越来越多地,生物工程和机器人技术领域的研究人员和专业人士面临着这样的道德问题。因此,本课程的目标是双重的:发展博士学位学生对研究和专业实践中出现的道德问题的敏感性,并为他们提供知识和工具,以帮助他们导航道德上复杂的情景。
P&W的Middletown,CT喷气发动机制造,组装和测试设施由于老化的蒸汽产生基础设施和锅炉而面临许多运营挑战。随着能源成本和石油价格上涨,该设施需要更高效,更便宜,更绿色的方式来提供可用的能源。
2023 年,企业和家庭面临重大挑战,主要源于通胀压力的普遍影响。尽管与 2022 年相比,通胀率有所下降,但通胀率仍维持在高位。尽管面临挑战,2023 年各经济部门仍出现大幅反弹,尤其是旅游业,最近获得的信息显示,2023 年是希腊旅游业表现出色的一年,无论是入境人数还是收入,都超过了 2019 年的历史最高水平。此外,该国在过去一年中取得的关键成就是标准普尔和惠誉将希腊共和国的信用评级恢复为投资级,标志着 13 年“垃圾级”的结束。此次升级主要归因于希腊主权债务负担大幅减少、持续改革计划的有效实施、财政平衡的改善、强劲的经济增长、银行资产负债表健康状况的改善以及欧盟随时可用的资源的持续利用。
航天飞机在上升过程中面临着许多飞行器控制挑战,轨道器在轨道和下降过程中也面临着许多挑战。这些挑战需要创新,例如电传操纵、稳健系统的计算机冗余、开环主发动机控制和导航辅助。这些工具和概念带来了突破性技术,这些技术目前正用于其他太空计划,并将用于未来的太空计划。其他政府机构以及商业和学术机构也在使用这些分析工具。NASA 在开发航天飞机主发动机仪器方面面临着重大挑战 - 发动机在当时前所未有的速度、压力、振动和温度下运行。NASA 开发了支持航天飞机导航和飞行检查的独特仪器和软件。此外,航天飞机上使用的通用计算机具有静态随机存取存储器,这容易受到存储器位错误或宇宙射线位翻转的影响。这些位翻转带来了巨大的挑战,因为它们有可能对车辆控制造成灾难性的影响。
联合国表示,基础科学将帮助我们实现可持续发展并改善生活质量。事实上,这份联合国文件强调了新兴技术的重要性,因为它们“响应人类的需求[...]增进个人、社区和社会的健康和福祉” [3]。去年,世界以前所未有的方式应对气候危机的后果——致命的热浪在春季袭击了印度和巴基斯坦,欧洲在有记录以来最热的夏季也面临着类似的挑战。此外,我们仍在承受 COVID-19 大流行和新的传染性变种,以及乌克兰战争的后果——其中包括油价飞涨。因此,今年的技术深入研究了创新的医疗解决方案和高效的能源。IUPAC 召集的专家小组审查了来自世界各地化学家的大量建议,并选出了最有希望的提案。像往常一样,这些新兴技术徘徊于实验性和商业现实之间,但它们都有望改变我们的世界。
自上一份全球脊髓灰质炎监测行动计划(GPSAP)(2018-2020 年)以来,现场和实验室监测面临着新的挑战。2019 年末出现严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)以及随后爆发的 COVID-19 全球大流行,导致许多国家暂停了脊髓灰质炎监测活动。虽然监测绩效在大流行的头几个月有所下降,但 2020 年检测到的脊髓灰质炎病毒数量创下了历史新高,反映出因暂停疫情应对活动而导致的广泛挫折。然而,在 COVID-19 之前,许多国家在国家以下各级脊髓灰质炎病毒监测方面仍然存在一些差距。在一些国家,监测绩效不佳的情况更多地局限于难以到达的地区和无法获得正规卫生部门服务的高危人群。除了这些挑战之外,一些国家还面临着人力和财力资源有限的问题,这是由于他们将脊髓灰质炎监测资产转移到其他公共卫生优先事项(包括新冠肺炎)上,或当前的财政环境导致 GPEI 对各国的支持减少。
摘要在沙特阿拉伯王国(KSA)中,定性研究方法很少采用,因为该地区的研究人员更习惯于定量方法,并且犹豫不决地接受定性方法。这项研究努力致力于探索在沙特背景下从事定性研究的个人所面临的障碍。为此,我对八名博士生进行了半结构化访谈,并为本文采用了定性案例研究设计。使用MAXQDA软件,我还将主题分析应用于访谈中收集的数据。主要发现重点介绍了三个重要主题:(a)与组织方面相关的挑战,(b)源于社会和文化因素引起的困难,以及(c)针对定性研究实践的障碍。本文在该地区的贡献方面独一无二,解决了定性研究人员面临的广泛问题,以支持和增强其研究工作。这项研究与研究人员有关,但其意义显着扩展到KSA中的决策者,学者和高等教育机构。
