Influence Of Competition Research Articles

EDUCATION AS A MAJOR CAPITAL AND THE MAIN BASIS FOR THE ECONOMIC POTENTIAL OF THE COUNTRY

Based on the works of philosophers of the ancient world and scientists of our time, the article analyzes the need for the existence of two components of its development in any country, namely human capital and financial and political opportunities. Attention is paid to the fact that intellectual potential is a set of resources that include human intelligence and creative ability, with its characteristic educational and qualification indicators. It is proved that higher education graduates are the intellectual core that forms the market of qualified specialists capable of becoming the economic potential of the country. It is shown that the rational use of this potential, in combination with other scientific achievements of society, contributes to the achievement of a new quality of economic development, raising living standards and preserving the environment for future generations. That is, the level of awareness and education of each individual is the molecule that lays the foundation for consolidating the country's competitive influence in the international market. To implement the above, the need for more active use of public administration in the educational process at all levels is determined, the expediency of applying legislative regulation of the process of interaction between higher education institutions and business structures is investigated, both for the establishment of joint projects and processes of commercialization and reform of education in different countries, including in modern Ukraine, and for achieving positive changes in strategic planning and economic development.

People or predators? Comparing habitat‐dependent effects of hunting and large carnivores on the abundance of North America's top mesocarnivore

Variation in animal abundance is shaped by scale‐dependent habitat, competition, and anthropogenic influences. Coyotes Canis latrans have dramatically increased in abundance while expanding their range over the past 100 years. Management goals typically seek to lower coyote populations to reduce their threats to humans, pets, livestock and sensitive prey. Despite their outsized ecological and social roles in the Americas, the factors affecting coyote abundance across their range remain unclear. We fit Royle–Nichols abundance models at two spatial scales in a Bayesian hierarchical framework to three years of data from 4587 camera trap sites arranged in 254 arrays across the contiguous USA to assess how habitat, large carnivores, anthropogenic development and hunting regulations affect coyote abundance. Coyote abundance was highest in southwestern USA and lowest in the northeast. Abundance responded to some factors as expected, including positive (soft mast, agriculture, grass/shrub habitat, urban–natural edge) and negative (latitude and forest cover) relationships. Colonization date had a negative relationship, suggesting coyote populations have not reached carrying capacity in recently colonized regions. Several relationships were scale‐dependent, including urban development, which was negative at local (100‐m) scales but positive at larger (5‐km) scales. Large carnivore effects were habitat‐dependent, with sometimes opposing relationships manifesting across variation in forest cover and urban development. Coyote abundance was higher where human hunting was permitted, and this relationship was strongest at local scales. These results, including a national map of coyote abundance, update ecological understanding of coyotes and can inform coyote management at local and landscape scales. These findings expand results from local studies suggesting that directly hunting coyotes does not decrease their abundance and may actually increase it. Ongoing large carnivore recoveries globally will likely affect subordinate carnivore abundance, but not in universally negative ways, and our work demonstrates how such effects can be habitat and scale dependent.

Influence of competition on motor inhibitory control: Evidence from ago/no-go task.

The present experiment examined how individuals' motor response execution and inhibition - as measured by a Go/No-Go (GNG) task - is modulated by social influence arising from competition. We found that participants in a competition group responded significantly faster to frequently occurring Go stimuli than those in a control group, while no between-group difference in accuracy was found. This indicates that competition leads participants to favor a response strategy of maximizing the speed of prepotent motor response execution without sacrificing accuracy. In addition, participants in the competition group committed significantly more errors to infrequently occurring No-Go stimuli than those in the control group. Together, these findings suggest that competition speeds up prepotent motor response execution, which comes at the cost of reduced prepotent response inhibition. Furthermore, increased errors in prepotent response inhibition due to competition correlated positively with self-reported trait competitiveness and trait motor impulsivity, identifying the link between personality traits and competition-induced attenuation of inhibition efficiency. Our signal detection analysis revealed that these behavioral effects can be attributed to a combination of a pronounced tendency to respond in general to both Go stimuli and No-Go stimuli, as evidenced by increased response bias (C), and reduced discrimination of No-Go stimuli from Go stimuli, as indexed by decreased sensitivity (d'). Our experiment offers novel insights into how motor control is modulated by engaging in competition.

Global analysis of acoustic frequency characteristics in birds.

