Full textAbstract:
Purpose The purpose of this paper is to examine whether customer-company identification (CCI) can transfer from one organization to the next within the context of service alliances. Design/methodology/approach A between-subjects experiment using a fictitious alliance and a field study focused on a real alliance tests identification transfer at the time of a service alliance announcement and while the service alliance is in operation. Findings Identification transfer is enabled by an exclusive service alliance but not an inclusive one. For identification transfer to be maintained, customers must perceive the companies as a coherent group (i.e. high entitativity) and have close physical proximity to the alliance. Originality/value By drawing heavily on self-categorization theory for the proposed effects, the current research provides a new theoretical framework to the service and brand alliance literature that contrasts with the attitude-based theories commonly used. Furthermore, the current research explores how company-company relationships influence CCI whereas most research has focused on characteristics of the customer-company relationship. These two differences suggest service alliances provide more value to the companies and customers than currently realized.

Purpose. To identify the sources of error in predictability beyond the effective lens position and to develop two new thick lens equations. Methods. Retrospective observational case series with 43 eyes. Information related to the actual lens position, corneal radii measured with specular reflection and Scheimpflug-based technologies, and the characteristics of the implanted lenses (radii and thickness) were used for obtaining the fictitious indexes that better predicted the postoperative spherical equivalent (SE) when the real effective lens position (ELP) was known. These fictitious indexes were used to develop two thick lens equations that were compared with the predictability of SRK/T and Barrett Universal II. Results. The SE relative to the intended target was correlated to the difference between real ELP and the value estimated by SRK/T (ΔELP) (r = −0.47, p=0.002), but this only predicted 22% of variability in a linear regression model. The fictitious index for the specular reflection (nk) and Scheimpflug-based devices (nc) were significantly correlated with axial length. Including both indexes fitted to axial length in the prediction model with the ΔELP increased the r-square of the model up to 83% and 39%, respectively. Equations derived from these fictitious indexes reduced the mean SE in comparison to SRK/T and Barrett Universal II. Conclusions. The predictability with the trifocal IOL evaluated is not explained by an error in the ELP. An adjustment fitting the fictitious index with the axial length improves the predictability without false estimations of the ELP.

Full textAbstract:
A rigorous analytical method is developed for calculating the interaction factor between two identical piles subjected to vertical loads. Following the scheme proposed by Muki and Sternberg, the problem is formulated by decomposing the pile soil system into an extended soil mass and two fictitious piles. With the consideration of the compatibility condition that the axial strain of the fictitious pile be equal to the corresponding strain average over the extended soil, a Fredholm integral equation of the second kind governing the unknown axial forces along fictitious piles is established and then solved using numerical procedures. The real pile head settlement is subsequently calculated based on the determined fictitious pile forces and finally, the desired pile interaction factor is derived. Comparison with existing solutions confirms that the conventional interaction factor approach does tend to overestimate the interaction and may cause considerable errors for long compressible piles. Numerical results for the interaction factor between two piles in both semi-infinite and finite layered soils are presented over a wide range of pile and soil parameters, and also the settlement behaviour of a 3 × 3 pile group embedded in a semi-infinite soil is studied by virtue of the newly established interaction factor.

Full textAbstract:
The Glaser method is an assessment procedure for the risk of moisture accumulation in building mono-dimensional structures, that could be used to evaluate mould risk and interstitial condensation risk.It is based on a simplified model that does not represent the real phenomenon and its limitations are well-known qualitatively.This work provides a comparison in terms of moisture content between the Glaser method and WUFI Pro, an advanced heat, air and moisture transfer prediction tool. First the influence of material properties is evaluated on four fictitious materials walls, then six different building envelope typologies for six weather files from Central and Southern Europe are modelled to evaluate the Glaser method results.The effects of the Glaser method simplifications are quantified in terms of moisture content percentage difference.

Purpose The purpose of this paper is twofold: first, to study which perceived and attained entrepreneurial competences acquired by students while developing a business plan are rated most highly; and second, to analyse the differences observed in entrepreneurial competences, depending on whether the business plan developed is real or fictitious. Design/methodology/approach To analyse the role played by business plans in perceptions and attainment of competence, data were collected from students enrolled on a final project course of a bachelor’s degree, specifically the Bachelor’s Degree in Business Administration and Management at the Universitat Oberta de Catalunya. The course in question focussed on entrepreneurship and business plans. The data on perceived and attained competences were obtained through questionnaires and assessment rubrics, respectively. Mean comparison analyses were conducted to investigate any differences in entrepreneurial competences existing between students developing real or fictitious business plans. Findings The paper finds evidence that the process of creating a business plan results in entrepreneurial competence being highly rated and that whether the business plan is real or fictitious does not affect the level of entrepreneurial competence. Research limitations/implications A longitudinal study will be required to analyse how entrepreneurial competences evolve during the business plan creation process. Originality/value This paper finds that few studies have been conducted to explore entrepreneurial competences in relation to business plan development and shows that more complete research is required. Moreover, both perceived and achieved competences are considered, an analysis not previously carried out.

Abstract On June 9th, 2015, ACME Oil Company’s rig suffered a dynamic positioned ‘run-off’. The mobile drilling unit lost its station above the wellhead and a loss of well control was experienced. “A massive environmental emergency unfolded…affecting pristine coastline and masses of wildlife”. Incident Management and Field Response Teams were activated in a multi-agency operation, bringing together 200 personnel from 16 oil and gas companies and 18 government agencies and third party providers. Source control, aerial, offshore, nearshore, shoreline and oiled wildlife response capabilities were deployed and national/international support was utilised. Jointly managed by the Australian Marine Oil Spill Centre (AMOSC), the Australian Maritime Safety Authority (AMSA), the Federal Department of Industry and Science, and the Western Australian Department of Transport -Exercise Westwind was a successful multi-faceted marine spill response, demonstrating Australia’s collective Industry/Government capacity to respond to a large, offshore loss of well control incident in a remote and isolated location. ACME Oil Company was a fictitious company formed to enable the amalgamation of Australian petroleum companies to exercise industry arrangements under one ‘banner’ during the exercise period. ACME Oil Company had its own set of credentials, company website and Oil Pollution Emergency Plan. The company also held real time memberships with a number of service providers including AMOSC, Oil Spill Response Ltd, Trendsetter Engineering International, Oceaneering Australia and addenergy. Representing an innovative approach to spill response exercising, ACME Oil Company was a valuable and critical aspect to industry and governments participation under a non-attributable banner. Additionally, it enabled safe, widespread lessons to be observed, allowed for real-time testing of arrangements and provided a safe environment for regulators, stakeholder and industry interplay. The exercise was an efficient and practical solution for Industry titleholders and their third party supporting organisations, to test shared response resources and to ensure Industry arrangements for responding to oil pollution are in accordance with the Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2009. This paper will discuss the development program behind the exercise and the experience of managing an exercise of this nature. It will highlight the successes including the creation and implementation of a fictitious company and the extensive collaboration between the industry and government personnel involved. It will also look forward – where are we 11-months later? Can the history of exercising and/or response help us improve for the future-implementation of change and continued testing is critical in furthering our oil spill response capability and capacity.Exercise Westwind – Operational Phase TwoExercise Westwind – Operational Phase Two

A hybrid bundle adjustment is presented that allows for the integration of a generalised building model into the pose estimation of image sequences. These images are captured by an Unmanned Aerial System (UAS) equipped with a camera flying in between the buildings. The relation between the building model and the images is described by distances between the object coordinates of the tie points and building model planes. Relations are found by a simple 3D distance criterion and are modelled as fictitious observations in a Gauss-Markov adjustment. The coordinates of model vertices are part of the adjustment as directly observed unknowns which allows for changes in the model. Results of first experiments using a synthetic and a real image sequence demonstrate improvements of the image orientation in comparison to an adjustment without the building model, but also reveal limitations of the current state of the method.

