The object of the study is the continuous preservation of the multi-genre Cossack folk song, which represents a key purpose in the implementation of the preservation of the traditional mentality at the present stage. The subject of this work is the immanent complexes of traditional song culture in the folklore heritage. The purpose of this study is to structure the issue of the cultural interrelation of the ethnic canvas of the Kuban Cossack folk songs, in the originality of the genesis (...) of the vocal and performing specifics of modern creativity. When discovering the fundamental foundations of the vocal performance of the Cossack song, special attention is paid to the study of the folklore primary sources of the Kuban folklorists, V.G.Zakharchenko, A.D.Bigdai, G.M.Kontsevich. Along with this, an expert assessment of the characteristics of the Kuban Cossack folk song according to the genre classification component is an important feature of the performance of vocal samples today. The theoretical basis is in an analytical approach to the peculiarities of the performance of a local source from the point of view of substantiating the scientific nature of the subject under consideration according to the functionally oriented elements of the report: traditions, traditional manner of performance, interpretation of the text, song melody. Methodological basis: components of the study of the local singing tradition, modernization of folklore song documents, the method of consistency-the genre diversity of Cossack performance. The author's approach to the correlation of musical sources as methodological characteristics of the Kuban Cossack singing traditions has been developed. We test the proposed system when working with archival documents, in the diagnosis of song samples recorded from informants. The key aspect is the musicological analysis of the musical collections of Kuban Cossack folk songs from the point of view of the continuously developing, multifaceted changing performing skills of the soloist and choir. The author takes into account the introduced model of performing Cossack songs since the resettlement of the Black Sea Cossacks, who brought the baggage of multi-genre sources and eventually introduced the Kuban folk singing art. The scientific novelty of the research lies in the author's analytical systematization of authentic song compositions recorded by folklorists, in the analysis of multi-genre Kuban Cossack sources (selectively) for further active performance on stage. The specific directions of performance according to characteristic song genres are determined: historical, military, everyday, marching, lyrical, wedding, ceremonial, round dance, comic. The reproduced orientation of the nature of the continuous preservation of folklore sources in the revised performance interpretation of Cossack vocal works gives rise to significant broadcasting opportunities today.

We test the hypothesis that demographic continuity was a necessary condition of performable token post-communist social restorations. Demographic continuity means sufficient overlapping between populations of original and restored systems. Token social restoration refers to restorations where original and restored systems are identical. It is opposed to type restoration where original and restored systems are numerically different instances of the same type. The identity of original and restored systems in token restorations is achieved by performing various practices in the restored system (...) to establish institutional continuity with the original system. The restitution of property rights is the most important of them in the post-communist restorations. So our hypothesis claims that these practices cannot be performed without sufficient demographic continuity. We abstract the demographic continuity thresholds by measuring shares of survivors from the precommunist times in the population of Baltic countries by 1990. Our data confirm the hypothesis as in none of post-communist countries with demographic continuity below these thresholds there was property rights restitution. (shrink)

Abstract:Peirce's "Lesson in Elocution" (written ca. 1892) provides insight into his ideas on continuity and community through his knowledge of performance cultures such as theatre, elocution, rhetoric, and declamation. This unpublished manuscript constitutes the extant part of an application Peirce drafted to the Episcopal Church's General Theological Seminary for the position of elocution instructor. Continuing Henry C. Johnson, Jr.'s account (published in Transactions [2006] vol. 42, no. 4) of the Lesson as evidence of Peirce's religious practices, this article explores (...) the Lesson as demonstration of his performance knowledge and experience. What would Peirce have brought as philosopher and scientist to the teaching of elocution? Conversely, what did his performance knowledge bring to his work on continuity and community? Outlining significant differences between Peirce's semiotic approach and that of the Seminary's then-current instructor, Francis Thayer Russell, the article argues, employing selected performance theory concepts, that performance often operates in semiosis itself, as Peirce defined it.

