Social Network Analysis

Models and Methods in Social Network Analysis presents the most important developments in quantitative models and methods for analyzing social network data that have appeared during the 1990s. Intended as a complement to Wasserman and Faust’s Social Network Analysis: Methods and Applications, it is a collection of original articles by leading methodologists reviewing recent advances in their particular areas of network methods. Reviewed are advances in network measurement, network sampling, the analysis of centrality, positional analysis or blockmodeling, the analysis of diffusion through networks, the analysis of affiliation or “two-mode” networks, the theory of random graphs, dependence graphs, exponential families of random graphs, the analysis of longitudinal network data, graphic techniques for exploring network data, and software for the analysis of social networks.

Towards product-service system oriented to circular economy: A systematic review of value proposition design approaches

Food choice in transition: adolescent autonomy, agency, and the food environment.

Corporate Social Responsibility (CSR) has been an articulated practice for over 7 decades. Still, most corporations lack an integrated framework to develop a strategic, balanced, and effective approach to achieving excellence in CSR. Considering the world’s critical situation during the COVID-19 pandemic, such a framework is even more crucial now. We suggest subsuming CRS categories under Sustainable Development Goals (SDGs) be used and that they subsume CSR categories since SDGs are a comprehensive agenda designed for the whole planet. This study presents a new CSR drivers model and a novel comprehensive CSR model. Then, it highlights the advantages of integrating CSR and SDGs in a new framework. The proposed framework benefits from both CSR and SDGs, addresses current and future needs, and offers a better roadmap with more measurable outcomes.

Sustainable Development Goals (SDGs) as a Framework for Corporate Social Responsibility (CSR)

The increasing popularity of social media worldwide provides us with an opportunity to understand social, cultural, and environmental issues about people’s perception of sustainability. The article aims at identifying the main topics of communication related to hashtag # sustainability based on a communication analysis on the Twitter network. We investigated the perception of sustainability using data from 414,926 Twitter interactions by 223,476 users worldwide. The data were recorded between April 17, 2018 and July 12, 2019. We identified Innovation, Environment, Climate Change, Corporate Social Responsibility, Technology, and Energy as key hashtags in the field of sustainability. In conjunction with this, we identified the six following communities: (1) Environmental Sustainability, (2) Sustainability Awareness, (3) Renewable Energy and Climate Change, (4) Innovative Technology, (5) Green Architecture, and (6) Food Sustainability. The usage of these communities is applicable in marketing communication as well as in the Corporate Social Responsibility activities of the given companies. The results of the analysis give the organizations a possible direction for their sustainable business model improvement via the contribution of society´s voice.

Twitter Analysis of Global Communication in the Field of Sustainability

Social media allow companies to engage with their interest groups, thus enabling them to solidify corporate social responsibility (CSR) policies. The concept of CSR is now well-established for companies in Western countries, and CSR is becoming an increasingly popular topic in developing countries. This study investigated differences in the perception of the term ‘CSR’ on Instagram between developing and developed countries. We analysed 113,628 Instagram messages from 38,590 unique users worldwide. The data were recorded between 19 November 2017 and 11 December 2018. In both developed and developing countries, charity and social good were common features. On the contrary, a difference was identified in the area of sustainability, which is an important part of communication in developed countries, and the area of education, which is an important part of communication in developing countries. Community analysis revealed four dominant communities in developed countries: (1) philanthropic responsibility, (2) environmental sustainability, (3) pleasure from working and (4) start-ups with CSR; and three in developing countries: (1) social and environmental responsibility, (2) philanthropic responsibility and (3) reputation management. These results could facilitate the strategic management of CSR to adapt communication to local environments and company contexts. Our findings could allow managers to focus CSR activities on relevant issues in developing countries and thus differentiate their CSR communication from competing organizations.

The examined factor areas are based on the creation of a Value Proposition Canvas. Primary data were acquired through the method of questionnaire survey with 217 customers shopping at the farmer's market. The questionnaire	was distributed in person. The most important Customer Jobs are identified as stocking up on fresh and healthy food and feeling good about the purchases; the most important Gain Creators are fresh	and healthy food and the most important Pains are higher prices and inconvenient opening hours. Its results are five general recommendations for market sellers and organizers.

Value Proposition Canvas: Identification of Pains, Gains and Customer Jobs at Farmers' Markets

Social media platforms have become part of many people's lives. Users are spending more and more time on these platforms, creating an active and passive digital footprint through their interaction. This footprint has high research potential in many research areas because understanding people's communication on social media is essential in understanding their values, attitudes, experiences and behaviors. Researchers found that the use of social networking sites impacts adolescents' eating behavior. If we define adolescents as individuals between ages 10 and 24 (WHO's definition), 76% of USA young people at age 18-⁠24 use Instagram, so the Instagram social network analysis is important for understanding young people's expressions in the context of healthy food. This study aims to identify the main topic associated with healthy food on the Instagram social network via hashtag and community analysis based on 2,045,653 messages created by 427,936 individual users. The results show that users most associate Healthy food with healthy lifestyle, fitness, weight loss and diet. In terms of food, these are foods that are Vegan, Homemade, Clean and Plant-based. Given that young people change their behavior in relation to people's behavior on social networks, it is possible to use this data to predict their future association with healthy food characteristics.
