Ambulance diversion has a significant impact on patient care outcomes. Self-harm behavior in particular is associated with difficulty in hospital acceptance. This is a retrospective observational study using the Japanese ambulance dispatch data in 2015. This study aims to determine if high-level emergency care centers and hospitals with both medical/surgical and psychiatric inpatient beds are associated with a decreased rate of difficulty in hospital acceptance and shorter prehospital transfer times for patients seeking medical care after self-harm behavior using 2015 Japanese ambulance dispatch database. Multivariable analyses were performed for difficulty in hospital acceptance and prehospital transfer time. Covariates such as age, gender, the population density, time, and severity, were included in the analysis, in addition to the presence of high-level emergency care centers and hospitals with both medical/surgical and psychiatric inpatient beds in the city. There was an association between decreased difficulty in hospital acceptance and the presence of high-level emergency care centers (Odds ratio 0.62, 95% Confidence Interval 0.55 to 0.70, P < 0.01) and hospitals with both medical/surgical and psychiatric inpatient beds (OR = 0.49, 95%CI, 0.37 to 0.65, P < 0.01). There was significant reduction in prehospital transfer time in the city with high-level emergency care centers (4.21 min, 95%CI 3.53 to 4.89, P < 0.01) and hospitals with medical/surgical and psychiatric inpatient beds (3.46 min, 95%CI 2.15 to 4.77, P < 0.01). High-level emergency care centers and hospitals with both medical/surgical and psychiatric inpatient beds were associated with significant decrease in difficulty in hospital acceptance and shorter prehospital transfer time.

Published: July 2021

Here, we describe a novel bacterial strain from marine sediment, designated T37T, which was isolated from the marine sediment of Xiaoshi Island, PR China. Growth of strain T37T occurs at 15–40 ℃ (optimum, 37 ℃), pH 6.0–9.0 (optimum, 7.5), and in the presence of 0.5–5.5 % (w/v) NaCl (optimum, 1.5 %). Characteristic phenotypic traits of the novel strain include MK-9 as the major menaquinone. The major fatty acids identified were iso-C14:0 and C16:1 ω9c. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, and phosphoglycolipids were the major cellular polar lipids. The G + C content of genomic DNA was 58.4 mol%. Unusual outer membrane features deduced from the analysis of cell morphology could have formed an enlarged periplasmic space putatively used for the digestion of macromolecules. Phylogenetic analyses based on 16S rRNA genes and the genome indicated that strain T37T represents a novel species and genus affiliated with a distinct family level lineage of the verrucomicrobial subdivision 1. Our polyphasic taxonomy approach places the novel strain in a new family within the class Verrucomicrobiae, for which the name Sulfuriroseicoccaceae fam. nov. is proposed. Strain T37T (= KCTC 72799T = MCCC 1H00391T) is the type strain, for which the name Sulfuriroseicoccus oceanibius gen. nov., sp. nov. is proposed.
The Role of Chance in Individual Sports: an Agent-Based Approach for Fencing Tournaments

Published: July 2021

It is a widespread belief that success is mainly due to innate qualities, rather than to external forces. This is particularly true in sport competitions, where individual talent is considered the only ingredient in order to reach success. In this study, we propose to explore the relative weight of talent and luck in individual sports through agent-based models. In particular, we chose fencing as case study, that is a combat sport involving a weapon. Fencing competitions are structured as direct elimination tournaments, where randomness is explicitly present in some rules. Our dataset covers the last decade of international events and consists of both single competition results and annual rankings for male and female fencers under 20 years old (Junior category). We show that our agent-based approach, calibrated on the dataset and parametrized by just one free variable a describing the importance of talent in competitions (a = 1 indicates the ideal scenario where only talent matters, a = 0 the complete random one) is able to reproduce the main stylized facts observed in real data, both at the level of single fencing tournaments and of entire careers of a given community of fencers. We find that simulations approximate very well the real data when talent weights slightly more than luck, i.e. when a is around 0.55 for Junior Men, or even slightly less than luck, i.e. when a = 0.45 for Junior Women. We conclude that the role of chance in fencing is highly underestimated even if probably it represents an extreme case for individual sports. Our results shed light on the importance of external factors in both athletes’ results in single tournaments and in their entire career, making even more unfair the “winner-takes-all” disparities in remuneration.

