An aspect of spectrum reform receiving increasing attention is the introduction of secondary markets for spectrum in order to enable more flexibility to reassign unused and underused spectrum to users that will use it more efficiently. This paper proposes to focus on the policy issues relating to the development of well‐functioning secondary markets for spectrum.

The paper reviews developments in the debate over secondary markets for spectrum. It draws together key elements from the academic literature, various government and government‐commissioned reports, and the practical experience of the few countries that have already introduced spectrum trading. There is considerable focus on concerns and potential costs relating to the introduction of spectrum trading and liberalisation. This has a constructive aim – to draw attention to the need to address such concerns in order to facilitate the development of spectrum trading.

While there is a persuasive case for spectrum trading, countries have been slow to introduce it because of a number of concerns. This paper identifies these concerns and the regulatory framework/policies needed to address them.

The paper distils the policy issues in the debate over spectrum trading and identifies the role that regulators will need to play in the introduction, facilitation and regulation of secondary markets for spectrum.

This paper aims to propose a procedure to remove international trade barriers globally. Trade is confronting various barriers in the present world, and this is due to the policies of governments to protect interests of their own citizens. Experience shows that trade barriers end up with incurring losses for both sides (traders) in practice, but a look at history of polemics on trade barriers removal in World Trade Organization (WTO) shows that countries are unable to overcome the obstacles they have created. Trade partners understand that removal of counter barriers is advantageous for both parties. In the meantime, being concerned of other party’s response impedes the benefits of free trade for all parties.

This proposition is based upon Islamic Sufism teachings. The propounded principles and goals are in accordance with high understanding of social and economic subtleties of humankind’s life. The authors try to form and formalize Islamic Sufi teachings to establish a base for compiling new international convention that facilitates international trade in all aspects.

To facilitate and promote international trade relations in short run, interested countries may accept a convention to remove all trade barriers among themselves all at once.

The proposed convention does not go against General Agreement on Tariff and Trade and WTO, but it is complementary to both.

The proposed principles are actually shortcuts to what WTO may access in far futures.

Islamic Sufism teachings can lead us to solve current international problems.

WTO has taken important steps to facilitate international trade. To reach the main goal of trade liberalization of WTO, a shortcut solution is proposed here.

The German Chamber of Industry and Commerce in the United Kingdom and the Rheinisch‐Westfälischer Technischer Uberwachungs‐Verein e.V. (RWTUV) (Technical Inspectorate and Information Service) joined forces to make a further contribution towards the promotion of British‐German trade, and have accordingly set up a special information service. In the safety engineering and environmental protection fields, the agreement between these two bodies envisages the provision of information, for both German and British companies, on the applicability of both British and German rules and regulations. To this end, an RWTUV Information Bureau has been set up in partnership with the German Chamber of Industry and Commerce in London. It is at the disposal of all interested companies, and its address is:

The purpose of this paper is to show the link between human error and marine accidents.

The authors carried out field research and also used empirical evidence.

Until 1998, the human side has been neglected, for centuries, in favor of the technical side. Even after 1998 improper focus did not eliminate marine accidents.

Lack of data between human error and marine accidents.

The paper is addressed to the maritime community and its safety administration in the EU and IMO, to eliminate human error.

There is potential for reduction of human injuries, deaths and marine pollution.

The paper is of value as no prior research, in depth, has been done to see what is behind the standard etiquette “human error” in marine accidents.

This paper aims to provide useful information and suggestions for future improvement in relation to China's construction industry and market. With China's rapid economical development and its entry to the World Trade Organization (WTO), much attention has been paid to the China construction business opportunities. However, not much information is available on the history, practices and business cultures of the Chinese construction industry.

Through literature review and interviews with industry professionals, this paper discusses the Chinese construction industry in terms of its market and management practice with a focus on tendering processes, contract management, project on‐site supervision and occupational health and safety (OHS) issues. It also discusses the challenges that face the Chinese construction industry.

China has gone over a long way in construction tendering, contract management and OHS. Its current practice is in the right direction. However, further development and improvements are necessary.

This paper provides useful information to Chinese construction personnel for future improvement. This paper also provides useful information to overseas companies who are planning to enter China's construction market in the near future.

On May 25, 2018, the General Data Protection Regulation (GDPR) became mandatory for all organizations that handle the personal data of European Union citizens. This exploratory study aims to determine the critical success factors (CSFs) related to implementing the GDPR in Portuguese public higher education institutions (HEIs).

This study adopts a multimethod methodology with qualitative and quantitative methods. A multiple case study was carried out in Portuguese public universities. As procedures for data collecting and analysis, semistructured interviews with 26 questions were conducted with the data protection officers of these universities during May and July 2019 to derive a set of CSFs. Next, the Delphi method has been applied to determine the ranking of the CSFs. The hierarchical clusters analysis has also been applied to determine the cluster with essential CSFs. To derive the CSF, the method by Caralli et al. (2004) has been applied.

This study has identified the list of 16 CSFs related to the implementation of GDPR in HEIs, among which we can highlight, for instance, empower workers on the GDPR; commit top management with the GDPR; implement the GDPR with the involvement of management and workers; create a culture for data protection; and create a decentralized team of pivots for data protection.

