Batting Performance

The purpose of this paper is to present a summary of batting and bowling performance measures that have been developed over a period of eight years. The measure of batting performance (BP) consists of three components. Firstly, an exponentially weighted average (EWA) is calculated in which recent scores have higher weights than scores further back in time in order to get a measure that adequately reflects the batsman’s present form. EWA is then adjusted up- or downwards depending on the batsman’s consistency and strike rate. This measure was subsequently generalized to BPW which includes weights for runs scored against specific countries in home or away matches separately. In the case of bowling, the first challenge was to develop a single comprehensive measure of bowling performance, the combined bowling rate (CBR) for limited overs matches and the dynamic bowling rate (DBR) for unlimited overs matches. Hence, by alsotaking bowling consistency into account, the current bowling performance measure (CBP) wasdeveloped. This measure was also extended to include weights for wickets taken and runs concededagainst each international team in home or away matches. These measures contain parametersthat were based on players’ scores up to the specific date of calculation. Before using the latestavailable data for the present presentation, it is logical to update these parameters. This hasbeen done in the present study. If a player performs well at local level, it is important to be ableto compare his performance with those of players already in the national team. Weights havebeen determined for runs scored by batsmen and also for runs conceded and wickets taken bybowlers in local matches, whereby the performances of players can be compared irrespective ofthe proportion of international matches played by each player. After having used the measures onvarious occasions the need arose to revise some of them slightly. The updated measures are thenused to give rankings of South African batsmen and bowlers in First Class and List A matchesalike. Methods have also been developed to compare the batting and bowling performances ofplayers after a short series of matches. It was shown that the traditional average could haveunrealistic values in the case of a batsman who had a large percentage of not out scores in ashort series. Alternative measures have been developed and shown to give much more realisticvalues. In the case of bowling it is important not only to count the number of wickets a bowlerhas taken, but to distinguish between the wickets of top and middle order batsmen on the onehand and lower order batsmen on the other. A system has been established whereby weights areattached to the wickets according to the batting position of the batsman. Instead of just countingthe number of wickets taken, the sum of the weights of the wickets taken by the bowler is usedin the calculation of CBR* or DBR*. Finally, the latest form of the game, Twenty20 cricket, isalso discussed.

Similarity And Difference

Performance-measure weights for incentive compensation are often determined subjectively. Determining these weights is a cognitively difficult task, and archival research shows that observed performance-measure weights are only partially consistent with the predictions of agency theory. Ittner et al. (2003) have concluded that psychology theory can help to explain such inconsistencies. In an experimental setting based on Feltham and Xie (1994), we use psychology theories of reasoning to predict distinctive patterns of similarity and difference between optimal and actual subjective performance-measure weights. The following predictions are supported. First, in contrast to a number of prior studies, most individuals' decisions are significantly influenced by the performance measures' error variance (precision) and error covariance. Second, directional errors in the use of these measurement attributes are relatively frequent, resulting in a mean underreaction to an accounting change that alters performance measurement error. Third, individuals seem insufficiently aware that a change in the accounting for one measure has spillover effects on the optimal weighting of the other measure in a two-measure incentive system. In consequence, they make performance-measure weighting decisions that are likely to result in misallocations of agent effort.

ABSTRACT This paper empirically examines the interactive effect of competition intensity and competition type on the use of customer satisfaction measures in executives' annual bonus contracts. Specifically, we predict a stronger association between competition intensity in an industry and the use of customer satisfaction measures in executives' annual bonus contracts when the competition is non-price-based than when the competition is price-based. Using hand-collected data from Standard & Poor's (S&P) 1500 firms' disclosures of the use of customer satisfaction measures in executive bonus contracts in 2006 and 2010 proxy statements, we find results consistent with our prediction. Our results are robust to alternative measures of competition type and competition intensity. We also find similar results when we use the weight on customer satisfaction measures in executive bonus contracts as the dependent variable. Our study extends the literature on the effect of competition on the design of managerial incentives by distinguishing between competition intensity and competition type, and providing the first large-sample empirical evidence on the joint effect of these two dimensions of competition on the incentive use of an important nonfinancial performance measure. Data Availability: Data used in this study are obtained from publicly available sources.

