基于手机和网络平台的新疆农业技术服务创新模式

农业技术的社会化服务水平将是新疆农业发展中的关键。文章基于新疆10个县（市）784个农户的实地调查数据,分析了新疆现有农业技术服务模式的不足,调查了农户对基于手机和网络平台的农业技术服务新模式需求意愿状况。在此基础上,拟定了新疆＂手机＋网络＋农户＂的农业技术服务创新模式的设计思路和实用性、便捷性、主体引导的原则;构建了基于手机和网络平台的新疆农业技术服务创新模式,该模式主要包括专家系统的建立、农业技术需求路径的建立、农业技术反馈路径的建立;提出了政府部门应当给予资金和技术的投入,农业服务提供商在给予资金和技术投入的同时应提供农资和技术服务的政策建议。     

音素与音位关系辨

音素是从音质的角度对语音进行切分所得到的最小的(语音)单位;音素的概念是局限在音质内部的范畴;音位是一种语言中可以区别意义的最小语音单位,含有一定的社会属性,它既有音素的音质形式,又处于一个音位体系中,一定要考虑不同音位之间的关系,音位才有意义。音位变体依然有音位的性质,音节是由音位和调位、时位、重位等按照一定语言的组合规则组合而成的,而不是由音素组成的。     

青少年手机沉迷的形成与矫正

现阶段,数字通讯技术日臻完善,媒介融合进一步深化,手机日益渗透到社会的各个角落。随之而衍生的手机过度性、病态性使用等现象日渐凸显,尤其是处于社会化过渡阶段的青少年,手机沉迷现象表现得更为突出。需要不断尝试,从行为主体、客体及环境三个方面采取相应措施进行适度干预,积极引导青少年的手机使用行为,使手机这一时代高科技产物真正成为整个社会的福音。

Real-World Personal Conversations Using a Hands-Free Embedded Wireless Device While Driving: Effect on Airbag-Deployment Crash Rates

A wireless device embedded in the vehicle allowed the user to engage in a personal hands-free conversation (HFC), and automatically placed an emergency notification call to an OnStar call center if the vehicle was involved in a crash in which its airbag deployed. A database stored the exact counts, start timestamps, and billed durations of all HFC and airbag notification calls. In 30 months of naturalistic driving, there were 91 million HFC calls from an average of 323,994 drivers per month who made calls. There were 14 airbag deployments in 276 million driver-minutes of HFC conversation for an exposed incidence rate of 5.08 airbag crashes per 100 million driver-minutes. There were 2,023 airbag deployments in an estimated 24.7 billion driver-minutes of no HFC conversation for a not-exposed incidence rate of 8.18 airbag crashes per 100 million driver-minutes. The crash incidence rate ratio (IRR) is the ratio of these two rates or 0.62 (95% C.I. 0.37 to 1.05). Sensitivity analyses controlled for the impact on the crash IRR of estimated time spent driving per day and calls by passengers. Counting all crashes as much as 20 minutes later than a call as related to that call gave similar results. We conclude that for personal conversations using a hands-free embedded device the risk of an airbag crash is somewhere in a range from a moderately lower risk to a risk near that of driving without a recent personal conversation. These results are not consistent with the large increase in crash risk reported in epidemiological studies using the case-crossover method.     

国内Android定制手机系统中的版权困境及其应对

Android操作系统作为占据国内市场份额最大的一套移动智能终端操作系统,以其开源性获得了国内众多手机系统开发企业的青睐。但是,具体分析Android系统各组成部分的版权机制,可以发现国内企业在对这样一款开源操作系统进行定制时仍面临着诸多版权问题,如开源协议的法律效力不甚明确、手机系统自身存在的版权瑕疵、追责困难等。针对上述问题,我国应当从立法上对开源软件权利义务关系进行规范,同时引导国内手机系统开发企业建立相应的行业协会,真正走上自主研发智能手机操作系统的道路。     

手机互联网依赖与心理和谐的关系:自尊的中介作用

为探讨大学生手机依赖、自尊和心理和谐的关系,文章采用大学生手机依赖量表、整体自尊量表和大学生心理和谐量表对442名大学生进行测量。结果发现:(1)大学生手机依赖与心理和谐和自尊均显著负相关,心理和谐与自尊显著正相关;(2)高自尊组大学生心理和谐水平均显著高于低自尊组,高手机依赖组大学生心理和谐水平均显著低于低手机依赖组;(3)大学生手机依赖和自尊可以显著预测心理和谐;(4)自尊在手机依赖与心理和谐之间起到中介作用,结构方程模型指标拟合较好。因此,手机依赖通过自尊间接影响心理和谐,进而影响大学生的心理健康,可以通过改善大学生的自尊水平来提高手机依赖者的心理和谐及心理健康水平。     

Development of the MyPlan Safety Decision App with Friends of College Women in Abusive Dating Relationships

Dating violence (DV) from an intimate partner/expartner is common on college campuses, but young college women are far more likely to disclose DV to a peer than to seek formal services. Therefore, our team developed a prototype smartphone application (app) aimed at DV survivors’ peers. Through focus groups/interviews, 31 college students who self-identified as friends of DV survivors reviewed and provided feedback on the app's usefulness, understandability, appropriateness, and comprehensiveness. These findings support the acceptability and usefulness of an app to support peers of DV survivors on campus and thereby also strengthen the safety net for DV survivors.     

Disability citizenship and independence through mobile technology? A study exploring adoption and use of a mobile technology platform

This article explores the use of a mobile technology platform as experienced by people with disability, their significant other and service providers. An interpretive qualitative study design was adopted involving observations and interviews. The data were analysed using the combined lenses of the social approach to disability and the PHAATE model which represents the factors for consideration in service design for assistive technology. The findings suggest that the adoption of the technology by those in the study could be characterised by a typology of users. The implications of the typology are discussed together with the influencing factors that affected social participation and disability citizenship.
