In this paper, an active frequency control strategy of wind turbines based on model predictive control is proposed by using the power margin of wind turbines operating in load shedding mode. The frequency response model of the microgrid system with the load shedding of the wind turbines is used to predict the output power and system frequency deviation of the wind turbine. According to the prediction information, the output power control signal of the (...) model predictive controller in the wind turbine can be optimized. On this basis, a wind turbine active participation frequency control strategy based on model predictive control is designed by rolling prediction and optimization. The wind turbine power control signal after the strategy is used to adjust the output power of the wind turbine and balance the change of the active power of the system to reduce the frequency deviation.

The paper argues that it is a mistake to interpret Thomas Reid as holding a libertarian notion of freedom, and to make use of Reid to argue in support of a libertarian position. More precisely, this paper shows that Reid’s theory of agent-causation may not be what these philosophers take it to be, once such crucial notions as agent-causation and active power in Reid’s theory of free agency have been fully explicated. Reid is more committed to accepting the (...) view of freedom as rational self-control over the determination of the will than a contracausal view of freedom. (shrink)

This paper examines Aquinas’ account of a certain kind of rational control: the control one exercises in using one’s reason to make a judgment. Though this control is not itself a kind of voluntary control, it is a precondition for voluntariness. Aquinas claims that one’s voluntary actions must spring from judgments that are subject to one’s rational control and that, because of this, only rational animals can act voluntarily. This rational kind of control depends (...) on a certain distinctive feature of the rational faculty. For Aquinas, reason differs from other faculties in that it can be exercised in a peculiarly self-reflective way: in exercising reason one can be grasping the point of what one is doing in that very exercise of reason. The sense in which one controls one’s rational judgment is that one is, in judging, guided by the norm of judging truly. Aquinas holds that it is only possible to be so guided because the power by which one judges (namely, reason) is self-reflective in this special sense: part of what it is to judge is to grasp the point of what one is doing in that very act of judging. The paper argues that the roots of this view can be found in neoplatonic discussions of self-constitution and self-knowledge. (shrink)

There is a striking resemblance between the physical theory of Plato'sTimaeus and that of the Stoics; striking enough, indeed, to warrant the supposition that the latter was substantially influenced by the former. In attempting to trace the main lines of this influence, scholars have tended to focus attention almost exclusively on the Stoics' choice and characterization of the world's ultimate constituents: a rational principle that pervades and controls a material principle. In this paper, I offer some suggestions about how the (...) early Stoics may have reacted as readers to Plato's literary presentation of the dialogue's cosmogonic myth. On this basis I consider the proposal that the crucial philosophical appeal of the Timaeus for the Stoics – and perhaps the reason it attracted their interest in the first place – lay not in its claims about the Receptacle and World Soul, but rather in its portrayal of the Demiurge who designed the cosmos.

Prior to his renewed incumbency, as the fourth Prime Minister ofMalaysia, Mahathir Mohamad was able to remain in power for amore prolonged period compared to his predecessors. He was actively involvedin galvanizing political action immediately after the independence of Malaysiaand did not abandon active politics until his 2003 resignation. Under Mahathir’sleadership and guidance, Malaysia made remarkable economic and politicalprogress. He oversaw many innovations in the fledgling democracy and wasable to develop the country due to his exceptional leadership qualities. (...) His styleand attitude towards engaging with problems, particularly his stance during theAsian Monetary Crisis in 1997, was highly criticized by some, and labelled asdictatorial. This stigma did not detract him from the path he considered rightfor Malaysia, and under his leadership he garnered worldwide appreciation forhis national efforts and success in overcoming the economic crisis. Mahathiris undeniably an excellent case study as a prime minister, as well as a highly productive person. He contributed to a better understanding of modernMalaysia and his own tenure as PM in a series of books and articles. One ofthe significant aspects of his political heritage is his influential charisma andleadership. In all of his undertakings he has attracted both passionate supportand hatred from friends and foes, but his political footsteps have always beencertain and directed toward Malaysia’s national wellbeing. Mahathir is apolitician with sharp views on many issues and he was profoundly brave inverbalising them in the public arena, within Malaysia and internationally. Hisclear posture and speeches without fear made him a world-embracing politicalpersonality. This descriptive research study adopts a qualitative approach toanalyse historical information, documents, memoirs and articles, and books tobetter understand the leadership of Mahathir. (shrink)

It has been argued that the explanation of self-control requires positing special motivational powers. Some think that we need will-power as an irreducible mental faculty; others that we need to think of the active self as a dedicated and depletable pool of psychic energy or – in today more respectable terminology – mental resources; finally, there is the idea that self-control requires postulating a deep division between reason and passion – a deliberative and an emotional motivational (...) system. This essay argues that no such special motivational powers are necessary. Yet, at the same time, self-control does powerfully illustrate the importance of a feature of the mind. What it illustrates, I argue, is the importance of the mental activity of attention in the control of all action. It is by appeal to this mental activity that we can dispense with special motivational powers. If we think of Humeanism as the view that there is fundamentally only one kind of motivational system and that all action is based in that system, then this essay contributes to a defense of Humeanism. On the other hand, the essay also shows that any model of agency in terms of only beliefs and desires, motivational and representational states, or preferences and credences is incomplete. A different conception of Humeanism as the view that every mental state is either motivational, representational, or a combination of them, is false. (shrink)

With the development of distributed networks, the remote controllability of the distributed energy objects and the vulnerability of user-side information security protection measures make distributed energy objects extremely vulnerable to malicious control by attackers. Hence, the large-scale loads may produce abnormal operation performance, such as load casting/dropping synchronously or frequent and synchronous casting and dropping, and hence, it can threaten the security and stable operation of the distribution networks. First, we analyze the security threats faced by industrial controllable load, (...) civil controllable load, and the gains and losses of attacks on the distribution networks. Considering the factors of cyber attacks, we propose a control model and cyber attack model in active distribution networks. And, three types of attacks that the target suffered are defined on the basis of “on” and “off” modes for control. Then, the controllable load was maliciously controlled as the research object, and a suitable scenario is selected. The impact of malicious control of the controllable load on the power supply reliability and power quality of the distribution networks are simulated and analyzed, and risk consequences for different types of attacks are provided.

Manifest Activity presents and critically examines the model of human power, the will, our capacities for purposeful conduct, and the place of our agency in the natural world of one of the most important and traditionally under-appreciated philosophers of the 18th century: Thomas Reid. For Reid, contrary to the view of many of his predecessors, it is simply manifest that we are active with respect to our behaviours; it is manifest, he thinks, that our actions are not merely (...) remote products of forces that lie outside of our control. Reid holds, instead, that actions are all and only those events that spring from active power and he produces insightful and imaginative arguments for the claim that only a creature with a mind is capable of having active power. He believes that only human beings, and creatures 'above us', are capable of directing events towards ends, of endowing them with purpose or direction, the distinctive feature of action. However, he also holds that all events, and not merely human actions, are products of active power, power possessed either by human beings or by God. This collection of theses leads Reid to the view that human behaviour and the progress of nature are both essentially teleological. Patterns in nature are the products of laws of which God is the author; patterns in human conduct are the products of character and the laws that individuals set for themselves. Manifest Activity examines Reid's arguments for this view and the view's implications for the nature of character, motivation and the special kind of causation involved in the production of human behavior.

