This paper introduces a new mathematical model for analyzing the economic benefits of incorporating the fourth party logistics (4PL), which is a contractor (i.e. agent) for the supply chain coordination and construction based on the division of community and the outsourcing development. Based on the physical theory and the wave-particle duality, a supply chain is the special organization whose characteristic has wave-particle duality. The mathematical model enriches the connotation of 4PL and it broadens the thought for 4PL development. Secondly, the proposed mathematical model predicated on transaction costs, is supported by Transaction Cost Theory (TCT) and acts as the theoretical analysis tool of 4PL for coordinating 3-party generic supply chain. Through the model, some trendy conclusions can be drawn to provide theoretical support for 4PL’s practices. Finally, a case illustrates our conclusions.

This chapter presents the current research status of family constitutions from an economics perspective. It locates the family constitution as part of the family and business governance structure of a family firm and the owner family. The typical structure and content of a family constitution are introduced. The chapter focuses on the status of research about family constitutions and provides a structured map for future research. With regard to extant research, it must be stated that the stock of literature is small. The contributions to literature are categorized in surveys; conceptual contributions; survey data; small sample, qualitative, empirical studies; and big sample, quantitative, empirical studies. The latter group includes three studies with a separate family constitution variable. This small number symbolizes that the family constitution still is an under-researched area. Therefore, family constitution research is far away from being able to answer central questions of advice-seeking owner families like, for example, whether a family constitution affects family performance, firm performance, or both; or whether the development process of a family constitutions disposes of an effect on family or firm performance separately from the hypothesized effect of the family constitution document.

Prior family business research has been dominated by an agency theory perspective, narrow definitions of what constitutes family wealth, and a preoccupation with business governance mechanisms to the exclusion of family governance mechanisms. This chapter presents the findings of examining the role of a broader range of governance mechanisms (for the business; for the family) in achieving more comprehensive wealth (economic and non-economic) family business goals in the Australian context. Based on survey responses from around 400 family businesses, the findings from this study show that both family and business governance mechanisms contribute significantly to achieving both the business’s financial performance and the achievement of family-centered goals that are important to the owning family. The results also suggest that the relationship between governance and performance in the family business context is much more complex than that acknowledged in prior research and has implications for both future research and practice.

Videos of police abuse are often spread through technology, raising questions around how perceptions of police are impacted by these images, especially for 18–24-year-olds who are constantly “logged on.” Limited research investigates the impact of social media on attitudes toward police accounting for age and race. The present study utilizes 19 in-depth interviews with a diverse sample of urban college students who regularly use social media in order to understand how they have been impacted by this content. The findings suggest the necessity of using an intersectional framework to understand the impact of tech-witnessed violence. While no gender differences were uncovered, racial differences did surface. White participants described being minimally influenced by videos of police misconduct, rationalizing it as a “few bad apples.” In contrast, participants of color, except those with family members in law enforcement, described being negatively impacted. Viral content contributed to negative opinions of police, emotional distress, and fears of victimization. Ultimately, videos of police brutality do not impact young populations equally. Instead, they are comparatively more harmful to young people of color who spend more time on social media, can envision themselves as the victims, and experience feelings of fear, despair, and anger after watching these videos.

This paper aims to address which resources provided by an entrepreneurial ecosystem (EE) are necessary for deep technology entrepreneurship.

The authors used a novel approach known as necessary condition analysis (NCA) to data on EEs and deep-tech startups from 132 countries, collected in a global innovation index and Crunchbase data sets. The NCA makes it possible to identify whether an EEs resource is a necessary condition that enables entrepreneurship.

Necessary conditions are related to political and business environment; education, research and development; general infrastructure; credit; trade; diversification and market size; and knowledge absorption capacity.

The results show that business and political environments are the most necessary conditions to drive deep-tech entrepreneurship.

Policymakers could prioritize conditions that maximize entrepreneurial output levels rather than focusing on less necessary elements.

Some resources require less performance than others. So, policymakers should consider allocating policy efforts to strengthen resources that maximize output levels.

Studies on deep-tech entrepreneurship are scarce. This study provides a bottleneck analysis that can guide the formulation of policies to support deep-tech entrepreneurship, as it allows to identify priority areas for resource allocation.

