Three-dimensional grain angle measurement of softwood (Hinoki cypress) using near infrared spatially and spectrally resolved imaging (NIR-SSRI)
Authors: Ma Te , Inagaki Tetsuya , Tsuchikawa Satoru
Published: April 2019

As the strength of wood is greatly affected by its three-dimensional (3D) grain angles (the dive angle and the surface angle), the wood industry today requires automatic, rapid, and robust measurement techniques for measuring them simultaneously. In the present study, a near infrared spatially and spectrally resolved imaging (NIR-SSRI) system was designed in a line scan model, mainly including an NIR hyperspectral imaging camera and a halogen spotlight source (Ø 1 mm). Spatially resolved diffuse reflectance images at three target wavelengths (1002 nm, 1217 nm, and 1413 nm) were obtained from Hinoki cypress [Chamaecyparis obtusa (Siebold & Zucc.) Endl.] samples at various (0°, 3°, 6°, … 45°) dive angles and surface angles (0°, 3°, 6°, … 45°). The scattering patterns caused by the “tracheid effect” were almost elliptical. Subsequently, nonlinear least squares fitting was used to determine their eccentricities (e) and rotation angles (θ). The e values at each selected wavelength were highly correlated with the dive angle reference values; and the global identification model developed using Gaussian process regression (GPR) under five-fold cross-validation (CV) reached a determination coefficient (r
2) of 0.98 with a root mean square error (RMSE) of 2.2°. On the other hand, local surface angle identification models developed using linear regression analysis achieved determination coefficients higher than 0.90 on r
2 and an RMSE of CV lower than 3.8° when the dive angle was lower than 30°.
New drum-chipping technology for a more uniform size distribution of wood chips
Authors: Gard Timmerfors Jessica , Sjölund Torbjörn , Jönsson Leif J.
Published: April 2019

Wood chips from a novel type of drum chipper were compared to wood chips from a conventional disc chipper in an evaluation based on demonstration-scale and industrial-scale machinery. The evaluation was performed as the wood chippers were used as production machines in a kraft pulp mill using softwood. The average bulk density of the wood chips from the disc chipper and the drum chipper was similar and within the range of 138–140 kg/m3. The size distribution of the wood chips was investigated using a conventional screening method, and by using an automatized image-analysis system based on laser scanning. The average length was set to be the same, but the wood chips from the drum chipper had a more uniform length. The average thickness was similar, but the drum chipper generated slightly more thinner wood chips. Compared to the disc chipper and using the screening method, the drum chipper generated a similar fraction of oversized and overthick wood chips, 51% more large accept chips, 11% more total accept chips, and 74% less pin chips and fines. Image analysis resulted in similar data. The results indicate that drum chippers warrant further attention as an alternative to conventional industrial-scale disc chippers.

Effect of Coal Ash on Fe-Based Oxygen Carrier in Coal Char Chemical Looping Gasification
Authors: Liu Yongzhuo , Zhang Xintao , Gao Minggang , Hu Xiude , Guo Qingjie
Published: April 2019

Chemical looping gasification (CLG) is a cost-effective alternative to the traditional fossil conversion process. In this article, the effects of three different types of coal ash on Fe-based oxygen carrier in coal char CLG were investigated. The composition of coal ashes and the microstructure of Fe4Al6 oxygen carrier were characterized by SEM-EDS, XRD and BET. The effects of different components of coal ash (SiO2, CaO, and K2O) were examined, and their effect mechanisms were analyzed. The findings suggested that the effect of coal ash on Fe4Al6 oxygen carrier could be divided into three aspects: (i) inhibition effect by forming low-melting-point compounds; (ii) enhancement effect through catalysis or formation of specific structure; and (iii) neutral effect by integrating with oxygen carrier. In addition, the formation of low-melting-point compounds, which is mainly due to SiO2 and CaO, was found to cause sinter and agglomeration of oxygen carrier. Moreover, potassium salts were found to either act as catalysts or cause the formation of K-Fe-O compounds; they promoted the release of lattice oxygen from oxygen carrier while enhanced oxygen carrier’s stability. The findings suggested that coal ash containing high content of K2O and Fe2O3 could enhance the performance of oxygen carrier during CLG.
Robinson’s conjecture for classical groups
Authors: Feng Zhicheng , Li Conghui , Liu Yanjun , Malle Gunter , Zhang Jiping
Published: April 2019

Robinson’s conjecture states that the height of any irreducible ordinary character in a block of a finite group is bounded by the size of the central quotient of a defect group.
This conjecture had been reduced to quasi-simple groups by Murai.
The case of odd primes was settled completely in our predecessor paper.
Here we investigate the 2-blocks of finite quasi-simple classical groups.

