Abstract
Purpose
The aim of this paper is to evaluate the use of blockchain for identity management (IdM) in the context of the Internet of things (IoT) while focusing on privacy-preserving approaches and its applications to healthcare scenarios.
Design/methodology/approach
The paper describes the most relevant IdM systems focusing on privacy preserving with or without blockchain and evaluates them against ten selected features grouped into three categories: privacy, usability and IoT. Then, it is important to analyze whether blockchain should be used in all scenarios, according to the importance of each feature for different use cases.
Findings
Based on analysis of existing systems, Sovrin is the IdM system that covers more features and is based on blockchain. For each of the evaluated use cases, Sovrin and UniquID were the chosen systems.
Research limitations/implications
This paper opens new lines of research for IdM systems in IoT, including challenges related to device identity definition, privacy preserving and new security mechanisms.
Originality/value
This paper contributes to the ongoing research in IdM systems for IoT. The adequacy of blockchain is not only analyzed considering the technology; instead the authors analyze its application to real environments considering the required features for each use case.

Abstract
Purpose
This paper aims to investigate the cultural meanings of excessive drinking in three different countries with different levels of alcohol use chosen as case studies of wider geographies representing Northern (Denmark), Southern (Italy) and Eastern (Estonia) Europe.
Design/methodology/approach
Data were collected according to the Reception Analytical Group Interview method, using video clips as stimuli to enhance comparability. Eight online focus groups were organized in each country for a total number of 128 participants. Symbolic boundaries defining what drinking patterns are socially acceptable were then analysed to look at cross-national variations.
Findings
Results show how different conceptualizations of excessive drinking persist, although a convergence process among drinking patterns is also observed, which suggests that differences mainly depend on meanings and values attributed to intoxication. These are both rooted in the traditional drinking cultures and affected by ongoing social and economic change processes.
Research limitations/implications
Because of the chosen research approach, the research results may lack generalizability, even at country level, as there are differences also within the same drinking culture; however, addressing these differences was beyond the scope of the present study, which aimed to contribute to understanding persisting differences in European drinking culture despite different drivers seem to act for globalization of drinking habits.
Practical implications
The paper includes implications for the development of tailored and effective prevention messages, considering rooted attitudes and cultural values attached to drinking and drunkenness in different European geographies, which are also related to conceptualizations of risks and pleasure.
Originality/value
This paper fulfils an identified need to understand persisting differences in alcohol-related behaviours and outcome in different European countries emerging from quantitative data.

Abstract
Purpose
The purpose of this paper is to analyse dynamics amongst members to better understand in what terms and to what extent marketplace forums can be seen as new forms of harm reduction.
Design/methodology/approach
This is a qualitative analysis focused on conversations about psychoactive substances on the forum community of AlphaBay Market. A sample consists of 100 online threads. The data, collected in July 2016, were analysed by applying the grounded theory approach with the support of Atlas.ti.
Findings
Conversations in the marketplace forum focus mostly on the purchase. Concerns and disputes are voiced in a significant proportion of them, and interactions are affected by a climate of distrust where stigmatisation processes can emerge between users of different drug categories. This casts a certain amount of doubt on the thesis that marketplace forums – like online forums – are new forms of harm reduction and peer-led communities.
Research limitations/implications
The study focuses on only one marketplace forum. Other such forums should be analysed to corroborate its findings.
Practical implications
Harm reduction interventions in the online environment should take different form according to the forum type, and take the differences and boundaries that separate users of different substances into account.
Originality/value
Thanks to its infrequently used qualitative approach, the study provides a more thorough understanding of the relationships on marketplace forums.

Abstract
Purpose – The purpose of this chapter is to retell the narratives of a preservice teacher and a teacher educator as they lived a story of critical literacy and curriculum-making as a curriculum of lives.
Approach – The chapter presents a year-long narrative inquiry centered on the revisioning of curriculum for an undergraduate literacy course for preservice teachers.
Findings – The researcher broadened her understanding of teacher and teacher educators as curriculum makers to include preservice teachers as curriculum makers. As preservice teachers in the literacy course were invited to reflect on their own literacy backgrounds, several crucial narratives emerged that shaped new understandings for the researcher/teacher educator and drew her into her own curriculum-making with moral purpose. One preservice teacher began a journey of narrative authority and curriculum-making as a curriculum of lives in a subsequent field experience, even through the mire of political pressure in schools.
Research implications – The preservice teacher's retelling featured children who discovered newfound understandings of social justice through literary ways of knowing and critical literacy events. She developed new understandings of how to help public school students value and define their literacies and their life events, all of which folded back into the undergraduate literacy course.
Value – Teacher educators can be encouraged to walk in relationship with their preservice teachers, valuing human experiences and lives as curriculum rather than relenting to top-down, politically driven, outside curriculum.

Abstract
Purpose
The purpose of the research is to evaluate the visibility and effectiveness of responsible drinking campaigns used for the sale of the product “beer” (on labels and commercials) on a sample of university students at the University of Pisa to verify whether a preventive “education” on the issue of the effects of alcohol consumption is suitable to improve the perception of responsible communication.
Design/methodology/approach
A focus group methodology was used. Three interviews were conducted with 21 university students. The interview protocol was divided into three sections and ten guiding questions were prepared to conduct the focus groups.
Findings
The study shows the weak effectiveness of responsible communication promoted by brewers, even though the sample knew aspects related to responsible communication and the adverse health effects of alcohol. Most respondents failed to remember the existence of responsibility messages placed on beverage labels, except as a result of visual stimuli, a sign that preventive education can play a role in message recognition. Commercials seem to have a more significant impact when associated with the dangers of drunk driving. However, promoting consumer awareness campaigns continues to be perceived as contradictory.
Originality/value
This study presents the results of qualitative research that focuses on university students' perceptions of the effectiveness of the most recent responsible communication campaigns conducted by brewers. The research is significant in assessing the effectiveness of communication tools, providing theoretical and industrial implications for improving the understanding of the phenomenon and the effectiveness of responsible messages.

Abstract
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract
Purpose
This paper aims to analyze the quality of financial information using financial and economic ratios, assessing if the quality is affected by financial reporting standards. A group of factors that allow proving of the capacity of ratios to measure accounting information quality – and thus facilitating the analysis process to the groups of users – is also determined.
Design/methodology/approach
Using a sample of 111 companies from the Madrid Stock Exchange and 32 from Eurostoxx50, descriptive analysis and non‐parametric variance analysis were carried out during the period 2005‐2007. At the same time, reduction data techniques, specifically principal components analysis (PCA), were performed to detect the underlying main factors for the year 2007.
Findings
There is an indication that financial information quality is affected by financial reporting standards. Additionally, there is a group of factors that show an alternative to analyze accounting information.
Practical implications
This study provides evidence to measure financial information quality and the results can be beneficial to accounting users, as well as contributing to the literature related to this topic.
Originality/value
Empirically, this study shows that accounting information is affected by financial reporting standards.
