Sir Isaac Newton Essay Papers Theory Statement: Through his initial beneficial encounters and with the information left by his ancestors, Sir Isaac Newton had the option to create math, regular powers, and optics. From birth to youth, Isaac Newton conquered numerous individual, social, and mental difficulties. It is through these encounters that made the individual society knows him as nowadays. The start of these impediments began during childbirth for Newton. Isaac was brought into the world untimely on Christmas Day 1642, in the home of Woolsthorpe, 7 miles south of Grantham in Lincolnshire. It is said that Ã¢â¬Å"Because Galileo, . . . had kicked the bucket that year, a criticalness connects itself to 1642Ã¢â¬ (Westfall 1). Despite the fact that his dad had kicked the bucket before Isaac was conceived, he was given his fatherÃ¢â¬â¢s name. He was naturally introduced to a cultivating family that had worked their route gradually up the Ã¢â¬Å"social ladderÃ¢â¬ . The NewtonÃ¢â¬â¢s were one of only a handful hardly any families to succeed in Lincolnshire (Westfall 1). At three years old IsaacÃ¢â¬â¢s life would take a radical turn. At the point when Isaac was three his mom, Hannah Ayscough, remarried to the Reverend Barnabas Smith (Internet-newtonia). Isaac and the Reverend never got along and the Reverend would not have a kid that was not his living with him. Isaac remained with his grandparents when his mom went to live with the Reverend in North Witham. His maternal grandma raised Isaac until he was ten. It is accepted that his motherÃ¢â¬â¢s second marriage and her leaving caused numerous issues for Isaac as a kid. While living with his grandparents he went to day school close by in Skillington and Stoke. Isaac was encircled by numerous cousins and other relatives in the encompassing region however, Ã¢â¬Å"He shaped no bond with any of his various family members that can be followed later in his lifeÃ¢â¬ (Westfall 11). In 1653 his mom returned after her second spouse kicked the bucket. With her she brought one relative and two stepsisters. In spite of the fact that it isn't known, sharpness may have inc urred Isaac when his three new kin showed up. Never the less, after two years at twelve years old he was sent to Grantham to go to language school. While going to language structure school Isaac lived with the pharmacist Mr. Clark (Westfall 12). Mr. Clark had three stepchildren from the main marriage of his better half, Miss Storer, who were likewise living in his home. In school and at home Isaac was obviously unique and didn't coexist with some other young men. He was regularly in battles and recalled just a single pleasant kid from school, Chrichloe. The various young men appeared to abhor him. He was increasingly agreeable in the organization of young ladies. He made doll furniture for Mr. ClarkÃ¢â¬â¢s little girl. From this IsaacÃ¢â¬â¢s first and last sentimental experience created. Ã¢â¬Å"Indeed, as the two developed more seasoned, something of a sentiment clearly created among him and Miss StorerÃ¢â¬ (Westfall 13). From doll furniture Newton proceeded onward to other l ittle machines. He utilized all the cash his mom sent him to purchase instruments and occupied his live with the machines. He began to look all starry eyed at Mr. ClarkÃ¢â¬â¢s library and would peruse as regularly as could reasonably be expected. Now and again he would invest such a great amount of energy in ventures that he would fall behind in school. At the point when he understood he was falling behind all Isaac needed to do was get his course book and would promptly be up to speed. Through his machines Newton got capable in drawing and his developments consistently turned out to be increasingly detailed. At seventeen years old in 1659, Newton left Mr. Clark and had another groundbreaking experience. At the point when Newton was seventeen his mom removed him from school and took him back to the family ranch. Attempting to show him how to run the cultivate and deal with the bequest was a disappointment. Newton would consistently pay off an employed hand to accomplish the work h e should. At the point when he should be visiting the area selling produce he would go to his old room in Mr. ClarkÃ¢â¬â¢s house and read or play with his machines. In the entirety of his extra time he came back to developing and building machines. NewtonÃ¢â¬â¢s uncle and old schoolmaster saw that he was in an inappropriate exchange and encouraged his mom to set him up to go to the University (Westfall 17). In 1660 he came back to Grantham to complete language structure school and plan for the college. In June of 1661 Newton entered Trinity College, Cambridge (Internet-gatherings). While at Cambridge Newton considered science (Internet-newtonia). This is when Newton originally began to dig into the numerous revelations he would before long be making. All through Isaac NewtonÃ¢â¬â¢s youth and early adulthood he interacted with numerous obstructions. Regardless of whether it was his mom leaving or his powerlessness to associate with his friends, Newton defeated the difficulties that confronted him. He had the option to leave the family domain and exchange behind so as to get superior training. His insight is the thing that isolated him from every other person. The capacity he appeared as a youngster was only the start. Newton made the majority of his most significant revelations Ã¢â¬ unadulterated science, hypothesis of attractive energy, and optics Ã¢â¬ before he even graduated school. In spite of the fact that he learned geometry through school, he talked about himself as self-educated. One of his soonest numerical disclosures was the binomial theorm. Ã¢â¬Å"The binomial theorm gives an equation, or rule, as Newton called it, for recording the extension of any intensity of (1+x).Ã¢â¬ (Anthony 53) A case of this is as follows:(1+x)^n = 1 + nx + n(n-1) x^2 + n(n-1)(n-2) x^3 + Ã¢â¬ ¦ nx^(n-1) + x^n1*2 1*2*3This was an early endeavor at getting separation. Ã¢â¬Å"Newton made commitments to all parts of science at that point contemplated, yet is particularly renowned for his answers for the contemporary issues in systematic geometry of attracting digressions to bends (separation) and characterizing zones limited by bends (integration).Ã¢â¬ (Hall on the web) He found that they were reverse to one another. Simultaneously, he made sense of an approach to take care of these issues with his strategy for fluxions and backwards technique for fluxions. Fluxions are worried about the rate at which the change happens. The pace of progress of an amount shows how the amount is expanding or diminishing at a given time. The possibility of Ã¢â¬Å"rate of changeÃ¢â¬ is so significant in the domain of building, where muddled changes moving happen. The territories of surfaces, and volumes of solids quite often require these techniques for their assessments, as do likewise focuses of gravity and snapshots of latency. Indeed, even the advanced investigation of streamlined features and the study of hydrodynamics would be inconceivable without the standards of the math. One of the most significant utilizations of the differential math might be found in issues including maxima and minima. Ã¢â¬Å"Now it is realized that the estimation of the differential coefficient anytime on the bend chan ges with the edge that the digression at the point makes with the hub of x. In going through a most extreme or a base, the tendency of the digression gets zero, with the goal that the pints of maxima and minima might be found by comparing the differential coefficient to zero.Ã¢â¬ (Anthony 73)By setting up these essential counts, Newton prepared to understanding the hypothesis of attractive energy. To the extent the possibility of all inclusive attractive energy is concerned, the basic work was done before Newton was twenty-four. In eighteen months, Newton composed what is viewed as the best logical work at any point composed. He called this book Philosophiae Principia Mathematica (Mathematical Principles of Natural Philosophy), which is typically known by the last two words. Ã¢â¬Å"In the book Newton classified GalileoÃ¢â¬â¢s discoveries into the three laws of motion.Ã¢â¬ (Wilson on the web) The main law of movement was called Ã¢â¬Å"the guideline of inertia.Ã¢â¬ Ã¢â¬Å"A body very still stays very still and a body moving stays moving at a consistent speed as long as outside powers are not involved.Ã¢â¬ (Wilson on the web) The second law of movement was named Ã¢â¬Å"motion characterized as far as mass and acceleration.Ã¢â¬ This was the principal away from between the mass of a body and its weight. He indicated that mass was only protection from speeding up; at the end of the day, mass is the measure of dormancy a body has. He likewise demonstrated that weight was the measure of gravitational power between a body and another body (the earth). The remainder of the popular laws was Ã¢â¬Å"action and reaction.Ã¢â¬ This law just expresses that for each activity, there is an equivalent and inverse response. That low administers the conduct of rockets. Utilizing these three laws, Newton had the option to make sense of the manner in which gravitational power between the earth and the moon could be determined. Since you could utilize that computatio n for any two bodies known to mankind, the condition turned into the law of all inclusive attractive energy. With this, he likewise determined the centripetal power expected to hold a stone in a sling, and the connection between the length of a pendulum and the hour of its swing. As you understand, Newton was a very balanced and insightful man. In addition to the fact that he did work with math and material science, yet he likewise found the fundamentals of optics. This is an image taken from ComptonÃ¢â¬â¢s Interactive Encyclopedia, 1997 Edition. AZTEC CIVILIZATION EssayPerhaps the most ideal approach to perceive what Sir Isaac Newton has given us is to take a gander at what we as a people rely upon most, the PC. Without the procedure of diagnostic geometry, otherwise called analytics, life wouldnÃ¢â¬â¢t be as simple as it is today. Implying that the time of PCs would have never come to fruition and without them, physical work would be utilized rather than robotized work, which would be much increasingly expensive, unfeasible, and wasteful. LetÃ¢â¬â¢s face it, it is only this straightforward, PCs run the world as we probably am aware it! We depend on PCs for everything, and without analytics, PCs may even now exist, yet the projects which run them would be nonexistent, just because of the way that the dominant part

