Narcisismo: estudantes de contabilidade estão usando seu narcisimo para melhorar o desempenho?

O objetivo dessa pesquisa foi identificar se traços não patológicos de personalidade narcisista em estudantes de graduação de um curso de Ciências Contábeis estariam relacionados com o desempenho desses alunos. Estudantes que superestimam seu desempenho, uma característica de indivíduos narcisistas, vivem uma expectativa não realista que irão ter melhor desempenho que outros em diferentes atividades. Esse comportamento pode ser prejudicial no longo prazo, além de resultar em um constante esforço para que esta expectativa se torne realidade. Os dados foram coletados de uma amostra de 106 alunos de graduação em contabilidade que responderam um questionário contendo questões sobre traços de personalidade narcisista. Os resultados sugerem que quanto maior a presença desses traços narcisitas maiores as chances do desempenho atribuído pelo próprio estudante ser maior. Ao mesmo tempo, o nascisismo não influencia o desempenho real do aluno,o que sugere que esses traços de personalidade incluenciam apenas as expectativas, mas não o processo de aprendizado.The purpose of this research was to identify if non-athological narcissistic personality traits in accounting students are related to their performance. Students who overestimate their performance, a characteristic present in narcissistic individuals, live in the unrealistic belief that they do better than others in different activities. Such tendency can be detrimental in the long term. In addition to resulting in a constant effort so that such expectations become reality. The data were collected from a sample of 106 Brazilian accounting students who responded to a survey that included the Narcissistic Personality Inventory (NPI). The results suggest that the higher the presence of narcissistic traits, the greater his/her self-perceived academic performance. At the same time, narcissism does not influence the student’s real performance, which suggest that narcissistic personality traits just influence expectations, reather than the learning process

Factors associated with incomplete vaccination and negative antibody test results for measles, mumps, and hepatitis A among children followed in the MINA-BRAZIL cohort

Vaccination coverage has been dropping in Brazil and other countries. In addition, immune responses after vaccination may not be homogeneous, varying according to sociodemographic and clinical factors. Understanding the determinants of incomplete vaccination and negative antibody test results may contribute to the development of strategies to improve vaccination effectiveness. In this study, we aimed to investigate the frequency of vaccine adherence, factors associated with incomplete vaccination for measles, mumps, rubella (MMR) and hepatitis A, and factors associated with the seronegative test results for measles, mumps and hepatitis A at 2 years of age. This was a population-based cohort that addressed health conditions and mother/infant nutrition in Cruzeiro do Sul city, Brazil. Vaccination data were obtained from official certificates of immunization. The children underwent blood collection at the two-year-old follow-up visit; the samples were analyzed using commercially available kits to measure seropositivity for measles, mumps, and hepatitis A. We used modified Poisson regression models adjusted for covariates to identify factors associated with incomplete vaccination and negative serology after vaccination. Out of the 825 children included in the study, adherence to the vaccine was 90.6% for MMR, 76.7% for the MMRV (MMR + varicella), and 74.9% for the hepatitis A vaccine. For MMR, after the adjustment for covariates, factors associated with incomplete vaccination included: white-skinned mother; paid maternity leave; raising more than one child; lower number of antenatal consultations; and attending childcare. For hepatitis A, the factors included: white-skinned mother and not having a cohabiting partner. The factors with statistically significant association with a negative antibody test result included: receiving Bolsa Familia allowance for measles and mumps; incomplete vaccination for measles; and vitamin A deficiency for mumps. Strategies to improve the efficiency of vaccine programs are urgently needed. These include improvements in communication about vaccine safety and efficacy, and amplification of access to primary care facilities, prioritizing children exposed to the sociodemographic factors identified in this study. Additionally, sociodemographic factors and vitamin A deficiency may impact the immune responses to vaccines, leading to an increased risk of potentially severe and preventable diseases

Defects controlling electrical and optical properties of electrodeposited Bi doped Cu2O

