This paper empirically raises and examines the question of ‘conceptual control’: To what extent are competent thinkers able to reason properly with new senses of words? This question is crucial for conceptual engineering. This prominently discussed philosophical project seeks to improve our representational devices to help us reason better. It frequently involves giving new senses to familiar words, through normative explanations. Such efforts enhance, rather than reduce, our ability to reason properly, only if competent language users are able to (...) abide by the relevant explanations, in language comprehension and verbal reasoning. This paper examines to what extent we have such ‘conceptual control’ in reasoning with new senses. The paper draws on psycholinguistic findings about polysemy processing to render this question empirically tractable and builds on recent findings from experimental philosophy to address it. The paper identifies a philosophically important gap in thinkers’ control over the key process of stereotypical enrichment and discusses how conceptual engineers can use empirical methods to work around this gap in conceptual control. The paper thus empirically demonstrates the urgency of the question of conceptual control and explains how experimental philosophy can empirically address the question, to render conceptual engineering feasible as an ameliorative enterprise.

In this review, I discuss recent advances in philosophical and psychological approaches to self-control. The review is divided in 4 parts, in which I discuss: a) different conceptions of self-control; b) standard methods for studying it; c) some models of how self-control is exercised; and d) the connections between self-control and other relevant psychological constructs. The review was originally commissioned by the John Templeton Foundation to provide an informative overview that would knit together different strands of (...) current debates in the field. It is meant to be useful to well-informed audiences, as well as new-comers to the discussion. (shrink)

In this paper, we discuss Armstrong’s account of attachment-based claims to natural resources, the kind of rights that follow from attachment-based claims, and the limits we should impose on such claims. We hope to clarify how and why attachment matters in the discourse on resource rights by presenting three challenges to Armstrong’s theory. First, we question the normative basis for certain attachment claims, by trying to distinguish more clearly between different kinds of attachment and other kinds of claims. Second, we (...) highlight the need to supplement Armstrong’s account with a theory of how to weigh different attachment claims so as to establish the normative standing that different kinds of attachment claims should have. Third, we propose that sustainability must be a necessary requirement for making attachment claims to natural resources legitimate. Based on these three challenges and the solutions we propose, we argue that attachment claims are on the one hand narrower than Armstrong suggests, while on the other hand they can justify more far-reaching rights to control than Armstrong initially considers, because of the particular weight that certain attachment claims have.

Emotion is widely agreed to have two dimensions, valence and arousal. Few studies have explored the effect of emotion on conflict adaptation by considering both of these, which could have dissociate influence. The present study aimed to fill the gap as to whether emotional valence and arousal would exert dissociable influence on conflict adaptation. In the experiments, we included positive, neutral, and negative conditions, with comparable arousal between positive and negative conditions. Both positive and negative conditions have higher arousal than (...) neutral ones. In Experiment 1, by using a two-colour-word Flanker task, we found that conflict adaptation was enhanced in both positive and negative contexts compared to a neutral context. Furthermore, this effect still existed when controlling stimulus–response repetitions in Experiment 2, which used a four-colour-word Flanker task. The findings suggest emotional arousal enhances conflict adaptation, regardless of emotional valence. Thus, future studies should consider emotional arousal when studying the effect of emotion on conflict adaptation. Moreover, the unique role of the emotional context in conflict-driven cognitive control is emphasised. (shrink)

What drives us to make decisions? Future-Minded explores the psychological processes of agency and control. If you've ever wondered why we think of coincidences as matters of fate rather than the result of the laws of probability, this book provides the answer. From memory and reasoning to our experiences of causality and consciousness, it unpicks the mechanisms we use on a daily basis to help us predict, plan for and attempt to control the future. Future-Minded - Features a (...) wealth of real world examples to help you engage with this fast-developing area. - Provides clear analysis of psychological experiments and their findings to explain the evidence behind the theory. Thought-provoking and highly topical, Future-Minded is fascinating reading for psychology students studying cognition or consciousness, and for anyone interested in understanding how we try to determine the future.