Background: Family planning is a low-cost, high-impact public health and development strategy to improve child and maternal health. However, there is a lack of evidence on modern contraceptive use and determinants in sub-Saharan Africa. Hence, this study was aimed at determining the pooled prevalence and determinants of modern contraceptive utilization in Sub-Saharan Africa. Methods: Thirty-six sub-Saharan African countries' demographic and health survey (DHS) data were used for pooled analysis. A total weighted sample of 322,525 married women were included. Cross tabulations and summary statistics were done using STATA version 14 software. The pooled prevalence of modern contraceptive utilization with a 95% Confidence Interval (CI) was reported. Four models were fitted to select the best-fitted model using Likelihood Ratio (LLR) and Deviance test. Finally, the model with the highest LLR and the smallest deviance was selected as a best fitted model. Results: The pooled estimate of modern contraception use in sub–Saharan African countries was 18.36% [95% CI: 18.24, 18.48], with highest in Lesotho (59.79%) and the lowest in Chad (5.04%). The odds of modern contraception utilization among women living in East Africa was (AOR=1.47 (1.40, 1.54)), urban (AOR=1.18 (1.14, 1.24)), women primary and secondary and above educational level (AOR=1.49 (1.44, 1.55)), and (AOR=1.66 (1.58, 1.74)), respectively. Moreover, husband primary (AOR=1.38 (1.33, 1.42)), middle (AOR=1.17, (1.14, 1.21)), rich wealth status (AOR=1.29 (1.25, 1.34)), media exposure (AOR=1.25 (1.22, 1.29)), and postnatal care (PNC) utilization (AOR=1.25 (1.22, 1.29)) had higher odds of modern contraceptive utilization compared with their counter parts. Furthermore, deliver at health facility (AOR=1.74 (1.69, 1.79)) and birth order 2-4 (AOR=1.36 (1.31, 1.41)) had higher odds of modern contraceptive utilization. On the otherhand, women living in Central (AOR=0.23 (0.22, 0.24)), Western regions (AOR=0.46 (0.40, 0.54)), women decided with husband (AOR=0.90 (0.87, 0.93)), and husband alone (AOR=0.73 (0.71, 0.75)) were decreased the odds of modern contraceptive utilization. Conclusion: The uptake of modern contraception in sub-Saharan Africa is low. Modern contraceptive utilization is affected by different factors. More attention need to be given to rural residents, illiterate women, and communities with low wealth status.

Published: July 2021

Advanced oxidative processes are widely used in the degradation of organic compounds. The degradation and mineralization of the PNF was evaluated by means of an experimental factorial design, using photolysis (UV) and photo-peroxidation (UV/H2O2). With the results optimized, degradation kinetics was performed and the experimental data adjusted to mathematical models. In the UV system, it was possible to degrade just over 65% and mineralize 15% over 7 h of reaction; however, with the addition of the oxidizing agent H2O2, it was possible to obtain 100% removal of the contaminant, suggesting that there was no formation of intermediate compounds. Kinetics results fitting the first order model and the velocity constants revealed that degradation is extremely faster in the UV/H2O2 system (k1,UV/H2O2 = 0.0580 min− 1 > k1,UV = 0.0018 min− 1).
Consumer Attitude Toward Product Placement: A Descriptive Study Between Bangladeshi & Indian Media Program
Authors: Karmakar Anima , Nur-Al-Ahad Md. , Hyder Tanvir
Published: July 2021

