Knowledge Economy in Brazil: Analysis of Sectoral Concentration and Production by Region

The research presented in this article investigates and analyzes the concentration of knowledge production in Brazil, in the context of a public policy, at postgraduate level, by using the spectral methods grounded on the LQ (location quotient) and CI (concentration index) indicators, in three dimensions, from 2013 to 2018. The dimensions are economics, geography, and time. Economics is represented by Fields and Major Fields of knowledge production. Geography corresponds to the regions identified by each Federation unit (FU). Time is a chronological unit of the timeline in which knowledge is produced. The research then evaluates knowledge concentration in the income performance of the families by FU. The results are robust and indicate significant evidence that sectorial knowledge production in Brazil is regionally unequal and impacts on family incomes, but those family incomes evolve regardless of the knowledge concentration level produced. The research contributions are relevant to assist public policy regulators and monitoring managers, as well as to encourage future discoveries in regional economics applications.
Interactive comment on “Impact of absorbing and non-absorbing aerosols on radiation and low-level clouds over the Southeast Atlantic from co-located satellite observations” by

The study examines the impacts of smoke and other aerosols species on the low-level clouds over the southeast Atlantic. The paper’s main goal is to characterize the effects of aerosol loading, aerosol types, and the mid-tropospheric relative humidity on the thermodynamical profile, radiative heating rates, and the cloud-top radiative cooling. To do so, the study used aerosol and cloud retrievals from CALIPSO and CloudSat as well as MERRA-2-based meteorological variables obtained as part of CALIPSO and ERA5 reanalysis dataset (see Table 1). The study focused on the area between 10 to 18◦S and 2 to 10◦E, and between June and October 2007 and 2010. According to
Evaluation of the effectiveness of Camellia sinensis on fat peroxidation and Ox-LDL in rats

It has been believed that Green tea (GT) drinking has an antioxidant property and have beneficial effects in the treatment of some disease. However, few findings were found on the impact of GT on oxidative stress. In this study, the protective effect of green tea against oxidative stress caused by hydrogen peroxide in rats was evaluated. For this purpose, research groups in four weeks include, the control (con) and five groups supplemented (G1) with 10g GT, (G2) with 20g GT, (P) with 1% H2O2, (GP1) with 1% H2O2 with 10g GT and (GP2) with 1% H2O2 with 20g GT. The results of the administration of GT in H2O2 rats on serum biochemical parameters such as lipid profile, Malondialdehyde (MDA) and oxidized lowdensity lipoprotein (OX-LDL) were estimated. The findings obtained from this research revealed that the usage of GT lowered the level of cholesterol (CHO), triglyceride (TG), lowdensity lipoprotein (LDL), coronary risk index (CRI), MDA Ox-LDL concentrations; it also demonstrated Increases in high-density lipoprotein and very-low-density lipoprotein (VLDL) compared to rats supplied with H2O2 (P) group, the baseline lipid profiles and tea consumptions with or without H2O2 were equivalent across the con and GT treated groups. The usage of GT found to be advantageous in lowering Ox-LDL and lipid peroxidationin rats. These findings validate the traditional use of GT to protect against lipid peroxidation and atherosclerosis.

HUMAN ACTIVITY RECOGNITION USING PSEUDO FREE-LIVING DATA By JOSHUA SHANNON

Human activity recognition involves the learning and classification of various activities performed in daily life. However, most research has focused on using carefully obtained data collected in a supervised, laboratory setting that is far from representative of data collected in real-world conditions. Therefore, this project has investigated several machine learning models and studied the hyperparameters involved in human activity recognition on a pseudo free-living dataset collected at the University of Georgia. On this data set, we found that standard, flat models outperformed hierarchical metaclassifiers with MLPs and SVMs achieving 64.62% and 63.95 percent accuracy on classifying 7 different activities. Ensemble models achieved only marginally better results. A window size of 10 seconds was found to be ideal for this dataset, and participant pre-training was revealed to be a promising method for improving classification accuracy. It was observed that activities on an incline, such as ascending and descending stairs, proved the most difficult to classify. Excluding this class improved accuracy to 80%, while folding it into the “walking comfortably” class further increased accuracy to 85.9%.

