Navigating Exploitative Traps: Unveiling the Uncontrollable Reward Seeking of Individuals With Internet Gaming Disorder.

BACKGROUND: Internet gaming disorder (IGD) involves an imbalance in the brain's dual system, characterized by heightened reward seeking and diminished cognitive control, which lead to decision-making challenges. The exploration-exploitation strategy is key to decision making, but how IGD affects this process is unclear. METHODS: To investigate the impact of IGD on decision making, a modified version of the 2-armed bandit task was employed. Participants included 41 individuals with IGD and 44 healthy control individuals. The study assessed the strategies used by participants in the task, particularly focusing on the exploitation-exploration strategy. Additionally, functional magnetic resonance imaging was used to examine brain activation patterns during decision-making and estimation phases. RESULTS: The study found that individuals with IGD demonstrated greater reliance on exploitative strategies in decision making due to their elevated value-seeking tendencies and decreased cognitive control. Individuals with IGD also displayed heightened activation in the presupplementary motor area and the ventral striatum compared with the healthy control group in both decision-making and estimation phases. Meanwhile, the prefrontal cortex showed more inhibition in individuals with IGD than in the healthy control group during exploitative strategies. This inhibition decreased as cognitive control diminished. CONCLUSIONS: The imbalance in the development of the dual system in individuals with IGD may lead to an overreliance on exploitative strategies. This imbalance, marked by increased reward seeking and reduced cognitive control, contributes to difficulties in decision making and value-related behavioral processes in individuals with IGD.

Harmonious passion and academic achievement in higher education: The mediating influence of exploratory and exploitative learning strategies.

Harmonious passion refers to engaging in an activity out of personal volition and sense of meaning, which motivates individuals to devote substantial time and energy while internalizing the activity as part of their identity, and it underpins the promotion of sustainable behaviors and mindsets. The present study aimed to investigate the relationship between harmonious passion and academic achievement among university students in higher education, as well as the mediating role of exploratory and exploitative learning behaviors in this association. Exploratory learning involves seeking new knowledge and skills, whereas exploitative learning involves refining and applying existing knowledge and skills. Data were collected from 528 university students across multiple institutions in China. Using structural equation modeling and multiple regression analysis, results revealed that harmonious passion had a significant positive effect on academic achievement. Furthermore, exploratory and exploitative learning played a chain-mediated role in the relationship. These findings provide insights into how harmonious passion could promote students' academic success in the context of innovation-driven and socially sustainable development, via the facilitation of sustainable learning strategies. Therefore, this study has broader implications for personal and societal sustainability, by emphasizing the role of harmonious passion and sustainable learning strategies in enhancing academic achievement and, ultimately, contributing to a more sustainable society.

Mechanisms and implications of bacterial-fungal competition for soil resources.

Elucidating complex interactions between bacteria and fungi that determine microbial community structure, composition, and functions in soil, as well as regulate carbon (C) and nutrient fluxes, is crucial to understand biogeochemical cycles. Among the various interactions, competition for resources is the main factor determining the adaptation and niche differentiation between these two big microbial groups in soil. This is because C and energy limitations for microbial growth are a rule rather than an exception. Here, we review the C and energy demands of bacteria and fungi-the two major kingdoms in soil-the mechanisms of their competition for these and other resources, leading to niche differentiation, and the global change impacts on this competition. The normalized microbial utilization preference showed that bacteria are 1.4-5 times more efficient in the uptake of simple organic compounds as substrates, whereas fungi are 1.1-4.1 times more effective in utilizing complex compounds. Accordingly, bacteria strongly outcompete fungi for simple substrates, while fungi take advantage of complex compounds. Bacteria also compete with fungi for the products released during the degradation of complex substrates. Based on these specifics, we differentiated spatial, temporal, and chemical niches for these two groups in soil. The competition will increase under the main five global changes including elevated CO2, N deposition, soil acidification, global warming, and drought. Elevated CO2, N deposition, and warming increase bacterial dominance, whereas soil acidification and drought increase fungal competitiveness.

Effect of empowerment: how and when do high-involvement work practices influence elder employees' innovative performance?

