The article investigates the existing trends and prospects for the development of warehousing services in the system of production and processing of products, which allowed us to form the purpose of the research in this development. The chosen theme is quite topical, because warehousing processes are an integral part of the formation of supply logistics in modern production processes. One of the ways to reduce the cost of goods and services is the efficient use of resources. Ukrainian and foreign scientists have touched many questions concerning the development of the infrastructure component, solutions of optimization problems regarding the process of import-export of goods to the warehouse, but without determining the optimal values ​​of technological parameters of warehousing systems. The technological scheme of operation of the warehouse system of the enterprise LLC "MEGA CRISP» allows to see the whole chain of operations from the moment of arrival of the vehicle with cargo (containers and packaging) to the moment of sending the cargo (finished product) to the recipient; the necessary types of resources involved in these processes are also taken into account. Total costs were chosen as an evaluation indicator of the choice of an efficient supply channel. Relevant parameters of influence are taken into account: intensities of corresponding cargo flows, unit cost of the appropriate work and one hour of work of one worker, time of performance of an appropriate operation, quantity of the involved resources for performance of the appropriate operation and working time of the warehouse during the day. An imitation full-factor experiment was performed, based on the results of which a regression model in linear form with a non-zero coefficient was determined, in which each coefficient indicates the degree of influence of the relevant factor on the performance indicator. The results of determining the economic effect showed that "Variant 2" (increasing the number of workers) is the least expensive, and the level of costs is lower for all series of experiments compared to the basic variant - "Variant 1". The maximum difference is reached in 12217.8 hryvnias at the maximum loading of a warehouse. And when comparing the third and first variants: only at the maximum level of output flow (170 t / h), the third variant will be cheaper by 852.6 hryvnias. The highest level of positive value of the effect among the variants offered is "Variant 2", the level of savings will be 12,217.8 hryvnias per shift.

Abstract Background Behavioral performance of health professionals is essential for adequate patient care. There is little information on behavioral skills acquisition after simulation training of neonatal resuscitation. To assess the behavioral skills of fellows in neonatology before and after a simulation training program on neonatal resuscitation. Methods From March/2019 to February/2020, a prospective cohort with 12 second-year fellows in neonatology were evaluated during three training cycles (16 hours each) in manikin-based simulation of neonatal resuscitation with standardized scenarios. Each cycle lasted one month, followed by a 3-months interval. One video-recorded scenario of about 10 minutes was performed for each fellow at the beginning and at the end of each training cycle. Therefore, each fellow was recorded 6 times: before and after each one of three training cycles. Anxiety of the fellows was assessed by the Beck Anxiety Inventory applied before the first training cycle. The videos were independently analyzed in a random order by three trained facilitators using the Behavioral Assessment Tool. The behavioral performance was evaluated by repeated measures analysis of variance adjusted for anxiety and for previous experience in neonatal resuscitation. Results Fellows` overall behavioral performance improved comparing the moment before the first training and after the second training. The specific skills - communication with the team, delegation of tasks, allocation of attention, use of information, use of resources and professional posture - showed a significant improvement after the second month of training. No further gains were noted with the third training cycle. Anxiety was observed in 42% of the fellows and its presence worsened their behavioral performance. Conclusion An improvement in behavioral performance was observed comparing the moment before the first training and after the second training, without further gains after the third training. It is worth noting the important role of anxiety as a modulator of acquisition and retention of behavioral skills in health professionals in training.

