This paper explores the socio-epistemic practice of shopping for experts. I argue that expert shopping is particularly likely to occur on what Thi Nguyen calls cognitive islands. To support my argument, I focus on macroeconomics. First, I make a prima-facie case for thinking that macroeconomics is a cognitive island. Then, I argue that ordinary people are particularly likely to engage in expert shopping when it comes to macroeconomic matters. In particular, I distinguish between two kinds (...) of expert shopping, which I call cynical and wishful, and introduce the notion of assisted expert shopping, which occurs when people or organizations shop for experts on behalf of other people. I argue that assisted expert shopping can sometime result in what I call a propagandistic use of expertise. Finally, I critically examine some possible reasons for optimism and find them wanting. I conclude by suggesting that that much of what I said about shopping for macroeconomic experts might also apply mutatis mutandis to other policy-relevant domains of expertise. (shrink)

For quite some time, the research in artificial intelligence has focused on expert systems, because here are to be found practical applications at the experimental stage which may soon become widespread. This focus makes more pressing the need to link the debate about the fundamental efficiency of artificial intelligence with those activities that aim at the application of specialized expert systems. In this paper, I begin by considering the stages and the development of human expertise. As a frame (...) of reference I propose a polar dialectic model of the development of human acting and thinking that explicitly deals with the interplay of calculating rationality and intuition. This suggests the use of expert systems as decision aids particularly in the field of maintenance work on the shop-floor. With regard to this case, some theses concerning the human-centred shaping of technology and work are presented. (shrink)

In the BBC show, The Repair Shop, members of the public bring their cherished but crumbling possessions into a workshop populated by expert craftspeople, who carry out restorations. These objects arrive as treasured possessions, which, despite their dilapidated state, still hold memories and meaning for their owners, albeit memories that may have faded as the object itself has aged. Something magical seems to take place after the objects are restored, however. The restored objects seem to reanimate and revive the (...) memories that their owners have invested in them. How is it possible that this restoration can bring memories held by the objects back to life? What is special about The Repair Shop restoring objects to their former glory? We outline two ways in which objects can be evocative and embody emotion, memory, and meaning. We then outline the ways in which the restoration of these objects to something like their original form can improve scaffolded recall and bring memories back to life. For one class of evocative objects, the restoration enhances recall by reinstating details from the context in which the memories were encoded. For the second class of evocative objects, their restoration affords an imaginative connection to the past, which enables them to become powerful focal points of memory and shared narratives. In effect, The Repair Shop seems to work not only as a repair shop of objects but as a repair shop of memory too. (shrink)

"The world's leading expert on the unconscious mind reveals the hidden mental processes that secretly govern every aspect of our behavior. For more than three decades, Dr. John Bargh has been conducting revolutionary research into the unconscious mind--not Freud's dark, malevolent unconscious but the new unconscious, a helpful and powerful part of the mind that we can access and understand through experimental science. Now Dr. Bargh presents an engaging and enlightening tour of the influential psychological forces that are at (...) work as we go about our daily lives--checking a dating app, holding a cup of hot coffee, or getting a flu shot. Dr. Bargh takes you into his labs at New York University and Yale where his ingenious experiments have shown how the unconscious guides our actions, goals and motivations in areas like race relations, parenting, business, consumer behavior, and addiction. He reveals the pervasive influence of the unconscious mind on who we choose to date or vote for, what we buy, where we live, how we perform on tests and in job interviews, and much more. Before You Know It is full of surprising and entertaining revelations as well as tricks to help you remember to-do items, shop smarter, and sleep better. Before You Know It will profoundly change the way you understand yourself by introducing you to a fascinating world only recently discovered, the world that exists below the surface of your awareness and yet is the key to unlocking new ways of thinking, feeling and behaving."--Jacket.

Profound changes in world markets are resulting in conflict between traditional structures of production and new market requirements. The right answers to this challenge are heavily disputed. One option is to replace human work still further by artificially intelligent technology without changing basic structures of production. In contrast to this strategy, alternative production concepts seek to combine the unique human capabilities of perception, evaluation and decision making in unstructured situations with appropriately designed computer systems. Empirical evidence from the use of (...) NC technology indicates that sensual experience and practical knowledge are necessary ingredients rather than disappearing residuals of efficient production. By far their tacit dimension does not allow complete transformation into objectified, scientific knowledge. In the field of metal cutting it is the skilled workers themselves who constitute the primary source of productivity. In order to overcome their traditionally problematic and uncomfortable working situation, shop-floor programming methods have been developed that are adapted to their concrete and graphic mode of thinking and acting. These allow workers to make their own efficient NC programs, thus maintaining their practical competence. This paper illustrates a necessary new perspective in system design: away from developing computer programs for imitating and replacing human expertise and towards designing computers as a useful tool for human experts.

Despite its aesthetic appeal, the Iranian resort Majara is poised to be a sore point among local residents. Looking at the 200 vibrant oddly-shaped domes might make you feel you’re on a Wes Anderson movie set.The Majara Residence overlooking the Persian Gulf offers homes and resort-like accommodation, complete with cafes, restaurants, souvenir shops, tourist information, a prayer room, laundry, storage and more. Located at Hormuz (or Ormuz) Island, a historic port off the southern coast of Iran, the project is designed (...) to attract tourists to the small island and serve as an alternative to high-rise developments traditionally used to house visitors. Presence in Hormuz 2 is a series of urban development projects designed by the Tehran-based ZAV Architects. Majara (which means adventure) is the second phase of this multipurpose cultural residence, aimed at binding together the lives of local people and visitors culturally and economically. On the verge of opening, this project has been heavily criticised by environmental activists and urban experts citing ecological, economic, cultural and social concerns. Such projects have made locals mere servants in service of investors, which impedes the enhancement of their quality of life. (shrink)

