Implicit Compliments in Jordanian Arabic
Authors: Al-Bataineh Hussein
Published: May 2019

This thesis is a sociopragmatic study of the speech act of implicit complimenting among Jordanian people. The researcher follows the ethnomethodological approach in order to identify the construction and organization of such a speech act. Such an approach renders the speech act of implicit compliment as an undivided, integral part of the discourse in which it occurs. Adopting this orientation enables the researcher to focus on the motives behind choosing an implicit compliment instead of an explicit one at a specific time of the discourse. The results of the study show that implicit compliments are different from explicit ones and that such a speech act belongs to a different category. The study also shows that implicit compliments convey many interactional functions that serve the speaker and the addressee and that some functions serve them both. Concerning the responses to implicit compliments, the study shows that implicit compliments have responses different from explicit ones. The study concludes with the claim that implicit compliments are similar to other speech acts and should be studied away from the theory of face to reach different findings related to the context of the speech event.

How Girls Generation Use Erotic Capital?
Authors: Setiawan Adib Rifqi
Published: May 2019

We didn’t work like common women's studies work on sexuality that generally focuses on sexual harassment or workplace romance to the exclusion of strategic forms of erotic capital. However, we consider women’s strategic sexual performances as a form of social influence and address the positive and negative consequences that may follow. This review highlights the occurrence and complexities of erotic capital in Girls Generation’s musical performances and modelling career, then discusses the important implications of use their erotic capital (i.e. face and leg) to influence others or gain desired ends. In so doing, the findings highlight a need for rethinking traditional conceptualizations of empowerment and initiates a new direction for feminist scholarship in this regard.
A novel multi-word paradigm for investigating semantic context effects in language production
Authors: van Scherpenberg Cornelia , Abdel Rahman Rasha , Obrig Hellmuth
Published: May 2019

Semantic context modulates precision and speed of language production. Using different experimental designs including the Picture-Word-Interference (PWI) paradigm, it has consistently been shown that categorically related distractor words (e.g., cat) inhibit retrieval of the target picture name (dog). Here we introduce a novel variant of the PWI paradigm in which we present 8 words prior to a to be named target picture. Within this set, the number of words categorically related was varied between 3 and 5, and the picture to be named was either related or unrelated to the respective category. To disentangle interacting effects of semantic context we combined different naming paradigms manipulating the number of competitors, and assessing the effect of repeated naming instances. Evaluating processing of the cohort by eye-tracking provided us with a metric of the (implicit) recognition of the semantic cohort. Results replicate the interference effect in that overall naming of pictures categorically related to the distractor set was slower compared to unrelated pictures. However, interference did not increase with increasing number of distractors. Tracking this effect across naming repetitions, we found that interference is prominent at the first naming instance of every picture only, whereby it is stable across distractor conditions, but dissipates across the experiment. Regarding eye-tracking our data show that participants fixated longer on semantically related items, indicating the identification of the lexico-semantic cohort. Our findings confirm the validity of the novel paradigm and indicate that besides interference during first exposure, repeated exposure to the semantic context may facilitate picture naming and counteract lexical interference.
Methodological Reporting Behavior, Sample Sizes, and Statistical Power in Studies of Event- Related Potentials: Barriers to Reproducibility and Replicability
Authors: Clayson Peter E , Carbine Kaylie Amanda , Baldwin Scott , Larson Michael J.
Published: May 2019

