Abstract:

Cat breeds differ enormously in their behavioural disposition, a factor that can impact on the pet-owner relationship, with indirect consequences for animal welfare. This study examined whether lateral bias, in the form of paw preference, can be used as a tool for assessing breed differences in emotional reactivity in the cat. The paw preferences of 4 commonly owned breeds were tested using a food-reaching challenge. Cats were more likely to be paw-preferent than ambilateral. Maine Coons, Ragdolls and Bengals were more likely to be paw-preferent than ambilateral, although only the Bengals showed a consistent preference for using one paw (left) over the other. The strength of the cats’ paw use was related to cat breed, with Persians being more weakly lateralised. Direction of paw use was unrelated to feline breed, but strongly sex-related, with male cats showing a left paw preference and females displaying a right-sided bias. We propose that paw preference measurement could provide a useful method for assessing emotional reactivity in domestic cats. Such information would be of benefit to individuals considering the acquisition of a new cat, and, in the longer term, may help to foster more successful cat-owner relationships, leading to indirect benefits to feline welfare.

Abstract:

Practical relevance: While scratching is a normal, beneficial behavior for cats, it can create problems when cats scratch objects owners deem as inappropriate. However, if veterinarians make suitable recommendations from the first veterinary visit, owners will be able to implement effective preventive strategies to develop good scratching patterns for life. Educating owners as to why cats scratch, how to guide cats to scratch only on desirable surfaces (ie, a scratching post), which types of scratching posts are preferred by most cats, the benefits of pheromone products, as well as other strategies to avoid destructive scratching, helps to preserve the cat–owner bond and reduces the risk of relinquishment. Clinical challenges: Clients may not directly ask veterinarians for their assistance regarding their cat’s destructive scratching, and may not be aware that anything can be done except for declawing their cat. Evidence base: Published studies on scratching are limited. Destructive scratching has been documented as a reason for the relinquishment of cats to shelters and the negative effects of declaw surgeries are being increasingly discovered. Among recent scientific publications are studies assessing kitten and cat preferences for scratching substrates, and the use of pheromones to encourage appropriate scratching behavior. This review draws on these studies, among other resources, as well as the authors’ personal experiences.

Abstract:

ABSTRACT We mapped 226 unique integration sites in human hepatoma cells following gene transfer with a feline immunodeficiency virus (FIV)-based lentivirus vector. FIV integrated across the entire length of the transcriptional units. Microarray data indicated that FIV integration favored actively transcribed genes. Approximately 21% of FIV integrations within transcriptional units occurred in genes regulated by the LEDGF/p75 transcriptional coactivator. DNA in regions of FIV insertion sites exhibited a “bendable” structure and a pattern of duplex destabilization favoring strand separation. FIV integration preferences are more similar to those of primate lentiviruses and distinct from those of Moloney murine leukemia virus, avian sarcoma leukosis virus, and foamy virus.

Abstract:

Each literary era is characterized by certain models of literary animalism with their own semantic accents and symbolism, types of communication “man — animal”, genre preferences. The article examines the features of literary felinistics of the Art Nouveau era, identifies the cultural and social causes of artistic felinophilia. As a material for the study there were three texts written in the period from 1869 to 1939, considered both in the wide cultural context of the modern era, and within the boundaries of their time (modern): “Ménagerie intime”, 1869 by Gaultier T., “The Cats of Copenhagen’’ (1936) by Joyce J. and “Old Possum’s Book of Practical Cats” (1939) by Eliot T. S. In the course of our research, we relied on both historical and literary works devoted to the analysis of specific animalistic images, works of a culturological nature, and also turned to the experience of structuralist studies and the ideas of new posthumanistic knowledge (Human-Animal Studies). The animalistic texts of Gauthier — Joyce — Eliot unite not only the acting cat characters, but also certain artistic perspectives, similar types of human-animal relationships, social and cultural contexts in which their heroes are represented. The feline characters of Gauthier-Joyce-Eliot have much in common: they are anthropomorphic inhabitants of the urban space of the industrial era, leading an appropriate lifestyle and possessing qualities inherent in the middle class. Gautier, Joyce, Eliot’s cats have a bright personality, extraordinary abilities, a lively mind, a rich emotional world, they live according to the laws of human society. They are attractive, intelligent, vital, civilized individuals with unique, eccentric characters (humors).

Abstract:

Felines may find orally administered medicines unpalatable, thus presenting a problem in the treatment of chronic conditions such as hypertension, a commonly diagnosed condition in felines requiring daily administration of medication. A pertinent example is amlodipine besylate, formulations of which are known to be poorly tolerated by cats. There is therefore a need to develop feline-specific delivery approaches that are both simple to administer and mask the taste of the drug, thereby enhancing the owner’s commitment to treatment and the associated therapeutic outcome for the companion animal. In addition, it is helpful to develop accessible and reproducible means of assessing taste for pre-clinical selection, hence the use of recently developed taste biosensor systems for veterinary applications is an area of interest. This study focuses on developing feline-specific amlodipine besylate formulations by improving the taste using a suitable flavouring agent while reducing dosage form size to a 2 mm diameter mini-tablet. The choice of L-lysine as a flavouring agent was based on the dietary and taste preference of cats. The impact of L-lysine on the taste perception of the formulation was evaluated using a biosensor system (E-tongue) fitted with sensors sensitive to bitter tastes. The results showed L-lysine successfully masked bitterness, while the drug release studies suggest that it has no impact on drug dissolution. In addition, tableting parameters such as tablet mass uniformity, content uniformity, tablet diameter, thickness and hardness were all satisfactory. The present study suggests that amlodipine besylate mini-tablets containing L-lysine could improve the palatability and in turn support product acceptability and ease of administration. These data could have an impact on orally administered medicines for cats and other veterinary species through product differentiation and competitive advantage in the companion animal market sector. The study also outlines the use of the electronic tongue as a tool for formulation selection in the veterinary field.

Abstract:

The evolution of the chemical senses has resulted in a sensory apparatus for high taste and smell acuity in mammals and birds to ensure self-nourishment. Such peripheral chemosensory systems function as a code to unfold the nutritional value of feedstuffs. Food ingestion simultaneously evokes odor, taste and thermo-mechanical (somatosensing) sensations. Olfaction represents the capacity to identify feed volatiles that are predominantly derived from essential nutrients in plants. Comparative biology of olfaction shows that primates and chickens have a smaller olfactory epithelium and fewer olfactory receptor (OR) genes than non-primate mammals studied to date including farm and companion animals, such as the pig, the cow, the dog, the cat and the horse. A significant proportion of the total OR genes in mammals and birds have lost their functionality (pseudogenes) in a process that seems to reflect a decrease in the animal’s reliance on the sense of smell, particularly in humans and cows. The taste system allows animals to recognize a diverse repertoire of nutrient (sugars, amino acids, salts, acids and fats) or toxic related chemical entities that provide valuable information about the quality of food. Taste senses non-volatile molecules in the oral cavity through taste receptors (TR). The TR are expressed in the sensory cells forming the taste buds of the tongue’s papillae. Taste cells are linked to a network of solitary chemosensory cells diffused through many non-taste tissues involved in metabolic homeostasis. The number of functional taste receptor genes (TASR) in humans is equivalent to that in other mammals and superior to that in chickens. The TASR family 1 (TAS1R coding for umami and sweet TR) is conserved, in number and type, across the species evaluated, with the exception of the sweet receptor in chicken and feline species. The TASR family 2 (TAS2R coding for bitter TR) shows a strong adaptive capacity to dietary sources and digestive physiology across vertebrates. Pseudogenization (loss of gene functionality) in the TAS2R family seems to be a frequent strategy. The implications of oronasal nutrient sensing related to comparative animal feeding strategies and behaviors such as neophobia, feed refusal and hedonic preferences are discussed. Feed palatability and appetence might be one of the main driving forces in short-term feed consumption. Finally, practical applications relevant to animal production are outlined.

