<p style='text-indent:20px;'>We study two-sided vertical competition between a manufacturer and a supplier. The problem is formulated as a dynamic game where the supplier has more pricing power than the manufacturer. Based on the one-sided vertical competition modes with different recyclers as benchmarks, we derive optimal pricing and production decisions of manufacturer and supplier and further study the impacts of product quality on those decisions under the two-sided vertical competition mode. A key finding is that manufacturer/supplier prefers to be a follower rather than the first one to engage in recycling activities. Specifically, when the manufacturer/supplier has engaged in recycling activities, the supplier/manufacturer has an incentive to participate in recycling activities as well. We also find that high-quality remanufactured components/products can benefit manufacturer, supplier and consumers at the same time.</p>

In the case of non-durable goods there is some evidence that consumers do equate higher price products with higher quality products. These products are those that the consumer must experience personally before making a judgment on the product quality. In the case of durable goods there is less empirical evidence to support the price-quality connection. This paper develops a dynamic game model to investigate the price-quality connection in the presence of competition.<span style="mso-spacerun: yes;">&nbsp; </span>Specifically, the paper investigates whether or not the optimal pricing strategy in the case of a durable good, where consumers may collect quality information about the product as units diffuse into the market, should be a high quality-high price strategy or a high quality-low price strategy. This question is examined by means of a dynamic game model, which is an extension of the Narasimhan-Ghosh-Mendez (NGM) quality diffusion model. The paper explicitly incorporates competition into the NGM model. Price trajectories for two competing firms are derived so that profits are maximized for the two competitors. It is shown that the price trajectory for the firm using quality as a strategic lever is shown to be lower than that of the firm that was not using a quality strategy. This result strongly suggests that a firm pursuing a quality strategy should couple this strategy with a lower price than its competition and should not couple high prices with high quality in an effort to signal the product&rsquo;s superior quality to consumers.<span style="mso-spacerun: yes;">&nbsp; </span></span></span></p>

The article justifies for the need to identify and to keep track, in practice, of different groups of risks inherent in educational institutions under current conditions of pandemic and post-pandemic transformation of education under the influence of modern world uncertainty. Transformation of education functions in the epoch of digital economy changes the content and types of risks concomitant to the activities carried out by schools. Schools belong to the most conservative types of organizations. However, the environment in which schools operate is constantly changing. An educational institution, as any enterprise, has to engage in the activity aimed at risk management. Manifestation of the risk is, on the one hand, fraught with threats and damage, on the other hand, with opportunities. Assessment of possible threats and risks allows timely projection of undesirable results, creation of a system for situational response to unforeseen circumstances and, in the final analysis, formulation of a strategy for development of the university which would allow achievement of modern high quality education, its fundamentality and conformity to important topical requirements of the personality, society and state. Causes of developing risks characteristic of educational institutions are disclosed. External and internal risks characteristic of educational institutions, sources generating them and the importance of managing them are analyzed. The analysis of risks made reveals multi-varied threats and opportunities in the external and internal envi-ronment of the institution and their ability to have a significant effect on educational, organizational and financial activities of the schools.

In the world, product quality has long been one of the major instruments for ensuring the economic development of companies. Achieving high quality parameters, in turn, is an important part of the economic strategy of any success-oriented business organization. The article is aimed at developing directions for improving products of PJSC «Beer and Non-Alcoholic Plant «Radomyshl». The object of the research is the quality of beer produced by PJSC «Beer and Non-Alcoholic Plant «Radomyshl». The assessment of the quality level of the selected product in accordance with the requirements of DSTU 3888:2015 was carried out using the following groups of indicators: microbiological, organoleptic and physic-chemical. The process of assessing the product quality parameters is presented, which consists of seven consecutive stages and is carried out throughout the product life cycle. The factors under the influence of which the quality of products are formed and which may cause deviation from the specified quality parameters are analyzed and structured. The defects that appear due to these factors have been identified. The basis for improving the quality of products is primarily a thorough study of changes in demand for the business organization products. Three groups of measures are singled out, with the help of which one can achieve the desired level of product quality, namely: technological, organizational and socio-economic. A complex of priority measures to improve the quality of products of PJSC «Beer and Non-Alcoholic Plant «Radomyshl» is proposed. The element of scientific novelty is the development of an algorithm for the implementation of measures to improve the quality of products. During the implementation of measures to improve the quality, it is necessary to carry out systematic monitoring and generate reports on the implementation of the project in order to make possible an adjustment of the final result.

