The method used for traditional “Phase I” Environmental Site Assessments (ESA’s) has required staff to physically walk the rights-of-way (ROW). In order to compete the ESA in a more timely and cost-effective manner than traditional techniques allowed, URS Corporation (URS) contracted LinearVision (LV) to fly the utility ROW and collect low-level, airborne, geo-referenced videography, complemented with geo-referenced still-imagery to enable URS to complete the Phase I ESA data analysis in their office. The data provided enabled URS’s analysts the ability to access all ROW points of interest in their Geographic Information System (GIS), and “fly” the line with oblique and downward perspectives from their computer screen. The digital video could be sped up or slowed down allowing URS the ability to review each frame for careful, detailed analysis, and identify potential recognized environmental conditions (RECs) and encroachment upon the ROW. The high-resolution still-imagery provided URS the ability to zoom into the potential REC for a closer inspection of site features, vegetation, and surrounding land use. URS created a database of potential RECs and areas of interest along with a simple user interface as a deliverable to the client, which allows the user to link directly to specific video frames and high-resolution photographs for their own review and analysis. The cost of the airborne data capture and processing was substantially less than a traditional Phase I ESA. Furthermore, the video and high-resolution images provided for a more comprehensive analysis tool, which can be reviewed by multiple analysts and catalogued for future reference by third parties. An additional benefit is that the high-resolution photographs can be imported into AutoCAD or other software for development of maps and figures. Overall, the net result of low-level GIS integrated videography is enhanced quality of data and a 50% reduction in total cost for the ROW project as compared to traditional Phase I ESA methodology.

In this paper we propose a deformable registration framework for high resolution satellite video data able to automatically and accurately co-register satellite video frames and/or register them to a reference map/image. The proposed approach performs non-rigid registration, formulates a Markov Random Fields (MRF) model, while efficient linear programming is employed for reaching the lowest potential of the cost function. The developed approach has been applied and validated on satellite video sequences from Skybox Imaging and compared with a rigid, descriptor-based registration method. Regarding the computational performance, both the MRF-based and the descriptor-based methods were quite efficient, with the first one converging in some minutes and the second in some seconds. Regarding the registration accuracy the proposed MRF-based method significantly outperformed the descriptor-based one in all the performing experiments.

Small and medium enterprises (SMEs) have very significant contribution to economic growth of the countries as more than 95% of companies worldwide and employment are represented by the SMEs industries. Therefore, in increasing the harmonization of reporting standard of SMEs, Malaysia is moving aggressively towards the efforts by introducing the Malaysian Private Entity Reporting Standard (MPERS) for SMEs starting from 1st January 2016 onwards. MPERS is seen to bring opportunities to the business as it is adoption of international standard that has been designed to fits the local needs and the customization to the Malaysian business environment could ensure comparability of the locals with the international business. Hence, this research attempt to 1) examine the perceptions of accounting practitioners on MPERS implementation and 2) identify the problems encountered in applying MPERS in SMEs. This study provides pioneering evidence on the problems of the practitioners encountered when applying the MPERS through the 176 questionnaires survey that have been distributed to the accounting practitioners that involve with MPERS implementation for SMEs in Malaysia. The insights and perceptions obtained highlighting new dimensions to the inherent problem such as issues of consistency and guidance in applying the MPERS with the cost-effective manner. Thus, the issues of differences in judgements among the practitioners become a phenomenon in relation to the application of MPERS for SMEs. The findings of this study are of interest to standard setters and SMEs stakeholders in Malaysia and other countries.

After the long-term operation of reservoir facilities, they will become nonoperational due to the material deterioration and the performance degradation. One of crucial decisions is to determine the maintenance or replacement of the facilities in a cost-effective manner. Conventional replacement models seldom consider the maintenance effect. The facilities after maintenance are generally not as good as new, but are relatively restored. The target of this study is to establish a replacement decision model of the reservoir facilities under imperfect maintenance. By combining the theories of reliability analysis, imperfect maintenance, and engineering economics, the best timing of replacement that achieves cost-effectiveness is analyzed and proposed. Lastly, based on the design of experiments (DOE) and simulation, the regression curve chart for the economical replacement decision is established. Once the failure rate, the age of recovery after maintenance, and the ratio of maintenance cost to replacement cost are estimated based on historical data, the cost-effective replacement time of hydraulic machinery facilities will be efficiently determined.