Full textAbstract:
The finite element method is used to compute the ultimate bearing capacity of a fictitious strip footing resting on the surface of c-φ weightless soils and a real strip footing buried in the c-φ soils with weight. In order to compare the numerical solutions with analytical solutions, the mainly existing analytical methods are briefly introduced and analyzed. To ensure the precision, most of analytical solutions are obtained by the corresponding formulas rather than table look-up. The first example shows that for c-φ weightless soil, the ABAQUS finite element solution is almost identical to the Prandtls closed solutions. Up to date, though no closed analytical solution is obtained for strip footings buried in c-φ soils with weight, the numerical approximate solutions obtained by the finite element method should be the closest to the real solutions. Apparently, the slip surface disclosed by the finite element method looks like Meyerhofs slip surface, but there are still some differences between the two. For example, the former having an upwarping curve may be another log spiral line, which begins from the water level of footing base to ground surface rather than a straight line like the latter. And the latter is more contractive than the former. Just because these reasons, Meyerhofs ultimate bearing capacity is lower than that of the numerical solution. Comparison between analytical and numerical solutions indicates that they have relatively large gaps. Therefore, finite element method can be a feasible and reliable method for computations of ultimate bearing capacity of practical strip footings.

Background Privacy restrictions limit access to protected patient-derived health information for research purposes. Consequently, data anonymization is required to allow researchers data access for initial analysis before granting institutional review board approval. A system installed and activated at our institution enables synthetic data generation that mimics data from real electronic medical records, wherein only fictitious patients are listed. Objective This paper aimed to validate the results obtained when analyzing synthetic structured data for medical research. A comprehensive validation process concerning meaningful clinical questions and various types of data was conducted to assess the accuracy and precision of statistical estimates derived from synthetic patient data. Methods A cross-hospital project was conducted to validate results obtained from synthetic data produced for five contemporary studies on various topics. For each study, results derived from synthetic data were compared with those based on real data. In addition, repeatedly generated synthetic datasets were used to estimate the bias and stability of results obtained from synthetic data. Results This study demonstrated that results derived from synthetic data were predictive of results from real data. When the number of patients was large relative to the number of variables used, highly accurate and strongly consistent results were observed between synthetic and real data. For studies based on smaller populations that accounted for confounders and modifiers by multivariate models, predictions were of moderate accuracy, yet clear trends were correctly observed. Conclusions The use of synthetic structured data provides a close estimate to real data results and is thus a powerful tool in shaping research hypotheses and accessing estimated analyses, without risking patient privacy. Synthetic data enable broad access to data (eg, for out-of-organization researchers), and rapid, safe, and repeatable analysis of data in hospitals or other health organizations where patient privacy is a primary value.

Purpose This paper aims to analyse the legal framework of reincorporations and subsequent change of applicable law in Greece and Cyprus. A comparison between Greek Law and Cyprus Law is drawn. This paper highlights possible required reforms. Cyprus has a quite detailed legal framework of voluntary inbound and outbound reincorporations. While Greece has certain provisions on outbound reincorporations, it does not have any provisions on inbound reincorporations. The compatibility of these national provisions with internal market rules, as interpreted by the case law of the Court of Justice of the EU (CJEU), is discussed. Design/methodology/approach This paper follows a comparative approach. After a careful analysis of each national legal framework, a comparison between Greek law and Cyprus law follows. This paper also follows an EU law approach. Findings These two jurisdictions present some differences. Cyprus adopting the incorporation theory has a detailed, sophisticated and flexible legal framework of reincorporations. Although Greece adopting the real seat theory has some special provisions for outbound reincorporations, there are no specific provisions for inbound reincorporations. Inbound reincorporations are possible under Greek law, but the absence of detailed provisions is against legal certainty. Cyprus law on reincorporations could be used as an example for Greek legislature. However, possible EU harmonisation of seat transfers is expected to have an immense impact on national provisions for reincorporations. Practical implications Reincorporations constitute a significant corporate restructuring technique with important practical implications on the economy. Apart from academics, this paper attracts the interest of lawyers, managers, accountants, officers of supervisory and regulatory bodies and policymakers engaged with reincorporations. Originality/value This is one of the few academic papers comparing Greek and Cyprus company law and private international law. It is the first paper that compares the Greek and Cyprus legal framework of reincorporations.

Full textAbstract:
The authors study the transformation of non-cash money into banknotes as a cover-up for one of the economic crimes. They analyze the economic interests, motives and goals of the heads of commercial companies that transform non-cash into cash. The current taxes regime is used to compare the financial losses of the working capital of a commercial company whose head has the task of transforming non-cash money into cash. They study the criminal demand for the unaccounted cash and its supply and formulate the concept of «entrepreneurial insolvency». The authors also argue for the possibility of a total abandonment of cash in the shortest possible time. They present a critical evaluation of the criminal schemes where sham companies offer unaccounted cash and show the role of commercial banks and the Bank of Russia in counteracting such criminal business practices. The authors have also compiled an overview of research publications on this topic that include the works of Russian legal scholars and economists. At the same time, they examine the positions of authors from the USA, Kazakhstan, Italy, Ukraine, Belarus and Turkmenistan. They analyze the current Russian constitutional, civil, banking and tax legislation as well as the normative base of the social and pension insurance. It is argued that the transformation of non-cash money into cash is a real fictitious deal not named in the legislation; it is concluded between juridical persons as a cover-up for illegal actions. These actions are initiated by the head of a commercial company who is motivated by mercenary interests and carries out a criminal intent in an organized group with a prior agreement.

Company (or firm) valuation – an evaluation process of a company to appreciate the value of a company’s right in this company or business. There are two objective and subjective aspects of value. The subjective value is the value determined by individuals and desires. For example, it is a subjective decision that the investor assesses the competitor over the normal to be monopoly in the market. The objective value is the value determined by the cost and benefits of the goods and services.Although there are many performance measures that measure company success, none is as comprehensive as value. There is a strong and linear relationship between a company’s market value and its discounted cash flows. Because earnings are used to generate the income statement, they cannot be used to measure cash flows.Firm valuation means seeking the goal of the firm which is listing it on the Stock Exchange. Real value of the firm can be calculate with different methodologies. These methods are related to future expectations or background of the firm’s financial data. Discounted Cash Flow (DCF) Method is one of the firm valuation methods used all around the world and it is accepted by the experts.Market value is also used for comparison and performance measurement purposes. Valuation of a company’s future expectations, current status, mergers or acquisitions is extremely important. Even the firm value can be used to compare the capital markets of countries. In our study, capital markets and total market values of selected countries are compared. The increase in the share price increases the market value of the company. Therefore, the aim of the firms should be to increase the shareholder value or to take decisions to increase the stock price.

Full textAbstract:
The standard two-stage approach for estimating non-linear dose–response curves based on aggregated data typically excludes those studies with less than three exposure groups. We develop the one-stage method as a linear mixed model and present the main aspects of the methodology, including model specification, estimation, testing, prediction, goodness-of-fit, model comparison, and quantification of between-studies heterogeneity. Using both fictitious and real data from a published meta-analysis, we illustrated the main features of the proposed methodology and compared it to a traditional two-stage analysis. In a one-stage approach, the pooled curve and estimates of the between-studies heterogeneity are based on the whole set of studies without any exclusion. Thus, even complex curves (splines, spike at zero exposure) defined by several parameters can be estimated. We showed how the one-stage method may facilitate several applications, in particular quantification of heterogeneity over the exposure range, prediction of marginal and conditional curves, and comparison of alternative models. The one-stage method for meta-analysis of non-linear curves is implemented in the dosresmeta R package. It is particularly suited for dose–response meta-analyses of aggregated where the complexity of the research question is better addressed by including all the studies.

