There is a fundamental tension in business ethics between the apparent need to ensure ethical conduct through hierarchical control, and the encouragement of individuals' potential for autonomous moral judgement. In philosophical terms, these positions are consequentialist and Kantian, respectively. This paper assumes the former to be the dominant position in practice, and probably in theory also, but regards it as a misplaced extension of the more general managerial tendency to seek and maintain control over employees. While the (...) functions of such control are recognized, the arguments in favour of individuals' moral autonomy are pursued from both a Kantian and a social–theoretic perspective. Reference is made to Kohlberg's research on moral development that provides an insight into how individuals, through participation in debate with colleagues, might become more effective moral agents within organizational settings. This is contrasted with a managerial perspective, which pays lip service to individuals' right to such genuine involvement. The paper considers psychological manipulation and the legitimacy of managerial authority on matters of ethics, as opposed to in the purely technical context. The wider societal significance of such hierarchical power in organizations constitutes an important background to the paper. It is concluded that genuine, non‐manipulative, participation by employees is the way forward for the ethical management of business ethics. (shrink)

Recognized as a simple communicative behavior, referential pointing is cognitively complex because it invites a communicator to consider an addressee's knowledge. Although we know referential pointing is affected by addressees’ physical location, it remains unclear whether and how communicators’ inferences about addressees’ mental representation of the interaction space influence sensorimotor control of referential pointing. The communicative perspective-taking task requires a communicator to point at one out of multiple referents either to instruct an addressee which one should be selected (communicative, (...) COM) or to predict which one the addressee will select (non-communicative, NCOM), based on either which referents can be seen (Level-1 perspective-taking, PT1) or how the referents were perceived (Level-2 perspective-taking, PT2) by the addressee. Communicators took longer to initiate the movements in PT2 than PT1 trials, and they held their pointing fingers for longer at the referent in COM than NCOM trials. The novel findings of this study pertain to trajectory control of the pointing movements. Increasing both communicative and perspective-taking demands led to longer pointing trajectories, with an under-additive interaction between those two experimental factors. This finding suggests that participants generate communicative behaviors that are as informative as required rather than overly exaggerated displays, by integrating communicative and perspective-taking information hierarchically during sensorimotor control. This observation has consequences for models of human communication. It implies that the format of communicative and perspective-taking knowledge needs to be commensurate with the movement dynamics controlled by the sensorimotor system. (shrink)

Hierarchical groups shape social, political, and personal life. This paper concerns the question of how individuals within such groups can be responsible. The paper explores how individual responsibility can be partially grounded in difference-making. The paper concentrates on the control condition of responsibility and takes into view three distinct phenomena of responsibility in hierarchical groups. First, a superior can be responsible for outcomes that her subordinates bring about. Second, a subordinate can be responsible although she is unable (...) to prevent the outcome she brings about. Third, a superior can sometimes be responsible to a greater degree than her subordinates. It is argued that difference-making, as an interpretation of the control condition that partially grounds responsibility, accounts for all three of these phenomena within a limited but significant range of circumstances and can hence partially ground individual moral responsibility in hierarchical groups. The paper provides an element of a theory of individual responsibility to complement theories of corporate responsibility. (shrink)

Human control of action in routine situations involves a flexible interplay between (a) task-dependent serial ordering constraints; (b) top-down, or intentional, control processes; and (c) bottom-up, or environmentally triggered, affordances. In addition, the interaction between these influences is modulated by learning mechanisms that, over time, appear to reduce the need for top-down control processes while still allowing those processes to intervene at any point if necessary or if desired. We present a model of the acquisition and (...) class='Hi'>control of goal-directed action that goes beyond existing models by operationalizing an interface between two putative systems—a routine and a non-routine system—thereby demonstrating how explicitly represented goals can interact with the emergent task representations that develop through learning in the routine system. The gradual emergence of task representations offers an explanation for the transfer of control with experience from the non-routine goal-based system to the routine system. At the same time it allows action selection to be sensitive both to environmental triggers and to biasing from multiple levels within the goal system. (shrink)

