The aim is to set a state‐of‐the‐art in scientific research towards the development of knee prostheses for transfemoral amputees, by reviewing the literature in the field and by identifying different scientific research lines that have brought out through the years. Also, to provide the information about possible outcomes in the near future, and their links to cybernetics, given the present trends in the field.

Literature related to scientific research carried out up‐to‐date in the field of knee prostheses, is reviewed in scientific articles, books and electronic sources. Then, different research lines are identified from the obtained information, and finally classified as presented in this work.

Three scientific research lines regarding the development of knee prostheses were found, each one dealing with: the design of knee prostheses; the performance assessment of these prostheses; and the creation of control strategies for these prostheses which use electronics to control their performance. Also, two new possible eras of prostheses were encountered: the cybernetic era, and the electromyographic one. Considering both options, it is concluded that the cybernetic era of prostheses is likely to become real soon.

A useful state‐of‐the‐art review for researchers likely to be introduced in the field of development of knee prostheses and prosthetic technology in general.

This literature review not only sets a state‐of‐the‐art of the development of knee prostheses, but also proposes a frame of references which allows to classify the different works done in the field, as well as a better understanding of these through a clear presentation.

High silicon Si–Al alloys (50–70 wt% Si) have been developed by Osprey Metals Ltd for use in electronic packaging. They have the advantages of a coefficient of thermal expansion that can be tailored to match ceramics and electronic materials (6–11 ppm/K), low density (<2.8 g/cm³) high thermal conductivity (>100 W/m K). These alloys are also environmentally friendly and are easy to recycle.These Osprey alloys can be fabricated readily into electronic packages by conventional machining with tungsten‐carbide or polycrystalline diamond (PCD) tools and electro‐discharge machining (EDM). Generally more than one of these conventional machining operations is required in the fabrication process. A new and much faster method has been developed which has been used to produce complete electronic packages from plates of Si–Al alloys in a single machining step. In this novel method, known as thin‐shell electroforming (TSE), an accurate model of the package is produced directly from the drawing in wax using a 3D Systems ThermoJet Modeller. This model is mounted into a frame and it is then plated with a thin copper electroform. The wax model is then melted leaving the electroform attached to the frame. This is backfilled with solder and used as the EDM tool for machining the package from a plate of Si–Al alloy.

We investigate whether active involvement of private equity firms in their portfolio companies during the holding period of a later-stage private equity investment is related to increased levels in operating performance of these companies. Our analysis of unique survey data on 267 European buyouts and secondary performance data on 29 portfolio companies using partial least squares structural equation modeling indicates that private equity firms, that is, their board representatives, can increase operating performance not only by monitoring the behavior of top managers of portfolio companies, but also by becoming involved in strategic decisions and supporting top managers through the provision of strategic resources. Strategic resources, in particular expertise and networks, provided by private equity firm representatives in the form of financial and strategic involvement are associated with increases in the financial performance and competitive prospects of portfolio companies. Operational involvement, however, is not related to changes in operating performance. In addition to empirical insights into the different types of involvement and their effects, this chapter contributes to the buyout literature by providing support for the suggested broadening of the theoretical discussion beyond the dominant perspective of agency theory through developing and testing a complementary resource-based view of involvement. This allows taking into account not only the monitoring, but also the more entrepreneurial supporting element of involvement by private equity firms.

In this chapter, we empirically investigate an important question of “how does knowledge sharing and knowledge leakage impact the alliance performance in dyadic coopetitive alliance settings that involve small- and medium-sized enterprises (SMEs).” Taking the perspective of the focal SME to address this question, we posit that while knowledge sharing positively associates with alliance performance, inadvertent knowledge leakage is negatively related to performance. We further postulate that under the conditions of high knowledge leakage, the positive impacts of knowledge sharing on performance would be reduced. Our structural model results based on a survey of 186 SMEs in the high-tech and knowledge-intensive industries in Sweden show support for two of the hypothesized relationships. More specifically, the results show that knowledge sharing has a positive effect on alliance performance but knowledge leakage has an insignificant direct effect on performance. However, knowledge leakage plays a negative moderating role on the relationship between knowledge sharing and performance. We contribute by demonstrating the effects of knowledge sharing and leakage in under-researched but important dyadic one-to-one coopetitive alliances involving SMEs.

This study aims to review the existing literature on corporate-level strategy to develop a conceptual framework of the headquarters’ roles as well as situational factors influencing them.

The systematic review is conducted. Accordingly, 598 studies (published from 1962–2018) were extracted from three databases (ProQuest, EBSCO and Web of Science). Then, after screening and ensuring the quality by the TAPUPAS checklist, 53 articles were systematically analyzed by manual coding method.

In total, 31 interventions in the form of four roles, namely, “value creation,” “value reduction,” “portfolio management“ and “loss prevent“ were identified for headquarters (HQ). Furthermore, four influencing situational factors distinguish “business characteristics,” “headquarters characteristics,” “corporate company characteristics” and “characteristic of the HQ-subsidiary relationships.”

The value of this research can be outlined as: mapping the cutting edge on the topic and systematizes the current knowledge; presenting an integrative, unique conceptual framework of HQs’ roles and influences, and particularly, of situational factors that determine the consequents of the interventions; and producing practical insights for corporate parent managers considering the situational factors influencing HQs’ roles and influences in managing their business portfolio successfully.