The Ivanov regularized Gauss–Newton method in Banach space with an a posteriori choice of the regularization radius
Authors: Kaltenbacher Barbara , Klassen Andrej , Previatti de Souza Mario Luiz
Published: April 2019

In this paper, we consider the iteratively regularized Gauss–Newton method, where regularization is achieved by Ivanov regularization, i.e., by imposing a priori constraints on the solution.
We propose an a posteriori choice of the regularization radius, based on an inexact Newton/discrepancy principle approach, prove convergence and convergence rates under a variational source condition as the noise level tends to zero and provide an analysis of the discretization error.
Our results are valid in general, possibly nonreflexive Banach spaces, including, e.g.,

The theoretical findings are illustrated by numerical experiments.
Rigorous Eigenmode Derivations and Spectral Analysis for Step-Index Confocal Parabolic Optical Fibers
Authors: Ikpeazu Emeka V.
Published: April 2019

For quite some time, the geometry-dependence of electric fields confined in two-dimensional systems of propagation has been known. We explore a lesser known way in which one can confine light, parabolically. One can use this method to understand the different forms modes take in such fibers and the appropriate eigenfunction for spectral analysis. In this paper, a fiber with a parabolic core and a circular cladding for the preservation of coaxiality are proposed.
MYT1L mutation in a patient causes intellectual disability and early onset of obesity: a case report and review of the literature
Authors: Al Tuwaijri Abeer , Alfadhel Majid
Published: April 2019

Background

Obesity has become one of the greatest health risks worldwide. Recently, there was an explosion of information regarding the role of the central nervous system (CNS) in the development of monogenic and syndromic obesity.

Case presentation

Over the last decade, terminal and interstitial submicroscopic deletions of copy number variants (CNVs) in 2p25.3 and single nucleotide variants (SNVs) in myelin transcription factor 1 like (MYT1L) were detected by genome-wide array analysis and whole exome sequencing (WES) in patients with a nonspecific clinical phenotype that commonly includes intellectual disability (ID), early onset of obesity and speech delay. Here, we report the first Saudi female patient with mild to moderate ID, early onset of obesity and speech delay associated with a de novo pathogenic SNV in the MYT1L gene (c. 1585G>A [Gly529Arg]), which causes an amino acid change from Gly to Arg at position 529 that leads to mental retardation, autosomal dominant 39.
Distributive Justice and the Sustainable Development Goals: Delivering Agenda 2030 in India
Authors: Ramanujam Nandini , Caivano Nicholas , Agnello Alexander
Published: April 2019

The sustainable development goals (SDGs) present a real opportunity to direct India towards a path of equality and equity. This article posits that India’s plans to achieve the millennium development goals by the end of their term in 2015 faltered because reforms designed to alleviate poverty and achieve equitable growth did not adequately address weaknesses in institutions of accountability, which undermined the reform agenda. These institutions, which include Parliament and the judiciary, exist in part to ensure that actions taken by public officials are subject to oversight so that government initiatives meet their stated objectives. As India shifts its attention to Agenda 2030, its renewed commitment to institutional reforms represents an occasion for the state to address the inequalities in income and the resulting human development concerns. For the government to achieve the SDGs, this article suggests that India must integrate what we refer to as a baseline conception of distributive justice within its plans, which can account for structural barriers to its development arising from ineffective institutions of accountability and provide the poor with a route towards individual empowerment.
“Fight Like a Girl”: Tattoos as Identity Constructions for Women Living with Illness
Authors: Koller Veronika , Bullo Stella
Published: April 2019

In this article, we explore the functions that tattoos worn by women with breast cancer or endometriosis have in constructing identities for the wearer and conceptualise the respective illness. Drawing on previous literature on multimodal communication, tattoos and illness, we analyse a sample of 59 different tattoos for their ideational function in constructing identities. A social semiotic analysis shows that lexemes, images, type fonts and intertextuality work together to construct dominant identities for the women wearing the tattoos: as a fighter or warrior, or as a sufferer. The first, metaphoric, identity shows hybrid gendering and constructs the illness as an adversary, while the identity as sufferer often has religious overtones, particularly for breast cancer tattoos. Subversive identities centre on despair or rationality, and as such constitute an alternative to social imperatives of either staying strong and fighting the illness or accepting one’s fate. We close by discussing in how far the tattoos do justice to the complexity of living with an illness and how our research shows the need to include visual stimuli in medical consultations.
Spectral stability of nonlinear gravity waves in the atmosphere
Authors: Schlutow Mark , Wahlén Erik , Birken Philipp
Published: April 2019

