Feedback encompasses different aspects of learning and enables students tofocus on the goal of the lesson while being conscious of their responsibility fortheir success. It should neither be strictly criticism, nor mere praise; rather, itshould contain a set of information that will guide them in correcting their mistakesand learning. Feedback has a positive impact on student learning (Voerman et al.,2012) and is a key factor in increasing mathematical achievement (Clarke, 2001).The purpose of this action research is (...) to improve elementary mathematics teachingthrough the provision of feedback. Analysis of the video recordings from the lessonsrevealed the prevalence of feedback aimed at assessing students’ comprehensionand achievement. Additionally, students received feedback on the assignment. Asthe planned activities were implemented, an increase in student motivation, controlover their own learning and student satisfaction was also observed. The findingsdemonstrate that it is possible to improve mathematics education by introducingchanges that align with for the students’ abilities and interests. In doing so, it iscrucial for teachers to be knowledgeable about effective teaching methods thatmust be adapted to the educational context in which they work. (shrink)

The spontaneous organization of collective activities in animal groups and societies has attracted a considerable amount of attention over the last decade. This kind of coordination often permits group‐living species to achieve collective tasks that are far beyond single individuals' capabilities. In particular, a key benefit lies in the integration of partial knowledge of the environment at the collective level. In this contribution, we discuss various self‐organization phenomena in animal swarms and human crowds from the point of view of (...) class='Hi'>information exchange among individuals. In particular, we provide a general description of collective dynamics across species and introduce a classification of these dynamics not only with respect to the way information is transferred among individuals but also with regard to the knowledge processing at the collective level. Finally, we highlight the fact that the individual’s ability to learn from past experiences can have a feedback effect on the collective dynamics, as experienced with the development of behavioral conventions in pedestrian crowds.

This 1992 book examines alternative methods for achieving optimality without all the apparatus of economic planning, or a vain reliance on sufficiently 'perfect' competition. All rely entirely on the self-interest of economic agents and voluntary contract. The author considers methods involving feedback iterative controls which require the prior selection of a 'criterion function', but no prior calculation of optimal quantities. The target is adjusted as the results for each step become data for the criterion function. Implementation is built in (...) by the incentive structure, and all controls rely on consistency with the self-interest of individuals. The applicability of all the methods is shown to be independent of the form of ownership of enterprises: examples are given for industries which are wholly privately owned, wholly nationalized, mixed and labour-managed.

The primary goal of the peer review of research grant proposals is to evaluate their quality for the funding agency. An important secondary goal is to provide constructive feedback to applicants for their resubmissions. However, little is known about whether review feedback achieves this goal. In this paper, we present a multi-methods analysis of responses from grant applicants regarding their perceptions of the effectiveness and appropriateness of peer review feedback they received from grant submissions. Overall, 56–60% of (...) applicants determined the feedback to be appropriate, although their judgments were more favorable if their recent application was funded. Importantly, independent of funding success, women found the feedback better written than men, and more white applicants found the feedback to be fair than non-white applicants. Also, perceptions of a variety of biases were specifically reported in respondents’ feedback. Less than 40% of applicants found the feedback to be very useful in informing their research and improving grantsmanship and future submissions. Further, negative perceptions of the appropriateness of review feedback were positively correlated with more negative perceptions of feedback usefulness. Importantly, respondents suggested that highly competitive funding pay-lines and poor inter-panel reliability limited the usefulness of review feedback. Overall, these results suggest that more effort is needed to ensure that appropriate and useful feedback is provided to all applicants, bolstering the equity of the review process and likely improving the quality of resubmitted proposals.

When people communicate, they coordinate a wide range of linguistic and non-linguistic behaviors. This process of coordination is called alignment, and it is assumed to be fundamental to successful communication. In this paper, we question this assumption and investigate whether disalignment is a more successful strategy in some cases. More specifically, we hypothesize that alignment correlates with task success only when communication is interactive. We present results from a spot-the-difference task in which dyads of interlocutors have to decide whether they (...) are viewing the same scene or not. Interactivity was manipulated in three conditions by increasing the amount of information shared between interlocutors. We use recurrence quantification analysis to measure the alignment between the scan-patterns of the interlocutors. We found that interlocutors who could not exchange feedback aligned their gaze more, and that increased gaze alignment correlated with decreased task success in this case. When feedback was possible, in contrast, interlocutors utilized it to better organize their joint search strategy by diversifying visual attention. This is evidenced by reduced overall alignment in the minimal feedback and full dialogue conditions. However, only the dyads engaged in a full dialogue increased their gaze alignment over time to achieve successful performances. These results suggest that alignment per se does not imply communicative success, as most models of dialogue assume. Rather, the effect of alignment depends on the type of alignment, on the goals of the task, and on the presence of feedback. (shrink)