This paper aims to investigate the effect of gamification in engaging and motivating consumers for online shopping and also the use of gamification to enhance sales. Moreover, this study has also explored the ethical concerns in gamified marketing. This is a qualitative study to investigate the effect of gamification during online shopping and the ethical issues involved in gamified marketing. Semi-structured interviews with ten gamification experts are conducted and analyzed through NVivo. The themes that emerged from qualitative analysis (...) are the applicability of gamification in online retail, consumer experiences in gamified retail, and ethics and challenges in gamification. Semantic analysis is performed, and as per the viewpoint of the gamification experts, it was found that the perception of ethics in gamification is negative, which shows that there are many unethical practices in gamified marketing. This paper shows that by focusing on every relational aspect of consumer engagement, retailers can build trust and retain their most valuable stakeholders — the customers, thereby addressing the crucial negative concerns of gamified marketing. This research is one of its types to explore the significant ethical issues that affect consumers in the retail context. The undertaking of this study in an emerging economy adds further insight into gamified retail literature by generalizing the applicability of gamified studies across geographic contexts. (shrink)

This book describes how one can use The Scientific Method to solve everyday problems including medical ailments, health issues, money management, traveling, shopping, cooking, household chores, etc. It illustrates how to exploit the information collected from our five senses, how to solve problems when no information is available for the present problem situation, how to increase our chances of success by redefining a problem, and how to extrapolate our capabilities by seeing a relationship among heretofore unrelated concepts.One should formulate (...) a hypothesis as early as possible in order to have a sense of direction regarding which path to follow. Occasionally, by making wild conjectures, creative solutions can transpire. However, hypotheses need to be well-tested. Through this way, The Scientific Method can help readers solve problems in both familiar and unfamiliar situations. Containing real-life examples of how various problems are solved — for instance, how some observant patients cure their own illnesses when medical experts have failed — this book will train readers to observe what others may have missed and conceive what others may not have contemplated. With practice, they will be able to solve more problems than they could previously imagine.In this second edition, the authors have added some more theories which they hope can help in solving everyday problems. At the same time, they have updated the book by including quite a few examples which they think are interesting. (shrink)

Work is fundamental to human society and modern organizations, and consequently has been central to the thinking of major social theorists and social science disciplines. This book offers a 'one-stop-shop' guide to classical and contemporary perspectvies of work written by leading international experts. Schools covered include: Weberian, Marxian, Durkheimian, feminist, neo-classical economics, institutional economics, ethics, Foucauldian, postmodernist, organizational sociology and economic sociology. Each chapter traces the origins of the theoretical school, reviews seminal contributions,and considers major criticisms of the approach. In (...) addition, the book features a section on key aspects of work - professions, technology, identity and globalisation - to which these theories have been applied. The book makes a major contribution in a number of ways: · Provides systematic coverage of major social and economic theories and the way they aid our understanding of work;· Includes a section of chapters that consider, in an applied way, how social theories have helped the analysis of key substantive areas of work;· Includes contributions from leading academics from both Europe and the USA; · Each chapter can be read as free-standing summary of a particular school of theoretical approach;· In addition, the introductory and concluding chapters examine themes cross-cutting the other chapters in the book.It is an essential text for academics and advanced students concerned with the sociology of work, management, and organization studies.

Turkey has passed the import substitution economic model to a new model of the economy called open out since 1980. Along with the neoliberal policies implemented, the process of integration with the global economy has begun. The incomes of the religious people who cannot be excluded from the effects of this articulation also increased and their consumption behaviors has changed. On the other hand, some transport elements, especially the media, have enabled consumption codes to reach different segments. The new values (...) emerged in this process also caused transformations in individual consumption trends. In this study, the "Scale of Consumption Dynamics" (SCD) was developed in order to identify the trends of consumption of devotees and to find out how they changed. Quantitative research approach was adopted in the study and the datas were collected by face-to-face survey technique. The individuals included in our sample were selected by quota sampling. In this study, an expression pool was created as a result of literature review, expert opinion consultation, brainstorming with academicians and observations. The validity and reliability analysis of the scale was made using different statistics through the SPSS program. As a result of these steps, the dimensions of the scale consisting of 16 items and 3 dimensions are called "showy consumption", "wasteful consumption" and "religious priority consumption". Summary: The first studies on consumption history and sociology belong to Marx, Weber, Veblen and Simmel. In these studies consumption is examined as a part of production process and consumption forms were investigated as a social class aspect. Consumption phenomenon was later studied under critical approach (Frankfurt School) with Adorno, Max Horkheimer, Herbert Marcuse and Erich Fromm’s theories. Theorists at Frankfurt School study how social structure steers individuals to consumption. After the 1970’s, the meaning of consumption phenomenon has changed. There are studies by Jean Baudrillard, Mike Featherstone, George Ritzer, and Zygmunt Bauman on changing phenomenon of consumption. It is widely believed that modern consumption phenomenon was originated in the USA after the World War II. After the war Keynesian economic policies and Fordist consumption forms later influenced other Western nations. After 1950’s and 1960’s mass consumption was initiated in the USA and except very poor sections of the nations, other social classes, it started to spread out in Europe, the USA, and other countries. In 1970’s and 1980’s, it has merged with individuals’ identity definitions. After 1980’s in Turkey a new economic policy instead of import substitution was adopted. In application along with neo liberal policies, Turkey started to integrate to the rest of the World. Religious people as well influenced these changes and their incomes have increased along with their consumption habits. In addition to media, some other forms of communication channels have carried new consumption habits to other sections of the society. With the increased effects of mass communication media, new social sections have emerged and their cultural characteristics have become the norms of the whole society. A new values created in this process also transformed the consumption habits. In this article, in order to assess consumption habits of religious people as it is now and to understand which direction these habits evolve, Consumption Dynamics Scale (CDS) has been developed. Scales are widely used when a researcher tries to identify and measure respondents’ feelings and ideas on a subject matter. There are different scales used in social sciences such as Thurstone, Likert, Guttman, and Bogardus that are among the most widely used ones. A Likert Type scale has been used in this study. In the first phase of the study and pilot study 5 point Likert scale and in the second phase of the study 10 point Likert scales was used to collect the data. We could not come across with any study in the literature on investigating consumption characteristics Dynamics of individuals with a formal religious education. In the study, quantitative research method has been adopted and the research data has been collected with face to face administration of the survey instrument. The scale development phase lasted about 6 months from August, 2016. Based on 3% error rate, we determined to sufficient sample size as 516, yet we reached 600 individuals and end up with 563 usable responses. Sample has been determined with quota sampling methodology. We formed a pool of statements based on literature review, expert opinion, brain storming with academicians. 49 questions have been selected from the question pool where 93 questions were found, then they are merged, some questions are changed or totally eliminated and final 30 questioned questionnaires made ready for pilot study. Two pilot studies have been carried out. In the first pilot study, 47 people are reached and 30 questions with Likert scales have been administered. In the second phase of the study, 10 point Likert scales with 57 questions has been given to 54 individuals. After pilot studies, data was analyzed with SPSS 20 version and 32 questioned final survey instrument has been formed. In order to check sufficiency of data set for Factor Analysis Kaisser-Meyer-Olkin (KMO) test and the relationships among variables Bartlett test were used. Sample composed of 563 responses revealed significant results (3358,808, p=0,000) and KMO test revealed (KMO=0,812) value. After expletory factor analysis, factor loading less than 0,40 were deleted from the scale. Hence the final structure is composed of 29 questions with 8 different factors. The reliability of scales were calculated with Cronbach Alfa analysis separately for each dimension. After reliability analysis, items with 0,60 and less reliability score were taken out from the scales. Finally 16 items were made up 3 dimensions namely “ostentatious consumption”, “wasteful consumption”, and “religious priority consumption”. The items in Factor 1 are related with luxury, fashion and statue, in Factor 2 desire to make more shopping, purchase without need, advertisement and showcase, and factor 3 religious sensitive reference focus and religion first purchasing are decided as appropriate names. Based on the analysis, measurement was decided valid and sound. Therefore, this study is believed to contribute significantly to the existing literature. (shrink)