Methodological reporting guidelines for studies of event-related potentials (ERPs) were updated in Psychophysiology in 2014. These guidelines facilitate the communication of key methodological parameters (e.g., preprocessing steps). Failing to report key parameters represents a barrier to replication efforts, and difficultly with replicability increases in the presence of small sample sizes and low statistical power. We assessed whether guidelines are followed and estimated the average sample size and power in recent research. Reporting behavior, sample sizes, and statistical designs were coded for 150 randomly-sampled articles from five high-impact journals that frequently publish ERP research from 2011 to 2017. An average of 63% of guidelines were reported, and reporting behavior was similar across journals, suggesting that gaps in reporting is a shortcoming of the field rather than any specific journal. Publication of the guidelines paper had no impact on reporting behavior, suggesting that editors and peer reviewers are not enforcing these recommendations. The average sample size per group was 21. Statistical power was conservatively estimated as .72-.98 for a large effect size, .35-.73 for a medium effect, and .10-.18 for a small effect. These findings indicate that failing to report key guidelines is ubiquitous and that ERP studies are primarily powered to detect large effects. Such low power and insufficient following of reporting guidelines represent substantial barriers to replication efforts. The methodological transparency and replicability of studies can be improved by the open sharing of processing code and experimental tasks and by a priori sample size calculations to ensure adequately powered studies.
Potential impact of minimum unit pricing on advertised alcoholic beverage prices
Authors: Noel Jonathan K.
Published: May 2019

The current study sought to determine the potential effect of a minimum unit price policy on advertised prices for alcoholic beverages at an off-premise outlet. A free, weekly circular was monitored for advertised alcohol prices from July 2017 to June 2018. For each advertised price, the number of standard drinks per purchase, the price per standard drink, and the frequency of prices that would increase under a MUP policy similar to Scotland’s was determined. There was an inverse correlation between the number of standard drinks per purchase and the advertised price per standard drink for beer/malt beverages (r = -0.76, p < 0.001) and wine (r = -0.42, p < 0.001), which would be eliminated under MUP. Under MUP, 59.8% of advertised prices for beer/malt beverages would increase. Implementation of MUP may significantly impact beer and malt beverage prices in the off-premise location monitored in the study.
Building a Vegan Feminist Network in the Professionalized Digital Age of Third Wave Animal Activism
Authors: Wrenn Corey
Published: May 2019

Despite its legacy of feminist leadership and a continued female majority, the Nonhuman Animal rights movement has exhibited structural sexism across its various waves of protest. This institutionalized sexism not only inhibits women’s ability to protest safely and effectively, but also permeates the activist imagination and aggravates interpersonal violence. Even Nonhuman Animals as a feminized group are unwittingly disparaged in popular campaigns. This essay suggests that structural sexism in the Nonhuman Animal rights movement is nourished by its patriarchal organization, specifically its decision to professionalize. Twenty-first century vegan feminist activism on the margins has been able to circumvent the hegemony of professionalized power and challenge taken-for-granted bureaucratic structures. Yet, despite indications that vegan feminist activists are influencing the movement dialogue, the movement’s patriarchal norms have encouraged considerable pushback. Indeed, the patriarchal influence of professionalization has even created division between second wave and third wave vegan feminists.
Handling Pattern of Pesticides in Vegetables: A Case Study of Bhaktapur
Authors: Budhathoki Naba Raj , Acharya Pushpa Raj , Karki Dhruva
Published: May 2019

This research work explores handling practices of pesticides used in vegetables on the part of farmers in Bhaktapur. Specifically, it attempts to investigate the contribution of pesticides applicators to overall mishandling of pesticides. Data for this work were collected in 2018 from four locations of Bhaktapur. Primary data were collected from 123 vegetable farmers and direct observation of 42 vegetable farms based in the selected zones using questionnaire. Discussions with experts and pilot study with farmers were conducted to improve the questionnaire and provide factual data. Frequency distributions, Means, Chi-square tests were utilised for data analysis. The results of the study show that vegetable farmers were applying pesticides, without caring much about the others, in vegetable production. They frequently depended upon local sellers and neighbours to choose the best pesticide to apply. On average, pesticide handling practices at any point seemed inappropriate. Factors that influence farmers' handling practices include education, training and practical consciousness. The study indicated that vegetable farm women have higher level of exposure of pesticide risking a long term health impacts. The results of the study underscore the need of educational interventions for promoting safety during each step of pesticide handling and the responsibility of the farmers towards the society.
Land Readjustment for Regularization of Informal Settlements
Authors: Manandhar Robina
Published: May 2019

