Abstract
Purpose
This paper explores how performance-management systems are understood and framed through the use of rhetoric and language within universities, where not-for-profit, charitable goals are (or should be) central. It addresses the issues of: how strategic rhetorical frames are used by university actors; and how these relate to actors' primary frames and reactions to performance-management practices. The study focuses on the case of UK universities, taking into consideration both old and newer institutions.
Design/methodology/approach
This study adopts a case-study approach, relying on 28 interviews with key-academic actors involved in the design and implementation of university performance-management systems in four UK universities.
Findings
The research highlights the important effect of primary frames over the strategic frames that are mobilised to achieve desired outcomes or individual advantage. In Business disciplines, the consistency between actors' primary frames and managerial and performance-management tools introduced into universities makes such disciplines a fertile ground for these practices to be embraced. This is not the case with Natural Sciences.
Practical implications
While framing a new practice consistently with existing/prevailing primary frames may be a winning strategy in the short term, in the long term, those tasked with introducing new practices should consider that the prevalence of a certain view of the world has the potential to hamper innovation and learning.
Originality/value
The paper contributes to advance our understanding of the interaction between individual primary and strategic frames, as well as academic staff's reactions and interpretations of performance-management practices in universities as knowledge-intensive, not-for-profit organisations.

Abstract
Purpose
This study aims to propose an aerodynamic force decomposition which, for the first time, allows for thrust/drag bookkeeping in two-dimensional viscous and unsteady flows. Lamb vector-based far-field methods are used at the scope, and the paper starts with extending recent steady compressible formulas to the unsteady regime.
Design/methodology/approach
Exact vortical force formulas are derived considering inertial or non-inertial frames, viscous or inviscid flows, fixed or moving bodies. Numerical applications to a NACA0012 airfoil oscillating in pure plunging motion are illustrated, considering subsonic and transonic flow regimes. The total force accuracy and sensitivity to the control volume size is first analysed, then the axial force is decomposed and results are compared to the inviscid force (thrust) and to the steady force (drag).
Findings
Two total axial force decompositions in thrust and drag contributions are proposed, providing satisfactory results. An additional force decomposition is also formulated, which is independent of the arbitrary pole appearing in vortical formulas. Numerical inaccuracies encountered in inertial reference frames are eliminated, and the extended formulation also allows obtaining an accurate force prediction in presence of shock waves.
Originality/value
No thrust/drag bookkeeping methodology was actually available for oscillating airfoils in viscous and compressible flows.

Abstract
Purpose
Blockchain is a disruptive technology that has matured to deliver robust, global, IT systems, yet adoption lags predictions. The authors explore barriers to adoption in the context of a global challenge with multiple stakeholders: integration of carbon markets. Going beyond the dominant economic-rationalistic paradigm of information system (IS) innovation adoption, the authors reduce pro-innovation bias and broaden inter-organizational scope by using technological frames theory to capture the cognitive framing of the challenges perceived within the world’s largest carbon emitter: China.
Design/methodology/approach
Semi-structured interviews with 15 key experts representing three communities in China’s carbon markets: IT experts in carbon markets; carbon market experts with conceptual knowledge of blockchain and carbon market experts with practical blockchain experience.
Findings
Perceived technical challenges were found to be the least significant in explaining adoption. Significant challenges in five areas: social, political legal and policy (PLP), data, organizational and managerial (OM) and economic, with PLP and OM given most weight. Mapping to frames developed to encompass these challenges: nature of technology, strategic use of technology and technology readiness resolved frame incongruence that, in the case explored, did not lead to rejection of blockchain, but a decision to defer investment, increase the scope of analysis and delay the adoption decision.
Originality/value
Increases scope and resolution of IS adoption research. Technological frames theory moves from predominant economic-rational models to a social cognitive perspective. Broadens understanding of blockchain adoption in a context combining the world’s most carbon emissions with ownership of most blockchain patents, detailing socio-technical challenges and delivering practical guidance for policymakers and practitioners.