Full textAbstract:
The given article aims to evaluate different quantitative demand forecast methods through a case study on a glass tempering company. The analysis were held based on historical data series, which allowed the use of a part of this data for method application and another part for comparison and validation of the model`s results. The methods were compared based on obtaining the mean absolute error. In the studied company, the raw material request for the suppliers was made when new orders are ordered (pulled production). This method results in longer responsiveness, mainly due to the waiting time of raw material arrival. The application of those different demand forecasting models were analysed over three types of products on the tempered glass category, which represents a total volume of 65% of the company's costs. As a result, two methods were better adapted to the real data, providing absolute errors between 0.25 and 0.29. This given work showed that the application of the demand forecasting methods would reduce orders delivery time, what could lead to real gains to the analyzed company.

PurposeThe purpose of this paper is to document the corporate site selection and acquisition process in a Nigerian global system for mobile (GSM) communication company, using a case study approach.Design/methodology/approachThe study integrates a literature review and a case study. The researcher made use of semi‐structured interviews to obtain information about the process of site selection and acquisition from the personnel of the property management department (property managers/SAQ managers) of the studied organisation. Beside the interviews, there was a series of follow‐ups for further clarification through telephone conversation and e‐mail. On average, the interview took about 45 minutes with each respondent, aside from prior occasional discussions undertaken to obtain some data.FindingsData obtained indicated that the process of site acquisition follows the global trend of outsourcing of non‐core services by organizations to consultants who have the technical ability to handle such assignments. The case study also revealed an arrangement of successful collaboration between multinational companies and local/indigenous firms.Research limitations/implicationsThe approach is subject to data distortion as there is no yardstick for comparison in the industry.Practical implicationsThe study has major implications for real estate practice in Nigeria. Real estate practitioners need to acquire the technical ability to meet real estate/site acquisition service requirements of multinational companies. The profession also needs qualified and competent members who can compete favourably with their foreign counterparts, who have hitherto been providing site acquisition services for the foreign companies in their overseas branches.Social implicationsThe method of outsourcing breeds competitiveness for site acquisition service provision and enhances efficient service delivery. It helps indigenous contractors to favourably compete for jobs of international standard.Originality/valueThe study explores the case study approach to provide a guide for foreign investors towards meeting their real estate needs.

Full textAbstract:
The article in question describes the results of comparison of numerical and real experiments, presented in the report of the Canadian laboratory “Bodycote” [1]. The paper depicts the test fixture, on witch six samples (two typical sizes) of light gauge steel stud “ATLANT” were tested. As a result, dependencies between bearing capacity and characteristic displacements were received. In order to repeat the experiment, the series of computer models were created with the software ANSYS. The computer models have complex nature: geometrical / physical nonlinearity was used. For accounting steel material nonlinearity, we used a multilinear model with isotropic hardening (MISO). The proper diagram was used for each typical size in accordance with the experiments on the tensile-testing machine. For the purpose of supporting condition and load modeling which are identical to the full-scale experiment, a couple of contact elements were used. The utilization of contact elements allowed us to consider friction between the sample and the supporting structures. One of the disadvantages of the full-scale experiment is the absence of measurements of the initial geometrical imperfections. For their consideration the use of probabilistic approach is suggested. This approach entails calculation of several models with different spread of initial imperfections. The initial geometrical imperfections with stochastic nature were included in the computing model. Parameters of distribution were based on the measurements of eighty-eight C-shaped members [8]. In the result of comparison, fine precision in terms of the ultimate bearing capacity and deformation pattern were established. According to expectation, the results of the full-scale experiments were found inside the fictitious “corridor”, created in accordance with the results of computer modeling.

Purpose – The purpose of this paper is to analyze the moderating role of the cultural dimensions of long-term orientation (LTO) and individualism (IND) on the relationships between satisfaction online, message involvement (MI) and perceived usefulness (PU) of the web site on attitude toward the web site. Design/methodology/approach – The authors chose a between-subjects experimental design, using culture (Spanish vs British) as the independent variable. Two versions of a web site for a fictitious tourist destination were created – one written in Spanish and the other in English. The sample comprised 491 users. Findings – The findings indicate that the LTO dimension moderates the relationship between satisfaction online and PU on attitude toward the web site. The relationships between MI and attitude toward the web site could not be confirmed. Research limitations/implications – The main limitation of this study is the comparison of only two cultures, Spain vs the UK. Practical implications – The key implication is that if marketers and web site designers can better understand how national cultural differences moderate the attitude formation and change process among tourists, this will enable them to market their destinations and services more effectively. National cultural differences explain the differences found in the effect of satisfaction and PU on attitude toward the web site. Originality/value – This study is one of the few analyzing the moderating effect of LTO and IND on three antecedents of attitude toward the web site. The original cultural values established by Hofstede (2001) were tested among the present sample to establish the extent to which they remain true today. To create an authentic browsing scenario for the experiment, a web site was specially designed for a fictitious tourist destination, with its own domain name (buyada.org). Subjects were invited to browse the site freely while carrying out the task assigned to them. This approach contributed added value to the research by simulating the real behavior of tourists who are faced with a range of choices when putting together a tourism package for a given destination.

Full textAbstract:
The purpose of this paper is to present an inventory balance model including an order-up-to replenishment policy with partial backlogging. Pictured in the model is a situation, where goods are not replenished continuously, but only at predetermined intervals. The model is described by ordinary differential equations with delayed argument because of the assumption of a time lag between ordering and delivery.A computer simulation which helps to demonstrate and verify model behaviour is utilized for the numerical solution of the model. Sales data of a real company are used as the input data.Due to the comparison of the designed model outputs against the real state in the company, it was verified that it is possible to achieve a substantial reduction in warehousing costs without a disproportionate increase in the risk of inventory shortage. The authors note that modern methods of functional analysis can be successfully applied in solving an inventory balance model.

Purpose This study aims to propose a new genetic algorithm for solving supply chain scheduling and routing problem in a multi-site manufacturing system. The main research question is: How is the production and transportation scheduled in a multi-site manufacturer? Also the sub-questions are: How is the order assigned to the suppliers? What is the production sequence of the assigned orders to a supplier? How is the order assignment to the vehicles? What are the vehicles routes to convey the orders from the suppliers to the manufacturing centers? The authors’ contributions in this paper are: integration of production scheduling and vehicle routing in multi-site manufacturing supply chain and proposing a new genetic algorithm inspired from the role model concept in sociology. Design/methodology/approach Considering shared transportation system in production scheduling of a multi-site manufacturer is investigated in this paper. Initially, a mathematical model for the problem is presented. Afterwards, a new genetic algorithm based on the reference group concept in sociology, named Reference Group Genetic Algorithm (RGGA) is introduced for solving the problem. The comparison between RGGA and a developed algorithm of literature closest problem, demonstrates a better performance of RGGA. This comparison is drawn based on many test problems. Moreover, the superiority of RGGA is certificated by comparing it to the optimum solution in the small size problems. Finally, the authors use real data collected from a drug manufacturer in Iran to test the performance of the algorithm. The results show the better performance of RGGA in comparison with obtained outputs from the real case. Findings The authors presented the mathematical model of the problem and introduced a new genetic algorithm based on the “reference group” concept in sociology. Robert K. Merton is a sociologist who presented the concept of reference groups in society. He believed that some people in each society such as heroes or entertainment artists affect other people. The proposed algorithm uses the reference group concept to the genetic algorithm, namely, RGGA. The comparison of the proposed algorithm with DGA and the optimum solution shows the superiority of RGGA. Finally, the authors implement the algorithm in a real case of drug manufacturing and the results show that the authors’ algorithm gives better outputs than obtained outputs from the real case. Originality/value One of the major objectives of supply chains is to create a competitive advantage for the final product. This intension is only achieved when each and every element of the supply chain considers customers’ needs in every function of theirs. This paper studies scheduling in the supply chain of a multi-site manufacturing system. It is assumed that some suppliers produce raw material or initial parts and convey them by a fleet of vehicles to a multi-site manufacturer.

