Soil type and soil management factors in hemp production
Hemp (Cannabis sativa) came into prominence as a strategic war crop shortly after United States\u27 imports of abaca and sisal were cut off from the Philippines and the Netherlands Indies. Production of hemp in the United States was expanded from about 3,000 acres annually during the period of 1939 to 1941 to 146,000\u27 acres in 1943.
Most of the additional acreage was planted in Minnesota, Iowa, Illinois and Indiana where farmers had little or no experience with hemp. Moreover, prior to the war period the minor economic importance of the crop, even in the old hemp-producing states of Kentucky and Wisconsin, had practically precluded the expenditure of much effort on experimental work to determine the response of the crop to different soil and management conditions. Thus, at the time the emergency arose, our knowledge of hemp growing was rather limited.
The experimental work reported in this bulletin was undertaken primarily to obtain information on the effect of soil types and soil management practices on the yield of hemp. Data are presented to show the effect of soil types, previous crops, time of plowing and method of planting on the yield of hemp, the effect of hemp on the yield of the following crops of hemp and corn, and the relative yields of hemp and corn
Visual Affect Around the World: A Large-scale Multilingual Visual Sentiment Ontology
Every culture and language is unique. Our work expressly focuses on the
uniqueness of culture and language in relation to human affect, specifically
sentiment and emotion semantics, and how they manifest in social multimedia. We
develop sets of sentiment- and emotion-polarized visual concepts by adapting
semantic structures called adjective-noun pairs, originally introduced by Borth
et al. (2013), but in a multilingual context. We propose a new
language-dependent method for automatic discovery of these adjective-noun
constructs. We show how this pipeline can be applied on a social multimedia
platform for the creation of a large-scale multilingual visual sentiment
concept ontology (MVSO). Unlike the flat structure in Borth et al. (2013), our
unified ontology is organized hierarchically by multilingual clusters of
visually detectable nouns and subclusters of emotionally biased versions of
these nouns. In addition, we present an image-based prediction task to show how
generalizable language-specific models are in a multilingual context. A new,
publicly available dataset of >15.6K sentiment-biased visual concepts across 12
languages with language-specific detector banks, >7.36M images and their
metadata is also released.Comment: 11 pages, to appear at ACM MM'1

Plasma sTNFR1 and IL8 for prognostic enrichment in sepsis trials: a prospective cohort study.
BackgroundEnrichment strategies improve therapeutic targeting and trial efficiency, but enrichment factors for sepsis trials are lacking. We determined whether concentrations of soluble tumor necrosis factor receptor-1 (sTNFR1), interleukin-8 (IL8), and angiopoietin-2 (Ang2) could identify sepsis patients at higher mortality risk and serve as prognostic enrichment factors.MethodsIn a multicenter prospective cohort study of 400 critically ill septic patients, we derived and validated thresholds for each marker and expressed prognostic enrichment using risk differences (RD) of 30-day mortality as predictive values. We then used decision curve analysis to simulate the prognostic enrichment of each marker and compare different prognostic enrichment strategies.Measurements and main resultsAn admission sTNFR1 concentration > 8861 pg/ml identified patients with increased mortality in both the derivation (RD 21.6%) and validation (RD 17.8%) populations. Among immunocompetent patients, an IL8 concentration > 94 pg/ml identified patients with increased mortality in both the derivation (RD 17.7%) and validation (RD 27.0%) populations. An Ang2 level > 9761 pg/ml identified patients at 21.3% and 12.3% increased risk of mortality in the derivation and validation populations, respectively. Using sTNFR1 or IL8 to select high-risk patients improved clinical trial power and efficiency compared to selecting patients with septic shock. Ang2 did not outperform septic shock as an enrichment factor.ConclusionsThresholds for sTNFR1 and IL8 consistently identified sepsis patients with higher mortality risk and may have utility for prognostic enrichment in sepsis trials
Empathy, engagement, entrainment: the interaction dynamics of aesthetic experience
A recent version of the view that aesthetic experience is based in empathy as inner
