to think critically means that we are able to think in a logical fashion — in straight lines, as it were. One of the hardest skills that all undergraduates have to acquire is being able to think logically and then formulate these logical thoughts into sentences to produce an academic essay. Sentences and paragraphs in an essay have to follow on from each other in a logical sequence. This is part of critical thinking. So titles like Practical Logic or Reasoning (...) reflect this aspect of critical thinking. (shrink)

This paper explores the transformation of Twitter from the traditional developer based command and control into something strangely democratic: a social construction of utility, a twisting of this once unique service to serve the needs and desires, ever evolving, of its users. We explore changes in the social constructions of Twitter and use recent research in the Philosophy of Data to suggest potential explanations.

The possible future use of lethal autonomous weapons systems (LAWS) and the challenges associated with assigning moral responsibility leads to several debates. Some authors argue that the highly autonomous capability of such systems may lead to a so-called responsibility gap in situations where LAWS cause serious violations of international humanitarian law. One proposed solution is the doctrine of command responsibility. Despite the doctrine’s original development to govern human interactions on the battlefield, it is worth considering whether the doctrine of (...) command responsibility could provide a solution by applying the notion analogously to LAWS. A fundamental condition underpinning the doctrine’s application is the control requirement, stipulating that a superior must exert some degree of control over subordinates. The aim of this article is to provide an in-depth analysis of this control condition and assess whether it leads to the impossibility of applying the doctrine of command responsibility to LAWS. To this end, the first section briefly introduces the topic of LAWS and responsibility gaps. The subsequent section provides a concise overview of the doctrine itself and the conditions typically necessitated for its application. In the third section, a comprehensive scrutiny of the control requirement is undertaken through examination of key case law, examining how the concept has been interpreted. Finally, the fourth section delves into the evaluation of commanders’ potential to exert effective control over their (non-human) subordinates. Based on this, the feasibility of considering command responsibility as a viable solution is assessed, aiming to determine whether its application should be prima facie excluded or warrants further exploration.

This abstract presents a novel brain-computer interface (BCI) framework to control a prosthetic leg, for the rehabilitation of patients suffering from locomotive disorders, using functional near-infrared spectroscopy (fNIRS). fNIRS signals corresponding to walking intention and rest are used to initiate and stop the gait cycle and a nonlinear proportional derivative computed torque controller (PD-CTC) with gravity compensation is used to control torques of hip and knee joints for minimization of position error. The brain signals of walking intention and (...) rest tasks are acquired from primary motor cortex in the left hemisphere for nine subjects. After acquiring brain signals, in order to remove motion artifacts and physiological noises, the performance of six different filters i.e. Kalman, Wiener, Gaussian, hemodynamic response filter (hrf), Band-pass and finite impulse response, is evaluated. Afterwards, six different features are extracted from oxygenated hemoglobin signals and their different combinations were used for classification. The classification performance of five different classifiers i.e. artificial neural network, quadratic discriminant analysis, linear discriminant analysis (LDA), Naïve Bayes and support vector machine (SVM) is used. The classification accuracies obtained from SVM using hrf filter are significantly higher (p < 0.005) than the other combinations of classifier and filters. These accuracies are 77.5%, 72.5%, 68.3%, 74.2%, 73.3%, 80.8%, 65%, 76.7%, and 86.7% for all nine subjects. The control commands generated using classifier initiate and stop the gait cycle of the prosthetic leg whose knee and hip torques are controlled using PD-CTC to minimize position error. The proposed scheme can be effectively used for neurofeedback training and rehabilitation of lower limb amputation of paralyzed patients. (shrink)

Future weapons will make life-or-death decisions without a human in the loop. When such weapons inflict unwarranted harm, no one appears to be responsible. There seems to be a responsibility gap. I first reconstruct the argument for such responsibility gaps to then argue that this argument is not sound. The argument assumes that commanders have no control over whether autonomous weapons inflict harm. I argue against this assumption. Although this investigation concerns a specific case of autonomous weapons systems, I (...) take steps towards vindicating the more general idea that superiors can be morally responsible in virtue of being in command.

