Group Decisions, Between Competitive Motives and Knowledge Sharing

This research was conducted on UMKM groups established based on program instrumentation in the form of community development. The focus of this research is on the dynamics and processes that involve groups as strategic alliances between knowledge sharing and competitive motives. This research uses a qualitative approach with a case study method. Data was collected through in-depth interviews and focus group discussions. Identification of research informants was done by snowball sampling through key informants of group leaders and former group mentors. Triangulation of sources and methods was used to ensure the validity of the data. Field data will be collected, classified, reduced, and then interpreted according to the Miles and Huberman method. The group will be able to work and evolve if there is a reciprocal process of interests among its members, such as sharing knowledge. Between competitive motives and the process of sharing knowledge will potentially negate each other in group dynamics. Therefore, this dynamic requires factors that can ensure a balance between the two. How to keep competitive motives at a healthy competitive level and, on the other hand, not interfere with the process of sharing knowledge, which is one of the indicators that the group is working and developing.

Performance variables and nutritional status analysis from Moroccan professional and adolescent football players during the competition period: a descriptive study

IntroductionNutrition plays an integral role in optimizing football players’ performance during training sessions and matches and maintaining their overall health throughout the season. This study aimed to evaluate how well the dietary practices of professional and adolescent football players in Morocco during the competitive period met international macronutrient recommendations, and to explore the relationship between their nutritional status and aerobic performance, as measured by the Yo-Yo IRL1 test.MethodsA total of 277 footballers from Morocco's professional league, “Botola-Pro”, were monitored over a seven-day (training microcycle) during the competitive period. The dietary intake was assessed through self-reported methods and 24-hour recalls. Relevant body composition was measured with bioelectrical impedance (BI), and aerobic performance was evaluated using the Yo-Yo IR test.ResultsThe results indicated significant variations in performance and nutritional status across different categories and age groups. The nutritional status of the players didn't match the UEFA recommendations (p < 0.001). We found that higher intake levels of carbohydrates and proteins were positively correlated with the total distance covered by the players (p < 0.001, r = 0.63, R2 = 0.4 for carbohydrates; p < 0.001, r = 0.59, R2 = 0.35 for proteins). Conversely, a higher proportion of energy derived from fats in the diet was negatively correlated with the distance covered (p < 0.001, r = −0.64, R2 = 0.41).ConclusionThese findings suggest that optimizing carbohydrates and protein intake while managing fat consumption is crucial for enhancing sporting performance. This information is essential for tailoring training programs and nutritional regimens based on the competition level.

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.

Effects of Working Capital Management on Small-Sized Businesses in Competitive Environments with Economic Policy Uncertainty—A Case Study Applied to Chilean Companies

Working capital is a strategic resource that not only enhances financial performance but also ensures the long-term sustainability of organizations, especially SMEs. In the context of evolving economic policies and the challenges of gender equity affecting Chilean companies, this study explores how economic policy risk (EPU) and CEO characteristics influence working capital, which are essential investments for sustainable growth. The analysis covers 12,839 SMEs from 2014 to 2019. Using a fixed-effects panel data model, the findings reveal that firms tend to increase their investment in working capital in response to rising economic policy uncertainty. However, the relationship follows a non-linear inverted U-shaped pattern, which suggests the existence of an investment optimum between working capital and the EPU. Considering the level of competition, companies increase their investment in working capital when the level of competition is higher. Regarding the gender and age of CEOs, it is observed that women invest less in working capital, as do young CEOs. These results underscore the importance of EPU, along with the gender and age of CEOs, as key factors in promoting sustainable working capital management.

Analysis of the Competitiveness of Digital Service Trade Between China and RCEP Partner Countries

Abstract: Based on the digital service trade data from China and RCEP partner countries from 2008 to 2022, this study analyzes the current status of digital service trade, including export scale, structure, and policies. It calculates the international market share and trade competitiveness index, and provides an in-depth analysis of the overall competitiveness of digital service trade and the competitiveness levels by industry within RCEP countries. The study finds that while the international competitiveness of digital service trade between China and RCEP partner countries is relatively weak, the development speed is relatively fast. In response, China should increase efforts in digital infrastructure construction with RCEP partners, promote digital technology research and innovation; enhance digital security and privacy protection, and improve relevant laws and policies; reduce barriers to digital service trade, and increase the influence in formulating digital trade rules; strengthen political mutual trust among RCEP countries, and deepen cooperation in digital service trade.

