Abstract:
Introduction: First-case on-time starts (FCOTS) is an established metric of perioperative efficiency, impacting global perioperative throughput. Late-arriving surgeons are a common cause of late operating room (OR) starts. This project reflects a quality improvement effort to reduce late surgeon arrivals by 30% for 24 months and improve FCOTS. Methods: A multidisciplinary perioperative leadership team developed clear expectations, including tracking, roles, review processes, and consequences. These were broadly communicated among stakeholders, and feedback was incorporated. A new same-day surgeon-to-surgeon feedback mechanism was instituted for late surgeon arrivals, allowing for surgeon feedback and reiteration of expectations. Results were prospectively tracked for 24 months before and following implementation. Results: Late surgeon arrivals decreased by 45%, from 23.6 to 13 per month for 24 months before and following implementation, respectively (P < 0.001). Balancing measures did not see increases for the same periods. FCOTS increased from 66% to 72% postimplementation (P < 0.001). Statistical process control P-charts demonstrated centerline shifts for both metrics. Conclusions: Development and communication of a clear framework of expectations, review, and consequences, with ongoing monitoring, clear performance expectations, and timely feedback, can reduce late surgeon arrival and improve FCOTS. Direct and timely communication provided immediate feedback to late surgeons and indicated reporting errors, providing more accurate data on late starts. Consistent policy enforcement is critical for credibility.

Abstract:
Background Anesthesia groups may wish to decrease the supervision ratio for nontrainee providers. Because hospitals offer many first-case starts and focus on starting these cases on time, the number of anesthesiologists needed is sensitive to this ratio. The number of operating rooms that an anesthesiologist can supervise concurrently is determined by the probability of multiple simultaneous critical portions of cases (i.e., requiring presence) and the availability of cross-coverage. A simulation study showed peak occurrence of critical portions during first cases, and frequent supervision lapses. These predictions were tested using real data from an anesthesia information management system. Methods The timing and duration of critical portions of cases were determined from 1 yr of data at a tertiary care hospital. The percentages of days with at least one supervision lapse occurring at supervision ratios between 1:1 and 1:3 were determined. Results Even at a supervision ratio of 1:2, lapses occurred on 35% of days (lower 95% confidence limit = 30%). The peak incidence occurred before 8:00 AM, P &amp;lt; 0.0001 for the hypothesis that most (i.e., &amp;gt;50%) lapses occurred before this time. The average time from operating room entry until ready for prepping and draping (i.e., anesthesia release time) during first case starts was 22.2 min (95% confidence interval 21.8-22.8 min). Conclusions Decreasing the supervision ratio from 1:2 to 1:3 has a large effect on supervision lapses during first-case starts. To mitigate such lapses, either staggered starts or additional anesthesiologists working at the start of the day would be required.

Abstract:
<strong>Abstract</strong> <strong>Background:</strong> On-time start of the operating room (OR) is a good quality indicator to measure the OR efficiency. Delay in starting the first case on time has so many repercussions not only on the hospital&rsquo;s reputation, it also causes significant dissatisfactions for both patient and healthcare worker. We observed a significant delay in starting the first case on time, so we decided to undertake a quality improvement project to analyse the root causes and address them through a multidisciplinary team effort. We aimed to increase first-case on-time starts in the OR by at least 90% on-time start of the first case. <strong>Method:</strong> A multidisciplinary task force is created. Six Sigma quality improvement tool, namely DMAIC (Define, Measure, Analysed, Improvement and Control) was used to identify and causes of delays and apply constructive interventions to address those issues to maximise the on-time start of the first case of the day. The following constructive interventions were initiated OR booking process- streamlined, Perioperative nurse Facilitator, Notification to the surgeons, OR set up, Role of the Ward nurse emphasised, Preoperative nurse, OR staff counselling and training, Insurance and other support staff training. <strong>Results:</strong> We identified the factors for delays and categorised them into 7 main groups, namely patient related, surgeons related, anaesthetist related, nurse or other staffs related, process related (preop assessment, investigation, pending consultation, insurance, bed availability), Premedication/antibiotic related and others miscellaneous. We analysed total of 1340 first case performed during July 2021 to December 2022 (675 in pre-intervention and rest in post-intervention phase) of which 274 (60.8%) cases were start on time in the pre-intervention phase whereas in the post-intervention phase the percentage gradually improved to 90%. (606 on time out of 674 first cases). The mean delay in minutes for starting the first case on time was also higher in the pre-intervention group (28.6 minutes) which was gradually reduced to 17.5 minutes at the final phase of our analysis. <strong>Conclusion: </strong>A multidisciplinary team approach can identify the factors for delay in starting first case on time and the delays can be significantly improved by quality improvement tool.

