Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error (...) computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)

Bernard Williams thought that philosophy should address real human concerns felt beyond academic philosophy. But what wider concerns are addressed by Ethics and the Limits of Philosophy, a book he introduces as being ‘principally about how things are in moral philosophy’? In this article, we argue that Williams responded to the concerns of his day indirectly, refraining from explicitly claiming wider cultural relevance, but hinting at it in the pair of epigraphs that opens the main text. This was Williams’s solution (...) to what he perceived as the stylistic problem of how to pursue philosophy as cultural critique. Taking the epigraphs as interpretative keys to the wider resonances of the book, we show how they reveal Williams’s philosophical concerns – with the primacy of character over method, the obligation to follow orders, and the possibility of combining truth, truthfulness, and a meaningful life in a disillusioned world – to be recognisably rooted in the cultural concerns of post-war Britain. In the light of its epigraphs, the book emerges as the critique of a philosophical tradition’s inadequacies to the special difficulties of its cultural moment. (shrink)

The HealthyFood program offers members up to 25% cash back monthly on healthy food purchases. In this randomized controlled trial, we tested the efficacy of financial incentives combined with text messages in increasing healthy food purchases among HF members. Members receiving the lowest cash back level were randomized to one of six arms: Arm 1 : 10% cash back, no weekly text, standard monthly text; Arm 2: 10% cash back, generic weekly text, standard monthly text; Arm 3: 10% cash back, (...) personalized weekly text, standard monthly text; Arm 4: 25% cash back, personalized weekly text, standard monthly text; Arm 5: 10 + 15%NET cash back, personalized weekly text, standard monthly text; and, Arm 6: 10 + 15%NET cash back, personalized weekly text, unbundled monthly text. In the 10 + 15%NET cash back, the cash back amount was the baseline 10% plus 15% of the net difference between healthy and unhealthy spending. The generic text included information on HF and healthy eating, while the personalized text had individualized feedback on purchases. The standard monthly text contained the cash back amount. The unbundled monthly text included the amount lost due to unhealthy purchases. The primary outcome was the average monthly percent healthy food spending. Secondary outcomes were the percent unhealthy food spending, and the percent healthy and unhealthy food items. Of the members contacted, 20 opted out, and 2841 met all inclusion criteria. There were no between-arm differences in the examined outcomes. The largest mean difference in percent healthy spending was between Arm 1 and Arm 2, and the largest mean difference in percent unhealthy spending was also between Arm 1 and Arm 2, but no differences were statistically significant after correction for multiple comparisons. None of the tested financial incentive structures or text strategies differentially affected food purchasing. Notably, more than doubling the cash back amount and introducing a financial disincentive for unhealthy purchases did not affect purchasing. These findings speak to the difficulty of changing shopping habits and to the need for innovative strategies to shift complex health behaviors.

Language experience clearly affects the perception of speech, but little is known about whether these differences in perception extend to non-speech sounds. In this study, we investigated rhythmic perception of non-linguistic sounds in speakers of French and German using a grouping task, in which complexity was manipulated. In this task, participants grouped sequences of auditory chimeras formed from musical instruments. These chimeras mimic the complexity of speech without being speech. We found that, while showing the same overall grouping preferences, the (...) German speakers showed stronger biases than the French speakers in grouping complex sequences. Sound variability reduced all participants’ biases, resulting in the French group showing no grouping preference for the most variable sequences, though this reduction was attenuated by musical experience. In sum, this study demonstrates that linguistic experience, musical experience, and complexity affect rhythmic grouping of non-linguistic sounds and suggests that experience with acoustic cues in a meaningful context is necessary for developing a robust grouping preference that survives acoustic variability.