Regularization of informal settlements involves the process of legalization of tenure and upgrading of public services and infrastructures through land development. However, some settlement manages to get the services from formal authorities but lags legal tenure security. Legalization of tenure security is important so as to reduce their threat of eviction from formal authorities and improvement of their living standard. Various land development tools involves upgrading of public services and development of infrastructures but legalization of tenure security is left behind. Land development and legalization of tenure security both are the important components for regularization of informal settlements and recognize as formal settlements. Land readjustment is the tool or technique commonly used for the land development in Nepal. Thus this paper aims to indentify the applicability of land readjustment in regularization of informal settlement. In Nepal, there are prominent numbers of informal settlements along the river banks and also in urban core areas. Chadani tole along the Bagmati River is taken as a case study and analysis of applicability of land readjustment under the social and legal condition for regularization is carried out.

This research has adopted both desk research and case study methodology. Qualitative and quantitative data analysis is adopted in this study. The results of research reveal that public participation and long term occupancy are the social positive aspects for the application of LR in informal settlements. Lack of land registration, legal recognition and development regulations are the legal hurdles for the application of LR in informal settlements. Land registration of informal settlement has not been done in Nepal which is important aspect for application of LR. Thus land registration of Nepal should include the components of STDM for the pro poor land registration and recognition of social tenure to informal settlements. Applicability of LR is difficult due to the lack of sufficient area. So to address the issue and ascertain the rights of dwellers to live in the same area, high rise apartments can be adopted.
An Autonomist Marxist Perspective on Productive and Un-productive Academic Labour
Authors: Szadkowski Krystian
Published: May 2019

This text starts with a diagnosis of the inadequacy of the dispossession theory for the analysis of the relationship between capital involved in academic publishing and academic labour. It assumes that it is necessary to develop a Marxian theory of productive and unproductive labour within the field of higher education. For this purpose, an Autonomist Marxist perspective on productive labour is proposed, to facilitate analysis of the contemporary subsumption of academic labour under capital, and to organise resistance against it. The essence of this approach is rooted in an exposition of the two-sided perspective on Marxist categories of the critique of political economy. It is used here to approximate the concept of directly productive academic labour and to indicate its apparent limitations. The next step is to present a view on the systemic productivity of academic labour. This is the only way to address the issue of truly productive academic work in the Marxian sense, and the obstacles standing in the way to its full implementation, the key to which is the smooth functioning of capitalist measurement exercised within the field of science and higher education.
Reclaiming Indigeneity: Recent Publications at the University of Arizona Press
Authors: Boyer-Kelly Michelle Nicole
Published: May 2019

Colonial voices have often attempted to silence Indigenous voices, but contemporary publisher the University of Arizona Press is dedicated to disseminating scholarly texts that give voice to colonized peoples. The press’s fall 2017 catalogue is particularly interesting because of its dedication to Indigenous activism, publishing three texts that depict varied ways in which Indigenous communities are attempting to overcome stereotypes and colonial trauma while also reflecting upon one another, allowing for new discussions to build within academia and beyond. Native Apparitions focuses on visual sovereignty and reclaiming Indigenous identity, Sovereign Acts includes various contributions that add to political activism and explore issues of sovereignty, while Marking Indigeneity elaborates on Tongan communities, in particular, the concepts of time and space in contemporary society. Highlighting current trends within one press’s catalogue, this review discusses the authors’ expressed need to reclaim Indigenous identities, cultures, and languages separately, yet it also examines larger Indigenous concerns across multiple communities.
TECHNOLOGY IN TEACHING AND LEARNING

