This study aims to investigate the impact of job rotation on employee performance and explores the mediating role of human resources (HR) strategy and training effectiveness on this relationship, within the petrochemical industry, which represents a highly specialist and hazardous industrial context.

Data was collected through a questionnaire which was distributed among the experts working in an Iranian petrochemical organization. Previously validated scales were used to measure job rotation, employee performance, HR strategy and training effectiveness, and partial least squares structural equation modeling was used for hypothesis testing.

The research findings indicated that job rotation had a negative effect on employee performance, while training effectiveness and HR strategy positively mediated the relationship between job rotation and employee performance. This highlights the importance of ensuring effective training and a HR strategy to support job rotation of skilled and specialist employees.

Managers of employees in specialist and hazardous industries, such as petrochemical workers, interested in job rotation to support employee career development, should be mindful of potential negative implications on employee performance. To support and improve employee performance, job rotation should be considered alongside HR strategy and training.

Previous research has largely focused on the value of job rotation to develop managers’ organizational understanding and to reduce injury within blue-collar work, which has led to a paucity of research into job rotation within highly skilled and specialist industrial roles. It is highlighted within the literature that it remains unclear what supports effective job rotation. This study addresses this lacuna by investigating how job rotation affects employee performance in a highly skilled and specialized industry and how strategy and training effectiveness mediate this effect.

To explore the effects of mandatory auditor rotation and retention on the long‐term market shares of the accounting firms that audit the members of the Standard and Poor's (S&P) 500.

A Markov model is constructed that depicts the movements of S&P 500 firms in the period 1995 to 1999 among Big 5 accounting firms. Auditor rotation and retention are reflected in the transition probabilities. The impacts of mandatory auditor rotation and retention policies are evaluated by examining the state probabilities after two, five, and nine years.

The paper finds that mandatory auditor rotation will have substantial effects on long‐term market shares, whereas mandatory auditor retention will have very small effects. It shows that a firm's ability to attract new clients, as opposed to retaining current clients, will be the primary factor in determining the firm's long‐term market share under mandatory auditor rotation.

The paper assumes that S&P 500 firms will continue their reliance on Big 5 firms and that the estimated transition probabilities will remain stable over time.

Excessive market share concentration resulting from such policies should not be a concern of regulators. The paper conjectures that, under mandatory rotation, accounting firms will reallocate resources to attract new clients rather than retain existing clients. This may result in lower audit quality.

Interestingly, over the past 25 years, several bodies have considered mandatory auditor rotation and retention. Surprisingly, the authors have found no studies of the effects of mandatory auditor rotation and retention on audit market share.

The form error of shaft and hole parts is inevitable because of the machining error caused by rotation error of tool axis in machine tools where the elliptical form error is the most common in shaft and bearing bush. The purpose of this paper is to present the relationship between the elliptical form error and rotation accuracy for hydrostatic journal bearing in precision spindle and rotation table.

An error averaging effect model of hydrostatic journal bearing is established by using Reynolds equation, pressure boundary conditions, flux continuity equation of the land and kinetic equation of shaft in hydrostatic journal bearing. The effects of shaft and bearing bush on rotation accuracy were analyzed quantitatively.

The results reveal that the effect of shaft elliptical form error on rotation accuracy was six times larger than bearing bush. Therefore, to improve the rotation accuracy of hydrostatic journal bearing in spindle or rotation table, the machining error of shaft should be controlled carefully.

An error averaging model is proposed to evaluate the effect of an elliptical form error on rotation accuracy of hydrostatic journal bearings, which solves the Reynolds equation, the flux continuity equation and the kinetic equation. The determination of form error parameters of shaft and bearing bush can be yielded from finding results of this study for precision design of hydrostatic journal bearings.

The purpose of this paper is to review the impact of a new, brief forensic rotation for general psychiatry residents on the variety of residents’ forensic exposures.

The authors surveyed residents who trained before and after the implementation of the new rotation to assess the impact of the rotation on the residents’ forensic experiences during training across a variety of domains.

Even in a highly clinical forensic setting, residents participating in the required rotation reported significantly greater variety of forensic experiences than those who had not completed the required rotation, including types of settings and assessments, Rotation completers reported greater exposure to various types of settings and assessments, and courtroom-related experiences, as well as the overall number of forensic exposures. The two groups did not differ in their forensic exposures in general psychiatry settings, civil-forensic evaluations or diverse forensic populations. Secondary analyses showed that increased exposure to court-based experiences and multiple forensic settings was associated with forensic fellowship interest.

This study demonstrates that a brief, mandatory forensic clinical rotation may increase residents’ exposure to forensic settings, assessments and courtroom-related experiences and that increased exposure to courtroom-based experiences in particular may increase interest in forensic fellowship. While not surprising, the results demonstrate that residents were not otherwise having these forensic experiences and that even time-limited forensic rotations can enhance the breadth of residents’ forensic exposures. Further, the rotation achieved these outcomes without using typical forensic sites but instead highly clinical sites, which may be particularly encouraging to residency programs without ready access to classic forensic rotation sites. This study contributes to the small but expanding body of the literature describing the value of increasing psychiatry residents’ training in clinical forensic psychiatry.

