When to Commute During the COVID-19 Pandemic and Beyond: Analysis of Traffic Crashes in Washington, D.C
(2024-11-08) Choi, Joanne; Clark, Sam; Jaiswal, Ranjan; Kirk, Peter; Jayaraman, Sachin; Ashqar, Huthaifa
Many workers in cities across the world, who have been teleworking because of the COVID-19 pandemic, are expected to be back to their commutes. As this process is believed to be gradual and telecommuting is likely to remain an option for many workers, hybrid model and flexible schedules might become the norm in the future. This variable work schedules allows employees to commute outside of traditional rush hours. Moreover, many studies showed that commuters might be skeptical of using trains, buses, and carpools and could turn to personal vehicles to get to work, which might increase congestion and crashes in the roads. This study attempts to provide information on the safest time to commute to Washington, DC area analyzing historical traffic crash data before the COVID-19 pandemic. It also aims to advance our understanding of traffic crashes and other relating factors such as weather in the Washington, DC area. We created a model to predict crashes by time of the day, using a negative binomial regression after rejecting a Poisson regression, and additionally explored the validity of a Random Forest regression. Our main consideration for an eventual application of this study is to reduce crashes in Washington DC, using this tool that provides people with better options on when to commute and when to telework, if available. The study also provides policymakers and researchers with real-world insights that decrease the number of traffic crashes to help achieve the goals of The Vision Zero Initiative adopted by the district.

DETECTING ADS-B REPLAY CYBERATTACKS IN THE NATIONAL AIRSPACE SYSTEM
(International Association for Computer Information Systems, 2023) Ray, George; Ray, Jeffrey
This paper investigates the cybersecurity risks in the National Airspace System (NAS) with the introduction of Automated Dependent Surveillance Broadcast (ADS-B) equipment, which has been required for regulated airspace since 2020 and will be essential part of the Next Generation (NextGen) Air Transportation System (ATS) infrastructure. It details the national security implications of the cybersecurity vulnerabilities in the ADS-B avionic system and reviews proposed mitigations. One of the possible attacks on ADS-B is the replay attack and the authors propose and test a method to detect such an attack using cosine similarity. To validate the approach, the authors developed a computer-based ADSB system using an RTL-Software Defined Radio (SDR) receiver to capture over 14 million live ADS-B transmissions from a region northwest of the Dulles International Airport. These readings were organized into a relational database for analysis. A data-driven detection algorithm was implemented with parallelism through shared memory and a live feed of ADS-B traffic interspersed with previously recorded message-sets as replay attacks. The system successfully detected various replay attack scenarios. Suggested mitigation measures for countering replay attacks are presented.

Security implications in the transformation of healthcare through internet of things devices
(International Association for Computer Information Systems, 2021) Ray, George; Ruhode, Ephais; Mubako, Albert; Ray, Jeffrey; Kashiri, Walter
Africa has a growing industry producing medical devices for the developing world that are ASSURED: Affordable, Sensitive, Specific, User-friendly, Rapid, Equipment-free and Deliverable to end-users. This industry and more generally healthcare in Africa benefits by adding security to ASSURED. This paper investigates two questions related to security for IoT medical solutions: 1.) What are the vulnerable security points in an IoT based medical system; and 2.) How can these vulnerabilities be hardened? To answer these questions, a security reference architecture is identified that can be the framework for identifying, understanding, teaching and mitigating threats in the various modules of an IoT healthcare solution.

Post- Crisis Leadership: How Leaders can Embrace Chaos
(Forex Press, 2020-12-04) Robinson, Denean
Post-crisis leadership is a proactive approach where leaders must survey the internal and external environments to garner the trend of consumers buying behaviors. During this time, data analytics, re-energizing of sales and selecting a leadership style is crucial in beating your industry competitors. By reading this article, it will give leaders a new look on how to create marketing, and employee development strategies in defining their organizations. Strategic and tactical planning are key concepts needed to create internal activities for immediate implementation. Employees and leaders must work together to create a win-win situation for the consumer during these unprecedented times. This article will discuss several main theories. Those theories include: Customer Relationship Management, Four Functions of Management and Servant Leadership. In a post-crisis pandemic, leaders must learn how to plan, organize, lead and control. The planning phase leads managers to develop an overall strategy by selecting goals, allocating resources and determining success rates of the plans to improve the overall strategy of the organization. During the second phase, organizing determines the organizational structure for executing the plans, assigns authorities, defines resource allocations and details how well tasks will be organized. In the third phase, leading will identify those who will head the plan and manage all tasks during implementation. Controlling is the last phase where continuous monitoring occurs surrounding goals completions and interventions. Customer Relationship Management and Servant Leadership focus on strengthening relationships with your customers to determine what are the next steps in satisfying their buying behaviors. Leaders have to help customers get as much value from the product or service as they can. Organizations have to develop a meaningful partnership so the customer can generate revenue. Finally, leaders have to be proactive, develop long-term relationship bonding, demonstrate product/service value, and generate revenue.
