Although recent work in decision-based design (DBD) recognizes the need for an enterprise perspective in which the expected profit is the primary driver of utility, for the overwhelming majority of contributions in the DBD literature, the emphasis in the problem formulation is exclusively on the design artifact. This formulation of DBD problems is too narrow in scope, because the use of resources during the design and development phase is overlooked, making it impossible to consider the tradeoffs between the quality of the design artifact and the cost of the design process. We aim to establish a new DBD perspective that more accurately represents the tradeoffs under consideration in an enterprise context by studying the design actions with decision analysis. As a first step toward establishing this new perspective, a simple example problem of material selection for a pressure vessel is introduced and analyzed in this paper. Although several simplifying assumptions are made, the intent of this work is to qualitatively explore the impact of relaxing some of the assumptions implicitly made in previous work in DBD, specifically the assumption of ignoring the costs of the design phase and the assumption that the value of a particular analysis is independent of the ability to gain additional information from subsequent analyses. This work confirms that an analysis is worth performing only when the cost is low, the quality is high, and the overlap in the predicted utility of the two concepts is significant. These insights are also compared with the related work in information economics. We show that the decision analysis of design process decisions provides a more comprehensive model of the problem when multiple information sources can sequentially be used.

The Impact

Although recent work in Decision-Based Design (DBD) recognizes the need for an enterprise perspective in which the expected net revenue is the primary driver of utility, for the overwhelming majority of contributions in the DBD literature, the emphasis in the problem formulation is exclusively on the design artifact. This formulation of DBD problems is too narrow in scope, in that the use of resources during the design and development phase is overlooked. This omission makes it impossible to consider tradeoffs between the design artifact and the design process. In this paper, we reformulate the DBD problem in terms of the design process rather than the artifact. This new formulation more accurately represents the tradeoffs under consideration in an enterprise context and simplifies to the traditional DBD formulation if design phase resource use is assumed to be negligible. As a first step towards establishing this new formulation, a simple example problem is introduced and solved. The example involves a choice between two concepts, with an option to perform an analysis to reduce the uncertainty. Although several simplifying assumptions are made in this work that are not likely to apply in practical design problems, the intent of this work is to qualitatively explore the impact of relaxing some of the assumptions made implicitly in previous work in DBD. These assumptions include ignoring the costs of the design phase as well as the assumption that the value of a particular information source is independent of the ability to gain additional information from subsequent analyses. Solving the design process decision problem in this manner confirms the intuition that an analysis is worth performing only when the cost is low, the quality is high, and there is significant overlap in the predicted utility of the two concepts. In addition, this new DBD formulation is compared to related work in information economics, and we show that the new DBD formulation provides a more comprehensive model of the problem when a sequence of information sources is available.

Abstract The aim of this study was to investigate selective phenotyping to maintain adequate prediction accuracy. A simulation was conducted, with 10 replicates, using QMSim to mimic the structure and size of a Braford population. A population with 50 generations, 500 animals per generation, was created with phenotyping and genotyping beginning in generation 11. The scenarios investigated were: 1) Randomly phenotype and genotype 10, 25, 50, 75, and 100% of individuals each generation and; 2) Randomly phenotype and genotype 10, 25, 50, 75, and 100% of individuals in every-other generation. Estimated breeding values (EBV) were obtained using single-step GBLUP and accuracy was determined as the correlation between true BV from simulation and those estimated from the blupf90 family of programs. For scenarios where phenotyping and genotyping occurred every generation, EBV accuracies in generation 11 and 50 ranged from 0.32 to 0.32, 0.42 to 0.43, 0.49 to 0.51, 0.53 to 0.56 and 0.57 to 0.59 when 10, 25, 50, 75, and 100% of animals were chosen, respectively. The highest accuracies were 0.40 and 0.50 in generation 38 for scenarios 10 and 25%; 0.56, 0.61 and 0.64 in generation 40 for scenarios 50, 75 and 100%, respectively. When animals were selected every-other generation, EBV accuracy in generation 11 and 50 ranged from 0.24 to 0.26, 0.36 to 0.36, 0.43 to 0.42, 0.48 to 0.44 and 0.53 to 0.48 for 10, 25, 50, 75 and 100% of selected animals, respectively. The highest accuracies were in generation 23 for scenario 10% (0.31), in generation 37 for scenarios 25 (0.43), 50 (0.50) and 75% (0.55) and in generation 39 for 100% (0.59). Although increasing the density of phenotyped and genotyped animals increased prediction accuracy, some gains were marginal. These differences in accuracy must be contemplated in an economic framework to determine the cost-benefit of additional information.

