Boundary Extension Effect Remembering Different Content Pictures
Authors: Radzevičienė Aldona , Jankūnaitė Jurgita
Published: June 2020

The goal of this study was to investigate in which cases boundary extension occurs when repainting visual images with different content from your memory. The method that was used in this study is based on a meta-analysis conducted by Hubbard et al. (2010). The method consists of 12 stimuli (dimensions 10x15 cm), which show a photographic image or sketch of a painting. Presented stimuli contain images with different content – finished object, object with its corners removed, emotionally neutral, positive and negative object, moving object; 120 respondents participated in the study, their age ranged from 14 to 45 years old (average age – 25,6).

The first hypothesis, stating that boundary extension is more frequent with images of objects with removed corners than those of finished objects repainted from memory, was confirmed. The second hypothesis, stating that boundary extension is more frequent with images of emotionally neutral objects than those of emotionally positive or intense objects repainted from memory, was confirmed. The third hypothesis, stating that boundary extension while repainting images that contain containing moving objects, form memory, unfolds from the expected direction of object movement – the left side, was not confirmed. It was found that boundary extension unfolded at the top of a painting (bird) and at the bottom of a painting (vehicle). The fourth hypothesis was partly confirmed – that boundary extension while repainting images from memory with different content stimuli is more likely to happen among teenagers (years 14–19). The central tendency is more likely among younger adults (20–30), and boundary restriction – among older adults (31–45). The fifth hypothesis was confirmed. As expected, boundary extension when repainting images of different content from memory more often occurrs with women than men. The sixth hypothesis, stating that boundary extensions are more often when repainting images from memory that were painted and are not photographical images, was not confirmed.

Hijab is identified with loins and still a discussion of ambiguity. Because the hijab from time to time has a narrowing of meaning. The issue was increasingly margined and raised to the international world after the French Government planned, and had even established restrictions on the use of religious symbols in French schools. One of them is the use of hijab which is said to be symbol of Islam. This article will discuss the hijab, including the views of middle-classical interpretations of scholars such as Ibn Taymiyah and contemporary interpretations of scholars such as M. Quraish Shihab. Here some views on the headscarves according to previous scholars seem too strict, with contemporary scholars being better known for their concessions in responding to contemporary problems. After that will be seen its relevance to the present.
Menjawab Keraguan Maurice Bucaille tentang Kesesuaian Hadis dan Sains
Authors: Fudhail Ahmad
Published: June 2020

This article attempts to criticizes the thoughts of Maurice Bucaille, an Orientalist from France who doubts the authenticity of the hadits contained in the book Ṣaḥīḥ al-Bukhārī, especially those relating to medicine. As the primary sources that author uses, the Book of La Bible, Le Coran, et La Science which has been translated into Indonesian by M. Rasyidi with the title Bibles, Quran, and Modern Science. This research seeks to examine and examine the thinking of Maurice Bucaille and then analyze the traditions that are doubtful of their authenticity with a medical science approach. The hadits that are authenticated by Maurice Bucaille -ḥadīth about the development of human embryos, hadits about flies, hadits about the usefulness of dates, and hadits about fever- are authentic hadits seen from a medical perspective.  In other words, the hadits is in accordance with modern science. This proves that the criticism shown by Maurice Bucaille is incorrect.

Published: June 2020

Background and Study Aim. Regular and reasonable physical activity seems to be one of the most recommended health-promoting human behaviours. The aim of the work was to determine the relationship between the declared and actual level of students' physical activity. Material and Methods. 118 students from the faculty of physical education aged 22.62±1.93 years participated in the study (61 men aged 23.12±1.78 years and 57 women aged 22.08±1.39 years). To determine the level of physical activity, the International Physical Activity Questionnaire (IPAQ) and the three-axis ActiGraph GT3X accelerometer were used in order to record physical activity parameters and the amount of energy expenditure. Results. The largest absolute difference without gender division was found in the average duration of physical activity in the medium intensity zone (16.83%). Differences in the level of weekly level of physical activity were noted in the whole group (13.79%; p<0.01) as well as in the group of women (relative difference 18.07%, p<0.01) and in the group of men (9.74%, p<0.01). A high correlation was observed between weekly energy expenditure calculated on the basis of declared values and the actual energy expenditure (r=0.94; p<0.05). Conclusions. Research carried out as part of the study showed that students declare a higher level of physical activity compared to the actual performed activity. On this basis, it can be concluded that there is a risk of error in assessing the volume of physical activity in a survey. The study showed significant gender diversity in the frequency and duration of physical activity undertaken by the respondents.
LGBT, Muslim, and Heterosexism: The Experiences of Muslim Gay in Indonesia
Authors: Khoir Anan Bahrul
Published: June 2020

