Let's consider the management of the actual pandemic first. Data must be gathered, processed, and distributed, not only to public-health, medical, and political personnel, but also to the general public. People need/want to know information about daily new cases, daily new deaths, local hospital capacity, and many other items. The hospitals must be prepared to coordinate with each other; perhaps one hospital is full, and new patients must be diverted; there are many other ways in which hospitals must coordinate. In Los Angeles, where I live, in order to create additional hospital capacity, local hotels have been converted to isolation wards, where patients who test positive for Covid-19 but (at least, for the present) are asymptomatic or do not require any extensive medical treatment are kept. This procedure – which is very important, because it materially reduces the demand for beds within the actual hospitals – requires electronic communications to new locations, ones that are not traditionally a part of the medical system. Testing for Covid-19 is also generally done at locations that are not a part of the traditional medical system, such as parking lots that offer drive-up testing; people do not even leave their cars. Many other improvisations to improve medical capacity, and to optimize utilization of trained people and facilities, are underway, and all of these require electronic communications for planning, monitoring, and management.</p><p>Note that these improvised extensions to medical communications and data system must still comply with existing laws and regulations regarding patient privacy and the security of medical records in electronic form.</p><p>Only a small portion of the population is actually sick with Covid-19 at any given time, but almost all of us have been affected by safer-at-home orders, orders closing schools and businesses, orders changing the way that other businesses operate, and so forth. This aspect, while not directly a matter of healthcare or public health management, literally affects nearly everyone in the world at this time. Let's consider the role of electronic communications in this aspect of the pandemic.</p><p>According to data about surges in on-line ordering, many people are ordering groceries on-line, and having those groceries delivered directly to their house. Another method that is increasing in popularity is ordering groceries on-line, and then driving to the grocery store, where the groceries are brought out to your car, and placed into the trunk (boot) of your vehicle, without you ever having to get out of the vehicle. Public health authorities have indicated that both of these methods to acquire groceries are safer than going to the grocery store yourself. Purchasing groceries on-line was not a widespread phenomena in my area before the Covid-19 outbreak, so this is an example of a new adaptation, and of course, this mechanism only works when there are reliable electronic communications systems in place.</p><p>At present, I am a professor of engineering at a university, and in the spring 2020 semester, I was teaching two undergraduate classes. These were being conducted as traditional in-person classes, each with 35 students. The students and I enjoyed meeting face-to-face, and were moving appropriately through the class materials.</p><p>In early March, of course, all that changed: the university mandated that as of 11 March 2020, all classes would be taught exclusively on-line. Fortunately, I had taught on-line before, and was able to make the change. Of course, teaching on-line depended <i>entirely</i> on electronic communications. One aspect that was very important but not obvious at the start (at least, not to me!) was that my students would quickly be dispersed; the university no longer thought that it was safe to have large numbers of undergraduate students in their fairly high-density on-campus housing. So, students moved home; more than 80% of my undergraduate students were U.S. citizens, and so moved to various places around the U.S., but the remainder of my undergraduate students were citizens of other countries, and some of them elected to return to their home countries. Suddenly, not only was I teaching on-line, but I had students spread across the globe, some literally in time-zones 12 h different than Los Angeles, and some in locations with less-than-optimal internet connection.</p><p>With a little experimentation, my students and I figured out how to make all of this work, even across time-zones and to locales with slower/less-reliable internet connections. It took a little more of my time (even allowing for the time-savings of not having to drive to and from campus), but the results were good: the students did as well on their homework and examinations as students from previous semesters.</p><p>And of course, we are all interested in overcoming the pandemic, through improved treatment, better interim protections, and vaccines. The research teams that are doing all of these things are operating at least in part in a geographically-distributed fashion, connecting and coordinating their efforts through electronic communications. The limitations of such geographically-distributed science and engineering have been studied; I myself have published papers on the subject [\"Collaborative Creation of Engineering Artifacts by Geographically-Distributed Teams\", Neil Siegel and Azad Madni, 17th Annual Conference on Systems Engineering Research (CSER). Available at https://neilsiegel.usc.edu/contributions-to-the-literature/.]. Despite these limitations, these teams are moving forward. I myself started a research project on Covid-19 that involves experts from both the school of engineering and the school of medicine at my university; interestingly, I have never met <i>any</i> of my collaborators in person! I approached the Dean with my idea for a project, and he introduced me to a key person in another department of the school of engineering, and to the Dean of the school of medicine, and through them, I found my collaborators. All of our planning, coordination, modeling, research, publication, and assessment has taken place over the internet. There are some of our team members who do experimental work, both on campus and in the hospital, and they then bring their findings to the rest of the team via the internet. Someday, I hope to meet all of these wonderful people in person!</p><p>I believe that some of these new roles for electronic communications in our lives ought to endure once the pandemic has been overcome. I hope, for example, that more people will continue to work from home for some portion of the time; the in-person contact of physically-co-located work is vitally important to creating good team-work, but the benefits of reduced commuting, less pollution, and better work-life balance provided by home work ought to be retained at some level. The opportunity for geographically-distributed collaboration is profound in fields far beyond the examples that I cited above in engineering, science, and education; for example, my wife teaches dancing; she now has twice-weekly classes with attendees from all over the world. I also would like to see the old model of all-in-person instruction at universities change to a better balance between in-person and remote instruction; students can time-shift lectures, interact with their instructors via chat, and collaborate with other students at a distance for some portion of the time. This will involve significant changes to the economic models of universities that have invested heavily in on-campus housing (e.g., perhaps alternate semesters of in-person and remote); over time, this could significantly lower the cost of college education. I believe that education for younger students should involve more remote learning, too. My niece is taking high-school chemistry this summer; the remote learning model worked far better for her than an in-person model would have, as she benefited enormously from the opportunity to move at her own rate, to re-work homework multiple times, and so forth. Hybrid models of education that blend in-person and remote learning are likely to be superior to today's all-in-person models, with their built-in expectations that every student can learn at the same rate.</p><p> <b>Neil Siegel</b>, Ph.D. is the IBM Professor of Engineering Management at the University of Southern California's Viterbi School of Engineering, in the department of Industrial and Systems Engineering.

