In the current investigation we classified participants as inhibitors or non-inhibitors depending on the extent to which they showed conditioned inhibition in a context that had been used for extinction of a conditioned response. This classification enabled us to predict participant responses in a second experiment which used a different design and a different experimental task. In the second experiment a feature-negative discrimination survived reversal training of the feature to a greater extent in the non-inhibitors than in the inhibitors and this result was supported by Bayesian analyses. We propose that the fundamental distinction between inhibitors and non-inhibitors is based on a tendency to utilise first-order (direct associations) or second-order (occasion-setting) strategies when faced with ambiguous information and that this classification is a stable individual differences attribute.

Basically the decision to buy bottled water by consumers is influenced by many factors such as the quality of a product, brand, taste, lifestyle and the range of promotion made by the company. Driven by the needs that exist within a person and the desire that the needs in a person are affected if the consumer shows a sense of fun that ultimately leads to loyalty. Loyal customers are more valuable than customers who are just satisfied. For loyal customers will always use the product of all time and is a source of revenue and Aicos company in this case have been concerned about factors that can affect consumers in buying decisions. In this research, the research describes several variables that influence consumer purchase decision that is product quality, price, promotion. The quality of the product, the price, the promotion is called the independent variable and the purchase decision is called the dependent variable. Through the research results obtained by researchers, the researchers drew the conclusion that the variables free of price and promotion have a significant effect on purchasing decision because the value of sig <0,05. While for the independent variable of product quality has no significant effect with purchase decision because sig value> 0,05. This is because the consumers who have been interviewed stated that the drinking water products in their quality packaging are almost the same.

Possible Observation of a Second Kind of Light
Authors: Kühne Rainer
Published: March 2019

According to classical electrodynamics, sunlight that is passed through an iron layer can be detected with the naked eye only if the thickness of the layer is less than 170nm. However, in an old experiment, August Kundt was able to see the sunlight with the naked eye even when it had passed an iron layer with thickness greater than 200nm. To explain this observation, we propose a second kind of light which was introduced in a different context by Abdus Salam. A tabletop experiment can verify this possibility.
Combining Active Inference and Hierarchical Predictive Coding: A Tutorial Introduction and Case Study
Authors: Millidge Beren
Published: March 2019

This paper combines the active inference formulation of action (Friston, 2009) with hierarchical predictive coding models (Friston, 2003) to provide a proof-of-concept implementation of an active inference agent able to solve a common reinforcement learning baseline -- the cart-pole environment in OpenAI gym. It demonstrates empirically that predictive coding and active inference approaches can be successfully scaled up to tasks more challenging than the mountain car (Friston 2009, 2012). We show that hierarchical predictive coding models can be learned from scratch during the task, and can successfully drive action selection via active inference. To our knowledge, it is the first implemented active inference agent to combine active inference with a hierarchical predictive coding perceptual model. We also provide a tutorial walk-through of the free-energy principle, hierarchical predictive coding, and active inference, including an in-depth derivation of our agent.
A network approach to rebel fighting durations in civil wars
Authors: Metternich Nils W , Wucherpfennig Julian
Published: March 2019

Recent research on multi-actor civil wars highlights that rebel organizations condition their conflict behavior on that of other rebel organizations, with competition and free-riding constituting the core theoretical mechanisms. We provide a new actor-centric approach to explicitly model strategic interdependence in multi-actor civil wars. We argue that competitive dynamics dominate strategic behavior between rebel organizations, but these can be offset by incentives to free-ride in cases where the underlying incompatibility displays public good characteristics. Based on a network game theoretic model, we derive a statistical framework that allows for a direct test of strategic interdependence. We find that the estimated duration interdependence is positive, that is weaker in secessionist conflicts, and that modeling this interdependence explicitly outweighs existing empirical measures of interdependence (e.g. number of organizations). Finally, we demonstrate that the model fit of rebel organizations' fighting durations can be improved by taking strategic interdependence into account.
Towards an Idiographic Education
Authors: Savi Alexander Olof
Published: March 2019

Picture education as a long chain of interventions in a self-organizing developmental system. On the one extreme, such educational sequences can be identical for each and every student, whereas on the other extreme, each sequence may be perfectly tailored to the individual. The latter is what is meant with idiographic education. All educational programs can be seen to lie somewhere in between those extremes, and in this book, methods are explored that may help increase the tailoring of education.The book covers advances in three fundamental approaches. First, it discusses and illustrates an experimental approach: online randomized experiments, so-called A/B tests, that enable truly double-blind evidence-based educational improvements. Second, it introduces a diagnostic approach: a scalable method that helps identify students’ misconceptions. Third and finally, it introduces a theoretical approach: a formal conceptualization of intelligence that permits a novel educational, developmental, and individual perspective, and that may justify and ultimately guide the tailoring of education.