Muslim gay and bisexual men have been facing various challenges when living in a homophobic and heterosexist society in Indonesia. However, the study of strategies they utilised to manage those homophobic attitudes, such as discrimination, prejudice, and stigma, of their sexual minority status is limited. Therefore, drawing on minority stress theory, this study explores the life experiences of Muslim gay or bisexual men in Indonesia, by focusing on the problems they faced and the strategies they used to address those issues. All participants aged between 20 and 27 years old, have self-identified as gay or bisexual men, Muslims or ex-Muslims, and have been living in Indonesia. The primary data collection was a semi-structured qualitative interview. The data were recorded and transcribed verbatim according to the research questions from a snowball sample of seven participants. The data were then analysed using thematic analysis. The study revealed that all the participants experienced sexual and religious related problems because of living in a homophobic society. These obstacles came in many forms, such as rejection, feelings of isolation and loneliness, and concerns. However, they employed strategies to solve problems, such as self-acceptance, self-control, positive reinterpretation, seeking social support, concealing, conversion, and migration. This study recommends those who support sexual minorities to help and support them in various ways, such as providing psychological services and counsellings.

Published: June 2020

The paper considers the problems of developing recommendations in the area of fiscal and trade policies to counter economic sanctions at the level of both individual countries subject to such sanctions and at the level of economic union including such countries. Research study has been carried out based on the developed dynamic multi-sectoral and multi-country computable general equilibrium model, which describes the functioning of the economies of nine regions of the planet, including five countries of the Eurasian Economic Union (EAEU). The initial data of the model contain built sets of consistent social account matrices (SAMs) for the historical and forecast periods based on data from the Global Trade Analysis Project (GTAP) database, national input-output tables, international trade and IMF data (including forecast) for the main macroeconomic regions indicators. Results of the impact on macroeconomic and sectoral indicators of the EAEU countries and other regions of a hypothetical scenario providing the imposition of additional economic sanctions since 2019 against Russia from some regions were obtained. An approach to solving problems to counter the sanctions policy based on the parametric control theory by setting and solving a number of dynamic optimization problems to determine optimal values of the corresponding fiscal and trade policy instruments at the level of individual EAEU countries and the EAEU as a whole was proposed.

The results of the model-based calculations were tested for the possibility of practical application using three approaches, including evaluation mappings’ stability of the exogenous parameters’ values of a calibrated model to the values of its endogenous variables. The results demonstrate greater efficiency for each EAEU country using a coordinated economic policy to counter sanctions, compared with the implementation of such policy separately at the level of each country.

Published: June 2020

This study examined the effect of stocking density on growth and survival of tilapia cultured in biofloc technology system. Three different stocking densities cultured in biofloc technology were 6 fish/m3, 8 fish/m3 and 10 fish/m3 for 86 days in triplicate for each treatment. The stocking density of the control lot was 3 fish/m3 cultured without biofloc technology. Initial stocking weight ranged from 2–3 g/fish. The water quality parameters were monitored and regulated in the suitable ranges for biofloc technology and for the growth and development of tilapia. The results showed that specific growth rate of fish cultured at a density of 6 fish/m3 was higher than that in the treatments of 8 fish/m3 and 10 fish/m3 with the average values of 5.72%; 5.62% and 5.43%, respectively, and the specific growth rate of fish in the control treatment was 5.71%. Daily growth rate of fish cultured at a density of 6 fish/m3 was higher than that cultured at densities of 8 fish/m3 and 10 fish/m3 with average values of 3.19 g/day, 2.98 g/day, and 2.55 g/day, respectively; and the daily growth rate of the control treatment was 3.27 g/day. Survival rate of tilapia cultured at densities of 6 fish/m3 and 8 fish/m3 was 100%, whereas survival rate of tilapia cultured at a density of 10 fish/m3 was 95.75%, and it was 88.9% for the control lot. The research results provide a scientific basis to propose tilapia culture technique in biofloc technology in brackish water, with the density of 6–8 fish/m3.