Animal communication plays a crucial role in biology, yet the wide variability in vocalizations is not fully understood. Previous studies in birds have been limited in taxonomic and analytical breadth. Here, we analyse an extensive dataset of >140 000 recordings of vocalizations from 8450 bird species, representing nearly every avian order and family, under a structural causal model framework, to explore the influence of eco-evolutionary traits on acoustic frequency characteristics. We find that body mass, beak size, habitat associations and geography influence acoustic frequency characteristics, with varying degrees of interaction with song acquisition type. We find no evidence for the influence of vegetation density, sexual dimorphism, range size and competition on our measures of acoustic frequency characteristics. Our results, built on decades of researchers' empirical observations collected across the globe, provide a new breadth of evidence about how eco-evolutionary processes shape bird communication.

Personalization in educational gamification: Learners with different trait competitiveness benefit differently from rankings on leaderboards

Leaderboards are among the most prevalent game elements and are widely used in educational gamification. However, most research has primarily compared learning scenarios using leaderboards with those not using leaderboards, ignoring the role of specific components of leaderboards such as rankings. Given that learners’ perceptions of leaderboards depend on their rankings, this study investigated how rankings (high vs. low) and learners’ trait competitiveness (high vs. low) influence learning in educational gamification. Sixty-one high-trait-competitiveness and sixty-two low-trait-competitiveness learners were randomly assigned to either high-ranking or low-ranking conditions. The results revealed the moderating role of trait competitiveness in the relationship between leaderboard rankings and learning. Interestingly, higher rankings were more beneficial in enhancing learning motivation of learners with low trait competitiveness, while lower rankings had more positive effects on performance of those with high trait competitiveness. Additionally, negative emotions mediated the relationship between rankings and learning performance, while the mediating effect of learning motivation was only significant for learners with low trait competitiveness. The implications of these findings for the design of effective gamified learning environments based on learners’ characteristics were discussed.

Competition Plays A Moderating Role in The Impact of Liquidity Creation on Bank Capital

Introduction/Main Objectives: This study examines the moderating influence of bank competition, proxied by the Lerner index, on the impact of liquidity creation, measured using the Catfat method, on bank capital, proxied by the equity-to-total-assets ratio. Background Problems: Limited academic literature explores how competition moderates the relationship between liquidity creation and bank capital, which is essential for maintaining stability and risk absorption in the banking sector. Novelty: This study fills the gap by demonstrating that the effect of liquidity creation on bank capital depends on the level of bank competition. Research Methods: The study uses purposive sampling, covering 96 banks from 2013 to 2023, and applies panel data regression analysis with Hayes’ method. Control variables include ROA, LDR, NPL, GDP, inflation, and Bank Indonesia interest rates. Findings/Results: The results indicate that competition moderates the negative effect of liquidity creation on bank capital, weakening this impact. This suggests that competition enables banks to maintain higher capital levels. Conclusion: The study highlights the importance of competition in moderating the liquidity creation-capital relationship, with implications for bank management and regulatory policies.

Agency conflicts, product market competition and investment efficiency: new evidence from emerging market