Abstract:
The Watts–Strogatz networks are important models that interpolate between regular lattices and random graphs, and Barabási–Albert networks are famous models that explain the origin of the scale-free networks. Here, we consider the first encounters between two particles (e.g., prey A and predator B) embedded in the Watts–Strogatz networks and the Barabási–Albert networks. We address numerically the mean first-encounter time (MFET) while the two particles are moving and the mean first-passage time (MFPT) while the prey is fixed, aiming at uncovering the impact of the prey’s motion on the encounter time, and the conditions where the motion of the prey would accelerate (or slow) the encounter between the two particles. Different initial conditions are considered. In the case where the two particles start independently from sites that are selected randomly from the stationary distribution, on the Barabási–Albert networks, the MFET is far less than the MFPT, and the impact of prey’s motion on the encounter time is enormous, whereas, on the Watts–Strogatz networks (including Erdős-Rényi random networks), the MFET is about 0.5–1 times the MFPT, and the impact of prey’s motion on the encounter time is relatively small. We also consider the case where prey A starts from a fixed site and the predator starts from a randomly drawn site and present the conditions where the motion of the prey would accelerate (or slow) the encounter between the two particles. The relation between the MFET (or MFPT) and the average path length is also discussed.

Abstract:
Abstract Background Closed-loop communication is essential for managing a diverse surgical team. When new or unfamiliar members are present, as is common in shift-based perioperative care, challenges to effective communication can arise. Methods We introduced the Surgical Flight Plan (SFP), a novel communication tool that informs surgical team members on procedural details in advance of surgery, at our tertiary academic center. The tool was made available in the electronic health record prior to surgery. The primary outcome assessed after application of the SFP was “patient-in-room to incision time.” The secondary outcome was “improvement of communication in surgical teams” as assessed by a standardized (10-item) preintervention survey and a follow-up postintervention survey, given 3 months later. Data were gathered using Redcap software and statistical analysis was performed using SAS 9.4, significance was set at p-value less than 0.05 Results Thirty-six first-start, operative plastic surgery cases were included for the analysis (20 pre- and 16 postintervention). The average time from patient-in-room to surgical time out were 59.15 and 48.69 minutes pre-/postintervention respectively (p &lt; .0437). Sixty-one members of the surgical team responded to the survey, with the majority citing improved team communication. Conclusion The SFP significantly improved first case on-time starts (FCOTS) and may improve surgical team communication, efficiency, safety, and overall patient care. Expanding the use of the instrument into other surgical specialties is needed to further validate its efficacy.

