Purpose
Although blockchain is often discussed, its actual diffusion seems to be varying for different industries. The purpose of this paper is to explore the blockchain technology diffusion in different industries through a combination of academic literature and social media (Twitter).


Design/methodology/approach
The insights derived from the academic literature and social media have been used to classify industries into five stages of the innovation-decision process, namely, knowledge, persuasion, decision, implementation and confirmation (Rogers, 1995).


Findings
Blockchain is found to be diffused in almost all industries, but the level of diffusion varies. The analysis highlights that manufacturing industry is at the knowledge stage. Further public administration is at persuasion stage. Subsequently, transportation, communications, electric, gas and sanitary services and trading industry had reached to the decision stage. Then, services industries have reached to implementation stage while finance, insurance and real estate industries are the innovators of blockchain technologies and have reached the confirmation stage of innovation-decision process.


Practical implications
Actual implementations of blockchain technology are still in its infancy stage for most of the industries. The findings suggest that specific industries are developing specific blockchain applications.


Originality/value
To the best of the authors' knowledge this is the first study which is using social media data for investigating the diffusion of blockchain in industries. The results show that the combination of Twitter and academic literature analysis gives better insights into diffusion than a single data source.

International audience ; This study tries to address the literature gap of what blockchain can offer to businesses in relation to consumers (B2C), businesses (B2B) and governments (B2G) through systematic literature review on blockchain. The review covers 40 articles from business, management and accounting peer review journals recognized by Scopus database. The review highlights how blockchain will facilitate instant payments, trusted interfaces and traceability of goods for the consumers. Businesses can use blockchain for snapshot sharing, machine-to-machine transactions, accounting, business process management and provenance traceability. Blockchain technology creating new business opportunities in government sector such as digital storage, authentication and maintenance of records; smart trust codification; new market for digital payment services and global commerce.

Part 3: Analytics for Smart Governance ; International audience ; The paper argues for use of Twitter analytics in the study of public policy. Twitter as a social media platform is widely used by many users to express their emotions on various issues. Governments are now realizing the need for social media for administrative purposes and information proliferation to the general public. However, the extent of knowledge among policy makers, about gathering insights from citizen conversations on various social media platforms needs improvement. This research discusses Twitter analytics for two different use cases namely 'Demonetization' and 'GST', where citizen engagement and conversations are monitored, to gain insights. These use cases vary in terms of focus, volume, velocity, veracity, time frame, location, and networked-ness. Possible inferences are presented to gain insights and to help in the policy making process.

PurposeThe importance and criticality of sustainable development goals is witnessed by 195 member countries. For its full-fledged adoption and implementation, it needs to be understood by masses and political leaders are critical agents those engage diverse communities through social media such as twitter. Therefore, in this study focuses on how political leaders can influence the sustainable development goals through Twitter.Design/methodology/approachThis study examines the social media conversations of political leaders on Twitter. Social media analytics methods such as sentiment mining, topic modelling and content analysis-based methods have been used.FindingsThe findings indicate that most political leaders are primarily discussing the sustainable development goals (SDGs) "partnership for goals" and "peace, justice and strong institutions". Many other goals such as "clean water and sanitation", "life below water", "zero hunger", "no poverty" and "educational quality" are not being focused on.Research limitations/implicationsThis study offers implications in terms of collective decision making and the role of policy makers towards the goals of promoting SDGs. The authors highlight how political leaders need to involve key stakeholders in this journey.Originality/valueThis study scores and provides a cohort-specific prioritization of the leadership within these countries with regard to SDGs, which could be beneficial to the society.

Purpose
The purpose of this paper is to summarize the literature of electronic government frameworks and models to identify various constructs and their relationship to measure the performance of e-government projects.


Design/methodology/approach
In total, 77 publications were identified from Scopus database after using exclusion and inclusion criteria. A total of 136 constructs were mapped across five categories. Further using network science, communities of usage of these constructs across different studies were identified.


Findings
Dominant constructs used across studies were ease of use, usefulness, user satisfaction, infrastructure, website maturity, security, user trust, transparency, empowerment, operational efficiency, service quality and information quality. This review offers directions for future research in terms of potential for constructs, which have been explored lesser in the existing literature.


Research limitations/implications
The study provides direction for the usage of theoretical lenses, constructs and association among usage for the evaluation of e-government projects, which have been used less in existing literature, and thus, has higher needs for greater exploration. Search scope is limited to Scopus database, which is one of the largest citation database.


Practical implications
It gives information to the policymakers about the importance of the dominant constructs such as user satisfaction, usefulness, ease of use, efficiency and quality, which have been used across the spectrum of studies of e-government performance assessment frameworks and models. Practitioners need to accommodate the relevance of these factors while designing processes and key performance indicators.


Originality/value
This study analyzes the e-government assessment frameworks and gives direction to theory building for future studies.

The UN COP26 2021 conference on climate change offers the chance for world leaders to take action and make urgent and meaningful commitments to reducing emissions and limit global temperatures to 1.5 °C above pre-industrial levels by 2050. Whilst the political aspects and subsequent ramifications of these fundamental and critical decisions cannot be underestimated, there exists a technical perspective where digital and IS technology has a role to play in the monitoring of potential solutions, but also an integral element of climate change solutions. We explore these aspects in this editorial article, offering a comprehensive opinion based insight to a multitude of diverse viewpoints that look at the many challenges through a technology lens. It is widely recognized that technology in all its forms, is an important and integral element of the solution, but industry and wider society also view technology as being part of the problem. Increasingly, researchers are referencing the importance of responsible digitalization to eliminate the significant levels of e-waste. The reality is that technology is an integral component of the global efforts to get to net zero, however, its adoption requires pragmatic tradeoffs as we transition from current behaviors to a more climate friendly society. ; publishedVersion ; Peer reviewed