And Performance

Background and Purpose The literature demonstrates how utilizing evidence-based, standardized stroke care can improve patient outcomes; however, the contribution of electronic medical record (EMR) systems may also impact outcomes by ensuring utilization and compliance with established stroke performance measures, facilitating and improving documentation requirements, and standardizing approach to care. In 2008, documentation in patients’ medical records was done in combination of paper and a template free EMR. Originally, the EMR was used for order entry, then transitioned to full electronic documentation in 2009. At that time we implemented our stroke templates and performance measures based on regulatory standards. We hypothesized that the stroke template implementation would help us achieve performance measure criteria above state benchmarks as set out by the New York State Department of Health (NYS DOH). Methods Implementation was phased in [over 18 months], initially using a template that only included neurological assessment and free text fields for stroke measures. By July 2010, existing templates were modified and additional stroke templates were implemented to meet new regulatory requirements and meaningful use criteria. Retrospective data review was conducted for performance comparison between 2008 -- one year prior to EMR/template implementation -- and 2010. In Quarter 1 of 2011 EMR was also implemented in the Emergency Department (ED). Data was reviewed for compliance with stroke measures. Results Documentation compliance substantially improved between 2008 and Quarter 1 2011: Compliance for these measures has been maintained ≥ 85% since November 2010, ≥ 90% Q1 2011 Conclusions The EMR implementation of stroke templates and performance measures can produce substantial improvement in performance measure compliance. Future steps will include automated documentation alerts to retrieve information and real time discovery of missing documentation for concurrent quality review and improvement

The application of the receiver operating characteristic (ROC) curve for computer-aided diagnostic systems is reviewed. A statistical framework is presented and different methods of evaluating the classification performance of computer-aided diagnostic systems, and, in particular, systems for ultrasonic tissue characterization, are derived. Most classifiers that are used today are dependent on a separation threshold, which can be chosen freely in many cases. The separation threshold separates the range of output values of the classification system into different target groups, thus conducting the actual classification process. In the first part of this paper, threshold specific performance measures, e.g., sensitivity and specificity; are presented. In the second part, a threshold-independent performance measure, the area under the ROC curve, is reviewed. Only the use of separation threshold-independent performance measures provides classification results that are overall representative for computer-aided diagnostic systems. The following text was motivated by the lack of a complete and definite discussion of the underlying subject in available textbooks, references and publications. Most manuscripts published so far address the theme of performance evaluation using ROC analysis in a manner too general to be practical for everyday use in the development of computer-aided diagnostic systems. Nowadays, the user of computer-aided diagnostic systems typically handles huge amounts of numerical data, not always distributed normally. Many assumptions made in more or less theoretical works on ROC analysis are no longer valid for real-life data. The paper aims at closing the gap between theoretical works and real-life data. The review provides the interested scientist with information needed to conduct ROC analysis and to integrate algorithms performing ROC analysis into classification systems while understanding the basic principles of classification.

Teacher Learning Communities

In the Integrated Strategic Planning Framework for Teacher Education and Development, a South African policy, the Department of Basic Education (DBE) and the Department of Higher Education (DHET) call for the formation of professional learning communities and envisage support for teachers and access to enhanced professional development opportunities at the local level. However, the formation and operation of professional learning communities in a South African context is still unclear. In this article we use the concept of professional learning communities to examine the extent to which 2 teacher learning communities operate as professional learning communities. We used interviews, observations, survey questionnaires and document analysis to generate data. The findings of the study reveal that the 2 teacher learning communities were initiated by the DBE and not by teachers. However, the size of 1 teacher learning community and the nature of its functioning seemed to adhere to the characteristics of a professional learning community while the other did not. The findings indicate that professional learning communities that operate in developing contexts might be functional when all the stakeholders play a meaningful role in supporting professional learning communities.

The objective of this research was to determine if three alternative shoe upper closures improve biomechanical performance measures relative to a standard lace closure in court-based movements. NCAA Division 1 and club-level male athletes recruited from lacrosse, soccer, tennis, and rugby performed four court-based movements: Lateral Skater Jump repeats (LSJ), Countermovement Jump repeats (CMJ), Triangle Drop Step drill (TDS), and Anterior-Posterior drill (AP). Each athlete performed the movements in four shoe upper closures: Standard Closure, Lace Replacement, Y Wrap, and Tri Strap. Ground contact time, peak eccentric rate of force development (RFD), peak concentric GRF, peak concentric COM power, eccentric work, concentric work, and movement completion time were measured. Tri Strap saw improvements in four of seven biomechanical variables during CMJ and LSJ and one variable during TDS. Lace Replacement delivered improvements in one performance measure during CMJ, LSJ, and AP, and two variables in TDS. Y Wrap improved performance in three performance measures during LSJ and impaired performance in two measures during CMJ and three measures during AP. Tri Strap provided the most consistent performance improvements across all movements. This study allowed for the mechanical properties of the shoe lower to remain consistent across designs to examine if an alternative shoe upper closure could enhance performance. Our results indicate that increased proprioception and/or mechanical properties due to the alternative closures, especially Tri Strap, improves athlete performance, which concludes that the design of the shoe upper is an essential consideration in shoe design.