Introduction: In today's fast-paced business environment, innovation from elder employees is increasingly vital to organizations. High-involvement work practices that emphasize engagement and empowerment have a significant impact on the innovation performance of these employees, harnessing their wealth of experience and fostering organizational growth. However, most of the current research on innovation performance focuses on the single factor of the individual or the organization, and most of them focus on the linear relationship; research on the factor of human resource practices, in particular high-involvement work practices, is inadequate. Methods: Based on social exchange theory, this paper uses structural equation modeling (SEM) to examine the impact of high-involvement work practices on elder workers' innovation performance using 278 valid samples from three time points, and the non-linear effects of exploratory and exploitative innovation on elder workers' innovation performance. Results: (1) There is no significant relationship between high-involvement work practices and elder employees' innovation performance. (2) Exploratory innovation has a significant U-shaped relationship with innovation performance, i.e., as the level of exploratory innovation increases, the innovation performance of elder employees first decreases and then increases. There is a significant inverted U-shaped relationship between exploitative innovation and innovation performance, i.e., as the level of exploitative innovation increases, innovation performance first increases and then decreases. High-involvement work practices have a U-shaped effect on elder employees' innovation performance through exploitative innovation. (3) Transformational leadership moderates the direct effects of high-involvement on exploratory innovation and elder employees' innovation performance, and transformational leadership moderates the U-shaped effect of high-involvement work practices on elder employees' innovation performance through exploratory innovation. Discussion: The conclusion is helpful for organizations to enhance elder employees' innovation performance by enriching high-involvement work practices.

The broken trust: how exploitative leadership damages employee work passion.

This study explores how exploitative leadership affects employees' work passion, a vital element for engagement, creativity, and productivity. It further delves into how trust in leaders mediates this relationship. By applying social exchange theory and conservation of resources theory and analyzing responses from 384 full-time employees through covariance-based structural equation modeling using SmartPLS, the findings confirm the negative effects of exploitative leadership on work passion. They also underscore the significant mediating role of trust in leaders. These insights underline the importance of addressing exploitative leadership in organizational policies and enhancing trust to improve work passion. The study not only provides valuable information for organizations but also lays the groundwork for future research on leadership styles, trust, and employee passion.

Competitive interactions and coexistence of sympatric flagship carnivores in Asia.

Understanding the competition and coexistence of flagship carnivores is key to creating strategies for their conservation in the face of global carnivore declines. Although studies exploring the dynamics and competition between tigers (Panthera tigris) and leopards (P. pardus) span decades, there is a lack of understanding regarding the factors that influence their coexistence mechanisms on a broad scale, as well as the drivers determining their exploitative and interference competition. We gathered a comprehensive list of research papers among which 36 papers explored the interspecific interactions between tigers and leopards and tested the influence of biotic and abiotic factors on the coexistence mechanisms along three dimensions using multiple response variables regression models; we also tested the influence of ecological drivers determining the exploitative or interference competition between tigers and leopards. Elevation and ungulate density were the most important predictors in regulating the coexistence mechanisms. Tigers and leopards exhibited more positive relations/higher overlaps as elevation increased in the spatial niche. In addition, they showed a higher dietary overlap in the prey-rich regions. We determined that interference competition between tigers and leopards was less frequently observed in habitats with dense tree cover and homogeneous vegetation structures. Meanwhile, studies with multiple metrics would promote the detection of interference competition. Our study provides new insight into the competitive interactions and coexistence mechanisms of tigers and leopards on a broad scale. Policy-makers and managers should pay more attention to the factors of elevation, prey abundance, and habitat structures for the conservation of tigers and leopards.

Expanding the dimensions of knowledge hiding: testing a moderated mediation model and analyzing the mediating role of psychological distress using PLS-SEM.