The article attempts to re-think active citizenship both from the point of view of social practice and scientific perspective and from the standpoint of modern social philosophy. It is shown that globalization is one of the most used terms of modern socio-humanitarian discourse but simultaneously one of the most difficult to define. Any research related to the global is also related to the national because the reception of global influences is different in different cultures. From the perspective of 2022, (...) the research shows a globalization crisis in the classical sense of the word. It is about the crisis of real and nominal political power, which are often incompatible with each other. In many countries, the desire for “strong statehood” is even stronger. It has been proven that the impact of globalization on society is actively mediated by civil society. In a philosophical sense, a developed civil society as a completed form of morally determined life is almost an ideal product of the history of civilization. The first trend of active citizenship transformation is economic liberalization. The second feature that determines changes in active citizenship is political pluralism. Active citizens control the basis of the activity of the modern state. In these conditions, the control function of the institution of citizenship becomes extremely important for the stable existence of political regimes and for achieving political stability. Another trend in the transformation of active citizenship is the growing role of the state in global processes. It was possible to distinguish two levels of transformation of active citizenship in the era of globalization. The first is interiorization, and the second is exteriorization. It has been proven that active citizenship is not only a social connection of people but also a way of existence characteristic of any civilized human community. (shrink)

To date researchers planning experiments have always lived by the mantra that 'using equal sample sizes gives the best results' and although unequal groups are also used in experimentation, it is not the preferred method of many and indeed actively discouraged in literature. However, during live study planning there are other considerations that we must take into account such as availability of study participants, statistical power and, indeed, the cost of the study. These can all make allocating equal sample (...) sizes difficult, and sometimes near impossible. This, some might say, means that the study would not adhere to rigorous statistical standard (Rosenbaum and Rubin, 1985). However, here we present evidence that, not only is this a false assumption, but that we may actually gain more power in the study by actually using unequal groups. Here, data from a Sepsis Biomarker study is used, in which the aim is to predict, by biomarker level and presence, whether the patient would go on to develop sepsis. It was found that larger control groups may give more power to studies looking for an effect in the mid range but not for large or small effects. This study shows merit in the hypothesis that more power can be achieved when a larger control group is used.

The power of routine and special observations: producing civility in a public acute psychiatric unit This study directly addresses controlling aspects of psychiatric nursing practice, which are currently marginalised in practice and research. We first consider the discursive tensions surrounding the mandated goal of social control in public acute psychiatric units, particularly referring to those units located within medical hospitals. We attest to the enduring social control mandate in psychiatric nursing and explore ways in which it is (...) enacted.Specific nursing practices of ‘doing the obs’ while scanning the ward and ‘special observations’ are investigated as important activities of social control, based on findings from an ethnographic study in one acute psychiatric unit in Australia. These practices are acknowledged as key modes of nursing surveillance. Contrary to past work, they are regarded as productive for engendering civil conduct among patients in acute psychiatric settings. We reframe these activities of surveillance as liberal therapeutic practices in themselves, to the extent that they assist patients to achieve treatment goals and promote self‐surveillance and self‐control. Instead of effacing practices of control, we encourage nurses to discriminate between more and less liberal modes of control in everyday practice and to build their skills in liberal controlling strategies.

Power is a matter of authority and control. It can be wielded either consciously or unconsciously, and it can be either overt or latent. Using a structured questionnaire, this study set out to describe nurses’ opinions about the exercise of power in basic care situations in both acute and long-term care. The questionnaire was organized into four categories in which items concerned: power in obligatory daily activities; power in activities necessitated by obligatory activities; power (...) in voluntary activities; and power in activities that take into account the patient’s characteristics. The samples consisted of 228 nurses from five medical and surgical wards of district hospitals, and 233 nurses from five geriatric units of a community health centre and from one nursing home in Finland. The final response rate was 65% (acute care 76%; long-term care 55%). Data analysis was based on statistical methods. The results showed that, in the nurses’ own opinion, negative power is exercised only in certain situations and in the patient’s best interest, when for instance there are concerns that something may happen to the patient.

Key ideas in the work of Michel Foucault are explored and applied to the organized pursuit of knowledge in higher education. His association of power and knowledge accounts for deeply rooted practices in higher education that would need to be mediated or overcome for there to be a revolution in inquiry to occur, such as the one advanced by Nicholas Maxwell. Foucault’s concepts of disciplinary power and bio-power, and how they act to manage the behavior of free (...) citizens, are described. These concepts are then applied to free inquiry, to show how the activity of individual inquirers is managed and how critical inquiry is controlled. The management of inquiry involving four norms, two of them intrinsic to inquiry and the other two extrinsic, is explained. The potential of Foucault’s concept of discursive formations is introduced as a means of reconceiving inquiry to overcome these impediments to a revolution in inquiry. (shrink)

Using an explicit task cuing paradigm, we tested whether masked cues can trigger task-set activation, which would suggest that unconsciously presented stimuli can impact cognitive control processes. Based on a critical assessment of previous findings on the priming of task-set activation, we present two experiments with a new method to approach this subject. Instead of using a prime, we varied the visibility of the cue. These cues either directly signaled particular tasks in Experiment 1, or certain task transitions in (...) Experiment 2. While both masked task and transition cues affected task choice, only task cues affected the speed of task performance. This observation suggests that task-specific stimulus–response rules can be activated only by masked cues that are uniquely associated with a particular task. Taken together, these results demonstrate that unconsciously presented stimuli have the power to activate corresponding task sets. (shrink)

Cross-disciplinary studies carried out lately by Russian scholars discovered a causal relationship between the three variables: technological potential, cultural regulation quality, and social sustainability. The patterns called techno-humanitarian balance law, states that the higher production and war technologies' power, the more refined the behaviorregulation means that are required for self-preservation of the society. The article shows that the law has controlled social selection for all of human history and prehistory, discarding unbalanced social organisms, as far as they could not (...) cope with ecological and geopolitical crises, which had been caused by their own activities. It also shows how successive growth of instrumental opportunities in long-term retrospection has dramatically led to the consecutive perfection of cultural and psychological regulation mechanisms. Relevant calculations, comparative-anthropological evidence, and historical illustrations are provided. Regularities in mental processes are described that precede and accompany crisis-causing behavior, to certain extent regardless of population's historical and cultural peculiarities. (shrink)

Dominant food systems, based on industrial methods and corporate control, are in a state of flux. To enable the transition towards more sustainable and just food systems, food movements are claiming new roles in governance. These movements, and the initiatives they spearhead, are associated with a range of labels (e.g., food sovereignty, food justice, and community food security) and use a variety of strategies to enact change. In this paper, we use the concept of relational fields to conduct a (...) post-hoc analysis of nine cases, examining how social movement organizations and other actors actively create new deliberative governance spaces. We argue that successes are related to the “power to convene,” a process-oriented approach that increases movements’ capacity to mobilize; leverage different types of power; and integrate, coordinate, and build a systems-oriented vision. The power to convene and create deliberative spaces is demonstrated in a variety of contexts and often results in outcomes that further movement aims, including policy change and repositioning food movement actors vis-à-vis others in the field. Our findings suggest that success is not only measured as policy outcomes, but as an advantageous repositioning of social movement actors that enables them to be part of governance processes beyond simple policy advocacy.

