Keynote Address: No More Fences

ABSTRACT

This speech reviews six major forces that compel agriculture librarians and information specialists to partner with others. It defines five levels of relationships: networking, cooperation, partnership, coalition and collaboration, and then describes in more detail partnerships and why they succeed or fail. It then reviews examples of partnership between Cooperative Extension and other organizations and suggests a number of opportunities for agriculture librarians to form partnerships with external organizations. It challenges agriculture librarians to break down unnecessary barriers to successfully partnering with others and reap the benefits of working with others.     

智能化农业物料输送技术进展与趋势

农业物料输送技术是制约农场智能化应用的重要瓶颈。物料输送主要借助输送设备将物料由加料机输送至受料机中,提高受料机的续航时间,使其路程加大,以确保其高效率、持续性地正常工作。该研究按照物料特性和输送原理,将现有物料输送自动化技术与装备系统地划分为以下4类：固态种苗肥自动输送技术、液态水药燃油自动加注技术、收获物自动收集技术、收获物自动卸载技术,逐一对其研究现状和发展动态进行了重点阐述和深入剖析。总结了自主定位导航、物料流量实时监测及机群实时通信3项智能化物料输送关键技术的研究进展,并结合农场智能化技术要求和应用场景,从形成全生产环节物料输送技术体系、基于时空数据的农田物料需求决策技术、基于农田数字模型和变量作业处方的农机物料丰缺预测技术、物料车多机配送路径动态优化技术角度展望了农场智能化作业多机协同物料配送技术的发展趋势,以期进一步提高农场智能化作业效率、联动性能和应用效果。     

Collaborative Levels and Effecting Factors Analysis for Web-based Product Development

The collaborative levels in modem web - based product development processes are diversed in a large degree. However, current researches are lack of systematic approaches to analyze the appropriate level of the collaboration. Aiming at the problem, the collaborative levels and effecting factors are studied in the paper. First, a primary framework of the effecting factors analysis is proposed, which defines the input, output, and components of the effeeting factors analysis. Next, a collaboration hierarchy model is set up, which is constituted by message level, data level and application level. Based on the model, the effecting factors of collaboration levels are analyzed systematically from technology, organization and business aspects. Detailed indices are abstracted from these aspects and an evaluation factors set is formed systematiclly. According to the framework, hierarchy model, and the factors set, a methodology for factors evaluation and analysis is developed, which contains analytical hierarchy process, fuzzy comprehensive evaluation method and gap analysis method. The methodology has characteristics of quantitive analysis, easy to oprerate, and optimization support capability. A case study is provided to illustrate the analysis process based on the application of the methodology in a collaborative product development project of a furniture enterprise. The case study shows that the methodology can help enterprises to determine the collaboration level effectively, and can also find out the critical factors which impact the collaboration on a large extend. As a result, the develop process, working efficiency and the outcome of the collaborative project can be highly improved.     

基于联盟链的智能温室群数据共享及决策协同方案

针对智能温室群中数据共享和决策执行不可信以及设备决策执行情况无法验证的问题,基于联盟链和人工神经网络等技术,提出了一种智能温室群数据共享及决策协同方案。该方案基于联盟链构建了数据提供方、数据决策方和决策分析方的交互流程;数据提供方利用智能合约技术将时间段内的数据散列上链存储并将数据发送至数据决策方,以链上链下的方式实现数据哈希可验证;数据决策方以经过链上校准的可信智能温室环境数据训练人工神经网络模型,将决策结果存储到链上;决策分析方从链上查询决策结果,调动控制装置执行并上链执行状态。基于Hyperledger Fabric构建了一个原型系统,测试结果表明:1)该方案可以实现数据提供方数据摘要存储及数据共享、决策模型训练、决策数据上链与决策过程的链上执行;2)在区块的最大打包数和最大存储字节确定的条件下,区块打包时间为4 s时,数据存储到联盟链中平均时延最低为30.4 s,吞吐量最大为27.3事务数/s。本方案能够实现智能温室数据的可信共享,提高决策执行结果的真实性验证。     

我国智能水肥一体化系统发展面临的挑战及其对策：基于博弈论的分析

为探索解决我国目前智能水肥一体化系统存在的质量不过硬、设备不智能以及平台不兼容等问题的措施,基于利益相关者理论构建博弈论模型,从供给的角度揭示造成目前我国智能水肥一体化系统发展困境的行为和制度根源,并讨论解决这些问题的可能措施。研究表明：在当前我国智能水肥一体化系统发展水平和市场格局下,面对智能水肥一体化系统相关农机装备的同档定额补贴政策,采取低性能低价格的市场策略成为市场竞争力相对较弱的国内企业在短期内的最优选择,使得国产智能水肥一体化系统整体质量不高;产学研合作中科研人员难以获得充分激励,从而导致对水肥一体化系统智能化研发的投入不足;垄断竞争市场的现状决定了个体企业转换到标准化平台的成本大于潜在收益,导致难以形成水肥一体化系统的统一生产标准。针对上述问题与原因,本研究提出,政府应该优化补贴制度,强化对高性能水肥一体化农机的识别和补贴;完善科研机构考核机制,提升高等院校科研成果转化部门的服务动力;对企业更换产品生产标准给予补贴,引导统一市场标准的建立。

Landscape Conservation Cooperatives: Building a Network to Help Fulfill Public Trust Obligations

The Landscape Conservation Cooperative (LCC) network (Network), comprised of 22 conservation partnerships spanning North America and U.S. Islands, is uniquely positioned to assist government members in fulfilling their public trust obligations to sustain natural and cultural resources for current and future generations by (a) ensuring inclusivity of broad stakeholder participation in conservation decision-making, and (b) building capacity for public trust to work in conservation, thus increasing the chance for successful and lasting conservation outcomes. In this article, we discuss the vision for the Network; challenges individual LCCs and the Network face in achieving the vision of sustaining natural and cultural resources for the benefit of current and future generations, a public trust obligation of most of the members; and ways in which member LCCs are making progress in this regard. We offer recommendations for the Network to consider to improve its ability to meet public trust obligations.     

Walking in STEP: Lessons for linking spatial prioritisations to implementation strategies

Spatial prioritisations are increasingly being undertaken to allocate the investment of limited conservation resources. These techniques are highly effective at identifying where important areas for conservation are located, but of limited use for deciding how implementation of conservation action should be undertaken. Conservation planning should be a collaborative social process, and necessitates that spatial prioritisations be complemented with an implementation strategy. We undertook a conservation planning initiative in the Subtropical Thicket biome in South Africa, complementing a spatial prioritisation with an implementation strategy. Believing strongly in the importance of developing a ‘safe-fail’ culture in conservation, we detail our activities and document our successes and failures. We synthesize lessons from our experience of collaboratively developing an implementation strategy with stakeholders, so as to ensure it effectively complements a spatial prioritisation.
