Professional skill development was never as critical as it has become with the changing nature of globalized work place. With the change in pace of business, the customer expectations from organizations has increased in terms of squeezed time-to-market, faster response to customer needs and demands for better services. Organizations are increasingly becoming focused on how workplace professional skill development of employees can be structured or orchestrated to shorten time-to-professional expertise of their employees. It is becoming increasingly challenging (...) for organizations to develop their employees at faster rate so that they can perform their job even more efficiently and effectively. The longer time-to-proficiency of employees may impact time-to-market of organizations and may also result in losing business to competition. This paper presents the review of previous research studies on current modes and modalities of professional skill development in organizations and present initial findings on training and development approaches taken by organizations to accelerate time-to-professional expertise of their employees. This paper is aimed at making a wider call-for-research in the area of organizations’ focus on shortening the time to develop professional skills of their employees. (shrink)

The ability to imagine objects undergoing rotation (mental rotation) improves markedly with practice, but an explanation of this plasticity remains controversial. Some researchers propose that practice speeds up the rate of a general-purpose rotation algorithm. Others maintain that performance improvements arise through the adoption of a new cognitive strategy—repeated exposure leads to rapid retrieval from memory of the required response to familiar mental rotation stimuli. In two experiments we provide support for an integrated explanation of practice effects in mental rotation (...) by combining behavioral and EEG measures in a way that provides more rigorous inference than is available from either measure alone. Before practice, participants displayed two well-established signatures of mental rotation: Both response time and EEG negativity increased linearly with rotation angle. After extensive practice with a small set of stimuli, both signatures of mental rotation had all but disappeared. In contrast, after the same amount of practice with a much larger set both signatures remained, even though performance improved markedly. Taken together, these results constitute a reversed association, which cannot arise from variation in a single cause, and so they provide compelling evidence for the existence of two routes to expertise in mental rotation. We also found novel evidence that practice with the large but not the small stimulus set increased the magnitude of an early visual evoked potential, suggesting increased rotation speed is enabled by improved efficiency in extracting three-dimensional information from two-dimensional stimuli.

This book deals with solving a pressing organizational challenge of bringing employees up to speed faster. In the fast-paced business world, organizations need faster readiness of employees to handle the complex responsibilities of their jobs. The author conducted an extensive doctoral research study with 85 global experts across 66 project cases to explore the practices and strategies that were proven to reduce time to proficiency of employees in a range of organizations worldwide. This book provides the readers with a (...) first-hand account of findings exclusively related to training and learning strategies, instructional methods, and curriculum design. This book delivers over 21 training and learning strategies across online learning, classroom instructions, and on-the-job learning. These strategies will allow training designers and learning specialists to design workplace training programs that hold the potential to shorten time to proficiency of employees. The book not only describes findings of the study and theoretical underpinnings, but it also provides practical guidance for implementation to equip corporate learning specialists, HR professionals, training leaders, performance consultants, and direct managers.

Tetris provides a difficult, dynamic task environment within which some people are novices and others, after years of work and practice, become extreme experts. Here we study two core skills; namely, choosing the goal or objective function that will maximize performance and a feature-based analysis of the current game board to determine where to place the currently falling zoid so as to maximize the goal. In Study 1, we build cross-entropy reinforcement learning models to determine whether different goals result in (...) different feature weights. Two of these optimization strategies quickly rise to performance plateaus, whereas two others continue toward higher but more jagged heights. In Study 2, we compare the zoid placement decisions made by our best CERL models with those made by 67 human players. Across 370,131 human game episodes, two CERL models picked the same zoid placements as our lowest scoring human for 43% of the placements and as our three best scoring experts for 65% of the placements. Our findings suggest that people focus on maximizing points, not number of lines cleared or number of levels reached. They also show that goal choice influences the choice of zoid placements for CERLs and suggest that the same is true of humans. Tetris has a repetitive task structure that makes Tetris more tractable and more like a traditional experimental psychology paradigm than many more complex games or tasks. Hence, although complex, Tetris is not overwhelmingly complex and presents a right-sized challenge to cognitive theories, especially those of integrated cognitive systems. (shrink)