We apply spectral stability theory to investigate nonlinear gravity waves in the atmosphere. These waves are determined by modulation equations that result from Wentzel-Kramers-Brillouin theory. First, we establish that plane waves, which represent exact solutions to the inviscid Boussinesq equations, are spectrally stable with respect to their nonlinear modulation equations under the same conditions as what is known as modulational stability from weakly nonlinear theory. In contrast to Boussinesq, the pseudo-incompressible regime does fully account for the altitudinal varying background density. Second,we show for the first time that upward-traveling non-plane wave fronts solving the inviscid nonlinear modulation equations, that compare to pseudo-incompressible theory, are unconditionally unstable. Both inviscid regimes turn out to be ill-posed as the spectra allow for arbitrarily large instability growth rates. Third, a regularization is found by including dissipative effects. The corresponding nonlinear traveling wave solutions have localized amplitude. As a consequence of the nonlinearity, envelope and linear group velocity, as given by the derivative of the frequency with respect to wavenumber, do not coincide anymore. These waves blow up unconditionally by embedded eigenvalue instabilities but the instability growth rate is bounded from above and can be computed analytically. Additionally, all three types of nonlinear modulation equations are solved numerically to further investigate and illustrate the nature of the analytic stability results.
Why We Shouldn’t Pity Schrödinger’s Kitty: Revisiting David Lewis’ Worry About Quantum Immortality in a Branching Multiverse
Authors: Lenart Bartlomiej A.
Published: April 2019

David Lewis cautions that although a no-collapse interpretation of quantum mechanics entails immortality for trans-world selves, the nature of the branching leaves us crippled, lonely, deathly ill (although never dead), and mentally infirm, meaning that immortal life, on such terms, amounts to an existence in eternal torment. This paper argues that the problem Lewis points to is in fact one of individuation and that a synthesis of Lewis’ own notion of perdurance and Robert Nozick’s closest continuer theory, when cast in the mould of a deterministic multiverse (as conceived by the Oxford quantum physicist David Deutsch), individuates trans-world selves in such a way as to allow to prune the infinitesimal expectation of a miserable eternal existence from the histories of most trans-world agents. Thus, contrary to Lewis’ warning that if personal identity is a trans-world notion, then we should all shake in our shoes, this paper argues that even if we are trans-world selves, we almost certainly have nothing to worry about.

Published: April 2019

Intelligenz ist wichtig für schulischen Erfolg. Fördert Beschulung jedoch auch die Intelligenz? In diesem Übersichtsartikel präsentieren wir Evidenz dafür, dass sowohl die Schulbesuchsdauer als auch die Beschulungsqualität die Leistung in Intelligenztests beeinflussen. Zudem werden differentielle Effekte beleuchtet. Der Beschulungseffekt ist für akademische Ausbildungsgänge ausgeprägter als für nicht-akademische und zeigt sich in verschiedenen Intelligenzfacetten und Altersgruppen, wobei er für jüngere Kinder am stärksten zu sein scheint. Die Beschulungsdauer ist mit Alterseffekten auf die Intelligenz konfundiert, und verschiedene Beschulungszweige bringen das Problem eines selektiven Intakes von Schülern mit sich. Daher stellt der vorliegende Beitrag außerdem Untersuchungs-Designs vor, mit deren Hilfe diese Probleme gelöst werden konnten. Abschließend wird resümiert, dass der Beschulungseffekt kein Artefakt darstellt, sondern die Folge einer „echten“ Intelligenzsteigerung ist.
Use and efficacy of homeopathy in prevention and treatment of bovine mastitis
Authors: Zeise Johanna , Fritz Jürgen
Published: April 2019