A persistent belief in American culture is that males both outperform and have a higher inherent aptitude for mathematics than females. Using data from two school districts in two different states in the United States, this study used longitudinal multilevel modeling to examine whether overall performance on standardized as well as classroom tests reveals a gender difference in mathematics performance. The results suggest that both male and female students demonstrated the same growth trend in mathematics performance (as (...) measured by standardized test scores) over time, but females' mathematics grade-point average is significantly higher than males. These results are discussed in the context of present day standardized assessment in the United States that may motivate teachers to focus on higher expectations for mathematics performance regardless of gender, thus challenging cultural beliefs that stigmatize mathematics as masculine in the United States.

Shifts of attention within working memory based on retroactive (retro-) cues were shown to facilitate performance in working memory tasks. Although posterior asymmetries in the EEG, such as the contralateral delay activity (CDA), have been used to study the active storage of lateralized working memory representations, results on the relation of such asymmetric effects to retro-cue benefits remain inconclusive. We recorded EEG in a retro-cue working memory task with lateralized items and a continuous performance response. Following either a (...) selective or neutral retro-cue, participants adjusted the orientation of a central memory probe to the cued item. Selective retro-cues elicited an early posterior contralateral negativity (PCN), anterior directing attention negativity (ADAN) and a later modulation of CDA indicating that active storage was concentrated on the cued information. By dividing all trials into three within-condition performance quantiles, we could further show that high working memory accuracy was associated with a sustained increase of the CDA effect following the retro-cue. These results suggest that focusing resources on the active storage of relevant representations is an important factor regarding retro-cue benefits in working memory tasks. (shrink)

The relatively new practice of continuous sedation at the end of life (CS) is increasingly being debated in the clinical and ethical literature. This practice received much attention when a U.S. Supreme Court ruling noted that the availability of CS made legalization of physician-assisted suicide (PAS) unnecessary, as CS could alleviate even the most severe suffering. This view has been widely adopted. In this article, we perform an in-depth analysis of four versions of this ?argument of preferable alternative.? Our goal (...) is to determine the extent to which CS can be considered to be an alternative to PAS and to identify the grounds, if any, on which CS may be ethically preferable to PAS. (shrink)

Even though effects of High Performance Work Systems (HPWS) on employee performance have been widely investigated, there is no consensus on how this link is achieved. Drawing on Social Exchange Theory (SET), this paper attempts to shed more light in this relationship by investigating the mediating role of affective, normative, and continuance commitment in the relationship between HPWS and employee performance. Moreover, the potential moderating role of employee tenure on the HPWS—organizational commitment link is examined. Using data (...) from 342 subordinates and 115 supervisors from 111 service organizations in Greece, our multilevel analysis shows that affective commitment fully mediates the relationship between HPWS and employee performance. In addition, employee tenure positively moderates the relationships between HPWS and affective and normative commitment. The paper discusses theoretical implications and provides recommendations for practitioners. (shrink)

Gender discrimination continues to be a problem in organizations. It is therefore important that organizations use performance evaluation methods that ensure equal opportunities for men and women. This article reports the results of an experiment to investigate whether and, if so, how the gender of the rater and that of the ratee moderate the relationship between the level of subjectivity in performance appraisals and organizational attractiveness. Participants in the experiment were 313 undergraduate students. We predicted, and indeed established, (...) that as the probability increases that employee performance is evaluated by a female manager, women expect more positive outcomes of subjective, but not objective evaluation processes. Our data did not support our expectation that as the probability of being evaluated by a female manager increases, men expect less positive outcomes of subjective evaluation processes. The findings of this study contribute to our understanding of why women are over-represented in jobs with objective formula-based reward systems, such as piece-rate systems. They are also of interest to organizations that are looking for more ethical human resource management practices. (shrink)

Steve Sherlock’s The Performativity of Value: On the Citability of Cultural Commodities explores how social identity is increasingly constructed through the citation of cultural commodities—a process that has become “performative” of the U.S. cultural economy. Sherlock extends the work of Butler, Derrida, and the Bakhtin Circle to describe how the regeneration of exchange value involves the continual re-commodification of language.

