    The issue of moral luck is one of the interesting and influential issues in contemporary philosophy of ethics. The main question of this discussion can be expressed as follows: Do matters that are beyond the authority and control of the moral agent affect his moral standing or the extent of his worthiness for moral praise or blame? The “Principle of Control” replies negatively to this question while “Moral Luck” gives a positive one. In the first encounter with the jurisprudential tradition after Shaykh Ansari, it seems that there are two stances in this regard. Through the analytic study of this jurisprudential tradition, the authors have strived to identify, review, and explain the views presented in this intellectual tradition. The emphasis of the jurists that an involuntary act is outside the scope of duty, at least apparently, is an emphasis of the Principle of Control; however, we will see that this principle derived from the principles of jurisprudence is different from the Principle of Control raised in contemporary philosophy of ethics. On the other hand, the views of some jurists in the discussion of tajarrī, and their jurisprudence and interpretation regarding some narrations supports the acceptance of moral luck. A comparison of the collection of prevalent views in the principles of jurisprudence of contemporary Twelver Shiites leads us to the conclusion that the stance of most of them is to accept moral luck along with a particular reading that is compatible with the Principle of Control.   Introduction The issue of moral luck that was raised at the end of the twentieth century by Thomas Nagel and Bernard Williams can also be pursued in Twelver Shiite principles of jurisprudence. The aims of the authors of this paper are to identify, review, and analyze the prevalent view or viewsamong contemporary Twelver Shiite jurists in dealing with the issue of moral luck. In the jurisprudential tradition after Shaykh Ansari, there is a stance that approves the Principle of Control. However, a point to note is that the jurists have a particular reading of this principle which is different from the prevalent reading in contemporary philosophy of ethics. Some of the stances of contemporary Twelver Shiite jurists also support the acceptance of moral luck. As a result, moral luck is situational and dispositional. In this paper, we will show that many of the contemporary jurists accept moral luck and the Principle of Control that is compatible with it. The principle of control in Twelver Shiite principles of jurisprudence Based on the existing literature in contemporary philosophy of ethics, the Principle of Control can be explained as follows: The Principle of Control 1: The moral agent can only be morally evaluated to the extent that moral evaluation is based on factors that are under his free will and control. In contemporary Twelver Shiite principles of jurisprudence, free will is considered a necessary condition for duties or moral judgments. It seems that this view approves of the Principle of Control; however, not precisely the Principle of Control 1. The principle that can be attributed to the jurists is as follows: The Principle of Control 2: The moral agent is only assessable for the performance of an action that is under his authority and control. Or if it is not under his authority and control, the agent himself has caused this lack of authority through a voluntary act. Moral luck in Twelver Shiite principles of jusrisprudence On the other hand, some jurists do not consider a person who is a mutajarrī (one who has performed an act that he thinks is a sin which is not actually a sin) to be deserving of punishment; in contrast to a sinner whereas the difference between the two is in something that is beyond their authority and control. Similarly, it is well-known among jurists that a marja[1] who has arrived at reality will receive twice the reward while one had not arrived would receive one, whereas reaching reality is not completely under his authority and control. Two marajiʿ may strive to the same extent; however, only one of them will arrive at the correct view. The third stance that some contemporary jurists have raised regarding the worthiness of reward or punishment due to an involuntary action is their interpretation of narrations that state: The reward of someone who establishes a good tradition increases to the extent of adherence to that tradition and the punishment of someone who establishes a bad tradition increases to the extent of adherence to that tradition. Obviously, the extent of adherence to a tradition is not completely under the control of the founder of that tradition and two founders may strive to exactly the same extent to promote their traditions; however, one tradition will have more followers. Discussion The view of this group of jurists in these discussions requires that something outside the control and authority of the agent influences his worthiness of reward or punishment and this is equivalent to the acceptance of moral luck. Considering the differences between the Principle of Control 1 and 2, it seems that the Principle of Control 2 can be combined with moral luck and, as a result, with situational and dispositional moral luck. Based on the Principle of Control 2, for an agent to be properly evaluated, it is sufficient that his action is performed voluntarily, or if it is involuntary, the agent himself caused this involuntariness. However, based on the Principle of Control 1, the agent is only assessable to the extent that moral evaluation is based on factors that are under his authority and control. In reality, in the Principle of Control 2, only the voluntariness of an action is important and if the action itself is voluntary, the moral evaluation of the agent is not limited to the extent that the action is voluntary and under one’s control. Conclusion Some contemporary Twelver Shiite jurists believe that sometimes a matter beyond the authority and control of an agent is influential in the extent of the worthiness of praise and reward, or blame and punishment of an agent and, therefore, they accept moral luck; except causal luck. Similarly, the jurists also believe in a specific reading of the principle that is compatible with it