Published: May 2019

Christian Louis Lange once said, "Technology is a useful servant but a dangerous master." The effective use of technology in education has changed the face of education and it has created more educational opportunities. Both teachers and students have benefited from various educational technologies, teachers have learned how to integrate technology in their classrooms and students are getting more interested in learning with technology.The use of technology in education has removed educational boundaries, both students and teachers have collaborated in real time using advanced educational technologies. However we need to make sure that technology is used by teachers only to facilitate the learning process, not to replace the teachers. Extensive use of technology acts as an impediment to the systemized to the teaching-learning process.
  Recent advancements in educational technologies have yielded positive results in our education sector. New educational technology supports both the teaching and learning processes. Technology has digitized classrooms through digital learning tools like computers, ipads, smartphones, smart digital whiteboards. It has expanded course offerings, and has increased student's engagement and motivation towards learning.
 This paper deals with the problems faced by teachers while teaching English in the traditional methods. It propounds five new language games to teach syntax structures to the learners by incorporating technology.
Treatment of adult thoracolumbar spinal deformity: past, present, and future
Authors: Smith Justin S. , Shaffrey Christopher I. , Ames Christopher P. , Lenke Lawrence G.
Published: May 2019

Care of the patient with adult spinal deformity (ASD) has evolved from being primarily supportive to now having the ability to directly treat and correct the spinal pathology. The focus of this narrative literature review is to briefly summarize the history of ASD treatment, discuss the current state of the art of ASD care with focus on surgical treatment and current challenges, and conclude with a discussion of potential developments related to ASD surgery.

In the past, care for ASD was primarily based on supportive measures, including braces and assistive devices, with few options for surgical treatments that were often deemed high risk and reserved for rare situations. Advances in anesthetic and critical care, surgical techniques, and instrumentation now enable almost routine surgery for many patients with ASD. Despite the advances, there are many remaining challenges currently impacting the care of ASD patients, including increasing numbers of elderly patients with greater comorbidities, high complication and reoperation rates, and high procedure cost without clearly demonstrated cost-effectiveness based on standard criteria. In addition, there remains considerable variability across multiple aspects of ASD surgery. For example, there is currently very limited ability to provide preoperative individualized counseling regarding optimal treatment approaches (e.g., operative vs nonoperative), complication risks with surgery, durability of surgery, and likelihood of achieving individualized patient goals and satisfaction. Despite the challenges associated with the current state-of-the-art ASD treatment, surgery continues to be a primary option, as multiple reports have demonstrated the potential for surgery to significantly improve pain and disability. The future of ASD care will likely include techniques and technologies to markedly reduce complication rates, including greater use of navigation and robotics, and a shift toward individualized medicine that enables improved counseling, preoperative planning, procedure safety, and patient satisfaction.

Advances in the care of ASD patients have been remarkable over the past few decades. The current state of the art enables almost routine surgical treatment for many types of ASD that have the potential to significantly improve pain and disability. However, significant challenges remain, including high complication rates, lack of demonstrated cost-effectiveness, and limited ability to meaningfully counsel patients preoperatively on an individual basis. The future of ASD surgery will require continued improvement of predictability, safety, and sustainability.
Statistical Activities of IMF: A Factor of Global Financial Stabilization in the Post-Crisis Period
Authors: Аrtemieva І. О.
Published: May 2019

The areas of transformation of the statistical activities of the International Monetary Fund (IMF) in the post-crisis period are outlined, and their contribution in the global financial stabilization is assessed. The IMF results in detecting and eliminating information shortages by disseminating the standard methodology for statistical studies, unified principles for information collection, methods for computation and analysis of statistical indicators, harmonization and unification of the information content and dissemination methods are described.

The evolution of the three-tier statistical standard of IMF (Special Data Dissemination Standard, General Data Dissemination System and Special Data Dissemination Standard Plus) is analyzed as the global reference for disseminating economic and financial data, which simplifies access of economic experts from all over the world to timely and complete statistical information, thus helping the international community implement macroeconomic policies.