Published: March 2019

Background: Late diagnosis of HIV is associated with poor outcomes and increased cost. Novel HIV testing promotion strategies may reduce late diagnosis. The purpose of this study was to determine the timeliness of HIV testing in Newfoundland and Labrador (NL), missed opportunities for testing, and barriers to HIV testing. Methods: Demographic and clinical information from individuals diagnosed with HIV in NL from 2006–2016 was retrospectively reviewed. Patients were also invited to participate in semi-structured interviews regarding knowledge about HIV transmission, risk associated with their behaviour, testing decision making, and testing opportunities. Results: Fifty-eight new HIV diagnoses occurred during the study period: 53/58 (91.4%) were male and 33/58 (56.9%) were men who have sex with men. The mean age at diagnosis was 40.6 (SD 11.05) years. CD4 count at diagnosis ranged from 2 to 1,408 cells/mm3, with a mean of 387 cells/mm3. For 39/58 (67.2%) of individuals, the first-ever HIV test was positive. Of the 58 patients, 55 (94.8%) had had health care contact within the 5 years prior to diagnosis (mean 13.7 contacts). Heterosexual men were more likely to present with a late diagnosis ( p = 0.049). Ten (17.2%) individuals agreed to an interview. Thematic analysis revealed that barriers to testing were stigma, negative health care interactions, denial, and fear of the diagnosis. Conclusions: HIV diagnosis is made later in NL than in other Canadian provinces. Late diagnosis may be prevented if HIV testing became a routine testing procedure.

Authors: Santhakumar Kannappan , Viswanath Valikala
Published: March 2019

The control of infections and maintenance of hygienic conditions are of central importance and the insights gained through several investigations have practical significance today. In contrast, the maintenance of environment and surface disinfection is still controversial and demands novel disinfectants to meet the required criteria. The healthcare centers are fraught with various microorganisms and serve as a point source for multidrug resistance in patients which is more critical to treat. Therefore, it has begun a comprehensive plan in hospitals to focus on disinfection and maintenance of hygiene which is not always appreciated. The urgency to determine the effectiveness of disinfectants is often questioned. The review article shows how the existing problems could be solved by a systematic approach and reports on effective evaluation studies that meet the requirements.

Authors: De Oliveira Glaunara Mendonça , Soares Neiva Maria Machado
Published: March 2019

A arte de rua tem conquistado espaço significativo em Manaus (AM). O mural de Raí Campos – Raiz – foi selecionado como corpus para este trabalho por seu caráter de gênero discursivo híbrido que dialoga com outros: a fotografia de Christian Braga (2017), a fábula do Beija-flor e o poema “Arte de Raiz”, de Celdo Braga (2017). Por metodologias tomam-se a Análise de Discurso Crítica (FAIRCLOUGH, 2001 [1992], 2003), para considerar os aspectos relacionados às práticas discursivas e sociais; e a Gramática do Design Visual – GDV (KRESS e van LEEUWEN, 1996, 2006), para análise de gêneros multissemióticos, por meio das categorias dos Significados Composicional, Representacional e Interativo. A análise revelou uma relação interdiscursiva e intertextual entre os gêneros, evidenciando o caráter híbrido e multimodal do mural e o cruzamento de discursos nele presentes, conduzindo ideologias que representam o mundo dos participantes, e a representação da etnia Tembé em um cenário híbrido urbano.

Start of Higher School in Crimea: Taurida University (1918–1920)
Authors: Filimonov Sergey B.
Published: March 2019

October 14, 2018 marked the 100th anniversary of the inauguration of the first university in Crimea, which initially, in 1918–1920, was called the Taurida University, and now is V.I. Vernadsky Crimean Federal University. In this regard, it is useful to recall the main stages of the history of the university. Of particular interest is the history of Taurida University in the years of the Civil War, when its teachers were the greatest scientists who fled from the Bolshevik terror from the university centers of the former Russian Empire to the “white” Crimea. But it was precisely this period that received the least coverage in the literature published in the twentieth century. The main reason for this is the lack of a sufficient source base. After all, the pre-war university archive was lost, and the main source for a long time remained only two volumes of the “News of the Tauride University” published in 1919 and 1920. The noted narrowness of the source base forced researchers to look for additional sources of information. Attention was drawn to the archives of institutions, organizations and individuals associated with the university in the initial period of its existence, as well as sources of personal origin (diaries of Academician V.I. Vernadsky, memories of his son, Professor G.V. Vernadsky, etc.).