摘要

在正常情况下,电子通信对我们大多数人来说当然是一个很大的便利,它提供信息,与家人和朋友联系,进入网上商务,以及许多形式的娱乐。电子通信在非名义情况下发挥更重要的作用。在火灾、内乱、地方紧急情况等期间,此类电子通信构成了应急规划、协调和管理的支柱。这就是收集数据的方式,使适当的当局能够理解不断发展的问题、制定响应、实现响应、收集可用于调整响应的附加数据,等等。事实上,在某些类型的紧急情况下,没有这种电子通信就根本不可能进行恢复。例如,电力基础设施安全委员会[https://www.eiscouncil.org/]分析了可能导致大规模(次大陆和大陆规模)电力中断的事件;如果发生如此大规模的停电,如果没有某种形式的电子通信,几乎不可能重新启动电网。被电力基础设施安全委员会确定为此类大规模停电潜在触发因素的事件包括对配电设备的网络攻击和电磁脉冲事件(可以是自然的,也可以是人为的)。在他们的书《电力基础设施保护(E-PRO)手册III》中[Paul Stockton主编;作者保罗·斯托克顿和尼尔·西格尔。电力基础设施安全委员会,2018年。关于紧急电子通信系统的章节可在https://neilsiegel.usc.edu/contributions-to-the-literature/]找到,他们描述了可能导致如此大规模中断的场景(他们称之为“黑色天空事件”),并描述了一套政策和技术步骤,通过这些步骤可以减少此类事件发生的可能性,并且在此类事件发生时也可以更快地实施恢复。事实上,他们所描述的在这种黑暗天空事件中促进恢复的关键技术是一种紧急通信系统,该系统可以在这种停电中幸存下来,并且即使在没有常规电网供电的情况下也能够运行一段时间。拥有这样一个紧急通信系统的能力将通过实现更快的恢复来挽救数十万人的生命。因此,电子通信系统不仅仅是一种便利和娱乐的来源!让我们来看看电子通信系统在当前Covid-19大流行中的作用。让我们首先考虑实际大流行的管理。必须收集、处理和分发数据,不仅要提供给公共卫生、医疗和政治人员,而且还要提供给公众。人们需要/想要了解关于每日新增病例、每日新增死亡病例、当地医院容量和许多其他项目的信息。各医院必须做好相互协调的准备;也许一家医院已经满了,必须转移新病人;医院必须协调的方式还有很多。在我居住的洛杉矶,为了增加医院容量,当地的酒店已被改造成隔离病房,那些Covid-19检测呈阳性但(至少目前)无症状或不需要任何广泛治疗的患者被关押在那里。这一程序非常重要,因为它大大减少了实际医院对床位的需求,它需要与传统上不属于医疗系统一部分的新地点进行电子通信。Covid-19检测通常也在不属于传统医疗系统的地点进行,例如提供驾车检测的停车场;人们甚至不会离开他们的车。为了提高医疗能力和优化训练有素的人员和设施的利用,正在采取许多其他临时措施,所有这些都需要电子通信来进行规划、监测和管理。请注意,这些医疗通信和数据系统的临时扩展仍然必须符合有关患者隐私和电子形式医疗记录安全的现行法律法规。在任何时候,实际上只有一小部分人感染了Covid-19,但几乎所有人都受到了安全在家的命令、关闭学校和企业的命令、改变其他企业运营方式的命令等等的影响。这一方面,虽然不是医疗保健或公共卫生管理的直接问题,但实际上影响着世界上几乎每个人。让我们考虑一下电子通信在这一流行病的这一方面的作用。 根据在线订购激增的数据,许多人在网上订购杂货,并将这些杂货直接送到他们的家里。另一种越来越受欢迎的方法是在网上订购食品杂货,然后开车去杂货店,在那里,食品杂货被带到你的车里,并放在你的车的后备箱(行李箱),你甚至不必下车。公共卫生当局表示,这两种购买食品杂货的方法都比自己去杂货店更安全。在新冠疫情爆发之前,在我所在的地区,网上购买杂货并不是一种普遍现象,所以这是一种新的适应方式,当然,这种机制只有在有可靠的电子通信系统的情况下才有效。目前,我是一所大学的工程学教授,在2020年春季学期,我教两个本科班。这些课程以传统的面对面授课的方式进行,每堂课有35名学生。我和学生们都很喜欢面对面的交流,并且在课堂上进行了适当的交流。当然,在3月初,一切都改变了:该大学规定,从2020年3月11日起,所有课程都将完全在线授课。