Purpose: In this paper, we analyze the evolution of the financial information of companies in the retail trade sector to show how and how much the actual crisis has affected them.Design/methodology: In this paper, we have established the hypothesis about the particular behavior of the sector due to its specialization in the sale of basic goods and the strong position of the trade chain in the market. For the analysis we searched an example of companies from the SABI database, then we sorted the sample by size and linked theirs to per capita income and domestic consumption through a lineal regression. We looked for the economic variable than were explaining the evolution of the results of the sector better and studied the evolution of efficiency, operability, profitability or financial solvency ratios. We analyzed the statistically significant changes on the accounting ratios depending of the company size.Findings: The retail trade sector could be could be listed as counter-cyclical sector but all companies have lost profitability although the small ones have lost more and have had to reorganize their financial structure as a result of the crisis. On the contrary, the big companies have kept their high level of indebtedness and even their negative working capital. The specialization in the sale of products with a low elasticity demand-income and the power in the markets have allowed that these big companies don´t suffer important changes in their revenue and expenditure results.Research limitations/implications: This investigation describes and analyzes, with statistical techniques, the evolution of several accounting ratio of the companies of the retail and the relation with economics variables. However, a study of other financial information and the utilization of other statistical techniques could explain with more accuracy the reasons of these results.Originality/value: On very few occasions the retail sector has been analyzed through their financial statements. The actual crisis has caused a restructuration in most of the companies, specially in the indebtedness level. However, the big companies of the retail sector haven´t needed deleverage. The difference of the crisis effect between companies of different sectors and between the size of the same sector, is presented as a different approach.

Trade Sector

We append a retail trade sector to the industrial sector of an economy. The macroeconomic model is a variant of the circuit approach to monetary macroeconomics. The conclusion is that an increase in the size of the ‘unproductive’ sector, employment in the ‘productive’ sector remaining constant, leads to a rise in the price level and interest rates.

Purpose – The purpose of this paper is to discuss the application of a method for combining multiple criteria based on the transformation of numerical evaluations into probabilities of preference. It is applied to compare failure risks and to measure efficiency in the retail trade sector. Design/methodology/approach – The main conceptual aspect of the method employed is taking into account uncertainty. Its other important feature is allowing for the combination of evaluations in terms of joint probabilities. This avoids the need of assigning weights to the criteria. In the context of failure modes and effects analysis (FMEA) it provides a probabilistic derivation for priority scores. An application of FMEA to the sector of services is discussed. Another area of application investigated is the assessment of efficiency. Findings – Details of the application of the probabilistic composition in the evaluation of modes of failure and in the comparison of operational efficiencies of retail stores are evidenced. Research limitations/implications – The study is limited to the retail market. Other factors might be considered in the reliability analysis and other inputs and outputs might be added to the productivity evaluation. The extension of the study to other cases and sectors is straightforward. Practical implications – Features of the evaluation of modes of failure and of productivity in the retail sector are revealed. Originality/value – The main contribution of this paper is showing how to use a probabilistic framework to measure efficiency in services management.

SummaryThis study investigated the difference of [Ca2+]i movement in platelets in response to thrombin and TRAP. The involvement of αIIbβ3 in this signaling was also studied. Stimulation of platelets with thrombin at 0.03 U/ml caused platelet aggregation and a two-peak increase in [Ca2+]i. The second peak of [Ca2+]i, but not the first peak was abolished by the inhibition of platelet aggregation with αIIbβ3 antagonists or by scavenging endogenous ADP with apyrase. A cyclooxygenase inhibitor, aspirin, and a TXA2 receptor antagonist, BM13505, also abolished the second peak of [Ca2+]i but not the first peak, although these regents did not inhibit aggregation. Under the same assay conditions, measurement of TXB2 demonstrated that αIIbβ3 antagonists and aspirin almost completely inhibited the production of TXB2. In contrast to thrombin-stimulation, TRAP caused only a single peak of [Ca2+]i even in the presence of platelet aggregation, and a high level of [Ca2+]i increase was needed for the induction of platelet aggregation. The inhibition of aggregation with αIIbβ3 antagonists had no effect on [Ca2+]i change and TXB2 production induced by TRAP. Inhibition studies using anti-GPIb antibodies suggested that GPIb may be involved in the thrombin response, but not in the TRAP. Our findings suggest that low dose thrombin causes a different [Ca2+]i response and TXA2 producing signal from TRAP. Endogenous ADP release and fibrinogen binding to αIIbβ3 are responsible for the synthesis of TXA2 which results in the induction of the second peak of [Ca2+]i in low thrombin- but not TRAP-stimulated platelets.

