Abstract

Purpose

To make the robot that have real autonomous ability is always the goal of mobile robot research. For mobile robots, simultaneous localization and mapping (SLAM) research is no longer satisfied with enabling robots to build maps by remote control, more needs will focus on the autonomous exploration of unknown areas, which refer to the low light, complex spatial features and a series of unstructured environment, lick underground special space (dark and multiintersection). This study aims to propose a novel robot structure with mapping and autonomous exploration algorithms. The experiment proves the detection ability of the robot.

Design/methodology/approach

A small bio-inspired mobile robot suitable for underground special space (dark and multiintersection) is designed, and the control system is set up based on STM32 and Jetson Nano. The robot is equipped with double laser sensor and Ackerman chassis structure, which can adapt to the practical requirements of exploration in underground special space. Based on the graph optimization SLAM method, an optimization method for map construction is proposed. The Iterative Closest Point (ICP) algorithm is used to match two frames of laser to recalculate the relative pose of the robot, which improves the sensor utilization rate of the robot in underground space and also increase the synchronous positioning accuracy. Moreover, based on boundary cells and rapidly-exploring random tree (RRT) algorithm, a new Bio-RRT method for robot autonomous exploration is proposed in addition.

Findings

According to the experimental results, it can be seen that the upgraded SLAM method proposed in this paper achieves better results in map construction. At the same time, the algorithm presents good real-time performance as well as high accuracy and strong maintainability, particularly it can update the map continuously with the passing of time and ensure the positioning accuracy in the process of map updating. The Bio-RRT method fused with the firing excitation mechanism of boundary cells has a more purposeful random tree growth. The number of random tree expansion nodes is less, and the amount of information to be processed is reduced, which leads to the path planning time shorter and the efficiency higher. In addition, the target bias makes the random tree grow directly toward the target point with a certain probability, and the obtained path nodes are basically distributed on or on both sides of the line between the initial point and the target point, which makes the path length shorter and reduces the moving cost of the mobile robot. The final experimental results demonstrate that the proposed upgraded SLAM and Bio-RRT methods can better complete the underground special space exploration task.

Originality/value

Based on the background of robot autonomous exploration in underground special space, a new bio-inspired mobile robot structure with mapping and autonomous exploration algorithm is proposed in this paper. The robot structure is constructed, and the perceptual unit, control unit, driving unit and communication unit are described in detail. The robot can satisfy the practical requirements of exploring the underground dark and multiintersection space. Then, the upgraded graph optimization laser SLAM algorithm and interframe matching optimization method are proposed in this paper. The Bio-RRT independent exploration method is finally proposed, which takes shorter time in equally open space and the search strategy for multiintersection space is more efficient. The experimental results demonstrate that the proposed upgrade SLAM and Bio-RRT methods can better complete the underground space exploration task.

Abstract

Purpose

The purpose of this paper is to analyse the role of quality management on the development of organisational exploration.

Design/methodology/approach

Partial Least Square was used on a sample of 350 companies within the Spanish organic agro-food industry.

Findings

The study results provide empirical evidence of the positive and significant impact that quality management has on the development of organisational exploration.

Research limitations/implications

Causal relationships cannot be applied to this study due to cross-sectional data being used rather than longitudinal data.

Practical implications

Quality management must be considered by managers an essential tool to the development of organisational exploration. As a systematic approach, that moves towards to the development of policies, attitudes and behaviours which foster and boots the development of organisational exploration.

Originality/value

Quality management is a widely used management approach, which organisations use to improve the quality of their products, services and their overall performance. Organisational exploration is seen as a fundamental tool to ensure sustainability, profitability and the future survival of organisations; however, there is disagreement throughout previous research. Some authors point out the importance of quality management in developing activities that promote organisational exploration, whereas other authors see quality management as an inhibitor. Given the great controversy in previous research, our study clarifies the role of quality management in the development of organisational exploration.

Abstract

Purpose

We argue that a fundamental issue regarding how to search and how to switch between different cognitive modes lies in the decision rules that influence the dynamics of learning and exploration. We examine the search logics underlying these decision rules and propose conceptual prompts that can be applied mentally or computationally to aid managers’ decision-making.

Design/methodology/approach

By applying Multi-Armed Bandit (MAB) modeling to simulate agents’ interaction with dynamic environments, we compared the patterns and performance of selected MAB algorithms under different configurations of environmental conditions.