The social economy in Poland – a contribution to the criticism of innovativeness of national solutions
Authors: Goleński Wojciech
Published: June 2020

Since the outset of the 21st century, social innovations have become a popular concept in the description of solutions applied in the social policy of highly developed countries, different from those typical for traditional welfare regimes. In the expert discourse, the concept of innovation often has been associated with new forms of social economy. This article aims to present the inadequacy of the application of the concept of social innovation to the solutions that, in the light of the adopted definition, are no longer innovative. The paper develops an analysis of the up-to-date literature and available data on selected indicators relating to the social economy sector. As a result, current solutions were critically analysed and several questions, relevant from the perspective of future criticism of the innovativeness of country level solutions in this area, have been posed
Sharing economy and sustainable development in the opinion of the inhabitants of selected Polish cities
Authors: Banaszek Marcin
Published: June 2020

The economy of sharing is a new economic and social model, which main goal is to move from ownership to access. It consists of sharing underutilised resources or services – whether for a fee or free of charge. The paper explains the model of sharing economy in the context of modern urban problems. The aim of this article is to present the economy of sharing as a model that potentially contributes to sustainable development of modern cities. The quantitative study employs the diagnostic survey method. Using a survey questionnaire, we study the awareness of city residents about this new economic model, its perceived potential and trust residents put in the sharing economy solutions. The results suggest that the sharing economy is at least potentially a manifestation of sustainable development. Findings evaluate to what extent the sharing economy can contribute to solving problems of modern cities. The use of tools of sharing economy contributes to building social responsibility and shaping behaviours consistent with the idea of sustainable development

One of the most responsible stages of the competitive analysis of the market of services is strategic segmentation of competitors in which course strategic groups of competitors come to light.
In article the key barriers causing features of strategic grouping of competitors of sphere of sanatorium services of Krasnodar territory taking into account specificity of a segment of consumers, having problems with health («a medical segment») are allocated. Among the most significant barriers there was a departmental accessory, the organisation of the children's rest, used medical technologies (iatrotechnics, technology, shots), звездность, medical specialisation. On the basis of the revealed barriers ten strategic groups of competitors in the market of sanatorium services of Krasnodar territory, leaning against various sources of competitive advantages and key factors of success in competitive struggle, within the limits of a medical segment are isolated.
Prominent features have strategic groups of children's sanatoria. Here as a defining barrier the barrier of strategic grouping «the organisation of children's rest» has acted.
The special competitive status official bodies which managements owing to specificity are constrained enough in use of marketing toolkit, and also in manoeuvrability and flexibility of undertaken actions also have. It is allocated three strategic groups of competitors with participants – official bodies.
The basic players of the market of sanatorium services of Krasnodar territory – the departmental and independent sanatorium organisations, are united in four strategic groups of competitors.
Results of segmentation of competitors will allow the sanatorium organisations to define the strategic group on the basis of the revealed barriers of strategic grouping and can be used at formation of the competitive advantages allowing confidently to conduct competitive struggle among similar under strategic characteristics of the organisations. Segmentation of competitors also helps with more well-founded choice of competitive strategy.

Published: June 2020

ABSTRACT Background: Vascular cerebral infarction (or stroke) is recognized as the third leading cause of death worldwide, and acute arterial occlusion comprises the main mechanism underlying ischemic stroke. Cerebrovascular diseases are treated by intracranial endovascular interventions employing minimally invasive intravascular techniques, such as neuroimaging. Conducting practical training in this area is a necessary task since patient safety is a considerably significant factor. There has been a steady increase in scientific research focused on validating endovascular simulation as a tool for training interventionists in endovascular procedures. Current literature confirms the idea that there is a beneficial role of simulation in endovascular training and skill acquisition and technique improvement. Objective: To develop an endovascular technique simulator for learning Neuroradiology. Methods: The methodology consisted of developing a simulator using 3D printing technology. Results: A literature search was carried out, commencing in August 2017, through consultation of the Medical Literature Analysis and Retrieval System Online (MEDLINE) and Latin American and Caribbean Health Sciences Literature (LILACS) databases, using the PubMed and BIREME websites, respectively. Meetings were held between the neuroradiologist specialist and programmers to develop the simulator, which was carried out in three phases: design of the arterial system, design of the prototype of the arterial system in computer graphics, and confection of the arterial system simulator in 3D. Conclusion: The simulator is ready for testing by residents and can enable the student to learn through simulations that reproduce, as realistically as possible, the situation to be subsequently experienced using a concrete tool.

