We describe a 37-year-old male engineer who presented with cough and dyspnea 3 weeks after exposure to dust resulting from the collapse of the World Trade Center (WTC). Radiographs of the chest and high-resolution CT demonstrated diffuse miliary nodularity. Lung biopsy specimens confirmed the presence of diffuse, noncaseating granulomatous nodules. Scanning electron microscopy and energy-disper...

This action research examines the concept of Willingness to Communicate (WTC) in a second language acquisition context. The researcher investigated the contributors of WTC in a foreign language classroom setting. Therefore, a multiple assignments method and sequence was applied. Participants of this study were students who matriculated in a United States (U.S.) undergraduate program, studying G...

Maritime search and surveillance-type missions typically require heavy human involvement. A set of unmanned aerial vehicles (UAVs) has the potential to provide a “sensor network” to greatly increase efficiency and effectiveness of these surveillance type missions. However, limited autonomy is still a bottleneck to networked UAV applications. High operator involvement is required in logistics an...

Willingness to communicate (WTC) research has recently witnessed a paradigm shift with the more recent studies looking at shifting and dynamic nature of variable. A growing body literature interpreted such dynamicity from complex systems (CDS) perspective. The theory CDS four basic properties, one which, focus this study, is interconnectedness among subsystems. This property mainly involves int...

Abstract: With the global expansion of China's economy, Chinese has established itself as a major language. Since then, higher education students' desire to learn increased dramatically. However, strategies for foreign language learning and anxiety both play key role in ability communicate Chinese. Thus, purpose this study is examine influence (LLS), particularly those associated with different...

This study explores the relationships between L2 motivational self system (L2MSS)—Ideal self, Ought-to and Learning experience—and willingness to communicate (WTC) based on results of a questionnaire survey 120 freshmen from English majors (English, Business English, Translation). The demonstrate that: (1) in L2MSS, ideal has greatest mean 3.83, WTC 3.74. Overall, each value is upper-middle ran...

In writing this paper, I call for a serious investigation of the hypothesis that WTC 7 and the Twin Towers were brought down, not just by damage and fires, but through the use of pre-positioned explosives. I consider the official FEMA, NIST, and 9-11 Commission reports that fires plus damage alone caused complete collapses of all three buildings. And I present evidence for the explosive-demolit...

This study examines a group of Saudi military cadets studying English as foreign language and their willingness to communicate (WTC) using English. The investigated the relationship between cadets’ WTC vocabulary size, along with perceived competence. In addition, looked at L2 anxiety. A survey was designed for administered 113 an average age 20 years old. Correlation regression analyses reveal...