The usefulness of machine learning algorithms has led to their widespread adoption prior to the development of a conceptual framework for making sense of them. One common response to this situation is to say that machine learning suffers from a “black box problem.” That is, machine learning algorithms are “opaque” to human users, failing to be “interpretable” or “explicable” in terms that would render categorization procedures “understandable.” The purpose of this paper is to challenge the widespread agreement about the existence (...) and importance of a black box problem. The first section argues that “interpretability” and cognates lack precise meanings when applied to algorithms. This makes the concepts difficult to use when trying to solve the problems that have motivated the call for interpretability. Furthermore, since there is no adequate account of the concepts themselves, it is not possible to assess whether particular technical features supply formal definitions of those concepts. The second section argues that there are ways of being a responsible user of these algorithms that do not require interpretability. In many cases in which a black box problem is cited, interpretability is a means to a further end such as justification or non-discrimination. Since addressing these problems need not involve something that looks like an “interpretation” of an algorithm, the focus on interpretability artificially constrains the solution space by characterizing one possible solution as the problem itself. Where possible, discussion should be reformulated in terms of the ends of interpretability. (shrink)

While mass spectrometry (MS)‐based quantification of small molecules has been successfully used for decades, targeted MS has only recently been used by the proteomics community to investigate clinical questions such as biomarker verification and validation. Targeted MS holds the promise of a paradigm shift in the quantitative determination of proteins. Nevertheless, targeted quantitative proteomics requires improvisation in making sample processing, instruments, and data analysis more accessible. In the backdrop of the genomic era reaching its zenith, certain questions arise: is the (...) proteomic era about to come? If we are at the beginning of a new future for protein quantification, are we prepared to incorporate targeted proteomics at the benchside for basic research and at the bedside for the good of patients? Here, an overview of the knowledge required to perform targeted proteomics as well as its applications is provided. A special emphasis is placed on upcoming areas such as peptidomics, proteoform research, and mass spectrometry imaging, where the utilization of targeted proteomics is expected to bring forth new avenues. The limitations associated with the acceptance of this technique for mainstream usage are also highlighted. (shrink)

Yoga is a popular and beneficial evidence-based health practice. This book addresses the origins, explores yoga's evolution, and outlines current scientific research as well as contemporary discussions related to the possibilities as well as the politicization of this ancient Indian practice.

In “Missing the Forest for the Trees: Aduhelm, Accelerated Approvals & the Agency,” Dr. Matthew Herder argues that agency capture and politicized discretion drive delays in confirmatory trials of accelerated approval drugs amongst other concerns at US Food and Drug Administration (FDA). In highlighting this important problem and offering nuanced insight into agency workings based in part on interviews with twenty-three unnamed FDA officials and a three-drug case study, Dr. Herder suggests two innovative solutions. However, amidst broader debates balancing agency (...) expertise, data, and delegation, these proposed policy solutions would benefit from more corroborative evidence and consideration of institutional advantages within constitutional limits.

For stakeholders, such as investors and lenders, to appropriately assess a company's financial performance, the reported accounting earnings must closely reflect the economic reality of the organization's financial activity throughout the reporting period. The degree to which reported earnings capture economic reality is called earnings quality. Managers have an ethical obligation to report high quality earnings to interested stakeholders in a timely matter. Accounting research has identified conditions within an organization, such as management compensation contracts and pending litigation that can (...) impact earnings quality. We extend this line of research by exploring whether another characteristic of an organization, gender diversity in senior management, influences the quality of reported earnings. Companies with more women in senior management are found to be more profitable and have higher stock returns after initial public offerings than those with fewer women in the management ranks. Our findings suggest that the improved bottom line for companies with more women senior executives is not produced through the management of earnings or lower quality earnings. Instead, earnings quality is positively associated with gender diversity in senior management. (shrink)

Heart disease is the leading cause of death amongst adult Americans and has recently become a top killer worldwide. The direct costs of cardiovascular disease are projected to triple in the next 20 years, from $272.5 billion to $818.1 billion (Heidenreich et al. 2011). Although there has been a decreased incidence and prevalence of ischemic heart disease over the past several decades in the United States, heart failure remains a major cause of morbidity and mortality. In the United States, approximately (...) 500,000 to 700,000 new cases are identified each year (Lloyd-Jones et al. 2009). Heart failure is now the number one diagnosis leading to hospitalization. As such, it is an increasingly heavy economic burden on .. (shrink)

