Macroeconomic Environment

Growth factors of competitiveness are presented empirically. Conditions of competitiveness are determined by internal factors, dependent on enterprises themselves, and by a wide range of internal factors, dependent on the macroeconomic environment. Analysis of statistics concerning 2004-2011, collected as part of the author's research, leads to the conclusion that enterprises gain competitive advantage by low pricing and high quality of their products. A growing importance of quality as a factor determining enterprise competitiveness can also be noted.

Probabilistic Error

<p>Probabilistic predictions provide crucial information regarding the uncertainty of hydrological predictions, which are a key input for risk-based decision-making. However, they are often excluded from hydrological modelling applications because suitable probabilistic error models can be both challenging to construct and interpret, and the quality of results are often reliant on the objective function used to calibrate the hydrological model.</p><p>We present an open-source R-package and an online web application that achieves the following two aims. Firstly, these resources are easy-to-use and accessible, so that users need not have specialised knowledge in probabilistic modelling to apply them. Secondly, the probabilistic error model that we describe provides high-quality probabilistic predictions for a wide range of commonly-used hydrological objective functions, which it is only able to do by including a new innovation that resolves a long-standing issue relating to model assumptions that previously prevented this broad application.  </p><p>We demonstrate our methods by comparing our new probabilistic error model with an existing reference error model in an empirical case study that uses 54 perennial Australian catchments, the hydrological model GR4J, 8 common objective functions and 4 performance metrics (reliability, precision, volumetric bias and errors in the flow duration curve). The existing reference error model introduces additional flow dependencies into the residual error structure when it is used with most of the study objective functions, which in turn leads to poor-quality probabilistic predictions. In contrast, the new probabilistic error model achieves high-quality probabilistic predictions for all objective functions used in this case study.</p><p>The new probabilistic error model and the open-source software and web application aims to facilitate the adoption of probabilistic predictions in the hydrological modelling community, and to improve the quality of predictions and decisions that are made using those predictions. In particular, our methods can be used to achieve high-quality probabilistic predictions from hydrological models that are calibrated with a wide range of common objective functions.</p>

The Impact

Web Real-Time Communication (WebRTC) combines a set of standards and technologies to enable high-quality audio, video, and auxiliary data exchange in web browsers and mobile applications. It enables peer-to-peer multimedia sessions over IP networks without the need for additional plugins. The Opus codec, which is deployed as the default audio codec for speech and music streaming in WebRTC, supports a wide range of bitrates. This range of bitrates covers narrowband, wideband, and super-wideband up to fullband bandwidths. Users of IP-based telephony always demand high-quality audio. In addition to users’ expectation, their emotional state, content type, and many other psychological factors; network quality of service; and distortions introduced at the end terminals could determine their quality of experience. To measure the quality experienced by the end user for voice transmission service, the E-model standardized in the ITU-T Rec. G.107 (a narrowband version), ITU-T Rec. G.107.1 (a wideband version), and the most recent ITU-T Rec. G.107.2 extension for the super-wideband E-model can be used. In this work, we present a quality of experience model built on the E-model to measure the impact of coding and packet loss to assess the quality perceived by the end user in WebRTC speech applications. Based on the computed Mean Opinion Score, a real-time adaptive codec parameter switching mechanism is used to switch to the most optimum codec bitrate under the present network conditions. We present the evaluation results to show the effectiveness of the proposed approach when compared with the default codec configuration in WebRTC.

This research focuses on factors that influence the competitive advantage of the sustainable digital economy. Digital economy helped to speed up the exchange of information flows which, in turn, impacted on the creation the new forms of business and socio-economic interactions. Such sectors as banking and finance or hospitality and services are all influenced by the advancements of the digital economy that include sharing economy or Blockchain technology and its related applications. In this article, we show that digital economy is more sustainable due to the fact that it requires less energy sources and can itself contribute to the formation of the green economy and the acceptance of the renewable energy. All these features constitute its competitive advantage that needs to be further supported and fostered. In addition, we discuss key strategies and the development of skills to adapt to a digital economy and provide an overview of high-quality training for high-tech workers. It was assumed that in future, people would be able to easily acquire new skills through vocational training and vocational training. However, the spread of digital technologies has changed the way we work and has increased the need for high-quality training for workers in a wide range of professions. To use such technologies effectively, workers in an increasing number of sectors and professions need both general and advanced ICT skills.

В условиях серьезной конкуренции аптеки вынуждены прибегать к различным способам привлечения и удержания покупателей. Приоритетными факторами в плане воспитания и поддержания лояльности покупателей являются традиционный набор приемлемых цен, широкий ассортимент, высокое качество лекарственных средств, космецевтики и изделий медицинского назначения, а также удобное расположение аптеки и выкладка аптечных товаров. Однако сегодня это обязательные, но недостаточные атрибуты приверженности покупателей к конкретной аптеке. В данной статье рассматриваются основные элементы "искусства продаж", которые, по мнению экспертов, являются основополагающими для мотивации покупок в аптеке. In the face of serious competition, pharmacies have to resort to various means of attracting and retaining customers. Priority factors in terms of cultivating and maintaining customer loyalty are the traditional set of acceptable prices, wide range, high quality of pharmaceuticals, cosmeceuticals and medical products, as well as the convenient location of the pharmacy and the display of pharmacy products. However, today these are mandatory, but not sufficient attributes of customer commitment to a particular pharmacy. This article discusses the main elements of the "art of sales", which, according to experts, are fundamental for motivating purchases in a pharmacy.