The link between seen and unseen, matter and spirit, flesh and soul was always presumed, but never clarified enough, leaving room for debates and mostly controversies between the scientific domains and theologies of a different type; how could God, who is immaterial, have created the material world? Therefore, the logic of obtaining a result on this concern is first to see how religions have always seen the ratio between divinity and matter/universe. In this part, the idea of a world personality (...) is implied by many, so that nature itself was transformed into a person ; others have seen within the universe/the world a Spirit ruling all, connecting all and bending all to God’s commands. In a way or another, every culture has gifted the universe/nature with the capability of ruling all, seeing everything and controlling, even determining facts by connecting all together with a Great Spirit. What is this Great Spirit of all and where it resides? With the analogy of human body in relation to his Spirit we will try to figure out a place or vehicle for the Spirit to dwell the body, and the Great Spirit the matter. The Christianity names this linkage between God and matter as ‘the created grace of God’, which indwells matter and helps the Creator move and transform things. Is there any scientific argument to sustain such assertion? Can we argue somehow that God’s voice makes matter vibrate from within the way it can recombine primer elements into giant stars to the human body? If so, what should be the ratio between theology and science on this issue and with these assertions? How could God command to matter to bring things and beings out of it and what were the material leverages that was supposed to be operated to accomplish His will? However, if we can assume that God resides in the universe – as a whole, His body, or as in its very fabric – can we also figure out how is this even possible, without transforming our explanation into a pantheistic and immanent exclusive one? Through these ‘divine leverages within matter’ theory, there is no need for questioning evolutionism, creationism, pantheism, deism and many other cosmological hypotheses any longer. (shrink)

Military reproductive health policies affect large numbers of women. In 2006 servicewomen numbered nearly 350,000 and comprised 14.5% of active-duty forces and 17.4% of the reserve force. In addition, approximately 165,000 female dependents of active duty military personnel and 157,000 female dependents of reserve duty personnel are between the ages of 12 and 22 and are eligible for military health care services. Dependents of military personnel are eligible for military health care coverage until age 21, or up to the age (...) of 23 if considered a full-time student.About 10% of active duty female servicemembers become pregnant each year. Pregnant servicewomen are considered non-deployable and are usually not assigned to overseas commands. Pregnant women in the Army, the service branch with the greatest number of women on active duty, can choose to remain on active duty, request temporary leave from service, or request separation from service. Separation options include either discharge, honorable or uncharacterized depending on rank, or transfer to individual ready reserve. (shrink)

Over recent years, brain-computer interface (BCI) has emerged as an alternative communication system between the human brain and an output device. Deciphered intents, after detecting electrical signals from the human scalp, are translated into control commands used to operate external devices, computer displays and virtual objects in the real-time. BCI provides an augmentative communication by creating a muscle-free channel between the brain and the output devices, primarily for subjects having neuromotor disorders, or trauma to nervous system, notably spinal cord (...) injuries (SCI), and subjects with unaffected sensorimotor functions but disarticulated or amputated residual limbs. This review identifies the potentials of electroencephalography (EEG) based BCI applications for locomotion and mobility rehabilitation. Patients could benefit from its advancements such as wearable lower-limb (LL) exoskeletons, orthosis, prosthesis, wheelchairs, and assistive-robot devices. The EEG communication signals employed by the aforementioned applications that also provide feasibility for future development in the field are sensorimotor rhythms (SMR), event-related potentials (ERP) and visual evoked potentials (VEP). The review is an effort to progress the development of user’s mental task related to LL for BCI reliability and confidence measures. As a novel contribution, the reviewed BCI control paradigms for wearable LL and assistive-robots are presented by a general control framework fitting in hierarchical layers. It reflects informatic interactions, between the user, the BCI operator, the shared controller, the robotic device and the environment. Each sub layer of the BCI operator is discussed in detail, highlighting the feature extraction, classification and execution methods employed by the various systems. All applications’ key features and their interaction with the environment are reviewed for the EEG-based activity mode recognition, and presented in form of a table. It is suggested to structure EEG-BCI controlled LL assistive devices within the presented framework, for future generation of intent-basedmultifunctional controllers. Despite the development of controllers, for BCI-based wearable or assistive devices that can seamlessly integrate user intent, practical challenges associated with such systems exist and have been discerned, which can be constructive for future developments in the field.

Utilization of renewable energies in association with energy storage is increased in different applications such as electrical vehicles, electric boats, and smart grids. A robust controller strategy plays a significant role to optimally utilize the energy resources available in a power system. In this paper, a suitable controller for the energy resources of an EB which consists of a 5 kW solar power plant, 5 kW fuel cell, and 2 kW battery package is designed based on the linear parameter varying (...) controller design approach. Initially, all component dynamics are augmented, and by exploiting the sector-nonlinearity approach, the LPV representation is derived. Then, the LPV control method determines the suitable gains of the states’ feedbacks to provide the required pulse commands of the boost converters of the energy resources to regulate the DC-link voltage and supply the power of EB loads. Comparing with the state-of-the-art nonlinear control methods, the developed control approach assures the stability of the overall system, as it considers all component dynamics in the design procedure. The real-time simulation results demonstrate the performance of the designed controller in the creation of a constant DC-link voltage. (shrink)