This study sheds light on the literature on knowledge-hiding behavior in organizations and highlights a better and deeper understanding of the reasons for giving rise to knowledge hiding. In recent decades, knowledge hiding has been subjected to numerous studies in systematic literature reviews and organizational management regarding its impact on outcomes such as individual and organizational performance; however, the mechanism by which knowledge hiding is influenced by antecedents and the process of leading knowledge hiding has not been actively verified. In addition, most previous studies have classified knowledge hiding into one-factor or three-factor dimensions: evasive hiding, playing dumb, and rationalized hiding. To address these issues and limitations, we aimed to conduct empirical research, which have focused on four new dimensions (playing dumb, evasive hiding, rationalized hiding, and procrastination) of knowledge-hiding behavior. Unlike previous research, we provide a research framework for the process of hiding knowledge and verify the significance of the research model, drawing on the social exchange theory and conservation of resources theory to explore and verify the process of hiding knowledge. Specifically, we argue that knowledge hiding is caused by exploitative leadership, and psychological distress as mediators in the relationship between these two variables. Moreover, the moderating and mediating effects of leader incivility were verified. To empirically test the research model, a survey was conducted with 287 employees from small- and medium-sized enterprises in China. Partial least squares structural equation modeling (PLS-SEM), SPSS PROCESS, and AMOS software were used for statistical analyzes. The findings provide evidence that exploitative leadership positively influences both psychological distress and the four dimensions of knowledge hiding. In addition, the mediating effect of psychological distress and the moderating effect of leader incivility were verified and shown to be statistically significant. Based on these findings, the theoretical and practical implications, limitations, and directions for future research are discussed. Overall, the most important contribution is expanding the research field, as this is the first empirical study on the four dimensions of knowledge hiding.

Disentangling Exploitative and Interference Competition on Forest Dwelling Salamanders.

Exploitative competition and interference competition differ in the way access to resources is modulated by a competitor. Exploitative competition implies resource depletion and usually produces spatial segregation, while interference competition is independent from resource availability and can result in temporal niche partitioning. Our aim is to infer the presence of spatial or temporal niche partitioning on a two-species system of terrestrial salamanders in Northern Italy: Speleomantes strinatii and Salamandrina perspicillata. We conducted 3 repeated surveys on 26 plots in spring 2018, on a sampling site where both species are present. We modelled count data with N-mixture models accounting for directional interactions on both abundance and detection process. In this way we were able to disentangle the effect of competitive interaction on the spatial scale, i.e., local abundance, and from the temporal scale, i.e., surface activity. We found strong evidence supporting the presence of temporal niche partitioning, consistent with interference competition. At the same time, no evidence of spatial segregation has been observed.

The predictive effect of relative intuition on social entrepreneurship orientation: How do exploratory and exploitative learning and personal identity interact?

This study complements the stream of psychology studies on the effects of an individual's intuition on strategic decisions and how it shapes behavioral tendencies by extending how these effects evolve social entrepreneurship orientation in social entrepreneurship. Theoretically, we establish the nexus between relative intuition and social entrepreneurship orientation as well as the moderating roles of exploratory and exploitative learning and personal identity. Empirical validation of these nexuses was based on a cross-section of 276 certified social enterprises in China. The findings indicate that social entrepreneurs' relative intuition has a positive association with social entrepreneurship orientation. Exploratory and exploitative learning positively mediate the nexus between relative intuition and social entrepreneurship orientation. In addition, personal identity positively moderates the effects of exploratory and exploitative learning on social entrepreneurship orientation. Subsequently, we found that the link between relative intuition and social entrepreneurship orientation strengthens as the social entrepreneurs' personal identity increases. In this light, we identify relative intuition as the foundation of exploratory and exploratory learning for the development of social entrepreneurship orientation. Similarly, we shed light on how personal identity positively facilitates the roles of these factors by arousing dedication to the processes/stages of the pursuit of social entrepreneurship orientation goal attainment.

The relationship between slack resources and organizational resilience: The moderating role of dual learning.

Slack resources and organizational learning are key elements in building organizational resilience. This paper constructs an impact model of organizational resilience and investigates the impact of slack resources on organizational resilience using data from Chinese-listed companies, as well as verifying the moderating effect of organizational dual learning through hierarchical analysis. The findings show that: Firstly, both absorbed slack resources and unabsorbed slack resources promote organizational resilience. Secondly, organizational learning has a moderating effect on the relationship between slack resources and organizational resilience, where organizational exploitative learning positively moderates the relationship between unabsorbed slack resources and organizational resilience, while organizational exploitative learning negatively moderates the relationship between absorbed slack resources and organizational resilience. Accordingly, organizations should pay attention to the composition of slack resources and the coordination between slack resources and organizational dual learning in order to improve organizational resilience.

Decline in wild bee species richness associated with honey bee (Apis mellifera L.) abundance in an urban ecosystem.

