Sarbanes-Oxley (SOX)section 404reporting requirements.Design/methodology/approach –Data on firms that reported internal control weaknesses for fiscal year 2004are collected,and determined whether these weaknesses still existed in their 2005filings.Logistic regression is used to examine the impact of corporate governance,resource,impediments (e.g.severity of weakness),and Big 4auditor status on remediation completion.Findings –Resources (e.g.size,ROA)were positively associated with e of Big 4auditor,more audit committee meetings,more business segments,and filing lag were negatively associated with remediation,as were number and type of internal control weaknesses.Research limitations/implications –First,the paper sheds light on the individual firm factors that influence corporate response to the legal and social (e.g.public pressure)environment facing firms.Understanding this should better enable policy makers and regulators to foresee where potential lags in firm implementation of regulations may occur,and why.Second,it believes that the paper also sheds light on the relative value of different corporate governance structures in meeting investor concerns for proper stewardship of their investments.Finally,this paper provides information of use to other corporate governance researchers in that the results suggest the overwhelming importance of the legal and social environment in influencing corporate behavior.However,this paper does not address the contribution of national culture,financial and audit-related reporting requirements,and differences in firm resources,to corporate behavior.Originality/value –The paper deepens the field’s understanding of the determinants of internal control weakness remediation,furthering regulators’understanding of SOX’s impact.Keywords Corporate governance,Internal control,Financial reporting Paper type Research paper1.IntroductionIn reaction to the many flaws that the Enron/Anderson scandal revealed in the workings of corporate governance and auditing in the USA,the US government passed the Sarbanes-Oxley (SOX)Act of 2002.The then head of PricewaterhouseCoopers,Dennis Nally,called SOX “the most significant change to the securities laws since they were put into effect in the mid-1930’s”(Nocera,2005).As Nocera notes,SOX has had many critics,including those who state that it would not have prevented the very frauds that largely gave it life,i.e.those of Enron and Worldcom.Further,the change came at very high cost.It has been claimed that the change raised the cost of being aThe current

ManagementVol.17No.1,2009pp.53-65q Emerald Group Publishing Limited1834-7649DOI 10.1108/18347640910967735public company by 233percent (Nocera,2005;Gupta and Nayar,2007).Of the many sections of SOX,section 404came under the most criticism because it mandates that firms assess their internal control systems,and that the auditors also now provide an opinion on those systems,annually.Given the importance of SOX in the post-Enron/Worldcomm corporate legal landscape,and given SOX’s requirements for improved corporate governance,the impact of SOX’s provisions for internal control review and remediation on the actual practice of corporations is an important research question.This study explores the impact of the changed regulatory environment and firm characteristics on remediation of internal control weaknesses.Specifically,we examine whether or not:.the mere passage of the SOX itself leads corporations to remediate their internal control weaknesses;or .there are firm characteristics that affect the successful remediation of the internal control weaknesses.Changes in corporate legal environments would impact corporate behavior.As Venard and Hanafi(2008,p.482)note:“Various institutions shape organizations including social,cultural,economic,and political institutions (Scott,1995).”Venard and Hanafialso note that legal structures and law enforcement are important parts of the environment,helping to determine the level of pressure that firms feel and react to in making a decision to comply with legal environmental pressures.Given that SOX has passed,it implies that all internal control issues would have been resolved upon the firms’realizations that they existed.Certainly the mandate for change is there.To the extent that firms realize that their behavior is observable,certainly true after the implementation of SOX,they have strong incentives to repair perceived defects in their internal control systems,irrespective of the level of financial expertise on their audit committees,etc.