Mandatory auditor firm rotation (mandatory rotation) has been a controversial issue in the United States for many decades. Mandatory rotation has been considered at various times as a means of improving auditor independence. For example, in the United States, the Public Company Accounting Oversight Board (PCAOB) has considered mandatory rotation as a solution to the independence problem (PCAOB, 2011) and the European Parliament approved legislation that will require mandatory rotation in the near future (Council of European Union, 2014). The concept of implementing a mandatory rotation policy has been encouraged by some constituents of audited financial statements and rejected by other constituents of audited financial statements. Although there are apparent pros and cons of such a policy, the developmental process of such a policy in this country has not necessarily been an open-democratic, objective process. Universal mandatory rotation may or may not be the ideal solution; however, an open-democratic, objective process is needed to facilitate the development of a solution that considers the needs of all major stakeholders of audited financial statements – not simply accounting firms and public companies, but also investors. The purpose of this paper is to critically examine key issues relating to mandatory rotation and to encourage and stimulate future research and ongoing dialogue regarding this issue, in spite of efforts by certain constituents to silence the issue. This paper provides an overview of the various reasons, including practical, theoretical, political, and self-motivated reasons, why a mandatory rotation policy has not been implemented in the United States in order to address the potential conflict of interest between the auditor and client. This paper will also discuss how some deliberations of mandatory rotation have been flawed. The paper concludes with a summary of key issues along with two approaches for regulators, policy makers, and academics to consider as ways to improve the process and address auditor independence. The authors are not advocating for any specific solution; however, we are advocating for a more objective, unified approach and for the dialogue regarding auditor rotation to continue.

This study investigates the effects of vertical direction and rotation of English loan brand names in East Asian languages (Chinese and Korean) on processing fluency, perceived product quality and purchase intention.

Four experiments were conducted in China and Korea, employing a 2 (vertical direction: downward vs upward) X 3 (rotation: 0°/marquee vs 90° clockwise vs 90° counterclockwise) between-subjects factorial design.

The findings showed that when the English loan Chinese brand name was displayed downward, the marquee format was preferred, while counterclockwise rotation was favored when displayed upward. In Korean, clockwise rotation was preferred for downward presentation, while counterclockwise rotation was favored for upward presentation. The effects on purchase intention were mediated by processing fluency and perceived product quality.

This research provides practical implications for global manufacturers and retailers, offering guidance on presenting brand names in East Asian languages and optimizing product packaging designs. For Chinese consumers, the marquee format is recommended for downward-oriented brand names, while counterclockwise rotation is effective for upward orientation. For Korean consumers, clockwise rotation is favored for downward presentation and counterclockwise rotation is preferred for upward presentation. Understanding linguistic habits allows the tailoring of brand presentations, enhancing brand perception and consumer responses.

This study contributes to understanding the role of cultural and linguistic influences on consumer information processing and product perception in vertical presentations of brand names.

This study aims to examine the effects of allocation of audit hours to year-round audits and audit partners on audit quality when a new partner is appointed.

Using proprietary data of partners’ names and audit hours in the year-round context, the authors build a model testing input factors related to audit production and new partner assignment in 1,209 Korean listed firms during the period of 2015–2018.

The results show that in the partner rotation, the more audit hours spent, the more audit hours are allocated to the year-round audit, or more nonpartners’ audit hours are allocated to the year-round audit, the higher the audit quality. Subsample analyses show that these findings are concentrated in firms with longer audit tenure or low audit risk.

The findings may provide regulatory authorities with practical guidelines concerning partner rotation and how to allocate audit hours to different audit stages and ranks (partner vs staff).

To the best of the authors’ knowledge, this study provides the first evidence of the joint effects of partner rotation and audit hour allocation on audit quality.

This study aims to examine the relationships among structured-on-the job training (ST), mentoring, job rotation and the work environment factors on tacit knowledge transfer from training.

This study used quantitative research techniques to examine the causal relationships among the key study variables. A questionnaire-based survey has developed to evaluate the research model by drawing a convenience sample includes 239 employees working in the Arab Potash Company located in Jordan. Surveyed data were examined following the structural equation modeling procedures.

The results revealed that adapting of the ST, mentoring and job rotation in industrial firms had direct effect on the employees’ abilities to learn and transfer tacit knowledge from training to the actual work, and how these learning strategies strengthen employees’ abilities in solving work problems, improving customers’ satisfaction and quality of products and services. As well as, it affirmed the strong direct effect of work environment factors such as supervisor and peer support on the employees’ abilities to learning and transferring tacit knowledge to their jobs. However, this study showed that work environment factors have no significant mediating role on the relationship among ST, mentoring, job rotation and the employees’ abilities to learn and transfer tacit knowledge to their jobs.