Full textAbstract:
The financialization genesis of the global economy centered in the United States is on the bifurcation point now— a fictive capital’ expansion is damaging with the social capital regeneration mechanism disaster. The method of identifying and estimating the fictive capital’ extension is absent for now. The fictive capital exists as a metaphor on the science papers but not as an institutional basis of the capital flows directions. The paper aims to update the configuration of the global financial system, its dependence on the performance of US corporations and banks; to identify the sources of vulnerability of world finance and global liquidity from the fictitious capital of American financial markets. The methodology is theoretical pattern’ of financial capital movements and its real statistical market indicators comparison. The empirical base is statistical data about the financial flows and financial results especially about the US as a global financial center. Based on the results the authors have revealed an origin of fictive capital on the US bank sector by the justification for the conclusion of liquidity above the profitable as the purpose of financial operations. This conclusion is confirmed with the scale of off-balance sheet transactions of banks. Besides the regression between the prices of derivative’ basis assets and stock indexes has been shown. Also, the market capitalization of American companies is not sensitive to change in market liquidity indicators. The authors concluded that global financialization is supported by significant internal contradictions in the US economy. The source of contradictions is the financial mechanism for withdrawing liquidity from the sphere of production and circulation into the sphere of financial markets. Capital investment using instruments of the US financial market entails the threat of losing their liquidity. Forecasting the dynamics of the global economy without taking into account the role of fictitious capital, which is emerging in the American financial markets, leads to global vulnerability and may cause the next financial crisis.

Purpose The purpose of this paper is to present a decision support system (DSS) for a Colombian public utility company in order to aid decision-making at the operational level regarding route planning and travel time. The aim is to provide a tool to assist technicians that perform interruption and reconnection of domiciliary services for about 2,000 customers a day. Design/methodology/approach The real-life problem is modeled as a Single Depot Vehicle Routing Problem with Time Windows (SDVRP-TW), which is a well-known optimization problem in Operations Research/Management Science. A two-stage approach integrated into decision-making software is provided. The first stage considers the clustering of customers generated by a combination of the sweep and the k-means algorithms, while the second phase plans the routing of technicians using the nearest-neighbor and the Or-opt heuristics. The proposed approach is tested using real data sets. Findings In comparison with the current route planning approach, the proposed method is able to obtain savings in total travel times, improving operational productivity by 22.2 percent. Research limitations/implications Since the analysis is carried out based on mathematical modeling, assumptions about the relationships between variables and elements of the actual complex problem might be simplified. Although the proposed approach aids the route planning, decision makers make the final decisions. Practical implications The proposed DSS has a critical impact on actual operational practices at the company. Productivity and service level are improved, while reducing operational costs. The decision-making process itself will be improved so technicians and higher decision makers can focus on performing other tasks. Originality/value The real-life problem is modeled using mathematical programming and efficiently solved through a two-stage approach based on simple, quite intuitive, solution procedures that have not been implemented for such services. In addition, as actual data from the company is employed for experimental purposes, the solution approach is tested and its efficiency and efficacy are both validated in a realistic setting, hence providing realistic behavior for decision makers at the company.

Full textAbstract:
Introduction: Standard first line therapy (LOT) for patients (pts) with large B-cell lymphoma (LBCL) involves chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) or a similar regimen, e.g. R-CHOP with the addition of etoposide (R-EPOCH). While most pts respond, 30-40% of pts relapse or fail to achieve remission with 1st LOT. For those pts, the goal of curative 2nd LOT is typically platinum-based salvage chemotherapy in preparation for autologous stem cell transplant (ASCT). However, many pts (50% or more) do not qualify for intensive therapy, either due to age or comorbidities, or because they do not respond to or cannot tolerate salvage chemotherapy. For those further treatment options are limited. Objectives: In a sample of U.S. LBCL pts 65 and older, who have progressed to 2nd LOT and are eligible for ASCT, to compare the patient characteristics, treatments, costs and overall survival between pts who received SCT with those who did not. Methods: This retrospective cohort study used 100% Medicare Fee-for-Service Parts A/B claims data and Part D Prescription Drug Event data to identify pts ≥ 65 years of age, newly diagnosed with LBCL in 2012-2017, and who had ≥ 6 months continuous enrollment pre-diagnosis (baseline) and ≥ 12 months post-diagnosis, or who died after initiation of 2nd LOT. All were treated with a CHOP-like regimen 1st LOT and progressed to 2nd LOT. Eligible pts who received a 2nd LOT with a SCT-preparative regimen per NCCN guidelines were stratified into the "ASCT-intended" cohort, and the remainder into the "ASCT-not-intended" cohort. The ASCT-intended group was further subset into those who received a SCT and those who did not (Non-SCT). These 2 subsets formed the primary comparison groups. Baseline characteristics were age, gender, race, dual eligibility status (i.e. Medicare plus Medicaid), and Charlson-Deyo Comorbidity Index (CCI). Measures of utilization during follow-up (from initiation of 2nd LOT to loss to follow-up) were hospitalizations, outpatient and emergency department (ED) visits, and post-acute care. Costs during follow-up reflected standardized, inflation-adjusted, all-cause paid amounts. Utilization and cost metrics were standardized to per-patient-per-month (PPPM). Overall survival (OS) was measured from the start of 2nd LOT until death, disenrollment or the end of the study period. Results: 4,758 pts met all inclusion criteria. 3,713 (78%) did not receive a SCT-preparative regimen after 1st LOT. 1,045 pts (22%) received a SCT-preparative regimen and constituted the ASCT-intended group. Of these, 244 (23.3%) received a SCT and 801 (76.7%) did not. The remainder of this report focuses on a comparison of the SCT and non-SCT cohorts. Baseline characteristics, treatments, utilization and cost are summarized in Table 1. Both groups were predominantly white, but SCT pts were, on average, 5 years younger, slightly more likely to be male, and had slightly lower mean CCI scores. 13.1% of non-SCT pts were dual eligible vs. 4.5% of SCT (all p < .01 except Race). 93.9% of SCT procedures were autologous, and no pts had more than 1 SCT during follow-up. Non-SCT pts had higher all-cause utilization for all categories except for acute hospitalizations. The higher inpatient utilization for the SCT group may reflect the SCT procedure itself (94% of SCT were inpatient). A similar pattern was observed in the cost data, where Non-SCT pts incurred higher costs except for acute hospitalizations. Results for OS are summarized in Figure 1. Non-SCT pts had significantly lower rates of survival than SCT pts. 94.7% of SCT pts were still alive 6 months after initiation of 2nd LOT, whereas only 66.9% of non-SCT pts were. At two years post-2nd LOT, survival rates were 69.7% vs. 36.3%. Conclusions: In this study, only 23.3% of SCT-intended pts ultimately received it. The remaining 76.7% were SCT-intended but never received a transplant. Compared to the SCT pts, the non-SCT pts were older, had more comorbidities, had higher rates of healthcare utilization and costs post-2nd line therapy in all categories (except acute inpatient), and lower OS. 38.7% of non-SCT pts proceeded to additional lines of lymphoma-directed therapies beyond 2nd line, which may suggest that their clinicians felt that there was potential benefit to further treatment. These data suggest there may be unmet need for elderly pts with LBCL who are eligible for ASCT, but do not ultimately receive it. Disclosures Kilgore: Kite, A Gilead Company: Research Funding.

