The regulation of glucose dehydrogenase (GLD) in Drosophila illustrates the combinatorial aspects of gene regulation in development. Furthermore, the findings serve to point up a general question about cukaryotic structural gene control: is regulation of expression always optimal?

Employers seeking to control employee behavior outside of working hours is nothing new. However, recent developments have extended efforts to control employee behavior into new areas, with new significance. Employers seek to control legal behavior by employees outside of working hours, to have significant influence over employee’s health-related behavior, and to monitor and control employee’s social media, even when this behavior has nothing to do with the workplace. In this article, I draw on the work (...) of political theorists Jon Elster, Gerald Gaus and Michael Walzer, and privacy scholars Daniel Solove and Anita Allen, to show what is wrong with this extension of employer control of employee’s outside of work behavior. I argue that there are ethical limits on the controls that employers may put on their employees’ out of work behavior, and that many of these limits should be enshrined into legal protections which would prevent employers from conditioning employment on the regulations criticized. -/- (Please note that the version of this paper on SSRN is a pre-publication version.

The ability to perform movements is vital for our daily life. Our actions are embedded in a complex environment where we need to deal efficiently in the face of unforeseen events. Neural oscillations play an important role in basic sensorimotor processes related to the execution and preparation of movements. In this review, I will describe the state of the art regarding the role of motor gamma oscillations in the control of movements. Experimental evidence from electrophysiological studies has shown that (...) motor gamma oscillations accomplish a range of functions in motor control beyond merely signaling the execution of movements. However, these additional aspects associated with motor gamma oscillation remain to be fully clarified. Future work on different spatial, temporal and spectral scales is required to further understand the implications of gamma oscillations in motor control. (shrink)

Virtual enterprise is a dynamic alliance of businesses, in which multiple members undertake joint research, development, manufacturing, operation, etc. The complexity of the relationship between business members, coupled with many new technologies or methods applied in the alliance operation, leads to more uncertain factors and difficulties in the operation and risk management of the virtual enterprise. The distributed decision-making model is a fast and effective decision-making model, in which dispersed intellectual resources and information resources are dynamically integrated through virtual organization (...) forms and operating mechanisms, and the dynamic reorganization, result evaluation, and synthesis of the decision-making system are realized by certain control rules. On the basis of summarizing and analyzing previous research works, this paper expounded the research status and significance of the risk control of virtual enterprise; elaborated the development background, current status, and future challenges of distributed decision-making model; introduced the related works of decision-making variable calculation and constraint determination; constructed a risk control model for virtual enterprise based on distributed decision-making model; analyzed the multiobjective model and interval programming model of risk control; established a risk control approach for virtual enterprise based on distributed decision-making model; performed the optimal allocation of risk control funds and the selective optimization of backup allies; and finally conducted a case analysis. The study results show that, in view of the diversity of relationships between alliance businesses and the complexity of the distribution of cooperative areas, the distributed decision-making model can more reasonably describe the relationship between alliance members and accurately control the risks of virtual enterprise from multiple angles, which can effectively manage the risks of virtual enterprise. The study results of this paper provide a reference for further research on the risk control of virtual enterprise based on distributed decision-making model. (shrink)

Receptor tyrosine kinases and integrins are activated by growth factors and extracellular matrix, respectively. Their activation leads to signal transduction cascades that control many aspects of cell phenotype, including progression through the G1 phase of the cell cycle. However, the signalling cassettes driven by growth factors and matrix do not work independently of each other. Integrin triggering is essential to facilitate kinase‐ and GTPase‐mediated signals and thereby drive efficient transfer of information through the growth factor–cyclin axis. A recent (...) study indicates that an additional type of player has a key role in adhesion‐regulated control of cell cycle, namely ubiquitin ligase.(1) BioEssays 24:17–21, 2002. © 2002 John Wiley & Sons, Inc.