In this paper, I explain the kinematics of non-ideal metalinguistic disagreement. This occurs when one speaker has greater control in the joint activity of pairing contents with words in a context. I argue that some forms of non-ideal metalinguistic disagreement are deeply worrying, namely those that involves certain power imbalances. In such cases, a speaker possesses illegitimate control in metalinguistic disagreement owing to the operation of identity prejudice. I call this metalinguistic injustice. The wrong involves restricting a (...) speaker from participating in the processes that determine the epistemic/linguistic resources of a conversation, and/or undermining a speaker's ability to affect metalinguistic outcomes.

Political thought, from Aristotle to Lefebvre, has placed importance on the control of space as an activity of political power. Extraordinary measures taken by global policy-makers since the early 2020s as part of efforts to to combat the pandemic have included mass lock-downs, closed borders, social distancing and other forms of spatial control. Importantly, spaces dedicated to religious worship (churches, etc.) were subjected to extraordinary regulation. In the exercise of this new control of space, social (...) class='Hi'>control has played an important role (obligation to declare one’s health condition, incitement to denounce offenders...) fostered by the authorities through various means of new social education, generating new social habits in terms of the management of space. Religious freedom and the autonomy of the Church thus faced new challenges as a result of the extraordinary control of religious space by civil power and the pressure of social control. The new forms of control incorporated into our habits deserve to be critically reviewed in our search for true spaces of freedom that are not sacrificed in the name of supposed science. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Active Euthanasia and Assisted SuicidePat Milmoe McCarrick (bio)Although the President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research in its 1983 report, Deciding to Forego Life-Sustaining Treatment, described the words and terms "euthanasia," "right to die," and "death with dignity" as slogans or code words—"empty rhetoric," (I, p. 24), the literature reviewed for this Scope Note continues to use these terms. Therefore, (...) to discuss the termination of a patient's life by a physician at the patient's request, the phrase active euthanasia is used, and the supplying of a means by a physician whereby a patient can end his or her life is referred to as assisted suicide.Euthanasia, either as the "good death" from classical Greek or "mercy killing" to end unbearable suffering in the dying, has long been a topic of interest in western civilization (III, Brody 1989). In recent years, public awareness of this discussion about control over the time of one's death has been informed by a series of well-publicized events. They include the November 1991 rejection by a vote of 54 percent to 46 percent of the Washington state Initiative 119, which would have allowed the option of requesting one's physician to "aid-in-dying" for adult patients in a "medically terminal condition" (V, Gross 1991); two medical journal articles describing physician's actions in helping bring death to two patients (V, Anonymous 1988; V, Quill 1991); Dr. Jack Kevorkian's assistance in the suicide of three women (V, Belkin 1990; V, Wilkerson 1991); and the best seller status of a how-to book on committing suicide with opiates obtained from a physician (III, Humphry 1991).For the most part, material included in the annotated bibliography in Scope Note 18 has been chosen from works published in the four years since "It's Over, Debbie" (V, Anonymous 1988) appeared in early January 1988 in the Journal of the American Medical Association.Dr. Edmund D. Pellegrino (V, 1991, pp. 3118-19) presented opposing views about active voluntary euthanasia as follows:Those who favor voluntary euthanasia argue that it is a beneficent and compassionate act; it respects autonomy by preserving the patient's control of the manner, method, [End Page 79] and timing of death; it takes the matter outside the reach of "medical power" (accessed in this Scope Note's bibliography at V, Fletcher 1973; V, Nowell-Smith 1989) and scrupulosity; and it prevents the injustice that allows some patients to choose death by refusal of life-support measures, while denying others the right to do so by active euthanasia....The opponents of active euthanasia argue that it undermines the value of, and respect for, all human life (V, Kass 1989; V, Coyle 1990; V, Singer 1990). They fear that guidelines cannot avoid sliding down the "slippery slope" to involuntary euthanasia and selective devaluation of the lives of the most vulnerable among us.... If euthanasia is legal, it is predicted that patients will feel subtle pressure to conform so as to relieve the economic and emotional burdens they impose on family and friends.Euthanasia, its opponents further argue, is socially destructive: it undermines trust in physicians, desensitizes society to killing, and imperils the ground already gained in legitimating passive euthanasia(IV, Wolf 1989).Physicians were not particularly involved with a patient's death until after World War II when participation grew in proportion to the growth of technology. Since the complex, life-sustaining equipment that could forestall death was located in a hospital, death itself became almost completely medicalized (V, Dagi 1991). For terminally ill persons who would like to die a painless death, either by their own hand or with assistance, physicians have almost a monopoly on obtaining strong drugs for distribution to patients (V, Abrams 1990).Active euthanasia for human beings is not legalized anywhere in the world (V, VonDrehle 1991). It is classified as homicide or murder in all fifty states and in Great Britain, Canada, Australia, and the Phillippines (V, Nerland 1989). Twentysix states in the United States prohibit assisted suicide by statute (V, Rosenblum 1990).In 1969 in the Netherlands, a physician named Jan Hendrik van... (shrink)

In the early 1970s, the major industrial states were preparing to shift to nuclear fission as their principal source of electrical power. But that change has not occurred. In part, this is due to a growing public recognition that techniques and institutions for management of spent nuclear fuel, separated plutonium, and long-lived radioactive wastes are not yet fully developed. The consequent pressures for resolution have spurred a series of often ill-defined and sometimes contradictory attempts to promote international cooperation and (...) control of hazardous activities. How are these varied suggestions to be compared and evaluated? By what criteria can plans be selected that are likely to be both effective and negotiable? In this study, Gene I. Rochlin, physicist and social scientist, explores the technical, political, and institutional aspects of international nuclear export and fuel cycle policies. He categorizes existing proposals and suggests way to develop new ones that better promote both national and international goals. Dr. Rochlin argues neither for nor against the use of nuclear power or plutonium fuels. Instead, he addresses the question of how international arrangements could be reached that might jointly satisfy the objective of the several key nations, yet not be too difficult to negotiate. He concludes that a major fault has been the tendency to improvise arrangements for specific technical or industrial operations. As a result, overall social and political goals have become the bargaining points for compromise. Yet attempts to simultaneously resolve all problems are unlikely to prove fruitful. Dr. Rochlin suggests instead the formation of institutions organized around more limited social, political, and technical objectives, even at the expense of excluding some nations or omitting some aspects of the nuclear fuel cycle. Only by so doing, he argues, can immediate agreements be reached that preserve the potential for more comprehensive future arrangements without sacrificing industrial, environmental, or nonproliferation goals. This important book will be of interest to scientists, social scientists, government officials, and others concerned with the problems of plutonium management and nuclear wastes. (shrink)

