Abstract

Purpose

Limited by the types of sensors, the state information available for musculoskeletal robots with highly redundant, nonlinear muscles is often incomplete, which makes the control face a bottleneck problem. The aim of this paper is to design a method to improve the motion performance of musculoskeletal robots in partially observable scenarios, and to leverage the ontology knowledge to enhance the algorithm’s adaptability to musculoskeletal robots that have undergone changes.

Design/methodology/approach

A memory and attention-based reinforcement learning method is proposed for musculoskeletal robots with prior knowledge of muscle synergies. First, to deal with partially observed states available to musculoskeletal robots, a memory and attention-based network architecture is proposed for inferring more sufficient and intrinsic states. Second, inspired by muscle synergy hypothesis in neuroscience, prior knowledge of a musculoskeletal robot’s muscle synergies is embedded in network structure and reward shaping.

Findings

Based on systematic validation, it is found that the proposed method demonstrates superiority over the traditional twin delayed deep deterministic policy gradients (TD3) algorithm. A musculoskeletal robot with highly redundant, nonlinear muscles is adopted to implement goal-directed tasks. In the case of 21-dimensional states, the learning efficiency and accuracy are significantly improved compared with the traditional TD3 algorithm; in the case of 13-dimensional states without velocities and information from the end effector, the traditional TD3 is unable to complete the reaching tasks, while the proposed method breaks through this bottleneck problem.

Originality/value

In this paper, a novel memory and attention-based reinforcement learning method with prior knowledge of muscle synergies is proposed for musculoskeletal robots to deal with partially observable scenarios. Compared with the existing methods, the proposed method effectively improves the performance. Furthermore, this paper promotes the fusion of neuroscience and robotics.

Abstract

In the study of entrepreneurial behavior types, “ambitious entrepreneurship” recently emerged as a new research concept. Unfortunately, a systematic overview of what is known (and not known) about this topic is missing. In particular, insights into the various definitions, measures, and antecedents of ambitious entrepreneurship are lacking. In this chapter, we offer a state-of-the-art review and analysis of extant research on ambitious entrepreneurship. We structure the literature review by providing insights into antecedents of ambitious entrepreneurship, and extensively discuss the conceptualization and operationalization of this research concept. We clarify the differences between related concepts such as growth intention, expectation, and aspiration, and argue how all these concepts fit into a unifying framework of ambitious entrepreneurship. We summarize promising future research avenues for the study of ambitious entrepreneurship, both from a methodological and a conceptual point of view.

Abstract

Within the last two decades, entrepreneurship education has become institutionalized in Germany. It is offered as a stand-alone program or as part of a business degree, combining academic knowledge, practical skills, and personal development to enhance the entrepreneurial success of university graduates. While entrepreneurship education has experienced similar growth worldwide, its emergence in Germany is closely tied to the country’s political and economic developments. The significance of entrepreneurship education for a thriving entrepreneurial ecosystem and contemporary economic policy has been instrumental in advancing its academic recognition. This chapter provides a historical analysis of the academization of entrepreneurship in Germany. It explores the recursive and often idiosyncratic processes involving state and financial institutions, companies, and universities that have created, respecified, and mutually reinforced a subdiscipline and field of study. Academic entrepreneurship knowledge successively not only became relevant for starting a business but also for employment within the entrepreneurial infrastructure and beyond. This chapter follows a chronological order, highlighting three key stages in the academization of entrepreneurship education. First, the academic, financial, and political roots (I) of entrepreneurship up until the 1970s. Second, it explores the transformation (II) of entrepreneurship into a viable policy alternative and the challenges faced in establishing complementary research and education in higher education institutions during the 1980s. Finally, it sketches the institutionalization (III) of entrepreneurship as a central driver of government economic policy, allowing for the late bloom of entrepreneurship education and research at universities around the turn of the millennium.

Abstract

Unlike other populations, entrepreneurs may be unable to fully escape from job-related stress due to their financial and/or psychological connection to their ventures. The authors argue that stress is a universal, intangible variable that profoundly influences the entrepreneurial process. In the present review, the authors critically synthesize past literature to evaluate the substantive body of research on stress in entrepreneurship and assess the impact of stress on individuals’ well-being. The authors find that entrepreneurial stress stems from role conflict or overload, issues related to business operations, and concerns from life outside the venture. Further, stress may result in changes to personal satisfaction and psychological well-being, contingent upon an individual’s stress tolerance, coping strategies, or recovery practices. The entrepreneurial process, from creation to exit, is comprised of several transition periods, all of which are uniquely stressful. The authors explore the implications of our findings by discussing stressors that may manifest during each stage of the entrepreneurial process. Therefore, the authors respond to calls for more dynamic investigation of entrepreneurial stress while also highlighting the need for more research into stressors associated with specific entrepreneurial activities.

Abstract

Purpose

The purpose of this paper is to examine the impact of public policies on engendering entrepreneurship and micro, small, and medium enterprises (MSME) development in Nigeria. Gaps in policies and factors that impede entrepreneurship and MSME development are identified and proposals are offered to address the impediments.

Design/methodology/approach

A thorough review of the mainstream literature on entrepreneurship and MSME development is undertaken. This constitutes the reference point for identifying and reviewing specific public policies formulated and programs designed to stimulate entrepreneurial activities and facilitate MSME development. Data were obtained from federal government agencies. This paper contends that for public policies to accomplish their designed objectives of engendering entrepreneurship and MSME development, strategic realignments of various policy dimensions and programs are imperative.

Findings

Misalignments occur when existing public policies in other domains are in conflict with policies to promote entrepreneurship and MSME development. Policy misalignments negate the profit motive of entrepreneurship; stifle business innovation and expansion; and contribute to survivalist mode of entrepreneurship in the country. This thwarts the public policy goals of creating jobs and alleviating poverty.