What is the role of conscious visual experience in the control and guidance of human behaviour? According to some recent treatments, the role is surprisingly indirect. Conscious visual experience, on these accounts, serves the formation of plans and the selection of action types and targets, while the control of 'online' visually guided action proceeds via a quasi-independent non-conscious route. In response to such claims, critics such as (Wallhagen [2007], pp. 539-61) have suggested that the notions of control (...) and guidance invoked are unacceptably vague, and that that the image of 'zombie systems' guiding action fails to take account of the possibility that there is genuine but unconceptualized, unnoticed, and/or unreportable experience taking place and guiding or controlling the actions. I address both sets of concerns. I try to show that refining and clarifying the key notions of control and guidance leaves the original argument intact, as does the appeal to unconceptualized, unnoticed, or unreportable experiences. The exercise serves, however, to highlight an important complex of considerations concerning the relations between control, agency, and experience. Better understanding these relations is, I suggest, an important source of insights concerning the nature of phenomenal experience. (shrink)

Sentences such as “The ship was sunk to collect the insurance” exhibit an unusual form of anaphora, implicit control, where neither anaphor nor antecedent is audible. The non-finite reason clause has an understood subject, PRO, that is anaphoric; here it may be understood as naming the agent of the event of the host clause. Yet since the host is a short passive, this agent is realized by no audible dependent. The putative antecedent to PRO is therefore implicit, which it (...) normally cannot be. What sorts of representations subserve the comprehension of this dependency? Here we present four self-paced reading time studies directed at this question. Previous work showed no processing cost for implicit vs. explicit control, and took this to support the view that PRO is linked syntactically to a silent argument in the passive. We challenge this conclusion by reporting that we also find no processing cost for remote implicit control, as in: “The ship was sunk. The reason was to collect the insurance.” Here the dependency crosses two independent sentences, and so cannot, we argue, be mediated by syntax. Our Experiments 1–4 examined the processing of both implicit (short passive) and explicit (active or long passive) control in both local and remote configurations. Experiments 3 and 4 added either “3 days ago” or “just in order” to the local conditions, to control for the distance between the passive and infinitival verbs, and for the predictability of the reason clause, respectively. We replicate the finding that implicit control does not impose an additional processing cost. But critically we show that remote control does not impose a processing cost either. Reading times at the reason clause were never slower when control was remote. In fact they were always faster. Thus, efficient processing of local implicit control cannot show that implicit control is mediated by syntax; nor, in turn, that there is a silent but grammatically active argument in passives.

The Theory of Planned Behavior predicts that a combination of attitudes, perceived norms, and perceived behavioral control predict intentions, and that intentions ultimately predict behavior. Previous studies have found that the TPB can predict students’ engagement in plagiarism. Furthermore, the General Theory of Crime suggests that self-control is particularly important in predicting engagement in unethical behavior such as plagiarism. In Study 1, we incorporated self-control in a TPB model and tested whether norms, attitudes, and self-control predicted (...) intention to plagiarize and plagiarism behavior. The best statistical fit for the path-analytic model was achieved when a direct path from self-control to plagiarism engagement was specified. In Study 2, we added a measure of perceived behavioral control and split the measurement of norms into descriptive and injunctive components. This study found that both self-control and perceived-behavioral control additively contributed to the prediction of plagiarism and the path-analytic model achieved its best fit when direct paths from perceived norms to plagiarism behavior were specified. These studies suggest that setting strong anti-plagiarism norms, such as by the use of honor codes, and seeking to enhance students’ self-control may reduce engagement in plagiarism. (shrink)

Key elements of Randolph Clarke's libertarian account of freedom that requires both agent-causation and non-deterministic event-causation in the production of free action is assessed with an eye toward determining whether agent-causal accounts can accommodate the truth of judgments of moral obligation.