ABSTRACT The cowpea bean presents low productivity in the Pará state, Brazil, due to low soil fertility and climatic adversity, mainly water deficiency. The aim of this study was to evaluate the yield gap of cowpea bean in northeast of Para state in response to water deficit during its reproductive phase. The experiment was carried out in Castanhal, PA, Brazil, during 2015 and 2016. A randomized block design with six repetitions and four treatments was used; where T1 consisted of 100% replacement of the crop evapotranspiration (ETc), T2 to 50%, T3 to 25% and T4 without irrigation, in the reproductive phase. The yield was determined at R9 stage. The simulations with the SARRAZON model were carried out with different sowing dates. The total deficiencies in the reproductive phase were spatialized considering the 30 locations in order to assess the temporal and spatial seasonality of water availability and the sowing period in the study region. The cowpea bean was sensitive to soil water availability with considerable reductions in productivity due to the increase in water deficit compared to the treatment T1 (100% ETc). When water deficits reached more than 47 mm, there were yield gaps over 20%. According to the spatial variability of simulated water deficiency, the sowing of cowpea bean in regions located above 2° latitude may extend until June 20 without showing high yield gaps.

ABSTRACT Spatial variability analysis of meteorological elements and precise identification of possible causes of thermal stress in poultry housing help producers in the decision making process. The objective of this study was to evaluate the internal environment of poultry houses in the downtime (sanitary void) and in the production phase, to characterize spatial thermal variability and to identify critical control points. The study was carried out in the Alluvial Valley of the Mimoso River, municipality of Pesqueira, PE, Brazil. The data of air temperature, wind speed and illuminance were recorded in November (spring season), at 155 points within each poultry facility (10 x 90 m), spaced in a 3.0 x 2.5 m grid and subjected to descriptive statistical analysis and geostatistics. There was a strong spatial dependence for the variables air temperature, wind speed and illuminance. The ranges obtained for the air temperature in the facilities were from 48.22 to 114.52 m, while for the wind speed and illuminance were less than 10 m, thus revealing the need for greater homogeneity of the studied variables and meeting of the thermal requirement of the poultry.

Published: June 2020

ABSTRACT During the working day, agricultural machinery operators are often exposed to physical risks, such as vibration, which can compromise their health and performance. Micro tractors emit high levels of vibration, which mainly affect their hands and arms. Thus, this study aims at evaluating the efficiency of different glove models in reducing vibration transmitted by the micro tractor/rotary tiller assembly according to the operating velocity and the rotation of the rotary tiller rotor. A completely randomized block design was used in a 4 x 2 x 2 factorial arrangement with five replicates. The study analyzed three glove models (G1 and G2 anti-vibration models, and anti-impact model G3) and a control treatment under the same operating conditions, but without the use of protective equipment. The study was conducted at two operating velocities (V1 = 0.98 km h-1 and V2 = 1.6 km h-1) and two rotations of the rotary tiller rotor (R1 = 265 rpm and R2 = 520 rpm). None of the evaluated glove models reached the attenuation capacity required by the Occupational Hygiene Standard (Norma de Higiene Ocupacional - NHO 10) and, under some operating conditions, they raised the incident vibration levels, exceeding the values obtained when the work was performed without a protective equipment. Although the anti-impact model G3 and the anti-vibration model G2 did not reduce the transmitted vibration to the levels considered acceptable by NHO 10, the anti-impact G3 and anti-vibration G2 models showed better performance in the work performed at a velocity of 0.98 km h-1 and a rotation of 520 rpm of the rotary tiller rotor.