Findings

We develop three conceptual prompts. First, the simple heuristic-based exploration strategy works well in conditions of low environmental variability and few alternatives. Second, an exploration strategy that combines simple and de-biasing heuristics is suitable for most dynamic and complex decision environments. Third, the uncertainty-based exploration strategy is more applicable in the condition of high environmental unpredictability as it can more effectively recognize deviated patterns.

Research limitations/implications

This study contributes to emerging research on using algorithms to develop novel concepts and combining heuristics and algorithmic intelligence in strategic decision-making.

Practical implications

This study offers insights that there are different possibilities for exploration strategies for managers to apply conceptually and that the adaptability of cognitive-distant search may be underestimated in turbulent environments.

Originality/value

Drawing on insights from machine learning and cognitive psychology research, we demonstrate the fitness of different exploration strategies in different dynamic environmental configurations by comparing the different search logics that underlie the three MAB algorithms.

Abstract

Purpose

Organizational exploration has recently emerged in the literature as an essential aspect of contemporary organizations. However, little is known about its antecedents and, specifically, the role of contemporary leadership styles. The present study investigates the relationship between empowering leadership and organizational exploration. In addressing this relationship, we examine preoccupation with failure and leader gender as a mediator and a moderator, respectively.

Design/methodology/approach

We collected data from a sample of 326 US employees in March 2022. To test the present hypotheses, we used the PROCESS SPSS macro.

Findings

Our results supported our moderated mediation model, demonstrating that the indirect relationship of empowering leadership with organizational exploration via preoccupation with failure is stronger for male leaders than for female counterparts.

Practical implications

Concerning the practical implications of this study, organizations should be cognizant of empowering leaders’ impact on desirable outcomes. Additionally, organizations should promote preoccupation with failure to ameliorate organizational exploration. Preoccupation with failure can be achieved when error reporting is encouraged by organizations and supervisors and when a culture that promotes constructive feedback is established.

Originality/value

The present study offers novel insights into the underlying mechanisms and boundary conditions through which empowering leadership relates to organizational exploration. Additionally, it fills a gap in the literature concerning the relationship between empowering leadership and preoccupation with failure. Moreover, it adds to prior research regarding the outcomes of preoccupation with failure, filling the gap regarding the relationship between preoccupation with failure and organizational exploration. Lastly, it expands limited research focused on leader gender as a condition under which the effect of contemporary leadership styles could be enhanced or mitigated.

Abstract

Purpose

Identity exploration is a central mechanism for identity formation that has been found to be associated with intense engagement, positive coping, openness to change, flexible cognition, and meaningful learning. Moreover, identity exploration in school has been associated with adaptive motivation for learning the academic material. Particularly in the fast-changing environment of contemporary society, confidence and skills in identity exploration and self-construction seems to be increasingly important. Therefore, promoting students’ identity exploration in school within the curriculum and in relation to the academic content should be adopted as an important educational goal. The purpose of this paper is to describe a conceptual framework for interventions to promote students’ identity exploration within the curriculum. The framework involves the application of four interrelated principles: (1) promoting self-relevance; (2) triggering exploration; (3) facilitating a sense of safety; and (4) scaffolding exploratory actions.

Approach

We begin the paper with a conceptual review of identity exploration. We follow by specifying the conceptual framework for interventions. We then present a methodological-intervention approach for applying this framework and describe three such interventions in middle-school contexts, in the domains of environmental education, literature, and mathematics.

Findings

In each intervention, applying the principles contributed to students’ adaptive motivation and engagement in the academic material and also contributed to students’ identity exploration, though not among all students. The findings highlight the contextual, dynamic, and indeterminate nature of identity exploration among early adolescents in educational settings, and the utility of the conceptual framework and approach for conceptualizing and intervening to promote identity exploration among students.

Value

This paper contributes to the conceptual understanding of identity exploration in educational settings, highlights the benefits and the challenges in intervening to promote identity exploration among students, and discusses the future directions in theory, research, and practice concerned with the promotion of identity exploration in educational settings.