Abstract Introduction Little is known about the time course for youth adjusting to and achieving optimal PAP adherence. Methods This retrospective study identified 12-month PAP trajectories and treatment persistence following treatment initiation in youth. Participants were first-time PAP initiators receiving care at Cincinnati Children’s Hospital from 07/2017-12/2019. Electronic downloads provided monthly PAP use. Adherence indicators were frequency (percentage of nights PAP used each month) and duration of use (average usage hours on nights used each month). Persistence of group-level adherence (frequency and duration) was measured via descriptive statistics in SPSS. Adherence sub-groups were identified using longitudinal mixed models in MPlus. Results The sample was 169 youth ages 2-22yrs started on PAP. Within the first month, 55% of participants were using PAP &amp;gt;50% of nights and 43% were using for &amp;gt;4 hours/night. Adherence (frequency and duration, respectively) decreased by month as follows: month 3 - 48% and 42%; month 6 - 41% and 41%; month 12 - 36% and 32%. Longitudinal mixed models identified 5 trajectories for frequency of use (based on the model of best fit using BIC index): “starts high, stays high” (34% of sample); “starts high, slowly decreasing” (7%); “starts high, rapidly decreasing” (12%); “starts low, slowly increasing” (8%); “starts low, stays low” (39%). Two trajectories were identified for duration (average hours worn on nights used, also based on model of best fit) and included: “starts high, slowly increasing” (40%) and “starts low, stays low” (60%). Conclusion At the group level, PAP adherence was sub-optimal in the first month of use (around half of participants using PAP &amp;gt;50% of nights or for &amp;gt;4 hours) and declined over the subsequent 11 months. However, mixed models identified distinct adherence subgroups, with about 40% of the sample falling into subgroups with relatively high adherence by month 12. This suggests acclimation to PAP takes time in a pediatric population. Findings may help clinicians/policy makers set realistic expectations around time to achieve optimal PAP adherence among youth, and highlights the need for further PAP adherence promotion interventions.

Abstract:
In this project, low-salinity water flooding has been modeled on ECLIPSE black oil simulator in three cases for a total field production life of twenty-five years. In the first case, low-salinity water flooding starts fifteen years after secondary water flooding. For the second case, low-salinity water flooding starts five years after secondary water flooding and runs till the end of the field production life. For the third case, low-salinity water flooding starts five years after secondary water flooding, but low-salinity water flooding is injected in measured pore volumes for a short period of time; then, high-salinity water flooding was resumed till the end of the field production life. This was done to measure the effect of low-salinity water flooding as slug injection. From the three cases presented, oil recovery efficiency, field oil production rate, and field water cut were observed. Increased percentages of 22.66%, 35.12%, and 26.77% were observed in the three cases, respectively.

Language acquisition is a process which can take place at any period of one's life. In the sense of first language acquisition, however, it refers to the acquisition (unconscious learning) of one's native language (or languages in the case of bilinguals) during the first 6 or 7 years of one's life (roughly from birth to the time one starts school).Language acquisition planning has a significant correlation to the language acquisition by the students. Because the students’ age in between zero up to five years is the appropriate moment to acquire a certain language.

At the end of a vacation, either customers are present, and the server starts serving the first customer, or he is idle, and he takes a vacation. The case p = 1, called the GI/G/1/V queue, was studied analytically by Gelenbe and Iasnogorodski [3] (see also [4]) and then by Doshi [1] and Fricker [2] who obtained stochastic decomposition results on the waiting-time of the nth customer extending the law decomposition result of [3]. Keilson and Servi [5] give a more complete analytic method of treating both the GI/G/1/V model and the Bernoulli vacation model: instead of the waiting time, they use a bivariate process at the service and vacation initiation epochs and the waiting-time distribution is computed as a conditional distribution of the above.

Abstract:
Gastrointestinal stromal tumor (GIST) is a rare sarcoma, typically starts in the cells that line the gastrointestinal tract’s (GIT) wall. While certain GISTs may develop slowly over time, others might spread drastically. However, it will indicate recurrence for certain people. Patients with locally resectable gastro intestinal stromal tumours continue to be treated primarily with radical surgery, which, in more than 50% of instances, results in a long-term remission of this disease. The first targeted medication for the GISTs treatment was the tyrosine kinase inhibitor imatinib, and is now the preferred option for treating advanced gastro intestinal stromal tumours. This case highlights recurrence of GIST for two times even after laparotomy which provides an information, that the hazards associated with this type of tumour must be reduced by receiving appropriate therapy because it can recur.