Parcerias, consórcios, pactos, dentre outros formatos identificáveis em diversas escalas territoriais, apresentam estrutura hibridizada reticular, agenciadas por organizações públicas e privadas, em diversas formas de associação. Credita-se às organizações associativas um protagonismo decisivo na ativação de redes e redes de redes, formatos interorganizacionais aos quais se atribui o poder de gerir o desenvolvimento territorial, ora mais orientados à competição, ora mais orientados às ações solidárias. Na intenção de melhor compreender a gênese e a textura das interorganizações voltadas ao desenvolvimento territorial, foram estudadas 180 organizações associativas em Salvador, Bahia, realizando uma pesquisa de tipo survey transeccional. Conclui-se com a caracterização destas organizações e com a discussão de seu papel nas conexões interorganizacionais integrantes de estratégias de desenvolvimento sócio-territorial, destacando-se ambigüidades, contradições e possibilidades.

Background: Sacubitril/valsartan has proven its efficacy to reduce cardiovascular mortality, all-cause mortality and sudden death in heart failure with reduced ejection fraction (HFrEF). Thus, it becomes important to evaluate the safety profile of the medication in clinical practice.

Objectives: This study aimed to assess safety outcomes on the use of sacubitril/valsartan in patients with HFrEF attended in a Brazilian specialized service.

Methods: Prospective observational study that included patients with HFrEF from a specialized ambulatory service, in functional class II-IV, initiated on sacubitril/valsartan as per clinical indication, with a four-month follow-up. Primary outcomes were the occurrence of symptomatic arterial hypotension, hyperkalemia and reduction of renal function. Serum potassium values, blood pressure and creatinine clearance were analyzed at inclusion and at the end of follow-up. A 5% significance level was considered for comparisons.

Results: Twenty-six patients were analyzed, 57.7% male, mean age 57.8 ± 10 years, average left ventricle ejection fraction 29.9 ± 7.7%. Symptomatic hypotension occurred in 53.8%, hyperkalemia in 19.2% and reduction of renal function in 6.7%. There was significant difference from initial to final systolic (122 ± 24mmHg versus 109 ± 15mmHg; p=0.024) and diastolic (76 ± 18mmHg versus 66 ± 12mmHg; p=0.022) blood pressure, but no difference in serum potassium (4.8 ± 0.4mEq/L versus 5.0 ± 0.3mEq/L; p=0.07) and creatinine clearance (65 ± 23mL/min/1.73m² versus 66 ± 29mL/min/1.73m²; p=0.89).

Conclusions: Symptomatic hypotension was the most frequent side-effect of sacubitril/valsartan. Reduction of blood pressure was observed at the end of follow-up, but no reduction of renal function or significant increase of serum potassium.
Deep Spiking Delayed Feedback Reservoirs and Its Application in Spectrum Sensing of MIMO-OFDM Dynamic Spectrum Sharing

Published: June 2020

In this paper, we introduce a deep spiking delayed feedback reservoir (DFR) model to combine DFR with spiking neuros: DFRs are a new type of recurrent neural networks (RNNs) that are able to capture the temporal correlations in time series while spiking neurons are energy-efficient and biologically plausible neurons models. The introduced deep spiking DFR model is energy-efficient and has the capability of analyzing time series signals. The corresponding field programmable gate arrays (FPGA)-based hardware implementation of such deep spiking DFR model is introduced and the underlying energy-efficiency and recourse utilization are evaluated. Various spike encoding schemes are explored and the optimal spike encoding scheme to analyze the time series has been identified. To be specific, we evaluate the performance of the introduced model using the spectrum occupancy time series data in MIMO-OFDM based cognitive radio (CR) in dynamic spectrum sharing (DSS) networks. In a MIMO-OFDM DSS system, available spectrum is very scarce and efficient utilization of spectrum is very essential. To improve the spectrum efficiency, the first step is to identify the frequency bands that are not utilized by the existing users so that a secondary user (SU) can use them for transmission. Due to the channel correlation as well as users' activities, there is a significant temporal correlation in the spectrum occupancy behavior of the frequency bands in different time slots. The introduced deep spiking DFR model is used to capture the temporal correlation of the spectrum occupancy time series and predict the idle/busy subcarriers in future time slots for potential spectrum access. Evaluation results suggest that our introduced model achieves higher area under curve (AUC) in the receiver operating characteristic (ROC) curve compared with the traditional energy detection-based strategies and the learning-based support vector machines (SVMs).
End-to-End Game-Focused Learning of Adversary Behavior in Security Games