Inner speech has been shown to vary in form along several dimensions. Along condensation, condensed inner speech forms have been described, that are supposed to be deprived of acoustic, phonological and even syntactic qualities. Expanded forms, on the other extreme, display articulatory and auditory properties. Along dialogality, inner speech can be monologal, when we engage in internal soliloquy, or dialogal, when we recall past conversations or imagine future dialogues involving our own voice as well as that of others addressing us. (...) Along intentionality, it can be intentional (when we deliberately rehearse material in short-term memory) or it can arise unintentionally (during mind wandering). We introduce the ConDialInt model, a neurocognitive predictive control model of inner speech that accounts for its varieties along these three dimensions. ConDialInt spells out the condensation dimension by including inhibitory control at the conceptualization, formulation or articulatory planning stage. It accounts for dialogality, by assuming internal model adaptations and by speculating on neural processes underlying perspective switching. It explains the differences between intentional and spontaneous varieties in terms of monitoring. We present an fMRI study in which we probed varieties of inner speech along dialogality and intentionality, to examine the validity of the neuroanatomical correlates posited in ConDialInt. Condensation was also informally tackled. Our data support the hypothesis that expanded inner speech recruits speech production processes down to articulatory planning, resulting in a predicted signal, the inner voice, with auditory qualities. Along dialogality, covertly using an avatar’s voice resulted in the activation of right hemisphere homologues of the regions involved in internal own-voice soliloquy and in cerebellar deactivation, consistent with internal model adaptation. Switching from first-person to third-person perspective resulted in activations in precuneus and parietal lobules. Along intentionality, compared with intentional inner speech, mind wandering with inner speech episodes was associated with greater bilateral inferior frontal activation and decreased activation in left temporal regions. This is consistent with the reported subjective evanescence and presumably reflects condensation processes. Our results provide neuroanatomical evidence compatible with predictive control and in favor of the assumptions made in the ConDialInt model. (shrink)

Metaphors from strategic management can be applied effectively to business ethics programs. While effective strategies help implement ethical decisions that are formulated in good faith, ostensibly value-neutral control mechanisms can indirectly affect the substantive nature of policies and decisions themselves. This article examines the effectiveness of various corporate social responsibility implementation strategies. It also addresses the effects of implementation choices on the substantive formulation of ethical decisions and policies.Implementation and evaluation of corporate social responsibility programs through models of responsiveness (...) are integrated into the social policy cycle using four tools: strategic control and performance control approaches, and hierarchical control and contractual control structures. The choices made among these forms of control approaches and structures, which as implementation mechanisms are typically considered to be value-free devices, may affect the substance of corporate social responsibility content. Hierarchical control structures, which use outside directors, tend to be associated with performance control approaches, and are biased towards applying utilitarian approaches to ethical decision making. Contractual control structures are compatable with strategic control approaches, and generally favor the application of principle-based approaches to ethical decision-making. Both the content and the quality of ethical decisions will be affected by differences between hierarchical and contractual control. (shrink)

In this article, we explore the extraction of recursive nested structure in the processing of binary sequences. Our aim was to determine whether humans learn the higher-order regularities of a highly simplified input where only sequential-order information marks the hierarchical structure. To this end, we implemented a sequence generated by the Fibonacci grammar in a serial reaction time task. This deterministic grammar generates aperiodic but self-similar sequences. The combination of these two properties allowed us to evaluate hierarchical learning (...) while controlling for the use of low-level strategies like detecting recurring patterns. The deterministic aspect of the grammar allowed us to predict precisely which points in the sequence should be subject to anticipation. Results showed that participants’ pattern of anticipation could not be accounted for by “flat” statistical learning processes and was consistent with them anticipating upcoming points based on hierarchical assumptions. We also found that participants were sensitive to the structure constituency, suggesting that they organized the signal into embedded constituents. We hypothesized that the participants built this structure by merging recursively deterministic transitions. (shrink)

Markets, companies and various forms of business organizations may all (we have argued) be usefully viewed through the lens of CAS -- the theory of complex adaptive systems. In this chapter, I address one fundamental issue that confronts both the theoretician and the business manager: the nature and opportunities for control and intervention in complex adaptive regimes. The problem is obvious enough. A complex adaptive system, as we have defined it, is soft assembled and largely self-organizing. This means that (...) it is the emergent product of multiple, and often very heterogeneous, interacting factors and forces, and that the crucial interactions are not controlled and orchestrated by an overseeing executive, detailed program, or any other source of strict hierarchical control. There is thus a pressing problem -- are such systems strictly out of control and beyond the reach of useful governance? I shall argue that they are not. Such systems, though initially unfamiliar, can nonetheless be led, influenced and enabled in a variety of ways. (shrink)

