Seasonal affective disorder (SAD) is a seasonal pattern modifier to recurrent major depressive disorder. Despite cognitive behavioural therapy (CBT) having a strong evidence base of efficacy for depression, little research exists assessing CBT for SAD, especially in the acute phase of depression during winter months. The aim of this study was to determine the efficacy of CBT for acute SAD in adults. Eligible randomised controlled trials (RCTs) testing the efficacy of CBT on depression symptoms in adults with SAD were included. Depression outcomes were assessed using the Revised Cochrane Risk-of-Bias Tool for Randomized Trials. A meta-analysis using a fixed effects model was conducted to assess the effects of CBT on depression symptoms compared with light therapy (LT) at post-intervention and 1–2 years follow-up. Narrative synthesis was used for recurrence and remission rates. Three RCTs and two follow-up papers met the inclusion criteria. All RCTs measured efficacy of group-CBT for acute SAD and compared to LT. There was substantial variation in risk of bias for all outcomes across the trials. Three RCTs (n=220 participants) were included in the meta-analysis that found CBT was effective in reducing depressive symptoms compared with LT at 1–2-year follow-up post-intervention [MD=–4.5, 95% confidence interval (CI) (–6.88, –2.12), p<0.05]. There was no difference between CBT and LT at immediate post-intervention. Group-CBT appears equivalent to LT in treating acute SAD in adults at post-intervention, but appears more effective at long-term follow-up. The findings should be taken with caution due to few included studies and variation in risk of bias across studies.

Key learning aims

1. (1) Previous research into CBT and seasonal affective disorder has focused primarily on delivery of CBT during the non-acute phase of SAD, typically in non-winter months.

2. (2) There are limited high quality randomised controlled trials testing the efficacy of CBT for seasonal affective disorder in the acute phase during winter months.

3. (3) It appears that group-CBT for SAD is superior to LT at 1–2 years follow-up.

The growing body of literature on corporate purpose has underscored its potential as a strategic driver for firms. However, its practical implementation remains challenging due to the concept’s multifaceted and often abstract nature. By reviewing 118 articles, this systematic literature review develops a process framework on how corporate purpose can be translated into concrete organizational strategies across three dimensions: antecedents, management, and consequences. Specifically, we identify the foundational conditions that shape a purpose statement in firms, examine how purpose is embedded and shared within them, and assess the multilevel outcomes of an effective purpose. The review highlights actionable levers to align purpose with strategy and practice, discussing how firms can implement their ‘reason why’. In doing so, the study provides contributions to better understand corporate purpose from both a theoretical and managerial perspective, within the broader field of strategic management.

The Brazil nut tree Bertholletia excelsa is an icon of Amazon conservation through sustainable use. Moderate disturbance, such as that caused by swidden agriculture, favours this heliophilic species. Our systematic literature review of Bertholletia studies and historical records addresses the following questions: do slash-and-burn farming systems increase Bertholletia density and growth? What do historical records reveal about the links between Bertholletia life history and human occupation? And what policies and regulations shape the current context for harnessing this synergistic potential for sustainable use? Compared to mature forests, slash-and-burn fallow seedling/sapling densities (11–82 individuals ha–1, with a mean of 29 individuals ha–1) are greater and faster-growing. Extant Bertholletia trees that were cut and burned during swidden preparation resprout as forked individuals and supplement new seeds buried by Dasyprocta spp. The presence of large forked Bertholletia trees and the occurrence of anthropogenic soils, particularly brown soils associated with Brazil nut tree groves, provide evidence that extant Bertholletia groves may be islands of active and passive agroecological management by ancestral Indigenous populations and local communities. This supports the notion that conservation through sustainable use can maintain Amazonian megadiversity. Furthermore, fire has been used in the Amazon since the onset of crop cultivation (including Bertholletia) c. 4500 years ago, suggesting that a more effective approach than banning fires would be to implement a systematic and methodical fire and fuel management strategy, given the ineffectiveness of command-and-control policies in this regard. The 124 conservation units and Indigenous lands in the Amazon containing Brazil nut trees reinforce the importance of policies to create protected areas. Evidence suggests that the presence of an Amazonian biocultural forest – a phenomenon resulting from the interaction between human activities and natural processes – can be sustainably used to promote what might be termed ‘sociobiodiversity conservation’.