Abstract:

The purpose of this paper is to give an overview of our present knowledge about the feline tecto-thalamo-basal ganglia cortical sensory pathway. We reviewed morphological and electrophysiological studies of the cortical areas, located in ventral bank of the anterior ectosylvian sulcus as well as the region of the insular cortex, the suprageniculate nucleus of the thalamus, caudate nucleus, and the substantia nigra. Microelectrode studies revealed common receptive field properties in all these structures. The receptive fields were extremely large and multisensory, with pronounced sensitivity to motion of visual stimuli. They often demonstrated directional and velocity selectivity. Preference for small visual stimuli was also a frequent finding. However, orientation sensitivity was absent. It became obvious that the structures of the investigated sensory loop exhibit a unique kind of information processing, not found anywhere else in the feline visual system.

Abstract:

Domestic cat embryos typically are cultured in media formulated for somatic cells or embryos from rodents or livestock species. Under these conditions, blastocyst development has been inconsistent and delayed relative to embryos grown in vivo, and embryo viability following transfer has been low. Our goal is to systematically define the culture requirements of the feline embryo to improve embryo development and viability. The objective of this study was to determine the ionic (NaCl, KCl, KH2PO4, and CaCl2:MgSO4) preferences of domestic cat IVF embryos. Anestral female cats were injected (i.m.) with 150IU eCG followed 84h later by 100IUhCG. Oocytes were recovered via laparoscopic follicular aspiration approximately 24h post-hCG injection (Day 0). Semen was collected from one of two males by means of an artificial vagina and washed once in HEPES-buffered IVF medium. Mature cumulus-oocyte complexes were co-incubated with 2.5–5×105 motile sperm mL−1 in IVF medium (100mM NaCl, 4.0mM KCl, 1.0mM KH2 PO4, 2.0mM CaCl2, 1.0mM MgSO4-7H2O, 25.0mM NaHCO3, 3.0mM glucose, 0.1mM pyruvate, 6.0mM L-lactate, 1.0mM glutamine, 0.1mM taurine, 1×MEM nonessential amino acids, 50μgmL−1 gentamicin, and 4.0mgmL−1 BSA) for 19 to 22h in 6% CO2 in air (38.7°C). Cumulus cells were removed and embryos cultured (8–11 embryos/50μL drop; 6% CO2, 5% O2, 89% N2, 38.7°C) in media containing 100.0 or 120.0mM NaCl, 4.0 or 8.0mM KCl, 0.25 or 1.0mM KH2PO4, and 1.0mM:2.0mM or 2.0mM:1.0mM CaCl2:MgSO4 (2×2×2×2 factorial design). The remaining components of the culture medium were identical to the IVF medium (but w/o gentamicin). Development to the blastocyst stage by Day 6, metabolism (glycolysis and pyruvate) of each blastocyst, and final cell number (Hoechst 33342 staining) of all embryos were evaluated. Final cell number of cleaved embryos and development to the blastocyst stage were analyzed using analysis of variance in the GLIMMIX macro of SAS. A total of 236 oocytes were inseminated, yielding 128 cleaved embryos (54%), including 6 blastocysts (4.7% of cleaved embryos). Cell number was not (P>0.05) affected by NaCl, KCl, or KH2PO4 concentrations, but tended (P=0.057) to be higher after culture in 2.0mM:1.0mM CaCl2:MgSO4. Treatments did not significantly affect (P>0.05) development to the blastocyst stage, but numerically more blastocysts were produced in 100.0mM NaCl (4/6), 8.0mM KCl (5/6), or 1.0mM KH2PO4 (5/6). Both CaCl2:MgSO4 ratios resulted in 3 blastocysts. Blastocysts contained 61.08±5.1 (mean±SEM, n=6) cells and actively metabolized glucose (glycolysis, 3.7±0.8pmol/embryo/3h or 0.06±0.01pmol/cell/3h) and pyruvate (0.75±0.27pmol/embryo/3h or 0.013±0.005pmol/cell/3h). These results suggest that the ionic composition of culture media influences the in vitro development of cat IVF embryos. (Supported by NIH grant RR15388.)

Abstract:

A 28S rDNA PCR detection assay was previously developed to identify Dipylidium caninum DNA inside single fleas collected from both cats and dogs. Sequence analysis of the 28S rDNA fragment indicated two genetically distinct variations of the target region. The two genotypes, so-called “D. caninum canine genotype” and “D. caninum feline genotype”, based on host origin, are further investigated and described in this paper. Restriction fragment length polymorphism (RFLP) analysis and hydrolysis probe-based genotyping assays were developed and validated for genotyping D. caninum DNA. The complete mitochondrial (mt) genome of the “feline genotype” was sequenced and compared to the D. caninum mt genome available in GenBank. The molecular characterization of D. caninum isolates collected from infected fleas, and also proglottids collected from dogs and cats, confirmed the existence of two distinct genotypes. These genotypes are related to host origin (dogs or cats), irrespective of their geographical origin, and they present a biological adaptation to their respective host, as confirmed by the comparison of biological development and host preference in another study. The genetic differences (Part 1, present paper) and biological observations (Part 2, in this journal) enabled us to suggest the existence of two distinct species within D. caninum, which will have to be clarified.

Abstract:

ABSTRACT Encapsidation of retroviral RNA involves specific interactions between viral proteins and cis-acting genomic RNA sequences. Human immunodeficiency virus type 1 (HIV-1) RNA encapsidation determinants appear to be more complex and dispersed than those of murine retroviruses. Feline lentiviral (feline immunodeficiency virus [FIV]) encapsidation has not been studied. To gain comparative insight into lentiviral encapsidation and to optimize FIV-based vectors, we used RNase protection assays of cellular and virion RNAs to determine packaging efficiencies of FIV deletion mutants, and we studied replicative phenotypes of mutant viruses. Unlike the case for other mammalian retroviruses, the sequences between the major splice donor (MSD) and the start codon of gag contribute negligibly to FIV encapsidation. Moreover, molecular clones having deletions in this region were replication competent. In contrast, sequences upstream of the MSD were important for encapsidation, and deletion of the U5 element markedly reduced genomic RNA packaging. The contribution of gag sequences to packaging was systematically investigated with subgenomic FIV vectors containing variable portions of the gag open reading frame, with all virion proteins supplied in trans. When no gag sequence was present, packaging was abolished and marker gene transduction was absent. Inclusion of the first 144 nucleotides (nt) of gag increased vector encapsidation to detectable levels, while inclusion of the first 311 nt increased it to nearly wild-type levels and resulted in high-titer FIV vectors. However, the identified proximal gag sequence is necessary but not sufficient, since viral mRNAs that contain all coding regions, with or without as much as 119 nt of adjacent upstream 5′ leader, were excluded from encapsidation. The results identify a mechanism whereby FIV can encapsidate its genomic mRNA in preference to subgenomic mRNAs.

