工学结合的实践教学改革——改革课程模式合理定位注重内涵发展

为了贯彻教育部[2006]16号文件《关于全面提高高等职业教育教学质量的若干意见》的精神，我们结合国家职业教育体系的特点，从专业设置、教育模式、课程体系和教学内容等方面，大力进行教育教学改革，这体现了社会和职校共同的要求。然而对于职业院校而言，在教育模式的选择上应端正办学指导思想，以培养复合型技术人才为自身首要目标。本文主要从职业院校的课程改革模式以及注重内涵发展两方面提出关于高职院校人才培养的一些构想。     

工业用地年租制供应模式研究

工业用地的出让制过分强化了土地资产属性,使得用地者更多地将其视为投资形式以闲置或低效利用方式加以保有,而并非作为稀缺性生产要素加以高效利用。改革出让制,推行工业用地年租制供应,特别是工业房地产模式下的厂房年租制,有利于打破这种投机性需求膨胀的形成机理,对于提升工业企业竞争力、贯彻落实保护耕地的基本国策具有积极意义。     

旅游管理专业双元制培养模式的应用研究

双元制培养模式代表着旅游高等教育重要的发展方向,双元制培养模式可以采用“双招”模式、订单培养模式、旅游院校自办企业模式和旅游企业实习模式等类型,每种类型都各有利弊,订单式培养模式和旅游企业实习模式是其中应用较为广泛的两种模式,订单式培养模式使旅游高等院校与旅游企业紧密结合,培养方案更多的强调考虑企业的需要,但是经常忽略高等教育自身的规律性和科学性,而实习模式则更多强调考虑如何实现旅游高等院校的培养方案设定的培养目标,但经常会造成培养方案与市场需求的脱节。

On Determining Specifications and Selections of Alternative Technologies for Airport Checked-Baggage Security Screening

Federal law mandates that every checked bag at all commercial airports be screened by explosive detection systems (EDS), explosive trace detection systems (ETD), or alternative technologies. These technologies serve as critical components of airport security systems that strive to reduce security risks at both national and global levels. To improve the operational efficiency and airport security, emerging image-based technologies have been developed, such as dual-energy X-ray (DX), backscatter X-ray (BX), and multiview tomography (MVT). These technologies differ widely in purchasing cost, maintenance cost, operating cost, processing rate, and accuracy. Based on a mathematical framework that takes into account all these factors, this article investigates two critical issues for operating screening devices: setting specifications for continuous security responses by different technologies; and selecting technology or combination of technologies for efficient 100% baggage screening. For continuous security responses, specifications or thresholds are used for classifying threat items from nonthreat items. By investigating the setting of specifications on system security responses, this article assesses the risk and cost effectiveness of various technologies for both single-device and two-device systems. The findings provide the best selection of image-based technologies for both single-device and two-device systems. Our study suggests that two-device systems outperform single-device systems in terms of both cost effectiveness and accuracy. The model can be readily extended to evaluate risk and cost effectiveness of multiple-device systems for airport checked-baggage security screening.     

AbSRiM: An Agent‐Based Security Risk Management Approach for Airport Operations

Security risk management is essential for ensuring effective airport operations. This article introduces AbSRiM, a novel agent‐based modeling and simulation approach to perform security risk management for airport operations that uses formal sociotechnical models that include temporal and spatial aspects. The approach contains four main steps: scope selection, agent‐based model definition, risk assessment, and risk mitigation. The approach is based on traditional security risk management methodologies, but uses agent‐based modeling and Monte Carlo simulation at its core. Agent‐based modeling is used to model threat scenarios, and Monte Carlo simulations are then performed with this model to estimate security risks. The use of the AbSRiM approach is demonstrated with an illustrative case study. This case study includes a threat scenario in which an adversary attacks an airport terminal with an improvised explosive device. The approach provides a promising way to include important elements, such as human aspects and spatiotemporal aspects, in the assessment of risk. More research is still needed to better identify the strengths and weaknesses of the AbSRiM approach in different case studies, but results demonstrate the feasibility of the approach and its potential.     

