BACKGROUND Unregulated health care aides provide the majority of direct health care to residents in long term care homes. Lower job satisfaction as reported by care aides is associated with increased turnover of staff. Turnover leads to inferior job performance and negatively impacts quality of care for residents. This study aimed to determine the individual and organizational variables associa...

The Safe Home Care Project investigated both qualitatively and quantitatively a range of occupational safety and health hazards, as well as injury and illness prevention practices, among home care aides in Massachusetts. This article reports on a hazard identified by aides during the study's initial focus groups: smoking by home care clients on long-term oxygen therapy. Following the qualitativ...

The effect of Earth albedo variation on the pointing and tracking subsystem of a planetaly optical communication package is analyzed. By studying the Cramer-Rao bound of the tracking error variance, it is shown that, when the Earth albedo is precisely known, the variance in spatial tracking error is inversely proportional to the total signal count. In contrast, a small uncertainty in the Earth ...

Within the general framework of active imaging we address the degree of polarization (DOP) estimation in the presence of additive Gaussian detector noise. We first study the performance of standard DOP estimators and propose a method to increase estimation precision using physically relevant a priori information. We then consider the realistic case of nonuniform illumination distribution. We de...

The long-term care industry in the United States faces serious recruitment and retention problems among nurse aides. At the same time, these low-wage workers may feel trapped in poorly-paid jobs from which they would do well to leave. Despite this tension, not enough is known about how workers fare when they leave (or stay in) such care work. Using longitudinal data from the Survey of Income an...

One of home care's most important resources is the home health aide. Home care nurses play a critical role in preventing abuse of home health aides and identifying violence-prone environments. A prevention strategy that nurses can use to identify and prevent abuse of both patients and aides is presented using an Assessment, Communication, Education, and Supervision model.

AI-Driven Development Environments (AIDEs) Integrate the power of modern AI into IDEs like Visual Studio Code and JetBrains IntelliJ. By leveraging massive language models plethora openly available source code, AIDEs promise to automate many obvious, routine tasks in programming. At same time, come with new challenges think about, such as bias, legal compliance, security vulnerabilities, their ...

Optimal performance of delay tracking loops in a binary linearly-modulated system is investigated, which is compared with the Cramer-Rao lower bound and the performance of a tracking loop suggested by the maximumlikelihood timing estimation.