Abstract Specialized studies show how a fighter should physically be, not just any fighter, but the one who possesses the qualities and features of the ideal model, i.e. those elements that define the near-perfect fighter. The demands of the modern battlefield impose a high quality human potential that provides a good basis for the selection and training of fighters. Resistance to physical, climate, season and weather condition demands, to the prolonged efforts fighting requires is one of the important conditions of success. The paper presents information with particular impact in optimizing exercise capacity for future officers of the land forces, emphasizing once again the idea that a high level of motric ability is an essential objective.

The tradition of fruit dehydration in Serbia has been long and anviable. It seems that Serbian machine-building in the area of fruit processing technology has given its greatest contribution in this field. It has been one 100 years since the smoking house of Mr Stokovic, PhD was announced to be the best and the most promising plum dehydrator at the open competition organized in Topcider by the Ministry of Agriculture. It was the first real almost continual fruit dehydrator where plums were moved at certain intervals closer and closer to the source of heat. Such a concept of plum dehydration from lower to higher temperatures was held on even later in perhaps our most famous dehydrator CER. Even the smoky smell was retained but liquid fuel was used for technical purposes. For a long time, it has been a well- known fact that vacuum dehydration has many advantages. In our country there have been many attempts to make fruit dehydrator of greater capacities in which vacuum would be used. Of course, there have been many problems, both technical and technological, but today a hundred years after accepting Stojkovic?s smokehouse, it is our great honor to present to you the results of plum dehydration in a home-made vacuum condensation dehydrator. We hope that now path is widely open to high quality dehydration, and not only for that plum, but for fruit susceptible to oxidation which is the reason our food industry has not produced it so far. This is probably a farewell to the most dangerous, but for the product quality, the most necessary operation - sulphuration.

This article presents study that shows beta testing shapes software to the users’ hands so the product will fit the marketplace. MoldWizard is intended to reduce the time necessary to design complex mold tooling, such as this mold used to manufacture the plastic housings for high-quality nail guns. Depending on the complexity of a mold and its eventual use, the design process can require as many as 50 different steps, including tasks such as importing and cleaning up the CAD model of the part, adjusting its size for shrinkage, separating the core and cavity, generating mold bases, and adding sliders, inserts, and other standard components. Minco Tool & Mold uses Unigraphics to design molds like the one shown in the article for an automobile hubcap. Minco participated in the MoldWizard beta test program. A news group at the website let the test users communicate directly with each other. When beta testers had questions about how to use the program, they posted them in the news group and other testers would respond.