Sustainability has become paramount in society and retail. Therefore, this study aims to compare the environmental sustainability of brick‐and‐mortar retail and e‐commerce. A literature review identifies various factors, such as buildings, shopping trips, order bundling, returns, packaging, transport and logistics, and environmentally conscious behavior, that determine the channel that is superior in terms of environmental sustainability. While these factors are context‐specific and depend on several actors (e.g., consumers, retailers, and logistics service providers), most studies consider e‐commerce to be more (...) environmentally friendly than purchases from brick‐and‐mortar stores. However, this review demonstrates that most previous studies have focused on objective criteria (e.g., CO2). Therefore, to reflect the importance of consumers' perspectives on channel choice, we conducted four empirical studies that provide insights into the perceived environmental sustainability of each channel. In contrast to experts' views, consumers perceive e‐commerce as less sustainable than brick‐and‐mortar retailing. Hence, online retailers should improve their communication strategies and highlight the potential environmental advantages of e‐commerce and omni‐channel retailing. Brick‐and‐mortar retailers are advised to reduce the environmental damage they cause and encourage their customers to act in an eco‐friendly manner. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Navigating Intersex Healthcare: My OdysseyCynthiaI was born in 1965 with what the medical community called “ambiguous genitalia.” My initial announcement as a boy was called into question upon closer assessment of my atypical anatomy by medical specialists at a children’s hospital in Chicago. That team of medical experts included a pediatric urologist and a pediatric endocrinologist, as well as a prominent pediatric surgeon, who was at that time presiding (...) president of the relatively newly established American Pediatric Surgeons Association. I have wondered over the years whether, or to what extent, that status and position had any important impact on the unfolding of my medical case.Just over 100 days after my birth, I was surgically and socially reassigned female, and renamed Cynthia. My mother and physician father, ages 25 and 30, respectively, with two young sons at home, did the best they could to move ahead in life as a young family. Part of our family story is that my unusual birth contributed to my parents’ decision to move away from Chicago, where both of my parents had been raised and wanted to settle, and where my father had many professional opportunities. We relocated to Southern California to make a “fresh start” where no one would know the dark secret too terrible to be shared with any beyond a small circle of close friends and family. It would never be talked about openly.With the exception of the rare and dreaded occasions of medical appointments with my primary care physician, or maybe an endocrinologist to renew hormone prescriptions, my parents chose [End Page E3] to have me travel from our home in San Diego to a clinician in Los Angeles, away from my father’s medical colleagues. This decision was puzzling to me at the time, and maybe more so now. These trips were a source of considerable stress and anxiety, as I had no idea of what to expect; my mother told me only that treatment would “help me get my period started.” I was instructed to tell my friends and teachers that I was taking off school on a weekday to go on a “shopping trip” with my mother. As far as I know, these trips were never discussed at home with my older brothers. I heard years later that my parents disclosed some information about me with my brothers when my parents travelled outside the country. They felt that my brothers should know what had happened to me in the event of a catastrophic accident that might prevent my parents from telling me themselves. I suppose they believed that I wasn’t ready at the time to be told my own life and medical history. I can’t say for sure.I don’t want to judge my parents too harshly for how they handled my medical care. I know that it was an extremely stressful and uncertain time for them, and peer support, which I know now is so vitally important for both parents and young affected individuals like myself, was not made available to us. I never thought to ask about such help, or even consider the idea that anyone else would be in a similar situation like mine. I don’t think I would have been even remotely comfortable or willing to discuss it openly at that point.In my early twenties, I had to face another milestone in my journey and in my interactions with the medical community. I had yet to have the vaginoplasty I was told I “needed.” There was no discussion as to whether or not I wanted it or not. It just had to be done, and I was aware of the limitations I had at this vulnerable time in my life when my peer group was sexually active and I was not. My awareness of the obstacle posed by my difference made me avoid the topic of dating; it was difficult even to think about the possibility of a romantic relationship. I put it out of my mind, but I knew that it was a significant concern for my parents. My physician father did most of the prodding to get me to acknowledge the reality... (shrink)