Abstract:
Summary Case records and radiographs of 155 horses with third carpal bone (C3) slab fractures were reviewed. Of these cases, race records were obtained for 72 Thoroughbreds and 61 Standardbreds. Three performance criteria were examined: ability to make 1 start, ability to make 10 starts or earn &gt; $2,000 (within 1 year of first start after the fracture), and earnings per start. Treatment distribution (lag screw fixation, fragment excision, or rest) was similar in both breeds. Significant differences between breeds were identified in age and sex distributions, fracture displacement, and postinjury performance. In Thoroughbreds, there was a tendency for fractures to occur in the right C3 (59%); in Standardbreds, forelimbs were affected equally. The dorsomedial aspect of C3 was the site of fracture in 87% (135/155) of the cases. Horses referred for treatment were predominantly 2-year-old Standardbreds and 3-year-old Thoroughbreds. Females of both breeds were less likely to race after injury than males (46 vs 90%). In Standardbreds, all 38 horses with racing starts before fracture were able to race again. Prior racing starts were not related to outcome in Thoroughbreds. The effects of treatment on outcome were not significantly different. Fracture characteristics did not significantly affect outcome, but did influence treatment selection. Convalescent time was not correlated with any of the variables examined (including treatment) or related to outcome; time from admission to first start averaged 11 months. In Standardbreds, 77% of the horses with C3 slab fracture raced after injury; in Thoroughbreds, 65% raced. Earnings per start declined in each breed, but the decline was more pronounced in Thoroughbreds.

Abstract:
Introduction Goodpasture's syndrome is a rare, autoimmune disease characterized by pulmonary hemorrhage, glomerulonephritis and production of anti-GBM (glomerular basement membrane) antibodies. The etiology of this syndrome is still unknown. Goodpasture's syndrome usually starts with pulmonary hemorrhage, which is followed by symptoms of kidney disease. Laboratory findings often include: anemia, microhematuria, proteinuria, increased levels of urea and creatinine and anti-GBM antibodies. Diagnosis of this syndrome can be established by presence of pulmonary hemorrhage, pulmonary radiography, kidney biopsy and positive result of circulating anti-GBM antibodies. Treatment of this syndrome should be initiated as soon as possible using a combination of cortocosteroids, cytostatics and plasmapheresis. Case report The first symptoms in a nineteen-year-old female patient were caused by anemia. Two months later she reported symptoms of pulmonary hemorrhage. At that point of time she already had renal insufficiency and was immediately hospitalized. The same day we started therapy with cortocosteroids, endoxan and plasmapheresis was initiated. Recovery of pulmonary function was obtained, but kidney function was lost. Discussion and Conclusions The most important thing in regard to Goodpasture's syndrome is quick diagnosis. Because of that, if patients report any kind of pulmonary hemorrhage, this syndrome must be considered. At that point of time, kidney function is usually not irreversibly damaged. The second important thing in Goodpasture's syndrome is that treatment must be very aggressive using a combination of immunosuppressives and plasmapheresis. This is the only chance for these patients to avoid hemodialysis or death.

Abstract:
This paper develops an inventory model for items with uncertain deterioration rate, time-dependent demand rate with nonincreasing function, and allowable shortage under fuzzy inflationary situation. The goods are not deteriorating upon reception, but the deteriorating starts after elapsing a specified time. The lead time and inflation rate are both uncertain in the model. The resultant effect of inflation and time value of money is assumed to be fuzzy in nature and also we consider lead time as a fuzzy function of order quantity. Furthermore the following different deterioration rates have been considered: for the first case we consider fuzzy deterioration rate and for the second case we assume that the deterioration rate is time dependent and follows Weibull distribution with three known parameters. Since the inflation rate, deterioration rate, and the lead time are fuzzy numbers, the objective function becomes fuzzy. Therefore the estimate of total costs for each case is derived using signed distance technique for defuzzification. The optimal replenishment policy for the model is to minimize the total present value of inventory system costs, derived for both the above mentioned policies. Numerical examples are then presented to illustrate how the proposed model is applied.

The main goal of the Higher Education is giving good knowledge to students. High level of theoretical knowledge makes the young specialist competitive in society. After 1 year he starts to use his practice skills. The students of medical faculties haven’t time for mistakes. The first-year residency program General practitioner assumes that the young doctor is leaving for the periphery and is starting practical work. Therefore, one of the priorities of the medical university is preparing medical students with practical skills. How can we achieve this? Only by using a case–study, for better learning and receiving practical skills.