Mutually beneficial co-existence of the private and state sectors can be seen as proven in theory. The proof is the concept of a two-sector economy of A. Wagner (1835–1917), while, in Wagner’s view, the importance of the state sector should grow (Wagner’s law). State finance is understood in this context as a tool used to achieve social justice, and in general as a socially stabilizing element.In conditions of real Czech economy, the relationship between the state and private sectors is shown in the form of subsidies for businesses enterprises; although at first sight the available data do not demonstrate the key role of public finance. Another form of limited understanding of the importance of public funds is the concept of financial structure of a company understood by contemporary theory of finance of firm (in Czech context) as a set of sources for financing entrepreneurial activities – public funds are virtually not mentioned here.The aim of the paper is to contribute to correct this shift in understanding of the importance of public finance and to bring it nearer both to the original theoretical concept (A. Wagner) and to reality, both in quantitative and qualitative terms.Main focus of this paper is to the Czech Republic circumstances. For the comparison are here presented available data from other countries and global data as well.

Full textAbstract:
Purpose This paper aims to clarify whether assurance on non-financial corporate social responsibility (CSR) reports impacts the perceptions and decisions of banks as capital providers. The authors investigate the effects of the type of assurance provider and the level of assurance provided on decisions by banks to grant credit, make their own personal investments or recommend share purchases to their customers. The study aims to expand the domain of assurance on CSR reports (CSRR) by taking up a call by Cohen and Simnett (2015), who ask for behavioral research on how non-financial report’s intended users interpret and react to assurance. Design/methodology/approach The paper is based on an experiment case on a fictitious company with a 2 × 2 + 1 between-subjects design. To overcome concerns regarding external validity and to prove results in a real-world setting, the authors selected German bank directors as subjects due to the extremely high relevance of banks to the German economy. The authors investigated the perceptions of 69 bank directors and analyzed the influence of CSR assurance on their decisions. Findings The findings suggest that assurance positively influences confidence in CSRR and that, consequently, bankers are more likely to make favorable decisions toward the reporting companies, such as approving applications for credit, investing themselves in the company or recommending the purchase of shares to their clients. These effects are stronger when an accounting firm provides the assurance and when the assurance level is reasonable rather than limited. Research limitations/implications The arguments presented are, strictly speaking, limited to the case in the experiment and the views held by the bank directors at the time the authors sent out the questionnaires. Moreover, the cell sizes are quite small. Nevertheless, the authors were able to find highly significant results. Practical implications The main implication of the paper is that the purchase of CSRR assurance services has a positive effect on bank directors’ perceptions and decisions. They favor the provision of such services by accounting firms and they prefer a reasonable assurance level. Thus, it can be concluded that bank directors perceive quality differences between assurance providers, are able to recognize the difference between reasonable and limited assurance and that the related information is relevant for their decisions. Originality/value This paper fulfils an identified need to study the influence of CSRR assurance on decisions by bank directors. The observation of a high decisions-usefulness of CSRR assurance suggests that regulators should consider mandating some form of assurance on non-financial reports throughout the EU member states.

Full textAbstract:
Abstract Background Psychosis is associated with profound problems in interpersonal functioning. One of the key elements of social relationships is trust. Previous research has shown that patients with psychotic disorders display reduced trust in others. Reduced trust may lead to paranoid ideation and (as a consequence) to social withdrawal. Patients with psychotic disorders have fewer social contacts and less social support than comparison groups and they frequently have difficulties in developing and maintaining social relationships. This has also been found in young people with first episode psychosis (FEP), who report having less close friends. However, social functioning and social support are a strong predictor for future outcome: Social networks buffer against the impact of adversities. Social isolation, in turn, is associated with reduced quality of life, increased mortality and poor patient outcomes. Therefore, investigating trust and responses to social interactions in daily life is essential for developing interventions to improve social functioning in the field of schizophrenia research. This study investigated the underlying mechanisms of reduced trust in early psychosis patients by linking experimental trust data with emotional responses to day to day social interactions by means of experience sampling. We hypothesized that early psychosis patients, similar to chronic patients with schizophrenia, show more social withdrawal, and report higher levels of negative affect and lower positive affects when in company of others compared to controls. We expect that these social aspects are associated with reduced trust. Methods The sample consisted of 28 patients, of which 16 FEP and 12 patients at clinical high-risk, and 28 healthy controls. Participants performed a trust game during fMRI, and filled in a questionnaire about their social activities and their emotions and symptoms during these activities, 10 times a day, during a week. Results Patients had less social contact, and less contact with familiar others than healthy controls. Furthermore, social contact in general was associated with more positive affect. Contact with familiar others was associated with lower positive symptoms in the patient group, and with more positive affect and less negative affect in patients, whereas patients showed higher negative affect when being alone compared to controls. Empathy was a moderator between closeness of contact and mental health. Group differences in baseline trust, with patients showing reduced baseline trust, were not moderated by social withdrawal (the amount of social contact). Nor was baseline trust moderated by negative or positive affect when in company of others. Social contact was not significantly associated with neural activation. However, in the caudate and the temporo-parietal junction a decrease in activation was apparent, if participants showed more social withdrawal. Discussion The results indicate that familiar company is related to better outcomes in psychotic disorders. Subjects with low levels of empathy had more negative affect when in company of close others when compared to being in company of less familiar others. Furthermore, associations of daily social interactions with baseline trust and its neural correlates show link between reduced baseline trust and frequently being alone. Being alone affects neural responses to received trust in patients. Future research should investigate the role of perceived social support, and the motivation to engage in social contact with good friends or family. Treatment involving familiar contacts may be effective in patients with psychotic symptoms to facilitate social contact and strengthen their relationships.

Background:Due to the expiration of many originator biologics patents, their biosimilars (BS) have appeared and were put into clinical practice. The introduction of such drugs reduces the cost of treatment and thereby increases its availability. BS rituximab (RTX) Acellbia was developed by the Russian company “BIOCAD”. Its effectiveness and safety have been proven in two clinical trials. It was licensed in Russia for the treatment of rheumatoid arthritis (RA) in 2017.Objectives:To compare efficacy and safety of BSRTX and originator RTX (ORTX) in real clinical practice.Methods:RA patients fulfilling the EULAR/ACR 2010 criteria and followed-up at the V. A. Nasonova Research Institute of Rheumatology were included. All of them had previously received methotrexate without effect. They were divided into 4 groups. The first and second groups included patients who had not previously received biologics. Treatment with BSRTX was started in the first group, ORTX was administered in the second group. The third and fourth groups included patients who received ORTX with significant improvement. Patients of the third group were switched to BSRTX, in the fourth group treatment with ORTX was continued. ORTX and BSRTX were administered twice 500 mg over 2 weeks. The indication for repeated administration of ORTX and BSRTX was an exacerbation of RA. Patients were examined before the first or regular administration of ORTX or BSRTX and before the planned repeat course of treatment with these drugs. RA activity was evaluated with the DAS28. Adverse events (AE) were recorded. Data were tested for normality using the Kolmogorov-Smirnov test. Continuous variables are presented as mean ±SD if they obey normal distribution, and as median [quartile interval] if they were not consistent with normal distribution. Mann–Whitney U test was used for comparison between groups.Results:127 patients with RA were included. 66 patients had not previously received biologics. BSRTX was started in 35 of them and ORTX – in 31. 61 patients already received ORTHX with clinical improvement. 31 of them were switched to BSRTX, and 30 continued therapy with ORTX. The median interval between the baseline examination and the assessment before the second treatment course in the BSRTX group was 6 [5; 13] months, in the ORTX group – 7 [7; 11] months. In group 1 median DAS28 during follow-up decreased from 5,8 [5,2; 6,9] to 3,9 [3,1; 4,5], in group 2 – from 5,7 [5,2; 6,0] to 4,1 [3,8; 4,6], respectively. These changes were comparable in both groups. The mean duration of the interval between infusion of BSRTX or ORTX and repeated examination – 11,3±8,2 and 10,1±4,8 months, respectively. These differences are not significant. In group 3 median DAS28 at the baseline examination was 5,1 [3,9; 5,9], at the second one – 4,3 [3,8; 5,3], in group 4 – 4,6 [3,7; 5,4] and 4,2 [3,5; 5,2] respectively. These values did not differ significantly. The frequency and nature of adverse events during treatment with ORTX and BSRTX did not significantly differ. We did not observe serious AE and unexpected AE.Conclusion:The results of the present study show that efficacy and safety of BSRTX and ORTX were comparable when they were used as the first biologics and when switching from ORTX to BSRTX. BSRTX can be used in routine clinical practice for the treatment of RA.Disclosure of Interests:None declared