The aim of this study is to investigate Bangladeshi viewers’ attitudes towards product placement activities. Here product placement indicates a paid form of non-traditional advertisement where products or brand names are intentionally present along with the programs. Consumers’ purchase decisions relate to how they know the brand name, and traditional marketing activities failed several times to hit the customer’s black box. People are fascinated by an innovative way of product representation, a tough and challenging task for marketers. Embedded marketing or Product placement helps both viewers and marketers to build a bridge for communication. In Bangladesh, people are less conscious about their local products as well as their media programs. Media and marketing relate inextricably with each other. The study has been conducted in two aspects to investigate the consumer attitude towards product placement. The first one is a comparative analysis of several product placements between Bangladeshi and the Indian media program. The second one is devolving and analyzing questionnaires to determine the Bangladeshi viewers’ scenario about embedded marketing. The logic behind choosing the Indian tv program for comparison is that Bangladeshi viewers are habituated with the Indian program. From 121 respondents, this study tries to forecast the viewers’ attitude toward product placement. Comparing Bangladeshi and Indian movies, dramas, and reality shows, the study expresses that Bangladeshi channel set minimal concern about embedded marketing. An online survey portrays a viewer’s preference level and thinking pattern about their media programs. Proper representation of programs such as an exciting story from movies and drama, a reality show with more customer engagement, less repetition of the same news, more consciousness about irrelevant talk shows, proper timing of the advertisement can help to back the viewers to their media that allows marketers to communicate with their target customers. This study has been conducted with limited sample size. Further research may be conducted about this study with large sample size and may compare with other countries.

This qualitative descriptive study explored what community college administrators and faculty described as being effective recruitment and retention methods for faculty at community colleges in the Northeastern United States. This study answered two research questions: what recruitment methods do administrators and American faculty at community colleges describe as being effective in the recruitment of American faculty? Also, what retention methods do administrators and American faculty at community colleges describe as being effective in the retention of American faculty? The researcher applied critical race theory to form a framework for best practices in recruiting and retaining American faculty. Data were obtained by interviewing six American faculty and surveying seven community college administrators employed at Massachusetts community colleges who were selected using purposive sampling and community college online staff directories. Using MAXQDA data analysis software, the researcher initiated data analysis using thematic analysis. Data were organized and analyzed to identify codes, categories, and themes. Data analysis resulted in six themes: hiring processes, faculty diversity, recruitment strategies, work environment, student and faculty relationships, and retention strategies. The findings of this study can benefit community college personnel by recommending recruitment and retention strategies to effectively recruit and retain American faculty. There was limited research and data available related to the recruitment and retention of African American male faculty at community colleges. The faculty and administrator participants of this study provided rich data on effective recruitment and retention methods for African American male faculty at community colleges. The critical race theory theoretical framework was summarized. Theoretical and practical implications emerged. Based on the data and new insights, implications for future research were discussed.

With the changing paradigm of the world and highly competitive business environments, organizations are encountered different challenges. This paper investigates the relationship between management accounting information (MAI) and decision-making and the role of cloud computing among small-medium enterprises (SMEs) in Pakistan. In particular, the focus of this paper is on the influence of MAI on decision-making. Cloud computing is a modern technology to strengthen relationships. A quantitative research design that involves printed questionnaires was used to analyze the relationships of the variables. The survey was conducted on 384 Pakistani small and medium-sized enterprises of various sectors. The study obtained 105 useable responses. Data were analyzed using Smart PLS 3.0 (Partial Least Square) to test the researcher’s hypotheses. The study found MAI to be positively related to Pakistani SMEs’ decision-making. The findings also exposed all the dimensions of MAI; namely broad scope, timeliness, aggregation and integration, to be positively related to decision-making. Additionally, the findings indicated that, as modern technology, cloud computing strengthens the relationship between MAI and decision-making. This paper contributes by helping organizations realize the importance of MAI in decision-making and how they could relate a selection of information characteristics in terms of their business environments. Moreover, it enhances the understanding of SMEs on the function of cloud computing to get better decision-making in the light of the competition in SMEs. Pakistani industry is running successfully, and small-medium enterprises have a wide gap. Small and Medium Enterprises are going successful in Pakistan, and investor can ease to decide after receiving research directions.
Intercept of Financial, Economic and Educational Transformations: Bibliometric Analysis
Authors: Novikov Vladislav
Published: July 2021