[1].To achieve our objective,we examine a sample of accelerated filers subject to the internal control reporting provisions of section 404[2].Thus,all firms that meet the definition of an accelerated filer face the same legal environment.The impact of the legal environment may differ among different firms in the sample if the organs through which the firms understand that environment differ.These differences may include the quality of their audit committees or the sophistication of their auditing firms.Even if the legal environment is understood correctly,the behavioral implications of that understanding may differ given different resources of the firms facing the problems of implementing the SOX mandated reforms.For example,larger and more profitable firms with more resources are more likely to fix their internal control problems.Accordingly,our study examines the contribution that corporate governance structures and firm characteristics make to the decision to remediate previously disclosed internal control weaknesses.Specifically,we examine factors that are associated with whether firms reporting material internal control weaknesses in 2004under section 404have successfully fixed the internal control weaknesses by the time the auditor opinions on internal controls were issued in 2005.We believe that this study makes several contributions to the literature.First,it sheds light on the individual firm factors that influence corporate response to the legal and social (e.g.public pressure)environment facing firms.Understanding this shouldIJAIM 17,154better enable policy makers and regulators to foresee where potential lags infirm implementation of regulations may occur,and why.Second,we believe that our study also sheds light on the relative value of different corporate governance structures in meeting investor concerns for proper stewardship of their investments.Finally,our study provides information of use to other corporate governance researchers in that our results suggest the importance of the legal and social environment in influencing corporate behavior.The fact that not allfirms have remediated their2004internal control weaknesses by the time these systems were examined in2005,suggests additional research is needed as to the reason for that remediation failure.Ourfindings show that out of243firms reported material internal control weaknesses under section404of SOX in2004,only72percent of thefirms have successfully remediated their internal control weaknesses by2005.The other 28percent of thefirms continued to report material weaknesses in their2005section 404reports.Thus,the passage of SOX by itself does not necessary ensure that internal control problems arefixed byfirms.Liou and Yang(2008)show that the ability to detect fraudulent reporting in advance can improve the accuracy of business failure prediction models.Since Chan et al.(2008a)find thatfirms reporting ineffective internal controls under section404engage in earnings management,other researchers can incorporate that information in developing such models.We alsofind thatfirm characteristics such asfirm size,return on assets,number of operating segments,filing lag in2004,use of Big4auditors,number of audit committee meetings,and the number and type of internal control weaknesses are associated with the probability that the material weaknesses reported in2004werefixed in2005.The rest of this study is organized as follows.Section2provides a summary of the related studies and the research hypotheses.Section3presents the research design and Section4summarizes the researchfindings.Concluding remarks are provided in Section5.2.Related studies and research hypothesesIn conducting this study,we use many variables previously indicated as important in understanding corporate behavior with regard to internal control weaknesses revealed under section302and section404of SOX.Ashbaugh-Skaife et al.(2007)and Doyle et al. (2007)document thatfirms disclosing internal control deficiency under section302and section404of SOX tend to be smaller and less profitable since thesefirms would have less resources to be invested on their internal controls.In addition,firms reporting material weaknesses have more business segments compared to otherfirms.Given the additional audit work for section404review,Ettredge et al.(2006)report significant delay infirms’SECfilings forfiscal year2004.Since company general internal control weaknesses are considered to be more serious problems than account specific weaknesses,the authors alsofind that thefiling delay is longer forfirms with company general internal control weaknesses.Li et al.(2008)alsofind thatfirms reported ineffective internal control under section404often have significant subsequent turnover in their chieffinancial officers.Chan et al.