Full textAbstract:
With the rising growth of the telecommunication industry, the customer churn problem has grown in significance as well. One of the most critical challenges in the data and voice telecommunication service industry is retaining customers, thus reducing customer churn by increasing customer satisfaction. Telecom companies have depended on historical customer data to measure customer churn. However, historical data does not reveal current customer satisfaction or future likeliness to switch between telecom companies. The related research reveals that many studies have focused on developing churner prediction models based on historical data. These models face delay issues and lack timelines for targeting customers in real-time. In addition, these models lack the ability to tap into Arabic language social media for real-time analysis. As a result, the design of a customer churn model based on real-time analytics is needed. Therefore, this study offers a new approach to using social media mining to predict customer churn in the telecommunication field. This represents the first work using Arabic Twitter mining to predict churn in Saudi Telecom companies. The newly proposed method proved its efficiency based on various standard metrics and based on a comparison with the ground-truth actual outcomes provided by a telecom company.

Background:Baricitinib (BARI) is a JAK1-2 inhibitor approved for the treatment of adults with moderately to severely active rheumatoid arthritis (RA). RA-BE-REAL is a 3-year, prospective, observational study of adult RA patients (pts) evaluating adherence to treatment in clinical practice.Objectives:To describe pt and disease characteristics of pts enrolling into RA-BE-REAL in 5 European countries.Methods:The primary endpoint of RA-BE-REAL is time until discontinuation of initial treatment for all causes (excluding sustained clinical response) over a 24-month (M) period. Secondary endpoints include clinical and pt reported outcomes, healthcare resource utilization and treatment patterns over a 36M period. Two pt cohorts are assessed: cohort A, started treatment with BARI (2-mg or 4-mg), and cohort B, any other targeted synthetic (ts)DMARDs or biologic (b)DMARD (Fig. 1). Treatment initiation and changes are at the discretion of the pt and physician. Data is collected at baseline and at routine visits (~3M, 6M, 12M, 18M, 24M and 36M). Summaries are presented with t-test and chi-square test of independence.Results:Between October 2018 and March 2020, 1074 adult RA pts were enrolled from France, Germany, Italy, Spain, and UK. In cohort A, 88.2% of pts are treated with BARI 4-mg. At time of enrolment pts in cohort A are more likely to commence treatment as a monotherapy as compared to pts in cohort B who are more likely to commence treatment in combination with csDMARDs (p<0.001). Cohort A are more likely to be older (59.2 vs 57.0, mean years p=0.009) and have higher Health Assessment Questionnaire-Disability Index (HAQ-DI) scores (1.4 vs 1.3, p=0.03). A greater percentage of cohort A pts have received prior treatment with either 1 b/tsDMARD (15.3 vs 11.0%), 2 b/tsDMARD (20.2 vs 14.7%) or >2 b/tsDMARD (15.9 vs 12.9%), while cohort B are more likely to be treatment naïve (61.4 vs 48.5%). There are no significant differences in other baseline characteristics shown in Table 1.Conclusion:There are few but potentially clinically important differences between cohorts. Pts in cohort A are more likely to be older, have a longer disease duration, have received prior b/tsDMARD treatment, and are more likely to receive treatment as a monotherapy as compared to pts in cohort B.Figure 1.Study Design.

Journal of Industrial Engineering and Management 10, no. 4 (2017): 623. http://dx.doi.org/10.3926/jiem.2116.
Full textAbstract:
Purpose: The present paper focuses on the modelling and solution of a large-scale personnel transportation system in Mexico where many routes and vehicles are currently used to service 525 points. The routing system proposed can be applied to many cities in the Latin-American region.Design/methodology/approach: This system was modelled as a VRP model considering the use of real-world transit times, and the fact that routes start at the farthest point from the destination center. Experiments were performed on different sized sets of service points. As the size of the instances was increased, the performance of the heuristic method was assessed in comparison with the results of an exact algorithm, the results remaining very close between both. When the size of the instance was full-scale and the exact algorithm took too much time to solve the problem, then the heuristic algorithm provided a feasible solution. Supported by the validation with smaller scale instances, where the difference between both solutions was close to a 6%, the full –scale solution obtained with the heuristic algorithm was considered to be within that same range.Findings: The proposed modelling and solving method provided a solution that would produce significant savings in the daily operation of the routes.Originality/value: The urban distribution of the cities in Latin America is unique to other regions in the world. The general layout of the large cities in this region includes a small town center, usually antique, and a somewhat disordered outer region. The lack of a vehicle-centered urban planning poses distinct challenges for vehicle routing problems in the region. The use of a heuristic VRP combined with the results of an exact VRP, allowed the obtention of an improved routing plan specific to the requirements of the region.