Time of (...) the Magicians, originally published in German in 2018 as Zeit der Zauberer, convincingly demonstrates that this feat can indeed be accomplished. However, it may be achievable only by the rare expert who, like Wolfram Eilenberger, combines a thoroughgoing knowledge of the field, an unstinting commitment to recreating a public forum for philosophy, and a gift for the exposition—and dramatization—of philosophical debates, the broader circumstances in which they took place, and the motivations and aims of those who participated in them.The book, stylishly translated by Shaun Whiteside, begins by plunging us into the middle of things. Eilenberger provides snapshots of what his four focal thinkers were up to in 1929, before backtracking, in subsequent chapters, to cover key events in the decade that brought them to this point. Then, in the epilogue, he briefly sketches their post-1929 lives and careers. The book's readability is further enhanced by the way the text is broken up into short sections with eye-catching titles ("A Hut of One's Own," "Existential Health Check," "Self-Fashioning through Openness").The opening pages center on June 1929, when Ludwig Wittgenstein, having previously renounced his portion of his family's fortune and taught for several years at primary schools in rural Austria, undertook an oral defense of his doctoral thesis at the University of Cambridge at age forty. Wittgenstein's "thesis" just so happened to be Tractatus Logico-Philosophicus, the influential, sometimes gnomic book he had published in 1921; and at the conclusion of the defense, the candidate is rumored to have said to his examiners, Bertrand Russell and G. E. Moore, "Don't worry, I know you'll never understand it."In fact, as Eilenberger discusses in a later chapter, by 1929 Wittgenstein's own thinking was no longer where it had been when he wrote the Tractatus. The [End Page 492] philosopher's primary concern had shifted away from identifying the logical structure of meaningful propositions; instead, he had become interested in how meaning emerges from the way language is used in particular, concrete contexts. Apropos the evolving nature of Wittgenstein's ideas, one of the funniest parts of the book describes the philosopher's meetings with members of the Vienna Circle, a group that, in seeking to reorient philosophy around the natural sciences, had come to see the Tractatus as a touchstone for their work. During his first meeting with the group, in 1927, Wittgenstein, instead of talking shop, recited poems by Indian poet Rabindranath Tagore, standing with his back turned to the audience. Later discussions did involve philosophy, but eventually, as Eilenberger puts it, although the "Vienna Circle had hoped for something that coincided with their ideal of objective research," they "were instead left to grapple with an extremely idiosyncratic style of thinking that, in both execution and results, seemed directly contrary to it" (p. 274).Meanwhile, a few months prior to Wittgenstein's defense of a thesis that no longer reflected his real tendencies of mind, two of Eilenberger's other focal thinkers, Ernst Cassirer and Martin Heidegger, engaged in a much-anticipated public debate at the Grand Hôtel Belvédère in Davos, Switzerland. When he first mentions it, Eilenberger furnishes just enough detail to whet readers' curiosity about this epochal contest between the eminent neo-Kantian Cassirer, whose reputation for encyclopedic erudition had just been sealed by the publication of the final volume of his masterwork, The Philosophy of Symbolic Forms, and the considerably younger Heidegger, a one-time student of Edmund Husserl who had made a radical departure from Husserlian phenomenology in Being and Time.By the time readers return to the debate, some three hundred pages later, Eilenberger has provided a decade's worth of historical context, which casts a...

The article examines the issues of modern trends in the development of small business in the Republic of Kalmykia. One of these trends is entrepreneurship, which actively uses ethnic, national components in its line of business. The purpose of the article is to study the ethno-economic aspects of modern entrepreneurship in Kalmykia. The main research method is an expert survey. A total of 12 experts were interviewed. The study was conducted in May-June 2020 in Elista. As experts, restaurateurs or (...) owners of national cuisine cafes, ateliers, clothing manufacturers, representatives of the tourism business, manufacturers of souvenir products, owners of souvenir shops, manufacturers of ethnic furniture, etc. Experts note the popularity and demand for ethnic goods, handicrafts in the segment of ethnic fashion, ethnic design. And also services of ethno-tourism, ethno-restaurants, which testifies to the prospects of ethno-business and ethno-entrepreneurship in the republic. Active revival of Buddhism, restoration, development of national culture, natural resources make Kalmykia especially attractive for tourists. However, one of the problems in the development of ethnic entrepreneurship is the fact that there are very few masters of national instruments, masters of making complex souvenirs. An expert survey has shown that the development of ethnic entrepreneurship is an important resource for economic development in Kalmykia. (shrink)

Systems, machines and organisation of forms developed in the Engineering and Manufacturing sectors frequently lay the basis for systems design philosophy at a general level. An analysis of technological change in these sectors reveals that the resultant deskilling is not limited to the shop floor and is now spreading to intellectual work. The impact of ‘machine based systems’ on designers is explored in some detail and suggests the need for alternatives which are based on ‘human centred systems’. Some attempts to (...) design sub-systems are described. (shrink)

