Collaborative hunting in artificial agents with deep reinforcement learning
Authors: Tsutsui Kazushi , Tanaka Ryoya , Takeda Kazuya , Fujii Keisuke 
Published: October 2022

ABSTRACTCollaborative hunting, in which predators play different and complementary roles to capture prey, has been traditionally believed as an advanced hunting strategy requiring large brains that involve high level cognition. However, recent findings that collaborative hunting have also been documented in smaller-brained vertebrates have placed this previous belief under strain. Here, we demonstrate that decisions underlying collaborative hunts do not necessarily rely on sophisticated cognitive processes using computational multi-agent simulation based on deep reinforcement learning. We found that apparently elaborate coordination can be achieved through a relatively simple decision process of mapping between observations and actions via distance-dependent internal representations formed by prior experience. Furthermore, we confirmed that this decision rule of predators is robust against unknown prey controlled by humans. Our results of computational ecology emphasize that collaborative hunting can emerge in various intra- and inter-specific interactions in nature, and provide insights into the evolution of sociality.

AbstractHeat shock promotes the assembly of translation factors into condensates to facilitate the production of stress-protective proteins. How translation factors detect heat and assemble into condensates is not well understood. Here, we investigate heat-induced condensate assembly by the translation factor Ded1p from five different fungi, including Ded1p fromSaccharomyces cerevisiae. Using targeted mutagenesis andin vitroreconstitution biochemistry, we find that heat-induced Ded1p assembly is driven by a conformational rearrangement of the folded helicase domain. This rearrangement determines the assembly temperature and the assembly of Ded1p into nanometer-sized particles, while the flanking intrinsically disordered regions engage in intermolecular interactions to promote assembly into micron-sized condensates. Using protein engineering, we identify six amino acid substitutions that determine most of the thermostability of a thermophilic Ded1p ortholog, thereby providing a molecular understanding underlying the adaptation of the Ded1p assembly temperature to the specific growth temperature of the species. We conclude that heat-induced assembly of Ded1p into translation factor condensates is regulated by a complex interplay of the structured domain and intrinsically disordered regions which is subject to evolutionary tuning.
Towards improving the design and planning of post-conflict housing reconstruction projects: a conceptual framework
Authors: Iskandarani Heba , Proverbs David G. , Xiao Hong 
Published: October 2022

Purpose There is a significant dearth of theoretical and practical knowledge with respect to the design and planning stages of post-conflict housing reconstruction projects. This research presents the development of a conceptual framework towards improving the design and planning processes of post-conflict housing reconstruction projects.Design/methodology/approachA systematic review of the literature on post-conflict housing reconstruction in developing countries, incorporating the themes of collaboration and stakeholder engagement, is presented. A synthesis of this literature is used to inform the development of a conceptual framework that seeks to address the limitations of current housing reconstruction models in post-conflict environments by establishing collaborative approaches at the initial stages of design, as well as the tasks required to achieve efficient results through the aid of relief organisations (NGOs).FindingsWhile the review essentially identifies the fundamental issues and inadequacies of the current housing reconstruction models, the proposed framework aims to enable the implementation of better and efficient collaborative design and planning strategies and practices in post-conflict housing reconstruction.Originality/valueThe conceptual framework aims to promote more effective collaboration through the design of post-conflict housing reconstruction projects by strengthening communication and coordination between the key stakeholders. Furthermore, the research highlights several gaps in the extant literature, signposting new directions for future research in the area of stakeholder engagement during the design and planning post-conflict housing.
The history of knowledge and the history of education
Authors: Barnes Joel , Pietsch Tamson 
Published: October 2022

PurposeThe purpose of this article is to introduce the themed section ofHistory of Education Reviewon “The History of Knowledge and the History of Education”, comprising four empirical articles that together seek to bring the history of education into fuller dialogue with the approaches and methods of the nascent field of the history of knowledge.Design/methodology/approachThis introductory article provides a broad overview of the history of knowledge for the benefit of historians of education, introduces the four themed section articles that follow, and draws out some of their overarching themes and concepts.FindingsThe history of knowledge concept of “arenas of knowledge” emerges as generative across the themed section. Authors also engage with problems of the legitimacy of knowledges, and with pedagogy as practice. In addition, focusing on colonial and postcolonial contexts raises reflexive questions about history of knowledge approaches that have so far largely been developed in European and North American scholarship.Originality/valueThe history of education has not previously been strongly represented among the fields that have gone into the formation of the history of knowledge as a synthetic, interdisciplinary approach to historical studies. Nor have historians of education much engaged with its distinguishing concepts and methodologies. The themed section also extends the history of knowledge itself through its strong focus on colonial and postcolonial histories.
Light-driven mixing strategy inside a nanofluid droplet by asymmetrical Marangoni flow
Authors: Liu Zhe , Wei Hao , Chen Li , Cui Haihang , Sun Bohua 
Published: October 2022

Purpose
The purpose of this study is to establish an effective numerical simulation method to describe the flow pattern and optimize the strategy of noncontact mixing induced by alternating Gaussian light inside a nanofluid droplet and analyzing the influencing factors and flow mechanism of fluid mixing inside a droplet.

