要旨

Objectives:

This study investigates the association between sleep and precarious working conditions in the digital platform economy. Specifically, we examine how six dimensions of employment precariousness are associated with the likelihood of experiencing sleep problems among online platform workers (OPW).

Methods:

We analyze survey data from German-speaking OPW (N = 1969). Sleep outcomes are measured using the Jenkins Sleep Scale (JSS-4), and precariousness is captured by six factor scores derived from an exploratory factor analysis, based on adapted questionnaire items from the Employment Precariousness Scale (EPRES). Logistic regression models with average marginal effects are used to estimate associations, controlling for sociodemographic and work-related characteristics.

Results:

Among the six dimensions of precariousness, two are robustly associated with higher likelihood of reporting sleep problems: Time poverty (the inability to take breaks and leave when needed) and vulnerability (reflecting opaque rating and payment systems). A typical variation across each of these scales corresponds to a 7.7%-8.1% increase in the probability of reporting elevated sleep problems.

Conclusions:

Our findings highlight that platform-related working conditions, particularly opaque management systems and limited ability to take time off, are important correlates of sleep problems among OPW. Addressing these factors may contribute to improving sleep health in this growing segment of the workforce.

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

The Evidence for Evolution

The Evidence for Evolution

Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Introduction to Surveying, Plane Surveying and Geodetic Surveys

Introduction to Surveying, Plane Surveying and Geodetic Surveys

Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Insufficient Sleep and Sleep Deprivation

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Errors and Mistakes in Surveying

Errors and Mistakes in Surveying

Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...

Types of Surveys

Types of Surveys

Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...
