A Research on Mobile Terminal Promotion Based on Big Data of Zhejiang Telecom [PDF]
, 2016 2008年，中国电信业进行了重组，全面形成了中国电信、中国移动、中国联通三家综合性运营商全业务营销的模式，同时也意味着中国电信业打破垄断经营机制，形成了全面竞争的格局。八年来，中国电信在面临三大运营商之间竞争不断加剧的势态的同时，持续加快3G和4G网络的建设，加大手机移动用户的发展，以终端引领移动业务的发展，在移动业务市场上占有了一席之地。 然而，受国家政策指引，通信行业的资费在不断进行下调，近年来陆续实施了接听免费、漫游资费下调、宽带资费下调、流量不清零等政策，使得话音、宽带 ...

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, EarlyView.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Research on The Construction of Archives Big Data from The Perspective of National Governance [PDF]
, 2016 摘要 当前，大数据已成为国家的重大战略，大数据资源和技术成为国与国之间竞争的高地。国际上曾有人将大数据比作“未来的石油”，但相比而言，石油是不可再生的资源，而数据却是源源不断，拥有无限潜力的资源。 大数据时代，政府已成为最大的数据生产者和拥有者，而政府的档案部门（包括各类机关档案室、部门档案馆、专业档案馆和综合档案馆等）则是政府部门中最大的数据集散地。从法定职责来说，各单位、组织的数据最终要归于档案部门。而且，由于数据的原始性、完整性、权威性、长期保存性以及档案部门相对中立的机构特性等 ...

Research On The Decision Support System Of Smart Government Based On Data Warehouse [PDF]
, 2016 在电子政务阶段，我国已经开始利用计算机技术建设决策支持系统以辅助政府决策，使政府从主观、经验式的传统决策向靠数据说话、用数据决策的电子政务决策发展。随着电子政务的不断发展，政府业务内容和业务能力的不断提升，电子政务系统中聚集了海量数据，除了以结构化数据为主体，还包括半结构化、非结构化的数据。在此基础上，电子政务决策支持系统尤其是其核心技术数据仓库已经无法满足政府的业务需求。近年来，随着“智慧城市”、“互联网+”、“云计算”、“大数据”等概念的不断推出 ...

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Analysis and Design of a District Trade and Industry Bureau Information Working Platform [PDF]
, 2015 党的十八届三中全会提出了要“整合科技规划和资源，完善政府对基础性、战略性、前沿性科学研究和共性技术研究的支持机制”的目标。国务院总理李克强在国家工商总局调研考察时强调：“要利用‘大数据平台’等现代手段，为事中事后监管探索新路，做公平市场的‘守护神’。[1]”总理的讲话，为工商行政管理部门工作勾画出了加强市场监管的整体框架、方法途径和有效载体。工商行政管理长期以来的工作还处于信息口口相传、数据资料手写纸质保存、单一窗口服务等落后状态。受制于这种状态的工商行政管理部门，工作中时常出现效率低下 ...

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership
