This paper aims to determine the extent to which employees’ experiences of acoustic comfort, well-being and productivity in open-plan offices are determined by specific characteristics (including demographic information, task characteristics, and personality traits).

A questionnaire was distributed to the occupants of three open-plan office sites and was completed by 166 employees in total.

The results indicated that acoustic comfort in open-plan offices is largely determined by noise sensitivity. Higher noise sensitivity was associated with more negative ratings of acoustical quality, more perceived disturbance by speech and more difficulties in concentration. More negative experiences were also reported by employees with lower interactivity with colleagues.

There is significant inter-individual variability in experiences of acoustic comfort, well-being and productivity in open-plan offices. As such, workplace practitioners should consider acoustic and behavioural solutions for introducing a greater diversity of functional workspaces within the office, so that employees can choose the most suitable working area for their requirements.

Whereas the majority of past acoustics research has been laboratory-based, this study is conducted in real office environments with a representative sample of knowledge workers.

There has been limited investigation into how “biophilic design” (i.e. the integration of nature within the built environment) can be effectively used within the workplace to facilitate the process of psychological restoration. The purpose of this study was to focus, in particular, on the effectiveness of biophilic “restoration pods” in promoting recovery from stress.

A randomised field experiment was conducted. A total of 32 employees from a participating organisation completed two tests replicating typical office work (proofreading and arithmetic) and subjective ratings of stress, anxiety and task-load both before and after a 10-minute micro-break, taken in either the regeneration pods (treatment group) or an ordinary meeting room (control group).

The results showed that participants who took their break in the regeneration pod reported lower post-break anxiety and perceived task-load, and higher post-break arithmetic task performance, than the control group.

The findings suggest that purpose-built spaces for restoration within office buildings will be effective for helping employees to proactively manage their stress levels while at work. Biophilic design principles will enhance the effectiveness of these spaces, and this does not necessarily need to involve direct exposure to plants or views of nature.

To the best of the authors’ knowledge, this is the first randomised field experiment to test the effectiveness of a purpose-built space for restoration within offices. Additionally, this paper explores different forms of biophilic design than previous studies.

Advancements in wireless sensor technology and building modelling techniques have enabled facilities managers to understand the environmental performance of the workplace in more depth than ever before. However, it is unclear to what extent this data can be used to predict subjective environmental comfort. This study aims to pilot test a methodological framework for integrating real-time environmental data with subjective ratings of environmental comfort.

An open-plan office was fitted with environmental sensors to measure key indoor environmental quality parameters (carbon dioxide, temperature, humidity, illumination and sound pressure level). Additionally, building modelling techniques were used to calculate two spatial metrics (“workspace integration” and workspace density) for each workspace within the study area. In total, 15 employees were repeatedly sampled across an 11-day study period, providing 78 momentary assessments of environmental comfort. Multilevel models were used to explore the extent to which the objective environmental data predicted subjective environmental comfort.

Higher carbon dioxide levels were associated with more negative ratings of air quality, higher “workspace integration” was associated with higher levels of distractions, and higher workspace density was associated with lower levels of social interactions.

To our knowledge, this is the first field study to directly explore the relationship between physical environment data collected using wireless sensors and subjective ratings of environmental comfort. The study provides proof-of-concept for a methodological framework for the integration of building analytics and human analytics.

The purpose of this study is to pilot test the effectiveness of the experience sampling approach for measuring employee satisfaction with the workplace environment. Additionally, the authors also aimed to explore, which aspects of environmental comfort have the strongest impact on momentary well-being and productivity.

In total, 15 knowledge workers in an open-plan office environment were sent a brief survey (measuring environmental comfort, momentary well-being and perceived productivity) each day over an 11-day study period and provided 78 individual survey responses in total.

All but one of the measures on the survey had low test-retest reliability, indicating that employees’ experiences of environmental comfort varied significantly each time they completed the survey. Additionally, higher environmental comfort was associated with improved well-being and productivity.

The results suggest that an experience sampling approach to the workplace occupant survey is justified to better capture the temporal variability in experiences of environmental comfort. The results also suggest that improving environmental comfort, particularly by reducing the level of distractions, will enable employees to work more productively.

To the best of the authors’ knowledge, this is the first field study which has attempted to directly address limitations in traditional occupant surveys by using an experience sampling approach rather than a one-time-only questionnaire.

The purpose of this paper is to identify and discuss opportunities for health promotion through the workplace environment, adopting a “salutogenic” perspective of health which more explicitly focuses on factors that support human health and well-being, as opposed to factors which cause disease.

In the introduction, the salutogenic model of health and the Environmental Demands-Resources model are discussed, providing a conceptual framework to represent the workplace environment as a composite of pathogenic “demands” and salutogenic “resources”. Subsequently, a narrative review is performed to discuss the existing literature from the perspective of this novel framework, identifying environmental resources which might strengthen the three components of an employee’s “sense of coherence” (comprehensibility, manageability and meaningfulness), an individual orientation associated with more positive health outcomes.

Comprehensibility can be supported by effectively implementing a clear set of rules governing the use of the workplace. Manageability can be supported through biophilic design solutions, and through design which supports social cohesion and physical activity. Meaningfulness can be supported by recognising the importance of personal identity expression and through design which reinforces the employees’ sense of purpose.