The world is currently facing a wave of data centre construction. Fuelled by an explosion of data production and the emergence of edge computing, our cities are witnessing the materialisation of new architectural typologies that increasingly convolute notions of digital and bodily distinction. Whilst the last 2 decades have seen the proliferation of separate human and post-human urban environments, here we consider the agency and performativity of human communities within increasingly tangled contexts. As edge computing continues to bring the material (...) reality of data processing closer to our physical bodies, perhaps its time to reassess who, or what, our cities now serve. In an age of unprecedented digital transformation, when our identities seem to be ever more intangible, how we might perform within environments that are increasingly catering to our digital rather than bodily needs? Today, the Anthropocene expels nature to the periphery. Tomorrow, humans become marginalised—“weeds”, thriving in an epoch of data. (shrink)

Are works of music types of performance or are they continuants? Types are unchanging entities that could not have been otherwise; continuants can undergo change through time and could have been different. Picking up on this distinction, Guy Rohrbaugh has recently argued that musical works are continuants rather than performance-types. This paper replies to his arguments and, in the course of so doing, elaborates and defends the conception of musical works as types of performance. I end the (...) article by arguing that the conception of musical works as continuants is under-motivated and, ultimately, obscure. (shrink)

Philosophers of history in the past few decades have been predominantly interested in issues of explanation and narrative discourse. Consequently, they have focused consistently and almost exclusively on the historian’s output, thereby ignoring that historical scholarship is a practice of reading, thinking, discussing, and writing, in which successful performance requires active cultivation of certain skills, attitudes, and virtues. This paper, then, suggests a new agenda for philosophy of history. Inspired by a “performative turn” in the history and philosophy of (...) science, it focuses on the historian’s “doings” and proposes to analyze these performances in terms of epistemic virtue. It argues that historical scholarship is embedded in “practices” or “epistemic cultures,” in which knowledge is created and warranted by means of such virtues as honesty, carefulness, accuracy, and balance. These epistemic virtues, however, are not etched in stone: historians may highlight some of them, exchange one for another, or reinterpret their meaning. On the one hand, this suggests a rich area of research for historians of historiography. To what extent can consensus, conflict, continuity, and change in historical scholarship be explained in terms of epistemic virtue? On the other hand, the proposal outlined in this article raises a couple of philosophical questions. For example, on what grounds can historians choose among epistemic virtues? And what concept of the self comes with the notion of virtue? In addressing these questions, philosophy of history may expand its current scope so as to encompass not only “writings” but also “doings,” that is, the virtuous performances historians recognize as professional conduct.

This discussion paper addresses Ian Wilks’ defence of the risk‐related standard of competence that appears in Bioethics 11. Wilks there argues that the puzzle posed by Mark Wicclair in Bioethics 5 against Dan Brock's argument in favour of a risk‐related standard of competence — namely that Brock’s argument allows for situations of asymmetrical competence — is not a genuine problem for a risk‐related standard of competence. To show this, Wilks presents what he believes to be two examples of real situations (...) in which asymmetrical competence arises. I argue that insofar as Wilks equivocates two senses of competence in his examples — namely, competence to perform a task and competence in performing a task — Wilks is unable to illustrate the existence of real situations of asymmetrical competence. By examining the way in which Wilks equivocates two senses of competence in his examples, and by applying the results of this examination to the problem of patient competency within the medical field, I argue that not only does Wilks fail to show that situations of asymmetrical competence exist, but he is also unable to provide a foundation for understating how the risk‐related standard of competence can strike a balance between an individual’s autonomy and benevolent intervention. I thus conclude that insofar as Wilks fails to answer the objections raised by Wicclair and others against the risk‐related standard of competence, the risk‐related standard of competence continues to be undermined by the problem of asymmetrical competence.

Research on cognitive control has sparked increasing interest in recent years, as it is an important prerequisite for goal oriented human behavior. The paced auditory serial addition task has been used to test and train cognitive control functions. This adaptive, challenging task includes continuous performance feedback. Therefore, additional cognitive control capacities are required to process this information along with the already high task-load. The underlying neural mechanisms, however, are still unclear. To explore the neural signatures of the PASAT and (...) particularly the processing of distractive feedback information, feedback locked event-related potentials were derived from 24 healthy participants during an adaptive 2-back version of the PASAT. Larger neural activation after negative feedback was found for feedback related negativity, P300, and late positive potential. In early stages of feedback processing, a larger difference between positive and negative feedback responses was associated with poorer overall performance. This association was inverted in later stages. Together, our findings indicate stage-dependent associations between neural activation after negative information and cognitive functioning. Conceivably, increased early responses to negative feedback signify distraction, whereas higher activity at later stages reflects cognitive control processes to preserve ongoing performance.

