This study aims to investigate the hybridization practices that medical managers engage with to promote accounting and performance measurement in the hybrid setting of healthcare. In doing so, the authors explore how medical managers enact and become practitioners of hybridity.

The authors adopt a practice lens to conceptualize hybridization as an emergent, situated practice and capture the micro-activities that medical managers engage with when they enact hybridity. The authors conducted semi-structured interviews with medical managers, business managers and coding professionals and collected documents at an English National Health Service (NHS) hospital over the course of five years.

The findings accentuate two emergent practices through which medical managers instill hybridity to individuals who are hesitant or resistant to hybridization. Medical managers engage in equivocalizing and de-stigmatizing practices to broaden the understandings, further diversify or reconcile the teleologies of clinicians in non-managerial roles. In doing so, the authors signal the merits of accounting in improving care outcomes and remove the stigma associated to clinical engagement with costs.

The study contributes to hybridization and practice theory literature via capturing how hybridity is enacted in practice in a healthcare setting. As medical managers engage with and promote accounting information and performance measurement technologies in their practice environment, they transcend professional boundaries and hybridize the professional spaces that surround them.

In the current digital era where online content is riddled with fabricated metrics and rankings, this research aims to investigate the underpinning mechanisms of the calculative practices which actors engage with to evaluate digital platform content in the absence of well-defined performance measures.

The paper focuses on the online, photo-sharing platform Instagram which is devoid of common performance measures such as rankings, ratings and reviews. The authors applied netnographic methods to capture users' actions and interactions at the Greek Instagram community. The authors adopt a practice lens as informed by Schatzki's ‘site ontology’ to capture actors' calculative practices as organised by rules, teleoaffective structures and general and practical understandings.

Platform actors engage in aesthetic and palpable evaluations of other user profiles and their posted content. They employ permissible (e.g., using third-party apps) and illicit (e.g., lobbying and procuring engagement) tactics to measure and manage digital platform performance, fabricate metrics and blur others' evaluations, in pursuit of prestige and material teleologies. Their calculative practices are conditioned by an implicit social etiquette, which permeates the platform both horizontally and vertically.

First, the paper captures and theorises the mechanisms which underpin actors' calculative practices for performance measurement in the absence of robust judgement devices. Second, it demonstrates how ambiguous assemblages of material and prestige teleologies, aesthetic and palpable evaluative regimes and implicit rules and practical expertise collectively invoke platform actors' calculative practices and the construction of performance measures. In doing so, it contributes to performance measurement literature via demonstrating how management accounting is implicated in the evaluation of digital platform outputs.

The paper provides insight on how platform actors fabricate performance metrics, what they perceive as ‘good’ online content and what constitutes an ‘impactful’ user account or a ‘successful’ social media campaign. Such findings are valuable to management accountants, entrepreneurs and practitioners who seek to evaluate digital platform performance.

Health-related quality of life (HRQOL) is a subjective multi-dimensional concept referring to an individual’s perception of health and well-being in domains related to physical, mental, emotional and social functioning. The current study aims at investigating possible associations between dietary quality, disordered eating attitudes and HRQOL in Greek adolescents.

A total of 400 students (198 boys; 202 girls), 14-17 years old, were recruited from five high schools in the area of Kallithea in Athens, Greece. Standard anthropometric measurements were taken, and obesity classification was conducted using the International Obesity Task Force (IOTF) cut-off points. Students completed the KIDMED index, which evaluates the degree of adherence to the Mediterranean diet (MedDiet) as a diet quality index, the EAT-26 questionnaire, which assesses disordered eating attitudes and the KIDSCREEN-27 questionnaire for children and adolescents assessing perceived HRQOL.

Disordered eating attitudes are significantly negatively correlated with the total score of HRQOL (p < 0.01) and with the subcategories: psychological well-being (p < 0.01), parents and autonomy (p < 0.01) and school environment (p < 0.001), whereas adherence to the MedDiet was positively correlated with all the components and total score of HRQOL. Linear regression analysis revealed that adherence to the MedDiet (p < 0.05), total number of meals/day (p < 0.01) and number of meals with the family (p < 0.05) were significant predictors of HRQOL in adolescents.

The convenient sampling of 400 students was conducted from five schools, from one municipality of Athens, Greece.

Adherence to the MedDiet positively affects important components of HRQOL in adolescents, whereas disordered eating attitudes has a negative effect. Identifying adolescents with low HRQOL is highly important because it could result in an early detection of individualised healthcare needs and possible non-diagnosed ill-health problems.