Although it seems commonsensical to say that one cannot merely have too little, but also too much self-control, the philosophical debate has largely focused on failures of self-control rather than its potential excesses. There are a few notable exceptions. But, by and large, the issue of having too much self-control has not received a lot of attention. This paper takes another careful look at the commonsensical position that it is possible to have too much self-control. One (...) key insight that will emerge is that there are certain important confusions surrounding this view. Once these are removed, however, we are led to the conclusion that there need not be anything intrinsically problematic about being a paragon of self-control. (shrink)

In “Control, Responsibility, and Moral Assessment” Angela Smith defends her nonvoluntarist theory of moral responsibility against the charge that any such view is shallow because it cannot capture the depth of judgments of responsibility. Only voluntarist positions can do this since only voluntarist positions allow for control. I argue that Smith is able to deflect the voluntarists’ criticism, but only with further resources. As a voluntarist, I also concede that Smith’s thesis has force, and I close with a (...) compromise position, one that allows for direct moral responsibility for the nonvoluntary, but also incorporates a reasonable control condition.

Surprisingly little attention has been paid to the nature of conscious control. As a result, experiments suggesting that we lack conscious control over our actions cannot be properly evaluated. Joshua Shepherd (2015; 2021) aims to fill this gap. His proposal is grounded in the standard causalist account of action, according to which, simply put, bodily movements are controlled by the agent if and only if they are caused, in the right way, by the relevant psychological states. In this (...) paper, I argue that the proposal does not succeed in distinguishing between mere causation and actual control; it does not solve the problem of deviant causation. On the basis of my criticism, Anscombean action theory promises to offer a valuable perspective. It suggests that an important function of consciousness is to integrate an action into a rational whole. If this is on the right track, it supports Shepherd’s overall claim that the importance of consciousness for action control is often underestimated, because this contribution of consciousness may often go unnoticed in experimental settings.

Internet based process control usage has grown in the past years. Industry field demands were behind this, and it ranges from factory, office and home automation to tasks simplifications and cost reduction. In this book a hardware interface circuit and a software system used to control the temperature and level of a liquid tank is described. The advantage of the designed interface circuit is its simplicity and low cost. The same can be true for the software system in (...) which we used C and Java programs to accomplish the communication. Both C and Java can be obtained freely and the development cost could be small. C language has been used to communicate with the designed interface circuit due to its strength in low level operations and communication with ports and hardware. In Java we have used mainly the Servlet for communication between the Client and the Server, which is a new approach and more reliable approach than the CGI based method that has common problems of speed and data persistence. This book is useful for people and researchers working in the field of control, remote access and computer based control. (shrink)

The human masticatory system is a complex functional unit characterized by a multitude of skeletal components, muscles, soft tissues, and teeth. Muscle activation dynamics cannot be directly measured on live human subjects due to ethical, safety, and accessibility limitations. Therefore, estimation of muscle activations and their resultant forces is a longstanding and active area of research. Reinforcement learning (RL) is an adaptive learning strategy which is inspired by the behavioral psychology and enables an agent to learn the dynamics of an (...) unknown system via policy-driven explorations. The RL framework is a well-formulated closed-loop system where high capacity neural networks are trained with the feedback mechanism of rewards to learn relatively complex actuation patterns. In this work, we are building on a deep RL algorithm, known as the Soft Actor-Critic, to learn the inverse dynamics of a simulated masticatory system, i.e., learn the activation patterns that drive the jaw to its desired location. The outcome of the proposed training procedure is a parametric neural model which acts as the brain of the biomechanical system. We demonstrate the model’s ability to navigate the feasible three-dimensional (3D) envelope of motion with sub-millimeter accuracies. We also introduce a performance analysis platform consisting of a set of quantitative metrics to assess the functionalities of a given simulated masticatory system. This platform assesses the range of motion, metabolic efficiency, the agility of motion, the symmetry of activations, and the accuracy of reaching the desired target positions. We demonstrate how the model learns more metabolically efficient policies by integrating a force regularization term in the RL reward. We also demonstrate the inverse correlation between the metabolic efficiency of the models and their agility and range of motion. The presented masticatory model and the proposed RL training mechanism are valuable tools for the analysis of mastication and other biomechanical systems. We see this framework’s potential in facilitating the functional analyses aspects of surgical treatment planning and predicting the rehabilitation performance in post-operative subjects. (shrink)