This paper proposes an agent community based information retrieval method, which uses agent communities to manage and look up information related to users. An agent works as a delegate of its user and searches for information that the user wants by communicating with other agents. The communication between agents is carried out in a peer-to-peer computing architecture. In order to retrieve information related to a user query, an agent uses two histories : a query/retrieved document history(Q/RDH) (...) and a query/sender agent history(Q/SAH). The former is a list of pairs of a query and retrieved documents, where the queries were sent by the agent itself. The latter is a list of pairs of a query and sender agents and shows ``who sent what query to the agent''. This is useful to find a new information source. Making use of the Q/SAH is expected to cause a collaborative filtering effect, which gradually creates virtual agent communities, where agents with the same interests stay together. Our hypothesis is that a virtual agent community reduces communication loads to perform a search. As an agent receives more queries, then more links to new knowledge are achieved. From this behavior, a ``give and take''(or positive feedback) effect for agents seems to emerge. We implemented this method with Multi-Agents Kodama which has been developed in our laboratory, and conducted preliminary experiments to test the hypothesis. The empirical results showed that the method was much more efficient than a naive method employing 'broadcast' techniques only to look up a target agent. (shrink)

The problem of knowledge has been centred around the study of the content of our consciousness, seeing the world through internal representation, without any satisfactory account of the operations of nature that would be a pre-condition for our own performances in terms of concept efficiency in organizing action externally. If we want to better understand where and how meaning fits in nature, we have to find the proper way to decipher its organization, and account for the fact that we have (...) found codes and replicators operating at a deep levels of analysis. Informational analysis deals with units of organizational stability but it takes them for granted and leaves open the question of their origin. Patterns are used when we recognize the same configurations at different places and try to explain through their recurrence, yet to make sense of the presence of signals and counter-balancing mechanisms disseminated in nature, a hypothesis is offered to the effect that feedback signals would have a role to play in the coming about of a world that is open to new configurations and submitted to a form of stability that is more attuned to system laws than overarching unrevisable ones.

Alternative Learning System (ALS) has been adopted in Philippine basic education, yet there is no academic institution in the region prepares ALS teachers in teaching life skills. ALS teachers graduated from different programs of teacher education for formal education. In response, an extension project was conceptualized and implemented to enhance the teaching capacity and effectiveness of ALS teachers. Case study was conducted to evaluate the effectiveness of the project. It explored the transfer of life skills among ALS teachers. Data were (...) collected from multiple sources. Interview and written responses, and feedbacks were analyzed using thematic narrative analysis. Other data were analyzed using document and descriptive analyses. The project had achieved its objectives and rated best by participants. These indicate that the project was implemented effectively and successfully. ALS teachers have acquired life skills and transferred them to others. Thus, the project has made a difference in the lives of these teachers. (shrink)

The use of the capability approach as an evaluative tool for Information and Communication Technology (ICT) policy and programs in developing countries, in particular at a grass-roots community level, is an emerging field of application. However, one of the difficulties with ICT for development (ICT4D) evaluations is in linking what is often no more than a resource, for example basic access, to actual outcomes, or means to end. This article argues that the capability approach provides a framework for evaluating (...) the strength of this linkage and that the latter is a key determinant of whether or not communities sustain ICT4D programs beyond the initial start-up phase. The argument is made by describing an evaluative application of the capabilities approach to community ICT4D programs using two Indigenous community case studies conducted in Cape York, in the far north-east of Australia. Key to the evaluative approach is the identification of community defined, context specific concepts of well-being and constitutive valued functionings and the derivation from this of required capabilities. This move away from normative definitions of capabilities or capability types to a definition that reflects the Indigenous culture, history, circumstances, and well-being aspirations of each community is intended to give a voice to the people and at the same time provide a deeper informational base—through narrative—for policy and program design than has previously been available. The article concludes that by operationalising the capability approach in a context and purpose specific way, policy and program design can be improved so as to include more communities on the margin and thereby achieve more socially inclusive ICT based development. A process is also outlined for using the evaluative application of the capability approach for community ICT4D within a policy feedback loop. (shrink)