A consistent claim from governments around the world during the Coronavirus pandemic has been that they were following the science. This raises the question, central to this paper, of what and whose knowledge is or should be sought, which is being side-lined through the choice of particular framings and discourses, and with what consequences for the creation and implementation of evidence-based policy to tackle wicked problems. Through the lens of Fricker’s epistemic injustice, I problematise the expertise that has guided (...) the COVID-19 response as epistemically narrow and argue that counteracting a monolithic culture of expertise requires tackling the structural inequalities in the systems of knowledge production to diversify the social and epistemological foundations of science. Drawing on Post-normal Science (PNS) theory, I suggest that the expertise needed to respond to the challenges of a post-COVID world is one that embraces greater pluralism, avoids groupthink, challenges the accepted orthodoxy and helps us revert old models and rigid path dependencies that so often neglect the lived realities and demands of those left behind. This can only be realised by overcoming epistemic injustice and embracing epistemic democracy in the practice of evidence-based policy. (shrink)

“Ethics” is used as a label for a new kind of expertise in the field of science and technology. At the same time, it is not clear what ethical expertise consists in and what its political status in modern democracies can be. Starting from the “participatory turn” in recent social research and policy, we will argue that bioethical reasoning has to include public views of and attitudes towards biomedicine. We will sketch the outlines of a bioethical conception (...) of “public understanding of ethics,” addressing three different issues: (a) the methodological relevance of moral questions and problems raised by lay persons in everyday life regarding biomedicine and technology, (b) the normative relevance of such lay moralities for the justification of ethical decisions, and (c) the necessity of public deliberation in this context. Finally, we draw conclusions in view of the concepts and methods such a conception of “public understanding of ethics” should employ. (shrink)

Regulating technologies, innovations and risks is an activity that, as much as scientific research needs proofs and evidence. It is the site of development of a distinct kind of science, regulatory science. This special issue addresses the question of the standards of knowledge governing how we test, assess and monitor technologies and their effects. This topic is relevant and timely in the light of problematics of regulation of innovation, regulatory failure and capture. Given the enormous decisions and stakes regulatory science (...) commends, it becomes crucial to ask where its standards come from and gain credibility, but also what valuations of technology and appreciations of their risks or benefits do they embed, and who controls them? This paper introduces the four contributions comprising the special issue, and outlines a perspective from which to question the construction of regulatory science or, in the terminology adopted here, the authorization and standardization of regulatory knowledge, particularly the role of networks of scientific experts therein.

Acquiring expertise in a task is often thought of as an automatic process that follows inevitably with practice according to the log‐log law (aka: power law) of learning. However, as Ericsson, Chase, and Faloon (1980) showed, this is not true for digit‐span experts and, as we show, it is certainly not true for Tetris players at any level of expertise. Although some people may simply “twitch” faster than others, the limit to Tetris expertise is not raw keypress (...) time but the techniques acquired by players that allow them to use the tools provided by the hardware and software to compensate for the game's relentlessly increasing drop speed. Unfortunately, these increases in drop speed between Tetris levels make performance plateaus very short and quickly followed by game death. Hence, a player's success at discovering, exploring, and practicing new techniques for the tasks of board preparation, board maintenance, optimal placement discovery, zoid rotation, lateral movement of zoids, and other tasks important to expertise in Tetris is limited. In this paper, we analyze data collected from 492 Tetris players to reveal the challenges they confronted while constructing expertise via the discovery of new techniques for gameplay at increasingly difficult levels of Tetris.

What does it mean to be an expert? What sort of authority do experts really have? And what role should they play in today's society? Addressing why ever larger segments of society are skeptical of what experts say, Expertise: A Philosophical Introduction reviews contemporary philosophical debates and introduces what an account of expertise needs to accomplish in order to be believed. Drawing on research from philosophers and sociologists, chapters explore widely held accounts of expertise and uncover their (...) limitations, outlining a set of conceptual criteria a successful account of expertise should meet. By providing suggestions for how a philosophy of expertise can inform practical disciplines such as politics, religion, and applied ethics, this timely introduction to a topic of pressing importance reveals what philosophical thinking about expertise can contribute to growing concerns about experts in the 21st century.