Actions that are intended to produce harmful consequences can fail to achieve their desired effects in numerous ways. We refer to action sequences in which harmful intentions are thwarted as deviant causal chains. The culpable control model of blame (CCM)is a useful tool for predicting and explaining the attributions that observers make of the actors whose harmful intentions go awry. In this paper, we describe six types of deviant causal chains; those in which: an actor’s attempt is obviated by (...) the intervention of another person or the environment; the intended effects could not have been produced regardless of the actor’s behavior; other causes diminish the actor’s causal role; the actor brings about foreseen but undesired consequences as a result of pursuing his or her focal goal; the focal action produces a chain of increasingly remote causal events; and the actor derives unforeseen benefits from his or her nefarious actions. A basic assumption of the CCM in these cases is that attributions for the participants’ actions will depend on positive and negative evaluations of their intentions and behaviors. We describe empirical findings that are consistent with this assumption, and predict other findings for causal deviance phenomena that have not yet been investigated empirically. (shrink)

In this paper, I provide policymakers, who rely on science to address their missions, with two arguments for improving science for social benefits. I argue for a refined concept of social robustness that can distinguish socially appropriate cases of political reliance on science from inappropriate ones. Both of the constituents are essential for evaluating the social suitability of science-relevant policy or action. Using four cases of population control, I show that socially inappropriate political reliance on science can make science (...) epistemically and socially harmful. Moreover, I argue that such an evaluation process should be supported by a political culture of mutual criticism within science and society. This demands freedom of expression and critical examination of science-relevant policy consequences in view of a sufficiently wide range of social value commitments. This paper suggests that the same considerations of social robustness and political culture of mutual criticism should be of general relevance for policymakers engaging in debates about science and values such as those regarding climate change.

Parents typically direct many aspects of their children’s lives and often believe that they deserve protection from interference by governments and third parties. Justifications for such parental control rights sometimes rely on the interests of children or of society. But they can also rely directly on parental interests. This paper considers whether parental control rights can be justified based on parental interests. It????first considers two parental interests sometimes put forward as warranting parental control rights: an interest in (...) intimacy and an interest in acting as a????fiduciary. The????first fails as a justification for parental rights because intimacy is unlikely to be undermined by most intrusions. The second fails because it misunderstands the nature of????fiduciary roles. The paper then considers an alternative parental interest in nurturing, counselling, and educating. This interest requires both authenticity and discretion to play a meaningful role in a parent’s life and facilitating this interest warrants protecting parental control rights. (shrink)

Polypeptide growth factors (mitogens) which stimulate proliferation of fibroblasts and epithelial cells also rapidly activate transmembrane ion transport systems. The mitogen‐induced Na+ influx is due to the activation of a Na+/H+ antiport. Recent methodological developments allow, for the first time, precise measurements of the factors that control activation of the Na+/H+ antiport by these agents, and provide the tools needed to assess the physiological significance of this exchange mechanism.

This paper focuses on studying containment control problem with switching communication graphs of continuous-time heterogeneous multiagent systems where the control inputs are constrained in a nonconvex set. A nonlinear projection algorithm is proposed to address the problem. We discuss the stability and containment control of the system with switching topologies and nonconvex control input constraints under three different conditions. It is shown that all agents converge to the convex hull of the given leaders ultimately while staying (...) in the nonconvex set under the premise that at least one directed path from leaders to the agents exists in each bounded time interval. Finally, the validity of the results obtained in this paper is verified by simulation. (shrink)