The negative and persistent impact of the human factor on the statistics of aviation accidents and serious incidents makes proactive studies of the attitude of “front line” aviation operators (air traffic controllers, flight crewmembers) to dangerous actions or professional conditions as a key component of the current paradigm of ICAO safety concept. This “attitude” is determined through the indicators of the influence of the human factor on decision-making, which also include the systems of preferences of air traffic controllers on the indicators and characteristics of professional activity, illustrating both the individual perception of potential risks and dangers, and the peculiarities of generalized group thinking that have developed in a particular society. Preference systems are an ordered (ranked) series of n = 21 errors: from the most dangerous to the least dangerous and characterize only the danger preference of one error over another. The degree of this preference is determined only by the difference in the ranks of the errors and does not answer the question of how much time one error is more dangerous in relation to another. The differential method for identifying the comparative danger of errors, as well as the multistep technology for identifying and filtering out marginal opinions were applied. From the initial sample of m = 37 professional air traffic controllers, two subgroups mB=20 and mG=7 people were identified with statisti-cally significant at a high level of significance within the group consistency of opinions a = 1%. Nonpara-metric optimization of the corresponding group preference systems resulted in Kemeny’s medians, in which the related (middle) ranks were missing. Based on these medians, weighted coefficients of error hazards were determined by the mathematical prioritization method. It is substantiated that with the ac-cepted accuracy of calculations, the results obtained at the second iteration of this method are more ac-ceptable. The values of the error hazard coefficients, together with their ranks established in the preference systems, allow a more complete quantitative and qualitative analysis of the attitude of both individual air traffic controllers and their professional groups to hazardous actions or conditions.

The light industry is an important inter-sectoral segment and a chain of individual production areas. The purpose of the article is to carry out a comparative assessment of the cross-sectoral linkages of light industry of Ukraine with some EU countries and to prepare relevant analytical conclusions. The research revealed that the largest consumers of light industry products in 2013-2017 in Ukraine were the industries that belonged to this type of industrial activity (textile, clothing, leather and other materials), as well as the trade, furniture industry, public administration, and defense. The key problem for the functioning of the Ukrainian light industry is its high import dependence. In particular, the share of imports in intermediate consumption of light industry of Ukraine in 2017 was almost 60%. The share of imports in the expenditures of the Ukrainian light industry was almost 49%. The production activities of light industry in Ukraine use products of many ECs, but the main suppliers of raw materials and components are: textile production, production of clothing, leather, and other materials; production of chemicals and chemical products; wholesale and retail trade; supply of electricity, gas, steam, and air conditioning. In 2017, these four sectors totaled 70.74%. The following types of industrial activity in Ukraine have a significant potential for increasing output: production of rubber and plastic products; production of motor vehicles, trailers and semi-trailers; production of other vehicles; public administration and defense; compulsory social security; health care and social assistance. The further development and improvement of the technological level of Ukrainian light industry products requires greater integration of the latter with the trade sector. However, the trade sector in Ukraine requires a thorough “unshadowing”, i.e. legalization of all operations.

A methodology for scalable and concurrent real-time implementation of highly recurrent algorithms is presented and experimentally validated using the AWS-FPGA. This paper presents a parallel implementation of a KNN algorithm focused on the m-QAM demodulators using high-level synthesis for fast prototyping, parameterization, and scalability of the design. The proposed design shows the successful implementation of the KNN algorithm for interchannel interference mitigation in a 3 × 16 Gbaud 16-QAM Nyquist WDM system. Additionally, we present a modified version of the KNN algorithm in which comparisons among data symbols are reduced by identifying the closest neighbor using the rule of the 8-connected clusters used for image processing. Real-time implementation of the modified KNN on a Xilinx Virtex UltraScale+ VU9P AWS-FPGA board was compared with the results obtained in previous work using the same data from the same experimental setup but offline DSP using Matlab. The results show that the difference is negligible below FEC limit. Additionally, the modified KNN shows a reduction of operations from 43 percent to 75 percent, depending on the symbol’s position in the constellation, achieving a reduction 47.25% reduction in total computational time for 100 K input symbols processed on 20 parallel cores compared to the KNN algorithm.

Nowadays, E-learning system has been widely applied to practical teaching. It was favored by people for its characterized course arrangement and flexible learning schedule. However, the system does have some problems in the process of application such as the functions of single software are not diversified enough to satisfy the requirements in teaching completely. In order to cater more applications in the teaching process, it is necessary to integrate functions from different systems. But the difference in developing techniques and the inflexibility in design makes it difficult to implement. The major reason of these problems is the lack of fine software architecture. In this article, we build domain model and component model of E-learning system and components integration method on the basis of WebService. And we proposed an abstract framework of E-learning which could express the semantic relationship among components and realize high level reusable on the basis of informationized teaching mode. On this foundation, we form an E-learning oriented layering software architecture contain component library layer, application framework layer and application layer. Moreover, the system contains layer division multiplexing and was not built upon developing language and tools. Under the help of the software architecture, we could build characterized E-learning system flexibly like building blocks through framework selection, component assembling and replacement. In addition, we exemplify how to build concrete E-learning system on the basis of this software architecture.

Barcodes and barcode scanners transformed the grocery industry in the 1970s. I use store-level data from the 1972, 1977, and 1982 Census of Retail Trade, matched to data on store scanner installations, to estimate scanners' effect on labor productivity. I find that scanners increased a store's labor productivity, on average, by approximately 4.5 percent in the first few years. The effect was larger in stores carrying more packaged products, consistent with the presence of network externalities. Short-run gains were small relative to fixed costs, suggesting that the impediment to widespread adoption of the new technology was profitability, not coordination problems. (JEL J24, L24, L81, O33)