Bovine mastitis is an important disease in dairy farming. As alternative therapy to antibiotics, whose use is seen as increasingly critical, farmer try to treat mastitis with homeopathy, for example. The present study examined i) whether homeopathic treatments for bovine mastitis can have positive treatment outcomes, ii) which treatments have been successful and under which conditions, iii) indications for future studies and applications for homeopathy to treat mastitis. 32 studies published to date have been evaluated. Assessment criteria and a rating score of 0 to 5 points were fixed for the appraisal. Healing and prophylaxis of mastitis were the primary focus to highlight the medication success and its framework for suitable mastitis therapy. The top eight studies of this quality ranking were subjected to differentiated evaluation. The selected studies showed a positive treatment outcome of homeopathy. Due to the homeopathic effect and the most used remedies in the selected studies, the medication should be chosen according to the homeopathic drug picture. With homeopathic drugs it was possible to reduce the antibiotic use by up to 75%. Some studies indicated that homeopathy might have a positive long-term effect. Furthermore, the results suggested a high self-healing ability in bovine mastitis.
Information retrieval algorithm of industrial cluster based on vector space
Authors: Li Rongsheng , Hassan Nasruddin
Published: April 2019

The current information retrieval research on industrial clusters has low precision, low recall ratio, obvious delay and high energy consumption. Thus, in this paper, a information retrieval algorithm based on vector space for industrial clusters is proposed. By optimizing the unlawful labels in the database network, dividing the web pages of the industrial cluster information database and calculating the keyword scores of the relevant information of the industrial cluster corresponding to a web page, a set of well-divided database pages is obtained, and the purification of the industrial cluster information database is realized. According to the purification of industrial cluster information database, RFD algorithm is used to extract the page data features of purified industrial cluster information database. The extracted results are substituted into the information retrieval, and the vectors composed of retrieval units are used to describe the information of various types of industrial clusters and each retrieval. The matching results of information retrieval are obtained by calculating the correlation between the information of industrial clusters and the query, and the information retrieval of industrial clusters is completed. Experimental results show that the algorithm has high precision and recall ratio, short retrieval time and low energy consumption.
Parametric model updating with frequency and MAC combined objective function of port crane structure based on operational modal analysis
Authors: Zhang Weiguo , Postolache Octavian
Published: April 2019

In FE modeling of port crane structures, errors may be caused due to the simplification of complicated components, unclear physical properties, local approximation and inaccurate boundary conditions. So it is very important to update the FE model accuracy according to the experiment model and results. However there are two major problems when solving the model updating of port crane structure, the one is the difficulty of collecting the structure modal parameters with traditional modal experiment method because of the large scale of port crane structure, the other is mismatching problem while updating processing due to most of the model updating method currently constructing the objective function only by frequency. In this paper, an operational modal analysis is adopted to estimate the modal parameters of port crane structure based on the operational condition. A parametric model updating methodology of finite element (FE) model is proposed to solve port crane structure model updating: a series of design parameters of the FE model of port crane structure are selected as the main factors based on the sensitivity analysis, the objective function is built by considering the frequency correlation and the modal assurance criterion (MAC) together, and finally a zero-order/first-order combination algorithm is utilized to get the final accurate FE model of port crane structure. Research results showed that methodology proposed in this paper has satisfied updating accuracy for port crane structure, which verifies that the proposed method is suitable for model updating problem of this kind of structure.

Two-sided altruism as a motive for intergenerational transfer
Authors: Fujiu Hiroshi , Yano Makoto
Published: April 2019

This paper reconsiders the role of altruism as a motive for an intergenerational transfer and characterizes the relationship between intergenerational transfers and altruism. The main finding is that transfers to children do not disappear even if altruism from parents to children weakens. The paper also shows that as altruism from children to parents becomes stronger, a transfer to children initially decreases and then increases once the degree of altruism is beyond a certain level; in other words, transfers may increase even if altruism from the transferee to the transferor becomes stronger. These findings sharply contrast with the common assumption in the existing literature that an intergenerational transfer is motivated by altruism from the transferor to the transferee.
The Teamwork Model: Proposing a Model for Studying Interprofessional Healthcare Teams
Authors: D'Angelo Matthew , Cervero Ronald , Durning Steven , Varpio Lara
Published: April 2019