This paper presents an adaptive fuzzy sliding-mode controller for multiple Euler–Lagrange systems communicated with directed topology. Based on the graph theory and Lyapunov–Krasovskii functions, a delay-dependent sufficient condition for the existence of sliding surfaces is given in terms of linear matrix inequalities. The asymptotic stability is analyzed by using the Lyapunov method in the presence of unknown parametric dynamics, actuator faults, and time-varying delays. The usage of adaptive techniques is to adapt the unknown parameters so that the objective of globally (...) asymptotic stability is achieved. Finally, simulation results are provided to illustrate the effectiveness of the proposed control scheme. (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 processes underlying motor decision-making have recently caught considerable amount of scientific attention, focusing on the integration of empirical evidence from sensorimotor control research with psychological theories and computational models on decision-making. Empirical studies on motor decision-making suggest that the kinematics of goal-directed reaching movements are sensitive to the level of target uncertainty during movement planning. However, the source of uncertainty as a relevant factor influencing the process of motor decision-making has not been sufficiently considered, yet. In this study, (...) we test the assumption that the source of target uncertainty has an effect on motor decision-making, which can be proven by analyzing movement variability during the time course of movement execution. Ten healthy young adults performed three blocks with 66 trials of goal-directed reaching movements in each block, across which the source and level of reach target uncertainty at movement onset were manipulated (“no uncertainty”, “extrinsic uncertainty”, “intrinsic uncertainty”). Fingertip position of the right index finger was recorded using an optical motion tracking system. Standard kinematic measures (i.e. path length and movement duration) as well as variability of fingertip position across the time course of movement execution and at movement end were analyzed. In line with previous studies, we found that a high level of extrinsic target uncertainty leads to increased overall movement duration, which could be attributed to increased path length in this condition, as compared to intrinsic and no target uncertainty (all p <.001). Movement duration and path length did not show any differences between the latter two conditions. However, the time course analysis of movement variability revealed significant differences between these two conditions, with increased variability of fingertip position in the presence of intrinsic target uncertainty (Condition × Sampling point: p =.01), though considerably less than under high extrinsic target uncertainty (p ≤.001). These findings suggest that both the level and source of uncertainty have a significant effect on the processing of potential action plans during motor decision-making, which can be revealed through the analysis of the time course of movement variability at the end-effector level.

The main objective of this thesis is to defend an account of the control that agents possess over their actions from the perspective of the causal theory of action, that is, a theory that sees actions as events caused by internal states of their agents. The explanatory strategy that is employed for this purpose consists in addressing three interdependent and fundamental problems concerning the possibility of this type of control. The first problem arises from the possibility of controlling (...) an action that is itself transitively caused by previous events. The answer given to this problem is grounded on a careful description of basic actions and on an identification of the internal states that function as the sources of control. The second problem emerges from a variety of causal deviance, namely, a conceptually possible scenario that satisfies the requirements for a bodily movement to be under the control of its agent without this movement being intuitively under the control of its agent. The answer given to this problem comes from the examination of the sources of the intuitions associated with causal deviance and from the recognition of the causal contribution of epistemic features present in the antecedents of an action. The third problem results from the possibility of producing an action that can only be partially controlled. This is problematic if one accepts that producing an action entails controlling it, as is suggested in this thesis. The reply given to this problem adapts an intention-based account of action guidance to the needs of an account of degrees of control, while remaining compatible with the proposal that producing an action is sufficient to control it.

This article presents a cross-cultural exploration of the interaction between religion and family in the lives of women. It focuses on elderly Middle Eastern Jewish women who, during the course of their life spans, moved from a conflicting to a complementary experience of family and religion. The author argues that opposition between religion and family seldom arises for women who control their own time or resources, or who control a domestic sphere they themselves see as sacred. Women who (...) wish to conduct their religious lives in the public sphere, especially in the context of an extrafamilial hierarchy or as religious professionals, are likely to come into conflict with their families over issues of competition for their time or allegiance. Official religious doctrines are not likely to determine how particular women experience family and religion; even women who maneuver within the same theological framework may experience the relationship between family and religion in very different ways.

The basic nuts and bolts underlying human behavior remain mysterious from a scientific point of view. Everyday acts -- naming an object, suppressing the urge to say something, or grabbing a waiter's attention with a "cappuccino, please" -- remain difficult to understand from a mechanistic standpoint. Despite these challenges, research has begun to illuminate, not only the basic processes underlying human action production, but the role of conscious processing in the control of behavior. This Research Topic, "Consciousness and the (...) Control of Action," is devoted to surveying and synthesizing these developments from disparate fields of study. (shrink)

The freedom provided by the parametric control can be fully used to find a controller to satisfy the robustness criteria.

Often the greatest challenges in our relationships with others center on control. Using the Torah wisdom of his heritage and the remarkable insight of his profession, Rabbi Abraham J. Twerski, M. D. once again enlightens us on key issues that.