We advance an account that grounds cognition, specifically decision-making, in an activity all organisms as autonomous systems must perform to keep themselves viable—controlling their production mechanisms. Production mechanisms, as we characterize them, perform activities such as procuring resources from their environment, putting these resources to use to construct and repair the organism's body and moving through the environment. Given the variable nature of the environment and the continual degradation of the organism, these production mechanisms must be regulated by control (...) mechanisms that select when a production is required and how it should be carried out. To operate on production mechanisms, control mechanisms need to procure information through measurement processes and evaluate possible actions. They are making decisions. In all organisms, these decisions are made by multiple different control mechanisms that are organized not hierarchically but heterarchically. In many cases, they employ internal models of features of the environment with which the organism must deal. Cognition, in the form of decision-making, is thus fundamental to living systems which must control their production mechanisms. (shrink)

Ten years ago, one of us proposed a dynamic hierarchical model of intentions that brought together philosophical work on intentions and empirical work on motor representations and motor control (Pacherie, 2008). The model distinguished among Distal intentions, Proximal intentions, and Motor intentions operating at different levels of action control (hence the name DPM model). This model specified the representational and functional profiles of each type of intention, as well their local and global dynamics, and the ways in (...) which they interact. A core insight of the model was that action control is the result of integrated, coordinated activity across these levels of intention. Since the proposal of the model, empirical and theoretical works in philosophy and cognitive science have emerged that would seem to support and expand on this central insight. In particular, an updated understanding of the nature of sensorimotor processing and motor representations, as well as of how the different levels of intention and control interface and interact, allows for the further specification and precisification of the original DPM model.

One of the most important methods in dealing with the optimization of large, complex systems is that of hierarchical decomposition. The idea is to reduce the overall complex problem into manageable approximate problems or subproblems, to solve these problems, and to construct a solution of the original problem from the solutions of these simpler prob lems. Development of such approaches for large complex systems has been identified as a particularly fruitful area by the Committee on the Next Decade in (...) Operations Research (1988) [42] as well as by the Panel on Future Directions in Control Theory (1988) [65]. Most manufacturing firms are complex systems characterized by sev eral decision subsystems, such as finance, personnel, marketing, and op erations. They may have several plants and warehouses and a wide variety of machines and equipment devoted to producing a large number of different products. Moreover, they are subject to deterministic as well as stochastic discrete events, such as purchasing new equipment, hiring and layoff of personnel, and machine setups, failures, and repairs.

Plants are interpreted as structural hierarchies which are real systems organized through descending constraints. Types of hierarchical groups in plants are (a) cluster by integration, (b) support through attachment, (c) enclosure by encasement (d) dissipative by input of energy and (e) control through variable state switching. Most plant hierarchies are mixtures of these types which explains a number of paradoxes in plant morphology. The traditional means of identifying levels, i.e., cell, tissues, organs, uses a compositional group which is (...) not a hierarchical group but a similarity feature and so is inadequate for describing hierarchies. Hierarchies can be defined by set theory which is more a description of cognitive than real hierarchies and therefore is of little value in describing plant organization. The hierarchical description of a plant emphasizes the immediate physical status of organization which provide, in turn, a physical explanation of development. (shrink)

Researchers often claim that self-control is a skill. It is also often stated that self-control exertions are intentional actions. However, no account has yet been proposed of the skillful agency that makes self-control exertion possible, so our understanding of self-control remains incomplete. Here I propose the skill model of self-control, which accounts for skillful agency by tackling the guidance problem: how can agents transform their abstract and coarse-grained intentions into the highly context-sensitive, fine-grained control (...) processes required to select, revise and correct strategies during self-control exertion? The skill model borrows conceptual tools from ‘hierarchical models’ recently developed in the context of motor skills, and asserts that self-control crucially involves the ability to manage the implementation and monitoring of regulatory strategies as the self-control exercise unfolds. Skilled agents are able do this by means of flexible practical reasoning: a fast, context-sensitive type of deliberation that incorporates non-propositional representations into the formation and revision of the mixed-format intentions that structure self-control exertion. The literatures on implementation intentions and motivation framing offer corroborating evidence for the theory. As a surprising result, the skill of self-control that allows agents to overcome the contrary motivations they experience is self-effacing: instead of continuously honing this skill, expert agents replace it with a different one, which minimizes or prevents contrary motivations from arising in the first place. Thus, the more expert you are at self-control, the less likely you are to use it. (shrink)