With China’s economy transitioning into a post-industrial phase focused on knowledge and technology, there has been a notable shift in the patterns of Chinese Outward foreign direct investment (OFDI). This change has led to the emergence of new research perspectives, underscoring the importance of organizing them systematically. To address this, our research presents a thorough analysis of eighty-eight publications examining Chinese OFDI in natural resource-rich (NRR) and technology-intensive (TI) locations across various global regions and countries. Based on the geographical scope and comprehensive coverage of studies published between 1998 and 2023, we summarize the major themes, theories, and methodologies used in this research area. Identifying three elements related to Chinese investment (antecedents and motives, operational strategies, and investment outcomes), we develop a matrix based on the discussion of Chinese firms’ investment behavior in the foreign environment in which they operate. We describe the theoretical distinctions between investments in NRR global regions, such as Africa and Central Asia, and TI regions, such as Europe and North America, with regard to technology acquisition, creation, co-creation, and transfer. We identify several research sub-themes (e.g., control and learning mechanisms, technology transfer, intellectual property, etc.) that remain under-investigated and suggest future research opportunities.

The sharing economy has expanded rapidly, reshaping consumption, labor, and service delivery across sectors. While much research highlights its benefits, critical perspectives on its limitations remain fragmented. This study addresses that gap through a systematic literature review, identifying and categorizing the main drawbacks of the sharing economy across five dimensions: social, legal, technological, economic, and environmental. By synthesizing these critiques into a cohesive framework, the study offers a more comprehensive understanding of the structural challenges associated with sharing economy platforms. It draws on interdisciplinary perspectives to highlight issues such as platform power asymmetries, regulatory gaps, and labor precarity – concerns that have intensified in the wake of the COVID-19 pandemic. The paper contributes to theory by integrating insights across academic domains and to practice by offering targeted recommendations for policymakers and managers. These include differentiated regulation and improved governance strategies to support fairer, more sustainable platform models.

Participation is a prevalent topic in many areas, and data-driven projects are no exception. While the term generally has positive connotations, ambiguities in participatory approaches between facilitators and participants are often noted. However, how facilitators can handle these ambiguities has been less studied. In this paper, we conduct a systematic literature review of participatory data-driven projects. We analyse 27 cases regarding their openness for participation and where participation most often occurs in the data life cycle. From our analysis, we describe three typical project structures of participatory data-driven projects, combining a focus on labour and resource participation and/or rule- and decision-making participation with the general set-up of the project as participatory-informed or participatory-at-core. From these combinations, different ambiguities arise. We discuss mitigations for these ambiguities through project policies and procedures for each type of project. Mitigating and clarifying ambiguities can support a more transparent and problem-oriented application of participatory processes in data-driven projects.

Growing concerns with political polarization have led to a proliferation of research on its consequences. This paper presents results of a systematic literature review and meta-analysis of 25 articles that study the effects of polarization on participation. We categorize studies depending on polarization type (affective or ideological), level (individual or system), and participation type (electoral or non-electoral), to analyze the theoretical arguments proposed by studies in each category. According to a meta-analysis of all 104 coefficients describing the focal effect, individual-level affective and ideological polarization have a positive effect on participation even after publication bias is accounted for. The same analysis finds no evidence of an effect of system-level ideological polarization on election turnout net of publication bias. We conclude with a discussion of the challenges researchers of polarization and participation face, as well as gaps in the extant literature and opportunities for further research on this topic.

Since the 1970s the Swedish government has been promoting social work based on research into methods which work in practice for practitioners and patients. In 2015, the Swedish Agency for Health Technology Assessment (SBU), a government agency instigated in 1987, was commissioned to expand its remit, to review empirical research on social work interventions and to disseminate the results to stakeholders. SBU was then renamed The Swedish Agency for Health Technology Assessment and Assessment of Social Services (SBU). This article describes the fusion of health technology assessment (HTA) and Social Intervention Assessment (SIA), including advantages and challenges.

This systematic literature review paper, written by Channarong Intahchomphoo, Jason Millar, Odd Erik Gundersen, Christian Tschirhart, Kris Meawasige and Hojjat Salemi, examines academic research publications to learn about the effects of artificial intelligence (AI) and robotics on human labour. Papers were collected from three academic databases: Scopus, Web of Science and ABI/INFORM Collection. From 710 papers, 159 papers were included. The article finds that the effects of AI and robotics on human labour can be categorised as: (i) positive effects, (ii) negative effects, and (iii) neutral or unsure effects. The positive effects have five reasons regarding AI and robotics’ potential to: do dangerous work, do tedious work with high efficiency and accuracy, do some aspects of computing work, do work that human labour does not want to do and be used to deal with the labour shortage, and help to reduce business production and maintenance costs. The negative effects are based on two reasons, that AI and robotics will take over human labour in part or entirely, thereby creating unemployment crises, and will not only replace manually repetitive jobs from human labour but also cognitive jobs, causing human labour to fear that their jobs will be replaced by AI and robotics. The neutral and unsure effects are based on various unique arguments. The findings of this review are used to suggest future research for academic communities and practical recommendations to legal professionals and policy makers.

