This study uses an artificial neural network model to forecast quarterly accounting earnings for a sample of 296 corporations trading on the New York stock exchange. The resulting forecast errors are shown to be significantly larger (smaller) than those generated by the parsimonious Brown-Rozeff and Griffin-Watts (Foster) linear time series models, bringing into question the potential usefulness of neural network models in forecasting quarterly accounting earnings. This study confirms the conjecture by Chatfield and Hill et al. that neural network models are context sensitive. In particular, this study shows that neural network models are not necessarily superior to linear time series models even when the data are financial, seasonal and non-linear. 相似文献

Most artificial intelligence technologies are dual-use. They are incorporated into both peaceful civilian applications and military weapons systems. Most of the existing codes of conduct and ethical principles on artificial intelligence address the former while largely ignoring the latter. But when these technologies are used to power systems specifically designed to cause harm, the question must be asked as to whether the ethics applied to military autonomous systems should also be taken into account for all artificial intelligence technologies susceptible of being used for those purposes. However, while a freeze in investigations is neither possible nor desirable, neither is the maintenance of the current status quo. Comparison between general-purpose ethical codes and military ones concludes that most ethical principles apply to human use of artificial intelligence systems as long as two characteristics are met: that the way algorithms work is understood and that humans retain enough control. In this way, human agency is fully preserved and moral responsibility is retained independently of the potential dual-use of artificial intelligence technology. 相似文献

With the discovery of the COVID-19 vaccine, what has always been worrying the decision-makers is related to the distribution management, the vaccination centers' location, and the inventory control of all types of vaccines. As the COVID-19 vaccine is highly demanded, planning for its fair distribution is a must. University is one of the most densely populated areas in a city, so it is critical to vaccinate university students so that the spread of this virus is curbed. As a result, in the present study, a new stochastic multi-objective, multi-period, and multi-commodity simulation-optimization model has been developed for the COVID-19 vaccine's production, distribution, location, allocation, and inventory control decisions. In this study, the proposed supply chain network includes four echelons of manufacturers, hospitals, vaccination centers, and volunteer vaccine students. Vaccine manufacturers send the vaccines to the vaccination centers and hospitals after production. The students with a history of special diseases such as heart disease, corticosteroids, blood clots, etc. are vaccinated in hospitals because of accessing more medical care, and the rest of the students are vaccinated in the vaccination centers. Then, a system dynamic structure of the prevalence of COVID -19 in universities is developed and the vaccine demand is estimated using simulation, in which the demand enters the mathematical model as a given stochastic parameter. Thus, the model pursues some goals, namely, to minimize supply chain costs, maximize student desirability for vaccination, and maximize justice in vaccine distribution. To solve the proposed model, Variable Neighborhood Search (VNS) and Whale Optimization Algorithm (WOA) algorithms are used. In terms of novelties, the most important novelties in the simulation model are considering the virtual education and exerted quarantine effect on estimating the number of the vaccines. In terms of the mathematical model, one of the remarkable contributions is paying attention to social distancing while receiving the injection and the possibility of the injection during working and non-working hours, and regarding the novelties in the solution methodology, a new heuristic method based on a meta-heuristic algorithm called Modified WOA with VNS (MVWOA) is developed. In terms of the performance metrics and the CPU time, the MOWOA is discovered with a superior performance than other given algorithms. Moreover, regarding the data, a case study related to the COVID-19 pandemic period in Tehran/Iran is provided to validate the proposed algorithm. The outcomes indicate that with the demand increase, the costs increase sharply while the vaccination desirability for students decreases with a slight slope. 相似文献

This special issue offers a new perspective on decision-making in internet governance, bringing together theoretical contributions and empirical knowledge on authority and influence in underexplored policy settings, from the Congress of the United States to RightsCon, a leading summit on human rights in the digital era. The articles included here shed light on specific groups underrepresented in existing research (such as civil society groups, expert activists, technical community) and on the interactions between these groups and traditional, powerful actors such as governments and industry. These contributions raise new questions, such as: is agency possible without representation in the digital space? Who can represent? Are deficiencies in technology governance affecting the representation model of our political systems more broadly? How do representation and agency manifest themselves across time and space? 相似文献

The United States needs to reimagine the basic principles of its telecommunications and information policy to fit an emerging society in which networking and intelligence are embedded into an increasing number of everyday things which constantly monitor and measure our lives. This emerging environment is an always-on, ubiquitous, integrated system comprised of the Internet of Things, Big Data, Artificial Intelligence/Intelligent Systems and the Intercloud, which act together as a single system, referred to here as the “Embedded Infosphere” (EI). This development is driving the latest stage – the third – in the evolution of U.S. communications policy.Each of the components of the EI presents unique challenges, but the greater concern is all of them acting in concert. These developments bring into focus many topics that have been outside the traditional communications policy envelope, and exceed the portfolios of existing agencies and institutions. This article envisions a new “EI policy space,” grounded in established societal values, and built on the experience of the previous stages.There are appropriate policy responses to each of the challenges, but these responses need to be seen in a holistic perspective, as they are all interconnected. Many of the issues such as privacy, security, consumer protection, and data stewardship are common across several elements. The larger goal is to establish a framework for an integrated policy structure which can address unpredictable emergent conditions, while allowing markets to flourish without unduly burdensome regulations, restrictions or uncertainties.This articles suggests a high-level analytical framework of criteria against which proposed EI policies can be measured. While there may be no “perfect” policies, some may be better (or worse) than others. It also offers a political process designed to incorporate the concept of the EI into national policy thinking. This approach should be implemented through a series of steps and should provide flexibility for development. The initial step is a process by which the EI can be acknowledged, its development analyzed, and the national interests institutionalized. The U.S. Senate has already initiated this process with the pending “DIGIT” Act, designed to bring together the core federal stakeholders and open a policy discourse which will be expanded over time to other key stakeholders. This should lead to the development of a national EI strategy.Since the EI is progressively global, the article suggests how both the normative and regulatory dimensions can be approached in the global context. It raises the possibility of a restructured ICANN “Empowered Community” as a possible venue for developing policies and recommendations in this area. It notes that since global unanimity is unlikely, non-governmental regimes will likely develop to address the unresolved policy interstices. 相似文献

Many foresight researchers believe that quantitative simulations have a very restricted contribution in futures studies due to their simplicity and lack of creativity. While qualitative methods, taking advantage of the human cognitive system, have a great potential in addressing a wide range of problems in futures studies, this potential is mostly due to the human visual logic that can handle the task of imagining future scenarios much better than mathematical logic.On the other hand, computational methods benefit from the advantages of silicon-based systems namely speed, large memory, rapid networking, and communication. Hence, it would be extremely beneficial to come up with a solution that combines the positive sides of both qualitative and computational approaches. Cognitive artificial agents are computational units that make use of the human cognitive system. Their interaction with foresight and futures researchers can result in promising solutions for the problems addressed in futures studies. In addition, these agents can serve as a great source of inspiration for taking the first step towards vision based computers that can simulate humans’ imaginations of the future.This paper reviews some of the previous attempts in this field and finally sheds light on the main issues where methods in futures studies can play a key role in the future of Human Computer Interaction systems. Our suggested architecture for a future studies interactions-based system along with its justifications and specifications is provided in the form of a request for proposal. 相似文献
