Summary
Implementing shift work in southeastern U.S. logging operations can increase production. This study found various shift schedules were successfully adopted by logging companies, with safety precautions in place.
Area of Science:
- Forestry
- Occupational Health
- Industrial Operations
Background:
- Shift work is a recent development in the southeastern U.S. forest industry.
- Logging companies are adopting shift work to boost production and reduce costs.
- Potential impacts of shift work on logging crews are not well-documented.
Purpose of the Study:
- To investigate the implementation of shift work in southeastern U.S. logging.
- To gather data on shift scheduling, safety, and production impacts.
Main Methods:
- Semi-structured interviews with logging company owners across seven southeastern states.
- Data collection focused on employee turnover, shift hours, scheduling, safety, and production.
Main Results:
- Various shift schedules were implemented, mostly under 24 hours per day.
- Both permanent and rotating shift schedules were observed.
- Companies implemented additional safety measures for night work, reporting no in-woods accidents.
Conclusions:
- Shift work can be successfully implemented in the southeastern logging industry.
- Diverse work schedules are feasible for logging operations.
- Safety considerations are crucial when implementing night shifts.

01:24Factors 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...
01:15Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

01:26Methods of Documentation II: POMR
The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.
01:28Factors Affecting Creep
In normal-weight aggregate concrete, the hardened cement paste is the primary contributor to creep, whereas the aggregates, being stiffer than the cement paste, are more resilient to stress-induced deformation. The stiffness of the aggregates is defined by their modulus of elasticity, and the more voluminous they are in the concrete, the less it will creep.
Further, the water/cement ratio is critical, as a lower ratio increases concrete strength, thus reducing creep. The strength of the...

01:28Survey Safety
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...
