This study examines how narratives and legitimacy formation affect crowdfunding capital assembly from distributed, heterogeneous investors.

The study explores a dataset of 80,181 projects from Kickstarter, a rewards-based crowdfunding platform, between 2009 and 2013. We explore the link between project-related variables, legitimacy formation and outcomes.

Entrepreneurs design narratives and create project legitimacy by exploiting crowdfunding platform-specific features. First, lower funding targets and shorter campaign durations confer positive project legitimacy. Second, entrepreneurs exploit reward-levels as narrative tools that encourage funders to engage with the project. Third, visual pitches transmit a broader sociocultural narrative, leveraging emotional rather than financial reasoning. We also note certain gender effects.

Crowdfunding platforms allow entrepreneurs to pitch business ideas to a broad online audience. We show that project legitimacy, including both structural and narrative elements, is linked to crowdfunding outcomes. In particular, legitimacy is co-created through the generation of a persuasive narrative linking the entrepreneur and investor cohort.

Entrepreneurs use crowdfunding platforms to generate a coherent narrative around unfamiliar business models. Generic platform tools may be set and manipulated in online crowdfunding pitches to support project legitimacy. Ultimately, these are less important than establishing an affinity-based narrative that engages and exploits investor participation. Successful crowdfunding pitches co-author the project story with investors.

Crowdfunding has been traditionally understood as simply an online-mediated venture resource assembly tool. A narrative framework highlights the critical role of legitimacy formation in a disintermediated investment system.

Woodward's seminal research linking technology to optimal organizational form presented a contingent theory of managerial structure that, in effect, presented the organizational version of scientific management. Taylorism addressed individual work processes; Woodward's theory addressed organizational structural processes; deviations from optimized processes or systems reduced effectiveness. The very nature of contingency theory, however, relies on the implicit assumption that the production technology of the organization is the primary mechanism by which the firm generates value. In the case of the biotechnology and social networking firms, the underlying production technology and organizational structure are intermediaries to value creation, not production technologies per se.

Entrepreneurship education has had a remarkable evolution over time and the number of entrepreneurship textbooks has multiplied given the increased interest in entrepreneurship programs in higher education. Yet, studies that review the coverage of textbooks focusing on entrepreneurship are scarce. This study provides an inventory of entrepreneurship textbooks and the topics they cover as well as specific emerging topics they do not cover by analyzing the content of 57 textbooks. Our results suggest that most textbooks provide significant coverage of such topics as the nature of entrepreneurship, business plans, financing, marketing, and cases. Among emerging concepts, social media has been relatively well covered with increasing coverage in more recent textbooks, while business canvas, as an example of alternatives to conventional business plans, is rarely covered. Most textbooks have provided little coverage of such topics as sales, family business, women and minorities, as well as ethics and sustainability. This study not only reveals areas that are covered by existing textbooks but also themes that future textbooks and research could cover to address the challenges of future entrepreneurship education.

Most of the 3D printing machines do not comply with the requirements of on-site, large-scale multi-story building construction. This paper aims to propose the conceptualization of a tower crane (TC)-based 3D printing controlled by artificial intelligence (AI) as the first step towards a large 3D printing development for multi-story buildings. It also aims to overcome the most important limitation of additive manufacturing in the construction industry (the build volume) by exploiting the most important machine used in the field: TCs. It assesses the technology feasibility by investigating the accuracy reached in the printing process.

The research is composed of three main steps: firstly, the TC-based 3D printing concept is defined by proposing an aero-pendulum extruder stabilized by propellers to control the trajectory during the extrusion process; secondly, an AI-based system is defined to control both the crane and the extruder toolpath by exploiting deep reinforcement learning (DRL) control approach; thirdly the proposed framework is validated by simulating the dynamical system and analysing its performance.

The TC-based 3D printer can be effectively used for additive manufacturing in the construction industry. Both the TC and its extruder can be properly controlled by an AI-based control system. The paper shows the effectiveness of the aero-pendulum extruder controlled by AI demonstrated by simulations and validation. The AI-based control system allows for reaching an acceptable tolerance with respect to the ideal trajectory compared with the system tolerance without stabilization.

In related literature, scientific investigations concerning the use of crane systems for 3D printing and AI-based systems for control are completely missing. To the best of the authors’ knowledge, the proposed research demonstrates for the first time the effectiveness of this technology conceptualized and controlled with an intelligent DRL agent.

The results provide the first step towards the development of a new additive manufacturing system for multi-storey constructions exploiting the TC-based 3D printing. The demonstration of the conceptualization feasibility and the control system opens up new possibilities to activate experimental research for companies and research centres.

At a recent meeting of the Glasgow Grocers' and Provision Merchants' Association, it was alleged that there are provision merchants in Glasgow who are doing a large business in selling margarine as butter at 1s. 2d. per pound. In commenting upon this statement The Grocer very properly urges that the officials of the Association referred to should take prompt steps to place the facts in their possession before the Glasgow authorities and their officers, and observes that in certain cities and towns—Birmingham, for example—the grocers' associations have co‐operated with the authorities in their efforts to suppress illegal trading, particularly in regard to the sale of margarine as butter. It appears that one of the members of the Glasgow Association expressed the opinion that the Margarine Act has been a failure and that shopkeepers who sell margarine as butter should be charged with obtaining money under false pretences.
