements prediction by NIRS.
Social network analysis in Geosciences: scientific collaboration between periglacial scholars in the Iberian Peninsula
Authors: García-Hernández C. , Ruiz-Fernández J. , Serrano-Cañadas E.
Published: July 2019

This research examines the collaboration relationships between those authors affiliated to Iberian institutions and involved in periglacial studies between 2000 and 2017. The data has been extracted from the Google Scholar database and processed using Social Network Analysis (SNA) techniques. A total of 230 scientific publications have been selected, involving 198 researchers of which 113 belong to Spanish institutions, 38 to Portuguese institutions and 47 to foreign institutions. The work carried out by the Iberian community (assembled through national groups linked to the International Permafrost Association) has considerably improved its possibilities of dissemination and citation in this period: There has been an increase in the number of publications per year, in the number of authors per publication, and in the number of publications with international collaboration. Nowadays there is a group of very productive and well-connected authors, who play an important role as intermediaries, and future prospects are good. However, 50% of the authors have a low capacity for interaction, and there is a low presence of women in the network: These imbalances should constitute the main challenges to be faced by the Iberian community in the next decade. Beyond the Iberian community of periglacial scholars, this study provides an example of methodology to be applied in other co-authorship networks in subdisciplines of the Earth Sciences, and its results are discussed in this sense. The results of this research offer valuable information for the management of scientific collaboration programs, the selection of representatives and to weigh the possibilities and needs of the Iberian network. But, especially, it presents a socioscientific framework of reference for early career scientists and makes them aware of the need to integrate themselves into a booming scientific community.

University spaces: Creating cité and place
Authors: Temple Paul
Published: July 2019

This article examines a number of conceptualizations of interactions between people and physical space, and relates them to university settings to make a link with findings on institutional effectiveness. It argues that the idea of the common-pool resource, where certain physical or
social conditions are exploited collectively, is a helpful way of understanding how certain university spaces may be used productively. The opposite situation, the creation of a university 'non-place', must be guarded against. Planners and institutional managements can support the creation
of high-performing spaces managed in common, while allowing students and others to build their own community structures.

Authors: Altiparmak Ayse , Kuruoglu Gulmira
Published: July 2019

This research aims to analyze the influence of educational background on Turkish native speakers’ production rates of speech disfluencies. 56 native speakers of Turkish between ages 33-50 years and over 50-year-olds took part in the study. Each group was divided into two sub-groups according to the educational background of the participants. Prepared and unprepared speech samples of each participant were gathered via face-to-face interviews that were recorded and transcribed. As a result, participants with higher education levels produced more filled gaps than elementary/middle school graduates. In the prepared speech, over 50-year-old male elementary/middle school graduates produced more hesitations than male professors, and 33-50-year-old male elementary/middle school graduates produced more slips of the tongue than males with higher education. In unprepared speech situation, 33-50-year-old male elementary/middle school graduates produced more false starts than bachelor’s/master’s-doctoral degree holder males; however, over 50-year-old female professors produced more false starts than elementary/middle school graduate females.

Corrupción en la renta de tabaco del virreinato de Nueva Granada: El delito de malversación en la administración principal de Santafé (1778-1810)
Authors: Torres Güiza Johan Sebastián
Published: July 2019

El artículo se propone estudiar el fenómeno de la corrupción en la renta de tabaco del Nuevo Reino de Granada a finales del siglo XVIII a partir de los expedientes que los jueces subdelegados de rentas alzaron en contra de algunos estanqueros de la administración principal de Santafé por el delito de malversación y los alcances en sus cuentas. Con documentación cualitativa y cuantitativa del Archivo General de la Nación (Colombia), se detalla: el uso de los registros de «deudas a favor» o «debidos cobrar» como fuente histórica para el estudio de la corrupción y su posible cuantificación, y los mecanismos que utilizó la renta para castigar el delito de malversación y resarcir a la Real Hacienda. En definitiva, el artículo contribuye a explicar cómo la ausencia de un salario fijo en los administradores particulares de la renta de tabaco fue un factor que los motivó a participar en prácticas corruptas que fueron entendidas y juzgadas por el delito de malversación.

