基于层次分析法的信息系统安全评价研究

利用层次分析法(AHP)的原理与方法,提出了信息系统安全评价指标体系,建立综合分析评价模型,采用向量范数法对判断矩阵进行优化。描述了信息系统安全评价的方法和流程,计算出评价指标的综合权重。通过实例说明这一模型能对信息系统安全等级进行综合评价。     

Effects of Consumer Weight Level and Advertising Appeals on Consumer Attitude Toward Food and Advertisements

This study examines the link between consumer weight level, food type, and consumer attitude toward both food and food advertisements. Further, this research explores how food advertisements containing emotional or informational claims influence the attitudes of overweight and normal-weight consumers. Two experiments were conducted to study the interaction between weight levels, food types (meat vs. vegetables), and advertising appeals (emotional vs. informational). The results showed mixed support for the six hypotheses. The findings indicate that consumer weight level interacts with food types, and emotional/information appeals affecting food evaluation and attitudes toward food advertisements. Managerial implications for food manufacturers and advertisers are discussed.     

一种考虑稳定性的动态综合评价新模型

针对动态综合评价需要考虑被评对象的稳定性问题,提出了一种综合考虑指标权重、时间权 重和稳定性的动态综合评价模型。定义了稳定因子来表征被评对象指标的稳定程度,采用离 差最大化的方法确定指标权重,提出了一种基于极小范数时间权重确定方法。将所提模型应 用于军事IP网络评价,结果表明该模型能够把被评对象的稳定性反映到评价结果中。     

天然肠衣搭配的优化模型

首先,采用假设检验法,建立双目标整数规划模型;其次,通过引入权重,将双目标整数规划转换为单目标整数规划;最后利用Lingo软件进行求解,对给定的肠衣原料进行搭配,得到总捆数为191捆,剩余肠衣25根。     

前海深港现代服务业合作区港资银行准入法律问题探讨

金融业是前海合作区重点发展的行业,推进深港金融业的紧密合作,必须创造足够的政策优势空间,吸引更多的港资金融机构在此聚集。内地对港资银行的市场准入要求较高,应参照香港银行业准入标准,通过签订新的CEPA补充协议,并由深圳市行使经济特区立法权,适当放宽在前海设立机构的港资银行的各项准入门槛。     

物流区域合作政策评价体系研究

我国已相继出台多项物流区域评价政策,但是却缺乏系统化的和较为完善的物流区域合作政策评价体系及评价方法,本文基于层次分析法及模糊数学的定量评估方法,设计出适合于评价物流区域政策的评价体系,并提出合理的评价模型,以期对政府出台相应政策及政策的改进提供可行性的借鉴。     

基于模糊联系度的危化品公路运输安全风险评估

为了有效降低危化品公路运输事故风险,提高危化品运输安全管控能力,构建了含23个动、静态指标的危化品公路运输安全风险评估指标体系,采用组合权重对评估指标赋权;基于集对分析理论,对专家打分分值与组合权重深入分析,引入综合差异度系数的概念,确定模糊联系度,提出一种危化品公路运输安全风险评估方法;以西安某公司至上海的运输任务为例,进行实例应用。结果表明：除危化品因素外,其余一级指标均存在风险上升趋势,其中人员因素风险上升趋势尤其明显,危化品公路运输整体风险状态处于微反势9级,风险较大,与实际情况相符。所提方法可实现危化品公路运输动、静态风险评估,为危化品公路运输风险研究提供参考。     

企业竞争力的一种评价方法

讨论了企业竞争力的一种模糊评价方法,归纳了影响竞争力评价的因素。给出了一种应用于企业竞争力评价的指标体系和模糊评价方法,运用主成分分析法确定各指标的权重,为企业竞争力评价提供了一种定量分析方法。     

Adolescents' body‐tanning behaviours: influences of gender,body mass index,sociocultural attitudes towards appearance and body satisfaction

The goal of this study was to identify and examine the various factors affecting adolescents' body‐tanning behaviours. Gender, body mass index (BMI), sociocultural attitudes towards appearance (SATA) and body satisfaction were examined in order to determine how these variables influence both outdoor sun‐tanning and indoor tanning‐bed use. Self‐administered survey data were collected from 155 adolescent boys and 202 adolescent girls with an average age of 14.3. Multivariate analysis of variance and multiple regression methods were used to analyse the data. Adolescent girls tended to engage in both outdoor and indoor tanning. Overall, adolescents' SATA significantly affected their body‐tanning behaviours. However, BMI and body satisfaction revealed a significant effect only on indoor tanning behaviour. Implications for the design of interventions and overall health promotion towards adolescents are discussed with suggestions for future research.
