Controversies in food and agriculture abound, with many portrayed as conflicts between polarized viewpoints. Framing such controversies as dichotomies, however, can at times obscure what might be a plurality of views and potential common ground on the subject. We used Q methodology to explore stakeholders’ views about pesticide safety, agricultural worker exposure, and human health concerns in the tree fruit industry of central Washington State. Using a purposive sample of English and Spanish-speaking agricultural workers, industry representatives, state agencies, educators, and (...) advocates, participants sorted 45 statements on pesticide use and perceived human safety risks in the tree fruit industry in 2011. We used PQMethod 2.33 statistical software program to identify viewpoints, based on differences between how participants sorted the statements. The results revealed three distinct viewpoints among 38 sorters that explained 52 percent of the variance. The viewpoints included the: skeptics who expressed concern over the environmental and human health impacts of pesticide use; acceptors who acknowledged inherent risks for using pesticides but saw the risks as known, small and manageable; and incrementalists who prioritized opportunities to introduce human capital and technological improvements to increase agricultural worker safety. We then brought representatives with these different viewpoints together to analyze the results of the Q study, and to brainstorm mutually acceptable improvements to health and safety in tree fruit orchards. In describing and analyzing this case study, we argue that Q methodology can serve as one potentially effective tool for collaborative work, in this case facilitating a process of orchard safety improvements despite perceived stakeholder polarization.

Graphical models are a powerful tool for causal model specification. Besides allowing for a hierarchical representation of variable interactions, they do not require any a priori specification of the functional dependence between variables. The construction of such graphs hence often relies on the mere testing of whether or not model variables are marginally or conditionally independent. The identification of causal relationships then solely requires some general assumptions on the relation between stochastic and causal independence, such as the Causal Markov Condition (...) and the Faithfulness Condition (Spirtes et al. 2000; Pearl 2000). However, a procedure would require further assumptions to hold. Namely those the independence tests themselves are based on. In continuous settings, Spirtes et al. (2000) suggest causal inference based on a very restrictive formulation of independence, that is, vanishing partial correlations. Such a measure does, however, limit the applicability of causal inference to linear systems. This constitutes a serious drawback especially for the social sciences where an a priori specification of the functional form proves difficult or at odds with linearity. In short: graphical models theoretically reduce specification uncertainty regarding functional dependence, but their implementation in practice deprives them of this virtue. In this paper we investigate how causal structures in continuous settings can be identified when both functional forms and probability distributions of the variables remain unspecified. We focus on tests exploiting the fact that if X and Y are conditionally independent given a set of variables Z, the two conditional densities f (X|Y, Z) and f (X|Z) must coincide. We start by estimating the conditional densities f(X|Y, Z) and f(X|Z) via nonparametric techniques (kernel methods). We proceed by testing if some metric expressing the distance between these very conditional densities is sufficiently close to zero. Out of several metrics available in the literature to express such distance we choose two, the Euclidean, and the Hellinger distance. We investigate in a Monte Carlo study how different tests involving either measure are able to detect statistical independence, conditioned on a small set of variables. One limitation may result from nonparametric density estimation being subject to the curse of dimensionality. As the number of variables increases, the estimated empirical density converges at a slower rate to its population value. To compensate this drawback we use a local bootstrap procedure which consists of resampling the data for each test. While local bootstrap strongly increases the computational time of the test, it succeeds in counterbalancing the curse of dimensionality. (shrink)

Aus einer philosophisch-phanomenologischen und literaturwissenschaftlichen Perspektive heraus gewinnt Nadine Benz nahere Erkenntnisse uber das temporale Phanomen des Wartens. Zunachst wird die historische Entwicklung der Zeitvorstellung aus philosophisch-phanomenologischer Sicht thematisiert, spezifisch im Hinblick auf die Fragen nach Messbarkeit, Vermitteltheit und nach objektiven und subjektiven Komponenten von Zeiterfahrung in ihrer Aporetik. Im Anschluss wird vom Konzept der Lebenswelt zur Literatur ubergeleitet: Die vorliegende Studie bindet die Aporien der Zeit zunachst theoretisch in eine Narratologie von Zeiterfahrung ein, die vor allem den Faktor (...) des Fiktiven produktiv berucksichtigt. Schliesslich werden die gewonnenen Erkenntnisse und Instrumente fur eine Analyse von Erzahltexten des 20. und 21. Jahrhunderts fruchtbar gemacht. Hier erlangen die literarischen Konfigurationen von Wartezeit als Semantiken des Wartens fur die Subjekte der fiktiven Zeiterfahrung einen konstitutiven Status. (shrink)

