Nonperturbative Infrared Finiteness in a Superrenormalizable Scalar Quantum Field Theory.

We present a study of the IR behavior of a three-dimensional superrenormalizable quantum field theory consisting of a scalar field in the adjoint of SU(N) with a φ^{4} interaction. A bare mass is required for the theory to be massless at the quantum level. In perturbation theory, the critical mass is ambiguous due to IR divergences, and we indeed find that at two loops in lattice perturbation theory the critical mass diverges logarithmically.

A Phenomenological Study of the Work Environment in Long-Term Care Facilities for the Older Adults.

Attempts to meet the increasing demand for long-term care (LTC) services have been hindered by acute staff shortages and high turnover. Distinct from previous studies, a descriptive phenomenological approach with van Kaam's controlled explication method was adopted in this study, to delineate how attributes of the LTC work environment shape the workforce crisis. Individual interviews were conducted with 40 LTC workers from 10 facilities in Hong Kong.

Evaluation of the user seal check on gross leakage detection of 3 different designs of N95 filtering facepiece respirators.

Background: The use of N95 respirators prevents spread of respiratory infectious agents, but leakage hampers its protection. Manufacturers recommend a user seal check to identify on-site gross leakage. However, no empirical evidence is provided.

Using the Roy adaptation model to develop an antenatal assessment instrument.

The utility of a nursing model as a framework to understand and explain a health phenomenon is fundamental to guide nursing practice. In this article, the authors aim to provide an examination of the Roy adaptation model as a basis for the development of an instrument used for assessing the health needs of pregnant women. With the congruence between the concepts in the Roy adaptation model and antenatal practice, an antenatal assessment instrument is developed.

Job stress, coping and health perceptions of Hong Kong primary care nurses.

Few empirical studies have investigated job stress, coping and health perceptions of nurses working in primary care settings. One thousand self-report questionnaires, which consisted of the modified Nursing Stress Scale, Coping with Work Stress Checklist and Health Perceptions Questionnaire, were distributed randomly to a group of Hong Kong nurses working in primary care settings, to examine issues related to job stress. Three hundred and sixty-two nurses responded.