The article gives an assessment of IMF activities in collecting and disseminating statistical data about the areas where the system risk detected in time of the latest global crisis increased to the largest extent: studies devoted to cross-border and cross-sector relations, the market of bonds and derivatives, large banks and non-banking sector.

The area of IMF statistical activities related with studies of trans-border financial relations is described. The initiatives on eliminating information shortage, required to trigger global regulatory reforms and implemented by IMF in collaboration with other international organizations are highlighted.

The IMF strategy on data and statistics in the digital era, intended to improve the IMF statistical activities given the critical level of data volatility and the increasing demand for high quality data in conformity with the new priorities of supervision, is described.

The areas of further improvements in the international cooperation and elimination of statistical data shortages detected by the crisis by use of innovative methods for collection, processing and dissemination of statistical data, to produce the sets of timely, reliable and comparable indicators for non-financial and financial sector, are outlined.
The Evaluation of Investment Cooperation of Ukraine with EU Countries
Authors: Bulakh T. M. , Ivashchenko O. A. , Lytvyn O. Ye.
Published: May 2019

The article investigates and evaluates the investment cooperation of Ukraine with the EU. The volume, structure and dynamics of investment flows between Ukraine and the European Union are analyzed. The main problems of cooperation between Ukraine and the EU are formed, in particular: the volume of foreign direct investment (FDI) in Ukraine from the EU is directed mainly to those sectors of the economy where it is possible quickly to make a profit (for example, in financial activities), while investment in priority sectors of the economy of Ukraine, aimed at a long-term growth, is insufficient. In addition, during the analysis of the investment market of Ukraine problematic aspects were found, such as: the existence of a tendency to invest in offshore zones, a low differentiation of foreign investors for donor countries and a sharp imbalance in the structure of FDI in the economy of Ukraine. The political instability, unpredictability of a state power, lack of independent judiciary (abuse of courts), corporate raiding, prosecution by tax authorities, shortcomings in the implementation of laws, delays and lack of transparency in VAT refund, corruption and the low level of property rights’ protection demonstrate the inability to build long-term plans with EU member states.

Measures are proposed to improve investment cooperation between Ukraine and the EU in the context of deepening European integration processes, as follow: 1) bringing the strategy of attracting foreign investment in accordance with the needs of the country; 2) providing European investors with the necessary system support (for example, in business registration, attracting personnel); 3) creating the necessary conditions for the further implementation of the liberalization of the legal framework for the free movement of FDI in accordance with EU rules; 4) close cooperation with FDI donor countries; 5) providing conditions for improvement of technical and technological conditions of domestic enterprises; 6) production intensification on an innovative basis, etc.
Constructing a Set of Indicators for Performance Assessment in Higher Education Establishments
Authors: Shablysta L. M.
Published: May 2019

The current phase of the socio-economic development in Ukraine is marked by the transformation in the national higher education system in order to harmonize it with international standards. These standards are based on the basically new competence-oriented paradigm of the higher education, making emphasis on the quality of higher professional education. An important component of the education quality is the performance of a higher education establishment (HEE), which significance is growing given the increasing competition among HEEs and stricter requirements to the transparence and information openness of their operation. This raises the relevance of the problem related with selection of indicators for assessment of HEE performance. It is pointed out that methodical approaches to quality assessment of HEEs for official accreditation and ranking purposes, practiced in Ukraine now, include the indicators capable for only fragmented assessment of HEE results and focused on education processes. These approaches to performance assessment in HEEs cause a gap between the quality of HEE performance and the quality of education provided by them. It is found that variations between indicators of domestic and international rankings by which HEE performance is assessed occur because international rankings, in contrast to domestic ones, account only for HEE performance, including job placement of graduates or applications of R&D, whereas ways to achieve the performance are considered as a matter of HEE choice.   A theoretical and methodological approach to constructing a set of indicators of HEE performance is justified, which is based on the principle that a set of these indicators must provide as full as possible coverage of goals and operative tasks of HEEs, specified in the Law of Ukraine “Higher Education”. It is argued that the result of education process as a propriety operative task of HEE must be specific achievements of graduates, expected and measurable. A set of the indicators measuring results of education activities is proposed. A number of new indicators in addition to R&D spending are proposed for assessment of R&D in HEEs. Also, specific indicators are proposed for assessment of task completion: established international relations and performed international actions in the field of education; the increased education and cultural level of citizens.   It is concluded that assessment of HEE performance need to be made by multi-criteria set of components and be based on a system of estimates.
Constructing Groupings by Use of STATISTICA Software Package
Authors: Fetisov V. S.
Published: May 2019