Abstract:

The Cuban fossil avifauna, prior to this study, included 30 extinct and extirpated valid taxa. In the present contribution, we review the fossil avifauna from Las Breas de San Felipe, and in so doing increase the diversity of Cuban fossil birds to 36 species with the description of a New World vulture, Coragyps seductus sp. nov., three accipitrids, Gigantohierax itchei sp. nov., Buteogallus royi sp. nov., and Buteo sanfelipensis sp. nov., a small caracara, Milvago diazfrancoi sp. nov., plus Buteogallus cf. B. fragilis (L. Miller, 1911), which is recorded for the first time in Cuba and the Antillean Subregion. Of the total of 34 bird species now registered from Las Breas de San Felipe, 21 (61.8 %) are extinct and 13 (38.2 %) correspond to species that still live in Cuba, other Antillean islands, or in the American continent. Raptors dominate the assemblage, with 26 (76.5 %) species. These are mostly from Accipitridae and Falconidae, and 19 (55.9 %) are diurnal and 7 (20.6 %) nocturnal. This abundance of raptors in Las Breas de San Felipe is similar to the composition from other asphalt deposits known from the American continent such as Rancho La Brea. The palaeoavifauna from this locality can be split, according to ecological preferences, into three groups or guilds. Radiocarbon (14C) dates indicate a late Pleistocene age for some of the recovered bird remains, including those of Antigone cubensis (Fischer & Stephan, 1971) comb. nov., Gymnogyps varonai (Arredondo, 1971) and Ornimegalonyx oteroi (Arredondo, 1958).

Abstract:

Background: Fluralaner is a novel isoxazoline compound and the only systemically distributed ectoparasiticide approved in the United States for redosing at up to 12-week intervals for flea and tick control in cats. Other feline ectoparasiticides, including other systemic isoxazolines, are approved for redosing at monthly intervals. A survey developed in 2016 to assess the satisfaction, preference, and adherence of dog owners prescribed fluralaner as an ectoparasiticide with the treatment and veterinary flea and tick protection recommendations was adapted for completionby cat owners in the USA. Aim: The study objective was to use cat-owner survey data obtained at US veterinary practices to assess client satisfaction and utilization practices for fluralaner, and to evaluate owner adherence to current flea and tick control recommendations. Methods: US veterinary practices (n = 26) were asked to obtain completed surveys for up to 25 active clients who were currently treating their cats with a topical preparation of fluralaner for flea and tick control. Clients who had previously used flea and tick products for cats other than fluralaner were enrolled in the study. Participating cat owners completed an 11-question survey on their satisfaction with, preference for, and adherence to treatment recommendations for topically applied fluralaner as a feline flea and tick control medication. Results: The average cat in this study had a mean (± SD) body weight of 5.1 (± 0.9) kg and was 7.1 (±1.4) years old. Most cats lived in a home versus an apartment and more than half spent some time outside. Satisfaction was assessed with a 5-point Likert scale, with nearly all cat owners (97%) indicating that they were satisfied or very satisfied with fluralaner. Most of them (66%) had previously used other monthly flea and tick products for cats. Owners were not excluded if they had previously used a canine flea and tick product. The extended dosing interval up to 12 weeks was the most frequently selected benefit of fluralaner. Nearly 9 out of 10 respondents indicated they readministered fluralaner mostly on time or delayed by a few days, and most said they were more likely to give a repeat dose of fluralaner at the recommended redosing interval compared to monthly products. 87% of the responding cat owners preferred topical fluralaner over the monthly flea and tick products they had used. Conclusion: The extended dosing interval of up to 12 weeks was the leading preference factor and the key driver of user satisfaction with fluralaner leading to improved adherence to redosing recommendations. Cat owners said they were more likely to administer fluralaner at the recommended redosing interval compared to monthly products, indicating that less frequent redosing contributes to improved adherence.

Abstract:

The usefulness of isolated adult cardiac myocytes, both in suspension and in culture, as a model system for measuring cardiotoxicity is evaluated. It has been suggested that isolated adult myocytes should preferably be cultured for such experimentation, as this restores the cells to a physiological preference for fatty acids as a substrate rather than glucose. We show here that the restoration of Ca2+ to cells immediately after isolation results in an artificially enhanced glucose metabolism, as measured by an elevated rate of deoxyglucose uptake. Early restoration of Ca2+ during cell isolation, on the other hand, results in cells with a normal low level of deoxyglucose uptake. We, thus, conclude that cells can be ready for valid toxicity studies immediately after isolation, without the need for culture. The culture of adult feline ventricular cells is also described. These cells, like rabbit but unlike rat, are particularly promising for toxicity studies because they remain quiescent in culture and do not round up. On exposure to norepinephrine, they beat spontaneously and increase their rate of protein synthesis.

Abstract:

La nutria marina, gato marino o chungungo (Lontra felina) es considerada virtualmente una especie exclusiva marina con una preferencia de hábitat rocosos de litoral en la costa pacíﬁca de Perú y hasta Tierra del Fuego al sur de Chile y la Isla de los Estados en el sur de Argentina. En esta nota cientíﬁca se presentan registros ﬂuviales de la nutria marina. En el río Cotahuasi (cuenca del río Ocoña) se tiene un registro hasta la localidad de Sipia, a 171 Km del litoral y a 1 994 m de altitud. En la cuenca del río Colca (cuenca Majes), el registro más alejado es en la laguna Mamacocha en la provincia de Caylloma, a 157 Km del mar a una altitud de 1 702 m.Se presentan además otros registros directos e indirectos hasta la desembocadura de estas cuencas. El registro de esta especie en dos de los ríos más grandes del suroeste de Perú y no en los demás (departamentos de Moquegua y Tacna), posiblemente se deba a la conﬁguración extremadamente encañonada, lo que puede representar un refugio para esta especie amenazada, además de tener una abundante oferta alimenticia. Se considera necesario incluir acciones de conservación en la distribución ﬂuvial de la nutria de mar, debido a que actividades como la construcción de presas, afectarían signiﬁcativamente su presencia en este espacio y hábitat de su distribución, en gran medida desconocido.

Abstract:

ABSTRACT Cytopathic, T-cell-tropic feline leukemia viruses (FeLV-T) evolve from FeLV-A in infected animals and demonstrate host cell specificities that are distinct from those of their parent viruses. We recently identified two cellular proteins, FeLIX and Pit1, required for productive infection by these immunodeficiency-inducing FeLV-T variants (M. M. Anderson, A. S. Lauring, C. C. Burns, and J. Overbaugh, Science 287:1828–1830, 2000). FeLV-T is the first example of a naturally occurring type C retrovirus that requires two proteins to gain entry into target cells. FeLIX is an endogenous protein that is highly related to the N-terminal portion of the FeLV envelope protein, which includes the receptor-binding domain. Pit1 is a multiple-transmembrane phosphate transport protein that also functions as a receptor for FeLV-B. The FeLV-B envelope gene is derived by recombination with endogenous FeLV-like sequences, and its product can functionally substitute for FeLIX in facilitating entry through the Pit1 receptor. In the present study, we tested other retrovirus envelope surface units (SUs) with their cognate receptors to determine whether they also could mediate infection by FeLV-T. Cells were engineered to coexpress the transmembrane form of the envelope proteins and their cognate receptors, or SU protein was added as a soluble protein to cells expressing the receptor. Of the FeLV, murine leukemia virus, and gibbon ape leukemia virus envelopes tested, we found that only those with receptor-binding domains derived from endogenous FeLV could render cells permissive for FeLV-T. We also found that there is a strong preference for Pit1 as the transmembrane receptor. Specifically, FeLV-B SUs could efficiently mediate infection of cells expressing the Pit1 receptor but could only inefficiently mediate infection of cells expressing the Pit2 receptor, even though these SUs are able to bind to Pit2. Expression analysis of feline Pit1 and FeLIX suggests that FeLIX is likely the primary determinant of FeLV-T tropism. These results are discussed in terms of current models for retrovirus entry and the interrelationship among FeLV variants that evolve in vivo.