We develop a new Keynesian model featuring a dual-pillar monetary policy. We employ this framework to analyze the effects of coordinating macro-prudential rule and monetary policy in China using different tools. The simulation results show that: (1) adopting macro-prudential rule and monetary policy simultaneously can achieve a more stable economic environment than using monetary policy alone; (2) a price-based monetary policy is more effective in stabilizing economic fluctuations than a quantity-based monetary policy when considering the macro-prudential policy; (3) the combination of quantity-based monetary policy and macro-prudential rule can stabilize housing prices and credit growth better than the price-based tools. The study shows that when house prices rise rapidly owing to external shocks, adopting the quantity-based policy instruments and macro-prudential policy is a wise choice. When the financial condition is stable, the combination of price-based instruments and macro-prudential rule is better.

A quantum circuit implementation of Powell’s conjugate direction method (“Powell’s method”) is proposed based on quantum basic transformations in this study. Powell’s method intends to find the minimum of a function, including a sequence of parameters, by changing one parameter at a time. The quantum circuits that implement Powell’s method are logically built by combining quantum computing units and basic quantum gates. The main contributions of this study are the quantum realization of a quadratic equation, the proposal of a quantum one-dimensional search algorithm, the quantum implementation of updating the searching direction array (SDA), and the quantum judgment of stopping the Powell’s iteration. A simulation demonstrates the execution of Powell’s method, and future applications, such as data fitting and image registration, are discussed.

Traditional optical music recognition (OMR) is an important technology that automatically recognizes scanned paper music sheets. In this study, traditional OMR is combined with robotics, and a real-time OMR system for a dulcimer musical robot is proposed. This system gives the musical robot a stronger ability to perceive and understand music. The proposed OMR system can read music scores, and the recognized information is converted into a standard electronic music file for the dulcimer musical robot, thus achieving real-time performance. During the recognition steps, we treat note groups and isolated notes separately. Specially structured note groups are identified by primitive decomposition and structural analysis. The note groups are decomposed into three fundamental elements: note stem, note head, and note beams. Isolated music symbols are recognized based on shape model descriptors. We conduct tests on real pictures taken live by a camera. The tests show that the proposed method has a higher recognition rate.

Introduction

Preeclampsia, also called pregnancy-induced hypertension is a pregnancy-specific hypertensive disorder usually occurs after 20 weeks of gestation and affects both the mother and the fetus. preeclampsia is one of the driving causes of maternal and perinatal horribleness and mortality.

Objective

To assess the prevalence of preeclampsia and associated factors among women attending antenatal care service at Felge Hiwot Referral Hospital, Bahir Dar, Ethiopia, 2017.

Methods

Institution based cross-sectional study was conducted from March 1st up to 30th 2017. Study participants was recruited by using systematic random sampling technique. A pre-tested questionnaire was used for data collection. The data were checked for its completeness and consistency each day and the collected data was coded and entered into Epi Data version 3.1 and analyzed by using Statistical package for social science version 23. The logistic regression assumption was checked and fitted at P >0.05.

Result

The prevalence of preeclampsia was found to be 13.0% (95%CI: 8.3,17.6). Factors that had a statistically significant association with preeclampsia were women having a family history of hypertension [AOR=4.61(1.06, 20.07)], Gestational diabetes mellitus [AOR=11.41(1.40, 92.83)], using traditional medicine during pregnancy [AOR= 26.29(3.68, 187.84)].

Conclusion

the result indicated that the prevalence of preeclampsia in this hospital was higher than similar studies conducted in Ethiopia. Preventable and risk factors Having a family history of Diabetes Mellitus, Gestational Diabetes Miletus and taking traditional medicines during pregnancy were statistically associated with preeclampsia.