Other Information

Even though they developed separately as two distinct disciplines, there is a complex relationship between accounting and econom-ics. For example: 1) accounting is a means that makes economic calculation possible; it provides the managers, the investors and lenders (current and potential), and the public in general with in-formation that aids them in assessing the profitability and the ap-propriate use of resources of a business. Although mainly histori-cal, accounting information allows them to form an expectation of future performance and hence it is useful for making economic decisions; 2) economics theorizes on the same ele-ments which ac-counting endeavors to measure; 3) the market for financial report-ing, i.e. for the financial statements and other information dis-closed periodically by companies, which is one of the products of an accounting system, is a market like that of any other good or ser-vice and it is therefore subject to the same economic analysis. Given this complex relation-ship, there are several paths an eco-nomic work on accounting could take. This author will approach his study first by acknowledging that accounting is an evolving institution, one of spontaneous forma-tion that has not yet reached, and probably will never reach, its fi-nal form. Although its form and practice has been subjected to regulation by dif-ferent governments and governmental agencies for centuries, in particular the market for fi-nancial reports of pub-lic companies, that fact does not change its spontaneous character. The author will also argue that competition is underutilized as a discovery procedure in accounting in general and in the prepara-tion of financial reports in particular. As a consequence of govern-ment intervention, better and less expensive ways of serving the consumers of financial reports have not yet been discovered under the current system. As an economist and practicing accountant, this author could be tempted to try to prescribe the form and substance of the finan-cial reports. Although admittedly economics could inform a lot about this, and the author does not deny the importance of those investigations for the marketplace of ideas, one of the main conclu-sions of this essay is that one of the tasks of competition is pre-cisely to discover the characteristics of the goods and services that best serve the consumers and hence, to discover the substance and form of the financial reports that best aid the users for their par-ticular ends. After this introduction, in the second part of this essay, the au-thor will summarize the conceptions that Friedrich A. Hayek de-veloped and that are relevant for his analysis. In the third part, an elaboration of accounting as a language is provided. In the fourth part, a brief summary of the history of accounting, since the spon-taneous emergence of the double entry bookkeeping system in me-dieval Europe until our times, will be presented, along with the origin and alleged justifications of government intervention in ac-counting. In the fifth part, the author will enumerate some of the problems presented by such intervention. In the sixth part, to con-clude this essay, a general prediction of a free market in accounting services will be presented. Financial reporting is a subset of accounting. Usually the same system fulfills several ends such as filling tax statements (tax ac-counting), tracking and allocation of cost elements to different products or services (cost accounting) and the preparation of fi-nancial reports for external users such as current and potential lenders and investors (financial accounting). In this work, the ar-guments are addressed in general to accounting and in particular to financial reporting. When names such as financial reporting, financial reports, financial accounting, external reporting and oth-ers similar are not explicitly mentioned, the arguments should be understood as applying to accounting in general.

Building cooling, heating and power generation (BCHP) is important for the sustainable energy strategy in China because of its contribution to energy conservation and the reduction of CO2 emissions. The number of BCHP or small-scaled combined cooling, heating and power generation systems that have been put to use or are in the course of construction is steadily increasing in China. However, in many cases the performance of BCHP systems is not good enough, i.e., the average real exergetic efficiency of whole system is much lower than expected and the economic effect is not satisfactory. This is a problem that perplexes designers and plant owners and need be investigated so as to increase the knowledge of optimizing the operation of BCHP systems. In this paper the performance of a typical BCHP system is investigated using thermodynamic and thermoeconomic analyses based on the simulating results of off-design operation and the solution of performance optimization of the system. With the help of a great number of real running data of the system and the master data supplied by manufacturers, a model of the system operation is developed to simulate the whole domain of operation on off-design conditions. In order to shorten computer time the operation domain is described by a set of functions obtained by curve fitting using the numerical data from the simulation. Two models of optimization, of which the objective functions are the exergetic efficiency and gross benefit of the whole BCHP system separately, are established in virtue of these fitted functions. The simulation of off-design operation and the solution of the optimization problems supply a great number of useful data that form various graphs, which are to be the references to energy conservation and economic operation of the systems. The investigation indicates that there are some differences between the optimum working conditions obtained by the two optimization models, whereas it is inevitable that the system runs with some lower efficiency and less gross benefit when working at high cooling or heating load factors. By analyzing the data some significant conclusions are obtained, which will be helpful for the BCHP industry in China.

The Relationship

The study investigates if there is a causality relationship between banking sector development and FDI inflows in Botswana. Though quite a number of authors have written on the subject, there appears to be no consensus on the directional causality between banking sector development and FDI inflows into the host country. At the moment, three dominant perspectives exist regarding the relationship between banking sector development and FDI inflows into the host country. The first perspective says that banking sector development attracts FDI inflows into the host country. The second perspective suggests that there is a positive feedback effect between banking sector development and FDI inflows whilst the third perspective maintains that there is no direct causality relationship between the two variables. The results from this study are consistent with the third perspective that says there is no direct causality relationship between banking sector development and FDI net inflows. This confirms that the long run relationship between banking sector development and FDI net inflows is an indirect one and the two set of variables affect each other indirectly through other factors in Botswana.

