Working While the World Sleeps: A Consideration of Sleep and Shift Work Design

The evolution of society and economic pressure has provided the impetus for operating on a 24-hr basis in many industries. This has occurred with relatively little attention toward sleep deprivation and related problems facing shift workers and the organizations employing them. This paper first documents the move toward shift work and some sleep problems associated with it. We then describe sleep disorders that impact job performance. Next, we describe alternative schedules and give suggestions for shift work implementation. Finally, we offer some normative advice regarding the treatment of shift employees.

Light pollution,sleep deprivation,and infant health at birth

We conduct the first study to examine the fetal health impact of light pollution based on a direct measure of skyglow, an important aspect of light pollution. Using an empirical regularity discovered in physics (called Walker's law) as an instrumental variable, we address the potential endogeneity problem associated with the skyglow variable. We find evidence of reduced birth weight, shortened gestational length, and increases in preterm births. Specifically, increased nighttime brightness, characterized by being able to see only one‐fourth to one‐third of the stars that are visible in the natural unpolluted night sky, is associated with an increase of 1.48 percentage points in the likelihood of a preterm birth. Our study adds to the literature on the impact of early‐life exposure to pollution, which so far has focused primarily on air pollution. Our study has important policy implications regarding the necessity of minimizing skyglow that is, for example, contributed by streetlights.

Determining the predictors for ease of sleep while on aircraft: Regression and qualitative analyses

BackgroundFactors predicting passengers’ ability to fall asleep and levels of sleep anxiety, while traveling on a commercial flight, are investigated through a two-study mixed design.MethodsData collected from approximately 400 participants contributed to the development and validation of multiple regression equations and model fit analysis; and participants responded to related open-ended questions.ResultsRegression equations yielded between two to seven predictors and predicted between 6.7% and 27.7% of the variance, ps < .001. Model fit was strong in all cases. An inductive qualitative approach provided detailed insight into passengers’ concerns and barriers over sleeping on a commercial flight.DiscussionAs the field of commercial aviation continues growing, researching and understanding passengers' experiences and perceptions is crucial to the success of the industry as consumers ultimately drive the market. Passengers’ perceptions of sleep quality on commercial aircraft is a key factor influencing their traveling decision. Therefore, a better understanding of this phenomenon can provide crucial information to future passengers, airline companies, regulatory agencies, and manufacturers, potentially influencing the future success of the aviation industry.     

Lagged effect of daily surface acting on subsequent day’s fatigue

The present research investigated the causal relationship between daily surface acting and fatigue at the within-person level. With a longitudinal approach – experience sampling method – based on 10 successive days’ data, this study explored the lagged consequence of service employees’ daily surface acting. The results of multilevel analysis showed that the daily performance of surface acting decreased service employees’ subsequent day’s emotional well-being in the form of increased fatigue. Further, sleep conditions were found to alleviate this detrimental effect. This within-person level investigation of the causal lagged effect of daily surface acting and its moderating contextual factor complements the current emotional labor literature that has overly focused on the between-person level. The theoretical and managerial implications were discussed.