This book constitutes the outcome of an international conference held at the Otto-Mobes-Volkswirtschaftsschule, Graz-Stifting( Austria), from June 16 to 22, 1974. The conference was initiated by a project group working on determinants and controls of social science development at the In stitute for Advanced Studies and Scientific Research in Vienna and or ganized by the editors of this volume. It was held under the auspices of the Austrian Ministry of Science and Research. The main topics of the conference were those (...) at the forefront of the 'state of argumentation' (to borrow from one of our contributors) in philosophy and sociology of science ever since the controversy between Thomas S. Kuhn and Sir Karl R. Popper has sharpened our awareness for the methodological and substantial presuppositions involved with questions of growth and development in science. Let us give two examples of those topics. The borderline between sociology of science and philo sophy of science has become more and more unclear; while the work of at least some philosophers of science comes to have an empirical flavour, sociologists of science are increasingly apt to include logical and methodo logical components of the research process as their objects of examina tion. Papers included in this volume testify to both tendencies. (shrink)

Starting from the assumption that working memory capacity is an important predictor of general fluid intelligence, we asked which aspects of working memory account for this relationship. Two theoretical stances are discussed. The first one posits that the important explanatory factor is storage capacity, roughly defined as the number of chunks possible to hold in the focus of attention. The second one claims that intelligence is explained by the efficiency of executive control, for instance, by prepotent response inhibition. We (...) investigated 96 children at the age between 10 and 13. They completed a version of the n-back task that allows assessment of both storage capacity and inhibitory control. They also completed Raven’s Progressive Matrices as the fluid intelligence test and the Test for Creative Thinking - Drawing Production, for control purposes. We found that Raven’s scores correlated negatively with the number of unnecessary responses to irrelevant stimuli but they did not correlate with the number of signal detections. We conclude that children’s fluid intelligence depends on inhibitory control, with no relationship with storage capacity. (shrink)

Eye-tracking is increasingly studied as a cognitive and biological marker for the early signs of neuropsychological and psychiatric disorders. However, in order to make further progress, a more comprehensive understanding of the age-related effects on eye-tracking is essential. The antisaccade task requires participants to make saccadic eye movements away from a prepotent stimulus. Speculation on the cause of the observed age-related differences in the antisaccade task largely centers around two sources of cognitive dysfunction: inhibitory control (IC) and working memory (...) (WM). The IC account views cognitive slowing and task errors as a direct result of the decline of inhibitory cognitive mechanisms. An alternative theory considers that a deterioration of WM is the cause of these age-related effects on behavior. The current study assessed IC and WM processes underpinning saccadic eye movements in young and older participants. This was achieved with three experimental conditions that systematically varied the extent to which WM and IC were taxed in the antisaccade task: a memory-guided task was used to explore the effect of increasing the WM load; a Go/No-Go task was used to explore the effect of increasing the inhibitory load; a ‘standard’ antisaccade task retained the standard WM and inhibitory loads. Saccadic eye movements were also examined in a control condition: the standard prosaccade task where the load of WM and IC were minimal or absent. Saccade latencies, error rates and the spatial accuracy of saccades of older participants were compared to the same measures in healthy young controls across the conditions. The results revealed that aging is associated with changes in both IC and WM. Increasing the inhibitory load was associated with increased reaction times in the older group, while the increased WM load and the inhibitory load contributed to an increase in the antisaccade errors. These results reveal that aging is associated with changes in both IC and WM. (shrink)

Working memory (WM) is a cognitive system that allows us to select, organise, and integrate perceptual information with memories and current goal-directed intentions. As such, this system is central to day-to-day functioning and would be expected to be especially important in decision making and problem solving. We hypothesised that to the extent that individuals differ in WM capacity they would also be differentially vulnerable to the experience of depression and anxiety. Undergraduate students completed a computerised change detection task in which (...) storage capacity and filtering efficiency measures were obtained. It was found that low WM storage and poor filtering efficiency interacted to predict higher levels of emotional distress as measured by self-reported depressive symptoms, ruminative coping, and state anxiety. It was suggested that low capacity and a poor ability to ignore task-irrelevant information may lead to poorer problem solving, more extreme judgements of oneself and circumstances, increased rumination, and poorer emotional regulation.

SummaryThis paper explicates a Constructivist Epistemology which underlies cybernetic models of perceiving and knowing. We focus on the recent work of W. T. Powers . Powers' model consists of hierarchially arranged negative feedback systems, is based on the claim that living organisms behave to control perceptions, and thus suggests that organisms construct their experiential world. We argue that this provides a basis for a modified scientific scepticism, a scepticism with a positive dimension gained by adding the notion of (...) cognitive construction. From this perspective, knowing and perceiving pertain to the construction of invariances in the living organism's experience.RésuméDans cet essai, nous exposons une épistémologie constructivistc qui sert de base pour des modèles cybernétiques de la perception et de la connaissancc. Nous nous référonts à l'œuvre de W. T. Powers qui a propose un modèle constitué par un arrangement hiérarchique de boucles rétroactives en partant de l'idée que tout comportement a pour but de contrôler les perceptions. Ce modèle suggère que le monde expérientiel est le produit d'une activité constructive. Nous défendons la thèse que cette orientation peut fournir le fondement d'un scepticisme scientifique qui acquiert un aspect positif par la notion de construction cognitive. De ce point de vue, connaissance et perception sont des activités qui construisent des invariances dans l'expérience d'un organisme.ZusammenfassungIn der vorliegenden Arbeit wird eine konstruktivistische Erkenntnistheorie entwickelt, die ihrerseits gewissen kybernetischen Modeller) der Wahrnehmurtg und Er‐kenntnis zugrundeliegt.