Hierarchical organization is an essential characteristic of living things. Although most biologists affirm the concept of living things as hierarchically organized structures, there are widespread differences of interpretation in the meaning of hierarchy and of how the concept of hierarchy applies to living things. One such basic difference involves the distinction between the concept of control hierarchy and classification hierarchy. It is suggested that control hierarchies are distinguished from classification hierarchies in that while the former involve authority (...) relationships between levels, the latter do not. This is illustrated in an analysis of proposed hierarchies of replicators and interactors.The analysis of levels of hierarchies and their relationships also brings up the part-whole problem. An authority relationship between levels implies that the whole has a determining influence on the parts that make up the whole, and that parts have no independent, meaningful existence apart from the whole. The concept of an authority relationship in a part-whole relationship introduces the question of the independence or sovereignty of the components of the subordinate levels in a hierarchically organized living thing. This problem is discussed along with an analysis of the rather novel theory of enkapsis proposed by H. Dooyeweerd, in which he distinguishes part-whole relationships from enkaptic relationships.

Control of DNA supercoiling by the free-energy of hydrolysis of ATP that involves gene expression is analyzed in terms of three levels of unconnected metabolic pathways. These are synthesis and breakdown of topoisomerase mRNAs, synthesis and breakdown of topoisomerase proteins and supercoiling and relaxation of DNA. The so-called square-matrix method previously developed for the control of metabolic pathways, is extended to deal with this hierarchical control system. It turns out that also in this case, the matrix (...) of control coefficients is equal to the inverse of the so-called elasticity matrix, which contains all relevant elasticity coefficients as well as information about the structure and connectedness of the pathways involved. For a simpler case of a hierarchy of two systems, we demonstrate that the explicit matrix inversion method may be replaced by an implicit method in which the regulatory effects that run through the other level are described by an additional elasticy coefficient which may then be treated as if local.

This commentary proposes that “cognitive control” is neither componential nor emergent, but a fundamental feature of behavior. The term “control” requires an operational definition. This is best provided by the negative feedback loop that utilizes behavior to control perception; it does not control behavior per se. In order to model complex cognitive control, Perceptual Control Theory proposes that loops are organized into a dissociable hierarchical network (PCT; Powers, Clark, & McFarland, 1960; Powers, 1973a, (...) 2008). In this way, behavior is dynamically adaptive to environmental disturbances, rather than being formed by, or superimposed upon, learned associations between stimulus and response. (shrink)

Motor control schemes should have an element of control and an element of coordination. The former is a source of initiative and a zroduct of the brain's work (mind, intelligence, or ) while the latter can be viewed as a process with constraints emerging at a hierarchically lower, autonomous level. Limiting scientific analysis to an object smaller than the universe necessarily leads to a hierarchical (cybernetic) approach.

One of the key challenges confronting cognitive science is to discover natural categories of cognitive function. Of special interest is the unity or diversity of cognitive control mechanisms. Evolutionary history is an underutilized resource that, together with neuropsychological and neuroscientific evidence, can help to provide a biological ground for the fractionation of cognitive control. Comparative evidence indicates that primate brain evolution has produced dissociable mechanisms for external action control and internal self-regulation, but that most real-world behaviors rely (...) on a combination of these. The archeological record further indicates the timing and context of distinctively human elaborations to these cognitive control functions, including the gradual emergence of increasingly complex hierarchical action control.