The Prevalence of Functional Disability and Associated Factors among Older People Attending Primary Health-care Centers in Riyadh City

BACKGROUND: The burden of disability among the older population is increasing as older people grow with significant social and economic negative impacts. AIM: This study examines functional disability and its associated risk factors among older Saudi citizens attending primary health-care centers (PHCCs) in Riyadh city. METHODS: This descriptive cross-sectional study was carried out on 504 older Saudi citizens aged ≥60 years who attended a PHCC in Riyadh city between December 2019 and May 2020. Interviewer-administered questionnaire was used to assessing the disability in activities of daily living (ADL) and instrumental activities of daily living (IADL) using the Katz Index and Lawton scale. RESULTS: The prevalence of ADL and IADL disability among participants was 24.6% and 58.5%, respectively. Smoking (p = 0.019), dyslipidemia (p = 0.018), rheumatoid arthritis (p = 0.028), history of falls (p = 0.014), and an emergency visit (p = 0.049) were risk factors associated with ADL disability. Predictors of IADL disability were advanced age (p = 0.004), being female (p = 0.029), and the need for a caregiver (p = 0.000). The need for homecare was positively associated with ADL dependency (p = 0.008) and IADL dependency (p = 0.003). Furthermore, regular physical activity was a protective factor against ADL functional disabilities (p = 0.002) and IADL functional disabilities (p = 0.000). CONCLUSION: This study found a high prevalence of ADL and IADL disability among elderly Saudis. Disability was associated with several sociodemographic and health status factors. The findings of this study highlight the priority of effective and targeted preventive interventions for disability.
Biochemical and Biological Influences of Sub-Lethal Concentrations of Emamectin Benzoate and Certain IGR Insecticides against Spodoptera littoralis (Lepidoptera: Noctuidae)

Toxicity and sub-lethal effects of Emamectin benzoate and IGR ‘s (lufenuron flufenoxuron) were evaluated against the 2 instar larvae of cotton leafworm, Spodopter alittoralis. The biochemical influences of these agrochemicals with the polyphenol oxidase (PPO) of the treated larvae were investigated (invivo). Emamectin benzoate (LC50 = 0.007 mg L ) was approximately 34 and 83 times more toxic than lufenuron (LC50 = 0.24 mg L ) and flufenoxuron (LC50 = 0.58 mg L ), respectively. Lufenuron was approximately 2 times more toxic than flufenoxuron. The 2 instar larvae treated with the sublethal concentrations (LC10 and LC25) of emamectin benzoate, lufenuron or flufenoxuron showed significant (P < 0.05) reduce of larval body weights, pupation%, pupal mean weight and adult emergence%. While the average time of the pupation for the larvae that given concentrations equivalent to the LC10 and LC25 of lufenuron and flufenoxuron, were significantly longer than the untreated larvae. On the other hand larval duration for the larvae that given concentrations equivalent to the LC10 and LC25 of emamectin benzoate did not differ significantly compared with the untreated larvae. The fecundity and fertility were strongly reduced in all insecticide treatments compared with check untreated. The PPO activity was partially decreased in the treated larvae (with all insecticide treatments) in a concentration dependent manner. These results suggest that, sublethal concentrations of emamectin benzoate, lufenuron and flufenoxuron may reduce the population growth of S. littoralis by affecting its development and reproduction.
Influence of match location, competitive level and match outcome on running performance in professional soccer players

Introduction: The context of soccer matches (e.g., match location, competitive level, match outcome) can impact the players’ physical performance. Aim: To investigate the effects of the match location, competitive level and match outcome on match running performance in professional Brazilian players. Methods: The performance data were monitored in 16 male soccer players of the same team during the following championships: 1st Division of the Capixaba Championship 2020 (n = 8 matches; n = 64 individual observations) and; 1st and 2nd Phases of the Brazil Cup 2020 (n = 2 matches; n = 16 individual observations). The match running performance was calculated using Global Positioning System: 1) total distance covered; 2) total distance covered in high-intensity; 3) total distance covered in high-acceleration. The t-test for independent measurements was used to compare the home vs away, national vs. state, and win vs. loss matches. The magnitude of the effects (ES) was calculated using Cohen’s “d”. Multiple linear regression was used to estimate the relative contribution of independent variables to the variation of dependent variables. Results: The matches played at “home” resulted in greater physical demands compared to “away” (p < 0,001−0,01, ES = moderate−very large). Matches at the national level required greater running demands than matches at the state level (p < 0,001, ES = very large). Winning matches were more physically demanding compared to losing matches (p < 0,001−0,002, ES = very large). Conclusion: Coaches can use this information to prescribe training sessions that are more representative of the match context.
The Effects of Pentoxifylline on Memory in Male Rats Treated with Zinc Oxide NPs