In the late 1990s, the author of the article was fortunate enough to reach the richest unique source that remained untapped by researchers on the history of the Crimean intelligentsia, science and culture in 1917–1920 – Crimean newspapers during the Civil War. On their pages, it was possible to find not only chronicle notes to recreate the missing pages of the history of Taurida University and existing scientific societies, not only information about the participation of university professors in the activities of numerous Crimean scientific organizations, but also publications of a number of leading scientists that remained unknown.

The present article is based mainly on these newspapers, which have long become a bibliographic rarity.

The paper addresses the role of universities in the generation, use and dissemination of knowledge, analyzes principles and ways to develop science and education at universities. It is emphasized that the University is becoming an active player not only in training, but also in the production of a new knowledge, in its dissemination and implementation through innovation. At the same time, it is necessary to note that the conditions of the Far North impose a unique specificity on the work of the University and its scientific and innovative activities.

For Murmansk Arctic State University (MASU), scientific and research work is one of the most dynamically developing components that create development potential. The paper presents the range of MASU’s scientific activities which includes 3 main spheres: natural science, technical science, social science, and Humanities. The authors dwell on the students’ and postgraduates’ scientific activities, consider the youth scientific organizational structure.

As a flagship University, MASU is implementing a strategic development project “MASU is Scientific and Technological Hub of the Region” formed with the direct support of the Government of the Murmansk region. Within the framework of the project, an information and analytical platform was created in MASU under the partnership with Kola Science Center RAS (IAP MASU-KSC). This platform is an integrating consulting mechanism including a set of technological, commercial and marketing solutions for the development and implementation of innovative products and technologies in organizations operating in the field of ensuring a comfortable human presence in the Far North.

As one of the priority goals of the strategic development of the University, the trajectory of the Arctic scientific and educational center (SEC) creation on the basis of MASU is highlighted. The key areas and ways to improve the efficiency of scientific and educational activities of MASU, as well as the expected results of the SEC are considered.

The paper considers the specifics of the spatial and functional localization of regional education subsystems in the Russian Federation. Such subsystems include pre-school education, school education, secondary vocational education, and higher education. A set of indicators is suggested that can be used to assess the development stage of these subsystems. Cluster analysis made it possible to group the country’s regions according to the parameters of the education system, and determine the major characteristics of these groups (virtual clusters). Development tendencies of the education subsystems in the regions of each virtual cluster from 2010 to 2016 were analysed to identify the strong and the weak points of each group.
Modern Doctoral Education in Russia: Current Directions of Development
Authors: Bednyi Boris I. , Chuprunov Evgeny V.
Published: March 2019

The article is based on the materials of the report presented at the plenary session of the Professors’ Forum 2019 “Science. Education. Regions” of the All-Russian Public Organization “Russian Professorial Assembly” (Moscow, Peoples’ Friendship University of Russia, February 6, 2019). In the context of the problems that were discussed at the Forum, three points have been formulated, which, according to the authors, determine the priority areas in the development of modern Russian doctoral education: 1. Doctoral education and dissertation. Since the institution of doctoral education is the main resource for training professional researchers and university teachers, postgraduate programs should be aimed at the defense of PhD (Candidate of Sciences) theses. 2. The educational component of postgraduate programs. Doctoral education should be developed as a research program that includes an educational component, rather than as an educational program that includes a research component. 3. Training of research personnel for the regions. In the context when budgetary resources for supporting doctoral education are concentrated in the country’s leading universities, the problem of reproducing highly qualified personnel at regional universities, which do not have such a status, is of particular relevance. The article proposes some specific measures to improve the national system for training of highly qualified personnel in postgraduate schools.