Immigrant nurses make up a large percentage of the Australian nursing workforce. Since the support in the workplace is expected to be inclusive for all nurses, the aim of this article is to explore how support and opportunities for professional growth, learning and development are distributed across different categories of nurses working in a neonatal intensive care unit (NICU). An ethnographic approach has opened an examination of the everyday workplace practices in the NICU to gain insight into how nurses made (...) sense of the social and power relations occurring between themselves and their senior colleagues and how they experienced the support and opportunities they received in their workplace. As today's workplaces such as the NICU are diverse in races, culture and experiences, the concepts of intersectionality and cultural safety assisted in identifying inequality and injustice related to such diversity. The results showed how patronage relations rendered nurses with immigrant status with major disadvantage and left them clinically and culturally vulnerable. Such inequity defeats the reasons for encouraging skilled migration of nurses and poses questions on the cultural competency of recruiting organisations. Considering how cultural safety might guide staff development offers opportunities for authentic support to culturally diverse nurses. (shrink)

Gray's neuropsychological model of consciousness uses a hierarchical feedback loop framework that has been extensively discussed by many others in psychology. This commentary therefore urges Gray to integrate with, or at least acknowledge previous models. It also points out flaws in his feedback model and suggests directions for further theoretical work.

This work examines the development and performance of federal independent regulatory bodies in Canada in the period up to 1979, with particular attention to the operation of legislative schemes that include executive review and appeal powers. The author assesses the impact of the exercise of these powers on the administrative law process, and proposes new models for the generation, interpretation, implementation, review, and enforcement of regulatory policy. The study includes a series of representative case studies based on documentation and (...) extensive interviews with individuals drawn from government, agencies, and other parties, including counsel for public interest groups. This enables author, writing from her experience as a participant-observer embedded in the public interest legal sector, to draw on the experiences and perspectives of a broad range of participants in the regulatory process, including but not limited to those dealing with the regulated energy, transportation, communications, and foreign investment sectors. Legal principles identified as emergent in leading judicial decisions in administrative law are used to assess the powers and practices used in executive reviews and appeals. The author finds those powers and practices to be flawed and proposes changes. The proposed models are designed to accord with emerging legal principles and avoid flaws of the types identified in the review and appeal provisions. This work, written under contract with the Administrative Law Project of the Law Reform Commission of Canada, formed one part of a comprehensive study of administrative law at the federal level in Canada.

Prior research has identified age 9–11 as a critical period for the development of the control-of-variables strategy (CVS). We examine the stability of interindividual differences in children's CVS skills with regard to their precursor skills during this critical developmental period. To this end, we relate two precursor skills of CVS at age 9 to four skills constituting fully developed CVS more than 2 years later, controlling for children's more general cognitive development. Note thatN= 170 second- to fourth-graders worked on (...) multiple choice-assessments of their understanding of indeterminacy of evidence and of confounding. We find relations between these two precursor skills and children's CVS skills 2 years later at age 11 inplanning, identifying, andinterpretingcontrolled experiments, and in recognizing the inconclusiveness of confounded comparisons (understanding). In accordance with the perspective that both indeterminacy and confounding constitute critical, related yet distinct elements of CVS, both precursor skills contribute to the prediction of later CVS. Together, the two precursor skills can explain 39% of students' later CVS mastery. Overall, the understanding of indeterminacy is a stronger predictor of fully developed CVS than that of confounding. The understanding of confounding, however, is a better predictor of the more difficult CVS sub-skills of understanding the inconclusiveness of confounded comparisons, and of planning a correctly controlled experiment. Importantly, both precursor skills maintain interactive predictive strength when controlling for children's general cognitive abilities and reading comprehension, showing that the developmental dynamics of CVS and its precursor skills cannot be fully ascribed to general cognitive development. We discuss implications of these findings for theories about the development of CVS and broader scientific reasoning. (shrink)