This article was migrated. The article was marked as recommended. Patient safety is a preeminent healthcare concern in modern medicine. In the years since To Err is Human, researchers have found that the number of preventable deaths far exceeds 98,000; more accurately, 400,000 patients die each year from preventable healthcare errors. To combat the evolving patient safety crisis, a variety of organizations from Institute of Medicine to World Health Organization have called for the development of interprofessional healthcare teams. Interprofessional healthcare teams and teamwork have been a topic of discussion for over 40 years. And while some Interprofessional healthcare teams have been shown to be beneficial in some settings the success of these teams is not universal nor achieved in all healthcare settings. In short, research has found that interprofessional healthcare teams both improve and impede patient care. Building on this contradictions of interprofessional healthcare teams and teamwork, we present a model for the conceptualization of teamwork that could be readily applied to clinical experiences. This model is informed by the interprofessional healthcare team literature and relevant theories, and we believe will enable us to examine authentic interprofessional healthcare team interactions and identify moments when team interactions were breaking down, and reasons why those breakdowns were happening.
Analysis of the world surimi market, as well as resource constraints of production in Russia
Authors: Beletskiy A. A.
Published: April 2019

The fishery complex is one of the most significant in Russia, as it solves a number of extremely important issues: ensuring the country’s food security; synergistic effect of related industries (priority in shipbuilding and onshore production); obtaining export earnings (fishing companies catch more than people in our country can consume). However, Russia does not produce a number of goods for deep processing of fish, despite the availability of the resource base and the consumption market. One such product is a minced fish surimi, on the basis of which is preparing a lot of seafood. This article is devoted to the study and analysis of the world market and the production of surimi, as well as the actual topic of improving the competitiveness of seafood. The theoretical basis of this work is the methodology of strategic management in the global marketplace, developed by Dr. Vladimir Kvint. As a result of the analysis, it was determined that the main resource constraints of production in Russia are technological and technical aspects. In the country, the fishing plants tried to produce surimi from pollock, but they have not yet led to a sustainable positive result. The attention is also focused on market segments that may be of interest to potential Russian manufacturers. In addition, the article highlights the most promising areas that need to be developed for strategic leadership in the industry.
Strategic analysis of trends in the global fishing industry
Authors: Kudryashova K. L.
Published: April 2019

The article analyzes global strategic trends in the development of the fishing industry, whose most important role in terms of the successful development of society is increasingly recognized. For a number of priorities and indicators, the leading countries in the production, export and import of fish and fish products are indicated. The strategic vector of development of the fishing industry in Russia as a whole and, in particular, the Russian Far East has been substantiated. The competitive advantage of the region is the best resource base among all regions of Russia. The main objects of the fishing industry of Russia, determining its competitiveness in the global market, are concentrated in the Kamchatka Territory, Sakhalin Region, Primorsky and Khabarovsk Territories. The level of development of the productive forces of the fishing industry of the Far Eastern Federal District predetermines the role of  Russia in the most important economic space of the world – the Asia-Pacific region, where, since 1992, leaders of the fishing industry have been localized. The problem of realizing the strategic potential of the fisheries complex in Russia is complicated by the lack of capacity of the fishing fleet, port infrastructure, refrigeration and storage facilities onshore, and coastal fish processing plants.

Methodological provisions of building models of industrial enterprise development
Authors: Kostyukhin Yu. Yu.
Published: April 2019

In the age of information technology, characterized by a large amount of current data, the process of processing and structuring information has become particularly relevant. The basic approach for selecting information in the context of an information explosion should be the principle of sufficiency, i.e. information should be no more and no less, it should be enough to make a decision. After all, excessive information leads to informational noise and the risk of making the wrong decision. The correct and accurate formulation of the problem is the first and necessary stage of any system research. An important methodological issue is the need to identify the following relationships: a tool for realizing the goal, when it is most effective, what is the cost of its implementation and profitability, and the last question is the reverse return from this tool.

The emerging problems are usually distinguished by the degree of their structuring: by clarity, by the awareness of their formulation, by the degree of their specification and specification, by the ratio of quantitative and qualitative factors. Considering this, there are three classes of problems: well-structured and quantitatively structured, poorly structured or mixed problems, unstructured or qualitative problems.

And the last methodological problem is how to determine the criteria and indicators for achieving the goal, whether it is necessary to have a standard approach to determining the fulfillment of the goal or to take into account possible changes during the period of the fulfillment of the goal and correlate them to real changes that have occurred. The article proposes a 9-stage management decision making algorithm. It is shown that for poorly formalized tasks an effective tool is the method of qualitative modeling of complex organizational structures.
Forecasting Realized Volatility of Russian stocks using Google Trends and Implied Volatility
Authors: Bazhenov T. , Fantazzini D.
Published: April 2019