The Great Powers Competition and Increasing Entropy in the Local Media Across Africa and Asia

Abstract The current United States National Defense Strategy prioritizes strategic competition with Russia and China, whereas for the previous two decades, the priority was counter-terrorism. This research aims to measure the extent to which competition among great powers is intensifying and identify where such intensification is taking place. To achieve this, we utilize a large, open-source dataset called GDELT 2.0, which provides an archive of global news articles. We calculate the entropy for local press coverage of great powers (e.g., the United States, China, Russia, France, and India) across 96 African and Asian nations to measure static competition levels. Additionally, we identify African and Asian nations where competition levels have changed significantly between 2015 and 2020. Our findings show that seven countries are experiencing increased competition among great powers, whereas seven other countries experience increased domination by one great power. When we aggregate the data geographically, we find that Southeast Asia is the only subregion where there is a significant decrease in competition. Our results align with the primary concern of the National Defense Strategy: that American influence is decreasing. Specifically, we have identified increased competition across Africa and increased domination across Asia. These trends are due to a relatively higher reporting of Chinese in-country public and private entities between 2015 and 2020.

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.

Surviving Science – Coping with Exit-Decisions in Physics and History

AbstractAcademic careers between the completion of a PhD and the acquisition of tenure are characterized by short term contracts, high levels of competition, and future uncertainty. Existing research indicates that uncertainty is a primary cause for postdocs in all disciplines to constantly question the continuation of their career. Despite this commonality between disciplines, we argue that future imaginations, coping strategies and ultimately the decision-making practices to exit or remain in academia differ in each discipline. Drawing from 60 qualitative interviews with physicists and historians, we compared imaginations of the labor market inside and outside of academia, as well as narratives on how they perceive their agency to exit or remain. Our data shows that imaginations of the labor market outside of academia, have considerable consequences for their sense of precarity and planning of career paths. We propose that the uniform concept of future uncertainty must be separated into ‘existential uncertainty’ and ‘secured uncertainty’, which more accurately reflect the problems postdocs are confronted with and the resulting coping strategies. While those who consider their uncertainty as existential either evoke narratives of survival to continue in adverse conditions or begin parallel careers as added security. Those who perceive their future as uncertain but generally secured rely either on their ability to decide when necessary or postpone the question indefinitely. These differences that correlate with our chosen disciplines have important implications for research quality as well as mental-health hazards and further our understanding of self-exploitation and precarity in academia.

Chronotype, sleep hygiene, and sleep characteristics among athletes of different disciplines.

The objective of the study was to assess chronotype, sleep hygiene, and sleep characteristics of Italian athletes in order to identify differences among sport disciplines (team- vs individual-sports), level of competition (Elite vs Non-Elite) and sexes. Moreover, correlations between chronotype, sleep hygiene and sleep quality were evaluated. Two hundred eighty Italian athletes (Females:113; Males:167) participated in the study. They completed the Pittsburgh Sleep Quality Index (PSQI), the Sleep Hygiene Index (SHI) and the MorningnessEveningness Questionnaire (MEQ). Among the athletes, 66.4% were intermediate-type, 21.8% were morning-type and 11.8% were evening-type. 55.4% of the sample was classified as good sleeper (PSQI<5), while 16.1% had poor sleep hygiene (SHI≥35). Females had higher total sleep time (p=0.022) than males. Individual-sports showed more morning-oriented score (p=0.001) and lower PSQI (p=0.006) and SHI (p<0.001) scores, with earlier timing of sleep (bedtime:p<0.001; wake-up time:p<0.001) compared to teamsports. Elite athletes exhibited greater sleep efficiency (p=0.009), and lower sleep latency (p=0.018) and wake after sleep onset (p=0.043) than Non-Elite athletes. Additionally, significant correlations were found between PSQI and SHI (r=0.43, p<0.001), and between MEQ and SHI (r=-0.35, p<0.001). This study yields crucial insights into the sleep behaviors of Italian athletes, revealing that nearly half of the sample were bad sleepers.

Measuring sustainable transformation of small and medium‐sized enterprises using management systems standards

AbstractSmall‐ and medium‐sized enterprises (SMEs) represent a significant number of industries in need of moving towards more sustainable development. A sustainability perspective on business activities is today crucial for SMEs to achieve a new level of competitiveness. Identifying which is a suitable set of sustainability indicators for an individual SME is a big challenge. The availability of so many methods and systems can leave SMEs reluctant to implement them in their small business. Therefore, this research aims to create a sustainability maturity model for SMEs to visualize goals and assess progress on their transformation journey. Progress is assessed by indicators, exemplified by indicators of the Global Reporting Initiative and the maturity is verified as stepwise growth along international management system standards. Using the developed model, it is possible to determine the SMEs' sustainability performance. The research has resulted in a stepwise classification of the organization's maturity is compiled into training and auditing material in different regions and sectors.