Heres Everything You Need to Know About Et Al. Who speaks Latin anymore? Really, very few people do, however Latin phrases or abbreviations are abundant in English academic writing. Despite their initial confusion, they end up saving space and creating a more uniform format. So, if youve encountered one of these phrasesâ"et al. for exampleâ"youll eventually find it useful in your academic research.Think of it like riding a bike: Once you understand the concept, the rest is easy!Et al. means and othersEt al. has come to represent three different Latin phrases, particularly et alia (neuter plural), et alii (masculine plural), and et aliae (feminine plural). The definition from Merriam-Webster is and others.Photo by Jordan Donaldson | @jordi.d on UnsplashPhoto by Val Vesa on UnsplashWriting et al.Keep in mind that since the latter part of the expression et al. represents multiple Latin words, the correct way to punctuate it is to include a period at the end. Since et means and, there is no reason to put a period following it. Also , there is no reason to put et al. in italics, even though it is a Latin phrase (mainly because it has been used in the English language for hundreds of years).A look at an exampleTo see how et al. is used in an academic work, lets take a look at a sample paper pulled from the APA (American Psychological Association) website.Looking back at page two in the paper, The effects of age in the detection of emotion, youll see the following citation:(Carretie, Hinojosa, Marin-Loeches, Mecado Tapia, 2004).This is the first reference to this particular study, which according to APA rules, must include all authors names when initially mentioned.Now, moving to page four, at the top of the page, we see the following group of citations:(Calvo Lang, 2004; Carretie et al., 2004; Juth, Lundqvist, Karlsson, Ohman, 2005; Nummenmaa et al., 2006).The mention of Carretie et al., 2004 is referring to the same study we saw cited on page two. The only difference is the fact that it is no longer being me ntioned for the first time. Now, throughout the rest of the paper, the author can use et al. to refer to Carreties research writing partners without having to list all their names. The only exception is when listing it in the bibliography, works cited, or reference listâ"it must then include all authors names in the citation.More examplesAlthough et al. is mostly seen in academic writing contexts, it can also be used in less formal writing, while still maintaining the meaning and others. Here are some examples:Lets pack a picnic basket, with sandwiches, fruit, wine, cheese, et al.The loan officer wants paperwork turned in as soon as possible, including bank statements, tax documents, paycheck stubs, et al.Winter is finally hereâ"ice, sleet, et al.

Slavery and Religion in the English Colonies Many English immigrants came to America to seek religious freedom and some to improve their economic conditions. The concept of how slavery, thought by many colonists to be an economic necessity, was shaped and came to be rationalized and justified through Christian religious beliefs, is very interesting. The first English colonists settled in the Massachusetts colonies for religious reasons; to escape religious persecution in England as in the case of the Pilgrims or to start a new religious mission as with the Puritans. As the English crown sought to gain economically from the new world, their first successful settlements was in Jamestown, Virginia. JamestownÃ¢â¬â¢s economic success thrived through the Ã¢â¬Å"brown goldÃ¢â¬ or tobacco market. Growing tobacco, which takes approximately nine months, was very labor intensive and required a large number of manual workers. At first, they tried to use Native American Indians as their workforce. When this did not work, they used indentured servants, people who paid for passage to the New World by agreeing to work for an employer for a set number of years. Finally, after the indentured servant supply dried up and the number of new farms and large plantations grew in the English colonies, a new workforce was needed to take on this Ã¢â¬Å"back-breakingÃ¢â¬ work that no one else wanted to do and they turned to using African slaves.

Floyd Road, Richardson, TX 75083-0688, USA c School of Business and Management, Hong Kong University of Science and Technology, Clearwater Bay, Kowloon, Hong Kong, China Abstract We study the impact of activity-based costing (ABC) on adoption of world-class manufacturing (WCM) practices and plant performance. In contrast to earlier research that estimates the direct impact of ABC on plant performance, we develop an alternative research model to study the role of world-class manufacturing practices as a mediator of the impact of ABC. Analysis of data from a large cross-sectional sample of US manufacturing plants indicates that ABC has no signi? cant direct impact on plant performance, as measured by improvements in unit manufacturing costs, cycle time, and product quality. We ? nd, however, that WCM practices completely mediate the positive impact of ABC on plant performance, and thus advanced manufacturing capabilities represent a critical missing link in understanding the overall impact of ABC. Our results provide a di? rent conceptual lens to evaluate the relationship between ABC adoption and plant performance, and suggest that ABC adoption by itself does not improve plant performance.

Proponents of ABC argue that it provides accurate cost data needed to make appropriate strategic decisions in terms of product mix, sourcing, pricing, process improvement, and evaluation of business process performance (Cooper Kaplan, 1992; Swenson, 1995). These claims may have led many ? rms to adopt ABC systems. A survey of the 1000 largest ? rms in the United Kingdom showed that 19. 5% of these companies have adopted ABC (Innes Mitchell, 1995).