This work proposes to forecast the Realized Volatility (RV) and the Value-at-Risk (VaR) of the most liquid Russian stocks using GARCH, ARFIMA and HAR models, including both the implied volatility computed from options prices and Google Trends data. The in-sample analysis showed that only the implied volatility had a significant effect on the realized volatility across most stocks and estimated models, whereas Google Trends did not have any significant effect. The outof-sample analysis highlighted that models including the implied volatility improved their forecasting performances, whereas models including internet search activity worsened their performances in several cases. Moreover, simple HAR and ARFIMA models without additional regressors often reported the best forecasts for the daily realized volatility and for the daily Value-at-Risk at the 1 % probability level, thus showing that efficiency gains more than compensate any possible model misspecifications and parameters biases. Our empirical evidence shows that, in the case of Russian stocks, Google Trends does not capture any additional information already included in the implied volatility.
The use of fuzzy cognitive maps in the development of an experimental model of automation of production accounting of material flows
Authors: Alpeeva E. A. , Volkova I. I.
Published: April 2019

Automation of enterprise management on the basis of economic and mathematical models, information technology is one of the main stages of development for all enterprises. The use of cognitive modeling allows making management decisions under uncertainty. The article considers the construction of an experimental model of automation of production accounting of material flows based on the use of fuzzy cognitive maps. The algorithm of cognitive modeling is presented. The main advantages of cognitive tools are noted: 1) the ability to study the fine structure of management decisions (the necessary sequence of management actions, the necessary degree of activity of these actions, the study of the dynamic stability of strategies, etc.); 2) the opportunity to explore the dynamics of management decisions at a qualitative level, without attracting for this purpose hard-to-access and not always reliable quantitative information, which is extremely important in a rapidly changing business environment and the growing pace of technological innovation.

It is emphasized that none of the known management support tools has the above capabilities. Cognitive dynamic analysis significantly expands the tool base of management, based today mainly on the means of static situational analysis and prescription schemes of decision-making.

In the construction of the experimental model, the target factors of the cognitive map are determined, the connectivity analysis is carried out and the process of propagation of disturbances on the graph is studied.

The analysis showed that the proposed model is quite efficient and can be used to predict economic activity and determine the expected values of a number of parameters that need to be monitored to diagnose trends in the development of an industrial enterprise.

SSR and SRAP markers were employed to assess the genetic diversity and structure of sixty-four samples from four populations of Emmenopterys henryi. Twelve pairs of SRAP primers generated 86 bands, and polymorphism rate was 88.37%. 148 polymorphic alleles were detected by 10 pairs of SSR primers, with an average number of polymorphic alleles per primer pair of 14.8. The rank of population genetic diversity based on SRAP markers was: HS ＞DWS＞ JGS＞ WYS population, while the sortation was DWS ＞WYS＞ JGS＞ HS population. The analyzed samples based on SRAP markers were divided into two clusters by genetic structure, cluster and PCA analysis. However, the result of genetic structure, cluster and PCA analysis based on SSR markers were divided to three groups. It seemed that the extant of genetic pattern of E.henryi might have mainly attributed to its long evolutionary history, wide-ranging distribution, outcross mating system and human activities. AMOVA revealed that genetic variation mainly existed within populations. It suggested that gene exchange occurred among populations in the past, but at the same time, it resisted genetic differentiation due to gene drift. Based on the conservation of germplasm resources and genetic diversity, the combination of SRAP and SSR markers could fully implement conservation and sustainable exploitation of the endangered plant E.henryi.

Examination Of Problematic Internet Use In Information Technology Department Students In Terms Of Different Variables (Malatya Sample)
Authors: Bahçeci Ferhat
Published: April 2019

The main aim of this study is to describe the level of problematic internet use for students in Malatya who study in the field of information technology in the vocational secondary education institutions. In this study, general screening method was used. Online Cognition Scale (OCS) and the questionnaire involving demographic information form were used as data collection tools. The universe of the study consists of all information technology students (N = 482) at the vocational and secondary level in Malatya. As data analysis tool, 36-item Online Cognition Scale with seven-point Likert scale and demographic form developed by researchers were used. Cronbach's alpha (a) internal consistency coefficient of the scale was found to be 0.91. In this study, 312 volunteer students selected in the universe were surveyed and the data of 310 individuals who were understood to fill the questionnaire correctly were included in the analysis. Of the 310 individuals involved in the survey, 131 (42.2%) were found to be problematic internet users. This rate shows that a significant number of students who make up the working group are problematic internet users.  One-way ANOVA and t-test were performed separately to data of all groups and the data obtained from the problematic internet user group. Whether use of the internet is affected by different variables such as gender, age, registering to social network, attitudes towards occupational fields, and having internet at home or not was investigated according to data obtained. As a result of analyses, it was determined that while there was no relationship between daily internet usage time and problematic internet use, there was a significant relationship between both groups in terms of social network and problematic internet use. It was concluded that gender did not have any contribution to problematic internet use.

