Sequence effects in the categorization of tones varying in frequency

In contrast to exemplar and decision-bound categorization models, the memory and contrast models described here do not assume that long-term representations of stimulus magnitudes are available. Instead, stimuli are assumed to be categorized using only their differences from a few recent stimuli. To test this alternative, the authors examined sequential effects in a binary categorization of 10 tones varying in frequency. Stimuli up to 2 trials back in the sequence had a significant effect on the response to the current stimulus. The effects of previous stimuli interacted with one another. A memory and contrast model, according to which only ordinal information about the differences between the current stimulus and recent preceding stimuli is used, best accounted for these dat

Phosphorus Budget of the Hyrum Reservoir - Little Bear River System

Phosphorus concentrations in the water of the Hyrum Reservoir - Little Dear River Watershed were determined by collecting 12 samples every two weeks over a seven month period and analyzing them for dissolved orthophosphate, total dissolved phosphorus, and total unfiltered phosphorus. The concentrations obtained were used in conjunction with a water budget to determine a phosphorus budget. Apparent major inputs of phosphorus to the reservoir included a trout farm and runoff from agricultural land in the watershed. Statistical analyses of the data were made to determine what effect precipitation, streamflow, and mileage downstream had on the concentrations of phosphorus in the watershed

The Russian Bride’s Attire: A Journey Through Art and Consciousness

This paper addresses the triad of, creativity, consciousness and culture. How the viewer “sees” the painting is influenced by consciousness and the surrounding culture – creativity is the creative process of the artist. Art is fluid in the sense that viewers see it differently at different times in their lives. The creative process experienced by the artist is the genesis of the painting. However, the art takes on a life of it’s own for every viewer. The definition of consciousness in this paper is based on the awareness and environment of the viewer

Using the Responsible Suicide Reporting Model to increase adherence to global media reporting guidelines

Numerous guidelines on responsible reporting of suicide are available to journalists globally, offering advice on best practice regarding approaches and suitability of content. Whilst their advice is compelling and legitimate, their use is uneven at best. With a suicide death every 40 seconds worldwide, it is imperative journalists understand and recognise the best ethical practices in order to report suicide responsibly. To address these shortcomings, the authors present a model for responsible suicide reporting (RSR) that is grounded in news-work and embeds media reporting guidelines within journalistic storytelling practices. The RSR model consists of a typology of suicide narratives and ‘othering’, ethical rules and a standard of moderation. Methodologically, these typologies emerged from analysis of 159 suicide news stories published in 2018–19, with particular focus on adherence and non-adherence to global media reporting guidelines. We posit through the process of producing stories using the RSR model, journalists should interact more effectively with critical risk factors for example, stigmatisation, copycat effects, harmful speculation, highlighted by media reporting guidelines

Representation of Lexical Form: Evidence From Studies of Sublexical Ambiguity

The authors examined the role of intermediate, sublexical representations in spoken word perception. In particular, they tested whether flaps, which are neutralized allophones of intervocalic /t/s and /d/s, map onto their underlying phonemic counterparts. In 2 shadowing tasks, the authors found that flaps primed their carefully articulated counterparts, and vice versa. Because none of the flapped stimuli were lexically ambiguous (e.g., between rater and raider), these results provide evidence that such priming is sublexically mediated. Therefore, the current study provides further insights into when underlying form-based representations are activated during spoken word processing. In particular, the authors argue that phonological ambiguity, inherent in their flapped stimuli, is one of the conditions leading to the activation of underlying representations

Measurement Invariance, Entropy, and Probability

We show that the natural scaling of measurement for a particular problem defines the most likely probability distribution of observations taken from that measurement scale. Our approach extends the method of maximum entropy to use measurement scale as a type of information constraint. We argue that a very common measurement scale is linear at small magnitudes grading into logarithmic at large magnitudes, leading to observations that often follow Student's probability distribution which has a Gaussian shape for small fluctuations from the mean and a power law shape for large fluctuations from the mean. An inverse scaling often arises in which measures naturally grade from logarithmic to linear as one moves from small to large magnitudes, leading to observations that often follow a gamma probability distribution. A gamma distribution has a power law shape for small magnitudes and an exponential shape for large magnitudes. The two measurement scales are natural inverses connected by the Laplace integral transform. This inversion connects the two major scaling patterns commonly found in nature. We also show that superstatistics is a special case of an integral transform, and thus can be understood as a particular way in which to change the scale of measurement. Incorporating information about measurement scale into maximum entropy provides a general approach to the relations between measurement, information and probability

Uncertainty behind the veil of ignorance

This paper argues that the decision problem in the original position should be characterized as a decision problem under uncertainty even when it is assumed that the denizens of the original position know that they have an equal chance of ending up in any given individual's place. It argues for this claim by arguing that (a) the continuity axiom of decision theory does not hold between all of the outcomes the denizens of the original position face and that (b) neither us nor the denizens of the original position can know the exact point where discontinuity sets in, because the language we employ in comparing different outcomes is ineradicably vague. It is also argued that the account underlying (b) can help proponents of superiority in value theory defend their view against arguments offered by Norcross and Griffin