The problem of finite-time tracking control is discussed for a class of uncertain nonstrict-feedback time-varying state delay nonlinear systems with full-state constraints and unmodeled dynamics. Different from traditional finite-control methods, a C 1 smooth finite-time adaptive control framework is introduced by employing a smooth switch between the fractional and cubic form state feedback, so that the desired fast finite-time control performance can be guaranteed. By constructing appropriate Lyapunov-Krasovskii functionals, the uncertain terms produced by time-varying state delays (...) are compensated for and unmodeled dynamics is coped with by introducing a dynamical signal. In order to avoid the inherent problem of “complexity of explosion” in the backstepping-design process, the DSC technology with a novel nonlinear filter is introduced to simplify the structure of the controller. Furthermore, the results show that all the internal error signals are driven to converge into small regions in a finite time, and the full-state constraints are not violated. Simulation results verify the effectiveness of the proposed method. (shrink)

Malaria is a Plasmodium parasitic disease transmitted by infected female Anopheles mosquitoes. Climatic factors, such as temperature, humidity, rainfall, and wind, have significant effects on the incidence of most vector-borne diseases, including malaria. The mosquito behavior, life cycle, and overall fitness are affected by these climatic factors. This paper presents the results obtained from investigating the optimal control strategies for malaria in the presence of temperature variation using a temperature-dependent malaria model. The study further identified the temperature ranges in (...) four different geographical regions of sub-Saharan Africa, suitable for mosquitoes. The optimal control strategies in the temperature suitable ranges suggest, on average, a high usage of both larvicides and adulticides followed by a moderate usage of personal protection such as bednet. The average optimal bednet usage mimics the solution profile of the mosquitoes as the mosquitoes respond to changes in temperature. Following the results from the optimal control, this study also investigates using a temperature-dependent model with insecticide-sensitive and insecticide-resistant mosquitoes the impact of insecticide-resistant mosquitoes on disease burden when temperature varies. The results obtained indicate that optimal bednet usage on average is higher when insecticide-resistant mosquitoes are present. Besides, the average bednet usage increases as temperature increases to the optimal temperature suitable for mosquitoes, and it decreases after that, a pattern similar to earlier results involving insecticide-sensitive mosquitoes. Thus, personal protection, particularly the use of bednets, should be encouraged not only at low temperatures but particularly at high temperatures when individuals avoid the use of bednets. Furthermore, control and reduction of malaria may be possible even when mosquitoes develop resistance to insecticides. (shrink)

A novel fuzzy control scheme with adaptation algorithms is developed for robot manipulators’ system. At the beginning, one adjustable parameter is introduced in the fuzzy logic system, the robot manipulators system with uncertain nonlinear terms as the master device and a reference model dynamic system as the slave robot system. To overcome the limitations such as online learning computation burden and logic structure in conventional fuzzy logic systems, a parameter should be used in fuzzy logic system, which composes fuzzy (...) logic system with updated parameter laws, and can be formed for a new fashioned adaptation algorithms controller. The error closed-loop dynamical system can be stabilized based on Lyapunov analysis, the number of online learning computation burdens can be reduced greatly, and the different kinds of fuzzy logic systems with fuzzy rules or without any fuzzy rules are also suited. Finally, effectiveness of the proposed approach has been shown in simulation example. (shrink)

Many office workers use computers and the Internet not only to get their daily jobs done but also to deal with their personal businesses. Therefore employers nowadays monitor their employees electronically to prevent the misuse of the company resources. The use of electronic monitoring in organizations causes issues of trust and privacy. This study is dedicated to developing a conceptual model on the two issues under electronic monitoring. Control, considered as the essence of the definition of privacy as well (...) as the foundation of the control model in the theory of procedural justice, plays an important role to people’s privacy concerns and trust. People’s perceived‐self, as essential in the group‐value model in the theory of procedural justice and in the cultural studies, also plays an important role to people’s privacy concerns and trust. This study presents research hypotheses on trust and privacy under electronic surveillance based on the two models of the theory of procedural justice, social identity theory, and cultural studies.