幸运的是,我以前在网上教过课,所以能够做出改变。当然,在线教学完全依赖于电子通讯。有一个方面非常重要,但一开始并不明显(至少对我来说不是!),那就是我的学生很快就会分散;这所大学不再认为在高密度的校内宿舍里容纳大量本科生是安全的。所以,学生们搬回家;我的本科生中有80%以上是美国公民,因此他们搬到了美国各地,但我的本科生中其余的是其他国家的公民,其中一些人选择回到他们的祖国。突然之间,我不仅是在线教学,而且我的学生遍布全球,有些人在与洛杉矶不同的时区12小时,有些人在互联网连接不太理想的地方。通过一些实验,我和我的学生们想出了如何使所有这些工作,甚至跨越时区和互联网连接速度较慢/不太可靠的地区。这多花了我一点时间(甚至考虑到不用开车往返校园所节省的时间),但结果很好:学生们的家庭作业和考试成绩和前几个学期的学生一样好。当然,我们都有兴趣通过改进治疗、更好的临时保护和疫苗来克服大流行。从事所有这些工作的研究团队至少在一定程度上以地理分布的方式运作,通过电子通信连接和协调他们的努力。对这种地理分布的科学与工程的局限性进行了研究;我自己也发表过关于“通过地理分布团队协作创建工程工件”的论文,Neil Siegel和Azad Madni,第17届系统工程研究年会(CSER)。网址:https://neilsiegel.usc.edu/contributions-to-the-literature/]。尽管存在这些限制,但这些团队正在向前发展。我自己启动了一个关于Covid-19的研究项目,包括我所在大学工程学院和医学院的专家;有趣的是,我从来没有见过我的合作者!我带着我的项目想法去找院长,他把我介绍给了工程学院另一个部门的关键人物,还有医学院的院长,通过他们,我找到了我的合作者。我们所有的计划、协调、建模、研究、出版和评估都是在互联网上进行的。我们的一些团队成员在校园和医院里做实验工作,然后他们通过互联网把他们的发现带给团队的其他成员。有一天,我希望能亲自见到所有这些了不起的人!我认为,一旦战胜了这一流行病,电子通信在我们生活中的一些新作用应该继续存在。例如,我希望更多的人在一定时间内继续在家工作;在同一地点工作时的面对面接触对于创造良好的团队合作至关重要,但在家工作所带来的减少通勤、减少污染和更好的工作与生活平衡的好处应该在某种程度上得到保留。地理分布协作的机会在我上面提到的工程、科学和教育领域之外的领域意义深远;例如,我妻子教舞蹈;她现在每周上两次课,学员来自世界各地。 我也希望看到大学里面对面教学的旧模式转变为面对面和远程教学之间更好的平衡;学生可以在课堂上进行时间转换,通过聊天与教师互动,并在一定时间内与其他学生进行远程协作。这将涉及对大学的经济模式的重大改变,这些大学在校园住房方面投入了大量资金(例如,可能是面对面和远程的交替学期);随着时间的推移,这将显著降低大学教育的成本。我认为,对低年级学生的教育也应该包括更多的远程学习。我侄女今年夏天要上高中化学课;对她来说,远程学习模式比面对面学习模式要有效得多,因为她从以自己的速度移动的机会中受益匪浅,可以多次重新完成作业,等等。融合了面对面和远程学习的混合教育模式可能比今天的全面对面模式更优越,因为它们的内在期望是每个学生都能以相同的速度学习。尼尔·西格尔博士是南加州大学维特比工程学院工业与系统工程系的IBM工程管理学教授。他曾担任诺斯罗普·格鲁曼公司信息系统部门的副总裁兼首席技术官。他领导该部门的技术活动,为该部门的研究组合提供监督,并监督公司最复杂和最重要问题的解决方案的开发。在此之前,他是该部门的副总裁兼总工程师;在此职位上,他负责监督该部门的12,000多名科学家和工程师,指导工程流程改进,并领导旨在进一步发展公司顶级技术人才的活动。此前,他曾担任诺斯罗普·格鲁曼公司任务系统部门的副总裁兼首席技术官,以及公司战术系统部门的副总裁兼总经理。他曾负责美国以外的几个项目,包括在英国、埃及、德国、土耳其和沙特阿拉伯的工作。他是美国国家工程院的当选成员,IEEE院士,美国国家发明家学院院士,美国陆军圣巴巴拉勋章的IEEE西蒙·拉莫奖章获得者,以及许多其他荣誉。更多信息请访问neilsiegel.usc.edu。