Although taste and smell seem hard to imagine, some people nevertheless report vivid imagery in these sensory modalities. We investigate whether experts are better able to imagine smells and tastes because they have learned the ability, or whether they are better imaginers in the first place, and so become experts. To test this, we first compared a group of wine experts to yoked novices using a battery of questionnaires. We show for the first time that experts report greater vividness (...) of wine imagery, with no difference in vividness across sensory modalities. In contrast, novices had more vivid color imagery than taste or odor imagery for wines. Experts and novices did not differ on other vividness of imagery measures, suggesting a domain‐specific effect of expertise. Critically, in a second study, we followed a group of students commencing a wine course and a group of matched control participants. Students and controls did not differ before the course, but after the wine course students reported more vivid wine imagery. We provide evidence that expertise improves imagery, exemplifying the extent of plasticity of cognition underlying the chemical senses. (shrink)

Expertise is a cognitive achievement that clearly involves experience and learning, and often requires explicit, time-consuming training specific to the relevant domain. It is also intuitive that this kind of achievement is, in a rich sense, genuinely perceptual. Many experts—be they radiologists, bird watchers, or fingerprint examiners—are better perceivers in the domain(s) of their expertise. The goal of this paper is to motivate three related claims, by substantial appeal to recent empirical research on perceptual expertise: Perceptual (...) expertise is genuinely perceptual and genuinely cognitive, and this phenomenon reveals how we can become epistemically better perceivers. These claims are defended against sceptical opponents that deny significant top-down or cognitive effects on perception, and opponents who maintain that any such effects on perception are epistemically pernicious.

Perceptual malleability and diversity can stem from perceptual learning, expertise, genetics, disease, or accident. Perceptual malleability and diversity force us to reject the claim that perceptual capacities, perceptual experience, and perceptual content are universal across subjects and times. And it casts doubt on the presumption of a universal human perceptual nature. However, it does not directly challenge perceptual objectivity, understood as the claim that one can perceive a world of things and features that are independent from oneself and one's (...) experiences and that could be perceived by other subjects.

In recent years a new discussion on the nature of philosophical expertise has emerged: whether philosophers possess a special kind of expertise, what such expertise would entail, how to measure it, and related concerns. The aim of the present article is to clarify certain related points across these debates in the hope of paving a clearer path forward, by addressing the following. (1) The expertise defense, which seems central to many discussions on methodology and expertise, (...) has been misconstrued at times. (2) Questions of expertise and methodology could be separated more clearly. (3) The study of expertise may be important in its own right; however, there may be good reasons to give priority to methodological concerns. (4) Finally, when viewed in light of methodological concerns, a new project emerges when engaging with recent contributions to the expertise debate. The present article attempts a brief outline of this project. (shrink)

One of the most influential studies in all expertise research is de Groot’s (1946) study of chess players, which suggested that pattern recognition, rather than search, was the key determinant of expertise. Many changes have occurred in the chess world since de Groot’s study, leading some authors to argue that the cognitive mechanisms underlying expertise have also changed. We decided to replicate de Groot’s study to empirically test these claims and to examine whether the trends in the (...) data have changed over time. Six Grandmasters, five International Masters, six Experts, and five Class A players completed the think-aloud procedure for two chess positions. Findings indicate that Grandmasters and International Masters search more quickly than Experts and Class A players, and that both groups today search substantially faster than players in previous studies. The findings, however, support de Groot’s overall conclusions and are consistent with predictions made by pattern recognition models. (shrink)

Perceptual performance, anticipating opponents' strategies, and judging chess positions especially in subliminal processing is related to expertise level and dependent on chunking processes. It becomes obvious that chess expertise is a multidimensional phenomenon related predominantly to experience. Under consideration of chess expertise categorization, we conducted two priming experiments expanding existing designs by gradually increasing the target and task complexity. The main aim was the evaluation of potential visuocognitive limitations. The results reveal experts' perceptual superiority manifested by their (...) faster reaction times in settings with increased stimulus and task complexity. Further, experts' priming effects seem to be affected by the target content and/ or priming duration. For short prime duration, experts show priming effects only for less complex prime-target content. Interestingly, for longer prime duration and more complex prime-target content, all participants reveal priming effects. In summary, we argue that experts' visuocognitive processing is rooted in a more efficient visuocognition due to stored chunks of checking and mating constellations. We suggest that visuocognitive limitations are related also to the prime-target complexity as well as to the task. Further investigations must be conducted in order to elucidate the factors with an increased impact on chess players' performance. (shrink)