Prior research has typically focused on the direct impact of ABC while ignoring its indirect impact in supporting other organizational capabilities. While past studies have reported moderate levels of bene? s from ABC adoption (Foster Swenson, 1997; Ittner Larcker, 2001), few have extended this work to evaluate the linkages between Ã¢â¬ËÃ¢â¬ËbeliefsÃ¢â¬â¢Ã¢â¬â¢ that represent successful outcomes and the operational measures of plant performance. Furthermore, the de? nition of ABC success has often been vaguely de? ned in terms of subjective beliefs regarding Ã¢â¬ËÃ¢â¬Ë? nancial bene? tÃ¢â¬â¢Ã¢â¬â¢, Ã¢â¬ËÃ¢â¬Ësatisfaction with ABCÃ¢â¬â¢Ã¢â¬â¢, or Ã¢â¬ËÃ¢â¬Ëuse of ABC system for decision makingÃ¢â¬â¢Ã¢â¬â¢. In light of these methodological de? ciencies, we argue that a more rigorous approach is needed to measure the impact of ABC. It is also important to focus on process-level performance measures, instead of ? rm-level ? nancial metrics, since the potential impact of ABC implementation may be appropriated before they are re? ected in a ? rmÃ¢â¬â¢s aggregate performance. Evidence of past ABC implementation failures have led researchers to suggest that ABC success depends on other contextual and process factors, such as organizational structure, task characteristics, management support, information technology, and the external environment (Anderson, Hesford, Young, 2002). In this study, we focus on the mechanism through which ABC impacts plant performance, in terms of its role as an enabler of organizational capabilities rather than its direct impact. Speci? cally, we study the association between implementation of ABC and world-class manufacturing (WCM) capabilities, and their impact on plantlevel operational performance. Using a large cross-sectional sample of US manufacturing plants, we ? nd that ABC has a positive association with the development of process-centric capabiliImplementation of ABC has been observed not only in manufacturing ? rms but also in service sector ? rms (Cooper Kaplan, 1992). ties required to successfully implement WCM. We also ? nd that ABC does not have a signi? cant direct impact on plant performance measures. Instead, its impact on plant performance is mediated through the development of WCM capabilities, which allow plants to leverage the process capabilities o? ered by ABC into signi? cant improvements in plant perfor mance. Our study makes contributions in several areas. Our fundamental contribution involves the development of an empirically validated framework which indicates that the impact of ABC on plant performance is completely mediated through its enablement of WCM capabilities. Second, since ABC is implemented and used at the business process level, we focus our attention on operational process performance measures by treating the manufacturing plant as a unit of analysis. This allows us to avoid the drawbacks associated with prior studies which have mostly focused on aggregated, ? rm-level ? nancial measures. Third, our results suggest that the conceptual lens through which prior research has traditionally studied the impact of ABC needs to be revisited and validated using di? erent types of modeling and measurement approaches. Contrary to the ? dings of Ittner, Lanen, and Larcker (2002) we ? nd that, although the direct impact of ABC is not signi? cant, ABC has a statistically signi? cant indirect e? ect on plant performance that is mediated through its support for advanced manufacturing capabilities. The rest of our paper is organized as follows. In the next section, we review the related literature on ABC, advanced manufacturing practices, and plant per formance. We then present our conceptual research framework and research hypotheses, followed by a description of our research data and design. Next, we describe our statistical estimation results, followed by a discussion of our results, contributions, and limitations. We summarize our ? ndings and the implications of our study in the last section. Background The ABC literature de? nes an activity as a discrete task that a ? rm undertakes to make or deliver R. D. Banker et al. / Accounting, Organizations and Society 33 (2008) 1Ã¢â¬â19 3 a product/service, and uses cost drivers to assign activity costs to products, services or customers related to these activities (Cooper, 1988; Ittner et al. 2002). Traditional costing systems use bases like direct labor and machine hours to allocate expenses, associated with indirect and support activities, to products and services. On the other hand, ABC segregates the expenses of indirect and support resources by activities, and then assigns those expenses based on the drivers of these activities (Cooper Kaplan, 1991). Hence, ABC provides plant mangers with a more structured approach to evaluate the expenses associated with speci? c activities used to support a product. The body of prior research regarding the impact of ABC has produced mixed evidence. On one hand, proponents of ABC have argued that ABC helps to capture the economics of production processes more closely than traditional cost-based systems, and may provide more accurate costing data (Cooper Kaplan, 1991; Ittner, 1999). Prior research suggests that implementation of ABC should lead to operational and strategic bene? ts within organizations (Anderson Young, 1999; Cooper Kaplan, 1991). Researchers have argued that operational bene? s may emanate from improved visibility into the (a) economics of the production processes, and (b) causal cost drivers. Strategic bene? ts may arise from availability of better information for product development, sourcing, product mix and other strategic decisions (Anderson, 1995; Shields, 1995). Researchers have claimed that, since ABC may provide greater visibility into business processes and their cost drivers, it may allow managers to eliminate costs related to non-value added activities and improve the e? ciencies of existing processes (Carol? , 1996). Improved information visibility may also enable the deployment of quality-related initiatives by identifying activities that are associated with poor product quality, and their cost drivers (Ittner, 1999; Cooper, Kaplan, Maisel, Morrissey, Oehm, 1992). Hence, prior research suggests that ABC may be associated with adoption of process improvement activities, such as total quality management (TQM) programs (Ittner Larcker, 1997a, 1997b; Anderson et al. , 2002). On the other hand, Datar and Gupta (1994) claimed that increasing the number of cost pools and improving the speci? ation of cost bases may increase the frequency of errors in product cost measurement. Banker and Potter (1993) and Christensen and Demski (1997) suggest that the ability of ABC to produce accurate cost estimates depends on other factors, such as the competitiveness of markets and the quality of the organizationÃ¢â¬â¢s information technology infrastructure. Noreen (1991) suggests that ABC implementation may prov ide bene? cial results only under speci? c conditions. Similarly, empirical studies that have examined the impact of ABC on ? m performance have also produced mixed results (Ittner Larcker, 2001; Gordon Silvester, 1999). Many of these studies rely on managerÃ¢â¬â¢s beliefs regarding the success of ABC implementation, but they do not indicate whether ABC adopters achieved higher levels of operational or ? nancial performance compared to non-adopters (Shields, 1995; McGowan Klammer, 1997; Foster Swenson, 1997). Other studies have suggested that many ABC adopters have abandoned their implementations, raising concerns about the potential impact of ABC on performance (McGowan Klammer, 1997). In this study, e explore the relationships between ABC implementation and WCM practices, and their impact on plant performance. Unlike prior studies, which focus on measuring the direct impact of ABC on plant performance, our focus is directed at the role of ABC as an enabler of WCM practices which, in turn, have an impact on plant performance. In their study on relationships between incentive systems and JIT implementation, Fullerton and McWatters (2002, p. 711) note that the shift to world-class manufacturing strategies requires accompanying changes in ? rmsÃ¢â¬â¢ management accounting systems. They argue that by providing a better understanding of the inter-relationships between manufacturing processes, demand uncertainty and product complexity, ABC implementation allows plant managers to direct relevant process improvements which facilitate implementation of other WCM initiatives. Cooper and Kaplan (1991) also claim that ABC may help plant managers to develop a better 4 R. D. Banker et al. / Accounting, Organizations and Society 33 (2008) 1Ã¢â¬â19 understanding of the sources of cost variability, which allows them to manage resource demand and rationalize changes in product mix. The arguments in support of ABC are based on the presumed comparative advantage that ? rms may derive from greater transparency and accuracy of information obtained from ABC (Cagowin Bouwman, 2002). However, Kaplan (1993) and others have cautioned that not every ABC implementation will produce direct bene? ts. Indeed, the role of other facilitators and contextual factors, such as implementation of related organizational initiatives, has gained greater importance in this debate (Anderson et al. , 2002; Henri, 2006). A fundamental motivation of our research is to better understand the overall impact of ABC on plant performance by studying its indirect impact on plant WCM capabilities. We argue that ABC implementation should impact plant performance only by supporting the implementation of advanced manufacturing capabilities, which provide managers with the ? exibility to adapt to changing product and demand characteristics. Without such capabilities, ABC is unlikely to improve manufacturing performance by itself. Unlike previous studies that have studied the impact of ABC on ? rm-level performance, we bserve that isolating the impact of ABC at the plant-level allows us to trace ABCÃ¢â¬â¢s impact on speci? c plant performance measures, and overcomes the potential for confounding when multiple business processes are aggregated at the ? rm level. We discuss our conceptual framework and research hypotheses in the next section. Conceptual research model We posit that adoption of ABC by itself may no t provide much direct value, but may facilitate the implementation of advanced manufacturing practices and other organizational capabilities which, in turn, may be associated with sustainable improvements in plant performance. Unlike previous research that has in the large part explored the direct impact of ABC, our research model allows for the possibility of plant performance improvements due to implementation of WCM practices that may be enabled by capabilities associated with the adoption of ABC systems. WCM practices entail a broad range of manufacturing capabilities, which allow plant managers to adapt to the volatility and uncertainty associated with changes in customer demand and business cycles in agile manufacturing environments (Flynn, Schroeder, Flynn, 1999; Sakakibara, Flynn, Schroeder, Morris, 1997; Banker, Potter, Schroeder, 1995). These practices include just-in-time manufacturing (JIT), continuous process improvement, total quality management (TQM), competitive benchmarking, and worker autonomy through the use of self-directed work teams. Advanced manufacturing practices provide the capabilities necessary to react to rapid changes in lot sizes and setup times, as the manufacturing focus shifts to ? exible and agile processes that are characterized by quick changeover techniques to handle production of low volume orders with high product variety (Kaplan, 1983; Flynn et al. 1999). Traditional costing systems, which are based on assumptions of long production runs of a standard product with static speci? cations, are not relevant in such dynamically changing environments. However, proponents have argued that ABC may provide more accurate information on the activities and transactions that impact product costs in manufacturing environments characterized by production of smaller lot sizes, high broad mix, and freq uent changeovers (Krumwiede, 1998). By providing timely information about the costs of esources, especially when production runs are shorter or the production method changes, ABC implementation may provide the process infrastructure necessary to support managerial decision-making capabilities in fast-paced manufacturing processes (Kaplan, 1983). Hence, we study the impact of ABC on its ability to support implementation of WCM capabilities, and examine its indirect impact on plant performance through its enablement of such capabilities. Our conceptual research model describing the relationship between ABC, manufacturing capabilities and plant performance is shown in Fig. . The model comprises of two stages. The ? rst stage describes how ABC may facilitate implementation of world-class manufacturing practices. R. D.