This paper deals with designing a harvesting control strategy for a predator–prey dynamical system, with parametric uncertainties and exogenous disturbances. A feedback control law for the harvesting rate of the predator is formulated such that the population dynamics is asymptotically stabilized at a positive operating point, while maintaining a positive, steady state harvesting rate. The hierarchical block strict feedback structure of the dynamics is exploited in designing a backstepping control law, based on Lyapunov theory. In order (...) to account for unknown parameters, an adaptive control strategy has been proposed in which the control law depends on an adaptive variable which tracks the unknown parameter. Further, a switching component has been incorporated to robustify the control performance against bounded disturbances. Proofs have been provided to show that the proposed adaptive control strategy ensures asymptotic stability of the dynamics at a desired operating point, as well as exact parameter learning in the disturbance-free case and learning with bounded error in the disturbance prone case. The dynamics, with uncertainty in the death rate of the predator, subjected to a bounded disturbance has been simulated with the proposed control strategy. (shrink)

This article demonstrates the potential of using hierarchical Bayesian methods to relate models and data in the cognitive sciences. This is done using a worked example that considers an existing model of category representation, the Varying Abstraction Model (VAM), which attempts to infer the representations people use from their behavior in category learning tasks. The VAM allows for a wide variety of category representations to be inferred, but this article shows how a hierarchical Bayesian analysis can provide a (...) unifying explanation of the representational possibilities using 2 parameters. One parameter controls the emphasis on abstraction in category representations, and the other controls the emphasis on similarity. Using 30 previously published data sets, this work shows how inferences about these parameters, and about the category representations they generate, can be used to evaluate data in terms of the ongoing exemplar versus prototype and similarity versus rules debates in the literature. Using this concrete example, this article emphasizes the advantages of hierarchical Bayesian models in converting model selection problems to parameter estimation problems, and providing one way of specifying theoretically based priors for competing models.

The current study examined the validity of HEXACO personality traits (at the broad trait-level and narrow facet-level) and Self-Control as predictors of counterproductive academic behavior (CAB; at the overall level and specific dimensional level) among college students. We collected data from 483 undergraduate students in South Korea who completed self-report measures of HEXACO personality traits, Self-Control, CAB. Results showed that Conscientiousness (_r_ = −.23) and Honesty-Humility (_r_ = −.25) were significantly correlated with CAB and that Self-Control provided (...) incremental validity over HEXACO personality traits in predicting CAB. The correlations of Conscientiousness and Self-Control with CAB were consistently negative at the facet-level. However, within each HEXACO trait, there was some variability in the strength (and sometimes, the direction) of the relationships between the facet traits and CAB dimensions. Additionally, hierarchical multiple regression analysis results showed that Self-Control provided incremental validity for predicting CAB beyond prediction provided by the HEXACO personality traits. The results provide further support for personality and Self-Control as meaningful predictors of counterproductive academic behavior in college. (shrink)

Under normal circumstances the church would function as an agent of change and transformation, but this article focuses on the church herself that needs radical change if she is to remain relevant in mission and ministry in this current era. Clericalism and the centralisation of hierarchical control can be identified as the root causes of institutional pathology and weakening collegiality. To address clericalism may require the adjustment of seminary training, as in the current system seminarians are nurtured in (...) a sense of separateness, promoting male-ego and feed gender exclusivity and doctrinal self-righteousness. While the seminary was once an instrument of reform in the Catholic Church, established to counter problems such as clerical concubinage and illiteracy, but now it is no longer suitable as it has become the forum that breeds other problems. Priority attention should be paid to purge the church of rampant clericalism, discriminatory scapegoating of gay persons, marginalisation of free thinkers, exclusion of women priests, the perceived moral laxity of family life issues and reception of communion by divorced Catholics without the benefits of annulment. Discrediting the personal authority of the pope is hardly an enlightened option. What ought to be transformed is the centralisation of control and allowing increased localised dominion whereby crises such as sexual abuse scandals could be addressed and solved more speedily and liberally, and limit the need to go to the top for solutions. To wait for centralised, hierarchal structures to deal with urgent issues is not desirable, as speedy accountability is needed to address issues that hurt the church in its entirety. (shrink)