Abstract:
The use of fiber-optic communication lines allows for the transfer of huge amounts of information per unit of time. Even short-term failures significantly affect the quality of services provided. The level of network reliability depends on how resilient the network infrastructure is to failures and how quickly recovery occurs after them. Reliability guarantees are the main component of quality of service agreements between operators and consumers. Most often, redundancy is used to ensure the required level of reliability indicators. The disadvantage of this approach is the high cost of network bandwidth, the advantage - is a short time to switch at the reserve after a failure is detected. In order to reduce costs, in some cases, the 1:N backup option is used (one backup path is allocated for N working paths). In this paper, we consider the case of 1:2, when one backup path is allocated for two working paths. In this case active and passive switching modes are possible. When switching is active, if both working paths fail, the traffic of one of them switches to the backup path. After restoring the working path, traffic switches to the restored path, i.e. the backup path is freed. It is replaced by traffic from another failed path. A special feature of passive mode consists in that after the backup path is released, it does not deal with the traffic of the second failed path. There are several ways to restore traffic over a failed work path:. the second working path starts to recover after the first one is restored; the second working path starts to recover simultaneously with the first one. In either case, the traffic of the first path is switched back from the backup to the working path after it is restored. This paper presents a method for calculating the conditional probability that the backup path will be used for transmitting traffic from one of the working paths if both paths fail. The formula for calculating the unavailability factor of working paths is given.

Abstract:
The question of determining the time of committing a tax crime is quite complex both in theory and in practice. Dispositions of articles on evasion of taxes, fees and insurance premiums indicate a mandatory feature of the objective side – the failure to submit mandatory documents; the doctrine and law enforcement practice are guided by the fact that it is criminal to fail to pay mandatory payments, and not the fact of an unsubstantiated declaration (other mandatory documents), therefore, the time of committing a tax crime is the failure to receive funds to the budget. The situation is complicated by the fact that the doctrine of criminal law lacks a unified approach to under-standing whether to consider tax crimes as continuing or c ongoing. In the article the resolution of this question: if the taxpayer submits a false Declaration within three years, his act should be regarded as the offense continued in the case of non-Declaration of the actions of the taxpayer should be regarded as a continuing offence, which starts with the date of the first unpaid and ends as a result of restraint by law enforcement or the occurrence of other events that prevent the further continuation.

Abstract:
Queuing analysis on check-in counter in airport is required to accommodate the passenger processing facilities, such as check-in service. The purpose of this paper is to evaluate the performance of a queuing system at check-in facilities in 2nd passenger terminal Lombok Praya International Airport in 2016 and 2036. This analysis is done by determining parameters of the queues at every check-in counter through simulations on Viswalk. Before running the simulation, the model of airport terminal must be created first. Queuing simulation starts with the traffic demand forecasting of domestic departure passenger for the next 20 years. To determine the optimal number of check-in counters, an iteration of various number is performed. Check-in services time data were adopted from previous study which became an input of the simulation using two different scenarios. The expected output are the queuing parameter and the distribution of passenger service time at each check-in counter.

Full text
Abstract:
This article starts with the observation that a sociological analysis of interactions concerning drugs cannot rely on accounts of drugs that were generated in the field because these accounts (such as the distinction between drugs and non-drugs or between intended effects and side effects) are shaped by strong interests. The article suggests two approaches to obtaining actor-independent accounts, both of which are based on comparisons. The first approach is a symmetrization of perspectives, which can be achieved by including the perspectives of as many different actors as possible as well as the abstract actors of science and law. The second approach starts from the definition of a problem that is contingent but grounded in practices of the field. In the case of drugs, this problem can be constructed as how laypersons can rate the identity and quality of specific things as unproblematic. In both cases, an ontological idea of the “drug as such” is replaced by a social-constructivist view of the drug, which at the same time takes the drug's materiality into account.