Note: Plant performance is represented using three separate dependent variables that are grouped together in the gure for ease of representation. Our regression models are estimated using each performance variable as a dependent variable in a separate multivariate regression. The second stage describes the impact of advanced manufacturing capabilities, as embodied by WCM, on plant performance. The key di? erence between our research model and that of prior studies is our focus on the relationship between ABC and WCM, and the role of manufacturing capabilities as a mediator of the impact of ABC on plant performance, as represented by the dotted arrow in Fig. 1. Impact of activity-based costing on world-class manufacturing In his early work on the challenges of implementing new types of management accounting models to measure manufacturing performance, Kaplan (1983, p. 702) noted that Ã¢â¬ËÃ¢â¬Ë. . . accounting systems must be tightly integrated with plant production planning and scheduling systems so that production managers are rewarded for e? cient utilization of bottleneck resources and reduced inventory levels throughout the plant. . . Ã¢â¬â¢Ã¢â¬â¢. Prior research has suggested that ABC is more bene? cial when it supports the implementation of advanced manufacturing practices (Shields Young, 1989; Kaplan, 1992; Cooper, 1994). For example, Anderson and Young (1999) reviewed several ABC studies that reported positive relations between the success of ABC adoption and implementation of various advanced manufacturing practices. They argue that ABC facilitates more accurate identi? cation and measurement of the cost drivers associated with value added and non-value added manufacturing activities, which makes it easier to develop better cost control and resource allocation capabilities Ã¢â¬â necessary prerequisites for successful implementation of worldclass manufacturing. In world-class manufacturing environments, the accounting systems, compensation, incentive structure, and performance measurement practices are di? erent from those that are used in traditional manufacturing (Miltenburg, 1995; Milgrom Roberts, 1995). For example, traditional manufacturing processes entail the use of performance measures that track unit manufacturing costs related to (a) equipment utilization, (b) ratios of direct and indirect labor to volume, (c) number of set-ups, and (d) number of orders. On the other hand, erformance measures relevant to WCM implementation track (a) actual cost and quality, (b) cycle time reduction, (c) delivery time and ontime delivery rate, and (d) actual production as a percentage of planned production (Miltenburg, 1995, p. 336). By enabling the measurement of costs related to speci? c activities, products, and customers, ABC may provide more accurate identi? cation and measurement of new types of performance measures that are a critical compo nent of successful WCM implementations (Argyris Kaplan, 1994; Krumwiede, 1998). Proponents claim that ABC may support the implementation of WCM capabilities in several ways. First, by allowing plant managers to track costs accurately and enabling identi? cation of redundant resources, ABC may support implementation of TQM and other quality/process improvement programs. 2 Second, ABC may support process-related investments in cycle time See Ittner (1999) for an example of the bene? ts of activitybased costing for quality improvement at a telecommunications ? rm. 2 6 R. D. Banker et al. / Accounting, Organizations and Society 33 (2008) 1Ã¢â¬â19 reduction by facilitating the timely identi? ation of non-value-added activities (Kaplan, 1992). Third, ABC may allow plant managers to make better resource allocation decisions by focusing the product line and accurately anticipating the e? ect of changes in the product mix on the pro? tability of manufacturing operations. Hence, they argue that ABC implementation may provide the process discipline necessary to analyze activities, gather and trace costs to activities, and establish relevant output measuresÃ¢â¬âcapabilities that are useful in ? exible manufacturing environments (Cooper Kaplan, 1991, 1999). Implementation of ABC may be associated with greater use of self-directed teams and worker autonomy, which are also important capabilities of WCM (Anderson Young, 1999). Similarly, Ã¢â¬ËÃ¢â¬Ëbest practicesÃ¢â¬â¢Ã¢â¬â¢ data on cost pools, activity centers, and cost drivers can be incorporated into the design and use of ABC systems which may improve plant managersÃ¢â¬â¢ abilities to make better strategic product decisions, and thereby support implementation of WCM programs (Elnathan, Lin, Young, 1996; Atkinson, Banker, Kaplan, Young, 2001). Therefore, we posit that ABC facilitates successful implementation of WCM capabilities. In contrast to Ittner et al. (2002), who treat advanced manufacturing practices as causal variables in explaining adoption of ABC, we posit that ABC supports implementation of WCM practices, which in turn, may improve plant performance. Accordingly, Hypothesis H1: Plants which implement ABC are more likely to implement world-class manufacturing practices. Impact of world-class manufacturing on plant performance Implementation of WCM practices can enable plants to react quickly to changes in customer demand, and thereby carry lower levels of inventory, improve cost e? iencies, increase the ? exibility of production facilities through use of planning and scheduling software, and improve overall plant productivity (Banker, Bardhan, Chang, Lin, 2006). Investments in JIT and ? exible manufacturing practices help to reduce setup times that permit shorter production runs, thereby allowing for more e? cient inventory control, as well as lower product defect rates (Kaplan, 1983; Hendricks S inghal, 1997; Sakakibara et al. , 1997). Techniques that are commonly deployed, within the scope of JIT implementations, include pull/Kanban systems, lot-size reductions, cycletime reductions, quick changeover techniques, and bottleneck removal practices. Research on the performance impact of JIT has been extensively documented in the literature (Sakakibara et al. , 1997; Hendricks Singhal, 1997). Reported bene? ts range from reduced work in progress and ? nished goods, to better quality and higher ? rm productivity. Based on prior empirical evidence, researchers have found that ? ms which adopted JIT production are better aligned to customer needs, have shorter lead times, and faster time to market (Srinivasan, Kekre, Mukhopadhyay, 1994). Implementation of WCM practices also entails adoption of other process improvement practices, such as total quality management (TQM) and continuous process improvement programs (Fullerton McWatters, 2002). The fundamental elements of process improvement programs consist of competitive benchmarking, statistical process control, and employee empowerment (Schroeder Flynn, 2001). Such process improvement practices, stemming from greater attention to product quality and time to market issues may enable manufacturing plants to develop advanced manufacturing capabilities. Based on ? rm-level data, researchers have found that implementation of TQM and other advanced manufacturing practices have a positive impact on ? rm performance, through realization of lower product cost, higher quality, and better on-time delivery performance (Banker, Field, Sinha, 2001; Banker et al. , 1995; Hendricks Singhal, 1997; Ittner Larcker, 1995, 1997a). Hence, we posit that implementation of WCM practices in manufacturing plants may be positively related to improvements in plant-level performance as de? ned by plant cost, quality and time-to-market measures. Therefore, we hypothesize that R. D. Banker et al. / Accounting, Organizations and Society 33 (2008) 1Ã¢â¬â19 7 Hypothesis H2: Plants that have implemented WCM practices are more likely to be associated with signi? cant improvements in plant performance. H2a: Plants which implement WCM practices are more likely to realize improvements in plant manufacturing costs. H2b: Plants with WCM practices are more likely to realize improvements in plant quality. H2c: Plants with WCM practices are more likely to realize improvements in time to market. Impact of ABC on plant performance: a mediation mechanism Proponents have argued that, by enabling easier identi? cation of non-value added activities and simpli? cation of cost measurements, ABC enables implementation of advanced manufacturing practices, especially in processes that are characterized by quick changeovers and a range of support activities. Documenting and understanding activities is a necessary prerequisite to improving business processes, since activities are the building blocks of business processes. If ABC adoption results in more accurate costing then plant performance may improve because of greater ability to implement process improvement initiatives, facilitating the simpli? cation of business processes by removing non-value added activities. Successful implementation of WCM practices requires the development of business process models to identify and eliminate non-value added activities. In this respect, ABC implementation entails a priori development of such process models to identify and analyze activities, trace costs to activities, and analyze activity-based costs. Similarly, plant managers can use information gathered through ABC analyses to conduct a Pareto analyses of the major cost drivers, an important ingredient in most TQM and competitive bench3 marking initiatives. Scenario analysis related to pricing, product mix, and pro? tability is also possible, which are useful in the deployment of JIT capabilities. Hence, successful WCM implementations may leverage the streamlining of business processes due to ABC adoption. ABC analyses allow plants to develop activitybased management (ABM) business models which managers may adopt to improve their organizational e? ectiveness (Chenhall Lang? eld-Smith, 1998). In addition, ABC implementation may be correlated with and hence serve as a surrogate for unobservable factors, such as management leadership and worker training, that are important components of successful WCM implementation. Hence, implementation of WCM may allow plants to leverage the capabilities o? ered by ABC (i. . accurate cost allocations and management support) into improvements in plant performance. Our approach di? ers from the prior literature which has primarily studied the direct impact of ABC on plant performance (Ittner et al. , 2002). Instead, we argue that it is important to view the role of ABC as a potential enabler of manufacturing capabilities, and study its indirect impact on plant performance as completely mediated by WCM. This perspective argues that ABC may support improvements in manufacturing capabilities which are, in turn, associated with improvements in plant performance (Henri, 2006). Hypothesis H3: The positive association between ABC implementation and plant performance is mediated through implementation of worldclass manufacturing practices. An alternative perspective, with respect to the role of ABC, is that the interaction between WCM capabilities and ABC implementation may jointly determine plant performance. The interaction perspective argues that advanced manufacturing capabilities, when combined with deployment of ABC methods, create complementarities that explain variations in plant performance (Cagowin Bouwman, 2002). In other words, WCM and ABC may each have a direct e? ct on performance, but would add more value when used in combination (i. e. , the presence of WCM will increase the Low volume production creates more transactions per unit manufactured than high volume production (Cooper Kaplan, 1988). 8 R. D. Banker et al. / Accounting, Organizations and Society 33 (2008) 1Ã¢â¬â19 strength of the relationship between ABC and performance). In this framework, the interaction e? ects of ABC and WCM need to be estimated to study the overall impact of ABC on plant performance. We explore the interaction perspective further when we discuss our estimation results. Fig. represents the conceptual research model that describes our hypothesized relationship between ABC and implementation of WCM practices, and the role of WCM as a mediator of the impact of ABC on plant performance. Research design We now describe the characteristics of the data collected and approach for measuring the variables of interest in our study. Data collection Data for this research was drawn from a survey of manufacturing plants across the US, conducted in the year 1999 by IndustryWeek and PricewaterhouseCoopers Consulting. The survey consisted of a questionnaire which was mailed to plants with two-digit standard industrial classi? ation (SIC) codes from 20 to 39, and that employed a minimum of 100 people. Data were collected on a range of manufacturing, mana gement and accounting practices used within each plant. We have described the questions relevant to our research model in Appendix. The survey was mailed to approximately 27,000 plant managers and controllers from IndustryWeekÃ¢â¬â¢s database of manufacturing plants. Plant managers provided data on the extent of implementation of ABC and a broad range of advanced manufacturing practices and plant characteristics. Data on plant performance measures were based on assessments of plant records by plant controllers. A total of 1757 plants responded to the questionnaire for an overall response rate of 6. 5%. The usable sample contains 1250 plants that provided Since data on the independent and dependent variables was provided by di? erent sources, this mitigates the concerns associated with common methods bias. 4 complete responses to the variables of interest in our model. 5 We present the distribution of the manufacturing plants in our sample by industry in Table 1, and compare it to the distribution of manufacturers, reported in the Statistical Abstract of the United States and published by the US Census Bureau (2000). Since we obtained the data from a secondary data source, we did not have information with respect to the pro? les of non-respondent plants. To evaluate the generalizibility of our ? ndings, we compared the average plant productivity per employee of our sample plants to the average productivity of all US manufacturing plants, as reported by the US Census Bureau (2000). The average plant productivity per employee of our sample was $221,698, while the average productivity in the US Census data was reported to be $225,440. The di? erence in average plant productivity was not statistically signi? cant (t-statistic = 0. 37; p-value = 0. 35). Measurement of variables The ABC adoption variable was de? ned based on the response to the survey question asking whether ABC was implemented at the plant (0 = not implemented, 1 = plan to implement, 2 = extensively implemented). For the purpose of our study, we collapsed the ? rst two categories into one category, which represents plants that have not implemented ABC at the time of the survey. Hence, we measure ABC as a 0Ã¢â¬â1 dummy variable where zero represents Ã¢â¬ËÃ¢â¬Ëno implementationÃ¢â¬â¢Ã¢â¬â¢ and one represents Ã¢â¬ËÃ¢â¬Ëextensive implementationÃ¢â¬â¢Ã¢â¬â¢. The number of plants that have adopted ABC extensively in our sample is 248, an adoption rate of 19. 8%. We have three dependent variables in our research model. The variable DCOST denotes the change in unit manufacturing costs in the last ? ve years. DQUALITY denotes the change in plant ? rst-pass quality yield in the last ? ve years. DTIME 5 While the net usable response rate of 4. 6% is small, it is comparable to large plant operations surveys as reported in Stock, Greis, and Kasarda (2000) and Roth and van der Velde (1991). R.