Investigation of joint torque constraint compliance is of significance for robot manipulators especially working in complex environments. A lot of which is attributed to that, on the one hand, it is beneficial to the improvement of both safety and reliability of the mission execution. On the other hand, the energy consumption required by the robot to complete the desired mission can be reduced. Most existing schemes do not take the joint torque limit and other inherent physical structure limits in a (...) manipulator into account at the same time. In addition, many unavoidable uncertainties such as the external environmental disturbance and/or electromagnetism interferences in the circuit system may influence the accuracy and effectiveness of the task execution for a robot. In this study, we cast light on the acceleration level control of redundant robot manipulators considering both four physical constraint limits and interference rejection. A robust unified quadratic-programming-based hybrid control scheme is proposed, where the joint torque constraints are converted as two inequality constraints based on the robots’ dynamics equation. A recurrent-neural-network-based controller is designed for solving the control variable. Numerical experiments performing in PUMA 560 manipulator and planer manipulator illustrate that a rational torque distribution is obtained among the joints and the considered physical structural vectors are all restricted to the respective constraint range. In addition, even disturbed by the noise, the manipulator still successfully tracks the desired trajectory under the proposed control scheme. (shrink)

This paper is devoted to the control problem of a nonlinear dynamical system obtained by a truncation of the two-dimensional Navier–Stokes equations with periodic boundary conditions and with a sinusoidal external force along the x-direction. This special case of the 2D N-S equations is known as the 2D Kolmogorov flow. Firstly, the dynamics of the 2D Kolmogorov flow which is represented by a nonlinear dynamical system of seven ordinary differential equations of a laminar steady state flow regime and a (...) periodic flow regime are analyzed; numerical simulations are given to illustrate the analysis. Secondly, an adaptive controller is designed for the system of seven ODEs representing the approximation of the dynamics of the 2D Kolmogorov flow to control its dynamics either to a steady-state regime or to a periodic regime; the value of the Reynolds number is determined using an update law. Then, a static sliding mode controller and a dynamic sliding mode controller are designed for the system of seven ODEs representing the approximation of the dynamics of the 2D Kolmogorov flow to control its dynamics either to a steady-state regime or to a periodic regime. Numerical simulations are presented to show the effectiveness of the proposed three control schemes. The simulation results clearly show that the proposed controllers work well. (shrink)

This paper offers a conceptual framework which (re)integrates goal-directed control, motivational processes, and executive functions, and suggests a developmentalpathway from situated action to higher level cognition. We first illustrate a basic computational (control-theoretic) model of goal-directed action that makes use of internalmodeling. We then show that by adding the problem of selection among multiple actionalternatives motivation enters the scene, and that the basic mechanisms of executivefunctions such as inhibition, the monitoring of progresses, and working memory, arerequired for this (...) system to work. Further, we elaborate on the idea that the off-line re-enactment of anticipatory mechanisms used for action control gives rise to (embodied)mental simulations, and propose that thinking consists essentially in controlling mental simulations rather than directly controlling behavior and perceptions. We concludeby sketching an evolutionary perspective of this process, proposing that anticipationleveraged cognition, and by highlighting specific predictions of our model. (shrink)

In previous works, I defined ourselves as informational organisms, or inforgs for short, who forage for, produce, cultivate, curate, process, and consume information (Floridi 2013). Yet, we may also be understood as interfaces, who inhabit and interact with, an environment also made up of data and computational processes. By describing ourselves in such terms, this paper argues that we can better understand several crucial phenomena that characterise our digital age, including marketing and the “marketisation” of political communication. The article concludes (...) by discussing some of the implications for this in political theory. -/- . (shrink)

Can suggestion, particularly hypnotic suggestion, influence cognition? Addressing this intriguing question experimentally is on the rise in cognitive research, nowhere more prevalently than in the domain of cognitive control and attention. This may well rest on the intuitive connection between hypnotic suggestion and attention, where the hypnotist controls the subject’s attention. Particularly impressive has been the work of Raz and his colleagues demonstrating the modulation and even the complete elimination of classic Stroop color–word interference when subjects are given (...) a posthypnotic suggestion that words are meaningless. Overriding a highly practiced, possibly even automatic response like reading is testament to the attentional control that can be exerted under hypnotic suggestion. What else do we need to know—in the Stroop context and more broadly—to obtain a clear picture of how suggestion can orchestrate attention? (shrink)