To gain a deeper understanding of consumers' brain responses during a real-time in-store exploration could help retailers to get much closer to costumers' experience. To our knowledge, this is the first time the specific role of touch has been investigated by means of a neuroscientific approach during consumer in-store experience within the field of sensory marketing. This study explores the presence of distinct cortical brain oscillations in consumers' brain while navigating a store that provides a high level of sensory arousal (...) and being allowed or not to touch products. A 16-channel wireless electroencephalogram was applied to 23 healthy participants, with interest in cosmetics but naive about the store explored. Subjects were assigned to two experimental conditions based on the chance of touching or not touching the products. Cortical oscillations were explored by means of power spectral analysis of the following frequency bands: delta, theta, alpha, and beta. Results highlighted the presence of delta, theta, and beta bands within the frontal brain regions during both sensory conditions. The absence of touch was experienced as a lack of perception that needs cognitive control, as reflected by Delta and Theta band left activation, whereas a right increase of Beta band for touch condition was associated with sustained awareness on the sensory experience. Overall, EEG cortical oscillations' functional meaning could help highlight the neurophysiological implicit responses to tactile conditions and the importance of touch integration in consumers' experience.

The review of activity of local governments of Leningrad on the solution of social problems is presented in article in the period of the Great Patriotic War and restoration of municipal economy during the post-war period. The considerable attention is paid to questions of ensuring activity of the population and the main directions of social policy. Consequences of the public regress caused by war, which detained for many decades development of the social sphere in the country, are not studied yet. (...) In this regard, the judgment of process of overcoming of these consequences, research of the principles of work, methods and forms of administrative activities for the organization of full-fledged life of citizens during the recovery post-war period and in the next decades is of special interest. Completion of World War II entailed changes in a control system of the country - as it is known, extraordinary bodies of authority and management of a wartime in the capital and on places were abolished. Management of restoration and maintenance of full functioning life support system of the cities and areas transferred to local governments of the Soviet power - to city and regional councils of deputies and their constantly operating executive committees. The role of the social sphere in modern conditions more and more increases in improvement of economy, development of democratic processes. The scientific analysis of activity of the central and local authorities for protection and providing the population in years of war and the post-war period gives more deep understanding of role and importance of social questions in life of society. It reveals historical experience of creation, development and implementation of effective mechanism of such activity, that experience is useful for modern management practice of state and local authorities.

In addition, we show the stochastic threshold for the extinction of the disease. Furthermore, numerical examples are discussed to confirm the theoretical result. (shrink)

ObjectiveWhen regaining consciousness, patients who emerge from a minimally conscious state (EMCS) present with different levels of functional disability, which pose great challenges for treatment. This study investigated the frontoparietal activity in EMCS patients and its effects on functional disability.Materials and methodsIn this preliminary study, 12 EMCS patients and 12 healthy controls were recruited. We recorded a resting-state scalp electroencephalogram (EEG) for at least 5 min for each participant. Each patient was assessed using the disability rating scale (DRS) to determine (...) the level of functional disability. We analyzed the EEG power spectral density and sensor-level functional connectivity in relation to the patient’s functional disability.ResultsIn the frontoparietal region, EMCS patients demonstrated lower relative beta power (P < 0.01) and higher weighted phase lag index (wPLI) values in the theta (P < 0.01) and gamma (P < 0.01) bands than healthy controls. The frontoparietal theta wPLI values of EMCS patients were positively correlated with the DRS scores (rs = 0.629, P = 0.029). At the whole-brain level, EMCS patients only had higher wPLI values in the theta band (P < 0.01) than healthy controls. The whole-brain theta wPLI values of EMCS patients were also positively correlated with the DRS scores (rs = 0.650, P = 0.022). No significant difference in the power and connectivity between the frontoparietal region and the whole brain in EMCS patients was observed.ConclusionEMCS patients still experience neural dysfunction, especially in the frontoparietal region. However, the theta connectivity in the frontoparietal region did not increase specifically. At the level of the whole brain, the same shift could also be seen. Theta functional connectivity in the whole brain may underlie different levels of functional disability. (shrink)

Selective attention depends on goal-directed and stimulus-driven modulatory factors, each relayed by different brain rhythms. Under certain circumstances, stress-related states can change the balance between goal-directed and stimulus-driven factors. However, the neuronal mechanisms underlying these changes remain unclear. In this study, we explored how psychosocial stress can modulate brain rhythms during an attentional task and a task-free period. We recorded the EEG and ECG activity of 42 healthy participants subjected to either the Trier Social Stress Test, a controlled procedure to (...) induce stress, or a comparable control protocol, flanked by an attentional task, a 90 s of task-free period and a state of anxiety questionnaire. We observed that psychosocial stress induced an increase in heart rate, self-reported anxiety, and alpha power synchronization. Also, psychosocial stress evoked a relative beta power increase during correct trials of the attentional task, which correlates positively with anxiety and heart rate increase, and inversely with attentional accuracy. These results suggest that psychosocial stress affects performance by redirecting attentional resources toward internal threat-related thoughts. An increment of endogenous top-down modulation reflected an increased beta-band activity that may serve as a compensatory mechanism to redirect attentional resources toward the ongoing task. The data obtained here may contribute to designing new ways of clinical management of the human stress response in the future and could help to minimize the damaging effects of persistent stressful experiences.

Active networking is an exciting new paradigm in digital networking that has the potential to revolutionize the manner in which communication takes place. It is an emerging technology, one in which new ideas are constantly being formulated and new topics of research are springing up even as this book is being written. This technology is very likely to appeal to a broad spectrum of users from academia and industry. Therefore, this book was written in a way that enables all (...) these groups to understand the impact of active networking in their sphere of interest. Information services managers, network administrators, and e-commerce developers would like to know the potential benefits of the new technology to their businesses, networks, and applications. The book introduces the basic active networking paradigm and its potential impacts on the future of information handling in general and on communications in particular. This is useful for forward-looking businesses that wish to actively participate in the development of active networks and ensure a head start in the integration of the technology in their future products, be they applications or networks. Areas in which active networking is likely to make significant impact are identified, and the reader is pointed to any related ongoing research efforts in the area. The book also provides a deeper insight into the active networking model for students and researchers, who seek challenging topics that define or extend frontiers of the technology. It describes basic components of the model, explains some of the terms used by the active networking community, and provides the reader with taxonomy of the research being conducted at the time this book was written. Current efforts are classified based on typical research areas such as mobility, security, and management. The intent is to introduce the serious reader to the background regarding some of the models adopted by the community, to outline outstanding issues concerning active networking, and to provide a snapshot of the fast-changing landscape in active networking research. Management is a very important issue in active networks because of its open nature. The latter half of the book explains the architectural concepts of a model for managing active networks and the motivation for a reference model that addresses limitations of the current network management framework by leveraging the powerful features of active networking to develop an integrated framework. It also describes a novel application enabled by active network technology called the Active Virtual Network Management Prediction (AVNMP) algorithm. AVNMP is a proactive management system; in other words, it provides the ability to solve a potential problem before it impacts the system by modeling network devices within the network itself and running that model ahead of real time.