PurposeThis study examines the influence of product market competition on investment inefficiency of Indian firms in context of agency problems. Additionally, this study also investigates whether intense competition is a substitute for or complementary to corporate governance in reducing investment inefficiency of firms.Design/methodology/approachUtilizing the residuals extracted from Biddle et al. (2009) investment model, investment inefficiency, overinvestment and underinvestment are measured for 506 non-financial Indian listed firms with 6,998 firm-year observations from 2009 to 2022. Product market competition is measured using various proxies such as the Herfindahl–Hirschman index, top-four firm concentration ratio, total number of firms in industry, industry market size, weighted average of entry costs and research and development (R&D) to sales ratio. Firms' internal governance is measured using a newly corporate governance index developed with 65 new governance stipulations. Several pooled ordinary least squares (OLS) panel regressions were estimated involving investment inefficiency of firms, product market competition, governance index and firm-specific variables. Endogeneity issues were addressed through two-stage least squares. Robustness checks were also conducted using a two-step system generalized method of moments (GMM).FindingsThe main finding of the study indicates that heightened product market competition reduces investment inefficiency, overinvestment and underinvestment among the selected Indian firms suggesting that firms facing intense competition are less prone to invest below or above optimal levels. This is primarily because in highly competitive industries, managers face greater liquidation risks, prompting more efficient capital investment decisions. The results also indicate that robust corporate governance significantly mitigates investment inefficiencies in non-competitive industries compared to competitive ones suggesting heightened competition reduces managerial slack, resulting in diminished benefits from good governance in competitive settings. Overall results indicate a substitution effect between corporate governance and competition in reducing investment inefficiency, with robustness across various empirical specifications, industry classifications and alternative competition and inefficiency measures.Practical implicationsThe evidence from this work emphasizes the pivotal roles of market competitiveness and corporate governance in shaping investment efficiency. Regulators must closely monitor monopolistic behaviors to safeguard stakeholder interests, enhance investment efficiency and foster value creation. Recognizing the positive impact of market competition, firms should prioritize initiatives to promote industrial openness and intensify competition while strengthening market mechanisms. Policymakers should consider implementing competition-centric governance policies, such as deregulation and antitrust laws, to stimulate market competition. These measures can mitigate governance-related costs and promote a competitive marketplace.Originality/valueThis study provides fresh evidence concerning the effects of product market competition on investment efficiency of Indian firms under new governance norms, an unexplored area in India as most of the existing work has primarily examined the association between competition and investment levels. To best of our knowledge, this is one of the earliest studies demonstrating the substitution effects of competitiveness and governance systems on lowering investment inefficiency suggesting a significant influence of corporate governance in non-competitive industries. Finally, this study contributes to the field of methodology by developing a new firm-specific governance index based on 65 governance indicators.

Influence of Arsenate Competition on Tungstate Sorption by Soil

The green and digital transitions toward sustainable development will drive an increased demand for critical raw materials, among which tungsten plays a crucial role in emerging sustainable technologies. Understanding the sorption processes of tungsten in soils is essential for assessing its bioavailability and potential toxicity to living organisms. In many soils, tungsten may co-exist with other contaminants, such as arsenic. Investigating the competitive sorption between these two anions helps clarify how they interact within the soil matrix. Batch experiments were conducted on three Mediterranean soils to evaluate the sorption behavior of tungstate and arsenate, both individually and in combination, using a “Langmuir-type” model. Both anions exhibited the highest sorption in acidic soils and the lowest in alkaline soils. While the shapes of the isotherms were similar in both single and binary systems, the maximum sorption values decreased when a co-occurring anion was present. These reductions can be attributed to competition for soil sorption sites, which have a high affinity for both anions. In all tested soils, the percentage decrease in arsenate sorption in the presence of tungstate was greater than the decrease observed for tungstate in the presence of arsenate. Gaining a deeper understanding of tungsten’s sorption mechanisms is critical, not only for advancing environmental research but also for informing regulations that currently give limited attention to the presence of tungsten in soils.

Dignified Branding and Its Role in the Cryptomarket

The advent of decentralized digital economies, particularly in the cryptomarket, necessitates new and ethical marketing approaches that prioritize transparency, trust, and long-term value. Dignified Branding (DB), a concept introduced by Mandeep Gupta, proposes a revolutionary shift away from the traditional commission-driven network marketing model by focusing on community-driven, volunteer-based product promotion. This paper examines the core principles of Dignified Branding and its potential impact on the cryptomarket. The absence of financial incentives, commissions, and competitive influences in DB creates a novel approach, one that aims to build trust, promote education, and ensure that the entire community benefits rather than individual investors.

Bank competition and ESG performance‐evidence from Chinese listed firms

AbstractThis study employs a two‐way fixed effects model to investigate the influence of bank competition on ESG performance of local firms and its underlying mechanisms based on the geographical distribution of bank branches and firms. Our results show that the increased level of competition among banks contributes positively to the ESG performance of firms and the promotion effect is more prominent in small firms, young firms, and nonstate‐owned firms. Industry heterogeneity analysis indicates that bank competition could be more beneficial for the sustainable development of low‐pollution, low‐tech industries, and industries that have a higher linkage with the financial industry. The mechanism analysis further reveals the mediating effect of financial constraints, green innovation, and moral hazards on firms' ESG performance. This study extends the existing understanding of the firm‐level consequences of bank competition and sheds light on the financial development drivers of corporate ESG performance in emerging market countries.

