[Abstract] Inertia relief analysis is regarded as an effective technique for the modeling of unconstrained structural systems. In this paper the principle of inertia relief analysis is first described. Inertia relief capability of commercial finite element packages is discussed. The paper studies the implementation of inertia relief techniques into finite element analysis of a variety of struct...

Purpose – The purpose of this paper is to compare performance measurement in the humanitarian relief chain with performance measurement in the commercial supply chain, develop performance metrics for the humanitarian relief chain, and present a framework that can be used as a basis for a performance measurement system in the relief sector. Design/methodology/approach – The performance measureme...

Logistic regression may be useful when we are trying to model a categorical dependent variable (DV) as a function of one or more independent variables. This paper reviews the case when the DV has more than two levels, either ordered or not, gives and explains SAS R © code for these methods, and illustrates them with examples.

BACKGROUND Achalasia of the cardia is generally considered a rare disease. Because the cause is uncertain, treatment is palliative and directed at relieving distal oesophageal obstruction. In developed countries, several treatment options are available, but in developing countries, achalasia is usually treated by open surgical myotomy. We reviewed the outcome of management of achalasia in our p...

Background and aim: Pain is common in older adults, but its relationship with ageing is unclear. The aim was to investigate pain among adults aged 72 years and older by means of a population-based sample followed for a period of nine years. Methods: The Swedish National study on Aging and Care (SNAC) is conducted at four research centres. At SNAC-Blekinge (B), 609 (60.6%) women and 396 (39.4%) ...

AIM To identify unique clusters of patients based on their concerns in using analgesia for cancer pain and predictors of the cluster membership. METHODS This was a 3-mo prospective observational study (n = 207). Patients were included if they were adults (≥ 18 years), diagnosed with solid tumors or multiple myelomas, and had at least one prescription of around-the-clock pain medication for ca...