High resolution pattern of silver nanoparticles has received great attentions for its application in various electronic devices such as touch screen, OLED and solar cell. However, traditional printing techniques cannot meet the demands for high resolution. Here, we introduce a new method to prepare fine lines of nanoparticles less than 10 μm by microcontact printing (μCP), which was first used to surface modification and patterning. The PDMS stamp with 10 μm line width and space was prepared by replication of etched silicon template. Conductive silver ink was transferred from resource substrate to the target substrate using the PDMS stamp during μCP process. Transferred line patterns of silver nanoparticles were conductive and the resistance was about 100 Ω using two-point probe measure method after baking at 150°C for 30 min. We found that printing pressure imposed on the PDMS stamp was significant for the quality of lines during the μCP process and appropriate printing pressure was 7~9 KPa. The technology can be used as universal method to transfer other nanomaterials and create fine patterns with a simple and cost-effective manner.

A method of determining the optimal number of inspectors and/or working time required on a specific SPC activity is presented in the study. The issue of inspection manpower planning is handled as a constrained optimization problem. The optimization strategy is not only to minimize the avoidable surplus quality loss due to failure of detecting the out-of-control states but to determine the cost of inspection manpower from the perspective of deploying an appropriate amount of inspection manpower in a cost-effective manner, and meanwhile the values of sample size, sampling interval and control limits of control charts are also determined. The result obtained indicates that the total cost (or loss) can be substantially reduced if implementing control charts was equipped with adequate inspection manpower.

The formal Root Cause Analysis (RCA) process consists of a structured approach to identifying the underlying factors that result in the unwanted outcomes of one or more typically negative past events (chronic or sporadic). The process helps to identify what systems or behaviors need to be modified to prevent recurrence of similar outcomes. The fundamental driver of the RCA is to eliminate the causes that lead to the unwanted event rather than addressing the symptoms of the event. This generally leads to multiple corrective actions rather than a single solution. Based on various root causes analyses conducted by a department in Enbridge Pipelines since 2006, various benefits provided by RCA exercises are highlighted in this paper. The findings were mainly derived from completed RCAs as well as RCA team member surveys. Firstly, the cost effectiveness of the RCA process was identified as a primary driver for this exercise. For example, one RCA involving a multidisciplinary team of 8 members, costing approximately $35,000, led to $1M in recommended solutions generating $16M in potential savings. In other words, each of the 350 hours spent on the RCA produced $8,571 in savings underlining the value creation to the company. Secondly, the RCA process combined with the power of the team reflection led to the identification of new issues which were causing other revenue losses to the company. Because these issues were not part of the defined scope of the original RCA, their root causes were not be immediately assessed but nevertheless their impact could easily be quantified and forwarded to Management for review. The third benefit highlighted by RCAs is more of an educational benefit to team members and subsequently the organization. Through cross functional examination of the issues and events, the team members became aware and educated on issues that would not have otherwise been apparent. Additionally, by working through the RCA methodology, the team members enhanced their problem solving abilities which benefit their everyday work. In conclusion, other than identifying techniques to preclude unwanted outcomes and providing cost saving opportunities in a very cost effective manner, RCAs can be considered as an effective knowledge enhancement tool for an organization.