In the bid to stay competitive, online shopping platforms often offer a variety of shipping options to meet the preferences of consumers. While faster delivery might be desirable for consumers, this may be detrimental to the environment. Limited studies have evaluated the comparative environmental impact of different shipping options offered by e-commerce platforms. To fill this gap, this study aims to conduct a comparative carbon footprint assessment of the shipping options available in Taobao, a highly popular Chinese online shopping website. The case of cross-border e-commerce is evaluated, where goods are ordered from China to Singapore as the shipment destination. Thereafter, a shipping choice preference survey is conducted to evaluate the impact of carbon labelling on consumers’ shipping preferences. From the perspective of the consumer, when offered a variety of shipping options to choose from, there is always a trade-off between the cost and the speed of delivery. Additional information on the carbon impact of different options could influence consumers’ decision-making. The shipping options from Taobao are referenced to determine the cost, speed, and carbon emission values for the scenarios presented in the survey. Out of 188 survey respondents, slightly more than half (55%) were found to be willing to compromise the speed of delivery for a less carbon-intensive alternative. Given this finding, the study advocates for carbon labelling to be introduced for e-commerce shipping options.

ABSTRACT We test the relationship between the change in a firm's cost of debt and the disclosure of a material weakness in an initial Section 404 report. We find that, on average, a firm's credit spread on its publicly traded debt marginally increases if it discloses a material weakness. We also examine the impact of monitoring by credit rating agencies and/or banks on this result and find that the result is more pronounced for firms that are not monitored. Additional analysis indicates that the effect of bank monitoring appears to be the primary driver of these monitoring results. This finding is consistent with the argument that banks are effective delegated monitors for the debt market. The results of this study suggest the need for future research, particularly to test the differential effects of monitoring on the cost of debt compared to the cost of equity.

The article analyzes the dynamics of the indicators of the merger and acquisition market in the banking sector, as well as the indicator of revocation of banking licenses. The analysis has shown the outperformance of bank decrease in relation to bank acquisition over the same period, which indicates a significant impact of license revocation on the merger and acquisition market. The article assesses the impact of the merger and acquisition market on the structure of proportional regulation in favor of banks with universal licenses. An increase in the concentration of capital is observed, especially in banks with state participation. The article investigates the methods of calculating the cost of mergers and acquisitions. The authors propose to add two more factors to the already known factors of change in earnings per share due to mergers and acquisitions: the type of license revoked by the regulator as a result of the rehabilitation and goodwill, which should be considered in the merger cost using additional coefficients. This will allow the merger cost to be more accurately determined and provide the investor with additional information for decision-making.

Formulation of the problem. Formulation of the problem. In the context of an increased level of uncertainty and variability of the organizational and economic environment, the significance and influence of various kinds of pathologies of a social nature (for example, the COVID-19 pandemic, all kinds of color revolutions, etc.), which have significant negative consequences for the functioning of society and its most important structures, has increased. The purpose of the article is to characterize the set of socio-economic factors in Uzbekistan in the context of pathological challenges and digitalization. The object of the research is the socio-economic processes of the development of the economy of Uzbekistan in the context of pathological challenges and digitalization. The methods used in the research are logical, comparative, analytical, scientific and methodological. The research hypothesis is based on the assumption that there is a dependence of the cost of restoring the ecological balance on the volume of national non-financial production assets. Presentation of the main material. The use of the latest achievements of scientific and technological progress, such as comprehensive digitalization and modeling of the most important factors and trends of social development, can resist the impact of modern negative challenges. The article analyzes and simulates some of the most important parameters of the functioning of the Uzbek economy, the results of which can be used in developing a strategy of actions in priority areas of development of the Republic of Uzbekistan. The originality and practical significance of the study lies in the fact that the author substantiates the relationship between the diseases of a modern person and unfavorable environmental conditions arising from his own fault. Conclusions of the study. Thus, as a result of the studies, it became obvious that the factors of social development and the socio-economic trends arising as a result of their action can be divided into two large groups: the first should include factors and trends of a negative nature associated with the action of all kinds of social pathologies; the second group, on the contrary, includes positive factors and trends, primarily associated with the progressive influence of scientific and technological progress, including with such an important modern direction as the all-round digitalization of society.

The processes of optimization of the production plan according to certain criteria were investigated. One of the problems is the difficulty of coordination and taking into account the impact of criteria on the optimal production plan. In practice, every company often faces tasks that require decisions that are quite complex and significantly affect the result. The choice of the best solutions is usually made by using a single numerical function - the criterion of optimality. The best solution is one that provides the maximum (or minimum) of the selected criterion. For the most part, the quality of decisions is characterized not by one but by many incomparable criteria. Therefore, it is necessary to make decisions based not on one but on many criteria. That is why the investigation and implementation of multicriteria models is an important stage in the development of modern science. The current rate of change in production is very high. To meet new needs and maintain the competitiveness each enterprise, firm, company must be able to make fast and correct decisions. Properly formed production program allows companies to meet the needs of consumers in products that are produced with the best use of resources, and get the maximum profit. Quite often there is a need to use mathematical methods to study this problem. The results obtained by solving a mathematical problem will make it possible to make optimal recommendations for certain actions. The main purpose of the company is usually to make a profit. One of the factors on which profit depends is the cost price. In view of this, an optimization model of the problem of increasing the cost price was proposed. The maximum price of manufactured products and the minimum costs for production was taken as criteria. At the same time it is impossible to ensure the maximum price and minimum production costs. Therefore, the solution was achieved by step-by-step solution of the proposed mathematical model of optimization of the production plan using the idea of the method of successive concessions, which would provide a certain price at low cost. An example shows an algorithm for solving this problem.