In order to efficient costs related with enormous production quantity, in less than a year a company should balance its resources compare to the plan so that the cost could be minimized. This research is about aggregate planning cost of a soft drink company, P.T. COCA-COLA TIRTALINA BOTTLING COMPANY East Java Unit. Cost elements of the company including: product storage cost, raw material storage cost, and direct workers cost. A specific and thorough account of available input usage is needed in order to balance production level with the company's resources, and this accounting process required an analysis model that could the amount of minimum cost in a plann ing process.The research 'purpose is to evaluate efficiency lebel of aggregate planning cost at a soft drink company, PT COCA COLA TIRTALINA BOTTLING COMPANY East Java Unit. The evaluated aggregate planning data are those three-moonth plans from the third three-moonth period of 1996 until the second three-moonth period of 1999. Based on high demands and aggregate planning cost realization the company had spent, if the accounting  output  using  linear  programming   analysis  model  is  less  (<)   than  the aggregate planning cost realization the company had spen, it could be said that PT. COCA TIRTALINA BOTTLING COMPAN'Y East Java Unit aggregate planning cost is notyet optimal (efficient).Research, results show that accounting using linear programming analysis model has less accounts compared to company's aggregate planning cost is not yet optimal (efficient). While the cause of aggregate planning cost inejfciency at a soft drink company, PT. COCA COLA TIRTALINA BOTTLING COMPANY East Java unit, are:- Jn product storage cost, this cost element is efficient enough because it is related to the company's policy   to anticipate expired products in the market possibility and to maintain product's quality.- Jn raw material storage cost, it could be said that the aggregate planning cost inefficiency main cause is this cost element because of high storage cost of cocentrate material and soda-brix. This high cost is related to the company's concentrate raw material supply by using dropping system- In direct works cost, the inefficiency cause is idle capacity happenings, especially on machine operators, they work ejfective(v only for  30 minutes in an hour working time. In this section a lot of time is wasted for preparations for supervising and for cleaning thefloor from broken glasses that always happens. Inefficiency also caused by the 21 hour working time that divided into 3 shifts, because on the third shift the way workers work are greatly influenced by their physical condition, they are exhausted, sleepy, and lacking of supervision, they work slow.

The Moment

In this contribution we derive and analyze a new numerical method for kinetic equations based on a variable transformation of the moment approximation. Classical minimum-entropy moment closures are a class of reduced models for kinetic equations that conserve many of the fundamental physical properties of solutions. However, their practical use is limited by their high computational cost, as an optimization problem has to be solved for every cell in the space-time grid. In addition, implementation of numerical solvers for these models is hampered by the fact that the optimization problems are only well-defined if the moment vectors stay within the realizable set. For the same reason, further reducing these models by, e.g., reduced-basis methods is not a simple task. Our new method overcomes these disadvantages of classical approaches. The transformation is performed on the semi-discretized level which makes them applicable to a wide range of kinetic schemes and replaces the nonlinear optimization problems by inversion of the positive-definite Hessian matrix. As a result, the new scheme gets rid of the realizability-related problems. Moreover, a discrete entropy law can be enforced by modifying the time stepping scheme. Our numerical experiments demonstrate that our new method is often several times faster than the standard optimization-based scheme.

Work, workers, and workers’ living conditions quickly became a field of interest for photographers. Already by the middle of the 19th century there were photographs showing working people. Nevertheless, the contexts in which such photographs were taken varied considerably. The first part of this article presents, in the historical perspective, the different causes and strategies involved in making these types of documents, up to the moment when photographs began to appear that had been made by workers themselves. The movement to photograph workers, which developed in the first decades of the 20th century, is recalled in the second part of the article (using the examples of the Weimar Republic and Soviet Russia). The third part is devoted to photographic projects whose purpose was to increase the productivity of, and control over, workers. Photography is presented as a scientific tool for measuring movement and as an illustration of the most effective manners of organizing work. At the end, the Digital Repository of Worker Photography is described, as an example of work on a collection of photos and the creation of a platform permitting further work, but also as a legal and methodological problem.

3 shows how in Nordic counties, prison officials provide significantly more resources, more competent administration, and higher-quality governance than is found in Latin American prisons. As a result, prisoners have few reasons to spend time, energy, and resources on providing these same goods and services. The chapter goes on to show that there are few prisoner-created organizations with relatively little influence on the everyday life of prisoners, and social norms are the predominant governance mechanism in place as small prison populations make gossip and ostracism powerful tools for punishing bad behavior. Even in the sphere of illegal drug use, prisoners do not use markets to coordinate the use of resources, relying instead on a system of sharing.

Theory Of Inquiry

While John Dewey wrote relatively little about higher education, he had a well-developed and largely unexplored conception of the university, grounded in his three- stage account of thought or inquiry as developed in Studies in Logical Theory and further developed in Logic: Theory of Inquiry. The first stage is antecedent to inquiry proper, residing in the situations of living that evoke thought. The second is inquiry proper, where data or immediate materials are subjected to systematic thought to yield judgment. The third is the moment after thought has considered its data and reached its result and brought it forth in situations of living as transformed by this new element. This final stage, is the “objective of thought” but lies outside of the context of inquiry proper. This chapter, building on the Dewey corpus, explains that conception, with close attention to university-based research, teaching, and service.