Introduction: Out-of-hospital cardiac arrest (OHCA) remains a highly morbid public health problem. Despite improving practices and clear guidelines, mortality from this condition remains high at 90%, with survivors often suffering from poor neurologic outcomes. To determine the feasibility of quality improvement collaboratives to narrow gaps between evidence-based practice and patient care for OHCA, we conducted a pilot study of the AHA Resuscitation Collaborative. Methods: Eight emergency medical service agencies participated in the quality improvement collaborative pilot project. We identified several OHCA performance measures to assess the quality of care, guide collaborative activities, and monitor change in performance over time. Over the course of four learning sessions, participants were trained in quality improvement and performance measurement, analyzed performance measure results, and shared successes and challenges. Results: Five remaining agencies underwent the process outlined in Figure 1. Adherence to performance measures, including compression rate compliance (Figure 2), improved over the course of the collaborative. Compression rate compliance in Figure 2 corresponds to the process improvement efforts of the Chesapeake Fire Department with achievement of goals for optimal range of chest compression rate between 100 and 120 compressions per minute during resuscitations. Conclusion: As demonstrated in Virginia, the collaborative approach was an effective framework to improve OHCA care. Improvement in performance measures, the evident commitment of dedicated peers and colleagues, consistent collaboration, and the effective diffusion of best practices all support the continued use of this model.

ABSTRACT Teamwork and team incentives are increasingly prevalent in modern organizations. Performance measures used to evaluate individuals' contributions to teamwork are often non-verifiable. We study a principal-multi-agent model of relational (self-enforcing) contracts in which the optimal contract resembles a bonus pool. It specifies a minimum joint bonus floor the principal is required to pay out to the agents, and gives the principal discretion to use non-verifiable performance measures to both increase the size of the pool and to allocate the pool to the agents. The joint bonus floor is useful because of its role in motivating the agents to mutually monitor each other by facilitating a strategic complementarity in their payoffs. In an extension section, we introduce a verifiable team performance measure that is a noisy version of the individual non-verifiable measures, and show that the verifiable measure is either ignored or used to create a conditional bonus floor.

Using a sample of 47 Portuguese and Spanish firms for the period 2010 to 2017, the authors study the relationship between female presence on board and firm's accounting (ROA and ROE) and market-based (MTB and Tobin's Q) performance. They find that women on the board of directors is positively related to firm's performance, as well as the gender of the CFO and the proportion of women on the listed key professionals, when we consider the market measures of performance, not being so consistent for accounting performance measures. Results were sensitive to the performance measure used. The results reinforce the political options of European Commission gender established quotas, revealing that in the Iberian countries these quotas are not being effectively implemented, even if results suggest that women on board in fact exert positive influence over market performance. This also led us to think that financial markets may also react in a positive way when the CFO of the company is a woman instead of a man, despite the sample limitations both in terms of gender and number of firms.

Different Types

The author presents performance analysis of a single buffer multiple-queue system. Four different types of service disciplines (i.e., non-preemptive, pre-emptive repeat different, state dependent random polling and globally gated) are analyzed. His model includes correlated input process and three different types of non-productive time (i.e., switchover, vacation and idle time). Special cases of the model includes server with mixed multiple and single vacations, stopping server with delayed vacation and stopping server with alternating vacation and idle time. For each of the four service disciplines the key performance measures such as average customer waiting time, loss probability, and throughput are computed. The results permit a detailed discussion of how these performance measures depends on the customer arrival rate, the customer service time, the switchover time, the vacation time, and the idle time. Moreover, extensive numerical results are presented and the four service disciplines are compared with respect to the performance measure. Previous studies of the single buffer multiple-queue systems tend to provide separate analysis for the two cases of zero and nonzero switchover time. The author is able to provide a unified analysis for the two cases. His results generalize and improve a number of known results on single buffer multiple-queue systems. Furthermore, this method does not require differentiation while it is needed if one uses the probability generating function approach. Lastly, the author's approach works for all single buffer multiple-queue systems in which the next queue to be served is determines solely on the basis of the occupancy states at the end of the cycle time.