In March, 2004, the rural northern California county of Mendocino voted to ban the propagation of all genetically modified organisms (GMOs). This county was the first, and only, U.S. region to adopt such a ban despite widespread activism against biotechnology. Using a civic agriculture perspective, this article explores how local actors in this small county were able to take on the agri-biotechnology industry. I argue that by localizing the issue, the citizens of Mendocino County were able to ignite a highly (...) effective, decentralized and grassroots social movement against which powerful, and well-funded, pro-biotechnology entities were unable to compete. The social problem of biotechnology was embedded in issues of mass concern to Mendocino County residents, such as democracy, equity, distribution of power, and corporate control over local life. The campaign was an arena for “local problem-solving activities organized around food and agriculture” (Lyson 2004, p. 103). However, though localizing this issue was key for generating a successful ban against the propagation of GMOs at the county level, the local orientation of the No to GMOs movement created a barrier for scaling-up and transferring this success to the wider anti-biotechnology movement.

Tree branches near the electric power transmission lines are of great threat to the electricity supply. Nowadays, the tasks of clearing threatening tree branches are still mostly operated by hand and simple tools. Traditional structures of the multirotor aerial robot have the problem of fixed structure and limited performance, which affects the stability and efficiency of pruning operation. In this article, in order to obtain better environmental adaptability, an active deformable trees-pruning aerial robot is presented. The deformation of (...) the aerial robot is implemented through two ways, arm telescopic and folding. In order to suppress the influence of internal and external disturbances on the system, Active Disturbance Rejection Control technology is adopted to build the flight controller. Firstly, active deformation aerial robot structure is given, followed by system dynamic model establishment under wind disturbance using the Newton–Euler method. Also, the analysis of the gusts influence on the system is considered. Then, the active deformation aerial robot system is decoupled into a combination of six SISO systems, so that a disturbance rejection controller is designed. Finally, the expanded state observer and the nonlinear state error feedback law are used to inspect and compensate the disturbance. Simulation results of attitude and position tracking as well as the antidisturbance capability show that the active deformation aerial robot with the ADRC flight controller designed in this paper has excellent attitude control capabilities during flight and trees-pruning operation.

This article explores John Dewey’s conceptualization of the public as polity in his lecture notes from 1928. Dewey’s conceptualization suggests an account of the democratic legitimacy of public regulation of economic activities by focusing on polity members’ mutual interest. Contextualized through Dewey’s involvement in practical politics the article specifies the conceptualization by a policy focus on natural resources and technology, and explores and discusses it through two issues for democratic control over policy development: centralization of power in federal (...) government; and the failure to understand, predict and control consequences of technology. Finally, exploring its relevance in a context of economic globalization the article rearticulates the conceptualization in terms of transnational relations and solidarities, using the transnational peasant organization La Via Campesina as an example.

In this double case study of child psychotherapy, we demonstrate the positive effect of children’s involvement in play activities on their verbal expression of inner emotions and cognitions. Discourse analysis of therapy sessions complemented with the therapist’s reflections show that children who have difficulty in verbalizing hard feelings and cognitions gain control of the communicative situation by getting involved in playful activities. Therapists’ verbal entrance into play can be used to negotiate the therapist–child relationship in terms of power (...) and solidarity. (shrink)

Using the exemplary case of 19th-century American state penitentiaries, the authors explore penitentiary control from the perspective of sensing agents who navigate a controlled sensory ecology – the prison, as structured by institutional rules, differential power relations, and architectural plans. Moving beyond Foucault’s Discipline and Punish and Goffman’s Asylums, they stress a pragmatist approach to understanding human sensing and explain inmates’ creativity under constraints. Employing wardens’ disciplinary journals and other secondary reports, the article emphasizes three theoretical issues that (...) explain why Panoptical prisons’ attempts to control sense experiences can sometimes fail: architectural designs that inadequately negotiate the contradictory demands of visual and acoustic control; inmates’ active mobilization of perceptible objects as means of resistance; and power differences between prison authorities and inmates that prevent actors from sharing a common sensory field. The authors’ overarching goal is to advance, via pragmatism, a sensory analysis of institutional control. (shrink)

In this paper I discuss the power of corporations as epistemic agents. Corporations need to hold certain forms of knowledge in order to develop and produce goods and services. Intellectual property is meant to incentivize them to do so, in ways that orient their activities towards the public good. However, corporations often use their knowledge strategically, not only within markets, but also in the processes that set the rules for markets. I discuss various historical examples, including the so-called “tobacco (...) strategy” of creating doubt about scientific evidence, and argue that as long as corporations are set up as profit-oriented entities, it is a dangerous strategy to provide them with too much epistemic power. I suggest various policies for reigning in this form of corporate power, for example regulations on PR activities. I then turn to the power of digital corporations, which is based on their collection and analysis of data. These kinds of companies, and the technologies they use, make the control of corporations as epistemic agents all the more urgent for democratic societies. (shrink)

Women's Power To Be Loud: The Authority of the Discourse and Authority of the Text in Mary Dorcey's Irish Lesbian Poetic Manifesto "Come Quietly or the Neighbours Will Hear" The following article aims to examine Mary Dorcey's poem "Come Quietly or the Neighbours Will Hear," included in the 1991 volume Moving into the Space Cleared by Our Mothers. Apart from being a well-known and critically acclaimed Irish poet and fiction writer, the author of the poem has been, from its (...) beginnings, actively involved in lesbian rights movement. Dorcey's poem "Come Quietly or the Neighbours Will Hear" is to be construed from a perspective of lesbian and feminist discourse, as well as a cultural, sociological and political context in which it was created. While analyzing the poem, the emphasis is being paid to the intertwining of various ideological and subversive assumptions, their competing for importance and asserting authority over one another, in line with, and sometimes, against the grain of the textual framework. In other words, Dorcey's poem introduces a multilayered framework that draws heavily on various sources: the popular culture idiom, religious discourse, the text even employs, in some parts, crime and legal jargon, but, above all, it relies upon sensuous lesbian experience where desire and respect for the other woman opens the emancipating space allowing for redefining of one's personal and textual location. As a result of such a multifarious interaction, unrepresented and unacknowledged Irish women's standpoints may come to the surface and become articulated, disrupting their enforced muteness that the controlling heteronormative discourse has attempted to ensure. In Dorcey's poem, the operating metaphor of women's silence, conceived of, at first, as the need to conceal one's sexual identity in fear of social ostracism and contempt of the "neighbours," is further equated with the noiseless, solitary and violent death of the anonymous woman, the finding of whose body was reported on the news. In both cases, the unwanted Irish women's voices of either agony, during the unregistered by anybody misogynist bloodshed that took place inside the flat, or the forbidden sounds of lesbian sexual excitement, need to be censored and stifled, not to disrupt an idealized image of the well-established family and heteronormative patterns. In the light of the aforementioned parallel, empowered by the shared bodily and emotional closeness with her female lover, and already bitterly aware that silence in discourse is synonymous with textual, or even, actual death, the speaker in "Come Quietly or the Neighbours Will Hear" comes to claim her own agency and makes her voice heard by others and taken into account.