_2020 PROSE Award Winner, Education Theory Category 2019 Outstanding Academic Title, _Choice_ In _Where Teachers Thrive_, Susan Moore Johnson outlines a powerful argument about the importance of the school as an organization in nurturing high‐quality teaching._ Based on case studies conducted in fourteen high-poverty, urban schools, the book examines why some schools failed to make progress, while others achieved remarkable results. It explores the challenges that administrators and teachers faced and describes what worked, what didn’t work, and why. Johnson draws (...) on vivid portraits of schools to highlight an array of school‐based systems and practices that support teachers’ professional growth and effectiveness. These include a rich and interactive hiring process; team‐based curriculum planning and assessment; and informative feedback and ongoing professional learning. Critical to all of these is the role of the principal as an essential agent in a school’s success. Although these elements may vary from school to school, Johnson argues that together these systems provide a comprehensive, mutually reinforcing set of well-orchestrated strategies that can help schools deliver results that exceed the sum of teachers’ individual efforts. Since 2000, policy makers and education officials have diligently sought to improve schools by improving the quality of individual teachers. However, even if those teachers are skilled and committed, the schools where they work are all too often disjointed, dysfunctional organizations that serve no one well. _Where Teachers Thrive _explains clearly how educators within a school can join together to adopt systems of practice that ensure growth and success by all teachers and their students.

A central principle of bioethics is “subject autonomy,” the acknowledgement of the primacy of the informed consent of the subject of research. Autonomy requires informed consent — the assurance that the research participant is informed about the possible risks and benefits of the research. In fact, informed consent is difficult when a single drug is being tested, although subjects have a baseline understanding of the testing of a pharmacological agent and the understanding that they can stop taking the drug if (...) there were an adverse event. However, informed consent is even less easily achieved in the modern arena of complex new molecular and cellular therapies. In this article, we argue that as science confronts new issues such as transplantation of stem cell products, which may live within the participant for the rest of their lives, researchers must carefully consider and constantly re-examine how they properly inform subjects considering participation trials of these novel therapeutic strategies.For example, the manufacture of a vial of a cell product that consists of a collection of growing cells is very different than the production of a vial of identical pills, which can be presumed to be identical. The scientific concepts on which these cellular approaches are based may seem alien and incomprehensible to a research subject, who thinks of a clinical trial as simply the selection and testing of the most efficacious pharmaceutical agent already proven to work in preclinical animal studies. The research subject would be wrong. (shrink)

Most agree that, if all else is equal, patients should be provided with enough information about proposed medical therapies to allow them to make an informed decision about what, if anything, they wish to receive. This is the principle of informed choice; it is closely related to the notion of informed consent. Contemporary clinical trials are analysed according to classical statistics. This paper puts forward the argument that classical statistics does not provide the right sort of information for (...) informing choice. The notion of probability used by classical statistics is complex and difficult to communicate. Therapeutic decisions are best informed by statistical approaches that assign probabilities to hypotheses about the benefits and harms of therapies. Bayesian approaches to statistical inference provide such probabilities. (shrink)

Dynamic body feedback is used in dance movement therapy, with the aim to facilitate emotional expression and a change of emotional state through movement and dance for individuals with psychosocial or psychiatric complaints. It has been demonstrated that moving in a specific way can evoke and regulate related emotions. The current study aimed to investigate the effects of executing a unique set of kinetic movement elements on an individual mover’s experience of happiness. A specific sequence consisting of movement elements (...) that recent studies have related to the feeling of happiness was created and used in a series of conditions. To achieve a more realistic reflection of DMT practice, the study incorporated the interpersonal dimension between the dance movement therapist and the client, and the impact of this interbodily feedback on the emotional state of the client. This quantitative study was conducted in a within-subject design. Five male and 20 female participants participated in three conditions: a solo executed movement sequence, a movement sequence executed with a DMTh who attuned and mirrored the movements, and a solo executed movement sequence not associated with feelings of happiness. Participants were only informed about the movements and not the feelings that may be provoked by these movements. The effects on individuals were measured using the Positive and Negative Affect Schedule and visual analog scales. Results showed that a specific movement sequence based on movement elements associated with happiness executed with a DMTh can significantly enhance the corresponding affective state. An additional finding of this study indicated that facilitating expressed emotion through movement elements that are not associated with happiness can enhance feelings such as empowerment, pride, and determination, which are experienced as part of positive affect. The results show the impact of specific full-body movement elements on the emotional state and the support outcome of DMT on emotion regulation. (shrink)