Financial, economic and educational transformations might be clarified from very different perspectives. Economic transformations are used to identify as changes in value added contribution of some branch in its formation at national level, or its productivity. Nowadays economic transformation are by far wider and more complicated process because of intensification of globalization, integration and digitalization of economic relationship over the last few decades. Financial transformations are also caused by intensification of globalization, integration and digitalization of economic relationship and might be identified through characteristics of the scale of financialization in curtain country and all over the world. Expansion of financialization and digitalization trends led to relevant changes in financial products characteristics, ways of its distribution and promotion, and general relevance of financial sector in macroeconomic stability and sustainable economic growth. Digitalization and COVID-19 pandemic also led to considerable challenges and transformation of education system. Education process are needed to be based on modern pedagogical, technological and scientific approaches. It became crucial to not only disseminate traditional knowledge and ensure of obtaining hard skills, but also make students enriched with soft skills. Traditional learning process accompanied with physical visiting of classes and writing a thesis are no more relevant, so e-learning and distance learning technologies are an integral part of educational process nowadays. It is became obvious that economic, financial and education transformation are connected somehow and converged but there is lack of researches aimed at specification of their intercept and cohesion. Therefore, this research aimed at clarification of intercept between financial, economic and education transformations has both theoretical value and might have practical implication for policymakers. It is realized using VOSviewer tool based on publications in Scopus on financial, educational and economic transformations 1990–2020. Therefore, bibliometric analysis allow concluding that there are both common and specific clusters of scientific researches on economic, financial and educational transformations. Namely, all three types of transformations are somehow dependent on health care system, environmental determinants, social aspects, etc. It can be pointed out that these transformations have common preconditions, consequences and ways of implementation. This may leads to conclusion that there are some convergence between educational, financial and economic transformations.
A Qualitative Exploratory Observational Study: An Entrepreneurship Managers’ Emotional Intelligence and Impact on the Financial Organization’s Success in the United States
Authors: Luncheon Amala , Kasztelnik Karina
Published: July 2021

This paper summarizes the arguments and counterarguments within the scientific discussion on emotional intelligence. Emotional intelligence is an essential trait for managers to possess to be effective and successful in organizations. Soft skills are becoming as crucial as making quotas. Scholarly literature lacks research on emotional intelligence and employee engagement in retail in St. Lucia. Engaged employees could stay motivated during adversity and help maintain an organization’s culture. This exploratory observational study’s primary purpose was to examine how retail store managers in St. Lucia perceived their emotional intelligence influences employee engagement. The conceptual framework that grounded the study was emotional intelligence and employee engagement from an organizational performance perspective. The data collection process included reviewing archival data. The paper presents empirical analysis results; several patterns and themes emerged from the data analysis, including emotional intelligence, controlling emotions, coaching, legacy, training, hiring well, communication, and personalized relationships. Increased emotional intelligence training emerged as useful in the St. Lucian business landscape and the Caribbean by extension. The research empirically confirms and theoretically proves that researching other sectors at varying levels may give a broader understanding of how emotional intelligence is perceived. This study’s findings may be useful to stakeholders and organizational leaders to allow developing strategies to build more emotionally intelligent and engaged organizations and positively affect social change.
Do Discounts Enhance or Degrade IPOs Valuation Performance?
Authors: Tizniti Douaa , Aasri Mohammed Rachid
Published: July 2021

In the present study, we investigate the impact of discounts on the valuation performance of initial public offerings. Review of existing literature reveals that such valuation performance lacks examination in terms of discounts as most studies focus on valuation methods. Accordingly, we examine the valuation performance of initial public offerings before and after applying discounts. Whereby, underwriters apply a deliberate discount to fair value estimate before setting the final offer price. We assess the valuation performance of initial public offerings through bias and accuracy errors as well as explainability. When valuation errors are low, the valuation performance is deemed superior. Our sample consists of 39 initial public offerings conducted on the Moroccan stock exchange between 2004 and 2018. We use publicly available prospectus to collect necessary data. Our results reveal that discounts applied to fair value estimate when setting the final offer price reduce valuation errors. Consequently, discounts enhance the valuation performance of initial public offerings. In fact, both optimistic and pessimistic final offer price are closer to market price in comparison with optimistic and pessimistic fair value estimate. We conclude that if valuations conducted by underwriters are objective, discounts serve as a qualitative valuation to supplement the quantitative one. This qualitative valuation incorporates relevant information about market circumstances with regard to initial public offerings. This indicates the superior fundamental analysis underwriters are capable of performing. However, if valuations conducted by underwriters are subjective, then underwriters deliberately overestimates fair value estimate to justify applying discounts when setting the final offer price. Nonetheless, our study reveals that discounts are more than proportional to valuation optimism. Consequently, while discounts absorb this valuation optimism, they also set a valuation pessimism. In other words, discounts avoid overpricing initial public offerings, yet they result in underpricing them. Interestingly, we discover that although optimistic fair value estimate and pessimistic final offer price have approximate valuation errors, underwriters are more comfortable underpricing initial public offerings than overpricing them.
How Do We Decide? Thought Architecture Decision Making?
Authors: Njegovanović Ana
Published: July 2021