Background: Zinc oxide Nanoparticles (NPs) present irreversible effects on the nervous system, memory, and learning. Objective: The current study aimed to investigate the effects of pentoxifylline on memory impairments, CA1 hippocampal pyramidal cells, and blood serum antioxidant enzymes in male rats treated with zinc oxide NPs. Methods: Male Wistar rats were divided into the control, zinc oxide NPs (1.25 mg/kg), pentoxifylline (50 mg/kg), and pentoxifylline with zinc oxide NPs groups. In all study groups, saline, zinc oxide NPs, and pentoxifylline were intraperitoneally injected 30 minutes before training. In the co-treatment group, pentoxifylline was injected one hour before injecting Zno NPs. After performing the behavioral test, the tested animals’ brains were fixed and the number of healthy neurons in the CA1 region of the hippocampus was counted. In all research groups, malondialdehyde levels, total antioxidant power, superoxide dismutase levels, and glutathione peroxidase in blood serum were measured. Results: Zinc oxide nanoparticles decreased memory and the number of healthy neurons in the CA1 region of the hippocampus and increased oxidative stress in blood serum, compared to the controls. In the co-treatment group, using pentoxifylline improved the above-mentioned factors and reached the level of the control group. Pentoxifylline alone presented no significant effect on the aforementioned characteristics, compared to the control group. Conclusion: ZnO NPs may decrease memory retrieval and cause cell death in the pyramidal neurons of the CA1 region of the hippocampus by increasing oxidative stress. Pentoxifylline, as a potent antioxidant, can prevent the harmful effects of ZnO NPs.
The mitochondrial phylogeography of the Crimean endemic lizard Darevskia lindholmi (Sauria, Lacertidae): Hidden diversity in an isolated mountain system

Abstract The Lindholm rock lizard, Darevskia lindholmi, is the only member of the genus Darevskia whose range is restricted solely to Europe, representing a local endemism found only in the Crimean Mountains. In our study, we investigated the cytochrome b gene (mtDNA) of 101 D. lindholmi sequences from 65 Crimean localities, representing its entire range. We found that D. lindholmi is highly genetically structured, and its range is divided into populations belonging to three mitochondrial lineages. The Lindholm rock lizard populations inhabiting the middle part of the Crimean Mountains (further referred to as the Central lineage) are sharply differentiated from the other two lineages (the Common and the Southwestern lineages), which are present in most of the species range. The genetic distance between the Central lineage and the other two taken together is 4.6%, according to our results, suggesting that the divergence occurred during the Early Pleistocene. The narrowly distributed Southwestern lineage and the widespread Common lineage, on the other hand, are differentiated by 1%. Field observations on the representatives of the main evolutionary groups show that their ecology is also different: the Central lineage is a mesophilic and cold-resistant form, while the other two closely related lineages are more xerophilic and thermophilic. Results of the potential ranges modeling and ecological niche analysis confirm that the genetic lineages occupy different niches of the Crimea. Furthermore, the area of inhabitation of the Central lineage splits the western and eastern parts of the Common lineage range, while the Southwestern lineage is restricted along the coast of the southwestern coast of the peninsula. The long-term co-existence of deeply divergent sister mitochondrial lineages in a relatively small (circa 7,000 km2) isolated mountain system serves as a mesocosm for understanding the speciation process. Our data suggest that the Central lineage warrants further taxonomic investigation.

The Customer As A Productive Resource: A Pilot Study and Strategic Implications

Service delivery is an interactive process in which customers are often vitalparticipants, with the level of participation varying among individual consumers.Using a service setting (i.e., YMCA), a pilot study examines differences inorganizational socialization of customers and outcomes experienced by customersfor three levels of customer participation. The findings indicate that thereare significant differences in the (a) degree of organizational socializationacross customers and (b) perceptions of service quality for the different levels ofcustomer participation. Specifically, organizational socialization and perceptionsof service quality increase as customers become more active participantsin service delivery. Strategic implications are considered.
The correlation between perception and production of English sentence stress by Chinese EFL learners

A wealth of research has examined the correlation between perception and production of L2 segmental contrasts. A moderate correlation in vowel perception and production has been detected in numerous studies [1], [2],[3], while there are other researchers that have failed to find definitive evidence of this relationship and argued that good perception does not necessarily guarantee good production [4], [5], [6]. However, few have investigated the relationship between the two variables at the suprasegmental level, especially regarding sentence stress for Chinese EFL learners. Therefore, the current research intends to explore whether a correlation exists between Chinese EFL learners’ perception and production of English sentence stress. Two research questions were formed in the study. RQ1. Is there a correlation between perception and production of English sentence stress by Chinese EFL learners? RQ2: Does the type of production tasks influence native listeners’ judgement towards Chinese EFL learners’ accent in oral production?
EFFECT OF CO-CREATION ON CUSTOMER EXPERIENCE, TRUST AND BRAND LOYALTY

Emerging economies are moving towards experience economies. Be it products or services, it is experience that matters most to the customers. Products have to be wrapped in the flashy wrapping of experience for the customers to prefer them. Earlier businesses used to function like traditional theatre, with organizations working on clearly defined roles and customers watching passively on paid tickets. But now, businesses seem to be like experiential theatres where everyone and anyone can take part. Customers don’t want to be passive watchers but like to be active participants. The paper proposes a framework for effective customer participation in service industry. The purpose of this paper is to study the effect of customer participation through co-creation on customer experience, trust and brand loyalty.
The Physical Activity Class Satisfaction Questionnaire (PACSQ) in Greek educational context: Psychometric properties