Top-down feedback does not benefit speech recognition; on the contrary, it can hinder it. No experimental data imply that feedback loops are required for speech recognition. Feedback is accordingly unnecessary and spoken word recognition is modular. To defend this thesis, we analyse lexical involvement in phonemic decision making. TRACE (McClelland & Elman 1986), a model with feedback from the lexicon to prelexical processes, is unable to account for all the available data on phonemic decision making. The (...) modular Race model (Cutler & Norris 1979) is likewise challenged by some recent results, however. We therefore present a new modular model of phonemic decision making, the Merge model. In Merge, information flows from prelexical processes to the lexicon without feedback. Because phonemic decisions are based on the merging of prelexical and lexical information, Merge correctly predicts lexical involvement in phonemic decisions in both words and nonwords. Computer simulations show how Merge is able to account for the data through a process of competition between lexical hypotheses. We discuss the issue of feedback in other areas of language processing and conclude that modular models are particularly well suited to the problems and constraints of speech recognition. Key Words: computational modeling; feedback; lexical processing; modularity; phonemic decisions; reading; speech recognition; word recognition. (shrink)

The common conception of intelligence in terms of information processing has its origin in cybernetics and information technology. Its import into cognitive science and the humanities not only generates theoretical problems, but also constitutes the basis of methods and policies that have adverse impacts on intelligent agents. In order to demonstrate why this technological conception of intelligence is not suitable for addressing the intelligence of living agents, and why natural intelligence is artificially not imitable, first, the basic notions, (...) formalisms, and assumptions of the technological context are presented. Next, the cybernetic feedback scheme is modified by dropping the technological assumptions, and a more sophisticated closed-loop scheme is developed that is better suited for representing cognitive processes in living agents. With reference to the thus developed scheme, the capacity of achieving ontological expansion, via what will be called “internal restructuring,” is proposed as the criterion for intelligence.

Practical wisdom (hereafter simply “wisdom”) is the intellectual virtue that enables a person to make reliably good decisions about how, all-things-considered, to live and conduct herself. Because wisdom is such an important and high-level achievement, we should wonder: what is the nature of wisdom? What kinds of skills, habits and capacities does it involve? Can real people actually develop it? If so, how? I argue that we can answer these questions by modeling wisdom on expert decision-making skill in complex (...) areas like firefighting. I develop this expert skill model of wisdom using philosophical argument informed by relevant empirical research. I begin in Chapter 1 by examining the historical roots of analogies between wisdom and practical skills in order to motivate the expert skill model. In Chapter 2, I provide the core argument for the expert skill model. I then use the remaining chapters to pull out the implications of the expert skill model. In Chapter 3, I show that the expert skill model yields practical guidance about how to develop wisdom. In Chapter 4, I address the objection, due to Daniel Jacobson, that wisdom is not a skill that humans could actually develop, since skill development requires a kind of feedback in practice that is not available for all-things-considered decisions about how to live. Finally, in Chapter 5, I apply the expert skill model to the question, much discussed by virtue ethicists, of whether a wise person deliberates using a comprehensive and systematic conception of the good life.

The concept of sustainability was developed in response to stakeholder demands. One of the key mechanisms for engaging stakeholders is sustainability disclosure, often in the form of a report. Yet, how reporting is used to engage stakeholders is understudied. Using resource dependence and stakeholder theories, we investigate how companies within the same industry address different dependencies on stakeholders for economic, natural environment, and social resources and thus engage stakeholders accordingly. To achieve this objective, we conducted our research using qualitative research (...) methods. Our findings suggest that the resource dependencies on different stakeholders lead to development of different stakeholder relationships and thus appropriate resources within the company to execute engagement strategies that are informing, responding, or involving. Our research explains why diversity exists in sustainability disclosure by studying how it is used to engage stakeholders. We find that five sustainability reporting characteristics are associated with the company’s stakeholder engagement strategy: directness of communication, clarity of stakeholder identity, deliberateness of collecting feedback, broadness of stakeholder inclusiveness, and utilization of stakeholder engagement for learning. Our study develops the literature by providing insight into companies’ choices of stakeholder engagement strategy thus explaining diversity in sustainability reporting based on the characteristics and relationships with specific stakeholders.