Relationship Corruption and Economic Growth ASEAN Countries

Corruption is a detrimental act for many people, especially related to the economy. Various groups widely discuss corruption and economic growth from academia, government, and the private sector. This is even more complex when coupled with competitiveness between countries and democratic systems. So this study aims to analyze the influence of global competitiveness, corruption and democracy on economic growth in ASEAN countries. This study used panel data analysis methods in 7 ASEAN countries from 2014-2019. The seven countries are Indonesia, Malaysia, Thailand, the Philippines, Vietnam, Laos, and Cambodia. It is related to economic growth, corruption, and competitiveness in ASEAN countries. The results of this study show that corruption brings mudhorot but has yet to be significant to economic growth. Another interesting finding is that democracy negatively affects global competitiveness and increases economic growth. This research can be one of the government's policy recommendations by increasing economic growth through strict enforcement against corruption and increasing global competitiveness. To realize economic growth that prospers society requires the role of the government through increasing human and institutional resources to support other competitiveness factors that focus on technological, environmental, and innovation aspects

The Influence of Market Competition on SMEs’ Performance in Emerging Economies: Does Process Innovation Moderate the Relationship?

Small and medium enterprises (SMEs) are vital to the economic development of emerging economies, significantly contributing to employment, innovation, and GDP growth. This study investigates the influence of market competition on SME performance in emerging economies, specifically examining the moderating role of process innovation. Using a sample of 365 SMEs in the western region of Ghana, the research employed a convenience sampling technique to gather data. The analysis utilized partial least square structural equation modeling (PLS-SEM) to explore the relationships between market competition, process innovation, and SME performance. The findings revealed that three direct hypotheses were supported, indicating a positive relationship between market competition and SME performance, while the moderated hypotheses were not supported. These insights provide valuable implications for SME owners, managers, and policymakers.

MARKETING PRIORITIES OF COMPANIES IN THE INTERNATIONAL PHARMACEUTICAL MARKET

The article presents the current trends in the development of the international pharmaceutical market and systematizes the priority areas for implementing marketing approaches of the leading companies. The purpose of this article is to reveal the marketing priorities of international pharmaceutical companies in the context of global challenges. To study this issue, a set of methods was used, namely: analysis and synthesis, statistical method, process and institutionalist approaches, case study.The results of the study show that the international pharmaceutical market is characterized by a high level of dynamism, preservation of the priority share of economically developed countries in revenue generation, significant influence of regulatory mechanisms at the national and international levels, and active processes of economic competition through mergers and acquisitions. The analysis has shown that the modern concept of pharmaceutical marketing goes far beyond the established narrow interpretation as a set of tools for the production, sale and promotion of a pharmaceutical product and is characterized by a high level of adaptability to the challenges of the global marketing environment of the twenty-first century. The article reveals the focus of marketing of leading companies on such priorities as: scaling up marketing budgets, ensuring synergy between marketing and financial indicators of pharmaceutical companies, modernizing communication strategies by optimizing interaction with key opinion leaders, intensifying multichannel marketing, etc.The theoretical significance of the study is to deepen the concept of international marketing in the context of its individual sectoral manifestations, taking into account the influence of global competition, institutional regulations, and technological progress. The practical value is due to the potential of using local or regional benchmarking for domestic companies participating in the international pharmaceutical market. Prospects for further research are considered in the direction of assessing the mechanisms and effects of the introduction of marketing innovations in the field of international pharmaceuticals.

‘Slim pickings?’: Extreme large recruitment events may induce density-dependent reductions in growth for Alaska sablefish (Anoplopoma fimbria) with implications for stock assessment

Growth processes mediate survival and fecundity within fish populations, which are fundamental in regulating population dynamics. Therefore, accurate estimates of population scale and sustainable exploitation levels in contemporary fishery stock assessment models rely heavily on understanding and accurately characterizing growth processes. However, empirical studies that relate population-level changes in growth patterns to observable ecosystem and population conditions remain scarce. In particular, few studies directly consider the influence of intra-specific competition (i.e., cohort effects) on growth variability, and its associated implications for stock assessment estimates. Focusing on Alaska sablefish as a case study, we illustrate how multiple unprecedented large recruitment events since 2014 resulted in density-dependent declines in growth on the population-level scale, using a state-space growth model. Furthermore, we demonstrate how incorporating cohort-specific growth variability within the Alaska sablefish stock assessment model resulted in substantial differences in estimates of spawning biomass and recommended harvest levels. Overall, results from this study underscore the significance of cohort effects on growth processes and their implications for stock assessment models and associated harvest recommendations.