Stackelberg security games are a critical tool for maximizing the utility of limited defense resources to protect important targets from an intelligent adversary. Motivated by green security, where the defender may only observe an adversary's response to defense on a limited set of targets, we study the problem of learning a defense that generalizes well to a new set of targets with novel feature values and combinations. Traditionally, this problem has been addressed via a two-stage approach where an adversary model is trained to maximize predictive accuracy without considering the defender's optimization problem. We develop an end-to-end game-focused approach, where the adversary model is trained to maximize a surrogate for the defender's expected utility. We show both in theory and experimental results that our game-focused approach achieves higher defender expected utility than the two-stage alternative when there is limited data.

We study the predict+optimise problem, where machine learning and combinatorial optimisation must interact to achieve a common goal. These problems are important when optimisation needs to be performed on input parameters that are not fully observed but must instead be estimated using machine learning. We provide a novel learning technique for predict+optimise to directly reason about the underlying combinatorial optimisation problem, offering a meaningful integration of machine learning and optimisation. This is done by representing the combinatorial problem as a piecewise linear function parameterised by the coefficients of the learning model and then iteratively performing coordinate descent on the learning coefficients. Our approach is applicable to linear learning functions and any optimisation problem solvable by dynamic programming. We illustrate the effectiveness of our approach on benchmarks from the literature.
Finding Most Compatible Phylogenetic Trees over Multi-State Characters
Authors: Korhonen Tuukka , Järvisalo Matti
Published: June 2020

The reconstruction of the evolutionary tree of a set of species based on qualitative attributes is a central problem in phylogenetics. In the NP-hard perfect phylogeny problem the input is a set of taxa (species) and characters (attributes) on them, and the task is to find an evolutionary tree that describes the evolution of the taxa so that each character state evolves only once. However, in practical situations a perfect phylogeny rarely exists, motivating the maximum compatibility problem of finding the largest subset of characters admitting a perfect phylogeny. Various declarative approaches, based on applying integer programming (IP), answer set programming (ASP) and pseudo-Boolean optimization (PBO) solvers, have been proposed for maximum compatibility. In this work we develop a new hybrid approach to solving maximum compatibility for multi-state characters, making use of both declarative optimization techniques (specifically maximum satisfiability, MaxSAT) and an adaptation of the Bouchitt'e-Todinca approach to triangulation-based graph optimization problems. Empirically our approach outperforms in scalability the earlier proposed approaches w.r.t. various parameters underlying the problem.
FourierSAT: A Fourier Expansion-Based Algebraic Framework for Solving Hybrid Boolean Constraints

Published: June 2020

The Boolean SATisfiability problem (SAT) is of central importance in computer science. Although SAT is known to be NP-complete, progress on the engineering side—especially that of Conflict-Driven Clause Learning (CDCL) and Local Search SAT solvers—has been remarkable. Yet, while SAT solvers, aimed at solving industrial-scale benchmarks in Conjunctive Normal Form (CNF), have become quite mature, SAT solvers that are effective on other types of constraints (e.g., cardinality constraints and XORs) are less well-studied; a general approach to handling non-CNF constraints is still lacking. In addition, previous work indicated that for specific classes of benchmarks, the running time of extant SAT solvers depends heavily on properties of the formula and details of encoding, instead of the scale of the benchmarks, which adds uncertainty to expectations of running time.To address the issues above, we design FourierSAT, an incomplete SAT solver based on Fourier analysis of Boolean functions, a technique to represent Boolean functions by multilinear polynomials. By such a reduction to continuous optimization, we propose an algebraic framework for solving systems consisting of different types of constraints. The idea is to leverage gradient information to guide the search process in the direction of local improvements. Empirical results demonstrate that FourierSAT is more robust than other solvers on certain classes of benchmarks.