There is a deep distrust of experts in America today. Influenced by populist politics, many question or downright ignore the recommendations of scientists, scholars, and others with specialized training. It appears that expertise, a critical component of democratic life, no longer appeals to wide swaths of the body politic. On Expertise is a robust defense of the expert class. Ashley Rose Mehlenbacher examines modern and ancient theories of expertise through the lens of rhetoric and interviews some forty (...) professionals, revealing how they understand their own expertise and how they came to be known as “experts.” She shows that expertise requires not only knowledge and skill but also, crucially, an acknowledgment by others—both specialists and laypeople—that one is a credible authority. At its heart, expertise is a rhetorical construct, and to be persuasive, experts must have the ability to apply their knowledge and skills rightly—in the right way, at the right time, to achieve the right end. Ultimately, Mehlenbacher argues that experts apply their technical knowledge effectively and win others’ trust through acting prudently and cultivating goodwill. Timely, practical, and sophisticated, On Expertise provides vital scaffolding for our understanding of expertise and its real-world application. This book is essential for beginning the work of rehabilitating the expert class amid a politics of extreme populism and anti-intellectualism. (shrink)

One of the dominant behavioral markers of visual-expert search strategy, Holistic Visual Processing (HVP), suggests that experts process information from a larger region of space in conjunction with a more focused gaze pattern in order to improve search speed and accuracy. To date, extant literature suggests that visual search expertise is domain specific, including HVP and its associated behaviors. The current study is the first to use eye tracking to directly measure the HVP strategies of two expert groups, radiologists (...) and architects, in comparison to one another and a novice control. In doing so, we replicated and extended this prior research: visual expertise is domain specific. However, our eye tracking data indicate that contrary to this prior work, HVP strategies are transferable across domains. Yet, despite the transfer of HVP strategies, there is neither reduced search time nor greater accuracy in visual search outside of an expert’s domain. Therefore, our data suggest that HVP behaviors are a particular form of visual search mechanism that, outside of an expert’s native search-ecology, are not necessarily conducive to more general visual search success. It is in addition to explicit knowledge of an expert’s domain, how to search, and where to search, that HVP strategies are their most effective for visual search success. (shrink)

Psychologists and philosophers tend to treat expertise as a property of special individuals. These are individuals who have devoted much more time than the general population to the acquisition of their specific expertises. They are often said to pass through stages as they move toward becoming experts, for example, passing from an early stage, in which they follow self-conscious rules, to an expert stage in which skills are executed unconsciously. This approach is ‘one-dimensional’. Here, two extra dimensions are (...) added. They are drawn from the programme known as Studies of Expertise and Experience (SEE) and its ‘Periodic Table of Expertises’. SEE, which is sociological, and/or Wittgensteinian, in inspiration, takes expertise to be the property of groups; there are ‘domains’ of expertise. Under SEE, level of expertise grows with embedding in the society of domain experts; the key is the transmission of domain-specific tacit knowledge. Thus, one extra dimension is degree of exposure to tacit knowledge. Under SEE, domains can be big or small so there can be ‘ubiquitous tacit knowledge’, such as natural-language-speaking or other elements of general social behaviour, which belong to every member of a society. The second extra dimension is, therefore, ‘esotericity’. The resulting three-dimensional ‘expertise-space’ can be explored in a number of ways which reveal the narrowness of the analysis and the mistakes that have been made under the one-dimensional model.

L’Inra a mis en place en 2002 une activité d’expertise scientifique collective dans ses domaines de compétences – agriculture, environnement, alimentation – pour répondre à des questions d’action publique, portées principalement par les ministères de l’agriculture et de l’écologie. C’est sur la base de l’expérience acquise qu’ont été formulés les principes qui encadrent l’exercice et qui figurent dans la charte de l’expertise scientifique à l’Inra, et qu’on été construites les procédures de conduite qui en garantissent la qualité. Cet (...) article s’attache à la phase initiale du processus, déterminante pour la pertinence du travail, consacrée à l’instruction de la question d’expertise et à sa traduction de la sphère de l’action à celle de la recherche. Pour les experts, il s’agit de saisir le contexte, les enjeux, la logique de la commande, et pour les décideurs, de comprendre ce qu’ils peuvent attendre de la démarche d’analyse et d’assemblage des connaissances dans les limites de temps assignées à l’exercice.In 2002, Inra included collective expert scientific studies in its areas of competence – agriculture, environment and food – in response to public policy issues mainly arising in the Ministries of Agriculture and Ecology.