Abstract:
We analyze, for the first time, the first-digit distribution of the monkeypox daily cases in the United States of America, from May 17 to September 21, 2022. The overall data follow Benford’s law, a conclusion substantiated by eight different statistical tests, including the “Euclidean distance test”, which has been designed to specifically check Benford’s distribution in data. This result aligns with those of other infectious diseases, such as COVID 19, whose Benfordness has already been confirmed in the literature. Daily counts of monkeypox cases, like any other disease evolve in time. For this reason, we analyzed the temporal deviation of monkeypox counts from Benford’s law to check for possible anomalies in the temporal series of cases. The dynamic analysis was performed by means of the Euclidean distance test. This is because, to our best knowledge, that is the only statistically valid, Benford-specific test whose underlying estimator has a cumulative distribution function with known analytical properties, and is applicable to small and large samples. This is the case in dynamic analyses, where the number of data points usually starts from small values and then increases in time. No anomalies were detected, which indicates that no (fraudulent) alterations or errors in data gathering took place.

Full text
Abstract:
In the case of the widespread adoption of electric vehicles (EV), it is well known that their use and charging could affect the network distribution system, with possible repercussions including line overload and transformer saturation. In consequence, during periods of peak energy demand, the number of EVs that can be simultaneously charged, or their individual power consumption, should be controlled, particularly if the production of energy relies solely on renewable sources. This requires the adoption of adaptive and/or intelligent charging strategies. This paper focuses on public charging stations and proposes methods of attribution of charging priority based on the level of charge required and premiums. The proposed solution is based on model predictive control (MPC), which maintains total current/power within limits (which can change with time) and imparts real-time priority charge scheduling of multiple charging bays. The priority is defined in the diagonal entry of the quadratic form matrix of the cost function. In all simulations, the order of EV charging operation matched the attributed priorities for the cases of ten cars within the available power. If two or more EVs possess similar or equal diagonal entry values, then the car with the smallest battery capacitance starts to charge its battery first. The method is also shown to readily allow participation in Demand Side Response (DSR) schemes by reducing the current temporarily during the charging operation.

Abstract:
Purpose – The innovation success requires a deep understanding of risks and benefits of the process, as well as of the best moment for innovating. The purpose of this paper is to explore the current retailers’ choice of innovating in terms of being the first innovator imitating competitors’ innovations, by declining the benefits and risks associated with the both strategies. Design/methodology/approach – Building on qualitative data from retail industry, with emphasis on fashion (including clothes, jewelry, and accessories), the investigation provides an empirical contribution to the emerging area on innovation management in retailing through its in-depth investigation of the strategies of eight case retailers who introduced technological innovations in the last three years, and by mapping the patterns between strategy and outcomes. Findings – The analysis revealed how pioneers and followers acted their strategies for achieving benefits and reducing the encountered risks. In particular, findings identify to what extend pioneers act according the technology push and followers according to the demand pull. Originality/value – The research starts from the definition of the time choice of innovating, and the subsequent choice of being the first innovation adopter or the imitator. The insights support scholarly exploration of innovation management by offering a new marketing management perspective, and providing practitioners with a better understanding on the time choice for innovating in retailing and also in broader empirical settings.

Abstract:
Background: First start delays in the operating room have a downstream effect on operating room efficiency and patient satisfaction. In accordance with the American Recovery and Reinvestment Act, in February 2014, our institution adopted EPICTM as our electronic health record (EHR). The impact of the transition from paper to electronic documentation on operating room efficiency is not known. This study analyzed first start data as a measure of overall operative suite efficiency, looking at the initial impact and the learning curve to return to baseline parameters.Methods: A retrospective review of on time start data was reviewed for three months prior and 4 months after implementation of the EHR. A start was considered delayed if the patient arrived to the room after the 7:30 start time. Patients transported from the intensive care unit were excluded from analysis. Data was analyzed using control charts for the percentages and comparison of means using Dunnet’s methods. Confidence intervals were calculated at .05 and .01 for significance.Results: After EPIC implementation, there was an initial drop in on time starts from over 60% to 41% followed by gradual return to pre-implementation level within 4 months (p &lt; .01).Conclusions: Implementation of an EHR produced decreased efficiency in on time first starts in the operative suite, but the learning curve was brief, returning to baseline values in 4 months. These findings can serve as a guide for other institutions that are undergoing transition from a paper to an electronic medical record.

