Biodegradable polymers are widely used in personalized medical devices or scaffolds for tissue engineering. The manufacturing process should be finished with sterilization procedure. However, it is not clear how the different sterilization methods have an impact on the mechanical strength of the three-dimensional (3D)-printed parts, such as bone models or personalized mechanical devices. This paper aims to present the results of mechanical testing of polylactide-based bone models before and after sterilization.

Polylactide specimens prepared in fused filament fabrication technology were sterilized with different sterilization methods: ultraviolet (UV) and ethylene oxide. Mechanical properties were determined by testing tensile strength, Young’s modulus and toughness.

The tensile strength of material after sterilization was significantly higher after ethylene oxide sterilization compared to the UV sterilization, but in both sterilization methods, the specimens characterized lower tensile strength and Young’s modulus when compared to the control. In comparison of toughness results, there was no statistically significant differences. The findings are particularly significant in the perspective of using individual implants, bone grafts and dental guides.

Although fused filament fabrication (FFF) 3D printing devices equipped with UV light sterilization options are available, experimental results of the effect of selected sterilization methods on the mechanical strength of additively manufactured parts have not been described. This paper completes the present state of the art on the problem of sterilization of FFF parts from biodegradable materials.

Amid public acknowledgment of recurring ethical violations in the volatile financial service industry, internal auditing (IA) professionals do not seem to have done enough to perform their professional responsibility as a line of defense for their employing organizations. This chapter explores whether changes in an IA approach can effectively enable IA as a practice to fulfill its governance role in managing “conduct risk,” i.e., any behavior in a firm that could cause problems to consumer protection, market integrity or competition. We examine the ethical implications of the existing compliance-based IA approach and explain its ineffectiveness in auditing conduct risk within a turbulent environment. Using action research, we explain the germane changes necessary to define a new conduct-focused IA approach capable of predicting and preventing ethical wrongdoing. A conduct-focused approach launches auditors into unfamiliar but strategically critical areas to not only identify material risks but also add value to their organizations. The authors further examine how a change in the auditor’s mindset and other factors promote the effectiveness of the new IA approach in a sustainable way. This chapter contributes to the literature by investigating how internal auditors can better fulfill their professional responsibility when adopting a conduct-focused approach.

The writing of this case study was triggered by the numerous media reports in 2020 that talked about the EU nations losing its solidarity. EU being a very appropriate example of economic, monetary and customs union while teaching theories of economic integration and international relations, the post-pandemic approach of EU leadership to rebuild the crisis-ridden member nations seemed an excellent material for developing a teaching case study.

The case study was written based on secondary data and published information available. Enough desk research was undertaken to build the characterisation of the protagonists and due diligence done to chronologically report all facts of the case as the story developed. It was decided to build the epilogue into the case study so that the case analysis had enough depth.

The case is set in 2020 when the global economy was reeling under the massive impact of a lockdown and the aftermath. The case study examines the model of economic union in international business and the various challenges that governance of an association of nations such as the 27 member EU can throw up. It examines the conflict of interest that can arise among member nations during critical circumstances such as the pandemic and its massive tolls.

EU had established itself as a critical international trade player and had already proven their might as a united entity to the world trade partners, given the fact that they were not only a customs union but also a monetary union. In this scenario when the pandemic threw them into the whirlwind of lockdown-induced crisis, the united front of the mighty EU all but crumbled. As the worst-hit economies of Italy and Spain struggled to pull themselves back to normalcy, EU experienced one of its worst solidarity crises.

EU’s president Angela Merkel and ally French President Emmanuel Macron with support from the EU Council’s President Charles Michel stepped forward to resurrect the badly hit economies. They viewed this as the best opportunity to bring about a united front by coming together at Brussels for a summit when lockdown eased up in July 2020. It was to be a show of unity to jointly bail out the severely affected member nations by grants rather than loans. The summit, however, snowballed into bitter arguments and open bickering between the wealthy and not-so-wealthy members, and they could not agree upon the issue of debt vs aid. The fact that the EU was an agglomeration of 27 nations, which were far from homogenous in socioeconomic status, not to speak of divided political ideologies, only added dimensions to the dispute. Negotiations repeatedly hit roadblocks. Can the EU leaders lead their bitterly divided house to a consensus?

The case is suitable for graduate and post-graduate levels. Management courses where international business studies, international trade blocs and global leadership are part of curriculum can use the case to teach concepts of “Regional economic integration”, “Economic and Political union” and theories of “International relations” and “Negotiation”. It can also be ideally used in an executive management programme on “Global Leadership” to highlight the complexities of “governance of international associations” and “consensus building amidst diversity”.

Parental advocacy is an emerging area of research and policy interest in Wales and across the UK. Although there is little research in the UK context to date, international research has indicated that parental advocacy can improve the relationship between parent and professional in the field of child protection social work. This paper aims to ascertain how the implementation of a parental advocacy programme supports parents to play a meaningful role in decision-making when children’s services are working with them and their families.