Published: April 2019

Основными факторами развития российского агропрома, как и любого производства, являются физический капитал и труд. Физический капитал охватывает природные ресурсы, финансовые активы и воспроизводимые материально-технические активы. а труд, соответственно, – однородный (чистый) труд и социально-гуманитарный, в иной терминологии, человеческий – в виде естественно-природных и благоприобретенных способностей к созиданию, – и социальный капитал, а также совокупность экономико-производственных отношений и условий, мотивирующих эффективное использование способностей.
Совершенствование системы государственного регулирования малым предпринимательством в условиях доминирования теневой экономической деятельности
Authors: Буров Виталий Юрьевич
Published: April 2019

Многие представители всех уровней власти, практики и ученые подчеркивают, что именно малое предпринимательство (МП) является важным стратегическим ресурсом развития экономики современной России. И это неоднократно подчеркивал в своих выступлениях президент РФ В. В. Путин. В частности, новый «майский указ» Президента Российской Федерации В. Путина «О национальных целях и стратегических задачах развития Российской Федерации на период до 2024 года» № 204 от 07 мая 2018 г. ставит задачи по увеличению вклада сектора МП в Валовом Внутреннем Продукте страны и доведения рабочих мест в экономики страны до 25 млн.
Уровень развитие сектора МП во многом зависит от эффективности государственного регулирования, что подразумевает создание социально-экономических и правовых условий функционирования малого бизнеса как части социально-экономической политики государства.
Уровень коррупции в России на фоне зарубежных стран
Authors: Федотов Дмитрий Юрьевич
Published: April 2019

В статье проведено исследование уровня коррупции в России и в зарубежных странах мира. В качестве источника информации использован Индекс восприятия коррупции (Corruption Perception Index), ежегодно составляемый неправительственной международной организацией Transparency International, а также данные Всемирного банка. Рассмотрены мнения различных авторов о причинах и размерах коррупции в различных странах мира. Сделан вывод о том, что коррупция наблюдается в той или иной степени во всех странах мира, как в развитых, так и в развивающих. В ходе проведенного анализа было установлено, что коррупция в России находится на высоком уровне. По уровню коррупции Россия опережает большинство развивающихся стран. Высокая коррупция тормозит экономическое развитие страны. Коррупция сопровождается высокой степенью расслоения общества по уровню доходов и большими масштабами теневой экономики.

Актуальность исследования. Процессы создания и разрушения устойчивой смеси нерастворимых жидкостей широко применяются на всех стадиях жизненного цикла товарных углеводородов: от первичной промысловой обработки до глубокой переработки нефтепродуктов. Интенсификация как прямого, так и обратного процесса позволит существенного сократить габариты и металлоемкость необходимого технологического оборудования, что в свою очередь облегчит транспортировку, снизит затраты на монтаж и ремонт. Одним из наиболее прогрессивных методов повышения эффективности эмульгирования является проведение процесса в условиях воздействия механических колебаний ультразвукового диапазона частот. Цель исследования: установить влияние параметров неоднородной системы на интенсивность эмульгирования в поле действия ультразвуковых колебаний. Методы: общие принципы распространения, отражения и интерференции акустических колебаний в жидких средах, экспериментальные методы исследования акустического эмульгирования несмешивающихся жидкостей. Результаты. Рассмотрен механизм создания эмульсии в условиях интерференции двух встречных волн ультразвукового диапазона на границу контакта исходных жидкостей. Установлено, что наибольшая эффективность диспергирования наблюдается при резонансном воздействии. Аналитическим путем определена зависимость интенсивности воздействия механических колебаний на произвольную точку системы, образованной двумя несмешивающимися жидкостями, при распространении ультразвука в нормальном по отношению к границе раздела фаз направлении. Сопоставление результатов аналитических и экспериментальных исследований показало, что расхождение полученных данных составляет менее 10 %, что позволяет, с достаточной степенью точности, применять описанную методику расчета для оптимизации конструкций устройств для эмульгирования неоднородных смесей.