Background . Refractory or relapsed mantle cell lymphoma (R/R MCL) is generally associated with poor outcomes; median overall survival (OS) is 4-5 years. First generation Bruton's tyrosine kinase inhibitor (BTKi) (Ibrutinib) and second generation BTKi (acalabrutinib and zanubrutinib) have led to significant improvements in efficacy and safety over conventional chemoimmunotherapy in treating R/R MCL. In the absence of direct head to head clinical trials compare between BTKi, indirect comparisons between the first and second BTKi generations show possible differences in safety and efficacy. We used existing evidence from phase I/II clinical trials for second BTKi generation to evaluate the cost-effectiveness of ibrutinib vs acalabrutinib vs zanubrutinib in treating patients with R/R MCL from the US payer perspective. Methods. A Markov model with two health states (progression-free [PF] and progression or death) was specified. Kaplan-Meier (KM) curves of PF survival (PFS) from the phase III trial by Dreyling et al. (Lancet 2016) for ibrutinib, the phase II trial by Wang et al. (Lancet 2018) for acalabrutinib, and the phase I/II trial by Tam et al. (Blood 2019) for zanubrutinib were fitted to exponential distributions to extract transition probabilities between the two health states for each drug. Wholesale acquisition costs (WAC) were obtained from RedBook and costs of adverse events management were derived from the literature. The analysis was conducted over a lifetime horizon with health utility outcomes and costs discounted at 3.5% per year after the first year. The cost and PFS life years (LYs) and PFS quality-adjusted LYs (QALYs) for each treatment, the incremental PFS LYs and PFS QALYs gained with acalabrutinib or zanubrutinib over ibrutinib, and the incremental cost-effectiveness ratio (ICER) and cost-utility ratio (ICUR) were estimated in both base and probabilistic sensitivity analyses (PSA: 100,000 simulations). Results. As detailed in the table, acalabrutinib and zanubrutinib were associated with better clinical outcomes than ibrutinib, with incremental PFS LYs gained of 1.61 and 0.98, and incremental PFS QALYs of 1.27 and 0.77, respectively. The incremental costs when comparing acalabrutinib and zanubrutinib with ibrutinib were $110,931and $64,624, respectively. In probabilistic analyses, the ICERs ($61,689/LYg for acalabrutinib; $53,438/LYg for zanubrutinib) and ICURs ($86,750/QALYg for acalabrutinib; $82,897/QALYg for zanubrutinib) were lower than the US willingness to pay (WTP) threshold of $100,000 to $150,000 per QALY for cancer treatment. At WTP of $100,000, the cost-effectiveness acceptability curves showed the probabilities of acalabrutinib, zanubrutinib, and ibrutinib being cost-effective to be 50%, 34%, and 16%, respectively. Conclusions. Acalabrutinib is more cost-effective compared with ibrutinib and zanubrutinib and improves health outcomes more in R/R MCL patients. This analysis using phase I/II trials should be validated as additional trial and real-world evidence about efficacy, safety, and associated health-related quality of life outcomes. Based on the current data, acalabrutinib offers the most cost-effective treatment option in R/R MCL.

ABSTRACT One challenge for trustees in a natural resource damage assessment (NRDA) is to adequately quantify natural resource injuries in a cost-effective manner. This is particularly true for smaller spills, where the cost of more expansive and more expensive injury assessment studies could dwarf the cost of the restoration actions to compensate for those injuries. The need for cost-effective assessments must he balanced against the need for the assessment methods to be technically defensible and useful in identifying and scaling appropriate restoration actions. In this paper, it is shown how the injury assessment results from the Lake Barre oil spill of May 1997 (which released 6,561 barrels of crude oil) were used to help inform trustees about the likely magnitude of injury for two smaller crude oil spills in Louisiana. For the Lake Barre spill, the trustees developed an incident-specific model—adapted from the Type A model—to quantify injury to birds and aquatic fauna. The results of this model were used to evaluate a restoration offer as compensation for these injuries from the responsible party (RP). Subsequently, the results of the Lake Barre assessment were used to help quantify injury to birds and aquatic organisms for the September 1998 release of up to 1,500 barrels of crude oil from a well blowout into Lake Grande Ecaille. The National Oceanic and Atmospheric Administration (NOAA) again used the Lake Barre results to quantify injury to water column organisms for a November 1999 release of 850 barrels of crude oil from a pipeline in Four-Bayou Pass. Estimating injury by extrapolation from one spill to similar spills represents one cost-effective approach toward quantifying injury for small incidents, and should be considered as a potential injury assessment method for those spills where it is impractical or otherwise difficult to justify conducting large incident-specific injury studies. This technique can be done quickly, potentially speeding the settlement and restoration implementation process, thereby compensating the public in an expeditious manner.