This article describes on the first phase of the process, which is decisive in terms of the relevance of the work undertaken. For the experts, the task requires an understanding of the context, the issues and the reasons for the request, while the decision-makers have to understand what they can expect from an approach that sets out to analyse and compile knowledge within the time allotted to the exercise.

In this paper we describe expertise as a way of seeing. We use match analysis `punditry’ as a setting to show how professional vision is interactionally achieved in TV sport broadcasts through environmentally coupled gestures enhanced by camera actions and a new technology of vision called telestrator. The paper is based on data from video sequences of football TV broadcasts where the pundit shows to the TV host in the studio and to the non-expert audience at home what happened (...) during a football match. We argue that the transparency of seeing is the product of an artfully instructed process whereby the pundit shows what should be seen, how it should be made accountable, and what the audience should expect in order to fully appreciate what they see. The paper shows how broadcasted match analysis expertise interactionally achieves this through the time-critical linking of talk, gesture, and technological environment. (shrink)

We provide the first demonstration of an artificial neural network encoding the perceptual templates that form an important component of the high level strategic understanding developed by experts. Experts have a highly refined sense of knowing where to look, what information is important and what information to ignore. The conclusions these experts reach are of a higher quality and typically made in a shorter amount of time than those of non-experts. Understanding the manifestation of such abilities in terms of (...) both the psychology of expert performance and the underlying neural mechanisms constitutes one of the most challenging problems in the cognitive sciences. Using perceptual templates we show how the amount of contextual information can change significantly even within a given task, the relationship between local and non-local contexts and finally why there is very little correlation between measures of intelligence and level of expertise in many of the most complex tasks performed by humans.

In 1902, the Calabrian brigand Giuseppe Musolino was tried on several counts of murder and many crimes of lesser magnitude. While the tale of the brigand’s 1898 false conviction, imprisonment, escape and then revenge sparked a national debate about the political and cultural meaning of brigandage, the trial came to focus on Musolino’s emotional state at the time of his crimes. Was he a cold-blooded and calculating killer who manipulated southerners into believing he was a folk hero? Or was (...) he an angry, passionate and insane murderer victimized by his own feelings? Both jurists and scientists weighed in to determine his culpability. By turning a political question of banditry or brigandage into a psychological question of morbid or criminal emotions, the trial politicized the criminal character. This article examines the perspectives on emotions that shaped Musolino’s trial, and how psychiatric knowledge came to challenge legal notions of insanity and culpability. It argues that the determination of emotions as motives served to de-legitimize the rationale and political motives of the defendant, in turn politicizing his emotions and character. At the same time, the cause of Musolino’s crime and his culpability represented the failures of national unification and the ongoing tensions between the North and South of Italy. The introduction of psychiatric expertise into the criminal court pushed judgement and punishment to examine increasingly who a person was as opposed to what that person had done. The court’s definition of who a person ‘was’, was a matter of how that person felt. (shrink)

How can we help people develop judgement and decision skills? One approach is to teach formal methods such as decision analyses, but these are difficult to apply in ill-structured settings, and the methods are unworkable when one is under time pressure and uncertain conditions. If we regard these skills as types of expertise that can be developed, then in a given domain we may attempt to define the cues, patterns, and strategies used by experts, and develop a programme (...) to teach people how to think like experts. However, in many settings this can be impractical. A different approach to decision skills training is to teach people how to learn like experts. By identifying a set of strategies used by experts to develop their proficiency at decision making, we can develop a programme aimed at helping people become reflective practitioners. This article describes such a training programme. (shrink)

The phrase ‘trading zone’ is often used to denote any kind of interdisciplinary partnership in which two or more perspectives are combined and a new, shared language develops. In this paper we distinguish between different types of trading zone by asking whether the collaboration is co-operative or coerced and whether the end-state is a heterogeneous or homogeneous culture. In so doing, we find that the voluntary development of a new language community—what we call an inter-language trading zone—represents only one of (...) four possible configurations. In developing this argument we show how different modes of collaboration result in different kinds of trading zone, how different kinds of trading zone may be ‘nested’ inside each other and discuss how a single collaboration might move between different kinds of trading zone over time. One implication of our analysis is that interactional expertise is a central component of at least one class of trading zone.Keywords: Trading zones; Interactional expertise; Interdisciplinarity; Creole.