Practical implications

Government needs to streamline current regulatory requirements and revamp tax policies to encourage entrepreneurs and MSMEs. Improvements in infrastructure (road networks, highways, power supply, and telecommunications) will significantly reduce overhead costs for entrepreneurs and help MSMEs to grow.

Originality/value

The paper demonstrates that without strategic realignments of public policies to ensure consistency and coherency in various dimensions, efforts to promote entrepreneurship and MSME development will not yield positive results. Existing public policies and programs need to be brought into tight realignment with policies and regulations in other domains to galvanize entrepreneurial efforts.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between bank market power and firm creation, which represents a debated issue in the economic literature, still lacking empirical evidence.

Design/methodology/approach

The analysis is carried out by taking an international perspective, using different measures of banking competition, and controlling for a large set of determinants suggested by the variegate literature on firms’ birth drivers.

Findings

The main finding suggests that credit market competition may benefit firms’ creation, as the relationship between the latter and bank market power – when statistically significant – appears to be negative. In addition, the detrimental impact of market power appears greater (in absolute terms) when departing from higher levels of banking competition.

Research limitations/implications

The empirical evidence seems supporting the competitive position in the debate on the role of banking competition. Furthermore, the authors reckon that the findings reinforce the belief of a crucial role played by the availability of funds for nascent firms, with evident implications for the policy strategies more appropriate to foster entrepreneurship. The “fashion” followed by several countries of lowering administrative entry barriers (van Stel et al., 2007) needs to be reappraised, pondering also means to enrich resources availability.

Originality/value

To the best of the knowledge, the paper is the first one addressing the issue of the role of bank market structure on firms’ creation in a multi-country setting.

Abstract

Entrepreneurship is a prominent area of inquiry which is enriched by an ample literature base and challenged by definitional deficiencies. Over the years, multiple perspectives of entrepreneurship have emerged and a holistic approach to entrepreneurship has been proposed. This can facilitate the continued enlargement of the entrepreneurship field and allow for interdisciplinary research within the African region. This chapter contributes to the literature on entrepreneurship in developing economies by providing an extensive review of the various approaches that entrepreneurship has been conceptualised. Nine themes are explored: the great person, economic perspective, psychological perspective, sociological perspective, behavioural perspective, management, intrapreneurship, cognitive perspective and leadership perspective. This is followed by an examination of entrepreneurship as a process, as a new venture creation and as an art of opportunity recognition and exploitation. In the last section of this chapter, a clarion call is made for more African scholarship and research in the field of entrepreneurship.

Abstract

Although the issues related to the motivation of entrepreneurs have been widely studied, there is a less study focussing on the immigrant women’s entrepreneurial motivation under challenging environment such as COVID-19. Existing studies on entrepreneurs’ motivations mainly adapt the concepts that have often been developed in male-dominated paradigm. According to Shmailan (2016), male entrepreneurs focus on making sure costs are under control and are more profit driven. Women seek to make social contributions and want to ensure their quality. Some of the literature suggests that men are inclined to start businesses because of financial considerations and are more likely to be pulled into entrepreneurship. Conversely, women are likely to start business because of lifestyle issues and are more likely to be pushed into self-employment (Clain, 2000; Georgellis & Wall, 2005; Takahashi, Lourenço, Sander, & Souza, 2014).

This chapter focuses on the motivation of immigrant females in developed economies and what makes them continue especially during difficult times such as recent crisis ‘new normal’, COVID-19 pandemic. The study explores the challenges ethnic female entrepreneurs are facing and what motivated them to continue. The study also seeks their responds and strategies during challenging time such as the pandemic. The findings indicate that women often pursuit business opportunities to satisfy social needs, rather than focussing on traditional business outcomes such as growth or profit. The study found a stronger desire to contribute to a society, community and family’s needs among female founders in the UK . The immigrant female entrepreneurs have shown strong resilience during the COVID-19 pandemic crisis.

Abstract

Purpose

This chapter reviews and critiques the recent evolution of place-based entrepreneurship policy in the United Kingdom, in particular the governance of policies targeted at the regional level to promote economic development and competitiveness. The focus of the chapter is the evolution occurring from 1997, when the Labour government came to power, through to the period leading to the Conservative–Liberal Democrat coalition government, which came to power in 2010.

Methodology/approach

A review and critique of key academic and policy-based literature.

Findings

The chapter shows the way in which governance systems and policies aimed at stimulating entrepreneurship have permeated regional development policy at a number of levels in the United Kingdom. In general, the overarching themes of enterprise policy are similar across the regions, but the difference in governance arrangements demonstrates how emphasis and delivery varies.

Practical implications

Place-based enterprise policy needs long-term commitment, with interventions required to survive changes in approaches to governance if they are to prove effective; something which has been far from the case in recent years. Whilst the analysis is drawn from the case of the United Kingdom, the lessons with regard to the connection between regional modes of governance and effective policy implementation are ones that resonate across other nations that are similarly seeking to stimulate the development of entrepreneurial regions.

Social implications

Evidence of ongoing disparities in regional economic development and competitiveness, linked to differences in regional business culture, suggest the continuance of market failure, whereby leading regions continue to attract resources and stimulate entrepreneurial opportunities at the expense of less competitive regions.

Originality/value of paper

The time period covered by the chapter – 1997 onwards – forms an historic era with regard to changing regional governance and enterprise policy in the United Kingdom, with the emergence – and subsequent demise – of regional development agencies (RDAs) across English regions, as well as the introduction of regional governments in Scotland, Wales and Northern Ireland, which were handed certain powers for economic and enterprise development from the UK central government.