The study of decision-making is an intellectual discipline; mathematics, sociology, psychology, economics, political science, artificial intelligence, neuroscience and physics. Conventional decision theory tells us what choice of behavior should be made if we follow certain axioms. Scientific curiosity instructs us to reconsider beyond any area in which we have defined ourselves. We design the intertwining of brain, genetics, phylogenetics, and artificial and neural networks in financial trading to find the best combinations of parameter values in financial trading, incorporating them into ANN models for stock selection and trader identification. The purpose and goal of the paper is to make financial decisions in the intertwining of the brain, genetics, phylogenetics and artificial neural networks, focusing on opening new foundations, giving insights into the foundation rock that lies beneath that soil. Science seeks basic natural laws. Mathematics seeks new theorems to build on old ones. Engineering builds systems to address human needs. The three disciplines are interdependent, but different and yet Claude Shannon simultaneously makes a central contribution to all three disciplines, this was the guiding idea of our work (finance, neuroscience, artificial intelligence).

Authors: Singh S.N.
Published: July 2021

Credit Risk management becomes major discussion issues in the financial institutions because of uncertainty related to borrower’s business. The aim of this study is to assess credit risk management tools and technique that are being used in the bank and to what extent the current performance of the bank is supported by proper credit risk management policy, procedure and strategy. The study design is descriptive. The research applies for both qualitative and quantitative research method and both primary data (questionnaire) and secondary data were collected to meet the objective of the study. 15 out of 20 total population Purposive samples were involved at Branch office using census sampling method who works on credit to get reliable and valid information about the study subject. The data was analyzed using qualitative and descriptive statistics technique and frequency table. From the findings the study concludes that the bank has well organized credit policy that counter to credit risk they are exposed to and it also conclude that the bank has good credit granting practice and uses suitable credit risk assessment tools and techniques including loan follow-up, risk identification, measuring, evaluating, monitoring and controlling mechanism. However, the study also concluded that the bank has pitfalls such as absence of training for customers which results to loan diversion, absence of credit risk model that predict the risk level of the business and the priority sectors of the bank in terms of credit facility are highly exposed to credit risk which directly contribute to the increment of NPL. Thus, it is recommended that Dashen Bank S.C should develop independent risk management policy and procedure from credit policy and procedure to overcome those problems and to take measure on the spot.
Field-induced magnetic states in geometrically frustrated SrEr2O4

Published: July 2021

We report an unusual in-field behaviour of
SrEr_22O_44
for a magnetic field applied along two high-symmetry directions, the a
and c axes. This geometrically frustrated magnet hosts two
crystallographically inequivalent Er ions, Er1 and Er2, that are both
located on triangular zigzag ladders, but only one site, Er1, forms a
long-range magnetic order at low temperatures in a zero field. We follow
the sequence of peculiar field induced states in
SrEr_22O_44
with detailed single-crystal magnetisation and neutron diffraction
experiments. On application of an external field along the
cc axis,
the long-range antiferromagnetic order of the Er1 ions is rapidly
destroyed and replaced, in fields between 2 and 5 kOe, by a state with
shorter-range correlations. The change in correlation length coincides
with a fast increase in magnetisation during the metamagnetic transition
above which a long-range order is reestablished and maintained into the
high fields. The high-field ferromagnet-like order is characterised by
significantly different magnetic moments on the two Er sites, with the
Er1 site dominating the magnetisation process. For the field applied
parallel to the a axis, in the field range of 4 to 12 kOe, the planes of
diffuse magnetic scattering observed in zero field due to the
one-dimensional correlations between the Er2 moments are replaced by
much more localised but still diffuse features corresponding to the
establishment of an up-up-down structure associated with a one-third
magnetisation plateau. Above 14 kOe, a ferromagnet-like high-field order
is induced following another phase transition.
For this direction of the field, the Er2 moments dictate the succession
of transitions while the Er1 moments remain significantly less
polarised. A complete field polarisation of both Er sites is not
achieved even at 50~kOe for either field direction, reflecting the
strongly anisotropic nature of magnetisation process in
SrEr_22O_44.