The role of electronic communications during the pandemic

In normal times, electronic communications are, of course, a great convenience to most of us, providing information, connectivity to family and friends, access to on-line commerce, and many forms of entertainment.

Electronic communications play a much more important role in off-nominal situations. During fires, civil unrest, local emergencies, and so forth, such electronic communications form the backbone of response planning, coordination, and management. That is how data are gathered that allows the appropriate authorities to understand the evolving problem, to craft a response, to implement the response, to gather additional data that can be used to adjust the response, and so forth.

In fact, in certain types of emergency situations, recovery is simply not possible without such electronic communications. For example, the Electric Infrastructure Security Council [https://www.eiscouncil.org/] has analyzed events that could cause large-scale (sub-continental- and continental-scale) outages of electric power; if such a large-scale outage were to come to pass, it is literally impossible to re-start the electric power grid without some form of electronic communications.

Events that were identified by the Electric Infrastructure Security Council as potential triggers for such large-scale power outages include cyber attacks on electric power distribution equipment, and electro-magnetic pulse events (which can be both natural, and human-induced). In their book “Electric Infrastructure Protection (E-PRO) Handbook III”[Paul Stockton, editor-in-chief; Paul Stockton and Neil Siegel, authors. Electric Infrastructure Security Council, 2018. The chapter on emergency electronic communications systems is available at https://neilsiegel.usc.edu/contributions-to-the-literature/] they describe the scenarios that can cause such large-scale outages (which they call “black sky events”), and describe a set of policy and technical steps by which both the likelihood of such events can be lessened, and also by which – in case such an event happened – recovery can be implemented faster.

In fact, the key technology that they describe for facilitating recovery in the event of such a black-sky event is an emergency communications system that would survive such an outage, and be able to operate for a material period of time even in the absence of electric power from the regular power grid. The ability to have such an emergency communications system would save hundreds of thousands of lives, by enabling far-faster recovery. So, electronic communications systems can be more than a convenience and a source of entertainment!

Let's look at the role of electronic communications systems in the current Covid-19 pandemic. Let's consider the management of the actual pandemic first. Data must be gathered, processed, and distributed, not only to public-health, medical, and political personnel, but also to the general public. People need/want to know information about daily new cases, daily new deaths, local hospital capacity, and many other items. The hospitals must be prepared to coordinate with each other; perhaps one hospital is full, and new patients must be diverted; there are many other ways in which hospitals must coordinate. In Los Angeles, where I live, in order to create additional hospital capacity, local hotels have been converted to isolation wards, where patients who test positive for Covid-19 but (at least, for the present) are asymptomatic or do not require any extensive medical treatment are kept. This procedure – which is very important, because it materially reduces the demand for beds within the actual hospitals – requires electronic communications to new locations, ones that are not traditionally a part of the medical system. Testing for Covid-19 is also generally done at locations that are not a part of the traditional medical system, such as parking lots that offer drive-up testing; people do not even leave their cars. Many other improvisations to improve medical capacity, and to optimize utilization of trained people and facilities, are underway, and all of these require electronic communications for planning, monitoring, and management.

Note that these improvised extensions to medical communications and data system must still comply with existing laws and regulations regarding patient privacy and the security of medical records in electronic form.