The measurement scale of the plant performance variables was ordered in manner such that higher values represent improvements in performance over time. 6 WCM represents a composite factor that consists of six types of advanced manufacturing practices, as described in the survey questionnaire. The six indicators were measured using a 0Ã¢â¬â1 scale, where zero represents Ã¢â¬ËÃ¢â¬Ëno or some implementationÃ¢â¬â¢Ã¢â¬â¢, and one indicates Ã¢â¬ËÃ¢â¬Ëextensive implementationÃ¢â¬â¢Ã¢â¬â¢. Next, we constructed WCM as a six-item 6 A value of DQUALITY = 1 indicates that ? rst-pass quality yield Ã¢â¬ËÃ¢â¬Ëdeclined more than 20%Ã¢â¬â¢Ã¢â¬â¢, while DQUALITY = 5 indicates that quality yield Ã¢â¬ËÃ¢â¬Ëimproved more than 20%Ã¢â¬â¢Ã¢â¬â¢. On the other hand, DCOST = 1 indicates that unit manufacturing costs Ã¢â¬ËÃ¢â¬Ëincreased more than 20%Ã¢â¬â¢Ã¢â¬â¢, while DCOST = 7 suggests that costs Ã¢â¬ËÃ¢â¬Ëdecreased more than 20%Ã¢â¬â¢Ã¢â¬â¢. summative index that represents the degree of implementation of the six types of advanced manufacturing capabilities. This index measures both the range and depth of manufacturing capabilities in each plant. Hence, for each plant, WCM consists of seven levels and can take any value between zero and six (since the six indicators are measured as 0Ã¢â¬â1 variables). Our approach for constructing this summative measure of manufacturing capability is consistent with similar approaches in the literature (Krumwiede, 1998; Loh Venkatraman, 1995) that use a summative index when an increase in any of the indicators is associated with a corresponding increase in the construct of interest. We note that exploratory factor analyses (EFA) suggests that the six items load on a single factor (with Eigen value = 2. 13) which accounts for 36% of variance in the data. Furthermore, the EFA provides support for the validity and unidimensionality of the WCM factor. 7 10 R. D.

