This study examined Omani EFL learners’ perceptions toward their willingness to communicate (WTC) in English. To this end, 204 students majoring in English language at a private university in Oman were assigned a questionnaire adapted from McCroskey’s (1992) WTC scale to determine possible effects of communication and affective variables on their WTC in English. After assessing the normality di...

given the fact that developing an intimate relationship between teacher and students creates a safe learning environment (harran, 2006), and because teacher immediacy is proved to increase students’ motivation for learning (velez & cano, 2008), this study was an attempt to explore the relationship between iranian efl learners’ perceived teacher immediacy and their willingness to communicate...

OBJECTIVE Explore relationships between World Trade Center (WTC) exposures and sarcoidosis. METHODS Sarcoidosis has been reported after exposure to the WTC disaster. We ascertained biopsy-proven post-9/11 sarcoidosis among WTC Health Registry enrollees. Cases diagnosed after Registry enrollment were included in a nested case-control study. Controls were matched to cases on age, sex, race or e...

The attack on the World Trade Center (WTC) created an acute environmental disaster of enormous magnitude. This study characterizes the environmental exposures resulting from destruction of the WTC and assesses their effects on health. Methods include ambient air sampling; analyses of outdoor and indoor settled dust; high-altitude imaging and modeling of the atmospheric plume; inhalation studies...

Pulmonary vascular loss is an early feature of chronic obstructive pulmonary disease. Biomarkers of inflammation and of metabolic syndrome predict loss of lung function in World Trade Center (WTC) lung injury (LI). We investigated if other cardiovascular disease (CVD) biomarkers also predicted WTC-LI. This nested case-cohort study used 801 never-smoker, WTC-exposed firefighters with normal pre-...

Rescue workers and residents exposed to the environment surrounding the collapse of the World Trade Center (WTC) on September 11, 2001, have suffered a disproportionate incidence of chronic lung disease attributed to the inhalation of airborne dust. To date, the pathophysiology of this lung disease is poorly understood. The aim of this study was to examine whether airborne dust contaminants rec...

OBJECTIVE The objective of this research is to determine whether responders and survivors of the World Trade Center (WTC) disaster experience symptoms of neuropathy at a rate higher than those not exposed. METHODS A survey of neuropathic symptoms in patients who were and were not exposed at the WTC based upon the Michigan Neuropathy Screening Instrument (MNSI). RESULTS Even after correction...

Unlike most altimetric missions, CryoSat-2 is not equipped with an onboard microwave radiometer (MWR) to provide wet tropospheric correction (WTC) to radar altimeter measurements, thus, relying on a model-based one provided by the European Center for Medium-range Weather Forecasts (ECMWF). In the ambit of ESA funded project CP4O, an improved WTC for CryoSat-2 data over ocean is under developmen...

PURPOSE The aim is to study the influence of change in work-time control (WTC) on work-home interference (WHI) while adjusting for other work-related factors, demographics, changes at work and WHI at baseline among women and men. An additional aim was to explore sex differences in the relation between change in WTC and WHI. METHODS The study included working participants of the Swedish Longit...

individual’s first language (l1) and second language (l2) communication could be affected by willingness to communicate (wtc) which is considered an influential factor affecting one’s second language development. studying various aspects of wtc has been the home of choice for the researchers in the sla domain (e.g., clement, dornyei, and noels, 1998; mccroskey, & baer, 1985; kang, 2005; macinty...
