网格工作负载中的用户作业特征研究

网格工作负载对研究网格系统具有非常重要的意义。用户作业是构成负载的来源,通过研究用户作业特征,可以对负载进行建模与预测。用户作业的聚合处理方法作为一种新的处理网格工作负载方法能够更加真实地反映出用户的提交行为和作业特性。通过使用3个著名网格的作业负载数据在作业到达时间、作业并行度、作业运行时间和作业等待时间4个方面对网格工作负载特性进行了分析。研究结果表明:新方法有助于进行负载分析和构建新的负载模型。

Changes in the economic fortunes of Pacific Islanders in the USA in the 1990s

Abstract: This paper shows that an important requirement of the MIRAB model, economic success in the host country, is a characteristic of Pacific Islander migrants to the USA and their offspring. Pacific Islanders improved their economic lot in the 1980s and again in the 1990s. Part of this improvement was due to increases in their human capital: Pacific Islanders acquired more education, work experience and better English language skills. This upgrading allowed more workers to acquire white‐collar jobs and to increase their earnings.     

From job training to green jobs: A case study of a young adult employment program centered on environmental restoration in New York City,USA

The demand for a well-trained green-collar labor force will increase as many cities implement sustainability and green infrastructure plans. Additionally, many green jobs training programs are intended to provide pathways out of poverty for low-skilled workers. In this case study, we analyze the experiences of graduates from a New York City, USA green jobs training program targeting 18–24 year olds previously disconnected from the workforce as they transition to full-time employment. Graduates of the program work directly in arboriculture, ecological restoration, landscape design, and horticulture. Despite the well-documented benefits of nature on individual socio-psychological well-being, scant research has investigated the effects of working professionally in urban natural resources management. Our findings reveal the significant challenges facing training program graduates and their supervisors, but also the benefits of urban conservation job training and employment that are potentially transformational for these economically disadvantaged young adults. Green job training and employment present real opportunities for intellectual stimulation and an increased sense of accomplishment, due in part to the uniqueness of environmental work. Individuals reported positive environmental attitudes and behaviors as a result of green jobs training and employment.

借鉴“联众模式”推进渔民向休闲渔业转产转业

“联众模式”是地方政府引进工商业共同参与新农村建设的一种全新尝试。这种尝试以市场为手段,推进了农村土地资源、社会资源、景观资源的优化配置。“联众模式”可以充分发挥渔民自身优势,解决转产转业中的资金匮乏、环境保护、公共产品供给、土地资本化、人力资源优化、渔民再组织等问题,在促进渔业产业结构调整,发挥休闲渔业在生态保护、观光养老休闲、渔文化传承等方面的特殊功能的同时,还吸引了城市的人流、资金流和信息流,实现渔民的就地平滑转移就业,为渔民向休闲渔业转产转业提供一个创新模式、一种经验。     

明清时期农民兼业化趋向研究

中国传统经济条件下,农民主要依靠传统的农业经济维生,自给自足的小农经济是传统农业社会家庭经济的特点。一旦农业经济的收入不足以维持家庭生计,农民就会考虑到从事其他职业,这种行为称为兼业化行为。明清时期处于封建社会晚期,资本主义萌芽已经出现,正处于社会转型期,小农的行为趋向正反映了该时期的历史特点。农民兼业的动因出于压力、需求等因素;而农民的兼业行为一方面对于农民自身的生活条件改善和自身观念的变化带来影响,另一方面为稳定社会秩序和促进社会经济发展等具有重要作用。正确理解明清时期农民的兼业化行为,对于今天建设社会主义和谐社会、妥善解决农民问题具有一定历史借鉴意义。

How to Organize a Large-Scale Ecological Restoration Program? The Framework Developed by the Atlantic Forest Restoration Pact in Brazil

Large-scale ecological restoration programs across the world have begun to extensively transform degraded lands into young native ecosystems. However, more projects like these will be necessary in the coming years to fulfill the goal of restoring 150 million ha established by United Nations Convention on Biological Diversity. Here, we present and discuss the steps required for and the lessons learned from the organization of a large-scale ecological restoration program in Brazil, the Atlantic Forest Restoration Pact. These lessons are organized around 9 steps: (a) the presentation of the motivations driving the promotion of large-scale restoration, (b) the organization of the main stakeholders, (c) the definition of goals, (d) the organization of a database, (e) the indication of both available and priority areas for restoration, (f) the proposal of science-based and field-validated methods, (g) the establishment of a monitoring protocol, (h) the proposal of a communication program to unite members and interact with society, and (i) the strategies for promoting the establishment of public policies conducive to restoration. This framework may provide a template to help other initiatives to mainstream isolated restoration projects into a large and well-organized movement, which may increase the chances of successful restoration in the future.