The impact of 2-year residential fulltime MBA program on students' values was studied using a longitudinal design and data collected over 7 years from a business school in India. Values were measured when students entered the program, and again when they graduated. Sample in Study 1 consisted of 229 students from three consecutive graduating classes. Rank-order or ipsative measure of values was used. Results of matched sample t-tests show that self-oriented values like a comfortable life and pleasure become more important (...) and others-oriented values like being helpful and polite become less important over 2 years. The moderating role of sex and functional specialization are also analyzed. Study 2 used a non-ipsative measure of values and a sample of 138 students from two consecutive graduating classes. Results show that management education enhances self-monitoring and importance of self-oriented values and reduces the importance of others-oriented values. The effect on both sets of values remains significant even after controlling for self-monitoring. (shrink)

What are the limits of language? How can philosophy be brought closer to everyday life? What is a good human being? These were among the questions that philosophers wrestled with in mid-twentieth-century Britain, a period shadowed by war and the rise of fascism. In response to these events, thinkers such as Philippa Foot (originator of the famous trolley problem), Isaiah Berlin, Iris Murdoch, Elizabeth Anscombe, Gilbert Ryle, and J. L. Austin aspired to a new level of watchfulness and self-awareness about (...) language as a way of keeping philosophy true to everyday experience. A Terribly Serious Adventure traces the friendships and the rivalries, the shared preoccupations and the passionate disagreements of some of Oxford's most innovative thinkers. Far from being stuck in their ivory towers, the Oxford philosophers lived. They were codebreakers, diplomats, and soldiers in both World Wars, and they often drew on their real-world experience in creating their greatest works, masterpieces of British modernism original in both thought and style.

In this article I argue that the Critical Kant endorses the claim that God creates the best possible world, and that this claim is best understood as committing him to the view that God creates an infinitely valuable world. Kant’s understudied Critical theory of the best possible world differs significantly from his better-known quasi-Leibnizian pre-Critical account insofar as it uses an axiological rather than ontological metric for the goodness of worlds. The axiological metric introduces unique challenges for a Kantian account (...) of the best possible world. These challenges are in turn resolved via an infinite value interpretation. (shrink)

In this essay, the author presents the Martinican intellectual Edouard Glissant's Poétique de la Relation in a new frame by reading his text as it accomplishes a type of grand-scale theorizing. The notion of Relation in Glissant is followed in its various connections to a Marxian notion of dynamic totality. The Marxian/Hegelian subtext of Poétique is seen as productively revealing for reading Glissant both historically and theoretically. Glissant's theorizing of difference is shown to be an important contribution to contemporary revisions (...) of Marxian-informed thought. (shrink)

The half-century, which is the time that has elapsed since the publication of Wretched of the Earth , seems such a short period when one imagines its author in all his intellectual magnificence, his anguish, and the many details we all know of his short-lived reality. Dare one say, after the concept has long been declared “dead” that we imagine him as having been a live “author”? As I write this, the idea of various notable intellectuals and revolutionary movements could (...) come to mind in order for them to serve as interesting comparisons as we discuss and remember Fanon, his analyses of the colonial aftermath, and his many predictions, both explicit and implicit. However, the “death” of the author is, in fact, as Barthes’ polemical essay showed, a premise that empowers the text in its full potentiality well beyond the deism by which the identity of the author becomes the authority. Here, the liberation of the text joins up the enunciation with its “content” so to speak, or in Barthes’ words, reveals how Fanon “made of his very life a work for which his book was a model.” It is from this idea that I wish to see Fanon as incomparable. The reason to do so does not stem from some esoteric form of admiration, but rather a conviction that Fanon’s narration itself is both indicative and exemplary of a process of thinking that, for me, remains unparalleled in theorizing the role of the intellectual. Such a conviction requires us to read beyond the content of Wretched and be “reborn” in the Barthesian sense as readers. In essence, it is to simply follow the way Fanon himself allows us to actually trace how he dreams of “the native” or “the people” and thus accomplishes an affective leap, arguably, more completely than any other intellectual. This reading is, thus, an invitation to dream – even momentarily – of Fanon. (shrink)