The notion of computation has changed the world more than any previous expressions of knowledge. However, as know-how in its particular algorithmic embodiment, computation is closed to meaning. Therefore, computer-based data processing can only mimic life’s creative aspects, without being creative itself. AI’s current record of accomplishments shows that it automates tasks associated with intelligence, without being intelligent itself. Mistaking the abstract for the concrete has led to the religion of “everything is an output of computation”—even the humankind that conceived (...) the computer. The hypostatized role of computers explains the increased dependence on them. The convergence machine called deep learning is only the most recent form through which the deterministic theology of the machine claims more than what it actually is: extremely effective data processing. A proper understanding of complexity, as well as the need to distinguish between the reactive nature of the artificial and the anticipatory nature of the living are suggested as practical responses to the challenges posed by machine theology.

The artistic work of photographer Gudio Baselgia focuses on landscapes formed by nature s forces and, more recently, on the sky with the stellar and solar movements and phenomena as we see them from earth. Celestial mechanics have fascinated mankind in all known cultures, the Babylonians and ancient Egyptians as well as the Greek and Celts, the Maya, or the ancient Indians and Chinese. Until the present day we look at the sky and keep being amazed, and try to read (...) what it tells us. Many artists throughout history have been captivated by the spectacle we observe above us day and night. The modern term astrodynamics describes all movements of celestial bodies, in particular the solar system including the moon and other satellites, asteroids and comets, but also movements of stars within a stellar system or galaxy, or of galaxies towards each other. They are well understood today and depicted in coordinate systems and elaborate visualizations. Guido Baselgia s artistic project on astrodynamics and celestial phenomena has no scientific or didactic ambition. His analogue camera is used as a recorder inscribing the movement of stars on the light-sensitive surface of photographic paper. Thus Baselgia s images make traceable the trajectory of celestial bodies invisible to the human eye and show us astounding occurrences of light and shadow. Baselgia has been captivated in particular also by the phenomenon of the umbra, planet earth s shadow thrown into space. It becomes visible occasionally on a clear evening at sunset when a slight mist lies at the horizon: looking in opposite direction to the sun, a dark and sharply marked band of shadow can be seen rising while sun sets behind the observer. But also by recording sunrise and sunset at the polar circle or the tropic, Baselgia visualizes the geometry of celestial mechanics and the concurrence of forces, as well as the miracle of light as such that leaves us awestruck today as much as it did our ancestors. The new book "Guido Baselgia Light Fall" presents 80 outstanding black-and-white images from the artist s Light Fall project taken in Norway, the Tierra del Fuego archipelago in Argentina, in Ecuador, and the Swiss Alps. The brilliant tritone plates are complemented with essays by the German scholar Andrea Gnam and Swiss photography critic Nadine Olonetzky. ". (shrink)

The Druze movement originated at the beginning of the eleventh century and developed out of the Ismā'īlī faction of Shī'ī Islām. Founded by the Ismā'īlī Ḥamza ibn 'Alī, the Tawḥīd is a philosophical and spiritual path that incorporates the fundamentals of Islam, Christianity, and Judaism referred to in the Qur'ān, together with the ancient philosophies of Pythagoras, Plato, Aristotle, Plotinus, and others. It is a synthesis and a unification of the most contradictory thoughts, a synthesis that leads to the real (...)