A Preliminary Investigation of the Reinforcement Function of Signal Detections in Simulated Baggage Screening: Further Support for the Vigilance Reinforcement Hypothesis

The vigilance reinforcement hypothesis (VRH) asserts that errors in signal detection tasks are partially explained by operant reinforcement and extinction processes. VRH predictions were tested with a computerized baggage screening task. Our experiment evaluated the effects of signal schedule (extinction vs. variable interval 6 min) and visual field complexity (dial vs. baggage x-ray) on search behavior rates. There was a main effect for signal schedule [F (1, 20) = 14.0, p = .001, p_rep = 0.99], but no effects for field complexity or interaction. The VRH suggests that performance errors in visual screening work may be reduced through operant conditioning of search behaviors by intensive management of artificially planted signals.     

特殊时期地铁二级分流-联防安检优化模型

恐怖分子经常将安检体系相对薄弱、人流相对密集的地铁站作为攻击的首要目标之一。本文从地铁安检流程优化和跨部门联防协作的角度出发,提出了特殊时期地铁二级分流-联防安检优化模型。结果表明,在特殊时期,通过引入身份证信息库和指纹-人脸识别系统,对乘客进行绿、橙、红三色通道分流安检,能够明显提升普通乘客的社会福利水平;当X光检测系统的准确率越低,被分流到橙色通道乘客比例越大,橙色通道中潜在袭击者比例越高时,社会福利增益越大,暴恐概率越小;在案潜逃人员识别率越高,社会福利增益越大。多部门协防反恐正向反馈越积极,进而可以刺激安防部门优化身份识别系统,直到社会福利增益为零的最优状态。     

A Cost-Benefit Analysis of Alternative Device Configurations for Aviation-Checked Baggage Security Screening

The terrorist attacks of September 11, 2001 have resulted in dramatic changes in aviation security. As of early 2003, an estimated 1,100 explosive detection systems (EDS) and 6,000 explosive trace detection machines (ETD) have been deployed to ensure 100% checked baggage screening at all commercial airports throughout the United States. The prohibitive costs associated with deploying and operating such devices is a serious issue for the Transportation Security Administration. This article evaluates the cost effectiveness of the explosive detection technologies currently deployed to screen checked baggage as well as new technologies that could be used in the future. Both single-device and two-device systems are considered. In particular, the expected annual direct cost of using these devices for 100% checked baggage screening under various scenarios is obtained and the tradeoffs between using single- and two-device strategies are studied. The expected number of successful threats under the different checked baggage screening scenarios with 100% checked baggage screening is also obtained. Lastly, a risk-based screening strategy proposed in the literature is analyzed. The results reported suggest that for the existing security setup, with current device costs and probability parameters, single-device systems are less costly and have fewer expected number of successful threats than two-device systems due to the way the second device affects the alarm or clear decision. The risk-based approach is found to have the potential to significantly improve security. The cost model introduced provides an effective tool for the execution of cost-benefit analyses of alternative device configurations for aviation-checked baggage security screening.     

Agency Problems and Airport Security: Quantitative and Qualitative Evidence on the Impact of Security Training

We analyze the issue of agency costs in aviation security by combining results from a quantitative economic model with a qualitative study based on semi‐structured interviews. Our model extends previous principal‐agent models by combining the traditional fixed and varying monetary responses to physical and cognitive effort with nonmonetary welfare and potentially transferable value of employees' own human capital. To provide empirical evidence for the tradeoffs identified in the quantitative model, we have undertaken an extensive interview process with regulators, airport managers, security personnel, and those tasked with training security personnel from an airport operating in a relatively high‐risk state, Turkey. Our results indicate that the effectiveness of additional training depends on the mix of “transferable skills” and “emotional” buy‐in of the security agents. Principals need to identify on which side of a critical tipping point their agents are to ensure that additional training, with attached expectations of the burden of work, aligns the incentives of employees with the principals' own objectives.

Deceptive Detection Methods for Effective Security with Inadequate Budgets: The Testing Power Index

Detection of contraband depends on countermeasures, some of which involve examining cargo containers and/or their associated documents. Document screening is the least expensive, physical methods, such as gamma ray detection are more expensive, and definitive manual unpacking is most expensive. We cannot apply the full array of methods to all incoming cargoes, for budgetary reasons. We study the problem using principles of game theory, and find that best detection rates are achieved when the available budget is allocated between screening and definitive unpacking using a mixture of strategies that maximize detection rate and, further, serve to deceive opponents as to the specific tests to which contraband will be subjected. This yields increases of as much as 100% in detection, with essentially no increase in inspection cost.
