It is well known that the appearance of food, particularly its color, can influence flavor perception and identification. However, food studies involving the manipulation of product color face inevitable limitations, from extrinsic flavors introduced by food coloring to the cost in development time and resources in order to produce different product variants. One solution lies in modern virtual reality technology, which has become increasingly accessible, sophisticated, and widespread over the past years. In the present study, we investigated whether making a (...) coffee look milkier in a VR environment can alter its perceived flavor and liking. Thirty-two United Kingdom consumers were given four samples of black cold brew coffee at 4 and 8% sucrose concentration. They wore VR headsets throughout the study and viewed the same coffee in a virtual setting. The color of the beverage was manipulated in VR, such that participants saw either a dark brown or light brown liquid as they sipped the coffee. A full factorial design was used so that each participant tasted each sweetness x color combination, Participants reported sweetness, creaminess, and liking for each sample. Results revealed that beverage color as viewed in VR significantly influenced perceived creaminess, with the light brown coffee rated to be creamier than dark brown coffee. However, beverage color did not influence perceived sweetness or liking. The present study supports the role of VR as a means of conducting food perception studies, either to gain a better understanding of multisensory integration, or, from an industry perspective, to enable rapid product testing when it may be time-intensive or costly to produce the same range of products in the real-world. Furthermore, it opens potential future opportunities for VR to promote healthy eating behavior by manipulating the visual appearance of foods. (shrink)

In order to maximize human performance, defence forces continue to explore, develop, and apply human performance enhancement (HPE) methods, ranging from pharmaceuticals to (bio)technological enhancement. This raises ethical, legal, and societal concerns and requires organizing a careful reflection and deliberation process, with relevant stakeholders. We discuss a range of ethical, legal, and societal aspects (ELSA), which people involved in the development and deployment of HPE can use for such reflection and deliberation. A realistic military scenario with proposed HPE application can (...) serve as a starting point for such an iterative and participatory process. Stakeholders can discuss this application, modify its features, and design appropriate processes around it – for instance, procedures for informed consent. We propose that organizing aspects into these three categories – ethical, legal, and societal – can help involve appropriate interlocutors at different moments: legal aspects with people in strategy or management roles, from the start of a project; ethical aspects with people in operations and medical roles, during development; and societal aspects with people in communication and personnel roles, during deployment. Notably, we developed and discussed this framework and the three aspects in close collaboration with personnel from the military. (shrink)

Physiological studies show that the driving force for long distance transport and the control of nutrient movement in plants resides largely in the regulated, membrane transport of a few carbohydrates, principally sucrose. The evidence is reviewed here and biochemical studies on sucrose carrier proteins are discussed.

This study investigates how ownership concentration in European multinational firms is associated with these firms’ corporate social responsibility (CSR). We employ factor analysis on responsibility data from EIRiS and use a regression analysis. Using firm-level data for almost 700 European firms, we find that shareholder concentration is significantly related to such policies. That is, more concentrated ownership goes hand in hand with poorer CSR policies. In our analysis, we control for size, leverage, profitability, industry, and country of origin. We use (...) several indicators for ownership concentration. We also find that with more concentrated ownership, CSR of the firm gets worse. We suggest that especially with large shareholders, CSR would need to be included in their performance assessment. (shrink)

Firms are increasingly personalising their offers and services, leading to an ever finer-grained segmentation of consumers online. Targeted online advertising and online price discrimination are salient examples of this development. While personalisation's overall effects on consumer welfare are expectably ambiguous, it can lead to concentration in the distribution of advertising and commercial offers. Constellations are possible in which a market is generally open to competition, but the targeted consumer is only made aware of one possible seller. For the consumer, such (...) a market could effectively resemble a monopoly. We call such extreme cases ‘targeting pockets’. Competition-law metrics such as the Herfindahl–Hirschman Index and traditional means of public oversight of adverts would not detect this concentration. We, therefore, suggest a novel metric, the Concentration-after-Personalisation Index (CAPI). The CAPI treats every consumer as a separate ‘market’, computes a measure of concentration for personalised adverts and offers for each individual consumer separately, and then averages the result to measure the exposure experienced by an average consumer. We demonstrate how the CAPI can serve as a monitoring tool for regulators and auditors and thus help to enforce existing consumer law as well as proposed new regulations such as the European Union's Digital Services Act and its Artificial Intelligence Act. We further show how adding noise via randomly distributed non-personalised adverts can dilute the potential harm of overly concentrated personalisation. We demonstrate how the CAPI can identify the optimal degree of added noise, balancing the protection of consumer choice with the economic interests of advertisers. (shrink)

Ontologies aim to represent what is general, by means of universal statements. In contrast, dispositional predications capture knowledge about what is likely to happen if a certain set of circumstances obtain, which is crucial in investigative research such as in drug discovery and systems biology, where entities which are constitutionally dissimilar can nevertheless have similar behavior in a biological context. While such dispositional properties are increasingly included in biomedical ontologies, the circumstances under which the dispositions are realized are seldom explicitly (...) modeled, and doing so is problematic due to the necessary restriction to binary relations in OWL ontologies. In this paper we address this shortcoming, focusing on the bioactivity of small molecules at varying levels of concentration within a living organism as our problem domain, although our approach is generalizable to other problems. We discuss the ontological nature and representation of dispositions and their realization; consider the nature of concentrations and their representation; and finally we detail an approach to linking dispositions to the conditions for their realization which regards conditions as triggers for the process in which the disposition is realized.

