Authors: Zhu Xiaonan , Li Baokun , Wang Tonghui , Gupta Arjun K. 
Published: April 2019

Abstract
The sample mean and sample variance are commonly used statistics in our study.
In this paper, distributions of the sample mean and sample variance from a skew normal population are derived under closed skew normal (CSN) settings.
The noncentral closed skew chi-square distribution is defined, and the distribution of quadratic forms is discussed.
Our results generalize the corresponding results given under skew normal settings.
Several examples are given for illustration of our results.
Two-sided altruism as a motive for intergenerational transfer
Authors: Fujiu Hiroshi , Yano Makoto 
Published: April 2019

Abstract
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.
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.
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. The results of the work should be considered as a solution to a number of management tasks.

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.

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.
On the relationship between cognitive ability and field of study
Authors: Deldoost Mostafa H , Mohammadzadeh Parviz , Akbari Akram , Saeedi Mohammad Taghi 
Published: April 2019

The present study was conducted to investigate the existence of any possible relationship between the cognitive reflection test (CRT), numeracy and academic majors. The statistical population of this study consisted of 117 freshmen studying under the faculties selected from the University of Tabriz. The generalised structural equation modelling technique was employed for data analysis. The research results indicated that CRT and numeracy had positive and significant effects on high school and university program selection. According to the research model and the higher CRT scores of engineering and medicine (two popular majors) than that of other majors, it appears that individuals with higher CRT and numeracy scores are more inclined to get accepted into these programs. Moreover, the relationship between CRT and numeracy was positive and significant, where CRT acted as the cause and numeracy as the effect. However, the reverse need not necessarily be true.
Keywords: Cognitive reflection, numeracy skill, academic majors, relationship.

The Application of Aqueous Two-phase System in the Extraction of Natural Products from Chinese Herbal Medicine: A Review
Authors: Xiang Cheng , Chang Jie , Yue Ying Ying , Wang Ju , Fu Yan 
Published: April 2019

Background:
In the past decades, Chinese herbal medicine has attracted
worldwide attention because they contain a variety of active ingredients which are beneficial
to human health. As a result, there is a growing interest in the extraction of these substances.
However, traditional extraction methods not only need a large amount of extractant,
but are also time-consuming, moreover, the extraction efficiency is extremely poor
and tedious purification steps are required to purify the crude extract. Thus, researchers
hope to find an alternative method for the extraction of these components and the aqueous
two-phase system (ATPS) seems to be one.

Objective:
This review focuses on introducing the properties of the aqueous two-phase
system and summarizing the application of ATPS in the extraction of natural products.
Meanwhile, this review also provided a guideline to researchers who wish to design a suitable ATPS for a specific
target and how to amplify it to industrial-scale.
Aptasensing Ampicillin on Silica Substrate Gapped by Interdigitated Aluminium Electrode
Authors: Paraja Syazwan , Gopinath Subash C.B. , Md Arshad M.K. 
Published: April 2019

Background:
Ampicillin has been widely used as a broad-spectrum antibiotic for the treatment
and prevention of human diseases with a low-toxicity. Ampicillin plays an important role in
therapeutics, however, there might be some synthetically prepared compounds for the applications in
agriculture, animals and even humans that eventually have resulted in major health issues.

Objective:
This research demonstrates the approach to improve the specific in vitro detection of ampicillin
using titanium dioxide nanoparticle-based interdigitated device electrode.

Methods:
The fabrication of biosensor was performed using the conventional photolithography integrated
process of an inductively-coupled plasma dry-etching. Surface modifications were applied on a
50 µm gapped interdigitated comb-like titanium dioxide nanoparticle modified electrode surface using
0.02 M of 3-Aminopropyl trimethoxysilane, which was diluted in 75% ethanol. A Schiff-base reaction
using glutaraldehyde was followed to covalently immobilize streptavidin followed by a non-covalent
immobilization of biotinylated-aptamer DNA probe (1 µM), having a sequence of 5’-
CACGGCATGGTGGGCGTCGTG–biotin-3’.

Results:
These surface modifications with multiple self-assembling monolayers afford the additional
control for stability. The immobilized aptamer DNA probe was interacted with the target, ampicillin at 10
mg/ml, resulting in the current field changes across the device. I-V relationship interpreted the selective
binding of ampicillin and distinguished kanamycin from carbenicillin. Our sensing system was able to
detect ampicillin in a linear range of 0.1 ng until 10 mg/ml with the limit of detection at 0.1 ng/ml.

Conclusion:
This sensing platform aimed to evaluate the purity of ampicillin, a promising beneficial
approach towards the pharmaceutical industries.
Weighted Multipath Energy-Aware Clustered Stable Routing Protocol for Mobile Ad Hoc Networks
Authors: Mohindra Anubhuti , Gandhi Charu 
Published: April 2019

Background & Objective:
Mobile ad hoc networks are defined as highly dynamic, leading
to frequent disconnections and changing topologies. The energy and stability of power limited nodes
needs to be managed while designing the protocol & clustering helps in reducing the problem of
network congestion due to information overhead in large sized networks. Multipath routing helps in
balancing the load and node failures in a dynamic environment thereby helping to solve the problem
of congestion. This paper proposes a new multipath, energy-aware and stable routing protocol –
Weighted Multipath Energy-aware Clustered Stable routing protocol (WMECS).

Methods:
It uses weighted approach in clustered mobile adhoc networks. In this, both cluster head as
well as path selection is done using an optimal energy and mobility model. This helps in attaining
stable and energy efficient network with prolonged lifetime. The energy model considers energy metrics
like transmission power, drain rate and power load that helps in constructing a network with
lower energy consumption. We have also considered Gauss-Markov Mobility Model to handle the
mobility of nodes and attain a stable network with less re-clustering and re-affiliations by choosing
low relative mobility nodes in every cluster. Multipath selection is done based on a weighted metric
that considers energy and mobility coefficients whereas Optimal Paths are selected on the basis of
lower weight.

Results:
Simulation results show that the proposed protocol has better performance when compared
with other related protocols in terms of Energy Consumption, Network Lifetime and end to end delay.
