A particular feature that makes foresight powerful is its capability to learn from past trends to help guide decision‐making for future policy. However, in studying both past and future trends, network perspectives are often missing. Since networks are capable of revealing the structure that underpins relationships between stakeholders, key issues and actions in the past, they are powerful to help envisage the future. The purpose of this paper is to propose a methodological framework to incorporate network analysis in foresight.

The paper develops a generic framework to incorporate network analysis into foresight's five stages. Trends identified by respondents of the Big Picture Survey are used to demonstrate how we operationalize this framework.

A network perspective can enrich foresight analysis in that it helps reveal structural linkages between trends and thus can better identify emerging future issues, both of which are critical in foresight.

The inclusion of network analysis can shed light on the process of understanding complex data and assist in building a model based on links and relationships. Network analysis can reveal otherwise unobservable structural features of the data and can help boundary setting discussions in foresight.

Network concepts and measures could usefully enrich the interpretation of foresight data for further analysis, or plausible scenarios.

Network analysis offers a new way of looking at the foresight data by disentangling complicated issue webs. As shaping the future becomes more essential because of the complexity of science, technology and society interrelationships, the incorporation of network perspectives in foresight might be one of the ways to propel future studies.

This paper aims to track how ecotourism has been presented in a digital world over time using geotagged photographs and internet search data. Ecotourism photographs and Google Trends search data are used to evaluate tourist perceptions of ecotourism by developing a categorization of essential attributes, examining the relation of ecotourism and sustainable development, and measuring the popularity of the ecotourism sites.

The researchers collected geotagged photographs from Flickr.com and downloaded Google search data from Google Trends. An integrative approach of content, trend and spatial analysis was applied to develop ecotourism categories and investigate tourist perceptions of ecotourism. First, the authors investigate ecotourism geotagged photographs on a social media to comprehend tourist perceptions of ecotourism by developing a categorization of key ecotourism attributes and measuring the popularity of the ecotourism sites. Second, they examined how ecotourism has been related with sustainable development using internet search data and investigate the trends in search data. Third, spatial analysis using GIS maps was used to visualize the spatial-temporal changes of photographs and tourist views throughout the world.

This study identified three primary themes of ecotourism perceptions and 13 categories of ecotourism attributes. Interest over time about ecotourism was mostly presented as its definitions in Google Trends. The result indicates that tracked ecotourism locations and tourist footprints are not congruent with the popular regions of ecotourism Google search.

This research follows the changing trends in ecotourism over a decade using geotagged photographs and internet search data. The evaluation of the global ecotourism trend provides important insights for global sustainable tourism development and actual tourist perception. Analyzing the trend of ecotourism is a strategic approach to assess the achievement of UN sustainable development goals. Factual perspectives and insights into how tourists are likely to seek and perceive natural attractions are valuable for a range of audiences, such as tourism industries and governments.

The purpose of this paper is to provide a framework for understanding core technological competencies and identifying the trends on the technological convergence of a business ecosystem using the patent information of leading firms in the system.

The proposed framework is composed of two steps: time-sequential text clustering analysis for comprehending changes in general technological fields and association rule analysis for identifying the trends of convergences in each field. The authors applied the proposed framework to the patents applied to United States Patent Trademark Office by Samsung Electronics, a market leader of the electronics industry, during the period from 2000 to 2011.

In the sequential text clustering analysis, trends of 14 technological fields such as data storage medium and data processing, mobile, lights and heats and memory are identified. Moreover, changes of technological convergence in each field are identified using association rule analysis. For instance, in the case of technologies related to lights and heats, convergences occurred between radio transmission systems and modulated-carrier systems during the period from 2000 to 2001. However, recent convergences appeared between technologies regarding controlling lights and liquid crystal materials since 2008.

Utilization of the framework will suggest new business opportunities to SMEs in a business ecosystem by identifying the trends of technological convergences.