Reclamation is the phenomenon of an oppressed group repurposing language to its own ends. A case study is reclamation of slur words. Popa-Wyatt and Wyatt (2018) argued that a slurring utterance is a speech act which performs a discourse role assignment. It assigns a subordinate role to the target, while the speaker assumes a dominant role. This pair of role assignments is used to oppress the target. Here I focus on how reclamation works and under what conditions its benefits can (...) stabilise. I start by reviewing the data and describing preconditions and motivations for reclamation. Can reclamation be explained in the same basic framework as regular slurring utterances? I argue that it can. I also identify some features that must be a prediction of any theory of reclamation. I conclude that reclamation is an instance of a much broader class of acts we do with words to change the distribution of power: it begets power, but it also requires it. (shrink)

Most accounts of mechanism discovery have focused on mechanisms that perform the work required to produce a phenomenon. These mechanisms are often subject to regulation by control mechanisms. Using the example of the molecular motor dynein, this paper examines one process by which such control mechanisms are discovered—the process by which researchers, after identifying additional components required to produce the phenomenon but not directly involved in the work of producing that phenomenon, investigate both how these components (...) act on the original mechanism and how they do so in response to measurements of conditions relevant to the operation of the controlled mechanism.

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)

A number of studies have demonstrated pragmatic language difficulties in people with Schizophrenia Spectrum and Other Psychotic Disorders. However, research about how people with schizophrenia spectrum and other psychotic disorders understand scalar implicatures is surprisingly rare, since SIs have generated much of the most recent literature. Scalar implicatures are pragmatic inferences, based on linguistic expressions like some, must, or, which are part of a scale of informativeness. Logically, the less informative expressions imply the more informative ones, but pragmatically people usually (...) infer that the presence of a less informative term implies that the more informative term was not applicable. In one of the few existing studies with people with schizophrenia spectrum and other psychotic disorders, Wampers et al. observed that in general, people with schizophrenia spectrum and other psychotic disorders were less likely to derive SIs than controls. The current study has three main aims. First, we want to replicate the original finding with the scalar terms some-all. Second, we want to investigate how these patients deal with different scalar terms, that is, we want to investigate if scalar diversity is also observed in this clinical group. Third, we investigate the role of working memory, often seen as another important mechanism to enable inferring SIs. Twenty-one individuals with a psychotic disorder and 21 matched controls answered 54 under-informative statements, in which seven different pairs of scalar terms were used. In addition, working memory capacity was measured. Patients with schizophrenia spectrum and other psychotic disorders did not make more logical interpretations when processing quantifiers, disconfirming Wampers et al.. However, certain scalar scales elicited more pragmatic interpretations than others, which is in line with the scalar diversity hypothesis. Additionally, we observed only partial evidence for the role of working memory. Only for the scalar scale and-or, a significant effect of working memory was observed. The implications of these results for patients with schizophrenia spectrum and other psychotic disorders are discussed, but also the role of working memory for pragmatic inferences, as well as the place of SIs in experimental pragmatics.

Beyond the reaches of scholarly debates about how to define and value civility properly, social actors across various institutional domains routinely demarcate civil from uncivil behavior. Yet this everyday classification process remains understudied and undertheorized, despite being widespread and having significant stakes for the individuals and groups involved. This article begins to fill this gap by developing the concept of civility contests—practical efforts to draw symbolic boundaries between civil and uncivil individuals, groups, or behaviors. Through a focus on the realm (...) of political protest in the United States, this article demonstrates that civility contests involve a wide range of political actors (including institutionalized power holders, opposing movements, and the media) who engage in this boundary-work in order to justify the control or (de)legitimation of protest. It then highlights patterned disparities in the outcomes of these contests, demonstrating that the likelihood of being marked as uncivil and the extent to which this prompts negative social sanction is shaped by one’s social position. Overall, the article seeks to stimulate and guide future empirical research on civility contests and to deepen theoretical understandings of the relationship between symbolic and social boundaries and the role of symbolic boundary-work in the reproduction of political inequality.