Published: July 2021

The Lower Indus reaches – Guddu and Sukkur – are among the most complicated areas in terms of reach migration. Both climate change and human activities in recent periods along with pond system operation accelerated riverine channel morphology. A GIS-based approach using multi-temporal Landsat images (1986–2020) was employed to characterize the morphometric parameters. Results showed that width of the study reaches varied from 2.1 to 12 km. The braiding index (BI) value for Guddu reach varied from 3.47 to 7.18, and BI value for Sukkur reach varied from 2.11 to 4.92. It is observed that no erosive activity of banks occurred for peak runoff value of <5,880 m3s−1. The sediment load during low flow (LF) period was estimated to be 0.715 million tons/day which comprised 77% fine sediment and 23% sand. The sediment load during high flood (HF) period was about 1.296 million tons/day. The median size (D50) of bed material during the HF period was 0.101–0.206 mm and during LF period was <0.0625 mm. The rough set theory (RST) showed that velocity, shear stress, slope, runoff, and sediment load factors are major contributors to the river shape changes. This study is a standpoint of planning flood recovery, riverine regulations, and navigation safety.

The effects of depth and climate seasonality on zooplankton, algal biomass, coliforms and Escherichia coli in a small full-scale shallow maturation pond receiving pre-treated domestic wastewater were evaluated during a tropical climatic seasonal cycle. The experiment revealed that the zooplankton community was dominated by rotifers and protozoans, and concentrations were influenced by seasonality. A negative correlation between zooplankton, and pH, dissolved oxygen, temperature and ultraviolet radiation, and chlorophyll-a and Escherichia coli were observed at all depths. The major driving forces influencing Escherichia coli were pH, dissolved oxygen, ultraviolet radiation and the zooplankton. A significant difference between Escherichia coli removal throughout the three different depths were observed. Both bacterial and zooplankton concentrations were greater closer to the bottom of the pond, therefore reinforcing the integral role of solar radiation on bacterial removal. These results give an insight on the dynamics of these groups in pond systems treating domestic wastewater, by correlating the variation of zooplankton with biotic and abiotic variables and seasonal changes in a tropical climate, where few studies have been performed on this topic.

Published: July 2021

Objetivo: A preocupação com o meio ambiente é constante e vem, gradativamente, ganhando destaque: político, acadêmico e empresarial. O tema configura-se como relevante, porque para a maioria das empresas a preocupação com o meio ambiente ainda não se transformou em práticas efetivas de gestão ambiental e muitos profissionais da contabilidade têm formação anterior a inserção da contabilidade ambiental como um novo ramo de atuação das ciências contábeis. No entanto, a educação continuada se estabelece como um meio de atualização dos profissionais em relação as mudanças e novas tendências de atuação do profissional contábil. Assim, a pesquisa se propôs analisar o nível de conhecimento dos profissionais de contabilidade de Três Lagoas (MS) sobre contabilidade ambiental, gestão e legislação ambiental.
Metodologia: A pesquisa classifica-se como quantitativa e adota como estratégia de investigação a pesquisa de levantamento de opiniões dos contadores atuantes nos escritórios de contabilidade em Três Lagoas (MS). A aplicação dos questionários seguiu o critério de acessibilidade, obtendo-se um retorno de 68 questionários respondidos. O instrumento de coleta foi construído com questões que identificam o perfil dos contadores e nível de conhecimento sobre a contabilidade ambiental, gestão e legislação ambiental. Ele é composto por 15 itens avaliados pela escala tipo Likert de seis pontos.
Resultados: Os resultados demonstram nível baixo de conhecimento dos contadores sobre contabilidade ambiental, gestão e legislação ambiental, numa média geral de 71,2%. Apenas 32,4% dos respondentes buscam atualização profissional na área ambiental por meio de eventos, palestras ou congressos e 55,9% dos respondentes não tem conhecimento sobre ferramentas de gestão ambiental.
Contribuições do Estudo: O tema demanda maior envolvimento e busca de conhecimento dos contadores, por meio dos programas de educação profissional continuada. Fica a reflexão de que a contabilidade e gestão ambiental são importantes e devem ser cada vez mais abordadas nas práticas contábeis, visto que os impactos ambientais resultam em atos e fatos contábeis, cujo gerenciamento e/ou registro precisam de um profissional em contabilidade formado e atualizado de forma adequada.
PROFUT: uma análise da estrutura de capital de times brasileiros
Authors: Maia da Rocha Erika , Ícaro Silvério de Oliveira Francisco , Queiroz Souza Valdevino Rosângela
Published: July 2021