Trade-offs involving multiple criteria that cannot be satisfied at the same time are ubiquitous in engineering design activities. Navigating trade-off decisions can be challenging, especially when it comes to sustainability-related decisions in early-stage projects. Through a systematic literature review, we unravel the challenges related to sustainability trade-offs in technology development, concept design, and other front-end of innovation activities. The challenges, which were evaluated by experts from industry and academia, range from technical and organisational to psychological aspects.

Sustainability is not a new trend, but a mandatory measure for responsible and environmentally conscious use of resources. The digital transformation offers new potential in engineering and competitive advantages for companies through innovative technologies like the digital twin. Based on digital twins, products can be optimized, and new business models can be developed. Long-term added value is generated for manufacturing companies and customers. This paper explores the benefits of digital twins in the context of sustainability. Current challenges and use cases of digital twins are analysed.

The increasing proportion of software in technical products means that both the products and the associated development processes are becoming more complex. An integration of the existing lifecycle considerations Application Lifecycle Management and Product Lifecycle Management into an interdisciplinary System Lifecycle Management promises to make the complexity manageable. To obtain an overview of the current benefits, challenges, requirements, approaches and open research gaps in the context of an ALM-PLM integration, this contribution presents the results of a Systematic Literature Review.

Cruise tourism research has developed exponentially during the past decades. Global tourism activity in general and cruises in particular are concentrated in coastal areas and represent a dominant part of the so-called ‘blue economy’. Within this context, the public debate surrounding the impact of cruise tourism on port communities reflects a narrative of unsustainable growth, environmental pollution and negative globalisation-related symbolism. Yet, the relatively small size of the cruise sector and the over-focus on emissions arguably misrepresents the overall impact and potential of this tourism domain for portside communities, economies and ecosystems. Cruise-related scientific research, as probably expected, offers a much more refined and holistic picture, transcending the somewhat populist public debate on this matter. Based on a systematic literature review examining cruise-related papers published between 1983 and 2009, Papathanassis and Beckmann (2011) Annals of Tourism Research 38(1), 153–174, identified 145 papers, which were subsequently subjected to a metadata- and a thematic-analysis. Approximately, a quarter of them addressed the environmental-, social- and economic impacts of cruising on coastal regions. A decade later, and following an analogous methodological approach, a total of 305 cruise research papers, published between 2012 and 2022, yielded 161 relevant papers, subjected to the same coding scheme and thematically compared to previous findings. The subsequent thematic analysis, revealed a comprehensive set of issues, opportunities and challenges cruise tourism poses to coastal areas. Following a critical discussion of past developments and their trajectory, a future research and action agenda is proposed.

The increasing globalisation, the multiculturality of workplaces and the current challenges for organisations generated the need for researchers to support them to manage the workforce. Although the relevance of employee voice for these themes, a lack of shared understanding about this topic results in fragmented literature across and within research fields that limits theoretical advancement and deep comprehension of the phenomenon. Our first aim is to offer a literature review of employee voice by combining systematic and bibliometric methods; the second aim is to understand voice's main issues and implications by considering different research streams. The results present an integrated framework of the leading intellectual knowledge and reveal the main research focuses on voice in domestic contexts. The discussion underlines the cultural issue and context as critical elements for future research by proposing avenues for scholars and some implications for organisations to benefit from the contributions of their members.

Family firms (FF) represent an important business segment worldwide, contributing greatly to their country's GDP and social well-being, giving employment and contributing to communities' development. Due to their particularities, these organizations also face various challenges, one of the most relevant being inter-generational succession – transversal to all FF and their consequent sustainability over time. Given the importance of this issue, through a systematic literature review (SLR), the intention is to provide a general, wide-ranging view of the succession strategies most used by FF, mapping the existing literature. A total of 84 articles from the Scopus database were analysed. Through content analysis and bibliographic coupling techniques (VosViewer), four thematic groups of articles were identified, namely: (i) socio-emotional wealth and corporate governance, (ii) leadership and inter-generational conflicts, (iii) managing succession process and (iv) succession planning drivers. These themes/clusters originated a theoretical framework that depicts the investigation status of the field, and detailed suggestions for future investigations by cluster were also provided. Despite the relevance and long age of succession in FF, this is the first SLR to directly address succession strategies, offering implications for academics and practitioners, to guide a smooth succession.