The social trackways theory is centered on the remarkable 3.66 mya Laetoli Fossilized Trackways, for they incontrovertibly reveal our ancestors were already obligate bipeds with very human-like feet, and were intentionally stepping in other band members’ footprints to maintain safe footing. Trackways are unique among natural sign systems in possessing a depictive narratively generative structure, somewhat like the symbolic sign systems of gestural languages. Therefore, due to daily embodied reiteration of their own and other band member’s old footprints, both for (...) bipedal safety and as recognizable wayfinding markers for socio-ecological navigation, incrementally our Mid-Pliocene ancestors began to acquire a cognitive capacity for episodic personal memories and episodic future simulations. They began mentally representing themselves as intentional agents continuously travelling from the past into the future. This spatially and temporally self-projecting awareness manifested itself as extra theory of mind and mental space-and-time-travel capacities, which increasingly enabled intentional or conscious, top-down executive adjustment of past behaviors for the sake of achieving better ways of doing things in the future. Future-directed behavioral and cultural adaptations began to increase fitness in all domains, thus creating powerful selective feedback for further entrenchment. Here we focus on overtly or consciously intentional exploratory wayfinding and transmission of elsewhere-and-when information, using pragmatic, discursive modes of communication, which enabled far more cooperative and efficient foraging practices. Selection for better communication thus led to intentional trail marking and the earliest emergence of more conventional/symbolic depictive and gestural “protolanguages.”. (shrink)

The strategies of action employed by a human subject in order to perceive simple 2-D forms on the basis of tactile sensory feedback have been modelled by an explicit computer algorithm. The modelling process has been constrained and informed by the capacity of human subjects both to consciously describe their own strategies, and to apply explicit strategies; thus, the strategies effectively employed by the human subject have been influenced by the modelling process itself. On this basis, good qualitative and (...) semi-quantitative agreement has been achieved between the trajectories produced by a human subject, and the traces produced by a computer algorithm. The advantage of this reciprocal modelling option, besides facilitating agreement between the algorithm and the empirically observed trajectories, is that the theoretical model provides an explanation, and not just a description, of the active perception of the human subject.

ABSTRACT Genomic research and biobanking present several ethical, social and cultural challenges, particularly when conducted in settings with limited scientific research capacity. One of these challenges is determining the model of consent that should support the sharing of human biological samples and data in the context of international collaborative research. In this paper, we report on the views of key research stakeholders in Ghana on what should count as good ethical practice when seeking consent for genomic research and biobanking in (...) Africa. This study was part of a multi-country qualitative case study conducted in three African countries: Ghana, Uganda and Zambia under the auspices of the Human Heredity and Health in Africa initiative (H3Africa). Our study suggests that while participants are willing to give consent for their samples and associated data to be used for future research purposes, they expect to receive feedback about the progress of the research and about the kinds of research being undertaken on their samples and data. These expectations need to be anticipated and discussed during the consent process which should be seen as part of an ongoing communication process throughout the research process. (shrink)

Brain-computer interface based on steady-state visual evoked potential has been widely studied due to the high information transfer rate, little user training, and wide subject applicability. However, there are also disadvantages such as visual discomfort and “BCI illiteracy.” To address these problems, this study proposes to use low-frequency stimulations, which can simultaneously elicit visual evoked potential and pupillary response to construct a hybrid BCI system. Classification accuracy was calculated using supervised and unsupervised methods, respectively, and the hybrid accuracy was (...) obtained using a decision fusion method to combine the information of VEP and PR. Online experimental results from 10 subjects showed that the averaged accuracy was 94.90 ± 2.34% for the supervised method and 91.88 ± 3.68% for the unsupervised method, which correspond to the ITR of 64.35 ± 3.07 bits/min and 33.19 ± 2.38 bpm, respectively. Notably, the hybrid method achieved higher accuracy and ITR than that of VEP and PR for most subjects, especially for the short data length. Together with the subjects’ feedback on user experience, these results indicate that the proposed h-BCI with the low-frequency stimulation paradigm is more comfortable and favorable than the traditional SSVEP-BCI paradigm using the alpha frequency range.