Abstract:

ABSTRACTThe procyonid †Cyonasua is endemic to South America and recorded from the Late Miocene to the Early Pleistocene. This paper studies the forelimb of †Cyonasua sp. (late Pliocene of Miramar, Argentina), using an ecomorphological approach to infer morphological adaptations linked to substrate preference and locomotory mode, as well as to grasping and digging ability. Twenty linear measurements of forelimb and pectoral girdle were taken from †Cyonasua sp. and a sample of 87 specimens of extant carnivoran families (Procyonidae, Mustelidae, Ursidae, Viverridae, Canidae and Felidae). Raw values were transformed to minimise the effect of size. Morphological variation was explored by principal component analysis (PCA); substrate preference and locomotory mode were further analysed by multivariate analysis of variance (MAV) and discriminant analysis (DA); grasping and digging ability were analysed by DA. In the PCA morphospace, †Cyonasua sp. occupied a unique position, close to extant procyonids. DA classified it as non-specialised digger with poor grasping ability. The results lead to the interpretation of †Cyonasua sp. as having a moderately stabilised elbow joint with poor pronation–supination, although some climbing skills cannot be ruled out. Thus, †Cyonasua sp. could have had generalised habits, in agreement with reconstructed palaeoenvironmental conditions.

La relación que tuvieron con el edificio los sucesores de Felipe II y más tarde los primeros Borbones fue muy variada, y ello se debió tanto a sus preferencias respecto al uso estacional en los Reales Sitios, como a cuestiones de gusto y comodidad. Como consecuencia, durante los siglos XVII y XVIII las imágenes del Monasterio se actualizaron y completaron con otras que describían los elementos nuevos, y con vistas del interior y del exterior.

Abstract:

We evaluated current uses of wild mammals by indigenous and mestizo communities in Mexico by extracting data from 59 sources published or produced between 1987–2017, covering data from 240 localities and 3,905 questionnaires. We then calculated a Cultural Value Index (CVI) previously applied to plants to quantify resource use and assess the cultural significance of each mammal. A total of 82 species were reported, and the animals with the highest cultural importance according to their CVI (in brackets) were two species of deer (Odocoileus virginianus [18.32] and Mazama temama [10.04]), as well as the nine-banded armadillo (Dasypus novemcinctus [14.18]), white-nosed coati (Nasua narica [14.75]), collared peccary (Pecari tajaccu [11.90]), northern raccoon (Procyon lotor [11.28]) and spotted paca (Cuniculus paca [9.84]). The most common uses were for food, to reduce the damage or harm they cause, and for medicinal purposes, with O. virginianus, P. lotor, N. narica, and D. novemcinctus frequently hunted for all these reasons. Our analysis also highlighted the hunting of rarer species of national conservation concern, including commercial trading of body parts of the felids Panthera onca, Leopardus pardalis, and Leopardus wiedii. By quantifying the ethnozoological significance of wildlife to indigenous communities, indices such as CVI provide a robust measure of the extent of use and preference for particular species or taxa. This adds to the body of evidence used to develop effective regulations and laws related to harvesting and hunting, and helps promote a more sustainable and long-term approach to the use of natural resources.

Abstract:

Social networks are a fundamental tool that organizations use for promotional, informative and relational purposes. From this last point of view, social networks allow organizations to gain visibility and generate interaction with audiences, thus contributing to maintaining mutually beneficial relationships with them. In the sports field, as in others, the use of social networks is widespread not only by sports clubs or entities, but also by individual athletes. Instagram in particular is one of the networks that has experienced the greatest growth in recent years and that is why, from the international academic field, attention has been paid to the use of this network in the sports field. Based on this approach, this research analyzes the use of Instagram by Spanish athletes of recognized prestige, with the aim of evaluating its effectiveness as a mechanism to generate interaction and promote relations with the public. From this perspective, questions such as the effectiveness of Instagram to generate visibility or the influence of various elements, such as the type of post or the complementary resources used in the text, in the generation or increase of interaction are raised. The study focuses on a sample of 17 Spanish adult athletes who received a “Premio Nacional del Deporte” (Rey Felipe, Reina Letizia, Rey Juan Carlos and Reina Sofía) between 2013 and 2017. For each of the selected athletes a compilation of all their Instagram posts for the year 2018, using the Instagram Scraper tool, was made and an analysis of emission and reception was carried out. Regarding the emission, aspects such as the number of published posts, the type of post (image or video) and the use of resources such as hashtags, mentions and emoticons were taken into account, while from the point of view of reception they were collected data of number of followers, likes and comments. The results show a high diversity both in the number of published posts, which range between 39 and 348 entries per year, and in the number of followers, which varies notably depending on the notoriety of the athlete, from the little more from 16,000 by Ruth Beithia to over 27 million Andrés Iniesta. There is a majority preference for the use of images (82% of posts) compared to the use of videos, although the use of complementary resources such as hashtags, mentions and emoticons is highly variable depending on the athlete and does not seem to significantly influence in generating interaction. It is also verified that the members of the sample are not very active in following other accounts, since the number of followers is barely over 1,200 at best. The total of the publications accumulates almost 230 million likes and more than a million and a half comments, although the difference in results per athlete in these indicators is highly variable. In general terms, more followers generate more likes and more comments, although this increase is not proportional and no significant increase in interaction is generated from very high numbers of followers. These results corroborate the interest of Instagram as a network with high capacity to generate visibility and interaction with audiences, although the popularity of the athlete influences, in the first place, the number of followers and, therefore, the possibilities of interaction.

PICO questionIn adult cats with idiopathic epilepsy, which is poorly controlled with phenobarbital monotherapy, should levetiracetam or imepitoin be used in preference as a second line treatment in order to reduce seizure frequency?Clinical bottom lineThere is currently insufficient evidence to reliably determine whether levetiracetam or imepitoin should be used in preference as a second line treatment for the management of cats with refractory idiopathic epilepsy. There is weak evidence however to suggest clinical efficacy of levetiracetam and imepitoin in management of cats with idiopathic epilepsy. Further studies which evaluate and directly compare the efficacy of second line anticonvulsants in feline epilepsy are needed.

Abstract:

Although categorization abilities may serve as the foundation for most other complex cognitive processes, this topic has been grossly understudied in the order Carnivora. However, there are a growing number of studies examining the abilities of bears, felines, and canines to discriminate among stimuli that could represent conceptual categories. These studies are few in number compared to the extensive work conducted on non-human primates, but, thus far, results suggest that carnivores show comparable abilities to, for example; form natural categories, discriminate quantities, recognize cues of human emotion, and to discriminate kin. There is little existing work exploring concepts of sameness and relational reasoning in carnivores, and work on social concepts, such as representations of mental states, exist only in canines. Future studies are necessary to better understand the mechanisms underlying carnivores’ categorization abilities and conceptual representations. Furthermore, future work should focus on differences in conceptual ability as a function of social lifestyle and dietary preferences within carnivores. Such studies will be helpful in understanding the evolutionary pressures responsible for conceptual processes in a variety of species, including humans.