STATISTICA software package for statistical analysis incorporates a wide range of advanced statistical methods. Quite often they are preceded by aggregating statistical survey data, which main component is their grouping. Although this phase of statistical data processing is relatively simple, the manual process of aggregation can be time-consuming given the need to process large data arrays, not mentioning a high probability of errors. Therefore, the all-purpose STATISTICA software package is a logical and reasonable tool for grouping of data.    

The article shows the grouping algorithm in STATISTICA software package, with focus on setup when constructing tables of frequencies of discrete and continual characters. Various options of grouping are scrutinized, with providing examples of their visualization.    

A large number of STATISTICA parameters offers ample opportunities for constructing user tables, but users often are not aware of these options or do not know how they can be applied. Yet, the apparently simple grouping process in STATISTICA software package can sometimes require the knowledge of fine mechanisms for its setup. The article gives a detailed description of the mechanisms for creating interval margins when applying the parameter “approximate number of intervals”.

The standard algorithm for selection is analyzed, allowing a user to limit the number of groups in a grouping. STATISTICA allows for using a number of grouping parameters, enabling to produce more convenient results or filter them. Thus, setting the clicker for label field “Grouping” in the position “Integer Categories” (integer intervals (categories)) initiates the grouping only for integer values of a variable, by excluding the observations containing its fractional values.

When only standard parameters are used, it will be impossible to form uneven or open intervals.  This issue is out of focus in specialized literature and Internet sources. The article shows the algorithm for constructing open intervals by user-set conditions and the process of creating these conditions. This option allows for forming both closed and open intervals by solving all the problems in time of grouping. Because creating such conditions is time consuming, they should be preserved if they are required for further use.

Setting up of STATISTICA software with missing data is analyzed. Its application will be advisable when a grouping for two or more variables is constructed. In this case, a separate sheet with a grouping is to be created in the worksheet for each variable.

How to Improve the Science and Engineering Education in Islamic Countries?
Authors: ŞEN Zekai
Published: May 2019

The evolutions of science, education and especially engineering training had different trends stating from the very root of human history. The future improvements in scientific and engineering education require extensive literature review to assess objectively the contributions of different civilizations among which Islamic education system had a unique feature in the past towards the researches in astronomy, physics, chemistry, algebra, robotics, medicine, etc. The universities are the highest educational institutions which provide every nation with enlightened individuals; promote intellectual development; advent and promote innovations and discoveries in field and laboratory. Prior to all these activities, it is necessary that the same universities should produce philosophical schools of thought, literature, artistic and social trends. Researchers should be able to put forward theories of good, right and beauty with ideas and orientations that serve as a reference for future policy makers in different sectors for the prosperity of the nation and humanity in general. After long centuries of slackness, the higher education is gaining momentum in the Muslim World which is striving to effect comprehensive developments in the present century. Almost in every aspects of life highly-trained manpower are required. Unfortunately, scientific philosophical thinking and logical refinement of scientific information aspects are missing in almost all the universities in Muslim countries. Especially, three T-principle as Takhayyul (imagination), Tasawwur (design, geometrical shape description) and Tafakkur (idea generation) do exist very rarely in our universities. In fact, the 3-T principle is the trigger of scientific information generation process. This paper elaborates on the education systems during the past Islamic periods, which ignited the educational system development in the western countries; its decline; and the present situation with ever increasing momentum towards the future. It is emphasized that the higher education and scientific research should have philosophy, logic, geometry and natural event visualizations prior to mathematical and computational calculations in engineering education.
Copper Indium Disulfide Quantum Dot Light Emitting Diodes for Display and Lighting Technologies
Authors: Barba Stefano
Published: May 2019