The aim of Kant's Order of Reason is to give an account of Kant's conception of rational agency that clarifies and explains both the scope and nature of such activity, and elucidates the centrality of Kant's account of rational determination for his mature critical philosophy. As I see it, the core Kantian insight concerning rational determination is that the capacity for rationality is based in and derived from the capacity for exercising a very specific kind of causality in the world–namely, (...) free, or controlled, causality -/- The book consists of three parts. In the first I provide a historically contextualized but nevertheless rigorous metaphysical framework for understanding Kant's conception of mental activity, his theory of freedom, and its importance for understanding his conception of the difference between rational and non-rational forms of activity. I then argue that Kant has a control-centered or "enkratic" account of rational activity and agency. According to this view, control is the central and essential aspect of all rational activity, and a rational being is one that can exercise her diverse powers, or use her diverse intellectual faculties, in a manner that is under her own control. Building on this structure, in part two I show how Kant applies his conception of controlled activity to the various forms of activity of which the rational mind is capable, in increasing order of complexity (i.e. attention, conception, judgment, inference, and comprehension). I then put this account to work with respect to longstanding disputes regarding self-consciousness, reason, evil, and alienation. (shrink)

Frequent observation: sexualities, self‐surveillance, confession and the construction of the active patient Following Foucault’s analyses of the development of the disciplinary power of the medical gaze, this paper describes the themes that are relocating the ‘active patient’ as the central object of health scrutiny by professionals. A key element in these discourses has been the deployment of power through disciplinary knowledge and techniques of social control through ritual forms of confession, thereby positing the patient/client as (...) the subject of self‐surveillance. The individual is also engaged their own sexuality, performativity and ‘truths’ of sexual experience. These Foucauldian insights have constructed the notion of surveillance medicine, whereby with the assistance of professional technologies, not only the patient’s body but also the ‘self’ can be probed through incitement to confess. However, the actor is not docile; resistances to disciplinary techniques are evident and within the professional practices of the clinic, there is resistance to the power of the erotic. The paper draws on recent research on the social construction of male sexualities in the fields of genitourinary practice, and explores how the ceremonial practices of the clinic engage with the rise of surveillance medicine and the medicalisation of everyday life. The individual actor is exhorted to engage in increased sexual and medical self‐surveillance and to be recruited in the project of becoming an ‘active patient’. It concludes with an examination of some of the implications this surveillance of self may have for practitioners in terms of power and the professional lens through which the sexualised, symbolic body is viewed.

Our approach is based on a tri-partite method of integrating psychodynamic hypotheses, cognitive subliminal processes, and psychophysiological alpha power measures. We present ten social phobic subjects with three individually selected groups of words representing unconscious conflict, conscious symptom experience, and Osgood Semantic negative valence words used as a control word group. The unconscious conflict and conscious symptom words, presented subliminally and supraliminally, act as primes preceding the conscious symptom and control words presented as supraliminal targets. With alpha (...) power as a marker of inhibitory brain activity, we show that unconscious conflict primes, only when presented subliminally, have a unique inhibitory effect on conscious symptom targets. This effect is absent when the unconscious conflict primes are presented supraliminally, or when the target is the control words. Unconscious conflict prime effects were found to correlate with a measure of repressiveness in a similar previous study (Shevrin et al., 1992, 1996). Conscious symptom primes have no inhibitory effect when presented subliminally. Inhibitory effects with conscious symptom primes are present, but only when the primes are supraliminal, and they did not correlate with repressiveness in a previous study (Shevrin et al., 1992, 1996). We conclude that while the inhibition following supraliminal conscious symptom primes is due to conscious threat bias, the inhibition following subliminal unconscious conflict primes provides a neurological blueprint for dynamic repression: it is only activated subliminally by an individual's unconscious conflict and has an inhibitory effect specific only to the conscious symptom. These novel findings constitute neuroscientific evidence for the psychoanalytic concepts of unconscious conflict and repression, while extending neuroscience theory and methods into the realm of personal, psychological meaning.

Existing accounts of mechanistic causation are not suited for understanding causation in biological and neural mechanisms because they do not have the resources to capture the unique causal structure of control heterarchies. In this paper, we provide a new account on which the causal powers of mechanisms are grounded by time-dependent, variable constraints. Constraints can also serve as a key bridge concept between the mechanistic approach to explanation and underappreciated work in theoretical biology that sheds light on how biological (...) systems channel energy to actively respond to the environment in adaptive ways, perform work, and fulfill the requirements to maintain themselves far from equilibrium. We show how the framework applies to several concrete examples of control in simple organisms as well as the nervous system of complex organisms. (shrink)

Neuroimaging technologies have improved our understanding of deception and also exhibit their potential in revealing the origins of its neural mechanism. In this study, a quantitative power analysis method that uses the Welch power spectrum estimation of functional near-infrared spectroscopy signals was proposed to examine the brain activation difference between the spontaneous deceptive behavior and controlled behavior. The power value produced by the model was applied to quantify the activity energy of brain regions, which can serve as (...) a neuromarker for deception detection. Interestingly, the power analysis results generated from the Welch spectrum estimation method demonstrated that the spontaneous deceptive behavior elicited significantly higher power than that from the controlled behavior in the prefrontal cortex. Meanwhile, the power findings also showed significant difference between the spontaneous deceptive behavior and controlled behavior, indicating that the reward system was only involved in the deception. The proposed power analysis method for processing fNIRS data provides us an additional insight to understand the cognitive mechanism of deception. (shrink)

BackgroundFreezing of gait is a disabling burden for Parkinson’s disease patients with poor response to conventional therapies. Combined deep brain stimulation of the subthalamic nucleus and substantia nigra moved into focus as a potential therapeutic option to treat the parkinsonian gait disorder and refractory FoG. The mechanisms of action of DBS within the cortical-subcortical-basal ganglia network on gait, particularly at the cortical level, remain unclear.MethodsTwelve patients with idiopathic PD and chronically-implanted DBS electrodes were assessed on their regular dopaminergic medication in (...) a standardized stepping in place paradigm. Patients executed the task with DBS switched off, conventional STN DBS and combined STN+SN DBS and were compared to healthy matched controls. Simultaneous high-density EEG and kinematic measurements were recorded during resting-state, effective stepping, and freezing episodes.ResultsClinically, STN+SN DBS was superior to conventional STN DBS in improving temporal stepping variability of the more affected leg. During resting-state and effective stepping, the cortical activity of PD patients in STIM OFF was characterized by excessive over-synchronization in the theta, alpha, and high-beta band compared to healthy controls. Both active DBS settings similarly decreased resting-state alpha power and reduced pathologically enhanced high-beta activity during resting-state and effective stepping compared to STIM OFF. Freezing episodes during STN DBS and STN+SN DBS showed spectrally and spatially distinct cortical activity patterns when compared to effective stepping. During STN DBS, FoG was associated with an increase in cortical alpha and low-beta activity over central cortical areas, while with STN+SN DBS, an increase in high-beta was prominent over more frontal areas.ConclusionsSTN+SN DBS improved temporal aspects of parkinsonian gait impairment compared to conventional STN DBS and differentially affected cortical oscillatory patterns during regular locomotion and freezing suggesting a potential modulatory effect on dysfunctional cortical-subcortical communication in PD.