ABSTRACT Within the last two decades, the international expansion of Latin American companies has undergone remarkable growth. This phenomenon has attracted scholarly attention, however, most of the available research is focused on companies that have already engaged in foreign direct investment (FDI), meanwhile, Latin American firms in pre-FDI stages remain mostly understudied. This article uses an explanatory case study design to analyze the corporate reputation and decision-making process related to international expansion of a set of ten Latin American companies. Both archival and primary data were used in the individual and cross-case analyses stages for 22 months. Our study identifies and establishes analytical generalizations when examining and contrasting the findings with the previously revised theoretical frameworks. More specifically, we identified that these companies exhibit similarities with the behavior of Jaguars, the Latin American wild feline; especially because of (i) their preference to remain in their regional market to exploit current capabilities and advantages, and eventually enter developed markets to upgrade capabilities and surpass strong competitors at home; (ii) their strategies to disguise their country of origin and lack of experience when operating internationally; and (iii) their solitary behavior and reluctance to engage in partnerships and/or strategic alliances unless they have a specific interest in building legitimacy and enhancing reputation.

Abstract:

Abstract While the raw pet food market continues to grow, the risk of bacterial contamination in these types of diets is a major concern, with Salmonella enterica and Listeria monocytogenes being the most frequently associated pathogens in raw pet food product recalls. DL-methionine is included in some commercial feline kibble and canned diets to improve protein quality; however, an alternative to this is a liquid methionine supplement, 2-hydroxy-4-(methylthio)-butanoic acid (HMTBa), which is also an organic acid. HMTBa has previously demonstrated similar efficacy to formic acid against pathogens in a liquid environment and may be a good candidate to inhibit S. enterica and L. monocytogenes in raw ground meat. First, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of HMTBa against these pathogens under laboratory growth conditions were determined by measuring growth of pathogens over 36 h when exposed to 10 concentrations of HMTBa (0.10 – 1.00%) mixed with tryptic soy broth. HMTBa included at ≥ 0.50% was bactericidal to S. enterica and L. monocytogenes (P < 0.05). Next, 5 levels of HMTBa (0.50 – 1.25%) were included in raw ground meat mixtures inoculated with cocktails of S. enterica or L. monocytogenes, and contamination levels were determined at 4 timepoints: immediately, and after refrigerated storage (4 °C) at 24 h, 48 h, and 72 h after removal from freezer (24 h at -20 °C). HMTBa included as 1.25% of the meat mixture reduced S. enterica and L. monocytogenes compared to the control (P < 0.05); however, it did not result in total kill of either of these pathogens. Following this, feeding behaviours of 7 domestic cats were assessed when offered a raw chicken diet treated with or without 1.25% HMTBa for 5 d each, after which a 2-d 2-choice preference test was conducted. Cats demonstrated a preference for raw diets without HMTBa, but still readily consumed diets with 1.25% HMTBa, suggesting that such a diet was still palatable to them.

Abstract The aim of the study was to assess dietary diversity (DD) and associated factors among human immune deficiency virus (HIV)-positive adults attending the anti-retroviral therapy (ART) clinic at Felege Hiwot Comprehensive Specialized Hospital (FHCSH) in Northwest Ethiopia. An institution-based cross-sectional study was conducted at FHCSH in 2019. A systematic random sampling technique was employed to select 352 study subjects. Data were collected using an interviewer-administered questionnaire and chart review. Statistical Package for the Social Science version 26 was used for analysis. A simple and multivariable binary logistic regression was used to determine associated factors. Two hundred and nine (59⋅4 %) adults had consumed a diversified diet. The mean individual DD score was 3⋅86 ± 1⋅18.

This study exhibited that the DD status among adults attending the ART clinic was below two-thirds. Health institutions and health professionals working at ART clinics shall strengthen their efforts to sustain the nutritional counselling service and ART adherence at health institutions and encourage the patients to avoid food preference for their meal. It is vital to ensure the household food security of adults on ART.

Full text

Abstract:

Camera traps have become an important research tool for both conservation biologists and wildlife managers. Recent advances in spatially explicit capture-recapture (SECR) methods have increasingly put camera traps at the forefront of population monitoring programs. These methods allow for benchmark analysis of species density without the need for invasive fieldwork techniques. We conducted a review of SECR studies using camera traps to summarize the current focus of these investigations, as well as provide recommendations for future studies and identify areas in need of future investigation. Our analysis shows a strong bias in species preference, with a large proportion of studies focusing on large felids, many of which provide the only baseline estimates of population density for these species. Furthermore, we found that a majority of studies produced density estimates that may not be precise enough for long-term population monitoring. We recommend simulation and power analysis be conducted before initiating any particular study design and provide examples using readily available software. Furthermore, we show that precision can be increased by including a larger study area that will subsequently increase the number of individuals photo-captured. As many current studies lack the resources or manpower to accomplish such an increase in effort, we recommend that researchers incorporate new technologies such as machine-learning, web-based data entry, and online deployment management into their study design. We also cautiously recommend the potential of citizen science to help address these study design concerns. In addition, modifications in SECR model development to include species that have only a subset of individuals available for individual identification (often called mark-resight models), can extend the process of explicit density estimation through camera trapping to species not individually identifiable.

Abstract:

El presente documento fue creado de la necesidad de determinar la factibilidad de la elaboración de pan en la región Huasteca, ya que en esta región se tiene pan, elaborado de manera artesanal, lo cual implica que su costo sea alto, debido a la cantidad de producción, se busca la forma de realizar una combinación del plan tradicional y la diversidad de pan elaborador de manera industrial mejorando la calidad y el costo, como: 1.- pan artesanal huasteco que es una joya culinaria de la región huasteca donde trataremos de incorporarlo primero al mercado local para después incursionar en el mercado regional y nacional 2.- el pan francés (bolillos) y los baguettes que son de gran consumo por los clientes locales para la elaboración de bocadillos y sándwiches 3.- el pan dulce comercial, este es el pan que se ofrece en las principales panaderías industriales, donde competiremos activamente con ellos mejorando esos productos con los sabores y la mayor calidad para interesar el paladar del mercado objetivo. De acuerdo a los estudios realizados se determina que se debe contar con unas instalaciones de 25 m2 de construcción de paredes de block y loza de cemento para el área de almacén y otra construcción anexa de 100 m2 con todas las medidas necesarias para mantener la mayor limpieza e higiene donde se llevaran a cabo los procesos de elaboración y horneado de los diferentes productos que se ofrezcan.