The spatial heterogeneity of urban landscapes, relatively low agrochemical use, and species-rich floral communities often support a surprising diversity of wild pollinators in cities. However, the management of Western honey bees (Apis mellifera L.) in urban areas may represent a new threat to wild bee communities. Urban beekeeping is commonly perceived as an environmentally friendly practice or a way to combat pollinator declines, when high-density beekeeping operations may actually have a negative influence on native and wild bee populations through floral resource competition and pathogen transmission. On the Island of Montréal, Canada there has been a particularly large increase in beekeeping across the city. Over the years following a large bee diversity survey ending in 2013, there was an influx of almost three thousand honey bee colonies to the city. In this study, we examined the wild bee communities and floral resources across a gradient of honey bee abundances in urban greenspaces in 2020, and compared the bee communities at the same sites before and after the large influx of honey bees. Overall, we found a negative relationship between urban beekeeping, pollen availability, and wild bee species richness. We also found that honey bee abundance had the strongest negative effect on small (inter-tegular span <2.25 mm) wild bee species richness. Small bee species may be at higher risk in areas with abundant honey bee populations as their limited foraging range may reduce their access to floral resources in times of increased competition. Further research on the influence of urban beekeeping on native and wild pollinators, coupled with evidence-based beekeeping regulations, is essential to ensure cities contain sufficient resources to support wild bee diversity alongside managed honey bees.

Do Environmental Cues to Discovery Influence the Likelihood to Rape?

Research on men's sexual exploitation of women has documented that men's psychology tracks cues associated with the ease of women's exploitability. In the current studies, we examined a different class of cues hypothesized to aid men's use of sexually exploitative strategies: environmental cues to the likelihood of discovery. We defined likelihood of discovery as the perceived probability of identification when engaging in exploitative behavior (e.g., presence of others). We test the hypothesis that men's likelihood to rape increases when their perception of the likelihood of discovery is low in three studies. In Study 1, we conducted a content analysis of individuals' responses (N = 1,881) when asked what one would do if they could stop time or be invisible. Besides the "other" category whereby there were no specific category for nominated behaviors, the most nominated category included sexually exploitative behavior-representing 15.3% of reported behaviors. Both Studies 2 (N = 672) and 3 (N = 614) were preregistered manipulations of likelihood of discovery surreptitiously testing men's rape likelihood to rape across varying levels of discovery. We found men, compared to women, reported a statistically higher likelihood to rape in both Studies 2 and 3: 48% compared to 39.7% and 19% compared to 6.8%, respectively. Across Studies 2 and 3, we found no statistical effect of the likelihood of discovery on participants' likelihood to rape. We discuss how the presence of one's peers may provide social protection against the costs of using an exploitative sexual strategy if a perpetrator is caught.

Now or never: Organizational forgetting as a determinant of knowledge sharing and cross-boundary innovation.

This study constructs a theoretical model to test and prove that organizational forgetting influences cross-boundary innovation and testifies to the moderating role of Institutionalized organizational mission in the said relationship. Data was collected through a convenient sampling technique from 353 middle and senior managers of entrepreneurial enterprises in China through online and offline modes. Additionally, we used confirmatory factor analysis, multiple regression, and bootstrap analysis to verify hypotheses using Analysis of a moment structures and Statistical Package for the Social Sciences latest versions. The results show that organizational forgetting has a significantly positive impact on cross-boundary innovation and binary knowledge sharing plays a mediating role in the relationship between organizational forgetting and cross-boundary innovation. Moreover, the mediating effect of exploitative knowledge sharing on the relationship between organizational forgetting and cross-boundary innovation is more substantial than exploratory knowledge sharing. This study separates the impact mechanism of exploitative and exploratory knowledge sharing as a mediator unanimously and proves that Institutionalized organizational mission has a significant moderating role in the relationship between organizational forgetting and cross-boundary innovation. This research offers significant implications for Chinese enterprises to bolster cross-boundary innovation to achieve growth.

Innovation ambidexterity and knowledge redundancy: The moderating effects of transactional leadership.