Plagiarism is a problematic issue in universities across the globe (Curtis & Vardanega, 2016 ). This study explored the relationship between negative emotionality and positive attitudes toward plagiarism through the mediation of academic self-efficacy and self-control. Negative emotionality was examined as three components: stress, anxiety, and depression. Self-report surveys were completed by 454 university students to investigate the relationship between negative emotionality and positive attitudes toward plagiarism, as well as the mediating role of academic self-efficacy and self-control in (...) this relationship. The hierarchical multiple regression found that negative emotionality significantly predicted positive attitudes toward plagiarism over and above age and gender (i.e., where male students and younger students were more likely to plagiarise). Furthermore, three mediation analyses showed that academic self-efficacy and self-control mediate the relationship between positive attitudes toward plagiarism and each component of negative emotionality. Considering these results, subsequent research should investigate whether implementing strategies that alleviate stress, anxiety, and depression could increase academic self-efficacy and self-control, which in turn, could then reduce positive attitudes toward plagiarism.

In visual information processing, two kinds of vision are distinguished: vision-for-perception related to the conscious identifi cation of objects, and vision-for-action that deals with visual control of movements. Neuroscience suggests that these two functions are performed by two separate brain neural systems - the ventral and dorsal pathways. Two experiments using behavioural measures were conducted with the objective of exploring any potential interaction between these two functions of vision. The aim was to combine in one task methods allowing for (...) the simultaneous capture of both perceptual global processing and affordance extraction and to check whether they infi uence each other. This aim was achieved by employing the paradigms of Navon and Tucker and Ellis. A compound fi gure was created made up of objects with handles that might or might not have orientation congruent between levels. The results revealed that while the affordance effect occurred every time, the Navon effect appeared only when subjects focused their attention on object elements responsible for inconsistence within compound fi gure. Most importantly, even when these two effects occurred at once, they had no effect on each other. Results from the study failed to confi rm the hypothesis about interaction and gives support to the view that vision-for-perception and vision-for-action tend to act as separate systems. (shrink)

Does self-control require willpower? The question cuts to the heart of a debate about whether self-control is identical with some psychological process internal to the agents or not. Noticeably absent from these debates is systematic evidence about the folk-psychological category of self-control. Here, we present the results of two behavioral studies (N = 296) that indicate the structure of everyday use of the concept. In Study 1, participants rated the degree to which different strategies to respond to (...) motivational conflict exemplify self-control. Participants distinguished between intra-psychic and externally-scaffolded strategies and judged that the former exemplified self-control more than the latter. In Study 2, participants provided various solutions to manage motivational conflict and rated their proposals on effectiveness. Participants produced substantially more intra-psychic strategies, rated them as more effective, and advised them at a higher rate than externally-scaffolded strategies. Taken together, these results suggest that while people recognize a plurality of strategies as genuine instances of self-control, purely internal exercises of self-control are considered more prototypical than their externally-scaffolded counterparts. This implies a hierarchical structure for the folk psychological category of self-control. The concept encompasses a variety of regulatory strategies and organizes these strategies along a hierarchical continuum, with purely intra-psychic strategies at the center and scaffolded strategies in the periphery.

Living systems employ several mechanisms and behaviors to achieve robustness and maintain themselves under changing internal and external conditions. Regulation stands out from them as a specific form of higher-order control, exerted over the basic regime responsible for the production and maintenance of the organism, and provides the system with the capacity to act on its own constitutive dynamics. It consists in the capability to selectively shift between different available regimes of self-production and self-maintenance in response to specific signals (...) and perturbations, due to the action of a dedicated subsystem which is operationally distinct from the regulated ones. The role of regulation, however, is not exhausted by its contribution to maintain a living system’s viability. While enhancing robustness, regulatory mechanisms play a fundamental role in the realization of an autonomous biological organization. Specifically, they are at the basis of the remarkable integration of biological systems, insofar as they coordinate and modulate the activity of distinct functional subsystems. Moreover, by implementing complex and hierarchically organized control architectures, they allow for an increase in structural and organizational complexity while minimizing fragility. Finally, they endow living systems, from their most basic unicellular instances, with the capability to control their own internal dynamics to adaptively respond to specific features of their interaction with the environment, thus providing the basis for the emergence of minimal forms of cognition.

