(Xinhua/Emmanuel Herman)     Tanzanian President Samia Suluhu Hassan on Saturday inaugurated the 2,115-megawatt Julius Nyerere Hydropower Plant, a landmark project expected to strengthen electricity supply and accelerate industrial and economic development.
Hassan inaugurated the plant in Rufiji District in Coast Region, saying the new generation capacity should produce measurable gains in manufacturing, trade, mining, modern agriculture, public services, investment and employment.
The nine-unit facility now accounts for nearly half of electricity dispatched to Tanzania's national grid, significantly improving reliability and security of supply, she said.
"This project has demonstrated Tanzania's capabilities. We must now harness that capacity to advance other strategic projects and build a strong, self-reliant nation," Hassan said.
Built with the participation of China's Power Construction Corporation of China (PowerChina) and Dongfang Electric Corporation, the plant has a total installed capacity of 2,115 megawatts, Zhang Rui, the project manager with PowerChina, said.
PowerChina undertook the construction of the main works, including the main dam, the stilling basin, the water conveyance system, the diversion tunnels and the metal structures, as well as the overall engineering design and the supporting facilities, Zhang said.
Tan Jin, the project manager with Dongfang Electric, noted that they supplied all nine hydro-turbine generator units, main inlet valves and other complete sets of electromechanical equipment, and carried out their installation, commissioning and trial operation.
During construction, the China-involved construction work created about 14,000 jobs for local residents. Thousands of Tanzanians received professional skills training from Chinese engineers in areas such as welding, steel fixing, carpentry, heavy machinery operation and surveying, helping build a stronger local workforce, according to the two managers.
The project is also expected to improve electricity supply for households and public services, strengthen Tanzania's role in the regional energy market in East Africa, and provide reliable energy support for regional connectivity and socioeconomic development, said Humphrey Moshi, an economics professor at the University of Dar es Salaam in Tanzania.

。　　该平台曾拥有超过50万名工作者，专门承接计算机难以完成的简单数字任务，亚马逊创始人杰夫·贝索斯（Jeff Bezos）因此将其称为“人工AI”。

B | 　　亚马逊在平台网站发布公告称，公司会定期评估各项计划、工具和服务，并根据评估结果做出调整，经过评估后决定关闭这项服务。

C | 亚马逊上月已停止接纳Mechanical Turk新客户，当时不少工作者便将这一变化视为平台即将停止运营的信号。　　Mechanical Turk简称MTurk，于2005年上线，主要将企业发布的“人类智能任务”分配给平台工作者。

D | 每项任务的报酬通常只有几美分，工作内容包括数据标注、音视频转录和填写问卷等。　　该平台的名字源自18世纪的“机械土耳其人”。这台机器表面上能够自动下国际象棋，但实际由藏在内部的棋手操控。有媒体报道称，亚马逊最初推出MTurk，是为了借助人工完成其电商平台的海量数据标注工作。　　亚马逊没有说明关闭MTurk的具体原因。有媒体称，该平台近年来的活跃度和影响力持续下降。人工智能模型已经能够处理部分原本依赖人工完成的简单任务，Scale AI、Mercor和Prolific等数据服务企业也在招募工作者参与模型训练。　　数据工作者权益组织Turkopticon的组织者Krista Pawloski表示，近年来，亚马逊用于改进MTurk的资源似乎有所减少。

E | 随着同类数据标注服务增多，许多工作者开始转向其他平台。　　MTurk能否确保相关任务由人工完成也受到质疑。2023年发布的一项研究显示，在一项摘要生成任务中，研究人员估计有33%到46%的MTurk工作者使用了大语言模型，这意味着部分被视为人工完成的数据可能实际由人工智能生成。

F | 不过研究人员表示，该结果能否适用于其他类型的任务尚不明确。　　亚马逊也曾借助人工智能训练需求推广MTurk，将其作为亚马逊云科技（AWS）旗下机器学习服务SageMaker的数据标注来源。AWS此前介绍，MTurk工作者可以全天候承接任务，有助于加快人工审核和数据标注工作的完成速度。　　Pawloski表示，部分保险公司和旅游公司目前仍依赖MTurk获取数据工作者，平台即将关闭促使这些企业加紧寻找替代服务。

G | 对部分工作者而言，MTurk提供了可以远程完成、工作时间较为灵活的收入来源，目前仍有人将其作为全职工作，平台关闭将直接影响他们的生计。（文章来源：财联社）。