Full textAbstract:
Introduction: Patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) can be treated with 3 resource intense options: autologous hematopoietic cell transplant (Auto-HCT), allogeneic HCT (Allo-HCT), or autologous anti-CD19 chimeric antigen receptor T-Cell (CAR T) therapy after two or more lines of systemic therapy, depending on the clinical scenario. Our aim was a comparative analysis of healthcare resource utilization (HCRU) and associated costs for matched samples of Medicare patients for treatment planners, payers, and policy-makers. Methods: This study utilized a retrospective, observational cohort design. Data were derived from the Center for Medicare and Medicaid Services (CMS) 100% Medicare Fee-for-Service (FFS) Part A and B claims data. Part D data for the study period were not yet available, so pharmacy claims for oral medications were not evaluated. Patients with DLBCL were included if they received CAR T or Auto-HCT between 10/1/2017 and 3/31/2019 or Allo-HCT between 7/1/2012 and 3/31/2019. Patients with more than 1 CAR T or HCT were excluded. The index date was the date of initiation of the procedure. To allow for evaluation of patient characteristics and treatments pre- and post-procedure, patients must have been continuously enrolled in Medicare FFS for 6 months prior to (PRE) and after (POST) the index date. Patients who died during the POST period were included. The 3 cohorts CAR T, Auto-HCT, and Allo-HCT were matched on baseline clinical characteristics using 1:1 propensity score matching with a caliper of 0.05, with Auto-HCT and Allo-HCT patients assumed to be clinically distinct populations offered at different lines of therapy and so were matched to CAR T patients separately. Due to limitations of the data, we were not able to match patients by line of therapy. Baseline characteristics were age, gender, race, census region, dual eligibility status (i.e. Medicare plus Medicaid), ECOG-PS (derived from claims using a validated, published method), Charlson-Deyo Comorbidity Index (CCI) and recent history of DVT/PE or cytopenias. Measures of HCRU were all-cause hospitalizations, outpatient, and emergency department (ED) visits. Costs were total paid amounts. HCRU and cost data were calculated for the 6 months PRE and POST, but do not include the utilization and costs associated with the index procedure itself. Results: The CAR T/Auto-HCT analysis included 175 patients each, while the CAR T/Allo-HCT analysis included 142 patients each. All cohorts had a median age of 69-70, with slightly more females, mostly ECOG 0-1, and were predominantly white. Only 10-15% were dual eligible. Although all groups had a median CCI of 4, the CAR T/Auto-HCT patients yielded slighter higher mean comorbidity scores (5.2-5.4) than CAR T/Allo-HCT (4.8). For the CAR T/Auto-HCT comparison (Table 1a), Auto-HCT utilization was higher than CAR T on all acute care hospitalization measures and mean total medical costs were 35% higher ($85,382 vs. $63,081, respectively) during PRE. During POST, all measures were lower than PRE for both groups including total medical costs ($25,277 and $33,876, respectively). The reductions were greater for Auto-HCT than for CAR T, resulting in Auto-HCT having lower POST utilization and costs than CAR T for all measures except % of patients with outpatient encounters. Allo-HCT utilization was higher than CAR T on all PRE measures including cost ($92,119 and $70,105, respectively, Table 1b) except ED visits. For POST vs. PRE, CAR T HCRU and costs declined ($34,477) similarly to that in the Auto-HCT comparison. But for Allo-HCT, acute care length of stay increased at POST compared to PRE, and total medical costs were relatively unchanged ($82,847) POST. POST HCRU and cost differences between these groups are not attributable to different survival rates, as no differences were seen. Conclusions: In this observational descriptive analysis, HCRU and costs for Auto-HCT patients were higher during the 6 months pre-HCT compared to a matched group of CAR T patients but were lower during the 6 months post-HCT. For a matched group of Allo-HCT patients, however, the post-HCT period showed HCRU and costs that were equal to or higher than pre-HCT and were higher than CAR T during the same period. Understanding the relative HCRU and costs associated with these 3 procedures common to relapsed/refractory DLBCL will allow for better HCR planning.

Full textAbstract:
Acquisition of real-time particulate matter (PM) data is proposed by the use of a Rupprecht and Patashnick Company, Inc. Series 110 diesel particulate monitor tapered element oscillating microbalance (TEOM) mass measuring device. The objectives of using a TEOM diesel particulate analyser were to validate its collection capability and evaluate its real-time transient characteristics. Conventional PM measured using dilute diesel exhaust filtration was used as the base line for evaluating the TEOM collection capability. Real-time mass rate data were separated into positive and negative values, then integrated over the duration of the test. The integrated positive mass was divided by the integrated negative mass to create a ratio that is indicative of real PM collected versus moisture released from the filter. Tests were performed on heavy-duty diesel engines on a stationary dynamometer using the US Heavy Duty Federal Test Procedure speed and load cycle. TEOM sample tube temperatures at 35°C yielded the best TEOM-conventional PM filtration mass ratio. However, as sample path temperatures decreased, a decrease in the positive-negative mass ratio occurred. A compromise between conventional filter agreement and real-time data was made in selecting the temperature set point of 40°C as the most desirable sampling temperature. The sample flowrate was varied from one to four litres per minute. A comparison of the TEOM with a conventional filter decreased as the TEOM flow increased. The 1 l/min set point provided the best TEOM-conventional filtration ratio. The positive-negative mass ratio increased as flow decreased. The flow-rate of 3 l/min was chosen to be a compromise between the TEOM-conventional filtration mass ratio and real-time results. The best TEOM-conventional filtration ratio measured was 0.97. The best set of test results was a three-test averaged TEOM-conventional filtration ratio of 0.92 with a coefficient of variance of 0.15 per cent.

This paper employs a simulation model in a Supply Chain Management (SCM) system. This study is one of the first to present simulation model of inventory control system in supply chain management using barcode and Radio Frequency Identification (RFID). The main objective of this model is to compare two inventory systems in a supply chain, one using RFID, versus the barcode. The model will help company to consider moving from a barcode system to the RFID application. A quantitative analysis based on a simulation model is developed. The model runs for both systems using ARENA simulation software with a comparison between the two systems. Furthermore, the simulation model is tested by applying three different types of demand for both scenarios. The results have shown that regardless of demand distribution pattern and customer order rate, the outcomes of the model are consistent and provide promising RFID technology adoption to improve inventory control of the entire supply chain system. The installation and unit cost of RFID implementation were estimated and considered to be the main barrier. Such model can offer the policymakers insight into how RFID might improve SCM system performance. Additional test has been conducted for demand with normal and triangular distributions using real data provided by ABC-Dubai Company. The results obtained from running the two models for these distributions are consistent with the original results.

Full textAbstract:
Has the Royal Shakespeare Theatre in Stratford become an expensive irrelevance – actually hindering what should be the real work of the parent company, which has to expend so much of its cash and its energy in running it? Certainly, some were tempted to suggest so when the RSC's most exciting Shakespeare productions of the ‘seventies seemed to be emerging from the spartan environment of The Other Place. Now, Graham Holderness, through a detailed comparison of last season's main-house revival of The Taming of the Shrew and the Swan production of Titus Andronicus, argues that the creation of the Swan – a theatre space specifically but not ‘archeologically’ designed for Elizabethan and Jacobean plays – heightens the sense of a ‘contradictory relationship’ between the RSC's two ‘classical’ houses in Stratford. Graham Holderness, author of several studies in the fields of Renaissance drama and the modern novel, is presently Head of Drama at Roehampton Institute.

Full textAbstract:
The main objective of this study is validation of a proposed mathematical model for the estimation of the influence of kneading arms geometries on rheological properties of dough. Two types of kneading arms are studied, both mounted on the same industrial kneader type. A tridimensional numerical simulation for dough kneading is used for obtaining the Eddy viscosity values, which were introduced in a mathematical model for calculation of the dough�s resistant torque at the kneading arms, at 15 seconds time intervals. Real time torque diagrams developed by the kneading arms, were traced using a system for data acquisition and dough kneading control (SOPF), developed by BioTechnologiCreativ Company. These diagrams were used for mathematical model validation using the comparison between the torque values measured in real time and the ones obtained using the mathematical model, in which was introduced the Eddy viscosity value obtained with the 3D simulation. The obtained results have very similar values. With this study it is possible to predict the rheological behavior of dough during kneading process. Anticipation of the kneading diagram form can be helpful in the optimization of the entire technological process and the obtaining of dough with uniform consistency and optimal development during the stages of the manufacturing process.

Purpose – Virgin Atlantic Cargo is one of the largest air freight operators in the world. As part of a wider strategic development initiative, the company has identified forecasting accuracy as of strategic importance to its operational efficiency. This is because accurate forecast enables the company to have the right resources available at the right place and time. The purpose of this paper is to undertake an evaluation of current month-to-date forecasting utilized by Virgin Atlantic Cargo. The study employed demand patterns drawn from historical data on chargeable weight over a seven-year-period covering six of the company's routes. Design/methodology/approach – A case study is carried out, where a comparison between forecasting models is undertaken using error accuracy measures. Data in the form of historical chargeable weight over a seven-year-period covering six of the company's most profitable routes are employed in the study. For propriety and privacy reasons, data provided by the company have been sanitized. Findings – Preliminary analysis of the time series shows that the air cargo chargeable weight could be difficult to forecast due to demand fluctuations which appear extremely sensitive to external market and economic factors. Originality/value – The study contributes to existing literature on air cargo forecasting and is therefore of interest to scholars examining the problems of overbooking. Overbooking which is employed by air cargo operators to hedge against “no-show” bookings. However, the inability of air cargo operators to accurately predict cargo capacity unlikely to be used implies that operators are unable to establish with an aspect of certainty their revenue streams. The research methodology adopted is also predominantly discursive in that it employs a synthesis of existing forecasting literature and real-life data for accuracy analysis.

The increasing importance of considering environmental issues as a part of the corporate social responsibility, which has environmental and social impacts as well as affects the image and competitiveness of a firm, has encouraged companies to revise their major processes of supply chain management (SCM). Since the performance of a company heavily relies on its suppliers, it is of vital importance to incorporate environmental criteria into supplier selection problem to satisfy both conventional and environmental criteria, which have only been considered by a limited number of studies. Therefore, following a brief review of green supply chain management (GSCM) and sustainable supply chain management (SSCM) concepts and investigation of supplier selection approaches, this study after focuses on a modified Delphi method that has been applied to determine supplier selection criteria. Also, the intuitionistic fuzzy value (IFV) and interval value intuitionistic fuzzy (IVIF) have been utilised for supplier evaluation regarding the subjective nature and uncertainty of judgment. By using the Choquet Integral operator and fuzzy measures, the best supplier has been selected, and the comparison between IFV and IVIF has been made. This methodology has been applied to a manufacturing company to assess the applicability of the proposed methodology. The proposed methodology can be used for real world problems that contain fuzziness or interacting decision criteria. Moreover, due to a high level of expert involvement in the decision-making process, we claimed that the knowledge of experts has been utilised constructively.

<span>This paper presents a design of 3D modeling of Multimode and Single Mode Fiber using SolidWorks. Fiber technology is essential that presents optical fiber is the fastest optical cable laid by Internet Service Providers in network communication. The current design of both fibers has less detail animation on technical specifications of light propagations and cladding. Thus, characterization difficulties occur between this two fiber optics cables. It also has less promotion in media publications such as 3D model design as guidance to users. This paper presents details on 3D modeling of multimode mode and single mode fiber specifications held in the industry market. A 3D design with SolidWorks and comparison of both fiber characteristics are presented. Based on the 3D designed model, users are analyzed on their perspective and searching information which benefits telecommunication’s company. Technical calculations like core-cladding diameter ratio in microns are animated. The propagation of light in 3D single mode and multimode fiber is simulated using SolidWorks animator that presents it real fiber conditions. Result presents 10 most country searching used of both fiber cables and the difference in users search for both cables. A number of user’s search presents 3% more of multimode than single mode fiber search cases. This research is significant in presenting an animator of single and multimode fiber to users of network infrastructure development especially network developers and Telecommunications Company which can present it lively with animator transitions.</span>

Since 2010, the Czech State Forest Enterprise has been inviting timber-harvesting tenders while insisting on the forestry company purchasing the timber from the felled trees as well. To win, a tender must offer the greatest difference between the price of the timber purchased and the cost of the operations. Thus, the forest companies are now facing new problem: apart from minimizing the logging costs they are searching for a cross-cutting and mill-distribution strategy that maximizes the selling price of the harvested timber. The optimization model devised by the present paper provides support for finding an optimal timber selling strategy and, as an important contribution, include a detailed plan for cross-cutting the logs and assign them to the particular customers. We keep the support accessible via common office software and the cross-cutting and customer-assigning problem is formulated as a linear programming model for EXCEL, a particular real-world problem is solved and, using expert comparison, the model appears to provide very good results.

In recent years, with the development of advanced technologies for data collection, real-time bus control strategies have been implemented to improve the daily operation of transit systems, especially headway-based holding control which is a proven strategy to reduce bus bunching and improve service reliability for high-frequency bus routes, with the concept of regulating headways between successive buses. This hot topic has inspired the reconsideration of the traditional issue of fleet size optimization and the integrated bus holding control strategy. The traditional headway-based control method only focused on the regulation of bus headways, without considering the number of buses on the route. The number of buses is usually assumed as a given in advance and the task of the control method is to regulate the headways between successive buses. They did not consider the bus fleet size problem integrated with headway-based holding control method. Therefore, this work has presented a set of optimal control formulations to minimize the costs for the passengers and the bus company through calculating the optimal number of buses and the dynamic holding time, taking into account the randomness of passenger arrivals. A set of equations were formulated to obtain the operation of the buses with headway-based holding control or the schedule-based control method. The objective was to minimize the total cost for the passengers and the bus company in the system, and a Monte Carlo simulation based solution method was subsequently designed to solve the optimization model. The effects of this optimization method were tested under different operational settings. A comparison of the total costs was conducted between the headway-based holding control and the schedule-based holding control. It was found that the model was capable of reducing the costs of the bus company and passengers through utilizing headway-based bus holding control combined with optimization of the bus fleet size. The proposed optimization model could minimize the number of buses on the route for a guaranteed service level, alleviating the problem of redundant bus fleet sizes caused by bus bunching in the traditional schedule-based control method.

Google Earth imagery is frequently used in science, engineering, and other mapping applications. However, the company owning the tool announced that the data available in its geographical products is only approximate, so its accuracy is not officially documented. The Google Earth imagery in many areas around the world has been independently checked by scholars and third body parties. The estimated accuracies are found to largely vary depending on various factors but mainly due to, the imagery source or the image resolution. Positional accuracy testing methodology may also affect the assessment results. In processing, there should be many points around the tested area in order for the comparison to be more reliable. In this paper, the horizontal accuracy assessment was carried on the Google Earth imagery in Duhok city using the traces collected via GPS in Real Time Kinematic (RTK) technique. About 38 km of trajectory was collected for the two main roads in the selected area. Via semi-automated method, the points from RTK trajectory were compared to the corresponding extracted points from the centerline of the road network of Google Earth imagery. The nearest neighboring method through buildup algorithm was considered for comparison between both sets of data. Root Mean Square Error (RMSE) and maximum error were computed for horizontal positional coordinates and found to be 1.53m and 7.76m, respectively.

Objective – The objective of this research is to obtain empirical evidence about the effect of real earnings management that is proxied by abnormal Cash Flow from operating and discretionary expenses towards fraudulent financial reporting. Methodology/Technique – The objects in this research are companies listed on the Indonesian Stock Exchange (idx) between 2011 and 2015 comprised of companies that have engaged in fraudulent activities as well as those that have not, to enable a comparison to be made. The companies that have engaged in fraudulent financial reporting were obtained from a list issued by the Financial Services Authority (OJK), being the agency that oversees the capital market in Indonesia. The sampling is conducted using purposive sampling. Secondary data is used, and the hypotheses are testing using logistic regression analysis. Findings – The results of this research show that: (1) Real Earning Management proxied by Abnormal Cash Flow from operating activities (CFO) have a significant effect towards Fraudulent Financial Reporting (FFR), (2) Real Earning Management proxied by Abnormal Discretionary Expenses does not have an effect on Fraudulent Financial Reporting (FFR) and (3) Real Earning Management that is proxied by Abnormal Cash Flow from operating (CFO) and Abnormal Discretionary Expenses have a simultaneous and significant effect on Fraudulent Financial Reporting (FFR). Novelty – Based on these findings, this research provides insight to companies to enable them to give greater attention to abnormal cash flow from operating activities due to the effect this has on companies that are suspected of committing irregularities in its operational activities. This is important because fraudulent reporting can erode investor’s confidence and thereby reduce investment in the company. Type of Paper: Empirical.