This paper expands theory on strategists by investigating how non-executive strategy professionals in multi-business firms strategize. In focus is the strategizing of two groups of non-executive strategy professionals: a corporate strategy team and eleven business strategists employed in each of the incorporated units.

A case study design was employed to explore privileged accessed data to gain first-hand in-depth qualities of strategists' work. The design was characterized by phenomenon driven immersed participatory insider research with retrospective reflection and theorizing. Data includes strategies, interview data, calendars, meeting minutes, workshop material and observational field notes.

Non-executive strategy professionals in multi-business firms are either employed at the corporate center or in the peripheral businesses. Based on this location and their individual experiences they assume an exclusive content or an inclusive process strategizing orientation. In practice, the groups strategize tightly together.

Case studies are useful in explorative research providing thick descriptions. While empirically rich, the results of this study are limited by the context of one single case. Future research is encouraged to confirm, contradict and refine the results presented.

The insights from this study can help organizations regarding how to employ strategy professionals in multi-business firms.

This paper contributes to a recognized need to explore strategists' work. In contrary to the majority of existing research, focusing on senior management and/or strategy formulation, this paper highlighted non-executive strategy professionals' strategizing.

The purpose of this paper is to explore the role of the digitalization phenomenon in the development of innovative business models that are sustainability oriented. Thus, the authors aim to understand whether the presence of digitalization forces companies to create, capture and deliver value in new ways, focusing on their social impact.

Through the analysis of a case study in the automotive sector, the authors provide evidence that both digitalization and sustainability need to be considered to adequately innovate business models. Moreover, these two dimensions are interrelated, and therefore digitalization sustains sustainability and vice versa.

By inductively investigating the evolutionary path along which companies tend to adapt their business models to digitalization and sustainability trends, the authors found that this innovative transformation needs to be as sustainable as possible in order to offer benefits to organizations, customers and society at large. Furthermore, the authors revealed that, at least in the automotive sector, companies and customers are aware of the remarkable consequences of digitalization; however, they are still uncertain regarding the actual adoption of new technologies.

The literature on business model innovation is quite extensive. However, the role of digitalization in developing sustainable business models to achieve a competitive advantage has been overlooked. This study suggests that, within a specific context, forging a value network of stakeholders is helpful when innovating a business model with a sustainability orientation.

The purpose of this study is to achieve accurate matching of new process cases to historical process cases and then complete the reuse of process knowledge and assembly experience.

By integrating case-based reasoning (CBR) and ontology technology, a multilevel assembly ontology is proposed. Under the general framework, the knowledge of the assembly domain is described hierarchically and associatively. On this basis, an assembly process case matching method is developed.

By fully considering the influence of ontology individual, case structure, assembly scenario and introducing the correction factor, the similarity between non-correlated parts is significantly reduced. Compared with the Triple Matching-Distance Model, the degree of distinction and accuracy of parts matching are effectively improved. Finally, the usefulness of the proposed method is also proved by the matching of four practical assembly cases of precision components.

The process knowledge in historical assembly cases is expressed in a specific ontology framework, which makes up for the defects of the traditional CBR model. The proposed matching method takes into account all aspects of ontology construction and can be used well in cross-ontology similarity calculations.

As a crucial counter-equivalent to business ethics, consumer ethics has emerged as a promising research domain for practitioners and academicians alike. Despite its pertinence for both industry and academia, little is known about the existing state of consumer ethics research. To address this limitation, a systematic literature review was conducted to identify key research themes, gaps in the extant literature and set the agenda for future research.

This literature review is based on a sample of 81 research articles drawn from Scopus and EBSCO host databases and analysed on different classification bases, covering a period from 2004 to 2019.

The results reveal that pro-social behaviour has gained recent attention in consumer ethics research. Moreover, there has been a renewed focus to understand and mitigate the attitude–behaviour gap in ethical consumption. The authors also found that majority of the studies have been conducted in Europe and North America, in a single country context.

Consumer ethics has significant economic and social consequences worldwide. Consumer ethics insights can help marketers and practitioners to devise strategies that minimize business losses due to unethical consumer behaviour, incentivize ethical consumption and align corporate social responsibility initiatives that draw consumer support.

To the best of our knowledge, this is the first major (systematic) review on consumer ethics after Vitell’s review of 2003. This review provides valuable directions for future research to carry this domain forward.

The world revolves around sound. Children who are deaf/hard of hearing (D/HH) lack access to sound, thus need careful monitoring and planning to ensure they have access to adequate language models and supports to develop a strong language foundation. It is this foundation that is needed to ensure D/HH children are able to achieve developmental and academic milestones. Research is emerging to suggest specific intervention strategies that can be used to support D/HH children from birth throughout their educational career. In this chapter, we highlight several strategies that can be used to support communication, language, academic, and social/emotional growth. We freely admit that this is in no way a comprehensive and exhaustive list, but rather only scratches the surface. The field of deaf education and related research and technology is constantly changing. To ensure adequate educational access, it is highly recommended that a professional specialized in hearing loss be a part of the educational team any time a child is identified as having any degree or type of hearing loss.