A Charge

Coal raw material base of coking is the main factor characterizing the quality of coke. Therefore, it is very important to know technological properties and peculiarities of coals behavior in a charge during coking process for coals charge batching and coke quality control. One of the priority directions in study coals and charges is petrographic and reflectogram analysis, which enable to obtain data related to evaluation genuine (one-valued) technological properties of coals, coal blends and charges at production of coke of required quality. Using a broad material of study, including the one carried out by the authors of the article, a wide range of application of reflectogram analysis of coals, coals blends and charges in the coking production was shown. It was demonstrated also that application of the analysis enabled to exclude the problem of “twins”, to define the degree of genetic coals recoverability and coals grades or types relation in the mixtures for the coking. Based on the elaborated by the authors reflectogram criteria of charges for coking, a strategy of coals batching was proposed, which ensures production of metallurgical coke of required and high quality and safe running of coke ovens. Based on wide experimental studies of plastic-tough properties of coal charges, porosity of coke, its X-ray structure characteristics, strength and reaction ability, theoretical ideas were formed about mechanism of interaction in a charge of petrographically nonuniform coals comprising it during coking process, by using the proposed by the authors indices of coals nonuniformity. The indices of coals, comprising the charge, nonuniformity, differ by metamorphism degree (σR) and petrographic composition (σСК), explaining regularities of forming of quality of coke from the charge with participation of petrographically nonuniform coals. The package of the factors noted by the authors, revealed in the process of the study of coals, coals blends and charges, as well as quality of coke obtained from them, enabled to elaborate a complex index of charges coking ability (К.п.к.Vo), which enables to considerably simplify the mathematical model of coke quality prediction and to increase its reliability. Mathematical models of coke quality prediction were verified and implemented at several plants of Russia.

Do So

One autumn out of four, election forecasting surpasses baseball as America's national pastime. Then, everyone wants to know who will win, and everyone has a guess. Now, with the ballots carefully counted, forecasters await their awards. Below, I evaluate the quality of a wide range of 1984 presidential and congressional forecasts. The evaluation proceeds from nonscientific to scientific approaches, although this distinction is sometimes blurred. To lower the level of suspense, I should say that some forecasts turned out to be quite good. By way of conclusion, I offer a set of rules for selecting a high-quality forecasting instrument.Lucky GuessesMany popular election forecasting rules take advantage of chance, which has been working in their favor. Perhaps the most famous is the World Series forecast, which says, “If the American League wins the World Series, then the Republican presidential candidate will win.” This technique was accurate from 1952 to 1976, missed in 1980, but worked again in 1984 with the victory of the Detroit Tigers. A lesser known rule of this type, which is my personal favorite, is based on the Beaujolais wine harvest. Accordingly, “If the Beaujolais vintage looks bad, then the Republican will take the presidency.” This has held post-1960, and continues to do so with the poor 1984 crop (yielding a wine too light, with little color). There are other such rules that relate more directly to the candidates themselves and, in that sense, have more verisimilitude.

The study focus on testing the determinants of competitive advantage of dates marketing from Saudi Arabia through multi- regression model based on Porter’s diamond, which is determined the factor that affecting on competitiveness of nations in international marketing, such as factor conditions, demand conditions, related and supporting industries, and company strategy; structure; and rivalry. Our study selected the most competitive countries for Saudi Arabia in marketing dates in its markets (like Egypt, Iraq, and Tunisia). The results of study showed that the four determinants are significant and R square is high more than 95% in all equations this is agree with our assumptions, but the signs parameters of these determinants are different from our expectations specially with the quantity of production in Saudi Arabia which appear negative with the value of export of dates from KSA, that is because the consumption of dates in domestic market is high and it absorbs the high quality kind of dates, which is needed for external market. We tested also the same determinants for the competitive countries (Egypt, Iraq, and Tunisia); we found the same results, except Egypt, which have huge domestic demand that is effect on demand conditions in this country. Our study suggested more studies are needed for related and supporting industries of dates with this crop, to save data base in this field, and give more attention for quality of dates, packaging and prices for Saudi exporting of dates.

The members of ABTPé deserve recognition for the effective and prolific work they produce when the goal is scientific, with emphasis on our professional improvement. The concern about technical and scientific development and improvement of the association’s members is clearly highlighted by the high quality of our presentations. In our country of continental dimensions, we see many different approaches that we can apply to patients in a search for the best solutions for individuals affected by ankle and foot conditions. When evaluating our results, the interest and rights of patients should be considered, and therefore, we must keep in mind the need to accurately plan our routine practices. The care for these individuals should include a wide range of services that promote their psychological and social wellbeing and their working conditions. This is how we view a broader perspective that involves questions reflecting on how our actions affect individuals’ lives. This concern should also address the needs regarding our own quality of life. It thus becomes necessary to identify and focus on the factors that are worth the expenditure of our energy and to act mindfully in the pursuit of rewards for our actions. The diversity of our practice has demonstrated that we will be able to keep pace with technological development and apply it in a way that preserves the greater interest of patients. The format of this care will be very important in light of the enormous variety of disorders that affect the feet, as shown by the number of subjects addressed in this edition. Have a great reading. Act ethically, be mindful.   Jorge Mitsuo MizusakiEditor-in-Chief