Abstract:

Introduction In this article, we hypothesise how mainstream media coverage can promote the spread of disinformation about Covid-19. Mainstream media are often discussed as opposed to disinformation (Glasser; Benkler et al.). While the disinformation phenomenon is related to the intentional production and spread of misleading and false information to influence public opinion (Fallis; Benkler et al.), mainstream media news is expected to be based on facts and investigation and focussed on values such as authenticity, accountability, and autonomy (Hayes et al.). However, journalists might contribute to the spread of disinformation when they skip some stage of information processing and reproduce false or misleading information (Himma-Kadakas). Besides, even when the purpose of the news is to correct disinformation, media coverage might contribute to its dissemination by amplifying it (Tsfati et al.). This could be particularly problematic in the context of social media, as users often just read headlines while scrolling through their timelines (Newman et al.; Ofcom). Thus, some users might share news from the mainstream media to legitimate disinformation about Covid-19. The pandemic creates a delicate context, as journalists are often pressured to produce more information and, therefore, are more susceptible to errors. In this research, we focussed on the hypothesis that legitimate news can contribute to the spread of disinformation on social media through headlines that reinforce disinformation discourses, even though the actual piece may frame the story differently. The research questions that guide this research are: are URLs with headlines that reinforce disinformation discourses and other mainstream media links shared into the same Facebook groups? Are the headlines that support disinformation discourses shared by Facebook users to reinforce disinformation narratives? As a case study, we look at the Brazilian disinformation context on Covid-19. The discussion about the disease in the country has been highly polarised and politically framed, often with government agents and scientists disputing the truth about facts on the disease (Araújo and Oliveira; Recuero and Soares; Recuero et al.). Particularly, the social media ecosystem seems to play an important role in these disputes, as Brazilian President Jair Bolsonaro and his supporters use it as a key channel to spread disinformation about the virus (Lisboa et al.; Soares et al.). We use data from public groups on Facebook collected through CrowdTangle and a combination of social network analysis and content analysis to analyse the spread and the content of URLs and posts. Theoretical Background Disinformation has been central to the Covid-19 “infodemic”, created by the overabundance of information about the pandemic, which makes it hard for people to find reliable guidance and exacerbates the outbreak (Tangcharoensathien et al.). We consider disinformation as distorted, manipulated, or false information intentionally created to mislead someone (Fallis; Benkler et al.). Disinformation is often used to strengthen radical political ideologies (Benkler et al.). Around the world, political actors politically framed the discussion about the pandemic, which created a polarised public debate about Covid-19 (Allcott et al., Gruzd and Mai; Recuero and Soares). On social media, contexts of polarisation between two different political views often present opposed narratives about the same fact that dispute public attention (Soares et al.). This polarisation creates a suitable environment for disinformation to thrive (Benkler et al.) The polarised discussions are often associated with the idea of “bubbles”, as the different political groups tend to share and legitimate only discourses that are aligned with the group's ideological views. Consequently, these groups might turn into ideological bubbles (Pariser). In these cases, content shared within one group is not shared within the other and vice versa. Pariser argues that users within the bubbles are exposed exclusively to content with which they tend to agree. However, research has shown that Pariser’s concept of bubbles has limitations (Bruns), as most social media users are exposed to a variety of sources of information (Guess et al.). Nevertheless, polarisation might lead to different media diets and disinformation consumption (Benkler et al.). That is, users would have contact with different types of information, but they would choose to share certain content over others because of their political alignment (Bruns). Therefore, we understand that bubbles are created by the action of social media users who give preference to circulate (through retweets, likes, comments, or shares) content that supports their political views, including disinformation (Recuero et al.). Thus, bubbles are ephemeral structures (created by users’ actions in the context of a particular political discussion) with permeable boundaries (users are exposed to content from the outside) in discussions on social media. This type of ephemeral bubble might use disinformation as a tool to create a unique discourse that supports its views. However, it does not mean that actors within a “disinformation bubble” do not have access to other content, such as the news from the mainstream media. It means that the group acts to discredit and to overlap this content with an “alternative” story (Larsson). In addition, the mainstream media might disseminate false or inaccurate disinformation (Tsfati et al.). Particularly, we focus on inaccurate headlines that reinforce disinformation narratives, as social media users often only read news headlines (Newman et al.; Ofcom). This is especially problematic because a large number of social media users are exposed to mainstream media content, while exposure to disinformation websites is heavily concentrated on only a few users (Guess et al.; Tsfati et al.). Therefore, when the mainstream media disseminate disinformation, it is more likely that a larger number of social media users will be exposed to this content and share it into ideological bubbles. Based on this discussion, we aim to understand how the mainstream media contribute to the spread of disinformation discourses about Covid-19. Methods This study is about how mainstream media coverage might contribute to the spread of disinformation about Covid-19 on Facebook. We propose two hypotheses, as follows: H1: When mainstream media headlines frame the information in a way that reinforces the disinformation narrative, the links go into a “disinformation bubble”. H2: In these cases, Facebook users might use mainstream media coverage to legitimate disinformation narratives. We selected three case studies based on events that created both political debate and high media coverage in Brazil. We chose them based on the hypothesis that part of the mainstream media links could have produced headlines that support disinformation discourses, as the political debate was high. The events are: On 24 March 2020, Brazilian President Jair Bolsonaro made a public pronouncement on live television. In the week before the pronouncement, Brazilian governors decided to follow World Health Organisation (WHO) protocols and closed non-essential business. In his speech, Bolsonaro criticised social distancing measures. The mainstream media reproduced some of his claims and claims from other public personalities, such as entrepreneurs who also said the protocols would harm the economy. On 8 June 2020, a WHO official said that it “seems to be rare that an asymptomatic person transmits [Covid-19] onward to a secondary individual”. Part of the mainstream media reproduced the claim out of context, which could promote the misperception that both asymptomatic and pre-symptomatic persons (early stages of an illness, before the first symptoms) do not transmit Covid-19 at all. On 9 November 2020, Brazil’s national sanitary watchdog Anvisa reported that they had halted the clinical studies on the CoronaVac vaccine, developed by the Chinese company Sinovac. Bolsonaro often criticised CoronaVac because it was being produced in partnership with São Paulo’s Butantan Institute and became the subject of a political dispute between Bolsonaro and the Governor of São Paulo, João Dória. Bolsonaro said the halt of the CoronaVac trial was "another victory for Jair Bolsonaro". Anvisa halted the trail after a "severe adverse event". The mainstream media rapidly reverberated the decision. Later, it was revealed that the incident was a death that had nothing to do with the vaccine. Before we created our final dataset that includes links from the three events together, we explored the most shared URLs in each event. We used keywords to collect posts shared in the public groups monitored by CrowdTangle, a tool owned by Facebook that tracks publicly available posts on the platform. We collected posts in a timeframe of three days for each event to prevent the collection of links unrelated to the cases. We collected only posts containing URLs. Table 1 summarises the data collected. Table 1: Data collected Dates March 24-26 2020 June 8-10 2020 November 9-11 2020 Keywords “Covid-19” or “coronavirus” and “isolation” or “economy” “Covid-19” or “coronavirus” and “asymptomatic” “vaccine” and “Anvisa” or “CoronaVac” Number of posts 4780 2060 3273 From this original dataset, we selected the 60 most shared links from each period (n=180). We then filtered for those which sources were mainstream media outlets (n=74). We used content analysis (Krippendorff) to observe which of these URLs headlines could reinforce disinformation narratives (two independent coders, Krippendorff’s Alpha = 0.76). We focussed on headlines because when these links are shared on Facebook, often it is the headline that appears to other users. We considered that a headlined reinforced disinformation discourses only when it was flagged by both coders (n=21 – some examples are provided in Table 3 in the Results section). Table 2 provides a breakdown of this analysis. Table 2: Content analysis Event Mainstream media links Headlines that support disinformation discourses Number of links Number of posts Economy and quarantine 24 7 112 Asymptomatic 22 7 163 Vaccine trial 28 7 120 Total 74 21 395 As the number of posts that shared URLs with headlines that supported disinformation was low (n=395), we conducted another CrowdTangle search to create our final dataset. We used a sample of the links we classified to create a “balanced” dataset. Out of the 21 links with headlines that reinforced disinformation, we collected the 10 most shared in public groups monitored by CrowdTangle (this time, without any particular timeframe) (n=1346 posts). In addition, we created a “control group” with the 10 most shared links that neither of the coders considered could reinforce disinformation (n=1416 posts). The purpose of the “control group” was to identify which Facebook groups tend to share mainstream media links without headlines that reinforce disinformation narratives. Therefore, our final dataset comprises 20 links and 2762 posts. We then used social network analysis (Wasserman and Faust) to map the spread of the 20 links. We created a bipartite network, in which nodes are (1) Facebook groups and (2) URLs; and edges represent when a post within a group includes a URL from our dataset. We applied a modularity metric (Blondel et al.) to identify clusters. The modularity metric allows us to identify “communities” that share the same or similar links in the network map. Thus, it helped us to identify if there was a “bubble” that only shares the links with headlines that support disinformation (H1). To understand if the disinformation was supporting a larger narrative shared by the groups, we explored the political alignments of each cluster (H2). We used Textometrica (Lindgreen and Palm) to create word clouds with the most frequent words in the names of the cluster groups (at least five mentions) and their connections. Finally, we also analysed the posts that shared each of the 10 links with headlines that reinforced disinformation. This also helped us to identify how the mainstream media links could legitimate disinformation narratives (H2). Out of the 1346 posts, only 373 included some message (the other 973 posts only shared the link). We used content analysis to see if these posts reinforced the disinformation (two independent coders – Krippendorff’s Alpha = 0.723). There were disagreements in the categorisation of 27 posts. The two coders reviewed and discussed the classification of these posts to reach an agreement. Results Bubbles of information In the graph (Figure 1), red nodes are links with headlines that support disinformation discourses, blue nodes are the other mainstream media links, and black nodes are Facebook groups. Our first finding is that groups that shared headlines that support disinformation rarely shared the other mainstream media links. Out of the 1623 groups in the network, only 174 (10.7%) shared both a headline that supports disinformation discourse, and another mainstream media link; 712 groups (43.8%) only shared headlines that support disinformation; and 739 groups (45.5%) only shared other links from the mainstream media. Therefore, users’ actions created two bubbles of information. Figure 1: Network graph The modularity metric confirmed this tendency of two “bubbles” in the network (Figure 2). The purple cluster includes seven URLs with headlines that support disinformation discourse. The green cluster includes three headlines that support disinformation discourse and the other 10 links from the mainstream media. This result partially supports H1: When mainstream media headlines frame the information in a way that reinforces the disinformation narrative, the links go into a “disinformation bubble”. As we identified, most of the headlines that support disinformation discourse went into a separate “bubble”, as users within the groups of this bubble did not share the other links from the mainstream media. Figure 2: Network graph with modularity This result shows that users’ actions boost the creation of bubbles (Bakshy et al.), as they choose to share one type of content over the other. The mainstream media are the source of all the URLs we analysed. However, users from the purple cluster chose to share only links with headlines that supported disinformation discourses. This result is also related to the political framing of the discussions, as we explore below. Disinformation and Political Discourse We used word clouds (Lindgreen and Palm) to analyse the Facebook groups’ names to explore the ideological affiliation of the bubbles. The purple bubble is strongly related to Bolsonaro and his discourse (Figure 3). Bolsonaro is the most frequent word. Other prevalent words are Brazil, patriots (both related to his nationalist discourse), right-wing, conservative, military (three words related to his conservative discourse and his support of the military dictatorship that ruled Brazil from 1964 to 1985), President, support, and Alliance [for Brazil] (the name of his party). Some of the most active groups within the purple bubble are “Alliance for Brazil”, “Bolsonaro 2022 [next presidential election]”, “Bolsonaro’s nation 2022”, and “I am right-wing with pride”. Figure 3: Purple cluster word cloud Bolsonaro is also a central word in the green cluster word cloud (Figure 4). However, it is connected to other words such as “against” and “out”, as many groups are anti-Bolsonaro. Furthermore, words such as left-wing, Workers’ Party (centre-left party), Lula and Dilma Rousseff (two Workers’ Party ex-presidents) show another ideological alignment in general. In addition, there are many local groups (related to locations such as Rio de Janeiro, São Paulo, Rio Grande do Sul, Minas Gerais, and others), and groups to share news (news, newspaper, radio, portal). “We are 70 per cent [anti-Bolsonaro movement]”, “Union of the Left”, “Lula president”, and “Anti-Bolsonaro” are some of the most active groups within the green cluster. Figure 4: Green cluster word cloud Then, we analysed how users shared the mainstream media links with headlines that support disinformation discourses. In total, we found that 81.8% of the messages in the posts that shared these links also reproduced disinformation narratives. The frequency was higher (86.2%) when considering only posts that shared one of the seven links from the purple cluster (based on the modularity metric). Consequently, it was lower (64%) in the messages that shared one of the other three links. The messages often showed support for Bolsonaro; criticised other political and health authorities (the WHO, São Paulo Governor João Dória, and others), China, and the “leftists” (all opposition to Bolsonaro); claimed that quarantine and social distancing measures were unnecessary; and framed vaccines as dangerous. We provide some examples of headlines and posts in Table 3 (we selected the most-shared URL for each event to illustrate). This result supports H2 as we found that users shared mainstream media headlines that reinforce disinformation discourse to legitimate the disinformation narrative; and that it was more prevalent in the purple bubble. Table 3: Examples of headlines and posts Headline Post "Unemployment is a crisis much worse than coronavirus", says Bolsonaro Go to social media to support the President. Unemployment kills. More than any virus... hunger, depression, despair and everything UNEMPLOYMENT, THE DEPUTIES CHAMBER, THE SENATE AND THE SUPREME COURT KILL MORE THAN COVID19 Asymptomatic patients do not boost coronavirus, says WHO QUARANTINE IS FAKE #StayHome, the lie of the century! THIS GOES TO THE PUPPETS OF THE COMMUNIST PARTIES THE AND FUNERARY MEDIA Anvisa halts Coronavac vaccine trial after "serious adverse event" [The event] is adverse and serious, so the vaccine killed the person by covid And Doria [Governor of São Paulo and political adversary of Bolsonaro] wants to force you to take this shit This result shows that mainstream media headlines that support disinformation narratives may be used to reinforce disinformation discourses when shared on Facebook, making journalists potential agents of disinformation (Himma-Kadakas; Tsfati et al.). In particular, the credibility of mainstream news is used to support an opposing discourse, that is, a disinformation discourse. This is especially problematic in the context of Covid-19 because the mainstream media end up fuelling the infodemic (Tangcharoensathien et al.) by sharing inaccurate information or reverberating false claims from political actors. Conclusion In this article, we analysed how the mainstream media contribute to the spread of disinformation about Covid-19. In particular, we looked at how links from the mainstream media with headlines that support disinformation discourse spread on Facebook, compared to other links from the mainstream media. Two research questions guided this study: Are URLs with headlines that reinforce disinformation discourses and other mainstream media links shared into the same Facebook groups? Are the headlines that support disinformation discourses shared by Facebook users to reinforce disinformation narratives? We identified that (1) some Facebook groups only shared links with headlines that support disinformation narratives. This created a “disinformation bubble”. In this bubble, (2) Facebook users shared mainstream media links to reinforce disinformation – in particular, pro-Bolsonaro disinformation, as many of these groups had a pro-Bolsonaro alignment. In these cases, the mainstream media contributed to the spread of disinformation. Consequently, journalists ought to take extra care when producing news, especially headlines, which will be the most visible part of the stories on social media. This study has limitations. We analysed only a sample of links (n=20) based on three events in Brazil. Other events and other political contexts might result in different outcomes. Furthermore, we used CrowdTangle for data collection. CrowdTangle only provides information about public posts in groups monitored by the tool. Therefore, our result does not represent the entire Facebook.