The informed consent process presents challenges for psychological trauma research (e.g. Institutional Review Board [IRB] apprehension). While previous research documents researcher and IRB-member perspectives on these challenges, participant views remain absent. Thus, using a mixed-methods approach, we investigated participant views on consent guidelines in two convenience samples: crowdsourced (N = 268) and undergraduate (N = 265) participants. We also examined whether trauma-exposure influenced participant views. Overall, participants were satisfied with current guidelines, providing minor feedback and ethical reminders for researchers. Moreover, (...) participant views for consent were similar irrespective of trauma-exposure. Our study has implications for IRBs and psychological researchers. (shrink)

The current assumptions of knowledge acquisition brought about the crisis in the reproducibility of experiments. A complementary perspective should account for the specific causality characteristic of life by integrating past, present, and future. A “second Cartesian revolution,” informed by and in awareness of anticipatory processes, should result in scientific methods that transcend the theology of determinism and reductionism. In our days, science, itself an expression of anticipatory activity, makes possible alternative understandings of reality and its dynamics. For this purpose, the (...) study advances G-complexity for defining and comparing decidable and undecidable knowledge. AI and related computational expressions of knowledge could benefit from the awareness of what distinguishes the dynamics of life from any other expressions of change. (shrink)

Resident Evil is a multidimensional, multimedia universe. The essays written for this volume will focus on this particular zombie manifestation and its significance in popular culture, cover a wide range, and discuss numerous issues. Among them are game theory, the idea of silence as well as memory, the connection to iconic stories, posthumanism and much more.

This book contains an introduction to mathematical proofs, including fundamental material on logic, proof methods, set theory, number theory, relations, functions, cardinality, and the real number system. The book is divided into approximately fifty brief lectures. Each lecture corresponds rather closely to a single class meeting.

This article re-examines the profession of the late antique mechanikos, who is identified as a practising architect with a sound liberal arts education as well as practical training. Despite the practical orientation of his profession, the mechanikos was of high social standing. This was possible because the practical utility of a vocation was increasingly acknowledged favourably in late antiquity and is reflected in early Byzantine portrayals of patrons, who allegedly invested hard labour in prestigious building campaigns and posed as the (...) supreme architects.

ABSTRACT Despite Institutional Review Board concerns about psychological harm arising from research participation, evidence from trauma-questionnaire research suggests that participation is typically well-tolerated by participants. Yet, it is unclear how participant experiences of in-lab trauma simulations align with IRB ethical guidelines. Thus, we compared reactions to a trauma film paradigm with reactions to a positive film task or cognitive tasks. Overall, relative to other conditions, the trauma film was well-tolerated by participants: they generally reported low-to-moderate negative emotions, moderate benefits, and (...) that participation was not worse than everyday stressors. Our results have implications for the research community in designing trauma-based research. (shrink)

Older adults often have long-term relationships, and many of their goals are intertwined with their respective partners. Joint goals can help or hinder goal progress. Little is known about how accurately older adults assess if a goal is joint, the role of over-reporting in these perceptions, and how joint goals and over-reporting may relate to older partners' relationship satisfaction and physical health. Two-hundred-thirty-six older adults from 118 couples listed their three most important goals and whether they thought of them as (...) goals they had in common with and wanted to achieve together with their partner. Two independent raters classified goals as “joint” if both partners independently listed open-ended goals of the same content. Goal progress and relationship satisfaction were assessed 1 week later. Allostatic load was calculated using nine different biomarkers. Results show that 85% self-reported at least one goal as joint. Over-reporting– the perception that a goal was joint when in fact it was not mentioned among the three most salient goals of the spouse – occurred in one-third of all goals. Multilevel models indicate that the number of externally-rated joint goals was related to greater goal progress and lower allostatic load, but only for adults with little over-reporting. More joint goals and higher over-reporting were each linked with more relationship satisfaction. In conclusion, joint goals are associated with goal progress, relationship satisfaction, and health, but the association is dependent on the domain of functioning. (shrink)

This paper demonstrates how argumentation schemes can be used in decision support systems that help clinicians in making treatment decisions. The work builds on the use of computational argumentation, a rigorous approach to reasoning with complex data that places strong emphasis on being able to justify and explain the decisions that are recommended. The main contribution of the paper is to present a novel set of specialised argumentation schemes that can be used in the context of a clinical decision support (...) system to assist in reasoning about what treatments to offer. These schemes provide a mechanism for capturing clinical reasoning in such a way that it can be handled by the formal reasoning mechanisms of formal argumentation. The paper describes how the integration between argumentation schemes and formal argumentation may be carried out, sketches how this is achieved by an implementation that we have created and illustrates the overall process on a small set of case studies.