This paper suggests an online solution for the optimal tracking control of robotic systems based on a single critic neural network -based reinforcement learning method. To this end, we rewrite the robotic system model as a state-space form, which will facilitate the realization of optimal tracking control synthesis. To maintain the tracking response, a steady-state control is designed, and then an adaptive optimal tracking control is used to ensure that the tracking error can achieve convergence in (...) an optimal sense. To solve the obtained optimal control via the framework of adaptive dynamic programming, the command trajectory to be tracked and the modified tracking Hamilton-Jacobi-Bellman are all formulated. An online RL algorithm is the developed to address the HJB equation using a critic NN with online learning algorithm. Simulation results are given to verify the effectiveness of the proposed method.

Extant studies on stakeholder engagement have noted the inherent tensions arising from participation efforts, giving rise to the dark side of engagement. However, few studies have focused on organizational power relations that provide specific conditions for engagement and the related paradox that control represents. Drawing on strategy discourse and paradox as theoretical lenses, we examine engagement as a nexus of observed societal expectations, subjectivities provided by the strategy discourse, and the subject positions adopted by the individuals, giving rise to (...) a contradiction between openness and control. As a result, we present three modes of participation: inclusion, admittance, and quasi-participation. We contribute to stakeholder engagement and paradox literature by outlining the “engagement-control paradox” and showing how the prevailing strategy discourse may drive the use of participation as a form of control. Maintaining different modes of participation introduces inadvertent closure for participation and hinders strategy-making and the development of the organization. (shrink)

As frequent, violent, and organized peasant protests show, China’s reform regime has lost its once all-powerful control in the countryside. The sharp decline of village cadres’ positional authority in allocating economic resources, which began in post-Mao decollectivization, holds the key to explaining the change. Since the late 1990s, the collapse of village enterprises and the erosion of power over land have cost village cadres their remaining economic levers to engage the villagers as well as their incentives to work for (...) the party-state. The loss of the regime’s grip on village cadres and the loss of command by village cadres on peasants have almost synchronized, causing the traditional structure of organizational control to crumble in vast rural areas. In the new, prevailing patterns of village governance, party power is becoming increasingly irrelevant. (shrink)

The lambda model predicts that the command received by each motor nucleus during locomotion is specific for the joint at which its muscle acts and is independent of external conditions. However, investigation of the commands received by motor nuclei during fictive locomotion and of the sensitivity of these commands to feedback from the limb during locomotion indicates that neither condition is satisfied.

This dissertation examines Aquinas's teaching on the acts specific to temperance. According to a widespread interpretation of this teaching , the proper act of temperance is spontaneous, ordinate passion. Temperance thus not only causes someone to experience the right passions towards the right objects but does so antecedent to reason's command. Indeed, temperance is thought to have little if anything to do with reason's control of the passions. In an introductory chapter, I show that this understanding of temperance (...) faces a number of serious objections. In the next four chapters, I develop the thesis that the proper act of temperance is ordinate, consequent passion alone; the only relation temperance has to antecedent passion is simply to prevent it from ever being vehement, affecting only its intensity, not its ordination. ;I develop my thesis by examining Aquinas's teaching on the passions, which can only be consistently ordinate if commanded by reason ; reason's control of the passions, which can be consistent only if the sense appetite is habituated to obey reason alone, thus preventing it from being moved by any of the external or internal sense powers when they move antecedent to reason's command ; habit, which is not a principle of spontaneous action or passion, but is rather something we use only when we will . Temperance is thus a habit that gives reason nearly complete control of the passions, a moral virtue that is used only when we will and thus is exclusively a cause of ordinate, consequent passion . ;In the final chapter, observing that Aquinas is silent on the consistency with which the temperate person experiences spontaneous, ordinate passions, I attempt to fill this lacuna by developing the notions of "semi-virtue" and "semi-virtuous passion," building on Aquinas's teaching on the internal sense powers, especially the cogitative power.