(2008b)argued,based on their summary of the literature that the following variables may be important in understanding why management and auditors fail to identify ineffective internal controls in their initial internal control review.These variables include the extent of theThe impact of Sarbanes-Oxley55control weaknesses,the size of the firm,the nature of the auditor (Big 4or not),and the number of audit committee meetings.We expect that the above firm characteristics are associated with the probability that firms would successfully fix their material internal control rger and more profitable firms should be more likely to fix their internal control problems since these firms would have more financial resources.We sought also to understand the impact of the use of a Big 4auditor on remediation.The literature has often regarded the use of a Big 4auditor as a marker of the quality of the audit (Becker et al.,1998).On one hand,firms with Big 4auditors could be more likely to fix the internal control problems,given the possibility of receiving better advice from the auditors.On the other hand,Big 4auditors could have higher thresholds before concluding that the internal control weaknesses have been remediated.We also expect firms with fewer internal control weaknesses or account specific weaknesses are more likely to have successful remediation since these firms have fewer,or less serious,internal control problems.Further,we examine the impact of corporate governance on the probability that internal control weaknesses were fixed.Krishnan (2005)shows that audit committee independence and financial expertise are highly associated with the absence of internal control problems for sample firms that changed auditors.Anderson et al.(2004)document that audit committee size and meeting frequency are negatively related to firm’s cost of debt.Since one of the primary duties of an audit committee is to monitor the firm’s internal controls,a higher quality and more active audit committee is more likely to contribute to the remediation of internal control problems.However,it is also possible that the number of audit committee meetings could be negatively related to the remediation of internal control weaknesses since the number of audit committee meetings could be related to the severity of the internal control problems.Finally,the amount of time available to fix the ineffective internal controls in 2005would also impact the likelihood that the internal control problems are fixed in 2005.A delay in the issuance of an audit report for 2004would indicate less time to remediate internal control weaknesses by the time of issuance of the 2005audit report.The following section describes our sample and the empirical models used in investigating the impact of these factors on the probability that firms would successfully remediate their ineffective internal controls.3.Sample selection and empirical modelsInitial sample firms with material internal control weaknesses (i.e.ICW firms)in 2004and 2005are identified by searching the Audit Analytics database.Duplicate firms were excluded.Firms that are subsidiaries of other parent corporations are eliminated,as are Canadian and other foreign firms.This provides a subtotal of 362and 393ICW firms in 2004and 2005,respectively.We also identified and collected 3,276firms without material internal control weaknesses (i.e.non-ICW firms)in 2005from Audit Analytics by following the same sample attrition procedure.The 214remediated firms are further identified by comparing the above 362ICW firms in 2004and 3,276non-ICW firms in 2005.After deleting firms with missing audit committee data and financial data,the number of remediated firms is 174.Among the 174remedied firms,32firms have missing business segment data from Compustat.Moreover,the 93non-remedied firms are further identified by comparing the above 362ICW firms inIJAIM 17,1562004and393ICWfirms in2005.After excludingfirms without sufficient audit committee data andfinancial data,the number of non-remediedfirms is69.Among69 remediedfirms,17firms have missing business segment data from Compustat.Table I summarizes our sampling procedures.Further,the number of internal control weaknesses is collected from Audit Analytics.We also read the auditor’s section404report in order to classify afirm as having general or account specific weaknesses.Ettredge et al.(2006)state that general weaknesses include problems such as personnel training and the general control environment.Ettredge et al.(2006)cite revenue recognition and accruals as examples of account specific weaknesses.If afirm has both types of internal control weaknesses, afirm is considered as having a general weakness.Table II shows the industry distribution of thefinal sample,while Table III provides descriptive statistics on the overall sample as well as the sub-samples offirms that have or have not remediated their internal control weaknesses.Our main objective is to examine the factors associated with the probability offirms remedying material internal control weaknesses in their2004SOX404reports.Either all the internal control weaknesses reported in2004were remediated or they were not.

