We examine the influence of the self-assessment and self-enhancement motives on the choice of comparison organizations in two experimental studies. Study 1 shows that: (1) self-assessment generally prevailed over self-enhancement, guiding decision makers to choose organizations that were more similar and had better performance; (2) self-enhancement was more pronounced under conditions of low performance, leading participants to more frequently choose organizations that were less similar and had lower performance; and (3) self-enhancing comparisons inhibited perceptions of failure and the propensity to make changes. Study 2 extends the results of Study 1 by showing that participants were more likely to choose comparison organizations that had lower performance and were less similar when they were in a self-enhancement mindset than when they were in a self-assessment mindset. The combined effects of self-assessment and self-enhancement on the choice of comparison organizations are discussed in relation to the broader organizational literature on learning from performance feedback.

The purpose of this paper is to show that in comparison to performance appraisal, “practice enhancement” is offered as a conceptual tool that can be used to develop strategies for reflecting on, communicating changes in and planning for excellence in teaching practice.

The conceptual notion of practice enhancement is underpinned by assumptions from the discipline of positive psychology and supported by the need for a performance management process targeting teaching practice that considers the contributions made by social learning theory and organisational learning theory. Indicative of a postmodern persuasion, a data “story” from case study research is used to support the applicability of practice enhancement in schools. Actor‐network theory is used to analyse movements in local professional learning preferences and practices in an independent boys' school in Australia.

The paper finds that applicability and conceptual accuracy of managerial notions such as performance appraisal should be critically considered by educational researchers, policymakers, school leaders and teaching practitioners when developing processes for managing the performance of teachers in schools.

Empirical studies evaluating the effectiveness of performance management processes underpinned by the notion of performance enhancement (in schools and other workplace settings) are required.

A conceptual tool for guiding the development of processes and tools for managing teaching excellence is provided.

This paper draws on cross‐disciplinary knowledge and the work of teaching practitioners to provide recommendations for cultivating conditions that enable teaching excellence.

Quality assurance (QA) at one University has evolved over the past 15 years through emerging National and European standards, various leadership initiatives and through the engagement of key stakeholders in co-designing and implementing internal QA processes. In 2000, the QA process was focussed mainly on quality review (QR) that involved extensive reporting of information. It was characterised by stakeholders as a largely reactive culture, treated with scepticism by faculty staff and that struggled to convince both management and faculty that QA provided value. In 2016, QR is now leaner, more evidence based and focussed around creativity and enhancement. In addition to QR, additional QA processes now incorporate a variety of activities including benchmarking, structured policies and procedures and research assessment. QA is also part of a tripartite approach that links quality, strategy and performance together, with quality focusing on assuring an appropriate standard of excellence, strategy guiding faculty towards a vision of the future and performance providing evidence of quality enhancement and strategy execution. The paper provides a case study of the transformation of QA at the University.

The research uses a case study approach. It documents a methodology used to engage a wide number of stakeholders in a self-evaluation process and the results of that process, i.e. enhancements to the internal review process and various policies and procedures.

There are early indications that the University’s internal QA has migrated towards a more responsive culture and is increasingly endorsed by the various internal and external stakeholder groups.

This paper presents the evolution of QA and potential lessons for the wider Higher Education Institutions (HEI’s) sector.

This paper provides a case study of changes to QA processes at one university that has risen significantly in various university rankings since. Some evidence is provided to show that quality initiatives have contributed to overall performance.

The purpose of this paper is to enhance the heat transfer and thermal performance in the trailing edge region of the vane with vortex generators (VGs).

This numerical study presents the enhancement of thermal performance in the trailing part of a gas turbine blade. In the trailing part, generally, pin fins are used either in staggered or in-line arrangements to enhance the heat transfer. In this study, based on the idea from heat exchangers, pin fins are combined with VGs. A pair of VGs is embedded in the boundary layer upstream of each pin fin in the first row of the pin fin array having an in-line configuration. The effects of the VG angle relative to the streamwise direction and streamwise distance between the pin fin and VGs are investigated at various Reynolds numbers.

The results indicated that the endwall heat transfer is enhanced with the addition of VGs and the heat transfer from the surfaces of the pin fins. The level of heat transfer enhancement compared to the case without VGs is more significant at high Reynolds number. The surfaces of the VGs also show a significant amount of heat transfer. Study of the angle of the attack suggested that a high angle of attack is more appropriate for pin fin cooling enhancement whereas an intermediate gap between the VGs and pin fins shows considerable improvement of thermal performance compared to the small and large gaps. The phenomenon of heat transfer augmentation with the VGs is demonstrated by the flow field. It shows that the enhancement of heat transfer is governed by the mixing of the flow as a result of the interaction of vortices generated by the VGs and pin fins.

VGs are used to disturb the thermal boundary layer. It shows that heat transfer is augmented as a result of the interaction of vortices associated with VGs and pin fins.

This paper aims to examine the use of Cross-Functional Bridge (CFB) in dyadic relationships towards enhancing organisational performance. Prior research has flagged conflict in interfunctional relationships. Research on managing such conflict context is, however, limited.

Analysing 20 in-depth interviews conducted in UK financial services organisations, this study explains how the CFB is used to manage interfunctional relationship conflict and enhance performance.

This study underlines three core insights about intragroup working relationship: cultural and disciplinary differences and boundary fencing are core features of, and conflict drivers in, the accounting – marketing interface; CFB is a tool for analysing and managing these conflict drivers; and organisations that use this tool achieve improved organisational performance, an outcome that is enhanced and sustained through the team psychological enhancement factor of the conflict management strategy. Also, this study underlines the need to ensure a fit between conflict management strategy and conflict types.