The Recursive Bayesian Net formalism was originally developed for modelling nested causal relationships. In this paper we argue that the formalism can also be applied to modelling the hierarchical structure of mechanisms. The resulting network contains quantitative information about probabilities, as well as qualitative information about mechanistic structure and causal relations. Since information about probabilities, mechanisms and causal relations is vital for prediction, explanation and control respectively, an RBN can be applied to all these tasks. We show in (...) particular how a simple two-level RBN can be used to model a mechanism in cancer science. The higher level of our model contains variables at the clinical level, while the lower level maps the structure of the cell's mechanism for apoptosis. (shrink)

ObjectiveWe wished to explore Parkinson's disease subtypes by clustering analysis based on the multimodal magnetic resonance imaging indices amplitude of low-frequency fluctuation and gray matter volume. Then, we analyzed the differences between PD subtypes.MethodsEighty-six PD patients and 44 healthy controls were recruited. We extracted ALFF and GMV according to the Anatomical Automatic Labeling partition using Data Processing and Analysis for Brain Imaging software. The Ward linkage method was used for hierarchical clustering analysis. DPABI was employed to compare differences in (...) ALFF and GMV between groups.ResultsTwo subtypes of PD were identified. The “diffuse malignant subtype” was characterized by reduced ALFF in the visual-related cortex and extensive reduction of GMV with severe impairment in motor function and cognitive function. The “mild subtype” was characterized by increased ALFF in the frontal lobe, temporal lobe, and sensorimotor cortex, and a slight decrease in GMV with mild impairment of motor function and cognitive function.ConclusionHierarchical clustering analysis based on multimodal MRI indices could be employed to identify two PD subtypes. These two PD subtypes showed different neurodegenerative patterns upon imaging. (shrink)

In this collectively written article, the authors interrogate contemporary power constellations that run between control and connectivity. Regimes of individualism, hierarchies of assumed classifications and imperialistic subjectivities sustain the basis for political control that organises connections and divisions used to justify hierarchical dominations and distributions. This makes anti-oppression practices that value differing forms of connectivity and intra-dependence (between humans, more than humans, disciplines, all things considered to be of different bodies) nearly unimaginable. The authors offer/reconfigure/understand connectivity as (...) a practice acting in and at odds with those controlling political regimes that organise and classify matter(s), while experimenting with their own writing methodology aimed at staying connected. Informed by new materialist feminist practices and ideas, the authors discuss the political stakes of multiple ideas of connectivity within three empirical scenarios: academic labour practices, social media and a digitally established mutual aid community. We trace entangled forces of separation and control shaped by global imperialism, processes of individuation and technological apparatuses and how they perform within these scenarios. This approach is mirrored in our practice of writing together. In an alternative to traditionalised ways of writing, we expand upon an embodied praxis, elaborating on multiple engagements while offering our own connections with these differing situated knowledges. In light of this, the authors write in a diffractive, collective fashion that lies somewhere between a conversation and the strict linearity of typical narratives. (shrink)

Motivation has been the subject of much research in the sport psychology literature, whereas athlete mental health has received limited attention. Motivational complexities in elite sport are somewhat reflected in the mental health literature, where there is evidence for both protective and risk factors for athletes. Notably, few studies have linked motivation to mental health. Therefore, the key objective of this study was to test four mental health outcomes in the motivational sequence posited by the Hierarchical Model of Intrinsic (...) and Extrinsic Motivation: motivational climate  basic psychological needs  motivation  mental health outcomes. Elite team-sport athletes (140 females, 75 males) completed seven psychometric inventories of motivation-related and mental health variables. Overall, the athletes reported positive motivational patterns, with autonomous motivation and task climate being more prevalent than their less adaptive counterparts. Elevated depressive symptoms and poor sleep quality affected nearly half of the cohort. Structural equation modelling supported pathways between motivational climate, basic needs, motivation, and mood, depressive symptoms, sleep quality, and trait anxiety. Specifically, a task climate was positively associated with the three basic psychological needs, and an ego climate was positively associated with competence. Autonomy and relatedness had positive and negative associations with autonomous and controlled forms of motivation, respectively. Controlled motivation regulations were positively associated with the four mental health outcomes. Integrated regulation had a negative association with anxiety, and intrinsic regulation had a positive association with depressive symptoms. These findings highlight the complexities of and interrelations between motivation and mental health among athletes, and support the importance of considering mental health as an outcome of motivation.