Asynchronous Transfer Mode (ATM) Technology and Applications
Ray, Jeffrey
The purpose of this paper is to summarize the Asynchronous Transfer Mode (ATM) technology and determine where it is in its evolutionary development. Technologies that fragment data into small pieces typically have very poor performance because there is no mechanism to detect and retransmit lost cells when a piece of the data is lost in transit. The only way to recover the damaged cell is to retransmit the entire large packet again. An alternative to inefficiently retransmitting the entire packet is to only retransmit the individual cells that are lost or damaged. The ATM technology incorporates the ability to retransmit only the cells in each packet that were not received properly. It also enhances transmission performance by reducing flow control activity required at each network link. Surveying recent products serves as an effective barometer for determining how the ATM technology is evolving. State-of-the-market ATM products indicate that an ATM design solution provides unmatched speed, fault-tolerance, and scalability through multiple, meshed inter-switch connections that support load-sharing across networks. At its current point in evolutionary technological development, ATM is a key enabling communications technology that will introduce new applications to users and network providers, as well as provide higher bandwidth capacity to networks. Because of its high-bandwidth capacity and cell-oriented architecture, ATM is the dominant infrastructure for delivering virtually all types of communications, including data, voice, image, and multimedia, into the buildings and desktops of users around the world. By carefully considering critical performance issues, and accommodating existing legacy systems during ATM implementations, the telecommunications industry has insured that ATM will not only be the design solution of the future, but that it can provide cost effective applications today as well.
The Economic Man
(2012-04-15) Ray, Jeffrey
This paper questions how economic systems are using knowledge to support economic decision making. Scientific knowledge collected by centralized planners is not the right type of information to base economic decisions on since it does not have the capacity to consider local opportunity factors. These concerns, originally espoused by Frederick Hayek when analyzing the economy as a whole, can be decomposed to focus on individual businesses. A large corporation, encumbered with a traditional vertical organizational structure, typically has an executive management team taking on the role of the centralized planners in Hayek’s model, and is forced to make decisions without the local opportunity knowledge that may be available in their low-level business units. Economic decisions must fundamentally be based on accurate information that considers local opportunities, and must be made rapidly in today’s dynamic market place. To get access to local knowledge from their low-level business units, executive management teams should consider implementing learning organizations with horizontal management structures that encourage collaboration. Companies with centralized organizational structures simply move too slowly to be competitive. The “Economic Man” is an economist’s creation designed by Mr. Hayek to show how unlikely it is that economic decision makers could ever accurately predict future economic conditions. A hypothetical “Economic Man” with “perfect foresight” was described, in essence, to allow readers to visualize the futility of the assumptions underlying our current economic theories. Yet in today’s competitive business environment, perfect foresight is precisely the standard we impose on our executive managers. The perfect knowledge assumption is said to mislead these economic decision makers into a false believe the problem is simpler, from the perspective of the information needed to support such decisions, than it actually is. This results in poor investment decisions by managers that collect the wrong economic data. The division of labor concept notices that complex jobs can be more efficiently completed by a number of workers performing specialized tasks, than by one worker trying to complete the entire job. By dividing up the required skills on complex tasks across multiple workers, they can become specialists and work their assigned area more efficiently. The level of knowledge required to make workers skilled specialists is essential for the division of labor concept to be effective. Further knowledge is required to quantify economic input variables to the extent that decision makers in executive management can accurately predict how the marketplace will unfold and, in so doing, achieve an "economic man" like stature. No matter how we materialize or describe the problem; it seems the effective acquisition and use of knowledge is the correct answer. Peter Drucker relates the economic successes a corporation has with their ability to create “core competencies” that lead to market leadership positions. He begins to abstractly define the type of data that should be collected to help managers of these corporations monitor the strength and relative position of their core competencies. This relates to Mr. Hayek’s concern that managers need accurate, but relevant, information to base their decisions on. Just when things were looking bleak for our hypothetical “Economic Man,” these important steps define feasible types of real time information processing that can support economic decision makers monitoring the strength and position of core competencies. While it’s not quite as good as the perfect foresight imposed on our “Economic Man,” relevant, near real time economic data is a giant leap forward.