The objectives of the study were to demonstrate the suitability of methodology based on a text mining toolset for detecting trends in scientific papers and to find trends that were present in the field of project management during the research time span (2000–2019).

An approach based on text mining tools supported by expert analysis was adopted due to an extensive number of publications in the field of project management. The novelty of the approach lies in the proposed method of trends discovery instead of the commonly used trends predefinition. The use of computer support allowed the full texts of papers, and not only abstracts, to be analysed, which significantly increased the reliability of the achieved results. Overall, 3,544 papers from seven journals were analysed.

As a result, 43 trends were discovered including seven long-lasting, four declining, 17 emerging and 15 ephemeris trends. Trends were analysed in comparison with the results of previous studies and project management frameworks. New trends and potential gaps were discussed.

The results highlight the topics of research that gain popularity among researchers, and which are related to the current problems that arise in project management. Therefore, the results can help focus studies on the most important areas, as well as find new ones which are not so popular yet. The knowledge of current trends is also important for those project managers who seek to improve the efficiency of their work.

The purpose of this paper is to investigate trends in the use of research methodologies and publications in manufacturing strategy (MS) literature across geographical regions and suggests possible future research opportunities.

This literature review is based on a sample of 512 subject-relevant journal articles and uses content analysis as the primary method for data analysis. The paper investigates developments in the use of research methodologies – in terms of research design, data collection methods, country of data collection, sample size, respondent type, statistical techniques used and time horizon of studies; and publication trends in terms of authorship type, authorship collaboration, most prolific authors, top journals, most prolific universities, and citation analysis.

Research in MS has substantially changed from conceptual quantitative to empirical quantitative designs. NA and Europe show a declining research interest. However, other regions of the world are consistently showing higher interest. Significant opportunities and synergies exist for collaborative research among regions.

Though the literature review is limited in its selection of articles and journals it sketches a picture that may surrogate the whole research community in MS.

Trends in publications and use of research methodologies provide directions for designing research projects relevant to various geographical regions. This will help develop a holistic understanding of MS that is meaningful for managers of today’s organizations.

This paper provides broader and deeper review of the MS literature. Complex patterns in data are revealed using cross-tabulations and advanced cross-tabulations that have not been performed in previous content-analysis–based literature reviews in MS. These patterns will help position future research studies.

This study aims to demonstrate the suitability of text-mining toolset for the discovery of trends in quality management (QM) literature in 2000-2019. The hypothesis was formulated that as the field of study is mature, the most important trends are related to deepening and broadening of the knowledge.

A novel approach to trend discovery was proposed. The computer-aided analysis of full-texts of papers led to increased reliability and level of detail of the achieved results and helped significantly reduce researchers’ bias. Overall, 4,833 papers from 8 journal dedicated to QM were analysed.

Trends discovery led to the identification of 45 trends: 17 long-lasting trends, 4 declining trends, 11 emerging trends and 13 ephemeris trends. They were compared to the results of earlier studies. New trends and potential gaps were discussed.

The results highlight the trends that gain or lose popularity, thus they can be used to focus studies, as well as find new subjects, which are not so popular yet. The knowledge about emerging trends is also important for those quality managers who strive for improvement of their efficiency.

The research was designed to bypass the limitations of previous studies. The use of text mining methods and analysis of full texts of papers delivered more detailed and reliable data. Resignation from predefinition of classification criteria significantly reduced researchers’ bias and allowed the discovery of new trends, not identified in previous studies.

The purpose of this paper is to document the total return on investment (ROI) of a comprehensive worksite health program from 1999 to 2007 through two different analytic approaches.

Two analytical techniques were used: time period analysis and historical trend analysis of the entire study period. The time‐period analysis of ROI was performed among employees in four time periods: 1999‐2001; 2002‐2003, 2004‐2005; and 2006‐2007. The historical trend analysis on participation‐related savings was used to compare the financial trend differences between participants and non‐participants as well as the three different participation levels of continuous, sporadic, and non‐participants since the year 2000 among 2,753 employees who worked for and were covered by the company‐sponsored health plans for the entire study period.