MARKETING DIGITAL PARA STARTUPS: MARKETING DIGITAL PARA MICROEMPRESÁRIOS, UMA IDEIA REVOLUCIONÁRIA PARA ALCANÇAR O SUCESSO

Who never faced lines to make a payment or even to buy a certain product. Some time ago we did this, wasting hours in market lines, banks, bookstores and airports. Nowadays we can do all of this, without having to queue, without leaving home or watching a movie; reducing waiting time, being able to receive at home. All of this is in the consumer's possession, through his Smartphone device. As a result, the importance of developing and working on an action plan with digital marketing grows; because every person who has a device your company will be there too. It is possible to ask scientifically how Digital Marketing is a factor influencing consumer behavior in the Brazilian economic sector, how often consumers buy over the internet. What companies face today is not a lack of inputs (raw materials and components), or service companies. And, yes, the lack of loyal customers (followers). Contemporary companies can manufacture products beyond what customers can consume. This increases the level of competition in the competitive market, and consumers are the winners. The success of an electronic business depends on many factors. It is not enough for the company to have a welltructured website, with an attractive design and the best technologies. Companies and startups must go beyond the perception of customers, they must engender a profitable reciprocal familiarity. The company needs to define its position in the market, and envision possible future scenarios. Digital Marketing is an undeniable reality that has been joining forces with traditional commerce, a versatile means of communication that integrates sales opportunities, customer relations and positive word of mouth advertising.

Examining trade strategies in Europe and Ukraine: Navigating challenges and building economic strength

Today, the global community operates within an integrated global economic system. Against the backdrop of globalised integration of the socio-economic sphere, international trade is positioned as a significant factor in the intensification of economic development. In this context, trade strategies can create new opportunities or risks for the national economy. This article aims to conduct a comparative analysis of the trade strategies of the European Union (EU) and Ukraine in the context of potential advantages and related challenges for economic resilience. The study finds that international trade helps to mitigate the limitations of national resource potential and the narrowness of the domestic market, intensifies the potential for innovative industrialisation, and accelerates economic growth. The specifics of forming the modern concept of international trade development in the context of the European community and Ukraine are identified. The main principles of modern trade strategies are considered, their strengths and weaknesses are analysed, and directions for improvement are highlighted. The impact of trade strategies on the level of economic resilience is examined. It is substantiated that a high level of competition in the global market requires the adaptability of producers’ trade strategies and the formation of appropriate structures to coordinate the functioning of the external economic relations infrastructure complex. The main success factors of a trading strategy when entering new markets are highlighted, including preliminary research of local legislation requirements and market dynamics, the development of adaptive marketing strategies, and effective management of customs processes. Active participation in the international trade environment has proven to open additional opportunities for realising economic potential. At the same time, it is necessary to specify the development strategy to ensure long-term competitive advantages.

Teacher Training Dynamics: Positive and Negative Interdependence in Moroccan Training Centers

This study explores the dynamics of competition and collaboration among trainee teachers at the Centres Régionaux des Métiers de l’Éducation et de la Formation (CRMEF) in Morocco. Given the increasing precarity in teacher training centers and the heightened emphasis on effectiveness and academic excellence, the research examines how these factors shape trainees' learning environment and professional development. Using Social Interdependence Theory, the study assesses how varying levels of competition and collaboration impact trainees' attitudes, behaviors, and overall performance, offering insights into their educational experiences and outcomes. The study employed an exploratory sequential design, beginning with data from two focus group discussions to develop a survey, which was then administered to 157 participants from three regional academies. The findings reveal high levels of competition at the CRMEF, contributing to increased stress and reduced teamwork effectiveness. However, trainees demonstrate strong collaboration in group tasks while displaying competitive behaviors during individual tasks. The study suggests that team-based assessments could mitigate the negative impacts of competition and enhance collaborative efforts.

