3D printing technology has the characteristics of fast forming and low cost and can manufacture parts with complex structures. At present, it has been widely used in various manufacturing fields. However, traditional 3-axis printing has limitations of the support structure and step effect due to its low degree of freedom. The purpose of this paper is to propose a robotic 3D printing system that can realize support-free printing of parts with complex structures.

A robotic 3D printing system consisting of a 6-degrees of freedom robotic manipulator with a material extrusion system is proposed for multi-axis additive manufacturing applications. And the authors propose an approximation method for the extrusion value E based on the accumulated arc length of the already printed points, which is used to realize the synchronous movement between multiple systems. Compared with the traditional 3-axis printing system, the proposed robotic 3D printing system can provide greater flexibility when printing complex structures and even realize curved layer printing.

Two printing experiments show that compared with traditional 3D printing, a multi-axis 3D printing system saves 47% and 79% of materials, respectively, and the mechanical properties of curved layer printing using a multi-axis 3D printing system are also better than that of 3-axis printing.

This paper shows a simple and effective method to realize the synchronous movement between multiple systems so as to develop a robotic 3D printing system that can realize support-free printing and verifies the feasibility of the system through experiments.

The purpose of this study is to examine the odious debt concept in Greece. In Greece, the odious debt concept received high attention during recent financial crisis and Greek or Hellenic Parliament decided to establish a Special Committee.

The Greek Parliament Truth Committee on Public Debt investigated the public debt in Greece, and the main findings are: increase of debt was related to the growth in interest payments, high public spending in defence expenditures associated with corruption scandals, falsification of public deficit and debt statistical data and illicit capital outflows and adopting the euro led to a drastic increase in private debt.

Based on above the third Memoranda of Understanding (MoU) and the August 2015 loan agreement, according to Greek Parliament Truth Committee on Public Debt are illegal, illegitimate and odious because they fail to recognize the odious character of Greece’s existing debt, and the nature of the instruments by which this debt was financed from 2010 until early 2015. The Third MoU and the August 2015 loan agreement violate the fundamental human rights of the Greek people (both civil and political as well as socio-economic rights) as set out in the Greek Constitution and under international law (treaty-based and customary).

On the other side of results, Greece was a democratic regime during the time it contracted the vast majority of its loans and membership into the Eurozone, which benefitted country by gaining the highly low interest rates that euro currency involved. Also, substantial borrowing for Greece spent directly on the people via social welfare and public sector wages and infrastructure development.

Therefore, Greece, instead of the odious debt doctrine, should resort to other debt solutions such as simple debt repayment, restructuring or “haircut” of the debt (principal and interest) or declare bankruptcy without invoking the odious debt doctrine. Although this recourse avoids the dangerous precedent-setting risks of the odious debt doctrine, it also involves numerous other complexities and policy problems because with default, the banking system would collapse.

It is the first study examining the topic of odious public debt in Greece.

This paper empirically examines the impact of corporate governance reforms on the financial performance of Indian state-owned enterprises (SOEs) for the period 2003–2011.

The findings indicate that the various corporate governance reforms collectively exhibited a statistically significant positive impact on performance when a difference in difference estimation process is used. However, the performance of SOEs is less than that of publicly listed companies, which is consistent with prior research. When the SOEs are compared with a matched pairing of publicly listed companies of similar size and same industry, their performance was comparable and in many instances superior. This is indicative of the regulatory constraints on competitors and preferential access to resources and markets given to the SOEs. As SOEs move towards a more mixed ownership model with more of them listed on the stock exchange and greater public ownership of shares the corporate governance issues will increase in importance.

The controlled sell down of shares in SOEs presents a need for continuing governance reforms and ongoing research to track progress.

The most striking observation from the study is that changes that were introduced as a corporate governance reform, such greater professionalism in boards, did not gain traction and enhance performance, rather the process of director selection and the concentrated bureaucratic and political interference stymied what was asserted to be conceptually sound reforms.

Debates why and how some practices become universal – taking as a case in point closed‐chest massage (CCCM). Points out that CCCM was recognized in 1960 and its use generated heated debates, which altered the technique and reshuffled existing infrastructures. Claims that debates act as a catalyst for university. Investigates the emergence of CCCM, the debate on the merits (or otherwise) of closed versus open‐chested cardiac massage, and who could use the method of CCCM. Indicates that CCCM only became universally practised when it was incorporated into the infrastructure for dealing with emergency cases, and thus became taken for granted.

The purpose of this paper is to reflect on the journey so far for the North Wales Regional Single Point of Access (SPOA) through the lens of programme manager with views from the programme team. SPOA is the integration of access points to community health and social care services with strengthened links to the third sector, one SPOA in each of six local authorities in the Betsi Cadwallader University Health Board footprint.

Kotter’s 8 step theory of change model (1996) supplemented by the organisational, cultural and professional and contextual factors from research that impact on integrated working between health and social care (Cameron et al., 2012); the focus is programme level.

Kotter’s 8 step model is a useful tool for reflection on the factors identified in research that promote and hinder integrated working. Key messages and innovative ideas of interest for practitioners embarking on a similar “Quest”, including: “keep using your ‘levers for change’”, “Adopt and Adapt”, “right people in the right place”, “it’s ok to tweak your vision, ‘Make it mean something to everyone’, ‘accept and Adapt’, ‘Don’t sweat what you can’t affect’, ‘Find your allies – it’s better together’, ‘Celebrate ‘small wins’’, ‘The people’s voice drives change’ and ‘a sense of humour brings you through’”.