How does market competition affect the reporting of sustainability practices? Insights from the UK and Germany

PurposeThis study tests the proprietary cost of reporting sustainability practices. It explores how market competition impacts the reporting of corporate sustainability information. Further, it examines whether the influence of market competition on sustainability reporting is affected by firm size.Design/methodology/approachIt uses two samples of the UK FTSE 350 and German Frankfurt CDAX nonfinancial firms from 2010 to 2023. The sustainability reporting scores for UK and German firms are their Environmental, Social and Governance (ESG) disclosure scores based on the Bloomberg disclosure index. The Herfindahl–Hirschman index has been utilized to measure a firm’s degree of market competition.FindingsThe results reveal that reporting sustainability practices is a negative function of the degree of market competition. Specifically, companies in highly competitive industries disclose less information about their sustainability practices, suggesting that firms view sustainability reporting as a potential source of competitive disadvantage and, therefore, choose to limit such disclosures to maintain a strategic advantage over rivals. Further, the findings reveal a negative impact of market competition on sustainability reporting among small firms. However, this effect is weak or absent among medium and large firms. The results are more observable in the liberal market economy (i.e. the UK) than in the coordinated market economy (i.e. Germany).Practical implicationsIt provides implications for policymakers and market participants to advocate for more significant policies that promote transparency and encourage companies to report their sustainability practices and performance, especially companies in highly competitive industries.Originality/valueIt provides the first evidence of how market competition influences corporate sustainability reporting, adding a deeper insight into another non-financial dimension of sustainability reporting. Likewise, it reflects the varying priorities of companies of different sizes in managing both competition and sustainability reporting. Besides, it is the first to explore this nexus in two distinct jurisdictions: the UK and Germany.

Factors and effects of inter-individual variability in silver birch phenology using dense LiDAR time-series

Comprehending and quantifying local variability in plant phenology, alongside its impacts on tree growth, is challenging due to spatially and temporally heterogeneous environmental factors that interact to affect phenological events and periods. Although previous studies have focused on the climatic factors driving phenological events at the stand level, the influences of competition, neighborhood characteristics, species richness, and water availability on plant phenology remain unclear. In the present paper, we used hourly terrestrial LiDAR surveys performed between April 2020 and April 2021 to investigate the influence of local factors (neighborhood and topography) on the phenology of silver birch trees (Betula pendula Roth.). We also examined how phenological events affect growth in tree height and crown area. All response and explanatory variables were estimated using LiDAR time-series data and a field survey campaign. Our findings demonstrate a high within-species variability in plant phenology that is controlled by biotic and abiotic characteristics of the ecosystem. We found that between tree variation in leaf burst, completion of the leaf growth and length of canopy growth period were affected by tree size, neighborhood species richness, level of suppression and competition, which potentially indicate plant responses to light availability. The beginning of senescence, completion of leaf drop, and length of autumn phenology were mostly affected by topographic water index, which reflects water availability and can be linked to nutrient availability and exposure to wind. Furthermore, we demonstrated that an earlier leaf burst, and delayed beginning of senescence were associated with larger absolute growth in canopy area but found no clear relationship between height growth and phenology. Our study highlights the capability of dense, high-quality LiDAR time-series to detect significant phenological variation among individuals of the same species within the same locality, demonstrating the potential of LiDAR time-series as a tool for understanding phenology and its impacts.

