Production studies are fundamental for understanding various aspects of the organization and functioning of aquatic systems. The current state of knowledge on this subject is still little explored, especially regarding streams in the Neotropical region. In this study, we present the main theoretical frameworks, the different methods available in the literature, as well as perspectives on the topic for fish from neotropical streams. We emphasize that all available methods lead to similar results and the choice of one or the other falls on the circumstances of the research. For tropical stream fish we recommend using the Size Distribution Method. We also present a step-by-step guide for using the R software (TropFishR package) for production calculations. A comparative approach is carried out for the known production rates in Tropical, Temperate and Mediterranean regions, suggesting an inverse pattern between the species diversity and the production rates of these environments. We hope, with the present study, to stimulate research in this area of knowledge, to include the patterns and processes that generate production in neotropical streams in a broader context of ecological theory.

This paper discusses the creation of an agent-based simulation model for interactive robotic faces, built based on data from physical human–robot interaction experiments, to explore hypotheses around how we might create emergent robotic personality traits, rather than pre-scripted ones based on programmatic rules. If an agent/robot can visually attend and behaviorally respond to social cues in its environment, and that environment varies, then idiosyncratic behavior that forms the basis of what we call a “personality” should theoretically be emergent. Here, we evaluate the stability of behavioral learning convergence in such social environments to test this idea. We conduct over 2000 separate simulations of an agent-based model in scaled-down, abstracted forms of the environment, each one representing an “experiment”, to see how different parameters interact to affect this process. Our findings suggest that there may be systematic dynamics in the learning patterns of an agent/robot in social environments, as well as significant interaction effects between the environmental setup and agent perceptual model. Furthermore, learning from deltas (Markovian approach) was more effective than only considering the current state space. We discuss the implications for HRI research, the design of interactive robotic faces, and the development of more robust theoretical frameworks of social interaction.

Abstract. This paper presents a comparative approach between a digital documentation workflow using contemporary tools versus a traditional documentation technique for Felix Candela's hyperbolic paraboloid (hypar) modern heritage building: Cosmic Rays Pavilion. This documentation was undertaken to better understand the building’s structure, its evolution, and to assess the performance of this concrete structure for future seismic and damage analysis. Furthermore, the paper discusses the challenges related to producing a Heritage Building Information Model (HBIM) of this building using point cloud data in Autodesk’s Revit BIM-authoring software. This project states the importance of a parallel study between the traditional and the contemporary documentation methods; which led to discoveries about the current state of the extrados in the hypar after several earthquakes. Upon analyzing the HBIM and comparing it to the historical drawings, a gap was discovered between the moisture barrier membrane and the concrete shell. Visualizing the building in 3D provides a deeper and more accurate understanding of the current state of this pavilion and is one of many advantages of using digital technologies. The insights provided by digital documentation techniques and analyzing the historical images of the pavilion showed that the curvature of the pavilion has been modified over time. The results imply two hypotheses. First, the curvature profile has been altered due to earthquakes. Second, the modification is due to improper maintenance of the pavilion, namely, multiple additions of the membrane layers. This could not have been detected by solely relying on traditional documentation techniques.

An occupational fatigue risk management system (FRMS) framework can aid practitioners to reduce the fatigue-induced human error, poor performance, and the risk of injury in the industrial settings. However, the current state-of-knowledge on different theoretical frameworks of FRMS adopted in various occupational settings has not been systematically mapped in terms of risk factors, industrial sector types, activity types, and interventions. Therefore, this study aimed to review and characterize the previous literature on FRMS available in the ISI Web of Science (WoS) database and applied various bibliometric approaches to explore current state-of-knowledge, emerging trends and future directions. The data for the analyses were collected from the 68 articles published in 24 various journals between 2001 and 2021. The trend showed a rapid increase in FRMS research in the last seven years, especially in healthcare and aviation industries. Future studies should consider environmental stressors while designing a holistic framework of FRMS.

SummaryKnowledge of ecological patterns and processes is key to effective conservation of biodiversity hotspots under threat. Renosterveld is one of the most critically endangered habitats in the biologically unique Cape Floristic Region, South Africa. For the first time, we map and synthesize the current state of knowledge on renosterveld ecology and conservation. We investigated 132 studies for the themes, locations and taxa of renosterveld research and the fragmentation, threats, recommendations and barriers to renosterveld conservation. More studies focused on plants than any other taxa (48% of articles) and are conducted mostly in larger, intact renosterveld fragments. The most commonly identified threat to renosterveld was agricultural intensification; conservation recommendations spanned improved farming practices, formal protection and local patch management. Conservation implementation has been piecemeal and has depended largely on the goodwill of landowners, which can be constrained by costs of conservation measures and a lack of suitable restoration means. Citizen science is a promising potential solution to some barriers. Fragmented knowledge in such a transformed and relatively densely populated region highlights the scale of knowledge gaps for other biodiversity hotspots and has implications for ongoing conservation work.