It could have been more enriching in the CSF determination process if all Portuguese public universities had participated in this study. In fact, within their many similarities, universities are also very different in approaching privacy and data protection. New studies are needed to determine whether the CSFs identified apply equally to other organizations, namely, private HEIs with less bureaucracy.

Identifying CSFs related to GDPR implementation in Portuguese public universities is a new area of study. This paper is a contribution to its development.

The complexity of the construction standards affects the relevance between the system internal elements. Therefore, research on the systematic effect can make the construction activities get the optimum benefit. The purpose of this paper is to discuss these issues.

The research reveals the complex adaptive characteristic of the standard system by using system science theory, analyzes the emergent property mechanism of construction standard system, and provides the mathematical form of the system.

Finally, according to the complex characteristic of standard system, the structure modeling method of complex system is given. This paper provides a new method and theory bases for the construction standard system establishment.

Dynamic, open and non-linear can be considered as the core characteristics of construction standard system in structure, environment and behavior aspects, and that means the standard system is a typical complex system.

The objective of this paper is to draw up management guidelines on environmental sustainability for architectural and engineering design firms.

The paper is derived from a research experience between 2010 and 2018. That experience comes from three source sets: Management Development Program for Design Firms from the Research Line of Management Design, Department of Civil Construction Engineering, University of São Paulo in Brazil; papers including a doctoral thesis; and literature review. Revisiting and investigating processes were conducted by research questions, resulting in lessons learned, management difficulties and guidelines.

The guidelines were drawn up from a strategic sphere, understanding internal and external factors to the firm, diagnosis of the firm's management and sustainability, a building sustainability plan, implications of the plan for management processes, plan monitoring and control and plan evaluation.

The studies were mostly conducted in Brazil, and one of them in the USA. Other studies could be carried out in other countries comparing findings or implementing the guidelines.

The findings will provide feedback to Management Development Program for Design Firms (PDGEP) in the action research method. Moreover, the knowledge about firm's capabilities can advance understanding of architectural and engineering (AE) design firm management as support for sustainability, performance and building information modeling (BIM).

Architectural and engineering design firms are hardly discussed; design is treated in the building project context, giving prominence to technical solutions, not to management ones.

The purpose of the paper is to provide a comprehensive overview of the refurbishment of heritage buildings with special emphasis on sustainability and universal design. Findings of the study are the basis for further research and development of enhanced strategies for retrofitting and adaptive reuse of heritage buildings in the framework of sustainability and universal design.

The present research focusses on literature review analysis of specific elements of the refurbishment of heritage buildings with the aim to discover the characteristics/indicators of sustainability and universal design, which are usually used in refurbishment project and the gaps. In this paper, the latest state-of-art in the mentioned fields has been assessed, and the developments along with research gaps and potential future research focusses have been identified. The literature was collected mainly through Science Direct, World Wide Science and Emerald, especially focussed on publications from 2000 to 2019 written in English and the Web for regulatory and recommendation publications. Other sources, such as actual projects, might shed additional light on the specific issues of the studied topics.

This review shows that the current research related to heritage building renovation and reuse does not address sustainability and universal design issues comprehensively. Typically, in research, the topics of heritage, sustainability and inclusiveness are considered separately. In real situations, however, they are interconnected and influence each other, forming an indivisible whole. The needs of persons with disabilities (PWD) in correlation to the built heritage are not well studied. This is why it is important to consider these topics not only separately but also in an interrelated way.

The need for cross-disciplinary problem-solving method, based on a holistic approach, to form the base for implementation of universal design principles into refurbishing of heritage buildings is seen.

This paper demonstrates the need for usable procedures for various stakeholders in their everyday practice.

The combined subjects of sustainability, heritage buildings and universal design are not well covered by research. Lack of appropriate literature for this specific area is forming a significant gap that hinders the development of relevant information and methods that could be applied in actual projects. This paper, albeit in a partial way, intends to fill this gap and opts to provide a comprehensive summary of the sustainability factors affecting adaptive reuse of heritage buildings with special emphasis on users, specifically PWD.

Media users daily exchange personal data for “free” personalised media. Is this a fair trade, or user “exploitation”? Do personalisation benefits outweigh privacy risks?

This study surveyed experts in three consecutive online rounds (e-Delphi). The authors explored personal data processing value for media, personalisation relevance, benefits and risks for users. The authors scrutinised the value-exchange between media and users and determined whether media communicate transparently, or use “dark patterns” to obtain more personal data.

Communication to users must be clear, correct and concise (prevent user deception). Experts disagree on “payment” with personal data for “free” personalised media. This study discerned obstacles and solutions to substantially balance the interests of media and users (fair value exchange). Personal data processing must be transparent, profitable to media and users. Media can agree “sector-wide” on personalisation transparency. Fair, secure and transparent information disclosure to media is possible through shared responsibility and effort.

This study’s innovative contribution is threefold: Firstly, focus on professional stakeholders’ opinion in the value network. Secondly, recommendations to clearly communicate personalised media value, benefits and risks to users. This allows media to create codes of conduct that increase user trust. Thirdly, expanding literature explaining how media realise personal data value, deal with stakeholder interests and position themselves in the data processing debate. This research improves understanding of personal data value, processing benefits and potential risks in a regional context and European regulatory framework.