ВПЛИВ МІЖНАРОДНОЇ КОНКУРЕНЦІЇ НА СТРАТЕГІЧНИЙ РОЗВИТОК ЕКОНОМІКИ КРАЇНИ

The study draws attention to the problems and prospects of sustainable strategic development of the national economy. That is why the purpose of the article is the further development of methodological and applied principles and approaches to analyzing the impact of international competition on the strategic development of the country's economy. Scientific views on the interpretation of international competition are summarized, in particular, according to the geopolitical, economic, resource, political and institutional approach. The main factors of the influence of international competition on the strategic development of the national economy have been determined, namely in terms of the possible rapid accumulation of economic resources by the country, the availability of information about prospective and current needs of potential buyers, ensuring the country's competitiveness on the international market, the favorability of the national system of economic support and the development of factor competitive advantages. The trends of international competition and expected changes in the strategic development of the country's economy have been identified and characterized, in particular in terms of such components as the technologicalization of the world economy, the blurring of global industry boundaries, the globalization of international competitive relations, the polarization of world market segments, the deregulation of world market segments. The most significant manifestations of international competition have been identified, which relate to the global nature of international competition, its multifacetedness, dynamism and aggressiveness of competitive rivalry, which leads to violations in stability and balance in the economies of competing countries. The directions of the strategic development of the national economy are determined, depending on the influence of factors of international competition on it.

The Influence of Social Competition and Maths Anxiety on Game Performance

Digital Game-Based Learning (DGBL) uses serious games to deliver educational content. DGBL has the potential to aid children’s development of maths skills, providing educators with alternatives to traditional mathematics teaching. However, the efficacy of serious games can be affected by their attributes, including whether they are single or multi-player. While competition in a multi-player environment may enhance players’ interest and motivation, potential social pressure may lead to anxiety and affect performance. In maths education, there are additional challenges. Mathematics Anxiety (MA), the negative emotional response to mathematics, may interact with game features and impact players’ experience. This study assesses players' performance in a digital maths game called ’Seven Spells’ across two different game modes (vs. Human and vs. CPU), and it also investigates whether MA levels impacted players’ performance. 43 children from two classes in an Irish primary school participated in thisstudy. Each class played a different game mode of the ‘Seven Spells’ game, one group playing against computer-controlled characters (vs. CPU) and the other playing against their classmates (vs. Human). The game mechanics were identical between the two competition game modes. The children completed the modified Abbreviated Mathematics Anxiety Scale (mAMAS) and a mathematics questionnaire before participating in the intervention, which included 4 sessions. They also participated in a focus group session at the end of the intervention. Data on their gameplay were collected throughout the first three sessions and analysed through multiple linear regression models to investigate possible connections between MA, maths knowledge, game modes and game performance. The results of the multiple linear regressions indicate that game performance was positively influenced by the duration of gameplay and the complexity of moves — measured by the number of moves and cards used — while being negatively affected by MA. However, a significant interaction between MA and the competition game mode was observed, suggesting that MA had a more pronounced negative impact on players in the vs. Human game mode compared to the vs. CPU game mode.

Experimental and modeling studies on char combustion under pressurized O2/H2O conditions

The desorption kinetic parameters for pressurized combustion and gasification reactions were determined based on a C++ program coupled with the Langmuir-Hinshelwood (L-H) kinetic model developed and experimental data from pressurized char combustion, and the established L-H kinetic model for pressurized char-O2/H2O combustion was refined in the current paper. The activation energy for desorption in reactions involving pressurized char-O2 and char-H2O was determined to be 250.8 kJ/mol, accompanied by a pre-exponential factor of 5.42×1010 g/(m2 s). Using this foundation, the current research conducted simulations to investigate the impacts of temperature, pressure, and H2O concentration on the oxidation adsorption rate (Rads,oxi), desorption rate (Rdes), gasification adsorption rate (Rads,gas), and the competitive influences of kinetics and diffusion processes within the pressurized char-O2/H2O combustion. The simulation results indicate a gradual increase in Rdes and Rads,gas with char conversion to reach a peak, followed by a gradual decline. Conversely, the Rads,oxi varies smoothly throughout the char conversion process. At 1673 K/1.0 MPa, the char-O2/H2O reaction rate is primarily constrained by Rads,oxi and Rads,gas, with the adsorption reaction serving as the rate-controlling step. Moreover, it was noted that a rise in pressure resulted in a linear increase in Rads,oxi, Rdes, and Rads,gas. At elevated temperatures, the impact of pressure on them becomes more noticeable. However, the introduction of H2O mitigates this effect. Elevated temperature and pressure facilitate the competition on the kinetics of char-O2 combustion for O2 diffusion, resulting in the conversion of char being more susceptible to O2 diffusion rate limitation. With the addition of 20% H2O, the competition effect was weakened. In the case of pressurized combustion involving char and O2/H2O, the char conversion is primarily constrained by the O2 diffusion rate and is scarcely influenced by the H2O diffusion rate.