This paper analyses the use of metaphor in discourses around the “superweed” Palmer amaranth. Most weed scientists associated with the US public agricultural extension system dismiss the term superweed. However, together with the media, they indirectly encourage aggressive control practices by actively diffusing the framing of herbicide resistant Palmer amaranth as an existential threat that should be eradicated at any cost. We use argumentative discourse analysis to better understand this process. We analyze a corpus consisting of reports, policy briefs, (...) and press releases produced by state extension services, as well as articles from professional and popular magazines and newspapers quoting extension specialists and/or public sector weed scientists or agronomists. We show how the superweed discourse is powered by negative metaphors, and legitimizes aggressive steps to eradicate the weed. This discourse reinforces the farmers’ techno-optimism master frame, contributes to deskilling of farmers and sidelines ethical concerns. (shrink)

Physical fatigue negatively affects postural control, resulting in impaired balance performance in young and older adults. Similar effects on postural control can be observed for mental fatigue mainly in older adults. Controversial results exist for young adults. There is a void in the literature on the effects of fatigue on balance and cortical activity. Therefore, this study aimed to examine the acute effects of PF and MF on postural sway and cortical activity. Fifteen healthy young adults aged 28 (...) ± 3 years participated in this study. MF and PF protocols comprising of an all-out repeated sit-to-stand task and a computer-based attention network test, respectively, were applied in random order. Pre and post fatigue, cortical activity and postural sway were tested during a challenging bipedal balance board task. Absolute spectral power was calculated for theta, alpha-2, beta-1, and beta-2 in frontal, central, and parietal regions of interest and baseline-normalized. Inference statistics revealed a significant time-by-fatigue interaction for CoPd and CoPv, and a significant main effect of time for CoP variability. Post hoc analyses showed a significant increase in CoPd and CoPv following PF but not MF. For cortical activity, a significant time-by-fatigue interaction was found for relative alpha-2 power in parietal areas. Post hoc tests indicated larger alpha-2 power increases after PF compared to MF. In addition, changes in parietal alpha-2 power and measures of postural sway did not correlate significantly, irrespective of the applied fatigue protocol. No significant changes were found for the other frequency bands, irrespective of the fatigue protocol and ROI under investigation. Thus, the applied PF protocol resulted in increased postural sway and CoP variability accompanied by enhanced alpha-2 power in the parietal ROI while MF led to increased CoP variability and alpha-2 power in our sample of young adults. Potential underlying cortical mechanisms responsible for the greater increase in parietal alpha-2 power after PF were discussed but could not be clearly identified as cause. Therefore, further future research is needed to decipher alternative interpretations. (shrink)

The article examines the key conclusions and recommendations to candidate countries and potential candidates for accession, set out by the European Commission in the annual Communication on the EU enlargement policy in 2022. For better understanding of the essence of the Commission’s Communication, this article the author analyses the realities faced by the EU with the beginning of the Russian Federation’s full-scale war against Ukraine. According to scholars and experts, the war changed Europe more profoundly than any event since the (...) end of the Cold War. It is found that the war clearly emphasized the attractiveness of EU membership and strengthened its transformative power, which was formed thanks to the values, diversity of the societies of the Member States, fundamental freedoms and way of life of the Union. In this context, one can agree with the statement of scholars that the real challenges that the EU cannot avoid if it wants to become more authoritative and strategically autonomous are the strengthening, not the weakening of the European level (institutional and legal systems, common EU policies) under a strict democratic control. The analysis of the conclusions and recommendations in the Commission’s Communication allowed us to conclude that after the Russian invasion of Ukraine, the policy of EU enlargement was returned to the forefront of the EU’s agenda. Evidence of this was, firstly, granting the status of a candidate for accession to Ukraine and Moldova and a potential candidate – to Georgia, and, secondly, a joint search by the EU and its Member States for ways to activate and speed up the process of European integration of the countries of the Western Balkans region. In addition, it should be noted that the cross-cutting themes of the Commission’s conclusions and recommendations are EU security and energy policy, key areas of the Green Course, in particular decarbonization of the economy, as well as the issue of recovery after the COVID-19 pandemic. A separate emphasis in the Commission’s Communication is placed on the reforms continued by the countries of the Western Balkans, which are necessary to fulfill the accession criteria. (shrink)

The resting-state human electroencephalogram power spectrum is dominated by alpha and theta oscillations, and also includes non-oscillatory broadband activity inversely related to frequency. Gratton proposed that alpha and theta oscillations are both related to cognitive control function, though in a complementary manner. Alpha activity is hypothesized to facilitate the maintenance of representations, such as task sets in preparation for expected task conditions. In contrast, theta activity would facilitate changes in representations, such as the updating of task sets in (...) response to unpredicted task demands. Therefore, theta should be related to reactive control, while alpha may be more relevant to proactive control. Less is known about the possible relationship between 1/f activity and cognitive control, which was analyzed here in an exploratory fashion. To investigate these hypothesized relationships, we recorded eyes-open and eyes-closed resting-state EEG from younger and older adults and subsequently tested their performance on a cued flanker task, expected to elicit both proactive and reactive control processes. Results showed that alpha power and 1/f offset were smaller in older than younger adults, whereas theta power did not show age-related reductions. Resting alpha power and 1/f offset were associated with proactive control processes, whereas theta power was related to reactive control as measured by the cued flanker task. All associations were present over and above the effect of age, suggesting that these resting-state EEG correlates could be indicative of trait-like individual differences in cognitive control performance, which may be already evident in younger adults, and are still similarly present in healthy older adults.

Electroencephalography-neurofeedback has become a valuable tool in the field of psychology, e.g., to improve cognitive function. Nevertheless, a large percentage of NF users seem to be unable to control their own brain activation. Therefore, the aim of this study was to examine whether a different kind of visual feedback could positively influence NF performance after one training session. Virtual reality seems to have beneficial training effects and has already been reported to increase motivational training aspects. In the present study, (...) we tested 61 young healthy adults to investigate, whether 3D VR-based NF training has a more beneficial effect on the sensorimotor rhythm power increase than a mere 2D conventional NF paradigm. In the 3D group, participants had to roll a ball along a predefined path in an immersive virtual environment, whereas the 2D group had to increase the height of a bar. Both paradigms were presented using VR goggles. Participants completed one baseline and six feedback runs with 3 min each, in which they should try to increase SMR power over Cz. Half of the participants received real feedback whereas the other half received sham feedback. Participants receiving 3D VR-based feedback showed a linear increase in SMR power over the feedback runs within one training session. This was the case for the real as well as for the sham 3D feedback group and might be related to more general VR-related effects. The 2D group receiving the conventional bar feedback showed no changes in SMR power over the feedback runs. The present study underlines that the visual feedback modality has differential effects on the NF training performance and that 3D VR-based feedback has advantages over conventional 2D feedback.