Our methodology is consistent with KrumwiedeÃ¢â¬â¢s (1998) approach to evaluate the antecedents of di? erent stages of ABC implementation in ABC WCM DISCRETE We include additional variables to control for the impact of plant characteristics on manufacturing capabilities and plant performance. There are six control variables in our model, which include plant size (SIZE) measured in terms of number of employees, plant age in years (PLANTAGE), nature of manufacturing operations (DISCRETE), degree of product mix (MIX), product volume (VOLUME), and the extent of downsizing in the last ? ve years (DOWNSIZE). Larger plants are more likely to have the scale and ? nancial resources required to justify adoption of advanced manufacturing practices and activity-based costing programs. SIZE is likely to impact plant performance since smaller plants are likely to be more agile in responding to customer needs compared to larger plants ceteris paribus (Hendricks Singhal, 1997). Plant AGE is also likely to play a signi? cant role since older plants are less likely to adopt advanced manufacturing practices and often fail to realize the impact of technology-enabled processes on plant performance. Product MIX is de? ed as the mix of products produced and is measured as a binary variable based on low or high product diversity. Plants with high product diversity are more likely to implement ABC (Cooper, 1989) as it may provide more accurate estimates of overhead usage. DISCRETE represents a binary variable with a value of one if the nature of manufacturing for primary products is discrete manufacturing , and zero for process or hybrid manufacturing. Descriptive statistics of our model variables are provided in Table 2. DOWNSIZE SIZE PLANTAGE VOLUME MIX DCOST DQUALITY DTIME R. D. Banker et al. / Accounting, Organizations and Society 33 (2008) 1Ã¢â¬â19 1 manufacturing ? rms. Tests for multicollinearity (Belsley, Kuh, Welsch, 1980) indicated no evidence of multicollinearity in our data (BKW index = 1. 06, variance in? ation factor = 1. 15). Our ordered logit regression results are presented in Table 3. The Ã¢â¬ËÃ¢â¬Ëlogit coe? cientÃ¢â¬â¢Ã¢â¬â¢ column reports the results of an ordered logit test for the seven states of WCM. The logit results indicate that our model has significant explanatory power (Chi-square = 82. 67; pseudo R2 = 0. 07). The ordered logit coe? cients indicate that adoption of ABC has a positive impact on WCM implementation (coe? ient value = 0. 499; v2 = 15. 15; p-value 0. 0001). Hence, our results support hypothesis H1, and suggest that plants that im plement ABC are more likely to implement WCM practices. The ordered logit results also indicate that plant SIZE and product VOLUME have a positive impact on the extent of WCM implementation. Larger plants may be more likely to implement WCM capabilities due to availability of greater plant resources, and plants with high VOLUME may be more likely to implement WCM to deal with the complexity involved in managing high volume production. The mediating role of WCM Next, we estimate the impact of ABC and WCM on the three measures of plant performance, DCOST, DQUALITY, and DTIME, using ordinary least squares (OLS) regressions. For each dependent variable, we estimate the relationships between ABC, WCM and plant performance as speci? ed by the following system of equations: DPERFORMANCE ? a0 ? a1 A ABC ? a2 A DOWNSIZE ? a3 A SIZE ? a4 A PLANTAGE ? a5 A DISCRETE ? a6 A VOLUME ? a7 A MIX ? e1 DPERFORMANCE ? b0 ? b1 A WCM ? b2 A DOWNSIZE ? b3 A SIZE ? b4 A PLANTAGE ? b5 A DISCRETE ? b6 A VOLUME ? b7 A MIX ? e2 ? 2? ?1? DPERFORMANCE ? d0 ? 1 A WCM ? d2 A ABC ? d3 A DOWNSIZE ? d4 A SIZE ? d5 A PLANTAGE ? d6 A DISCRETE ? d7 A VOLUME ? d8 A MIX ? e3 ?3? In order to test our proposed model, we follow the approach prescribed by Baron and Kenny (1986). Eq. (1) estimates the direct impact of ABC on plant performance. Eq. (2) estimates the marginal impact of the mediating variable, WCM, on plant performance. Eqs. (1) and (2) represe nt non-nested model speci? cations which estimate the independent impact of ABC and WCM, respectively, on plant performance. Finally, both predictor variables, ABC and WCM, are included in a single regression model speci? d in Eq. (3). We observe that Eq. (2) represents a complete mediation model, whereas Eq. (3) represents a partial mediation model where the impact of ABC is partially mediated through WCM. The dependent variable, DPERFORMANCE, represents the respective change (D) in the three performance measures: COST, QUALITY, and TIME. The system of equations estimated separately for each performance measure. We report OLS regression results in Table 4. 8 The estimated coe? cients in the three columns of each panel in Table 4 correspond to the regression models speci? ed in Eqs. (1)Ã¢â¬â(3). First, we estimate the direct impact of ABC on plant performance in the absence of the WCM variable. Estimated regression coe? cients for Eq. (1) are shown in columns (1), (4) and (7) of Table 4 (i. e. , ? rst column of each panel). The regression coe? cient of ABC is statistically signi? cant for DCOST and DTIME (p 0. 10), and it appears that ABC has a positive impact on improvements in plant costs and time to market. 9 ABC does not have signi? cant explanatory power in the DQUALITY regression model as indicated by low R2 values. 8 We also used ordered logit regressions to estimate the system of equations in (1). The ordered logit results are consistent with our OLS estimation results. 9 The adjusted R2 for these models was low (between 1. 38% and 2. 75%) and our analysis of the F-statistics indicates that only the DCOST regression model was signi? cant at p 0. 05. We have not included these results in our tables due to space limitations. 12 R. D.

