Identifying Changing Aviation Threat Environments Within an Adaptive Homeland Security Advisory System

A critical component of aviation security consists of screening passengers and baggage to protect airports and aircraft from terrorist threats. Advancements in screening device technology have increased the ability to detect these threats; however, specifying the operational configurations of these devices in response to changes in the threat environment can become difficult. This article proposes to use Fisher information as a statistical measure for detecting changes in the threat environment. The perceived risk of passengers, according to prescreening information and behavior analysis, is analyzed as the passengers sequentially enter the security checkpoint. The alarm responses from the devices used to detect threats are also analyzed to monitor significant changes in the frequency of threat items uncovered. The key results are that this information‐based measure can be used within the Homeland Security Advisory System to indicate changes in threat conditions in real time, and provide the flexibility of security screening detection devices to responsively and automatically adapt operational configurations to these changing threat conditions.     

利益分析视角下的公路班线客运集约化发展研究

公路班线客运集约化改革的难点在于利益关系的协调。在广泛调研和深入访谈的基础上，结合班线客运发展历程及现状，从利益分析的视角剖析了政府、企业、个体之间的利益诉求、利益冲突及利益博弈的内在机理，指出挂靠关系下企业与个体之间的利益争夺是集约化发展难以推进的根源。研究提出以当前利益分配格局为均衡点的“实收配股”集约化发展改革方案，同时强调政府应转变职能定位、完善相关政策，防止形成市场封锁或垄断。     

Foot-and-Mouth Disease Entrance Assessment Model Through Air Passenger Violations

This article aims to construct a risk model for the prediction of foot-and-mouth disease (FMD) entrance caused by passengers who illegally carry meat products of cloven-hoofed animals through international airports into a country. The risk that meat contaminated with the FMD virus is formulated as the probabilities of FMD factor events (the prevalence of FMD), the commodity factor event (the transportation, storage, and distribution (TSD) factor event), and the passenger event. Data used for analysis were records of illegal meat product carriers from areas A and B intercepted at an international airport in Taiwan. A risk model was proposed to simulate the probability distributions in disease prevalence, probability of FMD virus existing in the meat products after meat processing, and estimation of survival of virus and time period for TSD. The probability of the passenger event was hypothesized with the odds of intercepted passengers and estimated via logistic regression. The results showed that the odds of passengers being intercepted by beagles were higher than those intercepted by Customs. By conducting Monte Carlo simulations, the probability of FMD virus risk caused by FMD factors from area A was 149 times lower than that from area B. The probability of FMD virus risk caused by the passenger event from area A was four times lower than the corresponding probability from area B. The model provides a contribution to FMD prevention and can be a reference for developing models of other diseases.

对春运“民工流”人口迁移的探讨

春运“民工流”是当代中国社会结构变迁的产物。作为春运主体，民工流的出现是社会经济发展的必然结果，同时也是传统文化对人们行为选择影响的表现。民工流的迁移变化既是经济状况的反应。又深刻影响地区经济的发展。一年一度的春运带来多种社会问题。春运问题的核心并非“人多”。而是“集中”。因此对春运难题的解决不能单纯地依靠运力的增加，而要通过深刻挖掘分析春运民工流背后的社会经济文化因素进行综合治理。
