This paper aims to perform an exhaustive revision of relevant and recent related studies, which reveals that both extraction methods are currently used to analyze credibility on Twitter. Thus, there is clear evidence of the need of having different options to extract different data for this purpose. Nevertheless, none of these studies perform a comparative evaluation of both extraction techniques. Moreover, the authors extend a previous comparison, which uses a recent developed framework that offers both alternates of data extraction and implements a previously proposed credibility model, by adding a qualitative evaluation and a Twitter-Application Programming Interface (API) performance analysis from different locations.

As one of the most popular social platforms, Twitter has been the focus of recent research aimed at analyzing the credibility of the shared information. To do so, several proposals use either Twitter API or Web scraping to extract the data to perform the analysis. Qualitative and quantitative evaluations are performed to discover the advantages and disadvantages of both extraction methods.

The study demonstrates the differences in terms of accuracy and efficiency of both extraction methods and gives relevance to much more problems related to this area to pursue true transparency and legitimacy of information on the Web.

Results report that some Twitter attributes cannot be retrieved by Web scraping. Both methods produce identical credibility values when a robust normalization process is applied to the text (i.e. tweet). Moreover, concerning the time performance, Web scraping is faster than Twitter API and it is more flexible in terms of obtaining data; however, Web scraping is very sensitive to website changes. Additionally, the response time of the Twitter API is proportional to the distance from the central server at San Francisco.

The purpose of this paper is to present a review of the literature on two lines of research, corporate governance and innovation, explaining how different internal corporate governance mechanisms may be determinants of business innovation.

It explores the theoretical background and the empirical evidence regarding the influence of both ownership structure and the board of directors on company innovation. Then, conclusions are drawn and possible future research lines are presented.

No consensus was observed regarding the relation between corporate governance and innovation, with both positive and negative arguments being found, and with empirical evidence not always pointing in the same direction. Thus, new studies trying to clarify this relationship are needed.

Over recent years, interest has grown in the influence of governance mechanisms on innovation decisions taken by the management. Innovation efforts and results depend on factors that are influenced by corporate governance, such as ownership structure or the functioning of the board of directors. Thus, the paper shows an updated state of the art in this field proposing future lines for empirical research.

This chapter forwards a justification, an explanation, and numerous examples related to an emerging integrated sustainability management theory and its connections to other management theories and key-related concepts including systems and immersion. An integrated approach to sustainability solutions presents several implications for educators, researchers, practitioners, and policymakers, including the need to consider urgent and immediate responses that address sustainability crises at multiple levels and in multiple systems. This chapter is intended to promote reflection, dialogue, and a collective call to action to secure a sustainable world for present and future generations.

This paper aims to propose future public policy guidelines (FPPG) in sustainable regional development for Guaviare (Colombia) – a territory affected by environmental and social distress – for the year 2035.

Following collective action theory and sustainable regional development literature, a foresight exercise was conducted using site focus groups and semi-structured interviews with local participants to identify future strategic change drivers and the most relevant social actors for the attainment of economic, social and environmental development in the Guaviare through FPPG.

The findings suggest that the development of public policies regarding building consensus around Guaviare’s economic, environmental and social issues, reducing conflict between the region’s cultural and environmental ways, decreasing isolation from the centers of decision-making, increasing the transparency of public institutions and reducing insecurity to attract investments are all crucial to attaining sustainable regional development.

Interdisciplinarity is implicit in the local perspectives on the problem that impedes sustainable development in San José del Guaviare. The paper’s main contribution is the long-term vision that breaks away from the traditional short-termism in public policy guidelines in a Latin American context. Methodologically, the significant contribution is the convergent alignment of specific foresight methods toward public policy guidelines’ analysis and design processes.

Recent research in cognitive and social psychology finds that individual change is more emotional than rational. Further evidence suggests that the contagious power of emotions explains how groups may overcome obstacles and behave in unified ways. We offer a neuropsychological model of emotion-driven change in organizations that explains these findings and predicts conditions in which contagion effects will be successful in facilitating rapid change. Our model posits that emotive precursors to conscious action enable goal alignment and overcome cognitive resource limitations necessary to sustain organizational change over time. Our model adapts the findings from social and cognitive neuroscience to bring new insights into the mental mechanisms underlying the change process. The chapter concludes with tentative suggestions for developing new methods for research and practice that improve our predictive capability for creating rapid large-scale organizational change.

This paper sets out to provide a brief guide to brain function and the main causes of brain dysfunction likely to be encountered in social care and neurodisability practice. For the first issue of Social Care and Neurodisability, it was felt that such an overview paper serving both as a self‐contained aide memoire, and as a ‘signpost’ for other relevant resources, would be a useful tool to sit alongside any subsequent articles published in the Journal and provide some relevant brain function context. We have drawn on clinical experience, key references and the growing area of internet‐based resources in order to provide what is hopefully an accessible paper in the spirit of the ubiquitous ‘Made Simple’ series.

Central America is exposed to a variety of natural hazards such as earthquakes, volcanic eruptions, landslides, and floods. The region, located on four connected tectonic plates with 24 active volcanoes and in the path of hurricanes, has experienced 348 major disasters from 1981 to 2010, resulting in 29,007 deaths and US$16.5 billion in direct economic losses. Therefore, all six Central American countries rank among the top 35 countries in the world at high mortality risk from multiple hazards. The countries in this region, including Costa Rica, began paying attention to the disaster risk management (DRM) initiative recently, after Tropical Storm and Hurricane Mitch in 1998, which was the region’s worst catastrophe of the century. After the devastation by Mitch, several local DRM capacity development projects were implemented in the region. By reviewing these project profiles of local DRM implemented in the region, this chapter identifies outcomes, lessons, and challenges of DRM at the local scale, from Mitch to the present, as a baseline for incorporating climate disaster risk reduction into local development planning.

Beyond the rhetoric of Nigeria's policymakers, there are multifaceted challenges threatening sustainable development (SD) in Nigeria under climate change (CC). To strengthen theory and practice, this chapter discusses SD under CC in Nigeria using SWOT analysis. The exploratory focus of this chapter made the qualitative research method, an interpretivist research paradigm, most appropriate. Data sourced from scholarly articles and other secondary resources were reviewed, integrated and synthesised using SWOT analysis. At the end of the SWOT analysis, four insights emerged. The strengths and opportunities of SD under CC include increased awareness and growing access to climate-friendly technologies, sustainable finance, climate-friendly agriculture, solar technologies and renewable energy solutions, among others. The weaknesses and threats include deforestation, unabated gas flaring, rising carbon emissions and exorbitant cost of climate-friendly technologies, among others. The chapter explicates the need for policymakers and regulatory agencies in Nigeria to consolidate the strengths, correct all weaknesses, harness opportunities and avert the looming threats of CC. The chapter contributes to the three themes of SD by affirming that CC comes with devastating consequences that evidently pose existential risks and threats to people, profits and the planet. Consequently, policymakers need to mobilise sufficient resources and capabilities for CC adaptation and mitigation to achieve SD in Nigeria.