This research has several limitations. It explores only accounting – marketing working relationship in UK financial services organisations. Also, it explores only relationship conflict and cultural and disciplinary diversity and boundary fencing factors. Finally, this study suggests a mediating influence of psychological well-being on the CFB – performance link, a conclusion that is based on a methodologically inadequate tool: causes and effects associations are better assessed quantitatively (Johnson and Onwuegbuzie, 2004).

The paper highlights insights for analysing and resolving conflicts towards harmonious dyadic relationships. Importantly, managers who use the flagged CFB tool would achieve psychological enhancement in team, and extendedly enhanced organisational performance. Managers are reminded of the need to adequately address the emotional substances in relationship conflicts, as failure to do this will lead to conflict escalation, transformation and negative performance.

The paper offers theory testing and theory building knowledge. The CFB insight is a major highlight, one that lays a brick for future development, especially concerning its modus operandi, motivators and how to maximize its performance value.

The purpose of this paper is to examine the relationships of service marketing mix (SMM) as service input and service output in terms of students’ performance, satisfaction and referral act in context to higher and technical education (HTE) through the application of structural equation modeling.

A quantitative research, conducted through a self-administered survey composed by a closed-ended structured questionnaire, was incorporated for the students who were enrolled in the technical educational institutions situated in the Khandesh region of India.

The findings of this study revealed that traditional SMM is statistically linked with the performance of students in terms of skill and knowledge enhancement, satisfaction and referral act of students, which are perceptible new emerging SMM; performance, pleasure and pointing out in terms of service output.

Integrating SMM as service input and service output are productive for HTE in enhancing growth (quantitatively) by the inclusivity of diversified students and development (qualitatively) by enhancing their performance for global standing, making them satisfied and motivating them for recommending their institution to others. This integration can be utilized as a yardstick by the institutions for staying ahead in students’ market with a distinctive competitive advantage.

Growth and development of HTE will raise a society’s quality of life and thereby increase a country’s socio-economic status.

The study has exhibited SMM as input and output of a service system that is useful for the growth and development of HTE. The measurement tool presented is effective in (re)framing policies on SMM as service input based on desired service output.

The White Paper on Local Government in South Africa signals the intention to establish a performance management system for the sector. This paper suggests that current approaches to performance management, as used, for instance, in the UK public sector, would need substantial revision to be supportive of effective municipal development in South Africa. There is a need for low cost systems that fit the capabilities of the administrations that exist in many municipalities. A focus upon how municipalities manage their governance role would in the end be the best way of ensuring that liveable communities as well as improved services are created in the towns and rural areas of South Africa. The paper provides some ideas on the design of such a performance management or enhancement system. Its principal features would be that it is: based on mutual organisational learning and problem solving; using simple, indirect, low cost information gathering and dissemination techniques that are within the capabilities of existing leaders and officials; focused on processes in priority to outcomes.

The purpose of this paper is to investigate a cylindrical flow insert for a parabolic trough solar collector. Centrally placed and eccentric placed inserts are investigated in a systematic way to determine which configuration leads to the maximum thermal enhancement.

The analysis is performed in SolidWorks Flow Simulation with a validated computational fluid dynamics model. Moreover, the useful heat production and the pumping work demand increase are evaluated using the exergy and the overall efficiency criteria. The different scenarios are compared for inlet temperature of 600 K, flow rate of 100 L/min and Syltherm 800 as the working fluid. Moreover, the inlet temperature is examined from 450 to 650 K, and the diameter of the insert is investigated up to 50 mm.

According to the final results, the use of a cylindrical insert of 30 mm diameter is the most sustainable choice which leads to 0.56 per cent thermal efficiency enhancement. This insert was examined in various eccentric positions, and it is found that the optimum location is 10 mm over the initial position in the vertical direction. The thermal enhancement, in this case, is about 0.69 per cent. The pumping work demand was increased about three times with the insert of 30 mm, but the absolute values of this parameter are too low compared to the useful heat production. So, it is proved that the increase in the pumping work is not able to eliminate the useful heat production increase. Moreover, the thermal enhancement is found to be greater at higher temperature levels and can reach up to 1 per cent for an inlet temperature of r650 K.

The present work is a systematic investigation of the cylindrical flow insert in a parabolic trough collector. Different diameters of this insert, as well as different positions in two dimensions, are examined using a parametrization of angle-radius. To the authors’ knowledge, there is no other study in the literature that investigates the presented many cases systematically with the followed methodology on parabolic trough collectors. Moreover, the results of this work are evaluated with various criteria (thermal, exergy and overall efficiency), something which is not found in the literature.

The purpose of this paper is to investigate the enhancement of the performance of bubble absorber using hybrid nanofluid as a cooled NH₃/H₂O absorption system to reduce their size and to find the best fitting model. A numerical model for ammonia-water bubble absorber was developed to show the influence of operating conditions and design parameters on the absorber performance.

A finite difference numerical method is used to solve the numerical model. The model is subjected to the inlet conditions of liquid, vapor and coolant flow regimes. The absorber modeling was divided into small elements along the absorber length.

The model proposed is validated with previously published works. Then agreement between the both is considered as good.

Numerical results/The use of hybrid nanofluids.

The results showed that the hybrid nanofluid is the best cooling medium. Very high heat transfer rates are obtained because of the high thermal conductivity and specific heat of hybrid nanofluid, and consequently, the absorber size decreases. It was also found that the absorber thermal load and the mass absorption flux increase with increasing of solid volume fraction. Also, the existence of an optimal absorber length was revealed, required for complete absorption when using hybrid nanofluid as a cooling medium. It is recommended that using hybrid nanofluid to remove the heat from the absorber is the best candidate for NH₃/H₂O absorption performance enhancement.