The rise of surrogacy in India over the last decade has helped individuals across the world to realize their parenting aspirations. In the macro-context of poverty in India and the hierarchical and patriarchal family set-up, concerns are expressed about coercion of women to participate in surrogacy. While the ethical issues engulfing surrogacy are widely discussed, not much is known about the role women play in the decision-making to participate in surrogacy. The paper aims to addresses this gap and is (...) based on a part of a larger ethnographic study conducted at a surrogacy clinic in Anand, Gujarat, India. We explored experiences of forty-one surrogate mothers using in-depth interviews and analysed the narratives to identify women’s own perceived role in the decision-making to participate in surrogacy. Narratives describing the decision-making process were identified and treated as a preliminary unit of analysis. We examined the use of singular and plural pronouns like “I,” “me,” and “mine” versus “we,” “us,” and “our,” along with the use of active and passive voice to determine whether women assumed responsibility for the decision to participate in surrogacy or they attributed the decision to others. Findings unravelled the complexities of the decision-making process and indicated that eighty-five percent of the women played an active role in the decision-making to participate in surrogacy, albeit with new avenues of exploitation in the commercial market space and raised serious bioethical concerns.

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

Despite their popularity, relatively scant attention has been paid to the upshot of Bayesian and predictive processing models of cognition for views of overall cognitive architecture. Many of these models are hierarchical ; they posit generative models at multiple distinct "levels," whose job is to predict the consequences of sensory input at lower levels. I articulate one possible position that could be implied by these models, namely, that there is a continuous hierarchy of perception, cognition, and action control (...) comprising levels of generative models. I argue that this view is not entailed by a general Bayesian/predictive processing outlook. Bayesian approaches are compatible with distinct formats of mental representation. Focusing on Bayesian approaches to motor control, I argue that the junctures between different types of mental representation are places where the transitivity of hierarchical prediction may be broken, and I consider the upshot of this conclusion for broader discussions of cognitive architecture.

Living systems employ several mechanisms and behaviors to achieve robustness and maintain themselves under changing internal and external conditions. Regulation stands out from them as a specific form of higher-order control, exerted over the basic regime responsible for the production and maintenance of the organism, and provides the system with the capacity to act on its own constitutive dynamics. It consists in the capability to selectively shift between different available regimes of self-production and self-maintenance in response to specific signals (...) and perturbations, due to the action of a dedicated subsystem which is operationally distinct from the regulated ones. The role of regulation, however, is not exhausted by its contribution to maintain a living system’s viability. While enhancing robustness, regulatory mechanisms play a fundamental role in the realization of an autonomous biological organization. Specifically, they are at the basis of the remarkable integration of biological systems, insofar as they coordinate and modulate the activity of distinct functional subsystems. Moreover, by implementing complex and hierarchically organized control architectures, they allow for an increase in structural and organizational complexity while minimizing fragility. Finally, they endow living systems, from their most basic unicellular instances, with the capability to control their own internal dynamics to adaptively respond to specific features of their interaction with the environment, thus providing the basis for the emergence of minimal forms of cognition.

Although the proliferation of empirical research has documented the association between parental control and school adjustment, findings of this linkage are still inconclusive. Moreover, fewer efforts have been made to address this association in middle school students. Guided by an ecological framework, the current study aimed to integrate the conflicting findings into a coherent body of knowledge, paying particular attention to two research purposes: (a) to examine the association between parental control and three objective indicators of school adjustment (...) (social competence, academic grades, and peer acceptance), and (b) to explore whether this association was moderated by individual characteristics of social identity and grit. A total of 120 Chinese middle school students (42.5% females) aged between 13 and 15 years old were recruited for this study, and research data was gathered from multiple sources. To be specific, students were asked to complete a set of self-report questionnaires concerning parental control, social identity, and grit. Meanwhile, school-related social competence was rated by head teachers; academic grades were obtained from school records; peer acceptance was assessed by sociometric nominations. The results from hierarchical regression analyses showed that parental control was negatively associated with academic grades. Moreover, when reporting higher levels of social identity, parental control was negatively related to social competence and peer acceptance for those students with lower levels of grit. Our findings suggest that parental control can dampen middle school students’ academic performance, and low levels of grit can magnify the detrimental effect of parental control on social competence and peer acceptance in middle school students who regard themselves as closely connected to social groups.