Transplantation is considered the treatment of choice for end-stage organ failure in most organ systems. Kidney transplantation is cost-saving as compared with dialysis, and the cost utility of liver transplantation is favorable compared with other accepted medical interventions; nonetheless, transplantation is an expensive endeavor. As a result, both hospitals and payers have made considerable efforts to try to limit the costs associated with transplantation; these efforts have resulted in complicated reimbursement schemes and a variety of models to deliver care. It is in this context that many institutions have looked to incorporate advanced practice professionals in the care of transplant patients. The ability to use advanced practice professionals in a cost-effective manner can be enhanced by an understanding of how reimbursement in transplantation works and the legal and financial implications of their employment.

Abstract Alloimmunization to red cell antigens can seriously compromise the treatment of chronically transfused sickle cell patients by increasing the risk of delayed hemolytic transfusion reactions and decreasing the availability of suitable red cell units. In an effort to reduce the rate of alloimmunization, many institutions routinely provide transfusions that are phenotypically matched for selected red cell antigens. Controversy exists in this approach with some advocating the use of extensive matching protocols in which 9 or more red cell antigens are screened while others follow a more limited approach in which only 3–5 antigens are screened. Neither the relative clinical efficacy nor the cost-effectiveness of these approaches has been compared. In our institution a limited phenotype matching program was instituted in June 1999 in which red cells provided to all pediatric sickle cell patients are negative for C, E, and Kell antigens only. All patients are screened for the presence of red cell allo-antibodies prior to each transfusion and additional phenotype matching was performed for patients who develop specific antibodies other than C, E and/or Kell. We present here our experience with this limited phenotype matching approach in 169 pediatric sickle cell patients. The patients in our study have received a mean of 100.7 red cell transfusions (range 1–555). Overall, 36 (21.3%) patients developed at least one red cell alloantibody. However, 15 of these patients had developed antibodies to C, E, or Kell (or a combination) as a result of transfusion prior to referral to our hospital or as a result of transfusion here, prior to the routine implementation of our limited matching program. Therefore, only 21 patients (12.4%) developed red cell alloantibodies that could not be prevented by the consistent use of our protocol. These antibodies include; Jka (4), M (4), Fya (3), S (3), Cw (3), Lua (3), V (2), Jsa (2), and Lea, Leb, Kpa, Kna, Jkb, c (1 each). The rate of antibody production was 0.17/100 units transfused. Our results favorably compare with other reports of more extensive phenotypic matching programs (e.g, 6.7% of patients with red cell alloantibodies; 0.06 antibodies/100 units transfused). In addition, only 6 of our patients (3.6%) developed multiple (non-C, E, Kell) allo-antibodies. In 3 of these patients the antibodies developed were of questionable clinical significance (Lea, Leb, Kna) or would generally not be screened even in the most thorough phenotype matching program (Cw, Lua). Among our patients with multiple alloantibodies, compatible red cell units were easily available with 4–13% of ABO/Rh compatible units collected from a non-ethnically selected population being suitable. The extended screening carried out for this limited number of patients (3.6%) is a far more cost-effective and sustainable approach for a large sickle cell treatment program than would be possible with an extended phenotyping program including essentially all patients. It should be noted that none of our patients have demonstrated clinical evidence of either acute or delayed hemolysis. Finally, it is important to consider the relative cost-effectiveness of various phenotype matching protocols. At an approximate cost of $200 for each red cell unit and a fee of $85 for each additional antigen screened by our local blood supplier, each unit of red cells for our patients costs $455. In screening programs requiring more extensive matching (8–9 antigens screened) the cost per unit would be almost double this amount ($880–$965). Our study suggests that this limited antigen matching is effective in reducing alloimmunization in chronically transfused pediatric sickle cell patients and additionally does so in a more cost-effective manner than more extensive screening programs. Finally, even in those patients who ultimately developed red cell antibodies, the availability of suitable red cell products was never seriously compromised.
