title: Demands and Resources in Work Mediated by Digital Platforms: A Scoping Review of the Literature

description: Abstract Work arrangements with hiring mediated by digital platforms (digiwork) have grown exponentially in recent years, both in the form of crowdwork and in the form of work on demand via app. However, there is still little systematization regarding knowledge about the elements that characterize this arrangement. Through a scoping review of the literature covering the period from 2005 to 2021, this study sought to identify the digiwork design characteristics, organizing it based on two specific categories: its requirements and the resources available to the worker. For that, it used the model of job demands and resources (JD-R) as a theoretical basis. After applying the inclusion and exclusion criteria, the 43 articles reviewed allowed for the identification of an important imbalance between the demands and resources present in digiwork. It also indicated many missing resources that make it difficult for workers to adequately deal with the demands of both the organization and the task. Among the most prominent demands, imprecision in labor categorization, surveillance via algorithmic management and self-management of risks stand out, while flexibility appears as the most cited resource present, and social protection as the most relevant resource absent. Taken together, the digiwork design characteristics may contribute to the worker's burnout process, in addition to interfering with their motivational process. This generates both suboptimal performance and damage to the worker’s health and well-being.

title: Parasitological diagnosis of fecal samples from domestic dogs from the municipality of Niterói, Rio de Janeiro, Brazil

description: ABSTRACT From 2015 to 2021 the prevalence of parasites was evaluated in fecal samples of dogs from the municipality of Niterói, RJ. The samples were examined at the Laboratory of Diagnostic Support in Parasitic Diseases (LADDP) of the Veterinary School at the Federal Fluminense University (UFF), using centrifugal flotation, sedimentation and mini-FLOTAC techniques. Of the 1,037 samples examined, 30.6% (318/1,037) showed positive results for some parasitic infections, of which 80.5% (256/318) were positive for only one species of parasite and 19.5% (62/318) for multiple infections. Parasitism by Ancylostoma caninum was the most prevalent, with 39% (124/318), followed by Giardia sp., 16% (51/318); Toxocara canis, 14.5% (46/318); Trichuris vulpis, 8.5% (27/318); Cystoisospora canis, 8.5% (27/318); Dipylidium caninum, 7.9% (25/318); and Cryptosporidium sp., 5.6% (18/318). The parasitological diagnosis of dogs in urban areas is the best choice to evaluate the efficacy of control measures adopted for parasitic infections, including those with zoonotic importance.

title: Heterozygosity as a factor of increasing the meat productivity of kalmyk steers

description: ABSTRACT The present work carried out full-genome SNP genotyping of 16-month-old Kalmyk steers to study their productive characteristics and beef quality indicators in the leading farms of the Republic of Kalmykia (Group I was located at the Agrofirma Aduchi farm; Group II at the Kirovsky breeding plant, and Group III at the Plodovitoye agricultural cooperative). As a result of investigating the frequencies of some homozygous alleles, the study established that the heterozygous allele A/A varied considerably along the lines from 0.2785 to 0.3146, while B/B varied from 0.3697 to 0.4125. Meanwhile, the heterozygous allele A/B varied from 0.2986 to 0.3197. Estimated inbreeding coefficients were 1.35, 1.28 and 1.27%. The conducted studies established a higher natural resistance determined by lysozyme, bactericidal and phagocytic activities of steers raised at the Agrofirma Aduchi as farm than their counterparts at the other agricultural enterprises. Over the entire period of the experiment, the steers from 8 to 16 months of age in Group I exceeded the indices of their counterparts in Groups II and III by 30.46g, or 3.31% and 38.04g, or 4.16%, respectively. It is concluded that an increase in the heterozygosity of the studied Kalmyk steers not only results in higher meat productivity, but also improves the quality of carcass and beef quality, increases the yield of more valuable meat grades, and optimizes the fractional composition of proteins.

title: Citizen Participation and Municipality Size: Findings in Light of Demonstrations between 2015 and 2017

description: Abstract Internet democratization and the natural outspread of news reports and information in social media have been changing citizen’s participation at public sphere. The complexity of the current scenario takes to reflections about how participation practices have been taking place in municipalities. Thus, the aim of the present study is to assess what demonstrations show about municipality size and citizen participation within the Brazilian context. A quantitative-qualitative research schedule was developed in order to do so. The qualitative stage of it aimed at facing information gotten from effective participation in demonstrations carried out in municipalities. Results have shown that structural discrepancies among municipalities translate differences seen in citizen participation. If one takes into account what would be the best municipality size for the democratic exercise, the herein analyzed contextual aspects point toward the coexistence of fruitful environments to participation either in small- or large-sized municipalities, although there is the trend of concrete participation in larger municipalities.