Objetivo: A pesquisa procura verificar a relação existente entre o atendimento aos requisitos pertinentes à adesão e permanência no PROFUT e a situação econômico-financeira de clubes de futebol brasileiros listados no Ranking Nacional de Clubes (RNC).

Metodologia: O estudo foi operacionalizado pelo método dedutivo, tendo abordagem empírica, valendo-se da análise de indivíduos, fatos e consequências pesquisados. Quanto aos procedimentos adotados, a pesquisa é classificada como uma revisão bibliográfica e documental e de abordagem quantitativa. O assunto foi tratado por meio da aplicação de uma averiguação dos pontos da legislação, por meio de um checklist, e da apresentação de indicadores econômico-financeiros: endividamento, liquidez corrente, tangibilidade, tamanho e retorno sobre o patrimônio líquido.

Resultados: Dada a investigação realizada, percebeu-se que, mesmo com as atuais exigências da legislação e critérios de exigibilidade para participação no PROFUT, a adesão ao programa não garante uma melhor situação econômico-financeira, principalmente relacionado aos fatores inerentes a estrutura de capital.

Contribuições do Estudo: O trabalho contribui de forma teórica na produção de uma análise contextualizada sobre as principais pesquisas já existentes e mostra novas explicações do fato estudado com base em diferentes perspectivas. No que diz respeito à contribuição prática, partindo dos principais achados encontrados, e buscando relacionar o nível de comprometimento dos clubes analisados, que aderiram ao PROFUT, com a gestão de sua estrutura de capital, percebeu-se a não existência de uma relação direta entre a adesão a essa modalidade de financiamento e a administração das fontes de capital obtidas.

The occurrence of neoplasms in birds is still unknown, with the literature based mainly on scarce reports, in this context, data about epidemiology in specific species are almost nonexistent. Sarcomas are malignant mesenchymal origin neoplasms, which can develop from different tissues, such as adipose, cartilage, bone, among others. The occurrence of sarcomas in birds has been previously described, with different therapeutic approaches. The present report describes the clinical approach in a blue-fronted amazon (Amazona aestiva) diagnosed with a soft tissue sarcoma in the dorsal cervical region, with surgical excision associated with a metronomic chemotherapy protocol as an adjuvant. The therapeutic combination proved to be effective in controlling the disease, guaranteeing important survival, with clinical absence of side effects.

Published: July 2021

Objective:

The objective of this study was to develop and optimize a microflora-triggered
colon targeted sustained-release dosage form using Gum Ghatti (GG) and Hydroxypropyl
Methylcellulose (HPMC K100).

Methods:

GG and HPMC K100 were used to prepare microflora triggered colon targeted sustained-
release dosage form. For evaluation, two different tablets comprising metoprolol succinate
and mesalamine as an active ingredient were used with the objective of developing a platform technology
for various categories of drugs. The tablets were coated with Eudragit® L100 and Eudragit®
S100 to provide enteric coating and evaluated for hardness, thickness, friability, weight variation,
disintegration, and drug content. in vitro release studies for the prepared tablets were carried out
mimicking the physiological transit time. Further, the effects of microflora were evaluated using
rat cecal content.

Results:

The in vitro dissolution profile of coated matrix tablets showed that 86.03±0.43% of metoprolol
succinate and 80.26±0.67% of mesalamine were released at the end of 12 h. The ex vivo dissolution
profile of coated matrix tablets showed that 96.50±0.27% of metoprolol succinate and
92.58±0.39% of mesalamine were released at the end of 12 h in the presence of rat ceacal content.
The developed formulation was stable when subjected to the standard ICH stability study conditions.

Conclusion:

The result of this study showed that gum ghatti together with hydroxypropyl methylcellulose
could be successfully used for the preparation of microflora-triggered colon targeted matrix
tablets.