internal control weaknesses by the end of their 2005fiscal year.We follow Audit Analytic’s practice for defining the end of a fiscal year.It considers fiscal years that end up through 15days into the new calendar year to have ended with December 31of the immediately preceding calendar year.Under this definition,if a firm’s fiscal year ended on January 15,2006;the firm’s fiscal year would be considered to have ended in 2005.We chose firms whose fiscal years fell into the time frame of November 15,2005through January 15,2006;for our 2005fiscal year sample.We used a similar procedure for choosing firms with a 2004fiscal year end.Sixty-nine firms that had reportable internal control weaknesses in 2004did not completely remedy these weaknesses by the end of their 2005fiscal year.We used logistic regression analysis to examine those factors.All variables were winsorized with the cutoffs set at the 1and 99percent levels.We next present the variables that are to be examined.The main

our study.REM serves as the marker of that remediation.It equals 0if there has been no remediation,and 1otherwise.We examine the impact of personnel change on the remediation effort.Accordingly,we created variables to determine the impact of a change in the firm’s CEO (CEOCHG)and a change in the firm’s CFO (CFOCHG)on remediation.If there was a change in CEO from 2004to 2005,then CEOCHG equals 1,else it equals zero.The same held true for CFOCHG.SIZE is defined as the natural log of total assets at the end of fiscal year 2005and ROA is defined as 2005earnings divided by total assets at the end of the 2004fiscal year.SIZE and ROA represent the availability of resources for the remediation effort.We sought also to understand the impact of the use of a Big 4auditor on remediation.The literature has often regarded the use of a Big 4auditor as a marker of the quality of the audit (Becker et al.,1998).If firms used a Big 4auditor in 2005,the BIG 4auditor was coded as 1.Otherwise,it has the value of zero.If SIZE or ROA could be considered illustrative of resources available to perform remediation,we felt it was also important to consider the challenge of remediation.To that end,we created a variable denoted as ICW_NUM.This captured the number of material internal control weaknesses that the firm had in 2004.Both utilities and financial institutions are regulated industries.Given that these firms are subject to regulation beyond that typically experienced by firms in the United States,we created an indicator variable for each.If a firm in our sample had an SIC code of 49for utilities,we assigned a value of 1to the UTILITIES variable.Otherwise,UTILITIES was assigned a value of zero.We similarly constructed the FINANCIALS variable.Our ROA and SIZE variables were constructed to capture the effect of two financial resource variables.Other resources are available to the firms.To measure these,we constructed a variable to capture the impact of audit committee size on the firms (AC_SIZE).This was calculated as the number of members of the audit committee in 2005.Similarly,we sought to determine the impact on remediation of having a financial expert on the audit committee.The FINEXPERT variable is a simple count of the number of financial experts on the audit committee during 2005.In this regard,we also decided to investigate the impact of the number of audit committee meetings held in 2005,as reported in the proxy statement filed in 2006.To this end,we constructed a variable denoted as MEETING.Audit committee meeting frequency and audit committee size have been found to contribute to a lower cost of debt (Anderson et al.,2004)and thus may be considered perceivable indicators of audit committee quality.Time to remediate from the audit opinion for 2004to the audit opinion to 2005is another resource.Since a delay in the issuance of an audit report for 2004would indicate less time to remediate internal control weaknesses by the time of the 2005audit report issuance,we included a FILING_LAG variable.This was measured as the length of time between the filing of the 2004report to the filing of the 2005report.4.Empirical findingsThe results of the logistic analysis for model (1)are shown in the column (1)of Table IV.It seems that use of a Big 4auditor leaves the client firm less likely to remediate its internal control weaknesses.Greater numbers of internal control weaknesses also led to a lower probability of 2004internal control weaknesses being remediated by 2005.The positive coefficient on ROA indicates that greater returns on assets led to a higherIJAIM 17,160likelihood of internal control weakness remediation.The number of audit committee meetings (MEETING)was negatively associated with remediation.Finally,remediation of 2004internal control weaknesses was associated with a shorter filing lag.The other variables (CEOCHG,CFOCHG,SIZE,ICW_NUM,UTILITIES,AC_SIZE,and FINEXPERT)were not significant.We also perform several sensitivity analyses.In model (2)of Table IV,we asked whether the type of internal control weakness impacted the sample firms’remediation of 2004internal control weaknesses by the end of the 2005fiscal year.All the other variables are the same as in model (1),except that ICW_TYPE instead of ICW_NUM is used here.ICW_TYPE was set to 1if the material weaknesses were account specific weaknesses and was set to 0otherwise.If the firm had both general control weaknesses and account specific weaknesses,the variable was coded as 0.We expected the coefficient to be positive,that is account specific weaknesses were more likely to be remediated by the end of fiscal year 2005than were general control weaknesses (Ettredge et al.,2006;Doyle