The salutogenic perspective is a potentially valuable but relatively under-considered paradigm in workplace practice. The key contribution of this paper is to encourage researchers and practitioners to recognise the crucial role that an individual’s sense of coherence plays in supporting higher levels of physical and mental health, so that they increase their ability to provide truly “healthy” workplaces, capable of promoting health as well as minimising the risk of disease.

This paper aims to identify the employee characteristics which are most strongly associated with perceived requirements for different aspects of the workplace environment.

A questionnaire was completed by 364 employees from a large private-sector organisation. Respondents were surveyed on different work-related, personality and demographic characteristics. They then completed a series of items measuring perceived requirements for four aspects of the workplace environment (workspace segregation, workspace territoriality, individual environmental control and aesthetic quality). Associations between employee characteristics and perceived workplace requirements were explored using multiple regression analyses.

Numerous significant associations emerged. For example, the requirement for more segregated workspaces was associated with higher susceptibility to distraction, and the requirement for higher workspace territoriality was associated with less positive perceptions regarding the impact of flexible working on work effectiveness.

The individual difference factors which moderate satisfaction with the workplace environment have received relatively little attention in past research. The present study addresses this knowledge gap by including a wider range of employee characteristics and comprehensively investigating which of these most strongly predict differences in perceived requirements for the workplace.

The purpose of this paper is to explore the extent to which Job Demands-Resources (JD-R) theory (Demerouti et al., 2001; Bakker and Demerouti, 2017) is an appropriate conceptual framework for understanding the physical environment for work.

A conceptual analysis of the multidisciplinary workplace literature was performed to assess the core propositions of JD-R theory as they relate to the workplace environment.

The analysis confirms that the workplace environment can be viewed as a composite of environmental demands (which instigate a health impairment process) and environmental resources (which trigger an engagement process). Employees proactively try to improve the suitability of their workspace through environmental crafting, motivated by minimising demands and maximising resources.

The application of JD-R theory to the workplace environment fills a gap in the literature for a framework which captures the dynamic nature of the employee-workplace relationship.

In spite of escalating efforts to curb abuse, fraud, and corruption in Congress, members of Congress persist in violating the norms, rules, and laws that aim to ensure they behave ethically. This chapter combines qualitative and quantitative analysis to describe congressional corruption in the modern era. Case studies illustrate consequential financial scandals while also differentiating four categories of corrupt financial practices.

Existing datasets on congressional scandals span the time period from 1972 to 2010, and this chapter extends the dataset to 2018. The analysis next uses the dataset to answer important questions empirically. Which types of scandals occur more often? Have these scandals grown more common or less common over time? What are the consequences of financial scandals for representatives' careers as public servants?

This paper examines the exercise of Black employee voice in South Africa over the past 53 years. Black workers constitute almost 4 out of every 5 workers in the country and experienced racial oppression from the time of colonisation up to the end of apartheid in 1994. They are still congregated around the lower skilled occupations with low incomes and high unemployment levels.

The paper draws on the theory of voice, exit and loyalty of Albert Hirschman, but extends voice to include sabotage as this encapsulates the nature of employee voice from about 2007 onwards. It reflects a culture of insurgence that entered employment relations from about that time onwards, but was lurking below the surface well before then.

The exercise of employee voice has gone through five phases from 1963 to mid-2016 starting with a silent phase for the first ten years when it was hardly heard at all. However, as a Black trade union movement emerged after extensive strikes in Durban in 1973, employee voice grew stronger and stronger until it reached an insurgent phase.

The phases employee voice went through were heavily influenced by the socio-political situation in the country. The reason for the emergence of an insurgent phase was due to the failure of the ruling African National Congress government to deliver services and to alleviate the plight of the poor in South Africa, most of whom are Black. The failure was due to neo-patrimonialism and corruption practised by the ruling elite and politically connected. Protests by local communities escalated and became increasingly violent. This spilled over into the workplace. As a result many strikes turned violent and destructive, demonstrating voice exercised as sabotage and reflecting a culture of insurgence.

This paper aims to create a terminal area operations (TAO) analysis software that can accurately appreciate the nuances of hybrid electric distributed propulsion (HEDP), including unique failure modes and powered-lift effects.

The program was written in Visual Basic with a user interface in Microsoft Excel. It integrates newly defined force components over time using a fourth order Runge-Kutta scheme.

Powered-lift, HEDP failure modes and electrical component thermal limitations play significant roles on the performance of aircraft during TAO. Thoughtful design may yield better efficiency; however, care must be given to address negative implications. Reliability and performance can be improved during component failure scenarios.

This program has and will support the investigation of novel propulsion system architectures and aero-propulsive relationships through accurate TAO performance prediction.

Powered-lift and HEDP architectures can be employed to improve takeoff and climb performance, both during nominal and component failure scenarios, however, reliance on powered-lift may result in faster approach speeds. High-lift and system failure behavior may also allow new approaches to design and sizing requirements.

This program is unique in both the public and private sectors in its broad capabilities for TAO analysis of aircraft with HEDP systems and powered-lift.