When examining the current form that modern society has acquired, it is hard to overlook the emergence of a systemic dimension that has become far removed from its social-symbolic roots. This systemic dimension is the result of a process of functional differentiation and simultaneous growth that has led to the gradual formation of social systems that, alongside their coordinating effect, give rise to multiple conflicts or crises. But how are the crises of modern societies to be understood in light of (...) this logic of functional differentiation and internal growth? The purpose of this article is to postulate one particular form of crisis, which will be understood as the result of a consubstantial tendency towards systemic growth. The trend takes the form of a concentration of the performances of social systems that recreates modern schemes of stratification, homogenizes the diversity of options and selections of these systems and, by becoming caught up in thoughtless patterns of growth, produces critical scenarios.

This study uses insights from the political perspective on corporate governance to investigate the influence of geographic concentration of institutional blockholders on workplace safety violations. When institutional investors who have a blockholding stake (i.e., institutional blockholders) are geographically concentrated, corporate managers are more likely to pursue efficiency at the expense of employee interests because these blockholders may find it easier to coordinate their actions, strengthening their power over corporate managers and ultimately giving rise to more workplace safety violations. We also (...) contend that the influence of institutional blockholders’ geographic concentration on workplace safety violations hinges upon the ownership of employees, socially responsible investment funds, and the CEO. Findings from a longitudinal sample of 1316 U.S. firms support our arguments. This study contributes to a nascent stream of research examining the influence of capital market participants on workplace safety by highlighting the role of institutional blockholders’ geographic concentration as a new channel through which investors can shape employee outcomes.

Hierocles, a Stoic of the second century CE, famously deployed an image of the ‘concentric circles’ that surround each of us. The image should not be read as advocating absolute impartiality (in the style of classical utilitarianism) or as illustrating the Stoic theory of oikeiōsis. Instead, it is designed to illustrate how it is ‘appropriate to act’ in certain cases. Like other Stoics, Hierocles bases his investigation of appropriate acts on what is ‘in accordance with nature’. According to his view, (...) each of us has a duty of mutual aid towards every other human being—but a weightier duty towards those who are socially closer than those who are more distant. The fundamental principle is that each of us has the duty of being an ‘ally’ of every other human being in serving the natural purposes of all the circles to which we and that other human being both belong.

ArgumentThis paper argues that the economics discipline is highly concentrated, which may inhibit scientific innovation and change in the future. The argument is based on an empirical investigation of six dimensions of concentration in economics between 1956 and 2016 using a large-scale data set. The results show that North America accounts for nearly half of all articles and three quarters of all citations. Twenty institutions reap a share of 42 percent of citations, five journals a share of 28.5 percent, and (...) 100 authors a share of 15.5 percent. A total of 2.8 percent of citations may be attributed to heterodox schools of thought. Also top articles are concentrated along these dimensions. Overall, concentration has strongly increased over the last six decades. (shrink)

Written in a simple and easily understandable style, Concentration is a classic among books on the art of meditation. Published, as it was, before our fascination with things New Agey, it dispels many of the myths and misconceptions that have arisen and been promoted out of that movement. And for this reason alone, for the preservation of the truth, it is worth its weight in gold. First and foremost among the myths it dispels is the idea that developing concentration is (...) really of no consequence in the practical application of the art of meditation, as some so-called New Age gurus would have people believe. This is like saying that for an automobile to function properly it doesnt need gasoline! Without the ability to concentrate, our efforts at meditation will result only in going nowhere, in spinning our wheels in an unending rut. (shrink)

The Buddhist jhanas--successive states of deep focus or meditative absorbtion--demystified. A very practical guidebook for meditators for navigating their way through these states of bliss and concentration. One of the elements of the Eightfold Path the Buddha taught is Right Concentration: the one-pointedness of mind that, together with ethics, livelihood, meditation, and so forth, leads to the ultimate freedom from suffering. The Jhanas are the method the Buddha himself taught for achieving Right Concentration. They are a series of eight successive (...) states, beginning with bliss and moving on toward radically nonconceptual states. The fact that they can usually be achieved only during prolonged meditation retreat tends to keep them shrouded in mystery. Leigh Brasington is here to unshroud them. He takes away the mystique and gives instructions for them in plain, accessible language, noting the various pitfalls to avoid along the way, and then providing a wealth of material on the theory of jhana practice--all geared toward the practitioner rather than the scholar.

This essay is concerned with concentrations of entities, which play an important—albeit often overlooked—role in scientific explanation. First, I discuss an example from molecular biology to show that concentrations can play an irreducible causal role. Second, I provide a preliminary philosophical analysis of this causal role, suggesting some implications for extant theories of causation. I conclude by introducing the concept of causation by concentration, a form of statistical causation whose widespread presence throughout the sciences has been unduly neglected (...) and which deserves to be studied in more depth. 1 Introduction2 Solving Lillie's Paradox: Lysogenic Induction in Phage λ3 Repressor Concentration and the Tuning of the Switch4 Concentration and Causality5 Preemption in Concentrations: Analysis and Implications6 Causation by Concentration: General Definition, Refinements, and Further Applications.

This essay is part of a special issue celebrating 50 years of Political Theory. The ambition of the editors was to mark this half century not with a retrospective but with a confabulation of futures. Contributors were asked: What will political theory look and sound like in the next century and beyond? What claims might political theorists or their descendants be making in ten, twenty-five, fifty, a hundred years’ time? How might they vindicate those claims in their future contexts? How (...) will the consistent concerns of political theorists evolve into the questions critical for people decades or centuries from now? What new problems will engage the political theorists (or their rough equivalents) of the future? What forms might those take? What follows is one of the many confabulations published in response to these queries. (shrink)