PLANTAGE: Number of years since plant start-up. 1 = Less than 5 years; 2 = 5Ã¢â¬â10 years; 3 = 11Ã¢â¬â20 years; 4 = more than 20 years. VOLUME = 1 if plant exhibits high volume production, and zero otherwise. MIX = 1 if plant exhibits high product mix, and zero otherwise. Next, estimated regression coe? cients for Eq. (2) are shown in columns (2), (5) and (8) of Table 4. The regression results indicate that the impact of WCM on all plant performance measures is positive and signi? cant at p 0. 01. In other words, implementation of advanced manufacturing capabilities is associated with improvements in plant costs (b1 = 0. 20, p 0. 01), quality (b1 = 0. 14, p 0. 01), and time to market (b1 = 0. 16, p 0. 01). Hence, our results support hypothesis H2 with respect to the association between WCM implementation and performance. Finally, we estimate the full model in Eq. 3) that includes the direct impact of WCM on plant performance and an additional direct path from ABC to the dependent variable. The full model results, as reported in columns (3), (6), and (9) of Table 4, indicate that ABC does not have a direct, signi? cant impact on any of the three measures of plant performance.

In contrast, WCM continues to have a signi? cant positive impact on all plant performance measures, and the magnitude of the WCM coe? cient is very similar to its estimate in Eq. (2). The adjusted R2 values for the complete mediation models are not signi? cantly di? erent from the R2 values of their corresponding full (i. e. , partial mediation) models. For instance, adding the ABC variable in column (3) results in an increase of 0. 1% (=0. 001) in the DCOST modelÃ¢â¬â¢s explanatory power, compared to its corresponding R2 shown in column (2). Similarly, introducing ABC in the DQUALITY and DTIME models, results in statistically insigni? cant increases in model R2 of 0. 0% and 0. 1%, respectively. Hence, our results support hypothesis H3, indicating that WCM completely mediates the impact of ABC on plant performance. We also test an alternative speci? cation based on a perspective that the interaction between ABC and WCM implementation may have an impact on plant performance.

The results indicate that the interaction term (i. e. , ABC * WCM) is not statistically signi? cant for any of the plant performance measures.

These results indicate that the interaction model is not supported by empiri cal evidence based on analyses of the impact of ABC on operational measures of plant performance.

Comparison of two non-nested models We compared the R2 values associated with the ABC and WCM models in Table 4, and observe that WCM provides greater explanatory power of the variance in plant performance measures. In order to discriminate between these two competing speci? cations (i. e. , ABC ! Performance versus WCM ! Performance), we evaluate them as non-nested models using VuongÃ¢â¬â¢s (1989) likelihood ratio test for model selection that does not assume under the null that either model is true (Dechow, 1994). It allows us to determine which independent variable (ABC or WCM) has relatively more explanatory power, and represents a more powerful alternative since it can reject one hypothesis in favor of an alternative. We report the results of VuongÃ¢â¬â¢s test on nonnested models in Table 5. We conduct the VuongÃ¢â¬â¢s test for each pair of competing non-nested model speci? cations in Panels A, B, and C, of Table 4. Comparing the models in Eqs. (1) and (2) for the performance variable DCOST, we ? nd that VuongÃ¢â¬â¢s z-statistic of 4. 72 is signi? cant at p 0. 01, which indicates that the WCM model in Eq. (2) provides greater explanatory power of the variance in DCOST, compared to the ABC model in Eq. (1). Similarly, VuongÃ¢â¬â¢s z-statistic scores of 6. 91 and 7. 45 are statistically signi? cant (at p 0. 01) for the DQUALITY and DTIME models, respectively. Our results thus indicate that the direct role of ABC in explaining variations in plant performance is relatively small when compared to that of WCM. 10 Contrary to the ? dings reported A signi? cant z-statistic indicates that ABC is rejected in favor of WCM as a better predictor of variance in plant performance. *** Indicates signi? cance at the 1% level.