    Next Location Prediction Model: A Geohashed Based Recurrent Neural Network

    This work investigates the significance of choosing appropriate recurrent neural networks (RNNs) architecture for a spatiotemporal next location prediction framework. Dockless shared micro-mobility sharing programs provide spatial trajectory data that entails essential information for city planners and developers. The study compares (i) the variable-sized geohash tessellation and (ii) two common RNN architectures: Long Short-Term Memory (LSTM) and Gated Recurrent Units (GRU), using bike/scooter location data for Washington DC, USA. LSTM and GRU networks are used for modeling and incorporating information from spatial neighbors into the model. The study suggests that the LSTM model yields slightly better performance than the GRU model based on the same tessellation. However, geohash size might play a significant role in model performance. The study highlights the need to explore hyperparameter tuning, multiple spatial partitioning techniques especially with the Google S2 library, and more trip data for improving the prediction performance in neural network models

    Three Essays on Shared Micromobility

    No full text
    Shared micromobility defines as the shared use of light and low-speed vehicles such as bike and scooter in which users have short-term access on an as-needed basis. As shared micromobility, as one of the most viable and sustainable modes of transportation, has emerged in the U.S. over the last decade., understanding different aspects of these modes of transportation help decision-makers and stakeholders to have better insights into the problems related to these transportation options. Designing efficient and effective shared micromobility programs improves overall system performance, enhances accessibility, and is essential to increase ridership and benefit commuters. This dissertation aims to address three vital aspects of emerging shared micromobility transportation options with three essays that each contribute to the practice and literature of sustainable transportation. Chapter one of this dissertation investigates public opinion towards dockless bikes sharing using a mix of statistical and natural language processing methods. This study finds the underlying topics and the corresponding polarity in public discussion by analyzing tweets to give better insight into the emerging phenomenon across the U.S. Chapter two of this dissertation proposes a new framework for the micromobility network to improve accessibility and reduce operator costs. The framework focuses on highly centralized clubs (known as k-club) as virtual docking hubs. The study suggests an integer programming model and a heuristic approach as well as a cost-benefit analysis of the proposed model. Chapter three of this dissertation address the risk perception of bicycle and scooter riders’ risky behaviors. This study investigates twenty dangerous maneuvers and their corresponding frequency and severity from U.S. resident’s perspective. The resultant risk matrix and regression model provides a clear picture of the public risk perception associated with these two micromobility options. Overall, the research outcomes will provide decision-makers and stakeholders with scientific information, practical implications, and necessary tools that will enable them to offer better and sustainable micromobility services to their residents

    Future of Rural Transit

    Get PDF
    This paper provides a contemplative description of the future of rural public transportation. It considers emerging technologies along with their long-term implications and corresponding impacts on rural communities. The authors used their collective knowledge to identify key drivers of change in rural areas. As a result, the authors expect the future definition of rural areas to change and a new geographical classification to emerge. This classification is a continuum of population density gradient from highly populated urban areas to sparsely populated areas. The paper also suggests that automated vehicles and hologram telecommuting could dominate the U.S. transportation industry, even in rural settings

    Maximum Closeness Centrality k-Clubs: A Study of Dock-Less Bike Sharing

    No full text
    In this work, we investigate a new paradigm for dock-less bike sharing. Recently, it has become essential to accommodate connected and free-floating bicycles in modern bike-sharing operations. This change comes with an increase in the coordination cost, as bicycles are no longer checked in and out from bike-sharing stations that are fully equipped to handle the volume of requests; instead, bicycles can be checked in and out from virtually anywhere. In this paper, we propose a new framework for combining traditional bike stations with locations that can serve as free-floating bike-sharing stations. The framework we propose here focuses on identifying highly centralized k-clubs (i.e., connected subgraphs of restricted diameter). The restricted diameter reduces coordination costs as dock-less bicycles can only be found in specific locations. In addition, we use closeness centrality as this metric allows for quick access to dock-less bike sharing while, at the same time, optimizing the reach of service to bikers/customers. For the proposed problem, we first derive its computational complexity and show that it is NP-hard (by reduction from the 3-SATISFIABILITY problem), and then provide an integer programming formulation. Due to its computational complexity, the problem cannot be solved exactly in a large-scale setting, as is such of an urban area. Hence, we provide a greedy heuristic approach that is shown to run in reasonable computational time. We also provide the presentation and analysis of a case study in two cities of the state of North Dakota: Casselton and Fargo. Our work concludes with the cost-benefit analysis of both models (docked vs. dockless) to suggest the potential advantages of the proposed model