Entering the challenging and promising knowledge era, it is clear that enterprises should leverage knowledge management activities in improving innovation performance to maintain competitive advantages. This study sheds light on the improvement path of innovation ambidexterity (i.e., exploratory and exploitative innovation) from the perspectives of knowledge redundancy and typical leadership style. It is noted that we determined the research theme through quantitative analysis and conducted qualitative analysis through 209 questionnaire data collected from respondents in different regions and industries in China. The empirical results indicated that knowledge redundancy significantly improves exploratory and exploitative innovation, and transactional leadership negatively moderates the above relationships. This study is of managerial implications to encourage employees to fully master and apply the existing knowledge to strengthen their innovation abilities in value creation. We also contribute to the theories pertaining to knowledge management, innovation, and ambidexterity by providing a deeper understanding of the influencing mechanism of knowledge redundancy in innovation ambidexterity while elaborating on the indirect effects of transactional leadership.

Extending the gleaner-opportunist trade-off.

Species exhibit various trade-offs that can result in stable coexistence of competitors. The gleaner-opportunist trade-off to fluctuations in resource abundance is one of the most intuitive, yet also misunderstood, coexistence-promoting trade-offs. Here, we review its history as an ecological concept, discuss extensions to the classical theory and outline opportunities to advance its understanding. The mechanism of coexistence between species that grow relatively faster than their competitors in a low-resource environment (i.e. a gleaner) versus a high-resource environment (i.e. an opportunist) was first proposed in the 1970s. Stable coexistence could emerge between gleaners and opportunists if the opportunist species (dominant in unstable environments) dampens resource fluctuations via relatively convex functional responses, while the gleaner species (dominant in stable environments) promotes fluctuations, or diminishes them less than the opportunist does, via relatively saturating functional responses. This fluctuation-dependent coexistence mechanism has since been referred to by various names, including the Armstrong-McGehee mechanism and relative nonlinearity of competition. Several researchers have argued this mechanism likely plays a relatively minor role in species coexistence owing in part to the restricted range of conditions that allow it to operate. More recent theoretical research, however, suggests that relative nonlinearity can operate over wider conditions than previously thought. Here, we identify several novel, or little explored, extensions to the gleaner-opportunist trade-off that can yield species coexistence under phenomena as diverse as fluctuations in predation/pathogen pressure, multiple resources, phenotypic plasticity and rapid evolution, amongst other phenomena. While the original definition of the gleaner-opportunist trade-off may be imperfect as a collective for these extensions, we argue that a subtle reframing of the trade-off focusing on species' performance in equilibrium versus fluctuating conditions (irrespective of preferences for high or low resources, predation pressure or other competitive factors) reveals their fundamental commonality in stable coexistence via relative nonlinearity. An extended framing shines a light on the potential ubiquity of this canonical trade-off in nature and on the breadth of theoretical and empirical terrain that remains to be trodden.

Understanding cognitive differences in the effect of digitalization on ambidextrous innovation: Moderating role of industrial knowledge base.

A number of existing researches agree that digitalization would facility firms to launch ambidextrous innovations. Digitalization is not only about technological change, but more importantly, the reshaping of the firms' knowledge structure and routines to percept and integrate knowledge. Thus, some researchers suggest that whether firms could benefit from digitalization varies across firms and industries, since innovation in different firms and industries relies on differentiated level of cognitive and reasoning of knowledge. However, existing studies mainly focus on exploring the firm-level differences, and leave the industry-level difference underdeveloped. In response, this study integrates knowledge-based view to examine how a firm's digitalization affects ambidextrous innovation, and further explore the conjoint effect of industrial knowledge bases-the knowledge base of the industry the firm is located in-on the relationship between firm digitalization level and ambidextrous innovation. This study uses Python to conduct text mining of firms' annual reports, and obtains data of 394 listed companies from the year 2014 to 2020. The empirical results show that digitalization level has positive effect on both exploratory innovation and exploitative innovation, and the effect on exploitative innovation is stronger than on exploratory innovation. Moreover, the moderating effect of industrial knowledge base is significant on "digitalization-exploratory innovation" but not on "digitalization-exploitative innovation" relationship. By doing so, this study refines the research on the relationship between digitalization and firm innovation, and confirms that the usage of digitalization may lead to achieve an ambidextrous situation. This study also provides a theoretical basis for industrial differences of the effectiveness of digitalization, suggesting firms considering industrial characteristics to implement digitalization-assisted innovation practices.

Team idiosyncratic deals and team breakthrough innovation: Based on the perspective of input-process-output model.