(2002), our ? ndings imply that the complete mediation model provides a superior speci? ation to study the impact of ABC on plant performance. Estimating the overall impact of ABC We next estimate the magnitude of the overall impact of ABC, based on the pathway that links ABC to DPERF through WCM, where DPERF represents the change (D) in COST, QUALITY, and TIME, respectively. We calculate the magnitude of the overall impact of ABC on DPERF as the cross-product of (a) the marginal impact of ABC on WCM, and (b) the marginal impact of WCM on DPERF. That is o? DPERF? o? DPERF? o? WCM? ? A o? ABC? o? WCM? o? ABC? ?5? 10 We also estimated the model, shown in Fig. 1, using structural equation model (SEM) analyses. We then estimated a reverse causal model (i. e. , WCM ! ABC ! Performance) to examine whether ABC is a better predictor of performance, compared to WCM. Our SEM ? t statistics for the reverse model fall outside the acceptable range for good model ? t. Consistent with the results reported above, and contrary to the ? ndings reported in Ittner et al. (2002), this suggests that WCM has greater explanatory power than ABC to explain variations in plant performance. The path estimates for the plant performance measures are shown in Table 6. Our results indicate that the overall impact of ABC on DCOST is equal to 0. 8 which is statistically signi? cant at p 0. 05. Similarly, the overall impact of ABC R. D. Banker et al. / Accounting, Organizations and Society 33 (2008) 1Ã¢â¬â19 15 on DQUALITY and DTIME are signi? cant, and equal to 0. 05 and 0. 06, respectively. Hence, our results support H3 and indicate that there exists an indirect relationship between ABC and plant performance, where WCM completely mediates the impact of ABC on performance. These results are consistent with our theoretical framework which suggests that, although ABC does not have a direct impact, it has a signi? cant overall impact on performance. 11 Discussion We highlight the role played by WCM as a mediator of the impact of ABC on plant performance. We ? nd that ABC has a signi? cant overall impact on reduction in product time to market and unit manufacturing costs, and on improvement in quality. Our results are consistent with prior research which suggests that successful implementation of advanced manufacturing initiatives requires prior adoption of compatible management accounting systems (Milgrom Roberts, 1995; Shields, 1995; Ittner Larcker, 1995; Sim Killough, 1998). Furthermore, our results indicate that WCM practices enable plants to leverage the capabilities o? red by ABC implementation and to signi? cantly improve plant performance. Our study has several limitations. First, the survey instrument measures beliefs about changes in plant performance over a ? ve-year period. These measures need to be validated through archival and ? eld data collection in future research. Second, it is possible that ABC may have been i n place beforehand or implemented sometime during the ? ve-year period. The secondary nature of the data did not allow us to separate the implications We also extended our research model to study the indirect impact of ABC on change in plant-level return on assets (ROA), a key ? ancial performance measure. We found that ABC has a signi? cant, positive impact on DROA which is mediated through its impact on WCM. Our ROA results are consistent with our results on the inter-relationships between ABC, WCM, and plant operational performance reported here. 11 of these possibilities. Future studies must be designed to gather more detailed data, about the timeline of ABC implementation to better understand its impact on plant performance especially since users may need training to adapt to new types of costing procedures. ABC implementation was measured as a 0Ã¢â¬â1 variable in our study. It is possible that using a more granular scale to measure the extent of ABC implementation, including the level of ABC integration and the time lag since ABC implementation, may provide greater insights on the relationship between ABC and plant performance. Our focus on plants that employ a minimum of 100 employees limits the generalizability of our results to industries with relatively large or very small manufacturing plants. We also did not account for country or cultural di? rences in manufacturing characteristics since the scope of the survey was limited to US plants. Our ? ndings must also be validated with additional data collected in industry-speci? c settings to examine the impact of industry characteristics and di? erences in manufacturing strategies. Future research may also include evaluation of other contextual factors that are associated with the success of ABC implementation, such as process infras tructure, and the extent of human resource support and outsourcing. Our study enhances the quality of the extant body of knowledge on ABC e? ectiveness in several ways. First, our survey responses were data provided by plant managers who may represent a more objective and knowledgeable source of plant-wide operations compared to many previous studies, that relied on respondents (such as ABC project managers) with a personal stake in ABC success (Shields, 1995; Swenson, 1995). Second, ABC non-adopters were identi? ed based on the responses provided by plant managers, unlike prior studies where non-adopters were identi? ed based on the lack of public information on ABC implementation (Balakrishnan, Linsmeier, Venkatachalam, 1996; Gordon Silvester, 1999). Third, we treated the manufacturing plant (instead of the ? rm) as the unit of analysis, which allowed us to observe the impact of ABC implementation on changes in process-level performance metrics 16 R.

Conclusion In contrast to prior studies (Ittner et al. 2002) that have typically focused on the direct impact of ABC on plant performance, we study the role of world-class manufacturing practices in mediating the impact of ABC on plant performance. We draw on prior research on the relationship between management accounting systems and business processes to better understand how ABC may support implementation of WCM practices. Analyzing data from a large cross-sectional sample of US manufacturing plants, we ? nd eviden ce supporting our model emphasizing the role of advanced manufacturing practices in improving plant performance. Our ? ndings emphasize the need for ? ms to strengthen their manufacturing capabilities when making an investment to implement ABC systems, as ABC is unlikely to result in improved manufacturing performance by itself. Our evidence also suggests that plants can reap signi? cant bene? ts by combining ABC implementation with the deployment of advanced manufacturing practices. Using a conceptual lens that focuses on the indirect impact of ABC, the evidence supports our alternative theoretical perspective to prior research. We conceptualize ABC as only an enabler of world-class manufacturing practices, which in turn is associated with improvements in plant performance. Our Ã¢â¬ËÃ¢â¬Ëcomplete mediationÃ¢â¬â¢Ã¢â¬â¢ model stands in contrast with earlier models proposed by Ittner et al. (2002) who focus primarily on the direct impact of ABC on plant performance. The results indicate that our alternative conceptualization is superior in terms of its ability to explain variations in plant performance based on cross-sectional data of a large sample of plants that have implemented ABC. Furthermore, our proposed model may provide an avenue for future researchers using di? erent methodologies to explain di? erences in performance improvements following ABC implementations. It may also explain the weak or ambiguous results in prior research on ABC impact because ABC adoption may not be a su? cient statistic for WCM. Appendix: Survey questions I.

The leaderÃ¢â¬â¢s leadership styles play a very important role in achieving goals of the organization. The leaderÃ¢â¬â¢s ability to adapt to internal and external environment changes and working with followers together is the key to success. Moreover, I should mention that many causal modeling revealed that leadership style has a direct, rather than indirect, effect on task performance. Highly complex and stress-laden workplaces present challenges to organizational leaders as they are faced with the task of managing the workforce while concurrently maintaining commitment and morale. Leaders can often be in the middle source of stress among employees in the workplace (Basch Fisher, 2000; Sosik Godshalk, 2000). As the distinctiveness of work changes, so must change the roles and tactics of all leaders. The Leader promote supportive relationships, elicit motivation along with assistants/followers, make possible more positive and less negative emotions along with assistants, and stimulate more kind evaluations of stressful tasks among assistants may be more effective than the more conventional leaders who usually tend toward task-directive methods.

Despite a considerable body of literature suggests that leaders based on transformational are effective, there is a small number of experimental research that has discovered how transformational leaders may impact subordinates/followers during stressful business deals. Taking into above mentioned I am to deal with transformational and transactional leadership styles their influence on different subordinate including emotional and motivational experiences. The effects of leadership style based on stressful task performance were examined (by Joseph B. Lyons, Tamara R. Schneider 2009) as potential mediators, further. 2. 0 The Nature of Leadership and Job Stress 2. 1 Leadership Style In the field of organizational behavior the leadership is really an important subject. Leadership is one with the most dynamic effects during individual and organizational interaction. In other words, whether a management is able to execute Ã¢â¬Å"collaborated effortÃ¢â¬ depends on leadership capability.