et al.,2007).The results for model (2)are shown in the column (2)of Table IV.Consistent with our expectations,ICW_TYPE was positive,indicating that account specific weaknesses in 2004were more likely to be remediated by fiscal year end 2005,than were general control weaknesses.Given that internal control systems may vary in complexity with the complexity of the business entity,we examine whether greater business segmentation would be indicative of greater control system complexity.The latter should make it more difficult to repair internal control weaknesses.Accordingly,we added a business segmentation variable to model (1)and denoted it as model (3)in Table IV.All variables in model (3)are same as those of the previous models,except a new variable BUS_SEG is added.The new variable,denoted BUS_SEG,is the number of businessModels(1)(2)(3)(4)Variables Expected signs Coefficient estimates Coefficient estimates Coefficient estimates Coefficient estimates Intercept 3.2632

关于现代科技对传统教育的影响英语作文全文共3篇示例，供读者参考篇1The Impact of Modern Technology on Traditional EducationIntroductionIn recent years, modern technology has revolutionized the way we live, work, and learn. In the field of education, traditional teaching methods are being challenged by the integration of technology into the classroom. This has led to a significant shift in how students are taught and how they learn. In this essay, we will explore the impact of modern technology on traditional education.Impact of Technology on Teaching MethodsOne of the most significant impacts of modern technology on traditional education is in the way teachers deliver their lessons. With the availability of digital tools such as interactive whiteboards, laptops, and tablets, teachers can now create engaging and interactive lessons that cater to the diverse learning styles of students. This has made teaching moreeffective and has helped students to better understand and retain information.In addition, technology has also made it easier for teachers to track student progress and provide personalized feedback. Online learning platforms and educational apps allow teachers to monitor student performance in real-time and tailor their lessons to address the individual needs of each student. This has helped to improve student outcomes and has made the learning process more efficient.Impact of Technology on LearningModern technology has also had a profound impact on how students learn. With access to a wealth of information online, students no longer have to rely solely on textbooks and classroom lectures to gain knowledge. They can now conduct research, watch educational videos, and participate in interactive learning activities that make learning more engaging and enjoyable.Furthermore, technology has also made learning more accessible to students with diverse learning needs. For example, students with disabilities can use assistive technology such as screen readers and speech recognition software to access educational materials and participate in classroom activities.

This leads to the decline of freshwater species, affecting both the ecosystem and the communities that depend on these resources for survival.In conclusion, climate change poses significant threats to the environment. The degradation of coral reefs, deforestation, and disruptions in freshwater ecosystems are just a few of the consequences. It is crucial for governments, industries, and individuals to take immediate action to reduce greenhouse gas emissions and protect the Earth’s ecosystems.文章三：The Ripple Effect: Climate Change’s Impact on theEnvironmentClimate change, an issue predominantly caused by human activities, creates a ripple effect that profoundly affects the environment. From the melting of polar ice caps to the shifting weather patterns, these changes are increasingly disrupting ecosystems and threatening the interconnected web of life on Earth.One striking consequence of climate change is the loss of habitat for many species. As temperatures rise, certain habitats become unsuitable for the plants and animals that depend on specific conditions for survival. This leads to range shifts and, in some cases, the extinction of plant and animal species. The disruption of these habitats creates a domino effect, impacting the entire food chain and altering the dynamics of ecosystems.Furthermore, climate change has a direct impact on the world’s oceans. The rise in sea levels, primarily caused by the melting of glaciers and ice sheets, puts coastal areas at risk of flooding and erosion. This endangers not only human populations but also critical coastal habitats such as mangroves and salt marshes. Additionally, ocean acidification resulting from increased carbon dioxideabsorption compromises the survival of many marine species, particularly those with calcified shells or skeletons.Moreover, climate change intensifies extreme weather events, including hurricanes, droughts, and wildfires. These disasters have devastating effects on both natural and human systems. They cause the destruction of forests, loss of biodiversity, displacement of communities, and economic hardships. The recovery and restoration of these affected areas can take significant time and resources.In conclusion, the impact of climate change on the environment is far-reaching and varied. Loss of habitat, rising sea levels, and more frequent extreme weather events are only a few examples of the consequences. To mitigate these effects and protect our planet, concerted efforts are needed to reduce greenhouse gas emissions and promote sustainable practices. The world must work together to safeguard the environment for future generations.。