What does it mean for an epidemic to end, and who gets to declare that it is over? This multidisciplinary spotlight issue provides 18 case studies, each examining specific epidemics and their ends as well as the methodologies used to measure, gauge, and define an epidemic's end. They demonstrate that an epidemic's end is often contentious, raising issues of competing authority. Various forms of expertise jostle over who declares an end, as well as what data and information should be (...) used to measure and define the end of an epidemic. As a result, it is more accurate to describe multiple endings to an epidemic: the medical end, the political end, and the social end. At the same time, multidisciplinary research into the ends of epidemics highlights the crucial role of information and measurement in an epidemic's end, as well as the ways in which ending forces observers to rethink and reconceptualize time. Whereas the declaration of an epidemic suggests a neatly defined period of emergency, the end is a messy process incorporating competing accounts of what went wrong and fears of the next epidemic, in which cycles of multiple diseases and overlapping social crises disrupt a simple return to normal life, articulating the nature of epidemics not just as medical phenomena, but also as fundamentally political and social ones. The end period therefore looks both forward and backward, often applying “lessons learned” from the history of the ended epidemic to the future, in anticipation of the next outbreak. Re-envisioning the future is a way to analyse and understand the past epidemic, and thereby to restore human agency into society's relationship with disease. (shrink)

Music can act as a mnemonic device that can elicit multiple memories. How musical and non-musical information integrate into complex cross-modal memory representations has however rarely been investigated. Here, we studied the ability of human subjects to associate visual objects with melodies. Musical laypersons and professional musicians performed an associative inference task that tested the ability to form and memorize paired associations between objects and melodies and to integrate these pairs into more complex representations where melodies are linked with two (...) objects across trials. We further investigated whether and how musical expertise modulates these two processes. We analyzed accuracy and reaction times of direct and indirect trials in both groups. We reasoned that the musical and cross-modal memory demands of musicianship might modulate performance in the task and might thus reveal mechanisms that underlie the association and integration of visual information with musical information. Although musicians showed a higher overall memory accuracy, non-musicians’ accuracy was well above chance level in both trial types, thus indicating a significant ability to associate and integrate musical with visual information even in musically untrained subjects. However, non-musicians showed shorter RTs in indirect compared to direct trials, whereas the reverse pattern was found in musicians. Moreover, accuracy of direct and indirect trials correlated significantly in musicians but not in non-musicians. Consistent with previous accounts of visual associative memory, we interpret these findings as suggestive of at least two complimentary mechanisms that contribute to visual-melodic memory integration. A default mechanism that mainly operates at encoding of complex visual-melodic associations and that works with surprising efficacy even in musically untrained subjects. A retrieval-based mechanism that critically depends on an expert ability to maintain and discriminate visual-melodic associations across extended memory delays. Future studies may investigate how these mechanisms contribute to the everyday experience of music-evoked memories. (shrink)

The extent to which game play is experienced as engaging is an important criterion for the playability of video games. This study investigates how video games can be designed towards increased levels of experienced engagement over time. For this purpose, two experiments were conducted in which a total of 35 participants repeatedly played a video game. Results indicate that experienced engagement is based on the extent to which the game provides rich experiences as well as by the extent to (...) which the game provides a sense of control. In view of the influence of both game features and players’ expertise on the levels of experienced richness and control, it is concluded that game features should be modified over time to maintain optimal levels of engagement.

Leonhard Thurneysser zum Thurn (1531–1596) was not only the personal physician of the elector of Brandenburg, but also a notorious alchemist, astrologist, pharmacist, and entrepreneur. As printer of his own works, he published a remarkable number of volumes on various subjects. Praised as a “miracle man” by some of his contemporaries, he was repeatedly accused of being a sorcerer, conjurer, and charlatan. This article focuses on his herbal book, printed in 1578. Taking into account the state of contemporary knowledge, this (...) paper examines Thurneysser’s explanations of plant names, his interpretation of plant signatures and his magical approach to pharmacology. Scientifically, Thurneysser’s innovations in these fields have not stood the test of time. However, examined within the context of intellectual history, they can be interpreted as strategies for laying claim to a field of expertise, by a man whose reputation was at risk. (shrink)

