Manipulating the temporal locus and content of mind-wandering

The human brain has a tendency to drift into the realm of internally-generated thoughts that are unbound by space and time. The term mind-wandering (MW) is often used describe such thoughts when they are perceptually decoupled. Evidence suggests that exposure to forward and backward illusory motion skews the temporal orientation of MW thoughts to either the future or past respectively. However, little is known about the impact of this manipulation on other features of MW. Here, using a novel experimental paradigm, we first confirmed that our illusory motion method facilitated the generation of MW thoughts congruent with the direction of motion. We then conducted content analyses which revealed that goal orientation and temporal distance were also significantly affected by the direction of illusory motion. We conclude that illusory motion may be an effective means of assaying MW and could help to elucidate this ubiquitous, and likely critical, component of cognition.     

Events,processes, and the time of a killing

The paper proposes a novel solution to the problem of the time of a killing (ToK), which persistently besets theories of act-individuation. The solution proposed claims to expose a crucial wrong-headed assumption in the debate, according to which ToK is essentially a problem of locating some event that corresponds to the killing. The alternative proposal put forward here turns on recognizing a separate category of dynamic occurrents, viz. processes. The paper does not aim to mount a comprehensive defence of process ontology, relying instead on extant defences. The primary aim is rather to put process ontology to work in diagnosing the current state of play over ToK, and indeed in solving it.     

“Scattered In Times”

Climate change is a temporally fragmented phenomenon: the causes and effects at work are dispersed over a remarkably long time period. Climate change exceeds human ability to forecast and quantify its effects in time. This creates serious epistemic, moral, and psychological difficulties and poses challenges to generating adequate ethical responses. Augustine’s understanding of time as a measure of imagination emphasizes the way in which human beings actively shape their sense of time. He sees “looking forward” in time as a matter of spiritual vocation that collects the self out of dispersion and connects to a transgenerational collective. A notable example of how this “looking forward” may be practiced is singing the Psalms. The Augustinian “temporal imagination” links the imaginative, affective, moral, and vocational dimensions of measuring time. This offers some preliminary avenues for reimagining a sense of time responsive to climate change’s temporal fragmentation.     

TIME, (COM)PASSION,AND ETHICAL SELF-FORMATION IN EVANGELICAL HUMANITARIANISM

This article examines narratives, images, and stories that give insight to everyday experimentation and ethical self-formation. I use the case of World Vision and its early leaders to unpack genealogies of American evangelical humanitarianism. Rather than seeking to identify American evangelicalism’s normative ethical stance, I aim to expand the discussion in anthropology of ethics on ethical self-formation through examining the tensions, reflections, and processes of becoming among evangelical humanitarians. In doing so, I examine two focal areas of ethical self-formation among early World Vision leaders. The first is oscillation between and mixing of passion and compassion frameworks in the American evangelical imagination. Second, I identify a range of temporal frames that evangelicals draw on to make sense of and formulate ethical responses to human needs encountered abroad.     

A taxonomic foundation for evidence-based research on employee performance management

This study presents a taxonomic foundation for research on employee performance management practices based on a comprehensive review of the literature (198 articles and book chapters). The taxonomy consists of 50 practices organized within seven topic categories, including an evaluation of the amount of research evidence supporting each practice. This taxonomic foundation facilitates the aggregation, integration, interpretation, and explanation of performance management research based on a role-theoretic perspective derived from the behavioural approach to strategic human resource management. The proposed direct-linkage path model shows how this taxonomic foundation ties performance management practices to behaviours and results. We build on this Practice – Behaviour – Results (PBR) critical path model with moderators and mediators based on cognitive and social factors identified in the extensive previous research. This PBR model provides a foundation for orderly and structured growth for future research that will enhance the connection between research and improved organizational practices in performance management, as well as a guide to best practices in performance management.     

Pedestrians’ road crossing decisions and body parts’ movements

This study aims to examine pedestrians' crossing decision, body parts' movement and full body movement, just before and during road crossing in a simulated setup. To accomplish this, a novel experimental setup for analyzing pedestrians’ crossing behavior and motion was developed where the simulated display was synchronized with a 3D motion capturing system. Twenty participants, divided into control and an experimental time pressure group, observed sixteen short (less than 30 s) and long road (70 s or more) crossing scenarios with varying crossing opportunities. Based on the crossing opportunities they were asked to cross a 3.6 m wide one-lane one way urban road. It was found that the crossing initiation process consists of four incremental movements of body parts: the head and the shoulder first; the hip, wrist and elbow second; the knee as a separate joint, and finally the ankle. Results showed that pedestrians’ decision to cross and body parts movement are influenced by time pressure and wait time for a safe crossing opportunity. Specifically, pedestrians prepare their body parts earlier, initiate their crossing earlier, and adjust their speed to compensate for the risk taken in less safe or non-safe crossing opportunities. Within the control group, women tended to be more risk avoiding than men, however those differences disappeared in the time pressure group. Most importantly, the findings provide initial evidence that this novel simulation configuration can be used to gain precise knowledge of pedestrians’ decision-making and movement processes.     

A medical records managing and securing blockchain based system supported by a Genetic Algorithm and Discrete Wavelet Transform

The privacy of patients is jeopardised when medical records and data are spread or shared beyond the protected cloud of institutions. This is because breaches force them to the brink that they start abstaining from full disclosure of their condition. This type of condition has a negative effect on scientific research, patients and all stakeholders. A blockchain-based data sharing system is proposed to tackle this issue, which employs immutability and autonomy properties of the blockchain to sufficiently resolve challenges associated with access control and handle sensitive data. Our proposed system is supported by a Discrete Wavelet Transform to enhance the overall security, and a Genetic Algorithm technique to optimise the queuing optimization technique as well. Introducing this cryptographic key generator enhances the immunity and system access control, which allows verifying users securely in a fast way. This design allows further accountability since all users involved are already known and the blockchain records a log of their actions. Only when the users’ cryptographic keys and identities are confirmed, the system allows requesting data from the shared queuing requests. The achieved execution time per node, confirmation time per node and robust index for block number of 0.19 s, 0.17 s and 20 respectively that based on system evaluation illustrates that our system is robust, efficient, immune and scalable.
