要旨

Background:

This study examined the longitudinal influence of psychosocial safety climate (PSC) on self-endangering work behavior (SEWB), considering working time flexibility (fixed vs. flextime arrangement).

Methods:

A two-wave web-based longitudinal survey was conducted in Japan in November 2021 and May 2022. Responses from 826 full-time workers were analyzed. Fixed-effects model analyses were used to examine the within-person effect of PSC on SEWB and test the moderation effect of working time flexibility.

Results:

The decrease in PSC was significantly associated with the increase in SEWB under the flextime arrangement, but not under the fixed-time arrangement, presenting the significant moderation effect of working time flexibility.

Conclusions:

The findings highlight the heightened vulnerability of flextime workers to SEWB in a deterioration of PSC, emphasizing the need for organizations to maintain a healthy organizational climate when implementing flextime.

Factors Affecting Workability

Factors Affecting Workability

The workability of concrete is a critical characteristic that influences the ease of mixing, handling, and finishing the concrete. It is affected by several factors including water content, aggregate properties, and admixtures like air entrainment. Water plays a fundamental role as it lubricates the concrete mix, facilitating easier movement and placement. However, the water requirement varies depending on the texture and shape of aggregates. Finer particles and angular, rough-textured...

Strategies of Self-Presentation I: Strategic Self-Presentation

Strategies of Self-Presentation I: Strategic Self-Presentation

Strategic self-presentation refers to individuals' intentional efforts to influence how others perceive them. This process is employed in various social and professional settings, such as job interviews, dating, politics, and legal contexts, where individuals seek to shape impressions to gain social or material advantages. While people generally present themselves in ways that align with their authentic characteristics, external factors, such as cognitive load, can hinder their ability to...

Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Obedience

Obedience

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

Factors Affecting Illness

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Social Traps

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...