Kolomytseva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00042 Abstract: This study was aimed at examining the influence of succession cropping on the economic efficiency of no-till field crop rotations on the black earth in the zone of unstable moistening of the Stavropol krai. A long-term stationary experiment was conducted to examine for the purpose nine field crop rotation patterns different in the number of fields (four to six), set of crops, and their succession in crop rotation. The respective shares of legumes, oilseeds, and cereals in the cropping pattern were 17 to 33, 17 to 40, and 50 to 67 %. It has been established that in case of no-till field crop cultivation the economic efficiency of plant production depends on the set of crops and their succession in rotation. The most economically efficient type of crop rotation is the soya-winter wheat-peas-winter wheat-sunflower-corn six-field rotation with two fields of legumes: in this rotation 1 ha of crop rotation area yields 3 850 grain units per ha at a grain unit prime cost of 5.46 roubles; the plant production output return and profitability were 20,888 roubles per ha and 113 %, respectively. The high production profitabilities provided by the soya-winter wheat-sunflower four-field and the soya-winter-wheat-sunflower-corn-winter wheat five-field crop rotation are 108.7 and 106.2 %, respectively. The inclusion of winter wheat in crop rotation for two years in a row reduces the second winter wheat crop yield by 80 to 100 %, which means a certain reduction in the grain unit harvesting rate to 3.48-3.57 thousands per ha of rotation area and cuts the production profitability down to 84.4-92.3 %. This is why, no-till cropping should not include winter wheat for a second time Keywords: No-till technology,crop rotation,predecessor,yield,return,profitability, Refference: I Badakhova G.