imitation explains aesthetic experience as the automatic simulation of actions,
emotions, and bodily sensations depicted in an artwork by motor neurons in the brain. Criticizing the simulation theory for committing to an erroneous concept of empathy and failing to distinguish regular from aesthetic experiences of art, I advance an alternative, dynamic approach and claim that aesthetic experience is enacted and skillful, based in the recognition of others’ experiences as distinct from one’s own. In combining insights from mainly psychology, phenomenology, and cognitive science, the dynamic approach aims to explain the emergence of aesthetic experience in terms of the reciprocal interaction between viewer and artwork. I argue that aesthetic experience emerges by participatory sense-making and revolves around movement as a means for creating meaning. While entrainment merely plays a preparatory part in this, aesthetic engagement constitutes the phenomenological side of coupling to an artwork and provides the context for exploration, and eventually for moving, seeing, and feeling with art. I submit that aesthetic experience emerges from bodily and emotional engagement with works of art via the complementary processes of the perception–action and motion–emotion loops. The former involves the embodied
visual exploration of an artwork in physical space, and progressively structures and organizes visual experience by way of perceptual feedback from body movements made in response to the artwork. The latter concerns the movement qualities and shapes of implicit and explicit bodily responses to an artwork that cue emotion and thereby modulate over-all affect and attitude. The two processes cause the viewer to bodily and emotionally move with and be moved by individual works of art, and consequently to recognize another psychological orientation than her own, which explains how art can cause feelings of insight or awe and disclose aspects of life that are unfamiliar or novel to the viewer
The Observing facet of trait mindfulness predicts frequency of aesthetic experiences evoked by the arts
Mindfulness can foster an enhanced sensitivity to internal and external impressions, which could result in heightened subjective responses to works of art. So far though, very little is known about the connection between mindfulness and aesthetic responses to the arts, therefore the current study aimed to investigate whether there was an association between trait mindfulness and how often people report aesthetic experiences. We hypothesized that the Observing facet of mindfulness would positively predict the self-reported frequency of aesthetic experiences (aesthetic chills, feeling touched, and absorption). Participants in an online study (N = 207) completed the Five Factor Mindfulness Questionnaire, an Aesthetic Experiences scale in relation to the area of the arts a participant encountered most frequently in their daily life, and a measure of aesthetic expertise. Controlling for aesthetic expertise and sex, linear regression revealed that the Observing facet of mindfulness was positively associated with aesthetic experience, as predicted. Non-reactivity positively predicted aesthetic experience, while Non-judging was negatively associated with aesthetic experience. Potential explanations for the association between these three facets of trait mindfulness and aesthetic responses are discussed in relation to information-processing models of aesthetic experience. The findings provide preliminary support for the premise that levels of dispositional mindfulness are associated with the frequency of intense emotional responses to the arts, and recommendations for further research studies are outlined
Biophilic architecture: a review of the rationale and outcomes
Contemporary cities have high stress levels, mental health issues, high crime levels and ill health, while the built environment shows increasing problems with urban heat island effects and air and water pollution. Emerging from these concerns is a new set of design principles and practices where nature needs to play a bigger part called “biophilic architecture”. This design approach asserts that humans have an innate connection with nature that can assist to make buildings and cities more effective human abodes. This paper examines the evidence for this innate human psychological and physiological link to nature and then assesses the emerging research supporting the multiple social, environmental and economic benefits of biophilic architecture
Wine and music (III): so what if music influences the taste of the wine?