title: Investigation of endocrine response of thyroid and intestinal and adipose tissues due to the addition of Moringa oleifera essential oil in diet for quails exposed to heat stress

description: ABSTRACT In this study, we aimed to determine the effect of Moringa oleifera essential oil (MOEO) supplementation to rations of Japanese quail ( Coturnix coturnix japonica ) grown under heat stress (HS) on some adipokine (visfatin, adiponectin, and chemerin), intestinal (citrulline), 3,5,3′-triiodothyronine (T3), thyroxine (T4), and thyroid-stimulation hormone (TSH) levels in the serum. For this purpose, 320 day-old male quail chicks were used. The study was conducted over 42 days, including a 7-d adaptation period and a 35-d experimental period. Eight trial groups were established, each including 10 quail: CT (control temperature, 25 ℃), MOEO 200, MOEO 400, MOEO 600, HSC (HS control), SMOEO 200, SMOEO 400, and SMOEO 600. Based on the results, a dose-dependent decrease was observed on days 21 and 42 in serum adiponectin and T3 in the stress and stress-free groups compared with the control group due to MOEO supplementation. The lowest decrease was observed in the MOEO 600 mg/kg dose group. In addition, an increase in stressed groups was observed when examining serum citrulline levels, while chemerin levels did not have a statistically significant effect. While the decrease in serum visfatin, T4, and TSH levels on the 21st day did not have a statistically significant effect, a significant effect was determined on the 42nd day. The addition of MOEO at 600 mg/kg to the ration may be beneficial in preventing intestinal damage and inflammation that may occur due to HS.

title: Inhibition potential of Caryocar brasiliense on methicillin-resistant Staphylococcus pseudintermedius isolated from the ocular surface of dogs with ophthalmopathies

description: ABSTRACT The indiscriminate use of antibiotics has contributed to the emergence of multiresistant bacteria. Faced with this, the search for antibiotics from plants has proven to be a promising alternative. The objective of this work was to isolate and identify Staphylococcus sp. resistant to methicillin of the ocular surface of dogs with ophthalmopathies and to evaluate its susceptibility to alcoholic extract of the bark and hexane extract of the pulp of Caryocar brasiliense. Biological material was collected from the ocular surface of 21 dogs presenting ophthalmopathies. We isolated 64 S. pseudintermedius, among these, 4 isolates were identified as methicillin-resistant S. pseudintermedius (MRSP). The alcoholic extract of C. brasiliense peel was able to inhibit the bacterial growth of MRSP isolates at a concentration of 2.2%. Thus, the extract from the C. brasiliense peel has antimicrobial potential and represents an alternative in the control of MRSP.

title: Epidemiology of mastitis and interactions of environmental factors on udder health in the compost barn system

description: ABSTRACT This study aimed to describe the epidemiological indexes of mastitis, milk quality and udder hygiene in the Compost Barn system, as well as to search for associations between isolated pathogens from milk with compost characteristics. Three dairy herds participated in the study, and the samples were collected during different periods on each farm. Individual milk samples were collected in duplicate for SCC analysis and microbiological culture. Environmental pathogens caused most cases of clinical mastitis on farm 2, and contagious pathogens caused the most cases on farm 1. Bed moisture was not associated with the incidence of environmental pathogens. Most of the animals remained in good udder hygiene during the study. Poor udder hygiene contributed to the increased incidence of environmental pathogens in one of the farms. A higher number of animals with a hygiene score of ≥ 2 were observed during the warmer and rainfall periods. There was no association between hygiene scores and somatic cell counts. The results suggest that pathogens isolated from milk in animals confined in Compost Barn under tropical climate are like other confinement systems adopted elsewhere. The year period influenced the udder hygiene score, reinforcing the importance of bed management throughout the year.

title: Adjusting Experimental Parameters to Modify Corn Starch with Glycidyl Methacrylate to Tune Specific Properties

description: Chemical modification reactions are viable alternatives for improving the properties of starch because they allow the insertion of molecules that change the original behavior of the polymer. Glycidyl methacrylate (GMA) is an example of a vinylic molecule added to starch to decrease its hydrophilicity and improve mechanical properties. This modification reaction is affected by parameters like the volume of the modifier, time, and temperature. Furthermore, the correlation between these parameters might change the response of an individual parameter on the degree of substitution (DS), crystallinity (Xc), and molecular-weight-related parameters. This work evaluated how these effects and their correlations would affect DS, Xc, molecular weight, and polydispersity index (PDI) of starch. The results suggested that, while higher volumes of GMA and temperatures decreased the DS and Xc, the correlation between them increased the DS by 2.47, and Xc by 1.25. On the other hand, higher temperatures also favored the occurrence of hydrolysis. Also, although none of the parameter correlations had a significant effect on the assessed properties (at 95%), the statistical analysis confirmed that the correlation between two parameters changed the effect of individual parameters.
