Survey Safety01:28

Survey Safety

116
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Obedience01:08

Obedience

33.1K
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,...

Barriers to Effective Communication II

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Levels of Communication II: Organizational, Public, and Group Dynamics

2.2K
Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Relationship Formation

41.0K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Area of Science:

  • Occupational Health and Safety
  • Organizational Psychology
  • Construction Management

Background:

  • Frontline construction workers face dual safety communication channels: supervisory (SSC) and coworker (CSC).
  • The distinct impacts and psychological pathways of SSC and CSC on safety behavior are under-researched.
  • Existing literature highlights general safety communication benefits but lacks nuanced understanding of differentiated effects.

Purpose of the Study:

  • To investigate the influence of SSC and CSC on construction workers' safety behavior (SB) using Conservation of Resources (COR) theory.
  • To explore the mediating roles of psychological resources (safety knowledge, self-efficacy, and perceived organizational support) in these relationships.
  • To examine how work pressure (WP) moderates the effects of SSC and CSC on SB.

Main Methods:

  • A quantitative survey was administered to 359 frontline construction workers in China.
  • Data were analyzed using multiple linear regression and moderated interaction analysis (simple slopes).
  • Mediation analysis was employed to test the indirect effects through psychological mechanisms.

Main Results:

  • Both SSC (β = 0.234, p < 0.001) and CSC (β = 0.545, p < 0.001) significantly and positively predict SB.
  • Psychological mechanisms, particularly supervisor motivation (SM) (β = 0.235, p < 0.001), mediate the SSC-SB and CSC-SB links.
  • Work pressure (WP) significantly weakens the positive effect of SSC on SB, but does not affect the CSC-SB relationship.

Conclusions:

  • Findings extend COR theory by elucidating psychological resource pathways in safety communication.
  • CSC demonstrates a more robust positive impact on SB compared to SSC, particularly under high work pressure.
  • Differentiated communication strategies are recommended: leverage CSC consistently and adapt SSC based on work pressure levels to enhance construction site safety.
