Impact of just-in-time on job content, employee attitudes and well-being: a longitudinal study

Article Abstract:

The introduction of just-in-time (JIT) production systems in manufacturing organizations reduces control over work timing and the level of job satisfaction, and increases the production pressure. JIT fails to cause any significant impact on the job content and has no effect on psychological strain or psychological outcomes. JIT system does not change the workers' job but does change the job content as per the predictions of a conceptual framework. JIT improves performance by simplifying the process and technology of production. Implications of the findings are discussed.

The impact of light and color on psychological mood: A cross-cultural study of indoor work environments

Article Abstract:

A study carried out in real work environments at different seasons and in countries with different latitudes examines whether indoor lighting and color would have any systematic impact on the mood of people working indoors. Results suggest that the light and color of the workplace itself does have an influence on the mood of persons working there, although the illuminance as measured in objective terms showed no significant impact on mood at any other time of the year.

Psychological impact of air velocity variations in a ventilated room

Article Abstract:

Two experiments that investigated psychological impact of two velocity conditions, constant low velocity (V1) and variations of low and high velocity (V2) in two temperature conditions, is presented. The result shows that a cooling effect induced by air velocity variations is beneficial for subjects in a ventilated room and that their perceived pleasantness of the indoor climate met at a higher room temperature than otherwise.