ObjectiveSchizophrenia is a mental disorder that is characterized by progressive cognitive impairment. Objective measures of cognitive function may provide reliable neurobiomarkers for patients with schizophrenia. The goal of the current work is to explore the correlation between resting theta power and cognitive performance in patients with schizophrenia.MethodsTwenty-two patients with schizophrenia and 23 age-, sex-, and education-matched healthy controls were included in this study. The MATRICS Consensus Cognitive Battery was used for cognitive evaluation and the Positive and Negative Syndrome Scale (...) for evaluation of clinical symptoms. EEGs were acquired in the resting state with closed and opened eyes. Between the two groups, we compared the relative theta power and examined their relationship with cognitive performance.ResultsCompared to healthy controls, patients with schizophrenia showed significantly higher theta power, both with eyes closed and open. When the eyes were open, negative correlations were found in patients with schizophrenia between theta power in the central and parietal regions with processing speed scores, and between the theta power of the Pz electrode and verbal learning and reasoning and problem-solving scores. In the control group, theta power over the Fz electrode was negatively correlated with processing speed.ConclusionsOur findings showed that theta activity increased in certain brain regions during resting state in schizophrenia. Negative associations between resting theta power over the parietal-occipital regions with MCCB domains scores suggest that altered theta activity can be used as a neurobiological indicator to predict cognitive performance.

In the late 1940s in Spain, a group of young scholars, most of them newly appointed university lecturers, gained control of Arbor, the promotional journal of the Consejo Superior de Investigaciones Científicas (CSIC: The Spanish National Research Council), the institution that General Franco had founded after the Spanish Civil War (1936–9) to organize Spanish science. This group constituted the intellectual core of the more reactionary, Catholic traditionalist faction of Franco’s regime, and they coveted greater political power, in competition (...) with other factions of the regime. Lacking the opportunity to launch an overt political campaign within a dictatorship, the group started a fight for the cultural conquest of Spain. In this cultural struggle for hegemony, journals, magazines, cultural associations, publishing houses, newspapers, and cultural centers became their weapons. By analyzing this faction’s views on and activities within the popularization of science, particularly regarding theories of evolution, this article argues that popular discourse on science played a critical role in the cultural struggle both as a “safe” channel in which to forward their claims and as a tool to gather popular attention through topics of general interest. A covert political campaign was conducted through the popularization of science and this, in turn, fueled the construction of a public sphere for science in a dictatorial context. Scientific popularization became a much-appreciated tool to achieve cultural hegemony and, as such, it also became a central element in constructing and legitimating the ideological foundations of Franco’s regime.

Error-related electroencephalographic signals have been widely studied concerning the human cognitive capability of differentiating between erroneous and correct actions. Midfrontal error-related negativity and theta band oscillations are believed to underlie post-action error monitoring. However, it remains elusive how early monitoring activity is trackable and what are the pre-response brain mechanisms related to performance monitoring. Moreover, it is still unclear how task-specific parameters, such as cognitive demand or motor control, influence these processes. Here, we aimed to test pre- and post-error (...) EEG patterns for different types of motor responses and investigate the neuronal mechanisms leading to erroneous actions. We implemented a go/no-go paradigm based on keypresses and saccades. Participants received an initial instruction about the direction of response to be given based on a facial cue and a subsequent one about the type of action to be performed based on an object cue. The paradigm was tested in 20 healthy volunteers combining EEG and eye tracking. We found significant differences in reaction time, number, and type of errors between the two actions. Saccadic responses reflected a higher number of premature responses and errors compared to the keypress ones. Nevertheless, both led to similar EEG patterns, supporting previous evidence for increased ERN amplitude and midfrontal theta power during error commission. Moreover, we found pre-error decreased theta activity independent of the type of action. Source analysis suggested different origin for such pre- and post-error neuronal patterns, matching the anterior insular cortex and the anterior cingulate cortex, respectively. This opposite pattern supports previous evidence of midfrontal theta not only as a neuronal marker of error commission but also as a predictor of action performance. Midfrontal theta, mostly associated with alert mechanisms triggering behavioral adjustments, also seems to reflect pre-response attentional mechanisms independently of the action to be performed. Our findings also add to the discussion regarding how salience network nodes interact during performance monitoring by suggesting that pre- and post-error patterns have different neuronal sources within this network.

Effective content moderation by social platforms is both important and difficult; numerous issues arise from the volume of information, the culturally sensitive and contextual nature of that information, and the nuances of human communication. Attempting to scale moderation, social platforms are increasingly adopting automated approaches to suppressing communications that they deem undesirable. However, this brings its own concerns. This paper examines the structural effects of algorithmic censorship by social platforms to assist in developing a fuller understanding of the risks of (...) such approaches to content moderation. This analysis shows that algorithmic censorship is distinctive for two reasons: in potentially bringing all communications carried out on social platforms within reach and in potentially allowing those platforms to take a more active, interventionist approach to moderating those communications. Consequently, algorithmic censorship could allow social platforms to exercise an unprecedented degree of control over both public and private communications. Moreover, commercial priorities would be inserted further into the everyday communications of billions of people. Due to the dominance of the web by a few social platforms, this may be difficult or impractical to escape for many people, although opportunities for resistance do exist. (shrink)

Autism spectrum disorders (ASD) are thought to result in part from altered cortical excitatory-inhibitory balance; this pathophysiology may impact the generation of oscillations on EEG. We investigated premotor-parietal cortical physiology associated with praxis, which has strong theoretical and empirical associations with ASD symptomatology. 25 children with high-functioning ASD (HFA) and 33 controls performed a praxis task involving the pantomiming of tool use, while EEG was recorded. We assessed task-related modulation of signal power in alpha and beta frequency bands. Compared (...) with controls, subjects with HFA showed 27% less left central (motor/premotor) beta (18-22 Hz) event-related desynchronization (ERD) (p = 0.030), as well as 24% less left parietal alpha (7-13 Hz) ERD (p = 0.046). Within the HFA group, blunting of central ERD attenuation was associated with impairments in clinical measures of praxis imitation (r = -0.4; p = 0.04) and increased autism severity (r = 0.48; p = 0.016). The modulation of central beta activity is associated, among other things, with motor imagery, which may be necessary for imitation. Impaired imitation has been associated with core features of ASD. Altered modulation of oscillatory activity may be mechanistically involved in those aspects of motor network function that relate to the core symptoms of ASD. (shrink)