The paper investigates relationship between working memory efficiency, defined as the result of its’ processing & storage capacity and the tendency to create assosiative memory distortions ; yield under the influence of external, suggesting factors. Both issues were examined using extended version of Deese-Roediger-McDermott procedure, modified in order to meet the study demands. Suggestion was contained in an ostentatious feedback information the participants received during the DRM procedure. Working memory was measured by standardized tasks. Study included 3 conditions, (...) differing in the quality of suggestion. Participants were assigned into 3 groups, depending on results they achieved completing the WM tasks. Obtained results alongside the previously set hypothesis, revealed that WM impacts individuals’ tendency to create false memories in DRM and that the individuals showing higher rates in WM tasks are less willing to yield to suggestion compared to those with lesser ones. It also showed that the greater amount to shift, emerges under the negative suggestion condition. Notwithstanding that the interaction effect did not achieve saliency, both analyzed factors are considered as meaningful to explain memory suggestion susceptibility in presented study. Although, obtained results emphasize the crucial role of WM efficiency, that is believed to decide the magnitude of feedback that is influential in every subject. Therefore, issue demands further exploration. (shrink)

Relational database management system is the most popular database system. It is important to maintain data security from information leakage and data corruption. RDBMS can be attacked by an outsider or an insider. It is difficult to detect an insider attack because its patterns are constantly changing and evolving. In this paper, we propose an adaptive database intrusion detection system that can be resistant to potential insider misuse using evolutionary reinforcement learning, which combines reinforcement learning and evolutionary learning. The (...) model consists of two neural networks, an evaluation network and an action network. The action network detects the intrusion, and the evaluation network provides feedback to the detection of the action network. Evolutionary learning is effective for dynamic patterns and atypical patterns, and reinforcement learning enables online learning. Experimental results show that the performance for detecting abnormal queries improves as the proposed model learns the intrusion adaptively using Transaction Processing performance Council-E scenario-based virtual query data. The proposed method achieves the highest performance at 94.86%, and we demonstrate the usefulness of the proposed method by performing 5-fold cross-validation. (shrink)

The area of smart power grids needs to constantly improve its efficiency and resilience, to provide high quality electrical power in a resilient grid, while managing faults and avoiding failures. Achieving this requires high component reliability, adequate maintenance, and a studied failure occurrence. Correct system operation involves those activities and novel methodologies to detect, classify, and isolate faults and failures and model and simulate processes with predictive algorithms and analytics. In this paper, we showcase the application of a complex-adaptive, self-organizing (...) modeling method, and Probabilistic Boolean Networks, as a way towards the understanding of the dynamics of smart grid devices, and to model and characterize their behavior. This work demonstrates that PBNs are equivalent to the standard Reinforcement Learning Cycle, in which the agent/model has an interaction with its environment and receives feedback from it in the form of a reward signal. Different reward structures were created to characterize preferred behavior. This information can be used to guide the PBN to avoid fault conditions and failures. (shrink)

This study examined the efficacy of corrected feedback for improving consent recall throughout the course of an ongoing longitudinal study. Participants were randomly assigned to either a corrected feedback or a no-feedback control condition.

The corrected feedback group received corrections to erroneous responses and the no-feedback control group did not. The feedback group displayed significantly (...) greater recall overall and in specific content areas. Results support the use of corrected feedback for improving consent recall. (shrink)

Most clinical neurofeedback studies based on functional magnetic resonance imaging use the patient's own neural activity as feedback. The objective of this study was to create a subject-independent brain state classifier as part of a real-time fMRI neurofeedback system that can guide patients with depression in achieving a healthy brain state, and then to examine subsequent clinical changes. In a first step, a brain classifier based on a support vector machine was trained from the neural information of happy (...) autobiographical imagery and motor imagery blocks received from a healthy female participant during an MRI session. In the second step, 7 right-handed female patients with mild or moderate depressive symptoms were trained to match their own neural activity with the neural activity corresponding to the “happiness emotional brain state” of the healthy participant. The training was carried out using the rt-fMRI NF system guided by the brain-state classifier we had created. Thus, the informative voxels previously obtained in the first step, using SVM classification and Effect Mapping, were used to classify the Blood-Oxygen-Level Dependent activity of the patients and converted into real-time visual feedback during the neurofeedback training runs. Improvements in the classifier accuracy toward the end of the training were observed in all the patients [Session 4–1 Median = 6.563%; Range = 4.10–27.34; Wilcoxon Test, 2-tailed p = 0.031]. Clinical improvement also was observed in a blind standardized clinical evaluation [HDRS CE2-1 Median = 7; Range 2 to 15; Wilcoxon Test, 2-tailed p = 0.016], and in self-report assessments [BDI-II CE2-1 Median = 8; Range 1–15; Wilcoxon Test, 2-tailed p = 0.031]. In addition, the clinical improvement was still present 10 days after the intervention [BDI-II CE3-2_Median = 0; Range −1 to 2; Wilcoxon Test, 2-tailed p = 0.50/ HDRS CE3-2 Median = 0; Range −1 to 2; Wilcoxon Test, 2-tailed p = 0.625]. Although the number of participants needs to be increased and a control group included to confirm these findings, the results suggest a novel option for neural modulation and clinical alleviation in depression using noninvasive stimulation technologies.