While significant advances in the development of quantum dot light emitting diodes (QLEDs) have been reported, these devices are primarily based on cadmium chalcogenide quantum dot (QD) materials. Both environmental and health concerns arise due to the toxicity of cadmium and consequently, alternative less toxic QDs must be developed for large scale QLED applications such as display and solid state lighting technologies.  In this work, copper indium disulfide (CIS) was investigated as an alternative QD material for QLED applications. Through experimentation with material synthesis and device fabrication, this project aimed to develop high performing CIS QLEDs. Several synthetic approaches were experimented with and it was determined that the injection of shorter chain 1-octanethoil as sulfur precursor with extensive shell reaction time resulted in highly luminescent QDs.  Single color QLEDs were fabricated based on typical device structure, using highly luminescent synthesized CIS QDs as the emissive layer in multilayer devices. Varying the shell reaction time of QDs in order to vary shell thickness resulted in significant differences in device performance. Using thicker shell QDs, high performing devices were obtained with the best performing QLEDs displaying a high peak current efficiency of 14.7 cd/A and high external quantum efficiency of 5.2%.

Absorption rate as a system risk measurement tool: evidence from the Viet Nam stock market
Authors: Van Thu Ngo
Published: May 2019

System risk is one of the problems concerned by many stock market researchers. Many different indicators have been used: the average price index Passcher, Laspeyres or Fisher. These indicators reflect the average price of stocks or a basket of representative stocks in the m arket. The models predicting the prices of these indexes are the measure of market risk. Recently, especially after the major financial crises, the plunge of the stock market indexes has been s een. There are two issues here: Firstly, whether a market index fully reflects systemic r isk. Secondly, any state of market risk implicit breakdowns. Mark Kritzman et al., 2010 proposed index of Absorption Rate as a system risk measurement tool. Research results of the authors and some other studies show that: 1. The sharp decline of the US stock market against the soaring rate of absorption; 2. Stocks devalued significantly after the rate of absorption increased and then p lummeted; 3 . Absorption rate is a leading indicator of the US housing market bubble; 4. Increased absorption rate has a system of market turmoil; 5. The time of major financial crisis coincided with a large change of this rate; 6. Absorption rate contains a large proportion of information about structural models and complex calculations of financial s pread. This article introduces and tests the use of absorption rate to analyze the volatility of the Vietnam stock market. The analysis will focus on a number of periods with different market fluctuations. Experiment uses absorption rate index for a pricing model.

Obtaining reliable and accurate crop classification and land cover map based on satellite data, in particular high resolution data, is one of the most important tasks in remote sensing. Such maps provide basic information for many other applied problems and are vital in remote sensing studies. Despite of which machine learning methods were utilized for maps obtaining: traditional (Random Forest, Support Vector Machine, Multi-layer perceptron, logistic regression) or state-of-the-art approaches (autoencoder, convolutional neural network, recurrent neural network) there is some noise (single pixels or groups and clusters of pixels that wrong classify) on such maps. There are traditional methods for noise reduction, however these methods do not take into account image semantics. Therefore, they are not effective for filtration land cover and crop classification maps based on satellite images. The most complicated task in the filtering such maps is to preserve boundaries between different agricultural fields and to remove quite big clusters of incorrect classified pixels (objects) and at the same time save small farmer fields that are right classified. Thus, in this paper we proposed new method for postprocessing crop classification map based on algorithm that takes into account each class specificity and as a result utilizes different thresholds for different classes. We proposed investigate each object in classification map independently and decision should be: “is this whole object a noise or not?”. We consider each class independent and use connected component labeling technique for discriminating objects from classification map. Further different types of conditions based on sharpness and compactness where proposed for the investigated object. Accuracy and efficiency of this method with the proposed filtration method have been tested on the independent set and using the visual comparison with the results of utilizing common filters. Also, McNemar statistical test has been conducted to prove the statistically significant gain of utilizing proposed filtration methodology compare to common voting filter