Artificial intelligence and robotics have increasingly been adopted in agri-food systems—from milking robots to self-driving tractors. New projects extend these technologies in an effort to automate skilled work that has previously been considered dependent on human expertise due to its complexity. In this paper, we draw on qualitative research carried out with farm managers on apple orchards and winegrape vineyards in Aotearoa New Zealand. We investigate how agricultural managers’ perceptions of future agricultural automation relates to their approach to expertise, or (...) the degree to which they think specialised skills and knowledge are required to perform agricultural work on their orchards and vineyards. Our research generates two insights: the perceived potential for work to be automated is related to the degree to which it is seen to require technical or embodied expertise, with technical expertise being more automatable; and, while embodied expertise is perceived to be more difficult to automate, it is sometimes attributed more exclusively to those in positions of power, such that embodied expertise can be highly valued while the majority of embodied work is viewed as non-expert and thus automatable. Our analysis illustrates that a robot can be an expert when expertise is technical. It also shows variability in the conceptualization of skilled or unskilled work, and that those conceptualizations can set the stage for the future effects of new technologies. This generates new insights into the conditions under which automation might reproduce existing inequalities in agriculture, and also raises new questions about responsibility in the context of automation.

Studies in the psychology of visual expertise have tended to focus on a limited set of expert domains, such as radiology and athletics. Conclusions drawn from these data indicate that experts use parafoveal vision to process images holistically. In this study, we examined a novel, as-of-yet-unstudied class of visual experts—architects—expecting similar results. However, the results indicate that architects, though visual experts, may not employ the holistic processing strategy observed in their previously studied counterparts. Participants (n = 48, 24 architects, (...) 24 naïve) were asked to find targets in chest radiographs and perspective images. All images were presented in both gaze-contingent and normal viewing conditions. Consistent with a holistic processing model, we expected two results: (1) architects would display a greater difference in saccadic amplitude between the gaze- contingent and normal conditions, and (2) architects would spend less time per search than an undergraduate control group. We found that the architects were more accurate in the perspectival task, but they took more time and displayed a lower difference in saccadic amplitude than the controls. Our research indicates a disjunctive conclusion. Either architects are simply different kinds of visual experts than those previously studied, or we have generated a task that employs visual expertise without holistic processing. Our data suggest a healthy skepticism for across-the-board inferences collected from a single domain of expertise to the nature of visual expertise generally. More work is needed to determine whether holism is a feature of all visual expertise. (shrink)

In attempting to provide protection to individuals and communities, childhood immunization has benefits that far outweigh disease risks. However, some parents decide not to immunize their children with some or all vaccines for reasons including lack of trust in governments, health professionals, and vaccine manufacturers. This article employs a theoretical analysis of trust and distrust to explore how twenty-seven parents with a history of vaccine rejection in two Australian cities view the expert systems central to vaccination policy and practice. (...) Our data show how perceptions of the profit motive generate distrust in the expert systems pertaining to vaccination. Our participants perceived that pharmaceutical companies had a pernicious influence over the systems driving vaccination: research, health professionals, and government. Accordingly, they saw vaccine recommendations in conflict with the interests of their child and “the system” underscored by malign intent, even if individual representatives of this system were not equally tainted. This perspective was common to parents who declined all vaccines and those who accepted some. We regard the differences between these parents—and indeed the differences between vaccine decliners and those whose Western medical epistemology informs reflexive trust—as arising from the internalization of countering views, which facilitates nuance.

Athletes sometimes describe “being in the zone,” as a time when their actions flow effortlessly and flawlessly without the guidance of thought. But is it true that athletes don't think when performing at their best? Numerous studies (such as Beilock et al. 2004, 2007 Ford et al 2005, Baumeister 1984, Masters 1992, Wulf & Prinz 2001, Beilock & DeCaro, 2007). However, I aim to argue that because even highly‐practiced skills can remain in part under an expert athlete's conscious control, (...) thinking does not hinder expert performance. (shrink)

Projections of future climate change cannot rely on a single model. It has become common to rely on multiple simulations generated by Multi-Model Ensembles (MMEs), especially to quantify the uncertainty about what would constitute an adequate model structure. But, as Parker points out (2018), one of the remaining philosophically interesting questions is: “How can ensemble studies be designed so that they probe uncertainty in desired ways?” This paper offers two interpretations of what General Circulation Models (GCMs) are and how MMEs (...) made of GCMs should be designed. In the first interpretation, models are combinations of modules and parameterisations; an MME is obtained by “plugging and playing” with interchangeable modules and parameterisations. In the second interpretation, models are aggregations of expert judgements that result from a history of epistemic decisions made by scientists about the choice of representations; an MME is a sampling of expert judgements from modelling teams. We argue that, while the two interpretations involve distinct domains from philosophy of science and social epistemology, they both could be used in a complementary manner in order to explore ways of designing better MMEs.

What kind of reasons for belief are provided by the testimony of experts? In a world where we are often inundated with fake news, misinformation, and conspiracy theories, this question is more pressing than ever. A prominent view in the philosophical literature maintains that the reasons provided by experts are preemptive in that they normatively screen off, or defeat, other relevant reasons. In this paper, I raise problems for this conception of expertise, including a wholly new one that I call (...) the Problem of the Predatory Expert, which targets both original versions of preemption as well as new, modified ones that aim to avoid some of the standard objections.