The article focuses on the issues of the formation of a conceptually new target model of a regional flagship university. Based on the experience of the formation and development of the Murmansk Arctic State University, which acquired the status of a flagship one in 2017, the authors analyze the origins of the formation of the model, its specificity, which is substantively and formally defined in the parameters of the Arctic perspective. The major intensively developing areas of MASU’s activity in the past two years have been focuses on two important factors of regional development, implemented in the form of two strategic flagship university projects. The first strategic project – “MASU is the scientific and technological hub of the region” – is aimed at solving the most acute regional task of effectively using both the economic and scientific / innovative potential of the region. The second strategic project – “Creative City is a Territory of Development” – reflects the interaction of the creative communities of the region, the Russian Federation and the world with prospect consumers represented by the regional government, municipalities, institutions and industrial enterprises. MASU is the main platform for combining a variety of strategies and searches aimed at changing urban and township sociocultural spaces, an integrator of various areas of design, creative technologies and cultural practices that affect the improvement of the quality of life and human capital development. The key role is determined by the role of the flagship university as a driver of the regional socio-economic development. The developing dialogue between the university, business and government is affirmed as an indispensable condition for the University’s successful functioning and a pledge for its further development.

Published: March 2019

Russia owns world largest reserves of titanium- magnetite and ilmenite- titanium- magnetite ores. Following the stepby-step inclusion into metallurgical processing of titanium- magnetite raw materials, the matter of maximum extraction of iron, vanadium and titanium becomes more and more actual. Kachkanar group of deposits of titanium- magnetite ores consists of two deposits: Gusevgoskoe and Sobstvenno-Kachkanar. At present JSC EVRAZ NTMK uses titanium- magnetite sinter and pellets, produced of Gusevgorskoe deposit ores. To make up the dropped out capacities and to keep the volume of mined ore at the level of 55 m t/year, it is planned to put into operation the reserved Sobstvenno-Kachkanar deposit. To process the titanium- magnetite ores of this deposit, their specific peculiarities should be taken into consideration. In particular, the increased TiO2content in iron ore concentrate up to 3.4% might require corrections of the BF technology. In this connection a study of metallurgical properties of lump iron ore raw materials with different titanium dioxide content was carried out. To clarify the pellets phase components a method of X-ray-phase analysis was used. The studies were done at CKP “Ural-M” equipment in the Institute of Metallurgy, Ural branch of Russian academy of Sciences. It was determined that pellets chemistry was represented by hematite (from 77 up to 89%), magnetite (from 2.84 up to 10.44%), complicated diopside (from 2 up to 10%), as well as in a small amount by quartz, hedenbergite, corundum, rutile, ferro-periclase, ilmenite, wollastonite, α-Fe, wustite. Results of viscosity calculation of obtained slags showed that it is within a range, typical for real BF slags viscosity. The obtained values of slag viscosity do not offer problems with slag regime of BF heat. It was shown, that increase of titanium dioxide content in pellets does not give rise to quality deterioration of iron ore raw materials preparation to BF heat as volume of introduced concentrate with increase TiO2content into the materials is increasing. Increase of hot strength and pellets temperature of beginning of softening, the pellets having increased titanium dioxide content, will positively affect main technical and economic indices of BF heat – coke rate and productivity, that was confirmed by BF indices calculation by application of balance logical and statistical model of BF process.

Information about character of burden materials behavior inside a blast furnace at its different horizons enables to increase control efficiency of BF heat running. The elaborated complex of methodologies for carbon materials and iron ore raw materials properties study enables to simulate their behavior at the horizon of iron ore materials reducing, in the viscoplastic zone, at the horizon of iron ore raw materials smelting and its interaction with coke filling. A vertical electric resistance shaft furnace with a tube carbon heater was used as a base equipment for simulation of burden behavior in the reduction zone and smelting zone, as well as for simulation of iron ore burden melt outflow through coke filling. Burden materials preparation to the experiment concluded in crushing of iron ore component followed by 3–5 mm fraction extraction and a mixing it with 3–5 mm fraction of brown coal semi-coke in relation 2:1 for further heating-reduction treatment. The heating-reduction treatment of the mixture charged in the electric furnace simulates the reducing zone and is carried out by a slow heating of the iron ore component and reducing agent mixture from 20 up to 980–1020 ºС. The methodology of determination of lump carbon materials combustibility in the highly heated air blast flow was developed for the complex of equipment based on the shaft electric resistance furnace and aimed at testing of burning process of carbon samples of technological fuels. The combustibility was determined under conditions of burnt sample heating in the temperature range from 500 up to 1500 °C with an accuracy of ±10 °С. The temperature of air blast flow (21 % vol. of oxygen at natural moisture) was set in the range from 120 up to 1200 °С and was kept with an accuracy of ±12 °С. The burnt sample mass, volume of air blast and its velocity was correlated to obtaining of complex non-dimensional Re factor (Reinolds number) more than 100, that guaranteed a reliable process running in the combustion area with no risk of transferring to gasification process. Based on GOST 26517–85 (“Iron ores, sinter and pellets”) a methodology was elaborated for determining of parameters of iron ore materials status in the viscoplastic zone. The methodology comprises heating of preliminary reduced sample of a tested iron ore material in an inert gas and determination of softening temperature and smelting end by a hard rod sinking into the material layer under external pressure action. The temperature at which the layer shrinkage reaches level of 2% during heating, was taken as the softening temperature of the iron ore material. The sinking of the rod into the material by 80% was taken as the temperature of the beginning of the material melting. The interval softening-melting was determined as the difference between melting temperature and softening temperature (at sample shrinkage by 2 %).