The study results are opening the doors for future studies to examine the relationships among the methods of training and learning in the workplace, the work environment factors and tacit knowledge transfer from training to the jobs as prerequisites for improving the employees and organization performance. These results would be validated by conducting future research, examining larger samples of industrial companies to give more accurate data and clear explanations to the relationships among the study variables. It also suggests to replace the characteristics of work environment (supervisor support and peer support) by trainees’ characteristics (self-efficacy and career commitment) to give a better understanding to the relationships among the key study variables.

With regard to improving the employees’ competency while doing their jobs, this study developed a conceptual framework that guides managers to recognize the importance of ST, mentoring and job rotation in increasing the employees’ learning together; and giving them the chance to use the new learned experiences and knowledge to improve the organization performance and its competitive advantage. This study helps managers build a positive work environment that encourages social interaction, respect and mutual interest among employees, and increases their sense of responsibility for learning and transferring skills and knowledge to the jobs.

The training methods in the workplace go beyond immediate work performance to act as a promising tool make employees’ learning more easily and faster, and help them to transfer and retain new skills and knowledge, adapt with changing environments, build stronger relationships with stakeholders and at the same time, make the organizations ensure that employees comply with their societal goals.

The authors have noticed that large portions of the studies on training and human resources development neglected the role effect of (ST, mentoring and job rotation) on the tacit knowledge transfer from training to the jobs. Hence, these gaps in researches have motivated to develop a theoretical model that helps to examine the relationship between the two constructs. This study also suggests to examine the mediating role effects of work environment factors on the relationships among (ST, mentoring and job rotation) and tacit knowledge transfer, as well as it extends to examine the mediating role of work environment factors on transferring knowledge to jobs, attributed to the demographic variables such as gender, age, work experience and education level.

The swivel construction method is a specially designed process used to build bridges that cross rivers, valleys, railroads and other obstacles. To carry out this construction method safely, real-time monitoring of the bridge rotation process is required to ensure a smooth swivel operation without collisions. However, the traditional means of monitoring using Electronic Total Station tools cannot realize real-time monitoring, and monitoring using motion sensors or GPS is cumbersome to use.

This study proposes a monitoring method based on a series of computer vision (CV) technologies, which can monitor the rotation angle, velocity and inclination angle of the swivel construction in real-time. First, three proposed CV algorithms was developed in a laboratory environment. The experimental tests were carried out on a bridge scale model to select the outperformed algorithms for rotation, velocity and inclination monitor, respectively, as the final monitoring method in proposed method. Then, the selected method was implemented to monitor an actual bridge during its swivel construction to verify the applicability.

In the laboratory study, the monitoring data measured with the selected monitoring algorithms was compared with those measured by an Electronic Total Station and the errors in terms of rotation angle, velocity and inclination angle, were 0.040%, 0.040%, and −0.454%, respectively, thus validating the accuracy of the proposed method. In the pilot actual application, the method was shown to be feasible in a real construction application.

In a well-controlled laboratory the optimal algorithms for bridge swivel construction are identified and in an actual project the proposed method is verified. The proposed CV method is complementary to the use of Electronic Total Station tools, motion sensors, and GPS for safety monitoring of swivel construction of bridges. It also contributes to being a possible approach without data-driven model training. Its principal advantages are that it both provides real-time monitoring and is easy to deploy in real construction applications.

The purpose of this paper is to study the potential advantages of aircraft formation flight (FF) and to exploit further benefits through exchanging the leading positions.

The detailed and robust methodologies concerning FF mission analysis including the leading aircraft rotation strategies are developed in this paper to study the fuel burn benefit and the additional bonus of formation rotation.

Switch of FF leading positions can offset the undesired weight ratios between the leading and trailing aircraft within FF missions, which further alleviates the deviations from design flight conditions. The case studies on two long-range civil transport aircraft in FF show that the leading and trailing aircraft can achieve almost equal fuel benefit through rotations. As compared to FF without rotation, the fuel efficiency can be improved by more than 11 per cent.

The work can bring benefit the research communities as a fundamental basis for operational studies of FF, such as FF airspace management in the future, which is significant for a future real-world implementation of FFs.

According to the authors’ study, equal or quasi-equal fuel savings can be achieved if the rotation is properly arranged. For the real-world FF application, fuel consumption (FC) or cost redistribution problem for leading and trailing aircraft belonging to two different operating airlines can therefore be resolved through the concept proposed by the paper.

The methods developed in the paper have the advantage to give more reliable estimations of the achievable fuel burn savings of FF. The concept proposed in the paper has significant meaning with respect to offset the undesired weight ratios between the leading and trailing aircraft within FF missions and redistributing FC or cost redistribution of different operating airlines.