This is a personal reflection from the North Wales Regional SPOA Programme.

It makes use of collaborative work focused on delivering a SPOA, helping others to learn from the struggle.

This study explores whether and how Internet usage improves the subjective health of middle-aged and older adults by analyzing the mediating role of social engagement and heterogeneity of different living arrangements.

Based on data from the China Health and Retirement Longitudinal Study, the ordinary least squares (OLS) method is adopted to explore the relationship between Internet usage and the subjective health of middle-aged and older adults. Propensity score matching method (PSM) is used to alleviate self-selection bias in the samples. The bootstrap method is adopted to test the mediating role of social engagement, and generalized structural equation modeling (GSEM) is employed to resolve endogeneity. A permutation test is adopted to examine the heterogeneous effects of Internet usage on different living arrangements.

Internet access can help relieve depression among middle-aged and older adults and enhance their self-rated health, leading to perceived changes in health status. However, Internet usage is not directly associated with health satisfaction among middle-aged and older adults. Nevertheless, Internet usage can enhance middle-aged and older adults' subjective health by facilitating social engagement and significantly influences middle-aged and older adults living with their children.

This study reveals the underlying role of Internet usage among older adults and provides insights for governments and families to help middle-aged and older adults actively adapt to a digital society and improve their health.

Networks linking tourist attractions or organizations are a major focus of tourism research. Despite extensive research on tourism networks, academic research on the spatial structure and formation of wine tourism networks is limited. This study aims to investigate the spatial structure and factors influencing the development of a network among Ningxia wineries, an emerging wine tourism destination in China.

This study uses social network analysis to uncover “what” the spatial structure of wine tourism networks looks like. Sixteen in-depth interviews were conducted among key stakeholders to explain the “why” of such structural characteristics.

The results show that in an emerging wine tourism destination, popular tourist attractions enjoy high centrality and hold key positions in the wine tourism network. Small wineries exhibit high closeness centrality, and only one winery serves as a network broker. According to the stakeholders, the importance of network actors will increase as their economic and political importance increase, while small wineries that lack differentiation in the network may perish.

Local governments can implement the suggested measures for improving network connections, and wineries are advised to find suitable positions to improve the experiences of tourists.

This study pioneers the identification of the distinct structure and factors influencing the network of an emerging wine tourism destination, thus enriching the understanding of the interplay and roles of different actors.

Traditional Chinese medicine (TCM) had a long history and has been widely practiced worldwide. TCM includes acupunctures, herbal medicine and chiropractic. However, limited studies examined the relationship between knowledge, attitude, utilisation and satisfaction of TCM among the Hong Kong general public. This study has developed a research model which aims to examine the relationship between knowledge, attitude, utilisation and satisfaction of TCM in Hong Kong by using partial least square structural equation model.

An online-based questionnaire was distributed by using convenience sampling. The questionnaire consisted of five parts to collect the data regarding the knowledge, attitude, utilisation and satisfaction of TCM of respondents. The reflective measurement model and structural model were examined with SmartPLS 3.0 statistical software.

A total of 131 respondents completed the survey, and all data were valid after data screening and cleaning. Around 60% of the participants received TCM information from their friends and family members, and 42% from the internet. Likewise, there is positive relationship from the knowledge of TCM to the utilisation, from the attitude to the utilisation and from the utilisation of TCM to the satisfaction. However, the positive relationship of knowledge regarding TCM and attitude is not proven. A t-test and one-way analysis of variance showed no significant differences between gender and age groups on each measurement items.

This paper provides insights for researchers and policymakers to understand the significance of attitude and perception of the benefits of treatments in the use of TCM. The positive experience of TCM from other people is essential for enhancing the willingness to use TCM while education is also fundamental in promoting TCM to the public.

Puts ICANN (Internet Corporation for Assigned Names and Numbers) into a broader political and legal context, and asks whether the new Internet corporation could be seen as a political pilot project which explores the feasibility of a global management and decision‐making system, based on a co‐regulatory model of a “new trilateralism”. Concludes the global knowledge‐based information society is dawning – but nobody can predict the future – the feeling of excitement spreads intangibly.

The purpose of this paper is to explore the corporate social responsibility (CSR) practices of three major professional sport leagues in South Korea to investigate the general beliefs, values, and norms influencing the institutional isomorphism of CSR engagement.

Nine semi-structured interviews were conducted with three league chiefs of CSR initiatives and senior managers of related divisions to explore the general beliefs, values, and norms that are institutionalized in their CSR practices. The Gioia method of inquiry and data analysis was employed.

Using institutional theory, the current research found evidence of all three institutional pressures of institutional isomorphism that contribute to the institutionalization of CSR practices in professional South Korean sport. The data revealed that CSR has been institutionalized in these leagues through isomorphic pressures – coercive, mimetic, and normative – as antecedents to their CSR practices.

The current research identified that conforming to the institutional norms may not only act as a force causing the organization to behave in a socially responsible manner, but also to provide the organization with competitive advantages.

The authors extend the current literature in sport CSR by using institutional theory as a framework to uncover organizational CSR motives. In particular, this is the first study to provide evidence of how three isomorphic pressures work to institutionalize CSR practices in South Korean professional sports leagues.