Abstract
Purpose
The purpose of this study is to find the suitable trajectory path of the Numerical model of the Quadcopter. Quadcopters are widely used in various applications due to their compact size and ease of assembly. Because they are quite unstable, autonomous control systems would be used to overcome this problem. Modelling autonomous control is predominant as the research scope faces challenges because of its highly non-linear, multivariable system with 6 degree of freedom.
Design/methodology/approach
Quadcopters with antonym systems can operate in an unknown environment by overcoming unexpected disturbances. The first objective when designing such a system is to design an accurate mathematical model to describe the dynamics of the system. Newton’s law of motion was used to build the mathematical model of the system.
Findings
Establishment of the mathematical model and the physics behind a four propeller drone for the frame TAROT 650 carbon was done. Simulink model was developed based on the mathematical model for simulating the complete dynamics of the drone as well as location and gusts were included to check the stability.
Originality/value
The control response of the system was simulated numerically results are discussed. The trajectory path was found. The phases with their own parameters can be used to implement the mathematical model for another type of quadcopter model and achieve quick development.

Abstract
Purpose
This paper offers a critical discussion to contribute to sociological work by emphasizing deconstruction(s) of the markers of gendered and racialized borders and epistemological injustice(s) in theory and practice of contemporary global frames of representation and women's intersectional identities and rights. Through a postcolonial, situated feminist approach, the theoretical framework aims to scope and review literature from the South and North.
Design/methodology/approach
The research employs a mixed-methodology of a survey paper and media critical discourse analysis of media monitoring frames of Egyptian women's rights post–Arab spring. The content, layout and imageries produced by representations are assessed to explore whether there are lingering subtle and blatant hints of continued orientalism in knowledge canons.
Findings
The underlying causes for misconceptions and reductionist sociopolitical attitudes may be styled by patriarchal and orientalist imposition and are highly found to be somewhat maintained by persistent Western-centric epistemologies claiming to define or speak for the so-called other. The above-mentioned structures are evidently channelled through languages which essentialize and control women of the South, urging for further research in knowledge canons which calls oppressive frames into question.
Originality/value
More feminist contributions from non-Western gazes are needed to fill gaps in canons of knowledge and deconstruct patriarchal and colonial codes which impose inequalities on women as seen through the survey paper of theoretical representation and media politics.

Abstract
Purpose
This paper aims to explore the important role boundaries play in back-office framing of environmental engagement. This is of particular interest because it is not clear how organizations in an industry without standardized environmental reporting navigate their boundaries behind the scenes and why they engage with the environment the way they do. This element of their environmental identity offers important insights into the emergence of sustainability reporting.
Design/methodology/approach
Guided by Miles and Ringham (2019) the authors conduct an ethnography of the Montana ski industry. The ethnography includes extensive on-site observations at nine Montana ski areas and interviews with 16 ski area executives, two regulators and a land development executive.
Findings
The authors find three key boundaries – accountability structure, degree of regulatory burden and impact measurement approach – that shape the back-office economic and environmental framing of ski executives (Goffman, 1959, 1974). From these back-office frames the authors identify four front-office cultural performances – community ecosystem, quantitative ownership, approval seeking and advocacy platform – that represent the environmental engagement strategies at these resorts.
Practical implications
Understanding the relationships between boundaries and environmental engagement is an important step in developing appropriate industry-wide environmental accountability and sustainability expectations. The study’s findings extend to other industries that are both highly dependent on the environment and are in the early stages of developing environmental reporting standards.
Originality/value
Ski resorts operate in an industry that is impacted by changes in the natural environment. The authors chronicle the process by which boundaries lead to framing which leads to environmental engagement in this weather-dependent industry. The authors explain the process of environmental identity building, the result of which both precedes environmental reporting and puts such reporting into context. In this sense, the authors show how boundaries are set and maintained in the ski resort industry, and how fundamental these boundaries are to the development of individual companies' environmental engagement strategies.