View | Download DEVELOPMENT AND TESTING OF AUTONOMOUS PORTABLE SEISMOMETER DESIGNED FOR USE AT ULTRALOW TEMPERATURES IN ARCTIC ENVIRONMENT Authors: Mikhail A. Abaturov,Yuriy V. Sirotinskiy, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00043 Abstract: This paper is concerned with solving one of the issues of the general problem of designing geophysical equipment for the natural climatic environment of the Arctic. The relevance of the topic has to do with an increased global interest in this region. The paper is aimed at considering the basic principles of developing and the procedure of testing seismic instruments for use at ultralow climatic temperatures. In this paper the indicated issue is considered through the example of a seismic module designed for petroleum and gas exploration by passive seismoacoustic methods. The seismic module is a direct-burial portable unit of around 5 kg in weight, designed to continuously measure and record microseismic triaxial orthogonal (ZNE) noise in a range from 0.1 to 45 Hz during several days in autonomous mode. The functional chart of designing the seismic module was considered, and concrete conclusions were made for choosing the necessary components to meet the ultralow-temperature operational requirements. The conclusions made served for developing appropriate seismic module. In this case, the components and tools used included a SAFT MP 176065 xc low-temperature lithium cell, industrial-spec electronic component parts, a Zhaofeng Geophysical ZF-4.5 Chinese primary electrodynamic seismic sensor, housing seal parts made of frost-resistant silicone materials, and finely dispersed silica gel used as water-retaining sorbent to avoid condensation in the housing. The paper also describes a procedure of low-temperature collation tests at the lab using a New Brunswick Scientific freezing plant. The test results proved the operability of the developed equipment at ultralow temperatures down to -55°C. In addition, tests were conducted at low microseismic noises in the actual Arctic environment. The possibility to detect signals in a range from 1 to 10 Hz at the level close to the NLNM limit (the Peterson model) has been confirmed, which allows monitoring and exploring petroleum and gas deposits by passive methods. As revealed by this study, the suggested approaches are efficient in developing high-precision mobile seismic instruments for use at ultralow climatic temperatures. The solution of the considered instrumentation and methodical issues is of great practical significance as a constituent of the generic problem of Arctic exploration.

Bogdanov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00044 Abstract: The article considers the problem of surgical correction of the second metatarsal bone length. The article analyzes the results of treatment of patients with excess length of the second metatarsal bones that underwent osteotomy with and without osteosynthesis. The results of treatment of patients who underwent metatarsal shortening due to classical Weil-osteotomy with and without osteosynthesis were analyzed. The first group consisted of 34 patients. They underwent classical Weil osteotomy. The second group included 44 patients in whomosteotomy of the second metatarsal bone were not by the screw. When studying the results of the treatment in the immediate postoperative period, weeks 6, 12, slightly better results were observed in patients of the first group, while one year after surgical treatment the results in both groups were comparable. One year after surgical treatment, there were 2.9% (1 patient) of unsatisfactory results in the first group and 4.5% (2 patients) in the second group. Considering the comparability of the results of treatment in remote postoperative period, the choice of concrete method remains with the operating surgeon.

Shulunova,Alexander I.Sidelnikov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00045 Abstract: Purpose.To determine the quantitative echogenicity indicators (and their ratio) of the layers of stomach and small intestine wall in healthy dogs. Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system Keywords: Ultrasound (US),echogenicity,echogenicity coefficient,digestive system,dogs,stomach,intestines, Refference: I.

Belyayeva,Fatima S. Datieva,Larisa R. Datieva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00046 Abstract: The aim of this work was to assess the functional reserves of the body to quantify individual health; adaptation, psychophysiological characteristics of the health quality of medical students in different seasons of the year. When studying the temporal organization of physiological functions, the rhythm parameters of physiological functions were determined, followed by processing the results using the Cosinor Analysis program, which reveals rhythms with an unknown period for unequal observations, evaluates 5 parameters of sinusoidal rhythms (mesor, amplitude, acrophase, period, reliability). The essence of desynchronization is the mismatch of circadian rhythms among themselves or destruction of the rhythms architectonics (instability of acrophases or their disappearance). Desynchronization with respect to the rhythmic structure of the body is of a disregulatory nature, most pronounced in pathological desynchronization. High neurotism, increased anxiety reinforces the tendency to internal desynchronization, which increases with stress. During examination stress, students experience a decrease in the stability of the temporary organization of the biosystem and the tension of adaptive mechanisms develops, which affects attention, mental performance and the quality of adaptation to the educational process. Time is shortened and the amplitude of the “initial minute” decreases, personal and situational anxiety develops, and the level of psychophysiological adaptation decreases. The results of the work are priority because they can be used in assessing quality and level of health.

Tsvetkov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00047 Abstract: The present study of comparison methods based on the triadic model introduces the following concepts: the relation of comparability and the relation of comparison, and object comparison and attributive comparison. The difference between active and passive qualitative comparison is shown, two triadic models of passive and active comparison and models for comparing two and three objects are described. Triadic comparison models are proposed as an alternative to dyadic comparison models. Comparison allows finding the common and the different; this approach is proposed for the analysis of the nomothetic and ideographic method of obtaining knowledge. The nomothetic method identifies and evaluates the general, while the ideographic method searches for unique in parameters and in combinations of parameters. Triadic comparison is used in systems and methods of argumentation, as well as in the analysis of consistency/inconsistency.