Based on a qualitative study about expert musicianship, this paper distinguishes three ways of interacting by putting them in relation to the sense of agency. Following Pacherie, it highlights that the phenomenology of shared agency undergoes a drastic transformation when musicians establish a sense of we-agency. In particular, the musicians conceive of the performance as one single action towards which they experience an epistemic privileged access. The implications of these results for a theory of collective intentionality are discussed by (...) addressing two general questions: When several individuals share an intention, does this fact secure plural self-knowledge? And is it possible to have non-observational knowledge about a collective action? It is claimed that the results drawn from the study about expert musicianship supports negative answers to both questions. (shrink)

Dreyfus and Dreyfus’ influential phenomenological analysis of skill acquisition proposes that expert performance is guided by non-cognitive responses which are fast, effortless and apparently intuitive in nature. Although this model has been criticised for over-emphasising the role that intuition plays in facilitating skilled performance, it does recognise that on occasions a form of ‘detached deliberative rationality’ may be used by experts to improve their performance. However, Dreyfus and Dreyfus see no role for calculative problem solving or deliberation when performance (...) is going well. In the current paper, we draw on empirical evidence, insights from athletes, and phenomenological description to argue that ‘continuous improvement’ among experts is mediated by cognitive control in three distinct sporting situations. We conclude by arguing that Sutton et al. Journal of the British Society for Phenomenology, 42, 78–103 ‘applying intelligence to the reflexes’ approach may help to elucidate the process by which expert performers achieve continuous improvement through analytical/mindful behaviour during training and competition.

What occurs in the mind of an expert who is performing at their very best? In this paper, I survey the history of debate concerning this question. I suggest that expertise is neither solely a mastery of the automatic nor solely a mastery of intelligence in skilled action control. Experts are also capable of performing automatic actions intelligently. Following this, I argue that unconscious-thought theory (UTT) is a powerful tool in coming to understand the role of executive, intelligent action (...) control in the fluidly automatic performance of expertise. Relying on a body of empirical evidence concerning the cognitive structures and perceptual strategies employed by experts, I show that the realm of skilled action is an ideal environment within which the powers of unconscious cognitive processing can have positive effects on action. I conclude that experts rely upon unconscious thinking in the production of intelligently automatic skilled actions. (shrink)

In light of the widespread use of algorithmic (intelligent) systems across numerous domains, there is an increasing awareness about the need to explain their underlying decision-making process and resulting outcomes. Since oftentimes these systems are being considered as black boxes, adding explanations to their outcomes may contribute to the perception of their transparency and, as a result, increase users’ trust and fairness perception towards the system, regardless of its actual fairness, which can be measured using various fairness tests and measurements. (...) Different explanation styles may have a different impact on users’ perception of fairness towards the system and on their understanding of the outcome of the system. Hence, there is a need to understand how various explanation styles may impact non-expert users’ perceptions of fairness and understanding of the system’s outcome. In this study we aimed at fulfilling this need. We performed a between-subject user study in order to examine the effect of various explanation styles on users’ fairness perception and understanding of the outcome. In the experiment we examined four known styles of textual explanations (case-based, demographic-based, input influence-based and sensitivity-based) along with a new style (certification-based) that reflect the results of an auditing process of the system. The results suggest that providing some kind of explanation contributes to users’ understanding of the outcome and that some explanation styles are more beneficial than others. Moreover, while explanations provided by the system are important and can indeed enhance users’ perception of fairness, their perception mainly depends on the outcome of the system. The results may shed light on one of the main problems in explainability of algorithmic systems, which is choosing the best explanation to promote users’ fairness perception towards a particular system, with respect to the outcome of the system. The contribution of this study is reflected in the new and realistic case study that was examined, in the creation and evaluation of a new explanation style that can be used as the link between the actual (computational) fairness of the system and users’ fairness perception and in the need of analyzing and evaluating explanations while taking into account the outcome of the system.

Mental representation has long been central to standard accounts of action and cognition generally, and in the context of sport. We argue for an enactive and embodied account that rejects the idea that representation is necessary for cognition, and posit instead that cognition arises, or is enacted, in certain types of interactions between organisms and their environment. More specifically, we argue that enactive theories explain some kinds of high-level cognition, those that underlie some of the best performances in sport and (...) similar practices (dance, martial arts), better than representational accounts. Flow and mushin (mindfully fluid awareness) are explained enactively to this end. This results in a mutually beneficial analysis where enactivism offers theoretical and practical advantages as an explanation of high performance in sports, while the latter validates enactivism.

The theory of Participatory Discrepancies (or PDs) claims that minute temporal asynchronies (microtiming) in music performance are crucial for prompting bodily entrainment in listeners, which is a fundamental effect of the “groove” experience. Previous research has failed to find evidence to support this theory. The present study tested the influence of varying PD magnitudes on the beat-related body movement behavior of music listeners. 160 participants (79 music experts, 81 non-experts) listened to twelve music clips in either Funk or Swing style. (...) These stimuli were based on two audio recordings (one in each style) of expert drum and bass duo performances. In one series of six clips, the PDs were downscaled from their originally performed magnitude to complete quantization in steps of 20%. In another series of six clips, the PDs were upscaled from their original magnitude to double magnitude in steps of 20%. The intensity of the listeners’ beat-related head movement was measured using video-based motion capture technology and Fourier analysis. A mixed-design four-factor ANOVA showed that the PD manipulations had a significant effect on the expert listeners’ entrainment behavior. The experts moved more when listening to stimuli with PDs that were downscaled by 60% compared to completely quantized stimuli. This finding offers partial support for PD theory: PDs of a certain magnitude do augment entrainment in listeners. But the effect was found to be small to moderately sized, and it affected music expert listeners only. (shrink)

This article explores the social frameworks guiding expert and nonexpert perspectives on medicines safety in the U.K. Scientific experts from the Committee on the Safety of Medicines and the Medicines Commission were interviewed, and three nonexpertgroups, including patients and health professionals, were studied by the administration of questionnaires and focused group discussions. The research examined to what extent these groups subscribed to technocratic or democratic approaches to medicines regula tion and how this might be related to values toward technological (...) risk. The results reveal that there is substantial divergence between expert and nonexpert perspectives on medicines regulation, and that this derives as much from value differences as from any informational deficits. However, there seems to be some scope for shared values between some experts and some nonexperts, especially as regards state secrecy. The article concludes by discussing how those values could be used to foster a new "social contract of expertise" in which scientists are more democratically accountable and patients take more responsibility in governing medical risks.