Abstract

Despite the theoretical assumption that balancing exploration and exploitation is important for long-term performance and survival, previous studies have provided few insights into these relationships because they have focused mainly on the short-term financial performance of organizations. In addition, balancing exploration and exploitation is a critical challenge for small- and medium-sized enterprises (SMEs) that lack the resources, capabilities, and experience necessary to achieving ambidexterity. In this regards, this study empirically explores the relationship between the exploration–exploitation balance and SMEs’ longevity in order to address two important questions from the ambidexterity perspective: (1) How does the balance between exploration and exploitation influence organizational survival? (2) How is the appropriate balance between exploration and exploitation influenced by an organization’s internal and external contexts?

An analysis of 1981–2012 data from the Korean SMEs in IT industry reveals an inverted U-shaped curvilinear relationship between the extent of exploratory innovation and organizational longevity, providing support for the ambidexterity perspective. We further examine the moderating effects of financial slack and environmental dynamism on the relationship between exploratory innovation and organizational longevity. The results indicate that financial slack moderated the exploration–longevity relationship and call for a contingency approach for a better understanding of performance implications of the exploration–exploitation balance.

Abstract

Chapter Summary

This chapter describes public space exploration services’ business goals, purpose, and strategy. It reinforces space exploration organizations’ fundamental bureaucratic administrative culture (Tier 1). The authors describe the influence that political appointees as leaders may play in shaping public sector cultures. Next, the public service culture (Tier 2) is deconstructed, and each of the five layers is described in detail. Additionally, the authors explain why focusing on the beliefs layer is the dominant layer and the essential starting point for analysis in space exploration cultures. Next, the chapter outlines the landscape of external influencing cultures (Tier 3) in the space exploration landscape. Finally, the potential value and challenges of developing internal KLC cultures are explored.

Abstract

The dynamic capabilities perspective focuses on the ability of an organization to develop its resource base in order to meet environmental expectations. Therefore, it is closely interrelated to the issue of managing the interaction of exploration and exploitation. The competence of continuously optimizing the interaction of exploration and exploitation has been referred to as organizational ambidexterity. Managing this interaction implies resolving a firm's permanent struggle to overcome the barriers related to the right configuration between exploration and exploitation.

By incorporating the concept of combinative capabilities as balancing routines into the conceptualization of ambidexterity we distinguish structural, interaction, and socialization capabilities that are deployed in overcoming these barriers to resource (re)configuration.

Drawing on knowledge management and barriers to resource configuration we expect that the way organizations deploy combinative capabilities to manage the interaction between exploration and exploitation depends on the observed barriers to resource (re)configuration. By combining the constructs of barriers to resource reconfiguration, ambidexterity, and combinative capabilities we intend to gain more insight in the way organizations manage the actual interaction between exploration and exploitation. Our paper will introduce a set of propositions indicating the relationship between ambidexterity, barriers to resource (re)configuration, and combinative capabilities as balancing routines.

Abstract

Since March (1991) presented his ideas on organizational learning, hundreds of empirical tests have been conducted on relationships among the activities of exploration, exploitation, ambidexterity, and firm performance. Despite continued interest in his ideas, there has not been a systematic assessment of extant research to reveal whether, and to what extent, these activities relate to firm performance. This study uses meta-analysis to take a next step by aggregating results of 117 studies from more than 21,000 firms. I find strong performance effects for exploration and exploitation, but contrary to received theory, I discover ambidexterity yields weaker effects than a focus on either exploration or exploitation. Thus, I leverage these findings to offer future research opportunities.

Abstract

In this chapter, the authors examine the main effect of entrepreneurial orientation (EO) – a firm’s strategic entrepreneurial posture – on balancing exploration and exploitation in the form of organizational ambidexterity. Resource-constrained firms face an imperative to conduct innovative activities, survive hostile environments, and compete with larger and more resource-rich firms. The authors contend that firms can address these potential impediments through achieving ambidexterity via dynamic capabilities, firm-specific resources, and institutional factors. Specifically, The authors review the EO and ambidexterity literatures and summarize extant arguments related to the relationship between EO, exploration, and exploitation. The authors also discuss the most prominent scales and measures of EO, exploration, and exploitation. Moreover, the authors discuss operationalizational challenges that should be considered when conducting EO–ambidexterity research and suggest future research directions by specifying an agenda outlining useful theoretical perspectives and various contingencies that may influence the EO–ambidexterity relationship.
