Indubitably, the efficacy of metalinguistic awareness in improving EFL learners’ grammatical knowledge and writing quality has long been an area of great interest in applied linguistics Brown (2001). Accordingly, the main objective of the present study was to investigate the impact of planned and unplanned focus on form instruction on students’ ability to learn grammar and use it appropriately ...

I propose a framework in which consumers have biased beliefs about their future purchase probabilities, leading them to make unplanned purchases. Using this framework, I examine the phenomenon of below-cost pricing and the welfare effects of banning it. When the market is covered, a ban on below-cost pricing raises social surplus, although consumers need not gain—they are only guaranteed to ben...

BACKGROUND Race and sex disparities in in-hospital treatment and outcomes of patients with acute myocardial infarction (MI) have been described, but little is known about race and sex differences in post-MI angina and long-term risk of unplanned rehospitalization. We examined race and sex differences in post-MI angina frequency and 1-year unplanned rehospitalization to identify factors associat...

BACKGROUND A single home-based intervention (HBI) applied immediately after hospital discharge in a cohort of "high-risk" patients with congestive heart failure has been shown to decrease numbers of unplanned readmissions plus out-of-hospital deaths during a period of 6 months. The duration of this beneficial effect remains uncertain. METHODS Hospitalized patients with congestive heart failur...

BACKGROUND Hospitalisation for heart failure is common and post-discharge outcomes, including readmission and mortality, are often poor and are poorly understood. The purpose of this study was to examine patient- and hospital-level variation in the risk of 30-day unplanned readmission and mortality following discharge from hospital with a diagnosis of heart failure. METHODS Prospective cohort...

INTRODUCTION: Unplanned reoperation, specifically for free flap compromise, following head and neck reconstruction can exert a significant toll on the healthcare system and its resources. The timing of the different indications for reoperation remains to be elucidated. Given that the National Surgical Quality Improvement Program (NSQIP) groups all causes of unplanned reoperations into a single ...

BACKGROUND Globally the older population is increasing rapidly. As a result there is an increase in frail older persons living within the community, with increased risks of a hospital admission and higher mortality and morbidity rates. Due to complexity of care, health care professionals face challenges in providing effective case management and avoiding unplanned admissions to hospital. A comm...

Background The majority of medical patients are admitted unplanned and increasingly more patients are admitted to medical departments. But are these admissions all relevant? The Appropriateness Evaluation Protocol (AEP) is an international renowned scoring system that can be used as a marker for the relevancy of unplanned admissions. Our aim was to clarify how large a proportion of the acutely ...

Wireless mesh networks based on IEEE 802.11 technology are a scalable and efficient solution for next generation wireless networking to provide wide-area wideband internet access to a significant number of users. The deployment of these wireless mesh networks may be within different authorities and without any planning, they are potentially overlapped partially or completely in the same service...