Application of pulverized-coal fuel in BF production results in changes of blast furnace heat operation, in particular, in hot metal temperature and silicon content in it changes, that effects the energy efficiency of “BF shop – BOF shop” complex operation. Isolated consideration of energy utilization by facilities (blast furnace, basic oxygen furnace) without taking into account their energy-technological ties does not provide steel smelting rational solutions obtaining. An exergy analysis of silicon content in hot metal and its temperature influence on energy efficiency of “BF shop – BOF shop” complex operation accomplished by application of the elaborated method of calculation of complete energy balance of “BF shop – BOF shop” system under existing conditions of pulverized-coal fuel application in Ukraine. It was shown, that silicon content decreasing down to level, which does not allow malfunctions of BF heat operation is strategically important for improving of energy efficiency of “BF shop – BOF shop” complex operation under conditions of pulverized-coal fuel application in BF production. It was determined, that under conditions of pulverized-coal fuel application in “BF shop – BOF shop” system, silicon content in hot metal decrease by 0.1% results in decreasing of exergy losses by 18–180 MJ/ton of steel, which is equivalent to standard fuel consumption decrease by 0.5–6.0 kg/ton of steel, increase of hot metal production by ~0.3–1.2 %. Hot metal temperature in blast furnace increase by 50 °С results in exergy losses decrease by 26–29 MJ/ton of steel, which is equivalent to standard fuel decrease by 0.9–1.0 kg/ton of steel.

Defects of metallurgy-originated steel (sub-cored bubbles, impurities, macro- and micro-segregations of chemical elements, nonmetallic inclusions) to a large extent determines the faultiness of metal rolled products. The processes of chemical elements segregation in steel macro- and micro volumes considerably influence its quality. Reasons of microphysical dendrite segregation originating in steels of welding purpose of Св-09Г2С and Св-08ГНМ type considered. Mechanism of dendrites formation studied as well as the segregation degree of chemical elements along the continuously casted billet cross section. To estimate the segregation degree a criteria was used – the segregation coefficient, determined as relation of chemical elements mass shares in different micro-areas (dendrites, inter-dendrite gaps) of continuously casted billet cross section to those elements content by a ladle analysis of a heat or one another in different micro-areas. A heredity of segregation transfer from CC billet to finished wire rod of Св-08Г2С and Св-08ГНМ steels studied. It was determined, that decrease of the number of bainite-martensite areas as a result of decrease of dendrite segregation of chemical elements takes place by minimization within grade chemical composition of both main alloying element and impurities ones. Besides an additional alloying of steel by boron takes place based on boron to nitrogen relation at the level of B/N = 0,8±0,15. It was shown that to decrease the inter-dendrite segregation it is necessary to elaborate and implement effective steel modifying by calcium and REMs regimes as well as electro-magnetic stirring during continuous casting.

At small-capacity production of pipes a process of pipes reducing at radial-forging machines can be effective for expanding of pipes assortment by diameter and wall thickness. Results of pilot work on hot reducing at radial-forging machine SKK14 of pipes, made of corrosion-resistant steels 12Х18Н10Т and 10Х23Н18. Based on analyses of known recommendations on pipes forming during reducing by longitudinal rolling at reducing mills, as well as at radial-forging and rotary-forging machines, it was recommended to use a known dependence Sр = S0/[1 – 0,0044(D0 – Dр)], usually applied for pipes rolling conditions at reducing mills, for predicting of reduced pipe wall thickening. To determine the pipes internal surface quality, a hot reducing of pipes made of 12Х18Н10Т steel was accomplished using different technological routes and taking into consideration a possibility of forming folds and laps on the surface. It was established that longitudinal folds (wrinkles) are not formed on the pipe internal surface at the pipe outer diameter decreasing by less than 30%, while the longitudinal folds (wrinkles) are formed at decreasing of the pipe outer diameter by more than 45%. Forging folds can be formed on the pipe internal surface at pipe outer diameter decreasing by more than 60%.
