plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...

heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

A dynamical relationship that connects the extratropical tropopause potential temperature and the nearsurface distribution of equivalent potential temperature was proposed in a previous study and was found to work successfully in capturing the annual cycle of the extratropical tropopause in reanalyses. This study extends the diagnosis of the moisture–tropopause relationship to an ensemble of CM...

This study investigates the amenity value of climate to British households. By using the hedonic price approach, the marginal willingness to pay for small changes in climate variables, specified as averages and ranges, is derived. The estimates suggest that British people would typically prefer a greater distribution of precipitation across the seasons (i.e. holding annual precipitation constan...

Transportation agencies’ motor vehicle count programs tend to be well established and robust with clear guidelines to collect short-term count data, to analyze data, develop annual average daily traffic (AADT) adjustment factors, and to estimate AADT volumes. In contrast, bicycle and pedestrian traffic monitoring is an area of work for most transportation agencies. In most agencies, there are a...

A PC-based utility has been devised for the rapid display and preliminary analysis of long time-series of satellite data such as, for example, the 16-year series of monthly mean global fields of SST measured by the ATSR series of instruments. This utility gives investigators immediate access to the data, which are presented in the form of monthly averages and spatial averaged to half-degree or ...

OBJECTIVE to determine the cost of institutional and familial care for patients with chronic kidney disease replacement therapy with continuous ambulatory peritoneal dialysis. METHODS a study of the cost of care for patients with chronic kidney disease treated with continuous ambulatory peritoneal dialysis was undertaken. The sample size (151) was calculated with the formula of the averages f...

Introduction: Nearly half of occupational accidents in Iran occur in construction sites. Therefore, modeling of occupational accidents in these sites is one of the solutions to design safety strategies to reduce occupational accidents in the field of construction. This study was designed and conducted with the aim of modeling the cause-consequence of accidents in construction sites. Material a...