Knowledge and Knowledge Barriers
(2011-11-14) Ray, Jeffrey
This paper investigates spacial clustering of entrepreneurship and considers work advanced by David Andersson in the field. It assesses the influence that knowledge, in the form of insight, has on creating local economic opportunities, and relates how knowledge is used to advance the theory of spacial clustering to other economic models. A survey of how knowledge is used in some of our economic theories is performed to see if its use in the spacial clustering proposition is consistent. In reviewing how knowledge influenced the spacial nature of entrepreneurship, it was determined that alertness of local economic opportunities plays an essential role in determining successful economic endeavors and supports a core management construct that accurate information is fundamental for effective decision making. The review of how knowledge is used within many of our current economic theories is enlightening. Entrepreneurial knowledge with local time and space information incorporated was found more persuasive as a basis for investments than centralized technical knowledge. Alertness of profit opportunities was found to be the type of knowledge that will consistently reduce investment risks. Knowledge, in its many forms, is not necessarily reducible to entrepreneurial alertness, but rather, is merely a factor that helps explain when discoverable profit opportunities are available to entrepreneurs. Entrepreneurs must still have perfect foresight and overcome knowledge barriers. This paper concludes that spacial clustering of entrepreneurial innovation, despite the introduction of new networking technologies that facilitate near-universal distribution of information, is an appropriate economic model that takes into account the face-to-face nature necessary for maintaining entrepreneurial alertness.
Combining Measurement Frameworks
(2011-12-27) Ray, Jeffrey
This paper reviews and summarizes financial measurement systems and evaluates them against some core management constructs. First, accurate information is fundamental for decision making. Recent improvements in financial control systems and processes offer improvements in the accuracy of the cost and profit data being reported to management. Techniques such as Activity Based Costing (ABC), the Balanced Scorecard, and the Economic Value Added (EVA) concept have improved the accuracy of financial data and given companies that implement them a competitive advantage. Second, the EVA approach can be used to account for the total cost of the capital employed to generate revenues, and provides a metric for measuring the economic value added by corporate operations. Shareholders and the investment community are pressuring managers to deliver value and are demanding more accurate and transparent performance measurement approaches. Combining new and improved performance measurement frameworks may provide synergies that provide even more benefits. The ABC, Balanced Scorecard and EVA techniques are reviewed and evaluated for compatibility to see if they could be used simultaneously in combination, or whether they are mutually exclusive of each other. An analysis of the benefits provided by each technique is persuasive. ABC is a superior method of allocating overhead and indirect costs to products and services so a more accurate evaluation of their profitability can be made. The Balanced Scorecard enables managers to identify and track a number of financial and non-financial metrics to provide an accurate view of operating performance. EVA is an “economic” metric for measuring corporate performance that takes into account the cost of equity on assets employed and helps managers report out accurate valuations of economic profit. Since each technique involves improving the accuracy of information provided to economic decision makers, and can be tailored to a particular project’s critical success factors, the three techniques were found to be complimentary and can be used in combination.
Karl Popper and the Call for Academic Discipline
(2011-10-29) Ray, Jeffrey
Karl Popper was a philosopher that criticized traditional views of how knowledge was purported to support scientific and philosophical hypotheses. This paper analyzes the influence Popper had on how knowledge is used to support science. With respect to the formation of theories, the traditional view is observations are the basis of hypotheses that form rules that can be extended past the observations and original experimental constraints and assumptions. This approach causes several problems. The problem of demarcation concerns our inability to draw the line between statements of science and those that are pseudo-scientific, or religious in nature. There is no clear point where science ends and conjecture starts, so how do we know how much reverence to give particular theories? The problem of induction asserts that universal laws are based on specific assumptions, but yet are extrapolated out through an induction process to cover circumstances not originally observed. The assumption that the law applies to new, unobserved circumstances is a risky one and must be supported by new assumptions not verified by the original observations. Researchers still view scientific hypotheses as theories that are proven out by observations during controlled experiments. Popper, however, flipped this view around and argued that any theory was simply a hypothesis that had not yet been disproved. Science is said to be a struggle between competing theories. Every imperfect theory is thought of as a representation of reality that became preeminent by surviving the scrutiny of scientists as they experiment and observe the real world. Rigorous testing eliminates weaker theories, leaving the strong theories to survive. The longer theories survive, the more they are scrutinized and refined to accommodate new findings. Thus, researchers submit their hypothesis to severe testing to expose any flaws in the underlying theory. Although ideas certainly flow from observations, Popper makes a convincing argument that the observations can never be a basis for validating theories due to the problems of demarcation and induction. After some analysis, this paper adopts his contention that a theory cannot be verified through testing, but rather, the test results merely indicate that a theory has not been dis-proven and should be provisionally retained as the best available theory until it is eventually falsified.