Intraoperative Oct

Abstract Background In recent years, great progress has been made in intraoperative imaging using optical coherence tomography (iOCT). There are now several commercially available iOCT systems that allow high-resolution imaging of all structures of the eye without interrupting surgery. This real-time visualisation can provide additional information to conventional surgical microscopy, but is relatively expensive. The aim of our study was to find out how often OCT integrated into the surgical microscope is used by trained surgeons, or to what extent they consider that iOCT is relevant for intraoperative procedures. Patients and Methods A prospective monocentric analysis was conducted of the field of application and user-friendliness of the EnFocus Ultra-Deep OCT (Leica Microsystems), a mobile device combination of surgical microscope and OCT. The use and benefit were investigated of iOCT, which was not mandatory. Standardised documentation and evaluation using a questionnaire was performed by the respective surgeon (n = 5) immediately after surgery. Results Over a period of 25 working days, 118 procedures were performed in the operating theatre equipped with the microscope-OCT combination. The iOCT was used in 24.6% of the 118 procedures performed. iOCT was regarded as crucial to the intraoperative procedure in 3 of the 29 patients. In one patient, it was possible to check graft orientation during a DMEK operation in a very opaque cornea and, in the second patient, to visualise the correct positioning of an iris diaphragm in the capsular bag. In the third patient, the risk of developing a pseudoforamen was assessed, and this led to the decision not to perform a full gliosis peel. Conclusion Experienced surgeons in a university eye hospital with a full surgical spectrum considered that intraoperative OCT was decisive for the course of surgery in only a few selected surgical situations, e.g. in case of limited corneal transparency. The impact of the use of iOCT on post-operative outcome quality still needs to be evaluated by larger prospective studies. On the basis of this survey, the cost-benefit ratio is still unclear.

Abstract. Introduction: Foods dense in micronutrients are generally more expensive than those with higher energy content. These cost-differentials may put low-income families at risk of diminished micronutrient intake. Objectives: We sought to determine differences in the cost for iron, folate, and choline in foods available for purchase in a low-income community when assessed for energy content and serving size. Methods: Sixty-nine foods listed in the menu plans provided by the United States Department of Agriculture (USDA) for low-income families were considered, in 10 domains. The cost and micronutrient content for-energy and per-serving of these foods were determined for the three micronutrients. Exact Kruskal-Wallis tests were used for comparisons of energy costs; Spearman rho tests for comparisons of micronutrient content. Ninety families were interviewed in a pediatric clinic to assess the impact of food cost on food selection. Results: Significant differences between domains were shown for energy density with both cost-for-energy (p < 0.001) and cost-per-serving (p < 0.05) comparisons. All three micronutrient contents were significantly correlated with cost-for-energy (p < 0.01). Both iron and choline contents were significantly correlated with cost-per-serving (p < 0.05). Of the 90 families, 38 (42 %) worried about food costs; 40 (44 %) had chosen foods of high caloric density in response to that fear, and 29 of 40 families experiencing both worry and making such food selection. Conclusion: Adjustments to USDA meal plans using cost-for-energy analysis showed differentials for both energy and micronutrients. These differentials were reduced using cost-per-serving analysis, but were not eliminated. A substantial proportion of low-income families are vulnerable to micronutrient deficiencies.

The size of international trade continues to extend rapidly from day to day as a result of the globalization process. This situation causes an increase in the economic activities of businesses in the trading area. One of the main objectives of the cost system applied in businesses is to be able to monitor the competitors and the changes that can be occured as a result of the developments in the sector. Thus, making cost accounting that is proper according to IAS / IFRS and tax legislation has become one of the strategic targets of the companies in most countries. In this respect, businesses should form their cost and pricing systems according to new regulations. Transfer pricing practice is usefull in setting the most proper price for goods that are subject to the transaction, in evaluating the performance of the responsibility centers of business, and in determining if the inter-departmental pricing system is consistent with targets of the business. The taxing powers of different countries and also the taxing powers of different institutions in a country did not overlap. Because of this reason, bringing new regulations to the tax system has become essential. The transfer pricing practice that has been incorporated into the Turkish Tax System is one of the these regulations. The transfer pricing practice which includes national and international transactions has been included in the Corporate Tax Law and Income Tax Law. The aim of this study is to analyse the impact of goods and services transfer that will occur between departments of businesses on the responsibility center and business performance, and also the impact of transfer pricing practice on the business performance on the basis of tax-related matters. As a result of the study, it can be said that transfer pricing practice has an impact on business performance in terms of both price and tax-related matters.