Due to the frequent occurrence of ethical transgressions and unethical employee behaviors, there has lately been an increasing interest in the ethical foundations of contemporary organizations. However, large-scale comprehensive analyses of organizational ethics are still comparatively limited. Our study contributes to both management control and business ethics literature by empirically examining potential antecedents as well as resulting effects of ethical work climates on organizational-level outcomes. Based on a cross-sectional survey among 295 large- and medium-sized companies, we find that (...) more informal means of control constitute important elements of a broader organizational control context that are strongly related to the emergence of coherent ethical work climates with an increased awareness of ethical issues. Moreover, our results show that the relationship between ethical work climates and organizational performance can be considered as rather indirect as it is fully mediated by increased mutual trust among employees. Overall, our study thus supports the particular importance of ethical work climates and identifies appropriate means to encourage ethical conduct. (shrink)

Social cognition differs from general cognition in its focus on understanding, perceiving, and interpreting social information. However, we argue that the significance of domain‐general processes for controlling cognition has been historically undervalued in social cognition and social neuroscience research. We suggest much of social cognition can be characterized as specialized feature representations supported by domain‐general cognitive control systems. To test this proposal, we develop a comprehensive working model, based on an interactive activation and competition architecture and applied to the (...) control of action. As such, we label the model “ICON” (interactive activation and competition model for the control of action). We used the ICON model to simulate human performance across various laboratory tasks. Our simulations emphasize that many laboratory‐based social tasks do not require socially specific control systems, such as those that are argued to rely on neural networks associated with theory‐of‐mind. Moreover, our model clarifies that perceived disruptions in social cognition, even in what appears to be disruption to the control of social cognition, can stem from deficits in social representation instead. We advocate for a “default stance” in social cognition, where control is usually general, but representation is specific. This study underscores the importance of integrating social cognition within the broader realm of domain‐general control processing, offering a unified perspective on task processing. (shrink)

Cancer chemotherapy has been the most common cancer treatment. However, it has side effects that kill both tumor cells and immune cells, which can ravage the patient’s immune system. Chemotherapy should be administered depending on the patient’s immunity as well as the level of cancer cells. Thus, we need to design an efficient treatment protocol. In this work, we study a feedback control problem of tumor-immune system to design an optimal chemotherapy strategy. For this, we first propose a (...) mathematical model of tumor-immune interactions and conduct stability analysis of two equilibria. Next, the feedback control is found by solving the Hamilton–Jacobi–Bellman equation. Here, we use an upwind finite-difference method for a numerical approximate solution of the HJB equation. Numerical simulations show that the feedback control can help determine the treatment protocol of chemotherapy for tumor and immune cells depending on the side effects. (shrink)

The article discusses the conflict between lived religion and the state control of poor relief in a modernizing society by analysing the case of Emma Mäkinen’s private orphanage. Emma Mäkinen’s philanthropic work among neglected children was motivated by her Evangelical Revivalist conviction. Because of her trust in the transformative power of faith, she considered it appropriate to establish an orphanage next to a shelter for ‘fallen’ women. This decision led her onto a collision course with the State Inspector (...) of Poor Relief and the general public, who did not share her religious views but emphasized the legislative and moral aspects vis-à-vis organizing social work. The conflict demonstrates, firstly, how the ancien régime and the traditional religious authority of the Evangelical Lutheran state church in particular was challenged by individual agency in voluntary associations such as the Evangelical Revivalist Free Mission. Secondly, the case of Emma Mäkinen’s orphanage reflects how new kinds of boundaries were created by the encroaching of state control into the sphere of private philanthropy, followed by the strengthening role of scientific theories and nationalistic thinking in social work. Thirdly, the conflict opens up a view on border-crossings, thus emphasizing the undefined nature of a modernizing society. (shrink)

The ability to reason independently from one's own goals or beliefs has long been recognised as a key characteristic of the development of formal operational thought. In this article we present the results of a study that examined the correlates of this ability in a group of 10-year-old children ( N = 61). Participants were presented with conditional and relational reasoning items, where the content was manipulated such that the conclusion to the arguments were either congruent, neutral, or incongruent with (...) beliefs, and either logically valid or logically invalid. Participants also received a measure of working memory capacity (the counting span task) and a measure of inhibitory control (the stop signal task). Indices of belief bias and logical reasoning on belief-based problems were predicted independently by both measures. In contrast logical reasoning on belief neutral problems was predicted by working memory alone. The findings suggest that executive functions play a key role in the development of children's ability to decontextualise their thinking. (shrink)

Recently it has become clear that integrins and other adhesive receptors play an important role in the control of cell growth and differentiation. In various cell types, anchorage to the extracellular matrix via integrins strongly influences the ability of the cell to respond to soluble mitogens or to differentiation factors. Thus adhesive receptors must generate signals that influence cell behavior. Some of the pathways of adhesion receptor signaling are now beginning to be worked out, but there is still much (...) to learn. In particular, the mechanistic basis for the cooperation between anchorage signals and signals from soluble growth and differentiation factors remains ill‐defined. This review will examine some of the current information linking adhesion receptors to control of mitogenesis and differentiation. (shrink)
