Non-intrusive quantification of performance and its relationship to mood

The number of jobs that takes place entirely or partially in a computer is nowadays very signi cant. These workplaces, as many others, often o er the key ingredients for the emergence of stress and the performance drop of its long-term e ects: long hours sitting, sustained cognitive e ort, pressure from competitiveness, among others. This has a toll on productivity and work quality, with signi cant costs for both organizations and workers. Moreover, a tired workforce is generally more susceptible to negative feelings and mood, which results in a negative environment. This paper contributes to the current need for the development of non-intrusive methods for monitoring and managing worker performance in real time. We propose a framework that assesses worker performance and a case study in which this approach was validated. We also show the relationship between performance and mood.This work has been supported by COMPETE: POCI-01-0145-FEDER-007043 and FCT - Fundação para a Ciência e Tecnologia within the Project Scope: UID/CEC/00319/2013.

Direct and indirect effects of mood on risk decision making in safety-critical workers

The study aimed to examine the direct influence of specific moods (fatigue, anxiety, happiness) on risk in safety-critical decision making. It further aimed to explore indirect effects, specifically, the potential mediating effects of information processing assessed using a goodness-of-simulation task. Trait fatigue and anxiety were associated with an increase in risk taking on the Safety-Critical Personal Risk Inventory (S-CPRI), however the effect of fatigue was partialled out by anxiety. Trait happiness, in contrast was related to less risky decision making. Findings concerning the ability to simulate suggest that better simulators made less risky decisions. Anxious workers were generally less able to simulate. It is suggested that in this safety-critical environment happiness had a direct effect on risk decision making while the effect of trait anxiety was mediated by goodness-of-simulation

Improving office users' workplace perceptions using plants

This paper explores the importance of user perceptions within an organisational context, and more specifically, aims to identify and demonstrate the benefits of plants in offices in contributing to employee wellbeing by influencing their perceptions of a working office. Via comprehensive literature reviews, the importance of user perceptions is determined as well as the importance of indoor plants in office environments in improving employee wellbeing through psychological benefits. It is argued that user perceptions can be analysed through their input and functionalities in the workplace and their consequent application of workplace productivity. In this study, a perception survey was completed, which demonstrated that occupants of planted offices feel more comfortable, more productive, healthier and more creative and feel less pressure than occupants of non-planted offices. The paper provides an insight into how plants can be incorporated within facilities management strategies to improve employee health and wellbeing and improve perceived productivity

Nootropics use in the workplace. Psychiatric and ethical aftermath towards the new frontier of bioengineering

OBJECTIVE: The authors have sought to expound upon and shed a light on the rise of nootropics, which have gradually taken on a more and more relevant role in workplaces and academic settings. MATERIALS AND METHODS: Multidisciplinary databases have been delved into by entering the following keys: "nootropics", "cognitive enhancement", "workplace", "productivity", "ethics", "bioengineering". In addition, a broad-ranging search has been undertaken on institutional websites in order to identify relevant analysis and recommendations issued by international institutions and agencies. Papers and reports have been independently pored over by each author. This search strategy has led to the identification of 988 sources but only 64 were considered appropriate for the purposes of the paper after being selected by at least 3 of the authors, independently. RESULTS: The notion of an artificially enhanced work performance - carried out by the 'superworker' - is particularly noteworthy and resonates with the conception of contemporary work on so many different levels: the rising need and demands for higher degrees of flexibility and productivity on the job, the implications of a '24/7' society, where more and more services are available at any time, the ever greater emphasis on entrepreneurial spirit, individual self-reliance and self-improvement, and last but not least, the impact of an ageing society on economic standards and performance. CONCLUSIONS: Moreover, it is worth mentioning that human enhancement technologies will predictably and increasingly go hand in hand with gene editing, bioengineering, cybernetics and nanotechnology. Applications are virtually boundless, and may ultimately affect all human traits (physical strength, endurance, vision, intelligence and even personality and mood)

The Influence of Occupational Driver Stress on Work-related Road Safety: An Exploratory Review

Research has identified a number of stressors that could impact on the occupational driver by increasing stress levels and, for some individuals, causing adverse behaviour and effects, for example, aggressive behaviour, fatigue, inattention/distraction, and substance abuse. For safety professionals and employers, one way to reduce the effects of occupational driver stress is to change perceptions so that management and drivers recognise that work-related driving is as important as other work-related tasks. This article explores relevant literature in relation to driver stress and suggests additions to risk management processes and safety procedures/policies, including assigning sufficient basic resources to target occupational stress (particularly occupational driver stress)

Evaluation of the Workplace Environment in the UK, and the Impact on Users’ Levels of Stimulation