The article analyses the illuminations of two incunables which are housed in the monastery of St Francis at Šibenik. The front page of the incunable of John Duns Scotus’ Scriptum in quattuor libros Sententiarum Petri Lombardi (Johannes de Colonia et Johannes Manthen, Venice, 1477) is decorated with high-quality figural and phytomorphic illuminations. In the corners of the decorative frame in the upper margin are the figures of a heronand a monkey. Vertical sections of the frame are filled with flowers, leaves and berries in the colour blue, green and cyclamen pink and with numerous stylized golden burdock flowers (Arctium). The central part of the frame in the upper and lower margin is filled with dense, symmetrically placed thick leaves in the colour blue, green, purple and cyclamen pink with a stylized golden burdockflower (Arctium) appearing here and there. In the centre of the page is a crest composed of two fields separated by a horizontal line; the upper on is red and the lower one white. Two winged putti are set in the corners andthey hold red ribbons. Each wears a necklace made of red corals and classical sandals on their feet. They landscape around them is arid and there is only one tree, its bark dry, standing in it. The rocky ground with jagged edges is covered in small stones. The distinctly painted winged putti, the depiction of the landscape and the dense vegetal decoration filling the frame in the upper and lower margin demonstrate noticeable similarities with the works of Giovanni Vendramin, a prominent representative of Paduan Renaissance miniature. Thefront page of the aforementioned incunable at Šibenik can be attributed to him; he may well have been helped by his workshop and collaborators. First and foremost, it ought to be mentioned that the decorative frame on one of the opening pages (c. 4v) in an Antiphonary at Ferrara features identical type of leaf decoration as the one that fills the upper and lower margin in the incunable at Šibenik. Here too, the playful putti wear classical sandals and necklaces made of red coral. Furthermore, putti with identical physiohnomies – wearing coral necklaces and classical sandals while holding ribbons in their hands – can be found on fol. 2r in the incunable of Marcus Tullius Cicero’s Orationes (Venice, Christophorus Valdarfer, 1471, Philadelphia, The Rosenbach Museum and Library, Inc 471ci). The landscape in which the putti are depictedis also arid and marked by a single dry tree rising from the ground covered with small stones. Identical putti can be seen on the cover of the incunable of Marcus Tullius Cicero’s, Tusculanae Quaestiones (Venice, N. Jenson, 1472, London, British Library, C.1c.10, fol. 1). The landscape is also depicted in the same way. An excellent comparative example can be found in the winged putti standing on an all’antica structure on the cover of the manuscript of Jacopo Camphora’s, De immortalitate animae (London, Brittish Library, MS Add. 22325) which is decorated with architectural forms. The left and the upper margins of the opening pages of Book I and Book III of Gaius Julius Caesar’s Commentariorvm de bello Gallico (Milan, Antonius Zarotus, 1477) are decorated with frames filled with white vine scrolls on red, green and blue background with white dots. The decoration extends beyond the ornamental frames and reaches into the gold initials G and C. Although the decorative frames were not completely finished, it can be ascertained that they were made with great skill and are of high quality. This frame type was frequently used by Giovanni Vendramin and the examples from Šibenik are very close to some of his works, especially those made for Jacopo Zeno, the Bishop of Padua (Padua, Biblioteca Capitolare).

Abstract Packaging is an essential component of getting horticultural produce (fruit, vegetables or cut flowers) from the farm to the consumer. Packaging allows for the ease of handling and serves a vital role to protect and maintain product quality through the supply chain. Packaging of horticultural produce can be made of a range of products such as wood, fibreboard, jute (hessian) or plastics, where each packaging type is suitable for different applications. The best packaging type is the one that meets its purpose.

This chapter demonstrates how the introduction of large screens to contemporary public spaces function to assimilate diverse arts, commercial, and public forms into a conservative regime. On the one hand, the new opportunities that accompany the large public screens are subverted by the logic of capitalist accumulation, which informs a public address designed to achieve high volumes of individual engagement, rather than high quality public engagement. On the other hand, new opportunities to enhance public engagement are subjected to bureaucratic modes of governance, which pre-emptively censor content such that it extends and satisfies conservative regimes of early broadcast regulation. The authors argue that the confluence of capitalist and bureaucratic regimes governing big screens effectively balkanise audiences, valorise nondemocratic forms of participation, and privatise public spaces.

Nectarivorous insects generally adopt suction or lapping to extract nectar from flowers and it is believed that each species exhibits one specific feeding pattern. In recent literature, large groups of nectarivores are classified as either ‘suction feeders', imbibing nectar through their proboscis, or ‘lappers', using viscous dipping. Honeybees ( Apis mellifera ) are the well-known lappers by virtue of their hairy tongues. Surprisingly, we found that honeybees also employ active suction when feeding on nectar with low viscosity, defying their classification as lappers. Further experiments showed that suction yielded higher uptake rates when ingesting low-concentration nectar, while lapping resulted in faster uptake when ingesting nectar with higher sugar content. We found that the optimal concentration of suction mode in honeybees coincided with the one calculated for other typical suction feeders. Moreover, we found behavioural flexibility in the drinking mode: a bee is able to switch between lapping and suction when offered different nectar concentrations. Such volitional switching in bees can enhance their feeding capabilities, allowing them to efficiently exploit the variety of concentrations presented in floral nectars, enhancing their adaptability to a wide range of energy sources.