Many plants are adapted to flower at particular times of year, to ensure optimal pollination and seed maturation. In these plants flowering is controlled by environmental signals that reflect the changing seasons, particularly daylength and temperature. The response to daylength varies, so that plants isolated at higher latitudes tend to flower in response to long daylengths of spring and summer, while plants from lower latitudes avoid the extreme heat of summer by responding to short days. Such responses require a mechanism (...) for measuring time, and the circadian clock that regulates daily rhythms in behaviour also acts as the timer in the measurement of daylength. Plants from high latitudes often also show an extreme response to temperature called vernalisation in which flowering is repressed until the plant is exposed to winter temperatures for an extended time. Genetic approaches in Arabidopsis have identified a number of genes that control vernalisation and daylength responses. These genes are described and models presented for how daylength might regulate flowering by controlling their expression by the circadian clock.

Before the passage of the US Immigration Act of 1924, governments of migrant-receiving countries decided whether to admit most prospective immigrants only after they arrived at the border; afterward, the United States and then later other migrant-receiving states required prospective migrants and visitors to apply for visas in their country of residence before coming—an institution that Zolberg has termed “remote control.” Previous scholars wrote about remote control in terms of how it increased the capacity of states to reduce (...) immigration, protect their societies from external threats, and maintain sovereignty, but did not analyze in detail how it did so. Here I analyze three ways through which remote control was a model for a more general revolution in migration control that simultaneously reduced interactions between inhabitants in migrant-receiving societies and those in migrant-sending societies, slowed down the historical reduction of inequality between migrant-sending and migrant-receiving societies, and reduced research and critical awareness within migrant-receiving societies about remote control’s structural impact on societies in general. First, this institution brought more order and precision to the process of individually evaluating prospective visitors. Second, it enabled states to select and define authorized migrants according to their migratory purpose and to force other migrants either to demonstrate enough stamina and strength to enter unauthorized or to die trying. Third, by moving the migrant selection process to migrant-sending societies remote control reduced contact between residents in migrant-receiving societies and prospective migrants in migrant-sending societies. In these three ways, remote control has more generally constrained migratory opportunities and global mobility of individuals between distinct societies. (shrink)

This article analyses representations of Conservative Laestadianism in contemporary Finnish and Finnish-American popular culture. Drawing from political studies, religious studies and cultural studies, the article sheds light on the ways in which Conservative Laestadianism is present in societal debate and in the cultural imagination. Focusing on religious corporeality, the article scrutinises the embodied practices of Conservative Laestadianism and the ways in which the representations participate in making sense of gender, sexuality, and power in religious communities. Contemporary understandings in popular culture (...) are revealed through the detailed analysis of four cultural products of different genres depicting Conservative Laestadianism: a film entitled Kielletty hedelmä, a novel entitled We Sinners, a reality television show entitled Iholla, and a play entitled Taivaslaulu. As a synthesis of the representations of Conservative Laestadianism, the article presents a dynamic triad of care, longing, and control. Furthermore, the article raises questions about the potential of popular culture in calling for a dialogue between Conservative Laestadianism and society at large. (shrink)

According to a widely endorsed claim, intentional action is brought about by an agent’s desires in accordance with these desires’ respective motivational strength. As Jay Wallace has argued, though, this “hydraulic model” of the aetiology of intentional action has a serious flaw: it fails to leave room for genuine deliberative agency. Drawing on recent developments in the debate on self-control, the article argues that Wallace’s criticism can be addressed once we combine the hydraulic model with a so-called “divided mind” (...) account of self-control.

With renewable energy being increasingly connected to power grids, pumped storage plants play a very important role in restraining the fluctuation of power grids. However, conventional control strategy could not adapt well to the different control tasks. This paper proposes an intelligent nonlinear model predictive control strategy, in which hydraulic-mechanical and electrical subsystems are combined in a synchronous control framework. A newly proposed online sequential extreme learning machine algorithm with forgetting factor is introduced to learn the (...) dynamic behaviors of the coupling system. Specifically, the initial learning parameters are optimized by prior-knowledge learning and a new self-adaptive adjustment strategy is also put forward. Subsequently, the stair-like control strategy and artificial sheep algorithm are used in rolling the optimization mechanism to replace the existing complex differential geometric solutions. Comparative experiments are carried out under different working conditions based on a PSP in China. The results show that the influence from coupling factors can be considerable and the proposed MPC strategy indicates superiority in voltage and load adjustment as well as the frequency oscillation suppression.