The processes of gas turbine unit two-stage intake air cooling by absorption lithium-bromide chiller as a high temperature cooling stage to the temperature of about 15 °C and by refrigerant ejector chiller as a low temperature cooling stage to the temperature of about 10 °C through utilizing the turbine exhaust gas waste heat for hour-by-hour changing ambient air temperatures and changeable heat loads on the air coolers as consequence during 10 days of July 2017 (10–12.07.2017) for climatic conditions of the south of Ukraine are analyzed. The computer programs of the firms-producers of heat exchangers were used for gas turbine unit inlet air cooling processes simulation.It is shown that at decreased heat loads on the air coolers an excessive refrigeration capacity of combined absorption-ejector chiller exceeding current heat loads is generated which can be used for covering increased heat loads on the air coolers and to reduce the refrigeration capacity of the absorption-ejector chiller. To solve this task the refrigeration capacity required for gas turbine unit inlet air cooling is compared with an excessive refrigeration capacity of the absorption-ejector chiller exceeding current heat loads summarized during 10 days.The system of gas turbine unit inlet air cooling with a booster stage of precooling air and a base two-stage cooling air to the temperature of about 10 °C by absorption-ejector chiller has been proposed. An excessive refrigeration capacity of the absorption-ejector chiller generated during decreased heat loads on the gas turbine unit inlet air coolers that is collected in the thermal accumulator is used for gas turbine unit inlet air precooling in a booster stage of air coolers during increased heat loads on the air coolers. The results of gas turbine unit inlet air cooling processes simulation proved the reduction of refrigeration capacity of the absorption-ejector chiller by about 50 % due to the use of a booster stage for precooling air at the expanse of an excessive absorption-ejector chiller refrigeration capacity served in the thermal accumulator. The conclusion has been made about the efficient use of a booster stage of gas turbine unit inlet air cooler for precooling air by using an excessive refrigeration potential of absorption-ejector chiller saved in the thermal accumulator

Determination of the location of the aircraft is one of the important tasks of navigation. The accuracy of aircraft positioning in the airspace is directly related to the safety of aviation. Modern trends in the development of aircraft positioning systems gradually increase the role of DME in the modern air navigation system, which sets certain requirements for the accuracy of navigation measurements.Measurement of DME distance is considered under the influence of additive measurement error characterized by Gaussian probability distribution with zero mathematical expectation and a certain value of dispersion. In accordance with regulative documents, DME error is considered as the sum of errors such as an error connected with signal propagation in space and airborne interagetor error. However, different regulative documents set up different requirements for the maximum permissible dispersion value.  In particular, FAA AC90-100A and ICAO DOC-9613, consider the error of on-board equipment as a function of distance between an interrogator and DME, while the RTCA DO-189 limits it to a certain value. In the general case, the components of error of signal propagation in space are the following: an error of signal arrival detection at the ground part of equipment; an error of delay of navigation signal at the ground part of DME; an error associated with the propagation of radio waves in the airspace. Computer simulation shows that error of modern DME systems is much more smaller then  associated requirements of regulative documents. An article analyzes the approaches used to estimate accuracy of DME measurements, proposes a generalized model for estimating accuracy, and analyzes the ways to improve accuracy of DME measurements. One of the effective means of DME accuracy increasing is the introduction of new forms of interrogating signal that is completely compatible with existing equipment, which, in contrast to the change of navigation signal, does not require the change of ground infrastructure