Background: The Greek bibliography does not provide researchers with a credible measurement instrument that can estimate satisfaction as a multi-dimensional concept, in the frame of a physical education lesson. Objective: The main aim of this study was to cross-validate the Greek version of the Physical Activity Class Satisfaction Questionnaire (PACSQ) in a Greek educational context. The internal consistency of the PACSQ was also examined as well as the levels of satisfaction, gender, and grade of studies as factors that differentiate lesson satisfaction from lesson attendance. Methods: A total of 459 elementary school students (220 boys and 239 girls) aged between 11 and 12 years, across the country joined in the study. The Greek version of PACSQ was used. The statistical analysis included descriptive analysis, confirmatory factor analysis, reliability analysis and discriminant and convergent validity, and one-way multivariate analysis of variance. Results: The results of the confirmatory factor analysis demonstrated that the hypothesized model produced a significant χ2 (3311.55), normed fit index (.95) and comparative fit index (.96). The root mean square error of approximation (.62) was also considered to assess the degree of fit of the model. Composite reliability (≥ .879) and variance extracted (≥ .586) of all dimensions of the PACSQ demonstrated an acceptable reliability coefficient. Conclusions: From the analysis of the results, we came to the following conclusions. The PACSQ constitutes an instrument credible enough to measure the satisfaction of elementary school male and female students. Students seem to be quite satisfied by the cognitive process. Gender is a differentiation factor only as far as Normative Success is concerned. Students in the 6th grade (12 years old) appear to be more satisfied by their participatiοn in a physical education lesson.
Natural Resources for Human Health

This study evaluates the influence of mixed algal extract (Chlorellavulgaris, Euglenaviridis and Spirulinaplatensis) on common carp CyprinusCarpio, which infected infect with bacterial pathogen Aeromonas hydrophila. C. carpio was administered intraperitoneally with various doses such as methanol extract (0, 0,1, 1, 10 and 100 mg/kg). The immunological parameters of fish blood and serum samples (Neutrophil activity, Lysozyme activity, Serum myeloperoxidase intensity, Serum bactericidal activity, and Serum antiprotease activity) were investigated at 7, 14, 21, and 28 days of post-immunization. Fish had been tested by virulent A. hydrophila for 30 days after treatment and 14 days after infection were identified with mortalities. The findings showed that neutrophil levels, lysozyme activity, serum bactericidal activity, myeloperoxidase activity, and serum antiprotease activity significantly enhanced (p<0.05) compared to untreated control. Mixed dietary algae at 1 and 10 mg/kg levels demonstrated slightly (p<0.05) higher relative percentage survival (90 percent) than control againstA. hydrophila disease infection. Results indicated that mixed algal extract in C. carpio positively impacts nonspecific immune parameters and boosts disease tolerance to A. hydrophila infections.
Effect of Plant density and Fertilizer Application Rates on Growth, Fruit Yield and Quality of Tomato (Solanum lycopersicum L.) in Greenhouse Condition

Plant density and fertilization are key practices for improving the fruit quality and yield of vegetables grown in greenhouses. The experiment was performed to investigate the effects of density and fertilization on the fruit yield and quality, economic efficiency of Solanum lycopersicum L. at Duc Trong district of Lam Dong province. The density (50,000; 33,000; 25.000 plants ha-1) and the fertilizer rates (240N – 100P2O5 – 275K2O; 300N – 125P2O5 – 344K2O; 360N – 150P2O5 – 413K2O kg and 420N – 175P2O5 – 482K2O kg ha-1) were studied in a completely randomised split plot design with three blocks. The fertilizer rate (420N – 175P2O5 – 482K2O kg ha-1) was produced the highest height (562.39 cm), fruit setting rate (69.87%), number of fruit per plant (95.65 fruits), average fruit weight (106.37 g), fruit yield (441.11 tons ha-1) and marketable fruit yield (204.31 tons ha-1). The density (25,000 plants ha-1) gave the highest fruit setting rate (75.35%), number of fruit per plant (94.84 fruits), average fruit weight (113.24 g), individual fruit yield (10.02 kg per plant) and fruit yield (501.17 tons ha-1). The combination of density (25,000 plants ha-1) and fertilizer rate (420N – 175P2O5 – 482K2O kg ha-1) have the highest fruit yield (613.5 tons ha-1), marketable fruit yield (223.91 tons ha-1) and rate of return (2.44). In addition, this combination was the best density and fertilizer level management strategy for greenhouse-grown Lahay 334 tomato cultivar in Lam Dong province, Vietnam.
