Effects of Mobile Computer Terminal Configuration and Level of Driving Control on Police Officers’ Performance and Workload

Objective The objective of this study was to assess police officers’ performance and workload in using two mobile computer terminal (MCT) configurations under operational and tactical driving conditions. Background Crash reports have identified in-vehicle distraction to be a major cause of law enforcement vehicle crashes. The MCT has been found to be the most frequently used in-vehicle technology and the main source of police in-vehicle distraction. Method Twenty police officers participated in a driving simulator-based assessment of driving behavior, task completion time, and perceived workload with two MCT configurations under operational and tactical levels of driving. Results The findings revealed that using the MCT configuration with speech-based data entry and head-up display location while driving improved driving performance, decreased task completion time, and reduced police officers’ workload as compared to the current MCT configuration used by police departments. Officers had better driving but worse secondary task performance under the operational driving as compared to the tactical driving condition. Conclusion This study provided an empirical support for use of an enhanced MCT configuration in police vehicles to improve police officers’ safety and performance. In addition, the findings emphasize the need for more training to improve officers’ tactical driving skills and multitasking behavior. Application The findings provide guidelines for vehicle manufacturers, MCT developers, and police agencies to improve the design and implementation of MCTs in police vehicles considering input modality and display eccentricity, which are expected to increase officer and civilian safety.

Data, Detection, and the Redistribution of the Sensible in International Law

One dusty day in 2002, at Takhta Baig Voluntary Repatriation Centre near Peshawar in northwestern Pakistan, an Afghan woman—let us call her Amena—entered a nondescript room and sat down in front of a camera. A brief conversation took place with a woman sitting nearby at a computer terminal. Amena placed her chin where she was directed to do so, swept back a few strands of hair creeping out of her veil, and stared straight ahead for a few seconds while a series of photographs of one of her eyes was taken. Almost immediately, a small alarm sounded on the computer terminal of the woman seated alongside her. Amena was gently ushered toward the other side of the room for discussions with other officials. Some short time later, she was advised that her request to the Office of the United Nations High Commissioner for Refugees (UNHCR) for a modest cash grant and some supplies to aid her and her family's repatriation to Afghanistan had been denied. This was because, according to output of the UNHCR’s iris verification program, she had already received assistance earlier the same year. When asked, Amena admitted that she had indeed sought UNHCR repatriation assistance multiple times, under pressure from family members. She walked away. Soon, she could soon no longer be seen amid the press of trucks, cars, bicycles, and people that stretched to the suburbs in the distance.

Study on Real-Time Monitoring System of Mining Subsidence Area Based on LabVIEW

Taking the mining subsidence as research object, a real-time monitoring scheme was designed. On this basis, a virtual instrument monitoring system based on LabVIEW was constructed. The data acquisition instrument collect real-time data through monitoring of subsidence and subsidence slope deformation by this system in range of mining influence, then control and transform it. After this, the data was transmitted to the computer terminal through wireless transmission equipment, and monitoring will be got after analysis and prediction by computer terminal. This result can provide mining of this area with real-time advice and guidance, to reduce the harms brought by mining subsidence and unnecessary economic losses.

Construction and Research of Virtual Network User File System Based on Upnp and FUSE on Linux

The Development of the computer has been from a single machine to the server, and then server clustering technology, and the emerging "cloud" network, which invariably show the network's role in the computer. Meanwhile, more and more high-end hardware trash or the users may be unbearable of high cost of servers, so the use of existing resources and integration of resources has become increasingly important. This paper will detail a virtual network file system, which based on Upnp (Universal Plug and Play) and FUSE (File system in Usese Space) in Linux operating system. In this study, users can share a computer terminal to collect and use that particular computer terminal on the network to all the resources users are interested in, provided that the shared computer terminals must be installed on a specific Upnp device. In this study, we have successfully implemented single-device-side and single-device-side multithread communication under the Linux or windows operating system.