Design/methodology/approach
First, the heat converted by the alternating incident Gaussian light acting on the nanoparticles was considered as the bulk heat source distribution, and the equilibrium equation between the surface tension and the viscous force at the upper boundary force was established; then, the numerical simulation methods for multiple-physical-field coupling was established, and the mixing index was used to quantify the mixing degree inside a droplet. The effects of the incident position of alternating Gaussian light and the height of the droplet on the mixing characteristics inside a droplet were studied. Finally, the nondimensional Marangoni number was used to reveal the flow mechanism of the internal mixing of the droplet.

Findings
Noncontact alternating Gaussian light can induce asymmetric vortex motion inside a nanofluid droplet. The incident position of alternating Gaussian light is a significant factor affecting the mixing degree in the droplet. In addition, the heat transfer caused by the surface tension gradient promotes the convection effect, which significantly enhances the mixing of the fluid in the droplet.

Originality/value
This study demonstrates the possibility of the chaotic mixing phenomenon induced by noncontact Gaussian light that occurs within a tiny droplet and provides a feasible method to achieve efficient mixing inside droplets at the microscale.
Will temperature affect the export quality of firms? Evidence from China
Authors: Zhang Junmei , Li Hongyi 
Published: October 2022

Purpose
This study aims to investigate whether temperature affects the product quality of exporters and whether the effect is non-linear. More specifically, whether the impact of high temperatures differs from the impact of low temperatures, and whether different types of companies or industries are affected differently.

Design/methodology/approach
The paper uses detailed data covering all Chinese exporters from 2000 to 2016 to estimate the effects of temperature on the product quality of export firms. To clarify the relationship between them, the authors use a semi-parametric regression method, trying to test whether there is a non-linear relationship between temperature and the export quality of firms.

Findings
The increase in the number of high temperature days significantly reduces the quality of exported products, and this negative effect increases as the temperature rises. High temperature has the most significant negative impact on export quality for firms with low technical complexity, private firms and firms with no intermediate imports and located in historical hot cities. Product quality of both labor-intensive and capital-intensive firms will be affected by heat. High temperatures have the greatest negative impact on the export quality of newly entering products, followed by exiting products, with the least negative impact on persisting product.

Originality/value
To the best of the authors’ knowledge, this paper is the first to examine the impact of temperature on the quality of economic development. The findings of this paper again show that the potential economic impacts of global warming are huge. In addition to some potentially devastating impacts in the future, global warming is already causing imperceptible impacts in the present. Public and economic agents need to fully understand the possible adverse impacts of climate change and take corresponding adaptation measures to cope with global warming.
Multi-attribute group decision-making method with linguistic q-rung orthopair fuzzy information based on bi-direction Choquet integral
Authors: Weng Ling , Lin Jian , Lv Shujie 
Published: October 2022

PurposeThe purpose of this paper is to develop the linguistic q-rung orthopair fuzzy set (LqROFS) information VIKOR method based on the bi-direction Choquet integral (BDCI), taking into account the correlation between information. The method can enrich the existing studies related to LqROFS information and better solve the problem of MAGDM problem.Design/methodology/approachSince applying Choquet integral (CI) depict information interaction is a common operation in MAGDM. However, the traditional CI has some limitations. The unidirectional alignment may affect the MAGDM results. Therefore, a LqROFS-VIKOR method based on BDCI is proposed, where BDCI is used to aggregate the decision matrix. Furthermore, it is not reasonable to apply exact numbers to express the similarity between two qualitative data. Then a new method of defining similarity using linguistics is proposed. The similarity is used to calculate attribute weights.FindingsThe validity and potential application of MAGMD method with linguistic q-rung orthopair fuzzy information based on BDCI are demonstrated in a numerical examples study.Originality/valueAccording to the study of available literature, the current research on LqROFS is incomplete. The existing studies of both similarity and aggregate operators have certain shortcomings. The definition of similarity proposed in this paper is more in line with reality. And compared with the existing methods, the BDCI-based aggregate operator can describe the interaction between information more reasonably. Based on this VIKOR method based on BDCI under the LqROFS environment can better select the alternative.
Risk mitigation effect of foreign debt: evidence from loan pricing
Authors: Chandera Yane 
Published: October 2022

PurposeThe author examines the presence of foreign currency effects and the risk-mitigation channel through which a foreign-currency denomination reduces the loan spread.Design/methodology/approachThe author runs regression analyses using loan data of firms incorporated in member countries of the Association of Southeast Asian Nations (ASEAN) from 2000 to 2020. The author also runs several robustness tests to address forward exchange rate bias, endogeneity concern and sample-selection bias.FindingsConsistent with the currency matching motive of foreign debt use, the results show that a foreign currency denomination is associated with a lower spread and the relationship is amplified when there is a positive correlation between the changes in the return on assets and in the exchange rate.Research limitations/implicationsThis paper enriches existing studies on the use of foreign debt as an exchange rate risk management tool.Practical implicationsThe results suggest that as firms utilize foreign debt and policymakers need to design banking regulations that not only oversee but also encourage the use of foreign debt as a hedging instrument to lower firms' borrowing costs.Originality/valueThis paper contributes to extant studies by examining the presence of foreign currency effects in emerging countries' loan markets and by exploiting the micro-level demand-side factors as the channel through which the currency denomination affects the loan spread.