The purpose of this work is to define performativity as a natural component of human cognition. The notion of performativity has many applications in various fields from performance studies to pragmatics, but in the recent years it has been introduced within cognitive science studies, where it is currently a subject of great debate. A working definition of performativity as a central component of the human mind that determines the relationship between the individual and the world is proposed. This definition (...) is intentionally general, because it works for every species, not only for humans. Performativity, in fact, is a capacity present in all cognitive systems that have a body because it allows the utilization of those cognitive abilities that evolutionary history has delivered to a species. The concept of performativity with a naturalistic and biologically based approach is analysed taking into account both evolutionary continuity and species-specific functions. In conclusion, an application of the natural performativity of language, a uniquely human function characterized by species-specific morphological structures that constitute constraints for language performativity, is proposed.

The study aims to identify the efficiency of the university education performance from the perspective of postgraduate and undergraduate students in international and Palestinian universities. The analytical descriptive approach was used for this purpose and the questionnaire was used as a main tool for data collection. The study community consists of: post graduate students, (23850) graduate students and (146355) undergraduate students. The sample of the study was 378 graduate students and 383 undergraduate students. The random stratified sample was used. (...) The Statistical Package of Social Sciences (SPSS) was also used for data analysis. The study reached a number of results, the most important of which are: The level of efficiency of educational performance in Palestinian and international universities from the point of view of postgraduate and undergraduate students was high. And that there are significant differences between the average views of the sample of the study on the efficiency of educational performance in Palestinian and international universities attributed to the University and to the benefit of international universities. The study concluded many recommendations, the most important of which is the necessity of continuing to develop e-learning strategies that affect the efficiency of educational performance and research commensurate with the university's position in the local and international community, which puts it on the best classification between local and international universities through e-learning.

Background: Observance of the patients’ bill of rights is one of the main features of moral codes in hospitals. In this regard, nurses bear great responsibility because they spend a long time with patients. Therefore, the continuous evaluation of the nurses’ performance and assessing their knowledge about the patients’ bill of rights are a need. Objectives: We aimed to determine the nurses’ awareness of the patients’ rights and measure their performance in this regard. Research design and participants: This (...) cross-sectional study was carried out in 2013. To measure the nurses’ knowledge and performance, 250 nurses and 300 patients were surveyed. The participants were selected randomly from five teaching hospitals in Tehran, Iran. Two questionnaires, one for nurses (17 questions) and the other for patients (11 questions), were applied. The data were analyzed in SPSS software using descriptive and inferential statistics. Ethical consideration: The research protocol was submitted and approved by the research and ethics committees of the participating hospitals. Additionally, the consent of all of the participants was obtained before the study. Findings: The mean score of the nurses’ knowledge regarding the patients’ rights was acceptable (69.85 ± 11.7 of 85). Furthermore, the mean score of nurses’ performance in observing the patients’ rights was relatively acceptable (11.2 ± 4.6 of 22). More experienced and educated nurses had higher knowledge regarding the patients’ rights, and patients with higher education level or experience of being hospitalized were less satisfied with the nurses’ performance. Conclusion: Nurses’ knowledge of the patients’ bill of rights was acceptable; however, observance of the patients’ rights was not. It seems that notification of the patients’ bill of rights has increased the nurses’ awareness of the patients’ rights, although improvement of the nurses’ performance needs more extensive measures.