This chapter argues that several aspects of Bernard Williams’s style, methodology, and metaphilosophy can be read as evolving dialectically out of Wittgenstein’s own. After considering Wittgenstein as a stylistic influence on Williams, especially as regards ideals of clarity, precision, and depth, Williams’s methodological debt to Wittgenstein is examined, in particular his anthropological interest in thick concepts and their point. The chapter then turns to Williams’s explicit association, in the 1990s, with a certain form of Wittgensteinianism, which he called ‘Left Wittgensteinianism’. (...) It is shown how this is not a sudden conversion, but the direct product of Williams’s longstanding critical engagement with Wittgenstein’s methodology and metaphilosophy: Williams arrives at this position by envisaging a Wittgensteinianism that thinks in concrete sociohistorical terms, embraces genuine explanation, and relinquishes its insistence on the purity of philosophy. When properly understood, moreover, this critique turns out to be continuous with Williams’s advocacy of a conception of philosophy as a humanistic discipline. Finally, it is shown that Williams inherits from Wittgenstein a certain understanding of how philosophy can help us to live, in particular the therapeutic ambition to liberate us from distortions in our self-understanding by assembling reminders.

There is a dearth of business ethics research on family firms, despite the importance of such firms to the US economy. We answer Vazquez’s call to examine the intersection of family-firm research and business ethics, by investigating whether external auditors assess higher risk of fraud in family firms. We test the contradictory predictions of two dominant theoretical perspectives in family-firm research—entrenchment theory and alignment theory. We conduct an experiment with highly experienced external audit professionals, who assess the risk of fraud (...) and make client acceptance decisions for family firms versus non-family firms with different strength of corporate governance: strong versus weak audit committees. We find that auditors assess the risk of fraud as higher for family firms than for non-family firms, consistent with the predictions of entrenchment theory. Auditors are also less likely to make client acceptance recommendations for family firms. The strength of the AC moderates the family-firm effect, whereby auditors assess family firms with weak ACs to have the highest fraud risk and to be the least desirable audit clients. Our findings suggest that auditors perceive more severe agency conflicts to be present in family firms than in non-family firms, consistent with entrenchment theory, according to which family members may behave opportunistically to extract rents and potentially expropriate the firm’s resources at the expense of minority shareholders.

A comprehensive model of moral development must encompass moral sensitivity, moral reasoning, moral motivation, and moral character. Western models of moral development have often failed to show validity outside the culture of their origin. We propose Karma-Yoga, the technique of intelligent action discussed in the Bhagawad Gita as an Indian model for moral development. Karma-Yoga is conceptualized as made up of three dimensions viz. duty-orientation, indifference to rewards, and equanimity. Based on survey results from 459 respondents from two large Indian (...) organizations, we show that the dimensions of Karma-Yoga are related to moral sensitivity, moral motivation, and moral character.

The relationships between transformational leadership and followers’ karma yoga, spirituality, organizational identification and normative organizational commitment were studied using a sample of 144 teachers of a prominent high school in western India. Spirituality is the goal of all existence according to the Upanishads, and karma yoga is a simple means to enhance spirituality. It was hypothesized that karma yoga enhances spirituality, transformational leadership enhances karma yoga and spirituality, and all the three in turn enhance organizational identification and normative organizational commitment. (...) Results of structural equations analysis shows that transformational leadership enhances followers’ karma yoga; both transformational leadership and karma yoga enhance followers’ oneness with all beings: both transformational leadership and oneness enhance organizational identification; and both karma yoga and organizational identification enhance normative commitment. The implications of transformational leadership addressing both followers’ real needs and organizational interests are discussed. (shrink)

Vedānta is one of the oldest philosophical systems. While there are many detailed commentaries on Vedānta, there are very few mathematical descriptions of the different concepts developed there. This article shows how ideas from theoretical computer science can be used to explain Vedānta. The standard ideas of transition systems and modal logic are used to develop a formal description for the different ideas in Vedānta. The generality of the formalism is illustrated via a number of examples including saṃsāra, Patañjali’s Yogasūtras, (...) karma, the three avasthās from the Māṇḍūkya Upaniṣad and the key difference between advaita and dvaita in relation to mokṣa.

The integration of language production and comprehension processes may be more specific in terms of developmental timing than Pickering & Garrod (P&G) discuss in their target article. Developmental studies do reveal links between production and comprehension, but also demonstrate that the integration of these skills changes over time. Production-comprehension links occur within specific language skills and specific time windows.