Doping leading to low electrical resistivity in electrodeposited thin films of Cu2O is a straightforward requirement for the construction of efficient electronic and energy devices. Here, Bi (7 at. %) doped Cu2O layers were deposited electrochemically onto Si(100) single-crystal substrates from aqueous solutions containing bismuth nitrate and cupric sulfate. X-ray photoelectron spectroscopy shows that Bi ions in a Cu2O lattice have an oxidation valence of 3þ and glancing angle X-ray diffraction measurements indicated no presence of secondary phases. The reduction in the electrical resistivity from undoped to Bi-doped Cu2O is of 4 and 2 orders of magnitude for electrical measurements at 230 and 300 K, respectively. From variations in the lattice parameter and the refractive index, the electrical resistivity decrease is addressed to an increase in the density of Cu vacancies. Density functional theory (DFT) calculations supported the experimental findings. The DFT results showed that in a 6% Bi doped Cu2O cell, the formation of Cu vacancies is more favorable than in an undoped Cu2O one. Moreover, from DFT data was observed that there is an increase (decrease) of the Cu2O band gap (activation energy) for 6% Bi doping, which is consistent with the experimental results

NARCISISMO E DESONESTIDADE ACADÊMICA

O objetivo desta pesquisa consistiu em verificar se traços de personalidade narcisista influenciam a probabilidade de estudantes do curso de Ciências Contábeis apresentarem comportamentos considerados desonestos no âmbito acadêmico. A amostra do estudo foi composta por 201 estudantes matriculados em três Instituições de Ensino Superior: duas públicas, uma localizada no estado de Minas Gerais e a outra no Paraná e uma particular, localizada na Bahia. Em relação aos procedimentos de coleta de dados, optou-se pela aplicação de um questionário aos estudantes. As evidências empíricas apontam que os estudantes tendem, em média, a concordar com algumas assertivas do instrumento de pesquisa que remetem a características de indivíduos narcisistas, tais como: obstinação em busca de seus objetivos; busca incansável pelo sucesso; preferência por produções individuais; dificuldades em expressar sentimentos que envolvam conflitos e sofrimentos; sentimento de culpa quando não atingem seus ideais; preocupação exacerbada com o corpo; necessidade de impressionar bem os outros; sentimento de incômodo quando precisam de alguém; busca desenfreada pelo prazer; dentre outras. Porém, verificou-se que tais tendências narcisistas não exercem influência sobre a probabilidade de os estudantes apresentarem comportamentos considerados desonestos no ambiente acadêmico. Infere-se, portanto, que na amostra analisada níveis mais elevados de narcisismo não implicam um impacto direto sobre a desonestidade acadêmica

Estudo epidemiológico do comportamento da SRAG pelo vírus Influenza em crianças antes e após a pandemia do Covid-19 no Brasil: Epidemiological study of SARS by Influenza behavior in pediatrics before and after Covid-19 pandemic in Brazil

O Myxovirus influenzae tipo A subtipo H1N1, vírus causador da Gripe Influenza, apresenta grande relevância clínica dada sua maior capacidade de causar epidemias. Sua principal complicação, a Síndrome Respiratória Aguda Grave (SRAG), deve ser cuidadosamente monitorada pelos profissionais da saúde dada a sua alta taxa de mortalidade. O SARS-Cov-2, agente causador da COVID-19, também possui a SRAG como uma de suas principais complicações, o que levou os primeiros casos de COVID-19 a serem tratados como uma possível cepa mutante do Vírus Influenza. Portanto, a compreensão da realidade epidemiológica da SRAG no Brasil é de fundamental importância para o entendimento da exposição a ambos os vírus atualmente circulantes e que possuem essa síndrome como agravo comum. Logo, este trabalho tem por objetivo analisar o comportamento epidemiológico dos casos de SRAG decorrentes de Influenza nas faixas etárias da população pediátrica, em âmbito nacional, antes e após a pandemia. Foram coletados na base de dados da Secretaria de Vigilância em Saúde os números absolutos de hospitalizações por SRAG causada por Influenza para as faixas etárias de 0 a 2, 3 a 5, 6 a 9 e 10 a 19, para cada um dos quatro anos referidos. Para a análise da normalidade, foi utilizado o teste de Shapiro-Wilk e, para comparação entre os grupos estudados foi o Kruskal-Wallis para dados não paramétricos. Todos os resultados obtidos através do teste Shapiro-Wilk apresentaram p ≤ 0.05. Os resultados do teste de o Kruskal-Wallis demonstram que em todas as faixas etárias estabelecidas neste estudo houve diferença significativa nos casos notificados de SRAG por Influenza nos anos de 2020 e 2021, quando comparados aos anos de 2018 e 2019, sendo a faixa etária de 0 a 2 a que apresenta o padrão de maior risco de acometimento por SRAG

Seborrheic Keratoses as the First Sign of Bladder Carcinoma: Case Report of Leser-Trélat Sign in a Rare Association with Urinary Tract Cancer