ABSTRACTIn everyday situations, people regularly receive information from large groups of people and from single experts. Although lay opinions and expert opinions have been studied extensively in isolation, the present study examined the relationship between the two by asking how many laypeople are needed to counter an expert opinion. A Bayesian formalisation allowed the prescription of this quantity. Participants were subsequently asked to assess how many laypeople are needed in different situations. The results demonstrate that people are sensitive (...) to the relevant factors identified for determining how many lay opinions are required to counteract a single expert opinion. People's assessments were fairly good in line with Bayesian predictions. (shrink)

We investigated the understanding of causal systems categories—categories defined by common causal structure rather than by common domain content—among college students. We asked students who were either novices or experts in the physical sciences to sort descriptions of real-world phenomena that varied in their causal structure (e.g., negative feedback vs. causal chain) and in their content domain (e.g., economics vs. biology). Our hypothesis was that there would be a shift from domain-based sorting to causal sorting with increasing expertise in the (...) relevant domains. This prediction was borne out: The novice groups sorted primarily by domain and the expert group sorted by causal category. These results suggest that science training facilitates insight about causal structures. (shrink)

This study investigates the negative influence of consumer’s perceptions of online retailer’s deceptive practices on consumer’s relational variables. Also, the moderating role of product type, consumer’s attitude toward the Internet, and consumer’s demographics in the deception-relational outcomes link is considered. Data from 398 online consumers revealed that satisfaction totally mediated the influence of deception on loyalty. Furthermore, the deception-satisfaction link was moderated by all the hypothesized variables. Interestingly, a direct effect of deception on loyalty was found among more educated consumers, (...) consumers who had a more positive attitude toward the Internet and consumers who had purchased a physical product. Implications for theory and management are discussed. (shrink)

Background While most countries that allow abortion on women’s request also grant physicians a right to conscientious objection (CO), this has proven to constitute a potential barrier to abortion access. Conscientious objection is regarded as an understudied phenomenon the effects of which have not yet been examined in Germany. Based on expert interviews, this study aims to exemplarily reconstruct the processes of abortion in a mid-sized city in Germany, and to identify potential effects of conscientious objection. Methods Five semi-structured (...) interviews with experts from all instances involved have been conducted in April 2020. The experts gave an insight into the medical care structures with regard to abortion procedures, the application and manifestations of conscientious objection in medical practice, and its impact on the care of pregnant women. A content analysis of the transcribed interviews was performed. Results Both the procedural processes and the effects of conscientious objection are reported to differ significantly between early abortions performed before the 12th week of pregnancy and late abortions performed at the second and third trimester. Conscientious objection shows structural consequences as it is experienced to further reduce the number of possible providers, especially for early abortions. On the individual level of the doctor-patient relationship, the experts confirmed the neutrality and patient-orientation of the vast majority of doctors. Still, it is especially late abortions that seem to be vulnerable to barriers imposed by conscientious objection in individual medical encounters. Conclusion Our findings indicate that conscientious objection possibly imposes barriers to both early and late abortion provision and especially in the last procedural steps, which from an ethical point of view is especially problematic. To oblige hospitals to partake in abortion provision in Germany has the potential to prevent negative impacts of conscientious objection on women’s rights on an individual as well as on a structural level.

Mizrahi :57–79, 2013; Inform Logic 36:238–252; Argumentation 32:175–195, 2018) claims that AEO are weak arguments by presenting two independent arguments. The first argument is that AEO are weak arguments because (...) empirical studies show that expert opinions p do not make p significantly more likely to be true. The second argument is that AEO are weak arguments because empirical studies show that expert opinions are susceptible to the kinds of cognitive biases that novice opinions are susceptible to. In this paper, I intend to argue that Mizrahi’s two arguments both fail because of inconsistency, irrelevance, and insufficiency. Nevertheless, Mizrahi’s arguments help to evaluate AEO better by expanding the relevant critical questions. (shrink)

Memory for spatial location is typically biased, with errors trending toward the center of a surrounding region. According to the category adjustment model, this bias reflects the optimal, Bayesian combination of fine-grained and categorical representations of a location. However, there is disagreement about whether categories are malleable. For instance, can categories be redefined based on expert-level conceptual knowledge? Furthermore, if expert knowledge is used, does it dominate other information sources, or is it used adaptively so as to minimize (...) overall error, as predicted by a Bayesian framework? We address these questions using images of geological interest. The participants were experts in structural geology, organic chemistry, or English literature. Our data indicate that expertise-based categories influence estimates of location memory—particularly when these categories better constrain errors than alternative categories. Results are discussed with respect to the CAM. (shrink)

This article reflects on the author's modest experience as an expert witness in two trials: Osheroff vs. Greenspan (1983), and In the Matter of Baby K (1994). Bioethicists' expertise as scholar-teachers and consultants on particular issues merits qualification by judges as expert witnesses. The article argues that a different kind of expertise – strong moral advocacy – is required to be an effective expert witness. The major lessons of expert witnessing for the author concern the demands (...) and strains on the bioethicist's role as scholar, teacher, and consultant. The Baby K case is analyzed in some detail, due to its importance for bioethics, ethics consultation, and the testimony of bioethicists on either side of the case. Rules of thumb are offered to guide decisions as to choices regarding expert witnessing, as well as a discussion of the interaction of law and bioethics. (shrink)

This is the full version of the Delphi Report on critical thinking and critical thinking instruction at the post-secondary level.