A growing body of evidence, both anecdotal and scientifically rigorous, now points to the fact that what people taste when evaluating a wine, not to mention how much they enjoy the experience, can be influenced by the specifics of any music that happens to be playing at the same time. The question that we wish to address here is ‘So what?’ Why should anyone care that music (or, for that matter, specially composed soundscapes) exert(s) a crossmodal influence over the wine-tasting experience? ‘Why not just drink great wine and forget about the music?’ a sceptic might ask. Here, we outline a number of the uses that such research findings have been put to in the marketplace, in experiential events, in artistic performances, and in terms of furthering our theoretical understanding of those factors that influence the tasting experience. We also highlight how the latest in technology (think sensory apps and hyperdirectional loudspeakers, not to mention digitally augmented glassware) augurs well for those wanting to deliver the most stimulating, the most memorable, and certainly the most multisensory of tasting experiences in the years to come. Demonstrations of sound’s influence on wine perception will most likely be applicable to a variety of other drinks and foods too. Ultimately, the argument is forwarded that there are many reasons, both theoretical and applied, as to why we should all care about the fact that what we listen to can change the sensory-discriminative, the descriptive, and the hedonic attributes of what we taste
The default-mode network represents aesthetic appeal that generalizes across visual domains
Visual aesthetic evaluations, which impact decision-making and well-being, recruit the ventral visual pathway, subcortical reward circuitry, and parts of the medial prefrontal cortex overlapping with the default-mode network (DMN). However, it is unknown whether these networks represent aesthetic appeal in a domain-general fashion, independent of domain-specific representations of stimulus content (artworks versus architecture or natural landscapes). Using a classification approach, we tested whether the DMN or ventral occipitotemporal cortex (VOT) contains a domain-general representation of aesthetic appeal. Classifiers were trained on multivoxel functional MRI response patterns collected while observers made aesthetic judgments about images from one aesthetic domain. Classifier performance (high vs. low aesthetic appeal) was then tested on response patterns from held-out trials from the same domain to derive a measure of domain-specific coding, or from a different domain to derive a measure of domain-general coding. Activity patterns in category-selective VOT contained a degree of domain-specific information about aesthetic appeal, but did not generalize across domains. Activity patterns from the DMN, however, were predictive of aesthetic appeal across domains. Importantly, the ability to predict aesthetic appeal varied systematically; predictions were better for observers who gave more extreme ratings to images subsequently labeled as “high” or “low.” These findings support a model of aesthetic appreciation whereby domain-specific representations of the content of visual experiences in VOT feed in to a “core” domain-general representation of visual aesthetic appeal in the DMN. Whole-brain “searchlight” analyses identified additional prefrontal regions containing information relevant for appreciation of cultural artifacts (artwork and architecture) but not landscapes
Rapid timing of musical aesthetic judgments
In recent years, psychological models of perception have undergone reevaluation due to a broadening of focus toward understanding not only how observers perceive stimuli but also how they subjectively evaluate stimuli. Here, we investigated the time course of such aesthetic evaluations using a gating paradigm. In a series of experiments, participants heard excerpts of classical, jazz, and electronica music. Excerpts were of different durations (250 ms, 500 ms, 750 ms, 1,000 ms, 2,000 ms, 10,000 ms) or note values (eighth note, quarter note, half note, dotted-half note, whole note, and entire 10,000 ms excerpt). After each excerpt, participants rated how much they liked the excerpt on a 9-point Likert scale. In Experiment 1, listeners made accurate aesthetic judgments within 750 ms for classical and jazz pieces, while electronic pieces were judged within 500 ms. When translated into note values (Experiment 2), electronica and jazz clips were judged more quickly than classical. In Experiment 3, we manipulated the familiarity of the musical excerpts. Unfamiliar clips were judged more quickly (500 ms) than familiar clips (750 ms), but there was overall higher accuracy for familiar pieces. Finally, we investigated listeners’ aesthetic judgments continuously over the time course of more naturalistic (60 s) excerpts: Within 3 s, listeners’ judgments differed between most- and least-liked pieces. We suggest that such rapid aesthetic judgments represent initial gut-level decisions that are made quickly, but that even these initial judgments are influenced by characteristics such as genre and familiarity