Abstract:
e17556 Background: The Affordable Care Act (ACA) introduced a pay for performance model focused on: safety, timeliness, effectiveness, efficiency, patient-centered, equitable care. COH is an NCI sponsored Comprehensive Cancer Center, focused on cancer care. Methods: In 2011, a physician led team with representation from finance, QRRM, nursing and legal identified 13 quality measures (QM) where opportunities for improvement (OFI) existed. Selection criteria included measurability, importance, applicability to ACA, physician impact, return on investment and national importance. The QM include HCAHPS score, Healthcare Associated Infection rate (HAI), quantity of blood products internally produced (BP), coder response rate (RR), use of sepsis bundle orders, time to new patient appointments (NPA), OR 1st case on-time starts, timeliness of adjuvant therapy for breast/colon cancer patients, SCIP composite score and use of VTE prophylaxis orders. HCP for the first 4 QM was assessed based upon institutional performance; 6 QM were assessed upon departmental performance. There were 3 build measures (BM): creating a system to obtain advanced directives (AD) on all new patients, creating a system for effective communication with referring physicians and 4 departmental BM based on best practices. Results: PEP performance was assessed between 5/1/12-12/31/12. 174 physicians in 11 departments were eligible for a $2.05 million incentive pool. QM were evaluated using a tiered bonus structure. Significant improvements were seen in HAI, BP production, SCIP, OR starts and timely adjuvant therapy. There were improvements in the use of VTE orders, but aggregate performance fell below payment threshold. The build measure for AD was completed. Conclusions: (1) PEP is an effective tool for physician engagement in an academic medical center. (2) PEP enhanced alignment between the medical group, hospital, nursing and administration. (3) PEP was effective in improving HCP in less than one year from its inception. [Table: see text]

Abstract:
ABSTRACT This case is based on a series of actual events in a local homeowners' association (HOA). Instructors teaching fraud detection in their courses often use historical cases in which the “answer” to whether fraud has been committed is known. This case is unique because it is based on real incidents that occurred in an HOA. The case starts with the inception of the HOA up to the present, at which time the situation is still evolving. Students are required to recognize the conditions that increase the potential for fraudulent activity in an organization. Then they must analyze the activities in this particular association to identify the “red flags” that indicate that fraudulent activity could occur. Finally, students must develop recommendations to mitigate the identified risk areas. After completing this case, students will be more aware of potential and actual incidents of fraudulent activity and be able to address how these incidents can be prevented. This knowledge will benefit them in any area of accounting they choose to pursue. This case can be used in fraud examination, auditing, accounting information systems, and financial accounting classes. Data Availability: Data available from first author.

Abstract:
We study the problem of scheduling random energy demands within a fixed normalized time horizon. Each demand has to be serviced without interruption at a constant intensity, while its duration is bounded by a pair of malleability constraints. Such constraints are assumed to be characterized by an i.i.d random vector that follows a general distribution. At each time instance, the total power consumption is computed as the sum of the intensities of all demands being serviced at that moment. Our objective is to minimize both the maximum and the total convex cost of the power consumption of the grid. The problem is considered in the asymptotic regime. In this regime, the number of demands is assumed to be large, and their (random) energy requirements are inversely proportional to the number of demands. Such setting allows us to introduce a linear-time scheduling policy and shows its asymptotic optimality with respect to both cost criteria. We first study the optimization problem in the case where all demands are available a priori, i.e., before scheduling starts. Then we extend our approach for the case of demand scheduling in an arbitrary length time horizon, where the demands arrive randomly during this time interval.