Abstract
Purpose
This paper aims to examine how CEO talk of sustainability in CEO letters evolves in a period of increased expectations from society for companies to increase their transition towards becoming more sustainable and to better account for progress and performance within the sustainability areas.
Design/methodology/approach
By adopting an interpretive textual approach, the paper provides a careful analysis of how CEO talk of sustainability in CEO letters of large listed Swedish companies developed during 2008–2017.
Findings
The talk of sustainability is successively becoming more elaborated, proactive and multidimensional. CEOs frame their talk by adopting different perspectives: the distinct environmental, the performance and meso, the product-market-oriented and the sustainability embeddedness and value creation. The shift towards an embeddedness and value-creation perspective in the later letters implies that the alleged capitalistic and short-sighted focus on shareholder value maximisation might be changing towards a greater focus on sustainability embeddedness as an important goal for succeeding with the transition towards a sustainable business.
Practical implications
The findings are relevant for policymakers and government bodies when developing policies and regulations aimed at improving the positive impact of companies on global sustainable development. Findings are also useful for management teams when structuring their sustainability talk as a response to external pressure.
Social implications
The findings provide relevant input on how social norms, values and expectations are shaping the corporate discourse on sustainability.
Originality/value
The findings of this study contribute to an increased understanding of the rhetorical response in influential CEO letters to the surrounding sustainability context, including new national and international policies as well as sociopolitical events and discourses related to sustainability. This offers a unique frame of reference for further interpretational work on how CEOs frame, engage in and shape the sustainability discourse.

Abstract
Purpose
Docking technology plays a crucial role in enabling long-duration operations of autonomous underwater vehicles (AUVs). Visual positioning solutions alone are susceptible to abnormal drift values due to the challenging underwater optical imaging environment. When an AUV approaches the docking station, the absolute positioning method fails if the AUV captures an insufficient number of tracers. This study aims to to provide a more stable absolute position visual positioning method for underwater terminal visual docking.
Design/methodology/approach
This paper presents a six-degree-of-freedom positioning method for AUV terminal visual docking, which uses lights and triangle codes. The authors use an extended Kalman filter to fuse the visual calculation results with inertial measurement unit data. Moreover, this paper proposes a triangle code recognition and positioning algorithm.
Findings
The authors conducted a simulation experiment to compare the underwater positioning performance of triangle codes, AprilTag and Aruco. The results demonstrate that the implemented triangular code reduces the running time by over 70% compared to the other two codes, and also exhibits a longer recognition distance in turbid environments. Subsequent experiments were carried out in Qingjiang Lake, Hubei Province, China, which further confirmed the effectiveness of the proposed positioning algorithm.
Originality/value
This fusion approach effectively mitigates abnormal drift errors stemming from visual positioning and cumulative errors resulting from inertial navigation. The authors also propose a triangle code recognition and positioning algorithm as a supplementary approach to overcome the limitations of tracer light positioning beacons.

Abstract
When implemented effectively and systematically across a curriculum, high impact practices (HIP) have the potential to increase student engagement and result in higher student achievement. The United States Air Force Academy (USAFA) is a four-year military university with a large liberal education core curriculum that provides the foundation for service and officership in the United States Air or Space Forces. Building on the liberal education core, the civil engineering (CE) major’s courses begin with the cornerstone field engineering course, paired with a two-week co-curricular experience for students at an Air or Space Force installation. With its motto “construct first, design later,” the field engineering course is an HIP and quintessential experiential learning course that gives students a practical frame-of-reference for future analysis and design courses. The CE major culminates with another HIP, the capstone design course, which gives students the opportunity to demonstrate their skills, building confidence in their ability to successfully apply those skills to the increasingly complex problems they will face after graduation. This book chapter provides a case study of the CE major at the USAFA, documenting the HIPs across the majors’ program, and highlighting the key elements and benefits of each.
