The third benefit of no longer eating animals is a reduction in the prevalence of zoonotic diseases: diseases acquired from a nonhuman, vertebrate host. The majority of temperate diseases, almost all tropical diseases, and probably all newly emerging infectious diseases are zoonoses or they have zoonotic origins. A zoonotic pathogen can go through five stages, in which it transforms from one that afflicts only nonhuman species to one that is exclusively human. There are several factors that determine the likelihood of such a transformation. The most important of these, since it is most under our control, is the frequency of encounters between us and the animal reservoir. Eating animals and disturbing their environment are the two forms of human behavior most likely to increase frequency of encounters. Moreover, most disturbance of the environment is caused by expansion in animal agriculture. Eating animals, therefore, is the most important cause of zoonotic diseases.

Warning Indicators

Emerging and re-emerging infectious diseases and zoonoses indicate the importance of the One Health (OH) approach for early warning. At present, even when surveillance data are available, they are infrequently timeously shared between the health sectors. In the context of the MediLabSecure (MLS) Project, we investigated the collection of a set of surveillance indicators able to provide data for the implementation of integrated early warning systems in the 22 MLS countries of the Mediterranean, Black Sea and Sahel regions. We used an online questionnaire (covering vector, human, and animal sectors), focusing on seven relevant arboviruses, that was submitted to 110 officially appointed experts. Results showed that West Nile virus was perceived as the most relevant zoonotic pathogen, while Dengue virus was the most relevant non-zoonotic pathogen in the study area. Data collection of early warning indicators is in place at a different level for all the investigated pathogens and in almost all the MLS Countries. Further assessments on the reliability of the collection in place and on the feasibility of piloting an integrated early warning system for arbovirus could verify if integrated early warning really represents the Achilles’ heel of OH.

Cellulose sodium xanthates of degree of substitution (D.S.) 0.4 to 0.66 were methylated to xanthate S-methyl esters which were then acetylated completely, the final xanthate D.S. remaining close to the original value. Dexanthation with aqueous chlorine dioxide near pH 4.5 and −5° removed almost all of the S-methyl xanthate groups, but the loss of a few acetyl groups from, and the retention of 1 to 2% of sulphur in, the resulting cellulose acetate could not be avoided. The original xanthate groups were presumably represented in this acetate as unsubstituted hydroxyl groups, and these were located by standard methods involving tosylation–iodination, tritylation, and oxidations with lead tetraacetate. Xanthate groups appeared to occupy the third and sixth, but not the second, position in the cellulose, and 53 to 61% of the substituent was in the sixth or primary position; one sample of viscose was "ripened" before the cellulose sodium xanthate was isolated, and the value was 81%. The results were of a preliminary nature, because severe technical difficulties reduced their reliability.

World Health Organization (WHO) defines zoonotic diseases (zoonoses) as those diseases and infections which are naturally transmitted between vertebrate animals and humans. More than 250 zoonoses have been described, over 60% of pathogens that cause diseases in humans are zoonoses of animals, and 75% of emerging infectious diseases. Most pandemics are caused by zoonoses.

My research shows that he has conceived this notion more than a decade ago and it’s the result of his lifetime endeavor on comparative literature in East Asia. I have employed almost all his monographs to trace the gradual formation of his ideas with two books as the focus, <i>The Third Notion of Comparative Literature: the Possibility of Literary Archeology</i> and <i>The Image of Willow: The Material Exchange and the Ancient Chinese and Japanese Literature</i>. The former aims to construct the theory of literary archeology as a renovated subject matter and the latter is composed of the case studies on willow which provide abundant evidence to illustrate his point. </p>

Diatom Community Composition

Abstract. Diatoms, microscopic single-celled algae, are present in almost all habitats containing water (e.g. streams, lakes, soil and rocks). In the terrestrial environment, their diversified species distributions are mainly controlled by physiographical factors and anthropic disturbances which makes them useful tracers in catchment hydrology. In their use as a tracer, diatoms are generally sampled in streams by means of an automated sampling method; as a result, many samples must be collected to cover a whole storm run-off event. As diatom analysis is labour-intensive, a trade-off has to be made between the number of sites and the number of samples per site. In an attempt to reduce this sampling effort, we explored the potential for the Phillips sampler, a time-integrated mass-flux sampler, to provide a representative sample of the diatom assemblage of a whole storm run-off event. We addressed this by comparing the diatom community composition of the Phillips sampler to the composite community collected by automatic samplers for three events. Non-metric multidimensional scaling (NMDS) showed that, based on the species composition, (1) all three events could be separated from each other, (2) the Phillips sampler was able to sample representative communities for two events and (3) significantly different communities were only collected for the third event. These observations were generally confirmed by analysis of similarity (ANOSIM), permutational multivariate analysis of variance (PERMANOVA), and the comparison of species relative abundances and community-derived indices. However, sediment data from the third event, which was sampled with automatic samplers, showed a large amount of noise; therefore, we could not verify if the Phillips sampler sampled representative communities or not. Nevertheless, we believe that this sampler could not only be applied in hydrological tracing using terrestrial diatoms, but it might also be a useful tool in water quality assessment.

The chief way in which the Greeks united in the third century in order to be able to offer resistance to Macedon was by forming large federal states. The two greatest of these were based in Achaea and in Aetolia, but both quickly spread well beyond these ethnic borders. “Aetolia” came to mean almost all of central Greece, and “Achaea” much of the Peloponnese. I discuss the differences between confederacies and the most familiar form of ancient Greek polity, the polis, and show how confederacies gained their strengths, before focusing on the structures set up by the Aetolians and Achaeans. By the time Antigonus came to the Macedonian throne, the Achaeans were on the rise, but the Aetolians were already a powerful threat. They had spearheaded the Greek repulsion of the Celts from central Greece, thus preserving Delphi, the most important of the Greeks’ common religious centers, and they used this as a springboard for further expansion. Antigonus treated them warily throughout his reign.