Surveys in different countries (e.g. the UK, Belgium and The Netherlands) show a marked recent increase in the incidence of continuous deep sedation at the end of life (CDS). Several hypotheses can be formulated to explain the increasing performance of this practice. In this paper we focus on what we call the ‘natural death’ hypothesis, i.e. the hypothesis that acceptance of CDS has spread rapidly because death after CDS can be perceived as a ‘natural’ death by medical practitioners, patients' (...) relatives and patients.We attempt to show that the label ‘natural’ cannot be unproblematically applied to the nature of this end-of-life practice. We argue that the labeling of death following CDS as ‘natural’ death is related to a complex set of mechanisms which facilitate the use of this practice. However, our criticism does not preclude the view that CDS may be clinically and ethically justified in many cases. (shrink)

How to measure performance in charitable organisations continues to excite interest among academics and practitioners. Despite the intellectual interest, little consensus has emerged as to what are the best measures of performance in charities. This is against the backdrop of an increased demand by donors and other stakeholders on charities to provide information on their performance. Building on prior studies, this paper examines the measures of performance in charities using a hybrid methodological approach which consists of (...) 14 exploratory interviews and a quantitative survey of 105 chief executive officers/board of trustees of large British charities. The results of factor analysis and internal reliability produced five broad measures of performance of charities: financial measures; client satisfaction; management effectiveness; stakeholder involvement; and benchmarking, indicating that the overall performance of charities is best measured by a set of factors that reflect the multiple and diverse stakeholders associated with charities. Further analysis using structural equation modelling corroborates the results that non-financial measures such as management effectiveness, stakeholder involvement and benchmarking are important to the performance of charities.

Continuity is perhaps the most familiar characterization of the finitary character of the operations performed in computation. We sketch the historical and conceptual development of this notion by interpreting it as a unifying theme across three main varieties of semantical theories of programming: denotational, axiomatic and event-based. Our exploration spans the development of this notion from its origins in recursion theory to the forms it takes in the context of the more recent event-based analyses of sequential and concurrent computations, touching (...) upon the relations of continuity with non-determinism.

For scientific knowledge to be trustworthy, it needs to be dissociated from material interests. Disinterested research also performs other important non-instrumental roles. In particular, academic science has traditionally provided society with reliable, imaginative public knowledge and independent, self-critical expertise. But this type of science is not compatible with the practice of instrumental research, which is typically proprietary, prosaic, pragmatic and partisan. With ever-increasing dependence on commercial or state funding, all modes of knowledge production are merging into a new, ‘post-academic’ research (...) culture which is dominated by utilitarian goals. Growing concern about conflicts of interest is thus a symptom of deep-seated malaise in science and medicine. (shrink)

Performance Generating Systems (PGS) are rule- and task-based approaches to improvisation on stage in theatre, dance, and music. These systems require performers to draw on predefined source materials (texts, scores, memories) while working on complex tasks within limiting rules. An interdisciplinary research team at a large Western Canadian university hypothesized that learning to sustain this praxis over the duration of a performance places high demands on executive functions; demands that may improve the performers’ executive abilities. These performers need (...) to continuously shift attention while remaining responsive to embodied and environmental stimuli in the present, they are required to inhibit automated responses and impulses using the rules of the system, and they strive towards addressing multitasking challenges with fluidity and flexibility. This study set out to test the mentioned hypothesis deductively and identify mediating processes inductively, using mixed empirical methods. In a small sample experiment with a control group (28 participants; 15 in intervention group, 13 in control group), standardized quantitative tests of executive functions (D-KEFS) were administered before and after an eight-week intervention. Participant-reported qualitative observations from the praxis were also collected throughout the intervention for grounded analysis. Within the limitations of small sample data, we found both statistically significant and trending effects on inhibition, problem-solving initiation, fluidity, and cognitive flexibility. Examining the mediating process, we found that participants experienced significant challenges sustaining the practice halfway through the intervention. The participant-reported solutions to these challenges, which emerged as the strongest behavioural patterns when coding the qualitative data to saturation, were strategies of problem-solving and of re-directing attention. These strategies support and advance our understanding of the effects measured in the standardized tests. In terms of application, our results identify characteristics of PGS that could potentially maintain and strengthen executive functions over and above less demanding performing arts interventions. The results also deliver new insight into how PGS works, which may contribute to the development and teaching of this artistic practice. (shrink)