Purpose: As a new human resource management practice, idiosyncratic deals are personalized employment arrangements negotiated between employees and employers and intended to benefit them both. It plays an important role in attracting, retaining and motivating employees to promote breakthrough innovation. Based on the input-process-output (I-P-O) model, this paper examines the relationship between team idiosyncratic deals and team breakthrough innovation, the mediating role of team exploratory-exploitative knowledge sharing, and the moderating roles of team transactive memory systems and team cognitive flexibility. Participants and methods: In order to reduce the effects of common method biases and causal lag effect, this study is divided into three stages for data collection, with a time interval of 1 month. Eighty teams (406 employees) from six enterprises in Shanghai and Hangzhou were selected as samples, and the hypothesis test was carried out by hierarchical regression analysis, bootstrap, and Johnson-Neyman method. Results: The results show that higher team idiosyncratic deals are associated with higher team breakthrough innovation through higher team exploratory-exploitative knowledge sharing, and that team transactive memory systems and team cognitive flexibility positively moderate the mediating effect of team exploratory-exploitative knowledge sharing in the relationship between team idiosyncratic deals and team breakthrough innovation in the first stage and the second stage, respectively. Under the joint effect of high team transactive memory systems and high team cognitive flexibility, the mediating effect of team exploratory-exploitative knowledge sharing is stronger. Conclusion: The research results break through the previous research framework of social exchange theory, and I-P-O model to explore the influence mechanism of team idiosyncratic deals, in order to promote the sustainable growth of team breakthrough innovation through this non-standard work arrangement. It is hoped that this research can inspire modern enterprises to create team idiosyncratic deals for valuable teams engaged in breakthrough innovation, which are more conducive to give full play to their heterogeneous talents, and finally help enterprises break through the industry bottleneck and win the market competition.

Carrot and Stick Approach: The Exploitative Leadership and Absenteeism in Education Sector.

Utilizing the conservation of resources theory, this study investigates serial mediation of facades of conformity and depression between exploitative leadership and absenteeism. A total of 211 education sector employees using the convenient sampling technique took part in the survey with data collected in a time-lagged research design. Findings of the study reveal that facades of conformity and depression mediate the independent paths and play a serial mediating role between EL and absenteeism path. This study suggests that EL works as a workplace stressor, under which employees try to protect their valuable resources from further loss in the form of facades of conformity, in doing so, it leads to depression; thus, employees ultimately use absenteeism as an active coping strategy to cope with workplace stressors.

The Curvilinear Relationships Between Relational Embeddedness and Dynamic Capabilities: The Mediating Effect of Ambidextrous Learning.

Dynamic capabilities are crucial to the survival and development of enterprises in the BOP (Base/Bottom of the Pyramid, hereinafter BOP) market. The research focuses on the double-edged sword impact of relational embeddedness on dynamic capabilities via ambidextrous learning, that is moderate embeddedness facilitates dynamic capabilities while overembeddedness inhibits them. Furthermore, this study investigates whether human capital moderates the relationships between relational embeddedness and ambidextrous learning. Selecting 264 samples for empirical research, firstly, the results show that the relational embeddedness in the BOP cooperation network has an inverted U-shaped influence on ambidextrous learning and dynamic capabilities. Secondly, exploratory learning and exploitative learning play a mediating role in relational embeddedness and dynamic capabilities. Thirdly, prior experience plays a positive moderating role in relational embeddedness and exploitative learning. The conclusions facilitate understanding the antecedents of dynamic capabilities and the black box of "embeddedness paradox," and provide empirical evidence for adjusting the human capital of enterprises, enhancing the exploratory learning capability and exploitative learning capability, and coping with the overembeddedness effects.

Platform Leadership and Sustainable Competitive Advantage: The Mediating Role of Ambidextrous Learning.

In the context of the knowledge economy, the role of traditional leadership for enterprises is questioned. Based on contingency theory and the resource-based view, this paper proposes the important role of platform leadership, a new leadership type in line with the context of the times, for a sustainable competitive advantage. We conducted an empirical study to examine and confirm the positive effects of platform leadership on sustainable competitive advantage and ambidextrous learning. We also verified the mediation effect of exploratory and exploitative learning on platform leadership and sustainable competitive advantage. Additionally, relevant discussion and research contributions are put forward.
