Going belowground: burying anthropomorphic biases on gustation and olfaction
Get PDFChemical signaling underpins behavioral interactions among organisms in the soil. Understanding chemical communication in the soil requires a paradigm shift in methodology and perspectives compared to aboveground ecosystems because olfaction and gustation, accepted modalities of chemosensation aboveground, may not accurately represent chemical communication in the soil. To fully understand chemical communication in the soil, it is essential to consider how soil properties, such as moisture, pH, and adsorption, affect the transport and perception of semiochemicals. De-anthropomorphizing the study of chemosensation can avoid potential biases, particularly in soil systems, where distinctions between olfaction and gustation are confounded by the heterogeneity of the soil environment and its effects on the mobility of chemical signals. In this perspective, we first explore how soil heterogeneity confounds the dichotomy between olfaction and gustation with hypothetical but ecologically relevant examples. Then we examine how anthropomorphic biases in aboveground chemical ecology have influenced soil chemical ecology. Our examples and discussion are prepared primarily in reference to soil arthropods. We conclude by discussing seven future research directions and outstanding questions. The soil is a premier example of a system where investigators should avoid anthropomorphisms when studying behavioral and chemical ecology. Research in soil chemical ecology should further efforts towards developing a unified view of chemosensation that could apply to all environments where chemical communication occurs

Quantifying the Effect of Water Temperature, Soap Volume, Lather Time, and Antimicrobial Soap as a Factor in the Removal of Escherichia coli ATCC 11229 from Hands
No full textThe handwashing literature, while extensive, often contains conflicting data and key variables are understudied or not studied at all. Some handwashing recommendations are made without scientific support, and there is limited agreement between recommendations. The influence of key variables including soap volume, lather time, water temperature, and product formulation on hand wash efficacy was investigated. Baseline conditions were 1 mL of a bland (nonantimicrobial) soap, a 5 s lather time, and 38 °C (100 °F) water temperature. A nonpathogenic strain of Escherichia coli ATCC 11229 served as the challenge microorganism. Twenty volunteers (10 men, 10 women) participated in the study and each test condition had 20 replicates. An antimicrobial soap formulation (1% chloroxylenol, or PCMX) was not significantly different from the bland soap at removing E. coli under a variety of test conditions. Overall, the antimicrobial soap used in this study had a mean 1.94 log CFU reduction (range 1.83 to 2.10 mean log reduction), and bland soap had a mean 2.22 log CFU reduction (range 1.91 to 2.54 mean log CFU reduction). Overall, lather time did significantly influence efficacy in one scenario, in which a 0.5 greater log reduction was observed for a 20 s with bland soap compared to the baseline wash (P=0.020). Water temperature as high as 38°C (100°F) vs. a low of 15°C (60°F) did not have a significant effect on the reduction of bacteria during hand washing, however this resulted in an energy usage difference between the temperatures. No significant differences were observed between mean log reductions of men and women (men= 2.08 mean log reduction, women=2.08 mean log reduction, P=0.988). A large part of the variability in the data observed was between the volunteers. Understanding what behaviors and human factors influence hand washes the most may help future studies find which techniques can optimize the effectiveness of a hand wash.Peer reviewe
A commentary with introduction on the Florida of Apuleius.
No full textPhDThe most recent, and in many ways the best, text of the Florida
of Apuleius is that of P. Vallette in the Budé series (Paris, 1924).
I have, however, used the Teubner text by R. Helm (Leipzig, 1910, reprinted
with addenda 195 and 1959) as the basis for this Commentary, mainly
because of the usefulness of Helm's critical apparatus, which is
considerably fuller than Vallette's. I have discussed variant readings
where the sense appears to be affected, but I have made no independent
study of the MSS. This Commentary makes no claim to be a critical edition.
I have been more concerned with interpretation and elucidation than
with matters of style, though in an author like Apuleius the two aspects
cannot always be separated. A commentary is not, however, the most
convenient medium for a stylistic study. I have commented mainly on
subject matter, on the language (including points of grammar), and on
anything of general or special interest that appeared to throw light on
the meaning and intention of the author.
In the Introduction I have considered the question of the
composition of the Florida. My conclusion is that the passages, as we
now have them, are excerpts from an earlier collection made by Apuleius
himself, and that the division into four books goes back to this original
collection. I have also tried to show that, even in its present mutilated
state, the Florida gives a unique insight into Apulelus' manner as a
public speaker and his relations with his Carthaginian audience.
