Encryption for the masses? An analysis of PGP key usage

Despite the rise of alternatives, email remains integral to technology-mediated communication. To protect email privacy the encryption software Pretty Good Privacy (PGP) has been considered the first choice for individuals since 1991. However, there is little scholarly insight into the characteristics and motivations for the people using PGP. We seek to shed light on social aspects of PGP: who is using PGP for encrypted email communication, how and why? By understanding those using the technology, questions on the motivations, usability, and the political dimension of communication encryption can be contextualized and cautiously generalized to provide input for the design of privacy-enhancing technologies. We have greatly extended the scale and scope of existing research by conducting a PGP key analysis on 4.27 million PGP public keys complemented by a survey filled out by former and current PGP users (N = 3,727). We show that a relatively small homogeneous population of mainly western, technically skilled, and moderately politically active males is using PGP for privacy self-management. Additionally, findings from existing research identifying poor usability and a lack of understanding of the underlying mechanisms of PGP can be confirmed

Measuring the work environment among healthcare professionals:Validation of the Dutch version of the Culture of Care Barometer

Objectives A positive work environment (WE) is paramount for healthcare employees to provide good quality care. To stimulate a positive work environment, employees’ perceptions of the work environment need to be assessed. This study aimed to assess the reliability and validity of the Dutch version of the Culture of Care Barometer (CoCB-NL) survey in hospitals. Methods This longitudinal validation study explored content validity, structural validity, internal consistency, hypothesis testing for construct validity, and responsiveness. The study was conducted at seven departments in two Dutch university hospitals. The departments were included based on their managers’ motivation to better understand their employees’ perception of their WE. All employees of participating departments were invited to complete the survey (n = 1,730). Results The response rate was 63.2%. The content of the CoCB-NL was considered relevant and accessible by the respondents. Two factor models were found. First, confirmative factor analysis of the original four-factor structure showed an acceptable fit (X2 2006.49; df 399; p = &lt;0.001; comparative fit index [CFI] 0.82; Tucker-Lewis index [TLI] 0.80; root mean square error of approximation [RMSEA] 0.09). Second, explanatory factor analysis revealed a five-factor model including ‘organizational support’, ‘leadership’, ‘collegiality and teamwork’, ‘relationship with manager’, and ‘employee influence and development’. This model was confirmed and showed a better fit (X2 1552.93; df 395; p = &lt; 0.00; CFI 0.87; TLI 0.86; RMSEA 0.07). Twelve out of eighteen hypotheses were confirmed. Responsiveness was assumed between the measurements. Conclusions The CoCB-NL is a valid and reliable instrument for identifying areas needing improvement in the WE. Furthermore, the CoCB-NL appears to be responsive and therefore useful for longitudinal evaluations of healthcare employees’ work environments.</p

Cross-disciplinary lessons for the future internet

There are many societal concerns that emerge as a consequence of Future Internet (FI) research and development. A survey identified six key social and economic issues deemed most relevant to European FI projects. During a SESERV-organized workshop, experts in Future Internet technology engaged with social scientists (including economists), policy experts and other stakeholders in analyzing the socio-economic barriers and challenges that affect the Future Internet, and conversely, how the Future Internet will affect society, government, and business. The workshop aimed to bridge the gap between those who study and those who build the Internet. This chapter describes the socio-economic barriers seen by the community itself related to the Future Internet and suggests their resolution, as well as investigating how relevant the EU Digital Agenda is to Future Internet technologists

Workplace 4.0: exploring the implications of technology adoption in digital manufacturing on a sustainable workforce

As part of the Industry 4.0 movement, the introduction of digital manufacturing technologies (DMTs) poses various concerns, particularly the impact of technology adoption on the workforce. In consideration of adoption challenges and implications, various studies explore the topic from the perspective of safety, socio-economic impact, technical readiness, and risk assessment. This paper presents mixed methods research to explore the challenges and acceptance factors of the adoption of human-robot collaboration (HRC) applications and other digital manufacturing technologies from the perspective of different stakeholders: from manufacturing employees at all levels to legal experts to consultants to ethicists. We found that some of the prominent challenges and tensions inherent in technology adoption are job displacement, employee’s acceptance, trust, and privacy. This paper argues that it is crucial to understand the wider human factors implications to better strategize technology adoption; therefore, it recommends interventions targeted at individual employees and at the organisational level. This paper contributes to the roadmap of responsible DMT and HRC implementation to encourage a sustainable workforce in digital manufacturing.Engineering and Physical Sciences Research Council (EPSRC): EP/L015463/1 and EP/R032718/1

Defining a positive work environment for hospital healthcare professionals: A Delphi study

Introduction: The work environment of healthcare professionals is important for good patient care and is receiving increasing attention in scientific research. A clear and unambiguous understanding of a positive work environment, as perceived by healthcare professionals, is crucial for gaining systematic objective insights into the work environment. The aim of this study was to gain consensu

A head mounted augmented reality design practice for maintenance assembly: toward meeting perceptual and cognitive needs of AR users

Head Mounted Display (HMD) based Augmented Reality (AR) is being increasingly used in manufacturing and maintenance. However, limited research has been done to understand user interaction with AR interfaces, which may lead to poor usability, risk of occupational hazards, and low acceptance of AR systems. This paper uses a theoretically-driven approach to interaction design to investigate the impact of different AR modalities in terms of information mode (i.e. video vs. 3D animation) and interaction modality (i.e. hand-gesture vs. voice command) on user performance, workload, eye gaze behaviours, and usability during a maintenance assembly task. The results show that different information modes have distinct impacts compared to paper-based maintenance, in particular, 3D animation led to a 14% improvement over the video instructions in task completion time. Moreover, insights from eye gaze behaviours such as number of fixations and transition between Areas of Interest (AOIs) revealed the differences in attention switching and task comprehension difficulty with the choice of AR modalities. While, subjective user perceptions highlight some ergonomic issues such as misguidance and overreliance, which must be considered and addressed from the joint cognitive systems’ (JCSs) perspective and in line with the predictions derived from the Multiple Resources Model
