CDMA技术：正在规模化应用的无线视频监控解决方案

CDMA（码分多址技术）是—项扩展频谱空中接口技术。与GSM使用不同的时隙和频率来分隔呼叫不同，CDMA使用不同的编码分隔每个呼叫，增加了可用话音信道的数量与整个无线通信系统的容量。CDMA被认为是未来的无线技术，因为它能支持一系列新业务，话音品质优异．而且适用于几种无线应用，包括蜂窝移动通信、PCS（个人通信）、无线本地回路（WLL）以及卫星通信。目前，CDMA技术正在城市管理，尤其是视频监控中得到规模化应用。[编者按]

CRIMINOLOGICAL THEORIES AND REGULATORY COMPLIANCE*

Four traditional criminological theories—opportunity, control, subcultural, and differential association—are tested for their explanatory power in accounting for organizational compliance with regulatory laws. The primary data source is interviews with 410 chief executives of small organizations. Partial support is found for each theory; certain key concepts of each theory have a significant effect on regulatory compliance, net of a variety of characteristics of the nursing home, the residents in the home, and the inspection team. The results show that blocked legitimate opportunity has a significant effect on regulatory compliance, as does the structure of illegitimate opportunity. There is also an effect on compliance of participation in business subcultures of resistance to regulation. Belief in laws increases compliance with those laws as does differential association with or attachment to the upholders of the law. Overall, however, control theory and differential association lack explanatory power, and the explanatory power of subcultural theory is modest. Only opportunity theory explains a credible proportion of variance in compliance as a standalone theory. The significant effect of some but not all of the measures for each theory, coupled with the lack of significant explanatory power by three of the four theories, suggests the need for theoretical integration.     

Constructing Legal Order in an Intelligent Society

Legal order originated in a land-centered agricultural society, having now gone through a market-centered industrial society and a network-centered information society. With the rise of the intelligent society, it is transforming into an algorithmcentered legal order of an intelligent society. The “digital” “networking” “intelligent” revolution brought by the intelligent technologies including big data, cloud computing, the Internet, blockchain, and artificial intelligence (AI), has been causing critical challenges to the current legal order, and has generated powerful momentum for construction of fresh legal order featuring scientificness, people centeredness, justice, inclusiveness and co-governance. Construction of such a new jurisprudential legal order to solve this intelligent society’s “governance deficit” is an urgent task. There is a need to set up a new foundation on which an intelligent society can build steady and lasting progress.

伤残鉴定中智能障碍评定的多因素分析

目的探讨智力测验在智力损伤与伤残鉴定中的适应性。方法对366例在精神损伤或伤残鉴定中进行韦氏智力测验的结果及其影响因素进行分析,并与鉴定专家评定结论进行比较。结果①韦氏智力测验结果与专家鉴定结论之间存在明显差异（P〈0．01）,不一致率为68．8％,但二者呈现显著正相关（r=0．431,P〈0．01）。②影响韦氏智力测验的客观因素包括多种身体功能障碍及精神障碍,分别占32．2％（118例）和23．8％（87例）。③在智力测验时表现有主观不合作者为61．5％,而在专家检查中表现有主观不合作者仅为38．8％。结论智力测验受多种主客观因素的影响,不能直接引用评定智力伤残等级,需要结合脑外伤的严重程度、临床检查及社会功能等综合评定智力伤残的等级。     

论网络服务提供者的著作权侵权责任

网络服务提供者在网络信息交流中处于中立第三方地位。在网络用户利用网络服务实施侵害著作权行为的情况下,网络服务提供者作为共同侵权行为的帮助人,承担间接责任。这是一种过错责任,即在网络服务提供者具备"明知"(实际知道)和"应知"(推定知道)的主观要件时所承担的侵权责任;同时,它亦为一种不真正连带责任,事实上由网络服务提供者承担最终责任。

Intelligent agents and intentionality: Should we begin to think outside the box?

The emergence of intelligent software agents that operate autonomously with little or no human intervention has generated many doctrinal questions at a conceptual level and has challenged the traditional rules of contract especially those relating to the intention as an essential requirement of any contract conclusion. This paper will explore some of these challenges, and shine a spotlight on the conflict between the traditional contract theory and the transactional practice in the case of using intelligent software agents. Further, it will examine how intelligent software agents differ from other software applications and then consider how such differences are legally relevant. This paper, however, is not intended to provide the final answer to all questions and challenges in this regard, but to identify the main components and provide perspectives on how to deal with such issues.     

Distributive Justice and the Allocation of Costs,Losses, and Profits

In an experimental study, participants read a scenario about five business partners who sold plants at a flea market. Each partner obtained a different outcome and still had to pay the costs of the partnership. Participants either had to indicate what they considered to be a fair distribution of the costs (given each individual partner's earnings) or what they considered to be a fair distribution of the net results (the total outcome minus the costs). The total outcome was either higher or lower than the costs (i.e., the enterprise resulted in a net profit or a net loss). The results indicate that fairness judgments are affected by the target of distribution. Negative outcomes are distributed differently than positive outcomes, and within the domain of negative outcomes, marked differences are observed between costs and net losses. The results are explained in terms of the differential salience of the distribution of the net result.