The Mind

Materialism – which, for almost all purposes, is the same as physicalism – is the theory that everything that exists is material. Natural science shows that most things are intelligible in material terms, but mind presents problems in at least two ways. The first is consciousness, as found in the ‘raw feel’ of subjective experience. The second is the intentionality of thought, which is the property of being about something beyond itself; ‘aboutness’ seems not to be a physical relation in the ordinary sense. There have been three ways of approaching these problems. The hardest is eliminativism, according to which there are no ‘raw feels’, no intentionality and, in general, no mental states: the mind and all its furniture are part of an outdated science that we now see to be false. Next is reductionism, which seeks to give an account of our experience and of intentionality in terms which are acceptable to a physical science: this means, in practice, analysing the mind in terms of its role in producing behaviour. Finally, the materialist may accept the reality and irreducibility of mind, but claim that it depends on matter in such an intimate way – more intimate than mere causal dependence – that materialism is not threatened by the irreducibility of mind. The first two approaches can be called ‘hard materialism’, the third ‘soft materialism’. The problem for eliminativism is that we find it difficult to credit that any belief that we think and feel is a theoretical speculation. Reductionism’s main difficulty is that there seems to be more to consciousness than its contribution to behaviour: a robotic machine could behave as we do without thinking or feeling. The soft materialist has to explain supervenience in a way that makes the mind not epiphenomenal without falling into the problems of interactionism.

AbstractParakeets in the genus Pyrrhura occur in Amazonia and in almost all other major Neotropical forests. Their uneven distribution (with some widespread and several geographically restricted endemic taxa) and complex patterns of plum- age variation have long generated a confused taxonomy. Several taxonomically difficult polytypic species are usually recognized. Here, we present a mitochondrial DNA (mtDNA) phylogenetic analysis of Pyrrhura, with emphasis on the especially problematic picta-leucotis complex, to provide a more robust basis for interpreting the systematics and historical biogeography of the group. Our main findings are that (1) Pyrrhura can be divided into three main evolutionary lineages, one comprising P. cruentata, an Atlantic Forest endemic, the second comprising the picta-leucotis complex, and the third comprising the remaining species; (2) the traditionally recognized species P. picta and P. leucotis are not monophyletic; and (3) most of the species recognized by Joseph (2000, 2002) are diagnosable as independent evolutionary units, with the exception of the following species pairs: P. snethlageae and P. amazonum, P. leucotis and P. griseipectus, and P. roseifrons and P. peruviana. Other than P. cruentata, the two clades that constitute Pyrrhura appear to have radiated and evolved their present mtDNA diversity over short periods during the Plio-Pleistocene.Sistemática Molecular y Patrones de Diversificación en Pyrrhura (Psittacidae), con Énfasis en el Complejo Picta-Leucotis

ABSTRACT Despite numerous barriers to transmission, zoonoses are the major cause of emerging infectious diseases in humans. Among these, severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and ebolaviruses have killed thousands; the human immunodeficiency virus (HIV) has killed millions. Zoonoses and human-to-animal cross-species transmission are driven by human actions and have important management, conservation, and public health implications. The current SARS-CoV-2 pandemic, which presumably originated from an animal reservoir, has killed more than half a million people around the world and cases continue to rise. In March 2020, New York City was a global epicenter for SARS-CoV-2 infections. During this time, four tigers and three lions at the Bronx Zoo, NY, developed mild, abnormal respiratory signs. We detected SARS-CoV-2 RNA in respiratory secretions and/or feces from all seven animals, live virus in three, and colocalized viral RNA with cellular damage in one. We produced nine whole SARS-CoV-2 genomes from the animals and keepers and identified different SARS-CoV-2 genotypes in the tigers and lions. Epidemiologic and genomic data indicated human-to-tiger transmission. These were the first confirmed cases of natural SARS-CoV-2 animal infections in the United States and the first in nondomestic species in the world. We highlight disease transmission at a nontraditional interface and provide information that contributes to understanding SARS-CoV-2 transmission across species. IMPORTANCE The human-animal-environment interface of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an important aspect of the coronavirus disease 2019 (COVID-19) pandemic that requires robust One Health-based investigations. Despite this, few reports describe natural infections in animals or directly link them to human infections using genomic data. In the present study, we describe the first cases of natural SARS-CoV-2 infection in tigers and lions in the United States and provide epidemiological and genetic evidence for human-to-animal transmission of the virus. Our data show that tigers and lions were infected with different genotypes of SARS-CoV-2, indicating two independent transmission events to the animals. Importantly, infected animals shed infectious virus in respiratory secretions and feces. A better understanding of the susceptibility of animal species to SARS-CoV-2 may help to elucidate transmission mechanisms and identify potential reservoirs and sources of infection that are important in both animal and human health.

The proper functioning of a present-day economic system is dependent upon money and prices. This is particularly the case when a large part of the economy is based on private enterprise.For many years economic text-books have stated the three functions of money to be (1) a means of payment, (2) a store of value and (3) a unit of account. The third function will not be considered in this paper, although a study of the controversy that has occurred recently about the correct principles of accountancy at times when prices change substantially will convince the reader that this function is important.Whilst all three functions of money have been recognized for many years, the emphasis given to each has changed radically from time to time. Prior to 1930 almost all the emphasis was given to money as a means of payment. This led to an approach to the subject which has been called the transactions-velocity approach.