Early-Onset Schizophrenia (EOS) and Attention Deficit-Hyperactivity Disorder (ADHD) are early- onset neurodevelopmental disorders associated with cognitive deficits. The current study represents the first attempt to compare these groups on a comprehensive cognitive test battery in a longitudinal design over 25 years in order to enhance our knowledge of particular patterns resulting from the interaction between normal maturational processes and different illness processes of these disorders. In the baseline study, 19 adolescents with schizophrenia were compared to 20 adolescents with ADHD and (...) 30 healthy controls (HC), all between 12 and 18 years of age. After 13 years (T2) and after 25 years (T3) they were re-evaluated with the cognitive test battery. A cognitive Composite Score was used in a linear mixed model. The EOS group had a significant cognitive stagnation or deterioration from T1 to T2 compared to HC. However, the EOS group had the most positive change from T2 to T3, supporting a stable level of cognitive performance over the 25 year span. The ADHD group improved or had similar development as the HC group from T1 to T2. They continued to improve significantly compared to the HC group from T2 to T3. Individuals in the EOS group performed more impaired on the cognitive composite score compared to the HC group and the ADHD group at all three time points. Results might indicate a neurodevelopmental pathway of EOS with subnormal cognitive development specific in adolescence. In comparison, the ADHD group had a more consistent cognitive maturation supporting a maturational delay hypothesis of ADHD. (shrink)

The empirical basis for self-control in Dohsa-hou as it relates to effects on cognitive processes has been explored in a few studies of the Japanese psychotherapy, but not under standardized conditions with a strong predictive theory of control. This study reports on a series of experiments with the Dual Mechanisms of Control framework to clarify the possible regulatory mechanism of Dohsa-hou by focusing on shoulder movement, a key body movement task used by practitioners across applied settings. Cognitive control was operationalized (...) with the AX version of Continuous Performance Test paradigm for proactive control and a modified Stroop task paradigm for reactive control in a 3-arm parallel group trial study design. Healthy Japanese university students were assigned to a Dohsa-hou group that performed a shoulder movement task for few minutes, an active control group that performed a similar task, or a passive control group comprised of a resting condition. A total of 55 participants performed the AX-CPT and 57 participants performed the modified Stroop task before and after the group manipulation. In the AX-CPT, an increase in the error rate of AY trial from pre- to post-test was observed in the passive control group only, and found to be marginally higher in the passive control group relative to Dohsa-hou group at post-test. This indicated that Dohsa-hou moderated the activation of proactive control by repeated AX-CPT performance. The error rate of the Proactive Behavioral Index did not differ from zero at post-test only in the Dohsa-hou group, indicating flexible cognitive control. In the modified Stroop task, there was no difference between congruent and incongruent trials at post-test for the Dohsa-hou group only, indicating the facilitation of reactive control. The evidence for a balancing effect for the Dohsa-hou-based shoulder movement task indicates that clients experience a form of continuous self-monitoring, which might reduce mind-wandering from their focus on movement execution combined with iterative verbal feedback from the therapist. Overall, the results of the present study suggest that the self-regulatory mechanism promoted in clinical Dohsa-hou emphasizes guided shifts in attention to the reactive mode toward a balance of cognitive control.

Using a paradigm that allows a quasi-continuous tracking of memory performance over time, two experiments were designed to test the hypotheses that persons with a cognitively avoidant style of coping with threat manifest a dissociation between short-term and long-term retrieval of aversive information and persons with a vigilant coping style recall aversive information particularly well after long retention intervals, provided they are free to think about aversive events. Study 1 showed that avoiders manifest a poor memory for aversive pictures (...) after long retention intervals only. Study 2 replicated this finding. In addition, manipulation of the cognitive load during the retention interval influenced vigilants’ recall of aversive information in the predicted way. Results indicate that processes occurring during the retention interval are essential for individual difference in memory for aversive information and require similar attention as encoding, appraisal, and retrieval processes.