For convenience, I have inserted the Bibliography at the beginning
of the work, so that the reader may more easily refer back to the list of
older editions, which are discussed in the first section of the

The logic of the violence in the civil war: the armed conflict in Colombia
Get PDFThis paper proposes a reading of the armed conflict from an evolutionary design that takes into account the Logic of Violence in the Civil War. Their aim is to assess the dynamics of conflict and changes from its author's scientific output. A context of conflicts that includes new expressions of violence and the relative failure of the paramilitary reintegration involves using new analytical models (argumentation, game theory and inconsistent information). The recent evolution of emerging gangs and their expansion into areas that were paramilitary camps requires monitoring not only of the government and the authorities, but those investigating the conflict in the present tense. The author provides heuristic research support from Schelling’s theory of strategy, Nozick’s agencies and the protection, and Gambetta’s recent contributions to the relationship between organized crime and drug cartels.Civil_war, Colombia, armed conflict, strategic_theory, Gambetta, Nozick, Schelling
Glosa do wyroku Trybunału Sprawiedliwości z dnia 7 grudnia 2017 roku w sprawie C-329/16
Get PDFThe article discusses the problem with classifying medical software as a medical system. The author supports the line of Court of Justice of the European Union — in case C-329/16 of December 7, 2017 — which states that the medical software could be a medical system, regardless of whether it affects the human body, but it would have to be more than just a data collector. The medical software must serve a medical purpose and in a medical context only.Tekst odnosi się do problemu klasyfikacji oprogramowania medycznego jako wyrobu medycznego. Autor popiera stanowisko Trybunału Sprawiedliwości Unii Europejskiej — wyrażone w sprawie C-329/16 z dnia 7 grudnia 2017 roku — które odnosi się do tego, że oprogramowanie medyczne może stanowić w świetle prawa wyrób medyczny bez względu na to, czy bezpośrednio oddziałuje na ludzkie ciało. Co ważne, oprogramowanie to musi być czymś więcej niż systemem wyłącznie zbierającym dane pacjentów. Takie oprogramowanie medyczne wymaga specjalistycznego celu oraz umiejscowienia w określonym kontekście medycznym
Polyphony and the anxiety of influence in the fiction of Henry James
Get PDFJames's fiction, especially in the Middle Phase, centres
on the figure of the artist and is characterized by, the two
interrelated aspects which previous criticism has largely
overlooked: the Bakhtinian 'polyphonic' -creation of
'author-thinkers'; and the conflict between ephebes and
precursors, for which Harold-Bloom's concept of 'the-anxiety of
influence' is the most illuminating model. Polyphony is the
narrative mode, and influence is the intra-artistic, theme.
These, as the Introduction to the thesis makes clear, are
rehearsed in James's inaugural novel, Roderick Hudson. Rowland
Mallet is an author-thinker, and his failure is caused by
authorial limitations. His monologism -is impaired by his
mistaking empathy for the authorial sympathy. Likewise,
Hudson's failure does not arise from a mercurial temperament,
but from a polyphonic shortcoming: not possessing the power of
fiction to contain the fiction of power in, his mentor. And the
relationships among the three artists - Gloriani, Hudson and
Singleton - perfectly exemplify the Bloomian-theme. It is these
two concepts, polyphony and influence, which are the major
preoccupation in the Middle Phase; as, the works chosen
demonstrate. These are a novella, a novel, and a number of
short stories all of which have been unjustifiably neglected.
Chapter One, on The Aspern Papers, argues that Tina Bordereau,
far from being, the artless victim seen by many critics,
actually challenges and defeats the narrator by the very form
of her narrative. Her 'realist' discourse undermines his
language of 'romance', and shows up its internal unstability.
Chapter Two is an extensive study of the critical reception of
The Tragic Muse. The most common areas of critical attention
have been its contemporary topicality, its relation to previous
novels on similar themes, and the possible genealogy of Gabriel
Nash. Those have all missed the core of the work. - Chapter Three
demonstrates how polyphony and the anxiety of influence make
the novel what it really is. Influence arises from the
juxtaposition of, and the wrestling between, artistic ephebes
and their precursors (Nick and Nash,, Miriam and Madame Carre).
The dialogic quality defined by Bakhtin is crucial to the
proper, and even-handed, characterization of all, the conflicts
in the novel. And since most of James's tales in the eighties
and nineties -are about 'masters - and acolytes, the anxiety of
influence remains central. Chapter Four is a study of 'The
Author of Beltraffiol' and 'The Lesson of the Master'. Again the
characters' manipulations are a crucial focus in a way that
G6rard Genette's terminology helps to illuminate. The fact that
the ephebe is the author-thinker emphasizes the inextricability
of the Bakhtinian and the Bloomian in James. Just as
polyphony offers a different focus for explicating the poetics
of James's fiction; so the ephebal conflict provides the basis
for a fresh perception of James's own artistic struggle
The life and works of James Miller, 1704-1744, with particular reference to the satiric content of his poetry and plays.
No full textPhDJames Miller was born the son of a Dorset rector in 1704. He
was himself ordained, but acquired no benefice until just before his
early death, probably because of a scathing portrayal of the Bishop
of London in one of his verse satires. At Oxford he wrote a vivacious
comedy of humours, set in the University. Its production in 1730
began his dramatic career, at a time when the number of London
theatres had just doubled, and new dramatic forms were being invented.
In 1731 his poem Harlequin-Horace, a witty inversion of
the Ars Poetica, attacked pantomime and opera, but also painted a
lively portrait of the entire theatrical world, in the tradition of
the Dunciad.
After collaborating in a translation of Moliere's works Miller
wrote two plays based on this author. Of all his dramatic works
these were the most successful with his contemporaries, and were
followed by a modernisation of Much Ado, and a ballad-opera adapted
from an afterpiece by Jean-Baptiste Rousseau, and rendered highly
topical. Miller made similar use of a recent French comedy showing
a Red Indian's reactions to civilisation, a satiric "fable" by Walsh
and Voltaire's Mahomet. A large quantity of original material was
incorporated into most of these, and this is generally satirical in
nature. The Indian is made to voice almost egalitarian sentiments.
An afterpiece, "The Camp Visitants", satirised military inaction
in the war, and was apparently banned. The manuscripts of the six
plays produced after the Licensing Act bear the examiner's deletions,
and illustrate the nature of the censorship at this time.
Miller's greatest strength is probably his flexible, vigorously
colloquial dialogue. His political satire is mostly contained in
the poetry, which attacks Walpole's administration with increasing
vehemence through the seventeen-thirties, until its fall. In 1740
two poems that used Pope in symbolic contrast to Walpole caused a
sensation. In both poetry and plays Miller is also a social satirist,
who lays unusually strong emphasis on false taste and the deterioration
of culture