The ROI from health care costs and time away from work ranged from 1.29 to 2.07 for the four time periods with a cumulative ROI of 1.66 over nine years. The historical trend analysis of 2,753 long‐term employees resulted in a 1.57 ROI for 2,036 program participants (t‐test: p<0.005) with statistically significant annual saving of $180 per participant per year.

The returns on comprehensive worksite health program were greater than the program investment as documented by both time‐period and historical trend analyses. Organizations seeking ways to manage the increases in health care and absenteeism costs of employees will be encouraged to see that positive returns can be generated by investments in employee health and wellness and steady or consistent participation is one key to generating success.

This paper aims to contribute to the understanding of the concept of a trend and the discourse of trend analysis.

This paper concisely discusses the concept of trends, the value of trend analysis for strategic planning and hierarchical trend pyramids as a tool to scan and analyse trends.

The examples will be given of how specific mega, meso and micro trends are related within a hierarchic trend pyramid.

The tool of trend pyramids helps to structurally analyse and understand trends and developments. Such analysis and understanding are relevant for strategic foresight and scenario planning in leisure and tourism.

The literature on trend levels and pyramids is scarce and varies in interpretation. The aim of this paper is to integrate the various viewpoints into a useful instrument for the scanning and analysis of trends and developments.

The purpose of this paper is to propose and discuss a new regional foresight methodology.

The first part describes the methodology and the organizational process adopted for implementing foresight at the regional level and highlights the criticalities. The research methodology is based on a case study. The case is the analysis of the industrial and regional sectors and the technological families in the Lombardy region.

This methodology analyses trends, technologies and industries, returning a set of qualitative and quantitative indicators. Then, it aggregates them, building two matrixes (trends/technologies and technologies/industries). Finally, it evaluates the future importance of a technology (the attractiveness of a technology for the long-term competitiveness of the regional main industrial sectors) and the capabilities of the regional industrial, technical and scientific system to develop specific technologies (feasibility for the regional system to develop the chosen technology).

The originality lies in an integrated analysis of the possible futures and their relation with the industrial world. Its value is as a tool to suggest policies and R&D investments. It is possible to provide a sound basis for science and technology policymaking.

The purpose of the present study is to analyze highly cited articles and global research emphases and trends of law and psychiatry (L&P) research during the period of 1993 to 2012 from the Web of Science (WOS) database. Besides the analysis of highly cited articles to learn about the classic articles and intellectual base of the L&P research domain, an attempt is made to detect research emphases and trends of the study field.

The present study applies quantitative analyses of citations of scientific publications to find highly cited articles and summarizes research hotspots and trends on L&P research articles from WOS during 1993-2012 using statistical analysis of words in titles, KeyWords Plus, author keywords and co-keywords.

The top 21 highly cited articles of research on L&P were found; most of the highly cited papers used survey research to measure patterns of violence of psychiatric patients. This present study identified forensic psychiatry, mental health and criminal offenders were the continuing mainstream topics in the L&P field and risk assessment, risk factors and risk management of violent behavior, legislation for sexual offences, mental health courts, recidivism and expert testimony were recent research emphases and trends of the study field. On the contrary, psychiatric hospitalization, psychiatrist-patient, community and services were not mainstream topics in the study field and were of decreasing importance and popularity in L&P research. Additionally, the topics of violent behavior and risk assessment have developed to a significant subgroup of L&P research. Finally, research emphases and trends in the L&P field were found based on the co-keywords cluster map and density map.

This is the first study to quantify and detect research emphases and trends in L&P from the WOS during 1993-2012, which may provide the groundwork for future studies of the L&P research domain, and offer some important suggestions and implications for professional researchers, specialists, publications’ editors and public policy makers concerned with the domain.