In this article we present symmetric diffusion networks, a family of networks that instantiate the principles of continuous, stochastic, adaptive and interactive propagation of information. Using methods of Markovion diffusion theory, we formalize the activation dynamics of these networks and then show that they can be trained to reproduce entire multivariate probability distributions on their outputs using the contrastive Hebbion learning rule (CHL). We show that CHL performs gradient descent on an error function that captures differences between desired and obtained (...) continuous multivariate probability distributions. This allows the learning algorithm to go beyond expected values of output units and to approximate complete probability distributions on continuous multivariate activation spaces. We argue that learning continuous distributions is an important task underlying a variety of real‐life situations that were beyond the scope of previous connectionist networks. Deterministic networks, like back propagation, cannot learn this task because they are limited to learning average values of independent output units. Previous stochastic connectionist networks could learn probability distributions but they were limited to discrete variables. Simulations show that symmetric diffusion networks can be trained with the CHL rule to approximate discrete and continuous probability distributions of various types. (shrink)

In this paper, I discuss the risks of brain injuries in collision and contact sports and make a proposal to address them without limiting the autonomy of athletes. I aim to analyse the circumstances of profound uncertainty that athletes are facing in terms of the long-term impact of brain injuries. My strategy is to circumvent drastic measures in dealing with such risks, such as banning certain sports or changing their nature by introducing constitutive rule changes, and to scaffold individual autonomy (...) instead. I will focus on two aspects. First, I address the choice whether to take up or continue to play a risky sport given the mentioned profound level of ignorance. I argue that we can scaffold autonomy to make rational choices, particularly by enabling the application of heuristics. Second, I discuss performative skills that can help to prevent brain injuries. It is important to consider collision and contact sports as instances of joint action. The performance of others is an important factor in determining the level of risk in such sports. Hence, supporting athlete’s skills to prevent collisions can reduce the risk of brain injury. I conjecture ways to scaffold players’ skills and performance with this aim in mind. (shrink)

The relationship between the continuity equation and the HamiltonianH of a quantum system is investigated from a nonstandard point of view. In contrast to the usual approaches, the expression of the current densityJ ψ is givenab initio by means of a transport-velocity operatorV T, whose existence follows from a “weak” formulation of the correspondence principle. Once given a Hilbert-space metricM, it is shown that the equation of motion and the continuity equation actually represent a system in theunknown operatorsH andV T, (...) due to the arbitrariness on the initial condition of the quantum state. The general solution is given in some cases of special interest and a straightforward application to relativistic quantum mechanics is performed. (shrink)

The aim of the research is to identify the relationship between the performance criteria and the achievement of the objectives of supervision which is represented in the performance of the job at the Islamic University in Gaza Strip. To achieve the objectives of the research, the researchers used the descriptive analytical approach to collect information. The questionnaire consisted of (22) paragraphs distributed to three categories of employees of the Islamic University (senior management, faculty members, their assistants and members (...) of the administrative board). A random sample of 314 employees was selected, 276 responses were retrieved with a return rate of 88.1%. The SPSS program was used to enter, process, and analyze the data. The results of the study showed a positive relationship between the performance criteria and the achievement of the control objectives represented by the job performance in the Islamic University from the point of view of the members (senior management, faculty and their assistants and the administrative board). The researchers also recommended a number of recommendations, including the provision of an appropriate level of control system components today through the continuous updating and development of performance standards and the need to provide the necessary physical and financial resources to continue the development and achievement within the university. Expand the development of technology in the various activities of the university through the construction of a complete and integrated system to support the control systems in the university to suit its size. The researchers also recommended the follow-up, review of the performance standards and work to modify them in line with the mission of the university and the goals that the university seeks to reach.

Stanisław Brzozowski was active as philosopher and literary critic for only a few years at the turn of the twentieth century, yet his writings are still inspire contemporary thinkers and critics. In every important phase of the development of Polish literary criticism, Polish intellectuals have acknowledged Brzozowski as a writer who had the courage and critical acumen to confront modernity and examine closely contemporary trends of thought from the perspective of social and individual life. This continued presence of the (...) celebrated critic cannot but be interesting for the researcher who is led to ask, what is so intriguing in Brzozowski’s work, why do successive generations of critics and intellectuals return to Brzozowski? Drawing on many important interpretations of Brzozowski’s work (Burek, Głowiński, Nycz), I want to show that in Brzozowski’s work it is possible to find everything contemporary criticism and thought needs, because his books contain, in nuce , projects and strategies which can be (and are) used in different ways by critics representing different ideologies and worldviews. Brzozowski worked out, or rather attempted to work out, ideas which are a source of modern critical projects but in addition his work comprises a repertoire of possibilities which contemporary critical thought can turn to its advantage. Brzozowski’s work can be also treated as a performative act, calling forth the reader’s response, in this way shedding new light on it. I also show that “performative consciousness” is both close to Brzozowski’s practice of writing and deeply rooted in his philosophical conviction. Brzozowski can be considered a representative of modernist, critical literature, in which reading and writing become a mode of experience, a privileged social discourse, and a “leaven,” an act and an activity.