I consider theories of gravity built not just from the metric and affine connection, but also other symmetric tensor. The Lagrangian densities are scalars built from them, and the volume forms are related to Cayley’s hyperdeterminants. The resulting diff-invariant actions give rise to geometric theories that go beyond the metric paradigm, and contain Einstein gravity as a special case. Examples contain theories with generalizeations of Riemannian geometry. The 0-tensor case is related to dilaton gravity. These theories can give rise to (...) new types of spontaneous Lorentz breaking and might be relevant for “dark” sector cosmology. (shrink)

This study examined whether transformational leadership would be affected by the predominance of a particular guna in a leader and his or her belief in Karma Yoga. An experiment was conducted using a sample of 110 marketing executives working in a financial services firm in eastern India. A 2 × 2 + 1 factorial design was used to manipulate the three gunas and Karma Yoga. Sattva and rajas were crossed with Karma Yoga to produce four cells, with tamas being the (...) fifth cell. Transformational leadership was the measured variable. Results show that compared to rajas, sattva enhances transformational leadership, whereas tamas reduces it. Further, Karma Yoga enhances transformational leadership when the leader is sattvic, but does not enhance transformational leadership when the leader is rajasic. Results imply that organizations interested in enhancing transformational leadership should develop s attvic qualities in their managers and encourage them to be duty oriented. (shrink)

People who habituate to stress show a repetition-induced response attenuation—neuroendocrine, cardiovascular, neuroenergetic, and emotional—when exposed to a threatening environment. But the exact dynamics underlying stress habituation remain obscure. The free energy principle offers a unifying account of self-organising systems such as the human brain. In this paper, we elaborate on how stress habituation can be explained and modelled using the free energy principle. We introduce habituation priors that encode the agent’s tendency for stress habituation and incorporate them in the agent’s (...) decision-making process. Using differently shaped goal priors—that encode the agent’s goal preferences—we illustrate, in two examples, the optimising behaviour of agents. We show that habituation minimises free energy by reducing the precision of goal preferences. Reducing the precision of goal priors means that the agent accepts adverse states. Acceptance or tolerance of adverse outcomes may explain why habituation causes people to exhibit an attenuation of the stress response. Given that stress habituation occurs in brain regions where goal priors are encoded, i.e., in the ventromedial prefrontal cortex and that these priors are encoded as sufficient statistics of probability distributions, our approach seems plausible from an anatomical-functional and neuro-statistical point of view. The ensuing formal and generalisable account—based on the free energy principle—further motivate our novel treatment of stress habituation. Our analysis suggests that stress habituation has far-reaching consequences, protecting against the harmful effects of toxic stress, but on the other hand making the acceptability of precarious living conditions and the development of the obese type 2 diabetes mellitus phenotype more likely.

Perceptual grouping is fundamental to many auditory processes. The Iambic–Trochaic Law (ITL) is a default grouping strategy, where rhythmic alternations of duration are perceived iambically (weak‐strong), while alternations of intensity are perceived trochaically (strong‐weak). Some argue that the ITL is experience dependent. For instance, French speakers follow the ITL, but not as consistently as German speakers. We hypothesized that learning about prosodic patterns, like word stress, modulates this rhythmic grouping. We tested this idea by training French adults on a German‐like (...) stress contrast. Individuals who showed better phonological learning had more ITL‐like grouping, particularly over duration cues. In a non‐phonological condition, French adults were trained using identical stimuli, but they learned to attend to acoustic variation that was not linguistic. Here, no learning effects were observed. Results thus suggest that phonological learning can modulate low‐level auditory grouping phenomena, but it is constrained by the ability of individuals to learn from short‐term training. (shrink)

In a study of 205 leader–follower pairs, we investigated the impact of the leader’s values and empathy on followers’ perception of transformational leadership and the effect of transformational leadership on followers’ values and empathy. The moderating effect of leader–follower relationship duration on the effect of transformational leadership on followers’ values and empathy was also investigated. We found that the leader’s values were related to transformational leadership and transformational leadership was related to followers’ values. Over time, the relationship between transformational leadership (...) and followers’ empathy and values became stronger. (shrink)