Abstract:
Elongated, bar-like galaxies without a significant disk component, with little rotation support and no gas, often form as a result of tidal interactions with a galaxy cluster, as was recently demonstrated using the IllustrisTNG-100 simulation. Galaxies that exhibit similar properties are, however, also found to be infalling into the cluster for the first time. We use the same simulation to study in detail the history of such a galaxy over cosmic time in order to determine its origin. The bar appears to be triggered at t = 6.8 Gyr by the combined effect of the last significant merger with a subhalo and the first passage of another dwarf satellite, both ten times less massive than the galaxy. The satellites deposit all their gas in the galaxy, contributing to its third and last star-formation episode, which perturbs the disk and may also contribute to the formation of the bar. The galaxy then starts to lose its gas and dark matter due to its passage near a group of more massive galaxies. The strongest interaction involves a galaxy 22 times more massive, leaving the barred galaxy with no gas and half of its maximum dark matter mass. During this time, the bar grows steadily, seemingly unaffected by the interactions, although they may have aided its growth by stripping the gas. The studied galaxy, together with two other similar objects briefly discussed in this Letter, suggest the existence of a new class of early-type barred galaxies and thereby demonstrate the importance of interactions in galaxy formation and evolution.

This paper studies on the struggle and undertakings of Dr Taaita Toweett towards the achievement of independence of Kenya from 1958 to 1964. The paper starts by ventilating on the background of Toweett from childhood to the time he plunged to politics in 1958. The paper focuses on two objectives, namely, the emergency of Taaita Toweett in to active politics and his contribution and legacies of Toweett towards achievement of independence. The paper uses the great man theory postulated by great historian Thomas Carlyle. The theory describes the influence of the leaders like Napoleon and Shakespeare in ancient societies thus applicable in the analysis of Toweett activities in the straddle for independence in Kenya. Qualitative methodology and historical technique were used in data collection while historian research design and purposive sampling were the main techniques used to identify the oral informants. Archival information was also a source of written data collected. The main themes which guided this research paper are the emergence of Toweett into active politics in 1957, the first Lancaster House conference of 1960, the formation of National political parties and the second Lancaster House conference of 1962.

Abstract:
Here, we studied Bianchi type-III string cosmological models generated using a cloud of strings with particles connected to them in the framework of Lyra geometry considering five-dimensional spacetime. We assume that the shear scalar and scalar expansion are proportional to obtain the exact solutions of the survival field equations here. Secondly, we adopt the assumption considering the Reddy string condition. From the different cases obtained here, the first case gives the Bianchi type-III string cosmology in Lyra geometry in five-dimensional spacetime, and the second case gives the five-dimensional vacuum model in general relativity. The various parameters of the model universe, which are very important for the description of the Universe, are obtained, and their properties are studied and compared with the recent observational findings. The model universe obtained here starts with the Big Bang, and as time progresses, both particle density and energy density decrease with the expansion of our Universe.

Abstract:
Abstract We consider the problem of the first passage time to the origin of a spatially non-homogeneous random walk (RW) with a position-dependent drift, known as the Gillis random walk, in the presence of resetting. The walk starts from an initial site x 0 and, with fixed probability r, at each step may be relocated to a given site x r . From a general perspective, we first derive a series of results regarding the first and the second moment of the first hitting time distribution, valid for a wide class of processes, including RWs lacking the property of translational invariance; we then apply these results to the specific model. When resetting is not applied, by tuning the value of a parameter which defines the transition probability of the process, denoted by ε, the recurrence properties of the walk are changed, and we can observe: a transient walk, a null-recurrent walk, or a positive-recurrent walk. When the resetting mechanism is switched on, we study quantitatively in all regimes the improvement of the search efficiency. In particular, in every case resetting allows the system to reach the target with probability one and, on average, in a finite time. If the reset-free system is in the transient or null-recurrent regime, this makes resetting always advantageous and moreover, it assures the existence of an optimal resetting probability r ∗ which minimizes the mean first hitting time. Instead, when the system is positive-recurrent, the introduction of resetting is not necessarily beneficial. We explain that in this case there exists a threshold r t h for the resetting probability r, above which the resetting mechanism yields a larger mean first hitting time with respect to the reset-free system. We provide a study of r t h , which can be zero for some values of the system parameters, meaning that resetting cannot be beneficial in those situations. All the theoretical findings are corroborated with numerical simulations.