This article continues from where the author's 2008 book The Meaning of Video Games concluded and concerns what he learned from playing the simulation game Spore by Sims-creator Will Wright, especially the extent to which a social-network model had become during the development process the infrastructural backbone of the game. Spore's approach to the problem of building an asynchronous content-creation and content-sharing system aligned the video game with the most important trends in text-based digital humanities scholarship today. Thus this article (...) compares video games and digital texts, not in terms of their supposedly shared narrative content (not in terms of their content at all) but, rather, formally—in terms of how they model complex systems, how both video games and digital-text environments work by creating networked environments for the production, reproduction, transmission, and reception (indeed for the continual reediting) of their respective content-objects. Both texts and video games are systems, with their own special affordances and constraints, that provide both “spores” and “spurs,” seeds and provocations, prompts for new performances of meaning.

Organizations continue to show renewed focus on managing their ethics programs by developing organizational infrastructures to support their ethics implementation efforts. An important part of this process has been the creation of an ethics officer position. Whether individuals appointed to the position are successful in the role or not may depend on a number of factors. This study presents a suggested framework for their effectiveness. The framework includes a focus on personal, organizational and situational factors to predict performance in (...) the role. The study examines the complex nature of the role. These include task complexity, low task visibility, role conflict, and role ambiguity. Personal, organizational and situational factors that can serve as buffers against the complexities associated with the role are presented. The study suggests that individuals with certain competencies and orientations may be better suitable for the ethics position, and firms need to consider key organizational and situational issues critical to the performance of an ethics officer. The research and practice implications of the study are given. (shrink)

In this paper, I discuss the risks of brain injuries in collision and contact sports and make a proposal to address them without limiting the autonomy of athletes. I aim to analyse the circumstances of profound uncertainty that athletes are facing in terms of the long-term impact of brain injuries. My strategy is to circumvent drastic measures in dealing with such risks, such as banning certain sports or changing their nature by introducing constitutive rule changes, and to scaffold individual autonomy (...) instead. I will focus on two aspects. First, I address the choice whether to take up or continue to play a risky sport given the mentioned profound level of ignorance. I argue that we can scaffold autonomy to make rational choices, particularly by enabling the application of heuristics. Second, I discuss performative skills that can help to prevent brain injuries. It is important to consider collision and contact sports as instances of joint action. The performance of others is an important factor in determining the level of risk in such sports. Hence, supporting athlete’s skills to prevent collisions can reduce the risk of brain injury. I conjecture ways to scaffold players’ skills and performance with this aim in mind. (shrink)

This article explores Lyotard’s notion of performativity through an engagement with McKenzie’s analysis of performance as a ‘formation of knowledge and power’ that has displaced the notion of discipline as the tool for social evaluation. Through conditions of ‘performance’ capitalism, education is to conform to a logic of performativity that ensures not only the efficient operation of the state in the world market, but also the continuation of a global culture of performance. I further trace Lyotard’s postmodern (...) aesthetic of experimentation through performance as an ‘event’ in an analogous attempt to track the process of cultural production in terms that acknowledge the temporality of the event so as not to reduce the artwork to a commodity, knowledge to information, and ‘performance’ to be managed. Where this has critical traction is in education, a site that deals with the intersection of politics, art, theory, philosophy and history—in short, a site where all aspects of ‘performance’ are fully realized. This article engages with the key ideas of these thinkers’ approaches to notions of performance, and assesses their relevance for an understanding of the ambiguities of ‘performance’ in contemporary education institutions.