In 2002, I wrote an editorial in this Journal arguing that it was time to review the structure and function of ethics committees in the USA, Australia and the UK.1 This followed the deaths of Ellen Roche and Jesse Gelsinger, which were at least in significant part due to the poor functioning of research ethics committees in the USA.2 In the case of Ellen Roche, it was the failure to require a systematic review of the existing literature which led to (...) her death. Iain Chalmers and I had previously documented in 1996 the failure of ethics committees to require systematic review.3 In 1998, at the time of revising the previous guidelines and forming the first Australian National Statement on Research Ethics, I made a public submission to the Australian Health Ethics Committee arguing that the new guidelines for RECs should include a person with skills in conducting systematic reviews of the literature and that the requirement to have a religious representative on the committee be replaced with the requirement to have an ethicist. Neither of these changes was made. I argued, ‘It is time to ask whether institutional RECs should be abandoned in favour of expert committees that cover many institutions—suprainstitutional specialist committees. Supraregional specialist ethics committees could specialise—for example, in genetic research, cancer clinical trials, dermatology, respiratory physiology and each of the specialist areas of medical research. An example of such a committee is provided by the Thoracic Society of Australia and New Zealand research ethics committee, which reviews multicentre trials of respiratory drugs’.4 Around that time, I was involved ‘at the coal face’ as Chair of the Department of Human Services Ethics Committee in Victoria. In a public presentation, I arguedThere are two philosophical views of what ethics review is. On the …. (shrink)

For the most part, the Aesthetic Theory of Art—any theory of art claiming that the aesthetic is a descriptively necessary feature of art—has been repudiated, especially in light of what are now considered traditional counterexamples. We argue that the Aesthetic Theory of Art can instead be far more plausibly recast by abandoning aesthetic-feature possession by the artwork for a claim about aesthetic-concept possession by the artist. This move productively re-frames and re-energizes the debate surrounding the relationship between art and the (...) aesthetic. That is, we claim Aesthetic Theory so re-framed suggests that the aesthetic might have a central and substantial explanatory role to play within both traditional philosophical enquiries as well as recent and more empirical enquiries into the psychological and cognitive aspects of art and its practice. Finally, we discuss the directions this new work might take—by tying art theory to investigations of the distinctive sensorimotor capacities of expert artists, their specialized aesthetic conceptual schemata, and the ways these distinctive capacities and schemata contribute to the production of artworks.

Around the world, private and public organizations use software called legal expert systems to compute taxes. This software must comply with the laws they are designed to implement. As such, a bug or an error in a program that leads to tax miscalculations can have heavy legal and democratic consequences. However, increasing evidence suggests that some legal expert systems may not comply with the law. Moreover, traditional software development processes mean that legal expert systems are difficult to (...) adapt to the continuous flow of new legislation. To prevent further software decay and to reconcile these systems with the growing demand for algorithmic transparency, we argue that there is a need for a new development process for legal expert systems. This new system must be built to comply with the law, in particular the GDPR. It must also respect democratic transparency. For these reasons, we present a solution built by lawyers and computer scientists: C atala, a new programming language coupled with a pair programming development process. (shrink)

This paper considers the roles and definitions of expert and lay members of ethics committees, focussing on those given by the National Research Ethics Service which is mandated to review all research conducted in National Health Service settings in the United Kingdom. It questions the absence of a specified position for the ‘professional ethicist’ and suggests that such individuals will often be lay members of ethics committees, their participation being a reflection of their academic interest and expertise. The absence (...) of a specified position for professional ethicists and the concomitant but implicit denial of ethical expertise appear to be an anomalous state of affairs if one considers that the training offered to members of ethics committees is often delivered by academic ethicists. It is suggested that this is based on a misunderstanding of the concept ‘ethical expertise’ and that properly understood the ethicist can assist the work of ethics committees by drawing on their expert knowledge.

Increasing behavioural evidence suggests that expert video game players (VGPs) show enhanced visual attention and visuospatial abilities, but what underlies these enhancements remains unclear. We administered the Poffenberger paradigm with concurrent electroencephalogram (EEG) recording to assess occipital N1 latencies and interhemispheric transfer time (IHTT) in expert VGPs. Participants comprised 15 right-handed male expert VGPs and 16 non-VGP controls matched for age, handedness, IQ and years of education. Expert VGPs began playing before age 10, had a minimum (...) 8 years experience, and maintained playtime of at least 20 hours per week over the last 6 months. Non-VGPs had little-to-no game play experience (maximum 1.5 years). Participants responded to checkerboard stimuli presented to the left and right visual fields while 128-channel EEG was recorded. Expert VGPs responded significantly more quickly than non-VGPs. Expert VGPs also had significantly earlier occipital N1s in direct visual pathways (the hemisphere contralateral to the visual field in which the stimulus was presented). IHTT was calculated by comparing the latencies of occipital N1 components between hemispheres. No significant between-group differences in electrophysiological estimates of IHTT were found. Shorter N1 latencies may enable expert VGPs to discriminate attended visual stimuli significantly earlier than non-VGPs and contribute to faster responding in visual tasks. As successful video-game play requires precise, time pressured, bimanual motor movements in response to complex visual stimuli, which in this sample began during early childhood, these differences may reflect the experience and training involved during the development of video-game expertise, but training studies are needed to test this prediction.

Propositions about the nature of expertise, in general, and expertise in pedagogy, in particular, are discussed. The time needed to develop expertise in teaching and the highly contextual nature of teachers’ knowledge are also discussed. Four theories of teacher development are presented, with an elaboration on the heuristic value of the theory of Dreyfus and Dreyfus (1986). Examples from the pedagogical literature are used to illustrate this theory. The recent research establishing causal relationships between those identified as experts in teaching (...) and their students’ academic achievement is also presented. This research allows those who study expertise in teaching to have a more objective measure for identifying and studying expert pedagogues. (shrink)