Linda index forecast based on ARIMA time series

Competition in the telecommunications market has significant benefits and impacts in various fields of society such as education, health and the economy. Therefore, it is key not only to monitor the behavior of the concentration of the telecommunications market but also to forecast it to guarantee an adequate level of competition. This work aims to forecast the Linda index of the telecommunications market based on an ARIMA time series model. To achieve this, we obtain data on traffic, revenue, and access from companies in the telecommunications market over a decade and use them to construct the Linda index. The Linda index allows us to measure the possible existence of oligopoly and the inequality between different market shares. The data is modeled through an ARIMA time series to finally predict the future values of the Linda index. The results show that the Colombian telecommunications market has a slight concentration that can affect the level of competition.

Trails, traits, and mental states: Psychological differences between competitive and recreational sub-ultra and ultramarathon runners

Psychological trait differences between ultrarunners (completing more than a standard 42.195 km marathon) and sub-ultrarunners (≤42.195 km) have been assumed, but not robustly examined. The current study investigated trait differences between competitive and recreational runners at sub-ultra and ultramarathon distances. Six hundred and eleven participants (334 recreational, 400 sub-ultrarunner) completed an online, anonymous survey assessing five traits: mental toughness (MT), grit, motivation, general self-efficacy (GSE), and personality. Bayesian ANOVAs indicated at least moderate evidence for differences within Distance for grit-perseverance of effort (PE) and intrinsic motivation (IM), such that ultrarunners scored higher than sub-ultrarunners. Similarly, we observed at least moderate evidence that competitive runners scored higher than recreational runners on overall grit, grit-PE, GSE, IM, and extrinsic motivation (EM). Interaction effects provided moderate evidence for greater MT and overall grit in competitive ultrarunners. Evidence for other differences were anecdotal or favoured the null hypothesis. This study represents a novel investigation into the psychological makeup of runners. We suggest that aspects of motivation, grit, and self-efficacy, but not personality, may differentiate competitive from recreational runners, and ultrarunners from sub-ultrarunners. The identification of these trait differences may benefit runners and coaches wanting to progress in distance or competition level, with broader application to workplace or academic contexts. Further research is needed to develop a clearer conceptualisation of mental toughness, and build upon the novel findings of this study, particularly given the paucity of literature that exists within this context.

Concussion Incidence by Type of Sport: Differences by Sex, Age Groups, Type of Session, and Level of Play An Overview of Systematic Reviews With Meta-analysis.

OBJECTIVES: To (1) summarize pooled prevalence and incidence rates of concussion by type of sport and (2) synthesize the differences in prevalence or incidence rates of concussion by type of sports in terms of sex, age, type of session, and level of competition. DESIGN: An overview of systematic reviews with meta-analysis. LITERATURE SEARCH: CINAHL, Embase, Epistemonikos, PubMed, Scopus, SPORTDiscus, and the Cochrane Library databases were searched. STUDY SELECTION CRITERIA: Systematic reviews with meta-analyses reporting pooled incidence or prevalence of sport-related concussion. DATA SYNTHESIS: AMSTAR 2 was used to assess the methodological quality of reviews. Overlap between reviews was calculated. RESULTS: Ten systematic reviews with meta-analysis were included, all evaluating incidence rates of concussion. There were no meta-analyses of concussion prevalence. Concussions seem to have a higher incidence in rugby, snowboarding, ice hockey, and American football. In reviews that explored sex-based differences across subgroups, there was a higher incidence rate of concussion in baseball-softball, basketball, and soccer in females compared to males. There were no age subgroups analyzed. The incidence of concussions was higher during games compared to practice in American football, ice hockey, rugby, and soccer. Amateur rugby had higher concussion rates compared to professional rugby. CONCLUSIONS: Rugby, snowboarding, ice hockey, and American football had the highest incidence rate of concussion when no other differences (eg, type of session) were considered. However, important methodological flaws were detected, such as the lack of use of the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) system and subgroups for specific factors (eg, age groups).

Does centralization of tax administration regulate tax competition? Evidence from a quasi-natural experiment in China

This study investigates how the centralization of tax administration affects tax competition among local governments in China, using the merger of the State Tax Bureau and Local Tax Bureau in 2018 as a quasi-natural experiment. Our findings demonstrate that the centralization of tax administration effectively curtails the degree of tax competition among local governments, resulting in an increase in the tax burden for enterprises previously managed by the local tax bureaus. Mechanism tests indicate that the reform significantly increases the tax burden on enterprises in regions with high levels of tax competition, and overall reduces the divergence of tax burden among enterprises, restraining cross-regional investments driven by tax avoidance. Additionally, we find that after the means of tax competition among local governments are curtailed, competition continues through fiscal expenditure. Our study provides evidence from China on curbing inter-governmental tax competition from the perspective of administrative institutional reform.