Only a small portion of the population is actually sick with Covid-19 at any given time, but almost all of us have been affected by safer-at-home orders, orders closing schools and businesses, orders changing the way that other businesses operate, and so forth. This aspect, while not directly a matter of healthcare or public health management, literally affects nearly everyone in the world at this time. Let's consider the role of electronic communications in this aspect of the pandemic.

According to data about surges in on-line ordering, many people are ordering groceries on-line, and having those groceries delivered directly to their house. Another method that is increasing in popularity is ordering groceries on-line, and then driving to the grocery store, where the groceries are brought out to your car, and placed into the trunk (boot) of your vehicle, without you ever having to get out of the vehicle. Public health authorities have indicated that both of these methods to acquire groceries are safer than going to the grocery store yourself. Purchasing groceries on-line was not a widespread phenomena in my area before the Covid-19 outbreak, so this is an example of a new adaptation, and of course, this mechanism only works when there are reliable electronic communications systems in place.

At present, I am a professor of engineering at a university, and in the spring 2020 semester, I was teaching two undergraduate classes. These were being conducted as traditional in-person classes, each with 35 students. The students and I enjoyed meeting face-to-face, and were moving appropriately through the class materials.

In early March, of course, all that changed: the university mandated that as of 11 March 2020, all classes would be taught exclusively on-line. Fortunately, I had taught on-line before, and was able to make the change. Of course, teaching on-line depended entirely on electronic communications. One aspect that was very important but not obvious at the start (at least, not to me!) was that my students would quickly be dispersed; the university no longer thought that it was safe to have large numbers of undergraduate students in their fairly high-density on-campus housing. So, students moved home; more than 80% of my undergraduate students were U.S. citizens, and so moved to various places around the U.S., but the remainder of my undergraduate students were citizens of other countries, and some of them elected to return to their home countries. Suddenly, not only was I teaching on-line, but I had students spread across the globe, some literally in time-zones 12 h different than Los Angeles, and some in locations with less-than-optimal internet connection.

With a little experimentation, my students and I figured out how to make all of this work, even across time-zones and to locales with slower/less-reliable internet connections. It took a little more of my time (even allowing for the time-savings of not having to drive to and from campus), but the results were good: the students did as well on their homework and examinations as students from previous semesters.

And of course, we are all interested in overcoming the pandemic, through improved treatment, better interim protections, and vaccines. The research teams that are doing all of these things are operating at least in part in a geographically-distributed fashion, connecting and coordinating their efforts through electronic communications. The limitations of such geographically-distributed science and engineering have been studied; I myself have published papers on the subject ["Collaborative Creation of Engineering Artifacts by Geographically-Distributed Teams", Neil Siegel and Azad Madni, 17th Annual Conference on Systems Engineering Research (CSER). Available at https://neilsiegel.usc.edu/contributions-to-the-literature/.]. Despite these limitations, these teams are moving forward. I myself started a research project on Covid-19 that involves experts from both the school of engineering and the school of medicine at my university; interestingly, I have never met any of my collaborators in person! I approached the Dean with my idea for a project, and he introduced me to a key person in another department of the school of engineering, and to the Dean of the school of medicine, and through them, I found my collaborators. All of our planning, coordination, modeling, research, publication, and assessment has taken place over the internet. There are some of our team members who do experimental work, both on campus and in the hospital, and they then bring their findings to the rest of the team via the internet. Someday, I hope to meet all of these wonderful people in person!

I believe that some of these new roles for electronic communications in our lives ought to endure once the pandemic has been overcome. I hope, for example, that more people will continue to work from home for some portion of the time; the in-person contact of physically-co-located work is vitally important to creating good team-work, but the benefits of reduced commuting, less pollution, and better work-life balance provided by home work ought to be retained at some level. The opportunity for geographically-distributed collaboration is profound in fields far beyond the examples that I cited above in engineering, science, and education; for example, my wife teaches dancing; she now has twice-weekly classes with attendees from all over the world. I also would like to see the old model of all-in-person instruction at universities change to a better balance between in-person and remote instruction; students can time-shift lectures, interact with their instructors via chat, and collaborate with other students at a distance for some portion of the time. This will involve significant changes to the economic models of universities that have invested heavily in on-campus housing (e.g., perhaps alternate semesters of in-person and remote); over time, this could significantly lower the cost of college education. I believe that education for younger students should involve more remote learning, too. My niece is taking high-school chemistry this summer; the remote learning model worked far better for her than an in-person model would have, as she benefited enormously from the opportunity to move at her own rate, to re-work homework multiple times, and so forth. Hybrid models of education that blend in-person and remote learning are likely to be superior to today's all-in-person models, with their built-in expectations that every student can learn at the same rate.
