Problems in interagency collaboration: Lessons from a project that failed

Several institutions (e.g., child welfare, police, court, health, education, social service) are necessarily involved in the management of child abuse in all communities. The need for better cooperation among them has been acknowledged; inquests into child deaths resulting from abuse have often attributed some blame to faulty communication and/or poor cooperation between the institutions. The Community Child Abuse Team (CCAT) Project was designed by these same institutions in Hamilton, Ontario, to maximize interagency collaboration. The hypothesis, that this "interagency collaboration" model would provide more efficient and effective services to abused children and their families, was never tested. During its 30 months of operation the CCAT program never materialized as planned and funding was terminated. This paper describes selected problems and issues that arose during the struggle to implement the project. The central problematic issue was control. Those responsible for the project lacked the power to insist that the design be adhered to during the initial stage.

地表模型上的最短路径算法研究

本文提出了一种基于空间三角网格表示的地表模型上的最短路径算法,该算法利用离散点的空间信息计算得到起点到周围邻接点的最短距离,然后利用逐步向外层边界扩展的方法扩大起点的邻接点范围,直到起点的邻接点中包含终点,此过程可求得s0到t0的最短路径上的关键点,然后求取无原始边连接的两个关键点之间的精确路径点。     

影响中日两国太极拳运动发展的主要因素

采用问卷调查法，对中日两国开展太极拳运动的情况进行分析。运用统计学中的降维方法(K-L变换)，从太极拳运动的目的、效果、要求三方面，找出影响太极拳运动发展的主要因素。即弥补运动不足、受惠于好的设施与教练、培养意志品质；性格开朗、增进食欲、娱乐身心；小规模场所、高水平太极拳俱乐部、体育运动的普及等，并据此提出建议。     

改进的移动商务身份认证方案设计

本文对移动电子商务系统进行了探讨和分析,并针对移动通信的终端设备多以计算能力相对较弱,存储量小的智能卡为主的特点,基于椭圆曲线密码体制,提出了适用于移动电子商务的一种改进的TDAKA(双向认证与密钥协商)协议,同以往方案做了比较,并对该方案的安全性和计算复杂性进行了分析。该协议有以下特点:实现了网络和用户的双向认证;采用数字签名,用户对业务具有不可否认性;由于利用椭圆曲线公开密钥密码算法,使得在同样的安全水平下,可以减小密钥长度,加快计算速度,适应移动通信系统环境。

“Scandalous!”: Reputation,impression management,and employee assistance programs (EAPs) in the NBA

This case study explores how the National Basketball Association (NBA) can rebuild its reputation in response to recurrent player scandals. The case centers on a reputation management firm that has been contracted by the league. The firm has been asked to develop programs that will permit players to make better decisions in their personal lives. NBA commissioner Adam Silver believes such programs will curb the likelihood of future player scandals, thereby enhancing the players’ lives and limiting their ability to damage the league's reputation. To commence the process, the firm has been invited to sit-in on a meeting with Commissioner Silver and a group of NBA staff members who have past work experiences assisting players with their transition to the NBA.This reputation management case study is positioned in two key areas: impression management and employee assistance programs (EAPs). Upon reading the case, answering the provided questions, and completing the activities, students should come to a better understanding as to how to proactively manage corporate reputation. While fictitious names are given, the case study is based on actual interviews with current NBA staff members. The case is ideal for courses pertaining to strategy, policy, organizational behavior, and human resource management. The case could also be useful for sport marketing and sport finance courses if adapted to investigate how the created programs are important for branding and value.     

云计算中电子支付密钥的数据频度隐匿算法

在云计算环境中,研究第三方互联网支付平台的电子支付密钥数据频度隐匿算法,提高密钥的安全性和可靠性。传统的电子支付密钥的数据频度隐匿算法采用威胁树风险评估模型,容易受到病毒攻击导致密钥失效。提出一种基于群签名和椭圆曲线加密的云计算中电子支付密钥的数据频度隐匿算法。构建云计算中电子支付系统总体设计模型,通过交易数据频度、交易数据深度和交易数据索引特性为特征进行云计算融合处理,由此预测出不同时间片内用户的任务提交规律以及用户期望完成时间,通过对混合云的特征压缩处理,得到压缩特征的熵编码结果,结合云计算的虚拟化技术建立一种基于群签名和椭圆曲线加密的电子支付系统密钥数据频度特征分解方案,实现数据频度隐匿算法改进。仿真结果表明,隐匿性和加密性能较好,保证了电子支付密钥的加密可靠性和不可识别性,为用户识别和选择第三方支付工具提供了一定的参考依据。