The importance of including performance-related body mechanics into music education to improve performance quality and prevent performance-related injuries has been stressed by many researchers recently. However, it is unclear how this information could be delivered most effectively. The somatic method ‘Timani’ provides a practical solution by combining expertise in music performance and functional body mechanics with the goal of achieving a more efficient playing technique. Since no in-depth study has been conducted to assess the method before, we explored the (...) impact of this method on young musicians’ performance through an online, 4-week-long Timani intervention with a mixed-methodology design. 17 students were recruited from the Norwegian Academy of Music. They participated in two group workshops at the beginning and the end of the project and received four individual Timani sessions administered by certified teachers. We collected survey data at the workshops about performance-related pain and self-efficacy, and qualitative feedback after each session. In addition, all sessions were observed by the researcher and semi-structured interviews were conducted with the teachers about the perceived outcomes and their experiences with teaching the method online. Our findings show that the intervention had a positive impact on a physical, professional, and to some extent, psychological and behavioral level. The improvements included better posture when playing, enhanced control and dexterity in the upper extremities, and improved breathing mechanisms. The seven students who had performance-related pain pre-intervention reported a reduction in the discomfort. The positive results were achieved by the dual expertise of the teachers in music performance and functional body mechanics, the structure of the sessions, the communication, and the pedagogical tools used. Both students and teachers felt that administering the sessions online was satisfactory and produced good results. Timani is a promising method to establish healthy playing and singing habits thus improving performance quality and preventing performance-related problems and has great potential in reducing pre-existing injuries and pain. Also, it can be effectively taught online which has further implications for the logistics of delivery. (shrink)

The feedback concealed information test (fCIT) is a new variant of the CIT that added feedback about participants’ concealing performances in the classical CIT. The advantage of the fCIT is that the resulting feedback related event-related potentials (ERPs) can be used to detect concealed information. However, the detection efficiency of feedback-based ERPs varies across studies. The present experiment examined whether the extent participants believed the feedback influenced their detection efficiency. Specifically, participants did a (...) mock crime and were then tested in a fCIT. Following the fCIT, participants were asked to report how much they believed the feedback was accurate. Results showed that there were no significant correlations between the amplitude of the feedback related negativity (FRN), feedback P300, and participants’ self-report at the group level. However, individual analyses showed that the detection efficiency of both the FRN and feedback P300 were influenced by participants’ belief about the presented feedback. The detection efficiency of the FRN and the feedback P300 was higher among participants who believed the feedback. These findings suggest that the fCIT is dependent to some extent on the participants’ level of belief in the feedback. (shrink)

The process of integration of digital technologies into the structure of social production and distribution leads to a series of definite trends in capitalist development. These trends are regular and interdependent. The acceleration of information exchange provides an opportunity to replace the Fordism with a thriftier network model, which involves outsourcing and reducing the longevity of contractual obligations and hiring relationships, which leads to the precarization of labor of a certain social group, which can be described as “precariat”. The (...) change in working conditions leads to the change in ways of increasing labor productivity, which is the reason for the emergence of “societies of control” characterized by: distributed power, embedding previously external coercion into the personality, affective engineering, prolongation of the educational process, increasing tempo and rhythm of work, spreading the project as the form of work replacing routine forms, and the emergence of a liquid short-term identity inherent in representatives of the precariat. This article aims to discover and demonstrate the interconnection between these processes. Achieving this goal will open the way to a more thorough separate study of each of these processes in the future but this research will be made from the perspective of their systemic unity. According to the purpose of the article, the structure of work is the following: the first section is devoted to the acceleration of social time, which is connected with the compression of social space and with the change in scale in which commercial and state enterprises can operate. Quick positive feedback, which is provided by the digital network, leads to changes in the infrastructure of enterprises and the transformation of production and logistics models. In addition, the acceleration of the feedback between the employee and the employer leads to the precarization of labor, which is accompanied by the appearance of “societies of control”. (shrink)
