大学生人际信任与父母教养方式的相关分析

目的:探讨大学生人际信任与父母教养方式之间的关系,为家庭教育和青少年心理健康提供理论依据。方法:采用父母养育方式评价量表(EMBU)和人际信任量表(ITS)对317名大学生进行调查。结果:是否独子、不同生源地大学生的人际信任水平存在显著差异(P<0.05)。人际信任与父母情感温暖和理解(FF1、MF1)均呈显著的正相关(P<0.01),而与父母惩罚严厉(FF2,MF4)和拒绝否认(FF5,MF3)呈显著的负相关(P<0.05)。结论:家庭教养方式是影响大学生人际信任水平的重要因素。

Optimizing on multiple constrained QoS multicast routing algorithms based on GA

With the rapid development of Internet, mobile networks and high-performance networking technology,multiple constrained QoS multicast routing optimization in networks with uncertain parameters has become a very important research issue in the areas of networks and distributed systems. It is also a challenging and hard problem to the next generation Internet and high-performance networks, and has attracted the interests of many people. This paper discusses the multiple constrained QoS multicast routing problem, which may deal with the delay, delay jitter,bandwidth and packet loss metrics, and describes a network model for researching the routing problem. The paper mainly presents multiple constrained QoS multicast routing algorithm (MCQMRA), a QoS multicast routing policy for Internet,mobile network or other high-performance networks, which is based on the genetic algorithm (GA) and can provide QoS-sensitive paths in a scalable and flexible wayin the network environment with uncertain parameters. The MCQMRA can also optimize the network resources such as bandwidth, delay, packet loss metrics and can converge to the optimal or near-optimal solution within few iterations, even for the network environment with uncertain parameters. Simulation results show that MCQMRA is an available approach to QoS multicast routing decision.     

基于ns-2的SSM组播模型仿真

组播技术能以高效、可扩展的方式发送点到多点、多点到多点数据。传统的组播模型与协议存在可扩展性差等问题，至今未能在Internet得到广泛应用。新型的SSM组播服务模型，能克服传统组播模型的缺点，有望在Internet上得到广泛应用。本文实现了SSM组播服务模型，并对SSM实现机制进行了分析，利用所实现的SSM组播模型进行了仿真实验，论证了SSM组播模型的简单与高效性。

A survey on routing in wireless sensor networks

One of the most important issues in wireless sensor networks is data delivery service between sensors and the data collection unit (called sink). Although sensor networks and mobile ad hoc networks are similar to some extent, they are radically distinct in many aspects. Sensor networks have many unique features, making them more challenging and need further research efforts. The existing routing protocols for sensor networks can be classified as indicator-based and indicator-free. In this survey, we make a comparative study of these protocols. Open issues and research directions are pointed out as guidelines for our future work.