Economics, Positive Science and the Quest for Predictive Performance
(2011-05-12) Ray, Jeffrey
This paper tracks the evolution of the subject area of positive economics from the contributions of John Keynes, Friedrich Hayek, Milton Friedman, and Karl Popper. Economics is said to be a “positive science” that can be used to predict the consequences of “changes in circumstances.” Like other scientists, economists need to be self-conscious about their research methodology. Keynes, Friedman and Hayek all attacked the problem of applying scientific methodology to economics from different perspectives. Although in some aspects their results were similar, some key distinctions often contrasted their teachings. This paper addresses these distinctions and concludes that a researcher’s perspective, as they develop and test economic theories, is influenced by the view of how they expect to implement the theories. An advocate for one theory, therefore, may observe the same experiment and come to completely different conclusions than an advocate of another theory observing the same experiment. When viewed as a body of a substantive hypothesis, a theory is found to have a predictive power. Only factual evidence can prove the theory right or wrong. The only relevant test of validity of a hypothesis is to compare its predictions with experience. Scientific theories must be prohibitive in that they forbid by implication particular findings. As such, a theory can be tested and falsified, but never logically verified. The distinction Popper made is it’s not appropriate to infer that a theory can be verified through testing. But rather, test results merely indicate that a theory wasn't proven wrong and, as such, should be provisionally retained as the best available theory until it is finally discredited, or is superseded by a better theory. Since economics is said to be a science that is denied dramatic and direct evidence from conclusive experiments, the fact that theories can never be verified is particularly troublesome. It makes it hard to achieve a consensus for economic theories which tend to require economic metrics collected over time to support them. This renders the weeding-out of unsuccessful hypotheses slow and difficult. While economics may be a positive science, this paper contends it has inherent barriers caused by a scientific methodology that anticipates development of hypotheses that can predict future states, and be verified by controlled observations. The economy is a complex mechanism not suited to abstracting out aspects of the problem to support a focused investigation of potential remedies.
Planning the Research Dissertation Project
Ray, Jeffrey
This paper examines what a dissertation is, summarizes some best practices for preparing one, and then describes a detailed action plan that can be used to manage the entire research effort.
Recognizing Project Management as an Abstract Science
(2012-05-12) Ray, Jeffrey
Researchers indicate a shift in scholarly focus from a systems perspective, to one of leadership and organizational behavior. To address increasing project failure rates, leadership theories are being implemented to improve project performance by improving organizational cultures. The practice of Project Management, however, does not offer a framework for developing theories to improve project success rates, and then tracking them to prove their validity. This paper suggests that project management is really an abstract science and practitioners should act like scientists and develop project success theories. It concludes by assessing central research paradigms tailored for project management.
Defining Organizational Culture for Entrepreneurs
(2011-07-24) Ray, Jeffrey
It appears that innovation, and how an organization can acquire it, is the key to being competitive in the New Product Development (NPD) marketplace. Knowledge that leads to innovation in products, unlike specialized scientific knowledge areas (for which there are designated labor markets to exploit the needed skills), is not home grown, is not the focus of any curriculums in our educational institutions, and is not associated with our typical project management processes. An organization must make a deliberate, on-going effort to develop innovation. If organizations can capture lessons learn from NPD experiences, and develop the characteristics that make the NPD projects successful, then the whole organization will have a better competitive posture. Organizations must have senior management that set clear goals and encourage employees to participate in the decision making to be successful on NPD projects. Since all decisions in traditional organizations are made by managers without the input of their employees, it becomes evident why traditional management approaches are not successful on NPD projects, which must be a collaborative effort. To encourage organizational innovation, NPD project success factors such as maintaining effective supplier relationships, tracking the location and capabilities of innovation clusters, maintaining collaboration between marketing and engineering teams, and implementing a progressive organizational structure, should be implemented.