This article argues that the Statesman should be read as a historically informed reflection on the nature and possibility of political rule, and that it presents us with a dilemma precisely in this regard. On the one hand, as indicated by the famous myth on the evolution of the cosmos, politics is only possible today, in the age of Zeus, when man no longer is like a sheep, ruled by a caring herdsman, as he used to be in the age (...) of Cronus. Instead, he has become an expert who is capable of some degree of self-rule. On the other hand, however, as a ‘technocratic’ age, the present is marked by its loss of the ‘natural’ model for statesmanship. More specifically, when politics tends to be identified with technical expertise, it becomes difficult to make sense of the very idea of political rule. (shrink)

Following the eclectic itineraries of ‘Near East’ expert, R. M. Graves, this article tells a story of an ongoing Nakba (catastrophe) of small and large legal decisions. Without reducing the human catastrophe of the event of the Nakba (the 1948 Palestinian forced exodus), it engages with it as a legal event that crosses (in this story at least) from Cairo to Jerusalem, from the League of Nations’ era (1920–1946) to the United Nations’ era (1945–), from the governance of labour and (...) gender, to labour partition, and finally to the governance of municipalities through law and expertise. Graves’ relationship to both Cairo and Jerusalem was materialized through different forms of affective legal governance. Graves, who in his own dichotomous words was ‘neither a Zionist nor an anti-Semite’, managed Jerusalem across national lines in the wake of the UN Partition Plan (1947), and as the old empire was withdrawing right before Jerusalem itself became a site of the catastrophe—right before the Nakba.

Hugh MacColl (1837-1909), enseignant et tuteur, était l’un des contributeurs les plus prolifiques à cette section. Il soumettait ses contributions depuis Boulogne-sur-Mer, France. Son expertise portait essentiellement sur la probabilité géométrique, (...) les probabilités classiques et la logique. Après un bref aperçu de l’histoire de la section mathématique du Educational Times et de la correspondance de MacColl avec son directeur de publication, W. J. C. Miller, nous étudierons les contributions de MacColl à ce journal. (shrink)

Assess to quality diets is a basic human right. Geographical challenges and cultural traditions have contributed to the widespread malnutrition present among ethnic minorities of mountainous areas in Northwest Vietnam. Home gardens can play a role in increased diet diversity and micronutrient intakes. However, low production yields and plant diversity in ethnic home gardens have limited their contributions to household food security and nutrition. The pilot study tested a home garden intervention in weekly vegetable harvests and increasing household production and (...) consumption of diverse vegetables year-round. Food ethics issues encountered included limited access to quality food by resource-poor groups, conflicts arising from low preference and value given to some nutritious foods, limited access to information and technology for food production and consumption, each of which were addressed in the study design. The intervention includes: (1) nutrition-focused home garden training and (2) locally-adapted home garden packages consisting of garden planning, technical assistance, and high-yielding seed varieties. Twenty households from two ethnic villages in Son La province participated in the study and were randomly assigned into two groups (intervention and non-intervention). The total vegetable supply from weekly harvests of home garden produce was significantly higher in the intervention households (226 kg) compared to the non-intervention households (39 kg). The intervention group yielded 5.8 and 1.7 times more vegetables by weight and weight per area than those without the intervention. The vegetables were mainly consumed at home for both groups, but the intervention households gave more vegetables as gifts to neighbors. The intervention group cultivated a higher diversity of vegetables with a total of 42 different vegetables compared to 24 in the non-intervention group, which is reflected in an overall higher nutritional yield of vitamin A, iron, other micronutrients and phytochemicals. The home garden training significantly improved the amount, diversity and continuity of household food and nutrient supply. The home garden model is effective and could be scaled up to improve household vegetable supply and consumption, particularly in Northwest Vietnam. (shrink)

The unprecedented development of medical informatics is constantly transforming the concept of expertise in medical sciences in a way that has far-reaching consequences for both the theory of knowledge and the philosophy of informatics. Deep medicine is based on the assumption that medical diagnosis should take into account the wide array of possible health factors involved in the diagnostic process, such as not only genome analysis alone, but also the metabolome (analysis of all body metabolites important for e.g. drug-drug (...) interactions), microbiome (i.e. analysis of all bodily microorganisms interacting with host cells) or exposome (analysis of all environmental factors triggering potentially harmful cell mutations, such as UV radiation, heavy metals, various carcinogens, etc.). Deep data analysis is of tantamount importance for personalized diagnosis but, at the same time, hardly achievable by a regular human being. However, adequately designed artificial intelligence (e.g. a deep neural network) can undeniably be of great help for finding correlations between symptoms and underlying diseases. Nowadays AI applies to nearly every aspect of medicine, starting from the data analysis of scientific literature, through the diagnostic process, to the act of communication between physicians and their patients. Medical image processing algorithms greatly enhance the chances of successful recognition of melanoma or intestinal polyps. Communication tools designed for physicians use techniques known from social media to provide users with an opportunity to consult the case with colleagues from the same discipline. Natural language processing tools significantly improve doctor-patient communication by the automation of note-taking. Is this enough to support the claim that the non-epistemic competences in medicine are becoming more and more important? Can we attribute expertise only to a person? How is medical informatics changing the way most people usually understand human-computer interactions? (shrink)

