This qualitative research aimed to explore small-scale farmers’ awareness and perception of Smart Irrigation (SI) and Smart Irrigation Technologies (SITs) in the Eastern Cape Province, South Africa, where agriculture significantly contributes to economic activities and labour. These farmers learnt from their families when there was little pressure on water resources and technology not as advanced as today. This intergenerational knowledge cannot address emerging water use pressures to achieve the quality and efficiencies required. In-depth interviews were used to establish small-scale farmers’ awareness and perception of smart farming, especially SI. The farmers know the current irrigation practices are wasteful in water use, crop, and labour. Most of the farmers were aware of the benefits of SITs in reducing over-irrigation, soil erosion, water wastage, and associated decrease in crop yields, which prevents the SITs. Training farmers and assisting them in installing SITs in irrigation would help them achieve most of the benefits of SITs.
这项定性研究旨在探索南非东开普省小农对智能灌溉(SI)和智能灌溉技术(sit)的认识和感知,在那里农业对经济活动和劳动力做出了重大贡献。这些农民向他们的家庭学习,那时水资源压力不大,技术也不像今天这样先进。这种代际知识无法解决新出现的用水压力,以实现所需的质量和效率。通过深度访谈,建立小农对智慧农业,尤其是智能农业的认知和感知。农民们知道目前的灌溉做法在用水、作物和劳动力方面都是浪费的。大多数农民都意识到sit在减少过度灌溉、土壤侵蚀、水资源浪费和相关的作物产量下降方面的好处,这阻碍了sit的发展。培训农民并帮助他们在灌溉中安装sit,将有助于他们获得sit的大部分好处。

Evaluating the Impact of e-Government Initiatives on Citizens: Empowerment or Tokenism? 评估电子政务对公民的影响:赋权还是象征主义?

Evaluation of public sector automation platforms, also known as e-government platforms is complicated due to several incoherent e-government maturity models. Further, these e-government maturity models are not specifically tailored to evaluating e-government platforms from a citizen perspective. A key component of a citizen facing e-government platform is the level to which it enables citizen participation to a level that they feel empowered. This study applied the Arnstein’s ladder of citizen participation to evaluate the e-government platforms in Kenya. The results indicate that the e-government platforms in Kenya are still at the levels of non-participation and tokenism. The e-government platforms are yet to reach the highest level of citizen participation known as citizen empowerment. The study enhances our understanding of e-government evaluation from a citizen view and can be useful to policy makers during the design and implementation of e-government platforms
公共部门自动化平台(也称为电子政务平台)的评估由于几个不一致的电子政务成熟度模型而变得复杂。此外,这些电子政务成熟度模型并不是专门为从公民的角度评估电子政务平台而量身定制的。面向电子政务平台的公民的一个关键组成部分是它使公民参与的程度达到他们感到被授权的程度。本研究运用阿恩斯坦的公民参与阶梯来评估肯尼亚的电子政务平台。结果表明,肯尼亚的电子政务平台仍处于非参与性和象征性的水平。电子政务平台尚未达到公民参与的最高水平,即公民赋权。本研究增进了我们从公民角度对电子政务评估的理解,对电子政务平台的设计与实施有一定的参考价值

This paper analysed 30 NGOs based in Tanzania so as to establish the Digital Knowledge Management gap that exists to their systems. In addition, the paper used the literature of the African origin to determine challenges facing organisations in the implementation of Digital Knowledge Management Systems; this was followed by highlighting opportunities for enhancing the use of Digital Knowledge Management Systems within the continent. The study was descriptive in nature. Results confirmed that Knowledge Management Systems owned by organisations do not meet minimum technical criteria. In addition, there were challenges associated with how to work with the information, there were challenges on how to manage Knowledge Systems, and challenges on how to deal with the technology. The following are the opportunities for enhancing Digital Knowledge Management - the use of Open Sources, engaging higher learning institutions in knowledge management issues, and researching for contents relevant to NGOs.
本文分析了坦桑尼亚的30个非政府组织,以确定其系统存在的数字知识管理差距。此外,本文使用非洲起源的文献来确定组织在实施数字知识管理系统时面临的挑战;随后强调了在非洲大陆加强使用数字知识管理系统的机会。这项研究本质上是描述性的。结果证实,组织拥有的知识管理系统不符合最低技术标准。此外,还有与如何处理信息相关的挑战,还有如何管理知识系统的挑战,以及如何处理技术的挑战。以下是加强数码知识管理的机会-利用开放资源、让高等院校参与知识管理问题,以及研究与非政府组织有关的内容。

A Multilevel Clustering Model for Coherent Topic Discovery in Short Texts 短文本连贯主题发现的多层次聚类模型

Deducing meaning from collections of documents has become an increasingly important task for decision makers, both in industry and academia. To address this challenge, topic modelling techniques have been developed to identify and isolate words that most closely summarise the contents of document collections. However, the topics extracted from collections of short texts by these techniques, achieve low coherence scores, thereby defeating the purpose for which these techniques were created. In this paper, we propose the n-gram_cluster model, a model that exploits the semantic closeness between n-grams and word clusters formed from collections of the n-grams at different levels to discover topics. The model is able to discover semantically coherent topics from collections of short texts. We evaluated the performance of our model against those of three other conventional models showing that it is able to form topics that achieve comparatively higher coherence scores.
从文件集合中推断意义已经成为工业界和学术界决策者日益重要的任务。为了应对这一挑战,主题建模技术已经被开发出来,用于识别和分离最能概括文档集合内容的单词。然而,通过这些技术从短文本集合中提取的主题获得了较低的连贯分数,从而违背了创建这些技术的目的。在本文中,我们提出了n-gram_cluster模型,该模型利用n-gram和由不同层次n-gram集合形成的词簇之间的语义紧密性来发现主题。该模型能够从短文本集合中发现语义一致的主题。我们将我们的模型与其他三种传统模型的性能进行了评估,表明它能够形成获得相对较高连贯分数的主题。