The purpose of this study is to evaluate a number of recently completed workplaces in the UK. The first aim is to assess the impact of various aspects of the workplace environment on users’ levels of stimulation. The body of previous research undertaken into the workplace environment, identified the aspects to be investigated. Samples of employees from the sixteen businesses were surveyed to determine their perceptions of the workplaces. The results were entered into a regression analysis, and the most significant predictors of perceived stimulation identified. The data also revealed a dramatic reduction in staff arousal levels from mornings to afternoons. Thus, there is a second aim to determine whether changes to significant aspects of the workplace environment during the day can counteract the reduction in users’ stimulation. Two further workplaces were studied to enable changes to be made over a 12-week period. A sample of employees completed questionnaires, and semi-structured interviews revealed the reasons behind the results. It was found that provision of artwork, personal control of temperature and ventilation and regular breaks were the most significant contributions to increasing stimulation after lunch; while user choice of layout, and design and décor of workspaces and break areas, were the most significant aspects at design stage

Green exercise as a workplace intervention to reduce job stress: results from a pilot study

Stress and mental fatigue are major health threats to employees in office-based occupations. Physical activity is widely used as a stress-management intervention for employees. Moreover, experiences in contact with nature have been shown to provide stress-reduction and restoration from mental fatigue. OBJECTIVES:In a pilot study designed as a randomized controlled trial we investigated the impact of a green-exercise intervention on psychological and physiological indicators of stress in municipality employees. METHODS:Fourteen employees (7 females and 7 males, 49±8 yrs) volunteered in an exercise-based intervention in workplace either outdoors in a green/nature area or in an indoor exercise-setting. The intervention consisted of an information meeting and two exercise sessions, each including a biking bout and a circuit-strength sequence using elastic rubber bands (45-minutes, at about 55% of HR reserve, overall). Main outcomes were perceived environmental potential for restoration, affective state, blood pressure (BP) and cortisol awakening response (CAR AUCG and CAR AUCI) and cortisol levels in serum. Measurements were taken at baseline and in concomitance with the exercise sessions. Furthermore, affective state and self-reported physical activity levels were measured over a 10-weeks follow-up period. RESULTS:Compared with the indoor group, the nature group reported higher environmental potential for restoration (p <  0.001) and Positive Affect (p <  0.01), along with improved CAR AUCI (p = 0.04) and, marginally, diastolic BP (p = 0.05). The nature group also reported higher ratings of Positive Affect at follow-up (p = 0.02). Differences at post-exercise were not found for any of the other components of affective state, systolic BP, CAR AUCG and cortisol levels measured in serum. CONCLUSIONS:Green-exercise at the workplace could be a profitable way to manage stress and induce restoration among employees. Further studies on larger samples are needed in order to improve the generalizability of the results

Relationships between exercise and three components of mental well-being in corporate employees

Objectives: The main purpose of the present study was to examine the relationships between exercise participation and three components of mental well-being (physical self, work-related, and global) in a sample of corporate employees. As a subsidiary and exploratory question, we also examined whether these well-being components are more strongly related to structured exercise participation scores compared to total levels of physical activity. Design: Cross-sectional survey. Method: The participants were 312 employees from an information technology company (nZ204 males and nZ108 females). Structural equation modelling was used to examine links between exercise participation and the three well-being components within a hierarchical framework, featuring global well-being constructs at the apex and specific elements of well-being at lower levels. Results: Support was found for the a priori model in that there were direct paths from exercise to physical self and enthusiasm at work. Furthermore, there were indirect paths between exercise and global well-being components through measures of the physical self and enthusiasm at work. The results of an alternative model using physical activity as opposed to exercise were generally similar. Conclusion: The support found for the exercise and well-being model indicates that exercise is associated directly and indirectly with high well-being in various facets of employees’ lives. Thus, this study extends previous research that has examined associations between exercise and isolated indicators of employee well-being. Finally, the results pertaining to physical activity suggest that workplace exercise promotion programmes should incorporate and promote lifestyle physical activity

Neuroinclusive workplaces and biophilic design: Strategies for promoting occupational health and sustainability in smart cities

This study aims to investigate the impact of biophilic design on occupational health and productivity, with a particular focus on addressing the needs of diverse populations, including the neurodiverse, during the post-pandemic return to work. With an estimated 15 – 20% of the global population considered neurodiverse, it is crucial to understand and accommodate their specific needs, such as those with attention-deficit hyperactivity disorder, autism spectrum condition, and learning disabilities. These individuals face increased occupational stress, necessitating the development of targeted strategies. The renewed interest in sustainability and employee well-being has led to a resurgence of biophilic design in the workplace. Grounded in the concept that humans possess an inherent inclination to affiliate with nature, the biophilic design integrates natural elements and art into the built environment. This integration has been found to reduce activity in the amygdala, promoting stress recovery, prolonged attention, and increased productivity among employees. To effectively acclimate neurodiverse individuals in the work environment, biophilic design should be complemented using extended reality (XR) technology supported by artificial intelligence. Virtual reality, in particular, has been shown to facilitate individuals’ comfort in new workspaces, aid in self-assessments through biofeedback, and enable the adjustment of surroundings for self-regulation. Furthermore, biophilic design has the potential to promote sustainability in smart cities by integrating natural elements into the built environment. This integration helps reduce the carbon footprint of buildings and enhances energy efficiency. By creating workplaces that prioritize biophilic design principles, organizations can contribute to a more inclusive, sustainable, and productive work environment