Abstract This article uses a comparative approach to analyze the strengths and limitations of the inclusion of religious actors in peace and transition processes. It compares the theoretical frameworks of Bercovitch and Kadayifci-Orellana, and Brewer, demonstrating how the first helps us understand the strengths of religious actors, while the second sheds more light on their limitations. An analysis of the involvement of religious actors in the peace processes in Northern Ireland and Bosnia and Herzegovina supports the argument that religious actors are more likely to contribute to peace when they are excluded from Track One negotiations and are active in other modalities of participation: in wider social peace processes at national or grass-roots levels. Religious actors can contribute to peace processes especially if they choose to exclude themselves from Track One negotiations in order to avoid the pitfalls of becoming too closely associated with political power.

Behavior is a unifying organismal process where genes, neural function, anatomy and environment converge and interrelate. Here we review the current state and discuss the future impact of accelerating advances in technology for behavioral studies, focusing on rodents as an exemplar. We frame our perspective in three dimensions: degree of experimental constraint, dimensionality of data, and level of description. We argue that "big behavioral data" presents challenges proportionate to its promise and describe how these challenges might be met through opportunities afforded by the two rival conceptual legacies of 20th century behavioral science, ethology and psychology. We conclude that although "more is not necessarily better", copious, quantitative and open behavioral data has the potential to transform and unify these two disciplines and to solidify the foundations of others, including neuroscience, but only if the development of novel theoretical frameworks and improved experimental designs matches the technological progress.

The discourse on the writing of national literary histories is still in progress due to the postcolonial and transnational turn. In the frameworks of these literary theories, the meaning of national has been reshaped by focusing on the territorial, ethnic and language borders of contemporary literature. The theory of literary history writing had to face the issues of defining the phenomenon of migrant, emigrant and minority literature. A new Hungarian book titled Kik vagytok ti? Kötelező magyar irodalom – Újraélesztő könyv (Who Are You? Compulsory Hungarian Literature – A Revitalizing Book) (2019), also evoked a debate concerning the theoretical issues of Hungarian literary history writing. In this debate, not only the author and his critics confronted but also the critics with one another. By analysing the critiques and the author’s answers, the fundamental questions of the national literary history writing can be identified. With this metadiscursive approach, I aim to present the current state of Hungarian national literary history writing focusing on the minority and emigrant literature. I will compare the questions generated by the migrant literature in Finland to the issues emerging in the debate about Hungarian literature. This comparative and metadiscursive approach helps to understand the shaping process of the national literature in the dynamics of canonizations and marginalisation.

Technology development has grown rapidly in the last decades and gained importance for accounting and auditing through its identified potentials. Particularly the automation of judgment systems and systems that require human intervention, are deemed to be more relevant to confront a transformation through Robotic Process Automation (RPA). During the continuous development, the augmentation of such systems through Artificial Intelligence (AI) presents a greenfield project with high expectations. However theoretical frameworks have not yet been elaborative and sufficient to capture how such deployments can be conducted. Addressing this research gap, this study presents a summarized overview of the transforming RPA ecosystem and indicates what challenges are critical to being confronted for a successful implementation of such systems in accounting and auditing.

This article analyses the adaptation process from the Danish relationship drama television series ‘Nikolaj and Julie’ (2002–03) to Love Is a Four-Letter Word, the NBC pilot and remake attempt (2015). This comparison is a prime example of autobiographical adaptation, in which the adaptation process can be closely intertwined with a desire to tell autobiographical stories. Using production studies and textual analysis, the article illustrates how Diana Son, the showrunner responsible for adapting the original format into the NBC version, rewrote the original script using a location, themes and characters largely inspired by her personal life and surroundings. The article ultimately argues that in format adaptation, research combining established theoretical frameworks and approaches with the idea of autobiographical adaptation is likely to be a fruitful endeavour in a great many cases.

Purpose – The purpose of this paper is to study the issuance of sustainable development reports by French universities, based on two dimensions proposed by Ansari et al. (2010): extensiveness and fidelity. Design/methodology/approach – Three complementary data sources were used: an extensive literature review, exploratory interviews with sustainable development (SD) officers from French universities, and the four editions of the Responsible Campus Guide (Guide des Campus Responsables). The empirical data collected were then subjected to a dynamic multi-level analysis drawing on three theoretical frameworks. Findings – Four different profiles of universities appear, suggesting that the many isomorphic pressures exerted on universities influence the characteristics (extensiveness and fidelity) of their SD reports. Research limitations/implications – Further research is required to explore whether these findings are generalisable to business schools and universities in different contexts. Practical implications – This study will be of interest to other higher education institutions seeking to embark on a similar sustainability reporting track. It is also a way to observe the characteristics of SD reports, to analyse what and how first-time reporters communicate. Originality/value – This paper adds to existing research by focusing on a managerial innovation that is still relatively new in French universities. Its second contribution lies in its comparative approach introducing a distinction between early and later adopters of SD reporting. It also contributes to extending the existing theorisation of SD reporting.