Charles Perrow used the term normal accidents to characterize a type of catastrophic failure that resulted when complex, tightly coupled production systems encountered a certain kind of anomalous event. These were events in which systems failures interacted with one another in a way that could not be anticipated, and could not be easily understood and corrected. Systems of the production of expert knowledge are increasingly becoming tightly coupled. Unlike classical science, which operated with a long time horizon, many current (...) forms of expert knowledge are directed at immediate solutions to complex problems. These are prone to breakdowns like the kind discussed by Perrow. The example of the Homestake mine experiment shows that even in modern physics complex systems can produce knowledge failures that last for decades. The concept of knowledge risk is introduced, and used to characterize the risk of failure in such systems of knowledge production. (shrink)

Recently, epistocrats have challenged the value of democracy by claiming that policy outcomes can be improved if the electorate were narrowed to empower only those with sufficient knowledge to inform competent policy decisions. I argue that by centering on contesting how well regimes employ extant knowledge in decision-making, this conversation has neglected to consider how regimes influence the production of knowledge over time. Science and technology studies scholars have long recognized that political systems impact the productivity of expert research. (...) I argue that in order to evaluate which regime is “smarter,” we must consider not only how well they employ existing knowledge in decision-making, but we must also assess how those regimes influence the ongoing production of policy-relevant knowledge. Thus, I offer an instrumental defense of democracy based on its capacity to encourage a superior pattern and quality of expert research to inform policy decisions over time. Epistocracy may be effective at employing extant knowledge in the short run, but in the long run, democracy is a superior environment for producing knowledge to inform policy decisions. (shrink)

This article investigates whether religious experience can be conceived in such a way that the perceiver's religious expertise (via cognitive penetration or perceptual learning) contributes to the justificatory power of the experience. It also considers what kind of content religious experience would have to have to be able to justify standard types of religious beliefs. It argues that, against first impressions, religious expertise cannot supplement perceptual justification. At the same time, to the extent that religious experience has (...) singular contents or Gestalt contents, it may well be able to justify religious belief in virtue of such contents. (shrink)

Disciplinary boundaries become increasingly unclear when grappling with “wicked problems,” which present a complex set of policy, cultural, technological, and scientific dimensions. “T-shaped” professionals, i.e. individuals with a depth and breadth of expertise, are being called upon to play a critical role in complex problem-solving. This paper unpacks the notion of the “T-shaped expert” and seeks to situate it within the broader academic literature on expertise, integration, and developmental learning. A component of this project includes an exploratory study, (...) which is aimed at evaluating the emergent attributes of T-shaped expertise in two different educational programs completed between January and May in 2015. The two programs build disciplinary knowledge in science, technology engineering, and mathematics fields at the core, while expanding the students’ awareness and comprehension of other expertise. The courses introduced science and engineering students to case study topics focusing around complex human-technological-ecological systems in a nanotechnology and society course; and the governance of genetically modified organisms in a science, technology, and society course. We analyze pre- and post-test data from this pilot project before presenting findings that pertain to student learning, as well as variants in the methodology and reflect on the utility of the selected methodology for evaluating expertise as it evolves over time. The paper closes with a discussion of a theory of acquisition with implications for delineating early attributes and characteristics of T-shaped expertise. (shrink)

In Evangelium vitae, Pope St. John Paul II recognized that scientific progress would bring about new attacks on the dignity of the human person. Since that time, remarkable expansion in our knowledge and understanding of the human genome has brought forth questions of ownership rights via patents on human genes and related technology. This article argues that patenting human genes is incompatible with human dignity as it commodifies that which is priceless. In contrast, granting patents to manipulations of human (...) genes does not violate human dignity so long as it is utilized toward the common good.