This study used interviews, surveys and focus groups to obtain qualitative data from 18 parents, seven parent advocates, two advocacy managers and four social workers, to explore the potential impact of parental advocacy on decision-making. The study identified challenges in implementing parental advocacy, particularly relating to awareness of the service. Participants also discussed experiences of the child protection system and how parents are supported by advocates.

Despite challenges surrounding implementation, initial findings were encouraging, and generated examples of how parental advocacy services have helped parents to understand children’s services and develop relationships of trust with social care professionals. In doing so, this study identified potential mechanisms that may be useful to support future service delivery.

This paper and research is novel as it explores parental advocacy within the Welsh context. Although there has been research conducted into parental advocacy, this has largely come from the USA. This research comes from the evaluation of an innovative and promising parental advocacy scheme in Wales.

The authors investigate how COVID-19 has influenced the amount, type or topics of abuse that UK politicians receive when engaging with the public.

This work covers the first year of COVID-19 in the UK, from March 2020 to March 2021 and analyses Twitter abuse in replies to UK MPs. The authors collected and analysed 17.9 million reply tweets to the MPs. The authors present overall abuse levels during different key moments of the pandemic, analysing reactions to MPs by gender and the relationship between online abuse and topics such as Brexit, the government’s COVID-19 response and policies, and social issues.

The authors have found that abuse levels towards UK MPs were at an all-time high in December 2020. Women (particularly those from non-White backgrounds) receive unusual amounts of abuse, targeting their credibility and capacity to do their jobs. Similar to other large events like general elections and Brexit, COVID-19 has elevated abuse levels, at least temporarily.

Previous studies analysed abuse levels towards MPs in the run-up to the 2017 and 2019 UK General Elections and during the first four months of the COVID-19 pandemic in the UK. The authors compare previous findings with those of the first year of COVID-19, as the pandemic persisted, and Brexit was forthcoming. This research not only contributes to the longitudinal comparison of abuse trends against UK politicians but also presents new findings, corroborates, further clarifies and raises questions about the previous findings.

Nested within institutional theory and the political economy perspective, this study aims to examine Chinese outward foreign direct investments (OFDI)-supporting organizations and fostering mechanisms for its SMEs in Europe’s largest economy, Germany.

The authors conduct a multiple-case study to present rich insights from elite interviews with representatives of Chinese and German governmental organizations, intermediary parties and specialized OFDI consultants. In addition, the authors analyze secondary data such as presentations, websites, brochures, social media and recent Chinese OFDI policies for SMEs. The findings are triangulated by interviewing business owners and senior executives of seven Chinese SMEs that have invested in Germany.

Cooperating with Germany’s federal government, China’s ministries implemented an effective OFDI support network in Germany, which connects and benefits both economies. This includes Chinese governmental organizations, privately-held national champions, German–Chinese business associations and linked intermediary parties. These organizations support SMEs through four main mechanisms: networking and information, mutually beneficial knowledge transfer between innovation partners, lobbying for potential cooperation and an objective picture of Chinese OFDI and facilitating investment services.

This study advances OFDI theory and contributes to the growing discussion on the internationalization of Chinese SMEs by shedding light on China’s OFDI support organizations and mechanisms in the German market. The study also offers practical contributions. Understanding better how governments can spur internationalization is vital, as it determines the effectiveness of policymaking and fosters international mutual understanding, cultural exchange and firm growth and innovation (Ahlstrom, 2010), and hence ultimately contributes positively to society. Moreover, knowing the specific OFDI support organizations and measures China is currently adopting can serve as a helpful orientation for Chinese entrepreneurs who plan to invest in Germany.

Luxury fashion brands have started differentiating their investment strategies and enlarging their sectors of activity, for instance, entering tourism. The overlay between traditional behaviors and innovative strategies has left a mark on the cities and neighborhoods. This chapter explores the spatial distribution of luxury tourism infrastructure in Milan. This transition does not affect only preeminent locations, such as monumental squares and high streets, but also places traditionally excluded from the “luxury circuits.” The location of 5-star hotels and premium tourism facilities in Milan (Michelin restaurants and spas) differ from the general tourism infrastructure. The study identifies polarization in the touristic offer and a parallel influence in the real estate market.

In 2017, it was a challenge to assess the future of global trade. It was an open question whether the US financial crisis and the recession that it triggered would mark a turning point for the liberal post–World War II world order. If one looked toward Europe, China, Latin America, and Japan, there was a flurry of activity. New trade agreements were being completed and pursued. In Washington, DC, on the other hand, President Donald Trump seemed set on ripping apart and/or renegotiating any trade deal the United States was ever part of.

This case explores Trump's opinions and emerging policy stance on trade, bilateralism, and the global economy, among others. It also gives an overview of the World Trade Organization (WTO) and the General Agreement on Tariffs and Trade (GATT) and asks whether the Trump presidency would constitute a major challenge to the WTO and what it stood for in 2017.