The metaphor of the journey may help to rethink business models by implementing practices suggested by both marketing and tourism research.
Conceptual research methodology to investigate the relationship between fees and quality of professional service outputs
Authors: Govender Neil , Laryea Samuel , Watermeyer Ron 
Published: October 2022

Purpose
Construction projects require a range of documents (e.g. drawings and specifications) prepared by built environment professionals. In recent years, there has been a perception amongst professionals that quality of documentation has declined. “Low” professional fees were cited as one of the reasons for poor quality documentation. However, most studies on the topic contained inappropriate methodologies. Therefore, the purpose of this paper was to develop a conceptual methodology to comprehensively examine the relationship between fees and professional service output quality.

Design/methodology/approach
A systematic literature review (SLR) was conducted to evaluate the limitations of previous methodologies and identify variables in the relationship between fees and quality of professional service outputs. Findings from the SLR were used to develop a conceptual methodology to investigate the relationship between fees and quality of professional service outputs.

Findings
Based on a frequency analysis of factors in the construction literature, the three main variables influencing professional service output quality were fees, coordination and amount of time available for project tasks. The SLR and shortcomings in previous studies informed the development of a conceptual methodology to examine the relationship between fees and professional service output quality.

Practical implications
The conceptual methodology will assist in comprehensively investigating the effect of fees on the quality of professional service outputs. This is particularly relevant in countries where clients procure built environment professional services based on the lowest fee tendered but are concerned about quality. The methodology can establish how and to what extent “low” fees impact on professional service output quality. Industry professionals can also use variables identified in this paper to mitigate quality-related risks when producing professional service outputs.

Originality/value
This paper adds to the body of knowledge by identifying variables in the relationship between fees and professional service output quality. The identified variables can be monitored and controlled by researchers during future investigations. Additionally, a conceptual methodology was proposed to assist researchers to determine the effect of fees on professional service output quality. The flexibility of the conceptual methodology enables it to comprehensively investigate other key variables (apart from fees) impacting on professional service output quality.
Authentic leader(ship) development and leaders' psychological well-being: an outcome-wide analysis
Authors: Yemiscigil Ayse , Born Dana , Snook Scott , Pate Emily 
Published: October 2022

PurposeDespite a fast-growing interest in leadership development programs, there is limited research on the impacts of leadership development and a narrow focus on professional competencies as outcomes. The authors’ aim was to test whether authentic leadership development (ALD), an identity-based leadership development approach, is associated with positive changes in leaders' psychological well-being.Design/methodology/approachIn a large sample of leaders (N = 532) from five different ALD programs, the authors conducted a pre-registered outcome-wide analysis and tested within-person changes in key indicators of psychological well-being and explored individual differences moderating these changes.FindingsResults showed significant increases in self-concept clarity, sense of purpose in life and personal growth about two to three weeks after the programs ended. Changes in stress and health were not consistent. These changes did not differ across socio-demographic status (gender, age), work-related factors (leadership, industry and tenure) and most personality factors (extraversion, agreeableness, openness to experience). Those with high emotional variability experienced greater improvements in some outcomes of well-being while individuals with higher income and conscientiousness (who had high baseline self-concept clarity) experienced smaller improvements. Longer follow-up assessments were associated with smaller changes.Originality/valueAs one of the most comprehensive assessments of ALD outcomes to date, this study shows the potential of ALD for improving outcomes beyond leadership skills, the well-being of leaders, highlighting the return on value in leadership development and pointing to learning and development as a workplace well-being intervention.

Published: October 2022

Purpose
This paper aims to investigate how graduates’ perceptions of self-service technology and perceived job performance can be used to assess university service quality. Also, this study examines the mediating role of perceived job performance on the effect of university service quality on graduates’ satisfaction and loyalty.

Design/methodology/approach
A quantitative methodology was adopted where university graduates’ perceptions of self-service technology and job performance were used to assess the level of the university’s service quality. Through a cross-sectional survey, data were collected from 280 university graduates employed in Chinhoyi town, Zimbabwe, during the period between August and December 2021.

Findings
This study’s findings indicate that self-service technology influences university service quality which in turn impacts on graduates’ perceived job performance, satisfaction and loyalty. Graduates' perceived job performance was also found to partially mediate the effect of university service quality on satisfaction and loyalty among graduates.

Research limitations/implications
This study’s results are instrumental to enable university’s management in developing economies to adopt and improve self-service technologies as this enhances university service quality and graduates’ perceived job performance, satisfaction and loyalty.

Originality/value
This paper provides new insights, that is, the incorporation of graduates’ perceptions of self-service technology and job performance in assessing the university’s service quality. This research further clarifies the function of graduates’ perceived job performance in mediating the effect of university service quality on graduate satisfaction and loyalty.