Introduction. Skin disorders can be the first manifestation of occult diseases. The recognition of typical paraneoplastic dermatoses may anticipate the cancer diagnosis and improve its prognosis. Although rarely observed, the sudden appearance and/or rapid increase in number and size of seborrheic keratoses can be associated with malignant neoplasms, known as the sign of Leser-Trélat. The aim of this report is to unveil a case of a patient whose recently erupted seborrheic keratoses led to investigation and consequent diagnosis of bladder cancer. Case Presentation. A 67-year-old man was admitted to the intensive care unit due to an exacerbation of chronic obstructive pulmonary disease (COPD). On physical examination, multiple seborrheic keratoses on the back of the hands, elbows, and trunk were observed; the patient had a 4-month history of these lesions yet was asymptomatic. The possibility of Leser-Trélat syndrome justified the investigation for neoplasia, and a bladder carcinoma was detected by CT-scan. The patient denied previous hematuria or any other related symptoms. Many of the lesions regressed during oncologic treatment. Conclusion. Despite the critics on the validity of the sign of Leser-Trélat, our patient fulfills the description of the disease, though urinary malignancy is a rare association. That corroborates the need of further investigation when there is a possibility of paraneoplastic manifestation

Bone Radiographic Changes in Slaughter Buffalos with Low Body Condition Index

Background: The largest buffalo herd in Brazil is located on the Island of Marajó, in the State of Pará, northern Brazil. The pastures of the Island of Marajó consist of low quality graminaceous plants, which are generally poor in protein and mineral content. Unbalanced diets associated with low quality pastures are responsible for latent, sub-clinical diseases and metabolic disorders in bovines which affect bone health, especially in periods such as pregnancy and lactation. The purpose of this study was to point out and to describe the radiographic bone changes of buffalos with low body index bred in extensive system and intended for slaughter on the Island of Marajó, Brazil.Materials, Methods & Results: Radiographic examinations of anatomical pieces were obtained from 34 animals of buffalo species, with no distinction of gender, age, or breed. The animals were selected among those that were in the stockyard waiting for slaughtering for the obtainment of the anatomical pieces. For this selection, low physical condition was considered, which mainly included individuals with body condition indexes (ICC) of 1 and 2, on a scale of 1 to 5. From this selection, 98 anatomical pieces were obtained, which included: 28 sets of ribs, 20 femurs, 26 metacarpus, 7 mandibles, 3 radius and ulnas, 4 sets of vertebrae, 4 sets of metacarpus and phalanges, 1 tarsus and 1 set of tarsus and metatarsus. All the pieces were separated, identified, packed in plastic bag and forwarded to the radiographic study. At least one radiographic projection was obtained of each anatomical piece. These were identified, manually processed and stored for subsequent assessment. A single observer, in order to identify and to describe the bone radiographic changes, subjectively performed the radiographic assessment.Discussion: Bone changes were remarkable and in animals of this study, reinforcing the nutritional aspect as being of great importance for the perfect mineral homeostasis and for the osteoarticular system maintenance. Consistent radiographic findings with osteopenia are most often related to nutritional disorders that affect bone metabolism, mainly involving the homeostasis of calcium (Ca) and phosphorus (P). The nutritional hyperparathyroidism, more commonly reported in dogs, cats and exotic animals is a common example of these affections, in which the bone radiopacity reduction is the most evident radiographic aspect. Copper (Cu) deficiency has been correlated with osteochondrosis, epiphyseal fracture of the femoral head and degenerative arthropathy of the hip joint, and erosion of the articular cartilage in a deer (Cervu selaphus). Degenerative arthropathy through radiographs was also found in this study. From the bone radiographic analysis, it is concluded that the osteodystrophic diseases of buffalos raised in pasture system on the Island of Marajó, Pará, Brazil, present a variety of pathological conditions and the most commonly found were: osteoporosis characterized at the radiographic examination for the bone decreased radiopacity, change in bone trabeculae (medullary expansion) and cortical thinning, followed by pathological fractures with high incidence in the ribs. The low body condition, the underdevelopment and cachexia states of the animals in this study indicate the lack of an appropriate prophylactic conduct and a proper feed management. Therefore, the low reserves of P and Cu in the organism may have contributed to the osteoporotic process and, possibly, also to the protein-energy deficit, leading to secondary bone changes and causing a lack of productivity in the herd