From an ethical point of view, the inclusion of children and young people in research is problematic due to their inability to give informed consent and meaningfully express their views. The ethical aspects of research are multiplied if the research participant might have experienced child abuse, neglect, exploitation, or other forms of violence or assisted in such acts. Talking about victimization might be difficult and generate a sense of betrayal of attachment figures. On the other hand, the usual ethical procedure of asking parents or other caretakers to give consent for their children to discuss issues of maltreatment gives them the power to act as gatekeepers to stop children from participating in research. Therefore, researchers should contemplate if parental consent should be waived and how research can be developed to mobilise children's agency and ensure their meaningful cooperation in researching different aspects of violence that affect them. This chapter presents and critically analyses different research examples and discusses their ethical dimensions from a children's rights perspective. The research questions start with discussing the utility of consulting children in research on maltreatment; the gatekeeping role of caregivers; the distress and harm eventually caused to children and young people by participation in research and the benefits of participation for children. The survey examples discussed lead to the conclusions that research on maltreatment might sometimes cause distress; caregivers' power to refuse consent for their children's participation in research on maltreatment can alter epidemiologic data and impede children's right to express their opinion on issues that are central to their lives and therefore, it should be waived; consulting children is essential for collecting data on and improving responses to child maltreatment; and children's contribution to research on maltreatment depends on the adopted methodologies of the research, more advanced forms of participation, and training children to express their opinions, thus enriching scientific knowledge and promoting change.

This study’s goal was to identify how several markets have developed over time and what determinants have influenced this process, based on adaptive markets hypothesis (AMH). In this regard, the authors consider that agents are driven by the seeking for abnormal returns to stay “alive” and their environment could somehow modify their decision-making processes, as well as influence the degree of efficiency of the market.

The authors collected the daily closing-of-the-market index from 50 countries, between 1990 and 2022. The sample includes emerging countries, developed countries and frontier markets. Then, the authors ran multilevel modeling using Hurst exponent as an informational efficiency metric estimated by two different moving windows: 500 and 1,250 observations (approximately 2 and 5 years).

The results indicate that the efficiency of the markets is not constant over time. The authors also have identified that markets follow a cyclical pattern of efficiency/inefficiency, and they are currently in a period of convergence to efficiency, possibly explained by the increase in computational capacity and speed of the available information to agents. In addition, this study identified that country characteristics are associated with market efficiency, considering institutional factors.

Studies of this nature contribute to the literature, considering the importance of better comprehension of market efficiency dynamics and their determinants, specially observing other theories on the relationship between information and markets (like AMH), which work with other investor assumptions than those used by efficient market hypothesis.

This paper aims to print 3D structures from polymers that resist bacterial attachment by reactive jetting of acrylate monomers.

The first step towards printing was ink development. Inks were characterised to carry out an estimation of their potential printability using the Z parameter to predict stable jetting conditions. Printability conditions were optimised for each ink using a Dimatix DMP-2800, which enabled 3D structures to be fabricated.

UV photo-initiated polymers, which resist bacterial attachment, were found to be printable using piezo-based inkjet printers. The waveform required for each ink depends on the value of the Z parameter. Once the waveform and the printability parameters were optimised, 3D objects were fabricated.

This methodology has been confirmed as an effective method to 3D print materials that have been demonstrated to be bacteria resistant. However, ink curing depends on modification of some parameters (such as photoinitiator concentration or UV exposure time) which would result in an improvement of the curing process post jetting.

The combination of inkjet based 3D printing with new materials resistant to bacterial attachment means the possibility of building customised medical devices with a high level of complexity and bespoke features can be fully realised. The scope and variability of the devices produced will exceed what can be achieved using standard fabrication methodologies and can be applied to reduce the incidence of device associated infections and to address increased morbidity, mortality and health care costs associated with nosocomial infections.

In this paper, the novel use of materials that resist bacterial attachment has been described to build 3D structures using material jetting. Its value lies on the potential impact this methodology could produce in the biomedical device and research fields.

In this chapter, the authors outline some of the history of the role of diversity in research and research management, how this has changed and the consequences it has for a workable definition of diversity. We describe the benefits and challenges when working with diversity as research managers and administrators (RMAs) in international research producing organisations (RPOs). The challenges differ in different parts of the world which brings new complexities to navigate. It is shown how the agendas of internationalisation and diversity do not always work well together due to cultural and political perspectives in areas including race, age, gender identity, sexual orientation and other characteristics. The authors suggest how ‘Cultural Intelligence’ (CI) can be used as a frame for RMAs working with diversity and internationalisation both in a pre- and post-award phase and outline some specific steps and initiatives RMAs can take to create equitable and inclusive research and research environments based on their practical experience in the sector.