Autonomous underwater vehicles are widely used to accomplish various missions in the complex marine environment; the design of a control system for AUVs is particularly difficult due to the high nonlinearity, variations in hydrodynamic coefficients, and external force from ocean currents. In this paper, we propose a controller based on deep reinforcement learning in a simulation environment for studying the control performance of the vectored thruster AUV. RL is an important method of artificial intelligence that can learn behavior (...) through trial-and-error interactions with the environment, so it does not need to provide an accurate AUV control model that is very hard to establish. The proposed RL algorithm only uses the information that can be measured by sensors inside the AUVs as the input parameters, and the outputs of the designed controller are the continuous control actions, which are the commands that are set to the vectored thruster. Moreover, a reward function is developed for deep RL controller considering different factors which actually affect the control accuracy of AUV navigation control. To confirm the algorithm’s effectiveness, a series of simulations are carried out in the designed simulation environment, which is a method to save time and improve efficiency. Simulation results prove the feasibility of the deep RL algorithm applied to the control system for AUV. Furthermore, our work also provides an optional method for robot control problems to deal with improving technology requirements and complicated application environments. (shrink)

The application study of robot control based brain-computer interface not only helps to promote the practicality of BCI but also helps to promote the advancement of robot technology, which is of great significance. Among the many obstacles, the importability of the stimulator brings much inconvenience to the robot control task. In this study, augmented reality technology was employed as the visual stimulator of steady-state visual evoked potential -BCI and the robot walking experiment in the maze was designed to (...) testify the applicability of the AR-BCI system. The online experiment was designed to complete the robot maze walking task and the robot walking commands were sent out by BCI system, in which human intentions were decoded by Filter Bank Canonical Correlation Analysis algorithm. The results showed that all the 12 subjects could complete the robot walking task in the maze, which verified the feasibility of the AR-SSVEP-NAO system. This study provided an application demonstration for the robot control base on brain–computer interface, and further provided a new method for the future portable BCI system. (shrink)

The following questions are discussed: (1) Who determines the nature of “control variables”? (2) Is the “positional monopoly” healthy? (3) Does a descending command alter reflex threshold alone without eoncomitantly altering stiffness? (4) How does the CNS deal with history-dependent effects? (5) Should we abandon the idea that the CNS controls classical Newtonian variables such as muscle length?

The extensive involvement of nonconscious processes in human behaviour has led some to suggest that consciousness is much less important for the control of action than we might think. In this article I push against this trend, developing an understanding of conscious control that is sensitive to our best models of overt action control. Further, I assess the cogency of various zombie challenges—challenges that seek to demote the importance of conscious control for human agency. I argue (...) that though nonconscious contributions to action control are evidently robust, these challenges are overblown. (shrink)

Theories of ethics that attempt to incorporate divine speech or commands as necessary elements in the construction of moral obligations are often viewed as vulnerable to a challenge based on the so-called Euthyphro dilemma. According to this challenge, opponents of theistic ethics suppose that divine speech either informs one of a preexisting set of values and obligations, which makes it inconsequential, or is entirely arbitrary, which makes it irrational. This essay analyzes some of the debates on the nature of divine (...) commands in eleventh-century works of Islamic jurisprudence. I show that Muʿtazilī jurisprudents advanced the view that divine commands were actions performed in time that had concrete manifestations, while Ashʿarīs argued that divine speech in general, and commands in particular, were eternal divine attributes. After exposing certain weaknesses in the Euthyphro-inspired objections to theistic ethics, I argue that the Ashʿarī idea of commands as divine attributes is a promising move for scholars interested in defending a divine command view of moral obligation.

This essay presents a version of divine command metaethics inspired by recent work of Donnellan, Kripke, and Putnam on the relation between necessity and conceptual analysis. What we can discover a priori, by conceptual analysis, about the nature of ethical wrongness is that wrongness is the property of actions that best fills a certain role. What property that is cannot be discovered by conceptual analysis. But I suggest that theists should claim it is the property of being contrary to (...) the commands of a loving God. This claim, if true, is a necessary but not an a priori truth. It also is a claim, not about the way in which some believers use the word 'wrong,' but about the wrongness that virtually everyone talks about. This position is distinguished from the author's previous views, and from a holistic development of the latter proposed by Jeffrey Stout. (shrink)

This paper discusses the idea that the concept of privacy should be understood in terms of control. Three different attempts to spell out this idea will be critically discussed. The conclusion will be that the Source Control View on privacy is the most promising version of the idea that privacy is to be understood in terms of control.

Recent divine command theorists make a serious and impressive case that a sophisticated divine command theory has significant metaethical advantages and can adequately meet traditional objections, such as the Euthyphro problem. I survey the attempt sympathetically with a view to explaining how the divine command theory can deal with traditional objections while delivering on metaethical desiderata, such as providing an account of ethical objectivity. I argue, however, that to the extent that a divine command theory succeeds, (...) an ideal observer theory can do equally well. Once the divine command theory is rendered immune to Euthyphro-related objections, we will have all the machinery needed to show that an ideal observer theory can provide the same metaethical advantages, without supposing the existence of a divine commander. Other things being equal, ontological simplicity favors the ideal observer theory. (shrink)
